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.

Liver fibrosis is a vital cause of morbidity in patients with liver diseases and developing novel anti-fibrotic drugs is imperative. Isovalerylspiramycin I (ISP I) as a major component of carrimycin applied to upper respiratory infections, was first found to possess anti-fibrotic potential. The present study aims to evaluate the functions and mechanisms of ISP I in protecting against liver fibrosis. According to our results, ISP I not only reduced the expressions of fibrogenic markers in LX-2 cells but also appeared great protective effects on liver injury and liver fibrosis in bile duct ligation (BDL) rats and carbon tetrachloride (CCl₄) mice. We proved that nucleotide-binding protein 2 (NUBP2) was the direct target of ISP I. ISP I through targeting NUBP2, increased the amount of vascular non-inflammatory molecule-1 (VNN1) on the cell membrane, which will inhibit oxidative stress and fibrosis. Simultaneously, the original carrimycin's protective effect on liver damage and fibrosis was verified. Therefore, our study provides potential agents for patients with liver fibrosis-related diseases, and the clear mechanism supports wide application in the clinic.

The aim of this study is to establish a rapid,efficient,and sensitive method for detecting the infectious laryngotracheitis virus(ILTV).The DNA of ILTV was extracted and used as a tem-plate to develop a recombinant enzyme-mediated isothermal amplification(RAA)fluorescence de-tection method for ILTV through optimization of conditions,sensitivity analysis,and repeatability assessment.Additionally,the nucleic acids of avian influenza virus(AIV),IBV,and Newcastle dis-ease virus(NDV)were detected to verify the specificity of this method.Finally,this method was applied to analyze 59 clinical samples collected from multiple large-scale chicken farms in Hebei Province,and the results were compared with those obtained from real-time fluorescence quantifi-cation(qPCR)and PCR methods according to national standards.The results showed that the RAA detection method established in this study had a reaction system of 25.0 μL buffer,2.1 μL primer,0.6 μL probe,5.0 μL magnesium acetate,and 5.0 μL template.The reaction temperature was 39 ℃ and the amplification time was within 20 minutes.The sensitivity of this method was 101 copies/μL,and the specificity detection was 100％.Testing of 59 clinical samples showed that 17 were detected positive by both RAA fluorescence and qPCR,and 12 were detected by PCR,and the detection rate of RAA(fluorescence)was consistent with real-time fluorescence quantification and qPCR,which was higher than that of the PCR assay.The research results indicate that the RAA fluorescence method has a short detection time,good specificity and sensitivity,and can be used for rapid detection of ILTV.

In order to understand the difference and expression of genes in CEK cells before and af-ter baicalin interferes with IBV,further reveal and analyze the mechanism of baicalin interfering IBV replication in CEK cells in vitro.After IBV infected CEK cells for 2 h,9.75 mg/L baicalin liq-uid was added to interfere with CEK cells,which was recorded as the baicalin(H-IBV)group,and three replicate wells were set in the control group and the IBV(IBV)infection group.After 36 h culture,cell samples were collected and subject to transcriptome for sequencing.The results showed that there were 102 differentially expressed genes in H-IBV group compared with IBV in-fection group,among which 48 genes weresignificantly up-regulated and 54 genes were significantly down-regulated.Through functional annotation in GO and KEGG databases,it was found that dif-ferentially expressed genes were mainly annotated in biological processes such as cellular proces-ses,biological regulation,metabolism,and secondary pathways such as viral infectious diseases,signal transduction and interaction.Retinol metabolism pathway,phospholipid transfer to mem-brane,IL-27 mediated signaling pathway,MDA5/RIG-I and Toll-like receptor signaling pathway were significantly enriched in CEK cells,and the production of type Ⅰ interferon and interferon al-pha and the process of antiviral infection were also positively regulated.There were more differen-tial genes enriched in nucleic acid catalysis,immune system,and reaction,and interbiological reac-tion.Through the STRING network interaction map,it was found that most immune-related genes could form a 36-node interaction network centered on IRF7,TLR3 and STAT1.Therefore,com-pared with IBV group,the differentially expressed genes after baicalin treatment were mainly an-notated and enriched in the biological process,and the immune system and response were en-hanced,mainly through the positive regulation of IRF7 in the MDA5/RIG-I receptor signaling pathway and the inhibition of TLR3 signal transduction in the Toll-like receptor signaling path-way.Positive regulation of IL-27 mediated pathway and regulation of JAK-STAT signaling path-way were supplemented by activation of the expression of IRF7,TLR3,STAT1 and other related genes,and interaction with corresponding downstream proteins to promote the expression of IFN-α and regulatory cytokines,coupled with negative regulation of viral(defense)response and viral processes.Thus,baicalin interferes with IBV replication in CEK cells.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

Objective: To investigate the association between maternal parenting styles and quality of life among preschools，to provide a scientific theoretical basis for interventions targeting at prmoting early life health. Methods: From May to July, 2021, a stratified cluster sampling method was used to enroll 4 233 child mother dyads from 14 preschools in Chengdu. An online questionnaire survey was administered to collect socio demographic information, maternal parenting styles, and children s quality of life. Results: The overall score of quality of life was (80.17±9.81) among preschool children in Chengdu. In the multivariate linear regression models, maternal emotional warmth were significantly associated with higher scores in emotional functioning, social functioning, school functioning, psychosocial health summary score, and total scores ( β coefficients in the high level group were 2.63 , 4.95 , 12.05, 6.54,4.88, P <0.05). In contrast, both maternal rejection and overprotection were significantly associated with lower scores in physical functioning, emotional functioning, social functioning, school functioning, psychosocial health summary score, and the total scores of children s quality of life (for rejection: β coefficients in the high level group were -9.39, -10.82, -7.12 , -6.04 , -8.00, and -8.35 , respectively; for overprotection: β coefficients in the high level group were -6.71, -5.85, -3.08 , -2.39 , -3.77, and - 4.51 , respectively， P <0.05). The associations between high level of maternal rejection and children s emotional functioning showed significant gender differences( β =-3.23, P <0.05). Conclusion Maternal parenting style has a significant impact on children s quality of life. Interventions targeting at maternal parenting styles may be beneficial to improve the quality of life in preschool children.

Objective To observe the effects of transnasal humidified rapid-insufflation ventilatory exchange(THRIVE)on gastric air intake and SpO2 in patients with painless endoscopic mucosal resection(EMR)of colorectal polyps.Methods Seventy patients with painless colorectal polyps EMR,36 males,34 females,aged 18-64 years,BMI 18-25 kg/m2,ASA Ⅰ or Ⅱ.The patients were divided into two groups:high-flow oxygen inhalation group(group T)and conventional oxygen inhalation group(group C)by random number table method,35 cases in each group.Patients in group T were given THRIVE oxygen inhalation,and patients in group C were routinely inhaled oxygen through the nose.During anesthesia,the BIS value was maintained at 50-65.Bedside gastric ultrasonography was used to observe the gastric content and gastric air intake of patients.The HR and resting SpO2 in the supine position were recorded 5 minutes before the surgery(rest for 5 minutes),1 minute after entering the endoscope,when entering the endoscope to the ileocecal valve,and at the end of the surgery.The PaCO2,PaO2 and pH values were recorded 5 mi-nutes before surgery,when entering the endoscope to the ileocecal valve,and at the end of the surgery,so were gastric intake and satiety,and antral cross-sectional area(CSA)for 5 minutes before surgery and after surgery.The occurrence of mild,moderate,and severe hypoxia during anesthesia were recorded.The opera-tion time,the amount of propofol used during the operation,the number of dosage times of remifentanil,PACU residence time,and infusion during surgery,the occurrence of adverse reactions such as hypotension,hypertension,bradycardia,reflux aspiration,postoperative nausea and vomiting,and the sat-isfaction score of digestive endoscopy physicians and patients were recrded.Results Compared with group C,SpO2 in group T was significantly increased 1 minutes after entering the endoscope(P＜0.05),and PaCO2 was significantly decreased at the time of entering the endoscope to the ileocecal valve and the end of the surgery(P＜0.05),the incidence of mild and moderate hypoxia was significantly reduced in group T(P＜0.05).No positive gastric air intake and full stomach were found in both groups at rest for 5 minutes and after the surgery.There was no significant difference in the incidence of adverse reactions and patient satisfaction scores between the two groups.The satisfaction score of endoscopists in group T was significantly higher than that in group C(P＜0.05).Conclusion Compared with conventional nasal catheter oxygen inhalation,THRIVE ventilation does not cause hypercapnia or affect gastric intake and stomach content,does reduce the occurrence of mild to moderate hypoxia in patients undergoing painless EMR,does not in-crease the risk of reflux aspiration,and has a higher satisfaction of digestive endoscopy physicians.
