1.Insulin sensitizers in treatment of nonalcoholic fatty liver disease.
Chinese Journal of Practical Internal Medicine 2001;0(05):-
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 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.

ObjectiveTo explore the best measurement of waist circumference related with intra-abdominal fat volume evaluated by CT scan.MethodsHeight,weight,and hip circumference were measured among 147 subjects aged over 18 years old.Waist circumference was measured at 3 different levels:the upper brim of the iliac crest ( WC1 ),the midpoint between costal brim and iliac crest ( WC2 ),and the umbilicus ( WC3 ).The intra-abdominal fat volume was evaluated by CT scan.ResultsIntra-abdominal fat volume was significantly higher in men than in women [ ( 1 236.0±608.4 vs 931.0±665.0)cm3,P<0.01 ].Correlation analysis showed that WC1 ( r =0.634),WC2( r=0.677),and WC3 (r =0.712)were positively correlated with intra-abdominal fat volume ( all P<0.01 ).Partial correlation analysis adjusted by gender,weight,or body mass index showed that the correlation of intra-abdominal fat volume with WC3 ( r were 0.488 and 0.432) was better than that with WC1( r were 0.347 and 0.293 ) and WC2 ( r were 0.424 and 0.365 ).Multiple linear stepwise regression analysis demonstrated that WC2 and WC3 were independently associated with intra-abdominal fat volume and WC3 was the strongest impact factor (β =0.270,R2c =0.504,P<0.01 ).ConclusionsWaist circumference is a simple anthropometric measurement parameter reflecting the degree of intraabdominal fat accumulation.All three different measurements of waist circumference may reflect intra-abdominal fat volume,while waist circumference at umbilical level is the best among them.

Radiotherapy not only acts as an important local treatment of cancer, but also plays a key role in regulation of immune function. Radiotherapy regulates anti?tumor immune responses by promoting the generation of neoantigens, regulating the release of cytokine, and enhancing the sensitivity of tumor to cell?mediated immunity. Recently, several studies and clinical practice reported the abscopal effect in some patients undergoing radiotherapy combined with immunotherapy, which showed partial or complete response of metastases outside the irradiation field, suggesting the combination therapy as a promising strategy. However, further studies are needed for the understanding of the mechanism and influencing factors for immunity such as radiation dose and fractionation scheme. This paper reviews the research advances in the mechanism of radiotherapy?immunotherapy interaction and the combination therapy for cancer.

Malignancies threaten human health seriously.Recently studies show that intercellular signal transduction influences the biological characteristics of tumor cells.It has closely relationship with tumor growth and metastasis.Insulin-like growth factor ( IGFs ) signal transduction system is a potential mitogen that distributed in the body′s tissues, organs and blood.Researches show that the abnormal expression of IGFs exists in many tissues, such as breast cancer, colorectal cancer, gastric carcinoma, lung carcinoma, pancreatic cancer and so on, which may play an important role in occurrence and metastasis as a novel tumor marker.
