Objective:To explore the influencing factors of residual thyroid clearance with 131I after surgery in patients with differentiated thyroid cancer (DTC). Methods:A retrospective analysis was conducted on the clinical data of 100 DTC patients admitted to the Hunan Provincial People′s Hospital from January 2018 to February 2021 who underwent 131I treatment for the first time. The success rates of first thyroidectomy using different doses of 131I, different pathological types, and different treatment times were compared, and logistic regression analysis was conducted to investigate the influencing factors of the efficacy of first postoperative 131I thyroidectomy in DTC patients. Results:A total of 54 patients successfully cleared residual thyroid, 46 patients failed to clear residual thyroid, and the success rate of clearing residual thyroid was 54%. The success rates of first clearance of residual thyroid in patients with 131I doses of 80 mCi, 90 mCi, and 100 mCi were 37.50%(12/32), 52.78%(19/36), and 71.88%(23/32), respectively, with statistically significant differences among the groups ( P<0.05); The success rates of first removal of residual thyroid in patients with follicular carcinoma, mixed papillary follicular carcinoma, and papillary carcinoma were 65.71%(23/35), 39.13%(9/23), and 52.38%(22/42), respectively. There was no statistically significant difference between the groups ( P>0.05); The success rates of first removal of residual thyroid in the group1 of patients (treatment time<3 months), the group2 of patients (treatment time 3-12 months), and the group3 of patients (treatment time>12 months) were 68.09%(32/47), 44.44%(16/36), and 35.30%(6/17), respectively. There was no statistically significant difference between the groups ( P>0.05); There was no statistically significant difference in the success rate of clearing residual thyroid in DTC patients of different genders, ages, pathological stages, and thyroid stimulating hormone (TSH) levels (all P>0.05); The difference in the success rate of clearing residual thyroid in DTC patients with different metastatic conditions and stimulating thyroid globulin (sTg) was statistically significant (all P<0.05); sTg, postoperative lymph node metastasis, and postoperative distant metastasis were independent risk factors for the efficacy of residual thyroid clearance in DTC patients for the first time after surgery (all P<0.05). Conclusions:The influencing factors for the efficacy of the first 131I in removing residual thyroid include differences in 131I dosage, presence or absence of metastatic lesions during treatment, Tg levels, etc. Reducing Tg levels is an important factor in improving remission rate, and controlling lymph nodes and distant metastasis is a key factor for the successful efficacy of the first 131I in removing residual thyroid.

Objective To explore the significance of serum β-nerve growth factor(β-NGF)and tumor necrosis factor-related apoptosis-inducing ligand(TRAIL)testing in clinical diagnosis and prognosis assessment in patients with pulmonary heart disease(PHD)complicated with pulmonary artery hypertension(PAH).Methods A 1:1 case-control study was conducted in Daxing District People's Hospital of Beijing from January 2019 to June 2022,in which 86 patients with PHD complicated with PAH and 86 patients with isolated PHD were selected as case group and control group.Retrospective analysis was conducted.The case group was divided into mild PAH group(n=39),moderate PAH group(n=25)and severe PAH group(n=22)according to pulmonary artery systolic pressure(PASP).Meanwhile,the case group was divided into good prognosis group(n=75)and poor prognosis group(n=11)based on the outcomes after one year of discharge.Demographic data and laboratory examination indicators of study subjects were collected,and serum β-NGF and TRAIL levels were measured using enzyme-linked immunosorbent assay(ELISA).Pearson product-moment correlation analysis was used to assess the relationship among β-NGF,TRAIL and PASP.Logistic regression analysis was performed to identify factors influencing PAH in patients with PHD.ROC curve was used to evaluate the diagnostic value of β-NGF and TRAIL for PAH.Cox proportional hazards regression analysis was carried out to assess the relationship among β-NGF,TRAIL and poor prognosis in patients with PHD complicated with PAH,and ROC curve was used to evaluate its predictive value for poor prognosis.Result Compared with control group,the duration of PHD in case group was longer(8.63±1.27 years vs 5.49±1.15 years),and serum β-NGF level(26.97±8.25 ng/ml vs 22.14±7.32 ng/ml)and TRAIL level(2.83±0.76 ng/ml vs 1.71±0.68 ng/ml)were increased,with significant differences(t=17.006,4.064,10.183,all P＜0.05).Serum β-NGF and TRAIL had certain diagnostic values for PAH in PHD patients,with AUC of 0.842 and 0.838,respectively.And the combined diagnostic AUC was 0.920,which was higher than that of single indicators(Z=3.416,3.508,all P＜0.05).Serum β-NGF(23.26±5.13 ng/ml,27.83±5.57 ng/ml,32.57±6.02 ng/ml)and TRAIL(2.24±0.65 ng/ml,2.89±0.71 ng/ml,3.81±0.90 ng/ml)levels among patients with mild PAH,moderate PAH,severe PAH were sequentially elevated,and the differences were significant(F=20.624,31.972,all P＜0.05).Serum β-NGF and TRAIL were positively associated with PASP(r=0.673,0.659,P＜0.05).Serum β-NGF(36.34±8.05 ng/ml)and TRAIL(3.49±1.01 ng/ml)levels in poor prognosis group were higher compared to good prognosis group(25.59±7.28 ng/ml,2.73±0.89 ng/ml),and the differences were significant(t=4.516,2.604,all P＜0.05).Logistic regression analysis showed that,the PHD duration[OR(95％CI):1.784(1.135～2.806)],β-NGF[OR(95％CI):1.976(1.108～3.523)]and TRAIL[OR(95％CI):1.866(1.123～3.101)]were independent risk factors for occurrence of PAH in patients with PHD(all P＜0.05).Multivariate COX proportional risk regression results showed that PHD duration[OR(95％CI):1.167(1.082～1.364)],β-NGF[OR(95％CI):1.322(1.134～1.649)],TRA-IL[OR(95％CI):1.259(1.087～1.590)]were independent risk factors for poor prognosis in patients with PHD complicated with PAH(all P＜0.05).Serum β-NGF and TRAIL could predict the poor prognosis in patients with PHD complicated with PAH,with AUC of 0.863 and 0.881,respectively.The combined diagnostic AUC was 0.907,which was higher than that of single indicators(Z=2.905,3.128,all P＜0.05).Conclusion Elevated serum β-NGF and TRAIL were independent risk factors for PAH and were associated with severity of PAH.Early combined detection of β-NGF and TRAIL can improve the diagnostic value for PAH and predict poor prognosis of patients.

Early recognition and treatment for early warning electrocardiogram (ECG) of sudden death are very important to prevent and treat malignant arrhythmia and sudden death. Previous studies have found that R-on-T and T wave alternation, and QT interval prolongation are closely related to malignant arrhythmia or sudden death, which are included in the critical value of ECG.By analyzing the ECG characteristics of 4 patients with sudden death, we found that although the causes of the patients were different, there were transient prolongation of QT interval after premature contraction in 12 lead ECG, followed by malignant arrhythmia or sudden death. Thus, we thought that the transient prolongation of QT interval after premature contraction had a high value for warning malignant arrhythmia or sudden death. This phenomenon should be paid enough attention to reduce the risk of sudden death.
