Objective To investigate the influence of Buyanghuanwu (BYHW) Decoction on cerebral infarct volume and pathological changes after cerebral ischemia and reperfusion. Methods The model of focal cerebral ischemia and reperfusion was made by thread embolism method. Healthy male SD rats were divided randomly into sham-operated group, model group and BYHW Decoction group. Infarct volume was detected by triphenyltetrazolium chloride (TTC) staining and pathological changes were observed microscopically in HE stained sections. Results In BYHW Decoction group, infarct volume was significantly smaller than that in model group (P

0.05).The exclusion probability of Gc is 34.8% and discrimination probability of Gc is 79.44%.There are not any significant difference of the distribution of Gc subtypes between the Hun population in Chengdu and those in Hong Kong and Japanese.The difference of the distribution of Gc subtypes between the Han population in Chengdu and those in Malaysia,Indonesia,India as well as the American caucasians,Belgians,Icelander and West German are sig- nificant. The phenotyping of Gc in 11 bloodstain samples kept in room temperature for twenty weeks were carried out successfully also using PAGIF followed by immunofixation method.

Aortopulmonary septal defect is a rare anomaly,it should be considered whenever the course of complex congenital heart di-sease includes early cardiac failure and pulmonary hypertension.So the importance of early correction to avoid irreversible pulmonary hypertension was emphasized.Noninvasive imaging with echocardiography and (or) 64MRSCT will adequately define the anatomy before surgery,it's necessary to perform cardiac catheterization to evaluate the reversability of pulmonary vessels when pulmonary hypertention is suspected.

More and more research proved that CD4+CD25+ regulatory T cells (Treg cells) play an important role in immune tolerance in these years. Known as a T cell growth factor, Interleukin2 (IL-2) regulated the immune tolerance induced by Treg cells. IL-2 sustained the activity of Treg cells both in thymus and periphery while it was dispensable for the development of Treg cells in thymus. In addition, IL-2 signal affected the function of Treg cells and maintained their competitive fitness. Therefore, CD4+CD25+ Treg cells and IL-2 formed an immune network to regulate the processes of immune response, immune tolerance and autoimmune homeostasis.

Objective: To evaluate the effect of roughness on adhesive properties of polymethyl methacrylate and SY-1 silicone elastomer.Methods:5 specimens of polymethyl methacrylate were polished by sand paper of different standards and the roughness of polymethyl methacrylate surfaces were measured by roughmeter. The tension strength between polymethyl methacrylate with different degrees of roughness and SY-1 silicone elastomer were tested according to national standards. Results: After the surfaces of polymethyl methacrylate were respectively polished by sand paper of the standard 160,320 and 800, the sufrace roughness decreased, but the tension strength between polymethy1 and SY-1 silicone elastomer was increased(P

Objective To investigate MVD, TSP-1, TGF-?1 expression in GH-Secreting Pituitary Adenomas by immunohistochemistry, and to correlate data with clinical characteristics.Methods The protein expression of TSP-1, TGF-?1 in 48 surgical specimens (21 invasive cases; 27 non-invasive cases) of pituitary adenomas was measured using immunohistochemical method. The relationship between the expression and clinical properties was examined. MVD was measured by detecting CD34.Results Compared with the noninvasive group, no difference of expression of CD34(t=2.257; P=0.083) was observed. The expression of TSP-1 in invasive group was low. The expression of TGF-?1 was higher in invasive cases than that in noninvasive ones. The expression of TGF-?1 had positive correlations with MVD; but there was no correlation between the expression of CD34 and the invasion of pituitary adenomas. In addition, MVD count was not associated with the expression of TSP-1. Size, sex or rate of recurrence did not influence MVD and TSP-1 expression. Conclusion MVD values do not necessarily represent angiogenesis in pituitary adenomas. TGF-?1 may increase MVD, and TSP-1 does not affect MVD in pituitary adenomas and angiogenesis may be regulated by other pathway.

Objective To study the biological function of Topical Oxygen Therapy(TOT) and Infrared Light-Emitting Diode(LED) therapy and mechanism of combination of both therapy in wound healing.To develop a device combined with TOT and LED therapy.Methods Wound models were made using rabbits which were grouped in four groups such as control group,TOT group,LED group and combined group by random.Except control group,the other groups were carried on TOT,LED and TOT+LED therapy respectively.Wound healing situations were observed.Results TOT+LED therapy could cut the wound healing time whose mechanism was to form composition force in the processing of wound healing by prompting inside growth factors and outside factors.Conclusion The therapy combined with TOT and LED can facilitate the wound healing.The theory of the wound healing device is feasible according to the results of the experiments.

Objective To establish the disease-syndrome integrated animal models suitable for the studies of TCM through differen- tiating the property of TCM syndromes of spontaneous diseased animal models.Methods With the observation on general behaviors, irritable degree,turning endurance time,pain threshold,urine and stools,luster of hair,growing speed of hair,body weight,tongue condition,degree of eyeball protruding,conjunctiva chroma,blood pressure,heart rate,etc.of spontaneous hypertension rats(SHR) and the comparison with normal rats,the study was carried out on the macroscopic description of property of TCM syndrome of SHR (14～18 weeks of age)and their ethology.Results The blood pressure of SHR at the early stage tended to raise with age growing. Compared with the normal group,the heart rate of SHR rats was obviously quicker(P

In observing the therapeutic efficacy of insulin sensitizer in treatment of early T2DM,120 T2DM patients were randomly divided into 3 groups: group A received 4 mg rosiglitazone daily;group B received 1.5 g metformin daily;group C received 4 mg rosiglitazone and 1.0 g met-formin every day.Before and after the treatment,fasting glucose,HbA1c,weight,adiponectin,BMI and HOMA-IR were measured or calculated.We found that fasting glucose,HbA1c and HOMA-IR of 3 groups were obviously decreased in comparison with their baseline and adiponectin was significantly increased.In conclusion,insulin sensitizer can obviously decrease the levels of glucose,HbA1c and HOMA-IR,and increase the level of serum adiponectin in T2DM.Insulin sensitizer in combination of metformin is suitable for treatment of T2DM.

Based on the study of four diagnostic methods in Treatise on Exogenous Febrile Diseases,this dissertation analysed the cause of differentiation of syndrome unavailable,and indicated that:differentiation of syndrome unavailable resulted from multi-reasons.The patients who had symptoms and signs but all the modern physics and chemistry index were normal,the data get from traditional four diagnostic methods were useful to discriminate and estimate diseases.Modern physics and chemistry index can help in improving exactitude,but we cannot ignore traditional diagnostic methods.
