ABSTRACT
@#Objective To research the influence of anticoagulation to blood clotting function in patients who experienced cardiopulmonary bypass surgery under continuous renal replacement therapy (CRRT) with regional citrate anticoagulation (RCA), low molecular weight heparin (LMWH) anticoagulation and non-anticoagulation. Methods We retrospectively analyzed the clinical data of 146 patients who underwent CRRT after cardiopulmonary bypass surgery between January 2014 and December 2016. There were 98 males and 48 females at age of 60.51±14.29 years. All CRRT patients were allocated into three groups including a RCA group, a LMWH group, and a non-anticoagulation group, which were compared in terms of convention coagulation tests, platelet counts, thromboelastography, circuit lifespan and transfusion. Results Three hundred and fifty four CRRT patients were selected from patients above, including 152 patients in the LMWH group, 160 in the RCA group, and 42 in the non-anticoagulation group. The difference of CRRT circuits time among three groups was statistically different (P=0.023). And multiple comparison showed that the circuit lifespan of the RCA group was significantly longer than that of the non-anticoagulation group (34.50 h ranged 14.00 h to 86.00 h vs.15.00 h ranged 12.00 h to 50.88 h, P=0.033). One hundred and fifty-five CRRT patients last beyond 24 hours with same anticoagulation were selected, the results of coagulation tests, and the difference between CRRT starting and after 24 hours were compared. The difference of Angle and maximum amplitude(MA) of pre- and post-CRRT were significantly different among three groups by one-way ANOVA (P=0.004, 0.000), as well as between the RCA group and the LMWH group by multiple comparison (P=0.004, 0.000). There was no statistical difference in frequencies and doses of the transfusion of fresh frozen plasma and platelet among three groups. Conclusion RCA is an effective anticoagulation which may prolong circuit lifespan and has small impact on the coagulation function of patients who undergo CRRT after cardiopulmonary bypass surgery.
ABSTRACT
<p><b>OBJECTIVE</b>To explore Chinese medicine (CM) syndrome distribution of chronic hepatitis B virus (HBV) carriers in immunotolerant phase (ITP).</p><p><b>METHODS</b>One hundred and eighty-five chronic HBV carriers in ITP, seen in the Third Affiliated Hospital of Sun Yat-sen University from May 2009 to December 2010, were admitted in an observational study under the guidance of CM. Patients' CM symptoms and signs, demographics, liver biochemistries, and qualitative HBV DNA were recorded in the questionnaires. CM syndromes were then differentiated to 15 detailed types and analyzed by generalization. Lastly, the location, pathogenic factors and nature of the disease were also assessed.</p><p><b>RESULTS</b>When CM syndrome patterns were differentiated to 15 types, there were 27 (15%) no syndrome cases, 94 (50%) single syndrome cases and 64 (35%) compound syndromes cases. The main detailed syndromes included Liver (Gan)-qi depression (LQD), Kidney (Shen)-qi deficiency (KQD), Spleen (Pi)-qi deficiency (SQD) and Kidney-yang deficiency (KYAD). After CM syndromes generalized to five types, their frequency was Spleen-Kidney deficiency (SKD)>LQD>inner dampness-heat retention (IDHR)>Liver-Kidney deficiency (LKD)>blood stasis blocking collateral (BSBC). SKD and LQD occupied 64%. The disease location included Liver, Gallbladder (Dan), Spleen, Stomach (Wei) and Kidney. The pathogenic factors were mainly qi stagnation, qi deficiency, yang deficiency, concurrently dampness-heat and blood stasis. The deficiency syndrome was more than excess syndrome in its nature.</p><p><b>CONCLUSIONS</b>Most of chronic HBV carriers in ITP have their CM syndrome, and the most common types are SKAD, LQD. This study suggests that the natural history may be improved through breaking the state of immune tolerance or shorten the time of ITP by strengthening Spleen-Kidney and reliving Liver qi.</p>
