Chinese Journal of Primary Medicine and Pharmacy 2014;21(13):1933-1935
Objective To investigate the relationship between hOGG1 and XPD gene polymorphism and genetic susceptibility of gastric cancer.Methods This study was carried out in Dongying Shengli Petroleum Administration Bureau Hospital.Under the narrow band imaging(NBI) mode,the blood samples of a total of 98 gastric cancers and 80 controls without cancers were collected.Genetic polymorphisms of DNA repair genes were identified by polymerase chain reaction restriction fragment length polymorphism(PCR-RFLP),then its relationship with cancers was analyzed.Results Carrying 326Cys allele with the wine increased the risk of gastric cancer; Lys 751Gln genotype increased the susceptibility of the gastric cancers (OR =1.486,0.73 ~ 3.025).Conclusion Lys751 Gln genotype increases the risk of gastric cancer.

4.Impact of parents' occupational class and intergenerational occupational mobility on children's health in the future
Chinese Journal of Health Management 2012;(6):367-370
Objective To assess the impact of parents' occupational class and intergenerational occupational mobility on children's mental health so as to provide evidence for improving health equity.Methods Chinese general social survey 2005 (CGSS2005) dataset was used for multivariate analysis of variance (MANOVA).Results The proportion of children whose father or mother was of lowerclass occupation was 59.0% and 62.9%,respectively.When grew up,this figure dropped to 49.8%.Those whose father was in the higher-class occupational group reported better mental health status (F =1.449,P=0.015).Downward occupational class mobility experience also increased the risk of mental illness (F =3.050,P =0.048).Conclusion This study suggests an independent relationship between mental health and parents' occupational class and intergenerational occupational mobility.
5.Selective serotonin reuptake inhibitors for the treatment of ischemic stroke
International Journal of Cerebrovascular Diseases 2014;22(8):625-628
Selective serotonin reuptake inhibitors (SSRIs),a new generation of anti-depressant agent,are mainly used to treat emotional disorders in clinical practice now.Recent studies have found that SSRIs can increase neurogenesis after cerebral ischemia,promote neurovascular reconstruction,and are conducive to the recovery of neurological function.Furthermore,SSRIs can improve the tolerance of ischemic tissue,exert anti-inflammation and anti-oxidation properties,reduce the blood-brain-barrier injury,and inhibit excitatory amino acid toxicity in order to exert neuroprotective effect.This article reviews the related research progress in SSRIs and ischemic stroke.

8.Serum-free culture promotes rat adipose-derived stem cells differentiating into endothelial cells
Chinese Journal of Tissue Engineering Research 2013;(36):6443-6448
BACKGROUND:There are few reports about the effect of serum-free culture on the differentiation of rat adipose-derived stem cel s into vascular endothelial cel s.
OBJECTIVE:To investigate the isolation, serum-free culture of rat adipose-derived stem cel s differentiating into vascular endothelial cel s.
METHODS:The rat adipose-derived stem cel s were isolated from male Sprague-Dawley rats and expanded to the third passage by enzymatic digestion-adherent explants method. In the experimental group, rat adipose-derived stem cel s were cultured in serum-free medium for 24 hours. In the control group, rat adipose-derived stem cel s were cultured in low-glucose Dulbecco’s modified Eagle’s medium containing 10%fetal bovine serum. After that, the cel s were cultured in inducing medium for 3 weeks to differentiate into vascular endothelial cel s.
RESULTS AND CONCLUSION:The rat adipose-derived stem cel s grew as polygonal or fusiform-shaped adherent cel s when cultured in vitro, which could stably proliferate and passage. The rat adipose-derived stem cel s showed very low expression of CD31, a cel surface marker, after passages. After directional differentiations into vascular endothelial cel s, the cel s were pebble-shaped under the inverted microscope. Expression of CD31 was up-regulated, which was much higher in the experimental group than the control group. The induced cel s in the experimental group had stronger abilities than those in the control group to swal ow Dil-labeled acetylated low-density lipoprotein and form tube-like structures on the matrigel after differentiation into vascular endothelial cel s. So, rat adipose-derived stem cel s could be highly successful y induced to differentiate into vascular endothelial cel s in vitro after serum-free culture.
9.A meta-analysis of effectiveness of an implant-supported mandibular overdenture retained with a ball attachment
Chinese Journal of Tissue Engineering Research 2014;(47):7702-7708
BACKGROUND:There is no design that can completely rule out the intermittent impact damage to implants, therefore, a new bal attachment-retained implant system is constantly updated and developed. OBJECTIVE:To evaluate the clinical effectiveness of an implant-supported mandibular overdenture retained with a bal attachment. METHODS: We searched the Cochrane Library, PubMed, Medline, EM-base, WanFang Data, CNKI, VIP and other databases by computer to colect randomized controled trials addressing the implant-supported mandibular overdenture retained with a bal attachment and other control methods for dentures. The time limit was from database creation to February 2014. Two researchers independently completed literature screening according to inclusion and exclusion criteria, data extraction and quality assessment. RevMan 5.1 software was used for meta-analysis. RESULTS AND CONCLUSION: There were 10 studies included in result analysis, including 7 from China and 3 from other countries. Analysis results showed that statistical heterogeneity was remarkable in included studies, and there was no significant difference in patient’s satisfaction, clinical and objective indicators, and complications, suggesting that this approach continues to be explored in clinic. The implant-supported bal attachment-retained mandibular overdenture is relatively expensive, which is identical with the current research progress that is in the exploration stage worldwide. Due to the limited quantity and quality of included studies, the conclusions of this systematic review only provide references for clinical practice and research. The implant-supported bal attachment-retained mandibular overdenture stil needs further exploration and improvement.
