Objective:To optimize the clarification process of total flavonoids extract from Geum aleppicum with ZTC1+1-Ⅱtype clarifying agent. Methods:With the solid removal rate, retention rate of the total flavonoids and clearance rate of protein as the indi-ces, single factor tests were adopted to study the effects of extract concentration, amount of clarifying agent, reaction temperature and reaction time on the clarification results. Results:The optimal clarification process was as follows:the extract concentration was 0. 5 g ·ml-1 , the amount of clarifying agent was 4% component B and 2% component A, the reaction temperature was at 60℃, and the soaking time was 60 min. The retention rate of total flavonoids was 91. 32%, the clearance rate of protein was 35. 82%, and the solid removal rate was 8. 1%. Conclusion:ZTC1+1-Ⅱ type clarifying agent has good effect on the clarification of total flavonoids extract from Geum aleppicum with promising feasibility and stability.

Objective To identify the animal drug of Cervus elaphs and C. nippon from origin of deers. Methods To extract DNA from deer blood and hairy antler of 11 species of deers such as C. elaphus, C. nippon and so on, and to gain the mitochondrial 12S rRNA gene fragment using the general primers of L1091 and H1478. Based on the sequence multialinement of 11 species deers above gene fragments, designing the couples of special difference primers and identifying C. elaphs and C. nippon. Results 12S rRNA Gene fragments can distinguish different deers well. The couple of primers (EP-1/H1478 and EP-2/H1478) PCR can effectively identify C. elaphus and C. nippon. Conclusion Special primer PCR is suitable for the identification of valuable Chinese medicinal materials, such as C. elaphus and C. nippon.

1.The sagittal and transverse diameters of 1,456 transverse foramina in 728cervical vertebrae were measured.The data are as follows:transverse diameter(mm) sagittal diameter (mm)Left Right Left RightMale(702 cases) 6.0?1.0 5.9?1.1 5.4?1.2 5.3?1.1Female(754 cases) 5.9?1.0 5.8?1.1 5.3?1.1 5.1?1.12.Among the 710 transverse foramina of 357 cervical vertebrae observed,mostof them are of the elliptical type.3.19.3% of double transverse foramen were found in 710 transverse foraminawhich were mostly encountered at the 6 th cervical vertebra.4.The mean value of the external diameter of the cervical part of the vertebralartery is 4?0.7mm.in 40 sides of specimens.5.63.1% of the vertebral artery in the 710 transverse foramina were foundmedial to its accompanying vein.6.According to the relationship between the sagittal(X_1)and transversediameter(X_2)of the transverse foramen and the diameter(Y)of the vertebralartery,a formula,(?)=1.859+0.172 X_1+0.24 X_2,of multiple regression was formulatedThus,the estimated diameter of the vertebral artery from the sagittal diameter X_1and transverse diameter X_2 of the transverse foramen could be obtained and it maybe helpful for clinical practice.7.In case of arthrosis,the vertebral artery could be compressed by the unco-vertebral joint which are found mostly at the level of the 4～5th cervicalvertebrae.

Objective To investigate the neuroprotective effect of lateral intracerebroventricular injection of Apelin-13 on the YAP expression and the cerebral ischemia/reperfusion (I/R) injury in Wistar rats.Methods Healthy adult male Wistar rats were randomly divided into the sham group, cerebral I/R group and Apelin-13 treatment group.The middle cerebral artery occlusion model was established with ischemia for 1 hour and reperfusion for 24 hours after restricting food and water intake for 12 hours.Apelin-13 was injected into rats' lateral ventricles of Apelin-13 treatment group after reperfusion.Neural function defects was assessed.The volume of infarction was evaluated by TTC staining.The expression levels of YAP were detected by western blot.Results Compared with the cerebral I/R group,the rats in the Apelin-13 treatment group had abetter neurologic score ((2.67±0.33) vs (1.67±0.33) , P＜0.05), the infarction volume was decreased ((30.60± 1.42) ％ vs (23.70± 2.20) ％,P＜0.05) , and YAP expression level was increased in each part of the cerebral tissue(P＜0.05).Conclusion Apelin-13 has a neuroprotective effect,which plays the therapeutic effect by regulating the expression of YAP on cerebral ischemia/ reperfusion (I/R) injury in Wistar rats.

Objective The aim of this study was to generate human cholesteryl ester transfer protein ( CETP) transgenic rabbits and analyze their biological properties.Methods We generated human CETP transgenic rabbits by DNA microinjection, and detected the expression of human CETP by real-time PCR and Western blot assay.The activity of CETP was measured using an activity assay kit.Results Human CETP transgenic rabbits were successfully generated by DNA microinjection.Compared with wide type rabbits, the expression of human CETP was dramatically increased in the liver of the human CETP transgenic rabbits.The plasma CETP activity was also much higher in the liver of human CETP transgenic rabbits than that of control rabbits.Conclusions The model of human CETP transgenic rabbits is successfully established by DNA microinjection.It will provide a useful tool for the studies of CETP biological function and its involvement in the mechanisms of cardiovascular diseases.

Objective To assess the clinical effect of Batroxobin on acute cerebral infarction. Methods Randomized controlled trials (RCTs) about Batroxobin used for acute cerebral infarction were recalled. The quality of the document were assessed with Jadad scale, and the RevMan 4.3 software was used for Meta-analysis. Results 38 RCTs were recalled. 29 trials were negatively controlled, 6 controlled with Defibrase, and 3 controlled with Urokinase. Batroxobin is more effective than negative controls on neurological function score and fibrinogen (P<0.05). There was no statistics difference between Batroxobin and Urokinase on the neurological function score (P>0.05), as well as incidence of improvement between Batroxobin and Defibrase (P>0.05). Conclusion Batroxobin can effectively improve the neurological function and reduce the fibrinogen for acute cerebral infarction.
