ObjectiveTo investigate the short-term curative efficacy of DC-CIK in comprehensive therapy of esophagus cancer. MethodsWe randomly allocated 52 patients with esophagus cancer who had preoperatively confirmed by CT on stage Ⅱ-Ⅲ B into an observation group and a control group with 26 patients in each group. There were 14 male and 12 female patients in the observation group at median age of 60 years (range:49-67 years). There were 16 male and 10 female patients in the control group with median age of 62 years (range:48-65 years).The control group received postoperative chemotherapy, and the observation group received postoperative chemotherapy combined with DC-CIK biotherapy. The combination of paclitaxel and cisplatin for four cycles was choosen as the chemotherapy regimen. Patients in the observation group were treated with DC-CIK biotherapy for 2 weeks after operation. At the fifth week they received the first cycle of chemotherapy. There was a course of biotherapy between two cycles of chemotherapy. The clinical efficacy, lymphocyte subtypes, and intracellular cytokines in peripheral blood of the patients, performance status (KPS) and adverse reactions were compared. ResultsAll patients completed the therapy regimen successfully. In the observation group, the ratios of CD3+, CD4+, CD4+/CD8+, CD56+, and CD19+ increased, and the ratio of CD8+ decreased with significant differences (P<0.05).The biotherapy significantly increased interleukin 2 (IL-2), IL-12, interferon gamma (IFN-γ) and tumor necrosis fator (TNF)-α level (P<0.05). However, in the control group, there was no significant difference between post and pre-therapy in the levels of lymphocytes and cytokines. The effective rate of KPS was 76.92% in the observation group and 46.15% in the control group with a significant difference (P=0.023). No other adverse reactions except 3 patients with fever in the observation group were found. ConclusionThe short-term curative efficacy of DC-CIK in comprehensive therapy of esophagus cancer is distinct. DC-CIK biotherapy can improve patients' immune functions and elevate their life quality, so it is likely to be an effective adoptive immunotherapy for esophagus cancer.
ObjectiveTo discuss the value of diffusion weighted imaging (DWI) in the diagnosis of placenta increta. MethodsThe clinical data of 42 patients with placenta increta admitted to Sichuan Provincial Hospital for Women and Children between May 2012 and January 2014 were retrospectively analyzed. All the patients were examined by prenatal magnetic resonance scans and DWI scans for subsequent comparison between ADC of the local convex placental region and ADC of the normal placental region and between the results of the two imaging methods. ResultsADC of the implantation area was significantly different from that of the normal placenta, so it could be used as a quantitative index. DWI had a higher sensitivity of diagnosis than conventional MRI. ConclusionCompared with conventional magnetic resonance imaging, DWI is more valuable in the clinical diagnosis of placenta increta, which provides a reliable basis for clinical treatment.
ObjectiveTo explore clinical strategies of early diagnosis and treatment of solitary pulmonary nodules (SPN), and define the importance of biological tumor markers, preoperative CT-guided localization with the combination of methylene blue and hookwire system, and video-assisted thoracoscopic surgery (VATS)for early diagnosis and treatment of SPN. MethodsWe retrospectively analyzed clinical records of 70 SPN patients in Department of Thoracic Surgery of Taixing People's Hospital from January 2011 to February 2014. There were 33 male and 37 female patients with their age of 32-87 (59.74±2.04)years. Preoperatively, patients' medical history, heart, lung, liver and kidney function, sputum cytology and bronchoscopic biopsy results were combined with biological tumor markers to make a preliminary differential diagnosis between benign or malignant SPN and surgical risk evaluation. For SPN less than 1 cm or too small for accurate intraoperative localization, CT-guided localization with the combination of methylene blue and hookwire system was routinely performed half an hour before the operation. For SPN large enough for accurate intraoperative localization, wedge resection of SPN and surrounding lung tissue was directly performed with VATS. Intraoperative frozen-section examination of resected lung specimens was preformed. If the pathological diagnosis was malignant, conventional VATS lobectomy/segmentectomy and lymphadenectomy were performed. If the pathological diagnosis was benign, the operation was then completed. Long-term follow-up was performed for SPN patients, especially patients with early-stage lung cancer. ResultsThere was no in-hospital death or postoperative bronchopleural fistula in this study. Postoperatively, there were 2 patients with pneumonia, 3 patients with pneumothorax and 1 patient with wound infection, who were all cured or improved after proper treatment. Among the 70 patients, 11 patients acquired pathological diagnosis via preoperative lung needle biopsy. Among the other 59 patients, 12 patients with eccentric SPN acquired pathological diagnosis via intraoperative biopsy, and 47 patients underwent SPN resection with VATS. Pathological diagnosis included adenocarcinoma in 19 patients, squamous cell carcinoma in 9 patients, bronchioloalveolar carcinoma in 3 patients, adenosquamous carcinoma in 2 patients, inflammatory pseudotumor in 11 patients, tuberculoma in 4 patients, granuloma in 5 patients, sclerosing hemangioma in 2 patients, lung metastasis from breast cancer in 1 patient, lung metastasis from colon cancer in 1 patient, lung metastasis from thyroid cancer in 1 patient, and lung metastasis from stomach cancer in 1 patient. All the 70 patients (100%)were followed up for a mean duration of 2-34 months, and there was no late death during follow-up. One patient with adenocarcinoma of the right upper lobe had cerebral metastasis 18 months after operation, and had been receiving radiotherapy. All the other patients had a good quality of life. ConclusionAbove clinical strategies are accurate for early diagnosis and minimally invasive treatment of SPN with good postoperative recovery and short-term outcomes.
Objective To evaluate the characteristics and reasons of complications in the patients with thoracoscopic esophagectomy. Methods We retrospectively analyzed the clinical data of 165 patients with thoracoscopic esophagectomy in our hospital from January 2013 through January 2015. There were 102 males and 63 females at average age of 67.9±8.3 years. Results The operation time was 275.3±50.2 min. The intraoperative blood loss was 230.0±110.5 ml. The number of lymph node dissection was 18.1±6.5. The volume of drainage in thoracic cavity was 750±550 ml on the third day after operation. Thoracoscopic esophagectomy surgeries were successful except that 13 patients (7.8%) converted to open operation including 6 patients (4.2%) with severe pleural adhesion, 2 patients (1.2%) with hemorrhage, 2 patients (1.2%) with arrhythmia, and 3 patients (1.8%) with abnormal oxygenation. There were 17 patients (10.8%) were with intraoperative complications including 2 patients (1.2%) with arrhythmia, 3 patients (1.8%) with abnormal oxygenation, 7 patients (4.2%) with hemorrhage caused by vascular injury, 4 patients (2.4%) with thoracic duct injury, 1 patient (0.6%) with recurrent laryngeal nerve injury. Moreover, 46 patients (27.8%) experienced postoperative complications including 23 patients (13.9%) with pulmonary infection, 6 patients (3.6%) with hoarseness, 4 patients (2.4%) with anastomotic leakage, 3 patients (1.8%) with incision infection, 2 patients (1.2%) with tracheoesophageal fistula, and 2 patients (1.2%) with pneumothorax. Unexpectedly, five patients underwent re-operation due to chylothorax (n=3, 1.8%) and hemorrhage (n=2, 1.2%). One patient (0.06%) died of acute pulmonary embolism. Conclusion Serious adhesion in abdominal cavity, abnormal of lung and heart. And bleeding are the main reasons caused transferring open thoracic surgery operation in patients with thoracoscopic esophagectomy. Lung infection, hoarseness, and anastomotic leakage of neck are the most common postoperative complications. And acute pulmonary embolism is the main cause of postoperative death. Proper precautions to decrease the morbidity of complication are necessary.
ObjectiveTo investigate the effect and mechanism of silent information regulator 1 (SIRT1)in invasion of human gastric cancer. MethodsThe expressions of SIRT1 protein and vascular endothelial growth factor A (VEGF-A) protein in 46 cases of gastric cancer were tested by immunohistochemical SP method; the effect of expressions of SRIT1 and VEGF-A protein on prognosis of gastric cancer was analyzed by Kaplan-Meier test; the expressions of SRIT1 and VEGF-A protein in human gastric mucosa GES-1 cells and SGC7901 cells were tested by Western blot method; after the interference of siRNA on SIRT1 gene, expressions of SRIT1 and VEGF-A protein were also tested by Western method, and the invasion ability was determined by Transwell test. ResultsCompared with normal gastric mucosa tissues, expression levels of SIRT1 and VEGF-A protein of gastric tissues were both higher (P < 0.050), and survival situation of patients with SIRT1-positive (P=0.001) or SIRT1-positive and VEGF-A-positive (P=0.006) were both bad, but there was no significant difference on the relationship between prognosis of gastric cancer and expression of VEGF-A protein (P=0.091). Expression levels of SITR1 protein (P=0.010) and VEGF-A protein (P=0.020) in GES-1 cells were both higher than those of SGC7901 cells. In siRNA positive group, expressions of SIRT1 and VEGF-A protein (P=0.010) of SGC7901 cells down-regulated, and invasion ability decreased (P=0.000). ConclusionsSIRT1 gene may promote the expression of VEGF-A protein and the invasion ability of gastric cancer, it may be a therapeutic target of invasion inhibition for gastric cancer.
