AIM: To establish a method for determination of schizandrol A in Mian'er'an Dripping Pills (Semen Ziziphi Spinosae, Fructus Schisandrae, etc.). METHODS: HPLC was used with hypersil C 18 column (250mm?4.6mm; 5?m), methanol water (65∶35) as a mobile phase and detection wavelength at 254nm. The flow rate was 1.0mL?min -1 and at room temperature. RESULTS: The calibration curve was linear (r= 0.9999). The average recovery was 100.2% and RSD was 2.9%, respectively. CONCLUSION: The method is simple, quick and specific, and provides a quality control for the dripping pills.

Lappaconitine (LA) 0. 5 mg? kg-1had significant antagonistic action on the ar-rythmia induced by 3-acetylaconitine ( AA ) 0.07 mg?kg-1in rat. When LA and AA were used in combination (7:1) in mice, the analgesic activity of AA was not influenced marked-ly by LA but the LD50 of AA was increased by 50% ,therefore the therapeutic index of AA was increased and the margin of safety was widened.

ObjectiveTo investigate the protection of extract form earthworm a traditional Chinese medicine in auricle microcirculation disturbance in mice. MethodThe microcirculation disturbance in mice was brought by rapid injection of high molecule dextran. Observe the microvascular diameter,the blood flow speed,the blood fluid state and crossing net patency quantity of micrangium in mice before injection and after injection 10min,20min,30min with WX-9 microcirculation microscope and analytical system. ResultHigh and low dose of extract form earthworm could expend the diameter of the vein and artery of micrangium, quicken the blood flow speed,improve the blood fluid state,increase micrangium crossing net patefaction numbers. To compare with the control group, threr’s significant difference (P

Objective:To investigate the pain in patients during the early stages of recovery from maxillofacial surgery under general anaesthesia.Methods: One hundred patients as participants to respone the questionaire of postoperative pain 24 hours after operation. The data of pain intensity,analgesia requirement and the reason for operation of the patients were collected and analyzed. Results: Among the 100 cases, 92 with moderate or slight postoperative pain, 8 with severe pain. It is significant more severe pain (14.3%)in the group of bone fracture than that (less than 8.7%) in other groups. Conclusion: Most patients 24 h after maxillofacial surgery are with moderate and slight pain. The pain intensity relates with type of maxillofacial surgery.

The construction of the model curricula is the important branch of teaching quality engineering. The key to the development of the model curricula lies in the reform of the teaching model. As required to the national standards of the model curricula and to the purpose of innovative educational philosophy,with the years of continuous exploration and practice,the clinical immunology examination curriculum has kept developing from the teaching staff,teaching condition,content of course,teaching method and means etc.,which has brought about satisfactory teaching effects. Thus it is forming the model curricula with special features.

Comparative medicine is a synthetical subject,to provide protection and improve healthy medicare of human being by studying all kinds of human diseases using laboratory animals.Comparative medicine is widely involved in training medical talents,elucidating disease mechanism,improving medicare level and benefiting human healthy services.Therefore,comparative medicine research is an important foundation of medicine development,and indispensable supporting condition and organic compartment in all-round development of "medication,education and research" in modern comprehensive hospital.

ObjectiveTo investigate the influence of gender and psychosocial parameters on the quality of life in patients with irritable bowel syndrome(IBS). MethodsOut-patients from Jan to Oct 2008 in the Department of Gastroenterology at the First Affiliated Hospital of Nanjing Medical University were enrolled. Based on Rome teria IBS was diagnosed. Interviewed by a GI physician with questionnaire of demographic data,Zung self-rating anxiety and depression scale(SAS/SDS) and IBS-specific quality of life(IBS-QOL) questionnaire. Results452 patients were diagnosed as IBS according to Rome Ⅲ criteria. IBS was more common in female. In male, anxiety and depression scales were significantly increased( t =7. 191、6. 459 ,P ＜ 0. 01 ) and the scale of IBS-QOL was significantly decreased ( t =9.119, P ＜ 0.01 ) in female IBS patients. In IBS patients, IBS-QOL scales were negatively associated with the anxiety and depression scales(P ＜0. 01 ). ConclusionThese results suggest that there were gender differences in psychological status and quality of life in IBS patients,and difference psychological status based on gender should influence the quality of life of patients with IBS.

Background Tumstatin is the most active endogenous angiogenesis inhibitor,which has a marked inhibitory effect on pathological neovascularization,and Tum5 is an angiogenesis inhibitors fragment of fulllength tumstatin.Objective This study was to investigate the effects of adenovirus-mediated overexpression of recombinant Tum5 gene on the proliferation,migration and tube formation of human umbilical vein endothelial cells (HUVECs) in physiological status.Methods The empty adenoviral vector expressing green fluorescent protein (rAd-GFP) and the viral vector expressing recombinant Tum5 gene were constructed.The HUVECs cultured in RPMI1640 medium were divided into normal control group,empty vector group (rAd-GFP group) and Tum5 gene infection group (rAd-GFP-Tum5 group).The rAd-GFP and rAd-GFP-Tum5 adenoviral particles at the density of 1 × 1010/ml were added into the medium to infect the cells for 48 hours.The proliferation of the cells was assayed at 24,48 and 72 hours by cell counting kit-8 (CCK-8) to evaluate the proliferative rate;the migration number of the cells was detected at 48 hours after infection by Transwell chamber;the tube formation number of the cells were detected by Matrigel method.The concentration of vascular endothelial growth factor (VEGF) in cell supernatants was assayed by ELISA at 24,48,and 72 hours following adenoviral infection.Results The cultured cells showed green fluorescence in the rAd-GFP group and rAd-GFP-Tum5 group under the inverted fluorescence microscope,and the infection efficiency of rAd-GFP and rAd-GFP-Tum5 was 55.13％ and 50.31％,respectively.No significant difference was found in cell proliferative rate among normal control group,rAd-GFP group and rAd-GFP-Tum5 group both at 24 and 48 hours after infection (both at P＞0.05),and the cell proliferative rate was significantly lower in the rAd-GFP-Tum5 group than that in the normal control group and rAd-GFP group at 72 hours after infection (both at P＜0.01).The migration number of the cells at 48 hours after infection was 2 260.25-±930.44,2 370.00±441.06 and 723.75± 363.80 in the normal control group,rAd-GFP group and rAd-GFP-Tum5 group,showing a significant difference among the groups (F =8.524,P =0.008),and the migrated cells were evidently decreased in the rAd-GFP-Tum5 group compared with the rAd-GFP group and the normal control group (both at P＜ 0.01).The tube number at 48 hours after infection was 95.67±5.86,88.00±4.58 and 20.67±3.51 in the normal control group,rAd-GFP group and rAdGFP-Tum5 group,showing a significant difference among the groups (F=226.498,P＜0.01),and the tube number in the rAd-GFP-Tum5 group was significantly reduced in comparison with the normal control group and rAd-GFP group (both at P＜ 0.01).The considerably differences in VEGF concentration in the cell supernatants were found in different groups and various time points (Fgroup =73.260,P＜0.01;Ftime =73.477,P＜0.01),and VEGF concentration in the cell supernatants was significantly decreased in the rAd-GFP-Tum5 group compared with the rAd-GFP group at both 48 hours and 72 hours (both at P＜0.01).Conclusions The overexpression of the recombinant Tum5 can inhibit the proliferation,migration and tube formation of the HUVECs in physiological status,which may be associated with Tum-5-mediated down-regulation of VEGF protein in the cell supernatant.
