Objective:To study the surface enhanced Raman scattering ( SERS) of safflower and identify safflower injections by SERS quickly and effectively. Methods:Through comparative analysis of the Raman spectroscopy of safflower injections and the corre-sponding control herbs, the rapid identification of safflower injections was realized. Results:The results showed that several character-istic peaks of safflower were enhanced obviously in SERS, which could be used to identify safflower injections. Conclusion:The meth-od is reliable, rapid, accurate and specific, which can be applied as a method to identify safflower and its injections.

Objective To compare the clinical features of myocardial infarction (MI) in young adults with and without diabetes. Methods A total of 94 young adults with MI were enrolled in this study and divided into two groups according to whether they had diabetes:diabetic group (DM) and Non diabetic group (NDM).The clinical features,angiographic results,risk factors and prognosis were compared between the two groups. Results The incidence of atypical chest pain (25.0% vs 7.6%),non-ST segment elevation myocardial infarction (50.0% vs 9.1%),ventricular wall motion abnormalities (78.6% vs 42.4%),double vessels (35.7% vs 21.2%),triple vessels (39.3% vs 3.1%) and the incidence of mortality(10.7% vs 1.5%)were all significantly higher in DM group than in NDM group (P<0.05 or P<0.01).The number of affected vessels and Gensini scores were (2.110±0.875) and (52.61±10.47) in DM group,and(1.140±0.677),(34.02±10.24) in NDM group.The between group difference was statistically significant (P<0.05).Multiple linear regression showed that HbA1c and smoking were the independent risk factors for Gensini score. Conclusion The clinical features of young adult patients with MI and diabetes are more complex,their coronary stenosis are more serious,and the prognosis is poor.Smoking and HbA1c are positively associated with Gensini scores.

ObjectiveIn order to confirm the relationship of pathogenic factors and clinical manifestation of cerebral palsy. Methods185 children were divided into the prematurity group(91 cases) and maturity group(94 cases). The μ-test was applied to analyze the incidence of clinical manifestation of 185 children with cerebral palsy for different pathogenic factors. ResultsThe sever symptoms occurred more frequently in prematurity group than in maturity group. ConclusionThe earlier the careful follow-up for children with prematurity was performed, the earlier the diagnosis and treatment of cerebral palsy were achiened.

Objective To establish the analytical methods for determining the contents of tannins in different vegetative organs of Abutilon indicum (L.) Sweet. Methods The content of tannins, expressed as gallic acid equivalents, was measured by using the phospho molybdenum tungstic acid-casein colorimetry. Results The good linearity between concentrations and absorbances of gallic acid was found in the range of 2～10 mg/L, the average recovery was 99.63% and RSD was 1.08%, the contents of tannins in leaves, stems and roots of Abutilon indicum (L.) Sweet were 0.34%, 0.16% and 0.27% respectively. Conclusion The proposed method is sensitive, precise, accurate and reproducible, and it is suitable for the determination of tannins in Abutilon indicum (L.) Sweet.

In recent years,traditional English teaching has been greatly affected by network platform.As SMMU has been trying to perfect the Online English Writing Course,the questionnaire completed by the students taking the course shows that the course designs have proved effective in the improvement of research-based learning.

Objective To assess whether mTOR was activated in peripheral T lymphocytes of acute coronary syndrome (ACS)patients and to investigate the relationship among mTOR,regulatory T cells and cytokins. Methods Patients with acute coronary syndrome (n=32) were selected in ACS group. Meanwhile, patients who complainted of chest pain but were proven to be normal in ECG and in coronary arteriography, were excluded as ACS patients but were diagnosed as Chest Pain Syndrome (CPS) and selected in CPS group (n=28). The expression levels of mTOR, phospho-p70S6KT389 (indicative of mTORC1 activity) and phospho-AKTS473(indicative of mTORC2 activity) were investigated in T cells, which were isolated from peripheral blood of patients in ACS group or CPS group, using Western blot. The proportion of CD4+CD25+Foxp3+Tregs over CD4+cells were evaluated by FACS. And T cell subset related cytokines such as IFN-γ, IL-4, IL-17 and TGF-β1 were exam?ined by ELISA. Then we investigated the relationship among mTOR,regulatory T cells and cytokins by Spearman analysis. Results mTOR and p-p70S6KT389 expression were significantly enhanced in ACS group as compared with those in patients from CPS group (P<0.01). Higher levels of IFN-γ, IL-17 but lower level of TGF-β1 cytokines as well as decreased propor?tion of Tregs were observed in ACS group than those in CPS group (P<0.05). There was no significant difference in the level of IL-4 and p-AKTS473 between the two groups (P>0.05). By correlation analysis, p-p70S6KT389 expression level positively correlated with IFN-γ, IL-17(rs=0.91,092,P<0.01)and negatively correlated with Tregs and TGF-β1(rs=-0.85,-0.80, re?spectively, P<0.01). Conclusion mTORC1 pathway was activated in peripheral T lymphocytes of ACS patients, and Tregs insufficiency and cytokins imbalance both contribute to the activation of mTORC1 pathway and pathological process of ACS.

Objective To observe the anti-tumor effect of ethaselen on transplanted liver cancer(H22)and Lewis lung cancer mice.Methods The transplanted liver cancer(H22)and Lewis lung cancer mice models were established.Each genus consisted of 60 mice,which were divided into control,CTX,and three ethaselen dose groups,respectively,with 12 mice in each.Intraperitoneal injection(ip.)of three dosages was performed once a day through the abdominal wall separately,from the second to the eighth day after cancer was transplanted.On the eleventh day,six mice in each group were killed to calculate the tumor inhibition ratio and observe the cell cycle by flow cytometry,and the others were observed for the life extension ratio.Results When ethaselen was given at the dosage of 25,12.5 and 6.3 mg/kg,the tumor inhibition ratio was 52.5%,43.6% and 30.2%,and the life extension ratio was 56.6%,38.7% and 14.2% in the transplanted liver cancer(H22)mice,respectively.The tumor inhibition ratio was 43.8%,29.6% and 18.9%,and the life extension ratio was 47.3%,17.9% and 6.3% in the transplanted Lewis lung cancer mice,respectively.Compared with that of the control,the apoptosis ratio was obviously increased in each group,and there was obviously induced S phase arrest in 25.0 mg/kg(P

Objective To evaluate the effects of reminfentanil combined with propofl on patients received video assisted thoracoscopic surgery. Methods 40 ASA Ⅰ～Ⅱ patients underwent video assisted thoracoscopic surgery were randomly divided into two groups. BP、HR before anesthesia induction(T0) ,tracheal induction(T1) ,tracheal induction instantly (T2), after five minutes of tracheal induction(T3) were observed; The time of breathing recovery withdrawl,and open eye,extubation and instantly of extubation,VAS;to record in the operation and adverse effect of postoperative nausea were analyzed. Results During tracheal induction, hemodynamic and respiratory variables of groupR less then group F(P ＜ 0. 05), after operation group R time of breathing recovery withdrawl, and open eye, extubation is short of group F(P ＜ 0. 05). Two groups was not appear to know in operation, postoperative nausea is not satistically significant. Conclusion General anesthesia by reminfentanil combined with Propofol on video assisted thoracscopic surgery was safe and feasible.

Objective: To study the mechanism of Tuina in the treatment of skeletal muscle injury. Methods: Rabbits were heavily beaten at gastrocnemius muscle to make acute contusion model and then treated respectively by early Tuina and routine Tuina. The number of satellite cells of skeletal muscles was observed. Results: The number of the satellite cells continued to grow in both groups, and it began to increase significantly 3-5 days after Tuina treatment. Early Tuina treatment produces larger number of satellite cells than routine Tuina treatment.Conclusion: Early Tuina treatment is helpful to the marked recovery of skeletal muscles by increasing the number of satellite cell.
