The peripheral renous blood which were taken from healthy volunteers and platelet was isolated. Platelet samples were randomly divided into six groups. The effects of different concentration of taurine( Tau) on benzo py-rene( BAP) induced platelet aggregation in vitro activation function were investigated by detecting the maximum platelet aggregation rate, the positive expression rates of platelet membrane surface CD62P and PAC-1. The results showed that platelet maximum aggregation rate had significant differences between each concentration of BAP-Tau groups and solvent control group in adenosine diphosphate(ADP) and collagen induced (P<0. 01). The positive expression rates of platelet membrane surface CD62 P and PAC-1 in BAP-Tau high concentration group had signifi-cant differences compared with solvent control group ( P<0. 01 ) . Different concentration of Tau could antagonize platelet function damage induced by BAP with a concentration gradient change.

0 05). The median duration of survival was 8 5 months, and 1 year survival rate was 32 2%. Toxicity was chiefly hematologic in the form of neutropenia. The major non hematologic toxicity was nausea or vomiting. Conclusion The GP combination chemotherapy is an active regimen for the advanced NSCLC with tolerable toxicity.

Objective To evaluate the effectiveness of video-assisted thoracoscopic surgery (VATS) for metastatic lung tumors. Methods Clinical records of 31 cases of metastatic lung tumors treated by VATS were retrospectively analyzed. There were 2 cases of lobectomy, 1 case of lobectomy and metastasectomy, 1 case of lobectomy and resection of metastatic tumor in the chest wall, 2 cases of segmentectomy, 20 cases of wedge resection, and 5 cases of wedge resection and metastasectomy. Results No fatal cases were observed. Postoperative complications, including 1 case of respiratory insufficiency, 2 cases of pulmonary infection, 2 cases of continuous alveolar leakage and 3 cases of pleural effusion, were cured by antibiotic therapy and closed thoracic drainage. One case of lung metastasis from primary liver cancer was found lumbar vertebral metastasis at 2 months after operation and was referred to the Department of Orthopedics for further treatment. The 1- and 3-year survival rates were 71.0% (22/31) and 38.7% (12/31), respectively. Conclusions Video-assisted thoracoscopic surgery is a feasible and safe treatment for metastatic lung tumors with surgical indications.

AIM: Two models of experimental myocardial ischemia were set up to observe the protection of Danshen glucose injection against ischemia in rats. METHODS: Models of experimental acute myocardial ischemia were made by ligature or medication (pituitrin) to check the indices of ECG, hemodynamics, and morphology. RESULTS: A dosage of Danshen glucose injection 4.0 g/kg, 8.0 g/kg was given to rats by intravenous injection; the rats had undergone a thirty-minute ligatute of coronary left anterior descending branch, and used as a model of ischemic reperfusion. The observations showed that Danshen glucose injection exerted a recovery effect on heart rate, blood pressure, internal pressure of left ventricule and its peak/trough rate (?dp/dt max ), and ST segment (electrocardiogram). The injection markedly reduced the myocardial infarct size of the coronary-ligatured rats. The injection benefited the rats with pituitrin (iv) induced acute myocardial ischemia to reverse and T-wave fall. CONCLUSION: Danshen glucose injection has a protective and therapeutic action on the experimental myocardial ischemia of rats.

AIM: To establish a HPLC digitized fingerprints of Panax Ginseng rubra to control its quality. METHODS: The chromatographic fingerprints were determined by injecting 20 ?L of the sample solution each time on a Century SIL C_ 18 AQ column (20 cm?4.6 mm, 5 ?m) with the gradient elution solvent system composed of 0.1 mol/L NaH_2PO_4 aqueous solution-acetonitrile. The flow rate was 1 mL/min, the column temperature was maintained at (30?0.15)℃ and the signals were acquired at 203 nm. The chromatographic fingerprints were evaluated by both the chromatographic fingerprint index (F) and the information index of chromatographic fingerprint (I) and so on. RESULTS: 30 co-possessing peaks were selected as the fingerprint peaks and the similarities between each of the ten batches and the referential chromatographic fingerprints of Panax Ginseng rubra were calculated while taking adenosine peak as the reference peak. CONCLUSION: This method with good characteristics and specificity can be used in the quality control of Panax Ginseng rubra.

Objective To study the glutamine combined with early enteral nutrition’s effects on severe acute pancreatitis’systemic inlfammation. Methods 150 Cases with severe acute pancreatitis were divided into total parenteral nutrtion group(TPN group), early enteral nutrition group(EEN group) and Glutamine and early enteral nutrition group(G+EEN group) according to their therapeutic methods. The curative effects, APACHEⅡscore and liver and kidney function were compared after treatment. Inlfammatory cytokines of hs-CRP, TNF-α, IL-1β, IL-6, IL-8 and IL-10 before and after treatment were detected and compared. Results The efifciency rate in G+EEN group was signiifcantly better than that in TPN and EEN group(P<0.05), with lower APACHEⅡscore and better liver and kidney function. The level of hs-CRP, TNF-α, IL-1β, II-6 and IL-8 after treatment in G+EEN group were signiifcantly lower than that in TPN and EEN group(P<0.05), except IL-10, which was signiifcantly higher than that in TPN and EEN group (P<0.05). Conclusion Glutamine combined with early enteral nutrition could signiifcantly ameliorate severe acute pancreatitis’systemic inlfammation, its curative effects is better than early enteral nutrition and total parenteral nutrition.

Objective To study the clinical and neuroimaging features of subtypes of multiple system atrophy (MSA) and their correlations. Methods One hundred and forty-three MSA cases fulfilled Gilman diagnostic criteria (1999) were recruited and their clinical subtypes and stages were classified. Using the staging methods of the pontine cross sign and putaminal slit proposed by Horimoto, 108 patients showed abnormalities in MRI and were further evaluated. The relationship between the subtypes of MSA, disease duration, and MRI abnormalities has been analyzed. Results Of 143 MSA patients, the male-to-female ratio is 1.3:1 ; 93 cases are diagnosed with MSA-C, 39 with MSA-P, and 11 with MSA-P + C; 90 cases with probable diagnosis, and 53 with possible diagnosis. Of the 76 MSA-C cases with MRI abnormalities, 36 (47%) show the pontine cross sign and 10 (13%) show the putaminal slit; of the 24 MSA-P cases with MRI abnormalities, 6 (25%) show the pontine cross sign and 6 (25%) show theputaminal slit. In addition, MSA-C cases with shorter disease duration demonstrate earlier stages of the pontine cross sign. Conclusions In this study, the number of MSA-C cases is more than MSA-P, which might be related to the ethnic background. In neuroimaging, both the pontine cross sign and the putaminal slit are the marked features of MSA. To some degree, the subtypes of MSA are related with the features of imaging, that is, MSA-C patients present the pontine cross sign more often than MSA-P, and the putaminal slit is a comparatively common feature among MSA-P cases.

Objective To study the correlation between clinical rating scale and the duration of multiple system atrophy.Methods One hundred and twenty-two MSA cases fulfilling Gilman diagnostic criteria were recruited.Unified Multiple System Atrophy Rating Scale(UMSARS)was applied to assess the degree of the patients' disability.For analyzing the correlation between the UMSARS scores and the duration of the disease,the Spearman's rank correlation coefficients were calculated.Results Among 122 MSA cases,male:female ratio was 1.7:1;disease duration lasted(2.8±1.6)years:possible MSA accounted for 50 cases(41%),probable MSA 72 cases(59%);MSA-P 35 cases(29%);MSA-C 73 cases(60%).MSA-P+C 5 cases(4%),MSA-A 9 cases(7%).The scores of UMSARS,UMSARS-Ⅰ and UMSARS-Ⅱ were found positively correlating with the disease duration.The Spearman's rank correlation coefficients were 0.368,0.266 and 0.392 respectively,all P<0.01;the adjusted Spearman's rank correlation coefficients were 0.360,0.257 and 0.385 respectively.all P<0.01.Conclusions MSA has complex clinical manifestations.which should include MSA-P+C subtype.UMSARS is a reliable scale to mirror the progression of MSA.which is useful to study the clinical features and disease duration of MSA.
