To investigate the efficacy and assess the safety of transnasal nebulisation of budesonide in children with adenoid hypertrophy. Children with adenoid hypertrophy who attended the Children's Hospital of Zhejiang University School of Medicine between December 2021 and December 2022 were randomly assigned to budesonide high-dose group（Group A: budesonide 1 mg/dose + saline nasal rinse）, budesonide low-dose group（Group B: budesonide 0.5 mg/dose + saline nasal rinse）, and control group（Group C: saline nasal rinse）, and each group 20 children were collected separately, The efficacy and safety of transnasal nebulisation of budesonide in children with adenoid hypertrophy were assessed by comparing the symptomatic VAS scores, adenoidal nasopharyngeal lateral radiographs A/N values, nocturnal sleep oximetry（SaO2）, and the incidence of adverse events during the treatment period of 8-week in the three groups.

Research Advances on Stem Cell-Derived Extracellular Vesicles Promoting the Reconstruction of Alveolar Bone through RANKL/RANK/OPG Pathway.

Periodontal bone tissue defects and bone shortages are the most familiar and troublesome clinical problems in the oral cavity. Stem cell-derived extracellular vesicles (SC-EVs) have biological properties similar to their sources, and they could be a promising acellular therapy to assist with periodontal osteogenesis. In the course of alveolar bone remodeling, the RANKL/RANK/OPG signaling pathway is an important pathway involved in bone metabolism.

Technology development and cost analysis of multiple pollutant abatement for ultra-low emission coal-fired power plants in China.

The implementation of ultra-low emission (ULE) limits (SO: 35 mg/m, NOx: 50 mg/m, PM: 10 mg/m) promoted the development of flue gas treatment technologies in China. Pollutant control technology development for Chinese coal-fired power plants was summarized and an analysis of the applicability and cost of pollutant control technologies was conducted. Detailed data were collected from 30 ultra-low emission coal-fired units across China.

Advances in air pollution control for vessels in China.

Vessel emissions have contributed a great deal to air quality deterioration in China. Hence, the Chinese government has promulgated a series of stringent emission regulations. It is in this context that vessel emission control technology research is in full swing.

Is simultaneous cranioplasty with cerebrospinal fluid shunts implantation as safe as staged procedures?

Objective: The combination of cranioplasty and ventriculoperitoneal shunt is a therapeutic strategy for patients with hydrocephalus after decompressive craniectomy (DC). However, the efficacies of simultaneous vs. staged surgery in reducing postoperative complications have not been conclusively determined.

Comparison of the Value of Conventional Ultrasound and Contrast-Enhanced Ultrasound-Guided Puncture Biopsy in Different Sizes of Peripheral Pulmonary Lesions.

Objective: To compare the clinical value of contrast-enhanced ultrasound and conventional ultrasound-guided puncture biopsy in peripulmonary lesions of different sizes.

Materials And Methods: 110 patients with peripulmonary lesions were randomly divided into two groups: the conventional ultrasound-guided group and the contrast-enhanced ultrasound-guided group. The lesions in the two groups were further divided into two groups according to the size of the lesions, and the tissues taken after puncture biopsy were sent for pathological examination.

Neck and mediastinal hematoma caused by a foreign body in the esophagus with diagnostic difficulties: A case report.

Background: Esophageal foreign body (FB) is a common clinical emergency. Clinically, computed tomography (CT) scans are important in the diagnosis of FBs in the esophagus. Here, we report a case of esophageal perforation and cervical hematoma, caused by a FB, whose uniqueness made rapid diagnosis difficult.

Osteogenic peptides in periodontal ligament stem cell-containing three-dimensional bioscaffolds promote bone healing.

Bone tissue engineering shows great potential in bone regeneration; however, the lack of bone growth factors with high biocompatibility and efficiency is a major concern. Oligopeptides have drawn great attention due to their high biological efficacy, low toxicity, and low molecular weight. The oligopeptide SDSSD promotes the osteogenesis of human periodontal ligament stem cells (hPDLSCs) The SDSSD-modified three-dimensional (3D) bioscaffolds promote osteogenesis and bone formation in the subcutaneous pockets of BALB/c nude mice and facilitate bone healing .

Correlation between anxiety-depression symptoms and immune characteristics in inpatients with 2019 novel coronavirus in Wuhan, China.

Background: Coronavirus disease 2019 (COVID-19) is widely acknowledged as a severe traumatic event, and depression, anxiety, and psychological distress are common in diagnosed patients. However, the correlations of biological indicators with emotion are rarely reported. The primary objective of this study was to explore the dysfunction of immune-inflammatory characteristics in patients with depression-anxiety symptoms.

Effect of a Text Messaging-Based Educational Intervention on Cesarean Section Rates Among Pregnant Women in China: Quasirandomized Controlled Trial.

Background: Consensus exists that appropriate regional cesarean rates should not exceed 15% of births, but China's cesarean rate exceeds 50% in some areas, prompting numerous calls for its reduction. At present, China's 2016 two-child policy has heightened the implications of national cesarean section trends.

Objective: This study leveraged pervasive cellular phone access amongst Chinese citizens to test the effect of a low-cost and scalable prenatal advice program on cesarean section rates.

Bone-Targeted Extracellular Vesicles from Mesenchymal Stem Cells for Osteoporosis Therapy.

Background: Current drugs used for osteoporosis therapy show strong adverse effects. Stem cell-derived extracellular vesicles (EVs) provide another choice for osteoporosis therapy. Mouse mesenchymal stem cells (mMSCs)-derived EVs promote bone regeneration; however, their clinical application is limited due to non-specific tissue targeting.
