【摘要】 目的 比較酸性成纖維細胞生長因子(acid fibroblast growth factor,aFGF或FGF1)在正常乳腺組織、乳腺良性腫瘤及乳腺癌中的表達差異,探討FGF1與乳腺癌血管生成的關系。方法 應用免疫組織化學(immunohistochemistry,IHC)SP法檢測FGF1在40例乳腺癌組織、12例良性乳腺腫瘤組織及12例正常乳腺組織中的表達情況；以CD34抗體標記血管內皮細胞CD34抗原行乳腺癌組織微血管密度(micro vessel density,MVD)計數。〖HTH〗結果〖HTSS〗 FGF1在40例乳腺癌中的陽性表達率（57.5%，23/40)顯著高于12例乳腺良性腫瘤組織中陽性表達率(16.7%,2/12)以及正常乳腺組織陽性表達率(0,0/12),差異有統計學意義(Plt;0.05)；良性腫瘤組FGF1表達率和正常乳腺組織比較無統計學意義(Pgt;0.05)。40例乳腺癌組織MVD計數為(70.17±29.33)個/HP,在23例FGF1陽性組中MVD計數為(89.48±23.23)個/HP,顯著高于17例陰性組(44.06±12.53)個/HP,差異有統計學意義(Plt;0.05)。〖HTH〗結論 〖HTSS〗FGF1可能參與乳腺癌微血管生成。
Objective To explore and implement a systematic, case guided online interactive training course for neurologists to improve their diagnosis and treatment of rare genetic diseases. Methods Doctors who participated in the course investigation of the neurogenetic project of the Department of Neurology of Peking Union Medical College Hospital between January and September 2021 were selected. Based on andragogy theory, a genetics training course for neurologists was developed by applying Kern’s six steps of curriculum development. According to the time of participating in the doctor’s courses, they were divided into three groups: completed all courses (10.7 h group), completed more than 1/2 courses (5.3～10.7 h group) and completed less than 1/2 courses (<5.3 h). According to the length of service, they were divided into groups of less than 10 years, 10-20 years and more than 20 years. Analyze the benefit difference of different doctors’ training time, and collect their feedback scales on the curriculum for the improvement of follow-up courses. Results A total of 54 doctors were included. Among them, 17 (31.5%) completed all courses, 29 (53.7%) completed more than 1/2 courses, and 8 (14.8%) completed less than 1/2 courses. There was a statistically significant difference among the three groups in the self-assessment improvement score (H=12.341, P=0.002). The results of pairwise comparison between groups of self-assessment improvement score showed that the <5.3 h group was lower than that of the 10.7 h group (P=0.007), and the the <5.3 h group was also lower than that of the 5.3～10.7 h group (P=0.002). 33 (61.1%) in the less than 10 years group, 16 (29.6%) in the 10-20 years group, and 5 (9.3%) in the more than 20 years group. There was no correlation between participating in work and course time (rs=0.113, P=0.418). 54 (100.0%) believed that they had more than moderate help (≥3 points). Most doctors (>90%) had a good evaluation of the curriculum. Conclusion The periodic neurogenetic re-education project is helpful for clinical diagnosis and treatment of rare neurogenetic diseases.
