The diagnostic accuracy of blood-pressure-toheight-ratios (BPHRs) in 716 Nigerian children was studied, using standard protocols. Systolic BPHR (SBPHR) and diastolic BPHR (DBPHR) had diagnostic accuracies ranging from 0.934 to 1.000, irrespective of sex and age. Optimal thresholds of SBPHR/DBPHR are provided, and their sensitivities and specificities all exceeded 80%. BPHR is a simple, sensitive and specific tool for the diagnosis of hypertension in this population. © The Author [2012]. Published by Oxford University Press. All rights reserved.

The aim of this study was to evaluate the relationship between body adiposity index (BAI) and pregnancy-induced hypertension (PIH) in third-trimester pregnant women. This study included 126 women in the third trimester of pregnancy. All participants completed anthropometric measurements and ultrasonic testing. The formula of BAI was hip circumference (cm)/height (m)−18. The frequency of PIH were significantly higher in the upper tertile group (31.0%) than in the low tertile group (7.1%) and the middle tertile group (4.8%) (P<0.01). The area under curve values for the accuracy of BAI in identifying PIH were 0.784. The optimal threshold of BAI for identifying PIH was 36.0. The sensitivity was 72.2% and the specificity was 85.1%. BAI was correlated with PIH. The performance of BAI for identifying third-trimester pregnant women with PIH was moderately accurate. Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.

MicroRNAs are involved in tumor initiation and progression by regulating oncogenes and tumor suppressor genes. Here we found that miR-495 are lower in clinical ESCC tissues than in adjacent non-tumor tissues. Moreover, the lower miR-495 expression correlated with increased lymph node metastasis (LNM), invasion and TNM stage. miR-495 overexpression predicted a favorable outcome in ESCC patients. miR- 495 targeted a site in the 3'-UTR of Akt1, and miR-495 levels correlated inversely with Akt1 protein levels in ESCC tissue samples. Overexpression of miR-495 suppressed cell proliferation, blocked G1/S phase transition, and decreased migration and invasion by two ESCC cell lines in vitro and in vivo. Restoration of Akt1 protein levels in miR-495- overexpressing ESCC cells attenuated the inhibitory effects of miR-495. In addition, miR-495 suppressed cell cycle transition and the EMT signaling pathway through targeting Akt1, thereby inhibiting ESCC cell proliferation, migration, and invasion. Our results suggest that miR-495 may act as a tumor suppressor by targeting Akt1 in ESCC.

Lipopolysaccharide (LPS) can activate alveolar epithelial cells (AECs) and induce inflammatory injury. Toll-like receptor-4 (TLR-4) is integrally involved in LPS signaling and has a requisite role in the activation of NF-κB. NF-κB is a key intercellular signaling event that mediates cell inflammatory responses. The aim of the study is to investigate in an in vitro model the inflammatory responses of AECs induced by LPS and the probable mechanism underlined the observed inflammatory responses. So cytokines of ICAM-1, TNF-α and IL-8 secreted by LPS-activated AECs were observed. And the initial signal molecule (the expression of TLR-4 mRNA) and the key intracellular steps (the activation of NF-κB) were studied in detail. The study was performed on A549 cells (Human lung adenocarcinoma cell line). A549 cells were divided into two groups: control, and LPS interference group. Proinflammatory cytokines ICAM-1, TNF-α and IL-8 were detected by ELISA or radioimmunological methods. The expression of TLR-4 mRNA was detected by real time PCR. The activation of NF-κB was detected by Western blot (proteins of I-κBα and NF-κB p65). Compared with control group, ICAM-1 and TNF-α of LPS-stimulated group were significantly higher and peaked after 2h before gradually declining at 6 and 12 h; IL-8 was higher after 2 h, which continued up to 12 h. The expression of TLR-4 mRNA of LPS group was significantly higher and peaked after 2 h and gradually declining at 6 and 12 h. Meanwhile, NF-κB was activated after 0.5, 2, 6 and 12 h indicated by the significant degradation of IκB-α and the significant release of NF-κB P65 and its subsequent translocation into the nucleus approximately synchronized. Taken together, the results demonstrate that LPS can induce AECs inflammatory injury via activating TLR-4 and subsequently activating NF-κB.

Background: There is a lack of studies comparing stapled suturing and hand-sewn suturing in the surgeries of gastrointestinal tumors based on the clinical practice of Chinese surgeons.Methods: Data were retrospectively collected from 499 patients who underwent surgery to remove gastrointestinal tumors from January 2008 to December 2009. The patients were divided into two groups according to the method of digestive tract reconstruction: 296 patients received stapled suturing and 203 patients received hand-sewn suturing. The operation time, postoperative hospital stay, postoperative recovery and complications of the patients were evaluated and compared between the two groups.Results: The stapling procedure took shorter operative time compared to the hand-sewn procedure for gastric carcinoma, colorectal cancer and esophageal carcinoma (P < 0.05). There was no significant difference between the two groups in postoperative hospital stay (P > 0.05). Patients receiving stapled suturing also showed shorter recovery for gastric cancer, colorectal cancer, and shorter time to recovery of normal gastrocolorectal motility compared with patients in the hand-sewn group (P < 0.05). However, there was no difference between the two groups in terms of normal time to commencing liquid diet for esophageal cancer patients (P > 0.05). We also found that the stapled procedure showed a lower incidence of anastomotic leakage, anastomotic hemorrhage and stump leakage in treating colorectal cancer or gastric carcinoma compared with the hand-sewn procedure (P < 0.05).Conclusions: Application of the stapler in treating gastrointestinal tumors demonstrated better effects on patients in terms of surgical operation time, recovery time to normal functions, and occurrence of complications compared to hand-sewn anastomosis, especially in gastric carcinoma and colorectal cancer. © 2014 Liu et al.; licensee BioMed Central Ltd.

This study aimed to evaluate the prognostic significance of lymph node ratio (LNR) by establishing a hypothetical tumor-ratio-metastasis (TRM) staging system in patients with esophageal squamous cell carcinoma (ESCC). The records of 387 ESCC patients receiving curative esophagectomy were retrospectively investigated. The optimal cut-point for LNR was assessed via the best cut-off approach. Potential prognostic parameters were identified through univariate and multivariate analyses. A novel LNR-based TRM stage was proposed. The prognostic discriminatory ability and prediction accuracy of each system were determined using hazard ratio (HR), Akaike information criterion (AIC), concordance index (C-index), and area under the receiver operating characteristic curve (AUC). The optimal cut-points of LNR were set at 0, 0~0.2, 0.2~0.4, and 0.4~1.0. Multivariate Cox analysis indicated that the LNR category was an independent risk factor of overall survival (P<0.001). The calibration curves for the probability of 3- and 5-year survival showed good consistency between nomogram prediction and actual observation. The LNR category and TRM stage yielded a larger HR, a smaller AIC, a larger C-index, and a larger AUC than the N category and TNM stage did. In summary, the proposed LNR category was superior to the conventional N category in predicting the prognosis of ESCC patients.

The present study evaluated the simplicity and accuracy of a new modified blood pressure-to-height ratio (MBPHR3) in identifying hypertension among Han children aged 7-12 years. In 2011, anthropometric measurements were collected as part of a cross-sectional population-based study of 1352 Han children aged 7-12 years. Receiver operating characteristic curve analyses were performed to assess the accuracy of the modified systolic blood pressure-to-height ratio (MSBPHR3) and the modified diastolic blood pressure-to-height ratio (MDBPHR3) as diagnostic tests for the detection of elevated SBP and DBP, respectively. The accuracies of MSBPHR3 and MDBPHR3 (as assessed by the area under the curve) in identifying elevated SBP and DBP were greater than 0.85 (0.974-0.995). When the MBPHR3 was used to identify hypertensive children, the sensitivity was 100% in boys and 100% in girls. The specificity was 93.8% in boys and 97.1% in girls. In conclusion, the MBPHR3 is a simple, accurate and non-age-dependent index for the screening of hypertension in Han children.

This study evaluated the accuracy of modified blood pressure-to-height ratio (MBPHR) for identifying hypertension in Han children aged 7-12 years.In 2011, anthropometric measurements were assessed in a cross-sectional population-based study of 1352 Han children aged 7-12 years. Elevated blood pressure was defined according to the 2004 National High Blood Pressure Education Program Working Group definition (as gold standard). The following equations for MBPHR were used: modified systolic blood pressure to height ratio(MSBPHR)=SBP(mmHg)/(height(cm)+7(13-age(years))), modified diastolic blood pressure to height ratio (MDBPHR)=DBP(mmHg)/(height(cm)+7(13-age(years))). Receiver operating characteristic curve analyses were performed to assess the accuracy of MSBPHR and MDBPHR as diagnostic tests for elevated SBP and DBP, respectively.The accuracy of MSBPHR and MDBPHR (assessed by area under the curve) for identifying elevated SBP and DBP were over 0.85 (0.953-1.000). When elevated blood pressure was defined by MBPHR (age-dependent cut-off point), the sensitivities were 99.1% in boys and 97.0% in girls and the specificities were 89.0% in boys and 92.3% in girls. When elevated blood pressure was defined by MBPHR (non-age-dependent cut-off point), the sensitivities were 96.4% in boys and 99.2% in girls and the specificities were 81.2% in boys and 75.5% in girls.MBPHR is an accurate index for screening hypertension in children, but is not superior to BPHR. Compared with age-dependent BPHR cutoff points, non-age-dependent MBPHR cut-off point is simple but increase the proportion of reexamination.

The mechanisms underlying oxaliplatin (OXA) resistance in colon cancer cells are not fully understood. MicroRNAs (miRNAs) play important roles in tumorigenesis and drug resistance. However, the relationship between miRNA and OXA resistance in colon cancer cells has not been previously explored. In this study, we utilized microRNA microarray analysis and real-time PCR to verify that miR-93, miR-191, miR-137, miR-181 and miR-491-3p were significantly down-regulated and that miR-96, miR-21, miR-22, miR-15b and miR-92 were up-regulated in both HCT-15/OXA and SW480/OXA cell lines. Blocking miR-137 caused a significant inhibition of OXA-induced cytotoxicity, therefore, miR-137 was chosen for further research. An in vitro cell viability assay showed that knockdown of miR-137 in HCT-15 and SW480 cells caused a marked inhibition of OXA-induced cytotoxicity. Moreover, we found that miR-137 was involved in repression of YBX1 expression through targeting its 3-untranslated region. Furthermore, down-regulation of miR-137 conferred OXA resistance in parental cells, while over-expression of miR-137 sensitized resistant cells to OXA, which was partly rescued by YBX1 siRNA. The results of this study may aid the development of therapeutic strategies to overcome colon cancer cell resistance to OXA.

Diagnostic significance of interleukin 6 (IL-6) for lung cancer patients with radiation pneumonitis (RP) was examined within various studies, but yielded conflicting results. Thus, this meta-analysis was performed to demonstrate correlations between serum IL-6 levels and RP in lung cancer patients.Electronic databases updated to March 2014 were searched to find relevant studies. Relevant literatures were searched under the PubMed, Embase, Web of Science, Cochrane Library, CISCOM, CINAHL, Google Scholar, CBM and CNKI databases. STATA statistical software (Version 12.0, Stata Corporation, and College Station, TX) Standardized mean difference (SMD), and its corresponding 95% confidence intervals (CIs) were used for this meta-analysis. In addition, nine cohort studies met the inclusion criteria and involved a total of 137 RP patients and 295 non-RP patients.The results of combined SMD suggested that serum IL-6 levels in RP patients was significantly higher than in non-RP patients before radiotherapy. While, there was a significant difference in serum IL-6 levels of RP patients between before and after radiotherapy, we observed no difference in serum IL-6 levels between RP patients and non-RP patients after radiotherapy. Ethnicity-stratified analyses indicated that increased serum IL-6 levels were related to the risk of RP in lung cancer patients among Caucasians, but not detected among Asians (all P > 0.05).The main finding of our meta-analysis reveals that increased serum IL-6 levels may contribute to the incidence of RP in lung cancer patients, especially among Caucasians.
