Objective Tissue uptake and distribution of nano-/microplastics was studied at a single high dose by gavage in vivo.Methods Fluorescent microspheres (100 nm, 3 μm, and 10 μm) were given once at a dose of 200 mg/(kg·body weight). The fluorescence intensity (FI) in observed organs was measured using the IVIS Spectrum at 0.5, 1, 2, and 4 h after administration. Histopathology was performed to corroborate these findings.Results In the 100 nm group, the FI of the stomach and small intestine were highest at 0.5 h, and the FI of the large intestine, excrement, lung, kidney, liver, and skeletal muscles were highest at 4 h compared with the control group (P < 0.05). In the 3 μm group, the FI only increased in the lung at 2 h (P < 0.05). In the 10 μm group, the FI increased in the large intestine and excrement at 2 h, and in the kidney at 4 h (P < 0.05). The presence of nano-/microplastics in tissues was further verified by histopathology. The peak time of nanoplastic absorption in blood was confirmed.Conclusion Nanoplastics translocated rapidly to observed organs/tissues through blood circulation;however, only small amounts of MPs could penetrate the organs.

Objective:To investigate the effects of Curcumol on the malignant biological characteristics of acute myeloid leukemia (AML)cells and its molecular mechanism,and to provide theoretical and experimental evidence for the anti-leukemia treatment of traditional Chinese medicine.Methods:After the AML cell lines HL-60 and KG-1 cells were treated different concentrations of with Curcumol.The proliferation activity of cells was detected by CCK-8 method,and the expression changes of apoptotic proteins and PI3 K/AKT signaling pathway proteins were detected by Western blot. Real-time quantitative fluorescence polymerase chain reaction (RT-qPCR ) was used to detect the expression of Caspase family mRNA.Results:Curcumol could inhibit the proliferation and induce apoptosis of HL-60 and KG-1 cells,promote apoptosis by up-regulating the expression of Bax and down-regulating the expression of Bcl-2 protein (P<0.05).When Curcumol interferes with HL-60 and KG-1 cells,it can also induce programmed cell death of AML by inhibiting PI3 K/AKT signaling pathway.In addition,after the intervention of Curcumol,the expression of Caspase 3,Caspase 6,Caspase 8 and Caspase 9 were up-regulated in HL-60 cells (P<0.05 ),the expression of Caspase 3,Caspase 8 and Caspase 9 were significantly up-regulated in KG-1 cells (P<0.01),while the expression of Caspase 6 was weakly affected (P<0.05 ),but low concentration of Curcumol (<60 μg/ml)had no effect on the expression of Caspase 6 in KG-1 cells (P>0.05).Conclusion:Curcumol may mediate the programmed death of AML cells by inhibiting the PI3K/AKT signaling pathway,affecting the expression of Bcl-2 family proteins,and promoting the activation of core members of Caspase family,so as to play an anti-leukemia role.

Sepsis-induced liver injury (SILI) is an important cause of septicemia deaths. BaWeiBaiDuSan (BWBDS) was extracted from a formula of Panax ginseng C. A. Meyer, Lilium brownie F. E. Brown ex Miellez var. viridulum Baker, Polygonatum sibiricum Delar. ex Redoute, Lonicera japonica Thunb., Hippophae rhamnoides Linn., Amygdalus Communis Vas, Platycodon grandiflorus (Jacq.) A. DC., and Cortex Phelloderdri. Herein, we investigated whether the BWBDS treatment could reverse SILI by the mechanism of modulating gut microbiota. BWBDS protected mice against SILI, which was associated with promoting macrophage anti-inflammatory activity and enhancing intestinal integrity. BWBDS selectively promoted the growth of Lactobacillus johnsonii (L. johnsonii) in cecal ligation and puncture treated mice. Fecal microbiota transplantation treatment indicated that gut bacteria correlated with sepsis and was required for BWBDS anti-sepsis effects. Notably, L. johnsonii significantly reduced SILI by promoting macrophage anti-inflammatory activity, increasing interleukin-10⁺ M2 macrophage production and enhancing intestinal integrity. Furthermore, heat inactivation L. johnsonii (HI-L. johnsonii) treatment promoted macrophage anti-inflammatory activity and alleviated SILI. Our findings revealed BWBDS and gut microbiota L. johnsonii as novel prebiotic and probiotic that may be used to treat SILI. The potential underlying mechanism was at least in part, via L. johnsonii-dependent immune regulation and interleukin-10⁺ M2 macrophage production.

Objectives: In order to provide valuable information for the diagnosis and treatment of dermatitis, the prevalence rate and trend changes of common allergens in patients with allergic skin diseases in Beijing City were investigated and analyzed. Methods: This study was a retrospective data collection study. A total of 2 822 patients diagnosed with moderate to severe atopic dermatitis with allergen examinations were collected from Peking University First Hospital from 2017 to 2021, most of them were adults, and 83%(2 340/2 822) were over 18 years old. The ImmunoCAP fluorescent enzyme-linked immunoassay system was used to quantify specific IgE. The positive rate of each allergen was counted according to age, gender and year. The epidemiological characteristics and trends were analyzed. Results: In the past five years, 22 503 allergen-specific IgE test data were collected, and the positive rate of allergens in 40%(1 122/2 822) of the 2 822 patients was mainly multiple sensitization, the positive rate of allergens and multiple sensitization rates were the highest in people aged 13-18 years old. The 2 822 patients were dominated by inhaled allergens, and the highest positive rate was inhaled mixture (29.3%). The top five positive rates of inhaled allergens were Dermatophagoides farina (26.7%), Dermatophagoides pteronyssinus (25.5%), Mugwort (23.9%), Birch pollen (19.2%) and Siberian cocklebur (18.2%). The top five positive rates of food allergens were shrimp (15.2%), peanut (14.8%), sesame (14.7%), wheat (13.2%) and milk (13.1%). Analysis of the positive rate of allergens in different age groups showed except for the positive rate of birch pollen peaked at 3-12 years old, other inhaled allergens were the highest food allergens in 13-18 years old. Among food allergens, the positive rates of fx5, milk, egg and wheat were the highest in <3 years old, the positive rate decreased gradually with age, and the positive rate of other food allergens peaked at 13-18 years old, and the shrimp and crab was the highest in adult. The positive rate of various allergens in the 2 822 patients showed little difference between male and female and the male was slightly higher than female. In the past five years, the positive rate of allergens has been on the rise. The changes of inhaled allergens in cat/dog hair dander, Dermatophagoides farina and cicadas were large, while the positive rate of food allergens was stable. Conclusions: The etiology of the allergic skin diseases is complex, which may be related to allergen exposure, heredity, immunity, environmental factors, abnormal skin barrier function, etc. This study showed the distribution of allergens in patients with allergic skin diseases in Beijing City to a certain extent. It provided epidemiological data and clinical evidence for the prevention and treatment of allergic diseases.
