BACKGROUND:Previous studies have confirmed that healing of in vivo tendon is the outcome of interaction between endogenous healing and exogenous healing. Exogenous healing is a main reason for tendon adhesion, and affects the recovery of tendon function.OBJECTIVE: To explore application of tissue engineering technique and its materials in prevention and treatment of tendon adhesion induced by movement injury.METHODS: Using the key words of "movement injury, biomaterial, tissue engineering, tendon adhesion", we retrieved randomized animal controlled studies and clinical application literatures addressing tendon biomechanics function, adsorbable biomaterial polyglycolic acid, tendon cells-constructed tissue engineered tendon in vitro, biomembrane, chitosan, adsorbable antistick membrane, sodium hyaluronate, bioprotein gel and so on in prevention of tendon adhesion in Chinese Journal Full-text Database published from January 1990 to December 2000. By aggregate analysis of literature data, follow-up and function evaluation, this article summarized clinical application of tissue engineered techniques and materials in prevention of tendon adhesion.RESULTS AND CONCLUSION: A total of 61 literatures were primarily obtained. Following reading titles and abstracts, 31 literatures of irrelevant objectives and contents, and 9 literatures of repetitive contents were excluded. Totally 21 literatures were included for analysis. Tendon adhesion refers to hyperplasia and invasion of surrounding tissues during repair of tendon damage. With the deep understanding of tendon repair healing, application of tissue engineering to preventing tendon adhesion became more and more. Tendon healing is an interaction between endogenous healing and exogenous healing, and mainly endogenous healing, which was simultaneously associated with tendon sheath, vincula tendinum and synovial fluid. Tendon adhesion is mainly induced by excessive action of exogenous healing and damage to surrounding tissues. Tissue engineering is a novel technique. Novel biomaterials are widely used in tissue engineering performance to solve problems such as tendon injury andchondronecrosis. Presently, it Is important to reconstruct tissues, which can reach clinical outcomes of preventing adhesion.

Objective To observe the effects of electroacupuncture on expression of caspase-3 in the is- chemic penumbra in the early stage of cerebral ischemia in rats. Methods 100 Wistar rats were randomly divid- ed into a sham-operated group, a model group and an electroacupuncture group. The middle cerebral artery was ex- perimentally occluded in the rats in the model and electroacupuncture groups, while a sham operation without cere- bral artery occlusion was carried out on the rats in the sham-operated group. Immunocytochemistry was employed to detect the expression of caspase-3 in the ischemic penumbra at 24 h, 48 h and 72 h after cerebral ischemia. Re- suits There was almost no positive expression of caspase-3 in the sham-operated rats. Numerous caspase 3-posi- tive cells were found in the ischemic penumbra in the model and electroacupuncture groups. The peak of expression was reached 24 hours after cerebral ischemia. The number of caspase 3-positive cells was significantly greater in the model group than in the electroacupuncture group at 24 h and 48 h. Conclusion The increase of caspase 3-posi- tive cells in the ischemic penumbra is time-dependent. Electroacupuncture can significantly decrease the expression of caspase-3.

Objective To study the effects of uhrashortwave and low frequency pulsed electromagnetic fields on the expression of vascular endothelial growth factor(VEGF) in fracture healing. Methods Fifty-six New Zeal-and rabbits with artificial fractures were randomly divided into 4 groups:a control group,an ultrashortwave group,a low frequency pulsed electromagnetic field group and an ultrashortwave combined with low frequency pulsed electro-magnetic field group(combined group),with 14 in each group.Radiographic evaluation of callus formation and frac-ture healing,pathohistological examination and detection of VEGF expression through immunohistochemical staining were performed at the 1 st,2nd,4th and 6th week after the operation. Results Radiographic examination showed that there was significantly greater callus formation in the combined group than in the other groups throughout the healing process. Pathohistological examination also revealed significantly more cartilage islets and callus formation in the combined group.At the 1 st,2nd and 4th week after the operation,VEGF positive indexes in the combined group were significantly higher than in the other groups. Conclusion Uhrashortwave combined with low frequency pulsed electromagnetic field exposure can up-regulate the expression of VEGF and thus can accelerate fracture healing.

Objective: To investigate the difference in behavioral characteristics among different phenotypes of attention deficit hyperactivity disorder (ADHD) using amplitude of low-frequency fluctuation (ALFF), so as to provide insights into clinical differentiation of behavioral characteristics among different phenotypes of ADHD. Methods: The children with ADHD admitted to The Affiliated Hospital of Hangzhou Normal University were enrolled and classified into the inattentive type (ADHD-I), hyperactive/impulsive type (ADHD-HI) and combined type (ADHD-C). The reaction time (RT) was measured using integrated visual and auditory continuous performance test, and the mean (RT-mean) and standard deviation of RT (RT-SD) were estimated. In addition, the ALFF was calculated at 0.010 to 0.027, 0.027 to 0.073, 0.073 to 0.167 Hz, and the difference of ALFF was compared among children with different types of ADHD. Results: A total of 107 children with ADHD were enrolled, including 95 boys and 12 girls, with a mean age of (8.89±1.93) years. There were 69 children with ADHD-I, 8 children with ADHD-HI and 30 children with ADHD-C. The RT-SD was significantly higher among children with ADHD-C than among children with ADHD-I [(126.003±51.619) ms vs. (97.720±45.302) ms; P=0.007]; however, there was no significant difference in RT-mean among children with various ADHD phenotypes (F=1.386, P=0.255). There was an interaction between frequency and ADHD phenotypes (F=2.754, P=0.032), and the ALFF was significantly higher among children with ADHD-C than among children with ADHD-I at 0.010 to 0.027 [(5 590.567±231.595) ms vs. (4 694.001±154.397) ms; P=0.002] and 0.073 to 0.167 Hz [(4 312.609±174.709) ms vs. (3 690.805±116.473) ms; P=0.005]. Conclusions The ALFF varies in ADHD phenotypes, and there is a frequency-specific difference.

Objective To investigate the effects of citicoline combined with rehabilitative training on motor function after focal cerebral ischemia. Methods One hundred and twenty male adult Sprague-Dawley rats ( 3 months old) were subjected to left middle cerebral artery occlusion (MCAO) by suturing. Ninety-six of them were randomly divided into four groups of 24: a control group, a drug group, a rehabilitative training group, and a drug combined with rehabilitative training group. The rats in the control group did not receive any treatment. Three days after reperfusion, those in the drug group received 500 mg/kg of citicoline daily; those in the rehabilitative training group received motor training including balancing, grasping, rotating and walking exercises; those in the combined group received both citicoline and the motor training program. Behavioral tests were administered at the 7th, 14th and 21st days after MCAO. At the same time points, immunohistochemistry was used to detect calcium-binding protein S100 and β-tubulin expression in the peri-ischemia region of the cortex. Results ①As compared with the control group, the drug group at the 7th, 14th and 21st day after MCAO and the other two groups at the 7th day after MCAO showed no significant difference in average behavior scores. But at the 14th and 21st day the rehabilitative training group as well as the drug combined with rehabilitative training group had average behavior scores significantly superior to those of the control group, especially in the drug combined with rehabilitative training group. ②As compared with the control group, the expression of S100 and β-tubulin in the drug and rehabilitative training groups at the 7th day after MCAO showed no significant difference. In the drug combined with rehabilitative training group the average score was significantly higher than in the other groups at the 7th day after MCAO. All the other groups had average scores significantly higher than that of the controls at the 14th and 21st day after MCAO, especially the drug combined with rehabilitative training group. Conclusions Citicoline combined with rehabilitative training can significantly improve motor function recovery in rats. The effect of the combined modalities was more obvious, and the functional enhancement might be partially attributable to the up-regulation of S100 and β-tubulin in the cortex.
