Objective: To investigate the applicative value of multislice spiral computed tomography angiography (MSCTA) in the microsurgery of ruptured intracranial aneurysm caused acute intracerebral hematoma. Methods: The imaging and clinical data of 15 patients with ruptured intracranial aneurysm caused intracerebral hematomas, whom underwent emergency surgery after preoperative CT angiography (CTA) were analyzed retrospectively. The surgical plan was determined according to the CTA imaging results. The hematomas were evacuated and the aneurysm were clipped. The applicative value of CTA were evaluated. Results: All the 15 patients were confirmed as intracranial aneurysms in the operation, which was essentially consistent with the preoperative diagnosis by CTA. The size and growth direction of the aneurysms were essentially consistent with the preoperative judgement, and all the aneurysms were clipped. The prognosis of the patients was assessed by the Glasgow Outcome Scale (GOS). All the patients were followed up by the outpatient department and/or telephone for 6 to 78 months (mean 24 months). The GOS score in 2 patients was 2, in 2 was 3, in 6 was 4, and in 5 was 5. Conclusion: Head CTA can briefly and quickly identify the ruptured intracranial aneurysm caused intracerebral hematoma and provide intuitive three-dimensional morphology and anatomical localization of the aneurysms. It is helpful to hematoma evacuation and clipping of the aneurysms in emergency operation.

Objective: To investigate the negative mood status of nurses and patients in different hospitals. Methods: Mood of the nurses and patients from a tumor hospital and a general hospital were assessed with SDS, SAS and by professional assessment with HAMA and HAMD. Results: The rates of anxiety and depression of nurses and patients were both significantly higher than that of the normal group, however, there was no correlation between the bad mood of the patients and the nurses. Negative mood status of the nurses was significantly associated with job stress (r=0.335, 0.392,P

Objective:To optimize the alcohol extraction process of Yiqigutuo granules. Methods: Using the L9 (34 ) orthogonal design method, the active ingredients astragaloside and ferulic acid in the formula were quantitatively analyzed by HPLC. The concen-tration and amount of ethanol, extraction times and extraction duration and the other parameters affecting the extraction volume were ex-amined. Results:Analysis of variance showed that the ethanol concentration and extraction times had significant influence on the ex-tract content and the extraction of ferulic acid. The best alcohol extraction process was as follows:70% ethanol of 10-fold volume, ex-tracting 3 times with 1. 5h for each time. Conclusion:The process is stable, and suitable for the industrial production.

Objective To study and evaluate the therapeutic efficacy of CT-guided radioactive 125Iseeds implantation combined with percutaneous vertebroplasty for spinal vertebra metastases.Methods Fifteen patients and 21 lesions were enrolled in this study.Based on the CT images,a computer-based treatment planning system (TPS) was used to determine the optimal seeds distribution.Under CT-guided,radioactive 125I seeds were implanted into the lesions.Based on the X-ray and CT image after the implantation,quality check was carried out with TPS.The ostalgia-relieving degree and the image alterations of the spinal vertebra metastases lesions were observed.Two months later,15 patients underwent percutaneous vertebroplasty with DSA guidance,bone cement was made according to the ratio methyl acrylic resin polymer/liquid methyl acrylic resin monomer/contrast as 3 ∶ 2 ∶ 1 in injecting paste form.The puncturation through pedicle of vertebral arch and lateral posterior body of vertebra was both adopted in thoracic and lumbosacral vertebrae site.After making sure that the puncturation was completed and there was no leakage in vertebral body,the bone cement was injected into vertebral body quickly.Results Accepted radioactive 125I seeds plantation,relief of pain was obtained.Among 15 patients,8 patients were powerful,6 patients were effective and 1 patient was inefficiency.After treatment,the pain grading significantly decreased.After treatment for 2 months,CT was used to recheck,7 lesions were local controlled,12 lesions had no changes,2 lesions were progress.The responsive rate was 90.5％ (19/21).No serious side-effect happened.Conclusions Radioactive 125I seeds implantation can be a safe and effective method in treating spinal vertebra metastases and obtaining good clinical effects with minimal damage and few complications.Percutaneous vertebroplasty can strengthen the target and relief pain quickly.CT-guided radioactive 125I seeds implantation combined with percutaneous vertebroplasty for the treatment of spinal vertebra metastases has complementary advantages.
