Objective To systematically review the effectiveness of amiodarone in treating repurfusion arrhythmia (RA) after thrombolytic therapy for acute myocardial infarction (AMI), so as to provide high quality evidence for formulating the rational thrombolytic therapy for AMI. Methods Randomized controlled trails (RCTs) on amiodarone in treating RA after thrombolytic therapy for AMI were electronically retrieved in PubMed, EMbase, The Cochrane Library (Issue 3, 2012), CBM, CNKI, VIP and WanFang Data from inception to January, 2013. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed quality. Then RevMan 5.1 software was used for meta-analysis. Results A total of 5 RCTs involving 440 patients were included. The results of meta-analysis suggested that, compared with the blank control, amiodarone reduced the incidence of RA after thrombolytic therapy in treating AMI (RR=0.60, 95%CI 0.48 to 0.74, Plt;0.000 01) and the incidence of ventricular fibrillation (RR=0.47, 95%CI 0.26 to 0.85, P=0.01). It neither affected the recanalization rate of occluded arteries after thrombolytic therapy (RR=1.00, 95%CI 0.88 to 1.15, P=0.94) nor decreased the mortality after surgery (RR=0.33, 95%CI 0.10 to 1.09, P=0.07). Conclusion Current evidence indicated that, amiodarone can decrease the incidence of RA. Unfortunately, the mortality rate can’t be reduced by amiodarone. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion
Backgroud Iodine deficiency is the main cause for potentially preventable mental retardation in childhood and is still prevalent in large parts of the world. Objectives To assess the effects of iodised salt in comparison with other forms of iodine supplementation or placebo in the prevention of iodine deficiency disorders.Search strategy We searched the Cochrane Library, Medline, the Register of Chinese trials developed by the Chinese Cochrane Centre, and the Chinese Med Database. We performed handsearching of a number of journals (Chinese Journal of Control of Endemic Diseases, Chinese Journal of Epidemiology, Chinese Journal of Preventive Medicine, and Studies of Trace Elements and Health up to February 2001), and searched reference lists, databases of ongoing trials and the Internet. Date of latest search: November 2001. Selection Criteria We included prospective controlled studies of iodised salt versus other forms of iodine supplementation or placebo in people living in areas of iodine deficiency. Studies reported mainly goitre rates and urinary iodine excretion as outcome measures. Data collection amp; analysis As the studies identified were not sufficiently similar and not of sufficient quality, we did not do a meta-analysis but summarised the data in a narrative format. Main results We found six prospective controlled trials relating to our question. Four of these were described as randomised controlled trials, one was a prospective trial that did not specify allocation to comparison groups, and one was a large population-based study comparing different interventions. Comparison interventions included non-iodised salt, iodised water, iodised oil, iodation with potassium iodide versus potassium iodate. Numbers of participants in the trials ranged from 35 to 334; over 20 000 people were included in the population-based study. There was a tendency towards goitre reduction with iodised salt, although this was not significant in all studies. There was aim an improved iodine status in most studies (except in small children in one of the studies), although urinary iodine excretion did not always reach the levels recommended by the WHO. Reviewers’ conclusions The results suggest that iodised salt is an effective and safe means of improving iodine status. However, high quality controlled studies are needed to address questions of dosage and best means of iodine supplementation in different population groups.
目的 探讨碘131(131I)治疗后Graves眼病(GO)预后与血清促甲状腺激素受体抗体(TRAb)水平变化之间的关系。 方法 选择2011年5月-12月初发Graves病患者238例,分为GO组124 例和非GO组114 例,分别检测131I治疗前及131I治疗后2、3、6个月甲状腺功能和TRAb,GO患者131I治疗前和治疗后6 个月进行临床活动度评分(CAS)。 结果 131I治疗前各组TRAb水平差异无统计学意义(P>0.05),TRAb水平与GO CAS评分之间无相关;131I治疗后6个月所有患者TRAb水平显著增加;非GO组有5例新发GO,新发GO组与其他患者的TRAb水平分别为(58.7 ± 77.9)、(61.9 ± 81.1)U/L,差异无统计学意义(P>0.05);GO组又分为GO无变化29例,GO加重17例,GO缓解78例,三组患者TRAb水平分别为(53.5 ± 77.6)、(66.2 ± 89.9)、(66.8 ± 42.2)U/L,差异无统计学意义(P>0.05)。 结论 131I治疗后患者TRAb水平显著增加,但TRAb水平的变化和GO预后无关,TRAb与GO的关系还需要进一步研究。

Objective To reveal the relationship between the iodine nutrition and the change of spectrum of thyroiddiseases by analyzing the change of spectrum of thyroid diseases in different iodine environments before and after the implementation of universal salt iodization (USI). Methods To compare the urinary iodine concentration between the normal people (1 000 cases) and the patients with thyroid diseases (5 998 cases) by surgical operations who were from 4 cities of Guangxi Zhuang Autonomous Region, covering the iodine deficient areas and the iodine rich areas. Results After the USI was put into practice, the proportions of nodular goiter decreased, but the proportions of toxic nodular goiter, thyroid papillary carcinoma, and Hashimoto thyroiditis were higher than those before USI (P<0.05). The urinaryiodine concentrations of nodular goiter, Graves disease, toxic nodular goiter, thyroid papillary carcinoma, and Hashimotothyroiditis were higher than those before the measure was taken (P<0.05). The urinary iodine concentration of patients with thyroid was higher than that of normal people (P<0.05), and the urinary iodine concentration of patients with thyroidand normal people was higher than those before the USI (P<0.05). Conclusions The change of spectrum of thyroid diseases in Guangxi Zhuang Autonomous Region is obvious within 10 years after USI had been taken. The excessive intake of iodine may be one of the dangerous factors leading to toxic nodular goiter, thyroid papillary carcinoma, and Hashimoto thyroiditis.
【Abstract】Objective To study the relation between iodine and experimental autoimmune thyroiditis(EAT). Methods Establishment of animal model was performed with iodine and thyroglobulin(TG).The rats were randomly divided into 5 groups: normal control group(NC), low iodine group (LI,500 μg/L), high iodine group(HI,500 mg/L), TG+Freund adjuvant group(TG) and TG+Freund adjuvant+HI group(TG+HI). The rats in TG group and TG+HI group were rejected hypodermically with TG emulsified by complete Freund adjuvant, and strengthen immunity was conducted with TG emulsified by incomplete Freund adjuvant on 15 days. After that, strengthen immunity was done weekly till the end of the experiment. Serum TGAb and TPOAb were measured by radioimmunoassay. Observation of the pathological changes of thyroid gland was also done. Results Thyroid follicular destruction and lymphocytic infiltration in the TG+HI group (3.83±1.72) and HI group (3.00±0.89) were significantly higher than that of the NC group(0.67±0.82),P<0.05. The results of the TG group were higher compared with the NC group, but there were no significant differences between them(Pgt;0.05). The levels of TGAb in the TG+HI (4.990±1.505),HI (3.589±1.240) and TG group (4.883±1.198) were significant higher than those of the NC group (0.642±0.454) and the LI group (0.707±0.240),P<0.01. The levels of TPOAb in TG+HI group (1.475±0.523) and TG group (1.316±0.606) were significantly higher than those of the NC group (0.365±0.196) and the LI group(P<0.01). Serum TGAb and TPOAb levels were positively correlated with the histological grades of lymphocytic thyroiditis(r=0.9,P<0.05). Conclusion Excessive iodine intake may induce the occurrence of EAT. The induction of EAT with excessive iodine and TG may be more efficient.
131I was labeled on lipiodol molecule by an iodine exchange reaction. The labeling rate was 95%. No dehalogenation was detected within 15 days at room temperature or after slerilization. Animal experiments showed that after hepatic arteial injection, 131I-lipiodol was selectively accumulated in the embolizated local area. No increased acti-vity was observed in thyroid, lung or other areas in the body. The blood radioactivity per ml was 0.09±0.04% of the injectd dose. The result suggest that 131I-lipiodol is very stable and suitable for clinical application.
