ObjectiveTo observe ovarian microvascular damage in rats with cold coagulation and blood stasis syndrome and to explore the mechanism by which Liangfang Wenjing decoction improves this condition in rats. MethodsFifty SPF female SD rats were randomly divided into a blank group， a model group， low-dose （8.1 g·kg^-1） and high-dose groups （16.2 g·kg^-1） of Liangfang Wenjing decoction， and a 4-phenylbutyric acid （0.1 g·kg^-1） group， with 10 rats in each group. The ice-water bath method was employed to establish the rat model of cold coagulation and blood stasis syndrome. Concurrent with modeling， Liangfang Wenjing decoction was administered continuously for 21 days， once daily. The rats' syndrome manifestations and estrous cycles were recorded. The enzyme-linked immunosorbent assay （ELISA） was used to detect serum reproductive hormone levels and levels of endothelin-1 （ET-1）， nitric oxide （NO）， thrombomodulin （TM）， and von Willebrand factor （vWF） in ovarian tissue. Prothrombin time （PT）， activated partial thromboplastin time （APTT）， thrombin time （TT）， and fibrinogen （FIB） were measured. The ovarian microcirculatory blood perfusion was detected by laser speckle contrast imaging. Hematoxylin-eosin （HE） staining was performed to observe the ovarian histopathology， flow cytometry to detect ovarian apoptosis rate， and transmission electron microscopy to observe the ultrastructure of ovarian microvascular endothelial cells. Western blot was employed to detect the protein expression of endothelial nitric oxide synthase （eNOS）， phosphorylated eNOS （p-eNOS）， Caspase-3， B-cell lymphoma-2 （Bcl-2）， Bcl-2-associated X protein （Bax）， glucose-regulated protein 78 （GRP78）， C/EBP homologous protein （CHOP）， inositol-requiring enzyme1α （IRE1α）， p-IRE1α， apoptosis signal-regulating kinase 1 （ASK1）， p-ASK1， c-Jun N-terminal kinase （JNK）， and p-JNK. Immunofluorescence was used to detect ovarian Bax and Bcl-2 expression in microvascular endothelial cells. ResultsCompared with the blank group， the model group showed signs of cold coagulation and blood stasis syndrome， prolonged estrus cycles， and reproductive hormone disorders. Histopathological results revealed a decrease in follicle counts at all stages and disorganized granulosa cell arrangement. Ovarian microcirculatory perfusion was significantly decreased （P<0.01）. PT， APTT， and TT were reduced （P<0.05， P<0.01）， while FIB levels were increased （P<0.05）. In ovarian tissue， NO content was decreased， while ET-1， vWF， and TM levels were increased significantly （P<0.01）. The apoptosis rate of ovarian cells was markedly increased （P<0.01）. Furthermore， p-eNOS/eNOS and Bcl-2 were decreased （P<0.05）， whereas Bax， cleaved-Caspase-3/Caspase-3， GRP78， CHOP， p-IRE1α/IRE1α， p-ASK1/ASK1， and p-JNK/JNK expression showed significant increases （P<0.05， P<0.01）. Compared with the model group， Liangfang Wenjing decoction intervention alleviated the symptoms of cold coagulation and blood stasis， gradually restored the estrus cycle， and improved ovarian histopathology and endothelial cell ultrastructure. Microcirculatory blood perfusion was significantly elevated （P<0.05）. NO content in ovarian tissue was elevated， while ET-1， vWF， and TM levels were significantly decreased （P<0.05， P<0.01）. The p-eNOS/eNOS ratio and Bcl-2 expression were significantly elevated （P<0.05）， while the expression of Bax， cleaved-Caspase-3/Caspase-3， GRP78， CHOP， p-IRE1α/IRE1α， p-ASK1/ASK1， and p-JNK/JNK was significantly decreased （P<0.05， P<0.01）. ConclusionLiangfang Wenjing decoction may regulate the IRE1α/ASK1/JNK signaling pathway to inhibit endoplasmic reticulum stress， attenuate apoptosis， and improve microvascular endothelial injury in ovaries of rats with cold coagulation and blood stasis syndrome.

Laparoscopic subtotal cholecystectomy (LSC) has been a safe and viable alternative to conversion to laparotomy in cases of severe cholecystitis. The objective of this study is to determine the utility of intraoperative choledochoscopy in LSC for the exploration of the gallbladder, cyst duct, and subsequent stone clearance of the cystic duct in cases of severe cholecystitis. A total of 72 patients diagnosed with severe cholecystitis received choledochoscopy-assisted laparoscopic subtotal cholecystectomy (CALSC). A choledochoscopy was performed to explore the gallbladder cavity and/or cystic duct, and to extract stones using a range of techniques. The clinical records, including the operative records and outcomes, were subjected to analysis. No LSC was converted to open surgery, and no bile duct or vascular injuries were sustained. All stones within the cystic duct were removed by a combination of techniques, including high-frequency needle knife electrotomy, basket, and electrohydraulic lithotripsy. A follow-up examination revealed the absence of residual bile duct stones, with the exception of one common bile duct stone, which was extracted via endoscopic retrograde cholangiopancreatography. In certain special cases, CALSC may prove to be an efficacious treatment for the management of severe cholecystitis. This technique allows for optimal comprehension of the situation within the gallbladder cavity and cystic duct, facilitating the removal of stones from the cystic duct and reducing the residue of the non-functional gallbladder remnant.

Evading host immunity killing is a critical step for virus survival. Inhibiting viral immune escape is crucial for the treatment of viral diseases. Serine/threonine kinase 39 (STK39) was reported to play an essential role in ion homeostasis. However, its potential role and mechanism in viral infection remain unknown. In this study, we found that viral infection promoted STK39 expression. Consequently, overexpressed STK39 inhibited the phosphorylation of interferon regulatory factor 3 (IRF3) and the production of type I interferon, which led to viral replication and immune escape. Genetic ablation or pharmacological inhibition of STK39 significantly protected mice from viral infection. Mechanistically, mass spectrometry and immunoprecipitation assays identified that STK39 interacted with PPP2R1A (a scaffold subunit of protein phosphatase 2A (PP2A)) in a kinase activity-dependent manner. This interaction inhibited DDB1 and CUL4 associated factor 1 (DCAF1)-mediated PPP2R1A degradation, maintained the stabilization and phosphatase activity of PP2A, which, in turn, suppressed the phosphorylation of IRF3, decreased the production of type I interferon, and then strengthened viral replication. Thus, our study provides a novel theoretical basis for viral immune escape, and STK39 may be a potential therapeutic target for viral infectious diseases.

Digital technologies have become an integral part of complete denture restoration. With advancement in computer-aided design and computer-aided manufacturing (CAD/CAM), tools such as intraoral scanning, facial scanning, 3D printing, and numerical control machining are reshaping the workflow of complete denture restoration. Unlike conventional methods that rely heavily on clinical experience and manual techniques, digital technologies offer greater precision, predictability, and efficacy. They also streamline the process by reducing the number of patient visits and improving overall comfort. Despite these improvements, the clinical application of digital complete denture restoration still faces challenges that require further standardization. The major issues include appropriate case selection, establishing consistent digital workflows, and evaluating long-term outcomes. To address these challenges and provide clinical guidance for practitioners, this expert consensus outlines the principles, advantages, and limitations of digital complete denture technology. The aim of this review was to offer practical recommendations on indications, clinical procedures and precautions, evaluation metrics, and outcome assessment to support digital restoration of complete denture in clinical practice.

Personalized drug response prediction from molecular data is an important challenge in precision medicine for treating cancer. Computational methods have been widely explored and have become increasingly accurate in recent years. However, the clinical application of prediction methods is still in its infancy due to large discrepancies between preclinial models and patients. We present a novel disentangled synthesis transfer network (DiSyn) for drug response prediction specifically designed for transfer learning from preclinical models to clinical patients. DiSyn uses a domain separation network (DSN) to disentangle drug response related features, employs data synthesis technology to increase the sample size and iteratively trains for better feature disentanglement. DiSyn is pretrained on large-scale unlabeled cancer samples and validated by three datasets, The Cancer Genome Atlas (TCGA), Investigation of Serial Studies to Predict Your Therapeutic Response With Imaging And moLecular Analysis 2 (I-SPY2) and Novartis Institutes for Biomedical Research Patient-Derived Xenograft Encyclopedia (NIBR PDXE), achieving competitive performance with the state-of-the-art methods on cancer patients and mice. Furthermore, the application of DiSyn to thousands of breast cancer patients show the heterogeneity in drug responses and demonstrate its potential value in biomarker discovery and drug combination prediction.

OBJECTIVE: We aimed to investigate the patterns of fasting blood glucose (FBG) trajectories and analyze the relationship between various occupational hazard factors and FBG trajectories in male steelworkers. METHODS: The study cohort included 3,728 workers who met the selection criteria for the Tanggang Occupational Cohort (TGOC) between 2017 and 2022. A group-based trajectory model was used to identify the FBG trajectories. Environmental risk scores (ERS) were constructed using regression coefficients from the occupational hazard model as weights. Univariate and multivariate logistic regression analyses were performed to explore the effects of occupational hazard factors using the ERS on FBG trajectories. RESULTS: FBG trajectories were categorized into three groups. An association was observed between high temperature, noise exposure, and FBG trajectory ( P < 0.05). Using the first quartile group of ERS1 as a reference, the fourth quartile group of ERS1 had an increased risk of medium and high FBG by 1.90 and 2.21 times, respectively (odds ratio [ OR] = 1.90, 95% confidence interval [ CI]: 1.17-3.10; OR = 2.21, 95% CI: 1.09-4.45). CONCLUSION An association was observed between occupational hazards based on ERS and FBG trajectories. The risk of FBG trajectory levels increase with an increase in ERS.

[Summary]Diabetic peripheral neuropathy(DPN)is one of the most common complications of diabetes.The blood nerve barrier(BNB)is a barrier structure located in peripheral nerve tissue,protecting nerve tissue from toxic substances in the blood and maintaining material exchange and information transmission between nerves and blood.Studies have shown that changes in BNB may be the initial event leading to the occurrence of DPN.After BNB is destroyed,blood-borne pathogens can directly damage peripheral nerves and cause DPN.This article will review the physiological and pathological characteristics of BNB,the relationship between BNB and DPN,and the research progress in targeting BNB for the treatment of DPN.

Objective To summarize the changing prevalence of carbapenem resistance in Enterobacterales based on the data of CHINET Antimicrobial Resistance Surveillance Program from 2015 to 2021 for improving antimicrobial treatment in clinical practice.Methods Antimicrobial susceptibility testing was performed using a commercial automated susceptibility testing system according to the unified CHINET protocol.The results were interpreted according to the breakpoints of the Clinical & Laboratory Standards Institute(CLSI)M100 31st ed in 2021.Results Over the seven-year period(2015-2021),the overall prevalence of carbapenem-resistant Enterobacterales(CRE)was 9.43％(62 342/661 235).The prevalence of CRE strains in Klebsiella pneumoniae,Citrobacter freundii,and Enterobacter cloacae was 22.38％,9.73％,and 8.47％,respectively.The prevalence of CRE strains in Escherichia coli was 1.99％.A few CRE strains were also identified in Salmonella and Shigella.The CRE strains were mainly isolated from respiratory specimens(44.23±2.80)％,followed by blood(20.88±3.40)％and urine(18.40±3.45)％.Intensive care units(ICUs)were the major source of the CRE strains(27.43±5.20)％.CRE strains were resistant to all the β-lactam antibiotics tested and most non-β-lactam antimicrobial agents.The CRE strains were relatively susceptible to tigecycline and polymyxins with low resistance rates.Conclusions The prevalence of CRE strains was increasing from 2015 to 2021.CRE strains were highly resistant to most of the antibacterial drugs used in clinical practice.Clinicians should prescribe antimicrobial agents rationally.Hospitals should strengthen antibiotic stewardship in key clinical settings such as ICUs,and take effective infection control measures to curb CRE outbreak and epidemic in hospitals.
