ABSTRACT
Objective To study the impacts of leukocytes elevation on the sperm quality and oxidative stress .Methods A total of 52 elevated leukocytes specimen and 50 normal leukocytes specimen were collected .Standard semen analysis was performed .Re-active oxygen species (ROS) production was measured using luminol as the probe by the Chemiluminescence method .Malonalde-hyde(MDA) content in semen was measured by the sulfo-barbitone acid method .Total superoxide dismutase(T-SOD) in semen was measured by the xanthine oxidase method .Results The semen parameters including total motility (P= 0 .008) ,progressive motility (P= 0 .005) and normal forms (P= 0 .003) ,the sperm motion parameters including mean curvilinear velocity (VCL)(P= 0 .023) , mean straight-line velocity (VSL)(P= 0 .010) ,mean average path (VAP)(P= 0 .011) ,swing(WOB)(P 0 .05) .Conclusion The leukocytes elevation could result in the decrease of spermatozoa quality ,which might be related with ROS increase .
ABSTRACT
Objective To investigate the effects of two biovars of ureaplasma urealyticum on leukocyte concentration and sperm motion parameters.Methods Sperm motion parameters were analyzed with computer-aided sperm analysis (CASA).Leukocytic number of semen was measured with benziding-perxidase staining.Culturing and real-time polymerase chain reaction (RT-PCR) was used to identify biovars of U.urealyticum in the semen.Results Sperm motion parameters including mean curvilinear velocity (VCL), mean straight-line velocity (VSL), mean average path (VAP) , and mean beat Cross frequency (BCF) showed significant difference between infertile and normal group (P ＜0.05).Biovar Ⅱ infected men displayed significant increase in leukocyte counts (P ＜ 0.001).When compared to uninfected group,the sperm motion parameters showed significant decreases of VCL, VSL, VAP, mean percentage lineality (LIN), and swing(WOB) in biovar Ⅱ (P ＜ 0.05).Conclusions Biovar Ⅱ has closer relationship with leukocyte elevation and sperm motion impairment.
ABSTRACT
Objective To investigate the relationship between the interleukin-17 (IL-17),interleukin23 (IL-23) and carotid artery sclerosis in patients with cerebral infarction.Methods One hundred and twentyfive cerebral infarction patients in the first affiliated hospital of Shantou University medical college from June 2010 to June 2012 were recruited.All the subjects were examined with carotid ultrasonography.According to the results of carotid ultrasonography,all patients were divided into carotid atherosclerosis group(86 cases) and non carotid atherosclerosis group(39 cases).Patients with carotid atherosclerosis were divided into soft plaque group (35 cases),hard plaque group (21 cases),mixed plaque group (30 cases) based on plaque feature.Carotid atherosclerosis patients with cerebral infarction plaque determined by semi-quantitative method were grouped into Ⅰ grade(29 cases),Ⅱ grade (43 cases),Ⅲ grade (14 cases) according to the severity atherosclerosis.Serum levels of IL-17 and IL-23 were measured.Results The levels of IL-17 and IL-23 in patients with carotid atherosclerosis group were (31.42 ± 8.73) μg/L and(21.79 ± 9.34) μg/L,higher than that of non-carotid atherosclerosis group((22.81 ±6.52) μg/L,t =5.15,P ＜0.01 ; (14.33 ±6.21) μg/L,t =4.99,P ＜0.01).The IL-17 and IL-23 levels in patients with soft plaque,hard plaque and mixed plaque group were significant different (F =10.181,3.835,P ＜0.05).Serum IL-17 in soft plaque and mixed plaque expression group was higher than that of hard plaque group (P =0.001,P=0.007).IL-23 level in soft plaque group was higher than mixed plaque and hard plaque groups(P =0.017;P =0.045).The IL-17 and IL-23 levels in Ⅰ,Ⅱ,Ⅲ level group were markedly different (F =41.046,3.739 ; P ＜ 0.05),and there was significant difference between Ⅱ,Ⅲ and Ⅰ group(P ＜0.01,P ＜0.05).The correlation between IL-17 and IL-23 levels in Ⅰ,Ⅱ,Ⅲ level group were 0.892 and 0.420 (P =0.000 ; P =0.041).Conclusion IL-17 and IL-23 play important roles in the pathologic progress of artery sclerosis and are helpful for early diagnosis of the disease.
ABSTRACT
Objective To investigate the imbalance of T helper 17 (Th17) / CD4 + CD25 + regulatory cell (Treg) in HAM/TSP patients.Methods Enzyme linked immunosorbent assay (ELISA) was performed to measure the levels of interleukin (IL-17) and IL-10 in CSF,and flow cytometry to determine the percentage of Th17 and Treg cells in peripheral blood of patients with HAM/TSP.Results There was a significant increase in the level of IL-17 [(4.58 ± 0.70)pg/ml vs (0.76 ± 0.17)pg/ml,P ＜ 0.01] in CSF and the percentage of Th17 cells [(2.00 ± 0.64) ％ vs (0.41 ± 0.24) ％,P ＜ 0.01],but a decrease in the level of IL-10 in CSF and the percentage of Treg cells in peripheral blood of patients with HAM/TSP compared with the control group.The ratio of Th17/Treg cell (0.55 ±0.10 vs 0.06 ±0.03) in the peripheral blood of patients with HAM/TSP increased significantly compared with control group (t =12.11,P ＜0.01).Conclusions The imbalance between Thl7 and Treg cells may play an important role in the pathogenesis of the disease.
ABSTRACT
Objective To study the effect of 2-methoxyestradiol (2-ME) on proliferation,apoptosis and its mechanism.Methods K562 cells were treated with 2-ME of different concentrations and time in vitro.Cell apoptosis rate was measured by flow cytometry(FCM).Activity of NF-Kappa B in nucleus was detected by electrophoretic molility shift assay(EMSA).Results After treatment with 2-ME,K562 cells apoptotic rate increased significantly.After treatment with 4μmol/L 2-ME for 24h、36h、48h,the activity of Caspase-3 and Caspase-9 were significantly higher and activity of NF-Kappa B in nucleus was significantly lower.Conclusion The present study showed that 2-ME induced apoptosis of K562 cells via active Caspase-3 and Caspase-9 and inhibit the activity of NF-kappa B in nucleus.This study provided useful experimental data for clinical application of 2-ME.
