Objective To analyze the difference of laboratory test results between early-onset and late-onset severe preeclampsia and to investigate their clinical application values.Methods Totally 108 blood samples were collected from patients with severe preeclampsia who were diagnosed according to the Diagnostic Standard of Obstetrics and Gynecology(7th Edition) published by People′s Medical Publishing House,in Shandong Provincial Hospital affiliated to Shandong University from March to November 2016,which consisted of 64 early-onset severe preeclampsia before 34 weeks gestation(early onset group) and 44 late-onset severe preeclampsia after 34 weeks gestation(late onset group).In addition,42 women with normal pregnancies as the control group were selected.General clinical data were collected,and the blood sample was analyzed through detecting Hb,PLT,fibrinogen (FIB),D-dimer,AST,ALT,urea,creatinine (Cr),uric acid,CRP,urine protein.The tested results were analyzed and compared.Flow cytometry was used to analyze the proportion of T helper 1 cells(Th1) and T helper 2 cells(Th2),and the ratio of Th1/Th2 was also calculated.All data and F test were performed by use of statistical software SPSS19.0.Results The pre-pregnancy body mass index(29.55±4.49,30.66±5.13,26.62±3.17,F=9.829,P<0.05),diastolic blood pressure[(105.17±14.46)mmHg(1 mmHg=0.133 kPa),(99.80±12.56)mmHg,(74.36±8.42)mmHg,F=82.088,P<0.05],Hb[(123.22±14.38)g/L,(117.03±16.48)g/L,(112.62±11.24)g/L,F=7.133,P<0.05],urea[(6.56±2.36)mmol/L,(4.51±1.35)mmol/L,(3.04±0.87)mmol/L,F=51.733,P<0.05],Cr[(68.47±18.05)μmol/L,(61.37±14.37)μmol/L,(48.54±8.73)μmol/L,F=23.737,P<0.05],CRP[(7.68±8.76)mg/L,(5.88±6.03)mg/L,(3.56±2.41)mg/L,F=4.735,P<0.05],urine protein[(3.66±0.76)g/L,(2.20±1.05)g/L,(0.19±0.40)g/L,F=249.714,P<0.05]had a statistically significant difference among the early-onset,late-onset and control groups.The flow cytometry results demonstrated that the proportion of Th1 in early-onset group(19.83±3.04)was higher than that in both late-onset (14.49±2.79)and control groups(11.78±1.17),on the contrary,the result of Th2 was much lower(early-onset:1.02±0.12,late-onset: 1.11±0.12,control: 1.56±0.11),there was statistical significance among these three groups(Th1: F=135.110,P<0.05;Th2: F=293.687,P<0.05).Conclusions It′s necessary to real-time monitor the laboratory indicators,such as liver and kidney function,especially the immunologic function indicators for evaluating the disease of early-onset and late-onset severe preeclampsia and personal treatment,and for ensuring the health of mother and fetus and improving the prognostic of mother and fetus.

ObjectiveTo investigate distingwished clinical and experimental characteristics of the four main subtypes in myelodysplastic/myeloproliferative neoplasms (MDS/MPNs).MethodsMDS/MPNs 53 cases from Provincial Hospital Affiliated to Shandong University,including 24 cases CMML,13 cases aCML,12 cases JMML,4 cases MDS/MPN-U,were analyzed regarding to 2001 WHO classification.Morphology (M) of peripheral and bone marrow blood cells were observed under microscope.FCM was used in immunological(Ⅰ) analyse on blasts and myelomonocytes in peripheral blood and bone marrow.G-banding technique was used in cytogenetic (C)examination.PCR was used in molecular genetic (M) mutation detection.Numeric data,such as mean Hb,WBC,PLT et al,among several groups,were compared using Single-factor analysisof variance.Student-Newman-Keulstestwasuseincomparingmeansof two groups.Proportions,such as percentage of clinical features,immunological and cytogenetic abnormal cases among different groups,were compared using Chi-square test or Fisher exact test.Results( 1 ) In the course of MDS/MPNs,there were 46 cases (86.8% ) had paleness and fatigue 33 cases (62.5% ) had palpable spleen.JMML had most fever and enlargement of lymph node (75.0%,75.0% ),statistically distinguished from CMML ( 12.5%,12.5% ) (x2 =14.89,17.98,P < 0.05 ).(2) The hemoglobin was ( 83.1 ± 24.6 ) g/L.WBC counts were ( 19.8 ± 8.1 ) × 109/L.PLT counts were ( 158.7 ± 108.2) x 109/L.Immature neutrophils and blasts were found in peripheral blood.(3)JMML and CMML had most monocytes absolute counts among the subtypes (4.25 ±0.76) (3.62 ±0.76).(4) Almost 100% JMML had monocytes abnormalities.(5)For 15 cases were detected immunological characteres by FCM,13 cases showed abnormalities.(6)For 29 cases of MDS/MPNs had been analyzed chromosome karyotypes and 12 out of them (41.4%) were abnormal,Ph chromosomes and those AML-defining translocations were all negative,+ 8 and 7-involved- karyotypes were more frequent.(7)23 cases were detected molecular genetic features,in which were all negative.BCR/ABL1 and JAK2 V617F mutation were all negative in the 13 cases of aCML.JAK2 V617F mutation was positive in 1 case of MDS/MPN-U.ConclusionsMost MDS/MPNs had paleness and fatigue,light to mild anemia,cytosis,monocytes low grade of blast and immature neutrophils in peripheral blood with dysplasia in bone marrow.JMML seems has more severe clinical features and more distinguishing laboratory characters.Immunological abnormalities and abnormalkaryotypes are found frequently in MDS/MPNs with no statistical differences among the four subtypes.There is no specific molecular abnormals in MDS/MPNs.( Chin J Lab Med,2012,35:832-837)

<p><b>BACKGROUND AND OBJECTIVE</b>Transbronchial needle aspiration (TBNA) and endobronchial ultrasound-guided TBNA (EBUS-TBNA) have been applied to the diagnosis for mediastinal lymph nodes. The aim of this study is to evaluate the clinical value and safety of TBNA and EBUS-TBNA on hilar and mediastinal lymph nodes of lung cancer patients.</p><p><b>METHODS</b>Two hundred fifty patients with suspected lung cancer were enrolled. All petients with hilar and/or m lymphoadenopa-ediastinal thy found by CT scan received TBNA, biopsy and brushing. EBUS-TBNA was performed in 15 patients among them.</p><p><b>RESULTS</b>Lung cancer were confirmed in 180 patients by TBNA, biopsy and brushing. The positive rates were 82.86%, 51.24% and 45.45%. Fifteen patients after EBUS-TBNA had a positive rate of 91.67%.</p><p><b>CONCLUSION</b>TBNA and EBUS-TBNA were proved to be safe procedure with a high yield for the diagnosis ofhilar and mediastinal lymph nodes in lung cancer patients.</p>
