Researches in type 2 diabetes and non-alcoholic fatty liver disease have been made in recent years.The intimate connection between these two diseases has been analysed and explored.Whether non-alcoholic fatty liver disease is a hepatic complication of type 2 diabetes remains to be elucidated.The poor outcome of liver disease in patients with type 2 diabetes should be emphasized.

The progress in nonalcoholic fatty liver disease(NAFLD) research has shown an important role of hepatic steatosis in triggering insulin resistance and glucose/lipid metabolic disorders.As an early reversible therapeutic target for metabolic diseases,NAFLD has attracted increasing attention from endocrinologists and gastroenterologists,as well as deeping the studies in this field.Based on the recent progress in NAFLD research,this review mainly presents the new understanding and concept of NAFLD,discusses the features of the new guidelines and concensus for NAFLD treatment,and introduces some updated developments in NAFLD diagnosis and therapy.Furthermore,future directions of NAFLD research are also predicted in the article.

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disorder, affecting 10%-24% of the general population, and the incidence is much higher (70% -80% ) in type 2 diabetic patients. Recent studies indicate that fatty liver is an emerging problem in the Asia-Pacific region and China. The community prevalence of NAFLD in Shanghai is 15%. A large body of evidences suggests that NAFLD is the hepatic manifestation of the metabolic syndrome. NAFLD is not only associated with the metabolic syndrome, it also predicts the development of type 2 diabetes and cardiovascular disease (CVD). The liver is a central organ for controlling and regulating glucose and lipids metabolism; intrahepatocellular lipid accumulation plays a key role in the development of metabolic-ally related disorders. It is crucial that specialists, especially endocrinologists, and practising clinicians should be aware of the strong association between NAFLD and increased risks of diabetes and CVD, NAFLD should be diagnosed correctly and defined timely in regarding its role as risk factors of underlying diabetes and CVD.

Three cellulose derivatives were synthesized and used as chiral stationary phases based on silica gel.The effects of adsorbances on the column numbers and stabilities have been investigated.These stationary phases exhibited high chiral recognition for various racemates.At the same time,the on-line curves of polarimeter were obtained by high performance liquid chromatography with polarimeter as on-line detector.

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.

Objective To explore the before taking finasteride on transurethral plasmakinetic resection of prostate(TUPKVP)patients about IPSS,QOL,Qmax,PVR and other indicators.Methods 180 cases with benign prostatic hyperplasia were randomly divided into observation group and control group,90 cases in each group.Observation group and control group were given conventional therapy and the observed patients took 5 mg of finasteride everyday one week before surgery,all patients were followed up for 1 month.The two groups of TUPKVP patients were compared about IPSS,QOL,Qmax and PVR,intraoperative blood loss,operation time,irrigation fluid volume indicators.Results 180 patients were given successfully TUPKVP surgery.IPSS,QOL,Qmax and PVR contrast were significantly improved after treatment(t=5.11,7.01,3.06,6.17,11.82,4.13,4.52,5.17,all P＜0.05).IPSS,Qmax,PVR of the observation group after treatment was significantly better than that of the control group(t=11.35,5.26,3.12,all P＜0.05),the QOL difference between the two groups after treatment was not statistically significant(P＞0.05).The cure rate of the observation group was 87.8％,which was significantly higher than 63.33％ in the control group(x2=14.56,P＜0.05).Intraoperative flushing fluid volume,intraoperative blood loss,duration of surgery in the observation group were significantly different compared with the control group,(t=21.15、43.12,5.33,all P＜0.05).Conclusion The preoperative taking finasteride can reduce TUPKVP blood loss and flushing fluid volume,shorten operation time and effectively improve the security of the operation.

Microsomal triglyceride transfer protein (MTP) is a key transfer protein in lipid metabolism and is mainly expressed in the hepatocytes and enterocytes.It plays an important role in transferring triglyceride as well as in assembly and secretion of very low density lipoprotein.Recent studies have shown that MTP is closely related to the onset and development of non-alcoholic fatty liver disease.

Objective To study the effect of caveolin-1 on renal injury and the expression of tight junction proteins in MRL/lpr mice kidney.Methods The mice were divided into 4 groups:5 mice in the normal control group (BALB/c mice);the MRL/lpr lupus mice (n=18) were randomly divided into the MRL/lpr group in which 6 mice were included;the negative control group in which 6 mice were included;the caveolin1 transfection group in which 6 mice were included.The changes of urine protein,the levels of urea (BUN) and creatinine (Cr) were detected.The expressions of claudin-5,occludin,ZO-1 and caveolin-1 protein were determined by western bloting.Analysis of variance was used to determine statistical significant differences between the two groups.A significance level of 0.05 was considered as signigicant.Results Compared with the control group,24 h urine protein [(2 894±437) mg,(412±72) mg],BUN [(8.7±1.5) mmol/L,(6.9±0.4) mmol/L],Cr [(106±22) μmol/L,(85±4) μmol/L] were significantly increased,level of caveolin-1 protein increased (265±17,61±6),the level of occludin (114±12,190±12),claudin-5 (60±5,80±6) and ZO-1 (98±11,206±15) protein decreased in the MRL/lpr group (P＜0.05).After caveolin-1 transfection,the levels of urinary protein [(1 253±249) mg,(2 894±437) mg],BUN [(6.5±1.3) mmol/L,(8.7±1.5) mmol/L],Cr [(78±17) μmol/L,(106±22)μmol/L] were significantly decreased,and the levels of occludin (218±16,114±12),claudin-5 (87±6,60±5)ZO-1 (313±17,98±11) were increased (P＜0.05).Conclusion The expression of caveolin-1 protein in the renal tissues of lupus nephritis increases.Caveolin-1 can reduce the expression of tight junction proteins and contribute to progres-sion of lupus nephritis.

Objective To investigate the clinical value of Holter monitor(DCG) in the diagnosis and treatment of dilated cardiomyopathy (DCM).Methods According to NT-proBNP ＞ 2 000pg/mL,left ventricular ejection fraction (LVEF) ≤40％,New York Heart Association (NYHA) rated Ⅲ-Ⅳ,67 patients with DCM were divided into the high risk group and nonhigh risk group.All kinds of arrhythmia patients proportion was compared between the two groups,in order to understand the risk factors of DCM and arrhythmias.Results In high risk group,18 cases had ventricular tachycardia,the incidence rate was 66.7％,which was significantly higher than that of non high risk group (2 cases,5.0％) (x2 =29.271,P ＜ 0.01).While other arrhythmia,atrial premature beats,single premature ventricular contraction,atrial fibrillation and so on,had no statistical difference (P ＞ 0.05).Conclusion The DCM patients with various types of arrhythmia,ventricular tachycardia in patients directly influence the severity and prognosis,Holter monitor has an irreplaceable role.
