Differentiation of Rat Bone Marrow Mesenchymal Stem Cells Into Neuron-Like Cells In Vitro and Co-Cultured with Biological Scaffold as Transplantation Carrier.

BACKGROUND Autograft and allograft transplantation are used to prompt the regeneration of axons after nerve injury. However, the poor self-regeneration caused by the glial scar and growth inhibitory factors after neuronal necrosis limit the efficacy of these methods. The purpose of this study was to develop a new chitosan porous scaffold for cell seeding.

Acceptance and Continuation of Contraceptive Methods Immediate Postabortion.

Background/aims: Providing preabortion contraceptive counseling for the method of contraception may reduce the incidence of repeat abortions. This study aimed to compare the acceptance and continuation rates of intrauterine devices (IUDs), combined oral contraceptives (COCs), and condom use after abortion in women who received preabortion contraceptive counseling.

Methods: Women seeking a first-trimester abortion prospectively received preabortion contraceptive counseling and the choice of method of contraception was based on the counseling and not related to prior methods of birth control.

Differences in 23S ribosomal RNA mutations between wild-type and mutant macrolide-resistant isolates.

The aim of the present study was to determine the susceptibility of wild-type and mutant clinical isolates of strains to erythromycin, azithromycin and josamycin, and to identify the resistance-conferring 23S ribosomal (r)RNA mutations in the isolates. The wild-type resistant isolates were defined as those with minimum inhibitory concentration values above the tissue concentration of the antibiotic in the urogenital system. Furthermore, all resistant isolates were exposed to sub-inhibitory concentrations of macrolides, and 13 resistant mutants were selected following serial passages.

Termination of second-trimester pregnancy by mifepristone combined with misoprostol versus intra-amniotic injection of ethacridine lactate (Rivanol®): a systematic review of Chinese trials.

Background: Mifepristone combined with misoprostol for second-trimester abortion (MM) and intra-amniotic injection of ethacridine lactate (EL; Rivanol®) are the common methods for termination of second-trimester pregnancy in China. The systematic review of relevant literature was conducted to evaluate the effectiveness and safety on termination of second-trimester pregnancy using MM, introduced in 1988 in China, versus the Chinese routinely used method since 1970 -- EL. The review was conducted to evaluate mifepristone combined with the misoprostol versus intra-amniotic injection of ethacridine lactate in China for termination of second-trimester pregnancy with respect to efficacy, side effects, complications and so on.

Mifepristone in combination with prostaglandins for termination of 10-16 weeks' gestation: a systematic review.

Objectives: Medical regimens using mifepristone in combination with prostaglandins have been widely available for women undergoing termination of pregnancy (TOP) at 10-16 weeks' gestation in China. We undertook a systematic review to compare different regimens of mifepristone with prostaglandins for TOP at 10-16 weeks' gestation.

Methods: We searched multiple electronic databases for English and Chinese language reports (1990-2007) including MEDLINE, the Cochrane Library and the Chinese Biomedical Literature Database.
