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.

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.

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.

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

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.

OBJECTIVE:To study the bio-equivalence of domestic loratadine syrup and tablets in human beings.METHODS:a dose fo40mg domestic loratadine(syrup or tablet)was given to18healthy male volunteers to a randomized crossover design.Blood samples were collected before administration and20min,40min,1hr,1.5hr,2hr,3hr,4hr,6hr,8hr,12hr,24h after administration.The concentrations of Loratadine in blood were determined by HPLC.Pharmacokinetic parameters and relative bio-availability were detected with3p97program.RESULTS:The main pharmacokinetic parameters of domestic Lortadine syrup and tablet were as follows:C max were(40.91?15.42)ng/ml and(41.57?18.68)ng/ml respectively;T max were(1.04?0.19)h and(1.19?0.25)h respectively;T 1/2 were(4.43?1.67)h and(4.21?1.49)h respectively;AUC 0～24 we_ re(127.60?46.28)(ng?h)/ml and(133.13?45.65)(ng?h)/ml respectively;AUC 0～∞ were(132.98?47.43)(ng?h)/ml and(138.16?47.26)(ng?h)/ml respectively.The relative bio-availability was(96.25?21.30)%.CONCLUSION:the do?mestic Lortadine syrup and tablet are bio-equivalent.

AIM: In order to investigate the possible cumulative and chronic toxicity of paralytic shellfish poisoning (PSP) and provide more information on toxicity of PSP. METHODS: The sub-acute toxicity of PSP was evaluated in the rat. PSP was extracted from the seafood in market, and the toxicity of the extract was determined by mouse bioassay. The extracts in different toxicity were administrated to rats through gastrotube for 35 days. The biochemical and pathological changes in vital tissues in rats were examined by the detections of some function indexes in blood and urine and the observations under optical microscope during both the exposure period and the subsequent 10-day withdrawal term. RESULTS: No biochemical and pathological changes in tissues occurred for the control and low-dose group (4.6 ?g STX/kg), whereas some changes happened for the middle (9.2 ?g STX/kg) and high groups (18.4 ?g STX/kg). In experiment, some renal function indexes changed in the mid-dose group, and some of the cardiac, hepatic and renal functions indexes altered for the high dose group with some changes in weight of the thymus gland and spleen. What is more, the liver and kidney became indistinct with some inflammatory changes, and some muscles had ruptured for the 40% rats in high-dose group. CONCLUSION: These results suggest that long-term intake of PSP at a concentration, which doesn't exceed the threshold of standard, has some toxicity on rats, and that the toxicity of PSP has an accumulative effect. In a word, it is unsafe for us to eat frequently bivalve seafood polluted by PSP toxins.

The culture of modern medical talents is the requirements of the times on cultivating talents of Medical Laboratory of Medical College. In order to establish a high level teaching team and im-prove the quality of teaching and personnel training, through the reform of the traditional teacher training way, we created the teacher training mode of multi echelon teachers including department, university, domestic and international training ways. New curriculum teaching system framework was established which was based on theoretical teaching, practical teaching and scientific research. Besides, innovative and pro-gressive practice teaching platform was set up which included basic experiment, clinical skills, professional training, and practice in company. Course of Clinical Examination Skills was opened. The teaching team achieved some results in the above teaching reform.
