RESUMEN
This study was to develop a new method for detecting circulating tumor cells (CTCs) with high sensitivity and specificity, therefore to detect the colorectal cancer as early as possible for improving the detection rate of the disease. To this end, we prepared some micro-column structure microchips modified with graphite oxide-streptavidin (GO-SA) on the surface of microchips, further coupled with a broad-spectrum primary antibody (antibody1, Ab1), anti-epithelial cell adhesion molecule (anti-EpCAM) monoclonal antibody to capture CTCs. Besides, carboxylated multi-walled carbon nanotubes (MWCNTs-COOH) were coupled with colorectal cancer related antibody as specific antibody 2 (Ab2) to prepare complex. The sandwich structure consisting of Ab1-CTCs-Ab2 was constructed by the microchip for capturing CTCs. And the electrochemical workstation was used to detect and verify its high sensitivity and specificity. Results showed that the combination of immunosensor and micro-nano technology has greatly improved the detection sensitivity and specificity of the immunosensor. And we also verified the feasibility of the immunosensor for clinical blood sample detection, and successfully recognitized detection and quantization of CTCs in peripheral blood of colorectal cancer patients by this immunosensor. In conclusion, the super sandwich immunosensor based on micro-nano technology provides a new way for the detection of CTCs, which has potential application value in clinical diagnosis and real-time monitoring of disease.

Tumor metastasis depends on the dynamic balance of the actomyosin cytoskeleton. As a key component of actomyosin filaments, non-muscle myosin-IIA disassembly contributes to tumor cell spreading and migration. However, its regulatory mechanism in tumor migration and invasion is poorly understood. Here, we found that oncoprotein hepatitis B X-interacting protein (HBXIP) blocked the myosin-IIA assemble state promoting breast cancer cell migration. Mechanistically, mass spectrometry analysis, co-immunoprecipitation assay and GST-pull down assay proved that HBXIP directly interacted with the assembly-competent domain (ACD) of non-muscle heavy chain myosin-IIA (NMHC-IIA). The interaction was enhanced by NMHC-IIA S1916 phosphorylation via HBXIP-recruited protein kinase PKCβII. Moreover, HBXIP induced the transcription of PRKCB, encoding PKCβII, by coactivating Sp1, and triggered PKCβII kinase activity. Interestingly, RNA sequencing and mouse metastasis model indicated that the anti-hyperlipidemic drug bezafibrate (BZF) suppressed breast cancer metastasis via inhibiting PKCβII-mediated NMHC-IIA phosphorylation in vitro and in vivo. We reveal a novel mechanism by which HBXIP promotes myosin-IIA disassembly via interacting and phosphorylating NMHC-IIA, and BZF can serve as an effective anti-metastatic drug in breast cancer.

RESUMEN
Objective To explore the molecular mechanism of Yishen Huoxue prescription in delaying the development of renal fibrosis by regulating the microRNA-126/vascular endothelial growth factor-Notch (miR-126/VEGF-Notch) signaling pathway. Methods Ninety male Sprague-Dawley (SD) rats were randomly divided into sham operation group (sham group), unilateral ureteral obstruction (UUO) model group, losartan group (50 mg·kg-1·d-1) and high, medium and low doses Yishen Huoxue prescription group (25.2, 12.6, 6.3 mL/kg). Each treatment group began to administer drugs by gavage on the day when UUO modeling was finished until the end of the experiment. Left renal tissues of rats were harvested after 7, 14 and 21 days postoperatively. The pathological changes of renal tissue were observed after hematoxylin and eosin (HE) and Masson staining under the microscope, and the renal fibrosis score was calculated. The mRNA expressions of renal tissues miR-126, VEGFA, vascular endothelial growth factor receptor-2 (VEGFR-2), Notch1 were detected by reverse transcription-polymerase chain reaction (RT-PCR). Results① Pathology results: the kidney tissue of sham group was normal. In UUO model group, renal tubules expanded and inflammatory cells in renal interstitium increased; renal tubulointerstitial fibrosis could be seen 7 days after operation, and the degree of fibrosis was gradually increased with time. The renal fibrosis score at each time point after operation in UUO model group was significantly higher than that in sham group. Compared with UUO model group, each treatment group were improved the degree of renal swelling and atrophy of renal parenchyma; the score of renal fibrosis were significantly decreased in the middle and high doses Yishen Huoxue prescription group and losartan group at the 7th day after operation (1.00±1.00, 0.91±0.58, 1.01±0.58 vs. 2.00±0.00,all P < 0.01); but there was no significant difference between low dose Yishen Huoxue prescription group and UUO model group. ② RT-PCR results: Compared with sham group, the mRNA expressions of miR-126, VEGFA, VEGFR-2 and Notch1 in renal tissues were significantly increased at each time point after operation in UUO model group. Compared with the UUO model group, the mRNA expressions of miR-126, VEGFA, VEGFR-2 and Notch1 in renal tissue of 7 days postoperatively in the middle and high doses Yishen Huoxue prescription group and the losartan group were significantly increased [miR-126(2-ΔΔCt):0.465±0.067, 0.639±0.092, 0.404±0.069 vs. 0.132±0.021; VEGFA(2-ΔΔCt): 0.024±0.005, 0.027±0.007, 0.023±0.006 vs. 0.014±0.006; VEGFR-2(2-ΔΔCt):0.021±0.007, 0.023±0.008, 0.019±0.007 vs. 0.012±0.004; Notch1(2-ΔΔCt):0.017±0.004, 0.020±0.005, 0.018±0.005 vs. 0.007±0.004; all P < 0.05]; compared with the losartan group, the mRNA expressions of each index in the middle and high doses Yishen Huoxue prescription group were increased at all the time points, but there was no significant difference between them (all P > 0.05). There was no significant difference in mRNA expression of each index between low dose Yishen Huoxue prescription group and UUO model group. Conclusions The medium and high doses of Yishen Huoxue prescription can effectively antagonize renal fibrosis. Yishen Huoxue prescription may use up-regulation the signaling pathways of miR-126/VEGF-Notch to mediate renal microvascular newly born, eventually to improve renal microvascular damage and delay the development of renal fibrosis progression.

OBJECTIVE To investigate macrolide resistance and main molecular mechanisms in Mycoplasma pneumoniae. METHODS Thirty two throat swabs from children infected with M. pneumoniae were cultured by modified Hayflick medium. Antibiotic susceptibility test was used to screen the macrolide-resistant M. pneumoniae. The 23S rRNA gene sequences of the strains were determined with polymerase chain reaction and sequencing. RESULTS Nineteen strains were isolated from 32 throat swabs successfully.Fifteen strains were resistant to macrolide antibiotics according to the results of antibiotic susceptibility test. Once the strain was resistant to one of macrolide antibiotics,it would be resistant to the others. Sequencing results of the sensitive strains and the standard strain FH were completely same. Fifteen resistant strains presented A2063G point mutation in 23 SrRNA region Ⅴ, in which 2 examples showed the coexistence of the sensitive strain and the resistant strain. CONCLUSIONS Macrolide-resistant M. pneumoniae is common and serious at present. The antibiotic resistant isolate carries point mutations of the 23S rRNA region Ⅴ.
RESUMEN
Water-soluble carboxymethyl chitosan was prepared from dried shrimp shells. The intrinsic viscosities of its samples were measured to evaluate the stability of carboxymethyl chitosan. The influential factors of stability, such as heat, pH, ionic strength, ultraviolet radiation, and sterilization were studied. The results demonstrate that the intrinsic viscosities of water-soluble chitosan will be influenced, to a certain extent, by the change of pH and ionic strength. Ultraviolet radiation and sterilized processes not only exept influence on the degradation of chitosan, but also have prominent effects on the molecular structure of it. Besides, temperature will also affect the speed of degradation, and chitosan can be stored at a temperature as low as 2 degrees C-8 degrees C.
