Objective To discuss the strategy and intervention measures of the iodine deficiency disorders (IDD)control in coastal salt.producing areas so as to shoot the problem of non-iodized salt causing IDD.Methods Accordinng to different areas,periods and crowds,eomplicatd measures and strategies were taken such as supply of iodized salt to peopie in special need while universalizaion of iodized salt,health promotion,private salt factory censu8 and close.iodized salt quality monitoring and promotion of technology of iodized salt producion in Xiamen, where the probiem of non-iodized salt Was serious since 1995.Results Iodized salt manufactured Was qualified in a increased rate from 89.50% in 1995 to 96.17% in 1997,stablized at 99.00%since 2000.Qualified iodized salt sold in the shops waft increased from 87.33%in 1996 to 96.33%in 1998.Popularization covered by iodized salt in urban areas increaased from 0.92%in 1 995 to 100.00%in 2000,and it Was increased from 0 to 99.00%in suburban area8 and increased from 0 to 89.00%in rural areas.Since 2001 iodized salt covered up 93.00%of the people.The rate of child goitre in urban,suburban and rural areas respectively Wag 16.44%(228/1387), 20.57%(266/1293) and 24.93%(651/2611).Moreover,beginning from 1996,it reduced tO below of 5.00%respectively in 1999,2001 and 2005.The median of urinary iodine of children in urban,suburban and rural areas respectively was 137.50, 102.12,94.66 μg/L in 1995,since 1997 it reached 100.00μg/L and kept at 120.00μg/L In 2007 the median of urinarv iedine of children respectively was 271.10,240.40,198.10μg/L in urban,suburban and rural areas.The pereentage of awareness of IDD knowledge was 74.00%(444/600)in students in 1997 and reached 95.00% since 2000.Conclusion The paRern of eliminating iodine deficiency dis ease in Xiamen has successful established,which works efficiently and sets an example for iodized salt supplement in non-iodized salt areas and continually eliminating the iodine deficiency disease.

Objective:To observe the influence of radiofrequency catheter ablation of the fat pad at the right pulmonary vein- atria junction(RPV fat pad)on Bezold-Jarisch reflex(BJR)induced by veratridine in canine.Methods:Ten mongrel dogs were anesthetized and their chest were opened through a right thoracotomy to expose the RPV fat pad.Veratridine was injected into the left ventricle at bolus doses of 10?g/kg through a catheter to induce BJR.The sinus cycle length(SCL),systolic arterial pressure(SAP),diastolic arterial pressure(DAP),mean arterial pressure(MAP),left ventricle systolic pressure(LVSP), left ventricle diastolic pressure(LVDP)and mean left ventricle pressure(MLVP)were measured under the baseline and after ablation of the RPV fat pad;the changes of the above parameters(?SCL,?SAP,?DAP,?MAP,?LVSP,?LVDP,and?MLVP)were calculated.Then the same dose of veratridine was injected under the pad after ablation and the changes of the a- bove parameters were observed.Results:BJR was successfully induced in the 8 animals;the animals has prolonged sinus cycle length(SCL)and decreased MAP and MLVP.After ablation,the prolongation of SCL after injection of veratridine was markedly reduced([229.2?92.3]ms vs[39.3?14.1]ms,P

20% improvement in 4/7 primary indices.Sharp declines in several parameters were noticed during 3 to 6 months.Pain in 9 patients disappeared.There was also a statistically significant decrease in TNF ? transcripts in the PBMC.Conclusion Thalidomide is a reasonably promising drug for treating resistant ankylosing spondylitis and its biological mechanism is related to the gene expression suppression of proinflammatory cytokine TNF ?.
