Objective: To investigate the peri-operative incidence of depression and anxiety symptoms of coronary artery bypass grafting (CABG). Methods: 73 patients,who underwent scheduled consecutive CABG between July 2005 and May 2006,were assessed with self-rating depression scale( SDS) and self-rating anxiety scale(SAS)before operation and before leaving hospital.Results: 21 patients (28.8%) had depression and/or anxiety symptoms before CABG, including 11 patients with depression, 7 patients with both depression and anxiety and the other 3 patients had anxiety symptoms. 34 patients (46.6%) had depression and/or anxiety symptoms after CABG, including 18 patients who had depression, 13 patients had both depression and anxiety symptoms and the other 3 patients had anxiety symptoms. The SDS score(47.9?10.0)after surgery was significantly higher than that before surgery(43.7?10) ,t=3.55, P=0.001. The SAS score after surgery (41.6?8.5) was significantly higher than that before surgery (39.3?7.4),t=2.20, P=0.031. Patients with bad mood before operation had lower educational levels (8?3/10?3,t=2.18,P=0.032). Four patients had multiple myocardial infarctions, all of them were in the anxiety-depression group postoperatively (4/34 vs 0/39,P=0.043). There was no difference in post-operative length of hospital stay between the two groups.Conclusions: The peri-operative incidence of depression and anxiety of CABG patients was very high and even higher after surgery. Less education is a risk factor for preoperative depression and anxiety states, multiple infarctions is a risk factor of post operative anxiety and depression.

Objective To explore the value of water -based material decomposition images for detection of bone marrow edema (BME)in sacroiliitis with energy spectral CT.Methods The sacroiliac (SI)joints of nine spondyloarthropathy patients with sacroiliitis (the research group)and eight healthy volunteers (the control group) were underwent MRI and energy spectral CT.The mixed energy image of energy spectral CT was reconstructed to be mono energy image.Then,the mono image was divided into water -based image and calcium image by material divid-ed and analyzed software.The SI para -articular marrow region water -calcium relative concentration of research group was compared with that of control group.The BME diagnosis efficiency and optimal water -based concentration of energy spectral CT was analyzed by receiver operating characteristic (ROC)curve.Then,the sensitivity,specificity, positive likelihood ratio and negative likelihood ration were calculated.Results The water -based concentration of BME in research group (1 067.43 ±10.84)g/L was higher than that of control group (1 039.43 ±8.01)g/L(t =-3.14,P =0.003).Meanwhile,the calcium -based concentration of research group (68.98 ±20.53)g/L was not different from control group (78.03 ±26.39)g/L(t =1.88,P =0.066).ROC curve showed that the diagnosis efficiency was medium as the area of under curve was 0.75.When the optimal concentration of water -based was 1 052.00g/L,the diagnosis efficiency was the best.The sensitivity and specificity was 84.00%,62.50% respectively. Conclusion There are reference value and potential clinical value with energy spectral CT water -based concentra-tion detection for diagnosis BME in patients with sacroiliitis.

Objective To explore pathogen spectrum constitution of acute diarrhea in outpatient and emergency of Zhejiang Province, and provide basis for treatment, prevention and control of the disease. Methods During January 2009 to December 2014, we selected seven sentinel hospitals in different regions of Zhejiang, monitored and researched on pathogen spectrum in patients with acute diarrhea from outpatient and emergency. We recorded patients' personal basic information, the main symptoms and signs, and collected stool samples (5 g). Eight kinds of bacteria (Vibrio cholerae, Shigella spp., Salmonella spp., Diarrheagenic E. coli, Vibrio parahaemolyticus, Aeromonas hydrophila, Yersinia enterocolitica and Plesiomonas shigelloides) and five kinds of viruses (Rotavirus, Norovirus, Sappovirus, Astrovirus and Adenovirus) were detected. Chi-square test and Fisher's exact probability method were used to compare different characteristics of patients with single bacterial infection, single virus infection and multiple infection (bacteria-bacteria, bacteria-viruses, virus-virus). Results During 2009 to 2014, 9 364 fecal
samples from acute diarrhea patients were collected and tested, among which 3 500 cases were tested positive, with total positive rate of 37.38%. Positive rates of bacteria and viruses were 13.14%(1 230 cases) and 20.75%(1 943 cases), respectively. Mixed infection positive rate of multiple pathogens was 3.49%(327 cases). Positive rate of Vibrio parahaemolyticus (5.96%, 558 cases) was the highest among bacterial pathogens, followed by pathogenic Escherichia coli (3.86%, 361 cases). Viruses were mainly Norovirus (10.73%, 1 005 cases) and rotavirus (8.35%, 782 cases). A big difference existed in diarrheogenic pathogen spectrum between patients less than 15 years old and patients equal or older than 15 years old. Pathogens for patients less than 15 years old were mainly virus, with the positive rate of 32.69%(1 014 cases). However, the positive rate of bacteria was 16.86% (1 056 cases) in patients equal or older than 15 years old. Single bacterial infection was highest in age group of 25-34 years old (18.62%, 302 cases) , single virus infection was highest in age group of 1-4 years old (41.12%, 435 cases) , and mixed infections of multiple pathogens were mainly existed in age group of 1-4 years old (7.37%, 78 cases) . Pathogen positive rate were increasing year by year. Pathogen positive rate of patients with acute diarrhea has obvious seasonality, with single bacterial infection being highest during July to September and single virus infection being highest during December to March. Pathogen spectrum of outpatient and emergency patients with acute diarrhea in Zhejiang Province changed a little from 2009 to 2014, mainly rotavirus (22.34% (782/3 500)), norovirus (28.71%(1 005/3 500)), vibrio parahaemolyticus (15.92%(558/3 500)) and Escherichia coli (10.31%(361/3 500)). However, pathogen spectrums in different years owned different features. Conclusion Common pathogens in outpatient and emergency patients with acute diarrhea in Zhejiang Province were tested with significant seasonal epidemic law. The composition of pathogenic spectrum was variant in different age group. Constitutes of major pathogen spectrum in different years differed a little.
