Based on the recording of the Governor Vessel in Taisu (Commentary on Huang di's Internal Classic), deeply analyze and probe cognition and feature of the Governor Vessel in Taisu, and compare with other related literatures in Huangdi's Internal Classic and Classic on 81 Medical Problems, discovering that cognition of the Governor Vessel in Taisu is more early than the theory of the Governor Vessel handed down from ancient times, infer that the Governor Vessel recorded in Taisu possibly is early model of the theory of the Governor Vessel handed down from ancient times. Further studies discover that cognition of the Governor Vessel in Taisu is related with clinical practice of "spinal cord method", which possibly is clinical basis of origination of the Governor Vessel.

The relationship of affected regions, cause of disease, pathogenesis of flaccidity with physiological functions of the Governor Vessel is expounded, indicating that "skin, muscle, tendon, vessel and joint" are basic structures of performing motor function of the organism, which depend on nourishing of qi, blood, body fluid, essence and marrow; "insufficiency of essence and marrow" and "deficiency of qi and blood" are keys of pathogenensis of flaccidity; "deficiency or obstruction of the Governor Vessel" and "yang of the Governor Vessel unable to function" are the basis of channels and collaterals for flaccidity attack. Clinically, regulation of the Governor Vessel can promote repair of morphosis and functions of the Governor Vessel (brain and spinal cord), and rebuilding of the regulative system of the brain-the Governor Vessel (spinal cord)-viscera-channels, qi and blood functional activities, so as to restore the normal distribution and transduction of qi, blood, body liquid, essence and marrow to nourish skin, muscle, tendon, vessel and joint.

OBJECTIVESTo observe the protective effect of retrograde venous perfusion of cryogenic liquid via accessory hemiazygos vein and treated with resveratrol on spinal cord injury and evaluate the expression changes of microtubule-associated protein 2 (MAP-2) after spinal cord ischemia reperfusion injury (SCII) in swine.

METHODSEighteen swine were divided into 3 groups: group I/R (n = 6, operation group), group CL (n = 6, retrograde venous perfusion of cryogenic liquid), group CL+Res (n = 6, retrograde venous perfusion of cryogenic liquid and treated with resveratrol after ischemia). In the group I/R, the aorta was clamped for 60 minutes and then removed. In the group CL and CL+Res, 9 g/L cold (4 °C) saline solution (perfusion rate, 16.65 ml/min) was infused into the accessory hemiazygos vein during ischemia.In the group CL+Res, the swine were treated with resveratrol (10 mg/kg) after spinal cord ischemia. Arterial pressure, blood gas analysis and the spinal canal and nasopharyngeal temperature changes were monitored during the surgery. Nervous function were assessed at 6 hours, 1, 2 days, 1, 2, 4 weeks and MAP-2 expression were detected at 4 weeks after reperfusion by using Western blot analysis in spinal cord tissue.

RESULTSAfter operation 18 swine were all survival. Behavioral scores of all groups decreased until 1 week after reperfusion and increased as time went by. The scores of group CL and CL+Res were higher than group I/R (F = 8.612, 17.276 and 11.985, P = 0.035,0.011 and 0.023) at 6 hours, 1, 2 days, group CL+Res were higher than group CL(P = 0.021) at 1 days after surgery. After descending aortic cross clamping, the spinal canal and nasopharyngeal temperature were obviously decreased in all groups and dropped to the lowest at 60 minutes after ischemia and 20 minutes after reperfusion in group I/R and the other groups respectively(F = 23.187-55.029, P < 0.01).In group CL(0.54 ± 0.26) and CL+Res (0.66 ± 0.31), the MAP-2 expression were higher than group I/R(0.37 ± 0.18) (F = 9.381, P = 0.037) , and the level in group CL+Res was higher than in group CL (P = 0.021) .

CONCLUSIONRetrograde venous perfusion of cryogenic liquid via accessory hemiazygos vein and treated with resveratrol can relieve the ischemia-induced spinal cord injury in swine.

We report a rare case of progressive myelopathy caused by intracranial dural arteriovenous fistula with venous drainage into the spinal perimedullary veins. A 45-yr-old man developed urinary and fecal incontinence and muscle weakness in the lower limbs. Magnetic resonance imaging revealed brainstem edema and dilated veins of the brainstem and spinal cord. Cerebral angiography showed a dural arteriovenous fistula fed by the neuromeningeal branch of the left ascending pharyngeal artery. Occlusion of the fistula could be achieved by embolization after a diagnostic and subsequent therapeutic delay. There was no improvement in clinical condition. For the neurologic outcome of these patients it is important that fistula must be treated before ischemic and gliotic changes become irreversible.

OBJECTIVETo assess the changes of somatosensory evoked potentials (SEPs) during spinal cord ischemia and reperfusion injury and the value of SEP monitoring in evaluating neurological functions in this setting.

METHODSSpinal cord ischemia-reperfusion injury was induced in 28 rabbits by clamping the infrarenal aorta for 45 min, and the SEPs were monitored before and at 5, 10, and 15 min after ischemia, and at 15, 30, and 60 min and 2, 24 and 48 h after reperfusion. The neurological function score (NFS) of the rabbits was evaluated at 6, 12, 24 and 48 h after reperfusion, and the pathological changes of the spinal cord were observed 48 h after reperfusion.

RESULTSSEPs P1-wave latency significantly increased 5 min after ischemia (P<0.01) and the wave amplitude decreased 8 min after ischemia (P<0.01). SEPs disappeared 10 min after ischemia and recovered 15 min after reperfusion, but the P1-wave latency still remained longer and P1-wave amplitude lower than the measurements before ischemia (P<0.01). P1-wave amplitude became normal 15 min after the reperfusion (P>0.05), and the P1-wave latency gradually recovered 30 min after reperfusion, but still significantly longer than the preischemic value (P<0.01). P1-wave amplitude decreased again at 24 and 48 h after reperfusion (P<0.01). The NFS gradually increased at 24 and 48 h after the reperfusion (P<0.01). The changes in P1-wave amplitude at 24 and 48 h after reperfusion showed an obvious correlation to NFS (r=-0.881 and -0.925, respectively, P<0.01). Hemorrhage, swelling, and degeneration and neutrophil infiltration occurred in the spinal cord tissue 48 h after the reperfusion.

CONCLUSIONThe changes of SEP P1-wave amplitude can better reflect the spinal cord function than the wave latency during spinal cord ischemia-reperfusion injury, and SEP monitoring provides reliable evidence for prognostic evaluation of the neurological function.

OBJECTIVETo assess the diagnosis and treatment of venous hypertensive myelopathy (VHM) caused by narrowing of the ascending lumbar vein.

METHODThe data from 3 patients with VHM caused by narrowing of the ascending lumbar vein were analyzed retrospectively.

RESULTSOnce the narrowed site of the lumbar ascending vein was determined by myelographic or angiographic technique, an undetachable balloon was introduced and advanced to the proximal part of the narrowed segment. Satisfactory results were obtained in these patients.

CONCLUSIONNarrowing of the ascending lumbar vein is one of the causes for VHM, and endovascular balloon angioplasty is an optimal treatment.
