Objective To observe the effect of Xingnao Kaiqiao Acupuncture on cognitive impairment post stroke. Methods Fifty-four patients from July, 2013 to December, 2015 with cognitive impairment post stroke were randomly divided into experimental group (accepted Xingnao Kaiqiao Acupuncture and repetitive transcranial magnetic stimulation) and control group (repetitive transcranial magnetic stimula-tion only). They were assessed with Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) before and 4 weeks after treatment. Results The scores of MMSE and MoCA improved after treatment in both groups (t>3.52, P<0.01), and improved more in the experimental group than in the control group (t>2.29, P<0.05). Conclusion Xingnao Kaiqiao Acupuncture may further im-proved the recovery of cognitive impairment post stroke based on repetitive transcranial magnetic stimulation.

Objective To explore the medical coping strategies and impact factors of patients with coronary heart disease in Wuhan.Methods Both medical coping strategies and impact factors of 90 patients with coronary heart disease in Wuhan were analyzed by using Spearman coefficient and multiple linear regression analysis,and compared with the norm of 701 cases.Results Compared with the norm,patients with coronary heart disease in Wuhan preferred less facing coping strategies and more avoidance coping strategies:(17.89±2.67) points vs.(19.48±3.81) points,(16.95±2.54) points vs.(14.44±2.97) points,and there were significant differences (t=2.146,P=0.035;t=1.994,P=0.048).The yielding coping strategies was indicated insignificant differences (t=1.758,P=0.173).The facing coping strategies were correlated with age (r=-0.212,P=0.036),education levels (r=0.190,P=0.041),family monthly income (r=-0.106,P=0.049) and disease course (r=0.327,P=0.017).The avoidance coping strategies were correlated with marital status (r=-0.304,P=0.013).The yielding coping strategies were correlated with length of disease(r=0.294,P=0.023)and therapy methods (r=0.308,P=0.017).Conclusions Based on patients' characteristics and impact factors,nursing staff should guide and encourage patients to use positive medical coping styles.

Objective To set up the optimized conditions,the amplification of eord blood CDCD+34 cells in vitro were analyzed by comparing the conditions such as different feeder-layers, stimulating-factors or purity/contents of those cells. Methods The cord blood CDCD+34 cells proliferation was analyzed by the methods of MTT, cell counting, and flow eytometer. The amplification and clone-forming ability of cord blood CDCD+34 cells were detected under optimized condition. Resulits The growth rates of cord blood CD+34 cell under optimized conditions(10 times) were significantly higher than that of the control(2.8 times) (P ＜0.01), and the cloneforming ability of cord blood CDCD+34 cells under optimized conditions(CFU-C 36.67±6.11) were also better than that of the control(CFU-C 16.33±1.53) (P ＜0.01). Conclusion The cord blood CD+34 cells proliferation can be promoted in the co-cultured system, and the character of the stem cells were kept well in that system.

Objective: To analyze the clinical characteristics of young patients with acute myocardial infarction (AMI), discuss the key points of health education in young patients with AMI, enhance the understanding of patients, and improve the prognosis of AMI in the young patients. Methods: hTe patients were chosen in XiangyaHospital from September 2012 to September 2013. We consulted the medical records, analyzed the clinical characteristics and results of coronary angiogram in young patients (age≤45), and compared with old patients (age≥60). Results: There were 69 young patients with AMI, about 14.2% of all the patients with AMI. Of the 69 young patients, 59 were male (85.5%) and 10 were female (14.5%). Compared with the old patients, the percentages of smoking, drinking, hyperlipidemia and overweight were much higher;the percentages of hypertension and diabetes were much lower in young patients. The coronary angiogram showed that the constituent ratios of insigniifcant disease and single-vessel disease inthe young patients were higher than those in the old patients; the constituent ratios of double-vessel disease and triple-vessel disease in the young patients were lower than those in the old patients. Conclusion: The clinical characteristics of young patients withAMI are different from the old patients.Health education should be conducted in the youth, and new diet and lifestyle should be advocated.

Objective To study the prevalence of toenail onychomycosis in the patients with diabetes mel-litus. Methods The incidence and predisposing factors of onychomycosis were studied in the in- and out-patients with diabetes mellitus(n = 456). The data were also compared with non-diabetic patients (control group, n = 350). Results The prevalence rates of toenail onychomycosis were 20.8% and 9.4% in the diabetics and control group, respectively, with statistical difference (P

OBJECTIVETo evaluate the effects of Attractin (Atrn) silence on the anti-oxidative and anti-apoptotic abilities of TM4 Sertoli cells and its influence on the expressions of superoxide dismutase (SOD) and caspase6 in the cells.

METHODSWe observed the apoptotic indexes of TM4 Sertoli cells with normal expression (control), partial deletion, and complete deletion of the Atrn gene (psiRNA-TM4, psiAtrn-TM4, and mu-SC). We determined the mRNA and protein expressions of SOD and caspase6 by Q-PCR and Western blot, measured the SOD activity and malondialdehyde (MDA) contentby spectrophotometry, and detected the apoptotic index of the cells by TUNEL.

RESULTSCompared with psiRNA-TM4, after inhibition of the Atrn expression, the Sertoli cells in the psiAtrn-TM4 and mu-SCgroups showed significantly decreased expressions ofSOD mRNA (70.76% and 92.58%) and protein (65.11% and 71.0%) (both P < 0.05). The levels of caspase 6 mRNA and protein were increased 5.28 and 3.40 times in the psiAtrn-TM4 and 2.97 and 2.50 times in the mu-SCgroup as compared with the normal control (both P < 0.05). Atrn deletion markedly increased the apoptotic indexes of the cells in the psiAtrn-TM4 and mu-SC groups by 16.22% and 22.03% (P < 0.05) and reduced the activity of SOD by 23.00% and 39.37% (P < 0.05); it also elevated the level of MDA by 155.22% (P < 0.05).

CONCLUSIONThe Atrn gene exerts influence on the function of Sertoli cells in multiple ways, in which antioxidative stress and apoptosis regulation may play an important role.

BACKGROUND:Vascular endothelial growth factor is found the strongest to promote angiogenesis, which show strong expression in synovial cells in rheumatoid arthritis.
OBJECTIVE:To evaluate the relation between the expression of vascular endothelial growth factor and microvessel density in rheumatoid arthritis.
METHODS:Col agen II and complete Freund’s adjuvant were used to induce experimental arthritis in Sprague-Dawley rats. Synovium expression of vascular endothelium growth factor and microvessel density were assayed at different time points using immunohistochemistry method, and changes in new vessels, vascular endothelial growth factor expression and arthritis index were observed along the time course. The correlations between vascular endothelial growth factor expression and number of new blood vessels as wel as between arthritis index and vascular endothelial growth factor expression were studied with linear correlation analysis and rank correlation analysis, respectively.
RESULTS AND CONCLUSION:With the time lasting, new blood vessels in the synovium proliferated, the synovium was thickened, and the arthritis index rose gradual y as wel as vascular endothelial growth factor expression and number of new microvessels were on the rise. Vascular endothelial growth factor expression was positively correlated with arthritis index (r=0.535, P<0.05) and significantly positively correlated with number of new microvessels (r=0.860, P<0.01). Vascular endothelial growth factor is involved in the course of synovium pannus response, and vascular endothelial growth factor and microvessel density may play an important role in rheumatoid arthritis pathogenesis.

Objective To investigate effect of low molecular weight heparin (LMWH)on oxidative stress and renal function in elderly patients undergoing gastrectomy of stomach neoplasms. Methods 90 elderly patients undergoing radical surgery were randomly divided into LMWH group (Ⅰ group,n=45)and control group (Ⅱ group,n=45). Patients inⅠ group received a subcutaneous injection of LMWH(100 u/kg,1/d)from the time before anesthesia induction to postoperative 5 days,and patients in Ⅱ group were given equal volume of saline. Venous blood samples were collected to determine level of malondialdehyde(MDA),aldose reductase(AR)activity level,superoxide dismutase(SOD)activity level,catalase (CAT)activity level,creatinine(Cr)and blood urea nitrogen(BUN)before anesthesia induction(T0 ),at the end of the surgery(T1 ),on postoperative 1 day(T2),3 days(T3)and 5 days(T4)respectively;urine specimen were also collected to measured albumin(Alb)and N-acetyl-beta-D-amino glycosidase enzymes(NAG)at the same time points. Results There were obvious statistical differences in MDA,AR,SOD and CAT at different time points by intra-group comparison (P<0.05 ). MDA and AR rose first and then fell in two groups,and both reached the peak at T2 ,whereas SOD and CAT had the opposite trends. There were obvious statistical differences in MDA,AR,SOD and CAT at T1 ~T3 (P<0.05 ). MDA and AR inⅠgroup at T1 ,T2 and T3 was lower than those in groupⅡ(P<0.05 ),whereas SOD and CAT inⅠgroup at T1 ,T2 and T3 were significantly higher than those in group Ⅱ(P<0.05). Cr and BUN of both groups were found no significant statistical difference within the group and between groups(P>0.05).Alb/Cr of both groups at T1 and T2 were significantly higher than those at T0 (P<0.05 ),while Alb/Cr in Ⅰ group at T1 was obviously lower than Ⅱgroup(P<0.05 ).NAG/Cr in both groups at T1 ,T2 and T3 were significantly higher than those at T0 (P<0.05 ),while NAG/Cr inⅡ group at T4 was still higher than that at T0 (P<0.05 ),and NAG/Cr inⅠgroup at T1 ~T4 was obviously lower thanⅡgroup (P<0.05 ). MDA and AR in both groups at T1 ,T2 were positively correlated with Alb/Cr and NAG/Cr respectively(P<0.05 ),whereas SOD and CAT in both groups at T1 ,T2 were negatively correlated with Alb/Cr and NAG/Cr respectively(P<0.05 ). Conclusion Oxidative stress reaction resulted from radical surgery of elderly patients is associated with perioperative renal damage. LMWH could reduce oxidative stress in elderly patients,and alleviate the kidney damage,as well as protect the renal function.
