Objective To explore if the treatments with the diclofenac diethylamine emulge import by pulsed ultrasound, massage therapy and quadriceps muscle strengthen training can promote the recovery of prorpioception in patients with knee osteoarthritis. Methods On the basis of health education, 30 elderly patients aged 60 or over with knee osteoarthritis were accepted treatments with 10 times of diclofenac diethylamine emulge import by pulsed ultrasound, 6 times of massage therapy in 2 weeks, and quadriceps muscle strengthen training once or twice a day. Results There were significant differences in the scores of Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), the maximum isometric extension strength of involved knees, the average isometric extension strength of involved knees and the reposition accuracy error mean of involved knees before and after the treatments (P<0.05). Conclusion The treatments with the diclofenac diethylamine emulge import by pulsed ultrasound, massage therapy and quadriceps muscle strengthen training can not only play a therapeutic effect and shorten the duration of treatment, but also promote the recovery of proprioception in subjects with knee osteoarthritis significantly.

ObjectiveTo observe the short-term efficacy of treatment with the diclofenac diethylamine emulge import by pulsed ultrasound, massage therapy and quadriceps muscle strengthen training to the patients with knee osteoarthritis for elderly.MethodsOn the basis of health education, 30 elderly patients with knee osteoarthritis were accepted treatments with 10 times of diclofenac diethylamine emulge import by pulsed ultrasound, 6 times of massage therapy and then they completed quadriceps muscle strengthen training once or twice a day.ResultsThe pain, walking ability, sit-to-stand ability and lower extremities muscle strength improved significantly for the patients after treatments (P<0.05 or P<0.001). ConclusionThe diclofenac diethylamine emulge import by pulsed ultrasound, massage therapy and quadriceps muscle strengthen training have a good short-term efficacy to the elderly patients with knee osteoarthritis.

Objective To study the relationship among static and dynamic position sense of lower extremity, physical function, and static and dynamic balance in patients with knee osteoarthritis. Methods 32 patients with knee osteoarthritis were tested with Lequesne Index, static and dynamic position sense of lower extremity, and fall risk of static and dynamic balance, and analyzed with Pearson correlation coefficient. Results The medium-to-high-frequency in postural sway correlated with Lequesne Index (r=0.36, P<0.05) and fall risk index of static balance (r=0.85, P<0.001), but not with the fall risk index of dynamic balance (r=0.30, P>0.05). The reposition accuracy error of the unaffected/ mild-affected lower extremity and affected/severe-affected lower extremity correlated with Lequesne Index (r=0.33~0.39, P<0.05), the fall risk index of static (r=0.38~0.45, P<0.05) and dynamic balance (r=0.65~0.70, P<0.05). Conclusion Lower extremity dysfunction post knee osteoarthritis would result in poor proprioception that maintains balance.

Objective To explore the feature of balance function and falling risk in the elderly knee osteoarthritis patients with single knee pain or double knees pain. Methods 30 elderly knee osteoarthritis patients without pain, 30 with single knee pain and 32 with double knees pain were tested with timed up and go test (TUG), postural stability (PS), limits of stability (LOS) and dynamic fall index (DFI). Results There was significant difference in the elderly between no pain and single or double knee pain (P<0.05) in TUG, but not between the single knee pain and double knees pain (P>0.05). There was no significant difference in the elderly between single knee pain and no pain (P>0.05) in PS, but was between double knees pain and the other 2 groups (P<0.05). There was significant difference between no pain and single or double knee pain (P<0.05) in LOS, but not between single knee pain and double knees pain (P>0.05). There was significant difference between no pain and single or double knee pain (P<0.05) in DFI, and between single knee pain and double knees pain (P<0.05). Conclusion The elderly osteoarthritis patients with single knee pain are in high falling risk with their dynamic balance injury, while those with double knees pain are in higher falling risk with their static and dynamic balance injury.

Objective:To investigate the expressions and significance of tyrosine kinase receptor EphA2 and its ligand ephrinA1 in human malignant gliomas and their correlation with tumor angiogenesis. Methods:The expressions of EphA2, ephrinA1, and CD105-stained microvessel density (MVD) were detected via immunohistochemical assay in 62 glioma tissues and 8 normal brain tissues. The correlation between EphA2 and ephrinA1 expression and microvessel counts in the glioma tissues were assessed. Results:Immunohistochemical staining results revealed that variable levels of EphA2 and MVD expression were significantly higher than that of the normal brain samples. Statistical difference was observed in EphA2 and MVD expressions between human gliomas and normal brain samples (P<0.01). The positive rate of EphA2 and MVD expressions was significantly higher in high-grade gliomas (WHO III-IV) than that in low-grade gliomas (WHO I-II) (P<0.01). EphrinA1 was expressed at low levels in most malignant gliomas, and the increased ephrinA1 expression was associated with lower-grade histology. MVD was significantly positively correlated with EphA2 expression (r=0.713, P<0.01) and significantly negatively correlated with ephrinA1 expression (r=-0. 772, P<0.01). EphA2 was significantly negatively correlated with ephrinA1 expression (r=-0.912, P<0.01). Conclusion:Specifically over-expressed EphA2 and its low-expressed ligand ephrinA1 in malignant gliomas may be closely correlated with the invasion and malignant degree of gliomas. Cooperation is involved in the angiogenesis and has an important function in the initiation and progression of gliomas.

Objective To explore the prognostic value of modified Glasgow prognostic score (mGPS) and risk factors in predicting overall survival (OS) in the castrate-resistant prostate cancer (CRPC) treated with docetaxel-based chemotherapy.Methods We retrospectively analyzed the data of 48 consecutive Chinese patients with CRPC received docetaxel-based chemotherapy in our institution from January 2008 to January 2012.Patients were divided into three groups according to the mGPS:0,1 and 2 score groups,and compare the OS among the three groups.Variables that were influenced the efficacy of chemotherapy were included in the univariate analysis and multivariate model.Survival analysis was performed using Kaplan-Meier curves,and the differences in overall survival rates were assessed using the Logrank test.Results The follow-up was performed until April 2014.There were 48 CRPC patients including mGPS 0 score group 30 cases,mGPS 1 score group 11 cases and mGPS 2 score 7 cases.The median OS was 22,11,9 months,respectively,P＜0.01.Univariate analysis showed that:prechemotherapy baseline total prostate-specific antigen (tPSA),Eastern Cooperative Oncology Group (ECOG) score,the number of chemotherapy cycle,visceral metastasis and PSA response were associated with poor prognosis (P＜0.05).Multivariate analysis showed that:prechemotherapy mGPS 1-2 score,baseline tPSA＞60 μg/L,the number of cycles of chemotherapy≤5,with visceral metastasis and PSA response in patients with CRPC were independent risk factors for prognosis in the CRPC treated with docetaxel-based chemotherapy.Conclusion mGPS is an independent risk factor for prognosis in the CRPC patients treated with docetaxel-based chemotherapy.

Objective To explore the relationship between the somatosensory evoked potential (SEP) diversification during operation and the short term outcome of ossification of posterior longitudinal ligament (OPLL) of cervical spine. Methods 70 OPLL inpatients from February 2008 to February 2011were included in this study. All patients received anterior cervical operation. According to the diversification of the SEP during surgery, the patients were divided into 2 groups. The preoperative and postoperative JOA scores of the OPLL patients were collected. Results There were 35 patients in the SEP no change group and 30 in SEP improved group. There was no difference in the preoperative JOA scores between them (P>0.05), but was significantly different in the postoperative JOA scores (P>0.05). Conclusion There is some relationship between the SEP diversification during operation and the short term outcome of OPLL of cervical spine.
