Objective To observe the expression of osteoprotegerin (OPG), receptor activator of nuclear factor κβ ligand(RANKL) and receptor activator of nuclear factor κβ (RANK) in bone tissue of rats with chronic fluorosis and to explore the relation between OPG/RANKL/RANK system and bone damage in chronic fluoride poisoning rat and the antagonism effects of Danlan Xianpeng capsule. Methods SD rats were randomly divided into six groups according to body weight (equal male and female in each group): fluorosis group, high dose drug group, medium dose drug group, low dose drug group, control group, borax group(positive control), 12 rats in each group. The control group drank tap water and the remaining 5 experimental groups consumed 50 mg/L fluoride water, and high, medium and low doses drug group took Danlan Xianpeng capsule at doses of 0.8,0.4,0.2 g/kg,borax group took borax at dose of 0.8 g/kg. OPG, RANKL, RANK protein in rat tibial metaphysis was detected by immunohistochemistry at the 6 month. Results Compared with the control group(173.79 ± 5.23, 174.17 ± 5.01,155.63 ± 7.11), the expressions of OPG, RANKL were increased and the expression of RANK was decreased in fluorosis group(156.83 ± 5.80, 157.74 ± 6.70, 173.92 ± 4.37), the difference was statistically significant (all P < 0.05). Compared with the fluorosis group, the expression of OPG and RANKL were decreased and the expression of RANK was increased in high-dose drug group, middle-dose drug group(169.67±5.07, 168.08 ± 5.05,162.12 ± 4.24, 170.78 ± 5.01, 168.41 ± 7.19, 166.69 ± 5.78, all P < 0.05). Compared with the borax group (167.27 ± 4.08, 167.85 ± 5.01, 166.14 ± 3.95), the expression of OPG and RANKL was increased in the low-dose drug group (163.40 ± 4.11, 159.49 ± 5.78), the expression of RANK was increased in the high-dose drug group (162.12 ± 4.24) and decreased in the low-dose drug group(171.54 ± 8.06), the difference was statistically significant (all P < 0.05). Conclusions Chronic fluoride poisoning can cause increased bone turnover and enhance the activity of osteoelastic absorption by increasing RANKL. Danlan Xianpeng capsule can affect bone remodeling through the OPG/RANKL/RANK system, and antagonises bone damage caused by fluoride.

Neurodegenerative disease is characterized by progressive loss of neurons in specific brain regions that results in neuronal dysfunction of the central nervous system. Although the pathological mechanism is not fully established, the activation of glial cells mediated neuroinflammation appears to be involved. Heat shock protein 70 (HSP70) is originally described as intracellular chaperone, which plays an important role in protein quality control in cells. However, recent study showed that up-regulation of HSP70 had anti-inflammatory effects in the brain. HSP70 protected neurons from damage and improved neurological function by decreasing inflammatory response as indicated by inactivation of glial cells and inhibition of pro-inflammatory cytokine release. So it is of great significance to find new compounds targeting at HSP70 as neuroprotective agents to delay the progress of neurodegenerative disease. This review will focus on the role of HSP70 in neuroinflammation and the recent advances in using HSP70 as a target for the treatment of neurodegenerative disease.

7. Mechanism study of orientin protecting rat heart from myocardial ischemia/reperfusion injury based on mitochondrial quality control
Chinese Traditional and Herbal Drugs 2018;49(18):4337-4343
Objective To investigate the regulation effects of orientin on mitochondrial quality control in cardiomyocytes of rats with myocardial ischemia/reperfusion injury (MIRI). Methods A total of 75 Sprague-Dawley male rats were randomly divided into five groups: sham group, model group, and orientin preconditioning groups (1.0, 2.0, and 4.0 mg/kg). Except for sham group, all rats were exposed to modeling of MIRI with ligation of left anterior descending coronary artery (LADCA) for 30 min, and then releasing for 120 min. Mitochondrial membrane potential (MMP) and opening of mitochondrial permeability transition pore (mPTP) were detected by Microplate Reader; Activity of mitochondrial respiratory chain complexes I-IV was detected by Spectrophotometer; Cardiomyocyte apoptosis was detected by TUNEL method; Apoptosis and mitophagy related proteins were detected by Western Blot and the interaction between Parkin and p62 on mitochondria were detected by Co-IP. Results Orientin significantly restored MMP, mPTP opening threshold and activity of mitochondrial respiratory chain complexes I-IV, and reduced cardiomyocyte apoptosis. Additionally, orientin can dramatically inhibit the protein expression level apoptosis and mitophagy related proteins and weaken the interaction between Parkin and p62. Conclusion Orientin has a significant protective effect on cardiomyocyte mitochondria in MIRI rats. Its underlying mechanism is related to inhibition of hyperactivity of mitophagy in cardiomyocytes via Parkin-dependent and Parkin-independent signaling pathways.

Chinese Journal of Tissue Engineering Research 2018;22(11):1792-1797
BACKGROUND: In the past ten years, because of the complications such as adjacent vertebral diseases after the discectomy and interbody fusion fixation, the artificial cervical disc replacement gradually replaces part of intervertebral disc and interbody fusion with internal fixation, and has become a new choice of a surgical treatment of spinal degenerative diseases resection; however, heterotopic ossification after the artificial intervertebral disc replacement as a postoperative problem has attracted the field attention. OBJECTIVE: To review the domestic and foreign research progress on heterotopic ossification after artificial disc replacement. METHODS: The first author retrieved PubMed database, Chinese Journal Full-text Database for related articles published from November 1973 to May 2017. The key words were "cervical vertebrae, artificial disc replacement, heterotopic ossification, research progress". A total of 216 articles were retrieved, and 45 articles met the inclusion criteria. RESULTS AND CONCLUSION: (1) Heterotopic ossification had a certain occurrence rate after artificial disc replacement. The susceptible factors and preventive measures were still controversial. (2) Future research regarding heterotopic ossification after artificial intervertebral disc replacement mainly focused on the development of biomechanics, molecular level and degenerative change. It is expected that in the near future, artificial disc that is more suitable for human spine biomechanics environment will appear; heterotopic ossification after artificial disc replacement will be more in-depth research.
