Objective:To investigate the effectiveness of heart rate deceleration capacity (DC) measurement in predicting the car-diotoxicity of malignant tumor patients treated with epirubicin-based chemotherapy. Methods:The clinical medical records, including CK-MB and cTnI levels and dynamic electrocardiogram (ECG) parameters before and after each chemotherapy cycle, of 140 patients treated with epirubicin-based chemotherapy were analyzed. Patients were divided into the DC>4.5 ms group and the DC≤4.5 ms group based on the calculated DC values. The CK-MB and cTnI levels and the dynamic ECG parameters of the two groups were compared af-ter two and four cycles of chemotherapy. Results:Patients in the two groups exhibited no statistically significant difference in their rele-vant clinical and pathological data before receiving chemotherapy (P>0.05). However, after four cycles of chemotherapy, the DC≤4.5 ms group showed a significantly greater increase in serum CK-MB and cTnI concentrations over the pre-chemotherapy levels compared with the DC>4.5 ms group. After two and four cycles of chemotherapy, the DC≤4.5 ms group also exhibited a significantly greater in-crease in mean heart rate (beats/min) and supraventricular and ventricular arrhythmia counts (times/24 h) over the pre-chemotherapy values compared with the DC>4.5 ms group (P<0.05). After four cycles of chemotherapy, 23 cases showed abnormally elevated cTnI levels in the DC≤4.5 ms group. In this group, patients with elevated cTnI level exhibited no statistically significant difference in CK-MB and cTnI concentrations, mean heart rates, and supraventricular and ventricular arrhythmia counts compared with those with nor-mal cTnI level before chemotherapy (P>0.05). However, the DC values of patients with elevated cTnI were significantly lower than those with normal cTnI level (P<0.05). Conclusion:The risk of epirubicin-induced cardiotoxicity increased with decrease in DC value. The DC test was shown to be an effective predictor of the risk of epirubicin-induced cardiotoxicity.

Objective To investigate the effect of dexmedetomidine on minimal induced dose of propofol and cardiovascular responses to tracheal intubation.Methods A double-blind randomized controlled trial was conducted.Sixty patients who underwent elective laparoscopic surgery were randomly divided into the dexmedetomidine group (treatment group) and control group.Patients in treatment group were given dexmedetomidine at dose of 0.1 μg/kg · min for 10 min before anesthesia induction,and then infused with 0.4 μg/kg · h until the end.Sodium chloride injection was infused at the same rate in control group.After 10 minutes from the start of dexmedetomidine or sodium chloride injection,propofol was infused by 0.4 mg/kg · min.The dosage of propofol used was recorded when eyelash reflex disappearing,and BIS value in 40 to 60.Propofol was infusion at the same rate,and laryngoscope was incubated at 2 minutes after fentanyl and rocuronium were given.The alertness/sedation (OAA/S scores),mean arterial pressure (MAP),heart rate,pluse oxygen saturation (SpO2) and BIS values were recorded at baseline (before dexmedetomidine or sodium chloride injection infusion),5 and 10 minutes after dexmedetomidine or sodium chloride injection infusion,at the time of eyelash reflex disappearing,before endotracheal intubation,placing the laryngoscope,1,3 and 5 min after intubation.Results OAA/S scores and BIS values in the treatment group were significantly lower than that of control group at 5 minutes and 10 minutes after the dexmedetomidine or sodium chloride injection infusion(P ＜0.05).MAP in treatment group was higher than that of control group at the time of eyelash reflex disappearing,before endotracheal intubation,placing the laryngoscope,1,3 and 5 minutes after intubation (P ＜0.05).Heart rate in treatment group was lower than that of control group at 5 and 10 minutes after dexmedetomidine or sodium chloride injection infusion and before the endotracheal intubation(P ＜ 0.05).There was no significant difference in terms of SpO2 between two groups (P ＞ 0.05).When patients consciousness disappeared and BIS values were in 40-60,the minimum induced dose of propofol was (88.00 ± 25.91) mg in treatment group and (117.33 ± 25.45) mg in control group.The dosage of propofol treatment group was obviously less than control group (t =4.423,P ＜ 0.05).Conclusion Dexmedetomidine reduces the minimum induced dose of propofol while maintaining more stable hemodynamic changes during anesthesia induction.However,there has no obvious inhibition effect on cardiovascular response to tracheal intubation.

Objectives To investigate the prevalance of quinolone resistance in Laribacter hongkongensis and to evaluate the influence of agar dilution and disc diffusion methods on susceptibility testing for the bacterium. Methods Susceptibility to quinolones of L.hongkongensis was tested by agar dilution and disc diffusion methods. The results for both methods were compared. Results L.hongkongensis isolates exhibited different susceptibility rate for quinolones (levofloxacin>ciprofloxacin>norfloxacin>nalidixic acid). All of the fish isolates were susceptible to levofloxacin and more than 90%were susceptible to ciprofloxacin and Norfloxacin. However,by agar dilution, only 62.50%, 37.50%,48.21%, 19.64%of the frogs isolates were susceptible to levofloxacin, norfloxacin, ciprofloxacin, nalidixic acid, respectively. For fish isolates, comparision of susceptibilities between agar dilution and disc diffusion showed a high (> 95%) percentage agreement for levofloxacin and ciprofloxacin and the highest crepancies were observed with norfloxacin (100%) .But it showed a high discrepancy when comparing the two methods for frogs isolates. Conclusions The resistance rate of L. hongkongens to quinolones was high , especially for frog isolates. The results suggested the use of agar dilution on susceptibility testing for quinolones in L. hongkongensis.

Objective To understand the functional status and radiation protection requirements of helical tomotherapy (TOMO) unit when it is applied in clinic treatment so as to promote the construction of TOMO quality control system.Methods A helical tomotherapy unit with a type of tomotherapy Hi-Art was employed as the radiotherapy unit.A series of tests and analyses on dosimetric and radiation safety performance parameters of the TOMO unit were conducted with the use of a A1SL ionization chamber,a set of solid water equivalent phantoms and other test equipments.The performance parameters were compared with that of a conventional 6 MV accelerator with a type of ARTISTE.Results The deviations of static and dynamic output dose were-1.51％ and 1.18％,respectively.The values of PDD10/PDD1.5 and PDD20/PDD1.5 were 0.608 and 0.318 within the range of X-ray quality parameters calibration.Under the different field conditions of 40 cm × 5 cm,40 cm × 2.5 cm and 40 cm × 1 cm,the stability of transverse/longitudinal dose distribution curve was no more than 1.20％ and the offset distance of Jaw width was smaller than 0.5 mm.Radiation leakage ratio of the treatment rotating center from the muhileaf collimator (MLC) was 0.20％.No matter the average or the maximum value of the leakage radiation from couch plane was less than 0.02％.Conclusions The performances and testing requirements of TOMO unit are different from a conventional electron linear accelerator,the quality control index of TOMO unit should be set seperately and tested strictly in terms of the specific requirements of the unit by complying with the QC programme.The reliable quality control system should be established and effectively implemented to serve the radiotherapy quality and radiation safety effectively in the tomotherapy.

The crystal structural data of TACE, MMP-1, MMP-2, MMP-3 and MMP-9 were obtained from PDB database, and then their catalytic domains' properties including conformation, molecular surface hydrophobicity and electrostatic potential were analyzed and compared by using Insight II molecular modeling software. It was found that the conformation and molecular surface hydrophobicity of catalytic domains of TACE and MMPs were not obviously different, but the molecular surface electrostatic potential of catalytic domain of TACE and MMPs had obvious differences. The findings are helpful in the Rational Drug Design of TACE selective inhibitor.

Objective To determine the involvement of DNA demethylation in tumor necrosis factor-α(TNF-α)-induced matrix metalloproteinase 9 ( MMP9) expression in human epidermal keratinocytes. Methods Real-time RT-PCR, Western blot, and enzyme-linked immuno sorbent assay (ELISA) were performed to determine the mRNA and protein levels of MMP9 after human keratinocyte cell line (HaCaT) cells were treated with 10 ng/ ml TNF-α or 2. 5 μmol/ L DAC/ 300 nmol/ L TSA. Bisulfite sequencing PCR ( BSP) and Methylation-sensitive high-resolution melt analysis ( Ms-HRM) were used to detect significantly differentially demethylated CpG sites in the human MMP9 promoter region in cells exposed to TNF-α. Different sites methylation constructs of promoter-luciferase reporter gene were made to detect the influences of site-specific DNA demethylation on transcription activity of MMP9 promoter. Results Compared with PBS-treated control, TNF-α significantly increased the expression of MMP9 in HaCaT cells for indicated culture duration ( P < 0. 05 ). Real time PCR, Western blot, and ELISA analysis demonstrated that the mRNA and protein levels of MMP9 were increased initially, followed by a decline with prolonged incubation time. After TNF-α treatment, varied degrees of DNA demethylation occurred at 10 CpG sites in the promoter of MMP9, and the changes at the -36 bp site were statistically significant (P<0. 05). The demethylation at the -36 bp site greatly increased the transcription activity of MMP9. Conclusion TNF-α promotes MMP9 expression in HaCaT cells through inducing -36 bp site DNA demethylation on the promoter of MMP9.
