Background and purpose:Lung cancer is one of the leading causes of cancer death in the world. The aim of this study was to evaluate whether Fas-670 G>A and Fasl-844 T>C polymorphisms were associated with the risk of lung cancer.Methods:Data from 400 lung cancer patients with speciifc histological diagnosis were collected from 2010 to 2015. Meanwhile, data from matched healthy controls with the same gender and ±5 years were also collected. The genotypes of Fas-670 G>A and Fasl-844 T>C polymorphisms were determined by TaqMan lfuorescent probe method, and the results were analyzed using SPSS 16.0 software.Results:A total number of 386 cases and 394 controls were successfully genotyped. Compared with AA genotypeofFasgene, the GA and GG genotype carriers had no signiifcantly increased risk of lung cancer.The OR values were 1.05 (95%CI: 0.77-1.44) and 0.77 (95%CI: 0.81-1.99) respectively. Compared with TT genotype ofFasl gene, the CT and CC genotype carriers had signiifcantly increased risk of lung cancer. The OR values were 1.37 (95%CI: 1.01-1.86) and 1.74 (95%CI: 1.09-2.77), respectively. Conclusion:Fasl-844 T>C polymorphism may be involved in lung cancer risk but not Fas-670 G>A polymorphism.

Objective: To study the protective effect of vitamin E in preventing contrast-induced nephropathy (CIN) in patient with coronary artery disease (CAD) after percutaneous coronary intervention (PCI).
Methods: We prospectively studied 206 CAD patients with elective PCI in our hospital and divided them in 2 groups: Treatment group, the patients received oral vitamin E combining vinous hydration,n=102 and Control group, the patients received vinous hydration only,n=104. CIN was deifned by at 48h after contrast media injection, serum cretinin increased up to 25% from the baseline, or reached 44.2 μmol/L. Excluding the other kidney injury factors, the renal functions at 48 h before and after PCI were compared, the occurrence rate of CIN were also compared between 2 groups.
Results:①Overall, there were 19/206 (9.22%) patients suffered from CIN, the occurrence rate in Treatment group (4.90%) was lower than Control group (13.46%), χ2=4.506,P=0.034. For patients with hypertension, diabetes, chronic kidney disease, anemia and mehran risk score<10, the occurrence rate of CIN in Treatment group was lower than Control group,P<0.05.②Compared with pre-operative condition, at 48 h post-operation,Control group showed increased serum creatinine (Scr), blood urea nitrogen (Bun) and decreased creatinine clearance rate (Ccr), allP<0.05.③At 48 h post-operation, compared with Control group, Treatment group presented decreased Scr (86.72 ± 17.73) μmol/L vs (95.13 ± 21.67) μmol/L and increased Ccr (96.75 ± 27.23) ml/min vs (90.70 ± 17.85) ml/min, allP<0.05.④Multivariate regression analysis revealed that elder than 75 years of age (OR=7.278, 95% CI 5.158-11.480), diabetes (OR=3.919, 95% CI 1.330-8.200), chronic kidney disease (OR=6.325, 95% CI 2.137-16.816) and mehran risk score>10 (OR= 4.461, 95% CI 1.589-14.724) were the independent risk factors for CIN occurrence, allP<0.05.
Conclusion: Short-term application of vitamin E may reduce the risk of CIN occurrence at certain degree in CAD patients after PCI.

Objective To investigate the effects of extracellular ATP on the recovery of motor function after spinal cord injury in rats.Methods Twenty healthy adult rats were randomly divided into two groups after contusion injury was performed by the weight drop method at T10 with Allen impactor.Group A(ATP group) and group B(control group) each had ten rats.At days 1,3,7,14 and 28 after injury,the recovery of motor function after spinal cord injury in rats was assessed with modified Tarlov scores and slanting board test.Results Modified Tarlov scores and slanting board test were better in group A than in group B after spinal cord injury in rats.Significant difference was found in modified Tarlov scores and slanting board test between the two groups at days 14 and 28 after injury(P

Background Orbital fracture in children has its own characteristics.Choosing the suitable plastic materials is the effective measurement to improve the successful rate of surgery.Absorbable plate filling provides a new material for children with orbital fracture.However,few studies compare the effectivity and safety between absorbable plate filling and conventional filling.Objective The aim of this study was to compare the longterm efficacy and safety between absorbable plate and Medpor implants in the repair of pediatric orbital fracture.Methods Clinical data of 72 eyes of 72 pediatric patients with orbital fracture who received surgicals reconstruction in Beijing Tongren Eye Center from 2008 April to 2014 August were respectively analyzed,including 28 patients with absorbable plates filling and 44 patients with Medpor implants.Demography and preoperative clinical signs were matched between the two groups.Operative procedure was same except the implanted materials.The functional training of extraocular muscle was performed since the second day after surgery in both groups.The imaging findings of the orbit were evaluated by computed tomography (CT) before and after surgery.The patients were followed-up for avarage 12.7 months after operation.The therapeutic effectiveness and safety were compared between the different implants,such as incidence of enophthalmos,extraocular movement impairment and diplopia,and the sensory deficit of skin and complications were documented.Results Extraocular muscle movement improved and diplopia alleviated or disappeared in 92.9％ (26/28) in the absorbable plate group and 90.9％ (40/44) in the Medporgroup,without significant difference between the two groups (P=0.57).The sensory deficit of skin was found in 13 eyes (46.4％) and 20 eyes (45.5％ in the absorbable plate group and Medpor group,respectively,and there was no significant difference between the two groups (P =0.56).CT revealed that the anatomical reconstruction of orbits could be achieved in all patients in both groups without the shifting of implants and extrusion.No enophthalmos and postoperative infection were found in absorbable plate group,however,the residual enophthalmos or late infection was found in I eye for each in the Medpor group.Conclusions Both the absorbable plate and Medpor implants show good results for reconstruction of pediatric orbital fracture.Absorbable plate is an ideal material for pediatric orbital blowout fracture because of fewer postoperative complications.

Objective To examine the induction effects of bone marrow mesenchymal stem cells(BMSCs) transfected with bone morphogenetic protein 7 (BMP7) gene differentiating into chondrocytes. Methods We observed the phenotype of cells which were stained with alcian blue and HE climbing to the six pore plate with invert microscope. The glycosaminoglycan (GAG) value in culture medium was detected in control group,BMP7 transfect and culture medium induced groups after 7,14 and 21 days using standard curve method. Standard curve was described using galacturonic-acid as reference substance. The content of collagen Ⅱ was detected by ELISA method. Results HE and Alcian blue staining showed that BMP7 gene transfection group and the group induced by fluid possess the characteristics of chondrocyte. BMP7 induced BMSCs differentiation to chondrocyte which secrete specific protein called collagen Ⅱ and GAG. Content of GAG were (17.1±3.4),(39.5±5.4),(40.8±6.1)mg/L in control group,BMP7 gene transfected group and induced group,collagen Ⅱ were (89.7±14.3),(152.8±14.5),(155.5± 19.3)μg/L in these three groups separately. Comparing with control group,GAG and collagen Ⅱ of BMP7 gene transfected group and culture medium induced group increased obviously(all P < 0.05),but there was no significant difference between BMP7 gene transfeeted group and culture medium induced group (P > 0.05). Conclusion This active protein induces BMSCs differentiating into chondrocyte,in a level similar to that of inducing medium.

PURPOSE: The increased prevalence of dyslipoproteinemia in obese children probably contributes to the high risk of cardiovascular disease associated with being overweight. The genetic makeup is possible one of the factors that influence the impact of obesity on lipid metabolism. A relation between apolipoprotein E (Apo E) polymorphism and lipid metabolism has been convincingly demonstrated in large population. The purpose of this study was to determine whether Apo E polymorphism also influences the risk of dyslipidemia in obese children. METHODS: We studied 89 obese children with weight-for-height excess of 40% by obesity index. We measured the serum concentration of total cholesterol, triglyceride, HDL-cholesterol, LDL- cholesterol, Lipoprotein (a) (Lp(a)), apolipoprotein A (Apo A) and Apo B after overnight fasting. Apo E gene polymorphism of the 89 obese children and 30 control students were analyzed by ARMS (amplication refractory mutation system) method. RESULTS: The frequency of etsilon2, etsilon3, and etsilon4 allele were 9.7%, 82.3% and 8.0%, respectively in children. There was no significant difference between Apo E allele frequency of obese children and those of nonobese children. The serum concentrations of total cholesterol, LDL-cholesterol and Apo B were lower in etsilon2 genotype. The obese children with etsilon4 genotype had higher frequency of hypertriglyceridemia, increased level of Lp(a) and decreased level of HDL-cholesterol than other types. There was no evidence of EKG abnormality and cardiovascular complications in obese children. CONCLUSION: Our data demonstrated that obesity is associated with an increase in the risk of lipoprotein abnormalities and that the serum concentrations of total cholesterol, LDL-cholesterol and Apo B were influenced by Apo E genotypes.
