Objective To assess the effects of dynamic monitoring of plasma Pro-B-type Natriuretic Peptide(Pro-BNP) in the evaluation of prognostic value and myocardial dysfunction in patients with septic shock.Methods The levels of plasma Pro-BNP were tested in 102 patients with septic shock on the 1,3,and 5 days.Data on ICU mortality and 28-day mortality were collected.The patients were divided into non-dysfunction group (CI＜3.0) and cardiac dysfunction group (CI≥3.0) according to levels of hemodynamic variables ( CI level).The prognostic value of plasma Pro-BNP was analyzed.Results Plasma Pro-BNP levels on the 1,3 and 5 days in 28-day survivors have a significant declining trend [( 1649.0 ± 257.5 ) ng/L,( 1867.6 ± 291.7 ) ng/L vs.(1229.9 ± 194.5) ng/L),while plasma Pro-BNP levels in non-survivors have an increasing trend [(4128.8 ± 1051.1),( 5315.9 ± 925.4 ) vs.( 6899.9 ± 1327.9 ) ng/L].There is statistical significance of plasma Pro-BNP levels at day 1,3 and 5 for the two groups ( t=3.057,5.083,and 6.290 respectively,P＜0.01 ).The 28-day mortality and Plasma Pro-BNP levels in cardiac dysfunction group were higher than of non-dysfunction group ( 28-day mortality:62.1％ vs.20.0％;Pro-BNP1:( 1592.8 ± 362.2 )ng/L vs.( 4556.6 ±732.7 ) ng/L;Pro-BNP3:( 2933.6 ± 421.7 ) vs.( 5768.5 ± 793.7 ) ng/L,Pro-BNP5:( 3014.5 ± 587.5 ) ng/L vs.(8873.9 ± 1670.1) ng/L ( x2=20.635,P=0.000,t=3.626,3.154,3.310,P＜0.01].Pro-BNP level greater than 3053 ng/L on the 5-day was an independent prognostic indicator of 28-day mortality ( sensitivity:88.4％;specificity:91.5 ％ ).Pro-BNP level greater than 2378 ng/L on the 5-day was an independent prognostic indicator of hospital mortality ( sensitivity:84.9％;specificity:91.8％ ).In multivariate logistic regression analyses,Pro-BNP level and APACHE score were independent predictors of 28-day mortality and hospital mortality.Conclusion Plasma Pro-BNP level shows obvious significance in evaluation of sepsis-induced myocardial depression severity in patients with septic shock.Pro-BNP level in ICU at day 5 after inclusion is an independent prognostic marker of mortality in septic shock.

Objective To explore the effects of the neotype hand-arm sling on shoulder subluxation and transferring movement in hemiplegic stroke patients.Methods Thirty hemiplegic stroke survivors with shoulder subluxation and poor elbow flexor muscle tone (＜2 on the Modified Ashworth Scale).were selected and randomly divided into three groups.Group 1 was trained in static upright standing,plus 10 min of sit-to-stand training and 20 min of walking training with no support for the hemiplegic,subluxed shoulder.Group 2 did the same training using a bagtype shoulder sling,and group 3 used the neotype hand-arm sling.Index finger palpation was used to evaluate the degree of shoulder subluxation,and the Five Times Sit-to-Stand (FTSST) and Timed Up-and-Go (TUG) times for the three groups were compared.Results In the static standing training,both the bag-type sling and the neotype hand-arm sling could effectively reduce shoulder subluxation.However,after 10 min of sit-to-stand training the neotype hand-arm sling was found to be significantly superior to the bag-type shoulder sling in improving shoulder subluxation,with the latter having no effect on shoulder subluxation.In the 20 rin of walking training,the neotype hand-arm sling provided significantly more effective support than the bag-type shoulder sling,although both could support the shoulders.Those using the neotype sling had shorter FTSST times,though there were no significant differences in the average TUG times.Conclusions The neotype slings can more effectively counter shoulder subluxation in upright stance,especially during sit-to-stand maneuvers and walking.It might have positive effects on transferring ability.

Background Choroidal neovascularization (CNV) is a main cause of visual impairment in many retinal diseases.To create an ideal CNV animal model is very important for the experimental and clinical study of CNV.The assessment method of repeatable and reliable for CNV model is still seldom.Objective This experiment was to explore the label value of fluorescent antibody for visualizing and quantifying the morphologic changes associated with laser-induced CNV.Methods Laser-induced CNV models were created in 30 eyes of 15 male SPF C57BL/6J mice by Krypton red laser irradiating fundus 2 spots around the optical disc with the wavelength 647.1nm,power 260 mW,spot diameter 50μm and exposure time 0.05 seconds.The CNV was evaluated at 5 minutes,4,7,14 and 28 days after laser injury by using fundus photography and fundus fluorescein angiography (FFA),and the successful models were identified as the rupture of Bruch's membrane.The mice were then immediately sacrificed and the eyeballs were enucleated to prepare the choroidal flatmounts.The posterior eye cups were fluorescently labeled with markers of cell nuclei (DAPI,4',6'-diamino-2-phenylindole),endothelial cells (isolectin-B4),and filamentous actin (phalloidin).The CNV areas from specimens were measured by Image pro plus 6.0.Two eyes from one matched mouse without receiving photocoagulation were used as the controlls.This study followed the Standard of Association for Research in Vision and Ophthalmology.Results No any CNV was seen in photocoagulated eyes in 5 minutes and 4 days after laser irradiation.The first sign of CNV appeared at 7 days following photocoagulation.The incidence of fluorescein leakage was 76.47% (26/34),81.81% (18/22),50.00% (5/10) at 7,14 and 28 days,respectively.The fluomicroscope examination showed that in unphotocoagulated areas,retinal pigment epithelial (RPE) cells were visualized with a uniform hexagonal array.Immediately after laser exposure,a circular area devoid of fluorescent labeling was observed,indicating disruption of the choroid-Bruch membrane-RPE complex.On the fourth day,cellular debris and fragmented nuclei were presented and an autofluorescent ring was visible at the site of Bruch's membrane disruption.The number of CNV vessels increased exponentially during the next 3 days.At 7 days,a well-defined isolectin-B4 labeled CNV network was exhibited and lasted for 28 days.The CNV areas were (7.99±0.42)×103μm2,(16.89±3.77)×103μm2,(14.37±4.02)×103μm2 at 7,14 and 48 days after photocoagulation respectively,showing a significant difference among these three groups (F=17.340,P=0.000),and the CNV area was significantly increased in the photocoagulating eyes in 14 days and 28 days compared with 7 days (q=16.46,q=15.54,P＜0.01).Conclusion Fluorescent antibody labeling allows the well identification and measurement of laser-induced CNV lesions in mouse choroid/RPE flatmounts.This technique offers excellent morphologic detail and facilitates the study of critical early events in CNV.CNV complexes are labeled at an early stage,providing a more accurate preclinical evaluation of antiangiogenic molecule.

Objective:To explore the predictive value of relevant hemodynemics indexes on cardiac shock prognosis by PiCCO technology.
Methods:A total of 54 consecutive patients with cardiac shock treated in our hospital from 2012-01 to 2013-05 were studied. The patients’ general information with hempdynemics indexes as cardiac index (CI), extra vascular lung water index (EVWI), general ejection fraction (GEF), general end diastolic index (GEDI), systolic vascular resistance index (SVRI) were monitored by PiCCO technology at before and 48 hours after treatment. Based on 28 days surviving condition, the patients were divided into 2 groups:Survival group, n=28 and Death group, n=26. The levels of above indexes were compared between 2 groups and their predictive values on cardiac shock prognosis were calculated by ROC curve analysis.
Results:Compared with Death group, Survival group presented much higher CI, GEF and much lower EVWI, SVRI at before and 48 hours after treatment, P<0.05-0.01, while GEDI was similar between 2 groups, P>0.05. With 48 hours treatment, the ROC analysis showed AUCEVWI=0.846 with cut-off point at 7.5ml/kg, AUCCI=0.884 with cut-off point at 3.46 L/(min·m2) and AUCGEF=0.853 with cut-off point at 16.5%;the sensitivity and speciifcity of EVWI, CI, GEF were 79.2%and 81.0%, 82.8%and 83.0%, 74.1%and 88.7%respectively. Multivariate Logistic regression analysis indicated that CI and EVWI were the independent predictors for cardiac shock prognosis.
Conclusion:PiCCO monitoring technology may guide the balance of relevant hempdynemics indexes in patients with cardiac shock. With 48 hours treatment, the levels of CI and EVWI had predictive value for cardiac shock prognosis.

To study the pharmacokinetics of ~(131)I-Metuximab injection (Licartin) combined with transarterial chemoembolization (TACE) for treatment of hepatocellular carcinoma (HCC). MethodsLicartin (27.75 MBq/kg) and the mixture of anticancer drug and Lipiodol were sequentially administered with interval of 20 minutes to 15 patients with HCC via a transfemoral catheter.After the Licartin was administrated, the pharmacokinetic and biodistribution data were evaluated through venous blood samples,urine collections,and 4 γ-scintigraphies (SPECT) over 7 days. The pharmacokinetic parameters were determined from integration of the blood radioactivity-time curves using the SPSS 12.0 software. The tumor-no-tumor ratio (T/NT) was calculated by ROI. Absorbed doses in organ were estimated according to the medical internal radiation dose formalism. The biodistribution of licartin within patient's body at different time points was compared for various organs using analysis of variance for repeated measures, as well as the T/NT ratio. ResultsThe blood radioactivity-time curves followed the dynamics two-compartment model, with the major pharmacokinetic parameters including t_(1/2)α(1.96±1.65) h, and t_(1/2)α(19.07±5.91) h,and t_(1/2)β (57.09±10.92) h, and C_(max) 2.113×10~9min~(-1)·L~(-1), and AUC_(0-∞) 1.302×10~(11) h·min~(-1)·L~(-1), respectively. The accumulated urine radioactivity was 52.2% of administrated dosage during 144 h after administration. There were statistical significant difference of biodistribution of licartin and T/NT ratio between organs at different time points (F=6.583, P<0.01 and F=3.546, P<0.01). SPECT scans showed the significant accumulation of the radioconjugate in liver tumor and faint uptake in other organs for 14 days. Tumor-to-liver ratio decreased from 2.88±1.02 at 3 h to 1.64±0.40 at 168 h (n=7). Organ absorbed dose was (3.19±1.01) Gy in liver (n=12) and (0.55±0.09) Gy in red marrow (n=7). ConclusionLicartin combined with TACE for treatment of HCC is helpful to significantly accrete the radioconjugate in liver tumor, and protect normal organs from radiotoxictiy.
