This article introduced the practice of tertiary hospitals′ clinical laboratories in making full use of its advantageous medical resources ,and using community centralized detection service. The authors hold that public hospitals have more advantage and needs to use this service ,and such a centralized model requires further innovation and improvement. Participation in centralized service by these clinical laboratories enjoys a good development prospect .

Objective To establish the central tube preparation system for the blood samples from hospitalized patients in clinical laboratories and explore its application value.Methods A central tube preparation system for clinical specimen was researched and developed.The system was directly connected with the laboratory information management system (LIMS) and hospital information management system (HIMS) for monitoring and tracking management on-line with standardization,intellectualization and informatization during the whole process of collection,detection and report of clinical specimens.Results The central tube preparation system for blood samples from hospitalized patients in clinical laboratories was successfully established.The development and application of this system optimized the blood collection process,avoided incidental human mistakes in traditional blood collection process,realized the real-time monitoring of the clinical samples during the whole process and reduced the labor intensity of nurses.Therefore,the working efficiency and degree of clinical satisfaction were increased greatly.Conclusion The developed system could process the specimens intelligently,improve the management level of hospital and department and provide guarantee for standardized management of clinical laboratories.

Objective To establish a networked information management system for clinical laboratories in community of Suzhou and evaluate its clinical application.Methods Based on dedicated network of public health information in Suzhou City,laboratory information management system (LIS) and hospital information management system (HIS),the management for centralized detections of clinical samples from the health institutions of intra-regional community were performed as the key mission,and a regional,networked and informationized management system was designed for the clinical laboratories of community.Results The informationized management of whole process including test application,specimen collection,delivery and receiving,report releasing and payment,etc.was achieved on line.The information of clinical laboratories among the communities was transferred and shared in whole Suzhou City.Conclusion The established system should be safe,convenient and efficient online network-based information management system between the Suzhou clinical laboratory center and the laboratories in each local community,by which the centralized detections in the clinical laboratories of community could be performed readily.

Objective To explore the relationship between the type of TORCH infection and pregnancy outcome through the de-tection of TORCH infection in pregnant women with IgG avidity index (AI) .Methods Collected each type of TORCH pathogens IgM positive maternal serum ,and detect the IgG avidity index and track the outcome of pregnancy .Results The rate of TORCH pathogens recent infection (AI<30% )in pregnant women ,HSV ,RUB ,CMV ,TOXO respectively were 0 ,3 .8% ,9 .3% ,7 .9% ;In the group of pregnant women with TORCH-IgG AI<30% ,there were 2 cases of pregnancy outcome of abnormal (missed abortion) and one case of fetal malformations (hydrocephalus) .Conclusion In the recent infection of TORCH pathogens in pregnant women , mainly are non-primary infection ;The damage of cytomegalovirus and Toxoplasma gondii primary infection to the fetus is much larger than the non-primary infection .

BACKGROUND: The dramatic increase in use of the IgG test for toxoplasma, rubella, cytomegalovirus (CMV), and herpes simplex virus (HSV) [TORCH] has led to the requirement for a high-efficiency method that can be used in the clinical laboratory. This study aimed to compare the results of BGI-Array ELISA TORCH IgG (BGI-GBI, China) screening method to those of Virion/Serion TORCH IgG ELISA (Virion/Serion, Germany). METHODS: Serum specimens (n=400) submitted for routine IgG testing by Virion/Serion ELISA were also tested using the BGI-Array ELISA method. The agreements of these two kinds of method were analyzed by kappa-coefficients calculation. RESULTS: Following repeat testing, the BGI-Array ELISA TORCH IgG assays demonstrated agreements of 99.5% (398/400 specimens), 98% (392/400 specimens), 99% (396/400 specimens), and 99.5% (398/400 specimens), respectively. The BGI-Array ELISA IgG assays provided results comparable to Virion/Serion ELISA results, with kappa-coefficients showing near-perfect agreement for the HSV (kappa=0.87), rubella (kappa=0.92) and CMV (kappa=0.93) and substantial agreement for the toxoplasma (kappa=0.80) IgG assays. The use of the BGI-Array ELISA TORCH IgG assays could reduce the turnaround time (1.5 hr vs. 5 hr by Virion/Serion ELISA for 100 specimens) and were easy to use. CONCLUSIONS: BGI-Array ELISA TORCH IgG shows a good agreement with Virion/Serion ELISA methods and is suitable for clinical application.

BACKGROUND: This study was aimed to investigate the genetic diversity and antibiotic resistance profile of the nosocomial infection agent Acinetobacter baumannii from a medical intensive care unit (ICU) in a teaching hospital in Suzhou, China. METHODS: The genetic relationship among A. baumannii isolates in an ICU was investigated using multilocus sequence typing (MLST). The antibiotic resistance pattern was determined by performing an antibiotic susceptible test, which included an agar dilution method and an E-test method. Resistant determinants, e.g., carbapenemase genes, metallo-beta-lactamases, and class 1 integron, were analyzed by specific PCR and DNA sequencing. RESULTS: In the present study, 33 non-duplicate isolates were identified as 5 existing sequence types (STs) (ST92, ST75, ST112, ST145, and ST345) and 1 new sequence type STn, which has a G-A mutation at nt268 on ropD40 of ST251. These results reveal limited diversity in carbapenem non-susceptible A. baumannii (CNSAb) isolates in our ICU, which are comprised of only 2 distinct STs, with ST92 and ST75 clustering into a clonal complex (CC) 92. Most CNSAb isolates (94.4%, 17/18) harbored the OXA-23 gene, while no carbapenem-susceptible A. baumannii (CSAb) isolates harbored it. In addition, 66.7% (22/33) isolates were positive for class 1 integrase, and gene cassette analysis showed there are 3 gene arrays among them, i.e., aacA4-catB8-aadA1 (77.3%, 17/22), aacA4 (22.7%, 5/22), and aacC1-orfX-orfX'-aadA1 (4.5%, 1/22). CONCLUSIONS: When all these data are combined, the antibiotic resistance and wide distribution of CNSAb isolates in our ICU are probably caused by expansion of the CC92 clone.
