OBJECTIVE: To provide references for the improvement of categorized management of drugs in China. METHODS: The problems in China's categorized management of drugs were analyzed by drawing a comparison between China and USA in the categorized management of drugs. RESULT & CONCLUSION: China should draw on useful experiences from the developed countries to improve the categorized management of drugs from multi-aspects.

Objective To study the effects of atorvastatin on expression of lysyl oxidase(LOX) in myocardial tissue of rats with diabetic cardiomyopathy (DCM) and its mechanism.Methods Thirty DCM SD rats were randomly divided into 3 groups:DCM group,treatment group (atorvastain 2 mg · kg-1 · d-1 by gastric gavage) and β-aminopropionitrile group(β-aminopropionitrile 80 mg · kg-1 · d-1 by gastric gavage),10 cases in each group.Other 10 SD rats were selected as the control group.At the end of week 8,the rats were killed for extracting the myocardial tissue RNA and protein.Expression levels of LOX,MMP-2 and NF-κB mRNAs and proteins in myocardial tissue of DCM rats were measured by RT-PCR and Western blot.Results The expression levels of LOX,MMP-2 and NF-κB mRNAs and proteins in the DCM group were significantly higher than those in the control group (P＜0.01),and compared with the DCM group,the expression of BAPN LOX,MMP-2 and NF-κB mRNA and proteins in the treatment group were significantly deceased (P＜0.01).Conclusion Atorvastatin can reverse the expression of LOX in myocardial tissue of DCM rat,and then may regulate the expression of MMP-2 and NF-κB.

Objective To explore the relation between the infection of Helicobacter pylori (H .pylori)and colorectal tumor.Methods From January 2012 to January 2013,the medical data of 152 patients with colorectal tumor were collected.According to the findings of colonoscopy examination, the patients were divided into the colorectal adenoma group (84 cases)and the colorectal carcinoma group (68 cases).A total of 88 healthy individuals were also enrolled as control.The differences of H .pylori infection were compared among the colorectal adenoma group,the colorectal carcinoma group and the healthy control group.The distribution of H .pylori infection in different age,gender and nation was analyzed in colorectal tumor group.According to the location,maximum diameter,number,type of pedicle and pathological type of adenoma,the colorectal adenoma group was divided into subgroups and the condition of H .pylori infection was compared among the subgroups.Chi-square test was used in the statistical analysis.Results The positive rates of H .pylori infection of colorectal adenoma group, colorectal carcinoma group and healthy control group were 70.2% (59/84),72.1 % (49/68)and 53.4%(47/88),respectively,where the former two groups were both higher than that of the healthy control group,and the differences were statistically significant (χ2 =5 .147 and 5 .637,both P <0.05).Regarding the H .pylori infection,there was no difference in age,gender and ethnicity among 152 patients with colorectal tumor (all P > 0.05 ).Among 84 patients with colorectal adenoma,there was no statistical difference in the positive rate of H .pylori infection in different location,maximum diameter,number, type of pedicle and pathological type of adenoma (all P > 0.05).Conclusion H .pylori may have promoting effects on the genesis and development of colorectal tumor.

Objective To compare the differences between external standard method and relative correction factor method for determination of the flavonoids from Sorbus tianschanica Rupr.Methods Using HPLC external standard method for determination of hyperoside,rutin,isoquercitrin,quercetin-3-O-(6″-O-malonyl)-β-D-glucoside,astragalin and Kaempferol-3-O-(6″-O-malonyl)-β-D-glucopyranoside in Sorbus tianschanica Rupr.,HPLC relative correction factor method was adopted to establish relative correction factor of the other five flavonoids above with hyperoside as reference.The difference was evaluated by comparing the external standard method with the relative correction factor method.Results There was no significant difference between the T test external standard method and relative correction factor method(P>0.05).Conclusion External standard method and relative correction factor method can be used for determination of the flavonoids from Sorbus tianschanica Rupr.,but in the case of lack of reference substance or mass detection,using the relative correction factor method for determination of rutin,hyperoside isoquercitrin,quercetin-3-O-(6″-O-malonyl)-β-D-glucoside,astragalin and kaempferol-3-O-(6″-O-malonyl)-β-D-glucopyranoside in Sorbus tianschanica Rupr.It was more feasible and it can be used as a new quality evaluation method in determination of flavonoid components from Sorbus tianschanica Rupr.

Objective To study the effects of MT egg-milk powder on the contents of lead,zinc,iron and copper in brain and femur of lead poisoning rats. Methods 30 Wistar rats were divided into three groups(n=10): normal control group, lead poisoning group and lead poisoning rats treated with MT egg-milk powder group. After treated with 0.2% lead acetate daily for three weeks, the rats were fed with 500 g?L~ -1 MT egg-milk powder for three weeks. At the end of the experiment,samples of brain and femur were collected for trace elements detection by atomic absorption spectroscopy. The concentration of hemoglobin was determined by haemiglobincyanide method. Results Compared with the control, the contents of zinc and hemoglobin in brain and femur were significantly decreased (P
