Study on the Molecular Mechanism of Stephania Terandra in the Therapy for Hypertension Based on Inte-grated Pharmacology Platform / 中国药师

Objective: To explore the potential genetic target of Stephania terandra in the therapy for hypertension based on inte-grated pharmacology platform to study the molecular mechanism of Chinese medicines in treating hypertension. Methods: Using the functional prediction modules of integrated pharmacology platform and the functional modules of network construction, the component-target network of Stephania terandra was calculated, and the target network of anti-hypertension was further calculated, and the target molecules related to hypertension were explored. Results: A total of 198 targets related to hypertension were obtained from the hyper-tension prevention. Among them, there were 59 potential action nodes and 20 known action nodes. The nodes with direct action were type-2 angiotensin Ⅱ receptor ( AGTR2), type-1 angiotensin Ⅱ receptor ( AGTR1), prostacyclin receptor ( PTGIR), solute carrier family 12 member 3 (SLC12A3) and endothelin-1 (EDN1). The GO enrichment and KEGG pathway enrichment of Stephania terandra chemical components showed a close correlation with hypertension, and the molecular mechanism of the target was clear. Conclusion:Through the integration of pharmacology platform, the targets of Stephania terandra-disease are deeply explored, and its potential mo-lecular mechanism as well as potential factors is studied.

Medication Analysis of Electrolyte Disturbance with Suspected Deteriorated Demyelination Post PCI / 医药导报

Objective A case would be discussed on suspected demyelination due to electrolyte disturbance to provide references for clinical pharmacists to carry out pharmaceutical care. Methods A pharmaceutical care case on PCI postoperative acute heart failure and contrast induced nephropathy with suspected demyelization due to electrolyte disturbance was introduced through a combination of analysis on clinical symptoms,renal function,electrolyte,blood glucose level and further discussion on consciousness change reason, diuretic use, electrolyte management, and other related issues. Results Clinical pharmacist should provide more care to patients with abnormal blood sodium and osmotic pressure,pay more attention to the calculation and evaluation of rehydration sodium/filling quantity and speed, accumulate more knowledge of contrast induced nephropathy, and raise their awareness on the identification of high risk population. Conclusion Arrhythmia,heart failure,renal failure,infection can beincentives to one another,and thus doctors and pharmacists must pay more attention to the comprehensive situations.

Analysis of Effects of Antimicrobial Drug Application Management in Our Hospital during 2011 to 2013 / 中国药房

OBJECTIVE:To consolidate the results of special antibacterial drug rectification so as to improve the rational medi-cation of antibacterial drugs. METHODS:By using the method of retrospective analysis,the antibacterial drug application data in 2011(before rectification and initial stage of rectification),2012(middle stage thereof)and 2013(later stage thereof)were sum-marized,compared and analyzed. RESULTS:After special rectification(Jan. 2011 vs. Dec. 2013),the utilization rate of antibacte-rial drugs in perioperative period for class I incision decreased from 80.42% to 24.49%. That of antibacterial drugs in emergency treatment decreased from 53.79% to 36.23%. The examination rate of microbial samples in inpatients who would use special-grade antibacterial drugs increased from 16.12% to 94.17%. The use intensity of antibacterial drugs by inpatients decreased from 70.28 DDDs/(100 persons·d) to 27.44 DDDs/(100 persons·d). The utilization rate of antibacterial drugs by inpatients decreased from 65.99% to 46.45%. CONCLUSIONS:Special rectification has remarkable effects on rational clinical application of antibacterial drugs. Regulation and evaluation should be strengthened to maintain the effects and continuously improvement should be made.

Radial head replacement versus open reduction and internal fixation for comminuted radial head fractures:more advantageous? / 中国组织工程研究

BACKGROUND:At present, the methods of treating unstable comminuted radial head fractures contain open reduction and internal fixation and metal prosthesis replacement. There were success cases treated by the two methods, but some shortcomings simultaneously existed. OBJECTIVE:To compare the clinical therapeutic effects of replacement of the radial head with metal prosthesis with open reduction and internal fixation for the treatment of unstable comminuted radial head fractures. METHODS:A prospective randomized control ed analysis was performed in 45 cases of unstable comminuted radial head fractures. These cases received open reduction and internal fixation and metal prosthesis replacement. This study compared the Broberg and Morrey elbow joint function score and the incidence of complications after fixation, and performed statistical analysis. RESULTS AND CONCLUSION:The subjects were fol owed up for 1-5 years, averagely 2.8 years. According to Broberg and Morrey scores, the average score was 90.1 and the incidence of complications was 13.6%in the prosthesis replacement group. The average score was 76.8 and the incidence of complications was 47.9%in the open reduction. Significant differences were visible between the two groups (P<0.01). Compared with the open reduction group, prosthesis replacement for unstable comminuted radial head fractures obtained better joint function and lower incidence of complications.

Anti-inflammatory mechanism of qingfei xiaoyan wan studied with network pharmacology / 药学学报

This study aims to clarify out the anti-inflammatory mechanism of Qingfei Xiaoyan Wan. Chemical constituents of Qingfei Xiaoyan Wan identified by UPLC Q-TOF, were submit to Molinspiration, PharmMapper and KEGG bioinformatics softwares for predicting their absorption parameters, target proteins and related pathways respectively; and the gene chip and real time-PCR were carried out to investigate the expression of inflammatory genes on lung tissue of guinea pigs or human bronchial epithelial cell lines. The predicted results showed that 19 of the 24 absorbable constituents affected at 9 inflammation-related pathways through 11 protein targets; Qingfei Xiaoyan Wan treatment can significantly reduce the infiltration of cytokines through ERK1 gene and 5 inflammatory pathways (Focal adhesion, Fc epsilon RI, Toll-like receptors, NK cell-mediated cytotoxic, and ERK/MAPK). The results of real time-PCR further confirmed that the anti-inflammatory effects of Qingfei Xiaoyan Wan were due to active ingredients such as arctigenin, cholic acid and sinapic acid intervened focal adhesion, Fc epsilon RI signaling and ERK/MAPK pathways. The novel approach of 'drug-target-pathway' will present an effective strategy for the study of traditional Chinese medicines.
