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.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Background/Aims: The histological characteristics and natural history of precirrhotic primary biliary cholangitis (PBC) with portal hypertension (PH) are unclear. Our aim was to clarify the prevalence, risk factors, and histological characteristics of precirrhotic PBC patients with PH. Methods: This retrospective study compared the clinical features, histological characteristics, and response to ursodeoxycholic acid (UDCA) between the PH and non-PH groups of precirrhotic PBC patients. Results: Out of 165 precirrhotic PBC patients, 40 (24.2%) also had PH. According to histological stage 1, 2 and 3 disease, 5.3% (1/19), 17.3% (17/98), and 45.8% (22/48) of patients also had PH, respectively. Precirrhotic PBC with PH was significantly positively correlated with bile duct loss, degree of cytokeratin 7 positivity, and degree of fibrosis in the portal area, but significantly negatively correlated with lymphoid follicular aggregation. Compared to the non-PH group, patients in the PH group showed a higher prevalence of obliterative portal venopathy, incomplete septal fibrosis, portal tract abnormalities and non-zonal sinusoidal dilatation (p<0.05). In addition, patients with PH were more likely to present with symptoms of jaundice, ascites, epigastric discomfort, a poorer response to UDCA, and more decompensation events (p<0.05). High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values were risk factors for precirrhotic PBC with PH. Conclusions Approximately 24.2% of precirrhotic PBC patients have PH, which is histologically related to the injury of bile ducts. High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values are associated with increased risk of precirrhotic PBC with PH.

OBJECTIVE: To explore the specific pharmacological molecular mechanisms of Laoke Formula (LK) on treating advanced non-small cell lung cancer (NSCLC) based on clinical application, network pharmacology and experimental validation. METHODS: Kaplan-Meier method and Cox regression analysis were used to evaluate the survival benefit of Chinese medicine (CM) treatment in 296 patients with NSCLC in Tianjin Medical University Cancer Institute and Hospital from January 2011 to December 2015. The compounds of LK were screened using the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform, and the corresponding targets were performed from Swiss Target Prediction. NSCLC-related targets were obtained from Therapeutic Target Database and Comparative Toxicogenomics Database. Key compounds and targets were identified from the compound-target-disease network and protein-protein interaction (PPI) network analysis, respectively. Kyoto Encyclopedia of Genes and Genomes (KEGG) and Gene Ontology (GO) enrichment analysis were used to predict the potential signaling pathways involved in the treatment of advanced NSCLC with LK. The binding affinities between key ingredients and targets were further verified using molecular docking. Finally, A549 cell proliferation and migration assay were used to evaluate the antitumor activity of LK. Western blot was used to further verify the expression of key target proteins related to the predicted pathways. RESULTS: Kaplan-Meier survival analysis showed that the overall survival of the CM group was longer than that of the non-CM group (36 months vs. 26 months), and COX regression analysis showed that LK treatment was an independent favorable prognostic factor (P=0.027). Next, 97 components and 86 potential targets were included in the network pharmacology, KEGG and GO analyses, and the results indicated that LK was associated with proliferation and apoptosis. Moreover, molecular docking revealed a good binding affinity between the key ingredients and targets. In vitro, A549 cell proliferation and migration assay showed that the biological inhibition effect was more obvious with the increase of LK concentration (P<0.05). And decreased expressions of nuclear factor κB1 (NF-κB1), epidermal growth factor receptor (EGFR) and AKT serine/threonine kinase 1 (AKT1) and increased expression of p53 (P<0.05) indicated the inhibitory effect of LK on NSCLC by Western blot. CONCLUSION LK inhibits NSCLC by inhibiting EGFR/phosphoinositide 3-kinase (PI3K)/AKT signaling pathway, NFκB signaling pathway and inducing apoptosis, which provides evidence for the therapeutic mechanism of LK to increase overall survival in NSCLC patients.

Aim To investigate the effects of Evodiamine (EVO) on proliferation and apoptosis of human leukemia cell line K562 and its potential mechanisms. Methods K562 cells were treated with EVO at different concentrations (0, 1, 2, 4, 8, 16, 32, 64 jxmol • L

Objective: To evaluate the effectiveness and safety of percutaneous nephrolithotomy(PCNL) with the all-seeing needle system(Microperc)for the treatment of upper urinary calculi in children. Methods: Retrospective analysis of 25 cases of upper urolithiasis treated with Microperc from November 2016 to January 2018 in Guizhou Provincial People′s Hospital was performed, including 18 boys and 7 girls.The age of patients was (6.4±3.9) years(10 months-14 years), and 4 cases were less than 3 years old.Among them, 3 cases had upper ureteral calculi and 22 cases had renal calculi.The mean stone size was 14.5 mm(8-20 mm). Stone fragmentation was performed by using a 200 μm holmium(YAG laser fiber). Results: All patients were successfully treated in stage I. In 6 patients, access was achieved through the 4.8Fr all-seeing needle method.Conversion to mini-PCNL (10-12Fr) was required in 19 patients due to intraoperative bleeding and high stone burden.The duration of operation time was (60.8±15.1) min (40-100 min). The mean postoperative drop in hemoglobin was (7.5±5.4) g/L, and no patient required blood transfusion.The hospital stay was (4.9±1.2) days (3-6 days). There were residual fragments in 3 patients, and the overall stone-free rate at 4 weeks was 88%(22/25 cases). Four cases had a fever(Clavien grade Ⅰ) complications, while no grade Ⅱ and grade Ⅲ complications were observed. Conclusions Microperc can establish a surgical channel through visual images quickly and safely, and it greatly reduces the risk and difficulty in doing operation.This technology is not only suitable for learner of surgery, but also for patients with mild hydronephrosis and children with calculus.

Objective To establish a method for extracting and detecting circulating microRNAs(miRNAs) in plasma and to detect the distribution of miR-192,miR-206 and miR-613 in Chinese Han people.Methods The total RNA was extracted from 116 healthy subjects plasma by Trizol LS and then tested by reverse transcription-quantitative polymerase chain reaction (RT-qPCR) method.The expression level of circulating miR-192,miR-206 and miR-613 was standardized by eel-39.Results The △Ct values of circulating miR-192,miR-206 and miR-613 in 116 healthy subjects plasma were 14.01 ± 4.19,17.63 ±4.42 and 19.77 ±4.68,respectively.The expression of plasma circulating miR-192 was significantly higher than miR-206 and miR-613 (P ＜0.05).After grouped by quarrles,the differences of circulating miR-192,miR-206 and miR-613 among four groups were statistically significant (P ＜ 0.05).Conclusion The expression of circulating miR-192,miR-206 and miR-613 in Chinese Han people was distributed normally and showed significant differences.

The aims of the present study were to determine the effects of heparin-derived oligosaccharides (HDOs) on vascular intimal hyperplasia (IH) in balloon-injured carotid artery and to elucidate the underlying mechanisms of action. An animal model was established by rubbing the endothelia within the common carotid artery (CCA) in male rabbits. The rabbits were fed a high-cholesterol diet. Arterial IH was determined by histopathological changes to the CCA. Serum lipids were detected using an automated biochemical analysis. Expressions of mRNAs for vascular endothelial growth factor (VEGF), basic fibroblast growth factor (bFGF), vascular cell adhesion molecule-1 (VCAM-1), monocyte chemoattractant protein-1 (MCP-1), scavenger receptor class B type I (SR-BI), and ATP-binding cassette transporter A1 (ABCA-1) were analyzed using reverse transcription polymerase chain reaction assays. Expressions of VEGF, VCAM-1, MCP-1, SR-BI and ABCA-1 proteins were analyzed by Western blotting. Enzyme-linked immunosorbent assays were used to quantify expression levels of VEGF and bFGF. Our results showed that administration of HDO significantly inhibited CCA histopathology and restenosis induced by balloon injury. The treatment with HDOs significantly decreased the mRNA and protein expression levels of VEGF, bFGF, VCAM-1, MCP-1, and SR-BI in the arterial wall; however, ABCA-1 expression level was elevated. HDO treatment led to a reduction in serum lipids (total cholesterol, triglycerides, high-density and low-density lipoproteins). Our results from the rabbit model indicated that HDOs could ameliorate IH and underlying mechanism might involve VEGF, bFGF, VCAM-1, MCP-1, SR-BI, and ABCA-1.
