ABSTRACT
Objective To evaluate the value of low-dose spectral CT imaging combined with ASIR recon-struction in differenting peripheral lung cancer from inflammatory mass. Methods We retrospectively analyzed the imaging data of 147 cases with 165 pulmonary nodules or masses underwent enhanced CT scans with spectral imag-ing mode from June 2015 to May 2016. Spectral curves,normalized slope rates,iodine-water concentration were measured on the lesions in arteral phase images. The differences of the spectral characteristic parameters were eval-uated statistically by indepengdent samples t test. Results Among 165 pulmonary nodules or masses,including 68 inflammatory mass and 97 peripheral lung cancer. In the arterial phase,the iodine concentration,water concentra-tion and normalized spectral curves rates of peripheral lung cancer were 10.93 ± 5.12,1033.96 ± 9.74,0.998 ± 0.66,which was obviously higher than those in inflammatory mass in 5.29 ± 0.96,1028.85 ± 9.31,0.620 ± 0.16. There were significant difference between peripheral lung cancer and inflammatory mass(0.000 ,0.008 ,0.001 in P values). Conclusion The iodine concentration,water concentration and normalized spectral curves rates has high value for differential diagnosis of peripheral pung cancer and pneumonia mass in the arterial phase using low-dose spectral CT imaging combined with ASIR reconstruction.
ABSTRACT
Objective To investigate the clinical value of heat shock protein 90α (HSP90α), glutathione S-transferase P1 (GSTP1), ubiquitin specific peptidase 8 (USP8) and chitinase 3-like 1 (CHI3L1) in bronchoalveolar lavage fluid (BALF) and serum for diagnosis and evaluation of the extent of peripheral lung cancer. Methods The levels of HSP90α, GSTP1, USP8 and CHI3L1 of in BALF and serum were measured and compared among 100 patients with peripheral lung cancer (PLC) and 50 patients with benign lung diseases (BLD) by ELISA. The results were compared and analyzed. Results The average content of HSP90α and CHI3L1 in BALF of PLC patients were higher than that in BLD patients (P0.05). The levels of HSP90α and CHI3L1 in BALF of the patients with small nodular lung cancer group (primary focus diameter ≤1cm) and BLD patients showed no significant difference (P>0.05). The levels of GSTP1 and USP8 in BALF and serum of PLC patients and that of BLD patients showed no significant difference (P>0.05). The levels of HSP90α, GSTP1, USP8 and CHI3L1 in BALF and serum showed no significant correlation with other factors, such as the patient's age, pathological classification (adenocarcinoma or squamous carcinoma) and stage of lung cancer (phase to ). The level of CHI3L1 in BALF was correlated to the diameter of the primary foci (P<0.05), while the levels of other lung cancer markers in BALF and serum showed no significant correlation with diameter of primary focus. Conclusion Detection of tumor markers such as HSP90α and CHI3L1 from patients' BALF has a diagnostic value for PLC, and is superior to the examinations of patients' serum specimens. The measurement of HSP90α in BALF shows better clinical value, and it may contribute to the diagnosis of peripheral pulmonary carcinoma.
ABSTRACT
Objective: To investigate the effect of berbamine (BBM) on the induction of apoptosis in human lung cancer cell A549 cells and the activity of TNF-α-JNK signaling pathway. Methods: After the A549 cells being treated with BBM at different concentration, the inhibitory effect of BBM on proliferation was detected by MTT assay. Cell morphological changes were detected by light microscope. Alteration of apoptosis rate of A549 cells was determined by Annexin V/PI double staining. Western blotting was used to detect the activity of apoptosis-related proteins, including Bcl-x, Caspase-3, and PAPR. The expressions of c-jun N-terminal kinase (JNK) and p-JNK were determined by Western blotting. Changes of tumor necrosis factor-alpha (TNF-α) were detected by fluorescent quantitative PCR and ELISA, respectively. Finally, the impacts of BBM on the proliferation and apoptosis of A549 cells were detected in the absence or presence of a JNK inhibitor. Results: BBM significantly inhibited the growth of A549 cells in a dose-dependent manner. The IC50 of 24 h was 9.01 μmol/L. Cells treated with BBM showed the typically morphological characteristics of apoptotic cells. Annexin V/PI double staining test indicated that BBM could induce the apoptosis of A549 cells in a dose-dependent manner. The early apoptotic population of cells treated with 10 μmol/L BBM was 13.8%, which was 5.6 times higher than that of the control. BBM decreased the expression of anti-apoptotic protein Bcl-x and increased the activity of proapoptotic proteins of caspase-3 and PARP. The mRNA and the protein expression levels of TNF-α were significantly increased by BBM treatment. The p-JNK expression was also dramatically up-regulated after BBM treatment. The effects of BBM on the proliferation and apoptosis in A549 cells were significantly reduced when JNK pathway was blocked. Conclusion: BBM could inhibit the growth and induce the apoptosis of A549 cells, and its mechanism may be related to the activated TNF-α-JNK signaling pathway.
ABSTRACT
Objective To investigate the effects of Compound E-Jiao Slurry (CEJS) and Cyclophosphamide (CTX) on the inhibition of Lewis pulmonary carcinoma xenografts. Methods Tumor xenografts models were prepared and randomly divided into six groups by weight, including the control group,CTX, CEJS with the dosages of high, middle and low, with a total of ten mice in each group. The control mice were given normal saline 0.4ml by intragastric administration once daily, with a total of twelve times; The mice of CTX group were given CTX 0.2 ml by intraperitoneal injection every other day, with a total of six times; The mice of CEJS group were given CEJS 0.2 ml and saline 0.2 ml by intragastric administration; The mice of combination therapy group 1 were given CEJS 0.4 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day; The mice of combination therapy group 2 were given CEJS 0.2 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day; The mice of combination therapy group 3 were given CEJS 0.1 ml by intragastric administration once daily, and CTX 0.2 ml by intraperitoneal injection every other day. The weight of tumor xenografts were measured in the experiment,the inhibition rate of tumor xenografts were calculated according to the data after the dissection. Results The combination groups and CTX alone have an inhibition rate of over 50%, and the CEJS group 25.88%. In every experimental group, the weight of tumor showed statistical significance compared with the control (P0.05). Conclusion CEJS can't obviously enhance the sensitivity of tumor xenografts to CTX, but there is a trend for tumor inhibition.
ABSTRACT
Um caso de carcinoma bronquíolo-alveolar difuso do tipo misto foi diagnosticado em um leão-africano (Panthera leo), hospitalizado com sinais de dispnéia e emagrecimento progressivo. Em todos os lobos pulmonares havia múltiplos nódulos esbranquiçados, macios e homogêneos, de 0,2-0,5cm em diâmetro. Histologicamente, os nódulos eram constituídos por células neoplásicas arranjadas em alvéolos e papilas sustentados por moderado estroma fibrovascular, um padrão que lembrava a estrutura pulmonar pré-existente. Na reação pelo ácido periódico de Schiff (PAS) foi observada marcação positiva no citoplasma de numerosas células neoplásicas. Todas as células neoplásicas demonstraram forte e uniforme imunorreatividade citoplasmática para pancitoceratina. A marcação para o fator 1 de transcrição da tireóide (TTF-1) foi observada em focos nos núcleos das células neoplásicas das margens dos nódulos. Nas secções avaliadas para surfactante A, a marcação foi observada em múltiplas áreas focais, tanto no citoplasma como na membrana citoplasmática das células neoplásicas. O diagnóstico de carcinoma bronquíolo-alveolar difuso do tipo misto foi feito com base nos achados histológicos, histoquímicos e imuno-histoquímicos. Essa parece ser a primeira descrição de um neoplasma pulmonar primário maligno em leão-africano.
A case of diffuse bronchioloalveolar carcinoma of the mixed type was diagnosed in the lung of an adult female African lion (Panthera leo) with presenting signs of progressive dyspnea and weight loss. In all pulmonary lobes there were multiple 0.2-0.5cm in diameter soft and homogenous white nodules. Histologically, these nodules consisted of neoplastic cells with an alveolar and papillary disposition, a pattern reminiscent of the preexistent pulmonary structure. The cytoplasms of numerous neoplastic cells were positive in the periodic acid-Schiff (PAS) stain. At immunohistochemistry examination, all neoplastic cells reacted strongly and uniformly to pancytokeratin; focal reactivity for thyroid transcription factor 1 (TTF-1) was observed in the nucleus of neoplastic cells mainly in those at the margins of the nodules. Positive reaction for surfactant A was observed in multifocal areas, both in the cytoplasm and plasma membranes of neoplastic cells. The diagnosis of diffuse bronchioloalveolar carcinoma of the mixed type was made based on histological, histochemistry and immunohistochemistry findings. This seems to be the first report of a primary malignant neoplasm in the lung of the African lion.

Objective To investigate the role of CT in the diagnois of superior vena cava syndrome secondary to pulmonary carcinoma. Method Fifty patients with pulmonary carcinoma resulting in SVCS were confirmed by pathological examinations. Relationship between anatomical distribution and gross type of pulmonary carcinoma and modes of pulmonary carcinoma resulting in SVCS were analyzed retrospectively and statistically. Correlation among obstructive degree of SVC, opening of collateral pathway and swelling of chest wall was analyzed retrospectively and statistically. Results For modes of pulmonary carcinoma resulting in SVCS, direct invasion of pulmonary carcinoma was 7 patients, metastasis of lymph node was 16 patients and both of the two was 27 patients.Modes of pulmonary carcinoma resulting in SVCS were different for different gross types of pulmonary carcinoma in different pulmonary lobes ( x2 = 30.012,P ＜ 0.05). On CT appearances of secondary lesions, cases of simple constitution and opening of collateral pathway, simple swelling of chest wall, both of the two and neither of the two were 14 patients, 12 cases, 15 patients and 9 patients in order on CT. With SVC obstruction at different extent,constitution and opening of collateral pathway and swelling of chest wall were different ( x2= 12.881, P ＜ 0.05).Conclusions SVCS resulted from pulmonary carcinoma can be diagnosed by contrast enhanced CT.
ABSTRACT
Objective To explore the diagnosis for early stage lung cancer with "normal" plain CT scan in order to draw the concern of physician to these patients. Methods We reviewed and analyzed 3 cases of central bronchogenic carcinoma with normal plain CT scan at first visit who were confirmed through fiber bronchoscope examination and PET/CT scan later. Then we compared the values of some diagnostic methods for early-stage central bronchogenic carcinoma. Results Three patients were all males with long smoking history. They came to hospital for cough and bloody sputum. All their plain CT scan showed "no abnormal findings", but their symptom continued. Later, the fiber bronchoscope examination and PET/CT scan strongly suggested that they were suffered from central bronchogenic carcinoma, and then the pathological findings and sputum cytology confirmed the diagnosis. Two patients received lobectomy, and the other one was suggested to accept radiotherapy because of his poor lung function. Conclusions The positive rate of plain CT scan for early-stage central bronchogenic carcinoma is relatively low. Thus, some of these patients lost the chance of surgery and combined therapy. So physicians should pay more attention to these patients with symptoms of persistent bloody sputum or obstructive pneumonia, even if the plain CT scan is negative at first visit. Using PET/CT and fiber bronchoscope examination, physicians can confirm the diagnosis of central bronchogenic carcinoma. So these two methods are important in the diagnosis for early-stage central bronchogenic carcinoma without any abnormal plain CT scan findings.
ABSTRACT
Objective To study CT and MR imaging features of pulmonary carcinoma of mediastinal type.Methods CT and MRI data (including anatomic site,size,shape,margin of the tumors and the relationship between tumors and mediastinum) of 15 patients with pulmonary carcinoma of mediastinal type confirmed by surgery and pathology were analyzed retrospectively.All patients underwent plain CT scans,and 11 of them also underwent contrast-enhanced CT scans,and 3 of them underwent plain MR scans and Gd-DTPA enhanced MR scans.Results On CT and MRI,the single mass was located subpleural of mediastinum with wide base.There were 5 cases of small cell lung carcinoma,8 squamous carcinoma,1 adenocarcinoma and 1 adenosquamous carcinoma.The majority of tumors manifested as ellipse.The tumors were lobulated in 12 and spicular margins in nine.8 tumors located in superior mediastinum,5 in medium mediastinum,2 in infra mediastinum and 12 in the borderline between the anterior mediastinum and medinum mediastinum.The tumors and enlarged lymph nodes of hilar and mediastinum connected closely in 7 cases.The bronchus were stenosed or obstructed by the tumors in 9 cases,and metastatic bone destruction of thoracic cage in 4 cases.Conclusion The pulmonary carcinoma of mediastinal type is easy misdiagnosed,CT and MRI findings in combination with clinical data can improve its diagnostic rate.

ABSTRACT
Objective To investigate the antitumor effects of total glycoside of Cimicifuga dahurica (TGCD) in vivo and in vitro, and further explore its mechanisms. Methods The anti-tumor activity in vitro was determined by MTT assay and the anti-tumor activity in vivo was evaluated using experimental mouse tumor (S180) model and human tumor (A549) xenografts in nude mice. After treatment, A549 cell apoptosis and morphologic change were evaluated by Annexin V/PI flow cytometry and HE staining. Results Inhibitory concentration 50% (IC50) of TGCD on A549, HepG2, HL60, Eca-109 and MDA-MB231 cells were 20.3, 27.1, 21.2, 23.4 and 32.7 ?g/mL respectively. Administration of TGCD (100 or 200 mg/kg) inhibited S180 solid tumor development in mice, the inhibition rates were 42.8% and 54.6% respectively. Administration of TGCD (100 or 200 mg/kg) inhibited A549 tumor growth with a T/C (mean value of treated group/mean value of control group) value of 58.1% and 52.2% respectively. In addition, increased percentage of apoptotic cells induced by TGCD in human A549 nude mice xenografts and the histopathological changes including cell shrinkage and condensation of chromosomes were observed. Conclusion TGCD has demonstrated antitumor bioactivity both in vitro and in vivo, which may be related to its effects of inducing apoptosis activity.

ABSTRACT
The cell killing effects and bystander effects of double suicide gene on pulmonary carcinoma cells were explored. Lung adenocarcinoma cells (A549) were transfected with different titers of adenovirus vector and followed with different concentrations of 5-FC after a recombinant adenovirus vector carrying CD/UPRT gene (Ad-CD/UPRT) was constructed. The cell viability was measured by MTT assay 4 days later. The cell viability was dropped to 30.57 %-8.62 % after 10 MOI of Ad-CD/UPRT transfected and 5-FC (10-1000 μg/mL) administration. Furthermore, Ad-CD/UPRT-infected A549 cells showed a profound neighbor cell killing effect in the same methods. These results suggested that Ad-CD/UPRT/5-FC system can effectively suppress growth of lung adenocarcinoma cells, which may provide a novel and powerful candidate for lung cancer gene therapy strategies.
