Objective To establish the determination method of Astragaloside Ⅳ in Shenqi-wuweizi tablet. Methods A high performance liquid chromatography method with evaporate light scattering detection was adopted. The analytes were successfully separated with Agilent-C18 column using acetonitrile and water (30:70) as mobile phase at 1.0ml/min. The parameter of ELSD was set at a evaporation tube temperature of 90℃ and nebulization at 50℃. The column temperature was set at 35℃. Results The linear range of Astragaloside Ⅳ was 41.68~521μg/ml, and the calibration curve was lnA=1.5461lnC+5.9564 with a coefficient of 0.9995 (n=6). The average recovery rate was 100.42%, with a relative standard deviation of 1.74%. Conclusion The method was simple, rapid, sensitive and accurate. Besides, it showed good repeatability as well as specificity, suitable for the quality control of Shenqi-wuweizi tablet.

Objective:To compare the values of medical image technologies in evaluating the tansperineal laser ablation (TPLA) in canine prostate.Methods:TPLA (3 W/600 J and 3 W/1 200 J) were operated in the prostate of six adult male beagles guided by transrectal ultrasound (TRUS). TRUS, transrectal contrast-enhanced ultrasound (TR-CEUS) and multiparameter magnetic resonance imaging (mpMRI) were used to evaluate the ablation on the day of TPLA, one week and one month after TPLA. The animals were sacrificed for pathology to calculate the volume of the ablation. SPSS 22.0 software was used for statistical analysis.Results:TRUS could be used to guide and observe the puncture and ablation process during TPLA. TR-CEUS and contrast enhanced MRI showed good consistency in the volume of ablation ( P>0.05). One month after TPLA, the ablation volume were (1.69±0.51)ml vs (1.73±0.36)ml vs (1.52±0.41)ml (3 W/600 J) and (2.23±0.54)ml vs (2.34±0.29)ml vs (2.19±0.34)ml (3 W/1 200 J) measured by the two medical image technologies and pathology, with good consistency ( P>0.05). Conclusions:TRUS can be used to guide and observe the puncture and ablation process during TPLA. TR-CEUS and mpMRI can be used for postoperative evaluation and follow-up of TPLA. The former has advantages of real-time and low price, which can be promoted and applied in clinical practice.

It was to introduce professor 's experience in the treatment of oculomotor nerve palsy with acupuncture based on the interactions of twelve muscle regions and opposing needling theory. In the treatment, the TCM syndrome differentiation is taken as the general principle, the theory of the interactions of twelve muscle regions and opposing needling as the specific feature. The contrary needling is used at Hanyan (GB 4) and Juliao (ST 3) on the healthy side. The meridian-collateral and the exterior-interior differentiations are adopted to identify the syndromes. At the early stage of the disease, the treating principle focuses on expelling wind, eliminating cold and promoting the circulations of meridians and collaterals. The shallow needling, less acupoints and gentle stimulation are required. At the middle and late stage, the treating principle concentrates on strengthening the antipathogenic and harmonizing and blood. The deep needling, the multiple acupoints and the strong stimulation are applied. Additionally, the four-needling technique at Fengchi (GB 20), the multiple shallow needling at the eyelid margin, the opposing needling and the quantity of needling sensation are used in combination, which were developed by professor . With those comprehensivemethods, the symptoms of oculomotor nerve palsy are relieved and the significant clinical therapeutic effects achieved.
