Objective To compare the one?year survival rates of maintenance hemodialysis (HD) patients with different quality of life, and analyze related factors affecting the prognosis of patients. Methods Patients on hemodialysis for at least 3 months were enrolled. A short form 36 health survey questionnaire (SF?36) and Pittsburgh sleep quality index (PSQI) were used to evaluate the quality of life and quality of sleep. To observe one?year all?cause mortality and Cox regression model was used to analyze the factors associated with survival outcomes. Results A total of 159 patients undergoing hemodialysis were included, in which 136 patients completed the follow?up after one?year observation. The one?year survival rate in patients with both high physical component summary (PCS) and mental component summary (MCS) scores was significantly better than the patients with low PCS and MCS scores (P﹤0.05). PCS, hemoglobin and serum albumin were the protection factors for HD patients. Conclusions Quality of life is strongly associated with prognosis in HD patients. Enhancing quality of life is of clinical significance in the improvement of HD patients' survival rate.

The two isolates were evaluated against CHROM Candida medi um and API 20C AUX. Results The two isolates of Candida rugosa were evaluated as Candida tropicalis by CHROM Candida medium and API 20C AUX. Conclusio ns Discrep ancy between genotype and phenotype of the two clinical isolates of Candida ru gosa was confirmed.

Objective To evaluate the efficacy of Coopdech bronchial blocker combined with a strengthened single-lumen tube for airway management in patients undergoing upper mediastinal tumor resection. Methods Twenty-two ASA Ⅱ or Ⅲ patients, aged 24-66 yr, weighing 48-78 kg, scheduled for elective resection of upper mediastinal tumor, were randomly divided into 2 groups (n=11 each):double-lumen tube group(groupⅠ) and Coopdech bronchial blocker combined with a strengthened single-lumen tube group(group Ⅱ).One-lung ventilation was achieved with a double-lumen tube in groupⅠ. The Coopdech bronchial blocker combined with a strengthened single-lumen tube was used for airway management and the Coopdech bronchial blocker was used for lung isolation when one-lung ventilation was required in group Ⅱ. The fiberoptic bronchoscope was used to assist endotracheal tube positioning in both groups. The intubation time, positioning time, the number of patients required for tube displacement, the number of fiberoptic bronchoscopy, increase in airway peak pressure, degree of lung collapse, postoperative sore throat and hoarseness, and the number of patients needing ventilator-assisted ventilation were recorded. Results The intubation time was significantly shorter, the number of patients required for tube displacement was significantly smaller,and the rate of increase in airway peak pressure and incidences ofpostoperative sore throat and hoarseness were significantly lower in group Ⅱ than in group Ⅰ (P＜0.05 or0.01). Conclusion The efficacy of the Coopdech bronchial blocker combined with a strengthened single-lumen tube for airway management is better in patients undergoing upper mediastinal tumor resection than the double-lumen tube.

Objective To observe the influence of highflux hemodialysis(HFD)on homocysteine(Hcy) level and major cardiovascular events of maintenance hemodialysis (MHD) patients. Methods Patients eligible for inclusion were randomly divided into HFD group and low flux hemodialysis(HD)group with 30 cases in each group. Patient′s serum homocysteine (Hcy),major cardiovascular events and various clinical indicators were observed for 12 months then the data were analyzed. Results Hcy baseline levels in 2 groups(21.02 ± 11.79 mmol/L vs. 19.86 ± 6.97 mmol/L)indicated no significant difference(P = 0.162)before hemodialysis but Hcy levels had significant difference(20.29 ± 11.45 mmol/L vs. 24.57 ± 13.23 mmol/L),(P=0.045)after 12-month observation. There was lower incidence of major cardiovascular events in HFD when compared to that in HD group (10.0% vs. 33.3%) which showed significantly statistical difference (P=0.034),and there was no mortality in HFD group but 1 case of death in HD group. All-cause mortality in 2 groups showed no significant difference (P > 0.05). Conclusion Long-term HFD treatment significantly reduces Hcy levels and the incidence of major cardiovascular events of MHD patients
