With the rapid increase of the number of cardiovascular disease patients in China, and the popular trend of cardiovascular disease risk factors is becoming more and more obvious, the control of risk factors for cardiovascular disease has become an important public health problem as well as a great challenge to social and economic development. Recent studies show that resistance training plays a positive impact on the control of risk factors for cardiovascular disease. This article reviewed the related literature in recent years for the resistance training control risk factors of the cardiovascular disease, and stated the precautions and challenges during the process of the implementation of resistance training in order to provide new clues to the research and practice for control the risk factors of cardiovascular disease .

Objective:To explore the effect of quality management circulation (plan-do-check-act, PDCA) mode combined with clinical pathway nursing on leakage rate and nursing satisfaction in patients with ascites due to cirrhosis.Methods:A total of 418 patients with cirrhotic ascites in hospital infectious department were selected and divided into control group and 209 patients in study group according to random digital table method. The leakage rate, quality of life score and total nursing satisfaction were compared between the two groups.Results:The local leakage rates were 17.22% (36/209), 14.83% (31/209), 12.92% (27/209), 8.61% (18/209), respectively, at 24 hours, 48 hours, 72 hours and 1 week after abdominal tube placement. The control group was 22.01% (46/209), 20.10% (42/209), 23.92% (50/209), 25.84% (54/209). The difference between 72 hours and 1 week was statistically significant ( χ2 values were 8.421, 1.746, P<0.01). Quality of life scores were (3.15±1.15), (1.25±1.10), (1.15±1.08), (2.40±1.45), (2.35±1.50) in the study group and (3.75±1.05), (3.25±1.05), (3.60±1.25), (4.35±1.25), (3.15±1.25) in the control group, and the difference was statistically significant ( t values were 5.570-21.441, P<0.05). The total satisfaction of the study group was 96.65% (202/209), which was significantly higher than that of the control group 85.65% (179/209), and the difference was statistically significant ( χ2 value was 15.686, P<0.01). Conclusion:PDCA mode combined with clinical pathway nursing can reduce the leakage rate of abdominal administration, improve the quality of life score and nursing satisfaction, and improve the quality of nursing, which is a safe and effective nursing mode.

Objective:To investigate the functional imaging parameters that effectively distinguish isocitrate dehydrogenase (IDH) gene mutation status in clinical practice with long echo time (TE) point-resolved spectroscopy (PRESS) MRS.Methods:Totally 25 patients with suspected diagnosis of low grade gliomas(LGGs; Grade II) were recruited prospectively and divided into IDH mutation group and IDH wild group according to pathological results in the study. All patients were scanned with long TE PRESS MRS. In addition, IDH mutational status was determined by post-operation Sanger sequencing. The t test or Mann-Whitney U test was used to analyze the differences of 2-hydroxyglutarate (2HG), Glutamate (Glu), Glutamine (Gln) and 2HG/Glu+Gln between the IDH mutation group and the IDH wild group, then ROC curve was plotted with statistically significant indexes to obtain the efficacy of predicting IDH mutation status. Results:Of the 25 patients, 19 had IDH mutant gliomas and 6 had IDH wild-type gliomas. 2HG, Glu, Gln and 2HG/Glu+Gln in IDH mutated group were 1.42 (1.09, 1.93)mmol/L, (1.74±1.31)mmol/L, (1.68±0.66)mmol/L, 0.55 (0.28, 0.77), respectively; while the corresponding values were 0.00 (0.00, 1.30)mmol/L, (3.28±1.02)mmol/L, (2.55±1.47)mmol/L, 0.00 (0.00, 0.26) in IDH gene wild type group, respectively. The differences of 2HG, Glu, and 2HG/Glu+Gln between the two groups were statistically significant ( P values were 0.030, 0.016, 0.004, respectively). The area under the ROC curve of 2HG/Glu+Gln was the largest (0.877), and the sensitivity was the highest (84.2%). Conclusion:The integration of 2HG with Glu and Gln can effectively realize the noninvasive assessment of IDH mutation status.

Objective:To develop a novel, flexible, dual-arm, master-slave digestive endoscopic minimally invasive surgical robot system named dual-arm robotic endoscopic assistant for minimally invasive surgery (DREAMS) and to evaluate its feasibility for endoscopic submucosal dissection (ESD) by using ex vivo porcine stomachs.Methods:A novel endoscopic robot (DREAMS) system was developed which was composed of a flexible two-channel endoscope, two flexible robotic manipulators, a master controller, a robotic arm, and a control system. A total of 10 artificial round-like lesions with diameters ranging from 15 to 25 mm were created (5 in gastric antrum and 5 in gastric body) by using fresh peeled stomach of healthy pigs as the model. Submucosal dissection was performed with the assistance of the DREAMS system by two operators. The main outcome was submucosal dissection speed, and the secondary outcomes included muscular injury rate, perforation rate, and grasping efficiency of the robot.Results:All 10 lesions were successfully dissected en bloc by using the DREAMS system. The diameter of the artificial lesions was 22.34±2.39 mm, dissection time was 15.00±8.90 min, submucosal dissection speed was 141.79±79.12 mm 2/min, and the number of tractions required by each ESD was 4.2 times. Muscular injury occurred in 4/10 cases of ESD. No perforation occurred. Conclusion:The initial animal experiment shows the DREAMS system is safe and effective.
