Bisphenols (BPs) are extensively used in food packaging, personal care products, and plastics, making them prevalent in both living and working environments, which has raised significant concern. As endocrine-disrupting chemicals, BPs exert toxic effects on the female reproductive system by binding to estrogen receptors, thereby activating or inhibiting the expression of genes related to reproductive functions, which disrupts the normal function of the endocrine system. This paper reviewed the effects of bisphenol A (BPA), bisphenol S (BPS), and bisphenol F (BPF) on female reproductive function, focusing on three key aspects: the effects on the female reproductive organs, the occurrence of associated reproductive disorders, and the mechanisms of toxicity. Specifically, this review highlighted the effects on ovarian function, uterine morphology and function, and fallopian tube function, as well as their correlation with polycystic ovary syndrome, endometriosis, miscarriage, and eclampsia. Additionally, the toxic mechanisms of BPs exposure were summarized, providing a scientific basis for future research on the impact of BPs on the female reproductive system, as well as for the assessment of potential health risks and the development of preventive measures.

Objective To investigate the protective effects of mitochondrial preconditioning in pericytes(PC)against pulmonary vascular leakage in septic rats.Methods ① 128 specific-pathogen-free SD rats(equal gender,200±20 g)were randomized into:Sham group(postoperative tail vein injection of 0.5 mL saline),Sepsis(Sep)group(CLP+saline),PC group(CLP+untreated PC:106 cells/rat),and Mito-PC group(CLP+PC preconditioned with 2 μg mitochondria/104 cells for 12 h).Assessments included:PC lung colonization(flow cytometry),pulmonary barrier function(Evans blue assay),lung histopathology(HE staining),serum organ injury markers[cTnT(cardiac),urea/creatinine(renal)],and inflammatory cytokines(TNF-α,IL-6).② MSC-derived mitochondria were validated by electron microscopy/flow cytometry;primary retinal PCs from weaned SD rats were purity-verified(confocal microscopy).In vitro groups:Control(PC),Mito-PC,PC+H2O2(0.5 μmol/L,4 h),and Mito-PC+H2O2.Antioxidant capacity was assessed via pentose phosphate pathway(PPP)activity,NADPH levels,G6PD activity,and NADP+/NADPH ratio.Results① Compared with Sham,Sep group showed significant increase in pulmonary leakage(Evans blue P<0.05),severe lung injury,elevated serum markers(TNF-α,IL-6,cTnT,urea,creatinine all P<0.05),0％72 h survival.PC group showed partial improvement(P<0.05).Mito-PC group demonstrated significant reduction in vascular leakage(P<0.05 vs PC group),improved histopathology and organ function(P<0.05),attenuated inflammation(P<0.05),higher 72 h survival rate(P<0.05).② Mitochondrial preconditioning significantly enhanced PPP activation and NADPH-mediated antioxidative capacity,Mito-PC+H2O2 vs PC+H2O2 showed improved cell viability(P<0.05),Mito-PC vs PC showed increased G6PD activity(P<0.05),decreased NADP+/NADPH ratio(P<0.05).Conclusion Mitochondrial preconditioning potentiates pericyte-mediated protection against sepsis-induced pulmonary vascular leakage through enhanced pentose phosphate pathway activity.Mitochondrial preconditioning potentiates pericyte-mediated protection against sepsis-induced pulmonary vascular leakage through enhanced pentose phosphate pathway activity.

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.

BACKGROUND:The risk factors for patellofemoral pain syndrome are still unclear and research on risk factors is gradually becoming a hot topic in order to improve the therapeutic outcome of this disease. OBJECTIVE:To investigate the relationship between lower limb alignment and patellofemoral pain syndrome in young male runners. METHODS:In the same running population,21 patients with bilateral knee pain,29 patients with single knee pain and 20 normal runners were collected from January 2021 to July 2022.Full-length X-ray examination of both lower limbs in standing position was performed in all subjects.The lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,hip-knee-ankle angle,and knee physical valgus angle were measured and statistically analyzed. RESULTS AND CONCLUSION:There was no significant difference in the parameters between the left and right knees in each group(P>0.05).Compared with the normal group,no significant changes in lateral distal femoral angle,medial tibial proximal angle,joint line congruence angle,and hip-knee-ankle angle were observed in the single knee pain group and double knee pain group,while the knee physical valgus angle was significantly increased in these two groups(P<0.05).To conclude,increased knee physical valgus angle may be a risk factor for patellofemoral pain syndrome.

The macrophages,as a crucial component of the body's immune system,can be polarized into M1 and M2 types by different cellular molecules in various environments,and contribute to the progression of various diseases.In inflammatory responses,the M1 macrophages are primarily regarded as the pro-inflammatory cells,facilitate the inflammation progression,tissue destruction,and bone resorption,while M2 macrophages,as inflammatory cells,participate in tissue healing and bone repairment.In the tumor microenvironment,the roles of M1 and M2 macrophages are reversed.The periodontitis,pulpitis,and oral squamous cell carcinoma(OSCC)are the most prevalent inflammation and tumor in the oral cavity.Therefore,this article summarizes the relevant researches from home and abroad on the polarization of macrophages in oral inflammatory responses such as periodontitis,peri-implantitis,and pulpitis,bone remodeling during orthodontic treatment,and OSCC,and elucidate the metabolic activities of macrophages in infiammation,tumor,and bone remodeling and the mechanism of regulating the onset and development of diseases by the macrophage polarization,and provides new perspectives for the clinical treatment.

Objective:To translate the Cumulated Ambulation Score (CAS) into Chinese and test its reliability and validity in elderly inpatients, to provide a basis for assessing elderly inpatients′ basic mobility during hospitalization.Methods:This was a cross-sectional study. After obtaining the authorization of the original author, the Chinese version of CAS was formed by WHO′s cross-cultural translation process. A total of 414 hospitalized elderly inpatients from Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine, and Shanghai Yangpu District Kongjiang Hospital were selected between March and September 2021. Cronbach′s α coefficient was used to test internal consistency, linear weighted Kappa was employed to assess inter-rater reliability, and concurrent validity was examined using items related to mobility of Barthel Index scores as a reference standard.Results:Of the 414 patients, 221 were males and 193 were females, and the patients aged (76.67 ± 9.98) years old; 122 cases (29.5%) had a perfect score of 6 with normal basic mobility, 89 cases (21.5%) had a score of 0 with complete loss of mobility, and the remaining 203 patients had a score of 1-5 with varying degrees of reduced mobility. The Chinese version of CAS demonstrated good assessment performance for basic mobility in elderly inpatients with a Cronbach′s α coefficient of 0.952. Weighted Kappa values for individual items and total scores showed excellent agreement among raters (>0.85), while concurrent validity yielded a value of 0.935 ( P<0.01) when compared with Barthel Index scores.Total score of CAS was significantly correlated with item scores and total score of Barthel index ( r values were 0.423 to 0.944, all P<0.01). Conclusions:The Chinese version of CAS has good reliability and validity. The items are concise, clear and easy to understand. It is suitable as a preliminary screening tool for clinical departments to evaluate the basic mobility of elderly inpatients.

Dopamine D₃ receptor (D₃R) is implicated in multiple psychotic symptoms. Increasing the D₃R selectivity over dopamine D₂ receptor (D₂R) would facilitate the antipsychotic treatments. Herein, novel carbazole and tetrahydro-carboline derivatives were reported as D₃R selective ligands. Through a structure-based virtual screen, ZLG-25 (D₃R K_i = 685 nmol/L; D₂R K_i > 10,000 nmol/L) was identified as a novel D₃R selective bitopic ligand with a carbazole scaffold. Scaffolds hopping led to the discovery of novel D₃R-selective analogs with tetrahydro-β-carboline or tetrahydro-γ-carboline core. Further functional studies showed that most derivatives acted as hD₃R-selective antagonists. Several lead compounds could dose-dependently inhibit the MK-801-induced hyperactivity. Additional investigation revealed that 23j and 36b could decrease the apomorphine-induced climbing without cataleptic reaction. Furthermore, 36b demonstrated unusual antidepressant-like activity in the forced swimming tests and the tail suspension tests, and alleviated the MK-801-induced disruption of novel object recognition in mice. Additionally, preliminary studies confirmed the favorable PK/PD profiles, no weight gain and limited serum prolactin levels in mice. These results revealed that 36b provided potential opportunities to new antipsychotic drugs with the multiple antipsychotic-like properties.

Objective To observe the effect of acanthopanax refined polysaccharide(ASPS)on nicotine-induced learning and memory impairment in mice.Methods A total of 48 male mice and 48 females at 6 weeks of age were selected and were divided into two batches for animal experiments:the Morris and the new object recognition batch.Each batch was randomly divided into 6 groups ac-cording to body weight:blank control group,model group,drug positive group,high-dose ASPS group,medium-dose ASPS group,and low-dose ASPS group.Except for the blank group,the remai-ning 5 groups were injected subcutaneously with 0.5mg/kg of nicotine every day for 7 days to prepare a nicotine memory disorder model.After 24 hours of injection of nicotine at the 7th day,the drug posi-tive group was gavaged piracetam for 800 mg/kg,and the high-dose,medium-dose and low-dose ASPS groups were gavaged for 270,90 and 30 mg/kg of ASPS respectively for 7 days.The learning and memory ability of mice was detected by water maze test and new object recognition test,respec-tively.After the two tests,superoxide dismutase(SOD)activity in serum and 5-Hydroxytryptamine(5-HT)content in hippocampal tissue were detected.Results The results of new object recognition experiment showed that the discrimination indexes of the high-,medium-and low-dose ASPS groups were significantly higher than that of the model group(P＜0.01 or P＜0.05).The results of water maze experiment showed that the time to find the platform in the spatial search experiment was signifi-cantly shorter in the high-and medium-dose ASPS groups than that in the model group(P＜0.05).In the positioning voyage test,the number of mouse platform entries in the high-dose ASPS group was significantly more than that in the model group(P＜0.05);the proportions of Ⅲ quadrant routes in the high-and medium-dose ASPS groups were higher than those in the model group(P＜0.05).The high-,medium-and low-dose ASPS groups were significantly higher than those in the model group(P＜0.01);the determination of hippocampal tissue content in mice showed that the content of 5-HT in the high-and medium-dose ASPS groups was significantly higher than that in the model group(P＜0.01 or P＜0.05).Conclusion ASPS can significantly improve the learning and memory ability of nicotine-quitting mice,relieve the damage of hippocampal neurotransmitters,and regulate oxidative stress in vivo.The mechanism may be related to improving the body's antioxidant capacity and regulating hippocampal neurotransmitter levels.

OBJECTIVE To investigate the protective effects and mechanism of ziyuglycoside Ⅰ on acute lung injury in sepsis rats based on network pharmacology， and conduct experimental verification. METHODS The network pharmacology was used to predict the potential target of ziyuglycoside Ⅰ in the treatment of acute lung injury following sepsis. The rat model of sepsis was reproduced by cecum ligation and puncture for experimental verification. Totally 192 SD rats were randomly divided into the sham operation group （Sham group）， sepsis group （Sep group）， conventional therapy group （CT group） and ziyuglycoside Ⅰ group （Zg Ⅰ group）， respectively. Sham group and Sep group were given sterile normal saline， and CT group and ZgⅠ group were given relevant volume of Ringer’s solution and ziyuglycoside Ⅰ. The arterial blood gas， serum inflammatory factors， lung wet/dry mass ratio， pathological changes of lung tissue， pulmonary vascular permeability， the expressions of pulmonary vein tight junction protein 1 （ZO-1） and vascular endothelial cadherin （VE-cadherin） protein and 72-hour survival were observed in each group. RESULTS Results of network pharmacology showed that there were 47 potential targets of ziyuglycoside Ⅰ in the treatment of sepsis. The results of gene ontology function enrichment analysis and Kyoto encyclopedia of genes and genomes pathway enrichment analysis showed that the mechanism could 598486924@qq.com be correlated with biological processes such as positive regulation of reactive oxygen species metabolism， wound healing， regulation of endothelial cell proliferation， cell activation， blood vessel development， response to oxidative stress， etc.， and with signaling pathway such as apoptosis， tight junction， HIF-1 signaling pathway， etc. The results of experimental verification showed that compared with Sham group， pH value and the level of partial arterial oxygen pressure were decreased significantly in Sep group （P＜0.05）， while the level of partial pressure of carbon dioxide， serum levels of tumor necrosis factor α， interleukin 6 were increased significantly （P＜0.05）； the ratio of lung wet/dry mass was increased significantly （P＜0.05）； the protein expressions of ZO-1 and VE-cadherin were decreased significantly （P＜0.05）； 72 h survival rate decreased，the survival time was significantly shortened （P＜0.05）； the results of pathological observation of lung tissue showed that the rats’ alveoli were extensively ruptured， the alveolar wall was thickened and accompanied with edema， and there was obvious inflammatory cell infiltration； the results of pulmonary vascular permeability observation showed that the lung surface of rats was dark， with a large amount of Evans blue exudation， and the left lower lung was obviously dark blue. Compared with Sep group， the levels of above indexes almost were reversed significantly in CT group and ZgⅠ group （P＜0.05）； the lung histopathology and pulmonary vascular permeability were significantly improved， and the recovery degree of ZgⅠ group was greater than that of CT group， which was close to the results of Sham group. CONCLUSIONS Ziyuglycoside Ⅰ can significantly reduce inflammatory reaction and acute lung injury in septic rats， which is related to vascular function and tight junction signal pathway.
