Objective To evaluate the value of percutaneous endoscopic gastrostomy (PEG) in the treatment of amyotrophic lateral sclerosis (ALS) patients with dysphagia. Method Sixty-five ALS patients underwent PEG from April 2005 to July 2010 were analysed retrospectively. Results All the 65 patients underwent PEG,and 2 patients failed because of dyspnea. Totally 63 patients were intubated successfully,the successful rate was 96.9%(63/65). The operation time was 8-17 min. Two patients had local infection.After 3 months, the body mass index was increased from (18.3 ± 1.0) kg/m2 to (19.7 ± 1.2) kg/m2(t = 15.8,P ＜ 0.01), without peritonitis, migration of the gastrostomy tube and other complications. Conclusions PEG is a safe method with a low complication for ALS patients to get enteral nutrition. Dyspnea is the main reason of failure.

Objective To investigate the effects of exogenous hydrogen sulfide on brain edema and injury and their mechanisms. Methods Sixty male SD rats were randomly divided into a sham operation group, an ischemia-reperfusion group, a 30 ppm hydrogen sulfide group, and a 60 ppm hydrogen sulfide group (n =15 in each group; 1 ppm =1 mg/L). A model of focal cerebral ischemia for 2 h and reperfusion for 24 h was induced by middle cerebral artery occlusion. The neurological scores were observed after 24 h cerebral ischemia-reperfusion. The cerebral infarction volume, the degree of brain edema, and the changes of blood-brain barrier permeability were measured. Western blotting was used to detect the expressions of occludin and zonula occludens-1 protein (ZO-1) in ischemic penumbra. Results Compared with the ischemia-reperfusion group, the neurological function scores in the 30 ppm and 60 ppm hydrogen sulfide group significantly increased in a dose-dependent manner (al P <0.05) and the neurological deficits and infarct volume reduced (al P < 0.05), and the
brain edema aleviated (al P < 0.05). The content of Evans blue in the ischemic brain tissue in the ischemia-reperfusion group increased significantly compare with the sham operation group (0.74 ±0.14 μg/100 mg vs. 0.19 ±0.06 μg/100 mg; P <0.05). The content of Evans blue in the brain tissue in the 30 ppm hydrogen sulfide group (0.55 ±0.10 μg/100 mg ) and the 60 ppm hydrogen sulfide group (0.35 ±0.08 μg/100 mg ) decreased significantly compared with the ischemia-reperfusion group (al P < 0.05), among them the 60 ppm hydrogen sulfide group was significantly lower than the 30 ppm hydrogen sulfide group (P <0.05). Western blot analysis showed that expression levels of occludin in penumbra (0.621% ±0.101% vs.0.787% ±0.087% vs.0.453% ± 0.127%; P <0.05) and ZO-1 (0.602% ±0.118% vs.0.778% ±0.805% vs.0.426% ±0.146; P <0.05) in the 30 ppm and 60 ppm hydrogen sulfide groups increased significantly compared with the ischemia-reperfusion group, among them, the expression levels of occludin and ZO-1 in the 60 ppm hydrogen sulfide group were significantly higher than those in the 30 ppm hydrogen sulfide group (al P < 0.05). Conclusions Inhalation of exogenous hydrogen sulfide can significantly attenuate brain edema after ischemia-reperfusion in a dose dependent manner, reduce infarct volume, and improve neurological function.Their mechanisms may be associated with inhibiting the downregulated expressions of occludin and ZO-1 and maintaining the integrity of the blood-brain barrier.

Objective To investigate the myocardium protective effect of immunoinflammatory response induced by preinfarction angina. Methods Eighty-eight patients of acute myocardial infarction were divided into preinfarction angina group (48 subjects) and sudden onset group (40 subjects). The incidence of severe arrhythmia,heart failure,cardiac shock and in-hospital mortality were assessed in the two groups. The myocardial infarction size,ventricular function,coronary angiography were compared between the two groups. Some immunoinflammatory markers levels were detected. Results In preinfarction angina group,the incidences of severe arrhythmia,heart failure,and in-hospital mortality were lower (P

Objective To investigate the characteristics of etiology,efficacy of endoscopic management for recurrent idiopathic pancreatitis (RIP).MethodsThe clinical data of 58 cases of RIP diagnosed in our hospital from April 2005 to April 2011 were retrospectively analyzed.All the patients underwent endoscopic retrograde cholangiopancreatography (ERCP),and patients with suspected sphincter of Oddi dysfunction received manometry.According to the clinical and ERCP manifestations,the etiologies of RIP were determined and individualized endoscopic treatment was applied.The patients were followed-up postoperatively about the improvement of abdominal pain and recurrence of RIP.ResuItsFifty-eight patients (29 males,29 females) were suffered from acute pancreatitis from 3 to more than 10 times.The etiologies were as follows:29 cases of biliary microlithiasis,19 case of sphincter of Oddi dysfunction ( 16 cases of pancreatic type,3 cases of mixed type),4 cases of anomalous arrangement of the pancreaticobiliary duct,and 6 cases of normal manifestations at ERCP.Biliary sphincterotomy alone was performed in 33 patients,while both biliary and pancreatic sphincterotomy was performed in 8 patients,and pancreatic sphincterotomy alone was performed in 17 patients,after sphincterotomy,pancreatic stent insertion was performed in 24 patients.The follow-up data was obtained from 41 out of 58 patients,the follow-up period ranged from 3 ～ 67 months ( average 33 months).During this period,9(22.0％ ) patients suffered from RIP,and the treatment efficiency was 78％.ConclusionsBiliary microlithiasis and sphincter of Oddi dysfunction are the main causes of RIP.Drink could induce RIP.ERCP has definite treatment efficacy for RIP.
