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 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 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.

CK.Efficiency of Myo decreases apparently after heart accident onset is more than 6 hours.Traditional marker,CK,CK-MB,AST,LDH and HBDH still have some efficiency in AMI diagnosis.

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: 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.
