Objective To investigate the clinical curative effect of“Qing Dynasty Palace manipulation” in combination with plaster immobilization and foot bath with traditional Chinese medicine for acute soft tissue sprain of the ankle.Method A total of 90 patients with acute soft tissue sprain of the ankle from emergency department of WangJing Hospital, CACMS were recruited from July 2013 to April 2014 and randomly divided into two groups with 45 patients in each. The patients in the treatment group were treated with the court manipulation, plaster and Chinese herbs washing, and those in the control group were only treated with cast immobilization. The clinical curative effect was evaluated using Baird-Jackson score system(excellent: 96-100; good: 91-95; fair: 81-90; poor: 0-80).Result At the second, third week after treatment, the excellent/good rates in the treatment group were significantly higher than those in the control group(at week 2: 73.3%vs. 44.4%;χ2=11.468,P<0.01; at week 3: 86.7%vs.60.0%;χ2=6.875,P<0.05). At week 2 and 3, Baird-Jackson scores in the treatment group(87.41±14.12, 93.16±9.51)and in the control group(76.32±11.41, 82.54±9.22)were significantly higher than those before treatment(treatment group: 72.11±12.61; control group: 71.67±13.12, allP<0.05); at week 3, Baird-Jackson score in the treatment group were significantly higher than that in the control group(P<0.05).Conclusion“Qing Dynasty Palace manipulation” in combination with plaster immobilization and foot bath with traditional Chinese medicine can increase Baird-Jackson score and aid recovery of the ankle function in patients with acute soft tissue sprain of the ankle.

AIM: To investigate the expression of matrix metalloproteinases (MMPs), membrane type MMPs (MT-MMPs) and their inhibitors (TIMPs) in human primary cultured prostatic cells and malignant prostate cell lines.METHODS: Reverse transcription-polymerase chain reaction-based measurements of the mRNA levels of MMP-2, MMP-7, MMP-9, MT1-MMP, MT3-MMP, TIMP-1 and TIMP-2 in relation to the house-keeping gene glyceraldehydes phosphate dehydrogenase were performed in cancerous and non-cancerous prostatic tissue samples, in primary cell cultures of epithelial cells, in both fibroblasts and smooth-muscle cells as stromal cells, and in the human malignant prostatic cell lines DU-145, LNCaP and PC-3.RESULTS: MMP-2 was mainly expressed in stromal cells. MMP-7 and MMP-9 showed their highest values in epithelial cells. MT1-MMP, MT3-MMP, TIMP-1 and TIMP-2 were found both in stromal and in epithelial cells, but there were some differences between the expression in fibroblasts and smooth-muscle cells. Different expression was also observed between the cells deriving from the primary cell cultures, the benign cell line BPH-1, and the malignant cell lines LNCaP, DU-145, and PC-3.CONCLUSION: These results concerning different expression of MMPs and TIMPs in cells from prostatic tissue suggest that a better insight into changes observed in prostatic tissue needs studies on cells cultured from the tissue.

Objective To investigate the correlation between food intolerance and Henoch-Sch(o)nlein purpura (HSP) in children and the efficacy of food forbidden or alternative therapy. Methods The levels of IgG against several common food in serum obtained from 40 children with HSP were measured by ELISA. The efficacy of food forbidden or alternative food therapy was assessed after 3 months. Results Total positive rate of serum food-intolerant IgG antibodies in HSP children was 92.5%. Among these 14 intolerant foods, the positive percentage of egg was the highest (33.8%), followed by tomato (14.9%), milk (13.5%) and morrhua (12.2%). Significant differences of the sort and degree of food intolerance existed among different age groups (t=2.257, P=0.045), but not between boys and girls (t=1.053, P=0.315), city and countryside (t= 1.388, P=0.193). There was no linear correlation between total food intolerance and serum IgG level (t=0.793, P=0.445). Food intolerance had no direct relation to immune complex deposition in kidneys of HSP nephritis (r =-0.262, P =0.387). The efficacy of adjusting diet was 95% . Conclusions HSP is closely related to food intolerance. Egg is the most common intolerant food. Food forbidden or alternative therapy shows acceptable efficacy in the treatment of most Henoch-Sch(o)nlein purpura children.

Cardiomyocyte autophagy plays an important role in maintaining normal cardiac structure and function.Recent studies have shown that cardiomyocyte autophagy is decreased in the aging heart.The expression of autophagy-related genes Atg5, Atg7 and Beclin1 decreases in the aging myocardium.Decreased cardiomyocyte autophagy in the aging heart is associated with dysregulation of phosphatidylinositol-3-kinase(PI3K)/serine-threonine kinase(Akt)/mammalian target of rapamycin(mTOR), adenosine monophosphate-activated protein kinase(AMPK)and/or the SIRT1 signaling pathways.In addition, reactive oxygen species and some neural hormonal factors such as endothelin-1 can also mediate the decrease of cardiomyocyte autophagy in cardiac aging.The regulation of cardiomyocyte autophagy may provide new strategies for the prevention and treatment of cardiomyopathy in the elderly.

Objective: To explore the clinical response on cardiac resynchronization therapy (CRT) in patients of chronic heart failure (CHF) with different QRS wave morphology. Methods: A total of 52 CHF patients received CRT in our hospital and the Seventh People's Hospital of Zhengzhou City from 2010-03 to 2013-07 were retrospectively studied. The patients were divided into 3 groups: True-complete left bundle branch block (t-CLBBB) group,n=20, Classic LBBB (CLBBB) group,n=15 and IVCD group,n=17. The general clinical condition, the indexes of echocardiography at 6 months of follow-up study including left ventricular end diastolic diameter (LVEDD), left ventricular ejection fraction (LVEF), NYHA classiifcation and 6-MWT were examined and compared among different groups. Results: In general clinical condition, the ratio of non-ischemic heart disease patients in t-CLBBB group was higher than those in CLBBB group and IVCD group, allP<0.05. By 6 months follow-up study, LVEDD in t-CLBBB group (62.6 ± 8.9) mm was lower than those in CLBBB group (70.0 ± 8.9) mm and IVCD group (72.8 ± 8.0) mm, LVEF was higher in t-CLBBB group (38.5 ± 6.2) % than those in CLBBB group (31.7 ± 6.7) % and IVCD group (30.1 ± 6.7) %. NYHA classiifcation in t-CLBBB group (2.00 ± 0.45) grade was lower than those in CLBBB group (2.73 ± 0.80) grade and IVCD group (3.12 ± 0.78) grade . 6-MWT in t-CLBBB group (302.0 ± 57.9) m was longer than those in CLBBB group (257.3 ± 59.0) m and IVCD group (220.2 ± 57.9) m, allP<0.05. Conclusion: CRT is an effective method for treating CHD patients, different QRS morphology may have different response, the patients with t-CLBBB would make better response.
