??OBJECTIVE To study the hepatotoxicity of Polygonum multiflorum on the basic of the bilirubin metabolism mediated by glucuronidation of UGT1A1 enzyme. METHODS Inspected the enzyme kinetic parameters after giving the rats Polygonum multiflorum extract orally(in vivo), and added the Polygonum multiflorum extract into the human liver microsome(rat liver microsome; human recombinant UGT1A1 enzyme) to test the hepatotoxicity using the bilirubin as UGT1A1 enzyme substrate, investigating the inhibition of the UGT1A1 enzyme(in vitro). Apparent inhibition constant Ki and enzyme kinetic parameters were used to evaluate the hepatotoxicity. RESULTS Polygonum multiflorum extract has a strong inhibiton to the UGT1A1 enzyme in all the three systems in vitro. All the type of inhibition is the competitive inhibition. While Polygonum multiflorum extract has a strong inhibiton to the UGT1A1 enzyme in vivo, but the type of inhibition is the uncompetitive inhibition.CONCLUSION The method we had established in our study provides a new idea and a new method to evaluate the hepatotoxicity and the safety of Chinese herbs. 相似文献

??OBJECTIVE To investigate the varieties and use of oral proprietary Chinese medicines in our hospital, analyze the problems existing in their labelings, and put forward suggestions to provide reference for clinical rational drug use. METHODS The properties of the 101 kinds of oral proprietary Chinese medicines in regard to the category, dosage form, essential drug, health care, OTC, and so on were summarized. Their labelings were collected to analyze the specification, usage and dosage, adverse reactions, contraindications and precautions, etc. RESULTS Among the 101 traditional Chinese medicines, 44.6% were developed specially for children. When counted by categories and dosage forms, the medicines for regulating spleen and stomach and granules accounted for the majority, respectively. Essential drugs, drugs belonging to the directory of insured drugs, and OTC drugs accounted for 19.8%, 70.4%, and 26.7%, respectively. It was found that 51.5% of the labelings included dosage information for different ages in detail, 59.4% did not state adverse reactions and contraindications clearly, and the smallest dosage suggested by 14.9% of the labelings were less than the smallest packaging dose. CONCLUSION Chinese patent medicines are widely used in pediatrics, but the information for children is still incomplete. The problems in the prescribing mainly include inappropriate selection of drugs and combination of medications. It was recommended that the relevant authorities carry out pediatric drug reevaluation and improve the labelings of pediatric drugs. 相似文献

??OBJECTIVE To investigate the clinical use of ornidazole injection in a wide patient population by the post-marketing hospital centralized monitoring method in order to regulate and guide its rational use, improve the drug specification, and provide a basis for the drug therapy. METHODS A prospective, multi-center, large sample hospital centralized monitoring method was adopted. Five sentinel hospitals in Hubei Province were selected, and hospitalized patients who received ornidazole injection treatment from July 1, 2015 to October 31, 2015 were observed. The basic information of the patients was recorded, as well as the drug use and adverse events, and then statistical analysis was made. RESULTS A total of 4396 cases were enrolled in this study, most of them were middle-aged female patients. Ornidazole injection was mainly used before surgeries to prevent infections and after surgeries for treatment of anaerobic infections, abdominal infections and pelvic infections. Irrational drug use existed in clinic, mainly concentrating at unreasonable dosing frequency, excessive dripping speed, and long duration of use. Eleven cases of adverse reactions were collected during the monitoring, indicating an incidence of adverse drug reactions of 2.5??, and most of the adverse drug reactions occurred within 30 min post drug administration. CONCLUSION The manufacturers should make further investigation on the dripping speed and quality standard of ornidazole injection to further improve the information in the package insert and regulate the clinical use. 相似文献

??OBJECTIVE To choose a PPK model of vancomycin most suitable for Chinese pediatric patients, in order to guide the dosage adjustment.METHODS Based on the database of PubMed and CNKI, all studies regarding vancomycin population pharmacokinetics were investigated and their basic information including PPK models was extracted. The data of Chinese pediatric patients who were administered vancomycin and received therapeutic drug monitoring(TDM) were introduced into the reported final PPK models, and the fitting was conducted by model fitting graphics. RESULTS Twelve vancomycin PPK studies during 1986-2014 were included. As judged by the correlation coefficient (R) and R-square(R2) between predicted concentration and measured concentration, the models 4 and 9 presented a relatively better fitting with the data of Chinese pediatric patients we collected. The VPC fitting demonstrated that number 1 model achieved the best fitting. However, because the limited data used in this study was based on irregular sampling time, so the VPC test results were difficult to be distinguished and could only be used as a secondary reference. On the other hand, NPDE has corresponding statistical test, and its evaluation ability for the model is not affected by the factors of the experimental design. NPDE analysis showed that one-compartment model was better than two-compartment model, and model 4 and model 9 achieved better fitting to the collected data than others.CONCLUSION The fitting effects of most reported vancomycin PPK models, except individual models, were poor for the TDM data of Chinese pediatric patients, therefore it is necessary to establish a vancomycin population pharmacokinetic model particularlly for Chinese pediatric patients, in order to guide dosage adjustment more accurately. 相似文献

??OBJECTIVE To evaluate the quality of now available clinical guidelines and consensus statements on type 2 diabetes. Based on this assessment, the comparison of guidelines and consensuses is made to give some suggestions on the METHODS of making these documents. METHODS PubMed, Embase, CNKI, Wanfang, SinoMed and guideline websites were systematically searched. Literatures were screened according to defined criteria for including. AGREE ?? was used to instrument assess the quality of the guidelines and consensuses. RESULTS The result showed that the quality of included guidelines is various, but the overall quality of guidelines is still higher than consensuses. Guidelines got high scores in scope and purpose domain and clarity of presentation domain, but low scores in rigor of development domain and applicability domain. Consensus statements got low scores in all 6 domains. CONCLUSION The main reason for the difference is consensuses have poor methodology. Rapid advice guidelines were suggested as an alternative for consensus statements. 相似文献

??OBJECTIVE To establish an interferon-resistant hepatitis B virus cell model and provide experimental basis for further investigating the mechanism of HBV resistance to interferon. METHODS HepG2.2.15 was continuously grown in the presence of 10,30,50 and 70 u??mL-1 of interferon ??-2b for up to 48 weeks. The HepG2.2.15/IFN??-2b cell model was constructed after 48 weeks of induction. The cells were treated with the best-effect concentration. Then, the levels of HBsAg, HBeAg, and HBV DNA in the supernatant of cell culture medium before and after the treatment were compared. RESULTS After stimulation with low concentrations of IFN??-2b for 12 weeks, the 50 u??mL-1 group showed significant resistance to the best-effect concentration of IFN??-2b. Compared with the levels before stimulation, the inhibition rate on HBsAg, HBeAg, and HBV DNA decreased by 25.48%, 8.40%, and 15.43%, respectively, suggesting that 50 u??mL-1 was the best-stimulation concentration. After stimulated with 50 u??mL-1 IFN??-2b for 12-48 weeks, the results showed that the inhibition rate on HBsAg, HBeAg, and HBV DNA after 36 weeks was the most significant. CONCLUSION Continuous induction with 50 u??mL-1 IFN??-2b for 36 weeks could most easily induce drug resistance in HepG2.2.15 cells. 相似文献

??OBJECTIVE To provide basis for rational use of biapenem in elderly patients through Monte Carlo simulation. METHODS A total of 294 strains from five species of Enterobacteriaceae were collected. The MICs of biapenem against the bacteria were measured by double broth dilution method. Six therapeutic regimens (300 mg q24h; 300 mg q12h; 300 mg q8h; 300 mg q6h; 600 mg q24h; 600 mg q12h) were simulated by using Monte Carlo simulation, then the probability of target attainment (PTA) and cumulative fraction of response (CFR) were calculated. RESULTS In patients at 65-74 years old, only the CFR of 300 mg q24h regimen was ??90% (73.69%) for E. coli; only the CFRs of 300 mg and 600 mg q24h treatment regimens were ??90% (64.98%,82.51%;63.83%,79.82%;63.11%,78.7%, respectively) for K. pneumonia, E. aerogenes and E. cloacae; in patients ??75 years old, all of the regimens had PTAs ??90% for E. coli and E. aerogenes; only the 300 mg q24h regimen had CFRs??90% (89.39% and 88.98%) for K. pneumonia and E. cloacae; for E. aerogenes, all the regimens had CFRs ??90%. CONCLUSION It is suggested that different regimens can be used for target therapy of biapenem on the basis of MICs, while frequency of q12h or higher can be used for experiential therapy of enterobacteriaceae infection in old people in our hospital. Other antimicrobial agents should be chosen for treatment of E. aerogenes. 相似文献

??OBJECTIVE To prepare nano-micelles with amphiphilic self-assembly poly (ethylene glycol)-co-poly (propylene sulfide) (PEG-PPS) copolymer as carrier to study the release characteristics of tilianin and investigate its activity to against H9c2 cell apoptosis in vitro. METHODS An amphiphilic diblock PEG-PPS polymer was used as a carrier material to prepare the tilianin-containing nano-micelles by solvent evaporation. The morphology, particle size and distribution, drug loading and encapsulation rate and in vitro drug release behavior were characterized, H9c2 rat myocardial cell injury model was established by hypoxia/reoxygenation process. Using propranolol (Pro) as a positive control, the morphology of injured cardiomyocytes was observed by microscope. Cell proliferation and cell apoptosis was detected to evaluate the protective effect of blank micelles, tilianin and tilianin loaded nano-micelles on H9c2 cells induced by hypoxia/reoxygenation. RESULTS Tilianin-loaded nano-micelles was spherical with uniform particle size distribution. The drug loading was 3.82%. The average particle diameter of tilianin-loaded nano-micelles was 137 nm, polydispersity coefficient was 0.162 and the encapsulation efficiency was 91.45%. In vitro drug release studies showed that there was no drug-induced burst release of tilianin-containing nano-micelles and sustained release characteristics, and the presence of hydrogen peroxide significantly promoted the release of tilianin from the nano-micelles. In vitro cytotoxicity experiments showed that when the concentration of tilianin 5 ??g??mL-1, the cell viability of tilianin-loaded nano-micelles was significantly higher than the corresponding concentration of tilianin and PEG-PPS polymer nano-micelles. In vitro anti-apoptotic activity experiments show that tilianin-loaded nano-micelles on H9c2 cell apoptosis induced by hypoxia-reoxygenation have a significant inhibitory effect and was provided inhibition of apoptosis with propranolol. CONCLUSION Tilianin-loaded nano-micelles have uniform particle size and distribution, sustained release and oxidation characteristics, has a significant protective and apoptosis-inhibiting effect on H9c2 cell injury induced by hypoxia-reoxygenation, which can be used as a promising drug delivery system for the treatment of myocardial ischemia-reperfusion injury. 相似文献

??Topical ocular medication is commonly used for eye diseases treatment.In view of low bioavailability and poor efficacy of traditional ocular preparations,the development of novel ocular drug delivery systems has become a great challenge in pharmaceutics.In recent years, nano preparations have been widely used for ocular drug delivery systems. At present, several nanocarriers, such as polymeric micelles, nanoparticles, nanosuspension, liposomes, emulsion, and dendritic polymers have been developed for ocular drug delivery.There are some other new dosage forms, such as in-situ gelling systems, implants, contact lenses, and microneedles are also under continuous research. The aim of development of these new dosage forms is to improve the drugs' ocular bioavailability and therapeutic effects.In this paper,the development in these areas in recent years are reviewed in order to provide reference for the development of new ocular drug delivery systems. 相似文献

??OBJECTIVE To investigate and study the 2012 edition of National Essential Medicine List chemical medicines and biological products off-label drug use in pediatrics, analyze the causes of off-label use of medications, provide the suggestion for off-label drug use in pediatrics. METHODS To adopt questionnaire survey in different regions of the 10 third-grade class-A children??s hospital off-label use of medications in 2012 edition of National Essential Medicine List chemical medicines and biological products of 309 types which excluded obstetrics and gynecology medication, family planning administration and national immunization programs with vaccine from 317 types. Excel 2007 software is used for data calculation and statistical analysis. RESULTS ??20 categories, 22 dosage forms, which accounted for 80% of all drug categories are involved in off-label use of medications in 2012 edition of National Essential Medicine List. ?? Lack of children??s dosage (62.95%) is mainly responsible for off-label of drugs. Off-label use of medications mainly manifest in off-labeling with pediatric indications (85.94%), of which labeling with pharmacological action without indication (45.63%) is the main type, and off-labeling with route of medication (66.96%).?? 2013 edition of Chinese National Formulary(Chemical and Biological Products for Children)and 2010 edition of Chinese Pharmacopoeia of Clinical Medication Information are the main evidence for off-label drug use, account for 34.60% of the total number of cases. ?? 147 types of medicines which involved in off-label use are searched in a database named Micromedex. Indications have been approved by the the US Food and Drug Administration (FDA) or not which labeling with children??s dosage account for 27.10% of the total number of indications. CONCLUSION Off-label drug use in the 2012 edition of National Essential Medicine List is an important public health issue for children. It reflects the lack of labeling with pediatric information. It is suggested that joint efforts should be paid by departments concerned and more support be provided to further improve the policy for children??s medication.
