Objective To explore the role of clinical pharmacists in rational drug use through the pharmacy care of an elderly pneumonia patient with Chlamydia psittaci infection and drug-induced liver injury. Methods The clinical pharmacists participated in the treatment of one patient with Chlamydia psittaci pneumonia and drug-induced liver injury. Based on the results of second-generation gene sequencing, the characteristics of the pathogen were learned by literature search. The clinical pharmacists monitored the patient’s liver and kidney function, provided a new medication treatment plan to Doctors, and performed patient education during the treatment. Results The initial empirical anti-infective treatment with teicoplanin and imipenem-cilastatin was not effective. After the diagnosis of Chlamydia psittaci and Candida albicans infection, the combination of doxycycline with azithromycin and fluconazole was administered. Drug-induced liver injury was found with this treatment. The clinical pharmacist proposed to switch to doxycycline and clarithromycin with co-administration of magnesium isoglycyrrhizinate and polyene phosphatidylcholine to protect the liver. With this new regime, patient's liver function was improved and the infection was under control. Conclusion Individualized pharmaceutical cares provided by clinical pharmacists helped the safe, rational and effective use of medications.

Objective To study the irrational intravenous (IV) medication orders and promote rational medication applications.Methods A retrospective analysis was conducted to analyze the irrational prescriptions from January to December 2016.Results Among 39 948 IV medication orders reviewed, there were 134 irrational prescriptions of cytotoxic drugs (0.33％) and 222 irrational prescriptions of total parenteral nutrition(TPN)(0.56％).Within 356 irrational prescriptions, 19 had improper amount of diluent(5.34％), 95 inappropriate dosage(26.69％), 12 drug incompatibility(3.37％), 8 wrong diluent (2.24％) and 222 inappropriate TPN orders (62.36％).Conclusion The interventions of the clinical pharmacists are needed to reduce medication errors and improve the drug safety and effectiveness.

Objective To explore the effect and significance of electronic account books on the management of anesthesia and psychotropic drugs. Methods The data of electronic account books from January 2020 to June 2020 in the inpatient pharmacy of the hospital (observation group), and manual account books from July 2019 to December 2019 (control group) were collected respectively. The data of daily accounting time, monthly settlement accounting time and accounting accuracy between the two groups were compared and analyzed. Results The daily average time for pharmacists to manually accounting was (162.8±22.5) min, and the daily average time for pharmacists to make accounts electronically was (33.2±7.0) min. It took (245.5±7.2) min for manual accounting of monthly settlement and (46.8±2.5) min for electronic accounting of monthly settlement. The accuracy rate of daily counting records, special account books, special register and empty ampoule waste paste recovery records included in electronic accounting is up to 100%. Conclusion The implementation of electronic account books not only significantly improved the work efficiency of pharmacists, but also strengthened drug supervision, formed a comprehensive traceability system, which could ensure the safety of clinical medication, and make the management of narcotic psychotropic drugs more efficient and standardized.

Objective To explore the anti-inflammatory and hepatoprotective mechanism of Shuganning injection through establishing the active ingredients-targets network and protein interactions network. Methods The main active ingredients of Artemisiae scopariae, Fructus gardenia, Radix scutellariae, Radix isatidis and Ganoderma in Shuganning injection were obtained by TCMSP; GeneCards and OMIM were used to screen the hepatitis-related targets among the corresponding targets of the active ingredient of Shuganning injection; The Cytoscape software was used to construct the active ingredient-targets network of Shuganning injection. The protein interactions network was constructed using the String database and Cytoscape software. The GO and KEGG pathways involved in the targets were analyzed by DAVID database. Results The results showed that 20 active ingredients and 83 targets of Shuganning injection were involved. GO analysis showed that Shuganning injection mainly affected the regulation of cellular processes and biological processes, as well as the response to chemical stimulation and stress. KEGG pathway analysis showed that the targets of the anti-inflammatory and hepatoprotective effect of Shuganning injection mainly involved in signaling pathways such as TNF, IL-17, and MAPK. Conclusion The anti-inflammatory and hepatoprotective effect of Shuganning injection have the characteristics of multiple components, multiple targets and multiple pathways, which may play a role by regulating pathways such as TNF、IL-17 and MAPK .

Objective : To investigate the effect of different decontamination methods, including photodynamic therapy, sandblasting and titanium curette, on titanium surface morphology and bacterial adhesion for the treatment of peri-implant disease. Methods: Porphyromonas gingivalis (Pg) and Fusobacterium nucleatum (Fn) were inoculated on the surface of polished titanium specimens, and titanium specimen surfaces were treated with different decontamination methods after incubation. The titanium specimens were divided into a no-treatment control group, photodynamic group, sandblasting group and titanium curette group according to different decontamination methods. The changes in titanium surface roughness were observed by atomic force microscopy (AFM), and the remaining bacteria on the titanium surface were observed by scanning electron microscopy (SEM) and live/dead bacteria staining tests. After reinoculation of Pg and Fn, bacterial readhesion was observed on the surface of decontaminated titanium specimens. Results : The AFM results showed that the surface roughness of the titanium curette group was significantly higher than that of the no-treatment control group, photodynamic group and sandblasting group (P<0.05), and there was no statistically significant difference between the no-treatment control group, photodynamic group and sandblasting group (P>0.05). The results of contact angle measurement showed that the surface contact angle of each treatment group was smaller than that of the no-treatment control group (P<0.05). The SEM results obtained after the titanium specimen surface was decontaminated showed that the number of bacteria on the no-treatment control group surface was higher and the bacteria were relatively concentrated. The bacteria on the surface of the photodynamic group, sandblasting group and titanium curette group were scattered and distributed in small numbers, and most bacteria on the surface of the photodynamic group were ruptured. The results of the live/dead bacteria staining experiment showed that the percentage of dead bacteria on the surface of the photodynamic group was significantly higher than that of the no-treatment control group, sandblasting group and titanium curette group (P<0.05). The remaining bacteria on the surface of the sandblasting group and titanium curette groups were mainly live bacteria. The remaining bacterial adhesion on the surface was significantly reduced for the sandblasting group compared to the no-treatment control group and the photodynamic and titanium curette groups (P<0.05). SEM and live/dead bacteria staining results of bacterial readhesion on the surface of titanium specimens showed that there was an aggregation of Pg on the surface of the titanium curette group, and its surface bacterial adhesion was significantly higher than that of the no-treatment control group, photodynamic group and sandblasting group. Conclusion In mechanical decontamination, sandblasting machines are a better option than photodynamic therapy and titanium curettes; however, sandblasting does not remove all bacterial contamination. For sterilization, photodynamic therapy is more effective than sandblasting and titanium curettes. A combination of sandblasting and photodynamic therapy methods for the treatment of peri-implant disease may be considered in clinical practice.
