OBJECTIVE:To provide reference for improving pharmaceutical consultations and the quality of pharmaceutical care. METHODS:The records of pharmaceutical consultations were collected from medication consultation center of Huilong-guan district in our hospital during Jan. 2014-Dec. 2016,and then summarized in terms of consultants composition,consultation form,consulting contents and drugs consulted,while Pareto Diagram was used to analyze the main and minor factors of consult-ing contents. RESULTS:The medication consultation center provided pharmaceutical consultations 20353 cases during 2014-2016. Main consultants were patients (20039 cases,98.5%). A total of 6307 persons were involved,mostly female (3646 persons,57.8%). Face to face was the most common consulting method (19440 cases,95.5%). There were 13 types of consulting contents,among which usage and dosage and guidance for special formulation use were the main factors,including 10392 cases (51.1%) and 3844 cases (18.9%). Among 20353 cases of pharmaceutical consultations,18874 cases of in-volved drugs,and involved 11 categories,mostly respiratory drugs (11756 cases,62.3%). CONCLUSIONS:Usage and dos-age and guidance for special formulation use are the main contents of pharmaceutical consultations in the hospital district. The services of pharmaceutical consultations for patients,physicians and nurses provided by pharmacists can solve the questions on medications,and can promote rational drug use in clinic.

Heparin and low molecular weight heparin have been widely used in clinical therapy as anticoagulants in cardiovascular disease and in hemodialysis. Crude heparin is usually prepared from porcine intestinal mucosa. Purified heparin is a mixture of polysaccharides consisting mainly of repeating GlcNS(6S)-IdoA2S disaccharides and other disaccharides with different GlcNAc/GlcNS±3S±6S-GlcA/IdoA±2S residues. Heparin injections are drugs prepared from heparin active pharmaceutical ingredient ( API ) that is prepared from crude heparin. Low molecular weight heparins are dominant heparin-based drugs used clinically, which are prepared by degrading heparin into smaller sizes. As a result, low molecular weight heparins are sharing the same major disaccharides but have different reducing and non-reducing ends. In current study, we focused on the disaccharide compositional analysis of clinically used heparin and heparin-based drugs. HeparinaseⅠ,II, and Ⅲ were used to degrade all heparin and heparin-based drugs including heparin sodium injection, Enoxaparin sodium injection, Nadroparin calcium injection, Dalteparin sodium injection, Fondaparinux sodium into disaccharides. All the degraded products were analyzed by strong anion high perforance liquid chromatography ( SAX-HPLC) coupled with an UV-detector. Commercially available unsaturated disaccharide standards were then used for structral identification. Furthermore, unusual disaccharides present in Nadroparin, Dalteparin, and Fondaparinux were confirmed by reversed-phase ion pair HPLC coupled with mass spectrometry. The developed method produced detailed structural information, which should be useful for quality control of heparin and heparin-based drugs.

A method was developed to assay α-Hydroxyltriazolam and α-Hydroxyalprazolam,　which are the major metabolites of triazolam and alprazolam respectively,in human urine.　After addition of 2-hydroxyflurazepam　(interal standard) and hydrolysis with β-glucuronidase, the hydroxy-metabolites were extracted with hexane-dichloromethane (1∶1) at pH　10.8, then were derivated with (BSTFA). The analysis was performed on a HP-5 capillary column with electron-capture detector.The detection limits of analysis in urine were about 1μg/L.The method was successfully applied to urine specimens collected from healthy human volunteers who ingested 0.5 mg of triazolam or 0.8 mg alprazolam. The method was enough sensitive to assay urine specimen excreted at 24 h by volunteers after taking the medicine.

Objective To explore the clinicopathological characteristics of lupus nephritis (LN) with antinucleosome antibody (AnuA).Methods Data of 481 patients with biopsy-proven LN in the First Affiliated Hospital of Zhengzhou University from 2004 to 2011 were analyzed retrospectively.The patients were divided into two groups:AnuA-positive group (76 patients) and AnuA-negative group (405 patients).The clinical manifestations,laboratory examinations,histopathologic classes of LN,disease activity measured by SLE disease activity index (SLEDAI) of two groups were investigated and compared.Results There were 15 male patients in positive group (15/76,19.74％) with mean age of (27.99±10.88) years and 45 patients in negative group (45/405,11.11％) with mean age of (31.15±12.15) years respectively,which showed that male patients were more common in positive group (P＜0.05).Incidences of oral ulcer,fever,anemia,low complement and positive anti-dsDNA antibody were higher in positive group (P＜0.05).Percentage of diffuse proliferative lupus nephritis (class Ⅳ ) and pathological activity index (AI) in positive group were higher compared to negative group (all P＜0.05),while no significant differences of other pathological types,chronic index (CI) and SLEDAI were found between two groups.Conclusion LN patients with positive AnuA have special clinicopathological characteristics and AnuA may be used as a promising biomarker for the proliferative LN.

Hormones and epigenetic characteristics in a patient with clinically diagnosed adrenal hypoplasia congenita (AHC) were analyzed. Results indicated that plasma ACTH increased, while cortisol, testosterone, LH and FSH decreased. LH, FSH and testosterone did not sufficiently respond to GnRH or hCG stimulation. Gene analysis indicated that C368F mutation was located in exon 1 of DAX-1 gene.

Objective To investigate the expression and effect of high mobility group box 1(HMGB1) and its signaling pathway(HMGB1 RAGE/TLR4-NF-κB-cytokines)in rats with dilatd cardiomyopathy(DCM).Methods The rats were divided into two groups:normal control group (control,n=20) which treated with physiological saline,and DCM group(n=22) which treated with adriamycin(1 mg/kg twice a week)for 6 weeks,and then observed for 2 weeks.Echocardiography was performed at the end of the study.Plasma IL-1,IL-6,TNF-α level were measured by the flow cytometry.The CRP,BNP concentrations were measured by enzyme linked immunosorbent assay (ELISA).The expression of HMGB1 mRNA,TLR4 mRNA,RAGE mRNA,NF κB mRNA were measured by real time PCR.Results There were four rats dead in the DCM group;two rats were randomly selected from the DCM group to certified modeled successfully by echocardiography and pathological examination.Left ventricular end-diastolic diameter (LVEDD) and left ventricular end systolic diameter (LVESD) in DCM group were significantly higher than those in the normal control group(P＜0.05);left ventricular ejection fraction (LVEF),left ventricular short axis contractility(FS) in DCM group was significantly lower than that in normal control group(P＜0.05).The expression of H MGB1 mRNA,TLR4 mRNA,RAGE mRNA and NF-κB mRNA in myocardial tissue were significantly increased in DCM group than in the normal control saline group (P＜ 0.05),The expression of HMGB1 mRNA were positively correlated with TLR4 mRNA,RAGE mRNA and NF κB mRNA(r=0.873,P=0.005;r=0.949;P=0.000;r=0.898,P=0.002).The serum levels of IL-1,IL 6,TNF α and CRP were significantly higher in DCM group.The expression of HMGB1 mRNA in myocardial tissue was positively correlated with IL 1,IL-6,TNF-α and CRP(r=0.944,P=0.002;r=0.988,P=0.000;r=0.968,P=0.000;r=0.961,P=0.000).Conclusion HMGB1 and it's inflammation signaling pathway (HMGB1-TLR4/RAGE-NF-κB-cytokines) were highly expressed in dilated cardiomyopathy,and have relationship with left ventricular diameter and cardiac function,they may be involved in the development of DCM.

Objective: To explore the application of18F-lfuorodeoxyglucose (FDG) micro- positron emission tomography (PET) myocardial metabolism imaging for evaluating dilated cardiomyopathy model (DCM) in experimental rats. Methods: A total of 12 male SD rats were randomly divided into 2 groups: DCM group, the rats received intraperitoneal injection of adriamycin at 1.0 mg/kg twice per week and Control group, the rats received intraperitoneal injection of normal saline, all animals were treated for 6 weeks followed by 2 weeks observation.n=6 in each group. Echocardiography was performed at pre- and post-modeling,18F-FDG micro-PET myocardial metabolism imaging was conducted after modeling and plasma level of BNP was examined as well. Finally, the rats were scariifed to observe the pathological changes of myocardial tissue. Results: 1 rat died in DCM group and the rest were with successful modeling conifrmed by echocardiography and pathology. Compared with Control group, DCM group showed decreased standard uptake value of18F-FDG (1.23 ± 0.55) vs (6.65 ± 0.41),P<0.01; the standard uptake value of18F-FDG was negatively related to left ventricular end diastolic diameter (LVEDD) (R=-0.709,P=0.015), LVESD (R=-0.924, P=0.000) and plasma level of BNP (R=-0.948,P=0.000), while positively related to LVEF (R=0.968,P=0.000) and fractional shortening (R=0.863,P=0.001). Conclusion:18F-FDG micro-PET myocardial metabolism imaging combining echocardiography, biochemical and pathological examinations may evaluate DCM modeling in rats, which provide a non-invasive and intravital tool for small animal experiment.

Objective To investigate the role of AcrAB-TolC efflux pump in fluoroquinolones resistance by Shigella. spp and to explore the significance of AcrAB-TolC efflux pump on mutation of acrR, soxS and marOR as well as on drug re?sistence. Methods Drug resistant bacteria were selected by Kirby-Bauer disk diffusion test. After addition of efflux pump inhibitor carbonylcyanide-m-chlorophenylhydrazone (CCCP), change of minimal inhibitory concentration (MIC)s of nilidixic acid, Levofloxacin, ofloxacin, ciprofloxacin and Norfloxacin were examined. The DNA binding region of acrA, acrB, soxS, acrR and marOR gene in these mutants were amplified by PCR and sequenced. Results Among the 159 clinical isolates of Shigella,11 strains are resistant to fluoroquinolone. After the addition of CCCP, MICs of 2 fluoroquinolone resistant strains decreased; the MICs of 7 fluoroquinolone resistant strains did not change; MICs of 2 fluoroquinolone resistant strains in?creased. The corresponding nucleotides C, A, T, T on the 36th to 39th of marOR gene were missing, showing by sequencing, in fluoroquinolone resistent strains which might be regulated by the efflux pump gene AcrAB-TolC. Conclusion Efflux pump inhibitor could restrain the activity of efflux partially. The mutations of marOR might play an important role in fluoroquino?lone resistent by shigella.
