Objective To determine the biological reference interval of urinary conductivity in healthy people and to study the relationship between urine conductivity and other parameters as well as its clinical feasibility.Methods Conductivities of midstream urine specimen from healthy people (n=10119,5074 males and 5045 females,aged under 96 years) or patients with different diseases (n=3449) were determined.Among them the following parameters:conductivity,osmolality,specific gravity,creatinine,urea,uric acid,sodium,potassium and chloride of 250 random urine specimens were simultaneously determined.Results The urinary conductivities in healthy people exhibited normal distribution and significant differences were found in the subjects with different age and sex.The reference range of urinary conductivity was between 10.42?4.61 mS/ch and 24.10?6.81 mS/ch in healthy people and between 7.95 mS/ch?2.40 and 18.01?5.90 mS/ch in the patients with different diseases.Conductivity determined was positively correlated with osmolality (r:0.894),specific gravity (r:0.727),sodium (r:0.698),potassium (r:0.563),chloride (r:758),uric acid (r:0.521),urea (r:0.556) and creatinine (r:0.495).Conclusions Urine conductivity,which determination is simple and rapid,may reflect the conductive capacity of electrolytes in urine and positively correlated with osmolality,so it can be used as a new parameter for urinalysis to diagnose renal concentrative function in routine laboratory.

ObjectiveTo investigate the association of phosphorylation of mammalian target protein of rapamycin (pmTOR) expression with glioma malignancy grades,and the correlation of pmTOR expression with Survivin and Ki-67,which represent tumor cell anti-apoptosis ability and reproductive activity.MethodsImmunohistochemistry EliVision method was employed to detect the expression of pmTOR,Survivin and Ki-67 in paraffin tissues from 87 patients with glioma (grade Ⅰ - Ⅱ 27 cases,grade Ⅲ24 cases and grade Ⅳ 36 cases).The association between positive expression rate,level of pmTOR and malignancy grades,and the correlation of its expression level with Survivin and Ki-67 were further evaluated.Results There was no significant difference in the positive expression rate of pmTOR among grade Ⅰ - Ⅱ(77.8％,21/27),grade Ⅲ(75.0％,18/24) and grade Ⅳ (72.2％,23/36) (P ＞ 0.05).However,the significant association between pmTOR expression level and malignancy grades was observed.The expression from 87 patients with glioma was significantly positively correlated with Survivin and Ki-67 expression level (r =0.858,P ＜ 0.01 ;r =0.708,P ＜ 0.01 ).ConclusionsThe expression level of pmTOR is associated with malignancy grades,tumor cell anti-apoptosis ability and reproductive activity.pmTOR may be served as a useful marker for predicting the biological behavior of glioma and a useful target for gene therapy.

ObjectiveTo establish the proper review rules for the microscopic screening of urine samples tested by automatic urinalysis work station which is composed of LabUMat urine dry chemical analyzer and Urised urine sedimental analyzer.Methods The paired comparison was used to analyze the results tested by microscopy and Urised.A total of 2015 random urine samples were enrolled to establish and validate review rules.All the samples were collected from the inpatients and ontpatients of General Hospital of the People's Liberation Army from May to November 2011 and tested by urinalysis work station.2015 urine samples were firstly tested by urinalysis work station,including both urine dry chemical analyzer and urine sediments analyzer.Then each urine sample was examined microscopically by two technicians-in-charge using double-blind method.The average results from the two technicians were used as review results.Compared with review results,we set up the review rules and evaluated the Irue positive rate,false positive rate,true negative rate,false negative rate (omission diagnostic rate) and review rate.According to different test methods by automatic urinalysis work station,four microscopic review protocols were defined:( 1 ) Protocol 1:based on chemistry results only,microscopy review was performed when any of WBC,RBC,PRO and NIT was positive; (2) Protocol 2:based on urine sedimental analysis only,microscopy review was performed when any of WBC,RBC and CAST count was over upper limit of the reference range ; (3) Protocol 3:if any of BLD vs.RBC,LEU vs.WBC was different between two systems,or quantitative results had two or more than two gradient differences,microscopy review was performed; (4) Protocol 4:if any of BLD vs.RBC,LEU vs.WBC was different between two systems,or CAST was over upper limit of the reference range,or alam appeared,microscopic review was performed.300 randomly selected urine samples were tested to validate the review rules.Omission diagnostic rate and review rate were used to evaluate the rules.Results According to our review rules,the positive samples rate was 41.14％ (829/2015) and the negative rate was 58.86％ ( 1186/2015 ) ; Positive samples were composed of RBC (50.30％),WBC (53.32％) and CAST (3.74％).The review rates of four protocols were 42.93％ (865/2015),39.70％ (810/2015),29.58％(596/2015),18.91％ (381/2015 ),respectively.The false negative rates (omission diagnostic rates) were 6.36％ (128/2015),4.42％ (89/2015),1.34％ (27/2015)and 1.04％ (21/2015)respectively.Protocol 4 was selected as an ideal plan.Additional 300 urine samples were tested using protocol 4 in order to confirm the review rule.The review rate,consistency rate,true positive rate,false positive rate,true negative rate,omission diagnostic rate were 19.67％ (59/300),91.67％ (275/300),35.67％ (107/300),7.67％(23/300),56.00％ (168/300),0.67％ (2/300),respectively.After image review revised,the review rate was 8.67％ (26/300).ConclusionThe review rules established by our research for Urinalysis Work Station can find the abnormal urine samples effectively and exactly and can reduce the workload significantly.(Chin J Lab Med,2012,35:810-814)

Objective To establish the proper review rules for the microscopic screening of urine analyzed by UF-1000i automatic urinalysis work station (composed of UF-1000i urine flow cytometer and AX-4030 urine dry chemical analyzer).Methods A total of 2 839 random urine samples were collected at Chinese People′s Liberation Army General Hospital from September 2009 to February 2010, and were analyzed using UF-1000i urinalysis work station.The parameters obtained from UF-1000i and AX-4030 included RBC, WBC, CAST and ERY, LEU, PRO.After analysis by urinalysis work station, each urine sample was examined microscopically by two technologists using double-blind method.The average results got from the two technologists were regarded as the judging criterion.Based on the criterion, the review rules for the 2 839 urine samples tested by urinalysis work station were created and adjusted, and the true positive rate, false positive rate, true negative rate, false negative rate and review rate of these review rules were calculated.After that, 299 randomly selected urine samples were tested to validate these review rules.Omission diagnostic rate and review rate were used to assess the clinical practicability of the review rules.Results Thirty seven rules for microscopic review and twenty seven rules without further microscopic examination were set up based on six parameters using UriAccess 3.0 Software.The microscopic examination result was taken as the judging criterion, the consistency rate of these rules was 81.11%(2 311/2 839), the true positive rate was 40.51%(1 150/2 839), the false positive rate was 16.17%(459/2 839), the true negative rate was 41.00%(1 164/2 839), the false negative rate(omission diagnostic rate) was 2.43%(69/2 839) and the review rate was 18.28% (519/2 839).Additional 299 urine samples were assayed using UriAccess3.0 software to further verify these review rules.The consistency rate was 82.27%(246/299), the true positive rate was 36.12%(108/299), the false positive rate was 16.39%(49/299), the true negative rate was 46.15%(138/299), the false negative rate(omission diagnostic rate) was 1.34%(4/299), the review rate was 19.06%(57/299). The 4 false negative samples selected by these review rules did not come from the nephropathy department or the urology department.Microscopic results of RBC and WBC form these 4 samples ranged 3-8 cells/HP. Thus, these review rules could avoid the missed diagnosis of those patients with severe renal dysfunction.Conclusion The review rules established from this study for the UF-1000i urinalysis work station can effectively detect abnormal urine samples and improve the efficiency and the quality of urinalysis in routine clinical practice.
