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.
The hallmark lesions of age-related macular degeneration (AMD) are drusen and basal linear deposit which are lipid substances deposited in Bruch membrane or the compartment on the Bruch membrane. There is a prevailing hypothesis that lipid and its oxidized derivant deposited in retina may have important roles in the pathogenesis of AMD. Lipid oxidation products are toxic, may affect the adjacent cells, induce inflammation, and trigger neovascularization.7-ketocholestoral (7KCh), a naturally occurring oxidized form of cholesterol, had been found to be toxic to retinal cells and able to induce chronic inflammation, which may play a critical role in the development of AMD. However the precise mechanism remains to be elucidated. Thus we will make a brief review of 7KCh and its association with AMD.
In recent years, the incidence of hyperlipidemia acute pancreatitis (HLAP) has been increasing year by year, but its pathogenesis has not been completely clear. There are many clinical treatment methods for HLAP, such as lipid-lowering drugs, low molecular weight heparin, insulin, and plasma exchange. Actively reducing serum triglyceride is the core of treatment. Plasma exchange can quickly and effectively reduce the level of triglyceride, and its application in the treatment of HLAP is gradually increasing. This article reviews the recent advances in the pathogenesis, clinical characteristics, diagnosis, and treatment of HLAP, focusing on the mechanism, indications, timing, and disadvantages of plasma exchange therapy for HLAP.
【Abstract】ObjectiveTo detect the levels of homocysteine (Hcy) and anti-phospholipid antibodies (APLA) in the hematoplasma of the patients with deep venous thrombosis (DVT), discuss the reason of DVT recurrence and search for the predictors of it. MethodsSixty cases with DVT in our department from January 2001 to April 2003 were collected, which were divided equally into two groups as primary and recurrent, and first degree relative of the 30 DVT recurrent patients were also collected. The author established a control group using 30 cases of outpatient clinic without varicose veins of lower extremity or insufficient venae profundae. Hcy was detected with fluorescence polarization immunoassay (FPIA) and APLA 〔anticardiolipin antibody, ACLA (IgG, IgM); lupus antibody (LA)〕were detected with enzyme linked immunosorbent assay (ELISA). Odds ratios (OR) were also calculated to assess the relative risk of each study group. ResultsThe values of Hcy and ACLA （IgG， IgM） in the primary group and recurrent group were both significantly higher than those of control group and first degree relative group of DVT recurrent patients (Plt;0.01). The values of Hcy in first degree relative group of DVT recurrent patients was were also much higher than that of control group (Plt;0.05). The 90% quantity of Hcy in control group was 13.1 μmol/L and if taking it as the normal value, the number of cases exceeded this value in primary group, recurrent group and first degree relative group of DVT recurrent patients were 14, 21 and 13 and the OR of them were 2.31, 2.20 and 1.90, respectively. The positive rates of LA were not statistically significant in each group. Conclusion The values of Hcy and APLA both rise in the hematoplasma of DVT patients. There are close relationship between the levels of Hcy and APLA and DVT. The recurrence of DVT is related to high level of Hcy and Hcy is possibly a predictor of DVT.
Objective To probe into disorder of plasma lipids and apolipoproteins in patients with gallstone,and their position and function in formation of gallstone. MethodsConcentration of plasma lipids and apolipoproteins in 94 healthy subjects and 161 patients with gallstones was investigated. ResultsThe gallstone group had a higher serum mean concentration of TG,Apo CⅡ,Apo CⅢ, and had a lower serum mean concentration of TC，HDLc，HDL2c，HDL3c and LDLc as compared with the control group (P＜0.01 or P＜0.05). Conclusion Higher serum mean concentration of TG，Apo CⅡ，Apo CⅢ, and lower serum mean concentration of TC, HDLc, HDL2c, HDL3c and LDLc, are characteristic of lipids metabolism and important cause of formation of gallstone.

1993年10月至1994年2月对中—长链脂肪乳剂(实验组，n=40)和长链脂肪乳剂(对照组，n=30)在静脉营养中的疗效进行了对比观察。从术后第1天起，除从周围静脉输注必需液体外，每日静滴中—长链或长链脂肪乳剂500～1000ml，连续3～5天。监测项目包括血压、脉搏、呼吸、体温、血红蛋白、白细胞、肝肾功能、血甘油三酯及血胆固醇。结果显示：两组均无全笛反应；在输脂肪乳剂后6小时，两组血甘油三酯含量均明显升高，并于12小时时达峰值，16小时时已明显下降，但对照组明显高于实验组(Plt;0.05)，24小时时仍维持较高水平。由此表明，中—长链肪乳剂较易从血清中清除；中链甘油三酯能快速进入线粒体被氧化供能，不依赖内毒碱的转运，能经肝脏生成更多的酮体，极少再脂化为脂肪贮存起来。
Objective To study the clinical protective effect of hemoperfusion combined with hemofiltration on inflammatory reaction of hyperlipidemia severe acute pancreatitis (HLSAP). Methods Thirty-seven patients with HLSAP treated between January 2012 and December 2014 were selected and divided into three groups based on different treatments. Thirteen patients were allocated into hemoperfusion combined with continuous veno-venous hemofiltration group (HP+CVVH group) and treated with hemoperfusion combined with hemofiltration; 11 patients were allocated into continuous veno-venous hemofiltration group (CVVH group) and treated with hemofiltration; and all the other patients were allocated into control group and treated with conventional treatment. The levels of blood triglyceride, C-reactive protein, tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8) and acute physiology and chronic health evaluation (APACHE)Ⅱ score of the patients after treatment were observed. The hospital stay, organ dysfunction rate and mortality of the patients were measured. Results Compared with the control group, the levels of blood triglyceride, C-reactive protein, TNF-α, IL-6, IL-8 and APACHE Ⅱ score of the patients in the HP+CVVH group and CVVH group were both significantly reduced 72 hours after therapy (P<0.05). However, the levels of blood triglyceride, C-reactive protein, TNF-α, IL-6, IL-8 and APACHE Ⅱ score of the patients in the HP+CVVH group were significantly lower than those in the CVVH group at the same time point (P<0.05). The hospital stay of the patients in the HP+CVVH group and CVVH group was significantly shorter than that in the control group (P<0.05). Compared with the CVVH group, the hospital stay of patients in the HP+CVVH group was significantly shorter (P<0.05). There was no statistical difference in organ dysfunction rate and mortality among the three groups (P>0.05). Conclusion Hemoperfusion combined with hemofiltration is an effective method for HLSAP by cleaning the inflammatory mediators availably and inhibiting the excessive inflammatory reaction.
Objective To investigate the long-term dynamic changes of liver function and glucose-lipid metabolism in human immunodeficiency virus (HIV)-infected patients with metabolic dysfunction-associated fatty liver disease (MAFLD) after antiretroviral therapy (ART). Methods HIV-infected patients who visited Public Health Clinical Center of Chengdu between October 1st, 2012 and June 30th, 2013 were recruited and divided into two groups according to whether they had MAFLD or not. All of them were treated with the first-line regimen of tenofovir + lamivudine + efavirenz for 156 weeks, and the anthropometric indices, liver function, and levels of glucose, lipids and uric acid were measured at baseline and at each follow-up time point. In addition, the long-term dynamic characteristics of liver function and glucose and lipid metabolism parameters of the two groups were compared during the 156 weeks of ART treatment. Results A total of 61 male HIV-infected patients were enrolled. The prevalence of MAFLD in them was 31.1% (19/61) at baseline and increased by 4.9 percentage points per year after ART. Before the start of follow-up (week 0), the levels of alanine aminotransferase (ALT) [(46.23±27.09) vs. (28.00±17.43) U/L, P=0.002] and γ-glutamyl transpeptidase (GGT) [(41.46±9.89) vs. (24.02±10.72) U/L, P<0.001] were higher in the MAFLD group than those in the non-MAFLD group, while the between-group differences in the levels of aspartate aminotransferase (AST) [(33.33±15.61) vs. (28.98±12.43) U/L, P=0.248] and alkaline phosphatase [(85.30±21.27) vs. (83.41±24.47) U/L, P=0.773] were not statistically significant. During the 156-week follow-up period, the 4 items of liver function gradually increased in the MAFLD group, especially from week 120 onwards, 3 of which (ALT, AST and GGT) were significantly higher than those in the non-MAFLD group (P<0.05). In addition, the levels of fasting blood glucose, triglyceride, total cholesterol, and low-density lipoprotein were also significantly higher in the MAFLD group than those in the non-MAFLD group at some time points during the 156-week follow-up period (P<0.05). Conclusions Compared with HIV-infected patients without MAFLD, HIV-infected patients with MAFLD are more likely to develop impaired liver function and disorders of glucose and lipid metabolism during long-term tenofovir + lamivudine + efavirenz regimen ART treatment. Therefore, close clinical monitoring of liver function and glucose and lipid metabolism related parameters is required for such patients.
