OBJECTIVE: To explore the mechanism of microvascular spasm after limb ischemia-reperfusion. METHODS: The rabbit hindlimb normothermic tourniquet ischemia model was employed. The tendon on the dorsum of the foot was exposed for observation of microvessels. The responses of arterioles on tendon surface to topical application of 10(-6) mol/L noradrenaline (NE) (a vasoconstrictor), 10(-6) mol/l acetylcholine(Ach) (an endothelium-dependent vasodilator) and 10(-4) mol/L nitroglycerin(NTG) (an endothelium-independent vasodilator) were observed at the period of ischemia and following 30 minutes of reperfusion after 2 hours and 5 hours of ischemia by use of intravital microscopy. RESULTS: No significant changes in the responses of arterioles to NE, Ach and NTG were noted following 30 minutes of reperfusion after 2 hours of ischemia compared with pre-ischemia. The constrictor responses of arterioles to NE were still not significantly altered following 30 minutes of reperfusion after 5 hours of ischemia, however, the dilation responses to Ach and NTG were significantly decreased (to Ach P lt; 0.01; to NTG, P lt; 0.05). CONCLUSION: Reperfusion after 5 hours of ischemia significantly impairs both the endothelium-dependent and endothelium-independent vasodilation, meanwhile preserves constrictor responses to NE, these may contribute to the genesis of the vasospasm in ischemia reperfusion.
Objective To explore the effects of propofol and thiopental sodium injection on convulsive seizure in electro-convulsive therapy(ECT) and to provide evidence to help the selection of intravenous anaesthetics in improved ECT. Methods Total of 111 patients who received ECT in the 3rd Pepole’s Hospital of Panzhihua from July to December 2005 were divided into a thiopental sodium group (n =62) and a propofol group (n =49). These patients received intravenous anaesthesia with suxamethonium plus thiopental sodium or propofol for the implementation of ECT, respectively. The status of convulsive seizure was compared between the two groups. Results There were no significant differences between the two groups in terms of main demographic data, disease category and ECT parameters (Pgt;0.05). Motor seizure and electricity discharge lasted significantly longer in the propofol group than in the thiopental sodium group (Plt;0.01). Conclusion Thiopental sodium can increase the excitation threshold of brain cortical neurons and decrease the level of convulsive seizure induced by ECT. Propofol may decrease the excitation threshold, and increase the level of convulsive seizure under the same ECT parameters, but may have the potential to induce epileptic seizure.
ObjectiveTo explore the differences in the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences, so as to further guide the clinical understanding of VABAM and improve the appropriate imaging sequences. MethodsA total of 353 patients with infantile spasm or epileptic spasm who were admitted to the Epilepsy Center of Yuquan Hospital of Tsinghua University from January 2020 to January 2023 were retrospectively included. MRI was performed in 131 cases, including 3D T1, T2, T1- fluid-attenuated inversion recovery sequence (FLAIR) images, DWI and ADC sequences, of which 65 cases taking VGB. We aim to evaluate the detection of vigabatrin-associated brain abnormalities on MRI by different MRI sequences in these children. Results Among the 65 patients, VABAM was detected in 23 cases, the detection rate was 35.4%. The average dosage of vigabatrin was 100.73±35.54 mg/(kg·d). The positive detection rates of VABAM were 95.7% in DWI sequence, 26.1% in ADC sequence, 21.3% in FLAIR sequence, 4.3% in T2 sequence and 0 in T1 sequence. The detection rate of ADC sequence was significantly different from DWI sequence and T1 sequence, but not from T2 sequence and FLAIR group. ConclusionDWI sequence has irreplaceable advantages in the detection rate of VABAM. Therefore, for patients with infantile spasm and epileptic spasm who take vigabatrin, we should try our best to add DWI sequence scanning to improve the positive detection rate and avoid clinical symptoms, so as to avoid further brain damage.
Objective To observe the effect of selective sacral rhizotomy in treating spastic bladder after spinal cord injury and to explore the mechanism and the best surgical method of different sacral rhizotomies. Methods The spastic bladder models were established in 12 male dogsand were divided into 4 groups according to the different rhizotomies of the sacral nerve as the following: rhizotomy of the anterior root of S2(group A), rhizotomy of the anterior root of S2 and half of the anterior root of S3(group B), rhizotomy of the anterior roots of S2 and S3(group C), and total rhizotomy of the nerve roots of S2-4 (group D). By urodynamic examination and electrophysiological -observation, the changes of all functional data were recorded and comparedbetween pre-rhizotomy and post-rhizotomy to testify the best surgical method. In clinical trial, according to the results of the above experiments, rhizotomy of the anterior root of S2 or one of the halfanterior root of S3 were conducted on 32 patients with spastic bladder after spinal cord injury. The mean bladder capacity, the mean urine evacuation and the mean urethra pressure were (120±30), (100±30)ml and (120±20) cm H2 O, respectively before rhizotomy. Results After rhizotomy, the bladder capacity in 4 groups amounted to (150±50), (180±50), (230±50), and (400±50) ml, respectively; and the urine evacuation volume were (130±30), (180±50), (100±50) and (50±30)ml, respectively. In the treated 32 patients, the mean bladder capacity were raised to 410 ml, and the mean urine evacuation volume were also increased to 350 ml. Incontinence of urine disappeared in all patients. After 22-month follow-up on 13 patients, no recurrence was observed. Conclusion The effectof selective sacral rhizotomy in treating spastic cord injury is significant and worthy of further studies.
To quantitatively evaluate the upper-limb spasticity of stroke patients in recovery stage, the relationship between surface electromyography (sEMG) characteristic indexes from biceps brachii and triceps brachii and the spasticity were explored, which provides the electrophysiological basis for clinical rehabilitation. Ten patients with spasticity after stroke were selected to be estimated by modified Ashworth (MAS) assessment and a passive elbow sinusoidal motion experiment was carried out. At the same time, the sEMG of biceps and triceps were recorded. The results shows that the reflex electromyographic threshold could reflect the physiological mechanism of spasticity and had significant correlation with MAS scale which showed that sEMG could be prosperous for the clinical quantitative evaluation of spasticity of stroke patients.
ObjectiveTo explore the clinical manifestation, diagnosis, treatment and prognosis of infantile spasm complicated with craniostenosis.MethodsA case of infantile spasm complicated with craniostenosis in the Department of Neurology of Qilu Children's Hospital in December 2017 was reviewed with the literature. The clinical manifestations, diagnosis, treatment and prognosis of infantile spasm with craniostenosis were analyzed.ResultsThe proband infantile spasms and craniostenosis was diagnosed by clinical, imaging examination and VEEG. Epileptic attack was prevented and craniostenosis was corrected by hormone shock therapy (corticotrophin was administered for 14 days, followed by topiramate)and surgical treatment (cranial cap reconstruction was performed), and good clinical prognosis was obtained.ConclusionThis case was the first reported case of craniostenosis with infantile spasm in China, and compared with the foreign treatment method, better treatment method and the operation opportunity were obtained. Which has a significant effect on the clinical treatment of infantile spasm complicated with transcranial disease.
