Danshen,an efficacious agent for cardiovascular diseases,has been found to play an essential role in kidney injury.In the present study,the effect of Danshen on cisplatin-induced renal dysfunction was investigated in a mouse model.Danshen was administered to mice at a dose of 3 g/kg 4 days before and 3 days after cisplatin treatment.A single intraperitoneal injection of 20 mg/kg cisplatin was used to induce nephrotoxicity.The mice were sacrificed 72 h after cisplatin intoxication.Biochemical parameters including serum creatinine and blood urea nitrogen were analyzed.Histopathological changes of kidney tissues were detected using HE staining.Antioxidant enzymes (GSH-Px and SOD) and peroxidative product (MDA) were detected.Protein expressions of Nrf2 and its target genes including HO-1 and NQO1 were measured by Western blotting.The results showed that pretreatment with Danshen significantly reduced serum creatinine and blood urea nitrogen in the cisplatin-treated mice.Histopathological examination showed that Danshen mitigated the renal damage induced by cisplatin.Moreover,Danshen restored the activities of antioxidant enzymes (GSH-Px and SOD) and normalized the MDA contents in renal tissues.Western blotting revealed that Danshen enhanced the expressions of Nrf2 and its target genes in cisplatin-exposed mice.It was suggested that Danshen protects against the cisplatin-induced renal impairment in the mice,which is potentially associated with the upregulation of Nrf2-mediated signaling pathway.

Eleven compounds were isolated from the culture of Streptomyces sp. CPCC 202950 by a combination of various chromatographic techniques including column chromatography over macroporous resin HP-20, MCI, and reversed-phase HPLC. Their structures were identified as 1H-pyrrole-2-carboxamide(1),5'-deoxy-5'-methylthioinosine(2), vanillamide(3), trans-3-methylthioacrylamide(4), 1,2,3,4-Tetraydro-1H-pyrido[3,4-b]indole-3-carboxylic acid(5), cyclo(L-pro-L-tyr) (6), N-[2-(4-hydroxyphenyl)]ethylacetamide(7), benzamide (8), cyclo ('L-leucyl-trans-4-hydroxy-L-proline)(9), cyclo-(Phe-Gly) (10), and tryptophan (11). Among them, compounds 1 and 2 were new natural products. In the preliminary assays, none of the compounds exhibited obvious inhibition of HIV-1 protease activity (IC50 > 10 micromol x L(-1)).

Objective To investigate the effect of Zishen Yutai Pills on follicle apoptosis and related protein expression in diminished ovarian reserve(DOR) rat model induced by tripterygium glycosides.Methods Forty rats were divided into the control group,model group,progynova group,and Zishen Yutai Pills high and low dose groups,8 cases in each group.Tripterygium Wilfordii Glycosides Tablets were given by gavage for establishing the rat DOR model.Then the HE staining was used to detect the pathological morphology of rat ovary.All levels of follicles were counted.Expression levels of Bcl-2 and Bax protein in follicle and ovarian stroma of each group were detected by using the immunohistochemical method.Results Compared to the control group,the number of great and small follicles in the model control group was decreased,number of atretic follicles was increased,Bcl-2 expression in all kinds of follicles was decreased,and Bax expression was increased,the differences were statistically significant(P＜0.05).Compared to the model group,the number of great and small follicles in the Zishen Yutai Pills high and low dose groups and progynova group was increased,number of atretic follicles was decreased,the Bcl-2 expression in great and small follicles was significantly increased and the Bax expression was significantly decreased,the differences were statistically significant(P＜0.05).Conclusion Zishen Yutai Pills can inhibit the premature and too fast follicles apoptosis by upregulating the expression of Bcl-2 protein and down-regulating the expression of Bax protein,thus plays the effect for treating DOR.

OBJECTIVETo study the association of alanine aminotransferase (ALT) with overweight or obesity in children.

METHODSA total of 2889 healthy children and 702 overweight or obese children aged from 7 to 18 years who had received a physical examination were enrolled. Height, body weight, waist circumference, and blood pressure were measured, and the biochemical indicators including blood glucose, blood lipids, ALT, and insulin were detected. The insulin resistance index were calculated.

RESULTSThe ALT level was significantly higher in boys than in girls. Along with the increase of BMI, the ALT level increased in the normal, overweight, and obese groups in both boys and girls. ALT was correlated with BMI, waist circumference, triglyceride, and insulin resistance index. Among the overweight or obese children, the boys with the increased ALT level had higher BMI, waist circumference, blood pressure, triglyceride, low density lipoprotein and insulin resistance index than the boys with normal ALT level (P<0.05); the girls with the increased ALT level had higher waist circumference, blood pressure and insulin resistance index and lower high density lipoprotein than the girls with normal ALT level (P<0.05).

CONCLUSIONSALT is correlated with overweight and obesity and metabolic disorders caused by overweight and obesity such as dyslipidemia and insulin resistance.

AIMTo investigate the impact of CYP2C9 * 3 on the pharmacokinetics of glibenclamide and lornoxicam.

METHODSCYP2C9 * 3 was measured in 83 non-related Chinese subjects by PCR-RFLP. The pharmacokinetics of lornoxicam and glibenclamide were investigated in 18 subjects (7 with CYP2C9 * 1/* 3 genotype and 11 with * 1/* 1 genotype). Glibenclamide and lornoxicam in plasma were determined by the sensitive liquid chromatography-tandem mass spectrometry, separately.

RESULTSAfter a single oral dose of 2.5 mg glibenclamide, C(max) was (70.0 +/- 11.5) microg x L(-1) in CYP2C9 * 1/ * 3 subjects and (51.9 +/- 12.3) microg x L(-1) in * 1/ *1 subjects. AUC(0-infinity) were (435 +/- 47) vs (287 +/- 95) microg x h x L(-1) (in * 1/ * 3 vs * 1/ *1 subjects), and CL/F were (96 +/- 9.3) vs (160 +/- 51) mL x min(-1), respectively. Statistic analysis results indicated that glibenclamide AUC(0-infinity) was significantly higher (1.5-fold) and subsequently CL/F was significantly lower (40%) in CYP2C9 * 1/ * 3 subjects than those in * 1/ * 1 subjects (P < 0.01). After a single oral dose of 8 mg lornoxicam, C(max) was (1.54 +/- 0.24) mg x L(-1) in CYP2C9 * 1/ * 3 subjects and (1.19 +/- 0.37) mg x L(-1) in * 1/ * 1 subjects. AUC(o-infinity were (14.9 +/- 2.2) vs (6.92 +/- 1.48) mg x h x L(-1) (in * 1/ *3 vs * 1/ * 1 subjects), and CL/F were (9.1 +/- 1.2) vs (20.1 +/- 4.6) mL x min(-1), respectively. Statistic analysis results indicated that lornoxicam AUC(0-infinity) was significantly higher (2. 2-fold) and subsequently CL/F was significantly lower (55% ) in CYP2C9 * 1/ * 3 subjects than those in * 1/ * 1 subjects (P < 0.001).

CONCLUSIONCYP2C9 * 3 greatly affects both the pharmacokinetic profiles of glibenclamide and lornoxicam. The elimination of these drugs significantly decreased in subjects with CYP2C9 * 1/ * 3 genotype, especially lornoxicam.

OBJECTIVETo evaluate the efficacy and safety of live combined Bifidobacterium, Lactobacillus and Enterococcus capsules in treatment of irritable bowel syndrome.

METHODSEighty-five patients [male 32, female 53; age (45.31+/-11.72) years] were given live combined Bifidobacterium, Lactobacillus and Enterococcus capsules 1260 mg/d t.i.d.x4 weeks. Syndrome scales were used to evaluate the efficacy in gastrointestinal syndrome. Fecal flora was also measured before and after the treatment. Six bacteria were cultured and the colony forming units were counted in stool. SPSS was used for data analysis.

RESULTSSeventy-four patients finished the follow-up. No side-effect was found. For treatment of irritable bowel syndrome, the effective rate of live combined Bifidobacterium, Lactobacillus and Enterococcus capsules was 56.8% in the second week, 74.3% in the fourth week and 73.0% in the sixth week. Single symptom was improved, especially in abdominal pain and stool character. The probiotica containing live combined Bifidobacterium, Lactobacillus and Enterococcus could increase bifidobacterium count (P<0.01) and lactobacillus count (P<0.05); decrease bacteroides count (P<0.05) and enterococci count (P<0.01); No obvious changes were observed in clostridium difficile colonitis and enterobacteriaceae (P>0.05).

CONCLUSIONThe result of the study indicated that the administration of live combined Bifidobacterium, Lactobacillus and Enterococcus improved the symptom of irritable bowel syndrome and that there was a gradual increase of this effect. Thereafter conditions remained stable for 2 weeks. That improvement may be associated with alterations in gastrointestinal flora.
