Objective: This study aimed to improve the reconstituability of kudzu powder. Methods: The kudzu powder-fatty acid complexes were prepared by different drying methods after co-gelatinization of kudzu powder with lauric acid, and investigated the effects of drying methods on the instant properties of the complexes from the changes of crystal structure, microstructure, bulk density, water absorption index and swelling power. Results: The drying method influenced the water absorption capacity of the complexes, there by affected the reconstituability of the complexes. Compared with oven drying and far-infrared drying, the complexes prepared by spray drying and freeze-drying had lower bulk density, more uneven particle surface and more amorphous structures, which made them more absorbent and better reconstituability. Conclusion: The agglomeration rate of the spray-dried and freeze-dried complexes was 4.6%~6.0% after directly mixing with hot water at (95±2) ℃, which was 36.3% lower than that of the native kudzu powder, indicating that the kudzu powder-fatty acid complexes have the potential to be developed into hot water ready-to-eat kudzu powder.

Soybeans from Jiangxi, Heilongjiang, Jilin and Anhui were digested by nitric acid. The contents of mineral elements K, P, Mg, Ca, Fe, Al, Zn, Mn and Na in four samples were analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). The differences between samples were determined by Duncan's multiple-range test, and evaluations were based on a significance level of P < 0.05. The results show that soybeans are rich in mineral elements that human body needs. The contents of K, P, Mg, Ca and Fe are higher than the others, and the order from high to low does not change with the producing area. The order of Mn, Zn, Al, Na varied with the producing area. Producting area does not affect the contents of elements K, P and Mg significantly (P > 0.05). It can be concluded that the demands for major mineral elements K, P and Mg are stable in the growth of soybeans with the same variety. However, producing area has a great influence on the contents of elements Al, Ca, Fe, Na, Mn and Zn in soybean (P < 0.05). The content of Fe in Anhui soybean (70.93 mg x kg(-1)) and the content of Mn in Jiangxi soybean (32.69 mg x kg(-1)) are significantly higher than the other three samples. The results suggested that the contents of Al, Ca,Fe, Na, Mn and Zn were easily affected by growth conditions, such as water, soil and so on.

The present research investigated the effect of dynamic high pressure microfluidization (DHPM) in low pressure ranges (60-100 MPa) on the molecular structure of papain with the help of fluorescence spectra as the detection method. The result showed that after the treatment of DHPM at 60-100 MPa, the fluorescence intensity of papain, tryptophan (Trp) and tyrosine (Tyr) residues all decreased to different extents. Meanwhile, with the increase in the treatment pressure, their fluorescence intensity would gradually increase and the fluorescence emission peak would gradually red shift from 334 and 277. 5 nm before treatment to 335 and 278 nm after 100 MPa treatment for papain and Trp residue respectively; after the treatment, with the samples being placed at 0-4 degrees C for 24 h, the fluorescence spectra of papain, Tyr and Trp residues in various experiment groups basically maintained the same changing tendency compared to that of newly treated samples. Hence, it showed that after the treatment of DHPM in low pressure ranges, the Trp residue of papain was gradually brought to light and formed new and comparatively stable molecular conformation.

Objective: To observe the effect of moxibustion combined with intermittent urethral catheterization on vesical function in the patient of neurogenic vesical dysfunction., Methods: Seventy-six cases were randomly divided into an observation group and a control group, 38 cases in each group. The control group was treated with routine intermittent urethral catheterization and the observation group with the intermittent urethral catheterization and moxibustion on Guanyuan (CV 4), Mingmen (GV 4), Zusanli (ST 36), etc. Changes of residual urine volume, white cell count and the balance state of the urinary bladder were selected as the indexes of therapeutic effect and the therapeutic effects were compared between the two groups., Results: The total effective rate was 97.4% in the observation group and 79.0% in the control group with a significant difference between the two groups (P < 0.05); after treatment, there were significant differences between the two groups in the residual urine volume, the bladder volume and the case numbers reaching to the functional balance state of bladder (all P < 0.05), and there was no significant difference between the two groups in white cell count change (P > 0.05)., Conclusion: Moxibustion combined with intermittent urethral catheterization can significantly improve vesical function in the patient of neurogenic vesical dysfunction, reducing residual urine volume, increasing volume of bladder, promoting the balance state of vesical function, but it is basically same as intermittent urethral catheterization in prevention of urinary infection and therapeutic effect.
