Background:Single-balloon enteroscopy(SBE)is a new method for the examination of small intestine,its clinical value in suspected small intestinal diseases need to be further studied. Aims:To evaluate the diagnostic and therapeutic value of SBE in suspected small intestinal diseases. Methods:A total of 73 suspected small intestinal diseases patients who had undergone 81 SBE examinations from July 2011 to October 2013 at Chengdu Military General Hospital were retrospectively examined,indications,diagnostic and therapeutic value of SBE in suspected small intestinal diseases were analyzed. Results:Of all the 81 examinations,33(40. 7% )were obscure gastrointestinal bleeding,29(35. 8% ) incomplete intestinal obstruction,and 19(23. 5% )chronic abdominal pain or diarrhea. The intubation depth was 230 cm for the oral approach,and 100 cm for the anal approach. The diagnostic yield of SBE was 67. 9% ,the main lesions were small intestinal ulcer,small intestinal inflammation,small intestinal tumor,small intestinal polyp. A total of 8 patients underwent endoscopic therapy,of whom 5 underwent endoscopic hemostatic therapy and 3 underwent resection of polyp. No serious complications were found. Conclusions:SBE is a safe and reliable diagnostic and therapeutic method for suspected small intestinal diseases,and its main indications are obscure gastrointestinal bleeding and incomplete intestinal obstruction.

Research on novel pullulanase has major significance on the domestic industrialization of pullulanase and the breakdown of foreign monopoly. A thermophilic bacteria LM 18-11 producing thermostable pullulanase was isolated from Lunma hot springs of Yunnan province. It was identified as Anoxybacillus sp. by 16S rDNA phylogenetic analysis. Full-length pullulanase gene was cloned from Anoxybacillus sp. LM18-11. The optimum temperature of the pullulanase was between 55 and 60 degrees C with a half-life as long as 48 h at 60 degrees C; and its optimum pH was between 5.6 and 6.4. V(max) and K(m) of the pullulanase was measured as 750 U/mg and 1.47 mg/mL, which is the highest specific activity reported so far. The pullulanase crystals structure showed a typical alpha-amylase family structure. The N-terminal has a special substrate binding domain. Activity and substrate binding were decreased when the domain was deleted, the V(max) and K(m) were 324 U/mg and 1.95 mg/mL, respectively. The pullulanase was highly heterologous expressed in Bacillus subtilis by P43 promoter. The extracellular enzyme activity was 42 U/mL, which increased more than 40 times compared to the initial strain. This pullulanase has good application prospects.

To establish a UPLC-MS/MS method for the simultaneous determination of geniposide, genipin 1-O-beta-D-gentiobioside and geniposidic acid in rat brains and study the brain pharmacokinetics of the three iridoid glycosides in stroke rat after the oral administration of Xingnaojing. In this experiment, brain samples were precipitated with protein for twice. Acquity BEH C18 column was adopted, with acetonitrile-0.1% formic acid-water as the mobile phase for gradient elution. ESI source was adopted for mass spectra; multiple reaction monitoring (MRM) was conducted to detect negative ions. The time for sample analysis was 3.5 min. the results showed good linear relations among the three iridoid glycosides, with the extraction recovery between 99.6% and 114.3%, good intra- and inter-day precisions and accuracies and stability in line with the requirements. The t1/2 and MRT in the three components were similar in brains of stroke rats. Geniposide and genipin 1-O-beta-D-gentiobioside showed double peaks; where as geniposidic acid showed a single peak. In conclusion, the method is so specific, sensitive, accurate and reliable that it can be used to study the brain pharmacokinetics of Xingnaojing oral preparation.

Objective: To learn the health literacy level and its influencing factors among junior high school students in Jiaxing, so as to provide basis for health promotion of adolescents. Methods: The junior high school students who had been studying and living in Jiaxing for more than six months were selected by multistage cluster random sampling method. A questionnaire survey was conducted to collect general information and health literacy level (including basic knowledge and concept, healthy lifestyle and behaviors, and basic skills) of these selected students. The multivariate logistic regression model was used to analyze the influencing factors for health literacy. Results : Of 1 773 questionnaires collected, 1 738 were valid, accounting for 98.03%. The level of health literacy in the junior high school students in Jiaxing was 22.84% ( 95%CI: 20.87%-24.82% ), The levels of basic knowledge and concept, healthy lifestyle and behaviors, and basic skills were 55.29% ( 95%CI: 52.95%-57.63% ), 21.75% ( 95%CI: 19.81%-23.69% ), 53.05% ( 95%CI: 50.70%-55.40%), respectively. Multivariate logistic regression analysis showed that the second grade and above ( OR: 1.609-1.835, 95%CI: 1.195-2.459 ), mother's educational level of technical secondary school/senior high school and above ( OR: 1.965-1.976, 95%CI: 1.276-3.357 ), and self-rated academic achievement of medium and above ( OR: 1.881-2.441, 95%CI: 1.359-3.335 ) were the promoting factors for health literacy level of junior high school students; self rated health status as unhealthy ( OR=0.254, 95%CI: 0.089-0.721 ) was an obstructive factor. Conclusions The health literacy level of the junior high school students in Jiaxing was 22.84%. The level of healthy lifestyle and behaviors was the lowest in three aspects. Grade, mother's educational level, self-rated academic performance and self-rated health status may have impacts on health literacy level of junior high school students.

Objective:To evaluate the clinical efficacy of SKy bone expander system in percutaneous kyphoplasty for treat- ment of osteoporotie verterbral compression fracture.Methods:Twenty-two patients(aged 62-90 years,32 vertebrae)under- went percutaneous kyphoplasty using SKy bone expander system.The bone cement was injected into the collapsed vertebrae. The vasual analogue scale(VAS)and complications were recorded during follow up.Results:The operations were successful in all patients via unilateral or bilateral approach.The operation time ranged from 30 to 120 min.The mean volume of cement in- jected into each vertebra body was(4.8?1.1)ml,ranged from 3.1 to 6.8 ml.Extravertebral leakage of bone cement was ob- served in two vertebrae with no symptoms.All patients had their pain relieved;the VAS was 7.6?0.8 before operation,3.5?0.5 one day after operation,2.8?0.6 one week after operation,and 2.4?0.6 one month after operation,with significant difference found between preoperation and postoperation(P

Prolyl-4-hydroxylase domain (PHDs) family is one of the most important regulatory factors in hypoxic stress. PHD2 plays a critical role in cells and tissues adaptation to the low oxygen environment. Its hydroxylation activity regulates the stability and transcriptional activity of the hypoxia-inducible factor 1 (HIF-1), which is the key factor in response to hypoxic stress. Subsequently, PHD2 acts as an important factor in oxygen homeostasis. Studies have shown that PHD2, through its regulation on HIF-1, plays an important role in the post-ischemic neovascularization. Furthermore, under hypoxic condition, PHD2 also regulates other pathways that positively regulate angiogenesis factors HIF-1 independently. Moreover, recently, several evidences have also shown that PHD2 also affects tumor growth and metastasis in a tumor microenvironment. Based on these facts, PHD2 have been considered as a potential therapeutic target both in treating ischemic diseases and tumors. Here, we review the molecular regulation mechanism of PHD2 and its physiological and pathological functions. We focus on the role of PHD2 in both therapeutic angiogenesis for ischemic disease and tumor angiogenesis, and the current progress in utilizing PHD2 as a therapeutic target.
