Future competition in the medical market will in essence be the contest of the core competitiveness of hospitals.It is therefore imperative for hospitals to do a good job in the following aspects in light of trends in medical development,the state of its resources and the needs of the market: enhancing their awareness of the importance of scientific and technological work,setting up a rationally distributed scientific research system,strengthening personnel and disciplinary development,improving the quality of scientific and technological management personnel,and establishing standardized systems for scientific and technological management.The goal is to enhance core competitiveness so as to gain competitive edges for sustainable development.

Objective:To analyze the drug resistance of Pseudomonas aeruginosa( PA) isolated from clinical specimen to provide the guidance for the clinical treatment. Methods:The infection status of PA from January 2012 to December 2012 was reviewed retro-spectively, and the results of susceptibility test for 448 PA strains were analyzed. Results:The antibiotic susceptibility of the PA strains to cefoperazone sodium and sulbac, ampicillin aodium and aulbacta,aiprofloxacin,cefepime,piperacillin/ sulbactam,amikacin, ceftazi-dime,meropenem, imipenem, minocycline, selectrin and aefuroxime was 100%, 76%, 72. 8%, 69. 4%, 66. 3%, 65. 6%, 64. 8%, 59. 9%,28. 9%,2. 4% and 0%,respectively. Conclusion:PA is one of the main pathogenic bacteria for nosocomial infection. It is necessary to strengthen the drug resistance test and standardize the application of antibiotics in order to provide the reference for clinical rational use of antibacterial drugs.

Objective To investigate the effect of personality characteristics on near-term postoperative mental health of patients with laryngeal squamous cell carcinoma (LSCC). Methods We included 119 patients with LSCC who underwent surgical treatment. The recent psychological state was assessed by SCL-90, SAS and SDS 5 to 7 days after surgery. The EPQ was used to evaluate the personality characteristics of patients after operation. Multiple linear stepwise regression method was used to analyze the influencing factors of SAS and SDS scores of LSCC patients. Results The postoperative scores of SCL-90, SAS and SDS of LSCC patients were significantly higher than the Chinese norm (P≤0.05). The scores of P scale and N scale in EPQ were higher than the domestic norm (P < 0.01). The scores of somatization, obsessiveness, anxiety, depression, hostility, phobia, paranoia and psychosis were significantly higher than the Chinese norm (P < 0.05). Family income, surgical method, postoperative radiochemotherapy, psychoticism and neuroticism personalities were the influencing factors of postoperative SAS score (P < 0.01). Family income, surgical method, postoperative radiochemotherapy, neurotic personality were the influencing factors of postoperative SDS score (P < 0.01). Conclusion LSCC patients have near-term depression, anxiety and other psychological disorders after operation. In terms of personality, they have psychoticism and neuroticism. Family income, surgical methods, postoperative radiochemotherapy, psychoticism and neuroticism are independent risk factors affecting postoperative SAS and SDS scores.

BACKGROUNDTo detect quantitatively HCMV DNA in peripheral blood leukocytes to monitor the status of HCMV infection, evaluate the effectiveness of antiviral treatment with ganciclovir (GCV) combined with intravenous immunoglobulin (IVIG) and find out the relationship among the HCMV DNA levels, the state of infection and the clinical outcome.The long-term goal of the study was to establish a molecular diagnostic standard for HCMV infection in children.

METHODS45 cases of suspected HCMV-infected children were examined by PCR, ELISA and fluorescent quantitative (FQ)-PCR, respectively. Twenty five HCMV hepatitis cases of the 45 were randomly assigned to a treated group or a control group. Both groups were treated with prednisone, glucurone, Luminal and Xiaoyanlidanpian. But the treated group was given with GCV+IVIG in addition. Each infant of the two groups was checked with FQ-PCR at the five time points.

RESULTSThe positive rates of PCR, ELISA and FQ-PCR were 60.00%, 33.33% and 66.67%,their sensitivities were 84.38%, 46.88% and 93.75%, respectively. There was no significant difference in viral DNA copy numbers between the two groups before being treated (P>0.05), but there was significant difference between HCMV hepatitis and normal infants (P<0.001). Although viral load of both groups decreased in both groups, the viral load of the treated group decreased more significantly. The level of HCMV DNA fell to 103 copies/ml at second time point while that of the control group fell to the same level after third time point. The differences between the two groups at each time point were statistically significant (P<0.001). The results of 135 person times testing indicated that 103 copies/ml of FQ-PCR can be taken as a critical value for prediction of active HCMV infection.

CONCLUSIONSFQ-PCR may be one of the effective methods for diagnosis of HCMV disease; it can offer a key index in the diagnosis of HCMV active infection; dynamic detection of HCMV viral load can play a role not only in monitoring antiviral therapy, but also in evaluating the development and prognosis of HCMV disease.
