Objective To develop a postoperative precision nursing program for children with obstructive sleep apnea-hypopnea syndrome(OSAHS),so as to provide references for the improvement of nursing quality for children with OSAHS.Methods Literature in precision nursing for children with OSAHS was systematically reviewed and summarised based on precision nursing theory and a postoperative precision nursing program was drafted.Using the Delphi's Method,two rounds of expert consultation were conducted and the postoperative precision nursing program for children with OSAHS was revised and finalised.Results The response rates of the two rounds of expert consultation were 100.00%with the expert authority coefficient of 0.875.The Kendall coefficient of concordance(W)of levels 1,2 and 3 indices in the second round of expert consultation were 0.289,0.203,0.187,respectively(all P<0.01).The importance score of each inclicator ranged from 4.50～4.94.The coefficient of variations for the three-level indices ranged from 0.05 to 0.21.The finalised program composed 8 level-1 indices(postoperative position assessment,intervention,prevention and care of bleeding,maintaining postoperative airway patency,postoperative nausea and vomiting care,postoperative pain assessment and care,dietary care,complication prevention and care,discharge guidance),16 level-2 indices,and 22 level-3 indices.Conclusion The postoperative precision nursing program for the children with OSAHS is scientific,innovative and applicable.It provides clinical references for nursing of the children with OSAHS.

Objective:To conduct evidence synthesis on disease communication between parents and their minor children from the perspective of parents with cancer, so as to provide information for clinical healthcare providers to deliver improved health education to patients and their children.Methods:Computer retrieval was implemented in PubMed, CINAHL, Embase, Web of Science, PsycINFO, Cochrane Library, ProQuest, China National Knowledge Infrastructure, and Wanfang Data. The search period was from January 1, 2000 to March 6, 2025. The literature was assessed according to the Joanna Briggs Institute (JBI) Center for Evidence-Based Health Care Quality Assessment Criteria for Qualitative Research. The JBI aggregative integration method was employed for the Meta-synthesis.Results:A total of nine articles were included. Thirty-two results were extracted, divided into ten categories, and integrated into five results, namely willingness to communicate illness, factors influencing communicating willingness, disease communication strategies, supporting children's coping, and perceptions of illness information.Conclusions:Disease communication between cancer parents and their minor children is influenced by multiple factors and exhibits complex diversity. Healthcare providers should fully understand and accurately recognize the distinct approaches of parents with cancer, offering guidance, advice, and encouragement whenever possible, and should dynamically provide timely medical support and assistance tailored to the evolving needs of patients throughout different stages of their disease treatment.

Objective By simulating the etiology of abnormal uterine bleeding-ovulatory dysfunction(AUB-O)and establishing a rat model of abnormal uterine bleeding(AUB),this study aims to provide an experimental platform for investigating pathological mechanisms and developing therapeutic drugs for AUB.Methods After acclimation,24 adult(10-week-old)female SD rats were randomly divided into a normal control group(6 rats)and a model group(18 rats).The normal control group was housed in a barrier environment,while the model group underwent bilateral ovariectomy via dorsal approach in the same environment and rested for one week before starting to receive modeling drugs.In the model group,from Days 1 to 3 of modeling,each rat received a daily subcutaneous injection of 0.5 mg estradiol into the dorsal region.From Days 4 to 7,a daily subcutaneous injection of 5.0 mg progesterone was administered.On Day 6,rats received bilateral injections of 0.5 mL soybean oil per uterine cavity(total 1.0 mL)via the same dorsal surgical incision.On Day 8,mifepristone(10 mg/kg)was administered via oral gavage.The estrous cycle stage and its dynamic changes were continuously monitored during modeling.Uterine bleeding was recorded during the 48-hour observation period post-modeling.Serum and uterine tissue samples were collected from the model group at 0,12,24,36,and 48 h after mifepristone administration,while the normal control group was sampled at 36 h.The samples were subjected to HE staining,serum sex hormone ELISA,immunohistochemistry,TUNEL apoptosis staining,Western blotting,transcriptome sequencing,and bioinformatics analysis for comprehensive evaluation of the AUB rat model.Results The AUB rats exhibited uterine bleeding,endometrial detachment and injury,incomplete uterine restoration,inflammatory cell infiltration in the endometrium,enhanced tissue apoptosis,and structural damage of the stroma,glands,and vasculature.Compared with the normal control group,the levels of serum follicle-stimulating hormone(FSH),estradiol,and luteinizing hormone(LH)were significantly increased in the AUB rats(P＜0.05).The vascular density of the endometrium was significantly reduced(P＜0.05).The expression of vascular endothelial growth factor(VEGF)was qualitatively observed to be markedly enhanced at the site of endometrial detachment but significantly decreased around the stromal blood vessels(P＜0.01).Matrix metalloproteinase-9(MMP-9)expression was qualitatively observed to be strongly upregulated at the site of endometrial injury but significantly reduced in the non-detached stroma and glands(P＜0.01).Endometrial stromal cell apoptosis was significantly enhanced(P＜0.01).The expression levels of fibroblast growth factor 2(FGF2)and endothelin-1(ET-1)in uterine tissues were significantly decreased(P＜0.05).After comparing the transcriptome sequencing results of uterine tissues between AUB and normal rats,a total of 4 723 differentially expressed genes were identified,including 2 191 up-regulated genes and 2 532 down-regulated genes.KEGG enrichment analysis revealed that these differentially expressed genes were significantly enriched in pathways related to inflammation,immune apoptosis,cell signal transduction,proliferation and differentiation,and muscle contraction,among others.Conclusion An AUB rat model can be successfully established using a sequential administration protocol of estrogen,progesterone,and mifepristone to simulate the etiology of AUB-O.In this model,endometrial injury is associated with inflammation and apoptosis,with pathological manifestations influenced by abnormal vasoconstriction and impaired endometrial regeneration.This rat model closely recapitulates pathological characteristics of non-structural AUB observed in clinical practice,making it a validated experimental platform for exploring the pathological mechanisms and therapeutic interventions of non-structural AUB.

Jiegengtang is a basic formula for treating sore throat and cough. By means of bibliometrics， this study conducted a textual research and analysis on the key information such as formula origin， decocting methods， and clinical application of Jiegengtang. After the research， it can be seen that Jiegengtang is firstly contained in Treatise on Febrile and Miscellaneous Disease， which is also known as Ganjietang， and it has been inherited and innovated by medical practitioners of various dynasties in later times. The origins of Chinese medicines in this formula is basically clear， Jiegeng is the dried roots of Platycodon grandiflorum， Gancao is the dried roots and rhizomes of Glycyrrhiza uralensis， the two medicines are selected raw products. The dosage is 27.60 g of Glycyrrhizae Radix et Rhizoma and 13.80 g of Platycodonis Radix， decocted with 600 mL of water to 200 mL， taken warmly after meals， twice a day， 100 mL for each time. In ancient times， Jiegengtang was mainly used for treating Shaoyin-heat invasion syndrome， with cough and sore throat as its core symptoms. In modern clinical practice， Jiegengtang is mainly used for respiratory diseases such as pharyngitis， esophagitis， tonsillitis and lung abscess， especially for pharyngitis and lung abscess with remarkable efficacy. This paper can provide literature reference basis for the modern clinical application and new drug development of Jiegengtang.

[Objective] To conduct serological identification and molecular mechanism study on a ambiguous ABO blood group. [Methods] Standard serological techniques were used for the forward and reverse typing of ABO blood type. ABO gene coding and regulatory regions were analyzed by PCR after DNA extraction. Monoclonal sequencing was used to detect the haplotypes of the DNA sequence, and bioinformatics analysis was applied to predict the possible translation outcomes of the mutated DNA sequence. [Results] The sample’s red blood cells showed mixed field agglutination with anti-A, and the serum agglutinated with B cells, exhibiting serological characteristics of subtype A. Direct sequencing and monoclonal sequencing analysis of the ABO gene confirmed one allele as O02, the other had a c.27delC mutation compared with A102, which could cause the translation sequence to terminate prematurely at the 19th amino acids. Analysis and prediction suggested that the mutation might affect the function of the transferase through mechanisms such as shifting the initiation codon, altering the reading frame and affecting the splice sites. [Conclusion] This case is a rare A subtype caused by the c.27delC variation, and the impact on the glycosyltransferase may involve multiple mechanisms, which require further research and exploration.

Objective To evaluate the clinical efficacy of electroacupuncture at acupoints distributed on conception vessel(CV)and governor vessel(GV)in treating ischemic stroke(AIS)complicated with dysphagia and explore its potential mechanism.Methods A total of 120 patients diagnosed with AIS complicated with dysphagia at Hangzhou TCM Hospital Affiliated to Zhejiang Chinese Medical University from December 2020 to December 2023 were enrolled and randomly divided into an observation group and a control group,with 60 patients per group.The control group received conventional swallowing training,while the observation group received additional electroacupuncture at acupoints distributed on CV and GV.The treatment lasted for 4 weeks.After 1 month of treatment,clinical efficacy was assessed,and the changes in Standardized Swallowing Assessment(SSA)scores,National Institutes of Health Stroke Scale(NIHSS)scores,hyolaryngeal mobility(thyroid cartilage anterior/superior displacement,hyoid bone anterior/superior displacement),and KubotaWater Swallowing Test scores were observed.Cerebral microcirculation parameters and the Chinese version of the Eating/Drinking Quality of Life(EDQoL)questionnaire were also compared.Safety and adverse events were evaluated.Results(1)The total effective rate in the observation group was 95.00%(57/60),compared to 76.67%(46/60)in the control group,demonstrating statistically superior therapeutic efficacy in the observation group(P＜0.05).(2)After treatment,both groups showed significant improvements in SSA scores and NIHSS scores(P＜0.05),with the observation group exhibiting markedly better enhancement in both SSA and NIHSS scores compared to the control group,showing statistically significant differences(P＜0.05).(3)After intervention,significant improvements were observed in anterior displacement of thyroid cartilage,superior displacement of thyroid cartilage,anterior displacement of hyoid bone,and superior displacement of hyoid bone in both groups(P＜0.05).The observation group outperformed the control group in all these laryngeal kinematic parameters with statistically significant differences(P＜0.05).(4)Both groups demonstrated significant improvement in Kubota Water Swallowing Test scores after treatment(P＜0.05),with the observation group displaying statistically greater improvement than the control group(P＜0.05).(5)Cerebral arterial parameters including peak systolic velocity(Vs),mean velocity(Vm),and resistance index(RI)were significantly improved in both groups after treatment(P＜0.05).The observation group showed superior enhancement in these cerebrovascular hemodynamic indices compared to the control group(P＜0.05).(6)Significant improvements in EDQoL scores were observed in both groups after treatment(P＜0.05),with the observation group achieving statistically greater improvement than the control group(P＜0.05).(7)The total incidence of adverse reactions was 1.67%(1/60)in the observation group versus 11.67%(7/60)in the control group,indicating a statistically significant lower adverse event rate in the observation group(P＜0.05).Conclusion Electroacupuncture at acupoints distributed on CV and GV effectively alleviates dysphagia and neurological impairment,improves hyolaryngeal mobility and cerebral microcirculation,enhances quality of life,and reduces adverse events such as aspiration pneumonia in AIS patients complicated with dysphagia.
