Chinese Journal of Endocrinology and Metabolism 1986;0(04):-
Objective To observe the effect of tea polyphenols on proliferation, invasion and apoptosis of human thyroid papillary carcinoma cells (CGTH W-3) in vitro. Methods The effects of various concentrations of tea polyphenols on proliferation, invasion and apoptosis of CGTH W-3 cells were observed by MTT assay, plate scarification assay and flow cytometer, respectively. Results Tea polyphenols(50-400 mg/L) inhibited the proliferation of CGTH W-3 cells with dose-and time-dependent manners. The IC_50 of tea polyphenols to CGTH W-3 cells was 240 mg/L (1st day), 229 mg/L (3 rd day), 200 mg/L (5th day) and 118 mg/L (7th day). The cell free zoster which reflected the invasive ability was widened by tea polyphenols. The apoptosis percentage of CGTH W-3 cells incubated with tea polyphenols for 48 h was obviously increased, with 3.51% in control group, 12.61% with 100 mg/L tea polyphenols, 52.97% with 200 mg/L tea polyphenols and 70.79% with 400 mg/L tea polyphenols (all P

Objective To observe the effects of salmeterol/fluticasone on the bone metabolism and bone density of the patients with moderate COPD and whether the effects is relate with inhaled corticosteroid course. Methods Sixty pa-tients with COPD were divided into 2 groups by random digit table. Patients in experimental group (n=30) were given conven-tional therapy with salmeterol/fluticasone one inhale(bid) for continuously 12 months while patients in control group (N=30) were given conventional therapy without any glucocorticoid.The bone mineral density (BMD) of the femoral triangle in all patients were measured by DXA before therapy, 3 months and 12 months after therapy. At the same time, biochemical indi-cators that are correlated with bone metabolism include bone gla protein (BGP) and alkaline phosphatase (ALP) were mea-sured by radioimmunoassay. Results The BMD, BGP and ALP of patients in experimental group and in control group be-fore therapy, 3 month and 12 month after therapy were compared. There is no significant difference (P>0.05) between these two groups before therapy and after 3 month but significant difference was shown after 9 months (P<0.05). Conclusion Short period inhaling salmeterol/fluticasone in patients with COPD is safe. But long-term inhaling salmeterol/fluticason may lead to decline of the bone density in patients with COPD.

Objective Reviewing the experience in the diagnosis and treatment of cases with aorta-pulmonary septal defect and aortic origin of right pulmonary artery complicated with interruption of the aortic arch. Methods Reviewed clinical data from medical records for5 patients (4 boys and 1 girl, age from 1 to 18 years on admission) who had been treated in Wuhan Asia Heart Hospital between 2005 and 2009. Results All cases had type A interruption of the aortic arch ( according to Celoria and Patron's Classification) , type Ⅱ aorta-pulmonary septal defect( according to Mori Classification) and aortic origin of right pulmonary artery complicated with interruption of the aortic arch. Large patent ductus arteries were observed in all cases,and no cardiac abnormality such as ventricular septal defect was found. All patients received echocardiography and spiral CT examination, and 3 of them over 10 years of age received cardiac catheterization and angiography for the evaluation of the pulmonary artery pressure. Two patients, at the age of 14 and 18 years, had severe pulmonary hypertension and declined to receive the operation. One of the 2 cases had hemoptysis and was given prostacyclin ( Iloprost solution for inhalation, a drug for pulmonary artery hypertention ) for reducing the pulmonary pressure. The patient now has an improved cardiac fu0ction without recurrent hemoptysis. One 14-year-old case gave up the operation because of the financial problem and failed to communicate with us after discharge. Radical surgery was performed in the remaining three cases, one had serious infection in the lung and died 11 days after the operation, in one case ( 2 years old) pulmonary artery hypertension has been persisted even though drug therapy was given for a long time and was found at a poor cardiac function 18 months after the operation. One patient recovered well under routine drug therapy and has been followed-up. Conclusion Aorta-pulmonary septal defect and aortic origin of right pulmonary artery with interruption of the aortic arch ( with intact ventricular septum) are different from the classic triad of inter ruption of the aortic arch, consisted of the interruption of the aortic arch, patent ductts arteriosus and ventricular septal defect.It should be considered as a special kind of cardiovascular malformation syndrome. Echocardiography can be used for the preliminary diagnosis of aorta-pulmonary septal defect and aortic origin of right pulmonary artery with interruption of the aortic arch. The final diagnosis and decision for surgery should be based on the combined information from cardiac catheterization,cardiovascular angiography and spiral CT examination. Pulmonary artery pressure and resistance are the most important factors,because they have great effects on the duration of surgery and the outcome. A radical operation is necessary for all cases, but the mortality rate is high. The prognosis would be great if only the patient can survive successfully during the peri-operative period, a period with a poor cardiac function, potential lung infection and the pulmonary artery hypertension.
