Objective To explore the relationship between IL-1?-511C/T and IL-1?+3953C/T site polymorphisms and the susceptibility of pediatric epilepsy.Methods Under the case-control study,IL-1?-511C/T and IL-1?+3953C/T site polymorphisms in 117 patients with pediatric epilepsy and 95 healthy individuals controls(healthy control group) were analyzed with polymerase chain reaction restriction and fragment length polymorphism(PCR-RFLP),the relationship between IL-1?-511C/T,IL-1?+3953 C/T site polymorphisms and the risk of pediatric epilepsy were analyzed.SAS 8.0 software was used to analyze the data.Results Multiple variate logistic regression analysis revealed that compared with healthy control group,there was no relationship between the IL-1?-511C/T site polymorphisms and the susceptibility of pediatric epilepsy individuals,carrying at least one +3953T variant allele(CT and TT genotypes) had a significantly increased risk for pediatric epilepsy(adjusted OR=2.46,95%CI 1.03-5.87),compared with the wild-type genotype(+3953CC).Furthermore,individuals with epilepsy or febrile seizures family history had a significantly higher risk(adjusted OR=4.12,95%CI 1.28-29.34),compared with those with both CC genotypes.Conclusions These findings support the hypothesis that IL-1?-511C/T site polymorphisms have no relationship with epilepsy,but the IL-1?+3953C/T polymorphism may contribute to the risk of developing pediatric epilepsy.

Objective To prepare and characterize the monoclonal antibodies (McAbs) against recombinant adhesion protein 33 (AP33) of Trichomonas vaginalis. Methods The purified recombinant fusion protein AP33 was used as antigen to immunize BALB/c mice. Sp2/0 myeloma cells were fused with the splenocytes from immunized BALB/c mice. After ELISA screening and 4 times of limited dilution, 5 positive hybridoma cell lines were obtained, and the biological properties of the McAbs were identified by Western blotting. Indirect immunofluorescent antibody test (IFAT) was performed and the inhibition effect of McAbs on the cytoadherence of T.richomonas vaginalis to HeLa cell was assayed. Results Western blotting demonstrated that 5 McAbs, designated as 4A2, 4F11, 4F8, 4E7 and 4H11, specifically combined with the recombinant AP33 of T.vaginalis. The McAbs were IgG1 isotypes. Four of them (4F11, 4F8, 4E7 and 4H11) showed parasite recognition by IFAT. Parasite cytoadherence to a monolayer of HeLa cells was inhibited in vitro with a inhibition rate of 50.08%, 65.03%, 50.70% and 49.08% by the 4 McAbs under a concentration of 200, 200, 400 and 200?g/ml, respectively. Conclusions The prepared McAbs against the recombinant AP33 show a protective inhibition on cytoadherence of Trichomonas vaginalis in vitro.

Objective To investigate the differences in clinical, laboratory and therapeutic aspects of primary Sjogren's syndrome (pSS) between young/middle-age group and old group.Methods The 84 pSS patients were divided into the young and middle-age group (n=54) and the old group (n = 30). The differences in clinical features, laboratory indices and drug therapy were retrospectively analyzed. The chi-square test was used for statistical analysis. Results The positive incidences of xerostomia, dry eye symptom and rampant teeth were 80.0%, 76.7% and 43.3%respectively in the old group. And they were all significantly higher than in young and middle-aged group (57.4%, 51.9% and 20.4%, all P＜0. 05). The positive rates of rheumatoid factor (RF)elevation, antiRo/SSA and antiLa/SSB antibodies were 13. 0%, 36.7% and 16.7% in the old group,and significantly lower than in young and middle-age group (44.4%, 59.3% and 42.6%, all P＜0.05). The incidences of leukopenia and thyroid gland involvement were much lower in the aged group (13.3% and 10.0%) than in the young and middle-age group (48. 1% and 37.0%, P＜0. 05). The percentage of patients receiving hydroxychloroquine as the main medicine was much lower in the aged group than in the young and middle-age group (16.7% vs. 40. 7%, P＜0. 05), while percentage of treatment with exclusive glucosides of Paeony Capsules was much higher (33.3% vs. 14.8%, P＜0.05). There were no statistical differences between two groups in ophthalmological examination,immunoglobulin level and sialography. Conclusions Those pSS patients with late onset exhibit more abnormalities in clinical parameters, but fewer in immunological parameters, which may be helpful in estimating prognosis and pathogenetic factors in pSS.

Objective To explore the impact of morphological changes of mitral valve coaptation on ischemic mitral regurgitation (IMR),and observe coaptation image of mitral valve in systole in patients with IMR by using real-time three-dimensional transesophageal echocardiography (RT3D-TEE).Methods RT3D-TEE was performed on 112 patients with IMR and 38 patients without MR as the control.Patients with IMR were divided into group of mild IMR (n =46),group of moderate IMR (n =45) and group of severe IMR (n =21),according to the severity of mitral regurgitation.Mitral valve quantification (MVQ)software of Qlab 8.1 was used for image post-processing of RT3D-TEE.The coaptation parameters was measured,included length of anterior combination(LCA3dlf),length of posterior combination(LCP3dlf),area of anterior combination(A3DTANT) and area of posterior combination (A3DTPOST) at end-systole.Then,these coaptation parameters of mitral valve were compared statistically.Logistic regression assessing was applied for analyzing the results.Results Coaptation line of anterior and posterior leaflets was almost same in normal subjects.With increasing of mitral regurgitation,a tendency to prolong in LCA3dlf and LCP3dlf were observed in IMR (P ＜0.05).Compared to that in mild and moderate IMR groups,besides A3DTANT and A3DTPOST,LCA3dlf and LCP3dlf were also increased significantly in severe IMR group (P ＜0.05).LCP3dlf was an independent correlation factor of IMR by Logistic regression analysis.The sensitivity was 73.3％ and the specificity was 94.7％ when LCP3dlf≥32 mm was regarded as cut-off point,and the area under the ROC curve was 0.949 (0.900～0.999).Conclusions Abnormal coaptation of anterior and posterior leaflets of mitral valve might be one of main cause of IMR.Involution structure of mitral valve before surgery is helpful for surgeon to select an optical surgical procedure and evaluate effects of treatment in patients with IMR.

Objective To evaluate the ablation zone and temperature changes in the liver caused by laser ablation in vitro and in vivo.Methods Single needle single point laser ablation was performed in vitro with porcine liver using 5 W and 7 W-power and in vivo with rabbit liver using 5 W-power.All energy outputs were 1 800 J.The ablation zone and temperature changes were evaluated.Results Coagulation caused by laser ablation was divided into a black carbonized area and a brown white necrotic area from inside to out,respectively.The mean in vitro ablation range obtained by 5 W and 7 W-power laser ablation was 1.9 cm × 1.2 cm × 1.2 cm and 2.5 cm × 1.5 cm × 1.5 cm,respectively.The mean in vitro black carbonized range obtained by 5 W and 7 W-power laser ablation was 1.1 cm × 0.5 cm × 0.5 cm and 1.4 cm × 0.7 cm ×0.7 cm,respectively.The average maximum temperature using 5 W-power was 243.57 ℃,62.47 ℃ and 34.27 ℃ in the ablation center,5 mm from the center,and 10 mm from the center,respectively.For in vivo liver experimentation,the average maximum temperature using 5 W-power was 62.26 ℃ and 44.35 ℃5 mm and 10 mm from the center,respectively.Conclusion Laser ablation can cause coagulation necrosis of the liver tissue in vitro and in vivo,and the ablation range increased with increasing power.Laser ablation may have potential use in the ablation of tumor localized in critical sites.

Aim To investigate the cytotoxicity of XN4 against AML cells, and the underlying mechanisms by which XN4 might induce DNA damage and apoptotic cell death through reactive oxygen species ( ROS ) . Methods The proliferation inhibition ratio of AML cells was measured by MTT. The level of extracellular ROS, DNA damage, cell cycle process and apoptosis were tested by flow cytometry ( FCM ) . Western blot was applied to test the expression of proteins. Results XN4 significantly inhibited the proliferation of HL-60 and KG1α with IC50 ( 2. 79 ± 0. 15 ) μmol · L-1 and (2. 76 ± 0. 20) μmol·L-1 respectively. XN4 signifi-cantly increased the generation of intracellular ROS, followed by inducing DNA damage and activating the ATM-γ-H2AX signaling, which led to increases of cells in the S phases of the cell cycle. Subsequently, XN4 induced apoptotic cell death through activation of caspase-3 and Parp. Moreover, the above effects were all reversed by the ROS scavenger N-acetylcysteine ( NAC ) . Conclusion XN4-induced DNA damage and cell apoptosis in AML cells are mediated via ROS generation.
