ABSTRACT
Due to the COVID-19 pandemic, the teaching of Biopharmaceutical Engineering course was carried out online and completed with satisfactory outcomes. In order to improve the efficiency of online teaching, ensure the substantive equivalence between online and offline teaching and achieve effective teaching, this article summarized the exploration and practical experience of online teaching, taking the Biopharmaceutical Engineering course as an example. This includes analysis of learner characteristics, selection of online teaching platform, development of teaching resources, optimization of teaching contents, BOPPPS teaching method-based design of teaching structure, and reflection of effective teaching. This paper is expected to provide a useful reference for online teaching.

OBJECTIVE:To compare the efficacy and safety of dabigatran and warfarin respectively used in atrial fibrillation patients after radiofrequency ablation(RFCA). METHODS:Data of 141 nonvalvular atrial fibrillation patients,who scheduled for RFCA,were retrospectively analyzed and divided into warfarin group(71 cases)and dabigatran group(70 cases)by different med-ication. Patients in warfarin group should stop warfarin if they took before,then changed to Low molecular weight heparin calcium injection 100 U/kg,subcutaneous injection,taking RFCA when INR was lower than 1.5,stopping low molecular weight heparin 12 h before surgery;Low molecular weight heparin calcium injection 100 U/kg was intravenously injected when surgery;orally tak-ing Warfarin sodium tablet 4.5 mg after 4-6 h,once a day,meanwhile bridged overlapping treated at least 3-5 d with low molecu-lar weight heparin;monitoring once INR every 3 d after surgery,maintaining INR 2.0-3.0,taking warfalin at least 3 months. Pa-tients in dabigatran group stopped taking the anticoagulant drugs when admission,then changed to Dabigatran etexilate capsule 110 mg(age≥70 years old or body mass0.05). CONCLUSIONS:Dabigatran has similar anticoagulant efficacy and safety with warfarin in atrial fibrillation pa-tients after RFCA.
ABSTRACT
Objective:To evaluate the effectiveness and safety of anticoagulant therapy with rivaroxaban in atrial fibrillation( AF) pa-tients after radiofrequency catheter ablation( RFCA) . Methods:A retrospective analysis was performed in the study. Totally 141 AF pa-tients with RFCA in our hospital were enrolled from January 2014 to October 2015. The patients were divided into rivaroxaban group(70 patients)and warfarin group (71 patients). In rivaroxaban group,rivaroxaban(10 mg, po,qd)was given for at least 3 months after RFCA. In warfarin group,low molecular heparin (100 IU·kg-1,ih) was given before RFCA, and standard dose of warfarin (3-5 mg,po,qd) was given for at least 3 months by adjusting the INR within the range of 2. 0-3. 0 after RFCA as bridging therapy. The death rate, throm-boem bolism events and bleeding events between the groups were evaluated and companed groups. Results: There were no significant differences in baseline characteristics between the groups except the diastolic pressure. There were no significant differences in the death and thromboembolism events(transient cerebral ischemia , ischemic encephalopathy, 2/70 vs 4/71,P>0. 05)between the groups. There were no TIMI major bleeding events in both groups. There were no significant differences in minor bleeding events between the groups (3/70 vs 4/71,P>0. 05). Conclusion: Compared with those of warfarin,the effectiveness and safety of rivaroxaban show the similar effect in AF patients after RFCA. Rivaroxaban can be safely and effectively used in AF patients with low or middle risk of thromboembo-lism after RFCA.
ABSTRACT
Objective: To discuss the pharmaceutical care experience of clinical pharmacists in the antibacterial agents application in one patient with infection after coronary artery bypass graft ( CABG) . Methods:The clinical pharmacist participated in the treatment of the patient after CABG. According to the relevant laboratory indices and the extent of the infection combined with the vital signs of the patient, the pharmacist formulated and adjusted the anti-infection therapeutic regimen. The therapeutic effects and adverse reactions were observed as well. Results: Safte and high-quality individualized pharmaceutical service was provided to the patient by the pharmaceutical care of the clinical pharmacist in anti-infection treatment. Conclusion:Through the above practice, clinical pharmacists have played a positive role in reasonable using of anti-infective drugs in patients with cardiac surgery.
ABSTRACT
Objective To construct reference standards for detection and quantification of Klebsiella pneumoniae (K.pneumoniae) with SYBR Green I-based real-time PCR assay. Methods Primers were designed based on the published sequence of the phoE gene of K.pneumoniae. The standard was prepared by cell culture, PCR and T-A clone methods, and was identified by colony PCR and DNA sequencing. Results The standard curve showed a very good linear negative regression between threshold cycle (Ct) and Log starting quantity of copy number. The detection range was from 5.2 to 5.2×106 copies per reaction, and the detection limit was 6 copies per reaction. The coefficients of variance (CVs) of three parallel experiments were in the range of 0.05%-0.91%. Conclusion The reference standards have high stability and reproducibility. They can be used in the quantitative detection of K.pneumoniae.
