Research progress of autoimmune gastritis / 中国医师杂志

Autoimmune gastritis(AIG) is a CD4 + T cell-mediated organ specific autoimmune disease of the stomach, characterized by the inherent gland atrophy in the stomach and intestinal metaplasia and/or pseudopyloric gland metaplasia. The diversity and nonspecificity of clinical features make the diagnosis difficult. In the past, AIG was thought to occur in the West, but in recent years, more and more studies have shown that the prevalence rate of AIG in China is not low. However, the disease has not attracted the attention of domestic clinical workers. Therefore, this paper reviews the latest research progress in the etiology, clinical characteristics, relationship with other diseases, diagnosis and treatment of AIG, so as to improve the understanding of clinical workers and improve the treatment rate and prognosis of AIG.

Factors associated with failure of eradication / 中南大学学报(医学版)

() infection is closely related to chronic active gastritis, peptic ulcer, mucosa-associated lymphoid tissue (MALT) lymphoma, and gastric cancer, and is also associated with some parenteral diseases. Eradication of can significantly improve gastric mucosal inflammatory response, prevent or delay gastric mucosal atrophy, intestinal metaplasia and its development, partially reverse atrophy, and reduce the risk of gastric cancer in varying degrees. In recent years, the eradication failure rate has increased. There are many reasons for the failure of eradication. Previous studies have suggested that resistance to antibiotics is the main cause of eradication failure, but recent studies have found that poor compliance is the main reason.

The patient was diagnosed as congenital adrenal hyperplasia because he was born with gonadal dysplasia and there were manifestations of salt losing and pigment changing, combined with high level of plasma ACTH. Further genetic screening revealed CYP11A1p.A359V heterozygous mutations in patients with a final diagnosis of cholesterol side chain enzyme deficiency which was treated effectively to glucocorticoid.

Value of detection of preoperative urinary soluble Fas expression in predicting the recurrence of non-muscle invasive bladder cancer / 中南大学学报(医学版)

OBJECTIVE@#To investigate the clinical value of detection of preoperative urinary soluble Fas (sFas) expression in predicting the recurrence of non-muscle invasive bladder cancer (NMIBC).
@*METHODS@#We performed a prospective research, which included 128 cases with NMIBC from January 2008 to April 2011. Expression levels of sFas in urine, which was saved at the first morning from preoperative NMIBC patients, were analyzed by ELISA. Clinical and pathological data, European Organization for Research and Treatment of Cancer (EORTC) risk group category, follow-up data and urinary sFas values were collected from each patient, and each prognostic outcome was evaluated by statistical analysis of non-parametric test. Urinary sFas values and recurrence-free probabilities were estimated by the Kaplan-Meier method and compared by the log rank test. Cox proportional hazards regression models were performed to determine the independent predictors of NMIBC recurrence. The prognosis index (PI) was established.
@*RESULTS@#The urinary sFas level was significantly elevated in the NMIBC cases with a higher stage or grade or high-risk EORTC group category than in those with a lower stage or grade or low-risk EORTC group category (each P0.05). Kaplan-Meier analysis revealed a significant increase in incidence of recurrence in the NMIBC patients with high sFas levels in the urine (P<0.001). According to Cox regression analysis, the urinary sFas level and EORTC risk group category (each P<0.05) were the independent predictors of NMIBC recurrence. Based on the outcome of Cox regression, the formula of PI=(0.004×sFas value+1.179×EORTC score) was established.
@*CONCLUSION@#Our study indicates that urinary sFas test may help to identify NMIBC patients at risk of tumor recurrence and it deserves further research.

Progress in the treatment of Helicobacter pylori infection / 中南大学学报(医学版)

Helicobacter pylori (H. pylori) infection is highly associated with the occurrence of gastrointestinal diseases, including gastric inflammation, peptic ulcer, gastric mucosa-associated lymphoid-tissue lymphoma and gastric cancer. It is a key strategy to prevent and treat these diseases by eradicating H. pylori. Due to the increasing rates of antimicrobial resistance of clarithromycin and metronidazole, the eradication rate of standard triple therapy is less than 80% in recent years. On the basis of traditional triple therapy, combination with some treatments, such as probiotics, mucoprotective agents, Chinese medicine and oral clean, can improve the H. pylori eradication rate.

Effect of interferon-α on rat liver fibrosis induced by CCl(4) / 中南大学学报(医学版)

OBJECTIVE@#To explore the curative effect and the underlying mechanism of interferon-α (IFN-α) on rat liver fibrosis induced by CCl(4).@*METHODS@#Forty-five Wistar male rats were randomly divided into 3 groups: a normal control group (n=15), a liver fibrosis group (n=15) and a IFN-α treatment group (n=15). The rats of the control group and the liver fibrosis group received peanut oil (0.2 mL/100 g body weight), twice a week for 8 weeks. The rats of the liver fibrosis group and the IFN-α treatment group were received intraperitoneal injection of 50% CCl(4) (CCl(4):peanut oil=1:1, 0.2 mL/100 g body weight, ip) or IFN-α (CCl(4):peanut oil=1:1, 0.2 mL/100 g body weight, ip), twice a week for 8 weeks. In the 9th week, the rats of IFN-α treatment group were switch to receive IFN-α at 100 000 units (s.c.) per day for 3 weeks. The rats were all sacrificed in the 11th week. Pathological changes of liver, semi-quantitative scoring of rat liver was observed. Tissue hydroxyproline, the mRNA expression of Collagen I, Collagen III, transforming growth factor-beta 1 (TGF-β1), connective tissue growth factor (CTGF), a-smooth muscle actin (α-SMA), matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of metalloproteinase-1 (TIMP-1) of rat liver was detected. The protein expression of MMP-9 and TIMP-1 also was detected.@*RESULTS@#Semi-quantitative scoring of inflammation,semi-quantitative scoring of liver fibrosis, hydroxyproline and collagen in the IFN-α treatment group were significantly lower than those in the liver fibrosis group (all P<0.05). The mRNA expression of TGF-β1, CTGF, α-SMA and TIMP-1, and the protein expression of TIMP-1 in the IFN-α treatment group were significantly lower than those in the liver fibrosis group (all P<0.05). But there was no significant difference in MMP-9 between the IFN-α treatment group and the liver fibrosis group.@*CONCLUSION@#IFN-α can decrease the liver fibrogenesis induced by CCl(4) in rats and reduce liver inflammation response. The anti-fibrosis effect of IFN-α may be related to decrease in TGF-β1, CTGF and TIMP-1 expression and to inhibiting of the hepatic satellite cells' activation and extracellular matrix synthesis.
