ObjectiveTo comprehensively analyze the disease burden of respiratory cancers in China from 1990 to 2021, and predict the trend of disease burden changes from 2022 to 2031, in order to improve its prevention and treatment strategies. MethodsData from the Global Burden of Disease (GBD) 2021 database were extracted and analyzed for the disease burden of nasopharyngeal cancer, laryngeal cancer, and tracheal, bronchial and lung cancers (hereinafter referred to as lung cancer) in China from 1990 to 2021. The Joinpoint 4.9.1.0 software was utilized to analyze the corresponding trends. The grey prediction model [GM (1,1)] was employed to forecast the disease burden of respiratory cancers in China from 2022 to 2031. ResultsThe disease burden of respiratory cancers attributed to tobacco and occupational carcinogens in China raised year by year from 1990 to 2021. Among the respiratory cancers, lung cancer led in terms of incidence, mortality, and disability-adjusted life years (DALY) and their respective age-standardized rates from 1990 to 2021, followed by nasopharyngeal cancer, with laryngeal cancer being the lowest. Analysis via the Joinpoint regression model indicated that, overall, the disease burden of nasopharyngeal and laryngeal cancers in China decreased during this time period, while that of lung cancer increased. From a gender perspective, the disease burden of male patients with nasopharyngeal, laryngeal, and lung cancers was significantly higher than that of female patients from 1990 to 2021. Compared to the global average, the disease burden of respiratory cancers in China from 1990 to 2021 was still relatively heavy. As of 2021, the middle-aged and elderly population above 50 years old was the primary group suffering from the disease burden of respiratory cancers in China. The prediction model showed that the age-standardized rate of nasopharyngeal cancer in China would decline from 2022 to 2031; the age-standardized incidence rate of laryngeal cancer in China would increase, while its age-standardized mortality rate and DALY rate would both decrease; the age-standardized rates of lung cancer in China would all increase. ConclusionIn the past 30 years, the disease burden of nasopharyngeal and laryngeal cancers in China has lightened, but the overall disease burden of lung cancer is still on the rise. Compared to the global average, the disease burden of respiratory cancers in China is still relatively heavy. The disease burden in male patients is significantly higher than that in female patients, and the population above 50 years old is the main group suffering from the disease burden. In the next 10 years, the disease burden of respiratory cancers in China will still tend to increase. Therefore, targeted prevention and treatment strategies for men and the middle-aged and elderly populations remain key challenges that urgently need to be addressed in China's response to respiratory cancers.
Objective To investigate the current status of fear of disease progression and sleep quality among laryngeal cancer patients, and analyze the correlation between them. Methods Laryngeal cancer patients who were hospitalized in West China Hospital of Sichuan University between March 2021 and February 2022 were selected for this cross-sectional survey. Sociodemographic and disease-related data questionnaires, Chinese version of Fear of Progression Questionaire Short Form, and Pittsburgh Sleep Quality Index (PSQI) Scale were used to investigate the laryngeal cancer patients who met the inclusion criteria, and the correlation between fear of disease progression and PSQI score in laryngeal cancer patients was analyzed by Spearman correlation analysis. Multiple linear stepwise regression analysis was used to analyze the effects of sociodemographic and disease-related characteristics on the total score of fear of disease progression in laryngeal cancer patients, and the effects of sociodemographic, disease-related characteristics and total score of fear of disease progression on the total score of PSQI of laryngeal cancer patients. Scores were expressed as median (lower quartile, upper quartile). Results A total of 312 copies of questionnaires were distributed and 309 valid copies were recovered, with an effective recovery rate of 99.0%. The total score of fear of disease progression in the laryngeal cancer patients was 22.00 (16.00, 30.00), including 12.00 (8.00, 17.00) in physiological health dimension, and 10.00 (7.00, 14.00) in social and family dimension. The total score of PSQI was 5.00 (3.00, 8.50). The correlations of the physiological health dimension score, the social and family dimension score, and the total score of fear of disease progression with the total score of PSQI in laryngeal cancer patients were positive with statistical significance (rs=0.294, P<0.001; rs=0.234, P<0.001; rs=0.287, P<0.001). Multiple linear stepwise regression analyses showed that the total score of fear of disease progression in laryngeal cancer patients was affected by the stage of disease, occupation, primary caregiver and treatment plan (P<0.05), and the total score of PSQI of laryngeal cancer patients was affected by level of education, treatment plan and the total score of fear of disease progression (P<0.05). Conclusions The fear of disease progression in laryngeal cancer patients has a significant negative correlation with the sleep quality. Meanwhile, alleviating the level of fear of disease progression may improve sleep quality.

Methods : From March 2008 to July 2009, 24 Balb/c nude mice were randomly divided into three groups: BQ123 group ［〖WTBX〗n =8, BQ123 at 2mg/(kg·day)］, 5Fu group ［〖WTBX〗n =8, fluorouracil at 2mg/(kg·day)］ and the control group (〖WTBX〗n =8, normal saline). The carcinoma volume and microvascular density of each group were compared. Results : The tumor size of BQ123 group, which was (162±053)cm3 in average, was significant smaller than the tumor sizes of the other two group s. The average microvascular density score of the tumors in BQ123 group was 232 per hyper power len (HP), which was also significantly less than the average scores of control groups (586 and 395 respectively). Conclusion : Nude mouse experiments show that the carcinoma volume and microvascular density of BQ123 group are significantly lower than those of the control groups. BQ123 inhibits the growth of carcinoma by its inhibition of carcinoma angiogenesis.

Methods With the Hep-2 cells as the target cells and human normal laryngeal squamous epithelial cells (HNLE cells) as the absorber cells, 3 rounds of panning from a Ph.D.-12TM phage-display peptide library were carried out. Ten randomly selected phage clones were sent for sequence detection. The affinity of phage clones was detected by enzyme-linked immunosorbent assay (ELISA). The positive phage clones (F2) specifically bound to Hep-2 were identified by immunofluorescence detection. Results After 3 rounds of screening, 5 positive phage clones showed specific binding to Hep-2 cells and the affinity of positive phage clones (F2) was significantly higher than that of the control groups (Plt;0.05). The results of immunofluorescence detection indicated that F2 could be specifically bound to Hep-2. Conclusions Phage display peptide libraries technique can successfully screen the peptide specifically bound to Hep-2 cell line. Thus, it provides a potential vector for targeting therapy of laryngeal squamous cell carcinoma patients.
From Nov. 1988 through Apr. 1994, 78 cases with laryngocarcinoma underwent laryngectomy and laryngeal reconstruction by the use of transfered cervical skin. Three to six months after operation, all patients were subjected to direct or indirect laryngoscope. It was found that the keratinized of layer of the transfered skin tended to be thining out, and that hair had grown in one case. With the followup ranging from 3 months to 5 years,the results were good. All patients following the reconstruction of larynx could phonate, swallow and breath. Postoperatively, 32 patients were alive for 3 years, 2 patients died from recurrence of laryngocarcinoma. The complications included laryngeal fistula in 6 cases and laryngostenosis in 2 cases. The cause as well as the prevention of complications were discussed. It was suggested that thetransfer of cervical flap was feasible for laryngeal reconstruction.
目的:探讨改良气管套管垫安置法对喉癌术后佩戴气管套管、颈部伤口敷料加压包扎期患者的适用性。方法:采用随机分组的方法将38例喉癌术后佩戴气管套管的患者分为传统组20人和改良组18人, 传统组采用“Y”型气管套管垫,改良组采用“Y”型气管套管垫,比较两组患者在更换气管套管垫时的SpO2值、SpO2降低值及刺激性咳嗽次数。结果:安置气管套管垫的过程中,改良组SpO2值高于传统组、SpO2降低值低于传统组,且发生刺激性咳嗽的次数也低于传统组,差异有统计学意义(Plt;0.01)。结论:与传统气管套管垫安置法相比,改良气管套管垫安置法能减少患者换药过程中刺激性咳嗽的次数,对SpO2值影响轻微,更适合于喉癌术后早期颈部伤口敷料加压包扎患者的换药。
