Purpose: Liver cancer, one of the most common cancers in China, is reported to feature relatively high morbidity and mortality. Curcumin (Cum) is considered as a drug possessing anti-angiogenic, anti-inflammation and anti-oxidation effect. Previous research has demonstrated antitumor effects in a series of cancers. Materials and Methods: In this study the in vitro cytotoxicity of Cum was measured by MTT assay and pro-apoptotic effects were assessed by DAPI staining and measurement of caspase-3 activity. In vivo anti-hepatoma efficacy of Cum was assessed with HepG2 xenografts. Results: It is found that Cum dose-dependently inhibited cell growth in HepG2 cells with activation of apoptosis. Moreover, Cum delayed the growth of liver cancer in a dose-dependent manner in nude mice. Conclusions: Cum might be a promising phytomedicine in cancer therapy and further efforts are needed to explore this therapeutic strategy.

Background/Aims: With improvements in the survival of liver transplantation (LT) recipients, the focus is shifting to patient quality of life (QOL), and employment is an important factor in aiding the social reintegration of LT patients. This study aims to evaluate the current employment status of liver graft recipients and various factors that may hinder reemployment. Methods: Fifty patients above age 18 who underwent either living or deceased donor LT at a single center from March 2009 to July 2016 were interviewed during their visit to the outpatient clinic. The internally developed questionnaire consisted of 10 items. The Karnofsky Performance Scale and EQ-5D were used to evaluate patient function and QOL. Results: A total of 25 (50%) patients returned to work after transplantation (the working group), and 21 (84%) patients in the working group returned to work within the first year after transplantation. In the non-working group (n=25), 17 (68%) answered that their health was the reason for unemployment. Fatigue and weakness were the most frequent symptoms. Conclusions: The data shows that as many as 50% of total patients returned to work after receiving LT. Fatigue and weakness were the most common complaints of the unemployed group, and resolving the causes of these symptoms may help to increase the employment rate.

Purpose: The purpose of this longitudinal study was to identify the relationship between the readiness for hospital discharge and self-care changes in an early stage of liver transplantation after discharge. Methods: Data of 75 liver transplant recipients within one year of surgery from a transplantation center from May 2019 to May 2020 were collected for this study. Their readiness for discharge was measured before discharge. Self-care after liver transplantation was evaluated at one week, one month, and three months of discharge at outpatient visits. Linear mixed model was used to evaluate the statistical relationship. Results: The readiness for hospital discharge was significantly higher when the caregiver was a spouse (p=.027), with fewer post-transplantation days (p=.027), absence of acute rejection (p=.004), or high self-efficacy (p<.001). As a result of the linear mixed model analysis, the higher the discharge readiness score, the higher the self-care score (β=0.29, p<.001). However, after three months, their self-care had decreased regardless of their level of readiness for hospital discharge compared to one week after discharge. Conclusion: Improving the readiness before discharge is essential to enhance self-care. Also, active intervention at 3 months of discharge should be performed to check and promote their long-term self-care.

Objective: To investigate whether the diagnostic performance of CT angiography (CTA) could be improved by modifying the conventional criterion (anastomosis site abnormality) to diagnose hepatic artery occlusion (HAO) after liver transplantation (LT) in suspected patients with Doppler ultrasound (US) abnormalities. Materials and Methods: One hundred thirty-four adult LT recipients (88 males and 46 females; mean age, 52.7 years) with suspected HAO on Doppler US (40 HAO and 94 non-HAO according to the reference standards) were included. We evaluated 1) abnormalities in the HA anastomosis, categorized as a cutoff, ≥ 50% stenosis at the anastomotic site, or diffuse stenosis at both graft and recipient sides around the anastomosis, and 2) abnormalities in the distal run-off, including invisibility or irregular, faint, and discontinuous enhancement. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy of the conventional (considering anastomosis site abnormalities alone) and modified CTA criteria (abnormalities in both the anastomosis site and distal run-off) for the diagnosis of HAO were calculated and compared using the McNemar test. Results: By using the conventional criterion to diagnose HAO, the sensitivity, specificity, PPV, NPV, and accuracy were 100% (40/40), 74.5% (70/94), 62.5% (40/64), 100% (70/70), and 82.1% (110/134), respectively. The modified criterion for diagnosing HAO showed significantly increased specificity (93.6%, 88/94) and accuracy (93.3%, 125/134) compared to that with the conventional criterion (p = 0.001 and 0.002, respectively), although the sensitivity (92.5%, 37/40) decreased slightly without statistical significance (p = 0.250). Conclusion: The modified criterion considering abnormalities in both the anastomosis site and distal run-off improved the diagnostic performance of CTA for HAO in suspected patients with Doppler US abnormalities, particularly by increasing the specificity.

뇌사자 간이식은 말기 간질환 환자에서 최우선치료로 시행되고 있다. 간이식 후 가성동맥류 형성, 동맥 혈전증 및 협착, 정맥의 협착 및 폐색 등 다양한 초기 또는 후기 혈관 합병증이 발생할 수 있으며, 이는 이식 실패를 야기할 수 있다. 이러한 합병증을 빨리 발견하고 적절한 치료를 하는 것이 이식 성공을 달성하고 재이식을 방지하기 위해 중요하다. 이 증례 보고에서는 컴퓨터단층촬영 및 디지털감산 혈관조영술 영상 소견과 협착 부위 전후의 압력차 측정을 통해 뇌사자 간이식 후 발생한 하대정맥 협착 환자에서 즉각적인 인터벤션이 필요한 감별점을 제시하고자 한다.

Purpose: This study aimed to explore young adult donors' experiences of living donor liver transplantation. Methods: A phenomenological research method was used. The participants were two women and six men. Data were collected through individual in-depth interviews from November 25th, 2019 to June 10th, 2020 and analyzed using Colaizzi's phenomenological method. Results: Five theme clusters extracted from the young adult donors' experiences were painful decision of a liver donation, the agony of both mind and body that overpowers youth, the bitter and bare face of reality that a young donor encounters, feeling the power of love that fills up the space of the organ removed, and liver donation becoming priming water for maturity. Conclusion: The results of this study provide a deeper understanding of the lives of young adult donors who have experienced unexpected difficulties as well as self growth from the donation. It is expected that the results can be of use for developing and applying customized nursing interventions for management before and after liver donation among young adult donors.

Three-dimensional computed tomography is an effective tool to estimate the liver volume of living donors for the live liver transplantation. When additional operation is required, magnetic resonance imaging is conducted to determine the safety of the donor. This study compared the accuracy of magnetic resonance imaging and computed tomography in estimating 3D liver volume of 23 male and 7 female donors who underwent both magnetic resonance imaging and computed tomography tests before the transplantation. The analysis was conducted to see whether the liver's estimated total volumes and the left lobe volumes obtained from 3D-magnetic resonance imaging and 3D-computed tomography were identical. Volumes of the right lobe estimated with 3D-magnetic resonance imaging and 3D-computed tomography were compared with the actual volume of the right lobe harvested in the operating room because the volume of the right lobe is an important determinant in the safety of the donor. The total volume of the liver estimated from 3D-magnetic resonance imaging and 3D-computed tomography differed (1238.1904 units and 1402.364 units respectively). The left lobe volume of the liver estimated with 3D-magnetic resonance imaging and 3D-computed tomography also differed (450.530 units and 554.490 units, respectively). The right lobe volume of the liver estimated with 3D-magnetic resonance imaging and 3D-computed tomography were 787.660 units and 847.545 units, respectively, while the actual average right lobe volume of the harvested liver was 678.636 units. 3D-computed tomography has been widely used to estimate the right lobe volume of the donors' liver. However, 3D-magnetic resonance imaging was also very effective in estimating the volume of the liver. Thus, 3D-magnetic resonance imaging is also expected to become an important tool in determining the safety of the donors before transplantation.

Purpose: The anastomosis of hepatic artery to recipient vessel has a major role in a liver transplantation, so its occlusion is the most important cause of failure of liver transplantations. We made the study to reveal the peculiarities in pediatric liver transplantations compared with adult cases. Methods: From January 1999 to September 2005, we performed 99 cases of pediatric liver transplantation. The mean age at operation was 4.17 years of age. The hepatic vein and portal vein are anastomosed by the general surgeons and then the hepatic artery is anastomosed by the plastic surgeons. The Doppler ultrasonography and computed tomography were used for postoperative checkup for hepatic artery patency. Results: There were no immediate complications, but hepatic arterial occlusion was developed in 3 cases (2.8%). In pediatric patients, the anastomosis of hepatic artery is more difficult than adults because of the rapid respiratory and pulse rate, the small vascular diameter, and the large gap of diameter difference between the recipient and the donor vessels. Conclusion: We could confirm that pediatric liver transplantations are relatively safe but long learning curve was needed.
