The present study revealed the alkaline and acid phosphatase distribution in the head sarcoma of goldfish. And the histochemical staining in situ by calcium-cobalt method and lead nitrate method displayed a large amount of alkaline and acid phosphatases in the head sarcoma, with higher enzyme activity. The alkaline and acid phosphatases belong to hydrolases, which are widely present in various tissues. The results showed that the activity of external sarcoma is similar to the middle one, while there was more alkaline phosphatase near to the tissue sarcoma under the goldfish scales. And they have the strong activity. The study will lay the theoretical basis on enhancing the ornamental value of goldfish.展开更多
We reviewed the case notes of 203 patients who were treated for sarcomas of the oral and maxillofacial region over a period of 5 years.

There were 98 male cases (mean age 31.4 ± 12.8 years) and 105 female cases (mean age 29.3 ± 10.4). Kaposi’s sarcoma accounted for 82.8% cases, and rhabdomyosarcoma 6.9% followed by osteosarcoma and chondrosarcoma at 2.5% each. Except for Kaposi’s sarcoma, surgery in combination with radiotherapy and/or chemothe- rapy was the main stay of treatment. Survival data was not available for most of our patients.展开更多

目的本研究旨在探索头颈部滑膜肉瘤(synovial cell sarcoma of the head and neck,SCSHN)患者的临床病理特征和生存预后。同时,通过开发列线图来预测SCSHN患者的总生存(overall survival,OS)和疾病特异性生存(diseasespecific survival,...目的本研究旨在探索头颈部滑膜肉瘤(synovial cell sarcoma of the head and neck,SCSHN)患者的临床病理特征和生存预后。同时,通过开发列线图来预测SCSHN患者的总生存(overall survival,OS)和疾病特异性生存(diseasespecific survival,DSS),从而为患者提供更准确的风险分层。方法回顾性收集了2004年至2019年期间来自监测、流行病学和最终结果(Surveillance Epidemiology and End Results,SEER)数据库中SCSHN患者的数据。利用Kaplan-Meier进行生存分析,同时利用单变量和多变量Cox分析确定其预后影响因素,并构建OS和DSS列线图。此外,使用C指数、时间相关的受试者操作特征曲线以及校准图验证了列线图的性能。结果共纳入了166例患者,平均年龄为36岁。5年OS率和DSS率分别为71.0%和74.8%。大多数患者接受了手术(84.9%)和放疗(68.1%)。单因素分析结果显示,年龄、肿瘤大小、SEER分期和是否接受放疗是OS和DSS的重要预后因素。在多因素Cox回归分析中,年龄≤50岁、肿瘤直径>5cm和SEER分期为远处病变的患者具有较差的OS和DSS。基于多因素筛选出的预后因素,本研究开发了相应的列线图,并通过C指数、受试者操作特征曲线和曲线下面积以及校准曲线评估和验证列线图的性能,而且与传统的SEER分期系统相比,该列线图预测SCSHN患者的OS和DSS有更高的准确性和更好的性能。此外,基于列线图开发新型风险分层系统,可观察到高风险亚组患者的OS和DSS显著差于中、低风险亚组(P<0.001)。结论本研究构建的列线图方面优于传统的SEER分期,可以对SCSHN患者的长期生存进行个体化预测,并根据风险有效地指导治疗。展开更多
