[Summary] Endometrial receptivity plays an important role in embryo implantation, and uterine fibroids is the most common benign tumor in reproductive women. In recent years, research has showed that uterine fibroids may have an effect on endometrial receptivity through the change of endometrial morphology and biochemical molecules. From the angle of effects of uterine fibroids on endometrial receptivity, this paper studied infertile patients, which may have a new idea to diagnose and treat infertility caused by uterine fibroids.

Objective To study the effect of the toothpaste containing FE enzyme on oral care to for critically ill patients with stroke. Methods Sixty cases of critically ill stroke patients were randomly divided into the experiment group and the control group with 30 cases in each group.The toothpaste containing FE enzyme was used in experiment group for oral care,and the routine oral care was used in the control group.The two groups were compared in terms of the oral cleaning effect,dental plaque and costs for the oral care.Results The incidences of bad breath,oral uncleanness and oral infection were significantly lower than those of the control group(P<0.01 or P<0.05). The dental plaque index after oral care was significantly lower in the experiment group than that in the control group(P<0.001).The cost in the experiment group was significantly lower than that in the control group(P<0.01).Conclusion Oral care using toothpaste containing FE enzymecan not only achieve an effective oral cleaning purpose,but also reduce the cost of oral care.

Objective To investigate the efficacy of active immunization combined with dydrogesterone in the treatment of recurrent spontaneous abortion,and the expression of serum leptin(LP)and adiponectin(ADPN).Methods 51 cases of inpatient and outpatient treatment of repeated abortion of 51 pregnant women from January 2014 to December 2015 in Ningbo Fenghua People's Hospital of Zhejiang Province were selected,and 50 cases of normal pregnant women and normal nonpregnant women 50 cases as a control object.Depending on the treatment method,patients with recurrent spontaneous abortion were divided into combination group(n=26)and monotherapy group(n=25).The levels of LP,ADPN and β-HCG were measured before and after treatment,and the number of successful pregnancies.Results The levels of LP and ADPN in serum were measured in three groups of women,there were statistically significant differences between the two groups(P<0.05).The serum levels of β-HCG in the pregnant women with recurrent spontaneous abortion group were(3914.5±2548.2)mIU,and the normal pregnancy group was(7124.5±2847.6)mIU,the difference was statistically significant(P<0.05).After treatment,the levels of LP,ADPN and β-HCG in the combination group were significantly increased,and successful pregnancy as high as 88.46％,better than the level of monotherapy group,the difference was statistically significant(P<0.05).Conclusion Serum LP,ADPN lower levels of pregnant women prone to recurrent spontaneous abortion,through active immunization combined with dexamethasone treatment,can significantly improve the hormone level,improve the success rate of pregnancy.

Objective To study the effect of glutamate on the expression of vascular endothelial growth factor (VEGF) mRNA and protein in cultured rat astrocytes. Methods Cultured rat astrocytes were randomly divided into 6 groups: control group (C), glutamate group (G), QA group (Q), DCG-IV group (D), L-AP4 group (L) and glutanmte-FMCPG gronp (G+M). Cells were cultured under nomoxic condition (95% air, 5% CO2). RT-PCR and ELISA methods were used to detect the expression of VEGF mRNA and protein in cultured astrocytes, respectively. G+ M group was preincubated with lmM MCPG for 30 min prior to the stimulation with glutamate. There were 7 time points at 0,4,8,12,16,24 and 48 h in each group except G+M group. Results The expression of VEGF mRNA and protein did not differ significantly among D group, L group and C group. Different from that in C group, the expression of VEGF mRNA and protein could be enhanced both in a dose-dependent and time-dependent manner in G group and Q group. Meanwhile, the enhanced expression of VEGF mRNA and protein in G group was completely suppressed by MCPG after 24 h. Conclusion Glutamate can increase the expression of VEGF mRNA and protein in cultured astrocytes, which may be due to the activation of group I metabotropic glutamate receptors in astrocytes.
