OBJECTIVE: To investigate the compatible stability of cefotiam hydroloride for injection with fructose injection.METHODS: The content changes of the mixture within 8h at 25℃ were determined by UV spectrophotometry,and its external appearance was observed,and the pH value as well as particle size of the mixture were measured.RESULTS: The mixture was clear within 6h,showing no visible changes in appearance,pH value and contents of cefotiam,with particles in line with the standard stated in China Pharmacopeia(2005 edition).CONCLUSION: The mixture of ceforiam hydrochloride for injection and fructose injection is stable within 6h.

Objective:To investigate the antimicrobial resistance spectrum of Escherichia coli isolated from different clinical sam-ples to guide the nosocomial infection control and rational use of antibiotics. Methods:Escherichia coli from clinical samples were isola-ted and tested by microbiological assay system of BD Phoenix 100 and susceptibility test card in 2013. The drug resistance was analyzed and compared retrospectively. Results: There were 936 strains of Escherichia coli isolated from our hospital in 2013. Escherichia coli was resistant to common antibiotics at high level. Escherichia coli strains isolated from different samples varied in the drug susceptibili-ty. The resistance rate of the strains from sputum samples was higher than that from the other samples. Conclusion:The status of drug resistance of clinical isolated Escherichia coli to antibiotics is very serious. Escherichia coli isolated from different samples show different drug resistant features, and the antimicrobial therapy should be considered according to the antimicrobial susceptibility tests.

Objective To investigate the clinical and pathological characteristics, diagnosis and differential diagnosis of uterine intravenous leiomyoma (IVL) , so as to improve the detection of the disease.Methods Five cases of IVL were retrospected, who were treated and diagnosed by clinical gross examination,morphologic features and immunohistochemical staining in Tumor Hospital of Anyang from 2011 to 2015.Results Symptoms of IVL were usually nonspecific, most patients experienced hypermenorrhea, abdominal pain or distension, and pelvic mass.Typical pathological changes were intravenous visible grey weblike or worm-formed nodules, which could be pulled out.Microscopically, the tumors were composed of mild spindle-shaped cells with rare mitotic figure and closely related to blood vessels.The tumors were positive for smooth muscle derived marker, progesterone receptor, estrogen receptor, and negative for S-100, HMB45 and CD34.However CD34 can displayed vascular endothelial cells around the tumor.Conclusion Uterine IVL is a benign tumor with malignant biological behavior, which has different clinical pathological features of leiomyoma ordinary.Surgery is the main treatment method.A satisfactory therapeutic effect can be achieved by selecting the appropriate extent of surgery.Long term follow up of iVL patients after operation is important.
