Abstract
To establish the prognostic factors for primary intraosseous squamous cell carcinoma we designed a retrospective study of patients treated in the head and neck department of a tertiary referral centre in China from 2010-2015. We collected clinical, radiological, and histopathological data from 36 patients treated during the given time period, among which 34 were followed up. There were 22 male and 12 female patients, 13 of whom gave a history of smoking tobacco and four who drank alcohol. All 34 patients were treated by segmental mandibulectomy and neck dissection. Nine had cervical lymph node metastases on histopathological examination, and none had invaded surgical margins. Twenty-eight were treated with radiotherapy postoperatively. During follow up nine died of locoregional recurrence or metastases. Specific factors such as cervical lymph node metastases were related to a greater likelihood of locoregional recurrence. Patients who drank alcohol were also more likely to develop metastases postoperatively. Tumours more than 4cm in size were significantly associated with reductions in locoregional control and survival.

Abstract
BACKGROUND AND PURPOSE The multiple stent placement technique has largely improved the long-term outcomes of intracranial fusiform aneurysms, but the hemodynamic mechanisms remain unclear. In this study, we analyzed the hemodynamic changes caused by different stent-placement strategies in patient-specific models using the computational fluid dynamics technique, aiming to provide evidence for clinical decision-making. MATERIALS AND METHODS Ten vertebral artery fusiform aneurysms were included, and their patient-specific computational fluid dynamics models were reconstructed. A fast virtual stent placement technique was used to simulate sequential multiple stent placements (from a single stent to triple stents) in the vertebral artery fusiform aneurysm models. Hemodynamic parameters, including wall shear stress, pressure, oscillatory shear index, relative residence time, and flow pattern, were calculated and compared among groups with different numbers of stents. RESULTS Virtual stents were deployed in all 10 cases successfully, consistent with the real stent configuration. Wall shear stress decreased progressively by 7.2%, 20.6%, and 25.8% as the number of stents increased. Meanwhile, relative residence time and pressure increased on average by 11.3%, 15.4%, and 45.0% and by 15.7%, 21.5%, and 28.2%. The oscillatory shear index showed no stable variation trend. Flow patterns improved by weakening the intensity of the vortices and displacing the vortex center from the aneurysmal wall. CONCLUSIONS Stent placement modifies hemodynamic patterns in vertebral artery fusiform aneurysms, which might favor thrombosis formation in the aneurysmal sac. This effect is amplified with the number of stents deployed. However, a potential risk of rupture or recanalization exists and should be considered when planning to use the multiple stent placement technique in vertebral artery fusiform aneurysms.

Abstract
Until now, there are no completely effective parasite-specific pharmaceuticals or immunotherapies for treatment against the zoonotic cryptosporidiosis. Sushi domain (CpSushi) is an important functional domain in Cryptosporidium parvum putative rhoptry protein-1 (CpPRP1), which is the only reported C. parvum rhoptry protein and may play key role in the course of invasion. Here, a 708-bp fragment encoding the CpSushi domain was amplified and expressed in E. coli. Immunofluorescence detection showed that CpSushi was located on the surface of C. parvum oocysts and the apical pole to the sporozoites that belonged to the position of rhoptry. Three-week-old female ICR mice were used for detecting the immunoreactions and immunoprotection of recombinant CpSushi (rCpSushi) to artificial C. tyzzeri infection. The results indicated that a significant increase of anti-CpSushi antibody response was induced by the recombinant protein. Compared to blank, Tris-EDTA (TE) buffer and adjuvant controls mice, rCpSushi-immunized mice produced specific spleen cell proliferation as well as enhanced IL4, IL5, IL12p70 and TNF-α production in vitro. The reduction rate of parasites shedding in stool in mice immunized with rCpSushi was 68.91% after challenging with C. tyzzeri. These results suggest that CpSushi could be a new promising cryptosporidiosis vaccine candidate antigen composition.

Abstract
Objective: To investigate breakfast status and influencing factors among children aged 6-17 in China in 2010-2012. Methods: Data were collected from China National Nutrition and Health Surveillance in 2010-2012. By using multi-stage stratified sampling and population proportional stratified random sampling method, the research objects were 29 393 children, who aged 6 to 17 y from 150 sites in 31 provinces in mainland China. The information of breakfast frequency and the numbers of breakfast dinning out (in restaurant and at schools) in the past week with seven days were collected by questionnaire; and compared by different ages, genders and areas. Results: During the past week, 91.1% (26 776/29 393) of the children aged 6 to 17 y had their breakfast daily, and 94.6% (13 457/14 221) of children aged 6 to 11 y was higher than 87.8% (13 319/15 172) of children aged 12 to 17 y, the highest proportion of the children never eat breakfast (0 time in the past week) found in poor rural areas was 3.6% (189/5 261), the ratio of big cities, small-medium cities and normal rural areas was 1.1% (77/7 104), 0.6% (51/8 361), and 0.6% (54/8 667), respectively (P<0.001). The rate of boys and girls ate their breakfast daily in the past week were 91.3% (13 481/14 761), and 90.9% (13 295/14 632), respectively (P>0.05). Totally 42.2% (12 398/29 393) of children ate breakfast outside-home (the restaurant and the school) in the past week, the percentage of children aged 12 to 17 y and poor rural areas was higher, 50.9% (7 722/15 172), and 52.4% (2 756/5 261), respectively (P<0.001). 42.1% (6 208/14 761) boys and 42.3% (6 190/14 632) girls ate their breakfast outside-home (P>0.05). The place of most school-age children eat outside-home was school, the ratio was 32.2% (9 477/29 393). Conclusion: It was common for school-aged children in China to skip breakfast during their daily lives, especially in poor rural areas and older children, lots of school-aged children ate breakfast outside-home, and most of them ate breakfast in school.

Abstract
Since early 2017, several outbreaks of Seneca Valley virus (SVV) infection have re-emerged in China. We report the identification of novel SVV KS15-01-like strains showing a notable distinction with previous Chinese SVV strains. The determined SVV strains are currently causing new outbreaks in two provinces in China where no SVV infection has been reported previously, implying the increased epidemic regions and potential threat to local pig breeds of SVV in China.

Abstract
A cross was made of Elymus repens onto the wheat cultivar Crocus and BC1 progeny advanced to BC1F7 by single seed descent. Sixteen lines were selected based on agronomic performance and evaluated in an FHB epiphytotic nursery. Eight lines with FHB resistance were selected. Based on GISH analysis, line P1142-3-1-5 had 42 chromosomes with one pair of chromosomes showing telomeric translocations on both arms. This chromosome was identified as 3D by using SSR markers. An evaluation of lines with single translocations revealed that FHB resistance was contributed by the translocation on the long arm of chromosome 3D. That line has minimal linkage drag and should be amenable to applications in breeding for disease resistance.

Abstract
To improve understanding of Salmonella Typhimurium LT2 inactivation in ground poultry carcasses, a series of experiments were carried out at multiple temperatures. Subsequently, a non-linear model was developed to predict Salmonella inactivation at composting and low rendering temperatures. The Salmonella inactivation study was conducted using bench-top experiments at 38, 48, 55, 62.5, 70, and 78°C in mixed and non-mixed reactors using ground poultry carcasses as a feedstock. Subsequently, these observations were used for developing a non-linear model. The model predictions were compared with the observations of a different set of experiments. The comparisons among predictions and observations showed that the model predictions are reasonable and can be useful to determine the time required for Salmonella inactivation in poultry carcasses at multiple temperatures. Results showed that at composting conditions, when temperature varies between 48 and 62.5°C, Salmonella survival can prolong between 10,000 and 25,000 min (7 to 17 d). If ambient temperature is maintained at low temperature rendering range (70 to 78°C), then Salmonella survival can last for 90 to 120 minutes. We anticipate that this study will help in improving the existing understanding of Salmonella survival in poultry carcasses.

Abstract
Objective: To observe the effects of early applying of microporous polysaccharide on foreign body reaction induced by subcutaneously imbedding expanded polytetrafluoroethylene (e-PTFE) in mice. Methods: Ten wide type adult C57BL/6J mice were collected and made a full-thickness skin incision on both sides of their back. The two incisions on the back of each mouse were divided into two groups according the random number table, with 10 incisions in each group. A tube-shaped e-PTFE was imbedded into each incision in microporous polysaccharide group, and then 0.03 g microporous polysaccharide was evenly sprayed in the cavity. Whereas, a tube-shaped e-PTFE was imbedded into each incision in control group without other treatment. The incisions in two groups were performed with conventional full-thickness suture. On post operation day (POD) 14, the e-PTFE surrounded with fibrous capsule in each incision of two groups was taken out, and then fibrous capsule tissue was harvested. The thickness of fibrous capsule was observed and measured with HE staining. Collagen fiber distribution in fibrous capsule tissue was observed with Masson staining to calculate the collagen fiber index. Neovascularization and macrophage infiltration in fibrous capsule tissue were observed respectively with immunohistochemical staining, and the numbers of new vessels and macrophages were counted. Data were processed with t test. Results: On POD 14, the thickness of fibrous capsule surrounding e-PTFE imbedded into the incision of microporous polysaccharide group was (127±19) μm, which was significantly thinner than that of control group [(250±35) μm, t=4.13, P<0.05]. On POD 14, the collagen fiber index of fibrous capsule tissue surrounding e-PTFE imbedded into the incision of microporous polysaccharide group was 0.500±0.003, which was significantly higher than that of control group (0.488±0.004, t=5.00, P<0.05). On POD 14, the number of new vessels in fibrous capsule tissue surrounding e-PTFE imbedded into the incision of microporous polysaccharide group was 19±3 per 400 fold visual field, which was significantly more than that of control group (11±3 per 400 fold visual field, t=2.05, P<0.05). On POD 14, the number of macrophages in fibrous capsule tissue surrounding e-PTFE imbedded into the incision of microporous polysaccharide group was 64±5 per 400 fold visual field, which was close to that of control group (66±7 per 400 fold visual field, t=0.78, P>0.05). Conclusions: Topically applying microporous polysaccharide can reduce the formation of fibrous capsule after subcutaneous imbedding of e-PTFE in mice, and it can improve the collagen deposition and angiogenesis but not impact on macrophage infiltration.

Abstract
OBJECTIVE To study the intratumor heterogeneity of esophageal squamous cell carcinoma (ESCC). METHODS We used whole-exome sequencing and array-based comparative genomic hybridization to profile mutations and changes in copy number from 11 regions within 2 cases of ESCC and from the metastatic lymph nodes. RESULTS The numbers of somatic single nuclear polymorphisms (SNPs) in 4 regions within the tumors in case 1 and case 2 were 93±17 and 124±28, respectively. The majority of SNPs were non synonymous mutations, synonymous mutations, nonsense mutations and splicing junction mutations. The average indels in the 4 tumor regions of case 1 and case 2 were 40±6 and 51±3, respectively. These small indels mainly occurred in exonic (frame-shift and non-frame-shift), untranslational regions of genes and splicing junction regions. All regions from a tumor exhibitedo bvious heterogeneity, and mutational similarity of all four regions within a tumor was less than 25%. Furthermore, gene copy number alteration (gain or loss) varied among multiple regions of a tumor, and the similarity of gene copy number was less than 20%. Phylogenetic analysis of the somatic mutation frequency suggests that multiple, genomic heterogeneous clones co-exist within a primary ESCC, and metastatic subclones may evolve from the primary non-metastatic parental clone. These results indicated that a single-region sampling can not reflect the architecture of the genomic landscape of mutations in ESCC tumors. CONCLUSIONS Sequence analysis of whole genome exon in multiple regions can provide strong evidence for genomic heterogeneity in esophageal squamous cell carcinoma.

Abstract
Recent genome-wide association studies (GWAS) demonstrated that genetic variation in intron 2 of fibroblast growth factor receptor 2 (FGFR2) was a novel risk for breast cancer. We investigated whether two SNPs rs1219648 and rs2981582 in intron 2 of FGFR2 were associated with the risk of breast cancer in Chinese women. A total of 340 female breast cancer patients and 400 normal age-matched controls were recruited. Two SNPs were genotyped using matrix-assisted laser desorption/ionization mass spectrometry. The two SNPs rs1219648 and rs2981582 showed no association with the risk of breast cancer. A subgroup analysis by menopausal status demonstrated that the distribution of rs2981582 T alleles, including CT and TT genotypes, was significantly higher in premenopausal patients compared with postmenopausal patients. The TT genotype in rs2981582 was more strongly associated with ER-positive than with ER-negative tumors by ER status analysis. Analysis by haplotypes showed that no haplotypes associated with breast cancer. The results showed no association between two SNPs, rs1219648 and rs2981582 and breast cancer risk, although in a stratified analysis rs2981582 strongly associated with premenopausal and ER-positive breast cancer patients in Chinese women.
