Investigator initiated trial （IIT） represents a primary format for clinical research in traditional Chinese medicine （TCM）. As key implementation sites for TCM-based IIT targeting malignant tumors， western medicine institutions often face unique challenges in conducting such studies， which limit their feasibility and standardization. This paper reviews the registration status of TCM-based IIT for malignancies conducted in western medical institutions and analyzes key difficulties， including complex project initiation and management processes， limited TCM knowledge and skills among western medicine physicians， and relatively low patient acceptance of TCM. From a practical perspective， the study proposes several optimization strategies. These include improving the review and management mechanisms of TCM-related IIT within western medical institutions， establishing multidisciplinary clinical research teams that integrate TCM and western medicine， and enhancing investigators' training in TCM theory and clinical skills. Additionally， the study suggests standardizing IIT operational procedures， objectifying the collection of TCM diagnostic information， refining subject recruitment methods， and increasing TCM involvement in patient follow-up and management. These investigator-oriented， TCM-featured， and operable strategies aim to promote the high-quality development of TCM-based IIT in western medicine institutions and enhance the clinical application of TCM.

According to the theory of cancer toxin pathogenesis， tumors are complex syndromes centered on cancer toxin， characterized by multiple time points and locations， interwoven pathogenic toxins， and a combination of deficiency and excess. Postoperative recurrence of colorectal cancer is a dynamic spatiotemporal process. In this paper， the core pathogenesis of postoperative recurrence of colorectal cancer， namely "deficiency of spleen qi， with damp-heat stasis toxin"， has been discussed based on spatiotemporal evolution of cancer toxin. It is suggested that spleen qi depletion leading to the proliferation of cancer toxin represents the temporal characteristic of postoperative recurrence， while the stasis of damp-heat facilitating the aggregation and spread of cancer toxin refelct its spatial pattern. This paper has constructed a holistic spatiotemporal prevention and treatment strategy according to different stages before and after recurrence. Before recurrence， the focus is on prevention， and it is suggested to rectify the healthy qi and fortify spleen， clear heat and resolve dampness， unblock collaterals and remove toxin. After recurrence， the focus should be on treatment， and the strategy is combating cancer and removing toxin， breaking the blood to eliminate disease， regulating and tonifying the zang-fu （脏腑） organs.

Objective:To analyze the current status of clinical research registration on TCM prevention and treatment of malignant tumors in the Chinese Clinical Trail Registry (ChiCTR); To summarize its characteristics and shortcomings.Methods:Clinical studies on the TCM prevention and treatment for malignant tumors registered from the establishment of ChiCTR database to July 15, 2024 were retrieved. Excel 2019 software was used to sort out the data, including basic research information (registration time, registration number status, registration title, test organizer, research implementation location, etc.), design scheme (disease type, research type, intervention measures, sample size, blind method, etc.), research funding or material sources, as well as other information such as human specimen collection and recruitment of research objects. SPSS 27.0 software was used for frequency statistics.Results:A total of 891 registered studies were included, including 783 interventional studies and 108 observational studies; the areas with a large number of registrations were mainly Shanghai, Beijing, Guangdong Province, etc. ; the research funds mainly came from local finance; a total of 46 tumor diseases were involved in the study, with the largest number of lung cancer (209 items), followed by tumor-related syndromes (155 items), colorectal cancer (148 items), and breast cancer (136 items); the type of research design was mainly random parallel control; the main intervention measures were TCM decoction or herbal decoction pieces (373 items), and the dosage form was mostly decoction (216 items), followed by granules (94 items); single-blind or double-blind design was used in 217 registered trials; 663 registration trials involved the collection of human samples.Conclusions:The number of clinical research registrations on the TCM prevention and treatment for malignant tumors is increasing day by day. The shortcomings such as insufficient standardization of research design and lack of research transparency still exists. In the future, TCM researchers need to strengthen cooperation with international traditional medicine clinical trial registry, giving full play to the leading role of standardization of TCM trials, and using registration as a starting point to improve the quality of clinical research.

Objective To evaluate five types of DIC scoring systems based on sepsis patients,to explore the values of different DIC scoring systems in the occurrence and prognosis of DIC in sepsis patients,and to compare the applicability of different DIC scoring systems for sepsis complicated with DIC.Methods Laboratory indexes and clinical data from sepsis patients who had been hospitalized in Gansu Provincial People's Hospital from December 1,2019 to December 31,2021 were retrospectively analyzed within 24 hours.Five types of DIC scoring systems were used to score,and the difference of diagnostic rate and discharge outcome in sepsis patients with different severity was compared.The ROC curves of five DIC scoring systems were established to evaluate the accu-racy of DIC in sepsis patients.Results The fatality rate of sepsis increased with the severity of sepsis(P<0.05).There were statistically significant differences in discharge outcomes between DIC and non-DIC in the five scoring systems(P<0.05).JMHW,CDSS and part of ISTH were detected in JAAM cases,while ISTH was detected in non-dominant ISTH cases.ISTH,JAAM,JMHW,CDSS,and non-dominant ISTH5 scoring systems were used to diagnose DIC,and absence of full health restoration and death were 3.0,3.8,4.2,3.9,and 3.0 times higher than non-DIC cases,respectively.Conclusion JAAM scoring system has higher diagnostic rate and sensitivity for adult sepsis.CDSS and JMHW scoring systems are more accurate in predicting the prognosis of sepsis patients.

Objective The combined detection of serum angiopoietin-like protein 8(ANGPTL8)and Vascular cell adhesion molecule-1(VCAM-1)levels was analyzed for the predictive value of cerebral vasospasm(CVS)after intracranial aneurysm embolization.Methods A total of 196 patients who underwent intracranial aneurysm embolization in our hospital from March 2019-March 2022 were selected as the study subjects,99 patients with CVS were in the CVS group,and 97 patients without CVS were in the non CVS group.Serum ANGPTL8 and VCAM-1 levels were detected by ELISA;the correlation between serum ANGPTL8 and VCAM-1 levels was analyzed by Pearson method,Logistic regression was used to analyze the influencing factors of CVS in patients undergoing intracranial aneurysm embolization;ROC curve was used to analyze the serum levels of ANGPTL8 and VCAM-1 to predict the cutoff value of CVS in patients undergoing intracranial aneurysm embolization;four grid table method was used to analyze the predictive value of ANGPTL8,VCAM-1 and their combination on the occurrence of CVS in patients undergoing intracranial aneurysm embolization.Results The differences between CVS and non-CVS groups were statistically significant in hypertension,Hunt-Hess grade,and Glasgow coma(GCS)scores(P＜0.05).The serum ANGPTL8 and VCAM-1 levels in the CVS group were significantly higher than those in the non-CVS group(P＜0.05).There was a positive correlation between serum ANGPTL8 and VCAM-1(r=0.468,P＜0.05).Multivariate analysis showed that high level of ANGPTL8(OR=3.652,95％CI:1.434-9.302),high level of VCAM-1(OR=2.619,95％CI:1.212-5.658),Hunt Hess grade Ⅲ-Ⅳ(OR=1.927,95％CI:1.104-3.362),GCS score of 3-8(OR=2.813,95％CI:1.257-6.295)were independent risk factors for CVS in patients undergoing intracranial aneurysm embolization.The AUC of serum ANGPTL8 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.844,and the cut-off value was 189.233 U/L;the AUC of serum VCAM-1 level in predicting CVS in patients undergoing intracranial aneurysm embolization was 0.795,and the cutoff value was 17.984 mg/L.The accuracy,sensitivity and specificity of the combined prediction for CVS were 89.81％,93.94％and 85.57％,respectively,which were obviously higher than those of the single prediction.Conclusion The serum levels of ANGPTL8 and VCAM-1 in CVS group are obviously higher than those in non CVS group.The combination of the two has a high predictive value for CVS after intracranial aneurysm embolization.

Objective:To explore the effect of nursing intervention based on nursing outcomes classification in patients with acute myocardial infarction after percutaneous coronary intervention (PCI) .Methods:From September to November 2021, a total of 86 patients with acute myocardial infarction after PCI admitted to Henan Provincial People's Hospital were selected as research subjects using convenience sampling method, and were divided into the observation group and the control group using the random number table method, with 43 patients in each group. The control group received routine nursing intervention, while the observation group received nursing intervention based on nursing outcomes classification. The incidence of complications, the scores of self-management ability, anxiety, depression, and quality of life were compared between the two groups.Results:After intervention, the incidence of complications of the observation group was lower than that of the control group, and the difference was statistically significant ( P<0.05).

Metabolic dysfunction-associated fatty liver disease (MAFLD) is the most common chronic liver disease worldwide, and the risk of all-cause and liver-related mortality significantly increases with the degree of fibrosis. Early diagnosis of MAFLD and its degree of liver fibrosis are of great significance, so it is particularly important to find an accurate and simple, non-invasive diagnostic method. In recent years, high-throughput omics technology has developed rapidly and played an important role in the non-invasive diagnosis and prediction of fibrosis degree in MAFLD. This article summarizes the application progress of genomics, epigenomics, transcriptomics, proteomics, metabolomics, microbiomics, radiomics, and the combination of multi-omics for the diagnosis of MAFLD disease.

Objective:Enriching and isolating breast cancer stem cells from breast cancer transplantation tumors in nude mice.Methods:Human breast cancer MDA-MB-231 cells were injected into the right axilla subcutaneous of 20 nude mice, and the tumor growth was observed .After 30 days, tumors were isolated and stained with hematoxylin and eosin, and then tumor cells from tissues were isolated. DMEM medium containing serum was used to cultivate isolated transplantation tumor cells, cell morphology and growth were also observed. Flow cytometry was used to detect the proportion of stem cells (CD44 +/CD24 -/low cells) in transplantation tumor cells. Serum-free DMEM medium containing epidermal growth factor (EGF), basic fibroblast growth factor (bFGF) and B27 cell supplement were used to cultivate transplantation tumor cells and to obtain cell microspheres. The proportion of stem cells on the 10th day in cell microspheres was detected by using flow cell sorter and stem cells were isolated according to the markers of cell surface. Results:After subcutaneously injecting MDA-MB-231 cells into 20 nude mice for 9 days, 17 nude mice had subcutaneous tumors with more parenchymal cells, little interstitial cells, arranged cords tumor cells, large volume of the cell and abundant cytoplasm, the nuclei in different sizes and hyperchromatic state, mitotic more common, the nucleoli clear and obvious pleomorphy. After cultivating transplantation tumor cells with DMEM medium containing serum, the cells began to grow adherent after 24 h, and the adherent proportion rose to 60% after 3 days; after 7 days, the cell proliferation was accelerated; and the cell morphology was more consistent, most of which were spindle shaped and were not significantly different from MDA-MB-231 cells; the proportion of stem cells in transplantation tumor cells was (0.10±0.02)%. After cultivating transplantation tumor cells with serum-free DMEM medium containing cell cultured supplement, the cells grow in spherical patterns, the proportion of stem cells in cell microspheres got up to (70.47±2.03)% on the 10th day.Conclusions:Subcutaneously injecting MDA-MB-231 cells in nude mice can build breast cancer nude mice ectopic transplantation tumor model. Breast cancer stem cells in the transplantation tumors can be enriched from isolated transplantation tumor cells through serum-free medium, and more stem cells can be isolated to provide the research basis for the biological characteristics of breast cancer stem cells.
