Objective Based on the"preventive treatment of disease"theory and real-world data,this study aimed to evaluate the clinical efficacy of Yangyin Shugan Formula in patients with ovarian dysfunction characterized by the syndrome of kidney deficiency and liver depression at different stages and to provide evidence for optimizing the timing of traditional Chinese medicine(TCM)in premature ovarian insufficiency(POI)management.Methods Ovarian dysfunction patients under 40 years old characterized by syndrome of kidney deficiency and liver depression,registered in the outpatient electronic medical records of the Second Affiliated Hospital of Guangzhou University of Chinese Medicine from January 2020 to December 2023,were stratified into three groups:subclinical POI,POI,and premature ovarian failure(POF)groups.The therapeutic outcomes of the three groups of patients were compared,including TCM syndrome total response rates,menstrual total response rates/normalization(cured)rates,base follicle-stimulating hormone(FSH)total response rate/normalization rates and anti-Müllerian hormone(AMH)levels.Results A total of 307 patients meeting the research criteria were included(97 cases in subclinical POI group,112 cases in POI group,and 98 cases in POF group).The TCM syndrome total response rates ranked as subclinical POI group(98.97%,96/97)>POI group(95.54%,107/112)>POF group(83.67%,82/98),with the POF group was lower than that of the subclinical POI and POI groups(P<0.017);while the difference of the subclinical POI group with the POI group was not significant.Menstrual total response rates ranked as subclinical POI group(97.22%,70/72)>POI group(72.32%,81/112)>POF group(51.02%,50/98),the differences among the three groups and in the post-hoc comparisons were significant(P<0.01,P<0.017);normalization rates ranked as subclinical POI group(90.28%,65/72)>POI group(54.46%,61/112)>POF group(26.53%,26/98),the differences among the three groups and in the post-hoc comparisons were significant(P<0.01,P<0.017).FSH total response rates ranked as subclinical POI group(89.69%,87/97)>POI group(81.25%,91/112)>POF group(60.20%,59/98),while POF group was lower than that of the other two groups(P<0.017),and the difference of the subclinical POI group with the POI group was not significant.Normalization FSH rates ranked as subclinical POI group(71.13%,69/97)>POI group(53.57%,60/112)>POF group(16.33%,16/98),the differences among the three groups and in the post-hoc comparisons were significant(P<0.01,P<0.017).Compared with before treatment,the FSH levels in all three groups decreased after treatment(P<0.01).The reduction of FSH in the POF and POI groups were better than that in the subclinical P OI group(P<0.017).No significant difference was observed in the reduction of FSH between the POI and POF groups.Post-treatment AMH elevation observed in the subclinical POI and POI groups(P<0.01).Conclusion Yangyin Shugan Formula improves the menstrual conditions and TCM syndromes across all the stages.It also improves elevated FSH levels across all the stages and has a specific effect on normalizing FSH and menstruation.Yangyin Shugan Formula increases the AMH levels of patients with subclinical POI and POI,highlighting the applicability of TCM in staged preventive management.

Objective: To investigate the correlation of chemerin levels in the serum and intestinal mucosal with in- testinal mucosal inflammation in IBS-D mice . Methods: A total of 128 female C57BL/6J mice were randomly di- vided into IBS-D group and control group , with 64 mice in each group . Wire Restraint Stress method (WRS) was used to construct an animal model of IBS-D . Enzyme-linked immunosorbent assay was used to detect serum and co- lonic mucosal chemerin levels in mice . Hematoxylin-eosin (HE) staining was used to observe colonic mucosal in- flammation . Geboes value was used to evaluate the severity of colonic mucosal inflammation . Results: In the IBS- D group , the concentration of serum chemerin increased and reached the peak in the first week of the experiment ( t = 6. 538 , P < 0. 001) , and the concentration of colonic mucosa chemerin increased and reached the peak in the fourth week of the experiment ( t = 8 . 104 , P < 0. 001) ; in the first week of experiment , the colonic mucosa of IBS- D mice showed inflammatory reaction , which was the most significant in the fifth week (P < 0. 05) . Geboes score was ( 1 . 75 ±0. 50) vs (0. 55 ±0. 52) . Conclusion There is a temporal sequence between the elevation of serum and intestinal mucosal chemerin levels and the severity of intestinal mucosal inflammation , and it is hypothesized that the elevated serum and intestinal mucosal chemerin levels correlate with the onset and progression of intestinal mucosal inflammation .

ObjectiveTo explore the key molecules regulated by norcantharidin (NCTD) in colon cancer treatment.MethodsWe used cell counting kit-8 and 5-ethnyl-2′-deoxyuridine/Hoechst staining assays to study the effects of NCTD on cell proliferation in colon cancer. Annexin V-fluorescein isothiocyanate/propidium iodide staining was used to evaluate apoptosis, whereas Transwell assays were conducted to evaluate migration and invasion. We performed RNA sequencing to analyze the changes in gene expression after treatment. Differential analysis was performed using differential expression sequencing 2 (Deseq2) in R. Cytoscape was used to construct a competing endogenous RNA (ceRNA) network and Gene Expression Omnibus (GEO) datasets were used to validate sine oculis homeobox homolog 4 (SIX4) expression in colon cancer tissues. Furthermore, the prognostic potential of SIX4 was evaluated using receiver-operating characteristic curves. We conducted an immune infiltration analysis to explore the SIX4 relationship with the immune microenvironment in colon cancer. Finally, SIX4 expression, pan-cancer prognosis, tumor mutation burden (TMB) correlations, microsatellite instability (MSI), and mismatch repair (MMR) were analyzed.ResultsNCTD inhibited colon cancer cell proliferation (P .0001), induced apoptosis (P = .0007), and suppressed the migration and invasion of colon cancer cells. The H19/miR-193b-3p/SIX4 axis was identified as the key ceRNA network involved in the anticancer activity of NCTD. SIX4 is highly expressed in colon cancer tissues, shortening patient survival and affecting immune infiltration. A pan-cancer analysis showed that SIX4 overexpression affects the survival of various cancers. Finally, we correlated SIX4 expression with TMB, MSI, and MMR expression.ConclusionNCTD inhibits the malignant behaviour of colon cancer cells. SIX4 is abnormally expressed in multiple tumor types, significantly affecting the overall survival of patients with cancer, and is a core regulatory target of NCTD in the treatment of colon cancer.

Objective:To understand the incidence of adverse pregnancy outcome in HIV-infected pregnant women and influencing factors in China and provide reference for the improvement of the health status of HIV-infected pregnant women and their newborns.Methods:Based on a mother-child cohort of HIV-infected pregnant women and children (PMTCT-MC-2005) established in Guangxi Zhuang Autonomous Region, Yunnan Province and Xinjiang Uygur Autonomous Region, this study enrolled pregnant women with or without HIV infection as study subjects from January 2017 to June 2023, a total of 1 646 pregnant women (558 HIV-infected and 1 088 HIV-uninfected) were included, and 34 cases with missing data were excluded. The χ2 test was used to analyze the difference in the incidence adverse pregnancy outcome between two groups, and used logistic regression model to identify the influencing factors of adverse pregnancy outcome in HIV-infected pregnant women. Results:A total of 1 612 pregnant women were included in the study, in whom 541 were infected with HIV and 1 071 were not infected with HIV. The incidence of adverse pregnancy outcome was 18.8% (303/1 612), the incidence of adverse pregnancy outcome was 33.1% (179/541) in the HIV-infected pregnant women and 11.6% (124/1 071) in the pregnant women without HIV infection. The results of multivariable logistic regression analysis showed that the influencing factors of adverse pregnancy outcome were age <35 years at delivery (a OR=0.64, 95% CI: 0.43-0.95) compared with the age ≥35 years and the duration of antiviral treatment over 10 years (a OR=0.43, 95% CI: 0.23-0.79) compared with less than one year. Conclusions:The incidence of adverse pregnancy outcome in HIV-infected pregnant women was high in some regions of China during 2017-2023. It is necessary for HIV-infected women to get pregnancy at appropriate time based on antiretroviral treatment effect and strengthen self-care to reduce the incidence of adverse pregnancy outcome.

Objective:To explore the molecular mechanism of miR-4508 regulating the inflammatory response of human bronchial epithelial cells induced by representative chrysotile asbestos.Methods:The chrysotile asbestos was ground into ultrafine dust using a horizontal planetary instrument, and human bronchial epithelium (16HBE) cells were taken as the object of infection. Cell survival rate was detected by cell counting kit-8 method, cytotoxicity was detected by lactate dehydrogenase (LDH) kit. The released of inflammatory factor IL-6 was detected by electrochemical luminescence. The released inflammatory factor IL-8 was detected by enzyme-linked immunosorbent assay. The expression level of miR-4508 was screened and verified by reverse transcription-quantitative real-time polymerase chain reaction. After 16HBE cells were treated with AKT inhibitor MK2206, the phosphorylation levels of AKT and PTEN were detected by western blot. The expression levels of AKT and PTEN and the contents of IL-6 and IL-8 were detected in miR-4508 overexpression and interference experiments.Results:With the increase of chrysotile asbestos exposure concentration, the cell survival rate decreased in a concentration-dependent manner, and the LDH content gradually increased. The secretion of IL-6 and IL-8 in chrysotile 25, 50 and 75 μg/ml groups were (325.92±8.61) pg/ml, (331.51±4.96) pg/ml, (378.74±13.77) pg/ml, and (94.95±3.11) pg/ml, (357.60±1.80) pg/ml, (537.19±3.11) pg/ml, respectively, while the group with 0 μg/ml chrysotile was (95.85±1.20) pg/ml and (7.81±0.00) pg/ml ( P＜0.05). In addition, chrysotile asbestos exposure to 16HBE could induce the high expression of miR-4508 . After pretreatment with MK2206, the phosphorylation levels of AKT and PTEN were decreased, the contents of IL-6 and IL-8 were significantly decreased, and the expression level of miR-4508 was significantly reduced. Overexpression of miR-4508 significantly increased the expressions of AKT and PTEN, and the contents of IL-6 and IL-8 ( P＜0.01). After interfering with miR-4508, the expressions of AKT and PTEN were significantly decreased, and the contents of IL-6 and IL-8 were significantly decreased ( P＜0.01). Conclusions:Chrysotile asbestos can induce the inflammatory response of 16HBE cells and up-regulate the expression level of miR-4508. The up-regulation of miR-4508 promotes the 16HBE inflammatory response induced by chrysotile asbestos through the PI3K/AKT pathway.

Objective To investigate the antioxidant activity of bamboo stem extracts and the therapeutic effect of bamboo stem water extract on oxidative inflammation induced by tert butyl hydroperoxide (t-BHP) in human colon adenocarcinoma cells (Caco-2). Methods In this study, ABTS, DPPH, and FRAP assays were used to determine the extracellular antioxidant activity of petroleum ether extract, ethyl acetate extract, n-butanol extract, 95% ethanol extract, and distilled water extract from bamboo stems. The human intestinal Caco-2 cell line was used as the model cell, and t-BHP was selected as the oxidative stress modeling agent. The CCK-8 assay was used to detect cell viability and the optimal oxidative damage concentration of t-BHP. The content of MDA, 8-OHdG, TNF-α and IL-1β were detected to assess antioxidant stress effect. Results The five extracts of bamboo all had certain antioxidant activity, among which the water extract of bamboo stem had the best comprehensive antioxidant activity with high cell viability in Caco-2 cells. The optimal modeling concentration of t-BHP was 200 μMol/L. The water extract of bamboo stem significantly reduced the content of oxidative stress related biomarkers and inflammatory factors in Caco-2 cells induced by t-BHP. Conclusion The stem extracts of bamboo in Xianning City have strong in vitro antioxidant activity. Among them, the water extract of bamboo stem has a protective effect on t-BHP induced oxidative damage in Caco-2 cells, suggesting that the water extract possesses a potential to be developed as new antioxidant products for clinical prevention and treatment of oxidative damage related diseases.

AIM: To explore the relationship of miR-126 and miR-325 in serum and vitreous with the severity of proliferative vitreoretinopathy(PVR).METHODS: A total of 100 cases(100 eyes)with PVR who were treated in our hospital from October 2019 to October 2022 were selected and retrospectively studied. They were divided into a mild group(42 eyes)and a severe group(58 eyes)according to the degree of retinopathy, and another 30 cases(30 eyes)that underwent vitrectomy without retinopathy due to eye trauma in our hospital during the same period were selected as the control group. Fluorescence quantitative PCR was used to detect the expression levels of miR-126 and miR-325 in serum and vitreous; ELISA was used to detect the levels of transforming growth factor β(TGF-β), platelet-derived growth factor(PDGF), vascular endothelial growth factor(VEGF), and tumor necrosis factor α(TNF-α)in serum and vitreous; and Pearson's method was used to analyze the correlation between the serum and vitreous levels of miR-126 and miR-325 correlated with the levels of TGF-β, PDGF, VEGF, and TNF-α; Logistic multifactorial analysis was used to analyze the influencing factors for the occurrence of severe PVR.RESULTS: Compared with the control group, miR-126 levels in serum and vitreous of PVR patients were decreased and lower in the severe PVR group than in the mild PVR group(both P<0.05); miR-325 levels were increased and higher in the severe PVR group than in the mild PVR group(both P<0.05). TGF-β, PDGF, VEGF, and TNF-α levels in serum and vitreous were increased in the severe PVR group compared to the mild PVR group(all P<0.05). The miR-126 levels in serum and vitreous of patients with PVR were negatively correlated with miR-325, TGF-β, VEGF, TNF-α, and PDGF levels(all P<0.05), and miR-325 was positively correlated with TGF-β, VEGF, TNF-α, and PDGF levels(all P<0.05). Logistic regression analysis showed that miR-325, TGF-β, PDGF, and TNF-α were all independent risk factors for the development of severe PVR in serum and vitreous, and miR-126 was an independent protective factor for the development of severe PVR in serum and vitreous(P<0.05).CONCLUSION: With the aggravation of PVR, miR-126 expression in serum and vitreous decreased while miR-325 expression increased and correlated with TGF-β, TNF-α, VEGF, and PDGF.
