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.

Objective To evaluate the safety and efficacy of polymethylmethacrylate/PMMA (Artecoll) as an injectable dermal filler after using laser, radiofrequency and intensive pulse light. Methods In vitro, factional photothermolysis (Affirm) was directly used on the PMMA to see if there was any change in the structure or surface smoothness. In vivo, pig and guinea pig were used as the short-term and long-term models, respectively, for Artecoll. The dermal filler was first injected and then laser treatments conducted.The skin sample was observed through light microscope, scanning electronic microscope and transmission electronic microscope to see whether there were any structural changes, infiltration of inflammatory cells and the regeneration of collagen. Results Through the microscopic observation of in vitro experiment and the animal models, no distortion or rupture of the microsphere were found after the laser treatment. No uneven surface was found in the PMMA microsphere either. The microshpere was surrounded by the inflammatory cells. The infiltration was mild to intermediate with few foreign body giant cells even after several treatments of laser. There was no macrophage seen. But the collagen regeneration was distinguishable after the laser treatment. No obvious structural change was found eventually. Conclusion Artecoll is a safe and effective permanent injectable dermal filler for wrinkle reduction and contour refining.

OBJECTIVETo investigate the leukogenic function of Shuanghuang Shengbai (SHSB) granule and the related mechanisms.

METHODMouse leukopenic models were induced by radiation. Mice were divided into normal control group, model control group, positive control group-Li kejun tablet group and three different dose (high, middle, low-dose) groups of SHSB granule. The peripheral hemogram, thymus index (TI), spleen index (SI), bone marrow nucleated cell (BMNC) and colony forming unit-spleen (CFU-S) were evaluated. The proliferation of bone marrow cells was determined. The in vitro cultured colony forming unit granulocyte macrophage (CFU-GM) was estimated. The index of CD34+ cell in BMNC were determined by flow cytometry. The ultra-micro structure of bone marrow were observed by electromicroscope.

RESULT(1)SHSB rranule could increase the WBC of model mice; (2)SHSB granule could increase BMNC and promote the proliferation of bone marrow cell; (3)SHSB granule could increase CFU-S, CFU-GM and CD34+ cell index in BMNC of model mice significantly; (4)SHSB Granule could also protect the bone marrow hemotopoietic microenvironment from the harm of radiation; (5)SHSB granule could increase the SI of model mice, indicating the enhancement of immunological function.

CONCLUSIONSHSB granule has apparent leukogenic function. The mechanism may be related to enhancing the proliferation of hematopoietic cells and protecting the bone marrow hemotopoietic microenvironment.
