Objective To study the significance of thyroid stimulating antibody (TSAb) and thyroid stimulating-blocking antibody (TSBAb) in children with Graves' disease (GD) or Hashimoto's thyroiditis (HT).Methods Five hundred and twenty-seven cases of serum from 180 children with autoimmune thyroid disease (AITD) children were divided into 282 cases of GD and 245 cases of HT.According to the status of thyroid function,they were divided into 157 cases of hyperthyroidism,91 cases of hypothyroidism and 279 cases of normal thyroid.GD group was subdivided into 127 GD hyperthyroidism and 155 GD remission;HT group was subdivided 30 HT hyperthyroidism,124 HT remission and 91 HT hypothyroidism.Seventy-nine healthy children were taken as the healthy control group.Free triiodothyronine(FT3),free thyroxine(FT4) and sensitive thyroid stimulating hormone(TSH) were detected by chemoluminescence.Serum TSAb and TSBAb were detected by serum TSAb or TSBAb enzyme linked immunosorbent assay (ELISA),respectively.The differences in TSAb and TSBAb among each group were compared and analyzed of find out the relationship between TSAb and TSBAb was performed.Beside,the correlation between TSAb and TSBAb with FT3,FT4,and TSH were analyzed.Results (1) TSAb levels were significant (F =11.995,all P =0.000):the GD group (0.727 ± 0.157) ＞ HT group (0.605 ± 0.148) ＞ healthy control group (0.350 ± 0.105);the difference was significant(F =109.165,P =0.000) among hyperthyroidism group (0.745 ± 0.169) ＞ normal thyroid group (0.647 ± 0.153) ＞hypothyroidism group(0.612 ±0.144) ＞healthy control group (0.350 ±0.105);the difference was significant(F=156.712,P =0.000) in the GD hyperthyroidism group(0.747 ±0.17) ＞ GD remission group (0.640 ± 0.16) ＞ healthy control group (0.350 ± 0.105);the difference was significant (F =109.165,P =0.000) in the HT hyperthyroidism group(0.739 ±0.140) ＞HT remission group(0.655 ±0.135) ＞ HT hypothyroidism group(0.612 ± 0.140) ＞healthy control group (0.350 ±0.105).(2) TSBAb levels were significantly different(F =15.610,P =0.000):the HT group(0.704 ±0.633) ＞ GD group(0.567 ±0.178) ＞ healthy control group (0.334 ±0.104);the difference was significant(F =13.311,P =0.000) in the hypothyroidism group (0.693 ± 0.125) ＞ remission group (0.648 ±0.446) ＞hyperthyroidism group(0.562 ±0.181) ＞healthy control group(0.334 ±0.104);the difference was significant(F =19.269,P =0.000) in the GD remission group (0.672 ±0.572) ＞ GD hyperthyroidism group (0.550 ± 0.187) ＞ healthy control group (0.334 ± 0.104);HT hypothyroidism group (0.693 ± 0.725) was higher than HT hyperthyroidism group(0.618 ±0.142) and HT remission group (0.619 ±0.199),the difference was not significant between HT hyperthyroidism group and HT remission group(F =12.208,P =0.000).(3) TSAb level was positively correlated with TSBAb,FT3 and FT4(r =0.162,0.091,0.194,all P ＜ 0.05) and was negatively correlated with TSH (r =-0.224,P ＜ 0.05).TSBAb levels were negatively correlated with FT3 (r =-0.155,P ＜ 0.05) and was positively correlated with TSH (r =0.131,P ＜ 0.05).Conclusions Thyroid function was related to the serum levels of TSAb and TSBAb.TSAb and TSBAb could be regarded as an important predictive index for children with AITD during the treatment period.

Background and purpose:Osteopontin (OPN) is a secreted glyco-phosphoprotein, which is overex-pressed by numerous human cancers, invovled in tumor occurrence, development and prognosis. OPN up-regulates matrix metal proteases (MMPs) expression in a NF-κB-dependent fashion during extracellular matrix (ECM) invasion causing degradation of cell basement membrane and ECM leading to tumor invasion and metastasis. The aim of this study was to examine the protein level of OPN in a large number of tissue samples from patients with lung squamous cell carcinoma (SCC), and evaluate its potential clinical value.Methods:The OPN protein levels in 265 tumor tissue samples and corresponding 24 normal lung tissue samples were examined by immunohistochemical (IHC) analysis.Results:IHC results showed that the positive rate of OPN was 64.5% in the SCC tissues, which was significantly higher than that in normal alveoli tissues (29.2%,P<0.001). The positive rate of OPN expression in late stage (Ⅲ+Ⅳ) tissues was 78.4%, significantly higher than that in early stage (Ⅰ+Ⅱ) tissue(positive rate 54.5%,P<0.001). The positive rate of OPN expression in T3-4 stage (Ⅲ+Ⅳ) tissue was 76.9%, significantly higher than that in T1-2 stage tissue (positive rate 59.4%,P=0.007). The expression of OPN was signifcantly correlated with the status of lymph node metastasis (LNM). The positive rate in the tumor tissue with LNM was 73.4%, significantly higher than that without (positive rate 51.4%,P<0.001).Conclusion:The level of OPN protein was overexpressed in lung cancer tissues, involved in SCC carcinogenesis and LNM. It is indicated that OPN has an impor-tant reference value in diagnosis, prognosis and therapy of SCC.

Objective To investigate the difference in cardiac structure and hemodynamics characteristics between fetuses with isolated persistent left superior vena cava (LSVC)and normal fetuses by using fetal echocardiography,in order to explore whether isolated PLSVC has some influence on the development of fetal heart structure development.Methods Twenty-two fetuses diagnosed with isolated PLSVC in the second and third trimester were enrolled in this study.The PLSVC fetuses were divided into two groups:group 1 ,twenty-two fetuses in the second trimester (23-27+6 W);group 2,twenty fetuses in the third trimester (28-39+6 W).Forty-nine fetuses without intra-cardiac and extra-cardiac anomalies with gestation age matched were involved as normal control groups:25 fetuses in the second trimester,and 24 fetuses in the third trimester.The parameters of cardiac structure and hemodynamics of the four groups were measured,including left and right sideheart size,the diameter of foramen ovale(FO),aorta(AO),aortic isthmus and pulmonary artery (PA).The ratio of RV/LV,RA/LA and PA/AO were calculated.The hemodynamic parameters included the flow velocity across mitral valve(MV),tricuspid valve(TV)and FO. All the parameters of PLSVC groups were compared with the normal groups respectively.Results In the second trimester group,the ratio of RV/LV and PA/AO of the PLSVC fetuses were significantly larger than normal,while the AO diameter,aortic isthmus diameter were smaller than normal group (P <0.05). However in the third trimester group,only the ratio of PA/AO of the PLSVC group was significantly greater,and the aortic isthmus diameter was still smaller than the normal group (P <0.05).Conclusions Isolated PLSVC connected with coronary sinus is associated with structural differences from normal.A dilated coronary sinus may have an influence on the development of fetal left heart structures.

Hepatolithiasis is a common disease of abdominal surgery,although its incidence appears to decline,China is still a high incidence area with millions of patients with hepatolithiasis.Because of the complex pathogenesis,progressive development and frequent recurrence,it is seriously affecting physical and mental health of patients and quality of life,as well as difficult to define the diagnosis and select treatment methods for hepatolithiasis.The Guideline of the Diagnosis and Treatments of Hepatolithiasis and the Expert Consensus of the Laparoscopic Treatments of Hepatolithiasis (2013 edition) proposed a concise and practical classification system of the hepatolithiasis and summarized the principles of surgical treatments,which includedresecting the lesions,cleaning the stones,correcting the stricture,recovering the drainage and preventing the recurrence .Meanwhile,the application of laparoscopic technique in the treatments of bepatolithiasis was proposed,which played an important role to promote the standard diagnosis and treatments of hepatolithiasis in China.Recent years,more and more evidences from evidence-based medicine further proved the importance of the anatomical hepatectomy in the treatments of hepatolithiasis.With the soaring development of laparoscopic surgery,the combination of laparoscopic hepatectomy with the assistance of other endoscopies are applied more and more frequently.The concept of precise surgery also brings new vitality to the standard diagnosis and treatments of the hepatolithiasis.

Objective:To analysis the N-terminal amino acid sequence of 5D3Ag purified by mAb5D3 immunoaffinity column.Methods:SDS-PAGE and Western Blot were used to study the characteristics of 5D3Ag.From SDS-PAGE gel,5D3Ag was transferred to PVDF membrane and its N-terminal amino acid sequence was analysised with an auto amino acid sequencer.Results:SDS-PAGE of 5D3Ag showed a band on the gel with molecular weight of 43 kD.Western Blot study showed that mAb5D3 can recognize 5D3Ag.The N-terminal amino acid sequence was NQGSHGSEEQ.Conclusion:It is sure that 5D3Ag is unique to Osteosarcoma because of the purification method itself and the characteristics of mAb5D3.Compared with other reported Osteosarcoma associated antigen,5D3Ag is different from them in molecular weight and may be a novel Osteosarcoma associated antigen.With the help of N-teminal amino acid sequence,some primers may be designed to clone the whole length gene of 5D3Ag.The identification of 5D3Ag gene may be useful in understanding the biologic mechanics of Osteosarcoma and developing new diagnostic and therapeutic strategies.
