External hard disk with USB interface is used to storage CT raw data so as to solve the question that CT raw data cannot be storage for long time. This method benefits CT clinical work and scientific research. Compression and storage of CT raw data will play an important role in CT data storage.

Objective To observe the clinical efficacy of acupuncture at the trigger points on the back in treating cardioneurosis. Methods Fifty patients with cardioneurosis were selected to receive syndrome differentiation of traditional Chinese medicine, and then were evaluated for the improvement of symptoms respectively after first acupuncture treatment at the trigger points on the back and after 3~5 acupuncture treatments. Results Of the 50 cardioneurosis patients, 30 showed marked effect, 14 showed effective, 6 failed in the treatment, and the total effective rate was 88.0%. The total effective rate was 96.2%in patients of deficient heart yang, and was 75.0%in those of excessive fire due to yin deficiency, 83.3%in those of qi stagnation due to liver depression, and 83.3%in those of deficient heart yin. The improvement rate of subjective symptoms after 3~5 treatments was significantly different from that after the first treatment (P<0.05). Conclusions Acupuncture at the trigger points on the back is an effective approach in treating cardioneurosis, and it can achieve a marked efficacy with successive 3~5 sessions.

Objective: To evaluate the application value and potential faults of Dual-source CT in carotid arterial angiography.Methods: We retrospectively analyzed the images of 477 patients with symptomatic carotid atherosclerosis detected by dual-source CT angiography(CTA) from February 2007 to January 2008,and evaluated the quality of the images,which were classified into 3 quality grades: excellent(with clear display of the lesion and no noticeable motion artifacts,good(with a few motion artifacts but still diagnostically applicable),and poor(with heavy motion artifacts,unclear display and no diagnostic value).Results: Of the 477 images,420(88.1%) were of excellent quality,44(9.2%) of good quality and 13(2.7%) of poor quality.Among the total number of cases,134(28.1%) were shown to be normal and 34(7.1%) abnormal in anatomic structure.Atheromatous plaques were detected in 295 cases(61.8%),carotid artery stenting in 11(2.3%),internal carotid artery occlusion in 1,common carotid artery occlusion in 1,and cervical tumor in 3.Conclusion: Dual-source CT,faster,effective and minimally invasive,is particularly valuable in the diagnosis of carotid arterial lesion and stenosis.

Objective To evaluate the result of percutaneous transluminal stenting angioplasty(PTSA) to high degree stenosis of internal carotid artery. Methods PTSA was attempted in eight patients with high degree stenosis of internal carotid artery from January 1998 to October 1999. Three types of stent were used for the procedure. After proper preparation, we selected different type of stent and special procedure method according to the patient's lesion. Results Nine stents were implanted in eight internal coratid arteries of nine patients. All cases were successful based on post procedure image, and recovery from neurologic symptoms was satisfactory. Conclusion (1) PTSA is a safe and reliable procedure to treat high degree stenosis of internal carotid artery. (2) It is important to select the appropriate type of stent and the special method according to the individual situation.

Objective To analyze the cost-effectiveness of integrated pharmaceutical care (IPC) in community-based patients with chronic obstructive pulmonary disease (COPD).Methods The COPD patients were divided randomly into intervention group (group A,n =79) and control group (group B,n =71).Group A received the IPC intervention measures,including serial lectures of pharmaceutical knowledge,home supervision and web-based communications for while group B group had none.Results As compared with group B,group A obviously improved on the knowledge of pharmaceutical treatment effect and side effect (95.1％,67.4％ vs.63.1％,21.9％,x2 =12.445,P=0.000 vs.x2 =55.557,P=0.000).There were notable differences between two groups [ ( 1.77 ± 1.23 ) vs.( 2.42 ± 1.66 ) s,t =2.583,P=0.011],pulmonary rales [ (0.01 vs.0.01)s,Z =2.370,P=0.018],6-min walk distance (6 MWD) [ (457 ± 67 ) vs.(425 ± 72) m,t =2.760,P =0.007 ],vital capacity ( VC ) [ ( 1.60 ± 0.25 ) vs.( 1.49 ± 0.23 ) L,t =2.718,P =0.007 ) ] andquality-of-life items ( 48 ± 10 vs.52 ± 11,t =2.624,P =0.010) after intervention.Analyze of cost-effectiveness show that groupA was superior to group B [ total effect total cost(TE/TC =764.6/4936,15.49％ )vs.(TE/TC =1509.4/4708),32.06％,x2 =6.183,P ＜ 0.01 ].Conclusion IPC can improve the disease condition and achieve excellent cost-effectiveness for community-based COPD patients.

Objective To discuss the feasibility and long-term effect of free latissimus dorsi muscle flap in repair of severe lower extremity injury in children. Methods From July 1999 to June 2004, nine child patients (at age of 6-13 years) with severe lower extremity injury involving soft tissue defects a-round the calf and the foot associated with complex open fractures, bare dislocation, and injury of the nerve, tendon and artery were repaired with free latissimus donsi flap, with flap area ranging from 30 cm ×12 cm to 10 cm × 5 cm. Results All the latissimus dorsi flaps survived, with success rate of 100%. A follow-up for 4-9 years showed that the flap had sound shape and function and normal blood supply, without significant influence on donor area. Conclusion Latissimus dorsi flap has advantages of constant anatomical site, abundant blood supply, massive area, strong anti-infection ability and less in-fluence on donor area and hence is an ideal method for repairing severe lower extremity injury in children.

Objective Analysis of MRI image of lateral ventricular subependymomas to improve our recognition of radiology manifestation of the disease. Methods Clinical data and MRI findings of 6 patients with subependymomas proved by surgical pathology, observed from January 2007 to June 2013, were analyzed retrospectively. Results Six patients (4 males and 2 females) presented with headache and dizziness. Among these 6 patients, tumor developed in right lateral ventri-cle in three patients, in left lateral ventricle in 2 patients and in frontal of dual lateral ventricle in one patient. In MRI image, tumors showed iso-intense to hypointense to normal white matter on T1-weighted and DWI images, hyperintense on T2-weighted and FLAIR. Mild or no enhancement was noted in most cases. MRS showed findings consistent with low-grade tu-mor, with a normal choline peak and depressed N-acetyl-aspartate peak. Conclusion Lateral ventricular subependymo-mas have characteristic MRI features and multi-direction images are helpful for diagnosis.

Objective The purpose of this study is to evaluate Surgical Procedure and Prognosis for elderly stage 1NSCLC patients above 70 years old.Methods The patients who were stage Ⅰ non-small cell lung cancer from 2003 to 2007were enrolled ( n =71 ).The median age was 74 years ( ranged from 70 to 84 years).The median follow-up of patients was 30months( ranged from 2 to 81 months).Results The percentages of postoperative complications after sublobar resection and lobectomy patients were 36.4％ and 46.9％,respectively.The period in hospital were 11.36 days and 12.24 days.The 3 year survival was 85.9％ for patients undergoing sublobar resection and 78.8％ for lobectomy.The 5 year survival was 56.4％ and 56.9％ respectively.No significant difference was observed between two types of surgical procedure in the elderly.Staging is the independent factor of prognosis.Conclusion Lobectomy is still the main therapy method for elderly stage Ⅰ NSCLC patients.Especially,for those who can undergo radical resection.But sublobar resection also appears to be a viable surgical treatment for patients with cardiopulmonary physiologic impairment.

Objective To research the activated brain areas of decision making under uncertainty reward processing on healthy volunteers.Method The E-Prime programs were presented 3 kinds of tasks of the decision under uncertain reward processing.15 right-handed healthy volunteers made a response after receiving the task.At the same time,the GE 3.0T magnetic resonance scanner scanned the brains areas of subjects.Individual analysis and group analysis was done with SPM8 software,then the brain activating regions and the peak intensity were gotten.Results Orbitofrontal cortex was activated in certainty,peak intensity 2.4328 ± 0.1949 (P ＜ 0.05).Prefrontal cortex,occipital lobe,parietal lobe,posterior lobe of cerebellum,limbic lobe and midbrain were activated under the risk reward processing,peak intensity 2.4228 ± 1.3762 (P ＜ 0.05).When under ambiguity reward processing,prefrontal cortex,temporal lobe,occipital lobe,left inferior frontal gyrus and posterior lobe of cerebellum were activated,peak intensity 2.4056 ± 0.4222 (P ＜ 0.05).Compared with the task under certainty,posterior lobe of cerebellum,gyri subtemporalis and gyri fusiformis,inferior parietal lobule,anterior central convolution,orbitofrontal cortex,ventrolateral prefrontal cortex,both frontopolar and supramarginal gyrus were activated in task under risk (P ＜0.05) ;and both frontopolar were activated in task under ambiguity (P ＜ 0.05).Compared with the task under risk,dorsolateral prefrontal cortex and posterior lobe of cerebellum were activated in task under ambiguity (P ＜ 0.05).Conclusion There are differences in different types of reward processing of decision making.
