BackgroundObstructive sleep apnea （OSA） represents a prevalent sleep disordered breathing condition characterized by complex pathophysiology. The arousal threshold （ArTH）， a core non-anatomical contributor to OSA pathogenesis， is intimately tied to the disease severity and clinical phenotypes. To date， research regarding factors associated with ArTH has yielded inconsistent findings， and ArTH profiles and disparities across populations with different genetic backgrounds are not fully elucidated. ObjectiveTo explore the differences of ArTH in OSA patients with different genetic backgrounds and analyze the key factors affecting ArTH， thereby providing evidence for understanding OSA pathophysiology and formulating targeted treatment regimens. MethodsA total of 285 patients who met the diagnostic criteria for OSA， as defined by the Multidisciplinary Diagnosis and Treatment Guidelines for Adult Obstructive Sleep Apnea， were retrospectively enrolled in this study. All participants underwent overnight polysomnography （PSG） at the Sleep Medicine Center of Inner Mongolia Mental Health Center from December 2022 to May 2024. Based on the study design， the cohort was stratified into two distinct genetic background subgroups （group A and group B）. Demographic and clinical characteristics， the Epworth Sleepiness Scale （ESS） score， and overnight PSG data were collected. The apnea hypopnea index （AHI）， the lowest pulse oxygen saturation （LSpO₂）， and fraction of hypopneas （F_Hypopneas） were utilized as surrogate indicators to estimate ArTH in OSA patients. The influencing factors of low ArTH were tested by binary Logistic regression analysis. ResultsAmong the 285 OSA patients， there were 227 cases （79.65%） in group A and 58 cases （20.35%） in group B. Comparisons between the two genetic background subgroups revealed no statistically significant differences in the proportion of low ArTH， ESS score， PSG parameters， and the three markers for low ArTH （AHI<30 events/h， LSpO₂>82.5%， F_Hypopneas>58.3%） （P>0.05）. Binary Logistic regression analysis identified sex （OR=2.421， 95% CI： 1.070–5.478）， BMI （OR=0.847， 95% CI： 0.770–0.932）， N1 sleep duration （OR=0.974， 95% CI： 0.963–0.985）， and hypertension （OR=0.348， 95% CI： 0.143–0.848） as independent factors associated with low ArTH in the total cohort. Stratified analysis by genetic backgrounds revealed that sex（OR=3.799， 95% CI： 1.389–10.392）， BMI（OR=0.819， 95% CI：0.723–0.929）， and N1 sleep duration（OR=0.973， 95% CI： 0.961–0.986） were independent factors of low ArTH in group A. In contrast， only N1 sleep duration （OR=0.951， 95% CI： 0.911–0.993） remained a significant factor in group B. ConclusionArthur may have conservative characteristics in patients with OSA with different genetic backgrounds， but the pathophysiological mechanism of OSA may have population heterogeneity. ［Funded by Inner Mongolia Autonomous Region Natural Science Fundation Project （number， 2024QN08050）； Intra-institutional Scientific Research Project of Inner Mongolia Mental Health Center （number， 2022QNWN0010）］

ObjectiveThis study aimed to explore the correlation between the quality of life （QOL） and different traditional Chinese medicine （TCM） syndromes in patients with myasthenia gravis （MG）， identifying potential influencing factors to provide new insights for clinical interventions and improving the QOL of patients with MG. MethodsA questionnaire survey was conducted on 93 adults with MG who visited the Department of Neurology at the Affiliated Hospital of Changchun University of Chinese Medicine from March 2023 to January 2024. Statistical analysis was performed on the clinical data collected using SPSS 24.0 software. ResultsAmong the 93 patients with MG， the average score for myasthenia gravis quality of life-15 （MGQOL-15） was 17.65±6.27， and that for the 36-item short form health survey （SF-36） was （106.13±11.83） scores. The QOL was rated as good for 16 patients and moderate for 77 patients. There were no statistically significant differences in the scores of MGQOL-15， SF-36， and their individual scales by gender or education level. Age showed statistically significant differences in MGQOL-15 and the role physical （RP） scale （P<0.05）， and occupational type showed significant differences in the vitality （VT） scale （P<0.01）. The Myasthenia Gravis Foundation of America （MGFA） classification had statistical significance on the total SF-36 score （P<0.01）， VT scale （P<0.01）， role emotional （RE） scale （P<0.05）， social functioning （SF） scale （P<0.05）， and physical functioning （PF） scale （P<0.01）. Among patients with different TCM syndromes， there were significant differences in MGQOL-15 scores （F=4.919， P<0.01）. Moreover， significant differences were observed in SF-36 scores （P<0.01）， VT scale （P<0.01）， RE scale （P<0.05）， mental health （MH） scale （P<0.01）， and SF scale （P<0.05）. ConclusionFactors affecting the QOL of patients with MG include age， occupational type， and clinical classification of MG. Specifically， a greater impact on the QOL of older patients is observed， while physical laborers have a poorer QOL compared to non-physical laborers. Patients classified as MGFA type Ⅱ and higher have a poorer QOL. Additionally， there is a potential correlation between the QOL and TCM syndromes， with patients presenting with spleen and kidney Qi deficiency having a lower QOL than those with spleen and stomach Qi deficiency or Qi and Yin deficiency， which is particularly evident in the VT， RE， MH， and SF scales.

Objective:To construct a questionnaire to measure parents′ behavioral and social drivers (BeSD) in administering rotavirus vaccine to their children, and to test the reliability and validity of the questionnaire.Methods:A questionnaire was constructed to investigate the BeSD of rotavirus vaccination among parents based on the WHO BeSD questionnaire. A survey was conducted among parents of children aged 0-3 years old in vaccination clinics from 15 community health service centers in Nanjing City of Jiangsu Province, Yuhuan and Kaihua Counties of Zhejiang Province, Anqing City of Anhui Province, and Yangpu District of Shanghai City from April to May in 2024. Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to analyze the reliability (internal consistency reliability, combination reliability and split half reliability) and validity (structural validity, convergence validity and discriminative validity) of the questionnaire.Results:A total of 850 questionnaires were collected, of which 614 were valid, with an effective response rate of 72.20%. The EFA resulted in the refinement of the rotavirus vaccine BeSD questionnaire from 37 to 35 items (including 24 core items), and suggested a five-factor structure including the perceptions of vaccine, confidence in vaccine, social process of vaccination, motivation for vaccination, and practical problems of vaccination. The cumulative variance contribution rate reached 56.27%. The CFA confirmed an ideal five-factor model fit (GFI=0.82,CFI=0.86,PNFI=0.67,RMSEA=0.07). The AVE of each dimension was greater than 0.50. The AVE square root of each dimension of the questionnaire was greater than its correlation coefficient. The Cronbach′s α coefficient of the total questionnaire was 0.79.Conclusion:The developed BeSD questionnaire of rotavirus vaccine has good reliability and validity, and can be used to measure parents′ behavioral and social factors in administering rotavirus vaccine to their children.

Stroke is one of the most common cerebrovascular diseases， including hemorrhagic stroke and ischemic stroke. From a modern medical perspective， stroke is caused by cerebrovascular damage or embolism leading to impaired blood circulation. From the traditional Chinese medicine （TCM） perspective， the pathogenesis of this disease is mainly due to the disorder of Qi and blood， which ascend to the brain， causing either blood extravasation or blockage of brain collaterals. Stasis is a pathological factor that runs throughout the entire course of stroke， and the method of promoting blood circulation and resolving stasis has been a core treatment for stroke for a long time. Hirudo， as a traditional insect drug， has shown good effects in promoting blood circulation and resolving stasis. Modern pharmacological research has confirmed that Hirudo contains anticoagulant components， which provide significant advantages in dissolving thrombi in ischemic stroke and facilitating hematoma absorption in hemorrhagic stroke. Hirudo and its related preparations have been proven to exert an anti-stroke effect through anticoagulation， anti-thrombosis， and protection of vascular endothelium. As a result， they have been widely used in the treatment of stroke. This article explored the theoretical basis and research status of using Hirudo for treating stroke based on its main active components and hemostatic properties and summarized the current research status of commonly used Hirudo-based formulations and preparations， aiming to provide references for the involvement of Hirudo in stroke treatment.

Objective To evaluate the endoscopic features of colorectal sessile serrated adenoma/polyp(SSA/P). Methods The data of 109 cases of SSA/P and 218 cases of polyps randomly selected in Xijing Hospital from January 2014 to December 2016 were collected. The endoscopic features of SSA/P and polyps were compared, and the risk factors of occurrence and cancerization of SSA/P were analyzed. Results The mean age of patients in the SSA/P group was older than that of polyps group(P=0.011).The distribution of lesions was no significant difference between the two groups(P=0.092). The gross type of SSA/P was mainly type Ⅰ and Ⅱ, while polyps were more in type Ⅰ(P=0.036). According to the pit pattern of Kudo,type Ⅱ was more in SSA/P,but types Ⅰ and Ⅱ were more in polyps(P=0.004). For capillary pattern comparison,type Ⅱ was more in SSA/P,but type Ⅰ was more in polyps(P≤0.000 1). For surface morphological features comparison,the SSA/P group was more likely to be observed the mucous cap(P=0.002)and blood vessel thickening(P=0. 004). On pathologic diagnosis, the SSA/P group was more susceptible to atypia and carcinogenesis(P = 0.001). Higher microvascular morphological classification,being mucous cap,and blood vessel thickening were risk factors of atypia and carcinogenesis of SSA/P. Conclusion There were significant differences between SSA/P and polyps on lesion location,pit pattern,capillary pattern,surface structure characteristics,and risk factors of atypia and carcinogenesis.

Objective To compare the safety and efficacy of endoscopic submucosal tunnel dissection (ESTD) and endoscopic submucosal dissection ( ESD) for treatment of esophageal superficial neoplasms. Methods A retrospective study was performed on data of patients with esophageal superficial neoplasms who were treated by conventional ESD or ESTD at Xijing Hospital of Digestive Diseases between January 2014 and December 2016. The procedure time, pathology, rate of en bloc resection and curative resection, and adverse events were compared between the two groups. Results A total of 113 consecutive patients were collected, including 49 undergoing ESTD and 64 undergoing ESD. ESTD had a shorter procedure time than ESD method [38. 0 min(21. 4-71. 0 min) VS 46. 5 min(32. 5-117. 5 min), P＝0. 008],and the dissection speed of ESTD was faster than that of ESD[0. 42 cm2/min(0. 22-0. 59 cm2/min) VS 0. 34 cm2/min(0. 20-0. 42 cm2/min), P＝0. 000]. There were no statistical differences in the en bloc resection rate ( 100. 0% VS 100. 0%, P＝1. 000) or the curative resection rate (98. 0% VS 93. 8%, P＝0. 386).There were no statistical differences on adverse event rates including post-procedure bleeding, perforation, fever, and thoracalgia.ESTD group showed a lower rate of muscular injury (20. 4% VS 39. 1%, P＝0. 041) and intra-procedure bleeding (18. 4% VS 37. 5%, P＝0. 036). A multivariate regression analysis for procedure time showed that ESTD method ( OR＝ 2. 801, 95%CI: 1. 116-7. 031, P＝0. 028) and lesion area ＜9 cm2(OR＝5. 049, 95%CI: 2. 088-12. 208, P＝0. 000) were associated with a shorter procedure time.Conclusion ESTD is safe and effective for treatment of esophageal superficial neoplasms. It can shorten operative time, improve dissection speed, and reduce intra-procedure muscular layer injury and bleeding.

Objective To explore the diagnosis and treatment of empyema in children. Method The clinical data of empyema in 49 children were reviewed and analyzed. Results In the 49 cases (25 males and 24 females) aged 4.7±3.4 years, the common symptoms were fever, shortness of breath and coughing. There were 11 cases of positive blood culture, 17 cases of positive pleural fluid culture, 3 cases of positive blood and pleural fluid culture. Streptococcus pneumoniae was the most common pathogenic bacteria. All 49 patients were given systemic antibiotics and closed thoracic drainage. In addition, 26 cases were treated with urokinase and intrapleural fibrinolytic therapy and 6 cases were treated surgically. The prognosis was good and there was no death. Conclusion Pneumococcal infection is most common in children with empyema. Systemic antibiotics plus closed thoracic drainage and urokinase are effective, and some require surgical treatment.
