Objective Observe the results and reality of the peripheral nerve stimulator in the obtu- rator nerve block in TURBt.Methods 18 cases received the peripheral nerve stimulator in obturator nerve block before TURBt.Results In 17cases obturator nerve reflection vanished;lcase had a little symptom of adductor spasm.Conclusion Obturator nerve block with the help of the nerve stimulator can increase the achievement and quality of obturator nerve block and avoid some complications caused by obturator nerve re- flection in TURBt,such as perforation of bladder and injury of nerve and vessel.

OBJECTIVETo detect the clinical value of the ECT bone scan in evaluating of the situation of infection control after hip knee arthroplasty.

METHODSThe clinical data were retrospectively analyzed in 62 patients, including 34 males and 28 females with an average age of 68.8 years old ranging from 65 to 74 years. The results of ECT bone scan, erythrocyte sedimentation rate, C-reactive protein were used to assess periprosthetic infection. The patients with positive ECT and ESR on CRP were considered to have periprosthetic infection; however, the patients with two or more negative, indexes were considered to have no infection.

RESULTSThe sensitivity, specificity, accurate rate of ECT were 75.0%, 88.9%, 87.1% respectively; ESR 50.0%, 72.2%, 69.4%; CRP 62.5%, 81.4%, 79.0%. The combination of the three methods were 87.5%, 96.3% and 95.2%,

CONCLUSIONCompared with ESR and CRP, ECT is a more effective way in the diagnosis of periprosthetic infection, which has great value and is worth popularizing.

Objective: The technological conditions for enzymatic extraction of calycosin glucoside and formononetin in Astragali Radix were optimized by using quadratic general rotary unitized design. Methods: On the base of single factors experiments, main factors that affecting the extraction efficiency, such as enzyme dosage, enzymatic hydrolysis time, adding water volume, and extraction time were selected. With the content of calycosin glucoside and formononetin as evaluation index, the process of enzymatic extraction of Astragali Radix was optimized by using quadratic general rotary unitized design. Results: The optimum enzymatic extraction process was as follows: enzyme dosage 340 mg, enzymatic hydrolysis time 110 min, adding water volume 19 times, and extraction time 150 min. Under these optimum conditions, the content of calycosin glucoside was 0.25 mg/g, and formononetin was 67.95 μg/g. Conclusion: The optimum enzymatic extraction process of Astragali Radix is stable and feasible.

Objective To compare the dissolution behavior between domestic trepibutone tablets and original reference product, and provide a basis for evaluating the quality consistency of generic drugs. Methods Four dissolution media recommended by Japanese Orange Book and a domestic standard dissolution media were selected to determined the dissolution profile,and f2 factor was calculated to investigate the consistency of stripping curves. Results In water,pH 4.0 and pH 1.2,the f2 of domestic formulation and reference formulation was under 50,and the dissolution profile was inconsistent.Dissolution behavior of domestic preparations of different manufacturers was dissimilar.In water,the f2 of domestic preparations of different batches of the same manufacturer was over 99.9,and the dissolution behavior was similar. Conclusion The dissolution method of existing domestic standard can not distinguish the dissolution behavior of different products,and it should be revised and completed.There is still great difference in quality between the domestic preparations and reference preparations.

Objective To evaluate the security and effect of combination of adjuvant hormonal thera- py and brachytherapy for localized prostate cancer.Methods 22 patients with T1-T2c prostate cancer were treated with transperineal ultrasound-guide 125I seeds prostate implantation and adjuvant hormonal therapy for 4～7 months.The hormonal therapy include 2-4 months before brachytherapy and 1～4 months after brachytherapy.Results The median operation time was ninety minutes,the median number of ~(125)I seeds used was 56.The follow up time was 12～48 months,the cases of PSA

Objective To observe the clinical effects after implantation of an aspherical intraocular lens Acrysof IQ.Design Prospective,randomized concurrent-controlled study.Participants 64 patients(64 eyes)with bilateral senile cataracts.Methods Pa- tients were operated with phacoemulsification and IOL implantation.They were divided randomly into 2 groups according to the table of random number:one group with Aerysof IQ(aspherical IOL)implantation and the other with Acrysof SN60AT(spherical IOL).Thor- ough ophthalmic examinations,including visual acuity,slit lamp examinations,fundoseopy,wavefront aberrometry,contrast sensitivity, were performed 1 week,1 month and 3 months after surgery.Main Outcome Measures Visual acuity,the best corrected visual acuity, spherical aberration(C 12),the root mean square of the total higher-order aberration(RMSh),and contrast sensitivity at 4 kinds of light backgrounds.Results At 1 postoperative month,RMSh(0.30?0.68?m)and C12(0.07,?0.04?m)in aspherical IOL group were signifi- cantly lower than those of the spherical IOL group(0.49?0.14?m,0.36?0.06?m)(P=0.00)with a 6.0 mm aperture.At 3 postoperative months the RMSh(0.30?0.07?m)and C12(0.06?0.06?m)in aspherical IOL group were significantly lower than those of the spherical IOL group(0.47?0.14?m,0.34?0.06?m)(P=0.00)with a 6.0 mm aperture.The asphefieal IOL(Acrysof IQ)provided statistically sig- nificant better contrast sensitivity at all spatial frequencies under mesopic conditions(3 cd/m~2)with and without glare(P

To establish the local quality standard for Dendrobii devoniani caulis from Longling, Yunnan, the pharmacognostic characteristics microscopic characteristics and TLC identification were developed. Sulfuric acid-phenol method was used to determine the content of polysaccharide. An HPLC method was adopted to determine the content of mannose, and extractives were determined according to the procedures recorded in the Appendix of Chinese Pharmacopoeia(2010). The results showed a strong characteristics microscopic of Dendrobii devoniani caulis, and its TLC identification had a good resolution with clear spots; the content of polysaccharide is 35.7% -52.1% (average 42.7%), mannose 27.8%-46.1% (average 35.8%), and extract 4.5%-10.6% (average 7.38%). The method is simple, accurate and reliable, with good reproducibility. The established standard is acceptable for quality evaluation of Dendrobii devoniani caulis from Longling, Yunnan.
