OBJECTIVE To evaluate the efficacy of Compound glutamine enteric-coated capsules in the treatment and prevention of radiotherapy- and chemotherapy-related intestinal dysfunction in patients with malignant tumors. METHODS PubMed， Embase， CNKI， and Wanfang data were searched to collect randomized controlled trial （RCT） and cohort studies comparing Compound glutamine enteric-coated capsules （experimental group） with or without other treatments versus other treatments or blank control （control group）. The search period was from the establishment of each database to November 19， 2025. After literature screening， data extraction， and quality assessment， a meta-analysis was performed using RevMan 5.4 software. RESULTS A total of 23 studies were included， involving 2 014 patients. Meta-analysis results showed that the effective rate in the experimental group was significantly higher than that in the control group， the overall incidence and moderate-to-severe incidence of radiotherapy- and chemotherapy-related intestinal dysfunction， quality of life scores， and interleukin-6 levels in the experimental group were significantly lower than those in the control group （ P ＜0.05）. However， no statistically significant differences were observed between the two groups in terms of Karnofsky Performance Status score improvement rate and tumor necrosis factor-α levels （ P ＞0.05）. The results of subgroup analysis based on different medications in the control group showed that， when used for treatment， regardless of whether patients in the control group received blank control or positive control， the efficacy in the experimental group was significantly higher than that in the control group （ P ＜0.05）. When used for prevention， compared with patients who received blank control in the control group， the overall incidence and the incidence of moderate-to-severe radiotherapy- and chemotherapy-related intestinal dysfunction in the experimental group were significantly reduced （ P ＜0.05）. No statistically significant difference was found in the overall incidence or incidences of moderate-to-severe radiotherapy- and chemotherapy-related intestinal dysfunction with positive control between the two groups （ P ＞0.05）. CONCLUSIONS Compound glutamine enteric-coated capsules can effectively treat and prevent radiotherapy- and chemotherapy-related intestinal dysfunction in patients with malignant tumors， improve patients’ quality of life， and alleviate inflammatory responses.

ObjectiveAs a common lifestyle habit, alcohol consumption has a controversial association with the onset of Parkinson’s disease (PD). To demonstrate the correlation between alcohol consumption and PD and to identify associated genes, we integrated findings from clinical surveys, genomics, transcriptomics, and animal experiments. MethodsWe investigated the alcohol consumption rates (including both before and after disease onset) among 244 PD patients in China and 177 PD patients from the U.S. NHANES database. Mendelian randomization (MR) analysis was performed using genome-wide association study (GWAS) data for three alcohol-related traits and seven PD-related datasets from the MRC IEU OpenGWAS database. Transcriptomic data from the substantia nigra of PD patients were obtained from three GEO datasets (GSE7621, GSE20141, and GSE49036) to analyze RIT2 gene transcription. Finally, three groups of animal experiments (water/20% ethanol/20% liquor, with 4 C57BL/6J mice per group) were conducted to examine changes in brain RIT2 gene expression and transcriptomic profiles following alcohol consumption. ResultsThe alcohol consumption rates among PD patients in China and the U.S. (9%-18.87%) were significantly lower than the general population rates of 15%-45% in their respective regions (P<0.001), suggesting a possible negative association between alcohol consumption and PD. Subsequently, in 21 bidirectional MR analyses using 3 alcohol-related GWAS datasets and 7 PD-related GWAS datasets, the forward MR analyses (alcohol intake as exposure, PD as outcome) yielded 12 negative associations (OR_IVW<1) and 9 positive associations (OR_IVW>1). Among these, only two negative associations reached statistical significance: alcohol intake frequency (OR_IVW=0.75, 95% CI: 0.60-0.93, P=0.010) and alcohol consumption (OR_IVW=0.20, 95% CI: 0.05-0.83, P=0.026). The forward MR analysis (alcohol intake→PD) identified 235 SNPs, annotated to 316 genes, while the reverse MR analyses (PD→alcohol intake) identified 37 SNPs, annotated to 53 genes. Notably, only the RIT2 gene appeared in both the forward and reverse MR analyses (alcohol intake→PD: rs28597806, rs8083110; PD→alcohol intake: rs4588066). RIT2 is selectively expressed in the human brain (FPKM: 5.259±2.103), with low or no expression in peripheral tissues (FPKM: <1). Analysis of three human substantia nigra transcriptomic datasets revealed a decreasing trend in RIT2 gene expression in PD patients (GSE20141 array signal: 3.49±1.23 vs. 2.33±0.87, P=0.044). Animal experiments demonstrated that administration of 20% ethanol or 20% liquor (approximately 8% ethanol) stimulated a >2-fold upregulation of RIT2 gene expression in the mouse brain. Furthermore, transcriptomic sequencing revealed that the two alcohol-treated groups exhibited 96 (20% ethanol vs. water control) and 4 (20% liquor vs. water control) differentially expressed genes, respectively, indicating that low-dose alcohol consumption can achieve RIT2 upregulation while minimizing impact on other brain genes. In addition to its anti-infective effects, low-dose alcohol consumption primarily influences signaling pathways related to neurodegenerative diseases such as PD and Prion diseases. ConclusionAlcohol consumption is generally considered as a harmful lifestyle habit. However, some studies have also shown a lower risk of mortality among individuals who consume low doses of alcohol (100 g/week of ethanol) or drink occasionally. Currently, one of the research focuses on alcohol consumption is whether the human body can benefit from low-dose alcohol intake. This study provides new evidence supporting a negative association between alcohol consumption and PD, and for the first time, through MR analysis, identifies the RIT2 gene as a potential mediator of the effect of alcohol consumption on PD. RIT2 is selectively expressed in the human brain. Building upon existing evidence indicating downregulated RIT2 gene expression in PD pathogenesis, our experiments confirm that low-dose alcohol consumption can upregulate RIT2 expression in the brain. In brief, alcohol consumption may suppress the pathogenesis of PD by upregulating RIT2 expression in the substantia nigra. China is facing a serious problem of population aging. This study offers important insights for long-term PD prevention and treatment strategies, with the aim of benefiting more potential PD patients through lifestyle modifications, thereby improving the quality of life of the aging population and reducing the economic burden on healthcare.

Objective To analyze the occurrence of postoperative pneumonia(POP)in a tertiary general first-class hospital in Shanghai,and provide basis for strengthening the implementation of POP prevention and control meas-ures for the target population.Methods The real-time monitoring data of healthcare-associated infection(HAI)from 2017 to 2023 were retrospectively surveyed.The occurrence of POP in all surgical patients(including minimal-ly invasive interventional surgery)were analyzed.Results A total of 701 postoperative patients had POP.The inci-dence of POP was 0.30％.Incidence of POP was higher in male patients than in female patients(0.48％vs 0.15％),in 65-year-old-population than in＜65-year-old-population(0.58％vs 0.17％),and in elective surgery than in emergency surgery(0.35％vs 0.27％),differences were statistically significant(all P＜0.05).The inter-val from postoperative time to POP occurrence in 701 POP patients was 6(4,10)days,with emergency surgery pa-tients developing POP later than elective surgery(7[4,11]days vs 6[3,10]days),and difference was statistically significant(P＜0.05).The top five departments with higher incidences of POP were neurosurgery(5.84％),cardi-ac surgery(4.01％),thoracic surgery(1.92％),abdominal surgery(0.74％),and minimally invasive intervention(0.17％).Incidence of POP in emergency neurosurgery was higher than that in elective neurosurgery(9.71％vs 2.14％),while incidences of POP in elective cardiac surgery and thoracic surgery were both higher than emergency surgery(5.09％vs 2.93％,2.46％vs 0.58％,respectively),differences were all statistically significant(all P＜0.05).A total of 675 strains of pathogens were detected from 701 POP patients,with Gram-negative bacteria being the major pathogens(n=520,77.04％).The predominant detected pathogens were Acinetobacter baumannii(n=119),Pseudomonas aeruginosa(n=116),Staphylococcus aureus(n=108),Klebsiella pneumoniae(n=104),and Stenotrophomonas maltophilia(n=47).Conclusion In the prevention and control of perioperative infection,the key populations for POP prevention and control should be males and those aged ≥65 years old,and the key depart-ments should be neurosurgery,cardiac/thoracic surgery,and abdominal surgery.Minimal invasive surgery also has the risk of POP,which should be paid more attention.

This study investigated the drug resistance and genetic relationships among strains co-existing in animals,the environ-ment,and the living quarters of employees at large-scale pig farms in certain regions of Shandong Province,to provide a scientific ba-sis for elucidating the transmission mechanisms of drug-resistant bacteria through bacterial traceability analysis.Samples were col-lected from two pig farms,and bacteria were isolated and purified.The species of the isolated strains were identified via 16S rRNA gene sequencing.Antimicrobial susceptibility testing was conducted with a VITEK-2 Compact system and the disk diffusion method for strains present in pigs,the environment,and living areas.Furthermore,whole-genome sequencing was performed on the Illumina Miniseq platform to annotate drug resistance genes,and multilocus sequence typing(MLST)and core genome single nucleotide poly-morphism(cgSNP)analyses were used to trace the resistant strains.Three species—Staphylococcus aureus,Pseudomonas aeruginosa,and Bacillus cereus—were isolated and cultured from animals,the environment,and employee living areas,and their distributions were analyzed.These strains exhibited diverse drug resistance spectra and genetic diversity.Additionally,the strains displayed highly consistent resistance profiles,resistance genes,ST types,and SNP loci in pig urine,soil both inside and outside the facility,human drinking water,and the cafeteria and dormitories.Our findings indicated a potential risk of transmission of opportunistic pathogens be-tween the pig farming area and the living quarters.Particular attention should be paid to the environmental transmission of methicillin-resistant Staphylococcus aureus.

Objective:To establish a cutoff level of anti-Müllerian hormone(AMH)which could help with the di-agnosis of polycystic ovary syndrome(PCOS)in adults,and to analyze the risk factors of metabolic syndrome(MS).Methods:A retrospectively analyzed 426 PCOS patients(PCOS group)and 205 healthy controls aged 20-39 years from the Health Checkup Center of the Gynecological Endocrine Center,Hunan Maternal and Child Health Hospital from January 2021 to December 2023.AMH diagnostic validity was estimated by receiver operating characteristic(ROC)curves.Patients were subgrouped into PCOS combined metabolic syndrome group(MS-PCOS)and the uncomplicated MS group(UMS-PCOS)according to metabolic status.Multivariate Logistic regression analysis was performed to determine the risk factors for MS in PCOS patients.Results:The serum AMH level was higher in PCOS group than that in the control group(8.42±3.71 ng/ml vs.2.99±0.94 ng/ml,P＜0.001).AMH cutoff for the diagnosis of PCOS was determined as≥4.87 ng/ml on ROC analysis,and the area under the curve is 0.981 with 92.7％sensitivity and 94.6％specificity.The prevalence of MS was 18.3％(78 ca-ses)in PCOS group.Subgroup analysis showed that MS-PCOS patients had higher waist circumference,BMI,fasting glucose,dyslipidemia,hypertension(BP＞130/85 mmHg),and hormone related index androgen level,but lower AMH vs.UMS-PCOS.Multivariate Logistic regression analysis identified insulin resistance(OR 39.17,95％CI 9.33-164.48),BMI ≥24 kg/m2(OR 3.72,95％CI 1.86-7.45),and hyperandrogenism(OR 2.56,95％CI 1.34-4.89)as independent risk factors of MS.AMH was negatively associated with MS,a single-unit increase in AMH was associated with an 17％decrease in odds of MS(OR 0.83,95％CI 0.73-0.95,P=0.006).Conclusions:Serum AMH levels were significantly higher in adult PCOS patients,with an optimal diagnostic threshold of 4.87 ng/ml.Hyperandrogenism and low AMH levels may predict a higher risk of MS,in addition to metabolism-related factors.

Objective To describe and analyze the current status,changing trend and influencing factors of the disease burden of cervical,endometrial and ovarian cancer in China from 1990 to 2021.Methods Data on incidence,mortality,disability-adjusted life year(DALY),and other indicators for cervical,endometrial and ovarian cancer were collected from the 2021 Global Burden of Disease database.Joinpoint regression models were used to analyze time trends,and age-period-cohort(APC)models assessed their impact on incidence and mortality.Spearman correlation analysis was performed to evaluate the relationship between the sociodemographic index(SDI)and the cancer indicators.Finally,the attributable risk factors for the disease burden were analyzed.Results From 1990 to 2021,age-standardized incidence rates of cervical and endometrial cancers in China significantly increased,while ovarian cancer showed no significant change.Age-standardized mortality,DALY,and years of life lost due to premature death(YLL)decreased significantly.The disease burden was heavier in middle-aged and older groups.APC model indicated an increase in cervical cancer incidence and a decrease in mortality over time.Furthermore,the incidence risks of cervical and endometrial cancers were elevated in successive birth cohorts,whereas a lower risk was observed for ovarian cancer.Correlation analysis showed significant associations between cancer incidence and mortality with SDI.Obesity has significantly contributed to the disease burden of common gynecologic cancers in China.Conclusion Mortality rates of cervical,endometrial and ovarian cancer have declined,while the incidence of cervical and endometrial cancers has significantly increased.The trends in incidence and mortality are influenced by age,period and cohort effects.Future efforts should focus on controlling risk factors like obesity to reduce the disease burden.

Objective To investigate how puerarin affects cognitive behavior and pro-inflammatory factors in the hippocampal formation of 52％(v/v)alcohol exposure/withdrawal in mice and reveal the underlying neuroimmunological mechanism by which puerarin improves alcohol-induced cognitive dysfunction.Methods A total of 120 adult female mice were randomly divided into control,52％alcohol,puerarin+52％alcohol,and normal saline(NS)+52％alcohol groups.The cognitive function of the animals was assessed using the Morris water maze,and the expression of target proteins in the hippocampal formation was detected using Western blotting and immunohistochemi-stry.Results The cognitive ability of mice in the puerarin+52％alcohol group was significantly higher than that of mice in the 52％alcohol and NS+52％alcohol groups.At the 20th hour after alcohol withdrawal,IL-6,TNF-α,and IL-1β expressions in the hippocampal formation of the puerarin+52％alcohol group were higher than those of the 52％and NS+52％alcohol groups.However,no significant difference could be observed in the expression levels of these cytokines between the puerarin+52％alcohol and control groups.Con-clusion In a female mouse model chronically exposed to 52％alcohol,puerarin can improve cognitive dysfunction during acute alcohol withdrawal,potentially related to the involvement of puerarin in regulating pro-inflammatory factor expressions in murine hippocampus formation.

ObjectiveTo investigate the effect and mechanism of Polygonatum neutral polysaccharides from sibiricum （PSP-NP） on colon injury in mice with chronic obstructive pulmonary disease （COPD）. MethodsMale C57BL/6J mice were randomly divided into a control group， a COPD model group， and a PSP-NP group. The COPD model was established using smoke exposure combined with intranasal LPS administration. The PSP-NP group was simultaneously treated daily with 200 mg/kg of PSP-NP via intragastric gavage， while the other groups received an equal volume of saline. HE staining was used to observe the pathological changes in the colon. ELISA was employed to detect the levels of LPS in serum and the expressions of ZO-1， Occludin， IL-6， and TNF-α in colon tissue. UPLC-MS was used to detect the types and contents of bile acids in colonic content， and to screen for differential bile acids. Differential microbial flora were identified using 16S rRNA gene sequencing， and correlation analysis was conducted with differential bile acids. PSP-NP was combined with the differential bile acids cholic acid （CA）， and deoxycholic acid （DCA） in vitro to analyze the binding capacity of PSP-NP for CA and DCA. PSP-NP was applied to NCM460 normal colonic epithelial cells cultured in CA and DCA. Cell migration ability was assessed using the scratch assay， and the mRNA expression levels of inflammatory cytokines TNF-α， IL-6， and NF-κB were measured by RT-qPCR. ResultsPSP-NP effectively improved colonic damage in COPD model mice， enhanced mechanical barrier function， alleviated inflammatory response， and regulated abnormal changes in colonic flora and bile acid metabolism. Correlation analysis further revealed that PSP-NP regulated colonic bile acid metabolism and reduced the redundancy of secondary bile acids by increasing the relative abundance of Bacteroidota， Verrucomicrobiota， Bacteroides， and Akkermansia， while decreasing the relative abundance of Lactobacillus and Bifidobacterium. Notably， in vitro binding assays demonstrated that PSP-NP bound to differential bile acids DCA and CA， with the strongest binding capacity for DCA at 58.2%. In cellular functional studies， DCA inhibited the migration ability of colonic epithelial cells NCM460 and significantly increased the relative mRNA expression levels of inflammatory factors TNF-α， IL-6， and NF-κB. Importantly， co-treatment with PSP-NP significantly ameliorated the impact of DCA on NCM460 cells. ConclusionsPSP-NP may significantly improve colonic damage in COPD model mice. The mechanism may involve the regulation of colonic bile acid metabolism and bile acid profiles through both microbial modulation and direct binding， thereby reducing the damage caused by secondary bile acids such as DCA to colonic epithelial cells.
