Chinese Journal of Nosocomiology 2006;0(09):-
OBJECTIVE To explore the issues and weakness of hospital infection management at clean operating sector . METHODS Effective preventing and controlling measures of hospital infection, sterilization, isolation , and aseptic technique recommended by WHO were utilized in order to improve investigation and management . RESULTS Quality control was formed in the practice process when sterilization and aseptic technique was performed in routine work at clean operating sector. CONCLUSIONS Hospital infection can be prevented and controlled effectively, patients′ safety coefficient can be improved, and operative infection rate can be lowered when the methods stated in this paper are performed strictly.

Objective To explore the diagnostic value of detecting serum DJ-1 protein combined with CA125 for epi?thelial ovarian tumors. Methods Double antibody sandwich method and electrochemiluminescence immunoassay were used to determine the serum levels of DJ-1 protein and CA125 in 82 cases of epithelial ovarian tumors and 80 non-ovarian tumor cases (control group). The clinical significance of detecting serum DJ-1 protein combined with CA125 was analyzed. Results The expression levels of DJ-1 and CA125 were significantly higher in ovarian tumor group than those in the con?trol group (P<0.05). The critical value of serum DJ-1 was 6.800μg/L and 6.965μg/L in ovarian cancer group compared with the control group and non-ovarian tumor group. The sensitivity of combined detection of DJ-1 and CA125 was higher than that of any marker alone. Conclusion The detecting serum levels of DJ-1 combined with CA125 are helpful to the diagnosis of ovarian cancer, which can be a good marker of ovarian cancer and may improve the early diagnosis rate of ovarian cancer.

OBJECTIVE To study the cause of bacterial infection of ventilator-associated pneumonia(VAP) in intensive care unit(ICU) and summarize effective methods to prevent and control the infection.METHODS Epidemiologic study on 300 patients with VAP in ICU from Dec 1,2003 to Jul 13,2006.Preventing and controlling strategy was as follows.RESULTS Pathogenic bacteria of VAP in ICU mostly were multidrug-resistant ones,of which the G-were 56.3%,G+ were 23% and fungi were 13.7%.CONCLUSIONS To control VAP in ICU proper technique and method are important.Management of hospital infection and related training of staff in ICU are the basic way.

Objective To investigate the immune status characteristics of primary ITP patients with abnor-mal auto-antibodies. Methods A total of 110 patients were enrolled in our study,who were admitted in Fu-Xing Hospital affiliated to Capital Medical University from January 2001 to July 2015.According to whether the patients have autoimmune diseases and the presence of auto-antibodies,we divided the patients into 3 groups,including the primary ITP with abnormal auto-antibodies(PITP-ANA)group,the primary ITP(PITP)group and the second-ary ITP(SITP)group.We compared the T-cell subsets,regulatory T cells,B lymphocytes,changes of immunoglob-ulin and bone marrow biopsy and cytology of patients among the three groups,retrospectively. Results The per-centage of CD3+T cells(61.72 ± 10.60)% in PITP-ANA group was lower than that in PITP group(69.57 ± 11.99)%. The percentage of CD8+T lymphocyte(24.00 ± 7.67)% was significantly lower than that of PITP group (30.59 ± 11.08)%(P<0.05).The proportion of Treg in PITP group,PITP-ANA group and SITP group were(6.12 ± 1.41)%,(7.50 ± 2.76)% and(8.49 ± 2.47)%,respectively,with statistically significant differences.The ra-tio of CD19+T cell in PITP-ANA group(25.75 ± 9.98)%was significantly higher than that in PITP group(16.16 ± 8.19)%(P < 0.01). The concentration of IgG、IgA、κ light chain and λ light chain in PITP group,PITP-ANA group and SITP group showed an upward trend and the highest level was in the SITP group,with statistically signifi-cant differences among the three groups. A variety of abnormal auto-antibodies could be found in both PITP-ANA group and SITP group. Conclusions We consider that the immune function abnormity of patients in PITP-ANA group were worse than that in PITP group,because the concentration of immunoglobulin,the percentage of B lym-phocyte and Treg ratio are higher in than those in PITP group.

Objective To explore the clinical application of ultrasound-guided transabdominal villus and amniocentesis in the prenatal diagnosis of thalassemia,and to find a suitable method for the prenatal diagnosis of thalassemia in Qinzhou.Methods A total of 531 high-risk pregnant women with severe or intermediate thalassemia during single pregnancy who were treated in the Department of Medical Genetics and Prenatal Diagnosis,Qinzhou Maternal and Child Health Hospital from March 2021 to April 2022 were selected for the study.According to different sampling methods,they were divided into control group(amniocentesis,n=415)and study group(transabdominal villus puncture,n=116).The success rate,complication rate of the two groups were compared.Results The success rate of puncture in the control group was 100%,2 cases were aborted within 2 weeks after surgery,17 cases were diagnosed with severe alpha-thalassemia,10 cases with severe β-thalassemia and 64 cases with intermediate thalassemia,48 cases with moderate and severe thalassemia induced labor.The success rate of puncture in the research group was 100%,10 cases were diagnosed with severe alpha-thalassemia,4 cases with severe β-thalassemia and 17 cases with intermediate thalassemia,and 26 cases with moderate severe thalassemia were induced labor.There was no significant difference in puncture success rate and abortion rate between the two methods(P>0.05).Conclusion Both methods are safe and effective.Transabdominal villus sampling can detect fetal thalassemia in early pregnancy,and it is worth promoting and applying in clinical practice.
