云南玛咖产业发展现状及促进对策分析（英文）

药食植物玛咖是重要的保健品原料,近年来云南省玛咖产业发展迅速,但由于起步较晚、基础薄弱,种植、加工与国外相比仍有较大的差距。从玛咖生产基地、加工企业、优势区域布局、种植与初加工技术体系、经济效益等方面阐述了云南省玛咖产业发展现状,并对制约其产业发展的主要因素进行分析,最后提出了加强组织领导,抓好宏观调控;加大财政投入,拓宽投融资渠道;加快原料生产加工基地建设;加强现代科技研发工作,建立科技支撑体系;加快培育龙头企业;构建市场营销体系;促进集聚发展,严格质量标准等促进对策。     

Bilateral Testicular Mixed Germ Cell-sex Cord-stromal Tumours in a Stallion

An 18-year-old Friesian stallion was examined approximately one week after reportedly presenting scrotal swelling due to torsion of the spermatic cords. Upon presentation no scrotal swelling was noted, the testes were normally oriented, and no abnormalities of the spermatic cords were noted. However, both testes were smaller than expected for a mature stallion and deep palpation revealed that the consistency of the testes was nodular. Ultrasonographic evaluation of the testes revealed diffuse heterogeneous parenchyma with multiple hypoechoic nodular areas. Grossly, the testicular parenchyma was effaced by multiple gray-tan nodules of varying consistency interspersed with gray-white bands of tissue. Microscopic analysis revealed multiple pleomorphic neoplastic foci disseminated throughout both testes. Histological and immunohistochemical features were atypical and consistent with the diagnosis of bilateral testicular mixed germ cell-sex cord stromal tumours. Bilateral testicular tumours and testicular mixed cell tumours are extremely rare in stallions and this is the first report of bilateral testicular mixed germ cell-sex cord-stromal tumours in a stallion. Our findings indicate that certain ultrasonographic characteristics are suggestive of testicular tumour and that immunohistochemistry markers can be used to better characterize testicular neoplasms in stallions.
