ABSTRACT
Objective To investigate the distribution and antimicrobial resistance of Coagulase-negative staphylococci ( CoNS) isolated from cerebrospinal fluids in neurosurgical patients.Methods CoNS strains isolated from cerebrospinal fluids of neurosurgical patients were collected from Beijing Tiantan Hospital of Capital Medical University during January 2013 and December 2015.CoNS infection was diagnosed according to the standards of US Centers for Disease Control and Prevention, and the distribution and antimicrobial resistance of pathogenic CoNS strains were analyzed. Results A total of 19 756 cerebrospinal fluid specimens were collected and 1 386 bacterial strains were isolated, in which 650 (46.9%) were CoNS.Among 650 CoNS strains, 130 were diagnosed as the pathogen, and the top 4 CoNS species were Staphylococcus epidermidis (77/130, 59.2%), Staphylococcus hominis (18/130, 13.8%), Staphylococcus haemolyticus (11/130, 8.5%) and Staphylococcus capitis (9/130, 6.9%).The rest 520 CoNS strains were contaminating strains.According to antimicrobial susceptibility test, there were 103 strains of methicillin-resistant CoNS (MR-CoNS) accounting for 79.1% (103/130).And among 77 Staphylococcus epidermidis isolates, 67 were MR-CoNS strains (87.0%) .More than 90.0%Staphylococcus epidermidis isolates were sensitive to vancomycin and linezolid, and the rest CoNS strains were also highly sensitive to these two antibacterial agents.Conclusions CoNS plays an important role in post-surgery infection in neurosurgical patients, and Staphylococcus epidermidis is the dominant CoNS species.Most CoNS strains are methicillin-resistant, but are highly sensitive to vancomycin and linezolid.
ABSTRACT
Proficiency in pharmaceutical biotechnology requires a solid foundation of theoretical knowledge as well as a capability for research and innovations.A set of practical teaching programs have been developed to train practical talents in pharmaceutical biotechnology.These programs have strengthened the practical teaching system amd trained students to focus on research and innovation. Significant resuits have been found by using internal and external teaching resources and a foeus on key subjects.
ABSTRACT
The construction and management working of clinical practice teaching base is an important component of the western medical colleges and universities.The colleges and universities highlights the status of clinical practice teaching base construction,such as improving construction management system of clinical practice teaching base,strengthening the basic teaching facilities construction,the teachers troop construction and the system construction of clinical practice teaching base,strengthening the organization,teaching and funds management of the clinical practice teaching base and improving the quality and level of graduation practice.
ABSTRACT
Objective To explore the effects of recombinant human hormone(rhGH) on the plasma total protein,plasma albmin,healing of Wound surfaces in patients with the second degree burns wound.Methods 38 pa- tients with the second degree burns wound were divided into treatment group and control group randomly.All the patients were subject general.19 patients in the treatment group were given rhGH in a dose of 0.2U/kg for 14 days beginning from postoperative 5 days.The plasma total protein concentration,plasma albumin concentration,healing rat of wound surface and scar of patients of the two group were compared.Results The plasma total protein concen- tration plasma albumin concentration of the treatment group were significantly in creased,the scar hyperplasia of the treatment group were significantly mitigated and the healing time of wound surfaces of the treatment group were sig- nificantly shortened.Conclusion rhGH is found to promote protein anabotism and shorten the healing time of wound surfaces and mitigate the scar hyperplasia patients with the second degree burns wound.
