Objective To establish culture method for Phyllanthus urinaria. Methods To study the possible effective factors of culture condition by comparing with different explants,sucrose,plant growth substance,and its ratio. Results The inductivity of stem was the highest about 55.56%,but callus of leaves could not be induced.6-BA was the most important factor on callus induction,followed by 2,4-D NAA and sucrose. Conclusion The optimal medium to induce and subculture is MS+2,4-D 0.5 mg/L+6-BA 1.0 mg/L+NAA 0.1 mg/L+sucrose 10 g/L.

OBJECTIVE:To probe into the status quo and the trend of the utilization of the oral stasis-eliminating Chinese patent medicine in our hospital in order to provide scientific basis for rational use of this medicine.METHODS:The consumption amount and consumption sum of the oral stasis-eliminating Chinese patent medicine in our hospital during 2006-2008 were reviewed in respect of the DDDs and DDC using DDDs ranking method.RESULTS:During 2006～2008,the consumption amount of the oral stasis-eliminating Chinese patent medicine in our hospital had a steady increase,and the DDDs showed a good synchronism.CONCLUSION:The use of stasis-eliminating Chinese patent medicine is rational in our hospital.

The premembrane and envelope proteins (prM-E),which contains the mainly protective antigen related with virulence and tropism,are the primary structural protein of flavivirus.However,prM-E in ZIKV is rarely understood.We have analyzed the structure and biological effects of prM-E in ZIKV by bionformatics methods.The prM-E proteins virus-like particles of dengue virus was introduced in the present.Then,the prM-E proteins virus like particles of ZIKV was prospected.

Objective To investigate the effects of different doses of ulinastatin on platelet counts and function after normothermic cardiopulmonary bypass (CPB) in rabbits. Methods Fifty lung-ear white rabbits aged 5-6 months weighing 2.3-3.0 kg were randomly assigned to one of 5 groups (n = 10 each) : control group (group C) and4 ulinastatin groups (group U~1, U_2,U_3,U_4). The rabbits received ulinastatin 1×10~4, 3×10~4, 5×10~4 and 10×10~4 U/kg before CPB in group U~1, U_2, U_3 and U_4 respectively while equal volume of normal saline was given instead of ulinastatin in group C. All rabbits underwent CPB for 30 min at perfusion flow of 72-120 ml·kg~(-1) ·min~(-1). The rectal temperature was maintained at 36.5-37.5℃. Hemodynamic parameters were recorded and blood platelet count, platelet adhesion rate and platelet membrane glycopretein Gp Ⅰ b, Gp Ⅱ b, Gp Ⅲ a receptors were determined before CPB (baseline), at termination of CPB and at 1, 2 and 3 h after CPB. Results The platelet counts were significantly decreased after CPB in all 5 groups (P< 0.05), but there was no significant difference among the 5 groups. The platelet adhesion rates were significantly decreased after CPB as compared with the baseline value before CPB in all 5 groups but the platelet adhesion rates were significantly higher after CPB in group U_4 than in group C. The number of molecules of Gp Ⅰ b, Gp Ⅱ b and Gp Ⅲ a receptors was significantly decreased after CPB in all 5 groups. The number of molecules of Gp Ⅰ b, Gp Ⅱ b and Gp Ⅲ a receptors after CPB was significantly higher in group U_2, U_3 and U_4 than in group C, and there was no significant difference between group U_3 and U_4 . ConclusionUlinastatin 3×10~4-5×10~4 U/kg administered before CPB can inhibit breakdown of platelet membrane glycoprotein receptors. Ulinastatin 10×10~4 U/kg can preserve the platelet adhesion function.

OBJECTIVE To make clear the germicidal efficacy of a large-sized pressure-stream disinfector for(bedclothes) used in the hospital.METHODS The carrier-ration sterilization experiment and local disinfection(experiment) were used to test the germicidal efficacy of pressure-stream disinfector for microorganism being on the contaminated bedclothes.RESULTS Operating the disinfector at the 105℃ for 5 minutes,its killing rate of Staphylococcus aureus,Escherichia coli and Candida albicans on bedclothes was 100%,the natural killing rate of(surface) of bedclothes exceeded 99.28%.CONCLUSIONS The pressure-stream disinfection is an excellently(effective),economical and environment protective method,it deserves to be used widely.

Objective To investigate the effects of stimulation of CD40 on the growth,prolifera- lion and apoptosis of gastric cancer cell lines,and the change of gene expression profiles of gastric cancer cell AGS.Methods The growth and proliferation of AGS cells treated with different concentrations of soluble CD40 ligand were measured by MTT in order to choose optimum stimulating concentration of so- luble CD40 ligand.Cell cycle and apoptosis of AGS cells were analyzed by flow cytometry.Gene expres- sion profiles of AGS cells were analyzed by Affymetrix U133A 2.0 after treated with soluble CD40 ligand for 48 h.Results Two?g/ml of.soluble CD40 ligand was the optimum concentration.After being cul- tured with soluble CD40 ligand for 48h,the growth of AGS cell was inhibited and blockade in G1 phase. There were 414 alterative genes found in AGS cells including 209 up-regulated genes and 205 down-regu- lated genes.Forty-five genes varied significantly(P

Objective To assess the effectiveness of supracricoid partial laryngectomy in the treatment of laryngeal cancer. Methods This study infiuded 22 patients operated on from 1993 to 2000 using this surgical procedure. 22 were males with mean age of 63 years (ranging from 43 to 74 years). 21 were glottic cancers (3 T1aNoMo, 4 T1bNoMo, 11 T2NoMo, 3 T3NoMo) and 1 supraglottic cancer (T2N1Mo) according to the 1997 UICC system. Supracrieoid partial laryngectomy was performed, with the epiglottis preserved and reconstructed with cricohyoidoepiglottopexy (CHEP). Results The overall 3-year and S-year survival rates were 88.24％ and 70％, respectively. All patients were decannulated. The average time for decannulation was 25 days (ranging from 14 to 60 days). Speech was good in all cases. Conclusion CHEP not only excises the neoplasms completely and safely but also preserves the laryngeal physiologic function well.
