OBJECTIVE:To enrich the identification diversity of traditional Chinese medicine(TCM),and provide theoretical guidance for the quality evaluation of TCM. METHODS:According to literature references and traditional identification experienc-es,characteristics including medicinal shape,size,color and lustre,surface,texture,section,odor and other aspects were identi-fied by sense organs such as eyes,hands,nose and mouth. The vivid traditional identification term were obtained through systemat-ic summarization in order to explore the internal relationship with pharmaceutical botany. RESULTS&CONCLUSIONS:As the sim-plest identification method,traditional identification method can rapidly identify the species and quality of TCM,evaluate the quali-ty,and has great significance to solve the security issues of clinical medication and health care in daily life. There was a correlation between the traditional identification and botanical research,which could be able to provide theoretical guidance to characters identi-fication and quality evaluation of TCM.

OBJECTIVEThis review aims to identify the dimensional structure of the shortened dentine hypersensitivity experience questionnaire (DHEQ-15) using confirmatory factor analysis (CFA).

METHODSThe Chinese language version of DHEQ-15 was applied to 210 patients with dentine hypersensitivity aged 18-70 years old. The three-dimensional construct was confirmed by CFA.

RESULTSAll the questionnaires were fully completed. The item "Because of the sensations, I take longer to finish a meal than others" was the most frequently reported by the parents. The modified three-factor model is suitable for the data. The chi-square fit statistics/degree of freedom was 2.213, the goodness-of-fit index was 0.905, the adjusted goodness-of-fit index was 0.872, the normed fit index was 0.845, the incremental fit index was 0.962, the Tucker-Lewis index was 0.969, the comparative fit index was 0.977, and the root mean square error of approximation was 0.068.

CONCLUSIONSOur findings generally support the three-dimensional construct of the DHEQ-15. Thus, DHEQ-15 can be used as a valid instrument in patients with dentine hypersensitivity in China.

Objective To investigate the relationship between nonalcoholic fatty liver disease (NAFLD) and benign prostatic hyperplasia (BPH) in elderly patients.Methods 50 elderly BPH men with NAFLD were enrolled in this study,while 30 age-matched BPH men without NAFLD were selected as the control group.Prostate volume (PV),body mass index (BMI),triglycerides (TG),fasting blood glucose (FBG),fasting plasma insulin (FINS) and homeostasis model of assessment for insulin resistanceindex (HOMA-IR) were compared between the two groups,and correlations of PV with FINS and HOMA-IR were analyzed in the NAFLD patients.Results The PV level was significantly higher in NAFLD patients than in control group [(48.2±16.3) ml vs.(33.2± 11.5) ml,P＜0.01].The incidence of severe BPH was higher in NAFLD group than in control group (42.2％ vs.13.3％,P＜0.05).BMI,TG,FBG,FINS and HOMA IR were higher in NAFLD group than in the control group (all P＜0.01).The PV was positively correlated with FINS and HOMA-IR levels in elderly NAFLD patients (r=0.814,0.601,respectively,both P＜ 0.01).Conclusions NAFLD is closely associated with BPH in elderly males,and NAFLD may be one of the risk factors for BPH.

The rapid development of stomatology is improving the standard of talent quality and skills gradually,so the innovation of cultivation patterns of the stomatology students is imperative.West China College of Stomatology in Sichuan University is practicing the innovation of cultivation system of stomatological talents by establishing the new teaching and learning plan,adjusting the course system,strengthening the teaching materials construction,and adjusting the evaluation index and so on.The goal of the innovation of cultivation patterns is to foster the stomatological talents which have profound cultural atmosphere,the solid professional knowledge,strong innovative consciousness,and broad international vision.

To observe the clinical results of innercapsular phacoemulsification with primary intraocular lens ( lOL ) implantation in the treatment of lens dislocation.METHODS: A total of 23 cases ( 23 eyes ) of lens dislocation ( lla and llb ) were underwent innercapsular phacoemulsification combined with primary lOL implantation. lOL implantation were underwent during operation, the complications of intraoperative and postoperative, postoperative vision, intraocular pressure ( lOP ) , corneal endothelial cell, lOL location were analyzed.RESULTS: The operations were successfully completed for all patients in accordance with the pre - surgery program; lens nucleus or its fragments did not crash into the vitreous cavity; 20 cases of corneal edema and 17 cases of lOP presented at the first day after surgery, the deviation or displacement of lOL and serious complications such as retinal detachment were not appeared. At the first week postoperation, the average lOP was 15. 81 ± 2. 10mmHg, with statistically significant differences when compared with the preoperative ( P<0. 01 ) , the visual acuity in all eases increased, with statistically significant differences when compared with the preoperative ( P < 0. 01 ). Corneal endothelial cell density and percentage of hexagonal cells decreased, the variation coefficient increased in first week of postoperative, with no statistically significant differences when compared with the preoperative (P>0. 05) CONCLUSlON: lnnercapsular phacoemulsification combined with primary lOL implantation in the treatment of the whole lens dislocation (‖a and ‖b ) can restore function in patients with diplopia and control lOP effectively, reduce corneal endothelial cell damage, which is an effective method to treat the whole traumatic lens dislocation.

Low frequency sensorineural deafness is a common subtype of idiopathic sudden deafness. Certain patients suffered recurrent attacks without vertigo, much alike Meniere's disease. Few of them developed into definite Meniere's disease during long-term follow-up in many clinical studies. Although the pathophysiology of recurrent low frequency deafness is yet unknown, the desease is considered associated with early state of endolymphatic hydrops or migraine. Otologists shall be aware of its clinical course and careful explanation is necessary at time of initial informed consent.

OBJECTIVE:To compare the contents of loganic acid,swertiamarin,6′-O-β-D-glucosyl gentiopicroside,gentiopi-croside,sweroside,isoorientin and isovitexin in wild and cultivated Gentiana officinalis,and to provide basis for rational use of G. officinalis. METHODS:UPLC method was adopted. The separation was performed on ACQUITY UPLC? BEH C18 column (50 mm × 2.1 mm,1.7 μm) with mobile phase consisted of methanol-0.04% phosphoric acid (gradient elution) at the flow rate of 0.3 ml/min. The detection wavelength was set at 242 nm,and column temperature was 30 ℃. RESULTS:For loganic acid,swertiama-rin,6′-O-β- D-glucosyl gentiopicroside,gentiopicroside,sweroside,isoorientin and isovitexin,a good linearity was obtained in the range of 2.1-537.1 μg,1.05-270 μg,0.92-236 μg,11.1-2 830 μg,0.75-192 μg,0.167-102 μg,0.216-52.80 μg(r≥0.999 5), respectively. Their average recoveries were 97.72%-99.84%(RSD≤3.39%,n=6). The contents of loganic acid,swertiamarin, 6′-O-β-D-glucosyl gentiopicroside,gentiopicroside,sweroside and isoorientin in the wild sample were higher than in the cultivat-ed;the content of isovitexin was lower than the cultivated,but there was no statistical significance(P>0.05). The sum of gentiopi-croside and loganin acid content were all higher than 2.5% in both wild and cultivated samples,and met the requirements of 2015 edition of Chinese Pharmacopoeia(first part). CONCLUSIONS:The content difference of 7 indicative constituents in wild and cul-tivated G. officinalis is not statistically significant,and the indicative constituents of the pharmacopoeia is qualified.

Objective To investigate the circulation and use of Akebiae Caulis and Clematidis Armandii Caulis;To provide references for clinical safe medication. Methods Literature review, field survey and telephone interview were used to conduct the investigation. Results ① The market currency of the Akebiae Caulis and Clematidis Armandii Caulis was very confused, and the mainly medicinal materials on the market were Clematidis Armandii Caulis. ② The majority used medicinal materials were Clematidis Armandii Caulis, and Akebiae Caulis was rarely used. ③ The Chinese Pharmacopoeia collected Akebiae Caulis and Clematidis Armandii Caulis separately, but there was phenomenon of using Clematidis Armandii Caulis replacing of Akebiae Caulis. Conclusion Market of Akebiae Caulis is shrinking; the phenomenon of using Clematidis Armandii Caulis to replace Akebiae Caulis widespread in clinic. There are differences in the efficacy of Akebiae Caulis and Clematidis Armandii Caulis, so they should be distinguished and cannot be used to mix or substitute.
