Abstract
The canine transmissible venereal tumor (CTVT) is a clonal cell-mediated cancer with a long evolutionary history and extensive karyotype rearrangements in its genome. However, little is known about its genetic similarity to human tumors. Here, using multi-omics data we identified 11 germline gene fusions (GGFs) in CTVT, which showed higher genetic susceptibility than others. Additionally, we illustrate a mechanism of a complex gene fusion of three gene segments (HSD17B4-DMXL1-TNFAIP8) that we refer to "greedy fusion". Our findings also provided evidence that expressions of GGFs are downregulated during the tumor regressive phase, which is associated with DNA methylation level. This study presents a comprehensive landscape of gene fusions (GFs) in CTVT, which offers a valuable genetic resource for exploring potential genetic mechanisms underlying the development of cancers in both dogs and humans.

Abstract
Objective: To analyze the trajectory of drowning and road traffic injury mortality among children aged 5-14 years in China from 2008 to 2019. Methods: Mortality data of unintentional injuries were from the Mortality Surveillance Data Set of National Disease Surveillance System from 2009 to 2018 and grouped by regions, urban and rural areas, genders, and age groups. The trajectory model was used to analyze the trend of drowning and road traffic injury mortality with years. Results: The mortality of drowning and road traffic injury showed a similar trend. In the trajectory model of drowning mortality, east, middle and west rural boys and western urban boys of all ages belonged to the high mortality group. The moderate mortality group included eastern urban boys and western girls aged 5-9 years and also contained eastern and middle urban boys and western urban girls aged 10-14 years. The other combinations belonged to the low mortality group. In the trajectory model of road traffic injury mortality, western urban boys, all rural boys and western rural girls aged 5-9 years, middle and western rural boys and western urban boys aged 10-14 years belonged to the high mortality group. Eastern urban girls aged 5-9 years and 10-14 years belonged to the low mortality group. The other combinations belonged to the moderate mortality group. Conclusion: There are different groups in the trajectory model of drowning and road traffic injury mortality among children in China. Identifying the trajectory of injury mortality is helpful to carry out more targeted prevention in China.

Abstract
Objective: To describe the prevalence of e-cigarette use among adolescent in Zhejiang province, and to analyze its distribution of different genders and school types to provide evidence for controlling the use of e-cigarette among adolescent. Methods: A total of 7 663 students from 60 middle schools through stratified multi-stage cluster sampling methods from Zhejiang province were surveyed by using questionnaire. Indicators as tried to use e-cigarette rate, current e-cigarette using rate, and other indicators were collected. All data were weighted by age proportions of adolescent in Zhejiang. Results: The prevalence of tried to use and current using e-cigarettes among middle school students were 6.99% and 1.45%, respectively; and there were 4.19% juniors who were susceptibility to future e-cigarette use. The rate of tied to use e-cigarette, current using e-cigarette and susceptibility to future e-cigarette use were higher in boys than in girls. The rate of current using e-cigarette was 2.07% for rural and 0.48% for urban. Technical secondary school students had the highest rate of tried to use e-cigarette and susceptibility to future e-cigarette use (13.53%, 6.91%). Junior school students (2.96%) had the lowest level of susceptibility to future tobacco use. The rate of tried e-cigarette use and current e-cigarette use and susceptibility to future e-cigarette use were higher in the group of "One of students' parents was smoker" (8.63%, 2.19%, 5.23%). The highest rate of current smoking was found in the group of "Weekly allowance more than 50 Yuan" (10.02%, 2.54%, 6.29%). Compared to technical secondary school students, senior school student (OR=0.57) and junior school students (OR=0.45) were less likely to try to use e-cigarette. Students whose weekly allowance were less than 20 Yuan were less likely to try to use e-cigarette (OR=0.49). Students who were boys (OR=5.44) and one of their parents was smoker (OR=1.59) were more likely to try to use e-cigarette. Conclusions: There were middle school students with tried e-cigarette use and current e-cigarette use, especially in technical secondary schools. The prevalence of e-cigarette using among middle school students increased with age. It is important to further spread of e-cigarette knowledge widely and deeply, and reduce the susceptible population of adolescents using e-cigarettes.

Abstract
Tree trunk cankers represent serious fungal diseases that pose significant threats to Chinese hickory trees (Carya cathayensis). To characterize the pathogen diversity associated with this disease, tissues were collected between 2016 and 2018 from the primary Chinese hickory plantation regions. A total of 97 cultures were isolated from trees in six towns (Longgang, Qingliangfeng, Changhua, Tuankou, Taiyang Town, and Lin'an urban area) within the Linan district, where 60% of Chinese hickory tree yields originate. The isolated cultures caused cankers on Chinese hickory tree branches, but infections did not occur on fruits or leaves under tested conditions. Combined morphological observations and phylogenetic analysis of multiple genes (ITS, β-tubulin, and EF) indicated that five Botryosphaeriaceae species were recovered, including 89 isolates of Botryosphaeria dothidea, 4 isolates of Botryosphaeriaceae fabicerciana, 1 isolate of Botryosphaeriaceae qingyuanensis, 1 isolate of Botryosphaeriaceae corticis, and two isolates of Lasiodiplodia theobromae. B. dothidea was the most prevalent, and this is the first report of B. corticis, B. qingyuanensis, and L. theobromae infections in Chinese hickory trees. We investigated the mycelial growth, spore germination, and pathogenicity of these species at different temperatures. L. theobromae grew the fastest and B. cortices grew the slowest on potato dextrose agar. The optimum temperature of spore germination for all species was 30°C. L. theobromae was the most virulent species, followed by B. dothidea and B. qingyuanensis, then B. fabicerciana, and finally B. cortices. These new insights into fungal pathogen diversity provide critical new information to understand and manage tree trunk cankers of Chinese hickory.

Abstract
Objective: Toobserve the damage effects of cytomegalovirus (CMV) infection on hematopoietic cells and to investigate the clinical significance. Methods: (1) ELISA assay wasused to detect IL-17 and IFN-γ levels in the peripheral blood serum of 36 patients on pretherapy and posttherapy. (2) Changes of peripheral blood lymphocyte subsets were detected by FACS. (3) Cytological observation of cervical lymph nodes was executed by needle aspiration cytology. (4) Cellular immunochemistry and immunofluorescence staining were performed to observe the POX release, HLA-DR expression, IL-17A and IFN-γ secretion-like expression status of activated immune cells in the bone marrow hematopoietic microenvironment. Serum samples from healthy individuals were used as controls. Bone marrow smears from patients without iron deficiency anemia were compared as bone marrow immunostaining. Results: (1) Serum levels of IL-17 and IFN-γ were significantly increased in CMV-infected patients [IL-17 (48.23±3.86) ng/L vs (20.16±1.05) ng/L,respectively; IFN-γ (40.16±3.11) vs (8.17±1.92) ng/L,P<0.01]. (2) The proportion of CD16+/CD56+NK cells was significantly increased in patients [(43.54±6.01)% vs (14.01±3.25)%, P<0.01]. The proportion of CD3+CD4+T and CD3+CD8+T cells decreased,(20.91±53.15)% vs (35.10±4.88)%, and (15.41±5.13)% vs (25.11±3.92)%,respectively,P<0.05. (3) Large numbers of abnormal lymphocytes and macrophages (MΦ) that engulf large quantities of CMV inclusion bodies were observed in bone marrow and lymph nodes. CMV infected and destroied the hematopoietic cells of various lines in the bone marrow. The activated MΦ phagocytizedthe CMV inclusion bodies and also phagocytosed CMV-infected blood cells. (4) Activated MΦ in bone marrow hematopoietic microenvironment released POX strongly positive, highly expressed class Ⅱ HLA-DR, and highly expressed inflammatory factors IL-17A and IFN-γ. (5) Twenty-twopatients with elevated WBC were treated with ganciclovir combined with antibiotics for 2 weeks after the disappearance of the foci, WBC counts and CMV-IgM levels of 16 cases were reduced to normal.Six patients with CMV who were not turned negative were tprolonged,and the granulocyte and/or platelet counts fell below normal range. Fourteenpatients withreduced granulocyte or platelet count, CMV-IgM levels were slow descend,and the ganciclovir treated more than 4 weeks. Conclusions: CMV can infect hematopoietic bone marrow nucleated blood cells and destroy hematopoiesis. NK and MΦ cells are important effector cells against CMV infection. Activated macrophages are dual in nature, they can engulf CMV virus and virus-infected blood cells,and also aggravate bone marrow immune damage by releasing inflammatory factors such as POX and IL-17A and IFN-γ.

Abstract
We report the performance enhancement of AlGaN-based deep ultraviolet light-emitting diodes (DUV LEDs) using AlGaN nanoporous template (NPT). The NPT was fabricated by the electrochemical etching method and served as the dislocation filtering layer and strain relieving layer. The n-AlGaN laterally regrown on NPT showed reduced dislocation density and mitigated compressive strain comparing with that on the as-grown template (AGT). A 23% improvement of internal quantum efficiency was achieved for the multiple quantum wells thereon. Moreover, the nanopores in the NPT transformed into elongated air voids during high temperature growth process, which could facilitate the escaping of photons by scattering and thus improve the light extraction efficiency. As a consequence, the DUV LED based on NPT demonstrated an increase of the light outpower by 50% at 20 mA than that on AGT.

Abstract
Objective: To study the effect of adult tobacco use after the implementation of an intervention program, in Zhejiang province from 2010 to 2013. Methods: A total of 2 000 residents aged 15-69 years from 15 counties were selected, using a stratified multi-stage cluster sampling method and a face to face interview on questionnaire, in 2010 and 2013. Intervention program was then implemented. Results: The current smoking prevalence rates were 25.77% and 25.64% respectively in the above-said two years. Comparing data gathered from the 15-69 year olds in Zhejiang province in 2010 and 2013, no statistically significant differences were found in male population, in the 45-64 age group, in the rural population, and in the junior middle school students, regarding the current smoking prevalence rates. 42.11% and 40.56% of the current daily smokers started daily smoking within 30 minutes after waking up in the morning, in 2010 and 2013, and the difference was not significant. Conclusion: Prevalence of smoking in males in Zhejiang remained high,suggesting that publicity and education intervention methods of tobacco control should be effectively improved.

Abstract
Objective: To investigate the understanding of infectious diseases, their prevention, and control, and the factors influencing this literacy among urban and rural residents of Zhejiang Province. Methods: In November- December 2014, a multistage stratified cluster sampling questionnaire was administered at study sites in eight districts of Zhejiang province: Hangzhou city Gongshu district, Hangzhou city Chun'an county, Wenzhou city Cangnan county, Dongyang city, Jiaxing city Jiashan county, Zhoushan city Putuo district, Linhai city, Lishui city Jinyun county. The inclusion criteria were: 15-60 years old, living locally for more than six continuous months, and no mental illness. The exclusion criteria were: foreigner residing locally, resident of Hong Kong, Macau, or Taiwan, or unable to communicate through speech or writing. In this study, 4 091 questionnaires were distributed, and 4 020 valid questionnaires were returned(98.26%). Health literacy regarding infectious diseases was measured at five levels: knowledge, skills, behaviors, access to information, and understanding of the prevention of infectious diseases. A total score was calculated for each questionnaire, and a total score of ≥80 was deemed to indicate an understanding of the prevention of infectious diseases. A χ2 test was used to compare the levels of health literacy in different populations with single-factor analyses, and a multivariate unconditional logistic regression model was used to analyze the factors affecting infectious diseases prevention and treatment literacy levels. Results: Of the 4 020 respondents(aged(43.84 ± 10.28)years), 1 964 were male(48.86%)and 2 056 were female(51.14%). In the total surveyed population, 15.17%(n=610)understood the prevention of infectious diseases, 294 were male(14.97%)and 316 were female(15.37%)(χ2=2.48, P=0.115). When the participants in the different age groups were analyzed, 23.11%, 20.29%, 13.27%, and 11.04% of those aged 18- 29(n=116), 30- 39(n= 166), 40- 49(n=178), and ≥50 years(n=150), respectively, understood infectious disease prevention(χ2= 63.16, P<0.001). When the participants were analyzed according to education, 46.01%, 24.86%, 12.03%, 5.27%, or 2.39% of those educated at university(n=167), at high school/vocational school/college(n=175), at middle school(n=215), at elementary school(n=46), or who were illiterate/slightly literate(n=7), respectively, understood infectious disease prevention(χ2=436.67, P<0.001). Among the urban(n=336)and rural participants(n=274), 18.98% and 12.18% understood infectious disease prevention, respectively(χ2= 35.57, P<0.001), so the urban residents had better health literacy than rural residents(OR=1.28, 95% CI= 1.06- 1.54), and those aged 18- 29 or 30- 39 years had even better health literacy than the rural residents(OR=1.39, 95%CI=1.01-1.91). When the health literacy levels of migrant workers were compared with those of agency/institutional personnel, business people, unemployed, and retirees, the OR(95% CI)values were 2.52(1.82-3.49), 1.69(1.24-2.30), 2.99(1.65-5.39), and 2.43(1.59-3.72), respectively. When the illiterate/slightly literate were compared with those educated at university, high school/vocational school/secondary school, and junior high school, the OR(95%CI)values were 35.11(15.73-78.36), 13.31(6.11-28.99), and 5.37(2.48-11.62), respectively. Conclusion: Limited levels of health literacy are common among the residents of Zhejiang Province. Lower education level, older age, and rural residence were predictors of low health literacy in this study.

Abstract
Objective: The aim of this study is to investigate the underlying mechanism of cinnamaldehyde attenuating pressure overload-induced cardiac fibrosis. Methods: The mice were randomly divided into control group, model group and treatment group by random number table and each group had 8 mice.Cardiac hypertrophy was induced by aortic banding. Heart vascular density was detected by immunohistochemical staining of CD31.The expression level of stromal cells marker α-smooth muscle actin (α-SMA) was detected by immunofluorescence staining in different groups.The expression levels of endothelial cell associated markers and stromal cell associated markers were detected by using Western blotting.The possible molecular pathway was also screened by using Western blotting. Human umbilical vein endothelial cell (HUVECs) were stimulated with TGFβ1 and cultured with 10 nmol/L cinnamomum for 24 hour to further confirm the mechanism. Results: Eight weeks after operation, the vascular density was significantly decreased in model group mice heart.The expressions of stromal cells markers were increased (α-SMA: 2.57±0.38; Vimentin: 0.58±0.02) and endothelial cell markers were reduced (CD31: 0.58±0.29; CD34: 0.62±0.21). While cinnamicaldehyde treatment significantly increased the mouse heart vascular density, increased endothelial cell markers expression (CD31: 1.51±0.11; CD34: 2.37±0.44; P<0.05), and reduced stromal cells marker expression (α-SMA: 1.22±0.14; Vimentin: 0.35±0.03; P<0.05). Further studies showed that the anti-fibrosis effect of cinnamicaldehyde was mainly through the TGFβ /smad signaling pathway.10 nmol/L cinnamomum attenuated TGFβ1 induced endothelial mesenchymal transition in HUVECs. Conclusion: Cinnamaldehyde may be able to retard the progression of cardiac fibrosis, via blocking endothelial to mesenchymal transition, which, in verse, is through regulating TGFβ /smad signaling pathway.

Abstract
Mitogen-activated protein kinase kinase kinase 5 (MAP3K5) is essential for apoptosis, proliferation, differentiation, and immune responses, and is a candidate marker for residual feed intake (RFI) in pig. We cloned the full-length cDNA sequence of porcine MAP3K5 by rapid-amplification of cDNA ends. The 5451-bp gene contains a 5'-untranslated region (UTR) (718 bp), a coding region (3738 bp), and a 3'-UTR (995 bp), and encodes a peptide of 1245 amino acids, which shares 97, 99, 97, 93, 91, and 84% sequence identity with cattle, sheep, human, mouse, chicken, and zebrafish MAP3K5, respectively. The deduced MAP3K5 protein sequence contains two conserved domains: a DUF4071 domain and a protein kinase domain. Phylogenetic analysis showed that porcine MAP3K5 forms a separate branch to vicugna and camel MAP3K5. Tissue expression analysis using real-time quantitative polymerase chain reaction (qRT-PCR) revealed that MAP3K5 was expressed in the heart, liver, spleen, lung, kidney, muscle, fat, pancrea, ileum, and stomach tissues. Copy number variation was detected for porcine MAP3K5 and validated by qRT-PCR. Furthermore, a significant increase in average copy number was detected in the low RFI group when compared to the high RFI group in a Duroc pig population. These results provide useful information regarding the influence of MAP3K5 on RFI in pigs.

Abstract
A "basket in a basket" method based on a multistage accurate mass spectrometric (MAMS) technique was developed and demonstrated by obtaining a unique elemental composition of a compound (with a molecular weight of 517) from combinatorial synthesis. The accurate masses for the parent and the fragment ions were obtained with up to five stages of MAMS using Fourier transform ion cyclotron resonance mass spectrometry (FTICR-MS). This approach requires only input of elements used in the synthetic processes and some constraints about unusual light elements, such as fluorine, while the compositions of the parent ions and their fragments are obtained for structure elucidation. Conversely, accuracy of better than 0.02 ppm (assuming elements C, H, N, O, S, and F are involved) would be required in order to define a unique composition for the same mass using a direct accurate mass measurement because the number of possible elemental compositions increases sharply as the mass increases. Similarly, due to the uncertainty in determining elemental compositions of fragments and complexity of possible internal fragmentation, tandem mass spectrometry may not provide enough information for structure elucidation of unknown compounds, especially of the organic molecules in the mass range of 300-1000 Da, typically encountered in combinatorial lead generation. The application of MAMS to combinatorial drug discovery is particularly advantageous since the built-in chemical information from the synthesis can be used as constraints. The implementation of a nanoelectrospray ionization technique makes this approach practical for characterization of small quantities of compounds typically available from lead generation processes.

Abstract
Mechanical stress-induced matrix deformation plays a fundamental role in regulating cellular activities; however, little is known about its underlying mechanisms. To understand the effects of matrix deformation on chondrocytes, we characterized primary chondrocytes cultured on three-dimensional collagen scaffoldings, which can be loaded mechanically with a computer-controlled "Bio-Stretch" device. Cyclic matrix deformation greatly stimulated proliferation of immature chondrocytes, but not that of hypertrophic chondrocytes. This indicates that mechanical stimulation of chondrocyte proliferation is developmental stage specific. Synthesis of cartilage matrix protein (CMP/matrilin-1), a mature chondrocyte marker, and type X collagen, a hypertrophic chondrocyte marker, was up-regulated by stretch-induced matrix deformation. Therefore, genes of CMP and type X collagen are responsive to mechanical stress. Mechanical stimulation of the mRNA levels of CMP and type X collagen occurred exactly at the same time points when these markers were synthesized by nonloading cells. This indicates that cyclic matrix deformation does not alter the speed of differentiation, but affects the extent of differentiation. The addition of the stretch-activated channel blocker gadolinium during loading abolished mechanical stimulation of chondrocyte proliferation, but did not affect the up-regulation of CMP mRNA by mechanical stretch. In contrast, the calcium channel blocker nifedipine inhibited both the stretch-induced proliferation and the increase of CMP mRNA. This suggests that stretch-induced matrix deformation regulates chondrocyte proliferation and differentiation via two signal transduction pathways, with stretch-activated channels involved in transducing the proliferative signals and calcium channels involved in transducing the signals for both proliferation and differentiation.

Abstract
Liquid nitrogen (LN) cryosurgery is more often used for the treatment of bone tumors of the extremities. Since 1985 after animal experimentation we began to use it for the surgical treatment of spinal tumors. The temperature of the tissues surrounding the spinal cord was controlled above -20 degrees C by means of thermocouples and somatosensory evoked potentials (SEP) was used to monitor the spinal cord function. Liquid nitrogen was used as an adjuvant treatment in the surgical treatment of spinal tumors, it could reduce operative hemorrhage and kill tumor cells. The function of spinal cord had not been damaged in all 11 patients after cryotherapy. There was infection in one case, it was cured by using antibiotics and by drainage. This study showed that LN freezing can reduce the amount of operative hemorrhage during resection of spinal tumors. Benign tumors can be thus removed easily and thoroughly.

Abstract
This study consisted of 149 newly diagnosed cases of tuberculosis of the spine; these were alloeated into the following two regimens: 4SHER/5HER and 4SHER/5H3E3R3. 145 cases have completed their chemotherapy. In patients (2.7%) the allocated regimens was modified because of adverse reactions. All of the patients except 9 cases, operative debridment of the spinal focus was performed within 1-3 months of the start of chemotherapy. Some of the results from this study were encouraging: (1) the therapeutic response was favourable in both regimens, and adverse reactions, mainly hepatic toxicity, were rather low, (2) after a four-month initial intensive phase, both intermittent administration for 5 months or daily treatment for 5 month in the continuation phase were of the same high efficacy at the end of treatments as well as during 4-44 months follow-up.
