OBJECTIVETo study the rules of occurrence and development of TCM syndromes in patients of depression by analysing the population distribution and related factors of it.

METHODSA clinical epidemiologic survey was carried out with the materials collected by the four-diagnostic method from patients of depression to gain the syndrome types of 397 patients through dynamic cluster analysis, factor analysis and TCM syndrome differentiation. The constitution of syndrome types in different population and the relation between TCM syndrome types and the clinical types differentiated by Western medicine of depression was analyzed.

RESULTSSix syndrome types were found in 397 patients with depression. They were, ranging in occurrence order, the Gan-Qi stagnation with mental uneasiness type (108 cases, 27.2%); the Xin-Pi deficiency with dampness retention type (94 cases, 23.7%); the Xin-Gan Qi-stagnation with Phlegm retention type (76 cases, 19.1%); the Xin-Gan Qi stagnation with Jing-Luo disharmony type (57 cases, 14.3%); the Xin-Shen Qi stagnation with collateral obstruction type (34 cases, 8.6%); and the Xin-Gan Qi stagnation with Heat interfering mental type (28 cases, 7.1%). There were statistical significance (P < 0.01) in comparison of the syndrome types constitution among patients of different ages or different Western medicinal types (mild, with or without psychotic symptoms), but no significant difference was shown in that among patients of different sexes, with or without familial history of mental diseases, with monophasic or biphasic, initial or recurrent episode (P > 0.05).

CONCLUSIONThe result obtained in this study is basically in accord with the cognitive rule of TCM theory, it provides a reliable base of syndrome differentiation for treatment.

Objective To investigate the relationship between pure -tone audiometry (PTA ) ,speech dis‐crimination abilities in quiet or in noise and the international outcome inventory for hearing aids (IOI-HA) in pres‐bycusis patients .Methods Twenty presbycusis subjects were tested in this study .Pure-tone audiometry (PTA) and speech discrimination threshold were obtained before being fitted with hearing aids .They weared hearig aids more than six months ,and pure-tone audiometry ,speech discrimination scores in quite(the level = 65 dB SPL) and in noise(signal to noise ratio = 10 dB) were carried out in sound field .A stepwise forward multiple-regression analysis was performed to investigate the impact of PTA and speech discrimination scores to IOI-HA .Results The PTAs before or after hearing aid fittings showed a negative association with IOI-HA ,while speech discrimination scores in quiet or in noise before or after hearing aid fittings showed a positive association with IOI-HA .Speech discrimination threshold in noise was identified as a single predictor of IOI-HA(P<0 .001) .Conclusion The relation between speech discrimination scores in noise and IOI-HA suggests that a poor score might limit the hearing aids outcome .The speech discrimination scores in noise help the clinicians predict the outcomes of hearing aid in real‐ities .

Evaluation of the permeability mainly focuses on intestinal absorption in biopharmaceutics classification system (BCS). It is more complicated that the absorption and metabolism under multicomponent environment in biopharmaceutics classification system of Chinese materia medica (CMMBCS) compared with single component environment, which needs suitable mathematical models to be described. Therefore, with full consideration of existing single component mathematical algorithm combining with the characteristics of intestinal absorption and metabolism, we explored and designed a new mathematical algorithm of intestinal absorption and metabolism of multicomponent drug. Then we put forward a new coefficient, P (influence), the relative change rate of the single component's intestinal absorption and metabolism under multicomponent environment compared with single component environment, which described the influences of intestinal absorption and metabolism of the component under multicomponent environment. Moreover, P (influence) highlights the distinctive characteristics of multicomponent drug's intestinal absorption and metabolism, and lays the foundation for the construction of CMMBCS.

OBJECTIVE: To investigate the changes of electrode impedance, THR/MCL values, and dynamic range (DR) in Combi 40+ cochlear implant after implantation. METHOD: A respective study was carried out collecting 20 consecutively implanted children's electrode impedances, THR/MCL values, and DR at seven time point during the first three years after implantation. Their variation and correlations were analyzed. RESULT: Overall, electrode impedances were lowest during the operation, and significantly rise to the highest at the first stimulation, then followed by a gradual decrease. After three months, electrode impedance of apical and medial cochlear segment were basically stable, while that of the basal segment was gradually increased. Dynamic range (DR) of apical and medial group electrode increased early after the operation and showed a stabilization from the second year, whereas that of basal group have a downward trend since the first year. However, the electric charge of each group increased significantly after three months, and then become stable after first year. Otherwise, a stronger negative rectilinear correlation was found between impedance changes with DR than with THR/MCL level. CONCLUSION The electrode impedances vary clue to different electrode position. Measuring the electrode impedance can effectively evaluate the working status of Combi C40+ cochlear implant. The dynamic range of the electrode was negatively correlated with the impedances, which made it possible to predict the width of the dynamic range by measuring the impedance 3 or 6 months after operation.

The dynamic changes of germination percentage, germination potential, thousand-seed weight, antioxidase activity in Desmodium styracifolium seeds with different storage time were tested, and electrical conductivity, contents of soluble sugar, soluble protein, starch in seed leach liquor were also determined in order to reveal the mechanism of seed deterioration. The results as the following. (1) The germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds declined, while the seed coat color darkened with the extension of storage time. (2) The activities of superoxide dismutase (SOD) and peroxidase (POD) decreased with the prolongation of storage period. The SOD activity declined fastest in 1,095-1,185 d of storage, while the POD activity declined significantly in 365-395 d of storage. (3) The electrical conductivity and the contents of soluble sugar, starch in seed leach liquor increased, while the content of soluble protein declined with the extension of storage time. (4) Correlation analysis indicated that the germination percentage, germination potential and thousand-seed weight of D. styracifolium seeds have a significantly positive correlation with SOD and POD activity, while have a significantly negative correlation with the electrical conductivity, contents of soluble sugar and starch. It can be concluded that during the storage of D. styracifolium seeds, physiological and biochemical changes including decrease in antioxidase activity, rise in electrical conductivity, degradation effluent of soluble sugar and starch, degradation of soluble protein were the main factors leading to the seed deterioration.
