AIM: To explore the effect of Danshen on warfarin via detecting the patients with atrial fibrillation. METHODS: With the help of detecting prothrombin time(PT) and international normalized ratio(INR) of the patients who took warfarin only or both Danshen and warfarin,we compared the PT and INR of each group. RESULTS: At steady-state levels of warfarin,Danshen prolonged the PT(P

Objective To study the connection between vascular endothelial growth factor(VEGF) and pool prognosis in nephroblastoma.Methods Serum VEGF was measured with immuneohistochemical(ELISA) methods in 35 children of nephroblastoma at preope-ration,1 week,2 weeks after surgery respectively. Simple visiting happened after surgery 4,8,16,32 weeks.The countrol group was 35 healthy children. Result Before surgery,the median VEGF in the children was (89.47?22.45) ?g/L.After surgery 1 week,2 weeks,levels in the children fell significantly to (2.75?0.31) ?g/L,(1.52?0.18) ?g/L.There was a significant difference compared with preoperation ( t =4.125 P

Aim To investigate the mechanism of dia-betes changing the hepatic CYP1 A2 through in vitro cell culture study.Methods The function of CYP1 A2 in HepG2 and Fa2N-4 cells were evaluated by determi-ning the level of phenacetin metabolism,and the mR-NA expression of CYP1 A2 in cells was detected by real time PCR.HepG2 cells were co-cultured with serum of diabetic rats(type 1 and type 2)and normal rats,then the CYP1 A2 function in cells were evaluated.Then, the HepG2 and Fa2N-4 cells were co-cultured with a series of concentrations of saturated (including palmitic acid and stearic acid)and unsaturated fatty acids(in-cluding oleic acid and linoleic acid)for 48 h,and the function and expression of CYP1 A2 in the cells were compared.Results It was found that the activities of CYP1 A2 were higher in cells incubated with diabetic serum of both type.All high concentration of fatty acids could increase the function and expression of CYP1 A2 in both HepG2 and Fa2N-4 cells.Conclusion It is speculated that the abnormal level of fatty acids under diabetic state might be part of the reasons why diabetes change the hepatic CYP1 A2,which provides the basis for future study.

Objective To investigate effect of artesunate on expressions of Toll-like receotor-4 (TLR4) and interleu?kin-8 (IL-8) in renal tissue of diabetic nephropathy rats. Methods Male SD rats of over 200 g in body weight (n=45) were injected with low dosage streptozotocin and fed with high fat and sucrose diets to establish diabetes nephropathy (DN) model. Among all rats of successful model, thirty-two were randomly selected and divided into four groups (n=8 in each group), Mod?el group (Group B), Artesunate at high dose treatment group [30 mg/(kg · d)] (Group C), Artesunate at low dose treatment group [10 mg/(kg·d)] (Group D), Enalapril treatment group [10 mg/(kg·d)] (Group E). Another eight rats without STZ injec?tion whose body weight is under 200 g were assigned as Normal group (Group A). Then, rats in Group A and B were given the same volume of normal saline [10 mg/(kg·d)] while rats in Group C, D and E were given 30 mg/(kg·d) Artesunate, 10 mg/(kg·d) Artesunate and 10 mg/(kg · d) Enalapril respectively intragastrically for consecutive 12 weeks. Fasting blood glucose, body weight, kidney index, 24-hours proteinuria, serum creatinine (Cr) and blood urea nitrogen (BUN) were measured. Expression level of TLR4 in renal tissue of rats were examined by Western blot;ELISA was used to quantify the concentration of IL-8 in serum and renal tissue of rats. Results Compared with rats in Group A, the levels of Fasting blood glucose, kidney index , 24-hours proteinuria, Cr and BUN as well as the level of TLR4 in kidney, levels of IL-8 in serum and kidney all significant?ly increased in rats in Group B, C, D and E(P<0.05). On the other hand, body weight were decreased in rats of Group B, C, D and E compared to rats in Group A(P<0.05). The level of TLR4 in kidney, levels of IL-8 in serum and kidney, 24-hours proteinuria, Cr and BUN in rats of Group C, D and E were significantly lower than those in rats of Group B(P<0.05). Furthermore, compared with rats in Group D, the levels of TLR4 in kidney, IL-8 in serum and kidney, 24-hours proteinuria, Cr and BUN were decreased in rats in Group C and E(P<0.05). Pearson correlation analysis showed that the expression lev?el of TLR4 positively correlated with IL-8 level in serum (r=0.969, P<0.05), IL-8 level in kidney (r=0.972, P<0.05), 24-hours proteinuria(r=0.965, P<0.05), Cr(r=0.944, P<0.05)and BUN(r=0.903, P<0.05). IL-8 level in kidney positively correlated with 24-hours proteinuria(r=0.962, P<0.05), Cr(r=0.929, P<0.05)and BUN(r=0.940, P<0.05). Conclu?sion Artesunate decreases expression of TLR4 and IL-8, reduce 24-hours proteinuria, inhibits the inflammation of the DN,relives the pathological lesions of nephron rats with diabetic nephropathy.

Because of the population aging,the increase of the stroke patients and the need for rehabilitation,the treatment only in the rehabilitation department of the hospital is far from the satisfaction of people's demands of the service of rehabilitation.It is important to extend the community-based rehabilitation.Compared with the rehabilitation in hospitals,it is more economy,efficiency and convenience for stroke patients in community-based rehabilitation services,and further improve the rehabilitation effect of stroke patients.

Objective: To investigate the anticancer effects of the Zaoxiu Compound Decoction (ZCD) on H22 mice with Heps and the influence on the construction of H22 cells. Methods: With in vivo techniques, the antineoplastic drugs were given to hepatoma H22 model mice which were randomly divided into negative control (physiological saline), positive control (cyclophosphamide), high- and low-dose ZCD groups. After 10-d administration, the pathological examinations of tumor tissue, livers, and kidneys in mice were carried out and the inhibitory rate on tumor was calculated. Results: The high- and low-dose ZCD had obvious inhibition on H22 cells. The pathological observation showed that high- and low-dose ZCD had a strong inhibitory effect on H22 cells as well as positive control, with few toxic effects to the livers and kidneys in mice. Conclusion: ZCD has the anticancer effect and has no obvious toxic effects on the model mice. © 2013 Tianjin Press of Chinese Herbal Medicines.

Education of history of science may not only cultivate spirit of science,critical spirit,methods of thought,innovative spirit and sense of responsibility,compassion and enterprise,but also provide cognition on illogical methods of thought and taste of aesthetic philosophy.Education of history of science in Medical academy is an important channel to advance medicos' comprehen- sive quality.Enhancing cognition and developing multifarious educating activities of history of science is an important tendency in reformation of medical education.
