Abstract@#Allergic diseases can occur in all systems of the body, covering the whole life cycle, from children to adults and to old age, can be lifelong onset and even fatal in severe cases. Children account for the largest proportion of the victims of allergic disease, Children s allergies start from scratch, ranging from mild to severe, from less to more, from single to multiple systems and systemic performance, so the prevention and treatment of allergic diseases in children is of great importance, which can not only prevent high risk allergic conditions from developing into allergic diseases, but also further block the process of allergy. At present, there is no consensus on the management system of allergic children in kindergartens and primary schools. The "Consensus on Allergy Management and Prevention in Kindergartens and Primary Schools", which includes the organizational structure, system construction and management of allergic children, provides evidence informed recommendations for the long term comprehensive management of allergic children in kindergartens and primary schools, and provides a basis for the establishment of the prevention system for allergic children.

@#Abstract: Objective To retrospectively analyze the individual dose monitoring of radiation workers in Chongqing City from 2016 to 2020, so as to provide scientific reference for occupational health monitoring and radiation protection. Methods Radiation workers who performed individual dose monitoring in Chongqing Center for Disease Control and Prevention from 2016 to 2020 were selected as the research objects, and the monitoring data were collected and analyzed. Results A total of 40 926 individuals were included in this study, with a total of 135 622 person-years. The average annual individual effective dose of radiation workers over the five-year period was 0.56 mSv. NR1 and NR5, the ratio of the number of works receiving annual individual does exceeding 1 and 5 mSv to the to the total monitor workers were 13.019% and 0.335%. The annual effective dose per capita in Chongqing City showed a trend of first decreasing, then increasing and then decreasing again over the study period, with significant differences between different years (F=971.754, P<0.001). Although there were some differences in the variation trend of annual effective dose among different occupational categories, the overall trend was decreasing year by year. The average annual effective dose of nuclear medicine and interventional radiology was relatively high, and the difference was not statistically significant (P>0.05). The average annual effective dose of industrial flaw detection and accelerator operator in industrial application was relatively higher, and the difference was not statistically significant (P>0.05). There were statistically significant differences in the per capita effective doses of different occupational categories of medical application in different years (F=8.892-682.852, P<0.001). Among them, the per capita annual effective doses of five occupational categories of medical application were the highest in 2016, and the per capita annual effective doses of interventional radiology were the highest in 2018 and 2019. Conclusions The per capita annual effective dose of radiation staff in Chongqing has decreased year by year from 2016 to 2020, and remained at a relatively low level that meets national standards. The monitoring results suggest that the radiation staff of nuclear medicine, interventional radiology, industrial non-destructive testing and accelerator operator should give special attention to protect their occupational health and safety.

ObjectiveTo discuss the effect of patient controlled epidural analgesia on recovery and serum prolactin of parturient after undergoing cesarean section.MethodsEighty-six cases with cesarean section patients were classified into two groups by random digits table,which observation group with 43 cases were used patient controlled epidural analgesia,and control group with 43 cases were used intramuscular pethidine.The analgesic effect and serum prolactin between the two groups were compared.ResultsThe good rate in observation group was 79.1％(34/43 ),significantly higher than that in control group [20.9％( 9/43 ) ](P ＜ 0.05 ).Compared with pre-operation,the level of prolactin in observation group was significantly increased [ ( 542.17 ± 46.75 ) μ g/L vs.( 351.13 ± 20.92 ) μ g/L] ( P ＜ 0.05 ).Moreover,the level of prolactin in observation group after operation was significantly higher than that in control group[ (362.12 ± 24.33)μ g/L ] ( P ＜ 0.05 ).The colostrum time in observation group was ( 15.21 ± 3.26 ) h which was shorter than that in control group [ (21.16 ± 4.78) h ] (P ＜ 0.05).ConclusionThe analgesic effect of patient controlled epidural analgesia on parturient after undergoing cesarean section is good,which can help patients recovery and improve the level of serum prolactin,which can be applied in clinic.

<p><b>OBJECTIVE</b>To analyze the results of stage I and II tongue squamous cell carcinomas treated with different treatment modalities.</p><p><b>METHODS</b>The clinical data of 103 patients with stage I and II primary tongue squamous cell carcinoma treated with surgery or radiotherapy alone or combined modality therapy were reviewed retrospectively. The treatment results were compared by Log-rank test, Kaplan-Meier and Chi square test among three groups: surgery alone (S), radiotherapy alone (R) and combined modality therapy (surgery plus preoperative or postoperative radiotherapy, R + S/S + R), and the prognostic factors were also analyzed using Cox regression models.</p><p><b>RESULTS</b>The overall 5-year survival rate (OS) was 82.4% for stage I and 80.0% for stage II disease (P = 0.361). The 5-year survival rates of S, R and R + S/S + R groups were 90.3%, 68.4%, and 84.0%, respectively (P = 0.104). The local recurrence rates of those three groups were 2.5%, 35.7% and 5.7%, respectively (P < 0.001). Occult lymph node metastasis rate was 23.8%, frequently metastasized to level II lymph nodes. The patients with poorly differentiated carcinoma were found to have the highest regional recurrence rate. Local and regional recurrence was revealed as an independent prognostic factor.</p><p><b>CONCLUSION</b>Surgery alone can achieve good treatment result for stage I and II tongue squamous cell carcinomas, and lymph node dissection of level I to IV in the neck is recommended.</p>
