Objective:To explore the effectiveness of 18F-deuterated-Florbetapir (D3FSP) PET/CT imaging in detecting β-amyloid (Aβ) deposition in the brain and its correlation with plasma biomarkers. Methods:A retrospective analysis was conducted on 79 patients (32 males, 47 females; age(66±7)years) who underwent 18F-D3FSP PET/CT imaging from June 2022 to November 2023 at the First Affiliated Hospital, Guangzhou Medical University, as a part of the Greater Bay Area Healthy Aging Brain Longitudinal Cohort Study (GHABS). Based on the Alzheimer′s Disease Neuroimaging Initiative cohort standard protocol, patients were categorized into cognitively unimpaired (CU) group, mild cognitive impairment (MCI) group, and Alzheimer′s disease (AD) group. Brain regions were segmented using the AW workstation and the SUV ratio (SUVR) was calculated with the cerebellum as the reference region. One-way analysis of variance, Bonferroni correction and Pearson correlation analysis were used to analyze data. The ROC curve analysis was used to analyze the cut-off value and the diagnostic efficacy of SUVR. Results:There were 48, 15 and 16 cases in CU, MCI and AD groups respectively. During the transition from CU to MCI and then to AD, there was a rising trend in SUVR ( F values: 11.15-22.38, all P<0.001) across the whole brain and various brain regions (bilateral frontal lobes, bilateral anterior cingulate gyrus, bilateral precuneus, bilateral parietal lobes, bilateral lateral temporal lobes, and bilateral occipital lobes). SUVRs of the right anterior cingulate gyrus and bilateral precuneus were different between the CU and MCI groups (all P<0.017), and those of bilateral frontal lobes, right precuneus, bilateral parietal lobes, bilateral lateral temporal lobes, and bilateral occipital lobes were different between the MCI and AD groups (all P<0.017). SUVRs of brain regions were negatively correlated with cognitive scale scores ( r values: from -0.57 to -0.37, all P<0.001), and were positively correlated with plasma phosphorylated tau181 (p-tau181, r values: 0.50-0.61, all P<0.001). The ROC curve analysis suggested that the cut-off value of SUVR in the precuneus for distinguishing CU from AD was 1.20, with the AUC, sensitivity, specificity and accuracy of 0.85, 12/16, 91.7%(44/48)and 87.5%(56/64), respectively. Conclusion:18F-D3FSP PET/CT imaging has good clinical application value in assessing the deposition sites and the extent of Aβ in the brain, which is related to clinical cognition and plasma p-tau181 level.

OBJECTIVE To study the effects of Yishen daluo decoction on inflammatory factors and cyclic adenosine monophosphate(cAMP)/protein kinase A (PKA)/cAMP response element binding protein (CREB) signal pathway in experimental autoimmune encephalomyelitis (EAE) model mice by inhibiting the expressions of β-arrestin1, and to explore the mechanism of Yishen daluo decoction in the treatment of EAE. METHODS Sixty mice were randomly divided into normal group, model group, TCM group (Yishen daluo decoction 20 g/kg), positive control group (prednisone acetate 3.9 mg/kg), β-arrestin1 siRNA adeno- associated virus (AAV-β) group, AAV-β+TCM group, with 10 mice in each group. Except for normal group, EAE model was made in other groups. AAV-β group and AAV-β+TCM group were injected with AAV-β via tail vein to interfere with the expression of β -arrestin1 protein. Starting from the 8th day of modeling, they were given corresponding drug solution/normal saline intragastrically, once a day, for consecutive 14 days. The neurological function score of mice was detected; the pathological and morphological changes were observed in the brain and spinal cord tissues of mice; the serum levels of inflammatory factors [interleukin-2 (IL-2), IL-23, interferon-γ (IFN-γ)] in mice were determined; the expressions of β-arrestin1, cAMP, PKA and CREB in brain and spinal cord were detected. RESULTS Compared with normal group, neurological function scores, serum levels of inflammatory factors, and protein expressions of β-arrestin1 in brain and spinal cord were significantly increased (P<0.05 or P< 0.01); protein expressions of PKA, CREB and cAMP in brain and spinal cord were decreased significantly(P<0.05 or P<0.01). The deep staining of cellular shrinkage and aggregation of inflammatory cells were observed in most neurons of the brain and spinal cord, with varying degrees of demyelinating. Compared with model group, the neurological function scores, pathological changes in brain and spinal cord tissues, and most indicators (except for CREB and cAMP proteins in the brain tissue of AAV-β group) were significantly reversed (P<0.05 or P<0.01).Compared with AAV- β group, the neurological function scores, the levels of IFN-γ in serum and β-arrestin1 in spinal cord were significantly decreased (P<0.05 or P<0.01), PKA and cAMP in brain and spinal cord tissues were significantly increased in AAV- β +TCM group (P<0.05 or P<0.01). CONCLUSIONS Yishen daluo decoction can inhibit the expression of β-arrestin1 in the central nervous system thus activating the cAMP/PKA/CREB signaling pathway, relieving nervous system inflammation, and ultimately alleviates the symptoms of EAE.

Postoperative adhesion (PA) is currently one of the most unpleasant complications following surgical procedures. Researchers have developed several new strategies to alleviate the formation of PA to a great extent, but so far, no single measure or treatment can meet the expectations and requirements of clinical patients needing complete PA prevention. Chinese medicine (CM) has been widely used for thousands of years based on its remarkable efficacy and indispensable advantages CM treatments are gradually being accepted by modern medicine. Therefore, this review summarizes the formating process of PA and the efficacy and action mechanism of CM treatments, including their pharmacological effects, therapeutic mechanisms and advantages in PA prevention. We aim to improve the understanding of clinicians and researchers on CM prevention in the development of PA and promote the in-depth development and industrialization process of related drugs.

A small proportion of mononuclear diploid cardiomyocytes (MNDCMs), with regeneration potential, could persist in adult mammalian heart. However, the heterogeneity of MNDCMs and changes during development remains to be illuminated. To this end, 12 645 cardiac cells were generated from embryonic day 17.5 and postnatal days 2 and 8 mice by single-cell RNA sequencing. Three cardiac developmental paths were identified: two switching to cardiomyocytes (CM) maturation with close CM-fibroblast (FB) communications and one maintaining MNDCM status with least CM-FB communications. Proliferative MNDCMs having interactions with macrophages and non-proliferative MNDCMs (non-pMNDCMs) with minimal cell-cell communications were identified in the third path. The non-pMNDCMs possessed distinct properties: the lowest mitochondrial metabolisms, the highest glycolysis, and high expression of Myl4 and Tnni1. Single-nucleus RNA sequencing and immunohistochemical staining further proved that the Myl4+Tnni1+ MNDCMs persisted in embryonic and adult hearts. These MNDCMs were mapped to the heart by integrating the spatial and single-cell transcriptomic data. In conclusion, a novel non-pMNDCM subpopulation with minimal cell-cell communications was unveiled, highlighting the importance of microenvironment contribution to CM fate during maturation. These findings could improve the understanding of MNDCM heterogeneity and cardiac development, thus providing new clues for approaches to effective cardiac regeneration.

Objective:To evaluate the long-term efficacy of endoscopic transluminal drainage(ETD) for acute pancreatitis complicated with walled-off necrosis (WON) or pancreatic pseudocyst (PPC).Methods:A total of 79 patients who were diagnosed as having WON or PPC by abdominal CT or ultrasound and treated with ETD in Nanjing Drum Tower Hospital were enrolled. Past medical records and follow-up by phone call after discharge were analyzed for long-term outcomes including endocrine and exocrine functions and long-term quality of life.Results:A total of 50 patients were enrolled, including 31 patients with infected WON/PPC and 19 patients with uninfected WON/PPC. Seventeen patients (54.84%) in the infected WON/PPC group and 11 patients (57.89%) in the uninfected WON/PPC group lost 5% or more of their weight. There were no significant differences in the proportion of cases of weight loss of 5% or more ( P=0.833), or the weight loss between the two groups (12.59±8.89 kg VS 10.91±2.47 kg, P=0.522). Only one patient in the infected WON/PPC group had chronic abdominal pain. There was no significant difference in the Izbicki score between the two groups (23.79±6.74 VS 22.03±3.21, P=0.295). None of the patients developed steatorrhea after discharge. Five patients (16.67%, 5/30) in the infected WON/PPC group and 6 patients (40.00%, 6/15) in the uninfected WON/PPC group developed endocrine insufficiency with no significant difference ( P=0.140). Greater risk of secondary diabetes resulted from higher low-density lipoprotein cholesterol ( HR=1.9, 95% CI: 1.0-3.4, P=0.044)and triglycerides ( HR=1.2, 95% CI: 1.0-1.3, P =0.029). Conclusion:ETD is safe and effective for WON and PPC. But there is possibility that patients develop secondary diabetes. Additionally, greater risk of secondary diabetes results from higher low-density lipoprotein cholesterol and triglycerides.

Objective:To investigate the preference for Front-of-Pack Labeling (FOP) and its association with the understanding of the Nutrition Facts Panel among Chinese residents.Methods:A multi-stage sampling strategy was adopted to select 3 002 people aged between 18 and 70 years old from the eastern region of China (Beijing, Jiangsu Province, Guangdong Province), the northeast region (Heilongjiang Province), the central region (Henan Province) and the western region (Sichuan Province) from July 2020 to March 2021. Socio-demographic characteristics of participants and their understanding of the Nutrition Facts Panel and preference for FOP were collected. The χ2 test was conducted to compare the preference for FOP in different groups of population, and multivariate logistic regression was used to analyze the association between the preference for FOP and the understanding of the Nutrition Facts Panel. Results:The mean age of 3 002 participants was (42.3±13.4) years, of which 1 914 (63.8%) were females and 69.3% could not understand the Nutrition Facts Panel. About 2 458 respondents (81.9%) suggested that FOP could be promoted. The top three nutrients that should be labeled were sugar (68.4%), salt (68.2%) and total fat (62.4%). The number of participants who believed that the Multiple Traffic Lights (MTL) could be easier to help consumers to quickly choose healthy food, attract attention and provide the most needed information was 1 064 (35.4%), 1 026 (34.2%) and 1 140 (38.0%), respectively. The multivariate logistic regression analysis showed that, compared with the Guideline Daily Amount (GDA) system, participants who could not understand the Nutrition Facts Panel preferred (1) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could quickly help you choose food more easily?"[ OR (95% CI): 2.21 (1.62-3.02), 1.64 (1.22-2.22), 1.79 (1.31-2.45), respectively]; (2) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could attract your attention the most?"[ OR (95% CI): 2.62 (1.92-3.59), 1.96 (1.45-2.66), 2.25 (1.66-3.04), respectively]; and (3) Nutri-Score, Warning labels, and Health logos: Smart Choice in terms of"Which format of FOP could provide you with the most needed information?"[ OR (95% CI): 2.33 (1.70-3.21), 2.21 (1.66-2.95), 2.01 (1.50-2.71), respectively]. Conclusion:The residents from six provinces in China have a supportive attitude towards FOP. The interpretive FOP with color information, specific nutrient information and summary indicator can be launched. The nutrition information of sugar, salt and total fat could be prioritized to be labeled on the FOP.
