Objective To analyze the clinical manifestations as well as correlation between clinical manifestations and the new neuroimage characteristics(pontine"cross sign"and"putaminal slit")for correct diagnosis of multiple system atrophy(MSA).Methods Eleven patients with MSA based on Gilman diagnostic criteria were retrospectively analyzed for clinical manifestations and brain MRI findings.Results Eleven patients were probably diagnosed as MSA,among which 8 patients were MSA-C(olivopontoeerebellar atrophy,OPCA),2 patients were MSA-P(striatonigral degeneration,SND),one patient was MSA-A(Shy- Drager syndrome,SDS).Five years after onset,MRI of MSA-A showed stage 0"cross sign"and "putaminal slit".In 8 patients with MSA-C,2 patients reached stage Ⅰ 3 years after onset,one patient reached stage Ⅱ 2 years after onset,3 patients respectively did stage Ⅲ 1 year,3 years,and 5 years after onset,2 patients reached Ⅳ stage 2 years,and 7 years after onset respectively.As for putaminal slit,all of these patients were in stage 0.One patient with MSA-P reached stage 0"cross sign"and stage Ⅰ "putaminal slit"6 years after onset;another patient showed stage Ⅳ"cross sign"and stage Ⅱ"putaminal slit"9 years after onset,which was high slit intensity on both sides,however much stronger in the fight side than in the left side.Conclusion Both"cross sign"and"putaminal slit"are neuroimage characteristics for early diagnosing MSA-C,while"putaminal slit"for MSA-P.

Objective To discuss and to compare the curative effects of interventional embolization with different embolic agents in treating giant hepatic cavernous hemangiomas. Methods From 2008 to 2010, a total of 30 cases with clinically proved hepatic cavernous hemangioma were treated with interventional embolization. According to the embolic agents used , the patients were divided into pingyangmycin-lipiodol emulsion mixed with sodium alginate microspheres group(PLE+KMG, group A, n=15) and pingyangmycin-lipiodol emulsion group (PLE, group B, n=15). CT scanning was performed one, 3, 6, 12 months after the treatment to evaluate the curative effect. Results The technical success rate was 100%in both groups. The mean PLE dose used in group A and B was (10.9 ± 5.2) ml and (11.4 ± 4.9) ml respectively, the difference between the two groups was not significant (P > 0.05). CT reexamination performed one, 3, 6 months after the treatment showed that a reduction in tumor volume over 50%in group A was seen in 9, 11 and 14 cases respectively, while in group B it was 0, 3 and 5 cases respectively (P <0.05). One week after the procedure, the degree of pain in patients of group A was more severe than that in patients of group B, the difference between the two groups was statistically significant (P < 0.05). Slight abnormal hepatic function was seen in some patients of both groups, which presented mainly as an elevation of aminotransferase, which returned to normal after symptomatic medication. Follow-up with questionnaire indicted that patients of group A were more satisfied with the treatment than the patients of group B. Conclusion Transhepatic infusion of pingyangmycin-lipiodol emulsion is a safe and effective treatment for giant cavernous hemangioma of the liver. Combination use of pingyangmycin-lipiodol emulsion and sodium alginate microspheres can obviously reduce the tumor size mainly in the first and the third month after the treatment, besides it produces instant clinical effect although the pain is more severe than in patients treated with pure pingyangmycin-lipiodol emulsion.

Fluid-attenuated inversion recovery vascular hyperintensity (FVH) is a common magnetic resonance imaging findings in acute ischemic stroke due to severe stenosis or occlusion of large cerebral arteries.This article reviews the applications and related research of FVH in patients with acute ischemic stroke.

Although chemotherapy is an effective way for advanced gastric cancer ,it does not significant-ly improve the prognosis of patients .Recently ,further researches on the mechanism of gastric cancer have led to the identification of ′driver gene′and the development of new agents that target these genes .By inhibiting the hu-man epidermal growth factor receptor 2(Her-2)for advanced gastric cancer ,it provides a new treatment for pa-tients.Trastuzumab is a kind of Her -2 monoclonal antibody ,it is the first kind of targeted therapy drug for the treatment of advanced and metastatic gastric cancer .A combination of trastuzumab with cisplatin and fluorouracil based chemotherapy can benefit patients overall survival .Therefore,in this paper,we make a review and summary of a set of recent studies related to the gastric targeted therapy .

OBJECTIVETo further explore the effect of Jiangu Erxian Pill (JGEXP) on proliferation and cell cycle of human osteoblast on the basis of previous clinical and experimental studies.

METHODSHuman primary osteoblast were isolated and cultured. The cell proliferation was tested by 3H-thymine incorporation and methyl thiazolyl tetrazolium (MMT) method and the cell cycle was determined by flow cytometry technique.

RESULTSIn the medium and high dosage JGEXP groups, the cell proliferation rate and index, and percentage of diploid synthesis phase (S phase) cells were significantly higher than those in the blank control group (P < 0.01 or P < 0.05), and similar to those in the estrogen group; and the cell apoptosis rate and percentage of G0-G1 stage cells were lower than those in the blank control group (P < 0.01 and P < 0.05).

CONCLUSIONJGEXP could effectively promote the cell proliferation and differentiation, and prevent the cell apoptosis of osteoblast in vitro.

Cardiac pacing is an effective treatment for cardiac pacing and conduction dysfunction and severe heart failure. However， the conventional right ventricular pacing may increase the incidences of heart failure and atrial fibrillation， and biventricular pacing has a relatively high non-response rate. As a new technique of physiological pacing， a number of studies in recent years have been conducted to show the stability of pacing parameters and good cardiac synchronization of his-purkinje system pacing. This article reviews the current status of research and progress in the effects of his-purkinje conduction system pacing on cardiac function， so as to provide a theoretical basis for promoting the development of this technology.

Objective To investigate the effect of HSP70/CD80 DNA vaccine on the airway inflammation and hyperresponsiveness of asthmatic mice. Methods Forty female healthy BALB/c mice were randomly divided into 4 groups; saline group, asthma group, pcDNA3. 1 plasmid control group, and prevention group with HSP70/CD80 DNA vaccine, with 10 mice in each group. The mice were immunized by intramuscular( i. m. ) injection with HSP70/CD80 DNA vaccine before sensitization and challenge with ovalbumin. Then, the murine model of allergic asthma was made with injection of ovalbumin intraperitoneal ( i. p. ) , and inhalation of ovalbumin. Before mice were sanctified, their airway hyperresponsiveness( AHR) was measured. After mice were sanctified, bronchoalveolar lavage fluid( BALF) was obtained and cytokine IL-13 and IFN-γ were measured. And the lung histology and histochemistry were examined. Results Compared with mice in asthma and pcDNA3. 1 group, mice in vaccine group showed significantly reduced airway inflammation (P＜0. 05) and AHR (P＜0. 05). IFN-γ content in BALF were increased in mice from vaccine group compared with the asthma group and the pcDNA3. 1 group ( P ＜0. 05) , and IL-13 content in BALF were decreased. Conclusion HSF70/CD80 DNA vaccine can reduce airway inflammation and hyperresponsiveness in asthmatic mouse and this chimerical plasmid could be a candidate vaccine to prevent asthma.

Objective To explore the surgical treatment of Crohn's disease(CD).Methods Clinical data of 11 patients with Crohn's disease undergoing surgery were retrospectively analyzed.Results 9 cases were diagnosed before operation,with symptoms including abdomen pain,diarrhea or constipation,weight loss,and segmental lesions.Abdominal mass was the most common cause,accounting for 54.5%(6/11)in surgery,and intestinal obstruction was secondary.accounting for 36.4%(4/11),and perianal abscess,9.1%(1/11).Partial enterectomy and anastomosis was the main procedure.3 cases were suspected malignance and underging radical cure.The pathology results showed there was moderate atypical hyperplasia in 2 of 3.Most of the patients had a good recovery and their nutritional conditions were improved obviously(P＜0.05).Conclusion Abdominal mass and intestinal obstruction are the main causes of surgical management in patients with Crohn's disease.The possibility of cancerization is higher in patients with longer medical history.The length of intestine reseeted would be enough with visitable lesions resected,and the operative effects are as good as those underwent radical cure.
