OBJECTIVE To review the physiological function of sodium hyaluronate in joints and its clinical applications. METHODS Many literatures were reviewed and analysed on therapeutic mechanism and the application foreground of sodium hyaluronate. RESULTS Extrinsic sodium hyaluronate plays an important role in improving synovial fluid and protecting cartilages as well as suppressing inflammation, so it is used in the treatment of joint diseases such as knee osteoarthritis, rheumatoid arthritis or temporomandibular osteoarthritis. CONCLUSION Sodium hyaluronate possesses a good applied prospect in joint diseases.
Objective To evaluate the clinical effect of percutaneous laser disc decompression (PLDD) in the treatment of cervical disc herniation. Methods From March 2003 to December 2005, 47 patients with cervical disc herniation(96 cervical disc) were treated with PLDD. There were 25 males and 22 females with an average age of 56 years, ranging from 37 to72 years. The lesion were located at the levels of C3,4 in 20 discs, C4,5 in 27 discs, C5,6 in 31 discs, C6,7 in 18 discs. The laser fiber was introduced into the center of the herniated disc space by percutaneous puncture from anterior neck surface under fluoroscopic guidance. Laser reduced the intradisc pressure through the vaporization of disc nucleu. The adopted laser was semiconducted with a wavelength of 810 nm. Each laser output power was15 W with 1 s emission and 2 s interval. The total laser output power was decided depending on the degenerative degree of the disc and the reactive process of heat, ranging from 300 to 1 000 J.Results Of 47 patients,42 were followed up for 3 to 31 months (mean 13 months). The clinical evaluation was classified as excellent in 18 cases (42.9%), good in 14 cases (33.3%), fair in 6 cases (14.3%) and poor in 4 cases (9.5%). The general response rate was 90.5%. The excellent and good rate was 76.2%. No complications occurred. Conclusion PLDD can relieve the symptoms and signs of patients suffering from cervical disc herniation with less complication. The manipulation of PLDD is easy, safe and mini-invasive.
European system for cardiac operative risk evaluation(EuroSCORE) is one of the widely used and influential cardiac surgery risk assessment system. It was originally used to predict the quantitative score of probability of death after cardiac surgery. After that, it has been developed to predict long-term mortality and survival rate, ICU residence time, treatment costs, main complications and so on. EuroSCORE Ⅱ is the latest version, which is more accurate in predicting mortality, long term survival rate than the old one. But there are also some limitations as predicting limited range of the end, underestimating the mortality of critically endangered patients, lacking adequate preoperative risk factors and so on. This review article focuses on the production, development and clinical application of EuroSCORE.
Median nerve electrical stimulation is a common peripheral nerve electrical stimulation treatment technology in clinic. With simple operation, it has been widely used in clinical to promote coma after craniocerebral trauma, relieve pain, improve cognition, Parkinson’s disease and so on. However, its mechanism has always been a hot topic and difficult part. At present, there are a large number of clinical efficacy studies and animal experiments of median nerve electrical stimulation at home and abroad. This article reviews the clinical application and animal experiments of median nerve electrical stimulation in recent years, and summarizes its mechanism, hoping to contribute to relevant clinical applications and research.
ObjectiveTo summarize the application and research progress of robotic-arm in total knee arthroplasty (TKA).MethodsRelevant literature at home and abroad was extensively reviewed to analyze the advantages and disadvantages of robotic-arm assisted TKA (RATKA).ResultsAccurate reconstruction of lower extremity alignment and rotation alignment, accurate osteotomy and implant prosthesis in TKA are very important to improve the effectiveness and prolong the life of the prosthesis. Traditional TKA deviations occur in key links such as osteotomy due to operator’s operation. RATKA solves the above problems to a certain extent and can assist accurate osteotomy and implant prosthesis, and protect the soft tissues around the knee joint. Patients’ satisfaction after RATKA is high, and the operator’s learning curve is shorter, which improves the efficiency of the operation. But it also has disadvantages such as prolonged operation time, increased complications and medical costs.ConclusionPreliminary clinical application studies have shown that RATKA has satisfactory effectiveness, but its definite advantages compared with traditional TKA need to be confirmed by a large number of randomized controlled trials and long-term follow-up.
he fascia lata substitute valve operation was performed for curing the supperficial varieositycaused by the deep vein incompotence of the lower extremity basing on the study of the sources ofblood supply and the vascular distribution features of the fascia lata. The fascia lata subetitute vein valve operations were done on three males with the age rangingbetween 22 and 44 years old, and the rerelts were satisfactory 2 and 6 months after oporation.
The postoperative symptom burden in patients with lung cancer is severe and adversely impairs their quality of life. Symptom management is the cornerstone of medical care. Patient-reported outcome (PRO)-based symptom management is being increasingly recognized as the best "patient-centered care" model in clinical practice. However, the precise implementation of this model in patients undergoing lung cancer surgery is hindered by the lack of a lung cancer surgery-specific scale, implementation standards, clinical application parameters and high-quality researches. The use of a precise and simple PRO scale and an electronic PRO platform may greatly improve the feasibility of implementing this model. Currently, the application of PRO-based symptom management in lung cancer surgery is still being explored and needs to be improved in clinical research and practice.
