Objective:To investigate the clinical effect of near-infrared autofluorescence (NIRAF) imaging combined with nano-carbon in the identification of parathyroid gland.Methods:A total of 80 patients with thyroid cancer requiring bilateral thyroidectomy plus single/bilateral central area lymphatic dissection were prospectively enrolled in the Department of Thyroid and Breast Surgery of the Shenzhen Third People′s Hospital from January 2020 to June 2023. Two groups were divided in order of time of admission. In the combined group (40 cases), the parathyroid glands were identified by NIRAF+ nano-carbon negative imaging. The nano-carbon group (40 cases) was negatively developed with nano-carbon alone. The detection rate and accuracy of parathyroid gland and the changes of parathyroid hormone (1 d and 6 months after operation) were compared between the two groups.Results:There was no significant difference in the detection rate of parathyroid glands between the two groups ( P=0.65), and the accuracy rate in the combined group was higher than that in the nano-carbon group, the difference was statistically significant (χ 2=8.79, P=0.003). The level of parathyroid hormone in the combined group was higher than that in the nano-carbon group 1 day after surgery, and the difference was statistically significant ( Z=-1.19, P=0.03). There was no significant difference in parathyroid hormone levels between the two groups 6 months after operation ( P=0.18). Conclusions:NIRAF imaging combined with nano-carbon negative imaging can improve the accuracy of intraoperative parathyroid identification, and may reduce the incidence of temporary postoperative hypoparathyroidism.

Objective To investigate the inhibitory effect of running combined with chitosan on high-fat diet(HFD)induced obesity in rats through the expression of fatty acid transporter 4(FATP4)and Toll like receptor 4(TLR4)and its mechanism.Methods 50 male Wistar rats were randomly divided into normal control(NC)group,HFD group,chitosan(Chi)group,running exercise(Run)and chitosan+running exercise(Chi+Run)group,with 10 rats in each group.The levels of serum total cholesterol(TC),triglyceride(TG),high-density lipoprotein cholesterol(HDL-C),low-density lipoprotein cholesterol(LDL-C),very low density lipoprotein cholesterol(VLDL-C),alanine aminotransferase(ALT)and aspartate aminotransferase(AST)were detected.ELISA was used to detect serum TNF-α,IL-6,APN,Ghrelin,Leptin(LP),and Ins levels.Western blot was used to test the expression of FATP4 and TLR4 proteins in liver and adipose tissue,and HE staining was used to evaluate liver and adipose tissue pathology.Results Compared with the HFD group,the Chi,Run,and Chi+Run groups showed an increase in HDL-C,serum APN,and Ghrelin(P<0.05),as well as an decreased in body weight,fat mass,obesity index,TC,TG,LDL-C,VLDL-C,ALT,AST,TNF-α,IL-6,LP,Ins,FATP4 protein expression,TLR4 protein expression,adipocyte size and quantity in liver and adipose tissue(P<0.05).The HDL-C was higher in Chi+Run group than in Chi and Run groups(P<0.05),and the final weight,LDL-C,TG,AST,IL-6,the expression of FATP4 protein,TLR4 protein,and adipocyte size in the liver and adipose tissue were lower in Chi+Run group than in Chi and Run groups(P<0.05).Conclusions The inhibitory effect of running combined with Chi on HFD induced obesity was superior to that of running or Chi alone,and its mechanism may be related to the downregulation of FATP4 and TLR4.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Objective:To analyze the clinical characteristics of the Chikungunya fever outbreak in Shunde District, Foshan City, Guangdong Province in July 2025 and the risk factors associated with delayed viral RNA clearance.Methods:A total of 562 patients with Chikungunya fever admitted to three designated hospitals in Shunde District from July 10 to 30, 2025 were enrolled. Demographic data, clinical manifestations, and laboratory findings were collected. Patients were categorized into four age groups including minors (<18 years), young adults (18 to 39 years), middle-aged adults (40 to 64 years) and elderly adults (≥65 years). The differences of clinical characteristics among these age groups were analyzed. Intergroup comparisons were performed using chi-square test, one-way analysis of variance, or Kruskal-Wallis H test. Pairwise comparisons between groups were conducted using the Bonferroni or Games-Howell or Dunn method. Binary logistic regression was employed to analyze risk factors associated with delayed viral RNA clearance (>7 days). Results:The mean age of the 562 enrolled Chikungunya fever patients was (44.8±21.3) years. Fever, arthralgia and rash were the three core symptoms, with incidence rates of 87.5% (492/562), 88.4%(497/562) and 69.6%(391/562), respectively. At discharge, only 54.1%(304/562) of patients achieved complete symptom resolution, while 26.5%(149/562) still had arthralgia and 36.1%(203/562) had residual rash. Significant differences were observed among age groups in the incidence of fever ( χ2=9.43, P=0.024), peak body temperature ( F=6.54, P<0.001), incidence of arthralgia ( χ2=26.89, P<0.001), duration of arthralgia ( F=12.68, P=0.001), incidence of rash ( χ2=68.99, P<0.001), rate of residual rash at discharge ( χ2=32.37, P<0.001), lymphocyte count ( F=12.94, P<0.001), platelet count ( F=14.95, P<0.001), and C-reactive protein levels (CRP) ( H=94.18, P<0.001). Further pairwise comparisons revealed that compared to the middle-aged and elderly groups, the minor group had a higher incidence of fever and a lower incidence of arthralgia, and the duration of arthralgia was shorter than the elderly group (all P<0.008 3). Compared with the other three groups, the elderly group had lower incidence and residual rate of rash, and lower platelet counts (all P<0.008 3), and higher levels of CRP (all P<0.05). The elderly group had lower lymphocyte counts compared to the minor and young adult groups (both P<0.05). Significant differences were found among age groups in the time to viral RNA clearance ( F=5.77, P=0.003) and length of hospital stay ( F=11.64, P<0.001), with the elderly group having significantly longer duration for both compared to the other three groups (all P<0.05). Multivariate analysis showed that advanced age (odds ratio ( OR)=1.049, 95% confidence interval ( CI) 1.015 to 1.083), longer duration of fever ( OR=1.529, 95% CI 1.086 to 2.155) and longer duration of arthralgia ( OR=1.927, 95% CI 1.318 to 2.817) were independent risk factors for delayed viral RNA clearance (all P<0.05). Conclusions:Patients with Chikungunya fever in Shunde District primarily present with fever, arthralgia and rash. The incidence and characteristics of these three core symptoms show age-related variations. Elderly patients and those with longer durations of fever or arthralgia are more likely to experience delayed viral clearance.

Obstructive sleep apnea (OSA) is a global public health concern characterized by repeated upper airway collapse during sleep. Research indicates that OSA is a risk factor for the development of various diseases, including cardiovascular disease, metabolic disorders, respiratory diseases, neurodegenerative diseases, and cancer. Exosomes, extracellular vesicles released by most cell types, play a key role in intercellular communication by transporting their contents-such as microRNA, messenger RNA, DNA, proteins, and lipids-to target cells. Intermittent hypoxia associated with OSA alters circulating exosomes and promotes a range of cellular structural and functional disturbances involved in the pathogenesis of OSA-related diseases. This review discusses the potential roles of exosomes and exosome-derived molecules in the onset and progression of OSA-associated diseases, explores the possible underlying mechanisms, and highlights novel strategies for developing exosome-based therapies for these conditions.

ObjectiveTo analyze the on-site technical evaluation results of the provincial-level health enterprises in Shandong Province. Methods A total of 88 provincial-level health enterprises in Shandong Province in 2021 were selected as the research subjects using the convenient sampling method. The scores of on-site technical assessments were analyzed. Results The total score of on-site technical evaluations for the 88 provincial health enterprises was (942.1±21.8) points. The scores for the first-level indicators, including management system, health environment, health management and services, and health culture, were (193.7±4.7), (191.6±5.2), (414.4±16.4), and (142.3±6.7) points, respectively. The score for health culture in large-sized enterprises was higher than that in medium-sized and below enterprises (P<0.05). State-owned enterprises had higher total scores than private enterprises and joint-stock enterprises (both P<0.05). The score for health management and services in the mining industry was higher than that in the manufacturing industry (P<0.05). Enterprises with high total investment in health promotion had higher scores for health culture than those with low investment (P<0.05). There were no significant differences in the scores for indicators of management system and health environment among enterprises of different sizes, natures, industries, and total investments in health promotion (all P>0.05). Conclusion The overall score of these 88 enterprises was higher than the standard for provincial health enterprises. Except for management systems and general environment, there were some differences in the scores for health management and services, and health culture assessments among enterprises of different sizes, natures, industries, and total investments in health promotion.
