Objective To analyze the distribution of pathogens and its characteristics of drug susceptibility originating from nosocomial infections in the intensive care units(ICU) ,and to provide evidence for clinical anti-infection treatments. Methods The data of the pathogens and their chug susceptibility characteristics were retrospectively analyzed. Many kinds of samples were collected in ICU from May 2008 to October 2009. Results There were 605 postive strains and the highest postive rate in sputum. The Gram-postive bacteria strains were 122 ,including 98 strains of staphylococcus where postive β-lactamases were 93. The drug susceptibility rate of linezolid, vancomycin and rifampin was 100% ,98. 2% and 86. 7% ,respectively. However,the drug resistant rate of oxacillin was 98.9%. Totallly 393 strains of the Gram-negative bacteria have been found, where pseudomonas aeruginosa, acinetobactor baumannii,enterobacter cloacae, stenotrophomonas maltophilia and klebsiella spp were 133,106,24,20 and 19 strains, respectively. The drug susceptibility rate of imipenem, aztreonam, levofloxacin and amikacin was 61. 6%, 42.0%, 38.8 % and 36. 1%, respectively. But the drug resistant rate of the third and fourth generation cephalosporin was over 70%. 90 strains of fungi were also found. The most common fungi infection was candida. Conclusion The nosocomial infections in ICU occurs mainly in respiratory tract,most infections are caused by gram negative bacilli. Imipenem and aztreonam have greater susceptibility to treat them. Gram positive coccus still plays an important role in nosocomial infections in the ICU and they high level of resist beta-lactamase-producing drugs. But they are susceptive to linezolid,vancomycin and rifampin.

Objective To explore the nursing intervention of adverse reactions of Iohexol Injection using CT scanning. Methods According to the different nursing intervention mode of patients in our hospital in January January 2015 to January 2017 performed CT scanning using the Iohexol Injection group in 50 cases as control group with routine nursing intervention, the observation group used routine nursing quality nursing intervention;adverse reaction a detailed record of the two groups of patients, and the incidence of adverse reactions compared to investigate the effect of nursing intervention of adverse reactions using the Iohexol Injection CT scan. Results Routine nursing quality nursing intervention (observation group) is better than the clinical effect of CT scanning using Iohexol Injection in patients with routine nursing intervention (control group) clinical the effect and adverse reaction rates in patients with lower than the control group, the difference was statistically significant (P<0.05). Conclusion CT scan. With Iohexol Injection patients regular nursing care, high quality nursing mode intervention effect is remarkable, can effectively reduce the incidence of adverse reactions in patients, it is worthy of clinical widely used.

Background and purpose:Epithelial ovarian cancer has the highest mortality rate of gynecologic cancers and overall survival rates have improved little in the last 20 to 30 years. CXXC ifnger protein 5 (CXXC5) plays an important role in AML (acute myeloid leukemia) and MDS (myelodysplasia). However, little is known about its clinical signiifcance and biological function in epithelial ovarian cancer. This study aimed to investigate the expression of the CXXC5 in ovarian cancer and the effect of the CXXC5 on ES-2 cell proliferation. Methods:①The alteration of CXXC5 in cancer genomics data of TCGA (Cancer Genome Atlas) was analyzed.②The CXXC5 protein in the tissue chips was detected containing 37 benign ovarian cyst and 173 malignant tumor samples. The relationship between the expression of the CXXC5 with the clinicopathological features of patients with ovarian cancer was analyzed by SPSS software;③The cells with the highest CXXC5 expression quantity from 5 ovarian cancer cells were selected by re-al-time quantitative PCR (qRT-PCR) and Western blot.④ES-2 cells with shRNA stable transfection were construted us-ing the strategy of lentivirus infection and analyzed cell proliferation by cell counting kit-8(CCK8). Results:①Through the TCGA database, CXXC5 ampliifcation was found in 7 of 563 cases.②The CXXC5 expression in ovarian malignant carcinoma (39.3%) was higher than that in benign ovarian cyst (13.5%, P=0.003), the histologic type was highly asso-ciated with CXXC5 (43%in serous, 22.9%in mucinous, 23.5%in endometrioid, 67%in clear cell, P=0.014) and there was a signiifcant correlation between CXXC5 and lymph node metastasis (positive vs negative, P=0.022).③The ES-2 cells with shRNA stable transfection had a growth disadvantage (P<0.05). Conclusion:The CXXC5 gene might have an advantage in proliferation of epithelial ovarian carcinoma and be expected to become the biomarker of poor prognosis.

Objective To discuss the application of transanal placement of ileus tube in treatment of colonic obstruction in left colorectal cancer.Methods Thirty-two patients with left malignant colorectal obstruction were divided into ordinary colonoscope group (16 cases) and superslim endoscope group (16 cases) by random digits table.The catheter success rate,catheter operating time and exposure to X-ray time was compared between two groups.Results Fifteen cases were successful and 1 case was failed in ordinary colonoscope group.Thirteen cases were successful and 3 cases were failed in superslim endoscope group.There was no significant difference in the catheter success rate between two groups (x2 =1.143,P =0.285).The catheter operating time was (42 + 15),(20 +6) min in ordinary colonoscope group and superslim endoscope group,and there was significant difference between two groups (t =3.895,P =0.005).The exposure to X-ray time was (20 + 12),(5 + 2) min,and there was significant difference between two groups (t =-3.596,P =0.007).Conclusion Transanal placement of ileus tube is more successful and convenient by superslim endoscope combined with anesthesia than by ordinary colonoscope.
