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:[WT5BZ] The effects of exogenous vitamin C (VC) and glutathione (GSH) on ultraweak spontaneous luminescence of culturing pulmonary alveolus macrophages from rabbits were studiesd. [WT5FZ]Methods:[WT5BZ] In a special thermostat, which was passed through by airs with various concentrations of oxygen, the alveolar macrophages (AMs) were cultured in DMEM medium with VC or GSH, and the spontaneous luminescence of culturing AMs was examined by a luminometer. [WT5FZ]Results:[WT5BZ] when VC in medium was over 0.3 mmol/L, it could significantly enhance the oxidative luminescence of cells exposed to O 2 and cell death was resulted. However, when the cells were exposed to air without O 2 there was no significant effect. On the contrary,the lower concentration of VC (0.03 mmol/L) as well as GSH could reduce the spontaneous luminescence of cells exposed to a high concentration (99.1%) of O 2 in air. [WT5FZ]Conclusion:[WT5BZ] The results show that the spontaneous oxidation of culturing cells is an important reason for the ultraweak luminescence. High concentration of VC can promote cellular oxidative damage in vitro, but the exogenous GSH has a protective effect against oxidization in culturing cells.

Objective To understand the occupational exposure among medical laboratorians in a hospital,and put forward prevention and control measures.Methods Occupational exposure among medical laboratorians in the department of laboratory medicine of a hospital from January 2011 to December 2014 were analyzed statistically.Results A total of 72 cases of occupational exposure occurred among 217 laboratorians during 4 years,occupational exposure rate was 33.18％,the occupational exposure rate in interns was 46.23％,and in laboratorians with working seniority＜ 1 years was 49.56％.Occupational exposure mainly occurred in outpatient blood collection room(accounting for 38.89 ％),the main occupational exposure types were injuries by blood collection needles,skin contaminated by blood and body fluid(76.39 ％).Occupational exposure rates in medical laboratorians in this hospital during 2011-2014 were 53.66％(22/41),41.67％(20/48),26.23％(16/61),and 20.90％(14/67),respectively,which presented a declining tendency(x2 =12.286,P＜0.01).After occupational exposure,only 23 cases were reported according to the requirements of infection management department,the missing report rate was 68.06％ (49/72),correct handling rate was 80.56％ (58/72).Conclusion Laboratorians should strengthen education and training of healthcare-associated infection management,improve safety and prevention consciousness,standardize handling process,improve consciousness of reporting,so as to reduce the occurrence of occupational exposure and post exposure infection.
