ObjectiveTo investigate the effects of different concentrations of Shaoyaotang-containing serum on lipopolysaccharide (LPS)-induced inflammation of human colorectal adenocarcinoma (Caco-2) cells by inhibiting apoptosis via activating the tumor necrosis factor (TNF) receptor superfamily member 6 (Fas)/Fas ligand (FasL) pathway. MethodsCaco-2 cells were allocated into blank, model (LPS, 10 mg·L-1), Shaoyaotang-containing serum (5%, 10%, 15%, 20%), and Fas inhibitor (KR-33493, 20 mmol·L-1) groups. Except the blank group, the other groups were stimulated with 10 mg·L-1 LPS for 24 h for the modeling of inflammation. After successful modeling, the blank, Fas inhibitor, and model groups were treated with blank serum, and the Shaoyaotang-containing serum groups were treated with the serum samples at corresponding concentrations for 24 h. The Fas inhibitor group was subjected to KR-33493 pretreatment for 1 h. Cell proliferation and viability were examined by the cell-counting kit-8 (CCK-8) method. The levels of interleukin (IL)-6, IL-1β, and TNF-α were measured by enzyme-linked immunosorbent assay. Apoptosis was detected by flow cytometry. The protein and mRNA levels of Fas, FasL, cysteinyl aspartate-specific proteinase (Caspase)-3, Caspase-9, B-cell lymphoma 2 (Bcl-2), and Bcl-2-associated X protein (Bax) were determined by Western blot and Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR), respectively. ResultsCompared with the blank group, the model group presented a decrease in cell survival rate (P<0.01). Compared with that in the model group, the cell survival rate showed no significant change in the 5% Shaoyaotang-containing serum group but increased in the 10%, 15%, and 20% Shaoyaotang-containing serum groups (P<0.01). Since there was no statistical difference between the 5% Shaoyaotang-containing serum group and the model group, 10%, 15%, and 20% Shaoyaotang-containing sera were selected for the follow-up study. Compared with the blank group, the model group showed risen levels of IL-6, IL-1β, and TNF-α (P<0.01), an increased apoptosis rate (P<0.01), up-regulated protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.01), and down-regulated protein and mRNA levels of Bcl-2 (P<0.01). Compared with the model group, the Fas inhibitor group and the 10%, 15%, and 20% Shaoyaotang-containing serum groups showed declined levels of IL-6, IL-1β, and TNF-α (P<0.01), decreased apoptosis rates (P<0.01), down-regulated protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.05, P<0.01), and up-regulated protein and mRNA levels of Bcl-2 (P<0.05, P<0.01). In addition, the 15% and 20% Shaoyaotang-containing serum groups had lower levels of IL-6, IL-1β, and TNF-α (P<0.05, P<0.01), lower apoptosis rates (P<0.05, P<0.01), lower protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax (P<0.05, P<0.01), and higher protein and mRNA levels of Bcl-2 (P<0.05, P<0.01) than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can reduce the content of inflammatory factors in Caco-2 cells, down-regulate the protein and mRNA levels of Fas, FasL, Caspase-3, Caspase-9, and Bax, and up-regulate the protein and mRNA levels of Bcl-2 under the intervention of LPS by regulating the Fas/FasL pathway and inhibiting the apoptosis of intestinal epithelial cells in ulcerative colitis.

ObjectiveTo investigate the protective effect and mechanism of Shaoyaotang (SYD) on the lipopolysaccharide (LPS)-induced damage of tight junction proteins in the human colorectal adenocarcinoma (Caco-2) cell model of inflammation via the Ras homolog gene family member A (RhoA)/Rho-associated coiled-coil forming protein kinase (ROCK) pathway. MethodsCaco-2 cells were grouped as follows: Blank, model (LPS, 10 mg·L-1), SYD-containing serum (10%, 15%, and 20%), and inhibitor (Fasudil, 25 μmol·L-1). After 24 hours of intervention, the cell viability in each group was examined by the cell-counting kit 8 (CCK-8) method. Enzyme-linked immunosorbent assay was employed to determine the levels of endothelin-1 (ET-1), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and interleukin-6 (IL-6). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot were employed to determine the mRNA and protein levels, respectively, of RhoA, ROCK2, claudin-5, and zonula occludens-1 (ZO-1) in cells of each group. ResultsCompared with the blank group, the model group showcased a marked reduction in the cell viability (P<0.01), elevations in the levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.01), declines in both mRNA and protein levels of ZO-1 and claudin-5 (P<0.01), and rises in mRNA and protein levels of RhoA and ROCK2 (P<0.01). Compared with the model group, the Shaoyaotang-containing serum (10%, 15%, and 20%) groups had enhanced cell viability (P<0.01), lowered levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.01), up-regulated mRNA and protein levels of ZO-1 and claudin-5 (P<0.05, P<0.01), and down-regulated mRNA and protein levels of RhoA and ROCK2 (P<0.01). Moreover, the inhibitor group and the 15% and 20% Shaoyaotang-containing serum groups had lower levels of ET-1, TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01), higher mRNA and protein levels of ZO-1 and claudin-5 (P<0.05, P<0.01), and lower mRNA and protein levels of RhoA and ROCK2 (P<0.05, P<0.01) than the 10% Shaoyaotang-containing serum group. ConclusionThe Shaoyaotang-containing serum can lower the levels of LPS-induced increases in levels of inflammatory cytokines and endothelin to ameliorate the damage of tight junction proteins of the Caco-2 cell model of inflammation by regulating the expression of proteins in the RhoA/ROCK pathway.

Objective:To investigate the differential impact of ultra-high-resolution photon-counting detector CT (UHR PCD-CT) and energy-integrating detector CT (EID-CT) on image quality and calcified plaque-induced luminal stenosis in coronary CT angiography (CCTA).Methods:This retrospective analysis was conducted on patients who underwent both EID-CT and UHR PCD-CT CCTA at the Geriatric Hospital of Nanjing Medical University between January 2021 and November 2024. A total of 141 patients were included in the study, within 46 patients having scans within a 12-month interval. Image quality of all coronary artery segments was subjectively evaluated. Patients with paired scans (interval≤12 months) were included for calcified plaque analysis. Subjective visualization of calcified plaques evaluated. The blooming artifact was calculated as an objective evaluation index for assessing the calcified plaques. Additionally, the degree of coronary artery lumen stenosis resulting from calcified plaques was assessed, along with the measurement of plaque volume and the Agatston score. Changes in lumen stenosis between the two scans were also evaluated. The Wilcoxon signed-rank test was used to compare the subjective scores of coronary artery image quality and calcified plaques between the two groups, and paired-sample t-tests were used to compare the blooming artifact and lumen stenosis degree. Results:The PCD-CT image quality score was significantly higher than that of EID-CT [PCD-CT : 5 (4,5), EID-CT: 4 (4,5); Z=-21.38, P<0.001]. Compared to EID-CT, PCD-CT reduced the blooming artifact (PCD-CT: 38.88%±9.09%, EID-CT: 50.11%±11.52%; t=-12.97, P<0.001), significantly improving the subjective score for visualization of calcified plaques [PCD-CT: 5 (4,5), EID-CT: 3 (2,3); Z=-9.68, P<0.001], and the measured lumen stenosis was notably lower in PCD-CT(PCD-CT:34.88%±18.20%, EID-CT:45.31%±23.42%; t=-9.93, P<0.001). Among 129 analyzed calcified plaques, luminal stenosis was reduced on PCD-CT in 110 plaques (85.3%) and increased in 19 (14.7%), including 4 plaques that had unclear boundaries with the adjacent lumen in EID-CT CCTA images, making the stenosis difficult to assess. Conclusion:Compared to EID-CT, UHR PCD-CT for CCTA significantly improves coronary artery image quality, provides clearer visualization of calcified plaques and adjacent lumen details, and it can reduce the overestimation of coronary artery caleified plaque stenosis.

ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis (AS). MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group, low drug-containing serum group, medium drug-containing serum group, high drug-containing serum group, and positive drug group. After drug intervention, cell proliferation was measured using the cell counting kit-8 (CCK-8) assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase (ALP) activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin (OCN), osteopontin (OPN), and runt-related transcription factor 2 (Runx2) was detected by Western blot. The mRNA expression levels of Wnt5a, β-catenin, and Dickkopf-1 (DKK-1) were measured by real-time quantitative polymerase chain reaction (Real-time PCR). ResultsCompared with the blank group, each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression (P<0.01). Compared with the blank group, the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression (P<0.05). The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression (P<0.05, P<0.01), with the positive drug group showing the most pronounced effect (P<0.01). The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression (P<0.01). Compared with the blank group, the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins (P<0.05, P<0.01), while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN, OPN, and Runx2 proteins (P<0.05, P<0.01). ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts, thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression, further inhibiting the transcription of downstream target genes.

Objective:
To investigate the Alzheimer's disease (AD) influencing factors among the elderly, so as to provide a basis for early prevention and intervention.
Methods:
From March to June 2024, participants aged 60 years and above from a sub-district in Haishu District, Ningbo City, Zhejiang Province were selected using a convenience sampling method. Data on demographics, lifestyle, and health status were collected through questionnaire surveys. Depressive symptoms were evaluated using the short-form Geriatric Depression Scale. The Chinese Mini-Mental State Examination (MMSE) was used for the initial screening of AD, and individuals who screened positive were further diagnosed by psychiatrists. Factors affecting AD among the elderly were analyzed using a multivariable logistic regression model.
Results:
A total of 3 644 individuals were surveyed, comprising 1 526 males (41.88%) and 2 118 females (58.12%). The mean age was (71.85±7.44) years. AD was detected in 200 cases, with a detection rate of 5.49%. Multivariable logistic regression analysis showed that individuals aged ≥65 years (65-<70 years, OR=3.012, 95%CI: 1.007-9.012; 70-<75 years, OR=3.131, 95%CI: 1.059-9.260; 75-<80 years, OR=5.779, 95%CI: 1.989-16.784; ≥80 years, OR=16.810, 95%CI: 5.926-47.685), those who were unmarried, divorced, or widowed (OR=1.973, 95%CI: 1.383-2.815), those with hearing loss (OR=1.573, 95%CI: 1.128-2.193), those with diabetes mellitus (OR=1.958, 95%CI: 1.362-2.814), and those with depressive symptoms (OR=4.143, 95%CI: 2.997-5.728) had a higher risk of AD. Conversely, individuals with an educational level of primary school or above (primary school, OR=0.579, 95%CI: 0.401-0.835; junior high school or above, OR=0.438, 95%CI: 0.259-0.741), and those who engaged in regular physical exercise (OR=0.414, 95%CI: 0.264-0.649) had a lower risk of AD.
Conclusions
The detection rate of AD was relatively high among the elderly in Haishu District. AD among the elderly was related to age, educational level, marital status, physical exercise, hearing loss, diabetes mellitus, and depressive symptoms.
