Objective To investigate the value of detection of pelvic floor ultrasound parameters combined with serum relaxin(RLX)and estradiol(E2)levels in diagnosis of female stress urinary incontinence(SUI).Methods A total of 127 puerperae with SUI were selected as SUI group,and another 127 puerperae without SUI during the same period were selected as control group.The pelvic floor ultrasound parameters[bladder neck descent(BND),postvoid residual angle of the bladder-u-rethra(PUVA),and urethral rotation angle(URA)]and serum RLX and E2 levels were compared between the two groups.Binary Logistic regression analysis was used to screen independent influen-cing factors of female SUI,and the diagnostic efficacy of each index alone and their combination for female SUI was analyzed through the receiver operating characteristic(ROC)curve.Results The BND,PUVA,and URA values in the SUI group were greater than those in the control group,the ser-um RLX level was higher,and the serum E2 level was lower,with statistically significant differences(P＜0.05).Binary Logistic regression analysis showed that BND,PUVA,and E2 were independent influencing factors of female SUI(P＜0.05).ROC curve analysis revealed that the areas under the curve(AUCs)for the diagnosis of female SUI by BND,PUVA,URA,RLX,and E2 alone and their combination were 0.775,0.814,0.777,0.749,0.746,and 0.932,respectively.Their sensitivities were 90.6％,86.6％,57.5％,48.8％,100.0％,and 92.1％,and the specificities were 53.5％,68.5％,91.3％,92.1％,49.6％,and 77.2％,respectively.Conclusion The com-bined detection of pelvic floor ultrasound parameters including BND,PUVA,URA,and serum RLX and E2 levels has a high diagnostic value for female SUI.

Objective To investigate a rapid detection method for compressed Nitrous oxide(N2O).Methods The GC-MS system was employed under conventional chromatographic conditions(without replacing standard columns or utilizing headspace sampling)by directly injecting a small gas sample for analysis.N2O identification was performed via NIST spectral library matching,while qualitative and quantitative purity assessments were achieved by monitoring the relative abundance variation of the characteristic fragment ion m/z 30 to eliminate CO2 interference.Results The fragment ion m/z 30 demonstrated specificity for N2O identification.A linear correlation was observed between the peak area of m/z 30 and N2O purity(y=22.741x-1.4565,R2=0.912 6),enabling quantitative purity determination.Additionally,the abundance of m/z30 exhibited a correlation with N2O in CO2 mixtures(y=0.7787x-0.0387,R2=0.722 2).Conclusion Conventional N2O identification typically requires dedicated GC-MS systems,gas-specific chromatographic columns,and headspace sampling.This study successfully utilized routine chromatographic conditions for organic toxicant screening to achieve rapid N2O analysis.The proposed method holds practical significance for compressed N2O identification in forensic and analytical applications.

Objective:To analyze the effect of joint management of type 2 diabetes mellitus (T2DM) between specialty and community under the model of National Diabetes Prevention and Control Center (DPCC).Methods:A total of 2 527 T2DM patients managed by DPCC Pingshan Center of Shenzhen from January 1, 2022 to December 31, 2024 were retrospectively included. After management, the rate of downturn, reexamination rate, blood pressure compliance rate, metabolic indicators (waist circumference, body mass index, fasting blood glucose, glycosylated hemoglobin, blood lipids) and screening rate of chronic complications of diabetes (atherosclerotic cardiovascular disease, microvascular disease, diabetic peripheral neuropathy) were analyzed. Those included 2022 ( n=564), 2023 ( n=1 477), and 2024 ( n=2 527). Results:The downturn rate in 2022, 2023 and 2024 increased year by year (22.8% vs 67.2% vs 89.9%, P<0.01), and the review rate (41.1% vs 62.2% vs 52.7%, P<0.01), complication screening rate (51.6% vs 85.3% vs 62.2%, P<0.01), blood pressure compliance rate (53.1% vs 78.0% vs 67.2%, P<0.01), body mass index compliance rate (13.2% vs 17.3% vs 28.6%, P<0.01), fasting blood glucose meeting rate (46.4% vs 60.2% vs 68.5%, P<0.01), glycated hemoglobin meeting rate (58.4% vs 63.2% vs 45.6%, P<0.01) were relatively improved. Waist circumference compliance rate (30.6% vs 27.7% vs 21.6%) and blood lipid compliance rate (33.6% vs 35.5% vs 31.9%) were not significantly improved, and the review rate, blood pressure compliance rate and complication screening rate in 2024 were lower than those in 2023 and higher than those in 2022. Conclusions:The combined management of type 2 diabetes under the DPCC model has significant effects on improving the down-conversion rate, rediagnosis rate, blood pressure compliance rate, metabolic index compliance rate and the screening rate of diabetes-related chronic complications in patients with diabetes. At the same time, it was also found that with the progress of hierarchical diagnosis and treatment, the review rate, complication screening rate, blood pressure, waist circumference, blood lipid and glycosylated hemoglobin reached the standard of patients decreased compared with the previous situation, which needs to be further analyzed and improved.

Objective To establish the drug use evaluation(DUE)criteria of recombinant human prourokinase(rhPro-UK),and to provide reference for the rational clinical application of rhPro-UK.Methods Based on the drug instructions of rhPro-UK,DUE standard rules were established by referring to relevant guidelines,expert consensus,authoritative literature and expert consultation.The medical records of hospitalized patients treated with rhPro-UK from January 2019 to May 2022 in Xilin Gol League Central Hospital were evaluated by retrospective investigation.The effectiveness of rhPro-UK was evaluated based on clinical outcome,and its safety was evaluated based on the incidence and severity of adverse reactions.Results A total of 230 cases were included,and 4 cases fully met the evaluation criteria(medication indication,medication process,medication results),accounting for 1.74％.There were 226 patients(98.26％)with irrational drug use,mainly manifested in two aspects of drug indication and drug process(administration mode and dosage).Treatment was effective in 221 patients,with an overall effective rate of 96.09％;139 patients experienced adverse reactions,with an incidence rate of 60.43％.Conclusion The clinical use of rhPro-UK in our hospital is irrational in the indication of medication and the process of medication,and the establishment of the DUE standard rules of rhPro-UK can provide a reference to standardize the clinical application of rhPro-UK and promote its rational use.

Objective:To investigate the association between baseline hemoglobin level and early neurologic deterioration(END)after intravenous thrombolysis in patients with acute ischemic stroke(AIS).Methods:Data of AIS patients who received intravenous thrombolytic therapy at multiple hospitals across the country between January 2017 and July 2020 were collected from the online database Acute Stroke Patients for Stroke Management Quality Evaluation(CASE-Ⅱ,NCT04487340).Binary logistic regression analysis was used to study the factors affecting the occurrence of END after intravenous thrombolytic therapy,and the correlation between baseline hemoglobin level and END was investigated by limiting cubic spline curve analysis.Results:A total of 8162 patients were included.Patients with END had lower baseline hemoglobin levels(136 and 140 g/L,P<0.01)and higher rates of anemia(24.2%and 16.9%,P<0.01)compared with non-END patients.Binary logistic regression analysis showed that baseline hemoglobin level(OR=0.995,95%CI:0.991-0.999,P<0.05)and anemia(OR=1.238,95%CI:1.055-1.454,P<0.01)were independently correlated with the occurrence of END after intravenous thrombolysis in AIS patients.Restricted cubic spline regression showed that there was a U-shaped relationship between hemoglobin level and the risk of END after intravenous thrombolysis in AIS patients(P<0.01),although this relationship was only significant in male patients(P<0.05)and not in female patients(P>0.05).Conclusion:There is a correlation between baseline hemoglobin level and the risk of END in AIS patients after intravenous thrombolysis,especially in male patients,in whom both lower and higher hemoglobin level may increase the risk of END.

Objective To establish evaluation of ozagrel sodium by weighted TOPSIS method so as to provide a reference for improving the rational use of ozagrel sodium.Methods Based on the drug instructions,guidelines,relevant literatures and Delphi method,the evaluation criteria for the clinical rationality of ozagrel sodium were formulated.Attribute hierarchical model(AHM)was used to assign weights to the indicators,the weighted TOPSIS method was employed to analyze and evaluate the rationality of 108 patients that discharged from the Third People's Hospital of Henan Province from January 2021 to April 2022.Results The reponse rates of two rounds of expert advice questionnaires were 100％,the authoritative coefficients(Cr)were 0.85,0.83(＞0.70),and the experts fully affirmed the items of the standard.Among the 108 cases evaluated,37 cases(34.26％)were judged to be reasonable,52 cases(48.15％)were judged to be basically reasonable and 19 cases(17.59％)were judged to be unreasonable.The main unreasonable problems were manifested in indications,the timing of administration,drug course and monitoring of efficacy and laboratory parameters.Conclusion The method of DUE of ozagrel sodium based on weighted TOPSIS is more comprehensively and intuitively.The application of ozagrel sodium in the hospital is relatively standardized,but there are problems in the course of medication,indications,and timing of administration.So it is necessary to promote the rational use by strengthening the cooperation between pharmacists and physicians,and improving pharmaceutical intervention.

Objective:To evaluate the effect of lower limb neuromuscular electrical stimulation (NMES) on mechanical ventilation patients in intensive care unit (ICU).Methods:Databases including the Cochrane Library, PubMed, Web of Science, Embase, SinoMed, CNKI, VIP and Wanfang database were searched from inception to May 2021. Randomized controlled trails (RCT) about the influence of NMES of lower limbs in patients with mechanical ventilation in ICU were collected. Routine rehabilitation measures were implemented in the control group, while the combination of routine rehabilitation and NMES on the lower limbs was implemented in the observation group. The literature screening, data extracting, and bias risk assessment of included studies were conducted independently by two reviewers. RevMan 5.3 software was used to perform Meta-analysis. Funnel plot was used to test publication bias.Results:A total of 8 RCT were eventually enrolled. The literature quality evaluation results showed that 1 study was grade A and 7 studies were grade B, suggesting that the quality of the included literature was relatively high. The Meta-analysis results showed that NMES in the lower extremities could effectively shorten the duration of mechanical ventilation in ICU patients [standardized mean difference ( SMD) = -0.51, 95% confidence interval (95% CI) was -0.72 to -0.31, P < 0.000 01], increase the maximum inspiratory pressure [MIP; mean difference ( MD) = 14.19, 95% CI was 9.30 to 19.09, P < 0.000 01], and improve the functional status of critically ill patients [functional status score for ICU (FSS-ICU); MD = 10.44, 95% CI was 3.12 to 17.77, P = 0.005] with statistically significances. However, there were no significant advantages in increasing the Medical Research Council (MRC) score ( MD = 2.13, 95% CI was -1.38 to 5.63, P = 0.23), reducing ICU mortality [relative risk ( RR) = 0.80, 95% CI was 0.51 to 1.24, P = 0.31], shortening length of ICU stay ( MD = -0.54, 95% CI was -3.67 to 2.59, P = 0.74), and the combined effect was not statistically significant. Funnel plot based on the duration of mechanical ventilation showed that the distribution of included articles was basically symmetrical, and no publication bias was detected. Conclusions:NMES of the lower limbs can not only shorten the ventilation duration effectively, but also improve the MIP and functional status of mechanically ventilated patients in ICU. However, it has no significant effect on the MRC score, ICU mortality and length of ICU stay of patients with mechanical ventilation. In the future, high-quality, large sample size and multi-center RCT are needed to verify the effects of NMES.

Objective To explore the effect of different hemostatic methods on ovarian function in la-paroscopic ovarian endometriosis cyst enucleation. Methods 200 cases of stage I and II ovarian endometriosis cyst admitted to our hospital from Jan. 2012 to Apr. 2014 were selected. All patients underwent conventional la-paroscopic ovarian endometrial endometriosis cyst enucleation. According to intraoperative hemostasis methods, patients were divided into 3 groups: suture group (n=70), electric coagulation group (n=70), and ultrasonic scalpel group (n=60). Follicle-stimulating hormone (FSH) and antibody forming cells (AFC) on admission and at 1, 3, 6, and 12 months after surgery were recorded. Peak systolic blood flow of ovarian stromal artery (PSV) was also observed. Results FSH for all the three groups were improved compared with that on admission, and the difference had statistical significance (P<0.05). FSH for the suture group was significantly lower than that in the electric coagulation group and ultrasound knife group at 1, 3, 6, and 12 months after operation. The difference had statistical significance (P<0.05). AFC at one month after surgery had no statistical significance between the 3 groups (P>0.05). however, AFC of the suture group at 3, 6, and 12 months after surgery was significantly im-proved compared with those of the the electric coagulation group and ultrasound knife group. The difference had statistical significance (P<0.05). Vaginal type B ultrasonic examination after operation showed that PSV of the su-ture group was higher than that of the electric coagulation group and ultrasound knife group at the second menstru-ation and at the 6-month menstruation after surgery. The difference of PSV between the 3 groups had statistical significance (P<0.05). Conclusion Compared electric coagulation hemostasis and ultrasonic scalpel hemostasis, the suture method can reduce damage of ovarian function in patients with ovarian endometriosis cyst, which is worth to promote.
