Chinese Medicine as Supporting Therapy for Psoriasis: Past, Present, and Future.

Psoriasis is a chronic skin disease and an important health concern. Western medicine and therapies are the main treatment strategies for psoriasis vulgaris (PV); however, the overall prognosis of patients with PV is still poor. Therefore, PV prevention is especially crucial. Chinese medicine (CM) has a long history of treating psoriasis, and it has unique wisdom in different cognitive angles and treatment modes from modern medicine. In this review, we first summarized the herbs and ancient CM formulas that have therapeutic effects on PV. Second, the research status and obstacles to the current development of CM in modern medicine were reviewed. Finally, the future of CM in the context of precision medicine and integrated medicine was discussed. After a detailed reading of the abundant literature, we believe that CM, through thousands of years of continuous development and clinical practice, has achieved high effectiveness and safety for PV treatment, despite its surrounding controversy. Moreover, precise analyses and systematic research methods have provided new approaches for the modernization of CM in the future. The treatment of PV with CM is worth popularizing, and we hope it can benefit more patients.

One-stage revision arthroplasty in a patient with ochronotic arthropathy accompanied by joint infection: A case report.

BACKGROUND: Ochronotic arthropathy (OcA) is a rare disease, which is caused by the accumulation of homogentisic acid in the joint. Patients with OcA have obvious joint pain and the disease progresses rapidly, eventually resulting in disability. Arthroplasty is an efficacious treatment in patients with OcA. However, when OcA patients have joint infection, is joint replacement an option? In the present report, we performed total knee arthroplasty in a patient with OcA and knee infection under the guidance of one-stage revision theory. CASE SUMMARY: A 64-year-old male was referred to our hospital due to severe left knee pain with limited mobility for 2 years. On physical examination, the patient was found to have dark brown pigmentation of the sclera and auricle. Laboratory test results showed elevations in C-reactive protein level (65.79 mg/L) and erythrocyte sedimentation rate (90.00 mm/h). The patient underwent debridement of the left knee joint, during which the cartilage surface of the knee joint was found to be black-brown in color. Bacterial culture of synovial fluid revealed Achromobacter xylosoxidans. We then carried out arthroplasty under the guidance of the theory of one-stage revision. After surgery, the patient's left knee joint pain disappeared and function recovered without joint infection. CONCLUSION: OcA accompanied by joint infection is rare. One-stage revision arthroplasty may be a treatment option for this disease.

Production of an in vitro-derived deletion mutation of Brevibacillus laterosporus by constructing a homology-driven integration vector.

In this study, a homology-driven integration vector and electroporation system was developed to delete a protease gene in the pathogenic bacterium Brevibacillus laterosporus strain G4. Furthermore, an in vitro protease-deficient mutation was generated by introducing the integration vector with a 445-bp protease BLG4 fragment into B. laterosporus chromosomal target via homologous recombination. The BLG4-deficient mutant showed a significant drop in protease activity as compared to the wild-type G4 strain, but had a slight effect on bacterial growth and sporulation. The results revealed that the developed method can become an important tool for studying the molecular pathogenesis mechanisms of B. laterosporus.
