Objective:To investigate the onset mechanism of cervical vertigo from the proprioceptive sensation and provide clinical basis for its treatment.Methods:Among the 121 cases that conformed to the diagnostic criteria of cervical vertigo,70 cases who presented with negative neck-rotation test and cervical vertigo without obvious vascular factors by transcranial Doppler(TCD)were assigned to the observation group,while 51 cases who presented with positive neck-rotation test and cervical vertigo due to spasm of vertebral basal artery or insufficient blood supply by TCD were assigned to the control group.The cases in the two groups were treated once every day,5 days make up one treatment course and the resuIts were statistically analyrzed after one treatment course.Results:The skull triaxial spatial offset of the cases in the two groups were significantly reduced after the treatment (P<＜0.01).However, there was no statistically significant difference between the skull triaxial spatial offset between the two groups (p＞0.05).It is not conclusive that the therapeutic effect in the two groups was significantly different after one treatment course.Conclusion:Tuina manipulation therapy can improve the skull spatial ofrset repositioning ability of the Patients.

On the basis of the investigation of the pathogenesis of cervical spondylotic radiculopathy, this paper studies the mechanisms of spinal micro-adjustment manipulations in recovering and improving cervical dynamic and stationary balance from the perspective of biomechanics.

Thirty-three infants with muscular torticollis were treated by Tuina techniques, and the size of the hardened sternocleidomastoid muscle in the affected side was B-ultrasonographically observed before and after treatment. Results: 27 cases were cured, 5 cases got effectiveness, 1 case failed and the total effective rate was 97.0%; B-ultrasonography, in the palpable cord-like or ovary-like lumps,showed low echo in 28 cases, moderate echo in 2 cases and high echo in 3 cases; there were significant differences in the length, thickness and width of the lumps between before and after treatment, P＜0.01. It is indicated that Tuina is quite effective against infantile muscular torticollis; that ultrasonography can be adopted as an objective item for the evaluation of the clinical efficacy of Tuina in the treatment of infantile muscular torticollis, and it is a simple, convenient and inexpensive method and should be extensively popularized in clinical practice.

Objective To investigate the relationship between infection of helicobaeter pylori(Hp) and iron deficiency anemia(IDA) and to explore effective clinical treatments for patients with Hp associated IDA . Method 1. The Hp infection ratio of 40 chronic gastritis with IDA and 42 patients without IDA were counted up respectively. 2. 36 patients with Hp-positive chronic gastritis were divided into two groups randomly. One group was treated by using Hp eradication therapy in conjunction with oral iron supplement and the other using iron supplement only. The hema-tological parameters before and after treatment are measured and the effectiveness of the treatment was evaluated. Re-sult The Hp infection ratio in chronic gastritis patients with IDA is |figher than that in patients without IDA and the difference is significant. After Hp eradication therapy in conjunction with iron supplement Hb. serum iron and serum ferritin level in Hp associated IDA patients are increased significantly while that for patients treated by using iron sup-plement only have no significant improvement. Conclusion It appears that Hp infection may be related to IDA. When iron supplement treatment has no obvious effect to an IDA patient,lt may suggest a ease of Hp associated IDA. The i-ton supplement treatment has positive effects to IDA patients after Hp eradication.

Objective To establish the carotid fusiform aneurysm model in rabbits carrying similar characteristics of human intracranial aneurysms by using induction method with porcine pancreatic elastase. Methods Twenty-five New Zealand white rabbits were randomly divided into normal control group (n=5), saline control group (n = 5) and study group (n = 15). The rabbits of the study group were randomly and equally subdivided into 7-day subgroup, 14-day subgroup and 21-day subgroup. By using induction method with porcine pancreatic elastase to digest right common carotid the fusiform aneurysm model was established in all the rabbits of the study group. DSA examination , HE staining and elastic fiber staining pathologic examination were carried out at 7, 14 and 21 days after the procedure to observe the imaging and pathologic changes of the fusiform aneurysm models. Results DSA angiography showed that the mean vascular diameters of the normal control group and the saline control group were (1.64 ± 0.17) mm and (1.66 ± 0.24) mm respectively. The mean length and width of the fusiform aneurysm of the 7-day subgroup, 14-day subgroup and 21-day subgroup were (19.33 ± 1.65) mm and (2.86 ± 0.21) mm, (19.66 ± 1.18) mm and (3.95 ± 0.54) mm, and (19.84 ± 0.82) mm and (4.03 ± 0.95) mm, respectively. Pathologically, rupture of internal elastic membrane, disordered structure of tunica media smooth muscle and distortion of cell shape were observed in the rabbits of 7-day subgroup. Gradually stabilized aneurysmal lumen intimal hyperplasia was seen in the rabbits of 14-day subgroup. Remarkable structure changes at the aneurysmal neck-cavity junction were found in the rabbits of 21-day subgroup. Elastic fiber staining demonstrated that strikingly thinned elastic layer was observed in the rabbits of 7-day subgroup, gradually thinning elastic layer at the aneurysmal neck-cavity junction was seen in the rabbits of 14-day subgroup, and the thinned elastic layer became stable in the rabbits of 21-day subgroup. Conclusion Using simple surgical method combined with porcine pancreatic elastase to digest vascular wall, carotid fusiform aneurysm models can be reliably established in New Zealand white rabbits which carry similar morphologic and pathologic characteristics of human intracranial aneurysms.

Objective To investigate the feasibility and effectiveness of inducing rabbit common carotid fusiform aneurysms via the common carotid extravascular digestion method. Methods Sixteen New Zealand white rabbits were randomly assigned into either an experiment group ( n=12 ) or a control group (n=4). Porcine pancreatic elastase 80-400 U were used to incubate and digest 2 to 4 cm segment of artery distal to the origin of right common carotid artery. One week after modeling,intravenous angiography was performed and the length and width of fusiform dilatation of common carotid artery were measured. The fusiform dilated artery was examined with hematoxylin and eosin staining and the vascular morphological changes were observed with scanning electron microscope. Isotonic saline solution was used to incubate common carotid arteries of the 4 New Zealand white rabbits in the control group. After one week,the same method was used to observe the lumen of common carotid artery and intimal changes. Results After the digestion of common carotid artery adventitia,the angiography of 12 New Zealand white rabbits of the experimental group revealed fusiform dilatation of common carotid artery of the 10 model rabbits. The widest diameter of the fusiform artery was 3. 70 ± 0. 32 mm;two rabbits had common carotid artery occlusion. Compared with the control group,the right common carotid artery diameter enlarged significantly in the experimental group (1. 80 ± 0. 16 mm,P<0. 01). The HE staining showed that the lumen widened, adventitia and media reduced. Scanning electron microscope showed intimal inflammatory injury and thrombus attachment. Conclusion Using porcine pancreatic elastase to digest the adventitia of common carotid artery can make fusiform dilatation of common carotid artery in rabbits. Using this method may effectively induce a model of fusiform aneurysm,and it has certain feasibility.
