Chinese Journal of Biochemical Pharmaceutics 2015;(6):71-73
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.
6.Investigation on Causes of False-negative 14 C-Urea Breath Test
Chinese Journal of Gastroenterology 2015;(3):151-154
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.
7.Use of Gastroesophageal Reflux Disease Questionnaire in Diagnosis of Gastroesophageal Reflux Disease
Chinese Journal of Gastroenterology 2015;(7):439-441
Gastroesophageal reflux disease(GERD)is a commonly seen digestive disease. So far,there is no golden standard for the diagnosis of GERD. The main diagnosis methods used in clinical practice include gastroscopy,24 h esophageal pH monitoring and proton pump inhibitor test,however,these methods are either invasive or complex in procedure and with low diagnostic accuracy rate. Gastroesophageal reflux disease questionnaire(GerdQ)possesses multiple advantages such as simple,non-invasive and easily acceptable. This article reviewed the use of GerdQ in diagnosis of GERD.
8.Effect of hydroxychloroquine on the expression of suppressors of cytokine signaling in MRL/lpr mice kidney
Chinese Journal of Rheumatology 2014;18(11):773-776
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.
