Objective: To investigate the self-monitoring blood pressure behavior and its influencing factors among residents in Jiangsu Province, so as to provide the basis for strengthening proactive blood pressure monitoring among residents. Methods: Permanent residents aged 35-75 years in six counties (cities, districts), Jiangsu Province, were selected using the stratified cluster sampling method in 2023. Data on basic information, disease history, and self-monitoring blood pressure behavior were collected, height and weight were measured to calculate the body mass index (BMI); and blood glucose and lipid levels were measured. Self-monitoring blood pressure behavior was defined as having measured blood pressure at least once in the past three months. Factors affecting self-monitoring blood pressure behavior were identified using a multivariable logistic regression model. Results: A total of 12 475 residents were surveyed, including 5 748 males and 6 727 females, with a male-to-female ratio of 1∶1.17. There were 3 855 residents aged 45-<55 years (30.90%) and 5 511 residents who had self-monitoring blood pressure behaviors (44.18%). Multivariable logistic regression analysis showed that the residents who were males (OR=1.167, 95%CI: 1.081-1.261), lived in rural areas (OR=1.430, 95%CI: 1.321-1.547), aged 45-75 years (45-<55 years, OR=1.384, 95%CI: 1.241-1.543; 55-<65 years, OR=1.397, 95%CI: 1.243-1.570; 65-75 years, OR=1.196, 95%CI: 1.049-1.363), had an annual household income ≥30 000 yuan (30 000-<60 000 yuan, OR=1.190, 95%CI: 1.072-1.321; 60 000-<110 000 yuan, OR=1.330, 95%CI: 1.191-1.485; ≥110 000 yuan, OR=1.746, 95%CI: 1.536-1.984), were overweight (OR=1.170, 95%CI: 1.070-1.280) or obese (OR=1.248, 95%CI: 1.120-1.391), were unaware (OR=1.221, 95%CI: 1.103-1.353) or aware (OR=3.937, 95%CI: 3.575-4.335) of having hypertension, were aware of having diabetes (OR=1.538, 95%CI: 1.354-1.749), and aware of having dyslipidemia (OR=1.265, 95%CI: 1.106-1.447) were more likely to have self-monitoring blood pressure behaviors. Conclusions Among the residents aged 35-75 years in Jiangsu Province, 44.18% had self-monitoring blood pressure behavior. Gender, place of residence, age, annual household income, BMI, hypertension, diabetes, and dyslipidemia were identified as influencing factors for self-monitoring blood pressure behavior.

ObjectiveTo investigate the effect and potential mechanism of caffeic acid （CA） on severe acute pancreatitis （SAP） induced by caerulein combined with lipopolysaccharide （LPS）， and to provide a basis for the research on novel drugs for the treatment of SAP. MethodsC57BL/6J mice， aged 6 weeks， were divided into control group， model group， CA group， and octreotide acetate （OA） group， with 6 mice in each group. The mice in the control group were given injection of normal saline， and those in the other groups were given intraperitoneal injection of caerulein combined with LPS to establish a mouse model of SAP. At 1 hour after the first injection of caerulein， the mice in the CA group and the OA group were given intraperitoneal injection of CA or subcutaneous injection of OA at an interval of 8 hours. The general status of the mice was observed after 24 hours of modeling， and serum， pancreas， lung， and colon samples were collected. HE staining was used to observe the histopathological changes of the pancreas and lungs， and the serum levels of α-amylase， lipase， tumor necrosis factor-α （TNF-α）， interleukin-6 （IL-6）， alanine aminotransferase， aspartate aminotransferase， and creatinine were measured. RT-PCR was used to measure the expression of proinflammatory factors in the pancreas and lungs； myeloperoxidase （MPO） immunohistochemistry was used to observe the degree of neutrophil infiltration； Western blot was used to measure the activation of nuclear factor-kappa B （NF-κB） and the level of citrullinated histone H3 （CitH3）， a marker for the formation of neutrophil extracellular traps （NETs）， in the pancreas and lungs， as well as the expression level of ZO-1 in colon tissue. A one-way analysis of variance was used for comparison of continuous data between multiple groups， and the Dunnett’s t-test was used for further comparison between two groups. ResultsCompared with the control group， the model group had severe injury in the pancreas and lungs and significant increases in the activity of serum α- amylase and lipase and the levels of the proinflammatory cytokines IL-6， interleukin-1β （IL-1β）， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant increases in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. Compared with the model group， the CA group had alleviated pathological injury of the pancreas and lungs and significant reductions in the activity of serum α-amylase and the levels of the proinflammatory cytokines IL-6， IL-1β， and TNF-α in serum and lung tissue （all P<0.05）， as well as significant reductions in NF-κB activation， neutrophil infiltration， and the formation of NETs in the pancreas and lungs （all P<0.05）. ConclusionCA can alleviate SAP induced by caerulein combined with LPS in mice， possibly by inhibiting neutrophil recruitment and the formation of NETs.

Objective:To understand the prevalence, blood pressure control, and influencing factors of hypertension in residents aged 35-75 years in Jiangsu Province, and provide data support and basis for hypertension prevention and treatment.Methods:A stratified cluster sampling method was adopted to conduct community population surveys in 22 districts and counties in 12 prefectures in Jiangsu from 2021 to 2022. A total of 123 531 permanent residents aged 35-75 years were included in the study. The questionnaire survey collected the information about the demographic characteristics, disease history, lifestyle, and control of hypertension of study subjects. Statistical software SPSS 23.0 was used for χ2 test and multivariate logistic regression analysis, and Joinpoint 4.9.1.0 software was used to evaluate the trend of age change. Results:The standardized prevalence of hypertension in study subjects was 46.60%, the prevalence was higher in men than in women, and in rural residents than in urban residents, and the standardized blood pressure control rate was 11.24%, and it was lower in men than in women and in rural residents than in urban residents. The hypertension prevalence and control rates showed increasing trends with age (both P<0.001). The multivariate analysis results showed that being man, older age, being rural resident, higher frequency of alcohol consumption, marital status of being separated and widowed, overweight and obese, abdominal obesity and stroke, diabetes mellitus and dyslipidaemic diseases histories, and family history of hypertension were risk factors for hypertension, and being man, being rural resident, living north area, higher frequency of alcohol consumption, and obesity were risk factors for blood pressure control. Conclusions:The prevalence of hypertension in residents aged 35-75 years in Jiangsu was high, and the rate of blood pressure control was low. It is suggested to take integrated intervention measures, especially in in rural residents and people with low levels of education to reduce the disease burden of the patients.

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 explore the relationship between marital status and mild cognitive impairment in older adults.Methods:This study is a cluster random sampling.From January to December 2020, a questionnaire survey was conducted among older adults aged 60 years and over in four cities of Hebei Province.Finally, 2690 older adults with mild cognitive impairment and normal cognitive function were enrolled.The older adults were divided into 2 groups according to their marital status: married and living with their spouses(group E1), divorced or living alone(group E2). The mini-mental state examination(MMSE)scores of older adults in the two groups were compared.Moreover, the cognitive differences of older adults between the two groups and the interaction of marital status, social activities and life events on cognitive outcomes were analyzed.Results:The married older adults with partners had better cognitive preservation( P<0.01). The more life events were more likely to cause cognitive impairment( P<0.01), and the interaction of marital status, social activities and life events had a significant impact on cognition( P<0.01). Older men who were married and lived with spouse had better cognition than older women who were married and lived with spouse( P<0.05 in Model 3). The cognition of widowed elderly women was better than those of widowed elderly men( P<0.1 in Model 1; P<0.1 in Model 2). Among elderly men, the cognition of those married and living with spouse was better than that those of widowed( P<0.01 in models 1 and 2, P<0.1 in model 3). Among elderly women, those married and living with spouse had better cognitive outcomes than those widowed( P<0.01 in Model 1, P<0.01 in Model 2). Conclusions:Marital companionship is a protective factor for the cognition of older adults, and there are gender differences in the impact of marital status on cognition in late life.

Objective:To investigate the relationship between changes in waist circumference, body weight, and blood pressure change in a high cardiovascular risk population and to provide a theoretical basis and reference for the prevention and treatment of hypertension and cardiovascular disease.Methods:A total of 12 931 patients with a high risk of cardiovascular disease participating in the follow-up survey in 2016 were selected as the study subjects, and their long-term follow-up data from 2017 to 2019 were included in the analysis. Statistical analysis was performed using a t-test, χ2 test, and generalized estimation equation (GEE). Results:Increased waist circumference, body weight, and BMI were associated with a higher risk of elevated blood pressure in people at high risk of cardiovascular disease. Waist circumference, weight, and BMI were reduced when blood pressure levels were lower. SBP and DBP increased by 0.200 (95% CI: 0.164-0.236) mmHg and 0.085 (95% CI: 0.066-0.105) mmHg for each 1 cm increase of waist circumference. SBP increased by 0.355 (95% CI: 0.289-0.421) mmHg and DBP increased by 0.182 (95% CI: 0.144-0.220) mmHg for each 1 kg increase in body weight. For each 1 kg/m 2 increase in BMI, SBP increased by 1.100 (95% CI: 1.194-1.258) mmHg, and DBP increased by 0.365 (95% CI: 0.273-0.456) mmHg. Compared with urban residents, SBP changes more with waist circumference and body weight, and DBP changes more with waist circumference in high-risk cardiovascular disease groups (all P for interaction <0.05). SBP with waist circumference and BMI and DBP with BMI was greater in participants without hypertension than in those with hypertension (all P for interaction <0.05). Conclusion:There is a positive linear correlation between the changes in waist circumference, body weight, and BMI and the changes in blood pressure in a high-risk cardiovascular disease population.

Objective:To investigate the effect of salvianolic acid on depressive behavior in depression model rats induced by chronic mild stress (CMS) and its mechanism.Methods:Fifty healthy male clean grade Sprague-Dawley(SD) rats were divided into five groups according to a random number table with 10 in each group: control group (nCMS+ Nal group), CMS+ normal saline group (CMS+ Nal group), CMS+ fluoxetine group (CMS+ Flu group), CMS+ salvia acid group (CMS+ Sal group), CMS+ fluoxetine+ Salvia acid group (CMS+ Flu+ Sal group). Except the control group, the rats in the other four groups were all received CMS modeling for 21 days. Twenty-one days after CMS modeling, rats were intraperitoneally injected with 0.9% normal saline (10 mg·kg -1·d -1), fluoxetine (20 mg·kg -1·d -1), salvia acid(40 mg·kg -1·d -1), fluoxetine(20 mg·kg -1·d -1)+ salvia acid(40 mg·kg -1·d -1)for 21 days. During the administration period, rats in the other four groups continued to receive CMS intervention for 21 days. Forced swimming test and sucrose preference test were conducted at baseline (day 0), after modeling (day 21) and after intervention (day 42) so as to evaluate depression like behavior. Then the rats were sacrificed and the hippocampus and prefrontal cortex were taken. The mRNA levels of Toll like receptor 4 (TLR4) and myeloid differentiation primary response 88 (MyD88) were detected by RT-qPCR. The cytokines including interleukin-1β(IL-1β), interleukin-2(IL-2), interferon-γ (IFN-γ) and tumor necrosis factor-α (TNF-α) were detected by Luminex technique.SPSS 21.0 was used for statistical analysis.Repeated measurement ANOVA was used for behavioral data analysis, one-way ANOVA was used for molecular index data analysis, and Spearman was used for correlation analysis. Results:The results of repeated measurement ANOVA showed that the interaction effects between group and time of body mass, sucrose preference, forced swimming immobility time were significant at baseline, after modeling and after intervention ( F=18.238, 6.921, 7.591, all P<0.05). After modeling, compared with nCMS+ Nal group, the rats in CMS+ Flu group, CMS+ Sal group, CMS+ Flu+ Sal group and CMS+ Nal group had lower body weight, lower sucrose preference rate and longer forced swimming immobility time (all P<0.05). After intervention, compared with CMS+ Nal group(body weight (350.15±41.65)g, sucrose preference(52.95±11.13)%, static time(91.40±15.22)s), the body weight((378.21±30.78)g, (385.12±43.19)g, (391.41±31.21)g, (402.33±18.67)g, all P<0.05) and sucrose preference((69.30±15.56)%, (68.12±10.99)%, (71.18±9.51)%, (75.47±11.55)%, all P<0.05) of CMS+ Flu group, CMS+ Sal group, CMS+ Flu+ Sal group and nCMS+ Nal group were all increased, while the forced swimming immobility time ((68.81±21.74)s, (66.10±25.51)s, (63.53±22.32)s, (71.21±21.41)s, all P<0.05) were shorter (all P<0.05). After intervention, among the body weight, sucrose preference and the immobility time of CMS+ Flu group、CMS+ Sal group and CMS+ Flu+ Sal group, there were no differences between each two groups(all P>0.05). After intervention, the levels of TLR4 mRNA and MyD88 mRNA in prefrontal cortex and hippocampus of CMS+ Flu group, CMS+ Sal group, CMS+ Flu+ Sal group and nCMS+ Nal group were all lower than those in CMS+ Nal group (all P<0.05). In prefrontal cortex, the levels of TLR4 mRNA (0.715±0.358) and MyD88 mRNA (0.739±0.233) in CMS+ Flu+ Sal group were lower than those in CMS+ Sal group (1.943±0.606, 1.815±0.897) (both P<0.05). The level of TLR4 mRNA in prefrontal cortex and hippocampus of rats were positively correlated with the level of MyD88 mRNA and TNF-α level and forced swimming immobility time and negatively correlated with sucrose preference rate (prefrontal cortex r=0.915, 0.041, 0.027, -0.178, all P<0.05; hippocampus r=0.810, 0.070, 0.011, -0.153, all P<0.05). Conclusion:The antidepressant effect of salvianolic acid is presumedly achieved by inhibiting the immunoinflammatory response mediated by the TLR4/Myd88 signaling pathway in CMS rats.

OBJECTIVE：To investigate the e ffects of Zhuangtongyin water extract （ZTYWE）on hemorheology and blood lipid level of myocardial ischemia-reperfusion model rats ，and preliminarily explore its molecular biology foundation of reducing arrhythmia after myocardial ischemia-reperfusion. METHODS ：Totally 75 SD rats were divided into control group ，model group and ZTYWE low-dose ，middle-dose and high-dose groups. Myocardial ischemia-reperfusion model was established by ligating the left ventricle cyclotron endings for 30 min then reperfusing for 60 min. Since the first day after surgery ，control group and model group were intraperitoneally administrated with same volume normal saline ；ZTYWE low-dose ，middle-dose and high-dose groups were intraperitoneally administrated with medicine solution （6.8，13.6，27.2 g/kg），once a day ，for continuous 28 d. At the 7th， 14th，21st，28th day after surgery ，the incidence rate of arrhythmia of rats were detected. The hemorheology indicators and serum contents of TC ，TG，LDL-C，HDL-C were determined after the last administration. The morphology of myocardial tissue was observed by HE staining. The protein expressions of apoptosis-related factor FAS and FAS-L were detected by Western blotting assay. RESULTS ：Compared with control group ，the incidence rates of arrhythmia of rats in model group were significantly increased；the whole blood contrast viscosity ，hematocrit（HCT），in vitro forming length and quality of thrombosis ，platelet aggregation rate ，erythrocyte filtration index （IF），as well as the serum contents of TC ，TG and LDL-C were significantly increased；in vivo thrombus formation time as well as the serum content of HDL-C were significantly decreased ；the protein expression of FAS and FAS-L were significantly increased （P＜0.05 or P＜0.01）；obvious pathological changes were observed in myocardial tissue. Compared with model group ， the incidence rates of arrhythmia of rats in ZTYWE groups were in obvious reducing trend ； except for the HCT in 163.com low-dose ZTYWE group without significance ， the blood contrast viscosity ，HCT，in vitro forming length and quality of thrombosis ，platelet aggregation rate ，IF as well as the serum contents of TC ，TG and LDL-C were significantly decreased ；in vivo thrombus formation time as well as the serum contents of HDL-C were significantly increased ；the protein expressions of FAS and FAS-L were significantly decreased （P＜0.05 or P＜ 0.01）；the pathological changes of myocardial tissue were improved. CONCLUSIONS ：Through the promoting blood circulation and removing blood stasis effect ，Zhuangtongyin decoction can improve indexes of hemorheology index of ischemia-reperfusion model rats ，reduce the contents of TC ，TG and LDL-C ，enhace the contents of HDL-C ，down-regulate the protein expression of FAS and FAS-L ，so as to inhibit myocardial cells apoptosis and reduce arrhythmia.

Objective To investigate the effect of prenatal stress (PS) at different pregnant time on emotion and cognition of adult offspring rats.Methods Twelve healthy female Sprague Dawley (SD) rats were randomly divided into control group(CON,n=4),the early pregnancy group(PS1,the 1～ 7 days of pregnancy,n=4) and the late pregnancy group(PS3,the 15 ～ 21 days of pregnancy,n=4).The pregnant rats were exposed to single-prolonged stress(SPS) on gestational day 7 or 15 respectively,except control group.The offspring were measured every weekend from 1-7 week after birth.At the eighth weekend,the sucrose intake (anhedonia) and Morris water maze (MWM) were performed to assess depression-like behavior and spatial learning and memory.Results The body weight of the first to seventh weeks after birth showed that there was a statistically significant difference among the three groups (F=28.207,P＜0.01),and there was a significant difference in time effect (F=1 041.546,P＜0.01).The body weight of two PS groups was significantly lower than those of control group(P＜0.05).The body weight of PS3 was lower than that of PS1 significantly(P＜0.05).Sucrose preference:PS3((27.70± 19.31) ％) were reductive on sucrose consumption than CON significantly((66.93±19.67) ％)(P＜0.05)while PS1 ((89.80±6.79) ％) increased in sucrose consumption compared with the CON significantly(P＜0.05).MWM:in training stage the difference of average avoid latency was existed in the three groups of the first 5 days(F=11.121,P＜0.01).Similarly,there was a significant difference in measure time(F=91.327,P＜0.01),the escape latency of the PS3 was decreased,while PS1 was significantly increased compared with CON;in testing stage,PS3 ((54.50±4.64) s,(53.21±4.45)) showed a significant increase in the duration in target site and numbers of times across the target site compared with CON((32.24±.4.17) s,(31.68±4.00)) (P＜0.05).Conclusion The acceptance of stress in the late pregnancy may lead to depression like behavior in the adult offspring and also enhance the learning and memory ability.And acceptance of stress in early pregnancy can cause impairment of learning and memory ability in adult offspring rats.

Objective To compare the risk factors of breast cancer in Ningxia Hui and Han women,and to provide evidence for the prevention and control of breast cancer.Methods The female patients of breast cancer treated at the Affiliated Hospital of Ningxia Medical University between May 2013 and July 2014 were chosen for case study,while other patients treated at the same hospital and during the same period who did not have breast cancer were selected as a control. An epidemiological survey was conducted using the same questionnaire among the two groups.The survey involved general demographic information,menstrual history,reproductive history,life habit and family history of cancer.Risk factors of breast cancer in Hui and Han nationalities were analyzed by logistic regression analysis.Results Logistic regression analysis showed that the abortion number(OR =2.631,P =0.028)was a risk factor for the occurrence of breast cancer in women of the Hui nationality,while physical exercise (OR =0.177,P =0.040)was a protective factor.Tumor suffered by immediate family members (OR =4.249,P =0.014),abortion number (OR =1.602,P =0.001 ),the age of the first childbirth (OR =1.253,P =0.001 )and the age of first marriage(OR =1.223,P =0.001 )were the major risk factors while physical exercise (OR =0.422,P =0.001 )was a protective factor against breast cancer in Han nationality. Conclusion The risk factors of breast cancer in the women of Hui and Han nationalities are consistent in terms of the total number of abortions and physical exercise.Compared with the Hui people,the age of first marriage,the age of first child birth,and tumor suffered by immediate family members also play a role in the occurrence of breast cancer in the Han na-tionality.
