    Abstract Drug attrition rates have increased over the past few years, accompanied with growing costs for the pharmaceutical industry and consumers. Lack of in vitro models connecting the results of toxicity screening assays with clinical outcomes accounts for this high attrition rate. The emergence of cardiomyocytes derived from human pluripotent stem cells provides an amenable source of cells for disease modeling, drug discovery, and cardiotoxicity screening. Functionally similar to to embryonic stem cells, but with fewer ethical concerns, induced pluripotent stem cells (iPSCs) can recapitulate patient-specific genetic backgrounds, which would be a huge revolution for personalized medicine. The generated iPSC-derived cardiomyocytes (iPSC-CMs) represent different subtypes including ventricular-, atrial-, and nodal-like cardiomyocytes. Purifying these subtypes for chamber-specific drug screening presents opportunities and challenges. In this chapter, we discuss the strategies for the purification of iPSC-CMs, the use of iPSC-CMs for drug discovery and cardiotoxicity test, and the current limitations of iPSC-CMs that should be overcome for wider and more precise cardiovascular applications.

    Abstract Heavy metals are harmful environmental pollutants that have attracted widespread attention due to their health hazards to human cardiovascular disease. Heavy metals, including lead, cadmium, mercury, arsenic, and chromium, are found in various sources such as air, water, soil, food, and industrial products. Recent research strongly suggests a connection between cardiovascular disease and exposure to toxic heavy metals. Epidemiological, basic, and clinical studies have revealed that heavy metals can promote the production of reactive oxygen species, which can then exacerbate reactive oxygen species generation and induce inflammation, resulting in endothelial dysfunction, lipid metabolism distribution, disruption of ion homeostasis, and epigenetic changes. Over time, heavy metal exposure eventually results in an increased risk of hypertension, arrhythmia, and atherosclerosis. Strengthening public health prevention and the application of chelation or antioxidants, such as vitamins and beta-carotene, along with minerals, such as selenium and zinc, can diminish the burden of cardiovascular disease attributable to metal exposure.

    Abstract Objective To study the normal reference values of intracranial pressure and cerebral perfusion pressure in children of different ages. Methods A retrospective study was conducted on the children with simple epidural hematoma who received hematoma removal and implantation for intracranial pressure monitoring in our department from January 2015 to June 2022.The intracranial pressure and arterial blood pressure of the children were monitored per hour after surgery, and the changes in intracranial pressure and cerebral perfusion pressure were analyzed based on time and age in different age groups.The intracranial pressure and cerebral perfusion pressure in stable period (72 h after surgery) were used as the relative normal reference values, and the 95% range of intracranial pressure and cerebral perfusion pressure were calculated statistically by percentile method as the reference range. Results A total of 207 children were included in this study, including 25 in the < 2-year-old group, 82 in the 2~6-year-old group and 100 in the >6-year-old group.Intracranial pressure in different age groups was increased rapidly after a short period of low level, while cerebral perfusion pressure experienced a short period of high level, and both reached a peak and a trough from 12 to 24 h after surgery, and gradually reached a stable range at 72 h after surgery.The range of intracranial pressure 72 h after surgery was 3.0~8.0 mmHg for the < 2-year-old group, 5.0~11.0 mmHg for the 2~6-year-old group, and 6.0~14.0 mmHg for the >6-year-old group.Cerebral perfusion pressure range was 50.9~68.7, 55.0~73.3, and 57.3~79.6 mmHg, respectively for the above 3 age groups. Conclusion The normal ranges of intracranial pressure and cerebral perfusion pressure are different in children of different ages, and we suggest increasing with age.

    Abstract A chemiluminescent immunoassay for human serum Cystatin C (Cys C) was established using a direct-antibody sandwich model. The immunoassay kit uses magnetic separation technology, using magnetic particles as the reaction solid phase, alkaline phosphatase as the marker enzyme, and a new chemiluminescent substrate APLS as the substrate. It has the characteristics of high sensitivity and short reaction time. This product uses high-affinity antibodies, resulting in a high specificity. The established method showed good accuracy, uniformity, and stability. The limit of detection was 2.39 ng/mL. The intra-assay coefficient of variation (CV) was 3.36%-6.00%, the interassay CV was 4.12%-5.35%, and the recovery rate was 99.07%. The correlation coefficient (r) of Cys-C kit was 0.999388 ≥ 0.9900. The accuracy of the developed method was tested by automatic chemiluminescence instrument (P > 0.05). The lowest titer was 0.92500, and the highest was 1.10000. The developed method showed a good correlation with the product from Roche by comparing these two kits in 240 clinical samples from China. In total, 1392 clinical patient from China samples were measured using the reagent kit developed in this study.

    Abstract The mental health of older adults has become one of the major health challenges facing society today, which has attracted wide concerns from scholars in urban areas, but research in rural areas has been neglected. Therefore, this paper took rural older adult residents of 11 sample villages in Jintang County, Chengdu City, Sichuan Province, as the research object. After controlling the demographic characteristics of older adults in rural areas, this paper attempted to explore the effects of the rural built Environment on the mental health of older adults. Through field investigation in the sample villages, 515 valid questionnaires were obtained. The results from the Binary Logistic Regression Model show that good marital status, physical health, education level, well-constructed roads, and safe neighborhoods had significant positive effects on the mental health of rural older adults. Rural older adults who prefer to walk, cycle, and use public transport have better mental health, and accessibility to the periodic market, health station, bus station, village committee, supermarket, and the main road is positively correlated with the mental health of rural older adults, while the distance from home to the town center and coach terminal has a significant negative impact on the mental health of rural older adults. The research results provide a theoretical reference for further construction of rural aging environments.

    Abstract Purpose: Trajectory changes of quality of life (QOL) and psychological status in patients with T1N0M0 papillary thyroid cancer (PTC) after microwave ablation (MWA) treatment.
    Methods: Patients with T1N0M0 PTC who underwent MWA from March to August 2021 were included in this study. Patients completed the European Organisation for Research and Treatment of Cancer questionnaire (QLQ-C30), Thyroid Cancer-Specific Quality of Life Questionnaire (THYCA-QOL) and Hospital Anxiety and Depression Scale (HADS) at baseline, 3 months, 6 months, 9 months and 12 months after MWA.
    Results: 181 patients were enrolled in this study. All patients met a minimum of 12 months of follow-up. The QOL at baseline and 12 months after MWA were 14.95 ± 1.78 and 14.19 ± 1.73 (P < 0.01), respectively. Patients' anxiety was 3.33 ± 1.81 and 1.49 ± 2.14 (P < 0.01), respectively. Patients' depression was 2.14 ± 2.10 and 1.40 ± 2.22 (P < 0.01), respectively. In the trajectory analysis, 73%, 19% and 8% of patients achieved significant improvement, slight improvement and stable in QOL, respectively, with older, female, lower education and lower monthly income as the risk factors of QOL. 63%, 31% and 6% of patients achieved significant improvement, slight improvement and stable in anxiety, respectively, with younger, female, lower education, lower monthly income, unmarried or divorced and higher T3, T4 levels as the risk factors of anxiety. 72%, 21% and 7% of patients achieved significant improvement, slight improvement and stable in depression, respectively, with younger, lower monthly income and unmarried or divorced as the risk factors of depression.
    Conclusions: MWA can effectively improve the QOL and emotional distress of patients with T1N0M0 PTC.

    Abstract Maxillofacial arteriovenous malformation located in the sensitive parts of the nose and lips has been an arduous challenge for doctors to meet a balance between resection and aesthetics in one time. In this report, one patient with a giant arteriovenous malformation covering the forehead, the nose, the lip, and bilateral cheeks and resulting in the appearance of the face like a lion's face, can not meet satisfactory outcomes by other therapeutic methods. We successfully reduced the size of vascular lesion using low-power and short-duration microwave ablation under real-time ultrasound guidance. In the two-year follow-up, the patient's face almost recovered to normality. Microwave ablation is expected to be a new alternative therapy for the treatment of maxillofacial arteriovenous malformations. Laryngoscope, 133:2984-2987, 2023.
