Effect of ligustrazine hydrochloride on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To observe the protection effect of Ligustrazine Hydrochloride (LH) on coagulation reaction and inflammation reaction in single valve replacement patients with rheumatic heart disease undergoing cardiopulmonary bypass (CPB).</p><p><b>METHODS</b>Totally 40 patients undergoing single valve replacement were recruited in the study and randomly assigned to the two groups, the treatment group and the control group, 20 in each group. In treatment group LH (3 mg/kg) was intravenously infused from the jugular vein. LH (3 mg/kg) was also added in the CPB priming. In the control group LH was replaced by equal amount of normal saline. Endothelial micro-particles (EMP) count was detected before CPB, 30 min after CPB, 1 h and 24 h after CPB finished. The coagulation reaction time (R), coagulation time (K), clotting formation velocity (alpha angle), maximum amplitude (MA), coagulation index (CI), platelet (PLT), hypersensitive C reactive protein (hs-CRP), IL-6, and IL-10 were detected before CPB, 1 h and 24 h after CPB finished.</p><p><b>RESULTS</b>There was no statistical difference in aorta arresting time, period of CPB, post-operative drainage volume, plasma transfusion volume, post-operative respirator assistant time, and hospitalization time between the two groups (P >0.05). Compared with pre-CPB in the same group, the count of EMP was much higher at 30 min after CPB and 1 h after CPB finished (P < 0.01). R and K, hs-CRP, IL-6, and IL-10 increased at 1 h and 24 h after CPB finished (P <0.01,P < 0.05). The alpha angle,.MA, CI, and PLT decreased 1 h after CPB finished (P <0.01). The a angle increased, while CI and PLT decreased 24 h after CPB finished (P <0.05). Compared with the control group in the same period, the count of EMP was lower in the treatment group 30 min after CPB and 1 h after CPB finished (P <0. 05, P <0. 01). R and K values obviously decreased in treatment group 1 hour after CPB finished (P <0. 05), while a angle, MA, CI, and PLT increased (P <0. 05, P <0. 01). hs-CRP and IL-6 decreased in the treatment group 1 h and 24 h after CPB finished (P <0.05), while IL-10 increased (P <0.05). The count of PLT increased 24 h after CPB finished in the treatment group (P <0. 05).</p><p><b>CONCLUSION</b>LH had certain protection effect on the vascular endothelium undergoing CPB, and lower excessive activation of coagulation reaction and inflammation reaction in patients undergoing CPB.</p>

Development of POCT and medical digital assistant for primary medical healthcare / 中国医疗器械杂志

In this paper, we discuss the meaning, advantages and methods of applying the point of care testing (POCT) and medical digital assistant (MDA) to primary healthcare services. We also introduce the development of the POCT and MDA based on the electronic health record(EHR) system.
