Objective: To analyze the association between insufficient sleep and score of depressive symptoms among junior and senior high school students, so as to provide a scientific reference for targeted early intervention measures of adolescents depressive symptoms. Methods: From September to November 2023, a stratified cluster random sampling method was used to select 96 080 junior and senior high school students from 409 schools in 113 districts and counties in Shaanxi Province. A questionnaire survey was conducted using the 2023 Shaanxi Provincial Common Student Diseases and Health Influencing Factors Survey Form, and their height and weight were measured. Propensity score (PS) matched (1∶1) analysis was used to match participants with insufficient sleep to those sufficient sleep students. Through the gradual correction of the confounders, three multilevel linear models were established to analyze the association between insufficient sleep and depressive symptoms score, and subgroup analysis was conducted afterward. Results: A total of 70 135 (73.00%) students had insufficient sleep. After PS matching, 25 894 pairs were matched. Before PS matching, after adjusting for gender, educational stage, region, adolescent characteristics, boarding status, smoking, alcohol consumption, outdoor activities and body mass index grouping, linear regression analysis results showed that compared with students who got adequate sleep, students who lacked sleep had an increase of 1.39 scores ( B=1.39, 95%CI =1.28-1.51) in depressive symptoms; after PS matching, students with insufficient sleep got an increase of 1.32 scores ( B=1.32, 95%CI =1.17- 1.45 ) in depressive symptoms score compared with those who had adequate sleep (both P <0.05). Conclusions The insufficient sleep is associated with the increase of the depressive symptoms score of junior and senior high school students. It is recommended that junior and senior high school students should keep a good sleeping habit, so as to reduce the prevalence of depressive symptoms.

Objective: To analyze the trends, gender, and age differences in the incidence of lip and oral cavity cancer in Chinese population from 1990 to 2021 and predict future incidence trends, providing a scientific basis for disease prevention and public health policy. Methods: Incidence data of lip and oral cavity cancer in Chinese population from the Global Burden of Disease (GBD) database from 1990 to 2021 were analyzed. The Joinpoint regression model was used to assess temporal trends, the age-period-cohort model was used to evaluate the independent effects of age, period, and cohort, and the Bayesian age-period-cohort model (BAPC) model was used to predict incidence trends from 2022 to 2044. Results: From 1990 to 2021, the age-standardized incidence rate of lip and oral cavity cancer in Chinese population increased from 2.39/100 000 to 3.76/100 000, and the crude incidence rate rose from 1.71/100 000 to 4.85/100 000. The incidence rate in males was higher and increased more rapidly than in females. Higher incidence rates were prevalent among older populations, a rapid increase in incidence rates occurred during 2003 to 2012, and earlier birth cohorts showed overall higher risks. BAPC predictions indicated a continued rise in incidence from 2022 to 2044. During this period, male incidence stabilized while female incidence increased at a relatively faster rate. Conclusion The incidence of lip and oral cavity cancer in Chinese population has revealed a continuous upward trend, particularly among males and older populations. Future prevention strategies should focus on these high-risk populations.

OBJECTIVE: To explore the effects of different endotracheal tube cuff pressure management modes on cuff sealing and the pressure exerted on the tracheal wall. METHODS: A prospective self-controlled study was conducted. Eleven patients undergoing endotracheal intubation and mechanical ventilation with an automatic airway management system (AGs) admitted to the Second Medical Centre of the Chinese People's Liberation Army General Hospital from October 1, 2020, to April 1, 2022, were enrolled as the study subjects. Within 24 hours after the establishment of artificial airway and mechanical ventilation, four cuff pressure management modes were randomly applied to each patient for 24 hours in sequence: automatic cuff pressure management mode [modeI: the safe range of cuff pressure was set at 20-35 cmH₂O (1 cmH₂O≈0.098 kPa), and the CO₂ pressure above the endotracheal tube cuff was automatically detected by AGs every 5 minutes to determine the cuff sealing status, and the cuff pressure was automatically adjusted], constant cuff pressure (25 cmH₂O) management mode (mode II: the cuff pressure was monitored by AGs through a pressure sensor, and the cuff pressure was maintained at 25 cmH₂O via a pressure pump), constant cuff pressure (30 cmH₂O) management mode (mode III: the cuff pressure was monitored by AGs through a pressure sensor, and the cuff pressure was maintained at 30 cmH₂O via a pressure pump), and manual cuff pressure management mode (mode IV: the cuff pressure was manually measured by nurses every 6-8 hours using a cuff pressure gauge to keep the cuff pressure at 25-30 cmH₂O after inflation). The CO₂ pressure above the endotracheal tube cuff (at 60-minute intervals) and the cuff pressure changes (at 50-ms intervals) were recorded to compare the differences in number of cuff leaks [no leak was defined as CO₂ pressure = 0, small leak as 0 < CO₂ pressure < 2 mmHg (1 mmHg≈0.133 kPa), and large leak as CO₂ pressure ≥ 2 mmHg] and cuff pressure among modesI-IV. RESULTS: A total of 24 CO₂ pressure measurements were taken per patient across the four modes, resulting in a total of 264 detections for each mode. Regarding the cuff leak, the total number of leak and large leak in modeIwas significantly lower than that in modes II-IV [total leak: 30 cases (11.36%) vs. 81 cases (30.68%), 70 cases (26.52%), 103 cases (39.02%); large leak: 15 cases (5.68%) vs. 50 cases (18.94%), 48 cases (18.18%), 66 cases (25.00%), all P < 0.05]. There was no significant difference in the number of cuff leak between modes II and III, and mode IV had the most severe cuff leak. In terms of cuff pressure, since mode IV required blocking the cuff tube from the AGs tube and the AGs cuff pressure management module did not actually work, real-time monitoring of cuff pressure was not possible. Therefore, cuff pressure changes were only analyzed in modes I-III. Each of the 11 patients underwent 24-hour cuff pressure monitoring under modes I-III, with 19 008 000 monitoring times for each mode. The cuff pressure in mode I was between that in modes II and III [cmH₂O: 27.09 (26.10, 28.14) vs. 26.60 (25.92, 27.47), 31.01 (30.33, 31.88), both P < 0.01]. Moreover, the number of extreme values of cuff pressure > 50 cmH₂O in mode I was significantly lower than that in modes II and III [19 900 cases (0.105%) vs. 22 297 cases (0.117%), 27 618 cases (0.145%), both P < 0.05]. CONCLUSION Dynamically monitoring the CO₂ pressure above the cuff to guide the adjustment of endotracheal tube cuff pressure can achieve better cuff sealing with a relatively lower cuff pressure load.

Objective To investigate the impacts of fire needling combined with Huoxue Huayu Decoction on disease severity, skin barrier function and hemorheology in patients with psoriasis vulgaris of blood stasis syndrome. Methods A total of 120 patients with psoriasis vulgaris of blood stasis syndrome treated in our hospital were randomly divided into traditional Chinese medicine group (60 cases) and combined group (60 cases) according to the random number table method. The TCM syndrome scores, severity [Psoriasis Area and Severity Index (PASI) score], hemorheology (whole blood low shear viscosity and high shear viscosity, plasma viscosity), skin barrier function(transepidermal moisture loss, stratum corneum water content and sebum content), quality of life [Dermatology Life Quality Index (DLQI) score] and clinical healing effect were compared. Results Compared with before treatment, the scores of TCM syndromes such as hypertrophic infiltration of skin lesions, skin lesion color, pruritus, and skin dryness, PASI score, whole blood low shear viscosity, whole blood high shear viscosity, plasma viscosity, transepidermal water loss and DLQI score in both groups were decreased after treatment, and the degree of reduction in the combined group was more significant than that in the traditional Chinese medicine group(P < 0.05). Compared with before treatment, the water content and sebum content of the stratum corneum in both groups increased after treatment, and the combined group was higher than the traditional Chinese medicine group (P < 0.05). The total effective rate of the combined group was 93.33%, which was higher than 78.33% of the traditional Chinese medicine group (P < 0.05). Conclusion Fire needling combined with Huoxue Huayu Decoction for psoriasis vulgaris of blood stasis syndrome can usefully ameliorate the clinical symptoms and skin barrier function, regulate blood rheologyindexes, and enhance the quality of life.
