Analyses of optimal body mass index for infertile patients with either polycystic or non-polycystic ovary syndrome during assisted reproductive treatment in China.

We observed the effect of body mass index (BMI) on pregnancy outcomes in Chinese patients undergoing assisted reproductive treatment (ART). All the patients were divided into polycystic ovary syndrome (PCOS) group and non-PCOS group, and then according to BMI, each group was subdivided into 6 subgroups: group 1 (BMI < 18 kg/m), group 2 (18-20 kg/m), group 3 (20-22 kg/m), group 4 (22-24 kg/m), group 5 (24-26 kg/m) and group 6 (BMI > 26.0 kg/m).

Growth hormone co-treatment within a GnRH agonist long protocol improves implantation and pregnancy rates in patients undergoing IVF-ET.

Objective: The efficacy of growth hormone (GH) co-treatment within a GnRH agonist long regimen, in women with a normal ovarian response to controlled ovarian hyperstimulation (COH), for IVF was assessed.

Methods: This retrospective clinical trial was performed in a private-assisted reproduction centre. The study involved 1114 patients who responded normally to high-dose gonadotropin treatment.

Inhibitory effect of the paraoxonase gene on the formation of rabbit coronary atherosclerosis.

Objective: To observe the effect on the inhibition of coronary atherosclerosis hardening of the paraoxonase gene (PON-1) which transfected to the rabbit epicardial adipose tissue.

Methods: Rabbit coronary atherosclerosis model was established by high-fat feeding, liposome-encapsulated recombinant plasmid pEGFP-PON-1 50 μ L was injected to the rabbit pericardial cavity, and was harvested 4 weeks after transfection.

Results: The epicardial fat transfected PON-1 gene had effect on the high lipid level.

Ovarian damage after laparoscopic endometrioma excision might be related to the size of cyst.

Objective: To investigate the relationship between the size of an excised endometrioma and the magnitude of damage to the ovary after the surgery.

Design: A retrospective, controlled study.

Setting: A university hospital.

Circulating luteinizing hormone level after triggering oocyte maturation with GnRH agonist may predict oocyte yield in flexible GnRH antagonist protocol.

Background: The use of gonadotrophin-releasing hormone (GnRH) agonist for triggering final oocyte maturation and ovulation can reduce ovarian hyperstimulation syndrome (OHSS) in high-risk patients. LH levels post-trigger with GnRH agonist might be correlated with oocyte yield and maturity. Our aim was to evaluate the relationship between serum LH level at 12-h post-trigger and oocyte yield, maturity and fertilization rate in patients at high risk of OHSS and therefore who were treated with a flexible GnRH antagonist protocol in which final oocyte maturation was triggered with GnRH agonist.

[Effects of antiarrhythmic drug use on atrial fibrillation recurrence in atrial fibrillation patients post circumferential pulmonary vein ablation].

Objective: This prospective and randomize-controlled trial was designed to investigate the effects of antiarrhythmic drug use (AADs) on atrial fibrillation (AF) recurrence in atrial fibrillation patients post circumferential pulmonary vein ablation (CAPV).

Methods: Seventy-four consecutive AF patients underwent CAPV (41 paroxysmal and 33 drug refractory AF) were randomly assigned to receive placebo (Group A) or AADs (Group B) for 3 months. Monthly standard electrocardiograms (ECG) and Holter monitoring were performed to assess AF recurrences during 17 - 28 months follow-up.
