ObjectiveTo investigate the possible mechanism of Shenqi Jianxin Formula （参芪健心方） in the treatment of chronic heart failure （CHF） from the perspective of pyroptosis. MethodsFifty-two rats were randomly divided into sham operation group （n=8） and modeling group （n=44）. In the modeling group， the anterior descending branch of the left coronary artery was ligated to construct CHF rat model. Forty successfully-modelled rats were randomly divided into model group， Entresto group， Shenqi Jianxin Formula group， MCC950 group and the combination group （Shenqi Jianxin Formula plus MCC950）， with 8 rats in each group. In Shenqi Jianxin Formula group， 7.4 g/（kg·d） of Shenqi Jianxin Formula was given by gavage， while in Entresto group， 68 mg/（kg·d） of Entresto suspension was given by gavage； in MCC950 group， MCC950 was injected intraperitoneally with 10 mg/kg once every other day， and in the combination group， 7.4 g/（kg·d） of Shenqi Jianxin Formula was given by gavage， and MCC950 was injected intraperitoneally with 10 mg/kg once every other day； 10 ml/（kg·d） of saline was given by gavage in the sham operation group and the model group. After 3 weeks of continuous intervention， serum brain B-type natriuretic peptide （BNP）， creatine kinase isoenzyme MB （CK-MB）， interleukin 1β （IL-1β）， and interleukin 18 （IL-18） levels were detected by ELISA； HE staining and MASSON staining were used to observe pathological changes in rat myocardium. Except for the Entresto group， western blot technique was used to detect the expression of NOD-like receptor protein 3 （NLRP3）， caspase-1， and apoptosis-associated speck-like protein possessing a caspase-recruiting domain （ASC）； RT-PCR was used to detect the expression of NLRP3 and caspase-1 mRNA. ResultsCompared with the sham operation group， HE staining of rats in the model group showed obvious myocardial injury， while MASSON staining showed increased area of collagen fibrosis， and serum BNP， CK-MB， IL-1β， IL-18， myocardial tissue NLRP3， caspase-1， ASC protein expression and NLRP3， caspase-1 mRNA expression were all elevated （P＜0.05）. Compared with those in the model group， cardiomyocyte injury of rats and collagen fibrosis area were reduced， and serum BNP， CK-MB， IL-1β， and IL-18 contents were all reduced in Shenqi Jianxin Formula group， Entresto group， MCC950 group， and the combination group； except for Entresto group， myocardial tissue NLRP3， caspase-1， ASC protein expression and NLRP3， caspase-1 mRNA expression were reduced in the remaining three medication group （P＜0.05）. Compared with Shenqi Jianxin Formula group， the MCC950 group and the combination group showed decreased serum IL-1β and IL-18 content， collagen fibrosis area， myocardial tissue NLPR3， caspase-1 protein expression， and caspase-1 mRNA expression， and decreased ASC and NLRP3 mRNA expression was shown in the combination group （P＜0.05）. Compared with MCC950 group， collagen fibrosis area was reduced， and serum IL-18 content， NLRP3， caspase-1 mRNA expression were reduced in the combination group （P＜0.05）. ConclusionShenqi Jianxin Formula can effectively improve the myocardial injury and heart failure in rats with CHF， and its mechanism may be related to the inhibition of cardiomyocyte pyroptosis through NLPR3/Caspase-1 pathway to reduce the level of intramyocardial inflammation. The combined use of MCC950 with Shenqi Jianxin Formula could more effectively inhibite myocardial pyroptosis， with better therapeutic result than single use of each part.

Objective: To investigate the willingness to accept preventive treatments and its related factors among college freshmen with latent tuberculosis infection (LTBI), so as to provide the evidence for preventive treatment intervention measures for students with LTBI. Methods: Cluster sampling method was used to select 368 LTBI freshmen from 8 colleges and universities in Changzhou in September 2023, who conducted a questionnaire survey on the willingness to receive preventive treatment. General demographic data were collected and relevant data were collected using tuberculosis knowledge scale, General Anxiety Disorder-7 (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Adaptation, Partnership, Growth, Affection and Resolve (APGAR), and a self developed Stigma Scale. A binary Logistic regression model was constructed with the willingness to accept preventive treatment as the dependent variable to analyze the willingness to accept preventive treatment and the influencing factors. Results: A total of 253 LTBI college freshmen were willing to take preventive treatment, the acceptance rate was 68.75%. The rate of willingness to accept preventive treatment for LTBI was higher among students whose fathers had an education level of high school, compared to those whose fathers had an education level of junior high school or below ( OR =2.16, P <0.05). LTBI students whose per capita family income was >5 000-10 000 yuan and >10 000 yuan were more willing to accept LTBI preventive treatment than those whose per capita family income was <3 000 yuan ( OR =2.72, 4.46, P <0.05). LTBI students who engaged in physical exercise for more than 2 hours per week were more willing to accept than those who exercised less than 0.5 hours per week ( OR =1.91, P <0.05). LTBI students with high levels of tuberculosis knowledge and stigma were more likely to receive preventive treatment ( OR =1.18, 1.11, P < 0.05). LTBI students with high PHQ-9 ( OR =0.85) and GAD-7 ( OR =0.92) scores were more likely to refuse preventive treatment ( P <0.05). Conclusion The present study revealed a moderate level of willingness of LTBI students to preventive treatment in Changzhou City, and the acceptance is affected by family factors, healthy lifestyles, tuberculosis knowledge and psychological status.

Objective:To analyze the value of 68Ga-fibroblast activation protein inhibitor (FAPI)-04 PET/CT in the detection of myocardial injury in patients treated with anti-tumor therapy. Methods:A retrospective study was conducted on 164 patients who underwent 68Ga-FAPI-04 PET/CT to evaluate the efficacy of anti-tumor therapy in Renji Hospital, School of Medicine, Shanghai Jiao Tong University between August 2021 and March 2024. The patients were divided into 68Ga-FAPI-04-positive group ( n=63, 36 males, 27 females, age (66.7±9.6) years) and 68Ga-FAPI-04-negative group ( n=101, 42 males, 59 females, age (55.2±14.1) years) based on the uptake of left ventricular myocardium (LVM). Moreover, FAPI-04 uptake was analyzed based on different types and locations, and the corresponding SUV max differences were analyzed by Kruskal-Wallis rank sum test. The differences of SUV max between 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were analyzed by Mann-Whitney U test. The clinical factors such as gender, age, body mass index (BMI), previous history of coronary heart disease, left ventricular ejection fraction (LVEF), smoking history, hypertension, diabetes, cancer types and immune checkpoint inhibitors (ICIs) treatment were collected, and their predictive values for LVM 68Ga-FAPI-04 uptake were investigated by the binary logistic regression analysis. Results:Fifty patients of the 68Ga-FAPI-04-positive group (79.4%, 50/63) showed focal uptake of LVM, 7 patients (11.1%, 7/63) showed multifocal myocardial uptake, and 6 patients (9.5%, 6/63) showed diffuse myocardial uptake. A total of 127 uptake lesions were found, and most of them were located in the septum (37.8%, 48/127). The SUV max of LVM in 68Ga-FAPI-04-positive group and 68Ga-FAPI-04-negative group were 4.00(3.10, 5.40) and 1.31(1.20, 1.40) respectively ( z=-10.82, P<0.001). Differences of the SUV max among focal uptake group, multifocal myocardial uptake group, and diffuse myocardial uptake group were not significantly different (4.00(3.00, 5.10) vs 7.60(3.60, 9.30) vs 3.95(3.05, 5.05); H=3.81, P=0.149). There is no statistically significant difference either in FAPI uptake among different sites of LVM ( H=1.51, P=0.825). Age, previous history of coronary heart disease, BMI, LVEF and ICIs treatment were independent predictive factors for positive 68Ga-FAPI-04 uptake in the LVM (odds ratio ( OR) values: 0.87-10.43, all P<0.05). Conclusion:68Ga-FAPI-04 PET/CT is a potential new imaging method for the visualization of myocardial injury in patients with anti-tumor therapy.

In order to investigate developmental coordination disorder (DCD) of kindergarten children in Zhejiang province, 200 ordinary kindergartens were randomly selected by stratified random sampling in 11 prefecture-level cities of Zhejiang Province, and 38 900 children from 1 000 classes in each grade were then randomly selected into the study from June 2019 to December 2019. The Little DCD Questionnaire and a self-designed questionnaire were used to screen the DCD of those children. There were 36 807 valid questionnaires, and 6.50% (2 391/36 807) of them were positive results. The results showed that boy, age ≤5 years, overweight or obesity, left handedness, comorbidity with motor or developmental disorders and premature infants were risk factors of DCD in children. As for parents and families, maternal gestational age<20 years, maternal overweight or obesity before pregnancy, low-middle level education of parents, direct family and low income of family were also associated with DCD in children. Therefore, it is necessary to conduct early prevention and intervention strategies targeting on identified risk factors among relevant population.

Objective:To analyze the epidemiological and etiological characteristics of dengue fever in Hangzhou in 2018.Methods:RT-PCR was used to detect the nucleic acids and analyze the serotypes of dengue viruses (DENV) in serum samples collected from dengue fever cases. Phylogenetic trees based on the E gene sequences of DENV isolated from the serum samples were then constructed and analyzed. Epidemiological characteristics of these dengue fever cases were analyzed. Results:A total of 80 cases of dengue fever were detected in Hangzhou in 2018 with 55 imported cases and 25 indigenous cases (24 caused by DENV-1 and one by DENV-3). These indigenous cases mainly occurred during late July to early October with people above 50 years old accounting for 68%. Phylogenetic analysis showed that DENV-1 strains isolated from the indigenous cases in Yuhang, Jianggan-Shangcheng and Qiantang districts all belonged to genotype Ⅰ, and were respectively closely related to the strains from Indonesia in 2015, Myanmar in 2017, Ningbo in 2018 and Hangzhou imported cases from Thailand in 2018. The indigenous DENV-3 strain belonged to genotype Ⅲ, and shared 99.5% homology with the Singapore strain in 2013.Conclusions:Imported cases accounted for a large fraction of the dengue fever cases in Hangzhou, which brought a high risk to indigenous outbreak. Due to multiple imported cases, the current epidemic presented a characteristic of multiple small-scale outbreaks.

Objective:To construct a simple, precise and personalized comprehensive nomogram for prediction the risk of multidrug-resistant tuberculosis (MDR-TB) and to evaluate its prediction value among individuals with previous tuberculosis history (PTBH).Methods:A matched case-control study (1∶2 ratios) was performed in 1 881 patients with PTBH treated in 12 designated tuberculosis hospitals in Hangzhou City between January 1, 2005 and December 31, 2019, and there were 1 719 patients in training set, and 162 in validation set. A multivariable Cox regression analysis was used to evaluate independent predictors for the incident of MDR-TB in individuals with PTBH. A comprehensive nomogram was developed based on the multivariable Cox model. The accuracy of the prediction was assessed using concordance index (C-index), calibration curve and area under the receiver operator characteristic (ROC) curve.Results:The nomogram constructed based on the multivariable Cox regression model incorporated 10 independent predictors of the risk of MDR-TB. A history of direct contact (grade 1, 0-100.0 points) ranked on the top of all risk factors, followed by duration of positive sputum culture (grade 2, 0-84.5 points), unfavorable treatment outcome (grade 3, 0-52.0 points), human immunodeficiency virus infection (grade 4, 0-48.5 points), retreated tuberculosis history (grade 5, 0-40.0 points), non-standardized treatment regimens of retreated tuberculosis (grade 6, 0-32.5 points), duration of pulmonary cavities (grade 7, 0-31.0 points), passive mode of tuberculosis case finding (grade 8, 0-25.0 points), age<60 years (grade 9, 0-17.5 points), and standard frequencies of chest X-ray examination (grade 10, 0-14.0 points). The C-indexes of this nomogram for the training and validation sets were 0.833 (95% confidence interval ( CI) 0.807-0.859) and 0.871 (95% CI 0.773-0.969), respectively, indicating that the nomogram had good fitting effect. The calibration curves for the risk of incident MDR-TB showed an optimal agreement between nomogram prediction and actual observation in the training and validation sets, respectively.The areas under ROC curve of the 1-year, 5-year, and 10-year MDR-TB risk probability of the training set were 0.904, 0.921, and 0.908, respectively, and those of the validation set were 0.954, 0.970, and 0.919, respectively. Conclusion:Through this nomogram model, clinicians could precisely predict the risk of incident MDR-TB among individuals with PTBH in the clinical practice.

Background: Assessment of disease severity of ulcerative colitis (UC) is crucial for the decision of drug treatment strategy, the appraisal of response to drugs, and the prognosis evaluation. Aims: To establish and validate a discriminant model for the quantification of disease severity of UC. Methods: The clinical data of 169 active UC cases admitted at the Beijing Haidian Hospital were analyzed retrospectively. Based on Truelove-Witts criteria, seven widely accepted indices including temperature, pulse, defecation frequency, hematochezia, hemoglobin (Hb), erythrocyte sedimentation rate (ESR) and albumin (Alb) were selected and a stepwise discriminant analysis was performed to establish a discriminant model using Fisher's linear discriminant function, and then the discriminant model was validated from different aspects. Results: The discriminant model: F1 (mild)=-51.109+0.587X1+0.295X2+0.379X3+0.071X4; F2 (moderate)=-49.905+0.624X1+0.512X2+0.333X3+0.095X4; F3 (severe)=-57.294+0.709X1+0.599X2+0.296X3+0.141X4 [ X1, pulse (beats /min); X2, defecation frequency (times/d); X3, Hb (g/L); X4, ESR (mm/h)]. The result of the newly established discriminant model was moderately correlated with the Truelove-Witts criteria (r

Objective:To explore the effects of evidence-based nursing in improving disease activity and function of patients with ankylosing spondylitis (AS) , so as to provide a theoretical basis for the actual promotion of evidence-based nursing.Methods:From October 2018 to October 2019, convenience sampling was used to select 80 AS patients admitted to Ningbo Hwa Mei Hospital of the University of Chinese Academy of Sciences as the research object. The selected patients were divided into the intervention group and the control group with the method of random number table, each with 40 cases. At the end of the study, 7 cases were lost to follow-up, and a total of 73 patients completed the study, and there were 36 cases in the intervention group and 37 cases in the control group. The control group carried out conventional nursing, and the intervention group implemented evidence-based nursing on the basis of conventional nursing. The Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) score, Bath Ankylosing Spondylitis Functional Index (BASFI) score and functional exercise compliance score of the two groups were compared before intervention, half a year after intervention, and one year after intervention.Results:The BASDAI, BASFI and functional exercise compliance scores of the two groups of patients had inter-group effects, time effects, and interaction effects between groups and time, and the differences were statistically significant ( P<0.05) . After the intervention, the BASDAI and BASFI scores of the intervention group were lower than those of the control group, and the compliance score was higher than that of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:Functional exercise direction based on evidence-based nursing can effectively improve the disease condition, function and functional exercise compliance of AS patients, and its intervention effect is better than conventional nursing.

Objective:To explore the effect of the evidence-based "one disease, one product" rehabilitation nursing in patients with ankylosing spondylitis, so as to provide a reference for the clinical nursing of patients.Methods:From November 2017 to October 2019, convenience sampling was used to select 200 patients with ankylosing spondylitis hospitalized in the Department of Rheumatology and Immunology, Hwa Mei Hospital, University of Chinese Academy of Sciences as the research object. According to the random number table method, patients were randomly divided into control group and observation group, each with 100 cases. Control group was given conventional nursing, and observation group conducted the "one disease, one product" rehabilitation nursing. We compared the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) , Bath Ankylosing Spondylitis Disease Function Index (BASFI) , Bath Ankylosing Spondylitis Disease Measurement Index (BASMI) and the functional exercise compliance score before and after the intervention between the two groups of patients.Results:After the intervention, the improvement of the disease activity, function and measurement index of observation group was better than that of control group, and the exercise compliance was higher than that of control group. The difference was statistically significant ( P<0.05) . Conclusions:The evidence-based "one disease, one product" rehabilitation nursing improves the patients' spinal function, reduces the patients' disease activity and joint stiffness, and improves the patients' compliance with rehabilitation, which is worthy of clinical application.
