International Journal of Surgery 2010;37(1):38-40
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-1

Objective To discuss the feasibility and safety of continuous spinal anesthesia (CSA) in renal transplantation through comparing the effects of combined spinal and epidural anesthesia (CSEA) and CSA renal transplantation. Methods Sixty patients undertaking renal transplantation were divided into two groups randomly. Group A, 30 patients, undertaking operation with CSEA; Group B, 30 patients, undertaking operation with CSA. The patients in group A were injected 2 mL 0.75% ropivacaine, then epidural catheter was inserted, 0. 75% ropivacaine 10 mL was administered when needed. The patients in group B were injected 2 mL 0.75% ropivacaine into spinal through Spinocath catheter, and 0.75% ropivacaine 1ml was administered through Spinocath catheter when needed. We observed the effects of the two anesthesia methods and the changes of the patients' vital signs. Results The patients in group A and B all completed the operation smoothly; there were no significant differences in the circulatory function before and during operation; there were no complications related to anesthesia in all the patients; group B was superior to group A in the aspects of the control and maintaining of anesthesia. Conclusion Continuous spinal anesthesia applied to renal transplantation is safe and feasible.

Prepulse inhibition ( PPI) is the suppression of the startle reflex when the startling stim-ulus is preceded by a non-startling stimulus ( the prepulse) . It is an operational measurement of sensorimotor gating mechanism to help the brain adapt to the complex environment,which could be top-down modulated by attention and other higher cognitive processes. Deficits of PPI and the top-down modulation of PPI are closely related to psychiatric diseases. Research papers published from January 2001 to October 2016 related to PPI in psychiatric disorders were searched in the Chinese and English databases. Results showed that schizo-phrenic patients and their relatives showed deficits in baseline PPI as well as the attentional modulation of PPI,and more importantly,the attentional modulation of PPI rather than the baseline PPI was more related to the symptom severity. Patients with Tourette'' s syndrome showed PPI impairment,while patients with obsess-ive compulsive disorder had lower levels of PPI. PPI deficits in bipolar disorder patients were gender-depend-ent. Studying PPI and the top-down modulation of PPI could provide a basis to study the interaction of senso-ry processing and attention,and facilitate the researches of neural mechanism underlying the deficits of senso-ry gating. To establish advanced paradigms of PPI,new cognitive components could be introduced,such as at-tention,emotion,motor control,compulsivity and so on,thus improving the specificity of PPI test and promo-ting the PPI test as new biomarker and endophenotype in various psychiatric disorders.
