Objective To explore propofol dosage difference between in morning and at after-noon undergoing gynecological clinic short operation.Methods One thousands and nine hundred fifty eight female patients,aged 1 6-50 yr,of ASA physical status Ior II,undergoing gynecology clinic short operation,according to the operation time,were divided into two groups,Group morning (8:30-1 1:30,n =1047)and group afternoon (14:00-1 7:00,n =91 1).Each patient was intravenously injected fentanyl 0.01 μg/kg,and then propofol 2.5 mg/kg.When the observer’s assessment of alertness/se-dation (OAA/S)scores reached 0 score,the operation began.If the body moved,the surgery was stopped and 25 mg propofol was intravenously injected quickly.After 10 seconds observation,if the body movement existed,25 mg more propofol was performed,until the movement disappeared.Re-cord patients’year,height,weight,body mass index,and the heart beat,blood pressure of pre-op-eration,the number of times of cervix uteri expansion per vagina,the history of labor per vagina,the total dosage of propofol and the time length of sedation.Results The dosage of group afternoon (1 52.1 6±65.90)mg was higher than group morning’s (135.69±37.67)mg (P <0.05).There was no significant difference of time lengths of sedation between the two groups.Additional use of propofol in the afternoon group 387 (42.5%)was higher than group morning’s 1 99 (23.5%)(P <0.05).Conclusion In gynecological clinic short operation,the propofol dosage in afternoon was higher than that in the morning group.But the sedation time length in afternoon was not longer than that in the morning.

External quality assessment (EQA)as an effective tool for quality control can help clinical laboratories to discover quality problems during testing process and prompt clinical laboratories to improve their testing quality.Samples used for traditional EQA frequently have matrix effects which assign the target value by grouping.Ideal samples for EQA are com-mutable which have the same numeric relationship between different measurement procedures as that expected for patients’ samples.And they can assess accuracy against a reference measurement procedure or a designated comparison method.When analyzing,robust statistical method can be used to reflect the variability of testing results between laboratories more truly. And the evaluation standards should be desirable.If unsatisfactory results appear,we should investigate every aspect of tes-ting process,find the root cause,and take corrective action.On condition that no official EQA scheme is launched for some analytes,it is necessary for us to evaluate the performance of analytes by alternative evaluation procedures.

Objective To study the internal quality control(IQC)designing procedure of the quantitative immunoassay testing i-tem to provide the most suitable IQC rule for the clinical laboratory immunoassay.Methods 3 quantitative detection items of thy-roxine,cortisol and thyroid stimulating hormone were taken for examples.The coefficient of variation(CV)of the method was ob-tained by the repeatability test for evaluating the methodological imprecision.Inaccuracy(bias)was obtained by the methods com-parison.The accuracy of the method was evaluated.Then the most suitable IQC rule for each quantitative detection item was select-ed by plotting the location of the operating point on the normalized operational process specifications(OPSpecs)chart according to CV and bias.Results Two multirule methods of 1 3s/(2of3)2s/R4s/3 1s/6 x and 1 3s/(2of3)2s/R4s/3 1s were identified when the oper-ating point was plotted on the normalized OPSpecs chart for N =6 and 90% analytical quality assurance(AQA)at the thyroxine de-cisive level of 0.064 4 mmol/L.When the cortisol decisive level was 0.735 μmol/L,the normalized OPSpecs chart for N =3 with 90%AQA showed the three solutions of 1 3s/(2of3)2s/R4s/3 1s ,1 2 .5s ,and 1 3s/(2of3)2s/R4s as for thyroid stimulating hormone,3 1s/2 2s/R4s/41s multirole procedure was the best choice for N =4,50%AQA at the upper control level,and the N =2 chart with 50%AQA showed a multirole procedure with 1 3s/2 2s/R4s at the lower control level.Conclusion The suitable internal quality control de-signing procedure of the quantitative immunoassay testing item can be selected by using the OPSpecs chart.

Objective To retrospectively study the value of ultrasonography in diagnosing breast lymphoma and compare with mammography and MRI. Methods Imaging characteristics of 26 patients who were pathologically comfirmed as breast lymphoma were reviewed, including ultrasonography,mammography and MRI, and compare the diagnostic accuracy among the three. Results Twenty-four patients underwent ultrasonography and 32 lesions were found, with longest diameters averaged 30 mm.Tumors were mostly hypoechoic or very hypoechoic (81.3％), some were lobular (25.0％) or oval (21.9 ％ ) in shape, the margins were most frequently circumcribed (62. 5 ％ ), and a few tumors showed an echogenic boundary (18.8 ％ ). Color Doppler imaging showed hypervascularity in most tumors (59.4 ％ ).Ninteen patients undewent mammography, 15 solitary lesions were identified in 12 patients, asymmetric density in five,punctate calcification in one,and no abnormality in one. Eleven lesions were identified in MRI of 10 patients, 10 lesions showed hypointensity on T1-weighted images and hyperintensity on T2-weighted images, and heterogeneous enhancement after contrast. The diagnostic accuracy of ultrasonography,mammography and MRI was 83％, 52％ and 100％, respectively. Conclusions The sonograms of breast lymphoma have some distinct features, the combination of ultrasonography and MRI might benefit the diagnosis of breast lymphoma.

Objective To study ultrasound features of breast cancer before and after neoadjuvant chemotherapy,and its correlation with histopathology. Methods One hundred and nine patients with breast cancer underwent paclitaxel plus carboplatin neoadjuvant chemotherapy, the change of the primary lesions and axillary lymph nodes were studied by ultrasound,and compared with histopathology. Results Seventeen patients achieved complete remission under ultrasound, the rest measurable lesions became significantly shortened in maximum diameter [ ( 22.46 ± 11.50) mm vs (34. 71 ± 13.67) mm, P ＜ 0. 001 ], and showed decrease both in longitudinal-transverse ratio (0. 80 ± 0. 23 vs 0. 86 ± 0. 22, P ＞0. 05) and grades of blood flow (0. 51 ± 0.80 vs 1.23± 1.05, P ＜0. 001 ). 44. 83% (44/92) of metastatic axillary lymph nodes disapeared after treatment. Comparing with histopathology, the sensitivity and specificity of ultrasound assessing complete remission were 57. 89 % ( 11 / 19) and 93.33 % (84/90), respectively. The moderate concord between ultrasound with histopathology might be attributed to the pathologic change of breast tissue and stroma after treatment, nevertheless grades of blood flow might be more meaningful. Conclusions Ultrasound assessment of neoadjuvant chemotherapeutic response might be of reference value,and studying corresponding ultrasonic manifestation of different kinds of pathological changes would help with better evaluation.

Key factors for interpreting proficiency testing (PT)/external quality assessment (EQA) results are knowledge of the commutability of the samples used and the process used for target value assignment.A commutable PT/EQA sample,which would be seen as patients' samples,has the agreement of results among different measurement procedures and demonstrates the same numeric relationship.The value assignment for the sample can be done by using of a reference measurement procedure.Its results can be used to assess the accuracy against a reference measurement procedure or a designated comparison method.Noncommutable PT/EQA samples frequently have a matrix-related bias of unknown magnitude,and can't give meaningful information about the relationship of results for patients' samples among different measurement procedures.Its results must be compared to the peer group mean or the median of results from participants who use measurement procedures that are expected to have the same or very similar matrixrelated bias.

Objective To describe the reference intervals and their sources of tumor markers in clinical laboratories all over China.And make a comparison of difference between different testing systems.Methods The questionnaires about reference intervals of tumor markers testing were distributed to participants.The information was collected by external quality assessment software system based on website, which including upper and lower limits, sources, validation information and testing systems.The analytes were AFP, CEA, total-PSA, CA125, CA153, CA199, ferritin and free-PSA. The participants were classified according to the testing systems they used.The mean, median, maximum and minimum of each group were calculated using Microsoft Excel 2007.The difference of reference intervals between different testing systems were compared by Kruskal-Wallis test.Results The main source of reference intervals was instructions of testing system manufactures ( 83.1% for mean of 8 ratios ) .The next in sequence were instructions of reagent manufactures(8.4% for mean), National Guide to Clinical Laboratory Procedures (4.6%for mean), determined by their own laboratory(2.0% for mean) and the rest (1.9% for mean). There were 48.0% ( 1 906/3 967 ) of analytes whose reference intervals had been validated.Difference of reference intervals which was with P value of Kruskal-Wallis test with <0.05 was found between different testing system groups except the upper limit of free prostate specific antigen ( PSA ) .Conclusions Most clinical laboratories establish the reference intervals of tumor markers on the basis of instructions of testing system manufactures.The reference intervals among different testing systems have statistically significance.
