Methods Sixty patients with a diabetic foot wound area ≤6 cm2 were treated in our hospital from June 2009 to June 2010. There were 41 males and 19 females with their ages ranged from 49 to 80 years old, averaging at 58. The course of diabetes ranged from 4 to 20 years, and diabetic foot 2 to 12 weeks. According to diabetic foot Wagner grading standards, the patients were classified as grade Ⅰ, Ⅱ and Ⅲ (with 20 patients for each grade). They were randomly divided into the treatment group and the control group with 30 patients in each group and for both groups, there were 10 patients for each Wagner grade. There were no statistically significant differences between the two groups of patients in gender, age, duration of the disease course, and wound area (Pgt;0.05) so that they were comparable. All patients were routinely offered with insulin or other medicine to control blood sugar level, and at the same time they accepted anti-inflammatory, microcirculation improving and nutrition supporting treatments. Zinc hyaluronate was added to the treatment of the patients in the treatment group, while the control group underwent conventional treatment. Wound healing condition was observed 4 and 8 weeks after the beginning of the treatment. Results At week eight, the cure rate for the treatment group was 53.3%, and the total effective rate was 96.7%; the two numbers for the control group were respectively 30.0% and 60.0%. There was a significant difference between the two groups in the total effectiveness (Plt;0.05). The cure rate and total effective rate for grade Ⅱ and Ⅲ wound in the treatment group were better than those in the control group (Plt;0.01). Coagulant time for the treatment group and the control group was respectively (23.25±8.52) days and (29.16±9.20) days with a significant difference (Plt;0.05). No statistical difference was found in the bacteria cultures between the two groups after treatment. Conclusions Using zinc hyaluronate in diabetic foot treatment can obviously protect the wound and promote wound healing. It is a good choice for diabetic foot wound healing.
ObjectiveTo review the research progress of adrenergic β-antagonists on wounds and diabetic chronic cutaneous ulcers healing in recent years, and to investigate its application prospect in diabetic foot ulcer (DFU).MethodsThe latest literature about the role of adrenergic β-antagonists in wounds and diabetic chronic cutaneous ulcers healing was extensively reviewed, and the mechanisms of adrenergic β-antagonists for wounds and its potential benefit for DFU were analyzed thoroughly.ResultsThe adrenergic β-antagonists can accelerate the wound healing. The possible mechanisms include accelerating re-epithelialization, promoting angiogenesis, improving neuropathy, and regulating inflammation and growth factors, etc. At present clinical research data showed that the adrenergic β-antagonists may be an adjuvant treatment for diabetic chronic cutaneous ulcers.ConclusionAdrenergic β-antagonists maybe promote the healing of wounds and diabetic chronic cutaneous ulcers. However, more long-term follow-up and high-quality randomized control studies are needed to further verify their efficacy and safety for DFU.

ObjectiveTo summarize the effectiveness and experience of Wanger grade 3-5 diabetic foot treated with vacuum sealing drainage (VSD) combined with transverse tibial bone transport.MethodsBetween March 2015 and January 2018, 21 patients with refractory diabetic foot who failed conservative treatment were treated with VSD combined with transverse tibial bone transport. There were 15 males and 6 females, aged 55-88 years (mean, 65 years). The diabetes history was 8-15 years (mean, 12.2 years). The duration of diabetic foot ranged from 7 to 84 days (mean, 35.3 days). The size of diabetic foot ulcer before operation ranged from 2 cm×2 cm to 8 cm×5 cm. According to Wanger classification, 8 cases were rated as grade 3, 11 cases as grade 4, and 2 cases as grade 5. Among the 21 cases, angiography of lower extremity before operation was performed in 5 cases, CT angiography of lower extremity in 16 cases, all of which indicated that the arteries below the knee were narrowed to varying degrees and not completely blocked. Preoperative foot skin temperature was (29.28±0.77)℃, C-reactive protein was (38.03±31.23) mg/L, leukocyte count was (9.44±2.21)×109/L, and the visual analogue scale (VAS) score was 6.8±1.5, and ability of daily living (Barthel index) was 54.3±10.3.ResultsAfter operation, 2 patients with Wanger grade 4 and smoking history failed treatment and had an major amputation (amputation above ankle joint) at 30 days and 45 days after operation, respectively. One patient with Wanger grade 5 and chronic heart failure died of cardiac arrest at 60 days after operation. The remaining 18 patients were followed up 6-24 months (mean, 9.2 months). The external fixator was removed at 40-62 days after operation, with an average of 46 days. All the wounds healed, with a healing time of 50-120 days (mean, 62.5 days). The pain of 18 patients’ feet was relieved obviously, and there was no recurrence of ulcer in situ or other parts. There was no complication such as tibial fracture and ischemic necrosis of lower leg skin after operation. After ulcer healing, the foot skin temperature was (30.86±0.80)℃, C-reactive protein was (22.90±18.42) mg/L, VAS score was 2.4±1.2, and Barthel index was 77.3±4.6, all showing significant differences when compared with preoperative ones (P<0.05); the leukocyte count was (8.91±1.72)×109/L, showing no significant difference (t=1.090, P=0.291).ConclusionVSD combined with transverse tibial bone transport can effectively promote the healing of Wanger grade 3-5 diabetic foot wounds, but smokers, unstable blood glucose control, and chronic heart failure patients have the risk of failure.
ObjectiveTo explore the relationship of the level of inflammation and nutritional status with the occurrence and prognosis of refractory diabetic foot.MethodsA total of 70 patients with refractory diabetic foot between August 2015 and August 2017 were randomly selected as the observation group. Another 70 patients with diabetes mellitus (without foot ulcer) who visited the hospital in the same period were set as the control group. The observation group was subgrouped into the non-amputation group and the amputation group according to the follow-up endpoint events, and into the grade Ⅲ, Ⅳ, and Ⅴ groups according to Wagner classification method. The blood levels of inflammatory markers and nutritional markers between groups were compared.ResultsIn the observation group, vascular cell adhesion molecule-1 (VCAM-1), fibroblast growth factor 2 (FGF2), fibrinogen (FIB), tumor necrosis factor-α (TNF-α), interleukin (IL)-6, IL-18, lipoprotein phospholipase A2 (LP-PLA2), C-reactive protein (CRP) levels were significantly higher than those in the control group, and albumin (ALB), prealbumin (PA), and transferrin (TRF) levels were significantly lower than those in the control group, with statistically significant differences (P<0.01). The blood levels of FGF2, FIB, IL-6, IL-18, LP-PLA2, and CRP in the amputation group were significantly higher than those in the non-amputation group, and the levels of TRF, ALB, and PA were significantly lower than those in the non-amputation group (P<0.01). There were statistically significant differences in the levels of FGF2, FIB, IL-6, IL-18, LP-PLA2, CRP, TRF, ALB, and PA in patients with diabetic foot with different Wagner grades (P<0.05). The result of multiple logistic regression analysis showed that IL-6 [odds ratio (OR)=1.487, 95% confidence interval (CI) (1.023, 2.120), P<0.001], IL-18 [OR=1.274, 95%CI (1.052, 1.665), P<0.001], LP-PLA2 [OR=1.478, 95%CI (1.126, 1.789), P<0.001], and CRP [OR=2.085, 95%CI (1.574, 2.782), P<0.001] were independent risk factors for the occurrence of refractory diabetic foot, and TRF [OR=0.645, 95%CI (0.002, 0.898), P<0.001], ALB [OR=0.838, 95%CI (0.429, 0.923), P<0.001], and PA [OR=0.478, 95%CI (0.201, 0.984), P<0.001] were independent protective factors for the occurrence of refractory diabetic foot.ConclusionIn the clinical treatment of diabetic foot, we should pay attention to the monitoring of the level of inflammatory factors and nutritional status, and it is necessary to timely carry out anti-inflammatory treatment and appropriate nutritional support treatment.
Diabetic foot is one of the serious complications of diabetic patients. It is caused by diabetes combined with different degrees of lower extremity vascular lesions and neuropathy, and the wound can not heal for a long time. The serious results can cause bone marrow infection, bone destruction, and have high disability and death rate. At present, there are various treatment methods for diabetic foot chronic wound. On the basis of internal medicine controlling blood sugar, anti infection, lowering blood lipid, improving microcirculation and nourishment nerve, the surgical method is adopted, including the debridement of the necrosis in a short time to prevent the infection from spreading; maggot biological debridement and ozone chemical debridement will promote the growth of granulation tissue while controlling infection. Skin grafting, skin flap transplantation, skin distraction closure can be used to repair soft tissue defects, or fat transplantation, platelet-rich plasma, and rich blood are used for the refractory wound after infection control. In patients with diabetic foot, the reconstruction of lower limb blood supply is beneficial to the recovery of chronic ischemic wounds. It is feasible to improve the blood supply of the lower extremities, improve the blood supply of the lower extremity artery bypass grafting, and improve the microcirculation of the peripheral vessels around the lower extremities. Lower extremity vascular bypass pressure perfusion therapy for vascular network expansion, tibia lateral moving technique for lower limb microcirculation reconstruction. For diabetic foot ulcer caused by peripheral neuropathy, such as Charcot foot, while the application of external fixator, total contact cast technology of affected foot for reducing treatment to promote wound healing; the preparation of orthopedic shoes can play a maximum protective effect on the healing of diabetic foot wound healing.
