Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a common disease in males, which is characterized by persistent discomfort or pain in the pelvic region. As currently used drug therapies fail to produce satisfactory results, it is an urgent task to find new and effective methods for the treatment of CP/CPPS. In recent years, many reports are seen on the extracorporeal shock wave therapy (ESWT) for CP/CPPS. ESWT can significantly improve the symptoms of pelvic pain and urination disorders in CPPS patients, and its therapeutic effect is attributed to the improvement of angiogenesis and block of pain nerves.

Background and purpose:P38 mitogen-activated protein kinase (P38MAPK) signal transduction pathway is involved in occurrence, development and transfer process in a wide variety of tumors. Urokinase-type plasminogen activator (uPA) plays an important role in tumor invasion and metastasis. This study aimed to explore the clinical signiifcance of the P38MAPK signaling pathway and the expression of uPA in ovarian cancer.Methods:The expressions of uPA, P38MAPK, ERK and AKT were detected in 49 cases of cervical adenocarcinoma by immunohistochemistry. The expressions of uPA and P38MAPK were detected by Western blot in ovarian cancer cell lines HO8910, HO-8910PM, SKOV3 and CAOV3. The changes of uPA and P38MAPK were detected by SB203580, a speciifc inhibitor of P38MAPK signal transduction pathway.Results:The result of immunohistochemical method showed that positive expression rates for uPA, P38MAPK, ERK and AKT were 61.22%, 57.14%, 53.06% and 55.10%, respectively. The expression of the uPA was positively correlated with the P38MAPK (r=0.865,P=0.001), and related with clinicopathologic stage, differentiated degree, lymph node metastasis, but not related with age and histologic type (P>0.05). The expressions of AKT and ERK were related with the lymph node metastasis and greater omentum metastasis(P<0.05), but not related with age and histologic type (P>0.05). The expression of uPA in HO-8910PM was higher than that in ovarian cancer cell lines HO8910, SKOV3 and CAOV3, and the expression of uPA reduced when the P38MAPK signal transduction pathway was cut off by the SB203580. The expressions of P38MAPK and uPA were negatively correlated with the prognosis of ovarian cancer (Log-rank=3.897 and 11.044,P=0.048 and 0.001). Conclusion:The P38MAPK signal transduction pathway was activated in ovarian cancer. The activated P38MAPK signal transduction pathway can raise the expression of uPA, which may contribute to the development of ovarian cancer. The result indicates that the P38MAPK signal transduction pathway and uPA might play an important role in the invasion and metastasis of ovarian cancer. P38MAPK and uPA might be useful markers for evaluating prognosis of ovarian cancer.

BACKGROUND: Anterior and dorsal root nerve tracts should be separated to small tracts in high selective dorsal rhizotomy, because detailed tract separation will benefit electrostimulation, thereby helping correctly cutting the lower-threshold Ia nerve fibers that cause convulsion, and meanwhile sensory nerve fibers in dorsal nerve root can be reserved as many as possible.OBJECTIVE: To meet the needs of limited and high selective spinal dorsal rhizotomy, anterior and dorsal root of spinal nerve were microanatomized to be certain of the separation standard and the number of small nerve tracts, so as to provide reliable basis and novel operative standard for clinical operation.DESIGN: Single sample experiment with adult corpses as subjects.SETTING: Orthopedic Department of the First Affiliated Hospital and Department of Anatomy, Jinzhou Medical College.PARTICIPANTS: This study was carried out at the Anatomical Laboratory of Jinzhou Medical College in December 1999. Fifteen adult corpses, 11 males and 4 males, were donated, and the donators signed informed consent when alive.tained from the 15 adult spinal cords (30 sides) and subjected to morphoanterior and dorsal roots of L5 spinal cord were obtained from a fresh corpse for immunohistochemical staining. The starting part, middle part and the exterior of intervertebral foremen was cut into slices, and the total number of nerve fibers, the number of Ia nerve fibers responsible for convulsion, and their percentage in the total fibers were counted. Meanwhile the distribution and the number of Ia nerve fibers in the three parts were compared.ber of nerve fibers per 100 μm2, the percentage of Ia nerve fibers in the total nerve fibers at the starting part, middle part and exterior of intervertebral foremen of spinal nerve dorsal root.root filaments. Microsurgical observation proved that dorsal root could be divided into 10-18 small tracts and anterior root 6-11 tracts; the diameter number of nerve fibers in the three parts of spinal nerve dorsal root was (3 243±143) fibers per 100 μm2, including (1 702±85) Ia nerve fibers that constituted about 52.5% of the total nerve fibers. Ia nerve fibers were found to be evenly distributed in dorsal root and no gathering could be observed.CONCLUSION: The tracts in anterior and dorsal roots of spinal cord should be separated as minutely as possible during improved dorsal rhizotomy, which is beneficial for cutting off Ia nerve fibers correctly. Generally,the anterior root consists of 6-11 small tracts and dorsal roots of 10-18small tracts, and nerve tracts should not be cut off over 1/2 of total dorsal nerve fibers.
