Urine provides an alternative to blood plasma as a potential source of disease biomarkers. Exosomes was separated by ultracentrifuge at 200000 g in normal persons and non-small cell lung cancer (NSCLC) patients′ urine. For proteomic analysis of urinary exosome, 1D sodium dodecylsulfonate-polyacrylate gel electrophoresis(SDS-PAGE) was carries out and cut the gel 31 kDa-20 kDa bands in normal group and disease group′s. These gel blocks were subjected to in-gel trypsinization, and the extracted peptides were analyzed HPLC-CHIP-MS/MS. Approximately 24 unique proteins were identified in the UniProtKB/SWISS-PORT. The difference expression proteins were found in urinary exosome from NSCLC patients, including three fragment of the immunoglobulin kappa, two kinds of Ras related proteins, glutathione S-transferase A2, serum amyloid P-component precursor and phosphatidylethanolamine-binding protein 1.

The study of the anti-tumor drugs with effect of killing tumor cells, low toxicity and safety is important for cancer medicine. The silver nanoparticles(AgNP)synthesized by plant extracts have strong anti-tumor activity. The class of drugs is stable, with good curative effect and fewer side effects, which provide an important way for tumor therapy. In this paper, the recent anti-tumor studies of silver nanoparticles synthesized by active components extracted from different parts of plants are reviewed in order to provide theoretical basis for clinical antitumor applications.
8. Meta-analysis of bone metabolism indicators in patients with primary osteoporosis under different forms of exercises
Chinese Journal of Tissue Engineering Research 2020;24(17):2782-2788
BACKGROUND: Physical exercise can significantly reduce bone mass loss, relieve pain and improve bone metabolism in osteoporosis patients, but there is no evidence-based evidence. OBJECTIVE: To investigate the effect of different physical exercises on the treatment of primary osteoporosis. METHODS: Randomized controlled clinical trials regarding the therapeutic effect of physical exercise on primary osteoporosis were screened. The physical exercise group was subjected to physical exercise, and the control group had no regular exercise during the test. The main outcome measures included bone mineral density of lumbar spine L2-L4, visual analog scale score, bone metabolism index (osteocalcin, total type 1 procollagen amino terminal peptide, urine pyridinium/creatinine, blood calcium, blood phosphorus). The included outcome indicators were meta-analyzed using the Review Manager 5.3 software. RESULTS AND CONCLUSION: A total of 25 randomized controlled trials were included. Meta-analysis results showed that physical exercise could effectively improve the bone mineral density of L2-L4 segments in primary osteoporosis patients (mean difference=0.06, 95% confidence interval [0.04-0.08], P < 0.000 01, I2=89%). Subgroup analysis results revealed significant differences in the control group and five-animal exercise & Yi-Jin-Jing group, setting-up exercise group, composite exercise group, and incremental exercise group compared with control group (P < 0.05), while there was no significant difference between other exercise groups and control group (P > 0.05). Physical exercise significantly reduced the pain as determined by the visual analog scale in osteoporosis patients (mean difference=-0.93, 95% confidence interval [-1.08 to -0.79], P < 0.000 01, I2=83%). Exercise intervention could improve serum osteocalcin, total type 1 procollagen amino terminal peptide and blood phosphorus levels, and reduce urine pyridinium/creatinine and serum calcium levels. However, there was no significant difference between exercise groups and control group (P > 0.05). The results of Egger’s and Begg’s tests indicated that publication bias of the included studies was at a low level. All these findings indicate that physical exercise has significant interventional effects on bone mineral density and pain in patients with primary osteoporosis.
9. Effects of all-trans retinoic acid combined with gamma radiation on proliferation and apoptosis of esophageal carcinoma TE13 cells
Tumor 2012;32(8):592-598
Objective: To investigate the effects of ATRA (all-trans-retinoicacid) combined with gamma radiation on proliferation and apoptosis of human esophageal carcinoma TE13 cells, and to explore the possible mechanism. Methods: The effect of ATRA on the proliferation of TE13 cells was detected by MTT method. When the cell growth RI (inhibitory rate) reached levels of 25%, 50% and 75%, the TE13 cells were treated with the corresponding inhibitory doses of ATRA combined with 4 Gy gamma radiation. The effects of this combination intervention on cell cycle distribution and apoptosis of TE13 cells were detected by FCM (flow cytometry). The colony-formation ability and cell viability were detected using colony-formation experiment. The expression of cyclinD1 protein was detected by FCM. Results: The inhibitory effect of ATRA on the proliferation of TE13 cells was significant in a dose- and time-dependent manner. The cell growth IRs reached 22.0%, 55.1% and 71.1% at ATRA concentrations of 0.78, 6.25 and 12.5 μmol/L, respectively. The cell viability and colony-formation efficiency were significantly decreased in TE13 cells treated with ATRA in combination with 4 Gy gamma radiation, as compared with TE13 cells receiving administration of ATRA alone. The proliferative ability of TE13 cells was significantly reduced after ATRA treatment in combination with 4 Gy gamma radiation for 24 and 48 h; furthermore, the percentage of the cells arrested at phase G0/G 1 was increased accompanying with a significantly elevated apoptotic rate. Although the combination treatment (0.78 μmol/L ATRA and gamma radiation) had a weak influence on the expression of cyclinD1 protein, which was significantly decreased in other groups (6.25 and 12.5 μmol/L ATRA). Conclusion: ATRA exerts an inhibitory influence on the proliferation of TE13 cells through down-regulating cyclinD1 expression, arresting the cells at phase G0/G1, and inducing apoptosis. A higher-concentration of ATRA combined with gamma radiation can significantly decrease the expression of cyclinD1, promote G0/G1 cell cycle arrest, accelerate apoptosis, and limit the colony formation, but a lower concentration of ATRA combined with gamma radiation exerts a little influence on cyclinD1 expression, although it may accelerate apoptosis and limit the colony-formation at some periods of time after treatment.

10. RNA interference targeting CXCR7 gene inhibits proliferation and migration of colon cancer cell line SW1116
Tumor 2011;31(5):412-416
Objective: To study the effects of chemokine receptor 7 (CXCR 7) gene on the proliferation and migration of human colon cancer cell line SW1116. Methods: After transfection with small interfering RNA (siRNA) targeting CXCR 7, the expressions of CXCR7 mRNA and protein in human colon cancer cell line SW1116 were determined by RT-PCR and Western blotting, respectively. The effects of altered expression of CXCR7 on cell proliferation and migration were measured by CCK-8 cell proliferation assay and Transwell migration assay, respectively. Results: At 24-hour post-transfection, the relative expression level of CXCR7 mRNA in the CXCR7-siRNA transfection group (0.275±0.018) was reduced by (56.6± 3.8)% as compared with that of the blank control group (0.635±0.024). At 48-hours post-transfection, the relative expression CXCR7 protein in the CXCR7-siRNA transfection group was significantly decreased than those in the negative control group and blank control group (P<0.05). The proliferation abilities of SW1116 cells at 48-, 72-, 96- and 120-hour after CXCR7-siRNA transfection were significantly decreased than those in the negative control group and blank control group (P<0.05). The number of SW1116 cells migrating across the polycarbonate membrane in the CXCR7-siRNA transfection group (22.73±2.01) was significantly lower than those in the negative control group (49.20±3.82) and blank control group (54.80± 4.85) (P<0.05). Conclusion: siRNA targeting CXCR 7 gene can inhibit the proliferation and migration of human colon cancer cell line SW1116.
