Meta analysis of clinical efficacy of combination of traditional Chinese and western medicine in the treatment of venous ulcer of lower extremities

Objective: To test the therapeutic effect of integrated traditional Chinese and western medicine on venous ulcer of lower limbs by Meta analysis method, and then to propose the best clinical treatment scheme. Methods: Domestic databases in the past 20 years (January 1999-December 2019) were searched by computer, including China Journal Full-text Database (CNKI), VIP, Wanfang and CBM. Literature was screened according to inclusion and exclusion criteria. Cochrane risk assessment tool was used to evaluate the quality of the included literature. Two-classification method was used to extract data. RevMan 5.3 software was used to make statistical analysis of the data. Results: Eleven articles were finally included, totaling 1,576 patients, 804 cases in the treatment group and 772 cases in the control group. Meta-analysis results show that there is no difference in heterogeneity and bias among the included literatures. The total effective rate (risk ratio [RR]=1.12, 95% confidence interval [CI]=1.09-1.15) of integrated traditional Chinese and western medicine in treating venous ulcer of lower limbs is higher, which is obviously better than that of western medicine alone. Conclusion: Through data analysis, it is concluded that in the study population, the treatment of integrated traditional Chinese and western medicine has a significant effect on venous ulcer of lower limbs. Make up for the deficiency of simple western medicine treatment, improve the cure rate and reduce the recurrence rate. However, there is currently a lack of relevant high-quality literature, so a large sample size, rigorous and standardized experimental design and randomized double-blind clinical study are needed to further test the conclusions.

Lower Extremity Arterial Disease in Patients with Type 2 Diabetes: Prevalence and Associated Factors at the Libreville University Hospital Center

Introduction: Lower extremity arterial disease in diabetic patients has distinct characteristics. Objectives: To study the hospital frequency of lower extremity arterial disease and identify associated factors in diabetic patients at the Libreville University Hospital Center (CHUL). Materials and Methods: This was a cross-sectional study conducted from July 1, 2023, to January 31, 2024, in the endocrinology department of the CHUL. All patients with type 2 diabetes over the age of 18 admitted to this department, regardless of the reason for hospitalization, who provided informed consent, were included. Socio-demographic data and cardiovascular risk factors were recorded. Personal and family cardiovascular history and functional symptoms were investigated. The physical examination included measuring blood pressure, heart rate, and the ankle-brachial index in all patients. Results: A total of 219 patients were included, of whom 75 had lower extremity arterial disease, representing a prevalence of 34.24%. It was compensated in 28 cases (37.33%) and decompensated in 39 patients (52%). In eight cases (10.67%), there was critical chronic ischemia. Cardiovascular risk factors associated with diabetes were physical inactivity (89.5%), hypertension (55.25%), overweight (49.77%), obesity (22.84%), and smoking (10.04%). In multivariate analysis, only hypertension (OR = 2.09;95% CI: 1.05 - 4.17;p = 0.035) and LDL cholesterol (OR = 2.75;95% CI: 1.10 - 6.85;p = 0.03) were significantly associated with lower extremity arterial disease in diabetics at the University Hospital of Libreville. Conclusion: Lower extremity arterial disease is common in diabetic patients at the University Hospital of Libreville. It is often asymptomatic, thus requiring systematic screening.[-rId11-]

Lower extremity amputations and long-term outcomes in diabetic foot ulcers:A systematic review

BACKGROUNDDiabetes mellitus causes a large majority of non-traumatic major and minoramputations globally. Patients with diabetes are clinically complex with amultifactorial association between diabetic foot ulcers (DFU) and subsequentlower extremity amputations (LEA). Few studies show the long-term outcomeswithin the cohort of DFU-associated LEA.AIMTo highlight the long-term outcomes of LEA as a result of DFU.METHODSPubMed/MEDLINE and Google Scholar were searched for key terms, “diabetes”,“foot ulcers”, “amputations” and “outcomes”. Outcomes such as mortality, reamputation,re-ulceration and functional impact were recorded. Peer-reviewedstudies with adult patients who had DFU, subsequent amputation and follow upof at least 1 year were included. Non-English language articles or studiesinvolving children were excluded.RESULTSA total of 22 publications with a total of 2334 patients were selected against theinclusion criteria for review. The weighted mean of re-amputation was 20.14%,29.63% and 45.72% at 1, 3 and 5 years respectively. The weighted mean of mortality at 1, 3 and 5 years were 13.62%, 30.25% and 50.55% respectively withsignificantly higher rates associated with major amputation, re-amputation andischemic cardiomyopathy.CONCLUSIONPrevious LEA, level of the LEA and patient comorbidities were significant riskfactors contributing to re-ulceration, re-amputation, mortality and depreciatedfunctional status.

Application of negative pressure closed drainage in the treatment of venous ulcer of lower limbs

Venous ulcer of lower extremities is a serious manifestation of venous insufficiency of lower extremities in the later stage,which is characterized by inflammatory exudation at the initial stage,followed by skin rupture,and finally forms the whole layer of skin atrophy and necrosis,which does not heal for a long time.How to promote ulcer healing is the most important problem in the treatment of venous ulcers of lower extremities.Vacuum sealing drainage(VSD)is constantly used in clinic and plays a unique advantage in wound healing.This paper mainly reviews the present situation of venous ulcer of lower extremities and summary,principle,application progress,attentions and prospect of VSD at home and abroad.

Ozone Therapy in a Patient with Diabetic Foot Ulcerations and a Decision for Amputation

Background: Diabetic foot together with open wounds in distal type peripheral arterial disease constitutes a challenge in therapeutic planning. Ozone therapy may unveil new horizons in management. Case Report: A 67-year-old woman with diabetes mellitus was applied with open wounds at the bottom of her foot with purulent discharge, with a decision for above ankle amputation. She had had numerous interventions for her wounds including metatarsal amputations due to osteomyelitis and had been on an intense treatment including antibiotics, insulin, antihypertensives and antiaggregants. Angiogram revealed diffuse peripheral arterial disease in lower extremities. All medication but antihypertensives was stopped. She received major medical ozone application as 2000 gamma/session i.v. for 2 weeks, external ozone sac application starting from 60 and dropping to 30 gamma/session for 3 weeks and ozone insuflation 40 gamma/session for 10 sessions. Her purulent discharge ceased after the third session and the atonic debris of the wounds exfoliated, the wounds healed from the base towards the surface of the skin. She was then put on cilostazol and clopidogrel therapy. Conclusion: By being one of the known strongest bactericide, virucide, and fungicide elements, medical ozone therapy stimulates and upregulates the antioxidant system of the body with its hormesis effects. After the cessation of all circulatory system supporting medication (as their interaction with ozone is not clear yet), appropriate ozone therapy may bring new horizons for patients when all classically known methods of treatment have been completed, before assigning the patients for amputation.

Effect of vacuum sealing drainage combined with intermittent insulin flushing on expression of inflammatory factors and apoptosis factors in diabetic lower limb ulcer wound

Objective: To discuss the effect of vacuum sealing drainage combined with intermittent insulin flushing on the expression of inflammatory factors and apoptosis factors in diabetic lower limb ulcer wound. Methods: A total of 48 patients with diabetic lower limb ulcer who were treated in the Endocrine Department of the hospital between January 2016 and January 2017 were divided into the control group and research group by random number table, 24 cases in each group. Control group received vacuum sealing drainage, and research group received vacuum sealing drainage combined with intermittent insulin flushing. The differences in the expression of inflammatory factors and apoptosis genes in the wound exudate were compared between the two groups before and after treatment. Results: Before treatment, the differences in the inflammatory factor contents and apoptsis gene expression in wound exudate were not statistically significant between the two groups of patients. After treatment, inflammatory factors IL-6, IL-1β, TNF-α, CRP, VCAM-1 and FGF2 contents in wound exudate of research group were lower than those of control group;apoptosis gene Bcl-2 mRNA expression in wound exudate of research group was higher than that of control group while Bax, p53 and Fas mRNA expression were lower than those of control group. Conclusions: Vacuum sealing drainage combined with intermittent insulin flushing can effectively reduce the local inflammatory response and promote the granulation cell proliferation in wound of patients with diabetic lower limb ulcer.

Diabetic foot ulcers:Classification,risk factors and management

Diabetic foot ulceration is a devastating complication of diabetes that is associated with infection,amputation,and death,and is affecting increasing numbers of patients with diabetes mellitus.The pathogenesis of foot ulcers is complex,and different factors play major roles in different stages.The refractory nature of foot ulcer is reflected in that even after healing there is still a high recurrence rate and amputation rate,which means that management and nursing plans need to be considered carefully.The importance of establishment of measures for prevention and management of DFU has been emphasized.Therefore,a validated and appropriate DFU classification matching the progression is necessary for clinical diagnosis and management.In the first part of this review,we list several commonly used classification systems and describe their application conditions,scope,strengths,and limitations;in the second part,we briefly introduce the common risk factors for DFU,such as neuropathy,peripheral artery disease,foot deformities,diabetes complications,and obesity.Focusing on the relationship between the risk factors and DFU progression may facilitate prevention and timely management;in the last part,we emphasize the importance of preventive education,characterize several of the most frequently used management approaches,including glycemic control,exercise,offloading,and infection control,and call for taking into account and weighing the quality of life during the formulation of treatment plans.Multidisciplinary intervention and management of diabetic foot ulcers(DFUs)based on the effective and systematic combination of these three components will contribute to the prevention and treatment of DFUs,and improve their prognosis.

Therapeutic effect of autologous concentrated growth factor on lower-extremity chronic refractory wounds:A case report

BACKGROUND Management of chronic refractory wounds is one of the toughest clinical challenges for surgeons.Because of poor blood supply,less tissue coverage,and easy exposure,the lower leg is a common site for chronic refractory wounds.The current therapeutic regimens often lead to prolonged hospital stay and higher healthcare costs.Concentrated growth factor(CGF)is a novel blood extract that contains various growth factors,platelets,and fibrins to promote wound healing process.However,there has been little research reported on the treatment of lower extremity wounds with CGF.CASE SUMMARY A 37-year-old man,without any past medical history,presented an ulcerated chronic wound on his right lower leg.The skin defect exhibited clear boundaries,with a size of 2.0 cm×3.5 cm.The depth of wound was up to the layer of deep fascia.Staphylococcus aureus was detected by bacterial culture.The final diagnosis was right lower extremity ulcers with infection.Cefathiamidine,silver sulfadiazine,and mupirocin cream were applied to control the infection.CGF gel was prepared from the patient’s blood sample,and was used to cover the wound after thorough debridement.The skin wound was successfully healed after three times of CGF treatment.CONCLUSION CGF displays an excellent wound healing promoting effect in patients with lowerextremity chronic refractory wounds.

Investigation and analysis of lower extremity arterial disease in hospitalized elderly type 2 diabetic patients

Background:The risk of lower extremity arterial disease (LEAD) is increased in diabetic patients.LEAD in diabetic patients occurs earlier and is often more severe and diffuse;however,it is largely underdiagnosed and untreated.The purposes of this study were to investigate and analyze LEAD situation of hospitalized elderly type 2 diabetic patients.Methods:The ankle-brachial index (ABI) was used to screen LEAD in hospitalized elderly type 2 diabetic patients.The patients were divided into 5 groups based on the screening results:non-LEAD group and LEAD group;the LEAD group was divided into mild stenosis group,moderate stenosis group,and severe stenosis group.Results:The percentage of patients who had LEAD was 43%.Significant difference in age,diabetes duration,peak velocity,microalbuminuria,and vibratory sensory neuropathy was observed between patients with and without LEAD;regression analysis showed that urinary albumin and vibratory sensory neuropathy were independent risk factors for LEAD.Significant difference in age,body mass index (BMI),peak velocity,urinary albumin,and high-density lipoprotein cholesterol (HDL-C) was observed between mild stenosis group,moderate stenosis group,and severe stenosis group;regression analysis showed that urinary albumin,BMI,and HDL-C were independent risk factors for accelerating vascular stenosis.Conclusions:The incidence of LEAD in hospitalized elderly type 2 diabetic patients is high;age,diabetes duration,peak velocity,BMI,urinary microalbumin,vibratory sensory neuropathy,and HDL-C are the maior risk factors for LEAD.Active control of risk factors is helpful to reduce or delay LEAD.

Effect of combining music media therapy with lower extremity exercise on elderly patients with diabetes mellitus

Objective:To evaluate the compliance with lower extremity exercise and blood circulation in the feet of elderly diabetics following a combination of music media therapy and a lower extremity exercise regimen.Method:The 72 elderly diabetic patient subjects were divided into two groups:control group(n=38)and intervention group(n=34).Both groups were exposed to the same comprehensive therapy to control glucose levels.While the control group was given the lower extremity exercise,the intervention group received the extremity exercise in addition to the music media.Result:After three months of intervention,the adherence to the lower extremity exercise regimen in the intervention group was significantly higher than that of the control group(p<0.05).Additionally,following six months of treatment,both the dorsal artery peak values and ankle-brachial indices(ABIs)showed significant differences between the control and intervention groups(p<0.05).Conclusion:Music media treatment combined with lower extremity exercise can both significantly increase the extent of exercise compliance of elderly patients suffering from diabetes mellitus,as well as improve blood circulation in their feet.

To Explore the Relationship between Lower Extremity Vascular Sclerosis and Osteoporosis in Elderly Men with Type 2 Diabetes Mellitus

Objective: To investigate the correlation between lower extremity vascular sclerosis and osteoporosis in elderly men with type 2 diabetes mellitus. Methods: A total of 359 elderly male patients with type II diabetes hospitalized in the First Affiliated Hospital of Chongqing Medical University from January 2018 to June 2023 were retrospectively collected. According to the BMD (Bone Density Value), the patients were categorized into osteoporotic (T ≤ -2.5, n = 248) and non-osteoporotic groups (T > -2.5, n = 111). T test and Chi-square test were used to evaluate the differences in clinical data, biochemical markers and ABI between two groups. Multivariate logistic regression was used to analyze the risk factors of osteoporosis in elderly men with type 2 diabetes mellitus. Results: Compared with the non-osteoporotic group, the differences in diabetes course, systolic blood pressure, ABI, BMI, uric acid, triglyceride, and HDL in the osteoporotic group were statistically significant (P < 0.05). Logistic multivariate regression analysis showed that lower extremity vascular sclerosis was an independent risk factor for osteoporosis in elderly men with type 2 diabetes mellitus (P Conclusion: Atherosclerosis of the lower extremities in elderly men with T2DM is closely related to osteoporosis, and can lead to a decrease in bone mass, and an increase in osteoporosis.

Lower Extremity Ulcers in Patients with Systemic Sclerosis

Introduction: Cutaneous manifestations of systemic sclerosis (SSc) include skin ulceration;4% - 12% of patients with SSc develop lower extremity ulcers of various etiologies. Limited data, significant morbidity, and substantial cost of wound care led us to undertake this study to describe and identify risk factors. Methods: After Institutional Review Board approval, we identified 30 patients with SSc and lower extremity ulcers over a 10-year period at a single center with an SSc clinic, which were included in a descriptive analysis. Results: Median age of onset of lower extremity ulcers was 59.5 years (range 20 - 84). Ninety percent of patients were female, 60% were Caucasian, 63% had limited SSc, 13% diffuse SSc and 23% an overlap syndrome. Immunomodulators or steroids were prescribed in 53%;hypercoagulable state identified in 16%. Ulcers were attributed to venous stasis (27%), SSc (20%), trauma (20%), arterial disease (17%), and multifactorial/unknown (17%). In patients with ulcers attributed to SSc, age at onset was lower (45.5 vs 59.5 years). Biopsies generally did not contribute to management. Multidisciplinary treatment was routine;20% required amputation, 10% endovascular intervention, 20% frequent surgical debridement, 10% hyperbaric oxygen, 26% local treatment and antibiotics and 13% received immunosuppression for wound treatment. Conclusion: Lower extremity ulcers are a serious clinical problem in patients with SSc. The clinical exam, venous dopplers, ankle-brachial indices and assessment of vascular risk factors helped define causality. In younger patients, ulcers were more frequently attributed to SSc and these patients were more likely to be on immunosuppressants/DMARDS, possibly indicating severe phenotype of SSc.

Paper Clinical Value of Color Doppler Ultrasonography in Diagnosis of Lower Extremity Arterial Disease of Diabetes Patients

Objective: To evaluate the diagnostic value of color Doppler ultrasound in the diagnosis of diabetic lower extremity vascular diseases. Methods: 48 patients with diabetic lower extremity vascular disease admitted in our hos-pital from September 2018 to September 2019 were included in the study and divided into the observation group, and another 48 patients with the same period of health examination in our hospital were included in the study and divided into the control group. Both groups used color Doppler ultrasound to detect the blood flow of lower extremity vessels. The incidence of blood flow, vascular diameter and stenosis, occlusion and arteriosclerosis of the lower extremity were observed. Results: The blood flow and vascular di-ameter of the lower extremity in the observation group were significantly lower than those in the control group (p < 0.05). The incidence of vascular stenosis, vascular occlusion, thrombus, intimal thickening and plaque in the observation group was 85.42%, 22.92%, 10.42% and 93.75% respectively, which was significantly higher than that in the control group was 10.42%, 0.00%, 0.00% and 14.58% (p < 0.05). The incidence of lower extremity vascular lesions in the observation group was significantly higher than that in the control group (p < 0.05). Conclusion: Color Doppler ultrasound is of high diagnostic value in the diagnosis of diabetic lower extremity vascular diseases, and can be used to determine the blood flow of the lower extremity and the inner diameter of popliteal artery, thigh artery, dorsalis pedis artery and so on. At the same time, it can also clearly show the specific situation of vascular occlusion, arteriosclerosis and thrombosis, which is of great signif-icance for the prevention and diagnosis of lower extremity vascular lesions, and can provide the basis for the treatment of lower extremity vascular lesions.

Effect of Buerger’s Exercises on Improving Peripheral Circulation: A Systematic Review

The aim of this study was to systematically review the evidence for the effectiveness of Buerger’s exercise on the peripheral circulation or diabetic foot ulceration. A systematic search and 18 electronic databases were conducted. The intervention was predominantly focused on Buerger’s exercise as an outcome. Due to high heterogeneity, data were synthesized in a narrative format rather than by statistical methods. Nine studies that covered 592 participants were selected in the analysis, of which 8 of the 9 found an effect of Buerger’s exercise on peripheral circulation. The positive effects were indicative of improving blood flow, walking ability, reducing necrosis, reducing venous embolism, pain, swelling, cyanosis and the bed-rest times. However, the study design and quality appraisal were limited to Jadad score 2 and the sample size was small. Findings provide some evidence of the beneficial effects of Buerger’s exercises. It was seen as a low cost and low risk physical activity that most diabetic patients could undertake at home. This review highlighted a need for further investigation of standardized procedures of Buerger’s exercises. More high quality studies on the prevention of diabetic foot are required regarding Buerger’s exercises.
