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 study the expression of acid secreted proteins that are rich in cysteine protein (SPARC protein)in gastric adenocarcinoma tissue and its relationship with the prognosis of patients with gastric cancer.Methods In order to detect SPARC protein expression levels in gastric adenocarcinoma ,104 primary gastric adenocarcinoma samples as well as 30 normal gastric tissues adjacent to carcinoma were studied by immu-nohistochemistry .Results The positive rate of SPARC protein in 30 cases of gastric mucosa adjacent to carcino-ma is 20%,and with weak expression or no expression;The positive rate in 104 cases of gastric cancer tissues was 76.1%,the difference was significant(P<0.01).The high expression rate of SPARC and lymph node metastasis in gastric adenocarcinoma were positively correlated (P<0.01).The SPARC expression rate of well and moderate differentiation of gastric adenocarcinoma were significantly lower than that of the low differentiation ( P<0 .05 ) . The average survival time of gastric cancer patients with high SPARC expression was 27.4 months.However,the average survival time of the patients with low SPARC expression was 40.9 months.The difference was significant (P<0.05).Conclusion SPARC protein is mainly high expressed in gastric cancer stromal tissue cells and fi-broblasts .The expression level of SPARC protein is significantly associated with lymph node metastasis and tumor differentiation degree .The high expression of SPARC patients survival time is short and the prognosis is poor . However ,SPARC protein is not an independent prognostic factor .

An endogenous element-label plus exogenous element-tag strategy was proposed for inductively coupled plasma mass spectrometry ( ICP-MS) to screen and discriminate a family of ultratrace but biological important biomolecules. The feasibility of this novel idea has been demonstrated when setting seleno ( SeCys) and Se-containing ( SeMet) proteins ( peptides) as an example. Se-label naturally occurring in the biomole-cules acts an identifier for picking them up out of large amount of various coexisting proteins ( peptides) , and CH3 Hg-tag that can bind to SeCys but not SeMet fulfills the task of discriminating seleno and Se-containing ones based on the Se and Hg signals on ICP-MS. After confirmed using SeCys and GPx1, the Se-Hg dual-element labeling strategy together with ICP-MS was applied to screen and discriminate seleno and Se-contai-ning proteins ( peptides) in the water-soluble extracts of Se-enriched yeast, and seven selenoproteins ( pep-tides) were detected with both 202 Hg and 82 Se signals out of fifteen Se-containing species using RPLC/ICP-MS, providing valuable information for further identification using a high-resolution structure-selective mass spectrometer. This endogenous element-label plus exogenous element-tag dual-element approach implies that ICP-MS is not only able to quantify targeted proteins ( peptides) but also helpful to recognize targeted proteins during a discovery-based proteomic study.
