This paper summarizes the experience of professor LIU Shangyi in differentiating and treating rectal carcinoma from the perspective of "treating ulcers as tumors". It is believed that the manifestations of rectal cancer， such as anal itching， cauliflower-like or ulcerative tumors， and bloody stools， are similar to external skin itching， skin ulceration， swelling， and skin bleeding. Therefore， the treatment principles of sores and ulcers department can be applied to treat tumors. Following the diagnostic and treatment approach of dermatology regarding the clinical typical symptoms， for anal itching， the main treatment is to dispel wind and remove dampness， clear heat to relieve itching， using "skin medicinals" such as Difuzi （Fructus Kochiae） and Baixianpi （Cortex Dictamni）， as well as wind medicinals such as Shengma （Rhizoma Cimicifugae） and Fangfeng （Radix Saposhnikoviae）. For constipation， the method of clearing heat and resolving toxins， unblocking the bowels and discharging heat can be used， commonly using Baitouweng （Radix Pulsatillae）， Donglingcao （Herba Rabdosiae Rubescentis） and Dahuang （Radix et Rhizoma Rhei）. In terms of mucosal ulcers， it is critical to differentiate between yin and yang； the treatment of yang ulcers should focus on clearing heat and resolving toxins， commonly using modified Xianfang Huoming Beverage （仙方活命饮）； for yin ulcers， emphasis should be placed on removing dampness and resolving phlegm， commonly with modified Yiyi Fuzi Baijiang Powder （薏苡附子败酱散）. For bloody stool， differentiation is made between deficiency and excess， with the use of Diyu （Radix Sanguisorbae） and Huaihua （Flos Sophorae） for excess syndrome to cool and stop blee-ding， and both herbs dry-fried until charred combined with liver-tonifying medicinals for deficiency syndrome

arcopenia is a systemic skeletal muscle disorder characterized by a decrease in skeletal muscle mass and progressive decline in function， with multiple signaling pathways involved in its occurrence and development. Among them， the AMP-activated protein kinase （AMPK） signaling pathway， as a key pathway regulating cellular energy homeostasis， plays an important role in the regulation of skeletal muscle metabolism and functional maintenance by improving abnormalities in glucose and lipid metabolism， balancing skeletal muscle protein synthesis and degradation， improving mitochondrial function， promoting autophagy， and inhibiting inflammatory responses and oxidative stress. This article reviews the research progress on how various traditional Chinese medicine （TCM） monomers， including polyphenols， flavonoids， and terpenoids； various traditional Chinese medicine extracts， such as those from Lycium barbarum ， Asini Corii Colla， and Panax quinquefolium ， and TCM compounds， such as Guiqi zhuangjin decoction， Jianpi qiangji granules， and Qigu capsules， intervene in sarcopenia by regulating the AMPK signaling pathway to promote muscle protein synthesis， inhibit protein degradation， improve mitochondrial function， and alleviate inflammation and oxidative stress. Additionally， their molecular mechanisms are explored. The aim is to deeply elucidate the basis of TCM in the prevention and treatment of sarcopenia and to provide theoretical support for the development of related innovative drugs.

This paper explores the immune-inflammatory regulatory mechanism of colorectal cancer cachexia and corresponding traditional Chinese medicine （TCM） intervention strategies based on the TCM theory of reinforcing healthy qi and dispelling pathogenen. It is proposed that depletion of healthy qi is the root cause of colorectal cancer cachexia， while cancer toxins exuberance is the symptomatic manifestation of the disease， and failure of the spleen and stomach is the core pathogenesis. In terms of treatment， a TCM treatment system is constructed based on the principles of reinforcing healthy qi to consolidate the foundation and regulate immunity， and dispelling pathogen to remove toxins and alleviate inflammation. The system clarifies the healty qi-reinforcing method as fortifying spleen and boosting qi to enhance immune function， and nourishing blood and enriching yin to consolidate yin essence and healthy qi. It also emphasizes the pathogen-dispelling method as clearing heat and removing toxins to regulate the secretion of inflammatory cytokines， and promoting blood circulation and resolving stasis to improve the immune microenvironment and microcirculation. This therapeutic approach may provide valuable insights for TCM interventions in colo-rectal cancer cachexia.

Objective:To explore the genetic and clinical characteristics of Guizhou patients with enlarged vestibular aqueduct（EVA） syndrome through combined SLC26A4 variant analysis and clinical phenotype analysis. Methods:Seventy-two EVA patients underwent comprehensive genetic testing using a multiplex PCR-based deafness gene panel and next-generation sequencing（NGS）. The audiological and temporal bone imaging characteristics were compared across mutation subtypes. Results:A total of 27 pathogenic loci of SLC26A4 were detected in 72 patients, including c.919-2A>G in 79.2%（57/72）. A novel deletion（c.1703_1707+6del） was discovered. Among 65 cases, truncated mutations were 89.2%（58/65）, 52.3%（34/65）, 28（43.1%） and 7（10.8%）. No significant differences were observed in the midpoint diameter of the vestibular aqueduct and the incidence of incomplete partitioning typeⅡ（IP-Ⅱ） of the cochlea among the three groups of patients. Moreover, there was no difference in the midpoint diameter of different vestibular pipes or the combination with IP-Ⅱ. Conclusion:The most common mutation site of SLC26A4 in EVA patients in Guizhou is c.919-2A>G, though genotype-phenotype correlations remain elusive. The detection of 27 mutation sites and the discovery of new mutation sites suggested the precise diagnostic significance of NGS technology in EVA patients in Guizhou.

Approximately 30%-40% of epilepsy patients do not respond well to adequate anti-seizure medications (ASMs), a condition known as pharmacoresistant epilepsy. The management of pharmacoresistant epilepsy remains an intractable issue in the clinic. Its early prediction is important for prevention and diagnosis. However, it still lacks effective predictors and approaches. Here, a classical model of pharmacoresistant temporal lobe epilepsy (TLE) was established to screen pharmacoresistant and pharmaco-responsive individuals by applying phenytoin to amygdaloid-kindled rats. Ictal electroencephalograms (EEGs) recorded before phenytoin treatment were analyzed. Based on ictal EEGs from pharmacoresistant and pharmaco-responsive rats, a convolutional neural network predictive model was constructed to predict pharmacoresistance, and achieved 78% prediction accuracy. We further found the ictal EEGs from pharmacoresistant rats have a lower gamma-band power, which was verified in seizure EEGs from pharmacoresistant TLE patients. Prospectively, therapies targeting the subiculum in those predicted as "pharmacoresistant" individual rats significantly reduced the subsequent occurrence of pharmacoresistance. These results demonstrate a new methodology to predict whether TLE individuals become resistant to ASMs in a classic pharmacoresistant TLE model. This may be of translational importance for the precise management of pharmacoresistant TLE.

Lipid turbidity disease is a metabolic disease featuring lipid metabolism disorders caused by many factors such as social environment， diet， and lifestyle， which is closely related to many diseases in modern medicine， such as hyperlipidemia， obesity， fatty liver， atherosclerosis， metabolic syndrome， and cardiovascular and cerebrovascular diseases， with a wide range of influence and far-reaching harm. According to the Huangdi Neijing， lipid turbidity disease reflects the pathological change of the body's physiologic grease. Grease is the thick part of body fluids， which has the function of nourishing， and it is the initial state and source of important substances in the human body such as brain， marrow， essence， and blood. Once the grease of the human body is abnormal， it can lead to lipid turbidity disease. The Huangdi Neijing also points out the physiological relationship between the transportation and transformation of body fluids and the rise and fall of the spleen and stomach， which can deduce the pathological relationship between the occurrence of lipid turbidity disease and the abnormal rise and fall of the spleen and stomach functions. Lipid turbidity disease is caused by overconsumption of fatty and sweet foods or insufficient spleen and stomach endowments， leading to disorders of the function of promoting clear and reducing turbidity in the spleen and stomach. This leads to the transformation of thick grease in body fluids into lipid turbidity， which accumulates in the body's meridians， blood vessels， skin pores， and organs， forming various forms of metabolic diseases. The research team believed that the pathological basis of lipid turbidity disease was the abnormal rise and fall of the spleen and stomach and the obstruction of the transfer of grease. According to the different locations where lipid turbidity stays， it was divided into four common pathogenesis types： ''inability to distinguish between the clear and turbid， turbid stagnation in the Ying blood''， ''spleen not rising clear， turbid accumulation in the vessels''， ''spleen dysfunction， lipid retention in the pores''， ''spleen failure to transportation and transformation， and grease accumulation in the liver''. According to the pathogenesis， it could be divided into four common syndromes， namely， turbid stagnation in the Ying blood， turbid accumulation in the vessels， lipid retention in the pores， and grease accumulation in the liver， and the corresponding prescriptions were given for syndrome differentiation and treatment， so as to guide clinical differentiation and treatment of the lipid turbidity disease.

Objective To investigate the effects of 20%mannitol injection on the proliferation and apoptosis of hu-man lung squamous carcinoma cell line NCI-H292 and its possible mechanisms.Methods NCI-H292 cells were incubated with 20%and lower concentrations of mannitol.Cell proliferation and viability were detected by CCK-8 assay.Cell apoptosis was detected by flow cytometry and the expression of mitochondrial apoptosis pathway-related proteins Bcl-2 and Bax was detected by Western blot.Results Compared with the control group,mannitol inhibited cell proliferation in a dose-and time-dependent manner(P＜0.05),20%mannitol could induce cell ap-optosis(P＜0.05).The expression level of Bcl-2 was significantly reduced,while that expression level of Bax was significantly increased in cells incubated with 20%mannitol(P＜0.05).Conclusions Clinically used 20%man-nitol injection can induce apoptosis of lung squamous carcinoma cell line NCI-H292.Its mechanism is related to mi-tochondrial pathway-related proteins Bcl-2 and Bax.

Objective:To establish a method to detect IDH2 gene mutations in the cell-free DNA (cfDNA) sample of angioimmunoblastic T-cell lymphoma (AITL) based on the digital droplet PCR (ddPCR) method. The performance of this method was evaluated.Methods:Specific primers and probes were designed for IDH2 p. R172K, IDH2 p. R172M, and IDH2 p. R172W mutations, and primer combinations were optimized to establish the optimal ddPCR reaction system. In addition, the accuracy, precision, specificity, and detection limit of the method were evaluated using clinical cfDNA samples obtained from 40 patients with AITL at the First Affiliated Hospital of Nanjing Medical University.Results:The IDH2 R172K/M/W F2/R2 primer combination was selected to establish the ddPCR detection method for IDH2 R172K/M/W mutations. Specific standard samples showed no false-positive results. The accuracy test revealed that the relative deviation of the standard sample measurements was within ±10%. The detection limit test indicated that the method could detect 1 ng/μl with a 0.2% mutation rate for IDH2 R172K/M/W mutations. The precision measurements (inter-experimenter, inter-run, and inter-laboratory) all had a coefficient of variation of <5%. ddPCR was applied to 40 clinical samples with IDH2 R172K/M/W mutations, and the results were fully consistent with gene sequencing.Conclusion:ddPCR can detect IDH2 gene mutations in cfDNA from AITL with high sensitivity, specificity, and absolute quantification. This method offers a simple, rapid, and reliable approach for diagnosing and monitoring.

Objective:To investigate the impact of perceived barriers to cardiac rehabilitation on adherence to cardiac rehabilitation and the mediating effect of cardiac impact denial in elderly patients after percutaneous coronary intervention (PCI) .Methods:This study was a cross-sectional survey. From August 2023 to July 2024, 336 elderly patients with PCI who were discharged from the First Affiliated Hospital of Wenzhou Medical University and needed phaseⅡ cardiac rehabilitation were selected for the study. General Information Questionnaire, Adherence of Cardiac Rehabilitation Assessment Scale in Patients with Coronary Heart Disease (ACRAS-CHD) , Cardiac Rehabilitation Barriers Scale (CRBS) , and Cardiac Denial of Impact Scale (CDIS) were used to survey the patients. Bootstrap method was used to sample 5 000 for mediating effect tests.Results:A total of 336 questionnaires were distributed and 324 valid questionnaires were recovered, with a valid recovery rate of 96.43% (324/336) . Among 324 elderly patients after PCI, ACRAS-CHD score, CRBS score, and CDIS score were (73.19±5.46) , (79.35±6.60) , and (30.57±3.66) , respectively. The direct effect of perceived barriers to cardiac rehabilitation on adherence to cardiac rehabilitation in elderly patients after PCI was -0.368, which accounted for 74.49% (-0.368/-0.494) of the total effect. The mediating effect of cardiac impact denial between perceived barriers to cardiac rehabilitation and adherence to cardiac rehabilitation in elderly patients after PCI was -0.126, which accounted for 25.51% of the total effect (-0.126/-0.494) .Conclusions:Elderly patients after PCI have poor adherence to cardiac rehabilitation. Perceived cardiac rehabilitation barriers reduce cardiac rehabilitation adherence in elderly patients after PCI, and cardiac impact denial exerts a partial mediating effect between perceived cardiac rehabilitation barriers and cardiac rehabilitation adherence.
