Abstract
Objective: To analyze the epidemiological characteristics of mumps in 2012 and 2014, and to explore the preventive effect of the second dose of mumps-containing vaccine (MuCV) in mumps in Shandong province. Methods: On the basis of certain model assumptions, a Space State model was formulated. Iterated Filter was applied to the epidemic model to estimate the parameters. Results: The basic reproduction number (R(0)) for children in schools was 4.49 (95%CI: 4.30-4.67) and 2.50 (95%CI: 2.38-2.61) respectively for the year of 2012 and 2014. Conclusions: Space State model seems suitable for mumps prevalence description. The policy of 2-dose MuCV can effectively reduce the number of total patients. Children in schools are the key to reduce the mumps.

Abstract
Nasopharyngeal swabs were collected from patients through the influenza surveillance network of the CDC of Guangdong. All specimens between 2009 and 2014 were checked for influenza virus using MDCK cells and further subtyped. Of those collected, 542 H1N1pdm09, 230 A(H3N2)and 448 B viruses selected at random were subjected to fluorescence-based NAI assays. Viral RNA was extracted from resistant isolates, and their NA genes were amplified by RT-PCR. Alignment of nucleotides and amino acids was performed. We performed structural modelling and simulations of mutants using Modeller 9.x and AutoDock and analyzed conformations and binding affinities. All tested seasonal type B and H3N2 viruses from 2009 to 2014 remained sensitive to oseltamivir. However, there were five strains (out of 198 tested isolates acquired between June and September 2013) that were resistant to oseltamivir. Another three resistant strains were identified among isolates from March to April 2014. We found that 2013/2014 oseltamivir-resistant strains and 2012/2013/2014 oseltamivir-sensitive strains had all or some of the following mutations: N44S, N200S,V241I, I321V,N369K, N386 K and K432E. MutationsV241I, N369K, N386K and K432E, alone or in conjunction with H275Y, had a significant impact on the binding pattern and affinity of oseltamivir for neuraminidase, rendering neuraminidase less susceptible.

Abstract
Expression of bromodomain protein 4 (BRD4) has been reported to predict a worse prognosis in solid tumors. However, its expression profile and prognostic value in gastric carcinoma (GC) remains unknown. Here we investigated BRD4 expression in GC and explored its association with patient survival. Tissue samples were obtained from 95 GC patients who underwent surgical resection to remove the primary tumor from January 2009 to December 2010. Immunohistochemistry was used to detect the expression of BRD4 in GC tissues and adjacent normal tissues. Kaplan-Meier survival curves and Cox proportional hazards regression were used to analyze the data of BRD4 expression profile and clinicopathological characteristics. Immunohistochemical analysis revealed BRD4 was overexpressed in GC tissue compared with adjacent normal tissue. BRD4 expression was significantly associated with TNM stage (p < 0.001), lymphatic permeation (p = 0.011), and vital status at the end of follow-up (p < 0.001). Kaplan-Meier survival curves and the log-rank test demonstrated that higher BRD4 expression was an adverse predictive factor for survival in GC. Multivariate analysis by Cox proportional hazards regression revealed that BRD4 expression was an independent worse prognostic factor in GC. In conclusion, BRD4 could act as a potential biomarker for prognostic assessment of GC.

Abstract
BACKGROUND Ulinastatin or urinary trypsin inhibitor (UTI) has been shown to ameliorate the inflammatory response induced by experimental severe acute pancreatitis (SAP) and hence reduce the mortality, however the mechanism of its action remains incompletely understood. We have investigated the effect of ulinastatin on regulatory T-cells (Tregs) in an established rat model of SAP. METHODS We established a rat SAP model by injecting 5% Na-taurocholate into the pancreatic duct and treated the SAP rats with ulinastatin with different dose level (5000, 10000, 30000 U/kg) through intraperitoneal injection at 0, 6 and 12 h. RESULTS We showed that the tissue damage of pancreas and the mortality of the SAP rats were significantly reduced by ulinastatin. We also showed that in the SAP rats the frequencies of CD4+ T cells and Tregs, as well as the expressions of TGF-β1, CTLA-4, and Foxp3 were decreased in the SAP animals while IL-1β, IL-10 and TNF-α were significantly increased. Treatment with ulinastatin up-regulated the proportion of Tregs in CD4+ T cells and the expression of IL-10, Foxp3 and CTLA-4 in the SAP rats in a dose dependence fashion, while down-regulating the levels of L-1β and TNF-α, myeloperoxidase (MPO) activity. CONCLUSIONS Our findings suggest that ulinastatin alleviates inflammatory response and tissue damage in SAP rats by increasing the proportion of Tregs. Our study provides a new mechanism for the beneficial effect of ulinastatin in SAP rat model.

Abstract
Objective: To explore the effects of X-ray repair cross complementing gene 1 (XRCC1) polymorphism and low dose ionizing radiation exposure on radiology professionals' peripheral blood lymphocyte micronucleus. Methods: A matched case-control study was designed. From 2013 to 2015, 1 102 radiology professionals with micronucleus test rusults, and 45 cases with present micronucleus were enroled into case group. 180 diagnostic radiology technicians detecting no micronucleus were chosen as control group, cases and controls were 1∶4 mached on gender, age ≤40 or >40 years old. According to the detection of micronucleus levels (0‰, 1‰, 2‰) , the objects of our study were divided into the reference group, the low detection group and the medium detection group. The form of radiation workers' occupational health examination was used to collect the general baseline of the research objects, history of smoking, drinking, poisonous and harmful material exposure, past medical history, accumulated illuminated dose and lymphocyte micronucleus rates (‰) , etc. Using restriction fragment length polymorphism polymerase chain reaction (RFLP-PCR) technology for genotyping; Compared the baseline data and radiation exposure level between the differentmicrokernel detection groups; Adopted multivariate logistic regression to analysis the combination effect of XRCC1 Arg399Gln gene polymorphism and accumulated illuminated dosefor micronucleus rate. Results: The accumulated illuminated dose in the reference group, the low detection group and the medium detection group were (23.44±15.23) , (21.76±2.56) , (24.22±18.61) mSv, respectively. There was no statistically significant difference among the groups (P>0.05) . Under the dominant inheritance mode, after adjusted age, smoking and drinking factors, the results suggested that XRCC1 Arg399Gln micronucleus medium detection group compared with the reference group, Arg399Gln-GG as reference, Arg399Gln-GA+AA decreased the occurrence of micronucleus (OR=0.175, 95%CI: 0.036-0.848) . Arg194Trp and Arg280His did not affect the incidence of micronucleus (P>0.05) . Did not find the combination effect of XRCC1 Arg399Gln gene polymorphism and accumulated illuminated dose for micronucleus rate (P>0.05) . Conclusion:XRCC1 Arg399Gln gene polymorphism can affect the incidence of micronucleus, and carrying the XRCC1 Arg399Gln-GA+AA genotype is a protective factor of micronucleus's occurrence, but low dose ionizing radiation may not affect the occurrence of micronucleus independently.

Abstract
OBJECTIVES To assess the usefulness of contrast-enhanced ultrasound (CEUS) with peritumoral injection of microbubble contrast agent for detecting the sentinel lymph nodes for oral tongue carcinoma. METHODS The study was carried out on 12 patients with T1-2cN0 oral tongue cancer. A radical resection of the primary disease was planned; a modified radical supraomohyoid neck dissection was reserved for patients with larger lesions (T2, n = 8). The treatment plan and execution were not influenced by sentinel node mapping outcome. The Sonovue™ contrast agent (Bracco Imaging, Milan, Italy) was utilized. After detection, the position and radiologic features of the sentinel nodes were recorded. RESULTS The identification rate of the sentinel nodes was 91.7%; one patient failed to demonstrate any enhanced areas. A total of 15 sentinel nodes were found in the rest of the 11 cases, with a mean of 1.4 nodes for each patient. The sentinel nodes were localized in: Level IA-1 (6.7%) node; Level IB-11 (73.3%) nodes; Level IIA-3 (20.0%) nodes. No contrast-related adverse effects were observed. CONCLUSIONS For oral tongue tumours, CEUS is a feasible and potentially widely available approach of sentinel node mapping. Further clinical research is required to establish the position of CEUS detection of the sentinel nodes in oral cavity cancers.

Abstract
NK cells participate in the development of human multiple sclerosis (MS) and mouse experimental autoimmune encephalomyelitis (EAE), but the roles of different NK cell subsets in disease onset remain poorly understood. In this study, murine NK cells were divided into CD27high and CD27low/− subsets. The CD27high subset was decreased and the CD27low/− subset was increased in lymphoid organs during the pre-onset stage of EAE. Compared with the counterpart in naïve mice, the CD27high subset showed lower expression of Ly49D, Ly49H and NKG2D, and less production of IFN-γ, whereas the CD27low/− subset showed similar expression of the above mentioned surface receptors but higher cytotoxic activity in EAE mice. Compared with the CD27high subset, the CD27low/− subset exhibited increased promotion of DC maturation and no significant inhibition of T cells proliferation and Th17 cells differentiation in vitro. Additionally, adoptive transfer of the CD27low/− subset, but not the CD27high subset, exacerbated the severity of EAE. Collectively, our data suggest the CD27 NK cell subsets play different roles in controlling EAE onset, which provide a new understanding for the regulation of NK cell subsets in early autoimmune disease.

Abstract
A large number of recipients are in a compromised immune defense condition because of the routine application of immunosuppressive regimens after heart transplantation. Our previous work demonstrated that blockade of high-mobility group box 1 (HMGB1) prolongs the graft survival. Whether and how HMGB1 blockade impacts respiratory responses against pathogen-like challenge in organ transplant recipients when it improves cardiac graft are not elucidated. At the present study, after abdominal heterotopic heart transplantation, the recipient mice were treated with HMGB1 mAb, and then challenged with poly(I:C) or LPS intratracheally on day 7 post transplantation. We found that the level of bronchoalveolar lavage (BAL) HMGB1 was elevated after heart transplantation, and aggravated responses to respiratory tract poly(I:C)/LPS challenge were observed. HMGB1 neutralizing mAb treatment in poly(I:C)-challenged recipient mice alleviated pulmonary histopathological changes, neutrophil infiltration and inflammatory cytokine release, but unaffected the level of IFN-β, the distribution of CD11b(+)CD27(+)/CD11b(+)CD27(-) NK cell subsets, and CD8(+) T cell responses. In LPS-exposed recipient mice, HMGB1 mAb treatment ameliorated pulmonary inflammatory damage and enhanced the phagocytosis of phagocytic cells. Thus, this study may establish a basis for the application of HMGB1 blockade to improve the outcomes of heart transplant recipients because HMGB1 inhibition ameliorates pulmonary inflammation, but maintains defense-associated responses.

Abstract
Mutagen sensitivity assay, which measures the enhanced cellular response to DNA damage induced in vitro by mutagens/carcinogens, has been used in the study of cancer susceptibility. 4-Nitroquinoline-1-oxide (4-NQO), an ultraviolet (UV) radiation-mimetic chemical, can produce chromosomal breaks in mammalian cells and induce cancer. Given the potential role of 4-NQO as the experimental mutagen substituting for UV as the etiological carcinogen of cutaneous melanoma (CM), we tested the hypothesis that cellular sensitivity to 4-NQO is associated with the risk of developing CM in a case-control study of 133 patients with primary CM and 176 cancer-free controls. Short-term blood cultures were treated with 4-NQO at a final concentration of 10 μmol/l for 24 h and scored chromatid breaks in 50 well-spread metaphases. Multivariate logistic regression was used to calculate odds ratios and 95% confidence intervals. We found that the log-transformed frequency of chromatid breaks was significantly higher in 133 patients than in 176 controls (P=0.004) and was associated with an increased risk for CM (adjusted odds ratio=1.78, 95% confidence interval: 1.12-2.84) after adjustment for age and sex. Moreover, as the chromatid break values increased, the risk for CM increased in a dose-dependent manner (P(trend)=0.003). Further analysis explored a multiplicative interaction between the sensitivity to 4-NQO and a family history of skin cancer (P(interaction)=0.004) on the risk of CM. Therefore, our findings suggest that sensitivity to 4-NQO may be a risk factor for the risk of CM, which is more sensitive than UV-induced chromotid breaks.

Abstract
The orbital two-channel Kondo effect displaying exotic non-Fermi liquid behaviour arises in the intricate scenario of two conduction electrons compensating a pseudo-spin-1/2 impurity of two-level system. Despite extensive efforts for several decades, no material system has been clearly identified to exhibit all three transport regimes characteristic of the two-channel Kondo effect in the same sample, leaving the interpretation of the experimental results a subject of debate. Here we present a transport study suggestive of a robust orbital two-channel Kondo effect in epitaxial ferromagnetic L10-MnAl films, as evidenced by a magnetic field-independent resistivity upturn with a clear transition from logarithmic- to square-root temperature dependence and deviation from it in three distinct temperature regimes. Our results also provide an experimental indication of the presence of two-channel Kondo physics in a ferromagnet, pointing to considerable robustness of the orbital two-channel Kondo effect even in the presence of spin polarization of the conduction electrons. In metals, electronic scattering from defects by the two-channel Kondo effect is expected to cause deviation from standard low temperature behaviour, however this effect has not been unambiguously shown. Here, the authors present evidence consistent with all transport signatures of the effect in ferromagnetic L10-MnAl films.

Abstract
PURPOSE To establish optimum conditions for anti-tumour therapy, we evaluated the efficacy of doxorubicin using liposomal doxorubicin and local hyperthermia to improve the anti-tumour efficacy over liposomal doxorubicin alone in rabbit VX2 tumours. MATERIALS AND METHODS A VX2 tumour model was established in New Zealand white rabbits, which were randomly divided into five groups: 1) control, 2) free doxorubicin hydrochloride (Dox), 3) liposomal doxorubicin hydrochloride (L-Dox), 4) L-Dox plus 41 °C thermotherapy (L-Dox + 41 °C TT); and 5) L-Dox plus 43 °C thermotherapy (L-Dox + 43 °C TT). To achieve complete tumour remission, multiple high-dose administrations (5 mg/kg, once per week for a total of 3 weeks) were given. An ultrasound hyperthermia instrument was used to induce local hyperthermia and the systemic toxicity of Dox was evaluated by changes in weight, blood count and serum lactic dehydrogenase. The anti-tumour effect of Dox was evaluated by observing the gross tumour volume, weight and rabbit survival. RESULTS The white blood cell count following administration of Dox or L-Dox was lower than for control animals and those treated with L-Dox + 41 °C TT. There was no difference between the groups with regard to the red blood cell count. Compared with the control and Dox groups, tumour proliferation was significantly inhibited following administration of L-Dox, L-Dox + 41 °C TT and L-Dox + 43 °C TT, as evidenced by the difference in tumour volume, weight and survival time. Differences in tumour proliferation were also found between the L-Dox and thermotherapy groups. CONCLUSION Local hyperthermia combined with L-Dox can significantly improve anti-tumour efficacy and reduce systemic toxicity.

Coxsackievirus A21 (CV-A21) is a rarely detected serotype belonging to the species Enterovirus C (EV-C). In this study, we report the isolation and genetic characterization of CV-A21 in Shandong Province, China, during 1997 to 2013. A total of 13 strains were obtained from surveillance of cases of acute flaccid paralysis (AFP) (n = 9) and from environmental sewage (n = 4). Sequence comparison of the VP1 genes revealed high nucleotide sequence similarity (94.1 % to 99.8 % identity) among these Shandong strains during the period of 17 years and 75.8 % to 98.5 % sequence identity to foreign strains. Bayesian phylodynamic evolutionary analysis of Shandong and global CV-A21 VP1 sequences revealed that the inferred CV-A21 ancestral sequence dated back to 1750 (1643-1841) and evolved with 2.943 × 10(-3) substitutions per site per year. Alignment of the deduced VP1 amino acid sequences revealed changes that might alter the hydropathicity of the encoded protein. The complete genome of one strain from 2013 was sequenced and evidence of recombination was detected by similarity plot and bootscanning analyses. This study describes the complete genome characterization and molecular epidemiology of CV-A21 in China and gives further insight into CV-A21 evolution.

Abstract
To analyze the genetic characteristics of a polio-I highly variant vaccine recombinant virus in Shandong Province (China) in 2011 and to identify isolates from healthy contacts, two stool specimens from one patient with acute flaccid paralysis (AFP) and 40 stool specimens from his contacts were collected for virus isolation. The complete genome of poliovirus and VP1 coding region of the non-polio enterovirus were sequenced. Homologous comparison and phylogenetic analyses based on VP1 sequences were undertaken among coxsackievirus (CV) B1, CV-B3 isolates, and those in GenBank. One poliovirus (P1/11186), CV-A4 and CV-A8 were isolated from the AFP patient; one CV-A2, Echovirus 3 (E-3), E-12 and E-14, ten CV-B1, and five CV-B3 strains were isolated from his contacts. These results led us to believe that there may be a human enterovirus epidemic in this area, and that surveillance must be enhanced. P1/11186 was a type-1 vaccine-related poliovirus; it combined with type-2 and type-3 polioviruses in 2A and 3A regions, respectively. There were 25 nucleotide mutations with 9 amino-acid alterations in the entire genome. There were 8 nucleotide mutations with 5 amino-acid alterations in the VP1 region compared with the corresponding Sabin strains. Homology analyses suggested that the ten CV-B1 isolates had 97.0%-100% nucleotide and 98.9%-100% amino-acid identities with each other, as well as 92.6%-100% nucleotide and 99.2%-100% amino-acid identities among the five CV-B3 isolates. Phylogenetic analyses on the complete sequences of VP1 among CV-B1 and CV-B3 isolates showed that Shandong strains, together with strains from other provinces in China, had a close relationship and belonged to the same group.

Abstract
OBJECTIVE To study the inhibitory activities of 3-O-β-chacotriosyl benzyl ursolate and its derivatives as potential new anti-influenza virus agents against the entry of H5N1 influenza viruses into the target cells. METHODS Four target compounds were designed and synthesized, which were structurally related to the lead compound 3-O-β-chacotriosyl methyl ursolate (1). The inhibitory activities of these compounds were tested at a cellular level psuedovirus system targeting H5N1 influenza viruse entry. RESULTS AND CONCLUSION The compounds 1b, 1c and 1d showed potent inhibitory activities against the entry of A/Thailand/Kan353/2004 pseudovirus into the target cells, and among them compound 1d showed the strongest inhibitory activity with an IC50 value of 0.96 ± 0.10 µmol/L. The structure-activity relationship analysis of these compounds indicated that when 17-COOH of ursolic acid was esterified, introduction of Me groups rather than aryl groups more strongly enhanced the inhibitory activity. Changing 17-COOH of ursolic acid into amide could increase the antiviral activity and decrease the cytotoxicity of the compounds in MDCK cells.

Abstract
High mobility group box 1 (HMGB1), a nonhistone chromatin associated protein, plays different roles according to the expression pattern such as the amount, cell location and sub-cellular location. It has been recently demonstrated that the systemic HMGB1 is associated with autoimmune encephalomyelitis. However, the dynamic change of HMGB1 expression pattern in spinal cords that may be involved in the progression of disease is not fully understood. In this study, the amount, cell location and subcellular location of HMGB1 in adult mice spinal cords during various stages of experimental autoimmune encephalomyelitis (EAE) are investigated. HMGB1 is expressed in the nuclei of spinal cord resident cells such as some astrocytes, microglia and a few neurons in normal situation. During EAE progression, the total and extracellular HMGB1 in the spinal cord are increased, more HMGB1 positive astrocytes and microglia are observed, and the intra-neurons HMGB1 in the ventral horn and around the central canal localize majorly in the cytoplasm accompanied by the increasing extracellular HMGB1. Blockade of HMGB1 in central nervous system (CNS) locally attenuates the severity of EAE significantly. Our findings indicate that the HMGB1 expression pattern in the spinal cord is associated with the progression of EAE. HMGB1 may be a potential target for autoimmune encephalomyelitis (multiple sclerosis in human) therapy.

Abstract
OBJECTIVE To compare ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI) for clinical differential diagnosis in patients with salivary gland tumor (SGT). STUDY DESIGN Six databases were used to search the literature published between 1982 and 2013. Histologic diagnosis was required as standard diagnosis. Pooled estimate for sensitivity, specificity, summary receiver-operating characteristic curve (SROC) and area under curve (AUC) were calculated and compared using STATA and Meta-Disc statistical software. RESULTS Nineteen articles were included. Pooled sensitivity for US, CT, and MRI was 0.629 (95% confidence interval [CI] 0.52-0.73), 0.830 (95% CI 0.74-0.90), and 0.807 (95% CI 0.73-0.87), respectively; pooled specificity for US, CT, and MRI was 0.920 (95% CI 0.89-0.94), 0.851 (95% CI 0.79-0.90), and 0.886 (95% CI 0.85-0.92), respectively. The AUC under SROC for US, CT, and MRI was 0.934 ± 0.058, 0.912 ± 0.889, and 0.903 ± 0.045, respectively. CONCLUSIONS CT is recommended, as it is an effective imaging tool for differential diagnosis in patients with primary SGT, and MRI is suggested for differential diagnosis between benign and malignant GSTs because of its highest sensitivity and specificity.

Abstract
The last case of infection with wild-type poliovirus indigenous to China was reported in 1994. In 2011, a poliomyelitis outbreak caused by imported wide-type poliovirus occurred in Xinjiang Uighur Autonomous Region. Here, we report the results of enterovirus (EV) isolation from Xinjiang students that returned to school in Shandong after summer vacation during this outbreak. Stool specimens from 376 students were collected and 10 EV strains were isolated including 4 polioviruses (All Sabin strains), 1 coxsackievirus (CV) A13, 3 CVA17 and 2 EV-C99. VP1 sequence analysis revealed these CVA13, CVA17 and EV-C99 strains had 71.3–81.8%, 76.5–84.6% and 74.2–82.9% nucleotide similarity with strains from other countries within a serotype, respectively. EV-C99 strains had 82.7–92.8% VP1 similarity with two previously reported Xinjiang strains. Complete genome analysis on EV-C99 strains revealed intra-serotypic genetic recombination events. These findings reflect great genetic divergence between Chinese strains and strains from other countries of the three types, and provide valuable information on monitoring EV transmission over long distance.

Abstract
Coxsackievirus B3 (CVB3) is an important human pathogen, which is frequently associated with aseptic meningitis and encephalitis in many parts of the world. However, the seroprevalence of this viral infection in China is not well understood; therefore, in the present study, we conducted a serological survey in which 373 serum samples obtained from healthy people belonging to 10 age groups in Yantai city, China were examined. The results revealed that CVB3 is widely distributed in the population with a seroprevalence of 52.3%. The seroprevalence of CVB3 was lowest (3.7%) in the group aged 8-12 months and >50% in all groups aged >15 years. A significant increase (P < 0.001) was observed among the successive four groups aged 1, 2-4, 5-7, and 8-10 years. Variation of geometric mean titer related to age showed similar tendencies. Our results indicated that CVB3 infections occurred mostly in preschool and early-elementary school settings, and children <5 years of age are the most susceptible populations due to their low CVB3 antibody levels.

Abstract
Chronic rejection that leads to diffuse narrowing and occlusion of graft vessels is the most important cause of morbidity and mortality following cardiac transplantation. The role and underlying mechanism of high-mobility group box 1 (HMGB1), as an established inflammatory mediator in acute rejection, remains poorly understood in chronic rejection. Here, we assessed the effects and mechanisms of HMGB1 on the chronic rejection using single MHC Class II-mismatched mouse cardiac transplantation model. It was found that HMGB1 was increased accompanying with the development of chronic rejection, while blockade of HMGB1 with specific neutralizing mAb substantially ameliorated chronic rejection-mediated vasculopathy and fibrosis of allograft, as well as markedly decreased T cell infiltration and production of IL-17A and interferon-gamma in allograft and recipient's spleen. Further, anti-HMGB1 antibody treatment significantly declined the number and frequency of mature dendritic cells (DCs) in allograft and recipient's spleen, especially CD11b(+) Ly6C(high) matured DCs that share the phenotypes with inflammatory-DCs. These findings indicate that HMGB1 contributes to chronic rejection, and HMGB1 blockade may be a novel mean to disrupt the proinflammatory loop after heart transplantation.

Abstract
Collagenases are widely used for tissue digestion in experiments due to their potent hydrolysis of connective tissue. CD27, also known as tumor necrosis factor receptor superfamily 7 (TNFRSF7), is limited to be expressed on the cells of the lymphoid lineage. In our preliminary research, we found that CD27 on NK cells was almost disappeared with the digestion of type I collagenase for 90min. This phenomenon suggests that the process of tissue digestion may affect the density of CD27 on cells. In order to verify this, the lungs of mice were digested with types I and IV collagenase or grinded, respectively. The percentage of CD27(+) cells and the density of CD27 on cells were assayed by flow cytometry. The data presented that the percentage of CD27(+) cells and the density of CD27 on lymphocytes gradually decreased with the time of digestion with type I or IV collagenase. We also detected that the density of CD11b on NK cells was not affected by collagenase digestion. Collectively, the findings of the present study suggest that the collagenase digestion has a selective effect on the density of molecules on cells.

Abstract
OBJECTIVE The aim of this study was to characterize the ultrasound (US) and computed tomography (CT) findings of primary acinic cell carcinoma (AciCC) of the parotid gland. SUBJECTS AND METHODS Seventy patients (70 lesions) with histopathologically proven AciCC underwent US or CT examination. The following characteristics were assessed on US images: size, shape, border, echogenicity, echotexture, internal structure, distal acoustic enhancement, and vascularity. The following characteristics were evaluated on CT images: size, shape, border, density, CT values on plain and contrast-enhanced scans, enhancement pattern, enhancement degree, and surrounding bone destruction. RESULTS On US images, lesions were irregular, well-defined, hypoechoic, heterogeneous, and poorly vascularized. On CT images, lesions were regular and well-defined, and showed slight heterogeneous enhancement. CONCLUSION These findings suggest that most primary AciCCs show benign features on US and CT.

Abstract
Environmental surveillance of poliovirus on sewage has been conducted in Shandong Province, China since 2008. A type 2 vaccine-derived poliovirus (VDPV) with 7 mutations in VP1 coding region was isolated from the sewage collected in the city of Jinan in December 2012. The complete genome sequencing analysis of this isolate revealed 25 nucleotide substitutions, 7 of which resulted in amino acid alteration. No evidence of recombination with other poliovirus serotypes was observed. The virus did not lose temperature sensitive phenotype at 40°C. An estimation based on the evolution rate of the P1 coding region suggested that evolution time of this strain might be 160–176 days. VP1 sequence analysis revealed that this VDPV strain is of no close relationship with other local type 2 polioviruses (n = 66) from sewage collected between May 2012 and June 2013, suggesting the lack of its circulation in the local population. The person who excreted the virus was not known and no closely related virus was isolated in local population via acute flaccid paralysis surveillance. By far this is the first report of VDPV isolated from sewage in China, and these results underscore the value of environmental surveillance in the polio surveillance system even in countries with high rates of OPV coverage.

Abstract
Even to date, Oral squamous cell carcinoma (OSCC), which is one of the most common malignancies worldwide, is still a major public health problem. The cellular mechanisms underlying development of OSCC are poorly understood. Lipid rafts-associated proteins not only serve as a docking platform for protein sorting and membrane trafficking, but also coordinate signaling molecules at cell membrane to mediate intracellular responses, which makes them susceptible to be subverted by cancer cells. Although Flotillin-1 has been discovered for decades, its potential role in OSCC development is largely unknown. In current study, we demonstrate that Flotillin-1 is highly expressed in OSCC cell lines compared to normal oral epithelial cells. Modulation of Flotillin-1 expression via transfection with Flotillin-1 expression vector or shRNA showed that Flotillin-1 has a clearly positive impact on cell growth and motility in KB and/or Tca8113 cell lines. These observations were further supported by using mice or zebrafish tumor xenograft models. Mechanistic study indicated that Flotillin-1 expression activates NF-κB signaling pathway by enhancing phosphorylation of p65 and IκBα, and translocation of p65 into nucleus. Furthermore, inhibition of EGFR by AG1478 markedly repressed Flotillin-1-induced activation of NF-κB signaling pathway. Our studies suggested that Flotillin-1 plays an important role in OSCC development, and might be a potential therapeutic target for OSCC.

Abstract
OBJECTIVE The objective of this study was to investigate the ability of sonography for diagnosis of mucoepidermoid carcinoma (MEC) in the salivary glands. STUDY DESIGN Sonographic images of 74 cases were analyzed retrospectively; the features evaluated included size, echogenicity, shape, internal structure, distal acoustic enhancement, and regional lymph node enlargement and vascularization, and categorized them into 3 groups based on histology (low, intermediate, and high grade). RESULTS The lesion size of low-grade MEC was smaller than those of intermediate- and high-grade MEC. MEC lesions of the salivary glands were mostly associated with heterogeneous echotexture, indistinct margins, irregular shape, and absence of distal acoustic enhancement. They sometimes showed cystic areas, calcifications, regional lymph node enlargement, or were well vascularized on Doppler. There were no significant sonographic differences in low-, intermediate-, and high-grade MEC. CONCLUSIONS Salivary MEC presents a variety of sonographic appearances, which would aid in the diagnosis of salivary MEC.

Abstract
A novel horseradish peroxidase- (HPR-) doped magnetic core-shell Fe3O4@SiO2@Au nanocomposites (Fe-Au MNPs) were employed on immunoassay for the determination of C-reactive protein (CRP) based on a electrochemical quartz crystal microbalance detector (EQCM). Firstly, the secondary CRP antibody and HRP were both immobilized on the Fe-Au MNPs (Fe-Au MNPs-anti-CRP2/HRP) as a signal tag. Secondly, the above tag and the primary antibody (anti-CRP1) in the bottom of 96-well microtiter plate were employed to conjugate with a serial of CRP concentrations to produce a sandwich immunocomplex. Thirdly, the immunocomplex solution was subsequently exposed to 3, 3'-diaminobenzidine (DAB) in the presence of H2O2, resulting in an insoluble product. When the precipitation solution was dripped on EQCM, it can achieve a decrease of frequency of crystal (Δf). The amount of Δf was proportional to (CRP) from 0.003 to 200 ng mL(-1) with a low detection limit of 1 pg mL(-1). Compared with the enzyme-linked immunosorbent assay (ELISA), the immunoassay shows greatly improved sensitivity due to the significant amount of HRP labeled on signal tag. It also has good specificity and low sample consumption, which is expected to be a benefit for the CRP screening in early diagnosis of cardiovascular disease.

Abstract
BACKGROUND The remodeling patterns in different types of chronic rhinosinusitis (CRS) have rarely been compared, particularly the difference between eosinophilic and noneosinophilic CRS with nasal polyps (CRSwNP). Moreover, whether there is a link between remodeling and inflammation remains controversial. OBJECTIVE To directly compare the remodeling features of different CRS and to explore their relationship with inflammation in Chinese patients. METHODS Histologic characteristics of surgical samples were analyzed in 33 controls, 72 eosinophilic and 76 noneosinophilic CRSwNP, and 72 CRS without nasal polyps (CRSsNP) patients. Tissue samples from 38 controls, 26 eosinophilic and 26 noneosinophilic CRSwNP, and 32 CRSsNP patients were measured for mRNA and/or protein expression of profibrotic growth factors, metalloproteinases (MMPs), tissue inhibitor of metalloproteinases (TIMPs), hypoxia-inducible factor (HIF)-1α, interleukin (IL)-8, eosinophil cationic protein (ECP), and myeloperoxidase (MPO). RESULTS The amount of collagen decreased, whereas the edema scores increased, from CRSsNP to noneosinophilic CRSwNP and to eosinophilic CRSwNP. Transforming growth factor (TGF)-β2 protein levels were enhanced in CRSsNP compared with CRSwNP. TIMP-4 protein levels decreased in eosinophilic CRSwNP compared with noneosinophilic CRSwNP and CRSsNP. The number of neutrophils decreased from CRSsNP to noneosinophilic CRSwNP and to eosinophilic CRSwNP. ECP levels were only up-regulated in eosinophilic CRSwNP. ECP levels and neutrophil number correlated positively with the severity of edema and fibrosis, respectively. Neutrophils were the major sources of TGF-β2 in CRSsNP and noneosinophilic CRSwNP. CONCLUSION Distinct remodeling patterns are revealed for different types of CRS, particularly for eosinophilic and noneosinophilic CRSwNP. Tissue remodeling associates with inflammation in CRS.

Abstract
A novel strategy is presented for sensitive detection of alfa-fetoprotein (AFP), using a horseradish peroxidase (HRP)-functionalized Envision antibody complex (EVC) as the label. The Envision-AFP signal antibody copolymer (EVC-AFP Ab2) was composed of a dextran amine skeleton anchoring more than 100 molecules of HRP and 15 molecules of secondary antibody, and acted as a signal tag in the immunosensor. The sensor was constructed using the following steps: First, gold electrode (GE) was modified with nano-gold (AuNPs) by electro-deposition in HAuCl4 solution. The high affinity of the AuNPs surface facilitates direct formation of a self-assembled thiolated protein G layer. Next, the coated GE was incubated in a solution of AFP capture antibody (AFP Ab1); these antibodies attach to the thiolated protein G layer through their non-antigenic regions, leaving the antigen binding sites for binding of target analyte. Following a sandwich immunoreaction, an EVC-AFP Ab2-AFP-AFP Ab1 immunocomplex was formed on the electrode surface, allowing large amounts of HRP on the complex to produce an amplified electrocatalytic current of hydroquinone (HQ) in the presence of hydrogen peroxide (H2O2). Highly amplified detection was achieved, with a detection limit of 2 pg/mL and a linear range of 0.005–0.2 ng/mL for AFP in 10 μL undiluted serum; this is near or below the normal levels of most cancer biomarker proteins in human serum. Measurements of AFP in the serum of cancer patients correlated strongly with standard enzyme-linked immunosorbent assays. These easily fabricated EVC-modified immunosensors show excellent promise for future fabrication of bioelectronic arrays. By varying the target biomolecules, this technique may be easily extended for use with other immunoassays, and thus represents a versatile design route.

Abstract
Background The rubella vaccine was introduced into the immunization program in 1995 in the Shandong province, China. A series of different rubella vaccination strategies were implemented at different stages of measles control in Shandong province. Methodology/Principal Findings The average reported incidence rate of rubella cases remained at a low level in Shandong province after 1999. However, rubella epidemics occurred repeatedly in 2001/2002, 2006, and 2008/2009. The age of the onset of rubella cases gradually increased during 1999–2010, which showed that most cases were found among the 10 years old in 1999 and among the 17 years old in 2010. Phylogenetic analysis was performed and a phylogenetic tree was constructed based on the World Health Organization standard sequence window for rubella virus isolates. All rubella viruses isolated in Shandong province were divided into 4 genotypes: 1E, 1F, 2A, and 2B. Genotype 1E viruses accounted for the majority (79%) of all these viruses. The similarity of nucleotide and amino acid sequences among genotype 1E viruses was 98.2–100% and 99.1–100%, respectively. All Shandong genotype 1E strains, differed from international genotype 1E strains, belonged to cluster 1 and interdigitated with the viruses from other provinces in mainland China. The effective number of infections indicated by a Bayesian skyline plot remained constant from 2001 to 2009. Conclusions/Significance The gradual shift of disease burden to an older age group occurred after a rubella-containing vaccine was introduced into the childhood immunization schedule in 1995 in Shandong province. Four genotypes, including 1E, 1F, 2A, and 2B, were found in Shandong province during 2000–2009. Genotype 1E, rather than genotype 1F, became the predominant genotype circulating in Shandong province from 2001. All Shandong genotype 1E viruses belong to the genotype 1E/cluster 1; they have constantly circulated, and co-evolved and co-circulated, with those from other provinces.

Abstract
Oral squamous cell carcinoma (OSCC) accounts for about 90% of malignant oral lesions, and is recognized as the third most common cancer in developing nations and the sixth most common cancer worldwide. While chemotherapy remains the primary treatment for both resectable and advanced OSCC, most OSCC are naturally resistant to anticancer drugs, rendering new therapeutic avenues in dire need. Sirt1, a class III histone deacetylase, was linked to cisplatin resistance in several cancer types; however, the underlying mechanism is still unclear. Here, we demonstrated that overexpression of Sirt1 survived OSCC cell line Tca8113 under cisplatin treatment. Notably, BML-210, a chemical inhibitor of class III histone deacetylase, significantly abolished Sirt1-mediated cisplatin resistance in Tca8113 cells. Further, inactivation of endogenic Sirt1 by nicotinamide markedly increased chemo-sensitivity in cisplatin resistant sub-cell line Tca8113/CDDP. Proteomic strategy was applied to profile the differentially expressed proteins between pcDNA3.1-Sirt1- and mock vector-treated Tca8113 cells. Among 54 spots identified, 31 proteins were up-regulated and 23 proteins were down-regulated upon Sirt1 expression. Expression of four proteins with most significant alteration, including Annexin A4, Stathmin, SOD2 and thioredoxin, were validated by both RT-PCR and Western blot. Finally, we showed that Sirt1 could prevent cisplatin-induced ROS accumulation in Tca8113 cells. Our findings are considered as a significant step toward a better understanding of Sirt1-mediated cisplatin resistance.

Abstract
Hypersensitivity to radiation exposure has been suggested to be a risk factor for the development of breast cancer. In this case-control study of 515 young women (≤ 55 years) with newly diagnosed sporadic breast cancer and 402 cancer-free controls, we examined the radiosensitivity as measured by the frequency of chromatid breaks induced by gamma-radiation exposure in the G2 phase of phytohemagglutinin-stimulated and short-term cultured fresh lymphocytes. We found that the average chromatid breaks per cell from 50 well-spread metaphases were statistically significantly higher in 403 non-Hispanic White breast cancer patients (0.52 ± 0.22) than that in 281 non-Hispanic White controls (0.44 ± 0.16) (P value < 0.001), and in 60 Mexican American breast cancer patients (0.52 ± 0.19) than that in 65 Mexican American controls (0.44 ± 0.16) (P value = 0.021), but the difference was not significant in African Americans (52 cases [0.45 ± 0.16] versus 56 controls [0.47 ± 0.16], P = 0.651). The frequency of chromatid breaks per cell above the median of control subjects was associated with two-fold increased risk for breast cancer in non-Hispanic Whites and Mexican Americans. A dose-response relationship was evident between radiosensitivity and risk for breast cancer (P (trend) < 0.001) in these two ethnic groups. We concluded that gamma-ray-induced mutagen sensitivity may play a role in susceptibility to breast cancer in young non-Hispanic White and Mexican American women.

Abstract
The prognostic significance of ultrasound real-time elastography (RTE) in patients with breast lesions is controversial. There are two different diagnostic methods: the elasticity score (ES) and the strain ratio (SR). A meta-analysis was performed using a random-effect model to assess the overall sensitivity and specificity of RTE in the differentiation of breast lesions. MEDLINE, EMBASE, PubMed, and the Cochrane Library before February 2011 were searched. A total of 22 studies, which included 4,713 breast nodules in 4,266 patients were analyzed. The overall mean sensitivity and specificity for the diagnosis of malignant breast lesions by RTE were 0.834 [95% confidence interval (CI) 0.814-0.853] and 0.842 (95% CI, 0.829-0.854) for ES, and 0.883 (95% CI, 0.844-0.916) and 0.814 (95% CI, 0.786-0.839) for SR, respectively. RTE has a high sensitivity and specificity in the evaluation of breast lesions and can potentially reduce unnecessary breast biopsies.
