Objective To evaluate the role of transbrochial needle aspiration (TBNA) in the diagnosis of patients with enlarged mediastinal and/or hilar lymph node. Methods Patients with mediastinal and/or hilar lymphoadenopathy proven by CT scan were eligible for TBNA as reported. All specimens were directly and instantly smeared for pathological examination. Results From June 1 2004 to December 31 2007, 164 patients were examined: including 80 lung cancers, 69 lung bengin diseases, 2 other malignancy tumor, and 13 without definite diagnosis. Total 260 lymph nodes were punctured. TBNA procedures were successfully carried out in 445/463(96.1%). Sensitivity of TBNA was 82. 5 % (66/80) in patients who had been proven to suffer from bronchogenic carcinoma. There were 25 patients that diagnosis of lung cancer was pathologically determined by TBNA only. A total of 122 lymph nodes in the 80 lung cancer patients were aspirated by TBNA with a positive rate of 65. 6% (80/122). Severe complications were rare except small amount of bleeding at the TBNA site (100/164, 61.0%). From June 1 2006 to December 31 2007, lymph node tissues able to make histology diagnosis were yield in 73.5% (64/87) patients. Through histology pathology, the sensitivities of TBNA were 53. 3% (8/15) for sarcoidosis and 78.6% (33/42) for lung cancer. Conclusion TBNA is quite safe and helpful in diagnosis and staging of bronchogenic carcinoma, and in diagnosis of benign lung diseases.

Objective Type 2 diabetes increases the risk of colorectal cancer and reduces the survival rate of the patients. Therefore, analyzing the characteristics of colorectal cancer in patients with type 2 diabetes may help to develop precise medical measures and to improve the prognosis of patients. Methods The pathological characteristics of 123 colorectal cancer cases with or without type 2 diabetes were analyzed. In addition, PCR and pyrosequencing method were used to test the common gene mutation status of colorectal cancer, including KRAS( codons 12, 13, 61, and 146) , BRAF( codon 600) , and PIK3CA ( exons 9 and 20) , in order to investigate the molecular characteristics of colorectal cancer in diabetic patients which may provide some clues to clinical decision. Results The mean age and body mass index of patients with diabetes were higher than those of patients without diabetes, but there was no difference in the location, the degree of cell differentiation and the grade of colorectal cancer between these 2 groups. The rate of PIK3CA mutation in patients with type 2 diabetes mellitus, especially in patients with long term type 2 diabetes was significantly higher than that in patients without diabetes (28.6%vs 10.3%, P<0.05). There was no significant difference between the two groups in common BRAF and KRAS mutation sites. Conclusion Diabetes does not alter the clinical pathological characteristics of colorectal cancer, but long course type 2 diabetes increases PIK3CA mutation rate. Therefore, using medicine targeting PIK3CA gene mutation may help to improve the prognosis of patients.

Objective:
Pulmonary metastatic angiosarcoma is a rare, fatal disease that often presents as diffuse alveolar hemorrhage(DAH). In this report, clinical characteristics of pulmonary metastatic angiosarcoma were retrospectively reviewed.
Methods:
A total of 9 patients with angiosarcoma who presented as DAH were enrolled. Clinical data included age, gender, symptoms, smoking status, physical exam findings, pulmonary function tests, and radiology.
Results:
All patients were male with median age 41 years(range, 22 to 57 years). The most common symptom was hemoptysis(9/9). Other symptoms included dyspnea (5/9), cough(3/9), chest pain(3/9), fever(2/9,) and edema of the lower extremity and oliguria(4/9).The common misdiagnoses were tuberculosis(4/9), vasculitis(3/9) and other infection(1/9). Chest computed tomography showed bilateral,random distributed different-sized nodules(9/9),as well as ground-glass areas (9/9).The hearts, mainly right atrium, were the most common primary locations(7/9).Cardiac mass was the first manifestation in five patients by echocardiography(5/8).Two atrial masses were identified by computer tomography pulmonary angiography and magnetic resonance imaging respectively. Transbronchial lung biopsy failed to find malignancy. Computer tomography guided transthoracic needle biopsy was difficult to perform in most patients. Eight patients were diagnosed by surgical biopsy, either by lung biopsy(4/8) or cardiac biopsy(4/8).The median survival period was only 3 months after surgery.
Conclusion
Metastatic pulmonary angiosarcoma should be considered in patients with DAH and multiple glass ground opacity and nodules on chest CT. Careful cardiologic monitoring is necessary. Surgical biopsy is reliable for diagnosis.

Objective:To analyze the differences in clinical characteristics, microbiologic distributions, in vitro susceptibility, treatment and outcomes between elderly and young/middle-aged patients with nocardiosis.Methods:A total of 27 patients diagnosed with nocardiosis by bacteria culture and gene sequencing in our hospital from May 2007 to September 2011 were included.Patients were separated into two groups according to their ages.Clinical characteristics, laboratory tests, treatment and prognosis were compared between the two groups.Results:Of the 27 patients, 11 were male and 16 were female, with a median age of 50 years(range, 20-84 years old)and a median course of 3.0 months(range, 0.5-60.0 months). There were 6 cases in the elderly group and 21 cases in the non-elderly group.The common underlying diseases were chronic pulmonary disease(4/6, 66.7%), metabolic disease(2/6, 33.3%)and connective tissue disease(2/6, 33.3%)in the elderly group, and connective tissue disease(9/21, 42.9%), chronic pulmonary disease(6/21, 28.6%)and hematological disease(2/21, 9.5%)in the non-elderly group.Results of laboratory tests revealed that white blood cell counts were normal or elevated, lymphocyte percentages decreased and neutrophils percentages were elevated in both two groups.All patients in the elderly group had pulmonary infection, while 71.4%(15/21)had pulmonary infection and 28.6%(6/21)had disseminated infection in the non-elderly group.The proportion of patients with pulmonary consolidation on CT was higher in the elderly patients than in the non-elderly patients(100% vs.42.9%, P=0.02). The detection rates of N. cyriacigeorgica, N. farcinica, N. abscessus, N. Africana and N. wallacei were 50.0%(3/6), 16.7%(1/6), 16.7%(1/6), 16.7%(1/6)and 0%(0/6)in the elderly group and 23.8%(5/21), 42.9%(9/21), 42.9%(9/21), 4.8%(1/21)and 14.3%(3/21)in the non-elderly group, respectively.The mortality rate was 16.7% in the elderly patients and 28.6% in the non-elderly patients.The 5-year survival rates in both two groups were 100%. Conclusions:Elderly patients with nocardiosis often have underlying pulmonary disease with a long disease course. N. farcinica is the main observed strain.Multiple nodules and plaques and consolidation are common on CT.Multi-drug combinations are recommended in treatment.Concomitant fungal or other bacterial infections are factors for poor prognosis.The long-term prognosis is good in patients with nocardiosis.

The increasing use of immunocheckpoint inhibitors in tumors has brought new hope of survival to patients with advanced tumors. However, the immune system activated by immunocheckpoint inhibitors, mainly activated T-cell immunity, may attack normal tissues and organs of the human body and lead to a variety of adverse effects. In the lung, they could induce checkpoint inhibitor associated pneumonitis (CIP). CIP is different from known pulmonary interstitial pneumonitis, and had a potentially fatal risk if it was not being properly treated. We will summarize the characteristics of CIP and give our advice on how to manage immunocheckpoint inhibitor associated pneumonitis.
