Objective To investigate the expression of Uroplakin Ⅱ (UPⅡ) gene together with other conventional parameters in the patients with transitional cell carcinoma(TCC). Methods Total RNAs extracted from solid tumor tissues and blood samples of patients with TCC were reverse transcribed and subjected to polymerase chain reaction amplification (RT PCR).The products of RT PCR were analyzed by agarose gel electrophoresis. The expressions in solid tissues of other kinds of tumors and blood samples of non neoplasm patients served as controls. Results UPⅡ gene were expressed in all the solid tumor tissues of TCC(100%) and in the blood samples of 5 patients of T 3～T 4 neogrowth(39%), 2 of the 5 cases had hematogenous metastasis which became nondetectable after chemotherapy; UPⅡ gene has not been detected in the blood samples of T 1～T 2 TCC patients, the non neoplasm patients and other kinds of solid tumor tissues. Conclusions UPⅡ is one of the specific markers of urothelium.It can be found in TCC patients of stage T 3～T 4 and in patients with metastasis. The detection of UPⅡ in the blood sample might serve as a marker for chemotherapeutic efficacy.

Objective:To understand the output of research and education of clinical key Specialties in Henan Province, to analyze the current situation and existing problems, and to provide scientific evidence and suggestions for the improvement of specialist ability.Methods:Through the questionnaire survey to collect the scientific research data of key specialties from 2015 to 2019, apply Epidata 3.0 to input the data, use SPSS 21.0 software to carry out test and Mann Whitney U test, and carry out a comparative analysis of the national and provincial clinical key specialty discipline leaders, medical talent team, academic, scientific research and education output in Henan Province. Results:Academic literacy and scientific research ability of leaders of national and provincial key clinical specialties in Henan Province are equal. However, there is still a big gap in scientific research and education ability between national and provincial key clinical specialties in Henan Province.Conclusions:The provincial key clinical specialties need to improve the ability of scientific research and education in a more holistic way, further strengthen the medical talents team, and focus on the exchange of high-level academic platform and the cultivation of research talents.
