Objective To discuss the application effect of fansclub informatization on the self-management of breast cancer patients. Methods A total of 240 breast cancer patients were equally divided into the experimental group and the control group by the random number table with 120 patients in each group. The control group was provided with routine health education, based on this, patients of the experimental group participated in the fans club. The compliance, tempering effect, readmission rate and the satisfaction degree were evaluated between the two groups one year later. Results A significant difference was observed between the two groups′ compliance (t=11.08, P<0.01), with the experimental group graded 69.27 ± 8.02 and the control group graded 48.76 ± 7.51. Moreover, in the experimental group, the angel of abduction, anteflexion, rear protraction, medial rotation, lateral rotation were respectively (170.13 ± 3.16)° , (172.45 ± 1.94)° , (46.71 ± 1.86)° , (81.30 ± 2.47)° and (85.18 ± 1.55)° ,which were significantly higher than the control group (125.16±1.93)°, (136.28±4.67)°, (34.63±2.68)°,(61.59±1.71)° and(85.18 ± 1.55)° (t=22.74-73.76,P<0.01). Further more, there were also remarkable differences (χ2=32.97, 54.21, 15.34, P<0.05) between the two groups on the consultative, readmission and the satisfaction degree, which in the experimental group were 91.67% (110/120), 81.67% (98/120), 96.67%(116/120), and in the control group were 55.83% (67/120), 47.50% (57/120), 84.17% (101/120). Conclusions The establishment of the fans club informatization remarkably improves the self-management of the breast cancer patients, which are worth popularizing.

Objective To explore the changes of different echocardiographic indices in patients receiving catheter ablation for atrial fibrillation with different outcomes. Methods 75 patients received catheter ablation for atrial fibrillation during the period of January 2012 to February 2014. Before and 6 monthes after ablation , all the patients were examined left atrial volume index (LAVi), left atrium pressure (LAP), and left atrial ejection force (LAF) with echocardiography. Then after 6 months, according to the outcomes of the procedure, we divided the patients into two groups and compared the changes of these three parameters. Results In sinus group, LAVi decreased while LAF increased after treatment [LAVi: (29.3 ± 1.9) vs. (41.2 ± 9.3), LAF:(1.31 ± 0.61) (kg·cm)/s2 vs. (0.83 ± 0.22) (kg·cm)/s2, P < 0.05]; But LAP did not change [(55.7 ± 23.3)mmHg vs. (58.9 ± 18.6)mmHg, P > 0.05]; while in recurrent group, there were no changes in LAVi, LAP, and LAF after treatment (P > 0.05). Conclusions Radiofrequency catheter ablation is safe and effective in treatment of atrial fibrillation, resulting in significant improvements in left atrial volume and cardiac function.

Objective To evaluate protective ventilation(PV) versus conventional ventilation(CV) for surgery in the prone position.Methods We searched PubMed, Embase, the Cochrane Library, WanFang Data and other Chinese databases to collect the randomized controlled trails (RCTs) on intraoperative PV in comparison with CV for surgery in the prone position.Two authors independently identified the studies, performed data extraction and assessed the risks of bias in the included studies according to the Cochrane Handbook for Systematic Reviews of Interventions.The reviewers conducted data analyses with RevMan software.Results A total of 9 RCTs involving 449 participants were included.The results showed that the incidence of postoperative pulmonary complications (RR 0.30, 95% CI 0.12~0.73, P<0.01) and peak pressure (MD-3.52, 95% CI-6.93~-0.11, P<0.05) were lower in the PV group.Intraoperative PaO2/FiO2 was higher (MD 37.28, 95% CI 22.67~51.89, P<0.001) and alveolar-arterial oxygen difference was lower (MD-45.50, 95% CI-61.35~-29.65, P<0.001) in the PV group.Conclusions Low tidal volume ventilation in combination with positive end-expiratory pressure (with or without recruitment maneuver) decreases postoperative pulmonary complications,reduces peak pressure and improves oxygenation for surgery in the prone position.

Objective To screen melanocortin 4 receptor (Mc4R) gene mutation by direct DNA sequencing in order to explore the mutation situation of Mc4R gene in simple obese children in Nanjing.Methods One hundred and five simple obese children(obesity group) and 127 healthy children(healthy control group) were examined for mutations of Mc4R gene.Body mass index(BMI)cutoff points for overweight and obesity adopted Chinese children and adolescents,recommended by China Working Group of Obesity,and all children had no other hereditary and metabolic abnormality.Touch-down PCR was performed to amplify the full length Mc4R gene,then direct DNA sequencing was used to analyze the Mc4R gene.The differences of biochemical index levels between obesity group and healthy control group were analyzed ,including alanine transaminase,aspartate transaminas,total protein,albumin,globulin,albumin/globulin,triglyceride,cholesterol,high density lipoprotein,cortisol,insulin and C peptide.Results There were significant differences of biochemical index levels between obesity group and healthy control group,including triglyceride,insulin level after dining 2 h,C peptide and BMI(Pa

Objective To obtain abundant human betacellulin(BTC) with biological activity. Methods The whole mature protein coding sequence of BTC gene was amplified by polymerase chain reaction(PCR) method applied to human pancreatic ?-cell tumors cDNA.The fragment was cloned into prokaryotic expression vector pET32a(+) plasmid.The recombinant plasmid was transformed into E.coli BL21 and the fusion protein was expressed under isopropyl-beta-D-thiogalactopyranoside(IPTG).The fusion protein was purified by Ni2+ affinity chromatography.SDS-PAGE and Western blot were employed to determine the expression and purification of the expected protein.BTC was added to culture NIH3T3 cells for 5 days,and cell proliferation was detected by MTT. Results Lots of fusion protein were produced,and the purified protein can stimulate the proliferation of NIH3T3 cells. Conclusion The human BTC can be successfully obtained from the pET32a(+) system with the biological activity of stimulating the proliferation of NIH3T3 cells.
