However, until recently more and more studies show the convincing evidence that it most probably originates from tubal cells. It has a close relationship with the development of serous tumors, especially low-grade serous carcinoma. The lesion does cause symptoms and signs, such as chronic abdominal pain or tumor-like mass, though it is often found accidently for other gynecologic problems. Occasionally atypical endosalpingiosis needs to be differentiated from a malignancy when it appears in an unusual site with worrying morphologic presentations or under some special circumstances. Owing to the facts that it may evolve quietly and continuously towards serous tumors, and that the lesions at different sites may evolve independently, the outcomes of its evolution can eventually kill the patient. Therefore, a proper recognition of the lesion will translate it into an adequate care for those patients. This review summarizes the most recent findings and makes thoughtful comments.展开更多

文摘目的探讨化瘀消癥杀胚中药复方(丹参、赤芍、桃仁、紫草和天花粉)对人输卵管妊娠滋养细胞增殖、凋亡的影响。方法采用CCK8法检测经中药复方水煎剂处理人输卵管妊娠滋养细胞的增殖情况,采用Hoechst染色法和流式细胞术检测48 h后细胞凋亡情况,设未经复方中药处理的细胞为空白对照组。结果与空白对照组相比,各剂量中药复方对人输卵管妊娠滋养细胞增殖均有明显的抑制作用,呈剂量和时间依赖性。48 h IC50为27.86 mg/mL;中药复方高、中、低剂量组中人输卵管妊娠滋养细胞呈现典型的凋亡形态学改变,其凋亡率分别为(24.57±1.08)%、(18.30±1.18)%和(14.37±2.64)%,与空白对照组(9.57±0.76)%相比明显增加(F=47.88,Ρ=0.00)。结论化瘀消癥杀胚中药复方可能通过抑制人输卵管妊娠滋养细胞增殖,促进细胞凋亡从而达到中止输卵管妊娠的目的。
