OBJECTIVE: To measure the upper airway of obstructive sleep apnea-hypopnea syndrome by speed CT. We can predict the airway obstruction plane with the airway plane data and compliance in OSAHS patients. Through this measurement, we can provide assistance for clinical diagnosis and treatment. METHOD: This study randomly selected 82 patients diagnosed with OSAHS and 45 cases non-snoring healthy people as control group by the PHILIPS 256-slice CT. The zone volume, sagittal diameter, coronary diameter and cross-sectional area of the narrowest plane in nasopharyngeal area, velopharyngeal area, glossopharyngeal area, hypopharynx area in two groups of quiet respiration and Müller's status were measured. RESULT: In the OSAHS group underwent quiet breathing and Müller movement during CT scanning, the two states about nasopharyngeal coronary diameter, the hypopharynx sagittal diameter and cross-sectional area showed no significant difference, while other groups showed differences between the parameters (P<0.05). There was significant difference (P<0.01) in the velopharyngeal volume, tongue sagittal diameter and volume. Under Müller movement in the OSAHS group and the control group, the hypopharynx volume showed no significant difference. The nasopharyngeal coronary diameter and volume, velopharyngeal cross-sectional area and tongue sagittal diameter were different (P<0.05). The remaining set of parameters showed significant differences (P<0.01). Compared the airway compliance (Müller phase) of the OSAHS group and the control group,the parameters of each group were different (P<0.05), of which the nasopharyngeal sagittal diameter, velopharyngeal volume showed significant difference (P<0.01). Meanwhile, in the same plane, coronary diameter was greater than sagittal diameter (P<0.05) in both the OSAHS group and the control group. The pharyngeal volume measurement was basically consistent to the fiber endoscopy. CONCLUSION The obstruction plate of OSAHS patients is mostly in the velopharyngeal area and glossopharyngeal area measured with a high speed CT. The volume measurement of upper airway with speed CT can predict airway obstruction plate in patients with OSAHS.

Objective:To evaluate the quality of information about bronchial asthma in Chinese Internet Site.Methods:According to the traffic ranking of Alexa website, three Chinese keywords of “bronchial asthma”, “asthma” and “asthma treatment” were searched in two most common Chinese search engines: Baidu and Sohu, and the information quality was evaluated by DISCERN tool. The completeness and accuracy of the information were evaluated according to the “2019 Global Strategy For Asthma Management And Prevention”.Results:A total of 25 websites were obtained. The DISCERN evaluation showed that none of the evaluations had an average score of more than 3.40 points. More than 50% of the information on the websites was incomplete or incorrect, and 4% of the websites contained incorrect information. The website content scores were graded, and the grading results were: excellent 12%, good 40%, fair 36%, poor 12%. The website was evaluated according to the attributes of the owner. Professional websites had better accuracy and comprehensive websites had better comprehensiveness. Pearson correlation analysis showed that the content score was positively correlated with the reliability score, detail score, and total score in DISCERN score ( r=0.58, 0.63, 0.61, all P<0.001). Conclusion:The quality of asthma information on Chinese Internet Site is generally poor.

To explore the prevalence and related risk factors of osteoporosis (OP) in the elderly ≥60 years old in Jiuting Town, Songjiang District, Shanghai City. A total of 2 175 local residents aged ≥60 years old who participated in the questionnaire survey at the physical examination center of Jiuting Community Health Service Center, Songjiang District, Shanghai City from July 2021 to December 2022 were selected by a cross-sectional study with multi-stage sampling method. Questionnaire survey, blood test and bone mineral density (BMD) test were conducted.The differences in all the parameters among the elderly with different bone mass level were analyzed using t-test, chi-square test, binary logistic regression was used to screen the potential risk factors of OP.The results showed that the prevalence of OP in the elderly aged≥60 years old in Jiuting Town was 45.89%.The prevalence of OP increased gradually with the advanced age. The prevalence rate of male was significantly lower than that of female( χ2=211.94, P<0.01).Single factor analysis showed that Dairy products( χ2=9.01, P<0.05), taking calcium( χ2=42.88, P<0.05), physical exercise( χ2=24.73, P<0.05), exercise time( χ2=76.40, P<0.05) and sun exposure( χ2=55.71, P<0.05) were the protective factors for osteoporosis. Multifactor analysis showed that female( wald χ 2=71.46, P<0.001) were the risk factors for osteoporosis. The age of the osteoporosis group was older than that of the non-osteoporosis group [osteoporosis group (72.47±6.89) years old, non-osteoporosis group (68.73±6.34) years old, and the difference was statistically significant, t=-11.67, P<0.05]. The waist circumference, alanine aminotransferase (ALT), creatinine (CR), blood urea nitrogen (BUN) and uric acid (UA) in the non-osteoporosis group were higher than those in the osteoporosis group, and the difference was statistically significant (all P<0.05). The levels of high-density lipoprotein (HDL)[osteoporosis group (1.34±0.35) mol/L, non-osteoporosis group (1.41±0.35) mol/L, t=-4.51, P<0.05] and alkaline phosphatase (ALP)[osteoporosis group (88.46±25.65) mol/L, osteoporosis group (94.56±32.32) mol/L, t=-4.79, P<0.05] in the osteoporosis group were lower than those in the non-osteoporosis group.Low awareness of the knowledge of osteoporosis risk factors(smoking, drinking coffee, high salt and drinking alcohol are 47.28%, 24.15%, 47.79% and 44.90%, respectively), diagnosis and treatment(The symptoms, prognosis, screening methods, medication time and follow-up screening time of osteoporosis were 26.87%, 17.88%, 21.77%, 6.65% and 15.99%, respectivel) and prevention(exercise mode, high calcium food, optimal age of calcium supplementation, the effect of vitamin D on OP, and the appropriate amount of milk to prevent osteoporosis were 33.16%, 42.01%, 13.27%, 12.07%, 9.01%, respectively) were in Jiuting Town. In conclusion, the prevalent rate of OP in the elderly ≥60 years old in Jiuting Town is 45.89%.The main risk factors are female and advanced age. Drinking tea, dairy products, combination of meat and vegetable, taking calcium, physical exercise and sun exposure were the protective factors for osteoporosis. The awareness rate of osteoporosis related knowledge is low, and health education should be strengthened in order to control and prevent the occurrence and development of osteoporosis.

Objective:To evaluate the perioperative and follow-up data of carotid artery stenting (CAS)+ coronary artery bypass grafting (CABG) and CABG alone, and to assess the safety and efficacy of CAS in the treatment of severe stenosis of the carotid artery in combination with asymptomatic carotid artery stenosis.Methods:A retrospective analysis of 700 CABG patients combined asymptomatic carotid artery severe stenosis at Beijing Anzhen Hospital, Beijing Chaoyang Hospital, and Beijing Tiantan Hospital from January 2018 to December 2022 was performed. According to whether or not underwent CAS treatment, they were divided into the CAS-CABG group(116 cases)and the CABG-only group(584 cases). The mean age of the CAS-CABG group was (64.8±7.3) years, and all of them underwent unilateral CAS surgery only; the mean age of the CABG only group was (65.5±7.6) years. The main results of the patients in the two groups were compared at 30 days after the operation and follow-up period.Results:The early postoperative stroke rate was significantly lower in the CAS-CABG group(2.6% vs. 9.1%, P=0.02), while the combined procedure did not increase the rates of mortality and adverse events during follow-up. Subgroup analysis revealed that there was no significant difference in stroke rates between the two procedures for asymptomatic unilateral carotid artery stenosis, advanced age, history of atrial fibrillation, and history of stroke were independent risk factors for early stroke in CABG for asymptomatic unilateral carotid artery stenosis. Conclusion:CAS-CABG is safe and effective in the treatment of coronary artery disease combined with asymptomatic carotid artery stenosis, and can reduce the incidence of early postoperative stroke in patients. CABG patients with asymptomatic carotid stenosis should be rationally screened for prophylactic CAS to reduce the risk of postoperative stroke in these patients.

Osteosarcoma, a highly malignant tumor originating from bone tissue, is characterized by a high mortality along with a poor prognosis. The heterogeneity of the tumor microenvironment plays a pivotal role in its development and prognosis. Single-cell sequencing technology emerges as a crucial tool in elucidating this heterogeneity by delineating the functional characteristics and gene expression patterns of tumor cells, immune cells, and stromal cells within osteosarcoma tissues. This technology enables the depiction of the intricate interaction network between these cells. Utilizing the high-resolution advantage of single-cell sequencing, novel cell subtypes such as SPP1 (+) macrophages, C1QC (+) macrophages, and CLEC11A (+) B cells have been identified in osteosarcoma tissues, contributing to tumor growth and invasion within the tumor microenvironment. Identification of osteosarcoma stem cell subpopulations suggests that SERPINA1_CSCL1, FUS_CSCL2, and SPP1_CSCL3 populations may serve as the origin of osteosarcoma cells. Moreover, single-cell sequencing has revealed that mregDCs promote immune escape and tumor progression by selectively expressing CCR7, CCL17, CCL19, and CCL22 factors, thereby recruiting Treg cells. Additionally, this technology aids in the development of personalized chemotherapy regimens by pinpointing potential drug resistance targets in osteosarcoma, leading to the establishment of a drug resistance risk score model. In terms of disease prognosis, single-cell sequencing has identified immune infiltration-associated genes in osteosarcoma (e.g., EPHX2, FDPS, GBP1, MMD, ZYX), facilitating the construction of a prognostic analysis model for osteosarcoma patients, thus aiding in prognostic prediction.
