OBJECTIVETo observe the effect and mechanisim of zoledronate sodium on periprosthetic osteolysis in rat induced by polyethylene particles.
METHODSTotal 30 adult male SD rats, weighting from 250 to 300 g, were selected and randomly divided into three groups: blank control group, model control group and zoledronate sodium group respectively, 10 animals for each group. No treatment was performed in the blank control group. In model control group and zoledronate sodium group, the modle of periprosthetic osteolysis in rats were made by implanting polyethylene particles and titanium rods into their right femurs. After operation, rats in zoledronate sodium group were administered with zoledronate sodium (0.1 mg/kg each week) through subcutaneous injection for 8 weeks, then the blood was obtained and all experimental animals were sacrificed to get the right femur specimens. The femur BMD, IL-1β, IL-6, TNF-α, serum TRACP5b and CTX-I were detected.
RESULTSCompared with the model control group, the femur BMD was increased, while IL-1β, IL-6 and TNF-α were all decreased in zoledronate sodium group; the serum TRACP5b and CTX-I level were both reduced in zoledronate sodium group.
CONCLUSIONThe zoledronate sodium could effectively inhibit periprosthetic osteolysis in rats induced by polyethylene particles, which might be realized by inhibiting the activity of osteoclasts and the expression of IL-1β, IL-6 and TNF-α. It provides a new method to treat periprosthetic osteolysis of the artificial joint prosthesis.

OBJECTIVE To investigate the autophagic effect of the compounds from the Chinese medicinal herbs, Radix polygalae as a potential neuroprotective agent that enhances the clearance of mutant Huntingtin and α- synuclein in PC- 12 cells. METHODS Radix polygalae was extracted with 75% ethanol using refluxing method, and its quality was assayed by UHPLC-TOF-MS. The autophagic effect of Radix polygalae extract, and its major components including polygalacic acid, senegenin and onjisaponin B were investigated using the green fluorescent protein-light chain 3 (GFP-LC3) autophagy detection and Western blot platforms for detecting the autophagic markers, GFP-LC3 puncta formation and LC3 II expression. The degradation of A53T α- synuclein and the inhibition ofα-synuclein oligo merization related to the Parkinson disease were assayed using Western blot and flow cytometer analysis, respectively. While the cytotoxicity and the degradation of the mutant Huntingtin associated with the Huntingtin disease were investigated using MTT method and flow cytometer analysis. RESULTS Radix polygalae ethanol extract and onjisaponin B improved the GFP-LC3 puncta formation and expression of LC3Ⅱ with time and dose manner, and this induction was activated via AMPK-mTOR and Atg 7 gene pathway. Furthermore, the clearance of α-synuclein and mutant Huntingtin was enhanced via autophagy induction with the treatment of Radix polygalae ethanol extract and onjisaponin B. CONCLUSION Findings in the current study provide detailed insights into the protective mechanism of a novel autophagy inducer, onjisaponin B, which is valuable for further investigation as a new candidate agent for modulating neurodegenerative disorders through the reduction of toxicity and clearance of mutant proteins in the cellular level.

ObjectiveTo investigate the protective effect of paraoxonase 1 (PON1) gene against liver oxidative stress injury in mice due to dichlorvos poisoning.Methods Experiment 1: 12 male Balb/c mice were randomly divided into three groups, with 4 mice in each group: control group, green fluorescent protein lentivirus control group (Lv-GFP group), and recombinant PON1 lentivirus group (Lv-PON1 group). 2×107 TU of Lv-GFP or Lv-PON1 was transfected via tail vein, while normal saline was given to those in control group. Blood was collected on 0, 1, 3, 5, 7, 9 days via fundus venous plexus for the assay of serum PON1 activity. PON1 mRNA and protein expression levels were respectively determined by reverse transcription-polymerase chain reaction (RT-PCR) and Western Blot on the 3rd post-lentivirus transfection day. Experiment 2: according to the random number table method, another 96 male Balb/c mice were divided into four groups of 24 mice in each control group, dichlorvos group, Lv-GFP intervention group, and Lv-PON1 intervention group. Lv-GFP or Lv-PON1 was transfected via tail vein followed by intraperitoneal injection of dichlorvos 9 mg/kg, while those in control group were given normal saline. Six mice in each group were sacrificed respectively at 6, 12, 24, 48 hours, and liver tissue was collected. PON1 mRNA and nuclear factor E2-related factor 2 (Nrf2) mRNA expression levels were determined by RT-PCR, and PON1 protein level was determined by Western Blot. The content of malondialdehyde (MDA) and glutathione (GSH) in the liver tissue were determined by chemical colorimetry. The activity of superoxide dismutase (SOD) and catalase (CAT) were measured by double antibody sandwich enzyme linked immunosorbent assay (ELISA).Results Experiment 1: after Lv-PON1 was transfected to normal mice, PON1 activity in serum gradually increased and maintained a high level on 3rd day, while that of the control group and Lv-GFP group showed a normal low level. On the 3rd post-lentivirus transfection day, PON1 mRNA and PON1 protein expressions in liver were significantly higher than those of control group and Lv-GFP group. Experiment 2: compared with control group, the mice in dichlorvos group showed significant decreases in PON1 mRNA, PON1 protein, Nrf2 mRNA as well as GSH, SOD, CAT levels at 6 hours [PON1 mRNA (gray value):0.237±0.075 vs. 0.674±0.011, PON1 protein (gray value): 0.602±0.086 vs. 0.998±0.124, Nrf2 mRNA (gray value): 0.089±0.012 vs. 0.126±0.010, GSH (mg/g): 3.84±0.33 vs. 5.52±0.40, SOD (μg/g): 0.383±0.040 vs. 0.564±0.052, CAT (ng/g): 7.32±1.28 vs. 12.46±1.54, allP< 0.05], and remarkable increase in MDA content (nmol/g: 7.78±0.41 vs. 2.34±0.25,P< 0.05). With the extension of time, PON1 mRNA, PON1 protein, Nrf2 mRNA and GSH, SOD, CAT levels gradually increased, MDA content gradually decreased, Nrf2 mRNA expression level had risen to the level of control group at 24 hours (0.133±0.019 vs. 0.126±0.009,P> 0.05), and it was higher than that of the control group at 48 hours (0.206±0.028 vs. 0.124±0.010,P< 0.05). Compared with that of the dichlorvos group, Lv-PON1 intervention group showed a significant increase in PON1 mRNA, PON1 protein, Nrf2 mRNA and GSH, SOD, CAT levels [PON1 mRNA (gray value): 0.726±0.021 vs. 0.237±0.075, PON1 protein (gray value): 0.739±0.050 vs. 0.602±0.086, Nrf2 mRNA (gray value): 0.158±0.007 vs. 0.089±0.012, GSH (mg/g): 4.30±0.22 vs. 3.84±0.33, SOD (μg/g): 0.454±0.062 vs. 0.383±0.040, CAT (ng/g): 8.98±1.02 vs. 7.32±1.28, allP< 0.05], and a decrease in MDA content (nmol/g: 6.56±0.44 vs. 7.78±0.41,P< 0.05).Conclusion Regulation of PON1 gene can reduce MDA content, enhance SOD and CAT activities, increase GSH content, and it may also up-regulate Nrf2 mRNA expression to play a protective effect against oxidative stress of liver injury induced by dichlorvos poisoning.
