There exists a complex relationship between liver and thyroid hormones. Liver plays an important role in the activation, inactivation, transportation, and metabolism of thyroid hormones. At the same time, thyroid hormones also affect hepatocytes activity and liver metabolism, such as lipid and bilirubin metabolism. Importantly, thyroid hormone levels often change abnormally in patients with liver cirrhosis. Therefore, studying the change of thyroid hormone levels in patients with liver cirrhosis has a certain clinical value for assessing the severity, prognosis, diagnosis and treatment. This paper reviews the research progress on the relationship between liver cirrhosis and thyroid hormone.

Non-alcoholic fatty liver disease (NAFLD) is a metabolic-related disorder induced by multiple factors and mainly characterized by excessive fat buildup in hepatocytes. With the consumption of a Western-style diet and obesity prevalence in recent years, the incidence of NAFLD has gradually increased, becoming an increasingly serious public health problem. Bilirubin is a heme metabolite and a potent antioxidant. Studies have demonstrated that bilirubin levels have an inverse correlation with the incidence rate of NAFLD; however, which form of bilirubin plays the main protective role is still controversial. It is considered that the main protective mechanisms for NAFLD are bilirubin antioxidant properties, insulin resistance reduction, and mitochondrial function. This article summarizes the correlation, protective mechanism, and possible clinical application of NAFLD and bilirubin.

Daily administration of glucocorticoids for 10 days to dogs resulted in a significant increase in the hepatic bile secretion in response to secretory stimulants. The response of hepatic bile in testosterone-treated animals was not changed and the response was increased in DOCA--treated animals. A significant increase of liver weight was induced by the animals receiving glucocorticoids. Other organ weight was not changed; however, a slight reduction of kidney weight was seen in prednisolone, dexamethasone, and DOCA treated animals and also in animals supplemented with cortisone following adrenalectomy. The presence of large areas of ballooning and vesicular changes of liver cells was seen in glucocorticoid treated animals, particularly in cases of dexamethasone and prednisolone. Both vesicular changes of liver cell and its glycogen content were increased by the repeated administration of prednisolone and reduced by the cessation of treatment. Special stain and liver glycogen determination demonstrated the material distending the liver cell was glycogen. These findings indicate that long term administration of glucocorticoids results in an increase of liver weight and hepatic glycogen content as well as increased bile secretion.

High intensity light emitting diodes (LEDs) are being studied as possible light sources for the phototherapy of neonatal jaundice, as they can emit high intensity light of narrow wavelength band in the blue region of the visible light spectrum corresponding to the spectrum of maximal bilirubin absorption. We developed a prototype blue gallium nitride LED phototherapy unit with high intensity, and compared its efficacy to commercially used halogen quartz phototherapy device by measuring both in vitro and in vivo bilirubin photodegradation. The prototype device with two focused arrays, each with 500 blue LEDs, generated greater irradiance than the conventional device tested. The LED device showed a significantly higher efficacy of bilirubin photodegradation than the conventional phototherapy in both in vitro experiment using microhematocrit tubes (44 +/-7% vs. 35 +/-2%) and in vivo experiment using Gunn rats (30 +/-9% vs. 16 +/-8%). We conclude that high intensity blue LED device was much more effective than conventional phototherapy of both in vitro and in vivo bilirubin photodegradation. Further studies will be necessary to prove its clinical efficacy.

9.Hematological Aspects of Congenital Syphilis.
Yonsei Medical Journal 1976;17(2):142-150
Hematologic investigations for 7 years at the Pediatric Department of Yonsei Medical Center of 52 syphilitic infants were reviewed. A moderate degree of anemia with red cell regeneration was observed in 40 infants (76.0%). Marked. thrombocytopenia but without active bleeding was found in 19 infants, and with active bleeding in 3 infants. A wide range of leukocyte counts, relative lymphocytosis and monocytosis were prominant features. The jaundice was mainly due to unconjugated bilirubin in 6 infants, conjugated as well as unconjugated bilirubin in 8 infants. With therapy, the above abnormal hematologic findings showed marked improvement. Early diagnosis is essential. Prevention and congenital syphilis depend on a high level of clinical suspicion, supported by routine and diagnostic use of laboratory and serologic aids, in the asymptomatic or minimally symptomtaic infants.

OBJECTIVETo improve the diagnosis and management of primary biliary cirrhosis (PBC).
METHODSClinical data of 22 cases of PBC were reviewed including the clinical manifestation, laboratory test, and the response to therapy.
RESULTSThere were 20 female patients with an average of 50 years old in total of 22 PBC patients. The major symptoms were pruritus, fatigue, anorexia, and abdominal discomfort. The major signs included jaundice, hepatomegaly, splenmegaly, and ascites. Very high levels of serum alkaline phosphatase (ALP) and serum gamma glutamyl transpeptidase (GGT), hyperbilirubinemia and hypergammaglobulinemia were also detected in most of the patients. The aminotransferase level was only slightly elevated but the AST/ALT ratio was reversed. It took 8 months (ranging from 2 months to 5 years) to confirm the diagnosis after the clinical manifestation onset. Ursodeoxycholic acid could decrease the serum levels of ALP and bilirubin in 80% of the patients (12/15) and improve the symptom of pruritus and fatigue in 72.7% of the patients (11/15).
CONCLUSIONSPBC mainly affects middle-aged women and the main clinical manifestations are hepatosplenomegaly, jaundice, pruritus, and fatigue. Liver function test typically reveal a cholestatic pattern accompanied by hypergammagloblinemia and a positive antimitochondrial antibody (AMA) including M2 subtype (AMA-M2). Ursodeoxycholic acid could improve the abnormal liver function tests and clinical features in PBC patients
