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 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.

[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.

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.

GCC/PKG/VASP,PKA/VASP et.al are associated with the occurrence and development of colorectal cancer.As one of the important signaling molecules of above signal pathways,VASP has constributed to the invasion,metastasis,apoptosis,angiogenesis and other events of colorectal cancer.The role of VASP signaling pathways in the development of CRC and its potential clinlic significance are reviewed in this article.

Objective To research the mechanism or pathway through which Substance P(SP) inhibits r-aminobutyric acid(GABA) activated currents in bullfrog dorsal root ganglion(DRG) neurons.Method The experiment was conducted on freshly isolated bullfrog dorsal root ganglion neurons using a whole-cell patch-clamp technique.Results SP could caused a slow inward current when SP was applied to DRG neurons;SP could inhibits GABA-activated currents;The inhibition could be reduced largely when protein kinase C(PKC) inhibiter,1-(5-isoquinolinesulphorry)-2-methylpiperazine(H-7), was dialyzed in cell body.Conclusion The SP ton inhibit GABA-activated currents through protein kinase C.

Objective To compare the clinical effects of treating cervical prolapse of intervertebral disc by using Solis cage, titanium cage and autogenous iliac crest graft (AICG) combined with titanium plate. Methods 64 cases of cervical prolapse of intervertebral disc were analyzed retrospectively. All the patients were followed up for about one year. Group A is composed of 20 patients (30 intervertebral spaces) treated with microdiscectomy and Solis cage fusion;group B is composed of 21 patients(22 intervertebral spaces) treated with titanium cage and group C is involved of 23patients(28 intervertebral spaces) which were dealt with AICG combined with titanium plate. The differences in the to-tal X ray exposure time, time working on iliac bone, incidence of complications, fusion rate, incidence of JOA score recovery rate more than 50 % and rehabilitation time of the three groups are analyzed. Results All indexes from group A and B were more satisfactory than those from group C (P＜0. 05). The statistic analysis results of the incidence of complications of cervical part, rehabilitation time in group A are 5.0± 1.8, 5.1 ± 1.2; and that is 14.3±2.6, 7.5 ± 1.6and 26.1±6.2, 8.6±2.3 in group B and group C respectively. There is significant difference between group A and group B on the incidence of complications of cervical part and rehabilitation time (P＜0.05). Results of the incidence of JOA score recovery rate ＞ 50 % in group A(95.8 ± 3.2) was more satisfactory than that in group B(93.6 ± 2.9),while there was no statistical difference between group A and group B (P＞0.05). Conclusion The Solis cage is better in treating the cervical prolapse of intervertebral disc than other ways. Also, it makes the operation easier, rehabilitation time shorter, and it causes fewer complications.
