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:Acoustic neuroma(AN)is a benign tumor that usually affects a patient's hearing and balance function.For the screening and diagnosis of AN,the traditional approach mainly relies on audiological examination and magnetic resonance imaging(MRI),often ignoring the importance of vestibular function assessment in the affected area.As an emerging method of vestibular function detection,video head impulse test(vHIT)has been widely used in clinic,but research on its use in AN diagnosis is relatively limited.This study aims to explore the value of vHIT in the diagnosis of AN,vestibular dysfunction assessment,and postoperative compensation establishment in unilateral AN patients undergoing unilateral AN resection through labyrinthine approach. Methods:This retrospective study was conducted on 27 AN patients who underwent unilateral AN resection via labyrinthine approach from October 2020 to March 2022 in the Department of Otolaryngology-Head and Neck Surgery,the Second Xiangya Hospital,Central South University.vHIT was performed 1 week before surgery to assess vestibular function,pure tone audiometry(PTA)was used to assess hearing level,and ear MRI was used to assess tumor size.Follow-up vHIT was conducted at 1 week,1 month,6 months,and 1 year post-surgery.The correlation of vHIT with hearing and tumor size was analyzed. Results:Preoperative vHIT showed that the posterior semicircular canal on the affected side was the most common semicircular canal with reduced vestibulo-ocular reflex(VOR)gain.There was a correlation between the VOR gain of vHIT on the affected side and the hearing level(r=-0.47,P<0.05)or tumor size(r=-0.54,P<0.01).The results of vHIT on the affected side showed that the hearing level and mean VOR gain of the anterior semicircular canal increased slightly with time,and the amplitude and saccade percentage of the dominant saccades of the 3 semicircular canals increased,while the latency time decreased,with the most obvious changes occurring 1 week post-surgery. Conclusion:vHIT can effectively monitor the changes of vestibular function in AN patients before and after surgery and has application value in assisting the diagnosis of vestibular dysfunction in AN patients.

ObjectiveTo explore the syndrome elements and evolving patterns of patients with hepatitis B virus-related acute on chronic liver failure （HBV-ACLF） at different stages. MethodsClinical information of 1,058 hospitalized HBV-ACLF patients， including 618 in the early stage， 355 in the middle stage， and 85 in the late stage， were collected from 18 clinical centers across 12 regions nationwide from January 1， 2012 to February 28， 2015. The “Hepatitis B-related Chronic and Acute Liver Failure Chinese Medicine Clinical Questionnaire” were designed to investigate the basic information of the patients， like the four diagnostic information （including symptoms， tongue， pulse） of traditional Chinese medicine （TCM）， and to count the frequency of the appearance of the four diagnostic information. Factor analysis and cluster analysis were employed to determine and statistically analyze the syndrome elements and patterns of HBV-ACLF patients at different stages. ResultsThere were 76 four diagnostic information from 1058 HBV-ACLF patients， and 53 four diagnostic information with a frequency of occurrence ≥ 5% were used as factor analysis entries， including 36 symptom information， 12 tongue information， and 5 pulse information. Four types of TCM patterns were identified in HBV-ACLF， which were liver-gallbladder damp-heat pattern， qi deficiency and blood stasis pattern， liver-kidney yin deficiency pattern， and spleen-kidney yang-deficiency pattern. In the early stage， heat （39.4%， 359/912） and dampness （27.5%， 251/912） were most common， and the pattern of the disease was dominated by liver-gallbladder damp-heat pattern （74.6%， 461/618）； in the middle stage， dampness （30.2%， 187/619） and blood stasis （20.7%， 128/619） were most common， and the patterns of the disease were dominated by liver-gallbladder damp-heat pattern （53.2%， 189/355）， and qi deficiency and blood stasis pattern （27.6%， 98/355）； and in the late stage， the pattern of the disease was dominated by qi deficiency （26.3%， 40/152） and yin deficiency （20.4%， 31/152）， and the patterns were dominated by qi deficiency and blood stasis pattern （36.5%， 31/85）， and liver-gallbladder damp-heat pattern （25.9%， 22/85）. ConclusionThere are significant differences in the distribution of syndrome elements and patterns at different stages of HBV-ACLF， presenting an overall trend of evolving patterns as "from excess to deficiency， transforming from excess to deficiency"， which is damp-heat → blood stasis → qi-blood yin-yang deficiency.

Objective To observe the intervention effect of acupuncture at"Zusanli"(ST36)or"Neiguan"(PC6)on the ulcerative colitis(UC)model mice.And to analyze the similarities and differences of gene transcription expression between the diseased colon and the non-diseased heart after acupuncture intervention by using transcriptomics,to explore whether there are efficacy differences between the two acupoints.Methods The UC mouse model was established by inducing dextran sulfate sodium salt(DSS).After successful modeling,the mice were randomly divided into model group,Zusanli group,and Neiguan group,with 9 mice in each group.Zusanli group and Neiguan group intervened with acupuncture at"Zusanli"and"Neiguan",respectively,30 min each time,once a day,for 5 consecutive days.The control and model groups were only bound without acupuncture.Observe the general situation of mice in each group,calculate the disease activity index(DAI),observe the morphological changes of colon tissue by HE staining.Use transcriptome sequencing technology to sequence and biologically analyze the colon tissue of mice in each group,and compare and study whether the two acupoints have differences in acupoint efficacy from the perspective of diseased tissue.At the same time,take the heart tissues of each group for comparative analysis,and discuss whether the effects of the two acupoints are different from the perspective of non-diseased tissue.Results Compared with control group,the DAI score of the model group increased significantly(P<0.001),and HE staining results showed significant pathological damage;after acupuncture at Zusanli or Neiguan,the DAI scores of UC mice were reduced considerably(P<0.05),and the pathological damage was significantly improved.The results of transcriptome sequencing and bioinformatics analysis showed that the effects of acupuncture at Zusanli or Neiguan on the colon of diseased tissue involved multiple genes,and 825 differential genes with similar changes(co-DEGs)were mainly enriched in white blood cells and chemokine pathways;there were 168 differentially expressed genes(ST36 only-DEGs)affected only by Zusanli,which were enriched to gastric acid secretion and other pathways;there were 325 differentially expressed genes(PC6 only-DEGs)only affected by Neiguan,which were enriched in cytokine-cytokine receptor interaction and other pathways.There were 95 co-DEGs in the heart of non-diseased tissue,which were mainly enriched in positive regulation of defense response and response to interleukin-1;there were 28 ST36 only-DEGs;there were114 PC6 only-DEGs,which were enriched in cardiovascular diseases and other pathways.Conclusion Acupuncture of"Zusanli"and"Neiguan"could improve UC mice's symptoms and pathological colon changes.However,through transcriptomic analysis,it was found that the two acupoints had differences in gene transcription effects on the colon of diseased tissue and the heart of non-diseased tissue,suggesting that acupoints with different distribution positions had some similarities in macro efficacy.Still,there were some differences at a micro level.
