2.Efffects of hetrazane on contraction of isolated tracheal of guinea pigs
Chinese Pharmacological Bulletin 2001;17(2):200-202
AIM To study the efffects and mechanisms of hetrazane(diethylcarbmazine citrate,DEC)on contraction of isolated tracheal strips of guinea pigs. METHODS Using isolated tracheal strips technique. Each tracheal strip was placed in an organ bath filled with a Krebs solution of 37℃ and various drugs was added respectively. It was determined that KCl or 5-HT induced the contractile effects and its dose-response curve on tracheal strips and DEC or verapamil changed the effects of KCl or 5-HT. RESULTS The contractions induced by KCl or 5-HT in isolated tracheal strips of guinea pig were markedly inhibited by DEC, the IC50 value of DEC for contraction induced by KCl and 5-HT was 5.03 mmol*L-1 and 9.54 mmol*L-1 respectively. DEC caused rightward displacement of the dose-response curse for KCl and 5-HT, and significantly depressed the maxmal response, showing anon-competitive antigonism, the pD′2 values were 1.554 and 1.851 respectively, and DEC markedly inhibited the contractions induced by Ca2+ released from an intracellular store and extracellular Ca2+. CONCLUSION DEC can significantly inhibit contraction of tracheal strips induced by KCl and 5-HT, and its mechanism is responsible calcium-antagonistic effect of DEC.

International Journal of Traditional Chinese Medicine 2016;38(8):697-700
Objective To estimate the effect of Yiqi-Wenyang-Gujing decoction combined with the conventional western therapy on the elderly with chronic glomerulonephritis. Methods The 65 patients who conforming to the diagnostic criteria were randomly divided into the treatment group (33 patients) and control group (32 patients) according to the random number table. The control group was treated with the conventional western therapy, and the treatment group was treated with Yiqi-Wenyang-Gujing decoction based on the former treatment. After the treatment of 8 weeks, the curative effect of edema and the 24 hours urine protein and the changes of renal function were observed. Results Compare with the control group, the 24 hours urinary protein (0.8 ± 0.1 g vs. 1.3 ± 0.7 g, t=4.625), the SCr (132.0 ± 8.5μmol/L vs. 163.9 ± 6.2μmol/L, t=17.242) and the BUN (7.1 ± 2.2 mg/L vs. 9.2 ± 2.5 mg/L, t=3.598) of treatment group significantly decreased (P<0.01);The glomerular filtration rate of treatment group [(73.9 ± 4.2 ml/(min·1.73 m2) vs. 65.4 ± 2.4 ml/(min·1.73 m2), t=9.976] significantly increased (P<0.01). And the degree of edema was relieved more in the treatment group than that of the control group (P=0.049). The total effective rate of the treatment group was significantly better than that (78.8% vs. 46.9%, P=0.016) of the control group. Conclusion The combined Yiqi-Wenyang-Gujing decoction and western medicine treatment on the elderly with chronic glomerulonephritis could improve the kidney function and relieve edema.

6.Liver cancer CT image enhancement using wavelet transform
Chinese Medical Equipment Journal 1993;0(06):-
This paper introduces the wavelet transform with multiresolution for liver cancer CT image enhancement. As the wavelet transform with compact support, orthogonality and approximately symmetry, SymletsA (sym4) wavelet family is applied to the two-layer multiscale decompose of the CT image. The decomposed wavelet coefficients are processed with the threshold values of 550, 350 and 250, with the low -frequency region intensified and the high-frequency one weakened. Then the image is reconstructed and thus the image is enhanced. Wavelet transform proves efficient in CT image enhancement.
