Objective To investigate the expression of humanβ-defensin 2 (HBD-2) in gastric mucosa of Helico-bacter pylori (H. pylori) associated gastric mucosa-associated lymphoid tissue (MALT) lymphoma, and the role of HBD-2 in gastric MALT lymphoma. Methods Forty gastric mucosa specimens from patients with H. pylori associated gastric MALT lymphoma were collected. And 36 gastric mucosa specimens from chronic superficial gastritis without H. pylori infection were included as control group. The expression of HBD-2 was detected by immunohistochemistry staining. Results The ex-pression of HBD-2 was significantly higher in H. pylori associated gastric MALT lymphoma than that of control group. (P＜0.01). The expression of HBD-2 was significantly decreased after the eradication of H. pylori (P＜0.01). The expression of HBD-2 was significantly higher in H. pylori associated gastric MALT lymphoma than that of lymphoma cells (P＜0.01). There was no expression of HBD-2 in lymphoma cells. Conclusion HBD-2 is possibly involved in the pathogenesis of H. pylori associated gastric MALT lymphoma. But whether it has anti-tumor effect is not clear.

AIM:To investigate the effect of hirsutine on hypoxia-induced migration and invasion abilities of human breast cancer MCF-7 cells and its possible mechanism. METHODS:CCK-8 assay was employed to detect the cyto-toxic effect of hirsutine on the MCF-7 cells. Cell migration was observed by wound healing assay,and cell invasion ability was measured by Transwell invasion assay. Western blot was used to analyze the protein levels of hypoxia-inducible factor-1α(HIF-1α),Snail,E-cadherin and matrix metalloproteinase-9 (MMP-9). The mRNA levels of HIF-1α was detected by RT-PCR. RESULTS:Hirsutine remarkably reduced the cell viability from 32 μmol/L(P<0.05),and the IC50value was 62.82 μmol/L. In hypoxia state,MCF-7 cells showed more powerful capabilities of migration and invasion (P<0.05), higher protein levels of HIF-1α,Snail and MMP-9 (P<0.05),lower protein level of E-cadherin(P<0.05),and higher mRNA level of HIF-1α (P<0.05). These hypoxia-induced effects were all inhibited by hirsutine at 16 μmol/L (P<0.05),apart from the mRNA level of HIF-1α. CONCLUSION:Hirsutine inhibits hypoxia-induced migration and inva-sion in human breast cancer MCF-7 cells most likely via down-regulation of the protein levels of HIF-1α,Snail and MMP-9,and up-regulation of the protein level of E-cadherin.

Objective To investigate the effect of berberine on inhibiting HT-29 human colon cancer cell proliferation induced by deoxycholic acid(DCA).Methods The berberine with concentration of 1,5,10 or 20?mol/L were added into the HT-29 human colon cancer cell culture media containing 200?mol/L DCA.The effects of berberine on cell proliferation were studied by the method of MTT.RT-PCR was applied to measure the expression of cyclooxygenase-2(COX-2)mRNA.Cellular immunochemical stain was applied to label COX- 2 protein expression.Concentration of prostaglandin E2(PGE2)was measured by radioimmunoassay. Results HT-29 cells were incubated with DCA for 6 h,COX2 expression of cells were increased prominent compared to controls(65.5%?5.6% vs.6.2%?1.1%).The level of PGE2 were increased(24.1 ng/L?1.4 ng/L vs.10.6 ng/L?0.8 ng/L).One?mol/L berberine reduced the proliferation rate of HT-29 in- duced by DCA over 6 h,the proliferation rate was 7.4?3.5%.Both COX-2 mRNA expression and the level of PGE2 were inhibited when the concentration of berberine was over 1?mol/L,and in a concentration-time dependent manner.Conclusions Berberine can inhibit the proliferation of HT-29 human colon cancer cell in- duced by DCA.Berberine can also suppress the expression of COX-2,and decrease the production of PGE2. These data provide new insights into the mechanism of its anti-cancer properties.

Objective: To establish an echocardiography parameter scoring system for assessing the risk of 1 year re-admission in patients with left ventricular systolic dysfunction (LVSD). Methods: A total of 412 chronic LVSD patients treated in our hospital from 2007-01 to 2016-01 were studied and the end point event was 1 year re-admission. The data included in 280 patients from 2007-01 to 2014-12 for establishing the scoring system and 132 patients from 2015-01 to 2016-01 for verifying the system. Based on 7 echocardiography parameters, the patients were divided into 7 sets of groups: ① Left ventricular diameter (LVD): Group0, n=290 and Group1, n=122;② Mitrial regurgitation (MR): Group0, n=203, Group1, n=138 and Group2, n=71; ③ Tricuspid regurgitation (TR): Group0, n=302, Group1, n=90 and Group2, n=20; ④ LVEF: Group0, n=272 and Group1, n=140; ⑤ Pulmonary artery systolic pressure: Group0, n=282 and Group1, n=130; ⑥ Hydropericardium: Group0, n=347 and Group1, n=65; ⑦ Hydrothorax:Group 0, n=261, Group1, n=86 and Group2, n=65. The parameters were identified by COX regression analysis, weighted value of scoring system was calculate by hazard ratio (HR), predictive value for1 year re-admission was assess by ROC curve and finally, scoring integration was verified by validation data group. Results: The integration score was calculated as follows: LVD>60mm=1 point; TR: Group1=1 point and Group2=3 points; MR: Group1=2 points and Group2=4 points; Hydrothorax: Group1=2 points and Group2=3 points;Hydropericardium=1 point. COX regression analysis indicated that for 1 year re-admission: HR=1.552 in Group1 vs Group0, HR=3.374 in Group2 vs Group0 and HR=4.562 in Group3 vs Group0, all P<0.05. The AUC of ROC for establishing the data was 70.0% (95% CI 0.640-0.761) and for verifying the data was 70.4% (95% CI 0.616-0.792); the best integration score was 4 points. Conclusion: Echocardiography parameter scoring system may better predict the risk of 1 year re-admission in LVSD patients which is superior to single echocardiography parameter.

BACKGROUNDDipeptidyl peptidase-IV (DPP-4) inhibitors are now used to improve postprandial glycemic control in type 2 diabetes. However, their effects on hepatic glucose production (HGP) in obesity are not clear. This study was designed to test the hypothesis that gluconeogenesis and HGP can be modulated by DPP-4 inhibitors in obesity.

METHODSSprague Dawley male rats were divided into four groups, each on a different diet: general rat chow, n = 10 (G); G + sitagliptin, n = 10; high fat chow (obesity), n = 10 (55% fat calories, HFO); HFO + sitagliptin, n = 10. After 10 weeks, the rats were fasted overnight and glucose metabolism was determined using 3-(3)H-glucose and (14)C-glycerol as tracers.

RESULTSGlycerol rate of appearance (P < 0.00001), plasma glycerol (P < 0.05) and free fatty acid (FFA) (P < 0.05) concentrations, and HGP (P < 0.05) were decreased in HFO + sitagliptin group compared with HFO group, but there was no significant difference between G and G + sitagliptin groups (P > 0.05). Gluconeogenesis in HFO group was five times of that in G rats (P < 0.01), but was significantly declined in HFO + sitagliptin group (P < 0.0001).

CONCLUSIONSGluconeogenesis and HGP were inhibited by sitagliptin in high fat-induced obese rats due to decreased glycerol availability, which was a result of reduced glycerol release from adipose tissues. The finding suggests that sitagliptin is potentially useful for controlling fasting glucose in obesity, thereby delaying or preventing the development of diabetes.

The International Standard Chinese-English Basic Nomenclature of Chinese medicine (ISN) was released in 2007, a nomenclature list consisting of 6 500 Chinese medical terms. ISN was the culmination of several years of collaborative diligent work of over 200 specialists who represent Chinese medicine in 68 countries. The overall goal for devising standard English nomenclature for Chinese medicine is to develop a practical international standard nomenclature for Chinese medical basic terms, to make it compatible with contemporary research and educational standards in the globalized health care service. In this article, provided is an overview of principles and methods for the multilingual translations, the processes behind the particular content of the Chinese-English ISN and an introduction to the ongoing new projects, i.e. the multilingual versions of ISN (International Standards of Chinese-Spanish, Chinese-French and Chinese-Portuguese Basic Nomenclature of Chinese Medicine).
