Presently,tremendous progress has been achieved in the research of acute pancreatitis (AP),which lead to significant changes in many important aspects of the diagnosis and treatment for AP.In 2014,the Pancreatic Surgery Group of Surgery Branch of Chinese Medical Association revised the Guidelines for the Diagnosis and Treatment of Severe Acute Pancreatitis which was published in 2007.In the revised guidelines,the severity of AP is classified as mild acute pancreatitis (MAP),moderately severe acutepancreatitis (MSAP) and severe acute pancreatitis (SAP).The definition of SAP or MSAP depends on the duration of organ failure,which is persistent (＞48 hours) in SAP but is transient (≤48 hours) in MSAP.Modified CT severity index (MCTSI) is used as the imaging evaluation.Acute peripancreatic fluid collection (APFC),acute necrotic collection (ANC),walled-off necrosis (WON) and pancreatic pseudocyst are the local complications.The disease course is divided into 3 stages,including early stage (acute phase),middle stage (evolution phase) and late stage (infection phase).Infected necrosis is an indication for the surgical treatment,but the surgery should not be performed in sterile necrosis.Meanwhile,surgical treatment should follow the delayed principle.Surgical methods that include percutaneous drainage (PCD),minimally invasive surgery and open surgery could be selected separately orjointly.

Diabetic retinopathy is one of the most common and serious microvascular complications of diabetes, and it is a very complex pathological process, displaying multi-factor, multi-stage characteristic in the outcome. Recent studies have shown that the pathogenesis of diabetic retinopathy is closely related to oxidative stress, and antioxidant therapy can effectively improve the condition. Heme oxygenase-1(HO-1)is a widely existing antioxidant defense enzyme, which can reduce the injury caused by oxidative stress and plays an important physiological role. Studies have indicated that in retina HO-1 can be highly induced by hyperglycemia. Moreover, the expression level of HO-1 by man-made changes can accelerate or postpone the diseases progression. That means HO-1 for the diagnosis and treatment of diabetic retinopathy has satisfactory applied foreground. In this article we would like to review the role of HO-1 in diabetic retinopathy.

ObjectiveTo observe the effect of community-based rehabilitation (CBR) on older stroke patients in ability of activities of daily living (ADL).Methods50 older stroke patients were randomly divided into the rehabilitation group and control group. The rehabilitation group was treated with motor function exercise and ADL training, while the control group only took medicine. Two groups were evaluated with Barthel index before and after treatment. ResultsScores of Barthel index on the rehabilitation group were higher than that on the control group after treatment, and there was a significantly difference between two groups (P<0.01). Conclusions CBR has the significant effect on improving ADL in older stroke patients.

Objective To investigate the effects of Kr üppel-like factor 2 ( KLF2 ) on oxidized low density lipoprotein (ox-LDL) induced expression of microRNA-146a (miR-146a) and proinflammatory cyto-kines (MCP-1 and IL-6) in human umbilical vein endothelial cells (HUVECs).Methods Human umbili-cal vein endothelial cells (HUVECs) were cultured and then stimulated with 50μg/ml ox-LDL for 24 hours. HUVECs were infected with adenovirus vectors over-expressing human KLF2 at an appropriate multiplicity of infection.KLF2-siRNA duplexes were transfected into HUVECs to silence the gene expression .HUVECs were collected at time points of 0 h, 3 h, 6 h, 12 h, 24 h and 48 h after infection.Real-time quantitative-PCR was performed to measure the expression of miR-146a at mRNA level.Silenced endogenous miR-146a using LNA-anti-miR-146 a was transfected into HUVECs with lipofectamine 2000 .The levels of MCP-1 and IL-6 in supernatants were detected by ELISA .Results KLF2 remarkably inhibited the expression of miR-146 a in unstimulated and ox-LDL-stimulated HUVECs in a time-dependent manner .The ox-LDL induced ex-pression of miR-146a, MCP-1 and IL-6 in HUVECs were significantly decreased by KLF2.Silenced expres-sion of miR-146a downr-egulated the ox -LDL induced expression of MCP-1 and IL-6 in HUVECs.Moreover, silenced miR-146 a could partly reverse the inhibitory effects of KLF 2 on ox-LDL induced expression of MCP-1 and IL-6 in HUVECs.Conclusion KLF2 inhibited ox-LDL induced expression of MCP-1 and IL-6 in HUVECs partly through down-regulating the expression of miR-146a.

In present paper,we studied three kinds of method of assay for IL-1:thymocyte proliferation assay;L_(?) cell proliferation assay and pyrogen assay.Stimultaneously we used ~(125)I-UdR in stead of ~3H-TdR.The results show that all of three kinds of method of assay for IL-1 can measure IL-1 activity of supernatants from cultured rat alveolar M? stimulated by LPS in vitro.It suggests that ~(125)I-UdR can incorporate into DNA synthesis of cell and mouse fibroblast cell line L_(?) can response to IL-1 of supernatant from cultured rat alveolar M? stimulated by LPS.
