With the extensive application of informationalized management systems for barcode specimens , the degree of informatization is becoming higher and higher in medical laboratory.Informationalized management combines modern information technology and advanced management concepts , transforms or reengineers the laboratory operation and business process.Test specimen turnaround time ( TAT) is an important factor affecting the quality of the inspection.By analyzing the test process of each time node , establish the suitable specimens monitoring program for clinical requirements and real -time monitor the key nodes in test processes ,which will effectively shorten TAT , improve reporting timeliness rate and avoid clinical complaints.

The Medical Healthcare Service Center,located at the Youxian District,Mianyang City of Sichuan Province,successfully rescued the people affected by the Wenchuan earthquake and the Tangjiashan barrier lake with great help from the senior hospitals.We suggest that the community healthcare service center could play an important role in emergency response system.

Objective To study the alterations in neurobehavior of rats with diffuse axonal injury(DAI) and to evaluate the potential role of basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to build the DAI model.An injection of bFGF subdurally and subcortically was given to the bFGF therapeutic group(n=60).Besides,normal control(n=20) and injured control group(n=60) were established.The elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were adopted to examine the motor and memory abilities.After the implantation of skull electrodes,P3-like potential was explored in rats before and after injury. Results After DAI,the scales of the elevated walkway test,prehensile traction test,sensorimotor integration test and the Morris' water maze test were decreased,and the rats in the bFGF therapeutic group presented a better behaviour in the early stage.The latency of P3-like potential prolonged significantly in rats with DAI,with the P3-like potential in the injured control group longer than that in the bFGF therapeutic group(P

Objective To study the alterations in pathology and immunohistochemistry in rats with diffuse axonal injury(DAI) and the effects from basic fibroblast growth factor(bFGF). Methods A weight-drop device was employed to produce DAI in rats.In the treatment group(n=60),bFGF was injected subdurally and subcortically.Besides,normal control group(n=20) and injury-control group(n=60) were also established.The pathological changes were observed by light microscopy and electromicroscopy,and the expression of brain-derived neurotrophic factor(BDNF),growth associated protein-43(GAP-43) and glial fibrillary acidic protein(GFAP) were also examined by immunohistochemistry. Results Typical pathological changes were observed in the basal portion of pons,corpus callosum and white matter of cerebral hemisphere in the rats with DAI.And an upregulation of GFAP,GAP-43 and BDNF was also found.In the treatment group,better outcomes of pathological changes were observed.bFGF increased the expression of BDNF and GAP-43,while inhibited the immunoreactivity of GFAP. Conclusion Topical application of bFGF can improve brain tissue regeneration and speed function recovery in rats with DAI,though its long-term effect warrants further study.

Objective To evaluate the assistant diagnostic value of low dose CT in patients with pulmonary embolism (PE) based on ventilation/perfusion (V/Q) SPECT imaging.Methods One hundred and two patients with clinical suspected PE had been enrolled for this retrospective study.The final diagnosis of PE was made according to the 2008 guidelines of European Society of Cardiology (ESC).All patients underwent V/Q SPECT/CT (Hawkeye 4,GE).The imaging findings from low dose CT lung window were used for differential diagnoses of abnormal regions in SPECT imaging.The diagnostic efficiency of V/Q SPECT alone was compared with that of V/Q SPECT combined with low dose CT scan.Crosstabsx2 test was performed using SPSS 13.0 software.Results Twenty-nine patients (28.43％,29/102) were finally diagnosed as PE.V/Q SPECT alone had a sensitivity of 93.10％ (27/29),a specificity of 90.41％ (66/73),and an accuracy of 91.18％ (93/102).With additional diagnostic information from low dose CT,the diagnostic specificity increased to 95.89％ (70/73,X2 =1.72,P ＞ 0.05 ),and the accuracy increased to 95.10％ (97/102,x2 =1.23,P ＞ 0.05) though the sensitivity remained the same.Conclusion Imaginginformation from low dose CT in hybrid SPECT/CT may enhance V/Q diagnostic accuracy for PE.
