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.

BACKGROUND: Artesunate can relieve pulmonary fibrosis, but its mechanisms are rarely reported.OBJECTIVE: To explore the effect of artesunate on apoptosis of HFL-I cells and the role of Fas, FasL and Caspase-3 in the artesunate-mediated apoptosis of HFL-I cells. METHODS: Cell counting kit-8 (CCK-8) assay was used to determine the effects of artesunate at 1, 10, 100 mg/L on the growth of HFL-I cells in vitro. Apoptosis ratio was examined by flow cytometry (FCM). The mRNA level of Fas, FasL and Caspase-3, were assessed by reverse transcription-polymerase chain reaction (RT-PCR). RESULTS AND CONCLUSION: Artesunate had a significantly inhibitory effect on the proliferation of HFL-I cells in a dose-dependent manner in vitro. The apoptosis rate of HFL-I cells was significantly increased in the artesunate-treated group compared with the control group (P < 0.05 or P < 0.01). The mRNA levels of Fas, FasL and Caspase-3 were significantly higher in the artesunate-treated group than the control group (P < 0.05). The findings of this study demonstrate that artesunate can exert a marked anti-pulmonary fibrosis effect by up-regulating mRNA levels of Fas, FasL and Caspase-3, which can induce the growth inhibition and apoptosis in HFL-I cells.

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.

Objective To investigate the value of serum ischemia-modified protein (IMA),hypersensitivity C reaction protein (hs-CRP),myoglobin (MYO)creatine kinase MB (CK-MB)and ultra-sensitivity troponin T (hs-cTnT)in the early diagnosis of patients with acute coronary syndrome(ACS).Methods Serum levels of IMA,hs-CRP,MYO,CK-MB and hs-cTnT were meaused in 94 patients with ACS[including 40 cases of unstable angina pectoris(UAP),20 cases of non-ST segment elevation myocardial in-farction(NSTEMI),non-Q wave myocardial infarction and 34 cases of ST segment elevation myocardial infarction(STEMI),Q wave myocardial infarction]and 99 cases of controls.The efficiency,sensitivity,specificity,negative and positive predictive values in the early diagnosis of ACS were compared among 5 kinds markers by the ROC curve.Results The detection results of serum IMA,hs-CRP,MYO,CK-MB and hs-cTnT had statistically significant differences between the UAP,NSTEMI and STEMI groups with the normal control group (P <0.05),serum IMA,hs-CRP,MYO,CK-MB and hs-cTnT had statistically significant differences between the UAP group with the NSTEMI group and between the UAP group with STEMI group (P <0.05),but the difference between NSTEMI and STEMI group group was not statistically significant (P >0.05).Conclusion In the patients with ACS,the multiple indicators combined detection can achieve the early diagnostic value.
