Objective To observe the changes of hospitalization rates of patients with goiter in Lianyungang City in a coastal area with mild iodine deficiency in 2002-2010.Methods Medical reports of patients with goiter from county hospitals were studied at county level with a retrospective method.In accordance with the National Iodized Salt Monitoring Program,nine townships(towns) were taken from each county (district) [total of five counties(districts)]; four villages were selected from each township (town); salt samples were taken from eight households in each village,and salt iodine was determined using direct titration of sodium thiosulfate.Results The hospitalization rate of patient with goiter increased from 1.87/10 million in 2002 to 7.05/10 million in 2009,and then fluctuated to 6.06/10 million in 2010(x2 =281.91,P< 0.01).Among them,female's hospitalization rates were significantly higher than that of male 's(The variation range of x2 values were 35.23-116.04,all P < 0.01),and the hospitalization rates of people over the age of 40 years were significantly higher than that of people less than 40 years of age(The variation range of x2 values were 33.04-263.04,all P < 0.01),and the hospitalization rates of people in urban areas were significantly higher than that of people in rural areas (The variation range of x2 values were 18.35-140.00,all P < 0.01).Average salt iodine was 27.61-30.13 mg/kg in 2002-2010.The coverage rate of iodized salt and the consumption rate of qualified iodized salt both increased year by year (x2 =183.75,211.99,P < 0.01).There was a positive correlation between hospitalization rate of patient with goiter and coverage rate of iodized salt(spearman correlation coefficient was 0.83,P < 0.05).There was a positive correlation between hospitalization rate of patient with goiter and the consumption rate of qualified iodized salt too (spearman correlation coefficient was 0.93,P < 0.05).Conclusions In Lianyungang City,the hospitalization rate of patient with goiter,the coverage rate of iodized salt and the consumption rate of qualified iodized salt all show upward trend in 2002-2010.The relationship among them is worth further study.

Abstract: Suxamethonium chloride is a depolarizing muscle relaxant used in general anesthesia. In overdose, it causes adverse reactions such as bradycardia, arrhythmia, cardiac arrest, and death. The article reviews the progress on testing methods of suxamethonium chloride such as infrared spectroscopy, chemical color reaction, chemical titration, enzyme electrode, chromatography and mass spectrometry.

T mutation was detected in the 4th propositus at the 9th intron,but any COL1A1 or COL1A2 gene mutation was detected in the third propositus and the other members in the former families.Conclusions The genetic mutation of COL1A1 may result in OI in China,but other mutations may also exist.Moreover,the phenotype was influenced not only by OI genotype,but also by the genetic background,environment and other factors.

Objective: To investigate the mechanisms of electroacupuncture (EA) at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) in intervening diabetic gastroparesis (DGP) based on calcium-activated chloride channel. Methods: Forty Sprague-Dawley rats were randomly divided into four groups, including a normal control group (group A), a model group (group B), an EA group (group C) and a metoclopramide group (group D), with 10 rats in each group. A single intraperitoneal injection of 2% streptozotocin (STZ) combined with 8-week high-glucose high-fat diet was used to establish a DGP rat model. After intervention, gastrointestinal propulsive rate was observed; the expression level of transmembrane protein 16A (TMEM16A) was examined by immunohistochemistry; the Ca2+ concentration in interstitial cells of Cajal (ICCs) was detected by immunofluorescence; and whole-cell patch-clamp technique was applied to detect the current intensity of calcium-activated chloride channel (ICaCC) in ICCs in gastric antrum. Results: After modeling, the blood glucose levels in group B, group C and group D were significantly increased compared with group A (all P<0.01); after intervention, compared with group B, the blood glucose levels in group C and group D were significantly decreased (P<0.05, P<0.01); the intra-group comparison of blood glucose level between after modeling and after intervention found significant difference only in group C (P<0.01). The gastrointestinal propulsive rates in group B, group C and group D were significantly different from that in group A (P<0.01 or P<0.05); the gastrointestinal propulsive rates were markedly higher in group C and group D than in group B (P<0.01, P<0.01). The expressions of TMEM16A in group B and group C were decreased compared with group A (P<0.01, P<0.05); the expressions of TMEM16A in group C and group D were increased compared with group B (P<0.01, P<0.05). The fluorescence intensity of Ca2+ was significantly lower in group B than in group A (P<0.01); the fluorescence intensity of Ca2+ was significantly higher in group C and group D than in group B (P<0.01, P<0.05). ICaCC in ICCs in group B was significantly decreased compared with group A; ICaCC in group C and group D were increased compared with group B. Conclusion: EA at Zusanli (ST 36), Liangmen (ST 21) and Sanyinjiao (SP 6) can significantly improve gastrointestinal motility in DGP rats by up-regulating the ICaCC in ICCs.

Objective To study investigate the dose accuracy that can be achieved with the method of bulk density assignment.Methods Sixteen cases of nasopharyngeal cancer patients and nineteen cases of esophageal cancer patients who accept radiotherapy in our department were selected.The planning CT images with bulk density assignment to different classes of tissues were applied to calculate the dose distributions,and then the resulting dose volume histograms (DVH) of the tumor and organs of risk were compared with the original treatment plan.The paired t-test was taken for dose comparison between two plans.Results The DVH comparison based on the planning CT and the bulk density assignment CT showed good agreements.With nasopharyngeal cancer patients,differences between the two plans about target and normal tissue were less than 1%.With esophageal cancer patients,the dose differences were less than 2%.Conclusion Preliminary results confirm that the bulk density assignment method can be applied to calculate the dose distributions.
