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 describe the Evidence-based Nursing Competences of nurses who have received Evidence-based Nursing training in tertiary hospitals in Shanghai and analyze its influencing factors. Methods Use the Evidence-based Nursing Competency Rating Scale made by Wang Yilei to investigate 428 nurses who have received Evidence-based Nursing training in 9 tertiary hospitals in Shanghai. Results The average score was (54.39±16.77), the 3-scoring rate was 25.1%-64.3%and the 4-scoring rate was 2.8%-23.1%which indicates the nurses had moderate-low level of EBNP competence after training project including in service training, seminar, lecture, workshop and so on, but still at a low level. Educational background and training time were the main influencing factors (P<0.05). Conclusions Nurses in tertiary hospitals in Shanghai have a moderate-low level of evidence-based nursing practice competence after education project. Comprehensive evidence-based nursing training system is expected.

Objective To investigate the effects of 1,25-dihydroxyvitamin D3 in the prevention of corneal allograft rejection. Methods Forty-five SD rats (only right eyes) were used as recipients,and 15 Wistar rats (double eyes) were used as donors. SD rats were randomly divided into 3 groups: the autograft control group,the allograft control group (receiving peanut oil as placebo),and the allograft group were treated with 1,25-dihydroxyvitamin D3 (1.0 ?g.kg-1.d-1,3 times/d for 13 d,i.p.). Drugs were injected intraperitoneally for 14 d after transplantation. Routine antibiotic eye drops were used. Grafts were observed by operating microscopy everyday after transplantation. Five SD rats in each group were killed respectively at the 14,21,and 30 d postoperatively. Neovascularization and inflammation were evaluated with HE staining. ELISA was used to detect the contents of IL-1?,IL-2,IL-8,and IL-10 in the peripheral blood. Results The mean survival time (MST) of the graft was (21.7?6.8) d in the autograft control group,(11.2?2.5) d in the allograft control group,and (19.3?5.2) d in the allograft group. There was statistically significance between the latter 2 groups (P

Objective To investigate the changes of protein C and fibrinolytic system in patients with acute cerebrovasculer disease and the influence of intervened treatments on acute cerebral infarction(ACI).Methods Determinations of protein C(PC),protein S (PS),thrombomodulin(TM),Tissue-type plasminogen activater(t-PA),plasminogen activator inhabitor(PAI) were performed in patiens with acute cerebrovasculer disease and normal control(NC),then redeterminated these items after treatments in patients with ACI.Results PC,PS:The levels in patients with ACI were significantly lower than that in other groups.After dreatments,the levels in patients with ACI increased.There were no significantly discrepancy in acute cerebral hemorrhage(ACH) and lacunar cerebral infarct(LCI) compared with NC;TM:The levels in patients with ACH,ACI were significantly higher than that with LCI and NC.After dreatments,the levels in patients with ACI decreased;t-PA:The levels in patients with ACI were lower than NC,whereas the levels in patients with ACH increased.After dreatments,the levels in patients with ACI increased;PAI:The levels in patients with ACI were significantly higher than NC,and also found that the levels in patients with ACH and LCH were higher compared with NC.The levels in patients with ACI decreased after dreatments.Conclusions There are obviously abnormalities in plasma coagulative and fibrinlytic parameters in acute cerebrovasculer disease;To check the levels of PC,PS,TM,t-PA,PAI are important to predict the type of stroke,the seriousness of disease,the effect of treatment,prognosis of the cases and suggest that earlier treatments be important.

Objective To observe the effects of Uremic Clearance Granule combined with angiotensin receptor blockers (ARB) or angiotensin converting enzyme inhibitors (ACEI) in treating different period of diabetic nephropathy (DN ) .Methods 46 patients with DN were divided into the control group and the treatment group ,23 cases in each group .The two groups were given the rou-tine hypoglycemic therapy .The control group was treated with ACEI or ARB ,while the treatment group was given Uremic Clear-ance Granule 5 g each time ,four times daily for successive 4 weeks .Then the indexes of serum creatinine ,blood urea nitrogen ,cysta-tin-C ,microalbumin and 24 h urine total protein at 24 h before and after treatment were observed .Results The microalbumin and 24 h urine total protein after treatment in the two groups were reduced compared with before treatment (P<0 .01) .In the patients with the stage Ⅲ of DN ,the urine protein decrease after treatment had no statistical difference between the two groups (P>0 .05) . In the patients with the stage Ⅳ of DN ,on the basis of ACEI or ARB adding Uremic Clearance Granule could significantly decrease the urine protein(P<0 .05) .Conclusion ACEI or ARB combined with Uremic Clearance Granule has definite effect for treating massive proteinuria of DN .

Objective To evaluate the effectiveness of music therapy on anxiety and adverse reactions induced by chemotherapy in breast cancer patients after modified radical mastectomy. Methods One hundred and ten breast cancer patients were divided into intervention group and control group. The patients in the intervention group received music therapy,progressive muscle relaxation and guided inner image in addition routine nursing care. State Anxiety Inventory and Rotterdam Symptom Checklist (RSCL) were administered before the 2nd chemo-cycle and before the 3rd chemo-cycle. Results There was trend of lower scores on the Rotterdam Symptom Checklist total score and the State Anxiety score in intervention group than in control group (P＜0.05). Conclusion Music relaxation therapy can alleviate chemotherapy related adverse reactions and anxious.Therefore,music relaxation therapy is a practical psychological behavioral intervention for the breast cancer patients during the chemotherapy after modified radical mastectomy.

Recently,paclitaxel has been used as a new agent on patients with advanced esophageal cancer,and several studies have demonstrated that paclitaxel and paclitaxel-based regimens have significant activity in patients with advanced esophageal cancer and showed highly response rates than the combination of 5-fluorouracil (5-Fu) and cisplatin.However,there have been some problems which need to be solved such as drug-resistance,side effect,and so forth.The new medicament form of paclitaxel can not only depress poison without anti-allergy but also raise medicament curative effect as well as the pharmacal concentration.Although most of the research on the new medicament form of paclitaxel are still limited in the stage of laboratory,it has possessed potential advance in the treatment of advanced esophageal cancer.

Volume overload or hidden lung congestion is emerging as a pervasive problem in end-stage renal disease (ESRD) patients on hemodialysis,which will lead to cardiovascular complications and impact the patients' life quality and survival time,so how to improve volume control in patients on hemodialysis is a urgent research hotspot.Recently,the ap plication of lung ultrasound for semi-quantitative assessment pulmonary congestion in patients on hemodialysis has received general concern.Lung ultrasound not only can detect excessive extravascular lung water in the early period of pulmonary congestion,but also can predict cardiac events and mortality in ESRD.Lung ultrasound is an effective,sensitive,real-time and non-invasive tool beside.The application and progresses of lung ultrasound in evaluation of pulmonary congestion in hemodialysis patients were reviewed in this article.
