Objective To determine intra-operative changes in blood coagulation and the applicability of SCA in liver transplantation. Methods Twenty-four patients with end-stage liver disease undergoing or-thotopic Liver transplantation (OLT) were studied. Arterial blood samples were drawn for determination of celite-activated TEG, glass bead-activated SCA and RCT at 6 intervals: before anesthesia induction (T0), 60 min after operation was started (T1), 30 miu in anhepatic phase (T2), 30 min in neohepatic phase (T3) ,120 min in neohepatic phase (T4) and the end of the operation (T5) ; the variables of TEG includ-ed: reaction time(R) ,coagulation time(K), alpha angles (α) and maximal amplitude (MA) ; the variables of SCA included: activated clotting time (ACT), clot rate (CR) and platelet function(PF) ;RCT included: Plt, PT, INR, APTT, Fbg. Results The Kappa values of SCA and TEG diagnosing the deficiency of blood coagulation factors, the gel formation speed of fibrin and the function of platelet were respectively 0.371 (P < 0.05) ,0. 363 (P < 0.05) ,0.438 (P < 0.05). gbACT and R, CR and α, PF and MA were positive-ly correlative (r = 0. 790, P < 0.05 ; r = 0. 766, P < 0. 05 ; r = 0. 502, P < 0.05 ; respectively) ; CR and K were negatively correlative(r = -0. 588,P <0.05). Compared with T0, PT, INR, gbACT and R were pro-longed, FBG, CR, α and MA were decreased at T3-5 (P < 0.05). APTT was prolonged at T1 ～ T5 (P < 0.05). K was prolonged at T3 (P < 0.05) and PF was decreased at T2 ～ T4. Conclusion SCA can exactly monitor changes of blood coagulation in liver transplantation.

Objective To compare the laryngeal mask insertion conditions at different plasma target concentrations (Cp) during the induction of anesthesia with target-controlled infusion (TCI) of propofol.Methods Forty-five ASA I - II patients of both sexes aged 18-60 yr, weighing 50-80 kg undergoing minor surgery in which the use of laryngeal mask (LM) was indicated were randomly divided into 3 groups ( n = 15) according to Cp of propofol set during induction of anesthesia: 4, 6 and 8 ?g ? ml-1 . The patients were premedicated with intramuscular scopolamine 0.3 mg. Fentanyl 3 ?g?kg-1 was given i.v. . TCI of propofol was started 3 min later with Diprifusor (Graseby 3500 infusion pump). LM was inserted when the effect-site concentration (EC) of propofol reached 2.5 ?g ? ml -1 as displayed on the infusion pump. LM insertion conditions (mouth opening, gagling, coughing, head and limb movement, overall ease of insertion) were assessed. The total dose of propofol, insertion time, the time needed to reach EC 2.5 ?g?ml-1 were recorded. SP, DP, HR and BIS value were recorded at 6 time points: baseline before induction (T1 ) , at the loss of consciousness (T2), at EC 2.5 ?g ? ml-1 (T3), immediately (T4), 3 min (T5) after insertion of LM. Results The SP, DP, HR and BIS value were decreasing with increasing depth of anesthesia in the 3 groups. The decrease in BP and BIS value after insertion of LM was significantly larger in group 3 (8 ?g ?ml-1) than in group 1 and 2 (P

Yinchenzhufu decoction (YCZFD) is a classic formula for treating Yin Huang syndrome, which can improve liver injury caused by cholestasis. However, the mechanism of action of YCZFD still remains unclear. This article used network pharmacology, molecular docking, animal experiments, and molecular biology methods to explore the mechanism of YCZFD in treating liver injury caused by cholestasis. A mouse model of acute cholestasis induced by lithocholic acid was used to investigate the effects of YCZFD on liver injury. The experimental procedures described in this paper were reviewed and approved by the Ethical Committee at the Shanghai University of Traditional Chinese Medicine (approval NO. PZSHUTCM190823002). The results showed that YCZFD could reduce the levels of blood biochemical indicators and improve hepatocyte damage of cholestatic mice. Then, multiple databases were used to predict the corresponding targets of YCZFD active components on cholestatic liver injury. An intersection target protein-protein interaction (PPI) networks based on String database and Cytoscape software was used to demonstrate the possible core targets of YCZFD against cholestatic liver injury. The results indicated that core targets of YCZFD include tumor necrosis factor, interleukin-1β, non-receptor tyrosine kinase Src, interleukin-6, etc. GO (gene ontology) and KEGG (kyoto encyclopedia of genes and genomes) enrichment analysis indicated that YCZFD may regulate the tumor necrosis factor signaling pathway, nuclear factor-κB signaling pathway, bile secretion, and other related factors to ameliorate the cholestatic liver injury. AutoDockTools software was used to perform molecular docking verification on the core targets and components of YCZFD. To verify the results of network pharmacology, UPLC-MS/MS method was used to determine the effect of YCZFD on levels of bile acid profiles in mouse liver tissues. It was found that treatment with YCZFD significantly reduced the content of free bile acids, taurine bound bile acids, and total bile acids in the liver tissues of cholestatic mice. Then, results from real time PCR and Western blot also found that YCZFD can upregulate the expression of hepatic nuclear receptor farnesoid X receptor, metabolizing enzyme (UDP glucuronidase transferase 1a1), and efflux transporters (bile salt export pump, multidrug resistance-associated protein 2, multidrug resistance-associated protein 3, etc) in cholestasis mice, promote bile acid metabolism and excretion, and improve bile acid homeostasis. Moreover, YCZFD can also inhibit pyroptosis and inflammation by regulating NOD-like receptors 3 pathway, thereby inhibiting cholestatic liver injury.
