AIM:To optimize the technical parameters indica-daisy dropping pill(Flos chrysanthemi indici) through controlling the influencing factors. METHODS:To take weight variation of pills,comprehensive quality and disintegration time limited as index,the above factors were observed by orthogonal test. RESULTS:Good technological parameters of indica-daisy dropping pill were as follows PEG6000∶PEG400=54∶6 as matrix,dimethicone as refrigerant.Temperature of drug fluids of 70 ℃,internal and external diameter of dropper within 6.2 mm and 9.0 mm,proportion of drug and matrix(1∶3),30 dropping per minute.The weight variation of pills was small,type quality was good and disintegration time limited was short.The water absorbability was smaller than that of granules. CONCLUSION:The finished products are of good quality and appropriate for mass production.

Objective To discuss the clinical value of f iberoptic ductoscopy in the diagnosis and treatment of breast diseases. Methods A total of 3 000 patients with mastalgia, breast mass or ni pple discharge received examinations by fiberoptic ductoscopy. Cytological exami nations were carried out in part of the patients after ductoscopy. Resu lts Of the 3 000 cases, there were 608 cases of intraductal space-occup ying lesions, 1 709 cases of obstructive galactophoritis, 350 cases of galactost asia, 24 cases of acute galactophoritis, 282 cases of simple mammarv duct ectasi a, and 27 cases of normal mammary ducts. Of 1 167 patients with nipple discharge , intraductal space-occupying lesions were clarified by ductoscopy in 585 cases (50%). Surgery was performed in 643 cases while intraductal interventional thera py was adopted in 2 365 cases. Conclusions Fiberoptic ductosco py may be used for the diagnosis and treatment of various breast diseases, not c onfined to nipple discharge.

In order to select high quality and suitable Bupleuri Radix varieties in Qingchuan, and establish a new comprehensive method to evaluation the quality of Bupleuri Radix, 12 characters of 14 samples were evaluated by DTOPSIS and grey related degree. The results showed that varieties No. 8 and No. 10 had high quality. DTOPSIS and grey related degree gave the uniformity result, and the biggest difference of value of Ci in DTOPSIS method was 46. 33% , but the biggest difference of the weighting correlation number( r (i)) in grey related degree was only 13.10%. The DTOPSIS combined with grey related degree can evaluate the quality of Bupleuri Radix comprehensively and objectively.

Objective To characterize the antibiotic resistance,homology and carbapenemase genotypes of imipenem resistant Acinetobac1ter baumannii isolated from our hospital,and analyze the clonal relatedness of the test strains.Methods Ninety five strains of imipenem resistant A.baumannii were isolated from August 2003 to December 2004 in the First Affiliated Hospital, College of Medicine,Zhejiang University.The MICs of 16 antimicrobial agents against these strains were determined by agar dilution and E-test method.The homology of these isolates was analyzed by pulse-field gel electrophoresis(PFGE).The coding gene of carbapenemases was amplified.PCR products were purified,cloned and sequenced.Plasmid DNA was extracted and purified.Conjugation and Southern blot were performed to locate the position of oxa 23 gene.Results The resistance rates to ampicillin-sulbactam and cefoperazone sulhactam were 67.9% and 30.2%.Polymyxin E had the lowest resistance rate of 17%. The resistance rate to other antimicrobial agents was higher than 90%.The 95 strains,isolated from 10 clinical units,were classified into 6 clones.Clones A and B were predominant clones.All strains produced carbapenemases which were confirmed as OXA 23 by PCR and sequencing analysis.No plasmid was extracted and conjugation was not successful.Southern bolt showed that oxa-23 gene was located on Apal-digested chromosomal segments about 220 kb and 200 kb in Clones A and B,re spectively.Conclusions OXA 23-producing A.baumannii has become one of the most important multi-resistant pathogens in our hospital.Clones A and B have widely spread in our hospital.Oxa-23 gene is located on chromosomal DNA.

A description of the contents, indexes, and method appropriateness for supervision and appraisal of the tobacco control management in hospitals, and an insight on the regularity and effectiveness of building tobacco-free hospitals. The dual indexes of intervention and outcome were ascertained from both dimensions of the management process and effect; in terms of methodology, the paper described the time appropriateness of the supervision focus, management effectiveness of the supervision and appraisal areas, priority of supervision objects, population appropriateness of the supervision and appraisal indexes, method appropriateness of the supervision, appraisal and penalty, as well as the conditional support for supervision and appraisal. It is pointed out that timely summary and appraisal, proper conditional support and circular work chain, can help consolidate tobacco control in hospitals.

Objective To explore the basic biological characteristics of lncRNA -uc.1 67,and its spatial dis-tribution,temporal expression pattern during the mouse embryonic development.Methods The UCSC genome browser of ENCODE was used to analyze preliminary bioinformatics of lncRNAs.Real -time (RT)-PCR was applied to detect the expression of uc.1 67 and neighboring genes in the embryonic mouse heart in different stages (P7.5,P1 1 .5,P1 4.5, P1 8.5).Dimethyl sulphoxide was used to induce P1 9 cell differentiation into the cardiomyocytes.RT -PCR was applied to detect the expression changes in uc.1 67 and neighboring genes on differential day 0,4,6,8 and 1 0.Results Full -length of human uc.167 was 201 bp,and human uc.167 was located in the genome 5q14.3 (chr5:88179623 -881 79824,GRCh37 /hg1 9).uc.1 67 mainly expressed in the ventricular muscle tissue.The expression of uc.1 67 was gradually decreased in the mouse embryonic heart development process(P7.5:1 .000 ±0.1 00,P1 1 .5:0.71 4 ±0.1 07, P1 4.5:0.393 ±0.043,P1 8.5:0.1 25 ±0.01 3),while the expression of its neighboring Mef2c gene was gradually in-creased(P7.5:1 .081 ±0.1 1 8,P1 1 .5:2.340 ±0.351 ,P1 4.5:3.958 ±0.542,P1 8.5:9.361 ±0.722),which showed an opposite trend.The expression of uc.1 67 during P1 9 cell differentiation into cardiomyocytes showed a an increase at first and then a decreasepattern,and the highest level expression of uc.1 67 was on differential day 4(d0:1 .071 ± 0.1 1 7,d4:4.71 4 ±0.501 ,d6:3.572 ±0.41 4,d8:2.550 ±0.31 4,d1 0:0.786 ±0.085).The expression of neigh-boring gene Mef2c was in an opposite trend(d0:1 .01 2 ±0.041 ,d4:0.353 ±0.037,d6:2.470 ±0.329,d8:6.706 ± 0.682,d1 0:7.765 ±0.705).Conclusions It is suggested that uc.1 67 may take part in the process of embryonic heart development and may play a role through negatively regulating its neighboring gene Mef2c.

The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

Chinese patent medicine with double identity was a special phenomenon, and many preparations not only were prescription drugs but also over the counter ( OTC) drugs, which brought a lot of trouble. Based on statistics of list of OTC medicines of CFDA, related varieties, route of administration and functions of these drugs were searched. The causes of insufficient were analyzed and the potential risk was investigated. To ensure the safety of drug usage for the patient, risk management system should be set up by improving the technical requirements for registration, improving the drug labels and manuals, playing the role of pharmacists in pharmacy services and raising awareness of doctor and patient for these drugs.
