Seven emotions generation relates to the interaction between individual and external objective matters,which is accompanied with interaction between internal desire and external matters.The activity of seven emotions bases on essence of zang-fu organs,being regulated by five zang viscera.Heart is the upstream controller,liver is the key organ to maintain normal emotionds,spleen and stomach is the hub of emotional activities,lung is the auxiliary organ, kidney is origin of emotional generation.Five zang viscera's cooperation and interaction generate the seven emotions.

ScanningElectronMicroscopy/EnergyDispersionSpectrum(SEM/EDS),ElectronProbe Microanalysis ( EPMA ) and Optical Microscopy ( OM ) are the traditional methods for inclusion type identifying at present. The disadvantages such as inconvenient sample preprocessing, low sensitivity and time consuming limited their application. Laser-Induced Breakdown Spectroscopy ( LIBS) is not only performing in bulk analysis field but also in elemental distribution and depth profile information field, so it causes great concern in material science. In this paper, 34CrNiMo6 steel and heavy railway steel samples were analyzed by LIBS in scanning mode to characterize the inclusion type. For 34CrNiMo6 steel, 2D intensity distribution and channel combination revealed the spectra line intensity of Mn and S were abnormal high simultaneously at some region, which indicated there were some MnS inclusion existed in these samples. And for heavy railway steel, 2D distribution and channel combination revealed the spectra line intensity of Si, Ca, Mg and Al were abnormal high simultaneously at some region, showed the existence of Si-Al-Ca-Mg inclusion in these samples. The SEM/EDS analysis result of above-mentioned samples showed agreed well with LIBS.

Objective To explore the value of real-time tissue elastography (RTE) with tissue dispersion quantitative analysis technique for assessment of liver fibrosis stage.Methods 51 rats were injected 6％ thioacetamide to induce liver fibrosis model,and 9 rats were injected saline as control group.In modeling 4 weeks,8 weeks,12 weeks respectively,14 rats in group of liver fibrosis model and 3 rats in control group were randomly selected to RTE.All the rats underwent tissue dispersion quantitative analysis,to obtain 12 quantitative parameters of elasticity,which included average relative strain value (MEAN),standard deviation of relative strain value (SD),area ratio of low-strain region (％ AREA),complexity (COMP),kurtosis (KURT),skewness (SKEW),contrast (CONT),entropy (ENT),inverse difference moment (IDM),angular second moment (ASM),correlation (CORR) and liver elasticity index (LF index).Subsequently,rats were sacrificed and their livers were taken for pathology analysis.Liver fibrosis model group was divided into S0,S1,S2,S3,S4 group.The 12 quantitative parameters of elasticity were compared with each group.Results 49 rats were successfully modeled,and 42 rats were analyzed.Except COMP,KURT,CORR,the other quantitative parameters had statistically differences (P ＜ 0.05).The other 9 parameters were correlated with liver fibrosis stage.Among these parameters,MEAN,％ AREA and LF index had higher related coefficient(r =-0.831,0.882,0.866).The ROC curve was made by MEAN,LF index and ％AREA to estimate the fibrosis stage,when S≥S1,S≥S2,S≥S3,S =S4,the areas under the ROCcurve were 0.884,0.925,0.934,0.962 (MEAN);0.917,0.958,0.984,0.962 (％AREA);0.917,0.948,0.966,0.967 (LF index),respectively.Conclusions As a non-invasive examination,RTE dispersion quantitative analysis technology can be used to quantitatively assess liver fibrosis.

OBJECTIVETo offer evidences for quality control of medicinal Asteropyrum plants.

METHODPharmacognostic studies were made through field collection, market investigation, document utilization, comparative morphology and histology.

RESULTThe shape and properties, microscopic characteristics in root, rhizome, leaves were worked out.

CONCLUSIONAsteropyrum can be distinguished from close relative Coptis plants by microscopic and histology characteristics. Two species in Asteropyrum can also be identified by microscopic and histology characteristics, and the morphological and histology characteristics can be used as evidences for quality control of medicinal Asteropyrum plants.

Objective:To determine the concentration of meropenem in human serum and investigate its pharmacokinetics in Chi-nese elderly patients. Methods:Meropenem with single dose of 0. 5-1. 0 g was given to 25 elder patients by infusion administration. The concentration of meropenem was detected by an HPLC method. The pharmacokinetic parameters were calculated according to the pharmacokinetic model for adults and T>MIC was calculated by simple mathematical simulation. Results: The major pharmacokinetics parameters were as follows:Cmax of (46. 2 ± 24. 4) μg·ml-1;t1/2 of (3. 3 ± 1. 8) h,CL of (8. 7 ± 5. 0) L·h-1 ,V of (9. 8 ± 1. 3) L and AUC of (148. 2 ± 75. 4)μg·h·ml-1 . Compared with that of the healthy subjects reported in the literatures, t1/2 significantly pro-longed, V significantly decreased and AUC significantly increased (P<0. 01). Conclusion: The pharmacokinetics of meropenem in elder patients is significantly different from the healthy subjects. The clinical application should pay attention to monitoring the blood concentration of meropenem.

Objective To construct cDNA entry library and cDNA expression library of Armillifer agkistrodontis (A.) nymphs and make a preliminary immunoscreening for the cDNA expression library.Methods The nymphs were collected from the Kunming mice infected experimentally with A.agkistrodontis eggs and the total RNA were extracted from the nymphs using TRIzol Reagent.After purifying the mRNA,the synthesized cDNAs were cloned into the donor vector pDONR222 by BP reaction of Gateway technology and the recombinants were transformed into the DH10B cells by electroporation,the cDNA entry library was obtained.Next,the expression vector pDEST17 was ligated with entry clones by LR reaction,and the recombinants were transformed into the BL21 (DE3) cells.Hence,the cDNA expression library was constructed.Then,the expression library was immunoscreened with the mixed sera of mice infected with A.agkistrodontis,and the insertions of positive clones were sequenced.After that,the open reading frame(ORF) of positive slone sequence,the homology of the screened genes and their encoded proteins were analyzed by Finder and BLAST (basic local alignment search tool) program of National Center of Biotechnology Information(NCBI),and the discovered new genes were submitted into the GenBank.Besides,the physico-chemical properties,secondary structure and B cell epitopes of encoded proteins were also analyzed by bioinformatics software.Results The average titer and total clones of the cDNA entry library were 1.45 × 105 CFU/ml(colony-forming unit,CFU) and 1.74 × 106 CFU,respectively,and the range of fragment length of the inserted cDNA was between 0.2-4.0 kb,with an average of 1.4 kb.The total clones of cDNA expression library were 1.00 × 105 CFU,and the fragment length of the inserted cDNA was between 0.3-2.2 kb,with an average of 1.0 kb.Five positive clones,coded S1,S5,A1,D1 and F1,respectively,were obtained through preliminary immunoscreening.The sequence and homology of the five positive clones were sequenced and analyzed by BLAST program.No significant similarities were found in pentastomida species,which meant that they were all novel genes of A.agkistrodontis.The gene sequences were submitted to GenBank,with the accession number from JQ180451 to JQ180455.Also,results obtained by bioinformatics software showed that the predictive encoding proteins were all potential to be valuable recombinant diagnostic antigens.Conclusions The cDNA library of A.agkistrodontis nymphs is successfully constructed,and five new genes of A.agkistrodontis are discovered.The establishment of cDNA library and the discovery of the new genes will lay a foundation for further studying the gene functions and screening the immunodiagnostic antigens.
