Objective To examine the association between epidemiological characteristics of hemorrhagic fever with renal syndrome (HFRS) and meteorological factors in Shenzhen City during the period from 2012 to 2019. Methods Average atmospheric pressure, average air temperature, average relative humidity, precipitation, wind speed, and sunshine duration were captured from Meteorological Bureau of Shenzhen City each month from 2012 to 2019. The average monthly rodent densities in Shenzhen City from 2012 to 2019 were acquired from the Vector Surveillance Management System of Guangdong Provincial Center for Disease Control and Prevention, and the monthly HFRS incidence was retrieved from Shenzhen Municipal Disease Surveillance System from 2012 to 2019. The correlation between meteorological factors and the monthly incidence of HFRS was examined us ing Spearman’s rank correlation in Shenzhen City, and the temporal trends in monthly HFRS incidence and the degrees of freedom for the rodent density were determined in Shenzhen City with a generalized additive model. The optimal lag time was identified using excess risk (ER) and its 95% confidence interval (CI), and univariate and multivariate models were fitted to evaluate the impact of meteorological factors on HFRS incidence in Shenzhen City. Results The median number of incident HFRS cases was 3.00 (interquartile range, 3.25) in Shenzhen City from 2012 to 2019, with an average air temperature of (23.44 ± 4.91) °C, average relative humidity of (76.05 ± 7.61)%, median precipitation of 4.10 (interquartile range, 6.83) mm, average wind speed of (1.97 ± 0.26) m/s, average sunshine duration of (5.17 ± 1.64) h, and median monthly rodent density of 1.74% (interquartile range, 2.52%). Spearman’s rank correlation analysis showed that the average air temperature positively correlated with average relative humidity (r_s = 0.420, P < 0.05), precipitation (r_s = 0.658, P < 0.05) and sunshine duration (r_s = 0.633, P < 0.05), and the atmospheric pressure negatively correlated with average air temperature (r_s = −0.925, P < 0.05), relative humidity (r_s = −0.614, P < 0.05), precipitation (r_s = −0.789, P < 0.05) and sunshine duration (r_s = −0.437, P < 0.05), while the average relative humidity correlated positively with precipitation (r_s = 0.724, P < 0.05) and negatively with sunshine duration (r_s = −0.218, P < 0.05). Univariate modeling analysis showed that the ERs and their 95% CI were 0.639% (0.540%, 0.737%) for average atmospheric pressure, −7.157% (−8.113%, −6.190%) for average air temperature, −3.603% (−4.219%, −2.985%) for average relative humidity, −5.889% (−7.085%, −4.669%) forprecipitation,21.881% (−5.149%, 56.612%) for average wind speed, and −13.877% (−16.641%, −11.022%) for sunshine duation (all P values < 0.05). Multivariate modeling analysis showed that in the ensemble model combining average atmospheric pressure and precipitation, the highest ER (6.686%) was caused by increased average atmospheric pressure, and the highest absolute ER values for average air temperature (6.615%), average relative humidity (3.107%) and precipitation (5.386%) were seen after adjustment only for sunshine duration (all P values < 0.05), while the highest absolute ER for sunshine duration (11.875%) was found after adjustment for precipitation (P < 0.05). Conclusions An increase in average air temperature, relative humidity, precipitation and sunshine duration resulted in a reduced incidence rate of HFRS in Shenzhen City from 2012 to 2019, and an increase in average atmospheric pressure increased the incidence of HFRS. Meteorological factors are important determinants affecting HFRS incidence in Shenzhen City.

Objective To explore the relationship between corrected QT interval(QTc)and short-term mortality rate in patients with cirrhotic ascites and the predictive value of QTc combined with Child-Pugh class for short-term death.Methods Patients hospitalized with cirrhotic ascites from October 2022 to March 2024 were selected as study subjects(training set,n=245),and similar patients from April to October 2024 were included for external validation(validation set,n=88).Patients'demographic data,basic clinical data,and first electrocardiography related indicators on admission were collected.Patients were divided into a death group and a survival group according to the 30-day follow-up result.The influencing factors for prognosis were explored by Lasso regression and univariate and multivariate binary logistic regression.A death risk nomogram model was constructed and evaluated by receiver operating characteristic curve(ROC curve),calibration curve,and decision curve.Data were analyzed for normality using Shapiro-Wilk test.Pairwise comparison for continuous data that were normally distributed was conducted by the independent-samples t test.Pairwise comparison for continuous data that were not normally distributed was conducted by the Mann-Whitney U test.Pairwise comparison for categorical data was performed using the chi-square test.Results The mortality rates were 35.1%(86/245)in the training set and 30.7%(27/88)in the validation set.Lasso regression showed that combined tumor,QTc,hematocrit,total bilirubin(TBil),direct bilirubin,alkaline phosphatase,albumin,cholinesterase,high-density lipoprotein cholesterol,carcinoembryonic antigen,international normalized ratio,model for end-stage liver disease(MELD),and Child-Pugh class were potential influencing factors for 30-day death in patients with cirrhotic ascites.Univariate and multivariate logistic regression showed that QTc(odds ratio[OR]=1.010,95%confidence interval[CI]:1.001-1.020,P=0.039),presence of tumor(OR=6.904,95%CI:2.997-12.391,P<0.001),TBil(OR=1.009,95%CI:1.004-1.014,P=0.001),and Child-Pugh class(OR=2.532,95%CI:1.256-5.105,P=0.009)were independent risk factors for 30-day death in patients with cirrhotic ascites.For the nomogram model constructed based on the results of the multivariate logistic analysis,the area under the ROC curve in the training set was 0.824;the sensitivity and specificity were 81.1%and 74.4%,respectively;the Hosmer-Lemeshow goodness-of-fit test showed P=0.673;the mean absolute error of the calibration curve was 0.020.The area under the ROC curve in the validation set was 0.886;the sensitivity and specificity were 91.8%and 70.4%,respectively;the Hosmer-Lemeshow goodness-of-fit test showed P=0.965;the mean absolute error of the calibration curve was 0.032.With the threshold probability of 0.15 to 0.85,the decision curve suggested a good benefit.The area under the ROC curve of the predictive model(0.824)was greater than conventional MELD score(0.700),MELD-Na score(0.698),and Child-Pugh score(0.674)(all P<0.05).Conclusion QTc is an independent predictor of short-term death in patients with cirrhotic ascites,and the prognostic model including QTc and Child-Pugh class has a good predictive value for short-term mortality rate.

Objective:To investigate the prevalence and determinants of dry eye syndrome among civil aviation flight attendants.Methods:Data from 1 201 civil aviation flight attendants across 6 airlines, along with their eye examination and general health records from the previous year, were collected and analyzed between January and March 2024. A self-designed questionnaire was designed to assess risk factors to dry eye syndrome. The severity of dry eye syndrome of these civil aviation flight attendants was assessed using the Ocular Surface Disease Index (OSDI) scale before they were grouped based on OSDI scores. The Fatigue Assessment Scale and Pittsburgh Sleep Quality Index were used to evaluate levels of fatigue and sleep quality. Multivariable Logistic regression was employed to identify factors associated with the severity of dry eye syndrome.Results:A total of 1 201 flight attendants were enrolled in this study. Questionnaires were distributed to all the participants, and 1 021 valid responses were collected, yielding a response rate of 85.0%. All flight attendants experienced dry eye syndrome. Among these cases, 657 cases were classified as moderate and 364 as severe. Logistic regression analysis showed that flying hours in the previous year ( OR=1.001, 95% CI: 1.001-1.002), a history of eyelid disease ( OR=2.059, 95% CI: 1.311-3.232), fatigue ( OR=2.438, 95% CI: 1.633-3.640), use of preservative-containing eye drops ( OR=3.034, 95% CI: 1.800-5.113), use of artificial tears ( OR=2.431, 95% CI: 1.544-3.827), use of contact lenses ( OR=2.095, 95% CI: 1.381-3.179), refractive progression of <-0.50 D ( OR=3.102, 95% CI: 1.955-4.920) and -0.50 to <-1.00 D ( OR=3.846, 95% CI: 1.845-8.018), sleep scale scores of 6-10 ( OR=1.940, 95% CI: 1.258-2.993), 11-15 ( OR=2.730, 95% CI: 1.564-4.768), and 16-21 ( OR=6.010, 95% CI: 1.752-20.614) were determinants of the severity of dry eye syndrome. Conclusions:Dry eye symptoms are generally severe among civil aviation flight attendants. Priority should be given to monitoring sleep quality and fatigue levels, with particular emphasis on individuals exceeding 713 flying hours in the previous year for early detection of dry eye syndrome.

Objective To investigate the risk factors for cardiovascular disease(CVD)in patients with rheumatoid arthritis(RA).Methods Clinical data of 225 patients with RA admitted to the Second Affiliated Hospital of Zhengzhou University from January 2023 to September 2024 were collected,and the patients were divided into CVD group(n=50)and non-CVD group(n=175)according to whether they were complicated by CVD.Univariate and multivariate Logistic regression was used to analyze the risk factors of CVD in RA patients.Results Univariate Logistic regression analysis showed that age,hematocrit,red cell volume distribution width(RDW),erythrocyte sedimentation rate,neutrophil to high density lipoprotein ratio(NHR)and platelet to lymphocyte ratio(PLR)were all influencing factors for CVD in RA patients(P＜0.05).Multivariate Logistic regression analysis showed that age,RDW,NHR and PLR were all risk factors for CVD in RA patients(P＜0.05).The results of receiver operating characteristic curve analysis showed that the area under the curve(AUC)of age,RDW,NHR and PLR diagnosed CVD in RA patients were 0.844,0.797,0.572 and 0.713,respectively.The combined diagnosis AUC of four indexes was 0.898.Conclusion The risk of CVD in RA patients is influenced by many factors,and the combination of age,RDW,NHR,and PLR can improve early diagnosis of CVD in RA patients.

Objective:To investigate the effects of thioredoxin reductase 1 (TXNRD1) on ferroptosis and immune function of dendritic cells (DCs) in septic mice, and to provide a basis for improving the immunosuppression in sepsis caused by wound infection.Methods:This study was an experimental research. Sixty male C57BL/6J mice aged 6-8 weeks were subjected to cecal ligation and puncture (CLP) to establish sepsis models. Ten mice were selected at 0 (immediately), 6, 12, 24, 48, and 72 h after CLP surgery, respectively, according to the random number table method. Mouse splenic DCs were isolated using CD11c-positive magnetic beads. The protein expressions of TXNRD1, and anti-ferroptosis proteins solute carrier family 7 member 11 (SLC7A11), and glutathione peroxidase 4 (GPX4) in the cells were detected by Western blotting, the reduced glutathione (GSH) content in the cells was measured by colorimetric assay, the lipid peroxidation level was assessed via live-cell imaging technology, and the levels of major histocompatibility complex class Ⅱ subtype I-A/I-E and leukocyte differentiation antigens CD80 and CD86 were detected by flow cytometry. Another 100 male C57BL/6J mice aged 6-8 weeks were divided into corn oil+sham injury group, corn oil+CLP group, inhibitor+sham injury group, and inhibitor+CLP group according to the random number table method, with 25 mice in each group. Mice in the two inhibitor groups were intraperitoneally injected with TXNRD1 inhibitor auranofin, while mice in the two corn oil groups were intraperitoneally injected with corn oil. One hour later, mice in the two CLP groups underwent CLP surgery to establish sepsis models, while mice in the two sham injury groups underwent sham surgery. Twenty mice from each group were selected to observe survival within 7 d post-surgery, and the survival rate was calculated. At 24 h post-surgery, mouse splenic DCs from the remaining 5 mice in each group were collected for corresponding assays as above.Results:Compared with those at 0 h after CLP surgery, the protein expressions of TXNRD1, GPX4, and SLC7A11 in mouse cells at 24 h after CLP surgery and the protein expression of TXNRD1 in mouse cells at 48 h after CLP surgery were significantly decreased ( P<0.05), the GSH content in mouse cells was significantly decreased at 24 and 48 h after CLP surgery ( P<0.05). The lipid peroxidation level in mouse cells was low at 0, 6, and 12 h after CLP surgery, slightly lower than that at 72 h after CLP surgery; the lipid peroxidation levels in mouse cells at 24 and 48 h after CLP surgery were significantly higher than those at 0, 6, 12, and 72 h after CLP surgery. Compared with those at 0 h after CLP surgery, the levels of I-A/I-E and CD80 in mouse cells at 6, 12, 24, 48, and 72 h after CLP surgery and the levels of CD86 in mouse cells at 12, 24, and 48 h after CLP surgery were significantly increased ( P<0.05). At 24 h post-surgery, the protein expressions of TXNRD1, SLC7A11, and GPX4 in mouse cells in corn oil+CLP group were significantly lower than those in corn oil+sham injury group ( P<0.05), while the protein expressions of TXNRD1, SLC7A11, and GPX4 in mouse cells in inhibitor+CLP group were significantly lower than those in corn oil+CLP group and inhibitor+sham injury group ( P<0.05). At 24 h post-surgery, the content of GSH in mouse cells in corn oil+CLP group was (239±32) μg/mg, which was significantly lower than (366±59) μg/mg in corn oil +sham injury group ( P<0.05); the content of GSH in mouse cells in inhibitor+CLP group was (134±19) μg/mg, which was significantly lower than (355±31) μg/mg in inhibitor+sham injury group and that in corn oil+CLP group (with both P values <0.05). At 24 h post-surgery, the lipid peroxidation level of mouse cells in inhibitor+CLP group was significantly higher than that in the other three groups ( P<0.05). At 24 h post-surgery, the levels of I-A/I-E, CD80, and CD86 in mouse cells in corn oil+CLP group were significantly higher than those in corn oil+sham injury group ( P<0.05), while the levels of I-A/I-E and CD80 in mouse cells in inhibitor+CLP group were significantly higher than those in inhibitor+sham injury group ( P<0.05) but significantly lower than those in corn oil+CLP group ( P<0.05); the level of CD86 in mouse cells in inhibitor+sham injury group was significantly higher than that in corn oil+sham injury group ( P<0.05). Within 7 d post-surgery, the survival rate of mice in inhibitor+CLP group was significantly lower than that in inhibitor+sham injury group and corn oil+CLP group (with χ2 values of 31.19 and 3.91, respectively, both P values <0.05). Conclusions:In septic mice, the expression of TXNRD1 in DCs is reduced, cell ferroptosis is enhanced, and immune function is weakened. The inhibition of TXNRD1 in DCs will exacerbate cell ferroptosis and immune function suppression, and is closely related to the poor prognosis of sepsis.

Objective:To investigate the effects of Xuebijing injection on gut microbiota and intestinal mechanical barrier in mice with lipopolysaccharide (LPS)-induced sepsis, and analyze the potential mechanism by which Xuebijing injection protects gastrointestinal tract.Methods:Twenty-four healthy and clean grade male C57BL/6N mice were divided into four groups, control group, LPS group, LPS+ 5 μl/g Xuebijing injection group (5 μl/g Xuebijing injection group), and LPS+ 10 μl/g Xuebijing injection group (10 μl/g Xuebijing injection group), with six mice in each group. A mouse model of sepsis was established by intraperitoneal injection of mice with 10 μg/g LPS. At 0 and 12 h after successful modeling, the mice were intraperitoneally injected with 5 or 10 μl/g Xuebijing injection. Blood, ileum, and colon fecal samples were collected 12 h after the second administration. ELISA was used to detect the levels of diamine oxidase (DAO), D-blood lactic acid (D-Lac), TNF-α, and IL-6. HE staining was used to observe the local ileum damage, and Chiu′s score was used to evaluate the degree of intestinal tissue damage. Immunohistochemical staining and Western blot were used to detect the expression of Claudin-1, Occludin, and zona occludins-1(ZO-1) in ileum tissues, followed by semi quantitative analysis. One-way analysis of variance was used for intergroup comparisons, and LSD or Tamhane′s T2 test was used for pairwise comparisons based on the homogeneity of variance. The diversity and species composition of mouse fecal microbiota, and the differences among groups were analyzed using 16S rRNA sequencing.Results:The levels of DAO, D-Lac, TNF-α, and IL-6 in the LPS group were higher than those in the control group (all P<0.000 1). After the intervention with Xuebijing injection, the levels of DAO, D-Lac, TNF-α, and IL-6 decreased (all P<0.05) and showed no significant differences with those in the control group (all P>0.05). Besides, 10 μl/g Xuebijing injection was more effective than 5 μl/g Xuebijing injection in reducing the concentrations (all P<0.05). Chiu′s score was higher in the LPS group than in the control group and the 10 μl/g Xuebijing injection group (both P<0.05). Western blot showed that the expression levels of Occludin, Claudin-1, and ZO-1 in the LPS group were lower than those in the control group (all P<0.01), and Xuebijing injection intervention significantly increased the expression levels of these proteins in a dose-dependent manner as compared with the LPS group (all P<0.000 1). Apart from the expression level of ZO-1, which showed no significant difference between the two Xuebijing injection groups ( P>0.05), the results of immunohistochemical staining were consistent with those of Western blot. The 16S rRNA sequencing results showed that there were differences in the Alpha and Beta diversity indices, and the composition and structure of gut microbiota among the four groups. The structure of gut microbiota in the mice treated with Xuebijing injection was similar to that in the mice of the control group and it was in a dose-dependent manner. Wilcoxon rank sum test showed that there were statistically significant differences in six gut microbiota groups at the phylum level, and 32 gut microbiota groups at the genus level among the mice of four groups (all P<0.05). Conclusions:Xuebijing injection can provide protective effects on the gastrointestinal tract by protecting the structure of gut microbiota and intestinal barrier function, and the protective effect is somewhat correlated with the drug dosage.

Objective:To characterize the vaginal flora of pregnant women during the second trimester using full-length 16S rRNA sequencing.Methods:A total of 142 pregnant women were systematically sampled from a pregnancy cohort. Vaginal swabs were collected for full-length 16S rRNA gene sequencing，and bioinformatics analysis was performed to characterize the vaginal microbiota and identify associated influencing factors.Results:Among the 142 pregnant women，the most frequently detected species were Lactobacillus iners（83.10%，118/142）and Lactobacillus crispatus（49.30%，70/142）. The majority of samples（90.85%，129/142）were classified as Lactobacillus-dominant vagitypes，with the Lactobacillus iners vagitype accounting for 48.59%（69/142）and the Lactobacillus crispatus vagitype accounting for 38.73%（55/142）. The vaginal microbiota was clustered into five community state types（CSTs）：Ⅰa，Ⅰb，Ⅲa，Ⅲb，and Ⅳ. The most prevalent CSTs were Lactobacillus iners-dominated CST-Ⅲ（51.41%，73/142）and Lactobacillus crispatus-dominated CST-Ⅰ（24.65%，35/142）. No samples were classified as CST-Ⅱ or CST-Ⅴ. A significant negative correlation was observed between Lactobacill and vaginosis-associated bacteria. Age，alcohol consumption，smoking，and vaginal treatments showed significant associations or trends toward significance with various Alpha diversity indices. Vaginal douching was associated with CST clustering，while obstetric history（primiparity，previous miscarriage history）was associated with vagitype classification. However，no significant associations were identified between maternal baseline characteristics and Beta diversity indices. Conclusions:Full-length 16S rRNA gene sequencing reveals that the vaginal microbiota of pregnant women is dominated by Lactobacillus iners and Lactobacillus crispatus. Maternal age，lifestyle factors such as smoking and alcohol consumption，and obstetric history are significantly associated with variations in vaginal microbiota composition.

Objective:To analyze the trends of preterm birth among women of advanced maternal age in Haidian District, Beijing from 2013 to 2022.Methods:A retrospective analysis was conducted on the birth registration data in Haidian District, Beijing, from January 2013 to December 2022, focusing on the records of women aged ≥35 who delivered between 22 and 44 weeks of gestation. The Joinpoint regression model was used to analyze the time trends of preterm birth rates among women of advanced maternal age in the Haidian District. Interrupted time series (ITS) analysis was applied to quantitatively evaluate the transient and long-term effects of China's universal two-child policy on the preterm birth rate among women of advanced maternal age.Results:(1) A total of 70 640 birth registration records from 68 587 women were finally included. The number of women giving birth peaked between 2016 and 2018 (8 158, 9 906, and 8 914 cases, respectively). The proportion of permanent residents in Beijing gradually decreased from 53.7% (2 175/4 049) in 2013 to 42.0% (4 160/9 906) in 2017 and then increased to over 98% between 2019 and 2022 [98.8% (7 828/7 925), 99.1% (6 283/6 340), 99.3% (5 970/6 014), and 99.5% (6 371/6 404), respectively]. (2) Among the 68 587 women, 57 339 (83.6%) were delivered at tertiary hospitals, and 35 496 (51.8%) were delivered by cesarean section. The proportion of multiple births increased slowly from 2.4% (236/9 906) in 2017 to 3.5% (225/6 404) in 2022. From 2013 to 2015, primiparous women accounted for the majority. Subsequently, the proportion of multiparous women increased annually, reaching 71.6% (6 385/8 914) in 2018 before gradually decreasing to 56.2% (3 600/6 404) in 2022. (3) A total of 70 640 live births were delivered. The highest number of deliveries was in 2017, with 10 139 cases. From 2013 to 2022, 36 995 male infants and 33 645 female infants were born, with preterm birth rates of 10.6% (3 914/36 995) and 9.4% (3 123/33 645), respectively. (4) Among the 70 640 infants, there were 124 extremely preterm infants (0.2%), 773 very preterm infants (1.1%), and 6 140 late preterm infants (8.7%), accounting for 1.8%, 11.0%, and 87.3% of all preterm infants (7 037 cases), respectively. (5) The optimal fitting results of Joinpoint regression indicated that the preterm birth rate showed a declining trend from 2013 to 2017 ( APC=－4.4%, 95% CI: -13.0% to -0.2%); with 2017 as the turning point, the preterm birth rate exhibited an upward trend from 2017 to 2022 ( APC=4.5%, 95% CI: 1.6% to 13.0%). (6) The results of ITS analysis revealed that the preterm birth rate instantly decreased by 0.79% ( β2=－0.79, P=0.026) in the month when the universal two-child policy took effect. In comparison, it increased by an average of 0.03% per month ( β3=0.07, P=0.001) after the implementation of the policy. After adjusting for the proportion of multiple births, the preterm birth rate significantly decreased before the policy took effect ( β1=－0.06, P=0.003), but increased by an average of 0.01% per month ( β3=0.07, P<0.001) after the policy took effect. There was no statistical significance in the transient impact of the policy on the preterm birth rate in this district ( β2=0.80, P=0.145). Conclusions:From 2013 to 2022, the preterm birth rates among women of advanced maternal age in Haidian District exhibit a "V"-shaped pattern with the implementation of the two-child policy as the turning point. It is necessary to continue strengthening maternal health care for women of advanced maternal age and ensure the targeted provision of related services to address the issue of increased preterm birth rates following the enforcement of the two-child policy.

Objective:To establish and assess the quality control and improvement system for metabolic and bariatric surgery in Beijing.Methods:Based on relevant documents from the National Health Commission and the Beijing Municipal Health Commission,and referencing the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) by the American Society for Metabolic and Bariatric Surgery,a quality control system was developed under the Beijing Quality Control and Improvement Center of Metabolic and Bariatric Surgery. The system incorporated on-site evaluations,data registration,and specialized training. From May to December 2023,on-site assessments were conducted at 21 hospitals in Beijing performing bariatric surgery,evaluating personnel qualifications,infrastructure,clinical workflows,and postoperative follow-up. A quality control database was created to collect real-time surgical data,and training was provided for data entry and professional skills. Assessment results were classified as excellent,qualified,or needing improvement,with rectification suggestions offered and follow-up visits conducted to track progress.Results:All 21 hospitals achieved a 100% compliance rate for surgical indications, 16 (76.2%) met standardized surgical operation criteria,and 14 (66.7%) had standardized postoperative management. However,only 5 (23.8%) achieved a 12-month postoperative follow-up rate of ≥60%,and 4 (19.1%) had established specialized databases. Key challenges included insufficient specialized staffing (19.1%), lack of multidisciplinary collaboration (47.6%), inadequate equipment (57.1%), and low follow-up rates (57.1%). The database collected data from over 2 000 patients across 111 fields. After rectification, specialized database coverage rose to 61.9% (13 hospitals). Multi-level training programs developed backbone physicians and specialized nurses,significantly addressing the shortage of specialized personnel.Conclusion:The quality control system established in this study,through the integration of on-site evaluation,data registration,and specialized training,effectively enhances the standardization of surgical practices and data management capabilities.
