Objective:To explore the potential facilitators and barriers to healthy behavior among stroke patients.Methods:Semi-structured interviews were conducted among 16 stroke patients from September 2022 to March 2023 using an objective sampling method.The interview guide was developed using the theoretical domain framework(TDF). Interviews were transcribed and refined the theme using directed content and induction analysis.Using the TDF as the initial coding framework, the themes were then merged into the most relevant domains.Finally, the correspondence between theoretical domains and the healthy behavior of stroke patients was determined based on the frequency and relationship between themes.Results:This study identified nine theoretical domains that affected the healthy behavior of stroke patients: knowledge, skills, motivation and goals, social influences, social/professional role and identity, environment context and resources, belief about capability, consequence belief and behavioral regulation.Conclusion:The healthy behavior of stroke patients is complex and influenced by several factors.The nine theoretical domains identified in this study will provide recommendations for future healthy behavior interventions for stroke patients.

Epilepsy is a kind of brain dysfunction syndrome characterized by paroxysmal,transient,repetitive and rigid characteristics caused by abnormal discharge of highly synchronized neurons in the brain.Epilepsy is often accompanied by cognitive dysfunction.At present,anti-seizure medications are the most important methods of clinical treatment.Most of the traditional anti-seizure medications can cause cognitive dysfunction,and the influence of new anti-seizure medications on cognitive function is not completely clear.This paper reviews the influence of new anti-seizure medications on cognitive function and the possible related mechanisms of action based on relevant literature at home and abroad.It is expected that clinicians should pay attention to cognitive function in the process of diagnosis and treatment of epilepsy,and help clinicians realize the influence of anti-seizure medications on cognitive function,and rationally choose anti-seizure medications for patients.

Objective We aimed to explore the therapeutic mechanism of electroacupuncture at Yintang(EX-HN3),Neiguan(PC6)and Zusanli(ST36)on the Hypothalamic-Pituitary-Adrenal axis(HPA)of functional dyspepsia(FD)rats.Methods Forty SD rats were randomly divided into blank group,model group and EA group.The FD model was replicated by tail clamping,irregular diet,and filling the stomach with ice of Saline Solution.After modeling,the EA group received acupuncture treatment for 1 time day,30 minutes time,for 14 days.Recording the general state of the rat.Detection of locomotion and catatonia in rats by open field test.HE staining to observe the morphology and inflammation of gastric mucosa in rats.PCR detection of mRNA expression of 5-hydroxytryptamine3 receptor and corticotropin-releasing hormone in rat hypothalamus.Detection of corticotropin-releasing hormone receptor-2 and NOD-like receptor protein 6 inflammasome protein expression in rat duodenum by Western blotting.Alcian blue staining was used to detect the expression of rat duodenum goblet cells.Results Compared with the blank group,the general state,distance,speed,duodenum CRHR2 and NLRP6 proteins in the model group were significantly decreased(P<0.05),the hypothalamic 5-HT3R and CRH mRNA were significantly increased(P<0.05).Compared with the model group,the general state,distance,speed,expression of CRHR2,NLRP6 protein and goblet cells in the duodenum of rats in the EA group were significantly increased(P<0.05),the 5-HT3R and CRH mRNA in the hypothalamus were significantly decreased(P<0.05).In the model group,the connective tissue of the gastric mucosa was loosely arranged,the submucosa had mild edema,and there were some lymphocytes.The connective tissue of the gastric mucosa of the rats in the blank group and the electroacupuncture group was closely arranged,and there was no obvious proliferation of interstitial cells and no inflammatory cells.Conclusion EA can increase the expression of CRHR2,NLRP6 protein and goblet cells in the duodenum,and inhibit the expression of 5-HT3R and CRH in the hypothalamus.EA can improve gastrointestinal motility and locomotion,relieve anxiety,repair the mucosal barrier of the defective intestine,and restore the function of the Hypothalamic-Pituitary-Adrenal axis.

The components of the tumor microenvironment have a complex composition and play an important regulatory role in tumor evolution.The extracellular matrix(ECM)serves as a vital mediator in regulating cancer advancement within the TME.Incorporating ECM into tumor modeling allows for a more comprehensive simulation of the TME in vitro.As a medium for organoid growth,the matrix gel fulfills the functions of ECM.ECM is normally derived from the recombinant basement membrane of mouse sarcoma(Matrigel);however,batch-to-batch variations in Matrigel affect experiment reproducibility.To overcome such issues,researchers have designed synthetic matrix gels.This paper provides an overview of the current research in the application of matrix gels for tumor organoid modeling,offering insights for continuous optimization of organoid culture,thereby achieving more efficient and cost-effective organoid construction and advancing the translation of basic research to clinical applications.

Objective:To explore the latent classes of health behavior and explore the predictive factors among stroke patients.Methods:A total of 1 250 participants were recruited using cluster random sampling in September 2022. The general information, the modified Rankin scale(mRS), stroke prevention knowledge questionnaire(SPKQ), health behavior scale for stroke patients (HBS-SP), and short form-health belief model scale (SF-HBMS) were administered in the cross-sectional survey. Mplus 8.3 software was used to conduct a latent class analysis (LCA) on the health behavior of stroke patients, and SPSS 27.0 software was used to carry out multinomial Logistic regression to analyze the predictive factors of different latent classes of health behavior of stroke patients.Results:The health behavior of stroke patients obtained three latent classes: low health behaviors-lack of health responsibility group (66.9%, n=794), moderate health behaviors-poor compliance group (11.9%, n=141), and good health behaviors-insufficient exercise group (21.2%, n=251). Compared with good health behaviors-insufficient exercise group, stroke patients with shorter duration education time ( B=-0.589, OR=0.555, P=0.036), hemorrhagic stroke ( B=0.082, OR=1.086, P<0.001), fewer comorbidities ( B=-0.022, OR=0.978, P=0.026), higher mRS score ( B=-0.046, OR=1.047, P=0.004), lower SPKQ score ( B=-0.055, OR=0.947, P=0.016), and lower SF-HBMS score ( B=-0.085, OR=0.919, P<0.001) were more likely to be included in moderate health behaviors-poor compliance group. However, stroke patients with shorter duration education time ( B=-0.026, OR=0.974, P=0.003), rural areas dwelling ( B=0.800, OR=2.225, P=0.004), fewer comorbidities ( B=-0.056, OR=0.945, P<0.001), lower SPKQ score ( B=-0.101, OR=0.904, P<0.001), and lower SF-HBMS score ( B=-0.071, OR=0.931, P<0.001) were more likely to be included in low health behaviors-lack of health responsibility group. Conclusion:The health behavior of stroke patients has three latent classes. A targeted intervention should be carried out according to the characteristics of different classes to improve their health behavior levels.

Objective: To evaluate the residual radioactivity after ¹³¹I treatment in postoperative inpatients with differentiated thyroid carcinoma (DTC) using service robot in nuclear medicine ward, and assess the time for patients to be released from isolation. Methods: From September 2017 to June 2018, 297 patients (94 males, 203 females, age: 19-80 years) with DTC who underwent ¹³¹I treatment after surgery were included. According to the purpose of treatment and the prescription dosage of ¹³¹I, patients were divided into 8 groups: 4 groups accepted ¹³¹I remnant ablation therapy (RAT) with different dosages, which were 3 700 MBq (RAT1, n=34), 4 440 MBq (RAT2, n=122), 5 550 MBq (RAT3, n=81) and 7 400 MBq (RAT4, n=27), respectively; 4 groups had ¹³¹I treatment for recurrent/metastatic lesions (RMLT), and the dosages were 3 700 MBq (n=1), 4 440 MBq (n=2), 5 550 MBq (n=14) and 7 400 MBq (n=16). At 4, 24, 48 and 72 h after ¹³¹I administration, the dose equivalent rates at 2 cm away from the patient′s neck and at 1 m away from the body were measured by the robot designed for nuclear medicine ward. Kruskal-Wallis rank sum test and Mann-Whitney U test were used to analyze the data. Results: Neck dose equivalent rates for patients with RAT at different time points (4, 24, 48 and 72 h) after ¹³¹I administration were significantly different among 4 groups (H values: 20.889-46.410, all P<0.05), as well as the body dose equivalent rates (H values: 27.181-35.497, all P<0.05). The neck dose equivalent rates at 24, 48 and 72 h after ¹³¹I administration were statistically different between group 3 and 4 for patients with RMLT (z values: 2.328-3.076, all P<0.05; data in group 1 and 2 were too limited to be compared), while there was no statistical difference for the body dose equivalent rates (z values: 0.333-1.621, all P>0.05). The radioactivity retention in patients decreased rapidly within 24 h, then slowed down gradually and became extremely low at 72 h. At 72 h after ¹³¹I administration, 96.6%(255/264) patients with RAT and 100%(33/33) patients with RMLT were lower than 23.3 μSv/h, which meant the patients could be discharged from hospitalization. Conclusions Nuclear medicine ward service robots may dynamically measure residual radioactivity in DTC patients who take ¹³¹I treatment, providing individualized isolation solutions.
