Abstract:Objective To explore the application value of a nursing emergency plan combined with diversified nursing in the management of postpartum hemorrhage.Methods A retrospective analysis was conducted on the clin-ical data of 68 women who experienced postpartum hemorrhage during delivery at Xiamen Fifth Hospital from January 2023 to December 2024.Based on the nursing plan,the patients were divided into an observation group(n=34,receiving a nursing emergency plan combined with diversified nursing)and a control group(n=34,receiving routine nursing).The two groups were compared in terms of perioperative indicators,hemostatic effectiveness,negative emotions(measured by the Self-Rating Depression Scale[SDS]and Self-Rating Anxiety Scale[SAS]),quality of life,and nursing satisfaction.Re-sults Compared with the control group,the observation group had significantly less postpartum bleeding(P<0.001),shorter hemostasis time,surgery duration,and hospitalization time(P<0.001).The hemostasis success rate was higher in the observation group(97.06%vs.79.41%,P<0.05).Before the intervention,there were no significant differences in SDS scores,SAS scores,and quality of life(physical function,social function,mental health,and overall health)between the two groups(P>0.05).After the intervention,both groups showed a significant reduction in SDS and SAS scores(P<0.001),with a significant improvement in quality of life scores across all dimensions(P<0.05).Compared to the control group,the observation group had significantly lower SDS and SAS scores(P<0.001),and significantly higher scores in physical function,social function,mental health,and overall health(P<0.001).Additionally,the nursing satisfaction in the ob-servation group was significantly higher than in the control group(97.06%vs.73.53%,P<0.05).Con-clusion For women experiencing postpartum hemor-rhage,implementing a nursing emergency plan com-bined with diversified nursing can effectively reduce bleeding volume,shorten bleeding time,improve hemostasis success,alleviate negative emotions,enhance quality of life,and increase nursing satisfaction.

Abstract:Objective To investigate the impact of a structured rescue strategy on blood gas parameters,compli-cations,and quality of life in patients with cancer complicated by acute pulmonary embolism.Methods Seventy-two patients with cancer complicated by acute pulmonary embolism admitted to Longyan Second Hospital in Fujian Province from January 2023 to February 2025 were selected as the study subjects.They were randomly divided into two groups us-ing a random number table:the observation group(36 cases)received the structured rescue strategy,and the control group(36 cases)received the conventional rescue protocol.Blood gas parameters,complication incidence,and quality of life were compared between the two groups.Results Before treatment,there were no statistically significant differences in the levels of PaO₂,PaCO₂,and SpO₂ between the two groups(P<0.05).After treatment,PaO₂ and SpO₂ significantly increased(P<0.001),and PaCO₂ significantly decreased(P<0.001)in both groups.Compared with the control group,the observation group showed a more significant increase in PaO₂ and SpO₂ and a more significant decrease in PaCO₂,with all differences being statistically significant(P<0.05).Before treatment,there were no significant differences in the scores of each dimen-sion of the SF-36 scale between the two groups(P>0.05).One month after treatment,the scores of all SF-36 dimensions significantly increased in both groups(P<0.001).Furthermore,the scores of the observation group were significantly higher than those of the control group in all eight dimensions:Physical Functioning(P=0.006),Role-Physical(P=0.002),Bodily Pain(P=0.001),General Health(P<0.001),Vitality(P=0.002),Social Functioning(P=0.001),Role-Emotional(P=0.001),and Mental Health(P=0.004).The complication incidence in the observation group was significantly lower than that in the control group(8.33%vs.27.78%,P=0.032).Conclusion The structured rescue strategy can effectively improve blood gas parameters,reduce the complication incidence,and enhance the quality of life in patients with cancer complicated by acute pulmonary embolism.

Abstract:Objective To investigate the effects of non-invasive positive pressure ventilation(NIPPV)as an ad-junctive therapy on clinical efficacy,cardiac function,serological markers,and blood gas parameters in patients with severe acute heart failure(AHF)complicated by respiratory failure(RF).Methods Fifty-two patients with severe AHF compli-cated by RF admitted between January 2022 and December 2024 were selected and randomly divided into a control group(n=26)and a study group(n=26)using a random number table.The control group received conventional drug therapy(diu-retics,vasodilators,inotropes,etc.)and oxygen therapy.The study group received NIPPV in addition to the control group's treatment.After 7 days of treatment,clinical efficacy,cardiac index(CI),left ventricular ejection fraction(LVEF),left ventricular end-diastolic dimension(LVEDd),left ventricular end-systolic dimension(LVEDs),serum levels of N-terminal pro-B-type natriuretic peptide(NT-proBNP),C-reactive protein(CRP),cardiac troponin I(cTnI),creatine kinase-MB(CK-MB),and blood gas parameters[oxygenation index(OI),arterial partial pressure of oxygen(PaO₂),oxygen saturation(SpO₂),partial pressure of carbon dioxide(PaCO₂)]were compared between the two groups.Results Before treatment,there were no statistically significant differences in cardiac function,serological,or blood gas parameters between the two groups(P>0.05).After treatment,the study group had higher LVEF and CI,and lower LVEDs and LVEDd than the control group(P<0.05).The study group had higher OI,PaO₂,and SpO₂,and lower PaCO₂ than the control group(P<0.05).The study group had lower serum levels of NT-proBNP,CRP,cTnI,and CK-MB than the control group(P<0.001).The total clinical effective rate was significantly higher in the study group than in the control group(96.15%vs.69.23%,P=0.028).Conclusion On the basis of con-ventional drug therapy,the combined use of NIPPV can more effectively improve clinical symptoms,significantly enhance cardiac function,reduce levels of myocardial injury and inflammatory markers,and rapidly correct hypoxemia and carbon dioxide retention in patients with severe AHF complicated by RF,demonstrating definite clinical efficacy.

Abstract:Objective To investigate the clinical efficacy and safety of combining ulinastatin with standard intra-venous insulin therapy in the treatment of patients with severe diabetic ketoacidosis(DKA).Methods A total of 86 pa-tients with severe DKA admitted between January 2021 and October 2024 were enrolled.According to the random number table method,they were divided into a control group(n=43,receiving standard intensive DKA treatment)and an observa-tion group(n=43,receiving intravenous infusion of ulinastatin 100,000 IU twice daily for 5-7 days in addition to the con-trol group's treatment).The metabolic crisis correction times(time to blood ketone<0.6 mmol/L,time to pH>7.3),changes in inflammatory markers(CRP,IL-6,PCT),blood glucose levels and improvement time,hospital stay,and incidence of adverse reactions were compared between the two groups.Results On the 3rd and 7th day after treatment,the levels of CRP,IL-6,and PCT in the observation group were significantly lower than those in the control group(P<0.05).The time to achieve blood glucose target,time for urine ketone bodies to turn negative,time for acidosis correction,and hospital stay in the observation group were significantly shorter than those in the control group(P<0.001).After 2 weeks of treatment,the levels of fasting blood glucose(P<0.05)and 2-hour postprandial blood glucose(P<0.001)in the observation group were also significantly lower than those in the control group.The total incidence of adverse reactions in the observation group was significantly lower than that in the control group(9.30%vs.34.88%,P=0.004).Conclusion Early combination of ulinastatin with standard therapy can effectively suppress systemic inflammatory response in patients with severe DKA,accelerate the metabolic correction of ketoacidosis and blood glucose control,shorten hospital stay,and demonstrates good safety.It is an effective adjuvant treatment for improving the prognosis of severe DKA.

Abstract:Objective To investigate the causal relationship between immunophenotypes and the risk of disease onset,specifically acute pancreatitis,using a two-sample Mendelian randomization approach.Methods Data on 731 immune cell phenotypes and acute pancreatitis were obtained from the FinnGen database and GWAS catalog.The in-verse-variance weighted method,weighted median method,and MR-Egger regression were employed to examine the causal links.The robustness and reliability of the findings were assessed via Cochran's Q test,MR-Egger regression,MR-PRESSO,leave-one-out analysis,and meta-analysis.Results Thirty-four immunophenotypes showed potential causal associations(P<0.05).After Bonferroni correction,ten phenotypes demonstrated significant associations.Among these,seven effector phenotypes(CD19 on CD20-,FSC-A on NKT,CD4 on CD39+CD4+,CD19 on IgD+CD24+,CD25hi CD45RA-CD4 not Treg%CD4+,HLA DR on B cell,CD39 on CD39+CD4+)(OR:1.18～1.41)were significantly asso-ciated with increased risk,while three protective phenotypes(CD28+CD45RA+CD8br%CD8br,CD62L-plasmacytoid DC AC,CD127-CD8br%CD8br)(OR:0.68～0.82)showed a negative association trend(P<6.8×10⁻⁵).Key risk markers included CD19+/CD20-B cells(β=0.26,PIVW=3.8×10⁻⁴)and HLA-DR+B cells(β=0.18,PIVW=6.2×10⁻⁶).Conclusion This two-sample Mendelian randomization study identified ten immunophe-notypes significantly associated with acute pancreatitis(CD19 on CD20-,FSC-A on NKT,CD4 on CD39+CD4+,CD19 on IgD+CD24+,CD25hi CD45RA-CD4 not Treg%CD4+,HLA DR on B cell,CD39 on CD39+CD4+,CD28+CD45RA+CD-8br%CD8br,CD62L-plasmacytoid DC AC,CD127-CD8br%CD8br),providing genetic evidence for understanding its immunoregulatory mechanisms and potential therapeutic targets.

Abstract:Objective To investigate the effects of ulinastatin combined with anti-infective drugs on inflamma-tory factors,immune function,disease severity,and clinical efficacy in patients with biliary severe acute pancreatitis(SAP).Methods A total of 120 biliary SAP patients admitted to our hospital from January 2021 to December 2024 were selected as the study subjects and randomly divided into a control group and an observation group using a random number table,with 60 cases in each group.The control group received conventional treatment(including fasting,fluid replacement,acid suppression,etc.)combined with anti-infective drugs(ceftriaxone sodium+metronidazole);the observation group re-ceived ulinastatin in addition to the control group's treatment.The treatment course for both groups was 7～10 days.Chang-es in inflammatory factors(TNF-α,IL-6,IL-10),immunoglobulins(IgA,IgM,IgG),and pancreatic enzyme indicators(serum amylase,lipase)were compared between the two groups before and after treatment.The APACHE II score was used to assess disease severity before treatment and on days 1,3,and 7 after treatment.The total clinical effective rates were com-pared between the two groups.Results After treatment,the levels of TNF-α,IL-6,serum amylase,and lipase in the ob-servation group were significantly lower than those in the control group,while the levels of IL-10,IgA,IgM,and IgG were significantly higher(all P<0.001).The APACHE II scores of the observation group on days 1,3,and 7 post-treatment were significantly lower than those of the control group(day 1:P=0.032;day 3:P=0.001;day 7:P<0.001).The overall clinical effective rate was significantly higher in the observation group compared to the control group(95.00％vs.80.00％,P=0.013).Conclusion In the treatment of patients with biliary severe acute pancreatitis,ulinastatin com-bined with anti-infective drugs can effectively control inflammatory factor levels,enhance immune function,effectively reduce serum amylase and lipase levels,and achieve significant clinical efficacy.

Abstract:Objective This study evaluates the radiation shielding performance of different combinations of metal substrates and ceramic coatings,focusing on the application potential of lead-free and low-lead ceramic coatings in radiation protection.The goal is to provide scientific evidence for the development of environmentally friendly and efficient radiation shielding materials.Methods Four metal substrates of aluminum,copper,stain-less steel and titanium were selected with lead-free,lead-free,composite and nano-ceramic coatings,and the sam-ples were prepared by spraying method.The transmission dose rate(I)and photon attenuation rate(μ)of different materials were measured under 80 kV,120 kV,160 kV X-ray and 137Cs y-ray conditions,respectively.Lead equiv-alent was calculated to evaluate the shielding effect,and Pearson correlation analysis was performed to determine the linear relationship between the data.Results At 80 kV X-ray conditions,there is a positive correlation be-tween I and μ in most samples,and a strong positive correlation between lead equivalent and μ.Under the condition of 120 kV X-ray,the I values of B2 and C2 of lead-free ceramic coating samples are both low,520 μSv/h and 510μSv/h,respectively,while the μ values of both samples are high,0.70 mm 1 and 0.72 mm-1,respectively,indi-cating that the shielding properties of lead-free ceramic coating samples are strong.However,the I of low-lead ceramic coating sample D1 is the highest,reaching 710 μSv/h,μ is 0.35 mm-1,and lead equivalent is 0.23 mmPb,indicating poor attenuation effect.Under the condition of 160 kV X-ray,I of all samples is generally higher,and the correlation coefficient is concentrated between 0.60 and 0.79,indicating that all samples show higher I and μ,and the increase of μ directly affects the increase of I.In the 137Cs y-ray condition,the I of y-rays is generally lower and the μ is generally higher than that of X-rays.Under 137Cs γ-ray conditions,the I,μ and Pb equivalent of B2 are 500 μSv/h,0.76 mm 1 and 0.50 mmPb respectively,indicating that B2 has strong attenuation to y-rays.In con-trast,the low-lead ceramic coating sample D1 has an I of 690 μSv/h,a μ of 0.40 mm-1,and a lead equivalent of 0.26 mmPb,indicating better y-ray transmission and weak attenuation effect.Conclusion Lead-free ceramic coatings show superior radiation protection ability under experimental conditions,especially the shielding effect of high-en-ergy X-rays and y-ray is better than that of traditional low-lead coatings.

Abstract:Objective To investigate the efficacy and safety of a portable video laryngoscope for endotracheal intubation in critically ill patients during night-time prehospital emergency care.Methods Forty critically ill patients requiring prehospital emergency endotracheal intubation admitted to our hospital from January 2023 to January 2025 were selected as the study subjects.They were randomly divided into an observation group(n=20)and a control group(n=20)using a random number table.The control group underwent intubation using a traditional laryngoscope,while the observa-tion group underwent intubation using a portable video laryngoscope.The first-attempt success rate,overall success rate,glottic exposure time,total intubation time,changes in hemodynamic parameters[heart rate(HR),mean arterial pressure(MAP)]at different time points before and after intubation,and the incidence of complications were compared between the two groups.Results The first-attempt success rate(85.00%vs.50.00%)and the overall success rate(95.00%vs.70.00%)in the observation group were significantly higher than those in the control group(P<0.001).The glottic expo-sure time and total intubation time in the observation group were significantly shorter than those in the con-trol group(P<0.001).Repeated measures analysis of variance showed that the time effect and interaction effect for both HR and MAP were statistically significant in both groups(P<0.05).At immediately after intubation and 2 minutes after intubation,the levels of HR and MAP in the observation group were significantly lower than those in the control group(P<0.05).Furthermore,the total incidence of complications in the observation group was significantly low-er than that in the control group(10.00%vs 35.00%,P<0.05).Conclusion In night-time prehospital emergency care,compared with the traditional laryngoscope,the portable video laryngoscope can significantly improve the success rate and efficiency of endotracheal intubation,effectively reduce the hemodynamic impact on patients,and lower the risk of compli-cations,demonstrating higher clinical application value and safety.

Abstract:Objective To investigate the effect of psychological intervention combined with symptom assess-ment nursing on the prognosis of patients with sinusitis complicated by acute asthma attacks during emergency treat-ment.Methods A total of 40 patients with sinusitis complicated by acute asthma attacks admitted to Zhongshan Hos-pital affiliated with Xiamen University from January 2021 to December 2024 were selected as study subjects.According to the different nursing interventions implemented,they were divided into an observation group(20 cases)and a control group(20 cases).The study compared the efficacy-related indicators,lung function,and psychological status between the two groups.Results Compared with the control group,the observation group had fewer asthma attacks,shorter asthma remission time,shorter sinusitis symptom relief time,and shorter hospital stay(P<0.001).Upon admission,there were no significant differences between the two groups in FEV1(P=0.470),FVC(P=0.579),PEF(P=0.401),FEV1/FVC(P=0.539),SAS score(P=0.732),and SDS score(P=0.857).After 7 days of treatment,lung function indicators and psychological status scores improved in both groups,with the observation group showing significantly higher FEV1(P<0.001),FVC(P=0.004),PEF(P=0.002),and FEV1/FVC(P<0.001),and significantly lower SAS score(P<0.001)and SDS score(P<0.001)compared to the control group.Conclusion In the emergency treatment of patients with sinusitis complicated by acute asthma attacks,psychological intervention combined with symptom assessment nursing can effectively shorten the time for symptom relief,improve the patients'lung function,and alleviate anxiety and depression.

Abstract:Objective To explore the efficacy of amiodarone in the emergency treatment of heart failure(HF)complicated with rapid atrial fibrillation(AF).Methods One hundred patients with HF and rapid AF admitted to Ant-ing Hospital,Jiading District,Shanghai,from January 2023 to May 2025 were selected as the study subjects.Based on the emergency treatment protocol,they were divided into a control group(n=50)and an observation group(n=50).Ventricular rates at different time points,AF conversion status,treatment efficacy,and incidence of adverse reactions were compared between the two groups.Results Before treatment,there was no significant difference in ventricular rate between the two groups(P=0.310).After treatment,the ventricular rates in both groups showed a decreasing trend over time.At 30 min,1 h,6 h,12 h,and 24 h post-treatment,the ventricular rates in the observation group were significantly lower than those in the control group(P<0.001).Compared to the control group,the observation group had significantly higher conver-sion rates within 3 hours(P=0.046),within 3-8 hours(P=0.026),and the total conversion rate(P=0.006),a significantly shorter conversion time(P<0.001),and a significantly higher overall clinical effective rate(94.00%vs.76.00%,P=0.012).There was no significant difference in the total incidence of adverse reactions between the two groups(10.00%vs.14.00%,P=0.538).Conclusion In the emergency treatment of patients with HF and rapid AF,amiodarone can rapidly and effec-tively reduce ventricular rate,restore sinus rhythm more quickly,demonstrates significant clinical efficacy,and has a high safety profile.

Abstract:Objective To compare the mid-term efficacy of early minimally invasive surgery[percutaneous ver-tebroplasty(PVP)/percutaneous kyphoplasty(PKP)]versus standardized conservative treatment in elderly patients with osteoporotic vertebral compression fractures(OVCF).Methods The clinical data of 60 elderly OVCF patients admitted to Zhao'an County Hospital,Fujian Province,from January 2017 to December 2024 were retrospectively analyzed.Based on the treatment regimen,the patients were divided into an observation group(early minimally invasive surgery group,30 cases)and a control group(standardized conservative treatment group,30 cases).The time to ambulation,length of hospi-tal stay,visual analog scale(VAS)score for pain,lumbar range of motion(ROM),Oswestry Disability Index(ODI)score,36-Item Short Form Health Survey(SF-36)score,complication rates,and incidence of long-term adverse events were com-pared between the two groups.Results The time to ambulation and length of hospital stay in the early minimally inva-sive surgery group were significantly shorter than those in the standardized conservative treatment group(P<0.001).At 1 month and 3 months after treatment,the VAS scores in the early minimally invasive surgery group were significantly lower than those in the conservative treatment group(P<0.001).At 3 months after treatment,the lumbar flexion angle,extension angle,and SF-36 scores in the early minimally invasive surgery group were significantly higher than those in the conserva-tive treatment group(P<0.001),while the ODI score was significantly lower than that in the conservative treatment group(P<0.001).The total incidence of peritreatment com-plications(6.67%vs.26.67%,P=0.038)and the total incidence of long-term adverse events within the 12-month follow-up period(10.00%vs.26.67%,P=0.044)were signifi-cantly lower in the early minimally invasive surgery group than in the standardized conservative treatment group.Con-clusion For elderly OVCF patients without neurological impairment,compared with standardized conservative treatment,early minimally invasive surgery can relieve pain more rapidly,promote functional recovery,shorten hospital stay,and effectively reduce the risks of peritreatment complications and mid-term adverse events.

Abstract:Objective To explore the application effect and value of the integrated medical-nursing model in emergency hemodialysis treatment.Methods A total of 60 patients who received emergency hemodialysis treatment in the Hemodialysis Room of the Second Affiliated Hospital of Guizhou Medical University from March 2023 to March 2025 were selected as the study subjects.They were divided into an observation group(integrated medical-nursing model,n=30)and a control group(conventional hemodialysis care,n=30)using a random number table method.The Kt/V value,electrolyte levels,nutritional status,and satisfaction were compared between the two groups.Results Before treatment,there were no significant differences in Kt/V value,K+,Na+,Ca2+,body mass index,triceps skinfold thickness,or mid-up-per arm circumference between the two groups(P>0.05).After treatment,both groups showed improvements in Kt/V value,K+,Ca2+,and nutritional indicators.Compared with the control group,the observation group had lower K+levels(P<0.001),and higher Kt/V value(P<0.001),Ca2+levels(P=0.002),body mass index(P=0.018),triceps skinfold thickness(P=0.001),and mid-upper arm circumference(P=0.001).There was no significant difference in Na+levels between the two groups(P=0.656).Compared with the control group,the observation group had higher satisfaction(93.33%vs.73.33%,P=0.038).Conclusion In emergency hemodialysis treatment,the integrated medical-nursing model is beneficial for im-proving patients'Kt/V value,nutritional status,maintaining electrolyte balance,and enhancing nursing satisfaction.

Abstract:Objective To explore the high-risk factors and key points in the clinical diagnosis and treatment of ovarian corpus luteum rupture.Methods A total of 84 patients with gynecological acute abdomen admitted to Longyan People's Hospital from April 2022 to April 2024 were selected as the study subjects,including 49 patients with ovarian corpus luteum rupture and 35 patients with ruptured ectopic pregnancy.The general data,abdominal pain characteristics,vaginal bleeding and shock status,ultrasonographic findings,hematological indicators,treatment,and prognosis were com-pared between the two groups.Results Patients in both groups primarily presented with unilateral lower abdominal pain(P>0.05).However,the corpus luteum rupture group had significantly lower VAS scores for abdominal pain,a higher pro-portion of dull pain,and a shorter duration of pain(P<0.001).The incidence of vaginal bleeding and shock in the corpus luteum rupture group was significantly lower than that in the ruptured ectopic pregnancy group(P<0.05).Ultrasonography showed that the mass in the corpus luteum rupture group was smaller(P<0.001)and more frequently exhibited annular or semi-annular blood flow signals(P=0.001).Regarding hematological indicators,the serum β-HCG was negative in the cor-pus luteum rupture group,the decrease in hemoglobin was smaller(P<0.001),and the increase in white blood cell count was lower(P<0.001).In terms of treatment,the conservative treatment rate was higher in the corpus luteum rupture group(P<0.05).There was no significant difference in the total effective rate or complication rate between the two groups(P>0.05).Conclusion Differentiating ovarian corpus luteum rupture from ruptured ectopic pregnancy requires comprehen-sive consideration.Corpus luteum rupture is charac-terized by negative serum β-HCG,relatively mild and transient abdominal pain,lower incidence of vaginal bleeding and shock,smaller adnexal mass on ultrasonography often with annular blood flow signals,and a lesser degree of hemoglobin decrease.Clinical diagnosis and treatment should inte-grate the above characteristics to individualize the choice between conservative and surgical management.

Abstract:Objective To analyze the independent risk factors influencing the short-term prognosis of patients with spontaneously ruptured hepatocellular carcinoma(HCC)undergoing emergency transcatheter arterial chemoembolization(TACE).Methods The clinical data of 60 patients with spontaneously ruptured HCC who underwent emergency TACE at our hospital from March 2022 to March 2025 were retrospectively analyzed.Based on their survival status at 3 months postoperative-ly,they were divided into a favorable prognosis group(43 cases)and a poor prognosis group(17 cases).Baseline characteristics were compared between the two groups,and univariate and multivariate Logistic regression analyses were performed to identify independent risk factors affecting short-term prognosis.Results Univariate analysis showed that tumor diameter,Child-Pugh grade,TNM stage,alpha-fetoprotein(AFP),white blood cell count(WBC),hemoglobin(Hb),and prothrombin time(PT)were significantly different between the two groups(P<0.05).Multivariate Logistic regression analysis confirmed that increased tu-mor diameter(OR=1.610,95%CI:1.225～2.107),elevated Child-Pugh grade(OR=1.624,95%CI:1.263～2.091),and decreased Hb level(OR=0.658,95%CI:0.487～0.832)were independent risk factors for poor prognosis(P<0.001).Conclusion Large tumor diameter,high Child-Pugh grade,and low admission Hb level are independent risk factors for poor short-term prognosis following emergency TACE in patients with ruptured HCC.Clinical attention should focus on high-risk patients with these char-acteristics,and comprehensive intervention measures should be implemented to improve their prognosis.

Abstract:Objective To compare the clinical efficacy of expandable intramedullary nails and traditional interlock-ing intramedullary nails in the treatment of adult traumatic femoral shaft fractures.Methods A total of 80 patients with traumatic femoral shaft fractures admitted to our hospital from January 2022 to December 2024 were selected and random-ly divided into an observation group(40 cases,treated with expandable intramedullary nail fixation)and a control group(40 cases,treated with interlocking intramedullary nail fixation).The operative time,hospitalization time,fracture healing time,joint function recovery time,postoperative visual analog scale(VAS)pain scores,Lower Extremity Functional Scale(LEFS)scores,modified Barthel index,and complication rates were compared between the two groups.Results The operative time,hospitalization time,fracture healing time,and joint function recovery time in the observation group were significant-ly shorter than those in the control group(all P<0.001).At 1 day,3 days,7 days,and 1 month postoperatively,the VAS scores in the observation group were significantly lower than those in the control group(all P<0.05).At 3 months and 6 months postoperatively,the LEFS scores and modified Barthel index in the observation group were significantly higher than those in the control group(all P<0.05).There was no statistically significant difference in the overall complication rate between the two groups(observation group:2.50%vs.control group:10.00%,P>0.05).Conclusion Compared with traditional interlocking intramedullary nails,the use of expandable intramedullary nails in the treatment of adult trau-matic femoral shaft fractures significantly shortens the surgical and rehabilitation process,effectively reduces early postoperative pain,promotes the recovery of lower limb function and daily living activities,and does not increase the risk of complications.It is a safe and effective minimally invasive internal fixation option.

Abstract:Objective To investigate the clinical efficacy of high-flow nasal cannula oxygen therapy(HFNC)in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD)complicated by type Ⅱ respiratory failure.Methods A total of 150 patients with AECOPD and type Ⅱ respiratory failure admitted to the Third People's Hospital of Bengbu City,Anhui Province,from August 2023 to January 2025 were selected as the study subjects.Using a random number table method,all patients were divided into an observation group(HFNC)and a control group(non-invasive positive pressure ventilation),with 75 patients in each group.Blood gas parameters,pulmonary function,and adverse reac-tions were compared between the two groups.Results Before treatment,there were no significant differences in arterial partial pressure of oxygen(PaO₂),arterial partial pressure of carbon dioxide(PaCO₂),pH value,forced expiratory volume in one second(FEV₁),forced vital capacity(FVC),or the FEV₁/FVC ratio between the two groups(P>0.05).After 7 days of treatment,both groups showed significant increases in PaO₂,pH,FEV₁,FVC,and FEV₁/FVC,and a significant decrease in PaCO₂(all P<0.05).Moreover,the observation group had significantly higher PaO₂,pH,FEV₁,FVC,and FEV₁/FVC,and significantly lower PaCO₂ than the control group(P<0.001).The relief times for dyspnea,cough,and expectoration in the observation group were significantly shorter than those in the control group(P<0.001).The incidence of adverse reactions in the observation group was sig-nificantly lower than that in the control group(10.67％vs.26.67％,P<0.05).Conclusion In the treatment of patients with AECOPD and type Ⅱ respiratory failure,HFNC can effectively improve blood gas parameters and respiratory function,promote the relief of clinical symptoms,and exhibits high safety.

Abstract:Modern warfare is profoundly evolving towards intellectualization,multi-domainization,and hybridiza-tion,leading to complex casualty conditions,pan-domain distribution,and stringent requirements for treatment timeliness.This has plunged traditional medical service systems into disruptive challenges such as resource shortages,delayed evac-uation,and functional failure in extreme environments.The deep integration of artificial intelligence robot technology is a key and essential path to break this predicament.Through the analysis of the evolution of warfare modes and the pain points in traditional treatment,this paper introduces the advantages of artificial intelligence robots in various stages such as battlefield search and rescue,evacuation,and treatment,and deeply analyzes their application demands in medical service support,providing a theoretical basis and important reference for constructing a modern and intelligent medical service support system.

Abstract:Objective To investigate the clinical value of arthroscopic-assisted reduction and fixation in the treatment of ankle fractures.Methods Sixty patients with ankle fractures admitted to Lianjiang County General Hospital from March 2022 to March 2025 were selected as the study subjects.According to the different methods of open reduction and internal fixation,they were divided into a control group(traditional open reduction and internal fixation,30 cases)and an observation group(arthroscopic-assisted reduction and fixation,30 cases).Postoperative pain levels,ankle joint function and range of motion recovery,and the incidence of complications were compared between the two groups.Results After treatment,the VAS scores in both groups showed a decreasing trend.Compared with the control group,the VAS scores in the observation group were significantly lower on postoperative day 1(P=0.023),day 3(P=0.001),and day 5(P<0.001).After treatment,the AOFAS scores,plantar flexion range of motion,and dorsiflexion range of motion in both groups showed an increasing trend.Compared with the control group,the AOFAS scores,plantar flexion range of motion,and dorsiflexion range of motion in the observation group were significantly higher at 1 month,3 months,6 months,and 12 months postoperatively(P<0.05).The total incidence of complications in the observation group was significantly lower than that in the control group(10.00%vs.33.33%,P=0.028).Conclusion In the treatment of ankle fracture patients,arthroscopically assisted reduction and fixation is superior to traditional open reduction and internal fixation in terms of alleviating postoperative pain,promoting ankle func-tion recovery,and reducing the risk of postoperative complications.
