Thyroid peroxidase (TPO) , originally described as thyroid microsomal antigen, is present on the apical surface of thyroid follicular cells and is an antigen involved in cell mediated cytotoxicity. TPO evokes high-affinity, IgG-class autoantibodies (TPOAbs) and TPO-specific T cells that are markers of thyroid infiltration or implicated in thyroid destruction, respectively. Enzyme-linked immunosorbent assay is used most frequently for TPOAb detection and quantification. The other conditions associated with TPOAbs include pernicious anemia, connective tissue disorders, diabetes, inflammatory bowel disease, mood disorders, and fertility-related problems such as miscarriage, infertility, in vitro fertilization failure, pre-term delivery, and postpartum thyroiditis. The detection of TPOAhs is recommended in the investigation of goitre, diagnosis of Graves' disease and Hashimoto's thyroiditis, and the prediction of risk of developing hypothyroidism during subclinical thyroid disease.

Objective To investigate the feasibility of video-assisted thoracoscopic surgery (VATS) for treating spontaneous chylothorax. Methods Four patients with spontaneous chylothorax were treated by VATS from April 2000 to October 2003. Results Operations were successfully completed in all the 4 patients. The operative time was 40, 52, 55, and 95 min, respectively (mean, 60.5 min). The postoperative chest drainage time was 3~8 d (mean, 5.2 d). The postoperative hospital stay was 8~13 d (mean, 10.5 d). No severe complications or operative mortality were seen. Conclusions Treatment of spontaneous chylothorax by VATS gives advantages of less invasion and quick recovery.

Objective To explore the feasibility and value of special carotid cavemous fistula(CCF). Metheds In 28 cases with traumatic history, cerebral angiographies were performed via percutaneous transfemoral route before endovascular embolization. Results Bilateral CCF in 6 cases,unilateral CCFs including mutileakage in 2 cases and small fistulae in 4 cases,CCF combined with fracture segment in 11 cases,traumatic aneurysms in 3 cases,NPPB after embolizationin 2 cases. The fistulas of 9 cases were occluded with patency of internal carotid artery(ICA),and ICA were occluded in 19cases.Conclusions Endovascular embolization of carotid cavernous fistula was safe and effective.This methed should be the first choice for the treatment.Different techniques of endovascular embolization should be undertaken for different CCF.

There are many subjects related to anesthesiology and the band between anesthesiology and clinical practicevery is close. So students can not be proficient in anesthesiology by traditional teaching methods. The use of three-dimensional case teaching method in anaesthesiology teaching is a good attemptment. three-dimensional case teaching method integrate case method, multimedia technology and clinical case. It can help medical students analyze and solve clinical problems, improvetheir academic performance and enhance their clinical basic skills.

score, prostate volume and peak urinary flow rate, correlate with BPH, but not with nocturia. Keeping a detailed urinary diary for the patients is beneficial for elucidating their urinary function and in decision-making of their treatment regimen.

OBJECTIVE:To observe the effects of different routes of administration of tranexamic acid on coagulation function and amount of bleeding in patients with one stage posterior surgery of thoracic tuberculosis. METHODS:40 patients suffered from thoracic tuberculosis in our hospital from Jan. 2011 to Dec. 2013 were randomly divided into intravenous group(5% Glucose injec-tion 100 ml+tranexamic acid 10 mg/kg,through an intravenous drip at 30 min before closing the wound) and topical application group(5% Glucose injection 10 ml and tranexamic acid 10 mg/kg,through soaking the wound before closing the wound)with 20 cases in each group. Other 15 cases suffered from the thoracic tuberculosis in our hospital from Jan. 2009 to Dec. 2010 were includ-ed in control group. 3 groups received one stage posterior surgery of thoracic tuberculosis,interbody fusion and internal fixation. The difference of hemoglobin,coagulation function and the amount of suction drainage were observed before and after surgery, and followed up. Bone graft fusion and therapeutic condition of tuberculosis were observed in the study. RESULTS:There was no statistical significance in postoperative suction drainage between intravenous group and topical application group (P>0.05),but their decrease was more significant than control group,with statistical significance(P<0.05). There was no statistically difference in fiber protease,prothrombin time or activated partial thromboplastin time among 3 groups(P>0.05). The difference value of he-moglobin in control group before and after operation was significantly higher than in intravenous group and topical application group,with statistical significance (P<0.05);there was no statistical significance between intravenous group and topical applica-tion group(P>0.05). 55 patients were all followed up and bone graft of all cases were fused,and all patients were cured and no case recurred. CONCLUSIONS:Tranexamic acid by intravenous application or topical application can reduce hemorrhage and ane-mia after operation of thoracic tuberculosis,and has no effect on blood coagulative system.

AIM: To explore the effect of bone marrow-derived mesenchymal stem cells (BMSCs) combined with vitamin E on the inflammatory reaction in acute kidney injury ( AKI) rats.METHODS:Gentamicin was used to in-duce AKI and the rats were treated with BMSCs combined with vitamin E.After treatment, the rat plasma and kidney tis-sues were collected, and the expression of inflammatory factors at mRNA and protein levels was detected by real-time quan-titative PCR and ELISA.RESULTS:After the treatment with BMSCs combined with vitamin E, the inflammatory proteins were down-regulated in the plasma and the renal tissues.Compared with single treatment group, the decreases in the in-flammatory proteins were more obvious in combined treatment group.CONCLUSION: The method of BMSCs combined with vitamin E takes the anti-inflammatory effect on AKI, indicating a new and potential mode in clinical application for AKI therapy.

Objective To investigate the effect of propofol anesthesia on electroconvulsive therapy (ECT)-induced hyperphosphorylation of Tau protein in hippocampus in depressed rats.Methods Thirty-two female WYK rats in which the total score was 30-120 after Open-field test,aged 24 weeks,weighing 200-250 g,were randomly divided into 4 groups ( n =8 each):control group (group C),propofol group (group P),ECT group (group E)and propofol + ECT group (group PE).In groups C and E,the animals received intraperitoneal normal saline 5 ml,and in addition the animals received ECT 15 min later in group E.In groups P and PE,the animals received intraperitoneal 100 mg/kg propofol 5 ml,and in addition the animals received ECT 15 min later in group PE.The learning and memory function was assessed by Morris water maze test at 24 h after ECT.The animals were sacririced at 6 h after Morris water maze test and the hippocampal tissues were removed for determination of the expression of phosphorylated Tau protein.Results Compared with group C,the escape latency was significantly prolonged,the swimming time was significantly shortened in groups P,E and PE,the expression of phosphorylated Tau protein in hippocampus was down-regulated in group P,and the expression of phosphorylated Tau protein in hippocampus was up-regulated in group E ( P ＜ 0.05).Compared with group E,the escape latency was significantly shortened,the swimming time was significantly prolonged,and the expression of phosphorylated Tau protein in hippocampus was down-regulated in group PE (P ＜0.05).Conclusion The mechanism by which propofol anesthesia improves cognitive impairment induced by ECT may be related to inhibition of hyperphosphorylation of Tau protein in hippocampus in depressed rats.

Hepatic fibrosis models were induced by CCl4 in rats. To explore vascular endothelial growth factor (VEGF), transforming growth factor-beta1 (TGFβ1) mRNA expression and bcl-2, Bax protein expression levels of intervention and explore the mechanism of the Aralia chinesis anti-hepatic fibrosis. Sixty male Sprague-Dawlley (SD) rats were randomly divided into six groups: nomal group, model group, high-dose (10 mL x kg(-1)), medium-dose (7.5 mL x kg(-1)), low-dose (5.0 mL x kg(-1)) of A. chinesis treated group and colchicine treated group. The change of liver histopathology was observed by HE and Masson staining. The mRNA of VEGF, TGF-β1 were detected by RT-PCR. The protein of Bcl-2 and Bax were detected by Western blot. In the model group liver cell obvious degeneration, necrosis, a large number of collagen fibers of the cable hyperplasia, part visible pseudolobule formation. A. chinesis large, medium, low-dose group and colchicine group liver cell degeneration and necrosis reduced A. chinesis small, medium, and high-dose group was gradually reduced trend and A. chinesis large, middle dose group degree of reduction is particularly significant. Compared with model group, A. chinesis of large, medium and small dose group and colchicine group VEGF mRNA expression, A. chinesis of large, medium-dose group TGF-β1 mRNA expression reduce (P < 0.05); compared with colchicine group, A. chinesis of large, middle dose group of VEGF mRNA expression decreased (P < 0.05); A. chinesis of large, middle dose group of TGF-β1 mRNA expression decreased (P < 0.01), and compared with colchicine group, large dose group of of TGF-β1 mRNA expression decreased (P < 0.05). Compared with model group, A. chinesis of large, medium and small dose group and colchicine group Bcl-2 protein expression reduce (all is P < 0.05). But A. chinesis of large, medium and small dose group and colchicine group of Bax protein expression were increased (P < 0.05). A. chinesis regulation of VEGF, TGF-β1 may prevent the activation of hepatic stellate cells, liver tissue by up regulating the anti-apoptotic protein Bax and down pro-apoptotic protein Bcl-2 expression, thereby to improve the degree of liver fibrosis.
