Gait recognition is a new technology in biometric recognition and medical treatment which has advantages such as long-distance and non-invasiveness. Depending on the differences between different people's walking pos tures, we can recognize individuals by characteristics extracted from the images of walking movement. A complete gait recognition process usually includes gait sequence acquisition, gait detection, feature extracting and recognition. In this paper, the commonly used methods of these four processes are introduced, and feature extraction methods are classified from different multi-angle views. And then the new algorithm of multi-view emerged in recent years is highlighted. In addition, this paper summarizes the existing difficulties of gait recognition, and looks into the future development trends of it.

Objective To explore the value of spectral curve in the differential diagnosis of benign and malignant tumor of the musculoskeletal system.Methods 100 patients with mass of the musculoskeletal system which were found by MRI underwent Dis-covery HD750 Gemstone CT scan ,and the images acquired were processed.Areas with homogenous density which did not contain necrosis,cyst,hemorrhage and calcification were chosen as region of interest(ROI).The optimal Kev on single energy images was selected,then the Kev-CT curve was automatically generated.All 100 patients proved by histological examination were divided into four groups,38 cases were as group A with benign tumor,10 cases as group B with borderline tumor,49 cases as group C with ma-lignant tumor and 3 cases of lipoma(that were analyzed separately since its curve was arc shaped).Average slope rate of every group was calculated according to the formula:K=(HU40keV-HU80keV)/40.Kruskal Wallis test was applied for statistical analysis,P value of less than 0.05 was considered statistical significant.Results The spectral curve of group C was sharply falling type with a mean slope rate of 1.64±1.00,that of group A was gradually falling type with a mean slope rate of 0.75±0.30,and that of group B was 1.34±0.45.The difference of slope rate between group A and C and between A and B were of statistical significance(P<0.05).The spectral curve of 3 lipomas showed arc shaped rising type with a mean slope rate of-2.00.Conclusion Spectral curve is useful in the differential diagnosis of benign and malignant tumor of the musculoskeletal system.Arc shaped curve is a specific sign for tumors containing abundant fat.

Objective To detect the serum levels of epidermal growth factor（EGF）in rheumatoid arthritis（RA）patients,and explore the possible role of EGF in RA.Methods The serum level of EGF was measured by enzyme-linked immunosorbent assay（ELISA）in 38 RA patients diagnosed according to dianostic criteria for RA by American Rheumatism Association and 20 healthy controls.Rheumatoid factor（RF）,erythrocyte sedimentation rate（ESR）and C-creative protein（CRP）were also measured in these 38 RA patients.The relation beween the serum level changes of EGF and the corresponding clinical indexes in the two groups was statistically analyzed.Results Compared with the healthy individuals,the serum EGF levels of RA patients increased significantly（P 0.05）.Compared with simple bone rarefaction patients,the serum levels of EGF increased significantly in the bone erosion patients（P 0.05）.The serum levels of EGF in RA patients had no correlation with RF,ESR and CRP levels（P 0.05）.Conclusion The evident increase of serum EGF level in RA patients,especially in bone erosion patients,suggests that EGF may partly play a role in the pathogenesis of RA.

OBJECTIVE:To provide reference for rational use of drugs in patients with mental disorders. METHODS:In retro-spective investigation,47 386 prescriptions of psychiatric department in our hospital during Sept. 2013 to Aug. 2014 were analyzed statistically. RESULTS:Totally 39 496 cases were enrolled in the 47 386 prescriptions. The median age of patients was 31.42,with male to female ratio of 1:1.07;they were diagnosed as schizophrenia and other mental disorder,accounting for 65.34%,and fol-lowed by mood disorders,accounting for 15.20% . They were mainly given single drug and two-drug use,accounting for 30.80%and 61.68%respectively. Clozapine,quetiapine,risperidone were top 3 prescription drugs in the list of frequency;olanzapine,que-tiapine,risperidone were top 3 drug in the list of consumption sum. Among top 20 psychiatric prescription drugs,there were 7 kinds of drugs for schizophrenia and other psychiatric disorders,3 kinds of drugs for mood disorders. CONCLUSIONS:The use of antipsychotic drugs in our hospital is rational basically.

BACKGROUND:Excessive mechanical stimulation can lead to endoplasmic reticulum stress. Endoplasmic reticulum stress plays an important role in the occurrence and development of degenerative diseases. Caspase-12 is a specific molecule of endoplasmic reticulum stress, and the intensity of endoplasmic reticulum stress can be reflected by caspase-12 expression. OBJECTIVE:To observe the expression rule of Caspase-12 in chondrocytes under the cyclic tensile stress. METHODS:Human chondrocytes were used as test subjects. After group assignment, mechanical loading system was used. The loading group and corresponding Z-ATAD-FMK inhibitor group received 2, 12, 24, 36, and 48 hours of mechanical stimulation. The blank group (0 hour) and the paired Z-ATAD-FMK inhibitor group received the same process as the loading group except the loading. After loading, cel morphology and growth were observed under the microscope. RT-PCR and western blot assay were used to detect the expression changes of caspase-12 gene and protein in each group. RESULTS AND CONCLUSION:(1) Morphological observation results demonstrated that apoptosis appeared at 2 hours after loading, peaked at 24 hours. With prolonged time, cel growth showed the trend along stress, but apoptosis weakened. It is indicated that cyclic tensile stress could make chondrocyte apoptosis. Endoplasmic reticulum stress might be activated. The model of cel s in vitro was established successful y. (2) Caspase-12 gene and protein expression showed consistent trend, and peaked at 24 hours, which showed significant differences as compared with the blank and inhibitor groups (P<0.05). (3) Cyclic tensile stress can induce chondrocyte endoplasmic reticulum stress, and affect caspase-12 expression.

Objective Three soluble materials were used as carrier of recombinant human bone morphogenetic protein-2(rhBMP-2) in order to seek suitable slow-release carrier of rhBMP-2,which induced neogenetic cartilage in canine tracheal autografting segment.Methods 32 mongrel dogs were randomly and equally divided into 4 groups.A five-ring cervical tracheal segment was harvested as the autograft.The materials including dextran,polyvinyl pyrrolidone(PVP) and collagen were respectively combined with equal rhBMP-2 and then injected into the soft tissues between cartilaginous rings of autografts.In addition,without carrier group was used as controls.Then the autografts were heterotopically transplanted into greater omentum.The animals were sacrificed at postoperative 4 weeks,and the postmortem specimens were examined grossly and histologically.Results Cartilage rings of the grafts were partly absorbed in all four groups.New cartilage was induced in the rhBMP-2 injected area in the groups in which PVP or collagen was used as carrier,and more new cartilage was observed in the collagen group.Conclusions PVP and collagen could be sustained as release carriers for rhBMP-2 in tracheal autograft.Collagen is more effective as a carrier than other vehicles and it could enhance the ability of rhBMP-2 inducing cartilage regeneration in tracheal transplantation.

Objective To investigate the safety and efficacy of hydroxychloroquine plus low-molecular-weight hep-arin and glucocorticoids in pregnant women with antiphospholipid syndrome (APS). Methods Clinical data of 12 pregnant women with APS were retrospectively analyzed. Eight patients were APS secondary to connective tissue disease while four were primary APS. Hydroxychloroquine plus low-molecular-weight heparin was employed for the treatment of all the pa-tients,among some of whom undergone combined glucocorticoids therapy. Results All patients underwent a successful de-livery with no abnormalities and are with normal Apgar scores of the babies. No compliations were developed during a follow up of 2-15 months. Conclusion Hydroxychloroquine plus low-molecular-weight heparin and glucocorticoids is safe and effective in treatment of pregnant women with APS, but its clinical value needs further investigate.

Objective To observe the clinical efficacy of needling the three tongue points plus plum-blossom needle in treating aphasia after ischemic stroke. Method Sixty patients with aphasia after ischemic stroke were randomized into a treatment group and a control group, 30 in each group. The treatment group was intervened by needling the three tongue points plus treating the Jiao’s Language Zone 1 with plum-blossom needle, while the control group was by regular body acupuncture. After 2 treatment courses, the language function score (spontaneous speech fluency, repeating, and reading scores) were observed, and the clinical efficacies were compared.Result After intervention, the spontaneous speech fluency, repeating, and reading scores were significantly changed in both groups (P<0.01). After intervention, there were significant differences in comparing the speech fluency, repeating, and reading scores between the two groups (P<0.05). The total effective rate was 86.7% in the treatment group versus 76.7% in the control group, and the difference was statistically significant (P<0.05).Conclusion Needling the three tongue points plus plum- blossom needle is an effective method in treating aphasia after ischemic stroke.
