OBJECTIVETo explore clinical effects of internal fixation in treating displaced clavicle fracture combined with coracoid process.
METHODSFrom January 2005 to July 2012, 9 patients with displaced clavicle fracture combined with coracoid process were treated by internal fixation. Among them, there were 6 males and 3 females with an average age of 40.1 (ranged from 20 to 57) years old. According to Eyres classification: 3 cases were type II B, 1 case was type II A, 3 cases were type III B, and 2 cases were type V A. All patients had history of injury, and diagnosed as coracoid fracture X-ray and CT before operation. Herscovici criteria was used to evaluate function of shoulders joint after operation.
RESULTSSeven of 9 patients were followed up from 6 to 18 (averaged 11) months. The incisions were healed at stage I, coracoid process obtained bony healing, and reduction of acromioclavicular joint well. According to Herscovici criteria, 6 patients got excellent results and 1 in good.
CONCLUSIONInternal fixation for the treatment of displaced clavicle fracture combined with coracoid process could restore physiological anatomical position of coracoid process, and benefit for recovery of limb function.

Objective:To study whether the orientation behavior of rats is affected by multi-sensory information.Methods: SD rats were randomly divided into 2 groups:the audio-visual integration group and pure audio group.The orientation behaviors of rats were observed after given single modal and multi-modal sensory cues with spatial disparities.Results:We found that when the temporal and spatial audio cues were coincident to a target visual cue,the rats had a markedly reduced reaction time and increased success rate in orientation behaviors;there was an obvious audio-visual integration effect.The integration effect was more obvious when the intensity of target visual cue was weak,with the enhancement efficiency being(87.3?8.5)%, significantly higher than that when the intensity of target visual cue was stronger(27.6%,P

Objective To establish the 2 day-old SD rats model of periventricular leukomalacia(PVL).Methods Sixty-five healthy 2 day-old SD rats were randomly divided into 3 experimental PVL groups and 3 control groups.The experimental PVL groups were subjected to right carotid ligation(RCL),and then they were suffered from hypoxia by 6% oxygen and 94% nitrogen for 4 hours.Meanwhile sham surgeries were performed on control groups without exposed to hypoxia.Light and electronic microscopy were used to observe brain pathological changes.Immunohistochemistry methods were used to detect the distribution and expression of glial fibrillary acidic protein(GFAP),?-amyloid precursor protein(?-APP),myelin basie protein(MBP) and O4 of brain at 72 hours post-operation.Han-(ging) test,inclined plane test,open field test and cylinder test were performed on the rats 28 days post-operation.Results 1.In the PVL groups,light and electronic microscopy showed that tissue necrosis was observed in the periventricular white matter area at early stage,and at later stage right ventricular dilation,decrease of the corpus callosum area and loss of medullary sheath were detected.The morphometrical analysis showed that GFAP and ?-APP integrated optical density(A) of PVL group was increased,and mean diameter of GFAP-immunoreactive cells was also increased in PVL group,while MBP A of PVL group was decreased compared with contral group.The density of O4-immunoreactive abnormal cells was dramatically increased in PVL group.The outcomes of neurobehavioral tests of PVL group were greatly abnormal compared with control group.Conclusion The changes in 2-day-old SD rats,RCL-hypoxia model are accor-(ded) with the pathology and behavior characeriatis of PVL.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.

OBJECTIVEThis study aimed to explore the scene-trait coping style of military rescuers in Wenchuan earthquake in an effort to provide scientific evidences for mental intervention program for Chinese military personnel.
METHODSBy cluster sampling, a total of 151 military rescuers and 331 control servicemen were administered the military personnel scene-trait coping style scale (MPSTCSS).
RESULTSAll active coping factor scores, and passive coping factor scores of affection, health and economy in the rescuer group were significantly higher than those in control group (P < 0.05). The 21-above age subgroup, the 3-year plus service subgroup, and the officer subgroup had significantly higher active coping factor scores on military tasks, military experience and personal development than those of the 21-below age subgroup, 3-year minus service subgroup and the soldier subgroup, respectively (P < 0.05 or P < 0.01).
CONCLUSIONThe earthquake relief servicemen can cope with stressful situations better than control group by taking active coping style. The officers, servicemen older than 21 years, and servicemen with more service duration than 3 years could usually take active coping style.

Fibroblast growth factor-21 (FGF-21) is an important metabolism regulator, however, whether FGF-21 has effects on cardiovascular remains unclear. In this study, H2O2-induced injury in H9c2 cells was used as a cell model, the anti-apoptosis potential and mechanism of FGF-21 against oxidative injury were evaluated by MTT assay, flow cytometry assay and real-time PCR. The results showed that FGF-21 could increase the cell survival of H2O2-induced injury in H9c2 cells and prevent H9c2 cells from oxidative stress-induced apoptosis. Furthermore, FGF-21 can elevate SOD activity and regulate Bcl-2/Bax expression in H9c2 cells. The results suggest that FGF-21 have protective effect against the H2O2-induced apoptosis in H9c2 cells.
