We studied the function of connexin 43 (Cx43) gene in Xiao Meishan swine bone marrow mesenchymal stem cells (BMSCs) resulting from overexpression. Cx43 eukaryotic expression vector (pEGFP-Cx43) was constructed and transfected into BMSCs by nucleofector, after detecting the transfection efficiency; the expression of Cx43 was verified by RT-PCR, immunofluorescence and western blotting. Furthermore, we detected its cell cycle and apoptosis through flow cytometry. Our results show that pEGFP-Cx43 plasmid was successfully constructed, and green fluorescence in pEGFP-Cx43 transfected BMSCs was highly expressed with 60% transfection efficiency. In transgenic Xiao Meishan swines BMSCs, the expression level of Cx43 mRNA and protein were up-regulated. Meanwhile, the ability of cell proliferation was significantly increased, and the apoptosis rate was significantly reduced. Taken together, Cx43 overexpression could promote the proliferation of Xiao Meishan swine's BMSCs and markedly reduce their apoptosis, which provides evidence for in vivo research.

BACKGROUND:Studies on high glucose exposure in human periodontal ligament cel s usual y focus on the biological behaviors, pathways and secretory factors, but whether the metabolic memory is involved is little known. OBJECTIVE:To investigate the metabolic memory of high glucose exposure in human periodontal ligament cel s. METHODS:Human periodontal ligament cel s were primarily cultured and identified. Cel s at 5-8 passages were selected and randomized into four groups. Group A (controls):DMEM containing 5.5 mmol/L glucose for 8 days;group B (5-day memory group):DMEM containing 35 mmol/L glucose for 3 days and DMEM containing 5.5 mmol/L glucose for 5 days;group C (3-day memory group):DMEM containing 35 mmol/L glucose for 5 days and DMEM containing 5.5 mmol/L glucose for 3 days;group D (8-day high glucose group):DMEM containing 35 mmol/L glucose for 8 days. The cel proliferation was detected by cel counting kit-8, the cel apoptosis was determined by flow cytometry, and the levels of total proteins and alkaline phosphatase were investigated using ELISA. RESULTS AND CONCLUSION:Compared with the control group, the cel proliferation in the other three groups was significantly reduced (P<0.05), the number of apoptotic cel s was significantly increased, while the levels of total proteins and alkaline phosphatase were significantly decreased (P<0.05). These results suggest that high glucose causes persistent changes in human periodontal ligament cel s by inhibiting cel viability, increasing the apoptosis and downregulating the levels of the total proteins and alkaline phosphatase

Objective To evaluate the clinical efficacy of intra-articular injection of ozone in collagen-induced arthritis (CIA) rats and to assess its effects on serum receptor activator of nuclear factor κB ligand (RANKL) and osteoprotegerin (OPG) levels. Methods Forty weight age malched Wistar rats were randomly divided into normal control group (normal group), the CIA model group (CIA group), ozone (O 3 group), and methotrexate (MTX group). In addition to the normal control group, Freund's complete adjuvant and bovine type Ⅱ collagen were injected to establish the rat model of CIA. After the model was sucessfully developed, double ankle injection concentration ozone group of 40 μg/ml of O3 each 1 ml, 1 times a week, a total of injection for 3 weeks for the experimenal group. MTX group of 0.9 mg/kg was injected 1 times a week for 3 weeks for the MTX group. Degree of foot swelling was measured, and radiographic assessment of arthritis index (AI) score was performed. One week after treatment, angular vein blood was collected for the rats after the intervention, flow multi-factor detection technology was used to test each rat. T test or Wilcoxon rank test was used to compare the difference between groups. Results ① After 3 week administration with O3, dcgree of foot swelling, and AI of the O3 group was reduced significanly than the CIA group during the same period (foot swelling degree: O3 group: (4.21±0.14) ml, CIA group (9.12±0.17) ml, T=64.08, P=0.00; AI O3 group: [(2.97± 0.18) ml, CIA group: 5.76 ±0.13, T=37.24, P=0.00], and X-ray showed joint damage was alleviated. ② The serum level of RANKL in the CIA group was significantly higher than of the normal group [CIA model group 1890.70(797.03, 10571.94)], normal group [74.46(29.21, 95.37), T=43, P=0.005] during the same period; The serum level of RANKL in the O3 group was significantly lower than the CIA group [O3 group 28.09 (14.11, 207.30), CIA group 1890.70 (797.03, 10571.94), T=39, P<0.05]; RANKL level of the Ozone group when compared with MTX group, was not statistically significantly difference (T=52, P>0.05).③Serum RANKL/OPG of the CIA group was significantly higher than that of the normal group during this period, the difference was statistically significant [CIA group 250.68(42.33, 2959.78), normal group 4.32(3.16,5.30), T=36, P<0.01);The serum level of RANKL/OPG in the O3 group was significantly lower than the CIA group [O3 treatment group 5.10 (3.38, 6.64), CIA group 250.68 (42,33, 2959.78), T=36, P<0.01]; There was no statistically significant difference of the serum RANKL/OPG between the O3 group and the MTX group (T=62.5, P>0.05). Conclusion Intra-articular injection of concentration of 40 μg/ml of O3 can reduce RA rat joint swelling degree, which may relate to the mechanism that O3 can lower levels of serum RANKL and RANKL/OPG ratio, reduce osteoclast formation and activation.

Objective To investigate the association of interleukin-6 (IL-6) with depression using meta analysis. Methods A systematic literature search was conducted to examine depression and interleukin-6 in Chinese patients us-ing“depression”and“interleukin-6”in Databases including PubMed, CBM, VIP, CNKI and WanFang Data. A me-ta-analysis was performed to analyze correlation between depression and interleukin-6 using RevMan 5.2.8 software. Results A total of 9 studies were recruited, involving 432 depression patients and 277 healthy controls. The results of meta-analysis showed that concentration of IL-6 was higher in depression patients than in healthy controls(SMD=1.48, 95%CI:0.78~2.18,P<0.05). Subgroup analysis in the first-episode subgroup and the non first-episode subgroup showed that concentration of interleukin-6 was higher in depression patients than that in controls [the first-episode subgroup (SMD=1.94,95%CI:0.07~3.81,P<0.05), the non first-episode subgroup (SMD=1.26,95%CI:0.60~1.93,P<0.05)]. Conclusion There is a good correlation between depression and the serum IL-6 concentration. Due to the small number of studies and heterogeneity in different studies, the present meta-analysis has not yet confirmed the quantitative correla-tion between IL-6 and depression.
