Objective: To investigate the association of physical activity and screen time with overweight and obesity among children and adolescents with special needs in Tianjin, so as to provide scientific evidence for childhood obesity prevention and intervention measures in the population. Methods: From January 2022 to June 2024, 296 children and adolescents with intellectual disabilities and autism spectrum disorders aged 2-18 years were recruited from special education schools and institutions in Tianjin. Height and weight were measured, and a standardized questionnaire was used to assess physical activity and screen time. Binary Logistic regression analysis was carried out to investigate the association of physical activity and screen time with overweight and obesity. Results: The prevalence of overweight and obesity among children and adolescents with special needs in Tianjin were 17.2% and 21.6%, respectively, and the combined prevalence of overweight and obesity was 38.9%. The median of moderatetovigorous physical activity (MVPA) time was 0.20 h/d, and physical activity sufficiency rate was 7.8%. The median of screen time was 1.79 h/d, and the screen time compliance rate was 68.2%. The binary Logistic regression results showed that lower levels of MVPA time and increased screen time were associated with a higher risk of overweight and obesity among children and adolescents with special needs [OR(95%CI)=1.80(1.06-3.07), 2.40(1.42-4.07),P<0.05]. Conclusions Insufficient physical activity and excessive screen time are associated with an increased risk of overweight and obesity among children and adolescents with special needs. Therefore, comprehensive intervention measures should be implemented as early as possible to prevent and reduce the incidence of overweight and obesity in this population.

Objective To improve the efficiency and accuracy of videonystagmography calibration test results while enabling effective recognition of saccadic undershoot waveform by developing a dual-stream architecture-based deep learning model. Methods A vestibular function calibration test recognition model with cross-modal feature fusion was constructed by integrating vision transformer (ViT) and a modified ConvNeXt convolutional network. The model utilized trajectory pictures and spatial distribution maps as inputs, employed a multi-task learning framework to classify calibration data, and to directly evaluate undershoot waveform. Results The model showed outstanding performance in assessing calibration compliance. The accuracy, sensitivity, specificity of the model in left side, middle, and right side were all greater than 90%, and AUC values were all greater than 0.99, with 97.66% of optimal accuracy (middle), 98.98% of optimal sensitivity (middle), 96.87% of optimal specificity (right side), and 0.997 of AUC (right side). The model also showed promising performance in undershoot waveform recognition with 87.50% of accuracy, 89.66% of sensitivity, 85.71% of specificity, 86.67% of F1 score, and 0.931 of AUC. Conclusions The proposed method not only significantly enhances the efficiency and accuracy of calibration test results, but also provides a novel solution for undershoot waveform recognition.

ObjectiveTo explore the sequential effects of hypoxic exercising on miR-27/PPARγ and lipid metabolism target gene and protein expression levels in the obesity rats’ liver. Methods13-week-old male diet-induced obesity rats were randomly divided into three groups (n＝10): normal oxygen concentration quiet group (N), hypoxia quiet group (H), hypoxic exercise group (HE). Exercise training on the horizontal animal treadmill for 1 h/d, 5 d/week for a total of 4 week, and the intensity of horizontal treadmill training was 20 m/min (hypoxic concentration was 13.6%). Comparison of the weights of perirenal fat and epididymal fat in rats across different groups and calculation of Lee’s index based on body weight and body length of rats in each group were done. And the serum concentrations of total cholesterol (TC), triglyceride (TG), low density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C) levels were detected. RT-PCR and Western Blot were used to detect the levels of miR-27, PPARγ, CYP7A1 and CD36. ResultsHypoxic exercise decreased the expression levels of miR-27 in the obese rats’ liver, however, the expression level of PPARγ was gradually increased. The expression levels of miR-27 in HE group were significantly lower than N group (P<0.05). The expression levels of PPARγ mRNA in N group were significantly lower than H group (P<0.05), especially lower than HE group (P<0.01). The protein expression of PPARγ protein in N group was significantly lower than that other groups (P<0.01). The expression of lipid metabolism-related genes and proteins increased in the obese rats’ liver. The expression of CYP7A1 mRNA in N group was significantly lower than H group (P<0.05), especially lower than HE group (P<0.01). The expression of CYP7A1 protein in the obese rats’ liver in N group was extremely lower than H group and HE group (P<0.01). The protein expression of CD36 in N group was significantly lower than that in HE group (P<0.05). Hypoxia exercise improved the related physiological and biochemical indexes of lipid metabolism disorder. The perirenal fat weight of obese rats in HE group was extremely lower than N group and H group (P<0.01), and the perirenal fat weight in N group was significantly higher than H group (P<0.05). The epididymal fat weight in N group was significantly higher than H group (P<0.05), and extremely higher than HE group (P<0.01). The Lee’s index in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of TC in obese rats in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of TG in HE group was extremely lower than N group and H group (P<0.01). The serum concentration of LDL-C in N group was extremely higher than HE group (P<0.01). The serum concentration of HDL-C in N group was extremely lower than H group (P<0.01). ConclusionHypoxia and hypoxia exercise may negatively regulate the levels of PPARγ by inhibiting miR-27 in the obese rats’ liver, thereby affecting the expression of downstream target genes CYP7A1 and CD36, and promoting cholesterol, fatty acid oxidation and HDL-C transport in the liver, and ultimately the lipid levels in obese rats were improved. The effect of hypoxia exercise on improving blood lipid is better than simple hypoxia intervention.

As the important source of bone cells, osteoblasts are involved in bone formation and repair, and play a key role in maintaining bone balance. If the osteogenic differentiation process in vivo is disrupted, a variety of bone-related diseases may occur. Natural products, which have a wide range of sources, a wide variety of physiological activities, and few toxic side-effects, have been found in recent years to be able to regulate osteoblast differentiation. Based on the sources of natural products, this paper reviews the intervention of natural products from plant, animal and microbial sources on osteogenic differentiation, aiming to provide a theoretical basis for natural products in the treatment of bone diseases.

Tripterygium wilfordii polyglycosides are one of the most commonly used Tripterygium wilfordii preparations， which have anti-inflammatory and immune-regulating effects. Their unique therapeutic effect on some autoimmune diseases and kidney diseases is almost irreplaceable by other similar drugs， but the possible reproductive damage is the bottleneck that hinders their clinical application. In clinical use， female patients often suffer from menstrual cycle disorders， decreased menstrual flow， even amenorrhea， infertility， and other symptoms， and the main toxic mechanism lies in damaging the reproductive and endocrine functions of the ovary and inhibiting the growth and development of follicles. Therefore， it is particularly necessary to understand the toxic and side effects of Tripterygium wilfordii polyglycosides on female reproduction and master the detoxification methods during clinical use. However， there is no clear solution to these problems. According to the theory of traditional Chinese medicine， "kidney governs reproduction"， and the relationship between kidney Yin， kidney essence， and female ovum is close. Therefore， by considering that the damage to the reproductive system caused by Tripterygium wilfordii polyglycosides belongs to the category of kidney deficiency， Yin damage， and essence deficiency， the "strengthening kidney Yin" method is proposed. It points out that the reproductive toxicity damage of Tripterygium wilfordii polyglycosides on the female can be effectively alleviated by tonifying kidney and Yin essence in clinical use. The relevant research on traditional Chinese medicine， classical prescription， test prescription， and acupuncture is summarized to verify the necessity of the "strengthening kidney Yin" method， so as to provide a theoretical basis for the safe and rational clinical use of Tripterygium wilfordii.

Euglycemic diabetic ketoacidosis(euDKA)is a rare acute metabolic disorder syndrome,its characteristics include metabolic acidosis with a high anion gap,positive ketones in blood or urine,and blood glucose＜13.9 mmol/L.Due to low blood sugar level,euDKA is easy to be missed or delayed treatment in clinical work,resulting in serious consequences.In recent years,many cases of euDKA have been reported,but its inducements and pathogenesis are not fully understood.This article reviews the common inducements and pathogenesis of euDKA.

ObjectiveTranscription factor NFE2 was observed abnormal expression in myeloproliferative neoplasm (MPN) patients. However, how NFE2 is transcriptionally regulated remains ambiguous. This study aims to explore the elements and molecular mechanisms involved in the transcriptional regulation of NFE2. MethodsActive enhancers were predicted by public NGS data and conformed experimentally via dual luciferase reporter assay. After that, PRO-seq and GRO-seq data was used to detect enhancer RNAs transcribed from these enhancers. RACE was utilized to clone the full length enhancer RNA (eRNA) transcripts, and RT-qPCR was used to measure their expression in different leukemia cell lines as well as the transcript levels during induced differentiation. Finally, to investigate the molecular function of the eRNA, overexpression and knockdown of the eRNA via lentivirus system was performed in K562 cells. ResultsWe identified three enhancers regulating NFE2 transcription, which located at -3.6k, -6.2k and +6.3k from NFE2 transcription start site (TSS) respectively. At the -3.6k enhancer, we cloned an eRNA transcript and characterized that as a lncRNA which was expressed and located in the nucleus in three types of leukemia cell lines. When this lncRNA was overexpressed, expression of NFE2 was upregulated and decreases of K562 cell proliferation and migration ability were observed. While knocking down of this lncRNA, the level of NFE2 decreases correspondingly and the proliferation ability of K562 cells increases accordingly. ConclusionWe identified an enhancer lncRNA that regulates NFE2 transcription positively and suppresses K562 cell proliferation.

Morita therapy has been bom for more than 100 years.Inpatient Morita therapy is highly oper-able and easy to master.It can improve many refractory neuroses through four-stage treatment.But more neuroses are treated in outpatient clinics,and Morita therapy cannot be used in hospitalized patients.Therefore,the formula-tion of expert opinions on outpatient operations is particularly important.This paper is based on domestic and for-eign references,and after many discussions by domestic Morita therapy experts,and then drew up the first version of the expert opinions on operation of outpatient Morita therapy.Meanwhile the operation rule of Morita therapy in three stages of outpatient treatment was formulated:in the etiological analysis stage,under the theoretical guidance of Morita therapy,analyze the pathogenic factors,to improve treatment compliance and reduce resistance;during the operating stage,guide patients to engage in constructive and meaningful actions,realizing the achievement of letting nature take its course principle;in the cultivating character and enriching life stage,pay attention to positive infor-mation,expanding the scope and content of actions,improving the ability to adapt to complex life,and preventing recurrence caused by insufficient abilities.It will lay a foundation for the promotion of Morita therapy in domestic outpatient clinics,so that more patients with neurosis and other psychological diseases could receive characteristic Morita therapy treatment in outpatient clinics.

BACKGROUND:Electrospun porous nanofiber exhibits excellent properties and designability.It is an effective way to control the release of traditional Chinese medicine and improve the bioavailability to design an advanced drug delivery system,which has a broad application prospect. OBJECTIVE:To review the construction methods of the electrospinning drug delivery system of traditional Chinese medicine and its related research progress in the medical field. METHODS:The literature search was performed in CNKI,PubMed,and Web of Science databases with the search terms"electrospinning,traditional Chinese medicine,drug carrier,drug delivery system,tissue engineering,dressing"in both English and Chinese for articles published from 2013 to 2023.Finally,62 articles were included in this review. RESULTS AND CONCLUSION:(1)The key elements of the electrospinning drug delivery system of Chinese medicine preparation are substrate material,traditional Chinese medicine composition,and drug loading method.(2)The preparation of the electrospinning drug delivery system of Chinese medicine can be carried out according to the application scenario and therapeutic purpose.Firstly,the types of Chinese medicine are selected,then the polymer matrix and solution suitable for them are selected,and finally,the fiber structure is designed according to the drug release requirements and the appropriate drug loading method is adopted.(3)At present,the medicinal agents used are mainly plant Chinese medicine,and there is a lack of systematic research on animal and mineral Chinese medicine.(4)Blended drug loading is the most studied and applied drug loading method,and its drug release characteristics and adaptation scenarios are constantly expanded by optimizing the physicochemical properties of the solution and selecting the diversity of loaded substances.Multilayer fibers with different compositions and properties can be prepared by coaxial,multi-axis,and sequential electrospinning methods,which have broad development prospects.(5)The early application of the electrospinning drug delivery system of Chinese medicine focused on medical dressings according to the antibacterial and hemostatic functions.In recent years,it has been studied in the field of tissue engineering because some components of traditional Chinese medicine can promote cell adhesion,proliferation,and differentiation.(6)At present,the research mainly focuses on the characterization and optimization of loading materials,processes,physicochemical properties,and biological properties,but the research on the mechanism is less.Its clinical application has not been widespread;the adverse reactions in vivo and the interaction between its degradation behavior and drug release behavior are still unknown.(7)Future studies need to consider:We should expand the application of Chinese medicine by improving the physicochemical properties and increasing the purification of Chinese medicine extracts.We need to comprehensively study the therapeutic effects and application mechanisms of Chinese medicine,and clarify the interaction of degradation behavior and drug release behavior,to achieve a more perfect combination and application of Chinese medicine and electrospinning nanofibers under a more accurate mechanism.

BACKGROUND:Numerous clinical studies have suggested a close relationship between obesity and osteoporosis,but whether there is a genetic causal effect between obesity and osteoporosis remains unclear. OBJECTIVE:To explore the association between obesity and osteoporosis using summary data from a large-scale genome-wide association study(GWAS)through Mendelian randomization analysis. METHODS:Obesity data were derived from summary statistics of the Genetic Investigation of Anthropometric Traits(GIANT)and the UK Biobank(UKBB).Osteoporosis data were obtained from the Genetic Factors for Osteoporosis(GeFOS)consortium,including two bone density phenotypes:total body bone mineral density(BMD)and heel BMD.The inverse variance-weighted method was the primary analysis,with the Mendelian randomization method based on Egger regression(MR-Egger)and weighted median method as supplementary approaches to calculate the causal association between genetic variations related to obesity and osteoporosis.Sensitivity analyses were conducted to validate the reliability of the results.Heterogeneity was assessed using Cochran's Q test.Horizontal pleiotropy was assessed through the MR-Egger intercept test.Leave-one-out analysis was performed to evaluate the potential influence of single nucleotide polymorphisms on the combined inverse variance-weighted estimates. RESULTS AND CONCLUSION:(1)Impact of obesity on osteoporosis:In addition to body mass index and forearm BMD,body mass index,waist-to-hip ratio,body mass index-adjusted waist-to-hip ratio,and whole-body body mass index,heel BMD,forearm BMD,lumbar spine BMD,and femoral neck BMD were causally related to each other.Further Meta-analysis revealed that obesity increased the risk of BMD(odds ratio=1.07,95%confidence interval:1.03-1.12,P<0.01).(2)Impact of osteoporosis on obesity:Apart from arm BMD and lumbar spine BMD as exposure factors showing causal relationships with obesity,other datasets indicated no causal effect between total body BMD,heel BMD,femoral neck BMD,and obesity.Additional meta-analysis demonstrated that BMD did not increase the risk of obesity(odds rate=0.99,95%confidence interval:0.98-1.01,P<0.01).There is a causal relationship between obesity and osteoporosis,suggesting that obesity may be a risk factor for osteoporosis.However,no causal association is found between osteoporosis and obesity.
