Objective To observe the activities of serum peroxidase capacity,and lipid peroxidation of children from Kaschin-Beck disease (KBD) areas of Xinghai county in Qinhai province,and to explore the relationship between antioxidant capacity and KBD.Methods Sixty four KBD and forty six health subjects without KBD were chosen from KBD endemic areas,which included primary schools of Tangnaihai,Xialujuan and Qushian of Xinghai county in Qinghai province,and fifty nine age-matched healthy control subjects without KBD were from a non-KBD endemic area,Nanfan primary school of Chang'an county in Shaanxi province.Twenty patients with KBD and twenty control subjects from KBD areas and non-KBD area were extracted by simple random sampling method.2,3-DAN fluorescence technique was used to test the hair and blood selenium.The biochemical techniques were used to test the indicators of oxidative stress including malondialdehyde(MDA),antioxidant enzyme activities,total antioxidant capacity(T-AOC),serum superoxide dismutase(SOD),catalase(CAT) and glutathione peroxidase(GSHPx).ResultsAll patients with KBD had significantly lower serum GSH-Px activities[ (59.53 ± 25.23)kU/L] and selenium levels in hair[ (67.64 ± 17.28)μg/L] and blood[(36.27 ± 13.29)μg/L],respectively,than that of control subjects from KBD areas [ ( 91.88 ± 22.99 ) kU/L,( 153.32 ± 24.31 ) μg/L,( 63.06 ± 13.66) μg/L ] and nonKBD areas[ ( 122.68 ± 41.74)kU/L,(242.35 ± 38.56)μg/L,(98.93 ± 17.18)μg/L,all P ＜ 0.05].Serum MDA levels in KBD patients[ (4.64 ± 1.11 )μmol/L] were significantly higher than that in control subjects from KBD [(3.31 ± 1.22)μmol/L] and non-KBD areas[ (3.43 ± 1.29)μmol/L,all P ＜ 0.05].On the other hand,T-AOC,SOD and CAT activities were significantly higher in both KBD[(19.80 ± 6.64),(55.80 ± 8.14),(16.45 ± 5.61 ) kU/L] and control subjects[ (21.71 ± 8.82),(57.45 ± 6.96),(15.63 ± 9.18)kU/L] from KBD areas than that of control subjects from non-KBD area[ (13.56 ± 5.38),(42.79 ± 8.10),(6.05 ± 2.71 )kU/L,all P ＜ 0.05 ].Hair selenium levels,blood selenium levels and GSH-Px activity of control subjects from KBD areas were,respectively,significantly lower than that in control subjects from non-KBD area(all P ＜ 0.05).Conclusions These findings strongly confirm the evidence that KBD patients are susceptible to oxidative stress.The results also show the increase in antioxidant enzymes,which could probably be due to adaptive response to pro-oxidant in KBD state.Hence,there seems to be an imbalance between oxidant and antioxidant systems in KBD patients.

Objective To investigate the value of ratio of luteinizing hormone (LH) to folliclestimulating hormone (FSH) in diagnosis of polycystic ovarian syndrome (PCOS) among women with ploycystic ovary (PCO) and to compare the difference of the diagnostic criteria between the Rotterdam Consensus and the Committee for Reproductive and Endocrine in Japan Society of Obstetrics and Gynecology.Methods By means of transvaginal Doppler ultrasound, 195 women with PCO were diagnosed in Nanfang Hospital of Reproductive Medicine Center and compare difference of multiple clinical indexes according to Rotterdam consensus and Japan consensus respectively. In the mean time, the ratio of LH/FSH, the level of LH, testosterone (T) and recevier operating characteristic (ROC) curve were explored to on the value of diagnosis of PCOS. Results By Rotterdam consensus, 144 women were diagnosed with PCOS and 51 women were non-PCOS, while 111 were identified as PCOS and 84 were non-PCOS according to Japan consensus. LH/FSH in PCOS and non-PCOS were 1.59 ±0. 84 and 0. 85 ±0. 47 respectively when based on Rotterdam consensus, and this ratio were 1.87 ± 0. 76 in PCOS and 0. 78 ± 0. 39 in non-PCOS based on Japan consensus. When using LH/FSH to diagnosis PCOS by Rotterdam consensus and Japan consensus,areas under ROC curve are 0. 786 and 0. 942, respectively. Conclusions The ratio of LH/FSH ≥ 1 provide the significant value in the diagnosis of PCOS. The criteria of the Committee for Reproductive and Endocrine in Japan Society of Obstetrics and Gynecology is more suitable for Chinese patients.

Hashimoto's encephalopathy(steroid-responsive encephalopathy associated with autoimmune thyroiditis,SREAT)is a rare disorder,accompanied by seizures,tremor,myoclonus,ataxia,psychosis,and stroke-like episodes,breaking out with an acute or subacute onset and having a relapsing/remitting or progressive course which is not correlated to thyroid hormone levels.Patients with Hashimoto's encephalopathy are usually euthyroid or dysthyroid with positive antithyroid antibodies,have a moderately raised cerebrospinal fluid protein content,and have a global slowing of the electroencephalogram and a normal or near normal imaging except in rare cases.The pathogenesis of Hashimoto's encephalopathy is still obscure.This paper reports a case diagnosed as"Hashimoto's encephalopathy".It is suggested that the diagnosis of Hashimoto's encephalopathy should be considered in cases with unexplained encephalopathy associated with high levels of antithyroid antibodies despite normal thyroid function.

Objective To find out the arsenic pollution in Yangzonghai lake and its influence to the surrounding drinking water source and the local food and to provide a scientific basis for arsenic pollution control,drinking water and food safety. Methods Arsenic monitoring were carried out in 10 points of Yangzonghai lake,45 water sources within 5 km of Yangzonghai lake, and locally produced food. Results From September 2008 to December 2009, the water arsenic concentrations of Yangzonghai lake ranged 0.06 - 0.18 mg/L, the average arsenic concentrations were 0.12 mg/L and 0.10 mg/L for 2008 and 2009, respectively, the value of 2009 was higher, and the difference was statistically significant(t = 3.284, P ＜ 0.05). There were no significant difference in the average of arsenic concentration of Yangzonghai lake between the dry and rainy season in 2009(t = 0.905, P ＞0.05). The arsenic concentrations from the No. 3 spring water ranged from 0.12 - 30.36 mg/L. After a peak value early in October 2008, the No. 3 spring water showed a downward trend month by month. In 2008 the average arsenic concentration was 23.92 mg/L, 2009 was 2.41 mg/L, down 89.92% over the previous year, the difference was statistically significant(t = 9.582, P ＜ 0.05 ). In January and February 2009, the average arsenic concentration (11.96 mg/L) was significantly higher than those of March-December(0.50 mg/L, t = 57.759, P＜ 0.05). In Yangzong town, the arsenic concentration in the drinking water and river met the national drinking water health standards. Among 78 samples monitored of the locally produced food in Yangzong town, 77 passed, with a pass rate of 98.72%. Conclusions Arsenic contamination has been effectively controlled. The drinking water and local food production has not been contaminated by arsenic except aquatic products in Yangzonghai Lake. It is recommended to take effective measures to prevent water contamination.

OBJECTIVETo assess the feasibility and safety of radiofrequency ablation (RFA) in spleen to treat secondary splenomegaly and hypersplenism in dogs.

METHODSFourteen healthy mongrel dogs were randomly divided into two groups: group A (n = 4) and group B (n = 10) Both groups underwent ligation of the splenic vein and its collateral branches to induce congestive splenomegaly. At the end of the 3rd week, radiofrequency thermal ablation of the spleen was performed in the group B via laparotomy. After splenic RFA, the procedure-related complications were observed, CT scan was performed and the spleens were obtained according to schedule. The radiofrequency (RF) thermal lesions and its histo- pathological changes of the spleen were examined regularly.

RESULTSThere were no morbidity and mortality in the experimental dogs. CT findings revealed that splenomegaly could sustained over 2 months after ligation of the splenic vein. The segmental RF lesions included hyperintense zone of coagulative necrosis and more extensively peripheral hypo-intense infarcted zone. The latter was called as "bystander effect". The infarcted zone would be absorbed and subsequently disappeared between 4 and 6 weeks after RFA, and the size of the remnant spleen shrunk, but the lesion of coagulative necrosis hardly altered. The fundamental histopathological changes of splenic lesions caused by RF thermal energy included local coagulative necrosis and the peripheral thrombotic infarction zone. Subsequently, tissue absorption and fibrosis occurred in the zone of thrombotic infarction. Simultaneously occluded vessels, fibrin deposition, and disappearance of normal splenic sinuses resulted in the condensed structure of the viable remnant spleen, which were the pathological basis responsible for the shrunk spleen.

CONCLUSIONSIt is feasible and safe to perform RFA in the spleen to treat experimental splenomegaly and hypersplenism. The RFA technique could be safely performed clinically via laparotomy or laparoscopic procedure to strictly isolate the spleen from the surrounding organs.
