OBJECTIVETo explore the TCM therapy for puerperal albuminuria (PA) in patients with gestational hypertension syndrome (GHS).
METHODSSeventy-two GHS patients with PA in the severe preeclampsia stage were assigned to the treated group (38 cases) and the control group (34 cases). They were treated, starting from the postpartum second day, with Nifedipine 10 mg three times per day, but to the treated group, Shenkangbao (SKB, a TCM patent drug for stasis resolving and dinresis) was given additionally at the dose of 10 g twice a day, 3 weeks as one therapeutic course for all. Changes of urinary albumin quality and quantity, plasma total protein and albumin, as well as renal function and blood pressure before and after treatment were observed.
RESULTSSignificant difference after treatment between the two groups was shown in terms of percentage of cases with positive albuminuria (0.7 +/- 0.8 vs. 1.5 +/- 0.9), 24-h urinary albumin (520 +/- 480 mg vs. 1352 +/- 861 mg), plasma total protein (74.5 +/- 6.3 g/L vs. 67.8 +/- 6.2 g/L), and plasma albumin (39.4 +/- 4.5 g/L vs. 34.6 +/- 4.3 g/L, all P < 0.01); also in urinary albumin negative inversion rate (92.1% vs. 67.6%, P < 0.01). No significant difference of renal function between groups, and between pre- and post-treatment was found (P > 0.05), as for the blood pressure, it showed a significant difference between pre- and post-treatment in both groups (P < 0.01), but with no difference between groups (P > 0.05).
CONCLUSIONTCM therapy for stasis-resolving and diuresis with SKB can promote the eliminating of albuminuria in puerpera in the severe preeclampsia stage.

Objective To explore the effect of suramin on the epithelial-mesenchymal transition (EMT) and the excretion of transforming growth factor-β1 (TGF-β1) in peritoneal mesothelial cells (PMCs) induced by high concentrations of glucose solution (GS).Methods Cultured PMCs were divided into three groups:(1) normal control group; (2) GS-treated group:cells were treated with 1.5%,2.5%,4.25% GS for 12 h,24 h,48 h,respectively; (3) Suramin-treated group:PMCs cultured with 4.25% GS were exposed to different doses of suramin (25,50,100 μmol/L) for 48 h.Expression levels of α-smooth muscle actin (α-SMA) and E-cadherin were detected by Western blotting and the concentration of TGF-β1 in the culture supernatant was determined by ELISA.Results Compared with normal control group,GS-treated PMCs exhibited a time-dependent increase in the expression of α-SMA,and decrease in the expression of E-cadherin.GS also stimulated PMCs to secrete TGF-β1.In the presence of suramin,GS-induced α-SMA expression and TGF-β1 production were reduced,E-cadherin expression was increased.Conclusions Suramin can inhibit high glucose-induced EMT of PMCs by down-regulating the expression of TGF-β1.Suramin may be a novel therapeutic agent for the treatment of peritoneal fibrosis.

Objective To discuss the effects of extract of Ginkgo BilobaLeaves(EGb) on expression of cytokine of renal interstitial fibrosis induced by transforming growth factor-?1 (TGF-?1) and extracellular matrix. Methods Cultured human kidney cells(HKC) were divided into three groups: control group,TGF-?1(8 ng/mL) group,and TGF-?1(8 ng/mL) added EGb(25,50,100,150 mg/L)group.After 72 h,expression of ?-SMA was detected by cell immunochemistry ABC,and collagen type I by Real-time PCR and Western blotting. Results Treated with TGF-?1(8 ng/mL) for 72 h,expression of ?-SMA and collagen type Ⅰ were up-regulated markedly compared with control group.Treated with EGb(25,50,100,150 mg/L)and TGF-?1(8 ng/mL)concomitantly for 72 h,expression of ?-SMA and collagen typeⅠ were down-regulated in dosage dependent manner compared with TGF-?1 group. Conclusion EGb can inhibit expression of ?-SMA and collagen type I in HKC induced by TGF-?1,and the possible mechanism might be related to the inhibition of EGb on renal tubular epithelial-myofibroblast transdifferentiation.
