At the end of stress scheme, sucrose solution consumption test, open-field test and forced swimming test were performed. Results Spontaneous locomotor activity and coordination test were decreased to the lowest level on the 1st day after MCAO compared with the baseline values before surgery (P

The study of quality control of Chinese medicine has always been the hot and the difficulty spot of the development of traditional Chinese medicine (TCM), which is also one of the key problems restricting the modernization and internationalization of Chinese medicine. Multivariate statistical analysis is an analytical method which is suitable for the analysis of characteristics of TCM. It has been used widely in the study of quality control of TCM. Multivariate Statistical analysis was used for multivariate indicators and variables that appeared in the study of quality control and had certain correlation between each other, to find out the hidden law or the relationship between the data can be found,.which could apply to serve the decision-making and realize the effective quality evaluation of TCM. In this paper, the application of multivariate statistical analysis in the quality control of Chinese medicine was summarized, which could provided the basis for its further study.

Objective To explore the role of p170, MRP, bcl-2 in clinical drug- resistance and their correlation. Methods There are 44 acute leukemia(AL) patients, among them ANLL is 29, ALL is 15.The expression of p170, MRP, bcl-2 were detected. At last, the patients were divided into two groups: CR and NR according to efficacy after two periods standard chemotherapy. Results Overexpression of p170, MRP,bcl-2 were found in AL (P ＜0.05). The expression of p170 and MRP were lower in CR group than that in NR groups in AML and ALL; there were 22 of 24 patients expressed one or two proteins in NR groups and the expression of p170 in patients was concordant with that of MRP to certain extent (P ＜0.01). The overexpression of bcl-2 was related with the worse prognosis. The expression of bcl-2 was lower significantly in CR group than in CR and NR (P＜0.05). Conclusion p170, bcl-2, MRP are all associated with clinical MDR. High expression of these proteins is an unfavorable factor to prognosis. The expression of MRP and p170 showed coincidence, but showed no significance with expression of bcl-2 in untreated patients, it indicated that the drug-resistance mediated by p170 was different from bcl-2.

Objective To observe the effect of acupuncture and herbs on risk factors and prognosis of transient ischemic attack (TIA).Methods 120 patients received treatment from March to May 2011 in Gaomi People's Hospital and the Hospital of Gaomi were randomly divided into three groups,with 40 cases in each.Acupuncture and Chinese medicine group was treated with needling Neiguan and administered with modified Tianmagouteng decoction,3 times/d; Chinese medicine group was treated with modified Tianmagouteng diction exclusively,3 times/d; Western medicine group was treated with Aspirin,0.1 g,1 times/d.The three groups were treated for 30 d of two therapeutic courses.TCM syndrome score,blood pressure,blood lipids,blood rheology,blood sugar changes in the three groups of patients were observed before and after the treatment.And follow-up of elapse rate and the incidence of stroke in a year were observed.Results After treatment,① in the acupuncture and Chinese medicine group: the total cholesterol was (5.21 ± 0.97)mmol/L,whole blood viscosity was [(4.26±0.66) 200 mPa · s,(5.69±0.15) 30 mPa · s,(9.72±2.33) mPa · s],fibrinogen was (2.12± 0.46)g/L,systolic blood pressure was (124.13±9.96) mm Hg,diastolic blood pressure was (79.23±7.50) mm Hg,blood glucose was (5.59 ±0.78) mmol/L; in the Chinese medicine group,the total cholesterol was (5.43± 1.04) mmol/L,whole blood viscosity was [(4.25±0.25) 200 mPa · s,(5.46±0.55) 30 mPa · s,(9.81± 2.01) 5 mPa · s],fibrinogenwas (2.32±0.33) g/L,systolic blood pressure was (129.78±14.25) mm Hg,diastolic blood pressure was (79.54± 7.65) mm Hg,blood glucose was (5.60± 0.75) mmol/L; in the western medicine group,the total cholesterol was (5.52± 1.16) mmol/ L,full blood viscosity was [(4.12±0.54) 200 mPa · s,(5.45± 0.65) 30 mPa · s,(9.09 ± 1.11) mPa · s],fibrinogen was (2.41 ± 0.44) g/L,systolic blood pressure was (129.83 ± 14.91) mm Hg,diastolic blood pressure was (80.72±7.47) mm Hg,blood glucose was (5.75 ± 0.61) mmol/L.all these results were improved significantly than those before the treatment in the same group (P＜0.05),and the acupuncture and Chinese medicine group improved better than the other two groups (P＜0.05).② In 1-year follow-up,TIA recurrence rate of stroke in the acupuncture group were lower than the other two groups.Conclusion Acupuncture and Chinese medicine treatment were not only be able to improve the clinical symptoms of patients with TIA and blood pressure,blood lipids,blood theology,blood sugar and other risk factors for TIA patients significantly,but also can effectively reduced the relapse rate and the incidence of stroke.

Objective To investigate the prevalence and symptoms of post - traumatic stress disorder(PTSD) and the self-esteem of the workers at mineral processing plant 45 days after Wenchuan earthquk. Methods PTSD Checklist Civilian version(PCL - C) , Self -Esteem Scale(SES) , Simplified Coping Style Questionnaire and a self- designed questionnaire were administered to a sample of 81 workers one and a half month after Wenchuan earthquake. Results The prevalence of PTSD among the workers was 26.3% , and the mean total scores of PCL - C was 39.63?10.73.The prevalence difference between the male and the female was not statistically significant (P =0.527). The top psychological activity was worry (86.8%). The mean self- esteem score had no statistical difference with domestic normal level(t = -0.484,P =0.630). Neither self - esteem(P =0.469) nor coping style(P =0.780) was associatied with PCL -C total scores. Conclusion To act more effectively in the intervention, it is important to exactly understand the normal stress response after severe disaster, and correctly grasp the key point in different stage.
