Objective: Aim: To improve the results of treatment of patients with chronic wounds of the lower extremities by using complex treatment, including surgical interventions, VAC- therapy, as well as studying the effect of negative pressure on bacterial films of wounds, based on microbiological examination and immune-histochemical data.
Patients And Methods: Materials and Methods: During the period from 2019 to 2023 at the department's clinic, 68 patients with chronic wounds of the lower extremities were examined and treated. These are mainly women (n=63) aged from 35 to 80 years.
Results: Results: Complete wound healing was achieved in all patients. In 79% of patients, the transplanted skin graft took root completely. Partial lysis was observed in 17%, requiring repeated operations. In 4%, the wounds healed without surgery. The VAC- therapy we used prevented the restoration of the biofilm and prevented further infection of the wound. After complex treatment, we observed positive dynamics of clinical and immunological parameters. Indicators of T-cell immunity (CD3+, CD4+, CD19+) were restored, the level of CIC significantly decreased and the level of IgM increased. The level of interleukins on day 21 showed a tendency towards normalization.
Conclusion: Conclusions: A modern integrated approach gives the chance to radically solve the problems of healing chronic wounds. VAC- therapy in combination with surgical treatment and antibacterial therapy prevented the restoration of biofilm and further infection of wounds, which led to the wound healing in 100% cases.

The challenges associated with prolonged healing or non-healing of chronic diabetic wounds contribute significantly to the increased incidence of lower limb amputation. A pivotal factor in the impediment of healing is the reduced production of endogenous nitric oxide (NO) due to the hyperglycemic microenvironment typical of chronic diabetes. While both endogenous and exogenous NO have been shown to promote the healing process of diabetic wounds, the direct application of NO in wound management is limited due to its gaseous nature and the risk of explosive release.

Osteoarthritis (OA) is the most common chronic degenerative joint disease, characterized by cartilage damage, synovial inflammation, subchondral bone sclerosis, marginal bone loss, and osteophyte development. Clinical manifestations include inflammatory joint pain, swelling, osteophytes, and limitation of motion. The pathogenesis of osteoarthritis has not yet been fully uncovered.

This study verified the efficacy of the Rheocarna, a novel apheresis device, for no-option CLTI or poor-response CLTI after revascularization.
Methods And Results: This multicenter retrospective observational study analyzed 221 patients (221 limbs) with no- or poor-option CLTI (mean [±SD] age 71±10 years; males, 70.
Antheraea pernyi silk nanofibrils with inherent RGD motifs accelerate diabetic wound healing: A novel drug-free strategy to promote hemostasis, regulate immunity and improve re-epithelization.

The chronic inflammation and matrix metalloprotease (MMP)-induced tissue degradation significantly disrupt re-epithelization and delay the healing process of diabetic wounds. To address these issues, we produced nanofibrils from Antheraea pernyi (Ap) silk fibers via a facile and green treatment of swelling and shearing. The integrin receptors on the cytomembrane could specifically bind to the Ap nanofibrils (ApNFs) due to their inherent Arg-Gly-Asp (RGD) motifs, which activated platelets to accelerate coagulation and promoted fibroblast migration, adhesion and spreading.

The disease burden of air pollution (AP) has been well-documented, yet few studies have explored its economic burden. Retrieving disease burden data from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2021, this study constructed a cost-of-illness (COI) model to estimate China's economic burden of AP in 1990 and 2021 and to identify national and provincial differences, then, an age-period-cohort (APC) model was adopted to estimate trends to 2050. Results demonstrated a serious load of AP, emphasizing the necessity for intervention.
