Objective To study the correlation between social support for nurses and patients'satisfaction degree with nursing work.Methods The social support for nurses was evaluated by Xiao Shui-yuan's Social Support Rate Scale(SSRS).The patients'satisfaction degree with nursing work was assessed by self-designed inventory.Results The three dimensions of social support and its total score were positively correlated with patients'satisfaction degree(r=0.21～0.32).Not only the subjective support and patients satisfaction degree with nurses's care but also the objective support and patients satisfaction degree with nurses's knowledge and technique was hishly correlated.The correlation also existed in nursess'utilization degree of social support and patients' satisfaction degree with nurses's knowledge and tech-nique.Conclusion The social support for nurses was correlatd with patients'satisfaction degree with nursing work.Dood social support may contribute to alleviated patients'satisfaction degree

Objective To investigate the value of application of multi-slice helical CT(MSCT) indiagnosis of basicranial fracture. Methods Sixty-two patients with basicranial fracture were scanned withthin-section scanning mode after conventional CT scanning The images were transferred to the work-station for reconstruction including multiplanar reconstruction (MPR), volume rendering (VR). Comparison between thin-section scanning images and conventional CT scanning images were performed. Results Compared with the conventional CT scanning (67.9% and 45.0% respectively),the rates of fracture displayed of images acquired from thin-section scanning in diagnosis of fractures of anterior and middle cranial fossa (100.0% and 95.0% respectively) ,P＜0.01. The two scanning mode in diagnosis of fractures of posterior cranial fossa( 88.9% and 100.0% respectively )differed from each other unstatistically(P＞0.05 ). ConclusionThe thin-section scanning of MSCT can improve the diagnostic correctness of basicranial fracture.

OBJECTIVETo investigate the mechanism underlying the inhibitory effect of STOML-2 overexpression on apoptosis of human cervical squamous carcinoma Siha cells.

METHODSSiha cells were transfected with an adenoviral vector carrying STOML-2, and 72 h later STOML-2 expression and the proliferation of the cells were detected by Western blotting and MTT assay. The transfected cells were treated with IC50 Cisplatin for 24 h, and the morphological changes of cells were observed using fluorescence, and the cell apoptosis was analyzed using flow cytomerty; the expression levels of proteins related with mitochondrial apoptosis pathway, including caspase-3, cleaved caspase-3, Bcl-2, Bax and cytochrome C (Cyt C), were detected by Western blotting.

RESULTSWestern blotting showed a significantly increased STOML-2 expression in the transfected cells. Overexpression of STOML-2 obviously promoted the proliferation of Siha cells. The STOML-2-overexpressing cells exhibited an obvious resistance to IC50 Cisplatin-induced apoptosis as shown by both fluorescence microscopy and flow cytometry and presented with decreased expressions of cleaved caspase-3, Bax, and cytosol Cyt C and increased expressions of caspase-3, Bcl-2, and mitochondrial Cyt C.

CONCLUSIONSOverexpression of STOML-2 can enhance the proliferation of Siha cells by inhibiting cell apoptosis possibly through the mitochondrial apoptosis pathway.

Objective To explore the limits of fluid-inversion prepared diffusion weighted imaging (FLIPD) in detection of acute cerebral ischemic lesions.Methods From January 2012 to March 2014,forty-nine patients (33 males,16 females,age (55.6± 12.3) years) clinically diagnosed as transient ischemic attack (TIA) were included.Patients underwent brain MRI (conventional diffusion weighted imaging (DWI) and FLIPD) within 3 d after the onset of TIA.The detection ability of MRI with the two sequences was compared,and the relative signal intensity (rSI) and apparent diffusion coefficient (ADC) of acute ischemic lesions based on two sequences were compared.Kappa test and two-sample t test were used to analyze the data.Results A total of 87 acute ischemic lesions were detected in 21 patients by conventional DWI,and 54 were detected in 19 patients by FLIPD (Kappa=0.916,P＜0.05).The rSI of ischemic lesions on FLIPD was significantly lower than that on conventional DWI (1.37±0.22 vs 1.57±0.26;t=6.647,P＜0.001).The ADC value of ischemic lesions on FLIPD was slightly lower than that on conventional DWI:(0.54 ±0.10) ×10-3 mm2/s vs (0.57±0.13)×10-3 mm2/s (t=2.120,P＜0.05).The missed lesions on FLIPD were located in the white matter (n =18),cerebellum and brainstem (n =8),and the cortex (n =7).Conclusions A slight diffuse abnormality may be missed on FLIPD,so this method is not suitable for the detection of acute ischemic lesions.FLIPD technology still needs improvement.
