Objective To probe the effects of Danlongxingnaopian on hemorrheology and bulbar conjunctiva microcirculation(BCM)in dog and to explore its effects of activating the blood and eliminating the stagnant.Methods The blood stagnant syndrome model was reproduced by injecting dextran 500 into the vein.The BCM and the hemorrheology properties were detected and compared.Results Compared with the normal group,indexes of the model group such as whole blood relative viscosity,whole blood reducing viscosity and plasm viscosity improved,erythrocyte sedimentation rate and erythrocyte sedimentation rate K increased,erythrocyte aggregation index and erythrocyte transmutation index increased,BCM's morphological mark and flow habitus mark increased(P

Objective:To investigate the status of rumination in patients with primary glaucomatous visual field defect and explore the influencing factors.Methods:Totally 267 patients with primary glaucomatous visual field defect were selected via convenience sampling method. Invasive rumination, purpose rumination, and self-management behaviors among different visual field were compared. The main influencing factors of invasive rumination and purpose rumination were analyzed.Results:Total score of rumination in patients with primary glaucomatous visual field defect was (29.90±5.58) points, average item score of self-management behaviors was (2.81±0.31) points. There were no significant difference in invasive rumination, purpose rumination, self-management behaviors among different visual field ( P>0.05). Accidental injury, life adjustment, income of family per mouth and degree of education could explain 30.7% of the total invasive rumination variation; disease management, body function promotion and accidental injury could explain 11.1% of the total purpose rumination variation. Conclusions:Rumination and self-management behaviors in patients with primary glaucomatous visual field were at a lower middle level and middle level respectively. Medical staff should attach importance to assess the invasive rumination among these patients with accidental injury, poor ability of life adjustment, low income of family per mouth and low degree of education. Through lowering the negative experience, changing the cognitive and taking correct self-management behaviors, then prognosis of disease would be improved.

Objective To assess the feasibility of a novel 99Tcm labelled polypeptide analogue for interleukin-11 receptor ( IL11R) imaging in a bone metastases model for prostate cancer. Methods A novel circular polypeptide analogue of IL11 ( c( CGRRAGGSC ) ) was indirectly labeled with 99Tcm and the product was named as 99Tcm-DTPA-IL11 RR. The labeling efficiency, radiochemical purity and stability of the product were measured with paper chromatography and high performance liquid chromatography (HPLC). The biodistribution of 99Tcm-DTPA-IL11RR was investigated in 28 ICR normal mice. The organ radioactivity was measured as percentage activity of injection dose per gram of tissue ( %ID/g). The models of bone metastases from prostate cancer were established at the tibias of BALB/c nude mice bearing human prostate cancer PC-3 cells. The tumor bearing ( n= 5 ) and standard closed fracture nude mice models underwent both 99Tcm-DTPA-IL11RR and 99Tcm-methylene diphosphonate (MDP) scintigraphy study. The images were acquired at 0.5, 1,2, 4, 6, 8, 24 h after intravenous injection of the tracers. The competitive inhibition imaging was perfomed in three tumor bearing mice. One-way variance analysis was used. Results The labeling efficiency was 90.7%. The radiochemical purity of 99Tcm-DTPA-IL11RR in normal saline solution was (99.57 ±0.09)%, (99.29 ±0.18)%, (98.95 ±0.78)%, (98.67 ±0.11)%, (96.53 ±0.91)%, (95.20±0.70)%, (88.38 ±0.22)% and (36.17±1.29)% at room temperature after0, 1,2, 3, 4, 6, 8 and 24 h, respectively. The tracer radiochemical purity in the blood of ICR mice remained over 90% at 37 C for 6 h. The labeling compounds were excreted mainly through kidney. The peak uptake of bone ( ( 1.910 ±0.109) %ID/g) and liver ( (0.366 ±0.030) %ID/g) was at 4 h after injection. In the tumor bearing mice, the uptake of spine marrow and large joints of extremities was mild. The highest uptake at tumor region was at 4 h and persistent at 6-8 h after injection. The tumor to non-tumor ratios (T/NT) were 1.17 ±0.17, 2.20 ±0.29, 3.20 ±0.15, 3.67 ±0.23, 13.61±0.85, 9.45 ±0.37 and 3.33 ±0.30 at 0.5,1, 2, 4, 6, 8 and 24 h, respectively (F=621.54, P＜0.05). In the standard closed fracture models,high uptake of 99Tcm-MDP was shown at the fracture site, with no increased 99Tcm-DTPA-IL11RR uptake noted. The tumor uptake was significantly depressed after a pre-injection of the unlabeled polypeptide analogue. Conclusions The synthesis of 99Tcm-DTPA-IL11RR is stable and the labeling efficiency is high. It may be a potential molecular probe in metastatic bone imaging for prostate cancer.

Objective To analyze the CT and MRI features of primary central nervous system lymphoma ( PCNSL) and improve the accuracy of MRI diagnosis.Methods MRI features of 13 cases with PCNSL confirmed by pathology were retrospectively analyzed.All the cases were accepted MRI plain scanning and enhanced scanning. Tumor location, tumor size, signal intensity, enhancement characteristics, age distribution, cystic changes and the presence of calcification and intratumoral hemorrhage were assessed.Results Single lesion was found in 5 cases,and multiple lesions were found in 8 cases.Supra-tentorial lesions were found in 11 cases,the lesions involved both supra and infra tentorial were found in two cases.18 lesions located in deep-brain tissues,such as the thalamus,basal gan-glia,corpus callosum,midbrain and pons.7 lesions located at the surface of the brain,such as the temporal lobe,fron-tal lobe,occipital lobe and parietal lobe.The PCNSLs were found varied shapes in MRI,17 PCNSLs manifested irregu-lar shape,5 PCNSLs manifested round or ovoid shape,3 manifested butterfly shape.The average size of these lesions was 4.8cm.The PCNSLs manifested uniform or low T1 WI signal,uniform or slight high T2 WI signal,slight high or high signal on FLAIR,and slight high signal on DWI.11 cases manifested uniform signal and 2 cases manifested non-uniform signal.Different degrees of edema and mass effect were found combined with the lesions.The CT scan showed 6 cases were slighted high density,4 cases were equal density,3 cases were showed low density.Cystic chan-ges and calcifications were not found.In all cases,significant homogeneous enhancement was shown in 3 cases,moder-ate heterogeneous enhancement was shown in 1 case and mild enhancement was shown in 1 case.In multifocal dis-ease,significant homogeneous enhancement was shown in 14 cases,moderate heterogeneous enhancement was shown in 6 cases and mild enhancement was not shown.Conclusion The CT and MRI features of PCNSL of immunocompe-tent patients are always uniformity, whether T1 WIor T2 WI, while of immunodeficiency patients are complicated, all these features are helpful to make correct diagnosis.

24 hours) and versus control group(

0.05). Conclusion Enough high-purified LECs can be isolated by collagenase digestion procedure followed by immunomagnetic beads sorting. Post-thawed endothelial cells are proved to have high vitality and growth potential in vitro without significant morphological changes. Cryopreserved LECs may serve as a cell choice for research of lymphangiogenesis and lymphatic patterning.

The most common forms of treatment for amblyopia are occlusion therapy and pharmacologic penalization. But these methods can not recover all the visual deficits of amblyopes and there are some disadvantages of the treatment which need to be considered, including adverse effects, compliance and social stigma. Recently, some novel approaches are investigated for improving the effectiveness and compliance of treatment for amblyopia.

ObjectiveTo investigate the effect of clinical pathway teaching methord in nursing practice teaching. Methods80 junior college nursing students were randomly divided into control and experimental groups. Traditional clinical teaching method was given to control group, while the clinical pathway teaching method was given to observation group. Scores of comprehensive quality after departmental rotation and satisfaction rates of nursing students to teaching method in these two groups were evaluated. ResultsThe experimental group was significantly better than the control group ( P＜0.05 ), and the difference was statistically significant. ConclusionThe clinical pathway can significantly improve the quality of nursing practice teaching.
