Objective To evaluate the effect of the local del ivery of basic fibroblast growth factor 2 (bFGF-2) on the osseointegration around titanium implant of diabetic rats. Methods The bFGF-2-loaded poly (lactic-co-glycol ic acid) microspheres were prepared by water/oil/water (W/O/W) double-emulsion solvent evaporation method. Thirty-five male SPF level Sprague Dawley rats, weighing 220-250 g and aged 9 weeks, were selected as experimental animals. Ten rats were fedwith the routine diet as normal control group. The other 25 rats were made the diabetic animal model by giving high fat-sugar diet and a low dose streptozotocin (30 mg/ kg) intravenously; 20 rats were made the diabetic animal model successfully. Then 20 rats were randomly divided into diabetic control group (n=10) and bFGF-2 intervention group (n=10). A hole was drilled in the right tibia bone of all rats, and the titanium implant treated by micro-arc oxidation surface was planted into the hole. Simultaneously, the previously prepared microspheres and blood were mixed and were loaded on the surface of the implant before it was implanted into the rats of the bFGF-2 intervention group. At 4 and 8 weeks, the tibia containing implants was harvested, embedded with resin and made undecalcified tissue sl ices to compare the osseointegration. Results At 4 weeks, the implants of the normal control group were surrounded by new lamellar bone with continuity; whereas the tissue around the implants of the diabetic control group contained l ittle woven bone and some fibrous tissue; and obvious new formed bone with continuity was observed in bFGF-2 intervention group. At 8 weeks, the results of 3 groups were similar to those at 4 weeks. At 4 weeks, the percentage of bone-implant contact (BIC) in diabetic control group was significantly less than those in normal control group (P lt; 0.05) and in bFGF-2 intervention group (P lt; 0.05); the BIC in bFGF-2 intervention group was less than in normal control group, but showing no significant difference (P gt; 0.05). After 8 weeks, the BIC in normal control group and in bFGF-2 intervention group were significantly greater than that in diabetic control group (P lt; 0.05), but there was no significant difference between bFGF-2 intervention group and normal control group (P gt; 0.05). Conclusion Local del ivery of bFGF-2 around titanium implants may improve the osseointegration in diabetic rats.
Objective To systematically review the current situation, dilemmas and countermeasures of the regulation of health care integration services in China, and provide reference for the research on the regulation of health care integration services in China. Methods Studies and policies on the regulation of health care integration services were systematically searched from the inception of the databases to October 2022, and the included studies and policies were coded and analyzed by using the qualitative analysis software NVivo12. Results A total of 12 research articles and 15 policy announcements were included. The theoretical framework, regulatory dilemmas and regulatory countermeasures for the regulation of health care integration services were obtained through open coding, axial coding and selective coding. The regulatory framework of health care integration services was divided into five aspects: regulatory basis, regulatory subject, regulatory object, regulatory content and regulatory methods. The lack of regulatory basis led to dilemmas in the remaining aspects accordingly. Conclusion The regulation of health care integration services needs to start from the regulatory basis, introduce and improve the health care integration laws and policies, and gradually form a health care integration service regulatory model with institutional self-regulation as the priority, government regulation as the main body, and the public, third parties and other social regulation as the auxiliary.
The prevalence of developmental delay (DD) in children worldwide is still on the rise, and its causes are complex and diverse, causing varying degrees of impact on the development of the sensory nervous system in the brain of children. Sensory integration training is a treatment method that applies sensory stimulation and comprehensive activities. It is currently widely used in children with DD. This therapy can effectively improve the development and integration of the sensory system in children with DD. It also enhances the individual’s ability to adapt to external stimuli, promoting their development in language, motor, and cognitive functions. This article explores the relevant mechanisms of sensory integration training and DD, as well as the current status and effects of its application in DD children, in order to promote the development and progress of related research fields.
Objective To explore the mental health status and influencing factors of clinical medical students pursuing a professional master’s degree under the “dual-track integration” training systems. Methods Clinical medical students pursuing a professional master’s degree who underwent residency standardized training in 123 hospitals from different areas of China were selected as the research objects from May 28th to June 4th, 2024, and the mental health and stress were investigated by questionnaire. Results A total of 1195 clinical medical students pursuing a professional master’s degree were included. Symptom Checklist-90 analysis showed that 582 (48.7%) master students had mental health problems. The two-group students (with and without psychological problems) had statistical differences in exercise frequency, sleep quality, extent of staying up late, interpersonal communication, and average number of night shifts per month (P<0.001). The subjective scores of interpersonal pressure, economic pressure, love and marriage pressure, schoolwork pressure, scientific research pressure, clinical work pressure, entering higher education pressure and employment pressure, and the proportion of graduating from 985/211 university of the master students with psychological problems were significantly higher than those of the master students without psychological problems (P<0.001). Logistic regression analysis showed that poor sleep quality [odds ratio (OR)=1.626, 95% confidence interval (CI) (1.085, 2.438), P=0.019], 985/211 university degree [OR=1.448, 95%CI (1.097, 1.910), P=0.009], interpersonal pressure [OR=1.194, 95%CI (1.121, 1.272), P<0.001], love and marriage pressure [OR=1.067, 95%CI (1.014, 1.122), P=0.012] and entering higher education pressure [OR=1.110, 95%CI (1.055, 1.167), P<0.001] were independent risk factors, while the male sex [OR=0.621, 95%CI (0.472, 0.817), P=0.001] were protective factor for psychological problems of these medical students. Conclusions Under the “dual-track integration” training systems, the clinical medical students pursuing a professional master’s degree have a higher prevalence of psychological problems, especially the females and the 985/211 bachelor’s degree scholars. It is important to improve sleep quality, strengthen interpersonal interaction and reduce pressure load to improve the mental health level of these clinical medical students.

Physiological studies reveal that rats rely on multiple spatial cells for spatial navigation and memory. In this paper, we investigated the firing mechanism of spatial cells within the entorhinal-hippocampal structure of the rat brain and proposed a spatial localization model for mobile robot. Its characteristics were as follows: on the basis of the information transmission model from grid cells to place cells, the neural network model of place cells interaction was introduced to obtain the place cell plate with a single-peaked excitatory activity package. Then the solution to the robot’s position was achieved by establishing a transformation relationship between the position of the excitatory activity package on the place cell plate and the robot’s position in the physical environment. In this paper, simulation experiments and physical experiments were designed to verify the model. The experimental results showed that compared with RatSLAM and the model of grid cells to place cells, the positioning performance of the model in this paper was more accurate, and the cumulative error in the long-time path integration process of the robot was also smaller. The research results of this paper lay a foundation for the robot navigation method that mimics the cognitive mechanism of rat brain.

ObjectiveTo briefly describe the specific contents of the “four-dimensional integration” standardized training model for neurology residents and analyze the implementation effects.MethodsSince September 2019, the Standard Training Center for Residents in Department of Neurology, Xuanwu Hospital of Capital Medical University trained residents under “four-dimensional integration” standardized training model, including primary knowledge teaching, basic skill training, clinical thinking training, and student group learning. The effect of the “four-dimensional integration” model was measured by comparing the midterm assessment results after four months of training of the resident trainees in Grade 2019 under the “four-dimensional integration” training mode (n=37) with those of the resident trainees in Grade 2018 under regular training mode (n=32). The midterm assessment was conducted through standardized and objective clinical examinations, including three evaluations (theory, skills, and clinical drills), and the pass rate of tests was evaluated through Fisher’s exact probability method for comparison between training groups.ResultsThere was no significant difference in the pass rate of theoretical assessment (100.0% vs. 96.9%, P=0.464) or the pass rate of Mini-Clinical Evaluation Exercise (100.0% vs. 90.6%, P=0.095) between the two groups. The pass rate of skill assessment in Grade 2019 was significantly higher than that of the students in Grade 2018 (94.6% vs. 71.9%, P=0.018).ConclusionThe “four-dimensional integration” standardized training model for neurology residents and it effect are worthy of recognition, which can provide a reference for medical teaching, especially for the standardized training of resident physicians.
