Background and purpose:Thyroglobulin antibody (TgAb) is often positive in papillary thyroid carcinoma (PTC) patients. This study aimed to investigate the effect of TgAb on radioiodine ablation efficacy in PTC patients.Methods:A total number of 329 PTC patients with no distant metastasis were included and classified into 2 groups[G1 group (>115 U/mL,n=84) and G2 group (<115 U/mL,n=245)], G2 group was further divided into 2 subgroups[S1 (>40 U/mL,n=31) and S2 (<40 U/mL,n=214)], before131I ablation. The median follow-up time was 24 months after a total or subtotal thyroidectomy and subsequent131I ablation. The efficacy in terms of131I ablation success rates (IBR) between two groups were compared and the influencing factors were analyzed according to criteria posed by 2015 American Thyroid Association Guidelines, then the effect of131I dose on IBR was also explored.Results:Female and younger age were more prevalent in patients with high TgAb (P<0.05). The G1 group presented lower IBR over the G2 group (35.7%vs 72.7%,P=0.000). Moreover, S1 group also presented lower IBR over S2 group (54.8%vs 75.2%,P=0.017), indicating the adverse effect from high titer TgAb on IBR. No matter high or low dose, the G1 group presented lower IBR (34.1%vs 71.9%, 37.2%vs 73.2%;P=0.000). However, IBR did not differ in G1 or G2 group either with high or low dose131I (P>0.05). TgAb was the only adverse indicator correlating with IBR in multi-logistic regression analysis (P=0.018).Conclusion:TgAb could negatively affect131I ablation efficacy, while increasing the dose of131I failed to improve the success rate in such cases.

Objective To identify the role of resistin in insulin resistance(IR) by endoplasmic reticulum(ER) stress in human umbilical vein endothelial cells ( HUVECs) and in rats.Methods HUVECs were cultured in vitro and disposed by resistin (R) or tauro ursodesoxycholic acid (tudca).Expressions of GRP78, P-akt and P-eNOS were determined using Western blotting.Thoracic aortic rings were made and their dilation function exposed to different concentrations of insulin was detected.Changes of vascular morphology were observed by HE staining.Results Results of Western blotting showed that expression of GRP78 was remarkably increased,but P-akt and P-eNOS were markedly decreased in R group.However, there was no difference in expressions of GRP78, P-akt and P-eNOS between tudca group and control group.The insulin induced vasodilation was decreased in R group and there was no difference between tudca group and control.Using HE staining, the R group showed significant medial thickening and proliferation of smooth muscle.Conclusion Resistin can induce insulin resistance in vascular endothelium cells by ER stress.

Objective This present study explores and evaluates the effect of preliminary implementation in the clinical therapy programs for patients with chronic Keshan disease (CKD) in the disease seriously-affected endemic areas.Methods In 2010,seventy-six CKD patients with heart failure were chosen from Huangling and Xunyi Counties in Shaanxi Province,where incidences of CKD were high.Besides taking sodium selenite,all patients were given treatment with fixed prescription,which included angiotensin-converting enzyme inhibitor (captopril),β-blocker (propranolol),diuretics (hydrochlorothiazide,spironolactone) and cardiac (digoxin) for 4 months.The changes before and after treatment were analyzed,which included the changes of heart function by the United States of America New York Heart Association(NYHA) fractionation,cardiothoracic ratio,electrocardiogram,left ventricular ejection fraction(EF) and fractional shortening(FS).The therapeutic effect was subsequently evaluated.Results Seventy-four cases of the seventy-six CKD patients completed the treatment observation.The improvement rate of heart function was 81.1％ (60/74) after treatment.The elimination rates of ectopic rhythm,conduction block and ST-T changes were 37.5％ (9/24),2.7％ (1/36) and 26.9％ (7/26),respectively.The cardiothoracic ratios of heart function NYHA Ⅱ,Ⅲ and Ⅳ were 0.504 ± 0.051,0.572 ± 0.054 and 0.632 ± 0.063 before treatment.After treatment,the cardiothoracic ratios were 0.486 ± 0.048,0.538 ± 0.046 and 0.607 ± 0.048,which were reduced in all groups (t =2.643,6.641,3.005,all P ＜ 0.05),while the D-value of cardiothoracic ratio changes before and after treatment was not significantly different(F =3.005,P ＞ 0.05).Both the mild reduction group(35％≤EF ＜ 50％) and the moderate-severe group(EF ＜ 35％) EF were (43.62 ± 4.58)％,(27.57 ± 3.69)％ before treatment and were (48.21 ± 10.01)％,(36.57 ± 6.60)％ after treatment,EF were increased in the two groups,while the changes before and after treatment were significantly different(t =-2.911,-3.334,all P＜ 0.05).The EF D-value of the two groups was (4.59 ± 8.48)％ before treatment and was (9.00 ± 7.14)％ after treatment,which were not significantly different(P ＞ 0.05).FS was higher compared with pre-treatment in FS reduction group(FS ＜ 25％) and the changes before and after treatment[(19.75 ± 2.88)％,(21.92 ± 5.67)％] were significantly different(t =-2.297,P ＜ 0.05).Conclusions This study shows that the feasibility of clinical treatment of patients with CKD is very promising.The treatment of fixed prescription is effective.
