AIM: To obtain eukaryotic expression vector of Chinese prostate-specific membrane antigen. METHODS: Chinese prostate-specific membrane antigen (PSMA) cDNA was amplified by RT-PCR from prostate cancer tissues, then cloned into eukaryotic expression vector pcDNA3 0 and sequenced. RESULTS: Seven bases in Chinese PSMA cDNA sequence were found different from those reported by Israeli, which lead to two different amino acids. CONCLUSION: We have obtained the PSMA cDNA, and the recombinant eukaryotic expression vector was successfully constructed. The study lays foundation for DCs vaccine modified by PSMA gene for the treatment of prostate neoplasms.

Objective:To explore the material basis and mechanism of Linggui Zhugan Decoction in treating hypertension and obesity by means of network pharmacology and molecular docking technique.Methods:The TCMSP was retrieved and the main active components and action targets of Linggui Zhugan Decoction were screened. The GeneCards, OMIM, TTD, DisGeNET and DrugBank databases were used to screen disease-related targets of hypertension and obesity. The Cytoscape 3.9.0 was used to draw Chinese materia medica-composition-intersection target-disease network diagram. The STRING 11.5 database was used to draw PPI network. The cytoNCA plug-in was used to screen core active components and targets. The bioenrichment analysis of GO and KEGG was carried out in the R4.1.2, and the Chinese materia medica-intersection target-path diagram was drawn, and the core active components and core targets were docked in PyMOL and AutoDockTools 1.5.7.Results:A total of 102 potentially active components and 62 intersection targets were obtained, and 8 active components and 7 core targets were screened. Enrichment analysis showed that the key targets were mainly enriched through the signaling pathways of fluid shear stress and atherosclerosis, lipid and atherosclerosis, and AGE-RAGE, which were involved in biological processes such as the response to nutritional levels and the regulation of small molecule metabolism. Molecular docking showed that there were 37 groups with addinity < -7 kcal/mol.Conclusion:The main active components of Linggui Zhugan Decoction are quercetin, kaempferol and naringenin, which may play a role in fluid shear stress and atherosclerosis pathway, lipid and atherosclerosis pathway and AGE-RAGE signal pathway through AKT1, EGFR, IL1B and other targets.

Objective:To analyze the research hotspots and trends of exercise treatment of hypertension in China with bibliometrics software of CiteSpace and VOS viewer.Methods:The databases of CNKI, VIP, WanFang Data and the core collection of Web of Science were searched with the key words of exercise therapy, exercise intervention, exercise prescription, sports, movement, high blood pressure, hypertension, etc. Relevant periodical literature in Chinese and English were retrieved from the establishment of the databases to December 31, 2021. The CiteSpace and VOS viewer were used to perform visual analysis of the literature in the field of exercise therapy for hypertension in China.Results:A total of 1 507 literatures were included, including 1 430 in Chinese and 77 in English. In recent years, the number of studies on exercise treatment of hypertension in China showed a fluctuating upward trend. The research institutions were mainly universities and hospitals, high-yield institutions mainly included Beijing Sport University (20 articles), the First Affiliated Hospital of Nanjing Medical University (12 articles), the PLA General Hospital (13 articles) and Shanghai Sport University (11 articles). There was less cooperation between institutions and less cross-border cooperation. The proportion of sports and medical compound researchers in high-yield authors was relatively low (22.2%, 2/9). Keyword clustering could be summarized as three aspects: disease research, research objects and intervention methods. In terms of disease research, “pregnancy outcome”, “blood pressure”, “blood lipid” and “coronary heart disease” had strong burst (burst intensity 3.75, 3.70, 3.52, 3.12); in terms of research objects, “elderly patients” had the strongest burst (burst intensity 3.10); in terms of intervention methods, “exercise prescription”, “aerobic exercise” and “health education” had strong emergence (emergence intensity 6.08, 5.47, 4.01).Conclusions:Research achievements in the field of exercise therapy for hypertension in China are relatively rich in recent years. At present, the main research hotspots are disease research, research objects and intervention methods, and the integration degree of sports and medicine needs to be improved.

Objective:To further improve the understanding of paroxysmal nocturnal hemoglobinuria (PNH), we retrospectively analyzed and summarized the clinical characteristics, treatment status, and survival status of patients with PNH in Zhejiang Province.Methods:This study included 289 patients with PNH who visited 20 hospitals in Zhejiang Province. Their clinical characteristics, comorbidity, laboratory test results, and medications were analyzed and summarized.Results:Among the 289 patients with PNH, 148 males and 141 females, with a median onset age of 45 (16-87) years and a peak onset age of 20-49 years (57.8% ). The median lactic dehydrogenase (LDH) level was 1 142 (604-1 925) U/L. Classified by type, 70.9% (166/234) were classical, 24.4% (57/234) were PNH/bone marrow failure (BMF), and 4.7% (11/234) were subclinical. The main clinical manifestations included fatigue or weakness (80.8%, 235/289), dizziness (73.4%, 212/289), darkened urine color (66.2%, 179/272), and jaundice (46.2%, 126/270). Common comorbidities were hemoglobinuria (58.7% ), renal dysfunction (17.6% ), and thrombosis (15.0% ). Moreover, 82.3% of the patients received glucocorticoid therapy, 70.9% required blood transfusion, 30.7% used immunosuppressive agents, 13.8% received anticoagulant therapy, and 6.3% received allogeneic hematopoietic stem cell transplantation. The 10-year overall survival (OS) rate was 84.4% (95% CI 78.0% -91.3% ) . Conclusion:Patients with PNH are more common in young and middle-aged people, with a similar incidence rate between men and women. Common clinical manifestations include fatigue, hemoglobinuria, jaundice, renal dysfunction, and recurrent thrombosis. The 10-year OS of this group is similar to reports from other centers in China.

ObjectiveTo build an evaluation index system for traditional Chinese medicine （TCM） medicated diet， promoting the scientific and standardized development of medicated diet in TCM. MethodsThe framework of the evaluation index system was constructed through literature review and Delphi expert consultation method. The analytic hierarchy process was used to construct a hierarchical structure model. Pairwise comparisons between the indicators were conducted using the Saaty 1-9 scale method， and the weight of each indicator was calculated using Yaahp 10.3. ResultsThe response rates for the two rounds of expert consultation were 93.33% and 100%， respectively. The Kendall's W coefficients for the first-level and second-level indicators in the second round were 0.270 and 0.281， respectively （both P＜0.001）. Finally， an evaluation index system for TCM medicated diet therapy was constructed， consisting of 6 primary indicators and 27 secondary indicators. The weightings of the primary indicators were as follows： sensory appearance （0.1843）， health value （0.3569）， ingredient compatibility （0.1271）， packaging （0.0370）， production and preparation （0.1005）， and reliability （0.1940）. ConclusionA comprehensive and universally applicable evaluation index system for TCM medicated diet has been developed， taking into conside-rations of color， taste， appearance， efficacy， preparation， quality and others. This system can provide valuable reference for the evaluation of the value of medicated diet as well as its development.

Obesity is a chronic low-grade inflammation and a risk factor for diseases such as diabetes， hypertension， dyslipidemia， and malignant tumors， demonstrating an increasingly grim development situation. The nuclear factor-kappa B （NF-κB） signaling pathway is a key signaling pathway involved in the immune response and inflammatory response. In obese individuals， the expression of NF-κB is overactivated， which leads to abnormal inflammatory responses in the body. Therefore， it is expected to alleviate inflammation and treat obesity by regulating the NF-κB signaling pathway， which has been proven effective by a large number of studies. The available studies on the NF-κB signaling pathway mostly focus on tumors， and there is no systematic review of the mechanism of this pathway in mediating obesity and the traditional Chinese medicine （TCM） treatment. We reviewed the research progress in the pathological and physiological processes of obesity mediated by NF-κB signaling pathway and TCM treatment， aiming to give insights into the clinical treatment of obesity with TCM and provide reference targets and research directions for exploring the biological foundations and the development of new TCM preparations.
