Objective To investigate the selection and efficacy of operative medality for pancreatic transec-tion with major duct injury. Methods The clinical data were retrospectively analyzed in 21 patients with pancreatic disruption. They were treated in our hospital from Jan. 1995 to Feb. 2009. There were 14 males and 7 females in these cases with a mean age of 26 years (range 9-53 years). The trauma causes of them were blunt injuries in 13 and patent injuries in 8 cases. The injury grade (according to American Association for the Surgery of Trauma) distribution for these patients was grade Ⅲin 8 cases, grade Ⅳ in 8 cases, and grade V in 3. The early emergency operation was performed in eighteen within 12 hours, and delayed opera-tion was in three cases. Of these operative medalities, Roux-en-Y distal panereatojejunostomy was in 10 ca-ses, pancreatoduodenectomy was in 3, modified duodenal diverticulizatian was in 2, distal pancreatectomy was in 3, tube installing in major duct and external drainage, and suture of pancreatic section was in 2, su-ture of two broken sides in 1 (Roux-en-Y distal pancreatojejunostomy in second time). Results Twenty patients were cured, and one was died after a procedure of pancreatoduodenectomy. The postoperative pan-creatic fistula happened in 3 cases and recovered well with conservative line of management. Conclusions For improving the outcome of pancreatic transection, the earlier exploratory laparotomy and carrying out concept of "Damage Control Surgery" are critical. The individual operative modality based on the grade should be a-dopted in the surgical procedure.

This study evaluated the change in regional left ventricular myocardial function in rats following acute occlusion of the left anterior descending coronary artery (LAD) by using two-dimensional speckle tracking imaging (2D-STI). Sixty Wistar rats were randomly divided into two groups, a myocardial infarction (MI) group, in which 50 rats were subjected to LAD occlusion for 30-45 min, and a sham-operated (SHAM) group that contained 10 rats serving as control. Echocardiography was performed at baseline and 1, 4 and 8 week(s) after the operation. High frequency two-dimensional images of left ventricular short axis at papillary muscle level were recorded. Peak systolic radial strain (PRS) and circumferential strain (PCS) were measured in the mid-ventricle in short-axis view by using EchoPAC workstation. Left ventricular internal diameter at diastole (LVIDd) and systole (LVIDs), fractional shortening (FS), ejection fraction (EF) and left ventricular mass (LVM) were measured by anatomical M-model echocardiography. Infarct size was measured using triphenyl tetrazolium chloride (TTC) staining 1 week and 8 weeks after the operation. Fibrosis of left ventricular myocardium was displayed using Van Gieson staining 1 week after the infarction. In terms of the TTC staining results, the left ventricle fell into three categories: infarcted, peri-infarcted and remote myocardial regions. Compared with those at baseline and in the SHAM group, (1) PRS and PCS in the infarcted, peri-infarcted and remote myocardial regions were significantly decreased in the MI group within 1 week after the operation (P<0.05) and the low levels lasted 8 weeks; (2) Compared with those at baseline, LVIDd, LVIDs, FS, EF and LVM in the MI group showed no significant difference 1 week after the operation (P>0.05). However, LVIDd, LVIDs and LVM were increased significantly 4 and 8 weeks after the operation (P<0.05), and FS and EF were decreased substantially (P<0.05). Van Gieson staining showed that fibrosis developed in all the three myocardial regions to varying degrees. It is concluded that 2D-STI is non-invasive and can be used to assess regional function of myocardium with different blood supply in rats following acute occlusion of the LAD, and can be used as a sensitive and reliable means to follow up the process of left ventricular remodeling.

Mechanical ventilation (MV) with large tidal volumes can increase lung alveolar permeability and initiate inflammatory responses,resulting in ventilator-induced lung injury (VILI).The mechanisms of the injurious effects of MV and the genetic susceptibility remain unclear.VILI-related genes such as cysteine-rich angiogenic inducer 61 (Cyr61)have been demonstrated to play a detrimental role in the aggressive ventilation strategies.In the present study,we investigated the involvement of Cyr61 in the VIM and the underlying mechanism.A549 cells were exposed to cyclic stretch of varying durations and then the mRNA and protein levels of Cyr61 were measured by real-time PCR and Western blotting,respectively.Additionally,after exposure ofA549 cells to cyclic stretch for 5 min to 1 h,the expression levels of nuclear factor kappaB (NF-κB) and IL-8 were detected by ELISA and Western blotting.Thereafter,Cyr61 expression was depressed in A549 cells with the siRNA pGenesill.1-Cyr61-3 before the cyclic stretch,and IL-8 secretion and the activation of NF-κB pathways were probed by ELISA and Western blotting,respectively.Moreover,a NF-κB inhibitor (PDTC) and an activator (TNF) were used before mechanical stretch.Realtime PCR and ELISA were performed to detect the mRNA and protein of IL-8,respectively.The results showed that the mechanical cyclic stretch led to increased Cyr61 expression at mRNA and protein levels in A549 cells.Additionally,cyclic stretch also mobilized NF-κB from the cytoplasm to the nucleus and increased IL-8 secretion in A549 cells.The inhibition of Cyr61 blocked the NF-κB activation and IL-8 secretion in response to cyclic stretch.Inhibition of NF-κB attenuated the mRNA and protein expression of IL-8 in A549 cells transfected with Cyr61 siRNA.It was suggested that Cyr61/NF-κB signaling pathway mediates the upregulation of IL-8 in response to cyclic stretch in A594 cells.These findings support the hypothesis that Cyr61 plays a critical role in acute lung inflammation triggered by mechanical strain.
