Sidewall cerebral aneurysms: effect of an outflow angle-assisted approach on diagnosis.

Background: The ability to diagnose sidewall cerebral aneurysms (SCAs) on an angle measurement basis may be useful in clinical practice. A study was undertaken to evaluate the effect of an outflow angle (OA)-assisted approach.

Methods: MR angiography (MRA) images of 438 patients with suspected SCAs and other cerebrovascular diseases were separately evaluated using the subjective approach and the OA approach.

[Effects of electroacupuncture intervention on changes of quality of ovum and pregnancy out- come in patients with polycystic ovarian syndrome].

Objective: To observe the effect of electroacupuncture (EA) treatment on the quality of ovum, stem cell factor(SCF) and the pregnancy outcome in patients with polycystic ovarian syndrome (PCOS), so as to explore its mechanism underlying improving pregnancy rate.

Methods: A total of 200 PCOS patients undergoing in vitro fertilization-embryo transplantation (IVF-ET) were randomly divided into control (medication) group (n = 98) and EA group (n = 102). For patients of the EA group who were undergoing controlled ovarian hyperstimulation, EA stimulation (5 Hz/20 Hz, 15-20 V) was applied to bilateral Shenshu (BL 23), Qihai (CV6), bilateral Zusanli (ST 36)-Sanyinjiao (SP 6), and bilateral Neiguan (PC6)-Zigong (EX-CA 1) for 30 min, once daily till accepting embryo transplant.
