The aim of this study is to reveal the relation among villin 2, Wnt/β-catenin, andadipogenesis by adding appropriate lithium chloride (LiCl). The study comprises three parts: theselection of LiCl concentration, the effect of LiCl on adipocyte differentiation during and afterdifferentiation induction. By comprehensively analyzing the results of the experiments, we proved thatLiCl can inhibit adipocyte differentiation and enhance villin 2 and β-catenin expressions not only duringdifferentiation induction but also after it. Moreover, villin 2 has a significant impact on β-catenin. Wesuggest that villin 2 may participate in Wnt/β-catenin signaling.

MYB-NFIB fusion and NOTCH1 mutation are common hallmark genetic events in salivary gland adenoid cystic carcinoma (SACC). However, abnormal expression of MYB and NOTCH1 is also observed in patients without MYB-NFIB fusion and NOTCH1 mutation. Here, we explore in-depth the molecular mechanisms of lung metastasis through single-cell RNA sequencing (scRNA-seq) and exome target capture sequencing in two SACC patients without MYB-NFIB fusion and NOTCH1 mutation. Twenty-five types of cells in primary and metastatic tissues were identified via Seurat clustering and categorized into four main stages ranging from near-normal to cancer-based on the abundance of each cell cluster in normal tissue. In this context, we identified the Notch signaling pathway enrichment in almost all cancer cells; RNA velocity, trajectory, and sub-clustering analyses were performed to deeply investigate cancer progenitor-like cell clusters in primary tumor-associated lung metastases, and signature genes of progenitor-like cells were enriched in the “MYC_TARGETS_V2” gene set. In vitro, we detected the NICD1-MYB-MYC complex by co-immunoprecipitation (Co-IP) and incidentally identified retinoic acid (RA) as an endogenous antagonist of genes in the “MYC_TARGETS_V2” gene set. Following this, we confirmed that all-trans retinoic acid (ATRA) suppresses the lung metastasis of SACC by correcting erroneous cell differentiation mainly caused by aberrant NOTCH1 or MYB expression. Bioinformatic, RNA-seq, and immunohistochemical (IHC) analyses of primary tissues and metastatic lung tissues from patients with SACC suggested that RA system insufficiency partially promotes lung metastasis. These findings imply the value of the RA system in diagnosis and treatment.

SiC/SiOx coaxial nanowires were rapidly synthesized via directmicrowave irradiation in low vacuum atmosphere. During the preparationprocess, only graphite, silicon, silicon dioxide powders were used as rawmaterials and iron-containing substance was employed as catalyst. Comprehensive characterizations were employed to investigate themicrostructure of the products. The results showed that a great quantityof coaxial nanowires with uniform sizes and high aspect ratio had beensuccessfully achieved. The coaxial nanowires consist of a silicon oxide(SiOx) shell and a β-phase silicon carbide (β-SiC) core that exhibited inspecial tube brush like. In additional, nearly all the products wereachieved in the statement of pure SiC/SiOx coaxial nanowires withoutthe existence of metallic catalyst, indicating that the self-removal of iron(Fe) catalyst should be occurred during the synthesis process. Photoluminescence (PL) spectral analysis result indicated that suchnovel SiC/SiOx coaxial nanowires exhibited significant blue-shift. Besides, the measurement results of field-emission (FE) demonstratedthat the SiC/SiOx coaxial nanowires had ultralow turn-on field andthreshold field with values of 0.2 and 2.1 V/μm, respectively. The heterojunctionstructure formed between SiOx shell and SiC core, lots ofemission sites, as well as clear tips of the nanowires were applied toexplain the excellent FE properties.

The aim of this study is to reveal the relation among villin 2, $Wnt/{\beta}-catenin$, and adipogenesis by adding appropriate lithium chloride (LiCl). The study comprises three parts: the selection of LiCl concentration, the effect of LiCl on adipocyte differentiation during and after differentiation induction. By comprehensively analyzing the results of the experiments, we proved that LiCl can inhibit adipocyte differentiation and enhance villin 2 and ${\beta}-catenin$ expressions not only during differentiation induction but also after it. Moreover, villin 2 has a significant impact on ${\beta}-catenin$. We suggest that villin 2 may participate in $Wnt/{\beta}-catenin$ signaling.

Objective: To establish the prevalence and distribution profile of esophageal squamous cell carcinomas (ESCCs) over a 22-yr period in North China. Methods: Using endoscopy for primary diagnosis and histological analysis for the further confirmation, a total of 74,854 ESCC patients aged 20-89 between January 1985 and December 2006 were investigated to analyze the epidemiological profile including prevalence rates, distribution of age-of-onset, gender and geographical area of ESCC in Luoyang, the highest incidence area of North China. Results: A total of 4092 cases of ESCC were finally diagnosed among 74,854 patients who had their first endoscopies. The prevalence among males was higher than that among females (p<0.01), resulting in an overall male:female OR of 1.2 (95%CI, 1.2-1.3). The prevalence in rural areas was higher than in urban areas (p<0.01), resulting in an overall rural:urban OR of 2.6 (95%CI, 2.4-2.9). The rural:urban ORs and the 95% CI increased continuously from 2.6, 2.3-3.0 to 2.7, 2.2-3.3, respectively, for 4 consecutive periods during the 22-yr study period. Moreover, the median age of onset among females was higher than that among males (p<0.01). For both sexes and in both areas, the prevalence rates declined and the median age of onset rose for 4 consecutive periods in the 22-yrs time frame (p<0.01). Conculsions: These data reveal the epidemiological profile of ESCC in the area of North China, and suggest that urban areas and rural people account for a growing proportion of the ESCC patients although the prevalence of ESCC significantly declined and the median age-of-onset postponed over the 22-yrs period. Moreover, the prevalence status of ESCC in rural areas also underlines the need for public health initiatives aimed at reducing risk factors of this fatal disease.

Two single nucleotide polymorphisms (SNPs), rs2280788 (-28C[G) and rs2107538 (-403G[A), in the promoter region of chemokine (C–C motif) ligand 5 (CCL5) was reported to be involved in the immunoglobulin E (IgE) expression and IgE-mediated allergic reactions. This study was to investigate the characteristics of total serum IgE level, specific allergen sensitivities and the two SNPs in the allergic skin disease (ASD) patients. ASD patients visiting the dermatological outpatient department of a local hospital were included with certain criteria, and the fasting venous blood was sampled for analysis. Total serum IgE was assayed with an ELISA kit, and 14 kinds of allergen-specific IgE were tested with an allergen screening system. The polymerase chain reaction–restriction fragment length polymorphism method was used to analyze the two SNPs. Among the finally included 437 patients aged from 16 to 85 years, 68.2 % was positive for the total serum IgE, 49.2 % was positive for at least one of the assayed allergen-specific IgE, and 35.0 % was sensitive to house dust mite. In the SNPs analysis, the GG/(GA?AA) ratio and G/A ratio for the -403G[A locus in the male and/or female C45 years subgroup were significantly lower in the total serum IgE positive patients than in the negative patients (P\0.05). Weak linkage disequilibrium was found between -403A and -28C alleles in male subgroups adjusted by age. Conclusively, house dust mite was the most common allergen in ASD patients, and -403A allele of CCL5 promoter was a risk factor for IgE-mediated sensitization.

Background and Aim: Laparoscopic and open rectum surgery for rectal cancer remains controversial. This systematic review compared the short-term and long-term efficiency and complications associated with laparoscopic and open resection for rectal cancer. Materials and Methods: We searched PubMed, Embase, Cochrane Library, ISI Web of Knowledge and the China Biology Medicine Database to identify potential randomized controlled trials from their inception to March 31, 2014 without language restriction. Additional articles were identified from searching bibliographies of retrieved articles. Two reviewers independently assessed the full-text articles according to the pre-specified inclusion and exclusion criteria as well as the methodological quality of included trials. The meta-analysis was performed using RevMan 5.2. Results: A total of 16 randomized controlled trials involving 3,045 participants (laparoscopic group, 1,804 cases; open group, 1,241 cases) were reviewed. Laparoscopic surgery was associated with significantly lower intraoperative blood loss, earlier return of bowel movement and reduced length of hospital stay as compared to open surgery, although with increased operative time. It also showed an obvious advantage for minimizing late complications of adhesion-related bowel obstruction. Importantly, there were no significant differences in other postoperative complications, oncological clearance, 3-year and 5-year or 10 year recurrence and survival rates between two procedures. Conclusions: On the basis of this meta-analysis we conclude that laparoscopic surgery has advantages of earlier postoperative recovery, less blood loss and lower rates of adhesion-related bowel obstruction. In addition, oncological outcome is comparable after laparoscopic and open resection for rectal cancer.
