Objective:To explore the health behavior of middle-aged and young stroke patients and analyze its influencing factors.Methods:From April to July 2023, convenience sampling was used to select 172 middle-aged and young stroke patients admitted to the First Affiliated Hospital of Naval Medical University as the research subject. A survey was conducted using the General Information Questionnaire, Health Behavior Scale for Stroke Patients, Health Belief Scale, and Multidimensional Scale of Perceived Social Support. Spearman correlation was used to analyze the correlation between health behavior, social support, and health beliefs among middle-aged and young stroke patients. Multiple linear regression was used to analysis the influencing factors of health behavior among middle-aged and young stroke patients. A total of 172 questionnaires were distributed, and 8 questionnaires with missing items and short response times were excluded, and 164 valid questionnaires were collected, with a valid response rate of 95.34%.Results:Among 164 middle-aged and young stroke patients, the total score of the Health Behavior Scale for Stroke Patients was 64.50 (57.00, 80.75), and the average score of the items was 2.58 (2.28, 3.23). Multiple linear regression analysis showed that factors affecting the health behavior of middle-aged and young stroke patients were whether it was the first onset, the time required to reach nearby medical institution, health belief, and social support ( P<0.05) . Conclusions:The health behavior of middle-aged and young stroke patients is above the medium level. In the process of intervening in the health behavior of middle-aged and young stroke patients, medical and nursing staff should pay attention to patients with recurrent stroke and poor access to medical services, while also improving patients' health belief and social support to promote patients' health behavior and reduce stroke recurrence.

Objective:To explore the mediating effect of coping style on disease perception and pre-hospital delayed behavioral intention in patients with acute ischemic stroke.Methods:This study was a cross-sectional study. From February to July 2023, convenience sampling was used to select 205 patients with acute ischemic stroke admitted to the First Affiliated Hospital of Naval Medical University as the study subject. The survey was conducted using the General Information Questionnaire, Stroke Pre-Hospital Delay Behavior Intention, Brief Illness Perception Questionnaire, and Simplified Coping Style Questionnaire.Results:205 questionnaires were filled out, 195 valid questionnaires, and the validity rate of the questionnaire was 95.1%. The Stroke Pre-Hospital Delay Behavior Intention score of patients with acute ischemic stroke was (63.61±16.12). Pre-hospital delayed behavioral intention in patients with acute ischemic stroke was positively correlated with disease perception and negative coping ( r=0.360, 0.266; P<0.01), and negatively correlated with positive coping ( r=-0.279, P<0.01). The mediating effects of positive and negative coping on disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients were 0.111 and 0.097, respectively, accounting for 26.89% and 23.49% of the total effect. Conclusions:There is a partial mediating effect of coping strategies between disease perception and pre-hospital delayed behavioral intention in ischemic stroke patients. In the process of stroke management, medical and nursing staff can reduce pre-hospital delayed behavioral intentions by improving disease cognition and coping style.

Chinese medicine self-assembly nano-strategies（CSAN） is to utilize the self-assembly property of Chinese medicine components， so that the Chinese medicine components can self-assemble to form structurally stable nano-preparations through non-covalent interactions. The formation of Chinese medicine self-assembly nano-preparations is often a synergistic result of a variety of non-covalent interactions， and many Chinese medicine monomers are susceptible to self-assembly due to their structural characteristics， and the phenomenon of self-assembly of Chinese medicine is also common in the decoction of single or compound Chinese medicine， which has attracted the attention of researchers. It is found that CSAN can improve the solubility and bioavailability of active components in Chinese medicine， which is of positive significance for the development and application of insoluble components of Chinese medicine. The self-assembly phenomenon of Chinese medicine decoction is closely related to the therapeutic efficacy， and the study of self-assembly phenomenon of Chinese medicine will bring a new perspective for the explanation of the mechanism of Chinese medicine decoction. At the same time， traditional Chinese medicine（TCM） has unique advantages in the field of anti-tumor. The application of CSAN in the field of oncology can not only exert the anti-tumor effect of the active components of Chinese medicine directly， but also act as a natural nano-carrier to carry chemotherapy drugs for combination chemotherapy， improve the targeting of drugs， enhance the anti-tumor efficacy， and reduce the side effects of chemotherapy， which has excellent anti-tumor potential. The preparation method of Chinese medicine self-assembly nano-preparations is simple， low cost， and has better safety than traditional nano-preparations， which is conducive to the promotion of the clinical transformation of nano-preparations， and also helps to provide new strategies and perspectives for promoting the modernization of TCM. Therefore， based on a large number of researches in this field in recent years， this paper reviewed the formation mechanism， different assembly forms， formation conditions and stability of Chinese medicine self-assembly nano-preparations by searching databases such as China national knowledge infrastructure（CNKI）， PubMed， WanFang data and VIP， and summarized the application of CSAN in different tumor therapies， providing a reference for further research on CSAN.

Objective:To investigate the impact of " staging" hybrid coronary artery revascularization (HCR) on the short-and long-term efficacy of patients with multiple coronary artery lesions.Methods:A retrospective case-control study was conducted. Eighty patients with multiple coronary artery lesions admitted to the Baoding Second Central Hospital from January 2017 to October 2018 were selected and divided into two groups according to different surgical methods. Forty patients were treated with " staging" HCR and were designated as the HCR group, and 40 patients were treated with off-pump coronary artery bypass grafting (OPCAB) and were designated as the OPCAB group. The perioperative related indicators and perioperative serious complications were compared between the two groups. The serum myocardial injury marker levels were detected preoperatively and 48 hours postoperatively, including heart-type fatty acid binding protein (H-FABP) and troponin I (cTnI). All subjects were followed up for at least 3 years to calculate the incidence of major adverse cardiovascular and cerebrovascular events (MACCE).Results:The bypass surgery time, mechanical ventilation time, ICU stay time, and total hospital stay time in the HCR group were all less than those in the OPCAB group (all P<0.05), and the incision length in the HCR group was shorter than that in the OPCAB group ( P<0.05). The intraoperative bleeding volume, postoperative 24-hour drainage volume, red blood cell transfusion volume, and plasma transfusion volume in the HCR group were all less than those in the OPCAB group (all P<0.05). Forty-eight hours after surgery, the serum H-FABP and cTnI levels in both groups were significantly higher than those preoperatively (all P<0.05), but the increase was more significant in the OPCAB group (all P<0.05). The perioperative serious complication rate in the HCR group was 2.50%(1/40), which was significantly lower than that in the OPCAB group [20.00%(8/40)] ( P<0.05). During the 3-year follow-up after surgery, the MACCE incidence in the HCR group was 12.50%(5/40), and that in the OPCAB group was 22.50%(9/40). There was no significant difference in the long-term MACCE incidence between the two groups ( P>0.05). Conclusions:" Staging" HCR treatment for multiple coronary artery lesions can achieve ideal surgical results. Compared with OPCAB, its short-term efficacy is more significant, and long-term efficacy is equivalent.

Objective:To compare the efficacy and safety of ticagrelor and clopidogrel in antiplatelet aggregation after 2-staged hybrid coronary revascularization (HCR).Methods:A prospective randomized controlled trial was conducted. According to the postoperative antiplatelet therapy scheme, the patients with coronary artery multivessel disease who underwent 2-staged HCR operation in our hospital were divided into ticagrelor group (after the operation, the patients were given aspirin enteric coated tablets 100 mg orally once daily and ticagrelor tablets 90 mg orally twice daily for 1 year) and clopidogrel group (after the operation, the patients were given aspirin enteric coated tablets 100 mg orally once daily and ticagrelor tablets 75 mg orally once daily for 1 year). The general condition, platelet aggregation funtion [maximum platelet aggregation rate (MPAR) and P2Y12 reaction unit (PRU) ] at different time points before and after operation, and platelet inhibition rate [aspirin resistance (AA), ticagrelor or clopidogrel resistance (ADP)], major adverse cardiovascular events (MACE), bleeding events, and adverse reactions after operation were analyzed and compared between the 2 groups.Results:A total of 124 patients were enrolled in the study, 62 patients each in the ticagrelor group and clopidogrel group. There were no statistically significant differences in baseline data (gender, age, New York Heart Association cardiac function classification, concomitant diseases, etc.) between the 2 groups (all P>0.05). The MPARs at 24 h, 7 d, and 1 month after operation in the ticagrelor group and clopidogrel group were lower than those before operation [(50±9)%, (36±8)%, (29±6)% vs. (65±11)% and (59±10)%, (47±9)%, (38±7)% vs. (65±12)%, all P<0.001]. The MPARs at 24 h, 7 d, and 1 month after operation in the ticagrelor group were lower than those in the clopidogrel group[(50±9)% vs. (59±10)%, (36±8)% vs. (47±9)%, (29±6)% vs. (38±7)%, all P<0.001]. The PRUs at 24 h, 7 d, and 1 month after operation in the 2 groups were lower than those before operation (all P<0.001). The PRUs at 24 h, 7 d, and 1 month after operation in the ticagrelor group were lower than those in the clopidogrel group(all P<0.001). There was no significant difference in the incidence of AA 24 hours after operation between the 2 groups ( P>0.05); the inhibition rate of ADP in the ticagrelor group was higher than that in the clopidogrel group ( P<0.001). At the 24th month of follow-up, the incidence of MACE in the ticagrelor group was lower than that in the clopidogrel group (11.3% vs. 27.4%, P<0.05). At the 12th month of follow-up, there was no statistically significant difference in incidence of bleeding events between the 2 groups (3.2% vs. 8.1%, P>0.05) . There was no statistically significant difference in the incidence of adverse reactions between the 2 groups (16.1% vs. 11.3%, P>0.05) . Conclusions:Compared with clopidogrel+aspirin regimen, ticagrelor+aspirin regimen is more effective in inhibiting platelet aggregation and reducing postoperative MACE after 2-staged HCR. Both antiplatelet aggregation regimens do not increase the risk of bleeding and have no serious adverse reactions. Both regimens have good safety.
