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.

OBJECTIVE To compare the efficacy and safety of infliximab（IFX）， ustekinumab（UST） and vedolizumab（VDZ） in the treatment of active Crohn’s disease （CD）. METHODS The patients with active CD who were diagnosed and initially received any of the aforementioned biologics at the First Affiliated Hospital of the USTC （Anhui Provincial Hospital） from January 2020 to December 2023 were selected as the study subjects. They were divided into the IFX group （34 cases）， the UST group （37 cases）， and the VDZ group （15 cases） based on their treatment regimens. Patients in all three groups received induction and maintenance therapy with IFX， UST or VDZ for at least 12 months. The CD Activity Index （CDAI） scores and their changes from baseline （ΔCDAI）， clinical remission rates， clinical response rates， nutritional indicators [body mass index （BMI）， albumin （ALB）， hemoglobin （HGB）]， and inflammatory markers [C-reactive protein （CRP）， erythrocyte sedimentation rate （ESR）] of three groups after the induction phase （9th week of treatment） and during the maintenance phase （12th month of treatment） were compared. Additionally， the cumulative clinical remission rates at 1 year of treatment and the incidence of adverse events （AEs） were compared. RESULTS There were no statistically significant differences in the aforementioned baseline indicators among the three groups （ P ＞0.05）. In all three groups， the CDAI scores were significantly lower after the induction phase and during the maintenance phase， compared to the baseline （ P ＜0.05）. In the IFX group， CDAI scores at the above time points were significantly lower than those in the UST and VDZ groups during the same periods （ P ＜0.05）， and the absolute value of ΔCDAI during the maintenance phase was significantly higher than that in the VDZ group （ P ＜0.05）. The clinical remission rate in the IFX group during the maintenance phase was significantly higher than that in the UST and VDZ groups during the same period， and the clinical response rate was significantly higher than that in the VDZ group during the same period （ P ＜0.05）. The levels of ALB， HGB， CRP and ESR in the IFX group after the induction phase and during the maintenance phase， as well as the levels of CRP and ESR in the UST group after the induction phase， all improved significantly compared to the baseline. Furthermore， the levels of ALB and HGB in the IFX group were significantly higher than those in the UST and VDZ groups during the same period （ P ＜0.05）. The cumulative clinical remission rates among the three groups were significantly different （ P ＜0.05）， with patients in the IFX group achieving remission more rapidly and at a higher proportion. There was no statistically significant difference in the incidence of AEs among IFX， UST and VDZ groups （14.71%， 8.11% and 20.00%， respectively； P ＞0.05）； infusion reactions were the most common AEs in the IFX group （8.82%）. CONCLUSIONS Compared with UST and VDZ， IFX demonstrates a higher clinical remission rate during the maintenance phase， more effectively improves active CD patients’ nutritional status， and continuously reduces systemic inflammatory responses. However， clinicians should be mindful of the risk of adverse events， such as infusion reactions， associated with this drug.

BACKGROUND: Molecular subtyping is an essential complementarity after pathological analyses for targeted therapy. This study aimed to investigate the consistency of next-generation sequencing (NGS) results between circulating tumor DNA (ctDNA)-based and tissue-based in non-small cell lung cancer (NSCLC) and identify the patient characteristics that favor ctDNA testing. METHODS: Patients who diagnosed with NSCLC and received both ctDNA- and cancer tissue-based NGS before surgery or systemic treatment in Lung Cancer Center, Sichuan University West China Hospital between December 2017 and August 2022 were enrolled. A 425-cancer panel with a HiSeq 4000 NGS platform was used for NGS. The unweighted Cohen's kappa coefficient was employed to discriminate the high-concordance group from the low-concordance group with a cutoff value of 0.6. Six machine learning models were used to identify patient characteristics that relate to high concordance between ctDNA-based and tissue-based NGS. RESULTS: A total of 85 patients were enrolled, of which 22.4% (19/85) had stage III disease and 56.5% (48/85) had stage IV disease. Forty-four patients (51.8%) showed consistent gene mutation types between ctDNA-based and tissue-based NGS, while one patient (1.2%) tested negative in both approaches. Patients with advanced diseases and metastases to other organs would be suitable for the ctDNA-based NGS, and the generalized linear model showed that T stage, M stage, and tumor mutation burden were the critical discriminators to predict the consistency of results between ctDNA-based and tissue-based NGS. CONCLUSION ctDNA-based NGS showed comparable detection performance in the targeted gene mutations compared with tissue-based NGS, and it could be considered in advanced or metastatic NSCLC.

Although cisplatin is a widely used chemotherapeutic agent, it is severely toxic and causes irreversible hearing loss, restricting its application in clinical settings. This study aimed to determine the molecular mechanism underlying cisplatin-induced ototoxicity. Here, we established in vitro and in vivo ototoxicity models of cisplatin-induced hair cell loss, and our results showed that reducing STING levels decreased inflammatory factor expression and hair cell death. In addition, we found that cisplatin-induced mitochondrial dysfunction was accompanied by cytosolic DNA, which may act as a critical linker between the cyclic GMP-AMP synthesis-stimulator of interferon genes (cGAS-STING) pathway and the pathogenesis of cisplatin-induced hearing loss. H-151, a specific inhibitor of STING, reduced hair cell damage and ameliorated the hearing loss caused by cisplatin in vivo. This study underscores the role of cGAS-STING in cisplatin ototoxicity and presents H-151 as a promising therapeutic for hearing loss.

Infectious keratitis (IK) is a leading cause of blindness worldwide, primarily resulting from improper contact lens use, trauma, and a compromised immune response. The pathogenic microorganisms responsible for IK include bacteria, fungi, viruses, and Acanthamoeba. This review examines standard therapeutic agents for treating IK, including broad-spectrum empiric antibiotics for bacterial keratitis (BK), antifungals such as voriconazole and natamycin for fungal infections, and antiviral nucleoside analogues for viral keratitis (VK). Additionally, this review discusses therapeutic agents, such as polyhexamethylene biguanide (PHMB), for the treatment of Acanthamoeba keratitis (AK). The review also addresses emerging drugs and the challenges associated with their clinical application, including anti-biofilm agents that combat drug resistance and nuclear factor kappa-B (NF-κB) pathway-targeted therapies to mitigate inflammation. Furthermore, methods of Photodynamic Antimicrobial Therapy (PDAT) are explored. This review underscores the importance of integrating novel and traditional therapies to tackle drug resistance and enhance drug delivery, with the goal of advancing treatment strategies for IK.

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 analyze the clinical features and genetic sequencing results of a patient with Kallmann syndrome(KS) carrying digenic mutations who initially presented with osteoporosis, and to enhance awareness of this disease phenotype.Methods:Clinical data were collected, and peripheral blood DNA was extracted for whole-exome sequencing. Relevant literature was reviewed to summarize phenotypes associated with digenic/oligogenic variants involving CHD7.Results:The patient exhibited back pain, delayed development of secondary sexual characteristics, and hyposmia. Laboratory tests revealed reduced sex hormones and gonadotropin levels, while pituitary imaging was unremarkable. Bone mineral density imaging confirmed osteoporosis, and thoracolumbar X-rays showed multiple vertebral compression fractures. Genetic analysis identified a heterozygous splice-site mutation in CHD7(c.2698-1G>T) and a heterozygous missense mutation in WDR11(c.439G>A: p.D147N). According to ACMG criteria, the CHD7 mutation was classified as pathogenic, while the WDR11 variant was defined as a variant of uncertain significance(VUS). Literature review indicated that 40% of KS patients with digenic/oligogenic variants involving CHD7 presented with hearing or ocular abnormalities.Conclusion:This study reports a novel CHD7 mutation and a previously undescribed digenic combination of CHD7 and WDR11 variants in a KS patient. CHD7 variants may be implicated in auditory or ocular involvement in KS cases with digenic/oligogenic inheritances. KS patients may also manifest skeletal abnormalities in addition to hypogonadotropic hypogonadism. Tailored management of sex hormones and osteoporosis therapies across life stages is essential for optimizing bone health in KS.

Objective:To analyze the epidemiological characteristics of severe fever with thrombocytopenia syndrome (SFTS) in Beijing in 2024, to investigate the infection status of reservoir hosts, vector organisms, and baseline human populations, and provide a scientific basis for formulating prevention and control strategies.Methods:Epidemiological surveys were conducted on all confirmed cases. Serum samples from healthy populations and reservoir hosts were collected for SFTSV antibody detection. Questing ticks were monitored using the flagging method. Real-time fluorescent quantitative PCR was employed to detect SFTSV in cases, reservoir hosts, and ticks. Positive samples underwent whole-genome sequencing and genetic evolution analysis.Results:In 2024, Beijing reported 15 locally infected cases with 4 deaths. The age of onset ranged from 50 to 80 years (median: 66 years). Cases showed a certain degree of geographical clustering, with June being the peak month of onset. The affected population was predominantly farmers, with a male-to-female ratio of 3∶2. Animal contact history emerged as a significant risk factor alongside tick bites. Parthenogenetic tick populations were identified in Pinggu district, while SFTSV-carrying ticks were detected in endemic areas (Mentougou, Shijingshan, and Fengtai Districts). Viral presence was also confirmed in ticks or dogs from non-endemic areas. Sequencing and phylogenetic analysis revealed stable clustering of strains into two distinct genotypes (A and B). Antibody-positive individuals were identified in healthy populations from non-endemic areas.Conclusions:The incidence of SFTS in Beijing is increasing, with natural viral circulation already established in non-endemic regions. Enhanced surveillance and adjusted prevention strategies are urgently needed.

Objective:Primary sclerosing cholangitis (PSC) is a rare autoimmune disease. This study aims to describe the baseline characteristics and clinical outcomes of Chinese PSC patients and explore risk factors associated with prognosis, addressing the lack of long-term prognostic analysis in China.Methods:Clinical data of PSC patients were retrospectively collected from May 2009 to June 2023 in Beijing Friendship Hospital Affiliated to Capital Medical University, and patient follow-up was conducted through outpatient visits, telephone calls, and medical record reviews. The Cox proportional hazards model and the Kaplan-Meier method were employed to identify risk factors and estimate transplant-free survival.Results:A total of 65 PSC patients were enrolled, with male patients accounting for 50.8% and an average age of onset of 44 years. The disease types primarily included large duct PSC (57.9%) and whole duct PSC (22.8%). Most patients (78.5%) sought medical attention due to symptoms, with common clinical manifestations including jaundice (32.3%), fatigue (23.1%), abdominal discomfort (21.5%), pruritus (16.9%), and fever (10.8%). A total of 19 patients (29.2%) had concomitant ulcerative colitis. Compared to large duct PSC or whole duct PSC, small duct PSC showed a lower proportion of concomitant ulcerative colitis ( P<0.001) and milder baseline disease severity. After a median follow-up of 29 months (interquartile range: 11,53), 19 patients experienced liver transplantations and/or liver disease-related deaths. The overall 2-year and 5-year transplant-free survival rates for PSC patients were 76.0% and 59.5%, respectively. Elevated bile acid levels were identified as an independent risk factor for poor outcomes in PSC patients. Conclusion:The study population of Chinese PSC patients predominantly consisted of middle-aged males, characterized by a low ratio of asymptomatic cases, a low incidence of associated inflammatory bowel disease, and a low rate of transplant-free survival. Elevated bile acid level was identified as an independent risk factor for poor outcomes in PSC patients.
