目的分析正清风痛宁(盐酸青藤碱)治疗膝骨性关节炎的临床效果。方法以"正清风痛宁"、"膝关节骨性关节炎"、"膝骨性关节炎"、"zhengqingfengtongning"、"Osteoarthritis of the knee"、"knee osteoarthritis"为关键词检索中英文数据库,检索时间是1990年—2014年11月。整理完数据后使用Revman 5.1软件进行Meta分析。结果纳入12个随机对照实验,共930例患者。对于膝骨性关节炎的短期疗效,使用正清风痛宁组要明显优于单独使用西药组(OR=1.93,P<0.000 1);同时,结合亚组分析的数据表明,无论正清风痛宁是单独使用还是联合西药使用,其效果都明显优于单独使用西药组(OR=1.86,P=0.02;OR=1.98,P=0.002);然而对于治疗膝骨关节炎的6个月远期结局使用正清风痛宁组和单独用西药组相比无显著差异(OR=1.64,P=0.10)。结论使用正清风痛宁医治膝骨性关节炎的短期效果要明显优于单独使用西药。但是对于6个月的远期结局二者的差异并不显著。
Two new photolabile nucleotide analogues with furan-fused deoxyuridine were synthesized through Sonogashira coupling.Their enzymatic incorporation into DNA was evaluated with two DNA polymerases(Taq and Deep vent exo-)by polymerase chain reaction(PCR).Deep vent exo-recognized both nucleotides as substrates for primer extension,while Taq was much less proficient.Light irradiation of PCR products released the amino and carboxyl moieties of DNA.Further labeling with fluorescein isothiocyanate for a long DNA construct with F-dUnTP incorporation was successfully achieved.
