Objective To summarize the experience of diagnosis and treatment of solid-pseudopapillary tumor of pancreas (SPTP).Methods The clinical data of 15 patients with SPTP who were treated in our hospital from March,2003 to March,2006 were analyzed retrospectively.Results The 15 cases were all women, and the average age was 29.4 years.The chief manifestations were abdominal mass, abdominal pain or other abdominal discomfort. None of the 15 cases had history of pancreatitis or abdominal trauma, and no long history of drinking or smoking. Six cases were negative for CEA,CA50,CA199,CA125 and other tumor markers.Solid and solid-cystic masses in pancreas or solid and solid-cystic tumors in retroperitoneum were found both by B-mode ultrasonography and CT examinations. Preoperative fasting blood sugar was within normal limits. The tumor in 8 cases was located in the pancreatic head, in 6 cases was in the body and tail of pancreas, and in 1 case was in the neck of pancreas. The diameter of the tumors was 2.5-10 cm. No metastasis was found in the abdominal cavity or liver. Local excision was performed in 6 cases, distal pancreatectomy was performed in 5 cases, including 2 cases combined with splenectomy, and pancreaticoduodenectomy was performed in 3 cases, segmental pancreatectomy was performed in one patient with tumor in the neck of pancreas. The 15 cases showed typical pathologic manifestation of SPTP by microscopy. At followed up for 16-52 months, no evidence of recurrence or metastasis in these cases was found.Conclusions Solid-pseudopapillary tumor of pancreas primarily affects young women, and it may be located in any part of pancreas. Surgical resection is recommended as the treatment of choice, and the prognosis is good.

Objective To investigate error-related negativity characteristics of patients with internalizing mental disorders and its diagnostic value.Methods Fifty-five patients met with DSM-Ⅳ anxiety or depression criteria were sampled from outpatients and inpatients,and 20 normal adults were selected as control group.With Eriksen and Simon tasks as evoked stimuli,error-related negativities of each participant were acquired using Canada Stellate-64 channel EEG/ERP Instrument and BESA5.2 software,and the data of general information,clinical symptoms,reaction time,and error rate were collected.Results (1) Correct reaction time ((377.5±98.8) ms)and errors reaction time ((337.3±96.6)ms) of patient group were significantly longer than those of control group ((288.5±105.9)ms and (281.9±94.3)ms) on the Eriksen task and Simon task,and there were no significantly group differences on other indicators (P＞0.05).(2) ERN amplitudes at 6 sities (Fz =(4.97±5.74) μV,F3 =(5.50±4.59) μV,F4 =(6.26±6.79) μV,Cz =(4.74±5.51) μV,C3 =(5.44±4.8) μV,C4 =(5.50± 5.28) μV) of patients group were significantly greater than those of control group ((1.17± 1.47)μV,(2.22±3.95) μV,(3.40±2.55)μV,(2.28± 1.41) μV,(3.05±2.47) μV,(3.16±2.51) μV) on the Eriksen task.ERN amplitudes at Fz((5.43±6.61) μV) and F4((6.00±5.50)μV) of patient group were significantly were greater than those of control group ((2.05 ±2.34) μV,(3.09±2.86)μV) on the Simon task,and there were no significantly group differences on the ERN amplitudes at other sites (P＞0.05).(3) ERN latencies ((87.6±34.4) ms and (84.9±34.8) ms) of patient group at Fz and F4 were significantly longer than control group ((54.0±46.5) ms and (36.3±42.4)ms) on the Simon task,and there were no significantly group differences on the ERN latencies at other sites (P＞0.05).Conclusion The increased error related potentials suggest that patients with internalizing mental disorders has an internal error monitoring defects,and ERN might be a useful endophenotype for internalizing mental disorders.

[Objective]To study the clinical features and expressions of IL-17A,IFN-γ,and IL-10 in serum and intestinal mucosa of patients with post-infectious irritable bowel syndrome and non post-infectious irritable bowel syndrome.[Methods]44 diar?rhea-predominate IBS patients(21 with PI-IBS,23 with NPI-IBS)and 10 healthy controls were recruited in this study. Investigation questionnaires of GSRS,SAS,SDS were carried out to evaluate the gastrointestinal function,anxiety status and depression status of IBS patients. The expressions of IL-17A,IFN-γ,and IL-10 in intestinal mucosa and serum were measured by immunohistochemis?try(IHC)and enzyme-linked immunosorbent assay(ELISA).[Results]The SDS scores of NPI-IBS patients were higher than those of controls(P<0.05),and the SAS and SDS scores of PI-IBS patients were higher than those of controls(P<0.05). The GSRS, SAS and SDS scores of PI-IBS group were higher than those of NPI-IBS group(P<0.05). Compared with healthy controls,PI-IBS and NPI-IBS group showed significant rise of IL-17A,IFN-γlevels and decrease of IL-10 level in intestinal mucosa(P<0.05);In serum,the IL-17A levels were up-regulated and the IL-10 levels were decreased in PI-IBS group but not in NPI-IBS group when compared with controls(P<0.05). In intestinal mucosa and serum,IL-17A and IFN-γlevels in PI-IBS group were slightly higher than those in NPI-IBS group(P > 0.05).[Conclusion]PI-IBS and NPI-IBS patients existed various anxiety and depression. The levels of IL-17A and IFN-γ increased and level of IL-10 decreased in PI-IBS and NPI-IBS group. But the clinical symptoms and changes of cytokines of PI-IBS patients were more significant. There may exist other pathogenesis in PI-IBS but not in NPI-IBS.

Objective To investigate the cell cycle and mechanisms of HCC Bel-7404 cell line by treatment of extract of centipede ( ECP). Method Bel-7404 cell line was cultured in vitro. ECP was applied to the interference of the growth of Bel-7404 with different drug concentration. Cell cycles and apoptosis ratios of ECP group were detected by flow cytometry (FCM). To investigate the expression of apop-tosis related genes XIAP and Bax, we also detect HCC Bel-7404 cell line after 48 hours treated with ECP by immunohistochemical method. Result The results of FCM displayed that ECP in treatment group mainly retard cell cycle phase in G0/G1 after 48 hours. The ratios of G0/ G1 .proliferation index (PI) and apoptosis ratios were significantly different between treatment group and control group when the concentrations were different. It was also significantly different between treatment group and control group when the same concentration of ECP was used. It showed that XIAP gene expression decreased gradually while Bax gene expression increased with the increase of ECP concentration, and these were statistical significance in contrast to control group ( P <0.05). Conclusion ECP mainly retarded cell cycle phase of Bel-7404 in G0/G1, suppressed the proliferation, and could induce it to apoptosis. The inhibitory effect was time - concentration dependent. The mechanisms were due to promote Bax gene and inhibit XIAP gene expression in HCC Bel-7404 cell line.

Objective To obtain a single toxin component from the jellyfish Cyanea capillata and provide a foundation for the further study on bioactivity and function of the serine proteases from C.capillata.Methods Primers designed with restriction enzyme were used to amplify the coding region of cDNAs (CcSP1, CcSP2 and CcSP3).PCR fragments were ligated with the pET-24a( +) vector to construct the recombinant plasmids (pET24a-CcSP1, pET24a-CcSP2 and pET24a-CcSP3).After screening and identification,the recombinant plasmids were transformed into the Rosetta (DE3).plysS for protein expression.After induction with IPTG, SDS-PAGE and Western-blot were used to detect the expression of the recombinant proteins.Results SDS-PAGE showed that the proteins of rCcSP1, rCcSP2 and rCcSP3 were expressed in a single band at about 34 kDa, 42 kDa and 42kDa, respectively.Western-blot detection with anti-His antibody further confirmed that these recombinant proteins were His-tagged CcSP1, CcSP2 and CcSP3 fusion protein were obtained.Conclusion Prokaryotic recombinant plasmids of C.capillata serine proteases are contructed and recombinant proteins are obtained, which establishes the foundation for future study on the function of serine proteases from jellyfish.
