RESUMEN
Objective To discuss the value of Fisher discriminant analysis of serum progesterone and the growing rate of β-human chorionic gonadotropin in the prediction of early ectopic pregnancy. Methods 66 patients with ectopic pregnancy (11 cases were successfully treated expectantly and 55 cases were treated surgically including 40 cases of rupture of fallopian tube and 15 cases of tubal abortion) and 55 patients with intrauterine pregnancy and 50 patients with threatened abortion were chosen. Serum progesterone,β-HCG,48 hβ-HCG and the 48 h growing rate of β-HCG in each group were measured and a Fisher discriminant analysis was used. Results The serum progester-one was (30.27± 18.20) nmol/L in ectopic pregnancy group,( 108.44±23.27 ) nmol/L in intrauterine pregnancy group and (91.68±34.90) nmol/L in threatened abortion group. The first β-HCG was ( 3767.63 ± 3530.38 ) U/L in ectopie pregnancy group,(29 028.65 ± 10 874.01 )U/L in intrauterine pregnancy group and (13 457.47±16 367.65)U/L in threatened abortion group. The second β-HCG was (4349.24±3536.22)U/L in ectopic pregnancygroup,(56 139.46 ± 23 296.87 ) U/L in intrauterine pregnancy group and (23 270.63 ± 23 811.68 ) U/L in threat-ened abortion group. The growing rate of β-HCG ( β-HCG/the first serum β-HCG) was 1.29 ± 0.28 in ectopic preg-nancy group,1.93 ± 0.36 in intrauterine pregnancy group and 1.97±0.28 in threatened abortion group. There was significant difference in serum progesterone,the first β-HCG and the second β-HCG as well as the growing rate of β-HCG among the groups(P<0.05 or <0.01). Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG were connected with diagnosis of ectopic pregnancy,however,the only one serum β-HCG was not con-nected with diagnosis of ectopic pregnancy. 98.5% of ectopic pregnancy,65.6% of intrauterine pregnancy and 64.0% of threatened abortion were correctly classified in the Fisher discfiminant analysis,with overall correct rate of 77.8%. Conclusion Fisher discriminant analysis of combing progesterone and the growing rate of β-HCG can bet-ter predict the early ectopic pregnancy.

@# ObjectiveTo explore the methods of prevention and treatment of the iatrogenic biliary-tract injury.Methods22 cases with the iatrogenic biliary-tract injury were analyzed retrospectively.ResultsModified Roux-en-Y choledochojejunostomy was performed in 11 cases, end-to-end anastomosis of bile duct in 4 cases, repair of bile duct in 2 cases, a drainage of the inter bile duct and the abdominal cavity in 5 cases. Only 1 case of common bile duct injury after laparoscopic cholecystectoy was death from the toxic shock, another case of bile duct injury after conventional cholecystectoy with the drainage of abdominal cavity was death from multiple system organ failure, all of the other patients were cured.ConclusionThe iatrogenic biliary-tract injury may be causes variously, and should be discovered as soon as possible and be operated in time.
