Stent entrapment is a rare complication of percutaneous coronary intervention.In recent years,with the development of distal radial artery puncture technology,the rare complications related to distal radial artery have been gradually understood.This article describes a patient who underwent coronary intervention through a distal radial approach,and the stent was dislodged and trapped in the far radial artery.The patient came to our hospital for stent implantation because of acute extensive anterolateral myocardial infarction.During the intervention,the balloon could not be filled when the stent was released from the left anterior descending artery,and the retracting stent could not be used to remove the guide catheter.The stent was dislodged and embedded in the distal vessel.The sheath was inserted through the proximal radial reverse puncture,and the stent was captured with a snare and removed.

Metabolic reprogramming is a hallmark of cancer, including lung cancer. However, the exact underlying mechanism and therapeutic potential are largely unknown. Here we report that protein arginine methyltransferase 6 (PRMT6) is highly expressed in lung cancer and is required for cell metabolism, tumorigenicity, and cisplatin response of lung cancer. PRMT6 regulated the oxidative pentose phosphate pathway (PPP) flux and glycolysis pathway in human lung cancer by increasing the activity of 6-phospho-gluconate dehydrogenase (6PGD) and α-enolase (ENO1). Furthermore, PRMT6 methylated R324 of 6PGD to enhancing its activity; while methylation at R9 and R372 of ENO1 promotes formation of active ENO1 dimers and 2-phosphoglycerate (2-PG) binding to ENO1, respectively. Lastly, targeting PRMT6 blocked the oxidative PPP flux, glycolysis pathway, and tumor growth, as well as enhanced the anti-tumor effects of cisplatin in lung cancer. Together, this study demonstrates that PRMT6 acts as a post-translational modification (PTM) regulator of glucose metabolism, which leads to the pathogenesis of lung cancer. It was proven that the PRMT6-6PGD/ENO1 regulatory axis is an important determinant of carcinogenesis and may become a promising cancer therapeutic strategy.

Objective To analyze the safety of atrial septal defect closure using Da Vinci surgical system. Methods Totally 23 atrial septal defect patients hospitalized from July to December 2016 underwent atrioseptopexy by using Da Vinci surgical system. The effect of atrioseptopexy was observed under cardiopulmonary bypass conditions. Results All the patients had the operation completed successfully, with the operating time being (2.8 ±0.5)h, the intraoperative cardiopulmonary bypass time being (35.4±18.4)min, aortic clamping time being (25.9±8.4)min, postoperative mechanical ventilation time being (5.7±1.5)h, amount of thoracic drainage fluid from 50 to 300 ml and postoperative hospital stay being (7 ±5.1)d. The follow-up 1 and 3 months after discharge showed there were no complications and death occurred, and the examinations by chest X-ray film and heart color ultrasound found no abnormality. Conclusion Da Vinci surgical system gains advantages in safety, reliability, patient satisfaction, operative incision and surgical trauma, and thus is worthy promoting clinically.

BACKGROUNDThe importance of diagnosis of thyroid dysfunction during pregnancy has been widely recognized. Our study was designed to compare two different detection reagents between Abbott and Roche and to establish the gestational related reference intervals for thyroid function tests (TFT) in Chinese women and to assay the reference ranges with the American Thyroid Association recommended standard.

METHODSSerum samples were collected from 693 normal pregnant Chinese women and divided into five groups according to their gestational age: 9-13, 16-20, 24-28, 32-34 and 37-40 weeks. Thyroid stimulating hormone (TSH) and free thyroxine (FT4) levels were determined by two different detection reagents: Abbott Architect I 2000 and Roche Cobas Elecsys 600. The reference ranges of the TFT indexes were calculated according to the National Academy of Clinical Biochemistry (NACB). The 2.5th and 97.5th percentiles of each stage were calculated, and the results were analyzed by one-way analysis of variances, t-test, and Spearman correlation analysis.

RESULTSThyroid hormone levels varied greatly among different gestational stages. TSH levels, as assessed via two different TSH ELISA kits showed consistent changing pattern during pregnancy and displayed linear correlation (P < 0.001). In 9-13 gestational weeks, TSH levels were significantly lower than that of other groups; and in 37-40 gestational weeks, it was higher than that of other groups (all P < 0.001). TSH reference ranges determined by Roche detection reagent in each group were higher than those by Abbott detection reagent (P < 0.01 respectively). FT4 levels were higher in 9-13 gestational weeks than that of other groups (P < 0.001). FT4 levels determined by Roche reagent were higher than Abbott reagent in 9-13 weeks, (P < 0.001), and lower in 24-28 and 37-40 weeks (P < 0.001 and P = 0.016, respectively). The TSH level was correlated with FT4 levels in 9-13 gestational weeks by detection reagents (for Abbott reagent, r=-0.319 for FT4 P < 0.001; for Roche reagent, r=-0.352 for FT4, P <0.001).

CONCLUSIONAccurate evaluation of TFT in pregnant women should be based on the gestational-related reference intervals in Chinese population, and different detection reagents should also establish their own reference intervals.
