Esophageal cancer （EC） is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， as one of the key oncogenic pathways， can promote the cell cycle progression， proliferation， migration， and invasion， induce chemoresistance， and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine （TCM）， with the advantages of targeting multiple points with multiple components to delay cancer progression， can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum， spore powder of Ganoderma lucidum without spore coat， extract of Celastrus orbiculatus， root extract of Taraxacum， and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids， terpenoids， saponins， phenols， polysaccharides， alkaloids， and other compounds. TCM compound prescriptions with such effect include Qige San， Huqi San， Xuanfu Daizhetang， Tongyoutang and its decomposed prescriptions， Liujunzi Tang， and Xishenzhi Formula. In addition， TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions， aiming to provide reference for the research and clinical application of new drugs for EC.

BACKGROUND:Obesity is not only related to metabolic diseases such as diabetes and cardiovascular disease,but also closely related to the increased risk of cognitive decline,dementia and other neurodegenerative diseases.Studies have found that aerobic exercise and resistance exercise can help improve obesity-related cognitive impairment,but their therapeutic effects and related mechanisms of action are still unclear.OBJECTIVE:To explore the protective effects of aerobic and resistance exercises on the nervous center of obesity-related cognitive impairment mice.METHODS:Forty-eight 8-week-old C57BL/6J wild-type male mice were randomly divided into four groups:a control group was fed normally for 20 weeks;a high fat group was fed with high fat diet(60％fat energy)for 20 weeks;an aerobic exercise group was fed with 12 weeks of high-fat diet followed by 8 weeks of aerobic exercise;and a resistance exercise group was fed with 12 weeks of high-fat diet followed by 8 weeks of resistance exercise.After the exercise intervention,body mass was weighed,insulin tolerance and glucose tolerance were tested to evaluate insulin resistance,and cognitive function of mice in each group was detected by new object recognition experiment and Y-maze experiment.The morphology of hippocampal and cortical tissue cells was observed by hematoxylin-eosin staining.The mRNA relative expression levels of tumor necrosis factor-α and interleukin-6 were detected by real-time fluorescence quantitative PCR,and the protein expressions of Bax,Bcl-2,nuclear factor-κB,Cleaved Caspase-1,Caspase-3,synapsin 1 and brain-derived neurotrophic factor were detected by western blot.RESULTS AND CONCLUSION:(1)Compared with the control group,the body mass of mice increased in the high-fat group(P＜0.05),accompanied by insulin resistance and cognitive dysfunction,the expression levels of nuclear factor-κB,Bax,Caspase-3,Cleaved Caspase-1 in the hippocampus were significantly increased(P＜0.05),the expression levels of brain-derived neurotrophic factor,synapsin 1and Bcl-2 proteins were significantly decreased(P＜0.05),Bcl-2/Bax ratio was significantly decreased(P＜0.05),and the mRNA levels of inflammatory cytokines,tumor necrosis factor-α and interleukin-6,were significantly up-regulated(P＜0.05).(2)Compared with the high-fat group,the above indexes were significantly improved in the aerobic exercise group(P＜0.05),while in the resistance exercise group,the body mass of mice was significantly decreased,the levels of inflammatory cytokines tumor necrosis factor-α and interleukin-6 mRNA were significantly decreased(P＜0.05),the protein expression of Caspase-3 was significantly decreased(P＜0.05),and the protein expression of brain-derived neurotrophic factor was significantly up-regulated(P＜0.05),but no significant changes were observed in the other indexes(P＞0.05).In conclusion,long-term exercise can reduce insulin resistance,down-regulate the expression of nuclear factor-κB pathway,weaken inflammatory response,inhibit neuronal apoptosis and improve synaptic plasticity,resulting in neuroprotective effects,and effectively alleviate obesity-related cognitive dysfunction in obese mice.The therapeutic effect of aerobic exercise is superior to that of resistance exercise.

ObjectiveTo observe the clinical efficacy and radiographic outcomes of manipulative reduction combined with small splint fixation in the treatment of distal radius fractures. MethodsThe clinical data of 1051 patients with distal radius fractures were retrospectively collected from five hospitals included in the Jiangsu Diagnosis and Treatment Data Platform for Traditional Chinese Medicine（TCM） Dominant Diseases. Propensity score matching at a 1∶4 ratio was applied， resulting in 580 cases selected for final analysis， which comprised 448 patients in the TCM group（manipulative reduction plus small splint fixation） and 132 in the surgical treatment group（open reduction and internal fixation）. Each group was further stratified into type A， B， and C subgroups based on AO fracture classification. Radiographic indicators including palmar tilt， radial inclination， and radial height were compared between groups before treatment and 1 day， 1 week， and 4-6 weeks after treatment， and pain visual analog scale（VAS） scores before treatment and 1 week and 4-6 weeks after treatment were also compared. Wrist joint function was assessed 12 weeks after treatment， using the Dienst wrist function score and the Gartland and Werley（G-W） wrist function score. Additionally， the radiographic indicators at different timepoints and the 12-week wrist function levels were compared between groups across different fracture types. ResultsNo statistically significant difference was observed in radiographic indicators and VAS scores at all timepoints before and after treatment， as well as wrist joint function grades assessed by the Dienst score and the G-W score at 12 weeks after treatment （P＞0.05）. Compared to those before treatment， both groups showed increased palmar tilt， radial inclination， and radial height 1 week and 4-6 weeks after treatment， and decreased VAS scores （P＜0.05）. Compared to those 1 week after treatment， both groups showed a decrease in palmar tilt， an increase in radial inclination and radial height， and a reduction in VAS score 4-6 weeks after treatment（P＜0.05）. In type A and B subgroups， the surgical treatment group had a higher radial inclination than the TCM group 4-6 weeks after treatment， while in the type C subgroup， a higher radial height was shown in the surgical treatment group than in the TCM group 4-6 weeks after treatment（P＜0.05）. In type C subgroup， there was significant difference between groups in the wrist joint function by G-W scores 12 weeks after treatment（P＜0.05）. ConclusionManipulative reduction combined with small splint fixation can maintain fracture alignment and alleviate pain in treating distal radius fractures， which achieves therapeutic outcomes comparable to surgical treatment. It is particularly suitable for type A and B fractures and can be considered an effective treatment option for distal radius fractures.

ObjectiveTo construct an automatic measurement model for palmar tilt and radial inclination suitable for traditional Chinese medicine （TCM） clinical scenarios， and to validate its accuracy and efficiency in TCM manipulative reduction settings. MethodsData on anteroposterior （AP） and lateral X-rays of distal radius fractures were collected from patients admitted to 18 TCM/ integrated TCM and western medicine hospitals in Jiangsu province between September 1st， 2023， and September 1st， 2024， via the Jiangsu Diagnosis and Treatment Big Data Platform for TCM Dominant Diseases. A medical image segmentation framework based on multi-scale feature fusion and edge-awareness was employed， combined with anatomical knowledge specific to TCM orthopedics， to optimize the feature extraction strategy of an artificial intelligence （AI） model. This framework enabled automatic segmentation of fracture regions and measurement of distal radius palmar tilt and radial inclination. The accuracy of the AI model in measuring radial inclination and volar tilt was validated， and the measurement time and average time gain rate of the AI model were compared to those of manual measurement. ResultsA total of 15,444 AP and lateral X-ray images of distal radius fractures were collected， and were divided into a training set （11,144 images， 5066 AP and 6078 lateral）， a validation set （3700 images， 1840 AP and 1860 lateral）， and an independent test set （600 images， 300 AP and 300 lateral） after preprocessing. In the measurement of 300 AP X-rays in the independent test set for radial inclination， when the degree error between AI measurement and manual measurement was ＜3° and ＜5°， AI measurement accuracy was 83% and 93%， respectively. In 300 lateral X-rays in the test set for palmar tilt， when AI measurements had an error of ＜3° and ＜5° compared to manual measurements， corresponding accuracy rate was 78% and 90%， respectively. For 50 X-ray images， AI measurement time was （1.37±0.05） min for radial inclination while manual measurement time was （22.57±2.52） min （P＜0.001）； in terms of palmar tilt， the AI measurement time was （1.33±0.14） min， shorter than （23.70±2.80） min for manual measurement time （P＜0.001）. Average time gain rates for manual and AI measurements were 93.93% and 94.39% respectively. ConclusionAn automatic measurement model for palmar tilt and radial inclination in distal radius fractures has been established， enabling more accurate and efficient assessment as well as providing a tool to support the quantitative evaluation of the efficacy of TCM manipulative reduction and large-sample clinical research.

Hyperthyroidism （HT） is frequently complicated by atrial fibrillation （AF） in clinical practice. Based on traditional Chinese medicine （TCM） zang-xiang （藏象） theory and clinical experience， both HT and AF are closely associated with dysfunction of the liver. The pathogenesis is initiated by the liver failing to govern the free flow of qi， and liver constraint and qi stagnation， with the key turning points being liver constraint transforming into fire and the internal stirring of liver wind， ultimately leading to liver blood depletion and insufficient nourishment of the heart spirit. Thus， it is proposed to treat the disease from the liver， with stage-specific therapeutic approaches according to the evolution of the disease. In the early stage， the treatment should focus on soothing the liver and relieving constraint to reduce goiter and calm the heart， while in the progressive stage， the method of clearing liver and draining fire is suggested to subdue yang and stabilize palpitations. In the acute stage， the strategy is calming the liver and nourishing yin to subdue yang and extinguish wind. In the later stage， it is suggested to soften the liver and benefit qi， so as to nourish yin and restore pulse. These methods are sequentially applied to synergistically reduce goiter and stabilize palpitations， providing a therapeutic approach for HT complicated by AF.

Objective To analyze the characteristics of intestinal flora of personnel stationed on an island,so as to lay the foundation for maintaining the intestinal microecological balance of personnel stationed on island and provide accurate medical security.Methods Several subjects stationed on an island and several subjects from coastal areas were enrolled by random and sampling method,and their fecal samples were sequenced by 16S rRNA high-throughput sequencing.Diversity and composition of gut microbiota in 2 cohorts of personnel were compared.Results Alpha diversity analysis of intestinal flora showed that the abundance of intestinal flora in subjects stationed on the island was significantly higher than that of subjects from coastal areas.Beta diversity analysis indicated significant differences in the composition of intestinal microbial communities between the subjects stationed on the island and those from coastal areas(P=0.001).The abundance of the Bacteroidota in the intestinal tract of subjects stationed on the island was significantly lower than that of subjects from coastal areas(30.8%vs 48.3%,P＜0.001),while the abundance of the Proteobacteria was significantly higher than that of subjects from coastal areas(28.3%vs 10.2%,P＜0.001).After multiple hypothesis testing correction,it was found that the abundance of the Bacteroides,Roseburia,Alistipes,and Parabacteroides in the intestines of subjects stationed on the island decreased significantly,while the abundance of the Prevotella,Escherichia-Shigella,Citrobacter,and Eubacterium_coprostanoligenes increased significantly.Conclusion The special environment of islands affects the characteristics of intestinal flora of personnel,and the intestinal microecological health needs precise maintenance.

Objective:To explore the effect of daglipzin combined with routine treatment on renal function, urinary podocyte-related protein (PCX) and inflammatory factors in patients with early diabetic kidney disease (DKD).Methods:A total of 120 early DKD patients in Baoji Traditional Chinese Medicine Hospital from March 2021 to December 2023 were prospectively collected and divided into two groups (observation group and control group) according to the random number table method, with 60 cases in each group. All patients received routine treatment. The observation group was additionally treated with daglipzin, while the control group was treated with metformin. Before and after treatment, the renal function indexes [vascular cell adhesion molecule-1 (VACM-1), creatinine (Cr), blood urea nitrogen (BUN)], urinary podocalyxin (PCX), and inflammatory factors [homocysteine (Hcy), high-sensitivity C-reactive protein (hs-CRP), macrophage migration inhibitory factor (MIF), tumor necrosis factor-α (TNF-α)] were detected in both groups. Meanwhile, the glucose metabolism levels [fasting blood glucose (FBG), glycosylated hemoglobin A 1c (HbA 1c)] and the occurrence of adverse reactions were compared between the two groups. Results:There were no significant differences in renal function, urinary PCX, glucose metabolism indexes, and inflammatory factor levels between the two groups before treatment (all P>0.05). After treatment, serum levels of VACM-1, BUN, Cr, hs-CRP, TNF-α, MIF, Hcy, FBG, HbA 1c, and urinary PCX in both groups were lower than those before treatment (all P<0.05). Moreover, the serum levels of VACM-1, BUN, Cr, hs-CRP, TNF-α, MIF, Hcy, FBG, HbA 1c, and urinary PCX in the observation group after treatment were lower than those in the control group (all P<0.05). There was no significant difference in the incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Compared with metformin, daglipzin combined with routine treatment can improve renal function, reduce urinary PCX and inflammatory factor levels in patients with early DKD, which has certain clinical application value.

Objective:To explore the value of blood lactic acid (BLA), procalcitonin (PCT), and total bilirubin (TBil) in the diagnosis and prognosis evaluation of patients with trauma complicated with sepsis.Methods:The clinical data of 151 patients with severe trauma admitted to the Department of Emergency Medicine, Nanxishan Hospital of Guangxi Zhuang Autonomous Region from July 2019 to August 2023 were analyzed retrospectively. The patients were divided into the sepsis group (72 cases) and non-sepsis group (79 cases) according to the diagnosis. They were further divided into the death group (37 cases) and non-death group (114 cases) based on clinical outcomes. Clinical data were compared between groups. Receiver operating characteristic (ROC) curve was used to analyze the predictive efficacy of the above indicators, and Spearman correlation analysis was applied to evaluate the correlation between the indicators.Results:The levels of BLA, PCT, TBil, and Sequential Organ Failure Assessment (SOFA) score in the sepsis group were higher than those in the non-sepsis group (all P<0.05). The mortality rate of the sepsis group was significantly higher than that of the non-sepsis group, with a statistically significant difference [26/72(36.11%) vs 11/79(13.92%), χ 2=10.024, P=0.002]. The levels of BLA, PCT, TBil, and SOFA score in the death group were higher than those in the non-death group (all P<0.05). ROC curve analysis showed that the areas under the curve (AUC) of BLA, PCT, TBil, and their combination for diagnosing sepsis were 0.745, 0.826, 0.753, and 0.889 respectively; the sensitivity and specificity of the combined diagnosis of sepsis were 87.5% and 72.2%. The AUCs of BLA, PCT, TBil, and their combination for predicting the prognosis of sepsis were 0.644, 0.697, 0.614, and 0.713 respectively; the sensitivity and specificity of the combined prediction of sepsis prognosis were 64.9% and 71.1%. Among the 151 patients, the levels of BLA, PCT, TBil were positively correlated with SOFA score, with statistically significant differences ( r=0.3871, 0.4399, 0.4851, all P<0.001). Conclusions:BLA, PCT, and TBil levels have certain value in the early diagnosis and prognosis evaluation of patients with sepsis. The combined evaluation has the best efficacy and high guiding value in clinical practice.
