ObjectiveTo observe the effect of Huayu Mingmu prescription on retinal angiogenesis and phosphatidylinositol 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/Akt/mTOR)-hypoxia inducible factor-1α/vascular endothelial growth factor A (HIF-1α/VEGFA) signaling pathway in diabetic retinopathy (DR) rats. MethodsSixty-four SPF-grade male SD rats were used in the study. Eleven rats were randomly selected as the normal group, while the remaining 53 rats were fed a high-sugar, high-fat diet combined with low-dose streptozotocin (STZ) intraperitoneal injection to establish a type 2 diabetes mellitus (T2DM) rat model. DR model evaluation was performed after 12 weeks of diabetes. The rats were then divided into model, low-dose, medium-dose, and high-dose groups of Huayu Mingmu prescription (9.29, 18.57, 37.14 g·kg-1), and a calcium dobesilate group (0.16 g·kg-1), with 10 rats in each group. The rats were orally administered the corresponding doses of Huayu Mingmu prescription and calcium dobesilate. The normal and model groups received equal volumes of physiological saline via gavage for 8 consecutive weeks. Retinal vascular changes were observed through fundus photography, and pathological changes in retinal tissue were evaluated using hematoxylin-eosin (HE) staining. Retinal microvascular pathological changes were examined through retinal vascular network preparation and periodic acid-Schiff (PAS) staining. Immunofluorescence (IF) was used to detect the expression of VEGFA and angiopoietin-2 (Ang-2) in retinal tissue. Western blot was employed to detect the protein expression of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue. Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) was used to assess the mRNA expression of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue. ResultsCompared with the normal group, the model group exhibited significant pathological changes in retinal tissue, including the appearance of acellular capillaries, as well as significant endothelial cell (E) proliferation and pericyte (P) loss (P<0.01). The E/P was significantly elevated (P<0.01). Protein and mRNA expression levels of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue were significantly increased (P<0.01), and the expression of Ang-2 protein was significantly elevated (P<0.01). In contrast, retinal tissue in the treatment groups showed alleviated pathological changes, with reduced endothelial cell proliferation and pericyte loss (P<0.05, P<0.01). Among the treatment groups, the high-dose Huayu Mingmu prescription and the calcium dobesilate group exhibited a decreased E/P (P<0.01). Protein and mRNA expression levels of PI3K, Akt, mTOR, HIF-1α, VEGFA, and VEGFR2 in retinal tissue were significantly reduced (P<0.05, P<0.01), and the expression of Ang-2 protein was significantly decreased (P<0.01). ConclusionHuayu Mingmu prescription can intervene in retinal neovascularization in DR rats, delay the progression of DR, and its mechanism may be related to antagonizing the PI3K/Akt/mTOR-HIF-1α/VEGFA signaling pathway.

OBJECTIVE To evaluate the long-term cost-effectiveness of canagliflozin or semaglutide in patients with type 2 diabetes mellitus(T2DM)poorly controlled with metformin. METHODS Based on the perspective of China’s health system, a Markov model was used to calculate the long-term costs and utilities of canagliflozin or semaglutide combined with metformin for T2DM patients in China for 30 years based on the data from SUSTAIN 8 study. The incremental cost-effectiveness ratio(ICER) and incremental net monetary benefit (INMB) were calculated using one time the 2024 per capita gross domestic product(GDP) as the willingness-to-pay(WTP) threshold. One-way sensitivity analysis, probability sensitivity analysis and scenario analysis were conducted to confirm the stability of the conclusions. RESULTS Compared with canagliflozin + metformin, ICER of semaglutide combined with metformin was 260 485.67 yuan/quality-adjusted life year (QALY),which was higher than the WTP threshold set in this study (95 749 yuan/QALY),and the corresponding INMB was -61 576.24 yuan,indicating that the canagliflozin + metformin regimen was more cost-effective. The cost of diabetes without complications treatment in the semaglutide + metformin group had the greatest influence on INMB,but changes in parameters within the selected range did not drive decision reversal. With the increasing of WTP threshold,the economic acceptability of semaglutide + metformin regimen increased. Under the current WTP threshold,the annual cost of semaglutide should be reduced by 42.95% to make the semaglutide + metformin regimen more cost- effective. CONCLUSIONS From the perspective of China’s health system, canagliflozin + metformin is more cost-effective than semaglutide + metformin for T2DM patients yueru. with poor glycemic control with metformin alone.

Modulating Tankyrases (TNKS), interactions with USP25 to promote TNKS degradation, rather than inhibiting their enzymatic activities, is emerging as an alternative/specific approach to inhibit the Wnt/β-catenin pathway. Here, we identified UAT-B, a novel neoantimycin analog isolated from Streptomyces conglobatus, as a small-molecule inhibitor of TNKS-USP25 protein-protein interaction (PPI) to overcome multi-drug resistance in colorectal cancer (CRC). The disruption of TNKS-USP25 complex formation by UAT-B led to a significant decrease in TNKS levels, triggering cell apoptosis through modulation of the Wnt/β-catenin pathway. Importantly, UAT-B successfully inhibited the CRC cells growth that harbored high TNKS levels, as demonstrated in various in vitro and in vivo studies utilizing cell line-based and patient-derived xenografts, as well as APCmin/+ spontaneous CRC models. Collectively, these findings suggest that targeting the TNKS-USP25 PPI using a small-molecule inhibitor represents a compelling therapeutic strategy for CRC treatment, and UAT-B emerges as a promising candidate for further preclinical and clinical investigations.

Objective:
To systematically evaluate the incidence and influencing factors of depression in family caregivers of Alzheimer's disease (AD) patients, so as to provide the basis for the prevention and treatment of depression among the family caregivers of AD patients.
Methods:
Publications pertaining to depression in family caregivers of AD patients were retrieved from CNKI, Wanfang Data, PubMed and other databases from the time of their establishment to June 15, 2023. The evaluation criteria recommended by the Agency for Healthcare Research and Quality (AHRQ) and the Newcastle-Ottawa Scale were used to assess the quality of cross-sectional and cohort studies, respectively. Stata 16.0 and Revman 5.4 softwares were used to conduct a meta-analysis on the incidence and influencing factors of depression in family caregivers of AD patients. Sensitivity analysis and publication bias assessment were also performed on the results.
Results:
A total of 2 324 articles were retrieved, and ultimately 14 articles were included, with a total sample size of 8 313 individuals. There were 6 high-quality articles and 8 moderate-quality articles. Meta-analysis showed that the incidence of depression in family caregivers of AD patients was 37.5% (95%CI: 30.2%-45.1%). Factors associated with depression included patients' high degree of dementia (OR=1.718, 95%CI: 1.059-2.789), patients' low scores on Activities of Daily Living Scale (OR=1.344, 95%CI: 1.059-1.706), patients' psychobehavioral abnormalities (OR=1.248, 95%CI: 1.155-1.348), long duration of caregiving (OR=1.998, 95%CI: 1.637-2.437), less involvement of other family members in caregiving (OR=1.597, 95%CI: 1.237-2.061), low educational level (OR=1.191, 95%CI: 1.044-1.359), poor caregiving skills (OR=3.060, 95%CI: 2.257-4.149), poor self-rated health (OR=2.536, 95%CI: 1.114-5.771) and social support (OR=0.424, 95%CI: 0.232-0.774). The results of depression incidence demonstrated good stability with no significant publication bias. However, publication bias was observed in the influencing factors for depression, which were patients' high degree of dementia and patients' low scores on Activities of Daily Living Scale.
Conclusions
The incidence of depression in family caregivers of AD patients ranges from 30.2% to 45.1%. It is primarily influenced by the severity of patients' symptoms and ability to perform daily activities, and caregivers' educational level, caregiving skills, health status, caregiving duration and social support.

Objective:To evaluate the efficacy and safety of endoscopic submucosal dissection (ESD) for circular superficial esophageal cancer.Methods:A retrospective analysis was conducted on 74 consecutive cases of circular superficial esophageal squamous cell carcinoma treated with ESD at Nanjing Drum Tower Hospital from January 2015 to December 2019. The success rate of ESD, curative resection rate, incidence of complications, and additional treatment were mainly observed.Results:One case was transferred to surgery, and the remaining 73 cases successfully completed ESD treatment. The success rate of ESD was 98.6%. Postoperative pathology of ESD revealed that 39 cases achieved curative resection, with a curative resection rate of 53.4% (39/73). Intraoperative muscle layer injury occurred in 15 cases (20.5%), and intraoperative perforation occurred in 1 case (1.4%). Two cases (2.7%) experienced delayed bleeding, and one case (1.4%) experienced delayed perforation. Eleven cases were lost to follow-up, and the remaining 62 cases received follow-up for 36.4±19.0 months. Among the follow-up cases, 12 underwent additional surgery and 5 cases additional chemotherapy and radiotherapy. Among the 57 patients with follow-up data who did not underwent surgery, 49 developed esophageal stenosis after ESD, with an incidence rate of 86.0%.Conclusion:ESD for circular superficial esophageal cancer is generally safe, but it is prone to muscle layer injury during the operation, with a low curative resection rate, a high incidence of postoperative esophageal stenosis, and a high proportion of additional surgical procedures.
