OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of serplulimab as a first-line treatment of small- cell lung cancer （SCLC）， and provide an evidence-based basis for drug selection in hospitals. METHODS Rapid health technology assessment was adopted； PubMed， Cochrane Library， Embase， CNKI， Wanfang， VIP and official websites of domestic and international health technology assessment agencies were systematically searched from the inception to Oct. 2024. Two reviewers independently screened the literature， assessed the quality of included studies and carried out the qualitative analysis according to the inclusion and exclusion criteria. RESULTS A total of 13 systematic reviews/meta-analyses and 9 economic studies were included， and the literature quality was generally good. In terms of effectiveness， compared with chemotherapy alone， serplulimab combined with chemotherapy significantly improved progression-free survival， overall survival， and objective response rate in patients with SCLC. In terms of safety， serplulimab combined with chemotherapy showed no significant difference in the incidence of ≥3 grade adverse events compared with chemotherapy alone in the treatment of SCLC， indicating a good safety profile； compared with combination therapies involving other immunosuppressive agents， the incidence rate of adverse events was also lower. In terms of cost-effectiveness， compared with chemotherapy alone， serplulimab combined with chemotherapy is not cost- effective， which may be related to the high price of serplulimab. CONCLUSIONS Serplulimab is effective and safe in the treatment of SCLC， but has no obvious advantage in terms of cost-effectiveness.

Objective:To analyze the concentration of formic acid,propionic acid and butyric acid in gingival crevicular fluid(GCF)of patients with stages Ⅲ and Ⅳ periodontitis,and their relationship with periodontitis.Methods:The study enrolled 37 systemically healthy patients with periodontitis and 19 healthy controls who visited Department of Periodontology,Peking University School and Hospital of Sto-matology from February 2008 to May 2011.Their GCFs were collected from the mesial-buccal site of one molar or incisor in each quadrant.Periodontal clinical parameters,including plaque index(PLI),probing depth(PD),bleeding index(BI),and attachment loss(AL).Concentrations of formic acid,propionic acid and butyric acid in the supernatant of the GCFs were analyzed by high-performance capil-lary electrophoresis(HPCE).The prediction ability of formic acid,propionic acid and butyric acid with the risk of periodontitis and the differences between grade B and grade C periodontitis were analyzed.Results:In this study,32 patients with stage Ⅲ and 5 patients with stage Ⅳ were enrolled,including 9 patients with grade B and 28 patients with grade C.Clinical periodontal variables in the patients with pe-riodontitis were significantly higher than those in the control group(P＜0.001).Formic acid was signifi-cantly lower in periodontitis than that in the control group[5.37(3.39,8.49)mmol/L vs.12.29(8.35,16.57)mmol/L,P＜0.001].Propionic acid and butyric acid in periodontitis were significantly higher than those in the control group:Propionic acid,10.23(4.28,14.90)mmol/L vs.2.71(0.00,4.25)mmol/L,P＜0.001;butyric acid,2.63(0.47,3.81)mmol/L vs.0.00(0.00,0.24)mmol/L,P＜0.001.There was no significant difference in formic acid,propionic acid and butyric acid concentrations between grade B and grade C periodontitis(P＞0.05).Propionic acid and butyric acid in the deep pocket were significantly higher than in the shallow pocket,while the concentration of formic acid decreased with the increase of PD.Propionic acid(OR=1.51,95％CI:1.29-1.75)and butyric acid(OR=3.72,95％CI:1.93-7.17)were risk factors for periodontitis,while formic acid(OR=0.87,95％CI:0.81-0.93)might be a protective factor for periodontitis.Propionic acid(AUC=0.852,95％CI:0.805-0.900),butyric acid(AUC=0.889,95％CI:0.841-0.937),f(formic acid,AUC=0.844,95％CI:0.793-0.895)demonstrated a good predictive capacity for the risk of periodontitis.Conclusion:The concentration of formic acid decrease in the GCF of periodontitis patients,which is a protective factor for periodontitis,its reciprocal have good predictive capacity.However,propionic acid and butyric acid increase,which are risk factors for periodontitis and have good predictive capacity.The concentration of formic acid,propionic acid,and butyric acid vary with probing depth,but there is no significant difference between grade B and grade C periodontitis.

Objective:This study aims to obtain the prevalence and features associated with Violence Against Children (VAC) in China and, thus, formulate a prevention strategy.Methods:The mortality-related data of VAC was sourced from the National Disease Surveillance Points System (DSP) during 2013-2021. We analyzed the DSP data regarding children aged 0-17 years old who died from violence. The hospital cases of VAC was sourced from the National Injury Surveillance System (NISS), 2013-2021. We analyzed the data from NISS with the parameter of "intentional injury" caused by VAC in children aged between 0-17 years. Using robust linear regression, we analyze the time trend in the proportion of violence incidence. To understand the variations in the incidence of different types of violence across genders, we apply the chi-square test and adjusted Pearson residuals.Results:The overall trend of death caused by VAC has declined; it was reduced to 0.14/100 000 in 2021 from 0.33/100 000 in 2013. In 2021, male VAC mortality (0.15/100 000) was higher than females (0.13/100 000). The proportion of VAC cases to all injury cases has declined from 3.34% in 2013 to 2.29% in 2021. Among 9 344 VAC cases supervised by hospitals in 2021, the number of males (7 503 cases) was around 4 times that of females (1 841 cases), and the top three modes of violence were blunt tools (64.77%), falls (7.46%) and sharp instruments (6.18%), and 45 cases of sexual violence included 38 girls and 7 boys.Conclusions:The declining death rate due to VAC may be related to the benign development of Chinese society. Prevention strategies targeting training in parenting skills and problem-solving should be prioritized.

Objective:To construct a nomogram model for predicting stress urinary incontinence (SUI) in young and middle-aged women.Methods:Using a sampling survey method, 1 000 questionnaires were distributed to young and middle-aged women in 2 streets of Urumqi community from May 2021 to October 2023 to investigate their basic situation, lifestyle habits and gynecological related information. The International Urinary Incontinence Advisory Committee urinary incontinence questionnaire was used to diagnose SUI, and the patients were divided into SUI group and control group based on the results. Seven hundred and eighty-six questionnaires were collected. The survey results of the two groups were analyzed, and a nomogram model for predicting the occurrence of SUI in young and middle-aged women was constructed and validated.Results:Among the 786 young and middle-aged women, there were 147 cases in the SUI group and 639 cases in the control group. The age, body mass index (BMI), and the incidences of diabetes, chronic constipation, delivery history, macrosomia delivery history, pelvic floor dysfunction in SUI group were significantly higher than those in control group: (44.51 ± 8.20) years vs. (38.60 ± 12.35) years, (27.31 ± 4.53) kg/m 2 vs. (24.28 ± 4.38) kg/m 2, 13.61% (20/147) vs. 3.44% (22/639), 19.05% (28/147) vs. 5.01% (32/639), 90.48% (133/147) vs. 75.90% (485/639), 17.01% (25/147) vs. 3.44% (22/639) and 11.56% (17/147) vs. 3.29% (21/639), and there were statistical differences ( P<0.01). Multivariate Logistic regression analysis result showed that age>44 years, BMI≥30 kg/m 2, diabetes, chronic constipation, delivery history, macrosomia delivery history and pelvic floor dysfunction were independent risk factors for SUI in young and middle-aged women ( RR = 1.511, 2.543, 4.636, 4.293, 2.526, 6.220 and 5.834; 95% CI 1.007 to 2.268, 1.661 to 3.894, 2.281 to 9.422, 2.339 to 7.881, 1.374 to 4.643, 3.205 to 12.071 and 2.641 to 12.888; P<0.05 or <0.01). The age, BMI, diabetes, chronic constipation, delivery history, macrosomia delivery history and pelvic floor dysfunction were used as predictors to construct a nomogram model for predicting the SUI in young and middle-aged women. The 550 cases were randomly selected from the dataset as the training set and the remaining 236 cases as the validation set. The receiver operating characteristic curve was drawn, and the result showed that the area under the training set curve was 0.818 (95% CI 0.773 to 0.862), and the area under the validation set curve was 0.826 (95% CI 0.764 to 0.889); the Hosmer-Lemeshow goodness of fit test in validation set that result showed that the nomogram model had high reliability ( χ2 = 8.48, P>0.05). Conclusions:The incidence of SUI in young and middle-aged women is high. The age >44 years, BMI≥30 kg/m 2, diabetes, chronic constipation, delivery history, macrosomia delivery history and pelvic floor dysfunction are independent risk factors for SUI in young and middle-aged women. The nomogram model based on related risk factors has high predictive value and credibility.

Objective:To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes.Methods:The clinical data of children with septic shock in children′s PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results:A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs ( OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions:The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Objective:To investigate the clinical features, pathogen composition, and prognosis of septic shock in pediatric intensive care units (PICU) in China.Methods:A multicenter retrospective cohort study. A retrospective analysis was conducted on the clinical data of children with septic shock from 10 hospitals in China between January 2018 and December 2021. The clinical features, pathogen composition, and outcomes were collected. Patients were categorized into malignant tumor and non-malignant tumor groups, as well as survival and mortality groups. T test, Mann Whitney U test or Chi square test were used respectively for comparing clinical characteristics and prognosis between 2 groups. Multiple Logistic regression was used to identify risk factors for mortality. Results:A total of 1 247 children with septic shock were included, with 748 males (59.9%) and the age of 3.1 (0.9, 8.8) years. The in-patient mortality rate was 23.2% (289 cases). The overall pathogen positive rate was 68.2% (851 cases), with 1 229 pathogens identified. Bacterial accounted for 61.4% (754 strains) and virus for 24.8% (305 strains). Among all bacterium, Gram negative bacteria constituted 64.2% (484 strains), with Pseudomonas aeruginosa and Enterobacter being the most common; Gram positive bacteria comprised 35.8% (270 strains), primarily Streptococcus and Staphylococcus species. Influenza virus (86 strains (28.2%)), Epstein-Barr virus (53 strains (17.4%)), and respiratory syncytial virus (46 strains (17.1%)) were the top three viruses. Children with malignant tumors were older and had higher pediatric risk of mortality (PRISM) Ⅲ score, paediatric sequential organ failure assessment (pSOFA) score (7.9 (4.3, 11.8) vs. 2.3 (0.8, 7.5) years old, 22 (16, 26) vs. 16 (10, 24) points, 10 (5, 14) vs. 8 (4, 12) points, Z=11.32, 0.87, 4.00, all P<0.05), and higher pathogen positive rate, and in-hospital mortality (77.7% (240/309) vs. 65.1% (611/938), 29.7% (92/309) vs. 21.0% (197/938), χ2=16.84, 10.04, both P<0.05) compared to the non-tumor group. In the death group, the score of PRISM Ⅲ, pSOFA (16 (22, 29) vs. 14 (10, 20) points, 8 (12, 15) vs. 6 (3, 9) points, Z=4.92, 11.88, both P<0.05) were all higher, and presence of neoplastic disease, positive rate of pathogen and proportion of invasive mechanical ventilation in death group were also all higher than those in survival group (29.7% (87/289) vs. 23.2% (222/958), 77.8% (225/289) vs. 65.4% (626/958), 73.7% (213/289) vs. 50.6% (485/958), χ2=5.72, 16.03, 49.98, all P<0.05). Multiple Logistic regression showed that PRISM Ⅲ, pSOFA, and malignant tumor were the independent risk factors for mortality ( OR=1.04, 1.09, 0.67, 95% CI 1.01-1.05, 1.04-1.12, 0.47-0.94, all P<0.05). Conclusions:Bacterial infection are predominant in pediatric septic shock, but viral infection are also significant. Children with malignancies are more severe and resource consumptive. The overall mortality rate for pediatric septic shock remains high, and mortality are associated with malignant tumor, PRISM Ⅲ and pSOFA scores.

Objective:To compare the efficacy of programmed death-1(PD-1)inhibitors combined with chemotherapy with that of bevaci-zumab combined with chemotherapy as first-line treatments for advanced non-squamous non-small cell lung cancer(nsNSCLC).Methods:Retrospective collection of 237 patients with advanced nsNSCLC who received first-line treatment at the Fourth Hospital of Hebei Medical University from November 2014 to March 2024.According to the treatment plan,119 cases were assigned into PD-1 inhibitor com-bined with chemotherapy(IC group)and 118 cases were assigned into bevacizumab combined with chemotherapy(BC group).Propensity score matching(PSM)was used to balance covariates.The primary endpoint was progression-free survival(PFS),and the secondary end-points were objective response rate(ORR),disease control rate(DCR),and overall survival(OS).Results:Among 237 patients with PSM,87 were assigned to the IC group and 87 to the BC group,with respective ORRs of 31.0%(27/87)and 43.7%(38/87)(P=0.085)and respective DCRs of 96.6%(84/87)and 95.4%(83/87)(P=1.000).No significant difference in the median PFS was observed between the two groups,with a PFS value of 9.3 months in the IC group and 9.1 months in the BC group(P=0.053).In addition,the two groups also showed no significant difference in OS(neither group reached the median OS;P=0.116).Conclusions:There was no significant difference in the short-term efficacy between chemotherapy combined with PD-1 inhibitor and that combined with bevacizumab as first-line treatments for advanced nsNSCLC.

Objective:To understand the research ability, cognition, and training needs of clinical medical staff in a grade A tertiary hospital in Xinjiang and to analyze the influencing factors.Methods:A convenience sampling method was applied to survey the clinical medical staff of our hospital with a questionnaire including general information, a self-assessment scale of research ability, and a survey of research cognition and training needs. A total of 618 questionnaires were collected with 609 valid returned responses, resulting in an effective return rate of 98.54%. Univariate and multiple linear regression analysis were applied to analyze the influencing factors of the total score of clinical medical staff's research ability.Results:The total score of research ability of 609 clinical medical personnel was 60.73±13.59. The results of multiple linear regression showed that participation in scientific research conferences, enthusiasm for scientific research activities, and the need for scientific research training all had positive effects on the self-assessment of scientific research ability, which together explained 52% of the total variance (adjusted R2=0.520, P<0.001). The top three " very important" options for medical staff research training were data analysis, research design, and research topic selection. Conclusions:Medical staff research skills need to be improved and there is a strong need for research training. Managers should refine scientific research management initiatives and provide hierarchical and targeted scientific research training to improve the overall medical staff's scientific research literacy and research ability, thereby promoting the progress of medical care in hospitals.

Objective:To investigate the current situation of occurrence of social isolation in maintenance hemodialysis patients and analyze its influencing factors, in order to provide a theoretical basis for the implementation of targeted interventions.Methods:The study was a cross-sectional study. A total of 315 dialysis patients in three hemodialysis centers in Xinjiang were selected by simple sampling method from October 2021 to March 2022, who were investigated using the general information questionnaire, Lubben-6 social network scale, International Physical Activity Questionnaire (sedentary behavior section), Patient Health Questionnaire 9-item scale (PHQ-9) and Frail Scale. Univariate analysis and binary Logistic regression analysis were used to explore the influencing factors affecting the social isolation of dialysis patients.Results:Social isolation was present in 28.89% (91/315) of maintenance hemodialysis patients, and binary Logistic regression analysis revealed that age (45-59 years old: OR=4.815, 95% CI 1.362-17.017;≥60 years old: OR=8.968, 95% CI 2.349-34.236), dialysis age ( OR=2.788, 95% CI 1.334-5.826), sedentary behavior ( OR=2.504, 95% CI 1.406-4.461), depression ( OR=2.095, 95% CI 1.179-3.722), and debilitation ( OR=2.043, 95% CI=1.062-3.933) were influencing factors of social isolation in maintenance hemodialysis patients (all P<0.05). Conclusions:The occurrence of social isolation in maintenance hemodialysis patients was closely associated with advanced age, high dialysis age, sedentary behavior, debilitation, and depressive status, suggesting that medical staff in hemodialysis centers can implement targeted interventions to prevent or improve the level of social isolation in patients based on relevant influencing factors.
