2016.0 ng/L group (n=85) and followed up for average 371 days (90-540 d).Cardiac death or decompensated heart failure(HF) readmission were counted as advease events end-point for the purpose of this analysis.Results At follow up,76 patients had the cardiac events (26 patients died from cardiovascular causes and 50 patients being rehospitalization).No differences in admission NT-proBNP between patients with and without cardiovascular events.However,patients with high pre-discharge NT-proBNP(3872.0 vs 1306.0 ng/L,P

Objective To establish the determination method of baicalin in the children's YifeiPingchuan mixture by RP-HPLC.Methods A Kromasil C18 column was used with methanol-(0.4%)phosphoric acid-triethylamine (45 ∶ 55 ∶ 2 drops) as mobile phase with a column temperature of 28 ℃.The flow rate was 1.0 ml/min.The detection wavelength was set at 277 nm.Results The linear range of baicalin was 0.040~1.000 μg (r=0.9999) with a average recovery of 99.82 and RSD of 1.01%.Conclusion The method for quantification of baicalin was sensitive,accurate,and convenient,which can also be used as one of basis of quality standard for Yifei-Pingchuan mixture.

Objective To explore the histopathological features of 850 patients with esophageal malignant tumor in 10 years.Methods From January 2002 to January 2012, 850 patients diagnosed with esophageal malignant tumor were enrolled.Tumor location, general type, pathological type and TNM stage were retrospectively analyzed.All the data were described as case number and percentage.Results Among the 850 cases of esophageal malignant tumor, 33 lesions (3.9%) located in the neck segment of esophagus, 119 lesions (14.0%) located in the upper segment, 44 lesions (5.2 %) located in the upper-middle segment, 409 lesions (48.1%) located in the middle segment, 123 lesions (14.5 %) located in the middle-lower segment, 122 lesions (14.4%) located in the lower segment.Among the 724 eases clearly diagnosed as esophageal malignant tumor by general type, the most cases were ulcer type (305 cases, 42.1%), followed by medulla type (260 cases, 35.9%), fungating type (80 cases, 11.0%) and constrictive type (70 cases, 9.7%), and the least cases were intraluminal type (nine cases, 1.2%).Among the 850 cases of esophageal malignant tumor, squamous cell carcinoma (794 cases, 93.4 %) was the most common cytological type, followed by small cell carcinoma (19 eases, 2.2%), and the least common cytological type was adenocarcinoma (seven cases, 0.8 %).Among the 724 cases with clear TNM staging, case number of Tis, T1, T2, T3 and T4 stage was eight (1.1%), six (0.8%), 271 (37.4%), 278 (38.4%) and 161 (22.2%), respectively.Among the 122 cases of distal esophageal carcinomas (104 cases with clear TNM staging), most cases were squamous cell carcinoma (112 cases, 91.8 %), the others cases were adenocarcinoma (three cases, 2.5 %), small cell carcinoma (three cases, 2.5 %), basaloid squamous cell, adenosquamous, neuroendocrine carcinomas and carcinosarcoma (one case in each type, 0.8%).Conclusions Esophageal carcinoma was mostly located in the middle segment of in which squamous cell carcinoma was predominant while adenocarcinoma was less common.Esophageal cancer located at lower segment of esophagus is with a wide range of pathological spectrum, squamous cell carcinoma was still dominant, however, esophageal adenocarcinoma is rare.

Objective To explore the effect of long-term chronic mild stress on depression-like behaviors and the expression of heat shock protein 70(HSP70) in rats.Methods The standard SD rats were divided into two groups as following:one group (n =6) was treated with chronic mild stress for 3 weeks,and another group (n =5) was treated with chronic mild stress for 6 weeks.Depression-like behaviors of rats was observed by sucrose consumption test and open field test before and after chronic mild stress.And Western Blot,RT-PCR and immunohistochemistry were utilized to detect the HSP70 expression in the hippocampus and frontal lobes of rats after chronic mild stress.Results The sucrose favoritism in sucrose consumption test,the scores of crossing and the time for rats' retention in the center grid of open field test in long-term group were higher than those in short term group(P< 0.05).HSP70 expression in the hippocampus and frontal lobes of long-term group (0.81 ± 0.08,0.85 ± 0.08)detected by Western Blot and immunohistochemistry was higher that of short-term group (0.60 ± 0.06,0.85 ±0.07).HSP70 expression in the hippocampus of long-term group (0.90 ± 0.05,1.37 ± 0.38)detected by RT-PCR was higher that of short-term group(0.78 ± 0.04,1.08 ± 0.14) (P < 0.05).Conclusion After long-term chronic mild stress,the depression-like behaviors decrease,and at the same time HSP70 mRNA and protein increase.
