Objective:To enhance the comprehensive learning and clinical practice capabilities of intravenous therapy specialized nurses based on the "Internet+" and standardized patient (SP) multidisciplinary linkage teaching.Methods:In this study, 54 nurses who took training of the intravenous therapy specialists in Chaoyang Hospital affiliated to Capital Medical University from July 2019 to December 2019 were selected as research subjects and randomly divided into a control group and a study group, with 27 ones in each group. The control group used traditional training of intravenous therapy specialized nurse, and the research group used the multidisciplinary linkage model of "Internet+" and SP. After the training, the nurses were assessed for theoretical and practical operation and satisfaction surveys, and the incidence of venous catheterization complications during the training of the two groups of nurses was counted. SPSS 22.0 was used for t test and chi-square test. Results:There was no statistically significant difference between the two groups of nurses in the theoretical assessment of basic knowledge and professional knowledge ( P>0.05). The total score of case analysis and theoretical assessment of the study group was higher than that of the control group, and the difference was statistically significant ( P<0.001). The nurses of the study group scored higher than the control group did in such 8 aspects, namely, central venous catheter (CVC) maintenance, peripherally inserted central catheter (PICC) placement, PICC maintenance, infusion port maintenance, peripheral venous catheters, aseptic technique, prevention and treatment of catheterization complications, and health education, with statistically significant differences ( P<0.05). There were statistically significant differences in the average score of nurse satisfaction between the two groups [(85.4±3.7) vs. (95.7±2.6)], and in the incidence of complications between the two groups ( χ2=4.618, P=0.032). Conclusion:"Internet+" and SP multidisciplinary linkage teaching helps to enhance the comprehensive learning and clinical practice ability of intravenous therapy specialized nurses, reduce the incidence of complications, enable patients to receive high-quality intravenous infusion therapy and care, and ensure the safety of patients.

Objective To explore the effect of inhibition of miR-214 expression on the proliferation of hepatocellular carcinoma cells via regulation of E2F3 expression.Methods The expression of miR-214 in SMMC-7721, HepG2, SK-Hep-1 and Huh 7 cells was examined by RT-PCR.Hepatocellular carcinoma cells were transfected with miR-214 NC and miR-214 mimics with liposomes.The expression of miR-214 was detected by RT-PCR.The cell viability was detected by MTT assay.Cell apoptosis was detected by Hoechst staining.Cell cycle was detected by flow cytometry.Western blot, RT-PCR and dual luciferase reporter gene assay were used to detect whether E2F3 was a downstream target gene of miR-214.Results The expression of miR-214 in SMMC-7721, HepG2, SK-Hep-1 and Huh 7 cells was 0.83±0.08, 0.32±0.03, 0.33±0.03, and 0.08±0.01, respectively.The expression of miR-214 in the HepG2 cells was the lowest, so HepG2 cells were selected as the subsequent experimental cell line.Compared with the miR-214 NC group, the expression of miR-214 (0.65±0.06 vs.0.14±0.01) was up-regulated, the cell viability (0.35±0.03 vs.0.69±0.06) was decreased, cell apoptosis rate [(36.37±3.43)% vs.(3.74±0.34)%] was increased, the G1 phase of the cell cycle (57.79±5.78 vs.45.319±4.53) was prolonged, the expression of E2F3 protein (0.23±0.02 vs.0.98±0.09) and mRNA (0.24±0.02 vs.0.99±0.10) was significantly down-regulated in the miR-214 mimics group (P<0.01).Conclusion miR-214 mimics suppress the HepG2 cell proliferation via targeted down-regulation of E2F3 expression.

Objective To establish a high performance liquid chromatography (HPLC) method for determining phenytoin concentration in epilepsy patients' plasma,and compare this method with chemiluminescence microparticle immunoassay (CMIA),and to evaluate the consistency of the two methods.Methods HPLC and CMIA methods were applied to determine the plasma concentration of phenytoin in 60 epileptic patients,respectively.The difference of results was analyzed by two-side paired t-test,and then the correlation and consistency of the two methods were investigated with Passing-Bablok regression and Bland-Altman method.Results There was no significant difference between the results of the two methods (P >0.05).The regression equation of the determination results by HPLC (Y) and CMIA (X) was Y=0.992 9X +0.143 7 (R2 =0.992 6,n =60),which indicated the correlation of the two methods was good.Bland-Altman analysis showed that the consistency of the two methods for determining was good.Conclusion HPLC and CMIA method in monitoring plasma concentration of phenytoin have good correlation and consistency.Both methods can be used for therapeutic drug monitoring of phenytoin.

Objective To compare the efficacy and safety of standard or reduced doses of bortezomib combined with adriamycin and dexamethasone in patients with multiple myeloma (MM).Methods Fifty-two newly diagnosed,refractory and relapsed patients received bortezomib [1.3 mg/m2 (standard dose group,26 patients) or 1.0-1.1 mg/m2 (reduced dose group,26 patients) on day 1st,4th,8th and 11 th],and adriamycin (10 mg/m2) plus dexamethasone (40 mg/d) on day 1 st-4th,and were treated for 1-6 courses.Adverse events were graded and compared.Results After treatment,the overall response rate of standard dose group [80.8%(21/26)] and reduced dose group [88.5%(23/26)] had no significant difference (P =0.739).The rate of neutropenia and thrombocytopenia in two groups had no significant difference[23.1%(6/26) vs.15.4%(4/26),P=0.281 ; 11.5%(3/26) vs.7.7%(2/26),P=0.620].The rate of Ⅲ-Ⅳ grade peripheral nerve disease,herpes zoster,lack of power and abdominal distension in standard dose group were significantly higher than those in reduced dose group [15.4%(4/26) vs.3.8%(1/26),P =0.038;26.9%(7/26) vs.7.7%(2/26),P =0.029;38.5%(10/26) vs.15.4%(4/26),P=0.045; 19.2%(5/26)vs.3.8% (1/26),P =0.028].Conclusion Reduced dose of bortezomib appears to result in similar overall response rate,but better tolerance and safety compared with standard dose.
