Objective To investigate the effects of minocycline,a selective microglia inhibitor on dorsal GABAB receptor expression in the spinal cord in a rat model of neuropathic pain and the possible mechanism.Methods Forty-eight male SD rats weighing 220-260 g were used in this study.Neuropathic pain was induced by ligation of L5 spinal nerve(SNL).The animals were randomly divided into 4 groups(n=12 each):Ⅰ sham operation;Ⅱ SNL;Ⅲ sham operation+intrathecal(IT)minocycline 50 μg;IV SNL+IT minecycline 50 μg.Paw withdrawal threshold to von Frey hair stimulation was measured before operation(baseline)and at post-surgery days 1,2,4,6,8,10,12,14,16,18 in 6 animals in each group.The GABABR2 expression in dorsal horn of spinal cord was detected by Western blot at the time point when paw withdrawal threshold to mechanical stimulation was the lowest in another six animals which did not undergo yon Frey hair stimulation test.Results The paw withdrawal threshold to mechanical stimuli and the GABABR2 expression in the dorsal horn of spinal cord were significantly lower in SNL group than in sham operation group.The decreased paw withdrawal threshold to von Frey hair stimulation and the down-regulated GABABR2 expression in the spinal cord induced by SNL were ameliorated by intrathecal administration of micmglia inhibitor- minocycline in group Ⅳ.Conclusion The mechanism of neuropathic pain mediated by microglia activation may be related to the inhibition of GABAB receptor activation.

Objective To investigate the effects of transplantatation human endothelial progenitor cells onneurological functional recovery from spinal cord injury model in rats,survival of transplanting cells and differentia-tion. Method The human endothelial progenitor cells were provided by Shanghai Developmental Biology Labora-tory.Forty SD rats were made for the animal model of spinal cord complete transection.Thirty survival SD rats wererandomly divided into three groups:sham operation gronp(group A, n = 10),operation/cell group(greup B, n =10) and operation/DMEM group (group C, n = 10).Suspension containing (hEPCs 6×106) was transplanted in-to the vertebral canal around injured spinal cord. In group C, equal volume of DMEM was injected insbead in the same way as in the group B. The BBB score was obtained 2,4,6,8 weeks after injection, Immunohistochemistry andin-situ hybridization were used to observe the cells survival and differentiation in the spinal cord. The BBB test wasperformed to study the functional improvement of cells. The SAS version. 1.3 software for statistics was to studyethology and functional improvement. The sum of ranks was checlced with Kruskal-Wallis Test and Nemenyi test.Results There were statistically significant differences in BBB scoring between group A and group B as well asgroup C after operation (P<0.05). The BBB score in group B was higher than that in group C after 2,4,6 and8 weeks,but lower than in group A. The hybridization in-situ and immunohistochemistry showed that transplantedcells survived for 8 weeks after transplantation and expressed specific characteristics for ancestral cell and differentiated into vascular endothelial cell (VEC). Conclusions After transplantation, hEPCs can survive, differenti-ate into vascular endothelial cell,and improve spinal cord function as compared with control group.

Objective:To explore the possible role and clinical significance of Th1 and Th2 class cytokines in the pathogenesis of re-current aphthous ulcer (RAU).Methods:35 cases with RAU,25 of minor RAU(MiRAU)and 1 0 of major RAU(MaRAU),were enrolled and 24 healthy subjects served as the controls.The expression levels of Th1 type cytokines (IFN-γ,TNF-α,IL-2)and Th2 type cytokines (IL-4,IL-6,IL-1 0)in the serum of peripheral blood were investigated by flow cytometry CBA methods and their rela-tionship with the clinical features of RAU was analyzed by SPSS 1 1 .5.Results:The expression level of IL-4 and IL-1 0 in MiRAU group was higher than that in the controls(P <0.05),and the expression level of IFN-γ,IL-4 and IL-1 0 in MaRAU group was higher than that in the controls(P <0.05).The expression level of IFN-γand IL-1 0 in MaRAU was higher than that in MiRAU.There was a positive correlation between the levels of IFN-γ,IL-4,IL-1 0 and the severity of RAU.Conclusion:Predominant Th2 immune re-sponse plays a role in RAU,and the level of IFN-γ,IL-4 and IL-1 0 is correlated with the severity of RAU.

Objective:To analyze the characteristics of immune status in patients with different types of oral lichen planus(OLP). Methods:197 cases of OLP,61 with reticular OLP(ROLP)and 136 with hyperaemia erosion OLP(HEOLP)were included.The im-mune status of the patients were investigated by flow cytometry (FCM)for the expression of CD3 +,CD4 +,CD8 +,CD19 +,CD16 ++56 +and CD4 +/CD8 +cells,and nephelometry for the measurements of IgG,IgA,IgM,C3 and CH50 in peripheral blood.The la-brotary norm was used as the reference and the characteristics of immune status in patients with different clinical characters of OLP were analyzed by SPSS 16.0.Results:CD3 +,CD4 +,IgA and C3 decreased,CD19 +cells,IgG,IgMand CH50 increased in patients with OLP.CD16 ++56 +,CD4 +/CD8 +cells decreased in the cases with ROLP(P<0.05);CD8 +cells decreased in the cases with HE-OLP.CD3 +,CD8 +cells were fewer in HEOLP patients than that in ROLP,CD4 +/CD8 +cells were more in HEOLP than that in ROLP(P<0.05).Conclusion:There are defects of cellular immune function and increase of humoral immune in patients with OLP. The patients with different clinical types of OLP may have different immune fuction changes.

Objective To compare the effects of equivalent dose sufentanil,remifentanil or fentanyl on hemodynamic and cardiac output in the elderly patients during induction of general anesthesia.Methods Ninety elderly patients(ASA Ⅰ ～ Ⅱ) undergoing elective abdominal surgery under general anesthesia were randomly divided into sufentanil group(group S),remifentanil group(group R) and fentanyl group(group F),30 patients in each group.Patients in group S,group R and group F received sufentanil 0.2μg/kg,remifentanil 2μg/kg and fentanyl 2μg/kg Ⅳ,respectively,using an blind method before intubation.SBP,DBP,MAP,HR,CO,CI and SVR were recorded before of anesthesia (T0),immediately after induction (T1),1,3 minutes after tracheal intubation (T2,T3).Changes of SBP and HR during observation were also recorded.Results The MAP and HR in three groups at T1 were significantly lower than those at T0 and decreased significantly in group R than those in group F and S(P ＜0.05).The MAP and HR in group F significantly increased at T1 than T0.The MAP and HR in group R were significantly decreased after tracheal intubation.Compared with the baseline,the MAP and HR in group S at T1,T2,remained unchanged.In group R,there were two patients whose HR were under 50 bpm.In group F,the MAP at T1,T2 were significantly higher than those at T.In group S,there were no significant changes in CO,CI,SVR which were all within normal range (P ＞ 0.05).Conclusion Both sufentanil and remifentanil effectively inhibit the stress response during induction of general anesthesia.At the same time,sufentanil has better hemodynamic stability.

In this cross-sectional study, consecutive Chinese Han ethnic inpatients in the Division of Cardiology, the First Affiliated Hospital of Soochow University from January 1, 2010 to December 31, 2013 were included. According to the exclusion criteria, 9 587 patients [1 604 with type 2 diabetes mellitus (T2DM) and 7 983 without T2DM]were obtained for final analysis. Logistic regression model was used to analyze the association of ApoB/A-1 ratio with T2DM and the possible interactions between ApoB/A-1 ratio and other risk factors. The results showed that the distribution of ApoB/A-1 ratio was positively skewed in Chinese Han ethic population. The median of ApoB/A-1 ratio of female was lower than that of male (0.68 vs 0.73,P<0.01). In all groups, the proportion of T2DM was increased with the raised ApoB/A-1 ratio. By the stratification analyses of sex, age, coronary artery disease, and the use of statins, ApoB/A-1 ratio was still correlated with T2DM. There existed significant interactions between ApoB/A-1 ratio and the smoking status or creatinine in T2DM.
