Objective To explore the possible effects of the microRNA(miR)-143/145 polymorphisms on cardiovascular risk factors and the severity of coronary heart disease(CHD) in Chinese Han people. Methods Polymerase chain reaction-restriction fragment length polymorphism analysis was employed to identify the genotypes of the rs353292 and rs4705343 polymorphisms for 380 patients with CHD and 163 CHD-free controls. The physiological and biochemical parameters between the genotypes were compared in the CHD patients and in controls,and the incidence of myocardial infarction(MI) was also compared between the genotypes in the CHD patients. Results The subjects with the rs353292 TT genotype had higher serum levels of triglycerides(F=3.00,P=0.05) and glucose(F=9.91,P<0.001) than the C carriers,and the subjects with the rs4705343 TT genotype had significantly higher prevalence of hypertension(Χ=6.35,P=0.04) than the C carriers in the control group. The patients with the rs353292 TT genotype had significantly higher serum levels of hypersensitive C-reactive protein(hs-CRP)(F=8.43,P<0.001) than the C carriers in the CHD group,and the frequency of MI was significantly higher in the patients with the rs353292 TT genotype than that in the C carrier patients(Χ=5.29,P=0.02). Conclusion The T allele of the rs353292 polymorphism is associated with serum hs-CRP levels in CHD patients,and it may affect the occurrence and development of MI by up-regulation of CRP gene through miR-143/145. The rs4705343 polymorphism is not related to the risk and severity of CHD.

OBJECTIVE: To analyze the clinical and pathological characteristics of primary gastrointestinal non-Hodgkin's lymphoma (PGI-NHL) patients, and to explore the factors affecting the patients' survival and prognosis. METHODS: The clinical data of 219 patients with PGI-NHL diagnosed in our hospital from March 2009 to April 2016 was collected and retrospectively analyzed. Survival analysis was performed by using the Kaplan-Meier method. Log-rank test was used for comparison among the groups, and Cox regression was used for multivariate analysis. RESULTS: Among the 219 patients with PGI-NHL, 126 patients were males and 93 patients were females. 182 patients were IPI 0 to 2 and 37 patients were IPI 3 to 5. There were 205 cases (93.6%) of B cell phenotype and 14 cases (6.4%) of T cell phenotype. 140 patients (63.9%) were patients with primary gastric NHL, including 85 DLBCL and 19 MALT. 79 cases (36.1%) were patients with primary intestinal NHL, including 46 DLBCL, 4 MALT, 7 FL, 3 MCL and 4 Burkitt lymphoma. 23 cases were HP positive and received anti-HP therapy. 57 cases and 32 cases received surgery and chemotherapy respectively. 84 cases received combination treatment of surgery and chemotherapy and 11 cases received combination treatment of radiotherapy and chemotherapy. Overall survival (OS) of indolent B-cell non-Hodgkin's lymphoma was longer than that of invasive B-cell non-Hodgkin's lymphoma, which shows better prognose. Kaplan-Meier analysis showed that there was no difference between progression-free survival (PFS) and OS in the patients with different origin sites, age and sex. There was no significant difference in PFS between B-cell and T-cell-derived patients, whereas OS of B-cell-derived PGI-NHL patients was longer than that of T-cell-derived PGI-NHL patients. The OS and PFS of patients with IPI 0-2 were longer than those of patients with IPI 3-5. According to Lugano and Ann Arbor staging systems, there was no difference in prognosis of patients between phase I/II and III/IV. The prognosis of patients treated with surgery alone was worse than that of patients treated with combination therapy, and the prognosis of patients with surgery combined with chemotherapy was not significantly different from that of patients with chemotherapy alone. CONCLUSION B-cell phenotype, indolent and low IPI score lymphoma indicate better prognosis, while that of different origin site, sex and age shows no different in prognosis. Surgery is used only for emergency case or pathological materials, and these patients should be treated with chemotherapy-based combined treatment.

OBJECTIVE: To study the trend of surgical type, surgical procedure and etiological distribution of upper urinary tract repair in recent 10 years. METHODS: The preoperative and perioperative variables and follow-up data of upper urinary tract reconstruction surgery in RECUTTER (Reconstruction of Urinary Tract: Technology, Epidemiology and Result) database from 2010 to 2021 were searched, collected and analyzed. The surgical type, surgical procedure, duration of hospitalization, time of operation, incidence of short-term complications, and proportion of the patients undergoing reoperations were compared between the two groups of 2010-2017 period and 2018-2021 period. RESULTS: A total of 1 072 patients were included in the RECUTTER database. Congenital factors and iatrogenic injuries were the main causes of upper urinary tract repair. Among them, 129 (12.0%) patients had open operation, 403 (37.6%) patients had laparoscopic surgery, 322 (30.0%) patients had robot-assisted laparoscopic surgery and 218 (20.3%) patients had endourological procedure. In the last decade, the total number of surgeries showed a noticeable increasing annual trend and the proportion of robot-assisted laparoscopic surgery in 2018-2021 was significantly higher than that in 2010-2017 (P < 0.001). The 1 072 patients included 124 (11.6%) cases of ileal ureter replacements, 440 (41.1%) cases of pyeloplasty, 229 (21.4%) cases of balloon dilation, 109 (10.2%) cases of ureteral reimplantation, 49 (4.6%) cases of boari flap-Psoas hitch surgery, 60 (5.6%) cases of uretero-ureteral anastomosis, 61 (5.7%) cases of lingual mucosal onlay graft ureteroplasty or appendiceal onlay flap ureteroplasty. Pyeloplasty and balloon dilatation had been the main types of surgery, while the proportion of lingual mucosal onlay graft ureteroplasty plus appendiceal onlay flap ureteroplasty had increased significantly in recent years (P < 0.05). In addition, the time of operation was significantly increased (P < 0.05) after 2018, which was considered to be related to the sharp increase in the proportion of robot-assisted laparoscopic surgery. We found that minimally invasive surgery (endourological procedure and robot-assisted laparoscopic surgery) as an independent risk factor (P=0.050, OR=0.472) could reduce the incidence of short-term post-operative complications. CONCLUSION We have justified the value of the RECUTTER database, created by the Institute of Urology, Peking University in data support for clinical research work, and provided valuable experience for the construction of other multi-center databases at home and abroad. In recent 10 years, we have observed that, in upper urinary tract reconstruction surgery, the surgery type tends to be minimally invasive and the surgery procedure tends to be complicated, suggesting the superiority of robot-assisted laparoscopic surgery.
