PurposeTo evaluate and describe fetal cardiac development and hemodynamics high risk pregnancy by using ultrasound technique. Methods Two-hundred and thirty-three pregnancies were prospectively studied by using the detailed fetal echocardiographic procedure( fetus gestational age from 19 weeks to 39 weeks). Cardiac chamber size, internal diameter of great arteries were documented together with the presence of inflow and outflow wave patterns. In utero diagnoses of variety of congenital heart defects were also conducted. ResultsCardiac chamber size and internal diameter of great arteries showed a positive correlation with the increasing of gestational age. Left and right ventricles were demonstrated the same size during whole fetal observational period. Blood flow through mitral valve and tricuspid valve were typically 'M' type. By comparing 'e' wave and 'a' wave, this inflow blood velocity pattern was dominant by 'a' wave, though the ratio of a/e gradually decreased during the fetal development period. Blood velocity in aorta and pulmonary artery remained steady along with the gestational age. The detection rate of verity types of congenital heart diseases in this sample population was 5.7% (13 cases) ,the major problem was the complex heart malformation. The occurrence of fetal cardiac arrhythmia was 14 cases (16 % ), with the majority of atrial premature beat. Conclusions Fetal echocardiography can be used to evaluate and monitor the change of cardiac anatomy, structure and hemodymanics during the different gestational age. This has provided a new approach to the further understanding of fetal cardiac development, and is importantto the screening of congenital heart disease during pregnancy.

6 cases of gamete intra-fallopian transfer (GIFT) were performed in cooperation with the Department of Gynaecology and Obstetrics of The Third Teaching Hospital of our university in 1987. All the six women aged less than 41 years and have failed to be pregnant as long as ten years. One fallopian tube is patent at least. Two of them were pregnant after operation of GIFT. The rate of success was 33%. We used Ham's F10 medium mixed with different concentrations of fetal cord serum or mother's serum to prepare respectively follicular flushing medium (FM), sperm washing medium (SW), growth medium (GM) and transfer medium (TM). Clomiphene citrate and human menopausal gonadotropin (HMG) were used for inducing growth of follicle. HCG was given by intramuscular injection when two or more follicles were measured 16 mm in diameter by pelvic ultrasound. 32-34 hours later, follicular aspiration were performed by abdominal operation and the oocytecorona-cumulus complexes (OCCCs) were collected and trimmed under stereo microscope. The semen samples were obtained by means of masturbation 2-3 hours before operation. After centrifuged twice, the liquified semen was mixed with SW and incubated with 5% CO_2 in air at 37℃ until GIFT.The OCCCs and 25?l processed semen were loaded into a special catheter and transferred into one fallopian tube. Then the transfer procedure was repeated for the other fallopian tube. The level of HCG in blood was examined from day 11 after transfer in order to diagnose pregnancy.

Objective To investigate the effect of IL-1β-511 genetic polymorphism on postoperative analgesia with fentanyl. Methods Two hundred and fifty ASA Ⅰ or Ⅱ patients of Han nationality (native of Henan province) aged 20-50 yr undergoing elective abdominal total hysterectomy or myomectomy under general anesthesia were enrolled in this study. The polymorphic sites of the IL-1β-511 allele were analyzed by polymerase chain reaction-restriction fragment length polymorphism. The patients were assigned into 3 groups according to their genotypes: group wild homozygote; group mutation hetorozygote and group mutation homozygote. Anesthesia was induced with midazolam, remifentanil, propofol and succinylcholine and maintained with propofol, remifentanil and atracurium. The patients were mechanically ventilated after tracheal intubation. The pain was assessed using VAS score after the patients recovered from anesthesia. When VAS score was > 3 the patients were given fentany120 μg every 5 min until VAS score decreased to ≤ 3. PCIA with fentanyl was then started. The PCIA solution contained fentanyl 1.0 mg and droperidol 5mg in 100 ml of normal saline. The PCA pump was set to deliver a background infusion of 0.5 ml/h and a bolus dose of 2 ml at 5 min lockout interval. The VAS score was maintained at ≤3.The amount of fentanyl consumed during 24 h of PCIA was recorded. Results There was no significant difference in the amount of fentanyl consumed during the 24 h PCIA among the 3 groups. Conclusion IL-1β-511 genetic polymorphism is not the factor contributing to the individual variation in the patient' s response to postopertive analgesia with fentanyl, indicating that the pain within 24 h after operation is not related to the inflammatory factors.
