摘要

目的:探讨不同针灸疗法对老年大鼠血清性激素水平的影响及延缓衰老作用的基因调控途径。方法:SD老年大鼠随机分为老年组、温针灸组、温和灸组、电针组、药物组

每组8只

另取SD青年大鼠8只作为青年组。温针灸组、温和灸组及电针组取"肾俞""关元"穴治疗

每日1次

每次15min;药物组给予腹部皮下注射丙酸睾酮注射液(7mg·kg

(-1)

·3d(-1)·3d

(-1)

)。各组均治疗8周。ELISA法检测大鼠血清睾酮(T)、促性腺激素释放激素(GnRH)含量

实时荧光定量PCR法检测大鼠下丘脑中KISS-1、G蛋白耦联受体(GPR)54、RF酰胺相关肽-3(RFRP-3)、GPR147和睾丸中GnRH-R、GPR54、GPR147mRNA的表达。结果:老年组大鼠血清T、GnRH含量

下丘脑中KISS-1、GPR54、RFRP-3、GPR147mRNA表达及睾丸组织中GnRH-R、GPR54mRNA表达低于青年组(P

0.05)

睾丸组织GPR147mRNA表达量高于青年组(P

0.05)。与老年组比较

温针灸组、温和灸组、电针组、药物组血清T含量升高(P

0.05)

温针灸组、温和灸组、电针组血清GnRH含量

下丘脑KISS-1、GPR54、RFRP-3、GPR147 mRNA表达升高(P

0.05)

睾丸组织GnRH-R、GPR54mRNA表达量升高

GPR147mRNA表达量降低(P

0.05)。温针灸组、温和灸组、电针组各指标改善均优于药物组(除血清T含量外

0.05)。结论:温针灸、温和灸和电针均能显著提高老年大鼠血清T水平

温针灸、温和灸、电针与丙酸睾酮补充疗法对于血清T水平的提高程度接近

但药物并不能明显激活GnRH合成分泌通路

故温针灸、温和灸和电针更适合在临床中作为长期治疗的方法。

Abstract

Objective To observe the effect of warm needle moxibustion(WNM)

mild moxibustion and electroacupuncture(EA)of"Shenshu"(BL23)and"Guanyuan"(CV4)on serum gonadal hormone levels and related gene expression in the hypothalamus and testis in aged rats

so as to explore their underlying mechanisms in anti-aging.Methods Forty male SD male rats were randomly divided into aged control

WNM

mild moxibustion

EA and medication groups(n = 8 in each group)

and other 8 male young adult SD rats were used as the youth control group.WNM(acupuncture plus moxibustion)

mild moxibustion or EA(2 Hz/100 Hz

1 mA)was separately applied to CV4 and bilateral BL23 for 15 min

once daily

5 days a week for 8 weeks.Rats of the medication group received subcutaneous injection of testosterone propionate injection(7 mg/kg)

once every 3 days

and those of the aged and youth groups received the same dose of 0.9% NaCl solution for 8 weeks.The levels of serum testosterone(T)and gonadotropin-releasing hormone(GnRH)were measured by ELISA.The expression of Kisspeptin(KISS-1)

G protein-coupled receptors 54(GPR54)

RFamide-related peptide-3(RFRP-3)and GPR147 mRNAs in the hypothalamus and GnRH-R

GPR54 and GPR147 mRNAs in the testis tissues were detected by quantitative real-time PCR.Results The levels of serum T and GnRH

and the expressions of KISS-1

GPR54

RFRP-3 and GPR147 mRNAs in the hypothalamus and GnRH-R and GPR54 mRNAs in the testis in the aged rats were significantly lower than those in the youth rats(P<0.05)

while the expression level of GPR147 mRNA of the testis tissue was obviously higher in the aged group than that in the youth group(P<0.05).Following the treatment

the lowered serum T and GnRH contents

the down-regulated expression levels of hypothalamic KISS-1

GPR54

RFRP-3 and GPR147 mRNAs and testicle GnRH-R and GPR54 mRNAs

as well as the up-regulated testicle GPR147 mRNA expression in the aged rats were reversed in the WNM

mild moxibustion and EA groups(not the medication group except serum T)in comparison with the aged control group(P<0.05).The therapeutic effects of WNM

mild moxibustion and EA were significantly superior to those of medication in up-regulating serum GnRH content and expression levels of KISS-1

GPR54

RFRP-3 and GPR147 mRNAs in the hypothalamus and GnRH-R

GPR54 and GPR147 mRNAs in the testis(P<0.05).No significant differences were found among the WNM

mild moxibustion and EA groups in serum T and GnRH contents

and the expression levels of KISS-1

GPR54

RFRP-3 and GPR147 mRNAs in the hypothalamus and GnRH-R and GPR54 and GPR147 mRNAs in the testis(P>0.05).Conclusion The WNM

mild moxibustion and EA therapies have an anti-aging effect by increasing serum T and GnRH levels in aged rats

which is possibly related to their effects in up-regulating the expression of hypothalamic KISS-1

GPR54

RFRP-3 and GPR147 mRNAs and testicle GnRH-R and GPR54 mRNAs

as well as down-regulating testicle GPR147 mRNA expression.The therapeutic effect of WNM

mild moxibustion and EA is evidently superior to that of medication.
