ABSTRACT
Objective To observe the relationship between the peripheral blood IFN-γ secretion level and prognosis in the patients with early stage of acute cerebral hemorrhage.Methods Sixty-six inpatients with acute intracerebral hemorhage in the emergency department of this hospital from July 2015 to August 2016 were selected as the experimental group,and 60 healthy people in the physical examination center served as the blank control group.The peripheral blood mononuclear cells(PBMCs) and plasma were separated.The helper T cells(Th)1/Th2 eytokines(IFN-γ,IL-2,IL-4 and IL-10) were detected by using ELISA.The flow cytometry was used to detect intracellular cytokines;the disease condition change from 1 d of onset to 30 d in the experiment group was analyzed by using NIHSS.The relationship between the cytokines and prognosis on 30 d evaluated by NIHSS score was analyzed.Results The peripheral blood IFN-γ level had statistically significant difference between the two groups(P＜0.05),while the levels of IL-2,IL-4 and IL-10 had no statistical difference(P＞0.05).The peripheral blood IFN-γ secretion level during early stage in the experimental group was positively correlated with the prognosis(P＜0.05).Conclusion The increase of peripheral blood IFN-γ during early stage is correlated with the poor prognosis in the patients with acute intracerebral hemorrhage.
ABSTRACT
Objective To investigate the expression of deleted in breast cancer 1 (DBC1) in small cell lung cancer (SCLC) and its correlation with prognosis. Methods The clinical data of 73 SCLC patients who underwent surgery in Shengjing Hospital of China Medical University between December 2009 and June 2013 were retrospectively analyzed. The expression levels of DBC1 in lung cancer tissues were detected using quantitative real-time polymerase chain reaction (RT-PCR). The correlation between the expression of DBC1 and the clinicopathological parameters of SCLC patients were analyzed. The Kaplan-Meier method was used to analyze the relationship between DBC1 expression and survival of the SCLC patients; independent factors of prognosis were analyzed using the COX proportional hazards model. Results The expression of DBC1 was significantly associated with recurrence and metastasis (P ＜ 0. 05), whereas it was not significant correlated with the patients gender, age, pathological type, stage, and smoking history. Results of the Kaplan-Meier analysis showed that survival rates were significantly decreased in patients with higher DBC1 expression levels when compared to those with lower expression levels (P ＜ 0. 01). COX proportional hazard model analysis showed that the expression of DBC1 can be used as an independent factor for the prognosis of SCLC patients. Conclusion High expression of DBC1 is correlated with recurrence and metastasis of SCLC, and associated with poorer prognosis in SCLC patients.
ABSTRACT
Objective To evaluate the clinical significance of single-incision video-assisted thoracoscopic surgery(SI-VATS)in elderly patients undergoing pneumonectomy. Methods The clinical data of elderly patients received pulmonary resection by SI-VATS and three-port video-assist-ed thoracoscopic surgery(TP-VATS)last year were analyzed. Results The SI-VATS group was significantly better than the TP-VATS group in in-cision length,drainage time,as well as the 1st,3rd,7th day VAS score and one month satisfaction after operation(all P0.05). Conclusion SI-VATS pul-monary resection is safe,feasible and with less invasive.
ABSTRACT
Objective To investigate the expressions of tenascin(TN)and microvessel density(MVD) in esophageal squamors cell carcinoma.Methods The experessions of TN and MVD were observed by immunohistochemiccal methods in 91 cases of esophageal carcinoma and 47 cases of ono-esophageal carcinoma.Results ①The expression of tenascin in esophageal cancer was much high than that in t he normal tissue(t=12.331,P＜0.01).②Over expression of TN was related to th length(F=12.373,P＜0.01),the invasion(F=11.039,P＜0.01),the lymphatic metastasis(F=6.882,P=0.01)and the pathologic trade(F=5.060,P=0.003)of cancer.③The expression fo MVD in the esophageal carcinoma tissues was stonger than that in the nonesophageal carcinoma tissues(t=6.023,P＜0.01).④Over expression of NVD wsa related to the length(F=9.033,P＜0.01),the lymphatic metastasis(F=12.429,P＜0.01)and the pathologic grade(F=5.717,P＜0.01)of cancer.⑤The positive expressions of TN and MVD were associated(P=0.001).Conclusion TN;s voerexpressions may be a biological marker in esophageal squamous cell carcinoma..It was associated with the expression of MVD.The levels of TN and NVD were useful molecular markers for evaluating malignancy degree and lymph node metastasis of esopageal carcinoma.
ABSTRACT
BACKGROUND: Esophageal replacement or reconstruction should be performed after esophageal resection. There are still no suitable substitutes for esophagus if the conventional esophageal substitutes cannot be used.OBJECTIVE : To investigate the feasibility of applying a pulmonary tissue with vascular pedicle to repair the intrathoracic esophageal defect.DESIGN: A prospective animal investigation.SETTING: Department of Thoracic Surgery, Second Hospital Affiliated to China Medical University.MATERIALS: This trial was carried out in the laboratory of Department of Thoracic Surgery, Second Hospital Affiliated to China Medical University during January 2003 to June 2004. Fourteen adult mongrel dogs of either gender, with body mass of 12 to 18 kg, were provided by Animal Room, Second Hospital Affiliated to China Medical University (License No.SYXK (Liao) 2003-0019).METHODS: Of 14 anesthetized dogs, the middle lobe of right lung was dissected and its right middle lobar bronchus was ligated without damaging pulmonary and bronchial vessels in order to make pulmonary flap. A part of full-layer intrathoracic esophageal wall was resected, which was 4 cm long and 1/2 to 2/3 circled esophageal wall. The defect was patched by pulmonary tissue with vascular pedicle which was inosculated with esophageal cross section. On the 3rd day after operation, intravenous transfusion was performed to maintain nutrition. Qn the 7th day after operation, the dogs were given oral liquid soft food gradually 2 weeks after the operation. The access to the food and the survival of dogs were observed. Every 2 dogs were sacrificed respectively at the 2nd, 4th, 6th, 8th and 10th postoperative weeks. To observe the healing of esophageal defect, light microscope, transmission electron microscope, esophagography and endoscope were used in this study.MArN OUTCOME MEASURES: ①Survival situation and access to food of dogs after operation. ② The healing of esophageal defect of dogs.RESULTS: Three of fourteen dogs died within one week after operation. Eleven dogs survived. ① The survival and access to food of experimental dogs after operation: One dog was alive without problems for more than 170 weeks. The living dogs could be fed orally on the 7th day after operation. ② The healing at esophageal defect of experimental dogs:At the 2nd week after operation, the esophageal defect was covered with collagen layer and inflammatory exudation. A little epithelization was observered at free edge of the anastomosis, which was 1 to 2 layers of stratified squamous epithelium cells. At the 4th to 6th weeks after operation, the internal surface of the defect was covered with 3 to 5 layers of stratified epithelium cells. At the 8th to 10th weeks after operation, the luminal surface of the defect was covered with 6 to 8 layers of stratified epithelium cells. The pathological changs of pulmonary flap mainly included pulmonary alveoli atelectasis and pulmonary fibrosis, and some inflammatory cells without infective focus were observed. In the transmission electron microscope examination, newborn stratified squamous epithelium cells were. found on the surface of pulmonary tissue flap at esophageal defect.CONCLUSION: It is feasible to repair the partial irregular intrathoracic esophageal defect with the autologous pulmonary flap in dogs.
ABSTRACT
Objective: The purpose of our experiment is to use new type esophageal prosthesis, which is pulmonary tissue with vascular pedicle, to repair the partial esophageal defect. Methods: Twelve adult mongrel dogs were used for the study. Middle lobar bronchus of right lung was ligated and incised, so the pulmonary tissue with vascular pedicle was made. A 4 cm long and 1/2～2/3 circled esophageal wall, and full-thickness defect was created. The defect was patched by pulmonary tissue with vascular pedicle. Results: Seven dogs were put to death at planned times after the reconstructive operation. One dog is still alive without any problems for more than 12 months. One dog survived 38 days and then died of chronic empyema. The other three dogs died of anastomotic leak at 5～7 days after operation. The living dogs could be fed orally at seventh day after operation. Epithelization was found in the luminal surface of the defect. Conclusion: It was feasible that the partial esophageal defect was replaced by pulmonary tissue with vascular pedicle.
