Objective To evaluate the reliability of transpulmonary thermodilution technique,for the quantification of extravascular lung water.Method Eighteen dogs were randomly divided into 3 groups:normal group(n=6),ALIp(acute lung injury caused by pulmonary monary origin causes)group(n=6)and a ALIexp(acute lung injury caused by extra-pulmonary origin causes)(n=6).ALI_(exp)model was prepared by intravenous injection of injection of oleie acid.ALI_p model was made by inhalation of detergent.Extravascular lung water(EVLW)was measured by PiCCO monitor(PULSION,Germany)before and immediately after the intratracheal introduction of normal saline into the alveoh of lungs of normal and ALI dogs.Results The EVLW of the normal group was(254.5?13.0)mL.The volume of the normal between pre-and postinstillation(?EVLW) was approximate to the volume of normal saline instilled with a good correlation(r=0.986,P

Objective To investigate the incidence and distribution of aberrational karyotype in acute myeloid leukemia (AML), and study the significance of the grouping by Southwest Oncology Group/Eastern Cooperative Oncology Group (SWOG/ECOG) in the prognosis of AML Methods The chromosome was prepared with brief culture of bone marrow, and the karyotype was analysed by G banding technique. All the patients were grouped according to the criterion of SWOG/ECOG, and the survival function of different groups was observed by the Kaplan-Meier method.Results 56 (67.47 %) out of 83 patients had clonal chromosome aberrations. Among those 56 patients, AML with translocation (15;17) and with translocation (8;21) presented in 30 patients(53.57 %), and the other kinds of aberrational karyotypes shared the left proportion. Among the 74 followed-up patients, 42 patients were dead. Among three groups with favorable, intermediate and adverse prognosis respectively, there is a significant difference (P <0.001). The complete remission rate of favorable group is higher than that of both intermediate and adverse (P <0.05). There is no difference between intermediate and adverse groups(P>0.05). Conclusion Cytogenetic aberration is one of the important factors affecting the effect on prognosis. The criterion of SWOG/ECOG can predict prognosis objectively.

Objective To analyze the frequency of NPM1 mutation in de novo acute myeloid leukemia (AML) patients and the relationship between NPM1 mutation and chromosome alterations,as well as FAB subgroups,and to analyze the mutation type.MethodsA total of 99 de novo AML patients from 2004 to 2010 in China-Japan Friendship Hospital were studied.Genomic DNA was amplified by polymerase chain reaction (PCR),denaturing polyacrylamide gel electrophoresis (PAGE) and capillary electrophoresis were used to detect the mutation of NPM1 gene in 99 AML patients,and karyotyping was performed in 72 AML patients by G banding techniques.DNA sequences analysis of NPM1 mutation was performed on 10 patients.Chi-square test was used to compare the frequencies of NPM1 mutation among the different subgroups,and McNemar's test was used to compare the different rates between denaturing PAGE and capillary electrophoresis.ResultsThe frequencies of NPM1 mutations were detected in 15％ (15/99) of AML patients with capillary electrophoresis and 11％ (11/99 ) with denaturing PAGE(x2 =2.25,P ＞0.05 ).The NPM1 was at different rates in M2(27％,8/30),M5(32％,6/19),M6( 13％,1/8),respectively (x2 =1.06,P ＞ 0.05 ),and not detected in the other subgroups.NPM1 mutation in patients with normal karyotype(26％ ) was more prevalent than patients with abnormal karyotype (4％) (x2 =5.61,P ＜ 0.05)All of the 10 patients were of A type ( c.860_863dupTCTG).The C-terminal portion of the NPM protein by replacing the last seven amino acids(WQWRKSL) with 11 residues (CLAVEEVSLRK).Two intronic deletions were novel,one case was IVS10-18_-15delCTTT,the other was IVS10-17_-15delTTT.Conclusions NPM1 mutations represents a common genetic abnormality in AML patients,and NPM1 mutation in patients with normal karyotype is higher than patients with abnormal karyotype.Two new intronic deletion mutations are identified.

Objective To explore the clinical value of endoscopic ultrasonography (EUS) examination before esophageal achalasia (EA) patients treated by peroral endoscopic myotomy (POEM).Methods From August 2011 to November 2011,esophageal EUS examination was conducted in 34 EA patients scheduled for POEM treatment (EA group) and 30 cases accepted gastric EUS examination (control group) at endoscopic center,Zhongshan Hospital,Fudan University.The thickness of muscularis propria layer and the circular muscle layer was measured at cardia,5 cm,10 cm and 15 cm above cardia,and the proportion of circular muscle layer was calculated.The differences in groups and between groups were compared.The correlation between muscle thickness and complication after POEM treatment was analyzed.The data were analyzed by t test.Results There was no difference between EA group and control group in the thickness of the muscularis propria layer at same part (at cardia,5 cm,10 cm and 15 cm above cardia,t=1.210,1.116,0 and 0.292respectively; all P＞0.05 respectively).The thickness of the circular muscle layer of EA group at cardia,5 cm,10 cm and 15 cm above cardia was (1.72±0.49) mm,(1.86±0.81) mm,(1.56±0.47) mm and (1.41±0.48) mm respectively,those of control group was (1.06±0.50) mm,(1.40±0.33) mm,(1.05±0.37) mm and (0.78±0.12) mm respectively.At same part,the thickness of the circular muscle layer of EA group was significantly thicker than that of the control group (t =5.326,2.903,4.778 and 6.993 respectively,all P＜0.05).After POEM treatment,complication was high in EA cases with the thickness of muscularis propria layer less than 2 mm.Conclusion Before POEM treatment,EUS examination for EA patients has certain guiding significance.

Objective:To compare three nutritional screening tools in predicting dialysis-related pro tein-energy wasting(PEW) among maintenance hemodialysis(MHD) patients and to find a more rapid,accurate,and feasible screening tool.Methods:The nutrtional risk screening 62002 (NRS 2002),7-point subjective global assessment(SGA) and malnutrition inflammation scores (MIS) were compared among 205 MHD patients.Correlations between the serum biochemistry,anthropometry and different screening tools were analyzed,and comparisons were made with established guidelines by International Society of Renal Nutrition and Metabolism (ISRNM) for PEW.Results:A total of 31.2％ of HD patients had PEW by ISRNM criteria,whilst using NRS 2002,7-point SGA and MIS,58％,40.8％ and 46.8％ of MHD patients exhibited PEW respectively.The results of three screening tools were closely related to those by serum biochemistry and anthropometry (P ＜ 0.05),but the composite correlation coefficient between the screening tools for PEW and the objective nutritional index commonly used was higher in NRS 2002(r =0.787,P ＜ 0.001) than in 7-Point SGA or MIS.NRS 2002 had higher sensitivity and accuracy values (87.5％ and 59.1％,respectively) in MHD Patients.Conclusion:MIS,7-PointSGA and NRS 2002 are valid tools for nutrition screening of dialysis patients,and NRS 2002 may be the best one.
