OBJECTIVE:To investigate the characteristics and regularity of ADR induced by Iobitridol injection,and to provide reference for clinical drug use.METHODS:In retrospective study,the information of 72 patients suffering from ADR induced by Iobitridol injection were collected from our hospital during Jul.2015 to Jul.2016,and then statistical analysis was conducted in respects of age,gender,primary disease,organs/system involved in ADR,clinical manifestations,relationship evaluation and degree,occurrence time,outcomes,etc.RESULTS:Among 72 cases of ADR,the number of female was about twice of that in male.The age mainly distributed in the range of 50 to 80 years old (80.56％).ADR mainly occurred in skin and its appendants (30.57％),followed by systemic reactions (22.93％) and circulatory system (21.66％).ADR occurred within 20 min after medication (38.89％).58.33％ of ADR patients were cured,and 41.67％ were recovered.CONCLUSIONS:During the application of Io bitridol injection,a detailed understanding should be obtained about the patient's condition,medical history and the results of the examinations.Medical staff should inform the patient of the possible allergic symptoms,and do a good emergency preparation.

Objective To study the quality control of yinpian of Isatis Root.Methods Optical microscope was used to identify the microscopic features,TLC was adopted to identify the arginine in Isatis Root,and HPIC-ELSD was used to detect the quality of arginine.Results and Conclusion There is no difference between yinpian and crude powder of Isatis Root.Arginine can be detected bv TLC.The moisture contents.the total ash contents and the acid-insoluble ash contents in the yinpian should be less than 9.0%,10.0%,and 2.0% respectively;while the alcohol-soluble extractive contents and the contents of arginine in Isatis Root should be more than 25.0% and 2.01% respectively.

OBJECTIVE:To design intermittent intravenous drip dose regimen of antibiotics. METHODS: The pharmacokinetic data were computed using the multidoses function method taking cefazolin,ceftriaxone and amikacin as examples. Then computation program was programmed using Excel software based on pharmacokinetic parameters combined with pharmacodynamic parameters to design rational dosage regimen. RESULTS: The bactericidal effect of time-dependent antibiotics was chiefly dependent on the time during which the drug blood concentration was higher than minimal inhibitory concentration(MIC).For those antibacterials with short elimination half life(t1/2)in plasma,the best regimen was to give patients the med-icine in a small average divided dose or continuous medication. For those with(t1/2) greater than 12～24 h,single dose admin-istration was advisable. For concentration-dependent antibiotics,the best PK/PD parameters for optimal clinical antibiotic effect were Cmax/ MIC,and which should be administered in single time (daily dose). CONCLUSION: PK/PD parameters -based intermittent intravenous drip dosage regimen of antibiotics designed by means of Excel function is simple,reliable and intuitionistic.

At present the study of Marine antineoplastic drugs has already become the focus of concern around the world, Marine natural products has become an important source of clinical anti-cancer drugs. Ecteinascidin-743 from the Caribbean sea squirts Ecteinascidia turbinata extraction have been the ocean alkaloid, antitumor activity is significantly higher than the current widely used clinical antitumor drugs, inhibit a wide variety of tumor cell activity such as leukemia, ovarian cancer, soft tissue sarcoma, melanoma, cervical cancer, breast cancer, colorectal cancer, kidney cancer, prostate cancer, lung cancer and non-small cell lung cancer and other tumor cells, is the first successful application to the oceans, clinical antitumor drugs. In this paper, the drug synthesis, pharmacological and clinical research progress were reviewed.

OBJECTIVE:To provide reference for the exploration of training model of clinical pharmacist in according with special condition of our country.METHODS:The manner of clinical pharmacist training and pharmaceutical care in the training base of our hospital were analyzed,and training contents and pattern were summarized.RESULTS&CONCLUSIONS:It needs to improve the capacity of students during clinical pharmacist training in respect of theory and practice.Moreover,strict access system and examination should be strengthened,teaching and studying should complement each other.

OBJECTIVE:To investigate the curative effect and economics of prostaglandins drugs in the treatment of glauco-ma,and to provide reference for clinical medication. METHODS:In retrospective study,a total of 790 glaucoma patients were di-vided into latanoprost group(62 cases),travoprost group(356 cases)and bimatoprost group(372 cases)according to therapy regi-men. They were given relevant medicine. Total effective rate of 3 groups were calculated,and the cost-minimization method was used for pharmacoeconomics evaluation. RESULTS:The total effective rate of 3 groups were 87.10%,84.27%,76.08% respective-ly,without statistical significance(P>0.05). The cost of them were 208.00 yuan,225.00 yuan and 173.00 yuan,and that of bima-toprost group was the lowest. The results of sensitivity analysis was in line with that of cost-minimization analysis. CONCLU-SIONS:For glaucoma,bimatoprost is more economical than latanoprost and travoprost.

AIM　To study the activation of choline on M3-R in heart and observe the hemodynamic changes of rat and rabbit. METHODS　A cardiac catheter was inserted into the left ventricular cavity via the right carotid artery, then the HR, LVSP, LVEDP, and ±dp/dt were measured using a polygraph system. RESULTS　Choline was shown to decrease the hemodynamic assessments, such as HR, +dp/dt, LVSP and LVEDP. while the M3-R antagonist 4-DAMP (4-diphenylacetoxy-N-methylpiperidine-methiodide) showed little effect on these assessments. It was found to reverse the hemodynamic effects of choline. CONCLUSION M3 receptor agonist can produce negative inotropic and chronotropic effects on the heart of rat and rabbit.

Exposure to particulate matter 2.5 (PM2.5) potentially triggers airway inflammation by activating nuclear factor-κB (NF-κB). Sirtuin 2 (SIRT2) is a key modulator in inflammation. However, the function and specific mechanisms of SIRT2 in PM2.5-induced airway inflammation are largely understudied. Therefore, this work investigated the mechanisms of SIRT2 in regulating the phosphorylation and acetylation of p65 influenced by PM2.5-induced airway inflammation and bronchial hyperresponsiveness. Results revealed that PM2.5 exposure lowered the expression and activity of SIRT2 in bronchial tissues. Subsequently, SIRT2 impairment promoted the phosphorylation and acetylation of p65 and activated the NF-κB signaling pathway. The activation of p65 triggered airway inflammation, increment of mucus secretion by goblet cells, and acceleration of tracheal stenosis. Meanwhile, p65 phosphorylation and acetylation, airway inflammation, and bronchial hyperresponsiveness were deteriorated in SIRT2 knockout mice exposed to PM2.5. Triptolide (a specific p65 inhibitor) reversed p65 activation and ameliorated PM2.5-induced airway inflammation and bronchial hyperresponsiveness. Our findings provide novel insights into the molecular mechanisms underlying the toxicity of PM2.5 exposure. Triptolide inhibition of p65 phosphorylation and acetylation could be an effective therapeutic approach in averting PM2.5-induced airway inflammation and bronchial hyperresponsiveness.
