Impact of soft tissue around the knee on the efficacy of extracorporeal shockwave therapy in knee osteoarthritis.

Knee osteoarthritis (KOA) is the leading cause of knee pain in middle-aged and older individuals. Extracorporeal shockwave therapy (ESWT) has been applied to treat patients with KOA to reduce pain and improve function. Patients (n = 123) diagnosed with KOA who received ESWT were selected to participate in this study, and were grouped according to their body mass index (BMI).

Intra-articular injection of placental mesenchymal stromal cells ameliorates pain and cartilage anabolism/catabolism in knee osteoarthritis.

Knee Osteoarthritis (kOA), the most common joint degenerative disorder, lacks effective therapeutics. Placenta-derived mesenchymal stromal cells (PMSCs) are effective in tissue repairing and generation, which have potential in treating kOA. This study aimed to determine the anti-kOA efficacy of PMSCs and to explore its action mode.

β-tricalcium phosphate/gelatin composite scaffolds incorporated with gentamycin-loaded chitosan microspheres for infected bone defect treatment.

The repair of infected bone defects remains a clinical challenge. Staphylococcus aureus is a common pathogenic micro-organism associated with such infections. Gentamycin (GM) is a broad spectrum antibiotic that can kill S.

Effects of sintering temperature on surface morphology/microstructure, in vitro degradability, mineralization and osteoblast response to magnesium phosphate as biomedical material.

Magnesium phosphate (MP) was fabricated using a chemical precipitation method, and the biological performances of MP sintered at different temperatures as a biomedical material was investigated. The results indicated that the densification and crystallinity of MP increased as the sintering temperature increased. As the sintering temperature increased, the degradability of MP in PBS decreased, and the mineralization ability in SBF significantly increased.

Development of a bioactive composite of nano fluorapatite and poly(butylene succinate) for bone tissue regeneration.

The development of a bioactive nanocomposite for bone replacement has gained much interest in the field of bone grafting. In this study, a nano fluorapatite (n-FA)-poly(butylene succinate) (PBS) bioactive composite was fabricated using a co-solution method. The results showed that the n-FA-PBS composite had improved hydrophilicity, compressive strength and an elastic modulus, which were obviously higher than those of PBS alone.

[The application of external fixation for the treatment of supracondylar femoral fracture after total knee replacement].

Objective: To explore the external fixation for treatment of supracondylar femoral fractures after total knee replacement.

Methods: From June 2005 to July 2007, 7 cases of supracondylar femoral fracture after total knee replacement were treated with external fixation included 4 males and 3 females with an average age of 71 years ranging from 55 to 85 years. The fracture healing were observed and the knee function were evaluated by the HSS scoring.

Effect of neurotrophin-3 genetically modified olfactory ensheathing cells transplantation on spinal cord injury.

Transplantation of olfactory ensheathing cells (OECs) has emerged as a very promising therapy for spinal cord injury (SCI). Also, local delivery of NT-3 can counteract pathological events and induce a regenerative response after SCI. Supplement of exogenetic NT-3 might be a new approach to SCI repair.

[Controlled clinical trials of initial observation on therapeutic effects of moxibustion for osteoarthritis of the knee: multi-center clinical effect].

Objective: To compare therapeutic effects between moxibustion and infrared therapy for the treatment of knee osteoarthritis.

Methods: From January 2007 to June 2008 period, 65 patients with knee osteoarthritis were divided into treatment and control groups randomly uniform random number table generated from SAS statistical software. Among 35 patients in the treatment group, 17 patients were male and 18 patients were female, ranging in age from 45 to 75 years, with an average of (61.

[Evaluation of the clinical effect of knee osteoarthritis treated with moxibustion according to WHOQOL-BREF].

Objective: To investigate and research WHOQOL-BREF evaluation of the clinical effect of application of moxibustion for treatment of knee osteoarthritis, to provide clinical according for the treatment.

Methods: From January 2007 to June 2008, 90 cases of knee osteoarthritis were randomly divided into treatment group and control group. In treatment group there were 45 cases included 16 males and 29 females with an average age of (62.

Intradural lysis and peripheral nerve implantation for traumatic obsolete incomplete paralysis.

Twenty-eight patients who suffered traumatic obsolete incomplete paralysis were treated with intradural lysis and peripheral nerve implantation by a microsurgery technique. The endorachis was opened and the fibrous bands adhering to the spinal cord from the arachnoid, pia mater spinalis, ligamenta denticulatum, and the initial part of the nerve root were completely relieved. The abnormal spinal cord was then opened by three to six incisions, which were each 0.

Restoration of stepping-forward and ambulatory function in patients with paraplegia: rerouting of vascularized intercostal nerves to lumbar nerve roots using selected interfascicular anastomosis.

The objective of this study is to restore stepping-forward and ambulatory function in paraplegic patients with chronic injuries. Two to four normal vascularized intercostal nerves above the spinal cord injury site were obtained by cutting in the distal end at the midclavicular line. The proximal ends were disconnected from the levatores costarum.

Ehrlichia-like organism gene found in small mammals in the suburban district of Guangzhou of China.

The 16S rRNA gene of Ehrlichia genus was examined from the blood and spleen of 26 wild small mammals that were captured at a canine feed lot where the first case of canine ehrlichiosis was found in south of China in 1998. Samples (3 blood and 1 spleen) from Rattus norvegicus were positive by polymerase chain reaction. The amplimers were then cloned and sequenced.
