In order to investigate whether the size of thecaudate lobe of the cirrhotic liver is related to thehepatic functional reserve, the morphometric analysis ofthe caudate lobe was preformed retrospectively using computed tomography in 106 consecutivepatients of whom 67 had compensated (group 1), and 39uncompensated (group 2) liver cirrhosis. In 51 patients,hepatic measurements were repeated in follow-up. Age- and gender-matched controls were studied.The size of the caudate lobe and the ratio of thecaudate to right lobe were correlated with liverfunction. The caudate lobe was larger in the studypatients than in the controls, and larger in group 1than in group 2 (P < 0.01). The caudate to right loberatios were also greater in the study patientsespecially in group 1 (P < 0.01). In follow-up, the regression coefficient for the caudate to rightlobe ratio was positive in group 1 and negative in group2 (P < 0.05). Even though the caudate lobe ofpatients with uncompensated liver cirrhosis was larger than that of the controls, patients withcompensated liver cirrhosis had a larger caudate lobeand higher caudate to right lobe ratio compared to thepatients with uncompensated liver cirrhosis. The caudate lobe may have played an importantrole in maintaining proper liver function in thesepatients. 相似文献

Expansion Conditions for Early Hepatic Progenitor Cells from Embryonal and Neonatal Rat Livers 总被引:6,自引:0,他引:6
Long-term primary cultures were established fromfetal or neonatal livers by using cell suspensionsdepleted of red blood cells and by culturing the cellsin hormonally defined medium containing dimethyl sulfoxide. Two distinct populations of hepaticprogenitor cells were evident in the cultures, based onmorphology, proliferative ability, and liver-specificgene expression. Most colonies consisted of immature hepatic progenitors: small, blastlike cells,weakly expressing alpha-fetoprotein, albumin, and-glutamyltranspeptidase, and showing evidence ofproliferation as measured by bromodeoxyuridineincorporation. At the perimeter of these colonies of immaturecells and forming some colonies by themselves were moremature hepatic progenitor cells: larger cells, withincreased cytoplasmic to nuclear ratios, little proliferation, and strongly expressing albumin,alpha-fetoprotein, and -glutamyltranspeptidase.The latter two proteins were localized to the bilecanalicular membranes of these cells. Glycogen deposits were present in the mature cells from day 14embryos after eight days of culture. Thus, DMSOtreatment of hepatic parenchymal progenitors provides anovel system for studies of liver development. 相似文献

针灸治疗非酒精性脂肪性肝炎的临床观察 总被引:8,自引:0,他引:8
观察针灸疗法治疗非酒精性脂肪性肝炎的临床疗效。【方法】采用随机数字表法将108例患者随机分为两组。电针组(60例)取丰隆穴电针治疗,留针10 min,每天治疗1次,连续治疗6 d后休息1 d,共治疗8周。西药组(48例) 每天给予西药阿托伐他汀片10 mg,1次/d,口服;肝泰乐片0.2 g,3次/d,口服,连续治疗8周。观察两组临床疗效,检测两组治疗前后肝功能指标及血脂水平、肝纤维化指标,同时观察患者的不良反应。【结果】电针组总有效率为91.70%, 西药组为83.30%,电针组疗效优于西药组(P<0.01)。治疗后两组的肝功能指标、血脂水平及肝纤维化指标均有改善 (与治疗前比较,P<0.05或P<0.01),且电针组的改善作用均较西药组好(P<0.05或P<0.01)。西药组部分患者出现恶心、消化不良症状,电针组未发现任何不良反应。【结论】电针丰隆穴能改善非酒精性脂肪性肝炎患者的临床症状,改善肝功能,降低血脂水平和抗肝纤维化作用,对非酒精性脂肪性肝炎有较好的治疗作用。 相似文献

Gastrointestinal complications after laparoscopic Roux-en-Y gastric bypass (LRYGBP) are not uncommon. Leakage of the gastro-jejunal
anastomosis is the main early surgical complication of LRYGBP. Hepatic portal venous gas (HPVG) has been described in association
with a variety of pathologic conditions. HPVG is a potentially life-threatening condition due to its etiology, with a global
survival rate of <25%. We present a case of gastro-jejunal anastomotic leak associated with HPVG after LRYGBP. 相似文献

Liver regeneration after injury with carbontetrachloride (CCl4) followed by partialhepatectomy is a complex model involving toxicological,inflammatory, and necrotic processes. In the presentstudy, the time-course of hepatic regenerative process wasinvestigated in relation to hepatic stimulator substance(HSS) activity, administration of a single dose ofCCl4 and partial (70%) hepatectomy in malerats. To evaluate liver injury events, the levels ofserum aspartic aminotransferase (AST), alanineaminotransferase (ALT), and alkaline phosphatase (ALP)were measured. Hepatic DNA synthesis reached a maximum at 36 hr after hepatectomy in contrast to thereported 24-hr and 32-hr peaks observed in nontreatedhepatectomized rats. On the other hand, HSS activityappeared to peak at 28, 40, and 44 hr after hepatectomy in CCl4-treated rats, and it wasquite a lot lower at 24, 32, 36, 48, and 60 hr. Thehypothesis that HSS promotes liver regeneration but itdoes not initiate it, as other factors have been foundto do, is discussed. 相似文献
