Objective To investigate the clinical value of laryngeal mask airway (LMA) in patients with a-cute severe asthma(ASA). Methods 32 patients with ASA treated with LIMA or mouth-nose mask during 2002 -2009 in our hospital were retrospectively analyzed. Those treated with laryngeal mask airway was taken as observation group and those with Mouth-nose mask as control group. Results The period to oxygen saturation in arterial blood, the time to remove ventilator, and the time to disease improvement in the observation group (389.63±32.82)s, (19.31±2.26) hours,(16.22±3.85) hours were different from that in control group (467.36±41.15) s, (25.18±3.73) hours,(23.66±2.38) hours (P<0.01). After non-invasive positive pressure ventilation, PaCO_2 decreased, PaO_2 and pH increased at 3 and 12 hours in the observation group (P<0.05 or 0.01) from that before treatment. PaCO_2 and pH at 3 hours in the control group were no significant difference before and after treatment (P > 0.05),with an exception of PaO_2 (P < 0.05). PaCO_2, PaO_2 and pH were significantly different (P < 0.05) at 12 hours after treatment from those before treatment. Conclusions LMA should be considered in the selection of non-invasive positive-pressure ventilation (NIPPV) in patients with ASA, for a better improvement of ventilation ef-fectivenoss and accelerating the mitigation of clinical manifestations.

Objective To research etomidate or propofol in the whole intubation during the induction of elderly coronary heart disease autonomic nervous system function. Methods Ninety patients undergoing abdominal surgery patients with coronary heart disease were randomly divided into etomidate group (E group, 45 cases) and propofol group (P group, 45 cases). In pre-anesthesia, after the induction of anesthesia and after intubatiou with power spectral analysis of heart rate variability (HRPSA) observed in patients with heart rate variability (HRV) changes. Results After the induction of anesthesia, the low frequency(LF)[(316±301) ms2/Hz] end total power(TP)[(756±535) ms2/Hz] decreased significantly in E group(P<0.05) and LF, high frequency (HF), LF/HF ratio(LF/HF)and TP decreased significantly in P group [ (187±168) ms2/Hz, (89±48)ms2/Hz, 2.3±1.6 and (616±462) ms2/Hz] (P<0.05). The duction degree of LF, HF, TP and LF/HF in E group was more significant than that in P group (P<0.05). After intubation, LF, HF, LF/HF and TP increased significantly in both groups and no significant difference of HRV was observed between the two groups (P>0.05). Conclusions Propofol decreases the activity of autonomic nervous system, wherea etomidate produces minimal changes under anesthesia induction in elderly coronary heart disease patients.There is no remarkable difference in cardiovasological changes induced by etomidate and propofol during tracheal intubation.

After testing the resistance of Streptomycin to the strain NS-41-80 which is the Meilingmycin producer- Streptomyces nanchangensis , a lot of streptomycin-resistant ( str ) mutants were screened after the spores regenerated on the lethal media when they were treated with 4 different dosage of super-mutagent EMS. We have abtained the high-yield strain 80-5. 11-221 from these str mutants which only produces Meilingmycin and no Nanchangmycin in the rotation-flask experiments. The productivity of 80-5. 11-221 is 1521?g/mL 77. 9% higher than CK's 855?g/mL. After the shake flask fermentation experiment of 80-5. 11-221 for six generations, the productivity of F 2 and F 3 is stable and the productivity of F 4?F 5?F 6 decreases hastily with the increment of generations. It was showed that the chemical-resistance mutation of the strains had closely relation with yield mutation and the EMS dosage of the yield mutation was higher than the resistance-chemical mutation's through the statistical analysis between the dosage of mutation and the chemical-resistance mutational frequency?the variate capacity of the mutants' yield. A model of the resistance-chemical mutational labelling rational selection of the strain producing Meilingmycin was established.
