[Analysis on the status quo of the awareness rate of core knowledge of cancer prevention and treatment and its influencing factors among residents in Liaoning Province in 2021]

Objective: To analyze the status quo of the knowledge and related factors of cancer prevention and treatment among residents in Liaoning Province in 2021. Methods: From August to November 2021, through network sampling method, 17 474 permanent residents aged 15-69 years in Liaoning Province were surveyed. The WeChat public account was used to collect information such as demographic characteristics and core knowledge of cancer prevention and treatment. The Chi-square test was used to compare the difference of the level of the cancer prevention and treatment knowledge among different groups. The multivariate logistic regression model was used to analyze the related factors. Results: Among the 17 474 subjects, 43.1% (7 528) were male and 58.7% (10 262) were urban residents. The overall awareness rate was 72.3%, and the awareness rate of cancer cognition, prevention, early diagnosis and treatment, cancer management and rehabilitation were 71.4%, 67.6%, 72.7%, 83.4% and 63.5%, respectively. The multivariate logistic regression model showed that the residents who were man (OR: 0.850, 95%CI: 0.781-0.925), in rural areas (OR: 0.753, 95%CI: 0.694-0.817), 55-59 years old (OR: 0.851, 95%CI: 0.751-0.963), quitters (OR: 0.721, 95%CI: 0.640-0.813) and smoker (OR: 0.724, 95%CI: 0.654-0.801) had lower awareness rates, while the residents who were 35-54 years old (OR: 1.312, 95%CI: 1.202-1.432), with an educational level of junior high school/senior high school/college degree or above (OR: 1.834-5.130, 95%CI: 1.575-6.047), technical personnel (OR: 1.592, 95%CI: 1.367-1.854), civil servant/institution staff (OR: 1.282, 95%CI: 1.094-1.503), enterprise/business/service staff (OR: 1.218, 95%CI: 1.071-1.385), retired (OR: 1.324, 95%CI: 1.114-1.573) and with family history of cancer (OR: 1.369, 95%CI: 1.266-1.481) had higher awareness rates. Conclusion: The level of the awareness of core knowledge of cancer prevention and treatment among residents in Liaoning Province has met the requirements of the Healthy China Action. Region, gender, education level, age, family history of cancer and smoking are relevant factors.

[Postoperative effects of balloon sinuplasty on chronic rhinosinusitis: a Meta-analysis]

Objective: To evaluate the postoperative clinical effects of balloon sinuplasty on chronic rhinosinusitis. Methods: PubMed, OVID, Embase, Cochrane Library, Proquest, Web of Science, Sinomed, Wan Fang and CNKI database (from established time to March of 2017) were searched for trials about the chronic rhinosinusitis treated by balloon sinuplasty. The relavent literatures were screened, and the prospective control studies were chosen. Lund-Mackay and SNOT-20 scores were used as the outcome idicators, and the methodological quality of the literatures were evaluated strictly. The extracted data were analyzed by Revman 5.3 software. Results: A total of 7 prospective before-after self-controlled studies were included, and the overall quality of which was relatively high. Meta-analysis showed that the Lund-Mackay scores at 6 months post-operation, the SNOT-20 scores at 6 months and more than 1 year post-operation were significant lower than baseline when balloon sinuplasty used in the surgery; the SNOT-20 scores at more than 1 year post-operation was lower than baseline when a standalone ballon sinuplasty was performed. All the results was statistically significant (P<0.05), and all the SMD were more than 0.8. Conclusions: The postoperative effect of balloon sinuplasty on chronic rhinosinusitis is obvious, and the subjective symptoms in patients is relieved effectively.

[Drug-taking behavioral analysis in patients with allergic rhinitis]

Objective:To analyze the drug-taking behavior of patients with allergic rhinitis, and the relationship with the severity of the symptoms.Method:A total of 1 621 sets of data in 66 patients with allergic rhinitis were enrolled in this study, who filled out the daily symptom score scale and daily medication score scale for 5 days or more. The symptoms include sneezing, rhinorrhea, nasal itching, nasal congestion, eye itching/foreign body sensation/red eyes and watery eyes were scored. The medications include antihistamines, nasal glucocorticoid, oral glucocorticoid, β2 receptor agonists and inhaled glucocorticoid were scored.Result:In the 1 621 sets of data, the highest incidence of symptoms was sneezing, 50.77%, the highest incidence of moderate to severe symptoms was rhinorrhea, 10.06%. The drug-taking behavior was 827 times, and the drugtaking rate was 51.02%. Antihistamines had the highest use ratio, 73.64%, followed by nasal glucocorticoid, 49.33%. There was no direct relationship between the total symptom score and the drug-taking rate, nasal glucocorticoid use ratio. Compared with the group of continuous drug-taking less than 2 weeks, the total symptom score of the group of continuous drug-taking more than 2 weeks was significant low.Conclusion:The number and continuity of the drugtaking in patients with allergic rhinitis vary greatly. Patient education is needed.

Comparison of the effects of nitrendipine and captopril on the regression of hypertensive left ventricular hypertrophy

To compare the efficacy of new calcium blocker nitrendipine and ACE-inhibitor captopril on the regression of hypertensive left ventricular hypertrophy (LVH), 134 hypertensive subjects with LVH were divided randomly into two groups. 2DE, M-mode and pulsed Doppler echocardiography was used to measure the left ventricular structure and function. In the nitrendipine group (n = 67, mean age 48 +/- 11 years), nitrendipine (20-40 mg/day) was administered for 24 months, and in the captopril group (n = 67, mean age 47 +/- 12 years), captopril (75-150 mg/day) was also given for 24 months. Blood pressure decreased significantly in all the patients. In the nitrendipine group, the thickness of the interventricular septum (IVST) and the posterior wall of the left ventricle (PWT) as well as the left ventricular mass index (LVMI) decreased by 20.3%, 15.5% and 25.7% (P less than 0.01) respectively. The cardiac index (CI), left ventricular ejection fraction (EF) and fractional shortening (FS) remained unchanged. The early peak filling velocity (E, 0.64 +/- 0.15 to 0.86 +/- 0.22, P less than 0.01) of the mitral valve and E to late peak filling velocity ratio (E/A, 0.88 +/- 0.20 to 1.31 +/- 0.31, P less than 0.01) increased significantly. In the captopril group, IVST, PWT, and LVMI were 20%, 17.1% and 23.6% respectively (P less than 0.01). CI (2.6 +/- 0.5 to 3.7 +/- 0.6L/min/m, P less than 0.01) and EF (60 +/- 4 to 78 +/- 6%, P less than 0.01) increased. Both E and E/A were elevated in a similar degree as in the nitrendipine group.(ABSTRACT TRUNCATED AT 250 WORDS)
