Objective: To investigate trends in incidence and mortality of colorectal cancer in Nantong City, Jiangsu Province from 2013 to 2022. Methods: Data on incidence and mortality of colorectal cancer from 2013 to 2022 in Nantong City were collected through the Nantong City cancer registry. The crude incidence, crude mortality, average age at onset, and average age at death of colorectal cancer were calculated. Chinese population-standardized incidence, Chinese population-standardized mortality, Chinese population-standardized average age at onset and Chinese population-standardized average age at death were calculated using the age structure of the standard population from the Fifth National Population Census in 2000. Trends in incidence and mortality of lung cancer from 2013 to 2022 were evaluated using average annual percent change (AAPC). Trends in the Chinese population-standardized average age at onset and Chinese population-standardized average age at death of lung cancer from 2013 to 2022 were evaluated using the linear regression model. Results: From 2013 to 2022, the crude incidence and Chinese population-standardized incidence of colorectal cancer in Nantong City increased from 33.63/105 and 16.05/105 to 53.82/105 and 19.62/105, respectively, showing upward trends (AAPC=5.665% and 2.467%, both P<0.05). The crude mortality increased from 15.99/105 in 2013 to 25.65/105 in 2022, also showing an upward trend (AAPC=5.514%, P<0.05), while no statistically significant trend was found in the Chinese population-standardized mortality (P>0.05). The Chinese population-standardized incidence of colorectal cancer showed upward trends in both males and females (AAPC=2.666% and 1.790%, both P<0.05). The Chinese population-standardized mortality showed an upward trend in males (AAPC=1.966%, P<0.05), but no statistically significant trend was found in females (P>0.05). The crude incidence of colorectal cancer in the groups aged 40-<50 years, 50-<60 years, 60-<70 years, 70-<80 years, and ≥80 years showed upward trends (AAPC=4.045%, 2.833%, 2.300%, 1.948%, and 1.775%, all P<0.05), and the crude mortality in the group aged ≥80 years showed an upward trend (AAPC=3.240%, P<0.05). The average age at onset of colorectal cancer increased at an annual average of 0.156 years (P<0.05), while the trend in the Chinese population-standardized average age at onset was not statistically significant (P>0.05). The average age at death and the Chinese population-standardized average age at death increased at an annual average of 0.325 and 0.153 years, respectively (both P<0.05). Conclusions From 2013 to 2022, both the crude incidence and mortality of colorectal cancer in Nantong City showed upward trends. Males and individuals aged ≥40 years faced a higher risk of both incidence and mortality. It is recommended to implement comprehensive prevention and control measures targeting these high-risk populations to reduce the burden of colorectal cancer.

[Purpose]To analyze the incidence and mortality trends,and survival of gallbladder cancer in Nantong City of Jiangsu Province from 2013 to 2017.[Methods]The gallbladder cancer incidence and mortality data from 2013 to 2017 were collected from Nantong cancer registries.The crude incidence/mortality rates,age-standardized incidence/mortality rates by Chinese and world standard population(ASIRC/ASMRC,ASIRW/ASMRW)were calculated by sex,age and regions(urban and rural).Joinpoint software was used to analyze the incidence and mortality trends of gallbladder cancer.The observed survival rate and relative survival rate were calculated by using life table method and Ederer Ⅱ method.[Results]From 2013 to 2017,the gallbladder cancer crude incidence and mortality rates were 6.36/105 and 4.91/105,ASIRC and ASMRC were 2.62/105 and 1.94/105,respectively.The crude incidence and mortality,and ASMRC showed an upwards trend(all P＜0.05).The ASIRC for men and women was 2.43/105 and 2.83/105,the ASMRC for men and women was 1.74/105 and 2.16/105,respectively.ASIRC and ASMRC in women were higher than those in men.The ASIRC in urban and rural areas was 2.40/105 and 2.69/105,and the ASMRC was 1.61/105 and 2.05/105,respectively.ASIRC and ASMRC in rural areas were higher than those in urban areas.The average age of onset was 70.33 years old and the average age of death was 71.86 years old.The 5-year observed survival rate was 12.90％,and the 5-year relative survival rate was 14.47％.Both the 5-year observed survival rate and relative survival rate showed an upwards trend(both P＜0.05).[Conclusion]The incidence and mortality rates of gall-bladder cancer in Nantong City are relatively high and the survival rate is generally low.It is sug-gested that targeted prevention and control measures of gallbladder cancer in Nantong City should be strengthened,particularly in rural areas and for middle-aged and elderly women.

Objective:To explore the research hotspots and trends of nursing related to atrial fibrillation and stroke.Methods:Searched on the Web of Science core collection database, CiteSpace.5.8.R3 software was used to analyze the authors, publishing institutions, reference co-citations, and keyword clustering of the retrieved article.Results:A total of 241 articles were included. The number of published papers was increasing year by year, but the overall number of published papers was relatively small. There were many co-authors and close cooperation between institutions. Stroke, anticoagulant therapy, impact, guideline, disease management and nursing homes had become research hotspots.Conclusions:CiteSpace software can intuitively analyze the nursing research hotspots related to atrial fibrillation and stroke, and can provide a research reference for the nursing of atrial fibrillation and stroke-related brain-heart comorbid diseases in China.

Objective To get well-informed of the current status of emergency training in primary hospitals in Sichuan Province and to find weaknesses in the system in order to provide scientific basis for emergency knowledge and skills training.Methods A stratified random cluster sampling method as adopted and an anonymous questionnaire survey method was conducted to investigate the basic circumstances of the current training and the training needs of 1 000 emergency medical staff in 9 regions throughout Sichuan Province.Results The scope of the survey covered emergency doctors,nurses and technicians in hospitals of Grade Ⅱ,Grade Ⅲ and below.A total of 1 000 surveys were sent out and 983 were recovered.The questionnaire completion rate was 98.3％.The respondents mainly worked for more than 10 years,most of which with Bachelor degree,junior and intermediate titles.Results of the survey showed,63.1％ Most respondents have only one or two training opportunities per year.The training methods are mainly continuing education (59.0％,580 trips),training organized within the unit (58.5％,575 trips),and training organized by health administrative units (39.3％,386 trips).The main contents of the training are:basic professional skills learning (66.7％,655 trips),basic professional theoretical study (59.2％,582 trips),and new emergency technology (42.5％,418 trips),only 32.0％ of the respondents believe that these methods meet the practical needs.The main factors that influence participation in the training were:not be arranged by employer (36.2％,356 trips);the training was different from actual work (31.6％,311 trips);no replacement for work so they couldn't join training (29.8％,293 trips).The survey showed that the most desirable way of training is:practical application (60.1％,591 trips) and the most desirable training content is:emergency first aid knowledge (73.7％,724 trips).There were significant differences in case discussion,technical observation,academic lectures,special study trainingand learning methods in hospitals of different levels (P＜0.05),but there was no significant difference in the choice of professional practice methods (P＞0.05),and the selection of training contents was in emergency first aid knowledge,general medical knowledge and prevention and treatment of chronic diseases.There was no statistical difference in the selection of training contents of knowledge,infectious disease knowledge and department management knowledge (P＞0.05).There were significant differences in the choice of nursing knowledge training (P＜0.05).Conclusion The current situation showed a lack of first-aid knowledge and skills training for emergency personnel in Sichuan Province.The present situation of skill training can't satisfy the need of their desire to participate in training.It is urgent to develop a standardized,systematic and scientific training mode to improve the emergency first aid ability of primary medical and emergency personnel.

Objective To investigate the senescence of rat mesangial cells induced by Tert-Butyl hydroperoxide (tBHP) and the protective effect of probucol on senesecence. Methods Human glomerular mesangial cells(hGMC) were cultured in vitro and intervened by tBHP. The cell survival rate was observed by methyl thiazolyl tetrazolium( MTT). β-gal staining and cell cycle analysis were used to identify cell senescent status;transmission eletric microscopy was used to evaluate the ultra-microstructure of hGMC. Senescent-related indexes were detected after treatment with probucol. Results The cell survival rate with 30 μmol/L tBHP was (80. 12 ± 3. 25 ) % , the positive rate of β-gal staining was significantly higher in tBHP-induced cells (about 81% )than that of the control cells( P <0. 01). 86% of the cells was arrested at G0-G1 phase. Invagination of nucleus membrane and chromatin condensation at the nuclear margin in tBHP-induced cells was observed through transmission eletric microscopy. In the probucol intervented cells, the cell survival rate was higher than that of tBHP-induced cells (92. 68 ± 5.03) % vs. ( 80. 12 ± 3. 25) % (P < 0. 05 ). The positive rate of β-gal staining decreased to 45. 2%. The proportion of cell cycle stage was similar to the control cells.The change of morphous and ultrastructure was relieved. Conclusions tBHP can induce hGMC senescence in vitro and probucol may play a role in preventing hGMC senescence.
