Objective To evaluate the clinical usefulness of MR imaging(MRI) and MR tomography angiography(MRTA) in demonstrating the presence and degree of neurovascular contact of the rostral ventrolateral medulla oblongata(RVLM) in root entry zone of the 9th and 10th cranial nerves in patients with essential hypertension(EHT) and normotensive health volunteers(NTHV).Methods(Patients with) EHT(group 1,n=100) and NTHV(group 2,n=88) underwent high-resolution(axial and coronal) brain stem MRI and MRTA.Images were interpreted consensually by tow radiologists who were blinded to the patients hypertensive status.Neurovascular contact was graded as vessel contact without RVLM deformity(gradeⅠ),clear vessel contact in continuity with the brain stem but without apparent associated deformity(graded Ⅱ), and displacement contact of the RVLM(graded Ⅲ).Results(Neurovascular) contact of RVLM was found in 52.0%(52/100) of EHT and in 43.2%(38/88) of NTHV(?~2=1.459,P=0.230).The compression rate(gradeⅠ—Ⅲ) and affected side(left or right) showed no statistically significant differences between the EHT and NTHV(?~2=0.879,P=0.350;?~2=0.238,(P=0.628);?~2=0.733,P=0.390).Conclusion Neurovascular contact is not more frequently seen in patients with EHT than in normotensive contact subject.This result does no support the hypothesis that neurovascular contact at the RVLM is an etiology of EHT.Furthermore,thin-slice(3 mm) MRI may not be a reliable good screening method for detecting patients with neurovascular contact.Therefore,MRI cannot aid patient selection among hypertension patients lacking symptomatic cranial neuralgias.

OBJECTIVETo explore the distribution features of Chinese medical constitutions in different ages population, thus providing scientific evidence of constitution process theory.
METHODSRecruited were 21 948 cases from a survey of Chinese medical constitutions and health conditions in 9 provinces or municipalities across China (including Jiangsu, Anhui, Gansu, Qinghai, Fujian, Beijing, Jilin, Jiangxi, and Henan) from Dec 2005 to Jan 2007. The body constitution type of individual was diagnosed using discriminant analysis on the basis of Chinese medical constitution questionnaire. By using correspondence analysis, the correlation between the general population, genders, ages, and Chinese medical constitution types was studied.
RESULTSConstitutions of yin-deficiency type, wetness-heat type, qi-depression type, and special diathesis type often occurred in the population ranging 15 -24 years old. Gentleness type mostly occurred in the population ranging 25 -44 years old. During this time period, phlegm-wetness type and wetness-heat type were liable to occur in males, while blood-stasis type was liable to occur in females. Qi-deficiency type and yang-deficiency type were most often seen in those older than 45 years. Phlegm-wetness type and blood-stasis type body constitution were also liable to occur in those older than 45 years.
CONCLUSIONSThe distribution features were different in different Chinese medical constitutions. Different constitution types exist in different genders. Different constitution types exist different ages population.

AlM: To explore the judgment of pattern reversal visual evoked potential on visual function and injured part of children with spastic cerebral palsy.METHODS: There were two groups in this study. 30 children with spastic cerebral palsy ( quadriplegia: 15, diplegia:15) were selected as observation group, while 30 normal children were selected as control group with randomized controlled trial. The changes of half-view and full- view incubation period and amplitude were observed by pattern reversal visual evoked potential.RESULTS: Full-view pattern reversal visual evoked potential: the P100 incubation period of the observation group was 113. 55 ± 8. 14ms, and the P100 amplitude was 23. 08±15. 41μV. The P100 incubation period of the control group was 105. 05 ± 5. 58ms, and the P100 amplitude was 31. 65±7. 37μV. From the comparison on P100 incubation and P100 amplitude between two groups, the difference was statistically significant ( P<0. 05 ) . P100 incubation period of the spastic diplegia of full-view pattern reversal visual evoked potential was 112. 73±7. 22ms, and the P100 amplitude was 21. 03±12. 17μV. P100 incubation period of the spastic quadriplegia was 114. 37 ± 9. 02ms, and the P100 amplitude was 25. 14 ± 18. 06μV. From the comparison on P100 incubation and P100 amplitude between two groups, the difference had no statistically significance (P>0. 05). Compared to the control group, each eye and each view latency of observation group were higher, the difference was statistically significant ( P<0. 05). The change of the incubation period of the full-view and half - view pattern reversal visual evoked potential took place in the lesion of the visual pathway:including optic neuropathy, some optic nerve lesion, lesion after optic chiasma, and optic chiasma lesion. Among them, the lesion after the optic chiasma was the most common.CONCLUSlON:Pattern reversal visual evoked potential can help people to understand the visual impairment and injury of children with spastic cerebral palsy in order to identify the abnormal children and early intervention.

BACKGROUND: Recently, Chinese herb and comprehensive therapy are widely adopted for the treatment of chronic atrophic gastritis (CAG), while infrared ray is widely used in the fields of physical therapy and scientific research. Therefore, some scholars suggest whether the physical characteristics of infrared ray have effects on the treatment of chronic atrophic gastritis.OBJECTIVE: To observe the effect of infrared ray on the changes of gastric mucosa tissue in rat models with chronic atrophic gastritis.DESIGN: Randomized controlled observation.SETTING: Hebei North University.MATERIALS: Thirty-five adult Wistar male rats weighing from 180 to 230 g were purchased from Hebei Experimental Animal Center [SCXK (ji) 2003-1-003]. The experiment was disposed with the ethical standard. Sodium salicylate powder produced by Beijing Fangcao Chemical Company (batch number: 890720). The drug was prepared with distilled water. Infrared lamp (220 V, 200 W) was bought by Equipment Division of our college.METHODS: The experiment was carried out in the Experimental Center of Hebei Beifang College from June 2005 to January 2006. ① Experimental intervention: Rats were fed with conventional standard granules for one week. Among them, 8 rats were selected as the normal control group, and other rats underwent model establishment. Rats were perfused with sodium salicylate and alcohol to stimulate gastric mucosa, and then chronic CAG models were established for 8 weeks based on exertion, irregular diet and other factors. Five rats were randomly selected for the check of histopathology before the end of model confirmedly making, and then the model rats were randomly divided into model group and infrared group with 11 in each group. Infrared lamp (220 V, 200 W, 0.76–1.5 μm in wavelength) was used to vertically radiate at the gastric projective area of rats in the infrared group, once a day, ten minutes once for twenty days. The rats in normal group and model group were regularly breed. ② Experimental evaluation: The body mass was weighed every week in 1, 4, 9 and 12 weeks after modeling. The infiltration of inflammatory cells and thickness of gastric mucosa were observed under optic microscope.MAIN OUTCOME MEASURES: ① Changes of body mass; ② pathohistological changes of gastric mucosa.RESULTS: All 30 rats were involved in the final analysis. ① Changes of body mass: From the end of the 4th week, increasing percentage of body mass in the model group and infrared group was decreased gradually as compared with that in the normal group, and there was significant difference (P < 0.05). ② Pathohistological changes of gastric mucosa: Gastric mucosa of rats in the model group was thinner, and atrophic glands, notable inflammatory infiltration and partial intestinal metaplasia were observed under optic microscope. The thickness of gastric mucosa in the infrared group was significantly thicker than that in model control group, and there was significant difference (P < 0.01); the inflammatory cells in the infrared group were less than those in the model group, and there was significant difference (P < 0.05). Morphologic structure and volume of the parietal cells were all recuperated or closed to normal.CONCLUSION: Infrared ray can decrease thickness of gastric mucosa and reduce inflammatory cells of rats with chronic atrophic gastritis, and it has greatly therapeutic achievements.
