OBJECTIVETo investigate the feasibility and reliability on the quantitative evaluation of Colles' fracture by multislice CT (MSCT) multiplanner reconstruction (MPR).

METHODSA total of 36 patients with Colles' fracture from July 2011 to July 2014 were investigated in this study. There were 11 males and 25 females with a mean age of (42.5 ± 5.4) years old (ranged 35 to 72 years). All the patients underwent anteroposterior and lateral X-ray films and MSCT scans on wrist joints within 2 days after trauma. Images were sent to the workstation through picture archiving and conserving system (PACS). One associate chief physician independently and respectively measured the dorsal intercalation depth of distal fracture block, palmar angle and dislocation degree of wrist articular surface collapse on anteroposterior and lateral X-ray film and MSCT-MPR. The time interval between the two measurements was 2 weeks. All the data between the first and second measurement on X-ray and MPR and the mean value between the X-ray and MPR was examined with paired t-test. The pearson analyzed their correlation.

RESULTSAmong the 35 cases, 35 cases of palmar angle, 21 cases of intercalation depth and 16 cases of dislocation of wrist articular surface collapse could be measured on both X-ray and MPR. For the above parameters, the first measurement results were (12.5 ± 3.6)°, (4.5 ± 2.1) mm, (3.7 ± 1.6) mm and the second measurement results were (4.8 ± 2.2)°, (6.4 ± 3.6) mm, (2.5 ± 1.2) mm on X-ray films respectively. The first measurement results on MPR were (14.5 ± 5.3)°, (4.2 ± 1.2) mm, (5.7 ± 2.3) mm, and the results were (13.2 ± 2.6)°, (4.7 ± 2.2) mm, (4.6 ± 2.1) mm for the second measurement respectively. The three parameters between the first and second measurement on plain film had statistical difference and low correlation (r = 0.681, 0.640, 0.345, P < 0.05). The data between the first and second measurement on MPR showed that the dislocation degree of wrist articular surface collapse had statistical difference (P < 0.05) and no statistical significance was found for the other two parameters (P > 0.05), with the moderate correlation (r = 0.954, 0.854, 0.642). The three parameters had low or moderate correlation with each other on X-ray (r = 0.454, 0.532, 0.378, P < 0.05), compared with the mean value on MPR.

CONCLUSIONUsing MSCT MPR images may carry on the multiple parameter measurement of Colles fracture, to make quantitative evaluation, and repeated measurement is better reliability.

OBJECTIVETo identify a naturally presented HLA-A2-restricted epitope of MAGE-A3 antigen, FLWGPRALV (MAGE-A3(271 - 279)), on the surface of a human hepatocellular carcinoma (HCC) cell line HLE.

METHODSSynthetic peptide FLWGPRALV, served as positive control target, was analyzed by HPLC and HPLC-ESI-TOF-MSMS, in order to determine its HPLC elution time, mass-spectrometric characteristics and the lowest detection limitation by the two approaches. 3 x 10(9) HLE cells were collected, peptides naturally presented by major histocompatibility complex (MHC) molecules on the cell surface were isolated by mild acid elution, and concentrated by lyophilization, then the mixtures of peptides were fractioned by HPLC. The ingredient ranged from 2 min before the elution time determined by the synthetic peptide to 2 min after that was collected, concentrated by lyophilization, and analyzed by HPLC-ESI-TOF-MSMS, to identify the existence of the MAGE-A3(271 - 279) peptide.

RESULTSThe HPLC-ESI-TOF-MSMS detection provided an evidence for the existence of a doubly charged ion of (m/z)(2) 529.9, which was further analyzed by collision induced dissociation. The doubly charged ion was ultimately identified as the MAGE-A3(271 - 279) peptide, its amino sequence was FLWGPRALV and its molecular weight was 1058.4 Da.

CONCLUSIONSMAGE-A3(271 - 279) epitope could be naturally presented by HLA-A2 molecules to the surface of HCC cell line and MAGE-A3(271 - 279) peptide may have potential immunotherapeutic value in HCC patients.

BACKGROUNDAtypical meningioma accounts for about 4.7% to 7.2% of all kinds of meningiomas, which is invasive with a relatively high recurrence and mortality. The objective of this study was to investigate the clinical manifestations and therapeutic strategies of atypical meningioma.

METHODSA total of 74 patients who underwent surgical treatment and pathologically confirmed for atypical meningioma in Neurosurgery Department of Beijing Tiantan Hospital from January 2003 to December 2008 were enrolled in this study. The characteristics of the tumors as well as therapeutic regimens and follow-up data were reviewed. After surgery, 56 patients underwent radiotherapy. Patients were followed up for about 3.5 years (range, 0.5 - 6.0 years), and 58 patients completed follow-up.

RESULTSOf the 58 patients who completed follow-up, good recovery was found in 30, neurological dysfunction in 15, and death in 13. Of the 58 patients, 21 had recurrent meningioma and 18 underwent a second surgery.

CONCLUSIONSAtypical meningioma is difficult to manage, with a high recurrence rate and poor survival. The extent of tumor resection and histological grade are the key determinants of outcome. Radiation therapy can be used as an adjunctive treatment after total or partial resection.

To discuss the effect of puerarin (Pue) on the proliferation of hypoxia-induced pulmonary artery smooth muscle cells (PASMCs) and discuss whether the extracellular signal PI3K/AKT pathway was involved in the Pue-induced PASMC apoptosis. With the serum starvation group (SD group) as the control group, the MTT colorimetry method, Annexin V-FITC apoptosis detection kit and Western blot were used to detect Pue's effect on apoptosis of rat PASMCs. The protein immunoblot assay was used to detect whether PI3K/AKT pathway was involved in the inhibition of hypoxia-induced PASMC apoptosis process. The results show that under normoxic conditions, Pue had no effect on PASMC apoptosis; Under hypoxia conditions, Pue can inhibit PASMC apoptosis; Under normoxic and hypoxic conditions, Pue had no effect on TNF-α expression. Pue can reverse hypoxia-induced Bcl-2 (P <0.01), up-regulate it and down-regulated Bax (P <0.01). Under normoxic conditions, Pue had no effect on P-AKT expression. Both LY294002 and Pue can inhibit hypoxia-induced Bcl-2, up-regulation of P-AKT expression and down-regulation of Bax expression. Compared with the hypoxia + Pue group or the hypoxia + LY294002 group, the hypoxia + Pue + LY294002 group showed more significantly changes in Bcl-2, Bax, P-AKT expressions. The results show that, Pue can inhibit the hypoxic-induced PASMC apoptosis, which may be regulated through PI3K/AKT pathway.

To discuss the effect of puerarin (Pue) on the proliferation of hypoxia-induced pulmonary artery smooth muscle cells (PASMCs) and discuss whether its mechanism is achieved by regulating reactive oxygen. PASMCs of primarily cultured rats (2-5 generations) were selected in the experiment. MTT, Western blot, FCM and DCFH-DA were used to observe Pue's effect the proliferation of PASMCs. The Western blot was adopted to detect whether ROS participated in Pue's effect in inhibiting PASMC proliferation. The PASMCs were divided into five groups: the normoxia group, the hypoxia group, the hypoxia + Pue group, the hypoxia + Pue + Rotenone group and the hypoxia + Rotenone group, with Rotenone as the ROS blocker. According to the results, under the conditions of normoxia, Pue had no effect on the PASMC proliferation; But, under the conditions of hypoxia, it could inhibit the PASMC proliferation; Under the conditions of normoxia and hypoxia, Pue had no effect on the expression of the tumor necrosis factor-α (TNF-α) among PASMCs, could down-regulate the expression of hypoxia-induced cell cycle protein Cyclin A and proliferative nuclear antigen (PCNA). DCFH-DA proved Pue could reverse ROS rise caused by hypoxia. Both Rotenone and Pue could inhibit the up-regulated expressions of HIF-1α, Cyclin A, PCNA caused by anoxia, with a synergistic effect. The results suggested that Pue could inhibit the hypoxia-induced PASMC proliferation. Its mechanism may be achieved by regulating ROS.
