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 probe into the application of left atrial volume tracking technique(LAVT)on the evaluation of right atrial function in patients with pulmonary hypertension.Methods Forty-one patients with pulmonary hypertension (pulmonary hypertension group) and 37 control subjects (control group) were involved.Right atrial maximal volume (RAVmax),right atrial presystolic volume(RAVpre),right atrial minimal volume (RAVmax),systolic right atrial filling rate (dv/dtS),early diastolic right atrial emptying rate(dv/dtE) and late diastolic right atrial emptying rate(dv/dtA) was derived by LAVT.Right atrial passive emptying volume (RAVp),right atrial passive emptying fraction (RAVpEF),right atrial active emptying volume (RAVa),right atrial active emptying fraction (RAVaEF),right atrial total emptying volume (RAVt)and right atrial total emptying fraction (RAVtEF) was calculated.All the right atrial volume parameter was corrected by body surface area to obtain right atrial volume index (RAVI).Results RAVImax,RAVImin,RAVIpre,RAVIt,RAVIa,dv/dtS and dv/dtA in pulmonary hypertension group was higher than that in control group [(78.39 ± 49.35) ml/m2 vs.(24.80 ± 11.91) ml/m2,(62.59 ± 46.56) ml/m2vs.(17.46 ± 8.40)ml/m2,(70.12 ± 48.03) ml/m2 vs.(20.02 ± 9.46) ml/m2,(18.77 ± 11.47) ml/m2 vs.(9.35 ± 6.74) ml/m2,(8.53 ± 9.81) ml/m2 vs.(3.25 ± 3.00) ml/m2,(145.85 ± 80.56) ml/s vs.(86.44 ± 48.46) ml/s,(155.63 ±126.47) ml/s vs.(67.74 ± 33.27) ml/s],and RAVIp in pulmonary hypertension group was lower than that in control group [(6.09 ± 5.16) ml/m2 vs.(10.23 ± 11.12) ml/m2],and there were significant differences (P ＜0.05).But there were no significant differences in RAVItEF,RAVIpEF,RAVIaEF and dv/dtE between two groups (P＞0.05).Conclusions In patients with pulmonary hypertension,right atrial booster pump function and reservoir function increases,while right atrial conduit function decreases.LAVT has a potential ability to evaluate right atrial function.

Aurora-B as an important kinase to adjust the cell normal mitosis is a potent target for cancer treatment. Aurora-B is overexpressed in a broad range of tumor and tumor cells are more sensitive while Aurora-B is inhibited. Due to the key role of the Aurora-B in cell mitosis, the development of its inhibitors is becoming more and more important. Several small molecules inhibit with a similar efficacy both Aurora-A and Aurora-B, however, in most cases the effects resemble Aurora-B disruption by genetic methods, indicating that Aurora-B represents an effective therapeutic target. There were several Aurora-B kinase inhibitors which had entered the clinics and displayed good antitumor activity. In this review, we will outline the functions of Aurora kinase B in normal cell division and in malignancy. We will focus on recent preclinical and clinical studies that have explored the mechanism of action and clinical effect of Aurora-B inhibitors in cancer treatment.
