Objective To evaluate the effects of restraint stress on behaviors of mice with focal cerebral ischemia. Methods Male mice were first subjected to left middle cerebral artery occlusion/reperfusion. Repeated restraint stress (2 hours/day for 2 weeks) was given from 1 week after surgery. 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 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 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.

A broken metal handle accompanied by femoral trunk fracture, which would shorten service life of handles. Therefore, it is necessary to judge whether the notch is the main reason for handle broken. Some literatures thought that the pores of sintered porous coated anatomic (PCA) porous layer produce the notch on the handle surface and the notches lead to the handle broken being incorrect. The Apex of the pore is taken for the bottom of the notch, expanding into a crack, and it should also not grow to the base-alloy, accordingly, the above conclusion is wrong. Some reports pointed out the notch, apex of the pore, will expand into the crack, but it is not associated with the broken handle. Under the sintering temperature, the grain boundary apertures be generated on the base metal surface, the aperture is expanded into the crack, which leads to handle broken in the forced area. However, neither theoretical basis, nor a case of corroboration, can prove exist of notch. Actually, the broken handle is caused by the sintering technology. The high temperature of sintering joining results in grain boundary aperture, when encounter the largest forced area and expand into crack, it will break the handle.

INTRODUCTION: General joining techniques are at low level, which produces some potential problems in porous layer of porous coated anatomic (PCA).LIMITATIONS: The problems in general joining techniques are caused by limitations of each technique, which could not be solved using advanced measures.APPLICATION: The activated diffusion brazing technology is an effective way. Its many advanced processes can solve those potential problems.CONCLUSION: The stress-shielding problem caused by PCA porous layer can be solved by using small metal balls in the same diameter in combination with the advanced activated diffusion brazing technology. Moreover, the high performance brazing metals by activated diffusion brazing technology is harmless for humans.
