Abstract:
Objective To observe the effect of Xuebijing on immunosuppressed sepsis of model mice. Methods The
152 mice were randomly divided into control group (Control), immunosuppression group (IM), immunosuppressed sepsis
model group (ISM) and Xuebijing treatment group (XT). There were thirty – eight mice for each group. For group IM,
cyclosporine A was injected intraperitoneally along the median line of the lower abdomen for immunosuppression, 25 mg/kg，
1 time every other day for a total of 3 times. For group ISM, after immunosuppression, 300 μL escherichia coli 44102 with
a concentration of 1×109 CFU/mL was injected intraperitoneally along the midline of the lower abdomen. The 30 minutes
after the establishment of the immunosuppressive sepsis model, Xuebijing 4 mL/kg was intraperitoneally injected along the
midline of the lower abdomen in the ISM group. After 30 minutes, the same dose of Xuebijing injection was repeated once.
Control group was injected intraperitoneally with the same amount of normal saline. (1) After 8 h, 4 mice in each group were
taken for blood bacterial culture. (2) After 12 h, 10 mice in each group were taken for detecting CD3+CD4+ and CD3+CD8+ in
peripheral blood using flow cytometry. (3) After 12 h, 10 mice in each group were taken for detecting blood levels of tumor
necrosis factor-α (TNF-α) and interleukin-6 (IL-6) by enzyme-linked immunosorbent assay (ELISA). (4) After 12 h, 4 mice
in each group were taken for detecting high-mobility group protein (HMGB1) by Western blot assay. (5) After 12 h, 10 mice in each group were taken for detecting alanine aminotransferase (ALT), aspartate aminotransferase (AST), urea nitrogen
(BUN) and serum creatinine (CR) levels by automatic biochemical analyzer. Results Compared with the ISM group, the
ratio of CD3+CD4+/CD3+CD8+ was significantly increased, the number of blood bacteria culture decreased obviously in the
XT group. Liver and kidney function indicators ALT, AST, CR, BUN and inflammatory factor indicators TNF-α, IL-6 and
HMGB1 were also significantly decreased in the XT group. Conclusion Xuebijing can obviously modulate the
immunosuppression, against bacteria, inhibit the inflammatory reaction, and protect the vital organs.
