Abstract
OBJECTIVE To compare the preliminary clinical outcomes of fenestration discectomy associated with annulus repair (FDAR) and fenestration discectomy (FD) for lumbar disc herniation in the adolescents. METHODS The data of 26 adolescent patients with single segment lumbar disc herniation who were admitted to the Department of Orthopedics, Xuzhou Central Hospital from October 2012 to October 2014 were retrospectively studied. All patients were divided into 2 groups, including 12 patients undergoing FDAR and 14 patients undergoing FD respectively. The factors including the length of skin incision, amount of intraoperative bleeding, operation time and duration of hospitalization were compared. The indentation of dura were measured from MRI. Pfirrmann grading system was used for assessment of lumbar disc degeneration preoperatively and 1 year later. The visual analogue scale (VAS), the oswestry disability index (ODI) and Japanese Orthopedic Association (JOA) scores were used to measure the clinical outcomes. Simultaneously, surgical complications, and postoperative recurrence of lumbar disc herniation were recorded. RESULTS There were no significant differences in the observational factors such as the skin incision length, amount of intraoperative bleeding, operation time, and duration of hospitalization between the FDAR and FD groups (P>0.05). The indentation of the dura significantly reduced after surgery in each group [FDAR: (7.3±2.6) vs (1.3±0.8) mm; FD: (7.4±3.1) vs (2.9±0.7) mm; both P<0.05]. The postoperative lumbar disc degeneration in FDAR group was the same as that of in FD group. The postoperative VAS scores and ODI scores at each follow-up time point in both groups were significantly improved when compared with the preoperative ones (P<0.05). There were no statistically significant differences between the 2 groups in the JOA score improvement rate (FDAR: 88.5%, FD: 87.2%; P>0.05). According to the modified MacNab criteria, there were no statistically significant differences between the 2 groups in the excellent and good rate (FDAR: 89.3%, FD: 88.5%; P>0.05). There were no dural tears, disc space infection, hematoma formation in the spinal canal and other serious complications in both groups. But there was one patient regaining the back and leg pain in the FD group, whereas recovering by conservative treatment. CONCLUSION The preliminary clinical efficacy of both FDAR and FD in the treatment of single segment lumbar disc herniation in the adolescents is satisfactory.

Abstract
OBJECTIVE To detect the spatial features of measles in China by means of spatial statistical analysis. METHODS Data of prefecture-level measles cases and incidence from 2005 to 2014 were collected from the China Information System for Disease Control and Prevention. Information collected from the system included demographic characteristics, spatial distribution information, and diagnostic reports. Cases of unconfirmed measles and those with unknown address were ruled out. Cases from Hong Kong, Macao, Taiwan, and foreign countries were not included in this study. Maps were obtained from geographical boundary data at prefecture level from the Chinese Center for Disease Control and Prevention and demographic data from the National Bureau of Statistics. Based on different measures of measles elimination, we divided the data from 2005 to 2014 into three stages: stage 1 (2005-2008), stage 2 (2009-2012), and stage 3 (2013-2014). ArcGIS software was used to describe the spatial distribution and for global and local spatial autocorrelation analysis. RESULTS The total number of confirmed measles cases reported in the system was 650 222, with average incidence 0.46/100 000. The highest reported incidence was in 2008 (9.95/100 000) and the lowest in 2012 (0.46/100 000). Average incidences for stages 1, 2, and 3 were 8.87/100 000, 1.99/100 000 and 2.96/100 000, respectively. Global Moran's I coefficients from 2005 to 2014 were 0.31, 0.08, 0.36, 0.56, 0.26, 0.48, 0.34, 0.20, 0.29 and 0.52, respectively; all were significant (P<0.05). Average incidences for high-high (H-H) clusters in 2005-2008, 2009-2012, and 2013-2014 were 33.02/100 000, 7.06/100 000, 11.91/100 000, respectively. Western China had high-value clustering consistently throughout all three periods; however, the number of prefectures covered by high-value clusters and discrepancy in the incidence between western and eastern regions were low. Northeast and northern China had H-H clustering in stages 2 and 3. CONCLUSION In this study, measles incidence was spatially autocorrelated at the prefecture level from 2005 to 2014. Although China has made great progress in the elimination of measles, H-H clusters were consistently present. A need remains in China for targeted measles prevention and control measures.

Abstract
Alloantibodies directed to red blood cell (RBC) antigens play an important role in alloimmune-mediated haemolytic transfusion reactions and haemolytic disease of the foetus and newborn. The frequencies and phenotypes of RBC antigens are different in populations from different geographic areas and races. However, the data on major blood group antigens in the Chinese Han population from Mainland China are still very limited; thus, we aimed to investigate them in this study. A total of 1412 unrelated voluntary Chinese Han blood donors were randomly recruited. All donors were typed for blood group antigens: D, C, c, E, e, C(w) , Jk(a) , Jk(b) ,M, N, S, s, Le(a) , Le(b) , K, k. Kp(a) , Kp(b) , Fy(a) , Fy(b) , Lu(a) , Lu(b) , P1 and Di(a) using serological technology. Calculations of antigen and phenotype frequencies were expressed as percentages and for allele frequencies under the standard assumption of Hardy-Weinberg equilibrium. Amongst the Rh antigens, D was the most common (98.94%) followed by e (92.28%), C (88.81%), c (58.43%), E (50.78%) and C(w) (0.07%) with DCe/DCe (R1 R1 , 40.72%) being the most common phenotype. In the Kell blood group system, k was present in 100% of the donors and a rare phenotype, Kp (a+b+), was found in 0.28% of the donors. For the Kidd and Duffy blood group systems, Jk (a+b+) and Fy (a+b-) were the most common phenotypes (44.05% and 84.35%, respectively). In the MNS blood group system, M+N+S-s+ (45.54%) was the most common, whereas M+N-S-s- and M-N+S-s- were not found. The rare Lu (a-b-) and Lu (a+b+) phenotypes were identified in 0.43% and 1.13% of the donors, respectively. Le(a) and Le(b) were seen in 17.92% and 63.03% of donors, respectively. The frequency of Di(a) was 4.75%, which was higher than in the Chinese population in Taiwan region or the Caucasian and Black populations (P < 0.0001). This study systematically describes the frequencies of 24 blood group antigens in the Chinese Han population from Mainland China. The data can be helpful in creating a donor database for preparation of indigenous cell panels and providing antigen-negative blood to patients with multiple alloantibodies.

Abstract
BACKGROUND Evidence demonstrates that the T allele of the single-nucleotide polymorphism rs405509 in the apolipoprotein E (APOE) promoter is a risk factor for Alzheimer's disease. However, it is unknown whether rs405509 T allele synergizes with the APOE ε4 allele in influencing cognition and brain structure. METHODS We analyzed the interaction effect of the rs405509 T allele and the APOE ε4 allele on cognitive ability and brain gray matter volume among elderly people. The subjects were grouped into four groups according to APOE and rs405509 genotypes. RESULTS Significant interaction effects were found between rs405509 and APOE on general mental status, memory and attention. Analysis of the whole brain gray matter showed a significantly positive interaction effect between rs405509and APOE on the right inferior temporal gyrus and right fusiform gyrus (alphasim correction P < 0.001). In addition, there was a significant relationship between cognitive ability and gray matter volume. CONCLUSIONS The data indicate that the APOE rs405509 T homozygote modulates the effect of APOE ε4 on both cognitive performance and brain gray matter structure.

Abstract
Data on the molecular epidemiology of Bordetella pertussis are limited in developing countries where whole-cell pertussis vaccines (WCVs) have been used. The aim of this study was to determine the genotypes of circulating B. pertussis in China by direct molecular typing of clinical specimens. DNA extracts of 122 nasopharyngeal swabs (NPs) positive for B. pertussis by polymerase chain reaction (PCR) (targeting IS481 and ptx-Pr) from 2012 to 2013 were used for typing using the multiple-locus variable number tandem repeat analysis (MLVA) and also by PCR-based multilocus sequence typing (MLST) of B. pertussis virulence genes (ptxP, prn, and fim3). One hundred and eight DNA extracts (89 %) generated a complete MLVA type (MT). Among the 18 MTs obtained, MT55 (52 %) and MT104 (13 %) were the most common. MT27, which is linked to the ptxP3 allele and is prevalent in many developed countries using acellular pertussis vaccines (ACVs), was only found in 7 (6 %) DNA extracts. Eighty-seven DNA extracts (71 %) produced a complete multiantigen sequence typing (MAST) type. Of them, 77 (89 %) had the ptxP1/prn1/fim3-1 allele profile. Four DNA extracts (5 %) had the ptxP3/prn2/fim3-2 profile and 3 (4 %) had the ptxP3/prn1/fim3-2 allele profile. These seven DNA extracts also harbored MT27. Our result shows that B. pertussis circulating in China was different from those found in countries where ACVs have been in use, supporting the notion that selection pressure induced by WCVs and ACVs on the bacterial population differs.

Abstract
UNLABELLED Many epidemiological studies have shown that in some tumors carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) and β-catenin appear to be related. However, it remains to be established whether CEACAM1 is related to β-catenin in osteoporosis. Here, we reveal that CEACAM1 might influence the canonical Wnt/β-catenin pathway to modulate bone metabolism in postmenopausal osteoporosis. INTRODUCTION The aim of this study is to assess the serum level of CEACAM1 in postmenopausal women and its correlation with β-catenin and bone mineral density (BMD). METHODS The BMD was measured at the lumbar spine (L1-L4) or the femoral neck using dual-energy X-ray absorptiometry (DXA). Serum CEACAM1, β-catenin, receptor activator of nuclear factor kappa-B (RANKL), osteoprotegerin (OPG), β-isomerized C-terminal crosslinking of type I collagen (β-CTX), intact N-terminal propeptide of type I collagen (PINP), estradiol, and insulin were measured in 350 postmenopausal women. Patients were divided according to lumbar spine or femur neck T-scores into osteoporosis (group I), osteopenia (group II), and normal bone mineral density, the latter serving as control. RESULTS Serum CEACAM1 levels were significantly lower in group I and II compared to those in control subjects (P < 0.001). Serum CEACAM1 levels correlated positively with β-catenin and BMD, but correlated negatively to the ratio between RANKL and OPG. CONCLUSION This study provides evidence that decreased serum CEACAM1 levels are related to low BMD in postmenopausal women, and that serum CEACAM1 levels correlated positively to β-catenin. It suggests that CEACAM1 might influence the canonical Wnt/β-catenin pathway to modulate bone metabolism.

Abstract
The aim of this study was to assess the performance of the blood pressure-to-height ratio (BPHR) for screening elevated blood pressure (BP) in children and adolescents using a meta-analysis of eligible published studies. We retrieved studies that investigated the performance of the BPHR for identifying elevated BP from Pubmed and other databases. We performed meta-analyses by subgroups of sex, age and ethnicity using a fixed or random effect model based on whether there was between-study heterogeneity. A total of 13 publications including 262 830 children and adolescents aged 6-18 years on BPHR and a total of three publications including 95 343 children on the modified BPHR were included in this meta-analysis. The summary results suggested that BPHR performed well to identify pre-high BP and high BP for children aged 6-11 years and adolescents aged 12-18 years. The performance of BPHR was perfect for identifying severe high BP in adolescents aged 12-18 years. However, the modified BPHR did not improve accuracy for screening high BP in children aged 6-12 years. In summary, BPHR performed well for identifying elevated BP in children and adolescents, independently of sex, age and ethnicity group. In addition, the modified BPHR performed similarly with BPHR for screening high BP in childhood.

Abstract
The annual flu season causes thousands of deaths and millions of hospitalizations, which pose a great burden to global health and economy. Moreover, a flu pandemic arising from reassortment viruses, such as H5N1 and H1N1, raises even greater concern due to the lack of effective vaccines at the initial stage of flu outbreak. The influenza virus is the causative agent of flu infection. Currently there are four drugs in use to combat influenza infection. Amantadine and rimantadine are M2 proton channel blockers that inhibit virus uncoating; oseltamivir and zanamivir are neuraminidase (NA) inhibitors that inhibit virus release. However, recent years have witnessed a drastic increase in instances of drug resistance, and flu strains that are resistant to both classes of drugs have been reported. Thus, there is a pressing need to develop the next generation of anti-influenza drugs. Among a handful of anti-influenza drug targets, the viral fusion protein hemagglutinin (HA) is one of the most advanced. This review discusses the biological roles of HA during viral replication and highlights peptide- and small molecule-based HA inhibitors, including recent computationally designed HA binders. The text is organized into four sections based on the maturation stages of HA: inhibitors targeting the glycosylation of HA, the proteolytic activation of HA, the attachment of HA to host cell receptors, and peptide- and small molecule-based inhibitors targeting HA-mediated membrane fusion. Of particular interest are advances in the areas of developing dual inhibitors targeting both HA and NA and broad-spectrum HA inhibitors targeting both groups of HAs.

Abstract
Abstract
Background: Approximately 20% of breast cancers are diagnosed in women 75 years of age or older. Elderly patients with breast cancer are at a higher risk for over- or under-treatment. In general, older patients are more likely to die from comorbidities than from their breast cancer. The 21-gene Recurrence Score (RS) predicts 10-year distant recurrence rate in the adjuvant setting in women with early stage ER+ breast cancer. In elderly patients, a large percentage of the cancers diagnosed are ER+. It is likely that a subpopulation of elderly women with good prognosis ER+ tumors can be identified who may benefit from endocrine therapy alone, without surgery, to treat their cancer without compromising clinical outcome. We hypothesize that endocrine therapy alone will provide adequate local and systemic control of breast cancer in the subpopulation of women 75 or older with ER+ breast cancer and low RS.
Trial Design: This is a single arm phase II trial in pts with newly diagnosed early stage ER+ breast cancer, age 75 or greater. RS will be obtained on core biopsies collected at the time of diagnosis. Patients whose scores are < 18 will be enrolled into the trial and receive endocrine therapy only. Patients whose scores are ≥ 18 will receive standard of care (SOC) treatment. Tumor assessment will occur every 6 months. Patient can continue on endocrine therapy for up to 10 years. If there is progression of disease, then an alternative endocrine agent may be prescribed or the patient can opt for SOC treatment.
Objectives: Primary: To determine the rate of loco-regional progression in women with early-stage ER+ breast cancer, 75 years or older with low RS who are treated with endocrine therapy alone. Secondary: To determine the breast cancer-specific survival and overall survival of women with early-stage ER+ breast cancer who are 75 years or older treated with endocrine therapy alone. To correlate response to treatment with RS.
Eligibility: Newly diagnosed invasive breast cancer defined as cT1 or T2, N0-1, M0, age 75 years of age or older and ECOG performance status ≤ 2. Disease must be ER+ (Allred score ≥ 5) and HER2- and measurable defined as lesions that can be accurately measured in at least one dimension by ultrasound or mammogram.
Statistical Methods: A Kaplan-Meier model will be used to estimate the 5-year local or systemic progression rate with a Brookmeyer-Crowley confidence interval. If the true 5-year progression rate is 10%, a sample size of 50 will provide power = .90 at a one-sided .05 significance level to demonstrate that the rate is less than 25.5%. A point estimate of the cumulative incidence of local progression at 5 years will be calculated using a Kaplan-Meier model or, if covariate adjustment is desired, a Cox proportional hazards model. The upper bound of a 95% confidence interval will be used to determine whether the rate may plausibly fall above 25.5%.
Accrual: Target 50 patients with an RS score < 18 will be enrolled. Anticipated opening is July 2015.

Abstract
Abstract
Background
Glycoprotein NMB (gpNMB) is an internalizable transmembrane protein overexpressed in approximately 20% of breast cancer (BC), including approximately 40% of TNBC. gpNMB is a poor prognostic marker in BC (Rose CCR 2010) and preclinically has been implicated in tumor invasion, metastasis, and angiogenesis. GV is a novel antibody-drug conjugate targeting the potent cytotoxin monomethylauristatin E (MMAE) to gpNMB overexpressing cancer cells.
In a Phase I/II study and the Phase II "EMERGE" study, GV demonstrated promising activity with TNBC patients (pts) deriving the greatest benefit and exhibiting the highest degree of gpNMB overexpression. GV was well-tolerated with the most frequent treatment-related toxicities consisting of rash, neutropenia, and neuropathy. In subset analyses of the EMERGE trial, objective response rate (ORR) was 30% (7/23) for GV vs. 9% (1/11) for investigator's choice in tumors with gpNMB overexpression (>25% of tumor epithelium); 18% (5/28) vs. 0% (0/11) in TNBC; and 40% (4/10) vs. 0% (0/6) in gpNMB-overexpressing TNBC for GV and IC respectively, with apparent improvements in progression-free survival (PFS; hazard ratio (HR) = 0.11) and overall survival (OS; HR = 0.14).
Trial design
The METRIC Trial (NCT#01997333) is an international (USA, CA, Aus), two-arm phase II study. Pts are randomized 2:1 to GV (1.88 mg/kg IV q 21 days) or capecitabine, a current standard of care for this population (2,500 mg/m2 daily for d1-14, q21 days) until progression or intolerance. Crossover is not permitted.
Eligibility criteria
Key eligibility criteria include: >25% of tumor epithelium gpNMB+ by central immunohistochemistry (IHC) screening of archival tissue; estrogen receptor and progesterone receptor <10% and HER2 negative [0-1+ IHC, or ISH copy number <4.0/ratio <2.0] by local assessment; ECOG 0-1; taxane resistance; anthracycline exposure (if indicated); <2 chemotherapy regimens for advanced BC; measurable disease; no persistent Grade >2 toxicity.
Specific aims
The primary endpoint is PFS per independent, blinded central review committee according to RECIST 1.1. Secondary endpoints are ORR, duration of response, OS, safety, pharmacokinetics and pharmacodynamics. Exploratory endpoints are quality of life and/or cancer-related pain.
Statistical methods and target accrual
The trial has 85% power to detect a PFS HR of 0.64 with two sided α = 0.05. The hypothesized median PFS is 4.0 months for capecitabine and 6.25 months for GV. Target accrual is open for 300 pts.
