Chinese Traditional and Herbal Drugs 1994;0(11):-
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.

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 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.

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.
