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 investigate the relationship between cognitive impairment and sleep parameters in acute ischemic stroke patients with obstructive sleep apnea(OSA).Methods A total of 343 patients with acute ischemic stroke and OSA were selected.The cognitive function was assessed using the simple mental state examination scale(MMSE).Patients were divided into the stroke with OSA and cognitive impairment group(MMSE＜27 points,n=119)and the stroke with OSA without cognitive impairment group(MMSE≥27 points,n=224).General data,TOAST etiological classification and distribution of cerebral infarction lesions were collected.The intelligent sleep monitoring system was used to calculate apnea hypopnea index(AHI)and evaluate OSA.Objective sleep monitoring parameters were collected at night.Sleep monitoring was conducted within 24 h of admission and continuous monitoring for≥3 nights.Continuous monitoring duration≥7 h every night to obtain night sleep structure parameters.Multifactor Logistics regression was used to analyze the relationship between cognitive impairment and sleep parameters in stroke patients with OSA.Results Compared with the stroke with OSA without cognitive impairment group,the proportion of age,diabetes history and HHcy history,the proportion of patients with infarct lesions located in frontal,temporal,parietal,occipital,thalamus,basal ganglia,brainstem and hemioval center increased in the stroke with OSA and cognitive impairment group,and the number of years of education decreased,the number of waking times,the proportion of light sleep and AHI increased,the nighttime sleep efficiency and deep sleep period decreased(P＜0.05).Logistics regression analysis showed that after controlling for years of education,age and other interference factors,nighttime sleep efficiency and AHI were strongly associated with cognitive impairment in acute ischemic stroke patients with OSA(P＜0.05).The increased nighttime sleep efficiency was protective factor for cognitive impairment,and increased AHI was risk factor for cognitive impairment.Conclusion Cognitive impairment in acute ischemic stroke patients with OSA is closely related to sleep parameters,in which the increased sleep efficiency at night is a protective factor for cognitive impairment,and the increased AHI is a risk factor.

Over-expression of glutathione S-transferase(GST)can promote Cisplatin resistance in hepatocellular carcinoma(HCC)treatment.Hence,inhibiting GST is an attractive strategy to improve Cisplatin sensi-tivity in HCC therapy.Although several synthesized GST inhibitors have been developed,the side effects and narrow spectrum for anticancer seriously limit their clinical application.Considering the abundance of natural compounds with anticancer activity,this study developed a rapid fluorescence technique to screen"green"natural GST inhibitors with high specificity.The fluorescence assay demonstrated that schisanlactone B(hereafter abbreviated as C1)isolated from Xue tong significantly down-regulated GST levels in Cisplatin-resistant HCC cells in vitro and in vivo.Importantly,C1 can selectively kill HCC cells from normal liver cells,effectively improving the therapeutic effect of Cisplatin on HCC mice by down-regulating GST expression.Considering the high GST levels in HCC patients,this compound demon-strated the high potential for sensitizing HCC therapy in clinical practice by down-regulating GST levels.

OBJECTIVE: We aimed to understand the willingness and barriers to the acceptance of tuberculosis (TB) preventive treatment (TPT) among people with latent TB infection (LTBI) in China. METHODS: A multicenter cross-sectional study was conducted from May 18, 2023 to December 31, 2023 across 10 counties in China. According to a national technical guide, we included healthcare workers, students, teachers, and others occupations aged 15-65 years as our research participants. RESULTS: Overall, 17.0% (183/1,077) of participants accepted TPT. There were statistically significant differences in the acceptance rate of TPT among different sexes, ages, educational levels, and occupations ( P < 0.05). The main barriers to TPT acceptance were misconceptions that it had uncertain effects on prevention (57.8%, 517/894), and concerns about side effects (32.7%, 292/894). CONCLUSION An enhanced and comprehensive understanding of LTBI and TPT among people with LTBI is vital to further expand TPT in China. Moreover, targeted policies need to be developed to address barriers faced by different groups of people.

Objective:To explore the effect of moderate intensity physical exercise on depression, anxiety and cognitive function of schizophrenic patients and its possible biochemical mechanism.Methods:Totally 148 patients with schizophrenia who were hospitalized in hospital from March 2019 to March 2021 were randomly divided into control group ( n=75) and exercise group ( n=73). The patients of the two groups were given drug treatment and routine exercise according to clinical practice, and the patients in exercise group were given additional medium-intensity physical exercise.Self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were used to evaluate the poor mental state of the subjects.The verbal fluency task(VFT), digital span test(DST), trail making test-A(TMT-A) and the positive and negative symptom scale (PANSS) were used to evaluate cognitive function.The levels of endocannabinoids (eCBs) receptors were detected by high performance liquid chromatography, and the levels of monoamine neurotransmitters and eCBs in the patients' serum were determined by enzyme-linked immunosorbent assay (ELISA). SPSS 19.0 software was used for statistical analysis.The measurement data between the two groups were compared by t-test and the counting data between the two groups were compared by χ2 test. Results:(1) After effective intervention, the scores of SAS, SDS, TMT-A and PANSS of the two groups were significantly lower than those before intervention, and the difference before and after intervention between the two groups was statistically significant( t=6.00, 6.52, 25.79, 17.03, all P<0.01). The scores of SAS, SDS, TMT-A and PANSS after intervention in the exercise group were significantly lower than those in the control group( t=4.66, 20.88, 6.61, 8.95; all P<0.01). The number of VFT and DST in the two groups after intervention were significantly higher than those before intervention, and the differences before and after intervention between the two groups were statistically significant( t=13.78, 22.76, both P<0.01). After effective intervention, the number of VFT and DST in exercise group were significantly higher than those in the control group( t=5.02, 5.15, both P<0.01). (2) After effective intervention, the contents of monoamine neurotransmitters and eCBs in serum of the two groups were significantly higher than those before intervention, and HVA level ((63.68±6.99) pg/mL), MHPG level ((175.90±16.22) pg/mL), 5-HIAA level ((29.94±4.19) pg/mL) and CBR1 level ((6.70±1.40)μg/L), 2-AG level ((61.90±5.73)pmol/g) and AEA level ((76.48±6.59) pmol/g) in exercise group were significantly higher than those in the control group ((52.97±5.37)pg/mL, (138.50±11.52)pg/mL, (23.87±3.15)pg/mL, (5.71±1.29)μg/L, (52.13±5.14)pmol/g, (67.66±5.88)pmol/g)( t=10.43, 16.21, 10.91, 8.65, all P<0.01). Conclusion:Moderate intensity physical exercise can significantly improve their depression, anxiety and cognitive function, which may be related to regulating the levels of ECBS and their receptors in patients with chronic schizophrenia to increase monoamine neurotransmitters.
