Our data suggests that the decreased serum SOD levels could be implicated in the pathophysiology and progression of autism in Chinese children and can be used as an independent risk indicator of ASD.

Background: it was a meta-analysis on the efficacy of statins in the treatment of atherosclerosis Methods: The PubMed, Medline, Embase, Web of Sciences, and other Chinese and English databases were used to retrieve literature on randomized controlled trials (RCTs) of statins in the treatment of atherosclerosis, published from January 2000 to January 2021. The Cochrane Handbook for Systematic Reviews of Intervention 5.0.2 was used to conduct bias risk assessment, and Review Manager 5.3 software (RevMan) was used for meta-analysis.Results: A total of 12 articles with 1,180 participants were included in the meta-analysis. In the observation group, the plaque area [mean difference (MD) =−1.

Background The current study was conducted to explore the effects of chemerin and homocysteine (Hcy) levels and their associations with the occurrence and development of ischemic cerebrovascular disease (ICVD). Methods There involved a total of 187 patients with ICVD and 190 healthy people for physical examination in Cangzhou Central hospital from January 2020 to April 2021. The participants enrolled were divided into four groups based on the digital subtraction angiography: mild stenosis group (64 cases, stenosis rate 30-49 %), moderate stenosis group (72 cases, stenosis rate 50-69 %), severe stenosis group (51 cases, stenosis rate 70-99 %) and control group (190 cases, in healthy condition). The laboratory indexes of ICVD group and control group were observed and the four groups were further compared. Pearson linear correlation was applied to analyze the link between chemerin and Hcy levels and the degree of cerebral vascular stenosis in ICVD patients, and multivariate logistic regression was used to analyze the influencing factors of ICVD. Results No significant difference was found in general information including age, gender, body mass index (BMI), heart rate, systolic blood pressure, diastolic blood pressure, smoking and drinking between the two groups (P > 0.05). Moreover, there was no significant difference in fasting blood glucose (FBG), total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) levels between the two groups (P > 0.05). However, the levels of triglyceride (TG), low density lipoprotein cholesterol (LDL-C), chemerin and Hcy in ICVD group were significantly higher than those in control group (P < 0.05). When comparing the four groups, there was no significant difference in FBG and TC levels (P > 0.05). The levels of TG, LDL-C, chemerin and Hcy in mild, moderate and severe stenosis groups were higher than those in control group, the above levels in moderate and severe stenosis group were higher than those in mild stenosis group, and severe stenosis group higher than moderate stenosis group (P < 0.05). Chemerin and Hcy levels were positively correlated with the degree of cerebral vascular stenosis in ICVD patients (r = 0.612, 0.519, P < 0.001). ICVD was regarded as the dependent variable, and the abovementioned general data as well as significant laboratory indicators, including TG, LDL-C, chemerin and Hcy, as independent variables. The results of multivariate logistic regression analysis revealed that TG, LDL-C, chemerin and Hcy were independent influencing factors of ICVD. Conclusions Chemerin and Hcy levels exerted a close link to the occurrence and development of ICVD as independent influencing factors.

Objective The study aimed to analyze the relationship between expression levels of chemerin, oxidized low density lipoprotein (ox‐LDL), matrix metalloproteinase 9 (MMP‐9) and pregnancy associated plasma protein A (PAPP‐A) in ischemic cerebrovascular disease (ICVD) patients and the relationship between the mentioned indicators and the degree of neurological impairment. Methods From January 2020 to February 2021, a total of 328 cases of ICVD patients were admitted to our hospital, and 240 cases of healthy people (control group) were prospectively recruited into this study. The 328 patients were divided into 2 ischemic subtypes, with 233 cases as acute cerebral infarction (ACI) and 95 cases as transient ischemic attack (TIA). Laboratory tests were compared among the groups. Spearman rank correlation was used to analyze the correlation between chemerin, ox‐LDL, MMP‐9, PAPP‐A levels and neurological deficit. Unconditional logisitic regression was used to analyze the risk factors for neurological deficits. Results The high density lipoprotein cholesterol (HDL‐C), fasting plasma glucose (FPG), chemerin, ox‐LDL, MMP‐9, and PPAP‐A levels in the ACI group were significantly higher than those in the TIA group and control group ( p < 0.05, respectively), while the levels of the mentioned indicators in the TIA group were significantly higher than those in control group ( p < 0.05, respectively). The levels of the given indicators decreased successively in the severe, moderate, and mild neurological deficits population and control group, with statistical difference. Spearman rank correlation analysis showed that chemerin, ox‐LDL, MMP‐9, and PPAP‐A levels were positively correlated with the degree of neurological deficit in ICVD patients. Unconditional logistic regression analysis showed that chemerin, ox‐LDL, MMP‐9, and PPAP‐A were the independent risk factors for neurological deficit in patients with ICVD. Conclusion LDL‐C, FPG, chemerin, ox‐LDL, MMP‐9, and PPAP‐A were highly expressed in ACI and neurological deficit patients. Chemerin, ox‐LDL, MMP‐9, and PPAP‐A may be the independent risk factors for neurological deficit in patients with ICVD.
