Objective To summarize the clinical diagnosis and treatment of nodular regenerative hyperplasia of the liver. Methods Retrospective analysis was made on the clinical manifestations,imagings, laboratory tests, diagnosis, treatment and prognosis of 18 consecutive cases finally established as NRH during the past 26 years. Results 15 of the 18 cases showed portal hypertension, 4 cases showed mono or multiple occupations of the liver, 8 cases suffered from concurrent autoimmune diseases, 3 cases were suspected of blood diseases. Preoperatively, 13 cases were diagnosed as cirrhosis, 2 cases were diagnosed as liver cancer or focal nodular hyperplasia ( FNH). All cases were diagnosed by operative wedging biopsy. 3 cases received splenectomy, 4 cases received disconnection /Phemister surgery, 3 cases received liver occupation/liver lobe resection, 1 case received partial small bowel resection, and 1 case received spleen artery restrictive surgery. Postoperatively, symptoms of portal hypertension relieved obviously. Follow-up study showed most of the patients were stable and prognosis of the NRH was good.Conclusions NRH may relate to the disturbance of liver blood supply, and most common clinical manifestation is portal hypertension, and can combine with immune diseases, hematopathy also can present single or multiple liver occupations. Differential diagnoses include liver cirrhosis, FNH, idiopathic portal hypertension. Diagnosis of NRH relies on liver wedging biopsy. Surgery can relive concurrent portal hypertension.

Objective To investigate the impact of vascular inflow occlusion of the liver on arterial lactate level and pH value. Methods In this study, 68 patients who underwent hepatectomy from January 2006 to December 2008 were retrospectively studied. The patients were assigned to one of the three study groups according the vascular inflow status: clamping of portal vein and hepatic artery in the hepatic pedicle (n = 20), hemihepatectomy under total hemihepatic vascular exclusion (THVE, n = 22), and non-vascular occlusion (n = 26). Postoperative arterial blood gas analysis including systemic arterial lactate concentration, and liver and renal function tests were performed. Results Systemic arterial blood lactate levels significantly elevated in the portal clamping and THVE groups (5.53 ±2. 31 mmol/L and 5.62 ±2.52mmol/L, respectively), compared to the non-occlusion group (3. 37 ± 1.56 mmol/L, P < 0. 05) ;significant increase in arterial HCO3- level was observed in the THVE group in comparison to the nonocclusion group (19. 68 ± 3. 82) mmol/L vs. (21.65 ± 2. 48) mmol/L, (P < 0. 05). There were no significant differences as to the changes of pH values, liver and renal function tests between the three groups. Conclusions Vascular inflow deprivation may result in significantly increased arterial lactate level. Thus, intense surveillance of blood lactate level with prompt treatment is necessary to prevent postoperative hyperlactatemia and metabolic acidosis.

To investigate the effect of preoperative uses of levosimendan in patients with low LVEF(≤0. 40) undergoing off-pump coronary artery bypass grafting(OPCABG). Methods 63 patients with low LVEF coronary artery diseases were prospectively enrolled during June 2015 to May 2018, randomized to levosimendan-treated group(n =32) and control group(n =31)preoperatively. Patients in levosimendan-treated group underwent levosimendan intravenous infusion 24 h before OPCABG. All patients underwent OPCABG at normal temperature. Internal mammary artery and great saphenous vein were used as bypass materials. Hemodynamics and cardiac function were compared between the two groups after OPCABG. Results Compared to control group, the systemic vascular resistance(SVR) and central venous pressure(CVP) of levosimendan- treated group were decreased significantly and the CO and LVEF increased significantly at 12h and 24h after surgery(P < 0. 05). The heart rate and mean artery pressure had no statistical difference between the two groups(P >0. 05). The dosage and administration time of vasoactive agents in levosimendan-treated group were significantly smaller than those in control group (P <0. 05). The time of mechanical ventilation, the ICU stay length, the BNP level in the first two days after operation, and the incidence of new atrial fibrillation were less than those of the control group(P <0. 05). The perioperative intra-aortic balloon pump implantation rate in levosimendan-treated group was significantly lower than that of the control group(P < 0. 05). Conclusion Preoperative use of levosimendan can significantly improve the hemodynamic and cardiac function status of patients with low LVEF after OPCABG, shorten the time of ventilator assisted and ICU hospitalization, and reduce the incidence of adverse events.

To identify the predictors of prolonged mechanical ventilation in patients undergoing surgery for stanford type A acute aortic dissection. Methods 202 patients who underwent surgery for acute aortic dissection type A from May 2009 to May 2016 were divided into two groups based on their mechanical ventilation time after surgery, including 70 patients with mechanical ventilation 48 hours or more(group A), 132 patients with mechanical ventilation less than 48 hours (group B). Univariate and multivariate analysis(logistic regression) were used to identify the predictive risk factors. Results The mechanical ventilation time was(146. 8 ±78. 5)h and(21. 7 ±9. 5)h in group A and group B respectively. Overall inhospital mortality was 8. 6% and 2. 3%. Multivariate logistic analysis showed that BMI(OR = 5. 956, 95% CI: 2. 585 - 13. 723, P =0. 000), CPB time(OR =1. 108, 95%CI: 1. 052 -1. 166, P =0. 000), DHCA(OR =4. 562, 95% CI: 1. 250 - 16. 640, P =0. 022), red blood cell transfusion intraoperative and in 24 hours postoperatively(OR =2. 625, 95% CI: 1. 515 -4. 549, P =0. 001) were the independent predictors for prolonged mechanical ventilation. Conclusion The incidence of prolonged mechanical ventilation is high after surgery for stanford type A acute aortic dissection. It can be predicted based on above factors, for patients with these risk factors, more perioperative care strategies are needed in order to shorten the mechanical ventilation time.

Objective To investigate the effect of postoperative use of levosimendan on patients with valve replacement. Method Patients with valvular diseases who underwent valve replacement were prospectively enrolled during Jan 2014 to May 2018 in Qingdao Municipal Hospital, randomized to a levosimendan-treated group (n=93) and a control group (n=92) preoperatively. Patients in both groups underwent the same routine treatment preoperatively and postoperatively. In addition, patients in the levosimendan-treated group underwent levosimendan intravenous infusion 24 hours after entering ICU postoperatively. The clinical effect of the two groups was compared. Results Compared to the control group, the cardiac output(CO, 5.2±1.0 L/min vs. 4.4±1.1 L/min on the seventh day after surgery) and left ventricular ejection fraction (LVEF, 55.7%±2.5% vs. 50.5%±2.2% on the seventh day after surgery) of levosimendan-treated group were increased significantly at different time points(1 day, 3 days and 7 days after surgery)(P<0.05), and the brain natriuetic peptid (BNP) level (312.5±34.6 pg/ml vs. 455.4±45.2 pg/ml on the seventh day after surgery) was less than that of the control group (P<0.05). The dosage (11.5±1.8 mg/kg vs. 20.4±2.1 mg/kg) and administration time of vasoactive agents in the levosimendan-treated group were significantly lower or shorter than those in the control group (70.4±11.2 h vs. 110.5±12.1 h, P<0.05). The ICU stay length, and the total incidence of adverse events were less than those of the control group (P<0.05). Conclusion Postoperative use of levosimendan immediately after surgery can significantly improve the cardiac function status of patients who underwent valve replacement, reduce the dosage of vasoactive agents, shorten the time of ICU hospitalization, reduce the incidence of adverse events and enhance the patient’s recovery after valve replacement.
