Mid-to-late stage ankle arthritis is a chronic degenerative disease that is extremely common in clinical practice.It is characterized by significant cartilage degeneration and subchondral bone sclerosis,accompanied by the formation of osteophytes around the joint,often leading to joint deformity.This condition causes severe pain in the patients during walking,severely restricts their activities,and affects their qualities of life.In recent years,with the continuous improvement of medical standards,the treatment methods for mid-to-late stage ankle arthritis have shown a diversified development trend.Non-surgical treatments primarily include activity restriction,orthotic devices,oral non-steroidal anti-inflammatory drugs(NSAIDs),and intra-articular injections of the talocrural joint.The surgical treatments primarily include joint distraction arthroplasty,periacetabular osteotomy,total ankle arthroplasty,and ankle arthrodesis.Tissue engineering therapy,as an emerging method,has also received considerable attention.This article systematically reviewed the selection principles and research progress of various treatment options for mid-to-late stage ankle arthritis,including traditional treatments,non-surgical treatments,surgical treatments,and tissue engineering treatments.By deeply analyzing the basic principles and advantages and disadvantages of each treatment method,and combining the latest research findings on clinical outcomes,a scientific and comprehensive clinical decision-making reference system was constructed to provide clearer and more comprehensive treatment choices for both doctors and patients,thereby effectively improving treatment outcomes and enhancing the quality of life for the patients.

BACKGROUND: Osteochondral lesion of the talus is a common disease of foot and ankle surgery, which has the characteristics of high morbidity, high misdiagnosis rate and difficulty in curing. OBJECTIVE: To summarize the etiology, clinical manifestations, diagnostic methods, clinical grading, treatment methods, and new therapies such as cell therapy and tissue engineering for osteochondral lesion of the talus.METHODS: The first author retrieved PubMed databases for relevant articles. The keywords were "talus, cartilage". Initially, 535 articles were retrieved, and finally 70 articles were included in result analysis. RESULTS AND CONCLUSION: Trauma is still considered to be the main pathogenic factor of talus cartilage injury. According to the imaging findings, the clinical scope of talar cartilage injury can be accurately determined. The clinically applied therapies have certain shortcomings and limitations. Tissue engineering-based therapies are currently the most likely to cure osteochondral lesion of the talus.

BACKGROUND:Stem cel is a kind of pluripotent cels with self-replication ability, which can differentiate into various cels under certain conditions. Furthermore, stem cels are rich in a variety of growth factors, which can induce the generation of vessels and nerves, and improve the blood supply of lower limbs, thereby achieving the treatment and preventions of lower limb ischemia OBJECTIVE:To summarize and compare the recent achievements in the theory and therapeutic efficacy of stem cels from different sources in the treatment of diabetic foot. METHODS:The first and second authors retrieved PubMed, Sciencedirect and Medline databases for relevant articles published from January 2000 to January 2015. The key words were “diabetic foot, pathogenesis, stem cel therapy” in English. Initialy, 186 articles were retrieved, and finaly 44 articles were included in result analysis. RESULTS AND CONCLUSION:Stem cels can be a new choice for the treatment of diabetic foot. After stem cel therapy, corresponding symptoms have been aleviated, including the generation of new blood vessels and the reshaping of the colateral vessels, the improvement of motor nerve conduction velocity and nerve reflex, the improvement of the sense of skin pain and temperature, and pain relief. It is stil unclear whether alogeneic stem cels are safe or not, but autologous stem cels, especialy bone marrow mesenchymal stem cels, can be better able to repair damaged vessels and nerves and restore the microcirculation of blood supply. Currently, we need to do more basic and clinical researches to solve the folowing problems: to confirm the effectiveness and safety of stem cel therapy for diabetic foot; to identify whether there is a difference in the differentiation and secretory activity between stem cels in diabetic patients and ordinary people; to give ful play to the treatment of diabetic foot.

ObjectiveTo investigate the characteristics of traumatic spinal cord injury (TSCI) urban inpatients of Tianjin in 2007. MethodsInpatients with TSCI of 8 hospitals in Tianjin in 2007 were reviewed. ResultsThere were 73 patients in total. Mean age was (51.34±14.597) years. Male∶Female was 3.56∶1. Falling, motor vehicle accidents （MVC） were the main causes of TSCI. The cervical spinal cord injuries were predominant. 26% were complete injury and 74% were incomplete. 6 cases were dead. Patients with ASIA grade D recover well. ConclusionFor the TSCI, the ages of patients increases and falling is the main cause.
