ObjectiveTo compare the clinical effect and security of Reparil Gel on osteoarthritis of the knee.Methods60 patients were randomly divided into Reparil Gel group and Fenbid group, who applied Reparil Gel or take Fenbid orally respectively. Western Ontario and McMaster University Osteoarthritis Index (WOMAC) was used to assess patients' pain, joint stiffness and disability of knee on 0 week, 2 week, 6 week after treatment. The side effect was observed.ResultsBoth group showed good clinic effect on 2 weeks (P<0.05)and 6 weeks (P<0.001)after treatment. Significant difference between two group was found 2 weeks after treatment, but there was no difference 6 weeks after. There was no side effect had been observed in Reparil Gel group, while stomachache, nausea or anorexia had been found in 4 case of Fenbid group 2 weeks after, and 8 case of Fenbid group 6 weeks after.ConclusionReparil Gel are same effective as Fenbid, but less side effect happened.

Objective To improve clinicians' understanding of tuberculosis as the adverse event of the tumor necrosis factor alpha (TNF-α) antagonists therapy. Methods Two rheumatoid arthritis (RA) patients were reported to develop lymphoid tuberculosis and pulmonary tuberculoma after TNF-α antagonists therapy. The relevant literature were reviewed. Results The first ease was a 62 year-old female RA patient. Her skin PPD reaction was negative and chest X-ray was normal before the therapy. Following 4 doses of infliximab injection (each dose of 3 mg/kg) which were completed within 3 months, the patient developed fight supraclavicular lymphoids tuberculosis in the 5th month after the last treatment. The patient completely recovered after lymphoids excision and antituberculosis therapy with 4 anti-tuberculosis medications combination. The second case was a 44 year-old female RA patient. She did not take the skin PPD test and chest X-ray before the therapy. The patient developed fever and chest distress after etanercept therapy (25 mg hypodermic twice per week ) for 1.5 months. The chest X-ray showed a shadow in the median lobe of the right lung, which had gradually developed to a pulmonary tuberculoma. The patient's physical condition improved after the tubereuloma resection. It has been reported in recent years that ① TNF-α antagonists therapy could increase the incidence of tuberculosis, ② the incidence at which infliximab associated tuberculosis was higher than etanercept, ③ the majority of the patient having tuberculosis were old people, and ④ the incidence of extrapulmonary tuberculosis and the disseminated tuberculosis were higher than regular tuberculosis. Conclusion TNF-α antagonists may decrease the host defense ability against mycobacterium tuberculosis and increase the incidence of tuberculosis. The pre-treatment tuberculosis screening, as well as tuberculosis monitoring during and after treatment is mandatory.

Objective: To optimize the formula and preparation process of docetaxel-loaded pluronic P123 micelles. Methods:Docetaxel-loaded pluronic P123 micelles were prepared by a thin-film hydration method and optimized by central composite design and response surface methodology. The influencing factors including the quantity of docetaxel, volume of organic phase, volume of hydra-tion and temperature of hydration were investigated with the entrapment efficiency as the index. The morphology of micelles was ob-served under a transmission electron microscope. The particle diameter and zeta potential were determined. The in vitro release property was measured by a dialysis method. Results:The relationship between the influencing factors and the evaluation parameter was fitted by multi-linear equation, quadratic polynomial equation and cubic polynomial equation, respectively. The results showed that the cubic polynomial equation was superior to the others according to the correlation coefficient. Docetaxel-loaded pluronic P123 micelles were spherical with the mean diameter, zeta potential, polydispersity index, encapsulation efficiency and drug loading of 108. 3 nm,-3. 99 mV, 0. 265, (97. 91 ± 0. 28)% and (3. 72 ± 0. 12)%, respectively. The cumulative release in vitro reached 95. 03% in 120 h, and docetaxel-loaded pluronic P123 micelles had notable sustained-release property. Conclusion: The technical process for do-cetaxel-loaded pluronic P123 micelles is simple and usable, and docetaxel-loaded pluronic P123 micelles show high encapsulation effi-ciency and notable sustained-release property.

BACKGROUND:Three-dimensional (3D) motion analysis system combined with electromyograph cannot only objectively analyze movement function of the upper limb, but also exert an important role in exploring the exercise-related factors and the underlying mechanism.
OBJECTIVE:To explore the influence of movement velocity and target location on kinematics and muscle activity in upper limb reaching.
METHODS:Twelve healthy young adults reached for three different location targets (frontal, ipsilateral and contralateral) at self-selected and fast speeds to with the dominant right hand, respectively. Kinematic parameters and muscle activity were recorded by Vicon 3D motion analysis system and Noraxon wireless electromyograph, synchronously.
RESULTS AND CONCLUSION:Reach path ratio became smal er when moving faster (P<0.001), while mean velocity, peak velocity and the time percentage of peak velocity increased (P<0.001). Posterior deltoid, biceps brachi and triceps brachi activation was higher during fast speed movement (P<0.001). Muscle activation of anterior deltoid was lower in ipsitralateral reaching than contralateral (P=0.001) and frontal reaching (P<0.001), and posterior deltoid was higher than contralateral reaching (P=0.019). Biceps brachi (P=0.039) and triceps brachi (P<0.001) activation was also higher in ipsitralateral reaching than frontal reaching. These results suggest that moving fast can contribute to more muscle activation, high velocity, smooth trajectory and increased movement quality. Posterior deltoid, elbow extension and flexion muscle activation are high in ipsitralateral reaching, while high anterior deltoid activation in contralateral reaching;therefore, target location result in muscle synergies.

BACKGROUND:The interaction of neural network and motor function in post-stroke brain tissue remains unclear.
OBJECTIVE:To observe neural network impairment fol owing subacute stroke by using diffusion tensor imaging, and to investigate the relationship with neurological defects and motor dysfunction.
METHODS:A total of 19 patients after subactue stroke and 20 healthy adults were examined with diffusion tensor imaging. The fol owing parameters were compared:fractional anisotropy, apparent diffusion coefficient, asymmetry indices of fractional anisotropy and apparent diffusion coefficient. The neurological defect and motor function were evaluated with the corresponding scales. The 10-meter walking speed was measured. The correlation of diffusion tensor imaging parameters with the scale scores and 10-meter walking speed was analyzed.
RESULTS AND CONCLUSION:The stroke group exhibited reduced fractional anisotropy value asymmetry and fractional anisotropy value in bilateral posterior limbs of the internal capsule. Apparent diffusion coefficient value asymmetry and apparent diffusion coefficient value in the posterior limb of the internal capsule were lower than control unaffected side (P<0.05). Apparent diffusion coefficient value and apparent diffusion coefficient value asymmetry in posterior limb of the internal capsule showed a strong negative correlation with Fugl-Meyer assessment scores of the lower extremities (P<0.05). Diffusion tensor imaging parameters is closely linked with motor dysfunction of the lower extremities in subacute stroke patients. Local stroke lesion-caused neurological defect is the leading cause of motor dysfunction of the lower extremities.

Objective To compare the effect of intra-articular injection of recombinant human tumor necrosis factor-Fc (rhTNFR:Fc) in the treatment of knee arthritis in spondyloarthritis (SPA) with that in rheumatoid arthritis (RA).Methods The subjects included in this study were SpA and RA patients with knee arthritis without deformity,moderate or severe bone erosion and obvious joint space narrowing in radiography,who had taken at least 6-week therapy with routine dosage of disease modifying anti-rheumatic drugs (DMARDs) before the study.All subjects received one dose of 25 mg rhTNFR:Fc injected to the target knee joints after synovial fluid being drawn away before injection.They were followed up for four weeks after injection.The primary end-point was the 4-week change in the moditied hospital for special surgery (HSS) knee score for the target knee.The secondary end-point were the 4-week change in patients assessment of the knee,and investigators assessment of knee,pain VAS of the knee joint when walking or standing,the range of knee inflexion,circumference of the knee cross section,synovium thickness detected by ultrasound in the part of the thickest synovium in the suprapatellar bursa.Paired t test,independed t test and Wilcoxon test were used for statistical analysis.Results Twenty-seven SpA patients and fifteen RA patients were included in the trial.The modified HSS knee score for the SpA group was 66±14 at baseline,86±11 (P＜0.05) at follow-up,and for the RA group,the score was 64±13 at baseline,80±9 (P＜0.05) at follow-up.24.2％ (16.5％-41.9％) improve-ment on the modified HSS knee score was achieved in the SpA group,while 22.2％ (15.3％-37.7％) improvement on the modified HSS knee score was achieved in the RA group (P＞0.05).31.8％ (9.3％-57.3％) improvement on the synovium thickness was achieved in the SpA group,while 1.5％ (-19.3％-25.5％) improvement on the synovium thickness was achieved in the RA group (P＜0.05).Adverse events were observed in six patients in SpA group and two patients in RA group.No serious adverse events had been observed.Conclusion Single intra-articular rhTNFR:Fc injection is an effective and safe therapeutic option for knee arthritis in both SpA and RA patients.This treatment may relieve knee synovitis in SpA patients more effectively than in RA patients.

Objective To seek more direct evidence of the role of the posterior parietal cortex (PPC) in controlling visuospatial attention.Methods Forty healthy subjects took the Attention Network Test following continuous theta burst stimulation (cTBS) applied over the left or right PPC or sham stimulation.The Attention Network Test measures the alerting,orienting and executive control components of visual attention separately.Results Subjects responded to spatial cues significantly slower after cTBS.Alerting and orienting showed deficits after cTBS over the right PPC.cTBS over the left PPC resulted in significant improvements in alerting,but not in the orienting.Furthermore,there were significant differences in the alerting and orienting indices between cTBS over the left and right PPC,but not in the executive control index.Conclusions The results suggest that the right PPC is associated with spatial orienting and the alerting function.The findings supported the theory of inter-hemispheric competition for visuospatial attention.Visuospatial attention bias might be selectively modulated through cTBS.

[ ABSTRACT] AIM:To investigate the effect of microRNA-375 ( miR-375) on the viability, cell cycle and apop-tosis of HCT116 cells.METHODS: The expression of miR-375 in different colorectal cancer cell lines was detected by real-time PCR.The miR-375 mimics was transfected into HCT116 cells by LipofectamineTM 2000.The mRNA expression of miR-375 and AEG-1 was detected by real-time PCR.The HCT116 cell viability was detected by MTT assay.The changes of apoptosis and cell cycle distribution were analyzed by flow cytometry.RESULTS:Real-time PCR showed that miR-375 expression was the lowest in HCT116 among 4 colorectal cancer cell lines.The expression level of miR-375 significantly in-creased in miR-375 mimics group compared with that in the negative control group.The high expression level of miR-375 significantly inhibited the mRNA expression of AEG-1.After transfection with miR-375 mimics, the cell viability was in-hibited, the apoptotic rate was increased, the proportion of G1-stage cells was increased, and the proportion of S-stage cells was decreased.CONCLUSION:miR-375 inhibits the viability, mediates the cell cycle arrest and promotes the apoptosis of colon cancer HCT116 cells.miR-375 may act as a tumor suppressor in colorectal cancer by inhibiting AEG-1.
