Objective To discuss the nursing intervention effect on reducing anxiety of patients with amputation due to trauma. Methods 30 trauma patients needing amputation were given pertinent nursing intervention according to the psychological problems existing in them by special nurses from admission to operation.Self-rating anxiety scale (SAS)was used to evaluated the anxiety of patients ten minutes after informing them of the operation and ten minutes before the operation.The anxiety level was compared before and after the intervention. Results After the nursing intervention,the level of anxiety was alleviated compared with that on admission. Conclusions Strengthening the nursing intervention can effectively reduce the anxiety level of patients with amputation due to trauma before operation,and improve the initiative and compliance of treatment in patients.

Objective To investigate the effect of BML-111 (the analogue of lipoxin) on uterine Hela cell (cervix cancer cell line) proliferation and the underlying mechanism. Methods Hela cells were stimulated by 50, 100, 200 and 400 μg/L BML-111, respectively, and cell viability was determined by MTT assay. Hela cells were divided into three groups:the control group (no treatment), the BML-111(200μg/L) group and the BML-111(200μg/L)plus Boc-2 (10μmol/L)group. Expression and location of P53 protein were detected by immunofluorescence. Expressions of NF-κB p65,P53 and CyclinD1 protein were detected by Western blotting. Results BML-111 (100, 200 and 400 μg/L) could effectively inhibit Hela cell viability compared with the control group (P < 0.05). P53 expression was shown decreased in both the nucleus and the cytoplasm without any change of P53 location , however, Boc-2 could reverse this effect. BML-111 could effectively inhibit P53 and CyclinD1 expression via NF-κB pathway and the effects could also be inhibited by Boc-2. Conclusions BML-111 can effectively inhibit Hela cell proliferation via FPR2 and NF-κB pathway.

Objective To explore the prospects for applying a brain-computer interface system in the reha-bilitation of dyskinesia by testing the brain-electricity signals of spinal cord injury patients and stroke patients during motor imagery. Methods The brain-electricity signals of 5 healthy people, 4 spinal cord injury patients and 2 stroke patients were tested during motor imagery, and the results were analyzed with a computer. Results All of the 5 healthy people showed event-related synchronization and desynchronization (ERS/ERD) in the α and β bands in the motor related cortex. Three of the 4 spinal cord injury patents showed similar characteristics, and 1 showed ob-vious and stable characteristics, but the 2 stroke patients did not show meaningful characteristics. Conclusions Spinal cord injury patients have brain-electrlcity characteristics similar to those of healthy people when they are expe-riencing motor imagery, whilst in the affected hemisphere of stroke patients the brain-electricity characteristics are not similar to those of healthy people.

A method was developed for the quantification of human growth hormone ( hGH ) by protein purification and isotope dilution-high performance liquid chromatography mass spectrometry ( HPLC-IDMS ) . The hGH was purified and fractionated by fast protein liquid chromatography ( FPLC ) , then hGH molecular weight was accurately determined by Fourier transform ion cyclotron resonance mass spectrometer ( FTICR-MS). The purified hGH was hydrolyzed and the separation was performed on an KINETEX C18 column (150 mmí2 mm I. D. , 2. 6 μm) with water ( containing 0. 1% TFA) and acetonitrile isocratic solution as the mobile phase at a flow rate of 0 . 2 mL/min and 40℃. The electrospray source was operated in the positive ion mode, and monitored in the multiple reaction monitoring ( MRM) mode. The measured hGH molecular weight by FTICR-MS was only 0. 31 Da difference from theoretical value. Three amino ( proline, valine and phenylalanine) were clearly separated by isocratic elution within 5 min. Under the optimized conditions, the content of hGH was 186 . 80 μg/g with a RSD of 0 . 5%. The detection results of hGH in international comparison by this method were consistent with the reference value, which validated the feasibility of the established method. The developed method is simple, practical, accurate, reliable and reproducible, and can be used for the hGH quantitation of pure hGH CRM to provide reference for the routine detection of hGH.
