Objective To investigate the association between nonalcoholic fatty liver disease (NAFLD) and metabolism or carotid intima-media thickness (CIMT) in Type 2 diabetic(T2DM). Methods According to the liver B-ultrasonography, a total of 321 T2DM patients were divided into two groups, with or without NAFLD. Metabolic indexes such as BMI, BP, blood glucose, blood lipid, uric acid ( UA ), insulin, C-peptipe,insulin resistance index(HOMA-IR) between the two groups were compared, and the relationships between alanine aminotransferase (ALT) and the above indexes were analyzed. Furthermore,the CIMT of the two groups were compared, and the relationships between NAFLD, ALT and CIMT were investigated by correlation and regression analysis. Results Compared with the group without NAFLD, the patients with NAFLD had higher level of BMI, triglyceride ( TG ), UA, fasting blood glucose ( FBG ), fasting insulin ( FIns ), fasting C peptide (FCP) ,HOMA-IR,and lower level of high density lipoprotein ( HDL-C ) significantly; BMI ( OR = 1.25, P ＜0. 001 ), TG ( OR = 1.74, P = 0. 008 ) and HOMA-IR ( OR = 2. 33, P = 0.010) were independent risk factors of NAFLD while H DL-C was independent protective factor; ALT was positively correlated with BMI (r = 0. 255, P ＜0. 001 ) ,TG(r =0. 156,P ＜0. 018) ,UA(r =0. 239,P ＜0. 001 ) ,FIns(r =0. 213,P =0. 001) ,FCP(r =0. 199,P ＜0. 003), HOMA-IR ( r = 0. 247, P ＜ 0. 001 ) and negatively correlated with HDL-C ( r = - 0. 199, P =0. 002) ,and BMI (β =0. 456,P =0. 048) ,UA (β =0. 021 ,P =0. 025) and HOMA-IR(β =3.634 ,P =0. 004)were independent associated facrors. The difference of CIMT between the two groups didn't reach statistical significance, while mutiple regression analysis revealed that ALT was independently associated with CIMT(β =0. 002,P = 0. 013). Conclusion T2DM patients with NAFLD show more serious disorder of metabolism and insulin resistance. ALT is an independent risk factor of CIMT in T2DM patients.

Objective To test intraoperative radiotherapy with mobile photon beam using the INTRABEAM system ( Germany) , and to analyze the dosimetric characteristics of low?energy photon beam using X?ray source and spherical applicators and explore its potential limitations in clinical application. Methods A special water phantom, a parallel?plate ionization chamber, and an electrometer were used to measure the depth dose rates and isotropy of dose distribution in x/y plane of X?ray source and different spherical applicators in the INTRABEAM system. Those data were then compared with the system data. Results For the X?ray source, the deviation of observed depth dose rate and isotropy in the x/y plane from the system data were-2.16%± 1. 36% and-1.9%~ 2. 1%, respectively. For applicators with different diameters, the deviation of observed depth dose rate, transfer coefficient, and isotropy in x/y plane from the system data were-10.0%~2. 3%,-8.9%~4. 2%, and-1.6%~2. 6%, respectively. Surface dose rate and dose gradient became larger with the decrease in the diameter of the spherical applicator. The measurement of depth dose rate and isotropy of X?ray source and spherical applicators showed good repeatability. The influencing factors for measurement accuracy included the positioning error of ionization chamber, energy response, noise current, and correction factor f ’ ( R ) . Conclusions This study reveals the dosimetric characteristics of the INTRABEAM system, verifies the accuracy of the system data, and obtains the data for clinical application and routine quality assurance. However, large dose gradient and small therapeutic range may limit its wide clinical application.

ObjectiveTo explore the characteristics and risk factors of suicidal ideation among community subjects in Xiamen city and to provide appropriate suicide intervention strategies.MethodsUsing multi-stage stratified cluster sampling,12071 subjects aged 18 years and older were identified in Xiamen City.Their suicidal ideation was recorded with the investigation list made by Beijing Huilongguan Hospital Beijing Suicide Research and Prevention Center.Psychiatrists determined their diagnosis with Diagnostic and Statistical Manual of Mental Disorder 4th edition (DSM-Ⅳ).ResultsA total of 10757 subjects completed the survey,the completion was 89.1％.The life-time prevalence of suicidal ideation was 2.48％ (95％CI:2.19％ ～ 2.77％ ),the prevalence was higher in female(3.00％ ) than male( 1.88％ ) (RR =1.60,95％CI:1.24 ～2.06).Analysis of risk factors by single logistic regression showed that the suicidal ideation of persons were mostly in female,44 years and older group,in rural,not-being married,no medical insurance,poor mental or physical health in last month,being in hospital due to the mental problems,low quality of life,living alone,having blood relatives or acquaintance with suicidal behavior.While the risk factors by muhivariate logistic regression were ranked as follows:having acquaintance with suicidal behavior (OR =3.66,95％CI:2.44 ～5.50),being in hospital because of mental problems (OR =3.30,95％CI:1.08 ～10.09),poor mental health in last month(OR =3.17,95％CI:2.37 ～4.24),any blood relatives having suicidal behavior (OR =2.91,95％CI:1.61 ～ 5.25 ),low of quality of life (OR =2.21,95％CI:1.50 ～ 3.26 ),not-being married (OR =1.73,95％CI:1.28 ～ 2.32),living alone (OR =1.65,95％CI:1.18 ～ 2.32),being female (OR=1.57,95％CI:1.21 ～ 2.05).The prevalence of mental disorders in suicidal ideation was 46.4％.ConclusionThe prevalence of suicidal ideation is significantly higher in female residents than in male.Having acquaintance with suicidal behavior,being in hospital due to the mental problems as well as poor mental health in last month are the main risk factors of suicidal ideation.
