ABSTRACT
OBJECTIVE:To compare the composition changes of Aurantii fructus before and after fermentation processing and optimize its fermentation processing technology. METHODS:UPLC was conducted to compare the raw and fermentation processed products of same batch of Aurantii fructus,and ensure the chromatographic peaks after fermentation processing. Using peak areas of 4 chromatographic peaks and mildew characteristics of samples as index,fermentation temperature,humidity and time as factor, L9(34)orthogonal test was designed to optimize the fermentation processing technology,and verified it. RESULTS:After fermenta-tion processing,Aurantii fructus obviously showed 2 new monosaccharide glycosides components;the optimized fermentation tech-nology was as follows as fermentation temperature of 30 ℃,humidity of 70% and time of 7 d;verification test results showed RSD of each indicator of decoction pieces prepared by optimized fermentation technology in 3 tests were lower than 2.0%(n=3). CONCLUSIONS:Fermentation processing may lead obvious chemical composition changes in Aurantii fructus;the optimized fer-mentation processing technology can increase the contents of characteristic peaks.
ABSTRACT
This review introduced the application of near infrared spectroscopy (NIRS) in the identification of species, production area and processing method as well as quality evaluation of Chinese materia medica (CMM). By comparing with other authentication methods of CMM, the NIRS technology showed great advantages in exclusive identification of CMM, both identification and quality evaluation of CMM as well as identification of famous-region medicinal material. Finally, the future direction of the authentication of CMM by NIRS technology was suggested.

Objective To study the efficacy of different anti-adhesion agents used in preventing tubal obstruction after recanalization.Methods Five hundred and eight patients with tubal obstruction were divided into 245 cases in control group,108 cases in chitosan group;113 cases in sodium hyaluronate group and 42 cases in lipiodol group.The patients in control group were injected with anti-inflammation agents after recanalizatian,while other groups were injected with chitosan,sodium hyaluronate or lipiodol at dose of 2-3 ml in every therapeutic group.The rate of location of tubal obstruction and tubal recanalization were recorded during operation.Then patients in every group were followed up on tubal patency after 3 months,and pregnancy rate after 12 months.Results Among 1016 fallopian tubes in 508 patients,there were 330 tubes occlusion at isthmus portion and 563 tubes occlusion at interstitial portion of fallopian tube.Thirtyseven fallopian tubes were ablated because of ectopic pregnancy,86 fallopian tubes were unobstructed.(1)The recanalization rate were 95.7% (179/187) in chitosan group,97.9% (191/195) in sodium hyaluronate group,98.7% (75/76) in lipiodol group and 97.7% (425/435) in control group,which did not show statistical difference (P＞0.05).(2) The rates of tubal patency after 3 months of 91.7% (99/108) in chitosan group and 88.5% (100/113) in sodium hyaluronate group were significantly higher than 71.4% (30/42) in lipiodol group and 74.3% (182/245) in control group (P ＜0.05).(3)The rates of intrauterine pregnancy after 12 months were 48.1% (52/108) in chitosan group and 41.6% (47/113) in sodium hyaluronate group,which were significantly higher than 23.8% (10/42) in lipiodol group and 24.1% (59/245) in control group (P ＜ 0.05).Conclusion Chitosan and sodium hyaluronate could be effective to prevent tubal obstruction after interventional recanalization and increase pregnancy rate.
ABSTRACT
Object To define the molecular characters of differentiating Bupleurum chinense DC., B. scorzonerifolium Willd. from their allied species B. marginatum Wall. ex DC., B. smithii Wolff var. parvifolium Shan et Y.Li. and B. longiradiatum Turoz. Methods General DNA was isolated from fresh leaves of Bupleurum L. species by CTAB. The random amplified polymorphic DNA (RAPD) was used to identify them. Results Five Bupleurum L. species can be identified by primer OPA-1(5'-CAGGCCCTTC-3'), OPD-8 (5'-GTGTGCCCCA-3'), OPD-11 (5'-AGCGCCATTG-3'). Conclusion The method of RAPD can be used to identify the Bupleurum L. species and its allied species.
