The development of atherosclerosis （AS） is closely associated with endothelial dysfunction and mitochondrial metabolic abnormalities. These alterations are fundamentally characterized by metabolic reprogramming， in which the tricarboxylic acid （TCA） cycle serves as a central regulatory hub. Disruption of the homeostasis of TCA cycle intermediates， including succinate， α -ketoglutarate， and itaconate， contributes to AS progression through multiple mechanisms， such as the modulation of oxidative stress， inflammation， and glucose and lipid metabolic networks. Owing to their multi-target and multi-pathway regulatory properties， bioactive compounds derived from traditional Chinese medicine （TCM） have demonstrated unique advantages in correcting metabolic dysregulation. Flavonoids， glycosides， and other bioactive constituents of TCM can target key enzymes and metabolites involved in the TCA cycle， thereby restoring aberrant metabolic reprogramming， alleviating endothelial injury induced by oxidative stress， inflammation， and glucose and lipid metabolic disorders， ultimately improving metabolic homeostasis and attenuating the progression of AS.

Based on the modern understanding that lipid metabolism disorders mediate tumor microenvironmental imbalance in esophageal carcinoma， this paper proposes that failure of spleen and kidney warming and internal accumulation of phlegm-toxin constitute the core pathogenesis of esophageal carcinoma. Deficiency of spleen and kidney yang qi serves as the root cause， while impaired transformation and transportation of lipids and the accumulation of phlegm-toxin represent the superficial manifestations. Phlegm originates from the transformation of lipids， while toxin arises from and attaches to phlegm. Their interaction forms a sticky and persistent pathological state that runs throughout the entire disease process. The evolution of pathogenesis follows a dynamic and progressive pattern. In the early stage， failure of spleen and kidney warming and dysfunction of lipid metabolism mediate abnormalities in a lipid-enriched microenvironment； in the middle stage， lipid turbidity condenses into phlegm， and phlegm-toxin stasis promotes the formation of an inflammatory and hypercoagulable microenvironment； in the late stage， dysfunction of the sanjiao （三焦） warming function and impaired qi transformation lead to an imbalance in the hypoxic and metabolically dysfunctional microenvironment. Accordingly， a staged therapeutic approach is proposed， including warming the kidney and strengthening the spleen， transforming phlegm and resolving toxin， and warming and unblocking the sanjiao. By regulating lipid metabolism to restore tumor microenvironmental homeostasis， this approach provides a new theore-tical perspective and practical strategy for the intervention of esophageal cancer progression through traditional Chinese medicine.

Radiation enteritis(RE)is an inflammatory reaction caused by radiation exposure,commonly observed following radiotherapy for malignancies in the abdominal,pelvic and retroperitoneal regions.The authors believe that the pathogenesis of RE is complex,involving factors such as deficiency and excess,cold and heat,as well as qi and blood.The general pathogenesis can be summarized as"instability of the Zhongzhou,depletion of essence and blood,dysregulation of ascending and descending,and accumulation of heat-toxins".And"the instability of the Zhongzhou and subsequent malnutrition of the intestines"are the key drivers of disease progression.Based on theoretical exploration and clinical observations,this article proposed a comprehensive diagnostic and therapeutic approach centered on"stabilizing the Zhongzhou,replenishing essence and blood,regulating ascending and descending functions,and clearing heat-toxins".These four methods are often applied simultaneously,with"stabilizing the Zhongzhou and regulating the intestines"serving as the core of treatment.The approach is tailored according to the individual patient's condition of blood,qi and body fluids.A medical case was attached as evidence for verification.

Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room. In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Objective:To investigate the correlation between transabdominal bowel ultrasongraphy (TBUS) parameters and disease activity of ulcerative colitis (UC).Methods:The results of TBUS, endoscopy and laboratory tests of 68 UC patients (108 examinations) who visited the Department of Gastroenterology of the Second Hospital (Eastern Campus) of Hebei Medical University From January 2022 to February 2024 were retrospectively analyzed. According to Mayo endoscopic score (MES), there were 10 cases of remission (MES=0) and 98 cases of active phase (MES>0); patients in active phase further classified into 16 cases of mild (MES=1), 19 cases of moderate (MES=2), and 63 cases of severe (MES=3). The TAUS parameters were compared between patients in remission and active phases. Spearman rank correlation analysis was used to analyze the correlation between the TBUS parameters including bowel wall thickness (BWT), Limberg score, wall layer stratification, fat wrapping and endoscopic activity score, laboratory inflammatory indicators. Receiver operating characteristic curve (ROC) analysis was applied to evaluate the predictive efficacy of the TBUS parameters and laboratory inflammatory indicators in identifying remission under endoscopy. Independent sample t-test and Fisher′s exact probability method were used to compare the two groups. Results:The BWT of patients in remission was significantly thinner than that of patients in active phase ((2.99±0.41) mm vs. (5.66±1.57) mm, t=-5.34, P<0.001). The proportions of patients in remisson with Limberg score ≤2, normal wall layer stratification, and absence of fat wrapping were significantly higher than those of patients in active phase (10/10 vs. 34/98, 10/10 vs. 48/98, 10/10 vs. 41/98, Fisher′s exact test, P<0.001, =0.002, =0.001). BWT, Limberg score, wall layer stratification, and fat wrapping were positively correlated with MES ( r=0.676, 0.677, 0.441, and 0.493, all P<0.001). BWT and Limberg score were moderate positively correlated with C-hypersensitive reactive protein, erythrocyte sedimentation rate and fecal calprotectin (BWT: r=0.561, 0.420 and 0.458, all P<0.001; Limberg score: r=0.576, 0.469 and 0.403, all P<0.001), and were negatively correlated with serum albumin and hemoglobin (BWT: r=-0.604 and -0.453, both P<0.001; Limberg score: r=-0.573 and -0.532, both P<0.001). The results of ROC analysis showed that BWT achieved the best predictive efficacy in identifying endoscopic remission, and the best cut-off value was 3.45 mm (area under the curve was 0.972, 95% confidence interval: 0.944 to 1.000, P<0.001), with a sensitivity of 93.9% and specificity of 100.0%. Conclusions:TBUS parameters can accurately reflect disease activity in UC. It is a powerful tool for UC monitoring. The BWT<3.45 mm is the best cut-off value in prediction of endoscopic remission.

Objective To explore the role and mechanism of mechanically sensitive ion channel Piezo2 in mechanical allodynia of rats with low back pain induced by simulating the low-frequency vibration of a helicopter.Methods Low-frequency vibration(LFV)model with 3-dimensional 6 degrees of freedom was used to induce low back pain in awake rats in a sitting position.Twenty-four male SD rats(8 weeks old)were randomly divided into control(Ctrl)group and LFV group.HE staining was used to evaluate the injury of the multifidus muscle.Von Frey test was carried out to detect pain sensitivity.Open field test was employed to assess the spontaneous activity and anxiety.ELISA,Western blotting and immunofluorescence staining were performed to detect the expression of NGF,TrkA and downstream molecule Piezo2.Dorsal root ganglia(DRG)neurons was isolated from SD rats and primarily cultured.After identified with immunofluorescence staining,the neurons were divided into the Ctrl group,the LFV group,and the LFV+D-GsMTx4(D-G4,an Piezo2 channel antagonist)group.Western blotting was used to detect the protein expression of Piezo2,and a calcium ion fluorescent probe was utilized to detect the intracellular Ca2+.The DRG neurons were pretreated with 50 ng/mL NGF for 1 h.Calcium ion fluorescent probe was used to observe the changes in intracellular Ca2+in the LFV group,the LFV+NGF group,and the LFV+NGF+D-G4 group.Results The rats of the LFV group showed abnormal morphology in multifidus muscles,accompanied with inflammatory cell infiltration,decreased paw withdrawal reflex threshold(P<0.05),and shortened total active time and active time in the centre,and decreased distance traveled in the centre(P<0.05),while prolonged total stationary time,stationary time in the periphery,and increased distance traveled in the periphery(P<0.05),and moreover,enhanced expression of Piezo2,NGF and TrkA in the DRG tissues(P<0.05).Cell experiments showed that compared with the Ctrl group,the expression of Piezo2 in the neurons was increased(P<0.05),and the intracellular Ca2+level was significantly elevated in the LFV group(P<0.05).Compared with the LFV group,the Ca2+level was higher in the LFV+NGF group(P<0.05),and the sensitization effect of NGF on Piezo2 was reversed after D-G4 treatment(P<0.05).Conclusion Sustained low-frequency vibration induces low back pain and mechanical allodynia in rats through the NGF-TrkA/Piezo2 pathway.
