AIM: To analyse the variety of the alkaloid and volatile oil from Herba Ephedrae after mix-fring with honey. METHODS: The volatile oil was analysed by GC-MS and the total alkaloids were determined by method of Chp. RESULTS: The volatile oil changed distinctly. The contents of Isolineole、p-Cymene、D-limonene、Evcalyptol、?-Terpinen increased evidently, but the contents of Benzaldehyde、Tetramethylpyrazine、p-Vinylanisole、?-Terpineol、?-Terpineol decreased and the contents of the total alkaloids decrease as well. CONCLUSION: The study provides a new experimental basis for the process theory of Herba Ephedrae.

In April 2016,the American Geriatrics Society(AGS)entered into a cooperative agreement with U.S.Department of Transportation.National Highway Traffic Safety Administration (NHTSA) updates and expands the Clinician's Guide to Assessing and Counseling Older Drivers to the 3rd Edition.The main goal of the Guide is to reduce traffic accidents and injuries to older drivers.According to the workflow of evaluation and management provided by Plan for Older Driver Safety(PODS),clinicians can conduct driving strategies after screening,evaluation and result analysis.The evaluation is done based on the Clinical Assessment of Driving Related Skills(CADReS) by a team including physicians,nurse practitioners,physician assistants,pharmacists,occupational therapists,driving rehabilitation specialists,and social workers.The CADReS including a series of assessment tools are used to evaluate in the key areas,such as vision,cognition,and motor/sensory function related to driving.Some measures will be taken based on the evaluation conclusions to help to explore the potential of driving safely for old adults.

Objective To observe the expression of matrix metalloproteinase(MMP-2, MMP-9 and vascular endothelial growth factor (VEGF) in retinoblastoma (RB) and its relationship with the differentiation and optic nerve infiltration of RB. Methods Forty paraffin specimens of pathological confirmed RB were studied. They were divided into differentiated group (15 cases) and undifferentiated group (25 cases) , optic nerve infiltration group( 13 cases) and without optic nerve infiltration group(27cases). The expression of MMP-2, MMP-9 and VEGF were detected by immunohistochemistry, their relationships with the differentiation and optic nerve infiltration were also analyzed. Results The positive rate of MMP-2, MMP-9 and VEGF expression in 40 RB cases were 52.5%, 57.5% and 72.5%respectively. The expression of MMP-2, MMP-9 and VEGF in the undifferentiated group were significantly higher than those in the differentiated group (χ2= 9. 037, 9. 253, 8. 095;P<0. 05). The expression ofMMP-2, MMP-9 and VEGF in RB with optic nerve infiltration group were significantly higher than those in RB without optic nerve infiltration group (χ2=11.045,10. 243, 8. 956;P<0. 05). The expression of MMP-2,MMP-9 had a positive correlation with the expression of VEGF in RB (r= 0. 126, 0. 314;P < 0. 05).Conclusions MMP-2, MMP-9 and VEGF expressed in RB tumor tissues. The expression of MMP-2,MMP-9 has a positive correlation with the expression of VEGF. The levels of MMP-2, MMP-9 and VEGF expression are related to optic nerve infiltration of RB cells.

Objective To evaluate the impact of the off -pump coronary artery bypass (OPCAB) on left ventricular(LV) function with transesophageal echocardiography(TEE). Methods Blood flow velocities of pulmonary vein (PV) and mitral valve (MV) were performed in 21 patients with coronary heart disease and myocardial infarction two weeks pre-OPCAB, and the left ventricular SV, CO and LVEF were measured by biplane Simpson′s method, the data were compared with the results observed one month post-OPCAB. Results The peak flow velocities of PV had significant difference between pre- and post-OPCAB(P

Objective To assess the changes of left ventricular function after off-pump coronary artery bypass (OPCAB) using Tei index. Methods Fourty-six patients of coronary artery disease, who had accepted OPCAB, were enrolled. Left ventricular ejection fraction(LVEF), E/A ratio at mitrial orifice(E/A), E deceleration time(EDT), isovolumic relaxation time(IVRT), ratio of systolic wave to diastolic wave of pulmonary vein flow(S/D) and Tei index were measured by transthoracic echocardiography before, immediate, 1 week, 1 month, 3 months and 6 months after OPCAB. Results Tei index decreased gradually as time went on after OPCAB and the differences were significant between different times(P

Objective To evaluate the clinical value of CT three-dimensional(3-D) imaging on diagnosing of bone and joint diseases.Methods The imaging findings of 357 cases proved by operation or clinic were analyzed retrospectively by the 3-D imaging.The diagnosis accuracy of 3-D imaging was compared with that of routine CT.3-D images were obtained by surface shade display(SSD),multi-planar reconstruction(MPR),maximum intensity project(MIP) and volume rendering(VR).Results In 357 patients,257 cases were traumatic disease,100 cases were non-traumatic disease.The diagnosis accuracy of 3-D imaging was 98.3%,which was higher than that of routine CT(P

Objective To analyse the imaging characteristics of solitary pulmonary nodules(SPNs) with the spiral CT, and detection clinical values of the definitive diagnosis to SPNs. Methods 32 cases of SPNs were identified by spiral CT, 9 cases of them were examinated by enhancement scanning. The diffrentical imaging features were analyzed. Results 24 cases were malignant in imaging(18 cases were identified), 8 cases were benign in imaging(6 cases were identified). 15 cases of malignant SPNs by clinical identified were smooth at edge; 6 cases of benign SPNs by clinical identified. 5 cases of them were anomaly;4 cases of them were burr;2 cases of them were bronchial sign and vesiclat sign.6 cases of the SPNs were calcified. 6 cases of SPNs(9 cases with contrasting) were benign in imaging, 3 cases of them were malignant in imaging. Conclusion The differential diagnostic of SPNs is difficult by spiral CT, but enhancement scanning and epidemiology combined with spiral CT is very valuable for definitive diagnosis.
