    新烟碱(NEO)是目前世界上增长最快,使用最广泛的杀虫剂类。越来越多的证据表明,环境中的长期NEO残留物对非目标土壤动物具有毒性作用。然而,很少有研究对近地天体对土壤动物的影响进行调查,只有少数人专注于全球系统评价或荟萃分析,以量化近地天体对土壤动物的影响。这里,我们对来自113个现场和实验室研究的2940个观察结果进行了荟萃分析,这些研究调查了NEO(浓度为0.001-78,600.000mg/kg)对五个指标中不同土壤动物的影响(即,生存,增长,行为,繁殖,和生化生物标志物)。此外,我们量化了近地天体对不同物种土壤动物的影响。结果表明,近地天体抑制了生存,增长率,行为,和土壤动物的繁殖,并改变生化生物标志物。NEO残基使个体的存活率和寿命均降低了100%。青少年生存的平均值,茧号,卵孵化率降低了97%,100%,84%,分别。个体和茧重量都减少了82%,而NEO残留的增长率下降了88%。我们的荟萃分析证实,近地天体对土壤动物造成重大负面影响。
    Neonicotinoids (NEOs) are currently the fastest-growing and most widely used insecticide class worldwide. Increasing evidence suggests that long-term NEO residues in the environment have toxic effects on non-target soil animals. However, few studies have conducted surveys on the effects of NEOs on soil animals, and only few have focused on global systematic reviews or meta-analysis to quantify the effects of NEOs on soil animals. Here, we present a meta-analysis of 2940 observations from 113 field and laboratory studies that investigated the effects of NEOs (at concentrations of 0.001-78,600.000 mg/kg) on different soil animals across five indicators (i.e., survival, growth, behavior, reproduction, and biochemical biomarkers). Furthermore, we quantify the effects of NEOs on different species of soil animals. Results show that NEOs inhibit the survival, growth rate, behavior, and reproduction of soil animals, and alter biochemical biomarkers. Both the survival rate and longevity of individuals decreased by 100 % with NEO residues. The mean values of juvenile survival, cocoon number, and egg hatchability were reduced by 97 %, 100 %, and 84 %, respectively. Both individual and cocoon weights were reduced by 82 %, while the growth rate decreased by 88 % with NEO residues. Our meta-analysis confirms that NEOs pose significant negative impacts on soil animals.

    胰岛素样生长因子-1(IGF-1)具有多种神经营养作用,包括神经发生,髓鞘再生和突触发生,是神经元可塑性的有效调节剂。尽管多项研究已经调查了IGF-1在抑郁症相关疾病中的作用,很少有研究关注首次明确诊断为抑郁症的患者,这些患者以前从未使用过抗抑郁药。因此,这项研究调查了首发和未服用药物的抑郁症患者,以补充目前关于抑郁症中IGF-1水平的证据。
    本研究由两部分组成。在第一部分,60例首次发作和首次用药的抑郁症患者和60例年龄相匹配的对照组,性别,和BMI从芜湖市第四医院门诊部招募,和社区。采用病例对照法比较两组间血清IGF-1水平的差异。在第二部分,通过数据库筛选13项病例对照研究进行荟萃分析,以验证结果的可靠性。
    病例对照研究的结果表明,与健康对照组相比,首次发作和未用药抑郁症患者的血清IGF-1水平显着升高(p<0.05)。尽管诊断为MDD的男性和女性之间没有显着差异,抑郁症患者血清IGF-1水平与年龄无显著相关性,IGF-1水平与抑郁症严重程度无显著相关性。荟萃分析证实了这些发现,并证明MDD患者的IGF-1水平明显高于健康对照组。
    首次发作和未服用药物的抑郁症患者的IGF-1水平更高,但在IGF-1与抑郁症相关的研究中排除混杂因素必须严格考虑,需要更多的研究来充分了解IGF-1在抑郁症中的关键作用。

    UNASSIGNED: Insulin-like growth factor-1 (IGF-1) has a variety of neurotrophic effects, including neurogenesis, remyelination and synaptogenesis, and is an effective regulator of neuronal plasticity. Although multiple studies have investigated IGF-1 in depression-related disorders, few studies have focused on patients with a first episode of clearly diagnosed depression who had never used antidepressants before. Therefore, this study investigated first-episode and drug-naïve patients with depression to supplement the current evidence around IGF-1 levels in depressive disorders.
    UNASSIGNED: This study consisted of two parts. In the first part, 60 patients with first-episode and drug-naïve depression and 60 controls matched for age, sex, and BMI were recruited from the outpatient department of the Fourth Hospital of Wuhu City, and the community. The case-control method was used to compare differences in serum IGF-1 levels between the two groups. In the second part, 13 case-control studies were screened through the database for meta-analysis to verify the reliability of the results.
    UNASSIGNED: Results of the case-control study demonstrated that serum IGF-1 levels are significantly higher in patients with first-episode and drug-naïve depression compared to healthy controls (p<0.05), although there was no significant difference between men and women with diagnosed MDD, there was no significant correlation between serum IGF-1 level and age in patients with depression and no significant correlation between IGF-1 level and the severity of depression. The meta-analysis corroborates these findings and demonstrated that IGF-1 levels are significantly higher in MDD patients than in healthy controls.
    UNASSIGNED: Patients with first-episode and drug-naïve depression have higher IGF-1 levels, but the exclusion of confounding factors in studies of IGF-1 as it relates to depressive disorders must be taken into consideration strictly, and additional research is needed to fully understand the critical role of IGF-1 in depression.

    该研究旨在通过全面评估病例对照研究,系统地确定在胃癌中观察到的肠道微生物群的变化。
    PubMed的系统文献检索,Embase,科克伦图书馆,和WebofScience进行了病例对照研究,这些研究比较了患有和不患有胃癌的个体的微生物群。采用纽卡斯尔-渥太华质量评价量表(NOS)对纳入研究的质量进行评价。荟萃分析利用随机效应模型,进行亚组和敏感性分析以评估研究异质性.所有数据分析均使用Stata17.0中的“metan”软件包进行,并使用具有95%置信区间(CI)的对数比值比(logOR)描述结果。
    共有33项研究涉及4,829名参与者有资格进行分析,其中29项研究提供了α多样性的变化,18项研究报告了β多样性。Meta分析显示,只有Shannon指数对α-多样性有统计学意义[-5.078(-9.470,-0.686)]。在门水平上没有观察到显著差异,虽然11种细菌在属水平上被鉴定出显著变化,例如,乳杆菌[5.474,(0.949,9.999)]和链球菌[5.095,(0.293,9.897)]的增加,而卟啉单胞菌和Rothia的减少则相同[-8.602,(-11.396,-5.808)]。敏感性分析表明,9个细菌属的变化是稳健的。对国家的亚组分析显示,患有胃癌的韩国人中,螺杆菌和链球菌的丰度越来越高,而来自葡萄牙的胃癌患者的奈瑟氏球菌减少。关于样本来源,该研究观察到胃癌患者胃粘膜中乳杆菌和拟杆菌的增加,以及螺杆菌和链球菌。然而,与非胃癌组相比,拟杆菌的相对丰度降低,在粪便样本中显示。
    这项研究确定了胃癌患者中9种细菌属的强烈变化,这是特定于国家/样本来源的。需要进行大规模的研究来探索这些变化背后的机制。

    UNASSIGNED: The study aims to systematically identify the alterations in gut microbiota that observed in gastric cancer through comprehensive assessment of case-control studies.
    UNASSIGNED: The systematic literature search of PubMed, Embase, Cochrane Library, and Web of Science was conducted to identify case-control studies that compared the microbiomes of individuals with and without gastric cancer. Quality of included studies was evaluated with the Newcastle-Ottawa Quality Assessment Scale (NOS). Meta-analyses utilized a random-effects model, and subgroup and sensitivity analyses were performed to assess study heterogeneity. All data analyses were performed using the \"metan\" package in Stata 17.0, and the results were described using log odds ratios (log ORs) with 95% confidence intervals (CIs).
    UNASSIGNED: A total of 33 studies involving 4,829 participants were eligible for analysis with 29 studies provided changes in α diversity and 18 studies reported β diversity. Meta-analysis showed that only the Shannon index demonstrated statistical significance for α-diversity [-5.078 (-9.470, -0.686)]. No significant differences were observed at the phylum level, while 11 bacteria at genus-level were identified significant changed, e.g., increasing in Lactobacillus [5.474, (0.949, 9.999)] and Streptococcus [5.095, (0.293, 9.897)] and decreasing in Porphyromonas and Rothia with the same [-8.602, (-11.396, -5.808)]. Sensitivity analysis indicated that the changes of 9 bacterial genus were robust. Subgroup analyses on countries revealed an increasing abundance of Helicobacter and Streptococcus in Koreans with gastric cancer, whereas those with gastric cancer from Portugal had a reduced Neisseria. Regarding the sample sources, the study observed an increase in Lactobacillus and Bacteroides in the gastric mucosa of people with gastric cancer, alongside Helicobacter and Streptococcus. However, the relative abundance of Bacteroides decreased compared to the non-gastric cancer group, which was indicated in fecal samples.
    UNASSIGNED: This study identified robust changes of 9 bacterial genus in people with gastric cancer, which were country-/sample source-specific. Large-scale studies are needed to explore the mechanisms underlying these changes.

    背景:C-X-C基序趋化因子配体(CXCL8),白细胞介素8是一种典型的CXC家族趋化因子,带有谷氨酸-亮氨酸-精氨酸(ELR)基序,在人类一系列癌症的发生和发展中起关键作用。许多先前的研究集中在探索CXCL8基因多态性与癌症风险之间的关系。然而,其中许多报告的统计能力有限,在许多情况下产生模棱两可或冲突的结果。
    方法:因此,PubMed,万方,使用关键字\'IL-8\'或\'白介素-8\'或\'CXCL8\'搜索Scopus和WebofScience数据库,查找直到2023年7月20日发表的文章,“多态性”和“癌症”或“肿瘤”。利用赔率比(ORs)和95%置信区间(CIs)检查相关性。用TaqMan测定评估CXCL8+781多态性基因型。
    结果:为了更好地理解这些多态性与疾病风险之间的关联,进行了约29篇相关出版物。CXCL8-353A/T多态性与总体癌症风险增加相关[A与T,优势比(OR)=1.255,95%置信区间(CI)(1.079-1.459),P异质性=0.449,P=0.003]。CXCL8+781T/C等位基因与高加索人的癌症风险相似[TT与TC+CC,OR=1.320,95CI(1.046-1.666),异质性=0.375,P=0.019]。此外,与CC基因型相比,携带CXCL8+781TT+TC基因型的口腔癌患者血清CXCL8水平显着增加(P<0.01),与基因型匹配的正常对照相比,也显示出相似的趋势(P<0.01)。最后,几个限制,如纳入研究中可能存在发表偏倚或异质性,应引起重视.
    结论:目前的研究表明,CXCL8-353和+781多态性可能与更高的癌症风险有关,这可能会影响癌症的预防,诊断,或通过CXCL8的不同表达进行治疗。同时,+781多态性可能进一步提供作为生物标志物的价值,有助于口腔癌的早期识别和预后评估.
    BACKGROUND: C-X-C motif chemokine ligand (CXCL8), also known as interleukin-8, is a prototypical CXC family chemokine bearing a glutamic acid-leucine-arginine (ELR) motif that plays key roles in the onset and progression of a range of cancers in humans. Many prior studies have focused on exploring the relationship between CXCL8 gene polymorphisms and the risk of cancer. However, the statistical power of many of these reports was limited, yielding ambiguous or conflicting results in many cases.
    METHODS: Accordingly, the PubMed, Wanfang, Scopus and Web of Science databases were searched for articles published until July 20, 2023 using the keywords \'IL-8\' or \'interleukin-8\' or \'CXCL8\', \'polymorphism\' and \'cancer\' or \'tumor\'. Odds ratios (ORs) and 95% confidence intervals (CIs) were utilized to examine the association. The CXCL8 +781 polymorphism genotypes were assessed with a TaqMan assay.
    RESULTS: About 29 related publications was conducted in an effort to better understand the association between these polymorphisms and disease risk. The CXCL8 -353A/T polymorphism was associated with an increased overall cancer risk [A vs. T, odds ratio (OR) = 1.255, 95% confidence interval (CI) (1.079-1.459), Pheterogeneity = 0.449, P = 0.003]. The CXCL8 +781 T/C allele was similarly associated with a higher risk of cancer among Caucasians [TT vs. TC + CC, OR = 1.320, 95%CI (1.046-1.666), Pheterogeneity = 0.375, P = 0.019]. Furthermore, oral cancer patients carrying the CXCL8 +781 TT + TC genotypes exhibited pronounced increases in serum levels of CXCL8 as compared to the CC genotype (P < 0.01), and also shown similar trend as compared to genotype-matched normal controls (P < 0.01). Finally, several limitations, such as the potential for publication bias or heterogeneity among the included studies should be paid attention.
    CONCLUSIONS: Current study suggested that the CXCL8 -353 and +781 polymorphisms may be associated with a greater risk of cancer, which might impact cancer prevention, diagnosis, or treatment through the different expression of CXCL8. At the same time, the +781 polymorphism may further offer value as a biomarker that can aid in the early identification and prognostic evaluation of oral cancer.

    小儿脑瘫(CP)是一种非进行性脑损伤综合征,其特征是中枢运动功能障碍和大脑协调能力不足。CP的病因复杂,常伴有多种并发症,如智力障碍和语言障碍,使临床治疗困难。尽管有药物干预措施,康复计划,和痉挛缓解手术作为CP的治疗选择,他们的有效性仍然受到限制。电针(EA)刺激已经证明了运动功能的巨大改善,但它的全面,对小儿CP的客观治疗效果尚待阐明.
    我们介绍一例5岁的中国女性儿童,在4岁时被诊断为CP。患者表现出严重的运动障碍,语言,社会,和认知功能。我们进行了为期3个月的EA康复,在0个月时获得患者的静息状态功能磁共振成像(rs-fMRI),治疗开始后3个月和5个月,然后表征每个阶段的大脑功能连接模式进行比较。
    经过12个月的随访,患者的语言和社交症状有显著改善.功能连接模式的变化证实了这种治疗效果,并在不同的恢复阶段显示出特定的益处:从语言功能开始,然后调节社会参与和其他发育行为。
    这是一个开创性的报告,证明电针刺激对CP患者功能性脑连通性的纵向影响,提示EA是与小儿CP相关的发育障碍(尤其是语言和社交功能障碍)的有效干预措施。
    UNASSIGNED: Pediatric cerebral palsy (CP) is a non-progressive brain injury syndrome characterized by central motor dysfunction and insufficient brain coordination ability. The etiology of CP is complex and often accompanied by diverse complications such as intellectual disability and language disorders, making clinical treatment difficult. Despite the availability of pharmacological interventions, rehabilitation programs, and spasticity relief surgery as treatment options for CP, their effectiveness is still constrained. Electroacupuncture (EA) stimulation has demonstrated great improvements in motor function, but its comprehensive, objective therapeutic effects on pediatric CP remain to be clarified.
    UNASSIGNED: We present a case of a 5-year-old Chinese female child who was diagnosed with CP at the age of 4. The patient exhibited severe impairments in motor, language, social, and cognitive functions. We performed a 3-month period of EA rehabilitation, obtaining resting state functional magnetic resonance imaging (rs-fMRI) of the patient at 0 month, 3 months and 5 months since treatment started, then characterized brain functional connectivity patterns in each phase for comparison.
    UNASSIGNED: After a 12-month follow-up, notable advancements were observed in the patient\'s language and social symptoms. Changes of functional connectivity patterns confirmed this therapeutic effect and showed specific benefits for different recovery phase: starting from language functions then modulating social participation and other developmental behaviors.
    UNASSIGNED: This is a pioneering report demonstrating the longitudinal effect of EA stimulation on functional brain connectivity in CP patients, suggesting EA an effective intervention for developmental disabilities (especially language and social dysfunctions) associated with pediatric CP.

    骨关节炎(OA)起因于遗传和环境因素的复杂相互作用。大量研究探讨了生长分化因子5(GDF-5)+104T>C多态性与OA风险的关系,但调查结果尚无定论。我们对704例OA病例和418例健康对照进行了病例对照研究。此外,我们通过彻底搜索9月1日之前发表的相关研究的文献进行了荟萃分析,2023年。组合比值比和95%置信区间用于评估相关性的强度。共有47项独立病例对照研究,包括17602例OA病例和30947例对照,进行了分析。其中,31项研究(11,176例,16,724个对照)专注于膝盖OA,8项研究(3,973例,8,055个对照)检查了髋关节OA,和6项研究(2244例,5965个对照)调查了手部OA。总的来说,我们的发现表明,GDF-5104T>C多态性在全球范围内对OA的发展具有保护作用。按种族划分的亚组分析表明,这种遗传变异为高加索人提供了对OA的保护,亚洲人,和非洲人口。基于OA类型的进一步亚组分析显示,与这种变异相关的膝关节和手OA的风险降低,但不适用于髋关节OA。我们的综合数据表明,GDF-5+104T>C多态性提供了对OA发展的保护,以及膝盖和手OA。然而,该多态性与髋关节OA的发生无相关性。
    Osteoarthritis (OA) arises from a intricate interplay of genetic and environmental factors. Numerous studies have explored the link between the growth differentiation factor 5 (GDF-5) +104T>C polymorphism and OA risk, but the findings have been inconclusive. We carried out a case-control study with 704 OA cases and 418 healthy controls. Furthermore, we conducted a meta-analysis by thoroughly searching the literature for relevant studies published until 1 September, 2023. The combined odds ratio and 95% confidence intervals were used to assess the correlation\'s strength. A total of 47 independent case-control studies, including 17,602 OA cases and 30,947 controls, were analyzed. Of these, 31 studies (11,176 cases, 16,724 controls) focused on knee OA, 8 studies (3,973 cases, 8,055 controls) examined hip OA, and 6 studies (2244 cases, 5965 controls) investigated hand OA. Overall, our findings suggest that the GDF-5 + 104T>C polymorphism has a protectibe role in development of OA in global scale. Subgroup analyses by ethnicity indicated that this genetic variation provides protection against OA in Caucasian, Asian, and African populations. Further subgroup analysis based on the type of OA showed a decreased risk of knee and hand OA associated with this variation, but not for hip OA. Our combined data indicates that the GDF-5 + 104T>C polymorphism offers protection against the development of OA in general, as well as knee and hand OA. Nevertheless, there was no correlation found between this polymorphism and the development of hip OA.

    个体患者数据(IPD)荟萃分析建立在传统(汇总数据)荟萃分析的基础上,通过从个体研究中收集IPD而不是使用汇总汇总数据。尽管传统和IPD荟萃分析都产生了汇总效果估计,IPD元分析允许将数据分析作为单个数据集执行。这允许曝光的标准化,结果,和跨个体研究的分析方法。IPD荟萃分析还允许利用队列研究中通常使用的统计方法,比如多变量回归,生存分析,倾向得分匹配,统一的亚组和敏感性分析,更好地管理缺失的数据,并纳入未公布的数据。然而,它们更耗时,昂贵的,并受到参与偏见的影响。当违反比例风险假设时,另一个问题涉及元分析挑战。在这些情况下,报告时间至事件估计的替代方法,如限制平均生存时间应使用。本统计入门课程总结了两种情况下的关键概念,并提供了相关示例。
    Individual patient data (IPD) meta-analyses build upon traditional (aggregate data) meta-analyses by collecting IPD from the individual studies rather than using aggregated summary data. Although both traditional and IPD meta-analyses produce a summary effect estimate, IPD meta-analyses allow for the analysis of data to be performed as a single dataset. This allows for standardization of exposure, outcomes, and analytic methods across individual studies. IPD meta-analyses also allow the utilization of statistical methods typically used in cohort studies, such as multivariable regression, survival analysis, propensity score matching, uniform subgroup and sensitivity analyses, better management of missing data, and incorporation of unpublished data. However, they are more time-intensive, costly, and subject to participation bias. A separate issue relates to the meta-analytic challenges when the proportional hazards assumption is violated. In these instances, alternative methods of reporting time-to-event estimates, such as restricted mean survival time should be used. This statistical primer summarizes key concepts in both scenarios and provides pertinent examples.

    背景:炎症性肠病(IBD)关键疗法的随机对照试验(RCT)通常在完整发表之前的重要时间内作为摘要提供。经常被用来制定战略和临床处方决策。我们比较了仅出版前摘要报告及其各自的全文手稿的一致性。
    方法:对相同的RCT结果的全文手稿及其各自的出版前摘要报告,同时纳入分析的时间点.RCT在2010年至2023年之间发表了全文手稿,以治疗IBD。
    结果:我们发现了77对全文手稿及其出版前的仅摘要报告。在报告所述计划结果时存在重大不匹配(65/77匹配,p<0.001)和主要结果报告在其结果部分(67/77,p<0.001);试验注册(34/65,p<0.001);随机参与者人数(49/77,p=0.18);达到研究结束的参与者(21/71,p<0.001)和主要结果数据(40/73,p<0.001)。作者的结论一致(75/77,p=0.157)。作者没有对上述任何项目的缺失或不一致提供明确或暗示的理由。
    结论:仅摘要报告与以后的全文出版物相比,主要信息报告有限,数据差异显着。这些与患者的进一步招募或单词计数限制无关,并且从未得到解释。由于摘要经常在指南中使用,审查和利益相关者对处方的决策,强烈建议谨慎使用。需要进一步的工作来提高仅抽象作品的最低报告标准,并确保与最终发表的论文保持一致。
    BACKGROUND: Randomised controlled trials (RCTs) of key therapies in inflammatory bowel disease (IBD) are often presented and available as abstracts for significant periods of time prior to full publication, often being employed to make strategic and clinical prescribing decisions. We compared the concordance of prepublication abstract-only reports and their respective full-text manuscripts.
    METHODS: Pairs of full-text manuscripts and their respective prepublication abstract-only reports for the same RCT outcomes, at the same time point of analysis were included. The RCTs were on treatments for IBD with full-text manuscripts published between 2010 and 2023.
    RESULTS: We found 77 pairs of full-text manuscripts and their prepublication abstract-only reports. There were significant mismatches in the reporting of stated planned outcomes (65/77 matched, p<0.001) and primary outcomes reported in their results sections (67/77, p<0.001); trial registrations (34/65, p<0.001); the number of randomised participants (49/77, p=0.18); participants reaching end of study (21/71, p<0.001) and primary outcome data (40/73, p<0.001). Authors conclusions matched (75/77, p=0.157). Authors did not provide explicit or implied justifications for the absence or non-concordance for any of the above items.
    CONCLUSIONS: Abstract-only reports have consistent issues with both limited reporting of key information and significant differences in data when compared with their later full-text publications. These are not related to further recruitment of patients or word count limitations and are never explained. As abstracts are often used in guidelines, reviews and stakeholder decision-making on prescribing, caution in their use is strongly suggested. Further work is needed to enhance minimum reporting standards in abstract-only works and ensure consistency with final published papers.

    结论:我们的集体数据表明rs642961和rs2235371多态性与总体人群中NSCL/P风险之间存在显著关联。rs2235375多态性可能会影响基于种族背景的NSCL/P的易感性。同时,rs2013162多态性在高加索人提供保护作用,混合种群,巴西人口。
    BACKGROUND: Non-syndromic cleft lip with or without cleft palate (NSCL/P) is a prevalent craniofacial birth defect on a global scale. A number of candidate genes have been identified as having an impact on NSCL/P. However, the association between interferon regulatory factor 6 (IRF6) polymorphisms and NSCL/P has yielded inconsistent results, prompting the need for a meta-analysis to obtain more accurate estimates.
    METHODS: We conducted a thorough screening of all relevant articles published up until November 15, 2023, in online bibliographic databases. The statistical analysis of the collected data was performed using the Comprehensive Meta-Analysis (Version 4.0) software.
    RESULTS: A total of 79 case-control studies, comprising 14,003 cases and 19,905 controls, were included in our analysis. The combined data indicated that the IRF6 rs642961 and rs2235371 polymorphisms were associated with an increased risk of NSCL/P in the overall population. However, no significant association was found between the rs2013162 and rs2235375 polymorphisms and the risk of NSCL/P in the overall population. Furthermore, subgroup analyses revealed significant correlations between the IRF6 rs642961, rs2235371, and rs2235375 polymorphisms and the risk of NSCL/P based on ethnic background and country of origin. Nevertheless, the rs2013162 polymorphism plays a protective role in Caucasians and mixed populations.
    CONCLUSIONS: Our collective data indicates a significant association between the rs642961 and rs2235371 polymorphisms and the risk of NSCL/P in the overall population. The rs2235375 polymorphism could influence the susceptibility to NSCL/P based on ethnic background. Meanwhile, the rs2013162 polymorphism provides protective effects in Caucasian, mixed populations, and the Brazilian population.

    方法:我们搜索了三个数据库(PubMed,Embase,和WebofScience)有关高脂血症的文献,脂质水平,和认知障碍,并使用纽卡斯尔-渥太华量表评估已鉴定文献的质量。使用RevMan5.4进行荟萃分析,并使用随机效应模型(优势比[OR]和95%置信区间[CI])评估血脂异常和认知障碍之间的关联。
    结果:在最初确定的2247篇论文中,我们最终纳入了18项研究,共涉及758,074例患者.荟萃分析结果显示,高脂血症患者的认知障碍风险比血脂水平正常的患者高1.23倍(OR=1.23,95%CI:1.04-1.47,p=0.02)。进一步的亚组分析显示,总胆固醇(TC)水平升高会使认知障碍的风险增加1.59倍(OR=1.59,95%CI:1.27-2.01,p<0.0001),并且在老年或男性患者中更为显着。此外,甘油三酯水平升高与认知障碍呈负相关,而低密度脂蛋白胆固醇水平升高与认知障碍风险无关.
    结论:血脂异常与认知障碍密切相关,TC水平升高是认知障碍的危险因素。此外,TC水平升高对认知功能的损害效应在老年和男性人群中更为明显.
    BACKGROUND: This study explored the specific relationship between different lipid indicators and cognitive impairment and aimed to provide a reference for implementing targeted lipid regulation measures to prevent and alleviate cognitive impairment.
    METHODS: We searched three databases (PubMed, Embase, and Web of Science) for literature related to hyperlipidaemia, lipid levels, and cognitive impairment, and used the Newcastle-Ottawa Scale to evaluate the quality of the identified literature. A meta-analysis was performed using RevMan 5.4, and the combined effect size ratio using a random-effects model (odds ratio [OR] and 95% confidence interval [CI]) was used to evaluate the association between dyslipidaemia and cognitive impairment.
    RESULTS: Among initially identified 2247 papers, we ultimately included 18 studies involving a total of 758,074 patients. The results of the meta-analysis revealed that patients with hyperlipidaemia had a 1.23-fold higher risk of cognitive impairment than those with normal lipid levels (OR = 1.23, 95% CI: 1.04-1.47, p = 0.02). Further subgroup analysis showed that elevated total cholesterol (TC) levels increased the risk of cognitive impairment by 1.59-fold (OR = 1.59, 95% CI: 1.27-2.01, p < 0.0001) and were more significant in older or male patients. Moreover, elevated triglyceride levels were inversely correlated with cognitive disorders, whereas elevated low-density lipoprotein cholesterol levels were unrelated to cognitive impairment risk.
    CONCLUSIONS: Dyslipidaemia was strongly associated with cognitive impairment, and elevated TC levels were a risk factor for cognitive impairment. Furthermore, the damaging effects of elevated TC levels on cognition were more pronounced in older and male populations.
