Thrombolysis during extended cardiopulmonary resuscitation for autoimmune-related pulmonary embolism / 世界急诊医学杂志（英文）

@#BACKGROUND: Massive pulmonary embolism (MPE) and acute myocardial infarction are the two most common causes of cardiac arrest (CA). At present, lethal hemorrhage makes thrombolytic therapy underused during cardiopulmonary resuscitation, despite the potential benefits for these underlying conditions. Hypercoagulability of the blood in autoimmune disorders (such as autoimmune hemolytic anemia) carries a risk of MPE. It is critical to find out the etiology of CA for timely thrombolytic intervention. METHODS: A 23-year-old woman with a 10-year medical history of autoimmune hemolytic anemia suffered from CA in our emergency intensive care unit. ECG and echocardiogram indicated the possibility of MPE, so fibrinolytic therapy (alteplase) was successful during prolonged resuscitation. RESULTS: Neurological recovery of the patient was generally good, and no fatal bleeding developed. MPE was documented by CT pulmonary angiography. CONCLUSIONS: A medical history of autoimmune disease poses a risk of PE, and the causes of CA (such as this) should be investigated etiologically. A therapy with alteplase may be used early during cardiopulmonary resuscitation once there is presumptive evidence of PE. Clinical trials are needed in this setting to study patients with hypercoagulable states.

Roles of long noncoding RNA in lung cancer / 浙江大学学报·医学版

Long noncoding RNAs are a group of noncoding RNAs with a length more than 200 nucleotides. Recent studies have revealed that long noncoding RNAs play an important role in the development and progression of cancer. Lung cancer is the leading cause of cancer-related death all over the world. In this article, we review the roles of long noncoding RNAs in lung cancer to provide new insights into the diagnosis and treatment of the disease.

Diagnosis value of serum NKX2-1 for primary lung cancer / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To evaluate serum Nkx2-1 (NKX homeobox-1) levels in diagnosis of primary lung cancer.</p><p><b>METHODS</b>The serum NKX2-1 and CEA (carcinoma embryonic antigen) levels were measured in 61 patients with primary lung cancer admitted from May 2009 to December 2010 and 49 healthy individuals served as controls. The receiver operating characteristic curve (ROC) of NKX2-1 in diagnosis for primary lung cancer was analyzed. The value of serum NKX2-1 in diagnosing primary lung cancer was compared with that of CEA by X(2) test and Kappa test.</p><p><b>RESULTS</b>The serum Nkx2-1 levels in lung cancer were significantly higher than those in controls [(1.4206 ±0.1257)ng/ml compared with (0.7646 ±0.0734)ng/ml,P<0.01]. ROC analysis showed the area under the curve of serum NKX2-1 was 0.859. The Kappa value of NKX2-1 was higher than that of CEA (0.586 compared with 0.396,P<0.05). Combination of serum NKX2-1 with CEA improved the Kappa value to 0.704, and also had high sensitivity (83.6%) and specificity (87.0%) for diagnosis of primary lung cancer.</p><p><b>CONCLUSION</b>Serum NKX2-1 protein can be used as a marker for diagnosis of lung cancer, the combination of NKX2-1 with CEA may further improve the diagnostic value.</p>

Urticaria as the initial presentation of early stage bronchioloalveolar carcinoma: a case report / 中华医学杂志(英文版)

Bronchioloalveolar carcinoma is a subtype of the lung adenocarcinoma. Early stage bronchioloalveolar carcinoma is usually asymptomatic, especially in the peripheral lung. Rarely, urticaria has been described occurring with lung cancer, usually small-cell lung cancer, but no case has been reported of the bronchioloalveolar carcinoma yet. We report here a unique and initial urticaria on a patient, lasting for 6 months, who finally was diagnosed as early stage bronchioloalveolar carcinoma (T1aN0M0). After treatment of surgery, the symptom of urticaria disappeared and did not recur. Therefore, we consider that utricaria is a possibly clinical manifestation in early stage bronchioloalveolar carcinoma.

Determination of volatile organic compounds in lung cancer cell lines and lung cancer tissue / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To identify the volatile organic compounds (VOCs) in lung cancer tissue and lung cancer cell lines.</p><p><b>METHODS</b>The lung cancer tissue samples from 18 patients were cultured and 4 lung cell lines (A549, NCI-H446, SK-MES-1, BEAS-2B) were also included in the study. Air samples in the headspace of culture flasks were analyzed for VOCs with solid-phase micro-extraction and gas chromatography-mass spectroscopy technique (SPME-GC/MS).</p><p><b>RESULT</b>Two kinds of VOCs 2-pentadecanone and nonadecane were detected in lung cancer cell lines A549, NCI-H446 and SK-MES-1. The concentration of 2-pentadecanone were (1.382 + or -0.171) X 10(-5)mg/L, (1.681 + or - 0.190) X 10(-4)mg/L and (2.835 + or - 0.401) X 10(-6)mg/L, respectively; the concentrations of nonadecane were (8.382 + or - 0.606 ) X 10(-6)mg/L, (1.845 + or - 0.130) X 10(-5)mg/L and (6.220 + or - 0.362) X 10(-6)mg/L), respectively. The eicosane was detected in A549 and NCI-H446 with the concentration of (8.313 + or - 1.130) X 10(-6)mg/L and (1.020 + or - 0.141) X 10(-5)mg/L), respectively. All the 3 VOCs were not detected in cell line BEAS-2B. The concentrations of 12 VOCs including decane, 2- pentadecanone, nonadecane and eicosane were high in 18 lung cancer tissue samples; the concentrations of 2-pentadecanone were 5.421 X 10(-6)mg/L-3.621 X 10(-5)mg/L,those of nonadecane were 5.805 X 10(-6)mg/L-1.830 X 10(-5)mg/L, those of eicosane were 2.730 X 10(-6)mg/L-2.343 X 10(-5)mg/L. There were no differences of VOCs levels among patients with different cancer differentiation (P>0.05). The concentration of eicosane in the non-squamous carcinoma was higher than that in squamous carcinoma, the same results were confirmed in the lung cancer cell lines.</p><p><b>CONCLUSION</b>This study has identified VOCs produced by lung cancer tissue, which may support to use breath test as a complementary noninvasive diagnostic method for lung cancer.</p>

Comparison of low-molecular-weight-heparin and unfractionated heparin for acute PTE / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

<p><b>OBJECTIVE</b>Acute pulmonary thromboembolism (PTE) is a serious high mortality pulmonary vascular disease whose effective treatment decreases morbidity and mortality. To determine if low-molecular-weight-heparin (LMWH) is clinically as efficient and safe as unfractionated heparin (UH) in patients with diagnosis of acute non-massive PTE, our study compares the efficacy, adverse effects and costs of LMWH and UH.</p><p><b>METHODS</b>One hundred and fourteen patients with non-massive acute PTE were randomly divided into LMWH (nadroparin calcium) and UH groups. Oxygenation index, D-dimer, fibrinogen (FG), lung ventilation/perfusion (V/Q) scan and computed tomography pulmonary angiography (CTPA) were observed before anticoagulation and on day 14 after anticoagulation.</p><p><b>RESULTS</b>In both groups, the ABG (arterial blood gas) analysis showed PaO(2) and PaCO(2) were elevated, P(A-a)O(2) was decreased and oxygenation index (PaO(2)/FIO(2)) was elevated, D-dimer and fibrinogen were decreased, lung V/Q and CTPA showed embolized segments reduced (P<0.05). Hemorrhage and thrombocytopenia occurred in 3.5% of the LMWH group. Hemorrhage occurred in 5.3% and thrombocytopenia occurred in 7.0% of the UH group. The average cost in the LMWH group was RMB 1218.60 Yuan and RMB 1541.40 Yuan in the UH group.</p><p><b>CONCLUSION</b>LMWH and UH are equally effective for treatment of non-massive acute PTE, but LMWH may have a lower prevalence of complications and is less expensive.</p>

Deletion of P16 gene exon 2 in bronchofibroscopic brush-off cells of human lung carcinoma / 浙江大学学报·医学版

OBJECTIVE: To analyze the relationship between deletion of P16 gene exon 2 and lung cancer and to evaluate the possibility of detecting P16 gene exon 2 deletion in brush-off cell instead of resected lung cancer mass. METHODS: P16 gene exon 2 deletion in bronchofibroscopic brush-off cells of lesion side and corresponding normal side was detected through PCR-electrophoresis-Image. Image value of P16 Vs beta-actin <0.6 was considered as P16 gene exon 2 deletion. RESULTS: The rate of P16 gene exon 2 deletion in normal side was 0 (0/19), whereas in lesion side was 35.5%(11/31), there is a significant statistical difference (P<0.01). In SCLC (small -cell lung carcinoma) samples, the rate of P16 gene exon 2 deletion was 0(0/7). whereas in NSCLC (non-small cell lung carcinoma) samples, that was 50%(11/12)(P<0.05). CONCLUSION: P16 gene exon 2 deletion might be related to the oncogenesis and development of lung carcinoma, especially NSCLC. Brush-off cell specimens may replace surgical specimens in Detecting P16 gene exon 2 deletion.
