Objective To explore the effects of the pre-pregnant body mass index(BMI) and the pregnancy growth on the mater-nal and neonatal outcomes .Methods 250 pregnant women with the built file ,regular antenatal inspection and hospital delivery in our hospital during 2011 were selected and divided into the emaciation group ,the appropriate group and the obesity group according to the pre-pregnant BMI .The occurrence rates of cesarean section ,fetal macrosomia ,low birth weight ,postpartum hemorrhage ,ges-tational diabetes ,gestational hypertension disease ,fetal distress ,neonatal asphyxia and puerperal infection were compared among the various groups .In addition ,according to the different growth amplitudes of pregnancy BMI ,the pregnant women were re-divided in-to 3 groups(weight gain insufficient group ,weight gain appropriate group and weight gain overmuch group ) and the different ma-ternal and neonatal outcomes were compared .Results The occurrence rates of cesarean section ,macrosomia ,gestational diabetes and gestational hypertension disease in the obesity group were significantly higher than those in the emaciation group and the appro-priate group(P<0 .05) ,while the occurrence rate of the low birth weight in the emaciation group was significantly higher than that of the appropriate group and the obesity group(P<0 .05);the occurrence rates of cesarean section ,macrosomia ,gestational diabetes and gestational hypertension disease in the weight gain overmuch group were significantly higher than those in the weight gain in-sufficient group and the weight gain appropriate group(P<0 .05) ,while the occurrence rate of low birth weight in the weight gain insufficient group was significantly higher than that of the weight gain appropriate group and the weight gain overmuch group (P<0 .05) .Conclusion The maternal and neonatal outcomes in the pregnant women with pre-pregnant BMI exceeding the standard and pregnant BMI overmuch growth are very worrying .The growth of pre-pregnant BMI and pregnant BMI is one of the important indi-cators for monitoring the maternal and neonatal complications .

OBJECTIVETo study the overexpression of Sox9 gene on rabbit bone marrow mesenchymal stem cells for repairing articular cartilage injury in vivo.

METHODSRabbit bone marrow mesenchymal stem cells (BMSCs) were transduced with lentivirus vector containing Sox9 gene and then cartilage specific molecule was detected by RT-PCR in vitro. Total 48 knee joints of 24 mature New Zealand white rabbits were randomly divided into 3 groups according to different defect treatment. After animals anesthesia,a full-thickness cylindrical cartilage defect of 4 mm diameter and 3 mm deep was created in the patellar groove using a stainlesssteel punch. Meanwhile, the transfected cells were implanted to repair the rabbit model with full-thickness cartilage defects. Cartilage defects tissue was observed with light microscope, electron microscope, HE and immunohistochemistry staining to assess the repair of defects by the complex at 6 weeks or 12 weeks after the implantation.

RESULTSAt 3 days after the transfection, Sox9 gene expression was highest and Sox9 gene expression decreased with the increase of time. At 3 days after the transfection, the expression of collagen type II began and reached the peak at 14 days. It showed that the bone marrow mesenchymal stem cells went into chondrogenic differentiation after transfected by Sox9 gene. Histological observation showed that at 6 weeks after the operation, the defects in the experimental group was filled with hyaline like cartilage tissue, 12 weeks after operation,the defects of cartilage and subchondral bone had satisfactory healing. Both at 6 and 12 weeks postoperatively, the defects were filled with fibrous tissues in control groups. Meanwhile, immunohistochemical staining of sections with type II collagen antibodies showed the proteins in the regenerated tissue stained positive for type II collagen and stronger than the control groups. The histological scoring system indicated that the cartilage repair of experiment groups were better than the two control groups with statistical significances.

CONCLUSIONOverexpression of Sox9 gene on rabbit bone marrow mesenchymal stem cells (BMSCs) promote the repair of cartilage defect.

The human pharyngeal microbiome, which resides at the juncture of digestive and respi-ratory tracts, may have an active role in the prevention of respiratory tract infections, similar to the actions of the intestinal microbiome against enteric infections. Recent studies have demonstrated that the pharyngeal microbiome comprises an abundance of bacterial species that interacts with the local epithelial and immune cells, and together, they form a unique micro-ecological system. Most of the microbial species in microbiomes are obligate symbionts constantly adapting to their unique surroundings. Indigenous commensal species are capable of both maintaining dominance and evoking host immune responses to eliminate invading species. Temporary damage to the pha-ryngeal microbiome due to the impaired local epithelia is also considered an important predisposing risk factor for infections. Therefore, reinforcement of microbiome homeostasis to prevent invasion of infection-prone species would provide a novel treatment strategy in addition to antibiotic treat-ment and vaccination. Hence continued research efforts on evaluating probiotic treatment and developing appropriate procedures are necessary to both prevent and treat respiratory infections.
