ObjectiveTo investigate the inhibitory effect of Huoluo Xiaolingdan on triple negative breast cancer (TNBC) in mice through its regulation of TCF1+CD8+ stem cell-like T cells infiltration. MethodsA mouse model of TNBC was established and the mice were randomly divided into the model group, low-dose (3.9 g·kg-1), medium-dose (7.8 g·kg-1) and high-dose (15.6 g·kg-1) Huoluo Xiaolingdan groups, and anti-PD-1 antibody treatment group. Each group was given a dose of 0.01 mL·g-1, while the model group and the anti-PD-1 treatment group were also given an equivalent volume of normal saline. The drug was administered for 21 days. In the anti-PD-1 antibody group, mice were intraperitoneally injected with 100 μg of mouse anti-PD-1 antibody twice a week, for a total of five injections. The tumor volume, survival time and tumor mass were measured at different time points. Hematoxylin-eosin (HE) staining was used to observe the histological changes of the tumor. The expression of CD8+T cells and TCF1+CD8+ stem-like T cells in tumor tissues was detected by immunohistochemistry and immunofluorescence staining. Flow cytometry was used to detect the difference of immune cell subsets in tumors and the expression difference of TCF1+CD8+ stem cell-like T cells in tumors and peripheral blood. The expression level of PD-L1 in tumor tissues was detected by Western blot. ResultsCompared with model group, the tumor volume and mass of in low-, medium- and high-dose Huoluo Xiaolingdan groups and anti-PD-1 group were decreased (P<0.05, P<0.01). The median survival time of mice in low-, medium- and high-dose Huoluo Xiaolingdan groups and anti-PD-1 group was as follows: 27.00 days (95%CI, 0.45-2.65), 31.00 days (95%CI, 0.32-1.89), 34.00 days (95%CI, 0.40-2.33), and 35.00 days (95%CI, 0.42-2.47). All of them were higher than that of the model group [24.50 days (95%CI, 0.37-10.5)]. Flow cytometry showed that compared with the model group, the proportion and number of infiltrating CD8+ T cells in tumor were increased in low-, medium- and high-dose Huoluo Xiaolingdan groups and anti-PD-1 group (P<0.05, P<0.01), while the proportion of tumor regulatory T cells (Treg) and M2 macrophages decreased (P<0.05). Compared with the model group, the proportion of IFN-γ+CD8+ T and GrzB+CD8+ T cells in tumors in low-, medium- and high-dose Huoluo Xiaolingdan groups and anti-PD-1 group was increased (P<0.01), and the proportion of TCF1+CD8+ T cells in tumor and peripheral blood was also increased. Immunofluorescence staining further showed that the number of TCF1+CD8+ T cells in tumor tissues increased in low-, medium- and high-dose Huoluo Xiaolingdan groups. Western blot analysis showed no significant decrease in the PD-L1 protein expression in tumor tissues between the Huoluo Xiaolingdan groups and the model group. ConclusionHuoluo Xiaolingdan can inhibit TNBC in mice by increasing tumor infiltration of TCF1+CD8+ stem-like T cells, enhancing CD8+ T cell activity, and regulating immune cell subgroups such as M2 macrophages and Treg cells to enhance anti-tumor immunity. This study provides a theoretical basis for the clinical application of Huoluo Xiaolingdan in breast cancer treatment and combination therapy.

This study aims to investigate the effects of astragalus polysaccharide (APS) on diabetic retinopathy through the SHH-Gli1-AQP1 pathway. The anti-type 2 diabetes mellitus (T2DM) targets of APS were identified through comprehensive searches of drug and disease-related databases. A protein-protein interaction network was then constructed, followed by GO and KEGG enrichment analyses.Molecular docking simulations were performed to evaluate the interactions of APS and metformin with Gli1 and AQP1. An in vivo T2DM rat model was established via streptozotocin (STZ) injection and treated with metformin and varying doses of APS for 12 weeks. Histological changes in retinal cells were assessed using H&E and PAS staining. The expression levels of AQP1, Gli1, and SHH in the retina were measured using immunohistochemistry, Western blotting, immunofluorescence, and ELISA. Additionally, mRNA expression of AQP1, Gli1, and SHH was quantified by RT-qPCR. Bioinformatic analyses indicated that Gli1 and AQP1, key components of the SHH-Gli1-AQP1 signaling pathway, may be associated with T2DM. Subsequent experiments demonstrated that the STZ-induced T2DM rats exhibited significant retinal damage, which was notably mitigated by both APS and metformin treatments. Furthermore, the SHH-Gli1-AQP1 signaling pathway was found to be overactivated in STZ-induced T2DM rats. Treatment with APS and metformin significantly reduced the elevated expression levels of SHH, Gli1, and AQP1. APS effectively inhibits retinal damage of STZinduced T2DM rats by restraining the SHH-Gli1-AQP1 signaling pathway.

BACKGROUND:Some studies have shown that the hounsfield units(HU)value based on lumbar CT can be used to screen osteoporosis.At present,the number of patients with pulmonary infection has increased;the number of patients with pulmonary infection and type 2 diabetes is also increasing,which increases the utilization rate of chest CT. OBJECTIVE:To investigate the role of lumbar 1 vertebral body HU value based on chest CT in the screening of type 2 diabetes mellitus osteoporosis. METHODS:The clinical data of 244 patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Chengdu Medical College from June 2020 to June 2022 were analyzed retrospectively.The bone mineral density was obtained by dual-energy X-ray absorptiometry.According to WHO's diagnostic criteria for osteoporosis,the subjects were divided into the non-osteoporosis group(n=120)and the osteoporosis group(n=124).The general condition,T value and HU value of lumbar 1 vertebra in chest CT were compared,and the relationship between the HU value and T value of each position was analyzed and the accuracy of type 2 diabetes mellitus osteoporosis was evaluated. RESULTS AND CONCLUSION:(1)There was no significant difference in sex,age,body mass index,glycosylated hemoglobin,mean blood glucose,calcium(Ca),phosphorus(P),time of type 2 diabetes mellitus,history of hypertension and history of hyperlipidemia between the two groups(P>0.05).(2)The HU value was positively correlated with the lowest T value of the hip(r=0.619,P<0.01);the HU value was positively correlated with the hip T value(r=0.584,P<0.01),and the HU value was positively correlated with the femoral neck T value(r=0.641,P<0.01).When the HU value was 98,the prediction of type 2 diabetes mellitus osteoporosis had good accuracy,and the sensitivity was 70.8%.(3)It is concluded that the HU value of the lumbar 1 vertebra based on chest CT examination is of good value for osteoporosis screening in patients with type 2 diabetes mellitus,and may be an opportunistic and cost-free supplementary screening method for type 2 diabetes mellitus osteoporosis.

BACKGROUND:The development of steroid-induced osteonecrosis of the femoral head is a complex process involving multiple mechanisms.There is still no standard therapeutic drug for early intervention of this disease.Current studies have shown that baicalein has various pharmacological activities such as regulating lipid metabolism,bone metabolism,apoptosis and anti-oxidative stress,which provides an idea for the prevention and treatment of steroid-induced osteonecrosis of the femoral head. OBJECTIVE:To observe the preventive effect of baicalein against steroid-induced osteonecrosis of the femoral head and to investigate its possible mechanism. METHODS:Thirty-six 10-week-old male Sprague-Dawley rats were randomly divided into three groups(n=12 per group):blank control group,model group,and baicalein intervention group.In the model group and baicalein intervention group,intraperitoneal lipopolysaccharide and intramuscular injection of methylprednisolone sodium succinate were performed for modeling,while normal saline was used as a substitute for the modeling drug in the blank control group.Baicalein 300 mg/kg was administered by gavage(once a day for 6 weeks)at the time of initial intramuscular glucocorticoid injection in the baicalein intervention group,and baicalein was replaced by normal saline in the other two groups.The serum level of malondialdehyde in rats was detected at 2 weeks of the experiment.Blood lipid indicators and bone formation metabolic markers were detected at 6 weeks of the experiment,the histomorphometric changes of the femoral head were analyzed by hematoxylin-eosin staining,anti-tartaric acid phosphatase staining and TUNEL staining,and the femoral head was subjected to Micro-CT scanning and three-dimensional reconstruction of the bone in order to analyze the alterations of bone tissue structure and parameters. RESULTS AND CONCLUSION:The serum levels of malondialdehyde,triglyceride,β-collagen type Ⅰ carboxy-terminal peptide were increased and the serum levels of bone specific alkaline phosphatase and pre-collagen type Ⅰ amino-terminal peptide were decreased in the model group compared with the blank control group(P<0.05).The serum level of malondialdehyde decreased in the baicalein intervention group compared with the model group(P<0.05),but there was no significant difference between the baicalein intervention group and blank control group(P>0.05).The serum level of triglyceride was higher in the baicalein intervention group than the blank control group(P<0.05),but had no significant difference between the baicalein intervention group and model group(P>0.05).There were also no significant differences in the levels of bone specific alkaline phosphatase and β-collagen type Ⅰ carboxy-terminal peptide between the baicalein intervention group and the other two groups(P>0.05).The serum level of the baicalein intervention group was lower in the baicalein intervention group than the blank control group(P<0.05)but had no significant difference between the baicalein intervention group and model group(P>0.05).Histomorphological analysis of the femoral head showed that the rate of bone empty lacuna,osteoclast counting and cell apoptosis rate in the femoral head of model group rats were significantly higher than those of the other two groups(P<0.05).There was a significant increase in the number of adipocytes in the bone marrow cavity of the femoral head,bone trabeculae were thinned and sparsely arranged with more disruptions in the continuity.The incidence of osteonecrosis was higher in the model group(75%)than in the baicalein intervention group(25%;bilateral and unilateral exact significance results were both 0.05).There was also an increase in the number of adipocytes in the bone marrow cavity of the femoral head in the baicalein intervention group,and the trabecular changes were roughly similar to those in the model group.Micro-CT results showed that bone volume fraction,trabecular thickness,trabecular number,and bone mineral density decreased and trabecular separation increased in the model group compared with the blank control group(P<0.05).Overall significant bone mass loss was observed in the model group.Bone tissue parameters in the baicalein intervention group were significantly improved than those in the model group,which were reflected in bone volume fraction,trabecular thickness and trabecular separation(P<0.05),and trabecular number and bone mineral density had no significant difference between the baicalein intervention group and blank control group(P>0.05).Although baicalein failed to significantly ameliorate dyslipidemia and promote bone formation in rats with steroid-induced osteonecrosis of the femoral head,it could reduce the incidence of steroid-induced osteonecrosis of the femoral head by reducing oxidative stress damage,decreasing cell apoptosis,inhibiting osteoclasts,suggesting its effectiveness in the early prevention of steroid-induced osteonecrosis of the femoral head.
