Pancreatic encephalopathy (PE)is one of the severe complications of severe acute pancreatitis (SAP).Early diagnosis mostly depends on the history of disease as well as clinical symptoms and signs.PE progresses rapidly and is often complicated by multiple organ dysfunction,and it may finally develop into multiple organ failure with a high fatality rate if not treated in time.It is currently known that de-myelination is one of the important pathological features of this disease,with fat -soluble demyelination of cerebral gray matter and white matter,as well as inflammatory changes such as hemorrhage and edema.The target antigen of demyelinating lesions,however,is myelin basic protein (MBP).This paper reviews the changes in MBP levels in the demyelinating lesions of the central nervous system among PE pa-tients,with the purpose of providing clues for the early diagnosis and prognostic study of demyelinating lesions in PE.

BACKGROUND: Physical training induces adaptation changes on physiological function and anatomic structure of body, which significantly exist in individuals. Individual variation responses to physical training is determined by gene polymorphism. OBJECTIVE: To summarize the research progress on the association between gene polymorphism and exercise training sensitivity in recent years. RETRIEVAL STRATEGY: A computer-based search of Pubmed database was undertaken to identify the articles published from January 2002 to December 2006 with the key words of "gene polymorphism, endurance training, strength training, aerobic training" in English. Simultaneously, China Journal Full-text Database was searched for the relevant articles published from January 2002 to December 2006 with the same key words in Chinese. Totally 58 relevant articles were collected after the first trial. Inclusive criteria: ①articles on association between gene polymorphism and endurance training, ②articles on association between gene polymorphism and strength training, ③articles on association between gene polymorphism and hypoxia training. LITERATURE EVALUATION: The articles collected were prospective cohort studies on association of gene polymorphism with some physiological and biochemical parameters response to physical training. DATA SYNTHESIS: ①The individual variation responded to physical training in physiological and biochemical parameters are mostly determined by genetic factors, such as gene polymorphism.②Recently, there are lots of studies on association of gene polymorphism with physiological and biochemical parameters response to endurance training, strength training and hypoxia training.③Mostly studies indicate that there are associations among physiological and biochemical parameters response to endurance training, strength training and hypoxia training and I/D polymorphism in ACE gene, C1772T in HIF-1? gene and so on. CONCLUSION: Although gene polymorphism is a genetic marker of determining the physiological phenotype of human, the various genetype of the same gene polymorphism can cause different sensitivity change of physiological phenotype in the different races response to training. With the research progress on association between gene polymorphism and physical training sensitivity, it will indicate its related mechanism.

Objective To investigate the digital subtraction angiography (DSA) manifestations and clinical value of interventional embolization of renal artery with severe hemorrhage following percutaneous nephrolithotomy (PCNL).Methods 34 patients with severe hemorrhage following PCNL from Feb 2012 to Jun 2015 were subjected to perform renal arterial DSA, which was followed by super-selective renal arterial embolization (SRAE) with steel micro-coils and guglielmi detachable coils together with or without biological glue (GLUBRAN2). The patients were followed up for 6 ~ 12 months.Results Of the 34 patients, DSA examination showed that renal artery pseudoaneurysm (RAP) was found in 22 (64.7%), renal arteriovenous ifstula (RAVF) in 8 (23.5%) and RAP associated with RAVF in 4 (11.8%). Successful embolization with single session was achieved in all 34 patients. Both the technical success rate and the hemostasis rate were 100.0%. Meanwhile, the renal tissue and function were mainly reserved and no serious complication of embolization was observed. No hematuria recurrence or renal function failure appeared in all patients during the follow-up period. In 26 patients, different degree of embolism syndrome was observed after the treatment.Conclusions Renal artery pseudoaneurysm and renal arteriovenous ifstula are the main types of renal artery injury resulting in severe hemorrhage after percutaneous nephrolithotomy. Super-selective renal arterial embolization (SRAE) with steel micro-coils and guglielmi detachable coils together with or without biological glue (GLUBRAN2) is a minimally invasive method that can promptly stop the renal bleeding, and preserve the renal tissue and function to the greatest possible advantage. Therefore, this technique should be regarded as the ifrst choice in the treatment of the patients who suffered from severe hemorrhage occurred after PCNL.
