ABSTRACT
OBJECTIVE:To establish GC-MS fingerprints of liposoluble constituents from Danqi soft capsule. METHODS:GC-MS method was adopted. GC chromatogram column was DB-5 ms capillary column with high purity helium (99.999%)as carrier gas at the flow rate of 1.0 mL/min,with temperature programming. The injector temperature was 250 ℃. The sample size was 1 μL. The shunt ratio was 1:40,with distributary injection. Ionization mode was as follows as electron bombardment ion source,ion source temperature of 280 ℃,injector temperature of 300 ℃,electronic energy of 70 eV, solvent delay time of 3 min,mass charge ratio(m/z)of 50-550. Using ethyl palmitate as reference,MS spectrums of 11 batches of samples were determined. Similarity evaluation was conducted by using TCM Fingerprint Chromatogram Similarity Evaluation System(2004 A edition)to determine common peak. The common peaks were determined by LC Solution 2 workstation standard mass spectrometry Library(NIST05.LIB or NIST05s.LIB). RESULTS:The similarity of 11 batches of samples was higher than 0.90. After validation,GC-MS chromatograms of 11 batches of samples were in good agreement with control fingerprint. There were 49 common peaks in GC-MS chromatogram,and 38 chemical constituents were identified, accounting for 94.94% of total peak areas. CONCLUSIONS:Established fingerprint can provide evidence for quality evaluation of Danqi soft capsule.
ABSTRACT
Objective To investigate the relation between Fas-mediated apoptosis and glucocorticoid treatment in myasthenia gravis (MG). Methods In 17 patients with MG, 6 patients received glucocorticoid treatment (glucocorticoid treatment group),and 11 patients were treated without glucocorticoid (nonglucocorticoid treatment group). Meanwhile, 13 healthy cases were selected as healthy control group. CD4,CD8 and Fas expressions in peripheral blood T lymphocyte were detected by flow cytometry in three groups and analyzed. Results The percentage of CD4-CD8+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group was significantly higher than that in healthy control group[(36.75 ± 11.56)% vs. (26.31 ±9.00)%, P = 0.027], while the percentage of CD4-CD8- cells was significantly lower [(30.56 ± 9.72)% vs.(42.96 ± 11.54)%, P =0.018]. The percentage of CD4-CD8+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group was significantly higher than that in non-glucocorticoid treatment group [(36.75 ± 11.56)% vs. (25.24 ±7.63)% ,P =0.019]. The percentages of Fas+ and CD8 +Fas+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group were significantly higher than those in healthy control group[(46.10 ± 7.13)% vs. (31.22 ± 13.00)%, P=0.006; (62.86 ± 12.29)% vs. (45.59 ±11.50)%, P = 0.003]. The percentage of CD8+ Fas+ cells in peripheral blood T lymphocyte in glucocorticoid treatment group was significantly higher than that in non-glucocorticoid treatment group [(62.86 ± 12.29)%vs (50.84 ± 8.31 )%, P = 0.034]. Conclusions Glucocorticoid treatment may have influence on peripheral blood T lymphocyte subsets in patients with MG. Fas-mediated apoptosis may be involved in the mechanism of glucocorticoid treatment in MG.
ABSTRACT
<p><b>OBJECTIVE</b>To observe the clinical effect and the influences of Shuxuetong injection on serum neuron-specific enolase (NSE) level, the neurological deficit and activities of daily living in patients with acute cerebral infarction.</p><p><b>METHOD</b>The 80 patients with acute cerebral infarction were randomly divided into Shuxuetong treatment group (40 cases) and routine control group (40 cases), both received routine treatment, while Shuxuetong injection was given additionally to treatment group. The serum NSE level, the National Insitute of Health Stroke Scale (NIHSS) scores and the clinical effect were observed pre-and post-treatment. The Barthel Index (BI) was evaluated after one month.</p><p><b>RESULT</b>The serum NSE level and NIHSS scores in two groups of post-treatment decreased obviously than those of pre-treatment, and after treatment in Shuxuetong treatment group the serum NSE level and NIHSS scores were significantly lower than those in control group, the differences were significant (P<0.05). Effective rate of Shuxuetong treatment group was 87.5%, and control group was 65%, the difference of the clinical effect between the two groups was significance (P<0.05). After one month BI of post-treatment in two groups improved than those of pre-treatment, and Shuxuetong treatment group was significantly better compared with control group (P<0.05).</p><p><b>CONCLUSION</b>Shuxuetong injection has the remarkable neuronal protective effect, can decrease the serum level of NSE after acute cerebral infarction, promote recovery of nerve function, reduce disability rate, and improve quality of life and prognosis of patients with acute cerebral infarction.</p>

Objective To evaluate the relationship between post-stroke urinary incontinence(UI)and 1 year stroke outcomes.Methods One hundred and thirty consecutive cerebral stroke survivors were classified into 2 groups according to their incontinence status at 1 to 10 d after onset.The patients'baseline characteristics,1 year mortality rate,abilities in the activities of daily living(ADL)and Modified Rankin Scale(mRS)scores were compared.Multivariate analysis was applied to highlight UI risk factors and correlations between UI and 1 year outcomes.Results Total anterior circulation syndrome(TACS)numbers and National Institutes of Health stroke assessment (NIHSS)scores in the UI group exceeded significantly those in the non-UI group,and both were significantly associated with initial UI.The 1 year mortality rate,patients'ADL dependence and mRS scores in the UI group exceeded those in the non-UI group significantly.Initial UI was also significantly associated with the 1 year outcome independently,as well as with age＞75 years,Oxfordshire Community Stroke Project(OCSP)classification and initial NIHSS score.Conclusion UI is common in the patients with TACS and higher initial NIHSS scores.Initial UI predicts a poor 1 year outcome,SO treatment should be strengthened.
ABSTRACT
Objective To study the expression of eytokines in acute hemorrhage patients with systenlic in-flammatory response syndrome(SIRS)and multiple organ dysfunction syndrome(MODS).Methods Platelet acti-vation markers CD62p and cytokines in acute hemorrhage patients with SIRS and MODS were detected by using flow cytometry,and compared with that of control group.Results The expression of CD62p and cytokines(TNF-α and IL-6)in acute hemorrhage patients,with or without SIRS and MODS wag significantly higher than that in control group(P<0.01),and higher in MODS group than in SIRS group,and in MODS death group than in MODS survival group(P<0.01).Conclusion The activation of platelet and the over-expression of cytokines participate in the on-set and development of acute hemorrhage,SIRS and MODS,and were related with the severity of disease and progno-sis.
