Kaposiform hemangioendothelioma ( KHE ) is a vascular tumor characterized by intermediate malignancy.Retrospective analysis and literature review on the clinical pathologic,immunohistochemical and clini-cal data of a patient with mesentery KHE.The cardinal symptom of this patient is alimentary track hemorrhage, imageological diagnosed as a huge soft tissue mass of mesentery and invaded ileum.Clinical feature is without Ka-sabach-Merritt phenomenon,observing under the light microscope.The tumor is with cavernous vascular structure, and lymphocyte infiltration inside of stroma.The nodules are composed of disposed and lots of short spindle cell tumor;the tumor cells inside of the nodules are vertical and horizontal staggered and form tendon like or fissuring vessels.Immunohistochemistry:CD31(+),CD34(+),D2-40(+),C-Kit(-),SMA(-),Ki-67(1%).

Objective To investigate the modulation of EPCs by interleukin 1β (IL-1β) and p38 mitogen activated protein kinase (p38MAPK) and the pathogenesis resulting from their dysdifferenfiation after trauma.Method Thirty pigs were divided into a control group (n = 15) and a multiple organ dysfimction syndrome (MODS) group (n = 15), the latter of which were subjected to a "two-hit" injury including hemon'hagic shock and endotoxemia. Phosphorylation of p38MAPK in peripheral blood mononuclear cells was monitored by western blotting. The concentration of IL-1β in peripheral blood plasma was determined by ELISA and the numbers of EPCs with FCM in peripheral blood plasma were monitored. The morbidity rates in the two groups were compared by chi square test. The levels of phosphorylation of p38MAPK in peripheral blood mononuclear cells, the concentmtions of IL-1β in peripheral blood plasma and the numbers of EPCs in the peripheral blood were compared between groups using with Student's t lest. Results The level of p38MAPK phosphorylation was more augmented and the concen-tration of IL-1β higher in peripheral blood mononuelear cells and plasma from MODS pigs compared with those from control pigs; nevertheless the mauler of EPC conspicuously decreased in the peripheral blood (P <0.01). The morbidity rate in the MODS group was much higher than that in the control group (P < 0.01). There were fewer EPCs in the peripheral blood of animals in group M than in the peripheral blood of animals in group C (P <0.01). Conclusions p38MAPK phosphorylation is important for the pathogenesis of MODS. p38MAPK phospho-rylation might cause the concentration of IL-1β in the peripheral blood plasma to rise and could cause a drop in the numbers of EPCs, thereby aggravating the inflanmmatory reaction in MODS.

Objective To explore the expression of Her-2 and the effect on the initiation,development,invasion and metastasis of pancreatic carcinoma.Methods A total of 225 patients with pancreatic carcinomafrom January 2000 to December 2007 were analyzed retrospectively.Paraffin sections of surgical specimens from all the patients who underwent standard resection were examined by SP immunohistochemical method staining.The expression of Her-2 in patients with pancreatic carcinoma and the association between Her-2 and other clinical and pathological parameters were examined.Results Her-2 was positive in 87 of all the 225 patients(38.67%).The differentiation of tumors;size of tumors;lymph node metastasis and other organs metastasis were significantly related to Her-2.The surrival time of the Her-2-positive patients[(19.33±8.15)/nonths]Was significantly shorter than that of the Her-2-negative patients [(36.23±15.44)months]in the univariate analysis(P<0.01).At multivariate COX proportional hagards model analysis,the positivity of Her-2 applied to be an independent prognostic factor,which was also influenced by size of tumors;lymph node metastasis and other organs metastasis.Conclusion It suggests the incidence of Her-2 play an important role in evaluation of the prognosis of pancreatic carcinoma,and it could serve as an independent predictor of prognosis of pancreatic carcinoma.

Objective To analyze the methods and strategy of treatment for multiple injuries in the use of damage control operation, and improve the treatment level and cure rate for multiple injuries.Method From March 2005 to March 2009, 21 patients with multiple injuries were treated by damage control strategy and performed the determinacy operation after the resuscitation in ICU. Results In 21 patients, 16 cases (76.2%) were cured and 5 cases (23.8%) were dead. The injury severity score of 5 dead cases were exceeded 35 points. Conclusions In the strategy of damage control operation, the surgical operation is considered to be a part of the total resuscitative procedure, not the ending of treatment. To those multiple injuries patients, it is safe and effective to perform the damage control operation. It has practical value in clinical treatment.

Objective To analyze the clinic pathologic factors and survival rate by performing a retro-spective study on the early gastric carcinoma (EGC)with signet ring cell underwent curative gastrostomy (SRC) percentage less than 50%after operation .Methods A total of 424 patients was diagnosed as EGC from January 2008 to January 2010 in Changhai Hospital .The patients were divided into three groups according to the different percentage of SRC within tumor cells , SRC group ( with percentage of SCR more than 50%) , Mixed SRC group (with percentage of SRC less than 50%),and Non-SRC group(Classic adenocarcinoma without SRC ).Then we evaluated the clinic pathologic indicators and prognoses , and study on the relationship with histologic types . Results In ECG,the mixed-SRC group was similar to the SRC group on the phases of onset age and sex .On the other phases,the mixed-SRC group was more associated with mucosa -confined,lower lymph node metasta-sis(LNM),and 5-year survival rate was better than adenocarcinoma group (P<0.05).However,the mixed-SRC group showed more submucosal invasion ,and higher LNM than other groups ( P<0 .05 ) .The mixed-SRC component was one of the independent risk factors of LNM .Conclusion In EGC,mixed-SRC had a more favor-able risk factor of LNM ,showed more aggressive behavior than other groups and displayed poor prognosis .

Objective:To investigate the clinical efficacy of pancreaticoduodenectomy with TRIANGLE operation in the treatment of pancreatic head cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 51 patients with pancreatic head cancer who were admitted to the Sichuan Provincial People′s Hospital, Affiliated Hospital of School of Medicine of University of Electronic Science and Technology of China from January 2017 to July 2018 were collected. There were 33 males and 18 females, aged from 42 to 74 years, with a median age of 56 years. Of the 51 patients, 24 cases undergoing standard pancreaticoduodenectomy, in which No.12, 13 and 17 lymph nodes were dissected, combined with transcatheter arterial infusion chemo-therapy (TAI) were allocated into the standard group, and 27 cases undergoing pancreaticoduo-denectomy with TRIANGLE operation, in which No.7, 8, 9, 12, 13, 16, 17 lymph nodes were dissected, combined with TAI were allocated into the TRIANGLE group, respectively. Observation indicators: (1) intraoperative conditions of the two groups; (2) postoperative conditions of the two groups; (3) follow-up and survival. Follow-up was conducted using outpatient examination and telephone interview once three months to detect tumor recurrence and metastasis and survival of patients up to July 2021 or the death of patient. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was analyzed using the chi-square test or the Fisher exact probability. Comparison of ordinal data was analyzed using the rank sum test. Kaplan‐Meier method was used to calculate the survival rate and median survival time and draw survival curve. Log‐Rank test was used for survival analysis. Results:(1) Comparison of intraoperative conditions between the two groups. The operation time, volume of intraoperative blood loss, cases with intraoperative blood transfusion were (501±61)minutes, (563±278)mL, 4 in the standard group, versus (556±46)minutes, (489±234)mL, 6 in the TRIANGLE group, respectively. There was a significant difference in the operation time between the two groups ( t=3.62, P<0.05) but there was no significant difference in the volume of intraoperative blood loss or cases with intraoperative blood transfusion between the two groups ( t=1.03, χ2=0.25, P>0.05). (2) Comparison of postoperative conditions between the two groups. Of the 51 patients, 30 had 50 times of postoperative complications, including 18 times of grade Ⅰ complications of Clavien-Dindo classification, 29 times of grade Ⅱ complications of Clavien-Dindo classification, 2 times of grade Ⅲa complications of Clavien-Dindo classification, 1 time of grade Ⅲb complications of Clavien-Dindo classification, respectively. Cases with postoperative complications, cases with delayed gastric emptying, cases without or with pancreatic fistula as class A or class B, cases with biliary fistula, cases with bleeding, cases with diarrhea were 15, 4, 13, 7, 4, 4, 2, 2 in the standard group, versus 15, 6, 14, 10, 3, 4, 1, 3 in the TRIANGLE group, respectively. There was no significant difference in cases with postoperative complications, cases with delayed gastric emptying, cases with pancreatic fistula between the two groups ( χ2=0.16, 0.02, Z=-0.04, P>0.05) and there was no significant difference in cases with biliary fistula, cases with bleeding, cases with diarrhea between the two groups ( P>0.05). Cases with complications as Clavien-Dindo grade Ⅰ, grade Ⅱ, grade Ⅲ were 10, 11, 2 in the standard group, versus 8, 18, 1 in the TRIANGLE group, showing no significant difference between the two groups ( Z=-0.67, P>0.05). The duration of postoperative hospital stay was (23±8)days in both of the standard group and the TRIANGLE group, showing no significant difference between the two groups ( t=0.31, P>0.05). (3) Follow-up and survival. All the 51 patients were followed-up for 6 to 54 months, with a median follow-up time of 17 months. The postoperative 1-year overall survival rate was 75.0% and 81.5% in the standard group and the TRIANGLE group, respectively. The postoperative 3-year overall survival rate was 12.5% and 22.2% in the standard group and the TRIANGLE group, respectively. The median postoperative survival time was 15.00 months (95% confidence interval as 12.63 to 17.37 months) and 21.00 months (95% confidence interval as 15.91 to 19.62 months) in the standard group and the TRIANGLE group, respectively. There was a significant difference in survival of patients between the two groups ( χ2=4.30, P<0.05). Cases with tumor recurrence during post-operative 1 year and 3 year were 9 and 20 in the standard group, versus 6 and 15 in the TRIANGLE group, respectively. There was no significant difference in cases with tumor recurrence during postoperative 1 year between the two groups ( P>0.05) and there was a significant difference in cases with tumor recurrence during postoperative 3 year between the two groups ( P<0.05). Conclusion:Compared with standard pancreaticoduodenectomy, pancreaticoduodenectomy with TRIANGLE operation can prolong the median survival time of patients with pancreatic head cancer without increasing surgical related complications.
