Objective To summarize the clinicopathologic features and treatment outcomes of solid pseudopapillary tumors (SPTs) of the pancreas.Methods Twenty-seven cases of SPT of the pancreas admitted for treatment to the Peking University Cancer Hospital between September 2008 and September 2012 were retrospectively analyzed.Results The majority of the pancreatic SPT patients were young adults (median age: 29 years old) and females (85.2%) .All 27 patients were treated with surgical resection using pancreaticoduodenectomy (n=4) , duodenum preserving pancreatic tumor resection (n=6) , middle pancreatectomy (n=5) , distal pancreatectomy (n=5) , or distal pancreatectomy plus splenectomy (n=7) .The minimum tumor diameter was 1.5 cm, the maximum diameter was 12.0 cm, and the average diameter was 5.4 cm.Twelve patients developed pancreatic leakage and pyrexia following the operation.One patient suffered splenic artery hemorrhage.All 27 patients survived and completed follow-up.Only one patient developed recurrence, which was treated by a second surgical resection, and all other patients showed no clinical signs of recurrence or metastasis.Conclusion SPT of the pancreas has uncertain malignant potential with good prognosis.Radical resection with preservation of the surrounding tissues is an effective and safe treatment for SPT.

Objective To evaluate the effect of this neuroendocrine hormone on protein expression by treating the human dermal fibroblasts with a-melanocyte stimulating hormone (α-MSH ).Methods Thehuman dermal fibroblasts was cultured, and the total protein of the fibroblasts were separated with immobilized pH gradient-based two-dimensional gel electrophoresis (2-DE). After Coomassie bright blue staining, gel images were acquired by Image-scanner and then analyzed with the PDQuest software. 2-DE maps of fibroblasts were established. Partial differently expressed protein spots were incised from gels and digested by trypsin in-gel. Matrix-assisted laser desorption/ionization time of flight mass spectrometry (MALDI-TOF-MS) and MSDB database searching by Mascot? software were used for protein identification. Results Well-resolved, reproducible 2-DE patterns of dermal fibroblasts treated with and without crMSH were obtained. 8 differently expressed protein spots were detected, among which 8 obtained peptide mass fingerprints (PMF) by MALDI-TOF-MS analysis. Among these proteins, of particular interest were five proteins annexin I, HSP27 and lamin A, etc. Conclusions Proteins expressed by human dermal fibroblasts treated with or without crMSH are different, and some of the differently expressed proteins involve apoptosis, intracellular signal transduction and framework construction and so on, which may be associated with anti-fibrosis effects of (a)-MSH on human dermal fibroblasts.

AIM:To observe the protective effect of nicorandil on myocardial ischemia reperfusion injury in patients undergoing valve replacement.METHODS:Sixty patients undergoing valve repalacement were randomly divided into 3 groups:control(Ⅰ)group,nicorandil delayed precondictioning(Ⅱ)group and nicorandil preconditioning(Ⅲ)group.20 mg nicorandil was given i.v.24 h before operation in group Ⅱ,whereas in group Ⅲ,20 mg nicorandil was given i.v.after induction of anesthesia.Blood samples were taken from coronary venous for determination of cTnI,TNF-?,IL-6 levels at aortic clamping(T0),15 min(T1),30 min(T2),60 min(T3),90 min(T4)after aortic declamping.Right atria myocardium tissue were taken at T0 and T2 to observe the histopathological changes with electron microscopy.RESULTS:The levels of cTnI,TNF-?and IL-6 in group Ⅱand Ⅲ were significantly lower than those in group I.Myocardium injury was obviously lighter in groupⅡand Ⅲ than that in group Ⅰ,whereas the levels of cTnI,TNF-?,IL-6 and myocardium injury were lower in group Ⅱ than those in group Ⅲ.CONCLUSION:Nicorandil is effcetive in decreasing myocardial ischemia repefusion injury in patients undergoing valve replacement,The protective effect of nicorandil delayed preconditioning is more obvious than precondictioning.

AIM: To investigate the possible role of nuclear transcription factor kappa B (NF-?B), Bcl-2, Bax and caspase-3 in etodolac-induced apoptosis of liver tumor SMMC7721 cell line. METHODS: Cell apoptosis was determined by flow cytometry analysis with PI staining and DNA laddering. Expression of Bcl-2 and Bax protein was measured by Western blotting. Caspase-3 activity was evaluated by active caspase-3 apoptosis kit with flow cytometry. NF-?B activation was detected by ELISA-based TransAM~(TM) NF-?B p65/p50 kit. RESULTS: Etodolac, a selective COX-2 inhibitor, stimulated apoptosis in liver tumor SMMC7721 cell line significantly. Flow cytometry showed that the apoptotic rate was 16.3%?3.1%, 19.9%?3.6%, 22.9%?3.2%, 31.2%?3.3% with different concentrations of etodolac (0.25, 0.50, 1.0 or 2.0 mmol/L), while the apoptotic peak did not appear in the control group (0 mmol/L) (P

Objective: To explore the therapeutic effects of edaravone, oxiracetam combined with Shuxuetong on cerebral hematoma and improvement of neurological function in patients with cerebral hemorrhage. Methods: A total of 96 patients with cerebral hemorrhage were randomly divided into observation group and control group by the random number table method, with 48 cases in each group.The observation group received intravenous drip of edaravone (4.0g added into 0.9% sodium chloride injection to 250mL, intravenous drip, 1 time/d), oxiracetam(30mg added into 0.9% sodium chloride injection to 100mL solution, 30min intravenous drip, 2 times/d), and Shuxuetong injection(4mL added into 0.9% sodium chloride injection to 250mL, intravenous drip, 1 time/d) on the basis of routine treatment, and the control group was treated with routine treatment for cerebral hemorrhage.The efficacy and safety in the two groups after treatment of 21 days were observed. Results: After treatment, the neurological deficit score and cerebral hematoma volume of the two groups were improved(all P<0.05), but the improvements of the observation group was significantly better than those of the control group[(4.44±3.20)points vs.(10.53±2.86)points, (21.83±3.85)points vs.(26.71±3.49)points, (7.83±5.31)mL vs.(13.74±6.16)mL, t=9.818, 6.506, 5.035, all P<0.01]. The total effective rate of the observation group was higher than that of the control group(87.5% vs.52.1%, χ²=14.740, P<0.05). No drug-related adverse reactions occurred in two groups. Conclusion The application of oxiracetam and edaravone combined with Shuxuetong injection in patients with cerebral hemorrhage can effectively improve the brain edema and nerve defect, it has a positive significance to promote the patients' recovery after cerebral hemorrhage, and it is worthy of clinical application.

Objective To discuss the application of longitudinal reduction of Chinese traditional medicine in surgical treatment of distal radius comminuted fractures in the elderly. Methods Before the operation, the 54 elderly patients with the fracture were reduced by longitudinal direction under anesthesia, then they were treated with minimally invasive plate osteosynthesis in the approach upon the reduction condition and fracture types. Results After 12-month follow-up, the fractures were all healed. The mean healing time of the fractures was 8 weeks (6-12 weeks). At the end of follow -up, the mean range of motion of the wrist was at 50°of flexion, 45°of extension, 30° of ulnar deviation, at 20° of radial deviation. According to the criteria of Gartland and Werley, the results were excellent in 35 cases, good in 17 cases, fair in 2 cases and poor in 0 case. Conclusions It is vital to provide a Chinese traditional longitudinal reduction before invasive surgical plate fixation in treatment of distal radius comminuted fractures, to avoid large-area exposure of fracture site, minimize the damage to the soft tissue, maintain reduction of post operation and achieve good wrist function.

Objective To investigate the clinical value of transient elastography in adult after liver transplantation,by means of evaluating the correlation of liver stiffness measured by FibroScan with liver/renal functions.Method Forty-three patients received orthotopic liver transplant in our hospital during Dec.10,2013 and Mar.19,2014 were included in this study.Liver stiffness measurement (LSM) was performed after transplantation.Clinical data and laboratory tests including liver function and renal function were collected and analyzed.Result Bivariate correlation showed that body mass index (BMI),MELD score,graft-to-recipient weight ratio (GRWR) and warm ischemia time had no correlation with LSM.LSM at the 1st day after transplantation (LSM-1) showed no correlation with cold ischemia time,but LSM at the 7th day after transplantation (LSM-7) did,with R =0.335,P =0.028.LSM-1 showed positive correlation with the ICU time (R =0.488,P =0.001),but LSM-7 didn't.There was significantly positive correlation between LSM and aspartate aminotransferase,bile acid and creatinine,but no significant correlations were found between LSM and alanine arninotransferase,alkaline phosphatase,cholinesterase,gamma-glutamyl transferase,total bilirubin,direct bilirubin,indirect bilirubin,urea nitrogen and uric acid.The group with higher LSM-1 had longer ICU time than the lower group (9 d vs,7 d,P =0.013),and so was the hospital stay (34 d vs.23 d,P =0.023).For the LSM-7,there was no significant difference in ICU time and hospital stay between the two groups.The group with higher LSM-1 had higher serious complication incidence than the lower group (78.57％ vs.27.59％,P =0.002),but the two groups in LSM-7 showed no significant difference in serious complication incidence.Conclusion The LSM partially correlates with the liver function and renal function of liver transplantation recipient,and may have its clinical value for assessing the early prognosis after liver transplantation.
