OBJECTIVE:To investigate new thought and method for improving the practice teaching effect of pharmacy under-graduates under the collaboration of medicine and education. METHODS:The training objectives of pharmacist team,the current sit-uations and problems of teaching that existing in the institute of pharmacy and the requirement of talents in the work were summa-rized and investigated,and then reform targets and measures were put forward. RESULTS:Training for pharmacists tream gradual-ly movedcloser to clinical pharmacists in China.The teaching work in the pharmacy department of our hospital was relatively com-plete,including relevant teaching system,practice systems and processes,training program for clinical pharmacists and develop-ment of workflow;however,there still remained some problems,including lacking of professional quality training,suitable cours-es,effective interactive medical and education scientific assessment mode and no attention for the training of clinical thinking and school-university research thinking. The above-mentioned problems needed to be solved by reforming internship tutorial system and improving the contents,establishing the school-hospital united system,emphasizing the connection between schools and teaching bases,establishing integrated teaching evaluation system and assessment criteria,strengthening clinical experience and training for clinical thinking by the teaching mode of physicians and pharmacists. CONCLUSIONS:Strengthening the collaboration of medicine and education and improving the training standards and evaluation system are helpful for improving the practice teaching quality of pharmacy undergraduates.

To investigate the neuroprotective of ligustilide (LIG) against glutamate-induced apoptosis of PC12 cells, cell viability were examined by MTT assay. Flow cytometry was applied to assay cell apoptosis rate. Intracellular calcium concentration was measured by using fluorescent dye Fluo-3/AM. Cytochrome C (Cyt C), Caspase-3, Bax and Bcl-2 protein expression were assayed by western blot. The results showed that glutamate is cytotoxic with an inhibitory concentration 50 (ID50) of 15 mmol · L(-1). Pretreatment with LIG (1, 5, 15 μmol · L(-1)) significantly improved cell viability. The apoptosis rate in glutamate-induced PC12 cells was 13.39%, and decreased in the presence of LIG (1, 5, 15 μmol · L(-1)) by 9.06%, 6.48%, 3.82%, separately. Extracellular accumulation of Ca2+ induced by glutamate were significantly reduced by LIG. The results of western blot manifested that pretreatment LIG could decrease the release of Cyt C from mitochondria, down-regulate Caspase-3 protein expression and up-regulate Bcl-2/Bax ratio, thereby protects PC12 cells from apoptosis. In summary, LIG had protective effect on glutamate-induced apoptosis in PC12 cells through attenuating the increase in intracellular Ca2+ concentration, and inhibiting the release of Cyt C from mitochondria to cytoplasm.

Pharmaceutical market is a typical market with information asymmetry, and which can lead to "lemons" problem. In all developed countries, firms must receive regulatory approval to market a pharmaceutical product. Such administrative department including SFDA, EMA, FDA and so on. Chinese materia medica is a special part of pharmaceutical market in China. The management of Chinese materia medica is a special challenge in China.

OBJECTIVETo observe the effects of acupuncture at "Tianshu" (ST 25) on electro-activity and mechanical motility at different phases of migrating motor complex (MMC) during jejunal digestion period in rats with detached jejunum, so as to explore the effect and mechanism of acupuncture on regulating intestinal movement.
METHODSSixteen adult SD rats were selected. Electrodes were implanted in the serous membrane of intestinal smooth muscl.e and high-sensitivity sensors of strain gauge were sutured on serosal surface, and then the rat was anesthetized and its jejunum was detached. Electro-acriviry and mechanical motility of jejunal smooth muscle were recorded simultaneously. Acupuncture was applied at "Tianshu" (ST 25) at MMC I , MMCII and MMC III, respectively, to observe its influence on electro-activity and mechanical motility.
RESULTSAt phase of MMC I, there was no obvious change of the fast wave before and after the acupuncture, while the frequency and amplitude of slow wave and mechanical motility were both significantly decreased compared with baseline (P < 0.01). At MMCII-Ill, the frequency and amplitude of fast wave, slow wave and motility were all significantly decreased compared with baseline (P < 0.01). Acupuncture at "Tianshu" (ST 25) had prohibited effects on electro-activity and mechanical motility of jejunal smooth muscle in rats with detached jejunum.
CONCLUSIONAcupuncture at "Tianshu" (ST 25) has obvious prohibited effects on electro-acrivity and mechanical motility at MMC I , MMC II and MMC III time phases in rats with detached jejunum. The possible mechanism is that acupuncture at "Tianshu" (ST 25) could prohibit jejunum movement through reflex path of skin-sympathetic.

Objective To investigated to implement condition of preventive measure and control effect for endemic fluorosis in Fengshun County from 2005 to 2006.Methods It was investigated according to the National Surveillance Program of Endemic Fluorosis.Hupo,Daizai and Anquan Villages of Tangxi Town in Fengshun County were selected as monitoring spots.The usage of reforming water facilities,fluoride content in drinking water and urine of children aged 8-12 years and the prevalence rate of dental fluorosis of children were investigated.Resul tsin 2005 and 2006.a total of 18 reforming water facilities were surveyed and six of which were damaged or out of service.In 2005,the fluoride content in drinking water in the 3 villages was 2.10,1.22 and 0.15 mg/L The prevalence rate of dental fluorosis of children aged 8-12 years was 54.23%(64/118),38.91%(79/203) and 9.10%(6/66).The urine fluoride content of children was 0.95,0.90 and 1.05 mg/L,respectively.In 2006,the fluoride content in drinking water in Hupo,Daizai and Anquan Village was 2.01,1.57 and 0.21 mg/L.The prevalence rate of dental fluorosis of children aged 8-12 years was 26.47%(27/102),12.50%(23/184)and 6.15%(4/65),respectively.The urine fluoride content of children was 0.97,0.61 and 0.59 mg/L.Conclusions The outcome of surveillance data in Fengshun County has reached the sanle level as that of non-disease area.However,the management of reforming water facilities should be improved.

Objective To review the surgical managements of patients with traumatic false aneu- rysms in the extremities.Methods From January 1990 to April 2006,17 patients with traumatic false aneurysms in the extremities were admitted into our hospital.Fourteen patients were treated by vascular repair including vascular repair in seven cases,end to end anastomosis in one,synthetic grafting in one, autogenous vein grafting in one,and direct ligation in four.Three patients were treated nonoperatively, but with local compressive dressing.Results There were no deaths or gangrenes in all cases.The clinical manifestations vanished after the treatment.The mean follow-up period was 13.2 months.The function of the injured extremities recovered satisfactorily.Conclusion Different types of traumatic false aneurysms should be managed by different therapeutic procedures after the diagnoses is made.

Objective To analyze our clinical results of head and neck reconstruction using microsur- gical free flap transfer techniques.Methods The free flap donor sites with long vascular pedicle and large diameter of vessel were routinely chosed,and chose receipt vessels with large diameter and proper position, and perform vessel ananstomosis under surgical loups instead of microscope.The un-buried free flap with a mo- nitoring window were harvest,and do double venous anastomoses in some flaps to ensure adequate venous out- flow.Results From May 1999 to March 2005,1066 consecutive free flap transfers were used to reconstruct head and neck defects.The overall success rate of free flap was 98.3%.The vessel thrombosis rate was 3.1%,and the flap salvage rate was 45.5%.Conclusion Head and neck reconstruetion using microsurgi- cal free flap transfer technique is safe and reliable,and good clinical results can be obtained.

0.05); serum HBsAb levels of pregnant mice and neonatal mice in group with CpG-1826 (20 ?g)+hepatitis B vaccine significantly higher than those in group with CpG-1826 (10 ?g, 40 ?g)+ hepatitis B vaccine,hepatitis B vaccine and control respectively(P0.05).Conclusions Combination injection of CpG-1826 20 ?g and hepatitis B vaccine can markedly increase serum antibody levels of pregnant mice and neonatal mice, but don′t affect the survival quantity, the growth and development of neonatal mice.CpG-1826 is an ideal immune adjuvant for neonates with immature immune system during pregnancy.
