Objective To explore the association between cytotoxic T lymphocyte associated antigen-4 (CTLA-4) gene polymorphism and susceptibility to ankylosing spondylitis (AS). Methods The case-control studies from Chinese Biomedical Database, Chinese National Knowledge Infrastructure, Wanfang, Weipu, PubMed, Cochrane Library, OvidSP, Wiley Online Library, Elsevier Science Direct, Springer Link databases for the association of CTLA-4 gene polymorphism with AS. The association strength was assessed with chi-squared test by Stata 12.0 software. Results Seven references of CTLA-4 gene +49A/G (rs231775) polymorphism were enrolled which included 1119 AS patients and 995 controls (healthy subjects or non-AS patients), which showed that there were no statistical difference between AS and control groups under recessive, dominant, co-dominant, additive and allele gene models. Five references of CTLA-4 gene-318C/T (rs5742909) polymorphism were enrolled which included 635 AS patients and 512 controls, which showed that there were no statistical difference between AS and control groups under recessive and additive gene models; however, there were statistical difference between AS and control groups under dominant model [ OR=1.651, 95%CI (1.052, 2.590), P=0.029], co-dominant model [OR=0.621, 95%CI (0.403, 0.957), P=0.031] and allele model [OR=1.587, 95%CI (1.068, 2.357), P=0.022]. Conclusion The meta analysis reveal that CTLA-4 gene rs231775 single nucleotide polymorphism is not associated with the susceptibility to AS; rs5742909 SNP is associated with the susceptibility to AS, which suggests that C→T mutation increases the risk of AS.

ObjectiveTo explored the relationship among endothelin-1(ET-1), P-selection and troponin I(CTnI) in acute myocardial infarction (AMI) and unstable angina (UA).MethodsPlasma level of endothelin-1 was analyzed by radioimmunoassay, the expression of P-selection was analyzed by flow cytometery technique and troponin I was analyzed by paramagnetic partile chemiluminescent immunoassay in 23 AMI cases, 21 UA cases and 28 healthy controls.ResultsPlasma levels of ET-1 and CTnI in AMI patients were higher than in controls(P<0.05). The expression of P-selection in AMI patients was higher than in controls (P<0.01).Plasma levels of ET-1 and expression of P-selection in UA patients were higher than in controls (P<0.05). There was an increased trend of CTnI in UA patients in contrast to controls, but without statistical significance(P>0.05).As compared with UA, plasma levels of CTnI and expression of P-selection were elevated in AMI patients (P<0.05). No significant difference was observed between AMI and UA cases in plasma level of ET-1. Multivariate regression analysis revealed that P-selection was significantly associated with AMI and UA cases compared with plasma level of CTnI (r=0.404,P<0.01).ConclusionsPlasma levels of ET-1 and P-selection were sensitive markers as prethrombolic status.

Objective:To observe the effect of etanercept on bleomycin-induced pulmonary fibrosis in mice and its possible mechanisms.Methods:Thirty male SPF Kun ming mice were randomly assigned to control group ( intratracheal saline injection ) or model group ( intratracheal injection of bleomycin 5 mg/kg ) or intervention group ( intratracheal bleomycin injection followed by etanercept 3 mg/kg intraperitoneal administration twice a week )(n=10 group).Lung tissue were taken after the sacrifice of the mice with 28 days of molding.The content of hydroxyproline of the right lung samples was measured by alkaline hydrolysis method ,while the left lungs were fixed in 4%paraformaldehyde and embedded in paraffin with the sections stained with hematoxylin -eosin or Masson′s trichrome for pathological examination .Total tissue protein was extracted from lung homogenates to detect the expression of NF -κB and phosphorylation of NF-κB( P-NF-κB) by Western blot.Results:The content of hydroxyproline in lung tissue of mice of intervention arm was decreased significantly compared with the model arm ( P<0.01 ).The alveolar structure of the intervention arm maintained integrity with alveolar septum slightly thickened.The inflammation and fibrosis scores were decreased significantly with noticeable greater improvement of pulmonary fibrosis than the model arm (P<0.01).In addition,the protein phosphorylation of NF-κB in the lung tissues was remarkably decreased in the intervention arm ( P<0.01 ).Conclusion: Etanercept can inhibit the phosphorylation of NF-κB and reduce lung inflammation and fibrosis caused by bleomycin in mice ,which may be useful in the treatment of pulmonary fibrosis.

BACKGROUND: The preventative capabilities of enamel demineralization, rising from the fixed orthodontic treatment, have drawn tremendous attention in recent years. Despite a variety of investigations carried out by both domestic and foreign scholars, whereas, the results of ways to reduce the incidence of demineralization are never fully satisfactory or unified. OBJECTIVE: To evaluate the inhibitory effect of Fluor protector on enamel demineralization based on clinical practices during fixed orthodontic treatment.DESIGN, TIME AND SETTING: Contrast observation was performed in the Department of Stomatology, Qingdao Second Sanatorium, Jinan Military Area Command of Chinese PLA from January 2006 to January 2009. PARTICIPANTS: A total of 132 participants (856 teeth, aged 7-18 years, average age 10.5 years, 76 females and 56 males), who had wall-developed hardened dental tissues, no tetracycline pigmentation teeth, no dental fiuorosis, or anything that constricted in their teeth, were involved in the study. And all subjects were volunteers who had signed the informed consent form and agreed to receive dental treatment and periodic review.METHODS: All the teeth were randomly divided into two groups: experimental and control groups. Teeth for the experimental group were bonded with the supporting brackets with the Fluor protectors, whereas teeth for the control group did basically the same only without the Fluor protectors. After the fixed orthodontic treatment, the supporting devices were removed, all the teeth were fully washed, and then the conditions of the tooth surfaces were observed and documented in both experimental and control groups.MAIN OUTCOME MEASURES: The detection rate of orthodontic enamel demineralization in the two groups alter the fixed orthodontic treatment.RESULTS: After evaluation of the results of both groups, the incidence rate of enamel demineralization in the experimental group (5.51%) was obviously lower than control group (15.1%).CONCLUSION: Fluor protector has a significantly positive effect on preventing enamel demineralizaUon dudng fixed orthodontic treatment.

Objectives: To explore the association between the polymorphism in -857 site of tumor necrosis factor (TNF)-α promoter region and the susceptibility to ankylosing spondylitis (AS). Methods: Case-control studies Pubmed, Cochrane Library, Ovid, Chinese Biomedical Database(CBM), Chinese National Knowledge In-frastructure(CNKI), Wanfang and Weipu data bases from inception to October 2013 for the association between TNF-α-857 C/T polymorphism and the susceptibility to AS were collected. Meta-analysis was performed by Revman 5.2 and Stata 12.0 software. Pooled odds ratios (ORs) with 95% confidence intervals (CIs) were de-rived from random-effects or fixed-effects models to assess the strength of the association. Results: Nine case-control studies were included in the final meta-analysis, including a total of 933 AS patients and 1094 controls. Statistically significant differences between AS and control groups were observed in the susceptibility to AS and TNF-α-857 genotype CC [OR=0.46, 95%CI (0.26, 0.81), P=0.007], allele C [OR=0.61, 95%CI (0.41, 0.91), P=0.02] and T [OR=1.64, 95%CI (1.10, 2.43), P=0.02]. But, no statistical difference in the fre-quency of genotype TT [OR=1.49, 95%CI (0.95, 2.34), P=0.08] was observed between AS and control groups. There were obvious heterogeneities among the studies of genotype CC(P<0.00001, I2=87%), allele C(P<0.00001, I2=84%) and allele T(P<0.00001, I2 =84%), except genotype TT(P=0.09, I2=42%). Sensitivity analysis was per-formed by leaving out one study at a time, but the heterogeneity remained obvious. It was symmetric of the funnel plots of genotype CC, allele C and T with AS, but genotype TT. There was no statistical significance in genotype CC[Begg′s test(z=0.52, P=0.602), Egger′s test(t=0.23, P=0.825)], genotype TT[Begg′s test(z=0.94, P=0.348), Egger′s test(t=1.26, P=0.248)], allele C[Begg′s test(z=0.31, P=0.754), Egger′s test(t=0.72, P=0.494)] or allele T[Begg′s test(z=0.31, P=0.754), Egger′s test(t=-0.72, P=0.494)]. Conclusions: Genotype CC, allele C and T of TNF-α-857 are associated with the susceptibility to AS, and T-allele carriers have higher risk of AS.

Objective To evaluate retrospectively whether posterior longitudinal ligament(PLL)adhere to dura mater in the patients with cervical spondylotie myelopathy(CSM)or not before the anterior cervical operation.Methods From December 2005 to January 2007,of 18 patients with CSM the adhesion between PLL and dura mater was found in the anterior cervical operation.The patients included of 11 males and 7 females,with mean age of 65.4 years (range 55-72 years).All the patients were measured by CT and MRI before operation.There were 12 cases of dual-segmental cervical intervertebral disc herniation,6 of tri-segmental disc herniation.The former cases were treated with one level corpectomy and titanium mesh or iliac grafting and cervical anterior plate,and the latter with an additional cervical cage in the intervertebralspace.The floatation method was used to deal with the adhesion.The fitness between the two radiological methods was analyzed by matched-pairs Kappa eoemcient test.Results The nerve functions of all the patients were improved after anterior cervieal decompression.The mean score of JOA was increased from 9.6 of pre-operation to 12.1 of post-operation.There were 4 cases with injury in dura mater,which healed after appropriate dealing with the leakage of cerebrospinal fluid.None of lacerated dura was directly repaired during the operation.The condition of the coarse touch and bur between intervertebral disc and dura mater were found in CT transverse scanning.The thickening of the PLL and the unsymmetrical space between inferior and superior subdural cavity was found in MRI.The coefficient test proved that the difference of the CT and MRI was significant in finding the adhesion.Conclusion MRI iS better than CT in finding the adhesion between the PLL and dura mater in CSM before operation,besides the floatation method should be good to deal with the adhesion.

Objective To explore the effect of addition and subtraction of Xiaojiyinzi prescription in the treatment of bleeding after bipolar vaporization of prostate for benign prostatic hyperplasia.Methods From June 2013 to June 2017,90 patients with benign prostatic hyperplasia who underwent bipolar electrovaporization in the Traditional Chinese Medicine Hospital of Wenling were selected in this study.The patients were divided into observation group and control group according to a random number table,with 45 cases in each group.The observation group was givenaddition and subtraction of Xiaojiyinzi prescription,while the control group was treated with finasteride orally.The clinical effects of the two groups were compared and analyzed.Results The amount of bleeding in the control group at 3 days,5 days and 7 days after operation were (13.69 ± 1.27) mL,(8.37 ± 1.23) mL,(6.13 ± 0.58) mL,respectively,which in the observation group were (9.22 ± 1.18) mL,(6.12 ± 0.98) mL,(3.98 ± 0.33) mL,respectively,there were statistically significant differences between the two groups (t =17.297,P =0.000,t =9.597,P =0.000,t =21.613,P =0.000).The amount of bleeding in both two groups decreased with the prolongation of time,and the differences were statistically significant between each two moments (all P ＜ 0.05).After treatment,the I-PSS and NIH-CPSI scores in the control group were (13.22 ± 2.95) points and (13.64 ± 4.22) points,respectively,which in the observation group were (8.11 ± 1.35) points and (7.88 ± 3.06) points,respectively,which were lower than those before treatment,and the differences were statistically significant(t =12.286,P =0.000,t =14.359,P =0.000,t =21.041,P =0.000,t =25.989,P =0.000).The scores in the observation group after treatment were lower than those in the control group,and the differences were statistically significant between the two groups (t =8.217,P =0.000,t =7.413,P =0.000).Conclusion Hemorrhage is the most common complication of transurethral resection of prostate in elderly men,which seriously interferes with postoperative recovery.The addition and subtraction of Xiaojiyinzi prescription can reduce bleeding and improve postoperative recovery.
