Nonalcoholic fatty liver disease (NAFLD) is associated with obesity, type 2 diabetes,dyslipidemia, hypertension, and metabolic syndrome.It likely represents hepatic manifestation of metabolic syndrome. The prevalence of NAFLD has been estimated to be 20％-30％ in the general population. However, it is much higher in type 2 diabetic patients. Several epidemiological studies indicate that NAFLD is linked to an increased risk of cardiovascular disease( CVD), which is independent of underlying cardiometabolic risk factors. This suggests that NAFLD may also be actively involved in the pathogenesis. The possible molecular mediators linking NAFLD and atherosclerosis(AS) include the release of pro-atherogenic factors by oxidative stress and inflammation as well as atherogenic dyslipidemia, abnormal adipose factors, and insulin resistance, finally aggravating progression of CVD. In this article, the relationship and possible mechanisms between NAFLD and AS are reviewed.

The paper introduced the recent development of optical tweezers array.The particle manipulation system could be set up based on several methods,such as acousto-optics deflectors(AOD),diffractive optical elements(DOE),spatial light modulators(SLM),interference technique,vertical cavity surface emitting laser(VCSEL),optical fibers and micro-lens arrays as well.The principle,specification and basic structure of each method were introduced and analyzed briefly.Taking the advantage of particle trapping,optical tweezers array was very useful for manipulation of micron size particles,such as cells.Combining with microfluidics and MEMs fabrication,optical tweezer array,the ultraminiature and portable particle sorting system,would be a good choice for space biological research.

Objective To Analyze the effect of community-based integrative intervention on hypertension.Methods Among six residential areas,randomly chose four as the intervention group and the another two as the control group.Then a synthetical intervention was carried out to the intervention group,but no measures to the control.Results In the intervention group,the patients' systolic and diastolic pressure were eventually lower by 5.25 mm Hg than the datum line.The final result was obviously different from the datum line(P0.05).Conclusion The community-based integrated intervention plays a great role in the control of high blood pressure.

Cerebral vasospasm (CVS) is a serious complication of aneurysmal subarachnoid hemorrhage (SAH).Endothelin-1 (ET-1) is an endothelium-derived vasoconstrictor substance.A large number of clinical and basic studies have shown that cerebrospinal fluid and/or ET-1 levels in peripheral blood increases in patients with SAH and play an important role in the occurrence and development of CVS.This article reviews the research status of the role of ET-1 in the occurrence and development of CVS.

Objective:To investigate the relation between the AT 1 receptor gene polymorphism and some biochemical indices of essential hypertension patients. Methods:Sixty-four patients of mild-moderate essential hypertension were not given any anti-hypertension drugs for 5 half lives,then used the PCR-RFLP to detect the AT 1 receptor gene type and measured the basic blood pressure at the same time. After that, fasting serum glucose , serum total cholesterol(TC) , triglyceride(TG) , high-density lipoprotein cholesterol(HDL-C) , low-density lipoprotein cholesterol(LDL-C) , blood urea nitrogen(BUN) , creatinine(Cr) were measured in all subjects. Results:①The frequency of AC gene type in these essential hypertension patients and the C1166 allete of AT 1 receptor gene was 23.4% and 11.7%. ②There was a remarkable difference on TG between two gene groups. ③There were obvious difference on Cr and UA between two gene groups .④There were no obvious difference on Glu, TC ,HDL-C ,LDL-C ,BUN between AC and AA gene type. Conclusion:①The concentration of TG of AC gene type is lower than that of AA , there may be relativity between two gene type. ② A1166/C gene polymorphism may be associated with renal function. AA gene type may have poorer renal function. ③A1166/C gene polymorphism may be not relative with Glu,TCH ,HDL-C ,LDL-C ,BUN.

Objective To explore the factors relating to serum lutein level in elderly patients with early age-related macular degeneration (AMD).Methods 102 early AMD patients diagnosed by international diagnostic criteria were selected.The level of serum lutein was measured by HPLC,and dietary intake was estimated by food-frequency questionnaire (FFQ).The factors relating to serum lutein level were analyzed by Pearson correlation and multiple regression analysis models.Results Serum lutein level was higher in female AMD patients than in male AMD patients [(0.33±0.31) μmol/L vs.(0.21 ±0.19) μmol/L,t=2.21,P＜0.05].Serum lutein level was positively correlated with dietary lutein (r=0.49,P＜ 0.001),but not correlated with age,BMI,and other nutrient intake after adjustment for caloric intake.Dietary lutein was mainly from corn,spinach,leeks,eggs,chrysanthemum,pumpkin,broccoli,lettuce,asparagus and peas.Intakes of spinach,pumpkin,asparagus were significantly associated with serum lutein level.Conclusions Elderly patients with AMD should increase the intakes of lutein-rich vegetables to increase the serum lutein level.

Objective To explore the clinical significance of the precision evaluation of computed tomography angiography and color Doppler image formation technology to the condition of the vascular system in the donor site.Methods From January,2014 to December,2014,CTA and color Doppler were used to examine conditions of the first dorsal metatarsal artery's courser and the size of original caliber in 25 patients with thumb or finger defected.Also the distance between skin and the first dorsal metatarsal artery.The accurate positions and adjacent relations of vessels in donor site were precisely marked and then the vessel original caliber was measured.Results All the first dorsal metatarsal arteries of 25 cases can be appeared clearly in CTA and color Doppler.Blood vessels line and filling results were completely consistent in intraoperative findings.The difference of the vessel original average caliber was statistically significant (P ＜ 0.05) (1.20 ± 0.25 mm,1.41 ± 0.15 mm and 1.3 ±0.2 mm in Doppler,CTA and operation,respectively) while the distance was not significant (P ＞ 0.05)(9.20 ±3.06 mm,10.32 ± 2.76 mm and 0.2 ± 2.6 mm in Doppler,CTA and operation,respectively) All the 25 transplanted toes were survived.Conclusion CTA combined color Doppler image formation technology in thumb or finger reconstruction can objectively reflect the real situation of the vessels in donor sites,and the structural characteristics and classification of anatomy for individualized,and has important clinical value in preoperative foot blood supply assessment.

ObjectiveTo evaluate the correlation between serum anti-Jo-1 antibody level and myositis disease activity in polymyositis/dermatomyositis.MethodsAnti-Jo-1 antibody levels in serum from 148 polymyositis/dermatomyositis patients and 130 healthy controls were measured by both ELISA and immunoblot assay.Disease activity of the anti-Jo-1 antibody positive patients was assessed by the global myositis disease activity score (visual analogue score,VAS) established by the International Myositis Assessment and Clinical Studies(IMACS) Group.The correlation between disease activity and level of serum antiJo-1 antibody was assessed.Comparisons between groups were performed by x2 test or t test.ResultsThe positive rate of ELISA and EUROLINE was 24.3％(36/148) and 27.0％(40/148) respectively.Fever,ILD,arthritis/arthralgia were found to be more predominant in anti-Jo-1 antibody positive patients than those who were anti-Jo-1 antibody negative patients.There was significant positive correlation between the global myositis disease activity score (VAS) and serum level of anti-Jo-1 antibody (r=0.874,P=9.000).Serum antiJo-1 antibody levels,together with global disease activity,were significantly decreased in the 7 patients after treatment.ConclusionAnti-Jo-1 antibody level measured by ELISA is associated with disease activity of PM/DM,and could be a marker of disease activity.
