Abstract
Y chromosomes display population variation within and between species. Co-evolution within populations is expected to produce adaptive interactions between Y chromosomes and the rest of the genome. One consequence is that Y chromosomes from disparate populations could disrupt harmonious interactions between co-evolved genetic elements and result in reduced male fertility, sterility or inviability. Here we address the contribution of 'heterospecific Y chromosomes' to fertility in hybrid males carrying a homozygous region of Drosophila mauritiana introgressed in the Drosophila simulans background. In order to detect Y chromosome-autosome interactions, which may go unnoticed in a single-species background of autosomes, we constructed hybrid genotypes involving three sister species: Drosophila simulans, D. mauritiana, and D. sechellia. These engineered strains varied due to: (i) species origin of the Y chromosome (D. simulans or D. sechellia); (ii) location of the introgressed D. mauritiana segment on the D. simulans third chromosome, and (iii) grandparental genomic background (three genotypes of D. simulans). We find complex interactions between the species origin of the Y chromosome, the identity of the D. mauritiana segment and the grandparental genetic background donating the chromosomes. Unexpectedly, the interaction of the Y chromosome and one segment of D. mauritiana drastically reduced fertility in the presence of Ysim, whereas the fertility is partially rescued by the Y chromosome of D. sechellia when it descends from a specific grandparental genotype. The restoration of fertility occurs in spite of an autosomal and X-linked genome that is mostly of D. simulans origin. These results illustrate the multifactorial basis of genetic interactions involving the Y chromosome. Our study supports the hypothesis that the Y chromosome can contribute significantly to the evolution of reproductive isolation and highlights the conditional manifestation of infertility in specific genotypic combinations.

Abstract
We experimentally investigate spectral control of high-harmonic generation in a wide-diameter (508 μm) capillary that allows using significantly lower gas pressures coupled with elevated drive laser energies to achieve higher harmonic energies. Using phase shaping to change the linear chirp of the drive laser pulses, we observe wavelength tuning of the high-harmonic output to both larger and smaller values. Comparing tuning via the gas pressure with the amount of blue shift in the transmitted drive laser spectrum, we conclude that both adiabatic and non-adiabatic effects cause pulse-shaping induced tuning of high harmonics. We obtain a fractional wavelength tuning, Δλ/λ, in the range from -0.007 to + 0.01, which is comparable to what is achieved with standard capillaries of smaller diameter and higher pressures.

Abstract
We report the fabrication, integration, and assessment of sharp diamond tips for ultrasensitive force microscopy experiments. Two types of tips, corresponding to the upper and lower halves of a diamond nanowire, were fabricated by top-down plasma etching from a single-crystalline substrate. The lower, surface-attached halves can be directly integrated into lithographically defined nanostructures, like cantilevers. The upper, detachable halves result in diamond nanowires with a tunable diameter (50-500 nm) and lengths of a few microns. Tip radii were around 10 nm and tip apex angles around 15°. We demonstrate the integration of diamond nanowires for use as scanning tips onto ultrasensitive pendulum-style silicon cantilevers. We find the noncontact friction and frequency jitter to be exceptionally low, with no degradation in the intrinsic mechanical quality factor (Q ≈ 130,000) down to tip-to-surface distances of about 10 nm. Our results are an encouraging step toward further improvement of the sensitivity and resolution of force-detected magnetic resonance imaging.

Abstract
We report on mechanical dissipation measurements carried out on thin (∼100 nm), single-crystal silicon cantilevers with varying chemical surface termination. We find that the 1-2 nm-thick native oxide layer of silicon contributes about 85% to the friction of the mechanical resonance. We show that the mechanical friction is proportional to the thickness of the oxide layer and that it crucially depends on oxide formation conditions. We further demonstrate that chemical surface protection by nitridation, liquid-phase hydrosilylation, or gas-phase hydrosilylation can inhibit rapid oxide formation in air and results in a permanent improvement of the mechanical quality factor between three- and five-fold. This improvement extends to cryogenic temperatures. Presented recipes can be directly integrated with standard cleanroom processes and may be especially beneficial for ultrasensitive nanomechanical force- and mass sensors, including silicon cantilevers, membranes, or nanowires.

Abstract
For exploring the application potential of coherent soft x-ray (SXR) and extreme ultraviolet radiation (XUV) provided by high-harmonic generation, it is important to characterize the central output parameters. Of specific importance are pulse-to-pulse (shot-to-shot) fluctuations of the high-harmonic output energy, fluctuations of the direction of the emission (pointing instabilities), and fluctuations of the beam divergence and shape that reduce the spatial coherence. We present the first single-shot measurements of waveguided high-harmonic generation in a waveguided (capillary-based) geometry. Using a capillary waveguide filled with Argon gas as the nonlinear medium, we provide the first characterization of shot-to-shot fluctuations of the pulse energy, of the divergence and of the beam pointing. We record the strength of these fluctuations vs. two basic input parameters, which are the drive laser pulse energy and the gas pressure in the capillary waveguide. In correlation measurements between single-shot drive laser beam profiles and single-shot high-harmonic beam profiles we prove the absence of drive laser beam-pointing-induced fluctuations in the high-harmonic output. We attribute the main source of high-harmonic fluctuations to ionization-induced nonlinear mode mixing during propagation of the drive laser pulse inside the capillary waveguide.

Abstract
This study aimed to assess the efficacy of a rural community-based integrated
intervention for early prevention and management of chronic obstructive pulmonary
disease (COPD) in China. This 18-year cluster-randomized controlled trial
encompassing 15 villages included 1008 patients (454 men and 40 women in the
intervention group [mean age, 54 ± 10 years]; 482 men and 32 women in the control
group [mean age, 53 ± 10 years]) with confirmed COPD or at risk for COPD. Villages
were randomly assigned to the intervention or the control group, and study
participants residing within the villages received treatment accordingly.
Intervention group patients took part in a program that included systematic health
education, smoking cessation counseling, and education on management of COPD. Control
group patients received usual care. The groups were compared after 18 years regarding
the incidence of COPD, decline in lung function, and mortality of COPD. COPD
incidence was lower in the intervention group than in the control group (10%
vs 16%, <0.05). A decline in lung function was also
significantly delayed in the intervention group compared to the control group of COPD
and high-risk patients. The intervention group showed significant improvement in
smoking cessation compared with the control group, and smokers in the intervention
group had lower smoking indices than in the control group (350 vs
450, <0.05). The intervention group also had a significantly lower cumulative
COPD-related death rate than the control group (37% vs 47%,
<0.05). A rural community-based integrated intervention is effective in reducing
the incidence of COPD among those at risk, delaying a decline in lung function in
COPD patients and those at risk, and reducing mortality of COPD.

Abstract
OBJECTIVE In the early pregnancy, large number of decidual natural killer (dNK) cells are present in decidua, which exhibit distinctive phenotype and functions from peripheral blood NK cells (pNK)1. Unlike the cytotoxic pNK cells, dNK cells display more pronounced characteristics of immune tolerance, which contribute the Th2 bias at the maternal-fetal interface and ensure successful pregnancy2. However, the origin and the differentiation program of dNK still remain unknown. MATERIALS AND METHODS Our previous study has demonstrated that the CXCL12/CXCR4 signal axis is involved in the shaping of Th2 bias at the maternal-fetal interface3,4. RESULTS In this study, we demonstrated the first-trimester human trophoblast cells secrete chemokine CXCL12 that can recruit pNK cells to the decidua. We've also found that the pNK cells differentiate locally under the influence of trophablast cells. After co-culture with trophoblast cells, pNK cells could acquire dNK characteristics phenotypically while compared to the dNK cells; however, the blocking of CXCL12/CXCR4 signal of pNK cells has abrogated the modulation of trophoblast cells on the pNK cells. We've also found that JNK1/2/MAPK and ERK/MAPK signal pathways were required for the modulation of trophoblast cells on the pNK cells. MAPK signal pathway is involved in the functional modulation of human first-trimester trophoblast cells and decidual stromal cells on pNK and dNK cells. CONCLUSIONS Our study has elucidated that CXCL12/CXCR4 can recruit pNK cells to the decidua, then positively modulate pNK cells differentiation into the dNK cells, which thus results in Th2 bias and maternal-fetal immune tolerance.

Abstract
BACKGROUND This phase I study evaluated the safety and efficacy of the oral mTOR inhibitor everolimus in combination with thoracic radiotherapy followed by consolidation chemotherapy in locally advanced or oligometastatic untreated non-small-cell lung cancer (NSCLC). PATIENTS AND METHODS Everolimus dose was escalated in incremental steps [sequential cohorts of three patients until the occurrence of dose-limiting toxicity (DLT)] and administered orally weekly (weekly group: dose of 10, 20 or 50 mg) or daily (daily group: 2.5, 5 or 10 mg), 1 week before, and during radiotherapy until 3.5 weeks after the end of radiotherapy. Two cycles of chemotherapy (cisplatin-navelbine) were administrated 4.5 weeks after the end of radiotherapy. RESULTS Twenty-six patients were included in two centers, 56% had adenocarcinoma and 84% had stage III disease. In the weekly group (12 assessable patients), everolimus could be administered safely up to the maximum planned weekly dose of 50 mg; however, one patient experienced a DLT of interstitial pneumonitis at the weekly dose level of 20 mg. In the daily group (9 assessable patients): one DLT of interstitial pneumonitis with a fatal outcome was observed at the daily dose level of 2.5 mg; two other DLTs (one grade 3 esophagitis and one bilateral interstitial pneumonitis) were found at the daily dose level of 5 mg. Overall there were five patients with G3-4 interstitial pneumonitis related to treatment. Among 22 assessable patients for response, there were 9 (41%) partial response and 7 (32%) stable disease. At a median follow-up of 29 months, the 2-year overall survival and progression-free survival actuarial rates were 31% and 12%, respectively. CONCLUSION In previously untreated and unselected NSCLC patients, the recommended phase II dose of everolimus in combination with thoracic radiotherapy is 50 mg/week. Pulmonary toxicity is of concern and should be carefully monitored to establish the potential role of mTOR inhibitor with concomitant radiotherapy. EUDRACT N 2007-001698-27.

Abstract
Epstein-Barr virus (EBV) causes human lymphoid malignancies, and the EBV product latent membrane protein 1 (LMP1) has been identified as an oncogene in epithelial carcinomas such as nasopharyngeal carcinoma (NPC). EBV can epigenetically reprogram lymphocyte specific processes and induce cell immortalization. However, the interplay between LMP1 and the NPC host cell remains largely unknown. Here, we report that LMP1 is important to establish the Hox gene expression signature in NPC cell lines and tumor biopsies. LMP1 induces repression of several Hox genes in part via stalling of RNA Pol II. Pol II stalling can be overcome by irradiation involving the epigenetic regulator TET3. Furthermore, we report that HoxC8, one of the genes silenced by LMP1, plays a role in tumor growth. Ectopic expression of HoxC8 inhibits NPC cell growth in vitro and in vivo, modulates glycolysis and regulates the expression of TCA-cycle related genes. We propose that viral latency products may repress via stalling key mediators that in turn modulate glycolysis.

Abstract
BACKGROUND All-trans retinoic acid (ATRA) has been tried for the treatment and prevention of a number of epithelial cancers. However, the precise mechanism by which ATRA inhibits the growth of cutaneous squamous cell carcinoma (cSCC) remains elusive. AIMS To determine the suppressive effects of ATRA on the human cSCC cell line SCL-1, and explore the possible mechanisms involved. METHODS SCL-1 cells were treated with ATRA, then cell proliferation was measured by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, while apoptosis and cell cycle progression were analysed by flow cytometry. Protein levels of cell-cycle regulatory proteins and the activation of extracellular signal-regulated kinase (ERK) and Jun kinase (JNK) were detected by western blotting analysis. Transcriptional activity of activator protein (AP)-1 was examined by luciferase reporter assay. RESULTS ATRA inhibited the proliferation of SCL-1 cells and had modest proapoptotic effects. ATRA also induced G1 cell-cycle arrest, inhibited the expression of cyclin D1/cyclin-dependent kinase (CDK)4 and cyclinE/CDK2, and increased the expression of the cyclin-dependent kinase inhibitors p21 and p27. In addition, ATRA significantly decreased the phosphorylation of ERK1/2 and JNK1/2, and inhibited AP-1 transcriptional activity. CONCLUSIONS ATRA induces cell-cycle arrest in human cSCC cells by inhibiting the mitogen-activated protein kinase (MAPK)-AP1 pathway, and could be effective in the prevention and chemotherapy of human cSCC.

Abstract
PMP22 is recently recognized as a key player in a variety of prevalent cancers. In this study, we sought to explore the correlation of peripheral myelin protein 22 (PMP22) expression with cell proliferation, invasion and apoptosis in lung cancer cell line. miR29 was transfected into Anip973 lung adenocarcinoma cell line to interfere the expression of PMP22 using Lipofectamine ® 2000 reagent. Real-time polymerase chain reaction (RT-PCR) and Western blot were performed to determine the expression level of PMP22 at mRNA and protein level. Then MTT, Matrigel transwell assay and flow cytometry were respectively used to explore the proliferation, invasion and apoptosis in Anip973 lung adenocarcinoma cell line in vitro. miR29 could significantly down-regulate the expression level of PMP22 in Anip973 cells not only at mRNA level but also at protein level. Moreover, the proliferation rate, invasive cell number and apoptosis rate of Anip973 cells in miR29 transfected group significantly decreased compared with blank group, while no significant difference existed between control group and blank group. Our study found that suppression of PMP22 expression could inhibit cell proliferation, invasion and apoptosis in lung cancer cells. All these findings suggest that PMP22 may be involved in progression of lung cancer and could be a new therapeutic target for this disease.

Abstract
A kHz repetition rate laser pump-X-ray probe system for ultrafast X-ray diffraction is set up based on a laser-driven plasma X-ray source. A simple and reliable normalization approach has been developed to minimize the impact of large X-ray pulse intensity fluctuation on data quality. It utilizes one single X-ray area detector to record both sample and reference signals simultaneously. Performance of this novel normalization method is demonstrated in reflectivity oscillation measurement of a superlattice sample at sub-ps resolution.

Abstract
BACKGROUND The factors involved in Streptococcus mutans colonization in young children are not clear. The aim of this study was to determine the factors associated with S. mutans colonization in 8- to 32-month-old children. METHODS A group of 225 caries-free 8-month-old children was recruited for the study. They were examined every six months until they were 32 months old to investigate their environmental factors, host factors and bacterial transmission factors. At baseline and during each examination, their teeth were checked for the presence of dental plaque and developmental defects of enamel, and S. mutans plaque status was assessed using a real-time PCR test. RESULTS Eight children (3.6%) showed S. mutans colonization by the age of 8 months. The percentages of colonization were 6.0% at 14 months, 16.2% at 20 months, 26.7% at 26 months, and 33.5% at 32 months. The results showed that females (p = 0.006), children with enamel hypoplasia (p = 0.024), children with low birth weights (p = 0.005), those who consume more sweets (p < 0.001), and those with a higher proportion of visible plaque (p = 0.020 and p = 0.041) were more likely to be colonized by S. mutans. CONCLUSIONS Streptococcus mutans colonization in young children was associated with gender, tooth enamel hypoplasia, low birth weight, frequent consumption of sweets and poor oral hygiene.

Abstract
PURPOSE Squamous cell carcinoma of larynx with subglottic extension (sSCC) is a rare location described to carry a poor prognosis. The aim of this study was to analyze outcomes and feasibility of larynx preservation in sSCC patients. PATIENTS AND METHODS Between 1996 and 2012, 197 patients with sSCC were treated at our institution and included in the analysis. Stage III-IV tumors accounted for 76%. Patients received surgery (62%), radiotherapy (RT) (18%), or induction chemotherapy (CT) (20%) as front-line therapy. RESULTS The 5-year actuarial overall survival (OS), locoregional control (LRC), and distant control rate were 59% (95% CI 51-68), 83% (95% CI 77-89), and 88% (95% CI 83-93), respectively, with a median follow-up of 54.4 months. There was no difference in OS and LRC according to front-line treatments or between primary subglottic cancer and glottosupraglottic cancers with subglottic extension. In the multivariate analysis, age > 60 years and positive N stage were the only predictors for OS (HR 2, 95% CI 1.2-3.6; HR1.9, 95% CI 1-3.5, respectively). A lower LRC was observed for T3 patients receiving a larynx preservation protocol as compared with those receiving a front-line surgery (HR 14.1, 95% CI 2.5-136.7; p = 0.02); however, no difference of ultimate LRC was observed according to the first therapy when including T3 patients who underwent salvage laryngectomy (p = 0.6). In patients receiving a larynx preservation protocol, the 5-year larynx-preservation rate was 55% (95% CI 43-68), with 36% in T3 patients. The 5-year larynx preservation rate was 81% (95% CI 65-96) and 35% (95% CI 20-51) for patients who received RT or induction CT as a front-line treatment, respectively. CONCLUSION Outcomes of sSCC are comparable with other laryngeal cancers when managed with modern therapeutic options. Larynx-preservation protocols could be a suitable option in T1-T2 (RT or chemo-RT) and selected T3 sSCC patients (induction CT).

Abstract
Spinal cord injury (SCI) is a common and serious trauma which lacks efficient treatment. Inhibition of cell death in the trauma area is important for spinal cord protection during this process. In this study, necroptosis inhibitor necrostatin-1 (Nec-1) was used to treat SCI rats, to investigate the role of Nec-1 in the recovery of SCI. Nec-1 was found to reduce lesions, cytokines and reactive oxygen species (ROS), improve pathological conditions and blood supply in the spinal cord trauma area. Further study indicated that Nec-1 could inhibit necroptosis by inhibiting RIP1/3-MLKL recruitment and inhibit apoptosis by inhibiting Caspase 3 and Bax while activating Bcl-2. Ethological performance of SCI rats confirmed improvement and protection of physiological function by Nec-1. Nec-1 as a potential treatment for SCI warrants further study. To our knowledge, this is the first study on the role of Nec-1 in the treatment of traumatic SCI. Our research also found inhibition effects of Nec-1 on apoptosis, not only necroptosis - as reported by most publications.

Abstract
In many biomechanical problems, the availability of a suitable model for the wrapping of muscles when undergoing movement is essential for the estimation of forces produced on and by the body during motion. This is an important factor in the Osteoporotic Virtual Physiological Human project which is investigating the likelihood of fracture for osteoporotic patients undertaking a variety of movements. The weakening of their skeletons makes them particularly vulnerable to bone fracture caused by excessive loading being placed on the bones, even in simple everyday tasks. This paper provides an overview of a novel volumetric model that describes muscle wrapping around bones and other muscles during movement, and which includes a consideration of how the orientations of the muscle fibres change during the motion. The method can calculate the form of wrapping of a muscle of medium size and visualize the outcome within tenths of seconds on commodity hardware, while conserving muscle volume. This makes the method suitable not only for educational biomedical software, but also for clinical applications used to identify weak muscles that should be strengthened during rehabilitation or to identify bone stresses in order to estimate the risk of fractures.

Abstract
BACKGROUND Squamous cell carcinoma of larynx with subglottic extension is a rare location described to carry a poor prognosis. The aim of this study was to analyze outcomes and feasibility of definitive radiotherapy in patients with squamous cell carcinoma. PATIENTS AND METHODS Between 1998 and 2012, 56 patients with squamous cell carcinoma were treated at our institution and included in the analysis. Patients received definitive radiotherapy/chemoradiotherapy alone (63%) or after induction chemotherapy (37%) at our institute. RESULTS The 5-year actuarial overall survival, progression-free survival and specific survival were 64% (CI 95%: 48-90), 45% (CI 95%: 28-61), 88% (CI 95%: 78-98), respectively, with median follow-up of 74 months. The 5-year locoregional control was 69% (CI 95%: 56-83) and the 5-year distant control was 95% (CI 95%: 89-100). There was no difference in overall survival and locoregional control according to front-line treatments or between primary subglottic cancer and glotto-supraglottic cancers with subglottic extension. In the multivariate analysis, performance status of at least 1 and positive N stage were the only predictors for overall survival (hazard ratio [HR] [CI 95%]: 6.5 [1.3-34; P=0.03] and 11 [1.6-75; P=0.02], respectively). No difference of locoregional control was observed according to the first received therapy. The univariate analysis retrieved that T3-T4 patients had a lower locoregional control (HR: 3.1; CI 95%: 1.1-9.2, P=0.04), but no prognostic factor was retrieved in the multivariate analysis. In patients receiving a larynx preservation protocol, 5-year larynx preservation rate was 88% (CI 95%: 78-98), and 58% in T3 patients. The 5-year larynx preservation rate was 91% (CI 95%: 79-100) and 83% (CI 95%: 66-100) for patients who received radiotherapy/chemoradiotherapy or induction chemotherapy as a front-line treatment, respectively. CONCLUSION This analysis suggests that the results for squamous cell carcinoma patients treated with radiotherapy/chemoradiotherapy are comparable to those obtained for other laryngeal tumors. This thus suggests the feasibility of laryngeal preservation protocols for infringement subglottic for selected cases. Further studies are needed to clarify these preliminary data.

Abstract
We report successful introduction of negatively charged nitrogen-vacancy (NV(-)) centers in a 5 nm thin, isotopically enriched ([(12)C] = 99.99%) diamond layer by CVD. The present method allows for the formation of NV(-) in such a thin layer even when the surface is terminated by hydrogen atoms. NV(-) centers are found to have spin coherence times of between T2 ~ 10-100 μs at room temperature. Changing the surface termination to oxygen or fluorine leads to a slight increase in the NV(-) density, but not to any significant change in T2. The minimum detectable magnetic field estimated by this T2 is 3 nT after 100 s of averaging, which would be sufficient for the detection of nuclear magnetic fields exerted by a single proton. We demonstrate the suitability for nanoscale NMR by measuring the fluctuating field from ~10(4) proton nuclei placed on top of the 5 nm diamond film.

Abstract
OBJECTIVE Systemic lupus erythematosus (SLE) is a systemic autoimmune disease typically associated with elevated serum immunoglobulin G (IgG). Hypogammaglobulinemia in SLE patients has been attributed to immunosuppressive treatment or a transient effect associated with nephrotic syndrome. We retrospectively reviewed pediatric SLE patients from a single institution to identify patients with hypogammaglobulinemia and risk factors for hypogammaglobulinemia. METHODS A total of 116 pediatric SLE cases from 1997 to 2011 were reviewed and patients with hypogammaglobulinemia (IgG < 500 mg/dl) were identified. The two cohorts were evaluated for association with age, sex, presence of lupus nephritis at SLE diagnosis, disease activity at diagnosis, initial IgG level, and drug treatment. RESULTS Eighty-six patients were included in our study, with a median age of 15 years and a median follow-up of 39.5 months. Seven percent (six of 86) of patients had hypogammaglobulinemia with a median onset of 27 months (0-72 months) after SLE diagnosis. Significant associations were noted for white race (p value 0.029), male sex (p value 0.009), and the presence of lupus nephritis at SLE diagnosis (p value 0.004). Use of immunosuppressive treatment did not show a statistical association with hypogammaglobulinemia, although two of the patients with hypogammaglobulinemia did receive rituximab. Most patients with hypogammaglobulinemia received intravenous immunoglobulin (IVIG) replacement therapy because of infections and/or concern for infection. CONCLUSION Measurement of immunoglobulin levels during treatment in SLE could help identify patients with hypogammaglobulinemia who might require more aggressive follow-up to monitor for increased risk of infection and need for IVIG treatment. A prospective study is needed to validate associated risk factors identified in this study.

Abstract
INTRODUCTION As one of the key molecules in the extracellular matrix in human conceptus, hyaluronan (HA) has been receiving particular attention. Here, we have investigated the expression and regulation of different molecular weight HA on the biological behaviors of primary human trophoblasts during the first trimester of pregnancy. METHODS The expression of HA and HA synthetase (HAS) by human first trimester trophoblasts was analyzed in placentae from normal pregnancy or miscarriage by immunochemistry and real-time RT-PCR, respectively. ELISA was used to measure the secretion of HA by primary trophoblasts. The effects of HA on the proliferation, apoptosis and invasiveness of trophoblasts were examined. We also investigated the signaling pathways involved in HA activation in human trophoblasts. RESULTS The higher HAS2 expression and HA secretion were observed in normal villi than that of miscarriage, and the primary trophoblasts secreted HA continuously. High molecular weight HA (HMW-HA) and medium molecular weight HA (MMW-HA) promoted proliferation and invasiveness while inhibited apoptosis of trophoblasts. However, low molecular weight HA (LMW-HA) had no obvious effect on the growth or invasiveness of human trophoblasts. In addition, HMW-HA showed more efficiently than MMW-HA on the growth while MMW-HA displayed a more obvious effect on the invasiveness of trophoblasts than HMW-HA. HMW-HA activated PI3K/AKT and MAPK/ERK1/2 signaling pathways in trophoblasts. Blocking PI3K/AKT or MAPK/ERK1/2 signaling inhibited the HA-upregulated growth and invasiveness of human trophoblasts. CONCLUSION Our results suggest that higher level and greater molecular mass of HA can promote trophoblast growth and invasion in an autocrine manner, which was beneficial to placentation and maintenance of human early pregnancy.

Abstract
Distinct human leukocyte antigen (HLA) allele and haplotype distributions occur in the northern and southern Han populations of China. However, different ethnic groups in China show limited regional distributions for many HLA alleles and haplotypes. Therefore, it is necessary and meaningful to study the differences in HLA allele and haplotype distribution for northern and southern ethnic groups of China. A total of 428 unrelated individuals from the Lisu, Nu, Tu and Yugur ethnic populations were genotyped for HLA-A, -B, -C and -DRB1 alleles using the PCR-Luminex typing method. The frequencies of HLA alleles and statistically inferred haplotypes were calculated. A total of 29 HLA-A, 54 HLA-B, 27 HLA-C and 41 HLA-DRB1 alleles were spread throughout these four populations with distinct allele and deduced haplotype frequencies between populations. Some alleles and deduced haplotypes exhibited significantly different distributions between northern (Tu and Yugur) and southern groups (Lisu and Nu). A phylogenetic tree and principal component analysis were used to compare the HLA polymorphism between our dataset and 19 other eastern and southeastern Asian populations. This analysis showed that Lisu and Nu belong to a cluster of southern ethnic groups, while Tu and Yugur are most closely related to other northern groups. Thus, distinct ethnic population histories were revealed by analyzing HLA allelic polymorphisms with the HLA profiles of the Lisu and Nu southern Chinese ethnic groups clearly different from the Tu and Yugur northern ethnic groups. The results will be useful for future association studies of infectious disease and contribute toward a more efficient search of organ/tissue matches for transplantation.

Abstract
X-linked sex-ratio distorters that disrupt spermatogenesis can cause a deficiency in functional Y-bearing sperm and a female-biased sex ratio. Y-linked modifiers that restore a normal sex ratio might be abundant and favored when a X-linked distorter is present. Here we investigated natural variation of Y-linked suppressors of sex-ratio in the Winters systems and the ability of these chromosomes to modulate gene expression in Drosophila simulans. Seventy-eight Y chromosomes of worldwide origin were assayed for their resistance to the X-linked sex-ratio distorter gene Dox. Y chromosome diversity caused males to sire ∼63% to ∼98% female progeny. Genome-wide gene expression analysis revealed hundreds of genes differentially expressed between isogenic males with sensitive (high sex ratio) and resistant (low sex ratio) Y chromosomes from the same population. Although the expression of about 75% of all testis-specific genes remained unchanged across Y chromosomes, a subset of post-meiotic genes was upregulated by resistant Y chromosomes. Conversely, a set of accessory gland-specific genes and mitochondrial genes were downregulated in males with resistant Y chromosomes. The D. simulans Y chromosome also modulated gene expression in XXY females in which the Y-linked protein-coding genes are not transcribed. The data suggest that the Y chromosome might exert its regulatory functions through epigenetic mechanisms that do not require the expression of protein-coding genes. The gene network that modulates sex ratio distortion by the Y chromosome is poorly understood, other than that it might include interactions with mitochondria and enriched for genes expressed in post-meiotic stages of spermatogenesis.

Abstract
OBJECTIVES We analyzed the clinical features of 138 patients with primary immunodeficiency (PID) and performed genetic testing on a subset of patients in order to complete gaps in research on PID in South China and thus improve pediatricians' ability to recognize and diagnose PID. METHODS We performed a retrospective analysis based on the medical records of PID patients hospitalized in our institution between May 1999 and June 2012. Gene sequencing was performed in 59 cases. RESULTS Children with PID usually present with fever and repeated infections that generally affect the respiratory and digestive tracts. Growth retardation is observed in some cases. Of the 138 patients, 113 were boys, median age at onset was 5 months (range, 0-119 months), and age at diagnosis was 10 months (2-159 months). A family history of repeated infection or death of family members in infancy because of recurrent infections was recorded in 20 cases (14.49%). Antibody defects were detected in 48 cases (34.78%), combined immunodeficiency disease in 45 cases (32.61%), and other well-defined immunodeficiency syndromes in 45 cases (32.61%). Of the 59 patients from the genetic subanalysis, 24 (15.94%) had a genetic mutation (x-linked agammaglobulinemia, 8 cases; severe combined immunodeficiency, 8 cases; hyperimmunoglobulin M syndrome, 3 cases; hyperimmunoglobulin E syndrome, 3 cases; chronic granulomatous disease, 2 cases). We detected 4 novel mutations. No relevant mutations were found in the remaining 35 cases.After treatment with intravenous immunoglobulin and anti-infectious agents, 16 patients died in hospital, and 5 cases died after discontinuing treatment (mortality, 15.22%). CONCLUSIONS In recent years, the number of patients with PID has risen gradually in South China. Genetic testing can confirm diagnosis. Since PID seriously affects children's quality of life, it is important to diagnose, treat, and intervene early.We hope our clinical and genetic analyses of children with PID can provide diagnostic guidance for clinicians.
