Soft liner materials for denture are applied on the surface of denture base, and present elasticity after solidification. These materials ameliorate the impacted biting force, and relieve or eliminate the tenderness. Moreover, they can gather denture base with alveolar crest closely, and improve dentural retention. Due to the specific physico-chemical properties, soft liner materials play an amortization role between denture base and alveolar crest, and are applicable to the complete denture restoration in patients with serious depauperation of alveolar crest. The properties of soft liner materials vary with different factors, thus affecting the exertion of function. The aim of this paper is to analyze the bonding strength, hydroscopicity and dissolubility, micro-organism attachment, together with aging resistance of soft liner materials, besides, to investigate the influential factors on the physico-chemical properties of soft liner materials for denture, further modify their properties and exert better functions.

This paper reported the history of avian flu outbreaks in China from 1996 to 2006, directed the characteristics of avian influenza outbreaks in recent years. China is one of the biggest poultry producers in the world and many migratory birds go through China, China faces high risk of pandemic bird flu. The continuing occurrence of sporadic human cases indicates that the virus is continuing to circulate in birds in some parts of the country. In the fighting again avian flu virus, China has developed some possible practice on precautionary and control measure. China enhances international cooperation and scientific involvement in the prevention and control of the avian flu. The State Council and Ministry of Agriculture issued the laws and regulations on avian flu. Wild birds may have played a role in getting domestic fowl and human beings infected with bird flu. Poultry manure is considered to be another key source of the spread routes of H5N1 virus, but the bio - security processing in free range poultry farming and waste products is very poor disposition in China. Epidemic control at grassroots level still needs to be strengthened.

Objective:To analyze KCNJ5 mutation of adenomas in patients with aldosterone-producing adenoma (APA) companying with hypokalemia, and to compare the clinical characteristics of patients with and without KCNJ 5 mutations.Methods:Clinical data of 144 APA patients were retrospectively analyzed. DNA were extracted from adenoma tissues, and amplified and sequenced for KCNJ5 gene. The serum potassium level and cardiac complications in patients with and without KCNJ5 gene mutation were compared.Results:Among 144 tumors, 131 tumors (91%) had KCNJ5 mutation, including 68 tumors with G151R, 56 tumors with L168R, 5 tumors with E145Q, and two tumors with novel mutations, V156_K160delITE and G151delinsVR. Compared with patients without KCNJ5 mutation, patients with KCNJ5 mutation had lower preoperative serum potassium levels, more cardiac complications, lower postoperative systolic blood pressure, and better postoperative hypertension relief. There were no statistical differences in age, gender, blood pressure, serum potassium level, plasma renin activity or plasma aldosterone concertration.Conclusion:91% adenomas in patients with APA and hypokalemia had KCNJ5 mutation, suggesting that KCNJ5 mutation is the main cause in these patients.

Purpose To investigate the expression and clinical significance of Foxp3 ( cell surface marker of regulatroy T) mRNA and its protein in endometrial carcinomas and normal endometrial tissues. Methods Real-time fluorescence quantitative PCR and immuno-histochemical SP methods were used to detect the expressions of mRNA and protein in tumor tissue of 84 cases of endometrial carcino-mas and 40 cases of normal endometrial tissue, then to analyze the relationship between Foxp3 gene and clinical pathological character-istics of endometrial carcinoma specimens, such as differentiation, FIGO stage. Results Foxp3 mRNA and it′s protein expression of endometrial carcinomas were significantly higher than that of normal endometrial tissues. There were significantly relationships between Foxp3 mRNA expression and FIGO stage of endometrial cancer, Foxp3 mRNA expressions of III+IV stage was higher than that ofⅠ+Ⅱ stage endometrial carcinoma (P<0. 05). But the relationship between Foxp3 expression and differentiation degree reached differ-ent conclusions in the two detection methods. By immunohistochemistry the expression of Foxp3 protein was correlation with histological differentiation grade (rs =0. 72, P <0. 01). In poorly differentiated endometrial carcinoma Foxp3 + cell number was significantly higher than that in well differentiated endometrial carcinoma. By detection of real-time fluorescence quantitative PCR method, Foxp3 mRNA expression was not correlated with tumor grade (rs =0. 01, P=0. 35). Conclusion Foxp3 in endometrial carcinomas are high expressions. Immunohistochemical method has more clinical value than real-time fluorescence quantitative PCR test results. Foxp3 may be involved in the regulation of the development of endometrial cancers.
