Object To observe the differences of Isodon amethystoides (Benth.) C. Y. Wu et Hsuan, I. nervosa (Hemsl) Kudo and I. macrocalyx (Dunn) Kudo from different regions in their UV spectra, to make the applicability of the method of Detrended Correspondence Analysis (DCA) clear in the comparison of Chinese medicinal materials based on the UV spectra. Methods The UV spectra of the 15 samples of I. amethystoides, I. nervosa and I. macrocalyx from different regions and organs were obtained, based on the indices of wavenumber absorbance, the differences of 15 UV spectra were compared by DCA. Results(1) the UV spectra of I. amthystoides from different regions were very different; (2) the samples of I. macrocalyx (or I. nervosa) from the same region were rather similar in their UV spectra; (3) there were resemblances among I. nervosa, I. macrocalyx and I. amethystoides in their UV spectra.; (4) the difference of UV spectra between the stems and leaves were obvious. Conclusion The above results indicate: (1) the medicinal effects of I. amethystoides from different regions may be very different; (2) the stems and leaves of I. amethystoides are of different medical effects; (3) I. macrocalyx and I. nervosa could be considered as the substitutes of I. amethystoides. It is practical to apply DCA on the basis of UV spectra to compare the chemical differences of plant samples.

Objective To investigate effect of antibiotic standardized management on prophylactic application of antimicrobial agents in type I andⅡ incision.Methods The hospital implemented the rule of Clinical Use of Antibiotics Management Approach and 2013 National Clinical Use of Antibiotics Special Rectification Program of Activities, 200 clinical surgery effective surgical cases before implementation and 250 clinical surgical effective surgical cases after implementation were selected.The thyroid surgery and hernia repair surgery were chosen as type I incision, and cesarean section were chosen as type Ⅱ incision.The basic data of surgery classification and antibacterials use were collected, then the antibiotics utilization ratio, the timing of administration of antibiotics, postoperative use of antibiotics time and combination therapy were compared between pre-implementation and post-implementation.Results The condition in accordance with applicable standards of antibiotics post-implementation: the antibiotics utilization ratio of thyroid surgery was 0 and post-operative stopping time was within one day.There was no combination therapy of three types surgery ( thyroid surgery, hernia repair surgery and cesarean section).The application of antimicrobial agents improved significantly but did not reach criteria:antibiotics utilization ratio of hernia repair surgery was 62.00%, which was higher than the criterion of 30% in antibiotic standardized management.Withdrawal time of antimicrobial agents post-operation in hernia repair surgery was (1.01 ±0.15)d which was above the standard of 1d and in cesarean section was (2.02 ±0.25)d which was above the standard of 2d.Conclusion The hospital strengthens management and standardizd regulation of antimicrobial drugs could facilitate standardization in type I and Ⅱ incision, and improve the quality of hospital medication administration of antibiotics.
