Abstract
In order to compare the pathogenicity of different Tembusu virus (TMUV) strains from geese, ducks and chickens, 56 5-day-old Cherry Valley ducklings which were divided into 7 groups and infected intramuscularly with 7´105 PFU/ml per duck of six challenge virus stocks. The clinical signs, weight gain, mortality, macroscopic and microscopic lesions, virus loads in sera of 1, 3, 5, 7, 11 and 14 dpi and serum antibody titers were examined. The results showed that these viruses could make the young ducks sick, but the clinical signs differed with the different species-original strains. All the experimental groups lose markedly in weight gain compared to the control, but there were no obvious distinctions in weight gains, as well as macroscopic and microscopic lesions of dead ducks between the infected groups. However, the groups of waterfowl-derived strains (from geese and ducks) showed more serious clinical signs and higher relative expressions of virus loads in sera than those from chicken-derived. The mortality of waterfowl groups was 37.5%, and the greatest mortality of chicken groups was 12.5%. The serum antibodies of the geese-species group JS804 appeared earlier and were higher in the titers than others. Taken toghter, the pathogenicity of waterfowl-derived TMUV was more serious than chicken-derived TMUV and JS804 could be chosen as one TMUV vaccine strain to protect from the infection.

Abstract
Objective: To study the relations between famine exposure and the risk of chronic diseases as diabetes mellitus, obesity, hypertension, coronary heart disease and stroke in the population of Harbin. Methods: Our data was collected from the baseline survey-the China Kadoorie Biobank project (CKB) in Harbin. Retrospective cohort study design was used. Related risks on chronic diseases including diabetes mellitus, obesity, hypertension, coronary heart disease and stroke, were compared among the famine exposed or non-exposed people, respectively by logistic analysis method. Results: After adjusted for factors as age, sex, physical activity, smoking, alcohol intake, diet, family history of diseases, it appeared that the factor 'famine exposure' had increased the risks of diseases as obesity (OR=1.204, 95%CI: 1.104-1.313, P<0.01), hypertension (OR=1.315, 95%CI: 1.210-1.429, P<0.01) and coronary heart disease (OR=1.495, 95%CI: 1.369-1.632, P<0.01). The lower the age of population being exposed to famine, the greater the risk of the development of all kinds of chronic diseases. Conclusions: Famine exposure appeared a risk factor for obesity, hypertension, and coronary heart disease. It is of great significance to ensure the life-long nutrition of the people, especially in the early and adolescent stages, to prevent obesity, hypertension, and coronary heart disease in their later lives.

Abstract
An advanced in vitro cervical tumor model was established by 3D printing to study the epithelial-to-mesenchymal transition (EMT), which is a very important stage of dissemination of carcinoma leading to metastatic tumors. A HeLa/hydrogel grid construct composed of gelatin, alginate, Matrigel and HeLa cells was fabricated by forced extrusion in a layer-by-layer fashion. HeLa cells rapidly proliferated, formed spheroids and presented tumorigenic characteristic in the 3D-printed structure. With the supplement of TGF-β, aggregated HeLa cells started to disintegrate, and some of them changed into fibroblast-like spindle morphology, which indicated that EMT was induced. The down-regulation of epithelial marker E-cadherin, and up-regulation of mesenchymal markers such as snail, vimentin and N-cadherin were all observed in the 3D-printed model, and performed differently in 3D and 2D models. The TGF-β induced EMT was inhibited by the treatment of disulfiram and EMT pathway inhibitor C19 in a dose dependent manner, showing great potential for future studies of a therapeutic program towards cervical tumor metastasis.

Abstract
All birds reproduce by internal fertilization, but only 3% of birds have external genitalia. Hormone secretions and body size influence genital growth, but the actual regulatory mechanism is rarely reported. Thus, using 35 geese as experimental material, the regulatory mechanism of goose external genitalia growth was explored by measuring body size parameters, serum hormone concentrations, and related gene expression. In this study, genital growth was different among tested geese, but histological and morphological results showed that all geese external genitalia contained complete tissues. Measurements of hormone levels showed that at puberty, as the genital length increased, irregular decreases were observed in the levels of follicle-stimulating hormone (FSH) and luteinizing hormone (LH), whereas an irregular increase was observed in the levels of testosterone (T); furthermore, the levels of testosterone (T) gradually increased to a peak at 34 weeks. Based on RT-PCR results, as the genital length increased, only the expression of 17α-hydroxylase/17, 20-lyase (CYP17) mRNA slightly decreased at first, and then significantly increased to a peak, whereas the expression patterns of other genes were irregular. Furthermore, the CYP17 immunohistochemistry results also showed a pattern that was highly consistent with the patterns of mRNA expression and T secretion. In addition, based on body measurements, as body weight increased, the genital length increased. Thus, these results suggested that the CYP17 gene plays a key role in goose genital growth.

Abstract
Objective: To investigate the effect of recombinant human keratinocyte growth factor 2 (rhKGF-2) on lung tissue of rabbits with severe smoke inhalation injury. Methods: A total of 120 New Zealand rabbits were divided into 5 groups by random number table after being inflicted with severe smoke inhalation injury, with 24 rats in each group. Rabbits in the simple injury group inhaled air, while rabbits in the injury+phosphate buffer solution (PBS) group inhaled 5 mL PBS once daily for 7 d. Rabbits in injury+1 mg/kg rhKGF-2 group, injury+2 mg/kg rhKGF-2 group, and injury+5 mg/kg rhKGF-2 group received aerosol inhalation of 1 mg/kg, 2 mg/kg, and 5 mg/kg rhKGF-2 (all dissolved in 5 mL PBS) once daily for 7 d, respectively. On treatment day 1, 3, 5, and 7, blood samples were taken from the ear central artery of 6 rabbits in each group. After the blood was taken, the rabbits were sacrificed, and the tracheal carina tissue and lung were collected. Blood pH value, arterial oxygen partial pressure (PaO(2)), arterial blood carbon dioxide pressure (PaCO(2)), and bicarbonate ion were detected by handheld blood analyzer. The expressions of pulmonary surfactant-associated protein A (SP-A) and vascular endothelial growth factor (VEGF) in lung tissue were detected by Western blotting. Pathomorphology of lung tissue and trachea was observed by hematoxylin-eosin staining. Data were processed with analysis of variance of two-way factorial design and Tukey test. Results: (1) Compared with those in simple injury group, the blood pH values of rabbits in the latter groups on treatment day 1-7 had no obvious change (P>0.05). The PaO(2) of rabbits in injury+2 mg/kg rhKGF-2 group on treatment day 5 and 7 were (75.0±2.4) and (71.0±4.5) mmHg (1 mmHg=0.133 kPa), respectively, which were significantly higher than (62.0±6.8) and (63.0±3.0) mmHg in simple injury group (q=4.265, 8.202, P<0.05 or P<0.01). The PaO(2) of rabbits in injury+5 mg/kg rhKGF-2 group on treatment day 7 was (82.0±4.9) mmHg, which was significantly higher than that in simple injury group (q=6.234, P<0.01). Compared with that in simple injury group, the PaCO(2) of rabbits in injury+2 mg/kg rhKGF-2 group on treatment day 3 was significantly decreased (q=4.876, P<0.01) and significantly increased on treatment day 5 (q=5.562, P<0.01); the PaCO(2) of rabbits in injury+5 mg/kg rhKGF-2 group was significantly increased on treatment day 5 and 7 (q=5.013, 4.601, P<0.05 or P<0.01). Compared with that in simple injury group, the serum bicarbonate ion of rabbits in injury+1 mg/kg rhKGF-2 group on treatment day 7 was significantly increased (q=5.142, P<0.01); the serum bicarbonate ion of rabbits in injury+2 mg/kg rhKGF-2 group on treatment day 5 and 7 were significantly increased (q=4.830, 6.934, P<0.01); the serum bicarbonate ion of rabbits in injury+5 mg/kg rhKGF-2 group on treatment day 5 were significantly increased (q=3.973, P<0.05). (2) The expressions of SP-A in lung tissue of rabbits in simple injury group and injury+PBS group in each treatment time point were close (P>0.05). The expressions of SP-A in lung tissue of rabbits in injury+2 mg/kg rhKGF-2 group and injury+5 mg/kg rhKGF-2 group on treatment day 3 were 0.091±0.007 and 0.101±0.009, respectively, significantly higher than 0.069±0.009 in simple injury group (q=10.800, 13.580, P<0.01). The expressions of SP-A in lung tissue of rabbits in injury+1 mg/kg rhKGF-2 group, injury+2 mg/kg rhKGF-2 group, and injury+5 mg/kg rhKGF-2 group on treatment day 5 and 7 were 0.127±0.008, 0.132±0.006, 0.194±0.006, 0.152±0.017, 0.166±0.004, 0.240±0.008, significantly higher than 0.092±0.003 and 0.108±0.005 in simple injury group (q=6.789, 12.340, 17.900, 9.875, 31.480, 40.740, P<0.01). (3) On treatment day 1 and 5, there was no significant difference in the expression of VEGF in lung tissue of rabbits among the 5 groups (P>0.05). Compared with those in simple injury group, the expressions of VEGF in lung tissue of rabbits in injury+2 mg/kg rhKGF-2 group on treatment day 3 and 7 were significantly increased (q=4.243, 8.000, P<0.05 or P<0.01), and the expression of VEGF in lung tissue of rabbits in injury+5 mg/kg rhKGF-2 group on treatment day 7 was significantly increased (q=20.720, P<0.01). (4) On treatment day 1, the injury of rabbits in each group was similar, with a large number of neutrophils infiltrated and abscess formed in the alveolar and interstitial tissue, thickened alveolar septum, some collapsed alveolar and atelectasis; large area of tracheal mucosa was degenerated and necrotic, with a large amount of inflammatory exudates blocking in the cavity. On treatment day 3, the inflammation of lung tissue and trachea in each group were improved, but the inflammation in simple injury group and injury+PBS group was also serious. On treatment day 5, the inflammation in lung tissue and trachea of rabbits in injury+2 mg/kg rhKGF-2 group and injury+5 mg/kg rhKGF-2 group were improved much obviously than those in the other groups. On treatment day 7, the inflammation in lung tissue of rabbits in injury+5 mg/kg rhKGF-2 group alleviated obviously than those in the other groups, most alveoli had no obvious exudative fluid, the alveolar cavity was intact and clear, the local alveolar dilated like a cyst, and the alveolar septum thinning; the improvement of inflammation of trachea was more obvious than the other groups, the tracheal mucosa tended to be more complete, and few neutrophils were infiltrated in the endotracheal cavity. Conclusions: Atomization inhalation of rhKGF-2 can improve the PaO(2) level of rabbits with severe smoke inhalation injury, reduce airway inflammation, increase the expression of SP-A and VEGF in lung tissue, thus promoting the repair of lung tissue.

Abstract
Early airway management and respiratory support are essential for severe inhalation injury. Intratracheal delivery of drugs is better than other methods of administration, because of its higher local drug concentration, faster and more precise effect, and less systemic adverse reactions. It attracts more and more attention at present. In recent years, a growing number of drugs can be used in intratracheal delivery, in addition to common bronchodilators, mucolytics, and glucocorticoids, there are anti-inflammatory agents, antioxidants, and anticoagulants, etc. It is of great significance to improve the prognosis of patients with inhalation injuries with intratracheal delivery of drugs in goal-targeted therapy.

Abstract
Objective: To investigate the combination effect of anti-tumor agent rapamycin and anti-autophagy agent chloroquine on osteosarcoma. Methods: The inhibition effect of rapamycin or chloroquine and combination of both on human osteosarcoma cell line 143B measured with CCK-8 box.The combination index at different concentration was calculated, and the synergism effect range was analysed.The effect of combined therapy on cell cycle and apoptosis via flow cytometric was analyzted.Setting up murine subcutaneous xenograft model, the combination effect of antitumor in vivo observed. Results: Either of them, rapamycin or chloroquine had an antitumor effect in vitro (RAPA: IC50=1.5 nmol/L; CQ: IC50=400 μmol/L). When the inhibition rate 40%<fa<70%, the combination had synergism effect (CI<1) at different concentration.Moreover, when CQ at 200 μmol/L, the synergism effect was the most obvious, CI(min)=0.255.The flow cytometric analysis display rapamycin at 1.5 nmol/L had slightly promote apoptosis effect (16.1%±4.4%), and had distinct cell cycle arrest, mainly blocked at G0/G1 phase (73.5%±10.6%; control group: 46.7%±7.7%; P<0.001). While combined with chloroquine, the apoptosis cell obviously increased (21.3%±6.8%; P<0.05). The xenograft model also confirmed that rapamycin combined with chloroquine had a better antitumor effect than single usage (relative tumor proliferation rate; T/C%.CQ: 98.4%±11.6%; RAPA: 65.5%±7.5%; CQ+ RAPA: 42.0%±3.4%). Conclusion: Rapamycin combine with chloroquine can increase the antitumor efficacy, and the combination therapy maybe a potential therapeutic regimen.

Abstract
Sirt1 promotes odontoblastic gene expression in human dental pulp cells, whereas the inhibition of Sirt1 downregulates the expression of those genes. To investigate whether the overexpression of Sirt1 in mesenchymal stem cells (MSCs) driven by Prx1 promoter could rescue the dentin formation defects in Bmi1-deficient (Bmi1-/-) mice, we established the MSCs overexpressing Sirt1 in Bmi1 knockout mice (Sirt1TGBmi1-/-). First, we used Prx1-Cre/ROSAnTnG mice to demonstrate that Prx1 linage cells exist mainly in the pulp horns at 4 wk of age. Second, we found that 4-wk-old Sirt1TG mice had increased tooth volume as compared with wild-type (WT) littermates. The expression level of Sirt1 was significantly higher in dental papilla mesenchymal cells of Sirt1TG mice than WT mice. Furthermore, we demonstrated that the tooth mineralization, dental volume, dentin sialoprotein-immunopositive areas, odontoblastic gene expression, and percentage of proliferating BrdU-positive cells were significantly elevated in the Sirt1TG mice and dramatically reduced in the Bmi1-/- mice versus the WT littermates at 4 wk of age. However, the areas of predentin and the percentage of TUNEL-positive apoptotic cells were significantly reduced in the Sirt1TG mice but dramatically increased in the Bmi1-/- mice as compared with the WT littermates. All these parameters were rescued in the Sirt1TGBmi1-/- mice versus the Bmi1-/- mice. Finally, by using dental papilla mesenchymal cells, we found that the overexpression of Sirt1 rescued the reduced cell proliferation and differentiation and increased the cell apoptosis caused by Bmi1 deficiency, which was associated with increased p53 deacetylation. Therefore, this study indicates that Sirt1 is a potential therapeutic target for promoting dentin formation in an anabolic approach to the treatment of dental developmental defects.

Abstract
Objective:To explore the effect of individualized multi-compound sound therapy on chronic subjective tinnitus and the relationship between tinnitus frequency," notch " hearing loss and the treatment effect of sound therapy.Method: Seventy-eight cases of chronic subjective tinnitus with the pure tone test threshold (PTA)in normal range (≤25 dB HL)were enrolled in this study. Their hearing threshold were re-evaluated using the precise pure-tone audiogram (P-PTA).Tinnitus was evaluated on pitch and loudness matching, and the effectiveness of tinnitus was measured using Tinnitus Handicap Inventory (THI) before they received the individualized customized multi-compound sound therapy for 3 months. THI were re-evaluated on the 30th day and 90th day after treatment.Result: ①The averaged THI score of these patients before the sound treatment was 24.62±15.65 (n=78). The score dropped significantly to 15.82±13.02 and 13.62 ±10.98 on the 30th day and 90th day after treatment, respectively (P<0.01). ②Patient' s gender, age, and the side of tinnitus has no effect on the sound treatment of tinnitus. ③Of these 78 tinnitus patients, 31 patients who showed "notch " hearing loss and 47 patients without "notch " hearing loss in the P-PTA. The averaged THI score between the patients with and without "notch " showed no statistical difference after the treatment (P>0.05).These data suggested that "notch " hearing loss in P-PTA has no effect on the sound therapy.④Of 31 tinnitus patients with "notch " hearing loss, the tinnitus frequency of 22 cases was at the "notch " hearing loss and that of 9 cases was not at the "notch " hearing loss. Sound treatment showed significant between the former and the latter(P<0.05). After 30 days of treatment, tinnitus frequency of four patients whose tinnitus was not at the notch hearing loss drifted to the "notch " hearing loss frequency. Conclusion: Customized multi-compound sound therapy can reduce the THI score of chronic subjective tinnitus patients.The treatment reduced patient's anxiety and improved their quality of life.Sound treatment showed a better improvement in the patients whose tinnitus frequency was located at their notch hearing loss.

Abstract
Background
Hyperglycemia leading to increased oxidative stress is implicated in the increased risk for the development of macrovascular and microvascular complications in patients with type 1 diabetes mellitus.
Methods and Results
A random subcohort of 349 participants was selected from the
DCCT
/
EDIC
(Diabetes Control and Complications Trial/Epidemiology of Diabetes Interventions and Complications) cohort. This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
The polybrominated diphenyl ether flame retardants decabromodiphenyl ether (BDE-209) and bisphenol A (BPA) are environmental contaminants that can cross the placenta and exert toxicity in the developing fetal nervous system. Copy number variants (CNVs) play a role in a number of genetic disorders and may be implicated in BDE-209/BPA teratogenicity. In this study, we found that BDE-209 and/or BPA exposure decreased neural differentiation efficiency of human embryonic stem cells (hESCs), although there was a >90% induction of neuronal progenitor cells (NPCs) from exposed hESCs. However, the mean of CNV numbers in the NPCs with BDE-209 + BPA treatment was significantly higher compared to the other groups, whereas DNA methylation was lower and DNA methyltransferase(DNMT1 and DNMT3A) expression were significantly decreased in all of the BDE-209 and/or BPA treatment groups compared with the control groups. The number of CNVs in chromosomes 3, 4, 11, 22, and X in NPCs with BDE-209 and/or BPA exposure was higher compared to the control group. In addition, CNVs in chromosomes 7, 8, 14, and 16 were stable in hESCs and hESCs-derived NPCs irrespective of BDE-209/BPA exposure, and CNVs in chromosomes 20 q11.21 and 16 p13.11 might be induced by neural differentiation. Thus, BDE-209/BPA exposure emerges as a potential source of CNVs distinct from neural differentiation by itself. BDE-209 and/or BPA exposure may cause genomic instability in cultured stem cells via reduced activity of DNA methyltransferase, suggesting a new mechanism of human embryonic neurodevelopmental toxicity caused by this class of environmental toxins.

Abstract
In this study, a rapid and specific assay for the detection of porcine circovirus type 3 (PCV3) was established using loop-mediated isothermal amplification (LAMP). Four primers were specifically designed to amplify PCV3. The LAMP assay was effectively optimized to amplify PCV3 by water bath at 60°C for 60 min. The detection limit was approximately 1 × 101 copy in this LAMP assay. Compared to porcine circovirus type 2 (PCV2), both gE and gD genes of pseudorabies virus (PRV) and porcine parvovirus (PPV), the LAMP assay showed a high specific detection of PCV3. A visible detection method was developed using SYBR Green I to recognize the results rapidly. Based on the detection of 20 clinical tissue samples, the LAMP assay was more practical and convenient than classical PCR due to its simplicity, high sensitivity, rapidity, specificity, visibility and cost efficiency.

Abstract
OBJECTIVE To explore the effects of recombinant human growth hormone (rHGH) on the survival of the mouse slender narrow pedicle flap and the expressions of vascular endothelial growth factor (VEGF) and classification determinant 34 (CD34). MATERIALS AND METHODS A total of 20 BALB/c mice were randomly divided into the experimental group (n=10) and control group (n=10). The flaps were transplanted for mice in two groups respectively. 6 h after the operation, the mice in the experimental group were administrated with rHGH via local subcutaneous injection, while the mice in the control group were injected with the same amount of normal saline. The laser Doppler was used to measure the sub-flap blood flow rates before the operation, and 3 days, 7 days and 14 days after the operation, respectively; the flap necrosis and survival areas of mice in two groups were measured respectively, and the survival rate of the flap was calculated 14 days after the operation. Afterwards, the flaps of mice in two groups were exfoliated and the shape and structure of flap tissues were tested by the hematoxylin-eosin (HE) staining. Reverse transcription-polymerase chain reaction (RT-PCR) and Western blot were used to test the levels of mRNA and protein of VEGF and CD34 in the flap tissues. RESULTS The flaps of mice in the control group mainly exhibited the black or grayish-black and lost the elasticity with the hard texture, while those in the experimental group were ruddy in color with favorable elasticity. The survival rate of flaps of mice in the experimental group was significantly higher than that in the control group (83.61 ± 12.56% vs. 46.25 ± 9.70%) and the necrosis area of flaps of mice in the experimental group was significantly smaller than that in the control group (1.32 ± 0.16 vs. 4.13 ± 0.35, p < 0.05). There were no statistical differences in the blood flow rates of mouse flap both before the operation and three days after the operation between two groups (p > 0.05), while the blood flow rates of mouse flap both 7 days and 3 days after the operation in the experimental group were higher than those in the control group (p > 0.05). Compared with those in the control group, the levels of VEGF and CD34 were significantly increased, but the levels of the inflammatory factors of the interleukin-6 (IL-6) and tumor necrosis factor-α (TNF-α) were significantly decreased (p < 0.05). CONCLUSIONS rHGH plays an active role in the survival of the flap through promoting the angiogenesis and inhibiting inflammatory reaction.

Abstract
Objective: To investigate the effects of non-muscle myosin ⅡA (NMⅡA) silenced bone marrow mesenchymal stem cells (BMSCs) on the lung damage of rats at early stage of smoke inhalation injury. Methods: Forty Sprague-Dawley rats were divided into control, simple injury, NMⅡA-BMSCs, and BMSCs groups according to the completely random method, with 10 rats in each group. Rats in control group inhaled air normally, while rats in the latter 3 groups inhaled smoke to reproduce model of smoke inhalation injury. At 30 min post injury, rats in simple injury group were injected with 1 mL normal saline via caudal vein, and rats in group BMSCs were injected with 1 mL the fifth passage of BMSCs (1×10(7)/mL), and rats in group NMⅡA-BMSCs were injected with 1 mL NMⅡA silenced BMSCs (1×10(7)/mL). At post injury hour (PIH) 24, abdominal aorta blood and right lung of rats in each group were harvested, and then arterial partial pressure of oxygen (PaO(2)), arterial partial pressure of carbon dioxide (PaCO(2)), and pH value were detected by blood gas analyzer. Ratio of wet to dry weight of lung was determined by dry-wet weight method. Pathological changes of lung were observed with HE staining. Bronchoalveolar lavage fluid (BALF) were collected, and then tumor necrotic factor-α (TNF-α) and interleukin-10 (IL-10) content of BALF was determined by enzyme-linked immunosorbent assay. Data were processed with one-way analysis of variance, Kruskal-Wallis H test, and least-significant difference test. Results: (1) At PIH 24, compared with those in control group, PaO(2) values of rats in simple injury, BMSCs, and NMⅡA-BMSCs groups were obviously decreased (with P values below 0.05), and PaCO(2) values were obviously increased (with P values below 0.05). Compared with those in simple injury group, PaO(2) values of rats in groups NMⅡA-BMSCs and BMSCs were obviously increased (with P values below 0.05), while PaCO(2) values were obviously decreased (with P values below 0.05). PaO(2) value of rats in group NMⅡA-BMSCs was obviously increased as compared with that in group BMSCs (P<0.05). The pH value of arterial blood of rats in simple injury group was obviously lower than that in control group (P<0.05). (2) At PIH 24, ratios of wet to dry weight of lung of rats in control, simple injury, BMSCs, and NMⅡA-BMSCs groups were 4.36±0.15, 7.79±0.42, 5.77±0.18, and 5.11±0.20, respectively. Compared with that in control group, ratio of wet to dry weight of lung of rats was obviously increased in the other 3 groups (with P values below 0.05). Compared with that in simple injury group, ratio of wet to dry weight of lung of rats was obviously decreased in groups BMSCs and NMⅡA-BMSCs (with P values below 0.05). Compared with that in group BMSCs, ratio of wet to dry weight of lung of rats in group NMⅡA-BMSCs was obviously decreased (P<0.05). (3) At PIH 24, alveolar structure of rats in control group was complete without abnormality. Compared with those in simple injury group, lung injury and infiltration of inflammatory cells of rats in groups BMSCs and NMⅡA-BMSCs were obviously alleviated, and alveolar structure was relatively complete with no thickening of alveolar wall. (4) At PIH 24, compared with that in control group, TNF-α content of BALF of rats in simple injury and BMSCs groups was obviously increased (with P values below 0.05). Compared with that in simple injury group, TNF-α content of BALF in groups BMSCs and NMⅡA-BMSCs was obviously decreased (with P values below 0.05). Compared with that in control group, IL-10 content of BALF in simple injury, NMⅡA-BMSCs and BMSCs groups were obviously increased (with P values below 0.05). Compared with that in simple injury group, IL-10 content of BALF in groups BMSCs and NMⅡA-BMSCs was obviously increased (with P values below 0.05). Compared with that in group BMSCs, IL-10 content of BALF in group NMⅡA-BMSCs was obviously increased (P<0.05). Conclusions: NMⅡA silenced BMSCs can alleviate lung damage of rats at early stage of smoke inhalation injury, showing better effectiveness than using BMSCs only.

Characterisation of flower colouration in 30 Rhododendron species via anthocyanin and flavonol identification and quantitative traits. PLANT BIOLOGY (STUTTGART, GERMANY) 2018; 20:121-129.

Abstract
Floral colour is a key reproductive character, often associated with environmental adaptation, and subject to human intervention. A large number of Rhododendron species differ widely in flower colour, providing a good model for flower colouration. The chromatic features and anthocyanin compositions of 30 species from seven subgenera were systematically analysed. The Royal Horticultural Society Colour Chart and CIE L*a*b* system were employed to describe and investigate flower colours. The UPLC-PDA/ESI-MSn system was used to identify and quantify anthocyanins in petal extracts. The flower colours of 30 Rhododendron species were categorised into four groups - red, purplish pink, purple and white. Seven anthocyanins were identified and quantified in petals: delphinidin, cyanidin and malvidin 3-O-arabinoside-5-O-glucosides, cyanidin 3,5-di-O-glucoside, 3-O-galactoside and 3-O-arabinoside, and delphinidin 3-O-glucoside. The red-flowered species mainly contained cyanidin monoglycosides and had much higher total anthocyanin content than purplish pink- and purple-flowered species. Purplish pink- and purple-flowered species had similar anthocyanin types and content. The chromatic differences were significant among groups, except the purplish pink and purple groups. Statistical analysis showed that Cy3Gal and Cy3Arb are characteristic for red-flowered species, and Mv3Arb5G and Dp3Arb5G play important roles in purple colouration; their contents were major components that greatly affected the chromatic parameters. In total, 21 flavonol derivates were identified. However, total flavonol content and co-pigmentation index showed no significant difference or correlation among/with colour groups, suggesting that flavonols might not play a major role in colouration. These results enhance our knowledge of the biochemical basis of flower colouration in Rhododendron species, and provide a foundation for genetic variation studies and aid in breeding cultivars with novel flower colours.

Abstract
In this study, the co-infection of Torque teno sus virus (TTSuV) and porcine circovirus type 3 (PCV3) was reported. One hundred and ten of 132 (83.3%) PCV3-positive samples were co-infected with Torque teno sus virus 1 (TTSuV1). Ninety-four of 132 (71.2%) PCV3-positive samples were co-infected with Torque teno sus virus 2 (TTSuV2). Sixty-six of 132 (50.0%) of PCV3-positive samples were co-infected with both TTSuV1 and TTSuV2. There were no clinical signs of infection in pigs that were both PCV3-positive and PCV2-negative, in either multiparous sows or live-born infants. The high co-infection rate provides valuable information for the further study of the pathological correlation between PCV3 and TTSuVs.

Abstract
Measurements of the associated production of a Z boson with at least one jet originating from a b quark in proton-proton collisions ats = 8 TeV are presented. Differential cross sections are measured with data collected by the CMS experiment corresponding to an integrated luminosity of 19.8fb - 1 . Z bosons are reconstructed through their decays to electrons and muons. Cross sections are measured as a function of observables characterizing the kinematics of the b jet and the Z boson. Ratios of differential cross sections for the associated production with at least one b jet to the associated production with any jet are also presented. The production of a Z boson with at least two b jets is investigated, and differential cross sections are measured for the dijet system. Results are compared to theoretical predictions, testing two different flavour schemes for the choice of initial-state partons.

Abstract
OBJECTIVE To establish SD rat posterior capsular opacification (posterior capsular opacification- PCO) animal model, and to detect the expression of Akt/NF-kb signaling pathway in the PCO model. METHODS 30 healthy SD rats were randomly divided into control group (0d) and the experimental groups (7d and 14 d), there were 10 rats at all time points. All rats (right eye) were treated with the lens capsule, and the inflammatory reaction of the anterior segment of the eye and the occurrence of PCO at different time points were observed under the microscope. The TGF-β concentration of humor aquosus was measured at the different time points by ELISA method. Eyeballs were removed after the rats were killed. RT-PCR method was used to detect the gene expression levels of Akt and NF-κb and Westen Blot method to detect the protein expression of Akt, p-Akt, NF-κb and p-NF-κb. RESULTS TGF-β concentration, Akt and NF-κb gene expression, and Akt, p-Akt, NF-κb and p-NF-κb protein expression in humor aquosus, increased with the time and the time-dependence was significant. CONCLUSION Akt/NF-κb signaling pathway may be closely related to the occurrence and development of PCO, which may be related to the role of protein phosphorylation (Fig. 5, Ref. 20).

BACKGROUND Different from rhinoliths, the paranasal gossypiboma is a foreign body, such as a surgical sponge, left in the nasal cavity. It is a rare, frequently misdiagnosed disease that has rarely been reported. We summarize its clinical characteristics, management, and possible risk factors. METHODOLOGY We reviewed medical records of confirmed paranasal gossypibomas at a tertiary medical center between 2005 and 2015. Clinical symptoms, age, sex, anatomic sites, endoscopic photography, computed tomography, intraoperative findings, and past medical history were reviewed. RESULTS The study included 21 patients, each of whom had ultimately undergone two operations. Among them, 20 underwent endoscopic nasal surgery in primary hospitals, and 15 had been misdiagnosed during the second surgery. The average interval to discovery of a retained foreign body was 200 days. Predominant occurrence sites were the maxillary and ethmoid sinuses. Computed tomography showed paranasal gossypiboma as a heterogeneous cystic lesion with a thin calcified shell. CONCLUSIONS A history of endoscopic nasal surgery, especially performed at a primary hospital, is a warning sign for clinicians. Computed tomography can add to the warning by showing a heterogeneous cystic lesion with a thin calcified shell. Clinicians should be aware of these characteristics to avoid misdiagnosing paranasal gossypiboma.

Validation of EORTC QLQ-OES18 for Chinese patients with esophageal cancer. Dis Esophagus 2017; 30:1-7. [PMID: 28859386 DOI: 10.1093/dote/dox046] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/09/2016] [Accepted: 04/06/2017] [Indexed: 02/06/2023]
Abstract
The aim of this study is to evaluate the reliability, validity, and acceptability of the Chinese version of the EORTC QLQ-OES18 in patients with esophageal cancer. The questionnaire was translated according to the guideline of the EORTC. One hundred and forty-nine patients with esophageal cancer from Tianjin Medical University Cancer Institute and Hospital completed the Karnofsky performance scale (KPS) and the simplified Chinese EORTC QLQ-C30/OES18 scales during July 2013 to January 2014. The results were statistically analyzed by Cronbach's α coefficient, Spearman correlation test with multiple strengthen analysis, and Wilcoxon Rank Sum test. The internal consistency (Cronbach's α coefficient) of all four scales (dysphagia, eating, reflux, and pain) was 0.689-0.822, which were satisfactory or near satisfactory. The absolute values of correlation of each scale between EORTC QLQ-OES18 and EORTC QLQ-C30 were 0.002-0.750 while there was no significant difference between groups divided by KPS scores. We confirmed the Chinese version of EORTC QLQ-OES18 appears to be a reliable, valid, and acceptable instrument for measuring the health-related quality of life of patients with esophageal cancer in mainland China.

Short-term effects of extracorporeal shock wave therapy on bone mineral density in postmenopausal osteoporotic patients. Osteoporos Int 2017; 28:2945-2953. [PMID: 28685283 DOI: 10.1007/s00198-017-4136-7] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/13/2017] [Accepted: 06/21/2017] [Indexed: 11/27/2022]
Abstract
UNLABELLED It has been proved that extracorporeal shock wave therapy (ESWT) could promote new bone formation. Therefore, we designed an experiment to test the efficiency of ESWT on BMD in postmenopausal osteoporotic patients. The results showed that ESWT could effectively improve the local bone mass of the treated bone area within a short duration. INTRODUCTION This study evaluated the short-term effectiveness of extracorporeal shock wave therapy (ESWT) on bone mineral density (BMD). METHODS A total of 64 postmenopausal osteoporotic patients were recruited and randomized into 3 groups in 2015. Groups A (n = 20) and B (n = 21) patients received a single-session of low- or high-energy flux density (EFD) ESWT in the left hip, respectively, whereas group C (n = 23) patients served as controls without the ESWT treatment. All patients self-administered alendronate sodium tablets orally for a year. The BMD of the lumbar spine (L2-L4), femoral neck, great tuberosity, and total left hip was measured before ESWT treatment and at 3, 6, and 12 months using dual energy X-ray absorptiometry (DEXA). RESULTS At 12 months, the lumbar spine, femoral neck, great tuberosity, and total left hip BMD in all patients had increased (p < 0.01). The increase in lumbar spine BMD in group A patients was higher than that in group B patients (p = 0.03); other between-group differences were not observed (p = 0.73, group A vs. C; p = 0.06, group B vs. C). The femoral neck, great tuberosity, and total left hip BMD increases in group B patients were higher than that in either group A or C (p < 0.01, group B vs. A; p < 0.01, group A vs. C). CONCLUSION This study showed that ESWT could efficiently improve the local BMD; relatively, the high dosage was effective.

Abstract
Objective: To investigate the safety and efficacy of radiofrequency ablation (RFA) with percutaneous iohexol-ethanol injection (PIEI), compared with RFA plus transcatheter arterial chemoembolization (TACE) for patients with primary liver cancer(PLC)in high-risk locations. Methods: From January 2012 to December 2014, 54 patients with PLC in high-risk locations were enrolled. They were divided into Group A (RFA combined with PIEI) and Group B (RFA plus TACE). The efficacy and adverse events were assessed. Results: 54 patients had 74 lesions in high-risk locations. There were 26 cases with 40 lesions in Group A, and 28 cases with 34 lesions in Group B. The complete ablation rate of Group A was significantly higher than that of Group B (92.5% vs 70.6%, P=0.014). The two-year local tumor progressionrateand two-year overall survival rate were similar between these two groups (Group A 20.0% vs Group B 38.2%, P=0.083; 90.3% vs 84.3%, P=0.523). Furthermore, the surgery-related severe adverse events of Group A (7.1%, one case of liver abscess and one case ofhematobilia) were more common than that of Group B (0%, P=0.491). No significant differences were found in common adverse events including fever, pain, elevation of aminotransferase and bilirubin. Conclusions: Compared with RFA plus TACE, RFA plus PIEI resulted inbetter complete ablation rate in patients with primary liver cancer in high risk locations. Prospective, randomized, controlled trials are warranted for further evaluation.

Epidemiological investigation of outbreaks of fowl adenovirus infections in commercial chickens in China. Transbound Emerg Dis 2017; 65:e121-e126.

Abstract
One hundred and five fowl adenovirus (FAdV) strains were isolated in China from 2015 to 2016 from poultry with inclusion body hepatitis (IBH) and hydropericardium syndrome (HPS). Polymerase chain reactions determined that 68 were FAdV species C, five were FAdV species D, two were FAdV species E, and 30 contained two or more different FAdV strains. A phylogenetic analysis showed that the isolated FAdV strains clustered into three major groups: FAdV-C, FAdV-D and FAdV-E. Based on a hexon gene sequencing analysis, these viruses were genetically related to FAdV-4, FAdV-7, FAdV-8b and FAdV-11, of which FAdV-4 was dominant (93% of the strains). An epidemiological analysis showed that FAdVs had been circulating in broilers, domestic chickens, and layers, and co-infections with other immunosuppressive pathogens, such as chicken infectious anaemia virus, Marek's disease virus and reticuloendotheliosis virus, were identified. To control FAdVs, strict biosecurity protection measures are necessary, and a continued surveillance of FAdVs is needed to increase our understanding of the epidemiology of the viruses that are associated with IBH and HPS.

Hepatic cyclooxygenase-2 overexpression induced spontaneous hepatocellular carcinoma formation in mice. Oncogene 2017; 36:4415-4426. [PMID: 28346420 PMCID: PMC5543258 DOI: 10.1038/onc.2017.73] [Citation(s) in RCA: 75] [Impact Index Per Article: 10.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2016] [Revised: 02/07/2017] [Accepted: 02/07/2017] [Indexed: 12/12/2022]
Abstract
Cyclooxygenase (COX)-2 is upregulated in hepatocellular carcinoma (HCC). However, the direct causative effect of COX-2 in spontaneous HCC formation remains unknown. We thus investigate the role and molecular pathogenesis of COX-2 in HCC by using liver-specific COX-2 transgenic (TG) mice. We found spontaneous HCC formation with elevated inflammatory infiltrates and neovessels in male TG mice (3/21, 14.3%), but not in any of male WT mice (0/19). Reduced representation bisulfite sequencing (RRBS) and gene expression microarrays were performed in the HCC tumor and non-HCC liver tissues to investigate the molecular mechanisms of COX-2-driven HCC. By RRBS, DNA promoter hypermethylation was identified in HCC from TG mice. Induction of promoter hypermethylation was associated with reduced tet methylcytosine dioxygenase 1 (TET1) expression by COX-2. TET1 could catalyze the conversion of 5-methylcytosine into 5-hydroxymethylcytosine (5hmC) and prevents DNA hypermethylation. In keeping with this, loss of 5hmC was demonstrated in COX-2-induced HCC. Consistently, COX-2 overexpression in human HCC cell lines could reduce both TET1 expression and 5hmc levels. Integrative analyses of DNA methylation and gene expression profiles further identified significantly downregulated genes including LTBP1, ADCY5 and PRKCZ by promoter methylation in COX-2-induced HCC. Reduced expression of LTBP1, ADCY5 and PRKCZ by promoter hypermethylation was further validated in human HCCs. Bio-functional investigation revealed that LTBP1 inhibited cell proliferation in HCC cell lines, suggesting its potential role as a tumor suppressor in HCC. Gene expression microarrays revealed that signaling cascades (AKT (protein kinase B), STK33 (Serine/Threonine kinase 33) and MTOR (mechanistic target of rapamycin) pathways) were enriched in COX-2-induced HCC. In conclusion, this study demonstrated for the first time that enhanced COX-2 expression in hepatocytes is sufficient to induce HCC through inducing promoter hypermethylation by reducing TET1, silencing tumor-suppressive genes and activating key oncogenic pathways. Inhibition of COX-2 represents a mechanism-based target for HCC prevention.
