RESUMO
Symptomatic spinal epidural hematoma (SSEH) following spinal surgery is rare but one of the serious complications. SSEH can leave devastating neurological consequences if missing the optimal timing for treatment. The early diagnosis of SSEH is critical to the neurologic recovery, and MRI examination can help to check the location and the scope of the hematoma and provide imaging information for surgical operation. The risk factors of SSEH can be divided into preoperative factors, intraoperative factors and postoperative factors. The occurrence of SSEH can be minimized by controlling the risk factors, exact hemostasis and reasonable perioperative management. Patients with mild paralysis can choose conservative treatment, while patients with severe or progressive nerve injury (manual muscle testing <3) and unendurable nerve root pain should choose to clean the hematoma and decompress the nerve as soon as possible.
RESUMO
BACKGROUND:Tougu Xiaotong Capsule (TGXTC) is a clinical prescription for the treatment of osteoarthritis;however, its mechanism has not been ful y elucidated. Urokinase-type plasminogen activator (uPA) system participating in the degradation of the extracel ular matrix of articular cartilage and hyperplasia of joint synovium plays an important role in the pathological process of osteoarthritis. OBJECTIVE:To investigate the effects of TGXTC medicated serum on the expression of uPA, uPA receptor (uPAR), plasminogen activator inhibitors (PAIs), matrix metal oproteinase-3 (MMP-3), interleukin-1 beta (IL-1β) and tumor necrosis factor-α(TNF-α) in osteoarthritis synovial cel s of rats and to discuss the mechanism by TGXTC medicated serum prevents and cures osteoarthritis. METHODS:Rat models with knee osteoarthritis were established by injecting 4%papain into the knee joint cavity. Primary synoviocytes and osteoarthritis synoviocytes were cultured with col agenase digestion method. The cultured synoviocytes were divided into normal group, model group and TGXTC group. The western blot method was adopted to detect uPA, uPAR, PAI, MMP-3, IL-1βand TNF-αprotein expression of synoviocytes after acting by TGXTC medicated serum for 72 hours. RESULTS AND CONCLUSION:The expression of uPA, uPAR, MMP-3, IL-1βand TNF-αwere decreased, while PAI was increased in the TGXTC group, and there were significant differences when compared with model group. In a word, TGXTC can significantly inhibit the expression of uPA, uPAR, MMP-3, IL-1β, TNF-α, and improve PAI expression in synoviocytes, which may partly explain the mechanism of the treatment of Tougu Xiaotong Capsule on osteoarthritis.
RESUMO
With the continuous improvement of people's living standard, more and more people are in pre-diabetes state. Pre-diabetes is the key to the development of diabetes, and early intervention can reduce the incidence of diabetes, and prevent transforming pre-diabetes to diabetes in order to maintain the health status of the patient. By retrieving the Chinese Biomedical Literature Database of nearly five years on pre-diabetes intervention literature, it was found that traditional Chinese medicine interventions in pre-diabetes have a relatively new understanding. Through the traditional Chinese medicine, acupuncture, acupoint massage, and combine traditional Chinese and western medicine, medicinal food, eight brocade etc intervention therapy in patients with pre-diabetes, the occurrence and development of diabetes and its complications can be effectively prevented.
RESUMO
BACKGROUND:Bone marrow stromal stem cel s have multilineage differentiation capacity and can differentiate into transparent chondrocytes under certain conditions, which can provide new thoughts for treatment of osteoarthritis. OBJECTIVE:To investigate the effects of Tougu Xiaotong Granule containing serum on the cartilage differentiation of bone marrow stromal stem cel s. METHODS:Bone marrow stromal stem cel s from Sprague-Dawley rat limbs were cultured in vitro, and those cel s at passage 3 were used in the study. Cel s were divided into six groups:saline serum group, Tougu Xiaotong Granule water extract group, Tougu Xiaotong Granule alcohol extract group, chondroinductive group, Tougu Xiaotong Granule water extract and chondroinductive group, Tougu Xiaotong Granule alcohol extract and chondroinductive group. The Sox9, col agen Ⅱ, and col agen X mRNA and protein expression levels were tested by real-time polymerase chain reaction and western blot analysis. RESULTS AND CONCLUSION:After cel s were intervened with drug-containing serum for 14 days, the Sox9, col agen Ⅱ, and col agen X mRNA and protein expression in Tougu Xiaotong Granule water extract group, Tougu Xiaotong Granule alcohol extract group, chondroinductive group, Tougu Xiaotong Granule water extract and chondroinductive group, Tougu Xiaotong Granule alcohol extract and chondroinductive group were significantly higher than that in saline serum group (P<0.05, P<0.01). In addition, the chondroinductive group, Tougu Xiaotong Granule water extract serum and chondroinductive group, Tougu Xiaotong Granule alcohol extract and chondroinductive group showed significantly higher expression levels than Tougu Xiaotong Granule water extract serum group, Tougu Xiaotong Granule alcohol extract group (P<0.01). Sox9 expression in Tougu Xiaotong Granule water extract serum and chondroinductive group were significantly higher than that in the chondroinductive group. Experimental findings indicate that, Tougu Xiaotong Granule containing serum can accelerate bone marrow stromal stem cel s differentiate into cartilage cel s by up-regulation of Sox9 expression.
