Objective To study the probability of screening the high risk people of hypercholestrolemia by cholestrol level in cord blood. Methods Cord venous blood were collected in 1000 newborns and the cholestrol and glucose level were measured. Maternal diet, birth weight and delivery time were recorded. Results The mean level of cholestrol in cord blood was (64.86?17.25) mg% in full term newborns, 42 cases were higher than 100 mg%(4.2%). No relationship was shown between the cholestrol level in cord blood and that in the mother blood or maternal ,diet or delivery time. The glucose level in cord blood was affected by what the mother eating during the 3 hours before delivery. Conclusions The cholestrol level in cord blood of full term newborns may be used as the earliest screening method for hypercholestrolemia people.

Objective To investigate the influence of previous abdominopelvic surgery on gynecological laparoscopic operation.Methods A retrospective analysis of 3 283 cases of gynecological diseases by laparoscopic operation patients in Peking University First Hospital from 2007 January to 2012 December,among them,719(21.90％) patients with previous abdominopelvic surgery history (study Group),2 564 (78.10％) patients have no history of abdominopelvic surgery (control group).Study group 719 patients,previous operation times:one time in 525 cases,194 cases were multiple; previous operation:185 cases of gynecological surgery,305 cases of obstetric surgery,108 cases of general surgery,and 121 complex surgery (include at least two kinds of surgery) ;previous operative approach:650 cases laparotomy and 69 cases laparoscopy.Compared two groups of patients with abdominopelvic adhesion and the gynecologic laparoscopic operation situation,analyzed the influence of previous abdominopelvic surgery on abdominopelvic adhesionon and gynecological laparoscopic operation.Results The incidence of abdominopelvic adhesion in the patients with previous abdominopelvic surgery was 51.2％ (368/719),which was significantly higher than that of 8.2％ (211/2 564) in patients without previous abdominopelvic surgery (P＜0.01).But the study group score (median 3) and the degree of abdominopelvic adhesion [mild 49.7％ (183/368),moderate 36.1％ (133/368),severe 14.1％ (52/368)] compared with the control group score (median 2) and degree [mild 55.0％(116/211),moderate 25.6％(54/211),and severe 19.4％(41/211)] were no statistical difference (P=0.930,P=0.684).Super-umbilical primary trocar site were chosen more common in patients with previous abdominopelvic surgery (23.1％,166/719) was significantly higher than that in the control group (3.3％,85/2 564; P＜0.01).And the rate of conversion to laparotomy was 0.6％ (4/719)significantly more than the control groups(0.l％,2/2 564; P=0.023).Compared with other groups,patients with gynecological or complex surgery or multiple operation history presented more severe abdominopelvic adhesion both in the score and degree (P＜0.01).The rate of super-umbilical primary trocar site,hospitalization time,operation time and bleeding during operation in patients with multiple operation history were significantly higher than those with single operation history (P＜0.05) ; the rate of blood transfusion,postoperative complication and conversion to laparotomy showed no statistical difference between the two groups (P＞0.05).Conclusion The laparoscopic operation could be carried out successfully and safely in patients with a history of various abdominopelvic operations,but the conversion rate increases,for patients with a history of multiple operation because of pelvic adhesion increases the difficulty of the laparoscopic operatio

Objective To evaluate the influence of different diagnostic criteria of gestational diabetes mellitus(GDM) using oral glucose tolerance test(OGTT) on pregnant outcome. Methods A retrospective study of women who delivered at Peking University First Hospital from Jan 1, 2001 to Dec 31,2003 was conducted. All women with abnormal 50 g oral glucose screening test received 75 g OGTT. Totally, there were 850 cases not being diagnosed as GDM or GIGT according to Fernando′s criteria and these women were divided to two groups according to Zhi guang DONG′s criteria: group Ⅰ included those who meet the criteria of GDM and GIGT and group Ⅱ included those who did not. Results The rate of abnormal OGTT was 23.76% (GDM 4.35%, GIGT 19.41,37 vs 165 cases). The average birth weight of group Ⅰ was significantly higher than that of group Ⅱ [(3461.4?475.9)g vs (3407.8?438.4) g, P
