Objective To analyze the regulation of NEF3 expression in SH - SY5Y after RA induction. Methods The expression of NEF3 and Brg1 genes was individually detected by realtime RT - PCR and Western blot analyses. Then, the CAT reporter driven by 5' flanking region ofNEF3 gene (pBLCAT3 -2. 8k - NEF3) was co - transfccted with eukaryotic expression plasmids of pBJ5 - Brgl or pBJ5 - Brg1 - NTP into SH - SY5Y respectively. Promoter activity of the NEF3 gene was detected by competitive RT - PCR assay. Results Similar changes in the mRNA expression of NEF3 and Brg1 and that of the protein expression of Brgl were detected in Sh - SY5Y cells af-ter RA treatment for 12 -24h. Wild type Brgl can promote the expression of pBLCAT3 -2.8k -NEF3 promoter after RA induction, but not mutant Brg1. Conclusion Brgl helpes regulating the expression of NEF3 gene possibly via changes in chromatin conformation in the SH -SY5Y cells after RA induction.

The result of a nutritional survey on potassium intakes of population and serum potassium contents of healthy adults in Shanghai (high occurrence of hypokalemia), Sichun (moderate occurrence of hypokalemia) and Shandong (null occurrence of hypokalemia) revealed that the average daily potassium intakes for the three areas were 60.1?16.6, 54.6? 13.4 and 58.7? 11.1 mmol per capita per day respectively; The serum potassium contents of the three areas were 4.2?0.3,4.0 ?0.3 and 4.2?0.4 mmol/L respectively. These results indicated that the daily potassium intakes and serum potassium contents between Shanghai and Shandong were not significantly different and might suggest that the occurrence of gossypol related hypokalemia in Shanghai and Sichun could not be attributed to the low potassium intakes and low serum potassium contents of the population.

Objective To explore the effect of extended care on the quality of life of patients with permanent colostomy . Methods Clinical data of 268 patients with permanent colostomy were retrospectively analyzed. The patients were randomly divided into the experiment group (n=154) and control group (n=114). Two groups of patients after colostomy were given conventional nursing and telephone follow-up and the experiment group also received extended care such as home visits , seminars and fraternity care. Postoperative follow-up was done for 1 month, 3 months, 6 months, 9 months and 1 year. Core quality of life questionnaire (QLQ C30) was used to investigate the patients after 1 year intervention. Result Compared with the control group, patients′physical function, role function, emotional function, cognitive function, social function and health status rating were significantly improved in the experiment group (P<0.05). Conclusion Extended nursing can provide more comprehensive, systematic, professional nursing, improve the mastery of relevant knowledge and the skills and finally improve patients′quality of life.
