ABSTRACT
Objective To investigate the distribution and characteristics of iodine excess areas in Liaocheng City of Shandong Province, and to provide data evidence for taking intervention measures. Methods From 2011 to 2013, 1 - 3 samples of drinking water were collected from all administrative villages in 8 counties (cities and districts) of Liaocheng.At the same time,1 sample of edible salt was collected from the household where water samples were collected. Arsenic and cerium spectrophotometry was used for the detection of water iodine and salt iodine was detected by semi-quantitative method. The region were divide according to the definition of "Water Source Excess Iodine Area and Excess Iodine Disease Area"(GB/T 19380-2016)and"Division of Iodine Deficiency Disorders Area"(GB 16005-2009).Results A total of 7 794 water samples were collected in 5 865 villages of 134 towns and the iodine median was 158.2 μg/L. The median of water iodine of 57 samples was less than 10 μg/L in drinking water and the ratio was 0.7%;2 286 samples were 10- 100 μg/L and the ratio was 29.3%; 5 451 samples were over 100 μg/L and the ratio was 69.9%. The towns with suitable water iodine (10 - 100 μg/L) and high water iodine ( > 100 μg/L) were 24.6%(33/134)and 75.4%(101/134), respectively, and no iodine deficiency town was found. The areas with high water iodine were distributed in patchy or foci. A total of 3 300 salt samples were collected,among them,iodized salt was 1 183(35.58%,1 183/3 300)and non-iodized salt was 2 117(64.15%,2 117/3 300). Among them, there were 36 towns with high iodine content and 20 towns with suitable iodine content, and the iodized salt coverage rates were 10.72% (225/2 099) and 79.77% (958/1 201),respectively.Conclusions The population of Liaocheng City is at risk of iodine excess.The high iodine areas coexists with suitable iodine areas.
ABSTRACT
Objective To investigate the value of partial hepatectomy in the treatment of hilar cholangiocarcinama( HCC). Methods In this report, 42 patients with hilar cholangiocacinoma treated surgically were analyzed retrospectively. Results Of the 42 patients, 34 cases (81%) underwent surgical resection. In these 34 cases, 15 cases were treated by local resection, 8 cases by a combination of right lobectomy, 3 cases by left lobectomy, 4 cases by left lobectomy and caudate lobectomy, 1 case by left lateral lobectomy and caudate lobectomy, 3 cases by quadrate lobectomy. Curative resection was performed in 25 patients. The median survival rate in patients with curative resection was 28 months, while that with palliative operation was 14 months. The 1-, 2-, and 4-year survival rates of curative resection were 90% , 73% , and 28% , respectively. The 1-, and 2-year survival rates of palliative operation were 57% , and 27%. Conclusion Survival rates in patients with curative resection were better than that of palliative operation. Radical resection in many cases demands a combined liver resection.
