Objective:To explore the developmental trajectory and influencing factors of self-management behavior among stroke patients.Methods:A total of 478 ischemic stroke patients admitted to the department of neurology of a grade-Ⅲ hospital in Henan Province from July 2023 to June 2024 were selected as the investigation objects. Baseline data of patients were collected using the general situation questionnaire, stroke knowledge questionnaire, stroke health belief scale, stroke self-management behavior scale and self-rating depression scale. The self-management behavior level of patients was assessed at discharge, 1 month, 3 months and 6 months after discharge. Mplus 7.0 software was used to conduct trajectory analysis of stroke patients' self-management behaviors, and multiple Logistic regression analysis was used to analyze the influencing factors associated with the development trajectory types of different stroke self-management behaviors.Results:The self-management behavior scores of stroke patients at discharge, 1 month, 3 months and 6 months after discharge were 206.59(167.59, 230.57), 169.59(129.73, 196.73), 149.82(120.89, 171.48), and 147.14(123.02, 181.64), respectively. Four trajectory categories were described. Category 1 was low-level pattern of initial decrease followed by stabilization, accounting for 16.95%(81/478)( P<0.001, intercept=2.701). Category 2 was low-level pattern of initial decrease followed by increase, accounting for 12.97%(62/478)( P<0.001, intercept =2.696). Category 3 was medium-level pattern of initial decrease followed by stabilization, accounting for 57.11%(273/478)( P<0.001, intercept =3.829). Category 4 was high-level pattern of initial decrease followed by increase, accounting for 12.97%(62/478)( P<0.001, intercept=4.366). The self-management behavior of stroke patients with low level of stroke knowledge, low level of health belief, aged 60 to 70 years old, residence in rural areas and middle school and below education level were more likely to belong to the low level group(all P<0.05). Patients with low depression in the low level group were more likely to be classified as low-level pattern of initial decrease followed by increase( P<0.05). Conclusion:The trajectory category of self-management behavior could be predicted by stroke knowledge level, health belief level, age, place of residence, educational background and depression. Their self-management behavior level may be improved through targeted interventions according to the characteristics of different trajectory categories.

Objective:To investigate the feasibility, efficacy, and safety of CT- and bronchoscopy-guided 125I seed implantation in the treatment of central lung cancer complicated with atelectasis. Methods:Retrospective analysis was conducted on twenty-nine patients who were treated from May 2016 to Oct 2019 in the Second Hospital of Tianjin Medical University for central non-small-cell lung carcinoma complicated with pulmonary atelectasis that was inoperable due to medical reasons. 125I seeds were implanted into the trachea under the guidance of bronchoscopy first.The 125I seeds were then implanted into the hilum of the lungs by percutaneous puncture under the guidance of the CT and template.The seed activity was 18.5-29.6 MBq, and the prescription dose was 120 Gy.TPS planning and quality verification were performed before and after the operations.The rate of atelectasis recanalization, the satisfactory rate of dose verification, the improvement of dyspnea index, the survival time, and the adverse events during and after operation were observed. Results:All 29 patients with lung cancer complicated with atelectasis successfully completed the seed implantation, and the satisfactory rate of quality verification was 93.1%.The rate of atelectasis recanalization at 2, 6, 12, 18, and 24 months was 93.1%, 89.7%, 78.6%, 76.2%, and 60%, respectively.Their dyspnea and anoxia symptoms were significantly relieved in 5-28 months after treatment.The results showed that the patients′ dyspnea index was 2.8-0.8 before treatment and 1.4-0.9 after treatment.The median follow-up period was 20 months and median survival was 21 months.Adverse events associated with the radiation therapy included pneumothorax, hemoptysis, cough, fever, and particle displacement.No level-3 or more serious adverse events occurred.Conclusions:The CT- and bronchoscopy-guided 125I seed implantation is a safe and effective therapy option for the treatment of central non-small-cell lung carcinoma associated with atelectasis.It contributes to a high rate of local recanalization, and can rapidly improve clinical conditions and quality of life of the patients with few adverse reactions.

Objective To investigate the effects of different BIS values on postoperative cogni-tive dysfunction (POCD)and S100βprotein(S100β)in the early stage of postoperation.Methods Fifty patients who were scheduled for selective abdominal surgery under general anesthesia (male 34 cases, female 1 6 cases,aged 65 to 75 years,ASA Ⅰ or Ⅱ)were randomly divided into two groups:light anesthesia group (group L,n =25,BIS value was maintained at 50 to 59)and deep anesthesia group (group D,n =25,BIS value was maintained at 30 to 39).BP,HR,SpO 2 ,ECG,PET CO 2 ,inhaled anes-thetic concentration and BIS values were recorded on time points of 5 minutes after the patients ente-ring the operating room (T0 ),before endotracheal (T1 ),intubation (T2 ),incision (T3 ),two hours after incision (T4 ),three hours after incision (T5 )and at the end of surgery (T6 ).The procedure du-ration,anesthesia time,dosages of propofol,fentanyl,midazolam and VAS scores on 1 d after sur-gery were also recorded.Blood samples were collected on time points of 10 min before anesthesia,im-mediately after surgery and 24,48 h after operation.S100β concentration were detected.Mini-mental State Examination (MMSE)score and Trail Making Test (TMT)completion time were recorded on 1 d before surgery and 1,3,7 d after surgery.Results BIS value of group D were lower than group L on T2 ,T3 and T4 .The propofol dosage of group D was significantly greater than that in group L (P <0.05 ).The concentration of serum S100βincreased significantly immediate and 48 h after operation in both groups compared with 10 min before anesthesia(P < 0.05).It was still higher 24 hours after op-eration than before anesthesia.But there was no statistic difference.Compared with the end of surger-y,the concentration of serum S100βin two groups on 24 h after surgery were significantly decreased (P < 0.05 ).The concentration of serum S100β in group L on the end of surgery and 24 h after surgery were higher than that in group D significantly (P <0.05).Compared with 1 d before surgery, postoperative 1 d MMSE scores in two groups and postoperative 3 d MMSE score in group L de-creased significantly (P <0.01).Compared with postoperative 3 d,postoperative 7 d MMSE score in group L increased significantly (P <0.01).Postoperative 1,3 d MMSE score in group D were signifi-cantly higher than group L (P <0.05).Compared with 1 d before surgery,TMT completion time in two groups on 1 d after surgery were significantly prolonged (P <0.01 ).Compared with 1 d after surgery,TMT completion time in two groups on 3 d after surgery were significantly shortened (P <0.01).Compared with 3 d after surgery,TMT completion time in group L on 7 d after surgery was significantly shortened (P <0.01 ).TMT completion time in group D on 1,3 d postoperative were significantly shorter than group L (P <0.05).POCD incidence of group D on 1 d after surgery was lower than that in group L (P < 0.05).Conclusion Different depth of anesthesia can ensure hemo-dynamic balance in old patients during surgery and after surgery.When BIS value was maintained at 30 to 39,it had lower S100βprotein levels,lower incidence of early POCD and a lesser degree of post-operative cognitive dysfunction.
