目的
2
探究砭贴预处理内关、太渊、人迎穴对急性低压低氧模型大鼠心肌损伤和氧化应激程度的影响。
方法
2
将36只SD雄性大鼠,随机分为空白组、模型组、砭贴组、药物组,每组9只。空白组和模型组不进行干预,砭贴组大鼠每日在双侧内关、太渊、人迎穴处贴砭贴2 h,药物组大鼠按照280 mg/(kg·d)剂量进行大株红景天胶囊灌胃。干预14 d后,除空白组大鼠外,其余3组大鼠均需放入氧舱中持续24 h以模拟高原6000 m海拔环境。出舱后进行腹主动脉取血、心肌组织取材。用ELISA法测定大鼠血清和心肌中肌酸激酶同工酶(creatine kinase isoenzymes
CK-MB)、肌钙蛋白I(cardiac troponin I
cTnI)、脑钠肽(B-type natriuretic peptide
BNP)表达,测定心肌组织丙二醇(malondialdehyde

Objective
2
To observe the effects of preconditioning with bian-stone patches at acupoints Neiguan (PC 6)
Taiyuan (LU 9)
and Renying (ST 9) on myocardial injury and oxidative stress in rats with acute hypobaric hypoxia.
Methods
2
36 male SD rats were randomly divided into the blank group
model group
patch group and drug group
with 9 rats in each. The blank group and model group were not given any interventions. Bian-stone patches were applied on the rats in the patch group at Taiyuan
Neiguan
and Renying points on both sides of the body and kept in place for 2 hours every day. Rats in the drug group were given 280 mg/kg of Rhodiola Capsule daily. After 14 days of intervention
all groups except the blank group entered the oxygen chamber which simulated the plateau environment at an altitude of 6000 m and stayed there for 24 hours. After they left the chamber
blood samples from the abdominal aorta and myocardial tissues were collected from the rats. The expressions of creatine kinase-MB (CK-MB)
cardiac troponin I (cTnI) and brain natriuretic peptide (BNP) in the serum and myocardium
and also the expressions of malondialdehyde (MDA)
hydrogen peroxide (H
2
O
2
) and hypoxia-inducible factor-1α (HIF-1α) in the myocardial tissues were determined by ELISA. The pathological changes of the myocardial tissues were observed and their water content were measured by HE staining.
Results
2
Pathological sections showed that the myocardial tissue cells in the model group were dissolved
broken and intercellular space widened. The pathological changes in the patch and drug groups were milder than those in the model group
and the hypoxic injury was not significant. Compared with the blank group
the myocardial water content in the model group was increased (
P
<
0.05)
the serum levels of CK-MB
cTnI and BNP were elevated (
P
<
0.05)
and the myocardial levels of CK-MB
cTnI
BNP
H
2
O
2
MDA and HIF-1α were raised (
P
<

P
<
0.05). Compared with model group
the myocardial water content in the patch group was increased (
P
<
0.05)
serum levels of CK-MB
cTnI and BNP were lowered (
P
<
0.05)
and the myocardial levels of CK-MB
cTnI

MDA and HIF-1α were reduced (

the levels of myocardial CK-MB

and MDA were reduced (

and the levels of myocardial water content
serum BNP and HIF-1α were decreased. Compared with drug group
the myocardial level of BNP in the patch group was lowered (
P
<
0.05).
Conclusion
2
Preconditioning with bian-stone patches at acupoints Neiguan
Taiyuan and Renying can improve the myocardial hypoxia of model rats
reduce the degree of oxidative stress
and alleviate the myocardial injury induced by hypobaric hypoxia
providing a new treatment idea and prevention measures for acute high altitude heart disease.
