Sepsis has relatively high morbidity and mortality in patients at intensive care unit (ICU). With the study of sepsis having continued to develop in recent years, the defects existing in this research have unceasingly exposed. Because the lack of design process of international standardized clinical randomized controlled trials (RCT) for septic patients, the situation of incomplete data record exists in these clinical studies, that may further affect the interpretation of the research results, therefore it is in urgent need to have an international standardized RCT design process for septic patients.

Objective To observe normal range based on normal adult echocardiography with data mining retrospectively.Methods Analyzed the echocardiography data of 15 553 patients who came to Peking university People's Hospital from Nov 2012 to Nov 2014 without obvious abnormalities of cardiac structure and function.The reference range of 15 parameters were calculated and analyzed in correlation with gender,age and other factors for each group.Results The reference ranges of basic measurement parameters in two-dimensional echocardiography:main pulmonary artery diameter(MPA) (2.14 ± 0.22)cm,diameter of ascending aorta (asc Aorta) (2.87 ± 0.35) cm;The reference ranges of basic measurement parameters in M-mode echocardiography:aortic root diameter (Ao root diam) (2.82 ± 0.35) cm,left atrial dimension (LA dimension) (3.14 ± 0.37) cm,interventricular septal end-diastole thickness (Ⅳsd) (0.86 ±0.12)cm,left ventricular internal diameter at end-diastole (LVIDd)(4.67 ± 0.41)cm,left ventricular internal diameter at end-systole (LVIDs) (2.83 ± 0.34) cm,left ventricular posterior wall end-diastolic thickness(LVPWd) (0.85 ± 0.12) cm,end diastolic volume (EDV) (101.21 ± 19.83) ml,end-systole volume (ESV) (31.09 ± 9.07) ml,ejection fraction (EF) (69.55 ± 5.70) ％;The reference ranges of basic measurement parameters in pulsed doppler echocardiography:mitral A wave velocity (MVA) (73.14 ±16.42) cm/s,mitral E wave velocity(MVE) (84.18 ± 16.17) cm/s,E/A (1.21 ± 0.35),aortic peak velocity (Ao V2 max) (124.95 ± 19.87) cm/s.The measured parameters of males were higher than those of females and value of measured was increased with age for example measured parameters in LVIDd (r =0.225,P =0.00),IVSd(r =0.216,P =0.00),LA dimension (r =0.231,P =0.00) and E/A(r =0.212,P =0.00),with age were positive correlated.The range of 15 parameters in this study and the ASE 2015 guide are similar but have slightly different,such as this research shows that men's left ventricular end-diastolic diameter (4.77 ±0.41) cm,the ASE recommend (5.02 ±0.41) cm which is smaller than the result of this study.And this study for women (4.60 ± 0.40) cm is higher than the ASE recommended (4.50 + 0.36)cm.Conclusions Based on preliminary analysis of large data from normal adult echocardiography,the rang of measured values could be used as a normal reference value of echocardiographyfor routine practice in China.

Objective To investigate the influence of thrombus aspiration on ventricular remodeling of patients with ST?segment elevation type of myocardial infarction ( STEMI ) who underwent emergency percutaneous coronary intervention ( PCI) and its predicative value for patients′ prognosis. Methods Three hundred and eight patients who were diagnosed with STEMI line emergency PCI and hospitalized in the Cardiology Department of Jinghai Clinical College of Medical University of Tianjin from March 2011 to March 2014 were retrospective analyzed, including 152 patients received thrombus aspiration during primary PCI as thrombus aspiration group,and the remaining 156 patients without thrombus aspiration as control group. Indexes of myocardial perfusion levels such as ST?segment resolution 2 hours after PCI and TIMI myocardial perfusion grade were measured in all patients. All patients accepted echocardiography examinations to detect left ventricular end diastolic diameter(LVED) and left ventricular ejection fraction(LVEF) 10 days after PCI. The indexes differences of the two groups,secondary end points major cardiac adverse events(MACE) at 6 months were compared. Results There was no statistical difference between the ratio of two groups for ST segment fell more than 50%( 78. 9%( 120/152) vs. 71. 2%( 111/156) ,χ2=0. 428,P=0. 669) . But for ST segment fell more than 70%,the ratio of the thrombus aspiration group was significantly higher than that in the control group ( 73. 7%( 112/152 ) vs. 47. 4% ( 74/156 ) , χ2 = 4. 701, P = 0. 001 ) . Two groups of patients were treated by echocardiography 10 days after PCI,showed the LVED in the thrombus aspiration group was lower than that in the control group((50. 2±4. 7) mm vs. (51. 6±4. 6) mm,t=2. 642,P=0. 008),while the LVEF value was higher than that in the control group((56. 9±4. 9)% vs. (49. 4±4. 2)%,t=14. 434,P=0. 001). Recurrent angina pectoris decreased significantly in the thrombus aspiration group at 6 months ( 4. 61% ( 7/152 ) vs. 10. 90%(17/156),χ2=2. 056,P=0. 040). Conclusion STEMI patients adopt thrombus aspiration that undergoing emergency PCI,not only can improve myocardial reperfusion,especially microcirculation reperfusion, but also can improve the left ventricular systolic function and the prognosis of patients.

Objective To investigate the iodine nutritional status of the crowd that did not participate in the iodine deficiency disorders (IDD) survey in iodine deficiency areas in Jiangsu Province so as to provide a basis for prevention and control of IDD.Methods Eight to ten years old children were chosen from the counties(cities,districts) of Jiangsu Province that did not participate in the IDD survey and urine samples of students and salt samples of their families were researched.In each county (city,district) one township (street) was selected according to 5 directions of east,south,west,north,center; in each township one primary school was selected and in each primary school 20 children aged 8-10 were chosen half of the male and female,to collect their urine samples and salt samples at their families.Urinary iodine was measured using arsenic cerium catalytic spectrophotometric method (WS/T 107-2006),and salt iodine was measured using direct titration of universal test method in salt industry (GB/T 13025.7-1999).Iodine nutrition criterion of international health organization recommended staindard:children urinary iodine ＜ 100 μg/L as iodine deficiency,100-199 μg/L as iodine appropriate,200-299 μg/L as iodine more than appropriate,≥ 300 μg/L as iodine excess.Results A total of 7 523 urinary samples of 8-10 years old children were collected from 76 iodine deficiency counties (cities,districts),and the median of urinary iodine was 235.0 μg/L.In all investigated counties (cities,districts),the medians of urinary iodine of 22 counties(cities,districts) were 100-199 μg/L,42 counties(cities,districts) were 200-299 μg/L,and 12 counties (cities,districts) were ≥300 μg/L.A total of 7 523 salt samples were collected,and the median of salt iodine was 29.68 mg/kg; Taizhou City had the highest salt iodine median,which was 31.43 mg/kg; and Lianyungang City,the lowest,25.11 mg/kg.The coverage rate of iodized salt was 98.6％(7 417/7 523); iodized salt qualification rate was 98.6％ (7 312/7 417); and consuming rate of qualified iodized salt was 97.2％(7 312/7 523) in 76 iodine deficiency counties (cities,districts).Conclusions The progress in prevention and control of IDD in iodine-deficient areas that did not participate in IDD survey in the past is good in Jiangsu Province; the overall level of iodine nutrition of whole population is adequate.But the median of urinary iodine in some counties (cities,districts) is at a higher level.

OBJECTIVETo investigate the capability of semi-quantitative and quantitative parameters of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) to predict the response to concurrent chemoradiotherapy( CCRT) in patients with non-small cell lung cancer (NSCLC).

METHODSA total of 24 patients with stage III or IIIB NSCLC, who underwent 3.0T DCE-MRI before CCRT, were enrolled in this study. Semi-quantitative and quantitative parameters were calculated by Funtool and Omnikinetics software. The relationship between these obtained parameters and tumor response was evaluated by Spearmen' s correlation analysis. The patients were classified into two groups according to the tumor regression rate after treatment, as response group (group A) and non-response group ( group B). Mann-Whitney U test was used to compare the parameters of responders and non-responders. The value of the parameters on predicting response was calculated by receiver operating characteristic curve (ROC).

RESULTSThe tumor regression rate after treatment was negatively correlated with time to peak (TTP) and the extravascular-extracellular volume fraction (Ve), and was positively correlated with signal enhancement ratio (SERmax) and volume transfer constant (Ktrans) (P < 0.05 for all). Statistical significant differences were found between group A and group B both in semi-quantitative and quantitative parameters (P < 0.05). Group A had a lower TTP value [(34.66 ± 16.37) s vs. (44.09 ± 17.41) s] and Ve value [(0.19 ± 0.03) vs. (0.25 ± 0.05)] than group B, whereas group A had a higher SERmax [(166.50 ± 44.95)% vs. (113.57 ± 46.62)%] and Ktrans [(0.41 ± 0.17) min(-1) vs. (0.28 ± 0.12) min(-1)] than group B (P < 0.05 for all). The ROC analysis indicated that when setting the threshold of Ve on ≤ 0.21 for predicting response, the specificity, sensitivity and accuracy were 85.7%, 80.0% and 83.3%, respectively, with an area under curve of 0.875 (P < 0.001).

CONCLUSIONSBoth the semi-quantitative and quantitative DCE-MRI parameters are helpful for predicting the response after CCRT of NSCLC. Quantitative parameters seem to be more meaningful than semi-quantitative parameters.

Objective To introduce clinical application of retrograde medial pedicled skin flap of the leg to repair the plantar cutaneous deficiency. Methods From January 2002 to May 2008, in our hospital we adopted retrograde medial pedicled skin flap to renovate 12 cases of plantar cutaneous deficiency. The size of the skin flaps ranged from 10 cm× 7 cm to 13 cm × 12 cm. Results Ten cases of retrograde medial pedicled skin flap were survived, the rest had partial necrosis because of distal blood flow obstacle. One was cured by changing dressings; the other was repaired by secondary operation. Morphology and function of soft tissue defects were renovated well with 6-18 months follow-up. Conclusion This operation is an effective and reliable technique for plantar cutaneous deficiency.

Objective To explore the effect of prevention and treatment of external application of Algoplaque for controlling phlebitis caused by peripheral indewelling needle in vein for patients. Methods This research was divided into two parts,prevention and treatment. As for prevention research,patients were randomly divided into the experimental and the control groups,each group included 30 patients. In the experimental group,we applied directly external application of Algoplaque at the upper of needle puncture site of the vein and nearby the eye. In the control group,we applied the film directly to fix the indwelling needle. As for the treatment research, it was carried out in patients with occurred phlebitis, who were randomly divided into two groups,the experimental group included 30 cases of patients and the control group included 28 cases of patients. Observation time was one to five days. Results The incidence of phlebitis in the experimental group of prevention research was 23%, in the control group it was 90%. The incidence of phlebitis in the experimental group was significantly lower than that of the control group. The effective rate in the experimental group of treatment research was 96.7% and it was 67.9% in the control group. The difference was very significant. Conclusions External application of Algoplaque can effectively control phlebitis caused by peripheral indewelling needle in vein.
