Nuclear Science and Techniques 2006年第3期17卷 185-192页

作者： WU Ge-ping QIU sui-Zheng SU Guang-Hui JIA Dou-Nan State Key Laboratory of Multiphase Flow in Power Engineering Xi＇an Jiaotong University Xi＇ an 710049 China

Because of the practical importance of two-phase instabilities, substantial efforts have been made to date to understand the physical phenomena governing such instabilities and to develop computational tools to model the dynamics. The purpose of this study is to present a numerical model for the analysis of flow-induced instabilities in forced-convection steam generator. The model is based on the assumption of homogeneous two-phase flow and ther- modynamic equilibrium of the phases. The thermal capacity of the heater wall has been included in the analysis. The model is used to analyze the flow instabilities in the steam generator and to study the effects of system pressure, mass flux, inlet temperature and inlet/outlet restriction, gap size, the ratio of do / di, and the ratio of qi / qo on the system be- havior.

Chinese Chemical Letters 2007年第3期18卷 345-348页

作者： Yi Ming Liu sui ping Deng Hui Zheng Jian Ming Ouyang Department of Chemistry and Chemical Engineering Hunan Institute of Science and Technology Yueyang 414000 China lnstitute of Biomineralization and Lithiasis Research Jinan University Guangzhou 510632 China

The ring patterns of calcium oxalate crystals were induced by domains in Langmuir-Blodgett （LB） films of dipalmitoylpho- sphatidylcboline （DPPC）. The result was explained by the defects at the ring boundaries of liquid condensed （LC） and liquid expanded （LE） phases of LB film. These boundaries could provide less free energy and much more nucleating sites for COM crystals.

The influence of sulfated polysaccharide （SPS） isolated from marine algae Sargassum fusiforme on the morphology and phase compositions of urinary crystal calcium oxalate was investigated in vitro by means of scanning electron microscopy and X-ray diffraction. SPS maybe is a potential inhibitor to CaOxa urinary stones by inhibiting the growth of calcium oxalate monohydrate （COM）, preventing the aggregation of COM, and inducing the formation of calcium oxalate dihydrate （COD） crystals.

ULCERATIVE colitis is a chronic inflammatorydisease characterized by diffuse mucosalinflammation involving the rectum and extendingproximally to involve all or part of the colon. Astep-up approach for medical therapy is routinely applied,from 5-aminosalicylic acid （ASA） compounds, corticosteroids,immunomodulators, and biologics.1 Thrombosis, mainlyvenous, is a rare and well-recognized extra-intestinalmanifestation of inflammatory bowel disease.2 In thisarticle, we report the use of thrombolytic and antithrombotictherapy for the venous thrombosis in a 55-year-old malepatient with refractory and active ulcerative colitis withexcellent outcome.

The inducing effect of potassium citrate （K3cit） on simultaneous growth of calcium oxalate mono-（COM）, di-（COD）, and trihydrate （COT） crystals in synthetic urine was observed with double diffusion gelatinous technique. K3cit can induce the formation of COD and COT, inhibit the aggregation and decrease the surface area of COM crystals. It supported the clinical use of K3cit and may provide important clues to this disease in cure and in search for new drugs.

Hydrolysis of olive oil catalyzed by Candida lipolytica lipase was investigated. The relative concentration of the components in the product was determined by using high performance liquid chromatography（HPLC）. Furthermore, a novel rapid method to detect the hydrolytic process of olive oil was developed based on the relationship between the acid value and the relative concentration of the different components.

Effect of the ginsenoside Rb1 on the spontaneous contraction of intestinal smooth muscle in mice

引用

World Journal of Gastroenterology 2012年第38期18卷 5462-5469页

作者： Lei Xu sui-ping Huang Scientific Research Station for Post-doctoral Studies Post-doctoral Research Centre Zhongshan Affiliated HospitalGuangzhou University of Traditional Chinese Medicine Zhong-shah 528400 Guangdong Province China Department of Gastroenterology GuangdongProvincial Traditional Chinese Medicine Hospital Ersha IslandBranch Guangzhou 510405 Guangdong Province China

AIM: To investigate the effect and the possible mechanism of ginsenoside Rb1 on small intestinal smooth muscle motility in mice. METHODS: Intestinal smooth muscle strips were isolated from male ICR mice (5 wk old), and the effect of ginsenoside Rb1 on spontaneous contraction was recorded with an electrophysiolograph. The effect of ginsenoside Rb1 on ion channel currents, including the voltage-gated K + channel current (IK V ), calcium-activated potassium channel currents (IK Ca ), spontaneous transient outward currents and ATP-sensitive potassium channel current (IK ATP ), was recorded on freshly isolated single cells using the whole-cell patch clamp technique. RESULTS: Ginsenoside Rb1 dose-dependently inhibited the spontaneous contraction of intestinal smooth muscle by 21.15% ± 3.31%, 42.03% ± 8.23% and 67.23% ± 5.63% at concentrations of 25 μmol/L, 50 μmol/L and 100 μmol/L, respectively (n=5,P<0.05). The inhibitory effect of ginsenoside Rb1 on spontaneous contraction was significantly but incompletely blocked by 10 mmol/L tetraethylammonium or 0.5 mmol/L 4-aminopyridine, respectively (n=5, P<0.05). However, the inhibitory effect of ginsenoside Rb1 on spontaneous contraction was not affected by 10 μmol/L glibenclamide or 0.4 μmol/L tetrodotoxin. At the cell level, ginsenoside Rb1 increased outward potassium currents, and IK V was enhanced from 1137.71 ± 171.62 pA to 1449.73 ± 162.39 pA by 50 μmol/L Rb1 at +60 mV (n=6, P<0.05). Ginsenoside Rb1 increased IK Ca and enhanced the amplitudes of spontaneous transient outward currents from 582.77 ± 179.09 mV to 788.12 ± 278.34 mV (n=5, P<0.05). However, ginsenoside Rb1 (50 μmol/L) had no significant effect on IK ATP (n=3, P<0.05). CONCLUSION: These results suggest that ginsenoside Rb1 has an inhibitory effect on the spontaneous contraction of mouse intestinal smooth muscle mediated by the activation of IK V and IK Ca , but the K ATP channel was not involved in this effect.
