Abstract
Emerging evidence suggests that a common functional polymorphism, rs4444903 (A>G), in the EGF gene might impact an individual's susceptibility to liver cancer; however, individually published results are inconclusive. This meta-analysis aimed to derive a more precise estimation of the relationship between the EGF rs4444903 polymorphism and liver cancer risk. A literature search was conducted in the PubMed, Embase, Web of Science, and CBM databases from inception through May 1st, 2013. Seven case-control studies were included with a total of 1408 liver cancer cases and 1343 healthy controls. Crude odds ratios (ORs) with 95% confidence intervals (CIs) were calculated. Our meta-analysis results indicated that the G variant of the rs4444903 polymorphism might be associated with an increased risk of liver cancer (G allele vs A allele: OR = 1.25, 95%CI = 1.01-1.56, P = 0.040; GG + AG vs AA: OR = 1.65, 95%CI = 1.27-2.15, P < 0.001; GG vs AA: OR = 1.77, 95%CI = 1.34-2.35, P < 0.001). Further subgroup analysis by ethnicity also showed significant associations between the G variant of the rs4444903 polymorphism and an increased risk of liver cancer among Asian, Caucasian, and African populations. No publication bias was detected in this meta-analysis. In conclusion, the current meta-analysis suggests that the G variant of the rs4444903 polymorphism may increase the risk of liver cancer. The EGF rs4444903 (A>G) polymorphism can be useful as a biomarker in predicting the development of liver cancer.

Abstract
A 35-year-old female patient was diagnosed with pulmonary arterial hypertension (PAH) by right heart catheterization (RHC) in the 3rd month of systemic lupus erythematosus (SLE) duration with high disease activity. Through methylprednisolone pulse therapy, she got total recovery from PAH proven by repeat catheterization and follow-ups. This is the first simultaneously diagnosed, totally recovered, gold standard-proved SLE-PAH case ever reported in the literature. We would like to share this successful case, and at the same time, we want to highlight the relationship between presentation of PAH and active disease manifestations of SLE patients, and to discuss how immune suppressive treatment could benefit this subset of patients.

Abstract
OBJECTIVES To evaluate the performance of a massively parallel sequencing (MPS)-based test in detecting fetal sex chromosome aneuploidy (SCA) and to present a comprehensive clinical counseling protocol for SCA-positive patients. METHODS This was a retrospective study in a large patient cohort of 5950 singleton pregnancies which underwent MPS-based testing as a prenatal screening test for trisomies 21, 18 and 13, with X and Y chromosomes as secondary findings, in Southwest Hospital in China. MPS-based SCA-positive women were offered the choice of knowing whether their SCA results were positive and those who did commenced a two-stage post-test clinical counseling protocol. In Stage 1, general information about SCA was given, and women were given the option of invasive testing for confirmation of findings; in Stage 2, those who had chosen to undergo invasive testing were informed about the specific SCA affecting their fetus and their management options. RESULTS Thirty-three cases were classified as SCA-positive by MPS-based testing. After Stage 1 of the two-stage post-test clinical counseling session, 33 (100%) of these pregnant women chose to know the screening test results, and 25 (75.76%) underwent an invasive diagnostic procedure and karyotype analysis, in one of whom karyotyping failed. In thirteen cases, karyotyping confirmed the MPS-based test results (two X0 cases, seven XXX cases, three XXY cases and one XYY case), giving a positive predictive value of 54.17% (13/24 cases confirmed by karyotyping). After post-test clinical counseling session Stage 2, seven women chose to terminate the pregnancy: one X0 case, two XXX cases, the three XXY cases and the single XYY case. Six women decided to continue with pregnancy: one X0 case and five XXX cases. CONCLUSION Our study showed the feasibility of clinical application of the MPS-based test in the non-invasive detection of fetal SCA. Together with a two-stage post-test clinical counseling protocol, it leads to a well-informed decision-making procedure.

Abstract
Objectives To estimate the prevalence of pulmonary arterial hypertension (PAH) and risk factors for PAH in patients registered in the Chinese SLE Treatment and Research group (CSTAR) database, the first online registry of Chinese patients with systemic lupus erythematosus (SLE). Methods A prospective cross-sectional study of patients with SLE was conducted using the CSTAR registry. Resting transthoracic echocardiography was used to estimate pulmonary artery pressure (PAP); PAH was defined as systolic PAP (PASP) ≥40 mmHg. Patients with interstitial lung disease, valvular disease or cardiomyopathy were excluded because of disease influence on PAP. We explored potential risk factors for PAH including patient characteristics, organ involvement, laboratory findings and SLE disease activity. Results Of 1934 patients with SLE, 74 had PASP with 54.2 ± 17.1 (40,106) mmHg and were diagnosed with probable PAH. The incidences of lupus nephritis, pleuritis, pericarditis, hypocomplementemia, anti-SSA, and anti-ribonucleoprotein (RNP) were significantly higher in patients with PAH than in those without ( p<0.05). SLE disease activity was significantly higher in patients with PAH than in unaffected patients ( p<0.05). Multivariate analysis indicated that pericarditis (odds ratio (OR) = 4.248), pleuritis (OR = 3.061) and anti-RNP (OR = 2.559) were independent risk factors for PAH in patients with SLE ( p<0.05). Conclusions The possible prevalence of PAH was 3.8% in Chinese patients with SLE in the CSTAR registry. The significant association of pericarditis, pleuritis and anti-RNP positivity with PAH suggests that higher disease activity and vasculopathy may both contribute to the development of PAH in SLE, which need be treated aggressively to improve prognosis.

Abstract
Our prior study in multiple myeloma (MM) patients showed increased numbers of plasmacytoid dendritic cells (pDCs) in the bone marrow (BM), which both contribute to immune dysfunction as well as promote tumor cell growth, survival and drug resistance. Here we show that a novel Toll-like receptor (TLR-9) agonist C792 restores the ability of MM patient-pDCs to stimulate T-cell proliferation. Coculture of pDCs with MM cells induces MM cell growth; and importantly, C792 inhibits pDC-induced MM cell growth and triggers apoptosis. In contrast, treatment of either MM cells or pDCs alone with C792 does not affect the viability of either cell type. In agreement with our in vitro data, C792 inhibits pDC-induced MM cell growth in vivo in a murine xenograft model of human MM. Mechanistic studies show that C792 triggers maturation of pDCs, enhances interferon-α and interferon-λ secretion and activates TLR-9/MyD88 signaling axis. Finally, C792 enhances the anti-MM activity of bortezomib, lenalidomide, SAHA or melphalan. Collectively, our preclinical studies provide the basis for clinical trials of C792, either alone or in combination, to both improve immune function and overcome drug resistance in MM.

Abstract
Our goal is to develop a rapid and scalable system for functionally evaluating deregulated genes in multiple myeloma (MM). Here, we forcibly expressed human cMYC and KRAS12V in mouse T2 B cells (IgM(+)B220(+)CD38(+)IgD(+)) using retroviral transduction and transplanted these cells into lethally irradiated recipient mice. Recipients developed plasmacytomas with short onset (70 days) and high penetrance, whereas neither cMYC nor KRAS12V alone induced disease in recipient mice. Tumor cell morphology and cell surface biomarkers (CD138(+)B220(-)IgM(-)GFP(+)) indicate a plasma cell neoplasm. Gene set enrichment analysis further confirms that the tumor cells have a plasma cell gene expression signature. Plasmacytoma cells infiltrated multiple loci in the bone marrow, spleen and liver; secreted immunoglobulins; and caused glomerular damage. Our findings therefore demonstrate that deregulated expression of cMYC with KRAS12V in T2 B cells rapidly generates a plasma cell disease in mice, suggesting utility of this model both to elucidate molecular pathogenesis and to validate novel targeted therapies.

Abstract
Cigarette smoking is one of the most important risk factors for kidney cancer, but the molecular mechanism is poorly understood. To examine the expression change of histone H3 on lysine 27 trimethylase (H3K27me3) demethylases ubiquitously transcribed TPR gene on the X chromosome (UTX) in kidney cancer cell line 786-O after nicotine treatment, quantitative real-time-polymerase chain reaction and western blotting analysis were carried out. These results showed that nicotine can increase UTX messenger RNA and protein levels and also decrease the content of H3K27me3. The decreased content of H3K27me3 may activate specific gene expression and lead to kidney cancer. Future investigation on nicotine induced UTX expression and its epigenetic effect would deepen our understanding on nicotine toxicity and carcinogenicity.

Abstract
Natural killer (NK) cells are characterized by an efficient antitumor activity, and this activity has been exploited as the basis of cancer immunotherapy strategies. Interferon-α (IFN-α) is an important cytokine required for induction of the durable antitumor immune response and is an important stimulator of NK cells. In this study, to augment the efficiency of NK cell cytotoxicity to tumor cells, human IFN-α gene-modified natural killer cell line (NKL) (NKL-IFNα) cells, which could stably secrete IFN-α, were established. We investigated the natural cytotoxicity of NKL-IFNα cells against human hepatocarcinoma cells (HCCs) in vitro and in vivo. NKL-IFNα cells displayed a significantly stronger cytolytic activity against both human HCC cell lines and primary human hepatoma cancer cells compared with parental NKL cells. The increased cytolytic activity of NKL-IFNα cells was associated with the upregulation of cytotoxicity-related genes, such as perforin, granzyme B and Fas ligand, in the NK cells. Moreover, cytokines secreted by NKL-IFNα cells, such as tumor necrosis factor-α and IFN-γ, induced increased expression of Fas on the target HCC cells, and resulted in increased susceptibility of the HCC cells to NK-mediated cytolysis. Encouragingly, NKL-IFNα cells could significantly inhibit HCC tumor growth in a xenograft model and prolonged the survival of tumor-bearing nude mice. These results suggest that IFN-α gene-modified NKL cells could be suitable for the future development of cell-based immunotherapeutic strategies for hepatocellular carcinoma.
