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 evaluate the efficacy of a cetyl alcohol-containing moisturizing cream (referred to as the emollient) in improving clinical symptoms and preventing disease relapse during the remission phase of mild to moderate infantile atopic dermatitis (AD).Methods:A single-center, investigator-blinded, randomized controlled clinical trial was conducted from February 2022 to October 2023. Sixty participants aged >28 days to ≤2 years with mild to moderate AD (Investigator′s Global Assessment (IGA) score 2 or 3) and controlled disease (IGA 0 or 1) were enrolled. Participants were randomized 1∶1 to either the experimental group (topical emollient applied twice daily combined with a moisturizing cleanser for daily bathing) or the control group (moisturizing cleanser alone). Assessments at weeks 2, 4, 8, and 12 included AD relapse rates, clinical severity scores (IGA and Eczema Area and Severity Index (EASI)), and adverse events.Results:Fifty-six participants were included in the full analysis set. The median time to relapse was 12.0 (6.0-72.0) days in the experimental group versus 8.5 (3.0-19.0) days in the control group (log-rank test: χ2=3.079, P=0.213). Relapse rates were 80.77% (21/26) in the experimental group and 95.83% (23/24) in the control group ( χ2=2.682, P=0.101). The experimental group showed significantly lower IGA scores at weeks 2 and 12 ( P<0.05) and lower EASI scores at weeks 4 and 12 ( P<0.05). Adverse event rates were 8.0% (2/25) and 7.7% (2/26) in the experimental and control groups, respectively ( χ2=0.002, P>0.05) Conclusion:The combination of the cetyl alcohol- containing moisturizing cream and moisturizing cleanser during AD remission may improve clinical symptoms and modestly delay relapse, with a low incidence of adverse events.

Objective To investigate the changes of serum metabolites in patients with occupational chronic lead poisoning using non-targeted metabolomics, and to screen differential metabolic pathways. Methods A total of 14 patients with occupational chronic lead poisoning were selected as the poisoning group, and 14 healthy people without occupational hazard exposure history were selected as the control group using the judgment sampling method. Serum of the individuals from the two groups was collected. Non-targeted metabolomics technology based on ultra high performance liquid chromatography-tandem mass spectrometry was used to detect serum metabolite levels in the two groups. Differential metabolites (DMs) were screened by the principal component analysis, partial least squares discriminant analysis and orthogonal partial least squares discriminant analysis, and related metabolic pathways were explored. Results The blood lead level in the poisoning group was higher than that in the control group (median: 359.59 vs 5.04 μg/L, P<0.01). There were significant differences in serum metabolites between the poisoning group and control group. After the combination of results from the positive and negative ion patterns, a total of 89 DMs were screened in serum of patients in the poisoning group, including 50 upregulated and 39 downregulated metabolites compared with the control group. The serum DMs of poisoning group were mainly enriched in arginine biosynthesis, ABC transporter, purine metabolism, choline metabolism in malignant tumor, glycerophospholipid metabolism and ether lipid metabolism compared with the control group (all P<0.05). Conclusion Abnormal changes of serum metabolic profile occurred in patients with occupational chronic lead poisoning. The metabolic pathways such as arginine biosynthesis, ABC transporter, purine metabolism, choline metabolism, glycerophospholipid metabolism and ether lipid metabolism may be involved in the occurrence and development of lead poisoning.

Central nervous system idiopathic inflammatory demyelinating diseases (CNS-IIDD) is an autoimmune disorder characterized by inflammatory demyelination. The disease follows a course of recurrent attacks and remission, with some cases displaying continuous progression, often resulting in disability. The incidence of CNS-IIDD has been increasing, imposing a substantial burden on both patients′ families and society in recent years. A promising strategy for disease management involves the identification of humoral biomarkers to diagnose CNS-IIDD and predict disease attack and progression. Such biomarkers could aid in identifying individuals at high risk of disability, enabling targeted preventive interventions. This study summarizes advancements in the identification of humoral biomarkers and their potential for predicting disease activity and progression to offer novel insights into the management of CNS-IIDD.

Objective To explore the potential categories of self-regulatory fatigue among maintenance hemodialysis patients and their relationships with self-management. Methods A total of 502 maintenance hemodialysis patients in Lanzhou were surveyed using a general information questionnaire, a Self-Regulatory Fatigue Scale, and a Self-Management Scale for Hemodialysis Patients. Potential profile analysis was conducted on self-regulatory fatigue, and its relationship with self-management was explored. Results Based on their self-regulatory fatigue status, maintenance hemodialysis patients could be categorized into four potential groups: low self-regulatory fatigue group (5.0%), moderate self-regulatory fatigue group (49.2%), high self-regulatory fatigue group (13.9%), and high cognitive regulatory fatiguegroup (31.9%). Gender, education level, and monthly per capita family income were identified as influencing factors for the potential categories of self-regulatory fatigue. Significant differences were observed in the total self-management scores among patients belonging to different potential categories of self-regulatory fatigue (F=50.617, P < 0.001). Conclusion Maintenance hemodialysis patients can be classified into four potential categories of self-regulatory fatigue, with patients in the low self-regulatory fatigue group demonstrating higher levels of self-management. Reducing the level of self-regulatory fatigue can contribute to enhancing patients'self-management capabilities.

OBJECTIVE To compare anti-ischemic stroke （IS） effect of different extraction parts from Gastrodia elata， and to provide reference for screening the anti-IS effective parts of G. elata. METHODS G. elata was extracted and separated by ethanol reflux extraction and ethyl acetate extraction. The rat model of diffuse cerebral thrombosis was induced by internal carotid artery injection of arachidonic acid （AA）； the anti-IS effect of G. elata powder， ethanol extract of G. elata， residue of ethanol extract of G. elata， ethyl acetate extract of G. elata， residue of ethyl acetate extract of G. elata， gastrodin and aspirin （positive control drug） were investigated with the content of Evans blue （EB） in the ischemic brain tissue as index. RESULTS Compared with model group， aspirin， ethanol extract of G. elata and ethyl acetate extract of G. elata could significantly decrease the content of EB in the ischemic brain tissue of model rats （P＜0.05）. G. elata powder had the tendency to reduce the content of EB in the ischemic brain tissue of model rats， without statistical significance （P＞0.05）. The residue of ethanol extract of G. elata， residue of ethyl acetate extract of G. elata and gastrodin had little effect on the content of EB in the ischemic brain tissue of model rats. CONCLUSIONS Both ethanol extract of G. elata and ethyl acetate extract of G. elata have anti-IS effects， which are stronger than that of G. elata powder.

Objective:To evaluate the efficacy and tolerability of crisaborole 2% ointment in the treatment of childhood atopic dermatitis (AD) at the early stage, and to compare the efficacy of every-other-day (Qod) regimen versus twice-a-week (Biw) regimen against recurrence in the remission stage of AD.Methods:A multicenter, randomized, open-label clinical trial was conducted. Totally, 150 children with mild to moderate AD aged 2 - < 18 years were enrolled from 6 hospitals (including Beijing Children′s Hospital, Capital Medical University, etc), and randomly divided into the Qod group (76 cases) and the Biw group (74 cases). In the acute stage of AD, both groups were treated with topical crisaborole 2% ointment on skin lesions twice a day for 2 - 4 weeks, as well as with emollients throughout the whole body. The improvement of early clinical symptoms was evaluated, and the occurrence of adverse reactions was recorded in the follow up. Once the investigator′s static global assessment (ISGA) scores decreased to 1 point or less, the patient would be enrolled into the remission stage. In the remission stage of AD, patients in the Qod group and Biw group were treated with crisaborole ointment every other day and twice a week respectively; the recurrence rate of AD in the remission stage was evaluated, as well as the severity of skin lesions, itching, life quality, and the occurrence of adverse reactions at weeks 4, 8, and 12. Statistical analysis was carried out with SPSS 23.0 software by using t test for comparisons of normally distributed continuous data between two groups, Mann-Whitney U test for non-normally distributed data, chi-square test for enumeration data, and Kaplan-Meier method for analysis of survival rates. Results:A total of 142 patients were enrolled in the modified intention-to-treat population, including 71 in the Qod group and 71 in the Biw group. In the acute stage of AD, the improvement of itching and skin lesions self-reported by the children or their family members occurred on days 1.9 (1.0, 3.0) and 2.0 (1.0, 4.1) after the application of crisaborole ointment, respectively. At the end of treatment in the acute stage, 89 children (62.7%) achieved ISGA 0/1 and successfully transferred into the remission stage. The follow-up in the remission stage was completed in 83 patients (44 in the Qod group and 39 in the Biw group). In addition, recurrence occurred in 19 (43.2%) and 12 (30.8%) patients in the Qod group and Biw group respectively, and there was no significant difference in the recurrence rate between the two groups ( χ2 = 1.36, P = 0.243) ; the average time to recurrence was 64.25 (95% CI: 53.33 - 75.17) days and 75.78 (95% CI: 65.46 - 86.10) days in the Qod group and Biw group respectively. Among the patients who were in the remission stage and had not yet experienced relapse at weeks 4, 8, and 12, there were no significant differences in the eczema area and severity index (EASI) scores, ISGA scores, pruritus numerical rating scale (NRS) scores, or quality-of-life scores between the two groups (all P > 0.05) at any time points, except for the ISGA scores at week 12 (Biw group: 0 [0, 1] point vs. Qod group: 1 [0, 1] point; Z = -2.31, P = 0.021). A total of 146 patients were enrolled in the safety set. During the study period, 70 adverse events occurred in 65 patients, with an incidence rate of 44.5%, and all were mild or moderate adverse events; 55 (37.7%) patients experienced discomfort at the medication site, which mainly referred to pain (45 cases, 30.8%) and mostly occurred in the tender and skinfold areas. Conclusions:Crisaborole 2% ointment could effectively relieve clinical symptoms in children with mild to moderate AD in the early stage, and intermittent treatment could continuously relieve clinical symptoms in the remission stage. The common adverse reaction was discomfort at the application site in the early stage of AD. There was no significant difference in the impact on AD recurrence in the remission stage between the Qod regimen and Biw regimen.
