Objective To investigate the effect of melatonin on serum malondialdehyde (MDA), NF-κB, tumor necrosis factor-α(TNF-α) andβ2-microglobulin (β2-MG) levels in secondary brain damage following intracerebral hemorrhage patients.Methods 90 patients secondary brain damage following intracerebral hemorrhage were divided into experimental group and control group, 45 cases in each group.The control group were given conventional treatment after surgical removal of hematoma, and the experimental group, on the basis of control group, were given melatonin capsule (6 mg melatonin) , orally, once a day, for 2 weeks treatment.The levels of MDA, NF-κB, TNF-αand β2-MG in patients’ serum were detected.Results The MDA, NF-κB, TNF-αand β2-MG levels after treatment significantly decreased compared with before treatment in two groups (all P<0.05), and the above indexes in experimental group significantly decreased compared with control group ( P <0.05 ).Conclusion Melatonin can significantly reduce the levels of MDA, NF-κB, TNF-αand β2-MG levels in brain injury patients with cerebral hemorrhage, and repair brain damage, which has a guiding significance for clinical use.

Pancreatitis is a common complication of endoscopic retrograde cholangiopancreatography( ERCP). Patient selection and risk factors assessment are critical elements for preventing post-ERCP pancreatitis(PEP). Pancreatic stent plays a role in prevention of PEP,but with limitations. Rectal administration of NSAIDs is an effective way to reduce the incidence of PEP. Effect of other drugs for preventing PEP is unclear. This article reviewed the advances in study on PEP.

Results The post-operative mortality was 3.7 %,and 96.3 % of patients were in NYHA class Ⅰ and Ⅱ after surgery.During fol- low-up,there were 20 deaths and 23 reoperations.Survival at 7-year,10-year and 15-year was 91%,88% and 70%,respectively. Freedom from reoperation at 7-year and 10-year was 94% and 86%,respectively.Conclusion Valve repair in mitral leaflet disease is a standard technique,with a good operative results.

AIM:Neural stem cells(NSCs)and their supporting factors are related to nerve regeneration after central nerve injury, but there are few evidences for the changes of NSCs and their derived supporting factors.This study explores the change of NSCs and gene expression of stem cell-derived neural stem/progenitor cell supporting factor(SDNSF)in the injured spinal cord tissues of rats,and investigates the relation between the NSCs and expressions of SDNSF. METHODS:The experiment was carried out in the laboratory of Nantong University Neuroscience Institute between September 2005 and March 2006.①A total of 27 SD rats,cleaning grade,were offered by the Animal Experimental Center of Nantong University.Twelve rats used for immunohistochemistry assay were divided into sham operation group and spinal cord injury group,while other 15 rats used for RT-PCR detection were assigned into sham operation group and spinal cord injury group.All the disposals were in agreement with the ethical standard for animals.②The spinal cord contusion model of rats was established according to Allen's falling strike method.Laminectomy was conducted without strike in the sham operation group.The quantity and morphology of NSCs,gila cells and SDNSF-positive cells were observed by immunochemistry to detect expressions of nestin,glial fibrillary acidic protein(GFAP)and SDNSF in the injured spinal cord on days 8 and 16 after injury.The expression of SDNSF mRNA in the injured spinal cord was studied by semi-quantitative RT-PCR on days 4,8,12,16 after injury. RESULTS:①There were nestin-positive cells about central canal of spinal cord in the sham operation group.The nestin-positive cells showed erupted roots,migrated peripherally and proliferation,some GFAP-positive cells emerged and the SDNSF-positive cells were observed,which were similar to neuron on morphology on day 8 after injury.The quantity of nestin-positive cells decreased obviously,there were a number of GFAP-pesitive cells and few SDNSF-positive cells were showed on day 16 after injury.②RT-PCR revealed that SDNSF mRNA expressed in normal rate,and the expression was up-regulated on day 4 after injury,peaked on day 8,and decreased to the normal level on day 16. CONCLUSION:①There are some NSCs about the central canal of spinal cord,which proliferate and soon may differentiate to gila cell after injury in normal rats.②SDNSF is expressed in the normal spinal cord.The expression of SDNSF mRNA in the spinal cord varies with injured time,accompanying the proliferation and differentiation of NSCs. There are intimate relations between NSCs and expression of SDNSF in the repair of spinal cord injury.

Background:14 C-urea breath test(14 C-UBT)is widely used for diagnosis of Helicobacter pylori(Hp)infection owing to its noninvasiveness and high sensitivity and specificity. Nevertheless,the presence of false-negative result can influence the diagnostic accuracy. Aims:To investigate the possible causes of false-negative 14 C-UBT for improving the accuracy of diagnosis. Methods:Eight-two cases with confirmed false-negative 14 C-UBT and 813 controls with true-positive 14 C-UBT at the People’s Hospital of Xinjiang Uygur Autonomous Region from Jan. 2014 to Aug. 2014 were enrolled. Patients in both groups were diagnosed as positive for Hp infection by Warthin-Starry silver staining combined with Hp stool antigen test. Univariate and multivariate analysis were performed to screen the factors related with false-negative 14 C-UBT. Results:In univariate analysis,5 variables were significantly different between case group and control group(P ﹤ 0. 05),and were taken into the multivariate analysis. Logistic stepwise regression analysis revealed that bile reflux( OR = 3. 961,P ﹤0. 001),post subtotal gastrectomy(OR = 9. 734,P ﹤ 0. 001),type Ⅱ Hp infection(OR = 1. 892,P = 0. 012)and upper gastrointestinal bleeding( OR = 4. 979,P ﹤ 0. 001 ) were the independent risk factors for false-negative 14 C-UBT. Conclusions:Bile reflux,upper gastrointestinal bleeding,post subtotal gastrectomy and type Ⅱ Hp infection might be the influential factors for false-negative 14 C-UBT. Combined tests for Hp infection should be suggested in patients with negative 14 C-UBT who had undergone subtotal gastrectomy or complicated with bile reflux or upper gastrointestinal bleeding.

Objective To study the effect of hydroxychloroquine (HCQ) on the suppressors of cytokine signaling (SOCS) in the kidney of MRL/lpr mice and evaluate the protection of HCQ on lupus nephritis.Methods Twenty-six rats were randomly divided into 3 groups:the control group which was consisted of 6 mice; the MRL/lpr group which was consisted of 10 mice; and the HCQ group which was consisted of 10.24-hour urinary protein level and anti dsDNA levels were tested.The expressions of SOCS-1 and SOCS-3 protein were determined by western blot.Analysis of variance was used to determine statistically significant differences between the two groups.A P value less than 0.05 was considered to be statistically significant.Results Compared with the control group,the levels of 24-hour urinary protein [(2 356.6±509.3) mg vs (440.3±90.1)mg] and anti ds-DNA (128.7±32.3 vs 14.9±1.4) were significantly increased in the MRL/lpr group,the expression levels of SOCS-1 and SOCS-3 protein were increased.After treated with HCQ,the levels of 24-hour urinary protein [(70.8±11.1) mg vs (2 356.6±509.3) mg] and anti-dsDNA (111.8±330.1 vs 128.7±32.3)were significantly decreased,the expression level of SOCS-1 and SOCS-3 protein decreased significantly (P＜ 0.05).Conclusion HCQ can inhibit SOCS expression in the kidney of lupus mice,reduce proteinuria and delay progression of immune disorders and lupus nephritis.
