Objective To analyze the innovative model and effectiveness of the four-level prevention of stroke in Nantong Medical and Prevention Collaborative Center for Cardiovascular and Cerebrovascular Disease,so as to provide new practical experience for the prevention and treatment of cerebrovascular disease.Methods In practice,Nantong city has explored the"53343"mode of collaborative treatment and prevention of cardiovascular and cerebrovascular diseases,and innovatively integrated this mode into four-level prevention to form a practice mode of zero-level guidance,first-level monitoring,second-level coordination and three-level leading.Data from the China Health Statistics Yearbook from 2011 to 2022 and the monitoring data of cardiovascular and cerebrovascular events in Nantong City on the Jiangsu Provincial Chronic Disease Management Information Platform from 2017 to 2023 were collected and processed by using Excel and SPSS 24.0,to analyze the changes of stroke surveillance data and effectiveness in Nantong City after applying the model.Results According to the monitoring data of cardiovascular and cerebrovascular events in Nantong City from the Jiangsu Provincial Chronic Disease Management Information Platform,despite the continuous increase in the number of monitored individuals over five years,the monitoring data for stroke from the Nantong Medical and Prevention Collaborative Center for Cardiovascular and Cerebrovascular Disease witnessed a decline in the number of monitored individuals for the first time in 2022.The stroke monitoring data from the same monitoring agency showed a more stable fluctuation trend compared to the number of national stroke patients discharged from 2017 to 2021.We established a coherent health service operation mechanism,cultivated 14 interdisciplinary talents,held a special continuing education class on stroke,strengthened the in-depth collaboration between clinical and public health,and provided a practical and innovative model for effective prevention and treatment of stroke.Conclusions The four-level prevention based on the medical and preventive collaboration center for cardiovascular and cerebrovascular diseases can achieve process and cycle health management,effectively slow down the upward trend of stroke,and improve the ability and level of scientific research and teaching.

Objective:To understand the attitudes and cognition of disease control and prevention professionals at provincial level on public health physician standardized training and provide evidence for the improvement of the standardized training and exploration of more effective training mode in China.Methods:By cluster sampling, 2 193 professionals at provincial centers for disease control and prevention (CDC) in 6 provinces, including Jiangsu and Guangdong, Shanxi and Hubei,Sichuan and Xinjiang were selected as the study subjects, the sample size was estimated to be 1 933 persons.Results:A total of 1 716 provincial-level CDC professionals were surveyed, the support rate to the standardized training was 70.7%(1 213/1 716). The level of support was negatively associated with the educational level of professionals and their specialty of public health and preventive medicine. Of 875 public health and preventive medicine professionals, 61.6%(318/516) of those with master's degree or above supported the standard training for public health physicians, which was lower than 73.1%(225/308) of those with bachelor's degree and 86.3%(44/51) of those with college degree or below. There were 14.9%(232/1 555) of the respondents suggested a two year training, and 60.4%(933/1 544) suggesting a field training mode. In terms of training content, 86.6%(1 355/1 564) suggesting "epidemiological survey and public health practice", and 76.7%(1 199/1 564) suggesting "basic theories and methodology".Conclusions:In general, the professionals of provincial CDC showed a relatively low interest in the standardized training for public health physicians and failed to reach a consensus. Besides, they were ill-informed about current training duration, method and content. Thas, the professionals at provincial CDC are suggested to be the key target-population whom should be mobilized during the training pilot period, especially the highly educated ones with relevant specialties of public health. It is suggested that public health physician standardized training should to be implemented in whole CDC system to reach full consensus based on its practical achievements and effects. It is also suggested to establish public health graduate medical education system in China.

Under the background that the national health has become the national priority development strategy, it is essential to speed up public health ability among talents. Based on the consulting project of the Chinese Academy of Engineering, "Research on the training strategy of medical and health personnel in China", this paper analyzes the current situation and existing problems of public health personnel training in disease control and prevention institutions. Based on three stages of public health education, this paper puts forward that the public health personnel training should first solve the problem of public health personnel team construction and create programs on college education-post graduate education-continuing education. Through the personnel training system, different training modes are designed for other groups of people to improve the ability of public health personnel in an all-around way.

Retinoblastoma is the most common pediatric retinal tumor initiated by biallelic inactivation of the retinoblastoma gene ( RB1 ) , affecting roughly 1 in 15000 children with 1100 new cases each year.In China, RB remains a potentially devastating disease while lack of early diagnosis and aggressive treatment strategies.Moreover, RB patients individually show a variety of drug response to regular systemic chemotherapy since intensive chemotherapy and long-term follow-up are not as readily available.The majority of patients with advanced diseases require enucleation which affects the future quality of children life.Recent studies showed that alterations in genomics and epigenomics of RB play very important roles in RB progress and therapy.We thereby review current understanding changes of genomics and epigenomics in RB as potential prognostic and therapeutic targets.

Objective To investigate the effect of PCIA with low-dose fentanyl on plasma endothelin (ET) after craniotomy. Methods 47 cases of selected craniotomy were divided randomly into two groups :experimental group (26cases) and control group (21cases) . Patients in experimental group were treated with PCIA (fentanyl 15ug/kg +ondansetron 8 mg+100 mL NS) but patients in control group were not given PCIA. Then HR,MBP, VAS, ET and side-effects were observed and compared between two groups before treatment and 0, 2, 4, 8, 12, 24, 48 h after treatment.Results In experimental group, HR was lower at 2, 4, 8, 12, 24 and 48 h after treatment than control group. MBP was lower at 0 and 2h after treatment in experimental group than control group. Plasma levels of ET were lower at 8, 24 and 48h after treatment in experimental group than control group. There were significant differences in VAS scores at 2,4,8,12,24 and 48 h after treatment between two groups. There was no significant differences in side reactions including consciousness, respiratory depression, vomiting and sedation between two groups. The incidence of nausea was higher in experimental group than control group. Conclusion PCIA with low-dose fentanyl after craniotomy has good analgesic effect and few side reactions, can reduce the formation of plasma endothelin, and then alleviate brain damage.
