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.

Stroke is the leading cause of death and major cause of diability in China, but with few effective therapies. As few as 3%-5% of ischemic stroke patients have access to drug treatment with tissue plasminogen activators, and no drug treatment is available to patients of hemorrhagic stroke. Stem cell therapy has been proposed as a potential regenerative strategy for stroke patients. In the future, stroke stem cell research can be combined with genetic editing, 3D and other emerging technologies or drug treatments, to promote the development of stroke stem cell regenerative medicine. Based on the guidelines for stem cell research of stroke, this review elaborates on the action mechanism and clinical reasearch of stem cells for the treatment of stroke, including neural stem cells (human neural precursor cell line NT2/D1 and human immortalized neural stem cell line CTX) and adult stem cells (bone marrow mononuclear cells, mesenchymal stem cells, and multipotent adult progenitor cells), while disclosing the limitations of stem cell therapy. In the future, stem cell research in stroke can be combined with gene editing technology and drug treatment to improve the safety and effectiveness of stem cell therapy in the hope of promoting the research of regenerative medicine for stroke.

?AlM: To evaluate the relationship of early-life and childhood exposures and age-related cataract ( ARC ) , and provide a scientific evidence for early preventing, treating and detecting ARC.
?METHODS: A hospital-based case control study was conducted from April 2011 to October 2012. A total of 360 cases ( 360 eyes ) aged 41 ~ 60 years old for cataract extraction and 360 frequency-matched controls in the same hospital for various not related to ARC were included in the study. A structured interviewer -administrated questionnaire that included information on sociodemographic characteristics, early - life and childhood exposures was used. The risk factors of ARC were estimated with unconditioned logistic regression models.
?RESULTS:Early gestational age at birth sooner and lower birth weight was significantly associated with the risk of ARC(OR=1. 152,95%CI:1. 029~2. 235,P=0. 024;OR=1. 374, 95%CI:1. 156 ~2. 581,P=0. 037,respectively). The maternal pre-pregnancy diabetes ( OR=1. 587, 95%CI:1. 177~2. 915,P=0. 019),gestational diabetes (OR=1. 763, 95%CI:1. 375 ~ 2. 367,P= 0. 004), preeclampsia(OR=1. 581, 95%CI: 1. 139 ~1. 996,P=0. 021), and pregnancy induced hypertension (OR=1. 517, 95%CI:1. 032~1. 963,P=0. 024) could make the risk of ARC increased. Of the factors affecting the period of children, only shorter height relative to peers and overweight at age 10 were significantly associated with the risk of ARC( OR=1. 329, 95%CI:1. 072~2. 351,P=0. 038;OR=2. 302, 95%CI:1. 323~3. 196,P=0. 011, respectively).
?CONCLUSlON:Early gestational age at birth, low birth weight, the maternal pre - pregnancy diabetes, gestational diabetes, preeclampsia, and gestational hypertension, and shorter height and overweight relative to peers, at age 10 were risk factors of ARC. But lasted long large and prospective studies are needed to insure early risk factors for ARC in the Chinese population.

Objective To study the influence of valproate sodium(VPA)on neuroprotective effects of topiramate(TPM).Methods For-ty-eight 3-4 week-old male Wistar rats were randomly divided into 4 groups of 12 rats each.Group A was negative control rats,and groups B-D were rat model of epilepsy,induced by pentylenetetrazol(PTZ).The rats in 2 experimental groups were adminstered intragastrically with TPM 40 mg/kg and TPM 40 mg/kg+ VPA 200 mg/kg;2 control groups(groups A and B)with the equal amount of distilled water administration.After 2-month administration,changes of the behavior,levels of serum neuron-specific enolase(NSE)and the pathological in hippocampus were examined.Results The level of NSE in the group of TPM were significantly lower than that in masculine group,but no difference between masculine group and the TPM plus VPA.The pathological change in hippocampus were abatement in the group of TPM.Conclusion TPM plus high dosage of VPA will impaire the neuroprotective effects of TPM.

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.

Objective To investigate the influence factors of central venous catheter related infections (CVC-RI) in postoperative patients with gastric carcinoma treated with parenteral nutrition,in order to provide scientific basis for prevention and treatment.Methods Using the retrospective study method,150 patients who treated with parenteral nutrition after operation of gastric carcinoma from December 2013 to March 2014 were selected.Information including age,sex,anamnesis,catheter indwelling time,infusion rate of nutrient solution,and so on were collected.Patients with central venous catheter related infections were set as infection group,patients without infection as the control group,and the group logistic regression analysis was used to analyze the collected data.Results 21 patients in infection group had CVC-RI,and the incidence was 14.00％ (21/150),while 129 patients in control group had CVC-RI.Univariate analysis showed there was significant difference between infection group and control group in age,anamnesis,catheter indwelling time and infusion rate of nutrient solution (x2=17.126,5.447,12.795,7.973,P＜0.05),however there was no significant difference in sex,health insurance,the success rate of catheterization and whether glutamine was in nutrient solution (P＞0.05);the group logistic regression analysis showed that age (OR=15.927,95％CI 3.305-76.756,P＜0.05)and catheter indwelling time (OR=3.511,95％CI 1.028-11.992,P＜0.05) were independent risk factors for CVC-RI,however infusion rate of nutrient solution (OR=0.140,95％CI 0.033-0.597,P＜0.05) was a protective factor.Conclusions For the postoperative patients with gastric carcinoma treated with parenteral nutrition,CVC-RI is closely related to age,catheter indwelling time and infusion rate of nutrient solution.So reducing catheter indwelling time,restoring the enteral nutrition under condition permission as so on as possible can reduce infection of elderly patients.
