OBJECTIVE:
To assess the impacts of electroacupuncture (EA) on the gait, oxidative stress, inflammatory reaction, and protein degradation in the rats of denervated skeletal muscle atrophy, and explore the potential mechanism of EA for alleviating denervated skeletal muscle atrophy.
METHODS:
Forty male SD rats, 8 weeks old, were randomly assigned to a sham-surgery group, a model group, an EA group, and a p38 MAPK inhibitor group, with 10 rats in each group. The right sciatic nerve was transected to establish a rat model of denervated skeletal muscle atrophy in the model group, the EA group and the p38 MAPK inhibitor group. In the sham-surgery group, the nerve was exposed without transection. One day after successful modeling, the rats in the EA group received EA at "Huantiao" (GB30) and "Zusanli" (ST36) on the right side, using a continuous wave with a frequency of 2 Hz and current intensity of 1 mA, for 15 min in each session, EA was delivered once a day, 6 times a week. In the p38 MAPK inhibitor group, the rats received the intraperitoneal injection with SB203580 (5 mg/kg), once a day, 6 times a week. The intervention was composed of 3 weeks in each group. After the intervention completion, the CatWalk XT 10.6 animal gait analysis system was used to record the gait parameters of rats. The wet weight ratio of the gastrocnemius muscle was calculated after the sample collected. Using HE staining, the fiber morphology and cross-sectional area of the gastrocnemius muscle were observed; ELISA was employed to measure the content of interleukin (IL)-6, IL-1β, and tumor necrosis factor (TNF)-α in the gastrocnemius muscle; the biochemical hydroxyamine method was adopted to detect the content of superoxide dismutase (SOD) and malondialdehyde (MDA) in the gastrocnemius muscle; with immunohistochemistry and Western blot used, the expression of p38 mitogen-activated protein kinase (p38 MAPK), phosphorylated (p)-p38 MAPK, muscle atrophy F-box gene (Atrogin-1), muscle RING finger 1 (Murf-1), nuclear factor E2-related factor 2 (Nrf2), and heme oxygenase-1 (HO-1) was detected in the gastrocnemius muscle.
RESULTS:
Compared to the sham-surgery group, in the model group, the standing duration, the swing time and the step cycle were increased (P<0.001), the footprint area of the maximum contact time, the print area, the average intensity of the maximum contact time, the average intensity, the swing speed, and the step length were decreased (P<0.001); the wet weight ratio of gastrocnemius muscle and fiber cross-sectional area were reduced (P<0.001); the content of IL-6, IL-1β, TNF-α and MDA in gastrocnemius muscle elevated (P<0.001), and that of SOD reduced (P<0.001); the positive and protein expression of p-p38 MAPK, Atrogin-1 and Murf-1 elevated (P<0.001) and that of Nrf2 and HO-1 dropped (P<0.001). When compared with the model group, in the EA group and the p38 MAPK inhibitor group, the standing duration, the swing time and the step cycle decreased (P<0.01), the footprint area of the maximum contact time, the print area, the average intensity of the maximum contact time, the average intensity, the swing speed, and the step length increased (P<0.01); the wet weight ratio of gastrocnemius muscle and fiber cross-sectional area were improved (P<0.01, P<0.05); the content of IL-6, IL-1β, TNF-α and MDA in gastrocnemius muscle dropped (P<0.05, P<0.01), and that of SOD elevated (P<0.01, P<0.05); the positive and protein expression of p-p38 MAPK, Atrogin-1 and Murf-1 dropped (P<0.01, P<0.05) and that of Nrf2 and HO-1 increased (P<0.01, P<0.05).
CONCLUSION
Electroacupuncture may alleviate skeletal muscle atrophy in denervated skeletal muscle atrophy rats by mediating the p38 MAPK activity, thereby suppressing oxidative stress, inflammatory reaction, and protein degradation.

Snake bites are characterized by acute onset,rapid changes in condition,and high disability and mortality rates.The effects of snake venom on the human body are divided into systemic and local toxic effects.The popu-larity of antivenom has greatly reduced the mortality of snake bites,but local tissue damage and permanent dysfunction are still problems to be solved urgently.Studies have found that snake venom metalloproteinases,hyaluronidases,phospholi-pases and other venoms participate in a variety of local pathological effects by interfering with the degradation and remodel-ing of extracellular matrix(ECM).This article reviews the mechanism of ECM in the development of local tissue damage caused by snake bites,in order to find effective therapeutic targets and provide reference and ideas for the clinical research and prevention of local tissue damage caused by snake bites.

Objective:To investigate the relationship between the activation level of Nod-like receptor pyrin domain-containing 3 (NLRP3) inflammasome and the change of cognitive functions in patients with acute ischemic stroke.Methods:A total of 88 patients with acute ischemic stroke in Department of Neurology from October 2018 to July 2020 were selected as case group and 100 healthy physical examinees were selected as control group.Peripheral blood of the case group and the control group was collected, and peripheral blood mononuclear cells (PBMCs) were isolated by centrifugation.Then the NLRP3, apoptosis-associated speck-like protein containing a CARD (ASC), Caspase-1 and interleukin-1β (IL-1β) expression were detected by Western blot.The cognitive function of patients with acute ischemic stroke was detected by Montreal Cognitive Assessment (MoCA). The differences in expression levels of NLRP3, ASC, Caspase-1 and IL-1β were compared between the case group and the control group.Pearson correlation analysis was used to analyze the correlation between expression levels of NLRP3, ASC, Caspase-1, IL-1β and MoCA score.Logistic multivariate regression was used to analyze the relationship between expression levels of NLRP3, ASC, caspase-1, IL-1β and the cognitive dysfunction.Results:(1)Western blot results showed that NLRP3, ASC, Caspase-1 and IL-1β expressions in PBMCs cells in the case group were higher than those in the control group (all P<0.05). (2)The expression level of NLRP3 in stroke patients with hypertension, hyperlipidemia, National Institutes of Health Stroke Scale (NIHSS) score ≥ 8 points was significantly higher than that in patients without hypertension, hyperlipidemia and NIHSS score<8 points ( P<0.05); (3)The incidence of cognitive dysfunction in the case group was 34.09% (30/88). The MoCA scores of the cognitive dysfunction group and the non-cognitive dysfunction group were 20 (24, 28) and 27 (26, 28) points respectively, and the difference between the groups was statistically significant ( P<0.05); (4)Pearson correlation analysis showed that NLRP3, ASC, caspase-1 and IL-1β expression in PBMCs cells were negatively correlated with MoCA scores ( r=-0.426, -0.396, -0.417, -0.320 respectively, all P<0.05). (5)Logistic regression analysis showed that hyperlipidemia, NIHSS scores, frontotemporal lobe infarction, and NLRP3 expression were the influencing factors for the occurrence of cognitive dysfunction (all P<0.05). Conclusion:Patients with acute ischemic stroke have high activated NLRP3 inflammasome, and its activation degree is closely related to the condition and the occurrence of cognitive dysfunction after stroke.Targeted inhibition or regulation of NLRP3 inflammasome activation may become a new idea of neuroprotection for acute ischemic stroke.
