ObjectiveTo confirm the effect of miR-93 inhibitor in glioma cell growth and invasion.MethodsMalignant glioma cells were transfected with miR-93 inhibitor by lipofectamin to downregulate their overexpression of miR-93.Real time-PCR was taken to measure miR-93 expression after transfection.The cell cycle kinetics and cell growth rate were detected by flowcytometry and MTT assay,the cell proliferative ability was evaluated by soft agar assay,and the invasive ability was detected by transwell assay.ResultsThe highlevel expression of miR-93 was downregulated effectively in glioma cells after transfecting the miR-93 inhibitor.Meanwhile,the cell cycle progress was delayed,S phase cells were reduced,the speed of growth was slowed,cloning formation ability was receded,the number of cells through the matrigel was reduced,and invasive ability was significantly repressed.ConclusionDownregulation of miR-93 expression could inhibit the proliferative ability and invasive ability of glioma cells.

Objective To evaluate the feasibility and therapeutic effect of kyphoplasty in treating severe osteoporotic vertebral compressive fractures. Methods Thirty-five patients (48 vertebral bodies) with severe osteoporotic compressive fractures were included. There were 33 females and 2 males with the mean age of 74.2 years. The average compressive rate of the affected vertebral bodies was 77.0%. The thoracolumbar vertebrae were treated with kyphoplasties. Percutaneous puncture direction was adjusted according to compressive rate and shape of the vertebral bodies. The inflatable bone tamp was inserted into the fractured vertebral body. The balloon was inflated with low pressure and dilate-relieve-dilate method was applied. The balloon was deflated and withdrawn, leaving a cavity within the vertebral body, which then fulfilled with visualized bone cement. Preoperative and postoperative symptom level, complications and radiographic findings were recorded. Results All 35 patients tolerated procedure well. The mean heights of the anterior, mid and posterior vertebral body had improved from (0.8±0.1) cm, (0.8±0.2) cm, (2.1 ±0.8) cm preoperatively to (1.2±0.3) cm, (1.3±0.2) cm, (2.3±1.0) cm respectively after operation (P ＜0.05). There was significance difference between preoperative and postoperative heights of the anterior and mid vertebral body. The mean kyphosis was improved from 28.2°±5.2° before operation to 19.1°±4.9° after operation. Conclusion Kyphoplasty is feasible and effective for severe osteoporotic vertebral compressive fractures.

ObjectiveTo study the effects of placental transfusion of umbilical cord milking on very low birth weight (VLBW) infants. Methods Fifty-seven VLBW infants born from September 2011 to May 2014 who had umbilical cord milking at birth were selected as experimental group. Sixty-one VLBW infants born from January 2008 to August 2011 who had normal cord clamping at birth were selected as control group. The complications of VLBW infants, blood transfusion, frequency of using pulmonary surfactant (PS), the duration of mechanical ventilation, the duration of oxygen and mortality were compared between two groups.Results The incidence of severe asphyxia, IVH and anemia was signiifcantly lower in experimental group than in control group (P< 0.05). The blood transfusion and transfusion volume, duration of mechanical ventilation, and duration of oxy-gen were signiifcantly lower in experimental group than in control group (P< 0.05).Conclusions Umbilical cord milking can reduce the incidence of severe asphyxia, IVH and anemia. It also can reduce the blood transfusion, the duration of mechanical ventilation, and the duration of oxygen in VLBW infants.

Objective:This study aimed to explore the effect of Yes-associated protein (YAP) on the growth of the human glioma cell line LN229. Methods:YAPsiRNA was transfected into LN229 cells to knock down the YAP expression. The downregulation of the YAP expression was identified through Western Blot analysis. Colorimetric assay using methyl-thiazolyl-tetrazolium was applied to evaluate cell proliferation ability. Cell invasive activity was examined using Transwell assay. Flow cytometry and AnnexinV were used to detect cell cycle and apoptosis, respectively. The relevant molecules regulating proliferation, invasion, cell cycle progression, and apoptosis were examined through Western Blot analysis. Results:The YAP expression was downregulated after YAPsiRNA was trans-fected into LN229 glioma cells. Reduced YAP expression could arrest the cell cycle at G0/G1 phase, inhibit cell proliferation and inva-sion, and promote apoptosis. The expression of the proliferating cell nuclear antigen (Ki-67), matrix metallopeptidase-9 (MMP-9), cy-clin D1, and Bcl-2 were downregulated. Conclusion:The downregulation of YAP in LN229 cells suppresses cell proliferation and inva-sion, as well as promotes cell apoptosis. This study provides a novel evidence for further study on Hippo-YAP signal pathway in molec-ular pathology of glioma.
