Objective To study the value of tubal catheterization and hydrotubation using hysteroscopy in the assessment of tubal patency after laparoscopic operations for ectopic pregnancy.Methods Hysteroscopic tubal catheterization and hydrotubation was carried out for evaluating tubal patency in 56 cases of ectopic pregnancy at 2~24 months after laparoscopic salpingectomy or salpingotomy. Results Of 15 cases of salpingectomy,unilateral complete tubal unobstructedness was achieved in 9 cases(60.0%).Of 41 cases of linear salpingotomy,bilateral tubal unobstructedness was found in 18 cases(43.9%) and unilateral in 18 cases(43.9%).A follow-up observation for 4~25 months(mean,10.8 months) in 37 women with childbearing demand showed normal intrauterine pregnancy in 20 cases(54.0%),intrauterine pregnancy after in vitro fertilization(IVF) in 3 cases,and recurrent ectopic pregnancy in 1 case(2.3%).Conclusions Hysteroscopic tubal catheterization and hydrotubation is a direct and accurate procedure for evaluating tubal patency after laparoscopic operations for ectopic pregnancy.It may be taken as a guide in evaluating the possibility of normal intrauterine pregnancy.

Objective To investigate the role of peripheral CD14+monocyte-macrophages in the recognition of phosphorylated antigen by γδ T cells and its relationship with treatment outcome. Methods Three kinds of γδ TCR tetramers were used to stain PBMC collected from patients with tuberculosis ( TB) and neonatal umbilical cord blood samples. The proportions of various TB-specific antigen presenting cells (APC) in peripheral blood were analyzed, and their relationships with treatment outcome were assessed based upon clinical data. Results CD14+monocyte-macrophages both in tuberculosis patients′ peripheral blood and neonatal umbilical cord blood were the strongest binding cells to CD277 antibody and γδ TCR tet-ramers. The median (P50) of CD14+monocyte-macrophages reached the highest peak after taking anti-tu-berculosis treatment for about one month and patients′condition was improved obviously during this period. Conclusion This study elucidated that CD14+monocyte-macrophages accounted for the largest proportion of APC when γδ T cells recognized phosphorylated antigens, which provided reference data for further study on the mechanism of γδ T cells restrictively recognizing phosphorylated antigen and their significance in innate and adaptive immunity.
