Objective:To understanding the epidemiological characteristics of self-injury/suicide among residents in Jiangsu Province, as well as grasping the current situation and patterns, will provide support and a basis for reducing the occurrence of self-injury/suicide harm.Methods:Data on self-injury/suicide cases from 2006 to 2022 were collected from 12 national injury surveillance sentinel hospitals in Jiangsu Province. The prevalence characteristics were analyzed using R 4.2.1 software, employing the chi-square test and Post Hoc testing for pairwise comparisons between groups, with adjusted standardized residuals to assess group differences.Results:From 2006 to 2022, there were 5 504 cases of self-injury/suicide monitored in Jiangsu Province, comprising 2 016 males and 3 488 females, resulting in a male-to-female ratio of 1∶1.73. The top three months for self-injury/suicide incidents were June (10.12%), May (9.85%), and July (9.25%). The peak times for these incidents were between 00:00-01:00 and 20:00-21:00. The majority of self-harm/suicide incidents occurred at home (73.64%). The primary methods of self-harm/suicide were poisoning and injuries caused by sharp objects, accounting for 47.11% and 35.32%, respectively. The frequently injured body parts were the upper limbs (34.97%) and generalized injuries throughout the body (25.56%). In terms of severity, mild cases predominated (49.78%). Further analysis reveals that, compared to male, self-harm/suicidal characteristics, female self-harm/suicidal behavior is more likely to occur at home, with poisoning as the predominant method, injuries affecting multiple body areas, and the severity of injuries being relatively mild ( P<0.001). In the 15-29 age group, self-harm/suicidal injuries predominantly affect the upper limbs ( P<0.001). Self-harm/suicidal behavior is more likely to occur at home, with poisoning being the primary method, injuries affecting multiple body areas, and the severity of injuries being more severe (all P<0.001) for individuals aged 60 and above. Conclusions:To prevent and control self-harm/suicidal behavior and reduce the suicide mortality rate, it is essential to strengthen support and care for key populations such as women, those aged 15 to 29, and individuals aged 60 and above. Monitoring and management should be enhanced in key locations where self-harm/suicide is more likely to occur, such as homes, public living spaces, schools, and public areas, to enable early detection. Controlling potential methods of suicide is crucial, such as continuing to strengthen regulations and restrictions on highly toxic pesticides and reducing the likelihood of fatal overdoses from medications.

Objective:To understand the situation and epidemic characteristics of injury deaths among children aged 5 to 24 years in Jiangsu Province from 2012 to 2021 and the trend of annual changes.Methods:The main injury mortality data of children and adolescents was collected, and the crude and standardized mortality rates of road traffic accidents, drowning, suicide, and accidental falls among children and adolescents over a decade and the annual average percentage of change (AAPC) were calculated. The main injury mortality characteristics and trends of children and adolescents of different age groups and genders were analyzed.Results:The total number of injury deaths among 5 to 24 adolescents in Jiangsu Province was 16 052, with a standardized mortality rate of 9.58/100 000. There was no significant trend in the overall standardized mortality rate of injuries (AAPC=-3.450%, P=0.055). The standardized mortality rate of road traffic injuries among children and adolescents showed a decreasing trend over the past decade, with statistical significance (AAPC=-9.406%, P<0.001). The standardized suicide mortality rate showed an upward trend over the past decade, with statistical significance (AAPC=9.000%, P=0.001). The overall injury mortality rate showed an upward trend with age. Suicide rates in males and females were on the rise and both have statistical significance (AAPC=9.420% and AAPC=9.607%, both P<0.05). The standardized mortality rates of female traffic accidents, drowning, and male traffic accidents showed a decreasing trend and were statistically significant (AAPC for female traffic accidents=-7.364%, AAPC for female drowning=-5.352%, and AAPC for male traffic accidents=-10.242%, all P<0.05). The standardized mortality rate of urban and rural traffic accidents showed a decreasing trend and was statistically significant(AAPC=-7.899% and AAPC=-9.421%, both P<0.001). The standardized suicide mortality rate showed an upward trend and statistical significance (AAPC=11.009% and AAPC=7.528%, both P<0.05). Conclusions:The overall injury situation of children and adolescents in Jiangsu Province improved in the past decade from 2012 to 2021, but the suicide mortality rate was on the rise. It is necessary to focus on the mental health issues of this age group and to strengthen the prevention and control of suicide among children and adolescents, in Jiangsu.

Objective:To understand the epidemiological characteristics and trends of injury in older adults in Jiangsu Province from 2006 to 2022 and provide a scientific basis for developing prevention and control measures.Methods:The data on injury cases aged 60 and older were collected from 12 sentinel hospitals in Jiangsu Province during 2006-2022. The study analyzed the proportion of injury cases among the elderly in the overall population and calculated the annual percent change and average annual percent change (AAPC). A pairwise comparison between groups was performed, and the differences were judged according to the adjusted standardized residuals.Results:From 2006 to 2022, there were 218 426 injury cases among individuals aged 60 and older in Jiangsu Province, which accounted for an increasing proportion of injury cases within the entire population (AAPC=3.17%, P<0.001). The first five causes of elderly injury were falls (42.06%), road traffic injuries (20.20%), animal injuries (11.45%), knife/sharp injuries (9.43%), and blunt injuries (8.13%). From 2006 to 2022, the proportion of falls, animal injuries, and knife/sharp injuries among the elderly aged ≥60 showed an increasing trend, while the proportion of road traffic injuries and blunt injuries decreased (all P<0.001). The incidence of injury was highest in October, with a daily incidence peak between 8:00 and 10:00. Leisure activities (40.34%) were the major activity leading to injury. The injury occurred mainly at home (53.74%), and the injury intention was mainly unintentional (97.41%), all of which showed an increasing trend ( P<0.001). The injuries were mainly bruises (36.00%), and the most common injured positions of the body were low limbs (27.55%), all of which showed a decreasing trend ( P<0.001). About 69.80% of cases were slight, and 79.38% were discharged after treatment, which showed an increasing trend ( P<0.001). Conclusions:The injury data for individuals aged 60 and older in Jiangsu Province exhibited varying trends from 2006 to 2022. There was a noticeable increase in the proportion of elderly injury cases within the overall injury population, as well as an upward trend in falls, animal injuries, and knife/sharp injuries as leading causes of injury. It is imperative to actively develop prevention measures based on the epidemiological characteristics and evolving trends of elderly injuries in Jiangsu Province.

Objective:To analyze the comorbidity status and influencing factors of hypertension, diabetes, and dyslipidemia among middle-aged and elderly in Jiangsu Province and to provide support for "co-management of the three diseases".Methods:Data originated from the Comprehensive Prevention and Control Project of Cardiovascular and Cerebrovascular Diseases baseline survey in Jiangsu Province. Questionnaire interviews, physical examinations, and laboratory tests were conducted on 136 433 permanent residents aged ≥35 years who participated in the survey from 2021 to 2023. A multinomial logit model was established using SPSS 23.0 to analyze the influencing factors of the three comorbidities.Results:The comorbidity rate of hypertension, diabetes, and dyslipidemia among middle-aged and older adults in Jiangsu Province was 7.3%. Hypertension combined with dyslipidemia was the main comorbidity pattern, and patients with diabetes accounted for the largest proportion. Multinomial logistic regression analysis showed that the risk of being two types of the three comorbidities was higher in male, aging, urban residents, and those with high/technical secondary school, higher frequency of cigarette smoking and alcohol drinking, and longer daily sedentary time; the risk was lower in those with higher the level of physical activity and longer daily sleep time. Among the three types of comorbidities, males with aging, high/technical secondary school, regular smoking/quitting, higher frequency of alcohol drinking, and longer daily sedentary time had higher risk; those with an annual family income of 30 000-99 999 RMB, higher level of physical activity, and the daily sleep time of 7 hours had the lower risk (all P<0.05). Conclusions:The prevention and control of the three comorbidities among middle-aged and older adults in Jiangsu Province still needs strengthening. High-risk groups for the three diseases and comorbidities, such as males, low-income , and high/technical secondary school should be focused on. Middle-aged and older adults are suggested to increase daily physical activity, reduce daily static time, reasonably arrange sleep duration, and quit smoking and drinking as early as possible to maintain a healthy weight.

Objective:To understand the epidemiological characteristics and influencing factors of elderly unintentional fall-related injuries (EUFI) in Jiangsu from 2006 to 2021 and provide a scientific basis for the prevention of falls in the elderly and the formulation of related policies.Methods:Data on EUFI was collected from the first diagnosed cases in the injury surveillance hospitals in Jiangsu from 2006 to 2021, and epidemiological characteristics of injuries were analyzed. logistic regression was performed to identify the risk factors for EUFI.Results:The number of EUFI increased from 2006 to 2021, ranked as the first cause of elderly unintentional injuries during these years. The proportion of EUFI among elderly unintentional injuries increased in the same period. The male-to-female ratio is 1∶1.4. Falls mainly occurred during 8:00-10:00 am (32.7%). The most common place where falls occurred was at home (63.6%). From 2006 to 2014, leisure activities (62.1%), housework/study (23.1%), and work (5.2%) were the top three activities when injuries occurred. During 2015-2021, leisure activities (41.7%), housework/study (22.6%) and walking (20.5%) were the top three activities when injuries occurred. The major fall-related injuries were fractures (39.9%), with the injured parts at low limbs (32.5%), of which most were mild injuries (60.3%), and the primary outcome was hospitalization after treatment (74.1%). logistic regression showed that the risk factors of EUFI were female, old age, immigrants, winter, public residence, housework/study, and leisure activities. Higher education, occupation of household and production and transportation equipment operators were protective factors (all P<0.05). Conclusions:Fall is the leading cause of unintentional injuries in the elderly in Jiangsu, especially the elderly female population. Corresponding measures should be taken to prevent and intervene in falls in the elderly in the community according to the distribution characteristics.

Objective:To analyze the gene variants in patients with primary distal renal tubular acidosis (dRTA), and explore the correlation between the genotype and phenotype.Methods:The Sanger direct sequencing or whole-exome sequencing was used to identify causal variants and the variation pathogenicity was evaluated according to 2015 American College of Medical Genetics and Genomics (ACMG) standards and guidelines in 44 dRTA patients (37 families) diagnosed in the Affiliated Qingdao Municipal Hospital of Qingdao University and the Affiliated Hospital of Qingdao University from April 2010 to September 2020. The clinical features of the patients were summarized, and the correlation between the genotype and phenotype was investigated.Results:Seven variants of SLC4A1 gene, 17 variants of ATP6V0A4 gene, and 15 variants of ATP6V1B1 gene were identified in 44 patients with dRTA, and of which 11 variants were new ones. According to ACMG guidelines, the pathogenic, likely pathogenic, benign variants among the 39 variants were 22, 16 and 1, respectively. Nine patients were autosomal dominant hereditary dRTA caused by SLC4A1 gene mutation, 4 patients with autosomal recessive hereditary dRTA complicated with Southeast Asian ovalocytosis and anemia were caused by SLC4A1 gene mutation, and 14 patients caused by ATP6V0A4 gene mutation and 8 patients caused by ATP6V1B1 gene mutation were autosomal recessive hereditary dRTA; Two children with dRTA were found to carry one monoallelic defect in ATP6V1B1, and no causal gene mutation was identified in 7 patients. One patient showed incomplete dRTA, and the other 43 patients showed complete dRTA. The prevalence of sensory neural hearing loss caused by ATP6V0A4 and ATP6V1B1 mutation were 2/14 and 6/10 respectively. The frequency of chronic kidney disease in adults, children and infants were 4/4, 2/4, and 1/36, separately. After the drug treatment based on potassium citrate and sodium citrate, the growth and development (28/40) and electrolyte disturbance (41/44) of most patients were significantly improved. Conclusions:The present study has identified 39 variants of SLC4A1, ATP6V0A4 and ATP6V1B1 genes in 44 patients with dRTA, including 11 novel ones. There is a close relationship between genotype and phenotype in dRTA patients and most patients' conditions were improved after proper treatment. This study enriches the human gene mutation database and provides valuable references for diagnosis, treatment and genetic counseling in patients with dRTA.

Objective: To observe the effect of whole-body vibration therapy on the lower extremity the motor function of children with spastic diplegia. Methods: Fifty-six children with spastic diplegia were randomly divided into a treatment group and a control group, each of 28. Both groups were given routine rehabilitation exercise training, while the treatment group was additionally provided with 15 minutes of whole-body vibration therapy every day, 5 days a week for 12 weeks. Their GMFM-88 D (standing) and E (walking and jumping) scores were recorded before and after the treatment along with the active and passive range of motion of the ankle in dorsiflexion, and the root mean square surface electromyogram signals from the tibialis anterior and gastrocnemius muscles. Berg balance scale scores were also assigned before and after the treatment for both groups. Results: There were no significant differences between the two groups before the treatment. Afterward all of the evaluations except the signals from the tibialis anterior muscle in active ankle dorsiflexion had improved significantly. The improvements were all significantly better in the treatment group. Conclusion Whole-body vibration therapy can effectively improve the lower extremity motor function of children with spastic diplegia.

Objective: To investigate the prevalence, awareness, treatment and control of hypertension in adult residents in Jiangsu province and provide evidence for the prevention and control of hypertension. Methods: A population-based cardiovascular disease screening project was conducted during 2015-2018 in Jiangsu, a total of 95 348 community-dwelling adults aged 35-75 years from 6 project areas were included in the study. The prevalence rate of hypertension and rates of awareness, treatment and control of hypertension in the adults with different characteristics were analyzed. Multilevel model was applied to identify the influencing factors. Results: Among 95 348 adults surveyed, 54 407 were hypertensive, the standardized prevalence rate was 48.1%. The prevalence rate was significantly higher in males than in females (62.1% vs. 54.0%, P<0.05). Among the hypertension patients, the rates of awareness, treatment and control of hypertension were 56.6%, 45.3% and 12.0% (standardized rates: 52.2%, 41.0% and 11.2%), respectively, and all the rates were positively associated with age (all P<0.05). Multilevel model analysis showed that those who were males, at older age, lived in rural area, suffered from diabetes, had frequent alcohol drinking and those who were overweight/obese had higher risk for hypertension (all P<0.05). Among people with hypertension, those who had younger age, lower education level, lower household income level and those who had frequent alcohol drinking had lower awareness, treatment and control rates of hypertension (all P<0.05). Conclusions The prevalence rate of hypertension was high, but related awareness, treatment and control rates were low in adult residents in Jiangsu province. Comprehensive measures should be taken to improve awareness, treatment and control of hypertension in whole population, especially in young adults, and those with low education or income levels.

Objective: To understand the prevalence of carotid plaque (CP) in population at high-risk for cardiovascular disease (CVD) in Jiangsu province and identify related influencing factors. Methods: Based on the China Patient-centered Evaluative Assessment of Cardiac Events Million Persons Project from 2015 to 2016, a total of 11 392 persons at high-risk for CVD were selected from six project areas in Jiangsu province for the questionnaire survey, physical measurement, laboratory test and bilateral ultrasound examination of carotid arteries. The prevalence of CP and influencing factors of abnormal carotid arteries, CP and plaque burden (CP≥2) were analyzed. Results: Among the persons surveyed, 4 821 (42.3%) were males. The age of the persons surveyed was (59.4±8.9) years. There were 5 971 abnormal carotid arteries cases (52.4%), including 1 782 carotid intima-media thickness thickening cases (15.6%), 3 811 CP cases (33.5%) and 378 carotid stenosis cases (3.3%). Older age (OR=2.253, 95%CI: 2.127-2.386), urban residence (OR=2.622, 95%CI: 2.375-2.895), hypertension (OR=1.439, 95%CI: 1.195-1.732), smoking (OR=1.441, 95%CI: 1.259- 1.650), pulse pressure difference (OR=1.270, 95%CI: 1.198-1.347), fasting plasma glucose (FPG) (OR=1.109, 95%CI: 1.059-1.161) and LDL-C/HDL-C (OR=1.225, 95%CI: 1.164-1.288) were possible risk factors of CP in population at high risk for CVD. Being women (OR=0.558, 95%CI: 0.494-0.630), high BMI (OR=0.948, 95%CI: 0.904-0.994), higher levels of education (OR=0.708, 95%CI: 0.531-0.945), and higher annual household income (OR=0.773, 95%CI: 0.669-0.894) were the possible protective factors. Conclusions Over half of the population at high-risk for CVD in Jiangsu showed abnormal carotid arteries. High blood pressure, high blood glucose, high blood lipids and smoking were the main factors that could be changed.
