Objective To evaluate the effect of applying emergency care simulator (ECS)on cardiopulmonary resuscitation skill training. Methods Clinical doctors and nurses(n=1 472)received the skill training of unarmed cardiopulmonary resuscitation (CPR),electric defibrillation and tracheal intubation by using simple CPR simulator (n=667)or ECS (n=805)respectively. After training,the examination was carried out and questionnaires were handed out. The completion time of operations, the scores and pass rates of examinations,the evaluations of training methods were compared between the two groups. The statistical data were analyzed by t(t')-test or Chi-square test with SPSS 19.0 and P <0.05 was considered as the criterion of significance. Results Compared with those of group using simple CPR simulator,the group using ECS showed obviously shortened completion time((309±125)s vs. (242±61)s,t'=12.65,P=0.00;(87±36)s vs. (55±31)s,t'=20.28,P=0.00;(239±87)s vs. (145±53),t'=24.4,P=0.00),significantly increased scores ((83.5±14.8)vs. (90.2±17.6), t'=7.93,P=0.00;(84.7±19.3)vs. (92.1±21.5),t'=6.95,P=0.00;(81.6±15.3)vs. (89.6±13.5), t'=10.53,P=0.00)and pass rates of examinations (84.1%(561/667)vs. 92.5%(745/805),χ2=25.96, P<0.01;82.2%(548/667)vs. 91.2%(734/805),χ2=26.41,P<0.01;80.8%(539/667)vs. 91.4%(736/805),χ2=35.48,P<0.01)as well as higher evaluation of training methods. Conclusions Application of ECS can obviously improve the training effect of CPR and it can be widely popularized in the edu-cation and training of emergency medicine skills.

Objective : To analyze the trends in incidence of thyroid cancer in Huangpu District, Shanghai from 2002 to 2017, so as to provide insights into the management of thyroid cancer. Methods : The incidence of thyroid cancer in Shanghai from 2002 to 2017 was collected from the cancer registration system created by Shanghai Center for Disease Control and Prevention. The crude and standardized incidence of thyroid cancer were estimated by year, gender and age groups, and annual change percentage ( APC ) was calculated to analyze the trends in incidence of thyroid cancer. Results : A total of 2 854 new cases of thyroid cancer were reported in Huangpu District from 2002 to 2017, and the crude and standardized incidence rates of thyroid cancer were 19.57/105 and 13.47/105, with APC of 18.15% and 17.93% ( P<0.05 ), respectively. The crude and standardized incidence rates of thyroid cancer were 10.02/105 and 7.06/105 in men, with APC of 19.58% and 19.04% ( P<0.05 ), and were 28.90/105 and 19.95/105 in women, with APC of 17.33% and 16.99% ( P<0.05 ), respectively. The crude incidence of thyroid cancer was higher in women than in men ( P<0.05 ). In addition, there were two peaks in the crude incidence of thyroid cancer in patients at age of 35 to 39 and 60 to 64 years, with crude incidence rates of 28.98/105 and 33.36/105, respectively. Conclusions The incidence of thyroid cancer appeared a tendency towards a rise in Huangpu District from 2002 to 2017, and much attention should be paid to females and patients aged 60 to 64 years.

OBJECTIVE: To observe the surgical therapeutic effects of dacryorhinocystotomy under nasal endoscope combined with the application of modified silicone mold implantation for postoperative recurrent dacryocystitis. METHOD: The research method is to conduct the dacryorhinocystotomy under nasal endoscope to 23 cases(24 eyes) of recurrent dacryocystitis, in the process of which modified silicone mold is implanted under the nasal mucosa. RESULT: During a follow-up of 6-12 months to the 23 cases (24 eyes), 18 eyes were cured, 6 eyes were getting setter and there was no recurrence. CONCLUSION It's concluded that the modified silicone mold implantation can avoid the recurrent atresia of the aperture created by the dacryorhinocystotomy, which proves that the combination with the modified silicone mold implantation in dacryorhinocystotomy is an effective treatment method of curing recurrent dacryocystitis.

Objective: To investigate the availability and use of child safety seats among children aged 0-3 years, so as to provide the basis for improving riding safety for children. Methods: Parents of children aged 0-3 years in Huangpu District, Shanghai Municipality, were recruited using the stratified multistage random sampling method from May to July 2024. Demographic information, family travel patterns, the use of child safety seat and related health beliefs were collected using questionnaire surveys. Factors affecting the use of child safety seats were identified using a multivariable logistic regression model. Results: Totally 514 valid questionnaires were recovered, with an effective rate of 96.98%. The respondents included 122 fathers (23.74%) and 392 mothers (76.26%), with a median age of 34.00 (interquartile range, 5.00) years. There were 446 families equipping with child safety seats, accounting for 86.77%; and 169 families using child safety seats, accounting for 32.88%. Multivariable logistic regression analysis showed that the parents who had children aged >1-2 years (OR=0.597, 95%CI: 0.366-0.973), travelled 2-4 times per month (OR=0.359, 95%CI: 0.213-0.607) or once per month or less (OR=0.384, 95%CI: 0.202-0.729), and scored high in perceived barrier (OR=0.634, 95%CI: 0.486-0.827) were less likely to use child safety seats; the parents who had children with local household registration (OR=2.506, 95%CI: 1.356-4.633), travelled 5-<10 km (OR=1.887, 95%CI: 1.148-3.101) or ≥10 km (OR=2.319, 95%CI: 1.355-3.967), always wore seat belts (OR=2.342, 95%CI: 1.212-4.524), scored high in perceived susceptibility (OR=1.392, 95%CI: 1.091-1.778) and self-efficacy (OR=1.413, 95%CI: 1.156-1.727) were more likely to use child safety seats. Conclusions Equipping family cars with child safety seats and using them can prevent and reduce traffic injuries among children aged 0-3 years. It is recommended to strengthen publicity to promote the use of child safety seats.

Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.
