Objective:To establish a method for the determination of baicalin in Kang 601 mixture. Methods:An HPLC method was adopted. An Agilent Eclipse Plus-C18 column (250 mm × 4. 6 mm, 5 μm) was used at room temperature (25 ℃) and eluted by methanol-0. 1% phosphoric acid solution(48:52) with a flow rate of 0. 8 ml·min-1 . The detection wavelength was 280 nm and the injection volume was 20 μl. Results:A good linear relationship was obtained between the peak area and the concentration of baicalin within the range of 18. 897-188. 975 μg·ml-1(r=0. 999 9). The average recovery was 99. 86%(RSD=0. 32%, n=9). Conclu-sion:The established method is specific, accurate and reproducible, which can be used for the determination of baicalin in Kang 601 mixture.

Objective To compare the effectiveness and safety of raltitrexed and fluorouracil(FU)/leucovorin (LV) combined with oxaliplatin for advanced colorectal cancer. Methods Fifty patients with advanced colorectal cancer diagnosed by histopathology or cytology were randomly divided into two groups with 25 cases each by envelope, but 1 case lost. Patients in experimental group were treated with raltitrexed (3 mg/m2, ≥ 15 min intravenously) combined with oxaliplatin (130 mg/m2 on day 1 ), patients in control group were treated with FU/LV combined with oxaliplatin:LV 100 mg/m2 infusion (over 2 h, from day 1 to day 3 ) followed by FU (400 mg/m2 infusion in 2 h and 600 mg/m2 continuous infusion from day 1 to day 3 ),combined with oxaliplatin ( 130 mg/m2 on day 1 ), 3 weeks were as one cycle. Patients received 6 or less cycles until disease progressed or toxicity could not be tolerated. Results Effective rate was 37.50%(9/24)and 33.33%(8/24) in experimental group and control group respectively (P＞ 0.05). Disease control rate in experimental group was 83.33% (20/24) while in control group was 70.83% ( 17/24 ) (P ＞ 0.05 ). The median time of progression-free survival (PFS) in experimental group and control group was 11.0 months and 9.0 months respectively (95%CI 8.643-11.357,P =0.015). Main adverse effects were anorexia, vomiting, neutropenia, thrombopenia, anemia, neurotoxicity, fatigue, aminotransferase abnormality, and so on. There was no statistic difference between two groups in side effects(P ＞ 0.05). Conclusions Raltitrexed combined with oxaliplatin is an effective regimen for the advanced colorectal cancer. Compared with traditional FU-based regimen, it is more convenient. Patients will have less venous exposure time and hospital days.Effective rate and mean survival time are superior or not inferior in raltitrexed treatment to that of FU-based regimen. Raltitrexed combined with oxaliplatin is worthy to be recommended in treating colorectal cancer.

Objective To quantitatively assess the left ventricular systolic and diastolic function in the elderly patients with dilated cardiomyopathy (DCM) by using Doppler tissue imaging (DTI) and to explore its clinical value. Methods A total of 20 normal controls and 22 old patients with DCM were enrolled in the study. The left ventricular end-diastolic diameter (LVEDd), left atrial diameter (LAD) and left ventricle ejection fraction(LVEF) were obtained by routine echocardiogram. And the systolic and early diastolic peak velocity (Vs and Ve) were detected by quantitative tissue velocity imaging (QTVI) and the mean value was accounted. The systolic mitral valve displacements (MVD) in 6 sites were determined by tissue tracking technique and the mean value was calculated. Results The LVEDd and LAD were significantly higher in DCM group than in normal group [LVEDd: (67.56±10.27) mm vs. (43.36±4.20) mm; LAD: (49.91± 6.27) mm vs. (32.00+4.53) mm, t=10.229 and 10.359, both P<0.01]. And the LVEF, Vs and MVD were lower in DCM group than in normal group [LVEF: (26.50 ± 8.25)% vs. (64.00 + 4.72)%; Vs:(5.14+1.30) cm/s vs. (8.89+1.87) cm/s; MVD:4.82+1.85 vs. 10.23± 1.95, t=18.502, 7.716 and 8.143, all P< 0.01].The Vs and MVD were significantly positively correlated with LVEF (r=0.78 and 0.89, both P<0.01). Conclusions DTI can quantitatively assess global and regional left ventricular systolic and diastolic function of elderly patients with DCM, and provide the reliable information for the judgment of pathogenetic condition.

Objective To explore the role of CD4+CD25+CD127low/-regulatory T cells (Tregs) in the pathogenesis of psoriasis vulgaris(PV). Methods Flow cytometry analysis was used to detect the amount of Tregs in peripheral blood and ELISA to test the levels of IL-10 and TGF-β1 in blood serum; the suppressive function of Tregs on autologous CD4+CD25-T cells was determined by MTT method. Results No significant difference was found in the proportion of Tregs in PV patients and healthy controls(P>0.05). There was a diminished suppression of Tregs from patients on autologous CD4+CD25- responder T cell proliferation in PV patients when compared with that in controls (P < 0.01). The serum level of IL-10 in patients was lower than that in controls (P < 0.01) while that of TGF-β1 in PV patients was significantly higher than that in controls(P < 0.01). Conclusion Abnormal function of Tregs and low secretion of IL-10 in PV patients might be related to the pathogenesis of psoriasis.

Objective To explore the diagnosis,treatment and prognosis of primary gastric malignant (lymphoma)(PGML).Methods The diagnosis and treatment data of 21 cases of PGML admitted in our(hospital) during 8 years was retrospectively analyzed.The diagnostic methods included barium meal(examination),gastroscopy,B type ultrasonography,and CT scan.All patients underwent operative treatment and most of the patients received adjuvant chemotherapy.Results Upper abdominal pain,digestive tract bleeding,emaciation and abdominal mass were common clinical manifestations of PGML.The resectabilty rate of PGML was 90.5% while the 5-year survival rate was 57.1%.Conclusions The key to a satisfactory prognosis was early diagnosis,radical curative operation and combined treatment.

BACKGROUND: The purpose of triage is to identify patients needing immediate resuscitation, to assign patients to a pre-designed patient care area, and to initiate diagnostic/therapeutic measures as appropriate. This study aimed to use emergency severity index (ESI) in a pediatric emergency room. METHODS: From July 2006 to August 2010, a total of 21904 patients visited the International Department of Beijing Children's Hospital. The ESI was measured by nurses and physicians, and compared using SPSS. RESULTS: Nurses of the hospital took approximately 2 minutes for triage. The results of triage made by nurses were similar to those made by doctors for ESI in levels 1-3 patients. This finding indicated that the nurses are able to identify severe pediatric cases. CONCLUSION: In pediatric emergency rooms, ESI is a suitable tool for identifying severe cases and then immediate interventions can be performed accordingly.

Objective To compare the effects of different methods of general anesthesia on postoperative cognitive function in patients undergoing non-cardiac surgery.Methods One thousand ASA Ⅰ or Ⅱ patients,aged 18-60 years and undergoing non-cardiac surgery,were randomly divided into five groups (n=200 each):isoflurane + propofol + fentanyl group (group IPF),isoflurane + remifentanil group (group IR),sevoflurane + propofol + fentanyl group (group SPF),sevoflurane + remifentanil group (group SR),and propofol + remifentanil group (group PR).Two hundred patients receiving non-operative treatment served as control group (group C).In groups IPF and SPF,anesthesia was maintained with inhalation of 1.68％ isoflurane or 1.71％ sevoflurane,target controlled infusion (TCI) of propofol with the target plasma concentration of 2-5 μg/ml,and intermittent intravenous boluses of fentanyl.In groups IR,SR and PR,anesthesia was maintained with inhalation of 1.68％ isoflurane or 1.71 ％ sevoflurane,or TCI of propofol with the target plasma concentration of 2-5 μg/ml,and TCI of remifentanil with the target plasma concentration of 2-6 ng/ml.The patients' cognitive function was assessed with minimental state examination (MMSE) 1 day before operation,when leaving the post-anesthetic care unit (PACU),and 1 and 3 days after operation,respectively.Z score was used to identify the cognitive dysfunction as recommended by Moiler when leaving the PACU,and 1 and 3 days after operation.Results Compared with group C,the MMSE score was significantly decreased when leaving the PACU,and the incidence of cognitive dysfunction increased when leaving the PACU and 1 day after operation in the other groups (P ＜ 0.05).Compared with groups IPF,IR,SPF and PR,the incidence of cognitive dysfunction was significantly increased in group SR (P＜0.05).Conclusion General anesthesia with sevoflurane combined remifentanil exerts fewer effects on the postoperative cognitive function in patients undergoing non-cardiac surgery.
