OBJECTIVE To comprehensively evaluate the quality of Sanzi powder from different batches based on 12 components quantitative analysis combined with chemical pattern recognition and entropy weight-TOPSIS method. METHODS The contents of 12 components in 15 batches of Sanzi powder （No. S1-S15） were determined by HPLC-MS/MS， such as ethyl gallate， gallic acid， ferulic acid， corilagin， genipin-1-O-β-D-gentiobioside， toosendanin， geniposide， caffeic acid， methyl deacetylated coumarinate， tannic acid， rutin， quercetin. Cluster analysis （CA）， principal component analysis （PCA）， and orthogonal partial least squares-discriminant analysis （OPLS-DA） were conducted on the assay results. Using variable importance projection （VIP） value＞1 and P＜0.05 as the evaluation criteria， the quality differential markers in Sanzi powder were screened. The entropy weight method was used to calculate the weight value， and TOPSIS method was used to rank the quality of 15 batches of Sanzi powder from superior to inferior. RESULTS The contents of the 12 components were 13.494-24.292， 2 069.608-3 188.100， 1.410-3.616， 1 065.030-2 630.584， 1 404.704-1 838.078， 101.640-354.268， 9 193.720-14 777.854， 1.240-5.060， 148.028-5 541.990， 4 261.422-5 607.438， 107.560- 195.512， 2.226-4.192 μg/g， respectively. The results of CA， PCA and OPLS-DA indicated that 15 batches of Sanzi powder could be clustered into two groups. Specifically， batches S3， S7， S10 and S15 were grouped into one category， and remaining batches were grouped into one category. VIP values of geniposide， quercetin， caffeic acid， and methyl deacetylated coumarinate were all greater than 1， with corresponding P-values less than 0.05. The results of the entropy weight-TOPSIS analysis revealed that methyl deacetylate exhibited the smallest information entropy and the highest weight. The relative closeness degrees of samples S3， S7， S10 and S15 ranged from 0.789 to 0.973， while the remaining samples ranged from 0.054 to 0.172. CONCLUSIONS The contents of 12 components in Sanzi powder could be determined accurately by using HPLC-MS/MS technology. Methyl deacetylated coumarinate， geniposide， quercetin and caffeic acid were identified as the quality differential markers. It was found that the overall quality of samples S3， S7， S10 and S15 were superior to that of other batches. Notably， the quality of Gardeniae Fructus decoction pieces emerges as a critical factor in ensuring the consistency of the preparation’s quality.

Objective: To investigate the status of overweight and obesity among primary and middle school students in Yuyao City, Zhejiang Province, so as to provide the basis for formulating weight management strategies for students. Methods: A census was conducted to investigate 72 primary schools and 23 middle schools students in Yuyao City in 2024, and data such as gender and age were collected through questionnaire surveys. Height and weight were measured to calculate the body mass index (BMI). Based on the BMI thresholds for different gender and age groups, overweight and obesity were determined. Results: Totally 75 082 individuals were surveyed, including 40 435 boys and 34 647 girls. Among them, 55 172 were primary school students and 19 910 were middle school students. A total of 8 677 overweight and 7 042 obese individuals were identified, with detection rates of 11.56% and 9.38%, respectively. The detection rates of overweight and obesity in boys were higher than in girls (14.01% vs. 8.69%, 11.58% vs. 6.81%, both P<0.05). The detection rate of obesity among students in rural schools was higher than students in urban schools (10.12% vs. 8.18%, P<0.05). The detection rates of overweight and obesity of students with non-local household registration were higher than students with local household registration (12.04% vs. 10.77%, 10.44% vs. 7.64%, both P<0.05). The detection rate of overweight showed an upward trend with age (P<0.05), while no significant age-related trend was observed for obesity (P>0.05). Conclusions The detection rates of overweight and obesity were notably high among primary and middle school students in Yuyao City. Boys, students in rural schools, students with non-local household registration, and older students are the key population.

Microbial communities such as those residing in the human gut are highly diverse and complex, and many with important implications for health and diseases. The effects and functions of these microbial communities are determined not only by their species compositions and diversities but also by the dynamic intra- and inter-cellular states at the transcriptional level. Powerful and scalable technologies capable of acquiring single-microbe-resolution RNA sequencing information in order to achieve a comprehensive understanding of complex microbial communities together with their hosts are therefore utterly needed. Here we report the development and utilization of a droplet-based smRNA-seq (single-microbe RNA sequencing) method capable of identifying large species varieties in human samples, which we name smRandom-seq2. Together with a triple-module computational pipeline designed for the bacteria and bacteriophage sequencing data by smRandom-seq2 in four human gut samples, we established a single-cell level bacterial transcriptional landscape of human gut microbiome, which included 29,742 single microbes and 329 unique species. Distinct adaptive response states among species in Prevotella and Roseburia genera and intrinsic adaptive strategy heterogeneity in Phascolarctobacterium succinatutens were uncovered. Additionally, we identified hundreds of novel host-phage transcriptional activity associations in the human gut microbiome. Our results indicated that smRandom-seq2 is a high-throughput and high-resolution smRNA-seq technique that is highly adaptable to complex microbial communities in real-world situations and promises new perspectives in the understanding of human microbiomes.

Obesity and metabolic dysfunction-associated steatotic liver disease (MASLD) are linked to numerous chronic conditions, including cardiovascular disease, atherosclerosis, chronic kidney disease, and type II diabetes. Previous research identified the natural flavonoid diosmin, derived from Chrysanthemum morifolium, as a regulator of glucose metabolism. However, its effects on lipid metabolism and underlying mechanisms remained unexplored. The AMP-activated protein kinase (AMPK) pathway serves a critical function in glucose and lipid metabolism. The relationship between diosmin and the AMPK pathway has not been previously documented. This investigation examined diosmin's capacity to reduce lipid content through AMPK pathway activation in hepatoblastoma cell line G2 (HepG2) and 3T3-L1 cells. The study revealed that diosmin inhibits lipogenesis, indicating its potential as an anti-obesity agent in obese mice. Moreover, diosmin demonstrated effective MASLD alleviation in vivo. These findings suggest that diosmin may represent a promising therapeutic candidate for treating obesity and MASLD.

OBJECTIVE To explore the potential of Aconiti Kusnezoffii Radix in affecting diabetes mellitus type 2(T2DM) and the potential mechanism for T2DM related symptoms based on systematic pharmacology, bioinformatics, molecular docking and in vitro and in vivo experiments. METHODS The database was used to search the related chemical components of Aconiti Kusnezoffii Radix, predict the potential targets and intervene related diseases. The differential genes of T2DM relative healthy people were retrieved from GEO database, mapped with the action target of Aconiti Kusnezoffii Radix, and placed in DAVID database for biological function enrichment. The sensitivity of the target gene to T2DM was analyzed by one-way ANOVA, binary logistic regression analysis and ROC curve. The binding position and interaction force between chemical compounds of Aconiti Kusnezoffii Radix and target proteins were analyzed by molecular docking technology. The effect of Aconiti Kusnezoffii Radix and its chemical compounds on the expression of target protein was verified by T2DM model in vivo and in vitro. RESULTS Through database retrieval and analysis, 304 kinds of target related diseases(P value<0.05, FDR<0.05) were obtained, and T2DM with the highest degree value(Degree=59) was selected and analyzed. The 43 target genes were obtained from the intersection of differential genes in T2DM relatively healthy people and potential action targets of Aconiti Kusnezoffii Radix. A total of 9 genes with significant differences were obtained by one-way ANOVA, 5 meaningful genes were obtained by binary logistic regression analysis, and 3 genes with area under ROC curve AUC>0.5 were obtained. By molecular docking (+)-Isoboldine binds to proteins APEX1, CASP1 and CBFB, Napelline binds to proteins CBX1 and EHMT2 through different forces such as hydrogen bond interaction, ligand interaction, hydrophobic interaction, ionizability and electrostatic interaction, so as to increase the ability of ligands to target proteins. After 2 weeks of treatment with Aconiti Kusnezoffii Radix aqueous extract, Aconiti Kusnezoffii Radix may alleviated the symptoms of T2DM by improving peripheral neuropathy. Moreover, Aconiti Kusnezoffii Radix could affect the protein expression of APEX1, CASP1, CBFB, CBX1 and EHMT2 in rat liver tissue. The effect of (+)-Isoboldine and Napelline chemical compounds in Aconiti Kusnezoffii Radix on the target protein of the model in vitro was consistent with that in vivo. CONCLUSION It is preliminarily revealed that Aconiti Kusnezoffii Radix can be used as a potential therapeutic drug to improve T2DM peripheral neuropathy, which lays a theoretical foundation for the research and development of Chinese Mongolian medicine and the excavation of new target drugs for the treatment of T2DM.

Objective To investigate the mechanism of sanguinarine(SA)for alleviating ulcerative colitis(UC)induced by dextran sodium sulfate(DSS)in mice.Methods Male C57BL/6 mouse models of 3.5%DSS-induced UC were randomized for treatment with 1,5 and 10 mg/kg SA by gavage,400 mg/kg sulfasalazine by gavage,or 10 mg/kg SA combined with intraperitoneal injection of 30 mg/kg ML385(a Nrf2 inhibitor).The changes in intestinal inflammation was assessed by monitoring weight changes,disease activity index(DAI)score,colon length measurement,and HE staining.After the treatments,the colon tissues were collected for detection of malondialdehyde(MDA)content using colorimetry,mRNA expressions of inflammatory factors using RT-qPCR,and the expressions of Nrf2,HO-1,Keap-1,p-p65,p65,occludin,and ZO-1 proteins were detected using Western blotting.Results SA treatment obviously alleviated weight loss,colon length shortening and DAI score increase and ameliorated structural destruction of the colon glands and colonic crypts in mice with DSS-induced UC.SA intervention significantly decreased the levels of TNF-α,IL-1β and IL-6 mRNA and lowered ROS and MDA levels in the colon tissue of UC mice.The mouse models receiving SA treatment showed significantly increased expressions of Nrf2,HO-1,occludin and ZO-1 and lowered expressions of Keap-1 and P-P65 in the colon tissue without significant changes of p65 expression,and these changes were SA dose-dependent.Treatment with ML385 obviously attenuated the effect of high-dose SA for improving UC in the mouse models.Conclusion SA can improve UC-like enteritis in mice possibly by activating the Nrf2 pathway and inhibiting the NF-κB pathway in the colon tissue.

Background::Liver cancer remains the sixth most commonly diagnosed cancer and the third leading cause of cancer-related deaths worldwide, causing a heavy burden globally. An updated assessment of the global epidemiology of the liver cancer burden that addresses geographical disparities is necessary to better understand and promote healthcare delivery.Methods::Data were extracted from the GLOBOCAN 2022 database, including the number, crude, and age-standardized rates of incidence and mortality at the global, country, continent, and human development index (HDI) regional levels. Age-standardized rates (incidence and mortality) per 100,000 person-years were adjusted based on the Segi-Doll World standard population. The mortality-to-incidence ratios (MIR) for each region and country were calculated. The HDI and gross national income (GNI) for 2022 were obtained, and a Pearson correlation analysis was conducted with the incidence, mortality, and MIR.Results::In 2022, approximately 866,136 new liver cancer cases and 758,725 related deaths were recorded worldwide, with a global MIR of 0.86. Males had a disproportionately higher burden than females across all levels, and the highest burden was observed in the elderly population. Geographically, the regions with the highest incidence rates included Micronesia, Eastern Asia, and Northern Africa, and the regions with the highest mortality rates included Northern Africa, Southeastern Asia, Eastern Asia, and Micronesia. Notably, Mongolia had a strikingly high burden compared to other countries. The highest MIR was observed in North America and the lowest in Africa. Negative associations of HDI and GNI with liver cancer mortality and MIR were identified, irrespective of sex.Conclusions::The current liver cancer burden underscores the presence of remarkable geographic heterogeneity, which is particularly evident across countries with varying HDI levels, highlighting the urgent need to prioritize health accessibility and availability to achieve health inequities.

Dental pulp stem cells(DPSCs)are a type of mesenchymal stem cells with broad application potential.Due to their multipotent differentiation capabilities and ease of access,DPSCs have become a focus of research in the field of ophthalmology.In recent years,DPSCs have shown the potential clinical applications in the treatment of corneal epithelial injuries and retinal degenerative diseases.DPSCs can promote the corneal epithelial regeneration and reconstruction by differentiating into the corneal epithelial cells and inhibiting the M1 macrophages.Additionally,DPSCs can differentiate into the retinal photoreceptor-like cells and retinal ganglion-like cells,replace original retinal neurons,secrete neurotrophic factors to mediate injury repair,promote retinal regeneration,and improve the original function of the retina.This article systematically reviews the relevant domestic and international literatures in recent years,discussing the biological characteristics of DPSCs and the research progress in their applieation in the treatment of corneal and retinal diseases,with the aim of providing insights and strategies for the study of DPSCs in translational medicine and ophthalmic-related diseases.

Objective The study aimed to explore the main forms of double minute chromosomes(DMs)in the cell cycle of colorectal cancer at different phases,and to clarify the replication and separation phases of DMs.Methods After using serum-free starvation to block the progression of cell cycle in colorectal cancer COLO 320DM cells,Calyculin-A was used to induce interphase cells to prepare karyotype samples through advanced chromatin condensation.COLO 320DM cells were treated with colchicine to ob-tain mitosis(M)phase cells for karyotype analysis.The karyotypes of cells at the early stage of DNA synthesis(G1 phase),the late stage of DNA synthesis(G2 phase),metaphase(M-mid),anaphase(M-late),and telophase(M-ter)of mitosis were observed and photographed under a regular optical microscope,and counted the number of DMs.Results DMs mainly existed in monotypic form at the G1 phase,M-late phase and M-ter phase of cells.In the G2 and M-mid phases of cells,DMs mainly existed in a diploid form.Conclusion Monomeric DMs undergo replication in the S phase and transform from monomers to diploids,while diploid DMs in the M-late phase complete separation and transition from diploids to monomers.
