As a potential vectored vaccine,Newcastle disease virus(NDV)has been subject to various studies for vaccine development,while relatively little research has outlined the immunomodulatory effect of the virus in antigen presentation.To elucidate the key inhibitory factor in regulating the interaction of infected dendritic cells(DCs)and T cells,DCs were pretreated with the NDV vaccine strain LaSota as an inhibitor and stimulated with lipopolysaccharide(LPS)for further detection by enzyme-linked immunosorbent assay(ELISA),flow cytometry,immunoblotting,and quantitative real-time polymerase chain reaction(qRT-PCR).The results revealed that NDV infection resulted in the inhibition of interleukin(IL)-12p40 in DCs through a p38 mitogen-activated protein kinase(MAPK)-dependent manner,thus inhibiting the synthesis of IL-12p70,leading to the reduction in T cell proliferation and the secretion of interferon-γ(IFN-γ),tumor necrosis factor-α(TNF-α),and IL-6 induced by DCs.Consequently,downregulated cytokines accelerated the infection and viral transmission from DCs to T cells.Furthermore,several other strains of NDV also exhibited inhibitory activity.The current study reveals that NDV can modulate the intensity of the innate?adaptive immune cell crosstalk critically toward viral invasion improvement,highlighting a novel mechanism of virus-induced immunosuppression and providing new perspectives on the improvement of NDV-vectored vaccine.

Objective:To establish a model of patellar dislocation by femoral osteotomy or surgical release of medial retinaculum in immature rabbits, and observe morphological and trabecular microarchitectural changes in the trochlea.Methods:Forty rabbits at 3 months of age were included. All right knees underwent surgery, 20 knees were treated with femoral osteotomy and internal rotation of distal femur to increase femoral anteversion angle (Osteotomy group, OS group), and another 20 knees were treated with surgical release of medial retinaculum and overlap suture of lateral retinaculum (Soft tissue group, ST group). All left knees were acting as internal controls. Micro-CT scans for distal femur were acquired after 4 months post surgery. the height of Medial, central, and lateral trochlear, sulcus angle, and lateral and medial trochlear slope were measured to describe the trochlear morphology, and bone volume fraction (BV/TV), trabecular thickness (Tb.Th), trabecular number (Tb.N), trabecular spacing (Tb.Sp), and bone mineral density (BMD) were calculated to evaluate the microarchitectural structure. All parameters were compared between groups.Results:In OS group, one rabbit sustained a hip dislocation without patellar dislocation. Three knees developed complete patellar dislocation in daily flexion position, and the remaining 16 patellae were dislocated when the knee was placed in the maximal extension position. In ST group, 15 knees were complete patellar dislocation in daily flexion position, and 5 knees were without dislocation. A local boss was formed proximal to the entrance of the groove and the articular cartilage was smooth, and no obvious osteoarthritis was observed in OS group. In ST group no boss was formed, while obvious cartilage degeneration and defect was seen. Compared to the control group, the central trochlear height and sulcus angle were greater in both groups, but without significant difference between the two groups. The Tb.Th was increased in both medial and lateral condyle, and Tb.N was decreased in medial condyle compared with its control knees in OS group. The BV/TV, Tb.Th, Tb.N and BMD were decreased and Tb.Sp was increased in both medial and lateral condyle compared with its control knees in ST group. Compared to the OS group, the BV/TV, Tb.Th, Tb.N and BMD were smaller and Tb.Sp was greater in both medial and lateral condyle in ST group, with significant differences.Conclusion:The model of patellar dislocation could be successfully achieved by femoral rotational osteotomy to increase femoral anteversion or surgical release of medial retinaculum and overlap suture of lateral retinaculum, and subsequent morphological and trabecular microarchitectural changes in the trochlea are different. Different bony and soft tissue factors should be addressed for different patients with patellar dislocation in clinical practice.

Objective:To access the independent associations between serum ferritin quintile levels and metabolic syndrome (MS) in adults of different genders.Methods:19 563 participants over the age of 18 years were recruited from "TCLSIH Cohort Study" from 2007 to 2015. Serum ferritin concentration was measured by Enzyme-linked immunoassay, while metabolic syndrome was diagnosed according to MS diagnostic criteria formulated by Chinese Diabetes Society in 2013. Multiple logistic regression analysis was used to assess the association between serum ferritin quintile levels and the prevalence of MS in males and females. Results:After adjusting the confounding factors, the overall prevalence of MS gradually increased with the increasing of serum ferritin levels, similar results were observed in males and females. Subjects were divided into 5 subgroups according to serum ferritin levels. Compared with level 1 group, logistic regression showed that the serum ferritin quintiles of males and females ranged from low to high, the OR (95% confidence interval) for metabolic syndrome were 1.142 (0.998, 1.307), 1.382 (1.210, 1.579), 1.680 (1.472, 1.917), 2.085 (1.827, 2.380), respectively ( Ptrend<0.01), and 1.147 (0.911, 1.444), 1.346 (1.075, 1.687), 1.567 (1.268, 1.941), 2.444 (1.981, 3.023), respectively ( Ptrend<0.01). Conclusion:The elevated ferritin levels were positively related to the prevalence of metabolic syndrome in adults of different genders.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) will reduce the cardiopulmonary function and increase perioperative risk. The aim of this study is to investigate the effect of preoperative short-term high intensity lung rehabilitation training on lung function and postoperative complications in patients with COPD who are eligible for lung cancer surgery. METHODS: We analysis of 101 patients with COPD and a diagnosis of lung cancer, with 43 patients in pulmonary rehabilitation group and 58 patients in conventional group. The pulmonary function, postoperative pulmonary complications (PPCs) and length of stay (LOS) will be compared between the two groups, the lung function will be compared before and after the rehabilitation at the same time. RESULTS: There were no significant difference between the two groups in general information, lung function before surgery, postoperative pulmonary infection [8 (18.6%) vs 17 (29.3%)], atelectasis [1 (2.3%) vs 1 (1.7%)], respiratory failure [1 (2.3%) vs 2 (3.4%)] and postoperative LOS [(8.93±3.78) d vs (9.62±3.98) d, P>0.05]. In the rehabilitation group, the FEV1 [(2.06±0.45) L vs (2.15±0.45) L, P<0.001] and PEF [(4.32±0.90) L/s vs (5.15±1.05) L/s, P<0.001) were higher, and PCO2 [(42.42±2.79) mmHg vs (41.58±2.98) mmHg, P=0.009] was lower after rehabilitation, significantly. The increase value of FEV1 in moderate to severe COPD group was higher than that of the mild COPD group after the rehabilitation [(0.16±0.05) L, 8.6% vs (0.06±0.05) L, 2.8%, P<0.001). CONCLUSIONS The short-term highly-intensity lung rehabilitation can improve lung function in lung cancer patients with COPD, and the improvement of pulmonary function in moderate to severe COPD patients is more obviously.

Objective To summarize the clinical efficacy of renal transplantation from donors of donation after brain death (DBD) complicated with acute kidney injury (AKI). Methods Fifty-nine DBD donors successfully undergoing renal transplantation were recruited in this investigation. According to the Scr level upon admission of intensive care unit (ICU), DBD donors were divided into the AKI group (n=14) and control group (n=45). A total of 101 recipients were assigned into the AKI group (n=23) and control group (n=78) correspondingly. The organ donation conditions of 59 donors were summarized. Main parameters of the donors before organ procurement were statistically compared between two groups. Postoperative kidney function, hospitalization condition and clinical outcomes of the recipients were statistically compared between two groups. Results Among 59 donors, 14 cases (24%) suffered from AKI. Two donors received continuous renal replacement therapy during organ maintenance. Compared with the donors in the control group, the APACHE Ⅱ score of the donors was significantly higher (P<0.05), the incidence of central diabetes insipidus was considerably higher (P<0.01), the Scr levels at admission of ICU and before organ procurement were significantly higher (both P<0.01) and the amount of urine at 24 h before organ procurement was dramatically less in the AKI group (P<0.01).Compared with the recipients in the control group, the Scr levels at postoperative 2 and 3 d were significantly higher (both P<0.05), the length of hospital stay was considerably longer (P<0.01) and the hospitalization expanse was significantly higher in the AKI group (P<0.05). No statistical significance was observed in the postoperative delayed recovery of renal graft function, incidence of acute rejection, infection and rehabilitation dialysis in the recipients between two groups (all P>0.05). At 3 months after transplantation, the recipients in two groups were discharged and the graft survival rate was 100%. Conclusions For renal transplantation from DBD donors complicated with AKI, active measures should be taken to maintain the organ and relieve the AKI, which yields similar clinical efficacy to renal transplantation from non-AKI donors and widens the origin of kidney graft.

Polyacrylamide resin was synthesized via surface-initiated atom transfer radical polymerization ( SI-ATRP) method. Acrylic amide ( AM) was grafted onto the surface of the chloromethyl polystyrene resin via SI-ATRP in the CuBr/2, 2'-bipyridine ( Bpy) system as catalyst at room temperature. The compositions of polyacrylamide resin were determined by means of elementary analysis, FT-IR analysis and scanning electron microscopy ( SEM) . The adsorption properties, the parameters of kinetics and the thermodynamics of the resin were evaluated in details, respectively. As the results, adsorption capacity of 2,4-dichlorophenoxyacetic acid (2,4-D) increased with the initial concentrations of solution increasing at room temperature, and its highest adsorption capacity was 111. 0 mg/g with solution concentration of 8 mmol/L. Adsorption isotherm at room temperature was determined and modeled with Langmuir and Freundlich equations. The thermodynamic equilibrium functions were calculated to be ΔG<0,ΔH=268. 2 kJ/mol, ΔS>0, hence, the adsorption was spontaneous, endothermic and entropy increasing. The kinetics fitted the pseudo-second-order well. The polyacrylamide-chloromethyl polystyrene (PAM-CMCPS) resin was used for the adsorption of 2,4-D in orange sample, and good results were obtained.
