Objective:To construct and validate a predictive model for postoperative pulmonary complications (PPCs) in patients undergoing robot-assisted laparoscopic urological surgery.Methods:This retrospective study included the medical records of 932 patients who underwent robot-assisted laparoscopic urological surgery at the First Affiliated Hospital of Zhejiang University School of Medicine from January 2020 to February 2022. The patients were divided into a training group ( n=559) and a validation group ( n=373) at a 6∶4 ratio. Logistic regression analysis was used to determine the independent risk factors for PPCs, and a nomogram prediction model was constructed based on these factors. The performance of the model was evaluated using the receiver operating characteristic curve and calibration curve, and the clinical benefit was assessed using the clinical decision curve analysis. Results:The independent risk factors for PPCs included advanced age (>60 yr), smoking history, respiratory tract infection within 1 month, preoperative low SpO 2 (<96%), and prolonged length of postoperative hospital stay ( P<0.05), and the body mass index (18.5-<28.0 kg/m 2) was a protective factor. The nomogram prediction model developed based on the aforementioned 6 influencing factors had an area under the receiver operating characteristic curve of 0.81 (95% confidence interval 0.76-0.86) in training group and 0.80 (95% confidence interval 0.75-0.86) in validation group. The calibration curve indicated a good consistency between the predicted and actual occurrence curves, and the clinical decision curve analysis showed good accuracy and net benefit of the prediction model. Conclusions:The predictive model for PPCs is successfully constructed based on age, low body mass index, smoking history, history of respiratory tract infection within 1 month, preoperative low SpO 2 and prolonged length of postoperative hospital stay and has good predictive performance in patients undergoing robot-assisted laparoscopic urological surgery.

Objective To explore the influence of function-oriented training combined with proprio-ceptive neuromuscular facilitation(PNF)technique on stroke patients during convalescence.Methods A total of 106 patients with cerebral infarction during convalescence admitted to the First Hospital of Hebei Medical University and Hebei provincial of Tradifional Chinese Medicine Hospital from January 2021 to December 2023 were recruited and then randomly divided into combined group(53 cases)and control group(53 cases).The control group only received function-oriented training,while the combined group received function-oriented training combined with PNF technique.The neurological function,balance function,walking ability and motor function were compared before and after intervention and between groups.Results After intervention,the NIHSS score and central nervous system specific protein(S100β)and neuron specific enolase(NSE)levels were significantly lower in the two groups than those before intervention(P＜0.05),and the score and levels after intervention were significantly lower in combined group than the control group(13.28±0.86 vs 15.76±0.94,P＜0.01;1.56±0.24 μg/L vs 1.79±0.23 μg/L,P＜0.0 1;20.46±3.12 μg/L vs 24.75±3.69 μg/L,P＜0.01).The Berg balance scale(BBS)score,step speed and step length in 10-meter walking test(10 MWT)and Fugl-Meyer assessment score were significantly higher in both groups after intervention than those before intervention(P＜0.05),and the above indicators in the combined group were obviously higher than those in refer-ence group after intervention(P＜0.05,P＜0.01).Conclusion For the patients during cerebral infarction convalescence,function-oriented training combined with PNF technique can not only promote the recovery of neurological function,but also enhance the balance ability and walking a-bility,and improve the limb motor function.

Objective To investigate the current status of home medicine cabinet management and unmet needs for home-based pharmaceutical services among elderly hypertensive patients in Hubei Province,and to provide evidence for optimizing home pharmaceutical care models.Methods From July 2022 to March 2023,310 elderly hypertension patients across Hubei Province were enrolled.Pharmacists conducted home visits to administer structured questionnaires capturing demographics and blood pressure control rates,perform medication categorization and quality assessments of home medicine cabinets and document cabinet management issues in real-time.Results Among 290 valid questionnaires,binary logistic regression revealed better blood pressure control in non-working and non-smoking individuals.Medicine cabinet audits identified three critical issues:failure to separate Chinese and chemical medicines,duplicate medications with similar ingredients and missing original packaging.Post-intervention,all cabinets demonstrated proper medication categorization and storage compliance.Conclusions Significant medication safety hazards exist in elderly hypertensive patients'home medicine cabinets.Pharmacist-led home interventions effectively cleared substandard medications and improved medication safety.Future home pharmaceutical services should focus on optimizing cabinet management protocols,enhancing medication safety awareness and personalizing pharmaceutical care to ensure precise and effective home-based medication management.

Objective To explore the value of peripheral blood circulating DNA in predicting the efficacy and prognosis of immunotherapy for advanced non-small cell lung cancer.Method A retrospective study was conducted on 78 NSCLC patients who were admitted to the Respiratory and Critical Care Medicine Department of the First Affiliated Hospital of Hebei North University and were treated with tirelizumab for advanced driver gene negativity from January 2021 to December 2021.After 2 cycles of immunotherapy,the efficacy was evaluated according to the Solid Tumor Efficacy Evaluation Criteria(RECIST 1.1),including complete remission,partial remission,disease stability,and disease progression.CR and PR patients were defined as the experimental group(n=48)Other patients were defined as the control group(n=30),and the ctDNA levels in peripheral blood were measured before and after treatment in both groups.ROC curves were used to analyze the predictive value of periph-eral blood ctDNA levels for achieving objective remission after immunotherapy.All patients were followed up and their progression free survival were calcutated.Using univariate and multivariate regression analysis identified the factors affecting the prognosis of patients after immunotherapy.Using Spearman correlation coefficient analyzed the correlation between ctDNA levels and PFS.Kalplan Meier survival curve were used for survival analysis.Result The peripheral blood ctDNA levels before and after treatment in the experimental group were(4.47±1.21)ng/μL and(2.65±1.14)ng/μL,respectively(t=7.559,P<0.001),while those in the control group were(4.54±1.15)ng/mL and(4.29±1.57)ng/μL,respectively(t=0.699,P=0.487).There was no statistically significant difference in peripheral blood ctDNA levels between the two groups before treatment(t=-0.25,P=0.801).The peripheral blood ctDNA levels in the experimental group decreased compared to the control group after treatment(t=-5.35,P<0.001).The ROC curve analysis showed that the area under the curve for predicting objective remission after immunotherapy based on peripheral blood ctDNA levels was 0.819,with a sensitivity of 81.3%and specificity of 80%.Peripheral blood ctDNA levels were negatively correlated with progression free survival(r=-0.784,P=0.000).Single factor COX regression was used to analyze the clinical and pathological characteristics and ctDNA levels of enrolled patients,and the results showed that the maximum tumor diameter was greater than 5 cm(HR=0.501,95%CI:6.731～35.567)Tumor stage IV(HR=0.392,95%CI:0.227～0.677),treatment approach(HR=15.473,95%CI:6.731～35.567),and ctDNA levels(HR=4.657,95%CI:3.182～6.555)are all influencing factors for PFS in advanced NSCLC patients after immunotherapy.Multiple factor analysis was conducted on the appeal indicators with statistical differences,and the results showed that treatment approach(HR=2.981,95%CI:1.019～8.722)and peripheral blood ctDNA levels(HR=3.918,95%CI:2.619～5.861)It is an independent influencing factor of PFS in advanced NSCLC patients.The Kalplan Meier survival curve was used for analysis,and the results showed that the median PFS of the treatment effective group was 8.4 months,while the median PFS of the control group was 5.4 months.(χ2=49.277,P=0.000).Conclusion Immunotherapy combined with chemotherapy can enhance the ability to kill tumor cells,and peripheral blood ctDNA levels can evaluate the efficacy and prognosis of immunotherapy,which can be used to guide immunotherapy in advanced NSCLC patients.

Objective To investigate the correlation between the expression of long non-coding ribonucleic acid growth arrest specific 5(lncRNA GAS5),phospholysine phosphohistidine inorganic pyrophosphate phos-phatase(LHPP)and epithelial-mesenchymal transition(EMT)in cancer tissues of patients with non-small cell lung cancer(NSCLC)and its clinical significance.Methods Cancer tissues and adjacent tissues of 90 patients with NSCLC who underwent surgical resection in the First Hospital Affiliated to Hebei North College from June 2018 to January 2020 were collected.The expressions of lncRNA GAS5,LHPP and EMT-associated pro-teins[E-calmodulin(E-Cad),N-calmodulin(N-Cad),and vimentin(VIM)]were detected by real-time fluores-cence quantitative polymerase chain reaction.The relationship between lncRNA GAS5 and LHPP mRNA and clinicopathological features in cancer tissues of NSCLC patients was analyzed,and the correlation between ln-cRNA GAS5 and LHPP mRNA and EMT-associated proteins expression in cancer tissues of NSCLC patients was analyzed by Pearson correlation.Kaplan-Meier method was used to plot the survival curves of NSCLC pa-tients with different lncRNA GAS5 and LHPP mRNA expressions,and multivariate Cox regression was used to analyze the prognostic factors of NSCLC patients.Results The expressions of lncRNA GAS5,LHPP mR-NA and E-Cad mRNA in cancer tissues of NSCLC patients were lower than those in adjacent tissues,while the expressions of N-Cad mRNA and VIM mRNA were higher than those in adjacent tissues,with statistical sig-nificance(P＜0.05).Pearson correlation analysis showed that lncRNA GAS5 in cancer tissues of NSCLC pa-tients was positively correlated with E-Cad mRNA expression(r=0.724,P＜0.001),and negatively correla-ted with N-Cad mRNA and VIM mRNA expression(r=-0.699,-0.689).P＜0.001);lncRNA GAS5 was positively correlated with LHPP mRNA expression(r=0.651,P＜0.001).The mRNA expressions of ln-cRNA GAS5 and LHPP in cancer tissues of NSCLC patients with different degrees of differentiation,tumor TNM stage and lymph node metastasis were significantly different(P＜0.05).Kaplan-Meier survival curve a-nalysis showed that the 3-year overall survival rate in the lncRNA GAS5 high expression group[68.18％(30/44)]was higher than that in the lncRNA GAS5 low expression group[36.96％(17/46)].The 3-year overall survival rate in the high LHPP mRNA expression group[67.39％(31/46)]was higher than that in the lowLHPP mRNA expression group[36.36％(16/44)],and the difference was statistically significant(x2=10.274,10.322,P＜0.05).Low differentiation,TNM stage Ⅲ and lymph node metastasis were independent risk factors for death in NSCLC patients,and lncRNA GAS5≥1.32 and LHPP mRNA≥1.12 were independ-ent protective factors(P＜0.05).Conclusion The low expression of lncRNA GAS5 and LHPP mRNA in cancer tissues of patients with NSCLC is related to EMT-associated proteins expression,differentiation de-gree,tumor TNM stage,lymph node metastasis and prognosis,and may become a new target for the diagnosis and treatment of NSCLC.

ObjectiveTo explore the application effect of using the comprehensive index method for occupational health risk assessment in the lead-acid battery enterprises. Methods Convenient sampling method was used to select two lead-acid battery enterprises A and B in Jiangsu Province, with eight key positions including ball grinding, plate casting, pasting, plate coating, plate grinding, plate slicing and brushing, welding and acid charging as the research subjects. Worksite survey of occupational health was conducted in these two lead enterprises, and the levels of lead smoke, lead dust and sulfuric acid in the key positions were detected. The health risk of occupational hazards in the eight key positions was evaluated by a comprehensive index method. Results The time-weighted average concentration (C_TWA) of lead smoke in plate casting and welding positions of enterprise A, the C_TWA of lead dust in plate grinding and plate slicing and brushing positions of enterprise A, the C_TWA of lead dust in plate grinding position of enterprise B, the C_TWA of lead smoke in welding position of enterprise B were exceeded national occupational exposure limits. The risk assessment results of the plate casting, welding, plate grinding and plate slicing and brushing positions were moderate risk, while other positions were low risk in enterprise A. The risk assessment results of the plate grinding and welding positions were moderate risk, while other positions were low risk in enterprise B. Conclusion The results of risk assessment by the comprehensive index method were consistent with the results of occupational hazard factors detection. The comprehensive index method could well evaluate the occupational health risks of lead-acid battery enterprises.

Objective:To investigate the characteristics of gut microbiota in patients with type 2 diabetes (T2DM) complicated by nonalcoholic fatty liver disease (NAFLD).Methods:A total of 74 patients first diagnosed with T2DM at the Endocrinology Department of Peking Union Medical College Hospital from April 2021 to October 2023 were included. Among them, 28 patients had concurrent NAFLD while 46 patients did not. Additionally, 51 healthy controls were matched (HC group). Clinical laboratory parameters were collected, and 16S rRNA sequencing with fecal samples was conducted to compare the differences in gut microbiota across the groups.Results:Compared to the group with T2DM, patients with concurrent T2DM and NAFLD were younger, had higher level of insulin resistance as assessed by the homeostatic model assessment of insulin resistance, higher body mass index (BMI), and higher triglyceride levels. There was no difference in α-diversity across the three groups ( P>0.05), while there was a significant difference in β-diversity ( P=0.03). The Eubacterium coprostanoligenes, Fusicatenibacter, Parasutterella and Tyzzerella 3 were enriched in the group with concurrent T2DM and NAFLD as shown by the relative abundance, while the relative abundance of Flavonifractor was decreased in this group. Tyzzerella 3 abundance was positively correlated with triglyceride and albumin levels and negatively correlated with high-density lipoprotein cholesterol (HDL-C) levels. Conclusion:Patients with T2DM complicated by NAFLD exhibit dysbiosis in gut microbiota composition and specific genera abundance, with Flavonifractor identified as a potential protective factor for T2DM complicated by NAFLD.
