Groin incarcerated hernia and groin strangulated hernia in adults are common acute abdominal disease,usually with aging,male-dominated inguinal direct and indirect hernia and female dominated femoral hernia,high mortality.Groin hernia medical history,hernia specialist checkup and imaging examination are quick and accurate diagnosis of adult groin incarcerated and strangulated hernia necessary prerequisites.Traditional hernia surgery,tension-free repair,laparoscopy tension-free repair are commonly used in emergency surgery of groin incarcerated hernia and strangulated hernia in adults.The aim of this article is to summarize the timing of surgery and surgical methods of groin incarcerated and strangulated hernia in adults.

Objective:TO explore the effectiveness of splenic tissue autotransplantation in restoring host defense. Methods: Rabbits were divided into three groups,Sham Operation(SO), Splenic Autotransplantation(SA)and Total Splenectomy(TS), and dynamic changes in histology and immunology were observed for over 24 weeks. Results: Histologic study shows that the white pulps were poorly developed and central arterioles disappeared in the regenerated splenic tissue. The weight of regenerated spleens recovered six months later in SA was 11% of that in SO, and was significantly reduced comparing with the implanted weight( P ＜0.05). Tere were no significant difference in the number of T lymphocytes and the levels of serum lysozyme among the three groups. A poor antibody response by the rabbits of SA and TS as compared to those of SO was noted after the primary intravenous administration with sheep red blood cells. After the challenge with type 3 pneumococci intravenously, pneumococcal clearance from bloodstream in SA did not differ significantly from that in TS,but was marKedly delayed compared with that in SO(P＜0.01). Conclusion: The results indicate that the low quantity and poor quality of the regenerated spleens may contribute to the inferior immunoprotective ability of 1/3 splenic autotransplantation. Therefore, it implies that the regenerated spleens can not fully compensate the original one in im-munology, especially, host resistance to infection.

Objective To investigate the expression of neurokinin 3 receptor (NK 3R) in normal pancreas and pancreatic cancer, and to study the localization of this receptor in pancreatic cancer Methods The expression of NK 3R mRNA was investigated using reverse transcription polymerase chain reaction (RT PCR) in normal pancreas and pancreatic cancer tissues The protein level of NK 3R was investigated by Western blot Immunohistochemistry was used to localize expression site of NK 3R Results NK 3R mRNA was overexpressed in pancreatic cancer tissue when compared with normal pancreas NK 3R protein was 1 1?0 5 in normal pancreas and 14 6?3 6 in pancreatic cancer, P

Objective To investigate the relationship between EphA2, EphrinAl and E-cadherin expressions and tumor stage and prognosis in pancreatic cancer. Method EphA2, EphrinAl and Ecadherin expressions were detected by immunohistochemistry in the tumor tissue and normal tissue specimens from 48 patients with primary pancreatic cancer. Results The expressions of EphA2 and EphrinAl were higher in the pancreatic carcinoma tissues than in the normal pancreatic tissues (P<0. 05). The E-cadherin expression was lower in the pancreatic cancer tissues than in the normal pancreatic tissues (P<0. 05). With decreasing histological differentiation, the expressions of EphA2 and EphrinAl in carcinoma tissues increased significantly (P<0. 05), while the E-cadherin expression decreased significantly (P<0. 05). The positive expressions of EphA2 and EphrinAl in the primary tumor significantly increased in stageⅢ and Ⅳ than in stage Ⅰ and Ⅱ (47. 9%vs 6. 25% , P<0. 05;47. 9% vs 8. 3%, P<0. 05), while the negative expression of E-cadherin was reversely correlated with these tumor stages (14. 6% vs 64. 6%, P<0. 05). Cox multivariate analysis showed that the clinical stage, EphA2 positive expression and E-cadherin negative expression were significantly associated with survival. Conclusion Abnormal expressions of EphA2, EphrinAl and E-cadherin were involved in the progression of pancreatic cancer and they were useful in predicting prognosis.

Objective To investigate the prognostic value of vascular endothelial growth factor C (VEGF-C) and clinicopathologic indexes in predicting recurrence following curative resection of pancreatic cancer. Methods The expressions of VEGF-C of 47 patients who underwent curative resection for curative pancreatic cancer resection were detected by Envision immunohistochemical methods. The effects of VEGF-C and clinicopathologic indexes on recurrence were assessed by the Kaplan-Meier and Cox proportional hazards model. Results The positive rates of VEGF-C were 61. 7% in = 29) and 14. 9%(n = 7), respectively, in pancreatic cancer and normal pancreatic tissues. The positive expression of VEGF-C in pancreatic carcinoma was obviously higher than the normal pancreatic tissues (P = 0. 018). The median disease-free survival time was 11. 9 months, the average disease-free survival time was 18. 4 + 2. 4 months, and the cumulative 1-year, 2-year and 3-year actuarial recurrence free survival rates were 46. 8%, 23. 4%, 14. 4%, respectively. There was a significant correlation between the VEGF-C expression and lymph node metastasis in pancreatic cancer (P = 0. 036). On Kaplan-Meier analysis, VEGF-C (P = 0. 020), tumor diameter (P = 0. 013), age (P = 0. 057) and adjuvant chemotherapy (P=0. 017) were associated with disease-free survival time. Multivariate analysis showed VEGF-C (P = 0. 009), tumor diameter (P = 0. 010) and adjuvant chemotherapy (P = 0. 017)were independent prognostic factors of disease-free survival after surgery for pancreatic cancer.Conclusion The expression of VEGF-C was higher in pancreatic cancer, and VEGF-C was correlated with lymph node metastasis. VEGF-C was the biomarker that independently predicted disease-free survival after surgery for pancreatic cancer.

Objective To study the feasibility,safety,indications and possible advantages of minimally invasive surgery over traditional open surgery in treating pancreatic body or tail lesions.Methods From December 2009 to December 2014,the clinical data of 71 patients with lesions in pancreatic body or tail who underwent minimally invasive distal pancreatectomy (MIDP) or open distal pancreatectomy (ODP) at the General Surgery of Huadong Hospital were retrospectively analyzed.There were 22 patients in the MIDP group and 49 patients in the ODP group.The operations in 15 patients in the MIDP group were performed by the Da Vinci robot-assisted surgical system and 7 patients by laparoscopic distal pancreatectomy.Results The MIDP group had a shorter time to pass first flatus [(MIDP (2.5 ± 1.0) d vs ODP (3.5 ±1.0)d,P ＜ 0.05],and shorter postoperative hospital stay [(MIDP (15.2 ± 7.9) d vs ODP (23.4 ±21.2) d,P ＜ 0.05] than the ODP group.There were no significant differences on total pancreatic fistula rate [MIDP 45.5％ (10/22) vs ODP 55.1％ (27/49),P ＞ 0.05] and symptomatic postoperative pancreatic fistula rate [MIDP 18.2％ (4/22) vs ODP 18.4％ (9/49),P ＞ 0.05] between the two groups.The MIDP group had a significant longer operative time [MIDP (246.3 ±75.3)min vs ODP (168.1 ±33.7)min,P＜0.05] than the ODP group.Conclusions Minimally invasive surgery is safe and feasible in treatment of lesions in pancreatic body or tail with less trauma and faster recovery.The application of robotic surgery has expanded the treatment options for lesions in pancreatic body or tail.

Objective To investigate the role of substance P (SP) and its neurokinin-1 receptor (NK-1R) in the pathophysiologic process of Crohn′s disease. Methods In 23 surgical patients of Crohn′s disease and 24 healthy controls, reverse transcription polymerase chain reaction (RT-PCR) was used to determine the mRNA expression of NK-1R, Western blot analysis was used to determine NK-1R protein expression levels, and immunohistochemistry was used to localize expression of NK-1R. Results Compared with normal gut NK-1R mRNA and NK-1R protein in Crohn′s disease were overexpressed. In Crohn′s disease moderate to strong intestinal NK-1R immunoreactivity was found in the lamina propria mononuclear cells, lymphoid follicles, and the surface and crypt epithelium, lymphoid follicles, submucosal vessels, smooth muscle and myoenteric plexus neurones. Conclusions In cases of Crohn′s disease, overexpression of NK-1R may disturb neuropeptides loop balance, and may be involved in the pathophysiological change in this disease.
