目的
2
观察针刺联合脐带间充质干细胞对卵巢早衰大鼠卵巢储备功能的影响。
方法
2
70只雌性SD大鼠随意分为造模组和正常组。造模组大鼠给予去氧乙烯基环己烯(80 mg/kg)腹腔注射,制备卵巢早衰大鼠模型。造模成功后,再将其随意分为模型组、针刺组、干细胞组、联合治疗组,每组12只,剩余12只正常大鼠为空白组。针刺组针刺“关元”“气海”“足三里”;干细胞组在干预的第1、8天,经大鼠尾静脉注入人类脐带间充质干细胞液0.5 mL(细胞数为2.5×10
6
个);联合治疗组进行针刺和尾静脉注入人类脐带间充质干细胞液。干预后,检测大鼠卵巢湿重和卵巢指数;酶联免疫吸附测定检测血清睾酮(T)、雌二醇(E
2
)、促卵泡激素(FSH)、黄体生成素(LH)和抗米勒管激素(AMH)水平及抗氧化指标丙二醛(MDA)、谷胱甘肽(GSH)、超氧化物歧化酶(SOD)水平;HE染色检测各组大鼠卵巢形态结构变化;免疫组织化学法及蛋白质印迹法检测卵巢组织中蛋白激酶B(Akt)、磷酸化蛋白激酶B(p-Akt)、B淋巴细胞瘤-2(Bcl-2)、Bcl-2相关X蛋白(Bax)的蛋白表达水平。

结论
2
针刺、干细胞和联合治疗对卵巢早衰大鼠均能起到积极治疗作用,均能改善卵巢早衰大鼠卵巢储备功能,促进卵巢颗粒细胞增殖,抑制卵泡凋亡;且联合治疗效果优于单纯针刺和干细胞治疗。
Objective
2
We aimed to observe the effect of acupuncture combined with umbilical cord mesenchymal stem cells on ovarian reserve function in rats with premature ovarian failure.
Methods
2
Seventy female Sprague-Dawley rats were divided into the modeling group and the normal group. Modeling group rats were injected intraperitoneally with vinyl cyclohexene (80 mg/kg) to establish a rat model of premature ovarian failure. After the model was successfully established
the rats were divided into the model group
the acupuncture group
the stem cell group
and the combined treatment group (12 rats per group). The remaining 12 normal rats served as the blank group. The acupuncture group was treated with acupuncture at RN4
RN6 and ST36. In the stem cell group
0.5 mL human umbilical cord mesenchymal stem cell fluid was injected into the tail vein of rats on the first and eighth days of intervention (2.5×10
6
cells). Rats in the combined treatment group received acupuncture and tail vein injection of human umbilical cord mesenchymal stem cell fluid. After the intervention
wet ovarian weight and the ovarian index were determined. The contents of serum testosterone (T)
estradiol (E
2
)
follicle stimulating hormone (FSH)
luteinizing hormone (LH)
anti-Mullerian hormone (AMH) and the contents of antioxidant indices malondialdehyde (MDA)
glutathione (GSH)
superoxide dismutase (SOD) were detected by ELISA. HE staining was used to detect the morphological changes of ovaries in each group. The relative expression levels of Akt
p-Akt
Bcl-2 and Bax in ovaries were detected by immunohistochemistry and Western blotting.
Results
2
Compared with the blank group
the wet ovarian weight and ovarian index of the model group were decreased significantly (
P
<
0.01). The serum levels of LH
T
FSH
and MDA were increased (
P
<
0.05
P
<
0.01)
while the levels of E
2
AMH
GSH and SOD were decreased (
P
<
0.05
P
<
0.01). HE staining showed that the number of mature follicles in the ovary was decreased and the number of atretic follicles was increased. The relative expression of Akt
p-Akt and Bcl-2 in ovarian tissue was decreased (
P
<
0.05
P
<
0.01)
and the relative expression of Bax was increased (
P
<
0.01). Compared with the model group
the wet ovarian weight and ovarian index of rats in the acupuncture group
stem cell group and combined treatment group were increased (
P
<
0.05
P
<
0.01). The serum levels of T and FSH were decreased (
P
<
0.05
P
<
0.01). The serum levels of E
2
AMH
GSH and SOD were increased (
P
<
0.05
P
<
0.01). HE staining showed a decrease in ovarian abnormalities. In ovarian tissue
the positive expression of p-Akt and Bcl-2 and the relative expression of these proteins were increased (
P
<
0.05
P
<
0.01)
while the positive expression of Bax and the relative expression of this protein were decreased (
P
<
0.05
P
<
0.01). Compared with the acupuncture group and the stem cell group
the wet weight of ovaries in the combined treatment group was increased significantly (
P
<
0.05)
the serum levels of T and FSH were decreased significantly (
P
<
0.05
P
<
0.01)
the level of AMH was increased significantly (
P
<
0.05
P
<
0.01)
and the positive expression of Akt was increased significantly (
P
<
0.05). Compared with the acupuncture group
the levels of SOD and GSH in the combined treatment group were increased significantly (
P
<
0.01)
and the relative expression of Bax was decreased significantly (
P
<
0.01). Compared with the stem cell group
the serum MDA level in the combined treatment group was decreased significantly (
P
<
0.05).
Conclusion
2
Acupuncture
stem cell treatment
and combined treatment can play an active role in the treatment of premature ovarian failure rats
improve the ovarian reserve function of premature ovarian failure rats
promote the proliferation of ovarian granulosa cells
and inhibit apoptosis in follicles. The effect of combined treatment is better than that of acupuncture or stem cell therapy only.
