Objective To investigate the influence of oral intake of goop before oral intestinal cleaning drugs on blood glucose,cleansing effect and tolerance of patients.Methods 88 patients who were prepared for intestinal examination or bowel treatment with enteroscope were randomly divided into the food-intake group (group A) and the fasting group (group B) with 44 cases in each group.Group A was given goop 2.5 hours before oral intake of intestinal cleansing drugs,group B fasted before oral intake of intestinal cleansing drugs.Blood glucose was monitored before as well as 6 hours after oral intake of intestinal cleansing drugs.Intestinal cleansing effect was evaluated during intestinal examination or bowel treatment with enteroscope.Cases of patients who ceased intestinal examination or bowel treatment with enteroscope due to intolerance were summarized.The blood glucose,cleansing effect and tolerance of patients were compared between two groups.Results There was significant difference in blood glucose between the two groups before and after oral intake of intestinal cleansing drugs.The cleansing effect showed no significant difference,but the difference of tolerance between two groups was significant.Conclusions Intake of goop 2.5 hours before oral intake of intestinal cleansing drugs does not affects intestinal cleansing effect,and it can obviously increase the blood sugar,improve tolerance of patients,thus ensure the smooth completion of intestinal examination or bowel treatment with enteroscope.

Objective To investigate the influence of gender on the enmcement of neuromuscular blocking effects of cisatracurium or rocuronium by sevoflurane. Methods Two hundred and forty ASA Ⅰ or Ⅱ patients, aged 20-60 yr, weighing 45-85 kg, scheduled for elective surgery under general anesthesia were assigned into 2 groups ( n = 120 each): cisatracurium group and rocuronium group. Each group were divided into 4 subgroups according to gender and anesthetics ( n = 30 each): female propofol group, male propofol group, female sevoflurane group and male sevoflurane group. Anesthesia was induced with midazolam, propofol and fentanyl. After loss of consciousness, the laryngeal mask was inserted and the patients were mechanically ventilated. Propofol groups received target-controlled infusion (TCI) of propofol (target plasma concentration 2-6 μg/ml), and sevoflurane groups inhalation of sevoflurane. Cisatracurium 0.15 mg/kg or rocuronium 0.6 mg/kg was injected intravenously 5 min after propofol infusion or after the end-tidal concentrion of sevoflurane was maintained at 1.71% (1 MAC) for 5 min. Neuromuscular block was assessed with accelerograph F (TOF-watch SX). Train-of-four (TOF) stimulation of ulnar nerve was used. The onset time, duration of peak effect and times for recovery of T1 to 25% and TOF ratio (TOFR) to 25% were recorded.Results Compared with propofol groups, the time for recovery of TOFR to 25 % for rocuronium, and the duration of peak effect and times for recovery of T1 to 25 % and TOFR to 25% for cisatracurium were significantly prolonged in female sevoflurane group, the onset time of rocuronium was significantly shortened, while the duration of peak effect and times for recovery of T1 to 25% and TOFR to 25% for rocuronium and cisatracurium were significantly prolonged in male sevoflurane group ( P ＜ 0.05 or 0.01 ). The times for recovery of T1 to 25% and TOFR to 25% for rocuronium and onset time of cisatracurium were significantly shorter in female than in male during sevoflurane anesthesia (P ＜ 0. 05 or 0.01 ). Conclusion The enhancement of rocuronium-induced neuromuscular block by sevoflurane is stronger in male than in female,but there is no gender variation in the enhancement of cisatracurium-induced neuromuscular block by sevoflurane.

Objective To investigate the influence of fixed nurse specialists triage to improve the quality of patient triage.Methods Nurses were divided into the fixed nurse specialist triage group (group A) and the out-patient department rotation nursing group (group B),respectively,each group was responsible for triage of patients in clinic of medical department for five days.Then the number of two subdiagnosis error and the average daily working overtime for doctors were compared.Results A total of 3806 patients were in clinic triage in group A,165 patients had triage error.A total of 3812 patients were in clinic triage in group B,308 patients had triage error.The average daily working overtime of doctors in group A was(5.24 ± 0.37)hours,and(8.16 ± 0.58) hours in group B.The errors in triage and working overtime of doctors had significant differences between two groups.Conclusions Fixed specialist nurse triage can significantly improve the quality of patient triage in clinic.

Background and purpose:Selenium is one of the essential trace elements for human activities, and plays an incomparable role in maintaining human health. It was reported that selenium compound 1,4-bis[2-(benzylse-lanyl)ethoxy] (BSEA) anthracene has antiseptic and antiphlogistic effects. However, the mechanisms underlying anti-cancer effects of BSEA are rarely reported. BSEA-induced apoptosis in human laryngeal carcinoma Hep-2 cells and its mechanisms were studied.Methods:Methyl thiazolyl tetrazolium (MTT) assay was used to determine inhibition ratio of Hep-2 cells 24 hours after Hep-2 cells were treated with different concentrations of BSEA. Fluorescence microscope was used to observe the morphology change of apoptosis in Hep-2 cells. The apoptosis was detected by Annexin Ⅴ-FITC. Mi-tochondrial membrane potential was assayed by JC-1. Microplate reader detected the activity of caspase-3 and caspase-8. The mRNA and protein levels of Bax and XIAP were measured by real-time fluorescent quantitative polymerase chain reaction (RTFQ-PCR) and Western blot.Results:The results showed that BSEA caused a dose-dependent inhibition of the growth of human laryngeal carcinoma cell line Hep-2in vitro, andIC50 was 35.74μmol/L. The apoptotic bodies were distinctly observed at a concentration of 80μmol/L of BSEA by AO fluorescence staining. This study found that the eversion of phosphatidyl serine intensified, and mitochondrial membrane potential also began to decline. The activity of caspase-3 appeared the tendency of dependence on dosage, while the activity of caspase-8 did not change significantly. The mRNA and protein expression level of Bax increased, whereas the mRNA and protein expression level of XIAP de-creased.Conclusion:Therefore, BSEA could obviously inhibit human laryngeal carcinoma Hep-2 cells proliferation and induce apoptosis via the mitochondrial pathway.
