Heavy metal residue in vegetables is a big concern in the whole world.The aim of this work is to explore the effect of multivariable selection on analyzing Cd in Chinese cabbage polluted in lab by collecting the spectra of laser induced breakdown spectroscopy (LIBS) from the samples.At the same time,the actual Cd content in samples was obtained by anodic stripping voltammetry (ASV).The LIBS spectral range in partial least square (PLS) model was screened by standard normal variable transformation (SNV),first derivative (FD),second derivative (SD) and center treatment (CT) for preprocessing spectra and the optimized method was used for the analysis of interval partial least square (iPLS) and synergy interval partial least square (SiPLS).The results indicated that the method of CT was the best as a comparison with PLS,iPLS and SiPLS.And the intervals of wavelength were 214.72-215.82 nm,215.88-216.97 nm and 225.08 -226.35 nm by utilizing the optimized SiPLS.Here the root mean square error of cross validation (RMSECV) between real content and predicted ones was 1.487,the root mean squared error of prediction (RMSEP) was 1.094,the correlation coefficient (R) was 0.9942,and the average relative error (ARE) was 11.60％.The results displayed that LIBS could predict Cd in vegetables by multivariable selection of SiPLS and the accuracy could meet the requirement of rapid and green analysis of Cd in vegetables.

Objective:To investigate the effects of the Paecilomyces Lilacinuson extracellular polysaccharides on the phenotypic and maturation of murine dendritic cells. Methods: Imature DCs were induced in vitro from the murine bone marrow cells in the presence of rmGM-CSF and rmIL-4, and then they were cultured with different dosage of the extracellular polysaccharides. The morphological characterization was analyzed under microscopy. The expressions of the DCs surface costimulating factors and phagocytic function to FITC-dextran were detected by flow cytometry. The level of IL-12 secreted by DCs was observed by ELISA. At the same time the influence of DCs on the proliferation of T cells was determined by MTT. Results:Treating with the polysaccharides for 48 h could up-regulate the expression of DCs surface molecules,such as CD11c,MHCⅡ,CD80 and CD86,and the 400 μg/ml was the optimal dose,comparing with the blank control group, the difference was significant (P<0. 01), contrast to LPS control group that was not different ( P<0. 05 ) . The uptaking FITC-dextran ability of the DCs treated with 300 μg/ml and 400 μg/ml polysaccharides was significant lower than the unstimulated DCs(P<0. 05). At the same time the extract at different concentration could distinctly enhance the proliferation of T cells by DCs too. Conclusion:The extracellular polysaccharides could stimulate the maturation of dendritic cells and induce the production of mature dendritic cells.

AIM: To investigate the effects of Chinese medicine, Jinan injection, on ultrastructure and mitochondria in cultured lung cancer cell lines. METHODS: The cultured lung cancer cell lines PG and PAa were used and divided into 4 groups: control (C), cisplatin (DDP), Jinan (JA) and Jinan in combination with cisplatin (DJ), respectively. The changes of morphology and mitochondria membrane potential, intracellular Ca~(2+) and pH in every group were observed by inverted microscope and electronic microscope as well as by using flow cytometry, staining by rhodamine, Fluo-3 and BCECF, respectively. RESULTS: Degeneration cells showed chromatin condensation and peripheral congregation. In cytoplasm autophage lysosome increased and myelinoid body was seen easily. In mitochondria structure, where the space between the inner and outer membranes of these organelles expanded as the matrix was compressed. The electron-dense or swelled was observed as vacuole degeneration and its matrix showed electron-lucent. Compared to control, mitochondria membrane potential increased in every group after 24 h and 48 h treatment. DDP increased intracellular calcium ion in PG cells, however, in PAa cells, JA and DJ decreased it. Intracellular pH got lower at 24 h and higher at 48 h in PG and PAa cells. There were significance in every group vs control in PG and PAa by statistic t-test (P

BACKGROUND:Mechanical properties of the blood vessels include axial and radial tension which is important to guarantee the tissue perfusion and its pressure. OBJECTIVE:To test and analyze stretching and puncture parameters that can ful y characterize the performance of blood vessels, so as to predict the health condition of the vessels transplanted into recipients. METHODS:Mechanical properties as circumferential tension, axial tension and puncture were tested on the porcine aorta, and then pathological and staining analysis was done to explore whether freeze-dried vessels can withstand the blood pressure in al directions after transplanted into the body. RESULTS AND CONCLUSION:Specific trend on the curves of freeze-dried vessels during circumferential tension, axial tension and puncture process was closer to that of fresh vessel curves, suggesting that structural components and arrangement of the freeze-dried vessels were not changed greatly. Meanwhile, the microscopic observations of slice and tensile section were taken into account so that the reason was studied and explained for the mechanical properties of the experimental data and results. The macroscopic mechanical result was analyzed based on the change of microstructure. These findings indicate that the vacuum freeze-drying is a better method to maintain the performance of blood vessels.

Objective To evaluate the efficacy and safety of recombinant human brain natriuretic peptide (rh-BNP) combined with levosimendan on acute myocardial infarction complicated by heart failure.Methods Patients who suffered from anterior wall acute myocardial infarction (AMI) with heart failure (KillipⅡ ～ Ⅲ) within 12 to 24 hours after the onset of chest pain were randomized into two groups: the control group (n=30, receiving dobutamine and/or cedilanid) and the experimental group (n=30, receiving rh-BNP combined with levosimendan).The hemodynamics, parameters of laboratory tests and adverse events were observed before and after treatment.Results The experimental group showed that the respiratory rate (RR), heart rate (HR), systolic blood pressure (SBP), arterial blood gas oxygen saturation (SaO2), cardiac index (CI), extravascular lung water index (EVLWI) were significantly different between 2 h and sequential time points after treatment and pre-treatment (allP＜0.05).The control group showed that RR, HR, SaO2, CI, EVLWI were significantly different between 6 h and sequential time points after treatment and pre-treatment (P＜0.05 for all).There were significant differences in RR, HR, SBP, SaO2, CI, EVLWI at 2 h and 6 h after treatment between the two groups (P＜0.05 for all).Parameters of RR, HR, CI, EVLWI at 72 h after treatment had differences between the experimental group and controls.Patients in the experimental group presented larger urine volume, lower level of plasma NT-pro BNP, higher left ventricular ejection fraction (LVEF) and shorter length of stay in CCU as compared with patients in the control group (P＜0.05 for all).In adverse events monitoring in hepatic parameters, electrolyte level and coagulation function before and after treatment, there was no significant difference between the two groups.Conclusions Compared with the conventional treatment, the combination therapy with rh-BNP and levosimendon can improve the hemodynamics, increase the urine volume, decrease the level of plasma NT-proBNP and elevate LVEF significantly, so as to improve the clinical symptoms and shorten the hospital stay in patients with acute myocardial infarction complicated by heart failure.
