AIM: To observe the effects of some component of Chinese herbs for external use on proliferation of human umbilical vein endothelial cells (HUVEC) and investigate the mechanism of promoting tissue repair. METHODS: The method of MTT was used to examine the effects of Rg1, Rh1, perlolyrine, cinnamyl aldehyde, muscone, astragalus polysaccharin (APS), velver antler polypeptide (VAP) and soluble extract of boswellia carterii birdw (BCB) on proliferation of HUVEC. RESULTS: APS did not promote proliferation of HUVEC at 9.75 mg/L-2.5 g/L; Rh1 promoted proliferation of HUVEC at 1.94 mg/L-0.5 g/L (P

Objective To investigate question comprehension and production among agrammatic aphasics, and to explore the mechanisms of any dysfunction in questioning.Methods Twenty aphasics were recruited in this study.According to the Chinese Agrammatism Battery,10 were classified as agrammatic (the agrammatic group) and 10 as non-agrammatic (the non-agrammatic group).Ten normal subjects served as a control group.All the subjects were tested in terms of their comprehension and production of questions using a set of general and what-where-who- why questions (wh-questions).Results No significant difference was found between the two experimental groups with regard to the correct comprehension and production of both general and wh-questions.However,there was a sig- nificant difference in correctness between comprehension and production.The performance of the agrammatic aphasics was worse than that of the non-agramatics and the normal subjects.Conclusion The impaired question comprehen- sion and production of Chinese agrammatic aphasics has its own characteristies which can form a basis for rehabilita- tion planning and outcome prediction.

Human kerotinocyte growth factor (hKGF) gene amplified by PCR was inserted into the shuttle vector pAdTrack-CMV to get the recombinant plasmid pAdTrack-CMV-hKGF, which was linearized with Pme I and transferred into Escherichia coli BJ5183 containing the adenoviral bone plasmid pAdEasy-1 to obtain the recombinant adenoviral plasmid pAdEasy-hKGF. The recombinant adenoviral plasmid was then transfected into HEK-293 cell lines via Lipofectamine 2000 to package and amplify the recombinant adenovirus containing hKGF gene detected by PCR. The recombinant adenovirus produced could effectively infect HaCat cells. The result of Western blotting showed that HaCat cells infected with the recombinant adenovirus expressed and secreted hKGF protein.

The isolated 24 strains-producing hydantoinase & carbamoylase were first identified by Biolog microbial identification system and 16S rDNA sequence analysis.The results suggested that the hydantoinase & carbamoyalse-producing bacteria belonged to Bacillus,Geobacillus,Brevibacillus,Aneurinibacillus,Microbacterium,Pseudomonas,Kurthia and Empedobacter,and so on.Especially,Kurthia and Empedobacter were new hydantoinase & carbamoylase-producing genera.Furthuremore,it was found that D-hydatoinase & carbamoyalse-producing bacteria belonged to Pseudomonas and Agrobacterium,while most of L-hydantoinase & carbamoyalse-producing bacterial belonged to Bacillus,Geobacillus and Microbacterium.The distribution feature of D-hydantoinase & carbamoyalse-producing bacteria and L-hydantoinase & carbamoyalse-producing bacteria showed some genera tendency.This research work will provide the biomaterial of different hydantoinase and carbamoylase and contribute to study the structure and function,molecular evolution of the two enzymes.

Objective To investigate the prognostic factors for chronic heart failure and the prognostic ability of copeptin,big endothelin-1(Big ET-1)and N-terminal pro-brain natriuretic peptide (NT-proBNP)in patients with chronic heart failure. Methods To study 1 5 9 consecutive patients hospitalized for chronic heart failure.Serum concentration of copeptin,NT-proBNP,cTnI,CKMB and plasma Big ET-1 as well as left ventricular ejection fraction (LVEF)and NYHA classⅠtoⅣ on admission were measured.Cardiac events were found by patients to discharge after 360~490 days,prospectively.Results During a median follow-up period of 385 days,the endpoint of recurrence for cardiac events was reached in 65 patients with 159 heart failure.Multivarlate canonical correlation analysis shows the older and the higher NYHA classification as well as the lower LVEF in patients with heart failure.There were higher concentration of copeptin,Big ET-1 and NT-proBNP.On a Cox proportional hazards regression models analyses,age,copeptin,Big ET-1 and NT-proBNP were found to be the inde-pendent predictors of cardiac events.Risk ratio (RR)were 1.215,1.236,4.031 and 13.052,respectively.Logistic regression models analyses,copeptin,Big ET-1 and NT-proBNP were found independent predictors of death.Odd ratio (OR)were 4.003,2.477 and 1.235,respectively.Conclusion Measurement of copeptin,Big ET-1 and NT-proBNP in patients with chronic heart failure can help to identify patients at higher risk for cardiac events and patients for prognosis.

Objective To observe the effects of electro-acupuncture ( EA ) on learning, memory and the morphology of hippocampal neural tissues in rats with a model of chronic cerebral ischemia.Methods One hundred and twenty male Sprague-Dawley rats were used. Chronic cerebral ischemia models were successfully established in 104 of them, and those rats were randomly divided into an EA group and a model group with 52 rats each. These were further subdivided into 1,2, 4 and 6 week subgroups with 13 rats in each. The EA group was given EA. The changes in spatial learning and memory ability were observed using a Morris water maze. The morphological changes in hippocampal nerve tissue were observed by HE staining.Results The escape latency in the EA group was significantly different from the model group at the 2nd, 4th and 6th week. The nerve cells in the dentate gyrus were more tightly and consistently lined-up and had rich layers, and the structures in the EA group were better than in the model group.Conclusions EA can improve spatial learning and memory and promote the repair of injury after cerebral ischemia.

Objective To investigate the protective effect of heme oxygenase-1 (HO-1)/carbon monoxide (CO) system on restenosis after balloon angioplasty and relative mechanism. Methods Fifty rabbits were randomly divided into 5 groups. Control group received normal chow (Control group), the other rabbits received 1.5% cholesterol diet (Chol group and SH group) or 1.5%cholesterol diet plus hemin (Hem group) or zinc protoporphyrin Ⅸ (Znpp group) for 10 weeks. At the third week of experiment, the three experimental groups underwent balloon injury at one side common carotid artery. Results Compared with control group, arterial nitric oxide production and nitricoxide synthase activity were significantly decreased, while HO-1 expression and CO production were significantly increased (all P<0. 01 ) in Chol group. The intima thickness and ratio of intima/media (I/M) were lower in Hem group than in Chol group [(281.47± 21.10) μm vs. (442.17 ±59.14) μm, 2.49 ± 0. 17 vs. 3.99 ± 0. 52, respectively]. While arterial HO-1 expression and CO production were increased markedly, endothelin-1 expression was distinctly reduced in Hem group group than in Chol group. Compared with Chol group, arterial HO-1 expression and CO production were decreased obviously, while endothelin-1 expression and intima thickness and ratio of intima/media [(698.71±58. 37) μm, 6.17±0. 52]were significantly increased in Znpp group (all P<0. 01).Conclusions The HO-1/CO system plays a protective role on improving endothelium function and restraining neointimal proliferation by compensating and regulating nitricoxide synthase/nitric oxide system and lowering endothelin -1 expression so as to inhibit restenosis after balloon injury.
