OBJECTIVE: This study aimed to clarify the morphology of the Martin-Gruber anastomosis (MGA) in Chinese. METHODS: One hundred and five Chinese upper limbs (36 males and 20 femalese) were dissected to find the connections between medial nerve and ulnar nerve. The MGA was classified as previously described by Lee. RESULTS: MGA was found in 24 cases (22.9%), in 11 of the 36 male and 5 of the 20 female. There was no obvious difference in the frequency of MGA in both upper limbs. Most MGA ulnar position was located at the medial and distal segment of the forearm. CONCLUSION MGA anatomy could play important role in forensic diagnosis of ulnar nerve injury in Chinese population.

OBJECTIVETo locate motor functional area of patients who undergone modified anatomical hemispherectomy in order to analysis the plasticity of upper limbs motor.

METHODSThe patients who undergone modified anatomical hemispherectomy were performed BOLD sequences, to locate functional cortical areas in their residual brain.

RESULTS6 patients have performed examination of BOLD sequences by 3.0-T MRI.5 of them obtained contralateral upper limb motor areas in their residual brain, and 3 of them obtained ipsilateral and contralateral upper limb motor area map in cortex. The ipsilateral upper limb motor areas in the M1, SMA and posterior parietal cortex.

CONCLUSIONSThe patients who undergone modified anatomical hemispherectomy is an excellent model to investigate mechanism of plasticity in the developing brain. Functional magnetic resonance (fMRI) provided fine spatial detail of brain responses, would describe the motor functional area of cortical maps. These patients exist ipsilateral motor areas in their residual mono hemisphere. The study indicated there maybe have somewhat extent of correlation between the surgical procedure and the outcome of neuroplasticity.

OBJECTIVETo search for the best program for treatment of peripheral nerve incomplete injury.

METHODSNinety cases were randomly divided into a treatment group, a control group I and a control group II, 30 cases in each group. The treatment group were treated with electroacupuncture at Jianyu (LI 15), Hegu (LI 4), Quchi (LI 11), etc. plus functional training, and the control group I with electroacupuncture and the control group H with functional training. After treatment for 3 months, basic function, practical function, EMG, nerve conduction velocity were compared among the 3 groups.

RESULTSThe good rate of basic function of 50.0%, the curemarkedly effective rate of practical function of 50.0% and the total effective rate of neurophysiology of 64.3% in the treatment group were better than 20.7%, 17.2%, 41.4% in the control group I (P < 0.05) and 23.3%, 20.0% and 36.O7% in the control group II (P 0.05).

CONCLUSIONElectroacupuncture combined with functional training can accelerate nervous repair, promote functional recovery of the denervated muscles, so as to shorten the restoring time of nerve-muscle and increase life quality of the patient.

PURPOSE: We compared three methods of ultrasound-guided axillary brachial plexus block, which were single, and double perivascular (PV) infiltration techniques, and a perineural (PN) injection technique. MATERIALS AND METHODS: 78 patients of American Society of Anesthesiologists physical status I-II undergoing surgery of the forearm, wrist, or hand were randomly allocated to three groups. 2% lidocaine with epinephrine 5 microg/mL was used. The PN group (n=26) received injections at the median, ulnar, and radial nerve with 8 mL for each nerve. The PV1 group (n=26) received a single injection of 24 mL at 12-o'clock position of the axillary artery. The PV2 group (n=26) received two injections of 12 mL each at 12-o'clock and 6-o'clock position. For all groups, musculocutaneous nerve was blocked separately. RESULTS: The PN group (391.2+/-171.6 sec) had the longest anesthetic procedure duration than PV1 (192.8+/-59.0 sec) and PV2 (211.4+/-58.6 sec). There were no differences in onset time. The average induction time was longer in PN group (673.4+/-149.6 sec) than PV1 (557.6+/-194.9 sec) and PV2 (561.5+/-129.8 sec). There were no differences in the success rate (89.7% vs. 86.2% vs. 89.7%). CONCLUSION: The PV injection technique consisting of a single injection in 12-o'clock position above the axillary artery in addition to a musculocutaneous nerve block is equally effective and less time consuming than the PN technique. Therefore, the PV technique is an alternative method that may be used in busy clinics or for difficult cases.
