Objective To evaluate the impact of low-dose 131I therapy and high-dose 131I therapy on the clinical outcome in PTC patients coexisting with Hashimoto's thyroiditis (HT).Methods A total of 140 non-distant metastatic PTC patients (16 males,124 females,age range:16-66 years) from July 2010 to December 2014 were enrolled in this retrospective study.Patients concurrent with HT (n=84,group A) were divided into low-dose group (1 110 MBq,n=56,group A1) and high-dose group (5 550 MBq,n=28,group A2) according to 131I ablation dose.Patients without HT (n =56) were enrolled as control group (group B),and received 1 110 MBq of 131I.The thyroid remnant ablation outcome was evaluated according to 131I diagnostic whole-body scan (Dx-WBS),neck ultrasonography (US),serum Tg and TgAb level 6-8 months after 131I ablation therapy.The successful ablation rates were compared by x2 test.Kruskal-Wallis rank sum test was also used.Results There were no significant differences among the 3 groups in terms of both clinicopathological features and postoperative remnant thyroid (H:0.203-2.944,x2:0.271-0.970,all P＞0.05).When negative Dx-WBS and US were deemed as successful ablation criterion,complete ablation rate was found significantly more in group B (94.6％,53/56) than that in group A1 (82.1％,46/56;x2=4.264,P＜0.05),but no significant difference was found between group A2 (85.7％,24/28) and group A1 (x2 =0.318,P＞0.05).When combining negative sTg (sTg＜1 μg/L,TgAb＜46 kU/L) with the above 2 criterions to assess remnant ablation outcome,group B also had a higher successful rate to achieve complete ablation (85.7％,48/56) compared with group A1 (75.6％,34/45),but without statistical significance (x2=2.978,P＞0.05),and no difference was observed between group A2 (12/15) and group A1 (x2=1.320,P＞ 0.05).Conclusion Non-distant metastatic PTC patients coexisting with HT has undesirable 131I ablation outcome compared with those without HT,increasing 131I dose is unhelpful to enhance efficiency of remnant ablation for PTC patients with HT.

Objective To investigate the clinical value and safety of cedilanid, esmolol in the treatment of atrial fibrillation. Methods From August 2014 to August 2016 our Hospital from 117 patients with atrial fibrillation clinical data, according to the random number distribution principle, the patients were divided into observation group 59 cases and control group of 58 cases, all patients were given the treatment of primary disease, the clinical symptoms, the patients in the observation group were given oxygen, has given furosemide, cedilanid, after micro injection pump intravenous nitroglycerin, 5-20 g/min. Start after the injection of nitroglycerin, establish another vein channel, every 30 min to 0.2 mg patients, the treatment group were treated with intravenous injection of small dose esmolol. The clinical efficacy, ventricular rate, systolic blood pressure, diastolic blood pressure and adverse reactions were observed in two groups. Results The early and late effective rates of the two groups were not significantly different. The observation showed that after treatment, the ventricular rate, systolic pressure and diastolic pressure in the observation group were significantly higher than those in the control group (P<0.05), and the incidence of adverse reactions in the two groups was significantly different (P<0.05). Conclusion High dose cedilanid combined with small dose esmolol in treatment of atrial fibrillation, obvious curative effect, high safety, can choose the appropriate application.

Objective To investigate the relationship between the initial change of Tg and clinical outcome in DTC patients with pulmonary metastases after 131I treatment.Methods A total of 47 DTC patients (13 males,34 females;average age (41.6±16.3) years) with pulmonary metastases from January 2008 to June 2014 were retrospectively analyzed.Patients were divided into 3 groups according to the variation of Tg: G1 with a declined (more than 50％) Tg;G2 with a declined (less than 50％) Tg or an increased (less than 10％) Tg;G3 with an increased (more than 10％) Tg.The median follow-up time was 1 501 d.Clinical outcomes were divided into remission,stable disease and progressive disease according to the serum test and imaging results.Data analysis was performed by χ2 test and Fisher exact test.Results The percentage of G1,G2,G3 patients was 44.7％(21/47),40.4％(19/47),and 14.9％(7/47) respectively.Results of follow-up showed 19.0％(4/21) patients achieved remission and 81.0％(17/21) with stable disease in G1.There were 2/19 with remission,12/19 with stable disease and 5/19 with progression disease in G2.All patients (7/7) had progressive disease in G3.The clinical outcome was related to the variation of Tg after 131I treatment (Fisher exact test,P<0.01).Conclusions Initial Tg after 131I treatment could be a predictor to the outcome of patients.The increased Tg level indicates a high possibility of 131I refractory disease.

Methods According to some theory, automatic cancellation model was built up in computer with Matlab software. Results Simulation experiment shows that the cancellation composed signal So(t) is not correlative with the time and precision of auto-counteract but the amplitude and phase of clutter signal. Conclusion The results of the experiment have instructive significance about design of auto-counteract circuit.

Background and purpose:This study aimed to investigate the relationship between lymph node metastatic rate (LR) and response to radioiodine therapy in patients with papillary thyroid carcinoma (PTC).Methods:A total number of 143 PTC patients after radioiodine therapy were included and classified into 4 groups [Ⅰ(0%-10%),Ⅱ(>10%-25%),Ⅲ(>25%-50%),Ⅳ(>50%)] according to the lymph node metastatic rate, and the responses to initial radioiodine therapy after a median follow-up period of 20.7 months were evaluated. They were classiifed into 4 groups [excellent response (ER), indeterminate response (IDR), biochemical incomplete response (BIR), and struc-tural incomplete response (SIR)] according to the guideline proposed by 2015 American Thyroid Association. One-Way analysis of variance,χ2 test and Kruskal-Wallis test were used to evaluate the differences in basic clinicopathological features and clinical responses among the 4 groups. The ROC curve was analyzed to evaluate the clinical value of lymph node metastatic rate for predicting ER and optimal cut-off point.Results:There were no signiifcant differences in gender and T-stage among 4 groups (P>0.05). However,Ⅰ group was signiifcantly older than the other 3 groups (P=0.001). With the increase of lymph node metastatic rate, the number of ER cases decreased, while cases of BIR and SIR generally increased. Compared with the other 3 groups, less cases of ER (27.8%), while more BIR (27.8%) or SIR (11.1%) were observed in groupⅣ (H=18.816,P=0.000). Cut-off value of lymph node involved rate was 52.27%, with a better speciifcity of predicting ER. Area under the ROC curve was 0.668.Conclusion:The higher lymph node metastatic rate in patients with PTC, the worse clinical outcome it could be. A cut-off value of lymph node metastatic rate 52.27% is a speciifc independent predictor for the clinical outcome in PTC patients treated with radioiodine therapy.

Objective To investigate the molecular mechanism of protection of ischemia preconditioning on renal ischemia reperfusion injury. Methods Male C57/BL6N mice were randomly divided into two groups: in IR group, 35 min ischemia was induced by occlusion of both renal pedicles followed by 24 h perfusion (I/R). 15 min ischemia was induced 4 days before I/R in IPC group. Blood sample and kidney were collected in IR and IPC group after 24 h perfusion. Serum creatinine (Scr) and histological changes were used to evaluate the renal injury. PHD2 and HIF-1αwere evaluated by Western blotting, miR-21 expression was confirmed by real-time PCR. In vitro, hypoxic model was established by 1% O2 in HK-2 cells. Knockdown of miR-21 in hypoxic model was perfermed by locked nucleic acid modified-anti-miR-21 transfection. The levels of miR-21, HIF-1α and PHD2 mRNA were confirmed by real-time PCR. The levels of HIF-1α and PHD2 proteins were tested by Western blotting. Results In vivo, Compared with IR group, the renal function and histological changes were improved in IPC group (P<0.01). Compared with IR group, the expression of miR-21(P<0.01) and HIF-1α(P<0.05) were increased in IPC group, while PHD2 was reduced (P<0.01). In vitro, hypoxia reduced miR-21. The inhibition of miR-21 could increased the expression of PHD2 (P<0.05). Conclusions Ischemia preconditioning may exert protection against renal ischemia reperfusion injury by inhibiting PHD2.
