Natural Products-Based Inhaled Formulations for Treating Pulmonary Diseases.

Given the unique physiological and pathological characteristics of the lung, the direct, inhalable route is more conducive to pulmonary drug delivery and disease control than traditional systemic drug delivery, significantly circumventing drug loss, off-target effects, systemic and organ toxicity, etc., and is widely regarded as the preferred regimen for pulmonary drug delivery. However, very few lung diseases are currently treated with the preferred inhaled formulations, such as asthma, chronic obstructive pulmonary disease and pulmonary hypertension.

Application value of EV/EV71/CA16-SAT detection in children with hand-foot-mouth disease.

The objective of this work was to explore the application value of a new type of fluorescent nucleic acid isothermal amplification (SAT) to detect EV/EV71/CA16-SAT in children with hand-foot-mouth disease (HFMD). For this purpose, from March 2017 to September 2019, Chengdu Children's Specialized Hospital collected throat swabs from children with clinical manifestations of hand, foot and mouth disease, and used SAT technology to screen and detect universal enterovirus (EV) nucleic acid (There were 1860 children with EV-RNA) positive. Patients who are EV-RNA positive at any time: first use the same throat swab specimen to detect EV71/CA16-RNA; secondly, collect venous blood and use the colloidal gold method to detect IgM antibodies in EV71/CA16 serum.

[The Application of RNA-Sequencing in Pediatric B-Cell Acute Lymphoblastic Leukemia].

Objective: To explore the molecular genetic characteristics of children with B-cell acute lymphoblastic leukemia (B-ALL) and the application value of RNA-sequencing (RNA-seq).

Methods: The clinical and laboratory examination data of newly diagnosed B-ALL children who were given treatment in the Department of Hematology, Children's Hospital of Chongqing Medical University from May 2015 to April 2020 were collected and analyzed. All children were confirmed by bone marrow morphology, histochemical staining and flow cytometry, and the karyotype analysis, FISH, RT-PCR and RNA-seq detection were conducted.

Diagnosis accuracy of the miR-200 family tumor marker series in ovarian cancer: a systematic review and meta-analysis.

Background: To evaluate the diagnosis value of the microRNA-200 family in ovarian cancer patients. However, there is much controversy regarding the diagnosis of miR-200. Therefore, it is necessary to use meta method to further confirm the significance of diagnosis role of the miR-200 family tumor marker series in ovarian cancer.

Deficiency of TRIM32 Impairs Motor Function and Purkinje Cells in Mid-Aged Mice.

Proper functioning of the cerebellum is crucial to motor balance and coordination in adult mammals. Purkinje cells (PCs), the sole output neurons of the cerebellar cortex, play essential roles in cerebellar motor function. Tripartite motif-containing protein 32 (TRIM32) is an E3 ubiquitin ligase that is involved in balance activities of neurogenesis in the subventricular zone of the mammalian brain and in the development of many nervous system diseases, such as Alzheimer's disease, autism spectrum disorder, attention deficit hyperactivity disorder.

Antibiotic Use Among Hospitalized Children and Neonates in China: Results From Quarterly Point Prevalence Surveys in 2019.

Antimicrobial resistance is a significant clinical problem in pediatric practice in China. Surveillance of antibiotic use is one of the cornerstones to assess the quality of antibiotic use and plan and assess the impact of antibiotic stewardship interventions. We carried out quarterly point prevalence surveys referring to WHO Methodology of Point Prevalence Survey in 16 Chinese general and children's hospitals in 2019 to assess antibiotic use in pediatric inpatients based on the WHO AWaRe metrics and to detect potential problem areas.
