ABSTRACT
Objective To compare the results of conservative treatment operation for two groups of tubal pregnancy with laparoscopy and laparotomy. Methods We disparted tubal pregnancy patients into two groups: laparoscopy group(418 cases from August 2001 to December 2004) and laparotomy group(182 cases from January 1998 to July 2001) ,and evaluated the clinical characteristics,the postoperative incidences of persistent ectopic pregnancy, the rate of intra-uterine pregnancy and the rate of ectopic pregnancy. Results In the laparoscopy group,only 1 case arised the postoperative incidences of persistent ectopic pregnancy. In the laparotomy group,6(3. 3% ) out of 182 arised(P 0. 05). Conclusion Laparoscopy has advantage over laparotomy therapy in the conservative operation of tubal pregnancy.
ABSTRACT
Objective: To study the absorption and utilization of dietary iron, zinc and calcium of male adults of Yi nationality, for basic information to prevent and cure diseases related to mineral deficiencies. Method: Twelve young men aged between 20 and 22 from the region lived by Yi nationality were studied in 14 d period with metabolic balance technique. At the beginning of study, their fasting blood hemoglobin and hematocrit, serum ferritin, plasma zinc and calcium concentration were deteimined. During the 4-12 d of the study, experimental diet, subsequent feces and urine samples were also collected for determining the contents of iron, zinc and calcium by flame atom absorption spectrum method, and then apparent absorption rate, apparent utilization rate and metabolic balance of these minerals were calculated. Results: The apparent absorption rate of iron, zinc and calcium was (15.8?6.2)%, (24.5?4.1)% and (32.3?9.7) % and the apparent utilization rate was (1.9?5.7)%, (12.8?4.3)% and (5.5?15.9)% respectively. The metabolic study showed iron balance, and zinc balance, but calcium balance was variable. Conclusion: The intakes of iron and zinc from the diet can meet the requirements, but calcium cannot. More intakes of foods rich in calcium are recommended for Yi nationality.
