Objective The Hilbert- Huang transformation (HHT) method was introduced to process the bio-impedance gastric motility signals from subjects.Methods Nonlinear and non-stationary original gastric motility series were decomposed into a number of intrinsic mode function (1MF) components by the empirical mode decomposition method (EMD).Hilbert transformation was carried out then and instantaneous frequency was extracted effectively.Gastric motility signal among 0.03-0.06 Hz was reconstructed from the IMF.Results The results suggested that HHT was a new and applicable time series analysis method based on mode decomposition and could extract impedance signal and remove the disturbances such as blood flow and breathing.Conclusion The new adaptive mode decomposition-based signal processing method provides a new method to investigate clinical gastric motility information.

Objective To know the influence of psychological intervention on delivery results of par-turient women, and then reference to certain effective psychological nursing cares for clinical field. Methods Divided 226 partreient women of spontaneous labor into the experimental group and the control group randomly, there were 113 eases in each group. Traditional routine nursing cares was used in the control group, psychological intervention was used in the experimental group in addition. Compared the condi-tion of birth process and the incidence rate of labor-related complications between the two groups. Re-sults There were significant differences between the two groups about all the indexes which had indicated the delivery. Conclusions Correct psychoanalysis and proper nursing intervention and effective release the pains for parturient women, and then decrease the incidence rate of medical negligence.

Objective To determine the content of astragaloside Ⅳin Qi Zao Granules.Methods Equipped with the evaporative light scattering detector (ELSD), a RP-HPLC method was established. The chromatographic column was C18 and the column temperature was at 30 ℃.The drift tube temperature was at 40 ℃and the evaporative gas was nitrogen with pressure of 3.5 bar.The mobile phase was acetonitrile-water(30∶70) and the flow rate was 1mL/min. Results This method showed a good linear relationship in the range of 2.51~50.2 ?g astragaloside Ⅳ. The average recovery was 98.13 %with RSD being 1.28 %. Conclusion The method is sensitive and accurate and can be used for the quality control of Qi Zao Granules.
