Background: Hierarchical management of sports risk is highly critical to ensure the safety of sports rehabilitation. Early identification, timely prevention and control of sports-related risk factors, and enhanced supervision and guidance can provide a basis for the formulation of sports programmes and the setting of sports monitoring levels., Objective: This study aimed to retrieve, evaluate, and integrate evidence for the stratified management of motor risk in patients with a cardiac implantable electronic device (CIED)., Methods: We searched for evidence according to the "6S" model of evidence-based resources. CNKI, VIP, Wanfang Data, CBM, PubMed, Cochrane Iibrary, CINAHL, EMbase, Web of Science, BMJ Best Practice, Up To Date, and International Guidelines Collaboration Network were searched from inception to February 2024. To search for evidence on stratified management of motor risk in patients with CIEDs, this research includes guidelines, systematic reviews, meta-analyses, expert consensus, clinical decision-making, and randomized controlled trials. After methodological quality evaluation, the evidence was extracted and summarized accordingly., Results: According to the inclusion and exclusion criteria, 16 pieces of evidence were screened, including 5 guidelines, 1 clinical decision-making, 5 systematic reviews, 4 expert consensus, and 1 randomized controlled trial. After reading, extracting, and categorizing, 34 pieces of evidence in 4 areas were identified, namely, screening and assessment of exercise risk in CIEDs, exercise monitoring, implementation of exercise prescriptions, and prevention and management of exercise-related risks., Conclusions: This study provides the best evidence for the prevention and management of exercise risk in patients with CIEDs, clarifies the role of nurses in evaluating, monitoring, and educating patients undergoing motor rehabilitation, and provides a basis for the formulation of clinically feasible rehabilitation programs., Systematic Review Registration: PROSPERO, identifier (CRD2024509622)., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2024 Di, Huang, Huang, Li, Gao and Bai.)

Objective: To investigate the influences of staphylococcus aureus in planktonic and biofilm forms on the expression of lysozyme, SLPI and gp340 in the human sinonasal explant model., Method: Mucosa samples from ethmoid sinus were collected from ten patients of cerebrospinal fluid leak and were cultured with and without S. aureus biofilms and planktonic cells. After the infection, the explant model was confirmed by CLSM, and the secretion of lysozyme, SLPI and gp340 was detected by enzyme-linked immunosorbent assay (ELISA) at 8, 16, and 24 h after S. aureus challenge. Expressions of lysozyme, SLPI and gp340 in mRNA and protein levels after 24 h S. aureus challenge were detected using RT-PCR, immunohistochemistry and Western bolt assay respectively., Result: The secretion of lysozyme, SLPI and gp340 in the explant model was observed with a trend to increase in a time-dependent manner. At 8 and 16 h after S. aureus challenge, the secretion of lysozyme, SLPI and gp340 in biofilms group was significantly higher than these in planktonic cells group and control group (P<0. 05). S. aureus biofilms enhanced the mRNA expressions of lysozyme, SLPI and gp340 significantly compared with planktonic cells and controls, and the mRNA expressions in the explant model challenged by planktonic cells were significantly higher than controls (P < 0.05). Although the Western bolt assay showed no differences between the lysozyme expression in the planktonic cells group and control group (P > 0.05), the biofilms enhanced the expressions of lysozyme, SLPI and gp340 significantly compared with planktonic cells and controls (P < 0.05)., Conclusion: S. aureus biofilm induced the expressions of lysozyme, SLPI and gp340 to a higher level than planktonic cells, indicating that S. aureus biofilm was an influencing factor on the innate immune system.

Objective: To investigate the main allergens in patients with allergic rhinitis in Zhengzhou district., Methods: Twenty standardization allergens were used to perform skin prick test in 1 139 patients with allergic rhinitis. The samples were divided into four groups according to the age of the patients. The distributions of different allergens in the four groups were analyzed., Results: The top five inhaled allergens were dermatophagoides farina (920 cases, 80.8%), dermatophagoides pteronyssinus (870 cases, 76.4%), cat hair (517 cases, 45.4%), herbs (397 cases, 34.9%) and poaceae (353 cases, 31.0%); the top five ingestive ones were shrimp (143 cases, 12.6%), peanut (66 cases, 5.8%), egg (56 cases, 4.9%), carp (51 cases, 4.5%) and meat (48 cases, 4.2%). The distribution of allergens was different among the different age groups., Conclusion: Dust mites, cat hair, herbs and poaceae were the most common allergens in Zhengzhou district.

MicroRNA has proved to be low expression in many tumor cells. In addition, it was also proved that as a kind of cancer suppressor gene, miR-199a-3p in miRNA can affect the growth and invasion ability of tumor cells. This paper aims to discuss the effect of miRNA to osteosarcoma cell. It used synthetic mature miR-199a-3p sequence simulants to transfect osteosarcoma cell and took negative contrast sequence (NC mimics) transfection cell as negative contrast. After transfection, qRT-PCR was applied to detect the expression quantity of miR-199a-3p in every group. Western blot method was applied to detect the expression level of MCL-(1) protein and shear situation of PARP in groups of cells. Flow cytometry was used for detecting apoptosis rate of cells and the experimental result was made a statistical analysis. The result shows that in cells from experimental group of transfection miR-199a-3p sequence simulants, expression quantity of mi-R-199a-3p significantly increased while MCL⁻¹ protein expression decreased compared to control group. In addition, shear level of PARP protein and apoptosis rate of cells increased. The differences all had statistical significance (P<0.05). It was concluded that miR-199a-3p can effectively promote the apoptosis rate of osteosarcoma cells.
