ObjectiveThe study explores the influence of voluntary wheel running on the behavioral abnormalities and the activation state of the hypothalamic-pituitary-adrenal (HPA) axis in autism spectrum disorder (ASD) rats through gut microbiota. MethodsSD female rats were selected and administered either400 mg/kg of valproic acid (VPA) solution or an equivalent volume of saline via intraperitoneal injection on day 12.5 of pregnancy. The resulting offspring were divided into 2 groups: the ASD model group (PASD, n=35) and the normal control group (PCON, n=16). Behavioral assessments, including the three-chamber social test, open field test, and Morris water maze, were conducted on postnatal day 23. After behavioral testing, 8 rats from each group (PCON, PASD) were randomly selected for serum analysis using enzyme-linked immunosorbent assay (ELISA) to measure corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT) concentration, to evaluate the functional state of the HPA axis in rats. On postnatal day 28, the remaining 8 rats in the PCON group were designated as the control group (CON, n=8), and the remaining 27 rats in the PASD group were randomly divided into 4 groups: ASD non-intervention group (ASD, n=6), ASD exercise group (ASDE, n=8), ASD fecal microbiota transplantation group (FMT, n=8), and ASD sham fecal microbiota transplantation group (sFMT, n=5). The rats in the ASD group and the CON group were kept under standard conditions, while the rats in the ASDE group performed 6 weeks of voluntary wheel running intervention starting on postnatal day 28. The rats in the FMT group were gavaged daily from postnatal day 42 with 1 ml/100 g fresh fecal suspension from ASDE rats which had undergone exercise for 2 weeks, 5 d per week, continuing for 4 weeks. The sFMT group received an equivalent volume of saline. After the interventions were completed, behavioral assessments and HPA axis markers were measured for all groups. ResultsBefore the intervention, the ASD model group exhibited significantly reduced social ability, social novelty preference, spontaneous activity, and exploratory interest, as well as impaired spatial learning, memory, and navigation abilities compared to the normal control group (P<0.05). Serum concentration of corticotropin-releasing hormone (CRH), adrenocorticotropic hormone (ACTH), and corticosterone (CORT) in the PASD group were significantly higher than those in the PCON group (P<0.05). Following 6 weeks of voluntary wheel running, the ASDE group showed significant improvements in social ability, social novelty preference, spontaneous activity, exploratory interest, spatial learning, memory, and navigation skills compared to the ASD group (P<0.05), with a significant decrease in serum CORT concentration (P<0.05), and a downward trend in CRH and ACTH concentration. After 4 weeks of fecal microbiota transplantation in the exercise group, the FMT group showed marked improvements in social ability, social novelty preference, spontaneous activity, exploratory interest, as well as spatial learning, memory, and navigation abilities compared to both the ASD and sFMT groups (P<0.05). In addition, serum ACTH and CORT concentration were significantly reduced (P<0.05), and CRH concentration also showed a decreasing trend. ConclusionExercise may improve ASD-related behaviors by suppressing the activation of the HPA axis, with the gut microbiota likely playing a crucial role in this process.

Aim To discover the potential active compounds and possible mechanisms in rheumatoid arthritis (RA) treatment with Zhi-Huang-Zhi-Tong powder (ZHZTP) by using network pharmacology and in vitro study. Methods The active ingredient targets and disease targets of Zhihuang Zhitong Powder were searched and screened by database; they intersected to get a common target; and the "drug-component-target" relationship network diagram was constructed for GO and KEGG enrichment analysis of the overlapping genes; then the core components were docked with the core targets. Finally, based on the inflammation model of HUVECs in vitro, the efficacy and mechanism of Zhihuang Zhitong powder were verified by MTT method, plate scratch test and Western blot. Results Active compounds involved in RA treatment were screened in the present study, and the top two were ursolic acid and emodin, all playing crucial roles in RA treatment with ZHZTP. Additionally, the key target was AKTA, TNF and IL-6. GO and KEGG enrichment analysis revealed that ZHZTP regulated BP, MF and CC, and also focused on regulating AKTA, TNF and IL-6 signaling pathway. Molecular docking showed that interactions between key active compounds and key targets were stable. In vitro ZHZTP significantly inhibited cell viability and migration of TNF-a-stimulated HUVECs, and the involved mechanism may be associated with PI3K/AKT/m-TOR signaling. Conclusions The present study reveals that the potential active compounds of ZHZTP are ursolic acid and emodin, and moreover, the involved mechanisms of ZHZTP for RA treatment are associated with PI3 K/AKT/m-TOR signaling.

The early response of plant auxin gene family Aux/IAA (auxin/indole-3-acetic acid) and its interaction with auxin response factor (ARF) are important pattern to regulate plant growth and development. This work identified 28 StoIAA and 24 StoARF members based on the whole genome data of the medicinal plant Senna tora L., which were classified into 10 and 8 subfamilies, respectively. Phylogenetic tree and collinearity analysis showed that S. tora has close evolutionary relationship with the IAA and ARF homologous genes of Glycine max, Medicago truncatula, and the segment duplication events dominate the expansion of StoIAA and StoARF. Gene structure analysis showed that the vast majority of StoIAA and StoARF contain characteristic conserved domain. Transcriptome data showed that StoIAAs and StoARFs were expressed in leaves, roots and seeds, some members had tissue specific expression. The StoIAA and StoARF promoter region most contain functional elements related to stress response, growth and development, hormone induction and secondary metabolism. In addition, gene expression analysis showed that many StoIAAs and StoARFs can quickly respond to drought and salt stress and exhibited same expression patterns under both stress condition. The yeast two-hybrid experiment confirmed that StoARF8 and StoARF10 exhibit varying degrees of interaction with multiple StoIAA proteins, respectively. The above results provide a basis for further biological functional analysis of the Aux/IAA and ARF gene family of S. tora.

OBJECTIVE: To assess the risk of aristolochic acid (AA)-associated cancer in patients with AA nephropathy (AAN). METHODS: A retrospective study was conducted on patients diagnosed with AAN at Peking University First Hospital from January 1997 to December 2014. Long-term surveillance and follow-up data were analyzed to investigate the influence of different factors on the prevalence of cancer. The primary endpoint was the incidence of liver cancer, and the secondary endpoint was the incidence of urinary cancer during 1 year after taking AA-containing medication to 2014. RESULTS: A total of 337 patients diagnosed with AAN were included in this study. From the initiation of taking AA to the termination of follow-up, 39 patients were diagnosed with cancer. No cases of liver cancer were observed throughout the entire follow-up period, with urinary cancer being the predominant type (34/39, 87.17%). Logistic regression analysis showed that age, follow-up period, and diabetes were potential risk factors, however, the dosage of the drug was not significantly associated with urinary cancer. CONCLUSIONS No cases of liver cancer were observed at the end of follow-up. However, a high prevalence of urinary cancer was observed in AAN patients. Establishing a direct causality between AA and HCC is challenging.

ObjectiveTo explore the characteristics of circadian rhythm of blood pressure in patients with masked hypertension （MH） and its relationship with twelve two-hour peirods， providing a basis for early detection and intervention of MH. MethodsPatients who underwent 24-hour ambulatory blood pressure examination in the ambulatory blood pressure room of Jiangsu Province Hospital of Chinese Medicine from January to December 2022 were enrolled， and according to their outpatient blood pressure measurements， 24-hour ambulatory blood pressure monitoring and follow-up survey results， the MH， essential hypertension （EH） and normal blood pressure groups were classified， with 50 cases in each group. The general data， office blood pressure and 24-hour ambulatory blood pressure monitoring data were collected. The circadian rhythm of blood pressure including 24-hour average systolic blood pressure （24h SBP）， daytime average systolic blood pressure （d SBP）， nighttime average systolic blood pressure （n SBP）， 24-hour average diastolic blood pressure （24h DBP）， daytime average diastolic blood pressure （d DBP）， and nighttime average diastolic blood pressure （n DBP） were compared among the groups， and the nighttime blood pressure dipping percentage was calculated. The type of circadian rhythm was determined based on the nighttime blood pressure dipping percentage. The variability of blood pressure including 24h SBP standard deviation （24h SBP-SD）， d SBP standard deviation （dSBP-SD）， n SBP standard deviation （nSBP-SD）， 24h DBP standard deviation （24h DBP-SD）， d DBP standard deviation （dDBP-SD）， and n DBP standard deviation （nDBP-SD） were compared among groups， and the corresponding coefficient of variation （CV）， that is， 24h SBP-CV， d SBP-CV， n SBP-CV， 24h DBP-CV， d DBP-CV and n DBP-CV， were calculated. Based on the 24-hour ambulatory blood pressure monitoring results， the twelve two-hour average SBP and DBP in each group were calculated and compared. Simultaneously， patients with EH were divided into grades 1， 2， and 3 for further stratified analysis. ResultsThe age of the MH group was significantly higher than that of the EH group and the normal blood pressure group （P＜0.01）. The body mass index （BMI） and the proportion of smoking and alcohol consumption in the MH group and the EH group were significantly higher than those in the normal blood pressure group （P＜0.05 or P＜0.01）. In the normal blood pressure group， there were 49 dipper patterns （98.0%） and one non-dipper pattern （2.0%）； in the MH group， there were two dipper patterns （4.0%）， 29 non-dipper patterns （58.0%） and 19 reverse-dipper patterns （38.0%）； in the EH group， there were 20 dipper patterns （40.0%）， 23 non-dipper patterns （46.0%） and seven reverse-dipper patterns （14.0%）. Compared to the normal blood pressure group， the groups of MH and EH had significantly decreased proportion of dipper pattern and increased proportion of non-dipper and reverse-dipper pattern （P＜0.01）； the proportion of dipper pattern in the MH group was lower than that in the EH group， while the proportion of reverse-dipper pattern was higher （P＜0.01）. Compared to those in the normal blood pressure group， n SBP and n DBP in the MH group， as well as the the average SBP and average DBP at Zi hour （子时， 23：00-1：00）， Chou hour （丑时， 1：00-3：00）， Yin hour （寅时， 3：00-5：00）， Mao hour （卯时， 5：00-7：00） and average SBP at Hai hour （亥时， 21：00-23：00） in the MH group increased，while the average DBP at Si hour （巳时， 9：00-11：00） decreased （P＜0.01）； 24h SBP， 24h DBP， d SBP， d DBP， n SBP， and n DBP，d SBP-SD， n SBP-SD，n DBP-SD increased， as well as the average SBP and average DBP at twelve two-hour periods increased in the EH group，while the 24h SBP-CV， 24h DBP-CV，and d DBP-CV in the EH group decreased（P＜0.05 or P＜0.01）. The EH group had higher 24h SBP， 24h DBP， d SBP， d DBP， n SBP， n DBP， 24h DBP-SD and n DBP-SD ， as well as higher average SBP and DBP at all twelve two-hour periods， and lower d DBP-CV than the MH group（P＜0.05 or P＜0.01）. The EH group had 18 cases of grade 1 （36.0％）， 19 cases of grade 2 （38.0％） and 13 cases of grade 3 （26.0％）， with no significant differences among groups （P＞0.05）. ConclusionThe circadian rhythm of blood pressure in MH patients are mostly non-dipper and reverse-dipper patterns， and the abnormal elevation of blood pressure is obvious at Zi hour， Chou hour， Yin hour and Mao hour （23：00-7：00）.

Di-(2-ethylhexyl) phthalate (DEHP) is currently one of the most widely used plasticizers, widely found in all kinds of items, such as children’s toys and food packaging materials, but also added to wallpaper, cable protective agents and other building decoration materials. DEHP is toxic and absorbed by the human body through respiratory tract, digestive tract and skin contact, which can cause damage to multiple systems, especially the male reproductive system, and testis is an important target organ. Oxidative stress injury is the core mechanism of spermatogenesis disorder caused by DEHP. DEHP exposure can cause oxidative stress or reactive oxygen species (ROS) increase in germ cells, and on this basis, promote cell apoptosis or cause excessive autophagy. The toxicity of DEHP to Leydig cells is mainly to interfere with the synthesis of steroid hormones. For Sertoli cells, ferroptosis and destruction of the blood-testis barrier are common injury mechanisms. In addition, gene methylation caused by DEHP not only affects the spermatogenic process, but also has epigenetic effects on offspring. In this paper, we reviewed the pathological damage, germ cell toxicity and epigenetic effects of DEHP on testis, and focused on the damage and molecular mechanism on testicular spermatogenic cells, Leydig cells and Sertoli cells. Future research is required to elucidate the body’s clearance mechanism and treatment plan after exposure to DEHP and whether DEHP will damage the function of myoid cells. It is hoped that this can provide new ideas for prevention and treatment of male reproductive disorders resulting from long-term exposure to plastic products.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Objective:To understand the epidemiological characteristics of fatal drowning in children in Zhejiang Province in 2022, analyze factors such as the swimming ability of children, the caregiver behavior at drowning site, types of first aid personnel and methods of first aid of unintentional fatal drowning and provide evidence for targeted intervention.Methods:Using the "Survey Form of Fatal Drowning Case in Children" designed by National Center for Chronic and Non-communicable Disease Control and Prevention of the China CDC, we collected case information of children aged 0-17 years who died due to drowning in Zhejiang in 2022 from medical history/death investigation records, telephone interviews, and home visits.Results:A total of 341 fatal drowning cases in children occurred in Zhejiang in 2022 and 330 cases were investigated (96.77%). The male to female of the cases was 2.33∶1, most cases were aged 15-17 years and 0-4 years, and 54.24% of fatal drowning cases occurred in children from other provinces. In the drowning cases, 83.33% were unintentional ones, and the proportion of intentional fatal drowning cases in children increased with age. Fatal drowning cases mainly occurred in open natural water bodies and public water storage facilities. More fatal drowning cases occurred in open natural water bodies in older children, while more fatal drowning cases occurred in public water storage facilities in younger children. In 275 children who died due to unintentional drowning, 73.09% could not swim, and only 1.09% were fully supervised by adults within an arm's length. First aid personnel, mainly medical staffs, bystanders and adult caregivers, were present for 47.63% fatal drowning cases. The proportion of the cases who had cardiopulmonary resuscitation as the first aid within 5 minutes was 2.18%.Conclusions:Drowning poses a serious threat to children's lives and there are differences in reasons and locations of fatal drowning in children in different age groups in Zhejiang Province in 2022. It is necessary to conduct to interventions to improve children's swimming skills, strengthen effective adult care and conduct health education about field first aid of drowning to reduce the incidence of drowning and related deaths in children.
