OBJECTIVETo evaluate the early clinical and radiographic outcome of scaphoid non-unions treated with Acutrak headless compression screw.

METHODSFrom January 2008 to July 2011,21 patients with scaphoid non-union were treated in our department. There were 18 males and 3 females with a mean age of (23.6 +/- 4.6) years; 12 cases were on right hand and 9 were on left. According to Herbert-Fisher classification, there were 10 cases with type D1, 7 cases with type D2, 3 cases with type D3, and 1 case with type D4. The mean time from injury to operation was (12.4 +/- 2.7) months. All patients were treated with Acutrak headless compression screw fixation (6 cases received 2 screws fixation, 15 cases received 1 screw fixation, and Matti-Russe bone grafting was applied in 7 cases). The carpal height, the scaphoid index and changes of the scapholunate angle were assessed before and after the operation. Range of motion and grip strength were recorded and the wrist function was assessed according to the Patient-Rated Wrist Evaluation (PRWE).

RESULTSAverage duration of follow-up was (21.3 +/- 3.6) months. All the patients attained radiological union in a mean time of (13.3 +/- 2.4) weeks following the operation. No obvious complications were recorded. The surgical treatment allowed the preoperative mean scaphoid index of 0.61 +/- 0.13 and the preoperative mean scapholunate angle of (59.4 +/- 6.8) degree to be improved to 0.69 +/- 0.10 and (44.3 +/- 8.2)degree postoperatively, respectively. There was a substantial improvement in grip strength and pain amelioration after surgery. The preoperative mean PRWE score of 45.2 +/- 4.7 was improved to 76.1 +/- 5.2 postoperatively. All patients returned back to the original work,the average time from surgery to work was (6.0 +/- 1.1) months.

CONCLUSIONFor scaphoid non-unions, Acutrak headless compression screw fixation can provide anatomical reduction, provide satisfactory results with a high union rate, well return of function and minimal complications in the early stage.

HER2, a member of epidermal growth factor receptor family proteins, is overexpressed in about 30% of human breast cancer. Increased levels of HER2 are associated with poor patient prognosis and enhanced metastasis. RNA interference (RNAi) is developed recently as a new technique which can inhibit gene expression specifically in mammalian cells. On the basis of previous study,in which two target sequences with favorable RNAi effect on HER2 were identified, a series of dual promoter siRNA-expressing vectors containing two opposing U6 and H1 promoters were constructed. After transfection of HER2-overexpressing SKBR3 breast cancer cells with the siRNA-expressing vectors, downregulation of HER2 was identified quantitatively. Subsequently, the siRNA-expressing cassettes were subcloned into lentiviral vectors by LR recombination reaction and lentivirus was prepared successfully. The results from infection of SKBR3 cells with siRNA-expressing lentivirus demonstrated that lentiviral-mediated RNAi could downregulate HER2 expression efficiently through fluorescent quantitative PCR (FQ-PCR), western blot, and FACS analysis. Furthermore, cell growth was inhibited in cell proliferation assay after treatment with siRNA lentivirus.A new tool for clarifying the function of HER2 in cancer metastasis and developing the gene therapy drug was offered.

Objective To survey and analyze the situation of nurses about music therapy. Methods A questionnaire survey was used to investigate 250 nurses. Results In addition tO the cognition of the major role of music therapy(P>0.05),for nurses with the undergraduate and higher level qualifications, there were significant differences in its meaning, the main mechanism, the main style, the requirements of environment and perpetrators. The choice of music types, aesthetic fatigue from music, the patient's quality requirements, and other aspects of cognition compared to the nurses with a degree low than a bachelor degree(P<0.05).Main source of knowledge Was from the media channels.46.1 percent of the nurses didn't Use music therapy.31.4 percent of the nurses rarely used it. Conclusions Nurses with different qualifications have different awareness of music therapy. The professional music therapy of nurses should be raised. The source of music knowledge should be increased, at the sanle time music therapy should be intensified in the nursing work.

Background:Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare but potentially life?threatening congenital heart defect. A retrospective analysis was carried out to elucidate the surgical outcomes of ALCAPA in infants and children using follow?up echocardiography. Methods: From September 2008 to March 2017, 26 children diagnosed with ALCAPA underwent left coronary re?implantation. All surviving patients received echocardiography during follow?up. Results: The mortality rate after the operation was 11.5%. Before repair, twenty patients (76.9%) presented with left ventricular (LV) dysfunction. The mean Z?score of the preoperative LV end?diastolic diameter was 4.42 ± 2.09. Mitral regurgitation (MR) was present in all patients. Two patients (7.7%), both with mitral valve prolapse, underwent mitral valve repair at the time of ALCAPA repair. Two children required postoperative extracorporeal membrane oxygenation. LV function normalized at a median time of 5.3 months (range:0.5–36.0 months). The Z?score of the LV end?diastolic diameter decreased simultaneously. The degree of MR gradually decreased in all surviving patients.All patients had patency of the proximal left coronary artery confirmed by echocardiography at the most recent follow?up. Six patients (26.1%) showed supravalvar pulmonary stenosis and seven patients (30.4%) showed right pulmonary stenosis during follow?up. Conclusions: Coronary re?implantation was effective for rebuilding a dual coronary system in patients with ALCAPA and resulted in progressive improved LV function and reduced functional MR. Echocardiography was valuable for evaluating the outcomes. LV function, the degree of MR, and possible complications could be detected with follow?up echocardiography.

OBJECTIVETo investigate effects of total flavonoid fraction of Asttragalus complanatus on blood pressure in conscious spontaneously hypertensive rats(SHR) and hemodynamics in anesthetized SHR.

METHODBlood pressure was recorded with tail-culf method and hemodynamics was recorded with polygraph after administration of total flavonoid fraction of Asttragalus complanatus.

RESULTTotal flavonoid fraction of Asttragalus complanatus (100, 200 mg.kg-1) could decrease blood pressure of conscious SHR(decreasing 7.1%, P < 0.05 and 9.3%, P < 0.01 respectively). Meanwhile, there was no significant change in heart rate(HR). R Br (200 mg.kg-1) could decrease total peripheral resistance (TPR) (decreasing 20%, P < 0.05) but did not influence the cardiac output(CO) and heart rate in anesthetized SHR.

CONCLUSIONTotal flavonoid fraction of Asttragalus complanatus possesses obvious hypotensive effect, mainly by means of decreasing the TPR.

OBJECTIVETo investigate the effects of very low-density lipoprotein (VLDL) on cellular lipid accumulation and the expression of monocyte chemoattractant protein-1 (MCP-1) in human mesangial cells.

METHODSAn established stable human mesangial cell line (HMCL) was used in all experiments. VLDL-induced cellular lipid deposition was visualized by Oil Red O staining and analyzed quantitatively by standard enzymatic procedures. MCP-1 mRNA and protein expression levels in treated HMCLs were determined by real-time quantitative RT-PCR and enzyme-linked immunosorbent assay, respectively. For adhesion study, HMCLs were treated with VLDL for 12 hours, followed by a one-hour incubation with THP-1 cells.

RESULTSVLDL induced cellular lipid accumulation in HMCLs in a time- (0-24 h) and dose- (0-200 microg/ml) dependent manner, and the principal component of accumulated lipid is triglyceride. In HMCLs, MCP-1 mRNA expression was promoted by VLDL in a time- (0-6 h) and dose- (0-100 microg/ml) dependent manner, and VLDL also enhanced MCP-1 secretion in a dose-dependent manner. Such an effect was accompanied by increased adhesion of monocytes to HMCLs.

CONCLUSIONSVLDL can induce cellular triglyceride accumulation and upregulate the expression of MCP-1 in human mesangial cells. Hence, VLDL may be involved in the pathogenesis of lipid-mediated renal injury.
