Objective To observe the effect of ketamine on apoptosis and synaptophysin expression in 7-day-old infant SD rat hippocampal neural cells. Methods Thirty SD rats of 7 days old were randomly assigned to receive the injection of 25 mg/kg ketamine (K_ 1 group)or 50 mg/kg (K_ 2 group) or 50 ml/kg normal saline (K_ 0 group). In 24 h after injecton, all rats were killed and the synaptophysin was tested by using immunhistochemistry and Western blotting, the apoptosis of neuronal cell by Tunel. Results In 24 h after injection of ketamine,the number of apoptotic neural cells increased,which of K_ 0 group was (5.3?1.7), K_ 1 group (9.5?4.2), K_ 2 group (23.4?7.6), and the grey values of synaptophysin by immunhistochemistry of K_ 0 group was (174.11?4.68), K_ 1 group (181.36?4.17), K_ 2 group (198.25?3.06), and the OD values of synaptophysin piece decreased, which of K_ 0 group (4 007?758), K_ 1 group (2 621?465), K_ 2 group (987?183). Conclusion In 24 h after treatment with ketamine, the expression of synaptophysin was decreased in hippocampl neural cells, the number of apoptotic neuronal cells were increased, which may be involved in neurotoxicity caused by ketamine.

[Objective]To explore the effect of combined acupuncture and medicine on learning--memory abilities,and free radical system of hippocampus in vascular dementia(VD)rats.[Methods]The 48 Sprague Dawley rats were randomly divided into control(1),VD model(2),VD plus removed olfactory bulb model(3)and XIU Three Needles(4),Eugenol(5),combined acupuncture and medicine(6)groups.Morris maze tests were conducted for valuating the learning and memory abilities.The contents of MDA,SOD and GSH-Px activity of hippocampus were detected.[Results]In comparison with group 1,the average escape latency and travel distance prolonged significantly in group 2.In comparison with group 2,it shortened remarkably in groups 4 and 5.No significant differences were found between groups 1 and 2.In comparison with group 6,it prolonged in groups 4 and 5.No significant differences were found between them.The MDA content of hippocampus in VD model group was higher than that of control group(P

Objective To investigate the preventive effect of health education on prevention of vaginitis among Guangzhou ’ s career women.Methods 479 career women with confirmed diagnosis of vaginitis in 2013 were cured and followed up for 1 year.Pa-tient were divided into Control Group (n=202) and Observation Group (n=277) according to whether accompanied the health edu-cation on prevention of vagnnitis.The recurrence rate of vaginitis during the 1 -year follow -up was compared between the two groups.Results In Control Group, 192 patients (95.05%) finished the follow -up, and in Observation Group, 260 patients (93.86%) finished the follow-up, there was not statistical difference in accomplishment ratio of follow -up (p>0.05).The recur-rence of rate of vaginitis was statistical higher in Control Group (72/192, 37.50%) than that in Observation Group (64/260, 24.62%) (P<0.05).Conclusion Health education could reduce the recurrence rate of vaginitis significantly.

Objective:To investigate the difference in expression of FasL and ICAM-1 in the tonsillar HEV associated with IgA nephropathy (IgAN) and recurrent tonsillitis (RT).Methods:Human tonsils were obtained from the patients with RT (n=18) or IgAN (n=12).HE staining was used to show the morophometry of the tonsillar HEV.CD20+,CD3+ lymphocytes and distribution of FasL and ICAM-1 in the HEV were observed with immunohistochemical stained tissue section.The quantitatively experimental data from pathological image analysis were compared between IgAN and RT group.Results:(1)The expressing intensity of ICAM-1 was (0.435 5?0.002) in IgAN group and (0.239 5?0.010 4) in RT group,respectively (P0.05).Conclusion:A significant increase in the number of tonsillar HEV and increased lymphocytes in HEVs may indicate the abnormalities in peripheral blood in the patients with IgAN,thus leading to an overactivation of the tonsillar HEVs that induce Fas-dependent apoptosis in such patients.A stronger biological effective adhesion molecule promotes the transendothelial migration of lymphocytes across HEVs of palatine tonsil,which appears to be connected with the development of IgAN.

Skeletal muscle has high regenerative capability. It is able to regenerate completely after acute traumatic damage, while the repairing process often accompanied by fibrosis in the chronic degenerative conditions such as muscular dystrophy and repeated muscle fiber damage. Through in-depth study on the mechanisms of skeletal muscle fibrosis in the past decade, it has been found that a variety of cells and regulatory molecules involved in the process, especially muscle satellite cells-derived myofibroblasts, transforming growth factor β (TGF-β) and other fibrosis promoting growth factors. This review focused on the cellular and molecular mechanisms of the skeletal muscle fibrosis and relevant antagonistic strategies.

Aim To study the protective effects of Ganoderma lucidum polysaccharides peptide(GLPP)on the human umbilical vein endothelial cells(HUVECs)injured by reactive oxygen species(ROS),derived from tert-butylhydroperoxide(t-BOOH).Methods Vascular endothelial cells were obtained from infant umbilical cord for primary cultivation,identified by endothelial cell adhesion molecule-1(CD31)by fluorescence microscope.HUVECs were injured by ROS,derived from t-BOOH.The survival rate of cells was measured by Cell Counting Kit-8 assay.Hoechst 33258 nucleus staining was used to observe the early apoptosis injury by ROS.And the activation of Caspase-3 was detected by spectrophotometry.Electron microscopy was used to show the morphological changes in HUVECs.Results GLPP(6.125,12.5,25,50,100 mg?L-1)could inhibit the apoptosis of HUVECs by ROS.The survival rate of HUVECs was increased by GLPP and the percentage of cell apoptosis was decreased by it too.GLPP decreased the activation of Caspase-3 of HUVECs up-regulated by ROS.Electron microscope showed that the organelle such as mitochondria injury by ROS could be relieved by GLPP.Conclusion GLPP can prevent human umbilical vein endothelial cells from oxidative injury.

Objective To explore the inhibitory effect of pulsed ultrasound on skeletal muscle fibrosis after injury.Methods Thirty elderly male rats with gastrocnemius muscle injury were divided into an ultrasound group (UG) and a control group (CG) using a random number table.The injured muscles in the UG were treated using pulsed ultrasound (frequency 1 MHz,average strength 40 mW/cm2,duty cycle 20％) for 10 min daily from day 3 after the injury.The CG was given no treatment.On days 3,7,14,21 and 28 after the injury,histological and immunohistochemical analyses of the gastrocnemius muscles of both groups were performed.Results The collagen fiber mean optical density of the muscles increased gradually after the injury and reached its peak on day 21.It was significantly lower in the UG than in the CG on each test day.The expression of α-SMA increased gradually after the injury,but it too remained significantly lower in UG than that in CG.Conclusion Pulsed ultrasound may reduce collagen formation and α-SMA expression in injured skeletal muscle,and then inhibit muscle fibrosis.

ObjectiveTo investigate the therapeutic effect of narrow band ultraviolet B ( NB VUB)and its influence on the expression of IL23/Th17 axis in peripheral blood of patients with Psoriasis vulgaris,and to further explore the mechanism of action of NB UVB.MethodsForty - eight cases of Psoriasis vulgaris were treated with NB-UVB irradiation for 20 times,the therapeutic effect was evaluated by the Psoriasis Area and Severity Index (PASI) scores.Peripheral blood was obtained from normal healthy controls and patients with Psoriasis vulgaris before and after NB-UVB irradiation.Three color flow cytometry was carried out to quantify Thl7 cells,and ELISA was used to examine the levels of serum IL17 and IL23.Results The mean PASI scores were significantly decreased after treatment with NB UVB irradiation[ (8.12±4.05)score vs (3.98±2.03) score,P＜0.01 ].Levels of Th17[ (2.78 ± 1.93)％ vs (0.98±0.56)％ ],IL-17[ (23.85±7.98) pg/ml vs (6.53±4.26) pg/ml] and IL-23 [ (29.73 ± 12.08)pg/ml vs ( 16.73±8.91 )pg/ml] were significantly higher in patients with Psoriasis vulgaris than that in healthy controls ( P ＜0.01 ).After treatment with NB-UVB irradiation,levels of Th17 [ ( 1.13 ± 0.51 ) ％ ],IL-17 [ ( 8.03±5.01 )pg/ml ],and IL-23 [ ( 17.03 ± 9.85 )pg/ml ] were significantly decreased than before ( P ＜ 0.01 ),and were positively correlated with PASI ( P ＜0.05).ConclusionsNB-UVB may affect IL23/IL17 to achieve its therapeutic effect on patients with Psoriasis vulgaris.
