Objective To evaluate the accuracy of the new and old electrocardiographic algorithms for differentiating the origins of outflow tract ventricular arrhythmias. Methods The clinical data of 202 patients treated between 2010 and 2013 were retrospectively reviewed for the investigations of the four algorithms including the transitional zone index, the V2 transition ratio, V2 R-wave duration and R/S-wave amplitude indices and the Sv2/Rv3 index. Results Regardless of rotation, the V2 transition ratio had the highest sensitivity (93.5%), while the Sv2/Rv3 index had the highest specificity (93.8). The maximal area under the ROC curve of four was more than 0.8, while the transitional zone index had the minimal area (0.804) with statistical significance (P < 0.001). In the patients with precordial transition, the V2 transition ratio had the highest sensitivity (93.9%), while the Sv2/Rv3 index had the highest specificity (94.7%). The maximal area under the ROC curve of four was more than 0.8 with no statistical significance (P>0.05). Conclusion Regardless of rotation, the Sv2/Rv3 index has the highest specificity and equal diagnostic value, with equal diagnostic value of the V2 transition ratio and V2 R-wave duration and R/S-wave amplitude indices. Compared with other algorithms, the Sv2/Rv3 index is simple and can be a complement as well for the direction of ablation therapy.

Objective To investigate the proper inner control genes suitable for mRNA expression level comparison of aging rat tissues.Methods Real-time reverse transcription PCR was used to examine in aging rat tissues the expression level of G3pd(glyceraldehyde-3-phosphate dehydrogenase),ACTB(?-actin),H3f3b(H3 histone,family 3B),Arbp(acidic ribosomal phosphoprotein P0)and 18S(18S ribosomal RNA).Results The most stably expressed housekeeping gene in aging rat kidney was ACTB,in heart and lung G3pd showed the minimum variation;Arbp expression was the most stable one in different tissues.Conclusion For aging rat intra-tissue mRNA normalization at least two housekeeping genes should be used: one is the ribosomal RNA gene 18S and another one is Arbp.

Objective:To investigate the effect and mechanism of lysine acetyltransferase 5(KAT5) on the radio-sensitivity of anaplastic thyroid carcinoma (ATC).Methods:The expression levels of endogenous KAT5 in ATC and normal thyroid cells were detected by Western blot and qRT-PCR. The effect of KAT5 specific inhibitor NU9056 on the radio-sensitivity of human ATC cells and normal thyroid cells was evaluated by colony formation assay. TCGA database, JASPAR database, along with Western blot, microRNA sequencing, qRT-PCR and dual-luciferase reporter assay were conducted to unravel the underlying mechanism.Results:The expression of endogenous KAT5 at the protein and mRNA levels in human ATC cells was significantly higher than that in normal thyroid cells. NU9056 could significantly enhance the radiosensitivity of human ATC cells to 8505C and CAL-62, whereas showed no sensitization effect on normal thyroid cell Nthy-ori 3-1. Knockdown of KAT5 and NU9056 both down-regulated the expression level of miR-210 in the TC cells, while NU9056 decreased the expression level of transcription factor c-Myc. The putative binding sites of c-Myc in the miR-210 promoter region were predicted, and transfection of c-Myc plasmid significantly enhanced the luciferase activity of miR-210 promoter. Elevated miR-210 level was associated with worse survival of patients with thyroid carcinoma. Down-regulated expression of miR-210 decreased the TET2 mRNA level, while inhibition of miR-210 increased the TET2 mRNA level.Conclusion:The aberrantly-activated KAT5/miR-210/TET2 pathway probably causes the radioresistance of ATC, becoming a novel sensitizing target for ATC radiotherapy in clinical practice.

ObjectiveTo compare detection rate of pulmonary nodules and the radiation doses of digital tomosynthesis (DTS) and MSCT chest scanning by using the anthropomorphic chest phantom which containsthermoluminescent dosimeters( TLD ) and simulated pulmonary nodules.Methods The radiation doses of DTS and MSCT scanning were measured by using the anthropomorphic chest phantom which contains 45 TLD and simulated pulmonary nodules.The radiation doses of najor organs were converted into effective dose ( ED ). Three radiologists of different clinical experiences independently reviewed and recorded the density,diameter and position of pulmonary nodules.The sensitivity of nodule detection by DTS and MSCT were compared by Fisher exact test and Chi-square test. The paired t test was conducted to analyze the dose levels of DTS and MSCT.ResultsThe sensitivity of detection nodule by DTS and MSCT were 66.7％ (30/45) and 91.1％ (41/45) respectively.Statistically significant difference between the two examinations existed ( x2 =8.073,P ＜ 0.05).The sensitivity of detection - 650 HU ground glass opacity pulmonary nodule by MSCT and DTS were 93.3％ (14/15) and 73.3％ (11/15) respectively.There was no significant difference between DTS and MSCT ( P ＞ 0.05 ).The sensitivity of detection - 800 HU ground glass opacity nodule and ground glass opacity nodule (d ＜ 8 mm) by DTS were 33.3％ (5/15) and 16.7％ (2/12) respectively,which were lower than those by CT[80.0％ (12/15) and 66.7％ (8/12)].The radiation doses of DTS for various organs in the chest were lower than those of CT. Statistical significant difference between DTS and MSCT existed ( lung t =19.69,thoracic vertebral t =30.01,heart t =16.33,liver t =5.06,breast t =9.43,thyroid gland t =8.05 ;P ＜ 0.05).The effective doses of the DTS and MSCT were 0.65 and 7.71 mSv respectively.ConclusionsThere is no difference between the DTS and MSCT in the detection rate of -650 HU ground glass opacity nodule.For detecting the ground glass opacity nodule ( - 800 HU) and ground glass opacity nodule (d ＜ 8 mm),MSCT is superior to DTS. However,the radiation dosage of DTS is 8.41％ of the MSCT scanning.
