Objective To analyze comprehensively the monitoring data of iodized salt in Zhangjiakou city during 2001 to 2009, and to provide basic information for working out control strategies of the iodine deficiency disorders. Methods According to the iodized salt monitoring requirements in National Iodine Deficiency Disorders Monitoring Program of Ministry of Health, a batch of nine salt samples were taken from each processing (wholesale)company of each county or district of the seventeen counties(districts) of Zhangjiakou once a month. Two townships (towns, street offices) were selected by their location of east, south, west and north in each county(district), and a township in central area each year. Four villages(neighborhoods) were selected in each township(town, street office),and eight household salt samples were collected in each village(neighborhood), and quantitatively determined by direct titration of iodine. Results Iodized salt processing(wholesale) : during 2001 to 2009, a total of 1728 batches was monitored, 1689 batch qualified, batch qualification rate 97.74%;15552 salt samples were tested, 15 357 qualified, iodized salt qualification rate 98.75 %. Household salt levels : 5297 villages (neighborhoods) of 1305 townships(towns, street offices) were monitored, 44 316 salt samples were collected, 43 274 qualified, iodized salt qualification rate 98.04%(43 274/44 141 ), iodized salt coverage rate 99.61%(44 141/44 316), qualified iodized salt consumption rate 97.65%(43 274/44 316). Rate of non-iodized salt was 0.40%(260/44 316), and salt median iodine was 30.02 mg/kg. Conclusions The iodized salt quality indicators are within the state-controlled range in Zhangjiakou city for nine years which remaines at relatively stable levels with a smaller range of annual fluctuations.Detection of non-iodized salt over the years has become the main factors affecting the effectiveness of the prevention and control measures.We should increase monitoring,supervision,and universal health education,and prevent the spread of non-iodized salt.

Novozym 435 was selected from four lipases and two proteinase because of its high catalytic activity and enantiosectivity.For the ammonolysis of (?)-?-methylbenzyl acetate,The effect of ammonia sources,the concentration of enzyme and substrates on the reaction were further explored .under the optimum conditions of this study,after 6h reaction,with the enantiomeric excess of the remaining (-)-?-methylbenzyl acetate was found to be higher than 99%.

The effects of reaction media, water activity, temperature and pH on Novozym 435-catalyzed enantiose-lective ammonolysis of (?) -?-methylbenzyl acetate have been systematically explored. Novozym 435 showed high catalytic activity and enantioselectivity in hexane; the optimum temperature and the initial water activity were 25℃ and 0.33 respectively; The suitable reaction pH was in the range of 6.0 - 7.0.

Objective To assess the efficacy of two antibiotic prophylactic regimens in a prospective randomized trial in 1 year for patients undergoing insertion of catheters,and to provide the evidence for uniform consensus existing on the timing,route,and choice of antibiotic.Methods During a period of 12 months,78 patients,who consecutively entered the peritoneal dialysis programme,[45 women and 33 men,mean age (48.2?15.7)years] were included.The prophylactic regimens were a single dose of ceftriaxone (1.0 g) given intravenously 30 minutes before surgery (Group A) and given cefazolin (0.25 g/L) i.p.in the each dialysis bag for 3 days postoperatively (Group B).All operations were performed in one room.The wound was observed every day,and body temperature,Count of white blood corpuscle and type,dialysate were examined every day. Results In Group A and B,none of the patients showed peritonitis or wound infection during the post-operative period (within 10 days).One of 39 patients(2.5%) in the group A,and 2 of 39 patients (5.1%) in the group B had exit site infection (P＞0.05).Conclusions There is no significant difference in the incidence of peritonitis and wound infection between two groups. Prophylactic preoperative single-dose antibiotics intravenously do as well as antibiotics given intraperitoneally for peritoneal dialysis catheter insertion,but is much more convenient.

A total of 127 type 2 diabetic patients were divided into low glycemic index meal replacements (intervention) group and standard food-based diet (reference) group in an experiment for 12 weeks.The results showed that fasting plasma glucose,postprandial 2 h plasma glucose,fasting insulin,and homeostasis model assessment insulin resistance(HOMA-IR) in the intervention group decreased significantly after 12 weeks trial ( P＜0.05 or P＜0.01 ).However,there were no significant changes in lipid profile and HbA1C in intervention group.In addition,percentage of body fatty,visceral fatty area,and waist-hip ratio also decreased in intervention group( all P＜0.01 ).Superoxide dismutase and glutathione levels increased significantly in intervention group by the end of trial (both P＜0.01 ),while malondialdehyde was decreased (P＜0.01 ).There were no significant changes in the aforementioned indices in the reference group.Weight,body mass index,and waist circumferences were decreased in both groups,but without significant difference between the two groups.

OBJECTIVETo investigate the effects of small interfering RNA targeting connective tissue growth factor (CTGF) on rat transforming growth factor beta (TGF beta)/Smads signal pathway.

METHODSChemically synthetic siRNA targeting CTGF was transfected into HSC T6 and then they were injected into rat livers through their intraportal veins. At the same time these rats also received CCl4 subcutaneously every three days for 6 consecutive weeks. Untreated HSC T6 or/and rats with random siRNA treatment served as controls. Total RNA or/and protein in HSC T6 and rat hepatic tissues were extracted. The expressions of CTGF and TGF beta 1, Smad2, 3 and 7 genes were detected by reverse transcription-polymerase chain reaction (RT-PCR) and/or Western blot.

RESULTSCTGF siRNA significantly reduced the expression of CTGF protein in HSC T6. At 48 h after CTGF siRNA treatment, the down-regulation of CTGF protein was the most significant, up to 94%+/-4% (t=46.196, P less than 0.01), but the expressions of TGF beta 1, Smad2, 3 and 7 mRNA showed no differences in HSC T6 compared with the blank controls. Six weeks after CCl4 injections, prominent up-regulations were observed in the gene expressions of CTGF and TGF beta 1 in saline control or siRNA-treated rat livers. Administering CTGF siRNA for six weeks markedly attenuated the induction of CTGF and TGF beta 1 genes; the expressions of CTGF and TGF beta 1 protein decreased by 95%+/-2% (F=21.234, P less than 0.01) and 74%+/-8% (F=13.464, P less than 0.05), respectively, whereas Smad2, 7 protein expressions were not affected.

CONCLUSIONSilencing the CTGF gene can suppress the TGF beta /Smads signal pathway in rat livers.
