Objective: To understand the current status and associated factors of sleep problems among preschool children in Hainan Province, so as to provide scientific evidence for improving sleep health in this population. Methods: From January 2021 to June 2022, a total of 4 105 preschool children aged 3-6 years from 62 kindergartens in Hainan Province were selected using stratified cluster random sampling method. Demographic information and lifestyle habits were collected through the Hainan Province Child Growth and Development Survey Questionnaire. The Children s Sleep Habits Questionnaire (CSHQ) was employed to assess sleep status. Unconditional binary Logistic regression model was applied to investigate the associated factors of sleep problems among preschool children. Results: The overall CSHQ score for children was 58.03±18.84, with 80.95% of preschool children exhibiting sleep related issues. The top three most prevalent sleep problem domains were bedtime resistance (72.42%), sleep anxiety ( 54.88 %), and parasomnias (38.86%). Logistic regression analysis revealed that higher family annual income ( OR=0.60, 95%CI = 0.45-0.79), higher maternal education level ( OR=0.53, 95%CI =0.32-0.89), regular or daily vitamin D supplementation ( OR=0.77, 95%CI =0.60-0.99), and fully self initiated eating behavior ( OR=0.71, 95%CI =0.59-0.85) were negatively related with children s sleep problems; in addition, screen exposure ( OR=1.27, 95%CI =1.06-1.51) and picky eating ( OR= 1.47 , 95%CI =1.21-1.78) were positively related to children s sleep problems (all P <0.05). Conclusion The high detection rate of sleep problems among preschool children in Hainan Province is multifactorially associated with family environment, dietary habits, and lifestyle behaviors.

Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare multi-system disease that presents significant diagnostic challenges due to its complexity and low incidence (White and Dubey, 2023). It affects males and females equally, though males may exhibit more active disease at diagnosis and often require more aggressive treatment (Liu et al., 2023). The hallmark features of EGPA include delayed-onset asthma, eosinophilia in tissues and blood, and vasculitis affecting small to medium-sized arteries (White and Dubey, 2023). EGPA falls under the category of antineutrophil cytoplasmic antibody (ANCA)‍-associated vasculitis (AAV), whereas only about half of EGPA patients test positive for ANCA (Khoury et al., 2023).

Objective A randomized controlled trial was conducted on colonoscopy inpatient and outpatients to compare the efficacy and safety of water exchange(WE)colonoscopy and CO2 convention insufflation colonoscopy in elderly patients.Methods 340 patients underwent fully sedated colonoscopy were randomly divided into two groups according to colonoscopy with either WE colonoscopy group(WE group)and CO2 insufflation colonoscopy group(CO2 group).The two groups were compared in terms of Boston bowel preparation scale(BBPS),withdrawal time,cecal intubation time,cecal intubation success rate,abdominal compression,willingness to repeat,polypdetectionrate(PDR),adenoma detection rate(ADR),and safety.Results The cecal intubation success rate was significantly higher in WE group(100.0%)compared with CO2 group(96.5%),the difference was statistically significant(P=0.013).The average cecal intubation time of WE group was(10.50±1.79)min,which was longer than that of CO2 group(7.55±1.50)min,and the difference was statistically significant(P<0.01).Comparison of withdrawal time and BBPS between the two groups,the differences were not statistically significant(P>0.05).The abdominal pressure rate was lower in WE group(5.9%)compared with CO2 group(13.5%),the difference was statistically significant(P=0.017).The rate of willingness to re-examination in the WE group was 98.2%,which was significantly higher than the 93.5%in the CO2 group.The PDR in WE group(80.6%)was higher than that in CO2 group(70.6%),the ADR in WE group(67.1%)was higher than that in CO2 group(50.6%),the differences were statistically significant(P<0.05).Multivariate Logistic regression analysis showed that WE group was an effective factor in improving ADR(O＾R=2.027,P<0.01).The overall adverse events were less than 3%,with no difference between the two groups(P=1.000).Conclusion The use of WE colonoscopy has a better improved efficacy in elderly patients,and safety should be ensured by individualized assessment of the patient's co-morbidities,bowel preparation tolerance,and willingness prior to the procedure.

Objective:To investigate the feasibility and safety of endoscopic surgery in the treatment of fibro-adipose vascular anomaly (FAVA).Methods:Clinical data of FAVA patients who underwent endoscopic treatment admitted to Xi’an International Medical Center Hospital from October 1, 2019 to April 1, 2024 were retrospectively analyzed, including gender, age of onset, age of diagnosis, lesion location, operation time, intraoperative blood loss, hospital stays, incision complications, etc. Before endoscopy, magnetic resonance imaging and ultrasound were routinely used to locate the lesion range, and the surgical position and Trocar location were selected according to different lesion sites.Descriptive statistical analysis was conducted using SPSS version 26.0.Results:40 cases of FAVA patients were admitted during the period, all of whom underwent endoscopic radical resection, including 15 males and 25 females. The age of onset was 8 (6, 12.5) years. The age of diagnosis was 11 (8, 22.5) years. There were 31 patients with stage Ⅰ and 9 patients with stage Ⅱ. 31 cases involved the calf, of which 21 involved the calf triceps (gastrocnemius, soleus) and 9 involved the thigh, of which 1 patient had lesions originating from the fascia around the sciatic neurovascular bundle. 11 cases (27.5%) were converted to open surgery. The operative time was 192.5 (107, 292.5) min. The intraoperative blood loss was 35 (10, 87.5) ml. The length of hospital stay for endoscopic surgery was 9 (7, 11) d. The postoperative follow-up time was 11.5 (3.5, 13.5) months. Of the 40 patients, 39 were cured completely without residual pain or joint movement disorder after operation. Postoperative dorsiflexion function of the ankle joint was mildly limited in one patient classified as stage Ⅱ. There was no incision complication and recurrence.Conclusion:For patients with stage Ⅰ and Ⅱ FAVA, endoscopic surgery has concealed incisions, indistinct scars, definite therapeutic effects and high safety.

Objective To observe the effects of electroacupuncture on RhoA/ROCK2 signaling pathway in cerebral cortex of mice with amyotrophic lateral sclerosis(ALS);To explore the mechanism of electroacupuncture in improving the motor function of ALS mice.Methods The male hSOD1G93A mice were divided into model group and electroacupuncture group,and wild-type male mice in the same litter were set as blank group,with 12 mice in each group.After the mice were 60 days old,"Baihui"and both side of"Tianzhu","Tianshu"were selected for electroacupuncture for 10 min per day,5 days of continuous treatment and 2 days off for 3 weeks.Rotating rod experiment and open field experiment were used to evaluate the motor function of mice,the damage of neurons in cerebral cortex was observed by Nissl staining,Western blot was used to detect the expressions of Tar DNA binding protein-43(TDP-43),tumor necrosis factor(TNF)-α,interleukin(IL)-1β,RhoA and ROCK2 protein in cerebral cortex.Immunofluorescence staining was used to detect the positive expressions of ion calcium binding adapter molecule 1(Iba-1)and glial fibrillary acidic protein(GFAP)in cerebral cortex.Results Compared with the blank group,the incubation period of rod turning and the total distance of open field movement in the model group were reduced(P<0.01),the neuron damage was obvious in the cerebral cortex,with Nissl body shrinkage and reduction in quantity(P<0.01),the relative expressions of TDP-43,TNF-α,IL-1β,RhoA and ROCK2 protein increased(P<0.01),and the positive expression of Iba-1 and GFAP increased(P<0.01).Compared with the model group,the incubation period of rod turning and the total distance of open field movement increased in electroacupuncture group(P<0.05),the damage of neuron in cerebral cortex was reduced,the number of Nissl bodies increased(P<0.05),the expressions of TDP-43,TNF-α,IL-1β,RhoA and ROCK2 decreased(P<0.05),and the positive expression of Iba-1 and GFAP reduced(P<0.05).Conclusion Electroacupuncture can improve motor function in ALS model mice,and the mechanism may be related to the inhibition of RhoA/ROCK2 signaling pathway activity and then relieve neuroinflammation.

Owing to the insidious onset and limited awareness of early screening,many patients with esophageal squamous cell carcinoma(ESCC)are diagnosed at an advanced stage.Immunochemotherapy is the current standard first-line treatment for advanced ESCC;however,survival outcomes remain suboptimal.Radiotherapy,with its precise local control and potential immunomodulatory effects,is anticipated to act synergistically with immunochemotherapy,offering a novel direction for overcoming survival limitations.This review systematically sum-marizes the progress in the use of radiotherapy as a first-line treatment for advanced ESCC and discusses the synergistic mechanisms,clinical applications,and challenges associated with its combination with immunochemotherapy.

Colorectal cancer(CRC)is one of the most prevalent gastrointestinal tumors;however,its pathogenesis is poorly understood.Therapeutic strategies for CRC vary according to molecular typing.Immune checkpoint inhibitors(ICIs)have shown significant efficacy in pa-tients with mismatch repair-deficient/microsatellite instability-high(dMMR/MSI-H)CRC.However,ICIs are less effective in patients with mis-match repair-proficient/microsatellite instability-low(pMMR/MSI-L).Intestinal flora have been found to enhance immunotherapy for CRC and ameliorate immunotherapy-related adverse effects by modulating immune responses through multiple mechanisms,particularly in pa-tients with pMMR/MSI-L CRC.This article reviews the key role of intestinal flora in regulating immunotherapy for CRC,discusses the pro-gress of related studies,and considers the clinical translational prospects of diet,probiotics,and fecal microbiota transplantation(FMT).

Nonunion of osteoporotic vertebral fractures (OVF), predominantly affecting the elderly, can lead to intractable pain, vertebral collapse, progressive kyphotic deformity, and neurological impairment, significantly compromising patients′ quality of life. There exists considerable debate on diagnosis and management of OVF, encompassing key issues such as clinical diagnosis and staging criteria for nonunion, surgical indications and procedure selection, and postoperative rehabilitation planning. Currently, there lacks standardized clinical guideline and expert consensus on the diagnosis and management of OVF nonunion in China. To address this gap, Minimally Invasive Surgery Group of Chinese Orthopedic Association, Osteoporosis Committee of Chinese Association of Orthopedic Surgeons, Prevention and Rehabilitation Committee for Osteoporosis of Chinese Association of Rehabilitation Medicine and Minimally Invasive Orthopedic Surgery Branch of China Association for Geriatric Care jointly organized domestic experts in spinal surgery, endocrinology, and rehabilitation to formulate the Clinical guideline for the diagnosis and treatment for nonunion of osteoporotic vertebral fractures ( version 2025), based on existing literature and clinical experience and adhering to principles of scientific rigor and practicality. The guideline provided 13 evidence-based recommendations encompassing diagnosis and treatment of OVF nonunion, aiming to standardize its clinical management.

OBJECTIVE: To observe the effects of "olfactory three needles" on cognition, learning and memory abilities, as well as hippocampal microglia (MG) phagocytic activity in vascular dementia (VD) rats, and explore the mechanisms of acupuncture in regulating MG activation and improving remyelination, so as to ameliorate VD. METHODS: Among 38 SD rats meeting experimental requirements, 9 rats were randomly assigned to a sham-operation group, and the remaining rats underwent permanent bilateral common carotid artery ligation to establish VD model. Eighteen successfully modeled rats were randomly divided into a model group and an electroacupuncture (EA) group, with 9 rats in each one. In the EA group, EA was performed at "olfactory three needles" ("Yintang" [GV24⁺] and bilateral "Yingxiang" [LI20]), at disperse-dense wave, the frequency of 2 Hz/15 Hz and the current intensity of 1 mA, for 15 min per intervention, once daily. One course was composed of 7 days, and 2 courses were required, with the interval of 2 days. The novel object recognition test was employed to assess the cognition of rats, and the Morris water maze was adopted to observe learning and memory abilities. Luxol fast blue (LFB) staining was performed to evaluate myelin sheath loss in the hippocampus, the Western blot was used to detect the protein expression of triggering receptor expressed on myeloid cells-2 (TREM2) and proteolipid protein (PLP) in the hippocampus; and the immunofluorescence staining was used to detect the positive expression of PLP, sex determining region Y-box 10 (SOX10), ionized calcium binding adaptor molecule 1 (Iba1)⁺ TREM2⁺ and Iba1⁺ lysosome-associated membrane protein 1 (LAMP1)⁺ in the hippocampus. RESULTS: Compared with the sham-operation group, the rats in the model group exhibited the prolonged escape latency on day 3 and 4 (P<0.05, P<0.01), the increase of the total distance traveling (P<0.01) and the decrease of the recognition index (RI) and platform crossing frequency (P<0.01). Compared with the model group, the rats in the EA group showed the shortened escape latency on day 3 and 4 (P<0.05), the decrease of total distance traveling (P<0.01) and the increase of RI and platform crossing frequency (P<0.05, P<0.01). When compared with the sham-operation group, the rats of the model group presented uneven staining, sparse arrangement of myelin sheath fibers, unclear contours, and prominent vacuole-like changes in the hippocampal CA1 region. When compared with the model group, the EA group showed more dense staining, the increase of myelin sheath fibers with more orderly alignment, and fewer vacuolar changes in the hippocampal CA1 region. Compared with the sham-operation group, the model group exhibited the increase of TREM2 protein expression and the decrease of PLP protein expression in the hippocampus (P<0.01), whereas the EA group showed the up-regulation of TREM2 and PLP protein expression when compared with the model group (P<0.01, P<0.05). The positive expression of the hippocampal PLP, SOX10, and Iba1⁺LAMP1⁺ in the model group was reduced in comparison with the sham-operation group (P<0.05, P<0.01), and the positive expression of Iba1⁺ TREM2⁺ was elevated (P<0.05). In the EA group, the positive expression of PLP, SOX10, Iba1⁺TREM2⁺, and Iba1⁺ LAMP1⁺ was higher compared with that in the model group (P<0.05, P<0.01). CONCLUSION "Olfactory three needles" can improve the learning and memory, and cognitive functions of VD rats, and its mechanism may be associated with the up-regulation of TREM2 and LAMP1 to adjust MG phagocytic activity and intracellular degradation, and promote remyelination.
