BACKGROUND:Carboxylesterase 1 and inflammatory factors play a crucial role in regulating lipid metabolism and glucose homeostasis.However,the effects of different exercise intensity interventions on carboxylesterase 1 and inflammatory factors in skeletal muscle of type 2 diabetic rats remain to be revealed. OBJECTIVE:To investigate the effects of different exercise intensity interventions on carboxylesterase 1 and inflammatory factors in skeletal muscle of type 2 diabetic rats. METHODS:Thirty-two 8-week-old male Sprague-Dawley rats were randomly divided into normal control group(n=12)and modeling group(n=20)after 1 week of adaptive feeding.Rat models of type 2 diabetes mellitus were prepared by high-fat diet and single injection of streptozotocin.After successful modeling,the rats were randomly divided into diabetic control group(n=6),moderate-intensity exercise group(n=6)and high-intensity intermittent exercise group(n=6).The latter two groups were subjected to treadmill training at corresponding intensities,once a day,50 minutes each,and 5 days per week.Exercise intervention in each group was carried out for 6 weeks.After the intervention,ELISA was used to detect blood glucose and blood lipids of rats.The morphological changes of skeletal muscle were observed by hematoxylin-eosin staining.The mRNA expression levels of carboxylesterase 1 and inflammatory cytokines were detected by real-time quantitative PCR.The protein expression levels of carboxylesterase 1 and inflammatory cytokines were detected by western blot and immunofluorescence. RESULTS AND CONCLUSION:Compared with the normal control group,fasting blood glucose,triglyceride,low-density lipoprotein cholesterol,insulin resistance index in the diabetic control group were significantly increased(P<0.01),insulin activity was decreased(P<0.05),and the mRNA and protein levels of carboxylesterase 1,never in mitosis gene A related kinase 7(NEK7)and interleukin 18 in skeletal muscle tissue were upregulated(P<0.05).Compared with the diabetic control group,fasting blood glucose,triglyceride,low-density lipoprotein cholesterol,and insulin resistance index in the moderate-intensity exercise group and high-intensity intermittent exercise group were down-regulated(P<0.05),and insulin activity was increased(P<0.05).Moreover,compared with the diabetic control group,the mRNA level of NEK7 and the protein levels of carboxylesterase 1,NEK7 and interleukin 18 in skeletal muscle were decreased in the moderate-intensity exercise group(P<0.05),while the mRNA levels of carboxylesterase 1,NEK7,NOD-like receptor heat protein domain associated protein 3 and interleukin 18 and the protein levels of carboxylesterase 1 and interleukin 18 in skeletal muscle were downregulated in the high-intensity intermittent exercise group(P<0.05).Hematoxylin-eosin staining showed that compared with the diabetic control group,the cavities of myofibers in the moderate-intensity exercise group became smaller,the number of internal cavities was reduced,and the cellular structure tended to be more intact;the myocytes of rats in the high-intensity intermittent exercise group were loosely arranged,with irregular tissue shape and increased cavities in myofibers.To conclude,both moderate-intensity exercise and high-intensity intermittent exercise can reduce blood glucose,lipid,insulin resistance and carboxylesterase 1 levels in type 2 diabetic rats.Moderate-intensity exercise can significantly reduce the expression level of NEK7 protein in skeletal muscle,while high-intensity intermittent exercise can significantly reduce the expression level of interleukin 18 protein in skeletal muscle.In addition,the level of carboxylesterase 1 is closely related to the levels of NEK7 and interleukin 18.

OBJECTIVE To summarize the current situation of pharmaceutical clinic service in our hospital over the past five years, and explore sustainable development strategies for service models of pharmaceutical clinics. METHODS A retrospective analysis was conducted on the consultation records of patients who registered and established files at the pharmaceutical clinic in our hospital from January 2019 to December 2023. Statistical analysis was performed on patients’ general information, medication- related problems, and types of pharmaceutical services provided by pharmacists. RESULTS A total of 963 consultation records were included, among which females aged 20-39 years accounted for the highest proportion (66.04%); obstetrics and gynecology- related consultations accounted for the largest number of cases. Additionally, 80 patients attended follow-up visits at our hospital’s pharmaceutical clinic. A total of 1 029 medication-related issues were resolved, including 538 cases of drug consultations (52.28%), 453 medication recommendations (44.02%), 22 medication restructuring(2.14%), and 16 medication education (1.55%); the most common types of medication-related problems identified were adverse drug events(70.07%). CONCLUSIONS Although the pharmaceutical clinic has achieved recognition from clinicians and patients, challenges such as low awareness among healthcare providers and the public persist. Future efforts should focus on strengthening information technology construction, enhancing pharmacist training, and establishing various forms of outpatient pharmaceutical service models.

ObjectiveTo investigate the awareness and clinical practice of guidelines for the prevention and treatment of chronic hepatitis B (2022 edition) among clinicians. MethodsFrom July 19 to December 31, 2024, a self-designed electronic questionnaire was distributed via the WeChat mini program to collect related data from 1 588 clinicians nationwide, including their awareness and practice based on 18 questions regarding testing and referral, diagnosis and treatment, and follow-up. ResultsAmong all respondents, only 350 clinicians correctly understood all the updated key points of antiviral indications and treatment for special populations in the 2022 edition of guidelines for the prevention and treatment of chronic hepatitis B, with an overall awareness rate of 22.0%. Only 20% — 40% of the patients with positive HBV DNA and an age of >30 years receive antiviral therapy, while 80% — 100% of the patients with positive HBV DNA and a family history of hepatitis B cirrhosis or hepatocellular carcinoma receive antiviral therapy. The median follow-up rates at 1 year, 3 years, and 5 years were 67.5% 57.5% and 47.5%,respectively, showing a trend of gradual reduction, which might be associated with the influencing factors such as insufficient time for follow-up management by clinicians, insufficient awareness of the disease among patients, and poor adherence to follow-up. ConclusionThere is a gap between the awareness and practice of guidelines for the prevention and treatment of chronic hepatitis B (2022 edition) among clinicians. It is recommended to further strengthen training and focus on the whole process of “detection, diagnosis, treatment, and management” for patients with chronic hepatitis B in healthcare institutions, in order to promote the implementation of the guidelines.

ObjectiveFunctional near-infrared spectroscopy (fNIRS), a novel non-invasive technique for monitoring cerebral activity, can be integrated with upper limb rehabilitation robots to facilitate the real-time assessment of neurological rehabilitation outcomes. The rehabilitation robot is designed with 3 training modes: passive, active, and resistance. Among these, the resistance mode has been demonstrated to yield superior rehabilitative outcomes for patients with a certain level of muscle strength. The control modes in the resistance mode can be categorized into dynamic and static control. However, the effects of different control modes in the resistance mode on the motor function of patients with upper limb hemiplegia in stroke remain unclear. Furthermore, the effects of force, an important parameter of different control modes, on the activation of brain regions have rarely been reported. This study investigates the effects of dynamic and static resistance modes under varying resistance levels on cerebral functional alterations during motor rehabilitation in post-stroke patients. MethodsA cohort of 20 stroke patients with upper limb dysfunction was enrolled in the study, completing preparatory adaptive training followed by 3 intensity-level tasks across 2 motor paradigms. The bilateral prefrontal cortices (PFC), bilateral primary motor cortices (M1), bilateral primary somatosensory cortices (S1), and bilateral premotor and supplementary motor cortices (PM) were examined in both the resting and motor training states. The lateralization index (LI), phase locking value (PLV), network metrics were employed to examine cortical activation patterns and topological properties of brain connectivity. ResultsThe data indicated that both dynamic and static modes resulted in significantly greater activation of the contralateral M1 area and the ipsilateral PM area when compared to the resting state. The static patterns demonstrated a more pronounced activation in the contralateral M1 in comparison to the dynamic patterns. The results of brain network analysis revealed significant differences between the dynamic and resting states in the contralateral PFC area and contralateral M1 area (F=4.709, P=0.038), as well as in the contralateral PM area and ipsilateral M1 area (F=4.218, P=0.049). Moreover, the findings indicated a positive correlation between the activation of the M1 region and the increase in force in the dynamic mode, which was reversed in the static mode. ConclusionBoth dynamic and static resistance training modes have been demonstrated to activate the corresponding brain functional regions. Dynamic resistance modes elicit greater oxygen changes and connectivity to the region of interest (ROI) than static resistance modes. Furthermore, the effects of increasing force differ between the two modes. In patients who have suffered a stroke, dynamic modes may have a more pronounced effect on the activation of exercise-related functional brain regions.

Amblyopia is a common visual development disorder and is the main cause of monocular vision impairment in children and adults. Photobiomodulation(PBM), a non-invasive treatment method, has gradually gained attention in the field of ophthalmology. This paper begins with the macroscopic manifestation of light on the animal model of amblyopia. Additionally, it discusses the pathological changes of the amblyopic retina and the human eye's central nervous system, as well as the influence and mechanism of PBM on the visual perception and processing system and its chemical effect on the visual system through dopamine and melatonin. It examines its mechanism of action, current clinical application status, and future development direction in order to provide new ideas and theoretical foundation for amblyopia treatment.

OBJECTIVE To explore the characteristics and influential factors of pharmaceutical clinic service demands, providing evidence for optimizing pharmaceutical service models and facilitating pharmaceutical service models of pharmacist role transformation. METHODS A cross-sectional survey design was adopted, and 410 outpatient participants were selected from Fudan University Shanghai Cancer Center through convenience sampling for questionnaire administration from February to May 2025. Kano model was applied to analyze the demand attributes of 25 pharmaceutical services, while questionnaires were used to assess patients’ awareness and demand status. Subgroup analyses were conducted based on key demographic variables such as gender, age, educational attainment, and economic burdens, to SACA- systematically examine the differences in Kano attribute classification among patients in each subgroup. RESULTS The awareness rate of pharmaceutical outpatient services among patients was only 14.63%, yet those who were aware demonstrated a significantly higher demand rate for such services compared to those who were unaware (P<0.001). The demand for pharmaceutical clinic services exhibited a hierarchical characteristic: twelve items were identified as attractive attributes (e. g., providing suggestions for more affordable treatment options, offering online consultation services, etc.), five items as expected attributes (e.g., having a good attitude and being able to patiently answer your questions, etc.), three items as must-have attributes (e.g., providing guidance on medication dosage and usage, providing guidance on medication precautions, etc.), five items as indifferent attributes (e.g., providing treatment plan recommendations based on the patient’s condition). There were zero items classified as reverse attribute. Subgroup analysis revealed that female patients showed greater concern for “neat and clean attire of medical staff” than male patients (P<0.001); patients under 60 years of age demonstrated stronger demand for “providing treatment plan recommendations based on patients’ conditions” compared to patients aged 60 or above (P=0.016); those with below high school education placed greater emphasis on “providing guidance on medication precautions” compared to those with a high school education or above (P=0.011); patients with lower economic burdens exhibited stronger preferences for “neat and clean attire of medical staff ” (P=0.002). CONCLUSIONS The public awareness rate of pharmaceutical clinic services is considerably low; however, those who are aware of such services demonstrate significantly higher demand. The medication safety-related services and convenience-oriented demands should be prioritized in the development of pharmaceutical clinics. Moreover, the study also revealed that factors such as gender, age, educational level, and economic burdens exert significant influences on patients’ service demands.
