Effect of RANKL on chondrocyte differentiation of temporomandibular joint FAN Bao-ting, XU Wei-feng, SHEN Pei, LI Hui-ping, ZHAO Hua-qiang, ZHANG Shan-yong 2017, 15 (2):  97-102.  doi: 10.19438/j.cjoms.2017.02.001 Abstract ( 479 )   PDF (4122KB) ( 505 )   PURPOSE : This study was aimed to identify a novel therapeutic way for joint cartilage degeneration. METHODS : By using ATDC5 chondrogenic cells and bovine cartilages, we studied the role of RANKL in cartilage degeneration in vitro. The protein expression of MMP13, RANK, RANKL and ADAMTS5 was detected using Western blot. The mRNA expression of Col2a1, Col10a, MMP13, RANK and ADAMTS5 was detected using RT-qPCR. Degeneration of cartilage was analyzed by safranin O and alician blue staining and Mankin score. The data were analyzed by paired t test using SPSS17.0 software package. RESULTS : The results of real time PCR confirmed that both RANK and RANKL were dynamically expressed in ATDC5 cells during all differentiation phases (P<0.05). RANK protein expression was significantly enhanced by RANKL treatment for 48 h in comparison to that for 0h. The mRNA and protein level of ADAMTS5 was significantly increased as stimulated by RANKL compared with the control over time (P<0.05). In addition, vacuolation and degeneration were observed in bovine cartilages with RANKL stimulation (P<0.05). CONCLUSION S: RANKL contributes to cartilage degeneration in condylar resorption and inhibition of this pathway may be a useful strategy for condylar resorption treatment.

METHODS : Three mandibular premolars and one molar on both sides of the jaw in 3 dogs were extracted. Six months after extraction, three implants were inserted into each side, and alveolar bone defects (4 mm×4 mm×4 mm in size) were produced. 24 implants in total 6 sides were assigned to 3 groups and covered with different membranes as follows, group A: implant+Bio-Oss+Ti-mesh; group B: implant+Bio-Oss+Bio-Gide, group C: implant+Bio-Oss+Ti-mesh+Bio-Gide. The claps were sutured over the membranes to complete the wound closure. The animals were sacrificed after 6 months, and non-decalcified histological specimens of the implants and surrounding tissues were prepared. Micro-CT scanning was carried out to test the results. SPSS17.0 software package was used for statistical analysis. RESULTS : Micro-CT with three-dimensional reconstruction revealed that bone regeneration in group C was significantly better than the other two groups (P<0.01), which indicated faster new bone deposition. CONCLUSION S: Combination of Bio-Gide membrane and Ti-mesh may get a better bone regeneration than Ti-mesh or Bio-Gide used alone. References | Related Articles | Metrics

Relationship between different doses of zoledronic acid and bisphosphonate-related osteonecrosis of jaw: an experiment study in rats SHEN Ya-jun, DU Ming-yan, GUAN Jian, LI Mao, ZHAO Yan-tao, GE Cheng 2017, 15 (2):  115-120.  doi: 10.19438/j.cjoms.2017.02.004 Abstract ( 633 )   PDF (3934KB) ( 411 )   PURPOSE : To investigate the relationship between different doses of zoledronic acid (ZA) and bisphosphonate-related osteonecrosis of jaw (BRONJ) by establishing the model of osteonecrosis of jaw in rats with different doses of ZA. METHODS : Forty SD rats were divided into 4 groups (ten rats in each group), the rats in 4 groups were injected intraperitoneally with 33, 66 and 132 μg/kg ZA or normal saline (control), respectively, three times a week for 12 weeks, and the weight was measured weekly. In the ninth week, all rats was subjected to extraction of the first left mandibular molar. After the last injection, all rats were sacrificed. The jaws were clinically, radiologically and histopathologically examined. Independent samples t test was performed using SPSS19.0 software package. RESULTS : The weight of rats in the experimental groups was significantly lower than that in the control group after extraction (P<0.05). 86.7% rats in the experimental group were observed with unclosed mucosa; however, mucosa on extraction sites in the control group healed completely (P<0.05). Radiological examination revealed radiolucent areas on the extraction sites in the experimental groups were significantly greater than those in the control group (P<0.05). Histopathological examination showed 70% rats in the experimental group developed osteonecrosis,especially in higher dose group,while osteonecrosis was not found in the control group (P<0.05). CONCLUSION : The study showed severe BRONJ was closely associated with high dose of ZA. Low dose of ZA just induces minor BRONJ, or is unable to induce BRONJ. Thus, Patients treated with high dose of ZA are facing great risk of developing BRONJ. References | Related Articles | Metrics

Effects and mechanism of quercetin on proliferation and apoptosis of human adenoid cystic carcinoma cell line ACC-M MI Jing, ZHANG Ming-bin, WAN Guang-yong 2017, 15 (2):  121-126.  doi: 10.19438/j.cjoms.2017.02.005 Abstract ( 366 )   PDF (3998KB) ( 442 )   PURPOSE : To observe the effect of quercetin on human adenoid cystic carcinoma cells (ACC-M) proliferation and apoptosis. METHODS : CCK-8 staining was used to detect different concentrations of quercetin on ACC-M cell proliferation inhibition, the inhibition rate and IC50 were calculated; flow cytometry was used to detect ACC-M cell apoptosis rate and cell cycle distribution; Survivin mRNA of ACC-M cells was detected by RT-PCR. The difference between each group was analyzed with SPSS20.0 software package. RESULTS : Quercetin inhibited ACC-M cell growth obviously in a concentration dependent manner. The IC50 was 151.12 μmol/L (P<0.05); annexin V/PI double staining assay showed that quercetin can induce apoptosis of ACC-M cells in a dose and time dependent manner (P<0.05); PI staining assay showed that quercetin played an important role in G2/M cells, which were specifically arrested in G2/M phase. RT-PCR showed the quercetin concentration was negatively related with survivin mRNA in ACC-M cells and 200 μmol/L quercetin could inhibit the expression of Survivin mRNA significantly. CONCLUSION S: Quercetin can inhibit the proliferation of ACC-M cells and induce its apoptosis in a time and dose dependent manner by down-regulating the level of Survivin.

METHODS : TSCC cell lines SCC9 and CAL27 were cultured under hypoxia (1% O2) or normoxia (20% O2) for 48 h. Western blot and qRT-PCR were used to detect expression of vimentin, fibronectin, E-cadherin and HIF-1α at protein and mRNA level, respectively. Transwell assay was used to detect cell invasion. After transfected HIF-1α with siRNA, HIF-1α, vimentin, fibronectin and E-cadherin expression, as well as invasion, were furthered detected in SCC9 and CAL27 cells. SPSS 13.0 software package was used for statistical analysis. RESULTS : Both SCC9 and CAL27 cells under hypoxia for 48 h showed upregulated vimentin and fibronectin, downregulated E-cadherin and upregulated HIF-1α expression, as well as increased invasion. After knocking down of HIF-1α with siRNA, HIF-1α, vimentin and fibronectin were significantly downregulated but E-cadherin was upregulated in SCC9 and CAL27 cells under hypoxia, with decreased invasion. CONCLUSION : Hypoxia induces epithelial-to-mesenchymal transition and metastasis of TSCC via upregulating HIF-1α. References | Related Articles | Metrics

METHODS : Six cases with severe skeletal Class Ⅱ malocclusion and narrow maxillary dental arch secondary to bilateral ICR were included in this study, and they were treated with mandibular distraction osteogenesis and surgery-assisted rapid maxillary expansion. The path and magnitude of distraction were simulated using computer-aided surgical simulation technique. The outcome of distraction, the necessity of secondary surgery and stability were evaluated through 4 aspects: profile, occlusion, temporomandibular joint (TMJ) condition and sleep respiratory function at T0, T1, T2 and T3. CT, TMJ questionnaire, MRI of TMJ and PSG were acquired at this 4 time points. RESULTS : Three cases finished all treatments. The distraction magnitudes were 13.0mm, 6.7mm and 8.1mm, respectively. Chin advanced in genioplasity for 7.2 mm, 0 and 11 mm, respectively. Maxillary dental arch widened 5.3mm, 7.3 mm and 4.9 mm, respectively. Polysomnography data revealed that severe obstructive sleep apnea hypopnea syndrome was cured. Skeletal malocclusion was effectively corrected in all 3 cases and there was no obvious relapse during remodeling phase. TMJ condition remained stable. CONCLUSION S: Mandibular DO and SARME approach can effectively correct severe skeletal Class II malocclusion and narrow maxillary dental arch secondary to bilateral ICR. Using CASS technology to simulate the magnitude and path of distraction, the outcomes are more stable and predictable. References | Related Articles | Metrics

Observation of long-term effect of autologous artery to repair parotid duct defect WANG Wei, CHI Yu-feng, TAN Xi-tao, WANG Pei, FEI Xiao-dong, WANG Xiao-xia. WANG Wei, CHI Yu-feng, TAN Xi-tao, WANG Pei, FEI Xiao-dong, WANG Xiao-xia 2017, 15 (2):  176-179.  doi: 10.19438/j.cjoms.2017.02.016 Abstract ( 428 )   PDF (2855KB) ( 806 )   PURPOSE : To evaluate the effect of autologous artery in repair of parotid duct defect. METHODS : From August 2003 to December 2012, six patients with parotid duct defect were reconstructed with autologous artery. The clinical data were retrospective analyzed to evaluate the effect based on clinical observation and parotid sialography. All patients were followed up for 1 month to 9 years. RESULTS : During the follow-up period of 1 month to 2 years, no swelling was present in the parotid gland of 6 patients, the parotid duct were patent, the secretory function of parotid were normal. During the follow-up period of 2-9 years, bilateral parotid gland seemed symmetric. The parotid duct in 2 patients exerted a small amount of saliva, the parotid duct reconstructed with autologous artery showed stenosis through parotid sialography. Three patients had no salivary secretion. One patient was lost follow-up. CONCLUSION S: Using autologous artery to reconstruct parotid duct can achieve a good short-term effect, but the long-term results were not ideal, therefore, parotid duct isn't suitable to be reconstructed with autologous artery.
