Objective: To assess the awareness and associated factors of wild mushroom poisoning among students in Guizhou Province, so as to provide a scientific foundation for wild mushroom poisoning prevention and control among students. Methods: By a multi stage stratified cluster random sampling method, 1 162 students from Guizhou Province were selected in May 2024. The questionnaire survey was administered to evaluate knowledge regarding wild mushroom poisoning. Data were analyzed employing the χ 2 test and Logistic regression model. Results: Among the nine questions assessing awareness of wild mushroom poisoning, only three had the awareness rate exceeding 70%. Binary Logistic regression analysis revealed that students who "actively learn about the prevention of wild mushroom poisoning" ( OR=0.48, 95%CI =0.26-0.92) and "spread knowledge about wild mushroom poisoning to others" ( OR=0.47, 95%CI =0.33-0.69) scored higher on the wild mushroom poisoning knowledge questions ( P <0.05). Conversely, students with a habit of consuming wild mushrooms ( OR=1.52, 95%CI =1.15-2.02) scored lower ( P < 0.05 ). 42.3% of the students suggested that scientific dissemination and publicity about wild mushrooms should be intensified. Conclusions The awareness rate of wild mushroom poisoning knowledge among students in Guizhou Province requires further attention. Comprehensive knowledge should be disseminated systematically through various channels to further improve students awareness of the prevention and control of wild mushroom poisoning.

Objective:To analyze the difference and reliability of blood 17-hydroxyprogesterone (17-OHP), an indirect screening index for congenital adrenal hyperplasia (CAH), between preterm and full-term infants.Methods:In this retrospective cross-sectional study, a total of 210 285 newborns who underwent CAH screening at the Neonatal Screening Center of Shanghai Children′s Hospital from January 2019 to December 2022 were collected, including 14 312 premature infants and 195 973 full-term infants.The concentration of 17-OHP in dried blood spots on filter paper was determined by an automatic fluorescence analyzer.The distribution of 17-OHP levels in preterm and full-term infants and its statistical index were analyzed.The Kolmogorov-Smirnov test was used for normal distribution.The skewed distribution data was converted into approximately normal distribution using Box-Cox.Outliers were eliminated by the interquartile range method.The cumulative frequency distribution map was drawn by R language programming.The 99.5 th percentile value was used as the screening threshold and compared with the reference value given by the manufacturer or laboratory and with the reference change value (RCV). Results:According to the threshold provided by the laboratory, 26.76‰ of premature infants were tested positive in preliminary screening, and 4 were confirmed with an incidence of 1∶3 578, while 0.79‰ of full-term infants were tested positive in preliminary screening, and 11 were confirmed with an incidence of 1∶17 816.The thresholds for CAH screening established indirectly were 20.35 nmol/L in preterm infants and 10.78 nmol/L in full-term infants.The relative deviations between the indirect CAH screening thresholds and the manufacturer′s or laboratory′s CAH screening thresholds were higher than the RCV, respectively.According to the indirect CAH screening thresholds, the negative and positive coincidence rates of 65 samples in 13 batches from the Centers for Disease Control and Prevention interlaboratory quality assessment program in the United States reached 100%.A retrospective analysis of 210 285 neonates showed that 17-OHP concentration was higher than the screening threshold in all CAH-positive neonates.The application of this screening threshold reduced the false positive rate of preterm infants by 59.79%.Conclusions:It is feasible to establish the CAH screening thresholds for premature and full-term infants by an indirect method, which can improve the efficiency of screening and provide better diagnostic basis for clinical practice.

Objective: To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD. Methods: Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model. Results: A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966). Conclusion The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.

Objective:To investigate the effect of visceral fat thickness before operation on the operative difficulty and postoperative complications in renal transplantation recipients.Methods:A total of 179 patients diagnosed with end-stage renal disease who underwent kidney transplantation in Beijing Friendship Hospital, Capital Medical University from January 2020 to January 2022 were retrospectively included. According to the visceral fat thickness measured by CT before transplantation (distance from anterior wall of abdominal aorta to parietal peritoneum at 1 cm above umbilicus), patients were divided into two groups, with 103 patients in thin visceral fat group with visceral fat thickness ≤7.5 cm and 76 patients in thick visceral fat group with visceral fat thickness>7.5 cm. The epidemiological data before renal transplantation, operative time, intraoperative blood loss, postoperative complications, renal function after transplantation and patients′ recovery state were analyzed and compared between the two groups. Measurement data were expressed as mean±standard deviation ( ± s), and independent sample t-test was used for comparison between groups. The Chi-square test was used to compare the count data. Results:The mean age and body mass index of patients in thin visceral fat group [(38.70±11.50) years and (21.28±2.93) kg/m 2] were lower than those in thick visceral fat group [(43.14±11.42) years and (24.78±3.37) kg/m 2], and the differences were statistically significant ( P< 0.05). There was no significant difference in other preoperative epidemiological data between the two groups ( P>0.05). In terms of operation difficulty, the mean operation time of thin visceral fat group was (117.16±34.33) min, which was significantly shorter than that of thick visceral fat group (137.11±20.02) min. The mean intraoperative blood loss in the thin visceral fat group was (89.12±45.95) mL, which was lower than that in the thick visceral fat group (125.39±54.88) mL, the differences were statistically significant ( P<0.001). In terms of postoperative complications, 41 patients in the thin visceral fat group had postoperative infection, incision pain and intraoperative effusion, and the incidence was 39.8% (41/103), which was significantly lower than that in the thick visceral fat group (78.9%, 60/76), the difference was statistically significant ( P<0.001); However, there was no significant difference in the incidence of Clavien-Dindo grade 3 or higher complications between the two groups ( P> 0.05). There was no significant difference in serum creatinine levels at 3, 5, 7 days and 1, 2 months after surgery among patients with different visceral fat thickness ( P> 0.05). However, the mean serum creatinine level in the thin visceral fat group was (116.06±36.45) μmol/L, which was lower than that in the thick visceral fat group (133.35±72.26) μmol/L, and the difference was statistically significant ( P=0.038). There was no significant difference in the incidence of delayed renal function recovery between the two groups ( P> 0.05). At the same time, there was no significant difference in postoperative drainage tube indwelling time and hospital stay between the two groups ( P> 0.05). Conclusions:The thicker visceral fat in end-stage renal disease patients before transplantation, the higher the incidence of general postoperative complications, but the severity of complications, patients′ recovery after transplantation and the short-term function of the transplanted kidney are not significantly related to the thickness of visceral fat in the recipients. Meanwhile, although the visceral fat thickness of the recipients in this study was correlated with serum creatinine levels at 3 months after transplantation, its correlation with long-term graft renal function and graft survival time remains to be further studied.

Periodontitis is a chronic inflammatory and destructive disease in which plaque acts as an initiator.Recruitment of host im-mune cells and production of multiple inflammatory mediators leads to periodontal tissue damage.Programmed cell death(PCD)is a self-destructive process that is actively initiated by cells under specific conditions and can be mainly categorized into apoptosis,necrop-tosis,autophagy,pyroptosis,ferroptosis,cuproptosis,etc.Different types of programmed cell death have their own distinctive roles in periodontitis.In this review,we summarizes the characteristics of different types of PCD and their role in the progression of periodonti-tis,in order to provide new research ideas on the pathogenic mechanism of periodontitis and more references for the precise treatment of periodontitis.
