Myocardial fibrosis is a serious cause of heart failure and even sudden cardiac death. However, the mechanisms underlying myocardial ischemia-induced cardiac fibrosis remain unclear. Here, we identified that the expression of sterile alpha and TIR motif containing 1 (SARM1), was increased significantly in the ischemic cardiomyopathy patients, dilated cardiomyopathy patients (GSE116250) and fibrotic heart tissues of mice. Additionally, inhibition or knockdown of SARM1 can improve myocardial fibrosis and cardiac function of myocardial infarction (MI) mice. Moreover, SARM1 fibroblasts-specific knock-in mice had increased deposition of extracellular matrix and impaired cardiac function. Mechanically, elevated expression of SARM1 promotes the deposition of extracellular matrix by directly modulating P4HA1. Notably, by using the Click-iT reaction, we identified that the increased expression of ZDHHC17 promotes the palmitoylation levels of SARM1, thereby accelerating the fibrosis process. Based on the fibrosis-promoting effect of SARM1, we screened several drugs with anti-myocardial fibrosis activity. In conclusion, we have unveiled that palmitoylated SARM1 targeting P4HA1 promotes collagen deposition and myocardial fibrosis. Inhibition of SARM1 is a potential strategy for the treatment of myocardial fibrosis. The sites where SARM1 interacts with P4HA1 and the palmitoylation modification sites of SARM1 may be the active targets for anti-fibrosis drugs.

To summarize the perioperative nursing experience of a patient with the first multiple aortic valve operation in China implanted a new non-sutured biological heart valve. The main contents of nursing included through capacity management, prevention and control of bleeding and thrombocytopenia, arrhythmia monitoring and correction, infection prevention and control, analgesic sedation, prevention of related complications, whole-course psychological counseling and nutritional support. After careful treatment and nursing, the patient recovered well and was transferred out of ICU in 4 days and discharged in 10 days.

Objective:To evaluate the effect of different interventions in post-percutaneous coronary intervention (PCI) patients with kinesiophobia using network Meta-analysis.Methods:Computerized search of randomized controlled trials and quasi-experiment related to kinesiophobia interventions for post-PCI patients in WanFang database, China National Knowledge Infrastructure, China Biology Medicine, VIP database, Web of Science, PubMed, Cochrane Library and Embase was conducted with a time frame of searching from the establishment of the library to August 3, 2023. Literature screening, data extraction and literature quality evaluation were carried out independently by two researchers. Network Meta-analysis was performed using Stata 17.0 software.Results:A total of 13 literatures were included, including 9 randomized controlled trials and 4 quasi-experiments.Network Meta-analysis showed that cognitive behavioral therapy ( SMD = -4.08, 95% CI -6.49 --1.67), cognitive behavioral therapy combined with cardiac rehabilitation ( SMD = - 3.02, 95% CI -5.43 -- 0.61), dual heart medical intervention ( SMD = - 2.48, 95% , - 4.87 - - 0.09) can reduce the level of exercise fear in patients after PCI, and the difference were statistically significant compared with routine nursing (all P< 0.05). Ranked probability plots showed that the effects of the nine interventions in reducing kinesiophobia in post-PCI patients were cognitive behavioral therapy, cognitive behavioral therapy combined with cardiac rehabilitation, adaptive leadership theory-based intervention, dual heart medical intervention, COX health behavior interaction model, health education based on the behavioral change wheel, graded exposure therapy, mindfulness intervention, and high-intensity interval training in descending order of effectiveness. Conclusions:Cognitive behavioral therapy was the most effective intervention for kinesiophobia in post-PCI patients, but more high-quality randomized controlled trials are needed to further verify this conclusion.

【Objective】 To investigate the genotype of anti-HCV reactive blood donors by one ELISA assay and provide scientific basis for the reentry of anti-HCV false positive blood donors. 【Methods】 The data of 453 blood donors reactive to antibody to HCV(anti-HCV) with one ELISA assay(third generation) were extracted via the blood donor information system of Shaoguan Central Blood Station from January 1, 2014 to December 31, 2018. The subjects were recalled to the station for the serological retest, using a 4th generation ELISA reagent, and PCR qualitative test. The PCR reactive samples were sent to the genetic testing laboratory for HCV genotyping, in order to guide diagnosis and treatment in the future. Meanwhile, those PCR negative blood donors returned to be eligible again based on the Guidelines for the Return of Reactive Blood Donors for Blood Screening. 【Results】 70.2% (318/453) of the previous anti-HCV-reactive blood donors, using a third-generation ELISA assay responded to the HCV genotyping, of which 83.0%(264/318) were negative, and 17%(54/318) positive. The profile of HCV subtypes in positive donors was HCV2a>1b>3a=6a. A little bit high false positive rate was presented by the third, and former, generation reagent than the four generation(0.41% vs 0.06%), which was confirmed by HCV RNA qualitative and HCV genotyping tests.After two rounds of reentry testing, 98 eligible blood donors returned to the blood donor team, with the return rate at 21.63% (98 / 453). 【Conclusion】 NAT or (and) HCV genotyping for anti-HCV reactive blood donors screened out by the third, and former, generation, should be carried out to permanently shield the true positive donors and reenter the negative ones.

Objective To understand the status of fluoride content in brick tea (pressed tea) in China,and conduct health risk assessment according to the situation of drinking brick tea in fluorosis areas.Methods Twenty national designated brick tea manufacturers were selected to collect 1-5 varieties of brick tea samples of mainstream varieties with large production volume and large sales volume.If low-fluoride brick tea was produced,an additional sample would be collected to determine the fluoride content of tea.The retrospective analysis method was used to collect the monitoring data of brick tea-type fluorosis in the whole country in 2017,and analyze the use of brick tea in the residents of the brick tea-type fluorosis areas in six provinces (regions) of Inner Mongolia,Sichuan,Gansu,Ningxia,Xinjiang and Qinghai.According to the fluoride content of brick tea,combined with daily average consumption data of brick tea in the brick tea-type fluorosis areas,daily average brick tea intake,and hazard quotient of the daily average brick tea fluoride and the standard recommended fluoride intake were calculated.A health risk assessment was conducted based on the hazard quotient (hazard quotient ＞ 1 indicated a health risk).Through the total fluoride intake standard of the Chinese population,the safe consumption of brick tea with different fluoride content was simulated by using the value of the hazard quotient.The tea fluoride was measured by an ion selective electrode method.Results A total of 54 samples were collected,of which 49 were brick tea samples and 5 were low-fluoride brick tea samples.The geometric mean of the fluoride content of 49 brick tea samples was 460 mg/kg,the median was 430 mg/kg,and the range was 102-1 797 mg/kg.There were 14 samples with a fluoride content ＜ 300 mg/kg,accounting for 28.6％.The average fluoride content of 5 low-fluoride brick teasampleswas 193 mg/kg,ranging from 102 to 290 mg/kg.Forty-nine brick tea samples were distributed in 5 provinces,the fluoride content of brick tea was the lowest in Yunnan,128 mg/kg;the highest in Hubei,712 mg/kg.The lowest fluoride content of brick tea in different varieties was Tuo tea,130 mg/kg,and the highest was Jinjian tea,745 mg/kg.There were 1 000 households drinking brick tea in the brick tea-type fluorosis areas in 6 provinces,73.9％ (739/1 000) of households drinking the products of the national assigned brick tea manufacturers;a total of 1 000 brick tea samples were collected,and the geometric mean of brick tea fluoride content was 551 mg/kg,and only 17.5％ (175/1 000) of brick tea had a fluoride content ＜ 300 mg/kg.Compared with the national standards and the standards of World Health Organization,hazard quotient of agriculture,animal husbandry,semi-pastoral industry,urban residents through the brick tea fluoride was 0.34,1.38,0.75,and 0.21,respectively;0.29,1.21,0.66,and 0.19,respectively.Animal husbandry hada health risk through drinking brick tea among them.According to the health standard of total fluoride intake in China,when drinking brick tea with fluoride contents of 300,430,460 and 500 mg/kg,the safe consumption of brick tea for school-age children was 2.9,2.0,1.9 and 1.8 kg,respectively,and for adult was 4.3,3.0,2.8 and 2.6 kg,respectively.Conclusions Brick tea has high fluoride content,and percent of qualified brick tea is low and few of low-fluoride brick tea are consumed.There is a health risk in the animal husbandry who has a large amount of brick tea.

Objective: To explore the application of the King′s theory for the standardized training of new recruited nurses based on Tower platform. Methods: Totally 167 new recruited nurses were randomly divided into the intervention group (n=84) and the control group (n=83).

Objective To assess medication literacy status of outpatients and analyze the effect of medication literacy on medication adherence. Methods Outpatients were investigated with Medication Literacy Assessment scale and Medication Adherence Scale in Tianjin Chest Hospital, Tianjin Huanhu Hospital and the Second Hospital of Tianjin Medical University in August 2017. Results The average score of Medication literacy scale of 200 outpatients was 7.60 ± 2.98. There were significant differences among the scores of Medication Literacy Assessment scale of different ages(F=9.444, P＜0.05) and education levels(F=26.682, P＜0.05). Logistic regression analysis showed that medication literacy had an impact on medication adherence in outpatients (P＜0.05). The medication compliance of outpatients with high medication literacy was 2.336 times as high as who with medium medication literacy and 18.529 times as high as who with low medication literacy, and the medication compliance of outpatients with medium medication literacy was 7.925 times as high as who with low medication literacy. Conclusion The medication literacy of outpatients was at the middle level, and most of the outpatients were poor in adherence. The higher the medication literacy level was, the better the medication adherence was; the lower medication literacy level was, the poorer medication adherence was. The medical staff could improve the medication adherence by improving the medication literacy to ensure the health of outpatients.

Protozoan ciliates are a group of unicellular eukaryotes. The special characteristics of stop codons usage in termination of protein biosynthesis in ciliates cells makes them an ideal model to study the mechanism of stop codon recognition of polypeptides release factors. To localize the functional positions of biomolecules in ciliates cell, we constructed a macronuclear artificial chromosome containing a gene encoding red fluorescence protein (EoMAC_R) based on the structural characteristics of ciliates chromosome. Three factors, L11, eRF1a, and eRF3 that are involved in termination process of protein synthesis were colocalized in Euplotes octocarinatus cells by using novel EoMAC_R and the previously constructed EoMAC_G. The results indicated that protein synthesis mainly occurred inside the "C" shape macronucleus, suggesting that EoMAC could be a useful tool for localizing biomolecules in ciliates cell.
