Lipids changes in liver cancer 总被引:9,自引:1,他引:8
Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus (HBV) and hepatitis C virus (HCV). HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer. 相似文献

Colostrum, the mammary secretion during first 2–4 days of lactation, provides all the essential components of nutrition and
passive immunity required by the newborn. Pregnancy induced hypertension (PIH), glucose intolerance and anaemia are common
medical complications observed during pregnancy in Indian women and their effects were studied on the composition of colostrum
collected within 24 hours of delivery from lactating women included in the study. PIH during pregnancy significantly decreased
colostrum IgA and total proteins, but showed a significant increase in K+ levels, where as women with glucose intolerance showed a significant decrease in total lipids and lactose and an increase
in Na+ levels in colostrum compared to normal controls. The group with anaemia also showed a significant decrease in colostrum IgA
and total protein levels when compared with the control group. Awareness about the changes that occur in the composition of
colostrum during complicated pregnancies can be an important and useful tool for preventive and protective paediatrics. 相似文献

The present study has investigated the levels of lipids, lipoprotein cholesterol (HDL and LDL cholesterol), thiobarbituric
acid reactive substances (TBARS) and vitamin E in plasma and erythrocyte membranes of twenty two clinically diagnosed adult
rheumatoid arthritis patients and an equal number of age matched healthy subjects. The levels of lipids and lipoprotein cholesterol
were markedly reduced in patients with rheumatoid arthritis as compared to healthy subjects. The altered lipid pattern may
be related to decreased lipoprotein cholesterol, fatty acids and impairment in antioxidant defence mechanism. 相似文献

Lipid abnormalities remain to be a major cause of early mortality in patients with chronic renal failure (CRF). In present
study, 114 (one hundred fourteen) CRF patients without any additional cause of dyslipidemia were divided into groups on the
basis of etiologies of CRF. Blood samples from each group were analyzed for total cholesterol, triglyceride and HDL cholesterol
along with blood urea nitrogen and serum creatinine. 25 healthy individuals without any obvious disease were taken as control.
Patients from all the groups showed a marked hypertriglyceridemia of 232 (SD±77) mg/dl (P<0.001) as compared to control. Levels
of HDL cholesterol were found to be significantly low 20 (±11) mg/dl (p<0.001) in all the groups. LDL cholesterol showed an
increase 104 (±30) mg/dl as compared to control group which is not statistically significant. Present study reveals that,
CRF patients show an uniform dyslipidemia irrespective of etiologies leading to CRF. This dyslipidemia is also independent
of serum creatinine levels. Although, these lipid abnormalities may not solely cause mortality in CRF patients, they may act
as modulators in accelerating atherogenesis which in turn cause early mortality in CRF patients. 相似文献

The aim of the study was to evaluate the influence of rotavirus (RV) and soyabean trypsin inhibitor (TI) on lipid composition
and uptake of glucose and glycine in rotavirus (RV) infected malnourished (PEM) infant mice. Malnutrition was achieved in
animals by doubling the litter size. Cholesterol (Ch) and phospholipd (PL) contents, uptake levels of glucose and glycine
were determined in jejunum and ileum portion of small intestine. Increase in Ch/PL ratios was observed in PEM+RV group. The
levels became comparable in PEM+RV+TI as compared to PEM. Uptake levels of glucose and glycine increased in PEM animals. With
rotavirus (PEM+RV+TI group), the levels decreased which became comparable to PEM. Changes in uptake and lipid composition
with rotavirus and trypsin inhibitor may be responsible for altering membrane fluidity and organization during rotavirus diarrhea.
The results establish the importance of trypsin inhibitor during oral infection with rotavirus. 相似文献

Glyco-oxidation is considered as a source of permanent, cumulative, oxidative damage to long lived proteins in ageing and
in diabetes. Although RBC depends solely on glucose for energy purpose, hyperglycemic state glycosylates hemoglobin, creates
oxidative stress and puts the cellular components at risk. In view of this, RBC membrane composition was analyzed in diabetic
patients. The results were compared with healthy age and sex matched control groups. When RBC membrane components such as
protein, sialic acid, phospholipids and cholesterol were determined in insulin dependent diabetes mellitus, a significant
rise in phospholipids and cholesterol and significant fall in sialic acid and protein content was noted. RBC membrane composition
showed pronounced alterations in insulin dependent diabetes mellitus. These changes were accompanied by higher levels of lipid
peroxidation products like Malondialdehyde. 相似文献

Serum lipid profile has now become almost a routine test. It is usually done in fasting state due to certain limitations in
non-fasting serum sample. In the recent past efforts have been made to simplify blood sampling by replacing fasting lipid
profile with non-fasting lipid profile. However, fasting specimen is preferred if cardiovascular risk assessment is based
on total cholesterol, LDL cholesterol or non-HDL cholesterol. A lot has yet to be done in this area. Till then we have to
believe in fasting lipid profile for assessment and management of cardiovascular disease. 相似文献

Reference intervals for pubertal characteristics are influenced by genetic, geographic, dietary and socioeconomic factors. Therefore, the aim of this study was to establish age-specific reference intervals of glucose and lipid levels among local school children. This was cross-sectional study, conducted among Saudi school children. Fasting blood samples were collected from 2149 children, 1138 (53%) boys and 1011 (47%) girls, aged 6 to 18 years old. Samples were analyzed on the Architect c8000 Chemistry System (Abbott Diagnostics, USA) for glucose, cholesterol, triglycerides, HDL and LDL. Reference intervals were established by nonparametric methods between the 2.5th and 97.5th percentiles. Significant differences were observed between boys and girls for cholesterol and triglycerides levels in all age groups (P < 0.02). Only at age 6–7 years and at adolescents, HDL and LDL levels were found to be significant (P < 0.001). No significant differences were seen in glucose levels except at age 12 to 13 years. Saudi children have comparable serum cholesterol levels than their Western counterparts. This may reflect changing dietary habits and increasing affluence in Saudi Arabia. Increased lipid screening is anticipated, and these reference intervals will aid in the early assessment of cardiovascular and diabetes risk in Saudi pediatric populations. 相似文献
