Objective To study the expression of insulin like growth factor binding proteins 3 (IGFBP-3) during inhi-bition of resveratrol (Res) on cell proliferation. Methods The inhibitory effect of Res on BGC-823 cells was determined by MTT method; Real-time qRT-PCR and western blot were applied to detect the expression of IGFBP-3 in Res-treated BGC-823 cells. In addition, cytometry was used to determine the proliferation and apoptosis of Res-treated BGC-823 after knockdown of IG-FBP-3 by siRNA. Results Upon Res (20,40, 80 and 160 μmol · L-1 ) treatment,the viability of BGC-823 cells was (82. 35±10. 65)% ,(74. 30±12. 36)% ,(62. 80±14. 66)% and (50. 75±11. 14)% , respectively. The mRNA and protein ex-pression of IGFBP-3 elevated as high as 2. 96-fold compared to the control group (P<0. 05). The cell viability of BGC-823 cells with IGFBP-3 knockdown was significantly higher than that of the wild type ( P < 0. 05 ) only at high Res concentration (160 μmol·L-1 ). Meanwhile,IGFBP-3 knockdown led to a significant decrease on cell apoptotic rate by Res (160 μmol·L-1 ) [(20. 13±9. 12)% vs (35. 48±11. 12)% ,P<0. 05)]. Conclusion Res can inhibit BGC-823 cell proliferation and promote cell apoptosis, the underlying mechanism of which may be related to the overexpression of IGFBP-3 in BGC-823 cells.

The study investigated the effects of heat shock protein 70 (HSP70) antisense oligonucleotide (ASODN) on the proliferation and apoptosis of a human hepatocellular carcinoma cell line (SMMC-7721 cells) in vitro. HSP70 oligonucleotide was transfected into SMMC-7721 cells by the mediation of Sofast transfection reagent. Inhibition rate of SMMC-7721 cells was determined by using MTT method. Apoptosis rate and cell cycle distribution were measured by flow cytometry. Immunocytochemistry staining was used to observe the expression of HSP70, Bcl-2 and Bax. The results showed that HSP70 ASODN at various concentrations could significantly inhibit the growth of SMMC-7721 cells, and the inhibition effect peaked 48 h after transfection with 400-nmol/L HSP70 ASODN. Cytometric analysis showed the apoptotic rate was increased in a dose- and time-dependent manner in the HSP70 ASODN-treated cells. The percentage of cells in the G(2)/M and S phases was significantly decreased and that in the G(0)/G(1) phase increased as the HSP70 ASODN concentration was elevated and the exposure time prolonged. Immunocytochemistry showed that treatment of SMMC-7721 cells with HSP70 ASODN resulted in decreased expressions of HSP70 and Bcl-2 proteins, and an increased expression of Bax protein. It was concluded that the HSP70 ASODN can inhibit the growth of the SMMC-7721 cells and increase cell apoptosis by down-regulating the expression of HSP70. HSP70 ASODN holds promise for the treatment of hepatocellular carcinoma.

BACKGROUND:Estrogen signaling pathway for interaction between aromatase and estrogen-related receptor may exist in bone marrow mesenchymal stem cel s, which is used for regulating biological activity of bone marrow mesenchymal stem cel s. OBJECTIVE:To observe the expression of aromatase and estrogen-related receptors in adult bone marrow mesenchymal stem cel s during osteogenic differentiation. METHODS:Bone marrow mesenchymal stem cel s were respectively cultured in low-glucose DMEM medium (control group) and osteogenic induction medium (induction group). Cel proliferation and calcium deposition were determined by MTT assay and alizarin red staining, respectively. The expression of aromatase, estrogen receptorα, estrogen receptorβ, and estrogen-related receptorαduring osteogenic differentiation were determined by real-time PCR and western blot analysis. Estradiol levels in supernatants and lysates were detected by ELISA method. RESULTS AND CONCLUSION:In the induction group, the proliferation ability of bone marrow mesenchymal stem cel s was the strongest at 72 hours of culture;while there were a great amount of calcium nodules formed at 21 days of culture. Results from PCR and western blot assay showed that the expression of aromatase and estrogen receptorαwas improved in the induction group, but the expression of estrogen-related receptorαwas inhibited. There was no difference in the expression of estrogen receptorβbetween the two groups. ELISA results indicated that the level of estradiol in the supernatant of induction group was the highest. These findings indicate that aromatase, estrogen receptorα, estrogen receptorβand estrogen-related receptorαare al involved in osteogenesis of bone marrow mesenchymal stem cel s. Moreover, estradiol can be synthesized and secreted in bone marrow mesenchymal stem cel s, and most likely, promote the osteogenic differentiation of bone marrow mesenchymal stem cel s by related receptor pathway.

Objective To explore the effect of improved surgical method of intramedullary fibular allograft together with cannulated screw fixation combined with blood-activating and stasis-resolving Chinese medicine on the quality of life (QOL) of young and middle-aged fresh femoral neck fractures at intermediate stage. Methods A retrospective analysis was carried out in the articular orthopedics department of the First Affiliated Hospital of Guangzhou University of Chinese Medicine. The study involved 80 cases of young and middle-aged fresh femoral neck fractures receiving intramedullary fibular allograft together with cannulated screw fixation, and 50 qualified cases receiving cannulated screw fixation alone ( control group) . After the operation, all of the patients were given oral use of blood-activating and stasis-resolving Chinese medicine. After the last follow-up, Harris hip scoring, SF-36 scoring and radiographic evaluation were performed for the evaluation of clinical efficacy. Results The clinical application of intramedullary fibular allograft together with cannulated screw fixation combined with Chinese medicine was fulfilled in 80 hips of 80 cases. The follow-up period ranged from 48 to 84 months, averaging 62.68 ± 12.43 months. The improved surgical method group had an excellent and good rate of 93.75%, presented excellent-grade Harris scores and SF-36 scores, and had higher QOL scores than the control group (P<0.05) . After treatment, the two groups had statistically significant differences in the scores of SF-36 items of physical function ( PF) , bodily pain ( BP) , mental health ( MH) , vitality ( VT) , and general health ( GH) ( P<0.05 or P<0.01) , and also had significant differences in Harris scoring of pain, function and daily activities as well as the joint range-of-motion ( P<0.05 or P<0.01) . Conclusion The improved surgical method of intramedullary fibular allograft together with cannulated screw fixation combined with blood-activating and stasis-resolving Chinese medicine shows satisfactory therapeutic effect for young and middle-aged fresh femoral neck fractures at intermediate stages, which has the advantages of lower collapse rate after femoral head necrosis, less joint replacement, higher scores of the quality of life and Harris scoring, and better radiographic indicators than cannulated screw fixation alone.
