Nomogram For The Prediction Of Malignancy In Small (8-20 mm) Indeterminate Solid Solitary Pulmonary Nodules In Chinese Populations.

Purpose: This study aimed to develop and validate a nomogram for predicting the malignancy of small (8-20 mm) solid indeterminate solitary pulmonary nodules (SPNs) in a Chinese population by using routine clinical and computed tomography data.

Methods: The prediction model was developed using a retrospective cohort that comprised 493 consecutive patients with small indeterminate SPNs who were treated between December 2012 and December 2016. The model was independently validated using a second retrospective cohort comprising 216 consecutive patients treated between January 2017 and May 2018.

The Correlation of Visfatin and Its Gene Polymorphism with Non-Small Cell Lung Cancer.

To investigate the protein expression of visfatin and its gene polymorphism in non-small cell lung cancer (NSCLC) patients. The plasma level of visfatin was detected by enzyme-linked immunosorbent assay, and the genotypes rs59744560, rs9770242, and rs61330082 in the visfatin gene were detected by gene sequencing. This study revealed that plasma levels of visfatin in NSCLC patients were significantly higher than the levels in healthy people ( < 0.

MicroRNA-370 inhibits the growth and metastasis of lung cancer by down-regulating epidermal growth factor receptor expression.

Abnormal microRNA-370 (miR-370) expression has been frequently reported in several types of cancers, including lung cancer. However, the role and molecular mechanisms of miR-370 in regulating the growth and metastasis of lung cancer have not been clarified. Here, we show higher levels of epidermal growth factor receptor (EGFR), but lower levels of miR-370 expression in most human lung cancer cells and non-tumor cells.

Acquired resistance to HSP90 inhibitor 17-AAG and increased metastatic potential are associated with MUC1 expression in colon carcinoma cells.

Heat shock protein 90 (HSP90) is a molecular chaperone required for the stability and function of many proteins. The chaperoning of oncoproteins by HSP90 enhances the survival, growth, and invasive potential of cancer cells. HSP90 inhibitors are promising new anticancer agents, in which the benzoquinone ansamycin 17-allylamino-17-demethoxygeldanamycin (17-AAG) is currently in clinical evaluation.

An orally administered DNA vaccine targeting vascular endothelial growth factor receptor-3 inhibits lung carcinoma growth.

Lung cancer is the leading cause of mortality and 5-year survival rate is very low worldwide. Recent studies show that vascular endothelial growth factor receptor-3 (VEGFR-3) signaling pathway contributes to lung cancer progression. So we hypothesize that an oral DNA vaccine that targets VEGFR-3 carried by attenuated Salmonella enterica serovar typhimurium strain SL3261 has impacts on lung cancer progression.

Moderating effects and maintenance of lung cancer cellular immune functions by CIK cell therapy.

Aims: To study the CIK cell treatment effects on regulation of cellular immune function disorders in patients with lung cancer, and to analyze the time characteristics.

Methods: Cellular immune function was assessed by FCM, and patients with functional disorders were randomly divided into two groups, one given CIK cell therapy within 18 months (5 courses) and the other the controls, which were followed up for 1 year with cellular immune functions tested once a month.

Results: There were 5 types of cellular immunity, 4 of which are disorders; after CIK treatment, the improvement rate of the 4 groups were 79.

[Expression of transcription factor SOX4 and its clinical significance in female lung cancer patients in Xuanwei area, Yunnan Province].

Objective: To investigate the expression of transcription factor SOX4 in lung cancer tissues of female patients in Xuanwei area, Yunnan Province, and explore its correlation with clinicopathological characteristics and prognosis of the female patients.

Methods: Real-time PCR was applied on lung cancer specimens and their corresponding normal lung tissues from 96 female cases of Xuanwei area to assess the expression of SOX4 mRNA. Immunohistochemical staining was performed to investigate the SOX4 protein expression, and further to elucidate its correlation with clinicopathological characteristics and prognosis.

[Evaluation of effects of quality scale for removable partial dentures in clinical application].

Purpose: To evaluate the effects of quality scale for removable partial dentures (RPD)in clinical application.

Methods: Quality scale for removable partial dentures was designed. Twelve items were devised for visual survey and try-in in base, artificial teeth, clasp, rest, connector and adjustment.

Thyroid transcription factor 1 represses the expression of Ki-67 and induces apoptosis in non-small cell lung cancer.

The thyroid transcription factor 1 (TTF-1) gene is associated with the differentiation of lung epithelial cells and has been reported to be an independent prognostic factor for lung adenocarcinoma patients. The aim of the present study was to detect the expression of TTF-1 in human lung cancer cell lines and to evaluate the association of overexpressed TTF-1 with Ki-67 and apoptosis in the A549 cell line. We also investigated the expression of TTF-1 and Ki-67 in Xuanwei lung adenocarcinoma.

Characterization of two human lung adenocarcinoma cell lines by reciprocal chromosome painting.

Lung cancer is a leading cause of cancer death worldwide. Some lung cancer patients correlate with a gas of radon besides smoking. To search for common chromosomal aberrations in lung cancer cell lines established from patients induced by different factors, a combined approach of chromosome sorting, forward and reverse chromosome painting was used to characterize karyotypes of two lung adenocarcinoma cell lines: A549 and GLC-82 with the latter line derived from a patient who has suffered long-term exposure to environmental radon gas pollution.

Orally administered DNA vaccine delivery by attenuated Salmonella typhimurium targeting fetal liver kinase 1 inhibits murine Lewis lung carcinoma growth and metastasis.

The vascular endothelial growth factor (VEGF) receptor 2 (VEGFR-2), also called fetal liver kinase 1 (FLK1) in mice and kinase insert domain receptor (KDR) in humans, is an endothelial cell specific receptor tyrosine kinase that mediates lung cancer angiogenesis. We hypothesized that an active immunotherapy approach targeting FLK1 may inhibit lung cancer growth and metastasis. To test this hypothesis, we evaluated whether immune responses to FLK1 could be elicited in mice by immunization with an orally administered DNA vaccine encoding the extracellular domain (ECD) of FLK1 (pcDNA3.

A comparative study of gene vaccines encoding different extracellular domains of the vascular endothelial growth factor receptor 2 in the mouse model of colon adenocarcinoma CT-26.

Aims: To compare the immunogenicity and anti-tumor effects of gene vaccines encoding domains 1-4 with full length of extracellular region of VEGFR2.

Results: Both DNA vaccines decreased VEGF levels and rose specific antibodies; the lymphocyte subsets of vaccinated mice maintained high; tumor latency period and survival time of immunized mice were prolonged; tumor size, weight, MVD and liver metastases were significantly less than the control groups.

Methods: Mouse model of CT-26 adenocarcinoma of colon were treated with orally immunized gene vaccine encoding extracellular 1-4 and full length of VEGFR2 respectively.
