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.

Objective:To explore the optimization potential of clinical target volume (CTV) delineation proposed in the guidelines of the Oncology Group (RTOG), the Francophone Group of Urological Radiotherapy (GFRU), and the European Society for Radiotherapy and Oncology (ESTRO) based on prostate bed local occurrence patterns after radical prostatectomy identified using prostate-specific membrane antigen positron emission tomography (PSMA PET).Methods:A retrospective analysis was conducted on patients with local prostate bed recurrence after radical prostatectomy who underwent PSMA PET at the Department of Nuclear Medicine, Peking University First Hospital from September 2021 to February 2024. The central point of each recurrence was marked. A six-zone method was established based on prostate bed anatomy and the characteristics of cross-sectional imaging. Then, the positional relationships (within or outside) were recorded with respect to recurrences and CTV defined by the RTOG, GFRU, and ESTRO (CTV RTOG, CTV GFRU, and CTV ESTRO), followed the analysis of the recurrence rates and distribution characteristics of various zones. Results:A total of 63 patients with prostate bed recurrence after radical prostatectomy were enrolled in this study, including 97 recurrences. The recurrence rates in the six zones were as follows: 10% of zone 1, 22% of zone 2, 29% of zone 3, 2% of zone 4, 12% of zone 5a, 18% of zone 5b, and 7% of zone 6. Among these zones, zones 2 and 3 showed the highest and second-highest recurrence rates, respectively. CTV GFRU and CTV ESTRO completely covered zones 2 and 3, while CTV RTOG covered zone 2 completely and zone 3 partially. Zone 4, characterized by a low recurrence rate, was not covered by CTV GFRU and CTV ESTRO but was entirely covered by CTV RTOG. Zone 5a, with a recurrence rate of 12%, was completely covered by CTV RTOG but was partially covered by CTV GFRU and CTV ESTRO. The range of 1.3 cm in front of the posterior wall of the bladder covered all recurrences in zone 5a. Conclusions:For CTV delineation of the prostate cancer surgical bed, zone 4, the anterior half of the bladder above the pubic symphysis midpoint, should be contracted due to the low recurrence rate in this zone. In contrast, the anterior boundary above the pubic symphysis midpoint should extend to 1.3 cm in front of the posterior wall of the bladder to completely cover the recurrence zones.

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.

Opioid-induced constipation(OIC)is a typical complication in the treatment of cancer pain.Based on the origin of"removing the excess with lightness"and the principle of"removing the excess with lightness",this article proposed that qi blockade and heat toxicity are the core pathogenesis of OIC.It explored the effectiveness of the"removing the excess with lightness"method in treating OIC,seeking the unique characteristics of TCM inherent in the theory,aiming to offer new insights and approaches for the clinical treatment of this disease.

Objective:To analyze the incidence and influencing factors of lymphopenia in prostate cancer patients undergoing pelvic radiotherapy.Methods:A retrospective analysis was conducted on 123 prostate cancer patients treated at the Department of Radiation Oncology, Peking University First Hospital, from November 2011 to May 2015. Radiotherapy was administered using conventional fractionated intensity-modulated radiotherapy. Blood routine, including absolute lymphocyte count (ALC), was performed on patients before radiotherapy, weekly during radiotherapy, and at the end of radiotherapy. Severe lymphopenia was defined as an ALC <500 cells/μl. Based on whether the minimum ALC during radiotherapy was lower than 500 cells/μl, the entire cohort and 55 patients (excluding those with undelineated pelvic bone marrow due to radiotherapy planning system issues) with delineated pelvic bone marrow (divided into pelvic bone marrow, iliac bone marrow, and lower pelvic bone marrow) were stratified into a severe lymphopenia group (33 cases and 16 cases, respectively) and a mild lymphopenia group (90 cases and 39 cases, respectively). Differences in clinical factors and dosimetric parameters were compared between the groups using the chi-square test (or Fisher's exact test), t-test, and Wilcoxon rank-sum test. Univariate and multivariate logistic regression analyses were performed to identify the clinical and dosimetric factors influencing severe lymphopenia. Results:All 123 prostate cancer patients experienced lymphopenia during radiotherapy, with a median minimum ALC of 0.6×10 9/L [range: (0.2-2.3)×10 9/L]. Severe lymphopenia occurred in 26.8% (33 cases) of patients. Univariate analysis of the entire cohort showed that pre-radiotherapy baseline ALC, initial neutrophil-to-lymphocyte ratio, prostate-specific antigen value, Gleason score, and pelvic radiotherapy were promoting factors for severe lymphopenia ( P<0.05). Multivariate analysis identified pre-radiotherapy baseline ALC ( OR=0.217, 95% CI: 0.072-0.650, P=0.006) and pelvic radiotherapy ( OR=23.852, 95% CI: 2.834-200.787, P=0.004) as promoting factors for severe lymphopenia. In patients with delineated pelvic bone marrow, univariate analysis showed that pelvic bone marrow V 30 Gy and V 40 Gy, iliac bone marrow V 30 Gy and V 40 Gy, lower pelvic bone marrow V 30 Gy and V 40 Gy were promoting factors for severe lymphopenia during treatment ( P<0.05). Conclusions:Lymphopenia is common in prostate cancer patients undergoing radiotherapy, with a high incidence of severe lymphopenia. Pre-radiotherapy baseline ALC, as well as pelvic, iliac, and lower pelvic bone marrow V 30 Gy and V 40 Gy, are promoting factors for severe lymphopenia during radiotherapy.

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 chain mediating effect of coping style and illness perception between intolerance of uncertainty and fear of disease progression in patients with intracranial aneurysm.Methods:A total of 270 patients with intracranial aneurysms admitted to the neurosurgery department of 2 hospitals in Guangzhou from October 2023 to June 2024 were selected by convenience sampling method. The general information questionnaire, intolerance of uncertainty scale-12, the brief disease perception questionnaire, medical coping mode questionnaire(MCMQ) and fear of progression questionnaire-short form were used to investigate the subjects. Statistical description and Spearman correlation analysis were performed using IBM SPSS 25.0 software, and AMOS 23.0 software was used to test and correct the structural equation models.Results:The total score of fear of disease progression in patients with intracranial aneurysms was 27.50(20.00, 34.00). The total score of intolerance of uncertainty was 23.50(19.75, 29.00). The sores of confrontation, avoidance and submission in MCMQ were 18.69±5.44, 12.00(10.00, 15.00) and 7.00(5.00, 9.00), respectively.The total score of illness perception was 37.23±11.60. Fear of disease progression was positively correlated with intolerance of uncertainty, submission and illness perception ( r=0.614, 0.696, 0.680, all P<0.01). The direct effect of intolerance of uncertainty on fear of disease progression was significant in patients with intracranial aneurysms ( β=0.431, P<0.001). Intolerance of uncertainty indirectly affected fear of disease progression through submission ( β=0.181, P<0.001) and illness perception ( β=0.092, P<0.001). Submission and illness perception played chain-mediating effect in the relationship between intolerance of uncertainty and fear of disease progression ( β=0.103, P<0.001). Conclusion:The intolerance of uncertainty in patients with intracranial aneurysms can positively predict the fear of disease progression. Submission and illness perception played a chain mediating role between intolerance of uncertainty and fear of disease progression in patients with intracranial aneurysms.

Objective:To explore the mechanism of how neurocognition affects social functioning through fa-cial emotion recognition in individuals with schizophrenia.Methods:Totally 203 patients with schizophrenia meet-ing the Diagnostic and Statistical Manual of Mental Disorders,Fourth Edition(DSM-IV)diagnostic criteria were re-cruited,with an age of(40±12)years,an initial onset age of(24±8)years,scored(60.4±16.1)points on the Positive and Negative Syndrome Scale.Using the Personal and Social Performance Scale(PSP),the MATRICS Consensus Cognitive Battery(MCCB),and the Facial Emotion Recognition Test(FERT)to assess patients'social functioning,neurocognition,and facial emotion recognition abilities.Results:In the relationship between MCCB fac-tor scores and PSP dimensions scores,happy face recognition showed a mediating effect in socially useful activities dimension(ACME=0.021,P＜0.01),sad(ACME=-0.026,P＜0.05)and surprised face recognition(ACME=-0.017,P＜0.05)showed mediating effects in self-care dimension.Additionally,sad(ACME=-0.025,P＜0.05)and fearful face recognition(ACME=-0.025,P＜0.001)played a mediating role in disruptive and aggres-sive behavior dimensions.Conclusion:Facial emotion recognition in patients with schizophrenia may play a media-ting role in the neurocognitive mechanisms of social dysfunction,with different dimensions of social dysfunction be-ing associated with specific categories of emotions.
