Arsenic could be detected in the main organs and tissues of rats after administration of a single dose. The arsenic was most accumulated in the spleen, hair, lung and suprarenal gland organs, and kidney, heart, liver, bladder and skin came next.

After 15 continuous days of administration, arsenic contents in kidney and bladder tissues increased appreciably besides suprarenal gland, lung, hair and spleen.

Adverse events were similar in both groups, and the incidence of symptomatic heart failure was lower than expected among those in the trastuzumab group (less than 2%), which supports "the accumulating evidence that trastuzumab can be given concurrently with anthracyclines with a low frequency of symptomatic cardiac dysfunction, provided that low cumulative doses or less cardiotoxic anthracyclines are used, and careful cardiac monitoring is done," the authors said.

作者表示，两组的不良事件发生率相似，曲妥珠单抗组症状性心力衰竭发生率低于预期(低于2%)，这支持如下观点，&越来越多的证据表明，如果应用的累积剂量较低或心毒性蒽环类药物较少且实施严密心脏监测，那么曲妥珠单抗与蒽环类药物就能够联用且所致的症状性心功能不全发生率较低。&

Results In univariate analysis, atrial fibrillation, huge left atrium, long course of left-sided valve diease, degradation of left heart function （LVEF 〈0.50）, tricuspid rheumatic pathological change, enlarged right atrium and single mitral valvar disease were significant risk factors of TR devdopment.

结果单因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长、左心功能低下（LVEF〈0.50）、右房增大（≥50mm）、三尖瓣风湿性病变及单纯二尖瓣病变是继发性TR进行性加重的危险因素；多因素分析显示心房纤颤、巨大左房、左心瓣膜病病程长及三尖瓣风湿性病变是继发性TR进行性加重的危险因素；远期随访显示，B组心功能改善明显优于A组，TR程度明显低于A组，C组术后无1例发生TR。
