Purpose::The toughest challenge in pedestrian traffic accident identification lies in ascertaining injury manners. This study aimed to systematically simulate and parameterize 3 types of craniocerebral injury including impact injury, fall injury, and run-over injury, to compare the injury response outcomes of different injury manners.Methods::Based on the total human model for safety (THUMS) and its enhanced human model THUMS-hollow structures, a total of 84 simulations with 3 injury manners, different loading directions, and loading velocities were conducted. Von Mises stress, intracranial pressure, maximum principal strain, cumulative strain damage measure, shear stress, and cranial strain were employed to analyze the injury response of all areas of the brain. To examine the association between injury conditions and injury consequences, correlation analysis, principal component analysis, linear regression, and stepwise linear regression were utilized.Results::There is a significant correlation observed between each criterion of skull and brain injury ( p < 0.01 in all Pearson correlation analysis results). A 2-phase increase of cranio-cerebral stress and strain as impact speed increases. In high-speed impact (> 40 km/h), the Von Mises stress on the skull was with a high possibility exceed the threshold for skull fracture (100 MPa). When falling and making temporal and occipital contact with the ground, the opposite side of the impacted area experiences higher frequency stress concentration than contact at other conditions. Run-over injuries tend to have a more comprehensive craniocerebral injury, with greater overall deformation due to more adequate kinetic energy conduction. The mean value of maximum principal strain of brain and Von Mises stress of cranium at run-over condition are 1.39 and 403.8 MPa, while they were 1.31, 94.11 MPa and 0.64, 120.5 MPa for the impact and fall conditions, respectively. The impact velocity also plays a significant role in craniocerebral injury in impact and fall loading conditions (the p of all F-test < 0.05). A regression equation of the craniocerebral injury manners in pedestrian accidents was established. Conclusion::The study distinguished the craniocerebral injuries caused in different manners, elucidated the biomechanical mechanisms of craniocerebral injury, and provided a biomechanical foundation for the identification of craniocerebral injury in legal contexts.

Chrysanthemi Indici Flos(CIF), the capitulum of Chrysanthemum indicum, is widely used in proprietary Chinese medicine and daily chemical products. At present, CIF is mainly produced from wild resources and rarely cultivated. This study aims to reveal the correlations between linarin content in CIF and climatic factors in different habitats, and provide a theoretical basis for suitable zoning and rational production of medicinal materials. The content of linarin in CIF was determined by HPLC. Grey relational analysis and Pearson correlation analysis were carried out for linarin content with climatic factors. The results showed that the content of linarin in CIF was significantly different among different habitats. The grey relational degrees of climatic factors with linarin content was in an order of average annual precipitation>annual average sunshine hours>annual average temperature>longitude>annual frost-free period>latitude>altitude. Longitude, annual average temperature and average annual precipitation had significantly positive correlations with the content of linarin in CIF, whereas latitude and altitude showed negative correlations with it. The annual frost-free period and annual average sunshine hours had no significant correlation with the content of linarin in CIF. The content of linarin in CIF varied significantly in different habitats. High longitude, low latitude, low altitude, high annual average temperature and high annual average precipitation could be used as indicators for the habitats of high-quality Ch. indicum. This study provides a reference for selecting suitable producing areas of Ch. indicum and establishing artificial cultivation system.

A method was established for simultaneous determination of 21 active constituents including flavanols, isoflavones, flavonols, dihydroflavones, dihydroflavonols, chalcones, pterocarpan, anthocyanidins and phenolic acids in Spatholobi Caulis by ultra fast liquid chromatography with triple quadrupole linear ion trap mass spectrometry(UFLC-QTRAP-MS/MS). Then, it was employed to analyze and evaluate the dynamic accumulation of multiple bioactive constituents in Spatholobi Caulis. The chromatographic separation was performed on a XBridge®C_(18)(4.6 mm×100 mm, 3.5 μm) at 30 ℃ with a gradient elution of 0.3% formic acid aqueous solution-methanol, and the flow rate was 0.8 mL·min~(-1), using multiple-reaction monitoring(MRM) mode. A comprehensive evaluation of the multiple bioactive constituents was carried out by gray correlation analysis(GRA). The 21 target components showed good linearity(r>0.999 0) in the range of the tested concentrations. The average recovery rates of the 21 components were from 97.46% to 103.6% with relative standard deviations less than 5.0%. There were differences in the contents of 21 components in Spatholobi Caulis at diffe-rent harvest periods. Spatholobi Caulis had high quality from early November to early December, which is consistent with the local tradi-tional harvest period. This study reveals the rule of the dynamic accumulation of 21 components in Spatholobi Caulis and provides basic information for the suitable harvest time. At the same time, it provides a new method reference for the comprehensive evaluation of the internal quality of Spatholobi Caulis.

OBJECTIVE: To investigate the relationship between serum 25(OH) vitamin D and liver fat content in nonalcoholic fatty liver disease (NAFLD). METHODS: A total of 120 patients with NAFLD admitted in our hospital between June and August, 2017 were enrolled and divided into 4 groups with different serum 25 (OH) vitamin D levels: >75 nmol/L (group A, =25), 50-75 nmol/L (group B, =35), 25-50 nmol/L (group C, =32), and < 25 nmol/L (group D, =28). For all the patients, serum 25 (OH) vitamin D level was measured by ELISA, and liver fat content was determined using in-phase opposed-phase TWI sequences. The measurement data were compared among the 4 groups to assess the association between serum 25(OH) vitamin D level and liver fat content. RESULTS: The liver fat content appeared to be higher in group B (28.66±6.45%) and group C (38.74±11.47%) than in group A (22.79 ± 6.10%), but the difference was not statistically significant (>0.05); the liver fat content in group D (54.79 ± 5.28%) was significantly higher than that in the other 3 groups (>0.05). Liver fat content increased significantly as serum 25(OH) vitamin D level decreased, showing an inverse correlation between them in these patients ( < 0.05, =-0.125). CONCLUSIONS In patients with NAFLD, a decreased serum 25(OH) vitamin D level is associated with an increased liver fat content, suggesting the value of serum 25(OH) vitamin D as a predictor of NAFLD.

DNA barcode technology was used to establish a rapid identification method of Chrysanthemum indicum and Ch. morifolium based on psbA-trn H,mat K and trn L sequences. The total DNA was extracted from 21 samples collected,and the psbA-trn H,mat K,trn L sequences were amplified by PCR and sequenced. The information of these sequences were obtained. We aligned all 63 sequences,calculated the intraspecific and interspecific distances,analysed the SNPs distribution of psbA-trn H+mat K+trn L combination sequences and constructed the Neighbor-joining( NJ) Tree,using MEGA 7. 0. The results showed that the genetic distances of Ch. indicum,Ch. indicum( Juhuanao)and Ch. morifolium were overlapped. The SNPs analysis of psbA-trn H+mat K+trn L combination sequences showed that there were 19 nucleotide polymorphism loci( SNPs) and nine parsim-informative sites in the combination sequences. In addition,Ch. indicum showed more obvious sequence polymorphism than those of Ch. indicum( Juhuanao) and Ch. morifolium. The psbA-trn H sequences showed obvious length variation.The NJ Tree showed that Ch. morifolium numbered C2-C5 were clustered into a single subbranch with a bootstrap value of 62%,and Ch.morifolium could be distinguished from Ch. indicum and Ch. indicum( Juhuanao). Moreover,Ch. indicum numbered Z9 and Z10 collected from Gansu province were singly clustered into one branch with a bootstrap value of 77%. It was also found that the changes of psbA-trn H and trn L sequences information of Ch. indicum samples from the northwest were obviously related to the geography and environment. Moreover,Ch.indicum and Ch. indicum( Juhuanao) had obvious differentiation,were also regarded as the evolutionary sources of Ch. morifolium. Therefore,psbA-trn H+mat K+trn L combination sequences as DNA barcode can identify Ch. indicum and Ch. morifolium accurately and rapidly,which provides an important basis for germplasm resources identification and species identification.

DNA barcode technology was used to establish a rapid identification method of Chrysanthemum indicum based on ITS2 sequences. The total DNA was extracted from 22 collected samples,and the ITS2 sequence was amplified by PCR and sequenced,and the information of ITS2 sequence was obtained. Another 14 items of the same family or the same genus were downloaded from Gen Bank.We aligned all 36 sequences,calculated the intraspecific and interspecific distances,and constructed Neighbor Joining( NJ) phylogenetic tree,using MEGA 7. 0. The difference of the secondary structure between the ITS2 sequences was compared. The results showed that the genetic distance of Ch. indicum and Ch. morifolium was overlapped,but the maximum intraspecific distance was far less than the minimum interspecific distance between and among Ch. indicum and other species,with an obvious barcoding gap. The NJ tree showed that Ch. indicum and Ch. morifolium shared a clade,and most of Ch. morifolium with some Ch. indicum were shared a subclade,while Inula lineariifolia,Sinosenecio oldhamianus and Senecio scandens belonged to one clade separately. ITS2 secondary structures for I. lineariifolia,S. oldhamianus and S. scandens were significantly different enough to identify completely but Ch. indicum and Ch. morifolium shared two secondary structures of A and B. It was proved that Ch. indicum was one of the evolutionary sources of Ch.morifolium. Therefore ITS2 sequence as DNA barcode can identify Ch. indicum and its adulterants accurately and quickly. The study provides an important basis for Ch. indicum for the identification of germplasm resources and the safety of clinical medication.
