Abstract
The murine monoclonal anti‐idiotypic antibody, NP30, is a potential vaccine candidate against Schistosoma japonicum. Previous studies have revealed that NP30 has an immunoregulatory effect, but the underlying mechanism for this effect remains unknown. This study shows that NP30 induces dendritic cell (DC) maturation and increases the production of pro‐inflammatory cytokines. The expression of CD86 and MHC II was upregulated in DCs following stimulation with NP30 in vitro. Moreover, NP30 induced Th17 polarization by increasing the production of IL‐6 and TGF‐β. In vivo, Th17 differentiation was induced by the production of key pro‐inflammatory cytokines, including IL‐6and TGF‐β, from DCs of NP30‐immunized mice. These results indicate that NP30 promotes Th17 polarization through DC activation, preventing serious schistosomiasis.

Abstract
Simple Summary The transparency of pigeon egg albumen is a special phenotypic trait that different from other poultry eggs, and calcium is one of the main factors. This experiment aimed to study the effects of added dietary Ca on production performance, egg quality, and albumen transparency. It will guide producers on how to feed their laying pigeons and provide a scientific basis for special feed research and the development of laying pigeons with transparent eggs. Abstract In order to confirm the dietary calcium (Ca) requirement to keep a balance of the production performance and the albumen transparency, the study examined the effects of different dietary Ca levels on the production performance, egg quality, and albumen transparency of laying pigeons. 1080 pigeon pairs were randomly allocated into six treatment groups, each consisting of six replicates of 30 pigeon pairs per treatment. Ca levels of 0.60, 0.90, 1.20, 1.80, 2.40, and 3.00% were fed. The results showed that the laying rate, average egg weight, and feed to egg ratio were significantly influenced by Ca levels (p < 0.05). Albumen percentage, albumen height, Haugh unit, and eggshell thickness at 8 w and 16 w were significantly influenced by Ca levels (p < 0.05). The L*, a*, b*, and c* values of cooked albumen at 8 w and 16 w were all significantly influenced by Ca levels (p < 0.05). After 16 w of feeding different Ca levels, the percentage of transparent eggs had an early increasing and later decreasing trend. In conclusion, taking the transparency of pigeon eggs as an assessment index and considering production performance secondly, the optimal level of dietary Ca for laying White King pigeons is 0.90%.

Abstract
Gingival recession could result in root exposure, dental hypersensitivity and poor aesthetics. It has been demonstrated that varieties of root coverage procedures can significantly improve gingival recession in short-term (≤6 months), of which coronally advanced flap combined with connective tissue graft is the gold standard technique for treatment of gingival recession. It could obtain the optimally complete root coverage and maintain long-term stability (≥2 years). However, clinical knowledge about the long-term effectiveness of the other alternative graft materials remain very limited. Based on the existing clinical evidence, this article reviews coronally advanced flap, coronally advanced flap combined with connective tissue graft or alternative graft materials, with particular attention to the long-term stability of them, in order to provide reference for the design of further clinical trials and the plan of clinical treatments.

Abstract
Objective: To produce latent membrane protein 2A (LMP2A) chimeric antigen receptor (CAR)-T cells and detect the lethal effect of LMP2A CAR-T cells on nasopharyngeal carcinoma (NPC) cells. Methods: The study was conducted from September 2016 to December 2017.Genetic engineering technology was used to construct anti-LMP2A CAR lentiviral expression vector and sequencing was identified. The expression of anti-LMP2A CAR in the 293T cells was confirmed by western blot. CCK8 assay was used to evaluate the cytotoxicity of LMP2A CAR-T cells to NPC cells. ELISA assay was performed to test IL-2 and IFN-γ releasing of activated LMP2A CAR-T cells. The inhibition effect of LMP2A CAR-T cells on NPC xenograft tumor was observed in vivo. Statistical analysis was performed by statistical software SPSS 21.0. Results: The results of PCR and sequencing showed that anti-LMP2A CAR lentiviral expression vector was constructed successfully. The result of western blot indicated the expression of anti-LMP2A CAR in the 293T cells effectively. The results of CCK-8 assay showed that the killing activities of LMP2A CAR-T cells to LV-LMP2A-CNE1 cells were (72.11±9.75)%, (54.65 ±5.42)% and (36.68±3.80)% at 20∶1, 10∶1 and 5∶1 ratio of effective cells to target cells, and had a statistical difference compared to CD19 CAR-T cells and T cells (P<0.05). There was no significant difference in the killing activities of LMP2A CAR-T cells to CNE1 cells compared with CD19 CAR-T cells and T cells. The results of ELISA showed that the content of IL-2 and IFN-γ in the co-culture supernatant of LMP2A CAR-T cells and LV-LMP2A-CNE1 cells was significantly higher than that of LMP2A CAR-T cells and CNE1 cells which had statistical difference (P<0.05); In vivo experiment, the volume of LMP2A CAR-T cell group was (80.3±10.0) mm(3) which was significantly lower than that of the control groups, and the difference was statistically significant (P<0.05). Conclusion: LMP2A CAR-T cells are successfully prepared and have an obvious targeting cytotoxicity on LMP2A-positive NPC cells.

Abstract
We present the first experimental evidence supported by simulations of kinetic effects launched in the interpenetration layer between the laser-driven hohlraum plasma bubbles and the corona plasma of the compressed pellet at the Shenguang-III prototype laser facility. Solid plastic capsules were coated with carbon-deuterium layers; as the implosion neutron yield is quenched, DD fusion yield from the corona plasma provides a direct measure of the kinetic effects inside the hohlraum. An anomalous large energy spread of the DD neutron signal (∼282 keV) and anomalous scaling of the neutron yield with the thickness of the carbon-deuterium layers cannot be explained by the hydrodynamic mechanisms. Instead, these results can be attributed to kinetic shocks that arise in the hohlraum-wall-ablator interpenetration region, which result in efficient acceleration of the deuterons (∼28.8 J, 0.45% of the total input laser energy). These studies provide novel insight into the interactions and dynamics of a vacuum hohlraum and near-vacuum hohlraum.

Abstract
Species-specific cusp patterns result from the iterative formation of enamel knots, the epithelial signaling centers, at the future cusp positions. The expressions of fibroblast growth factors (FGFs), especially Fgf4, in the secondary enamel knots in the areas of the future cusp tips are generally used to manifest the appearance of species-specific tooth shapes. However, the mechanism underlying the predictive role of FGFs in species-specific cusp patterns remains obscure. Here, we demonstrated that gerbils, which have a lophodont pattern, exhibit a striped expression pattern of Fgf4, whereas mice, which have a bunodont pattern, have a spotted expression pattern, and these observations verify the predictive role of Fgf4 in species-specific cusp patterns. By manipulating FGFs' signaling in the inner dental epithelium of gerbils, we provide evidence for the intracellular participation of FGF signaling, specifically FGF4 and FGF20, in Rac1- and RhoA-regulated cellular geometry remolding during the determination of different cusp patterns. Our study presents a novel explanation of how different FGF expression patterns produce different cusp patterns and implies that a conserved intracellular FGF-GTPase signaling module might represent an underlying developmental basis for evolutionary changes in cusp patterns.

Abstract
AIM To conduct a systematic review and meta-analysis of randomized controlled trials (RCTs) to evaluate the safety and efficacy of romosozumab in the treatment of postmenopausal osteoporosis. METHOD A comprehensive literature review was performed of PubMed, EMBASE, Cochrane Controlled Trials Registry, and Web of Science for RCTs. Outcome measures were changes in lumbar spine, total hip and femoral neck bone mineral density (BMD), incidence of fractures and adverse events. Six trials were finally included. RESULTS Romosozumab resulted in a significantly lower risk of new vertebral fracture (relative risk (RR) 0.37, 95% confidence interval (CI) 0.18-0.77, p = 0.005, n = 5371), non-vertebral fracture (RR 0.78, 95% CI 0.66-0.92, p < 0.0001, n = 5635) and hip fracture (RR 0.59, 95% CI 0.44-0.79, p = 0.0004, n = 5635) compared with other therapies. The BMD was significantly increased at the lumbar spine (weighted mean difference (WMD) 13.33, 95% CI 11.41-15.25, p < 0.00001, n = 198), total hip (WMD 5.09, 95% CI 3.81-6.38, p < 0.00001, n = 184) and femoral neck (WMD 4.70, 95% CI 3.50-5.90, p < 0.00001, n = 175) compared with placebo. There was no significant difference in the incidence of adverse events in patients with romosozumab compared to other therapies (RR 1.00, 95% CI 0.98-1.02). CONCLUSION In postmenopausal women with osteoporosis who were at high risk for fracture, romosozumab treatment resulted in a significantly lower risk of fracture. Romosozumab 210 mg monthly showed the largest gains in BMD, and was generally well tolerated.

Abstract
Invasive species exert a serious impact on native fauna and flora and have been the target of many eradication and management efforts worldwide. However, a lack of data on population structure and history, exacerbated by the recency of many species introductions, limits the efficiency with which such species can be kept at bay. In this study we generated a novel genome of high assembly quality and genotyped 4735 genome-wide single nucleotide polymorphic (SNP) markers from 78 individuals of an invasive population of the Javan Myna Acridotheres javanicus across the island of Singapore. We inferred limited population subdivision at a micro-geographic level, a genetic patch size (~13-14 km) indicative of a pronounced dispersal ability, and barely an increase in effective population size since introduction despite an increase of four to five orders of magnitude in actual population size, suggesting that low population-genetic diversity following a bottleneck has not impeded establishment success. Landscape genomic analyses identified urban features, such as low-rise neighborhoods, that constitute pronounced barriers to gene flow. Based on our data, we consider an approach targeting the complete eradication of Javan Mynas across Singapore to be unfeasible. Instead, a mixed approach of localized mitigation measures taking into account urban geographic features and planning policy may be the most promising avenue to reducing the adverse impacts of this urban pest. Our study demonstrates how genomic methods can directly inform the management and control of invasive species, even in geographically limited datasets with high gene flow rates.

Abstract
OBJECTIVE To study the application value of artificial skin substitute compositely constructed by adipose-derived stem cells and fibrin gel in skin defect. MATERIALS AND METHODS Adipose-derived stem cells (ADSCs) were obtained from healthy pure green fluorescent protein (GFP) transgenic mice and were proved to have multiple differentiation potentials. They compositely constructed artificial skin substitute in vitro with fibrin gel. 24 SD rats of either gender, with the gestational age of 3-5 weeks, were divided into four groups in the experiment, namely model group (autologous skin flap transplantation), adipose-derived stem cell transplantation group, fibrin gel transplantation group and compound transplantation group, 6 rats for each group. At the skin blood flow (measured by applying laser Doppler rheometer) and survival rate of the flap on 7d and 21d respectively, the materials were transplanted at back skin injury (1 cm×1 cm) to prepare tissue slice for routine HE staining. The conditions of wound healing were observed, and the angiogenesis of flap neovascularization was detected by the immunofluorescent assay. RESULTS The skin blood flow, the survival rate of flap and density of neovascularization 7d and 21d after transplantation were significantly higher than those of stem cell group, followed by the model group, with the lowest ones in the fibrin gel group. The differences had statistical significance (p<0.05). The wound healing time of compound group was significantly shorter than that of stem cell group, followed by the model group, with the longest one in the fibrin gel group. The differences had statistical significance (p<0.05). CONCLUSIONS The artificial skin substitute compositely constructed by adipose-derived stem cells and fibrin gel could significantly shorten healing time and improve the survival rate of the flap in skin defect, with better application value.

Abstract
We investigate a new laser-driven spherically convergent plasma fusion scheme (SCPF) that can produce thermonuclear neutrons stably and efficiently. In the SCPF scheme, laser beams of nanosecond pulse duration and 10^{14}-10^{15} W/cm^{2} intensity uniformly irradiate the fuel layer lined inside a spherical hohlraum. The fuel layer is ablated and heated to expand inwards. Eventually, the hot fuel plasmas converge, collide, merge, and stagnate at the central region, converting most of their kinetic energy to internal energy, forming a thermonuclear fusion fireball. With the assumptions of steady ablation and adiabatic expansion, we theoretically predict the neutron yield Y_{n} to be related to the laser energy E_{L}, the hohlraum radius R_{h}, and the pulse duration τ through a scaling law of Y_{n}∝(E_{L}/R_{h}^{1.2}τ^{0.2})^{2.5}. We have done experiments at the ShengGuangIII-prototype facility to demonstrate the principle of the SCPF scheme. Some important implications are discussed.

Abstract
Objective: To explore the efficacy and safety of tertiary hospital guided and community-driven family self-help cardiac rehabilitation model. Methods: This study was a prospective randomized controlled study, 80 patients from Beijing Electrical Power Hospital and Beijing Jingmei Group General Hospital with acute coronary syndrome were included from June to December 2015 and divided into 2 groups. Patients in rehabilitation group (n=52) received tertiary hospital(Peiking University Peoples' Hospital) guided and community-driven family self-help cardiac rehabilitation for 3 months, and patients in control group (n=28) received routine secondary treatment for 3 months. Following parameters including 6 minutes walk distance, score of life quality (evaluated by Short Form-12), score of anxiety (evaluated by Generalized Anxiety Disorder-7), score of depression (evaluated by Perceived Health Questionnaire-9), self-management competency (evaluated by questionnaire) were collected at baseline and after treatment for 3 months. Results: Compared with control group, 6 minutes walk distance was longer in rehabilitation group((60.2±6.8) meters vs. (24.9±10.5)meters, P<0.01). The difference values between after and before intervention of life quality scores((0.14±3.90)scores vs.(-7.44±5.85)scores, P>0.05), anxiety scores((-0.16±2.12 ) scores vs.(0.70±1.13)scores, P>0.05) and depression scores((-1.17±2.79) scores vs.(0.60±0.36)scores, P>0.05) were similar between the 2 groups. The amplification of patients with regular exercise (50.26% vs. 0, P<0.05), limit sugary foods usually and always (53.22% vs. 3.98%, P<0.05), eat 200-400 g fruits usually and always (78.61 % vs. 0, P<0.05), eat 300-500 g vegetables usually and always (9.74% vs. 0, P<0.05), and answering very confident to questions such as let the physicians know about your diseases (40.17% vs. 5.00%, P<0.05), know how to take medicines (44.52% vs. 5.00%, P<0.05), know how much exercise was right for yourself (26.43% vs.0, P<0.05) were significantly higher in rehabilitation group than in control group. There were no cardiac rehabilitation training related cardiovascular events. Conclusion: Tertiary hospital guided and community-driven family self-help cardiac rehabilitation model is an effective and safe management model of cardiovascular disease in chronic phase, and it is necessary to further expand the study population to verify the efficacy of this model.

Abstract
AIMS To investigate the roles of cyclooxygenases (COX) and their metabolites in C57/BL6 mice with 5/6 nephrectomy, an animal model of chronic renal failure. MAIN METHODS C57/BL6 mice were grouped into sham-operated (2K), one kidney removal (1K) and 5/6 nephrectomy groups (5/6Nx). Renal resistive index was measured by ultrasonography. Blood, aortae, renal arteries and renal cortex were collected for measurement of kidney function, assessment of vascular responsiveness, Western blotting, immuohistochemistry and enzyme-linked immunosorbent assays. KEY FINDINGS After four weeks, acetylcholine-induced relaxations were blunted in renal arteries of 1K and 5/6Nx mice; indomethacin, a non-selective COX inhibitor, improved the response in 5/6Nx, but not in 1K renal arteries. In 5/6Nx renal arteries, but not in 1K preparations, the protein presence of endothelial nitric oxide synthase (eNOS) was decreased, while that of COX-2 and its products [prostacyclin and thromboxane A2] were increased. The renal resistive index was lower in 5/6Nx mice, suggesting a lower resistance in the renal microvasculature. In the renal cortex of 5/6Nx mice, eNOS protein presence was increased; while the presence of COX-2 was not detectable. The prostaglandin E2 level was lower in the 5/6Nx cortex than in the other two groups. SIGNIFICANCE The early stage of renal mass removal is associated with increased renal arterial constriction and reduced microvascular resistance. The former is due to downregulation of eNOS and upregulation of COX-2, leading to an increased production of prostacyclin and thromboxane A2. A reduced production of PGE2 in the renal cortex is important for maintaining normal renal function.

Abstract
Biologically relevant monolayer and bilayer films often consist of micron-scale high viscosity domains in a continuous low viscosity matrix. Here we show that this morphology can cause the overall monolayer fluidity to vary by orders of magnitude over a limited range of monolayer compositions. Modeling the system as a two-dimensional suspension in analogy with classic three-dimensional suspensions of hard spheres in a liquid solvent explains the rheological data with no adjustable parameters. In monolayers with ordered, highly viscous domains dispersed in a continuous low viscosity matrix, the surface viscosity increases as a power law with the area fraction of viscous domains. Changing the phase of the continuous matrix from a disordered fluid phase to a more ordered, condensed phase dramatically changes the overall monolayer viscosity. Small changes in the domain density and/or continuous matrix composition can alter the monolayer viscosity by orders of magnitude.

Abstract
OBJECTIVE The aim of the present study was to evaluate the efficacy of three different modalities in treatment of lung oligometastases from nasopharyngeal carcinoma (NPC) after radiotherapy and to identify a more appropriate treatment modality. METHODS The clinical data of 87 cases of lung oligometastases from NPC were analyzed retrospectively. Among them, 33 patients underwent local small-field irradiation+ /- chemotherapy, 28 underwent whole-lung irradiation+ chemotherapy, and 26 underwent simple chemotherapy. The survival rates were calculated using Kaplan-Meier analysis. The differences among the modalities were evaluated using the log-rank test. Cox univariate and multivariate analyses were performed to determine the influencing factors. RESULTS The 3-year lung metastasis survival (LMS) rates of patients with lung metastasis undergoing the three treatment modalities (local small-field irradiation+ /-chemotherapy, whole-lung irradiation+ chemotherapy and chemotherapy alone) were 89.3%, 72.7%, and 72.4%, respectively, showing a significant difference between the groups (P=0.003). Further subgroup analysis showed that the 5-year LMS rate was significantly higher in the local small-field irradiation+ /-chemotherapy group than that in the whole-lung irradiation+ chemotherapy group and chemotherapy alone group (P=0.001). The 2-year progression-free survival (PFS) rates of the three groups were 57.1%, 25.8% and 3.8%, respectively, showing significant intergroup differences (P=0.002 and P<0.001). Multivariate analysis indicated that compared with the whole lung irradiation group and the chemotherapy alone group, the local irradiation+ /- chemotherapy is an independent favorable prognostic factor for LMS and PFS (P<0.05). CONCLUSION Local radiotherapy combined with systemic chemotherapy is the best therapeutic modality for lung oligometastases derived from NPC after radiotherapy, improving the LMS and prolonging the PFS.

Abstract
OBJECTIVE To evaluate the impacts of clinical, pathological, and laboratory factors on oncological outcomes of patients with T3N0M0 renal cell carcinoma. METHODS The clinical data, laboratory exam results, and follow-up outcomes of 182 patients with T3N0M0 renal cell carcinoma who underwent nephrectomy from 2007 to 2012 in Peking University First Hospital were retrospectively collected. The 5-year cancer-specific survival and 5-year recurrence-free survival of all the patients were calculated using Kaplan-Meier method, and the statistical significance between the survival curves were compared using the Log-rank test. Variables with significant differences in the univariate analysis were subjected to the multivariate analysis by Cox regression model. All the comparisons were conducted using two-tailed test and P<0.05 was considered statistically significant. RESULTS A total of 182 patients were included in this study. Of all the 182 patients, 126 were male (69.23%) and 56 were female (30.77%). The mean age was (56.75±12.45) years. The median follow-up time was 48 months (3-99 months). At the end of the follow-up, 50 patients (27.47%) died due to the disease after a median of 29.74 months and 59 patients (32.42%) had tumor recurrence after a median of 22.12 months. The 5-year cancer-specific survival of all patients was 68.30% (95% CI: 60.16%-75.84%); the 5-year recurrence-free survival was 60.70% (95% CI: 53.16%-68.84%). In the univariate analysis, diabetes mellitus, tumor invasion status, Fuhrman grade, serum album, serum cholestenone, anemia, and neutrophils percentage were associated with the cancer-specific survival and Fuhrman grade, serum album and anemia were associated with the recurrence-free survival. Variables with significant differences on univariate analysis were included in Cox multivariate regression analysis. Multivariate Logistic regression analysis showed that diabetes mellitus (HR=2.434, 95% CI: 1.243-4.769, P=0.010), hypoalbuminemia (HR=2.188, 95% CI: 1.074-1.074, P=0.031), and anemia (HR=3.320, 95% CI: 1.839-5.991, P<0.001) were independent risk factors significantly associated with cancer-specific survival; and higher Fuhrman grade (HR=2.552, 95% CI: 1.433-4.545, P=0.001), anemia (HR=2.535, 95% CI: 1.497-4.293, P=0.001) were independent factors significantly associated with recurrence-free survival. CONCLUSION Diabetes mellitus, hypoalbuminemia, and anemia were independent risk factors significantly associated with cancer-specific survival of T3N0M0 renal cell carcinoma patients; higher Fuhrman grade and anemia were independent risk factors significantly associated with tumor recurrence of T3N0M0 renal cell carcinoma patients.

Abstract
OBJECTIVE To investigate the methylation status of the RASSF1A gene promoter in upper tract urothelial carcinoma (UTUC) tissues and its correlation with clinicopathologic characteristics and postoperative recurrence of primary UTUC. METHODS In a retrospective design, a total of 687 patients who underwent surgeries for primary UTUC in the urology department of Peking University First Hospital were enrolled. The methylation status of the RASSF1A gene promoter was analyzed using methylation-sensitive polymerase chain reaction on tumor specimens. RESULTS Aberrant methylation for the RASSF1A gene promoter was detected in 183 (26.6%) DNA samples in total. Aberrant methylation of the RASSF1A gene was strongly associated with tobacco consumption (P=0.044), ipsilateral hydronephrosis (P<0.001 ), tumor location (P<0.001 ), tumor stage (P=0.001), tumor grade (P=0.007), lymph node metastasis (P=0.001) and growth pattern (P=0.013). The methylated RASSF1A gene promoter was an independent risk factor for bladder recurrence (P<0.001, HR=0.471) and contralateral recurrence (P=0.030, HR=0.269) of UTUC after surgery. Hypermethylated RASSF1A was predictive for improved bladder recurrence-free survival (BRFS) (P<0.001) and contralateral recurrence-free survival (CRFS) (P=0.021) in the UTUC patients. Compared with the patients with unmethylated RASSF1A, the patients containing tumors with hypermethylated RASSF1A had tendency toward longer recurrence-free survival time [(114.4±3.9) months vs. (84.0±3.2) months for BRFS, (138.1±1.8) months vs. (132.9±1.9) months for CRFS] and higher estimated cumulative recurrence-free survive rates ( five-year survival rate for example, 79.8%±3.4% vs. 57.4%±2.6% for BRFS, 98.9%±0.8% vs. 93.0%±1.4% for CRFS). Additionally, tumor multifocality (P=0.002, HR=1.538), and ureteroscopy before surgery (P=0.001, HR=1.725) were independent risk factors for bladder recurrence in postoperative UTUC patients. CONCLUSION The methylation status of the RASSF1A gene promoter appears to be a promising epigenomic biomarker for assessing the aggressiveness of UTUC and a predictor predicting the urinary tract recurrence after surgery.
