Objective:To retrospectively analyze and compare the clinical effects of rigid neuroendoscopic hematoma removal and drilling irrigation drainage in the treatment of chronic subdural hematomas with mixed density on head CT, and explore the appropriate surgical methods for chronic subdural hematomas with mixed density.Methods:A retrospective case-control study was conducted to analyze the clinical data of 80 patients with CSDH with mixed density CT findings admitted to the Department of Neurosurgery of Guizhou Medical University Affiliated Hospital from January 2021 to November 2023. There were 57 males and 23 females. According to the surgical method, patients were divided into endoscopic group ( n=36) and drilling group ( n=44). Patients in the endoscopic group underwent hard neuroendoscopic hematoma removal surgery, while patients in the drilling group underwent drilling flushing and drainage surgery. Compared the surgical time, drainage time, hematoma clearance rate, length of hospital stay, markwalder neurological function grading, and activities of daily living (ADL) score between two groups 30 days after surgery. Followed up for 3 months to record the recurrence situation.Measurement data with a normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for inter-group comparison. Measurement data with a non-normal distribution were expressed as M( Q1, Q3), and rank sum test was used for inter-group comparison. Chi-square test or Fisher′s exact test was used for inter-group comparison of count data. Rank sum test was used for inter-group comparison of ordinal data. Results:The operation time, postoperative drainage time, 24-hour hematoma clearance rate, midline deviation distance and hospital stay in the endoscopic group respectively were (77.50±8.15) min, 1.00(1.00, 2, 00) d, (95.00±2.66)%, 1.00(0.00, 2.00) mm, (9.47±2.52) d. The drilling group were (44.77±6.56) min, 3.00(2.25, 3.00) d, (87.86±3.43)%, 3.00(2.00, 3.00) mm, (11.84±3.28) d, the difference was statistically significant between the two groups ( P<0.05). Comparison of long-term efficacy in the endoscopic group, the hematoma clearance rate at 30 days after operation, the ADL score at 30 days after operation, and the number of recurrence cases at 3 months after operation respectively were 99.00(97.25, 100.00)%, (88.06±7.86) points, and 1 case. The drilling group were 93.50(91.25, 95.75)%, (83.29±9.58) points and 10 cases, with statistical difference between the two groups( P<0.05). 30 day postoperative Markwalder neurological functional grading, there were 27 cases grades 0, 9 cases of grade I, and 0 cases of grade II in endoscopic surgery. In the drilling group, there were 24 cases, 15 cases, and 5 cases, respectively. The difference between the two groups was statistically significant ( P<0.05). Conclusions:Compared with drilling and drainage irrigation surgery, neuroendoscopic treatment of mixed density chronic subdural hematoma takes a relatively long time, but the hematoma clearance rate is higher, the hospitalization time is shorter, the postoperative recovery is faster and the recurrence rate is lower. Neuroendoscopic therapy has unique advantages and may be more suitable for the treatment of mixed density CSDH.

Objective To analyze and clarify the concept of family communication collective efficacy in hospitalized patients.Methods A systematic search was conducted in databases including China National Knowledge Infrastructure(CNKI),VIP Database,WanFang Database,PubMed Database and Web of Science(WOS)for studies related to family communication efficacy.The search timeframe spanned from the inception of each database to December 2024.Rodgers'evolutionary concept analysis method was applied to analyze the retrieved literature.Results A total of 40 articles were included.The analysis shows that the evolution process of the concept of family collective communication efficacy in hospitalized patients was introduced,encompassing the evolution of the family communication concept and the intersection and integration of family systems theory and collective efficacy theory.Family communication collective efficacy in hospitalized patients was characterized by four attributes:shared beliefs,emotional support,role allocation and coordination,and an integrated communication system.Its antecedents included factors such as sources of efficacy information,family member characteristics,and family team characteristics.The consequences were observed at three levels:individual,family,and healthcare system,including manifesting as bidirectional influences on individual health outcomes,family functioning,and healthcare quality improvement.Conclusions The core attributes of family communication collective efficacy in hospitalized patients were clarified through concept analysis.In the future,localized assessment tools should be developed based on these attributes to facilitate the implementation and evaluation of interventions aimed at enhancing family communication collective efficacy.

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.

AIM:To investigate whether melatonin can ameliorate acute myocardial infarction(AMI)by in-hibiting ferroptosis.METHODS:H9C2 cells were cultured in AnaeroPack system with low sugar and serum-free medium for 10 h to construct a cell model of AMI.Then cells were treated with melatonin and ferroptosis inducer erastin.The cell activity,reactive oxygen species(ROS),lipid peroxidation,mitochondrial membrane potential(MMP),and ferroptosis related protein expression were detected.A rat model of AMI induced by isoprenaline(ISO)injection was established to evaluate the effects of melatonin,in which the myocardial infarction size,cardiac injury,pathological changes,oxidative stress,iron ion and ferroptosis related protein expression were examined.RESULTS:Melatonin decreased the oxidative stress,lipid peroxidation and expression of ferroptosis protein in cardiomyocytes induced by hypoxia,but these effects could be impeded by the ferroptosis inducer erastin.Furthermore,in vivo experiments,we also found that melatonin im-proved the myocardial infarction size,cardiac injury,pathological changes,oxidative stress,and alleviated iron ion accu-mulation and ferroptosis.CONCLUSION:The cardioprotective effects of melatonin in AMI are associated with the inhi-bition of ferroptosis.

Objective:To explore the longitudinal trajectory of sleep disorders and their influencing factors in newly diagnosed breast cancer patients, and provide theoretical basis for formulating intervention measures to improve sleep quality of breast cancer patients.Methods:A longitudinal study was conducted using convenience sampling to select newly diagnosed breast cancer patients from Shandong Provincial Third Hospital and Shandong First Medical University Affiliated Provincial Hospital from April 2023 to June 2024. General information questionnaires, the Pittsburgh Sleep Quality Index (PSQI), the Concerns About Recurrence Scale (CARS), and the Distress Disclosure Index (DDI) were used for the survey. The Kruskal-Wallis H test and generalized estimating equation models were used to examine sleep disorders and their influencing factors. Results:A total of 473 valid questionnaires were collected. Among the 473 newly diagnosed breast cancer patients, 435 were female and 38 were male, aged (49.5 ± 11.0) years old. The CARS score at admission was (3.00 ± 1.12) points, with concerns about death (0.71 ± 0.67) points and concerns about female characteristics (0.81 ± 0.72) points. The DDI score at admission was (27.00 ± 10.03) points. The PSQI scores at admission, discharge, and one month after discharge were (15.34 ± 3.05), (12.12 ± 3.01), and (10.13 ± 1.78) points, respectively, the difference was statistically significant ( H =33.19, P<0.05). The PSQI scores at these three time points were positively correlated with the CARS score and concerns about death and female characteristics ( r values were 0.42-0.79, all P<0.05), and negatively correlated with the DDI score ( r =-0.41, -0.37, -0.31, all P<0.05). The generalized estimating equation model showed that female gender ( β=1.35, 95% CI 0.27-2.30), education level of junior high school or below ( β=1.89, 95% CI 0.24-3.19), severe pain ( β=1.72, 95% CI 0.32-3.12), moderate pain ( β=2.51, 95% CI 0.37-4.66), invasive special cancer ( β=2.57, 95% CI 1.67-4.07), invasive non-special cancer ( β=2.11, 95% CI 1.98-3.12), partial understanding of the condition ( β=1.91, 95% CI 1.23-3.01), concerns about death ( β=1.61, 95% CI 0.17-2.78), and concerns about femininity ( β=1.34, 95% CI 0.37-2.15) positively predicted the sleep quality index in newly diagnosed breast cancer patients (all P<0.05). Non-invasive cancer ( β=-3.82, 95% CI -6.79--3.36), lack of understanding of the condition ( β=-3.96, 95% CI -7.09--4.62), and DDI score ( β=-1.45, 95% CI -2.14--0.15) negatively predicted the sleep quality index (all P<0.05). Conclusions:The overall sleep quality of newly diagnosed breast cancer patients is low, with the lowest at admission and gradual improvement at discharge and one month after discharge. Medical staff should pay attention to high-risk patients who are female, have lower education levels, higher pain scores, poorer pathological types, and partial understanding of their condition.

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.

Insufficient alveolar bone thickness increases the risk of periodontal dehiscence and fenestration, especially in orthodontic tooth movement. Abaloparatide (ABL), a synthetic analog of human PTHrP (1-34) and a clinical medication for treating osteoporosis, has recently demonstrated its potential in enhancing craniofacial bone formation. Herein, we show that intraoral submucosal injection of ABL, when combined with mechanical force, promotes in situ alveolar bone thickening. The newly formed bone is primarily located outside the original compact bone, implying its origin from the periosteum. RNA sequencing of the alveolar bone tissue revealed that the focal adhesion (FA) pathway potentially mediates this bioprocess. Local injection of ABL alone enhances cell proliferation, collagen synthesis, and phosphorylation of focal adhesion kinase (FAK) in the alveolar periosteum; when ABL is combined with mechanical force, the FAK expression is upregulated, in line with the accomplishment of the ossification. In vitro, ABL enhances proliferation, migration, and FAK phosphorylation in periosteal stem cells. Furthermore, the pro-osteogenic effects of ABL on alveolar bone are entirely blocked when FAK activity is inhibited by a specific inhibitor. In summary, abaloparatide combined with mechanical force promotes alveolar bone formation via FAK-mediated periosteal osteogenesis. Thus, we have introduced a promising therapeutic approach for drug-induced in situ alveolar bone augmentation, which may prevent or repair the detrimental periodontal dehiscence, holding significant potential in dentistry.

Objective To investigate the effects of electroacupuncture(EA)at"Baihui(GV 20),""Pishu(BL 20),"and"Zusanli(ST 36)"on the learning and memory functions of rats with Alzheimer's disease(AD)induced by Aβ1-42.Additionally,the mechanism of EA in treating AD was explored from the perspective of the inflammatory cascade mediated by the NF-κ B/NLRP3/Caspase-1 signaling pathway.Methods A rat model of Alzheimer's disease was established by bilateral injection of Aβ1-42 solution into the C1 region of the hippocampus.According to the random number table method,32 male SPF-grade rats were divided into four groups(n=8 per group):a sham-operated group,a model group,an electroacupuncture(EA)group,and a Western medicine group(donepezil hydrochloride).The EA group received electroacupuncture at the"Baihui","Pishu",and"Zusanli"acu-points;the Western medicine group received donepezil hydrochloride via gavage.After the treatment period,Morris water maze experiments were conducted to evaluate learning and memory abilities.Hematoxylin and eosin(HE)staining was used to examine morphological changes in hippocampal tissues.Enzyme-linked immunosorbent assay(ELISA)was employed to measure serum levels of TNF-α and IL-1β.Western blotting and immunofluorescence staining were utilized to assess the co-expression levels of NF-κB p65,NLRP3,and Caspase-1 proteins in the hippocampal region.Results Compared with the sham-operated group,rats in the post-modeling group exhibited significantly prolonged escape latency(P<0.05),reduced crossings of the original platform location,and decreased time spent in the target quadrant(P<0.05).Additionally,nuclear morphology was altered,neurons surrounding the hippocampus displayed necrosis,vacuolar degeneration,and chromatin marginalization.Serum levels of TNF-α and IL-1β were elevated(P<0.05),and protein expression levels as well as fluorescent positivity for NF-κB p65,NLRP3,and caspase-1 in the hippocampus were increased(P<0.05).Compared with the model group,rats in both the EA and Western medicine groups showed a trend toward shorter escape latency(P<0.05),increased crossings of the original platform location and time spent in the target quadrant(P<0.05).Cell structures were largely intact,with only a few nuclei showing slight irregularities and some chromatin accumulation at the edges.Serum levels of TNF-α and IL-1β were reduced(P<0.05),and protein expression levels and fluorescence positivity for NF-κB p65,NLRP3,and caspase-1 in the hippocampus were also decreased(P<0.05).Conclusion EA enhances the learning and memory capabilities of AD rats,potentially by downregulating the NF-κ B/NLRP3/Caspase-1+signaling+pathway and decreasing the release of neuroinflammatory factors,thereby alleviating cognitive dysfunction in AD rats.

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.
