ObjectiveTo explore the mechanism of Shaoyaotang in the prevention and treatment of colitis-associated carcinogenesis (CAC) based on myeloid-derived suppressor cells (MDSCs)-related immunosuppressive microenvironment. MethodsA total of 140 six-week-old SPF FVB male mice were randomly divided into seven groups: Blank group, Shaoyaotang without model group (7.12 g·kg-1), model group, sulfasalazine group (0.52 g·kg-1), Shaoyaotang low-dose group (3.56 g·kg-1), Shaoyaotang medium-dose group (7.12 g·kg-1) and Shaoyaotang high-dose group (14.24 g·kg-1), with 20 mice in each group. The blank control group and the Shaoyaotang without model group received a single intraperitoneal injection of physiological saline (10 mg·kg-1), while the other five groups were given a single intraperitoneal injection of azoxymethane (AOM) (10 mg·kg-1). After 1 week, the mice were given drinking water containing 2% dextran sulfate sodium (DSS) for 1 week, followed by normal drinking water for 2 weeks. This cycle was repeated three times over a total period of 14 weeks to establish the CAC mouse model. Each group was administered gavage once daily for 2 weeks starting on the 14th day of the experiment, followed by three times a week until the end of the experiment. The body weight of the mice was recorded weekly. Mice were sacrificed on the 28th and 98th days of the experiment. After dissection, the colon length, colon weight, spleen weight, tumor size, and tumor number were measured. Hematoxylin and eosin (HE) staining was used to assess the pathological morphology of colon tumor tissue. Flow cytometry was used to detect MDSCs, regulatory T cells (Tregs), CD4+ T cells, CD8+ T cells, and the CD4+/CD8+ T cell ratio in the spleen. Immunohistochemistry was used to detect the expression levels of programmed cell death protein-1 (PD-1), programmed cell death ligand 1 (PD-L1), phosphorylated AMP-activated protein kinase (p-AMPK), phosphorylated nuclear factor-κB (p-NF-κB), and hypoxia-inducible factor 1α (HIF-1α) in the colon tissue. ResultsOn day 14, compared with the blank group, the body weight of the model group was significantly reduced (P<0.01), reaching its lowest point on day 28 (23.39 ± 0.95 ) g. On days 28 and 98, compared with the blank group, the colon length in the model group was significantly shortened (P<0.01), the colon index significantly increased (P<0.01), the spleen index significantly increased (P<0.01), and the tumor load significantly increased (P<0.01). HE staining showed that in the model group, tumor cells, a large number of inflammatory cell infiltrates, goblet cell disappearance, and crypt loss were observed. In each dose group of Shaoyaotang, the damage to the colonic mucosa, inflammatory cell infiltration, and crypt structure destruction were alleviated. Compared with the model group, the body weight of mice in each dose group of Shaoyaotang increased. On day 98, the colon length was significantly increased (P<0.01), the colon index significantly decreased (P<0.01), the spleen index significantly decreased (P<0.01), and the tumor burden significantly decreased (P<0.01) in each Shaoyaotang dose group. On days 28 and 98, MDSCs and Tregs in the spleen of the medium- and high-dose Shaoyaotang groups were significantly reduced (P<0.01), while CD4+ T cells and the CD4+/CD8+ T cell ratio were significantly increased (P<0.01). The proportion of CD8+ T cells in the spleen and the expression levels of PD-1 and PD-L1 in the colon tissues of mice in each Shaoyaotang dose group were significantly increased to varying degrees (P<0.05, P<0.01). On days 28 and 98, the expression of p-AMPK-positive cells in the colon tissue of the medium- and high-dose Shaoyaotang groups was significantly increased (P<0.01), while the expression of p-NF-κB and HIF-1α was significantly reduced (P<0.01). ConclusionShaoyaotang can regulate MDSC recruitment and modulate the immune function of T lymphocyte subsets to inhibit the occurrence and development of AOM/DSS-induced CAC in mice. The mechanism may be related to the activation of the AMPK/NF-κB/HIF-1α pathway.

ObjectivePatients with hepatic glycogen storage disease(GSD)have recurrent episodes of hypoglycemia. This study aimed to investigate and analyze blood glucose and biochemical indicators in pediatric patients with hepatic GSD, thus provide data support for hypoglycemia prevention and its clinical management. MethodsA cross-sectional field study was conducted among patients with hepatic GSD treated in the Department of Pediatrics of Guangdong Provincial People's Hospital on July 14, 2024. We collected the peripheral blood samples of the patients and their healthy family controls on site, then analyzed and compared their blood glucose and biochemical indicators. ResultsOf the 44 patients with hepatic GSD, there were 34 males and 10 females, including GSD Ib(n =14), GSD Ia(n=15), GSD Ⅲ(n=2), GSD Ⅵ(n=7)and GSD Ⅸ(n=6). The average age was 7.60(5.08-11.98)years. All patients were on uncooked cornstarch(UCCS)therapy. Of the patients, 77.3%(34/44)had hepatomegaly, 61.4%(27/44)had recurrent hypoglycemia, 61.4%(27/44)had blood glucose ≤ 3.9 mmol/L, 18.2%(8/44)had blood glucose ≤ 2.8 mmol/L, and none of the 8 cases was GSD Ib. The lowest blood glucose level was 1.19 mmol/L and no episodes of hypoglycemia occurred. Of the family control subjects, 65.9%(29/44)had blood glucose ≤ 3.9 mmol/L. There was no significant difference in hypoglycemia prevalence between hepatic GSD group and control group(P=0.658). The hepatic GSD patients had hyperlactacemia, hyperuricemia and hypercholesterolemia prevalence rates of 65.9%, 45.5% and 9.1%, respectively, as compared with 18.2%, 43.2% and 15.9%, respectively, for the family control subjects. No significant difference was found in the prevalence rates of hyperuricemia and hypercholesterolemia between the two groups(P=0.830 and P=0.334, respectively). ConclusionsAsymptomatic hypoglycemia is common in patients with hepatic GSD, especially in non-GSD-Ib patients. It is necessary to optimize the diet management of UCCS, conduct dynamic blood glucose monitoring and follow a light diet, so as to decrease hyperuricemia and hypercholesterolemia, avoid and reduce the serious adverse reactions and complications caused by severe hypoglycemia.

OBJECTIVE To understand the development status and existing problems of traditional Chinese medicine(TCM) pharmacists in public TCM hospitals in China, aiming to provide suggestions for the competent departments to formulate management policies for TCM pharmacists and promote the healthy development of TCM. METHODS The data on the number and professional titles of TCM pharmacists in public TCM hospitals in China from 2019 to 2023 were collected. Descriptive analysis was employed to analyze the number, distribution and professional titles of TCM pharmacists in public TCM hospitals across the country, and to measure the quantity shortfalls of the number of TCM pharmacists in these hospitals. RESULTS From 2019 to 2023, the number of TCM pharmacists in public TCM hospitals in China grew slowly, with an average annual growth rate of 2.56%. However, the proportion of TCM pharmacists to the total number of pharmacists in public TCM hospitals gradually decreased, with an average annual growth rate of -0.65%. In terms of hospital grades, the number of TCM pharmacists in tertiary public TCM hospitals showed positive growth, while those in secondary and primary public TCM hospitals showed negative growth. In terms of hospital types, the average annual growth rate of TCM pharmacists in TCM hospitals was 2.22%, in integrated Chinese and Western medicine hospitals it was 7.97%, and in ethnic minority medicine hospitals it was 2.74%. The development of TCM pharmacists in different provinces was uneven. The annual growth rate of TCM pharmacists in Guizhou exceeded 10%, while the growth rate in Hunan and Heilongjiang was negative. In 2023, the number of TCM pharmacists per thousand population in public TCM hospitals was 0.03, indicating a relatively low staffing level. The professional titles of TCM pharmacists in public TCM hospitals were mainly primary and E-mail:601907549@qq.com intermediate, with a total of 67.33%. According to the calculation that the proportion of TCM pharmacists to pharmacists was not less than 60%, public TCM hospitals and hospitals of integrated TCM and Western medicine should be reconfigured with TCM pharmacists 6 212 and 1 288 people, respectively. CONCLUSIONS The number of TCM pharmacists in public TCM hospitals is growing slowly, with insufficient staffing levels, relatively low professional titles, and uneven distribution and development across provinces. It is suggested that relevant competent departments strengthen policy guidance, increase the attention given by the state level to TCM pharmacists, strengthen the construction of the talent team for TCM pharmacists, improve the quality and optimize the allocation of TCM pharmacist talents in order to promote the high-quality development of TCM services.

ObjectiveTo preliminarily explore the active components and target pathways of Angelicae Sinensis Radix-Polygonati Rhizoma (ASR-PR) herb pair in the treatment of simple obesity through network pharmacology and molecular docking, and to verify and investigate its mechanism of action via animal experiments. MethodsThe chemical constituents and targets of ASR and PR were predicted using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP). Targets related to simple obesity were identified by retrieving the GeneCards, Online Mendelian Inheritance in Man (OMIM), Pharmacogenomics Knowledgebase (PharmGKB), and DisGeNET databases. The intersection of drug and disease targets was used to construct an active component-target network using Cytoscape software. This network was imported into the STRING database to construct a protein-protein interaction (PPI) network, and topological analysis was conducted to identify core genes. Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis and mapping were performed using the DAVID database and the Microbioinformatics platform. AutoDock 1.5.7 software was used to perform molecular docking between the top five active components and core targets. An animal model of simple obesity was established by feeding C57BL/6J mice a high-fat diet. The mice were administered ASR (2.06 g·kg-1), PR (2.06 g·kg-1), or ASR-PR (4.11 g·kg-1) for 10 weeks, while the model group received an equal volume of purified water by gavage. After the administration period, the mice were sacrificed to measure body fat weight and serum levels of total cholesterol (TC), triglycerides (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL). Hematoxylin-eosin (HE) staining was used to observe histopathological sections of liver and adipose tissue. Serum levels of leptin, interleukin-6 (IL-6), and tumor necrosis factor-α (TNF-α) were determined by enzyme-linked immunosorbent assay (ELISA), and the mRNA expression levels of epidermal growth factor receptor (EGFR) and signal transducer and activator of transcription 3 (STAT3) in liver tissue were detected by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsNetwork pharmacology and molecular docking results indicated that the treatment of simple obesity by ASR-PR may involve the regulation of protein expression of core targets EGFR and STAT3 by its main components MOL009760 (Siberian glycoside A_qt), MOL003889 (methyl protodioscin_qt), MOL009766 (resveratrol), MOL006331 (4′,5-dihydroxyflavone), and MOL004941 (baicalin), thereby modulating the PI3K/Akt and JAK/STAT signaling pathways. The animal experiment results showed that compared with the normal group, the model group had significantly increased body weight, body fat weight, and serum levels of TG, TC, TNF-α, IL-6, and leptin (P<0.01). EGFR mRNA expression was significantly elevated (P<0.05), while STAT3 mRNA expression was significantly decreased (P<0.01). Histological analysis revealed disordered hepatic architecture in the model group, with pronounced lipid vacuoles, cytoplasmic loosening, lipid accumulation, and steatosis. Adipocytes in white adipose tissue (WAT) and brown adipose tissue (BAT) of the model group exhibited markedly increased diameters, reduced cell counts per unit area, and irregular morphology. Compared with the model group, the ASR-PR group significantly reduced body weight, body fat weight, serum TC, IL-6, TNF-α, leptin levels, and EGFR mRNA expression (P<0.01). TG levels were also significantly decreased (P<0.05), while STAT3 mRNA expression was significantly increased (P<0.01). Histopathological improvements included reduced size and number of hepatic lipid vacuoles and restoration of liver cell morphology toward that of the normal group. The diameter of adipocytes significantly decreased, and the number of adipocytes per unit area increased. ConclusionASR-PR may regulate the expression of key target proteins such as EGFR and STAT3 via its core active components, modulate the PI3K/Akt and JAK/STAT signaling pathways, repair damaged liver and adipose tissues, and thereby alleviate the progression of obesity in mice.

BACKGROUND:Psoralen has a strong anti-osteoporotic activity and may have a restorative effect on chemotherapy-induced osteoporosis. OBJECTIVE:To explore the restorative effect of psoralen on the osteogenic differentiation of bone marrow mesenchymal stem cells in mice inhibited by cyclophosphamide and its mechanism. METHODS:C57BL/6 mouse bone marrow mesenchymal stem cells were isolated and cultured.Effect of psoralen on viability of bone marrow mesenchymal stem cells was detected by MTT assay.Osteogenic induction combined with alkaline phosphatase staining was used to determine the optimal dose of psoralen to restore the osteogenic differentiation of bone marrow mesenchymal stem cells inhibited by cyclophosphamide.The mRNA expression levels of Runx2,alkaline phosphatase,Osteocalcin,osteoprotegerin,and Wnt/β-catenin signaling pathway-related genes Wnt1,Wnt4,Wnt10b,β-catenin,and c-MYC were measured by RT-qPCR at different time points under the intervention with psoralen.The protein expression of osteogenic specific transcription factor Runx2 and Wnt/β-catenin signaling pathway related genes Active β-catenin,DKK1,c-MYC,and Cyclin D1 was determined by western blot assay at different time points under the intervention with psoralen. RESULTS AND CONCLUSION:(1)There was no significant effect of different concentrations of psoralen on the viability of bone marrow mesenchymal stem cells.The best recovery of the inhibition of osteogenic differentiation of bone marrow mesenchymal stem cells caused by cyclophosphamide was under the intervention of psoralen at a concentration of 200 μmol/L.(2)Psoralen reversed the reduction in osteogenic differentiation marker genes Runx2,alkaline phosphatase,Osteocalcin and osteoprotegerin mRNA expression and Runx2 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium.(3)Psoralen reversed the decrease in Wnt/β-catenin pathway-related genes Wnt4,β-catenin,c-MYC mRNA and Active β-catenin,c-MYC,and Cyclin D1 protein expression and the increase in DKK1 protein expression in bone marrow mesenchymal stem cells caused by cyclophosphamide conditioned medium.(4)The results showed that cyclophosphamide inhibited osteogenic differentiation of bone marrow mesenchymal stem cells in mice,and psoralen had a restorative effect on it.The best intervention effect was achieved at a concentration of 200 μmol/L psoralen,and this protective effect might be related to the activation of Wnt4/β-catenin signaling pathway by psoralen.

Background:
The genetic basis for hyperglycaemia in pregnancy remain unclear. This study aimed to uncover the genetic determinants of gestational diabetes mellitus (GDM) and investigate their applications.
Methods:
We performed a meta-analysis of genome-wide association studies (GWAS) for GDM in Chinese women (464 cases and 1,217 controls), followed by de novo replications in an independent Chinese cohort (564 cases and 572 controls) and in silico replication in European (12,332 cases and 131,109 controls) and multi-ethnic populations (5,485 cases and 347,856 controls). A polygenic risk score (PRS) was derived based on the identified variants.
Results:
Using the genome-wide scan and candidate gene approaches, we identified four susceptibility loci for GDM. These included three previously reported loci for GDM and type 2 diabetes mellitus (T2DM) at MTNR1B (rs7945617, odds ratio [OR], 1.64; 95% confidence interval [CI],1.38 to 1.96]), CDKAL1 (rs7754840, OR, 1.33; 95% CI, 1.13 to 1.58), and INS-IGF2-KCNQ1 (rs2237897, OR, 1.48; 95% CI, 1.23 to 1.79), as well as a novel genome-wide significant locus near TBR1-SLC4A10 (rs117781972, OR, 2.05; 95% CI, 1.61 to 2.62; Pmeta=7.6×10-9), which has not been previously reported in GWAS for T2DM or glycaemic traits. Moreover, we found that women with a high PRS (top quintile) had over threefold (95% CI, 2.30 to 4.09; Pmeta=3.1×10-14) and 71% (95% CI, 1.08 to 2.71; P=0.0220) higher risk for GDM and abnormal glucose tolerance post-pregnancy, respectively, compared to other individuals.
Conclusion
Our results indicate that the genetic architecture of glucose metabolism exhibits both similarities and differences between the pregnant and non-pregnant states. Integrating genetic information can facilitate identification of pregnant women at a higher risk of developing GDM or later diabetes.

Background/Aims:
Nonalcoholic fatty liver disease (NAFLD) is a common disease with severe inflammatory processes associated with numerous gastrointestinal diseases, such as inflammatory bowel disease (IBD). Therefore, we investigated the relationship between NAFLD and IBD and the possible risk factors associated with the diagnosis of IBD.
Methods:
This longitudinal nationwide cohort study investigated the risk of IBD in patients with NAFLD alone. General characteristics, comorbidities, and incidence of IBD were also compared.
Results:
Patients diagnosed with NAFLD had a significant risk of developing IBD compared to control individuals, who were associated with a 2.245-fold risk of the diagnosis of IBD and a 2.260- and 2.231-fold of increased diagnosis of ulcerative colitis and Crohn’s disease, respectively (P< 0.001). The cumulative risk of IBD increased annually during the follow-up of patients with NAFLD (P< 0.001).
Conclusions
Our results emphasize that NAFLD significantly impacts its incidence in patients with NAFLD. If patients with NAFLD present with risk factors, such as diabetes mellitus and dyslipidemia, these conditions should be properly treated with regular follow-ups. Furthermore, we believe that these causes may be associated with the second peak of IBD.

Purpose:
Cancer has become a significant major public health concern, making the discovery of new cancer markers or therapeutic targets exceptionally important. Elevated expression of tumor necrosis factor receptor superfamily member 12A (TNFRSF12A) expression has been observed in certain types of cancer. This project aims to investigate the function of TNFRSF12A in tumors and the underlying mechanisms.
Materials and Methods:
Various websites were utilized for conducting the bioinformatics analysis. Tumor cell lines with stable knockdown or overexpression of TNFRSF12A were established for cell phenotyping experiments and subcutaneous tumorigenesis in BALB/c mice. RNA-seq was employed to investigate the mechanism of TNFRSF12A.
Results:
TNFRSF12A was upregulated in the majority of cancers and associated with a poor prognosis. Knockdown TNFRSF12A hindered the colorectal cancer progression, while overexpression facilitated malignancy both in vitro and in vivo. TNFRSF12A overexpression led to increased nuclear factor кB (NF-κB) signaling and significant upregulation of baculoviral IAP repeat containing 3 (BIRC3), a transcription target of the NF-κB member RELA, and it was experimentally confirmed to be a critical downstream factor of TNFRSF12A. Therefore, we speculated the existence of a TNFRSF12A/RELA/BIRC3 regulatory axis in colorectal cancer.
Conclusion
TNFRSF12A is upregulated in various cancer types and associated with a poor prognosis. In colorectal cancer, elevated TNFRSF12A expression promotes tumor growth, potentially through the TNFRSF12A/RELA/BIRC3 regulatory axis.
