ObjectiveThis paper aims to explore the risk factors for chronic atrophic gastritis （CAG） with turbidity toxin accumulation syndrome and establish a prediction model. MethodsClinical data of 180 patients with CAG who participated in the "clinical study of Xianglian Huazhuo Particles blocking CAG cancer transformation" of Hebei Sheng Zhong Yi Yuan from July 2021 to March 2022 were collected. After confounding factors were controlled by propensity score matching， patients were divided into a training set （namely dev） and a validation set （namely vad） in a seven to three ratio. The risk factors for CAG with turbidity toxin accumulation syndrome in the training set were investigated by using univariate Logistic regression analysis and least absolute shrinkage and selection operator （namely Lasso） regression algorithms. Subsequently， a model， named model 1se， was developed by using the training set data to predict the risk factors for CAG with turbidity toxin accumulation syndrome. The accuracy of the prediction model was assessed by using various methods， including the receiver operating characteristic （ROC） curve， Hosmer-Lemeshow test （H-L）， calibration plot， and decision curve analysis （DCA）. ResultsAge， body mass index （BMI）， family history of cancer， job and life satisfaction， yellow and greasy fur with slippery pulse， and heavy body sensation were independent risk factors of the model. The prediction model showed excellent predictive value for both the training and validation sets. ConclusionThe established prediction model for CAG with turbidity toxin accumulation syndrome has high discrimination and excellent calibration， which could provide an excellent clinical basis for disease diagnosis and individualized treatment of patients.

ObjectiveTo construct a scale for the diagnosis of chronic atrophic gastritis （CAG） with turbid toxin accumulating in the stomach. MethodsFirst， a research group was established to construct the scale framework. Relevant literature of CAG with syndrome of turbid toxin accumulating in the stomach was searched in CNKI， Wanfang Database （WF）， and VIP Database （CQVIP） from April 1， 2003 to April 1， 2023， and items were preliminarily selected after standardization of terms. Through clinical investigation， the discrete trend method， correlation coefficient method， Cronbach's coefficient method， and factor analysis method were used to screen symptom items， and the frequency method was used to screen signs， tongue coating， and pulse conditions. Three rounds of Delphi expert consultation were conducted to determine the items of the scale. The weight of each item was obtained by the analytic hierarchy process. ResultsA total of 49 articles were included， and 45 items were obtained after primary screening， including 28 symptoms， 2 signs， 10 tongue coatings， and 5 pulse conditions. After clinical investigation， 15 symptoms were retained， and 8 signs and pulse conditions of tongue coating were retained. The positive coefficients of experts in three rounds of Delphi expert consultation were 100%， 96.67%， and 100%， respectively. The expert authority coefficients were 0.86， 0.87， and 0.87， respectively， and the coordination coefficients were 0.18， 0.25， and 0.30. After core group discussion， Delphi method investigation， and AHP weight assignment， the diagnostic scale items of CAG with turbid toxin accumulating in stomach syndrome were finally established， namely， dark red or purplish tongue proper with yellow greasy （or dry） coating （30 points）， epigastric stuffiness and fullness or pain （15 points）， sticky and unsmooth defecation （10 points）， taste disturbance （sticky mouth， fetid breath， bitter taste， 7 points）， heartburn or acid regurgitation （6 points）， dizziness and clouding （5 points）， general heaviness and fatigue （5 points）， slippery， string‑slippery， or slippery‑rapid pulse （5 points）， dysuria （or yellow or deep yellow urine， 4 points）， poor appetite （4 points）， dull complexion （3 points）， sticky， greasy， and fetid secretions （3 points）， and poor sleep （3 points）. ConclusionBased on the establishment， screening， confirmation， and weighting of an item pool， combined with subjective and objective approaches as well as qualitative and quantitative methods， a diagnostic scale for CAG with the syndrome of turbid toxin accumulating in the stomach was successfully constructed.

In the current era where digital technology is reshaping the cultural communication ecology， the cultural cognition mode in human society is undergoing a profound transformation from a text-centric to a visually-centric approach. Knowledge visualization， as a crucial force driving this transformation， is systematically propelling the transition of traditional Chinese Medicine （TCM） culture from an “empirical paradigm” to a “visualized paradigm.” From multidimensional perspectives such as cultural studies， linguistics， and phenomenology， this paper analyzed the theoretical foundation for the integration of knowledge visualization and the inheritance of TCM culture， and addressed the contemporary dilemmas in traditional mentor-apprentice models， classic text dissemination， and linear inheritance. On this basis， it proposed three concrete paths for transforming the inheritance methods of TCM culture under the trend of knowledge visualization. These included shifting from the “experience-oriented” mentor-apprentice inheritance to the narrative construction of “visual culture，” from the “rationalist” cultural recognition to the value identification of “integration of reason and emotion，” and from the cultural inheritance of “linear knowledge” to the systematic inheritance of “mind mapping.” Collectively， this study provides theoretical and practical references for the creative transformation and innovative development of TCM culture.

ObjectiveTo observe the effectiveness and safety of Jiuzihuichun decoction combined with spleen- strengthening moxibustion in patients with asthenospermia infertility with spleen-kidney deficiency pattern. MethodsA total of 82 patients with asthenospermia of spleen-kidney deficiency pattern in Shanghai Seventh People's Hospital were included. The patients were randomly divided into an observation group and a control group， with 41 patients in each group. The control group received oral administration of WuziYanzong pills combined with spleen-strengthening moxibustion. The dosage of Wuzi Yanzong pills was 1 bag each time， and it was taken twice a day. The spleen-strengthening moxibustion was carried out once a week. The observation group， on the other hand， took Jiuzi Huichun decoction orally combined with spleen-strengthening moxibustion. The Jiuzi Huichun Decoction was taken 200 mL each time， twice a day， with one dose in the morning and one in the evening. The spleen-strengthening moxibustion for the observation group was also performed once a week. The treatment course for both groups was 12 weeks， and they were followed up for an additional 12 weeks. During the treatment process，12 cases were either lost to follow-up or excluded. Eventually， 70 cases were available for evaluation，with 35 cases in the control group and 35 cases in the observation group. The pregnancy status of the patients' spouse within 6 months was recorded. The traditional Chinese medicine （TCM） syndrome scores of spleen-kidney deficiency pattern before and after treatment were evaluated. The semen volume，semen routine parameters，normal sperm morphology，sperm DNA fragmentation index，seminal plasma fructose，seminal plasma acid phosphatase， and seminal plasma α-glucosidase levels of the two groups were detected before and after treatment. In addition， the safety indicators related to liver and kidney functions of the two groups were detected before and after treatment. ResultsDuring the 6-month observation period， when compared with the situation before treatment in their respective groups，the semen volume of the observation group and the control group increased. In contrast， the sperm concentration，sperm motility，proportion of a+b-grade sperm，normal sperm morphology，seminal plasma fructose，seminal plasma acid phosphatase，seminal plasma α-Glucosidase，the proportion of a-grade sperm，linear sperm motility，linear sperm concentration， and linear sperm count all increased significantly（P<0.05）. At the same time， the sperm DNA fragmentation index and the TCM syndrome scores of the spleen-kidney deficiency pattern decreased significantly（P<0.05）. When the observation group was compared with the control group after treatment， the clinical efficacy of the observation group was better（Z=-2.276，P<0.05）. The pregnancy rate of the observation group's spouses was 14.3%，which was higher than the 2.9% of the control group. The sperm motility， the proportion of a+b-grade sperm，seminal plasma fructose，the proportion of a-grade sperm，normal sperm morphology，α-glucosidase， and linear sperm motility in the observation group were higher than those in the control group （P<0.05）. Moreover， the sperm DNA fragmentation index and the TCM syndrome scores of spleen-kidney deficiency pattern in the observation group were lower than those in the control group （P<0.01）. No serious adverse reactions occurred in the two groups，and no abnormalities were found in the safety indicators after treatment. ConclusionJiuzi Huichun decoction combined with spleen-strengthening moxibustion can enhance sperm viability and sperm concentration. It can also improve the TCM-related symptoms of asthenospermia of spleen-kidney deficiency pattern and sperm morphology. Additionally， it can reduce the sperm DNA fragmentation index and regulate the level of seminal plasma bioenzyme in patients with male asthenospermia infertility of spleen-kidney deficiency pattern. Therefore， it is worthy of further promotion and application in clinical practice.

Dendrobium is the largest genus of the Orchidaceae family.The fresh and dried stems of many species of this genus have been used as Shihu(Dendrobii Caulis)in traditional Chinese medicine,it is known as the foremost of the"Nine Great Herbs of China".Ancient texts highlight its uses for"strengthening yin,enhancing essence,nourishing the five viscera,alleviating fatigue,and dispelling skin heat and prickly heat".Modern research confirms that the polysaccharides and alkaloids it contains have antiviral ef-fects,it can apply in treating immunodeficiency caused by viral infections clinically.While studies are gradually uncovering the antivi-ral mechanisms and material basis of Dendrobium,the lack of systematic analysis and organization has hindered its resource develop-ment.The paper employed CiteSpace software for bibliometric analysis of Chinese and English literature on Dendrobium.It reviewed the herbalism,material basis,and mechanisms of its antiviral properties building upon the systematic review of ancient materia medica and modern literature.Results indicate that Dendrobium can boost vital energy and resist pathogens,showing great potential in antiviral drug development.

Gallbladder cancer is the most common malignant tumor of the biliary system,characterized by insidious growth,rapid progression,and skip metastasis.The 5-year overall survival rate is only 5%.Although targeted immunotherapies have emerged in recent years,they are still in the exploratory phase for the treatment of gallbladder cancer,and radical surgical resection remains the only potentially curative treatment.The main goal of surgery is to completely remove the tumor and perform systematic lymph node dissection to reduce the risk of recurrence.Thanks to advances in surgical techniques and continuous optimization of perioperative management,postoperative complications,and hospital mortality in patients undergoing extended radical surgery for gallbladder cancer have decreased.However,the complex mechanisms of gallbladder cancer spread and metastasis make it challenging to determine the optimal scope of surgical resection.Clinical guidelines from different countries and hepatobiliary surgery centers often vary on surgical options,especially regarding the reasonable extent of liver resection,the scope of lymph node dissection and its impact on prognosis,and whether routine extrahepatic bile duct resection should be performed.There remains significant controversy in these areas.Future extensive prospective cohort studies are still needed to provide more evidence-based medical data for the surgical treatment of gallbladder cancer.When designing a surgical plan,surgeons must consider preoperative examination results,intraoperative findings,and pathological evaluation of frozen sections.A balance must be struck between radical treatment and safety and effectiveness.The most appropriate surgical method for each patient should be chosen while also emphasizing establishing a multidisciplinary collaborative system.Based on accurate tumor staging,postoperative adjuvant therapies should be integrated to continue making progress in improving patient prognosis.

Objective:To explore the impact of diabetes mellitus on perioperative myocardial injury and cardiac function recovery in patients undergoing off-pump coronary artery bypass grafting (CABG).Methods:The clinical data of 40 patients with coronary heart disease who underwent off-pump CABG in Changsha Central Hospital from 2015 to 2025 were retrospectively included. They were divided into the diabetes group (20 cases) and the control group (20 cases) according to whether they had type 2 diabetes mellitus. Myocardial injury markers (creatine kinase isoenzyme, troponin I, lactate dehydrogenase) before surgery, on the 1st and 3rd days after surgery and before discharge, as well as cardiac function indicators (B-type natriuretic peptide, left ventricular ejection fraction) before surgery and before discharge were compared between the two groups. The postoperative recovery speed (mechanical ventilation time, intensive care unit stay, vasoactive drug use time, postoperative hospital stay) was also compared between the two groups.Results:Before surgery, there were no statistically significant differences in myocardial injury markers and cardiac function indicators between the two groups (all P>0.05). On the 3rd day after surgery, lactate dehydrogenase in the diabetes group was significantly higher than that in the control group ( P<0.05), while there were no statistically significant differences in creatine kinase isoenzyme and troponin I between the two groups (all P>0.05). Before discharge, the levels of creatine kinase isoenzyme and B-type natriuretic peptide in the diabetes group were significantly higher than those in the control group (all P<0.05), and the left ventricular ejection fraction was significantly lower than that in the control group ( P<0.05). Compared with the control group, the diabetes group had significantly longer mechanical ventilation time, intensive care unit stay, and postoperative hospital stay (all P<0.05), but there was no statistically significant difference in the use time of vasoactive drugs ( P>0.05). Conclusions:For patients with coronary heart disease complicated with diabetes mellitus, their preoperative cardiac status is comparable to that of patients without diabetes mellitus, but they show a characteristic dynamic injury pattern after surgery: early elevation of lactate dehydrogenase suggests susceptibility to subcellular injury, and long-term abnormalities of creatine kinase isoenzyme, B-type natriuretic peptide, and decrease in left ventricular ejection fraction indicate myocardial repair disorders. Compared with patients without diabetes mellitus, those with diabetes mellitus require a longer recovery time after off-pump CABG, and targeted perioperative management strategies are urgently needed.

AIM:To investigate the immunosuppressive effects of M2-like tumor-associated macrophages(M2-TAMs)on CD8+T cells within the tumor microenvironment of esophageal cancer.METHODS:Multiplex fluores-cence immunohistochemistry was used to analyze the distribution of immune cells in esophageal cancer tissues.An in vitro co-culture system was established,and flow cytometry along with Calcein-AM/PI staining was employed to assess the im-pact of M2-TAMs on CD8+T cell function.The GEPIA database was utilized to evaluate the prognostic significance of PDCD1 expression in esophageal cancer patients and to analyze the correlations between gene expressions.Immunohisto-chemistry(IHC)was performed to detect the expression of TGF-β1 in esophageal cancer tissues.Flow cytometry and en-zyme-linked immunosorbent assay(ELISA)were used to measure PD-1,IFN-γ and TNF-α expression in CD8+T cells fol-lowing treatment with a TGF-β1 inhibitor.RESULTS:Compared with early-stage(stage I)esophageal cancer patients,the patients with advanced disease(stages Ⅱ to Ⅳ)exhibited dynamic changes in the infiltration of CD4+T cells,CD8+T cells,Tregs,and M2-TAMs within tumor tissues,with significant correlations observed among these cell populations(P<0.05).The distribution of M2-TAMs and Tregs was positively correlated with poor prognosis(P<0.05),while that of CD8+T cells was negatively correlated(P<0.05).In contrast,CD4+T cell infiltration showed no significant association with clinical outcomes(P>0.05).Co-culture of CD8+T cells with M2-TAMs resulted in significant downregulation of CD107a,granzyme B,IFN-γ and TNF-α expression(P<0.01).Additionally,M2-TAM-treated CD8+T cells co-cultured with esophageal cancer cells led to reduced apoptosis of cancer cells.High expression of PDCD1 was significantly associated with poor prognosis(P<0.05),and significant correlations were observed between CD8A and PDCD1 expression,as well as between TGF-β1 and CD274 gene expression(P<0.01).TGF-β1 was also significantly associated with CD163+macro-phage infiltration and the progression of esophageal cancer(P<0.05).Treatment with a TGF-β1 inhibitor in the M2-TAM and CD8+T cell co-culture system significantly down-regulated PD-1 expression and increased the secretion of IFN-γ and TNF-α(P<0.01).CONCLUSION:The TGF-β1 derived from M2-TAMs inhibits the antitumor activity of CD8+T cells in the esophageal cancer microenvironment,suggesting potential therapeutic targets for overcoming immunosuppression in esophageal cancer.

Cholangiocarcinoma(CCA)is a highly malignant digestive system tumor with strong invasiveness and difficulty in treatment.Its high drug resistance,difficulty in early diagnosis,and rapid progression of invasion and metastasis pose signifi-cant challenges to clinical treatment.Research has shown that the development of resistance in CCA is one of the key factors in-fluencing treatment outcomes,with non-genetic factors playing a crucial role in the resistance process.This article summarizes the non-genetic factors contributing to resistance in CCA,and discusses the roles of epigenetic heterogeneity,epigenetic plastici-ty,and the tumor microenvironment in mediating resistance in CCA.The goal is to provide new theoretical insights for overco-ming treatment resistance in CCA.
