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.
Malnutrition is associated with many adverse clinical outcomes, including increased deaths and complications in perioperative period. The immunonutrition support plays an important role in the recovery process of patients with nutritional risk. Reasonable support can efficiently improve the condition of these cases and strongly suppress the inflammatory response. The immuno-nutrients include glutamine, ω-3 polyunsaturated fatty acids, arginine, nucleotides and so on. More and more evidences show that different kinds of immuno-nutrients play a regulatory role in metabolism and inflammatory response in patients with different disease stages and courses, and affect clinical outcomes and prognosis. Nowadays, there is an urgent need to standardize immunonutrition support in clinical work. In this paper, the related literatures about immunonutrition in recent years were reviewed. Our goal is to reduce the number of irregularities in the nutrition support practice, and to help nutritional risk patients achieve better clinical outcomes.
Kinesio taping is a technique which applies elastic patches on the body surface in a specific way to produce mechanical and neurophysiological effects, so as to support and protect the musculoskeletal system and improve the motor function of patients with various chronic musculoskeletal conditions. In addition, Kinesio taping has become popular among physiotherapists and showed certain clinical effect in the treatment of other fields such as neurological and pediatric rehabilitation in recent years, however its physiological mechanism is still unclear. This article puts forward some thinking and prospect on the basis of the review of clinical research and application of Kinesio taping, aiming to provide a reference for the research of clinical application and physiological mechanism of this technology.

ObjectiveTo explore the expression of Ki-67 antigen in the breast cancer tissues and to evaluate the relationship of the expression to biology behavior as well as prognosis of breast cancer.
MethodLiteratures about relation between Ki-67 and breast cancer were reviewed.
ResultsThe expression of Ki-67 in the breast cancer tissue was obviously higher than that in the adjacent to cancer tissue or normal breast tissue. The Ki-67 positive expression rate was positively correlated with pathology classification and clinical stage of breast cancer, the correlation was not consistent about the expression of Ki-67 and axillary lymph node metastasis of breast cancer.
ConclusionsKi-67 is a cell proliferation nuclear antigen related to cell cycle, and its expression changes along with the change of cell cycle, it has been employed as a reliable marker of cell proliferation. The expression of Ki-67 has an important significance in early diagnosis and guiding of neoadjuvant chemotherapy as well as prognosis of breast cancer.
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.
Objective To find out the recent progress in research of cl inical appl ication of fascia lata allograft. Methods The domestic and international articles were reviewed to summarize the princi pal properties, processing techniques, and various uses of fascia lata allograft. Results Histologically fascia lata is composed of parallel and compact bundles of collagen fibers with few cells and immunologically it is low-antigenic. After varied tissue processing and storage techniques, fascia lata, as the scaffold only with the extracellular matrix, has been used in cl inical practice and achieved good results, such as ophthalmology, urology, and orthopaedics. Conclusion Because of these unique properites in repairing defects and reconstructing functions, fascia lata allograft, as a natural biomaterial, is promising to be used in more aspects withthe development of the biomedical techniques.
Objective To summarize the latest development of the oral and maxillofacial reparative and reconstructive surgery. Methods The literature at home and abroad was reviewed and the main creative concepts in this field were summarized and analyzed. Results In the terms of the oral and maxillofacial reparative and reconstructive surgery, the significant achievements were made in the following aspects: transplantation of revascularized tissues, artificial materials, plateletrich plasma, distraction osteogenesis, microsurgery on fracture, arthroplasty, dynamic repair, and computerassisted design. Conclusion Based on the previous achievements, the oral and maxillofacial reparative and reconstructive surgery will have a further development, especially in the individualized treatment.
Objective
To investigate the clinical value and complication factors of percutaneous transthoracic needle biopsy (PTNB) guided by multislice computed tomography (MSCT).
Methods
From January 2013 to December 2016, 179 patients treated with MSCT-guided lung biopsy in the Affiliated Hospital of North Sichuan Medical College and Dianjiang People’s Hospital were reviewed. Occurrence rate and the influencing factors of complications were analyzed. Meanwhile, biopsy findings and diagnostic accuracy rate were summarized.
Results
A total of 129 cases of lung cancer were detected under MSCT-guided percutaneous biopsy in 179 patients with a diagnostic accuracy of 93.30%. The correct rate of malignant tumor diagnosis was 92.14%. The main complications were pneumothorax, pulmonary hemorrhage, dyspnea and hemoptysis. Major risk factors of MSCT-guided PTNB complications included lesion size ≤ 2 cm, the shortest distance to the diaphragm ≤ 5 cm, puncture depth > 5 cm, pleural puncture angle > 50°, the puncture times ≥ 2, puncture time ≥ 20 minutes, age of patients > 60 years, and existence of pulmonary disease (P<0.05).
Conclusions
The clinical application value of MSCT-guided PTNB is high. Skilled puncture technique and appropriate puncture procedure are helpful to reduce complications.
Objective To review and evaluate the clinical application of autologous plateletrich gel (APG) in refractory chronic diabetic cutaneous ulcers. Methods The latest literature was extensively reviewed, and the potential mechanism of APG for healing diabetic cutaneous ulcers was discussed. Results APG accelerated the ulcer healing, especially in healing the refractory diabetic cutaneous ulcers, and the high-level growth factors from the platelet releasate were thought to be the major potential mechanism of the APG action. Conclusion APG can promote the healing of refractory chronic diabetic cutaneous ulcers. Topical haemotherapy withAPG may be considered an adjuvant treatment of a multidisciplinary process and may be useful to the effective therapy of cutaneous ulcers.
