Objective To explore the effects of Compound Antler capsule on the NO secretion of macrophages, cell cycle and[Ca2 +]i of mouse T lymphocytes.Methods ICR mice were randomly divided into 4 groups:experimental groups were respectively given Compound Antler capsule 233, 467, 1400 mg/kg via intragastric administration once a day and the control group were given the same volume of water for 30 days.NO concentration of mouse peritoneal macrophages was measured by Griess assay.The cell cycle distribution of activated mouse spleen lymphocytes was measured by flow cytometry.Fluorescent probe Fluo 4-AM was used to mark Ca2 + in lymphocytes, and the changes of its fluorescence intensity were observed with the multiscan spectrum.Results The result showed that NO concentration in experimental groups was higher than that in control group (P<0.01).More activated spleen lymphocytes of 467, 1400 mg/kg dose groups were entried into S and G2/M phase than control group (P<0.05).After activated by ConA for 8 min, the intracellular[Ca2 +]i in mouse spleen lymphocytes of 233, 1400 mg/kg dose group was higher than that of control group, respectively (P<0.05).After activated by LPS for 1, 4, 8 min, the[Ca2 +]iin mouse spleen lymphocytes of 233 mg/kg dose group was higher than that of control group, especially at 1 min(P<0.01).Conclusion Compound Antler capsule can improve NO secretion of macrophages and facilitate the entry of mouse spleen lymphocytes from the G0/G1 into the S phase.It also can increase the [ Ca2 +] i of activated lymphocytes to promote their proliferation.Thus Compound Antler capsule can improve the immune regulating ability.

Objective: To establish the rational drug use standard for elderly hypertensive patients after comprehensive assessment, so as to provide evidence for rational drug use in clinics. Methods: Such standards as Beers, STOPP and START were summarized, key items were extracted,duplicate contents were deleted,and the initial standard was formed and used as the first round questionnaire. The Delphi method was used to conduct the second round expert consultation questionnaire,and the positive coefficients, authority and coordination degree of the experts were evaluated. Results: A total of 10 experts participated in the consultation, and the effective re-covery rate of the second round was 100% and the average authority coefficient was 0. 88. The coordination coefficient of the two rounds was 0. 57 and 0. 76, respectively. The standard of rational drug use for the elderly patients with hypertension after comprehensive as-sessment was finally completed. The standard contained 13 comprehensive assessment contents and 21 drug warning entries. Conclu-sion: After 2 rounds of expert consultation,the opinions tend to be uniform with high degree of coordination. The standard can provide reference for clinicians and clinical pharmacists to use drugs rationally. At the same time,it also provides ideas for the establishment of rational drug use standards for other diseases.
