With the continuous improvement and innovation of modern engineering technology and biomedical technology,many efforts and process have been made on multifunctional prosthesis systems and have gained more and more attentions.The multifunctional powered prosthesis has become one of the research areas in the current muscular rehabilitation medicine and neural engineering.The bionic control of prosthesis,especially using the neural signal to control the upper prosthesis effectively,is one of the most important fields of prosthesis technology.Choosing the proper neural signals seems to be particularly important for bionic prosthetic control strategy.Currently,several different signal controls such as EMG control,EEG control,voice signal control and peripheral nerve signal control have been proposed and investigated for the bionic control of multi-function prosthesis.This paper reviews the latest efforts and progress of multifunctional upper prosthesis.

Objective: Through treatment based on differentiation of symptoms and signs and classification of defi nited patients of maternofetal blood group incompatibility, detecting anti-A or Anti-B antibody and erythrocyte immune complex chaplet rate(RICR) and erythrocyte receptor chaplet rate(RC3bR) , etc, to observe the therapeutic effect and mechanism of prescriptions mainly with Yinchenhao Decoction. Methods: Patients definited maternofetal blood group incompatibility were divided into control group and observation group according to random principle in 1:3 ratio. Then, observation group was divided into moist heat group(SRG), moist heat and defi ciency of spleen qi group (SR+PQXG) and moist heat and defi ciency of kidney qi group(SR+SQXG) according to syndrome differentiation. Corresponding prescriptions were used, every 30 doses 1 course. Before and after treatment, the anti-A or anti-B antibody and RICR, RC3bR were detected in peripheral blood. Results: In Yinchenhao Decoction group with 21 cases, the anti-A or anti anti-B antibody decreased, including 5 case (1:64) and 4 case (1:32). In group of syndrome differentiation with 63 cases, the anti-A or anti anti-B antibody decreased, including 33 case(1:64) and 20 case (1:32). Before and after treatment, RICR of control group and observation group were(19.43?5.29), (19.57?6.50)and (20.59? 7.96), (23.77?5.12), respectively. RC3bR were(11.62?4.16), (12.42?6.60)and(11.93?4.10), (13.96?6.40)respectively. There was signifi cant difference of before and after treatment in obserbation group(P0.05). Conclusion: In cutting down anti-A and anti-B antibody, and increasing RICR and RC3bR fi eld, the observation groups were better than control group.

OBJECTIVE: Increasing of adhesion between leukemia cells and endothelial cells during all-trans retinoic acid (ATRA) treatment plays an important role in retinoic acid syndrome. This work observed the effects of tripterine on this ATRA-caused increasing in adhesion. METHODS: The effects of tripterine on ATRA-induced expressions of adhesive molecules in acute promyelocytic leukemia cell line NB4 and human umbilical vascular endothelial cells (HUVEC) were detected by flow cytometry. The effects of tripterine on adhesion between ATRA-treated NB4 and HUVEC were determined by adhesive assays. RESULTS: ATRA caused remarkable elevation of intercellular adhesion molecule-1 (ICAM-1) in NB4 cells, which could be significantly reduced by tripterine (P<0.01). The expressions of E-selectin, vascular cell adhesion molecule-1 (VCAM-1) and ICAM-1 in HUVEC were elevated by conditioned medium from ATRA-induced NB4 (ATRA-NB4-CM) (P<0.01), and inhibited by tripterine with inhibition rates being 25.3%, 42.4% and 61.0% respectively. ATRA increased the adhesion between NB4 and HUVEC, which was reversed completely by tripterine. CONCLUSION: Tripterine can inhibit ATRA-caused adhesion between leukemia cells and endothelial cells, and it might be a potential agent for treating retinoic acid syndrome.

BACKGROUND:Slow growth of peripheral nerve, muscle denervation atrophy and fossilization of motor end plate fol owing sciatic nerve injury cause irreversible limb function disorders. Umbilical cord mesenchymal stem cells have been widely used in multi-disciplinary research, but studies concerning umbilical cord mesenchymal stem cells delaying denervated muscle atrophy in rats fol owing peripheral nerve injury are rarely reported.
OBJECTIVE:To observe the value of human umbilical cord mesenchymal stem cells transplantation to delay denervated muscle atrophy of rats after sciatic nerve injury.
METHODS:Umbilical cord blood was col ected from healthy parturient woman after ful-term delivery. In the experimental group, the rat’s Sunderland IV degree sciatic nerve injury model was established by 5 mm denervation, epineurial repair, and 5 mm smal gap transplantation of umbilical cord mesenchymal stem cells. In the control group, after modeling, the same volume of normal saline was injected into the smal gap. The main outcome measures included the sciatic nerve function index, the wet weight of triceps surae,sciatic nerve latency, action potential conduction velocity and amplitude,and skeletal muscle fiber cross section area maintenance rate.
RESULTS AND CONCLUSION:After 4, 8 and 12 weeks of modeling, the sciatic nerve function index values, the wet weight of triceps surae and skeletal muscle fiber cross section area maintenance rates in the experimental group were significantly higher than those in the control group (P<0.05). After 12 weeks of modeling, electromyography results showed sciatic nerve latency was significantly lower, but action potential conduction velocity and amplitude were dramatical y higher in the experimental group than the control group (P<0.05, P<0.001). Human umbilical cord mesenchymal stem cells transplantation in denervated muscle atrophy rats after sciatic nerve promotes nerve growth, delays denervated muscle atrophy, maintains the denervatied neuromusle’s morphology and function.

OBJECTIVETo observe the efficacy difference among medication, medication plus rehabilitation training and medication plus rehabilitation training plus acupuncture on injury of nervus peroneus communis.

METHODSA total of 81 patients were randomly divided into a control group, an observation 1 group and an observation 2 group; three patients dropped out and 78 patients were included into statistical analysis, 26 patients in each group. The patients in the control group were treated with oral administration of mecobalamin, 500 μg per time, 3 times a day for 60 days. Based on the treatment of control group, the patients in the observation 1 group were treated with rehabilitation training by computer-aided movable and measurable ankle-foot orthosis (CMM-AFO). Based on the treatment of observation 1 group, the patients in the observation 2 group were treated with acupuncture at Jiexi (ST 41), Fenglong (ST 40), Yanglingquan (GB 34) and Zusanli (ST 36), etc, 30 min per treatment, once a day for 60 days. After 60-day treatment, the clinical efficacy was evaluated; the muscle strengths of foot dorsal stretch and digital flexion were evaluated; the motor nerve conduction velocity (MCV) and sensory nerve conduction velocity (SCV) were recorded.

RESULTSAfter treatment, 20 patients were cured in the observation 2 group, which was significantly higher than 8 patients in the control group and 15 patients in the observation 1 group (both <0.05). The muscle strengths, SCV and MCV in the observation 2 group were significantly higher than those in the control group and the observation 1 group (all <0.05).

CONCLUSIONAcupuncture combined with CMM-AFO have significant efficacy on injury of nervus peroneus communis, and improve muscle strengths, SCV and MCV, which are superior to medication alone and medication plus rehabilitation training.

Objective To investigate the effects of low frequency stimulation (LFS) on proliferation and angiogenesis of neural stem cells (NSC) in cerebral infarction side in rats. Methods The rats with permanent middle cerebral artery occlusion (MCAO) were randomly divided into sham-operation group, control group and LFS group, each group was divided into 7 days and 14 days subgroups with 12 rats in each subgroup. LFS therapy was started 2 days after operation. The degree of nerve function defect was evaluated with Neurological Severity Score (NSS), and the 5-bromodeoxy-dine (BrdU) positive cells in the subventricular zone (SVZ) of cerebral infarction side were detected with immunofluorescence. Stromal cell-derived factor 1(SDF-1) and vascular endothelial growth factor (VEGF) in infarction side were detected with enzyme-linked immunosorbent assay (ELISA). Results The NSS score was lower in the LFS group than in the control group and the sham-operation group 14 days after surgery (P<0.01). The number of BrdU positive cells, the content of SDF-1 and VEGF in the ischemic side were more in the LFS group than in the other groups (P<0.01) after treatment. Conclusion LFS can improve the neurological function in rats with acute cerebral infarction, which may associate with activating SDF-1/CXCR4 axis.
