Objective To explore the procedure selection of laparoscopic surgery in the treatment of tubal pregnancy.Methods A total of 187 patients with tubal pregnancy was treated either by laparoscopic salpingectomy(102 patients,Group Ⅰ) or by laparoscopic oviduct fenestration(85 patients,Group Ⅱ). Results The surgical time was 40.4?9.9 min in the Group Ⅰ and 88.8?10.3 min in the Group Ⅱ.The intraoperative blood loss was 17.7?5.4 ml in the Group Ⅰ and 80.6?4.4 ml in the Group Ⅱ.The postoperative hospital stay was 3.8?0.5 d in the Group Ⅰ and 7.4?0.9 d in the Group Ⅱ.The postoperative time to normal serum ?-hCG levels was 7~14 d in the Group Ⅰ and 10~33 d in the Group Ⅱ.A follow-up was carried out in 116 patients.No recurrence of ectopic pregnancy happened in the Group Ⅰ(60 patients).In the Group Ⅱ(56 patients),hydrotubation or salpingography revealed patent oviduct in 37 patients,intrauterine pregnancy in 25 patients,and recurrence of tubal pregnancy at the same side in 2 patients. Conclusions Salpingectomy should be the first choice in the treatment of tubal pregnancy because of its short surgical time,short hospital stay,less intraoperative blood loss,and low complication incidence.Oviduct fenestration should be conducted only for patients with child-bearing demands,but we must be on our guard against the possibility of persistent ectopic pregnancy,and a salpingectomy or a conversion to open surgery should be performed immediately once the bleeding can not be stopped effectively during the operation.

OBJECTIVETo provide evidence for Chinese medical treatment of children with EB virus infection by exploring its clinical efficacy from multiple angles.
METHODSTotally 81 children patients were randomly assigned to the treatment group (46 cases) and the control group (35 cases). Patients in the treatment group took Chinese medical decoction, while those in the control received intravenous dripping of Ganciclovir and oral administration of pidotimod. The treatment period for the two groups was 2 weeks. Patients were followed-up till the 12th week. Clinical symptoms such as fever, lymphadenopathy and hepatosplenomegaly, as well as lab indices such as abnormal lymphocyte percentage, EB virus antibody, virus DNA load, T cell subsets, immunoglobulin, and so on were observed before and after treatment, at week 4 and 12 of follow-ups.
RESULTS(1) The total effective rate at week 2 was 95.6% in the treatment group, higher than that of the control group (94.3%), but there was no statistical difference between the two groups. (2) The time for defervescence, duration of pharyngeal hyperemia, duration of swollen tonsils was shorter in the treatment group than in the control group (P<0.05). The subsidence of lymphadenopathy, hepatomegaly, and abnormal lymphocytes was better in the treatment group than in the control group (P < 0.05). (3) The positive cases of peripheral blood hetero-lymphocyte was significantly reduced after treatment, at week 4 and 12 of follow-ups both in the treatment group and the control group (P < 0.01). The expression of IgA and IgM decreased after treatment in the two groups when compared with before treatment in the same group (P < 0.05, P < 0.01). IgG in the treatment group also obviously decreased after treatment, at week 4 and 12 of follow-ups (P < 0.05, P < 0.01), while it decreased only after treatment in the control group (P < 0.05). Activities of AST and ALT in the treatment group and the AST activity in the control group were markedly improved when compared with those before treatment (P < 0.05). Compared with the control group, the abnormal lymphocyte positive case number obviously decreased in the treatment group after treatment, at week 4 and 12 of follow-ups (P < 0.05). (4) After treatment, at week 4 and 12 of follow-ups, CD3+ and CD8+ significantly decreased; CD4+, CD4/CD8, and B cells significantly increased in the two groups, when compared with before treatment (P < 0.05). NK cells significantly increased more in the treatment group after treatment, at week 4 and 12 of follow-ups, higher than before treatment as well as the control group (P < 0.05). (5) EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the two groups after treatment, at week 4 and 12 of follow-ups (P < 0.05). Compared with the control group, EB viral DNA and EB viral CA-IgM negative conversion case numbers significantly increased in the treatment group after treatment and at week 4 of follow-ups (P < 0.05).
CONCLUSIONSTreatment of EB virus infection by Chinese medical treatment was effective. It could promote the recovery of EB viral infection, and reduce the risk of vicious disease after EB viral infection.
