Objective To study the protective effect and mechanism of lactulose on the renal function in acute cholelithiasis with obstructive jaundice. Methods Fifty five cases of acute cholelithotic obstruction were randomly assigned into lactulose group (group L, n=28) and control group (group C, n=27), and 50% lactulose (group L)or 10% glucose (group C ) was administered orally for 3 days before the operation , respectively. The systemic and portal blood endotoxin (ET), blood urea nitrogen (BUN) and endogenous creatinine clearance rate (Ccr) were measured periodically. Results (1) In group L, the level of systemic vein ET and BUN were significantly lower than that in group C (P0.05); and the systemic vein ET and Ccr decreased significantly on 9d (P

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 investigate the radiobiological effects of radiation with different dose rates on human nasopharyngeal carcinoma cell line CNE-2 treated with or without a poly ADP-ribose polymerase (PARP) inhibitor,olaparib.Methods The concentration of olaparib used to treat cells equaled to the inhibition concentration IC10 of olaparib to CNE-2 cells.The CNE-2 cells were divided into acute radiotherapy (RT) group,fractionated radiotherapy (FRT) group,olaparib + RT group,and olaparib + FRT group.All groups were exposed to radiation of 0,1,2,3,5,7,and 10 Gy at a dose rate of 3 Gy/min.The delivery time for each dose point was 4 min in RT and 30 min in FRT.The colony forming assay was used to evaluate the survival of CNE-2 cells at each dose point.The multi-target,single-hit model was used to fit the cell survival curves and the parameters,D0,Dq,and SF2,were calculated.At dose points of 0.1,and 2 Gy,western blot was used to determine the expression of PARP-1 in the RT group and the FRT group and γH2AX in each group.Immunofluorescence was used to evaluate the γH2AX focus formation.A single factor analysis of variance was used to compare the 4 groups,and two two compared with SNK-q test.Results The IC10 value of olaparib to CNE-2 cells was 4.0 μmoL/L.At dose points of 1 and 2 Gy,the PARP-1 expression was significantly higher in the FRT group than in the RT group (P=0.029,0.022),while the γH2AX focus number was significantly smaller in the FRT group than in the other three groups (all P<0.05);compared with the RT group,the D0,Dq,and SF2 values in the FRT group were increased by 11.67%,15.78%,and 23.61%,respectively;compared with the FRT group,the D0,Dq,and SF2 values in the Olaparib+ FRT group decreased by 11.19%,6.44%,and 13.26%,respectively;there were no significant differences in above indices between the RT group,the Olaparib+RT group,and the Olaparib+FRT group.Conclusions For the same radiation dose,fractionation reduces the relative dose rate and weakens the radiobiological effects.lowdose olaparib can compromise the single strand break repair induced by the decline of the relative dose rate in a fractionated irradiation mode,which promotes the formation of double-strand break and improves the radiobiological effects.

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.

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.
