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.

Cyclic peptide drugs have gradually become an emerging research direction due to their some favorable properties such as high-efficiency binding affinity, high selectivity, lower toxicity, and stable metabolism. In recent years, the number of cyclic peptide drugs under clinical research has continued to increase. Unlike the previous cyclic peptide drugs, which were mostly derived from natural products and their derivatives, these cyclic peptide drugs are designed by genetically encoded display technologies which are based on rational design and in vitro evolution (such as BT1718, PTG-300, POL6326, etc). Among them, phage display technology has some advantages such as mature research system, low cost, and simpler operation that make it well recognized and praised by the majority of researchers in this field. Here, we reviewed the recent progress of applying phage display technology to explore diverse cyclic peptide libraries, which, we believe, will contribute more valuable candidate cyclic peptide drugs in clinical research.

In the proposed training program,medical ethics education and comprehensive training including clinical thinking and practical skills training should be emphasized.Scientific inquisitiveness of the neurological research and the writing and oral communication in English should also be promoted.This training program will be fully committed to produce highly qualified,ethical and caring neurosurgeons for future needs of the society.

Objective To construct human apolipoprotein O (apolipoprotein O, ApoO) expression vector and obtain recombinant fusion protein thioredoxin (Trx)-ApoO by pET prokaryotic expression system. Methods The ApoO gene fragment from the human liver cDNA library was amplified by PCR. The resulting product was cloned into pET-32a(+) vector and sequenced. The confirmed cDNA was cloned into plasmid E.coli DH10B and then transformed into E.coli BL 21 (DE3) where it was induced to express protein by isopropyl β-D-1-thiogalactopyranoside (IPTG).The fusion protein was purified by Ni-NTA resin. Results The ApoO gene was cloned by PCR and a 519 bp DNA fragment was shown on the agarose electrophoresis. The cloned gene was sequenced and demonstrated to have the same sequence as that of human ApoO gene in GenBank which justified a successful construction of recombinant plasmid. ApoO cDNA gene fragment was induced by IPTG, and a 34 kD recombinant fusion protein Trx-ApoO was tested on sodium dodecyl sulfate polyacrylamide (SDS-PAGE). Conclusion Human ApoO gene is successfully cloned and its recombinant fusion protein Trx-ApoO is expressed.

Objective To study the mechanism of oxidative damage in myocardial tissue after limb ischemia reperfusion (IR), and the protective effects of heme oxygenase-1 on myocardial injury in experimental rats. Method The models of bilateral hind limbs ischemia and reperfusion in rats were established by using tourniquets applied to the roots of both hind limbs until palm blanched and pulseless for 4 hours. A total of 56 SD rats were randomly (random number) divided into 7 groups, namely one normal control group ( n = 8) and 6 ischemia-reperfusion groups as per different lengths of reperfusion time, e. g. 2 hrs, 4 hrs, 8 hrs, 16 h rs and 24 hr ( n = 8 each). The experimental rats were sacrificed after different lengths of reperfusion time. Specimens of myocardium and blood were taken for assays of malonaldehyde (MDA), superoxide dismutase (SOD) and myeloperoxidase (MPO), and pathological changes of myocardium were observed, and the expressions of HO-1 mRNA in myocardium were detected. Data were analyzed with ANOVA. Results (1) Compared with the control group, the levels of serum MDA and myocardial MDA of rats were increased in all IR groups and were higher (P < 0.05), and the levels of MDA reached the peak after reperfusion for 4 hours. The levels of serum SOD and myocardial SOD in rats of all IR groups were decreased and lower than those in rats of the control group ( P < 0.05), and the levels of serum SOD dropped away to the lowest point after reperfusion for 4 hours, and the levels of myocardial SOD fell off to the bottom after reperfusion for 8 hours. The levels of serum MPO and myocardial MPO were significantly increased in rats of all IR groups compared with the control group (P < 0.05). The levels of serum MPO reached peak after reperfusion for 4 hours, and the levels of myocardial MPO were increased to the highest spot after reperfusion for 6 hours. (2) The pathological changes in myocardium showed the most severe damage after reperfusionfor 4-6 hours.(3) After reperfusion for 2 hours, there were no significant differences in the expression of HO-1 mRNA between IR groups and control group (P >0.05), and after reperfusion for 4 hours and over, the expressions of HO-1 mRNA were markedly increased in IR groups and reached peak after reperfusion for 16 hours in comparison with the control group (P < 0.05). Conclusions The activation of neutrophils and free radicals may play a primarily adverse role in myocardial injury after limb IR, and the increase in the expression of HO-1 mRNA lessens the harm effects of IR on myocardium.

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 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

OBJECTIVE To study the imprinting status of H19 gene in normal villi tissue during the first trimester,and its relation to the invasion of trophoblast. METHODS Using PCR-RFLP methods to examine the imprinting status of H19 gene in 93 cases of normal villi tissue during the first trimester. RESULTS Among 93 cases, heterozygous genotypes were found in 42 cases. And 11 cases of biallelic expression were found among these 42 cases of heterozygous genotypes from 5 to 9 weeks, however no biallelic expression existed from 10 to 12 weeks. CONCLUSIONS During the first trimester, H19 is expressed biallelically at the first 10 weeks. The H19 gene may dynamicly change in the trophoblast, and the dynamic change may have close relationship with the invasion of the trophoblast.
