Objective:To explore the relationship between guilt and shame among middle school students.Methods:The present study investigated 1000 middle school students using Guilt and Shame Events Ques- tionnaire.In-depth interview was administered to 24 students simultaneously.Results:(1)The degree of guilt(6.0?1.2)was higher than the degree of shame(5.0?1.7)in guilt events and the degree of guilt(5.1?1.9)was lower than the degree of shame(5.7?1.4)in shame events(P

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 investigate the incidence and relevant factors of upper gastrointestinal bleeding(UGB)in patients with coronary heart disease(CHD)undergoing dual antiplatelet therapy(DAT)with aspirin plus clopidogrel.Methods A total of 391 CHD patients treated with aspirin plus clopidogrel (DAT group)and 502 control CHD patients receiving single antiplatelet therapy(SAT)with aspirin or clopidogrel(SAT group)were enrolled.The incidence and relevant factors associated with UGB were retrospectively analyzed in both groups of patients.Data were analyzed with Chi-square test and logistic regression by using SAS software version 9.0.Results The incidence of UGB in DAT group was significantly higher compared with SAT group(7.1％ vs.3.4％,P ＜ 0.01).The factors,including DAT,age over 65 years,medication duration over 3 months and previous digestive diseases increased the risk of UGB in CHD patients(P ＜ 0.05),while the use of PPIs(proton-pump inhibitors)or gastric mucosal protectives lowered the risk of UGB(OR:0.415,95％ CI 0.226 ～ 0.762,P =0.0035).Conclusions DAT can significantly increase the risk of UGB.UGB can be increased in elderly CHD patients and those with long-term medication and previous digestive diseases.Utility of PPIs or gastric mucosal protectives can effectively lower the incidence of UGB.

Objective:China was categorized as one of the 68 countdown countries to achieve the United Nations Millennium Development Goals (MDG) 5. This paper aimed to analyze the situation of maternal survival, and coverage of proven cost effective interventions in China, where specific attention was paid to disparities. Methods: National maternal and child mortality surveillance data were used to estimate maternal mortality ratio (MMR). Coverage for proven interventions was analyzed based on National Health Services Survey, where experts' consultations were made for complementation. Results: There had been a significant reduction of MMR in China, however great disparities existed, with rural Ⅱ to Ⅳ areas experiencing 2 to 5 times higher maternal mortality risks than urban areas and accounting for over 70% maternal mortality burdens. Postpartum hemorrhage, pregnancy associated hypertension, embolism and sepsis were the leading causes, and over 75% of the maternal mortality was caused by preventable or curable causes. Maternal health services utilization decreased in accordance with region' s development level. Socioeconomic factors like financial difficulties were the main obstacles hindering access of care.Even those who made deliveries in hospitals faced different probabilities in receiving qualified care according to their socioeconomic standings. Conclusion: China is on track to achieve MDG 5, however great disparities exist. It is necessary to specifically target rural types Ⅱ to Ⅳ areas. Major causes of maternal mortality which can be prevented or averted through the provision of essential obstetrical care. Yet as compared with maternity health needs, insufficient coverage of maternal and child health (MCH) care services and poor service quality are the leading predisposing factors contributing to maternal mortality in China.

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 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.

Objective To evaluate the role of Restriction fragment length polymorphism (RFLP) analysis in detection of the fragment of GEF1α/a gene which are both located at ct and a mating type loci in identification of species, varieties, genotypes and mating types of Cryptococcus neoformans species complex(Cryptococcus neoformans and Cryptococcus gattii). Methods The GEF1α/a gene was selected from 20 genes which both located at α and a mating type loci for RFLP analysis, according to the requirements of sequence similarities and primer design in PCR-RFLP analysis. Primer pair was designed from the conserved regions of GEF1α/a genes of distinct genotypes and mating types of reference strains to amplify a fragment of GEF1α/a gene from Cryptococcus neoformans and Cryptococcns gattii strains tested. Sequence alignment,restriction maps analysis, endonucleases selection and electrophoresis stimulation were conducted by using DNAMAN and Vector NTI software. EeoT14 Ⅰ and Hap Ⅱ endonucleases were selected for RFLP analysis of the GEF1α/a fragments amplified from 125 isolates of Cryptococcns neoformans and Cryptococcus gattii. Results An approximate 1 300 bp fragment was amplified from total 82 Cryptococcus neoformans and 43 Cryptoceccus gattii isolates. However, negative PCR results were found in the reference strains of Cryptococcus laurentii, Candida albicans, Candida tropicalis, Candida parapsilosis, Candida krnsei,Candida glabrata, Trichosporon asahii, Aspergillus fumigatns and Aspergillus flavus. RFLP analysis successfully identified the species, varieties, genotypes and mating types of total 125 isolates of Cryptococcus neoformans and Cryptococcns gattii tested in this study. Condusion PCR-RFLP analysis of the GEF1α/a fragment has the potential value in identification of species, varieties, genotypes and mating types of Cryptococeus neoformans species complex simultaneously and rapidly, and may be a useful tool in molecular epidemiological analysis.

Objective To investigate the efficacy of centrally fixed eyeball for assessment of the depth of anesthesia in premature infants undergoing outpatient fundus examination. Methods Fifty eight premature infants undergoing examination of fundus of eyes were enrolled in this study. Their gestational age (from the first day of last menstruation period to birth) + after birth age (from birth to the day when examination of fundus of eyes was performed) = 44-64 weeks. The patients were randomly divided into 2 groups: Ⅰ group body movement (group M, n = 27) and Ⅱ group centrally fixed eyeball (group E, n = 31). Anesthesia was induced and maintained with isoflurane inhalation. The patients were breathing spontaneously. The eyelids were kept open with speculum after induction of anesthesia. The EC50 of sevoflurane concentration which could inhibit body movement or make eyeballs centrally fixed was determined by up-and-down sequential experiment. The initial isoflurane concentration was 3% in both groups. Each time the isoflurane concentration was increased/decreased by 0.5 %. 95 % confidence interval (CI) was calculated. The lowest SpO2, respiratory rate and coughing during maintenance of anesthesia were recorded. Results The EC50 of sevoflurane (95% CI) was 2.9% (2.2%-3.6%) in group M and 3.4%(2.6%-4.6%) in group E. Examination was successfully completed in all patients. No respiratory depression and coughing occurred during examination and no vomiting and coughing were observed during feeding at 1 h after recovery from anesthesia. No body movement occurred in 15 patients whose eyeballs were centrally fixed in group E. Conclusion Centrally fixed eyeball can be used as sign of appropriate depth of anesthesia for fundus examination in premature infants.
