    Abstract As reported in many research, LncRNA CTBP1 divergent transcript (CTBP1-AS2) remarkably affects the progression of several tumors. However, the precise role and function of CTBP1-AS2 in hepatocellular carcinoma (HCC) remained unknown. We found that CTBP1-AS2 expressions were increased in HCC samples and cells. After treatment with microwave ablation (MWA), CTBP1-AS2 was distinctly up-regulated in residual HCC tissues compared with HCC samples. CTBP1-AS2 was upregulated under the induction of the nuclear transcription factor SP1. As revealed by the clinical assays, high CTBP1-AS2 expression usually related to lymph node metastasis, clinical stage and weaker prognosis specific to HCC patients. Functionally, CTBP1-AS2 knockdown suppressed HCC cells in terms of the proliferation, migration, invasion, chemotherapy resistance as well as EMT progress, but promoted apoptosis. Mechanistically, CTBP1-AS2 was a sponge of miR-195-5p for elevating CEP55 expression, a target of miR-195-5p, and thereby exhibited its oncogenic roles in HCC progression. Overall, an emerging regulatory mechanism of SP1/CTBP1-AS2/miR-195-5p/CEP55 axis was reported in the paper, which possibly served as a new therapeutic HCC treatment target.

    Abstract Background: In China, it has been well recognized that some female patients with esophageal squamous cell carcinoma (ESCC) have different overall survival (OS) time, even with the same tumor-node-metastasis (TNM) stage, challenging the prognostic value of the TNM system alone. An effective predictive model is needed to accurately evaluate the prognosis of female ESCC patients.
    Aim: To construct a novel prognostic model with clinical and reproductive data for Chinese female patients with ESCC, and to assess the incremental prognostic value of the full model compared with the clinical model and TNM stage.
    Methods: A new prognostic nomogram incorporating clinical and reproductive features was constructed based on univariatie and Cox proportional hazards survival analysis from a training cohort (
    Results: A clinical-reproductive model including incidence area, age, tumor differentiation, lymph node metastasis (N) stage, estrogen receptor alpha (ESR1) and beta (ESR2) expression, menopausal age, and pregnancy number was constructed to predict OS in female ESCC patients. Compared to the clinical model and TNM stage, the time-dependent ROC and C-index of the clinical-reproductive model showed a good discriminative ability for predicting 1-, 3-, and 5-years OS in the primary training, internal and external validation sets. Based on the optimal cut-off value of total prognostic scores, patients were classified into high- and low-risk groups with significantly different OS. The estrogen response was significantly associated with p53 and apoptosis pathways in esophageal cancer.
    Conclusion: The clinical-reproductive prognostic nomogram has an incremental prognostic value compared with the clinical model and TNM stage in predicting OS in Chinese female ESCC patients.

    Abstract Background: Primary small cell carcinoma of the esophagus (PSCE) is a highly invasive malignant tumor with a poor prognosis compared with esophageal squamous cell carcinoma. Due to the limited samples size and the short follow-up time, there are few reports on elucidating the prognosis of PSCE, especially on the establishment and validation of a survival prediction nomogram model covering general information, pathological factors and specific biological proteins of PSCE patients.
    Aim: To establish an effective nomogram to predict the overall survival (OS) probability for PSCE patients in China.
    Methods: The nomogram was based on a retrospective study of 256 PSCE patients. Univariate analysis and multivariate Cox proportional hazards regression analysis were used to examine the prognostic factors associated with PSCE, and establish the model for predicting 1-, 3-, and 5-year OS based on the Akaike information criterion. Discrimination and validation were assessed by the concordance index (C-index) and calibration curve and decision curve analysis (DCA). Histology type, age, tumor invasion depth, lymph node invasion, detectable metastasis, chromogranin A, and neuronal cell adhesion molecule 56 were integrated into the model.
    Results: The C-index was prognostically superior to the 7
    Conclusion: Our nomogram can be used to predict the survival probability of PSCE patients, which can help clinicians to make individualized survival predictions.

    Abstract Background: Developing new strategies to reduce the output power of microwave (MW) ablation while keeping anti-tumor effect are highly desirable for the simultaneous achievement of effective tumor killing and avoidance of complications. We find that mild MW irradiation can significantly increase intracellular Ca
    Results: The as-made NaCl-DOX@PLGA nanoplatform selectively elevates the temperature of tumor tissue distributed with nanoparticles under low-output MW, which further prompts the release of DOX from the PLGA nanoparticles and tumor cellular uptake of DOX. More importantly, its synergistic effect not only combines thermal ablation and chemotherapy, but also obviously increases the intracellular Ca
    Conclusions: This work provides a biocompatible and biodegradable nanoplatform with triple functions to realize the effective tumor killing in unlethal temperature. Those findings provide reliable solution to solve the bottleneck problem bothering clinics about the balance of thermal efficiency and normal tissue protection.

    Abstract Aim: To determine the effect of different Roux-en-Y gastric bypass procedures in gastric carcinoma patients with type 2 diabetes mellitus.
    Methods: A retrospective analysis of the clinical data of 54 patients with gastric cancer and type 2 diabetes mellitus treated in the Department of General Surgery from January 2006 to June 2013 was conducted. The patients underwent gastrectomy using different Roux-en-Y gastric bypass procedures (traditional, n = 26; modified, n = 28). Fasting plasma glucose (FPG), two hour postprandial blood glucose (2 h PBG) and hemoglobin A1c (HbA1c) were analyzed before surgery (0 mo) and 1, 3 and 6 mo after surgery.
    Results: FPG and 2 h PBG levels were significantly decreased 1 mo after surgery in the traditional Roux-en-Y gastric bypass group (FPG 7.5 ± 1.3 vs 10.7 ± 1.2, P < 0.05) (2 h PBG 10.2 ± 1.8 vs 13.8 ± 3.2, P < 0.05). FPG and 2 h PBG levels were significantly decreased after surgery in the modified Roux-en-Y gastric bypass group (FPG 6.9 ± 1.2 vs 10.5 ± 1.1, 6.5 ± 1.3 vs 10.5 ± 1.1, 6.4 ± 1.2 vs 10.5 ± 1.1, P < 0.05) (2 h PBG 9.9 ± 2.2 vs 14.1 ± 2.9, 9.2 ± 2.4 vs 14.1 ± 2.9, 8.9 ± 2.6 vs 14.1 ± 2.9, P < 0.05). Compared with the levels before surgery, HbA1c levels were significantly decreased 3 and 6 mo after surgery (7.2 ± 1.1 vs 10.5 ± 1.1, 5.5 ± 1.1 vs 10.5 ± 1.1, P < 0.05). Significant differences between the two groups regarding FPG, 2 h PBG and HbA1c concentration were observed 3 and 6 mo after surgery (FPG 10.1 ± 1.5 vs 6.5 ± 1.3, 10.3 ± 1.4 vs 6.4 ± 1.2, P < 0.05) (2 h PBG 13.1 ± 2.8 vs 9.2 ± 2.4, 13.6 ± 3.1 vs 8.9 ± 2.6, P < 0.05) (HbA1c 10.1 ± 1.4 vs 7.2 ± 1.1, 10.5 ± 1.3 vs 5.5 ± 1.1, P < 0.05).
    Conclusion: Modified Roux-en-Y gastric bypass can improve glucose metabolism in type 2 diabetic patients with gastric cancer.

    Abstract N-Doped nanocages with thin-walled graphitic shells (∼1.2 nm) were synthesized by removing the ferrous cores of Fe@C nanoparticles. The Fe@C nanopores were prepared by floating catalytic pyrolysis with the N atoms being in situ doped in their graphitic shells. Due to the thin-walled graphitic shells of the nanocages, the fast distribution of the electrolyte and ions was achieved and the prepared nanocage-based anode of lithium-ion batteries showed excellent performance: a high reversible specific capacity (after 50 cycles; 760 mA h g−1 at 0.5 A g−1) and a remarkable rate capability (after 40 cycles; 250 mA h g−1 at 10 A g−1).

    Abstract By using crystal field theory, the optical spectra, zero field splitting and g factors have been calculated. The defect structure for V(3+) in ZnO crystal has been studied by using crystal field theory and first-principle calculations. The results show that, the V(3+) ions do not occupy the exact Zn(2+) site, but displaced along C(3) axis.
