Continuity of the polytope generated by a set of matrices is dealt with in this paper. We have defined a norm for the polytope, and verified when these matrices belong to a compact set in R the norm is bounded and the polytope is ***, we have verified if the polytope is treated as a set-valued mapping from R to R, it is continuous and with convex and compact values.

OBJECTIVE To explore the relationship between multimarker detection of MAGE-1,MAGE-3 and AFP mRNAs in the peripheral blood of patients with hepatocellular carcinoma and micrometastasis using a realtime quantitative-PCR(real-time Q-PCR)assay. METHODS Peripheral blood samples were obtained from control subjects and 86 patients with hepatocellular carcinoma (HCC).Real-time Q-PCR was used to detect MAGE-1,MAGE-3, and AFP mRNAs in the blood cells. RESULTS In 86 tumor specimens,the positivity for MAGE-1, MAGE-3,and AFP genes was respectively 34.9%(30/86),60.5% (52/86)and 69.8%(60/86).All specimens expressed at least one ***-1,MAGE-3,and AFP transcripts were detected respectively in 12(14.0%),18(20.1%)and 29(33.7%)of the 86 blood specimens from hepatocellular carcinoma patients,while 45 specimens(52.3%)were positive for at least one *** addition,MAGE-1,MAGE-3 and AFP gene transcripts were not detected in any peripheral blood specimens from 25 chronic liver disease patients and 28 normal healthy *** positive rate correlated with the TNM clinical stages,extrahepatic metastasis and portal vein carcinothrombosis(P<0.05).No correlation was found between tumor size,tumor number, differentiation,serum a-fetoprotein(AFP)and the positive rate. CONCLUSION Our results indicate that a multimarker real- time Q-PCR assay with cancer-specific markers such as MAGE-1 and MAGE-3 in combination with a hepatocyte-specific AFP marker may be a promising diagnostic tool for monitoring hepatocellular carcinoma patients with better sensitivity and specificity.

Background:Sevoflurane has a lot of optimal character such as a lower blood/gas partition coefficient,less irritation to the airway,less toxicity the heart,liver and kidney,so it is well accepted by pediatric anesthesiologists for general anesthesia in *** sevoflurane may be associated with a significant proportion of preschool children’ severe emergence agitation（EA） after aneshthesia. Objectives:The aim of the present study was to assess the effect of remifentanil（REM） administered during the surgery on the incidence and severity of EA in preschool-aged children undergoing sevoflurane general anesthesia. Medthods:Sixty preschool-aged（3-7 years old） children（American Society of Anesthesiologists[ASAI or II]） scheduled for adenotonsillectomy were enrolled in this randomized double-blind study. These children were randomly divided into two groups:sevoflurane/REM group and sevofluranen group. Each child was intramuscular injected atropine before entering into the operating room. Anesthesia was induced with a bolus injection of 3μg/kg fentanyl and 2.5mg/kg propofol. Endotracheal intubation was facilitated by 0.1mg/kg vecuronium. All the patients were ventilated with 50% nitrous oxide in oxygen to maintain an end-tidal CO2 of 35±4mmHg monitoring by end-tidal gas measurement.（volume-controlled ventilation: tidal volume 10ml/kg,respiratory rate 15 times/min）. For anesthesia maintenance, children were randomized to sevoflurane group:inhalation of sevoflurane 1.5%-2.5% and sevoflurane/REM group: inhalation of sevoflurane 1.5%-2.5% and at the same time infusion of 0.1μg/kg/min REM. Two observers who were blind to the trial recorded BP, HR, SpO2,eye-open time and extubation time during operating room. Another two nurses accessed the incidence and severity of EA by Ramsay sedation scales and Pediatric Anesthesia Emergence Delirium scale（PAEDs） in recovery time. Result: We observed that the eye-open time, extubation time, intraoperative hemodynamic datas of two groups
