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.

Objective To investigate the plasma total tau(T-tau)and phosphorylated protein tau(P-tau)protein in the diagnosis of Alzheimer's disease(AD).Methods 22 352 medical patients aged over 60 years in Beichen Area Community Service Center were involved in this survey.Random sampling principle was used for screening.Mini-mental state examination(MMSE)and activities of daily living assessment form(ADL)were conducted for the cognitive function and ability of daily score firstly.When the score below the standard,the Hamilton depression scale and Hachinski ischemic scale were re-used for diagnostic score.Related laboratory tests were conducted to exclude other central nervous system and other systems and material causes of dementia patients.Ultimately,105 cases of AD,diagnosed by the neurologist,and 42 cases of non central nervous system disease,non dementia non nervous system disease patients as the normal control group were involved.T-tau and P-tau levels in the two groups were determined by ELISA.Results the T-tau concentration in AD group(15.93+6.59)ng/L was higher than control group(14.10±6.32)ng/L,no significant difference was found (P > 0.05).However,compared with control group (0.69 ± 0.24) ng/L,P-tau protein in AD group (1.26 ± 0.75)ng/L increased significantly(P<0.05).Conclusion Plasma levels of phosphorylated tau protein might have diagnostic value for AD patients.
8.An analysis on influencing factors of elders' medical consumption behavior under the back-ground of pension combined with medical service:A case study of Nanjing
Chinese Journal of Health Policy 2017;10(1):52-57
Objective: Under the background of pension combined with medical service, for the elders to reasonably, effectively and fully utilize the medical resources, it is of vital significance to establish good medical con-sumptive behavior and consumption intention, to promote healthy old age and improve elders' health and happiness to help them cultivate a fine habit in their practical life. Methods: Based on the micro-survey data of investigation in Nanjing, this paper systematically analyzed the factors influencing elders' medical consumption behavior by using the theory of planned behavior and structural equation model. Results:Different factors were classified into behavioral at-titudes, subjective norms and perceived behavior control, and significant variables were found out through behavior model as well as though measuring their relative effects. Conclusion: There is no significant casual relationship be-tween the perceived behavior control and medical consumption behavioral intention. The elders' medical consumption behavior intention is affected by various social network relationships. The belief strength, normative belief, behavioral attitudes and subject norms can affect elders' medical consumption behavior.
