Bone tuberculosis is one of the main lesions of extrapulmonary tuberculosis, and the affected site shows local pain and limited movement, and the severe patients face a higher risk of teratogenicity and disability. Especially in the context of the increasing spread of multidrug-resistant tuberculosis, it is particularly urgent to seek innovative treatment options. In recent years, vitamin D plays an important role in the prevention and treatment of bone tuberculosis, and the mechanism of action has been continuously explored. At the same time, vitamin D receptor gene polymorphism has also been found to be closely related to the susceptibility and risk of bone tuberculosis. This article reviewed the relationship between vitamin D and its receptor gene polymorphisms and the susceptibility to bone tuberculosis. It was found that vitamin D deficiency increased the susceptibility to bone tuberculosis in both adults and children, and multiple genotypes of vitamin D receptor had an effect on the susceptibility to bone tuberculosis, especially FokⅠ genotype. It may also be one of the reasons for the increase in the number of bone tuberculosis. Through the study of the relationship between vitamin D and its receptor gene polymorphism and the susceptibility to bone tuberculosis, some factors inducing bone tuberculosis can be avoided, and related new drugs can be more targeted, such as vitamin D supplements, gene receptor related antagonists, etc. To provide more systematic and targeted strategies for the prevention and treatment of bone tuberculosis.

OBJECTIVES: To study the significance of serum 25-hydroxyvitamin D₃ [25-(OH)D₃] level in the clinicopathological characteristics and prognosis of children with immunoglobulin A vasculitis nephritis (IgAVN). METHODS: A retrospective analysis was conducted on the clinical data of children with IgAVN who underwent renal biopsy at Suzhou Hospital Affiliated to Anhui Medical University and Jinling Hospital of the Medical School of Nanjing University from June 2015 to June 2020. Based on serum 25-(OH)D₃ level, the patients were divided into a normal group and a lower group. The clinicopathological characteristics and follow-up data of the two groups were collected and compared. RESULTS: A total of 359 children with IgAVN were included. Compared to the normal group (62 cases), the lower group (297 cases) exhibited higher incidences of hematochezia and gross hematuria, higher levels of serum creatinine, blood urea nitrogen, urinary retinol protein, urinary N-acetyl-β-D-glucosaminidase, and quantitative urinary protein, and a longer duration from renal biopsy to urinary protein becoming negative, as well as lower estimated glomerular filtration rate and albumin level (P<0.05). Renal pathology in the lower group showed a higher occurrence of tubular interstitial injury, crescent formation, segmental sclerosis in glomeruli, and inflammatory cell infiltration in the renal interstitium compared to the normal group (P<0.05). Survival analysis indicated that the cumulative renal survival rate was lower in the lower group (P<0.05). Multivariate Cox regression analysis revealed that low serum 25-(OH)D₃ level is an independent risk factor for poor prognosis in children with IgAVN. CONCLUSIONS Children with IgAVN and low serum 25-(OH)D₃ level have relatively severe clinicopathological manifestations. Low serum 25-(OH)D₃ level is an independent risk factor for poor prognosis in children with IgAVN.

OBJECTIVE: To assess the safety and topical efficacy of prim-O-glucosylcimifugin (POG) and investigate the molecular mechanisms of its therapeutic effects in atopic dermatitis (AD). METHODS: The effects of POG on human keratinocyte cell viability and its anti-inflammatory properties were evaluated using cell counting kit-8 assay and reverse transcription-quantitative polymerase chain reaction (RT-qPCR). Subsequently, the impact of POG on the differentiation of cluster of differentiation (CD) 4⁺ T cell subsets, including T-helper type (Th) 1, Th2, Th17, and regulatory T (Treg), was examined through in vitro experiments. Network pharmacology analysis was used to elucidate POG's therapeutic mechanisms. Furthermore, the therapeutic potential of topically applied POG was further evaluated in a calcipotriol-induced mouse model of AD. The protein and transcript levels of inflammatory markers, including cytokines, lymphocyte-specific protein tyrosine kinase (Lck) mRNA, and LCK phosphorylation (p-LCK), were quantified using immunohistochemistry, RT-qPCR, and Western blot analysis. RESULTS: POG was able to suppress cell proliferation and downregulate the transcription of interleukin 4 (Il4) and Il13 mRNA. In vitro experiments indicated that POG significantly inhibited the differentiation of Th2 cells, whereas it exerted negligible influence on the differentiation of Th1, Th17 and Treg cells. Network pharmacology identified LCK as a key therapeutic target of POG. Moreover, the topical application of POG effectively alleviated skin lesions in the calcipotriol-induced AD mouse models without causing pathological changes in the liver, kidney or spleen tissues. POG significantly reduced the levels of Il4, Il5, Il13, and thymic stromal lymphopoietin (Tslp) mRNA in the AD mice. Concurrently, POG enhanced the expression of p-LCK protein and Lck mRNA. CONCLUSION Our research revealed that POG inhibits Th2 cell differentiation by promoting p-LCK protein expression and hence effectively alleviates AD-related skin inflammation.

OBJECTIVES: To study the correlation between 25-hydroxyvitamin D [25-(OH)D] and nephroblastoma in children and its value in assessing the prognosis of the disease. METHODS: A total of 50 children with nephroblastoma who were admitted from January 2018 to December 2022 were included as the nephroblastoma group, and according to the postoperative pathological type, they were divided into a good prognosis group with 38 children and a poor prognosis group with 12 children. A total of 50 healthy children who underwent physical examination during the same period of time served as the healthy control group. The above groups were compared in terms of serum creatinine and 25-(OH)D level. A Spearman correlation analysis was used to investigate the correlation between serum 25-(OH)D level and therapeutic effect reaction. A multivariate logistic regression analysis was used to identify the risk factors affecting the prognosis of nephroblastoma in children. RESULTS: The nephroblastoma group had significantly lower levels of serum creatinine and 25-(OH)D than the healthy control group (P<0.05). Compared with the good prognosis group, the poor prognosis group had a significantly larger tumor diameter, a significantly higher proportion of children with stage III-IV tumors, a significantly higher rate of tumor metastasis, and significantly lower serum levels of creatinine and 25-(OH)D (P<0.05). The Spearman correlation analysis showed that serum 25-(OH)D level was negatively correlated with therapeutic effect reaction (r_s=-0.685, P<0.001). The multivariate logistic regression analysis showed that tumor diameter ≥10 cm, stage III-IV tumors, presence of tumor metastasis, and 25-(OH)D <19 ng/mL were closely associated with the poor prognosis of nephroblastoma in children (P<0.05). Serum 25-(OH)D level had an area under the curve of 0.805 (95%CI: 0.706-0.903, P<0.001) in evaluating the prognosis of nephroblastoma in children, with a Youden index of 0.512, a sensitivity of 0.938, and a specificity of 0.575 at the optimal cut-off value of 1.764 ng/mL. CONCLUSIONS There is a significant correlation between 25-(OH)D level and the prognosis of nephroblastoma in children, and 25-(OH)D can be used for prognosis prediction.

An effective therapeutic regimen for hepatic fibrosis requires a deep understanding of the pathogenesis mechanism. Hepatic fibrosis is characterized by activated hepatic stellate cells (aHSCs) with an excessive production of extracellular matrix. Although promoted activation of HSCs by M2 macrophages has been demonstrated, the molecular mechanism involved remains ambiguous. Herein, we propose that the vitamin D receptor (VDR) involved in macrophage polarization may regulate the communication between macrophages and HSCs by changing the functions of exosomes. We confirm that activating the VDR can inhibit the effect of M2 macrophages on HSC activation. The exosomes derived from M2 macrophages can promote HSC activation, while stimulating VDR alters the protein profiles and reverses their roles in M2 macrophage exosomes. Smooth muscle cell-associated protein 5 (SMAP-5) was found to be the key effector protein in promoting HSC activation by regulating autophagy flux. Building on these results, we show that a combined treatment of a VDR agonist and a macrophage-targeted exosomal secretion inhibitor achieves an excellent anti-hepatic fibrosis effect. In this study, we aim to elucidate the association between VDR and macrophages in HSC activation. The results contribute to our understanding of the pathogenesis mechanism of hepatic fibrosis, and provide potential therapeutic targets for its treatment.

OBJECTIVE: To investigate the expression, clinical significance and prognosis of vitamin D receptor (VDR) gene and NF-κB pathway in children with acute lymphoblastic leukemia (ALL). METHODS: Thirty children with definitive diagnoses of ALL from December 2018 to December 2021 were selected as ALL group, and 30 healthy children under physical examination were selected as control group. Peripheral blood of all study subjects was collected. The VDR and NF-κB mRNA and protein expressions were detected by real-time quantitative PCR and Western blot, respectively. The relationship between mRNA expression of the above genes and clinical characteristics of children was retrospectively analyzed. RESULTS: The relative expression of VDR mRNA in peripheral blood of children with ALL was significantly lower than that in the control group (P < 0.05), while NF-κB mRNA was higher (P < 0.001). The expression of NF-κB mRNA in ALL children with peripheral blood white blood cell count (WBC) < 50×10⁹/L at initial diagnosis was significantly higher than those with WBC≥50×10⁹/L (P < 0.01). The expression of NF-κB mRNA in ALL children with infection was significantly higher than that those without infection (P < 0.05). There were no significant differences in NF-κB mRNA expression between children with different sex, age, hemoglobin at initial diagnosis, platelet, immunologic typing, risk and induced response (P >0.05). CONCLUSION The expression of NF-κB is of value to diagnosis and prognosis of ALL in children.

Objective: To investigate the relationship between vitamin D receptor (VDR) gene polymorphisms and gestational diabetes mellitus (GDM) and provide evidence for the study of the mechanism of GDM. Methods: A case-control study design was used to study pregnant women who delivered in the obstetrics department of the First Hospital of Shanxi Medical University from March 1, 2012 to July 30, 2014. Of these, 334 cases were diagnosed with GDM and were matched 1∶1 by age, gestation time and residence to corresponding healthy controls. DNA genotyping was performed for the study subjects, and those with genotyping deletions >10% were excluded. Finally 323 cases and 320 controls were included in the study. Under co-dominant, dominant, recessive, and allele genetic models, unconditional logistic regression analysis on the relationship between VDR gene locus polymorphism and GDM was conducted. And software Haploview was used to analyze the relationship between haplotype and GDM. Results: At the genetic level, VDR gene was associated with the risk of developing GDM (P<0.05). After adjusting for pre-pregnancy body mass index, family history of diabetes, it was found that rs7967152 loci was associated with an increased risk of developing GDM (AC vs. AA, OR=1.58, 95%CI: 1.13-2.21; AC+CC vs. AA, OR=1.58, 95%CI: 1.15-2.18; C vs. A, OR=1.41, 95%CI: 1.10-1.82) and rs2238140 loci was associated with an increased risk of developing GDM (AA vs. GG, OR=2.24, 95%CI: 1.19-4.20; GA+AA vs. GG, OR=1.48, 95%CI: 1.07-2.03; A vs. G, OR=1.43, 95%CI: 1.11-1.83). Carrying rs2853564 locus AG genotype and AG+GG genotype (OR=1.46, 95%CI: 1.04-2.05; OR=1.45, 95%CI: 1.05-2.00) compared with carrying AA genotype and carrying rs2853566 locus AG genotype and AG+GG genotype (OR=1.43, 95%CI: 1.03-2.00; OR=1.41, 95%CI: 1.02-1.94) compared with carrying AA genotype were risk factors for GDM. Haplotype block consisting of rs1544410, rs7967152 in the VDR gene with GC haplotype was a risk factor for GDM(OR=1.50, 95%CI: 1.15-1.97). Conclusions: VDR gene rs7967152, rs2238140, rs2853564, rs2853566 locus polymorphisms and block (rs1544410, rs7967152) GC haplotype were associated with an incrased risk of developing GDM.

OBJECTIVE: To identify the miRNAs targeting vitamin D receptor (VDR) gene and their effect on parathyroid hormone (PTH) secretion in secondary hyperparathyroidism. METHODS: Primary parathyroid cells with secondary hyperparathyroidism were isolated by collagenase digestion and cultured. The miRNAs targeting VDR were screened by bioinformatics methods and full transcriptome sequencing, and dual-luciferase reporter assay was used to verify the targeting relationship between VDR and the screened miRNA. The effects of overexpression or inhibition of the candidate miRNA on VDR mRNA and protein expressions and PTH secretion were evaluated using qRT-PCR and Western blotting. The expression levels of the candidate miRNAs and VDR mRNA in clinical specimens of parathyroid tissues were verified by qRT-PCR, and the expression of VDR protein was detected by immunohistochemistry. RESULTS: We successfully isolated primary parathyroid cells. Dual-luciferase reporter assay verified the targeting relationship of hsa-miR-149-5p, hsa-miR-221-5p, hsa-miR-222-3p, hsa-miR-29a-5p, hsa-miR-301a-5p, hsa-miR-873-5p, hsa-miR-93-3p with VDR, and among them, the overexpression of hsa-miR-149-5p and hsa-miR-301a-5p significantly increased PTH secretion in the parathyroid cells. In patients with secondary hyperparathyroidism, hsa-miR-149-5p was highly expressed in the parathyroid tissues (P=0.046), where the expressions of VDR mRNA (P=0.0267) and protein were both decreased. CONCLUSION The two miRNAs, hsa-miR-149-5p and hsa-miR-301a-5p, may promote the secretion of PTH in patients with secondary hyperparathyroidism by down-regulating the expression of VDR gene.
