0.05). Conclusion The g.168_185del polymorphism of the promoter in DJ-1 gene does not a significant risk factor for PD in this population.

Three-dimensional syndrome differentiation is a new mode of syndrome differentiation of exopathic febrile diseases, which is based upon the six meridian syndrome differentiation initiated in Treatise on Cold Attack and defence-qi-nutrient-blood and triple-Jiao syndrome differentiation in the art of warm disease of traditional Chinese medicine. Syndromes appeared in the course of cold pathogenic diseases and warm diseases were differentiated through the survey of clinical cases and observation on syndrome features of exopathic febrile diseases, by applying means of analyzing, reasoning, concluding and deducting, from the stadium, location and nature of the disease. Three-dimensional syndrome differentiation theory explains and generalizes pathological mechanism and types of syndrome on acute exopathic febrile diseases roundly, has constructed theoretical frame and synthetical model of syndrome differentiation of exopathic febrile diseases. However, any new method of syndrome differentiation can not be leave nothing to be desired in the beginning, so it is proposed that we must develop epidemiologic investigation on syndromes of exopathic febrile diseases sequentially, make models of clinical commonly seen syndromes of exopathic febrile diseases and dispose fuzzy phenomenon of syndrome by applying mathematical method. By above measures, three-dimensional syndrome differentiation will be perfected gradually, therefore, it can provide scientific theoretical basis for the treatment of exopathic febrile diseases.

Objective To evaluate the application of tubular stomach gastroesophagostomy on the life quality after esophagectomy surgery.Methods From March 2011 to September 2011,66 cases of esophageal cancer patients were divided in two groups in randomized principles.Tirty-four cases in group of tubiform gastro surgery whose the stomach was cut into tubiform stomach in width of 4 cm.And 32 cases of conventional group and whose surgery method was adopted to maintain whole stomach but cut the cardia.And then,using statistical methods,life quality after esophagectomy (treatment related symptoms,general symptoms,daily life,social life,emotional activities) and the perioperative complications were evaluated in 3,6,12,24 months in comparison and analysis.Results Sixty-six surgeries of both group patients were successfully performed,tumor resection rate was 100％,and there was no intraoperative accident also no perioperative death.There was no statistical significance of perioperative complications of 2 groups (P ＞ 0.05).Life quality of tubiform gastro group had improved apparently more than conventional group at the 3rd,6th,12th and 24th month after surgery(78.68 ±2.23 vs 65.94± 4.13,83.79 ± 2.40 vs 66.84 ± 5.86,86.41 ± 1.94 vs 67.09 ± 4.43,89.02 ± 1.71 vs 68.88 ±3.53,P＜0.05).At each time point,there were statistically significant differences between tubiform gastro group and conventional group on treatment related symptoms,general symptoms,daily life,emotion activities (P ＜0.05).At the 3rd,6th month after surgery,tubiform gastro group and the conventional group had no statistically significant difference in the aspect of social life (P＞0.05).In the conventional group,the evaluation of quality of life at each time point after surgery and before a point in time in the same group showed no statistical significance (P＞0.05).Conclusion Tubiform gastro esophagectomy has a positive influence on life quality of patients of esophageal cancer after surgery prospectively.

Objective Thoracic cavity fistula following esophagus carcinoma resection is a serious complication with a high mortality.This study aims at a better therapy for thoracic cavity fistula following esophagus carcinoma resection by summarizing the ex-perience with the four-tube strategy ( jejunal fistula tube, stomach tube, chest drainage tube, and nasal fistula tube) in the treatment of the complication. Methods We retrospectively analyzed the clinical data about 62 cases of thoracic cavity fistula following esopha-gus carcinoma resection, 35 treated with the four-tube strategy ( treatment group) and the other 27 with the three-tube ( stomach tube, chest drainage tube, and nasal fistula tube) method ( control group) .We compared the hospital days, wound healing time, mortality, and incidence of anastomotic stenosis at 6 months after operation between the two groups of patients. Results Compared with the controls, the treatment group showed remarkable decreases in the hospital days (P<0.05), wound healing time (P<0.05), and mortality (P<0.05), but no statistically significant difference was observed in the incidence rate of anastomotic stenosis at 6 months after operation between the two groups of patients ( P >0.05 ) . Conclusion Compared with the three-tube method, the four-tube strategy has the advantages of shorter healing time and lower mortali-ty, and therefore is preferable for the treatment of thoracic cavity fis-tula following esophagus carcinoma resection.

AIM:To evaluate the effect of microRNA-155(miRNA-155) on the regulation of angiogenesis in diabetic rats with cerebral ischemic injury .METHODS: Adult male Sprague-Dawley rats were randomly divided into 5 groups:sham group, cerebral ischemia group , diabetic cerebral ischemia group , diabetic cerebral ischemia +miRNA-155 inhibitors group and diabetic cerebral ischemia +scramble group .Diabetes model was made by injection of streptozocin and permanent cerebral ischemic model was developed by suture-occluded method .The scores of neurological deficit and infarct volume were estimated at 24 h after cerebral ischemia .miRNA-155 level was detected by real-time polymerase chain reaction.The expression of platelet endothelial cell adhesion molecule-1 ( PECAM-1/CD31 ) and vascular endothelial growth factor ( VEGF) was detected by Western blotting .RESULTS:miRNA-155 inhibitor significantly reduced miRNA-155 levels in the ischemic cortex (P<0.05), improved the scores of neurological deficit , reduced infarction size and up-regulated the levels of CD31 and VEGF (P<0.05).CONCLUSION:miRNA-155 has a critical role in the regulation of angiogenesis in diabetic rats with cerebral ischemia .Down-regulation of miRNA-155 using miRNA-155 inhibitor attenuates brain infarct injury in diabetic rats .

Objective The onset and progression of lung cancer correlate closely to individual genetic background .This study evaluated the correlation between the onset risk of lung cancer and short tandem repeat (STR) polymorphisms in order to find a new pathway for investigating the pathogenesis of lung cancer . Methods Using PCR and electrophoresis on 15 STR loci , we studied the gene and genotype frequencies of peripheral vein blood specimens from 120 lung cancer patients and 156 healthy individuals in Nan-jing area.According to the differences in the allele distribution of the 15 STR loci, we evaluated the susceptive and/or resistant factors relevant to lung cancer . Results There were statistically significant differences between the lung cancer patients and healthy controls at alleles 10, 15.2, and 16 of the loci CSF1PO, D19S433, and D3S1358 (P<0.05, OR>1), as well as at alleles 14 and 14.2 of the loci CSF1PO and D19S433 (P<0.05, OR<1). Conclusion It is possible that alleles 10, 15.2 and 16 of the loci CSF1PO, D19S433, and D3S1358 are susceptive factors and alleles 14 and 14.2 of the loci CSF1PO and D19S433 are resistant factors relevant to lung cancer .

Objective to investigate the clinical effect of negative pressure suction by double caping pipe on cervical esophagus fistula after esophageal carcinoma surgery,and search for the effective treatment of cervical anastomotic fistula after esophageal carcinoma surgery.Methods The clinical data of 140 patients with cervical esophagus fistula after esophageal carcinoma surgery in Nanjing General Hospital of Nanjing Command from September 2004 to September 2015 were retrospective analyzed.Among them,85 cases were treated with low negative pressure suction by double caping pipe as experimental group,55 cases were treated with conventional drainage and dressing as the control group.The length of hospital stay,healing time,dressing frequency,neck bleeding risk,anastomotic stenosis and mortality rate between two groups were analyzed and compared.Results The length of hospital stay,the time of wound healing,the frequency of wound change dressing,the rate of neck bleeding in experimental group were (15.94± 1.57)d,(8.00± 1.55)d,(6.22± 1.52)times,1.18％ respectively,significantly lower than that of control group ((23.64 ± 2.36) d,(15.64 ± 2.08) d,(27.56±3.58) times,12.24％;P=0.000,0.000,0.000,0.029).While the rate of anastomotic stenosis after half a year in experimental group was 17.65％,lower than that of the control group (23.64％),the difference was no significant(P=0.387).Conclusion The treatment on cervical esophagus fistula with low negative pressure suction by double caping pipe has superiorities on hospitalization and healing time,dressing frequency,neck bleeding risk,mortality,and does not increase the incidence of anastomotic stenosis,and it can achieve a better therapeutic effect compare with the conventional drainage and dressing.

BACKGROUND:Matrix metal oproteinase-13 is most active in the degradation of col agen type II in the extracel ular matrix of cartilage. Interleukin-1 (IL-1) is thought to be the inducer of matrix metal oproteinases, and participates in the degradation and degeneration of articular cartilage. OBJECTIVE:To study the influence of IL-1βon microRNA-27b (miR-27b) and matrix metal oproteinase-13 expression of chondrocytes in rats. METHODS:Chondrocytes isolated from seven male Wistar rats were cultured and divided into IL-1βstimulation group and control group. No stimulus was given in the control group;10μg/L of serum free medium was used to culture rat chondrocytes in the IL-1βstimulation group. Cel growth was observed at 0, 24, and 48 hours under an inverted microscope. miR-27b and matrix metal oproteinase-13 expression in the cultured chondrocytes were detected. RESULTS AND CONCLUSION:The relative expression of matrix metal oproteinase-13 in rat chondrocytes was gradual y increased when induced by IL-1βat 0, 24, and 48 hours (P<0.05). Expression of miR-27b and miR-31 in rat chondrocytes at 24 and 48 hours induced by IL-1βgradual y decreased (P<0.05);conversely, expression of MiR-26a, miR-26b, miR-23, and miR-204 gradual y increased (P<0.05). After 48 hours of IL-1βinduction, expression of miR-27b was the lowest in rat chondrocytes (P<0.05). These findings suggest that IL-1βinhibits miR-27b expression, strengthens the expression of matrix metal oproteinase-13, and damages chondrocytes, contributing to both the onset and progression of osteoarthritis.

Objective To summary the experience of T4 esophageal carcinoma surgery and to explore the methods and operating skills on descending thoracic aortic resection with prosthetic vascular graft replacement in patients with T4 locally advanced esophageal carcinoma invading descending thoracic aorta.Methods From Jan.2001 to Dec.2010,36 patients with esophageal carcinoma underwent esophagectomy and descending aortic replacement simultaneously in our hospital.The clinical data were retrospectively reviewed.All patients had a left posterior lateral incision via the 6th intercostal space.The vascular adventitia of the descending thoracic aorta in the left side was incised,and the aorta was clamped in the proximal and distal side of the invaded segment.Then the invaded segment was resected and replaced with artificial vessels.Esophageal carcinoma was radically resceted,and left cervical esophageal-gastro anastomosis was performed in all patients.Results Radical resection of esophageal carcinoma was achieved in all patients.There was no perioperative death,or severe complications such as paraplegina,acute renal failure and intestinal dysfunction occurred.Two patients had chylous hydrothorax,and one had late stage anastomotic stoma fistula.The post-operative hospital stay was 10-42 d,mean (15.5 ± 7.2 )d.The pathological examination revealed that all the patients had squamous cell carcinoma.The aortic tunica adventitia was invaded in all the patients,9(25％ ) had tunica media invasion,and there was no tunica intima invasion observed.The 1-,3-,and 5-year survival rate was 80.6％,46.2％ and 20.0％ respectively.Conclusion Combined esophagectomy and descending aortic replacement for locally advanced T4 esophageal carcinoma invading aorta can be considered as radical operation for selected patients,and it can improve the survival rate and life quality of the patients.
