Bronchial asthma is the most common chronic diseases in children.Asthma can not be fully explained by imbalance of Thl/Th2.With the research progress of CD4+ CD25+ Treg cell,it has been found that CD4+ CD25+ Treg cell related factors such as forkhead/winged helix transcription factor,heine oxygenase-1,transforming growth factor-?,cytotoxic T lymphocyte-associated antigen-4 are closely linked to asthmatic mechanisms.

The drugs such as sildenafil adulterated in herbal products and dietary supplements may endanger human health. The number of the new modified derivatives is increasing recently. Based on Q-TOF-MS, a new sildenafil analogue was found. It was isolated and purified by preparative liquid chromatography. Its structure was determined by NMR, as 1-[4-propoxy-3-(6, 7-dihydro-1-methyl-7-oxo-3-propyl-1H-pyrazolo[4, 3-d] pyrimidin-5-yl)phenylsulfonyl]-4-methylpiperazine. Compared with sildenafil, the ethoxy group of the benzene ring moiety was moved to the propoxy group, which had not been reported in China. The mass spectrometric behavior pattern of the structure type was summarized, which can greatly accelerate the structural analysis of novel analogues.

Objective To extract principal components from valuable indicators on conventional ultrasoundand contrast-enhanced ultrasound (CEUS) in the differential diagnosis of thyroid benign and malignant lesions and to discuss the diagnostic value of each indicator.Methods One hundred and three patients with 125 thyroid lesions (65 malignant lesions and 60 benign lesions) underwent preoperative grayscale ultrasound (GSUS),color Doppler ultrasound (CDUS) and CEUS examinations.Eighteen indicators were chosen to evaluate every lesion and principal components were extracted by principal component and valuable indicators were ordered by importance.Results There were significant differences on GSUS and CEUS indicators between benign and malignant lesions.The first principal component was the representation of contrast enhanced ultrasound and was valuable in the differential diagnosis of thyroid benign and malignant lesions.The rank of valuable CEUS indicators were homogeneity of enhancement,filling defect,relative arrival time of periphery,peak interior echogenicity,relative arrival time of interior,peak peripheral echogenicity and ring enhancement.Conclusions GSUS and CEUS are valuable in the differential diagnosis of thyroid benign and malignant lesions.

Objective To evaluate the theraputic effect of transcatheter arterial chemoembolization (TACE)for hepatocellular carcinoma with tumor thrombosis of portal vein.Methods One hundred and six patients of hepatocellular carcinoma with tumor thrombosis of portal vein under treament of TACE were observed before and after the procedure.Results After TACE tumor size reduced＞50% in 23 patients,＜50% in 25, no significant change in 44.The size of tumor enlarged in 12.The disappearance of portal vein tumor thrombosis accessed in 14,with reduction in 39,and no significant change in 51.Two patients died within one week.Conclusion TACE provides good therapeutic effect on hepatocellular carcinoma with tumor thrombosis of portal vein.
