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.

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.

ObjectiveTo investigate the pharmacodynamic effects of Houshihei San （HSHS） recorded with the effects of treating wind and limb heaviness on muscle tissue injury after middle cerebral artery occlusion （MCAO） in rats through the ferroptosis pathway. MethodsThirty SD male rats were selected and randomly grouped as follows： sham， MCAO， deferoxamine mesylate， high-dose HSHS （HSHS-H， 0.54 g·kg^-1）， and low-dose HSHS （HSHS-L， 0.27 g·kg^-1）， with 6 rats in each group. A laser scattering system was used to evaluate the stability of the MCAO model， and rats were administrated with corresponding agents by gavage for 7 days. During the administration period， behavioral， imaging and other methods were used to systematically evaluate the skeletal muscle tissue injury after MCAO and the therapeutic effect in each administration group. Hematoxylin-eosin staining was employed to evaluate the cross-section of muscle cells. Subsequently， immunohistochemistry was used to detect tumor suppressor p53 and glutathione peroxidase 4 （GPX4） in the soleus tissue. Western blot was employed to determine the protein levels of p53， GPX4， myogenic differentiation 1 （MyoD1）， nuclear factor E₂-related factor 2 （Nrf2）， Myostatin， solute carrier family 7 member 11 （SLC7A11）， muscle ring-finger protein-1 （MuRF1）， and muscle atrophy F-box protein （MAFbx） to verify the therapeutic effect in each group. ResultsCompared with the MCAO group， HSHS enhanced the locomotor ability and promoted muscle regeneration， which suggested that the pharmacological effects of HSHS were related to the inhibition of muscle tissue ferroptosis to reduce the expression of muscle atrophy factors. Behavioral and imaging results suggested that compared with the MCAO group， HSHS ameliorated neurological impairments in rats on day 7 （P<0.01）， enhanced 5-min locomotor distance and postural control （P<0.01）， strengthened grasping power and promoted muscle growth （P<0.01）， stabilized skeletal muscle length and weight （P<0.01）， and increased the cross-section of muscle cells （P<0.01）. Compared with the MCAO group， HSHS promoted the increases in glutathione and superoxide dismutase content and inhibited the increase in malondialdehyde content （P<0.05，P<0.01）. Ferroptosis pathway-related assays suggested that HSHS reduced the p53-positive cells and increased the GPX4-positive cells （P<0.01）. HSHS ameliorated muscle function decline after stroke by promoting the expression of GPX4， Nrf2， SLC7A11， and MyoD1 and inhibiting the expression of p53， Myostatin， MurRF1， and MAFbx to reduce ferroptosis in the muscle （P<0.01）. ConclusionHSHS， prepared with reference to the method in the Synopsis of Golden Chamber， can simultaneously reduce the myolysis and increase the protein synthesis in the skeletal muscle tissue after ischemic stroke by regulating the ferroptosis pathway.

Objective:To analyze the effect of different doses of estrogen on endometrial blood flow after tran-scervical resection of adhesion(TCRA)surgery in patients with intrauterine adhesion(IUA).Methods:A total of 70 moderate and severe IUA patients who underwent TCRA in the General Hospital of Ningxia Medical University from 2021 to 2023 were divided into group A(4 mg/day)and group B(6 mg/day)according to the dosage of es-trogen after operation.Reexamination of hysteroscopy was performed 2 months later,menstrual volume was fol-lowed up,uterine parameters in secretory phase were detected by B-ultrasound,and factors related to prolifera-tion,fibrosis and blood flow were detected by immunofluorescence after 3 months.Results:① In the severe IUA group,there was no difference in the rate of intrauterine re adhesion between group A2 and group B2.The satis-faction rate of endometrial epithelialization and endometrial glandular duct density in group B2 was higher than that in group A2,and the difference was statistically significant(P＜0.05).There was no significant difference in the three indicators within the moderate IUA group(P＞0.05).②Three months after operation,in the severe IUA group,there were statistically significant differences(P＜0.05)in menstrual flow,endometrial thickness ET,endo-metrial volume EV,endometrial blood flow values(VI,FI,VFI),and uterine artery blood flow values(PI,RI)be-tween the two groups;The above indicators showed no statistically significant differences within the moderate IUA group(P＞0.05).③Detection of endometrial markers:the expression of proliferation marker(Ki-67)and angio-genesis marker(CD31,CD34,CD146,b-FGF,VEGF)in group B2 was higher than that in group A2,while the ex-pression of fibrosis marker(α-SMA,TGF-β1)was lower,with statistical significance(P＜0.05).There was no sig-nificant difference in the expression of above indexes between group A,and group B,in moderate IUA group(P＞0.05).Conclusions:Short-term application of relatively high dose estrogen(6 mg/day)after TCRA can pro-mote better endometrial repair by improving endometrial blood flow in patients with severe IUA,while in patients with moderate IUA there is no significant difference in the effect on endometrial repair.

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.

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.
