OBJECTIVE:To study the effects of indometacin on apootosis and proliferation of cervical cancer Hela cell. METH-ODS:Hela cell was cultured in vitro as study object,and cultured with 0(blank control),200,400,600,800 and 1 000 μmol/L indometacin for 24,48 and 72 h. The inhibitory rate of indometacin to the proliferation of Hela cells was detected by MTT assay. After treated with 0(blank control),400,600 and 800 μmol/L indometacin for 24 h,the change of cellular morphology was ob-served by invert microscope;cell cycle phase and apoptosis were analyzed by flow cytometry. RESUITS:Indometacin of 600, 800,1 000μmol/L could inhibit the proliferation of Hela cell,which was positively correlated to drug concentration and time. Com-pared with blank control,indometacin could induce that Hela cell transformed from polygonous to round in appearance,and result-ed in cell apoptosis and necrosis;the proportion of cells at G0/G1 phase increased,while the proportion of cells at S phase reduced;the apoptotic rate of cells raised. CONCLUSIONS:Indometacin could inhibit the proliferation of Hela cell,block cell cycle at G0/G1 phase and induce apoptosis.

Bronchopulmonary dysplasia( BPD) is a chronic lung disease that commonly occurs in pre-term. Since the 1980s,with the advances in perinatal care,survival rate of preterm has been raised,while BPD continues to be a significant cause of morbidity and mortality for premature infants. However,the treatment effect of BPD is unsatisfactory. It is urgent to search for innovative ways to reduce the respiratory injury that caused by BPD as well as to improve the quality of life. In recent years,mesenchymal stem cells′( MSC) research has pro-vided a new way for the treatment of BPD. This review primarily summarizes the current status of the MSC ther-apies and its possible mechanism on BPD.

Objective To investigate the indications,approaches,and essentials of cranio-orbital surgeries for orbital apextumors.Methods The clinical data of 48 patients with orbital apextumors treated by refined transcranial orbitotomy through superolateral approach were analyzed retrospectively,34 tumors were excised with orbitoptenonal approach,while 14 tumors were excised with orbltotrontal approach,orbitozygomatic approach,or zygomatic-ptefional approach.Results Of the 48 orbital apextumors,33 cases were totally resected,7 cases were subtotally resected,and 6 cases were partly resected.The other 2 cases were taken biopsies.The optic functions improved or retained in 40 cases,7 cases suffered from eye-moving disfunction or visual-acuity declines,and 1 case suffered from hemiparalysis.Conclusions Tumors in the posterior and apex part of the orbit,or tumors extended from the orbit to the cranial,can be well treated through transcranial approach.Appropriate methods may help to bring maximum convenience to exposure and excision of the lesion,and to conserve the functions.Unnecessary injuries could be avoided as well.

Objective To investigate the subthreshold depression for long-term survivors after breast cancer surgery and its effect on their quality of life (QOL). Methods The self-made general questionnaire, Centre for Epidemiological Studies Depression Scale (CES- D), Hamihon Rating Scale for Depression and Functional Assessment of Cancer Therapy- Breast were used to investigate the subthreshold depression and its effect on their QOL for 210 long-term survivors after breast cancer surgery. The difference in general conditions and score of QOL between the subthreshold depression and non-subthreshold depression groups was also compared. Results The subthreshold depression with incidence rate of 46.67%(98/210) was observed for the log-term survivors after breast cancer surgery in this study. The results indicated that the age (≤50) (OR=5.627, 2.662,P<0.01), marriage (unmarried, divorced or widowed) (OR=5.087, P<0.01), employment (unemployed, sick leave or retired) (OR=2.077,P<0.05) and low income (<3000 RMB/month) (OR=3.375,P<0.01) were the key factors that led to the occurrence of subthreshold depression. The score of QOL for the subthreshold depression group were lower than those of the non-subthreshold depression group (t=-6.653--2.926,P<0.01), and had a significantly negative correlation with score of depression and QOL (β=-0.362--0.132). Conclusions A high incidence rate of subthreshold depression for long-term survivors after breast cancer surgery was observed. The incidence rate of subthreshold depression increased for the patients with younger age, low income,unmarried or unemployment. Due to their low QOL, attentions should be paid to the early detection and early prevention for the long-term survivors with subthreshold depression after breast cancer surgery.

OBJECTIVE To investigate the effect of bevacizumab ,an anti-human vascular endothelial growth factor monoclonal antibody,on pulmonary dissemination of colorectal cancer. METHODS A metastatic colorectal cancer mouse model was established. Mice were randomly divided into two groups(n=8). The mice in experimental group were administered ip with bevacizumab at the dosage of 5 mg · kg-1,and those in control group were given isotype IgG at the same dosage. The antibodies were administered on 2 d before initiation of model establishment and 2 d after that,then once every 5 d for 4 weeks,for a total of 7 times. Liver and lung metastases were determined by histopathological examination. The chemokine receptor C-X-C receptor 4(CXCR4)and its ligand C-X-C ligand 12(CXCL12)mRNA expression in the lung were detected by quantitative RT-PCR. Human colon cancer cells HCT116 were treated with bevacizumab(5 mg·L-1)for 24 h. The expression levels of vascular endothelial growth factor receptor 1(VEGFR1)and CXCR4/7 protein as well as CXCR3/4/7 mRNA were examined by Western blotting and quantitative RT-PCR respectively. RESULTS The number of mice(2/8) with liver metastases was reduced,while the number of mice(8/8) with lung metastases increased in experimental group compared with isotype IgG-treated group(6/8 and 2/8 respectively,P<0.05). The mRNA expression level of CXCR4 and CXCL12 in lung tissue was significantly up-regulated in bevacizumab-treated group com?pared with control group(P<0.05). The mRNA and protein expression level of CXCR4 and CXCR7 was dramatically increased in HCT116 cells treated with bevacizumab(P<0.05). CONCLUSION Bevacizumab can potentially promote lung metastases of colorectal cancer,which may be related to up-regulation of CXCR4 and CXCL12 expression.

Objective To investigate effects of capsaicin on proliferation,migration and invasion of human large cell carcinoma NCI-H460 and discuss the possible mechanisms by which capsaicin inhibits non-small cell lung cancer. Methods NCI-H460 cells were cultured in vitro and treated with capsaicin at various concentrations. Colony formation assay,wound healing assay,and transwell chamber invasion assay were used to detect the effects of capsaicin on proliferation,migration and invasion of NCI-H460 cells. Western blotting was used to detect the protein expression of E-cadherin,N-cadherin,Vimentin and Snail. Results The rate of colony formation of 100,200,300 μmol.L-1 of capsaicin were (91.17±24.38)%,(43.22±12.91)% and (15.71±4.26)%,respectively,the control group was (99.53±21.25)%.the rate of migration of NCI-H460 cells of 25,50, 100 μmol.L-1 of capsaicin were (85.83±17.43)%,(37.92±10.16)% and(21.08±6.39)%,respectively,the control group was (93.04±20.23)%.The number of invasion of NCI-H460 cells of 25,50,100 μmol.L-1 of capsaicin were (99±18.2),(75± 17.9) and( 52 ± 14. 1 ) , respectively, the control group was ( 107 ± 20. 4 ) . The middle and high-dose capsaicincould inhibit proliferation,migration and invasion of NCI-H460 cells ( P<0.05) ,and E-cadherin expression level was significantly up-regulated and N-cadherin, Vimentin, Snail expression level was significantly down-regulated ( P<0. 05 ) . Conclusion Capsaicin can inhibit proliferation,migration and invasion of NCI-H460 cells,the mechanism may be related to up-regulation of E-cadherin and down-regulation of N-cadherin,Vimentin and Snail expression levels.

To investigate the therapeutic effect of peroxiredoxin-6(PRDX6)on ultraviolet-induced corneal injury in rats and explore the mechanism.The rat model of corneal injury was established by exposing to ultravio-let.Male wister rats were randomly divided into control groups,dexamethasone (DXM)groups and PRDX6 groups,the rats were administered four times a day and for 12 days.The corneal opacity was observed with a slit-lamp microscope.Histopathologic changes were observed with light microscopy.The content of corneal malonalde-hyde(MDA)was determined by thiobarbituric acid test and the total antioxidative capacity(TAOC)was detected by chemical colorimetric test.P38 MAPK signal pathway was detected with the method of Western blot and the gene expression of cytokines were measured by RT-PCR method.Compared with the control group,PRDX6 treat-ment significantly reduced corneal opacity,improved corneal pathology injury,decreased the MDA content and in-creased the TAOC.In the PRDX6 group the level of phosphorylated p38 protein was significantly lower than that in the control group.The gene expression of cytokine were different between control and PRDX6 groups(P <0.05).PRDX6 showed therapeutic effect in the rat model of ultraviolet-induced corneal injury.This maybe be concerned with that it could alleviated the oxidative damage,suppressed p38 MAPK phosphorylation and regulate the gene expression of cytokine.
