OBJECTIVE:To discuss the application of rational drug use software system in drug dispensing in outpatient depart-ment of our hospital. METHODS:The application of rational drug use software system (included clinical decision support soft-ware,drug dispensing software and drug management software) in prescribing (warning in advance),dispensing (intervention in the event)and the prescription review(the post review)in outpatient department of our hospital were all introduced. Outpatient pre-scription checking and intervention were collected from our hospital after the application of rational drug use software system to evaluate the effect of the software system. RESULTS & CONCLUSIONS:Rational drug use software system is adopted to realize scientific,convenient and express monitoring and management of prescription drug use in advance,in the course and afterwards. A total of 721 507 outpatient prescriptions were checked in our hospital from Jan. to May in 2015;0.17‰prescriptions were intercept-ed by system warning;system pointed out and pharmacists had checked 23.25% prescriptions;the rate of qualified prescription was more than 99.96%. After pharmacists intervention,various types of irrational prescriptions decreased significantly (P<0.01). It is suggested that pharmacists should make full use of information system,at the same time,optimize and improve the system through active exploration so as to improve rational drug use.

Objective:To analyze the statuses of CD8 + T cell exhaustion in patients with human immunodeficiency virus (HIV) infection, Mycobacterium tuberculosis (MTB) infection and co-infection. Methods:A total of 87 patients infected with HIV and/or MTB in Wuxi Fifth People′s Hospital and Taicang First People′s Hospital from August 2019 to January 2020 were enrolled, including 18 cases of HIV infection, 34 cases of active tuberculosis (ATB), 19 cases of latent tuberculosis infection (LTB), seven cases of HIV coinfected with ATB, and nine cases of HIV coinfected with LTB. Another 11 healthy controls were also included. The peripheral blood of all subjects was collected for cell surface staining and intracellular cytokine staining, and flow cytometry was used to detect the expressions of activation molecules including CD62 ligand, CD44 and CD127, the transcription factor like eomesodermin (EOMES), T cell factor 1 (TCF-1), T-box expressed in T cells (T-bet), B lymphocyte-induced maturation protein 1 (Blimp-1), inhibitory receptors including programmed death-1 (PD-1) and T-cell immunoglobulin and mucin domain 3 (Tim-3) on CD8 + T cells. Mann-Whitney U test was used for statistical analysis. Results:The mean fluorescence intensities (MFIs) of the activation molecules CD62 ligand and CD44 in the HIV group were lower than those in the healthy control group, while the inhibitory receptor Tim-3 was higher than that in the healthy control group. The differences were all statistically significant ( U=31.00, 1.00 and 0.00, respectively, all P<0.010). The MFIs of CD62 ligand and CD44 in HIV coinfected with LTB group were lower than those in LTB group, while PD-1 and Tim-3 were higher than those in LTB group. The differences were all statistically significant ( U=4.00, 26.00, 6.00 and 3.00, respectively, all P<0.010). The MFIs of CD62 ligand, CD44 and CD127 in HIV coinfected with ATB group were lower than those in ATB group, while PD-1 and Tim-3 were higher than those in ATB group. The differences were all statistically significant ( U=9.00, 40.00, 45.50, 28.00 and 7.00, respectively, all P<0.010). The proportion of terminal effector CD8 + T cells in the HIV group was higher than that in the healthy control group, while the proportion of central memory CD8 + T cells was lower than that in the healthy control group. The differences were both statistically significant ( U=15.00 and 33.00, respectively, both P<0.010). The proportion of terminal effector CD8 + T cells in the HIV coinfected with LTB group was higher than the LTB group, while the proportion of central memory CD8 + T cells was lower than that in the LTB group. The differences were both statistically significant ( U=7.00 and 20.00, respectively, both P<0.010). The proportion of terminal effector CD8 + T cells in the HIV coinfected with ATB group was higher than that in ATB group, while the proportion of central memory CD8 + T cells was lower than that in ATB group. The differences were statistically significant (both U=7.00, P<0.001). The expression level of PD-1 + Tim-3 + T cells in HIV group was higher than that in healthy control group, that in HIV coinfected with LTB group was higher than that in LTB group, and that in HIV coinfected with ATB group was higher than that in ATB group. The differences were all statistically significant ( U=21.00, 6.00 and 5.50, respectively, all P<0.001). The MFI of transcription factors EOMES and TCF-1 in HIV coinfected with LTB group were lower than those in HIV group, while the MFI of T-bet was higher than that in HIV group. The differences were all statistically significant ( U=3.00, 4.00 and 9.00, respectively, all P<0.001). The MFI of EOMES and TCF-1 in HIV coinfected with ATB group were lower than those in HIV group, while the MFI of T-bet and Blimp-1 were higher than those in the HIV group. The differences were all statistically significant ( U=11.00, 14.00, 7.00 and 22.00, respectively, all P<0.050). Conclusions:MTB co-infected with HIV patients present lower immune function and a higher degree of CD8 + T cell exhaustion. In addition, HIV patients co-infected with LTB and ATB have a higher degree of CD8 + T cell exhaustion than HIV infected patients.
