Abstract:
【Objective】 To study the metabolism and morphology changes of platelets in vitro using traditional Chinese medicine named Qingkailing injection as the additive solution, and to explore the viability of Qingkailing in the extension of platelet storage. 【Methods】 Apheresis platelets, adding 1% final concentration of Qingkailing injection, were taken as experiment groups, and sampled on 1, 3, 5, 8, 10 and 14 days(6 time points)of storage. Apheresis platelets without adding Qingkailing injection were taken as the control, and sampled on 1, 3 and 5 days(3 time points)of storage. The platelet count, morphology scores, biochemical parameters, pH and response rate of hypotonic shock during agitated storage(22 ℃) were tested. 【Results】 1) No significant change in platelet count was noticed in both experimental group(within 14 days) and the control(within 5 days)(P>0.05). The MPV and PDW of both groups increased at any sampling time within 5 days(P<0.05). 2) The morphology score of experimental groups and the control all decreased within the storage period(P<0.05), but its decrease of the control was greater than that of the experimental groups, especially on day 8(P<0.05). 3)Glucose, lactate dehydrogenase, lactate, Na+, and K+ values increased or decreased in varying degrees(P<0.05), while Cl- value stayed almost the same during 14 days(P>0.05). Glucose, lactate dehydrogenase, lactate and Na+ value changed significantly in the control within 5 days(P<0.05), while K+ and Cl- value did not(P>0.05). Within 5-day storage, the glucose consumption, lactate dehydrogenase and lactate generation in the control were significantly greater than those in experimental groups(P<0.05), but the added value of Na+, K+ and Cl- showed no significant difference(P>0.05). 4) pH value, relative to the baseline of day 1, decreased in both groups within 5 days, and its decreasing trend was significant in the control (P<0.05), but not in the experimental group(P>0.05). No significant difference was noticed in the response rate of hypotonic shock in experimental groups within 8 days, while significant decrease was noticed in the control within 5days(P<0.05). The response rate of hypotonic shock in experimental groups were significantly higher than that in the control on day 3 and day 5(P<0.05). 【Conclusion】 The comparison of apheresis platelets, stored in vitro, in terms of platelet count, morphology scores, biochemical parameters, pH and response rate of hypotonic shock showed that platelets, adding 1% final concentration of Qingkailing injection, could prolong the platelet storage to at least 10 days in vitro.
