OBJECTIVES:
To investigate the effect of Ching Shum Pills (CSP) for alleviating non-alcoholic fatty liver disease (NAFLD) and the underlying mechanism.
METHODS:
In a mouse model of NAFLD, the therapeutic effect of CSP was evaluated by measuring serum glucose, lipid profiles (TC, TG, LDL-C, HDL-C), and hepatic function markers. Network pharmacology was employed to identify active compounds in CSP and their targets using TCMSP, HERB, SwissTargetPrediction, GeneCards, OMIM, and DisGeNET. Protein-protein interaction (PPI) networks, Gene Ontology (GO), and KEGG pathway analyses were conducted. Molecular docking (AutoDock Vina) was used to assess the compound-target binding affinities. Quantitative real-time PCR (qRT-PCR) was used to validate the mRNA expressions of the core genes in the liver tissue of the mouse models.
RESULTS:
In the mouse model of NAFLD, treatment with CSP significantly reduced body weight gain and serum TG levels of the mice, and high-dose CSP treatment resulted in obvious reduction of ALT levels and hepatic fat accumulation. Network pharmacology analysis identified quercetin and 2-monolinolenin as the key bioactives in CSP, which target TNF, AKT1, IL6, TP53, and ALB. Docking simulations suggested strong binding between the two core compounds and their target proteins. The results of qRT-PCR showed that high-fat diet induced significant downregulation of Tp53, Cpt1, and Ppara expressions in mice, which was effectively reversed by CSP treatment.
CONCLUSIONS
CSP can improve lipid metabolism disorders in NAFLD mice through a regulatory mechanism involving multiple targets and pathways to reduce liver fat accumulation and protect liver function. The key components in CSP such as quercetin and linolenic acid monoacylglycerol may participate in the regulation of such metabolic processes as fatty acid oxidation by targeting TP53.

Purpose/Significance To solve the problem that regional clinical research data are difficult to integrate efficiently,and to promote"Chinese evidence"and"Chinese protocol"in the global clinical research community.Method/Process Based on the standard-ization theory,the data standardization system is proposed,and the construction and application methods of the regional clinical research data platform are explored with the integration of multi-center clinical research data as the starting point.Result/Conclusion The theo-retical framework of the regional clinical research data platform has been preliminarily established,and the clinical research capabilities of tertiary hospitals in Shanghai have been significantly improved.

Objective To investigate the value of radiomics model based on multiple sequences MR in predicting the efficacy of neoadjuvant chemotherapy(NAC)among different breast cancer subtypes.Methods Two hundred breast cancer patients undergoing NAC treatment were retrospectively selected,and then randomly divided into training group and validation group at a ratio of 7:3,as well as divided into responsive and non-responsive according to the therapeutic response.Radiomics features were selected and filtered from multiple sequences MR.The model was established by using machine learning,and validated in the validation group.The predictive performance of the model was evaluated by using receiver operating characteristic(ROC)curve,and the clinical application value of the model was assessed by clinical decision curve analysis(DCA).Results The area under the curve(AUC)of hormone receptor(HR)-positive with human epidermal growth factor receptor-2(HER-2)-negative breast cancer patients in training and validation groups were 0.881 and 0.682,respectively,while the AUC of HER-2-positive breast cancer patients were 0.831 and 0.636,respectively.The AUC of triple-negative breast cancer patients were 0.969 and 0.708,respectively.The clinical DCA showed significant clinical benefits.Conclusion The MR radiomics model can predict the efficacy of NAC among different breast cancer subtypes.

Objective:To explore the self-care experience of arteriovenous fistula in elderly maintenance hemodialysis patients, and to provide reference for intervention and management.Methods:The descriptive phenomenological research method was used to select elderly patients as subjects who underwent hemodialysis and used arteriovenous fistula as vascular access in the blood purification center of The First Affiliated Hospital of Zhejiang University School of Medicine from November 2022 to May 2023 through objective sampling, and semi-structured in-depth interviews were conducted on them, and the data were analyzed by Colaizzi 7-step analysis method.Results:Finally, 15 interviewees were included. There were 6 males and 9 females, aged (73.53±8.59) years old. A total of 4 themes and 12 sub-themes were summarized: multiple burdens (comorbidities management burden, psychological burden, financial burden), self-care dilemmas (affected by physical decline, inadequate self-coping, inadequate counseling channels), driven by social factors (motivated by social feedback, influenced by peer behavior, promoted by extended medical services) and understanding of life philosophy (actively coping with life changes, replanning life order, appreciating life value).Conclusions:Elderly maintenance hemodialysis patients have complicated burden experience, multi-dimensional problems and needs in the process of self-care for internal arteriovenous fistula, and self-care behavior is greatly affected by social factors. Future intervention should focus on strengthening multidisciplinary collaboration, providing professional and convenient continuous nursing services, improving social support paths and giving accurate psychological intervention, so as to reduce the burden of disease management of patients, meet their self-care needs, enhance the internal motivation of self-care behavior and improve self-care ability.

Background::Although the treatment of peripheral T-cell lymphoma (PTCL) has undergone advancements during the past several years, the response rate and long-term effects with respect to patients with PTCL remain unsatisfactory—particularly for relapsed or refractory (R/R) patients. This phase II trial was designed to explore the efficacy and safety of an all-oral regimen of chidamide plus prednisone, cyclophosphamide, and thalidomide (CPCT) for R/R PTCL patients who could not tolerate the standard chemotherapy for a variety of reasons.Methods::We conducted a multicenter phase II clinical trial in which we combined chidamide (30 mg twice weekly) with prednisone (20 mg daily after breakfast), cyclophosphamide (50 mg daily after lunch), and thalidomide (100 mg daily at bedtime) (the CPCT regimen) for a total of fewer than 12 cycles as an induction-combined treatment period, and then applied chidamide as single-drug maintenance. Forty-five patients were ultimately enrolled from August 2016 to April 2021 with respect to Chinese patients at nine centers. Our primary objective was to assess the overall response rate (ORR) after the treatment with CPCT.Results::Of the 45 enrolled patients, the optimal ORR and complete response (CR)/CR unconfirmed (CRu) were 71.1% (32/45) and 28.9% (13/45), respectively, and after a median follow-up period of 56 months, the median progression-free survival (PFS) and overall survival (OS) were 8.5 months and 17.2 months, respectively. The five-year PFS and OS rates were 21.2% (95% confidence interval [CI], 7.9-34.5%) and 43.8% (95% CI, 28.3-59.3%), respectively. The most common adverse event was neutropenia (20/45, 44.4%), but we observed no treatment-related death.Conclusion::The all-oral CPCT regimen was an effective and safe regimen for R/R PTCL patients who could not tolerate standard chemotherapy for various reasons.Trial Registration::ClinicalTrials.gov, NCT02879526.

An increasing number of studies in recent years have focused on the association between female endometrial microbiota and fertility.Once the endometrial microflora microecology is unbalanced,it will cause a series of endometrial lesions,thereby destroying endometrial receptivity,affecting embryo implantation,resulting in embryo implantation or implantation failure.Among them,the most concerned is the positive significance of lactobacillus-led microbiota on reproductive outcome.Although the relationship between endometrial microbiota and reproductive outcome has not reached a consensus,most studies recognize the positive impact of lactobacillus-led microbiota on reproductive outcome.In this review,the relationship between lactobacillus-dominated microbiota and reproductive outcome is reviewed.
