Objective To investigate the prevalence and related factors of peptic ulcer (PU) and Helicobacter pylori (Hp) infection in military men. Methods A stratified multi-stage cluster randomly sampling method was used. A questionary survey was conducted in 6 160 soldiers garrisoned at south China, inclding: PU symptoms and risk factors questionnaires; gastroscopy and Hp detection. Results Incidence of PU correlative symptoms (Sc≥5) in soldiers was 18.60%. The prevalence of PU was 12.78%.Higher incidence of PU was found among the soldiers who enlisted for less than 1 year, or were from south China, or served in armored troops. The prevalence of Hp infection was 62.67%. Hp infection (OR4.60), smoking (OR3.8), sustained intense training (OR4.3), fighting vehicle driving (OR6.0) and frequent mental intension (OR3.7) seemed to be the main risk factors of PU. While hot food, milk and whether or not the only child in a family showed no relation with PU incidence. Conclusion Higher prevalence of PU and Hp infection existed in service men. For soldiers, PU incidence is closely associated with Hp infection, military training, mental factors, and also related to soldiers′ enlisted period, arm of the service and the region where the soldiers come from.

Objective To research pacemaker cells outside conductive system of rat and mouse heart. Methods Paraffin and frozen serial sections (stained with HE, Masson, cholinesterase technique), and ultrastructural sections, from atrial tissue of 10 rats and 15 mice were observed by light and electron microscopy to find latent pacemaker-like cells. Results Some round or elliptical cells were scattered and irregularly detected in right and left atrial tissue of rat and mouse. Their nuclei were larger, plasma was clearer and cellular organelles were fewer than those of working myocyte. These cells were similar to pacemaker cells in sinoatrial node.Conclusion There are some pacemaker-like cells in right and left atrial tissue of rat and mouse. The finding can provide a morphological basis for ectopic beat of atrium.

The salivary glands were exposed and isolated from the larvae of Simulium quinquestriatum and stained in carbol fuchsin, squashed between slide and coverslide. Slides were examined and photographed under microscope to measure the polytene chromosomes. Systematic analysis was made. Results indicated that the number of the polytene chromosomes of both isolates is three. The main characteristic chromosomal structures are homologized. Only the banding types of ⅡL are different.

Replacement therapy is the most effective method for the treatment of end-stage liver disease,and decellularized liver bioscaffold broadens the research field of the replacement therapy.The present liver bioscaffold preparation is to perfuse chemical reagents (detergents,enzymes,et al) into the vascular structure of the liver under certain physical conditions,so as to remove cellular components and retain extracellular matrix and microvascular structure.Cells were reseeded into the decellularized liver scaffold to obtain the recellularized liver,which can be cultured and evaluated in vitro or in vivo by observing the adhesion of seeded cells,detecting the synthesis and secretion of the recellularized liver.Currently,the selection of seed cells,recellularization protocol and recellularized liver transplantation are still under exploration.In this review,the preparation,evaluation,detection and application of the decellularized liver bioscaffold are introduced for the further experimental study and clinical research.

Objective To analysis the clinical features of elderly diffuse large B-cell lymphoma (DLBCL) patients with Epstein-Barr virus (EBV) infection and their prognostic factors.Methods 250 cases of DLBCL were retrospectively studied by in situ hybridization (ISH) to detect the EBV and by immunohistochemical to evaluate the histological type and Ki-67 protein.Results 36 cases with EBVpositive included 28 elderly (aged ≥ 60 years), of which 21 cases were Han, 15 cases were Uygur, male/ female ratio was 2 : 1.There were 23 cases with nodal presentation only, 13 cases with extra-nodal presentation.Twenty-nine patients presented with advanced disease (Ann Arbor stage Ⅲ/Ⅳ), 30 patients were found with high lactate dehydrogenase (LDH), 22 patients with high IPI score (3-5).Histological observation showed a diffuse and polymorphic proliferation of large lymphoid cells with varying degrees of reactive components.These tumor cells were frequently characterized by a broad range of B-cell maturation, containingcentroblasts, immunoblasts, and Hodgkin-and Reed-Stemberg (HRS)-like giant cells.Immunohistochemical studies showed that tumor cells were positive for CD20 and (or) CD79a in almost cases, most of the cases had a high proliferative index.CD10, bcl-6, Mum-1 performed histological type, 31 cases were non-germinal center.Except the age and location (P ＜ 0.05), no other significant differences were observed in Han and Uygur elderly EBV+ DLBCL (P ＞ 0.05).Conclusion The incidence of elderly EBV+ DLBCL is low, it has some unique clinical and pathological features with poor prognosis.

Object To investigate the saccharide changes of Radix Rehmanniae when being processed. Methods The fresh roots were torrefied at 65 ℃ and sampled at 0,1, and 6 d. The samples and 4 h steamed slices of those dried roots were extracted with hot water respectively. The extracts were subjected to HPLC analysis, Sugar pak 1 column at 80 ℃,with water as the mobile phase at 0 7 mL/min and detected by RID. Results There are three principal components in the fresh roots, i.e. stachyose (11%-15%), sucrose (0 30%-0 92%), and catalpol (0 27%-0 88%). In the processing of the fresh roots, the HPLC chromatorams of the extracts differed to each other remarkbly. On the chromatogram of roots torrefied for 1 d, one distinct monosaccharide peak displayed at 10 2 min, which is likely to be galactose, and it become prominent in the dried roots together with raffinose. In steamed ones, the peaks of fructose and glucose became outstanding. Conclusion According to the HPLC chromatograms, the degalacto sylation of stachyose may take place during torrifying, while defructosylation during steaming. One of the principal purposes of the processing may be for stachyose degradation for its flatulence causing character.
