Objective To clarify the role of hypothalamic IL-6 in gastric mucosal blood flow, gastric juice pH value and gastric mucosal injury. Method Model of gastric stress ulcer was established by fluid percussion to make craniocerebral trauma. Twenty male SD rats fed for one week in the experiment room were randomly(random number) divided into control group, one hour group, six hours group and 12 hours group after injury. The levels and distribution of IL-6 in hypothalamus were detected by using immunohistochemistry and Western blot. Simultaneously, gastric pH value, gastric mucosal blood flow and gastric mucosal injury index of rats in each group were measured, and the histology of gastric mucosa was observed. Results IL-6 immunoreactive cells were widely distributed in neuronal cells of hypothalamus of the stressed rats especially in the para-ventricular nucleus (PVN).One hour after injury, the pH value rapidly declined, and the lowest point appeared 6 hours later. One hour after injury, the injury of gastric mucosa was found, and the injury became worse and worse as time got longer and longer. The ulcer index (UI) was increased. One hour after injury, there was a brief increase in blood flow to the peak in gastric mucosa, and then the blood flow declined until 6 hours elapsed and got stable. The experiment prompted the gastric stress ulcer appeared. Conclusions In the SD rats with gastric stress ulcer induced by craniocerebral injury incurred by hydraulic percussion, the hypothalamic IL-6 may activate neuronendocrine metabolism mediated through the activation of PVN, inducing gastric mucosal injury.

Objective To compare the impact on the results tested with arterial blood gas analysis and peripheral blood with glucose meter for critical patients in ICU in different temperature states. Methods The samples of venous biochemical test, blood arterial blood gas analysis and peripheral blood of 196 cases of critical patients in ICU were collected synchronously, and measure the D-value, correlation and bias adjustment factor of glucose blood tested with a synchronous fasting blood glucose test and venous/biochemical analyzer in different temperature states and different blood glucose groups, and the results of blood glucose test were analyzed. Results In normal temperature state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 3.31%(5/151), while the pairwise comparison showed there was both statistical signifcance between hypoglycemia group and target group (χ2=38.469), hyperglycemia group and target group (χ2=15.504) when choosing a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). In high temperatures state, hypoglycemia simultaneous rapid intravenous glucose monitoring blood glucose level results compared with the lowest positive rate 0. There was both statistical significance between hypoglycemia group and target group (χ2=18.187), hypoglycemia group and hyperglycemia group (χ2=12.857) when choose a synchronous fasting blood glucose test and intravenous blood glucose test (P<0.01). Conclusions In high temperatures state, a synchronous fasting blood glucose test can not reflect the true value of blood glucose for critical patients.

Dao-di Herbs is specificity and locality, and its unique phenotypic features is closely related to the growth and development of medicinal plants. In addition to traditional genetic, epigenetic play an important role in formation of Dao-di herbs. This paper introduces the concept of epigenetic and the role of DNA methylation in the gene expression regulation. We further prospects epigenetic mechanism in study of Dao-di herbs formation from specific phenotype and regional analysis. And study on the relationship of epigenetic and Dao-di herbs will provide a basis for quality assessment and identification of Chinese drugs.

Human bocavirus (HBoV) 1-4 have been detected both in respiratory and stool samples since the first HBoV was discovered in 2005. HBoV-1 is mostly associated with respiratory infection, while HBoV 2-4 are usually associated with intestinal tract infection. A variety of signs and symptoms have been described in patients with HBoV infection, including cough, wheezing, pneumonia, and diarrhea, but the research on pathogenic mechanism of HBoV is limited because HBoV cannot be cultured in vitro due to the lack of appropriate host cells. Three-dimensional epithelial cell culture, reverse genetics, and viral metagenomics are identified as novel tools that may promote the research on pathogenic mechanism of HBoV and the discovery of new viruses. This review summaries currently available diagnostic approaches such as electron microscopy, cell culture, PCR, and immunoassay in order to provide a method reference for indepth research on HBoV.

In the research field of quality control in Chinese medicinal materials, variation in active ingredients of medicinal plant is always the key and hot issues. With the development of high-throughput sequencing technologies and reducing cost, a large numbers of genes from medicinal plant were cloning and provide a solid foundation for further research of gene structure and its biological function, and also provides conditions for explore active ingredient variation and its quality control from the perspective of molecular pharmacognosy. This paper introduces the concept of homologous gene, gene duplication and classification. We prospect the function of duplicated genes in the role of molecular mechanism research about variation in active ingredients, aiming at providing a new way for medicinal materials quality control.

BACKGROUND: Extracorporeal shock wave therapy is indicated as an effective method for treatment of delayed fracture healing or nonunion. Osteoblasts plays an important role in this process.OBJECTIVE: To investigate the function of osteoblasts in the process of extracorporeal shock wave promoting fractures healing, and to provide theoretical support for improving shock wave therapy on fracture healing.METHODS: Primary cultured ostsoblasts were isolated from newbon SD rat calvaria and randomly divided into two groups, shock wave and control. Treated by different energies of extracorporeal shock wave, cells were incubated onto 96-well culture plate. An optimal dose of extracorporeai shock wave was selected according to survival and proliferation of osteoblasts. The osteoblasts treated by optimal energy of extracorporeal shock wave were cultured and harvested for the analysis of alkaline phosphatase by calcium cobolt stain, cell survival by CCK-8 Kit, alkaline phosphatase expression by AKP kit, mineralized nodules by Alizarin red staining, integrin β1 and β1 mRNA expressions by flow cytometry and RT-PCR, cell migration by wound healing assay.RESULTS AND CONCLUSION: The optimal energy of extracorporeal shock wave treating primary cultured osteoblasts was 10 kV (500 impulses). Following extracorporeal shock wave therapy, the cell proliferation, alkaline phosphatase activity, cell mineralization, rates of cell adhesion, as well as β1 integrin and its mRNA expressions were increased as compared with those in control group (P ＜ 0.01). Further distance of cell migration was found in extracorporeal shock wave group (P ＜ 0.05). The results showed that the optimal energy of extracorporeal shock wave could promote the proliferation, differentiation, adhesion and migration of osteoblasts in vitro, and β1 integrin may play an important role in the process of cell adhesion and migration.

Aim To investigate the protective effects of polysaccharides from the rhizomorph of Armillaria mella(AMP-1) on alloxan injured INS-1 cells.Methods Graded concentrations of AMP-1(2,10,50,100,500,1 000 mg?L-1) were added into the culture medium of alloxan injured INS-1 cells.The survival rate was measured by MTT assay.The amount of glucose-stimulated insulin secretion in different concentrations of AMP-1 was determined by radioimmunoassay(RIA).SOD and NOS activity,NO,MDA and GSH production were assayed colorimetrically.Results AMP-1 could reduce oxidative injuries induced by alloxan in INS-1 cells.The survival rate of cells treated with AMP-1 increased significantly.In the presence of 5.6 mmol?L-1 or 16.7 mmol?L-1 glucose,AMP-1(50,100,500,1 000 mg?L-1)increased glucose-induced insulin secretion in INS-1 cells in a dose-dependent manner.NOS levels and the production of NO and MDA decreased significantly by AMP-1,while SOD levels and the production of GSH increased.Conclusions AMP-1 promoted glucose-induced insulin secretion in INS-1 cells by increasing the abilities of scavenging the free radicals induced by alloxan.
