3.WIF-1 and the diagnose and treatment of lung cancer
International Journal of Surgery 2013;40(12):835-837
Wingless type protein (Wnt protein) is a group of protein which plays an important role in the process of animal growth and hemopoiesis,the signaling pathway they conducted was called Wnt signaling pathway,and its abnormal activation can lead to many tumors,include lung caner.As a tumor suppressor gene,WIF-1 can restrain the activation of Wnt signaling pathway,which can avoid lung cancer.WIF-l's methylation can downregulate the expression of WIF-1,which can activate Wnt signaling pathway and cause lung cancer.So the detection of WIF-1's methylation may contribute to clinical diagnose of lung cancer,and therapy of WIF-1 's methylation may be one of the treatment metheds of lung cancer.

Objective To comprehend the action mechanism of simvastatin in pulmonary hypertension(PH)when it induced by high pulmonary blood flow.Methods Abdominal aorta-inferior vena cava shunting was made in rats to establish animal model of PH induced by high pulmonary blood flow,simvastatin with dose of 2 mg/(kg?d)was used to interfere for 11 weeks.And then,pulmonary arterial pressure,apoptosis rate and proliferation rate of pulmonary vascular smooth muscle cell were determined.Results were compared with other groups.Results Simvastatin could cut down the pulmonary arterial pressure well,pulmonary arterial pressures of simvastatin group rats were lower than those of spliting groups obviously(Pa

Objective To evaluate the plasma level of amino-terminal pro-brain natriuretic peptide(NT-proBNP) before and after treatment in children with dilated cardiomyopathy (DCM) and explore the relationship between NTproBNP and heart functional classes.To evaluate the significance of dynamic change in NT-proBNP level in children with dilated cardiomyopathy.Methods The study comprised 49 children with DCM from Aug.2011 to Sep.2013 in Hunan Children's Hospital.NT-proBNP levels were measured before and after treatment.All the patients were evaluated under the modified Ross Heart Association functional class and echocardiographic determination of left ventricular ejection fraction(LVEF) and fractional shortening(SF).The patients were divided into improvement group(38 cases) and the non-improvement group(11 cases) according to cardiac function after treatment.Results The plasma level of NTproBNP was positively correlated with Ross heart failure classification (r =0.756,P < 0.01),and much better than LVEF and SF.To identify mild heart failure,the cut-off value of 329 ng/L was 93.8% sensitive and 90.9% specific.To identify moderate heart failure,the cut-off value of 2 833 ng/L was 95.6% sensitive and 92.9% specific.To identify severe heart failure,the cut-off value of 12 125 ng/L was 80.6% sensitive and 84.8% specific.There was significant difference in the improvement group before and after treatment(t =2.357,P < 0.05).In non-improvement group there was no significant difference (t =0.132,P =0.778) before and after treatment.Conclusions There is significant correlation between the plasma level of NT-proBNP and heart failure severity.The dynamic changes in NT-proBNP levels before and after treatment can help us to determine the effect of treatment and prognosis.

The genus Scilla consists of 90 species widely distributed in Europe, Asia and Africa, one and its variant of which can be found in China Some species of the genus have been used in traditional medicine to treat various diseases related to inflammation and pain. Phytochemical studies have demonstrated the presence of triterpene and tritepenoid saponins derived from eucosterol, bufadienolides, alkaloids, stilbenoids and lignan in the plants of this genus. Various bioactivities such as antimicrobial, anti-inflammatory, antioxidant, anti-tumor and glycosidase inhibitory activities, have been reported. In this review, the advance of chemical constituents and pharmacological activities of the Scilla species are summarized for further development and utilization of the resource.
