The key pathogenesis of coronary heart disease （CHD） is spleen deficiency and phlegm stasis， and dysfunctional high-density lipoprotein （dys-HDL） may be the biological basis for the occurrence of CHD due to spleen deficiency and phlegm stasis. Considering the biological properties and effects of high-density lipoprotein （HDL）， it is believed that the structure and components of HDL are abnormal in the state of spleen deficiency which led to dys-HDL； and dys-HDL contributes to the formation of atherosclerotic plaques through two major pathways， namely， mediating the dysfunction of endothelial cells and mediating the foaminess of macrophages and smooth muscle cells， thus triggering the development of CHD. It is also believed that dys-HDL is a microcosmic manifestation and a pathological product of spleen deficiency， and spleen deficiency makes foundation for the production of dys-HDL； dys-HDL is also an important biological basis for the phlegm-stasis interactions in CHD. The method of fortifying spleen， resolving phlegm， and dispelling stasis， is proposed as an important principle in the treatment of CHD by traditional Chinese medicine， which can achieve the therapeutic purpose by affecting the changes in the structure and components of dys-HDL， thus revealing the scientific connotation of this method， and providing ideas for the diagnosis and treatment of CHD by traditional Chinese medicine.

Background::Lymph node staging of prostate cancer (PCa) is important for planning and monitoring of treatment. 18F-prostate specific membrane antigen positron emission tomography/computerized tomography ( 18F-PSMA PET/CT) has several advantages over 68Ga-PSMA PET/CT, but its diagnostic value requires further investigation. This meta-analysis focused on establishing the diagnostic utility of 18F-PSMA PET/CT for lymph node staging in medium/high-risk PCa. Methods::We searched the EMBASE, PubMed, Cochrane library, and Web of Science databases from inception to October 1, 2022. Prostate cancer, 18F, lymph node, PSMA, and PET/CT were used as search terms and the language was limited to English. We additionally performed a manual search using the reference lists of key articles. Patients and study characteristics were extracted and the QUADAS-2 tool was employed to evaluate the quality of included studies. Sensitivity, specificity, the positive and negative likelihood ratio (PLR and NLR), diagnostic odds ratio (DOR), area under the curve (AUC), and 95% confidence interval (CI) were used to evaluate the diagnostic value of 18F-PSMA PET/CT. Stata 17 software was employed for calculation and statistical analyses. Results::A total of eight diagnostic tests including 734 individual samples and 6346 lymph nodes were included in this meta-analysis. At the patient level, the results of each consolidated summary were as follows: sensitivity of 0.57 (95% CI 0.39-0.73), specificity of 0.95 (95% CI 0.92-0.97), PLR of 11.2 (95% CI 6.6-19.0), NLR of 0.46 (95% CI 0.31-0.68), DOR of 25 (95% CI 11-54), and AUC of 0.94 (95% CI 0.92-0.96). At the lesion level, the results of each consolidated summary were as follows: sensitivity of 0.40 (95% CI 0.21-0.62), specificity of 0.99 (95% CI 0.95-1.00), PLR of 40.0 (95% CI 9.1-176.3), NLR of 0.61 (95% CI 0.42-0.87), DOR of 66 (95% CI 14-311), and AUC of 0.86 (95% CI 0.83-0.89).Conclusions::18F-PSMA PET/CT showed moderate sensitivity but high specificity in lymph node staging of medium/high-risk PCa. The diagnostic efficacy was almost equivalent to that reported for 68Ga-PSMA PET/CT. Registration::International Prospective Register of Systematic Reviews (PROSPERO), No. CRD42023391101.

The second plenary session of the 20th Central Commission for Discipline Inspection proposed the"develop-ment of a five-year plan for information technology construction to establish a digital disciplinary inspection and supervision system that covers the entire process and all elements."This provides guidance and momentum for disciplinary inspection agencies at all levels to implement the strategic deployment of the Party's 20th National Congress regarding comprehensive and strict governance of the Party.In this context,utilizing information technology to enhance the efficiency of supervision,discipline enforcement,and accountability while ensuring the high-quality development of public hospitals has become a key task for their disciplinary inspec-tion departments.The Disciplinary Inspection Commission of a public hospital has explored the establishment of a disciplinary in-spection management platform to achieve modular management of inspection tasks.By utilizing functions such as task allocation,statistical analysis,data migration,and early warning reminders,the platform aims to improve the efficiency of disciplinary in-spection work.This approach helps address the challenges of heavy workloads and limited inspection resources in hospitals,enab-ling real-time supervision,early warning correction,and time-bound oversight,thereby providing strong support for the construc-tion of integrity in the hospital.

Objective To address the challenges of poor performance and lack of interpretability in existing models,the SHAP algorithm is used to develop an interpretable machine learning model that offers a novel approach to wound age estimation,Methods Based on the previous discovery of the expression of 35 wound age healing-related genes in contused skeletal muscle,the woun age estimaton model was constructed using four algorithms,namly,Multilayer Perceptron(MLP),Random Forest(RF),LightGBM(LGBM),and Support Vector Machine(SVM).The SHAP(Shapley Additive Explanation)algorithm was used to rank the importance of genetic features,eliminate redundant attributes,and optimize the model for accurate wound age estimation.the genetic features of the optimal model were analyzed using SHAP's local interpretation capabilities.Results The best results were obtained using model of MLP(area under the curve(AUC)=0.99)The wound ages were classified into four categories:4～12 h,16～24 h,28～36 h,and 40～48 h,using only 15 gene features.According to SHAP analysis,Fam210a was identified as the most relevant gene.Local analysis revealed that high expression of Fam210a contributed to an increase in the predicted probability of 4 h～12 h,while high expression of Rae1 contributed to an increase in the predicted probability of 16 h～24 h.Additionally,low expression of Tbx18 contributed to an increase in the predicted probability of 28 h～36 h,whereas high expression of Tbx18 contributed to an increase in the predicted probability of 40 h～48 h.Conclusions The combined MLP and SHAP model can be used to predict wound age.Using the SHAP interpreter can better understand the degree of contribution of feature genes to the model prediction,and lay the foundation for further in-depth study of wound age estimation.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with unclear etiology and limited treatment options. The median survival time for IPF patients is approximately 2-3 years and there is no effective intervention to treat IPF other than lung transplantation. As important components of lung tissue, endothelial cells (ECs) are associated with pulmonary diseases. However, the role of endothelial dysfunction in pulmonary fibrosis (PF) is incompletely understood. Sphingosine-1-phosphate receptor 1 (S1PR1) is a G protein-coupled receptor highly expressed in lung ECs. Its expression is markedly reduced in patients with IPF. Herein, we generated an endothelial-conditional S1pr1 knockout mouse model which exhibited inflammation and fibrosis with or without bleomycin (BLM) challenge. Selective activation of S1PR1 with an S1PR1 agonist, IMMH002, exerted a potent therapeutic effect in mice with bleomycin-induced fibrosis by protecting the integrity of the endothelial barrier. These results suggest that S1PR1 might be a promising drug target for IPF therapy.

Mulberry (Morus alba L.) leaf is a well-established traditional Chinese botanical and culinary resource. It has found widespread application in the management of diabetes. The bioactive constituents of mulberry leaf, specifically mulberry leaf flavonoids (MLFs), exhibit pronounced potential in the amelioration of type 2 diabetes (T2D). This potential is attributed to their ability to safeguard pancreatic β cells, enhance insulin resistance, and inhibit α-glucosidase activity. Our antecedent research findings underscore the substantial therapeutic efficacy of MLFs in treating T2D. However, the precise mechanistic underpinnings of MLF's anti-T2D effects remain the subject of inquiry. Activation of brown/beige adipocytes is a novel and promising strategy for T2D treatment. In the present study, our primary objective was to elucidate the impact of MLFs on adipose tissue browning in db/db mice and 3T3-L1 cells and elucidate its underlying mechanism. The results manifested that MLFs reduced body weight and food intake, alleviated hepatic steatosis, improved insulin sensitivity, and increased lipolysis and thermogenesis in db/db mice. Moreover, MLFs activated brown adipose tissue (BAT) and induced the browning of inguinal white adipose tissue (IWAT) and 3T3-L1 adipocytes by increasing the expressions of brown adipocyte marker genes and proteins such as uncoupling protein 1 (UCP1) and beige adipocyte marker genes such as transmembrane protein 26 (Tmem26), thereby promoting mitochondrial biogenesis. Mechanistically, MLFs facilitated the activation of BAT and the induction of WAT browning to ameliorate T2D primarily through the activation of AMP-activated protein kinase (AMPK)/sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor-gamma coactivator 1α (PGC-1α) signaling pathway. These findings highlight the unique capacity of MLF to counteract T2D by enhancing BAT activation and inducing browning of IWAT, thereby ameliorating glucose and lipid metabolism disorders. As such, MLFs emerge as a prospective and innovative browning agent for the treatment of T2D.

BACKGROUND: Re-biopsy of metastasis in advanced breast cancer (ABC) has become an international convention to assist the diagnosis and evaluation of tumor heterogeneity. This study aimed to detect diagnostic diversity and inconsistencies among estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) expression levels between primary and metastatic lesions. METHODS: We conducted a retrospective analysis of 1670 cases of ABC patients who had undergone at least one lesion re-biopsy from January 2010 to December 2018. The pathological diagnosis of biopsies, distribution of biopsy sites, and severe puncture complications at each site were collected. In addition, the inconsistency rates and related factors of ER, PR, and HER2 expression between primary and metastatic lesions were analyzed fully considering patients' demographic profiles and disease characteristics. RESULTS: In total, 1670 cases of breast cancer (BC) patients diagnosed by pathology underwent one to four biopsies of recurrences or metastases in different sites or at different stages during the rescue treatment, producing 2019 histopathological specimens which were analyzed in the study. Pathological diagnosis showed that eight patients had benign pathological diagnoses, 11 patients had second primary malignant tumors but without recurrences of breast cancer, and 17 patients had pathologically confirmed breast cancer recurrences combined with second primary cancer. In 1173 patients who presented ER, PR, and HER2 expressions in primary and metastatic lesions, the inconsistency rates of ER, PR, and HER2 were 17.5% (205/1173), 31.3% (367/1173), and 13.9% (163/1173), respectively. The multivariate analysis showed that the age at the onset of breast cancer or adjuvant endocrine therapy was an independent factor affecting changes in PR expression level. Except one liver puncture with local hemorrhage and two lung punctures with hemopneumothorax, no other severe puncture complications occurred in 1950 non-surgical rebiopsies. CONCLUSIONS The pathological diagnosis of metastasis re-biopsy of ABC was diverse, and the ER, PR, and HER2 expression levels were inconsistent between primary and metastatic lesions. Therefore, more attention should be paid to perform biopsies of relapsed and metastatic breast cancers routinely in clinical practice.

Viral-encoded microRNAs (miRNAs) have vital roles in the regulation of virus replications and host immune responses. The results of previous studies have indicated that miRNA clusters are involved in the replication and virulence of the pseudorabies virus (PRV), which may potentially lead to immune escape or facilitation of PRV replication. This study's previous research revealed that prv-miR-LLT11a was differentially expressed during PRV infection. The present study's results have demonstrated that prv-miR-LLT11a could significantly inhibit PRV replication. It was further determined that SLA-1 was the target gene of prv-miR-LLT11a, and simultaneously, that overexpression of prv-miR-LLT11a could downregulate the mRNA and protein levels of SLA-1 in a dose-independent manner. Furthermore, the present study also observed that prv-miR-LLT11a can downregulate TAP1 expression. Our findings provide a better understanding of the molecular mechanism involved in the effects of prv-miR-LLT11a on SLA-1 and TAP1 as well as its involvement in immune system evasion of PRV.
