ABSTRACT
Hypoxemia is a common complication of pneumonia, asthma, and bronchopulmonary dysplasia in children.Rapid identification of hypoxemia is of great significance for the disposal and management of critical children.Pulse oximetry is recognized by the World Health Organization as the best way to monitor hypoxemia in children, and it can monitor pulse oxygen saturation noninvasively and continuously.Based on the related literature at home and abroad, combined with the clinical needs of pediatrics, the " Expert consensus on clinical application of pulse oximetry in children" is formulated to improve the understanding of pediatricians and nurses on the application in pediatric clinical practice, principle, operation techniques, and limitations of pulse oximetry.
ABSTRACT
Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.
ABSTRACT
Thyroid cancer is the most common malignant tumor of the endocrine system, and the incidence is increasing year by year, which seriously threatens people's health. Autophagy is a programmed mode of death that can be used as a potential target for anti-tumor therapy and plays an important regulatory role. Leucine-rich repeat kinase 2 (LRRK2) is a protein kinase encoded by PARK8 gene. The recent studies have confirmed that autophagy is closely related to thyroid cancer. This paper analyzes the possible regulatory mechanism of LRRK2 affecting thyroid cancer through autophagy, providing new ideas for basic research and clinical diagnosis and treatment of thyroid cancer.
ABSTRACT
Alzheimer's disease (AD) is a common degenerative disease of the central nervous system in the elderly, with memory impairment and behavioral changes as the main clinical manifestations. Modern research has demonstrated that many herbs with both medicinal and edible values have anti-oxidation and anti-aging activities. In addition, these herbs are naturally safe and play a role in disease prevention and health care. The 110 medicinal and edible herbs announced by the National Health Commission of the People's Republic ofChina in 2021 were studied. The relevant papers published in the last five years were searched against CNKI, VIP, Wanfang Data, PubMed and other databases. The effects, mechanism, and active ingredients of the medicinal and edible herbs against Alzheimer's disease were summarized. The results showed that more than 30 herbs including Ginseng Radix et Rhizoma, Curcumae Longae Rhizoma, Astragali Radix, Corni Fructus, Gastrodiae Rhizoma, Angelicae Sinensis Radix, Cistanches Herba, Croci Stigma, Glycyrrhizae Radix et Rhizoma, Ganoderma and their active ingredients were effective in the prevention and treatment of Alzheimer's disease. Among them, ten herbs that met the requirements were screened out for analysis. The medicinal and edible herbs and their active ingredients can act on multiple targets and treat Alzheimer's disease via multiple signaling pathways such as nuclear factor-κB (NF-κB), mitogen-activated protein kinase 5 (MEK5)/extracellular signal-regulated kinase 5 (ERK5), cytochrome C (CytC) and cysteine aspartate-specific protease (Caspase)-3/(Caspase)-9, Wnt/β-catenin, and brain-derived neurotrophic factor (BDNF)/tyrosine kinase receptor B (TrkB)/phosphatidylinositol 3-kinase (PI3K)/protein kinase B (Akt), thus improving learning, cognitive ability, and memory ability. Most of the medicinal and edible herbs have the tropism to the heart, spleen, liver, and kidney meridians and tonifying effect.

ABSTRACT
Thyroid cancer is the most common head and neck malignant tumor, and its incidence is increasing year by year. Therefore, it is of great significance to explore the mechanism of the occurrence and development of thyroid cancer, and develop the diagnostic markers and therapeutic targets of thyroid cancer, so as to improve the curative effect of thyroid cancer and prolong the survival time of patients. The previous study has found that long non-coding RNA (lncRNA) DANCR has abnormal high expression in thyroid cancer, which could promote the expression of leucine-rich repeat kinase 2 (LRRK2) by affecting miRNA-185-5p and transcription factor SMARCB1, and indirectly participate in autophagy and regulate the development of thyroid cancer. LncRNA DANCR is expected to become a new target for diagnosis and treatment of thyroid cancer. This paper introduces the possible regulatory mechanism of lncRNA DANCR in thyroid cancer, and provides new ideas for the basic research and clinical diagnosis and treatment of thyroid cancer.

ABSTRACT
Ferroptosis is a newly discovered form of cell death in recent years. Its essence is the cell peroxidation death caused by the accumulation of intracellular lipid reactive oxygen species (L-ROS) in a iron-dependent manner. As a highly efficient ferroptosis inducer, Erastin mediates ferroptosis through multiple molecules, such as cystine-glutamate transport receptor, voltage-dependent anion channel and p53. More importantly, Erastin can enhance the sensitivity of cancer cells to chemotherapy and radiotherapy, so it can be used as a new type of anticancer drug. This article reviews the discovery of Erastin, the pathways of ferroptosis, the pathways of Erastin-induced ferroptosis, the anti-tumor characteristics of Erastin, and the latest domestic and international research results.

ABSTRACT
OBJECTIVE: To evaluate the application of individualization dosage auxiliary system JPKD and SmartDose in individualization administration of vancomycin. METHODS: A retrospective study was conducted among adult inpatients in Hainan Provincial People’s Hospital from Apr. 2018 to Mar. 2019 with intravenous use of vancomycin. SmartDose was used to predict the steady blood trough concentration of vancomycin in the initial dosage regimen, and the absolute weight deviation and relative prediction error between the measured concentration and the predicted concentration were calculated. The effects of body mass index (BMI) and acute kidney injury (AKI) on absolute weight deviation were analyzed by χ2 test or continuously corrected χ2 test. Vancomycin drug delivery scheme was adjusted for patients with ungualified steady blood drug trough concentration. JPKD and SmartDose system were used to predict the blood concentration of vancomycin after adjusting the dosage regimen. The absolute weight deviation and relative prediction error between the measured concentration and the predicted concentration were calculated. The prediction ability of the two systems was evaluated and 3 examples was analyzed. RESULTS: Predicted steady blood trough blood concentration of 85 included patients in SmartDose predicted initial dosage regimen were (11.36±5.96) μg/mL (2.34-29.33 μg/mL); the measured concentration was (11.44±6.57) μg/mL (3.10-29.50 μg/mL); absolute weight deviation was 22.95%, and the relative prediction error was 2.72%. Whether BMI was normal or not had significant effects on the absolute weight deviation (χ2=4.75, P=0.029), and whether AKI occurred or not had no significant effects on the absolute weight deviation (χ2=0.236, P=0.627). JPKD and SmartDose predicted that predicted steady blood trough concentrations of vancomycin in 22 included patients were (11.06±3.58) and (12.15±4.35) μg/mL, and the measured concentration was (12.57±4.50) μg/mL; absolute weight deviations were 18.30% and 18.68%; relative prediction errors were -8.65% and -0.44%, respectively. The absolute weight deviations of the predicted values of the two systems were less than 30%. The absolute weight deviations of prediction results were also less than 30% in 3 patients. CONCLUSIONS: JPKD and SmartDose system have good predictive ability for blood concentration of vancomycin in clinical application, and can be used to optimize the individualized administration of vancomycin.

ABSTRACT
Vitiligo disease makes patients generally exist anxiety,depression,excessive stress response and other psychological characteristics,and the psychological harm caused by disease is more difficult to deal with than the harm caused by the disease itself.Due to the particularity of disease itself,the psychological pressure of general patients is greater than other disease and the psychological problems are more serious.Therefore,when the vitiligo patients seek medical advice,we should pay attention to more respects for patients,protect the privacy of patients;strengthen the emotional reaction between doctors and patients;make good use of psychological function;and promote the establishment of a good doctor-patient relationship and realize the benign interaction of doctor-patient relationship to make the condition of vitiligo patient gradually improved,and finally return to health.
ABSTRACT
Objective To study the apoptosis of human colorectal cancer HT-29 cells induced by Aralia elata Seem leaf total saponin (ETS) and its effects on the expression of relevant proteins. Methods MTT assay was used to detect the proliferation of human colorectal cancer HT-29 cells cultivated with different concentrations (6.25, 12.5, 25, 50, 100, 200 mg/kg) of ETS. Hoechst33258 staining and laser confocal imaging were used to detect the apoptotic cells. Morphological changes were observed. The expressions of Bcl-2 and Bax were detected by immuno-histochemistry. Results ETS could induce apoptosis of HT-29 cells and apoptosis was in a dose-dependent manner in a certain range. ETS could decrease the expression of Bcl-2 and increase the expression of Bax in HT-29 cells (P<0.05, P<0.01), showing a significant dose-effect relationship. Conclusion ETS can induce the apoptosis of HT-29 cells, and the mechanism may be related to reducing the expression of Bcl-2 and increasing the expression of Bax.
