The Relationship between College Graduate’s Dual Self-Consciousness and Job Search Clarity: The Mediating Role of Perceived Stress

The aim of the study was to explore the relationship between college graduates’ dual self-consciousness, job search clarity and perceived stress, and reveal the mediating role of perceived stress between dual self-consciousness and job search clarity. In this study, 467 college graduates were investigated using the Dual Self-Consciousness Scale, Job Search Clarity Scale, and Perceived Stress Scale. After controlling for gender, age, and region, the results revealed that: (1) private self-consciousness has a significant positive predictive effect on job search clarity; (2) perceived stress has a significant negative predictive effect on job search clarity; (3) perceived stress plays partial mediation effects between private self-consciousness and job search clarity; (4) perceived stress plays complete mediation effects between public self-consciousness and job search clarity; (5) perceived stress has suppressing effects between public self-consciousness and job search clarity.     

Sex‐related Disparity in Surgical Mortality among Pediatric Patients

Background. It has been reported that gender differences in cardiovascular outcomes found in adults also are present in children who undergo surgical repair for congenital heart disease. Methods. California statewide hospital discharge data 1989–99 were used to study outcomes in children <18 years undergoing cardiac surgery. Hospital discharge data were linked to death registry data to study postdischarge death within 30 days of discharge. We used logistic regression to evaluate the effect of gender on mortality controlling for age, race and ethnicity, type of insurance, household income, date and month of surgery, type of admission, hospital case volume, and various types of procedures. Results. There were 25 402 cardiac surgery cases with 1505 in‐hospital deaths (mortality rate of 5.92%). An additional 37 deaths occurred within 30 days after hospital discharge. Crude mortality rates for males (5.99%) and females (5.84%) were not significantly different. However, fewer neonates were female and females underwent a higher proportion of low‐risk procedures than males. Logistic regression revealed that females, compared with males, had a significantly higher odds ratio (OR) for in‐hospital mortality (OR = 1.18, P < .01) and overall (up to 30 days post discharge) mortality (OR = 1.18, P < .01). The risk‐adjusted length of hospital stay was similar between females and males while charges per hospital day were slightly higher in females than males. The prevalence of Down syndrome, pulmonary hypertension, and failure to thrive were higher in females. Conclusions. Female gender is associated with an 18% higher in‐hospital and 30‐day postdischarge mortality as compared with male gender. There was no difference in length of hospital stay between males and females. The mechanism by which female gender acts as a risk factor requires further investigation.     

吗啡依赖和戒断对大鼠杏仁核神经甾体和氨基酸递质水平的影响

目的研究吗啡依赖和戒断时大鼠杏仁核中神经甾体和氨基酸递质水平的变化。方法连续7天给予大鼠盐酸吗啡建立吗啡依赖模型。使用纳洛酮(2mg/kg)催促戒断,观察戒断症状并进行评分。将大鼠断头处死后,剥离大脑并分离出杏仁核,用液-液萃取和固相萃取法提取游离型和结合型神经甾体。神经甾体(包括脱氢表雄酮、孕烯醇酮、别孕烯醇酮、脱氢表雄酮硫酸酯和孕烯醇酮硫酸酯)的含量使用高效液相色谱-质谱法测定。甘氨酸、谷氨酸和γ-氨基丁酸的含量采用柱前OPA衍生-电化学检测-高效液相色谱法测定。结果与盐水对照组相比,吗啡依赖大鼠杏仁核中的脱氢表雄酮水平降低33 %(P<0·01)。与戒断对照组比较,吗啡戒断大鼠杏仁核中的孕烯醇酮和别孕烯醇酮水平分别升高45 %和42 %(P<0·05) ,γ-氨基丁酸水平降低18 %(P<0·01)。与吗啡依赖组比较,吗啡戒断组大鼠杏仁核中的孕烯醇酮和孕烯醇酮硫酸酯水平分别升高60 %和40 %(P<0·05) ,甘氨酸水平降低14 %(P<0·05)。结论吗啡依赖大鼠杏仁核中的脱氢表雄酮可能参与吗啡依赖的形成而与吗啡戒断症状的表达无关。其他神经甾体(包括孕烯醇酮、别孕烯醇酮和孕烯醇酮硫酸酯)则可能参与吗啡的戒断而与依赖的形成无关。纳洛酮催促戒断时,大鼠杏仁核中抑制性氨基酸递质的合成和释放受到抑制。表明大鼠杏仁核中的各种神经甾体和氨基酸递质在吗啡依赖和戒断时发生了不同的变化。     

皮质发育障碍模型的建立及其致痫敏感性的研究

目的:建立皮质发育障碍模型,探讨皮质发育障碍模型的敏感性。方法:在SD大鼠孕17d腹腔注入1,3-二氯乙烯-亚硝基脲(BCNU)制作皮质发育障碍模型;Nissl染色观察P60d仔鼠病理变化;选取P60d雄性仔鼠,腹腔注射氯化锂-毛果芸香碱,分别比较两组大鼠癫发生的潜伏期、持续状态时间和死亡率。结果:同龄仔鼠脑组织湿重实验组比对照组显著减轻(P<0.01);Nissl染色显示皮质变薄、皮质层次紊乱、海马区域异位细胞异常聚集;有皮质发育障碍的仔鼠注射氯化锂-毛果芸香碱后,癫发生的潜伏期显著缩短(P<0.01),癫持续状态时间延长(P<0.01),死亡率显著升高(P<0.05)。结论:BCNU致皮质发育障碍模型具有癫易感性。     

Prognostic factors for surgical resection in patients with multidrug-resistant tuberculosis.

Although surgical lung resection could improve prognosis in some patients with multidrug-resistant tuberculosis (MDR-TB), there are no reports on the optimal candidates for this surgery. The aim of the present study was to elucidate the prognostic factors for surgery in patients with MDR-TB. Patients who underwent lung resection for the treatment of MDR-TB between March 1993 and December 2004 were included in the present study. Treatment failure was defined as greater than or equal to two of the five cultures recorded in the final 12 months of treatment being positive, any one of the final three cultures being positive, or the patient having died during treatment. The variables that affected treatment outcomes were identified through univariate and multivariate logistic regression analysis. In total, 79 patients with MDR-TB were included in the present study. The treatment outcomes of 22 (27.8%) patients were classified as failure. A body mass index <18.5 kg x m(-2), primary resistance, resistance to ofloxacin and the presence of a cavitary lesion beyond the range of the surgical resection were associated with treatment failure. Low body mass index, primary resistance, resistance to ofloxacin and cavitary lesions beyond the range of resection are possible poor prognostic factors for surgical lung resection in multidrug-resistant tuberculosis patients.
