4Expanding etiology of progressive familial intrahepatic cholestasis显示文摘BACKGROUND Progressive familial intrahepatic cholestasis(PFIC)refers to a disparate group of autosomal recessive disorders that are linked by the inability to appropriately form and excrete bile from hepatocytes,resulting in a hepatocellular form of cholestasis.While the diagnosis of such disorders had historically been based on pattern recognition of unremitting cholestasis without other identified molecular or anatomic cause,recent scientific advancements have uncovered multiple specific responsible proteins.The variety of identified defects has resulted in an ever-broadening phenotypic spectrum,ranging from traditional benign recurrent jaundice to progressive cholestasis and end-stage liver disease.AIM To review current data on defects in bile acid homeostasis,explore the expanding knowledge base of genetic based diseases in this field,and report disease characteristics and management.METHODS We conducted a systemic review according to PRISMA guidelines.We performed a Medline/PubMed search in February-March 2019 for relevant articles relating to the understanding,diagnosis,and management of bile acid homeostasis with a focus on the family of diseases collectively known as PFIC.English only articles were accessed in full.The manual search included references of retrieved articles.We extracted data on disease characteristics,associations with other diseases,and treatment.Data was summarized and presented in text,figure,and table format.RESULTS Genetic-based liver disease resulting in the inability to properly form and secrete bile constitute an important cause of morbidity and mortality in children and increasingly in adults.A growing number of PFIC have been described based on an expanded understanding of biliary transport mechanism defects and the development of a common phenotype.CONCLUSION We present a summary of current advances made in a number of areas relevant to both the classically described FIC1(ATP8B1),BSEP(ABCB11),and MDR3(ABCB4)transporter deficiencies,as well as more recently described gene mutations--TJP2(TJP2),FXR(NR1H4),MYO5B(MYO5B),and others which expand the etiology and understanding of PFIC-related cholestatic diseases and bile transport.Sarah AF Henkel Judy H Squires Mary Ayers Armando Ganoza Patrick Mckiernan James E Squires 2019World Journal of Hepatology2019,11,5:13
5Spontaneous rupture of hepatic hemangiomas:A review of the literature显示文摘Hepatic hemangiomas are congenital vascular malformations,considered the most common benign mesenchymal hepatic tumors,composed of masses of blood vessels that are atypical or irregular in arrangement and size. Hepatic hemangiomas can be divided into two major groups:capillary hemangiomas and cavernous hemangiomas These tumors most frequently affect females (80%) and adults in their fourth and fifth decades of life. Most cases are asymptomatic although a few patients may present with a wide variety of clinical symptoms,with spontaneous or traumatic rupture being the most severe complication. In cases of spontaneous rupture,clinical manifestations consist of sudden abdominal pain,and anemia secondary to ahaemoperitoneum. Disseminated intravascular coagulopathy can also occur. Haemodynamic instability and signs of hypovolemic shock appear in about one third of cases. As the size of the hemangioma increases,so does the chance of rupture. Imaging studies used in the diagnosis of hepatic hemangiomas include ultrasonography,dynamic contrast-enchanced computed tomography scanning,magnetic resonance imaging,hepatic arteriography,digital subtraction angiography,and nuclear medicine studies. In most cases hepatic hemangiomas are asymptomatic and should be followed up by means of periodic radiological examination. Sur gery should be restricted to specific situations. Absolute indications for surgery are spontaneous or trau m atic rupture with hemoperitoneum,intratumoral blee ding and consumptive coagulopathy (Kassabach-Merrit syndrome). In a patient presenting with acute abdo minal pain due to unknown abdominal disease,sponta neous rupture of a hepatic tumor such as a hemangio ma should be considered as a rare differential diagnosis.Marcelo AF Ribeiro Francine Papaiordanou Juliana M Gonalves Eleazar Chaib 2010World Journal of Hepatology2010,2,12:12
6Characterization of monocarboxylate transporter activity in hepatocellular carcinoma显示文摘AIM: To assess the immunoexpression of hypoxiarelated markers in samples from cirrhosis and primary and metastatic hepatocellular carcinoma(HCC).METHODS: From a total of 5836 autopsies performed at the Pathology Department- University of Sao Paulo School of Medicine Hospital- from 2003 to 2009, 188 presented primary liver tumors. Immunohistochemical reactivity for monocarboxylate transporters(MCTs)-1, 2 and 4, CD147 and glucose transporter-1(GLUT1)was assessed in necropsies from 80 cases of HCC. Data were stored and analyzed using the IBM SPSS statistical software(version 19, IBM Company, Armonk, NY). All comparisons were examined for statistical significance using Pearson's χ2 test and Fisher's exact test(when n < 5). The threshold for significant P values was established as P < 0.05.RESULTS: Plasma membrane expression of MCT4 and overall expression of GLUT1 showed progressively higher expression from non-neoplastic to primary HCC and to metastases. In contrast, overall expression of MCT2 was progressively decreased from non-neoplastic to primary HCC and to metastases. MCT1(overall and plasma membrane expression), MCT2 and CD147 plasma membrane expression were associated with absence of cirrhosis, while plasma membrane expression of CD147 was also associated with absence of HBV infection. MCT2 overall expression was associated with lower liver weight, absence of metastasis and absence of abdominal dissemination. Additionally, MCT4 plasma membrane positivity was strongly associated with Ki-67 expression. CONCLUSION: MCT4 and GLUT1 appear to play a role in HCC progression, while MCT2 is lost during progression and associated with better prognosis.Venncio AF Alves Céline Pinheiro Filipa Morais-Santos Aloisio Felipe-Silva Adhemar Longatto-Filho Fátima Baltazar 2014World Journal of Gastroenterology2014,20,33:11
7Cytomegalovirus frequency in neonatal intrahepatic cholestasis determined by serology, histology, immunohistochemistry and PCR显示文摘AIM: To determine cytomegalovirus (CMV) frequency in neonatal intrahepatic cholestasis by serology, histological revision (searching for cytomegalic cells), immunohistochemistry, and polymerase chain reaction (PCR), and to verify the relationships among these methods.METHODS: The study comprised 101 non-consecutive infants submitted for hepatic biopsy between March 1982 and December 2005. Serological results were obtained from the patient's f iles and the other methods were performed on paraffin-embedded liver samples from hepatic biopsies. The following statistical measures were calculated: frequency, sensibility, specif ic positive predictive value, negative predictive value, and accuracy.RESULTS: The frequencies of positive results were as follows: serology, 7/64 (11%); histological revision, 0/84; immunohistochemistry, 1/44 (2%), and PCR, 6/77 (8%). Only one patient had positive immunohistochemical fi ndings and a positive PCR. The following statistical measures were calculated between PCR and serology: sensitivity, 33.3%; specificity, 88.89%; positive predictive value, 28.57%; negative predictive value, 90.91%; and accuracy, 82.35%. CONCLUSION: The frequency of positive CMV varied among the tests. Serology presented the highest positive frequency. When compared to PCR, the sensitivity and positive predictive value of serology were low.Maria Angela Bellomo-Brandao Paula D Andrade Sandra CB Costa Cecilia AF Escanhoela Jose Vassallo Gilda Porta Adriana MA De Tommaso Gabriel Hessel 2009World Journal of Gastroenterology2009,15,27:8

9Percutaneous radiofrequency ablation for early hepatocellular carcinoma: Risk factors for survival显示文摘AIM: To evaluate outcomes of radiofrequency ablation(RFA) therapy for early hepatocellular carcinoma(HCC) and identify survival- and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography(CT) or magnetic resonance imaging(MRI)(single nodule of ≤ 5 cm, or multi-(up to 3) nodules of ≤ 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Cancer do Estado de S o Paulo, Brazil were enrolled in the study. RFA of the liver tumors(with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response(absence of enhancing tissue at the tumor site) or incomplete response(enhancing tissue remaining at the tumor site). Overall survival and diseasefree survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients(age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo(range, 1-33). The study population showed predominance of male sex(76%), less severe liver disease(Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor(65%). The maximum tumor diameters ranged from 10 to 50 mm(median, 26 mm). The initial(immediately post-procedure) rate of RFAinduced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule(vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema(resolved with intervention) and intestinal perforation(led to death). The 1- and 2-year overall survival rates were 82% and 71%, respectively. Sex, tumor size, initial response, and recurrence status influenced survival, but did not reach the threshold of statistical significance. Child-Pugh class and the model for end-stage liver disease score were identified as predictors of survival by simple Cox regression, but only Child-Pugh class showed a statistically significant association to survival in multiple Cox regression analysis(HR = 15; 95%CI: 3-76 mo; P = 0.001). The 1-and 2-year cumulative disease-free survival rates were 65% and 36%, respectively. CONCLUSION: RFA is an effective therapy for local tumor control of early HCC, and patients with preserved liver function are the best candidates.Luciana Kikuchi Marcos Menezes Aline L Chagas Claudia M Tani Regiane SSM Alencar Marcio A Diniz Venncio AF Alves Luiz Augusto Carneiro D’Albuquerque Flair José Carrilho 2014World Journal of Gastroenterology2014,20,6:5
10用真比重分离法研究一种飞灰残炭的生成途径和再燃特性显示文摘根据煤在足够高温度下,停留时间越长,分子结构的晶格化程度越高,因而反应活性越低,同时真比重也越大的原理,采用重液将一种链条锅炉飞灰中的残炭颗粒富集并按不同真比重分开。各比重组颗粒表面积测定结果符合不同燃尽度焦炭比表面积变化规律;小流化床燃烧实验证明随真比重增大,残炭颗粒本征反应活性降低。说明真比重分离法对于判断飞灰残炭颗粒的形成途径和再燃特性很有效。实验结果表明,链条炉飞灰残炭并不主要由原煤中的细小颗粒形成,由中等和大颗粒原煤形成的飞灰残炭占相当比例;在真比重最大的残炭组中,细小颗粒所拥有的总碳量最大。估计它们是由大颗粒或大块原煤经过炉内高温区、停留时间长,燃烧后期碎裂形成的。房靖华 Saro.,AF 1998燃料化学学报1998,26,5:4

12复杂性区域疼痛综合征和纤维肌痛病人的身体变化及感官敏感度显示文摘复杂性区域性疼痛综合征(CRPS)和纤维肌痛都是病因不明的慢性疼痛性疾病。除了诊断标准中的症状外,病人还可主诉视力以及其他感觉或身体机能的变化。目前尚不清楚这些症状是否与年龄增长、持续的慢性疼痛或慢性疼痛的常见共患病(如抑郁或焦虑)有关。本文作者进行了一项在线调查,纳入CRPS(n=390)、纤维肌痛(n=425)以及同时患有CRPS和纤维肌痛(n=88)的病人,评估他们的躯体症状、身体变化以及感官敏感度的频率和类型的改变,并与其他慢性疼痛病人对照组(n=331)和无疼痛对照组(n=441)相比较。该调查评估了躯体症状(病人健康问卷,Patient health questionnaire-15,PHQ-15)、身体变化、疼痛/不适/困扰的诱发因素和疼痛的加剧因素。将年龄、性别、抑郁症量表(patient health questionnaire-9,PHQ-9)、广泛性焦虑障碍量表(generalized anxiety disorder,GAD-7)、疼痛持续时间、每天疼痛时间和与疼痛相关的诊断数量作为协变量分析其协方差。在控制协变量后,CRPS和/或纤维肌痛病人的躯体症状、身体变化包括运动及生理反应的变化、疼痛、不适、困扰的诱发因素和疼痛加剧因素均多于其他慢性疼痛及无疼痛对照组的病人。纤维肌痛与视力、听力、泌尿/肠道功能及饮食的改变相关。CRPS与头发、皮肤和指甲的改变相关,且与感染和愈合相关。同时患有CRPS和纤维肌痛的病人表现出这两种疾病的特征,除此之外,基本无其他症状。本研究的发现提示:尽管其具体的机制可能不同,但CRPS和纤维肌痛有共同的病理生理学基础。Ten Brink AF Peters L Kompouli PI 商澜镨(译) 李水清(校) 2021中国疼痛医学杂志2021,27,3:3

20Giant squamous cell carcinoma of the gallbladder: A case report显示文摘BACKGROUND Gallbladder cancer is the most common malignant tumor of the biliary tract. The majority of cases are adenocarcinoma. Squamous cell carcinoma is the histological type present in 12% of all neoplasias accounting for approximately 12% of gallbladder neoplasms. It can occur in its pure form reaching 1%-3% of the tumors. Many patients are at an advanced stage when diagnosed and have bad therapeutic efficacy. CASE SUMMARY A 45-year-old male patient presented with left flank pain for 1 year and irradiated to the mesogastric region. He denied fever, vomiting, and any other intestinal changes. He reported a weight loss of 10 kg in a period of 7 mo. He denied alcoholism, smoking, drug use, or prior illness. Computed tomography of the abdomen showed in the gallbladder fossa a voluminous mesogastric heterogeneous collection that had a thick and irregular capsule with liquid and gaseous contents. A predominantly hypoattenuating rounded material with partially calcified margins measuring about 2.0 cm related to gallstone was also emphasized. No lymphadenomegalies or free fluid was observed in the abdominal cavity. Patient underwent laparotomy where a huge tumor was observed affecting the transverse colon and gallbladder. This mass was resected en bloc removing gallbladder and transverse colon together with corresponding mesocolon and regional lymphadenectomy. There were no complications in the postoperative period. Although oncological treatment was performed, the patient died 6 mo after surgery. CONCLUSION Squamous cell carcinoma represents a rare disease. Patients often present with large, bulky tumors with involvement of adjacent organs. In spite of progress in surgical techniques and adjuvant chemotherapy, the prognosis remains poor.Marcelo AF Ribeiro Junior Murillo de Lima Favaro Stephanie Santin Cintia Magalhaes Silva Ana Paula Marconi Iamarino 2019World Journal of Clinical Cases2019,7,18:2
