BACKGROUND: Physical activity, sedentary behavior (SB), and sleep duration are associated with brain health. Effects of those on developing Parkinson's disease (PD) are poorly investigated. This study aimed to examine the independent and joint associations of physical activity, SB, sleep with PD risk. METHODS: We analyzed data on 401,697 participants from the UK Biobank cohort, which was enrolled in 2006-2010. Physical activities were measured based on a questionnaire. Sleep and SB time were defined through self-reported total number of hours. Models fitted with restricted cubic spline were conducted to test for linear and non-linear shapes of each association. Cox proportional hazards regression models were used to estimate the association of three modifiable behaviors. RESULTS: Our analytic sample included 401,697 participants with 3030 identified cases of PD (mean age, 63 years; 62.9% male). PD risk was 18% lower in the high total physical activity group (95% CI, 0.75-0.90), 22% lower in the high leisure-time physical activity (LTPA) group (95% CI, 0.71-0.86) compared with the low level and 14% higher in the high sleep duration group (95% CI, 1.05-1.24) compared to moderate group. Total SB time was irrelevant with PD risk, while high TV viewing showed a 12% increase of PD risk compared to the low group (95% CI, 1.02-1.22). Low computer use (0 h/day) was associated with a 14% higher risk compared to 1 h/day use (95% CI, 1.04-1.26). Those associations were independent. A combination of 7 h/day sleep, moderate-to-high computer use, and moderate-to-vigorous intensity of LTPA showed lowest PD risk (HR, 0.70; 95% CI, 0.57-0.85). CONCLUSIONS Physical activity, SB, and sleep were associated with PD risks separately. Our findings emphasize the possibility for changing these three daily activities concurrently to lower the risk of PD. These findings may promote an active lifestyle for PD prevention.

BACKGROUND: Neuroticism has been associated with numerous health outcomes. However, most research has focused on a single specific disorder and has produced controversial results, particularly regarding mortality risk. Here, we aimed to examine the association of neuroticism with morbidity and mortality and to elucidate how neuroticism affects trajectories from a healthy state, to one or more neuroticism-related disorders, and subsequent mortality risk. METHODS: We included 483,916 participants from the UK Biobank at baseline (2006-2010). Neuroticism was measured using the Eysenck Personality Questionnaire. Three clusters were constructed, including worry, depressed affect, and sensitivity to environmental stress and adversity (SESA). Cox proportional hazards regression and multistate models were used. Linear regression was used to examine the association between neuroticism and immune parameters and neuroimaging measures. RESULTS: High neuroticism was associated with 37 non-overlapping diseases, including increased risk of infectious, cardiometabolic, neuropsychiatric, digestive, and respiratory diseases, and decreased risk of cancer. After adjustment for sociodemographic variables, physical measures, healthy behaviors, and baseline diagnoses, moderate-to-high neuroticism was associated with a decreased risk of all-cause mortality. In multistate models, high neuroticism was associated with an increased risk of transitions from a healthy state to a first neuroticism-related disease (hazard ratio [HR] [95% confidence interval (CI)] = 1.09 [1.05-1.13], P  <0.001) and subsequent transitions to multimorbidity (1.08 [1.02-1.14], P  = 0.005), but was associated with a decreased risk of transitions from multimorbidity to death (0.90 [0.84-0.97], P for trend = 0.006). The leading neuroticism cluster showing a detrimental role in the health-illness transition was depressed affect, which correlated with higher amygdala volume and lower insula volume. The protective effect of neuroticism against mortality was mainly contributed by the SESA cluster, which, unlike the other two clusters, did not affect the balance between innate and adaptive immunity. CONCLUSION This study provides new insights into the differential role of neuroticism in health outcomes and into new perspectives for establishing mortality prevention programs for patients with multimorbidity.

Objective To observe the clinical efficacy of Zishen Shujing decoction in the treatment of kidney deficiency and liver depression type premature ovarian failure(POF).Methods A total of 70 female POF patients who visited the Fourth Clinical Medical College of Guangzhou University of Traditional Chinese Medicine from July 2023 to April 2024 were selected as the research subjects,they were divided into traditional Chinese medicine(TCM)treatment group(n=35)and Western medicine treatment group(n=35)by using a random number table method.Western medicine treatment group was treated with femostone,and TCM treatment group was treated with Zishen Shujing decoction.Differences of TCM syndrome scores and clinical efficacy were compared between two groups before and after treatment,and changes of peripheral blood follicle-simulating hormone(FSH),anti-Müllerian hormone(AMH),anal follicle count(AFC)and interleukin(IL)-4,IL-6 before and after treatment were compared.Results The effective rate of TCM treatment group was higher than that of Western medicine treatment group,the difference was statistically significant(P<0.05).The TCM syndrome scores after treatment were lower than before treatment,and TCM treatment group was lower than Western medicine treatment group,the difference was statistically significant(P<0.05).After treatment,FSH levels in two groups were lower than before treatment,AMH and AFC levels were higher than before treatment,and improvement of hormone levels,AMH and AFC in TCM treatment group was better than that in Western medicine treatment group,with statistical significance(P<0.05).After treatment,the anti-inflammatory factors IL-4 were increased,and the pro-inflammatory factors IL-6 were decreased,and the increase effect of anti-inflammatory factors and the decrease effect of pro-inflammatory factors in TCM treatment group were better than those in Western medicine treatment group with statistical significance(P<0.05).Conclusion Zishen Shujing decoction can improve the clinical symptoms,serum hormone levels of POF patients with kidney deficiency and liver depression,improve ovarian function,reduce immune inflammation,reduce oxidative stress,and effectively improve the quality of life of patients.

Objective:To measure the distance between the fetal bladder neck and the rectal end using prenatal MRI and analyze the developmental patterns of this distance and the gender differences in the second and third trimesters of pregnancy.Methods:This retrospective cohort study involved fetuses born at Guangzhou Women and Children's Medical Center, Guangzhou Medical University after regular prenatal examinations from January 2019 to December 2022 and confirmed to have typical anorectal structures after birth. These fetuses had undergone prenatal MRI examinations for reasons other than abdominal issues. The morphology of the fetuses' colons, rectums, and bladders was observed, and the vertical distance between the bladder neck and the rectal end was measured on sagittal T1weighted imaging. Differences in the distance between male and female fetuses were analyzed. The fetuses were divided into five groups based on their gestational age at the time of MRI examination (23-24 weeks, >24-26 weeks, >26-28 weeks, >28- 30 weeks, and >30-32 weeks), and the changes in the distance with gestational age were analyzed. Statistical analysis was performed using t-test, Kruskal-Wallis test, and Spearman correlation analysis. Pairwise comparisons among multiple groups were conducted using the Bonferroni method. Results:(1) A total of 142 fetuses were included in this study, all of which were singletons, with 73 males (51.4%) and 69 females (48.6%). The gestational age at the MRI examination was 28 weeks (26-30 weeks). (2) All fetuses had meconium filling the entire rectum and colon, with the rectal end located 0.570-2.610 cm below the bladder neck. (3) The distance between the bladder neck and the rectal end was shorter in male fetuses than in female fetuses [(1.140±0.261) vs. (1.519±0.405) cm, t=－6.58, P<0.001]. (4) In female fetuses, four pairs of groups showed statistically significant differences in the distance (23-24 weeks group vs. >26-28 weeks, >28- 30 weeks, and >30-32 weeks groups, and >24-26 weeks group vs. >30-32 weeks group). However, only two groups of male fetuses (23-24 weeks group vs. >28-30 weeks group) had statistically significant differences in the distance (all P<0.005). (5) The distance was moderately correlated with gestational age in male fetuses ( r=0.42, P<0.001), but they were strongly correlated in female fetuses ( r=0.66, P<0.001). Conclusions:The distance between the bladder neck and the rectal end in fetuses shows certain developmental patterns and gender differences in pregnancy's second and third trimesters. The correlation between the value and gestational age is stronger in female fetuses.

Objective:To compare the quality of sleep and rehabilitation after routine surgery versus day surgery in pediatric patients with snoring.Methods:This was a prospective study.Seventy pediatric patients with snoring, aged 4-6 yr, of American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ, undergoing adenoidectomy and/or tonsillectomy in the Guangzhou Women and Children′s Medical Center from March to June 2023, were divided into routine surgery group (group R) and day surgery group (group D), with 35 cases in each group. A sleep-detecting bracelet was used to monitor the sleep status. The proportion of deep sleep, light sleep and rapid eye movement, sleep continuity score and the maximum and minimum heart rate were recorded on the night before surgery, the first and second night after surgery. Rehabilitation was assessed using Quality of Recovery-15 at 1 day before surgery and 24 and 48 h and 28 days after surgery.Results:Compared with group R, the maximum heart rate at the night before surgery was significantly decreased, the proportion of light sleep on the second night after surgery was increased, the proportion of rapid eye movement sleep on the second night after surgery was decreased, the scores for items on " getting support from hospital doctors and nurses", " feeling comfortable and in control", and " having a feeling of general well-being" and the total score of Quality of Recovery-15 were significantly decreased at 24 and 48 h after operation, and the score for items on " feeling rested" and " have had a good sleep" at 48 h after surgery was decreased in group D ( P<0.05). Conclusions:Pediatric patients with snoring have poor quality of early sleep and rehabilitation after day surgery compared with routine surgery.

African swine fever(ASF),caused by the African swine fever virus(ASFV),is a highly contagious infectious disease of pigs.This disease has been spread rapidly in China since 2018,po-sing a huge threat to China's pig farming industry.To rapid detect the ASFV,a loop-mediated iso-thermal amplification(LAMP)combined with the disposable nucleic acid visualization test strip was established for visual detection of the nucleic acid of ASFV B646L gene.The method was easy to operate without special instruments and equipment,while it effectively avoided the disadvantage of false positives caused by aerosol contamination.The method was able to detect 1.16 copies/μL of the recombinant plasmid in 50 min at 65 ℃.In addition,the method was specific with no cross-re-action with classical swine fever virus,porcine reproductive and respiratory syndrome virus,por-cine parvovirus,transmissible gastroenteritis virus.The results in this study provides a rapid,con-venient,sensitive and reliable method for early diagnosis and screening for ASFV suspected infec-tion cases.

ObjectiveTo investigate a suspected outbreak of carbapenem-resistant Acinetobacter baumannii （CRAB） nosocomial infection in an intensive care unit （ICU） and provide scientific evidence for prevention and control of multi-drug resistant nosocomial infection. MethodsClinical and epidemiological data of 4 patients with CRAB infection were retrospectively investigated in the ICU of Renji Hospital in November 2021. Environmental hygiene monitoring and multilocus sequence typing （MLST） were conducted and intervention measures were taken. ResultsA total of 4 cases with CRAB infection were identified， among which 1 case was determined to be community-acquired and3 cases were hospital-acquired. The isolated strains shared the same drug resistance， and were all classified into ST368 type. In the surface and hand samples （n=40）， 2 CRAB strains were detected in the air filter beside the bed of the first case， with a detection rate of 5%. After adopting comprehensive prevention and control strategies， including environmental cleaning and disinfection， hand hygiene， staff management and training， and supervision， no similar case with CRAB infection was found. ConclusionThis suspected outbreak of CRAB nosocomial infection may be induced by inadequate environmental cleaning and disinfection， and inadequate implementation of hand hygiene. Timely identification， investigation， and targeted measures remain crucial to effective control of possible nosocomial infection.

Objective: To establish a method for determining the content of bear bile powder in Longze Xiongdan capsules with taursodeoxycholic acid（TUDCA） and taurchenodeoxycholic acid（TCDCA） as indexes.
Methods: HPLC series evaporation photodetector was adopted on Chrom Core AQ C₁₈ column(4.6 mm×250 mm, 5 μm), with the mobile phase comprising of acetonitrile ( A ) and 5 mmol·L^-1 ammonium acetate solution (B) in a gradient elution (0-40 min, 25%A; 40-50 min, 25%A→29%A; 50-80 min, 29%A; 80-100 min, 29%A→40%A) at the flow rate of 1.0 mL·min^-1. The column temperature was 30 ℃. The ELSD was used, of which the drift tube temperature was 110 ℃ and the flow rate of carrier gas（N₂） was 2.5 L·min^-1.
Results: In the ranges of 1.069-9.57 μg and 0.740 46-7.404 64 μg, logarithms of the injected amount of TUDCA and TCDCA presented good linear relationships with logarithms of the peak area, respectively. The RSDs of precision, repeatability and stability tests were all lower than 2.0%. At three concentration levels the recoveries of TUDCA and TCDCA were 95.2%-97.7% and 91.9%-95.9%, respectively. Samples of 42 batches showed that the contents of TUDCA and TCDCA were 0.18-0.43 and 0.10-0.44 mg·granule^-1, respectively.
Conclusion: This method can be used for the quality control of bear bile powder in Longze Xiongdan capsules, thus provides a scientific basis for improving its quality standard.
