Smokers' intention and attempts to quit smoking in a district of Beijing Municipality / 预防医学

Objective@#To investigate the smoking cessation intention and attempt to quit smoking among smokers at ages of 15 years and older in a district of Beijing Municipality, so as to provide insights into formulation of tobacco control interventions. @*Methods@#Permanent residents at ages of 15 years and older were sampled using a multi-stage stratified cluster sampling method from a district in Beijing Municipality, and all smokers were recruited. Participants' demographic features, tobacco use, intention to quit smoking, attempts to quit smoking and awareness of tobacco-related hazards were collected using the Beijing Adult Tobacco Survey. The intention and attempts to quit smoking were analyzed among smokers, and factors affecting the attempt to quit smoking were identified using a multivariable logistic regression model. @*Results@#A total of 687 smokers were surveyed, including 669 men (97.38%), 497 from rural areas (72.34%), 351 daily smokers (51.09%), 336 occasional smokers (48.91%), 329 with intention to quit smoking (47.89%), and 178 with attempts to quit smoking during the past one year (25.91%). Univariable analysis showed that area, age, educational level, smoking status, tobacco health literacy and tobacco control information acquired from media were factors affecting intention and attempts to quit smoking among smokers (P<0.05). Multivariable logistic regression analysis showed that smokers with intention to quit smoking (OR=5.444, 95%CI: 3.585-8.268) and occasional smoking (OR=2.142, 95%CI: 1.312-3.497) were more likely to attempt to quit smoking. @*Conclusions@#Approximately half of smokers have intention to quit smoking in a district of Beijing Municipality; however, the percentage of attempts to quit smoking is low. Targeted interventions are required for smokers with different characteristics to improve the intention to quit smoking and promote smoking-quitting behaviors.

Risk assessment of unintention injury among preschool children in Shunyi District of Beijing / 中国学校卫生

Objective@#To understand the current situation and associated factors of unintentional injury among preschool children in Shunyi District, and to provide reference for the development of unintentional injury intervention measures.@*Methods@#Three kindergartens in Shunyi district were selected through stratified cluster sampling method, and all the parents were surveyed online by self-designed questionnaire.@*Results@#The proportion of low, medium and high risk assessment of unintentional injury in preschool children were 59.5%, 37.5% and 3.0%, respectively. Risk of unintentional injury increased significantly with age and grade(χ 2=12.35, 12.70, P<0.05). The risk of unintentional injury in inter-generational care (3.7%) was higher than that in parental care(2.4%). The higher the education level of the primary caretaker and family income, the higher level of unintentional injury risk(χ 2=11.23, 14.10, P<0.05).There were significant differences in the risk for burning, poisoning, other accidental injury, prevention of accidental injury and total score of unintentional injury among children of different ages and classes(F=8.26，5.61，4.95，6.15，7.86；9.88，8.39，4.25，6.27，7.55，P<0.05). There was statistical significance in burning risk between boys and girls(t=-4.27, P<0.05). There was statistical significance in unintentional injury prevention between children of different residence(t=9.11, P<0.05). There were significant differences in behavior supervision among risk among children of different ages and grades(P<0.05). Multiple linear regression analysis showed that education level of primary caregivers (college:B=-2.66, 95%CI=-4.69--0.63; bachelor degree or higher:B=-3.80, 95%CI=-5.90--1.70), annual family income (B=-2.82, 95%CI=-4.80--0.84) were associated with unintentional injury risk of preschool children(P<0.05).@*Conclusion@#Health education of unintentional injury prevention among preschool children should focus on the primary caretaker with low education and low family income, which is crucial for prevention of children s injury.

Use of contrast-enhanced ultrasound in evaluating the efficacy and application value of microwave ablation for adenomyosis

Aim: This study aims to assess the use of contrast-enhanced ultrasonography (CEUS) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in the evaluation of percutaneous microwave ablation (PMWA) of localized adenomyosis. Materials and Methods: Sixty-six patients with single-onset adenomyosis who underwent PMWA at the Liaocheng Tumor Hospital of Shandong Province from January 2013 to February 2019 were enrolled. Venous CEUS and DCE-MRI examinations were performed before and 1-2 days after the surgery. The ablation rates calculated by CEUS and DCE-MRI were compared and analyzed for accuracy. Results: After microwave ablation (MWA), CEUS showed that the volume and ablation rate of the ablated zone were 52.03 ± 28.39 cm3 and 90.90% ±6.61%, respectively. By DCE-MRI, the ablation volume and ablation rate of adenomyosis were 52.20 ± 28.65 cm3 and 90.88% ±6.32%, respectively. Dysmenorrhea was significantly relieved within 3 months of the operation, and nonmenstrual hemoglobin levels were significantly improved at 3 and 6 months after the operation (P < 0.05). All 66 cases of adenomyosis were treated using PMWA. Postoperatively, 17 patients reported a change in vaginal fluid; however, no special treatment was required as this disappeared 2-11 days after surgery. Conclusions: CEUS can accurately evaluate the ablation rate of localized adenomyosis treated with MWA, which is consistent with DCE-MRI. It is convenient and easy to perform ablation of adenomyomas, with incomplete ablation and angiography, and is a method worthy of clinical promotion

The number of students surveyed each year was 1 520, 1 404 and 1 467 respectively.@*Results@#A total of 4 500 questionnaires were distributed and 4 391 questionnaires were valid, with an effective rate of 97.6%. The current smoking rate and the attempting smoking rate in Shunyi District junior high school students increased substantially, the difference was statistically significant(χ2=9.15, 11.54, P<0.01). The exposure rate of second-hand smoke among junior high school students in Shunyi District is increasing year by year. The current smoking rate and the attempting smoking rate of second-hand smoke at home and in public places were higher than those of non-exposed ones. The differences in the current smoking rates of junior high school students (χ2=25.86, 37.61, P<0.01) and the attempting smoking rate (χ2=49.51, 63-86, P<0.01) were statistically significant. The influence of Shunyi District junior high school students through different tobacco information access channels on the current smoking rate of junior high school students increased year by year. Different tobacco information access channels have significant difference in the influence of the junior middle school students’ attempting smoking rate(P<0.05).@*Conclusion@#The overall tobacco use of junior high school students in Shunyi District of Beijing is increasing by year. The exposure of second-hand smoke is not optimistic, and the supervision of tobacco information acquisition channels is urgent to be strengthened.

A treatment method for chronic suppurative lacrimal canaliculitis using chalazion forceps.

Purpose: The purpose of this study is to evaluate the effectiveness of chronic suppurative lacrimal canaliculitis treatment using chalazion forceps. Patients and Methods: A prospective study was performed on consecutive patients who accepted the aid of chalazion forceps to treat chronic suppurative lacrimal canaliculitis. Two different treatment methods using chalazion forceps were performed according to the degree of lacrimal canaliculitis. Postoperatively, the patients received 0.5% levofloxacin eye drops four times per day and 0.5 g oral levofloxacin tablets once per day for 4 days. The follow‑up period was more than 3 months. Lacrimal irrigation, the condition of the lacrimal punctum, and patients’ symptoms were carefully evaluated. Results: In total, 32 patients met the criteria for chronic suppurative lacrimal canaliculitis. Included were 6 males and 26 females. Their average age was 51.7 ± 14.9 years (range; 19–80 years), and all had unilateral canaliculitis. The mean duration of the symptoms was 18.9 ± 9.8 months (range; 3–48 months). The mean follow‑up time was 14.7 ± 7.8 months. The signs and symptoms resolved completely in all patients within 15 days, and no recurrence was observed. No patients reported epiphora after the treatment. Conclusions: The use of chalazion forceps is effective in treating chronic suppurative lacrimal canaliculitis. The forceps may offer an alternative treatment technology in the management of suppurative lacrimal canaliculitis.
