Objective To investigate the expression of TGF-β activated kinase1 (TAK1),phosphoryted TAK1 (p-TAK1) and the density of tumor associated macrophages (TAM) in human pancreatic carcinoma tissues and pairing adjacent normal pancreatic tissues,and explore their relationship.Methods The expression of TAK1,p-TAK1,CD68 (the marker of tumor associated macrophages) proteins in 57 samples of pancreatic cancer tissues and 35 samples of pairing adjacent normal pancreatic tissues were detected by immunohistochemical method,then the density of TAM was evaluated.The relationship between the protein expression and TAM,and the relationship between them and clinicopathologic parameters were examined using SPSS 18.0 software,and the independent risk factors of TNM staging were analyzed by multivariate logistic regression.Results TAK1 and p-TAK1 were positively expressed in 42.1％ (24/57) and 40.4％ (23/57) pancreatic carcinoma tissues,significantly higher than adjacent normal pancreatic tissues [14.3 ％ (5/35) and 11.4％ (4/35)];the proportion of pancreatic carcinoma tissues with high density TAM was 38.6％ (22/57),higher than that of adjacent pancreatic tissues [8.6％ (3/35)],the differences were statistically significant (P＜0.05).TAK1 expression was positively related to tumor size,tumor differentiation,lymph node metastasis,distant metastasis and clinical staging;p-TAK1 expression was positively related to tumor differentiation,lymph node metastasis,distant metastasis and clinical staging;the density of TAM was positively related tumor differentiation,lymph node metastasis,distant metastasis and clinical staging (all the P values were less than 0.05).The expression of TAK1 and p-TAK1were positively correlated with the density of TAM (P ＜0.001).Multivariate logistic regression analysis showed that high density of TAM was independently associated with advanced clinical staging (P =0.002,OR =129.5,95％ CI 6.2 ～2718.6).Conclusions TAK1 pathway and TAM may play an important role in the pathogenesis and progression of pancreatic cancer,and there may be synergy effect between them.

Objective To investigate the correlation between the percentage of systolic stenosis of the mural coronary artery (MCA) and the length and depth of the myocardial bridge using dual-source computed tomography (DSCT). Methods Four hundred and fifty patients suspected of coronary artery disease (CHD) underwent dual-source computed tomography coronary angiography (DSCTCA). The images were analyzed by 2 radiologists independently. When consistency was obtained among the independent results, the diagnosis of MB-MCA could be confirmed. The length of MCA and depth of MB were measured. All data were reconstructed by every 5% R-R interval, the diameters of MCAs during the whole cardiac cycle were reviewed and measured, the phases were detected when the diameters of MCAs were maximal and minimal, the systolic stenosis rate of MCA was calculated,Pearson correlation analysis was used to analyze the relation between length, depth, and degree of systolic stenosis of the MCAs. Results One hundred and ninety-two sites of MB-MCA were found in 163 ( 36. 2% ) of 450 patients. Of the 192 sites, 72 were completely surrounded by myocardium. Among the 30 MCA sites chosen from these 72 sites, the minimal diameters were found at 30%--35% R-R reconstruction interval in 27 sites(90.0% ), and the maximal diameters were found at 70%--80% R-R reconstruction interval in 27 sites (90. 0% ). A significant correlation was not found between systolic stenesis and the length of the MB ( r = 0. 096, P > 0. 05 ) but was found with the depth of the MB ( r = 0. 675, P < 0. 01 ) of the MCA. Conclusion The minimal and maximal diameters of the MCA usually emerged in 30%--35% R-R reconstruction interval and 70%---80% R-R reconstruction interval on DSCTCA, respectively. The degree of systolic stenosis of MCA significantly correlates with MB depth but not length.

This study was to evaluate the effect of individualized health education on blood glucose control in type 2 diabetic(T2D)Patients.Two hundred and thirty-eight T2D patients were randomly received individualized diabetes education(intervention group)or general education(control group).At 48 week,change of blood glucose control from baseline was observed.The blood glucose level and HbA1c in the intervention group were lower than those in the control group[(7.1±0.8)vs (9.3±6.5)mmol/L,(7.0 ±1.3)%vs(8.0%±1.0)%;P＜0.05].Thus,individualized diabetes education might be helpful for blood glucose control in T2D patients.

Kidney is a highly vascularized organ and peritubular capillary network constitutes the critical component of its microvascular system. Peritubular capillaries, as the main vessels for blood supply in renal tubules and renal interstitium, involve in important physiological processes in renal tubules such as energy metabolism, substance secretion and reabsorption. In recent years, it has been demonstrated that ischemia-reperfusion injury, rejection and renal fibrosis during kidney transplantation would result in compromised structural integrity and decreased number in peritubular capillaries, thus leading to interstitial fibrosis in renal allograft, which would seriously affect the long-term stability of renal function in the renal allograft. Therefore, we reviewed the structure and function of peritubular capillary, peritubular capillary and ischemia-reperfusion injury, rejection and renal allograft fibrosis, focusing on the mechanism for peritubular capillary injury in kidney transplantation and the specific changes manifested, with the aim of providing a reference for preventing and treating perioperative complications in kidney transplantation and improving the long-term prognosis of grafts.

During the uric acid production, excretion and reabsorption in the liver, kidney and intestine, several uric acid transporter proteins are involved in these processes. A large number of studies have shown that glucose transporter 9 plays an important role in the uric acid transport in the liver, kidney and intestine, and participates in the uric acid reabsorption. The ATP-binding cassette superfamily G member 2 is mainly expressed in the apical membrane of the proximal tubular epithelial cells of the kidney, which is involved in the uric acid secretion. The multidrug resistant protein 4 is expressed in the apical membrane of the renal tubular epithelial cells, which transfers uric acid from the renal tubular epithelial cells into the renal tubular lumen. The urate-anion transporter 1 as well as the organic anion transporters 1 and 3 are all the organic anion transporters belonging to the SLC22 A family of transmembrane transporters, and all participate in the uric acid transport in the kidney, especially the uric acid secretion and excretion. In this review, we summarize the research progress of these uric acid transporters, focusing on their effects on the regulation of the serum uric acid balance.
