A novel anatomical self-locking plate fixation for both-column acetabular fractures.

Purpose: To compare the stability of the posterior anatomic self-locking plate (PASP) with two types of popular reconstruction plate fixation, i.e. double reconstruction plate (DRP) and cross reconstruction plate (CRP), and to explore the influence of sitting and turning right/left on implants.

[Research advances on prenatal maternal serum markers for screening adverse pregnancy outcomes].

The routine prenatal maternal serum testing is widely used for screening of birth defects, including Down syndrome, trisomy 18 syndrome and neural tube defects. The testing results are also associated with other adverse pregnant outcomes such as fetal surface structural abnormalities, gestational hypertension disease, intrahepatic cholestasis of pregnancy, premature rupture of membranes, abortion, stillbirth, intrauterine growth restriction and macrosomia; therefore the abnormal levels of serum markers might be used for predicting these adverse pregnant outcomes.

[KCNQ1 mutation in patients with lone atrial fibrillation].

Objective: Recent studies suggest that mutation of the slow delayed rectifier potassium channel [I(Ks)] contributes to familial atrial fibrillation (FAF). In the current study, we explored the potential association between KCNQ1 polymorphism with lone AF (LAF).

Methods: Clinical data and blood samples were collected from 95 Han Chinese patients with LAF and matched healthy controls.

[Comparative study on transperitoneal retroperitoneal laparoscopic adrenalectomy and open adrenalectomy for adrenal tumours].

Objective: To compare and evaluate the clinical value among transperitoneal, retroperitoneal laparoscopic adrenalectomy and open adrenalectomy for the treatment of adrenal tumours.

Methods: From January 1996 to June 2002, transperitoneal laparoscopic adrenalectomy (TLA) was performed for 19 cases, 17 cases were successful (Group A), retroperitoneal laparoscopic adrenalectomy (RLA) for 21 cases, 19 cases were successful (Group B), during the same period 41 patients with adrenal tumours under 6 cm in diameter underwent open adrenalectomy (Group C). The procedure was evaluated and compared in the respects of tumors weight, operation time, blood loss, recovery time of GI function, hospital stay, complications transferable rate and indications among three groups.
