The life safety and quality of life of elderly patients with hip fractures face great threat due to the particularity of fracture site. Elderly patients with hip fracture are often complicated with a variety of basic medical diseases, thus the perioperative management and comprehensive treatment are relatively complex and diverse, and surgical treatment is only one of the links. With the deepening understanding of senile hip fractures, we increasingly realized that the comprehensive management of senile hip fractures should focus on prevention. Combined with the conception and connotation of tertiary-prevention in preventive medicine, this review summarize the common etiology and preventive measures of senile hip fractures, the application of intelligent devices for fall prevention and monitoring, the green channel for hip fracture patient admission, the management mode of the comprehensive geriatric ward based on multi-disciplinary team, the evolution of surgical methods, and the perioperative comprehensive treatments, which in order to provide reference for medical and health workers to reduce the incidence and improve the treatment effects and prognosis of the senile hip fracture via multifaceted and systematic prevention and treatment measures.

Objective:To investigate the mechanism of subjective cognitive decline(SCD)in resting-state by using regional homogeneity(ReHo)and functional connectivity(FC)in SCD patients.Methods:Resting-state functional magnetic resonance imaging(RS-fMRI)was performed in 25 SCD patients and 30 normal controls matched by sex, education and nationality.DPARSFA2.3 and SPM8 software were used to analyze and screen the brain areas with abnormal ReHo values in SCD group, with the posterior cingulated(PCC)/paruneus as seed points for whole-brain FC analysis.Results:Compared with the normal control group, the SCD group showed that ReHo values of right occipital gyrus and left precuneus were increased, and ReHo values of right inferior temporal gyrus, right orbital inferior frontal gyrus and bilateral thalamus were decreased(Voxel level, Alphasim correction, P<0.05). Using PCC/ precuneus as seed voxels, the whole brain functional connectivity analysis showed that the functional connectivity with cerebelum Crus 2 R was increased, and the functional connectivity with right orbital inferior frontal gyrus, left inferior temporal gyrus and temporal pole was reduced(Voxel level, Alphasim correction, all P<0.05). Conclusions:Default mode network may play an important role in the mechanism of SCD, and abnormalities in brain areas may first occur in PCC/precuneus.

Objective:To investigate regional homogeneity(ReHo)and whole brain functional connectivity(FC)in patients with mild cognitive impairment(MCI), and to explore the mechanisms of MCI in the resting state.Methods:Resting-state functional magnetic resonance imaging(RS-fMRI)was performed on 24 patients with MCI and 30 age, gender and nationality-matched normal controls.Abnormal brain areas in the MCI group were screened and analyzed by using the DPARSFA2.3 and SPM8 software programs.Whole brain FC analysis was performed with the posterior cingulate cortex(PCC)/precuneus as the seed points.Results:Compared with the control group, MCI subjects displayed higher ReHo values in the frontal-middle-Left, precentral-Left, postcentral-Left, rolandic-opercular-Left, and frontal-inferior-opercular-Left and lower ReHo values in the temporal-superior-right, temporal-middle-right, postcentral-right, and temporal -pole -superior -right(Voxel level, Alphasim correction, P<0.05). Whole brain FC analysis showed greater functional connectivity of PCC/precuneus with fusiform-right, thalamus-right, lingual-right and parahippocampal-right in subjects with MCI, and less functional connectivity of the PCC/precuneus with temporal-middle-Left, angular-Left, temporal-superior-Left and occipital-middle-Left in subjects with MCI(Voxel level, Alphasim correction, P<0.05). Conclusions:Abnormalities of the default mode network may be associated with the onset of MCI, and abnormalities in posterior cingulate/precuneus connectivity may be helpful in finding imaging evidence with high sensitivity to MCI.

Objective To explore the gray matter changes in aggressive patients with schizophrenia,and the relationship between the gray matter and aggression in patients.Methods Eighteen aggressive patients with schizophrenia (SZ1),18 age-and gender-matched un-aggressive patients with schizophrenia (SZ2) and 18 normal controls (NC) were enrolled in the study.Then a 3.0 T magnetic resonance imaging (MRI) scan was conducted for each participant.The voxel-based morphometry (VBM) approach and the Chinese version of Buss & Perry aggression questionnaire (B&P) were used to explore imaging data and to assess the aggression,respectively.Results Compared with NC,patients with schizophrenia showed changes in gray matter volume (GMV) in the frontal,temporal and the occipital lobes (P＜0.05,AlphaSim corrected).Compared with SZ2,SZ1 showed increased GMV in the right supramarginal gyrus,right postcentral gyms,bilateral insula and orbito-frontal gyri (P＜0.05,AlphaSim corrected).The GMV of the right insula,right postcentral gyms and right supramarginal grus were positively associated with B&P scores in patients with schizophrenia (P＜0.01,AlphaSim corrected),respectively.Conclusions These preliminary findings support that the aggression in schizophrenia is associated with GMV changes of brain regions in patients with schizophrenia.The right postcentral gyrus,the right insula and the right supramarginal gyrus may be involved in the neural mechanism of aggression in schizophrenia.

Objective To investigate the event-related potentials( ERPs) characters of implicit cog-nitive basis in patients with alcohol dependence(AD). Methods Implicit association task and ERPs were detected in 30 individuals with alcohol dependence and 30 controls. Results In patients group,it revealed interaction between picture type and attitude words(F(1,29)= 32.08, P=0.003),and RTs to alcohol-related picture-positive words((653.2±42.3)ms and RTs to non-alcohol-related picture-negative words((698.5±38. 1)ms) were faster than those of non-alcohol-related picture-positive words((680.2±40.1)ms) and alcohol-related picture-negative words((713.3±43.3)ms).Additionally,the main effects of picture type and attitude words was significant.RTs to alcohol-related picture were faster than those to non-alcohol-related picture. RTs to alcohol-related picture-positive words in patient group were faster than those of controls((710.0±32.3) ms, P=0.009).In patients group,it revealed interaction between P3 amplitudes for picture type and attitude words.P3 amplitudes to alcohol-related picture-positive words were higher than those of P3 amplitudes to al-cohol-related picture-negative words. Interaction among picture type, attitude words and electrode sites was significant in patient group. Conclusions Patients with alcohol dependence present implicit cognitive basis to alcohol related information,and front,front-central and central are neurophysiological architecture.
