RESUMEN
Objective To explore the relationship between cerebral hemorrhage and the occurrence of depression after craniocerebral injury surgery.Methods From March 2015 to March 2017,70 patients with craniocerebral injury in our hospital were selected as the subjects of study.They were divided into the observation group (n =30) and the control group (n =40) according to whether there was cerebral hemorrhage after operation.The National Institutes of Health Stroke Scale score (NIHSS),Hamilton Depression Scale score (HAMD),Glasgow Coma Score (GCS) and the levels of interleukin (IL)-1,IL-6 and high sensitivity C-reactive protein (hs-CRP) in patients with different degrees of cerebral hemorrhage were compared.The correlation between HAMD score and other indexes was analyzed.The influencing factors and independent risk factors of depression were analyzed.Results The levels of NIHSS,HAMD score and serum IL-1,IL-6 and hs-CRP in the observation group were higher than those in the control group after operation (t =13.655,36.587,45.274,46.334,70.489,P ＜ 0.05),while the GCS score was lower than that in the control group (t =15.517,P ＜ 0.05).Compared with mild and moderate cerebral hemorrhage,the NIHSS,HAMD scores and serum IL-1,IL-6 and hs-CRP were higher in patients with severe cerebral hemorrhage (F =8.825,10.254,23.615,18.745,7.245,P ＜ 0.05),while the GCS score was lower (F =7.459,P ＜ 0.05).The correlation analysis showed that the postoperative HAMD score was positively correlated with NIHSS score and serum IL-1,IL-6 and hs-CRP (r =0.289,0.364,0.333,0.258,P ＜ 0.05)and negatively correlated with the GCS score (r =-0.276,P ＜ 0.05).Univariate analysis showed that the level of culture,personality,cerebral hemorrhage degree and serum IL-6 and hs-CRP were the influencing factors of postoperative depression in patients with craniocerebral injury (t orx2 =6.076,6.300,8.361,30.224,99.575,P ＜ 0.05).Multivariate analysis showed that cerebral hemorrhage and hs-CRP were an independent risk factor for postoperative depression (P ＜ 0.05).Conclusions Cerebral hemorrhage after craniocerebral injury is closely related to the occurrence of depression,which may be related to the increase of stress-induced inflammatory factors after cerebral hemorrhage.
RESUMEN
Aim To explore the anti-angiogenic effect of tetramethylpyrazine(TMP) in the synovium of collagen-induced arthritis(CIA) in rats.Methods CIA rats were treated with different doses of TMP.The effects of treatment were monitored by arthritis index,footpad thickness,microvessels density as well as the expression of vascular endothelial growth factor(VEGF) protein and mRNA in the synovium.Results Compared with CIA models,100 mg?kg~(-1)?d~(-1) TMP remarkably reduce the arthritis index,footpad thickness,microvessels density,and the expression of VEGF protein and mRNA in the synovium (P
RESUMEN
Aim To study the effect of tetramethylpyrazine(TMP) on binding of 125I-VEGF to VEGF receptor. Methods The mice sera were collected after peritoneal injection with big-dose TMP,low-dose TMP,protamine and NS. A reversed-phase high performance liquid chromatography(RP-HPLC) method was used to determine the TMP in mice serum. The culture medium of ECV304 was treated with the mice sera in different groups. Radioligand binding assay(RBA) of receptor and Scatchard pot were performed to observe the changes of the maximum binding capacity(B_ max) and dissociation constant(K_d).Results The sera of big-dose TMP inhibited 125I-VEGF binding to its receptor, K_d=343.30?36.64 pmol?L-1,B_ max=46.26?5.85 fmol/2?10~5 cells(P0.05),but B_ max decreased(P
