Chronic rhinosinusitis (CRS) represents a heterogeneous disorder primarily characterized by the persistent inflammation of the nasal cavity and paranasal sinuses. The subtype known as chronic rhinosinusitis with nasal polyposis (CRSwNP) is distinguished by a significantly elevated recurrence rate and augmented challenges in the management of nasal polyps. The pathogenesis underlying this subtype remains incompletely understood.

Drawing on the ecological systems theory, this study sought to investigate the mediating mechanism of peer attachment and the moderating mechanism of school climate that link parental autonomy granting to PIU. A two-wave longitudinal design was employed with a time interval of six months.

Background: Collision tumors involving the small intestine, specifically the combination of a hamartomatous tumor and a lipoma, are extremely rare. To our knowledge, no previous case report has described a collision tumor composed of two benign tumors of different origins in the small intestine.
Case Summary: Here, we present the case of an 82-year-old woman who presented with hemorrhagic shock and was found to have a mass measuring approximately 50 mm × 32 mm × 30 mm in the terminal ileum.

The development of transmucosal drug delivery systems is a practical requirement in oral clinical practice, and controlled sequential delivery of multiple drugs is usually required. On the basis of the previous successful construction of monolayer microneedles (MNs) for transmucosal drug delivery, we designed transmucosal double-layer sequential dissolving MNs using hyaluronic acid methacryloyl (HAMA), hyaluronic acid (HA), and polyvinyl pyrrolidone (PVP). MNs have the advantages of small size, easy operation, good strength, rapid dissolution, and one-time delivery of two drugs.

Dupilumab is a promising treatment for these patients, but its cost-effectiveness has not yet been compared with aspirin (acetylsalicyclic acid, or ASA) desensitization, a known and effective treatment. We aimed to compare the cost-effectiveness of ASA desensitization with dupilumab therapy for the treatment of CRSwNP in AERD.

Exposure to pre-operative radiation may put patients at an increased risk of skull base reconstructive failure. A systematic search identified studies which included patients receiving ventral skull base reconstruction in the setting of pre-operative radiation.

During the COVID-19 pandemic, it is essential for HCWs to recognize which procedures are potentially aerosolizing so that appropriate infection prevention precautions can be taken. The aim of this literature review was to identify potential AGMPs in Otolaryngology - Head and Neck Surgery and provide evidence-based recommendations.

First Nations community members decided on a whole school approach to facilitate PAX-GBG implementation, by offering intervention training to all staff members in their schools. Our objective is to gain a greater understanding of how this approach was viewed by school personnel, in order to improve implementation in remote and northern First Nations communities.

In market, the price of Apis cerana honey (ACH) is usually several times higher than that of Apis mellifera honey (AMH) due to the production limit, resulting in wide adulteration and counterfeiting of ACH by AMH. In the present study, we compared honeybee secretions in these two kinds of honey, and found significant differences in protein profiles and hydrocarbon components.

To gain insights into the molecular architecture underlying these caste differences, we compared the gene expression patterns of MGs from queens, queenright workers (WQRs) and queenless workers (WQLs) using high-throughput RNA-sequencing technology. In total, we identified 46 candidate genes associated with caste-specific biosynthesis of fatty acid pheromones in the MG, including members of cytochrome P450 (CYP450) family and genes involved in fatty acid β-oxidation and ω-oxidation.

This study evaluated the effectiveness of three immobilisation systems by assessing their set up deviations.
Methods: Patients were randomly assigned to one of the three immobilisation systems: (1) supine on head rest and base plate (HB); (2) supine with alpha cradle supporting the head and shoulder (AC); (3) supine with vacuum bag supporting the head and shoulder (VB).

Objective: To investigate the risk factors of prolonged intensive care unit (ICU) stay following coronary artery bypass grafting (CABG), and to provide a reference for effective control measure.
Methods: A retrospective study was conducted. All data of patients with post CABG admitted to the Department of Critical Care Medicine of the First People's Hospital in Yichang from January 2008 to January 2012 were retrospectively analyzed.

Objective: To investigate the risk factors of nosocomial infection caused by Pseudomonas aeruginosa in intensive care unit (ICU), in order to provide reference for an effective measure of infection control.
Methods: A retrospective study of cases of Pseudomonas aeruginosa infection occurring in ICU was made with multivariable Logistic regression analysis. The clinical data of 1 950 cases admitted from January 2002 to December 2006 were found to have nosocomial infection caused by Pseudomonas aeruginosa were analyzed in order to identify its independent risk factors.
Objective: To compare clinical outcome of intracytoplasmic sperm injection (ICSI) cycle by using fresh and cryopreserved-thawed testicular and epididymal spermatozoa in azoospermic patients.
Methods: Between September 2006 and May 2007, 208 azoospermic patients underwent in vitro fertilization (IVF) were treated in Center of Reproductive Medicine, Peking University Third Hospital. Those couples were divided into two groups based on their wishes, including 171 cases in fresh group and 37 cases in cryopreserved-thawed group.
Background & Objective: Intensity-modulated radiotherapy (IMRT) may help to diminish radiation-induced normal tissue damage and improve quality of life of nasopharyngeal carcinoma (NPC) patients. However, highly conformal treatment techniques commonly establish steep dose gradients between tumor and normal tissues, therefore, daily setup variations can significantly compromise the ultimate precision of idealized IMRT delivery. This study was to investigate the setup accuracy of thermoplastic masks used for immobilizing NPC patients treated by simultaneous integrated boost IMRT, and to determine adequate margins to account for those uncertainties.

In the present study, we investigated the possibility of cloning cat embryos using rabbit oocytes, and compared the developmental capacity; the timing of embryogenesis of the cat-rabbit cloned embryos with that of the cat-cat or the rabbit-rabbit cloned embryos. When cultured in M199, the rate of blastocyst formation of the cat-rabbit embryos was 6.

The use of the monkey model for biomedical research can avoid legal, ethical, and experimental limitations encountered in a clinical situation. We describe in this study the in vitro development of macaca-rabbit embryos produced by fusing macaca fibroblasts with enucleated rabbit oocytes and examine the fate of mitochondrial DNA in these embryos.

These cells include 2-cell embryonic blastomeres, KMW embryonic stem (ES) cells, fetal fibroblast, ear fibroblast, tail tip fibroblast, sertoil cells and spermatogonia. Meanwhile, we compared the effects of passage numbers of fetal fibroblast cells on developmental competency after nuclear transfer.

In order to observe whether these interspecies cloned embryos can implant in the uterus of an animal other than the panda, we transferred approximately 2300 panda-rabbit cloned embryos into 100 synchronized rabbit recipients, and none became pregnant. In another approach, we cotransferred both panda-rabbit and cat-rabbit interspecies cloned embryos into the oviducts of 21 cat recipients.
