ObjectiveTo investigate the demand and the application outcomes of case-based learning (CBL) combined with teaching case library in continuing education courses for rehabilitation therapists. MethodsA convergent mixed-methods research design was adopted, involving 51 rehabilitation therapists and 31 instructors who participated in the advanced training program at the Department of Rehabilitation Medicine, Peking University Third Hospital between October, 2022 and October, 2024. Self-developed questionnaires were used to collect data on the perceived needs of teachers and students regarding CBL and teaching case library. Differences between CBL + teaching case library and traditional lecturing in student evaluations, classroom participation and interaction were compared using Student Evaluation of Teaching in Medical Lectures, Classroom Participation Scale and Flanders Interaction Analysis System. Semi-structured interviews were conducted to obtain evaluations and attitudes towards this method from both instructors and students' perspectives. ResultsThe survey showed that 91.4% of participating teachers and students supported the use of CBL in the courses, and 82.7% advocated that the teaching case library should include typical cases. Significant differences were observed in teaching preference between teachers and students (χ² = 17.597, P < 0.01). Application effects demonstrated that CBL+teaching library significantly outperformed traditional teaching methods in student previewing behaviors, classroom interaction and learning outcomes (|Z| ≥ 2.646, P < 0.01). Flanders Interaction Analysis indicated that CBL+teaching library was superior to traditional teaching in terms of students' motivation to speak and autonomous learning. Qualitative Research generated four positive themes including cultivating clinical reasoning, being close to clinical practice, deepening knowledge understanding and improving teaching quality; and three negative themes including increasing teaching burden, high software and hardware requirements and posing great challenges to students were generated. ConclusionCompared with traditional teaching methods, CBL combined with teaching case library is closely linked to clinical practice, facilitating students' clinical reasoning, enhancing teaching effectiveness and satisfaction, and therefore aligning with the goals and needs of continuing education for rehabilitation therapists, which is highly recognized by both instructors and students.

As the incidence of autism rises annually,its unknown pathogenesis makes it challenging to treat the varied repetitive and stereotyped behaviors that characterize its core symptoms.The striatum is an important brain region for the control of locomotor behaviors,featuring a unique mosaic structure,complex neural origin,and finely regulated developmental process that is highly susceptible to genetic and environmental influences.Both clinical and basic studies have indicated that abnormal development of the striatal nuclei may contribute to the pathogenesis of these repetitive stereotyped behaviors in autism.Clinical imaging data have primarily identified gross anatomical variations in the stratum(e.g.,its general outline),but lack the resolution necessary to detect the cellular and subcellular alterations within the region.By introducing the abnormalities in the spatiotemporal development of the striatum and their links to the characteristic behaviors of autism,this review aims to advance our understanding of the role of the striatum in autism pathogenesis and to inform future animal studies and clinical research.

Objective:To analyze the latent prevalence of hepatitis B and type 2 diabetes and their correlation through an observational study.Methods:This study used a case-control design. The cases with diabetes were recruited through the diabetes management system and village doctors, while the controls without diabetes were screened from volunteers recruited by village health clinics. Capillary blood samples were collected from the study participants for the measurement of real-time blood glucose level, and venous blood samples were taken from them for the detections of HBV serological markers. Firth logistic regression model was used to fit the relationship between HBsAg positive status and diabetes status.Results:The study included 1 218 diabetes patients, 62 patients with impaired fasting glucose and 491 cases without diabetes. In the cases without diagnosis of diabetes, 11.15% had impaired fasting blood glucose and 4.43% had diabetes. Among those who reported no or unknown diagnosis of hepatitis B, 1.73% were positive for HBsAg, while 18.80% were positive for both HBV core antibody and surface antibody, indicating latent infection of hepatitis B virus. In the non-diabetes group, 0.81% reported hepatitis B history, and in the diabetes group, 2.76% reported hepatitis B history. After adjustment, the HBsAg positive rate was higher in the diabetes group ( OR=2.90, 95% CI: 1.21-6.91). Conclusions:Both diabetes and hepatitis B exhibited a high degree of latent prevalence. The HBsAg positive rate was significantly higher in those with diabetes than in those without diabetes, indicating a potential correlation. These findings highlighted the importance of strengthened screening and management of comorbidities.

Objective:Exploration of the immunogenicity and persistence of three different immunization regimens of hepatitis B vaccines in diabetic patients.Methods:Participants with diabetes and non-diabetic individuals were recruited from study sites and assigned to different vaccination regimens: the diabetic group (①D60Yeast0-1: received 60 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-month schedule; ②D20Yeast0-1-6: received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule; ③D20CHO0-1-6: received 20 μg Chinese hamster ovary (CHO) cell-derived recombinant HBV vaccine on a 0-1-6-month schedule) and the non-diabetic group (ND20Yeast0-1-6: non-diabetic individuals received 20 μg Saccharomyces cerevisiae-derived recombinant HBV vaccine on a 0-1-6-month schedule). Venous blood samples were collected at 1,12, and 48 months post-full vaccination to measure anti-HBs levels. Differences in immunogenicity between diabetic and non-diabetic groups, as well as among diabetic subgroups, were analyzed.Results:This study enrolled a total of 564 subjects. In the D20CHO0-1-6 group, the seroconversion rate decreased from 90.72% (95% CI: 84.84%-96.60%) at 1 month to 74.23% (95% CI: 65.37%-83.08%) at 48 months, and the antibody geometric mean concentration (GMC) decreased from 676.08 (95% CI: 389.05- 1 148.20) mIU/ml at 1 month to 33.11 (95% CI: 23.44-46.77) mIU/ml at 48 months. In the D20Yeast0-1-6 group, the seroconversion rate declined from 93.81% (95% CI: 89.29%-98.32%) at 1 month to 63.72% (95% CI: 54.71%-72.72%) at 48 months, with antibody GMC dropping from 630.96 (95% CI: 407.40-954.99) mIU/ml to 25.70 (95% CI: 17.78-38.02) mIU/ml over the same period. For the D60Yeast0-1 group, seroconversion rate fell from 82.03% (95% CI: 75.29%-88.77%) to 56.25% (95% CI: 47.54%-64.96%), and antibody GMC decreased from 81.28 (95% CI: 51.29-128.82) mIU/ml to 15.49 (95% CI: 11.75-20.89) mIU/ml between 1 and 48 months. The ND20Yeast0-1-6 group (non-diabetic control) exhibited a higher initial seroconversion rate of 97.56% (95% CI: 94.80%- 100.00%) at 1 month, but it still declined to 76.42% (95% CI: 68.82%-84.03%) at 48 months, with antibody GMC decreasing from 1 318.30 (95% CI: 912.01- 1 905.50) mIU/ml to 34.67 (95% CI: 25.12-47.86) mIU/ml. Multivariate analysis on factors influencing the GMC of antibodies revealed statistically significant differences in antibody GMC between the D20Yeast0-1-6 group and ND20Yeast0-1-6 group at 12 months (a OR=0.73, 95% CI: 0.58-0.93) and 48 months (a OR=0.79, 95% CI: 0.63-0.99) post-vaccination (all P<0.05). As for the diabetic population, when compared with the D20Yeast0-1-6 group, the D60Yeast0-1 group also showed statistically significant differences in antibody GMC at 12 months (a OR=0.57, 95% CI: 0.44-0.74) and 48 months (a OR=0.60, 95% CI: 0.47-0.76)(all P<0.05). Conclusions:The seroconversion rate and antibody GMC gradually decreased over time (1, 12, and 48 months) in the four groups. Diabetic patients showed poor immunogenicity and persistence to hepatitis B vaccines. The immunogenicity and persistence of hepatitis B vaccination in diabetic patients were associated with vaccine type, antigen dose, and vaccination regimen. The CHO cell-recombinant hepatitis B vaccine demonstrated better performance in terms of immunogenicity and persistence among the diabetic population.

BACKGROUND:Recent research indicates that disc degeneration is closely related to abnormal stress load,and mechanotransduction proteins play a key role in it. OBJECTIVE:To investigate the role and mechanism of mechanotransduction proteins in the mechanotransduction process induced by abnormal mechanical stimulation in disc degeneration,and to summarize the current treatment strategies targeting mechanotransduction to delay intervertebral disc degeneration. METHODS:Using"intervertebral disc,nucleus pulposus,annulus fibrosus,cartilaginous endplate,cell,mechanics,signal transduction,protein,biomechanics"as Chinese search terms,and"intervertebral disc,nucleus pulposus,annulus fibrosus,cartilaginous endplate,cell,mechanical stimulation,signal transduction,protein,biomechanics"as English search terms,relevant literature in the PubMed and CNKI databases was searched.A total of 88 articles were ultimately included for review. RESULTS AND CONCLUSION:Disc cells can sense external mechanical stimulation through various mechanotransduction proteins and convert it into biological responses within the cells.These transduction proteins mainly include collagen proteins in the extracellular matrix,cell membrane surface receptors(such as integrins and ion channels),and cytoskeleton structural proteins.Their regulation of mechanotransduction processes primarily involves the activation of multiple pathways,such as the PI3K/AKT signaling pathway,nuclear factor-kB signaling pathway,and Ca2+/Calpain2/Caspase3 pathway.Mechanotransduction proteins play a key role in the mechanotransduction of disc cells.Abnormal expression of these proteins or resulting changes in the extracellular matrix environment can disrupt the mechanical balance of disc cells,leading to disc degeneration.In-depth study of the expression and regulatory mechanisms of mechanotransduction proteins in disc cells,and identification of key pathological links and therapeutic targets,is of significant importance for developing treatment strategies for disc degeneration.Current strategies to delay intervertebral disc degeneration by targeting mechanotransduction mainly include regulation of transduction proteins and improvement of the extracellular matrix.However,research in this area is still in its early stages.As research continues,new breakthroughs are expected in the regulation of disc degeneration by mechanotransduction proteins.
