To clarify the occurrence and distribution of broad bean wilt virus 2(BBWV2) on Rehmannia glutinosa, this study collected 87 R. glutinosa samples with typical symptoms of viral disease such as chlorosis and crumple from Wenxian county and Wuzhi county in Jiaozuo city, Henan province and Qiaocheng district in Bozhou city, Anhui province. The BBWV2 CP target band was amplified from 37 R. glutinosa samples by RT-PCR technology. The total detection rate reached 42.5%, among which 43.0% was detected in samples from Henan province. The detection rate in samples from Anhui province was 37.5%. 37 BBWV2 CP sequences were obtained by cloning and sequencing of BBWV2 positive samples(data has been submitted to GenBank, accession numbers: PP407959-PP407995), and the sequence analysis of these CP sequences with 91 other BBWV2 isolates in GenBank showed a high genetic diversity with a consistency rate of 70.8%-100%. Meanwhile, phylogenetic analysis showed that BBWV2 could be divided into three groups according to CP sequences, among which the BBWV2 in R. glutinosa isolates obtained in this study were all located in group 3. This study identified the differences in the occurrence, distribution, and genetic diversity of BBWV2 in R. glutinosa from Henan province and Anhui province and provided a theoretical basis for the prevention and control of BBWV2.

Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a complex disease that is often accompanied by mental health disorders. However, the potential mechanisms underlying the heterogeneous clinical presentation of CP/CPPS remain uncertain. This study analyzed widely targeted metabolomic data of expressed prostatic secretions (EPS) and plasma to reveal the underlying pathological mechanisms of CP/CPPS. A total of 24 CP/CPPS patients from The Second Nanning People's Hospital (Nanning, China), and 35 asymptomatic control individuals from First Affiliated Hospital of Guangxi Medical University (Nanning, China) were enrolled. The indicators related to CP/CPPS and psychiatric symptoms were recorded. Differential analysis, coexpression network analysis, and correlation analysis were performed to identify metabolites that were specifically altered in patients and associated with various phenotypes of CP/CPPS. The crucial links between EPS and plasma were further investigated. The metabolomic data of EPS from CP/CPPS patients were significantly different from those from control individuals. Pathway analysis revealed dysregulation of amino acid metabolism, lipid metabolism, and the citrate cycle in EPS. The tryptophan metabolic pathway was found to be the most significantly altered pathway associated with distinct CP/CPPS phenotypes. Moreover, the dysregulation of tryptophan and tyrosine metabolism and elevation of oxidative stress-related metabolites in plasma were found to effectively elucidate the development of depression in CP/CPPS. Overall, metabolomic alterations in the EPS and plasma of patients were primarily associated with oxidative damage, energy metabolism abnormalities, neurological impairment, and immune dysregulation. These alterations may be associated with chronic pain, voiding symptoms, reduced fertility, and depression in CP/CPPS. This study provides a local-global perspective for understanding the pathological mechanisms of CP/CPPS and offers potential diagnostic and therapeutic targets.

Peri-implantitis is a pathologic condition associated with dental plaque that occurs in the implant tissue and is characterized by inflammation of the mucous membrane surrounding the implant, followed by the progressive loss of supporting bone. In this study, a case of guided bone regeneration therapy based on plaque control of peri-implant inflammation was reported. Four years after surgery for the left second premolar implant, the patient presented with "left lower posterior tooth swelling and discomfort for more than 2 years". The X-ray periapical film showed a decrease in distal bone mineral density of implant, and the clinical diagnosis was peri-implantitis of the left second premolar. Implants underwent guided bone regeneration and regular periodontal maintenance treatment. Re-examination at 3.5 months, 11 months, 18 months, and 7 years showed that the alveolar bone height and bone mineral density were stable, and the periodontal depth became shallow. However, the gingival recession was mild. In the present case, follow-up at 7 years demonstrated that the clinical periodontal indexes could be remarkably improved after complete periodontal treatment for peri-implantitis, and the alveolar bone could be well restored and regenerated.

ObjectiveTo investigate the safety and feasibility of intra-biliary drainage tube placement after laparoscopic common bile duct exploration in elderly patients with choledocholithiasis, and to provide more options for surgical procedures in the clinical management of elderly patients with choledocholithiasis. MethodsA retrospective analysis was performed for the clinical data of 52 elderly patients with choledocholithiasis who were admitted to Department of Hepatobiliary Surgery, Affiliated Dalian Friendship Hospital of Dalian Medical University, from November 2021 to October 2024. According to the biliary drainage method after surgery, the patients were divided into internal drainage group with 24 patients and T-tube drainage group with 28 patients, and there were 19 patients in each group after propensity score matching. The two groups were compared in terms of perioperative parameters and postoperative complications. The Wilcoxon rank-sum test was used for comparison of continuous data between two groups, and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. ResultsCompared with the T-tube drainage group, the internal drainage group had a significantly shorter length of postoperative hospital stay and a significantly lower volume of postoperative bile loss (Z=-2.845 and -5.633, both P<0.05), while there were no significant differences between the two groups in time of operation, intraoperative blood loss, and drainage tube indwelling time (all P>0.05). There were no significant differences between the two groups in postoperative bile leak, stone recurrence, biliary stricture, and drainage tube-related complications, and the internal drainage group had a significantly lower total complication rate than the T-tube drainage group [1 (5.3%) vs 7 (36.8%), P<0.05]. ConclusionFor elderly patients with choledocholithiasis, intra-biliary drainage tube placement after laparoscopic common bile duct exploration can shorten the length of postoperative hospital stay, reduce bile loss, and lower the incidence rate of postoperative complications, thereby helping to accelerate postoperative recovery.
5.Diagnosis and treatment status quo of major aortopulmonary collateral arteries in congenital heart disease with decreased pulmonary blood flow
International Journal of Pediatrics 2024;51(2):95-98
The congenital heart disease with decreased pulmonary blood flow is one type of congenital heart disease characterized by reduced pulmonary blood flow. Common clinical types include tetralogy of Fallot,pulmonary atresia,double outlet right ventricle,and other complex malformations associated with pulmonary artery stenosis. Due to the lack of pulmonary blood supply from the right ventricle,children with this condition often have major aortopulmonary collateral arteries(MAPCAs)or the ductus arteriosus participating in pulmonary circulation for blood supply. Research has revealed that MAPCAs are important factors which cause the increase of mechanical ventilation time,intensive care unit stay time,complication rate and mortality after radical surgical treatment of congenital heart disease with decreased pulmonary blood flow. Therefore,the treatment of MAPCAs in perioperative period is crucial. This article summarizes the research progress of MAPCAs distribution and influence,diagnosis and evaluation,and treatment methods,to provide the reference for clinicians to standardize MAPCAs treatment.

【Objective】 To explore the effects of finasteride on the gene expression in patients with benign prostatic hyperplasia (BPH) through transcriptome analysis. 【Methods】 Postoperative prostate tissues from patients who underwent prostatectomy at Peking University Third Hospital during Oct.2020 and Oct.2021 were collected.The patients were divided into medication group and non-medication group based on whether they had taken finasteride for a long time before surgery, with 8 patients in either groups.Transcriptome sequencing analysis was performed and the results were validated with qPCR and immunohistochemistry analysis. 【Results】 Compared with the non-medication group, 857 up-regulated and 806 down-regulated genes were screened in the medication group.Pathway enrichment analysis showed that finasteride induced down-regulation of vascular endothelial growth factor D (VEGFD) expression in the focal adhesion pathway.Inter group network analysis suggested that the calcium signaling pathway was key in the entire process.GSEA enrichment analysis further revealed the up regulation of CD38 gene expression in the calcium signaling pathway.The qPCR and immunohistochemistry analysis supported the transcriptome results mentioned above, and found that androgen receptor (AR) expression was also increased. 【Conclusion】 Finasteride reduces prostate microvascular formation by downregulating the expression of VEGFD in the focal adhesion pathway, thereby reducing the risk of bleeding during prostate hyperplasia surgery. Long-term use of finasteride leads to the up regulation of CD38 expression in the calcium signaling pathway, which may lead to the development of finasteride resistance.

Objective:To evaluate the long-term efficacy of percutaneous microwave ablation (MWA) therapy for hepatocellular carcinoma.Methods:2054 cases with Barcelona Clinic Liver Cancer (BCLC) stage 0~B at the Fifth Medical Center of the Chinese People's Liberation Army General Hospital from January 2006 to September 2020 were retrospectively collected. All patients were followed up for at least 2 years. The primary endpoint of overall survival and secondary endpoints (tumor-related survival, disease-free survival, and postoperative complications) of patients treated with ultrasound-guided percutaneous MWA were analyzed. Kaplan-Meier method was used for stratified survival rate analysis. Fine-and-Gray competing risk model was used to analyze overall survival.Results:A total of 5 503 HCC nodules [mean tumor diameter (2.6±1.6) cm] underwent 3 908 MWAs between January 2006 and September 2020, with a median follow-up time of 45.6 (24.0 -79.2) months.The technical effectiveness rate of 5 375 tumor nodules was 97.5%. The overall survival rates at 5, 10, and 15-years were 61.6%, 38.8%, and 27.0%, respectively. The tumor-specific survival rates were 67.1%, 47.2%, and 37.7%, respectively. The free tumor survival rates were 25.8%, 15.7%, and 9.9%, respectively. The incidence rate of severe complications was 2.8% (108/3 908). Further analysis showed that the technical effectiveness and survival rate over the passing three time periods from January 2006-2010, 2011-2015, and 2016-September 2020 were significantly increased, with P ?0.001, especially for liver cancer 3.1~5.0 cm ( P ?0.001). Conclusion:Microwave ablation therapy is a safe and effective method for BCLC stage 0-B, with significantly enhanced technical efficacy and survival rate over time.
