Objective To explore the effect of flushing uterine cavity with metronidazole solution at different temperatures on postpartums with high risk of infections during cesarean section.Methods One hundred and two puerperas with high risks of infections undergoing caesarean section were randomized according to random sampling into three groups equally.Groups A,B and C were treated with uterine cavity flushing with metronidazole solution at three temperatures of 22~24℃,39~40℃and 37.5~37.8℃respectively.Comparisons were done between the three groups in terms of vaginal bleeding 2h after operation,heart rates 15 min before operation and 15 min after operation and the temperatures.Results The differences in temperature and heart rate 15 min after operation were significantly different arnong the groups(P<0.05).The temperature and heart rates of group A were higher and faster than the other two groups(both P<0.05)but no differences between group B and group C(P>0.05).In group A,the temperature and heart rate after operation were significantly lower and faster than those before operation(P<0.05),while there were no differences within group B and C respectively (P>0.05).The vaginal bleeding volume 2 h after operation in groups A and B was significantly more than group C(P<0.05)and that of group B was significantly smaller than group A(P<0.05).Conclusion Uterine cavity flushing using metronidazole at the temperature of 37.5~37.8℃after cesarean section can reduce postpartum hemorrhage and relieve patient’s discomfort.

OBJECTIVEBy observing the adipogenic and angiogenic microenvironment impact on the morphology of newly generated tissue for exploring the key factors which inducing mature adipose tissue regeneration in tissue engineering model.

METHODS24 healthy 6 months' New Zealand rabbits were picked and put into four groups according to different microenvironment. Every group has 6 rabbits and divided as follows: no axial-blood supply fat flap(0 ml), granular fat only(0.6 ml), axial blood vessel only (0.05 ml), axial vascularized fat flap ((0.6 ml). We separated or combined adipogenic and angiogenic environment within these groups. After 8 weeks, samples were harvested for histologic observation including macroscopic observation, volume analysis and HE testing.

RESULTSIn granular fat group, its volume decreased by (0.25 ± 0.10) ml after 8 weeks as the shortage of blood supply and finally it could be enveloped. In axial blood vessel group, its volume increased by (0. 37 ± 0. 04) ml after 8 weeks with fibrous tissue formation as shortage of adipogenic microenvironment. The no axial-blood supply fat flap group grew into(0.12 ± 0.03) ml, which can' t support large volume adipose tissue formation because of lacking independent blood supply. Only axial vascularized fat flap model could generate mature adipose tissue in large volume(3.45 ± 0.48) ml. The number of new capillary in every group was different after 8 weeks. By counting the numbers in every single view, no axial-blood supply fat flap group 15 ± 3.5)and granular fat only group(5 ± 2.5)had a significant difference with axial vascularized fat flap group 22 ± 5) respectively.

CONCLUSIONOnly both adipogenic or angiogenic microenvironment exist could induce mature adipose tissue in large volume in tissue engineering chamber model.

Objective:To differentiate human embryonic stem cells ( hESCs ) into keratinocytes ( K-hESCs) and analyse the expression characteristics of biomarkers of K-hESCs.Methods: The hESCs of line H9 were seeded on matrigel in mTeSR1 medium.The hESCs were directly differentiated into kerati-nocytes in epithelial differentiation medium with bone morphogenetic protein 4, retinoic acid and N2 sup-plement.The karyotype of K-hESCs was analyzed, comparing the gene expression differences of K-hESCs with human gingival epithelial cells (HGECs), human immortalized oral epithelial cells (HIOECs) and HaCaT by Real-time PCR.Molecular characteristics of the cell differentiation were observed throughout the process by immunocytochemical techniques.Results:H9-hESCs were successfully differentiated into the cells that exhibited characteristics of keratinocytes in epithelial differentiation medium.The karyotype of K-hESCs was 46, XX; and the keratinocyte gene p63 expression in K-hESCs was significantly lower than that in HaCaT ( P<0.05) , but there was no significant difference of p63 expression in K-hESCs, comparing with that in HGECs and HIOECs ( P >0.05 ) .Conclusion: H9-hESCs could be directly differentiated into K-hESCs.The gene expression of K-hESCs was similar to that of epithelial cells in the early stage of monolayer cells differentiation with high proliferative activity.

Akebia trifoliate has been reported to have many pharmacological activities and the roots, petioles and seeds are used to different symptoms. However, the structure and anatomy of its seeds was almost not reported until now. In the present study, we investigated the morphological characters of the fruit and seed, and the anatomical characters of the testa, micropyle, embryo and endosperm, which could provide evidences for the study on classification, identification and application of A. trifoliate. Our results showed that the testa of A. trifoliate consisted of an epidermic cell layer, the sclerenchyma cells layer, the parenchyma cells layer and an innermost pigment layer. At the micropylar region, the outermost epidermal cells were specialized the white caruncle-like structure and the testa included a lot of lignified tissues. Endosperm comprises two layer cells. Outermost yellowish-brown layer cells contains lots of fat droplets, and innermost white layer cells contains lots of aleurone grains and crystalloids.
