ObjectiveTo explore the therapeutic mechanism of Bushen Huoxue prescription from the perspective of bone metabolism by observing the clinical efficacy of this prescription in treating femoral head necrosis （ONFH， syndrome of liver and kidney deficiency） and its influences on bone metabolism indexes： N-terminal propeptide （PINP） and β-collagen degradation product （β-CTX）. MethodSixty-six ONFH patients with the syndrome of liver and kidney deficiency in Zhengzhou Traditional Chinese Medicine Hospital of Orthopedics from December 2021 to September 2022 were selected. The patients were randomized into an experimental group and a control group by the parallel control method， with 33 patients in each group. The experimental group received Bushen Huoxue prescription orally， while the control group received Xianlinggubao Capsules orally， with a treatment cycle of 6 months. The visual analogue scale （VAS） score， Harris score， Association Research Circulation Osseous （ARCO） staging， imaging changes， quantitative scores of TCM symptoms， and serum levels of PINP and β-CTX were determined before and after treatment. The occurrence of adverse events and reactions was recorded. ResultThe total response rate in the experimental group was 83.87% （26/31）， which was higher than that （68.75%， 22/32） in the control group （Z=-2.096， P<0.05）. After treatment， the single and total scores of TCM symptoms， VAS score， and β-CTX level decreased in the two groups （P<0.05）. Moreover， the decreases in the scores of hip pain， lower limb mobility， soreness of waist and knees， and lower limb flaccidity， total score of TCM symptoms， VAS score， and β-CTX level in the experimental were larger than those in the control group （P<0.05）. After treatment， the imaging results showed no significant improvement in the two groups. The Harris score and PINP level in both groups increased after treatment （P<0.05）， and the increases were more obvious in the experimental group than in the control group （P<0.05）. No serious adverse event or adverse reaction appeared during the observation period. ConclusionBushen Huoxue prescription can relieve pain and TCM symptoms and improve the hip joint function in treating ONFH patients with the syndrome of liver and kidney deficiency. It can inhibit the development of ONFH， increase PINP， and decrease β-CTX. No obvious side effect appears during the clinical observation period， which shows that Bushen Huoxue prescription has good safety.

Bushen Huoxue Prescription Replenishes Diminished Ovarian Reserve in Rats Through PI3K/Akt/mTOR Signaling Pathway / 中国实验方剂学杂志

Objective:To explore the mechanism of Bushen Huoxue prescription in regulating the related factors in phosphatidylinositol 3-kinase （PI3K）/ protein kinase B （Akt）/ mammalian target of rapamycin （mTOR） pathway and improving ovarian reserve function of rats with diminished ovarian reserve （DOR）. Method:Sixty DOR model rats were duplicated by Ataya method （intraperitoneal injection of cyclophosphamide） and then randomized into the model group， estradiol valerate （0.000 9 g·kg^-1） group， and high- （33 g·kg^-1）， middle- （16.5 g·kg^-1） and low-dose （8.25 g·kg^-1） Bushen Huoxue prescription groups， with 12 rats in each group. Another 12 healthy rats were classified into the blank control group. The rats in each group were given the corresponding drugs by gavage， while those in the blank control group and model group received the same volume of normal saline， once per day， for 14 successive days. After treatment， the ovarian tissue was stained with hematoxylin-eosin （HE） for observing the changes in quantities of primary follicles， mature follicles， and total follicles under a light microscope， followed by the detection of vascular endothelial growth factor （VEGF） expression in the ovarian tissue by immunohistochemistry. The protein expression levels of PI3K， Akt， mTOR， and cysteine-dependent aspartate-directed protease-3 （Caspase-3） in the ovarian tissue were assayed by Western blot， whereas the mRNA expression levels of PI3K， Akt， and mTOR were measured by Real-time polymerase chain reaction （Real-time PCR）. Result:As revealed by comparison with the blank control group， the quantities of mature follicles and total follicles in the ovarian tissue of model group were significantly reduced （<italic>P</italic><0.05， <italic>P</italic><0.01）. The protein expression levels of VEGF and Caspase-3 in the ovarian tissue were increased （<italic>P</italic><0.05）， while the protein and mRNA expression levels of PI3K， Akt， and mTOR were decreased （<italic>P</italic><0.05， <italic>P</italic><0.01）. Compared with the model group， Bushen Huoxue prescription at the high and middle doses elevated the quantities of mature follicles and total follicles to varying degrees （<italic>P</italic><0.05， <italic>P</italic><0.01）， and VEGF increased most significantly in the middle-dose Bushen Huoxue prescription group （<italic>P</italic><0.05）. Caspase-3 in the low-， middle-， and high-dose Bushen Huoxue prescription groups and the western medicine group declined. The protein and mRNA expression levels of PI3K， Akt， and mTOR were up-regulated in the middle- and high-dose Bushen Huoxue prescription groups （<italic>P</italic><0.05， <italic>P</italic><0.01）， and the levels in the middle-dose Bushen Huoxue prescription group were closer to those in the blank control group. Conclusion:Bushen Huoxue prescription effectively improves the ovarian reserve function of rats with DOR and increases the number of follicles possibly by up-regulating VEGF expression in the ovarian tissue， activating the PI3K/Akt/mTOR signaling pathway， and regulating the content of Caspase-3.
