This study is based on the application of the medical simulator and the multimedia technology to the medical English teaching for overseas students during their clinical practice in surgical department.It shows that this teaching model is effective by delivering a good studying surroundings and various language carriers.

At present,nutrition therapy plays a very important role in critically ill children,which can impact on the development and outcome of the disease by the process of metabolism and immunity.Immune-modulating nutrients,such as glutamine,which is a current hot topic,but now there is a little research in it in critically ill children,and this paper summarizes the approach,the dose and the efficacy of glutamine in critically ill children,aiming to offer reference in clinics.

0.05).Conclusion The 4-combine radical treatment to Hp infection can reduce the concentration of ammonia in gastric juice and blood ammonia obviously in patients with liver cirrhosis,whose Child-Pugh grade are A and B,and the treatment is effective in preventing heptic encephalopathy.

Objective To study the levels of interleukin(IL)-2 ,interferon-γ(IFN-γ) and IL-10 in peripheral blood and the effec-tive concentration of lactate dehydrogenase(LDH) in serum of patients with acute leukemia .Methods 65 patients with acute leuke-mia were divided into non-remission group(n=35) and remission group(n=30) .50 healthy volunteers were used as control group . The levels of IL-2 ,IFN-γ ,IL-10 in peripheral blood were measured by enzyme linked immunosorbent assay(ELISA) .The effective concentration of LDH was measured by automatic biochemical analyzer .Results The levels of IL-2 ,IFN-γin non-remission group were significantly decreased compared with control group and remission group(P<0 .05) ,but the level of IL-10 in non-remission group was significantly increased compared with control group and remission group(P<0 .05) .The effective concentration of LDH in non-remission group was significantly higher than that in control group or remission group(P<0 .05) .Conclusion The levels of IL-2 ,IFN-γand IL-10 in peripheral blood and the effective concentration of LDH in serum of patients with acute leukemia have changed .Clinical detection of IL-2 ,IFN-γ,IL-10 and LDH may contribute to the early diagnosis of patients with acute leukemia .

To provide suggestions for perfecting essential drug centralized bidding and purchasing system. Methods:Using literature method to analyze comparatively essential drug bidding purchasing implement plans of 30 provinces in China. Results:Bidding mode in most provinces was double envelope system. Most evaluation methods did not distinguish the quality level, while there were great differences among provincial evaluation standard and scores of economic, technical and business bidding. Conclusion: To explore scientific and reasonable evaluation standard, it needs to establish an authoritative evaluation system for reference, choose the objective index as far as possible and properly increase the amount of bidding manufacturer.

Objective To investigate the optimal time points for transplantation with in vitro cultured dopaminergic neurons as a potential treatment of Parkinson’s disease. Methods After the ventral mesencephalic precursors from E11 rat embryos were expanded for 7 days in vitro, they were harvested respectively from day 0 to day 7 in the period of induced differentiation. Then the cells were seeded again and cultured for another 7 days. The final survival of dopaminergic neurons determined the optimal time points for moving cells in vitro and, possibly, for transplantation in vivo. Result The survival rate of dopaminergic neurons moved on day 0 and day 1 in the period of induced differentiation was significantly higher than that at other time points. Conclusion The optimal time points for transplantation are found possibly to be day 0 and day 1 in the period of differentiation after the expansion of ventral mesencephalic precursors from E11 rat embryos.

To investigate the chemical constituents in the stems of Chirita longgangensis var. hongyao, methanol extract of the stems was subjected to column chromatography with various chromatographic techniques. One new beta-naphthalenecarboxylic acid biglycoside, 1, 4-dihydroxy-2-naphthalenecarboxylic acid methyl ester-4-O-alpha-L-rhamnopyranosyl-(1-->6)-beta-D-glucopyranoside (1) was isolated, along with two known compounds: isotaxiresinol 4-O-methyl ether (2) and (R)-7-hydroxy-alpha-dunnione (3). Compound 2 was first obtained from Chirita genus and compound 3 was isolated from this plant for the first time. All structures were elucidated on the basis of spectral and chemical evidence, and the NMR spectroscopic data of compound 2 was published for the first time.

Objective To observe the clinical change of cytokines expression in peripheral blood in patients with allergic asthma and its significance .Methods Forty patients with allergic asthma and thirty healthy controls were enrolled .The concentrations of IL‐17 ,IL‐22 and IL‐10 in peripheral blood were measured by ELISA ;the serum IgE levels were measured by electrochemical lumi‐nescence method ;The eosinophil proportion was detected by blood cell analyzer ;the IL‐17 ,IL‐22 ,IL‐10 and the severity of asthma were conducted Pearson correlation analysis .Results The level of serum IgE and eosinophil proportion was significantly higher in patients with allergic asthma compared with the controls (P<0 .05);compared with the control group ,the concentration of IL‐17 and IL‐22 in peripheral blood of patients with allergic asthma were increased ,but the expression of IL‐10 were decreased (P<0 .05);the level of IL‐17 and IL‐22 were positively correlated with severity of allergic asthma (P<0 .01) ,but the level of IL‐10 was negatively correlated with severity of allergic asthma (P<0 .05) .Conclusion The expression of IL‐17 ,IL‐22 and IL‐10 play an im‐portant role in the pathogenetic mechanism of allergic asthma ,and a dynamic monitoring could be helpful for the diagnoses and treatment of allergic asthma .
