OBJECTIVE To investigate the effects of ω-3 polyunsaturated fatty acid (ω-3PUFA) combined with clomiphene on clinical efficacy, pregnancy and safety in patients with polycystic ovary syndrome (PCOS). METHODS A retrospective analysis was performed on the clinical data of 112 PCOS patients who received treatment in Dept. of Obstetrics and Gynecology of Hunan Prevention and Treatment Institute for Occupational Diseases from January 2022 to December 2023. According to the different treatment regimens, the patients were divided into single-drug group (60 cases) and drug-combination group (52 cases). Single-drug group was given clomiphene orally, and drug-combination group was given clomiphene+ω-3PUFA. Clinical efficacy, pregnancy status and the occurrence of adverse drug reaction (ADR) as well as ovarian function and oxidative stress indexes before and after treatment were compared between 2 groups. RESULTS The overall response rate (90.38% vs. 71.67%), ovulation rate (84.62% vs. 61.67%), and pregnancy rate (51.92% vs. 26.67%) were all markedly higher in drug combination group than single drug group ( P <0.05). Before treatment, there was no statistical significance in ovarian function and oxidative stress indexes between 2 groups ( P >0.05). Compared with before treatment, serum anti-Müllerian hormone levels, inhibin B concentr ations, and the number of cystic follicles in 2 groups were decreased significantly after 12 weeks of treatment ( P <0.05). The endometrial thickness increased significantly ( P <0.05), while the serum levels of malondialdehyde and advanced oxidation protein products decreased significantly ( P <0.05); the activities of serum superoxide dismutase and glutathione peroxidase increased significantly ( P <0.05); the improvement of drug combination group was significantly better than single drug group ( P <0.05). The ovarian volumes in both groups were significantly smaller after treatment compared to before treatment ( P <0.05), but there was no statistically significant difference between the two groups ( P >0.05). There was no significant difference in the overall incidence of ADR between the two groups during the treatment ( P >0.05). CONCLUSIONS The combination of ω-3PUFA and clomiphene has a definite therapeutic effect on PCOS, which can effectively reduce the body’s oxidative stress response, improve ovarian function, and increase ovulation and pregnancy rates.

Background/Aims:
Biliary tract cancer (BTC) frequently harbors KRAS mutations, which are associated with resistance to traditional treatment and a poor prognosis. Synthetic lethality (SL) strategy may provide other targets of KRAS. Therefore, we aim to identify and validate potential therapeutic targets of KRAS for the treatment of BTC via SL.
Methods:
The dependency (DepMap) projects were used to predict the synthetic lethal gene of KRAS. FDA-approved anticancer drug library was applied to screen potential drugs effective against KRAS-mutant BTC. Furthermore, the synthetic lethal effects or corresponding mechanisms of potential genes and drugs on BTC were investigated using KRAS-mutant and KRAS-wild type BTC cell lines, patient-derived xenografts (PDX), and KRAS oncogene-driven tumor models, as well as other KRAS-mutant cancer cell lines.
Results:
Initially, we discovered that the loss of GATA2 reduced the viability of KRAS-mutant but not KRAS-wild-type BTC. Subsequently, the drug library screened out disulfiram, which primarily exerts a synthetic lethal effect by inhibiting interleukin-1β (IL-1β) in KRAS-mutant BTC. Mechanistically, GATA2 specifically enhanced the transcription of IL-1β to promote NF-κB signaling in KRAS-mutant BTC. IL-1β inhibition phenocopied GATA2 deficiency, leading to reduced KRAS-mutant BTC viability. These synthetically lethal effects were confirmed using PDX, a KRAS oncogene-driven tumor model, as well as in other KRAS-mutant cancer cell lines.
Conclusions
In summary, these results indicate that inhibiting GATA2/IL1β could be a therapeutic strategy in KRAS-mutant BTC and potentially other cancers.

Objective Exploring genetic differences among geographic strains of Anopheles sinensis in China. Methods Based on the mitochondrial cytochrome oxidase subunit I(COⅠ )and ribosomal the second internal transcribed spacer(ITS2), genetic distance analyses were conducted on An. sinensis samples collected nationwide. Results Genetic differentiation was observed within An. sinensis geographic strains, primarily reflected in the genetic distances of COⅠ sequences, with some distances between samples exceeding those between closely related species. However, ITS2 sequences showed relatively low levels of differentiation within geographic strains. No significant separation was observed, and gene exchange exhibited a random pattern among geographic strains. Conclusions Significant differences in genetic distance were observed among An. sinensis samples, along with evidence of interspecific continuity among sibling species. For the identification of closely related species using wild-collected Anopheles mosquitoes samples, reliance solely on commonly used barcodes such as COⅠ and ITS2 may be insufficient. Additional molecular markers, including COⅡ and D3 gene fragments, should also be considered. Caution should be exercised when using COⅠ genes to identify cryptic species, especially within Anopheles mosquitoes.

Objective To investigate the effects and related mechanisms of mitochondrial-derived peptide MOTS-c on glycochenodeoxycholic acid (GCDCA)-induced injury in human hepatocytes (THLE-3 cells). Methods THLE-3 cells were cultured in vitro and treated with different concentrations of GCDCA and MOTS-c. The optimal concentrations of GCDCA and MOTS-c were determined by cell counting kit (CCK)-8 method. Subsequently, THLE-3 cells were treated or pre-treated with GCDCA (200 µmol/L), MOTS-c (15, 30, 60 µmol/L), the multidrug resistance protein 2 (MRP2) inhibitor Probenecid (500 µmol/L), and the nuclear factor erythroid 2-related factor 2 (Nrf2) inhibitor ML385 (10 µmol/L). Cell proliferation was assessed by CCK-8 method. Lactate dehydrogenase (LDH) levels in the culture medium were measured by biochemical method. Cell apoptosis rates were determined by flow cytometry. MRP2 messenger RNA (mRNA) levels were detected by real-time quantitative polymerase chain reaction (RT-qPCR). MRP2 and Nrf2 protein expression levels were analyzed by Western blotting. Results As the concentration of GCDCA increased, the proliferation activity of THLE-3 cells gradually decreased, while LDH activity in the culture medium and apoptosis levels increased, and the expression levels of MRP2 in the cells decreased (all P<0.05). Treatment with 30 and 60 µmol/L MOTS-c significantly enhanced the proliferation activity of THLE-3 cells exposed to GCDCA, upregulated the expression of MRP2 and Nrf2, and reduced LDH activity and apoptosis levels (all P<0.05). Co-treatment with Probenecid partially reversed the protective effects of MOTS-c on GCDCA-induced THLE-3 cells injury, while co-treatment with ML385 partially inhibited the induction of MRP2 expression by MOTS-c in THLE-3 cells exposed to GCDCA. Conclusions MOTS-c may alleviate GCDCA-induced injury in human hepatocytes (THLE-3 cells), and its mechanism may be related to the upregulation of MRP2 expression mediated by Nrf2.

Sarin(GB)is a typical representative of nerve agents with high toxicity,and very low amount can cause death.GB can cause water and atmospheric environment poisoning,so the detection of GB in water and air is of great significance.In this work,a colorimetric sensor array(CSA)based on GB inhibition of cholinesterase activity was constructed to detect GB with high selectivity.A 4×4 colorimetric array was constructed using acetylcholinesterase(AChE),butyryl cholinesterase(BuChE)and the corresponding substrate acetylthiocholine iodide(S-ACh),butyryl thiocholine iodide(S-BCh),acetylcholine chloride(ACh),butyryl choline chloride(BCh)and 2,6-dichloroindophenol ethyl ester(DCIE).The linear curve of the sensor was Y=131.3×lgC+271.6(R2=0.997),where Y was the array response Euclidean distance,C was the concentration of GB(mg/L),the linear range was 0.03?0.32 mg/L,and the detection limit was 27.6 μg/L.The method could effectively distinguish chemical warfare agents(CWA)such as VX,Soman(GD),mustard gas(HD),Louie reagent(L),and had high anti-interference ability,sensitivity and good repeatability.It was successfully applied to the detection of GB in simulated water and simulated air samples,and the sample recovery rate was 97.2% ?100.9%.This method would be potentially applied to the field rapid detection of nerve agents.

Objective:To explore the association between cardiometabolic multimorbidity(CMM), the number of cardiometabolic diseases(CMD)and mild cognitive impairment(MCI)among the older adults in urban communities.Methods:Based on the baseline data of the Hubei Memory and Aging Cohort Study(HMACS)from 2018 to 2023, CMM was defined as the coexistence of two or more CMDs(Type 2 diabetes, stroke and ischemic heart disease). Multivariate logistic regression was employed to examine the association between CMM, the number of CMDs and the prevalence of MCI, as well as subgroup heterogeneity.Results:This study included 6 113 urban participants aged ≥65 years(55.6% were female; mean age 71.9±5.7 years). The prevalence of MCI was 19.3%, with an increasing trend observed as the number of CMD increased(17.7%, 20.5%, 24.6%, 28.3%). After adjusting for all variables, a significant association was observed between CMM group and the prevalence of MCI( OR: 1.24, 95% CI: 1.01-1.52)compared with the non-CMM group.As the number of CMD increased, the prevalence of MCI increased( Ptrend=0.011), but the association was only significant in the group with two CMDs.Subgroup analyses revealed that in males( OR: 1.48, 95% CI: 1.10-2.00), those with more than 9 years of education( OR: 1.52, 95% CI: 1.15-2.02), and those with hypertension( OR: 1.33, 95% CI: 1.05-1.67), CMM was significantly associated with MCI, and the association with MCI increased significantly with the increase in the number of CMDs(all Pfor trend <0.05). Conclusions:Among urban community-dwelling older adults aged ≥65 years in China, CMM and the cumulative number of CMDs are significantly associated with an increase of MCI, particularly in males, those with higher education levels, and those with hypertension.In the future, the need for enhanced MCI screening for CMM patients should be strengthened, and targeted prevention and control of cognitive impairment should be implemented for high-risk populations.

OBJECTIVE:
Resveratrol (Res) is a promising anticancer drug against hepatocellular carcinoma (HCC), but whether its anti-HCC effects implicate mitophagy remains unclear. Therefore, we aimed to explore the specific role of Res in mitophagy and the related mechanisms during the treatment of HCC.
METHODS:
HepG2 cells and tumor-grafted nude mice were used to investigate the effects of low-, middle- and high-dose of Res on HCC progression and mitophagy in vitro and in vivo, respectively. A series of approaches including cell counting kit-8, flow cytometry, wound healing and transwell assays were used to evaluate tumor cell functions. Transmission electron microscopy, immunofluorescence and Western blotting were used to assess mitophagy. Mitochondrial oxygen consumption rate, reactive oxygen species and membrane potential were used to reflect mitochondrial function. After disrupting the expression of metastasis-associated lung adenocarcinoma transcript 1 (MALAT1), miR-143-3p, and ribonucleoside reductase M2 (RRM2), the effects of the MALAT1/miR-143-3p/RRM2 axis on cell function and mitophagy under Res treatment were explored in vitro. Additionally, dual-luciferase reporter and chromatin immunoprecipitation were used to confirm interactions between target genes.
RESULTS:
Res significantly inhibited the proliferation and promoted apoptosis of HCC cells in vitro, while significantly suppressing tumor growth in a dose-dependent manner and inducing mitophagy and mitochondrial dysfunction in vivo. Interestingly, MALAT1 was highly expressed in HCC cells and its knockdown upregulated miR-143-3p expression in HCC cells, which subsequently inhibited RRM2 expression. Furthermore, in nude mice grafted with HCC tumors and treated with Res, the expression of MALAT1, miR-143-3p and RRM2 were altered significantly. In vitro data further supported the targeted binding relationships between MALAT1 and miR-143-3p and between miR-143-3p and RRM2. Therefore, a series of cell-based experiments were carried out to study the mechanism of the MALAT1/miR-143-3p/RRM2 axis involved in mitophagy and HCC; these experiments revealed that MALAT1 knockdown, miR-143-3p mimic and RRM silencing potentiated the antitumor effects of Res and its activation of mitophagy.
CONCLUSION
Res facilitated mitophagy in HCC and exerted anti-cancer effects by targeting the MALAT1/miR-143-3p/RRM2 axis. Please cite this article as: Feng CY, Cai CS, Shi XQ, Zhang ZJ, Su D, Qiu YQ.

Ovarian cancer,as one of the three major malignant tumors in gynecology,has a relatively high mortality rate.Traditional adjuvant chemotherapy has failed to significantly improve the survival rate of patients in the advanced stage due to its high drug resistance.Therefore,new treatment methods are urgently needed to improve the survival rate of patients.Cuproposis is a newly proposed form of cell death,which is caused by the accumulation of lipoylated protein and the loss of Fe-S cluster protein by copper overload,and it is expected to be a new treatment method for ovarian cancer to improve the prognosis of patients.Previous studies have shown that cuproptosis related genes are differentially expressed in ovarian cancer,which can guide personalized immunotherapy and participate in chemotherapy resistance.This article will review the correlation between the mechanisms related to cuproptosis and ovarian cancer,and explore whether it can provide new ideas for the treatment of ovarian cancer in the future.
