The influence of Gynostemma pentaphyllum extract ( G. P ) on the life span of fruit fly was observed. G. P (0.5% and 1.0%) significantly increased mean life span by 11.8% and 12.2%, respectiyely, when fed to male adults.At 0.25% concentraction, the female adults were found to yield an increase of 24.1% in mean life span and the male an increase of 18.5%.Rearing flics on 0. 5% G. P during both the developmental and adult stages proved to be even more effective than just feeding during the adult stage. The mean life span of male and female adults were increased by 53.3% and 46.1% , respectively, but at the higher concen-tration of 1.0%, the increase was 14.4% and 9.7%, respectively,G. P obviously improved the growth of larvae when given aconcentration of 0.5%,No marked change was observed in the copulatory rate of fruitflies after the treatment of 0.5% G.P.

Objective To investigate imaging features and clinical characteristics of the small coronary-bronchial artery fistula (CBF). Methods By retrospective analysis of image data from May 2007 to November 2011 for coronary angiography in 30 284 patients without chronic lung or pulmonary vascular disease patients, 13 cases of small CBF (diameter of the end of fistula near coronary artery< 2 mm) were detected. Incidence of CBF was counted, its morphology was described, and its clinical features were preliminarily analyzed and summarized. Independent sample t test and χ2 test were used to compare diameters and incidences of CBF originatng from left and right coronary arteries. Results In this study primary CBF detection rate was 0.043%(13/30 284). The ends of CBFs near coronary arteries were slender and their diameter average was (1.57 ± 0.75) mm. In this study all of the CBF were from the right coronary artery and left circumflex coronary artery, finding no cases starting from the left anterior descending coronary artery. There was no significant difference between incidence of CBFs originating from the right coronary artery and left circumflex coronary artery coronary and the diameters of CBFs. In 13 cases of CBF, 9 cases of myocardial ischemic symptoms were caused by coronary artery stenosis, which was proven by angiography;Four cases without myocardial ischemic symptoms or with very atypical symptoms were finally diagnosed as cardiac neurosis. After branching, the CBF diameters of these coronary arteries were seen no evindently reduced, which suggested that the coronary bypass had less blood flow, and therefore had no significant hemodynamic significance. Conclusions Congenital CBF can exist in populations without chronic lung or pulmonary vascular disease. The main image features are that their diametes were small and all originate from the right coronary artery and left circumflex coronary artery. The most fundamental clinical features are that there're no symptoms of myocardial ischemia due to coronary artery steal and no obviously hemodynamic significance. It is important to well recognize this type of CBF for enriching radiographic knowledge, identifying various anatomic variations, and carrying out clinical diagnosis and treatment.

Objective To study the association between cytotoxin-associated gene A of Helicobacter pylori (Hp-CagA) and the expressions of mtp53 and c-myc protein in different subtypes of intestinal metaplasia.Methods One hundred and sixty-five patients with gastroscopy included 125 cases with chronic atrophic gastritis with intestinal metaplasia,40 cases with non-atrophic gastritis.Intestinal metaplasia included complete intestinal metaplasia,incompletetype intestinal metaplasia,complete colonic epithelial metaplasia and incomplete colonic epithelial metaplasia.The carbon-14-urea breath test was used to determine Helicobacter pylori (Hp);AB-PAS and HID-AB mucinous staining was used to distinguish intestinal metaplasia subtypes; the immunohistochemical Elivision method was used to determine the expressions ofmtp53 and c-myc protein;indirect ELISA was used to determine Hp-CagA.Results Forty-five cases with incomplete colonic epithelial metaplasia,47 cases with incomplete type intestinal metaplasta,17 cases with complete colonic epithelial metaplasia,16 cases with complete intestinal metaplasia.The positive rate of Hp-CagA in all intestinal metaplasia subtypes was higher than that in non-atrophic gastritis,but there was no significant difference (P ＞ 0.05).The expression of mtp53 protein in incomplete colonic type of intestinal metaplasia with Hp-CagA positive was higher than that in incomplete colonic type of intestinal metaplasia with Hp-CagA negative (x2 =5.494,P ＜ 0.05).The expression of c-myc protein in incomplete colonic type of intestinal metaplasia with Hp-CagA positive was higher than that in incomplete colonic type of intestinal metaplasia with Hp-CagA negative (x2 =13.950,P ＜ 0.01).Conclusion Hp-CagA is a sort of highly virulent strain,and Hp-CagA may do a strong role in the promotion of gastric atrophy and intestinal metaplasia.

Objective To investigate the changes of TNF-?,IL-2 and IL-1? level in serum of patients with viral myocarditis and its clinical meaning.Methods The level of serum TNF-?,IL-2 and IL-1? in 45 cases of viral myocarditis was detected by ELISA,and the data were compared with control group.Results Serum TNF-?,IL-2 and IL-1? levels in viral myocarditis patients were significantly higher than control group and related to severity of the disease.Conclusion It suggests that immune dysfunction exists in patients with viral myocarditis.Higher level of TNF-?,IL-2 and IL-1? may be associated with development of the viral myocarditis,and it can be a new indicator for viral myocarditis.

OBJECTIVETo study the relationship between allergic rhinitis and fractional exhaled nitric oxide (FeNO).METHODS FeNO was measured in 66 allergic rhinitis patients before and after treatment. Visual analogue scale (VAS) score was used to describe the patient's symptoms. RESULTSFeNO and VAS score were significantly decreased after treatment (t=4.25,P=0.0000;t=3.34, P=0.0008), and the decrease proportion were (14.56±27.23)% and (8.68±53.17)% respectively. Correlation analysis showed FeNO and VAS score was significantly correlated before (r=0.43,P=0.0003) and after (r=0.45,P=0.0002) treatment. After treatment, the decreased proportion of FeNO and VAS score were significantly correlated (r=0.25,P=0.0437). CONCLUSIONFeNO can provide objective evidence for the treatment efficacy of allergic rhinitis.

Aim To investigate the myocardial hypertrophy,the expression of transforming growth factor ?1(TGF-?1),Smad3 and Smad7 proteins in spontaneous hypertensive rats(SHR)and the effects of benazepril and candesartan.Methods SHRs of 12 weeks old were given benazepril and candesartan for 12 weeks.The tail arterial pressure was measured every two weeks.At 12 th weekend,cardiac configuration,heart mass index,area of cadiocytes,concertrations of AngⅡin plasma and myocardium,expressions of TGF-?1、Smad3 and Smad7 proteins were measured respectively.Results The arterial pressure,wall thickness,heart mass index,area of cardiocytes and the expressions of TGF-?1,Smad3 proteins increased in SHRs but were attenuated after the treatment of benazepril or candesartan.After the combined treatment,the synergistic effect could be observed.The levels of cardiac tissue and plasma AngⅡwere reduced.The expressions of Smad 7 were up-regulated after the treatment of benazepril or candesartan,while they were stable after the combined use.Conclusion There is a synergistic effect of attenuating myocardial hypertrophy in SHRs by combined use of benazepril and candesartan.It may be related to the regulation of Ang Ⅱ,decreasing the expressions of TGF-?1 and Smad3.
