Objective To investigate the relationship between carotid atherosclerosis(CAS)plaque and its related factors and cerebral infarction(CI).Methods The 91 patients with CI were detected by Color Doppler and the levels of plasma lipid,blood glucose(BG)and fibrinogen(Fbg)were evaluated,and compared with normal control(NC)group.Results(1)Compare with NC group,the IMT,prevalence of CAS plaque,the rates of soft plaque in CI group were significantly higher(all P

Objective To investigate the usefulness of apparent diffusion coefficient (ADC)value and its coefficient variance (CV) in differentiating the cerebellopontine angle tumors.Methods 5 1 cases of cerebellopontine angle tumors comfirmed by surgery were enrolled ,in which cerebral enhanced MRI were obtained MRI data of different type of tumors were analyzed.ADC value and its CV of tumors were calculated.Results There were 24 cases of schwannoma,14 cases meningioma,7 cases metastases,4 cases epider-moid cyst and 2 cases dermoid cyst.There were obvious differences on ADC value’s CV among the schwannoma,meningioma and metastases (t=-1.31,P =0.03;t=-0.56,P =0.04;t =0.07,P =0.04).ADC value of schwannoma was only significant higher than that of meningioma (t=-2.5,P =0.04).Conclusion In combination with MRI,ADC value and its CV have a higher value in differential diagnosis of cerebellopontine angle tumors.

Objective To study the validity of furosemide test for predicting the hematoma enlargement in pa- tients with hypertensive cerebral hemorrhage.Methods Four hundred fifty-one patients with hypertensive cerebral hemorrhage were diagnosed using CT after oneset of the disease and 24 h reexamined 24 h after.The incidence of enlarged hematoma was evaluated by comparison the baseline and 24 h CT scanning.Furosemide(20 mg iv)was ad- ministered and blood pressure was measured 30 min after furosemide.Results The decreasing level of MAP after furosemide was significantly inversely related with incidence rate of hematoma enlargement{ r=-0.94,t=58.4,P 10 mmHg as the cut-off point,with the rate of hematoma enlargement as being 6.4 %,MAP decreased≤10 mmHg was associated with increases in prevalence of hematome to 33.2 %(?~2=51.82, P

Objective To compare the results of surgical treatment of cardiac carcinoma through left thoracic approach and abdominal approach.Methods After finished cardiac carcinoma resection and gastroesophagus anastomosis in thorax through left thoracic approach,standard D2 regional lymph nodes dissection or/and combined pancreas and spleen resection were performed immediately through abdominal approach in 19 patients.Two surgical specimens were examined individually.Results 122 lymph nodes were founded in the abdominal surgical specimens,in which 23 were metastasis lymph nodes founded in 7 patients (7/19,37 %).Conclusion Left thoracotomy alone can no achieve complete resection for advanced gastric cardiac carcinoma.It should be treated through the combined abdominal and thoracic approach.

Objective To discuss the quantitative diagnosis of stagnation of Qi and blood stasis syndrome in chronic prostatitis. To make diagnosis chart and ensure diagnosis threshold level which provide statistics evidence for syndrome differentiation of TCM. Methods By the statistical ways, 168 cases of chronic prostatitis belong to stagnation of Qi blood and stasis syndrome and 198 cases of non-stagnation of Qi and blood stasis syndrome were investigated. To make a diagnosis chart and ensure diagnosis threshold level by applying the method of the maximum likelihood discriminatory analysis. Results The quantitative diagnosis chart was made and diagnosis threshold level was 26. According to the retrospective and prospective test, its sensitivity, especially degree, coincidence rate, error rate and positive likelihood ratio were 94.64%, 88.89%, 91.53%, 8.47%, 8.52 and 94.28%, 90.32%, 92.42%, 7.58%, 9.74. Conclusion The indexes of the quantitative diagnosis have good objectivity. According to the retrospective and prospective test, the diagnosis chart was proved to be practical.

0.05).It could also decrease the times of wet manure induced by folia sennae,while it was of no effect on diarrhea induced by castor oil. CONCLUSION: Volatile oil from A.longiligulare T.L.Wu has anti-inflammation,analgesic and anti-diarrhea effect related to the cure for ulcerative colitis.

AIM: To investigate antioxidative and antinitrosative effects of volatile oil from A.longiligulare T.L.Wu on dextran sulfate sodium(DSS)-induced ulcerative colitis mice. METHODS: Balb/c mice were fed with 4% DSS solution for 7 d to induce ulcerative colitis.Using biochemical method,the activity of antioxidative enzyme SOD,MDA and NO were determined in normal,model,SASP and three mouse's groups with low,moderate and high volatile oil from A.longiligulare T.L.Wu respectively.At the same time,the activity of iNOS was also measured by immunohistopathology. RESULTS: The concentration of MDA and NO were reduced and SOD increased significantly in high-and moderate-volatile oil groups compared with those in the model group.The activity of iNOS was reduced significantly in high-and moderate-volatile oil groups compared with those in the model group.The results demonstrated that the expression of iNOS was significantly inhibited in DSSinduced ulcerative colitis mice after being treated with high or moderate-dosage volatile oil. CONCLUSION: Volatile oil from A.longiligulare T.L.Wu has antioxidative and antinitrosative effects which may be one of the mechanism for treating UC.

Background Many studies and clinical trials of pharmacologic vitreolysis are already under way to try to improve vitreo-retinal surgery and to liquefy and detach the vitreous from the retina ultimately, including chondroitinase,hyaluronidase,dispase and plasmin. However, there has not been any report on purification of human plasminogen from cord blood plasma and inducing posterior vitreous detachment of the animal eye at present.Objective This study was designed to isolate and purify the production of human plasminogen (Plg) from cord blood plasma with ethanol precipitation and evaluate the efficacy of Plg in inducing posterior vitreous detachment (PVD).Methods Human Plg was Separated and purified from cord blood plasma by ethanol precipitation method. The protein band corresponding to Plg with molecular mass of 92 000 was revealed in SDS-PAGE and confirmed by MALDI-TOF and Mascot database. Anion-exchange chromatography and plasminogen activity assay kit were used to obtain purified Plg with biological activity. Twenty-five fresh pig eyes were enucleated and assigned to 5 groups and 5 eyes for each group. The normal eyes were used as control group. Balanced salt solution(BSS)of 0.1 ml was intravitreally group and standard substance group. All of the eyes were then incubatedfor 60 minutes under the 37 ℃. Retinal histopathology and ultrastructure were examined under the light microscopy, scanning electron microscopy ( SEM ) and transmission electron microscopy (TEM). Results The Plg with potential fibrinolytic activity was successfully extracted and purified from cord blood plasma by ethanol precipitation method. No posterior vitreous detachment (PVD) was seen in normal control group, BSS group and r-SK group following the intravitreal injection under the sem. However,PVD was demonstrated in r-SK+ Plg group and standard substance group under the SEM. The inner limiting membrane ( ILM ) and the retina were well preserved in all of the experimental eyes. No retinal morphology and ultrastructural abnormality were found under the light and SEM and TEM. Conclusion Ethanol precipitation is a feasible way to isolate and purify Plg from human cord blood plasma. Extracted Plg shows potential fibrinolytic intravitreal injection of Plg.
