Objective To investigate the correlation between non-high density lipoprotein cholesterol(non-HDL-C),homocysteine(Hey)levels and cognitive impairment,prognosis in patients with thalamic infarction.Methods Eighty thalamic infarction patients admitted to Puyang People's Hospital from March 2017 to March 2021 were selected as the research sub-jects.According to Montreal cognitive assessment(MoCA)score,the patients were divided into cognitive impairment group(MoCA score＜26,n=35)and cognitive normal group(MoCA score 26-30,n=45).Another 50 healthy individuals who un-derwent physical examinations during the same period were selected as the control group.The serum cholesterol(TC),high-density lipoprotein cholesterol(HDL-C),Hcy levels of all subjects were detected by fully automated biochemical analyzer,and the non-HDL-C levels were calculated.The correlations between non-HDL-C,Hey levels and MoCA scores were analyzed by Pearson correlation analysis,and the diagnostic efficacy of non-HDL-C,Hcy levels for cognitive impairment of patients with tha-lamic infarction was analyzed by receiver operating characteristic curve.According to the modified Rankin scale(mRS)score,the patients with thalamic infarction were divided into good prognosis group(mRS score ≤2,n=50)and poor prognosis group(mRS score 3-6,n=50).The independent risk factors for poor prognosis of patients with thalamic infarction was analyzed by multivariate logistic regression.Results The serum levels of non-HDL-C and Hcy of patients in the cognitive impairment group were significantly higher than those in the cognitive normal group and control group(P＜0.05);there was no significant difference in the serum non-HDL-C,Hcy levels of subjects between the control group and the cognitive normal group(P＞0.05).The non-HDL-C,Hcy levels were negatively correlated with MoCA scores in thalamic infarction patients(P＜0.05).The area under the curve(AUC)of Hcy level in the diagnosis of cognitive impairment was 0.709,the sensitivity was 0.724 and the specificity was 0.630;the AUC of non-HDL-C level in the diagnosis of cognitive impairment was 0.738,the sensitivity was 0.701 and the specificity was 0.870;the AUC of Hey combined with non-HDL-C in the diagnosis of cognitive impairment was 0.769,the sensitivity was 0.758 and the specificity was 0.889.The diagnostic efficacy of Hey combined with non-HDL-C for cognitive impairment was superior to that of non-HDL-C or Hey alone.Atrial fibrillation,elevated levels of non-HDL-C,Hcy and NIHSS score were independent risk factors for poor prognosis of patients with thalamic infarction(P＜0.05).Conclusion The levels of non-HDL-C and Hey are positively correlated with cognitive impairment in patients with thalamic infarction.The levels of non-HDL-C and Hey can be used to diagnose cognitive impairmnent in patients with thalamic infarction,and the combined detection has a better diagnostic effect.Atrial fibrillation,elevated levels of non-HDL-C,Hcy and NIHSS score are independent risk factors for poor prognosis in patients with thalamic infarction.

Background::The conversion of adenosine (A) to inosine (I) through deamination is the prevailing form of RNA editing, impacting numerous nuclear and cytoplasmic transcripts across various eukaryotic species. Millions of high-confidence RNA editing sites have been identified and integrated into various RNA databases, providing a convenient platform for the rapid identification of key drivers of cancer and potential therapeutic targets. However, the available database for integration of RNA editing in hematopoietic cells and hematopoietic malignancies is still lacking.Methods::We downloaded RNA sequencing (RNA-seq) data of 29 leukemia patients and 19 healthy donors from National Center for Biotechnology Information (NCBI) Gene Expression Omnibus (GEO) database, and RNA-seq data of 12 mouse hematopoietic cell populations obtained from our previous research were also used. We performed sequence alignment, identified RNA editing sites, and obtained characteristic editing sites related to normal hematopoietic development and abnormal editing sites associated with hematologic diseases.Results::We established a new database, "REDH", represents RNA editome in hematopoietic differentiation and malignancy. REDH is a curated database of associations between RNA editome and hematopoiesis. REDH integrates 30,796 editing sites from 12 murine adult hematopoietic cell populations and systematically characterizes more than 400,000 edited events in malignant hematopoietic samples from 48 cohorts (human). Through the Differentiation, Disease, Enrichment, and knowledge modules, each A-to-I editing site is systematically integrated, including its distribution throughout the genome, its clinical information (human sample), and functional editing sites under physiological and pathological conditions. Furthermore, REDH compares the similarities and differences of editing sites between different hematologic malignancies and healthy control.Conclusions::REDH is accessible at http://www.redhdatabase.com/. This user-friendly database would aid in understanding the mechanisms of RNA editing in hematopoietic differentiation and malignancies. It provides a set of data related to the maintenance of hematopoietic homeostasis and identifying potential therapeutic targets in malignancies.

Objective:To analyze and compare the association between different obesity-related indices and vitamin D deficiency in middle-aged and elderly population dwelled in Lanzhou city.Methods:From May, 2011 to September, 2012, middle-aged and elderly individuals with complete baseline data were included via randomly cluster sampling from 3 communities in Lanzhou. The subjects were divided into 4 subgroups by vitamin D levels and various obesity-related indices were compared across subgroups with the same gender. The relationship between the obesity-related indices and the severity of vitamin D deficiency was analyzed using Spearman correlation analysis, and the effects of different obesity-related indices on the severity of vitamin D deficiency was analyzed using multivariate logistic regression analysis.Results:A total of 9 437 residents were included. The overall prevalence of vitamin D deficiency was 97.7%. Compared with the group with lower vitamin D level, participants in the group with higher vitamin D level showed evidently lower body mass index (BMI), waist circumference (WC), lipid accumulation product (LAP), visceral adiposity index (VAI) and triglyceride/ high density lipoprotein cholesterol (TG/HDL-C) ratio in the total population and females, while only WC, LAP, VAI and TG/HDL-C in the males (all P<0.05). Spearman correlation analysis showed that BMI, WC, LAP, VAI and TG/HDL-C were positively correlated with the severity of vitamin D deficiency in the total population and the females, while only LAP, VAI and TG/HDL-C in the males (all P<0.05) . Multivariate logistic regression analysis showed that higher levels of these obesity related indices were correlated with more severe vitamin D deficiency in the total population and the females, while only higher LAP, VAI and TG/HDL-C in the males (all P<0.05). The effects of higher LAP was the most prominant in the total population ,the females and the males. Conclusion:Various obesity phenotypes are closely related to vitamin D deficiency in middle-aged and elderly women, while only visceral obesity and abnormal lipid metabolism are related to vitamin D deficiency in middle-aged and elderly men, with LAP being the most important influencing factor.

Objective:To explore the mechanism of highly expressed primary cilia in tibial growth plate chondrocytes accelerating chondrocytes differentiation in young rats with chronic renal failure (CRF).Methods:Forty male 4-week-old SD rats weighing (98±3) g were randomly divided into control group (intragastric administration with distilled water, n=20) and CRF group (intragastric administration with adenine suspension 150 mg·kg -1·d -1, n=20). All the young rats were sacrificed after continuous gavage for 6 weeks. The length of the growth plate was measured with histological sections. Immunofluorescence (IF) was used to detect the expression rate of primary cilia and the level of β-catenin, the key protein of Wnt/β-catenin signaling pathway in tibial growth plate chondrocytes. Chondrocytes isolated from growth plate in two groups were cultured in vitro to P3 generation, and the expression rate of primary cilia in chondrocytes, the levels of Indian hedgehog (IHH) and glycogen synthase kinase 3β (GSK3β) were detected by IF. Co-immunoprecipitation was used to detect the relationship between IHH and GSK3β. Results:Compared with the control group, the relative length of the growth plate was shorter in histological sections [(0.51±0.11) vs (1.00±0.08), t=16.11, P<0.001], the expression rate of primary cilia was higher [(26.3±5.5)% vs (7.6±1.9)%, t=14.37, P<0.001], and the level of β-catenin increased [(7.1±2.0) scores vs (3.6±1.0) scores, t=7.10, P<0.001] in CRF group. In vitro, the expression rate of primary cilia was higher in CRF group chondrocytes [(31.4±8.2)% vs (12.5±3.1)%, t=9.64, P<0.001] than that in control group. The level of IHH in CRF group increased than that in control group [(1 360±270) vs (310±84), t=16.61, P<0.001]. There was no significant difference in GSK3β level of chondrocytes between the two groups [(850±195) vs (780±140), t=1.30, P=0.200]. There was a direct interaction between IHH and GSK3β in CRF group chondrocytes. Conclusions:The expression levels of primary cilia and related protein IHH increase in tibial growth plate chondrocytes of CRF young rats. The IHH protein plays a direct interaction with GSK3β protein, Wnt/β-catenin signaling pathway antagonist, which leads to the activation of Wnt/β-catenin signaling pathway and final accelerated differentiation of chondrocytes. The rapid differentiation of chondrocytes causes the closing trend of growth plate.
