Background: Wiskott-Aldrich syndrome verprolin-homologous (WAVE) 3 has been reported to be implicated in various malignant tumors, but its role in hepatocellular carcinoma (HCC) remains elusive. The aim of this study was to investigate the effect of WAVE3 on the behaviors of HCC cells and to evaluate its clinical impact. Materials and methods: A total of 120 paired of HCC and adjacent non-cancerous tissues were used to detect expression pattern of WAVE3 by immunohistochemistry. Then, the associations of WAVE3 expression with clinicopathologic characteristics and patients' prognosis were examined. The roles of WAVE3 in migration and invasion of HCC cell line HepG2 were also evaluated in vitro. Results: Positive immunostaining of WAVE3 protein was predominantly observed in the cytoplasm of HCC cells. Compared to adjacent non-cancerous tissues, the expression levels of WAVE3 protein were significantly upregulated in HCC tissues (P< 0.001). Additionally, high WAVE3 expression was significantly associated with advanced tumor stage (P= 0.008) and positive distant metastasis (P= 0.001). Then, high WAVE3 expression correlated significantly with poor prognosis, and WAVE3 status was identified as an independent significant prognostic factor. Moreover, small interfering RNA targeting WAVE3 was used to inhibit the expression of WAVE3 in HepG2 cells. We found that suppression of WAVE3 could inhibit migration and invasion of HepG2 cells. Conclusion: Our clinical study have characterized WAVE3 as biomarker for HCC progression and metastasis, and more importantly, have identified it as an independent prognostic marker for HCC patients. Our data also indicated that WAVE3 is pivotal in controlling oncogenic phenotypes of human HCC cells. © 2014 Elsevier Masson SAS.

Background and Objective: Inflammation is deemed to play critical roles in tumor progression and metastasis, and an increased neutrophil-lymphocyte ratio (NLR) has been reported to correlate with poor survivals in various malignancies. However, association between NLR elevation and survival outcome in patients with colorectal liver metastasis (CRLM) remains controversial. The aim of this study was to investigate the prognostic significance of elevated NLR in CRLM. Methods: The meta-analysis was conducted in adherence to the MOOSE guidelines. PubMed, Embase, Cochrane Library, Web of Science and the Chinese SinoMed were systematically searched to identify eligible studies from the initiation of the databases to May, 2016. Overall survival (OS) and recurrence free survival (RFS) were pooled by using hazard ratio (HR) with corresponding 95% confidence interval (CI). Correlation between NLR values and clinicopathological features was synthesized by using odds ratio (OR) with corresponding 95% CI. Results: A total of 1685 patients from 8 studies (9 cohorts) were analyzed, consisting 347 (20.59%) in high pretreatment NLR value group and 1338 (79.41%) in low pretreatment NLR value one. The results demonstrated that elevated pretreatment NLR was significantly related to poor OS (HR 2.17, 95% CI 1.82-2.58) and RFS (HR 1.96, 95% CI 1.64-2.35) in patients with CRLM. Conclusion: The result of this systematic review and meta-analysis indicated that an elevated pretreatment NLR was closely correlated with poor long-term survival (OS and RFS) in CRLM patients. NLR can be routinely monitored and serve as a useful and cost-effective marker with strong prognostic significance in patients with CRLM. © 2016 Tang et al.

Objective To analyze the factors influencing brachial-ankle pulse wave velocity (baPWV) and to establish a logit model for predicting baPWV. Methods The data of 4 159 cases who underwent health examination from 2010 to 2014 in our hospital were retrospectively analyzed. The parameters included gender, age, systolic blood pressure, diastolic blood pressure, pulse, fasting glucose, triglyceride, cholesterol, alanine aminotransferase, glutamyl transpeptidase and cholesterol, low density lipoprotein (LDL), high density lipoprotein (HDL), and uric acid. Logistic regression was used to explore the influencing factors of baPWV, and a regression model was established to predict baPWV and it was evaluated. Results Univariate analysis showed that, except for HDL, all the other parameters above were significantly different between normal baPWV group and abnormal baPWV group (P<0.05). Multivariable analysis yielded the following logit model: logit (p)=-17.888+0.001×uric acid 0.004×alanine aminotransferase 0.105×fasting glucose 0.023×pulse 0.032×diastolic blood pressure 0.061×systolic blood pressure 0.092×age 0.411×sex, which showed a correct predicting rate of 79.6% for baPWV in health examination population, with the ROC area being 0.869 (95%CI:0.859-0.879). Conclusion The baPWV values can be influenced by gender, age, systolic blood pressure, diastolic blood pressure, pulse, fasting blood glucose, alanine aminotransferase and uric acid levels, and logit model may serve as a satisfactory model for these types of study. © 2015, Academic Journal of Second Military Medical University.

PurposeTo describe the characteristic ophthalmic phenotypes of a large Chinese family with familial amyloid polyneuropathy due to a missense mutation in transthyretin (TTR) (c.307 C>G).MethodsTwenty-seven individuals (12 affected, 15 unaffected) from a five-generation Chinese family underwent general medical examination and comprehensive ophthalmic examination, including best correct visual acuity, intraocular pressure measurements, Schirmer test, slitlamp examination, fundoscopy, and ocular ultrasonography. Histological examination of vitreous biopsies using Congo red staining and immunohistochemistry was performed. Cardiovascular magnetic resonance (CMR), electrocardiogram, and echocardiogram were used to evaluate cardiac amyloidosis. Electromyography was used to evaluate nerve function. All four exons of TTR were amplified by PCR, sequenced using a Bigdye terminator v3.1 cycle sequencing kit and analyzed on an ABI 3700XL Genetic Analyzer.ResultsAll 12 affected individuals in the family had ocular manifestations, including severe vitreous opacities, secondary glaucoma, xerophthalmia, dyscoria, and attenuated retinal arteries. Congo red staining demonstrated amyloid deposits in the vitreous, and immunohistochemical staining confirmed the deposition of TTR proteins in the vitreous. Twelve individuals had polyneuropathy, and electromyography detected functional damage in peripheral nerves. One individual was diagnosed with cardiac amyloidosis by CMR. Direct sequencing revealed the heterozygous missense mutation in TTR (c.307 C>G p.Gly83Arg) in all 12 affected individuals. The mutation co-segregated with the disease phenotype and was absent in 100 normal controls.ConclusionsVitreous opacity is very common in patients with the TTR Gly83Arg mutation; other clinical characteristics associated with the mutation include polyneuropathy and cardiac amyloidosis. © 2014 Macmillan Publishers Limited All rights reserved.

OBJECTIVE: To compare cricothyroid membrane puncture directed tracheostomy (CMPDT) with conventional surgical tracheostomy (ST) and cricothyroidotomy (CT) and to evaluate the feasibility, efficacy and safety of this novel technique.METHODS: 15 minipigs were divided randomly into 3 groups, 5 in each. After general anesthesia, CMPDT, ST and CT were performed respectively according to the established techniques when SPO₂reached 80% (T0). Procedure duration, ECG and arterial blood gas results were recorded. Complications were recorded and scored according to an established score scale by an observer blinded to the grouping.RESULTS: Airway was successfully established in all animals (15/15). ECG monitor showed T-wave decreased and Q-T shortened after seasing of oxygen supply and both recovered rapidly to normal levels after reoxygenation. There were no significant differences between 3 groups in HR, BP, SPO2, SaO₂, PaO₂, PaCO₂and pH at pre-apnea, T0 or post-operation, but with significant intragroup variation in the parameters before and after operation. The time for CMPDT, ST and CT was (174 ± 34) s, (619 ± 128) s and (86 ± 12) s respectively. Three of 5 minipigs in ST group experienced hypotension due to longer time of hypoxia. 1 and one had minor bleeding and stoma infection after surgery. One of 5 animals in CT group had minor laryngeal cartilage injury leading to difficult decannulation, postoperative fiber bronchoscopy showed no subglottic stenosis. The complication scores were 13, 9, and 3 for ST, CT and CMPDT, respectively.CONCLUSIONS: All 3 methods can provide with effective airway access with no significant differences in ventilation effect, however CMPDT has short recovery time for SpO2 and other vital signs with the lowest complication score. The animal experiment suggests that CMPDT is a fast, safe and effective surgical technique for emergency airway.
