Objective To investigate the influence of nebulized Pulmieort respules inhalation after endoscopic sinus surgery (ESS)on the expression of epithelial Na~+ channel(ENaC)protein in nasal mucosa. Methods Forty-four patients with nasal polyps undergoing ESS were randomly divided into Pulmieort respules treatment group(n=21,nebulized Pulmieort respules inhalation for 10 d after ESS)and Rhinocort control group(n=23,Rhinoeort aqueous nasal spray for 10 d after ESS).All the patients were performed biopsy of membrane on the residual middle turbinate 14 d after ESS,eosinophils (Eos)and neutrophils(Neu)per hundred inflammation cells were counted under microscope during ESS and after ESS,and the expression of ENaC protein was detected by immunofluorescence assay. Results The percentages of Eos and Neu decreased in two groups after treatment,and the percentage of Neu in Pulmieort respules treatment group was significantly lower than that in Rhinoeort control group(P<0.05).The expression of ENaC protein after treatment in Pulmieort respules treatment group was significantly lower than that in Rhinoeort control group(P<0.01). Conclusion Application of pulmieort respules after ESS can decrease Neu infiltration and inhibit expression of ENaC protein,which can relieve acute inflammation and edema of nasal mucosa.

Three hybridomas producing monoclonal antibodies (Mab) to zona pellucida of porcine ovarian egg(ZP-OVA) were established(LPDg, LPC4, LPD,).Two Mab(LPD_8 LPC_4) were examined against human ovarian tissue by immunohistochemical technique in vitro. We found that the two Mab had cross-reaction with zona pellucida and ovum cytoplasm and no cross-reaction with membrana granulosa and theca folliculi. It showed that there were affinities of LPD_8 and LPC_4 to antigenic determinamts in the ovum cytoplasm and common antigenic components in zona pellucida and ovum cytoplasm. It suggested that the zona pellucida was derived from oocyte.

Objective To investigate the iodine nutritional status in the key populations before and after the adjustment of salt iodine content in Yantai of Shandong.Methods In 2010 (the pre-adjustment period) and 2014,2015 (the post-adjustment period),the changes in the residents' iodized salt,the goiter prevalence and urinary iodine of children aged 8-10,the urinary iodine of pregnant women,and the iodine content of drinking water before and after the adjustment were analyzed.Results The coverage rate of iodized salt and the edible rate of qualified iodized salt were 98.27％ and 97.28％,respectively before the adjustment of salt iodine content,and 97.44％ and 96.14％ after the adjustment.The mean of salt iodine after the adjustment (21.96 mg/kg) was significantly lower than that of 2010 (31.45 mg/kg,t =66.29,P ＜ 0.05).The goiter prevalence of children aged 8-10 by thyroid palpation was 0.92％ in 2010,while it was 1.89％ by ultrasonic in 2014,2015.There was significant difference in the iodine nutritional status of children in 2010 (191.0 μg/L) and in 2014,2015 (173.0 μg/L,Z =3.56,P ＜ 0.05).The difference of iodine nutritional status in pregnant women between pre-adjustment (154.0 μg/L) and post-adjustment (130.4 μg/L) was also significant (Z =5.54,P ＜ 0.05).The median of water iodine was 5.4 μg/L after the adjustment.There were 52 towns with medians of water iodine below 10 μg/L.Conclusions The coverage rate of iodized salt and the edible rate of qualified iodized salt have all met the national standard before and after the adjustment of salt iodine content.The mean of salt iodine during 2014,2015 is significantly lower than that of 2010.Before and after the adjustment,the goiter rates of children aged 8-10 are all below 5％.The adjustment of salt iodine content is more suitable to children aged 8-10 than to pregnant women currently.It is suggested that pregnant women eat more foods rich in iodine.
