Objective To study the content of taxol in different parts of Taxus Yunnanensis and the effects of different growth time on taxol content. Method A HPLC method was developed for the detetmination of taxol content in bark, needle, twig, root from Taxus Yunnanensi, and the effects of different growth time. Results Taxol content in bark was the highest, that in root was the lowest and that in needle and twig were higher. Taxol content was higher with the growth time in needle and twig of Taxus Yunnanensi. Conclution It was significant to take taxol from needle and twig of Taxus Yunnanensis which is more than five years growth time.

Objective To control the quality of Herba Leonuri by studying the content of stachydrine hydrochloride in different parts of it. Method A HPLC method was developed for the content detetmination of stachydrine hydrochloride in flower, stem, leafage from Herba Leonuri. Spherisorb SCX colum was used with mobile phase of 20 mmol/L sodium dihydrogen phosphate (containing 0.04% triethylamine and 0.15% phosphoric acid). The colum temperature was 25 ℃, the detective wavelength was 192 nm. Results Stachydrine hydrochloride content was the highest in leafage and the lowest in stem. Conclusion To ensure the quality of Herba Leonuri, it is significant to choose medical material with more leafage.

Objective:To evaluate the efficacy and safety of talc poudrage pleurodesis via semi-rigid medical thoracoscopy in the treatment of malignant pleural effusions,as well as the factors that may influence the outcomes.Methods:A series of 27 patients with malignant pleural effusion underwent medical thoracoscopic talc poudrage pleurodesis between July 2005 and September 2007 in Peking University First Hospital.Results:There were 16 male and 11 female patients in the series,the average age being 65.2 years.All the patients had documented malignant pleural effusions,including 16 cases of adenocarcinoma,6 of malignant mesothelioma,2 of squamous cell carcinoma,1 of lymphoepithelioma-like carcinoma,1of small cell carcinoma and 1 of undifferentiated lung cancer.Thirty days after the procedures,complete successful pleurodesis was achieved in 22 cases,and partial successful in 4 cases.Pleurodesis was not successful in one case.Overall successful rate was 96.3%(26/27).The average duration of thoracic tubing was 6.85 days.Chest pain,fever and an increase in peripheral WBC after the procedure occurred in 19(70.4%,19/27),21(77.8%,21/27),and 12(44.4%,12/27)cases respectively.No respiratory failure occurred.Conclusion:Medical thoracoscopic talc poudrage pleurodesis is a safe and effective method for the treatment of malignant pleural effusion.

OBJECTIVETo study the effectiveness of pie-crusting technique in improving the stiff knee.

METHODSFrom February 2012 to December 2013, 13 patients with stiff knee were reviewed retrospectively. There were 6 males and 7 females, ranging in age from 39 to 70 years old (averaged, 55.6 years old). Of the 13 cases, 8 patients had stiffness following fracture (comminuted tibial plateau fracture in 4, femoral supracondylar fracture in 3 and patellar fracture in 1), 5 patients had TKA-related stiffness.

RESULTSA follow-up lasted 8 to 12 months (mean 10 months)in 13 cases. The mean maximum flexion increased from (37 ± 6)° preoperatively to (52 ± 7)° after arthrolysis, and (108 ± 7)° after pie-crusting. At the final follow-up, mean maximum flexion was (105 ± 6)°. According to Judet evaluation system, 10 patients got an excellent result and 3 good. No major complications, such as extensor lag, skin necrosis, deep infection, dislocation of the patella or recurrent stiffness were found.

CONCLUSIONThe percutaneous technique of pie-crusting is a simple, minimally invasive and effective treatment for knee stiffness.

A rapid resolution liquid chromatography coupled with quadrupole-time-of-flight mass spectrometric (RRLC-Q-TOF-MS) method was established and optimized for the analysis of pharmacokinetic behavior of ginsenoside Rb2 in rats by intravenous injection administration.The metabolism of ginsenosides Rb2 in vivo rat was also explored.In the experiment,Agilent SB C18 column was selected for the sample separation with 0.1％ aqueous formic acid solution as mobile phase (A) and acetonitrile as mobile phase (B) at a flow rate of 0.2 mL/min,and the injection volume was set to 5 μL.Q-TOF-MS was carried out in electron pray ionization (ESI) negative ion mode.The limit of quantification (LOQ,S/N =10) and limit of detection (LOD,S/N=3) were 0.10 and 0.08 μg/mL,respectively,and the linear range was 0.1-1.26 μg/mL.The experiment results showed that the concentration-time profile of ginsenoside Rb2 conformed to a two-compartment pharmacokinetic model after intravenous administration for rats.The mean plasma elimination half-lives were (23.58±1.10) min (t1/2α),(1306.55±147.23) min (t1/2β) for Rb2.By analyzing the urine of rats after intravenous administration and the fecal samples after oral administration of ginsenoside Rb2,it was found that the metabolites were M6,M2 (CY),F2,and C-K.

?AlM: To evaluate the clinical effects of excimer laser phototherapeutic keratectomy ( PTK) assisted by anterior segment optical coherence tomography ( OCT ) in the treatment of corneal anterior diseases.
?METHODS:There were 28 eyes of 15 patients who were diagnosed as corneal anterior diseases, on which excimer laser phototherapeutic keratectomy was performed from September 2012 to September 2013. The patients were checked up by anterior segment OCT before operation forauxiliarily judging types and depths of the disease to direct setting parameters such as cutting depths and diameters etc. in PTK. Follow-up of 6mo were included in this study. They were observed cornea condition, uncorrected visual acuity, spherical equivalent and haze at 6, 15d, and 1, 2, 3 and 6mo post-operatively.
?RESULTS: At postoperation, corneal condition of all patients were impoved more or less, that is, the outbreak was under control, or seizure frequency decreased obviously. There were no statistic differences between preoperation and postoperation on the changes of uncorrected visual acuity, spherical equivalent and haze (P>0. 05).
? CONCLUSlON: ln patients with corneal anterior diseases, excimer laser phototherapeutic keratectomy assisted by anterior segment OCT in the treatment of corneal anterior diseases can get rid of the lesion effectively and accurately and receive better treatment effect. But it is necessary to control the cutting depth avoiding postoperative hyperopia.

40 years old in 6 Uygur communities of Urumqi. The multi-phasic stratified cluster sampling method was adopted. Finally 191 men with high risk were selected as samples in the study and classified into two groups according to oral glucose tolerance test(OGTT)results, anthropometric and biochemical indicators. Results The prevalence of type 2 diabetes and IGR was 17.39% and 7.56% respecfively in the Uygur nationality. Waist-hip ratio, abdominal and waist circumference,the level of HbA1c and serum insulin of male diabetic patients were significantly higher than those of male IGR potieuts. But another four indicators of blood lipid and three indicators of renal function were not significantly different between two groups. Conclusion The indicators releted to abdominal obesity may be sensitive to diabetes and valuable to screen diabetic patients for giving effective health education and behavioral intervention in high risk population.
