Objective To investigate the impact of motor imaginary therapy on the recovery of upper limb function in acute cerebral infarction patients with bemiplegia. Methods Fifty cerebral infarction patients with hemiplegia were randomly divided into a control group (drug therapy + early exercise therapy) and a motor imaginary therapy group (drug therapy + early exercise therapy + motor imaginary therapy) using single-blind method (n = 25 in each group). Ipsilateral upper extremity function was assessed by the Fugl-Meyer assessment (FMA) before the treatment and at day 40. The active range of motion (AROM) of the ipsilateral wrist was measured by a conimeter. Eating, washing, dressing, and putting on and off clothes were assessed by the Functional Independence Measure (FIM) scale. Results The scores of FMA, AROM and FIM were increased more significantly than those before the treatment in both groups (P <0.05). All the scores in the motor imaginary therapy group after the treatment were superior to those in the control group (P <0. 05) (FMA 28.33 ± 8.63 versus 15.93 ± 5.39;AROM 19.55 ± 8.30 versus11.97 ± 6.59; FIM 16.83 ± 5.43 versus 12.51 ± 3.36).Conclusions Conventional motor rehabilitation training + motor imaginary therapy during the acute phase may promote the motor function reco,,ery in cerebral infarction patients with hemiplegia.

Objective To determine and compare the levels of serum matrix metalloproteinase (MMP)-2 and MMP-9 in acute stage of cerebral infarction and the relationship and prognosis between them and the classification of TOAST. Methods The levels of MMP-2 and MMP-9 were detected by ELISA in 60 cerebral infarction patients(CI group)while 30 healthy donors were served as control group (NC group).Results The level of MMP-2 in CI group was significantly lower than that in NC group (P＜0.01) and the level of MMP-9 was significantly higher than that in NC group (P＜0.01).Compared with lacunar infarction (LI) group,the level of MMP-9 was significantly higher in cardiogenic cerebral embolism group(CCE group) and large artery arteriosclerosis cerebral infarction group (LAA group);The serum level of MMP-9 was related to NIHSS.The serum level of MMP-9 in good prognosis patients was significantly lower than that in poor prognosis patients (P＜0.01).Conclusions The serum level of MMP-9 is increased after cerebral infarction.The serum level of MMP-9 in the CCE group and LAA group is significantly higher than that in LI group.The level of MMP-9 is a reliable parameter in evaluating the disabilities in cerebral infarction.The level of serum MMP-9 within 24 hours of onset can predict the prognosis of cerebral infarction independently.

Objective To evaluate the MRI and CT representations and their valuation of intraeranial dermoid cyst. Methods 23 cases who suffered from intracranial dermoid cyst confirmed by pathology were included retrospectively. The MRI and CT representations, and the pathological and clinical characteristics were analyzed.All the cases were performed with MRI, and 20 cases were performed with CT at the same time. Results 22 cases showed inhomogeneous high signal intensity in T1WI and T2WI, 1 cases showed iso-high signal intensity in T1WI and low signal intensity in T2WI. 8 cases showed plaque-like inhomogeneous high signal intensity in DWI. 19 cases showed homogeneous low density in CT scans with standard window width and level ,amt showed inhomogeneous low density with large window width and low window level. One case showed high density in CT scans with standard window width and level. Fat drop in subrachnoid space and bilateral cerebral ventricle and interstitial brain edema were found in 8 cases with MRI and CT. Conclusion Intracranial dermoid cyst always have typical MRI and CT representations. Distinctive representations could be found when the rupture of dermoid cyst exist, and correct diagnosis could be made before operation. MRI is better than CT in the diagnosis of dermoid cyst.

BACKGROUND:Research on ethyl pyruvate detection methods is reported rarely, and moreover, literature about reversed-phase high-performance liquid chromatography (RP-HPLC) for detection of ethyl pyruvate is less.
OBJECTIVE:To establish an RP-HPLC method for determination of ethyl pyruvate in ethyl pyruvate-chitosan nanoparticles.
METHODS: The chromatographic analysis was performed on a ZORBAX Eclipse XDB-C18 column (4.6 mm× 150 mm, 5μm) at 25℃, with the mixture of acetonitrile and water (40:60, V/V) as the mobile phase at the flow rate of 1 mL/min. The determination wavelength wasset at 210 nm and the injection volume was 20 μL.
RESULTS AND CONCLUSION: The peak of ethyl pyruvate and the peaks of auxiliary materials and solvent were separated wel. The linear rang of ethyl pyruvate was 1-100 mg/L (r=0.999 6). The relative standard deviation of both the intra-and inter-day precision was less than 3% for low-, moderate-, and high-concentration ethyl pyruvate. The relative standard deviation of reproducibility test and stability test was 1.25% and 1.3%, respectively. Sample average recovery rates were (91.5±1.0)%, (3.5±0.2)%, (94.4±0.4)%, respectively. Encapsulation efficiency of samples were (87.2±0.22)%, (90.5±0.15)%, (91.1±0.17)%, respectively. The relative standard deviation of different sample content were 0.9%, 0.5%, 0.3%, respectively. The RP-HPLC method for determination of ethyl pyruvate is sensitive, accurate and highly specific with wide linear range and high sample average recovery.

BACKGROUND:There are more literature reports about the floating shoulder injury in recent years, but there stil have obvious controversies about the treatment of the floating shoulder injury. Whether choose the conservative treatment or operative treatment is an important issue in face of every clinician. OBJECTIVE:To review the clinical features and present treatment situation of the floating shoulder injury. METHODS: A computer-based online search was performed in the PubMed and the China National Knowledge Infrastructure database for the clinical research papers on the treatment methods of the floating shoulder injury from January 1975 to August 2015. The key words were floating shoulder injury, diagnose, treatment method. The articles published earlier and repetitive researches were excluded. Finaly, 33 articles were included for further analysis. RESULTS AND CONCLUSION:(1) Floating shoulder injury is a kind of severe shoulder injury which is caused by high energy and violence. It is often complicated with severe systemic injury, which should be paid more attention in clinic. (2) The treatment of floating shoulder injury has been controversial, and there is no standard treatment guideline. Conservative treatment and operative treatment can get good outcomes. There are less reports about conservative treatment of the floating shoulder injury in recent years. The outcome of operative treatment may better than conservative treatment. (3) Conservative or simple clavicle fixation can be used for fractures without displacement or with smal displacement. Obviously displaced fractures can be treated with simple clavicle fixation or double fixation of clavicle and scapula, which may have good repair effects.
