Competing endogenous RNA (ceRNA) is a class of RNA which includes mRNA,pseudogenes,long non-coding RNA (lncRNA),circular RNA (circRNA).ceRNA weakens its inhibitory effect on mRNA translation through competitive binding with shared microRNA (miRNA).Many studies have confirmed that the disorder of ceRNA is closely related to the occur-ence of breast cancer,gastric cancer,lymphoma and other tumors.With the improvement of researches,ceRNA may be used as a tumor marker of clinical diagnosis and therapeutic target.

Based on the analysis of the existing medical service process,the paper takespatient centered as the ultimate objective,and transforms the health service process from the view of informatization including smart hospital,regional health and family health processes.The design includes the health service modes of smart hospital,family health and regional health sub-modules,and provides ideas for the achievement of wisdom medical in the future.

Objective Using mouse autoimmune premature ovary failure (POF) model to seek theoretical evidence for a possible clinical therapy of autoimmune POF with glucocorticoid (GC) or an-drogen. Methods After autoimmune POF was induced in 60 mice by Pzp3, the mice were randomly as-signed into 3 groups (n=20) : Two groups were treated with GC or androgen and the control group was treated with distilled water. We observed the changes in the sexual cycles of the mice, the serum level of AzpAb, infiltration of cells positively expressing CD45 in the ovary, and pathological alterations of the ovary. Results The sexual cycle of each therapy group was significantly different from that of the control group. The mean serum level of AzpAb of each therapy group was significantly lower than that of the con-trol group, and the mean serum level of AzpAb in the GC group was significantly higher than that of the androgen group. The percentage of growing follicles in the ovary of each therapy group was significantly higher than that of the control group. Ovaries infiltrated by cells positively expressing CD45 of each thera-py group were significantly fewer than those of the control group. Conclusion GC or androgen in mice with autoimmune POF could obviously ameliorate the pathogenetic conditions of the disorder, and both treatments have similar therapeutic efficacy.

Objective To investigate the expression and correlation of hypoxia-inducible factor-1?(HIF-1?),vascular endothelial growth factor(VEGF)and sFlt-1 in the preeclampsia placenta,and discuss their significance in the pathogenesis of preeclampsia.Methods Placentas were collected from 20 pregnant women with preeclampsia as study group and 15 normal pregnant women as control group.The expressions of HIF-1?,VEGF and sFlt-1 protein were semi-quantitatively analyzed with immunohistochemical assay and mRNA level was determined using reverse transcription polymerasc chain reaction(RT-PCR)technique. Results(1)the expression of HIF-1?and sFlt-1 protein in preeclampsia group obviously increased.Strong (+++)positive expression was observed in 9 and 11 cases respectively,significantly higher than in control group(2 and 3 cases)(P<0.05),however,VEGF expression obviously reduced in preeclampsia group(P<0.01).(2)the level of HIF-1?and sFlt-1 mRNA in preeclamptic placenta was 0.604?0.013, 0.898?0.041,significantly higher than 0.208?0.007 and 0.559?0.244 in normal placenta(P<0.05). Although the level of VEGF mRNA increased in preeclampsia placenta,it was not significantly different from that in normal placenta(P>0.05).The ratio of VEGF mRNA/sFlt-1 mRNA obviously reduced in preeclampsia group and was significantly lower than in control group(P<0.05).(3)in preeclampsia group,HIF-1?mRNA expression was positively correlated with the expression of sFlt-1 mRNA(r=0.577, P<0.05),and negatively correlated with the ratio of VEGF mRNA/sFlt-1 mRNA(r=-0.376,P<0.05).Conclusion Abnormal high HIF-1?expression in preeclampsia placenta indicates that HIF-1?might play an important role in the pathogenesis of preeclampsia,possibly through affecting the cytotrophoblastic invasion and placental vascular reconstruction via the modulation of VEGF and sFlt-1 gene transcription.
