Objective:To investigate the sleep status of preschool children in Zhongshan City and the OSA-18 questionnaire scores among healthy preschool children. Methods:A cluster sampling method was adopted to select 2 222 students from 5 non-boarding kindergartens in Zhongshan from October 2022 to October 2023 as study subjects. Data were collected via an online questionnaire platform and analyzed using SPSS 27.0 statistical software. Results:A total of 1 317 valid questionnaires were collected, with an average sleep duration of（8.74±0.75） hours among children. The results of stepwise regression analysis showed that child age, prematurity, sleep latency, daily outdoor activity time, and activities within 30 minutes before bedtime were factors influencing children's nocturnal sleep duration（P<0.05）. The overall incidence of sleep disorder-related symptoms was 56.80%, including restless sleep（24.14%）, difficulty falling asleep（24.07%）, snoring with mouth breathing（14.20%）, bruxism（11.16%）, enuresis（10.55%）, sleep talking（6.08%）, limb twitching（2.74%）, and sleepwalking（0.53%）. Various factors influenced these symptoms, and binary logistic regression analysis identified allergic diseases and a smaller number of siblings at home as the most prevalent risk factors（P<0.05）. The overall OSA-18 score was 34.11±12.14, and binary logistic regression analysis identified males, allergic diseases, and tonsillar hypertrophy as risk factors for high OSA-18 scores（≥60）（P<0.05）. Conclusion:In Zhongshan City, the nocturnal sleep duration of preschool children decreases with age, with independent risk factors for this prematurity, longer sleep latency, shorter daily outdoor activity time, and the use of electronic devices within 30minute before bedtime. Allergic diseases and a smaller number of siblings at home increase the risk of sleep-disordered breathing symptoms. Males, allergic diseases, and tonsillar hypertrophy have higher OSA-18 scores.

OBJECTIVE: This study aimed to evaluate the association between susceptibility genes and non-alcoholic fatty liver disease (NAFLD) in children with obesity. METHODS: We conducted a two-step case-control study. Ninety-three participants were subjected to whole-exome sequencing (exploratory set). Differential genes identified in the small sample were validated in 1,022 participants using multiplex polymerase chain reaction and high-throughput sequencing (validation set). RESULTS: In the exploratory set, 14 genes from the NAFLD-associated pathways were identified. In the validation set, after adjusting for sex, age, and body mass index, ECI2 rs2326408 (dominant model: OR = 1.33, 95% CI: 1.02-1.72; additive model: OR = 1.22, 95% CI: 1.01-1.47), C6orf201 rs659305 (dominant model: OR = 1.30, 95% CI: 1.01-1.69; additive model: OR = 1.21, 95% CI: 1.00-1.45), CALML5 rs10904516 (pre-ad dominant model: OR = 1.36, 95% CI: 1.01-1.83; adjusted dominant model: OR = 1.40, 95% CI: 1.03-1.91; and pre-ad additive model: OR = 1.26, 95% CI: 1.04-1.66) polymorphisms were significantly associated with NAFLD in children with obesity ( P < 0.05). Interaction analysis revealed that the gene-gene interaction model of CALML5 rs10904516, COX11 rs17209882, and SCD5 rs3733228 was optional ( P < 0.05), demonstrating a negative interaction between the three genes. CONCLUSION In the Chinese population, the CALML5 rs10904516, C6orf201 rs659305, and ECI2 rs2326408 variants could be genetic markers for NAFLD susceptibility.

Objective:Non-alcoholic fatty liver disease(NAFLD)has significant genetic susceptibility.Adipocytokines play a crucial role in NAFLD development by participating in insulin resistance and hepatic steatosis.However,the association between adipocytokine pathway genes and NAFLD remains unclear.This study aims to explore the association of gene polymorphisms in the adipocytokine pathway and their interactions with NAFLD in obese children. Methods:A case-control study was conducted,dividing obese children into NAFLD and control groups.Peripheral venous blood(2 mL)was collected from each participant for DNA extraction.A total of 14 single nucleotide polymorphisms(SNP)in the adipocytokine pathway were genotyped using multiplex PCR and high-throughput sequencing.Univariate and multivariate Logistic regression analyses were used to assess the association between SNP and NAFLD in obese children.Dominant models were used to analyze additive and multiplicative interactions via crossover analysis and Logistic regression.Generalized multifactor dimensionality reduction(GMDR)was used to detect gene-gene interactions among the 14 SNPs and their association with NAFLD in obese children. Results:A total of 1 022 children were included,with 511 in the NAFLD group and 511 in the control group.After adjusting for age,gender,and BMI,multivariate Logistic regression showed that PPARG rs1801282 was associated with NAFLD in the obese children in 3 genetic models:heterozygote model(CG vs CC,OR=0.58,95%CI 0.36 to 0.95,P=0.029),dominant model(GG+CG vs CC,OR=0.62,95%CI 0.38 to 1.00,P=0.049),and overdominant model(CC+GG vs CG,OR=1.72,95%CI 1.06 to 2.80,P=0.028).PRKAG2 rs12703159 was associated with NAFLD in 4 genetic models:heterozygous model(CT vs CC,OR=1.51,95%CI 1.10 to 2.07,P=0.011),dominant model(CT+TT vs CC,OR=1.50,95%CI 1.10 to 2.03,P=0.010),overdominant model(CC+TT vs CT,OR=0.67,95%CI 0.49 to 0.92,P=0.012),and additive model(CC vs CT vs TT,OR=1.40,95%CI 1.07 to 1.83,P=0.015).No significant multiplicative or additive interaction between PPARG rs1801282 and PRKAG2 rs12703159 was found in association with NAFLD.GMDR analysis,adjusted for age,gender,and BMI,revealed no statistically significant interactions among the 14 SNPs(all P>0.05). Conclusion:Mutations in PPARG rs1801282 and PRKAG2 rs12703159 are associated with NAFLD in obese children.However,no gene-gene interactions among the SNP are found to be associated with NAFLD in obese children.

The study employed network Meta-analysis to evaluate the efficacy and safety of Chinese patent medicines combined with recombinant human interferon α-2b(interferon) in the treatment of cervical human papillomavirus(HPV) infections. The relevant randomized controlled trial(RCT) published from inception to May 8, 2024 were retrieved from CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science. The modified Jadad scale and the Cochrane risk of bias tool were used to evaluate the quality of the included studies, and RevMan 5.4, R 4.3.3, and Stata 17 were used for data analysis. A total of 105 RCTs were included, involving 12 732 participants and 7 Chinese patent medicines: Baofukang Suppository, Compound Seabuckthorn Seed Oil Suppository, Huangqi Shengmai Decoction, Kangfu Gel, Kangfuyan Capsules, Kushen Gel, and Puling Penyankang Granules. Network Meta-analysis yielded the following results:(1)For improving the negative conversion rate of HPV, SUCRA top-ranked intervention was Puling Penyankang Granules + interferon.(2) For shortening vaginal discharge time, SUCRA top-ranked intervention was Compound Seabuckthorn Seed Oil Suppository + interferon.(3) For reducing the serum level of hypersensitive C-reactive protein(hs-CRP), SUCRA top-ranked intervention was Baofukang Suppository + interferon.(4) For elevating the serum level of CD~+_4 T cells, SUCRA top-ranked intervention was Baofukang Suppository + interferon.(5) For elevating the serum level of CD~+_8 T cells, SUCRA top-ranked intervention was Kangfuyan Capsules + interferon.(6) For improving the CD~+_4/CD~+_8 ratio, SUCRA top-ranked intervention was Compound Seabuckthorn Seed Oil Suppository + interferon.(7)In terms of reducing serum tumor necrosis factor-α(TNF-α), interleukin-6(IL-6), recurrence rate at 6 months after treatment, and incidence of adverse events, there were no significant differences between the interventions when compared pairwise. The cluster analysis revealed that Puling Penyankang Granules + interferon, Baofukang Suppository + interferon, Kangfu Gel + interferon, and Huangqi Shengmai Decoction + interferon simultaneously improved the negative conversion rate of HPV and reduced the incidence of adverse events. The findings suggested that Chinese patent medicines combined with interferon were effective in treating cervical HPV infection by enhancing the negative conversion rate, shortening the vaginal discharge time, and improving the levels of hs-CRP and T lymphocyte subsets. However, due to the limitations of sample size and quality of the included studies, these conclusions require further validation by studies with larger sample sizes and higher quality.

Objective:To analyze the experiences and practice in the reform of public hospital salary system in Sichuan province, summarize the typical modes of such reform in the province, and provide references for further reform.Methods:As of October 29, 2021, the research group received 77 sets of typical experience materials submitted by the health commissions and public hospitals in Sichuan province on enforcing the reform of the public hospital salary system. The analysis framework was based on the five main elements proposed in the Guidance to Deepening the Reform of the Salary System of Public Hospitals for the purpose of furthering the reform. These five elements refer to " reasonably determining the level of salary in public hospitals" " fully implementing the autonomy of internal distribution in public hospitals " " establishing and improving the incentive and restraint mechanism for the remuneration of public hospital leaders" " improving the assessment and evaluation mechanism oriented to public welfare" and " funding sources ". A quantitative analysis was made on the typical experience materials using the social network analysis method, while a qualitative analysis was made on the typical experience materials using the content analysis method. Results:The results of social network analysis showed that the network density was 0.272; the highest point centrality was " fully implement the autonomy of internal distribution in public hospitals" (0.935), and the highest intermediary centrality was " improving the assessment and evaluation mechanism oriented to public welfare" (0.870), while the closeness to centrality of " establishing and improving the incentive and constraint mechanism for the salary of public hospital leaders" (0.434) and " funding sources" (0.421) were relatively low. The results of content analysis showed that the ones with higher frequency among all the typical experience materials were " fully implementing the autonomy of internal distribution of hospitals" (72 times) and " improving the assessment and evaluation mechanism oriented to public welfare" (67 times), while the ones with lower frequency were " establishing and improving the salary incentive and constraint mechanism for public hospital leaders" (17 times) and " funding sources" (14 times). In terms of unity and synergy, the typical models of public hospital salary system reform in the province could be categorized as the fine standard mode, the fair value mode, the autonomous synergy mode and the circular symbiosis mode.Conclusions:Deepening the reform of the salary system of public hospitals should unify the standards and improve the fair and refined assessment and evaluation mechanism; explore various forms of distribution and build an internal autonomous and synergistic incentive mechanism; pay attention to the weak remuneration incentive mechanism for hospital leaders and the problem of a relatively single source of funding.

Objective:To compare the effects of citrate and heparin anticoagulation on coagulation function and efficacy in children with septic shock undergoing continuous blood purification (CBP), and to provide guidance for CBP anticoagulation in children with septic shock.Methods:A case control study was conducted. Thirty-seven children with septic shock admitted to the pediatric intensive care unit (PICU) of the First Affiliated Hospital of Gannan Medical University from July 2019 to September 2022 were enrolled as the research subjects. The patients were divided into citrate local anticoagulation group and heparin systemic anticoagulation group according to different anticoagulation methods. The baseline data, the level of coagulation indicators [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib), D-dimer] before treatment and 1 day after weaning from CBP, serum inflammatory mediators [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), hypersensitivity C-reactive protein (hs-CRP), procalcitonin (PCT)], bleeding complications during CBP and 7-day mortality were collected.Results:A total of 37 cases were enrolled finally, including 17 cases with citric acid local anticoagulation and 20 cases with heparin systemic anticoagulation. There was no statistically significant difference in general data such as gender, age, and body weight of children between the two groups. There were no statistically significant differences in baseline levels of coagulation indicators and inflammatory mediators before treatment of children between the two groups. One day after weaning from CBP, both groups showed varying degrees of improvement in coagulation indicators compared with those before treatment. Compared with before treatment, the PT of the heparin systemic anticoagulation group was significantly shortened after 1 day of weaning (s: 11.82±2.05 vs. 13.64±2.54), APTT and TT were significantly prolonged [APTT (s): 51.54±12.69 vs. 35.53±10.79, TT (s): 21.95±4.74 vs. 19.30±3.33], D-dimer level was significantly reduced (mg/L: 1.92±1.58 vs. 4.94±3.94), with statistically significant differences (all P < 0.05). While in the citrate local anticoagulation group, only APTT was significantly prolonged after treatment compared with that before treatment (s: 49.28±10.32 vs. 34.34±10.32, P < 0.05). There were no statistically significant differences in other coagulation indicators compared with before treatment. Compared with the citric acid local anticoagulation group, the PT of the heparin systemic anticoagulation group was significantly shortened after treatment (s: 11.82±2.05 vs. 13.61±3.05, P < 0.05), and the D-dimer level was significantly reduced (mg/L: 1.92±1.58 vs. 3.77±2.38, P < 0.01). The levels of inflammatory mediators in both groups were significantly reduced 1 day after CBP weaning compared with those before treatment [citric acid local anticoagulation group: hs-CRP (mg/L) was 12.53±5.44 vs. 22.65±7.27, PCT (μg/L) was 1.86±1.20 vs. 3.30±2.34, IL-6 (ng/L) was 148.48±34.83 vs. 202.32±48.62, TNF-α (ng/L) was 21.38±7.71 vs. 55.14±15.07; heparin systemic anticoagulation group: hs-CRP (mg/L) was 11.82±4.93 vs. 21.62±8.35, PCT (μg/L) was 1.90±1.08 vs. 3.18±1.97, IL-6 (ng/L) was 143.81±33.41 vs. 194.02±46.89, TNF-α (ng/L) was 22.44±8.17 vs. 56.17±16.92, all P < 0.05]. However, there was no statistically significant difference between the two groups (all P > 0.05). There was no statistically significant difference in bleeding complication during CBP and 7-day mortality in children between the citrate local anticoagulation group and the heparin systemic anticoagulation group (5.9% vs. 30.0%, 17.6% vs. 20.0%, both P > 0.05). Conclusions:Heparin for systemic anticoagulation and regional citrate anticoagulation can significantly reduce the levels of IL-6, TNF-α, hs-CRP and PCT in children with septic shock, and relieve inflammatory storm. Compared with citric acid local anticoagulation, heparin systemic anticoagulation can shorten the PT and reduce the level of D-dimer in children with septic shock, which may benefit in the prevention and treatment of disseminated intravascular coagulation (DIC).

The acute combination fractures of the atlas and axis in adults have a higher rate of neurological injury and early death compared with atlas or axial fractures alone. Currently, the diagnosis and treatment choices of acute combination fractures of the atlas and axis in adults are controversial because of the lack of standards for implementation. Non-operative treatments have a high incidence of bone nonunion and complications, while surgeries may easily lead to the injury of the vertebral artery, spinal cord and nerve root. At present, there are no evidence-based Chinese guidelines for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults. To provide orthopedic surgeons with the most up-to-date and effective information in treating acute combination fractures of the atlas and axis in adults, the Spinal Trauma Group of Orthopedic Branch of Chinese Medical Doctor Association organized experts in the field of spinal trauma to develop the Evidence-based guideline for clinical diagnosis and treatment of acute combination fractures of the atlas and axis in adults ( version 2023) by referring to the "Management of acute combination fractures of the atlas and axis in adults" published by American Association of Neurological Surgeons (AANS)/Congress of Neurological Surgeons (CNS) in 2013 and the relevant Chinese and English literatures. Ten recommendations were made concerning the radiological diagnosis, stability judgment, treatment rules, treatment options and complications based on medical evidence, aiming to provide a reference for the diagnosis and treatment of acute combination fractures of the atlas and axis in adults.
