Objective To develop an image analyzing procedure for automatic localization of facial features on infrared images.Methods An unsupervised local and global features extraction method was adopted for the localization of facial features of frontal view face image.First,a threshold was used to segment the image into foreground and background,and the nose was localized by considering the symmetry of the face.Second,Harris operator was adopted to detect interest points in a rectangular area covering all the facial features,and then local maximum of the interest points were detected.And finally,K-means clustering method was used to cluster the points and obtain the facial features localization.Results The experimental result of 100 images demonstrated that the procedure could automatically localize eyes,nose,mouth,and distinguish the feature areas.Conclusion The proposed infrared image analyzing procedure based on Harris operator and K-means clustering can be used to locate facial features on infrared image more rapidly and reliablely.

Objective To describe the early use of nasal continuous positive airway pressure (nCPAP) ventilation for infants presenting acute congestive heart failure (CHF) complicated by congenital heart disease (CHD) and pulmonary artery hypertension (PH).Methods Sixty infants with CHD treated for acute CHF were randomly divided into the nCPAP group (n =32) and the non-nCPAP group (n =28).Data were analyzed,which included lactic acid value (Lac) by arterial blood gas analysis,calculation of oxygenation index [pa (O2)/FiO2],detection of serum N-terminal pro-brain natriuretic peptide of type B (NT-proBNP) level,determination of left ventricular end diastolic volume index (LVEDVI),left ventricular ejection fraction (LVEF) and pulmonary artery systolic pressure (PASP) by noninvasive bedside ultrasonic cardiogram (UCG).Results 1.Comparison of arterial blood gas between the 2 groups:1 d after treatment,there were significant differences in pa (O2)/FiO2 and Lac between the 2 groups (t =4.743,5.402,all P ＜ 0.05).A significant difference was found in the pa (O2)/FiO2 between the nCPAP group and the non-nCPAP group 3-7 d after treatment(t =6.366,P ＜ 0.05).The level of Lac had no significant difference between the 2 groups 3-7 d after treatment(t =1.812,P ＞ 0.05).2.Comparison of index of heart function between the 2 groups:after 3-7 d treatment,LVEDVI,LVEF,and PASP were statistically different between the 2 groups (t =2.052,2.704,2.019,all P ＜0.05).3.Comparison of serum indexes between the 2 groups:3-7 d after treatment,serum NT-proBNP level was improved dramatically compared with the non-nCPAP group(t =9.869,P ＜0.05).4.Comparison of clinical prognosis between the 2 groups:the differences in needing endobronchial intubation rate,mechanical ventilation time,time in PICU and mortality rate were all statistically significant between the 2 groups (x2 =5.505,P =0.019; t =4.788,P =0.000;t =5.068,P =0.000 ;x2 =4.284 ;P =0.038).Conclusions The early use of noninvasive nCPAP for eligible patients with acute CHF complicated by CHD and PH seems to improve their prognosis by improving pa (O2)/FiO2,reducing left ventricular and right ventricular afterload and improving the left ventricular function.

OBJECTIVE: The aim of the study was to evaluate the corelation between an expression of lectins and survival of patients with squamous cell carcinoma of uterine cervix. METHODS: The cell surface carbohydrate profile of formalin-fixed paraffin embedded tissue section of squamous cell carcinoma of the uterine cervix was evaluated using ulex europaeus agglutinin(UEA-1), peanut agglutinin(PNA), dolichos biflorus agglutinin(DBA), soybean agglutinin(SBA) and lotus tetragonobus lectin(LTL) by the avidin-biotin complex method. Fifty-one cases of squamous cell carcinoma and 10 cases of normal squamous epithelium of the uterine cervix were selected from the file which were treated during Jan. 89 to 31 Dec. 1992 in Department of Obstetrics and Gynecology, Korea University Hospital. RESULTS: UEA-1 and LTL were negative in normal cervix while positive in 76.5%, 47.1% of squamous cell carcinoma respectively, and useful markers for differential diagnosis between normal and squamous cell carcinoma. SBA and LTL were useful for differential diagnosis of keratinizing and non-keratinizing squamous cell carcinoma. UEA-1 may play an important role in lymphovascular invasion of squamous cell carcinoma of the uterine cervix. CONCLUSIONS: There was no correlation among clinical staging, patient's survival and lectins binding in squamous cell carcinoma.

Objective: To investigate all trans retinoid Acid (ATRA) inhibition of cell growth in human retinoblastoma Y79 cells, and its mechanism. Methods: Antiproliferation effects of ATRA on Y79 cells were determined by 3 H thymidine incorporation. Cell cycle analysis was performed by flow cytometry. JNK phosphorylation was analyzed by Western blot analysis. Results: After 36 h treatment with 10 -6 mol?L -1 ATRA, 3 H thymidine incorporation decreased to 40%, under the same condition, Y79 cells were arrested in G 0 /G 1 and Sub G 1 peak appeared. Curcumin, JNK blocker, blocked the growth inhibition by ATRA. JNK was phosphorylated in 10 to 20 min. Conclusion: JNK phosphorylating mediated ATRA inhibition of apoptosis in Y79 cells. These results suggested that ATRA might have clinical application for treatment of retinoblastoma.

Results:Body weight of two groups reduced lightly.The blood amylase decreased remarkably.The functions of liver and kidney were recovered gradually.The blood sugar tended to restore normal.Alb,TFN,PAB of two groups increased remarkably( P

Objective To investigate the alteration of phosphorylated GluR1Ser831 and behavioural effects in a rat model of levodopa-induced motor complications after Ca2 +/calmodulin-dependent protein kinase Ⅱ (CaMKⅡ) inhibitor KN-93 treatment. Methods The hemi-parkinsonian rat model was produced by injecting stereotaxically 6-OHDA to right medial forebrain bundle. Then, rats were intraperitoneally treated with levodopa ( 50 mg/kg with benserazide 12.5 mg/kg,twice daily) for 22 days. On day 23 ,rats received KN-93 before levodopa administration. Rotational duration was estimated. After sacrificed, subcellualr distribution of GluR1 and phosphorylated GluR1Ser831 were observed by western blot. Results The study showed that CaMKⅡ inhibitor KN-93 prolonged rotational duration. Moreover, KN-93 could regulate subcellular distribution of GluR1 and reduce hyperphosphorylation of GluR1 Ser831, which was closely associated with levodopa-induced motor complications. The expression of membrane GluR1 and phosphorylated GluR1Ser831 was (83.4 ±4.2)% and (47.2 ±5.2)% ,respectively. Conclusions These results indicated that activation of CaMKⅡ contributed to development of motor complications, through a mechanism that involved an increase in phosphorylated GluR1 Ser831. Pharmaceuticals which act to inhibit CaMKⅡ may be useful in the treatment of the motor complications in parkinsonian patients.

Objective To discuss the effect of daidzein on hepatocellular carcinoma SMMC7721 cell proliferation CD133 expression on tumor stem cell.Methods Hepatocellular carcinoma SMMC7721 cells were cultured,digested and passaged,and divided into six groups with different drug:control group with no daidzein,100 μg/mL daidzein group,200μg/mL daidzein group,300μg/mL daidzein group,400μg/mL daidzein group ,500μg/mL daidzein.The inhibition ratio,hexokinase,alkaline phosphatase and CD133 levels in SMMC7721 cell were detected and compared at 24 h,48 h,72 h among those groups. Results The inhibition ratio was increased by Daidzein dose increasing,and decreased apparently by times extending,especially in 400μg/mL and 500μg/mL daidzeingroups.Compared with control group,the hexokinase and alkaline phosphatase activity and CD133 expression were decreased apparently in groups treated with daidzein(P<0.01).The more the dose,the higher the drop(P<0.01).Conclusion Daidzein can inhibit hepatocellular carcinoma SMMC7721 cell proliferation,and inhibit CD133 expression on tumor stem cell.
