OBJECTIVETo explore the techniques of epicanthoplasty.

METHODSThe epicanthoplasty was designed based on the principle of transverse-vertical plasty. The skin between the new medial canthal point and lower lacrimal point was undermined subcutaneously. The displaced orbicularis oculi muscle was released and the medial canthal tendon was shortened. Then the skin was redistributed.

RESULTSFrom Oct.2006 to Nov. 2007, 118 cases were treated. The patients were followed up for 3-15 months. The cosmetic results were satisfactory with no relapse and inconspicuous scar.

CONCLUSIONSThe modified epicanthoplasty is very practical technique for clinical application with a good long-term effect.

Objective:To preliminarily study the effect of Louqin Zhisou decoctions with the mechanism of clearing heat and resol-ving phlegm on the blood level of neutrophil elastase ( NE) in the rat model of acute exacerbation of chronic obstructive pulmonary dis-ease ( AECOPD) . Methods:The rat model of AECOPD was established by passive cigarette smoking, intratracheal instillation of li-popolysacchricle ( LPY) and intranasal instillation of staphylococcus aureus. Totally 60 AECOPD rats were randomly divided into 3 groups, the model control group (n=20), ambrohexel group (n=20), and Louqin Zhisou decoctions group (n=20). NE was detec-ted by ELISA. Results:Compared with that before the treatment, NE in ambrohexel group and Louqin Zhisou decoctions group was de-creased significantly(P<0. 01). Conclusion:Clearing heat and resolving phlegm method probably can decrease NE by reducing air-way mucus hypersecretion and obstruction in AECOPD rats.

Objective: To investigate the ⁹⁰Sr concentration levels in the monitoring areas and the control area at Ningde Nuclear Power Plant (NPP). Methods: Food samples were collected from the monitoring areas in 30 km of Ningde NPP and the control area far away. The radioactive levels of ⁹⁰Sr in food samples were analyzed using the chromatography with 2-(2-ethylhexyl) phosphate fast extraction method. Results: In this survey, ⁹⁰Sr radioactive concentrations in 30 varieties of foods in 6 categories were analyzed. In the monitoring area, ⁹⁰Sr radioactivity concentration in the samples collected were in the range of 0.017-1.830 Bq/kg for cereals, beans and potatoes, 0.021-0.318 Bq/kg for vegetables, 0.007-7.690 Bq/kg for quatic products, and 0.009-0.184 Bq/kg for meats; whereas, in the control area, cereals, beans and potatoes in 0.017-0.700 Bq/kg, vegetables in 0.034-0.677 Bq/kg, aquatic products in 0.038-3.360 Bq/kg, and meats in 0.019-0.054 Bq/kg. Conclusions The ⁹⁰Sr radioactive concentrations in foods were far below the food standard limits in this survey. The contribution of evaluated to the public from the ⁹⁰Sr in foods was neglectable.

Objective To investigation the radioactivity level of ⁹⁰Sr in tea leaves within and outside 30 km range of Ningde nuclear power plant. Methods The tea leaves within and outside the 30 km range of Ningde Nuclear Power Plant were collected from 2013 to 2018. According to“Radiochemical analysis of strontium-90 in water and ash of biological samples” (HJ 815—2016), the separation and analysis of ⁹⁰Sr-⁹⁰Y were carried outusing the method of di (2-ethylhexyl) phosphate (HDEHP) chromatography. Results During the period of 2013-2018, the radioactivity concentrations of ⁹⁰Sr in the tea leaves within the range of 30 km around the Ningde nuclear power plant were 0.486～13.29 Bq/kg and that of ⁹⁰Sr in the tea leaves outside the range of 30 km around the nuclear power station were 1.021～17.19 Bq/kg. Conclusion During the six years of operation in Ningde Nuclear Power Plant, there was no increase in the radioactivity level of ⁹⁰Sr in the tea leaves around the nuclear power plant.
