Table IV.

Comparison of 24 h urinary protein, BUN and SCr between the treatment group and the control group before treatment, at 2 weeks, 3 months and 6 months after treatment.

Group	24 h urinary protein (g)	BUN (mmol/l)	SCr (µmmol/l)
Control group (n=25)	1.01±0.23	4.32±0.88	63.58±14.4
Treatment group (n=28)
Before treatment	6.32±2.57	7.09±4.14	115.76±22.56
After treatment
2 weeks	5.08±1.98	6.01±3.82	90.31±18.25
3 months	3.02±1.14	4.93±3.61	79.54±9.57
6 months	1.31±0.98	4.34±1.27	64.37±10.63

i) Compared with the same group before treatment, P<0.01; ii) compared with the control group before treatment, P<0.01; iii) compared with the control group 6 months after treatment, P>0.05. BUN, urea nitrogen; SCr, serum creatinine.
