Objective To investigate the expression of hypoxia inducible factor 1α (HIF-1α) and glucose transporter 1 (GLUT1) in lung adenocarcinoma and its correlation with tumor metastasis. Methods SP immunohistochemistry was used to detect GLUT1 and HIF-1α protein expression in 125 lung adenocarcinoma, including 41 cases without metastasis, 38 cases with lymphatic metastasis and 46 cases with brain metastasis. The correlation of GLUT1 and HIF-1α in lung adenocarcinoma metastasis was analyzed by using x 2 test and Pearson correlation analysis. Results Most lung adenocarcinoma were histologically heterogeneous, which contained more than one adenocarcinoma type. 73.2 % (30/41) cases were acinar predominant adenocarcinoma in lung adenocarcinoma without metastasis; 53.6 % (15/38) cases were acinar predominant adenocarcinoma and 26.3 % (10/38) cases were solid predominant adenocarcinoma in lung adenocarcinoma with lymphatic metastasis; 47.8 % (22/46) cases were papillary predominant adenocarcinoma and 34.8 % (16/46) cases were solid predominant adenocarcinoma in lung adenocarcinoma with brain metastases. The expression level of GLUT1 and HIF-1α in lung adenocarcinoma with lymphatic metastasis group was higher than that of the group without tumor metastasis (P< 0.05); the expression of GLUT1 and HIF-1α were positively correlated (r=0.407, P=0.000). Conclusions Papillary adenocarcinoma is the most histological type in lung adenocarcinoma with brain metastasis, suggesting that papillary adenocarcinoma is more prone to brain metastasis. The expression of GLUT1 and HIF-1α play an important role in lymph node metastasis and brain metastasis of lung adenocarcinoma.

Objective To evaluate the heterozygous ambiguity resolution primers (HARPs) method in resolving ambiguous genotyping results of human leukocyte antigen (HLA) genes in Chinese Hart population, and choose some appropriate HARPs primers. Methods HLA-A, HLA-B and HLA-DRB1 genes of 416 southern Chinese Han individuals were genotyped by sequence-based-typing(SBT) method and then the ambiguous genotyping samples were sequenced again by HARPs primers provided by American Atria company. Results The percentage of ambiguous genotyping samples resolved by HARPs for HLA-A, HLA-B and HLA-DRBI locus was 86.3% (132/153), 73.9% (130/176) and 38.1% (85/223) respectively. Among them, 48.5% (64/132)HLA-A, 80.0% (104/130)HLA-B and all HLA-DRB1(85/85)samples only need one primer, 47.7 % (63/132)HLA-A and 20.0% (26/130)HLA-B samples need two primers. Three to six different HARPs primers can resolve more than 90% ambiguities. Conclusion HARPs is a convenient method and could be a routine method to resolve ambiguities for HLA-A, HLA-B and HLA-DRB1 genes genotyped by SBT in Chinese Han population.

Background Although remarkable progress has been made in microsurgery, surgery of intracranial aneurysm still encounters various complications. Cerebral ischemia and postoperative disorders of nervous system could be induced by various specific operation procedures. To improve the outcomes in intracranial aneurysm surgery and to minimize the occurrence of postoperative ischemic complications, it is necessary to perform real-time monitoring on ischemic damages for the corresponding functional areas. To elevate the sensitivity of Eps changes for the detection of cerebral ischemia induced by operation, we monitored Motion Evoked Potential ( MEPs), Somatosensory Evoked Potential (SSEPs)and Brainstem Auditory Evoked Potential (BAEPs) in microsurgical operations of intracranial aneurysms. And then the correlation between Eps changes and clinical outcome was investigated.Methods MEPs, SSEPs, and BAEPs were recorded intra-operatively for 25 cases in intracranial aneurysms. Monitored results and clinical outcome were analyzed in a prospective observational design.Results The MEPs in 5 of 21 cases, the SSEPs in 5 of 25 cases and the BAEPs in 1 of 3 cases showed inadequate temporary clipping, inadvertent occlusion, inadequate retraction, vasospasm, or compromise to perforating vessels. 3 patients developed advanced weakness, which showed abnormal SSEPs in only one patient while showed abnormal MEPs in all 3 cases.Conclusions The MEPs is more sensitive than SSEPs in monitoring the motor ischemic impairments. The monitoring results were correlated to the clinical outcome closely. Monitoring Eps in keyhole microsurgery of intracranial aneurysms could improve the sensitivity in detecting insufficient distal collateral flow. And then successful completion of potentially hazardous maneuvers would be attained.

To investigate influence of butylphthalide injection on serum neuron specific enolase, C-reactive protein and fatty acid binding protein levels in patients with cerebral vasospasm following aneurysmal subarachnoid hemorrhage.Methods Ninety patients with cerebral vasospasm were admitted to The First Affiliated Hospital of Fujian Medical University, then the patients were divided into two groups: The control group (45 patients) was treated with nimodipine and triple-H therapy after surgery;in addition to nimodipine and triple-H therapy, butylphthalide injection was administered to the experimental group(45 patients).Transcranial doppler(TCD)was used for the evaluating cerebral artery blood flow velocity, and the serum neuron specific enolase(NSE), C-reactive protein(CRP) and fatty acid binding protein(FABP) levels in patients with cerebral vasospasm were measured. Results The experimental group improved significantly more than the control group, a significant decrease in cerebral blood flow velocity of the middle cerebral artery in the experimental group as measured by TCD (P<0.05).The serum levels of NSE, CRP and FABP in the patients in the experimental group decreased more significantly (P<0.05).And the incidence of cerebral infarction in experimental group was lower than that in control group (P<0.05).Conclusion The serum levels of NSE, CRP and FABP in the patients with cerebral vasospasm following aneurysmal subarachnoid hemorrhage could be significantly reduced by administration of butylphthalide injection, which also could improve cerebral blood supply.Therefore, administration of butylphthalide injection is an effective treatment for cerebral vasospasm.

Objective: To study the expression and mechanism of long-chain non-coding RNA PVT1 in tumor by bioinformatics analysis and experimental verification, and to provide new ideas for the study of the pathogenesis of tumors. Methods: The expression of PVT1 in 14 common tumors was downloaded from starBase v2.0 public database, which also was verified by PVT1 RNA-in situ hybridization.The upstream transcription factors, the downstream target microRNA(miRNA) for PVT1 and the target genes for the target miRNAs were predicted and analyzed by using bioinformatics based on the database of UCSC Genome Browser, HMDD v2.0, miRTar Base, JASPAR databases. Results: StarBase database analysis and RNA in situ hybridization showed that PVT1 was highly expressed in kidney clear cell carcinoma and colon and rectal adenocarcinoma. PVT1 was regulated by the upstream transcription factors CREB1, Atf1, SP1, KLF5, STAT3, while it could control the expression of the downstream target miR-16. bcl-2, VEGFA, CCNE1, CCND1 and SHOC2 showed an interaction with the transcription factor of PVT1, which formed a feedback regulatory pathway. Conclusions PVT1 is highly expressed in kidney clear cell carcinoma and colon and rectal adenocarcinoma.The predictive analysis of bioinformatics demonstrates that transcription factor/PVT1/miR-16/target gene signal axon may be an important molecular mechanism, which provide a valuable clue for further functional mechanism research of long-chain non-coding RNA.

OBJECTIVETo evaluate radial artery (RA) and internal mammary artery (IMA) grafts in coronary artery bypass and the use of color Doppler ultrasound in the peri-operative evaluation of IMA and radial-ulnar collateral circulation.

METHODSFrom June 1998 to June 2000, sixty cases of coronary bypass revascularization with RA and IMA were performed. Preoperatively, the radial-ulnar collateral circulation was evaluated with the modified Allen's test, color Doppler ultrasound and noninvasive oxygen saturation measurement. The IMA lumen and blood flow were measured at the first intercostal space with color Doppler ultrasound preoperatively and postoperatively.

RESULTSOne patient (1.7%) died of serious cardiac arrhythmia on the fourth postoperative day. There were no arterial graft harvest related complications. Before harvesting, the ulnar artery blood flow was 30.78 +/- 9.71 ml/min, and it increased to 43.36 +/- 13.98 ml/min (40.87% increase, P < 0.01) after the operation. Compared with the baseline, there was no obvious change of IMA blood flow postoperatively (P > 0.05), but the systolic/diastolic flow ratio markedly decreased from 8.57 +/- 3.98 ml/min to 3.41 +/- 4.87 ml/min (P < 0.01).

CONCLUSIONSArterial grafts can be safely used for coronary bypass revascularization with good results. The ulnar artery blood flow can increase compensatively after RA harvesting. The diastolic blood flow of grafted IMA markedly increased postoperatively. Color Doppler ultrasound was very helpful both in evaluating the radial-ulnar collateral circulation before RA harvesting and in assessing the patency of the grafted IMA after coronary artery bypass grafting (CABG).
