Objective The international multidisciplinary lung adenocarcinoma classification was published by IASLC/ ATS/ERS in 2011.This study aimed to explore the clinicopathologic characteristics of lung adenocarcinoma based on IASLC/ATS/ERS classification and validate its clinical diagnostic and therapeutic value.Methods 2 056 cases of surgical resection from Shanghai Chest Hospital were classified according to the new classification and clinical information were retrospectively reviewed.The clinicopathologic characteristics based on new classification were analyzed statistically.Results Our data indicated that women were in high risk of lung adenocarcinoma; The average age of onset was 59-year-old; the female patients were younger than the male patients (58.7 years vs 60.2 years,P ＜ 0.01) ; Average tumor diameter was 2.6 centimeter; right lung was more popular than left and superior lobe than the inferior one.Acinar predominant subtype and papillary predominant subtype were frequently observed.Micropapillary predominant subtype and solid predominant subtype were identified to be more aggressive than other histopathologic subtypes.Most patients were classified as stage Ⅰ(71.7％),which were predominantly stage Ⅰa (53.1％).Conclusion The new classification is superior to reflect the clinicopathologic characteristics of lung adenocarcinoma and satisfy clinical needs,especially contributing to change and update the surgical strategy of early stage lung adenocarcinoma.

ObjectiveTo assess the value of transvalvular pressure gradient (TPG) by use of realtime color Doppler echocardiography in percutaneous balloon pulmonary valvuloplasty (PBPV).Methods Patients with pulmonic stenosis (80 cases) were performed by PBPV,in which the pilmonic annular diameter and TPG were measured by using of 2-D and color Doppler echocardiography in the different periods of this operation.Results The pilmonic annular diameter was not significantly difference by intraoperative echocardiography and radiography measurement (t =2.013,P ＞ 0.05).And pressure measurement by catheterization pre- and post-dilatation was not markedly significant ( t =1.258,P ＞0.05).However,TPG in patients with the different degree of pulmonic stenosis were decreased significantly ( P ＜0.01).PBPV treatments in the mild pulmonic stenosis for twice got an excellent effect according to operation criteria,but PBPV treatment in patients with the moderate and severe pulmonic stenosis need to be done for three times.ConclusionsReal-time color Doppler echocardiography is an effective way and plays a guiding role in PBPV.

Objective To explore the rationality of correcting urinary iodine (UI) concentration by using urine specific gravity (U-SG).Methods Weighing method and refractometer method were used respectively to measure specific gravity of 10-30 g/L mass concentration of different inorganic salts (sodium chloride,sodium sulfate,ammonium biphosphate) and organic matters(urea,glucose,glycine) aqueous solution,and urine plus 10-30 g/L sodium chloride or urea.UI concentrations in urine samples of 27 pregnant women respectively were expressed by direct method,weighing method U-SG correction and refractometer method U-SG correction.One random urine sample was collected for six batches in different seasons from children aged 8-10 and pregnant women for determination of U-SG and UI concentration.UI concentration was determined by arsenic cerium catalytic spectrophotometry (WS/T 107-2006).Results ①Measured by weighing method,specific gravity of inorganic salt (sodium chloride,sodium sulfate,ammonium biphosphate) aqueous solution was significantly greater than that of organic matters (urea,glucose,glycine) aqueous solution which had the same mass concentration.The specific gravity of 10 g/L sodium chloride aqueous solution was 1.008,and that of 30 g/L urea solution was 1.006.②Measured by weighing method,10 g/L sodium chloride was added to 3 urine samples separately.Accordingly the increases of USG were 0.006,0.008 and 0.007,respectively.Otherwise,the increases of U-SG were 0.003,0.002 and 0.004,respectively,when adding 10 g/L urea.~he median results of UI concentrations in urine samples from 27 pregnant women were 106.4,165.2 and 211.8 μg/L,respectively,expressing obtained by direct method,weighing method USG correction and refractometer method U-SG correction.④The determination results of six batches urine collected from children aged 8-10 in different seasons,the median results of U-SG measured by refractometer method were 1.019 0-1.021 2,the median UI concentration results obtained by direct method and refractometer method U-SG correction were 134.5-181.7 μg/L and 157.7-190.4 μg/L.The determination results of six batches urine samples of pregnant women in different seasons,the median results of U-SG measured by refractometer method were 1.013 4 -1.017 1,the median UI concentration results obtained by direct method and refractometer method U-SG correction were 96.2-138.9 μg/L and 135.2-181.6 μg/L.Conclusions The change of sodium chloride concentration in urine is the most important reason for the change of U-SG.In China,the main source of UI is the intake of edible iodized salt.Iodized salt intakes directly affect the U-SG and UI concentration.If the U-SG is used to correct the UI concentration,there will be a phenomena that the lower intake of iodized salt the lower U-SG.So the UI concentration was falsely increased significantly after correction.Conversely higher intakes of iodized salt caused higher U-SG.The UI concentration was falsely reduced significantly after correction.Therefore,U-SG cannot be used to correct the UI concentration.

Objective This study is about to detect the KCNJ5 gene variations in aldosterone-producing adenoma (APA) with primary hyperaldosteronism (PA),and to investigate the association of the KCNJ5 gene missense mutations with APA and PA.Methods A total of 46 APA tumors and their clinical characteristics were collected from Hypertension Center of the People's Hospital of Xinjiang Uygur Autonomous Region,and all the tumors were confirmed by pathology.All the samples of the coding region segments of KCNJ5 were detected by PCR and direct DNA sequencing to compare the different missense mutations in the tumor cells and peripheral blood cells and to analyze the association between the genotype and phenotype.Results Three missense mutations were found in 46 patients with APA:c.451G ＞ C/A (p.G151R) (5/46),c.503T ＞ G (p.L168R) (4/46),c.830T ＞ A (p.S209T) (12/46).S209T,as an unreported somatic mutation was observed.There were no missense mutations detected in the peripheral blood.Sex,age,systolic blood pressure,diastolic blood pressure,duration of hypertension,plasma potassium,urine potassium,aldosterone,plasma renin activity,aldosterone,and plasma renin activity ratio,as well as the rate of positive family history were compared between the mutants and wild-types.Systolic blood pressure and plasma potassium level among G151 R,L168R,and S209T had statistical differences.Systolic blood pressure in G151R was significantly higher than the other two groups,while the plasma potassium level was significantly lower than the other groups.Conclusions Three missense mutations were found in 46 patients with APA.The subjects with mutations had more serious condition than those without mutations after comparing their clinical phenotype.Besides,other different subtypes may exist in PA.

Objective To evaluate the efficacy of different treatment regimens for children with acute promye-locytic leukemia (APL)with positive PML -RARa fusion gene.Methods Thirty -two newly diagnosed APL patients were included in this study,treated either with all -trans -retinoic acid (ATRA)and chemotherapy (CT)(group A) or with ATRA and arsenic trioxide (ATO)(group B).Clinical situation and clinical efficacy were analyzed in patients in different groups.They were also separated into low risk group,intermediate risk group and high risk group according to different risk criteria.Clinical characteristics,complete remission,long -time survival and urine arsenic concentra-tion were analyzed and compared.Results (1 )Fourteen of 1 5 patients (93.3%)in group A achieved hematological complete remission (HCR)with a median time of 38 days (28 -63 days).Sixteen of 1 7 patients (94.1 %)in group B achieved HCR with a median time of 29 days (1 0 -42 days),which was significantly shorter than group A,and there was a significant difference between 2 groups(t =3.53,P =0.002).(2)The 5 -year event -free survival (EFS)of group A and group B was (60.0 ±1 2.6)% and (81 .9 ±9.5)%,respectively;the 5 -year EFS of group B was almost 20% higher than group A;while there was no significant difference between the 2 groups(χ2 =1 .1 5,P =0.28).The 5 -year overall survival (OS)of group A and group B was (72.2 ±1 1 .9)% and (94.1 ±5.7)%,respectively,the 5 -year OS of group B was almost 20% higher than group A;while there was no significant difference between the 2 groups(χ2 =2.88,P =0.1 6).(3)The 5 -year EFS of low plus intermediate group and high risk group patients was (74.0 ±1 0.1 )% and (64.8 ±1 4.3)%,the 5 -year EFS of low plus intermediate group was almost 1 0% higher than high risk group,but there was no significant difference between the 2 groups(χ2 =0.1 4,P =0.71 ).The 5 -year OS of low plus intermediate group and high risk group patients was (84.7 ±8.1 )% and (71 .3 ±1 4.1 )%,the 5 -year OS of low plus intermediate group was almost 1 0% higher than high risk group,while there was no significant difference be-tween the 2 groups(χ2 =0.36,P =0.55).(4)ATO related side effects were mild,including abnormal liver tests and e-lectrocardiogram,but were invertible after supportive therapy.At the end of each chemotherapy course,the urine arsenic concentration remained low and no chronic arsenic toxicity or second malignancies were found during the follow -up period.Conclusions The ATRA plus ATO regimen is a promising and better treatment for childhood APL with positive PML -RARa fusion gene compared with conventional chemotherapy.It was necessary to take risk stratification in APL patients.

The mechanism of chromium accumulation and microstructure transformation of the fused yeast were studied in this paper.The result showed that the process of Cr6+ reduction and adsorption was accom-panied by the H+ consumption.The main adsorptive groups on the strain surface included amino,hydroxyl,phosphate group and amide,among which phosphate group played vital role in the chromium accumulation.The removal rate of chromium and reduction rate of hexavalent chromium declined 70% and 46%,respec-tively,when phosphate group was masked.During the adsorption process the chromium ions complexed on the surface of fused yeast was transported into the cell wall and combined with inclusion to form steady spe-cies and this took 90 min to reach the equilibrium.The biosorption and reduction of Cr on the cell surface would alter microstructure of cell surface,reduce cell membrane potential and increase cell membrane per-meability.
