Objective To investigate effect of decorin on proliferation and cell cycle of rabbit tendon cells in vitro so as to explore the role of decorin in tendon wound healing.Methods Tendon cells derived from the tissue of rabbits flexor tendon were harvested and cultured in vitro with decorin of 0.25,1.25,2.5,5 ?g/ml.After culture of 12,24 or 48 h,the cell proliferation rate was measured by MTT colorimetric determination.After 24-hour culture with 0.25?g/ml decorin,the morphology of tendon cells was obtained and the cell cycle distribution was detected by flow cytometer.Results The proliferation of tendon cells was inhibited after 12-hour culture and significantly increased after 24-hour culture with 0.25,1.25,2.5 ?g/ml decorin.However,5 ?g/ml decorin could increase the proliferation after 12-hour culture,increase after 24-hour culture,with no significant difference between 24 h and 48 h.decorin at 0.25 ?g/ml could significantly increase the cells at S phase and PI after 24-hour culture(P

Objective To investigate the brain protective effects of isoflurane preconditioning for local cerebral is-chemia adult rat model by detecting HIF-1α, HO-1 and Bcl-2 expression level. Methods 84 two-month old Spra-gue-Dawley male rats were randomly divided into sham group, ischemia-reperfusion group ( MCAO group) and isoflurance preconditioning group (ISO group). ISO group was exposed to isoflurane for 30 min and then underwent a 90 min middle cerebral arterial occlusion (MCAO), while MCAO group underwent MCAO only. At 24 h after reperfusion all the groups were investigated by modified neurological severity score for neurological deficits, TTC staining for infarct percentage. Cerebral cortices were harvested for HIF-1α, HO-1 and Bcl-2 protein expression level detection at 6 h, 24 h and 72 h after reperfusion using RT-PCR and western blot. Results The mNSS score and infarct percentage in ISO group decreased significantly compared with those of MCAO group at 24 h after reper-fusion(P < 0. 05). Compared with the MCAO group, ISO group had significantly up-regulated protein levels of HIF-1α, HO-1 and Bcl-2 at 6 h and 24 h after reperfusion(P < 0. 05). There was no difference between ISO group and MCAO group for 3 gene expression at 72 h(P > 0. 05). Conclusion Isoflurane preconditioning plays short-term cerebral protective effect through the up regulation of HIF-1α, HO-1 and Bcl-2 gene expression.

Objective To explore the practical method and teaching effect of problem-based learning (PBL) pattern in teaching of gastrointestinal disease for seven-year-program students during their internal medical probation.Methods The traditional pattern (gastrointestinal diseases) and PBL pattern (hepatobiliary diseases) were applied in these students to assess the teaching effects by exam scores and questionnaire.Results ① There was no significant difference between traditional training and PBL by exam scores (P>0.05).② The PBL approach was widely accepted by students,which could contribute to the improvement of their learning motivation.It developed skills,including self-directed learning,summarizing,and clinical thinking capability and so on.Conclusion The PBL approach is a practical learning strategy that can improve the teaching effect; therefore it should be wildly practiced in future works.

Objective To study the effect o f levamisole against the invasion of Schistosoma japonicum cercariae. Methods Mice infected wit h Schistosoma cercariae were administered orally with levamisole hydrochloride or alkali levamisole two days before the infectio n at a dose of 26.25 mg/kg for 7 days. The liniments of levamisole hydrochlorid e and alkali levamisole were embrocated on the mouse skin two days, one day and 0 day before the infection respectively, and the concentrations of the drug were 1%, 2%, 3%, 5% and 7% respectively. The experimental animals were dissected 4 we eks after the treatment and adult worms were collected. Results The worm reduction rates of mice administered orally with leva misole hydrochloride or alkali levamisole were both 0. The worm reduction rates were both 100% when the mice were embrocated with 5% levamisole hydrochloride on the infection day or with 7% levamisole hydrochloride one day before the infect ion. The worm reduction rates were all 100% when the mice were embrocated with 2 %, 3% or 5% alkali levamisole one day before the infection. Conc lusions Levamisole liniments can prevent from S . japonicum cercaria infection, and alkali levamisole is better th an levamisole hydrochloride. When levamisole is given orally, no effect was show n.

Objective:To investigate the relation of antiradiation effect of LJP and lymphocyte apoptosis. Methods:36 Wistar rats were randomly divided into 6 groups (n=6): control, model,and LJP given i.g.at 4 doses(100,200,300,400 mg/ kg bw) for 10d before whole-body irradiation with 9.0 Gy Co?-ray. 18h later,the effects of LJP on the indices of immune function of the irradiated rats 60 were measured. TUNEL and flow cytometry were used to study the effects of LJP on splenic lymphocyte apoptosis and immunohistochemical technique was used to detect the expression of Bcl-2 and the Bax protein. Results:LJP significantly modulated immune function in irradiated rats. The apoptosis ratio of splenic lymphocyte of the model group was higher than those of other groups. LJP could markedly inhibit the effects of irradiation on apoptosis and increase the ratio of bcl-2/bax protein in dose-effect manner. Conclusion:LJP could inhibit splenic lymphocyte apoptosis induced by irradiation, and its mechanism is associated with regulating the expression of bcl-2 and bax protein of splenic lymphocyte. Key word:laminaria japonica polysaccharides; irradiation; lymphocyte; apoptosis apoptosis-related genes

Aim To explore the effects of heat stress on TNF-?-induced fever and the content of cAMP in rat hypothalamus. Methods ①We examined the peak time of HSP70 expression in hypothalamus after heat stress; ②We studied the change of TNF-?-induced fever and the content of cAMP in hypothalamus after heat stress. Result The maximum expression of HSP70 in hypothalamus was attained at 12 h after heat stress. Heat stress limited TNF-?-induced fever and decreased the content of cAMP in hypothalamus. Conclusion Heat stress can inhibit TNF-?-induced fever in rats, and this effect may be related with the inhibition of cAMP synthesis induced by high expression HSP70 in hypothalamus.
