Objective To explore the diagnostic value of axial diffusion tensor imaging(DTI) for gliomas grading at 3 .0T MRI , analyze the characteristics of different grades gliomas of axial DTI in order to improve diagnostic accuracy .Methods A retrospec‐tive analysis was performed involving a group of 37 cases of high grade glioma and 26 cases of low grade glioma confirmed by the pathological results in affiliated hospital of Luzhou medical college ,observation analysis was obtained in axial DTI ,peritumoral neu‐rofibrillary was divided into three types :displacement ,interruption and neurofibrillary tangles(NFT) .Results among the 26 cases of low grade glioma ,there were 18 cases of displacement ;8 cases of interruption ,no NFT ;among the 37 cases of high grade glio‐mas ,there were 9 cases of displacement ,21 cases of interruption ,and 7 cases of NFT (1 case of frontal lobe ,6 cases of temporal lobe);ordinal variables rank sum test in two independent samples between high grade glioma group and low grade glioma showed significant differences(Z= -3 .756 ,P<0 .05);χ2 test showed no significant difference(P>0 .05) ,frontal lobe appeared NFT in 1 case ,accounting for 2 .7% (1/37) ,temporal lobe appeared NFT in 6 cases ,accounting for 16 .2% (6/37) .Conclusion Peritumoral neurofibrillary of the low grade gliomas more performed displacement ,the high grade gliomas show more interrupts and NFT at 3 .0T MRI ,NFT in high grade gliomas is often seen in the temporal and frontal lobe .

Objective To analyze the curative effects and complications of ventriculo-peritoneal shunt in treating hydrocephalus caused by different diseases in children. Methods The data of 289 children with hydrocephalus who were performed ventriculo-peritoneal shunt were examined and the incidence rate of complications was analyzed. Results Thirty-seven incidences of complications occurred in 24 patients with the total incidence rate of 12.46%.There was obstruction of proximate tube in five cases,distal end in two cases,with the obstruction rate of 2.42%.Postoperative infection happened in nine cases(3.11%).Bacterial culture was positive in three cases,two of which were Staphylococcus epidermidis and Bacillus coli in the other one.Negative results were found in six patients for the bacterial culture.Subdural hematoma occured in one case,and tube break after injury in two cases.Slit ventricle syndrome broke out seven times in three cases,leakage of cerebrospinal fluid in two,exposure of pumps in three,and subcutaneous hydrops in two.Four cases(1.38%)were dead from infection. Conclusion Ventriculo-peritoneal shunt is preferred for hydrocephalus in children if the complications are well prevented and controlled.

Objective To investigate the potential role of angiotensinⅡ(AngⅡ)-angiotensinⅡreceptor 1 (ATRI) pathway on inflammatory activation in the lung of rats. Method Twenty four Sprague-Dawley rats were randomly divided into four groups: control group, Ang II group, AngⅡ+losartan group and losartan group. Lung wet/dry weight (W/D) was recorded to assess lung injury. The total lung homogenates were prepared to detect nuclear factor-kappa B (NF-?B) activation by electrophoretic mobility gel shift assary (EMSA), tumor necrosis factor (TNF)-?mRNA expression by reverse transcription polymerase chain reaction (RT-PCR), myeloperoxidase (MPO) and malondialdehyde (MDA) by colorimetry. Plasma yon Willebrand Factor (vWF) were assessed by enzyme-linked immunosorbent assay (ELISA). Meanwhile, pathological changes were examined under optical microscope. Results Histologically, alveolar edema, hemorrhage, and massive inflammatory cell infiltration were observed in AngⅡgroup, but not in control group and losartan group. Compared with AngⅡgroup, histological injury was lesser in AngⅡ+ losartan group. In AngⅡgroup, lung W/D, NF-?B activation, TNF-?mRNA expression, MPO, MDA and vWF were markedly higher than those in the other three groups. There were not significant differences of lung W/D, NF-?B activation, TNF-?mRNA expression, MPO, MDA and vWF in control group, AngⅡ+ losartan group and losartan group. Conclusions Systemic infusion of AngⅡcould up- regulate inflammatory mediator expression and induce lung injury in rats. AngⅡ, acting mainly through ATRI, induced inflammatory activation in the lung of rats.

OBJECTIVETo investigate the clinical characteristics, diagnosis, misdiagnosis and treatment of pelvic vas deferens abscess.
METHODSThe clinical data of one case of pelvic vas deferens abscess were reported and the relevant literature was reviewed.
RESULTSThe patient underwent incision and drainage of pelvic vas deferens abscess. After the catheter was removed, he could urinate easily. With a follow-up of one year, he was found free of dysuria and recurrence.
CONCLUSIONPelvic vas deferens abscess tends to be misdiagnosed when enwrapped. Surgical procedures are the most effective treatment for this disease.

OBJECTIVETo evaluate surgical treatment of obstructing colorectal cancer.
METHODSFrom July 1993 to July 2003, clinical data of 297 cases undergoing emergency operation for obstructing colorectal cancer were analyzed retrospectively. There were 103 cases with right-sided lesion and 194 cases with left- sided lesion.
RESULTSAll patients received emergency operation. Stage i tumor resection and anastomosis were performed in 126 patients including 98 cases with right- sided lesion and 28 with left- sided lesion, total or subtotal colectomy in 108,Hartmann operation in 36,Dixon operation in 9, ileocolic anastomosis in 11,and colostomy in 7 cases.

Objective:To explore the prognosis and risk factors for conversion from off-pump coronary artery bypass grafting (OPCABG) to coronary bypass grafting (CABG) during surgery.
Methods: We retrospectively analyzed 2613 patients with elective OPCAB in our hospital from 2001 to 2012, there were 62 (2.37%) patients converted to CABG during the operation as Conversion group, the rest 2551 patients were set as Non-conversion group. The peril-operative baseline clinical data and prognosis condition were compared between 2 groups. The risk factors causing the in-operative conversion were studied with binary logistic regression analysis.
Results: The total conversion rate was 2.37%, including 42 patients of hemodynamic instability, 6 with dififculty of target vessel exposure, 9 with malignant arrhythmia, 3 with graft occlusion and 2 patients with other reasons. Compared with Non-conversion group, the Conversion group had increased post-operative drainage and ventilation time, higher rates of second thoracotomy for stop bleeding and higher peril-operative mortality. Binary logistic regression analysis indicated that chronic obstructive pulmonary disease, previous history of CABG, NYHA class≥3, LVEF≤40%and left main disease were the independent risk factors for in-operative conversion.
Conclusion: Conversion from OPCAB to CABG during the operation would be result in signiifcantly higher morbidity and mortality in relevant patients.

OBJECTIVETo explore factors affecting occupational adaptability in nurses for offering basis to increase their occupational adaptability.
METHODSFive hundred and forty-five nurses were investigated with work ability index questionnaire and occupational stress instruments.
RESULTSThere were many risk factors affecting occupational adaptability in nurses. The main variables that influenced occupational adaptability included work-overtime, mental load, social support, physical environment, and job hazards. The social support was the factor increasing the occupational adaptability of the nurses (P < 0.01, OR = 0.912). Five factors including work overtime, mental load, social support, physical environment and job hazards were introduced in the Logistic equation. The established functions were: Logit (P) = -11.357 + 1.011x(1) + 0.335x(2) - 0.076x(3) + 0.260x(4) + 0.129x(5).
CONCLUSIONThere are many risk factors affecting occupational adaptability in nurses. Relevant measures should be taken to promote the occupational adaptability in nurses to reduce the risk factors.
