Objective: To systematically evaluate the correlation between selenium in the body and the risk of chronic kidney disease (CKD), so as to provide insights into CKD prevention and control. Methods: Publications pertaining to the correlation between selenium level and CKD were retrieved from electronic databases, including CNKI, WanFang Data, PubMed and Web of Science from inception until July 28, 2022. Meta-analysis was performed using the software Stata 16.0, and all measures were expressed with standardized mean difference (SMD) and its 95%CI. The source of heterogeneity was analyzed using subgroup analysis and meta-regression, and sensitivity analysis was performed using the leave-one-out method. In addition, the publication bias was evaluated with d funnel plot, Egger's test and Begg's test, and the robustness of the result was evaluated using the trim and filling method. Results: A total of 2 990 publications were screened, and 63 eligible publications were included in the final analysis, including 18 cross-sectional studies, 40 case-control studies, 2 cohort studies and 3 randomized controlled trials (RCTs), which covered 5 099 CKD patients and 6 334 controls. Meta-analysis showed lower selenium levels in CKD patients than in controls (SMD=-1.828, 95%CI: -2.132 to -1.523, P<0.001). Subgroup analysis showed lower selenium levels among CKD patients than among controls from Asia, Europe and multiple continents (P<0.05), and lower selenium levels were detected in patients undergoing conservative treatment, hemodialysis and peritoneal dialysis than in controls (P<0.05), while the selenium levels were significantly lower in CKD patients than in controls in cross-sectional studies, case-control studies and RCTs (P<0.05). The selenium level was significantly lower among CKD patients than among controls regardless of the study year, sample size and score for quality of publications (P<0.05). Sensitivity analysis showed robustness of this meta-analysis. Publication bias was identified by funnel plot, Begg's test and Egger's test, and the robustness of the result was found using the trim-and-fill method. Conclusion There may be a possible correlation between selenium and the risk of CKD.

Results The biological active OdDHL was synthesized successfully. OdDHL inhibited proliferation of P815 cells in a dose, and time dependent manner. It also induced apoptasis and intracellular calcium release in P815 cells. Conclusion Psendomonas aeruginosa quorum sensing molecule OdDHL induces apoptosis and intracellular calcium release in murine mast cell line P815.

Objective: To evaluate the association of smoking with the risk of ankylosing spondylitis (AS) using a Mendelian randomization (MR) approach. Methods: A total of 16 383 186 AS-associated single nucleotide polymorphisms (SNPs), 378 smoking initiation associated SNPs and 126 lifetime smoking score-associated SNPs were collected from three large-scale genome-wide association studies (GWAS). The association of smoking phenotypes with the risk of AS was examined using inverse-variance weighted (IVW) with AS as a outcome variable, smoking initiation and lifetime smoking score as exposure factors and SNPs with strong associations with smoking as instrumental variables, and sensitivity analyses were performed with maximum likelihood-based method, MR pleiotropy residual sum and outlier (MR-PRESSO) test and MR-Egger regression analysis. Results: A 33.5% increased risk of AS was found among genetically predicted smokers relative to non-smokers (OR=1.335, 95%CI: 1.059-1.682), and an increase in predicted lifetime smoking by per standard deviation resulted in a 101.4% increased risk of AS (OR=2.014, 95%CI: 1.341-3.024). The maximum likelihood-based method and MR-PRESSO test showed consistent correlated effect estimations and MR-Egger regression analysis identified no evidence of pleiotropy. Conclusion It is genetically predicted that smoking is associated with an increased risk of AS.

Objective: To examine the association between sleep and frailty using the bidirectional two-sample Mendelian randomization (MR) approach, so as to provide the basis for the prevention and intervention of frailty. Methods: The data on single nucleotide polymorphisms (SNP) related to sleep duration, insomnia and morning chronotype were collected from genome-wide association studies (GWAS) and meta-analysis of GWAS, involving 446 118, 1 331 010 and 697 828 participants, respectively. The frailty was evaluated using the frailty index, and the relevant SNP data were collected from a meta-analysis of GWAS involving 175 226 participants. A bidirectional MR analysis was performed using the inverse-variance weighted method. Sensitivity analyses employed the weighted median method, the maximum likelihood-based method, the MR-Egger regression, and the MR-PRESSO test. Results: Forward MR analysis showed that longer sleep duration (β=-0.170, 95%CI: -0.255 to -0.085) and morning chronotype (β=-0.036, 95%CI: -0.058 to -0.014) decreased the risk of frailty, while insomnia increased the risk of frailty (β=0.167, 95%CI: 0.149-0.184). Reverse MR analysis showed that frailty increased the risk of insomnia (OR=1.645, 95%CI: 1.278-2.117). Both bidirectional MR results were robust, which excluded the impact of heterogeneity and horizontal pleiotropy. Conclusion Sleep duration, insomnia, and morning chronotype are associated with frailty.

Tertiary lymphoid structure (TLS) is the ectopic lymphoid tissue around the chronic inflammatory site of tumor, infection diseases, autoimmunity diseases, organ transplantation and so on. TLS is regarded as the vital niche of antitumor immune response in tumor microenvironment for abundant immune cells, and is correlated with better clinical outcomes and immunotherapy response in most solid tumors. As a typical inflammation-driven cancer, hepatocellular carcinoma (HCC) is controversial with the influence of TLS on patients prognosis. In this paper, the composition, formation mechanism, recognition and clinical value of TLS in HCC were briefly reviewed.

OBJECTIVETo study the relationship between angiotensin converting enzyme (ACE) gene insertion/deletion (I/D) polymorphism and left ventricular mass (LVM) in newborns admitted to the neonatal intensive care unit (NICU).

METHODSSeventy-two newborns admitted to the NICU were enrolled. ACE genotypes were determined by genomic DNA which was isolated from heel-prick blood. Disease status of the newborns was evaluated by the Neonatal Critical Score (draft) on postnatal day 1. LVM and LVM index (LVMI) were evaluated by echocardiography on postnatal days 1-3.

RESULTSDD genotype was identified in 11 cases, ID genotype in 31 cases, and II genotype in 30 cases. There were no significant differences in clinical characteristics, critical score and body measurements in newborns with different genotypes. The DD genotype group showed significantly lower LVMI than the group with ID+II genotypes (29±4 g/m2 vs 35±8 g/m2; P<0.05).

CONCLUSIONSACE gene polymorphism is associated with the LVMI in newborns admitted to the NICU. The LVMI of DD genotype carriers is significantly lower than that of ID+II genotypes carriers, which suggests that D allele may be associated with the growth and development of left ventricular.

To explore the hematopoietic reconstitution and transplantation-related complications of two units of unrelated umbilical cord blood combined transplantation for the treatment of adult hematologic malignancies, one adult patient with chronic myelogenous leukemia received two units of unrelated umbilical cord blood combined transplantation. The conditioning regimen was busulfan and cyclophosphamide (Bu-Cy). GVHD prophylaxis regimen consisted of mycophenolate mofetil (MMF), cyclosporine A (CsA) and methotrexate (MTX). The patient received total nucleated cells 4.63 x 10(7)/kg with CD34+ cells 8.34 x 10(5)/kg. Engraftment was documented by the analysis of short tandem repeat with polymerase chain reaction (STR-PCR). The results showed that the STR-PCR analysis for peripheral blood at day 31, 46 and 71 after transplantation suggested that one of two units of cord blood were completely engrafted. The ANC > 0.5 x 10(9)/L in the patient occurred at day 23, blood platelet counts > 20 x 10(9)/L at day 33 and > 50 x 10(9)/L at day 47. The Philadelphia chromosome and bcr/abl fusion gene of the patient also turned to negative after engraftment. Acute GVHD grade II occurred at day 13 and cured after treatment. It is concluded that umbilical cord blood can be used in adult hematopoietic stem cell transplantation. Two or more units umbilical cord blood combined transplantation might be the way to solve the problem of the low counts of nucleated cells when be used for adult.
