Aim To explore the clinical significance of the vWF in the patients with essential hypertension(EH). Methods vWF were measured with enzyme linked immunoabsorbent assay(ELISA) in 103 EH patients and 30 normal controls. The vWF values were compared by age ,gender,and stages of hypertension. Results There were markedly rise in EH patients than that in the normal controls. The vWF was increased with the age and stage of hypertension. The highest vWF was found in male over seventy years. Conclusion vWF may serve as an indicator of injury of endothelium. A positive correlation between endothelium lesion and age was found.

Objective To analysis effect of breviscapine on serum and copeptin, NT-proBNP, HIF-1αand IMA in patients with acute ischemic brain vascular disease.Methods 42 patients who were diagnosed with acute ischemic brain vascular disease were collected and randomly divided into experimental group and control group, each group had 21 cases.All patients were given conventional treatment of Western medicine, on this basis, control group was given vinpocetine injection 20 mg, once daily intravenous drip;experimental group given Dengzhan flower Suting injection 20 mg, once daily intravenous drip; continuous treatment for 2 weeks.Before and after the treatment, the serum levels of copeptin, HIF-1α, NT-proBNP and IMA were detected in two groups.ResuIts Compared with control group, patients in experimental group treatment effect was better, as follows: serum copeptin content decreased significantly ( P<0.05 ) .Serum NT-proBNP levels decreased significantly ( P<0.05 ) .Serum levels of HIF-1αcontent decreased significantly (P<0.05).Serum ACB value increased significantly (P<0.05).ConcIusion Breviscapine can reduce the acute ischemic brain vascular disease patients serum copeptin, NT-proBNP, HIF-1αand IMA content, and has good therapeutic effect in patients with acute ischemic cerebral vascular disease.

Objective To explore the correlation between verbal memory and working memory in patients with alcohol dependence (AD).Methods A total of 40 patients with AD and 40 health controls were included in this study.N-back task was used to evaluate the verbal working memory.20 sets of phrases were used to evaluate long-term verbal memory.Results Correct number of verbal memory in AD group ((5.15±0.92)times) was lower than that of HC group ((7.35±3.07) times) after one-week baseline test,and the difference was statistically significant (t=4.344,P＜ 0.01).Compared with HC group ((1 436.37±192.50) ms,(1.08±0.89) times,(4.00±0.85) times,respectively),AD group((1 535.40± 192.50) ms,(1.90± 1.57)times,(2.60± 1.39)times) showed significantly impaired reply reaction time of 2-back,error number of 1-back and 2-back (t=-2.112,P=0.038;t=-2.899,P=0.005;t=-5.433,P＜0.01).The error number of 2-back task in AD group was negative correlated with verbal memory after one-week baseline test (r=-0.427,P=0.006).Conclusion The verbal memory is impaired in AD patients.Long-term verbal memory damage have a certain correlation with working memory.

Objective To explore the values of electromyography to examine birth injuries.Methods 34 cases of birth injuries were studied,the electromyography and motor nerve conduction of brachial plexcy were recorded.Then,the location and severity of birth injuries were determined.Results Among 34 cases,according to the location of injuries,there were 10 cases of upper trunk injuries,7 cases of upper and middle trunk injuries,5 cases of middle and lower trunk injuries,5 cases of lower trunk injuries,and 7 cases of whole brachialplexus injuries.On the other hand,according to the severity of injuries,there were one case of complete injuries and 33 cases of incomplete injuries which included 2 cases of severe injuries and 31 cases of slight injuries.Conclusion Electromyography is the reliable method to identify the location and severity of brachial plexus injuries,and this examination is necessary to diagnose birth injuries with great clinical values.

AIM: To investigate the dynamic expression of Rho kinase(ROCK I) and transforming growth factor ?1(TGF-?1) in pulmonary arterioles of rat with chronic thromboembolic pulmonary hypertension.METHODS: Sixty-four male Wister rats were randomly divided into eight groups: beginning control group,embolism for 3 d,1 week,2 weeks,4 weeks,8 weeks,12 weeks groups and end control group.The pulmonary thromboembolism(PTE) model was established by injecting thrombin into jugular vein two times in two weeks and each rat underwent peritoneal injection with tranexamic acid one time a day during experiment to prevent thrombolysis.The mean pulmonary artery pressure(mPAP),right ventricular hypertrophy index(RVHI),relative medial thickness of small pulmonary arteries(PAMT) and vessel wall area/total area(WA/TA) were measured.The levels of ROCK I mRNA and TGF-?1 protein in rat pulmonary artery were determined by in situ hybridization,immunohistochemistry and image analysis,respectively.RESULTS: mPAP,PAMT and WA/TA were higher respectively in embolism from 4 weeks group to 12 weeks group than those in beginning control group(mPAP: all P

We have designed and carried out problem based learning (PBL) pedagogy since 2004. According to clinical eases, students learnt the pathophysiology of heart failure knowledge by themselves. Each group recommen-ded one student to make an oral presentation and wrote a review about heart failure. Preparing clinical cases and group discussions are very important. At the same time we should pay attention to the change in role of the teacher in PBL and cooperation with other disciplines.

ObjectiveTo establish a method for measuring exhaled nitric oxide (eNO)concentrations in neonates with and without hypoxemic respiratory failure ( HRF), and to investigate the relationship between eNO and respiratory parameters in neonates with HRF. Methods Twenty-two newborn infants with HRF and 26 control neonates were included within the first 24 hours of postnatal life.Their eNO levels were detected with a rapid-response chemiluminescence analyzer daily during the first week of their postnatal life, and lung mechanics and gas exchange efficiency were monitored at the same time, such as pulse oxygen saturation ( SpO2 ), inspired fraction of oxygen ( FiO2 ) and other parameters.Wilcoxon Mann-Whitney U tests were used to compare eNO, SpO2/FiO2 and eNO/ ( SpO2/FiO2 × 100) in two groups. Pearson's correlation analyses were used to determine the relationships between eNO levels and indices of hypoxemic respiratory failure. ResultsDuring the first two days of postnatal life, eNO values of HRF neonates were higher than those of the control neonates[day 1,(7. 9 ± 3.2 )× 10-9 vs. (5.8 ±1.8)×10-9, P＜0.05;day2, (8.8±3.2)×10-9vs. (6.0±2.4)×10-9, P＜0. 05], butthere were no significant differences in the following days. With SpO2/FiO2 increasing, difference of eNO values between the HRF and non-HRF controls became narrowed, but there was still two fold difference of eNO/(SpO2/FiO2 × 100) on day 5-7. ConclusionsA method for measuring eNO was established and there was difference in neonates with and without HRF, which diminished with prolonged postnatal days, reflecting pathophysiological characteristics of HRF.

Objective To observe the expression of HER-2 and TOPO-Ⅱα in ovarian epithelial cancer,analyze the correlation between their expression and provide theoretical basis for clinical diagnosis,prognosis and treatment. Methods Expression levels of HER-2 and TOPO- Ⅱα in 10 normal ovarian tissues,20 benign tumors and 58 cases of ovarian epithelial cancers were detected by immunohistochemical method, and their correlations with pathological features were analyzed. Results The positive expression rate of HER-2 in normal ovarian and benign tumor tissues were significantly lower than ovarian epithelial cancers respectively ( 10. 0% , 15.0% VS 46. 6% ;P ＜ 0. 05 ). The positive expression rate of TOPO- Ⅱα in ovarian epithelial cancers was significantly higher than normal and benign epithelial ovarian tumor tissue (53.4% vs 10. 0%, and 15.0%,Ps ＜ 0. 05 ), but we did not find significant difference in the comparison between normal and benign epithelial ovarian tumor tissue ( Ps ＞ 0. 05 ). The expression of HER-2 and TOPO- Ⅱα were significantly correlated with clinical stages, histological differentiation of tumor cells (Ps ＜ 0. 05 ) ,but there were no correlations between the age or histological type. In ovarian cancer tissues, a positive correlation between the expression of HER-2 and TOPO- Ⅱα was observed ( r = 0. 324, P ＜ 0. 05 ) . Conclusion The overexpression of HER-2 and TOPO- Ⅱαplay an important role in ovarian carcinogenesis and development. The expression of HER-2 is positively correlated with TOPO- Ⅱα in ovarian epithelial cancers. Coexpression of the two moleculars may be involved in the development and progression of ovarian epithelial cancer, which should be further studied.
