: Mild cognitive impairment (MCI) represents a transitional status between the cognition of normal aging and the fully developed clinical features of dementia. It has a high risk to progress to Alzheimer disease. Neuroimaging has become increasingly important in the clinical assessment and early diagnosis of MCI. It can also predict the course of MCI and monitor treatment effects.

Distributions of cutaneous nerves of the hand were observed by dissection methodin the 200 hands of 100 Chinese adult cadavers (male 67, female 33). Incidences ofdistribution of individual nerves on the dorsum of hands were as following: Superficialbranch of the radial nerve: 98.5?0.90%; dorsal branch of the ulnar nerve: 99.0?0.7%;lateral cutaneous nerve of the forearm: 23.5?3.00%; posterior cutaneous nerve of theforearm: 1.0?0.7%; and medial cutaneous nerve of the forearm: 1.0?0.7%. According to the range of distribution of relevant nerves, patterns of distribution ofcutaneous nerves on the dorsum of hands can be classified into 6 types. The type withthe superficial branch of the radial nerve distributing on the dorsum of radial 2(1/2) fingers,and the dorsal branch of the ulnar nerve distributing on the ulnar 2(1/2) fingers was foundin 57.0?3.5% of the 200 hands. This type was considered as the prevalent type ofChinese subjects. Cases with the ulnar nerve entirely or almost entirely substituted bythe superficial branch of the radial nerve were grouped as type V, which was found in3.5?1.3% of cases. Cases with the radial nerve completely or almost completely re-placed by the lateral cutaneous nerve of the forearm while the dorsal branch of the ulnarnerve remaining unchanged were found in 5.0?1.54% of cases. The significance ofthese rare cases was discussed. Pattern of cutaneous distributions on the palm was quite constant. In 98.5?0.85%of cases showed to be the median nerve supplying the radial 3(1/2) fingers while the ulnarnerve supplying the ulnar 1(1/2) fingers.

The axillary artery and its branches have been studied on both sides of 125 Chineseadult cadavers. The length of the three parts of the axillary artery and the distancefrom the upper border of the pectoralis minor to the origin of each branch were measuredin 44 cadavers. The average length of the axillary artery was 11.39?1.42 cm and the lengths of itsfirst, second and third portions were 1.30?0.74 cm, 2.74?0.63 cm, 7.36?0.90 cm res-pectiyely. Among the branches of the axillary arterp the origins of the lateral thoracic and sub-scapular arteries were more varied than other branches. The subscapular artery wasfound in 48.40?3.16% originated in common trunk with other branches. The incidenceof the upper subscapular artery was found in 54.80?3.15%, it may originated from anypart of the axillary artery. In considerng the incidence of the upper subscapular artery,the typical branches of the axillary artery should be seven, instead of six in textbook. A few branches belonged to the subclavian or brachial artery were found to beoriginated from the axillary artery.

Posterior ischemic optic neuropathy is a kind of ischemic optic neuropathy, the incidence rate of which is lower with less obviously clinical features, less positive signs and more difficultly diagnosis when compared with anterior ischemic optic neuropathy.Meanwhile, therapeutic method of posterior ischemic optic neuropathy has remained controversial.This article will summarize the research development of the auxiliary examination, diagnosis, differential diagnosis and therapeutic method of posterior ischemic optic neuropathy.

Nerve root compression due to ligamentum flavum hematoma is extremely rare, with less than 70 cases reported in the literature. The clinical presentation and images were similar to those of spinal epidural tumors. Herein, we reported a previously healthy 64-year-old female who presented with right radicular leg pain. Neurological examination was consistent with right L5 root compression. The magnetic resonance imaging revealed a mass posterior to the L5 thecal sac, appearing as high intensity on T1-weighted and T2-weighted images. During operation, the dark hematoma within the ligamentum flavum was found. The pathological examination confirmed the diagnosis of hemorrhage. Her prognosis following surgery was excellent.

Objective To evaluate the relationships between the unstable coronary lesions and the levels of serum C-reactive protein(CRP) and urico-acid (UA).Methods 205 patients with primary diagnoses as coronary heart disease were examined by selective coronary angiography,and in the mean time ,the serum CRP and UA levels were measured.These patients were grouped the control,the unstable coronary lesion group and stable coronary lesion group according to the extent of coronary artery atherosclerosis stenosis.All data were undergone statistical analysis.Results The serum CRP level in unstable coronary lesion group was higher than that in stable coronary lesion group(P0 05).Conclusions The serum CRP level is significantly positive relation with the unstable coronary lesions.The serum UA level is not association with the unstable coronary lesions.
