    Abstract Objective: To explore the relationship between calcification of human vascular system and local inflammation using PET / CT. Methods: Patients who were treated with concurrent PET / CT in our hospital were collected continuously, and their arterial image data were analyzed in parallel with standardized uptake values. (SUV) and corresponding slice calcification score (CS) measurement. SUV values were collected and measured for slices with CS greater than 100. Patients were grouped according to CS, and the correlation analysis between SUV values and CS in each group was performed. Results: Overall CS and SUVmax (r = 0.62, P <0.05) and SUVmean (r = 0.59, P <0.05) were positively correlated, among which CS and SUV values were in the SUVmax (r = 0.72, P <0.05), SUVmean ( r = 0.59, P <0.05), SUVmax of CS 200- 299 group (r = 0.71, P <0.05), SUVmean (r = 0.80, P <0.05), SUVmax of CS 300-399 group (r = 0.47, P <0.05 ), SUVmean (r = 0.53, P <0.05) were positively correlated, SUVmax (r = -0.17, P> 0.05), SUVmean (r = -0.07, P> 0.05) were negatively correlated in CS 400-499 group, CS There was no significant correlation between SUVmax (r = 0.22, P> 0.05) and SUVmean (r = 0.18, P> 0.05) in the ≥500 group. Conclusion: There is a certain correlation between the local vascular calcification area and the corresponding local inflammatory response in the calcification progress PET / CT has the potential to monitor early calcification.

    Abstract Background: Children with hypothyroidism typically present with delayed growth and development, but on rare occasions can present with signs of precocious puberty. This presentation is called Van Wyk-Grumbach syndrome. Van Wyk-Grumbach syndrome has seldom been described in patients with trisomy 21.
    Case presentation: We present the case of a 4-year-old girl with trisomy 21, who recently moved to the United States from Guyana, and presented to the emergency room with recurrent vaginal bleeding. She was eventually diagnosed with hypothyroidism and Van Wyk-Grumbach syndrome. She was noted to have Tanner I breasts and pubic hair. A pelvic ultrasound was performed, which showed a simple cyst in the right adnexa. Subsequent laboratory evaluation revealed a thyroid stimulating hormone (TSH) of > 150 mIU/ml along with low free thyroxine of 0.3 ng/dl, suggesting longstanding untreated hypothyroidism. Estradiol and alpha-fetoprotein (AFP) levels were elevated. Bone age was delayed. The patient was diagnosed with Van Wyk-Grumbach syndrome and was started on levothyroxine therapy with subsequent resolution of vaginal bleeding. Estradiol and AFP both normalized after initiating levothyroxine therapy.
    Conclusion: This case emphasizes the importance of recognizing the presence of precocious puberty, delayed bone age and ovarian cyst as a manifestation of primary hypothyroidism. In addition, it highlights the need for thyroid function screening in patients with Trisomy 21. Tumor markers may be elevated in Van Wyk-Grumbach syndrome with subsequent normalization after treatment.

    Abstract The most common malignancy in women is breast cancer, and the second one is colon cancer. Synchronous breast and colon cancers are rare. Here, we reported a 60-year-old woman with a left breast mass for six months. Biopsy revealed an invasive ductal carcinoma. She underwent 2-[Fluorine-18]fluoro-2-deoxy-D-glucose (FDG) positron emission tomography (PET)/computed tomography (CT) scan for evaluation of the extent of the disease. FDG PET/CT revealed an advanced left breast cancer with multiple metastases in both regional and distant lymph nodes (in left axilla level I/II, lower paratracheal region, and right lung hilum), bilateral lungs, and axial and proximal appendicular skeletons. An early staged synchronous colon cancer was detected incidentally on FDG PET/CT images. After endoscopic mucosal resection of colon cancer, she received palliative chemotherapy for breast cancer with a marked therapeutic response. The disease status of post-treated breast cancer remained relatively stationary for more than one year. Brain metastasis was noted afterward. Nevertheless, there was no evidence of colon cancer recurrence throughout her breast cancer disease course.

    Abstract Objective: Congenital adrenal hyperplasia (CAH) is an inherited condition in which individuals require multiple daily doses of medication and are at risk for life-threatening adrenal crisis. The chronic nature and severity of CAH place children at risk for psychiatric morbidity. The aim was to assess the degree of anxiety and depressive symptoms in children with CAH.
    Methods: A cross-sectional cohort study of children (7-17 years) with CAH and their caregivers were recruited between May and December 2021. Children with hypothyroidism (HT) and their caregivers served as unaffected controls. Validated mental health questionnaires [Children’s Depression Inventory 2 Self Report-Short (CDI-2), Screen for Child Anxiety Related Disorders (SCARED), Patient Health Questionnaire modified for Adolescents (PHQ-A); self and proxy] were completed by participants at one clinic visit. Higher scores indicated greater symptoms of anxiety and depression.
    Results: A total of 60 children and 56 parents participated. Among the children 34 had CAH (68% female, mean age 11.41±2.5, CAH duration 8.5±4.1) and 26 had HT (73% female, mean age 12.7±2.9 years, HT duration 6.0±4.2 years). There was no increase in anxiety and depression symptoms in children with CAH compared to controls. In sub-analyses, children with CAH and controls reported a greater number of anxiety and depression symptoms than their caregivers on the SCARED and CDI-2, respectively. There was no association between adrenal control and the degree of anxiety or depression symptoms.
    Conclusion: Children with CAH do not have more symptoms of anxiety or depression compared to controls. Child and caregiver-proxy responses lack agreement, suggesting that children with CAH may continue to benefit from routine mental health evaluation, regardless of voiced caregiver concern.

    Abstract The retinal ganglion cells (RGCs) serve as the critical pathway for transmitting visual information from the retina to the brain, yet they can be dramatically impacted by diseases such as glaucoma. When investigating disease processes affecting RGCs in mouse models, accurately quantifying affected cells becomes essential. However, the use of pan RGC markers like RBPMS or THY1 presents challenges in accurate total cell counting. While Brn3a serves as a reliable RGC nuclear marker for automated counting, it fails to encompass all RGC subtypes in mice. To address this limitation and enable precise automated counting, our research endeavors to develop a method for labeling nuclei in all RGC subtypes. Investigating RGC subtypes labeled with the nuclear marker POU6F2 revealed that numerous RGCs unlabeled by Brn3a were, in fact, labeled with POU6F2. We hypothesize that using antibodies against both Brn3a and POU6F2 would label virtually all RGC nuclei in the mouse retina. Our experiments confirmed that staining retinas with both markers resulted in the labeling of all RGCs. Additionally, when using the cell body marker RBPMS known to label all mouse RGCs, all RBPMS-labeled cells also exhibited Brn3a or POU6F2 labeling. This combination of Brn3a and POU6F2 antibodies provides a pan-RGC nuclear stain, facilitating accurate automated counting by labeling cell nuclei in the retina.

    Abstract In this article, an in-depth study and analysis of economic structure are carried out using a neural network fusion release algorithm. The method system defines the weight space and structure space of neural networks from the perspective of optimization theory, proposes a bionic optimization algorithm under the weight space and structure space, and establishes a neuroevolutionary method with shallow neural network and deep neural network as the research objects. In the shallow neuroevolutionary, the improved genetic algorithm (IGA) based on elite heuristic operation and migration strategy and the improved coyote optimization algorithm (ICOA) based on adaptive influence weights are proposed, and the shallow neuroevolutionary method based on IGA and the shallow neuroevolutionary method based on ICOA are applied to the weight space of backpropagation (BP) neural networks. In deep neuroevolutionary method, the structure space of convolutional neural network is proposed to solve the search space design of neural structure search (NAS), and the GA-based deep neuroevolutionary method under the structure space of convolutional neural network is proposed to solve the problem that numerous hyperparameters and network structure parameters can produce explosive combinations when designing deep learning models. The neural network fusion bionic algorithm used has the application value of exploring the spatial structure and dynamics of the socioeconomic system, improving the perception of the socioeconomic situation, and understanding the development law of society, etc. The idea is also verifiable through the present computer technology.

    Abstract Abstract Objective The aim of the present study was to explore the prognostic role of γδ T cells in colorectal cancer, and establish a nomogram for predicting the survival of the patients. Methods Immunohistochemistry was performed to analyze the infiltration degree of γδ T cells in tumor and normal tissues of colorectal cancer. The relationship between γδ T cells infiltration in tumor tissues and the prognosis of patients with colorectal cancer were determined by Cox regression analysis and survival analysis. R software was used to establish and verify a nomogram for predicting the prognosis of patients with colorectal cancer. Results The degree of γδ T cell infiltration in tumor tissues and normal tissues of CRC was not different (t = 0.35, P = 0.73). However, the infiltration of γδ T cell was related to the survival status of the patients (x 2 = 4.88, P = 0.03). Besides, the infiltrating degree of γδ T cells in tumor tissue was obviously related to the prognostic improvement of the patients with colorectal cancer (log-rank P = 0.02) and could reflect the benefit of adjuvant chemotherapy. The nomogram based on tumor diameter, tumor location, AJCC stage, chemotherapy, serum CEA level and γδ T cell infiltration was established and could provide a reference for predicting the survival of colorectal cancer patients. Conclusion γδ T cell infiltration degree in tumor tissue was an important factor to improve the outcome of patients with colorectal cancer, and can predict the benefit of adjuvant chemotherapy.

    Abstract Introduction: Glucocorticoid therapy in children with congenital adrenal hyperplasia (CAH) must be finely balanced between optimizing adrenal control and minimizing side effects. Twice (BID) rather than three times daily (TID) hydrocortisone may provide similar adrenal control and reduce metabolic risk. We compared BID and TID regimens with respect to adrenal control, growth, and metabolic effects.
    Methods: A retrospective chart review (n = 128 visits, 36 individual patients) of prepubertal children with classical CAH was conducted at a tertiary care center between March 2007 and February 2020. Adrenal control, growth, and metabolic data were extracted in those taking hydrocortisone BID versus TID. Univariate generalized estimating equations models were performed to analyze the effect of dose frequency on outcomes of interest.
    Results: Overall, we found no difference in adrenal control (8% vs. 18% poor control) or testosterone levels (9.65 ng/dL vs. 7.62 ng/dL) between the BID versus TID groups. We detected no difference in growth velocity (6.86 vs. 6.32 cm/year) or bone age advancement (11.3 vs. 5.91 months) between the groups. There was no difference in daily steroid dose (12.1 vs. 11.7 mg/m2/day), BMI Z-score (0.43 vs. 0.31), or systolic blood pressure percentile (65.5 vs. 61.7).
    Conclusion: BID dosing provides similar adrenal control and does not appear to impact growth or bone age advancement. On the other hand, TID dosing does not appear to increase the metabolic side effect profile in this age-group. Dosing should be patient-centered with individualized consideration.

    Abstract Background and objectives: Dietary control and increased physical activity (PA) are recommended for patients with metabolic (dysfunction-) associated fatty liver disease (MAFLD). However, not all patients can sustain both exercise and a healthy diet. This study explored the interaction between dietary quality, PA levels, and mortality in MAFLD patients.
    Methods: The Third National Health and Nutrition Examination Survey and linked mortality data were used in this study. Diet quality was assessed with the Healthy Eating Index (HEI). PA level was calculated by multiply self-reported exercise frequency and its Metabolic Equivalent A high-quality diet was associated. A Cox proportional hazard model was used to explore risk factors for mortality in MAFLD patients.
    Results: In total, 3709 participants with MAFLD were included in the final analysis. The median follow-up time was 26.2 (interquartile range 19.3-28.1) years and 1549 (41.8%) deaths were recorded over follow-up. Cox multivariate regression was used to adjust for potential confounders of mortality. The results showed both HEI score and PA level were inversely correlated with all-cause mortality (P < 0.05). In the subgroup analysis stratified by PA level, higher diet quality decreased all-cause mortality, cardiovascular-related mortality and cancer-related mortality in PA inactive of MAFLD patients (P < 0.05), but these correlations were not present in active PA groups.
    Conclusion: Healthy diet and physical activity may have different impact as lifestyle interventions for MAFLD. A high-quality diet is associated less mortality in inactive individuals with MAFLD but not in those with active PA levels. Sedentary individuals require healthier diet.

    Abstract Uric acid (UA) is associated with non-alcoholic fatty liver disease (NAFLD). However, it is unclear whether UA plays a predictive role in NAFLD prognosis. This study aimed to explore the relationship between UA levels and mortality in NAFLD patients without severe renal disease. Data were obtained from the Third National Health and Nutrition Examination Survey (NHANES). Time-dependent Cox regression was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) for mortality. Overall, 2493 individuals with NAFLD and estimated glomerular filtration rate (eGFR) > 60 mL/min/1.73 m
