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.

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 study the change of substance P(SP) level in Plasma and its relationship with ankylosing spondylitis(AS).Method: Radioimmunoassay. Results: The author observed that the level of SP in Plasma of AS is singificantly higher than that of healthy controls. SP level in AS patients during active stage is higher than in those during inactive stage. Conclusion: Increased SP may play an importantrole in the pathogenesis Of AS.

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 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.

Objective Several previous studies have shown androgens deficiency in men with CHF, and 2 studies on the prognostic significance of serum levels of androgens in CHF patients have yielded conflicting results. The aim of this study was to examine the relationship between serum concentration of testosterone and mortality in men with systolic CHF. Methods A total of 175 elderly (age≥60 years) men with CHF were recruited. Total testosterone (TT) and sex hormone binding globulin (SHBG) were measured, and free serum testosterone (eFT) was calculated. The median follow-up time was 1262 days. Results During follow-up 54 (30.9%) patients died. TT and eFT deficiency was found in 21.7% (38/175) and 27.4% (48/175) patients, respectively. Both TT and eFT were inversely associated with LVEF and NT-proBNP (all P<0.01). Kaplan-Meier curves for patients in low, medium and high tertiles according to TT and eFT level showed significantly different cumulative survival rate (both P<0.01 by log-rank test). However, after adjustment for clinical variables, there were no significant associations between either TT or eFT levels or survival time (OR=0.97, 95% CI, 0.84-1.12, P=0.28; and OR=0.92, 95% CI, 0.82-1.06, P=0.14, respectively). Conclusion Our study showed that although levels of TT and eFT are commonly decreased in elderly patients with systolic CHF and related to disease severity, they are not independent predictors for mortality.

[ ABSTRACT] Diabetes is characterized by an absolute or relative deficiency inβ-cell mass, which cannot be re-versed with existing therapeutic strategies.The restoration of the endogenous islet β-cells can stabilize the level of blood glucose.The isletβ-cells can be obtained from the directional differentiation of stem cells, but the process is complex and has the risk of teratomas generation.Cell direct reprogramming, one terminal differentiated cell can transdifferentiate into another kind of terminal differentiated cell, which is other than directional differentiation from stem cells.Direct reprogram-ming gives rise to the generation of isletβ-cells from one terminal differentiated cell, may be preferable for diabetes therapy because of its unique advantage.

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.
