OBJECTIVE To study the pharmacokinetics and tissue distribution of cannabidiol(CBD)-cholesterol succinate monoester-g-carboxymethyl chitosan (CCMC) nano-micelles in rats, and to evaluate its anti-inflammatory effect. METHODS CBD- CCMC nano-micelles were prepared by dialysis method and the properties were characterized. SD rats were divided into CBD group and CBD-CCMC nano-micelles group with 6 rats in each group. The rats were given 100 mg/kg CBD and CBD-CCMC nano- micelle by intragastric administration, respectively (based on the CBD load). Blood was collected from the posterior ophthalmic venous plexus at 0.5, 1, 1.33, 1.5, 1.75, 2, 4, 8, 24, 48 h after administration. The heart, liver, spleen, lung, kidney and muscle tissues of rats were separated at 0.25, 1.5, 10 and 24 h after administration of CBD and CBD-CCMC nano-micelle with the same dose. The drug content in plasma and tissues was determined, the pharmacokinetic parameters were calculated, and the tissue distribution was analyzed. The inflammatory model of Caco-2 cells was induced by lipopolysaccharide, after 24 h of treatment with 5, 10, and 15 µg/mL CBD and CBD-CCMC nanomicelles (based on loaded CBD), its anti-inflammatory activity was investigated by measuring cell viability, transepithelial electrical resistance (TEER) and inflammatory cytokines IL-1β, IL-8 and TNF-α. RESULTS The prepared CBD- CCMC nano-micelles had a particle size of (230.6±1.8) nm, a polydispersity index of 0.170±0.053, a Zeta potential of (-13.5± 1.2) mV, an encapsulation rate of (86.35±0.56)% and a drug loading of (9.18±0.32)%, respectively; the solubility was 68.240 μg/mL. The pharmacokinetic results showed that the AUC0-48 h, AUC0-∞, half-life time and peak concentration of CBD-CCMC nano- micelle group were significantly increased/extended compared with CBD group (P<0.05 or P<0.01). The results of the tissue distribution study showed that at the same time point, the drug distribution concentration of CBD-CCMC nanomicelles in the rat tissue was higher than that in the CBD group. Research on anti-inflammatory effects shows that compared with CBD of the same mass concentration, CBD-CCMC nano-micelles can significantly increase cell viability (P<0.05 or P<0.01), enhance TEER, and reduce the levels of IL-8, IL-1β and TNF-α in cells (P<0.01), and the secretion levels of inflammatory cytokines IL-8, IL-1β and TNF- α were significantly decreased (P<0.01). CONCLUSIONS CBD-CCMC nano-micelles can increase the plasma concentration and tissue distribution concentration of CBD, and improve anti-inflammatory activity of CBD.

Background::The serum vitamin D level varies widely by population, and studies have linked vitamin D levels with the risk of type 2 diabetes mellitus (T2DM). However, the relationship is inconsistent and the impact of vitamin D on T2DM among East Chinese adults is unclear. The study aimed to investigate the association between serum 25-hydroxyvitamin D (25[OH]D) levels and the risk of T2DM and evaluated whether the association is modified by genetic predisposition.Methods::In the Survey on Prevalence in East China for Metabolic Diseases and Risk Factors (SPECT-China) cohort, 1862 participants free of T2DM at baseline were included. A weighted genetic risk score was calculated with 28 variants associated with T2DM. Hierarchical logistic models were used to examine the association of serum 25(OH)D and genetic risk with T2DM.Results::After a 5-year follow-up, 132 cases of T2DM were documented. We observed no significant association between quartiles of serum 25(OH)D and T2DM risk after multivariable adjustment (χ 2 = 0.571, Pfor trend = 0.426). Compared to those in the lowest quartile of 25(OH)D, the odds ratios (ORs) (95% confidence interval [CI]) for participants with increased quartiles were 1.29 (0.74-2.25), 1.35 (0.77-2.36), and 1.27 (0.72-2.24), respectively. We observed a positive association of glycated hemoglobin (HbA1c) with 25(OH)D at baseline (β = 1.752, P = 0.001) and after follow-up (β = 1.385, P = 0.003), and a negative association of ln conversion homeostasis model assessment (HOMA)-β with 25(OH)D at baseline (β = -0.982, P = 0.021). There was no significant interaction between 25(OH)D and diabetes genetic predisposition on the risk of T2DM (χ 2 = 2.710, Pfor interaction = 0.100). The lowest OR (95% CI) of T2DM was among participants with low genetic risk and the highest quartile of 25(OH)D (0.17 [0.05–0.62]). Conclusion::Serum 25(OH)D may be irrelevant to the risk of incident T2DM among East Chinese adults regardless of genetic predisposition.

Background::Prenatal and postnatal factors may have joint effects on cardiovascular health, and we aimed to assess the joint association of birth weight and ideal cardiovascular health metrics (ICVHMs) prospectively in adulthood with incident cardiovascular disease (CVD).Methods::In the UK Biobank, 227,833 participants with data on ICVHM components and birth weight and without CVD at baseline were included. The ICVHMs included smoking, body mass index, physical activity, diet information, total cholesterol, blood pressure, and hemoglobin A1c. The Cox proportional hazards model was used to estimate the hazard ratios (HRs) and 95% confidence intervals (CIs) in men and women.Results::Over a median follow-up period of 13.0 years (2,831,236 person-years), we documented 17,477 patients with incident CVD. Compared with participants with birth weights of 2.5-4.0 kg, the HRs (95% CIs) of CVD among those with low birth weights was 1.08 (1.00-1.16) in men and 1.23 (1.16-1.31) in women. The association between having a birth weight <2.5 kg and CVD risk in men was more prominent for those aged <50 years than for those of older age ( P for interaction = 0.026). Lower birth weight and non-ideal cardiovascular health metrics were jointly related to an increased risk of CVD. Participants with birth weights <2.5 kg and ICVHMs score 0-1 had the highest risk of incident CVD (HR [95% CI]: 3.93 [3.01-5.13] in men; 4.24 [3.33-5.40] in women). The joint effect (HR [95% CI]: 1.36 [1.17-1.58]) could be decomposed into 24.7% (95% CI: 15.0%-34.4%) for a lower birth weight, 64.7% (95% CI: 56.7%-72.6%) for a lower ICVHM score, and 10.6% (95% CI: 2.7%-18.6%) for their additive interaction in women. Conclusions::Birth weight and ICVHMs were jointly related to CVD risk. Attaining a normal birth weight and ideal ICVHMs may reduce the risk of CVD, and a simultaneous improvement of both prenatal and postnatal factors could further prevent additional cases in women.

Background::Life’s Simple 7, the former construct of cardiovascular health (CVH) has been used to evaluate adverse non-communicable chronic diseases (NCDs). However, some flaws have been recognized in recent years and Life’s Essential 8 has been established. In this study, we aimed to analyze the association between CVH defined by Life’s Essential 8 and risk of 44 common NCDs and further estimate the population attributable fractions (PAFs) of low-moderate CVH scores in the 44 NCDs.Methods::In the UK Biobank, 170,726 participants free of 44 common NCDs at baseline were included. The Life’s Essential 8 composite measure consists of four health behaviours (diet, physical activity, nicotine exposure, and sleep) and four health factors (body mass index, non-high density lipoprotein cholesterol, blood glucose, and blood pressure), and the maximum CVH score was 100 points. CVH score was categorized into low, moderate, and high groups. Participants were followed up for 44 NCDs diagnosis across 10 human system disorders according to the International Classification of Diseases 10th edition (ICD-10) code using linkage to national health records until 2022. Cox proportional hazard models were used in this study. The hazard ratios (HRs) and PAFs of 44 NCDs associated with CVH score were examined.Results::During the median follow-up of 10.85 years, 58, 889 incident NCD cases were documented. Significant linear dose-response associations were found between higher CVH score and lower risk of 25 (56.8%) of 44 NCDs. Low-moderate CVH (<80 points) score accounted for the largest proportion of incident cases in diabetes (PAF: 80.3%), followed by gout (59.6%), sleep disorder (55.6%), chronic liver disease (45.9%), chronic kidney disease (40.9%), ischemic heart disease (40.8%), chronic obstructive pulmonary disease (40.0%), endometrium cancer (35.8%), lung cancer (34.0%), and heart failure (34.0%) as the top 10. Among the eight modifiable factors, overweight/obesity explained the largest number of cases of incident NCDs in endocrine, nutritional, and metabolic diseases (35.4%), digestive system disorders (21.4%), mental and behavioral disorders (12.6%), and cancer (10.3%); however, the PAF of ideal sleep duration ranked first in nervous system (27.5%) and neuropsychiatric disorders (9.9%).Conclusions::Improving CVH score based on Life’s Essential 8 may lower risk of 25 common NCDs. Among CVH metrics, avoiding overweight/obesity may be especially important to prevent new cases of metabolic diseases, NCDs in digestive system, mental and behavioral disorders, and cancer.

Objective:To identify the differentially expressed long-chain non-coding RNA(lncRNA) and mRNA using ribonucleic acid sequencing(RNA-seq), and construct a competing endogenous RNA(ceRNA) regulatory network in mice with sepsis-associated encephalopathy.Methods:Ten clean-grade healthy male C57BL/6 mice, aged 6-8 weeks, weighing 20-25 g, were divided into 2 groups( n=5 each) using a random number table method: sham operation group(group Sham) and sepsis group(group Sepsis). Sepsis was induced by cecal ligation and puncture(CLP) in group Sepsis, while group Sham only underwent laparotomy without CLP. Morris water maze test and contextual fear conditioning test were performed to detect the cognitive function on 1 day before CLP and 3 days after CLP. Three mice were randomly sacrificed in group Sham, and 3 mice with the worst results in the cognitive function test were sacrificed in group Sepsis. The hippocampal tissues were obtained for RNA-seq via the BGISEQ-500 platform, and the differentially expressed mRNA and lncRNA were identified. The differentially expressed mRNAs and lncRNAs were visualized and analyzed by Dr. Tom platform provided by Shenzhen BGI Technology Service Co., Ltd., and the ceRNA regulatory network was constructed using the online visualization tool Cytoscape software. Results:Compared with group Sham, the escape latency was significantly prolonged, and the percentage of time of staying at the target quadrants and percentage of time spent freezing were decreased in group Sepsis( P<0.05). A total of 62 differentially expressed lncRNAs were obtained from RNA-seq, of which the expression of 45 lncRNAs was up-regulated and the expression of 17 lncRNAs was down-regulated.There were 282 differentially expressed mRNAs identified from RNA-seq, of which the expression of 173 mRNAs was up-regulated, and the expression of 109 mRNAs was down-regulated.Gene Ontology enrichment analysis revealed that the differentially expressed mRNAs were involved in biological processes such as memory, learning or memory, inflammatory responses, regulation of aging-related behavioral decline, and regulation of synaptic plasticity. Kyoto Encyclopedia of Genes and Genomes pathway enrichment analysis showed that differentially expressed mRNAs were enriched in IL-17 signaling pathway, TNF signaling pathway, NF-κB signaling pathway and etc. KDA analysis was performed on the differentially expressed mRNAs to identify the key driver genes, and the results showed that Ch25h, Il6ra, Lcn2, Sgk1, Nr4a3, Osm, Saa3, Ccl7, Sqle, Dhcr24 were the key SAE genes.A competing endogenous RNA regulatory network was successfully constructed based on 9 lncRNAs, 28 mRNAs and 134 miRNAs in the hippocampus of mice with SAE. Conclusions:The results of RNA-seq find that 10 mRNAs including Ch25h, Il6ra, Lcn2, Sgk1, Nr4a3, Osm, Saa3, Ccl7, Sqle, Dhcr24 and lncRNAs such as Rian, Gm35874 and Gm34347 are key genes regulating SAE in mice. Meanwhile, a ceRNA regulatory network based on lncRNA-miRNA-mRNA is successfully constructed in the hippocampus of mice with SAE.

BACKGROUND:
The association between sex hormone-binding globulin (SHBG) and renal function has rarely been reported in men. We aimed to investigate the above association in a community-based Chinese population.
METHODS:
A total of 5027 men were included from the survey on prevalence for metabolic diseases and risk factors, which is a population-based study conducted from 2014 to 2016 in Eastern China. The estimated glomerular filtration rate (eGFR) was calculated according to the chronic kidney disease Epidemiology Collaboration equation. Low eGFR was defined as eGFR <60 mL·min -1 ·1.73 m -2 .
RESULTS:
After adjusting for age, smoking, metabolic factors, and testosterone, through increasing quartiles of SHBG, a significantly positive association between SHBG quartiles and eGFR was detected in men (Q1 vs. Q4, β -2.53, 95% confidence interval -3.89, -1.17, Ptrend < 0.001). Compared with the highest quartile of SHBG, SHBG in the lowest quartile was associated with 96% higher odds of low eGFR (odds ratio 1.96, 95% confidence interval 1.10, 3.48) in the model after full adjustment. According to the stratified analyses, the associations between a 1-standard deviation increase in serum SHBG and the prevalence of low eGFR were significant in men aged ≥60 years old, waist circumference <90 cm, diabetes (no), hypertension (yes), dyslipidemia (no), and nonalcoholic fatty liver disease (no).
CONCLUSIONS
Lower serum SHBG levels were significantly associated with lower eGFR and a higher prevalence of low eGFR in Chinese men independent of demographics, lifestyle, metabolic-related risk factors, and testosterone. Large prospective cohort and basic mechanistic studies are warranted in the future.

10.Progress of the relationship between group 2 innate lymphoid cells and bronchial asthma
International Journal of Pediatrics 2022;49(7):465-469
Group 2 innate lymphoid cells (ILC2) are a newly identified subset of innate immune cells which are closely associated with the development of bronchial asthma(asthma). ILC2 develops from lymphoid progenitor cells in the bone marrow under the regulation of retinoid-related nuclear orphan receptor α (RORα) and GA-TA-binding protein-3 (GATA-3). ILC2 can be activated by IL-25, IL-33, thymic stromal lymphopoietin (TSLP) and lipid mediator and produce Th2 cytokines, such as IL-4, IL-5, IL-9 and IL-13, which activate innate immune cells and adaptive immune cells to participate in asthma inflammation.ILC2 may be a therapeutic target for asthma, providing new possibilities for the prevention and treatment.
