BACKGROUND@#Traditional Chinese exercises (TCEs) have a positive effect on glycemic control and hemoglobin A1c (HbA1c), but there is no consensus on the benefits of TCEs for patients with prediabetes.@*OBJECTIVE@#The objective of this study was to systematically investigate the effects of TCEs on blood glucose control in patients with prediabetes.@*SEARCH STRATEGY@#Comprehensive retrieval of randomized controlled trials (RCTs) was carried out using PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodicals, Wanfang Data Knowledge Service Platform, China Biology Medicine disc, Google Scholar and Baidu academic databases. The retrieval window ranged from the establishment of the database to December 2018, and references related to the included trials were searched without language restrictions.@*INCLUSION CRITERIA@#The study included RCTs with a clinical diagnosis of prediabetes that was also treated with TCEs.@*DATA EXTRACTION AND ANALYSIS@#Literature screening, data extraction and literature quality assessment were performed independently by two researchers. In the case of disagreement, a third party was invited to negotiate and make a decision. Standardized mean difference (SMD) was used to estimate the therapeutic effect. Meta-analysis was performed using Review Manager 5.3.5 and Stata 15.0. Heterogeneity was assessed using Q test and I, and the source of heterogeneity was determined using Galbraith diagram and sensitivity analysis. A Q test resulting in P  50% indicated significant difference and random effect model analysis was performed. Otherwise, a fixed effect model was applied. Begg's and Egger's tests were used to assess publication bias.@*RESULTS@#Nine RCTs involving 485 participants were included in this study. The results showed that TCEs could reduce fasting blood glucose (FBG), 2 h blood glucose (2hPBG) and HbA1c in patients with prediabetes. The treatment subgroup showed that an intervention of 6 months had better results, while the Gongfa subgroup showed that the TCE Baduanjin yielded better results. (1) FBG: SMD = -0.73, 95% confidence interval (CI) [-0.97, -0.50], P < 0.00001; Baduanjin: SMD = -0.83, 95% CI [-1.13, -0.53], P < 0.00001; 6 month treatment: SMD = -0.73, 95% CI [-1.20, -0.26], P = 0.002. (2) 2hPBG: SMD = -0.75, 95% CI [-0.94, -0.57], P < 0.00001; Baduanjin: SMD = -0.62, 95% CI [-0.91, -0.32], P < 0.00001; 6 month treatment: SMD = -0.91, 95% CI [-1.39, -0.44], P = 0.0002. (3) HbA1c: SMD = -0.56, 95% CI [-0.89, -0.23], P = 0.00008; Baduanjin: SMD = -0.46, 95% CI [-0.83, -0.08], P = 0.02; 6 month treatment: SMD = -0.77, 95% CI [-1.24, -0.29], P = 0.002.@*CONCLUSION@#TCEs had positive effects in improving blood glucose levels in patients with prediabetes. Hence, TCEs may be of potential therapeutic value for patients with prediabetes, as an adjuvant therapy along with other treatments. Although the evidence suggests that the intervention is effective for 6 months, the mechanism of TCEs on glycemic control, the minimum exercise dose and their safety remain to be further studied.

<p><b>OBJECTIVE</b>To study the pathological change of rats' benign hyperplastic prostate (BHP) after radical denervation.</p><p><b>METHODS</b>A total of 65 male spontaneous hypertension rats (SHR) at 30 weeks age were randomly assigned into treatment group, sham surgery control group and normal control group. In surgery group, all the axonal branches of the major pelvic ganglion (MPG) supplying the bilateral prostate were truncated, followed performing of cystostomy; In sham surgery control group, only cystostomy was performed; In normal control group, no procedure was performed. The rats were sacrificed at 3, 7, 11, 15 and >or= 21 d post-operation respectively. The gross morphological changes of prostate in all animals were observed.</p><p><b>RESULTS</b>In treatment group, the prostate in 3 d post-operation showed granular solidification and shrunken volume and the changes occurred gradually over time. The glandular epithelial cells showed gradual degeneration, necrosis and detachment. The glandular epithelium became progressively thinner, the smooth muscles elongated and thinned progressively and the stromal components showed mild to moderate overgrowth. At the later stage, the glandular epithelium, glandular lumen and smooth muscles gradually disappeared and the prostate was largely replaced by connective tissues. Electron microscopic study showed that the glandular cells gradually underwent vacuolar degeneration and the structures of basement membrane became fuzzy. The smooth muscles cells degenerated overtime and the fibroblasts and collagenous fibers in the stroma overgrew slowly. At the late stage, most of the glandular cells became necrotic, the basal membrane and smooth muscle cells disappeared and collagenous fibers were highly hyperplasic. In surgery group in 3 d post-operation, the S-100 staining of nerve fiber was diffuse and disappeared after 11 d while it persisted normally in other groups. The two values in sham surgery control group showed no significant changes post-operatively.</p><p><b>CONCLUSIONS</b>After radical denervation, the rat prostate with benign hyperplasia (gland and smooth muscles) undergoes dramatic atrophic changes and the volume decreases significantly. It suggests that this treatment may represent a novel therapy for BPH.</p>
