The successful separation of breast cancer stem cells (BCSCs) is the foundation of BCSC research.At present,people could gather BCSCs to some extent in a number of ways.However,as more and more biomarkers are found in BCSCs separation,the heterogeneity becomes a hot spot.How to gather BCSCs as much as possible and how to explain the heterogeneity could provide new insights in the treatment of breast cancer.

Objective To explore the effect of speech therapy on articulation disorder of indifferent kinds of children with cerebral palsy(CP).Methods 49 CP children with articulation disorder were divided into the common group(n=21)and family rehabilitation group(n=28).All children in the two groups were treated with systemic speech therapy,but those in the family rehabilitation group were added with family rehabilitation.The changes of articulation disorder of children in two groups before and after treatment were observed.Results After treatment,all children got improvement,but the effect of children with spastic type was superior to those with other CP types.The efficiency rate of the family rehabilitation group was 39.3%,that of the common group was 14.3%,there was a significant difference between two groups(P<0.05).Conclusion The children with different CP type have different therapeutic effects for articulation disorder,the family rehabilitation can improve the therapeutic effect.

A new species of genus shewarella Shewanellade decolorations S12, was isolated from activated sludge of a textile-printing waste-water treatment plant. In the anaerobic condition, S12 could conserve energy for growth by using Fe3 + as the terminal electron acceptor. At the optimal condition of pH8, temperature 30℃, ferric citrate 800mg/L, sodium lactate 2g/ L, yeast extract 0. 5g/ L , the cell growth increased with the raise of the amount of the Fe3+ reduction in 8k The effect of different carbon soucres, nitrogen sources, pH values and growth temperatures on the anaerobic Fe3 + reduction of Shewanella decolorations S12 was investigated. LB was favorable for Fe3 + reduction. Glucose and sodium lactate also were favorable for Fe3+ reduction. The cell growth and Fe3 + reduction increased with the raise of the amount of the yeast extract from 0 to 4g/L The amounts of the sodium lactate of 6g/ L and ferric citrate of 800mg/L were suitable for strain S12 growth and Fe3+ reduction. In the optimum initial pH value range of 6 -8 for Fe3+ reduction, strain S12 growth increased with the raise of the pH val- ue. Strain S12 could growth and reduce Fe3+ at the temperature range of 20 -40℃. The best temperature for strain S12 growth and Fe3 + reduction was 301.

OBJECTIVETo investigate the role of autophagy inhibitor chloroquine (CQ) in the proliferation of pulmonary arterial smooth muscle cells (PASMCs) in hypoxia conditions.

METHODSThe following groups in this study were set up: control group, hypoxia group, 50 micromol/L CQ + hypoxia group, 50 micromol/L CQ group. The viability of PASMCs in every group was detected by MTT assay. Autophagic vacuoles in the cells were observed by MDC staining. Protein expression of microtubule associated protein light chain 3 (LC3) was measured by Western blot. Migration of PASMCs was detected by wound healing assay.

RESULTSCompared with control group, no effect on the viability of PASMCs was observed treated by CQ alone. In 1% hypoxia group, cell viability increased significantly compared with that in control group. The number of autophagic vacuoles and the rate of cell migration and also protein expression of LC3-II were also markedly increased. Compared with hypoxia group, addition of CQ increased the number of autophagic vacuoles and the levels of LC3-II protein, but decreased the proliferation and migration of PASMCs.

CONCLUSIONHypoxia could activates autophagy and contributes to proliferation and migration of PASMCs, and autophagy inhibitor CQ could decrease the effect of hypoxia on PASMCs through inhibiting autophagy process.

OBJECTIVETo investigate the association of single nucleotide polymorphisms (SNPs) in the interleukin 17 (IL-17) gene and serum protein levels in patients with chronic hepatitis C virus (HCV) infection.

METHODSA total of 228 patients with chronic HCV infection and 81 healthy controls were enrolled in the study. The frequencies of IL-17 rs8193036 and rs2275913 polymorphisms were detected by the TaqMan SNP genotyping assay. Serum levels of IL-17 protein were detected by ELISA. Pairwise comparisons were made by the Chi-square test, and the significance of between-group differences was assessed by the Student's t-test with P less than 0.05.

RESULTSThe patients with chronic HCV infection and the healthy controls showed similar frequencies of the rs8193036 C/T allele (x2 = 1.428, P = 0.232) and the rs2275913 A/G allele (x2 = 0.106, P = 0.744). In addition, the two groups showed similar distribution of the rs8193036 CC (chronic HCV infection: 46.49% vs. healthy controls: 41.98%), CT (45.61% vs. 44.44%) and TT (7.89% vs. 13.58%) genotypes (x2 = 2.346, P = 0.309), and of the rs2275913 AA (16.23% vs. 13.58%), AG (48.25% vs. 50.62%) and GG (35.53% vs. 35.80%) genotypes (x2 = 0.340, P = 0.844). Subgroup analysis of chronic HCV infection patients stratified according to HCV genotypes 1 and 2 showed no differences in the distribution of rs8193036 and rs2275913 alleles (x2 = 1.127, P = 0.288; x2 = 1.088, P = 0.297) and genotypes (x2 = 2.825, P = 0.246; x2 = 0.970, P = 0.616). However, the chronic HCV infection group did show significantly higher levels of serum IL-17 than the controls (97.67+/-39.68 vs. 71.60+/-19.78 pg/ml, t = 2.414, P = 0.033).

CONCLUSIONChronic HCV infection is associated with increased serum IL-17; however, the IL-17 polymorphisms rs8193036 and rs2275913 were not associated with chronic HCV infection susceptibility in this study's Chinese cohort.

OBJECTIVETo investigate the outcomes of chronic hepatitis C (CHC) patients treated with antiviral regimens of interferon (IFN) plus ribavirin (RBV) using individualized doses and durations.

METHODSThis study was designed as an open-label, prospective clinical trial to analyze the virological responses of 169 CHC patients who received individualized dosages of IFNa-2b or pegylated (Peg)IFNa-2a combined with RBV based on their weight ( less than 60 kg or more than or equal to 60 kg), age (less than 65 years or 65-75 years), morbid state (liver cirrhosis or not), and complications (such as heart disease, diabetes, thyroid disorder). Treatment duration was calculated using the time required to induce HCV RNA negativity. The rates of virological response and adverse effects among the different groups were compared.

RESULTSThe IFNa-2b treatment was given to 116 patients, and PegIFNa-2a was given to 53 patients. Compared to the IFNa-2b group, the PegIFNa-2a group showed significantly higher rates of complete early virological response (cEVR; 76.7% vs. 92.5%, P less than 0.05) and sustained virological response (SVR; 53.6% vs. 92.3%, P less than 0.05) among the patients who had completed their course of treatment; the rapid virological response (RVR) rate was also higher for the PegIFNa-2a group but the difference did not reach statistical significance (48.7% vs. 60.4%, P more than 0.05). Seventy-eight patients received the routine dose, and 91 patients received the low dose; there were no significant differences between these two groups for RVR (53.8% vs. 58.9%, P more than 0.05), cEVR (78.0% vs. 80.8%, P more than 0.05), or SVR (65.5% vs. 58.3%, P more than 0.05).

CONCLUSIONUse of an individualized antiviral treatment strategy designed according to the patient's baseline condition, early viral kinetics, and tolerability to adverse reactions can achieve a high rate of SVR, as well as improve the safety, prognosis, and cost-effectiveness associated with treating CHC patients.

Whole body vibration training (WBVT) is a new kind of therapeutic exercise, which can improve musculoskeletal function and motor performance by transferring vibration stimulation to the body to affect neuromuscular activity. In this paper, the clinical efficacy, mechanism and parameter setting of WBVT in the treatment of chronic ankle instability were introduced through a systematic review of relevant literatures, so as to provide theoretical basis for the clinical application of this technique.
