AIM:To investigate the apoptotic pathway of MCF-7 breast cancer induced by the grub extract in vitro.METHODS:MTT assay was used to determine the effect of the grub extract on proliferation of MCF-7 human breast cancer cell line and cell toxicity.Morphological changes of the apoptosis in cancer cells were observed by HE staining through invert microscope,light microscope,AO/EB double fluorescent staining under fluorescent microscope.FCM was used to assay the change of apoptotic rate.The expression of Bcl-2,Fas,caspase-9,caspase-3 in apoptotic pathway was detected with immunocytochemical method before and after exposure to the grub extract,and the effect of that on apoptotic pathway was explored.RESULTS:(1)The MTT test showed that the growth of MCF-7 human breast cancer cell line was significantly inhibited by the grub extract in dose and time dependent manners.The inhibitory rate in exposure group was significantly different from that in control group(P

AIM: To analyze the effect of human amniotic homogenate extract on corneal neovascularization after corneal alkali burn in the process of pigment epithelium derived factor (PEDF) and vascular endothelial growth factor (VEGF) expression and the effect of corneal neovascularization.METHODS: Totally 32 patients with corneal alkali burn were selected from June 2015 to June 2016 in Foshan,and were randomly divided into Group A and Group B,with a total of 37 eyes.Group A of 17 cases,with a total of 19 eyes,were treated with 40mg/L human amniotic homogenate extract;Group B (n=15),and 18 eyes,treated with 3g/L prednisolone eye drops.In the treatment of 1,4,7,14,21 and 28d at different time points,we observed the growth of corneal neovascularization,and detected the expression of PEDF and VEGF during angiogenesis.RESULTS: Group A of patients in the use of human amniotic homogenate extract after the treatment,the expression level of PEDF was significantly higher than that in Group B(P=0.001),after 28d treatment,the expression level of PEDF reached 0.721±0.314.While patients in Group B the expression level of PEDF was only 0.538±0.253.Two groups had significant difference between the expression level of PEDF (P<0.05).The expression level of VEGF in Group A was lower than in Group B at different time points in the test.After the treatment of 28d patients in the Group A,the expression level of VEGF was 0.152±0.020,in Group B the expression level of VEGF was0.302±0.031.Two groups of patients with VEGF expression level between the differences were statistically significant (P<0.05).The patients number in Group A with corneal neovascularization was significantly lower than that in Group B,the difference was statistically significant (P<0.05).CONCLUSION: Human amniotic homogenate extract can increase the expression of PEDF in corneal neovascularization after corneal alkali burn,inhibit the expression of VEGF and the proliferation of corneal neovascularization.

Objective To evaluate the number and function of peripheral Vγ2Vδ2+T lymphocytes during Mycobacterium tuberculosis(MTB)infection in human immunodeficiency virus (HIV)infected individuals.Methods Seventy-six HIV/acquired immune deficiency syndrome(AIDS) patients co-infected with MTB were divided into active tuberculosis(TB)group(HIV+TB)and latent TB group(HIV+LTB).T cell subsets of peripheral blood lymphocytes were analysed by flow cytometry.Stimulated by protein purified derivative(PPD)and hydroxymethylbutenyl diphosphate (HMBPP),specific interferon(IFN)-γ producing T cells were detected using enzyme-linked immunospot(ELISPOT)and intracellular cytokine staining(ICS).Data were analyzed by t test.Results The absolute number of CD3'T cells and DroDortion of V72VB2'T cells in CD3+T cells in HIV+TB group were both significantly lower than those in HIV+LTB group(t=-3.67,P<0.01;t=-2.06,P<0.05).PPD-specific IFN-y-producing T cells and percentage of PPD-specific CD4+Tcells in CD3+T cells in HIV+LTB group were both similar with those in HIV+TB group.While HMBPP-specific IFN-γ-producing T cells and percentage of HMBPP-specific Vγ2Vδ2+T cells in CD3+Tcells in HIV+LTB group were both higher than those in HIV+TB group(t=2.71 and t=3.003,respectively;both P<0.0 1).Conclusion The number and function of Vγ2Vδ2+T cells were impaired in HIV/AIDS patients coinfected with active MTB infection,which indicates that Vγ2Vδ2+T cells may be the key immune cells against MTB in individuals with impaired CD4+T cells.

To investigate the anticancer effects of ring C in 18β-glycyrrhetinic acid (GA), a series of GA derivatives featured with 9(11)-ene moiety in ring C were designed and synthesized. The structures were confirmed by IR, LC-MS and 1H NMR. Their inhibitory effects towards human prostate cancer PC-3 and leukemia HL-60 cell lines were determined. Most of the derivatives displayed stronger antiproliferative activities than GA. Particularly, compound 14 showed promising anticancer activity with the GI50 values of 4.48 µmol · L(-1) and 1.2 µmol · L(-1) against PC-3 and HL-60 cells respectively, which is worth further study.

Objective To investigate the role of contrast enhanced ultrasound (CEUS) in evaluating and guiding radiofrequency ablation (RFA) of hepatocellular carcinoma (HCC) and its feeding vessels. Methods From January 2006 to June 2007, 71 patients with 75 hypervascular HCC in Peking University Cancer Hospital who underwent RFA were included in the study. The diagnosis was conifrmed by ultrasound guided biopsy for all patients. These patients were not suitable for transcatheter arterial chemoembolization (TACE) or had poor responds to TACE. They were divided into two groups, which included group percutaneous artery ablation (PAA) combining RFA and group RFA. There were 38 patients with 39 HCC in group PAA combining RFA and CEUS were used to identify the range of HCC inifltration. Firstly, PAA of the feeding vessels was conducted under the guidance of color doplor lfow imaging (CDFI). Then CEUS was performed to evaluate HCC perfusion after blocking the feeding vessels. Finally, the rest of the tumor was ablated by RFA. In group RFA, there were 33 patients with 36 HCC, who did not undertake PAA before RFA. Generally, the RFA was planned based on tumor size and location, and the ablation started with deep part of HCC or portion close to nearby organs. Contrast CT was used as a post-RFA imaging for follow-up at 1, 3 and 6 months post-RFA. T test was used to compare the difference in focal lesions number between two groups, andχ2 tests were used to compare the difference in necrosis rate between two groups after treatment. Results In group PAA combining RFA, post-PAA CEUS showed intratumor perfusion decreased more than 70%in 31 HCC (79.5%, 31/39). Of them, 13 HCC (33.3%, 13/39) showed complete perfusion defect with clear margin, called“solar eclipse sign”. The rest 8 HCC (20.5%, 8/39) showed 40%-70%of perfusion defect. In group PAA combining RFA, CDFI showed 35 (83.3%, 35/42) feeding vessels were blocked, and 3 vessels (7.1%, 3/42) showed signiifcant decreased lfow signal after PAA. There were average 3.18±1.42 ablations per HCC in group PAA combining RFA, and 4.32±1.56 in group RFA. The number of ablations per HCC in group PAA combining RFA was signiifcantly less than group RFA (t=2.524, P=0.015). The tumor necrosis rate at 1 month post-RFA in group PAA (92.3%, 36/39) combining RFA was signiifcantly higher than that of group RFA (66.7%, 24/35) (χ2=8.264, P=0.001). Conclusions With CEUS, PAA can effectively block the feeding vessels of HCC, enhance ablated necrosis in the tumor and signiifcantly increase necrosis rate post-RFA for large hypervascular HCC. CEUS-assisted PAA can improve efifciency of RFA with less ablation number and better result.
