Effect of oral fish oil on wound healing in patients with diabetic foot ulcers:a randomized,double-blind,placebo-controlled study / 重庆医学

Objective To investigate the effect of oral fish oil on wound healing and related indexes in patients with diabetic foot ulcer(DFU).Methods A randomized,double-blind,placebo-controlled design was used to recruit 68 patients with DFU aged 18-80 years old in the hospital,and the baseline clinical data of the patients were collected.The patients were randomly divided into experimental group(32 cases,fish oil soft capsule,3 g/d)and control group(33 cases,corn oil soft capsule,3 g/d)by random number generated by Ex-cel,and the intervention lasted for 12 weeks.The primary endpoints included the proportion of complete wound healing and healing area≥50%.The secondary endpoints included wound area,healing time,inflamma-tion index,glucose metabolism index,nutrition related index and wound reinfection.Additionally,the influen-cing factors of wound healing were analyzed.Results After intervention,the proportion of complete wound healing and healing area≥50%in the experimental group was significantly higher than that in the control group(P=0.007,0.039).In the subjects with complete wound healing,the mean healing time in the experi-mental group was shorter than that in the control group,but the difference was not statistically significant(P=0.132).The reduction area of wound area in the experimental group was significantly larger than that in the control group(P=0.045).The decrease of interleukin(IL)-6 and IL-8 in the experimental group was significantly higher than that in the control group(P<0.05).There was no significant difference in the reduc-tion of C-reactive protein(CRP),tumor necrosis factor-α(TNF-α),neutrophil-to-lymphocyte ratio(NLR),glycated hemoglobin A1c(HbA1c)and platelet-to-lymphocyte ratio(PLR)between the two groups(P>0.05).The improvement of prealbumin(PA)in the experimental group was higher than that in the control group,but the difference was not statistically significant(P>0.05).Multivariate logistic regression analysis showed that oral fish oil intervention(OR=6.771,95%CI:1.787-25.652),HbA1c(OR=4.149,95%CI:1.026-16.770)and ulcer type(OR=4.319,95%CI:1.026-18.173)were the influencing factors of wound healing(P<0.05).Conclusion Oral fish oil promotes wound healing in patients with DFU,which may be re-lated to improving the level of chronic inflammation in the body.

Correlation Analysis between the Common Clinical Indexes and Diabetic Foot Ulcer / 昆明医科大学学报

Objective To analyze the relationship between the common clinical indicators and diabetic foot ulcer(DFU)in type 2 diabetes mellitus(T2DM)patients by using the cross-sectional study and to provide the reference indicators for clinical DFU monitoring and prognosis evaluation.Methods A total of 115 T2DM patients admitted to the Department of Endocrinology,the Second Affiliated Hospital of Kunming Medical University from June 2021 to June 2023 were selected as the study objects and were divided into group A(with DFU)and group B(without DFU)according to whether they had DFU.Those in group A were then divided into group A1(Wagner0-1),group A2(Wagner2-3)and group A3(Wagner4)according to Wagner classification.The differences of general data,blood pressure,blood glucose,blood lipids and other common clinical indicators among all of the groups were compared,and the correlation between DFU and the above indicators was explored.Results Diabetes duration,D-dimer(DD),systolic blood pressure and other indexes in group A were higher than those in group B and there was a statistically significant difference(P<0.05).DD was the main risk factor for DFU in T2DM patients.Diabetic course in patients with DFU was positively correlated with the age(r>0,P<0.05),and negatively correlated with fasting blood glucose(FPG)level and 2hPG level at 2 hours after meals(r<0,P<0.05).The levels of interleukin-6(IL-6)and C-reactive protein(CRP)in A1 and A2 groups were lower than those in A3 group,the levels of neutrophils and leukocytes in A1 group were lower than those in A3 group,and the high density lipoprotein cholesterol(HDL-C)in A1 group was higher than that in A2 group and there was a statistically significant difference(P<0.05).Conclusion DD and systolic blood pressure are the main risk factors for DFU,and DD is closely related to DFU.The older the patients with T2DM,the later the onset of DFU.The worse the blood glucose control,the earlier the onset of DFU.HDL-C is a protective factor for peripheral vascular disease in T2DM patients.

Huangqi Yanghe Decoction regulates PI3K/AKT/NF-κB signaling pathway to promote wound healing in diabetes foot ulcer rats / 天津医药

Objective To explore the effect of Huangqi Yanghe Decoction on wound healing of diabetic foot ulcer(DFU)rats based on phosphatidylinositol 3-kinase(PI3K)/protein kinase B(AKT)/nuclear factor-κB(NF-κB)signal pathway.Methods DFU rat model was constructed,and 48 rats successfully modeled were randomly divided into the model group,the Huangqi Yanghe Decoction low(8.5 g/kg)group,the Huangqi Yanghe Decoction high(17 g/kg)dose group and the Huangqi Yanghe Decoction high dose(17 g/kg)+LY294002(PI3K/AKT pathway inhibitor,0.3 mg/kg)group.There were 12 rats in each group.Another 12 rats were selected as the control group.Rats in each group were given corresponding drug intervention for 4 weeks.After the 14th and 28th day-administration,the general state and wound changes of rats were observed,and the wound healing rate was calculated.The fasting blood glucose(FBG)level of rats was measured,and the percutaneous partial pressure of oxygen(TcpO2)of tissue around the wound was detected.Serum levels of vascular endothelial growth factor(VEGF),hypoxia inducible factor-1α(HIF-1α),C-reactive protein(CRP)and interleukin(IL)-6 were determined by enzyme linked immunosorbent assay.Histopathological changes of the wound were observed by hematoxylin-eosin staining.Immunohistochemical staining was used to measure the microvascular density of rat wound tissue.The protein expression levels of PI3K,phosphorylated PI3K(p-PI3K),AKT,phosphorylated AKT(p-AKT),NF-κB p65,phosphorylated NF-κB p65(p-NF-κB p65)and NF-κB inhibitory protein α(IκB-α)in rat wound tissue were determined by Western blot assay.Results Rats in the control group had smooth hair color,normal diet,drinking water and excretion,more active,wound healing fast,less inflammatory reaction in wound tissue,and there were more new blood vessels.Fibroblasts and collagen matrix were abundant in granulation tissue.In the model group,the fur color of rats was dull and matte,and the activity was reduced.The symptoms of polydipsia,polyphagia and polyuria were appeared in the model group,the wound color was dark,and edema and ulcer appeared in the surrounding tissue,a large number of inflammatory cells infiltrated in the wound tissue,accompanied by tissue necrosis and exudation,fewer neovascularization and fibroblasts were observed.Wound healing rate,TcpO2 in wound surrounding tissue,serum VEGF,HIF-1α,microvascular density,p-PI3K,p-AKT and IκB-α protein expression levels in wound tissue were decreased,and FBG,serum CRP,IL-6,p-NF-κB p65 protein expression in wound tissue were increased(P＜0.05).Compared with the model group,the state of rats was gradually improved in the Huangqi Yanghe Decoction low and high dose groups,and the lesion degree of wound tissue was reduced successively,wound healing rate,TcpO2 in wound surrounding tissue,serum VEGF,HIF-1α,microvascular density,p-PI3K,p-AKT and IκB-α protein expression levels in wound tissue were increased in turn(P＜0.05).The FBG,serum CRP,IL-6 and p-NF-κB p65 protein expression in wound tissue were decreased in turn(P＜0.05).LY294002 could partially reverse the therapeutic effect of high-dose Huangqi Yanghe Decoction on DFU rats(P＜0.05).Conclusion Huangqi Yanghe Decoction can regulate PI3K/AKT/NF-κB pathway,inhibit inflammatory response in DFU rats,promote angiogenesis and thus promote wound healing.

NLRP3 inflammasome and inflammatory factor levels predict early infection after flap repair of diabetic foot ulcers / 中国组织工程研究

BACKGROUND:Studies have shown that nucleotide binding oligomerization domain-like receptor protein 3(NLRP3)inflammasome,interleukin-18,and interleukin-1β levels can induce an inflammatory cascade response to release inflammatory factors,affect metabolic stress,and damage endothelial cells involved in the development and progression of diabetic foot ulcers,which can provide a reference for early infections. OBJECTIVE:To investigate the predictive effect of peripheral blood mononuclear cell NLRP3 inflammasome,interleukin-18 and interleukin-1β levels on early infection after flap repair of diabetic foot ulcers. METHODS:A total of 147 patients with diabetic foot ulcers were selected and divided into infection group and non-infection group according to whether they were infected within 1 week after operation.Logistic regression was used to analyze the relationship between NLRP3 inflammasome,interleukin-18 and interleukin-1β levels in peripheral blood mononuclear cells and early postoperative infections,and to evaluate their predictive values. RESULTS AND CONCLUSION:In 147 patients with diabetic foot ulcers,35 cases(23.81%)were infected within 1 week after operation,and 47 strains of pathogenic bacteria were isolated,including 25 strains of Gram-positive bacteria(53.19%)and 22 strains of Gram-negative bacteria(46.81%).Univariate analysis showed that Wagner grade,presence of comorbid diabetic nephropathy,operation time,peripheral blood NLRP3 mRNA,Caspase-1 mRNA,ASC mRNA,interleukin-18 and interleukin-1β levels were risk factors for early postoperative infections(all P＜0.05).Multivariate analysis suggested that Wagner grade,NLRP3 mRNA,Caspase-1 mRNA,ASC mRNA,high interleukin-18,interleukin-1β were independent risk factors(all P＜0.05).Receiver operator characteristic curve results showed that the area under the receiver operator characteristic curve of NLRP3 mRNA,Caspase-1 mRNA,ASC mRNA,interleukin-18 and interleukin-1β for early postoperative infections in patients with diabetic foot ulcers was 0.823,0.705,0.676,0.811 and 0.853,respectively,and the area under the curve of combined predictive efficacy was 0.915.To conclude,patients with diabetic foot ulcers are mainly affected by Gram-positive bacteria,and the levels of NLRP3 inflammasome,interleukin-18 and interleukin-1β in peripheral blood mononuclear cells are independent risk factors for early postoperative infections.The combined prediction efficacy of these indicators is better and deserves further in-depth study.

Antibiotic-loaded bone cement enhances ability of tibial cortex transverse transport for treating infected wounds / 中国组织工程研究

BACKGROUND:Diabetic foot patients with wound infections constitute a large patient population,and there is currently no satisfactory treatment approach. OBJECTIVE:To investigate the clinical efficacy of a modified tibial cortex transverse transport combined with antibiotic-loaded bone cement for treating refractory diabetic foot ulcers. METHODS:A total of 46 diabetic foot ulcers patients,27 males and 19 females,with an average age of 64.37 years,were selected from Beijing Chaoyang Hospital,Capital Medical University and Beijing Chaoyang Integrative Medicine Rescue and First Aid Hospital from January 2020 to January 2023.All of them underwent the modified tibial cortex transverse transport combined with antibiotic-loaded bone cement treatment.Ankle-brachial index,WIFi(Wound/Ischemia/Foot infection)classification,pain visual analog scale score,and ulcer area were recorded before and 3 months after surgery. RESULTS AND CONCLUSION:(1)The mean ulcer healing time for the 46 patients was(58.07±24.82)days.At 3 months postoperatively,there were significant improvements in ankle-brachial index,pain visual analog scale score,ulcer area,and WIFi classification in 46 patients,as compared to the preoperative values,with statistically significant differences(P<0.05).Two patients experienced pin-tract infections,without infection or ulcer recurrence during the follow-up period.(2)These findings indicate that the modified tibial cortex transverse transport combined with antibiotic-loaded bone cement effectively alleviates patients'pain,improves lower limb circulation,controls infections,and promotes ulcer healing.

Illness narratives and cultural implications for diabetic foot patients from the perspective of anthropology / 中国医学伦理学

Diabetic foot is one of the common chronic complications， the most common cause of hospitalization， and even the main cause of disability and death among diabetic patients. In the process of disease occurrence， development， and treatment， patients experience complex changes in physical， psychological， and social relationships. Their understanding and practice of the disease is a constant process of construction and change， which contains strategic practices influenced by factors such as disease progression， family relationships， culture and traditions of social， and doctor-patient interactions. Based on the research concepts in the field of medical anthropology， this paper applied field research methods such as survey interviews and participatory observation， and took the rich and varied and personalized narrative of diabetic foot patients as the entry point to understand their unique and detailed disease stories， as well as focused on answering the changes in the views of illness， treatment， family， society， and the body outlook experienced by diabetic foot patients. This paper aimed to provide a new perspective for understanding this group， as well as offer valuable insights for improving their treatment and management， which will help promote the overall health and quality of life with diabetic foot patients.

Based on Daoyin therapy of Baduanjin and the Origin and Indicators of Disease （《诸病源候论》）， a Daoyin prescription for diabetic foot was compiled and created. Based on the zang-fu concept of "One Qi Circulation"， combined with the theory of chief， deputy， assistant and envoy， this article explained the theoretical basis and functional mechanism of the Daoyin prescription for diabetic foot. This Daoyin therapy is mainly based on the prone position movements， which includes seven movements， namely， pull-up， knee bending， toe tilting， phoenix nodding， internal rotation of taiji， two hands climbing feet and closing. With "phoenix nodding" and "tilting toes" as the chief， with the help of toes opening-closing and pointing-pressing momentum in prone position， regulating the central qi； with "bending the knee" and "internal rotation of taiji" as the deputy， knee and ankle flexion and extension can unblock the meridians of liver and lungs； with "pull-up" and "two hands climbing feet" as the assistant， on the one hand， assisting to unblock zang-fu organs， on the other hand， applying the yang of the foot taiyang bladder channel and du mai to warm the cold and dampness； with "closing" as the envoy to regulate all organs， so that the blood return to the natural flow of circulation. Diabetic foot Daoyin therapy could regulate internal organs and qi circulation of body， and provides a new idea for the treatment of diabetic foot.

Prevalence of Anemia in Patients with Diabetes Mellitus: A Systematic Review and Meta-Analysis / 生物医学与环境科学（英文）

OBJECTIVE@#Anemia is a common public health concern in patients with type 2 diabetes worldwide. This study aimed to identify the prevalence of anemia among patients with diabetes.@*METHODS@#Electronic databases, including PubMed, Scopus, Web of Sciences, and Google Scholar, were searched systematically for studies published between 2010 and 2021. After removing duplicates and inappropriate reports, the remaining manuscripts were reviewed and appraised using theNewcastle-Ottawa Scale (NOS) tool. A random-effects model was used to calculate the pooled estimates of the extracted data using Stata version 17. Heterogeneity of the studies was assessed using the Q statistic.@*RESULTS@#A total of 51 articles containing information on 26,485 patients with diabetes were included in this study. The articles were mainly from Asia (58.82%) and Africa (35.29%). The overall prevalence of anemia was 35.45% (95% CI: 30.30-40.76), with no evidence of heterogeneity by sex. Among the two continents with the highest number of studies, the prevalence of anemia in patients with diabetes was significantly higher in Asia [40.02; 95% CI: 32.72-47.54] compared to Africa [28.46; 95% CI: 21.90-35.50] ( P for heterogeneity = 0.029). Moreover, there has been an increasing trend in the prevalence of anemia in patients with diabetes over time, from [15.28; 95% CI: 9.83-22.21] in 2012 to [40.70; 95% CI: 10.21-75.93] in 2022.@*CONCLUSION@#Globally, approximately 4 in 10 patients with diabetes suffer from anemia. Therefore, routine anemia screening and control programs every 3 months might be useful in improving the quality of life of these patients.

Changes of Th1 and B cells and related genes in diabetic foot ulcer healing / 中国糖尿病杂志

Objective To explore the changes in Th1 cell,B cell and related gene expression during the healing of diabetic foot ulcers(DFU).Methods Lesional skin tissues from DFU patients surgically treated in our hospital from January 2022 to January 2023 were selected.DFU associated gene expression data were collected from GSE80178 and GSE143735 datasets.The expressions of genes(DEGs)between ulcer and no-ulcer patients were identified.Bioinformatics methods were used to identify abnormal immune cells and key genes.Finally,the key results were detected by RT-qPCR and flow cytometry.Results A total of 548 common DEGs were identified in two datasets.In 14 co-expression modules,darkgrey and darkgreen were most related to ulcer,which were mainly associated with the regulation of enzyme activity,immune function and endocrine regulation.Flow cytometry showed that Th1 and B cells were highly infiltrated in ulcer tissue and decreased in healing tissue.MMP13,S100A9 and STAT4 were involved in immune signaling pathways.MMP13 and STAT4 were lowly expressed in healed ulcers,whereas S100A9 was highly expressed.Conclusion Reduced levels of Th1 and B cell infiltration may promote DFU healing.

Expression of Hsa_circ_0003928 in diabetic foot ulcer and its relationship with severity and prognosis / 中国糖尿病杂志

Objective To investigate the expression of serum Hsa_circ_0003928 in patients with diabetic foot ulcer(DFU)and its relationship with the severity and prognosis of disease.Methods 113 DFU patients were selected as the study subjects.According to the severity of infection,19 cases were classified into level 1(no infection),40 cases at level 2(mild infection),20 cases at level 3(moderate infection),and 34 cases at level 4(severe infection).According to the prognosis of DFU patients,they were divided into good prognosis group(GP,n=63)and poor prognosis group(PP,n=50).The baseline data and levels of IL-6,C-RP and Hsa_circ_0003928 were compared among the four groups.Logistic regression was used to analyze the risk factors of poor prognosis in patients with DFU.The receiver operating characteristic(ROC)curve was used to analyze the value ofHsa_circ_0003928,C-RP and IL-6 in predicting the poor prognosis in DFU patients.Results The DFU duration,infection grade 3～4,serum creatinine,uric acid,BUN,C-RP,IL-6 and Hsa_circ_0003928 levels in PP group were significantly higher than those in GP group(P＜0.05 or P＜0.01).Grade 3～4 DFU patients had higher Hsa_circ_0003928 expression than grade 1～2(P＜0.01).Logistic regression analysis showed that long duration of DFU,infection grade 3～4,higher levels of BUN,C-RP,IL-6 and Hsa_circ_0003928 were risk factors for poor prognosis in DFU patients.ROC curve showed that Hsa_circ_0003928 had the greatest AUC(0.882,95％CI 0.819～0.942)in predicting poor prognosis in DFU patients,with sensitivity 87.5％and specificity 85.6％,respectively.Conclusion Elevated Hsa_circ_0003928 is associated with DFU severity and poor prognosis,which has certain predictive value for the prognosis of DFU patients.

Correlation between inflammatory factors and serum ICAM-1 expression in patients with diabetic foot ulcer / 中国糖尿病杂志

Objective To investigate the expression of intercellular adhesion molecule 1(ICAM-1)in patients with diabetic foot ulcer(DFU)and its correlation with inflammatory cytokines.Methods A total of 152 patients with DFU(DFU group)and 133 patients with type 2 diabetes mellitus(T2DM group)admitted to our hospital from January 2021 to December 2022 were selected as the study group.120 healthy people matched in age and sex were set as the control group(NC group).Pearson correlation analysis was applied to analyze the correlation between serum ICAM-1 and wagner grade in DFU patients.Results HbA1c,TG,ICAM-1,C-RP,TNF-α,IL-6,IL-18,IL-1β in NC,T2DM and DFU groups gradually increased,but HDL-C gradually decreased(P＜0.05).Pearson correlation analysis showed that serum ICAM-1 was positively associated with C-RP and TNF-α,IL-6,IL-18,IL-1β and wagner grading in DFU patients(P＜0.01).Logistic regression analysis showed that ICAM-1,C-RP,HbA1c and IL-18 were the influencing factors of DFU.Conclusion High levels of serum ICAM-1 in DFU patients are closely related to inflammatory factors and Wagner grading,which helps to identify the severity of the condition.
