For coronary artery diseases, imaging diagnosis is usually used to guide the treatment. However, it can only reflect the geometric characteristics of the disease but does not determine the hemodynamically significant stenosis. This study was aimed to investigate the relationship between angiographic and functional severity of coronary artery stenosis and to improve the diagnostic value of imaging. 39 patients with 55 stenosis vessels were included in this study. The correlation between FFR and stenosis rate was analyzed with the medical statistical analysis method, and the influence of the position of stenosis and coronary dominant type on the correlation was discussed. By regression analysis, the stenosis rate of left anterior descending artery of right dominant type showed a significant correlation with FFR value (r≈0.79, P < 0.000 1) after grouping with position and the dominant type. Due to the significance of a value of the FFR < 0.80 in determining inducible ischemia, the diagnostic accuracy of myocardial ischemia by the stenosis rate increased from 70.9% to 82.8% after grouping. Sensitivity (from 72.2% to 78.6%) and specificity (from 70.3% to 86.7%) were also significantly improved. This study indicates that the position of stenosis and the coronary dominant type are significant influence factors on the correlation between FFR and stenosis rate. Consideration of these two factors in the diagnosis of myocardial ischemia by imaging will be helpful to improve the effectiveness of diagnosis.
ObjectiveTo systematically review the efficacy of Chinese herbal enema in ileus patients. MethodsThe randomized controlled trials (RCTs) and quasi-RCTs about Chinese herbal enema and gastrointestinal intubation versus western medicines in the treatment of ileus disease was searched in PubMed, Web of Science, EMbase, The Cochrane Library (Issue 4, 2013), CBM, CNKI, VIP and WanFang Data from the date of their establishment to July 2013. Two reviewers independently screened literature according to the inclusion and exclusion criteria, extracted data, and assessed the methodological quality of included studies. Then meta-analysis was performed using RevMan 5.1. ResultsA total of 27 RCTs and 3 quasi-RCTs involving 3 074 patients were included. The results of meta-analysis showed that the Chinese herbal enema and gastrointestinal intubation group was superior to the control group in raising the total clinical effective rate (OR=4.69, 95%CI 3.70 to 5.94, P < 0.000 01), as well as shortening the hospitalization time (SMD=-1.19, 95%CI-1.42 to-0.96, P < 0.000 01), time of anus exhaust (SMD=-1.52, 95%CI-1.76 to-1.28, P < 0.000 01), defecation (SMD=-2.27, 95%CI-3.43 to-1.11, P=0.000 1), time of gastric tube indwelling (SMD=-1.56, 95%CI-1.86 to-1.27, P < 0.000 01), and symptoms complete resolution (SMD=-0.74, 95%CI-1.11 to-0.37, P < 0.000 1), all with significant differences. ConclusionChinese herbal enema and gastrointestinal intubation is more beneficial than western medicine alone for ileus. Due to limited quality of the included studies, the abovementioned conclusion still needs to be verified by conducting more high quality blinding RCTs.
ObjectiveTo investigate effect of application of thymopentin during perioperative period on immune function of patients undergoing laparoscopic assisted radical resection for rectal carcinoma. MethodsForty-two patients undergoing laparoscopic assisted radical resection for rectal carcinoma from January 2015 to April 2015 in this hospital were collected. These patients were divided into study group and control group. The patients were received routine treatment in the control group. In addition to routine treatment same as the control group, the patients were received 2 mg thymopentin every day for a week in the study group. The changes of lymphocyte count, T lymphocyte subsets (CD3+, CD4+, CD8+, and CD4+/CD8+), and immunoglobulin (IgG, IgA, and IgM) were compared on the 1st day before surgery and on the 1st day and 5th day after surgery. ResultsThe lymphocyte count, T lymphocyte subsets, and immunoglobulin on the first day after surgery were significantly lower than those on the 1st day before surgery in these two groups (P < 0.05). The lymphocyte count, T lymphocyte subsets (except for CD4+/CD8+), and immunoglobulin (except for IgA) in the study group were significantly higher than those in the control group on the 5th day after surgery (P < 0.05). The changes of lymphocyte count, T lymphocyte subsets, and immunoglobulin in the study group had no significant differences between on the 5th day after surgery and on the 1st day before surgery (P > 0.05), but which on the 5th day afer surgery were significantly lower than those on the 1st day before surgery (P < 0.05) in the control group. ConclusionApplication of thymopentin during perioperative period could accelerate recovery of immune function after operation in patients undergoing laparoscopic assisted radical resection for rectal carcinoma.
