Objective: To investigate the characteristics and trend of stroke incidence in Jining City, Shangdong Province from 2015 to 2022, so as to provide the reference for formulating prevention and control strategies of stroke. Methods: Data of stroke incidence in Jining City from 2015 to 2022 were collected from Shandong Provincial Chronic Disease Surveillance Information Management System. The crude incidence was estimated, standardized using the data of the sixth national population census in 2010, and analyzed by age, gender and subtype. The trend in incidence of stroke was analyzed using annual percent change (APC). Results: A total of 316 267 cases of stroke were reported in Jining City from 2015 to 2022, with a crude incidence of 474.17/105 and a standardized incidence of 371.43/105. The incidence of stroke peaked from March to May (90 409 cases, 28.59%). There were 278 901 cases of ischemic stroke (88.19%) and 37 366 cases of hemorrhagic stroke (11.81%). The crude incidence of stroke was higher in males than in females (525.45/105 vs. 420.16/105, P<0.05). The crude incidence of stroke increased with age (P<0.05), reaching a peak in the age group of 80 years and above (2 764.92/105). From 2015 to 2022, the crude incidence of stroke in the overall population, males, females, the age groups of 0-<30 years and 40-<50 years showed increasing trends (APC=6.142%, 6.992%, 5.054%, 3.693% and 6.587%, all P<0.05); the crude incidence of ischemic stroke in the overall population, males and females showed increasing trends (APC=7.489%, 6.593% and 5.456%, all P<0.05), while the crude incidence rates of hemorrhagic stroke did not show significant trends (APC=3.455%, 2.804% and 1.919%, all P>0.05). Conclusions The crude incidence of stroke increased in Jining City from 2015 to 2022, with ischemic stroke as the predominant subtype. March to May was the peak period for disease onset, and young and middle-aged men should be focused on.

Objective: To examine the mediating effects of mindfulness level on resilience and symptoms of anxiety and depression among healthcare workers, so as to provide the reference for developing effective psychological intervention. Methods: The clinical doctors, nurses and public health professionals were selected using the stratified random cluster sampling method from hospitals, disease prevention and control centers, and health departments in five cities in Shandong Province, including Qingdao, Jinan, Rizhao, Jining and Liaocheng in January 2023. Basic information, mindfulness level, resilience and symptoms of anxiety and depression among healthcare workers were collected using general demographic questionnaires, the 5-item Mindful Attention Awareness Scale, 10-item Connor-Davidson Resilience Scale, Generalized Anxiety Disorder Scale and Patient Health Questionnaire, respectively. The Process program was used to analyze the mediating effects of mindfulness level on resilience and symptoms of anxiety and depression. Results: A total of 1 836 healthcare workers were investigated, including 472 males (25.71%) and 1 364 females (74.29%), and the median age was 39 (interquartile range, 12) years. There were 629 clinical doctors (34.26%), 963 nurses (52.45%) and 244 public health professionals (13.29%). The median scores of mindfulness level and resilience were 22 (interquartile range, 7) and 20 (interquartile range, 4) points, respectively. The detection rates of anxiety and depression symptoms were 49.78% and 72.28%, respectively. The mediation analysis showed that mindfulness level exerted a partial mediating effect between resilience and anxiety symptoms (β=-0.510, P<0.001), with a direct effect value of -0.130 and a mediating effect value of -0.046, and the mediating effect accounted for 26.14% of the total effect; mindfulness level also exerted a partial mediating effect between resilience and depression symptoms (β=-0.575, P<0.001), with a direct effect value of -0.120 and a mediating effect value of -0.052, and the mediating effect accounted for 30.23% of the total effect. Conclusion Mindfulness level plays a mediating effect between resilience and symptoms of anxiety and depression among healthcare workers.

Objective:To evaluate the efficacy and safety of hypomethylating agents (HMA) in patients with myelodysplastic syndromes (MDS) .Methods:A total of 409 MDS patients from 45 hospitals in Zhejiang province who received at least four consecutive cycles of HMA monotherapy as initial therapy were enrolled to evaluate the efficacy and safety of HMA. Mann-Whitney U or Chi-square tests were used to compare the differences in the clinical data. Logistic regression and Cox regression were used to analyze the factors affecting efficacy and survival. Kaplan-Meier was used for survival analysis. Results:Patients received HMA treatment for a median of 6 cycles (range, 4-25 cycles) . The complete remission (CR) rate was 33.98% and the overall response rate (ORR) was 77.02%. Multivariate analysis revealed that complex karyotype ( P=0.02, OR=0.39, 95% CI 0.18-0.84) was an independent favorable factor for CR rate. TP53 mutation ( P=0.02, OR=0.22, 95% CI 0.06-0.77) was a predictive factor for a higher ORR. The median OS for the HMA-treated patients was 25.67 (95% CI 21.14-30.19) months. HMA response ( P=0.036, HR=0.47, 95% CI 0.23-0.95) was an independent favorable prognostic factor, whereas complex karyotype ( P=0.024, HR=2.14, 95% CI 1.10-4.15) , leukemia transformation ( P<0.001, HR=2.839, 95% CI 1.64-4.92) , and TP53 mutation ( P=0.012, HR=2.19, 95% CI 1.19-4.07) were independent adverse prognostic factors. There was no significant difference in efficacy and survival between the reduced and standard doses of HMA. The CR rate and ORR of MDS patients treated with decitabine and azacitidine were not significantly different. The median OS of patients treated with decitabine was longer compared with that of patients treated with azacitidine (29.53 months vs 20.17 months, P=0.007) . The incidence of bone marrow suppression and pneumonia in the decitabine group was higher compared with that in the azacitidine group. Conclusion:Continuous and regular use of appropriate doses of hypomethylating agents may benefit MDS patients to the greatest extent if it is tolerated.

Objective:To survey the awareness status and its influencing factors among parents of preschool children.Methods:Data was collected from the National Nutrition and Health Systematic Survey for 0-18 Year Children in China. A total of 2 625 children aged 3-5 years and their parents living in northern and southern regions of China were randomly selected by multi-stage stratified cluster sampling. The physical measurements were performed for the children, including height and weight; and the body mass index (BMI) and age-for-BMI Z-score (BAZ) were calculated. The questionnaire survey was conducted for the parents, including the demographic characteristics of parents and their children, the perception of their child′s nutritional status (overweight/obesity, normal, wasting) etc. According to WHO standards, the nutritional status of the children was classified as wasting, normal and overweight/obesity. The awareness of parents on their children′s nutritional status was classified as underestimated, correct, overestimated and unclear. Parents′ inability to correctly judge children′s nutritional status was defined as cognitive bias, including underestimation bias and overestimation bias. Multivariate logistic regression model was used to analyze the influencing factors of parents′ underestimation or overestimation of children′s nutritional status.Results:Among 2 625 enrolled preschool children, there were 1 312 boys (50.0%) and 1 313 girls (50.0%); and 648 (24.7%), 944 (36.0%) and 1 033 (39.3%) children aged 3, 4 and 5 years, respectively. One parent (mother, farther or others) of each child was selected for survey, and most of them were mothers (1 998(76.1%)). The prevalence rate of overweight/obesity and wasting was 10.3% (270/2 625) and 1.4% (38/2 625), respectively; and 2 317 children (88.3%) were normal. Among all parents surveyed, 1 766 (67.3%) were correct about their children′s nutritional status (correct group), 612 (23.3%) underestimated their children′s nutritional status (underestimated group), 213 (8.1%) overestimated their children′s nutritional status (overestimated group) and 34 (1.3%) were not aware of their children′s nutritional status (unclear group). The multivariate logistic regression analysis showed that girls ( OR=0.817, 95% CI: 0.678-0.984), living in rural areas ( OR=0.801, 95% CI: 0.662-0.969), large birth weight of child ( OR=0.639, 95% CI: 0.420-0.970) were protective factors for parents underestimating children′s nutritional status. Living in the northern region ( OR=1.698, 95% CI: 1.260-2.290), large birth weight of children ( OR=1.826, 95% CI: 1.149-2.902), father with overweight/obesity ( OR=1.467, 95% CI: 1.089-1.977) and maternal overweight/obesity ( OR=1.778, 95% CI: 1.308-2.417) were the risk factors for parents to overestimate the nutritional status of children. Conclusions:The survey shows that parents of preschool children have a relatively high cognitive bias on the nutritional status of their children. Parents of girls, living in rural areas or having child with large birth weight are less likely to underestimate the nutritional status of children; parents living in northern regions, having a child with large birth weight, or with overweight/obese are likely to overestimate the nutritional status of children.

Objective: The consistency of 24-hour oropharyngeal Dx-pH monitoring and proton pump inhibitor(PPI) test in the diagnosis of laryngopharyngeal reflux disease (LPRD) was investigated. Methods: Sixty patients with laryngopharyngeal reflux (LPR) related symptoms who had never received PPI treatment were assessed by reflux symptom index (RSI) and reflux finding score (RFS) between October 2017 and October 2018, including 28 males and 38 females, aged from 16 to 72 years, with a medium age of 38 years. Prior to treatment, all patients were evaluated with 24 hours oropharyngeal Dx-pH monitoring(Restech). After empiric therapy with PPI twice-daily for 8 weeks, the efficacy was evaluated according to posttreatment RSI score.The data was analysed with Kruskal-Wallis test, Student Newman Keuls test and consistency check. Results: (1)Among all 60 patients,13 patients (21.7%) had pathologic Ryan score and all resulted responsive to PPI;27 patients (45.0%) with a negative Ryan score were unresponsive to PPI; 20 patients (33.3%) despite a negative Ryan score resulted responsive to PPI therapy. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of Ryan score were 39.4%, 100%, 100% and 57.4% respectively. The Kappa value was 0.369 (P<0.01). (2)Among 34 patients (56.7%) with positive Dx-pH results (24-hour oropharyngeal acid reflux events≥ 3 times), 29 patients were positive and 5 patients were negative in PPI test. Among 26 patients with negative Dx-pH results (24-hour oropharyngeal acid reflux events<3 times), 4 patients were positive and 22 patients were negative in PPI test. Considering responsiveness to PPI therapy as the gold standard for the diagnosis of LPRD, the sensitivity, specificity, positive predictive value and negative predictive value of 24-hour oropharyngeal acid reflux events were 87.9%, 81.5%, 85.3% and 84.6% respectively. The Kappa value was 0.696(P<0.01). Conclusions There is a positive correlation between 24-hour oropharyngeal Dx-pH monitoring positive results (24-hour oropharyngeal acid reflux events≥3 times) and PPI test in the diagnosis of LPRD. The 24-hour oropharyngeal Dx-pH monitoring can be a promising tool for the diagnosis of suspected LPRD patients, and more sensitive and accurate Dx-pH diagnostic index will be required in the clinic.

Objective: To explore the association between dietary pattern which benefit for normal kidney function and the risk of cognitive decline or impairment in the elderly. Methods: In 2015, subjects aged 60 and over from four counties in the Nutrition and Chronic Disease Family Cohort project, were followed up in 2017. Cognitive function was repeatedly assessed, using the Mini Mental State Evaluation (MMSE) scale. Dietary pattern that benefit for normal kidney function was extracted, using the reduced rank regression method and followed by logistic regression models to explore the associations between scores that showing the kidney function on dietary patterns and the risk of cognitive deterioration and impairment in two years among those who were with normal cognition in 2015. Results: Dietary pattern that benefit for normal kidney function, was characterized by high consumption of cereal, vegetables, legume and fruits but with less meat and soy products. Comparing with the group with lowest score quartile on this dietary pattern, the risk of cognitive deterioration in the highest quartile group was significantly low (P<0.01) in two years, with an odds ratio as 0.57 (95%CI: 0.37-0.85). Linear trend was also obviously visible (P=0.007) in this group. The ones at the highest quartile group among the normal cognition ones in 2015, the risk of cognitive impairment also significantly reduced (P<0.05) in two years time, with an odds ratio as 0.52 (95%CI: 0.29-0.93). Also, linear trend could obviously be seen (P=0.01). Conclusion Dietary pattern that benefit for normal kidney function was both inversely associated with cognitive deterioration and impairment, in two years.

Objective: To assess the relationship between body mass index (BMI) and mortality in adults of Shanxi, China. Methods: Baseline data were from the '2002 China Nutrition and Health Survey’ in Shanxi province. All the death-related investigation and follow-up visits were carried out from December 2015 to March 2016. The follow-up program covered 5 360 people from all the 7 007 participants aged 18 years and over that having complete core information, with a rate as 76.5%. Participants of this study were divided into eight groups, according to the appearance of BMI. Taking the group with the lowest mortality density as the reference group, Cox regression model was used to estimate the hazard ratio (HR) and 95% confidence interval (CI) of deaths by the whole population, gender and age groups (≥60 years, <60 years). Results were then adjusted by age, gender, smoking, alcohol use and education level from the baseline survey. Sensitivity analysis was also conducted. Results: Results from the study showed that among the total number of 67 129 person- years from the average period of 12.5 years, there were 615 deaths occurred, with the mortality density as 916 per 100 000 person-years. Taking the BMI range of 26.0-27.9 kg/m² as the reference, the aHRs of death increased to 1.90 (95%CI: 1.26-2.86), 1.68 (95%CI: 1.15-2.45), 1.49 (95%CI: 1.08-2.06) and 1.72 (95%CI: 1.07-2.76) after the multivariate adjustment, in these four groups (BMI<18.5, 18.5-19.9, 22.0-23.9 and ≥30.0 kg/m²), respectively. Low body weight (BMI<18.5 kg/m²) was associated with higher risks of death in the elderly of ≥60 years, with the aHR of death as 1.94 (95%CI: 1.20-3.15). Conclusions When BMI appeared as ≤19.9 kg/m², 22.0-23.9 kg/m² and ≥30.0 kg/m², the risks of death would increase. In addition to programs that focusing on obesity, special attention should be paid to the high risk of mortality which was caused by low-weight and malnutrition in the elderly.

Objective: To analyze the longitudinal change of serum total cholesterol concentration in 733 rural residents in Shanxi province. Methods: Based on the residents of five rural areas in Shanxi province who participated in China nutrition and health survey in 2002, a follow-up survey was conducted in 2015. Fasting venous blood of the participants was collected and serum TC concentration was tested by cholesterol oxidase method. Results: Of 733 participants, 332 were male and 401 were female. In 2002 baseline survey, the age of the participants was (42.6±9.5) years old, 76.2% of male and 83.8% of female had junior middle school education or below. Proportion of smoking were 65.7% and 1.2%, drinking were 26.8% and 4.0%, obesity were 6.3% and 12.0%, and central obesity were 27.1% and 31.9%, respectively in male and female. The follow-up age of participants in 2015 was (55.8±9.5) years old, proportion of smoking changed to 48.2% and 1.5%, drinking were 49.7% and 3.0%, obesity increased to 11.8% and 18.2% and central obesity increased to 41.6% and 53.6%, respectively in male and female. The overall serum TC level increased from (3.82±0.89) mmol/L to (4.72±0.97) mmol/L with an average increase of 27.2%, which increased from (3.84±0.94) mmol/L to (4.54±0.93) mmol/L in male with an average increase of 22.7%, and increased from (3.81±0.84) mmol/L to (4.86±0.98) mmol/L in female with an average increase of 30.9%. The serum TC levels in 18-, 30-, 40-, and 50-59 years old group increased from (3.42±0.83), (3.72±0.77), (3.90±0.83) and (4.00±1.03) mmol/L to (4.38±1.01), (4.79±0.92), (4.73±0.99) and (4.76±0.96) mmol/L, with average increase range of 31.4%, 32.1%, 25.2% and 22.6%, respectively. The mean serum TC levels between two years all had statistically significant difference among groups of gender, age, education, marital status, family history of cardiovascular disease, smoking, drinking, BMI and waist circumference after paired t-test and ANOVA analysis (P<0.01). Conclusion The longitudinal serum TC level of rural residents in Shanxi province increased rapidly.

Objective: To analyze the blood pressure changes of adults aged 18-59 years in rural area of Shanxi province based on a cohort study, and provide reference for the study of the blood pressure level of rural residents and hypertension prevention and control in rural areas in China. Methods: Data were obtained from Shanxi Nutrition and Chronic Disease Family Cohort from 2002 to 2015. Subjects aged <18 years or ≥60 years and individuals with hypertension at baseline survey in 2002, and those who had taken antihypertensive drugs for nearly two weeks during the follow-up survey in 2015 were excluded from the study. A total of 1 629 subjects aged 18-59 years were included in the analyses of the blood pressure level and its change from the baseline survey in 2002 to follow-up survey in 2015. Results: The systolic blood pressure (SBP) of the subjects increased from (122.7±10.4) mmHg in 2002 to (132.8±17.6) mmHg in 2015 and the diastolic pressure (DBP) increased from (72.7±6.9) mmHg in 2002 to (78.8±10.3) mmHg in 2015. The SBP in men and women increased with growth rates of 6.7% and 9.5%. While DBP in men and women increased with growth rates of 9.3% and 7.8%. The SBP levels of those aged 18-, 30-, 40- and 50-59 years increased with growth rates of 5.0%, 6.7%, 9.4% and 11.8%. While the DBP of these age groups increased with growth rates of 12.2%, 8.2%, 8.2% and 6.5%. Conclusions The blood pressure of adults aged 18-59 years old in rural area of Shanxi showed a substantially increasing trend. The mean increase level of SBP in women was higher than that in men, and increased with age. While the mean increase level of DBP in men is higher than that in women, and decreased with age.

Objective:To assess the impact of zero makeup policy for drug and medical supplies on hospitals. Methods:Descrip-tive statistics and comparative analysis were used to analyze the related indicators, profit and loss calculation and the cost of patients from April 2014 to March 2017.Results:After the policy was implemented, the number of outpatients and the number of outpatients choosing general doctors decreased. The average length of hospitalization was 8.88 days, and the proportion of drug consumption was 34.10%. The number of outpatients choosing medical experts, the number of inpatients and the proportion of surgical treatment in-creased. Although the policy benefited patients,the average medical expenditure still increased. There was policy loss in the hospital. Conclusion:The reform promotes the implementation of hierarchical medical system, optimizes the hospital income structure and re-duces drug proportion significantly,which achieves the original intentions of the policy to some extent.
