Objective To investigate the effect of cluster needling on scalp point about the changes of intelligences and plasma CGRP of multi-infarct dementia (MID) patients. Methods 60 cases of MID patients were divided into cluster needling and medicine groups,which were treated by hupperzine. HDS,ADL,MMSE score and CGRP content were assayed before and after treatment. Results After 8 weeks treatment,CGRP content of two groups were increased,and that of cluster needling group was increased significantly compared with control group (P

The rat anti-HRP McAbs were prepared with rat-rat hybridoma and the rat McPAP complex was made by conjugating this McAb with HRP. The results of the present work indicated that the rat MePAP can be used for detection of antibodyantigen reaction by immunohistochemical techniques and ELISA. In both assay it gave strong staining reaction for positive antigen and with background staining appeared very pale. The sensitivity of rat McPAP and HRP labelling rabbit anti-rat IgG has been compared.

Objective Apolipoprotein E(ApoE) gene polymorphism and alzheimer and coronary heart disease was studied ,and the correlation between them was evaluated.Methods The polymerase chain reaction-restriction fragment length polymorphism was used to amply 227 base-pari DNA fragment in the fourth exon of ApoE gene,and digested them with restriction enzyme CfoI,electrophoresis on 8% polyacrylamaid gel for the cleavaged products,subsequently genotype was determined by silver staining and allele frequencies were counted.Results apoE genotype and allele frequencies was detected in 33 case with Alzheimer and 37 case with coronary heart disease.The results showed that the frequencies of ApoE ? 4 was significantly higher than that in age-matched controls(P

Objective The relationship among angiotensin converting enzyme(ACE) gene polymorphism,angiotensin converting enzyme activity and coronary heart disease(CHD) was studied.Method Teh polymerase chain reaction was used to detect an insertion/deletion(I/D) of ACE gene polymorphism in the sixteen intron,then genotype and allele freqencies were counted .The method of enzyme coupling ratio was used to detect ACE activity .Results In 51 case with CHD ,the DD genotype and D allele freqencies of ACE gene were 35% and 61% respectively ,ACE average activity was (350 3?91 1)su/L.In 83 normal control subject,they were 16% and 45% and (286 7?79 6)su/L respectively.The freqencies of DD genotype and D allele and ACE average activity had significant difference.Conclusion The deletion polymorphism of ACE gene might be an latent risk factor.The higher ACE activity might play an important role in the development of CHD.

Objective To observe the effects of the third-stage community-based rehabilitation program on functional recovery of stroke patients with hemiplegia. Methods 158 stroke patients with hemiplegia were divided into rehabilitation group and control group. Besides normal medicine and first-stage institution-based rehabilitation similar with that of control, rehabilitation group received a standardized third-stage community-based rehabilitation. They were assessed with the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) and Modified Rankin Scale (MRS) before, 1 month and 6 months after treatment. Results The scores of the FMA and the MBI of the rehabilitation group were higher than that of the control group (P<0.01), while were lower of the NIHSS and MRS in the rehabilitation group than in the control group at the end of the sixth month (P<0.01). Conclusion The third-stage community-based rehabilitation may improve the recovery of the stroke patients with hemiplegia.

Objective To discuss the treatment method and effect of the application of the dorsal branches island flaps of the digital arteries in clinic.Methods During January,2010 to February,2015,a total of 20 cases of palmar soft tissue defect of the 2nd-5th distal segments of single fingers were incorporated and repaired by the dorsal branches island flaps of the digital arteries in the base of the distal phalanx.The size of the selected flaps was 3.5 cm × 2.5 cm-2.0 cm × 2.0 cm.In addition,palmar soft tissue defect (n =15) of the 2nd-5th middle and distal segments of single fingers were repaired by the dorsal branches island flaps of the digital arteries at the 1/3 site of the proximal digital arteries,and the selected flaps size was 4.5 cm × 2.5 cm-3.0 cm × 2.0 cm.Full-thickness skin graft urethroplasty was used in the donor sites.Flap shape,texture,sensory recovery and texture of the skin region,function recovery of the wounded fingers were followed up at 1,3,and 6 months after operation.Results Thirty-five patients were followed up from 6 to 13 months (average of 7 months).All flaps survived completely in the incorporated 35 cases postoperatively.Flaps had satisfactory appearance,fine texture,and soft texture in the skin transplantation area.The postoperative improvement of sensory function was between S2 and S3,and the two-point discrimination was 10-15 mm.Assessment of the upper limb function using the standard issued by the Hand Surgery Society of Chinese Medical Association graded 23 cases as excellent,10 cases as good,and 2 cases as fair.Conclusion The dorsal branches island flaps of the digital arteries are characterized by easy dissection,reliable blood supply,and no major blood vessels needed to be sacrificed,which is an effective procedure for finger soft issue defect repairing.

AIM: To investigate whether three-dimensional time-of-flight magnetic resonance angiography (3D TOF MRA) can be used as a reliable screening tool for evaluation of intracranial vascular stenosis and occlusive disease before stent implantation. METHODS: Thirty-three patients with suspected intracranial arterial stenosis received 3D TOF MRA and digital subtraction angiography (DSA) examinations in Chaoyang Hospital Affiliated to Capital Medical University between March 2007 and April 2008,and were included for this study. Two physicians blindly estimated stenosis,patient history,and clinical information of 363 vascular segments from 33 patients,including bilateral internal carotid artery (ICA),anterior cerebral artery (ACA),middle cerebral artery (MCA),posterior cerebral artery (PCA),vertebral artery,and basilar artery (BA). Stenosis was categorized as 30%-49%,50%-69%,70%-99%,and 100%. For each kind of stenosis,sensitivity,specificity,positive predictive value,negative predictive value,K and P values of MRA were calculated,respectively,as compared to DSA. RESULTS: A total of 42 diseased vascular segments were identified. Compared to DSA,for intracranial stenosis 50%-69%,3D TOF MRA showed sensitivity 100%,specificity 96.8%,positive predictive value 62.1%,negative predictive value 100%,K value 0.751,and P value 0.000; For intracranial stenosis 70%-99%,the corresponding value was 100%,98.6%,70.6%,100%,0.821,and 0.000,respectively; For intracranial stenosis 30%-49%,it was 25.0%,99.7%,66.7%,98.3%,0.356,and 0.000,respectively.CONCLUSION: For high sensitivity and specificity to intracranial stenosis 100%,70%-99%,or 50%-69%,compared to DSA,3D TOF MRA is a reliable screening tool for preoperational evaluation of intracranial vascular stenosis and occlusive disease.
