Chinese Journal of Nephrology 2010;26(5):339-342
Objective To investigate the interrelationship among urinary albumin elimination rate(UAER),serum adiponectin(ADPN)and blood glucose level in patients with type 2 diabetic nephropathy(DN). Methods A total of 89 type 2 diabetic patients and 30 healthy people as control were enrolled in the study.According to UAER,the diabetic patients were divided into three groups:normal group(35 cases,UAER<30 mg/24 h),microalbuminura group (32 cases,UAER 30-300 mg/24 h)and macroalbuminura group(22 cases,UAER>300 mg/24 h).Serum adiponectin was measured by ELISA.Body mass index (BMI),waist hip radio(WHR),fasting plasma glucose(FPG),2-hour plasma glucose(2hPG),glycated haemoglobin(HbAlc),blood lipid and UAER were measured routinely.Data were compared among groups. Results Serum adiponectin level was lower in diabetic patients than that in healthy control group(P<0.05).Among diabetic patients.serum adiponectin of macroalbuminura group was significantly higher than that of normal and microalbuminura groups[(67.74±14.89)vs(39.36±13.92),(54.38±10.14)ng/L,P<0.051.Multiple regression analysis showed 2hPG,HbAlc,BMI,disease course,UAER and DBP were closely associated with the level of serum adiponectin. Correlation analysis indicated serum adiponectin was positively correlated with age (r=0.255), disease course (r=0.405), HDL (r=0.501)and UAER (r=0.843); while negatively with HbAlc (r=-0.479), FPG (r=-0.436), 2hPG(r=-0.418),BMI (r=-0.479) and WHR (r= -0.531), all P<0.01. Conclusions Serum adiponectin is positively correlated with UAER and negatively correlated with FPG. Blood glucose level is one of the main factors affecting serum adiponectin. Strict controlling of blood glucose level is beneficial to higher level of ADPN.

International Journal of Surgery 2011;38(6):393-395
Neural invasion is an important invasion pathway of pancreatic cancer.New research shows that neural invasion of pancreatic cancer related genes in the sequential role effect,through the cell signal transduction,regulation of specific growth factors,adhesion molecules,matrix metallopmteinase and other related systems,then changed in the generation,resulting in the cancer cells invasion of the nerve tissue eventually.We reviewed the progress of neural invasion of pancreatic cancer in this paper.
8.Directed forgetting: an ERP research on postgraduate
Chinese Journal of Behavioral Medicine and Brain Science 2011;20(6):528-530
Objective To investigate neural correlates of directed forgetting. Methods ERP was recorded from 12 healthy postgraduates while they performed a directed forgetting task based on the item-cueing method. During the study phase, each word was followed by a cue indicated that it need to be remembered, to be forgotten or just to be viewed. During the test phase, subjects were asked to make an old/new recognition response. One-way ANOVA of repeated-measurement and paired comparisons were carried out for the cue factor. Results Both of the accuracy and reaction time of the TBR group were significantly superior to those of the other two groups. No significant behavioral effect was found between the TBF group and the TBV group. In the study phase, statistical parametric mapping of ERP suggested the cue effects were presented in the frontal poles ( 200~300 ms ) and the parietal regions (300~400 ms) ,the left fronto-parietal and the right occipital region (450~700 ms). The difference between the TBF and the TBV was significant in the left parietal area (500~525 ms) and has the significant trend in the right frontal area ( 350~600 ms). In the retrieval phase, the old/new effects of ERP occurred in the left fro-nto-temporal (300~450 ms) for the TBF cue. Conclusions The TBF cue and the TBV cue have the equivalent behavioral performance. During the study period, the activation of the right frontal lobe and the left parietal suggests the active inhibition evoked by the TBF cue. And the TBR cue can enhance the rehearsal function of left hemisphere and improve the memory performance of words. The retrieval of the items of TBF is based on more familiarity and less recollection.
