Amine oxidase copper-containing 1 (AOC1) is a key member of copper amine oxidase family, which is responsible for deamination oxidation of histamine and putrescine. In recent years, AOC1 has been reported to be associated with various cancers, with its expression levels significantly elevated in certain cancer cells, suggesting its potential role in cancer progression. However, its function in lipid metabolism still remains unclear. Through genetic analysis, we have discovered a potential relationship between AOC1 and lipid metabolism. To further investigate, we generated Aoc1−/− mice and characterized their metabolic phenotypes on both chow diet and high-fat diet (HFD) feeding conditions. On HFD feeding conditions, Aoc1−/− mice exhibited significantly higher fat mass and impaired glucose sensitivity, and lipid accumulation in white adipose tissue and liver was also increased. This study uncovers the potential role of AOC1 in lipid metabolism and its implications in metabolic disorders such as obesity and type 2 diabetes, providing new targets and research directions for treating metabolic diseases.
Objective To assess the improvement of different resistance training regimens on blood lipid metabolism and insulin resistance in patients with type 2 diabetes mellitus (T2DM). Methods PubMed, ProQuest, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang, and VIP databases were searched to collect randomized controlled trials of resistance training intervention to improve blood lipids and insulin resistance in patients with T2DM. The search time range was from the establishment of the databases to May 2023. Two reviewers assessed the risk of bias of the included studies using the Physiotherapy Evidence Database scale, and performed a network meta-analysis of the extracted data using Stata 16.0 software. Results In the end, 24 articles were included, and a total of 983 participants were enrolled. The result of network meta-analysis showed that high-frequency and moderate-intensity resistance exercise significantly improved the levels of insulin resistance [standardized mean difference=−1.71, 95% confidence interval (CI) (−2.75, −0.67)], triglycerides [weighted mean difference (WMD)=−0.27 mmol/L, 95%CI (−0.51, −0.04) mmol/L], and total cholesterol [WMD=−0.16 mmol/L, 95%CI (−0.20, −0.12) mmol/L], but had no significant effect on improving the level of high-density lipoprotein [WMD=0.05 mmol/L, 95%CI (−0.02, 0.11) mmol/L] or low-density lipoprotein [WMD=−0.20 mmol/L, 95%CI (−0.42, 0.03) mmol/L]. The results of cumulative probability ranking showed that high-frequency and moderate-intensity resistance exercise was the best in improving insulin resistance, triglycerides, high-density lipoprotein and low-density lipoprotein levels. Conclusion Based on current evidence, high-frequency and moderate-intensity resistance exercise may be the best resistance exercise regimen to improve insulin resistance and lipid metabolism in patients with T2DM.
ObjectiveTo investigate the prevalence of chronic obstructive pulmonary disease (COPD) with lipid metabolism disorders patients in Chengdu. MethodsWe randomly selected four communities from urban and rural areas in Chengdu between February and December, 2010, with multistage cluster random sampling method; 1 931 residents aged from 40 to 70 received special questionnaire from the BOLD Study, lung examination, blood biochemical examination, and physical examination. ResultsThe prevalence of COPD was 60.26% (91/151) with dyslipidemia; while non-COPD was 68.17% (972/1 428), and the difference was significant (P<0.05), in which the most obvious difference is triglycerides (TG). The prevalence of COPD was 6.62% (10/151) with underweight; while non-COPD was 4.97% (71/1 428), and the difference was significant (P<0.001). The prevalence of COPD was 21.19% (32/151) with abdominal obesity; while non-COPD was 30.81% (440/1 428), and the difference was significant (P<0.05). ConclusionThe prevalence of COPD with lipid metabolism disorders is lower than which with non-COPD in Chengdu. It provides an evidence for the nutrition support therapy in the treatment of COPD.

Endocrinology is closely related to lipid metabolism. Lipotoxicity affects the abnormal function of various endocrine organs, and leads to diabetes, fatty liver, metabolic syndrome and other endocrine and metabolic diseases. It is an important strategy to prevent the lipid toxicity. Endocrine disorders can also cause dyslipidemia. Studies have found that thyroid and gonadal glands play an important role in lipid metabolism. Their molecular mechanisms are gradually revealed and will be a new therapeutic target for dyslipidemia. Lipid metabolism disorders play an important role in the development of endocrine and metabolic diseases.
Objective To study the effects of glucose and lipid metabolism on gallstone formation. Methods Twenty five patients with gallstones and 25 normal volunteer controls were studied from January to April in 1998. The patients were well matched the control with sex and age (1∶1). In the study, Body Mass Index (BMI) and Waist-to-Hip circumference ratio (W/H) were measured. Blood glucose, glucosylated hemoglobin (HbA1C), insulin, C peptide and all parameters of lipids were detected at fasting state. The glucose,insulin, C peptide were detected again at 2-hour after taking 75g glucose orally.Results The result showed there was no difference on BMI and W/H between the patients and controls. HbA1C、mean fasting and 2hour glucose concentration were not in significantly different between the two groups (Pgt;0.05, Pgt;0.2, Pgt;0.1 respectively). There were 10 patients with abnormal glucose metabolism (7 with NIDDM, 3 with IGT), but only 4 controls were abnoumal (one with NIDDM, three with IGT). The difference was significant (Plt;0.05). Furthermore, the mean fasting and 2hour insulin concentration of gallstone group was higher than that of the control (Plt;0.02, Plt;0.05). And the gallstone group had a higher fasting C peptide concentration than control (Plt;0.05). There was no statistical difference on the parameters of plasma lipid between the tow groups. Conclusion The study suggests that diabetes mellious and hyperinsulinemia acted as an important role on gallstone formation.
To investigate prospectively the short-term effect of different fat emulsions on plasma lipids and lipoproteins and to clarify the underlying mechanisms. Fifty six surgical patients were randomized to received intravenously either a 10%. Intralipid, a 20% Intralipid or no fat emulsions for 5 days postoperatively as part of a standard parenteral nutrition regimen. Serum lipids and lipoproteins were measured prior to and after the 5-day infusion period. Results: Intravenous administration of 10% Intralipid caused a marked increase of total cholesterol (Tcho), free cholesterol (Fcho), Low-density lipoprotein cholesterol (LDL-ch), phospholipid and lipoprotein X (LPX). Quantification of LPX revealed that its increase was proportionate to that of phospholipid and Tcho. Conclusion: Exogenous phospholipids when using fat emulsions with a high phospholipid/triglyceride (PL/TG) ratio play an impressive role in the formation of LPX and consequently are capable of inducing hypercholesterolemia after only a few days. Therefore, 20% Intralipid should be preferred to the corresponding 10% Intralipid for its low PL/TG ratio.
ObjectiveTo systematically review the intervention effects of high-intensity interval training (HIIT) on weight loss and blood lipid metabolism in overweight/obese populations. MethodsThe computer conducted searches in the PubMed, Embase, Cochrane Library, Web of Science, CNKI, and WanFang Data database to collect randomized controlled trials (RCTs) related to HIIT and weight loss, fat reduction, and blood lipid metabolism in overweight/obese populations. The search was conducted from the inception of the databases to March 31, 2023. Two researchers independently conducted literature screening and data extraction. After evaluating the risk of bias of the included studies, a meta-analysis was performed using RevMan 5.4 software. ResultsA total of 19 RCTs, involving 595 overweight/obese participants, were included. The meta-analysis results showed that compared wtih the control group, HIIT interventions effectively reduced body weight (MD=−2.63, 95%CI −4.04 to −1.23, P<0.05), BMI (MD=−1.21, 95%CI −1.95 to −0.48, P<0.05), Fat% (MD=−1.66, 95%CI −2.28 to −1.04, P<0.05), TG (MD=−0.13, 95%CI −0.25 to −0.01, P=0.04), HDL (MD=0.14, 95%CI 0.05 to 0.23, P<0.05), and LDL (MD=−0.26, 95%CI −0.39 to −0.13, P<0.05) levels but did not improve TC (MD=−0.15, 95%CI −0.36 to 0.06, P=0.15) levels. ConclusionHIIT intervention can effectively improve body weight, BMI, Fat%, TG, HDL, and LDL levels in overweight/obese populations, particularly showing a more pronounced improvement in lipid profiles among overweight/obese adolescents, but it does not reduce TC levels. This study demonstrates that HIIT may be an effective strategy to assist in weight loss and prevent cardiovascular diseases in overweight/obese populations, with potential for broader application.
