Girdin protein is a kind of actin binding protein,which has the complex molecular structure and takes part in a variety of signaling pathways related with causing cancer.The biological characteristics of Gir-din protein have close association with the proliferation and invasion of malignant tumor.Recent studies have shown that Girdin protein is closely related with occurrence and progress of breast cancer.Girdin protein expres-sion in breast cancer cells can not only promote the progress of breast cancer,but also affect the lymph node me-tastasis and prognosis.Therefore Girdin protein is expected as an independent biomarker to provide a new direc-tion for breast cancer treatment.

Electric fields have special biological effects for its heating and non-heating effects. Heating effects are about the technology of radio frequency and microwave thermotherapy while non-heating effects are alternating electric field and pulsed electric field. These electric fields have significant effects for tumor treating.

Objective To explore the role of hemoglobin (Hb) level in mortality and morbidity of chronic kidney disease (CKD)patients,aiming to give some evidence for therapy of anemia.Methods Randomized,clinical trials (RCTs) were identified by searching Medline,Embase and the Cochrane library.All the analyses were performed using the Revman software available free from the Cochrane collaboration.Results Twenty-three trials involving 10 204 patients were identified.Overall,the high Hb target was associated with increased risk of all-cause mortality (RR=1.10,95％ CI 1.00 to 1.21),hypertension (RR=1.40,95％ CI 1.12 to 1.75),stroke and hospitalization (RR=1.07,95％ CI 1.00 to 1.14) compared with low Hb target (P＜0.05).No significant difference was found in the risks of non-fatal mycardial infarction (RR=1.13,95％ CI 0.79 to 1.62) and renal replacement therapy (RR =1.00,95％ CI 0.85 to 1.18).Conclusions Targeting low Hb target is beneficial to CKD patients based on reduced risk of hypertension,hospitalization,stroke and all-cause mortality.However,no significant difference is found in non-fatal mycardial infarction and renal replacement therapy.

Objective To evaluate the effect of comprehensive intervention measures on preventing and controlling surgical site infection (SSI)in patients undergoing total abdominal hysterectomy.Methods Patients undergoing total abdominal hysterectomy in a hospital between January 2011 and December 2014 were investigated retrospec-tively,patients in 2011 were as control group,from January 2012,a prospective monitoring on SSI was initiated, comprehensive intervention measures were taken,patients between January 2012 and December 2014 were as inter-vention group,SSI before and after the intervention was compared.Results A total of 1 052 patients undergoing to-tal abdominal hysterectomy were investigated,267 cases were monitored before intervention,25 patients (9.36%) developed healthcare-associated infection (HAI),12(4.49%)of whom were with SSI;785 cases were monitored af-ter intervention,13 (1 .66%)of whom were with SSI,incidence of SSI in 2012,2013,and 2014 were 2.31 %, 1 .89%,and 0.77% respectively,there was a decreasing tendency(χ2 =7.30,P <0.01 ).Conclusion Prospective monitoring on SSI and comprehensive intervention can reduce the incidence of SSI in patients undergoing total abdominal hysterectomy.

BACKGROUND:Because chondrocytes have no regeneration ability, to select suitable seed cels is the primary problem to repair cartilage defects.
OBJECTIVE:To investigate the effect of alogeneicversus heterologous bone marrow mesenchymal stem cels (BMSCs) in repairing laryngeal cartilage defects after chondrogenic induction.
METHODS:BMSCs from human and rabbits were isolated and cultured. Passage 3 cels were cultured in chondrogenic induction medium containing transforming transforming growth factor beta 1 and bone morphogenetic protein, and then were dropped onto a poly(lactic-co-glycolic acid) (PLGA) scaffold. Thirty New Zealand rabbits were randomly assigned into three groups: blank control group, human BMSCs group, rabbit BMSCs group. Animal models of laryngeal cartilage defects were made in the three groups. After modeling, saline-soaked PLGA scaffold, PLAG scaffold with human BMSCs or with rabbit BMSCs were implanted respectively into the rabbits in the normal blank, human BMSCs and rabbit BMSCs groups. The expression of type II colagen in the larynx and its surrounding tissues was detected by immunohistochemistry at 4 and 8 weeks postoperatively.
RESULTS AND CONCLUSION: The animals in each group breathed normaly with no presence of wheezing, and their eating and activity were good. Moreover, there was no purulency or infection in the three groups. At 4 and 8 weeks after operation, the positive rates of type II colagen in the two BMSCs groups were significantly higher than that in the blank control group (P < 0.05). There was no significant difference between two BMSCs groups (P > 0.05). These results show that both alogeneic and heterologous BMSCs have good therapeutic effects on the repair of laryngeal cartilage defects in rabbits.

Objective To investigate the safety and efficacy of a 3-pulmonary vein (PV) isolation approach in treating paroxysmal atrial fibrillation (AF). Methods Radiofrequency catheter ablation was used to eliminate PV potential in 11 patterns with frequent paroxysmal AF refractory to anti-arrhythmic agents. During sinus rhythm, PV potential was mapped in the left and right superior PVs and left inferior PV. The procedural success was defined as the elimination of PV potential in the 3 PVs. Restults PV potential was identified and abolished in a total of 24 PVs, mostly in the left and right superior PV. There was no pulmonary stenosis or other complications during or after the procedures. AF recurred in one patient after an average of 12 ± 3 month follow-up. Conclusions PV potemials were present mostly in the left or right superior PV. The 3-PVs isolation approach is safe and effective in preventing drug-resistant paroxysmal AF.

Objective:To explore the application value of continuous positive airway pressure ( CPAP) in the treatment of obstruc-tive sleep apnea hypopnea syndrome (OSAHS ) complicated with coronary heart disease (CHD).Methods:Totally 50 patients with OSAHS complicated with CHD from June 2012 to June 2014 in our hospital were randomly divided into the control group and CPAP group with 25 ones in each .The patients in the control group were treated with the conventional drug therapy for coronary heart disease , while those in CPAP group were treated with CPAP additionally .After 6-month treatment, PSG index, clinical symptoms, arrhythmia and ischemia electrocardiogram changes of the patients in the two groups were compared .Results:After the 6-month treatment , AHI and oxygen desaturation index in CPAP group were significantly decreased when compared with those before the treatment , and the min-imum value of SaO2 and the average value of SaO 2 were higher than those before the treatment (P<0.01), and the above indices were better than those in the control group (P<0.01).The incidence rate of chest pain and chest tightness , arrhythmia, times of myocardi-al ischemia in a day and time of myocardial ischemia in a day were decreased after the treatment (P<0.01), and the decrease in CPAP group was more notable than that in the control group (P<0.01).Conclusion: CPAP combined with the conventional drug therapy for coronary heart disease can improve the oxygen concentration and reduce the incidence of arrhythmia and myocardial ischemia in the patients with OSAHS with CHD , which can be widely used in clinics .

Aim To clarify the regulation role of ca-thepsin B ( Cat B ) in cell proliferation and apoptosis induced by SAHA in ER-positive breast cancer cell line MCF-7.Methods MTT was used to screen the optimal concentration and treatment time of SAHA . The expression levels of related proteins were deter-mined by ELISA , and the morphological changes were observed through time-lapse live cell imaging acquisi-tion.Cell viability and apoptosis assay in MCF-7 cells were assessed by Muse Cell Analyzer with SAHA and /or Cystatin C treatment .Results MTT assay showed that the anti-tumor efficacy of SAHA was significant . The optimal concentration and treatment time were 10μmol? L-1 and 24 h respectively . ELISA assay showed that SAHA could induce expression of Cat B in MCF-7 cells.Real-time live-cell imaging experiments demonstrated that the combination treatment of Cystatin C and SAHA significantly resumed the inhibitory effect caused by SAHA alone .Cytology test showed that SA-HA alone obviously depressed the cell viability and in-duced apoptosis . However , the effect was reversed with the combination of Cystatin C .Conclusion Cat B plays an important role in apoptosis induced by SAHA in ER +breast cancer cells MCF-7.
