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.
Objective To investigate the effect of chronic altitude hypoxia exposure on serum lipoprotein levels in healthy subjects and patients with pulmonary hypertension, and whether there is a difference in serum lipoprotein levels between patients with pulmonary hypertension at middle and high altitude. Methods The case data of 245 Han patients with COPD complicated with pulmonary hypertension admitted to the Affiliated Hospital of Qinghai University from January 2018 to September 2022 were retrospectively analyzed. According to the altitude of their long-term residence before onset, the patients were divided into two groups, 119 cases in the middle altitude group (1500 m~2500 m). 126 cases were in the high altitude group of 2500 m~4500 m. In addition, the physical examination data of 50 healthy people in the intermediate and high altitude groups were collected as the control group (the age and gender of the healthy people in the same altitude group were similar to those in the COPD-PH group), a total of 4 groups were collected. The general data, pulmonary artery systolic blood pressure (PASP), total cholesterol (TC), triglyceride (TG), high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) of the four groups were compared, and the correlation between pulmonary artery systolic blood pressure (PASP) and related variables was analyzed. ResultsThere were no significant differences in age, gender, smoking and drinking between the healthy control group and COPD-PH group (all P>0.05). There were significant differences in body mass index, PASP, TC, TG, HDL-C, LDL-C, TG/HDL-C, HDL-C/LDL-C between the healthy control group and the COPD-PH group (all P<0.05). In the healthy control group, only BMI was significantly different between the high altitude group and the middle altitude group (P<0.05). In the COPD-PH group, PASP, BMI, TC, HDL-C and TG/HDL-C in the high altitude group were significantly different from those in the moderate altitude group (all P<0.05). There were no significant differences in age, gender, smoking, drinking, TG, LDL-C and HDL-C/LDL-C between the two groups (all P>0.05), when gender, age, altitude, body mass index, PASP, smoking and drinking were included in the multi-factor linear regression equation of lipoprotein (TC, TG, HDL-C and LDL-C), it was found that different elevations (middle and higher elevations) only had statistically different effects on HDL-C (b=-0.046, t=-2.209, P=0.028). Correlation analysis showed that PASP was not correlated with age, altitude, body mass index and blood lipids (TC, TG, HDL-C, LDL-C) in the healthy control group (all P>0.05). However, in the COPD-PH group, PASP was negatively correlated with blood lipid indicators (TC, HDL-C and LDL-C). PASP was positively correlated with altitude (a risk factor for hypoxia). ConclusionsHypoxia environment factors characterized by altitude are closely related to the severity of pulmonary artery pressure in patients with COPD-PH, and higher pulmonary artery systolic pressure is closely related to lower levels of TC, HDL-C and LDL-C.
Objective To assess the effectiveness of xuezhikang for treating diabetic kidney disease. Methods We searched the Cochrane Central Register of Controlled Trials (Issue 3, 2008), MEDLINE (1980 to September 2008), EMbase (1980 to September 2008), CBMdisc (1990 to September 2008), and CNKI (1994 to September 2008). We also hand searched relevant journals and conference proceedings. Randomized controlled trials (RCTs) in which xuezhikang was used to treat diabetic kidney disease were collected. Then we screened the retrieved studies according to predefined inclusion and exclusion criteria, evaluated the quality of included studies, and performed metaanalyses by using The Cochrane Collaboration’s RevMan 4.2 software. Results Nine RCTs were included. Meta-analyses showed that xuezhikang was superior to routine treatment in decreasing 24-hour urinary protein (WMD –0.87, 95%CI –1.34 to –0.41), microalbuminuria (WMD –115.39, 95%CI –127.63 to –103.15), and urinary albumin excretion rate (WMD – 65.46, 95%CI –68.87 to –62.12); but xuezhikang had similar effects in reducing serum creatinine compared with routine treatment (WMD –5.42, 95%CI –11.06 to 0.21). Moreover, xuezhikang was more effective in regulating blood lipids, including TC (WMD –1.71, 95%CI –2.39 to –1.03), TG (WMD –0.96, 95%CI –1.46 to –0.46), LDL-C (WMD –1.01, 95%CI –1.64 to –0.38), and HDL-C (WMD 0.22, 95%CI 0.09 to 0.36). Xuezhikang was not superior to routine treatment in improving fasting blood sugar (WMD -0.01, 95%CI -0.49 to 0.47), but was more effective in improving 2 h-BS (WMD –1.10, 95%CI –1.35 to –0.85) and HbA1c (WMD –0.41, 95%CI –0.56 to –0.27). No significant adverse effects or allergic reactions were reported. Conclusions The evidence currently available shows that xuezhikang may decrease 24-hour urinary protein, microalbuminuria, serum creatinine, regulate blood lipids, and adjust blood glucose. Due to a high risk of selection bias and detection bias in the included studies, the evidence is insufficient to determine the effect of xuezhikang. Further large-scale trials are required to define the role of xuezhikang in the treatment of diabetic kidney disease.
目的 探讨川崎病（Kawasaki disease，KD）患儿血脂代谢与冠状动脉病变之间的关系。 方法 纳入2007年1月-2009年10月住院治疗的82例KD患儿，检测治疗前后血总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL-C）、低密度脂蛋白（LDL-C）、极低密度脂蛋白（VLDL-C）、载脂蛋白A1（ApoA1）及载脂蛋白B100（ApoB100）水平。选取50例健康儿童作为对照。KD患儿在治疗前行超声心动图检查，根据超声心动图显示将KD组再分为冠状动脉病变组（CAL组，n=31）和非冠状动脉病变组（NCAL，n=51）。 结果 治疗前，KD患儿TC、ApoA1、HDLC降低，TG、LDL-C升高，与正常儿童相比有统计学意义（Plt;0.05）。KD患儿CAL组较NCAL组变化更明显，有统计学意义（Plt;0.05）。VLDL-C和ApoB100水平KD患儿与正常儿童比较、NCAL组与CAL组比较变化均不明显（Pgt;0.05）。治疗后与治疗前相比，NCAL组TC、TG、HDL-C、LDL-C、ApoA1恢复正常（Plt;0.05）），而CAL组仅TC、LDL-C、ApoA1恢复正常（Plt;0.05）。 结论 KD患儿存在血脂代谢紊乱，TC、TG、HDL-C、LDL-C、ApoA1与冠状动脉的损害有关，应早期进行干预。
Objective To systematically review the effectiveness and safety of Zhibitai vs. atorvastatin in the treatment of hyperlipidemia. Methods Randomized controlled trials (RCTs) about Zhibitai vs. atorvastatin for hyperlipidemia were electronically retrieved in databases of PubMed, CENTRAL (Issue 7, 2010), CBM,CNKI, VIP and WanFang Data from inception to July, 2012. Two reviewers independently screened literature, extracted data, and assessed methodological quality. Then, meta-analysis was conducted using RevMan 5.2 software. Results A total of 4 RCTs involving 519 cases were included. The results of meta-analysis showed, Zhibitai was superior to atorvastatin in reducing TG levels after 8-week treatment (MD= −0.12, 95%CI −0.23 to −0.01, P=0.03) and increasing HDL-C levels after 8-week treatment (MD= −0.16, 95%CI −0.22 to −0.11, P=0.000 01). But there was no significant difference in decreasing TC levels and LDL-C levels after 4-week treatment and 8-week treatment as well as decreasing TG levels after 4-week treatment between the two groups. No obvious adverse reaction occurred in the two groups, but atorvastatin may impair liver function. Conclusion Current evidence with weak strength shows that, Zhibitai is superior to atorvastatin in reducing TG levels, and increasing HDL-C levels after 8 weeks. However, they are alike in other blood-fat index and safety. Due to the limited quantity and quality of the included studies, more high quality RCTs are needed to verify the above conclusion.
Objective To analyze the prevalence and influencing factors of dyslipidemia among permanent residents in Longquanyi district of Chengdu for prevention and control of dyslipidemia. Methods Permanent residents in Longquanyi district were selected as research objects by convenient sampling method between November 2021 and February 2022. The dyslipidemia rate in the population was analyzed, and the influencing factors of dyslipidemia were analyzed by univariate and multivariate logistic regression. Results A total of 11 408 permanent residents were included. Among them, 3650 people had dyslipidemia, with a prevalence rate of 32.00% (3650/11408). The prevalence rates of high total cholesterol, high triglyceride, high low-density lipoprotein cholesterol, and low high-density lipoprotein cholesterol were 19.30% (2 202/11 408), 13.38% (1 526/11 408), 5.05% (576/11 408) and 0.73% (83/11 408), respectively. Multivariate logistic regression analysis showed that female, age≥30 years old, drinking, overweight / obesity, hypertension, diabetes and hyperuricemia were independent risk factors of dyslipidemia among permanent residents (P<0.05). Conclusions The prevalence of dyslipidemia in Longquanyi district is high, mainly with high total cholesterol and high triglyceride. Gender, age, drinking, body mass index, and the levels of blood pressure, blood glucose and blood uric acid are the factors affecting the incidence of dyslipidemia among permanent residents. Early intervention for high-risk groups with dyslipidemia should be adopted to effectively reduce the risk and burden of dyslipidemia.

Objective To analyze the effects of hyperuricemia (HUA) on the prevalence of dyslipidemia in the elderly. MethodsA total of 5 990 elderly people with complete and important variables from the China Health and Retirement Longitudinal Study (CHARLS) public database in 2015 were extracted. Their blood lipids, related physiological and biochemical indices, and basic demographic information were collected. The effects of HUA on the prevalence of dyslipidemia in the elderly were analyzed using the probit model, and empirical analysis was performed using the propensity score matching method (PSM). Results Among the 5 990 subjects, 13.6% of the elderly had HUA and the prevalence of dyslipidemia was 37.5%. After correcting the endogeneity among variables, the probability of dyslipidemia in elderly patients with HUA increased by 9.5%-11.7% (P<0.01), in which the probability of high triglyceridemia (TG), high total cholesterol (TC), high low-density lipoprotein cholesterol (LDL-C), and low high-density lipoprotein cholesterol (HDL-C) increased by 10.4%-11.5% (P<0.01), 2.7%-3.8% (P<0.01), 1.7%-2.3% (P<0.05), and 4.3%-4.9% (P<0.05), respectively. Conclusion HUA is associated with various types of dyslipidemia, among which its relationship with high TG and low HDL-C is strong. Targeted interventions should be taken for elderly HUA patients, aiming to reduce the rate of dyslipidemia and promote the goal of "healthy ageing" in China.
Objective To evaluate the effects of pseudo-ginseng Tongshu capsule on changes of bloodstream, blood plasma lipid and Fibrin of patients with Brain Infarction.

Before and after the treatment, change of bloodstream, blood plasma lipid and Fibrin were tested. Results A total of 120 patients were included in the treatment group and 86 in the control group. In the 3rd month, the level of total cholesterol (TC) and Fibrinogen was decreased significantly in the patients with Brain Infarction (Plt;0.05). Conclusion The level of blood plasma lipid and Fibrinogen is decreased significantly in the patients with Brain Infarction who accept pseudoginseng Tongshu capsule.
Objective To investigate the correlation between cervical Modic change (MC) and blood lipid and glucose levels. Methods Patients hospitalized with neck and shoulder pain in the Affiliated Hospital of North Sichuan Medical College between January 2015 and January 2021 were selected and divided into MC group and non-MC group according to whether the signal changes of cervical vertebral endplate occurred on MRI. The general data (age, gender, smoking history, drinking history), blood lipid indicators (high-density lipoprotein, low-density lipoprotein, lipoprotein a, total cholesterol, triglyceride) and blood glucose indicators (glycosylated hemoglobin, fasting blood glucose) were compared between the two groups. Multivariate logistic regression analysis was used to explore the correlation between MC and various indicators. Results A total of 160 patients were included, including 48 patients in MC group and 112 patients in non-MC group. The age [(61.46±12.10) vs. (56.22±10.65) years], total cholesterol [(5.06±1.17) vs. (4.44±1.31) mmol/L], triglyceride [(1.61±0.64) vs. (1.38±0.58) mmol/L], glycosylated hemoglobin (6.78%±1.27% vs. 5.79%±0.85%), and fasting blood glucose [(7.84±1.51) vs. (6.93±1.47) mmol/L] of the patients in MC group were significantly higher than those in non-MC group (P<0.05). There was no significant difference in gender, smoking ratio, drinking ratio, high-density lipoprotein, low-density lipoprotein or lipoprotein a between the two groups (P>0.05). Logistic regression analysisshowed that age [odds ratio (OR)=1.064, 95% confidence interval (CI) (1.022, 1.109), P=0.003], total cholesterol [OR=1.788, 95%CI (1.187, 2.694), P=0.005], triglyceride [OR=2.624, 95%CI (1.257, 5.479), P=0.010] and glycosylated hemoglobin [OR=4.942, 95%CI (2.446, 9.987), P<0.001] were risk factors of cervical MC. Conclusions Age, total cholesterol, triglyceride and glycosylated hemoglobin are risk factors of cervical MC. Elderly patients with hyperlipidemia and hyperglycemia should be alert to the occurrence of cervical MC. Controlling the levels of blood lipid and glucose may reduce the risk of cervical MC.
