ObjectiveTo investigate whether the effect of Taohong Siwutang on cerebral ischemia-reperfusion （CIRI） injury in rats is related to the regulation of astrocyte polarization and explore the related mechanism. MethodsEighty-four male SD rats were randomly assigned to the following groups： A sham operation group， a model group， Taohong Siwutang treatment groups （low dose， medium dose， and high dose）， ligustrazine phosphate tablet （LPT） group， and AG490 group. All groups， except for the sham operation group， underwent middle cerebral artery occlusion/reperfusion （MCAO/R） modeling and were treated for seven days. The neurological impairment was evaluated using the Longa score. The volume of cerebral infarction was assessed through 2，3，5-triphenyltetrazolium chloride （TTC） staining. Real-time fluorescent quantitative polymerase chain reaction （Real-time PCR） and Western blot analyses were performed to analyze the mRNA and protein expression levels of cortical complement 3 （C3）， S100 calcium-binding protein A10 （S100A10）， Janus kinase 2 （JAK2）， and signal transducer and activator of transcription 3 （STAT3）. Additionally， protein expression levels of vascular endothelial growth factor-A （VEGF-A） were assessed， and the mRNA expression levels of inflammatory factors， including interleukin-6 （IL-6）， interleukin-1β （IL-1β）， and tumor necrosis factor-α （TNF-α）， were evaluated. Glial fibrillary acidic protein （GFAP） and C3， S100A10 and Co-localization was detected via immunofluorescence double staining. Lastly， VEGF expression levels were measured using enzyme-linked immunosorbent assay （ELISA）. ResultsCompared with the sham operation group， the model group showed a significant increase in cerebral infarction volume and neurological impairment （P<0.01）. C3 protein levels were elevated， while S100A10 levels were decreased. Pathway-related markers were significantly upregulated （P<0.05， P<0.01）， and VEGF-A protein levels were significantly reduced （P<0.01）. The mRNA expression of inflammatory factors was significantly upregulated （P<0.01）. Co-localization analysis showed significantly increased GFAP and C3 fluorescence intensity （P<0.01） and greatly decreased GFAP and S100A10 fluorescence intensity （P<0.01）. Additionally， VEGF content was significantly elevated （P<0.01）. Compared with the model group， medium- and high-dose Taohong Siwutang and LPT groups exhibited a significant reduction in cerebral infarction volume and neurological impairment （P<0.01）. Groups treated with low， medium， and high doses of Taohong Siwutang and LPT group exhibited a decrease in C3 protein expression levels and an increase in S100A10 expression levels （P<0.01）. In the high-dose Taohong Siwutang and AG490 groups， both protein and mRNA expression of C3 and pathway-related markers were significantly downregulated （P<0.05， P<0.01）， while S100A10 expression and VEGF-A protein levels were significantly increased （P<0.01）. Additionally， the mRNA expression levels of inflammatory factors were significantly reduced （P<0.01）. The co-localization fluorescence intensity of GFAP and C3 significantly decreased （P<0.01）， while that of GFAP and S100A10 greatly increased （P<0.01）. Furthermore， VEGF content exhibited a marked elevation （P<0.01）. ConclusionTaohong Siwutang exerts a protective effect in rats with cerebral CIRI injury. The underlying mechanism is associated with the downregulation of the JAK2/STAT3 signaling pathway， promotion of A2-type astrocyte polarization， reduction of inflammatory factor release， and enhancement of VEGF production.

Objective:To explore the mediating effect of frailty between stress perception and kinesiophobia in elderly patients after temporary cardiac pacemaker implantation.Methods:A total of 129 elderly patients who underwent temporary cardiac pacemaker implantation surgery in the Department of Cardiovascular Medicine of the First Affiliated Hospital of Zhengzhou University from February 2023 to April 2024 were selected by convenience sampling method, and were surveyed by the general information questionnaire, the exercise fear scale, the perceived stress scale and the Chinese Tilburg frailty scale.The t test, one-way ANOVA and non parametric test were used to analyze the data by SPSS 29.0 software.The macro program PROCESS was used to construct and test the mediation model. Results:The total score of kinesiophobia was (41.08±2.77), the total score of stress perception was (36.22±3.07), and the total score of frailty was (11.19±1.53) in elderly patients after temporary cardiac pacemaker implantation. The total score of kinesiophobia was positively correlated with the total score of stress perception ( r=0.383, P<0.01), the total score of kinesiophobia was positively correlated with the total score of frailty ( r=0.451, P<0.01), and the total score of stress perception was positively correlated with the total score of frailty ( r=0.289, P<0.01).The total effect of stress perception on motor fear was 0.359 ( P<0.01) and the direct effect was 0.226 ( P<0.01).Frailty played a partial mediating role between stress perception and kinesiophbia in elderly patients after temporary pacemaker implantation, with an indirect effect of 0.133 (95% CI=0.062-0.243), accounting for 37.05% of the total effect. Conclusion:Stress perception not only directly affects kinesiophobia in elderly patients with temporary cardiac pacemaker implantation, but also indirectly affects kinesiophobia through frailty.

Objective:To conjecture the correlation between fetal hydrothorax(FHT)and pregnancy outcome through the analysis of 95 fetuses with hydrothorax and their mothers.Methods:In this case series study, 95 FHT patients admitted to the Third Affiliated Hospital of Zhengzhou University from January 2016 to October 2022 were retrospectively analyzed.According to the pregnancy outcome, these patients were divided into the induced labor group (13 patients) and the delivery group (82 patients). General data and genetic examinations of patients in the induced labor group were analyzed to explore their pathogenesis and genetics.According to the neonatal Apgar score, patients in the delivery group were divided into the normal group and the asphyxia group.Fifteen indicators including the maternal age, gestational week at first diagnosis, maternal complications, FHT location, FHT severity, FHT outcome during pregnancy, fetal ascites, hydrops fetalis, other abnormal fetal structures, amniotic fluid volume, intrauterine treatment, gestational week of delivery, mode of delivery, sex of the newborn, and newborn birth weight in the 2 groups were comparatively analyzed by the chi-square test.With the neonatal Apgar score as the dependent variable, variables that had statistical significance during the univariate analysis were included in the regression analysis, and a multivariate binary Logistic regression equation was established to explore the factors affecting the pregnancy outcome.Results:There were significant differences in the FHT outcome during pregnancy (16/22/13 cases vs.2/18/11 cases, χ2=6.994, P=0.030), FHT severity (27/24 cases vs.9/22 cases, χ2=4.475, P=0.034), hydrops fetalis (14/37 cases vs.23/8 cases, χ2=17.012, P=0.001), amniotic fluid volume (21/30 cases vs.24/7 cases, χ2=10.228, P=0.001), intrauterine treatment (19/32 cases vs.2/29 cases, χ2=9.603, P=0.002), gestational week of delivery[(38.15±2.05) weeks vs.(34.83±3.14) weeks, t=5.748, P=0.001], and newborn birth weight[(3 325.00±637.41) g vs.(2 714.58±837.99) g, t=3.727, P=0.001]between the normal and asphyxia groups(all P<0.05). Among them, hydrops fetalis ( OR=7.070, P=0.020) and severe FHT ( OR=6.927, P=0.043) were risk factors for neonatal Apgar scores.Intrauterine treatment ( OR=0.062, P=0.027) and gestational week of delivery( OR=0.577, P=0.022) could be used as a protective factor for neonatal Apgar scores. Conclusions:Diagnosis of FHT during the early gestational weeks and multiple fetal structural abnormalities, especially hydrops fetalis, have higher probabilities of abnormal genetic examinations, and the fetal prognosis was poor.It is recommended to carry out chromosomal karyo type and microarray tests, as well as whole exome sequencing and detection of genetic syndromes(if necessary), to avoid unnecessary fetal treatment and improve the survival rate of perinatal infants after intrauterine treatment.The poor prognosis is related to hydrops fetalis and severe FHT; however, timely intrauterine treatment and prolonging pregnancy can improve the pregnancy outcome and increase the survival rate of perinatal infants.

Objective:To explore the protective effect of methyl eugenol (Me) on islet ischemia/reperfusion (I/R) injury and elucidate its underlying mechanism.Methods:The islets were isolated and purified from 6-8 week male BALB/c mice and divided into four groups of normal control (normal culture without any treatment), hypoxia/reoxygenation (H/R treatment), H/R+ dimethyl sulfoxide (DMSO dosing plus H/R treatment) and H/R+ Me (Me dosing plus H/R). Viability of islet cells in each group was detected by acridine orange (AO)/propidium iodide (PI) double stain.Function of islet cells (insulin secretion) was measured by enzyme-linked immunosorbent assay (ELISA). Murine islet β Min6 cells were selected for detecting the effect of Me on the proliferative activity of normal cultured and H/R treated islet cells under different concentration gradients by CCK8.Then Min6 cells were divided into four groups of normal, H/R, H/R+ DMSO and H/R+ Me.The definition of group was the same as that of primary murine islets.Flow cytometry and Hoechst 33342 nuclear stain were utilized for detecting cell apoptotic rate in each group.The protein expressions of p-JNK, p-p38, JNK, p38, Bcl-2 and Bax were detected by Western blot.And the data were processed by one-way ANOVA or t test.Results:The proportion of dead islet cells in H/R group was (29.47±2.65)% and it was significantly lower than that in normal group (7.63±1.53)%.And the inter-group differences were statistically significant ( P<0.001). The proportion of dead islet cells was (20.63±3.07)% in H/R+ Me group.It was higher than that in H/R group (29.47±2.65)% and in H/R+ DMSO group (30.13±1.50)% and inter-group difference was statistically significant ( P<0.05 & P<0.01). Under the stimulation of high glucose, the insulin secretion level of islet in H/R+ Me group was (1.76+ 0.08) mg/L, which was higher than that in H/R group and H/R+ DMSD group(1.24±0.14)mg/L and(1.27±0.05)mg/L, and the difference was statistically significant[(1.76±0.08) vs. (1.24±0.14) mg/L; (1.76±0.08) vs.(1.27±0.05) mg/L, P<0.01]. There was no significant effect on cell viability after Me dosing within a certain concentration range (0-40 μmol/L). After Me dosing (5 μmol/L), cell viability of H/R-treated Min6 cells was significantly higher than that without Me.And the difference was statistically significant[(1.19±0.03) vs.(1.00±0), P<0.01]. As compared with H/R and H/R+ DMSO groups, overall apoptotic rate declined in H/R+ Me group (Hoechst 33342 stain: 14.50%±1.05% vs. 23.30%±1.18%, 14.50%±1.05% vs. 22.77%±1.75%, P<0.001; Flow cytometry: 4.36%±0.54% vs. 21.44%±1.02%, 4.36%±0.54% vs. 21.68%±3.06%, P<0.01). The expressions of p-JNK and p-p38 were down-regulated (p-JNK: 0.77±0.06 vs. 1.03±0.05, 0.77±0.06 vs.0.93±0.04, P<0.001; p-p38: 0.80±0.05 vs. 1.01±0.08; 0.80±0.05 vs. 1.00±0.05, P<0.05) while Bcl-2/Bax ratio rose (1.62±0.13 vs. 0.72±0.10, 1.62±0.13 vs. 0.74±0.13, P<0.01). Conclusions:Me can improve the viability and function of islets and suppress the apoptosis of Min6 cells after H/R.The mechanism is correlated with JNK and p38 MAPK signaling pathways.

BACKGROUND: Cardiovascular (CV) disease is the leading cause of morbidity and mortality in adults with type 2 diabetes (T2D). The aim of this study was to determine the CV risk in Chinese patients with T2D based on the 2019 European Society of Cardiology (ESC) and the European Association for the Study of Diabetes (EASD) guidelines on diabetes, pre-diabetes, and CV diseases. METHODS: A total of 25,411 patients with T2D, who participated in the study of China Cardiometabolic Registries 3B study, were included in our analysis. We assessed the proportions of patients in each CV risk category according to 2019 ESC/EASD guidelines. RESULTS: Based on the 2019 ESC/EASD guidelines, 16,663 (65.6%), 1895 (7.5%), and 152 (0.6%) of patients were included in "very high risk," "high risk," and "moderate risk" categories, respectively. The proportions of patients in each category varied based on age, sex, body mass index, and duration. While 58.7% (9786/16,663) of elderly patients were classified to "very high risk" group, 89.6% (3732/4165) of patients with obesity were divided into "very high risk" group. Almost all patients with a duration of diabetes >10 years had "very high risk" or "high risk." However, 6701 (26.4%) of Chinese T2D patients, who had shorter duration, and one or two risk factors, could not be included in any category (the "unclear risk" category). CONCLUSIONS In China, most patients with T2D have "very high" or "high" CV risk based on 2019 ESC/EASD guidelines. However, the risk of patients in "unclear risk" group needs to be further classified.

Objective To analyze the epidemiological characteristics of syphilis in Jiading District of Shanghai from 2014 to 2018, and to provide a scientific basis for the development of future syphilis prevention and control work. Methods According to the date of onset, all syphilis cases in the infectious disease report information management system from 2014 to 2018, and their epidemic characteristics were analyzed using descriptive epidemiological methods. Results A total of 2 992 cases of syphilis were reported in Jiading District from 2014 to 2018, with an average annual incidence of 38.89/100 000. The overall incidence showed a downward trend year by year. Recessive syphilis was the main cause, and the incidence increased year by year. Fetal syphilis was relatively small and the incidence decreased year by year. The composition ratios of recessive syphilis, primary syphilis, secondary syphilis, and tertiary syphilis in different years were significantly different, and the differences were statistically significant (χ²=26.955, P<0.05). The peak time of syphilis was from March to June. The reported cases were mainly registered population, with a male to female ratio of 1.04:1. There were significant gender differences in the reported incidence of syphilis in each period in different years, and the gender difference between primary syphilis and secondary syphilis was statistically significant (χ²=17.793, P=0.001<0.05; χ²=12.701, P=0.013<0.05). There was no significant difference in gender between recessive syphilis, tertiary syphilis, and fetal syphilis (P>0.05). 20~39 years old had the highest incidence rate of syphilis. The areas with high incidence were mainly concentrated in the old urban area of Jiading Center and areas with high population density. The occupational distribution was mainly concentrated in young and middle-aged household workers and unemployed people, workers and elderly retirees. Conclusion In recent years, the syphilis epidemic in Jiading District of Shanghai has shown a downward trend. However, the situation of prevention and control was still severe. It is necessary to continue to improve the level of syphilis detection, and to detect and treat syphilis early. Meanwhile, it is important to strengthen publicity and education in key areas and key populations, and increase awareness of disease prevention to reduce the incidence of syphilis.

Objective To analyze the incidence and epidemic characteristics of Class A and B infectious diseases in Jiading District of Shanghai from 2014 to 2019，understand the prevention and control effects of infectious diseases in recent years，and provide a reference for the formulation of future prevention and control strategies and measures for infectious diseases． Methods According to the " China Disease Prevention and Control Information System"，statistical analysis was conducted on the data of Class A and B infectious diseases in Jiading District of Shanghai from 2014 to 2019． Results A total of 11 862 cases of Class A and B infectious diseases were reported in Jiading District of Shanghai from 2014 to 2019，with an average annual incidence rate of 127.34/100000． The overall reported incidence rate showed a downward trend (χ²=36.354，P =0.000<0.05) ．The top five infectious diseases with an average annual incidence were syphilis，gonorrhea，tuberculosis，scarlet fever，and hepatitis B．The incidence rate in the central area of Jiading District was high over the years，and the incidence rate in the north and south was low．The incidence of males was higher than that of females，and the difference was statistically significant (χ²=818.269，P=0.000<0.05) ．The high incidence age was 5- years old， followed by 20- years old. The top three occupations in terms of morbidity were workers, housework, unemployed，and retired．In terms of onset time，December and May-June were the two peak periods; February was the trough．Conclusion Class A and B infectious diseases in Jiading District of Shanghai showed a downward trend from 2014to 2019． Blood-borne and sexually transmitted infections and respiratory infectious diseases are still infectious diseases that need to be focused on prevention and control，mainly syphilis，gonorrhea and tuberculosis. Targeted prevention measures should be formulated in conjunction with peak onset times and key populations to further reduce the incidence of Class A and B infectious diseases．
