Objective To observe the clinical efficacy and safety of re-bamipide combined with rabeprazole sodium enteric -coated tablets in the treatment of chronic atrophic gastritis .Methods A total of 94 pa-tients with chronic atrophic gastritis were randomly divided into control and treatment groups with 47 cases per group.Control group was given riberazole 20 mg per time, qd, orally.Treatment group received rabe-prazole 0.1 g per time, tid, orally, on the basis of control group.Two groups were treated for 8 weeks. The clinical efficacy, pepsinogen (PG), endothelin (ET) and adverse drug reactions were compared be-tween two groups.Results After treatment, total effective rates of treat-ment and control groups were 93.62%( 44 cases/47 cases ) and 70.21%(33 cases/47 cases) with significant difference ( P<0.05 ) . After treatment, the main indexes of treatment and control groups were compared: PGⅠ were ( 127.38 ±13.96 ) and ( 103.84 ±13.58 ) μg· L-1, ET were (65.49 ±5.99 ) and ( 74.20 ±9.79 ) ng· L-1, there were statistically significant differences (all P<0.05).The adverse drug reactions of treatment group were liver dysfunction and skin rash , which in control group were diarrhea , rash and nausea and vomiting .The total incidence of adverse drug reactions were 6.38%and 14.89%without significant difference (P>0.05).Conclusion Rebamipide combined with rabeprazole sodium enteric-coated tablets has a definitive clinical efficacy in the treatment of chronic atrophic gastritis , which can effectively regulate the levels of PG and inhibit the expression of ET , without increasing the incidence of adverse drug reactions.

OBJECTIVETo investigate the influence of hepatitis B virus (HBV)-encoded small surface protein (SHBs) on hepatic cell expression of host genes related to lipid metabolism.

METHODSThe full-length SHBs gene was amplified from HBV genotype C by polymerase chain reaction (PCR) and cloned into the pcDNA3.1(+) expression vector for stable transfection into HepG2 cells (selected by G418 screening); cells transfected with empty vector served as control. The SHBs mRNA and protein levels were detected by reverse transcription-PCR and enzyme-linked immunosorbent assay. SHBs effects on expression of genes and proteins related to lipid metabolism were detected by real-time quantitative (q)PCR and western blotting, respectively.

RESULTSThe stably transfected cell line HepG2-pn3.1-SHBs was established successfully. qPCR showed that the HepG2-pn3.1-SHBs cells had significantly down-regulated transcription of the ECHS1, APOA1 and LPL genes (0.161+/-0.043 vs. control cells: 0.210+/-0.022, t = 2.479; 0.031+/-0.007 vs. 0.094+/-0.055, t = 2.752; 0.770+/-0.036 vs. 0.982+/-0.031, t = 10.914), but significantly up-regulated ACC and SREBP-1c genes (0.113+/-0.027 vs. 0.059+/-0.022, t = -3.757; 0.019+/-0.002 vs. 0.015+/-0.001, t = -4.330). The CPT1a and PPARa genes' expression was slightly, but not significantly, down-regulated in the HepG2-pn3.1-SHBs cells (0.028+/-0.005 vs. 0.030+/-0.004, t = 1.022; 0.014+/-0.004 vs. 0.015+/-0.002, t = 0.758). Western blotting showed similar expression trends for the corresponding proteins.

CONCLUSIONSHBs alters the expression of some host genes with known functions in fatty acid synthesis and decomposition; however, it remains unclear whether the hepatitis B surface antigen can directly contribute to development of hepatic steatosis.

OBJECTIVETo study the clinicopathologic features of various types of mature T-cell and natural killer (NK)/T-cell lymphoma in Guangdong, China, with respect to the 2008 WHO classification of lymphoid neoplasms.

METHODSEleven hundred and thirty-seven (1137) cases of mature T-cell or NK/T-cell lymphoma diagnosed during the period from 2002 to 2006 in Guangzhou area were retrieved. The clinical data, histologic features and immunohistochemical findings were reviewed by a panel of experienced hematopathologists. Additional immunostaining was performed if indicated. The cases were re-classified according to the 2008 WHO classification of lymphoid neoplasms.

RESULTSNine hundred and sixty-three (963) cases fulfilled the diagnostic criteria of mature T-cell or NK/T-cell lymphoma and accounted for 20.1% of all cases of lymphoma encountered during the same period (963/4801). A predominance of extranodal involvement was noted in 644 cases (66.9%), while 319 cases (33.1%) showed mainly nodal disease. The prevalence of various lymphoma subtypes was as follows: peripheral T-cell lymphoma, unspecified (PTCL, NOS) 293 cases (30.4%), extranodal NK/T-cell lymphoma, nasal type 281 cases (29.2%), anaplastic large cell lymphoma (ALCL) 198 cases (20.6%), and angioimmunoblastic T-cell lymphoma (AILT) 46 cases (4.8%). The male-to-female ratio was 1.99. The median age of the patients was 44 years, with the peak age of PTCL, NOS, extranodal NK/T-cell lymphoma, nasal type and AILT being 55 to 64 years, 25 to 54 years and 65 to 74 years, respectively. ALK-positive ALCL occurred more frequently in young age, while the ALK-negative ALCL cases occurred mainly in the elderly.

CONCLUSIONSExtranodal lesions predominate in mature T-cell and NK/T-cell lymphomas occurring in Guangzhou area. There is a male predominance and the overall incidence shows no increasing trend with age of the patient. The peak age of various subtypes however varies. The most common subtype was PTCL, NOS, followed by extranodal NK/T-cell lymphoma, nasal type, ALCL and AILT. The relatively frequent occurrence of extranodal NK/T-cell lymphoma, nasal type in Guangdong area is likely associated with the high incidence of Epstein-Barr virus infection there.
