ABSTRACT

Objective:To analyze drug-related problems (DRPs) of hospitalized elderly patients with limited life expectancy.Methods:A total of 261 patients aged ≥ 70 years with limited life expectancy according to the 1-year mortality prediction index, who were admitted in the geriatric ward of Peking Union Medical College Hospital from January 2015 to December 2021 were included. According to Strand system, the categories, medications and interventions of DRPs were analyzed.Results:Among 261 patients, 187 (71.6%) had 672 DRPs. The most common DRPs were related to drug safety, including 271 (40.3%) adverse drug reactions and 149 over dosages (22.2%). A total of 207 drugs were involved in DRPs, and the top 5 classes with higher frequency of DRPs were antiinfectives for systemic use(20.7%,139/672), nervous system drugs(19.4%,130/672), alimentary tract and metabolism drugs(16.5%,111/672), cardiovascular system drugs(16.1%,108/672), and blood and hemopoietic organs drugs(13.7%,92/672). The recommendations were given by pharmacists for all 672 DRPs, and 643 were accepted by physicians (95.7%). The therapy need to be adjusted in 564 recommendations and the medications need to be monitored in 108 recommendations. In recommendations of therapy adjustment, 49.6%(280/564) were related to deprescribing. The deprescribing with higher frequency included antiinfectives for systemic use(29.6%, 83/280), lipid modifying agents(7.9%,22/280) and antithrombotic agents(7.9%,22/280). Patients with severe disability had significantly higher average DRPs(2 vs. 1) and average deprescribing(1 vs. 0) than patients without severe disability( Z=-4.83, Z=-3.61, all P<0.001). Conclusion:Drug safety is the most common DRP in limited life expectancy elderly inpatients, particularly for those with severe disability.

ABSTRACT

In order to identify the chemical constituents of Yushu tablets comprehensively, we studied the chemical constituents of CHCl3 extract from Yushu tablets by the ultra performance liquid chromatography-electrospray ionization-ion trap-time of flight mass spectrometry (UPLC-ESI-IT-TOF/MS). It showed that there were more than 100 compounds separated, and forty-nine peaks among these were identified on the basis of high resolution mass spectrometry data and literature data reported. Determination of twelve peaks was further confirmed by standard substances. These components assigned to the different plant sources mainly included phenylpropanoids, triterpenoids, quinones and m-trihydroxybenzene compounds. By analyzing the chemical components of CHCl3 extract from compound Chinese medicine Yushu tablets comprehensively, this study provided the foundation for studying chemical components, pharmacodynamic substance and quality control of Yushu tablets.

ABSTRACT

Objective To investigate the possible mechanism of natural killer cells(NK cells)in immune dysfunction in sepsis by monitoring the phenotype and function of periphery NK cells in patients with sepsis. Methods A retrospective study was conducted. The patients with systemic inflammatory response syndrome(SIRS,n=59)or sepsis(n=65)admitted to Department of Critical Care Medicine of Anhui Provincial Hospital from August 2011 to August 2013 were enrolled. Blood samples were collected within 48 hours after intensive care unit(ICU)admission,the phenotype and function of periphery NK cells were determined by flow cytometry. Twenty-eight healthy people served as controls. Results The proportion and number of peripheral blood CD3-CD56+NK cells in SIRS and sepsis groups were normal,and no statistical difference was found when compared with those of the healthy control group〔cell proportion:0.102±0.019,0.102±0.108 vs. 0.106±0.018,F=0.018,P=0.982;cell number(×106/L):182.46±65.98, 172.97±63.51 vs. 179.25±60.44,F=0.349,P=0.706〕. It was shown by NK cell degranulation detection that there was no significant difference in the expression of CD107 and interferon-γ(IFN-γ)secretion〔CD107:0.135±0.050,0.140±0.058,0.128±0.070,F=0.583,P=0.560;IFN-γ(kU/L):14.36±4.74,12.49±4.21, 13.45±5.04,F=1.616,P=0.202〕among healthy control group,SIRS group,and sepsis group. It was shown by antibody dependent cytotoxic effect(ADCC)test that there was no difference in the expression of CD107 among healthy control group,SIRS group,and sepsis group(0.574±0.166,0.643±0.165,0.581±0.157,F=0.808,P=0.448). When compared with healthy controls,the secretion of IFN-γwas increased in SIRS patients(kU/L:40.5±13.2 vs. 28.4±9.6,P=0.001),while reduced in sepsis patients(kU/L:19.8±6.7 vs. 28.4±9.6,P<0.01). Compared with SIRS group,only NK cell surface inhibitory receptors CD158e(KIR 3DL1)expression in sepsis group was significantly increased(0.203±0.057 vs. 0.079±0.021,t=15.762,P<0.001),and there were no significant differences in the other phenotype between the two groups. Compared with SIRS group,the IFN-γproduction of the sepsis group was significantly lowered(kU/L:0.280±0.040 vs. 0.310±0.038,t=3.390,P=0.009),and the level of IL-12 was also significantly decreased(ng/L:0.15±0.03 vs. 0.30±0.08,t=32.832,P<0.001). Conclusion It was showed by NK cell phenotype and function assay that the function of NK cells in patients with sepsis was impaired and led to a poor production of IFN-γ. The IFN-γmediated immune dysfunction may be a main reason for the disorder of NK cell function,which laid the foundation of the clinical immune intervention practice to improve to NK cell function.
