Author＇s reply

To the Editor： We are pleased to respond to the letter of Zarogiannis and his colleagues for their interest in our study, emphasizing the role of human visceral pleura in pleura fluid turnover. We definitely agree to Zarogiannis and colleagues＇ comments that the absence of many cuboidal cells in the visceral pleura does not favor the existence of visceral lymphatic stomata. However, any medical basic theory must be tested clinically, or used to interpret clinical phenomena well. The current model of pleural fluid turnover is hard to explain more frequently those with pleural effusion found in patients with merely left heart failure than those with merely right heart failure.     

Endovascular stent-grafts for acute and chronic type B aortic dissection: comparison of clinical outcomes

Background Endovascular stent-graff treatment has emerged as an alternative for patients with type B aortic dissection （AD）, either at acute or chronic phase, in selected patients. This study aimed to investigate the results of endovascular stent-graft repair for acute and chronic type BAD. Methods From May 2002 to July 2007, 67 patients with type BAD were treated by endovascular stent-graft placement. There were 32 patients in the acute phase （AAD group） and 35 patients in the chronic phase （CAD group）. The patients were followed up from 1 to 65 months （average, 17_＋16 months）. The immediate and follow-up clinical outcomes were documented and compared between the 2 groups. Results Placement of endovascular stent-grafts across the primary entry tears was technically successful in all 67 patients. Compared with patients in the CAD group, those in the AAD group had higher percentages of pleural effusion （15.6% vs 0, P=-0.02） and visceral/leg ischemia （21.9% vs 2.9%, P=0.02）. Procedure related complications, including endoleak and post-implantation syndrome occurred more frequently in AAD group than in CAD group （21.9% vs 2.9% and 31.3% vs 8.6%, respectively; P=0.02 and P=0.02）. Kaplan-Meier analysis showed no significant difference in survival rate at 4 years between the 2 groups （86.4% vs 92.3%, P=0.42 by Log-rank test）. But the 4-year event-free survival rate was higher in patients with chronic dissection than in patients with acute dissection （96.2% vs 73.9%; P=0.02 by Log-rank test）. Conclusions Endovascular repair with stent-graff was safe and effective for the treatment of both acute and chronic type BAD. However, both immediate and long term major complications occurred more frequently in patients with acute dissection than in those with chronic dissection.     

Long-term results of prophylactic cranial irradiation for limited-stage small-cell lung cancer in complete remission

Background Brain metastasis is one of the most important causes of treatment failure in patients with small cell lung cancer (SCLC). This study was conducted to evaluate the effects of prophylactic cranial irradiation (PCI) on survival and brain metastases for patients with limited stage small cell lung cancer in complete remission.Methods Fifty one patients with limited stage SCLC in complete remission after chemoradiotherapy were randomly divided into PCI group (n=26) and control group (n=25). Patients in the PCI group received PCI at a dose of 25.2 to 30.6 Gy in 1.8 to 2.0 Gy per fraction. The Kaplan-Meier method and Log rank test were used to analyse and compare survival rates, and χ2 test was used to compare the incidences of cranial metastases in two groups. Results There was no significant difference in clinical characteristics of patients such as age, sex, effect of treatment before PCI between the two groups. The incidence of brain metastases was 3.8% in the PCI group in contrast to 32.0% in the control group (χ2=5.15, P=0.02). The 1, 3, 5-year survival rates were 84.6%, 42.3%, 34.6% respectively in the PCI group and 72.0%, 32.0%, 24.0% respectively in the control group, with no difference between the two groups (χ2=2.25, P=0.13). No serious sequelae were observed in patients receiving PCI. Conclusion For patients with limited stage SCLC responding completely to chemotherapy plus radiotherapy, PCI can decrease the incidence of brain metastases and improve survival rate.     

Surgical treatment of IIIb-T4 lung cancer invading left atrium and great vessels

Background IIIb-T4 non-small cell lung cancer （NSCLC） is commonly considered a contraindication to surgery, although chemo-radiotherapy also achieves a poor survival rate. We reviewed our experience with T4 NSCLC patients who underwent surgery to explore the indications and prognostic factors of surgical treatment of lung cancer invading the left atrium and great vessels. Methods We investigated a cohort of 105 patients, 79 men and 26 women, who underwent surgery from May 1996 to July 2008. Their pathological staging was T4No-2M0. The median age was 59 years, ranging from 36 to 75 years. Patients were grouped based on invading sites： tumors invading the left atrium （LA group）, tumors invading the superior vena cava （SVC group）, and tumors invading the intrapericardial pulmonary artery （PA group）. Patients were further characterized based upon the type of operation, complete resection and incomplete resection groups, and on the lymph node pathological status, No, N1 and N2 groups. We calculated the overall five-year survival rate. Results All patients received resection of primary lesions, with partial resection of the left atrium in the LA group （n=-25）, angioplasty of superior vena cava in the SVC group （n=-23） and intrapericardial ligation of the pulmonary artery in the PA group （n=57）. Complete resection was possible in 77 patients （73.3%）. The overall survival rate of the 105 patients was 41.0% at 5 years; 36.0% for the LA group, 34.8% for the SVC group and 45.6% for the PA group. Pathological N status significantly influenced the overall 5-year survival rate; 61.5% for No, 51.1% for the N1 and 11.8% for the N2 groups （N2 group versus No group, P 〈0.0001, N2 versus N1 group, P〈0.0001）. Surgical resection also influenced survival; 49.4% for the complete resection group and 17.9% for the incomplete resection group （P 〈0.0001）. Cox regression analysis demonstrated that pathological N status was a significant independent predictor of prognosis. Conclusions Pathological N status is a significant independent predictor for survival of patients with IIIb-T4 lung cancer invading the left atrium and great vessels. The completeness of resection has a significant influence on the overall 5-year survival rate. Surgery for T4 lung cancer may be effective in patients without mediastinal lymph node involvement.

Objective To investigate the clinical effect of esomeprazole combined with magnesium aluminum carbonate in patients with gastric ulcer. Methods A total of 106 patients with gastric ulcer who were treated in our hospital from September to September 20, 2017 were enrolled in this study. They were randomly divided into two groups, 53 patients in each group. The control group received oral esomeprazole. Study group On this basis, magnesium aluminocarbonate was added for treatment, and the total clinical effective rate and ulcer diameter of the two groups were compared. Results The total effective rate of the study group was 92.45% higher than that of the control group(77.36%)(P 0.05). The diameter of the study group was(2.21±1.83) mm. The study group was significantly lower than the control group. The difference was statistically significant(P 0.05).Conclusion The combination of esomeprazole and aluminum magnesium carbonate in gastric ulcer disease can promote the healing of gastric ulcer and improve the clinical efficacy.     

Expression of soluble triggering receptor expression on myeloid cells-1 in pleural effusion

Background Triggering receptors expressed on myeloid cells （TREM） proteins are a family of cell surface receptors expressed broadly by cells of the myeloid lineage. The aim of this study was to investigate the clinical significance of soluble TREM-1 （sTREM-1） in pleural effusions, and to determine the effects of pneumonia on pleural sTREM-1 concentrations. Methods Pleural fluid was collected from 109 patients who presented to the respiratory institute （35 with malignant pleural effusion, 31 with tuberculous pleural effusion, 21 with bacterial pleural effusion, and 22 with transudate）. The concentrations of sTREM-1, tumor necrosis factor-a （TNF-a） and interleukin-113 （IL-113） were determined in effusion and serum samples by enzyme linked immunosorbent assay （ELISA）. Results The concentrations of sTREM-1 in bacterial pleural effusion were significantly higher than those in malignant, tuberculous, and transudative groups （all P 〈0.001）. An sTREM-1 cutoff value of 768.1 ng/L had a sensitivity of 86% and a specificity of 93%. Pleural sTREM-1 levels were positively correlated with levels of TNF-a and IL-113. Patients with complicating bacterial pneumonia did not have elevated concentration of sTREM-1 in pleural effusion when compared with patients without pneumonia. Conclusions Determination of pleural sTREM-1 may improve the ability of clinicians to differentiate pleural effusion patients of bacterial origin from those with other etiologies. The occurrence of bacterial pneumonia did not affect pleural sTREM-1 concentrations.

Clinical Value of Tumor Markers for Determining Cause of Pleural Effusion

Background:

It is often challenging to distinguish tuberculous pleural effusion (TPE) from malignant pleural effusion (MPE); thoracoscopy is among the techniques with the highest diagnostic ability in this regard. However, such invasive examinations cannot be performed on the elderly, or on those in poor physical condition. The aim of this study was to explore the differential diagnostic value of carbohydrate antigen 125 (CA125), carbohydrate antigen 199 (CA199), carcinoembryonic antigen (CEA), neuron-specific enolase (NSE), and squamous cell carcinoma (SCC) associated antigen in patients with TPE and MPE.

Methods:

Using electrochemiluminescence, we measured the concentration of tumor markers (TMs) in the pleural effusion and serum of patients with TPE (n = 35) and MPE (n = 95). We used receiver operating characteristic (ROC) curve analysis to evaluate the TMs and differentiate between TPE and MPE.

Results:

The cut-off values for each TM in serum were: CA125, 151.55 U/ml; CA199, 9.88 U/ml; CEA, 3.50 ng/ml; NSE, 13.27 ng/ml; and SCC, 0.85 ng/ml. Those in pleural fluid were: CA125, 644.30 U/ml; CA199, 12.08 U/ml; CEA, 3.35 ng/ml; NSE, 9.71 ng/ml; and SCC, 1.35 ng/ml. The cut-off values for the ratio of pleural fluid concentration to serum concentration (P/S ratio) of each TM were: CA125, 5.93; CA199, 0.80; CEA, 1.47; NSE, 0.76; and SCC, 0.90. The P/S ratio showed the highest specificity in the case of CEA (97.14%). ROC curve analysis revealed that, for all TMs, the area under the curve in pleural fluid (0.95) was significantly different from that in serum (0.85; P < 0.001).

Conclusions:

TMs in TPE differ significantly from those in MPE, especially when detected in pleural fluid. The combined detection of TMs can improve diagnostic sensitivity.
