OBJECTIVE:To study the improvement effects of polydatin on renal fibrosis in rats and its mechanism. METH-ODS:50 rats was were randomly divided into sham operation group,model group,positive group(benazepril,5 mg/kg)and poly-datin high-dose and low-dose groups(100,50 mg/kg),with 10 rats in each group. Except for sham operation group,renal fibrosis model was induced by unilateral ureter obstruction. After modeling,administration groups were given relevant medicine intragastri-cally,and sham operation group and model group were given 0.5%sodium carboxymethyl cellulose solution once a day for consec-utive 4 weeks. The pathological change of renal tissue was scored. 24 h urinary protein and serum levels of urea nitrogen and creati-nine were determined,and the content of hydroxyproline,mRAN expression of TGF-β1 and FN were detected in renal tissue. RE-SULTS:Compared with sham operation group,pathological score,24 h urinary protein,serum levels of urea nitrogen and creati-nine,the content of hydroxyproline in renal tissue,mRNA expression of TGF-β1 and FN were all increased significantly (P<0.01). Compared with model group,24 h urinary protein,serum levels of urea nitrogen and creatinine and mRNA expression of FN in renal tissue decreased significantly in administation groups;the pathology scores,the content of hydroxyproline in renal tis-sue and mRNA expression of TGF-β1 of positive group and polydatin high-dose group were all decreased significantly(P<0.05 or P<0.01). CONCLUSIONS:Polydatin can prevent kidney fibrosis induced by unilateral ureteral obstruction,the mechanism of which may be associated with the mRNA expression down-regulation of TGF-β1 and FN in renal tissue.

OBJECTIVE:To investigate the effects of neoadjunctive chemotherapy(NAC)of docetaxel and epirubicin com-bined with cyclophosphamide on clinical efficacy and tumor markers of breast cancer patients with different molecular types. METH-ODS:A total of 88 female patients with locally advanced breast cancer collected from our hospital during Jan. 2014-Jan. 2016 were divided into Luminal A type(23 cases),Luminal B type(21 cases),basal-like type(11 cases),HER2-over expressing type(18 cases)and normal breast-like type(15 cases)according to molecular type. All patients were given Docetaxel injection+Epirubicin hydrochloride injection+Cyclophosphamide for injection for consecutive 6 cycles(21 d as a cycle). Total response rates and patho-logical complete remission(pCR)rates were compared among breast cancer patients with different molecular types. The expression of serum tumor markers [CEA,CA125,CA153] were compared before and after treatment,and the occurrence of ADR was record-ed. RESULTS:Total response rate of 88 patients was 63.64%,among which that of basal-like breast cancer patients was 72.73%, significantly higher than other molecular types,with statistical significance(P<0.05). There was no statistical significance in total response rates of pairwise molecular type comparison(P>0.05). The pCR rate of 88 patients was 27.27%,and that of basal-like breast cancer patients was the highest(45.45%). There was statistical significance in pCR rates of pairwise molecular type compari-son(P<0.05),except there was no significant difference in pCR rate between HER2-over expressing type and normal breast-like type(P>0.05). Before treatment,there was no statistical significance in the expression of CEA,CA125 and CA153 in breast can-cer patients with different molecular types(P>0.05). After treatment,the expression of CEA,CA125 and CA153 in different mo-lecular types were decreased significantly,with statistical significance(P<0.05). There was no statistical significance in the expres-sion of above markers among different molecular types(P>0.05). There was no statistical significance in the incidence of ADR among different molecular types(P>0.05). CONCLUSIONS:NAC plan of docetaxel and epirubicin combined with cyclophospha-mide can reduce the expression of tumor markers and shows certain therapeutic efficacy for breast cancer patients with different mo-lecular types. Total response rate and pCR rate of basal-like type are better than those of other molecular types,so NAC plan is the preferred treatment for basal-like type breast cancer.

OBJECTIVE:To investigate the effects of polydatin on protein expression of MMP-9 and TIMP-1 in renal tissue of renal fibrosis model rats,and to investigate the mechanism of delaying renal fibrosis in rats. METHODS:A total of 40 rats were randomly divided into sham operation group(normal saline),model group(normal saline),polydatin group(100 mg/kg)and benazepril group(positive control,5 mg/kg). Except for sham operation group,renal fibrosis rat model was induced by unilateral ureteral obstruction in other groups. 1 h after surgery,each group was given relevant medicine intragastrically,once a day.After 4 weeks of consecutive treatment,the contents of β 2-microglobulin(β 2-MG)and N-acetyl-β-D-glucosaminidase(NAG)in urine, serum contents of BUN and Cr were detected in each group. HE staining was used to observe and score pathological changes of renal tissue in rats. Protein expressions of MMP-9 and TIMP-1 in renal tissue of rats were determined by immunohistochemistry. RESULTS:Compared with sham operation group,the contents of β2-MG and NAG in urine,serum contents of BUN and Cr were increased significantly in model group(P<0.05),and pathological score and protein expressions of MMP-9 and TIMP-1 were also increased significantly(P<0.01). Compared with model group,protein expression of MMP-9 in renal tissue were increased continuously in polydatin group and benazepril group(P<0.01);other indexes were decreased significantly(P<0.05 or P<0.01),and there was no statistical significance in each index between polydatin group and benazepril group(P>0.05). CONCLUSIONS:Polydatin can delay renal fibrosis,the mechanism of which may be associated with up-regulating protein expression of MMP-9,down-regulating protein expression of TIMP-1 and increasing the ratio of MMP-9/TIMP-1.
