[Mechanism of Sanhuang Decoction in alleviating dextran sulfate sodium induced ulcerative colitis in mice with Candida albicans colonization:based on high-throughput transcriptome sequencing].

This study explored the mechanism of Sanhuang Decoction(SHD) in treating dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) in mice with Candida albicans(Ca) colonization via high-throughput transcriptome sequencing. Specifically, the animal model was established by oral administration of 3.0% DSS for 7 days followed by intragastrical administration of Ca suspension at 1.0 × 10~8 cells for 4 days and then the mice were treated with SHD enema for 7 days. Afterwards, the general signs were observed and the disease activity index(DAI) was recorded every day. After mice were sacrificed, colon length and colon mucosa damage index(CMDI) were determined and the histomorphology was observed with the HE staining method. The fungal loads of feces were detected with the plate method. Anti-saccharomyces cerevisiae antibody(ASCA) and ß-1,3-glucan in serum, and TNF-α, IL-1ß, and IL-6 in serum and colon were detected by ELISA. High-throughput RNA sequencing method was adopted to identify transcriptome of colon tissues from the control, model and SHD(15.0 g·kg~(-1)) groups. Differentially expressed genes(DEGs) among groups were screened and the GO and KEGG pathway enrichment analysis of the DEGs was performed. The expression levels of NLRP3, ASC, caspase-1, and IL-1ß genes related to the NOD-like receptor signaling pathway which involved 9 DEGs, were examined by qRT-PCR and Western blot. The results demonstrated that SHD improved the general signs, decreased DAI and Ca loads of feaces, alleviated colon edema, erosion, and shortening, and lowered the content of ß-1,3-glucan in serum and TNF-α, IL-1ß, and IL-6 in serum and colon tissues of mice. Transcriptome sequencing revealed 383 DEGs between SHD and model groups, which were mainly involved in the biological processes of immune system, response to bacterium, and innate immune response. They were mainly enriched in the NOD-like signaling pathway, cytokine-cytokine interaction pathway, and retinol metabolism pathway. Moreover, SHD down-regulated the mRNA and protein levels of NLRP3, caspase-1, and IL-1ß. In a word, SHD ameliorates DSS-induced UC in mice colonized with Ca, which probably relates to its regulation of NOD-like receptor signaling pathway.

[Therapeutic effect of cinnamaldehyde on ulcerative colitis in mice induced by dextran sulfate sodium with Candida albicans colonization and its effect on dectin-1/TLRs/NF-κB signaling pathway].

To observe the efficacy of cinnamaldehyde on dextran sulfate sodium(DSS)-induced ulcerative colitis(UC) with Can-dida albicans(Ca) colonization and its effect on dectin-1/TLRs/NF-κB signaling pathway in mice. C57 BL/6 mice were randomly divided into normal group, DSS group, DSS+Ca group, cinnamaldehyde group and mesalazine group. Mice in DSS+Ca group were given Ca(1×10~8 CFU per mouse) through intragastrical administration for 4 consecutive days and then distilled water with 3.0% DSS for 7 consecutive days. In cinnamaldehyde group and mesalazine group, in addition to the induction method of the DSS+Ca group, mice were given 75 mg·kg~(-1) cinnamaldehyde and 200 mg·kg~(-1) mesalazine accompanied with 3.0% DSS for 7 consecutive days, respectively. Mice in normal group and DSS group were correspondingly administered with distilled water. The general conditions of the mice were observed daily, the diseased activity index(DAI) score was calculated, and fungal loads of feces were detected by plate method. The mice were sacrificed on day 12, colon length was measured, colon mucosa damage index(CMDI) score was calculated, and histopathological analysis was carried out by HE staining. Anti-saccharomces cerevisiae antibody(ASCA) and ß-1,3-glucan in serum, and TNF-α, IL-1ß, IL-6, IL-8, IL-10 in serum and colon tissue were detected by ELISA. The contents of ß-1,3-glucan and macrophage infiltration in colon tissues were examined by immunofluorescence staining. The protein expressions of dectin-1, TLR2, TLR4 and NF-κB were detected by Western blot and immunohistochemistry staining. The results showed that cinnamaldehyde could significantly improve the general conditions of UC mice with Ca colonization, decrease DAI and histopathological scores, reduce intestinal mucosal congestion, erosion and colon shortening, decrease Ca load in mouse feces and tissues, down-regulate the contents of ASCA and ß-1,3-glucan in serum, reduce the contents of TNF-α, IL-1ß, IL-6, IL-8 and increase IL-10 in serum and colon tissues, inhibit macrophages infiltration and down-regulate the protein expression of dectin-1, TLR2, TLR4 and NF-κB in colon tissue. These results suggested that cinnamaldehyde had a therapeutic effect on UC mice with Ca colonization, which might be related to the inhibition of Ca proliferation, the regulation of dectin-1/TLRs/NF-κB signaling pathways and the coordination of the balance between pro-inflammatory and anti-inflammatory factors.

Extracellular Histone Promotes Prostate Cancer Migration and Epithelial-Mesenchymal Transition through NF-κB-Mediated Inflammatory Responses.

INTRODUCTION: This study aims to explore the relationship betweenextracellular histone and prostate cancer and its mechanism. METHODS: Migration of prostate cancer cells was detected by Transwell. Inflammatory factor expression was investigated by ELISA. Epithelial-mesenchymal transition and expression of NF-κB pathway-related proteins were investigated using Western blotting. RESULTS: Under the induction of extracellular histones, the migration rate of prostate cancer cells and the levels of IL-1ß, TNF-α, and IL-6 were notably enhanced. Then, expression of E-cadherin was significantly down-regulated, while levels of N-cadherin, vimentin, ß-catenin, Snail, p-p65 and p-IκBα were significantly up-regulated, which was reversed by PDTC (pyrrolidine dithiocarbamate). CONCLUSION: Extracellular histone significantly promotes the progression of prostate cancer cells via NF-κB pathway-mediated inflammatory responses, which may serve as a novel target for treating prostate cancer.

Red blood cell distribution width and neutrophil to lymphocyte ratio are correlated with disease activity of dermatomyositis and polymyositis.

BACKGROUND: Previous studies indicated that both red blood cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) were useful indices in assessing the disease activity of autoimmune diseases. However, the evidence for the association between RDW, NLR and dermatomyositis (DM) and polymyositis (PM) is limited. The aim of this study is to investigate the association between the disease activity of PM/DM and both RDW and NLR. METHODS: Medical records of 114 PM/DM patients and 114 healthy controls were retrospectively reviewed, and their RDW, NLR and myositis disease activity assessment visual analogue scale (MYOACT) on admission were extracted. The correlations between RDW, NLR and MYOACT were analyzed using the Spearman approach and multivariable model. RESULTS: PM/DM patients had significantly higher RDW and NLR. Increased RDW in PM/DM patients was not completely attributed to decreased hemoglobin or therapeutic agents. Both RDW and NLR are independently and positively correlated MYOACT. CONCLUSION: Both RDW and NLR are useful indices in assessing the disease activity of PM/DM.

Association of SLC22A4 gene polymorphism with Rheumatoid arthritis in the Chinese population.

Rheumatoid arthritis (RA) is a chronic inflammatory disease with complex genetic factors. Single-nucleotide polymorphisms (SNPs) in the SLC22A4 gene have been previously reported to be associated with RA in Japanese but not European populations. This study further investigated the association of SLC22A4 polymorphisms, in particular slc2F1/slc2F2, with RA in the Chinese population, the largest Asian population. A total of 160 human subjects with 95 RA patients and 65 healthy controls were genotyped for slc2F1-G/A and slc2F2-C/T polymorphisms. The results showed that there was a significant difference in the genotype distribution of these two polymorphisms between the two groups. In addition, the presence of slc2F1 A allele and slc2F2 T allele carries a 1.93-fold and 2.14-fold increased risk for anticyclic citrullinated peptide (CCP) positivity, respectively. Overall, this study provided evidence that SLC22A4 gene polymorphisms played important roles in the etiology of RA in the largest Asian population, the Chinese population.

Cichoric acid ameliorates sepsis-induced acute kidney injury by inhibiting M1 macrophage polarization.

Cichoric acid (CA), a widely utilized polyphenolic compound in medicine, has garnered significant attention due to its potential health benefits. Sepsis-induced acute kidney disease (AKI) is related with an elevated risk of end-stage kidney disease (ESKD). However, it remains unclear whether CA provides protection against septic AKI. The aim of this study is to investigated the protective effect and possible mechanisms of CA against LPS-induced septic AKI. Sepsis-induced AKI was induced in mice through intraperitoneal injection of lipopolysaccharide (LPS), and RAW264.7 macrophages were incubated with LPS. LPS exposure significantly increased the levels of M1 macrophage biomarkers while reducing the levels of M2 macrophage indicators. This was accompanied by the release of inflammatory factors, superoxide anion production, mitochondrial dysfunction, activation of succinate dehydrogenase (SDH), and subsequent succinate formation. Conversely, pretreatment with CA mitigated these abnormalities. CA attenuated hypoxia-inducible factor-1α (HIF-1α)-induced glycolysis by lifting the NAD+/NADH ratio in macrophages. Additionally, CA disrupted the K (lysine) acetyltransferase 2A (KAT2A)/α-tubulin complex, thereby reducing α-tubulin acetylation and subsequently inactivating the NLRP3 inflammasome. Importantly, administration of CA ameliorated LPS-induced renal pathological damage, apoptosis, inflammation, oxidative stress, and disturbances in mitochondrial function in mice. Overall, CA restrained HIF-1α-mediated glycolysis via inactivation of SDH, leading to NLRP3 inflammasome inactivation and the amelioration of sepsis-induced AKI.

Bacteroides uniformis Ameliorates Carbohydrate and Lipid Metabolism Disorders in Diabetic Mice by Regulating Bile Acid Metabolism via the Gut-Liver Axis.

BACKGROUND: Type 2 diabetes mellitus (T2DM) is a metabolic syndrome characterized by chronic inflammation, insulin resistance, and islet cell damage. The prevention of T2DM and its associated complications is an urgent public health issue that affects hundreds of millions of people globally. Numerous studies suggest that disturbances in gut metabolites are important driving forces for the pathogenesis of diabetes. However, the functions and mechanisms of action of most commensal bacteria in T2DM remain largely unknown. METHODS: The quantification of bile acids (BAs) in fecal samples was performed using ultra-performance liquid chromatography-tandem mass spectrometer (UPLC-MS/MS). The anti-diabetic effects of Bacteroides uniformis (B. uniformis) and its metabolites cholic acid (CA) and chenodeoxycholic acid (CDCA) were assessed in T2DM mice induced by streptozocin (STZ) plus high-fat diet (HFD). RESULTS: We found that the abundance of B. uniformis in the feces and the contents of CA and CDCA were significantly downregulated in T2DM mice. B. uniformis was diminished in diabetic individuals and this bacterium was sufficient to promote the production of BAs. Colonization of B. uniformis and intragastric gavage of CA and CDCA effectively improved the disorder of glucose and lipid metabolism in T2DM mice by inhibiting gluconeogenesis and lipolysis in the liver. CA and CDCA improved hepatic glucose and lipid metabolism by acting on the Takeda G protein-coupled receptor 5 (TGR5)/adenosine monophosphate-activated protein kinase (AMPK) signaling pathway since knockdown of TGR5 minimized the benefit of CA and CDCA. Furthermore, we screened a natural product-vaccarin (VAC)-that exhibited anti-diabetic effects by promoting the growth of B. uniformis in vitro and in vivo. Gut microbiota pre-depletion abolished the favorable effects of VAC in diabetic mice. CONCLUSIONS: These data suggest that supplementation of B. uniformis may be a promising avenue to ameliorate T2DM by linking the gut and liver.

Vaccarin alleviates septic cardiomyopathy by potentiating NLRP3 palmitoylation and inactivation.

BACKGROUND: Sepsis often leads to significant morbidity and mortality due to severe myocardial injury. As is known, the activation of NOD-like receptor family pyrin domain-containing 3 (NLRP3) inflammasome crucially contributes to septic cardiomyopathy (SCM) by facilitating the secretion of interleukin (IL)-1ß and IL-18. The removal of palmitoyl groups from NLRP3 is a crucial step in the activation of the NLRP3 inflammasome. Thus, the potential inhibitors that regulate the palmitoylation and inactivation of NLRP3 may significantly diminish sepsis-induced cardiac dysfunction. PURPOSE: The present study sought to explore the effects of the prospective flavonoid compounds targeting NLRP3 on SCM and to elucidate the associated underlying mechanisms. STUDY DESIGN: The palmitoylation and activation of NLRP3 were detected in H9c2 cells and C57BL/6 J mice. METHODS/RESULTS: Echocardiography, histological staining, western blotting, co-immunoprecipitation, qPCR, ELISA and network pharmacology were used to assess the impact of vaccarin (VAC) on SCM in mice subjected to lipopolysaccharide (LPS) injection. From the collection of 74 compounds, we identified that VAC had the strongest capability to suppress NLRP3 luciferase report gene activity in cardiomyocytes, and the anti-inflammatory characteristics of VAC were further ascertained by the network pharmacology. Exposure of LPS triggered apoptosis, inflammation, oxidative stress, mitochondrial disorder in cardiomyocytes. The detrimental alterations were significantly reversed upon VAC treatment in both septic mice and H9c2 cells exposed to LPS. In vivo experiments demonstrated that VAC treatment alleviated septic myocardial injury, indicated by enhanced cardiac function parameters, preserved cardiac structure, and reduced inflammation/oxidative response. Mechanistically, VAC induced NLRP3 palmitoylation to inactivate NLRP3 inflammasome by acting on zDHHC12. In support, the NLRP3 agonist ATP and the acylation inhibitor 2-bromopalmitate (2-BP) prevented the effects of VAC. CONCLUSION: Our findings suggest that VAC holds promise in protecting against SCM by mitigating cardiac oxidative stress and inflammation via priming NLRP3 palmitoylation and inactivation. These results lay the solid basis for further assessment of the therapeutic potential of VAC against SCM.

Gut microbiome and metabolites mediate the benefits of caloric restriction in mice after acute kidney injury.

The role of gut microbiome in acute kidney injury (AKI) is increasing recognized. Caloric restriction (CR) has been shown to enhance the resistance to ischemia/reperfusion injury to the kidneys in rodents. Nonetheless, it is unknown whether intestinal microbiota mediated CR protection against ischemic/reperfusion-induced injury (IRI) in the kidneys. Herein, we showed that CR ameliorated IRI-elicited renal dysfunction, oxidative stress, apoptosis, and inflammation, along with enhanced intestinal barrier function. In addition, gut microbiota depletion blocked the favorable effects of CR in AKI mice. 16S rRNA and metabolomics analysis showed that CR enriched the gut commensal Parabacteroides goldsteinii (P. goldsteinii) and upregulated the level of serum metabolite dodecafluorpentan. Intestinal colonization of P. goldsteinii and oral administration of dodecafluorpentan showed the similar beneficial effects as CR in AKI mice. RNA sequencing and experimental data revealed that dodecafluorpentan protected against AKI-induced renal injury by antagonizing oxidative burst and NFκB-induced NLRP3 inflammasome activation. In addition, we screened and found that Hamaudol improved renal insufficiency by boosting the growth of P. goldsteinii. Our results shed light on the role of intestinal microbiota P. goldsteinii and serum metabolites dodecafluorpentan in CR benefits to AKI.

Molecular epidemiological survey of hemoglobinopathies in the Wuxi region of Jiangsu Province, eastern China.

In order to determine the prevalence and molecular characterization of hemoglobinopathies in the Wuxi region of Jiangsu Province in the People's Republic of China (PRC), a total of 10,297 healthy people selected from a regional hospital were screened. Hemoglobin (Hb) electrophoresis, complete blood cell (CBC) count, polymerase chain reaction (PCR), DNA sequencing, reverse dot-blot and multiplex ligation-dependent probe amplification (MLPA) were used to detect Hb variants, thalassemias and hereditary persistence of fetal Hb (HPFH). Two thousand and twenty-one adult subjects were screened for thalassemia, five cases were identified as α-thalassemia (α-thal) carriers including three cases of the -α(3.7) (rightward) deletion, one case of the - -(SEA) deletion and one case of ß-thal [IVS-II-654 (C>T), (HBB: c.316-197C>T)]. The incidence of Hb variants, thalassemia and HPFH/δß-thal were 0.136% (14/10,297), 0.25% (5/2021) and 0.0001% (1/10,297), respectively. Eight genotypes of Hb variants were found, including Hb E [ß26(B8)Glu→Lys, GAG>AAG; HBB: c.79G>A], Hb J-Bangkok [ß56(D7)Gly→Asp (GGC>GAC); HBB; c.170G>A], Hb G-Coushatta [ß22(4)Glu→Ala (GAA>GCA); HBB: c.68A>C], Hb Queens [α34(B15)Leu→Arg (CTG>CGG) (α2 or α1); HBA2: c.104T>G (or HBA1)], Hb I [α16(A14)Lys→Glu, AAG>GAG (α1); HBA1: c.49A>G], Hb Beijing [α16(A14)Lys→Asn (AAG>AAC or AAT) (α2 or α1); HBA2: c.51G>C (or HBA1) or 51G>T (or HBA1)], Hb Ube-2 [α68(E17)Asn→Asp (AAC>GAC) (α2 or α1); HBA2: c.205A>G (or HBA1)] and Hb G-Taipei [ß22(B4)Glu→Gly (GAA>GGA); HBB: c.68A>G]. A Sicilian δß(0)-thal, identified for the first time in Asia, was also found in this survey.

A highly active catalytic system for Suzuki-Miyaura cross-coupling reactions of aryl and heteroaryl chlorides in water.

An easily available Pd(OAc)(2)/(2-mesitylindenyl)dicyclohexylphosphine/Me(octyl)(3)N(+)Cl(-)/K(3)PO(4)·3H(2)O catalytic system was developed and it shows high catalytic activity in the Suzuki-Miyaura cross-coupling reaction of a diverse array of aryl and heteroaryl chlorides in water. Notably, this catalytic system also works with ultra-low loading of the catalyst with high turnover numbers.

Short-term outcomes of near-infrared imaging using indocyanine green in laparoscopic lateral pelvic lymph node dissection for middle-lower rectal cancer: A propensity score-matched cohort analysis.

Laparoscopic lateral pelvic lymph node dissection (LPND) is limited by complex neurovascular bundles in the narrow pelvic sidewall and various post-operative complications. Indocyanine green (ICG) has been applied to increase the number of harvested lymph nodes and reduce the injury of irrelevant vessels in patients with rectal cancer. However, few studies on the recurrence rate of ICG fluorescence imaging-guided laparoscopic LPND were reported. This retrospective study enrolled 50 middle- low rectal cancer patients who were treated by LPND. After propensity score matching, 20 patients were matched in each of the indocyanine green (ICG) guided imaging group (ICG group) and non-ICG guided imaging group (non-ICG group). The average follow-up time was 13.5 months (12-15 months). Our results showed that the total number of harvested lymph nodes in the ICG group was significantly higher than that in the non-ICG group (P < 0.05), and intraoperative blood loss and post-operative hospital stay times in the ICG group were less than those in the non-ICG group (P < 0.05). After 12 months of follow-up, no residual lymph node and local tumor recurrence were found for patients in the ICG group. Four patients in the non-ICG group detected residual lymph nodes at the 3-month visit. Our findings highlighted the importance of ICG fluorescence-guided imaging in LPND because it has unique advantages in improving the number of lymph node dissections, surgical accuracy, and decreasing the residual lymph nodes and local tumor recurrence. In addition, ICG fluorescence guidance technology can effectively shorten the operation time, and it is simple to operate, which is worth popularizing.

Characterization of the complete chloroplast genome of the Solanum tuberosum L. cv. Atlantic (Solanaceae).

Potato (Solanum tuberosum L.), a species of the family Solanaceae, is the fourth most important food crop worldwide. Solanum tuberosum L. cv. Atlantic, a main fried special potato, has a dry matter content of 19%-23% and a starch content of 16.26% in the tuber. In order to support more molecular data for the taxony of S. tuberosum, the complete chloroplast (cp) genome sequence of S. tuberosum L. cv. Atlantic was determined using next-generation sequencing. In leaves, the chloroplast genome accounts for 5.49% of the total genome. The entire cp genome was determined to be 155,296 bp in length. It contained large single-copy (LSC) and small single-copy (SSC) regions of 85,737 and 18,373 bp, respectively, which were separated by a pair of 25,593 bp inverted repeat (IR) regions. The genome contained 132 genes, including 87 protein-coding genes, 37 tRNA genes, and eight rRNA genes. The overall GC content of the genome is 37.9%. A phylogenetic tree reconstructed by 64 chloroplast genomes reveals that S. tuberosum L. cv. Atlantic is most closely related to Solanum tuberosum L. cv. Desiree.

Elevated serum YKL-40 correlates with clinical characteristics in patients with polymyositis or dermatomyositis.

BACKGROUND: Serum YKL-40 has been proved to be a promising biomarker for estimating the disease activity of several autoimmune diseases. However, its utility in polymyositis or dermatomyositis has not been established. The aim of this study was to investigate the utility of YKL-40 in patients with polymyositis/dermatomyositis. METHOD: Patients with definite polymyositis/dermatomyositis who visited the Second People's Hospital of Wuxi between April 2016 and March 2017 were prospectively enrolled. Eighty-seven healthy individuals were set as a control. Serum YKL-40 of all participants was determined using ELISA. The associations between YKL-40 and clinical characteristics of polymyositis/dermatomyositis were analysed using the Student's t-test, Mann-Whitney test and receiver operating characteristic curve analysis. RESULTS: A total of 99 patients with polymyositis/dermatomyositis were enrolled. The patients with polymyositis/dermatomyositis had significantly higher serum YKL-40 concentration. Patients with interstitial lung disease had significantly higher YKL-40 concentration than those without. Serum YKL-40 was positively correlated with myositis disease activity assessment visual analogue scale, C-reactive protein, erythrocyte sedimentation rate and ferritin. The area under receiver operating characteristic curve of YKL-40 for identifying interstitial lung disease was 0.82. CONCLUSIONS: Serum YKL-40 is a useful biomarker for estimating disease activity or severity of polymyositis/dermatomyositis.

[Surgical treatment of superior vena cava syndrome].

OBJECTIVE: To analyze the clinical features, especially surgical treatment of superior vena cava syndrome (SVCS). METHODS: The clinical data of 26 patients with SVCS, 19 males and 7 females, aged 37 (19-63), diagnosed base on the space occupying lesion in mediastinum and complete or incomplete obstruction of SVC and/or innominate vein by imaging examination without evidence of tumor in other parts and without evidence of lymphoma in the mediastinal lesion by pathological examination, who underwent surgical treatment were analyzed, focusing on the clinical presentation, preoperative examination, surgical treatment, pathological diagnosis, and survival. RESULTS: Facial cyanosis and edema, cervical and chest wall varicose veins, headache and dizziness, cough and dyspnea were the most common clinical manifestations. Pre-operative percutaneous needle biopsy guided by CT confirmed the diagnoses of malignant tumor of mediastinum in 6 cases and definite diagnoses failed to be got in the other 20 cases. Resection of the primary lesions combined with artificial blood vessel replacement of SVC was performed. Twenty patients received complete resection, and 6 received only incomplete excision because of extensiveness of lesions. The mean survival time of the former group was 30 months, significantly longer than that of the latter group (11 months, P = 0.0036). The overall 1-year survival rate was 69.2%, and 5-year survival rate was 7.6%. CONCLUSION: Resection procedure is an important factor influencing the prognosis of SVCS.

Red blood cell distribution width and neutrophil to lymphocyte ratio are associated with outcomes of adult subarachnoid haemorrhage patients admitted to intensive care unit.

Background Red blood cell distribution width (RDW) and neutrophil to lymphocyte ratio (NLR) have been reported to be associated with outcomes of acute cerebral infarction. However, their prognostic value in patients with subarachnoid haemorrhage (SAH) remains largely unknown. The aim of this study was to investigate the prognostic value of RDW and NLR in SAH patients. Methods Medical records of adult SAH patients admitted to intensive care unit (ICU) were extracted from Multiparameter Intelligent Monitoring in Intensive Care II (MIMIC II, version 2.6), a publicly accessible ICU database. Prognostic value of RDW and NLR was analysed using logistic regression model, Kaplan-Meier curve analysis and Cox regression model. Results A total of 274 SAH patients were included. Patients died in hospital had significantly higher RDW and NLR. RDW and NLR were significantly associated with hospital death, with adjusted odds ratios of 1.39 (95% CI, 1.06-1.82) and 1.04 (95% CI, 1.00-1.08), respectively. Furthermore, increased RDW and NLR were associated with higher one-year mortality, with an adjusted hazard ratio of 1.20 (95% CI, 1.02-1.41) for per 1% increased RDW and 1.03 (95% CI, 1.00-1.05) for per 1 increased NLR. Conclusion RDW and NLR are useful indices to evaluate the outcomes of ICU admitted patients with SAH.

Wnt10B is critical for the progression of gastric cancer.

The family of Wnt proteins have been implicated in embryogenesis by regulation of cell fate and pattern formation, and also in human carcinogenesis. Wnt10B was previously shown to be involved in breast cancer development. The present study assessed the association of Wnt10B expression in human gastric cancer tissue specimens with clinicopathological data from these patients. Wnt10B expression in the regulation of gastric cancer cell proliferation and migration capacity in vitro was then investigated. The data revealed that Wnt10B mRNA and protein were upregulated in gastric cancer tissue samples and the upregulated Wnt10B mRNA was associated with gastric cancer metastasizing to lymph nodes. Knockdown of Wnt10B expression reduced gastric cancer cell proliferation and migration, as well as expression of a cell proliferation marker Ki67. Knockdown of Wnt10B expression inhibited tumor cell epithelial-mesenchymal transition by upregulation of E-cadherin and downregulation of N-cadherin. In addition, Wnt10B knockdown also suppressed tumor cell stemness by downregulation of octamer-binding transcription factor 4 and Nanog expression. The present data indicated that Wnt10B expression performs an important role in gastric cancer progression in vitro. Therefore, targeting of Wnt10B expression or activity may be investigated as a possible strategy for the control of gastric cancer.

Malignant glomus tumors are extremely rare, and a malignant glomus tumor in the trachea has not been described previously. In this report, we present the first known case of a malignant glomus tumor originating in the trachea.

A preliminary study on the relationship between circulating tumor cells count and clinical features in patients with non-small cell lung cancer.

BACKGROUND: To evaluate the clinical value of circulating tumor cells (CTC) count in peripheral venous blood of patients with non-small cell lung carcinoma (NSCLC). METHODS: A total of 50 NSCLC patients who were diagnosed in Wuxi No. 2 People's Hospital from January 2013 to December 2013 were selected as the NSCLC group, 35 patients with lung benign tumor as the benign group, and 28 healthy subjects as the normal control group. Venous blood samples (3 mL) were collected in all subjects for counting the CTC, and a result of ≥8.7 was judged to be positive. The relationships between the positive rate of CTC and the age, sex, pathological type, and clinical stage of NSCLC were analyzed. RESULTS: CTC count was significantly higher in NSCLC group than in benign group and normal control group. In NSCLC patients, CTC count was not significantly correlated with sex, age, or the pathological type (P>0.05) but was closely related to clinical stage (P<0.01). Among NSCLC patients, CTC count significantly increased along with tumor progression. CONCLUSIONS: CTC count shows certain correlation with the clinical features of NSCLC and thus can, to certain extent, reflect the status of the disease.
