Objective To summarize the experience in the diagnosis and treatment of traumatic spleen rupture.MethodsThe diagnosis and treatment of consecutive 293 patients with traumatic spleen rupture from January 1992 to October 2000 were reviewed.ResultsThe diagnosis was established by the history of injury, clinical presentations, diagnostic peritoneal punctures, abdominal ultrasonography and/or CT. The accuracy rate of diagnosis was 96 3% (282/293). Thirty one patients were treated nonoperatively and cured. Two hundred and fifty of 259 patients treated operatively were cured.Seven had postoperative complications with effusion in the splenic fossa.The total cure rate was 95 9%(281/293).Twelve patients died of uncontrolable hemorrhage or severe multiple injuries.ConclusionsSplenectomy for the treatment of traumatic spleen rupture is satisfactory.The morbidity and mortality of splenectomy are low.

Objective To improve the understanding of acute typhlitis.Methods all 5 cases of acute typhlitis from February 1999 to August 2001 were reviewed,5 cases were preoperatively misdiagnosed as acute appendicitis and subsequently performed emergency operations.Moreover,misdiagnosis was made intraoperatively as tumor in 2 cases,Crohn disease in 2 cases and diverticulitis in 1 case.Right hemicolectomy was performed in 4 cases;resection of necrotic mass and ileostomy was performed in 1 case.Results The pathologic change was acute non-specific inflammation of cecum in 5 cases.All cases recovered uneventfully.They are in good condition during the follow-up range 4 to 30 months.Conclusions The clinical manifestation of typhlitis was nonspecific.It was extremely difficult to diagnose preoperatively.Inflammatory mass of external lateral wall of cecum was characteristic finding of typhlitis during laparatomy.It is difficult to differentiate from tumor or Crohn disease at intraoperation.Right hemicolectomy was satisfactorily recommended.

Objective To investigate the relationship between continuous hyperglycemia and the progression of early acute pancreatitis (AP) Methods Five hundred and twelve AP patients were included in this study, in which 418 patients were mild acute pancreatitis (MAP) and 94 were severe acute pancretitis (SAP) Fasting blood sugar was determined and APACHE Ⅱ score was calculated on admission, 2nd and 3rd day of hospitalization respectively Serum tumor necrosis factor (TNF?) and C reaction protein (CRP) levels were determined on the 2nd day of hospitalization Results The incidence of hyperglycemia was higher in SAP patients than that in MAP patients (74 5% vs 25 8%, P =0 001) In SAP, APACHE Ⅱ score in continuous hyperglycemia group (CHG) was significantly higher than that of non continuous hyperglycemia group (NCHG) on admission, 2nd and 3rd day of hospitalization respectively (13?4 vs 11?3, P =0 017; 13?4 vs 11?3, P =0 010; 14?4 vs 10?4, P =0 010, respectively) Continuous hyperglycemia was related to the severity of SAP ( ? 2=7 77, P =0 005) Moreover, serum TNF? and CRP levels of the CHG were also markedly higher than that of NCHG (20?14 vs 14?11, P =0 019; 123?81 vs 93?55, P =0 036, respectively) Conclusion Continuous hyperglycemia might be a risk factor for the aggravation of early acute pancreatitis

Objective: To observe the antiasthmaf ic, anti-inflammatory and immunological effects of Gubenchuansoukang Granule. Methods: The rats asthma model was established by ovalbumin sensitization. The model was identified by the study of the asthma incubation period and the total white cells counts in bronchoalveolar lavage fluid (BALF). The anti-inflammatory effect was observed by the acute inflammation and chronic inflammation induced xylene and agar. To observe the effect of Gubenchuansoukang Granule on humoral immunity and cellular immunity induced by chicken red blood cell and 2, 4-dinitrochlorobenzene. Results: Gubenchuansoukang Granule could lengthen the asthma incubation period, reduce the quantity of total white cells in BALF, against the acute inflammation and chronic inflammation, and restrain the humoral immunity and cellular immunity. Conclusion: Gubenchuansoukang Granule had antiasthmafic, anti-inflammatory and immunosuppression effects.

Magnetic resonance (MR) imaging is an important tool for prostate cancer diagnosis, and accurate segmentation of MR prostate regions by computer-aided diagnostic techniques is important for the diagnosis of prostate cancer. In this paper, we propose an improved end-to-end three-dimensional image segmentation network using a deep learning approach to the traditional V-Net network (V-Net) network in order to provide more accurate image segmentation results. Firstly, we fused the soft attention mechanism into the traditional V-Net's jump connection, and combined short jump connection and small convolutional kernel to further improve the network segmentation accuracy. Then the prostate region was segmented using the Prostate MR Image Segmentation 2012 (PROMISE 12) challenge dataset, and the model was evaluated using the dice similarity coefficient (DSC) and Hausdorff distance (HD). The DSC and HD values of the segmented model could reach 0.903 and 3.912 mm, respectively. The experimental results show that the algorithm in this paper can provide more accurate three-dimensional segmentation results, which can accurately and efficiently segment prostate MR images and provide a reliable basis for clinical diagnosis and treatment.
