Objective To investigate the risk factors resulting in the perioperative liver failure and death for the HBV-associated hepatocellular carcinoma (HCC) patients with or without cirrhosis.Methods The method of retrospective case-control study was performed.The clinicopathological data of 1 083 HCC patients with positive HBsAg who received curative liver resection at the Southwest Hospital from January 2008 to December 2012 were collected.According to the absence or presence of cirrhosis,the HCC patients with positive HBsAg were divided into the 2 groups,including the cirrhosis group (633 patients) and the non-cirrhosis group (450patients).The intraoperative conditions (operation time,volume of intraoperative blood loss,rate of blood transfusion,rate of pringle maneuver) and postoperative conditions (incidence of perioperative complications,duration of postoperative hospital stay,perioperative mortality) of HCC patients were observed.The gender,age,alanine transaminase (ALT),aspartate transaminase (AST),albumin (Alb),total bilirubin (TBil),platelet (PLT),Child-Pugh classification,operation time,volume of intraoperative blood loss,blood transfusion,pringle maneuver,extent of liver resection,number of tumors,tumor diameter,tumor thrombus and liver cirrhosis were enrolled and prognostic factors resulting in perioperative liver failure and death for the HCC patients were explored.Measurement data with skewed distribution were presented as M (range) and comparison between the 2 groups was analyzed using Mann-Whitney U test.Count data were presented as counts (percentage) and comparison between the 2 groups was analyzed using chi-square test or Fisher exact probability.Univariate analysis was performed by chi-square test and multivariate analysis was performed by Logistic regression model (forward).Results (1) The intraoperative conditions:the volume of intraoperative blood loss were 500 mL (range,30-7 000 mL) in the cirrhosis group and 400 mL (range,50-8 000 mL) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (Z =-2.209,P ＜ 0.05).The operation time,rate of blood transfusion and rate of pringle maneuver were 250 minutes (range,82-715 minutes),29.86％ (189/633),62.24％ (394/633) in the cirrhosis group and 242 minutes (range,85-738 minutes),27.11％ (122/450),66.67％ (300/450) in the non-cirrhosis group,respectively,with no statistical differences between the 2 groups (Z =-1.212,x2 =0.969,2.236,P ＞0.05).(2) The postoperative conditions:the incidence of perioperative complications was 30.49％(193/633) in the cirrhosis group and 21.11％ (95/450) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (x2 =11.851,P ＜ 0.05).The incidence of lung infection,abdominal infection and liver failure were 6.48％ (41/633),2.69％ (17/633),5.53％ (35/633) in the cirrhosis group and 3.56％ (16/450),0.89％ (4/450),1.33％ (6/450) in the non-cirrhosis group,respectively,with statistically significant differences between the 2 groups (x2 =4.502,4.465,12.713,P ＜ 0.05).The duration of postoperative hospital stay was 15 days (range,0-70 days) in the cirrhosis group and 14 days (range,0-71 days) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (Z =-3.448,P ＜ 0.05).The perioperative mortality was 5.85％ (37/633) in the cirrhosis group and 2.44％ (11/450) in the non-cirrhosis group,with a statistically significant difference between the 2 groups (x2=7.181,P ＜ 0.05).(3)Results of risk factors affecting perioperative liver failure:①results of univariate analysis showed that age,AST,Alb,Child-Pugh classification,operation time,volume of intraoperative blood loss,blood transfusion,extent of liver resection,tumor diameter,liver cirrhosis with positive HBsAg were associated with perioperative liver failure in HCC patients (x2=5.013,7.979,8.855,16.968,14.148,9.764,18.511,11.749,5.534,12.713,P＜0.05);age,AST,Alb,Child-Pugh classification,operation time,blood transfusion,extent of liver resection and tumor diameter were associated with perioperative liver failure in the cirrhosis group (x2=5.877,5.380,11.087,13.672,8.849,13.170,12.418,5.805,P ＜ 0.05);volume of intraoperative blood loss was associated with perioperative liver failure in the non-cirrhosis group (P ＜ 0.05).②Results of multivariate analysis showed that age≥60 years,Child-Pugh class B,operation time ＞ 360 minutes,blood transfusion,extent of liver resection ≥3 segments and liver cirrhosis were independent risk factors affecting perioperative liver failure in HCC patients with positive HBsAg [OR =2.285,2.716,2.315,2.159,2.459,4.322;95％ confidence interval (CI):1.081-4.831,1.100-6.706,1.064-5.038,1.068-4.362,1.264-9.786,1.763-10.598,P＜0.05];Alb ＜38 g/L,Child-Pugh class B,blood transfusion and extent of liver resection ≥ 3 segments were independent risk factors affecting perioperative liver failure in the cirrhosis group (OR =2.231,2.857,2.186,2.927,95％ CI:1.038-4.795,1.095-7.451,1.045-4.576,1.426-6.008,P ＜ 0.05);volume of intraoperative blood loss ＞ 1 200 mL was an independent risk factor affecting perioperative liver failure in the non-cirrhosis group (OR =15.077,95％CI:2.695-84.353,P ＜ 0.05).(4) Risk factors affecting perioperative death:①results of univariate analysis showed that gender,Alb,TBil,Child-Pugh classification,blood transfusion,extent of liver resection,tumor diameter,tumor thrombus and liver cirrhosis were associated with perioperative death in HCC patients with positive H BsAg (x2=4.462,8.783,4.212,4.869,7.189,11.745,6.837,4.323,7.181,P ＜0.05);Alb,extent of liver resection and tumor diameter were associated with perioperative death in the cirrhosis group (x2=12.173,12.793,10.981,P ＜ 0.05);blood transfusion and tumor thrombus were associated with perioperative death in the non-cirrhosis group (x2 =5.836,6.417,P ＜ 0.05).② Results of multivariate analysis showed that Alb ＜38 g/L,extent of liver resection ≥ 3 segments and liver cirrhosis were independent risk factors affecting perioperative death in HCC patients with positive HBsAg (OR =2.560,2.657,2.567,95％ CI:1.382-4.742,1.471-4.800,1.283-5.134,P ＜ 0.05);Alb ＜ 38 g/L,extent of liver resection ≥ 3 segments and tumor diameter≥5 cm were independent risk factors affecting perioperative death in the cirrhosis group (OR =3.003,2.533,3.060,95％ CI:1.495-6.034,1.251-5.128,1.135-8.251,P＜0.05);blood transfusion and tumor thrombus were

for perioperative liver failure and death in HCC patients with positive HBsAg.The risk of perioperative liver failure and death in HCC patients with cirrhosis is significantly higher than that in HCC patients without cirrhosis,and there is a difference in the risk factors for perioperative liver failure and death.

Objective To investigate the association between body weight daily fluctuation and prognosis in severe trauma patients and evaluate the values of dynamical monitoring of early weight change in treatment of severe trauma.Methods A prospective cohort study was made on 65 patients with severe trauma treated between June 2015 and December 2015.There were 41 males and 24 females,with age of (54 ± 17)years.When admitted to the emergency intensive care unit (EICU),the patients were with body mass index (BMI) for (22.0 ±2.7) kg/m2,injury severity score (ISS) for (22 ±5) points,as well as acute physiology and chronic health evaluation (APACHE) Ⅱ for (15 ± 6)points.According to the survival status during hospitalization,the patients were distributed to death group (9 patients) and survival group (56 patients).Daily body weight was measured from admission by using a weighing scale to evaluate the difference of daily body weight change between two groups.The correlation between daily body weight change and volume change as well as the relationship between daily body weight change tendency and prognosis were evaluated.Results Overall,the variation of weight was negatively correlated with ICU stay in two groups.The weight variations in death group and survival group were 0.4 (0.2,0.8) kg and-0.2 (-0.7,0.2) kg,respectively (P ＜ 0.01).The cumulative weight variation between two groups within one week was 5.02 kg (95％ CI 3.97-6.07,P ＜0.01).The change of body weight was moderately correlated with corresponding fluid balance (r =0.69,P ＜ 0.01).According to the Logistic regression analysis,daily weight gain within one week was found to be positively associated with ICU mortality (OR =3.05,P ＜ 0.05).Conclusions The body weight is negatively correlated with ICU stay in severe trauma patients.The body weight change within one week in EICU is closely correlated with fluid balance and body weight increase may elevate the risk of ICU mortality.

OBJECTIVE: To analyze the effect of mechanical cardiopulmonary resuscitation (CPR) on patients with cardiac arrest with the vertical spatial pre-hospital emergency transport. METHODS: A retrospective cohort study was conducted. The clinical data of 102 patients with out-of-hospital cardiac arrest (OHCA) who were transferred to the emergency medicine department of Huzhou Central Hospital from the Huzhou Emergency Center from July 2019 to June 2021 were collected. Among them, the patients who performed artificial chest compression during the pre-hospital transfer from July 2019 to June 2020 served as the control group, and the patients who performed artificial-mechanical chest compression (implemented artificial chest compression first, and implemented mechanical chest compression immediately after the mechanical chest compression device was ready) during pre-hospital transfer from July 2020 to June 2021 served as the observation group. The clinical data of patients of the two groups were collected, including basic data (gender, age, etc.), pre-hospital emergency process evaluation indicators [chest compression fraction (CCF), total CPR pause time, pre-hospital transfer time, vertical spatial transfer time], and in-hospital advanced resuscitation effect evaluation indicators [initial end-expiratory partial pressure of carbon dioxide (P_ETCO₂), rate of restoration of spontaneous circulation (ROSC), time of ROSC]. RESULTS: Finally, a total of 84 patients were enrolled, including 46 patients in the control group and 38 in the observation group. There was no significant difference in gender, age, whether to accept bystander resuscitation or not, initial cardiac rhythm, time-consuming pre-hospital emergency response, floor location at the time of onset, estimated vertical height, and whether there was any vertical transfer elevator/escalator, etc. between the two groups. In the evaluation of the pre-hospital emergency process, the CCF during the pre-hospital emergency treatment of patients in the observation group was significantly higher than that in the control group [69.05% (67.35%, 71.73%) vs. 61.88% (58.18%, 65.04%), P < 0.01], the total pause time of CPR was significantly shorter than that in the control group [s: 266 (214, 307) vs. 332 (257, 374), P < 0.05]. However, there was no significant difference in the pre-hospital transfer time and vertical spatial transfer time between the observation group and the control group [pre-hospital transfer time (minutes): 14.50 (12.00, 16.75) vs. 14.00 (11.00, 16.00), vertical spatial transfer time (s): 32.15±17.43 vs. 27.96±18.67, both P > 0.05]. It indicated that mechanical CPR could improve the CPR quality in the process of pre-hospital first aid, and did not affect the transfer of patients by pre-hospital emergency medical personnel. In the evaluation of the in-hospital advanced resuscitation effect, the initial P_ETCO₂ of the patients in the observation group was significantly higher than that of the patients in the control group [mmHg (1 mmHg ≈ 0.133 kPa): 15.00 (13.25, 16.00) vs. 12.00 (11.00, 13.00), P < 0.01], the time of ROSC was significantly shorter than that in the control group (minutes: 11.00±3.25 vs. 16.64±2.54, P < 0.01), and the rate of ROSC was slightly higher than that in the control group (31.58% vs. 23.91%, P > 0.05). It indicated that continuous mechanical compression during pre-hospital transfer helped to ensure continuous high-quality CPR. CONCLUSIONS Mechanical chest compression can improve the quality of continuous CPR during the pre-hospital transfer of patients with OHCA, and improve the initial resuscitation outcome of patients.

Objective To investigate the correlation between angiopoietin-2(Ang-2)and intestinal fatty acid binding protein(I-FABP)levels and the prognosis of acute myocardial infarction(AMI)with cardiac shock(CS).Methods A total of 198 patients with AMI admitted to Huzhou Central Hospital from July 2017 to July 2019 were selected as study objects,and were divided into CS group(n=93)and non-CS group(n=105)according to whether CS occurred during the hospital period,and 65 normal volunteers admitted for physical examination during the same period were included in control group.Patients in CS group were divided into survival group(n=50)and death group(n=43)according to their survival at 28 days.Serum Ang-2 and I-FABP levels of all subjects were detected,and Cox regression analysis was used to analyze the factors affecting the poor prognosis of AMI with CS.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of Ang-2 and I-FABP in AMI with CS.Results Serum Ang-2 and I-FABP levels in CS group were significantly higher than those in non-CS group and control group(P<0.05),and serum Ang-2 and I-FABP levels in non-CS group were significantly higher than those in control group(P<0.05).Serum Ang-2,I-FABP levels and proportion of diabetes in death group were significantly higher than those in survival group(P<0.05).Cox regression analysis showed that diabetes,Ang-2 and I-FABP levels were independent factors affecting the prognosis of AMI with CS(P<0.05).ROC curve showed that the area under the curve of Ang-2 and I-FABP combined to predict the prognosis of AMI with CS was 0.819,sensitivity was 81.4%,specificity was 80.0%.Conclusion Serum Ang-2 and I-FABP levels were elevated in patients with AMI with CS,which were potential biological indicators to predict the prognosis of patients.

Objective: To investigate the resuscitation effect of aortic balloon occlusion (ABO) on the traumatic cardiac arrest (TCA) in swine. Methods: Twenty-seven male domestic swine weighing (32.7±3.8)kg were utilized. After 40% of estimated blood volume was removed within 20 minutes, the animals were subjected to 5 minutes of untreated ventricular fibrillation and then 5 minutes of cardiopulmonary resuscitation. Additionally, fluid resuscitation was initiated coincident with the beginning of cardiopulmonary resuscitation. The animals were randomly divided into model group (n=12) and ABO group (n=15). Once cardiopulmonary resuscitation was implemented, aortic balloon was concurrently inflated to stop the blood flow of descending thoracic aorta at the level of the diaphragm in the ABO group. In the model group, aortic balloon was placed in the same position without inflation. During cardiopulmonary resuscitation, the changes of coronary perfusion pressure (CPP), forehead's regional cerebral oxygen saturation (rSO₂) and pressure of end-tidal CO₂ (PETCO₂) were continuously monitored, and the rate of return of spontaneous circulation (ROSC), duration of cardiopulmonary resuscitation, number of shocks and dose of epinephrine were recorded. At 5 minutes after successful resuscitation, the levels of arterial blood gas, lactate and jugular venous blood oxygen saturation (SjvO₂) were measured. Results: Compared with the model group, the values of CPP, rSO₂ and PETCO₂ during cardiopulmonary resuscitation were significantly increased in the ABO group [CPP: (33.5±5.6)mmHg vs. (23.1±5.2)mmHg at 1 minute, (35.3±6.0)mmHg vs. (26.8±7.4)mmHg at 2 minutes, (36.3±6.3)mmHg vs. (28.2±6.3)mmHg at 3 minutes, (40.1±7.1)mmHg vs. (30.5±6.2)mmHg at 4 minutes, (38.1±7.5)mmHg vs. (29.8±5.3)mmHg at 5 minutes; rSO₂: (45.4±5.2)% vs. (39.2±5.1)% at 1 minute, (47.2±3.6)% vs. (42.0±6.4)% at 2 minutes, (47.7±3.0)% vs. (41.5±5.4)% at 3 minutes, (47.0±2.5)% vs. (42.1±5.9)% at 4 minutes, (47.1±2.0)% vs. (41.5±7.4)% at 5 minutes; PETCO₂: (17.0±3.5)mmHg vs. (12.7±4.2)mmHg at 1 minute, (18.5±3.7)mmHg vs. (14.5±2.7)mmHg at 2 minutes, (20.7±5.3)mmHg vs. (15.5±3.2)mmHg at 3 minutes, (18.7±4.5)mmHg vs. (14.9±3.5)mmHg at 4 minutes, (18.2±3.2)mmHg vs. (14.5±4.2)mmHg at 5 minutes] (all P<0.05). The rate of ROSC was significantly higher in the ABO group than in the model group[100%(15/15) vs. 75%(9/12)] (P<0.05). Additionally, shorter duration of cardiopulmonary resuscitation, less number of shocks and lower doses of epinephrine were observed in the ABO group when compared with the model group[duration of cardiopulmonary resuscitation: 5(5, 5)minutes vs. 5(5, 12.5)minutes, number of shocks: 1(1, 1)times vs. 1(1, 4)times, dose of epinephrine: 0.62(0.62, 0.74)mg vs. 0.64(0.59, 2.59)mg] (all P<0.05). At 5 minutes after resuscitation, the level of arterial lactate was significantly decreased and the value of SjvO₂ was significantly increased in the ABO group compared with the model group[Lactate: (9.6±0.8)mmol/L vs. (10.8±1.4)mmol/L; SjvO₂: (50.0±8.6)% vs. (37.9±16.3)%] (both P<0.05). Conclusions In a swine model of TCA, ABO can increase cardiac and cerebral perfusion during cardiopulmonary resuscitation and improve the efficacy of cardiopulmonary resuscitation. It might provide a novel and effective method for the resuscitation of TCA in the clinical setting.
