Objective To evaluate the changes in the expression of DJ-1 protein during myocardial ischemia-reperfusion (I/R) in diabetic rats.Methods Fifty male Sprague-Dawley rats,weighing 220-280 g,were used in this study.Type 1 diabetes mellitus was induced by intraperitoneal streptozotocin 65 mg/kg and confirmed by fasting blood glucose ＞ 16.7 mmol/L.Forty animals with type 1 diabetes mellitus were randomly divided into 3 groups:diabetes group (group D,n =10),diabetic sham operation group (group DS,n =15) and diabetic I/R group (group DIR,n =15).Another 10 non-diabetic rats in which citrate buffer 6 ml/kg was injected intraperitoneally were served as control group (group C).Myocardial I/R was produced by occlusion of the anterior descending branch of left coronary artery for 30 min followed by 120 min reperfusion in group I/R.At 120 min of reperfusion,5 rats were sacrificed and myocardial specimens were c(on)tained for determination of infarct size in groups DS and DIR,and 10 rats were sacrificed and myocardial specimens were obtained for microscopic examination and for determination of cell apoptosis,malondialdehyde (MDA) content,superoxide dismutase (SOD) activity and expression of DJ-1 and phosphatase and tensin homologue (PTEN) protein.Apoptotic index (AI) was calculated.Linear correlation between the expression of DJ-1 protein and MDA content,SOD activity,AI and expression of PTEN protein was analyzed.Results Compared with group DS,the myocardial infract size was significantly increased in group DIR (P ＜ 0.05).Compared with group C,MDA content and AI were significantly increased,SOD activity was decreased,the expression of DJ-1 was down-regulated,and the expression of PTEN protein was up-regulated in groups D,DS and DIR (P ＜ 0.05).Compared with groups D and DS,MDA content and AI were significantly increased,SOD activity was decreased,the expression of DJ-1 was down-regulated,and the expression of PTEN protein was up-regulated in group DIR (P ＜ 0.05).There was no significant difference in the parameters mentioned above between groups D and DS (P ＞ 0.05).There was linear correlation between the expression of DJ-1 protein and MDA content,SOD activity,AI and expression of PTEN protein and the correlation coefficients (r) were-0.734,0.593,-0.818,and-0.812 in turn.Conclusion Down-regulation of DJ-1 protein expression is involved in myocardial I/R injury in diabetic rats via decreasing anti-oxidative stress responses and upregulating PTEN protein expression.

Objective To explore influence of thoracic duct ligation on lipid metabolism after esophagectomy. Methods Seventy-four patients with esophageal cancer received esophagectomy were divided into two groups by their thoracic duct ligation, 39 in ligation group and 35 in non-ligation group. All the patients were fed with nutrients through nasal-duodenal tube placed during operation from the 1 st day to the 8th day after surgery, and started taking liquid diet on the 6th day. Blood specimens were collected from the patients on the 1st day after admission, the 9th day, one month and three months after surgery,respectively for biochemical analysis,including determinations of total cholesterol(TC),triglyeeride(TG),high-density lipoprotein-cholesterol ( HDL-C) and low-density lipoprotein-cholesterol ( LDL-C) . Databetween the two groups were compared with statistical analysis. Results No significant difference in plasma levels of TC, TG and HDI.-C was found between the two groups at varied time points. Plasma level of LDL-C in the ligation group significantly decreased on the 9th day after surgery, as compared with that in the nonligation group ( P ＜ 0. 05), and went down to the lowest level one month after surgery. Conclusions Chylomicron was blocked to enter blood stream and production of LDL-C decreased by thoracic duct ligation,which affect lipid absorption and metabolism leading to poor early nutrition in patients with esophagealsurgery due to slower establishment of collateral circulation.

Objective To assess the role of dynamic contrast-enhanced MRI for diagnosis and differential diagnosis of prostatic cancer. Methods Six volunteers, 32 patients with benign prostatic hyperplasia and 13 patients with biopsy-proven prostatic cancer underwent MR imaging. Dynamic MR with Gd-DTPA (gadolinium-diethylene triamine pentaacetic acid) bolus enhancement was performed followed by post-contrast T 1-weighed imaging. The signal intensive value in dynamic MRI was measured and calculated to draw the time-signal intensity curve of normal peripheral zone, prostatic cancer and benign hyperplasia. Results In dynamic MRI, the normal peripheral zone were enhanced mildly and slowly. The lesion enhancement of benign prostatic hyperplasia in 32 patients were obvious in early phase (60 s) and strengthened gradually, and then went to decrease in late phase (240 s) after peak value. The lesions in 9 of 13 cases with prostate cancer were enhanced obviously in early phase (60 s) and washed out rapidly in late phase, and the peak value was located on early phase. Conclusions In dynamic MRI, the enhancement of normal peripheral zone, prostate cancer and benign hyperplasia were different significantly. Dynamic MRI was very useful in the diagnosis and differentiation of prostate cance.

Depression and insomnia are intimately related. Depressed patients usually manifest sleep discontinuity and early awakening, reduced or no slow wave sleep (SWS) and shortened latency of rapid eye movement (REM) sleep. These sleep abnormalities are very similar to those caused by over activated hypothalamic-pituitary-adrenal (HPA) axis with stress. Therefore, the animal models developed by post-traumatic stress disorder or chronic unpredictable mild stress could be used to evaluate drugs which have effects of both anti-depression and improvement of sleep quality, and to provide a more reliable platform for further studis on the mechanisms of depression and accompanied insomnia. This review mainly focuses on the typical features of sleep disturbance of depression, possible pathophysiological mechanisms, establishment of animal stress models and analysis of their abnormal sleep characteristics.

To prepare rivastigmine liposome, rivastigmine was loaded into liposome via ammonium sulfate gradient method. Its pharmacokinetic profile in rats was evaluated after intranasal administration. The size, zeta potential, entrapped efficiency and release of rivastigmine from the liposome in vitro were determined. Plasma concentration of rivastigmine was determined by high performance liquid chromatography-tandem mass spectrometry (HPLC/MS) using antipyrine as internal standard. The pharmacokinetic parameters were calculated by DAS 2.0. The entrapped efficiency of rivastigmine liposome was (33.41 +/- 6.58) %, with the mean diameter of 154-236 nm and zeta potential of (-10.47 +/- 2.41) mV. The release behavior of rivastigmine was fitting the first order equation in vitro. The pharmacokinetic studies indicated that the C(max), T(max) and AUC(0-infinity), of rivastigmine liposome were (1.50 +/- 0.15) mg x L(-1), 15 min and (89.06 +/- 8.30) mg x L(-') x min, respectively. Rivastimine liposome was absorbed rapidly, and could reach a certain concentration in rat plasma after intranasal delivery.
