Objective To study the relationship between serum leptin and thyroid function by investigating the change of serum leptin concentration in children with abnormal thyroid function (hyperthyroidism and hypothyroidism).Methods The levels of serum leptin was determined by radio-immunoassay(RIA) in 20 cases of hyperthyroidism, 17 cases of hypothyroidism, 25 cases of normal controls, respectively .Meanwhile, the serum levels of free triiodothyronine(FT 3), free thyroxine(FT 4) and thyroid-stimulating hormone(TSH) were measured by micro-particle-chemiluminescence immunoassay.Results The levels of serum leptin in hypothyroidism group before treatment was significantly lower than that of normal control groups (P0.05).Conclusions The levels of serum leptin in hypothyroidism markedly descend and no change in the hyperthyroidism. Thyroid hormone can promote the secretion of serum leptin eligibly.

Objective To study the early therapeutic principle of severe acute pancreatitis(SAP)complicated with intra-abdominal hypertension(IAH).Methods We reviewed 32 cases SAP complicated with IAH from January 2003 to January 2008 in our department.All cases' clinical features and early management were summarized.Results The intra-abdominal pressure of all the cases was above 15cmH2O.5 deaths occured in non-operation treated cases,6 deaths in the 11 operated cases,and all the dead cases reached the standard of ACS.Conclusions The uses of early individualized treatment can decrease the opportunity of decompressive operation,we can effectively improve the therapeutic effect of SAP complicated with IAH and reduce the probability of complicating with ACS.

AIM: To study the protection of extract of Radix Atragali composite against acute hepatic injury. METHODS: Fed with the extract of Radix Atragali composite, m ice were injected with D-galactosamine intraperitoneally (800 mg/kg) and rats were i njected with carbon tetrachloride hypodermically (5 mL/kg) to induce acute hepat ic injury on the 8th day. ALT, AST and bilirubin in serum were examined. Patholo gical changes of liver tissue were observed. RESULTS: Compared with model group, activities of ALT and AST, c oncentrations of bilirubin were markedly decreased and pathological scores also showed that degeneration and necrosis of hepatic cell were lighter in the the ex tract of Radix Atragali composite treatment group. CONCLUSION: The extract of Radix Atragali composite attenuat es hepatic injury induced by D-galactosamine or carbon tetrachloride.

Objective To investigate the prevalence and frequency of the common mutations in Uigur non-syndromic deafness group in Xinjiang Uigur Autonomous Region of China, by means of screening nine mutations of four known deafness genes. Methods One hundred eighty-four Uigur patients and 133 Han patients with non-syndromic hearing loss were enrolled in this study. The screening was performed on GJB2, GJB3, mtDNA 12S rRNA and SLC26A4 deafness genes of 35delG, 176de116,235de1C ,299-300delAT,538C ＞ T, 1555A ＞ G, 1494C ＞ T,2168A ＞ G, IVS7-2A ＞ G in these two groups, by means of genic microarray. Results The totlal mutation rate found in the Uigur deafness groups was 12. 50%, significantly different from that in the Han deafness groups (30. 83% ,χ2 = 16. 092 ,P ＜0. 01 ). The GJB2 mutation rate in the Uigur deafness groups was 9. 24%, not significantly different from that in the Han deafness groups ( 14. 29% ,χ2 = 1. 953 ,P ＞0. 05 ). The mutation rate of SL C26A4 was 1.63% and 13.53% respectively in Uigur and Han deafness groups, and has significant difference (χ2 = 17. 683, P ＜ 0. 01 ). The mt DNA 12S rRNA mutation rate in the Uigur deafness groups was 1.63%, not significantly different from that in the Han deafness groups (3.01%, χ2 = 0. 175, P ＞ 0. 05 ). The GJB3 mutation rate of these two deafness groups was very low, shown as 0. 75% and 0 respectively. Conclusions The mutation rate of common deafness genes is lower in the Uigar nonsyndromie deafness group, and the mutation rate of SLC26A4 genes is significantly lower than that in the Han deafness groups. The most common mutation in four known deafness genes is GJB2, whose favorite spots are 235delC and 35delG.

Objective To analyze the levels and speciation of arsenic metabolites in urine of rats treated with sodium arsenite and sodium arsenate in order to investigate the different aspects of metabolism between sodium arsenite and sodium arsenate,thus to understand further the basic data about relationship between it's metabolism and mechanism of toxicity. Methods Seventy Wistar rats,weighting 80-120 g,were divided into 7 groups of 10 each,such as normal control group,high,middle and low sodium arsenite group and high,middle and low sodium arsenate group. After the animals were fed for one month,the urine was collected by metabolic cage in 12 hours. Applying the high efficiency liquid chromatography and hydride genesis atomic fluorescence spectroscopy (HPLC-HGAFS),the levels and speciation of arsenic metabolites were determined in urine of rats. Meanwhile,the recovery rate of dimethyl arsinic acid(DMA) would be determined to estimate the degree of accuracy of results. Results The levels of iAs~(3+),iAs~(5+) and DMA in middle sodium arsenite group[(121.66±1.26),(10.26±2.68),(200.91±0.56) μg/L]were higher than the high sodium arsenite group[(113.20±0.75),(5.16±1.32),(147.70±μ0.77)μg/L,all P < 0.05]and low sodium arsenite group[(79.35±2.12),(5.13±2.25),(56.35±1.23)μg/L,all P < 0.05]. The levels of iAs~(3+) and DMA in middle sodium arsenate group[(315.81±1.69),(245.12±1.18)μg/L]were higher than the high sodium arsenate group[(85.03±0.56),(110.34±1.04)μg/L,all P< 0.05]and low sodium arsenate group[(22.97±2.67),(15.75±2.15)μg/L,all P < 0.05]. Compared with sodium arsenate group,the levels of iAs~(3+) and DMA in high and low sodium arsenite group were higher(all P < 0.05) ; and the levels of iAs~(3+) and DMA in middle sodium arsenite group were lower(all P < 0.05). Meanwhile,the average urinary recovery rate of DMA of rats in different sodium arsenite group were 94.80%-102.70%,and the average urinary recovery rate of DMA of rats in different sodium arsenate group were 95.33%-108.40%. Conclusion The speciation and levels of arsenic are influenced by the external exposure dose,and some distinction appeared in the metabolism and metabolic path between sodium arsenite and sodium arsenate in urine in vivo.
