ABSTRACT

Objective:To construct a Nomogram model in predicting recurrence-free survival (RFS) and overall survival (OS) at six months, one year and two years after hepatocellular carcinoma (HCC) resection by using inflammatory markers combined with other routine clinical indicators.Methods:The data of 314 patients with HCC who underwent first time hepatectomy at Beijing Chaoyang Emergency Rescue Center and Air Force Characteristic Medical Center from January 2013 to January 2018 were analyzed. HCC patients who underwent hepatectomy at the First Medical Center of PLA General Hospital from January 2011 to January 2016 ( n=106) were used as the external validation group. Univariate and multivariate Cox proportional risk model was used to analyze independent risk factors of recurrence and death in HCC patients. A Nomogram model was constructed based on independent risk factors. Validation of the efficacy of the Nomogram model was done based on external data. Results:In the experimental group, 174 patients relapsed. The median RFS was 26 months. The 6 months, 1 year and 2 years RFS were 26.8%, 43.9%, and 68.8%, respectively. A total of 142 patients had died. The median survival time was 30 months. The 6 months, 1 year and 2 years OS were 5.9%, 23.6% and 63.1%, respectively. In the external validation group, 63 patients had developed recurrence, with a median RFS time of 28 months. The 6 months, 1 year and 2 years RFS were 26.4%, 45.3%, 54.7%, respectively. The median survival time was 31 months. The 6 months, 1 year and 2 years OS were 7.5%, 25.5%, 46.6%, respectively. Tumor size (>6.0 cm, HR: 1.447), vascular invasion ( HR: 1.408), TBil (>0.94 mg/dl, HR: 1.949), NLR (>2.54, HR: 2.843), AGR (≤0.88, HR: 2.447) were independent risk factors of HCC recurrence ( P<0.05). Tumor size (>6.0 cm, HR: 2.207), vascular invasion ( HR: 1.529), and NLR (>2.54, HR: 2.708) were independent risk factors of death for HCC patients ( P<0.05). The C-indexes of half-year, one-year and two-year RFS were 0.764 (95% CI: 0.677-0.854), 0.710 (95% CI: 0.615-0.824) and 0.673 (95% CI: 0.601-0.786), respectively. The C-indexes of half-year OS, one-year OS and two-year OS were 0.729 (95% CI: 0.648-0.841), 0.708 (95% CI: 0.608-0.813) and 0.664 (95% CI: 0.618-0.771), respectively. Conclusion:In this study, the construction of a Nomogram model in predicting prognosis of HCC patients was helpful to guide clinicians in improving preoperative treatment plans and in providing ideas for individualized treatment of patients.

ABSTRACT

Objective To analyze the effect of FAM172A protein on HepG2 cell proliferation and related signaling pathways,and provide a theoretical basis for the new target of liver cancer treatment.Methods The liver tissue was removed from March 2016 to February 2018 in the Air Force Characteristic Medical Center (formerly the People's Liberation Army Air Force General Hospital).The liver tissues were surgically resected,including normal liver tissue and liver infected with hepatitis B virus (HBV) tissue and liver cancer tissue,HepG2 cells were randomly divided into experimental group and control group.The experimental group was co-transfected with FAM172A protein granules and fluorescent protein-labeled plasmids,and the control group was left without any treatment.The position of FAM172A protein in HepG2 cells was observed by laser confocal microscopy.The content of FAM172A in LO2,HepG2 and HerpG2.2.15 cells was determined.Different concentrations of FAM172A recombinant protein solution were co-incubated with HepG2 cells for different time.Cell cycle and cell count were detected by flow cytometry,and Notch signal and cyclin expression were detected by Western blot.Results The FAM172A protein was located in the endoplasmic reticulum of HepG2 cells and was clearly expressed in normal liver tissues,and was decreased in liver tissues of patients with HBV infection.With the increase of the concentration of FAM172A,the inhibitory effect on the proliferation of hepatoma cells was more obvious,and it was concentration-dependent.After HepG2 cells were treated with 100 pg/L FAM172A for 48 hours,the percentage in the S phase decreased to 2.27% and in the G1 phase increased to 77.49%,the cell cycle was completely blocked in the G1/S phase.Electrophoresis results showed that only the relative expression of Notch3 protein and cyclin E increased.Conclusion FAM172A may be a novel tumor suppressor gene that inhibits the proliferation of hepatoma cells by activating Notch3 signaling pathway and up-regulating the expression of cyclin E.

ABSTRACT

Liver three-dimensional technology provides decision-making reference for preoperative assessment,intraoperative simulation,and individualized surgical planning.Compared with traditional imaging techniques,the three-dimensional reconstruction technique of the liver performs real-time three-dimensional image analysis of complex liver tissue,and displays the patient's lesions and surrounding organs and blood vessel structures in three dimensions.This technology opened a new page for liver interventional surgery,especially for the successful implementation of trans-jugular intrahepatic portosystemic shunt (TIPS).This article describes the research progress of liver three-dimensional reconstruction technology and its application in TIPS surgery.

ABSTRACT

Objective To explore the relationship among depression,anxiety and social support in elderly patients in community outpatient clinic. Methods A total of 551 elderly outpatients from two com-munity health service centers of Hongkou District in Shanghai were evaluated with patient health question-naire-9 (PHQ-9),generalized anxiety disorder-7 (GAD-7),perceived social support scale( PSSS) for de-pression,anxiety,physical health and social support. Results The prevalence rates of depression and anxiety were 26. 1% and 17. 2%,respectively. The scores of PHQ-9 and GAD-7 were 2. 0(4. 0) and 1. 0(2. 0). There were statistically significant differences in the scores of family support,friend support,other support and social support among the elderly patients with different degrees of depression or anxiety (P<0. 01). Fam-ily support(B=-0. 196) and friend support(B=-0. 171) were protective factors of depression in elderly pa-tients in community outpatient clinic. Age,family support and friend support were protective factors of anxiety in elderly patients,while gender and fluctuation of physical diseases were protective factors of anxiety(P<0. 05). Con-clusions The depression and anxiety is intimately related to social support in elderly outpatients. Appropriate measures should be taken to optimize social support,mitigate bad mood negative improve their quality of life.

ABSTRACT

Objective To investigate the effect of different doses of protamine neutralizing heparin on perioperation of on-pump coronary artery bypass graftting (CABG).Methods A total of 180 on-pump CABG patients hospitalized from January 2015 to November 2016 were randomly divided into three groups,the protamine group l,protamine group 2 and protamine group 3,60 patients in each group.Heparin (3 mg/kg) was used before extracorporeal circulation.After intracardiac operation was over,protamine was used to neutralize the heparin to adjust the activated clotting time (ACT) in protamine group 1,which was 10% higher than that of intubation.Meanwhile,protamine group 2 was neutralized to equal to the ACT before intubation,and protamine group 3 was 10% lower than that before the intubation.The differences of intraoperative and postoperative parameters were compared between the three groups.Results No death was found in the three groups during hospitalization.Comparing with protamine group 1 and protamine group 2,the time of operation,the ACT before the leaving operation room,the ACT of the first hour after returning to ICU,the amount of bleeding during operation,the time of closing and the amount of red blood for transfusion were decreased in protamine group 3 (P > 0.05).The total amount of protamine for neutralizing and the ratio of protamine and heparin were significantly increased in protamine group 3 (P < 0.05).The heart dysfunction after operation,perioperative myocardial infarction,pulmonary edema,pulmonary infection,renal dysfunction,poor wound healing,neurological complications,and time of in hospital stay showed no significant differences between three groups (P>0.05).Conclusion ACT below 10% of preoperation is safe,after neutralization of heparin by protamine,which can obviously reduce the bleeding,the time of sternal closure and the amount of red blood cell transfusion,showing a positive clinical significance.
