Objective To summarize the published studies of diabetic cerebral infarction treated by integration of traditional and western medicine (ITWM) or pure western medicine and compare their clinical curative effects. Method The clinical study of ITWM for diabetic cerebral infarction were collected and seleted according to the standard. The effect of ITWM and only western medicine was compared, and Meta-analysis was made. Result 59 studies were included to analysis neurological deficit and the total efficiency. Meta-analysis revealed that the improvement of ITWM is better than pure western medicine treatment. Conclusion The existed limited evidences suggest that ITWM treatment of diabetic cerebral infarction can significantly improve neurological deficit and curative effect. More high-quality randomized, double-blind, placebo-controlled trials are needed to confirm the efficacy and safety of ITWM treatment of diabetic cerebral infarction.

Objective To establish a system in which mouse embryonic stem cells (mESCs) differentiate into insulin-secreting cells in vitro. Methods mESCs were cultured to form embryoid bodies(EBs). EBs were cultured in serum-free medium to obtain nestin-positive cells. The selected nestin-positive cells were expanded,then added nicotinamide into the medium to induce the differentiation of nestin-positive cells. Immunochemistry staining and flow cytometry analysis were made on 15th day after induction.Results Flow cytometry analysis revealed that the percentage of nestin-positive cells were different from EBs. The percentage of nestin-positive cells from EBs were higher than those of other diameters. Nestin-positive cells induced by nicotinamide formed islet-like cell clusters. Percentage of insulin-positive cell induced by 10 mmol/L nicotinamide was higher than those induced by 0 mmol/L or 5 mmol/L nicotinamide(P

Objective:To investigate the influence of combined application of histone deacetylase inhibitor(HDACi)MS-275 and 5-FU on the apoptosis and cycle arrest on human hepatoma cell line HepG2 and unclose the related mechanism.Methods:Divided all the cells into 4 groups:control group,MS-275 group,5-FU group and drug combination group.Flow cytometry(FCM)was used to examine the effects of 5-FU with MS-275 on the apoptosis and cell cycle of HepG2 cells.Bcl-2,Bax,CyclinD1 and P21 protein were determined by Western blot assay.Results:5-FU and MS-275 combination could inhibit HepG2 cell growth through G0-G1 arrest,and induce apoptosis,both time and dose dependently.The combination of two agents increased P21 protein levels and decreased Bcl-2,CyclinD1 protein levels.The levels of Bax protein were not changed.Conclusion:The combination of 5-FU and MS-275 can induce apoptosis and cell cycle arrest,the effect might be associated with down-regulating expression of Cyclin D1 and Bcl-2 protein and upregulating the expression of P21 protein.

Objectives To investigate the expression of pax-6 in retina of infant monkeys with myopia induced by optical defocus, and to determine the role of pax-6 would play or not in onset and development of myopia and emmetropization. Methods Nine healthy infant rhesus monkeys, aged from 1 to 3 months, were selected and wore spectacle lenses or underwent photorefractive keratectomy (PRK).Transcription polymerase chain reaction method and quantitative analysis were used to determine the expression of pax-6 in the retina with myopia induced by optical defocus in different time, and the result was compared with that in retina without myopia. Results The myopia caused by hyperopic defocus was found. The expression of pax-6 in the retina with myopia induced by optical defocus was significantly higher than that in the retina without myopia(t=3.480,P=0.004). Conclusions The expression of pax-6 is enhanced by hyperopic defocus in the infant monkey retina, which suggests that pax-6 may be involved in vision-dependent eye growth and emmetropization.

Epidemiological, clinical, laboratory and treatment data, as well as outcomes of 66patients diagnosed as brucellosis during 1984 to 2010 in Peking Union Medical College Hospital were retrospectively analyzed. Thirty-four (51.5%) patients had a history of close contact with sheep or cows infected with brucellosis, eight (12. 1% ) had eaten not-fully-boiled or roasted mutton, three (4. 5% ) had drunk or contacted with contaminated milk, and transmission route was unknown in 21 (31.8%). The most common manifestations were fever ( 97.0%, 64/66 ), loss of appetite and fatigue ( 93. 9%, 62/66 ),sweating (47.0%, 31/66), myalgia and arthralgia (54. 5%, 34/66 ), hepatomegaly (27.3%, 18/66),splenomegaly (37.9%, 25/66), increased erythrocyte sedimentation rate (ESR) (62. 1%, 41/66), and elevated C-reactive protein (65.4%, 34/52). Average interval from onset to diagnosis was 19. 2 weeks. All 66 patients were positive in serum agglutination test for BruceUa, and 28 (42. 4% ) positive in blood or bone marrow culture for Brucella. Sixty-five of 66 patients were treated by standard combined treatment with rifampicin, quinolone, minocycline and streptomycin, with all effective, and only four with mild liver damage in treatment who got better after discontinuing medicines and changing treatment regimen.

Objective: To establish an HPLC method for the simultaneous determination of three flavonoids in Tianjihuang gran -ules.Methods:A ZORBAX Eclipse XDB-C18 column was used.The mobile phase was methanol-0.2%phosphoric acid solution (42∶58).The detection wavelength was 350 nm and the flow rate was 1.0 ml· min-1.Results:The linear range of isoquercitrin, quer-citrin and quercetin was 4.572-114.300 μg· ml-1(r=0.999 8), 7.028-175.700 μg· ml-1(r=0.999 8) and 2.195-54.880 μg· ml-1(r=0.999 9), respectively.The average recovery was 98.01%(RSD=1.24%, n=6), 98.14%(RSD=0.98%, n=6) and 97.00%(RSD=1.09%, n=6) , respectively.Conclusion:The method is specific and simple,which can be used for the quality con-trol of Tianjihuang granules.

Aim To investigate the protective effect of ginsenoside Rb1 against apoptosis induced by H_2O_2. Methods H_2O_2 was used to build an oxidative stress-induced injury model in neonatal rat cardiomyocytes. After treated with gensenoside Rb1(20, 40, 80 mg?L -1),the apoptosis rate, the content of malondialdehyde (MDA), and the activity of superoxide dimutase (SOD) of the cardiomyocytes were examined. The intracellular calcium indicated by the fluorescence in cells were measured by the laser confocal microscope. Results Compared with the model group, the apoptosis rate and the content of MDA of the cardiomyocytes decreased greatly (P

Objective:To obtain the normal values of the facial soft tissue measurements of the attractive Uygur females in Xinjiang by photogrammetric analysis,and to study the relationship between the facial feature of attractive Uygur females and the neoclassical canons. Methods:31 attractive Uygur women were selected, standardized and referenced frontal photographs of faces were taken,and 14 standard anthropometric marks were determined,then measurements were performed by photoshopCS software.Results:Intercanthal width was rather smaller than nose width and larger than eye fissure width;nose width occupied more than 1/4 of face width or 2/3 of mouth width.The chin occupied 2/3 of the entire mandibular height.There was positive correlation among many horizontal and vertical facial soft tissue measurements.Conclusion:The facial features of the attractive Uygur females in Xinjiang fit the classical facial canons to some extent. There is pertinence in attractive facial form and features.
