The Value of Serum Dickkopf 1 Protein for Early Diagnosis of Esophageal Cancer

Abstract：　Objective　To explore the value of serum Dickkopf-related protein 1 （DKK1）for the early diagnosis of esophageal cancer， and provide theoretical evidence for the diagnosis and treatment of esophageal cancer.　Methods　A total of 145 patients who were admitted to the Affiliated Hospital of Jiangnan University between October 2009 and April 2011 were included in this study and divided into four groups. There were 72 patients in the esophageal cancer group　（54 males and 18 females with their median age of 60.4 years），13 patients in the precancerosis group （9 males and 4　females with their median age of 58.6 years），30 patients in the benign esophageal lesion group （23 males and 7 females with their median age of 56.4 years），and 30 healthy people in the volunteer group （19 males and 11 females with their median age of 58.6 years）. Serum DKK1 protein concentration was measured by enzyme linked immunosorbent assay （ELISA）. Receiver operating characteristics （ROC） curve was drawn to determine the cutoff level with optimal diagnostic accuracy.　Results Serum DKK1 protein levels were significantly higher in the esophageal cancer group and precancerosis group than those in the volunteer group and benign esophageal lesion group ［（37.5±2.8） μg/L， （19.7±2.7） μg/L vs. （5.7±0.8） μg/L， （6.5±0.8） μg/L，t=47.391， P＜0.05］. There was no statistical difference in serum DKK1 protein level between the　volunteer group and benign esophageal lesion group ［（6.5±0.8） μg/L vs. （5.7±0.8） μg/L， t=4.215，P=0.374］. When the level of serum DKK1 protein was 13.4 μg/L， the diagnostic sensitivity and specificity of esophageal cancer were 74.1% and 96.7%， respectively.　Conclusion　Overexpression of serum DKK1 protein could be related to the pathogenesis and progression　of esophageal cancer. DKK1 protein may be a potential serologic biomarker for the early diagnosis of esophageal cancer.

Pulse Oximetry Screening for Congenital Heart Disease in Asymptomatic Children：A Systematic Review and Meta-Analysis

Objective To investigate the accuracy of pulse oximetry screening for congenital heart disease （CHD） in asymptomatic children. Methods We electronically searched VIP database，CNKI database，CBMdisc，Wanfandatabase，PubMed，Excerpta Medica Database （EMBASE） and the Cochrane Library from the time of database establishment to February 2013 to identify literatures regarding pulse oximetry screening for CHD in asymptomatic children. Data extraction was performed by two researchers independently. Quality of the included literatures was evaluated with qualityassessment for diagnostic accuracy studies （QUADAS）. Meta-analysis was performed using RevMan 5.1.1. ResultsTwelve studies were included in this study with a total of 137 582 newborns. Fourteen QUADAS criteria were fulfilled by all the 12 studies. Among the 12 studies，only the studies with positive test results received verification using a gold standardtest，and the execution of the gold standard test was described in sufficient detail only in 1 study. There were 10 studies in which the gold standard test results were interpreted with knowledge of the diagnostic test results. Meta-analysis showed that pooled sensitivity and specificity of pulse oximetry test for the diagnosis of CHD were 22% with 95% CI （19%，25%） and 99% （99%，99%） respectively. Pooled positive likelihood ratio （LR＋） and negative likelihood ratio （LR-） were 157.30 with 95% CI （11.80，2 096.95） and 0.61 with 95% CI （0.46，0.82） respectively. Pooled diagnostic odds ratio was 398.25 （34.5，4 596.81）. The area under summary receiver operating characteristic （SROC） curve was 0.809，and Q index was 0.744. Conclusion Pulse oximetry is a lowly sensitive and highly specific diagnostic method for children with CHD，and is helpful for early diagnosis of CHD.

Diagnosis and Management of Concealed Intrathoracic Anastomotic Leak of Esophagus

Abstract：　Objective　To investigate diagnosis and treatment of concealed intrathoracic anastomotic leak of the esophagus.　Methods　We retrospectively analyzed the clinical data of 32 patients who presented with unexplained sepsis （temperature＞38 ℃ and elevated white blood cell count） after esophagectomy and intrathoracic anastomosis for esophageal　carcinoma or gastric cardia carcinoma in Affiliated Hospital, Medical College of Qingdao University from January 2006 to December 2010. All the patients underwent oral water-soluble contrast esophagogram and oral water-soluble contrast computerized tomography of the chest. None of the patients had any sign of contrast leak in these diagnostic examinations, but their chest computerized tomography all showed peri-anastomotic bubble and encapsulated effusion. Fifteen patients were treated as concealed intrathoracic anastomotic leak of the esophagus, including fasting, broad spectrum antibiotic treatment, prolonged gastrointestinal decompression and enteral nutrition via naso-intestinal feeding tube. The other 17 patients were not treated as anastomotic leak of the esophagus and only received broad spectrum antibiotic treatment. Results None of the 15 patients who were treated as concealed intrathoracic anastomotic leak finally developed anastomotic leak proved by oral water-soluble contrast esophagogram and computerized tomography of the chest （0%, 0/15）. Among the 17 patients　who were not treated as anastomotic leak, fourteen patients developed anastomotic leak later （82.4%, 14/17）, 2 patients died of aorto-esophageal fistula and 3 patients died of multiple organ dysfunction syndrome.　Conclusion　Peri-anastomotic bubble and irregular encapsulated effusion in oral water-soluble contrast esophagogram and computerized tomography of the chest should be considered as specific signs of concealed intrathoracic anastomotic leak of esophagus after esophagectomy and intrathoracic anastomosis. Patients with such signs should be treated as anastomotic leak.

Risk Factor Analysis and Establishment of a Mathematical Prediction Model to Evaluate the Probability of　Malignancy in Patients with Small Pulmonary Nodules

Objective To analyze risk factors of malignancy in patients with small pulmonary nodules （diameter ≤2 cm） using univariate analysis and multivariate logistic regression，and establish a mathematical prediction model to estimatethe probability of malignancy. Methods Clinical data of 147 patients with small pulmonary nodules who underwentsurgical resection with definite postoperative pathological diagnosis from January 2005 to September 2012 in the 161st Central Hospital of PLA were retrospectively analyzed. There were 84 male and 63 female patients with their age of 31-78（56.2±10.1） years. Univariate analysis using Chi-square test or t test was performed to analyze risk factors including patientage，gender，symptoms，history and quantity of smoking，history of heavy drinking，history of tumor，tumor site，diameter，lobulation，spiculation，pleural indentation，ground-glass opacity，cavity，enlarged hilar and mediastinal lymph nodes.Independent predictors of malignancy were screened with multivariate logistic regression analysis. A mathematical predictionmodel was built to estimate the probability of malignancy and then examined. Results Univariate analysis showed that there was statistical difference in patient age（t=7.146，P＜0.001），heavy smoking history（χ2=6.169，P=0.013），nodule diameter（t=3.375，P=0.001），spiculation（χ2=5.609，P=0.018），lobulation（χ2=5.675，P=0.017），and pleural indentation（χ2=12.994，P＜0.001）between benign and malignant small pulmonary nodule groups. Multivariate logistic regression analysis showed that patient age （OR=1.110，P=0.000），nodule diameter （OR=2.050，P=0.029），lobulation （OR=1.672，P=0.045），spiculation（OR=2.054，P=0.032） and pleural indentation（OR=4.090，P=0.024）were independent predictors of malignancy in patients with small pulmonary nodules （P＜0.05） . The mathematical prediction model to estimate the probability of malignancy was：Logit （P） =ez/ （1 ＋ ez），Z=-6.657 ＋ （0.104×age） ＋ （0.718×diameter） ＋ （0.720×spiculation） ＋（0.514×lobulation） ＋ （1.409×pleural indentation），and e was natural logarithm. Both Hosmer-Lemeshow test （χ2=1.802，P=0.986） and maximum likelihood ratio test （Cox-Snell R2=0.310，Nagelkerke R2=0.443） showed satisfactory goodness of fit. The diagnostic accuracy was 85.71%，sensitivity was 87.50%，specificity was 81.40%，positive predictive value was 91.92%，and negative predictive value was 72.92% when the cut-off value was 0.58. Conclusions Patient age，nodule diameter，spiculation，lobulation and pleural indentation are independent predictors of malignancy in patients with small pulmonary nodules. The mathematical prediction model can accurately estimate the probability of malignancy for patients with small pulmonary nodules.

Diagnosis and Treatment of 34 Patients with Spontaneous Esophageal Rupture

Objective?To investigate clinical characteristics， diagnosis， and treatment for patients with spontaneous　esophageal rupture， and improve clinical diagnostic and treatment level.?Methods?We retrospectively analyzed the　clinical data of 34 patients with spontaneous esophageal rupture who were treated in Subei People’s Hospital from January 1996 to June 2010. There were 28 male patients and 6 female patients with their age ranging from 32 to 80 years old (mean 57.6 years old). Main clinical manifestations included severe chest and abdominal pain after vomiting， fever， dyspnea and shock. The duration between disease onset and establishing diagnosis ranged from 4 hours to 7 days. Thirteen patients received conservative treatment including chest drainage， retrograde gastrointestinal decompression and enteral nutrition through jejunostomy. Twenty one patients received surgical treatment including layered anastomosis of the ruptured esophagus， retrograde gastrointestinal decompression and enteral nutrition through jejunostomy.?Results?All the patients were cured without in-hospital death. The mean hospital stay of the 13 patients who received conservative treatment was 46 days， while that of the 21 patients who received surgical treatment was 17 days. All the ruptured esophagus were one-stage healed. All the 34 patients were followed up from l to 8 years， including 11 patients in the conservative treatment group and 19 patients in the surgical treatment group， but 4 patients was lost during follow-up. All the patients had a normal diet without symptoms of esophageal stricture， reflux esophagitis or chronic thoracic empyema.?Conclusion　Spontaneous esophageal rupture is a thoracic emergency with a high misdiagnosis rate and mortality．Early diagnosis， early surgical repair of ruptured esophagus and satisfactory chest drainage play a vital role in the treatment for patients with spontaneous rupture of esophagus.
