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.

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.

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.

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 explore the association of single nucleotide polymorphisms (SNPs) of the vitamin D receptor gene ( VDR) with circulating lipids considering gender differences. METHODS: Of the Han Chinese adults recruited from a health examination center for inclusion in the study, the circulating lipids, 25-hydroxyvitamin D (25OHD), and other parameters were measured. The VDR SNPs of Cdx2 (rs11568820), Fok1 (rs2228570), Apa1 (rs7975232), and Taq1 (rs731236) were genotyped with a qPCR test using blood DNA samples, and their associations with lipids were analyzed using logistic regression. RESULTS: In the female participants ( n = 236 with dyslipidemia and 888 without dyslipidemia), multiple genotype models of Fok1 indicated a positive correlation of B (not A) alleles with LDLC level ( P < 0.05). In the male participants ( n = 299 with dyslipidemia and 564 without dyslipidemia), the recessive model of Cdx2 and the additive and recessive models of Fok1 differed ( P < 0.05) between the HDLC-classified subgroups, respectively, and Fok1 BB and Cdx2 TT presented interactions with 25OHD in the negative associations with HDLC ( P < 0.05). CONCLUSION In the Chinese Han adults included in the study, the Fok1 B-allele of VDR was associated with higher LDLC in females, and the Fok1 B-allele and the Cdx2 T-allele of VDR were associated with lower HDLC in males. The interaction of VD and Fok1 BB or Cdx2 TT in males synergistically decreased HDLC levels.

OBJECTIVE: To compare the therapeutic effect on postmenopausal osteoporosis (PMOP) between Lingnan Chen's needling technique and calcitriol soft capsules and investigate the effect mechanism in view of serum growth hormone (GH) and insulin-like growth factor-1 (IGF-1). METHODS: Seventy patients of PMOP were randomized into an observation group (35 cases, 4 cases dropped off ) and a control group (35 cases, 3 cases dropped off ). The patients of both groups were treated with calcium carbonate D3 tablets orally (600 mg each time, once daily). In the observation group, acupuncture was delivered at Shenshu (BL 23), Pishu (BL 20), Guanyuan (CV 4), Sanyinjiao (SP 6), etc. with the specific reinforcing-reducing technique and qi-conducting technique of Lingnan Chen's acupuncture, once every two days, three times a week. In the control group, calcitriol soft capsules were taken orally, 0.25 μg each time, twice a day. The intervention measures of two groups all lasted 12 weeks. Before and after treatment, the bone mineral density (BMD), the levels of serum GH and IGF-1 were assessed in two groups. Before treatment and 4, 8 and 12 weeks after treatment, TCM symptoms score and the MOS item short form health survey (SF-36) score were evaluated and the therapeutic effects were compared between groups. RESULTS: In both within-group and between-group comparisons, the difference in BMD was not significant before and after treatment (P>0.05). After treatment, the levels of serum GH and IGF-1 were increased in the observation group (P<0.05), and higher than the control group (P<0.05). After 4, 8 and 12 weeks of treatment, the scores of TCM symptoms were reduced in both groups compared with those before treatment (P<0.05), and the score in the observation group was lower than that in the control group (P<0.05). After 4, 8 and 12 weeks of treatment, except the score of general health 4 weeks after treatment in the control group, the scores of the other domains in SF-36 were increased in both groups compared with those before treatment (P<0.05). After 12 weeks of treatment, except the score for the general health and social functions, the scores of the other domains of SF-36 in the observation group were all higher than those in the control group (P<0.05). The total effective rate was 83.9% (26/31) in the observation group, higher than 59.4% (19/32) in the control group (P<0.05). CONCLUSION Lingnan Chen's needling technique is effective on postmenopausal osteoporosis. This therapy may relieve the symptoms of osteoporosis and improve the quality of life, better than calcitriol soft capsules, and the effect mechanism may be related to the up-regulation of serum GH and IGF-1 in the patients.
