Oral Administration Following Subcutaneous Administration of FCV Vaccines Enhances Vaccine Efficacy against Challenge of a Highly Virulent Vs Feline Calicivirus

Feline calicivirus (FCV) is a common cause of upper respiratory and oral disease in cats. Highly virulent systemic strains of FCV (vs FCV) have been described. These vs FCV isolates cause characteristic edema, cutaneous ulcers and other clinical signs typically associated with FCV infection. Vs FCV isolates also cause high mortality even in previously vaccinated cats. We reported previously that the FCV serum cross-neutralization profile of cat serum generated using the oralnasal route of administration is broader than with subcutaneous administration (SC), as measured with a 26-FCV viral panel (Rong et al., Virus Research 122:95-108, 2006). In this report, we tested the in vivo ef- ficacy of the FCV vaccine, in a 4-way (FCV-FHV-FPV-FCp) format, by using a highly virulent vs FCV- 33585 as the challenge virus. Vaccines were administered as 2-dose subcutaneouly (SC/SC), or subcutaneously followed by orally (SC/Oral). The mortality induced by vs FCV-33585 in unvaccinated control cats was 78% (7 out of 9 cats). The mortality decreased to 44% (4 out of 9 cats) with cats vaccinated with the 4-way vaccine given SC/SC. However, when this vaccine was given SC/Oral, the mortality decreased to 10% (1 out of 10 cats). The clinical scores, calculated based on frequency and severity of various clinical signs, correlated with mortality data. These results demonstrated that oral administration of FCV vaccines, as the second dose following the first dose of subcutaneious administration, ehances FCV efficacy against challenge of a highly virulent vs FCV. We propose that not only oral vaccination offers convenience and needle-free inoculation, it also enhances FCV vaccine efficacy.

The construction of in vitro nasal cavity-mimic M-cell model,design of M cell-targeting nanoparticles and evaluation of mucosal vaccination by nasal administration

In order to better evaluate the transport effect of nanoparticles through the nasal mucosa,an in vitro nasal cavity-mimic model was designed based on M cells.The differentiation of M cells was induced by co-culture of Calu-3 and Raji cells in invert model.The ZO-1 protein staining and the transport of fluorescein sodium and dexamethasone showed that the inverted co-culture model formed a dense monolayer and possessed the transport ability.The differentiation of M cells was observed by upregulated expression of Sialyl Lewis A antigen(SLAA)and integrinβ1,and down-regulated activity of alkaline phosphatase.After targeting M cells with iRGD peptide(cRGDKGPDC),the transport of nanoparticles increased.In vivo,the co-administration of iRGD could result in the increase of nanoparticles transported to the brain through the nasal cavity after intranasal administration.In the evaluation of immune effect in vivo,the nasal administration of OVA-PLGA/iRGD led to more release of IgG,IFN-γ,IL-2 and secretory IgA(sIgA)compared with OVA@PLGA group.Collectively,the study constructed in vitro M cell model,and proved the enhanced effect of targeting towards M cell with iRGD on improving nasal immunity.

Optimal dosing time of Dachengqi decoction for protection of extrapancreatic organs in rats with experimental acute pancreatitis

BACKGROUND Acute pancreatitis(AP)is a pancreatic inflammatory disorder that is commonly complicated by extrapancreatic organ dysfunction.Dachengqi decoction(DCQD)has a potential role in protecting the extrapancreatic organs,but the optimal oral administration time remains unclear.AIM To screen the appropriate oral administration time of DCQD for the protection of extrapancreatic organs based on the pharmacokinetics and pharmacodynamics of AP rats.METHODS This study consisted of two parts.In the first part,24 rats were divided into a sham-operated group and three model groups.The four groups were intragastrically administered with DCQD(10 g/kg)at 4 h,4 h,12 h,and 24 h postoperatively,respectively.Tail vein blood was taken at nine time points after administration,and then the rats were euthanized and the extrapancreatic organ tissues were immediately collected.Finally,the concentrations of the major DCQD components in all samples were detected.In the second part,84 rats were divided into a sham-operated group,as well as 4 h,12 h,and 24 h treatment groups and corresponding control groups(4 h,12 h,and 24 h control groups).Rats in the treatment groups were intragastrically administered with DCQD(10 g/kg)at 4 h,12 h,and 24 h postoperatively,respectively,and rats in the control groups were administered with normal saline at the same time points.Then,six rats from each group were euthanized at 4 h and 24 h after administration.Serum amylase and inflammatory mediators,and pathological scores of extrapancreatic organ tissues were evaluated.RESULTS For part one,the pharmacokinetic parameters(C max,T max,T 1/2,and AUC 0→t)of the major DCQD components and the tissue distribution of most DCQD components were better when administering DCQD at the later(12 h and 24 h)time points.For part two,delayed administration of DCQD resulted in lower IL-6 and amylase levels and relatively higher IL-10 levels,and pathological injury of extrapancreatic organ tissues was slightly less at 4 h after administration,while the results were similar between the treatment and corresponding control groups at 24 h after administration.CONCLUSION Delayed administration of DCQD might reduce pancreatic exocrine secretions and ameliorate pathological injury in the extrapancreatic organs of AP rats,demonstrating that the late time is the optimal dosing time.

Testing for hepatitis B virus alone does not increase vaccine coverage in non-immunized persons

AIM To determine whether hepatitis B virus(HBV)-testing could serve as a gateway to vaccinate non-immunized individuals in a low-prevalent country.METHODS Non-immunized subjects participating in a multi-center, HBV-testing campaign in Paris, France were identified and contacted via telephone 3-9 mo after testing in order to determine vaccination status. Vaccination coverage was evaluated in per-protocol(for all respondents) and intent-to-treat analysis(assuming all non-responders did not vaccinate).RESULTS In total, 1215/4924(24.7%) enrolled subjects with complete HBV serology were identified as nonimmunized and eligible for analysis. There were 99/902 successfully contacted subjects who had initiated HBV vaccination after screening: per-protocol, 11.0%(95%CI: 9.0-13.2); intent-to-treat, 8.2%(95%CI: 6.7-9.8). In multivariable analysis, vaccination was more likely to be initiated in individuals originating from moderate or high HBV-endemic countries(P < 0.001), patients with limited healthcare coverage(P = 0.01) and men who have sex with men(P = 0.02). When asked about the reasons for not initiating HBV vaccination, the most frequent response was "will be vaccinated later"(33.4%), followed by "did not want to vaccinate"(29.8%), and "vaccination was not proposed by the physician"(21.5%). Sub-group analysis indicated a stark contrast in vaccination coverage across centers, ranging from 0%-56%.CONCLUSION HBV-vaccination after HBV screening was very low in this study, which appeared largely attributed to physician-patient motivation towards vaccination. Increased vaccination coverage might be achieved by emphasizing its need at the organizational level.

Enhancement of Humoral Immune Response of Newcastle Disease Vaccine by ATRA

[ Objective] The paper was to study the immune enhancement of ATRA on Newcastle Disease （ND） vaccine. [ Method ] The 1-day-old AA broilers were treated with ATRA at the doses of I and 5 p.mol/kg, respectively. At 7 and 28 days of age, broilers in drug control group, low dose group and high dose group were immunized with ND vaccine by intranasal and eye immunization approach. At 7, 14, 21, 28, 35, 42 and 49 clays of age, seven chickens were randomly se- lected from each group and weighed. The thymus, spleen, bursa of fabrieius and serum were collected for calculating immune organ index of thymus, spleen and bursa of fabricius. The ND specific antibody titers in serum were determined with HI test. [Result] ATRA promoted the growth of thymus, spleen and bursa of fabricius, and improved the immune organ index and ND specific antibody titers of chicks. [ Conclusion] ATRA enhanced the humoral immune response of chicks, and ATRT at the dose of 5 μmol/kg presented more prominent immune enhancement effect on ND vaccine.

论公共卫生治理的政府责任

多元共治时代,公共卫生治理中政府责任要打破基于行政任务进行责任配置的传统逻辑,将政府责任的厘定置于“公共任务公私合作”和“行政任务公私合作”的双重视域。公共卫生治理中行政机关作为公共任务公私合作的主导者和行政任务公私合作的责任方,在承担领导与促进责任、组织与动员责任、履行或担保责任、监督与救济责任之时,其内部构造差异明显。新时代公共卫生治理体系建构必须着眼于中国式社会治理共同体这一整体性视角,科学厘定公共卫生治理中政府责任的内部法律构造,统筹推动公共卫生治理法治化进程。

高校高水平运动队建设路径的逻辑辨识与行动方略——基于行政型体育组织的考察

从组织管理过程的基本属性行政化入手,依托结构功能主义与组织行为学观点,以个体行动作为逻辑起点,对我国高校高水平运动队实践样态加以剖判并进行类型学建构,归纳其在宏观、中观和微观层面的3类建设路径,由此判辨各路径在建设过程中存在的问题,再结合“制度-利益-观念”概念性框架对其进行消解,进而探索高校高水平运动队未来的行动方略。研究认为,我国高校高水平运动队主要呈现出“层层加码”“水平比码”“主体择码”3类建设路径,且分别存在制度环境的行政力量产生锁入效应、高校职能部门间利益分配的非帕累托改变、行政官员对多重建设目标的选择偏颇问题,而这可从制度的规范引导、利益的有效激励和观念的柔性约束3个方面对其进行改善。

鱼类鼻黏膜相关淋巴组织的研究进展

鱼类黏膜相关淋巴组织是抵御病原入侵的第一道防线。其中,鱼类鼻黏膜相关淋巴组织(nasal-associated lymphoid tissue,NALT)近年来被国内外学者所关注,并被证明是嗅觉器官中抗原识别和启动黏膜免疫应答的重要场所,在细菌、病毒和寄生虫感染后可发挥快速的局部免疫响应。以NALT为靶点,对鱼类开展疫苗鼻内接种可起到良好的免疫保护效果。但目前,对NALT中复杂的免疫细胞与分子网络及其互作机制知之甚少。本文对鱼类嗅觉器官结构与功能、NALT的细胞与分子网络及免疫应答、鼻内接种的应答及免疫保护效果等方面的最新研究进展进行综述,旨在阐明鱼类NALT在黏膜局部发挥的免疫防御机制,以期为新型黏膜疫苗的设计与研发提供参考。
