The nature and functions of astrocytes (AS)， the pathological changes and roles of AS after spinal cord injury， the experimental methods of inhibiting AS proliferation and glial scar formation， and so on, were reviewed. AS beneficially affects repairing injured spinal cord at different periods of differentiation. However， adult AS secreting the factors formed the chemical glial barrier which severely affects nerve regeneration and hinders axon extension. Because of the static， activated and proliferative AS tending to coexist after spinal cord injury， and complex factors of barrier formation， the current approach taken by a single method is difficult to effectively control the AS proliferation and glial scar formation.

0.05).The grade of antibiotics tended to decline with the increase in of dressing change freqnency so it could decrease the expenditure of antibiotics.The rate of fungal infection lowered while hospitalization did not appear to be prolonged.CONCLUSIONS After the analysis of the use of antibacterials for burn patients,we find that the proper use of antibiotics and the increase in dressing change would lower the grade of antibiotics and expenditure,at the same time they do not increase the rate of bacterial infection and fungal infection,and do not prolong the duration of patients hospitalization time.

Objective To investigate the effects of low-dose of hydrocortisone on circulating thymus-dependent lymphocyte (T lymphocyte) apoptosis in patients with septic shock. Method fifty-seven patients with septic shock admitted into ICU from January 2006 to January 2009 were prospectively randomized (random number) to treatment group and control group. Another 20 healthy volunteers and 18 patients with sepsis alone were included as external control groups.The patients of treatment group and control group were treated with low-dose of hydrocortisone and placebo,respectively. Samples of peripheral blood were taken from healthy volunteers and patients 0 hr,24 hrs,48 hrs,72 hrs and 168 hrs after onset of the disease to determine the circulating T lymphocyte apoptosis by using the assays of Annexin V and flow cytometry. Least significant difference t -test was used for multiple comparisons. Results The percentage of Annexin V-positive CD4+ T lymphocytes in the primary stage was (11.01 +4.52)% in septic shock patients, (4.41 + 1.45)% in healthy volunteers, and (7.87 + 3. 82)% in patients with sepsis alone. And in the initial setting, the percentage of Annexin V-positive CD4+ T lymphocytes in the septic shock patients was higher than that in healthy volunteers ( P < 0.05) and in patients with sepsis alone ( P < 0.05). The percentage of Annexin V-positive CD8 + T lymphocytes at the beginning was (11.33+19.62)% in septic shock patients, (9.62+8.32)% in healthy volunteers, and (13.09+ 15.84)% in patients with sepsis alone (P > 0.05 between three groups). The percentages of Annexin V-positive CD4+ T lymphocytes in control group after 24 his, 48 hrs and 72 hrs were(13.51+6.85)%, (19.39 + 6.63)% and (15.33+ 6.21)%, respectively. And the percentages of Annexin V-positive CD4+ T lymphocytes in treatment patients after 24 hrs, 48 hrs and 72 hrs were (17.4 + 7.21)%, (22.61 + 5.64)%, and (25.73 + 6.91)%, respectively. The percentage of Annexin V-positive CD4+ T lymphocytes in septic shock patients was higher than that in control groups ( P < 0.05). The percentages of Annexin V-positive CD8+ T lymphocytes in control group after 24 hrs, 48 hrs and 72 hrs were (11.49+ 11.73)%, (12.74+ 10.39)% and (13.28+ 16.6)%, respectively, and in the treatment group, those were (9.49 + 8.9)%, (15.32+18.17)% and (13.68+16.84)%, respectively (P >0.05 between two groups). In the meantime, the percentages of Annexin V-positive CDS'1' T lymphocytes in control group and in treatment group were (12.72+ 19.69)% and (13.88 + 13.28)%, respectively (P >0.05). Conclusions Low-dose of hydrocortisone could induce CD4+ T lymphocyte apoptosis and has no effects on CD8+ T lymphocyte apoptosis when it is used to treat septic shock.

AIM: To explore the effect of Bu Shen Yang Xue Ming Mu (BSYXMM) Formula on hydroquinone-induced oxidative stress injury in ARPE-19 cells.METHODS: The oxidative injury model of ARPE-19 cell was induced by exposure to various concentrations of hydroquinone (HQ) to determine the optimal concentration.Intestinal absorption solutions of BSYXMM Formula were prepared.Effect of intestinal absorption solutions of BSYXMM Formula on the cell viability was detected by CCK-8 assay,and the percentage of apoptotic cells was measured by TUNEL assay.The levels of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) in ARPE-19 cells were detected by means of chemical colorimetry.RESULTS: It was found that ARPE-19 cell viability significantly decreased when the concentration of HQ was higher than 90μmol/L.Compared with the model group,1% and 2% intestinal absorption solutions in the pre-treatment group could significantly alleviate HQ-induced injury (P<0.01) and 0.5% and 5% intestinal absorption solutions in the pre-treatment group could alleviate the injury in certain degree(P<0.05).While in the treatment group 1% and 2% intestinal absorption solutions could alleviate the injury to some extent (P<0.05).TUNEL results showed that the apoptosis rate decreased significantly in the pre-treatment group (P<0.01)and to some extent in the treatment group (P<0.05)compared with the model group.It was shown that both levels of SOD and GSH-Px in pre-treatment group and treatment group were markedly higher than that of model group(P<0.05),and pre-treatment group had more significant effect (P<0.01,P<0.05).CONCLUSION: BSYXMM Formula could protect against HQ-induced oxidative stress injury in ARPE-19 cells,which may be related with the increasing of antioxidant enzyme in the cells.
