ABSTRACT
Objectives To investigate the effects of nerve nutrient factors and inhibitory factors on neuronal regen? eration and axonal reconstruction at ischemic neocortical penumbra after focal cerebral ischemia in rats. Methods The rat model of middle cerebral artery ischemia was established using suture-occluded method. The pathological morpholo? gy of brain tissue was examined by using HE staining. The expression levels of GAP-43 SYN, nutrient factor (BDNF VEGF Ang1) and inhibitory factor (NogoA NogoR RhoA) were determined by using Western blotting technique. Results The number of neurons in ischemic penumbra was significantly decreased in model group (P<0.01) than in sham-operat? ed group. The expression levels of GAP-43 were significantly decreased (P<0.05) while the expression levels of NogoA NgR and RhoA in the thalamus were significantly increased (P<0.05) in model group than in sham-operated group. The expression levels of SYN and nutrient factors (BDNF VEGF Ang1) were not different between the model group and sham-operated group. Conclusion The increase in nerve inhibitory factors may contribute to the down-regulation of neu?rogenesis at ischemic neocortical penumbra after focal cerebral ischemia in rats.
ABSTRACT
Objective:To discuss the changes of peripheral blood T Lymphocyte subsets in patients with chronic HBV infection to know the relation between T Lymphocyte subsets and HBV replication and the relationship between T Lymphocyte subsets and activity of liver cirrhosis.Methods:Peripheral blood lymphocytes were analysed by flow cytometry in 99 patients with chronic HBV infection.Results:The T Lymphocyte subsets counts were marked higher in patients with chronic active hepaitis B than those in patients with liver cirrhosis.CD4+/CD8+ ratios were significantly higher in active cirrhosis than those in non-active cirrhosis(P
ABSTRACT
Summarizing the literature of syndrome differentiation and treatment of alcoholic liver disease (ALD) with Traditional Chinese Medicine (TCM) in recent five years,to investigate the realization and the laws of prescribing in this disease from the perspective of selecting drugs and forming formulas of TCM. This article summarized the characteristics of formula selection in treating ALD,and summed up the treatment principle of ALD and the realization of main syndrome by the principle of 'learning syndrome from formula','correspondence of syndrome with for mula'. The results showed that promoting blood circulation for removing blood stasis,tonifying consumption,promoting diuresis and percolating dampness were the main principle of prevention and treatment of ALD in recent years,and blood stasis,qi asthenia and phlegmatic hygrosis were the major pathogenesis of ALD. According to studying the literature of TCM,it was can be seen that the present treatment of ALD was still in the exploratory stage of clinical observation,it lacked multi-center,randomized and control prospective study of large sample,and judgment of curative effect were disunity,and objective evaluation criteria was lacked. These questions were worth further exploration.
