Objective To observe the effects of Kinesio taping on upper limb spasticity after stroke. Methods From March to Novem-ber, 2015, 39 stroke patients were divided into Kinesio taping group (Kinesio taping and rehabilitation, n=13), white taping group (white tap-ing and rehabilitation, n=13) and blank group (rehabilitation, n=13) randomly. They were evaluated with modified Ashworth Scale (MAS), Fugl-Meyer Assessment (FMA) of upper limbs and the modified Barthel Index (MBI) before treatment, four and eight weeks after treat-ment. Results There was no significant difference among the three groups in the scores of FMA and MBI (P>0.05) four weeks after treat-ment, but the score of MAS improved more in the Kinesio taping group than in the other two groups (P<0.05). The scores of MAS, FMA and MBI all improved more in the Kinesio taping group than in the other two groups (P<0.05) eight weeks after treatment. Conclusion The application of Kinesio taping can relieve upper limb spasticity, and improve motor function and activities of daily living for patients with stroke.

OBJECTIVETo explore clinical outcomes of talus neck fracture treated with mini-plate internal fixation through dual-incision approaches.

METHODSFrom August 2010 to February 2013,18 patients with closed talus neck fractures were treated (10 males and 8 females, aged from 31 to 66 years old with an average of 38.2 years old) with mini-plate internal fixation through dual-incision approaches. According to Hawkins classification, 12 cases were type II and 6 cases were type III. All cases were evaluated with X-ray and 3D CT scan preoperatively to define type and comminuted degree of fractures. Mini-plate fixation with dual-incision approaches was performed after swelling was resolved. X-ray films were taken during following up regularly. Functional evaluation was carried out according to Visual Analogue Scale (VAS), the ankle and hind-foot score of American Orthopedic Foot and Ankle Society (AOFAS). Complications were also recorded.

RESULTSSixteen patients were followed up with an average time of 22.6 months (ranged, 17 to 46 months). No wound infection, skin and flap necrosis or implant failure were found. Traumatic arthritis in subtalarjoint was found in 1 patient. Preoperative VAS (5.94±1.12) was decreased to postoperative (1.06±1.06) (t=27.13, P<0.05). The average AOFAS score was 88.7510.19 at the latest following up; and 11 cases obtained excellent results, 3 good and 2 moderate.

CONCLUSIONMini-plate fixation with dual-incision approaches for talus neck fracture especially for talus neck comminuted fracture, an effective method, could obtain stable fixation, decrease complications.

AIM Fas system plays an important role in the mechanism of immune escape and counterattack of colon cancer cells. This study was to investigate the influence of anti-tumor drugs on Fas, Fas ligand expressions on colon cancer cells. METHODS MTT method was used to get the inhibition concentration 50%(IC_ 50 ) of 5-fluorouracil (5-Fu), mitomycin (MMC), cisplatin (CP) to SW480. The concentrations of anti-tumor drugs were 0, 0.5 IC_ 50 , IC_ 50 , 2 IC_ 50 , respectively. Immmunocytochemical staining and flow cytometry analysis were used to detect the expression rates of Fas and FasL on SW480 cells before and after 5-Fu, MMC, CP treatments. In situ hybridyzation was used to observe Fas, FasL mRNA in SW480 cells before and after treatments. RESULTS IC_ 50 of 5-Fu, MMC, CP to SW480 were 11.70, 3.12, 3.40 mg?L -1 , respectively. Both immmunocytochemical staining and flow cytometry analysis found that without drug treatments SW480 expressed high FasL and low Fas, after the treatment of 5-Fu, Fas expression rates on SW480 increased but FasL remained unchanged; both Fas and FasL increased after the treatment of MMC or CP. In situ hybridization showed that after the treatment of 5-Fu and Fas mRNA on SW480 increased while FasL mRNA remained unchanged; both Fas mRNA and FasL increased after the treatment of MMC or CP. CONCLUSION Anti-tumor drugs can change the expression of Fas system on SW480 cells in different ways. MMC and CP can increase the sensitivity of colon cancer cells to apoptosis signals; at the same time, they possibly facilitate immune escape of tumor cells. However, 5-Fu does not have influence on immune escape of colon cancer cells. The target point is at the level of transcription or above it.-

Mild cognitive impairment (MCI) is a transitional stage between normal aging and dementia. The main characteristic of the patients with MCI is the impairment of episodic memory in which hippocampus plays an important role. Therefore, the detection of structural and functional changes of hippocampus will be the key to early diagnosis of MCI. This paper presents a brief overview of recent study about hippocampal magnetic resonance imaging of MIC.

Communities of bacteria wrapped in self-generated extracellular polymeric matrix and attached to a solid surface are known as biofilm. Biofilm formation and development can be divided into three stages: adhesion of cells to a surface, reproduction of the cells, and dispersion of cells. The procedure, which surface-attached biofilm disperses bacterial cells into the environment to colonize new sites, is defined as biofilm dispersal. Biofilm dispersal is an essential stage of biofilm life cycle. It plays an important role in the transmission of bacteria. For many pathogenic bacteria, biofilm dispersal can transform bacteria in biofilm into planktonic state and promote the spread of infection. The formation of biofilm may increase the resistance of bacteria to antimicrobial agent and host defence response compared with planktonic cells. In the oral cavity, oral microorganism can attach to the surface of oral tissue and prosthesis to form biofilm. Dental caries and periodontal disease are oral chronic infections diseases of the oral tissue. The occurrence of them has a close relationship with biofilm. The mechanism of dispersal is a hot topic in recent years. Some agents which promote dispersal might be a therapeutic potential against biofilm infections. The clinical implication of dispersal agents and potential application are promising. This article reviews the dispersal-inducing agents of oral biofilms.

BACKGROUND:Studies have different views on the effect of repetitive transcranial magnetic stimulation applied in stroke patients for improving motor function.
OBJECTIVE:To evaluate the effect of repetitive transcranial magnetic stimulation on rehabilitation of motor function in patients with stroke.
METHODS:We searched Cochrane Central Register of Control ed Trials, PubMed, ISI Web of science, Medline, EMBASE, China Biology Medicine disc, China National Knowledge Infrastructure, VIP Database for Chinese Technical Periodical, Wanfang Data (from database building to July 2013) for randomized control ed trials concerning repetitive transcranial magnetic stimulation on improving motor function in patients with stroke. The included studies were evaluated according to the method recommended by the Cochrane Col aboration. Meta analysis was performed in qualified literatures. The extracted data were analyzed by RevMan 5.1 software and GRADEprofiler 3.6 software.
RESULTS AND CONCLUSION:A total of 23 trials were included (intervention group n=400, control group n=301). Quantitative analysis was conducted in seven studies, and descriptive study was performed in the remaining studies. Meta-analyses analyzed Fugl Meyer Motor Scale and Barthel index. Results showed that Fugl Meyer Motor Scale [SMD=0.48, 95%CI(0.10, 0.86)] and Barthel index [SMD=1.38, 95%CI (0.68, 2.09)] were significantly higher in the intervention group than that in the control group. In accordance with The Grading of Recommendations Assessment, Development and Evaluation, outcome indexes were evaluated, and the two indexes were graded low quality. The current evidence shows that repetitive transcranial magnetic stimulation appears to enhance motor function and activities of daily living of the patients with stroke. Considering the limitations of the included studies, more multi-central randomized control ed trials with large sample sizes and high qualities are required in future to verify the therapeutic efficacy of repetitive transcranial magnetic stimulation on motor function of stroke patients.
