Objective To explore the prognostic value of glycolysis-related genes in colorectal cancer (CRC) patients and formulate a novel glycolysis-related prognostic risk model. Methods Single-cell and bulk transcriptomic data of CRC patients, along with clinical information, were obtained from The Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases. Glycolysis scores for each sample were calculated using single-sample Gene Set Enrichment Analysis (ssGSEA). Kaplan-Meier survival curves were generated to analyze the relationship between glycolysis scores and overall survival. Novel glycolysis-related subgroups were defined among the cell type with the highest glycolysis scores. Gene enrichment analysis, metabolic activity assessment, and univariate Cox regression were performed to explore the biological functions and prognostic impact of these subgroups. A prognostic risk model was built and validated based on genes significantly affecting the prognosis. Gene Set Enrichment Analysis (GSEA) was conducted to explore differences in biological processes between high- and low-risk groups. Differences in immune microenvironment and drug sensitivity between these groups were assessed using R packages. Potential targeted agents for prognostic risk genes were predicted using the Enrichr database. Results Tumor tissues showed significantly higher glycolysis scores than normal tissues, which was associated with a poor prognosis in CRC patients. The highest glycolysis score was observed in epithelial cells, within which we defined eight novel glycolysis-related cell subpopulations. Specifically, the P4HA1⁺ epithelial cell subpopulation was associated with a poor prognosis. Based on signature genes of this subpopulation, a six-gene prognostic risk model was formulated. GSEA revealed significant biological differences between high- and low-risk groups. Immune microenvironment analysis demonstrated that the high-risk group had increased infiltration of macrophages and tumor-associated fibroblasts, along with evident immune exclusion and suppression, while the low-risk group exhibited higher levels of B cell and T cell infiltration. Drug sensitivity analysis indicated that high-risk patients were more sensitive to Abiraterone, while low-risk patients responded to Cisplatin. Additionally, Valproic acid was predicted as a potential targeted agent. Conclusion High glycolytic activity is associated with a poor prognosis in CRC patients. The novel glycolysis-related prognostic risk model formulated in this study offers significant potential for enhancing the diagnosis and treatment of CRC.

Objective To explore the efficacy of the self-formulated Zhuzhang Formula in trea-ting the spleen deficiency with dysfunction of transportation syndrome of idiopathic short stature(ISS)and its effects on the growth rate,disease-related indicators,and bone metabolism indicators in affect-ed children.Methods A total of 80 children with ISS were enrolled as study subjects.They were randomly assigned to control group and observation group using random number table method,with 40 cases in each group.The control group received conventional western medicine treatment,while the observation group was administered self-formulated Zhuzhang Formula in addition to the treatment of the control group.Comparisons were made between the two groups in terms of clinical efficacy,TCM syndrome scores,growth parameters(monthly average height increment,annual growth rate),levels of disease-related indicators[serum insulin-like growth factor-1(IGF-1),bone morphogenetic pro-tein-2(BMP-2),insulin-like growth factor binding protein-3(IGFBP-3)],levels of bone metabo-lism indicators[bone alkaline phosphatase(BAP),type Ⅰ procollagen N-terminal propeptide(PⅠNP),type Ⅰ collagen cross-linked C-terminal telopeptide(β-CTX)],and the incidence of adverse reac-tions.Results The overall effective rate in the observation group was 97.50％,which was significantly higher than the 80.00％ in the control group(P＜0.05).After 3 and 6 months of intervention,the scores for symptoms such as short stature,sallow complexion,loss of appetite,weak voice and shortness of breath,limb weakness,and loose stools,as well as the total TCM syndrome scores,were lower in the observation group than those in the control group,with statistically significant differences(P＜0.05).After 6 months of intervention,the monthly average height increment and annual growth rate were higher in the observation group than those in the control group,and the differences were statistically significant(P＜0.05).After 3 and 6 months of intervention,the levels of IGF-1,BMP-2,IGFBP-3,BAP,and PⅠNP were higher in the observation group than those in the control group,while the level of β-CTX was lower,and the differences were statistically significant(P＜0.05).There was no statistically significant difference in the incidence of adverse reactions between the two groups(P＞0.05).Conclusion The self-formulated Zhuchang Formula demon-strates remarkable efficacy in treating the spleen deficiency with dysfunction of transportation syndrome of ISS.It can alleviate clinical symptoms by regulating the levels of IGF-1,BMP-2,IGFBP-3,and bone metabolism indicators,thereby promoting the growth and development of affected children,and exhibits high safety.

Sepsis-associated delirium(SAD)is a common and severe central nervous system(CNS)complication in patients with sepsis,whose occurrence mechanism is unclear and there is no effective treatment at present.Neuroendocrine immune regulation disorder is closely related to occurrence and development of SAD.Immune mediators can deliver peripheral immune information to CNS by humoral transport or through afferent nerves.Immune mediators invading center can not only directly damage neurons,but also activate innate immune cells of brain,further aggravate neuroinflammation,and cause neurotransmitter imbalance,neurotoxic effects,resulting in neuronal dysfunction,even apoptosis and subsequent behavioral and cognitive symptoms.This paper aims to review mechanisms of neuro-endocrine-immune regulation in occurrence and development of SAD,and to find effective targets for prevention and treatment of sepsis and SAD.

Objective: To evaluate the clinical characteristics and outcomes of very high risk patients with primary immunoglobulin light-chain amyloidosis (pAL) at a single center in China. Method: Clinical data, treatment and outcome of 205 pAL patients in Peking Union Medical College Hospital from January 2009 to February 2016 were retrospectively analyzed. A 'very high risk’ group includes patients with Mayo 2004 stage Ⅲb and Mayo 2012 stage 4. Results: Of 205 patients, 34 (16.6%) were defined as very high risk pAL patients. The median age at diagnosis was 57 (20-84) years, and 22 patients (64.7%) were male. All 34 patients were diagnosed with cardiac involvement, multi-organ involvement was observed in 15 patients (44.1%) , and 27 (81.8%) had New York Heart Association Class Ⅲ or Ⅳ. Median values of serum cTnI, NT-proBNP, and free light chains difference were 0.25 μg/L, 11 733 ng/L, and 403 mg/L, respectively. Eight (24.2%) had more than 10% plasma cell on the bone marrow aspirate. Sixteen (47.1%) patients received bortezomib based chemotherapy and overall hematologic response rate was 58.3%. Median overall survival (OS) was 4 months. The estimated OS at 3, 6, 12, and 24 months was 51.3%, 44.0%, 35.2%, and 29.6%, respectively. Fourteen (41.2%) patients died within 3 months after the diagnosis. The estimated 1-year survival rate for the patients who got hematologic response, without hematologic response, and palliative treatment was 90.9%, 11.1%, and 0, respectively (P<0.001) . Conclusion Patients with very high risk pAL had very poor prognosis and the early death rate remained high. Those patients who obtained hematologic remission would have significantly better outcomes.
