ObjectiveTo investigate the clinical features,early diagnosis and therapeutic methods of primary tumor of the duodenum.MethodsThe clinical data of 130 patients of primary tumor of the duodenum who were hospitalized in Peaking University Third Hospital from 1974 to 2010 were summarized.There were 30 cases of benign tumors and 100 cases of malignancy. ResultsMore than 90％ of primary tumors of the duodenum were located at the duodenal bulb and descendent part.59％ of malignant tumors were located in the area of duodenal papilla. The mean diameter of benign tumors was less than 2 cm compared with more than 3 cm in malignancies. Upper abdominal pain,jaundice,black stool,intestinal obstruction and abdominal mass were among the most common clinical manifestations. Jaudice was most common in papilla tumors,and intestinal obstruction and palpable abdominal mass often indicate advanced stage.Duodenofiberscopy combined with air barium double contrast radiography increase the diagnosis rate.Among the 30 benign cases,11 cases underwent simple tumor resection,14 cases received endoscopic tumor resection and 3 cases underwent pancreaticoduodenectomy.Resection rate and the 5-year survival rate was 100％. Of the 100 malignant cases,56 cases underwent standard pancreaticoduodenectomy,3 cases received pylorus preserving pancreaticoduodenectomy,9 cases underwent simple tumor resection and 12 cases received segmental duodenectomy.Resection rate was 84％.The 5-year survival rate was 46％ in 59 cases receiving Whipple's procedure.ConclusionsPrimary tumor of the duodenum lacks specific clinical features. Simple tumor resection and segmental duodenectomy can be done for benign cases, while pancreaticoduodenectomy is the therapy of choice for malignant cases.

OBJECTIVE:To provide experience and reference for the reform ofintegration of medicine and nursingunder the strategy ofHealth China 2030. METHODS:By literature analysis,the demand characteristics and supply situation ofinte-gration of medicine and nursingservice model in China were analyzed. The development bottleneck ofintegration of medicine and nursingservice model in China was discussed to put forward countermeasures and suggestions. RESULTS&CONCLUSIONS:Integration of medicine and nursingis a new model of the development of pension services in China. Throughout whole country, it is still in the stage of exploration and practice. There are some problems,such as serious inadequate beds,low participation of private pension institutions,pension service quality ofintegration of medicine and nursinghaving to be improved,weak market competition of pension institutions,social forces participation having to be improved,big demand gap of medical and nursing staff,inadequate high-quality medical and nursing talent.

Depression is one of the diseases with the highest disability rate in the world. A large number of studies have shown that the intake of unsaturated fatty acids can deal with depression while chronic overconsumption of saturated fatty acids is a risk factor for depression. It was suggested that the mechanism of saturated fatty acids inducing depression is related to the following four aspects: regulating the function which links to depression in whole brain and specific brain regions, including the hippocampus, the hypothalamic-pituitary-adrenal axis, the striatum, and the prefrontal cortex; stimulating the secretion of inflammatory factors; affecting the balance and function of metabolic regulatory hormones, including leptin, adiponectin, glucocorticoid, and insulin; inducing the disturbance of intestinal flora. This article reviews the relationship between dietary fatty acids and depression, and the possible mechanisms by which saturated fatty acids induce depression from the four aspects mentioned above.

Objective To characterize composition and antibiotic resistance of the pathogens isolated from patients' deep sputum with ventilator-associated pneumonia(VAP) in PICU of our hospital,and give support to the administration of antibiotics early and reasonably in clinic.Methods The study was conducted during the period of January 2009 to December 2013 at PICU of the Children's Hospital of Zhejiang University School of Medicine.One hundred and twenty-one cases of children who conformed to the diagnostic criteria of VAP after treated with ventilator were the object,the endotracheal aspirates were collected and transported to microbiology laboratory within 15 minutes.The pathogens were routinely analyzed and identified with WITEK60 and used Kirby-Bauer method for drug sensitive test,and identified with the special drug-resistant bacteria.Results Among 121 VAP diagnosed patients,127 pathogenic strains isolated from sputum specimen.Gram negative,Gram positive bacteria and fungi accounted for 64.57％ (82/127),29.92％ (38/127)and 5.51％ (7/127) respectively.Acinetobacter baumannii (25.61％,21/127),Escherichia coli (20.27％,17/127),Stenotrophomonas maltophilia (20.27 ％,17/127),Klebsiella pneumoniae (16.22％,12/127) and Pseudomonas aeruginosa (9.46％,11/127) were frequently identified isolates among Gram negative bacteria.The resistant rate of Gram negative bacteria in β lactam antibiotics was 77.62％.Ten strains of Staphylococcus epidermis and 6 strains of Staphylococcus aureus were identified isolates among Gram positive bacteria.Except the sensitive to vancomycin and linezolid,Gram positive bacteria were resistance to cephalosporin and aminoglycosides.All fungi were sensitive to the anti-microbial agents.Conclusion The Gram negative bacteria were more prevalent than Gram positive bacteria and fungi in VAP and show high drug resistance.It is pivotal to administer anti-microbial agents early and reasonably for VAP children.To emphasize surveillance to the antibiotic resistance and grasp the characteristics of the drug resistance are much important to VAP therapy.

Objective:To analyze and evaluate the degassing effect of vacuum degassing apparatus through the determination of ox-ygen content in pure water, gas pressure and air volume, and compare with suction filtration, boiling and ultrasonic methods to choose the appropriate degassing method for dissolution medium and guide the daily inspection work. Methods: The water residual oxygen, gas pressure and air volume were determined using a single water quality on-line monitoring instrument and a Carbo QC Anton Pear in-strument. The degassing effect of the vacuum degassing apparatus was detected under the conditions of negative pressure and certain de-gassing time. The degassing effect was also compared with that of suction filter, boiling and ultrasonic methods. Results: Under the conditions of 0. 06 MPa negative pressure, 41℃ medium temperature and 30 min degassing time, the degassing effect of the vacuum degassing apparatus was obvious. The degassing effect of suction filter and boiling methods was similar to that of the vacuum degassing apparatus, while that of ultrasonic method wasn't obvious. Conclusion:The use of vacuum degassing apparatus is simple and efficient with obvious degassing effect, which is suitable for the degassing process of dissolution medium.

BACKGROUND:Platelet-rich plasma has benefit in diabetic wound healing;however, the effect of al ogeneic platelet-rich plasma is stil unclear. OBJECTIVE:To observe the effect of al ogeneic platelet-rich plasma on col agen synthesis during diabetic wound healing. METHODS:Streptozocin-induced diabetic rats were randomly divided into al ogeneic platelet-rich plasma group and saline control group. Each group had 15 rats. A 1 cm2 ful-thickness skin defect on the rat dorsum was excised. Platelet-rich plasma or saline was applied. Platelet-rich plasma was prepared from the whole blood of al ogeneic healthy rats. Animals of each group were sacrificed on 3, 7, 14 days post operation. The differences of the wound closure rate, morphological character, hydroxyproline content and the relative mRNA expression of the col agen were observed. RESULTS AND CONCLUSION:The wound closure rates were lower in control group on day 3, 7, 14 post operation (P<0.05). Masson staining showed a decreased, disorder, loose col agen fibers distribution in diabetic control wound tissue. The results of the hydroxyproline test showed hydroxyproline content was significantly higher in platelet-rich plasma group at each time point (P<0.01). The relative mRNA expression of type I and III col agen presented a higher expression in platelet-rich plasma treated wound tissue at each time point (P<0.05). And the ratio between type I and III col agen was higher in platelet-rich plasma group at each time point (P<0.05). In summary, al ogeneic platelet-rich plasma can promote diabetic wounds healing, which may attribute to an enhanced col agen synthesis.
