OBJECTIVE:To observe the effect of electroacupuncture (EA) on anti-oxidant function of Leydig cells in aged rats with low testosterone, so as to reveal its underlying mechanism of anti-aging of male reproduction. METHODS:Eighteen 20 months old SD rats were divided into aged control, medication and EA groups(n=6 in each group), and other 6 young male SD rats (2 months of age) were used as the youth control group. The rats of the youth and the aged control groups received subcutaneous injection of 0.9% normal saline (7 mg·kg-1·3 d-1) for 8 weeks, and those of the medication group received abdominal subcutaneous injection of Testosterone Propionate (7 mg·kg-1·3 d-1) for 8 weeks. EA (2 Hz/100 Hz, 1 mA) was applied to bilateral "Shenshu" (BL23) and "Guanyuan" (CV4) for 15 min, once daily for 8 weeks except the weekends. The levels of serum total testosterone (TT) and free testosterone (FT) were determined by enzyme linked immune sorbent assay (ELISA), the immunoactivity of phosphorylated extracellular signal-regulated protein kinase (p-ERK) was detected by immunohistochemistry, and the expression levels of ERK, p-ERK, nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) proteins in the testis tissues were determined by Western blot. RESULTS:Before and after the treatment, the levels of serum TT and FT in the aged control group were significantly lower than those of the youth control group (P<0.01). After the treatment, the serum TT and FT contents in the EA and medication groups were obviously higher than those in the aged control group (P<0.01). Compared with the youth control group, the expression levels of ERK, p-ERK, Nrf2 and HO-1 proteins were significantly down-regulated in the aged control group (P<0.01), while in comparison with the aged control group, the expression levels of ERK, p-ERK, Nrf2 and HO-1 proteins were significantly up-regulated in the medication and EA groups (P<0.01). The therapeutic effect of EA was notably superior to that of medication in up-regulating the immunoactivity of p-ERK, and the expression levels of ERK, p-ERK, Nrf2 and HO-1 proteins (P<0.01). No significant differences were found between the EA and medication groups in the increased levels of serum TT and FT after the intervention (P>0.05). CONCLUSION:EA intervention may increase testosterone level of the aged rats, which may be related to its effects in triggering ERK /Nrf2 /HO-1 signaling (anti-oxidative stress signal pathway) in the testis.
OBJECTIVE:To observe the effect of electroacupuncture (EA) on the expression of apolipoprotein E (ApoE) and related proteins of inflammation and anti-oxidative stress in spinal cord in mice with spinal cord injury (SCI), so as to explore its mechanisms underlying function repair. METHODS:Thirty-six female C57BL/6 mice were equally randomized into 3 groups: sham operation, model and EA. The SCI model was established by clamping the spinal cord for 25 s with a serrefine after laminectomy of the 1st lumbar vertebra (L1). EA (1.5 Hz/7.5 Hz, 1.0 mA) was applied to bila-teral "Zusanli" (ST36) and "Sanyinjiao" (SP6) for 10 min, once a day for 7 days. The hindlimb locomotor function was assessed according to the state of the range of motion, coordination, claw gesture of the hind leg ankle-joint, trunk stabi-lity and the tail posture by using Basso Mouse Scale(BMS). The histopathological changes of the injured area of the spinal cord were determined by H.E. staining. The expression levels of ApoE, phosphorylated nuclear transcription factor-κB(p-NF-κB), interleukin 1 beta(IL-1β), phosphorylated extracellular regulatory protein kinase(p-ERK1/2), extracellular regulatory protein kinase(ERK1/2), nuclear factor erythroid 2-related factor 2(Nrf2) and heme oxidase-1(HO-1) in the spinal cord were detected by Western blot, and the glial fibrillary acidic protein (GFAP)-positive astrocytes were displayed by immunofluorescence staining. RESULTS:After modeling, the BMS scores were significantly decreased in the model group compared with the sham operation group (P<0.05). Following EA, the BMS scores were markedly increased in the EA group relevant to the model group (P<0.05), suggesting an improvement of the hindlimb locomotor function. H.E. stain showed structural disorder with lots of cavities, severe inflammatory infiltration with large quantity of inflammatory cells, and apparent reduction of normal neurons in the injured spinal cord tissue of model group, which was milder in the EA group. The expression levels of ApoE, p-NF-κB, IL-1β, p-ERK1/2 (not ERK1/2), Nrf2 and HO-1 were significantly increased in the model group than those in the sham operation group (P<0.05). Compared with the model group, the expression levels of ApoE, p-ERK1/2, Nrf2 and HO-1 were further notably up-regulated (P<0.05), and those of p-NF-κB and IL-1β proteins obviously down-regulated in the EA group (P<0.05). Immunoflorescence staining showed that the number of GFAP-positive cells was apparently increased in the model group compared with the sham operation group and observably decreased in the EA group relevant to the model group (P<0.05). CONCLUSION:EA can significantly improve locomotor function in SCI mice, which is associated with its effects in reducing inflammation, oxi-dative stress reactions and reactive astrocyte proliferation via up-regulating expression of ApoE, p-ERK1/2, and Nrf2/HO-1 (antioxidant pathway) and inhibiting IL-1β and NF-κB expression.
