Objective To investigate the current situation of precision of internal quality control (IQC) in total cholesterol,triglyceride,HDL-cholesterol,and LDL-cholesterol and provide improvement measurements.Methods Web-based External Quality Assessment (EQA) system was used to collect IQCdata of lipid tests from 581 EQA participant laboratories nationwide.The data include the coefficient of variation (CVs) of IQC data under control in April 201 1 and long-term cumulative data.Excel 2007 was applied for data processing after excluding the invalid data.Acceptable rates of CVs of two-lot internal quality controls in 4 lipid testing were calculated according to 6 criteria,that were 1/4TEa,1/3TEa,allowable imprecision of National Cholesterol Education Program (NCEP) and the specifications based on biological variation including the optimal,appropriate and minimal allowable imprecision.Results Four hundred and thirty-five,434,405 and 360 laboratories reported the data of level 1 IQC for total cholesterol (TC),triglyceride (TG),HDL-C,LDL-C respectively,while 214,214,192 and 171 reported the data of level 2 IQC respectively.Acceptable rates of TC,TG,HDL-C,LDL-C based on NECP criteria were 69.2％ (304/435),85.3％ (370/434),61.3％ (48/405) and 69.0％ (248/360) for level 1 respectively while 81.3％(174/214),91.6％ (196/214),75.5％ (145/192) and 81.3％ (139/171) for level 2 respectively.In the group which met the NECP criteria,the proportion of using matching detection system was much higher than the group which did not meet the criteria.Conclusions It is an effective way for clinical laboratories to improve test quality by monitoring the current and cumulative CVs of internal quality control and comparing them against proper evaluation criteria to evaluate if the analysis system can meet quality requirements.

Objective To evaluate the analytical performance of lipid testing with six sigma(a) in order to promote the quality improvement.Methods Sixty-four Laboratories participated in trueness verification program and Internet-Based Interlaboratory Comparison of Internal Quality Control Data program lipid testing in 2012 were included in this study.The CVs and Bias of TC,TG,HDL-C,and LDL-C for each laboratory were evaluated from the reporting data.The sigma metrics based on the Tea from National Cholesterol Education Program according to the formula:σ =(TEa-Bias)/CV for each analyte.Quality goal index (QGI) was also calculated to investigate the reason for dissatisfied performance as follows:QGI =Bias/ (1.5CV).Results The rates for σ≥6 of TC,TG,HDL-C,and LDL-C were 21.9％,34.4％,9.38％,and 18.8％,respectively.The corresponding rates for 3 ≤ σ ＜ 6 were 31.3％,29.7％,29.7％,and 34.4％,while the rates for σ ＜ 3 were 46.9％,35.9％,60.9％,and 46.9％,severally.For analytes which σ were less than 3,91.3％-100％ of the laboratories should improve the trueness first,0.00％-8.75％ of the laboratories should improve the precision,and 0.00％-2.08％ should improve both.Conclusions Six sigma is an effective tool for quality control in clinical laboratory,which can help improve the quality level for laboratory testing.The analysis of performance of the lipid testing shows that further effort is acquired to enhance the supervision of the trueness verification.

Objective:To analyze the clinical effect of different surgical methods on giant-cell tumor of bone (GCTB). Methods:Between January 2007 and June 2012, 37 patients receiving treatment for GCTB were enrolled in this study. These patients included 20 males and 17 females whose ages ranged from 20 to 56 (average=31.6). The prosthesis replacement and nonprosthetic replacement op-eration on the postoperative recurrence, limb function, comprehensive evaluation of the curative effect, as well as morbidity and recur-rence rate among different nations and in the upper and lower limbs of GCTB patients were analyzed. Results:The predilection age of the cases ranged from 20 to 50 years old. The incidence was higher in the Uighur population of Xinjiang, China. However, the recur-rence rate in ethnic difference was not statistically significant (P>0.05). Conclusion:The predilection age of GCTB cases was 20~50 years old, with higher morbidity in Uighur than in Han and other ethnic groups. The morbidity and recurrence rate were higher in the lower limbs than in the upper limbs of patients. The scraping bone graft and bone cement filling, the internal fixation of the scraping bone graft, and the artificial joint replacement of tumor resection were all reliable modes of treatment.

Objective To analyze the pitfalls of 18F fluorodeoxyglucose (FDG) positron emission tomography/computer tomography (PET-CT) scan in the diagnosis of 60 patients of tuberculosis mimicking malignancy.Methods The study included 60 patients with PET-CT diagnosis of probable malignancy.Fifty patients were proved to be tuberculosis by pathological examinations and 10 were diagnosed by clinical followup.The images of whole body were acquired at 60 min after administration of 222-555 MBq 18F-FDG.The PET-CT imaging characteristics and clinical data,including lesion size,distribution,standardized uptake value (SUV) were retrospectively analyzed.After the whole body scan of PET-CT,each patient had a chest spiral CT scan for detailed observation of lung lesions.Contrast enhanced CT (CECT) was performed in 8 patients.Results (1)Thirty patients were misdiagnosed as lung cancer,14 patients as malignant lymphoma,6 patients as malignant mesothelioma,3 as intestine carcinoma,2 as bone malignancy,1 patient as hepatocarcinoma,spleen malignancy,ovarian cancer,laryngocarcinoma and nasopharyngeal carcinoma respectively.(2) 90.9％ (20/22) of patients showed normal level of serum CEA and 100％ (13/13) of patients showed normal level of CA199.Increasing serum CA125 was found in all patients (6/6) with activeTB patients accompanied with ascites,pleural fluid and (or) pericardial effusion.(3) 93.3％ (28/30)active tuberculosis showed accumulated 18F-FDG which was incorrectly interpreted as malignancy.The most common sites of TB lymphadenopathy were bilateral cervical tissues,which was accounted for 85.7％(12/14).CECT revealed characteristics of peripheral enhancement and central necrosis in tubercular lymphadenopathy,which was 87.5％ (7/8).Conclusions The diverse manifestations of TB on imaging and high uptake of 18F-FDG on PET imaging result in misdiagnosis of malignancy.It is important for radiologists and nuclear medicine physicians to identify the common imaging features and patterns of TB to make a correct diagnosis.Integration of reconstruction HR CT,PET-CT and lab examinations may improve the diagnostic accuracy.

BACKGROUND:In mass spectrometry analysis, the same protein in different samples labeled with isobaric tags for relative and absolute quantitation presents the same mass-to-charge ratio, while in the tandem mass spectrometry analysis, the ion signal shows different mass-to-charge ratio (114-121). Thus the quantitative information of the related proteins can be obtained. OBJECTIVE:To establish the protein spectrum of spinal cord tissue differences proteins after acute spinal cord injury, and to explore the spinal differential protein expression on the molecular level using isobaric tags for relative and absolute quantitation combined with LC-MS/MS mass spectrometry technique. METHODS:Eight Sprague Dawley rats were selected to establish the acute spinal cord injury models using Al en’s method. The rats were randomly divided into 0 hour spinal cord injury group and 8 hours spinal cord injury group, four rats in each group. The spinal cord tissues were col ected after injury, and the spinal cord tissue differences proteins were analyzed with isobaric tags for relative and absolute quantitation technique after acute spinal cord injury. RESULTS AND CONCLUSION:Total y 220 differential y expressed proteins were identified in this research, the number of up-regulation proteins was 116 and the number of down-regulation proteins was 104. There were 12 differential proteins related to neural regeneration, and among the 12 proteins, there were seven up-regulation proteins and five down-regulation proteins. The various identified differential proteins and significantly expressed nerve growth factors in this experiment can be used as the biomarkers of acute spinal cord injury or used as the strong evidence for the clinical management and monitoring of the injury process and target therapy of acute spinal cord injury, as wel as the effect evaluation.
