Objective TO study the effect of trimetazidine on patients with unstable angina pectoris. Methods The pa-tients with unstable anglna pectoris with routine treatment were divided randomly into trimetazidine group(T) and nitro-glycerin group(N). They were given such treatment two weeks. Results There is decreased incidence of angina pectorisand less amount of nitroglycerin consumption in both groups. compared with before. There was no significant difference be-tween the two groups. Conclusion There are no signficantly. Trimetazidine has a definite effect in treating unstable angi-na pectoris,and it is similar to nitroglycerin in effects.

Objective To investigate the molecular epidemiology of GJB2 mutations as a causative effect of prelingual deafness in northwestern China. Methods The medical history of 274 deaf-mute students was collected. Blood samples were obtained from them with informed consent. GJB2 gene sequences of genomic DNAs were amplified by polymerase chain reaction (PCR) with a pair of primers, and bidirectional sequencing of PCR products was performed and analyzed with DNAStar Software. Results A total number of 274 deaf-mute students were diagnosed as non-syndromic hearing impairment, and profound prelingual deafness. Two kinds of polymorphism, seven pathologic mutations and one novel mutation were revealed in the GJB2 screenings of them, and 79G→A and 341A→G were polymorphism with high frequency. Conclusion GJB2 gene mutation is the causative gene in the prelingual deafness with a high incidence of 10.95% in northwestern China. Based on the investigation, it is clear that screening of GJB2 gene mutation should play a significant role in early diagnosis of deaf-mutism in this region.

OBJECTIVE:To provide reference for reasonable and safe use of drugs in children. METHODS:580 prescription drug instructions of chemical drugs and chemical product for treatment were collected from our hospital. Children information stated in drug instruction of exclusive drugs for children and special drugs,and in dosage and usage,clinical trial,pharmacokinetics and other items were all analyzed statistically ratio analysis and sequence analysis. RESULTS:The exclusive drugs for children were few,and major dosage form were injection. The instruction of special drugs were lack of children’s information. Usage and dosage based on monotonous evidence. The pharmacokinetic parameters were incomplete,and there were slender amount of data about chil-dren clinical trials. CONCLUSIONS:The drug instruction of drugs for children are looking blue. It is urgent to standard drug in-struction and complete medication information for children,so as to ensure safe and effective of drug use.

Objective To evaluate the efficacy and safety of bicyclol tablet on hepatic lesions caused by Epstein-Barr virus( EBV) infection in children.Methods A single-center controlled retrospective study was conducted in 121 children with hepatic lesions caused by EBV infection for evaluating safety,tolerability, and efficacy of treatment with bicyclol tablets or Glycyrrhizin capsules.Childer n in bicyclol group ( n=63 ) were treatedw ith bicyclol at blets and cotn rol group ( n =58 ) were treated with Glycyrrhizin capsules.The course of the treatment were both 8 weeeks for two groups.The level of the EBV load pretreatment and plas-ma aminotransferase,blood routine,urine routine pretreatment and 1 week,4 weeks and 8 weeks after treat-mentw ere analyzed er trospectively.Rse ults (1) The pal smaA LT level sigin ficantly decreased in theb icy-clol group compared with that in the contro l group(P<0.01), se pecai lly the levle after 8 weeks treatm ent. (2) Bicycol l was more effce tive in the bicyclol group than Glycyrrhizin capslu se in the control group( P<0.01).(3) Both grousp had no significantlya dvesr e events.Conclusion Bicyclol tablet can derc ease plas-ma aminotransferase level,espce ially ALT,inc hildren caused by EBV infection with better efficiency and safety.

98.95%.The results of certified reference materials were consistent with the target value,and average deviation was -0.31%～1.35%.HPLC was served as the independent variable.When ereatinine was 200 ?mol/L,Bias of Beckman LX20 system,Vitros dry chemistry system and enzymatic method were -10%～13%,-13%～14% and -20%～10%,respectively.Bias of enzymatic method results was mostly negative,when creatinine was

To study the effects of Feiyanning Decoction, a compound traditional Chinese herbal medicine, on proliferation of lung adenocarcinoma cell line A549 cells and their production of interleukin-6 (IL-6) and IL-8 induced by tumor necrosis factor-alpha (TNF-alpha).

Objective: To study the effect of arsenic trioxide (As2O3) on human pancreatic cancer cell proliferation and apoptosis (mainly early stage) in vitro. Methods: SW1990 cells line were trea ted with As2O3 at different concentration. Cell proliferation was evaluated by MTT and apoptosis by Annexin-Ⅴ-fluostaining, electron-microscopy, flow cytometry and immunocytochemical staining of Bcl-2 and Bax. Results: As2O3 and cisplatin had the same cytotoxity on SW1990. The cytotoxic effe ct on tumor cell was produced by induction of apoptosis. Twelve hours after cult ure with 10 μg/ml As2O3, much more SW1990 cells went into apoptosis than t he control. The apoptosis rate reached 24% after 48 h with the similar concentra tion of As2O3. Immunohistochemical study revealed that the expression of Bcl -2 was decreased after treated with As2O3. Conclusion: As 2O3 can depress the proliferation of SW1990 in vitro, mainly through the i nduction of apoptosis, and it is a potential agent for pancreatic cancer chemoth erapy.
