Objective: To explore the correlation between Diabetes Complication Severity Index(DCSI), C-reactive protein/albumin ratio(CAR) and death in patients with diabetic foot ulcer(DFU) and to clarify their predictive value for all-cause death in DFU patients. Methods: Retrospectively analyzed the clinical data of 354 DFU patients who were treated in the Endocrinology Department of the First Affiliated Hospital of Anhui Medical University from July 2019 to December 2022. Based on survival status during follow-up, patients were divided into a survival group(n=268) and a death group(n=86). Univariate and multivariate Cox regression analyses were used to identify risk factors for all-cause death in DFU patients. Receiver operating characteristic(ROC) curves were plotted to evaluate the predictive value of DCSI, CAR, and their combination for all-cause death in DFU patients. Kaplan-Meier curves were used to explore the impact of different DCSI and CAR levels on survival in DFU patients. Results: Univariate Cox regression analysis showed that older age, history of hypertension, higher Wagner classification levels, and elevated levels of CRP, Scr, FDP, DCSI score, and CAR were associated with a higher risk of death in DFU patients(P<0.05). Higher levels of HGB, HCT, ALB, or eGFR were associated with a lower risk of death. Patients receiving combined insulin and oral hypoglycemic medication had a lower risk of death compared to those receiving only insulin therapy(P<0.05). Multivariate Cox regression analysis indicated that older age, higher levels of Scr, DCSI, and CAR were independent risk factors for all-cause death in DFU patients, while higher levels of ALB and combined insulin and oral hypoglycemic therapy were protective factors. ROC curve analysis showed that the AUC values for DCSI, CAR, and their combination were 0.652, 0.633, and 0.686, respectively. Kaplan-Meier curve analysis revealed that patients with high DCSI scores(≥4.5) had a lower survival rate compared to those with lower DCSI scores(<4.5). Similarly, patients with high CAR levels(≥0.124) had a lower survival rate compared to those with lower CAR levels(<0.124). Conclusion High levels of DCSI and CAR are independent risk factors for all-cause death in DFU patients. DCSI, CAR, and their combination have predictive value for all-cause mortality in DFU patients.

Objective To establish a fast,stable,and sensitive zebrafish model of osteoporosis(OP)using different method.Methods OP models were induced by iron overload or prednisolone(Pred),and bone formation and mortality were observed.The groups were divided into:Control group,model group(include FAC group and Pred group),and positive control group(AC group).Ammonium ferric citrate was used as the model drug in the iron-overload induction method.For the Pred induction models,the modeling time for the Pred-3 days post-fertilization(dpf)method was 3～9 dpf,the modeling time for the Pred-5 dpf method was 5～10 dpf,and Pred was administered from 3 dpf and removed from 7～9 dpf for the Pred withdrawal method.To compare the anti-osteoporosis(OP)effects of commonly used drugs such as Alfacalcidol(AC),Calcitriol(CA),and Alendronate(AL),it's important to select a stable and sensitive positive control drug and to further optimize different staining methods and conditions.Results There was no significant effect of ammonium ferric citrate 500 μg/mL on bone formation.Bone formation and the length of the first vertebra were significantly decreased in the Pred group induced by Pred-3 dpf compared with those in the control group(P＜0.01,P＜0.05),but zebrafish mortality was higher.There was no significant difference between the Pred-5 dpf method,but bone formation was significantly reduced in the Pred withdrawal group(P＜0.01),with no mortality.Alfacalcidol,calcitriol,and alendronate all had anti-OP effects,with CA having the most sensitive and stable anti-OP effect.Alizarin red staining showed that the optimal dye parameters were 0.02%concentration for dyeing 2 h,with washing in 0.5%KOH and glycerol under the conditions of a 3∶1 ratio for 3 h followed by a 1∶1 ratio for 14 h.The result of staining showed that calcein was more sensitive for staining bone nodes and ARS staining was more sensitive for staining the first vertebra.Conclusions The Pred withdrawal method can be used to establish a rapid,stable,and sensitive OP model in zebrafish as a reliable model for studying OP.

Objective To analyze the literature of leech in medicine using CiteSpace knowledge map,comprehensively understand the research status,hotspots and development trends of component analysis and pharmacological effects of leech,and provide reference for researchers in the field of leech.Methods CiteSpace 6.1 R3 software was used to analyze the relevant literature of leech in the field of medical research in CNKI and Web of Science databases from 1996 to 2022.The bibliometric and visual analysis of the number of articles,authors,research institutions,keyword co-occurrence,clustering and emergence were carried out.Results A total of 1 115 Chinese articles in CNKI database and 237 English articles in Web of Science database were included.The analysis of Chinese and English literature showed that the author Shi Hongzhuan had the largest number of Chinese articles,and the German author Hildebrandt had the largest number of English articles.Shandong University of Traditional Chinese Medicine and Chinese Academy of Sciences were the institutions with the largest number of articles in Chinese and English respectively.The country with the most published English literature is the United States.Chinese and English keyword co-occurrence and cluster analysis showed that Chinese literature focused on the study of its active ingredient hirudin,including molecular structure,pharmacological efficacy,mechanism of treating thrombosis,coronary heart disease,kidney disease and other diseases,and paid attention to the differences in the active ingredients of different types of leeches.In addition,English literature focused on the clinical external use of living leeches.The emergence of keywords suggested that the mechanism of action,the search and synthesis of hirudin analogues,and the pharmacodynamic mechanism of compatibility application were not only the current research hotspots,but also the future hot spots.Conclusion The analysis of leech components,the pharmacological mechanism of leech in the treatment of cardiovascular diseases,chronic kidney diseases and other diseases have always been the research hotspots.Hirudin analogues,the pharmacodynamic mechanism of compatibility application,network pharmacology,molecular docking and so on may be the future research hotspots and trends of leeches.

Objective To quickly observe the tonic effects of Cervi Colla on enriching blood,strengthening bones and anti-aging in zebrafish model.Methods Glyphosate(Gly)was used to construct the erythrocyte injury model in adult zebrafish,and methotrexate(MTX)was used to construct the hematopoietic function injury model of juvenile zebrafish.Prednisolone(Pred)was used to establish the inhibition model of bone formation in zebrafish larvae.The ocular cell apoptosis model of zebrafish larvae was established by dibutyl phthalate(DBP).Results Cervi Colla could improve the Gly-induced abnormal erythrocyte nucleus in adult zebrafish and promote the expression of hematopoietic factors SCL and GATA1.Cervi Colla improved Pred-induced inhibition of bone formation in juvenile zebrafish,and promoted the expression of osteoblast-related gene ALP and Runx2a.The number of ocular cell apoptosis induced by DBP was decreased,and the expression of anti-apoptotic factor Bcl-2 was promoted.Conclusion Cervi Colla has significant effects on protecting erythrocyte,protecting hematopoiesis,protecting bone formation and anti-apoptosis.These effects may be related to replenish blood,anti-osteoporosis,and anti-aging.This study provides a scientific basis for the clinical application of Cervi Colla,and lays a foundation for further development and application.

Lung cancer is the leading cause of cancer-related deaths， and standard treatments for lung cancer， including surgery， radiotherapy， chemotherapy， targeted therapy， and immunotherapy， have shown significant clinical effects. However， current available treatment strategies are still unable to cure the disease. Since the majority of lung cancer patients are diagnosed at an advanced stage， surgical options are often lost， and the primary approach is typically a combination of radiotherapy and chemotherapy. However， the adverse reactions associated with these treatments limit their effectiveness and application， and the damage caused to normal tissues is often more severe than that inflicted on the tumor. Currently， traditional Chinese medicine （TCM） has been used as part of combination therapy for cancer treatment due to its unique system of syndrome differentiation， flexible compatibility， and safety and efficacy. TCM prescriptions and single drugs with multiple components and targets can simultaneously regulate multiple pathways. As reported， among numerous pathways involved in the regulation of lung cancer， the nuclear factor-κB （NF-κB） signaling pathway plays a key role in inducing cell transcription and is one of the main pathways involved in the occurrence and development of lung cancer. It can specifically regulate inflammatory responses， cell proliferation， apoptosis， invasion and metastasis， angiogenesis， and multidrug resistance in lung cancer. TCM prescriptions and single drugs can inhibit lung cancer cell proliferation， invasion， and metastasis， induce apoptosis and autophagy in lung cancer cells， suppress angiogenesis， regulate immune function， and treat multidrug resistance by regulating the NF-κB signaling pathway. Therefore， they play a role in intervening in lung cancer. However， there is currently a lack of systematic literature research that comprehensively summarizes and elucidates these aspects in China and abroad. Therefore， it is important to provide a systematic elucidation of the mechanism underlying the regulation of the NF-κB signaling pathway in lung cancer and review TCM interventions in lung cancer based on the NF-κB signaling pathway. This study is expected to provide references for the clinical application of lung cancer therapeutic drugs and the development of new drugs.

Objective To study the effect of corrected TIMI frame count (CTFC) of infarction related artery on systolic function of infarct area of myocardium after primary percutaneous coronary intervention (PCI) in patients with acute myocardial infarction (AMI). Methods One hundred and six patients with AMI having undergone successful PCI in Cangzhou Central Hospital were selected, and they were divided into two groups (each, 53 cases). The standard of fast or slow flow was in accord to the CTFC of infarction related artery (IRA) measured soon after successful PCI. The patients with greater value of CTFC were enrolled in the slow flow group, while the patients with smaller such value were assigned in the fast flow group. At 6, 12, 24 and 48 hours after PCI, the venous plasma MB isoenzyme of creatine kinase (CK-MB) level was measured. And at 1 week, 1 month and 3 months after PCI, the left ventricular ejection fraction (LVEF) was measured by cardiac ultrasound, and the levels of radial strain (RS) and longitudinal strain (LS) of the infarct area were measured via speckle tracking imaging (STI). The differences in CTFC, CK-MB, RS and LS between the two groups were analyzed, and the correlations between the strains and CTFC, CK-MB were analyzed by Pearson linear correlation method. Results After successful PCI, the CK-MB of fast flow group was higher than that of the slow flow group at 6 hours. However, the CK-MB of slow flow group was higher than that of the fast flow group after 12 hours, appearing separate phenomenon, and the statistical significance occurred beginning from 24 hours after PCI (U/L, 24 hours:98.43±11.65 vs. 86.43±18.97, 48 hours:51.09±8.94 vs. 49.80±6.92, both P<0.05). CTFC in fast flow group was significantly lower than that of slow flow group (frame: 22.69±4.83 vs. 26.14±5.67, P < 0.01). After 3 months of follow-up, LVEF in fast flow group was higher than that of the slow flow group, but the difference had no significance (P > 0.05). RS and LS in fast flow group were higher than those in slow flow group, and the statistically significant difference appeared from 1 month after PCI (1 month RS:29.74±6.66 vs. 26.86±5.61, LS:-16.37±3.91 vs. -15.27±3.22, 3 months RS: 30.03±6.31 vs. 27.63±5.67, LS: -17.74±3.96 vs. -15.75±4.17, all P < 0.05). Pearson linear correlation showed:the strains (both RS and LS) and CK-MB had no significant relation (both P>0.05). Both RS and LS at 1 week, 1 month and 3 months were of significantly positive correlation with CTFC of each group (fast flow group:r value of CTFC and RS was respectively-0.526,-0.515,-0.532, r value of CTFC and LS was respectively-0.532,-0.541,-0.572;slow flow group:r value of CTFC and RS was respectively-0.691,-0.685,-0.702, r value of CTFC and LS was respectively-0.621,-0.584,-0.605, all P<0.01). Conclusion CTFC has some relationship with the recovery of the systolic function in area of infarct myocardium after PCI, and can be regarded as an important index to predict the long-term prognosis in patients with AMI.

OBJECTIVETo investigate whether transplantation of autologous peripheral blood CD34+ stem cells is a viable approach for treating patients with advanced cirrhosis,which is currently hindered by a shortage in liver donors.

METHODSA total of 100 patients with advanced cirrhosis and who had failed to respond to conservative therapy were recruited for transplantation of autologous peripheral blood CD34+ stem cells.The success of transplantation was investigated 6-and 12-months later by measuring markers of liver biosynthesis function (coagulation,albumin level,indocyanine green clearance,Child-Pugh score) and assessing pathological changes (Knodell score) and morphologic changes in the liver tissue.Complications were also recorded during follow-up.

RESULTSThe 1-year cumulative survival rate was 100%. Fifty-two patients with massive ascites showed gradual reduction and disappearance of the ascites.Four patients experienced upper gastrointestinal bleeding and three patients developed with hepatic encephalopathy (I-II degree) at 3 months post-transplantation.All patients showed significantly improved liver biosynthesis function,liver elasticity and Knodell score after transplantation (P less than 0.05).

CONCLUSIONAutologous peripheral blood CD34+ stem cell transplantation is a safe and effective treatment for advanced cirrhosis,and has high cost-benefit since it improves liver function,liver histology,and quality of life.
