Purpose To measure the nuclear morphological parameters of breast cancer to study the relationship between nuclear mor-phological parameters and ER, PR, HER-2 expression, and clinicopathologic features of breast carcinoma. Methods 388 cases of breast cancer specimens were collected and molecular classification was made according to ER, PR and HER-2 expression. the nucleus parameters were measured by image analysis software after HE staining. The difference among groups was statistically analysed, and follow-up was done by phone or by hospitalization. Results Among the 4 groups of breast cancer case, the differences of circle diame-ter, area and perimeter edges of the nucleus were statistically significant (P<0.05). Nuclear morphometric quantitation between ER+/PR+ patients and ER-/PR- patients was statistically significantly differentice (P<0.05). The majority of patients with ER-/PR- were histological gradeⅢand poor survival rate (P<0.05). The disease-free survival in Luminal A type was higher than that of Basal-like type (P<0.05), and its overall survival was higher than HER-2 over-expression (P<0. 05) and Basal-like type (P<0.05) . Conclusion The nucleus morphological quantitation in breast cancer is of significant difference, which has certain reference value in its molecular typing. The result of ER, PR and HER-2 expression, combined with nuclear morphology measurement, are meaningful to the treatment and assessment of prognosis.

Objective To prepare a targeted antitumor drug delivery system using large-inner-diameter multi-walled carbon nanotubes (LID-MWCNTs) for sustained release and to study its performance. Methods LID-MWCNTs were puri?fied and oxidized,then use nanocarriers and USTs as homologous blockers. Folic acid and fluorescent labels were conjugat?ed onto the external surfaces of nanocarriers. CDDP (cisplatin) was encapsulated and ultrashort tubes (USTs) were employed to block the drug entry/exit paths. The microstructure of resulted drug delivery system (DDS) was observed, while drug load?ing efficiency and drug release profile in vitro were determined. The tumor-targeting property and cytotoxicity of DDS were also assessed. Results LID-MWCNT based sustained release targeted drug delivery system was established. Drug loading efficiency of CDDP@UST-FA-LID-MWCNTs was as high as 70.97%. A typical biphasic sustained release pattern was dem?onstrated, and the accumulating release time was 18 h. DDS exhibited a certain kind of tumor-targeting property, and inhibit?ed proliferation of tumor cells in a dose-dependent manner. Conclusion CDDP@UST-FA-LID-MWCNT drug delivery system exhibited an improved drug loading efficiency and a sustained drug release profile. It could specifically target the tu?mor cells and had a significant antitumor effect.

Objective To explore the clinical significance of detecting hand-foot-and-mouth disease (HFMD) children's cardiac enzymes and neuron-specific enolase (NSE).Methods One hundred and fiftytwo HFMD children were selected as observation group,and 56 cases of healthy children were selected as control group.Cardiac enzymes and NSE levels were compared between two groups.Results The levels of aspartic transaminase(AST),creatine kinase(CK),creatine kinase isozyme-MB(CK-MB),lactate dehydrogenase (LDH),alpha-hydroxybutyric dehydrogenase (α-HBDH),and NSE in observation group were (40.4 ± 14.8)U/L,(109.9 ± 87.5) U/L,(47.0 ± 29.4) U/L,(316.9 ± 119.2) U/L,(256.2 ± 96.1) U/L,(30.9 ± 18.2) μ g/L,and in control group were (24.5 ± 9.2) U/L,(77.4 ± 32.5) U/L,(15.4 ± 7.4) U/L,(134.0 ± 34.4) U/L,(131.1 ± 37.7)U/L,(9.8 ± 4.6) μ g/L.The differences between two groups were statistical significance(P ＜ 0.01).Conclusion The heart and nervous system lesions of HFMD children can be found through detecting cardiac enzymes and NSE early,which provide evidence for early diagnosis and treatment.

OBJECTIVE To explore the role of gecko crude peptides (GCPs) in the proliferation, apoptosis, migration and lymphangiogenesis of human hepatocellular carcinoma cells (HepG2) and human lymphaticendothelial cells (HLECs) in vitro. METHODS The 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay was used to evaluate the anti- proliferative effect of GCPs and siRNA-VEGF-C on HepG2 cells, Hoechst 33258 staining and flow cytometry were performed to analyze cycle and apoptosis. The migration and invasion ability of cells were assayed by transwell chamber experiment and wound-healing assay. The protein and mRNA expressions of vascular endo?thelial growth factor-C (VEGF-C) and CXC chemokine receptor-4 (CXCR4) were detected by q-PCR, immunofluorescence, Western blot. The protein expressions of the extracellular signal regulated kinase (ERKI/2), c-Jun N-terminal kinase (JNK), p38-mitogen activated protein kinases (p38 MAPK), serine/threonine kinase (Akt) and phosphatidylinositol- 3- kinase (PI3K) were detected by western blot. The anti-lymphangiogenesis effect of GCPs on the HLECs was analyzed using an in vitro tube-formation assay. The protein and mRNA expressions of vascular endothelial growth factor receptor-3 (VEGFR-3) and stromal cell-derived factor-1 (SDF-1) were detected by q-PCR, Western blot. RESULTS GCPs and siRNA-VEGF-C inhibited HepG2 proliferation, invasion and migration, and the most obvious inhibitory effect was both synergistic effects. Thus, GCPs suppressed HLECs proliferation, migration and tube-like structure formationin a dose- dependent manner, and had inhibitory effect of tumor- induced lymphangiogenesis in vitro. Additionally, we found that GCPs and siRNA- VEGF- C decreased the expressions of MMP-2, MMP-9, VEGF-C, CXCR4, phospho-ERK1/2, phospho-P38, phospho-JNK and PI3K in HepG2 cells. Moreover, GCPs had a dose-dependent depressive effecton the expressions of VEGFR- 3, SDF- 1 in HLECs. CONCLUSION The low expression of VEGF- C mediated by siRNA-VEGF-C and GCPs inhibit tumor proliferation, invasion and migrationby suppressing the MAPK signaling pathway through reduced levels of VEGF-C, and GCPs inhibit tumor lymphangiogenesis by suppressing the CXCR4/SDF-1 signaling pathway through suppressed VEGF-C/VEGFR-3.
