Abstract
The most common type cancer prevailing in pediatric patients worldwide is acute lymphoblastic leukemia (ALL). The characteristic feature of this cancer is the accumulation of immature lymphoid cell in the bone marrow. Further a subtype of ALL namely B-cell precursor (BCP)-ALL has raised in the recent years and is the most common subtype of ALL prevalent in children worldwide. The present review article will put light on the current aspects of BCP ALL including etiology, causative factors, diagnostic and treatment.

Abstract
Ammopiptanthus mongolicus, an evergreen broadleaf legume shrub, can survive under conditions of high and low temperature, extreme salinity, and drought. This attribute makes it an ideal model for studying mechanisms of stress tolerance in plants. However, simple sequence repeat (SSR) resources for this species are insufficient in public databases. In this study, a total of 44,959 unigenes identified from the A. mongolicus transcriptome were used for SSR analysis by MIcroSAtellite (MISA). A total of 13,859 SSRs were found to be distributed within 10,409 unigenes, with an average length of 15 bp and an average density of one SSR per 4.4 kb. There were 222 different motif types in the A. mongolicus transcriptome, and mononucleotide repeats represented the main type, accounting for 44.2% of all SSRs. The (A/T)n repeat was the most frequent motif, accounting for 42.37% of all SSRs. We also performed Gene Ontology functional analysis, Kyoto Encyclopedia of Genes and Genomes database pathway analysis, and eggNOG analysis, and identified 6157, 2301, and 9845 unigenes containing SSRs in these three databases, respectively. The functional categorization of A. mongolicus unigenes containing SSRs revealed that these unigenes represent many transcribed genes with different functions. These data provide sequence information that may be used to improve molecular-assisted markers for the study A. mongolicus genetic diversity.

Abstract
Controversy exists on the relationship between serum thyrotropin (TSH) and blood pressure, and only a few prospective studies are available up to now. The study aimed to investigate the association between serum TSH within the reference range and blood pressure through a 5-year follow-up study. A total of 623 subjects with normal TSH were followed up for 5 years, including the measurement of demographic data, blood pressure, height, weight and serum TSH. Finally, 531 subjects were included in this prospective study. Body mass index (BMI), prevalence of hypertension, and systolic and diastolic blood pressure were all higher at follow-up than at baseline. Adjusted for age, gender, smoking status, BMI and homoeostasis model assessment of insulin resistance (HOMA-IR) at baseline, multiple linear regression analyses found no relationship between serum TSH at baseline and levels of blood pressure at follow-up, but the changes in serum TSH levels during follow-up was positively associated with the changes in systolic blood pressure (B=2.134, P<0.05), which became more significant in women but not significant in men. The change of systolic blood pressure in group of TSH increase >0.5 mIU l-1 was significantly higher than in group of TSH decrease >0.5 mIU l-1 within reference, after adjusting for age, gender, smoking status, BMI and HOMA-IR at baseline. This result became more significant in women, but no statistical significance was observed in men. Co-variation with serum TSH levels and blood pressure was observed during 5-year follow-up among people with normal TSH.

Abstract
To explore the association between rotavirus (RV) infection and histo-blood group antigens (HBGAs), a cross-sectional study was conducted in children hospitalized with diarrhoea in China from November 2014 to February 2015. In total, 424 sets of stool, saliva and buccal cell samples were collected. For the 125 RV-negative samples, 92% (104/125) were secretors/partial secretors, 8% (10/125) were non-secretors. Among the 299 RV-positive samples, 277 were P[8] and 22 were P[4]. All P[4] and P[8] positive individuals were secretors/partial secretors except for one P[8] (0.3%, 1/299), which was a non-secretor. These findings indicate that P[8] and P[4] RVs preferably infect secretors/partial secretors (p <0.001).

Abstract
Accumulating evidence indicates that the lncRNAs play a critical role in cancer progression and metastasis. In this study, we found that MALAT1 upregulation was associated with larger tumor size and lymph-node metastasis, and also correlated with shorter overall survival of lung adenocarcinoma patients. Furthermore, MALAT1 promotes EMT and metastasis of lung adenocarcinoma cells in vitro and in vivo. In particular, MALAT1 upregulated the expression of miR-204 target gene SLUG through competitively 'spongeing' miR-204. In summary we unveil a branch of the MALAT1/miR-204/SLUG pathway that regulates the progression of lung adenocarcinoma.

Abstract
OBJECTIVE To evaluate the safety and efficacy of Enterprise stent in the treatment of severe symptomatic basilar artery atherosclerosis stenosis. METHODS All patients who underwent Enterprise stent for the treatment of symptomatic basilar artery atherosclerotic stenosis in our center from Nov. 2011 to Nov. 2014 were enrolled in the study. Preoperative and postoperative dual antiplatelet drugs and intensive lipid-lowering therapy were given to all the patients. Multi-modality imaging guiding for stent angioplasty was performed in all the patients, including head MRI or CT, CT or MRI perfusion, high resolution MRI for plaque analysis and angiography. Angiography after 6 months was recommended. The main outcome parameters were any stroke or death within 30 days, stroke recurrence in the basilar artery blood supply area during the follow-up period and in-stent restenosis. RESULTS A total of 35 cases were enrolled in the study with operation technical success rate of 100%. The average preoperative and postoperative stenosis rate was (83.0±10.1)% and (28.1±8.9)%. The main perioperative complication and mortality rate was 0. The average follow-up period was (10.6±7.9) months. During follow-up period, only 2 cases (5.7%) of TIA related to the stented artery were observed. In patients with follow-up period more than 6 months, 17 cases (56.7%) underwent cerebral angiography. Restenosis rate was 17.6%. One patient with in-stent restenosis suffered from transient cerebral ischemia and received another Enterprise stenting successfully. CONCLUSION Long term follow-up results show that Enterprise stent for the treatment of symptomatic basilar artery severe stenosis is safe and recurrence of stroke can be prevented effectively.

Abstract
Acute lymphoblastic leukemia (ALL) is the commonest childhood malignancy. Despite therapeutic advancements, relapse of the pathological state in the form of central nervous system (CNS) disease remains a challenge. CNS disease appears to be present at diagnosis in at least 40% of patients. This relapse in the form of CNS disease is one of the major hurdles in achieving complete cure. The present review article aims to discuss the important mechanisms of leukemic entry and infiltration patterns of leukemic cells into the CNS. Also, latest updates in the management strategies of ALL will also be focused in the present article.

Abstract
OBJECTIVE To explore the epidemiologic characteristics of noroviruses isolated in patients with acute gastroenteritis in Hangzhou between March 2014 and April 2015. METHODS Stool specimens and clinical data were collected from 1 109 patients with acute gastroenteritis. Specimens were detected for noroviruses with GⅠand GⅡsubtypes by one-step double real-time RT-PCR. Some of the positive specimens were then randomly selected and amplified by multiplex RT-PCR. Those positive PCR products were sequenced and analyzed phylogenetically for testing the partial capsids of noroviruses. RESULTS Of the 1 109 stool specimens, positive rate of noroviruses was 26.87% (298/1 109). GⅡgenotype was the major viruses with the proportion as 25.52% (283/1 109), while 1.35% (15/1 109) belonged to GⅠgenotypes. There was no significant difference in the noroviruses detection rate of the different genders (P>0.05). However, in different age groups, GⅡgenotypes were predominant types of noroviruses, and the positive rates of GⅡgenotypes were 16.94% (<5 years-old), 19.45% (5-18 years-old) and 32.26% (≥18 years-old), respectively. In different seasons, noroviruses could be detected all year round, with positive rate as 29.67%-37.08% in the highly epidemic seasons (between December and March of the following year). The distribution trends were seen certain difference between noroviruses-GⅡand GⅠtypes. Additionally, results from the sequence analysis demonstrated that GⅡ-4 genotype was the prevalent strain of GⅡ genotypes, clustered into GⅡ-4/Sydney (46.43%, 13/28) and GⅡ-4/2006b (25.0%, 7/28), while GⅠstrains clustered into GⅠ-1. CONCLUSION Noroviruses appeared one of the major pathogens, leading to acute gastroenteritis. G Ⅱgenotypes of noroviruses, especially the G Ⅱ-4/Sydney variant strains and GⅡ-4/2006b variant strains, were considered to be the prevalent strains prevailed in Hangzhou areas from 2014 to 2015.

Abstract
From September 2014 to March 2015, 23 outbreaks of norovirus (NoV) acute gastroenteritis occurred in Jiangsu, China. Partial sequencing of the NoV capsid gene suggested that 16 of the 23 outbreaks were related to a new GII.17 variant. This variant was first detected in sporadic specimens in October 2014, and became predominant in February 2015. Analysis of the RNA-dependent RNA polymerase (RdRp), and complete capsid including the protruding domain P2 sequences confirmed this GII.17 variant as distinct from previously identified GII variants.

Abstract
Mucormycosis is an uncommon infectious complication after renal transplantation and is associated with fatal outcomes. We report 2 cases of transplant renal artery thrombosis and spontaneous rupture caused by mucormycosis. As stenosis, thrombosis, and spontaneous rupture of the transplant renal artery began to occur in both cases after renal transplantation, nephrectomy of the transplanted kidney was performed. Postoperative pathological findings in the transplanted kidney revealed an invasive mucormycosis infection in the renal artery. One patient survived, but the other patient died. This report also presents the diagnosis and treatment processes used for this transplant complication.

Abstract
Sugars acting as fuel energy or as signaling molecules play important roles in plant growth and development. Although sugars associated with early seedling development have been analyzed in detail, few studies have examined the effect of sugar on genome-wide gene transcription. To analyze the role of glucose on the genomic level, we examined the response of seedlings to 5% glucose using RNA-seq technology. High concentrations of glucose significately altered the expression of 863 genes, with 558 upregulated and 305 downregulated genes by more than 2-fold. A large number of genes affected by glucose were involved in metabolic processes and signaling. Transcript levels for many kinases and calcium signals were downregulated. Most transcription factors identified were also involved in glucose signaling. Moreover, many genes related to the auxin, gibberellin, and abscisic acid responses were upregulated or downregulated. Additionally, the K(+), Ca(2+), SO3(-), NO3(-), PO4(3-), amino acid, and sugar transporters were also upregulated or downregulated. These results provide a basic understanding of the glucose-mediated molecular mechanisms in the regulation of early seedling development.

Abstract
What do animals hear? While it remains challenging to adequately assess sensory perception in animal models, it is important to determine perceptual abilities in model systems to understand how physiological processes and plasticity relate to perception, learning, and cognition. Here we discuss hearing in rodents, reviewing previous and recent behavioral experiments querying acoustic perception in rats and mice, and examining the relation between behavioral data and electrophysiological recordings from the central auditory system. We focus on measurements of critical bands, which are psychoacoustic phenomena that seem to have a neural basis in the functional organization of the cochlea and the inferior colliculus. We then discuss how behavioral training, brain stimulation, and neuropathology impact auditory processing and perception.

Abstract
Collagen-induced arthritis (CIA) is a common autoimmune animal model used to study rheumatoid arthritis (RA). The development of CIA involves infiltration of macrophages and neutrophils into the joint, as well as T and B cell responses to type II collagen. In murine CIA, genetically susceptible mice (DBA/1J) are immunized with a type II bovine collagen emulsion in complete Freund's adjuvant (CFA), and receive a boost of type II bovine collagen in incomplete Freund's adjuvant (IFA) 21 days after the first injection. These mice typically develop disease 26 to 35 days after the initial injection. C57BL/6J mice are resistant to arthritis induced by type II bovine collagen, but can develop arthritis when immunized with type II chicken collagen in CFA, and receive a boost of type II chicken collagen in IFA 21 days after the first injection. The concentration of heat-killed Mycobacterium tuberculosis H37RA (MT) in CFA also differs for each strain. DBA/1J mice develop arthritis with 1 mg/ml MT, while C57BL/6J mice require and 3-4 mg/ml MT in order to develop arthritis. CIA develops slowly in C57BL/6J mice and cases of arthritis are mild when compared to DBA/1J mice. This protocol describes immunization of DBA/1J mice with type II bovine collagen and the immunization of C57BL/6J mice with type II chicken collagen.

Abstract
The previous studies found that chronic inflammation related to an increased risk of colorectal cancer (CRC). This study aims to explore the associations of polymorphisms in inflammation-related genes (IL10, IL10RA, IL6R, TNFRSF1A, TNFRSF1B, LTA and IL4) and their interactions with the risk of colorectal cancer among Chinese population. A population-based case-control study including 299 cases and 296 controls was conducted from January 2001 to December 2009. Multivariate unconditional logistic regression was used to analyse the association of nine SNPs in inflammation-related genes with the risk of CRC, colon cancer and rectal cancer, respectively. Generalized multifactor dimensionality reduction (GMDR) was implemented to explore the gene-gene interactions among all SNPs on CRC. A decreased risk of colorectal cancer in subjects with rs1800872 AC genotype of IL10 (OR = 0.643, 95%CI = 0.453, 0.912) or AC/CC genotype (OR = 0.636, 95%CI = 0.457, 0.885) was observed, compared with those with AA genotype. Meanwhile, similar associations were observed between rs1800872 and rectal cancer. Additionally, in rs1061624 of TNFRSF1B gene, AG genotype (OR=0.566; 95% CI= 0.362, 0.885) and AG/GG genotype (OR=0.638; 95% CI=0.420, 0.971) were significantly associated with a decreased risk of rectal cancer, respectively. Our findings indicated that mutants in IL10 and TNFRSF1B genes may change the CRC risk. However, there is no interaction between inflammation-related genes on CRC risk.

Abstract
Patients at the same pathological stage of early esophageal squamous cell carcinoma (ESCC) have significantly different prognoses. The aim of this study was to explore the relationship between specific microRNAs (miRNAs) in two groups of early ESCC patients who had different prognoses at the pT1N0 stage, and to study the prognostic significance of different miRNAs in early ESCC metastasis. We tried to identify prognostic markers that may be helpful in the selection of appropriate treatment for patients with early ESCC. We used TaqMan Human miRNA Arrays to detect and analyze bioinformatically the expression profiles of miRNAs in two groups, and the reverse transcription polymerase chain reaction method to verify the differences in miRNA expression. The miRNA arrays revealed a total of 29 markedly downregulated miRNAs in the survival group compared with the deceased group. Such miRNAs were associated with lympho-vascular invasion and metastasis, and acted as predictive markers of lympho-vascular invasion and metastasis. The detection of these miRNAs forms an important basis for the treatment of early ESCC. It can also help determine those patients with early ESCC who are good candidates for endoscopic resection treatment and those who need additional treatment after endoscopic resection.

Abstract
We analysed the association between influenza A(H7N9) confirmed cases and exposure to poultry in Huzhou city, China. All cases (n=12) had a history of direct exposure to poultry or live poultry markets. We detected A(H7N9)-positive poultry samples from each site that was epidemiologically associated with cases. None of the cases’ close contacts tested positive. After closure of the markets, no new cases were identified, suggesting an epidemiological link between poultry exposure and A(H7N9) virus infection.

Abstract
BACKGROUND AND PURPOSE There are limited studies on the morphologic characteristics of MCA atherosclerotic stenosis. Our aim was to quantitatively assess the remodeling pattern and plaque distribution of atherosclerotic MCAs with 3T high-resolution MR imaging. MATERIALS AND METHODS Eighty-seven consecutive patients with symptomatic atherosclerotic stenoses at the M1 segment of the MCA on DSA (50%-99%) were enrolled. The remodeling index was calculated as the Vessel Area at Maximal Lumen Narrowing/Reference Vessel Area. A remodeling index ≥ 1.0 was defined as positive remodeling, and a remodeling index < 1.0, as negative remodeling. Plaque distribution at the maximal lumen narrowing site was classified on the basis of the involvement of the superior, inferior, dorsal, or ventral MCA wall. RESULTS Forty-three of 87 patients were excluded due to poor imaging quality (n = 8) or scan plane obliquity secondary to a tortuous M1 segment of the MCA or an MCA ostium lesion or angled lesion (n = 35). Of 44 patients in the final analysis, negative remodeling was found in 19 (43.2%) lesions, and positive remodeling, in 25 (56.8%) lesions. At maximal lumen narrowing sites, lesions with negative remodeling had less vessel area, wall area, and percentage of plaque burden (P < .0001) and a lower eccentricity index (P = .023), compared with lesions with positive remodeling. The plaque involved the superior and dorsal walls in 15 (34.1%) of 44 patients. CONCLUSIONS 2D high-resolution MR imaging can help assess the remodeling pattern and plaque distribution of MCA stenosis, but the imaging and postprocessing protocol for remodeling assessment needs to be improved in the tortuous course of the MCA and in MCA ostium or angled lesions.

Abstract
Salivary gland epithelial cells (SGEC) release several cytokines that play important roles in the inflammatory process. In this study, we examined whether capsaicin can modulate cytokine release in SGEC. After cells were stimulated with polyinosinic-polycytidylic acid [poly(I:C)] or lipopolysaccharide (LPS), mRNA transcript and protein levels were detected by reverse-transcriptase-polymerase chain-reaction (RT-PCR), real-time PCR, and enzyme-linked immunosorbent assay (ELISA). These findings demonstrated that the increases in TNFα and IL-6 mRNA transcripts were highest at 3 hrs and 1 hr after incubation with poly(I:C) and LPS, respectively. Pre-treatment of the cells with 10 μµ capsaicin, however, significantly inhibited mRNA transcripts and its protein levels. The simultaneous application of 10 μµ capsazepine with capsaicin did not block the inhibitory effect of capsaicin. Furthermore, the inhibitory effect of capsaicin was also shown in primary cultured cells from TRPV1(-/-) mice. We found that both poly(I:C) and LPS induced IκB-α degradation and phosphorylation, which resulted in NF-κB activation, and capsaicin inhibited this NF-κB pathway. These results demonstrate that SGEC release pro-inflammatory cytokines mediated by TLR, and capsaicin inhibits this process through the NF-κB pathway. This study suggests that capsaicin could potentially alleviate inflammation in salivary glands.

Abstract
12/15-Lipoxygenase (12/15-LO) is an enzyme that converts polyunsaturated fatty acids into bioactive lipid derivatives. In this study, we showed that inhibition of 12/15-LO by baicalein (BA) significantly attenuated clinical severity of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis (MS). Inhibited migration of autoimmune T cells into the central nervous system (CNS) by BA treatment could be attributed to reduced activation of microglia, which was indicated by suppressed phagocytosis, and decreased production of proinflammatory cytokines and chemokines in the CNS. We further observed that inhibition of 12/15-LO with BA led to increased expression of peroxisome proliferator-activated receptor (PPAR)β/δ in microglia of EAE mice. This was confirmed in vitro in primary microglia and a microglia cell line, BV2. In addition, we demonstrated that BA did not affect 12/15-LO or 5-lipoxygenase (5-LO) expression in microglia, but significantly decreased 12/15-LO products without influencing the levels of 5-LO metabolites. Moreover, among these compounds only 12/15-LO metabolite 12-hydroxyeicosatetraenoic acid was able to reverse BA-mediated upregulation of PPARβ/δ in BV2 cells. We also showed that inhibition of microglia activation by PPARβ/δ was associated with repressed NF-κB and MAPK activities. Our findings indicate that inhibition of 12/15-LO induces PPARβ/δ, demonstrating important regulatory properties of 12/15-LO in CNS inflammation. This reveals potential therapeutic applications for MS.

Abstract
CYP2E1 metabolizes ethanol leading to production of reactive oxygen species (ROS) and acetaldehyde, which are known to cause not only liver damage but also toxicity to other organs. However, the signaling pathways involved in CYP2E1 regulation by ethanol are not clear, especially in extra-hepatic cells. This study was designed to examine the role of CYP2E1 in ethanol-mediated oxidative stress and cytotoxicity, as well as signaling pathways by which ethanol regulates CYP2E1 in extra-hepatic cells. In this study, we used astrocytic and monocytic cell lines, because they are important cells in central nervous system . Our results showed that 100 mM ethanol significantly induced oxidative stress, apoptosis, and cell death at 24 h in the SVGA astrocytic cell line, which was rescued by a CYP2E1 selective inhibitor, diallyl sulfide (DAS), CYP2E1 siRNA, and antioxidants (vitamins C and E). Further, we showed that DAS and vitamin C abrogated ethanol-mediated (50 mℳ) induction of CYP2E1 at 6 h, as well as production of ROS at 2 h, suggesting the role of oxidative stress in ethanol-mediated induction of CYP2E1. We then investigated the role of the protein kinase C/c-Jun N-terminal kinase/specificity protein1 (PKC/JNK/SP1) pathway in oxidative stress-mediated CYP2E1 induction. Our results showed that staurosporine, a non-specific inhibitor of PKC, as well as specific PKCζ inhibitor and PKCζ siRNA, abolished ethanol-induced CYP2E1 expression. In addition, inhibitors of JNK (SP600125) and SP1 (mithramycin A) completely abrogated induction of CYP2E1 by ethanol in SVGA astrocytes. Subsequently, we showed that CYP2E1 is also responsible for ethanol-mediated oxidative stress and apoptotic cell death in U937 monocytic cell lines. Finally, our results showed that PKC/JNK/SP1 pathway is also involved in regulation of CYP2E1 in U937 cells. This study has clinical implications with respect to alcohol-associated neuroinflammatory toxicity among alcohol users.

Abstract
INTRODUCTION We found isolated or clustered trophoblasts in the chorionic connective tissue of the extraplacental membranes, and defined this novel histologic feature as the "trophoblast islands of the chorionic connective tissue" (TICCT). This study was conducted to determine the clinical significance of TICCT. METHODS Immunohistochemistry for cytokeratin-7 was performed on the chorioamniotic membranes (N = 2155) obtained from singleton pregnancies of 1199 uncomplicated term and 956 preterm deliveries. The study groups comprised 1236 African-American and 919 Hispanic women. Gestational age ranged from 24(+0) weeks to 41(+6) weeks. Multiple logistic regression analysis was performed to investigate the magnitude of association between patient characteristics and the presence of TICCT. RESULTS The likelihood of TICCT was significantly associated with advancing gestational age both in term (OR: 1.29, 95% CI: 1.16-1.45, p < 0.001) and preterm deliveries (OR: 1.19, 95% CI: 1.07-1.32, p = 0.001) . Hispanic women were less likely than African-American women to have TICCT across gestation in term (OR: 0.23, 95% CI: 0.18-0.31, p < 0.001) and preterm pregnancies (OR: 0.41, 95% CI: 0.29-0.58, p < 0.001). Women with a female fetus were significantly more likely to have TICCT than women with a male fetus, in both term (OR: 1.64, 95% CI: 1.28-2.11, p < 0.001) and preterm gestations (OR: 2.04, 95% CI: 1.46-2.85, p < 0.001). TICCT was 40% less frequent in the presence of chronic placental inflammation [term (OR: 0.60, 95% CI: 0.45-0.81, p = 0.001) and preterm gestations (OR: 0.58, 95% CI: 0.40-0.84, p = 0.003)] and in parous women at term (OR: 0.60, 95% CI: 0.44-0.81, p = 0.001). CONCLUSIONS Our findings suggest that the duration of pregnancy, fetal sex, and parity may influence the behavior of extravillous trophoblast and placental mesenchymal cells.

Abstract
Combined chronic toxicity and carcinogenicity studies of ozokerite (OZK), a natural wax substance used as a food additive for a gum base, were performed in male and female F344 rats. Dietary concentrations of 0%, 0.05%, 0.1% and 0.2% OZK were applied in a 52-week chronic toxicity study and 0%, 0.1% and 0.2% in a 104-week carcinogenicity study. In the chronic toxicity study, treatment with OZK caused a xenobiotic reaction against absorbed OZK, including formation of histiocytosis and granulomas with crystalline material in many organs in all of the treated males and females. Particularly in the liver, granulomatous inflammation was accompanied by hepatocellular vacuolation and changes in the serum biochemical parameters indicative of hepatic disorder. The number and area of glutathione S-transferase placental form (GST-P) positive foci were increased in all of the treated groups of both sexes, suggesting the proliferative effect of OZK. In the carcinogenicity study, the incidence of hepatocellular adenoma and the total tumor incidence in the liver of all of the treated males were significantly increased compared with the controls. In conclusion, long-term exposure to OZK caused systemic chronic inflammation due to a foreign body response. OZK was weakly carcinogenic in the liver of male F344 rats.

Abstract
BACKGROUND Epidemiological studies have suggested an inconsistent relationship between alcohol drinking and risk of all cancer mortality. As far as we know, no meta-analysis has been conducted to explore this issue. PATIENTS AND METHODS We carried out a PubMed search to find relevant articles published before April 2012 in English. Categorical and dose-response meta-analyses were conducted to identify the impact of alcohol drinking on all cancer mortality. Potential sources of heterogeneity were detected by meta-regression and stratification analyses. Sensitivity and cumulative meta-analyses were also carried out. RESULTS Eighteen independent cohort studies met the inclusion criteria. Compared with non/occasional drinkers, the pooled relative risks (RRs) were 0.91 [95% confidence interval (CI) 0.89-0.94] for light, 1.02 (95% CI 0.99-1.06) for moderate, and 1.31 (95% CI 1.23-1.39) for heavy drinkers. Former drinkers presented a higher risk (RR = 1.32, 95% CI 1.15-1.50) than current drinkers (RR = 1.06, 95% CI 0.98-1.16). There was a J-shaped relationship between all cancer mortality and alcohol consumption in males but not in females. CONCLUSIONS This meta-analysis confirms the health hazards of heavy drinking (≥50 g/day) and benefits of light drinking (≤12.5 g/day). Large-sample, well-designed, prospective epidemiological studies, especially on heavy drinking among women, should be developed in future.

Abstract
Patients who have received subtotal esophagectomy for thoracic esophageal cancer must be closely monitored for second primary malignancies. The purpose of this study is to review and assess patients who developed a second primary esophageal cancer in the residual cervical esophagus. Between 1996 and 2010, 10 patients were diagnosed in our hospital with esophageal squamous cell cancer in the residual cervical esophagus after undergoing thoracic esophagectomy and were treated with endoscopic or surgical resection. Data from these patients were reviewed retrospectively. Seven of the 10 patients (70%) had multiple primary carcinoma lesions at the time of their esophagectomy. A second primary cancer in the residual cervical esophagus was detected in eight patients during follow-up endoscopic examinations while the patients were still asymptomatic. Seven of the patients underwent endoscopic resection for a superficial cancer. None of those patients experienced any complications, and all are currently alive and cancer-free. The remaining three patients underwent resection of the cervical esophagus with regional lymph node dissection. Two of those patients experienced severe complications; one subsequently died (hospital death) from pneumonia, 12 months after surgery, while the other died from recurrence of his cancer. The third patient is alive and cancer-free. Early detection of a second primary malignancy in the residual cervical esophagus followed by endoscopic resection is the best treatment strategy for patients who previously received subtotal esophagectomy for thoracic esophageal cancer. Surgical resection puts patients at high risk of mortality or morbidity.

Abstract
mircoRNAs (miRNAs) play important roles on regulation of gene expressions. Aberrant expression of miRNAs was involved in various biological and pathological processes, including tumorigenesis of breast cancer. Single-nucleotide polymorphisms (SNPs) were implicated in altered expression or biological functions of mature miRNAs. To explore the relevance of miRNA polymorphisms and female physiological characteristics to breast cancer risk, SNPs located within hsa-miR-605 (rs2043556), hsa-miR-149 (rs2292832), hsa-miR-27a (rs895819), hsa-miR-196a-2 (rs11614913) and hsa-miR-618 (rs2682818) were selected, and their associations with breast cancer risk were analysed. In addition, associations between physiological characteristics-related factors and breast cancer risk were estimated too. We found that the ones with menarche age less than 16 years had increased breast cancer risk (OR = 2.10, 95% CI: 1.23-3.60). Marginally significant association between rs11614913 CT/CC genotypes and reduced breast cancer risk was observed (OR = 0.65, 95% CI: 0.40-1.06), while no significance was detected about the other miRNA polymorphisms. We concluded that menarche at less than 16 years old increased breast cancer risk, while the genetic variants in miR-196-a-2 might decrease the risk.

Abstract
OBJECTIVES Autoantibodies from the sera of Sjögren's syndrome patients (SS IgG) have been suggested to inhibit muscarinic receptor function. However, the acute nature of such an inhibitory effect remains controversial. In this study, we investigated the acute effects of SS IgG on muscarinic receptor function in human submandibular gland (HSG) cells. METHODS The effects of autoantibodies on muscarinic receptor function were studied using microspectrofluorimetry, whole-cell patch clamp, immunofluorescence confocal microscopy, and a co-immunoprecipitation assay. RESULTS Carbachol (CCh) was found to consistently increase intracellular calcium concentration ([Ca(2+) ](i) ) and activate K(+) current in HSG cells. However, pretreatment of the cells with SS IgG for 5 or 30 min significantly attenuated these responses, with a substantially more prominent effect after 30 min of treatment. Like CCh, adenosine 5'-triphosphate (ATP) also increased [Ca(2+) ](i) and activated K(+) currents in HSG cells, although pretreatment with SS IgG did not affect the cellular response to ATP. CCh was found to reorganize α-fodrin in HSG cells in a Ca(2+) -dependent manner. However, pretreatment with SS IgG prevented the cytoskeletal reorganization of α-fodrin induced by CCh. CONCLUSIONS SS IgG acutely and reversibly inhibited muscarinic receptor function, thereby inhibiting the Ca(2+) mobilization necessary for the activation of K(+) currents and α-fodrin reorganization in HSG cells.

Abstract
BACKGROUND Intercellular adhesion molecule-1 (ICAM-1) is implicated in carcinogenesis. In this study we examined the expression of ICAM-1 in papillary thyroid cancer (PTC). We hypothesized that ICAM-1 correlates with indicators of tumor aggressiveness in PTC. METHODS Thirty-five primary and metastatic PTCs, five follicular adenomas, five Hashimoto thyroiditis, five nodular hyperplasia, and eight normal thyroid tissue samples were analyzed for ICAM-1 gene expression using quantitative reverse-transcription polymerase chain reaction (RT-PCR). ICAM-1 gene expression was analyzed at protein level by immunohistochemistry (IHC) using a semiquantitative score. Gene expression and intensity levels were correlated with markers of tumor aggressiveness including BRAF V600E mutation, tumor size, extrathyroidal extension (ETE), angiolymphatic invasion, and lymph node metastasis. RESULTS ICAM-1 gene expression was higher in PTC (p = 0.01) and lymph node metastases (p = 0.03) when compared with benign tumors and Hashimoto's. Furthermore, PTCs exhibiting BRAF V600E mutation (p = 0.01), ETE (p < 0.01), and lymph node metastasis (p = 0.02) were associated with higher ICAM-1 levels. Gene expression correlated with protein levels on IHC. Additionally, poorly differentiated thyroid carcinoma had a higher ICAM-1 intensity score compared with well-differentiated carcinoma (p = 0.03). CONCLUSIONS ICAM-1 expression is upregulated in papillary thyroid carcinoma. Furthermore, ICAM-1 upregulation correlated with aggressive tumor features such as BRAF V600E mutation, ETE, and lymph node metastasis, suggesting that ICAM-1 plays a role in thyroid cancer progression.
