Abstract
The shift from rice-wheat rotation (RWR) to greenhouse vegetable soils has been widely practiced in China. Several studies have discussed the changes in soil properties with land-use changes, but few studies have sought to address the differences in soil pore properties, especially for fields based on long-term organic fertilization under greenhouse vegetable system from RWR fields. This study uses the X-ray computed tomography (CT) scanning and statistical analysis to compare the long-term effects of the conversion of organic greenhouse vegetable fields (over one year, nine years, and fourteen years) from RWR fields on the soil macropore structure as well as the influencing factors from samples obtained in Nanjing, Jiangsu, China, using the surface soil layer and triplicate samples. The results demonstrated that the macropore structure became more complex and stable, with a higher connectivity, fractal dimension (FD) and a lower degree of anisotropy (DA), as the greenhouse vegetable planting time increased. The total topsoil macroporosity increased considerably, but the rate of increase gradually decelerated with time. The transmission pores (round pores ranging from 50 to 500μm) increased with time, but the biopores (>2000μm) clearly decreased after nine years of use as greenhouse vegetable fields. Soil organic matter (OM) has a significant relationship with the soil pore structure characteristics, especially for the transmission pores. In addition, organic fertilization on the topsoil had a short-term effect on the pores, but the effect stabilized and had a weak influence on the pores over longer periods. These results suggested that organic fertilization was conducive for controlling soil degradation regarding it physical quality for water and oxygen availability in the short term.

Abstract
Background A few retrospective studies have indicated that neoadjuvant chemotherapy (NAC) in breast cancer may change biomarker profiles of the primary tumor. Little is known about the status of HER-2 gene of the synchronous nodal metastases when that of the residual tumor undergoes negative conversion in a neoadjuvant setting. Case presentation We describe a female patient with left breast cancer (T2N2M0) who underwent negative conversion of HER-2 in the primary tumor instead of the synchronous nodal lesions after NAC. Core needle biopsy showed invasive ductal carcinoma with HER2 immunohistochemistry (IHC) (2+) and amplified HER-2 gene determined by fluorescence in situ hybridization (FISH). Then, the patient underwent 4 cycles of anthracycline- and taxane-based NAC and subsequent left modified radical mastectomy. Postoperative pathology showed invasive ductal carcinoma involving 4 of 12 surgically excised axillary lymph nodes with HER2 IHC (1+) and FISH negative (HER2 gene not amplified) in the residual tumor of the breast specimen. Due to the negative genic switch of HER2 after NAC, the patient rejected to accept trastuzumab. Under the patient’s consent, the synchronous nodal lesions were further investigated and showed HER2 IHC(−) but FISH positive (HER-2 gene amplified). Therefore, the patient agreed to accept adjuvant trastuzumab treatment every 3 weeks for 1 year. Conclusions We propose further assessment of HER2 gene in the synchronous nodal metastases, especially when negative genic switch of HER-2 occurs in the primary tumor after NAC in order to tailor the systemic regimens for breast cancer patients.

Abstract
Diffuse large B-cell lymphoma (DLBCL) is the most common non-Hodgkin lymphoma, whose main prognostic factor is closely related to germinal center B-cell-like subtype (GCB- DLBCL) or activated B-cell-like type (non-GCB-DLBCL). The most common type of primary central nervous system lymphoma is diffuse large B-cell type with poor prognosis and the reason is unclear. This study aims to stratify primary central nervous system diffuse large B-cell lymphoma (PCNS-DLBCL) according to the cell-of-origin (COO) and to investigate the multiple proteins expression of C-MYC, BCL-6, BCL-2, TP53, further to elucidate the reason why primary central nervous system diffuse large B-cell lymphoma possesses a poor clinical outcome as well. Nineteen cases of primary central nervous system DLBCL were stratified according to immunostaining algorithms of Hans, Choi and Meyer (Tally) and we investigated the multiple proteins expression of C-MYC, BCL-6, BCL-2, TP53. The Epstein-Barr virus and Borna disease virus infection were also detected. Among nineteen cases, most (15-17 cases) were assigned to the activated B-cell-like subtype, highly expression of C-MYC (15 cases, 78.9%), BCL-2 (10 cases, 52.6%), BCL-6 (15 cases, 78.9%). Unfortunately, two cases were positive for PD-L1 while PD-L2 was not expressed in any case. Two cases infected with BDV but no one infected with EBV. In conclusion, most primary central nervous system DLBCLs show an activated B-cell-like subtype characteristic and have multiple expressions of C-MYC, BCL-2, BCL-6 protein, these features might be significant factor to predict the outcome and guide treatment of PCNS-DLBCLs.

Abstract
This study aimed to investigate the effect of sevoflurane on serum levels of interleukin (IL)-6 and IL-8 in patients who underwent cardiopulmonary bypass (CPB). The strength of the association between sevoflurane treatment and serum level of IL-6 and IL-8 was determined in patients who underwent CPB by summary standard mean differences (SMDs); 95% confidence interval (CI) was used. In total, seven case-control studies showed decreased IL-6 and IL-8 levels in sevoflurane-treated patients than in controls (IL-6: SMD = 1.56, 95%CI: 0.95-2.17, P < 0.001; IL-8: SMD = 1.63, 95%CI: 0.30-2.96, P < 0.001, respectively). Further, IL-6 and IL-8 levels were significantly higher in sevoflurane-treated patients than in sevoflurane-pretreated patients (IL-6 post vs pre: SMD = 2.17, 95%CI: 1.40-2.95, P < 0.001; IL-8 post vs pre: SMD = 4.01, 95%CI: 2.80-5.21, P < 0.001, respectively). CPB-stratified analysis showed significant decrease in IL-6 and IL-8 levels in sevoflurane-treated patients than in controls, irrespective of the time after CPB surgery (P < 0.05). Moreover, sevoflurane-pretreated patients under the <12-h subgroup showed decreased IL-6 levels (P = 0.698), while all other subgroups showed decreased IL-8 levels (P < 0.05). Further, subgroup analysis by different dose of sevoflurane showed decreased IL-6 and IL-8 levels in subgroups administered with a dose of <2 and ≥ 2% sevoflurane under the case vs control and pre- vs post-treatment of sevoflurane models. Serum IL-6 and IL-8 levels were significantly lower in sevoflurane-treated patients who underwent CPB, suggesting sevoflurane pretreatment to be more beneficial than post-treatment.

Abstract
As a highly conserved nuclear protein, death domain-associated protein (Daxx) plays an important role in transcriptional control, carcinogenesis, and resistance to virus infection and so on. In order to further investigate the mechanism of Daxx, the yeast two-hybrid technique was used to screen the intra-cellular proteins interacting with Daxx. And 13 positive colonies and three proteins interacting with Daxx were obtained. One of the candidate proteins was identified as ferritin, heavy polypeptide 1(FTH1). The interaction between Daxx and FTH1 was further supported by GST pull-down and co-immunoprecipitation respectively. Then Daxx was determined to induce apoptosis and FTH1 can inhibit Daxx-mediated apoptosis. Besides, it is found that Daxx mediated apoptosis through the Fas-Daxx-ASK1-JNK1 signaling pathway, while FTH1 can inhibit the activation of JNK signaling pathway. We present evidence to demonstrate the FTH1 and Daxx are able to participate in apoptosis pathway through JNK signal molecule and FTH1 can inhibit this pathway.
