Abstract
Abstract Objective To investigate the stability of IgE in postmortem plasma and hemolyzed samples under different storage conditions and freezing-thawing. Methods Thirty nine cardiac blood samples were collected from non-frozen corpses with the postmortem interval of less than 48 hours, including 20 plasma samples and 19 hemolyzed samples taken from whole blood. The samples were stored at -20 ℃, 4 ℃ and 25 ℃ for 28 d and at -80 ℃ for 1 year to evaluate the stability of IgE under different storage conditions. Repeated freezing-thawing treatment was conducted for 5 times to explore the stability of IgE in postmortem plasma and hemolyzed samples. IgE concentration in plasma and hemolyzed samples was detected by electroluminescence before and after treatment. Results The degradation rates of IgE in plasma samples under the three storage conditions, -20 ℃, 4 ℃ and 25 ℃ were close. After 28 d, the mean value was about 15%, the degradation speed of IgE in hemolyzed samples was faster than that of plasma under the same condition (P<0.05) and the degradation rate was faster than other two conditions under 25 ℃ (P<0.05). The differences in the concentration of plasma samples after freezing at -80 ℃ for 1 year and that before freezing had no statistical significance ( P>0.05), while the concentration of hemolyzed samples was degraded after freezing at -80 ℃ for 1 year (P<0.05). The differences between the detection results of plasma and hemolyzed samples after repeated freezing-thawing for 5 times and that before freezing-thawing showed no statistical significance ( P>0.05). Conclusion IgE has good freezing-thawing stability in postmortem plasma and hemolyzed samples. Stability of IgE is better in postmortem plasma samples than hemolyzed samples, thus it is recommended to separate plasma from postmortem blood samples as soon as possible in forensic practice.

Abstract
Abstract Objective To investigate the treatment effect of hollow fiber ultrafiltration technology on hemolytic samples and the differences between IgE concentration and serum concentration before hemolysis in ultrafiltrate. Methods The 33 postmortem blood samples of non-frozen corpses within 72 hours after death were collected, 4 mL blood was taken from each case, among which 1 mL was centrifuged to get serum, and the remaining 3 mL blood was frozen-thawed 3-5 times to cause complete hemolysis. The 2 mL hemolytic samples were processed by hollow fiber ultrafiltration to obtain ultrafiltrate. The hemoglobin concentration in serum, complete hemolytic sample and ultrafiltrate was determined by Van-Zij solution-cyanated methemoglobin assay method, and the total IgE in serum and ultrafiltrate was determined by electrochemical luminescence method. Results The hemoglobin concentration in ultrafiltrate was significantly lower than that in complete hemolytic samples (P<0.05). There was a good correlation between the total IgE detection values of ultrafiltrate and serum (r=0.984). The difference between the serum and the value of IgE in ultrafiltrate after correction had no statistical significance, and the differences between the two in positive rates had no statistical significance (P>0.05). Conclusion Ultrafiltration technology has a good treatment effect on complete hemolytic samples, and the correction value of ultrafiltrate detection is close to the serum level before hemolysis, and therefore, it can be applied to the detection of total IgE of frozen corpse hemolytic samples.

Abstract
Abstract With the rapid development of the social economy in China, the incidence of diseases caused by excessive drinking is gradually increasing as well. Alcoholic cardiomyopathy refers to long-term high intake of ethanol, and has typical dilated cardiomyopathy characteristics, such as, hemodynamic changes, symptoms, signs, and morphological features. It is a kind of cardiomyopathy that excludes other causes of dilated cardiomyopathy. Due to the lack of specific pathological changes, the forensic pathological identification of alcoholic cardiomyopathy can only be based on the patient's medical history and by ruling out other causes of cardiomyopathy. This paper reviews the pathogenesis and forensic identification of alcoholic cardiomyopathy in order to provide reference for forensic pathologists and clinicians.

Abstract
Objective: To investigate the effects of artesunate combined with bortezomib on the proliferation, apoptosis and autophagy of human acute myeloid leukemia cell lines MV4-11, and its mechanisms. Methods: MTT method was used to determine the anti-proliferation effect of different concentrations of artesunate, bortezomib and their combination on MV4-11 cells. The cell apoptosis were analyzed by flow cytometry. The expression of cleaved-Caspase-3, Bcl-2 family protein (Bcl-2, Mcl-1, Bim, Bax) and autophagy-related protein LC3B were assayed by Western blot. Results: Artesunate displayed a proliferation inhibition effect on MV4-11 with dose- and time-dependent manner, the IC(50) of artesunate on MV4-11 after 48 hours was 1.44 μg/ml. Bortezomib displayed a proliferation inhibition effect on MV4-11 with dose-dependent manner, the IC(50) of bortezomib on MV4-11 after 48 hours was 8.97 nmol/L. The combination of artesunate (0.75, 1.0 μg/ml) and Bortezomib (6, 8 nmol/L) showed higher inhibition on MV4-11 than artesunate or bortezomib alone in the same concentration gradient after 48 hours (P<0.05) . The cooperation index of the two drugs were all less than 1. The 48 h apoptotic rate of artesunate (1.5 μg/ml) on MV4-11 was (15.27±2.18) %, (19.85±3.23) % of bortezomib (8 nmol/L) , (81.67±5.96) % of combination of the two drugs, significantly higher than the single group (P<0.05) . When combination of the two drugs on MV4-11 after 24 hours, the levels of pro-apoptotic protein Bim and the cleaved activation of Caspase-3 and autophagy-related protein LC3B were up-regulated and the anti-apoptotic protein Bcl-2 expressions was down-regulated. Conclusion: Combination of artesunate with bortezomib shows a significant synergistic effects on proliferation, apoptosis and autophagy of MV4-11 cell lines, which may be associated with Bcl-2 family proteins expression.

Abstract
Because cryopreservation can effectively slow down the putrefaction and prolong the preservation time of corpses, it has become the main way of corpse preservation in China. However, it may cause a certain degree of non-specific effects on the corpses and thus interfere with forensic pathological identification. This paper summarizes relevant problems reported in domestic and foreign literature reports and practical identification, and analyzes the effects of cryopreservation on corpses from aspects of anatomical findings, histomorphology, postmortem biochemistry, and postmortem imaging, therefore to provide Chinese forensic workers assistance on problems in their practice of forensic pathology.

Abstract
Commotio cordis (CC) is the acute death caused by the cardiac rhythm disorder after a sudden blunt external force to the precordium of a healthy person without previous heart disease. As one type of violent heart damage, CC is rare with relatively small external force and sudden death, therefore causing disputes. This paper reviews the epidemiology, mechanisms and the key points in forensic identification of CC, discusses the identification and antidiastole of CC, myocardial contusion, sudden cardiac death and death from inhibition, and provides assistance to forensic pathologists to identify such causes of death.

Abstract
To investigate the roles and explore the altered expression of microRNAs (miRNAs) and mRNAs in chicken embryos in response to Newcastle disease virus (NDV) infection, deep sequencing was performed. Then, a conjoint analysis of small RNA-seq and mRNA-seq was performed to screen interactional miRNA⁻mRNA pairs during NDV infection. In total, 15 and 17 up- and downregulated miRNAs were identified that potentially targeted 4279 and 6080 mRNAs in NDV-infected chicken embryonic tissues, respectively; in addition, 595 upregulated and 480 downregulated mRNAs were identified. The conjoint analysis of the obtained data identified 1069 miRNA⁻mRNA pairs. Among these pairs, 130 pairs were related to immune or inflammatory responses. The relationship between gga-miR-203a and its target transglutaminase 2 (TGM2) was confirmed using a dual-luciferase reporter system and a real time quantitative polymerase chain reaction (RT-qPCR) assay. Overall, the discovery of miRNAs, mRNAs, and their potential pairing relationships, which may be involved in the regulation of NDV infection, will facilitate our understanding of the complex regulatory relationship between the host and the virus.

Abstract
This study aimed to determine whether abnormal apoptosis is present in acetabular cartilage in early developmental dislocations of the hip (DDH), and if so, whether it is correlated with the expression of caspase-3 and Bcl-2. DDH was induced in 24 4-week-old New Zealand white rabbits. Acetabular cartilage specimens from the experimental and control groups were stained with hematoxylin and eosin (H&E). Animals from the experimental group developed acetabular dysplasia. Apoptotic chondrocytes were observed by ultrastructural electron microscopy and H&E. TUNEL assays revealed significantly greater acetabular chondrocyte apoptosis in the treated samples as compared to the control. Significantly higher caspase-3 expression and lower Bcl-2 expression were also measured in the DDH group compared with the control. We conclude that excessive apoptosis does occur in acetabular cartilage with DDH, and is positively correlated with high caspase-3 expression as well as low Bcl-2 expression.

Background Gongylonema pulchrum (Nematoda: Gongylonematidae), a thread-like spirurid gullet worm, infects a range of mammalian definitive hosts, including cattle, pigs, equines, goats, primates and humans, and can cause gongylonemiasis. Methods In the present study, the complete mitochondrial (mt) genome of G. pulchrum was obtained using Long-range PCR and subsequent primer walking. The phylogenetic position of G. pulchrum within the Spiruromorpha was established using Bayesian analyses of the protein-coding genes at the amino acid level. Results The length of this AT-rich (75.94%) mt genome is 13,798 bp. It contains 12 protein-coding genes, two ribosomal RNA genes, 22 transfer RNA genes and one non-coding region. The gene arrangement is the same as those of Thelazia callipaeda (Thelaziidae) and Setaria digitata (Onchocercidae), but distinct from that of Heliconema longissimum (Physalopteridae). Phylogenetic analyses, based on the concatenated amino acid sequence data for all 12 protein-coding genes using Bayesian inference (BI) method, showed that G. pulchrum (Gongylonematidae) was more closely related to Spirocerca lupi (Spiruroidea) than other members of the infraorder Spiruromorpha. Conclusions The present study represents the first mt genome sequence for the family Gongylonematidae, which provides the opportunity to develop novel genetic markers for studies of epidemiology, population genetics and systematics of this nematode of human and animal health significance.

Abstract
Cryptosporidium, a worldwide protozoan parasite, is one of the most common causes of diarrhoea in humans and animals. The aim of the present study was to determine Cryptosporidium species/genotypes in pre-weaned calves in Shaanxi Province using PCR and sequencing based on the small subunit rRNA gene. A total of 258 faecal samples were collected from pre-weaned calves in 19 different farms from six areas in Shaanxi Province, north-western China. Cryptosporidium infection was detected in 14 of 19 farms (73.7 %), with a total prevalence of 20.2 % (52/258). Both dairy and Qinchuan (beef) cattle were found with Cryptosporidium infection. Three Cryptosporidium species, namely Cryptosporidium bovis (n = 26), Cryptosporidium andersoni (n = 14) and Cryptosporidium ryanae (n = 12), were detected in pre-weaned calves in Shaanxi Province, with C. bovis (in 12 farms) identified as the most common species on cattle farms. Two additional and previously unknown C. ryanae genotypes, CRTypes III and IV, were observed in the present study. However, the zoonotic species, Cryptosporidium parvum, was not detected in this study, which suggested a low zoonotic potential in Cryptosporidium-infected pre-weaned calves in this province.

Abstract
Pseudanoplocephala crawfordi is one of the important zoonotic cestodes causing economic significance and public health concern. In the present study, the phylogenetic position of P. crawfordi isolated from pigs was re-inferred using molecular markers of internal transcribed spacer ribosomal DNA (ITS rDNA) and partial NADH dehydrogenase subunit 1 (pnad1) mitochondrial DNA. The lengths of ITS1, ITS2 rDNA and pnad1 were 757 bp, 628 bp and 458 bp, respectively. Sequence differences in the ITS1, ITS2 rDNA and pnad1 between P. crawfordi and Hymenolepis species were smaller than that between cestodes within genus Hymenolepis. Phylogenetic analyses based on three gene fragments showed that P. crawfordi was grouped into cluster of Hymenolepis species. These results suggested that P. crawfordi would be one member of genus Hymenolepis but not in a new genus Pseudanoplocephala.

Abstract
BACKGROUND Nematodirus spp. are among the most common nematodes of ruminants worldwide. N. oiratianus and N. spathiger are distributed worldwide as highly prevalent gastrointestinal nematodes, which cause emerging health problems and economic losses. Accurate identification of Nematodirus species is essential to develop effective control strategies for Nematodirus infection in ruminants. Mitochondrial DNA (mtDNA) could provide powerful genetic markers for identifying these closely related species and resolving phylogenetic relationships at different taxonomic levels. METHODS In the present study, the complete mitochondrial (mt) genomes of N. oiratianus and N. spathiger from small ruminants in China were obtained using Long-range PCR and sequencing. RESULTS The complete mt genomes of N. oiratianus and N. spathiger were 13,765 bp and 13,519 bp in length, respectively. Both mt genomes were circular and consisted of 36 genes, including 12 genes encoding proteins, 2 genes encoding rRNA, and 22 genes encoding tRNA. Phylogenetic analyses based on the concatenated amino acid sequence data of all 12 protein-coding genes by Bayesian inference (BI), Maximum likelihood (ML) and Maximum parsimony (MP) showed that the two Nematodirus species (Molineidae) were closely related to Dictyocaulidae. CONCLUSIONS The availability of the complete mtDNA sequences of N. oiratianus and N. spathiger not only provides new mtDNA sources for a better understanding of nematode mt genomics and phylogeny, but also provides novel and useful genetic markers for studying diagnosis, population genetics and molecular epidemiology of Nematodirus spp. in small ruminants.

Abstract
BACKGROUND Cryptosporidium baileyi is the dominant Cryptosporidium species in birds causing emerging health problems in the poultry industry, and is also a model to study the biology of Cryptosporidium spp.. IL-17 (also called IL-17A) is a hallmark pro-inflammatory cytokine of Th17 cells that plays an important role in several human autoimmune diseases and microbial infection disease of many animals, and it may play a role in Cryptosporidium infection. METHODS The present study examined the mRNA level of IL-17 and Th17 response relative cytokines in the trachea and spleen of C. baileyi-infected chickens at different time points using real-time quantitative PCR (qPCR). RESULTS All examined cytokines in the trachea were up-regulated in the infected chickens compared with the uninfected control during C. baileyi infection. Significant increased IL-17 mRNA level in the trachea was observed as early as 12 h post infection (pi), peaking at 24 h pi and 10 d pi, and declining thereafter. The transcription levels of IL-17 and Th17 response relative cytokines in spleen were also significantly increased at different time points during the infection. CONCLUSIONS IL-17 was indicated to participate in the induction of inflammation during infection of some intracellular protozoan parasites. The results in the present study suggest that IL-17 may play a role in immunity against Cryptosporidium infection, and provide basic information for determining the role of Th17 cell in Cryptosporidium infection.

Abstract
The present study examined sequence variations in three mitochondrial DNA (mtDNA) regions, namely, NADH dehydrogenase subunit 5 (nad5), adenosine triphosphate subunit 6 (atp6) and cytochrome c oxidase subunit 3 (cox3), among Oesophagostomum asperum isolates from different regions in Shaanxi and Hunan provinces, China. The lengths for partial sequences of nad5 (pnad5), atp6 (patp6) and cox3 (pcox3) were 427 bp, 381 bp and 337 bp, respectively. The intra-specific sequence variations among all O. asperum samples were 0-2.11%, 0-1.84% and 0-1.48% for pnad5, patp6 and pcox3, respectively, while the inter-specific sequence differences among Oesophagostomum species in pig and small ruminants were 18-21.3% for pnad5, 18.3-24.5% for patp6 and 10.6-13.7% for pcox3. A phylogenetic analysis based on combined sequences of three mtDNA fragments indicated that all O. asperum isolates were grouped in one solid clade, and the Oesophagostomum spp. from pig were located in another clade. However, these mtDNA fragments could not reveal genetic relationships of geographical isolates of O. asperum in China. These results provided valuable information for studying population genetics of Oesophagostomum spp., and for controlling Oesophagostomum infection in animals as well as humans.

Abstract
The present study examined the variations in three mitochondrial (mt) DNA sequences, namely cytochrome b (cytb), cytochrome c oxidase subunit 3 (cox3) and NADH dehydrogenase subunit 5 (nad5), among Baylisascaris schroederi isolates from the Qinling subspecies of the giant panda in Shaanxi province, northwestern China. No differences in length were detected in the three mt fragments from different isolates. The intra-specific sequence variations within all B. schroederi samples were 0-2.6% for pcytb, 0-1.8% for pcox3 and 0-2.1% for pnad5, while the inter-specific sequence differences among members of the genus Baylisascaris were 8.2-15.2%, 6.2-15.9% and 8.4-16.0% for pcytb, pcox3, pnad5, respectively. A phylogenetic analysis of the combined sequences of pcytb, pcox3 and pnad 5 showed that all B. schroederi samples in the present study were located in two large clusters, with one cluster containing samples from giant pandas in Sichuan province. These findings provide basic information for further study of molecular epidemiology and control of B. schroederi infection in the Qinling subspecies of the giant panda and throughout China.

Abstract
The genetic variations in three mitochondrial DNA (mtDNA) regions, namely portion of cytochrome c oxidase subunit 1 (pcox1), NADH dehydrogenase subunit 1 (pnad1) and cytochrome b (pcytb), were examined for Dicrocoelium dendriticum samples isolated from different origins in Shaanxi Province, northwestern China. The intra-specific sequence differences within D. dendriticum samples were 0-0.52% for pcox1, 0-0.73% for pnad1 and 0-0.58% for pcytb. Phylogenetic analyses based on combined sequences of three mtDNA showed that all D. dendriticum samples were clustered together in same clade of Paragonimus westermani. But the phylogenetic trees could not reveal geographically genetic relationships of D. dendriticum isolates in this province. These findings will provide basic information for further study of molecular epidemiology and control of D. dendriticum infection in this province as well as in China.

Abstract
One hundred and thirty patients with pulmonary mass were studied under ultrasonography guided aspiration biopsy by four types of needle. The cytological positive cases were 57.1% in fine needle (22G), 79.6% in large needle (18G), 90.9% in canaliculated needle (18G) and 80.9% in cutting needle (14G), and the pathological positive cases were 0, 64.4%, 86.3% and 92.8% respectively. These data showed that the positive rate of fine needle puncture was the lowest one. Based on the pathological finding, canaliculated and cutting needle seem to be better than large one and it is the best choice to perform the pulmonary aspiration biopsy.

Abstract
The bioinorganic complexes of europium with N-acetyl-DL-alanine, N-acetyl-DL-valine, and DL-alanyl-DL-alanine have been synthesized and the Mössbauer spectra at room temperature have been measured for these solid state complexes. The Mössbauer parameters indicate that the water molecules in these complexes are not directly linked to the central europium ion and are outside the coordination sphere of europium and biological ligands, and that the chemical bond between the europium ion and the ligands may be predominantly ionic in character, with the possibility of partial covalent contribution.

Abstract
From January 1, 1978 to December 31, 1983, 570 patients with carcinoma of esophagus were treated by 8 MV X-ray and checked by the Philips simulator. In order to assess their value, a series of 3,798 patients reported previously was used for comparison. To further evaluate the effect of 8 MV X-ray and simulator separately, a series of 154 patients was treatment by non-8 MV X-ray during the same period. The results showed that the 1 and 3 year survival rates of 8 MV X-ray series were better than the 3,798 series (P less than 0.01). It means that after the use of simulator and 8 MV X-ray the survival rates were improved. As compared to the radiation other than 8 MV X-ray, there was no difference between 8 MV X-ray and non-8 MV X-ray series, which means that the improvement may have been due to the better localization by the simulator. Having more importance, no radiation myelitis was found after the use of simulator. The sex, age, length, location, X-ray type, NSD and causes of failure were compared in these groups.
