OBJECTIVETo study the expression of lipoprotein related genes in subchondral bone of early experimental os-teoarthritis, which may play an important role in the pathogenesis of osteoarthritis.

METHODSAnimals are equally divided into two groups: experimental group and control group, both of which contain fifteen rats of similar weight. The right knee joints of experimental group underwent surgery,which involved in both medial collateral ligament(MCL) transaction and medial meniscectomy, while the control group was only carried out with a sham operation. Rats were killed at 1, 2 and 4 weeks postsurgery to obtain the right knee joints. Total RNA of the subchondral bone was extracted,and then hybridized to Agilent Whole Rat Genome Microarray. Differentially expressed genes analysis was used to study the chemokine signaling pathway.

RESULTSApoa5 expression was down-regulated at 1, 2 weeks post-surgery, Apoc2 expression was up-regulated at 1 week after surgery, Apol3 expression was up-regulated at 1 and down-regulated at 4 weeks post-surgery, Lrp1 expression was down-regulated at 1, 2 weeks after surgery. Lrp5 was down-regulated at 2 weeks after surgery. Gpihbp1, Lpl, Tfpi and Vldlr were up-regulated at 1 weeks after surgery. Lrpap1 and RGD1309808 were down-regulated at 4 weeks after surgery.

CONCLUSIONDysregulation of lipoprotein related genes plays an important role in pathogenesis of early experimental osteoarthritis.

Objective To investigate the effect of acupuncture at Zusanli, Sanyinjiao and Danzhong on mammary estrogen receptor (ER) and progesterone receptor (PR) expressions in rats with dimethylbenzanthracine (DMBA)-induced mammary cancer. Methods One hundred and twenty female SD rats aged 6-8 weeks were randomized into a model group of 60 rats and a blank group of 30 rats. The model group received an oral gavage of DMBA for model making. The blank group received an oral gavage of equal volume of sesame oil. At 15 weeks after model making, the model group of rats was randomized into treatment and control groups. The treatment group received acupuncture at Zusanli, Sanyinjiao and Danzhong, and the control and blank groups, only the same grasp and release. After the completion of acupuncture treatment (twenty-seventh week), abdominal venous blood was taken and serum tumor markers were determined by electrochemiluminescence immunoassay. Tumor masses were counted and their shapes were recorded. The mass was taken and its height, maximum diameter and vertical diameter were measured using a 1 mm precision vernier caliper. Pathological changes in tumor tissues, and ER and PR positive areas and mean optical densities were observed under an Olympus optical microscope.Results There were statistically significant post-treatment differences in the average number and volume of mammary tumors between the treatment group and the control or blank group (P<0.01,P<0.05) and between the control and blank groups (P<0.01). There were statistically significant post-treatment differences in the concentrations of various tumor markers (CA724, CA125, CA199, AEP, CA15-3, CEA and CA50) between the treatment or control group and the blank group (P<0.01,P<0.05) and between the control and blank groups (P<0.01). There was a statistically significant post-treatment difference in CA15-3 concentration between the treatment and control groups (P<0.01). There were statistically significant post-treatment differences in ER and PR positive areas and mean optical densities between the treatment group and the control or blank group (P<0.01) and between the control and blank groups (P<0.01).Conclusions Acupuncture can reduce the occurrence of rat DMBA-induced mammary tumor (including the number and volumes of the tumors). The mechanism of its action may be related to decreasing the concentrations of tumor markers CA724, CA125, CA199, CA15-3, AEP, CEA and CA50 and especially to decreasing CA15-3 concentration, and ER and PR positive areas and mean optical densities.

Objective To investigate the effect of BDNF on cell injuries, cell apoptosis especially, induced by 25-35 segment of β-amyloid protein (Aβ25-35) at condensed state in PC12 cells.Methods The viability of PC12 cells, the apoptosis of PC12 cells and the expressions of Bax and Bcl-2 were detected by MTT, Annexin V-PI staining and Western blotting, respectively. Trk B receptor inhibitor K252a (200 nmol/l) was employed to observe the mechanism of 50 ng/ml BDNF on Aβ25-35 (20 μmol/L)-induced cell injury. Results BDNF (50 ng/ml) could significantly prevent the decrease of cell viability and cell apoptosis, and the increase of Bax expression and the decrease of Bcl-2 expression induced by 20 μmol/L Aβ25-35, and prevent the increase of up-regulation of Bax/Bcl-2 ratio; and these effects were blocked by K252a (200 nmol/1). Conclusion BDNF can prevent Aβ25-35-induced cell injury, cell apoptosis especially, by binding to its specific receptor Trk B.

OBJECTIVETo investigate the effects of FTY720, a new immunosuppressive agent, on apoptosis and autophagy in multiple myeloma(MM) cell line U266 and to clarify its molecular mechanism.

METHODSU266 cells were treated with 0, 2.5, 5.0, 10.0 and 20.0 µmol/L FTY720 for 24 hours, and the cell viability was assayed by CCK-8 method. Then U266 cells were treated with 20.0 µmol/L FTY720 for 0, 2, 6 and 24 hours, the cell viability was tested. The apoptotic rates induced by different doses and time points of FTY720 were tested by flow cytometry separately. The expression of LC3B was detected by Western blot after U266 cells treated with different doses of FTY720 to see autophagy. U266 cells were treated with FTY720 ± Bafilomycin A1, an inhibitor of autophagy, for 24 hours, then the cell viability and apoptotic rates were tested. Meanwhile the expression of survivin, anti-apoptotic factors, were tested by Western blot.

RESULTSThe cell viability and the apoptotic rates were inhibited significantly by FTY720 (P < 0.05) in time-dependent and dose-dependent manner. The expression of LC3B-II increased significantly in a dose-dependent manner, it indicated that the autophagy was induced by FTY720. Bafilomycin A1 could rescue the cell viability and apoptotic rates in U266 cells treated with FTY720, and it could also rescue the expression of survivin decreased by FTY720.

CONCLUSIONSFTY720 can cause apoptosis and autophagy of U266 cells. The autophagy promote the apoptosis, which maybe due to the degradation of anti-apoptotic factors such as survivin or their upstream factors in lysosomes through autophagy.

This study was aimed to investigate the influence of TIEG1 on apoptosis of HL-60 cells and the expression of Bcl-2/Bax. Different concentration of TIEG1 were used to treat HL-60 cells, the cell growth inhibition rate was detected by MTT method. After treating HL-60 cells with 12.03 ng/ml TIEG1, cell apoptosis was detected with flow cytometry. Bcl-2 and Bax was detected with RT-PCR. The results showed that TIEG1 had inhibitory effect on HL-60 cell proliferation, and in time-and dose-dependent manners. The more obvious inhibitory effect was observed in HL-60 cells treated with TIEG1 of 12.03 ng/ml. During the course of cell apoptosis, Bax expression increased, but Bcl-2 expression decreased (P < 0.05). It is concluded that TIEG1 inhibits HL-60 cell proliferation and induces apoptosis in time and dose-dependent manners. During the course of HL-60 cells apoptosis induced by TIEG1, Bcl-2/Bax are associated with HL-60 cell apoptosis induced by TIEG1.

This study was aimed to explore whether bortezomib can sensitize HL-60 cells to TNF-related apoptosis-inducing ligand (TRAIL) and to investigate its possible mechanism. The HL-60 cells were treated by different concentrations of TRAIL combined with subtoxic concentration of bortezomib. The proliferative inhibition of treated HL-60 cell was analysed by MTT assay. The cell apoptosis was determined by flow cytometry with Annexin V/PI double staining and the expression of caspase-8 was detected by Western blot. The results showed that the subtoxic concentration of bortezomib combined with 10 ng/ml of TRAIL enhanced apoptosis of HL-60 cells, as compared with TRAIL used alone; the expression of caspase-8 increased correspondingly. It is concluded that subtoxic concentration of bortezomib can sensitize HL-60 cells to TRAIL and its mechanism may be related to upregulation of caspase-8 expression.

Objective To observe the effect of stage-based acupuncture-moxibustion therapy on the endometrial thickness in patients suffering from repeated implantation failure in IVF-ET (in vitro fertilization and embryo transfer). Method Seventy-two patients suffering from repeated implantation failure in IVF-ET were randomized into two groups. Thirty-six cases in the treatment group were intervened by stage-based acupuncture-moxibustion therapy plus oral administration of Estradiol valerate tablets; the other 36 cases in the control group were prescribed with oral administration of Estradiol valerate tablets alone. The implantation result of IVF-ET was analyzed 3 cycles later. The endometrial thickness was compared before and after the intervention. Result The endometrial thickness of the non-pregnant women increased after the treatment in both groups (P<0.05), and the increase in the treatment group was more significant than that in the control group (P<0.05). The clinical pregnancy rate in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion Stage-based acupuncture-moxibustion therapy can improve the endometrial thickness, promote the growth of endometrium, benefit the implantation of embryo, and enhance the clinical pregnancy rate.
