OBJECTIVETo observe the changes in subgingival microflora before and after Er:YAG laser treatment on diabetic patients with periodontitis, and to compare with the subgingival microflora of chronic periodontitis.
METHODSSubgingival plaque of 13 pairs of teeth (26 sites) was selected from type 2 diabetic patients at pretreatment, one month post-treatment, and three months post-treatment. Subgingival plaque was also obtained from 11 cases of moderate to severe chronic periodontitis with similar severity of periodontitis. The DNA of the subgingival plaque samples was extracted. Whole bacterial 16S rDNA gene fragments separated by denaturing gradient gel electrophoresis. Specific DNA bands were then chosen for retrieval and sequencing.
RESULTSThe gene sequencing results of the special DNA bands of subgingival plaque samples show that the pathogenic bacteria of both diabetic periodontitis and simple chronic periodontitis were Prevotella intermedia and Tannerella forsythia, respectively. The composition of the subgingival microflora before and after laser treatment changed. Some DNA bands, including that of Tannerella forsythia, disappeared or weakened one month after treatment. A new strip appeared, which belonged to Actinomyces sp.
CONCLUSIONThe profiles of the subgingival microflora changed after treatment, and one month was indicated as an important stage. Er:YAG laser may have an important function in delaying microflora recolonization.

OBJECTIVE:To analysis the correlation between chrom aticity value and quality index of Atractylodis chinensis decoction piece powder stir-fired with bran ,and to determine its processing time. METHODS :The processed samples of 16 batches of A. chinensis decoction piece stir-fired with bran (S0-S15,S0 is the raw product of A. chinensis )were prepared ,and chromaticity values of all samples were determined ,such as lightness value (L*),yellow blue value (b*),red green value (a*). UPLC fingerprint of sample were analyzed ,and the contents of extract and volatile oil were also determined. Pearson correlation was used to analyze the correlation between the chromaticity value and quality index (relative peak area of each chromatographic peak in UPLC fingerprint ,water-soluble extract content ,alcohol-soluble extract content and volatile oil content ). Multivariate statistical analysis (principal component analysis ,cluster analysis ,partial least squares discriminant analysis )was carried out with chromaticity value and quality index ,and the processing time of A. chinensis decoction piece stir-fired with bran was determined by grey correlation method. RESULTS :In the process of bran frying ,with the extension of processing time ,L* and b* of decoction pieces powder decreased ,and a* increased first and then decreased ;relative areas of peak 1 and peak 2 increased first and then decreased,while relative areas of peak 3(5-hydroxymethyl furfural )increased,and the areas of the other peaks decreased. The content of the extract did not change significantly with time ,and the content of the volatile oil decreased. The results of correlation analysis showed that the relative peak area of peak 2-27,alcohol-soluble extract content and volatile oil content had a certain correlation with the chromaticity value ,while the relative peak area of peak 1 and water-soluble extract content had no linear correlation with the chromaticity value. Results of multivariate statistical analysis showed that the samples were divided into mild (S0-S5),excessive (S12-S15),moderate (S6-processing time of 18-33 min). The results of grey correlation method showed that the processing time of A. chinensis decoction piece stir-fired w ith bran should be controlled in the range of 18-24 min,and the optimal processing time was 18 min. CONCLUSIONS :There is a correlation between chromaticity value of A. chinensis decoction piece powder stir-fired with bran and the relative peak area of 27 chromatographic peaks ,and content of extract and volatile oil. It is suggested that the processing time should be 18 min.

OBJECTIVE:To establish the UPLC fingerprint of Polygonum cuspidatum ,and to determine the contents of four active ingredients and to provide reference for the quality evaluation of P. cuspidatum . METHODS :The determination was performed on Waters BEH C 18 column(100 mm×2.1 mm,1.7 μm)with mobile phase consisted of acetonitrile- 0.2% formic acid (gradient elution )at flow rate of 0.4 mL/min. The column temperature was 40 ℃,and detection wavelength was 290 nm. The sample size was 1 μL. The fingerprints were evaluated by similarity calculation,cluster analysis and orthogonal partial least square discriminant analysis (OPLS-DA). Using polydatin as internal standard ,relative calibration factors of resveratrol ,emodin-8-O- β-D-glucoside and emodin were determined to develop a method of QAMS. The contents of 4 above components in 15 batches of P. cuspidatum were calculated by relative calibration factors. The results of QAMS were compared with those of external standard. RESULTS:UPLC fingerprints of 15 batches of P. cuspidatum were established ,and 12 common peaks were confirmed. Five components were identified ,i.e. polydatin ,resveratrol,emodin-8-O-β-D-glucoside,emodin,emodin methyl ether. The fingerprint similarity of 15 batches of P. cuspidatum was in the range of 0.865-0.976. According to cluster analysis ,15 batches of P. cuspidatum were classified into 4 categories,showing certain regularity of origin. Seven markers were identified by OPLS-DA method. The order of difference significance was peak 7>emodin-8-O-β-D-glucoside>resveratrol>peak 8>polydatin>peak 1> peak 10. The relative deviation among the contents of resveratrol ,emodin-8-O-β-D-glucoside and emodin in 15 batches of P. cuspidatum determined by QAMS and external standard method was less than 5.0%,indicating that there was no significant difference between the two methods. CONCLUSIONS :UPLC fingerprint combined with QAMS method is convenient and reliable for the quality evaluation of P. cuspidatum ;the quality of P. cuspidatum produced in Chongqing and Anhui province is better.
