4.MicroRNAs and breast cancer
Chinese Journal of Clinical Oncology 2014;(2):87-93
MicroRNAs (miRNAs) are small non-coding RNA molecules with 21 to 24 nucleotides in length, which can regulate post-transcriptional gene expression by interacting with the 3' untranslated regions of the target mRNAs. MiRNAs are widely expressed in eukaryotic cells and involved in a variety of biological processes, such as in the development, differentiation, proliferation, and apop-tosis of cells. They also play essential roles in cell cycle regulation, migration, and tumor development. MicroRNA expression varies in different human tumors and is considered a powerful potential biological indicator in the development, diagnosis, treatment, and progno-sis of cancers. Breast cancer is one of the most common malignancies, and miRNA expression has been found to be differentially ex-pressed in various types of breast cancer. The expression and function of some miRNAs involved in breast cancer development, metasta-sis, and treatments are briefly summarized in this review.

AIM:To investigate the role of imperatorin in reversing the resistance of the PC 9 CD133+cell sub-sets to gefitinib.METHODS:MTT assay was performed to evaluate the viability of PC 9 cells treated with imperatorin and gefitinib.The expression of c-met, activation of caspases and phosphorylation of epidermal growth factor receptor (EGFR), PI3K and AKT in the PC9 cells treated with imperatorin and gefitinib were determined by Western blot .The percentage of CD133 +cell subsets population and the apoptotic rate of the PC 9 cells treated with imperatorin and gefitinib were analyzed by flow cytometry .RESULTS:The sensitivity of the PC 9 CD133 +cell subsets to gefitinib was significantly lower than that of the PC9 CD133 -cell subsets.Treatment with gefitinib alone significantly inhibited the protein levels of EGFR /PI3K/AKT in the PC9 CD133 -cell subsets but not the PC 9 CD133 +cell subsets .Treatment with gefitinib alone increased the percentage of CD133 +cell subsets population in the PC9 cells.However, combination of gefitinib with imperatorin signifi-cantly inhibited the enrichment of CD 133 +cell subsets population .Imperatorin down-regulated c-met expression , sugges-ting the c-met was the target of imperatorin in the PC9 CD133 +cell subsets.The results of MTT assay, Western blot analy-sis and flow cytometry indicated that imperatorin increased the gefitinib induced inhibition of PI 3K/AKT protein levels by down-regulating the expression of c-met, which subsequently induced the cleavage of caspases and apoptosis in the PC 9 CD133 +cell subsets.CONCLUSION:Imperatorin increases the sensitivity of lung cancer CD 133 +cell subsets to gefitinib by down-regulating the expression of c-met, and the synergistic anti-tumor effect exists between imperatorin and gefitinib .

Objective:To investigate the immume mechanism and protective effect of DNA vaccine pcD flaB against pathogenic leptospira infection. Methods: DNA vaccine pcD flaB was constructed by inserting flaB into the eucaryotic expressing plasmid pcDNA3. After guinea pigs were infected with leptospira, the protective rate was observed and specific anti leptospira antibody IgG were tested by ELISA. TNF activity was tested by cell proliferation. Results:The protective rate against leptospira infection was 100%. The specific antibody IgG generated peaked at the 6th week. Activity of TNF released by macrophage of guinea pigs given DNA vaccine was higher than that not given vaccine. Conclusion:DNA vaccine pcD flaB can protect guinea pigs from leptospira challenge infection by inducing humoral immune response and increasing TNF activity.

This paper described the practice of real-time booking registration, in which the patients may freely choose their visit time points, by such means as the outpatient clinic, website, telephone or short messaging. Such booking registration is an important measure to improve service quality at outpatient clinics; information technology is a prerequisite for real-time booking registration; pooling of outpatient ID number resources is key to setting up the booking registration; the prepaid card deposit practice makes booking registration more efficient; enhanced management for supporting services safeguards booking registration; cooperation with qualified third parties is an effective way to accomplish booking registration in a convenient manner. This paper also probed into other issues in relation to real-time booking registration.

Objective To investigate the effects of unilateral and bilateral electrical stimulation of the upper and lower limbs on motor function following cerebral infarction and the expressions of microtubule-associated protein-2 (MAP-2) and survivin in the infarction border zone of rats. Methods Adult male Sprague-Dawley (SD) rats were randomly divided into sham operation, control, impaired limb and bilateral limbs electrical stimulation groups (each group included 32 rats). Acute cerebral infarction was mimicked using a middle cerebral artery occlusion tech-nique. After cerebral infarction for 24 h, the rats were treated daily with or without electrical stimulation. A beam walking test (BWT) was used to measure limbs motor function and immunohistochemistry and HE staining were used to detect the expressions of MAP-2 and survivin in the border zone of infarcted area after electrical stimulation treat-ment for 3, 7, 14 and 21 d. Results Comparet with the control group treatment with electric stimulation led to BWT scores increasing significantly, and bilateral stimulation was more potent in ameliorating motor function thanstimulating the impaired limb only. The expression of MAP-2 was significantly higher in eleetrieal stimulation groups than in control group from the 7th of treatment, and it was higher in bilateral stimulation group than that in unilateral stimulation group from tbe 14th day of treatment. There was no significant difference in MAP-2 expression between bi-lateral stimulation group and sham operation group at the 21st day of treatment. In electrical stimulation groups, at every time point the expressions of survivin were obviously higher than that in sham operation group, and it was higher than that in control group and peaked at the 7tb and 14th day of treatment and in bilateral stimulation group it was no-tably higher than that in unilateral stimulation group. At the 21st d of treatment the level of survivin expression drop-per; however, there was no significant difference between unilateral and bilateral electrical stimulation groups. Con-clusions Treatment with electrical stimulation, particularly in bilateral limbs stimulation, could induce MAP-2 and survivin expressions in the infarction border zone of rats. It also could promote the recovery of motor function in para-lyzed limbs after cerebral infarction of rats. The improvement might involve the up-regulation of MAP-2 and survivin expressions.

Obesity is a rapidly growing international health problem. The association of fat mass and obesity associated(FTO) gene and obesity is becoming the hot topic in the gene research. FTO is a member of the nonheme dioxygenase [Fe(Ⅱ) and 2-oxoglutarate-dependent dioxygenases]superfamily. FTO levels in the brain,especially in the hypothalamus,participate in the central control of food intake. The mutation of FTO gene accentuates body mass index,hip circumference and total weight,leading to obesity.
