Nonalcoholic fatty liver disease(NAFLD)has become one of the most common liver diseases in the world.Considering the important role of insulin resistance in its pathogenic mechanisms,insulin sensitizers are becoming the promising pharmacological strategies for NAFLD.We collected and analyzed the relevant articles in recent years and found that pioglitazone,rosiglitazone and metformin could improve liver enzymes and insulin sensitivity of NAFLD.However,only pioglitazine was supported in ameliorating liver histology by envidences from randomized,double-blinded,controlled clinical trials.There were no much obvious adverse effects in NAFLD patients who received insulin senitizers.Small or medium samples and no more than 2 years of treatment course may be the major limitation of current studies.Future information derived from well-designed running trials will be useful in defining the clinical implications of insulin sensitizers in the treatment of NAFLD.

Objective To study the effect of different fraction interval with same total radiation dose on tumor growth delay and survival in C57BL mice implanted with lewis lung cancer,and to determine whether prolonged fraction interval will decrease the tumor response to radiation. Methods Forty-eight mice were implanted with lewis lung cancer in the back legs.When the diameter of transplanted tumor reached 0.8 to 1 cm,the mice were randomized into 6 groups:normal control group,single fraction of 18 Gy group,18 Gy in 2 fractions of 9 Gy at 30 min interval group,18 Gy in 7 fractions of 2.57 Gy at 5 min inter val group,18 Gy in 2 fractions of 9 Gy at 60 min interval group and 18 Gy in 7 fractions of 2.57 Gy at 10 rain interval group.The maximal and minimal diameters of the tumor were measured and record every other day to study the tumor growth tendency,the tumor growth delay and the mice survival time. Results The tumor growth delay of groups at prolonged fraction interval was shorter than the group with single fraction of 18 Gy (P < 0.05).The tumor growth delay of groups at fraction interval of 30 rain was longer than that of groups at interval of 60 rain (P < 0.05).There was no significant difference of the tumor growth delay be tween the groups with same delivery time (P >0.05).The mice survival time of the groups with prolonged fraction interval was shortened when omparing to the group with single fraction of 18 Gy.While the difference was not significant between the groups at fraction interval of 30 min and 60 min. Conclusions The pro longed fraction interval but same total radiation dose shortens the tumor growth delay and survival time in the mice implanted with Lewis lung cancer.The longer fraction interval impairs the tumor control more signifi candy.However the difference of the effect on mice survival time is not significant between the groups at fraction interval of 30 min and 60 min.

Objective To investigate the correlation between microalbuminuria (MAU) and obesity and its indexes, including BMI, waist circumference(WC), and waist-to-hip ratio(WHR) , among partial community population in Beijing. Methods A total of 2080 subjects who took physical examination in Beijing, including 810 men and 1270 women with a mean age of(50. 9 ± 13. 1 )years, were enrolled. The informed consent has been achieved from each patients. BMI and WHR were calculated based on collected data of height, weight, WC, and hipline. Urine albumin-creatinine ratio(ACR) within the range of 30-300mg/g was classified as MAU. The subjects were divided into normal albuminuria ( NAU ) group and MAU group. The correlations between MAU and different obesity indexes including BMI, WC and WHR, were analyzed. Results Among the 2080 subjects, there was a positive correlation between BMI (r = 0. 1276,P＜0.01) and ACR, and WC (r = 0.0840, P ＜0.01) and ACR. WHR and ACR was irrelevant ( P ＞ 0. 05 ). In univariate analysis, there was significant difference in BMI ≥ 28 kg/m2 ( OR = 2. 02 ) and WC ≥85 cm (male) or≥80 cm (female) (OR = 1.69 ) between NAU group and MAU group (P ＜ 0. 05 ).There was no significant difference in BMI 24-＜ 28 kg/m2, and WHR ≥0. 90 (male) or ≥0. 85 (female)between NAU group and MAU group( P≥0. 05 ). Multivariate logistic regression analysis revealed that BMI ( OR = 1.06) was an isolated independent risk factor of MAU from age ( OR = 1.01 ), female ( OR = 1.42),systolic blood pressure (OR=1.01), TC (OR=1.93) and HDL-C (OR=0.54). Conclusions Obesity is an independent risk factor of MAU among partial community population in Beijing. The correlation between different obesity indexes and MAU also differs.

Objective To establish a sensitive and specific liquid chromatography method for the determination of loganin and morroniside in rat serum containing Liuwei Dihuang Formula(LDF).Methods Loganin and morroniside were extracted from the rat serum using SPE column,then separated on a C_(18)column.A HPLC method for determining serum concentration of mor- roniside and loganin in rats before and after administration LDF was established.Results A good linear calibration curve of lo- ganin and morroniside was obtained.The recovery of the method was in the range of 95 %～105 %.The extracted recovery was more than 75 % ,and within-day and intra-day precisions were less than 12 %.Conclusion This method is sensitive, simple and rapid for monitoring of drug level in the study on pharmacokinetics and different combination of LDF.

Background and purpose:Solitary plasmacytoma of bone(SBP) is a rare disease,reports releveant to this disease are rarely seen. The purpose of this study was to investigate the relation between the clinical features and the prognosis of solitary plasmacytoma of bone. Methods:We reviewed the data of 12 patients diagnosed with solitary plasmacytoma of bone from 1998 to 2007 in Peking University third hospital,the clinical features,treatment and prognosis of the patients were analyzed retrospectively. Results:The age ranged from 37-71 years(mean 49.6 years) ,the male/female ratio was 3 to 1. Immunophenotype analysis showed that 11(91.6%) cases were positive for CD79a,10(83.3%) positive forVS38C,and all negative for CD20. With 12 to 87 months follow-up(average 40?22 months) ,three cases(33%) developed to multiple myeloma,two of them died from infection,the median survival time was 73 months,the 3 year and 5 year survival rate were 90 percent and 75 percent respectively. Conclusion:Middle and old male are more likely to develop SP. The prognosis is good,but some of them can progress to multiple myeloma.

Objective To investigate the correlation between methylation status and death-associated protein kinase 1 (DAPK1) in SiHa and Hela cell line of cervical carcinoma and intervention of DNA methyltransferase inhibitor 5-azacytidine on the expression of DAPK1 and the proliferation of the cells. Methods DAPK1 methylation status was analyzed using methylation-specific PCR methods. The expression of mRNA and protein of DAPK1 were analyzed by RT-PCR and SABC methods after the treatment with 5-azacytidine. MTT assay was used to observe the changes of proliferation activity of the cells after 5-azacytidine treatment. Results DAPK1 genes were methylated and did not express in SiHa cells in the cervical carcinoma. Its expression could be restored by 5-azacytidine. MTT assay showed 5-azacytidine could weaken the proliferation of cancerous cells. Conclusion DAPK1 methylation plays an important role in the carcinogenesis of cervical cells and can reexpress after the treatment with 5-azacytidine which also restored its inhibitory function on carcinoma.
