Objective:To evaluate the value of controlled low central venous pressure (CLCVP) in laparoscopic hepatectomy within an enhanced recovery after surgery (ERAS) programme.Methods:Sixty American Society of Anesthesiologists physical status Ⅰ or Ⅱ patients, of liver function Child-Pugh grade A, with New York Heart Association classⅠor Ⅱ, scheduled for elective laparoscopic hepatectomy with an expected surgery time 3-5 h, were divided into 2 groups ( n=30 each) using a random number table method: CLCVP-ERAS group (group CE) and routine ERAS group (group E). In group CE, the central venous pressure was maintained less than 5 cmH 2O through using restricted fluid replacement, adjusting the position, giving the vasodilator and etc.In group E, the central venous pressure was maintained at 5-12 cmH 2O.Arterial blood samples were then collected before operation and at 1 and 4 days after operation for determination of parameters of hepatic and renal functions.The volume of fluid infused before and after liver resection, total volume of intraoperative fluid infused, blood loss, blood transfusion, duration of surgery, postoperative time to first flatus, off-bed time, length of hospitalization and total cost of hospitalization were recorded. Results:Compared with group E, the volume of fluid infused before liver resection, total volume of intraoperative fluid infused, blood loss, and blood transfusion were significantly decreased, the volume of fluid infused after liver resection was increased, the duration of surgery, time to first flatus after operation, off-bed time and length of hospitalization were shortened, and the total cost of hospitalization was reduced ( P<0.05), and no significant change was found in the parameters of hepatic and renal functions in group CE ( P>0.05). Conclusion:CLCVP is helpful for the rapid recovery of patients without obvious adverse reactions when used for laparoscopic hepatectomy within an ERAS programme.

Objective To study the current situation of reproductive tract infection among bearing age mar-fled women in countryside and influence factors. Methods We had examined 4916 women. Questionnaire investiga-tion,gynecologic examination,the inspection of pathogen and the B-ultrasound were collected by face to face in the clinic. Results The general prevalence rate of RTI was 53.93%. The prevalence rates of pelvic infection and cervici-tis were 3.97% and 51.12%. The prevalence rates of germs, trichomonal and candiclal vaginitis were 12.51%, 3.60% and 7.71% respectively. The infection rate for only one,two or three kind of RTI were 33.08% ,19.73% and 1.08% respectively. The influence factors were : age, education, family economy, sanitary habits, graviclity, frequent in-tercourse,induced abortion and knowledge towards RTI. Conclusion Among bearing age married women in country-side province the prevalence rate of RTI was higher and also showed evidence of some influence factors.
