ObjectiveTo investigate the clinical efficacy and mechanisms of Qigui Didang decoction in the treatment of kidney collateral stasis syndrome in patients with stage Ⅲ-Ⅳ diabetic kidney disease （DKD） in a real-world setting. MethodsPatients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome admitted to Beijing Aerospace General Hospital from January 2022 to December 2024 were selected for clinical study. According to treatment methods， patients were divided into the Qigui Didang decoction group （Qigui Didang decoction + conventional treatment） and the control group （conventional treatment alone）. A 1∶1 propensity score matching （PSM） method was used to reduce bias caused by confounding factors. Clinical efficacy， traditional Chinese medicine （TCM） symptom scores， renal function indicators， mRNA expression related to pathway mechanisms， glycolipid metabolism indices， and adverse reactions were compared between the two groups. ResultsA total of 120 patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome were included， including 62 cases in the Qigui Didang Decoction group and 58 cases in the control group. Before matching， there were statistically significant differences between the two groups in DKD stage， baseline urinary albumin-to-creatinine ratio （UACR）， 24-hour urine total protein （24 h-UTP）， and estimated glomerular filtration rate （eGFR） （P<0.05）. After matching， 47 cases were included in each group， and there was no statistically significant difference in baseline data between the two groups. After matching， the total clinical effective rate of the Qigui Didang decoction group was significantly higher than that of the control group （χ²=4.681， P<0.05）. Compared with data before treatment， the scores of primary and secondary TCM symptoms in the Qigui Didang decoction group were significantly decreased （P<0.05）. Compared with data before treatment， serum creatinine （SCr）， 24 h-UTP， and UACR levels were significantly decreased， while eGFR was significantly increased in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， the mRNA expression of silent information regulator 1 （Sirt1） was significantly upregulated， while the mRNA expression of nuclear factor-kappa B （NF-κB） and tumor suppressor protein p53 （p53） was significantly downregulated in the Qigui Didang decoction group （P<0.05）. Compared with data before treatment， fasting plasma glucose （FPG）， 2-hour postprandial plasma glucose （2 hPG）， glycated hemoglobin A1c （HbA1c）， total cholesterol （TC）， triglycerides （TG）， and low-density lipoprotein cholesterol （LDL-C） levels were decreased， while high-density lipoprotein cholesterol （HDL-C） levels were increased （P<0.05）. There was no statistically significant difference in adverse reactions between the two groups. ConclusionQigui Didang decoction combined with conventional treatment can significantly improve renal function， glycolipid metabolism， and TCM syndromes in patients with stage Ⅲ-Ⅳ DKD with kidney collateral stasis syndrome， with good safety. The mechanism may be related to the regulation of the Sirt1/NF-κB/p53 signaling pathway.

Objective:To investigate the safety and efficacy of laparoscopic fundoplication in the treatment of gastroesophageal reflux related cough (GERC).Methods:Clinical data of 138 GERC patients undergoing laparoscopic fundoplication at our center from Jan 2013 to Dec 2017 were analyzed and patients were followed up until Dec 2022.Results:A total of 138 patients underwent surgery successfully.The median follow-up time was 51 (7-130) months.There were no mortality,nor major complications. In 138 GERC patients, GERC was cured in 85 patients,the cure rate of fundoplication was 61.6%, and altogether 112 patients reported effective, the effective rate was 81.2%. Multivariate regression analysis showed that normal esophageal peristalsis was independent predictors of good efficacy of fundoplication[ OR=3.810(1.373,10.573), P=0.01]. Conclusions:Laparoscopic fundoplication has long term efficacy for refractory GERC. Esophageal motility is an important dynamic characteristic that affects the postoperative efficacy of GERC.

Objective To explore the effects of aberrant O-glycosylation modifications induced by the knockout of Cosmc or T-synthase genes on the expression profiles of miRNAs in exosomes derived from colorectal cancer cells and to reveal the molecular mechanisms of O-glycosylation in the development of colorectal cancer and identify potential biomarkers for early diagnosis and treatment.Methods This research specifically targets the Cosmc or T-synthase genes in the human colorectal cancer cell line HCT116 to create stable cell lines exhibiting abnormal O-glycosylation with CRISPR/Cas-9 gene editing technology.Exosomes originating from these colorectal cancer cells were isolated and authenticated.A microarray chip equipped with primer sequences for 16 miRNAs closely associated with colorectal cancer was employed to assess the differential expression of miRNAs within these exosomes with fluorescent quantitative polymerase chain reaction(PCR).And then,a cohort of miRNAs that exhibited significant and consistent changes in expression levels across the exosomes from both cell lines was selected.These miRNAs were further validated independently with traditional fluorescent quantitative PCR.Subsequently,data from The Cancer Genome Atlas Program(TCGA)database containing patient information on colorectal cancer was harnessed.Employing R programming language,Gene Set Enrichment Analysis(GSEA)was conducted on the upregulated miRNA to investigate the downstream pathways significantly impacted and the malignant biological behaviors they may influence.Results The absence of either Cosmc or T-synthase genes results in the dysregulation of O-glycosylation in colorectal cancer cells,leading to the exposure of Tn antigens.This,in turn,affects the expression levels of specific miRNAs in exosomes derived from these cells.Specifically,the expression of hsa-miR-125b-1-3p was downregulated,while that of hsa-miR-218-5p was upregulated.Notably,hsa-miR-218-5p were found to be closely associated with the epithelial-mesenchymal transition(EMT)process in tumor cells,which is a key mechanism in cancer progression.Conclusion It elucidates that the aberrant O-glycosylation mediated by the knockout of Cosmc or T-synthase genes significantly influences the expression of certain miRNAs in exosomes from colorectal cancer cells,potentially affect the EMT process in colorectal cancer and thereby promoting distant metastasis.Given the inherent stability and detectability advantages of colorectal cancer-derived exosomes,the altered expression levels of miRNAs within these exosomes may serve as indicators of the stated of abnormal O-glycosylation in colorectal cancer.These findings suggest that exosomal miRNAs have potential as biomarkers for monitoring disease progression and therapeutic efficacy.Consequently,this could pave the way for more personalized diagnostic and treatment strategies tailored to individual colorectal cancer patients,enhancing the precision and effectiveness of clinical management.

Gallstones are the primary benign disease diagnosed and treated in biliary surgery.With the development of medical technology and the increasing awareness of health among the population,the detection rate of gallstones has been increasing annually,with the majority being asymptomatic or mild cases.Currently,the clinical treatment of gallstones mainly includes observation,conservative,or surgical treatment(laparoscopic cholecystectomy).However,there remains some controversy regarding the clinical management of these patients.For asymptomatic or mild gallstones,the main point of contention in both academic and clinical settings is how to determine the indications for cholecystectomy.This article reviews relevant literature from both domestic and international sources,addressing the controversies surrounding the clinical management of gallstones and the determination of indications for cholecystectomy,and elaborates on these issues from multiple perspectives.
