Objective: To study the effect and mechanism of Rhodobryum giganteum (Schwaegr.) Par. 's anti-atherosclerotic effect. Methods:Vascular endothelial ceils were cultivated and the H2O2 were used to induce the oxidative stress injury of human umbilical vascular endothelial cells (HUVEC). Water extract of Rhodobryum giganteum (Schwaegr.) Par. Was added to cultivated HUVEC, and the activity of the cells was carefully determined by OD value with MTF method. The Griess Reagent was used to detect the NO concentration of different groups. At the same time, the NO fluorescence analysis probe, DAF-FM DA. (3-amino, 4-aminomethyl-2', 7'-difluorescein, diacetate), was used to determine the activity of NO synthase. Results:The most suitable stimulating concentration of H2O2 on HUVEC is 12.5 mmol· L-1. Water extract of Rhodobryum giganteum (Schwaegr.) Par. Was co-cultured with HUVEC damaged byH2O2 .The OD values indicate that 3.33,2.50 mg· mL-1 water extract groups increase activity of the cells significantly compared with the model group (P <0.05) ,and 3.33 mg·mL-1 is much better than 2.50 mg·mL-1 dose group. To determine the content of NO and NOS, the 2.50 mg·mL-1 dose has significant effect (P < 0.05). Conclusions: The H2O2 concentration of 12.5 mmol· L-1 could be used to establish the injured model of endothelial cell successfully. 2.50 and 3.33 mg·mL-1 water extract of Rhodobryum giganteum (Schwaegr.) Par. Have protective effect on ECV304 injured by H2O2. 2.50 mg· mL-1 water extract of Rhodobryurn giganteum (Schw aegr.) Par could increase the activity of NOS and promote the synthesis and secretion of NO.

Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.

Objective To study the effect of red cell and plasma protein parameters on progression, prognosis and recurrence of cerebral infarction. Methods Clinical data from 105 patients with cerebral infarction were analyzed. The pa?tients were divided into four paired groups:progressive stroke group and complete stroke group, short-term favorable progno?sis group and short-term unfavorable prognosis group, long-term favorable prognosis group and long-term unfavorable prog?nosis group, relapsed cerebral infarction group and not relapsed group by different criterion. The red cell and plasma protein parameters were compared between groups. Results There were significantly higher mean corpuscular volume(fL:85.92± 4.50 vs 83.79±4.64,t=2.164,P<0.05), red cell distribution width(fL:13.50±2.45 vs 11.90±2.90,t=2.694,P<0.01), globu?lin(g/L:27.46±4.33 vs 24.79±4.03,t=3.029,P<0.01)and lower albumin(g/L:39.00±3.86 vs 42.89±4.45,t=4.242,P<0.01)in progressive stroke group than those of complete stroke group. The elevated red cell distribution width, reduced albu?min were the risk factors of progressive stroke. In the short-term unfavorable prognosis group, red cell distribution width was significantly higher than that in short-term favorable prognosis group(fL:13.90 ± 2.45 vs 12.00 ± 2.12,t=2.905,P<0.01). The red cell distribution width was positively correlated with mRS scores assessed 3 months and 18 months after cerebral in?farction(P<0.01). Conclusion Progressive stroke rate increases in cerebral infarction patients with elevated red cell distri?bution and reduced albumin;Red cell distribution width has a certain reference value for forecasting the prognosis of cere?bral infarction .

Objective To study the distribution of Candida infection and drug tolerance in intensive care unit(ICU). Methods A retrospective study was conducted. The critical patients admitted from January 2011 to December 2013 in ICU of the First Hospital of Jiaxing in Zhejiang Province were enrolled,and their clinical data with positive Candida culture and drug susceptibility results in specimens of sputum,urine,blood,ascites,bile, etc were collected. In the study of these 3 years in ICU,the situation of Candida infection,the distribution of positive specimen,the condition of distribution of different strains of Candida,and the Candida tolerance to antifungal drugs were analyzed. Results From 2011 to 2013,2 412 times of patients(including one patient had admitted into ICU for more than one time)were admitted into ICU in which 407 cases were of Candida infection(16.9%),and the rate of Candida infection was rising gradually in the 3 years〔2011 to 2013 Candida positive rates were 13.4%(77/573), 16.1%(146/907),19.7%(184/932)〕,the difference being statistically significant(P<0.01). In the 407 strains of Candida,166 strains(40.8%)were isolated from sputum,157(38.6%)from urine,53 strains(13.0%)ascites, 13 strains(3.1%)blood,11 strains(2.7%)bile,7 strains(1.7%)from other specimens. The strain distribution of Candida was mainly as follows:Candida albicans(174 strains),Candida glabrata(131 strains),Candida tropicalis (83 strains),Candida parapailosis(5 strains),Candida krusei(12 strains),and 2 strains of rare Candida portugal and Lipolztica. From 2011 to 2013,the highest tolerance of Candida albicans,Candida glabrata,Candida tropicalis to fluconazole,itraconazole,Fushita Yasu and other antifungal drugs was in 2013,and the lowest was in 2012,the rates of tolerance of the above 3 strains of Candida to amphotericin B being 0,to itraconazole being the highest(10.9%, 27.8%,9.6%,respectively),to Fushita Yasu the secondary(6.6%,11.0%,0,respectively)and to fluconazole the last(4.7%,7.4%,1.9%,respectively),and the rates of tolerance of Candida parapsilosis,Candida krusei,Candida Portugal,Candida lipolztica to amphotericin B,fluconazole,itraconazole,Fushita Yasu were all 0. Conclusion In ICU,the Candida infection is mainly in the respiratory tract and urinary tract,its rate of infection has a tendency of rising,and the rate of Candida tolerance to itraconazole is the highest.

This study was aimed to establish a method for the rapid content determination of Ixerin Z and 11,13α-dihydroixerin Z in Ku-Die-Zi (KDZ) injection by UPLC-ESI-MS/MS. The separation was performed on a Waters ACQUITY BEH C18 column (2.1 mm × 50 mm, 1.7μm) by using a gradient elution with the mobile phase of acetonitrile-water at the flow rate of 0.4 mL·min-1. The column temperature was set at 40℃. Multi-reaction moni-toring (MRM) scanning was employed for quantification in ESI negative mode. The results showed that two sesquit-erpene lactones in KDZ injection were totally separated within 2 min. The linear range of Ixerin Z was 5.70-182.50 ng·mL-1, and the linear range of 11,13α-dihydroixerin Z was 4.60-131.25 ng·mL-1. The correlation coefficient r was more than 0.999 0. The recovery rates (n = 6) were 98.18% and 97.52%, with RSDs < 1.5%. The established method was successfully applied for simultaneous content determination of Ixerin Z and 11,13α-dihydroixerin Z in 6 batches of KDZ injection from 2 factories, which had some variations on the content determination results. It was concluded that the method was rapid, accurate and sensitive, which can be used for the content determination of two sesquiterpene lactones in KDZ injection.
