Active earth pressure acting on retaining wall considering anisotropic seepage effect

Journal of Mountain Science 2017年第6期14卷 1202-1211页

This paper presents a general solution for active earth pressure acting on a vertical retaining wall with a drainage system along the soil-structure interface. The backfill has a horizontal surface and is composed of cohesionless and fully saturated sand with anisotropic permeability along the vertical and horizontal directions. The extremely unfavourable seepage flow on the back of the retaining wall due to heavy rainfall or other causes will dramatically increase the active earth pressure acting on the retaining walls, increasing the probability of instability. In this paper, an analytical solution to the laplace differential governing equation is presented for seepage problems considering anisotropic permeability based on Fourier series expansion method. A good correlation is observed between this and the seepage forces along a planar surface generated via finite element analysis. The active earth pressure is calculated using Coulomb's earth pressure theory based on the calculated pore water pressures. The obtained solutions can be degenerated into Coulomb's formula when no seepage exists in the backfill. A parametric study on the influence of the degree of anisotropy in seepage flow on the distribution of active earth pressure behind the wall is conducted by varying ratios of permeability coefficients in the vertical and horizontal directions,showing that anisotropic seepage flow has a prominent impact on active earth pressure distribution. Other factors such as effective internal friction angle of soils and soil/wall friction conditions are also considered.

The full-length cDNA sequence of prophenoloxidase was obtained through RACE technology. The complete cDNA sequence is 3 72.-bp long, containing an open reading frame （ORF） of 1 881 bp, a 154-bp 5′-untranslated region, and a 1 686- bp 3′-untranslated region with three potential functional poly（A） signals （AATAAA）. The molecular mass of the deduced amino acid sequence （62. aa） was 72.3 kDa with an estimatedpI of 5.88. It contained putative copper-binding sites （copper A： 131, 135, 167 and copper B： 301,305, 341）, and a tentative complement-like motif （GCGWPDHl）. Eight potential N-linked glycosylation sites were predicted to be present in P. clarkii prophenoloxidase. Similar to those in other arthropod prophenoloxidases reported so far, no signal peptide was detected in the crayfish prophenoloxidase. The phylogenetic trees confirmed that P. clarkii prophenoloxidase was most closely related to that of freshwater crayfish P. leniusculus and more closely related to other crustacean prophenoloxidases from shrimp, prawn, and lobster than to the insect prophenoloxidases. Besides, two putative introns were found in this sequence of genomic DNA.

Dear Editor,Metastasis is the cause of most fatalities in cancer patients and remains the phenomenon poorly understood mechanistically. Deciphering of the regulatory networks underlying the cancer cell metastasis is urgently needed. Nucleolar protein 7 (NOl7) has been reported to function as a tumor suppressor in cervical cancer.1 Our current study reveals a novel tumor-promoting capacity of NOl7 in melanoma. We first detected that NOl7 expression is upregulated in metastatic melanoma as compared with its expression at the primary site through isobaric tag for relative and absolute quantitation proteomic screening, further confirming this finding with the analysis of NOl7 protein and messenger RNA (mRNA) levels (Supplementary Fig. S1). Importantly, NOl7 expression increased with the disease progression from benign nevus to primary melanoma and further to metastatic melanoma (Fig. 1a and Supplementary Fig. S1d). Previous studies have shown that melanoma is commonly associated with the amplification of the chromosome region 6p, particularly 6p2.–2., where the NOl7 gene resides, and that this region frequently undergoes heterozygous loss in cervical cancer.2.It might therefore be predicted that NOl7 exhibits a different expression pattern and plays different roles in melanoma and cervical cancer.

Xi-Tong Zhang Xu-Dong chen Ke Xu department of Interventional Radiology Shenzhen People’s Hospital the Second Affiliated Hospital of Jinan University department of Radiology The First Affiliated Hospital of China Medical University Key laboratory of Diagnostic Imaging and Interventional Radiology of liaoning Province The First Affiliated Hospital of China Medical University

AIM To investigate 30-year treatment outcomes associated with Budd-Chiari syndrome(BCS) at a tertiary hospital in *** A total of 2.6 patients diagnosed with primary BCS at our tertiary hospital between November 1983 and September 2.13 were followed and retrospectively studied. Cumulative survival rates and cumulative mortality rates of major causes were calculated by Kaplan-Meier analysis, and the independent predictors of survival were identified using a Cox regression model. RESUlTS Thirty-four patients were untreated; however, 2.2.patients were treated by medicine, surgery, or interventional radiology. Forty-four patients were lost to follow-up; however, 2.2.patients were followed, 67 of whom died. The symptom remission rates of treated and untreated patients were 81.1%(107/132. and 46.2.(6/13), respectively(P = 0.009). The cumulative 1-, 5-, 10-, 2.-, and 30-year survival rates of the treated patients were 93.5%, 81.6%, 75.2., 64.7%, and 58.2., respectively; however, the 1-, 5-, 10-, 2.-, and 30-year survival rates of the untreated patients were 70.8%, 70.8%, 53.1%, 0%, and unavailable, respectively(P = 0.007). Independent predictors of survival for treated patients were gastroesophageal variceal bleeding(HR = 3.043, 95%CI: 1.363-6.791, P = 0.007) and restenosis(HR = 4.610, 95%CI: 1.916-11.091, P = 0.001). The cumulative 1-, 5-, 10-, 2.-, and 30-year mortality rates for hepatocellular carcinoma were 0%, 2.6%, 3.5%, 8%, and 17.4%, *** long-term survival is satisfactory for treated Chinese patients with BCS. Hepatocellular carcinoma is a chronic complication and should be monitored with long-term follow-up.
