Hypothermia is a clinical syndrome characterized by core body temperature<35℃,caused by significant heat loss from body surface in cold environment.As a systemic cold injury,it can be lethal if treatment is delayed.Emergent diagnosis and treatment of hypothermia are expected to improve the prognosis of patients.In 2005,the U.S.Army Research Institute of Environmental Medicine(USARIEM)issued guidelines for the prevention and management of cold injuries,but there has been no corresponding standard in China.Therefore,Emergency Branch of Chinese Medical Rescue Association,Emergency Medical Equipment Society of China Association of Medical Equipment,Integrated Rehabilitation Medical Branch of Chinese Medical Rescue Association,and Pre-Hospital Emergency Care Working Committee of Chinese Aging Well Association jointly developed the Chinese Expert Consensus on Emergent Treatment of Hypothermia(2025 edition).The consensus covers the pathophysiology,etiology and epidemiology,diagnosis and severity grading,prehospital treatment,and in-hospital treatment of hypothermia,including 15 recommendations in total,aiming to provide guidance for the relevant clinical rescue work.

Objective:To investigate the effect of KRAS,NRAS and BRAF gene mutations on the efficacy of pre-operative short-course radiotherapy combined with chemotherapy and postoperative liver metastasis in patients with stage Ⅱ～Ⅲ mid-low rectal cancer.Methods:The clinical data of 149 patients with stage Ⅱ～Ⅲ low rectal cancer admitted to Dongnan Hospital of Xiamen University from January 2017 to June 2020 were retrospectively analyzed.All patients received neoadjuvant therapy with preoperative short-course radiotherapy combined with chemotherapy and radical surgery,and were followed up until June 30,2023.The mutations of KRAS,NRAS and BRAF genes were de-tected by pathological tissue before surgery.The effect of neoadjuvant therapy was evaluated according to tumor re-gression grade(TRG).The risk factors of postoperative liver metastasis were analyzed by Logistic multivariate analysis.Results:There were 44 cases of KRAS,10 cases of NRAS and 12 cases of BRAF gene mutation in 149 patients with stage Ⅱ～Ⅲ low rectal cancer,and the mutation rates were 29.53%,6.71%and 8.05%.The incidence of positive vas-cular invasion in patients with KRAS gene mutation was higher than negative(P＜0.05).In NRAS mutation patients,the incidence of positive lymph node metastasis was higher than negative(P＜0.05),and the incidence of maximum tumor diameter≥5 cm was higher than that of maximum tumor diameter＜5 cm(P＜0.05).The clinical stage of BRAF muta-tion was higher in stage Ⅲ than in stage Ⅱ(P＜0.05),and the incidence of positive lymph node metastasis was higher than negative(P＜0.05).During the follow-up period,liver metastasis occurred in 42 patients,and the liver metastasis rate was 28.18%.The KRAS,NRAS and BRAF gene mutations in the effective group were 25.81%,2.15%and 3.23%,lower than those in the ineffective group(35.71%,14.29%and 17.07%,P＜0.05).Multiple factors found clinical stage Ⅲ(OR=10.620,95%CI:2.645～22.575),lymph node metastasis was positive(OR=8.774,95%CI:1.878～19.645),neoadju-vant therapy failed(OR=3.373,95%CI:1.014～11.218),KRAS gene mutation(OR=6.245,95%CI:1.876～20.789),BRAF gene mutation(OR=9.497,95%CI:1.754～19.335)were independent risk factors for postoperative liver metastasis of stage Ⅱ～Ⅲ mid-low rectal cancer.Conclusion:Mutations in the KRAS and BRAF genes of middle are associated with poorer efficacy of neoadjuvant therapy in patients with stage Ⅱ～Ⅲ mid-low rectal cancer and are also indepen-dent risk factors for postoperative liver metastasis.

Objective To summarize the clinical and genetic characteristics of children with sodium taurocholate co-transporting polypeptide(NTCP)deficiency.Methods Clinical data of children with NTCP deficiency diagnosed and treated at the First People's Hospital of Yunnan Province from July 2022 to March 2025 were retrospectively analyzed.Results A total of 14 children were included(6 males,8 females),all with normal growth and development.Reasons for initial consultation included elevated serum bile acids in 7 cases,jaundice in 4 cases,cholestatic hepatitis in 1 case,and one case each of pneumonia and cow's milk protein allergy.At the first visit,all patients had elevated serum total bile acids beyond the normal range,with a mean of 152.5 μmol/L.Elevated alanine aminotransferase was observed in 1 case,elevated aspartate aminotransferase in 2 cases,and elevated total bilirubin in 10 cases.Genetic sequencing revealed that all children carried the homozygous SLC10A1 variant c.800C>T(p.Ser267Phe),classified as likely pathogenic.Conclusions NTCP deficiency often lacks obvious clinical symptoms and signs.Some children present with transient hyperbilirubinemia,cholestasis,or other liver function abnormalities.Persistent isolated elevation of serum bile acids warrants suspicion for this disease.Biallelic pathogenic variants in SLC10A1 constitute the basis for definitive diagnosis.There is no specific treatment for this disease,and management is mainly symptomatic.

Objective To explore the distribution patterns of traditional Chinese medicine(TCM)syndromes in patients with metabolic syndrome caused by antipsychotic drugs.Methods A standardized TCM syndrome survey was performed to collect diagnostic information from 160 patients diagnosed with metabolic syndrome due to antipsychotic drug use.Subsequent frequency analysis,cluster analysis,and Bayesian network analysis were carried out.The syndrome pattern distribution was ultimately determined through relevant literatures and expert opinions.Results Five TCM syndromes were identified through frequency,cluster,and Bayesian network analyses.The most common syndrome was qi deficiency with phlegm-dampness(30％),followed by spleen deficiency with phlegm-Heat(23.75％),qi and yin deficiency Pattern(21.88％),yin deficiency with damp-heat(17.50％),and stomach fire hyperactivity pattern(6.88％).Conclusion The pathogenesis of antipsychotics-induced metabolic syndrome involves a complex interplay of deficiency and excess factors.The primary disease is mainly located at the spleen and stomach,with involvement of the liver,kidney,and heart.Pathogenic factors include qi deficiency,yin deficiency,dampness,heat,pathogenic fire,and phlegm.

Objective To investigate biological markers associated with psychotic symptoms in patients with bipolar disorder(BD)based on electronic medical records of patients,and to develop an interpretable risk prediction model that supports the identification of high-risk individuals and that facilitates decision-making for providing clinical intervention in a timely manner.Methods A total of 2 352 patients diagnosed with BD and admitted to West China Hospital,Sichuan University were enrolled using the electronic medical records system of the hospital.The participants were divided into two subgroups,the bipolar disorder depression(BDD)group and the bipolar disorder mania(BDM)group.The logistic regression algorithm was used to train and validate the prediction model,and interpretability methods were used to analyze the contribution of each feature to individuals and the effect of the features on specific target prediction decisions.Results The logistic regression model demonstrated robust predictive performance across the BD,BDD,and BDM cohorts,with areas under the curve(AUC)of the receiver operating characteristic curves always exceeding 81.6%.The core predictive features included platelet distribution width(PDW),fibrinogen(FIB),platelet large cell ratio(P-LCR),activated partial thromboplastin time(APTT),prothrombin time(PT),and triglyceride(TG).The logistic regression model exhibited strong interpretability and was combined with nomograms for intuitive risk quantification and individualized prediction.Conclusion The logistic regression model enables rapid and simple screening of BD patients with psychotic symptoms.Distinct patterns of changes observed in blood biomarkers of BDD and BDM subgroups enrich the understanding of the underlying pathophysiological mechanisms and highlight the importance of considering subtypes in the intervention and management of patients.

OBJECTIVE To investigate the pharmacodynamics and related mechanisms of Anmei Dan on hippocampus of mice with coronary heart disease complicated with depression.METHODS The coronary heart disease model combined with chronic and unpredictable mild stress depression model was established,and the mice were randomly divided into blank group,model group,low dose group(1.5 g·kg-1),high dose group(3 g·kg-1)and atorvastatin group(0.3 g·kg-1).Sucrose preference test,open field test and forced swimming test were used to evaluate the behavioral changes of mice.qPCR and ELISA were employed to ascertain the mR-NA expression of interleukin-1β(IL-1β),interleukin-6(IL-6)and tumour necrosis factor-α(TNF-α)in the hippocampus.The changes of neurons and Nissl bodies in CA1,CA3 and DG regions of hippocampus were observed by Nissl staining.The expression of key proteins was detected by Western blot.RESULTS Compared with the blank group,the sucrose preference rate of mice in the model group was decreased(P<0.01),the forced swimming immobility time was extended(P<0.01)and the movement distance in the open field experiment was not significantly changed.The levels of total cholesterol(TC),triglyceride(TG)and low density lipopro-tein cholesterol(LDL-C)were increased significantly(P<0.01)and the level of high density lipoprotein cholesterol(HDL-C)was decreased significantly(P<0.01).The mRNA level and content of IL-1β,IL-6 and TNF-α were significantly increased(P<0.01).The expression of glutamate receptor 1(GluR1),postsynaptic densitin-95(PSD-95),brain-derived neurotrophic factor(BDNF)and phosphorylated calmodulin-dependent kinase(p-CaMKⅡ)in hippocampus was decreased(P<0.01).The expression of cytoskeletal activity regulatory protein(Arc)was increased(P<0.01).In the model group,the cell structure was irregular and differ-ent degrees of damage occurred,the Nissl bodies decreased or disappeared,and the cell membrane broke.Compared with the model group,the sucrose preference rate of mice in each administration group was significantly increased(P<0.01),the immobility time in forced swimming experiment was significantly decreased(P<0.01),and the levels of TC,TG and LDL-C of mice in Anmei Dan groups and atorvastatin group were decreased(P<0.01),while the level of HDL-C increased(P<0.01).The mRNA levels and con-tent of IL-1β,IL-6 and TNF-α in Anmei Dan groups and atorvastatin group were decreased(P<0.01).The expression of GluR1,PSD-95,BDNF and p-CaMKⅡ in hippocampal tissue of Anmei Dan groups were increased(P<0.01),and the expression of Arc was decreased(P<0.01).The morphology and structure of the cells in the Anmei Dan group and the atorvastatin group were improved,with varying degrees of increased Nissl bodies and relatively intact cell membranes.CONCLUSION Anmei Dan can effectively im-prove blood lipids and depression-like behavior of coronary heart disease mice complicated with depression.It can inhibit pro-inflam-matory factors,increase the expression of neurotrophic factors,effectively improve synaptic related proteins,and reduce the damage to neurons,thus effectively preventing the exacerbation of coronary heart disease and depression comorbidity.

High-performance liquid chromatography(HPLC) was used to determine the content of three major components in Citri Reticulatae Semen(CRS), including limonin, nomilin, and obacunone. The chromaticity of the CRS sample during salt processing and stir-frying was measured using a color difference meter. Next, the relationship between the color and content of the salt-processed CRS sample was investigated through correlation analysis. By integrating the oil bath technique for processing simulation with HPLC, the changes in the relative content of nomilin and its transformation products were analyzed, with its structural transformation pattern during processing identified. Additionally, RAW264.7 cells were induced with lipopolysaccharides(LPSs) to establish an inflammatory model, and the anti-inflammatory activity of nomilin and its transformation product, namely obacunone was evaluated. The results indicated that as processing progressed, E~*ab and L~* values showed a downward trend; a~* values exhibited a slow increase over a certain period, followed by no significant changes, and b~* values remained stable with no significant changes over a certain period and then started to decrease. The limonin content remained barely unchanged; the nomilin content decreased, and the obacunone increased significantly. The changing trends in content and color parameters during salt-processing and stir-frying were basically consistent. The content of nomilin and obacunone was significantly correlated with the colorimetric values(L~*, a~*, b~*, and E~*ab), while limonin content showed no significant correlation with these values. By analyzing HPLC patterns of nomylin at different heating temperatures and time, it was found that under conditions of 200-250 ℃ for heating of 5-60 min, the content of nomilin significantly decreased, while the obacunone content increased pronouncedly. The in vitro anti-inflammatory activity results indicated that compared to the model group, the group with a high concentration of nomilin and the groups with varying concentrations of obacunone showed significantly reduced release of nitric oxide(NO)(P<0.01). When both were at the same concentration, obacunone showed better performance in inhibiting NO release. In this study, the obvious correlation between the color and content of major components during the processing of CRS samples was identified, and the dynamic patterns of quality change in CRS samples during processing were revealed. Additionally, the study revealed and confirmed the transformation of nomilin into obacunone during processing, with the in vitro anti-inflammatory activity of obacunone significantly greater than that of nomilin. These findings provided a scientific basis for CRS processing optimization, tablet quality control, and its clinical application.
