To investigate whether sepsis-induced neuroinflammation of medulla visceral zone (MVZ) predominates the systemic inflammation through cholinergic anti-inflammatory pathway (CAP), and to explore the effect of central anti-inflammation on systemic inflammation. 112 adult Sprague-Dawley male rats were randomly divided into sepsis experimental group (n = 56) and neuroinflammation experimental group (n = 56). The two experimental groups were individually randomly divided into control group (n = 8), model group (n = 16), central anti-inflammatory group (n = 16) and vagus transection group (n = 16). Rats in two control groups were administered with saline at the dose of 6 mL/kg intraperitoneally or with 25 μL artificial cerebrospinal fluid injected into forth ventricle once a day for 3 days. Rats in two model groups were administered with Lipopolysaccharide (LPS) at the dose of 6 mg/kg intraperitoneally or with 25 μg/25 μL LPS injected into forth ventricle once a day for 3 days. Rats in two central anti-inflammatory groups were fed with 10 mg/mL minocycline sucrose solution as the only water source for 4 days prior to be treated as the model groups of their own, and feeding style was continued until the end of the experiment. Rats in the two vagus transection groups were undergone right vagotomy and 7 days of adaptive feeding prior to be treated as the same as those in the central anti-inflammatory group of their own. The Murine Sepsis Score (MSS), mortality rate and heat rate variability (HRV) were recorded during the last 3 days of intervention. Then the rats were sacrificed and blood samples were collected for ELISA analysis to detect the serum level of inflammatory cytokines such as TNF-α, IL-6, and IL-10. The expression of TNF-α and IL-6 in medulla oblongata were analyzed by Western blot. The correlation and regression analysis among the expression levels of cytokines in medulla oblongata, HRV indexes and serum inflammatory cytokines were performed. The mortality rate and MSS of the sepsis model group and the MVZ's neuroinflammation model group were significantly higher than those of their own control group, and the central anti-inflammation reduced the mortality rate and MSS scores of the two model groups, while the right vagotomy abolished the effect of central anti-inflammatory. In the sepsis model group and the MVZ's neuroinflammation model group, the levels of TNF-α, IL-6, and other cytokines in serum and MVZ were significantly increased, and HRV indexes (SDNN, RMSSD, LF, HF, LF/HF) were significantly decreased (P = 0.000). Central anti-inflammatory treatment reversed the above changes. However, right vagotomy abolished the central anti-inflammatory effect. Correlation and regression analysis showed that there was a significant linear correlation among the expression of inflammatory factors in MVZ, the indexes of HRV and the levels of serum cytokines. Our study shows that sepsis-induced MVZ's neuroinflammation exert a powerful influence on the systemic inflammation through CAP in sepsis. Central anti-inflammation effectively improves systemic inflammation through inhibiting MVZ's neuroinflammation in sepsis. The time domain and frequency domain indexes of HRV can reflect the regulatory effect of CAP and the degree of inflammation of MVZ, which may be potentially used to monitor the condition and treatment effectiveness of sepsis patients.
