Acupotomy alleviates knee osteoarthritis in rabbit by regulating chondrocyte mitophagy Pink1-Parkin pathway.

OBJECTIVE: To investigate the effect of acupotomy, on mitophagy and the Pink1-Parkin pathway in chondrocytes from rabbits with knee osteoarthritis (KOA). METHODS: A KOA model was established via the modified Videman method. Rabbits were randomly divided into a control group (CON), KOA group and KOA + acupotomy group (Acu). Rabbits in the acupotomy group were subjected to acupotomy for 4 weeks after model establishment. The behavior of the rabbits before and after intervention was recorded. Cartilage degeneration was evaluated by optical microscopy and fluorescence microscopy. The level of mitophagy was evaluated by transmission electron microscopy, immunofluorescence and enzyme-linked immunosorbent assay (ELISA). The expression of phosphatase and tensin homolog (PTEN)-induced kinase 1 (Pink1)-Parkin mitophagy pathway components was evaluated by immunofluorescence, Western blotting and real-time polymerase chain reaction. RESULTS: In rabbits with KOA, joint pain, mobility disorders and cartilage degeneration were observed, the Mankin score was increased, collagen type Ⅱ (Col-Ⅱ) expression was significantly decreased, mitophagy was inhibited, mitochondrial function was impaired, and factors associated with the Pink1-Parkin pathway were inhibited. Acupotomy regulated the expression of Pink1-Parkin pathway-related proteins, the mitophagy-related protein microtubule-associated protein-1 light chain-3, the translocase of the outer membrane, and the inner mitochondrial membrane 23; increased the colocalization of mitochondria and autophagosomes; promoted the removal of damaged mitochondria; restored mitochondrial adenosine-triphosphate (ATP) production; and alleviated cartilage degeneration in rabbits with KOA. CONCLUSIONS: Acupotomy played a role in alleviating KOA in rabbits by activating mitophagy in chondrocytes via the regulation of proteins that are related to the Pink1-Parkin pathway.

Application of Acupotomy in a Knee Osteoarthritis Model in Rabbit.

Knee osteoarthritis (KOA) is one of the most frequently encountered diseases in the orthopedic department, which seriously reduces the quality of life of people with KOA. Among several pathogenic factors, the biomechanical imbalance of the knee joint is one of the main causes of KOA. Acupotomology believes that restoring the mechanical balance of the knee joint is the key to treating KOA. Clinical studies have shown that acupotomy can effectively reduce pain and improve knee mobility by reducing adhesion, contracture of soft tissues, and stress concentration points in muscles and tendons around the knee joint. In this protocol, we used the modified Videman method to establish a KOA model by immobilizing the left hindlimb in a straight position. We have outlined the method of operation and the precautions related to acupotomy in detail and evaluated the efficacy of acupotomy in conjunction with the theory of "Modulating Muscles and Tendons to Treat Bone Disorders" through the detection of the mechanical properties of quadriceps femoris and tendon, as well as cartilage mechanics and morphology. The results show that acupotomy has a protective effect on cartilage by adjusting the mechanical properties of the soft tissues around the knee joint, improving the cartilage stress environment, and delaying cartilage degeneration.

Study on the optimization of processing technology of honey bran-fried Atractylodis Rhizoma and its anti-gastric ulcer effect / 中国药房

OBJECTIVE To optimize the processing technology of honey bran-fried Atractylodis Rhizoma， and to compare the anti-gastric ulcer effect before and after processing. METHODS Combing with entropy-weight and technique for order preference by similarity to ideal solution model， L（9 34） orthogonal experiment design was adopted to optimize the processing technology of honey bran-fried Atractylodis Rhizoma using the comprehensive score of the contents of atractylone， β-cineole， atractylenolide Ⅲ and atractylodine as evaluation index， using the ratio of excipients to medicine， frying temperature and frying time as factors. The validation tests were conducted. The gastric ulcer model of mice was induced by intragastrical administration of anhydrous ethanol； using Compound aluminum hydroxide tablet as positive control， anti-gastric ulcer effect of Atractylodis Rhizoma was compared with that of honey bran-fried Atractylodis Rhizoma using the contents of serum inflammatory factors [interleukin-2 （IL-2）， IL-6， tumor necrosis factor-α （TNF-α）]， ulcer index and inhibitory rate of gastric ulcer as evaluation indexes. RESULTS The optimal processing technology of honey bran-fried Atractylodis Rhizoma was as follows：ratio of adjuvant and medicinal materials of 3∶10 （g/g）， frying temperature at 140 ℃ and frying time of 4 min. Results of 3 validation tests showed that the contents of 4 components （including atractylone）， in honey bran-fried Atractylodis Rhizoma processed by the optimal technology kept stable （RSDs were 3.47%-5.80%， n＝3）； the comprehensive scores were 95.53%-95.89% （RSD＝0.21%， n＝3）. Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma could increase the serum content of IL-2 in mice， but reduce serum contents of IL-6 and TNF-α to varying degrees； honey bran-fried Atractylodis Rhizoma could significantly decrease its ulcer indexes （P＜0.05 or P＜ 0.01）； the improvement effect of honey bran-fried Atractylodis Rhizoma on the above indicators was generally better than that of the same dosage of Atractylodis Rhizoma （P＜0.05 or P＜ 0.01）. The inhibitory rates of low-dose， medium-dose and high-dose Atractylodis Rhizoma and honey bran-fried Atractylodis Rhizoma to gastric ulcer in mice were 9.18%， 19.30%， 30.70%， and 50.32%， 61.39%， 53.16%， respectively. CONCLUSIONS The optimal processing technology of honey bran-fried Atractylodis Rhizoma is stable and feasible， and the anti-gastric ulcer effect of Atractylodis Rhizoma has been enhanced after being fried with honey bran.

The protective action and its mechanism of 5-hydroxy-1 H-indazole in SH-SY5 Y cells / 中国药理学通报

Aim To study the protection and possible mechanism of 5-hydroxy-1 H-indazole against 1-methyl-4-phenylpyridinium iodide ( MPP+)-induced SH-SY5 Y cell apoptosis. Methods An apoptotic model was es-tablished in human neuroblastoma SH-SY5 Y by MPP+in vitro. MTT analysis was used to evaluate the protec-tive effect of 5-hydroxy-1H-indazole. Immunochemistry and Hoechst33258 nuclear staining were used to ob-serve the neuroprotection and anti-apoptosis of 5-hy-droxy-1H-indazole. Western blot was used to detect the levels of P-tau ( Ser396 ) closely related to neuronal apoptosis and its upstream kinases:P-GSK-3β and CDK5 . Results MPP+ induced activation of GSK-3β, increase of activity of CDK5 , tau hyperphosphory-lation and neuronal cell apoptosis. However,5-hydrox-y-1 H-indazole reduced the activities of GSK-3β and CDK5,then decreased the level of tau hyperphosphory-lation and inhibited MPP+-induced SH-SY5 Y cells ap-optosis. Conclusions 5-hydroxy-1H-indazole could attenuate MPP+-induced SH-SY5 Y neuronal cell apop-tosis. Possible mechanism is that 5-hydroxy-1H-in-dazole inhibits GSK-3βand CDK5 two signal transduc-tion pathways to lower the level of tau phosphorylation, then plays a role of neuroprotection.
