Fibroblast growth factor-21 (FGF-21) is an important metabolism regulator, however, whether FGF-21 has effects on cardiovascular remains unclear. In this study, H2O2-induced injury in H9c2 cells was used as a cell model, the anti-apoptosis potential and mechanism of FGF-21 against oxidative injury were evaluated by MTT assay, flow cytometry assay and real-time PCR. The results showed that FGF-21 could increase the cell survival of H2O2-induced injury in H9c2 cells and prevent H9c2 cells from oxidative stress-induced apoptosis. Furthermore, FGF-21 can elevate SOD activity and regulate Bcl-2/Bax expression in H9c2 cells. The results suggest that FGF-21 have protective effect against the H2O2-induced apoptosis in H9c2 cells.

This study aims to analyze and compare the effect of cell wall-broken decoction pieces, conventional decoction pieces and conventional powder of Rhodiolae Crenulatae Radix et Rhizoma on the intestinal flora of normal mice. The conventional bacterial culture and PCR-DGGE (polymerase chain reaction-denaturing gradient gel electrophoresis) were adopted for the mice after the oral administration for 14 days. According to the bacterial culture results, the 1/8 dose cell wall-broken decoction pieces group showed fewer Enterococcus and Escherichia coli bacillus but more Lactobacillus and Bifidobacterium than the conventional decoction pieces group and the traditional powder group (P <0.05). Meanwhile, on the basis of the PCR-DGGE results, the 1/8 dose cell wall-broken decoction pieces group revealed the highest Shannon-Wiener index (H) and species richness (S) among the seven groups, with extremely significant differences compared with the normal group (P <0.01), significant differences compared with the conventional decoction pieces group and the conventional powder group (P <0.05) and a high intra-group similarity. In conclusion, the long-term intake of 1/8 dose Rhodiolae Crenulatae Radix et Rhizoma cell wall-broken decoction pieces showed a certain effect in regulating intestinal tract by promoting the growth of Lactobacillus and Bifidobacterium. Furthermore, the intestinal flora community will become more stable.

OBJECTIVETo observe the clinical efficacy of Qi-supplementing and blood-activating (QSBA) in treating diabetic peripheral nephropathy (DPN).
METHODSSixty-eight type 2 diabetes mellitus patients with Qi deficiency-blood stasis Syndrome were randomly divided into two groups, the neurotrophic agents were used in both groups, while QSBA herbs were used in the treated group additionally. The treatment course was 2 months. Blood glucose (BG), triglyceride (TG), total cholesterol (TC) and nerve conduction velocity (NCV) were detected before and after treatment.
RESULTSAfter treatment, the BG, blood lipid, NCV were improved significantly (P < 0.05) in both groups, but the improvement was more significant in the QSBA treated group than in the control group (P < 0.05).
CONCLUSIONQSBA, in treating DPN, can not only improve its symptoms, but also ameliorate the NCV.

By means of preparative HPTLC and column chromatography over silica gel and Sephadex LH-20, nine diterpenoids were isolated and purified from the whole plants of Scutellaria strigillosa. Based on the physico-chemical properties and spectral data, their structures were elucidated as: 6-O-acetyl-7-O-nicotinoylscutebarbatine G(1), 6-O-nicotinoyl-7-O-acetylscutebarbatine G(2), 6,7-di-O-nicotinoylscutebarbatine G(3), scutebarbatine K(4), scutebarbatine B(5), 6-O-acetylscutehenanine A(6), 6-O-nicotinoylbarba- tin A(7), 6,7-di-O-acetoxylbarbatin A(8), scutebarbatine F(9). Compound 1 is a new diterpenoid, and compounds 2-9 were isolated from Scutellaria strigillosa for the first time.

Objective To determine chromosomal localization of the primary gout susceptibility gene in a pedigree.Methods The clinical data and the peripheral blood samples were collected in the pedigree members and the genomic DNA was extracted from peripheral blood.A genome-wide screening was performed using 400 micro-satellite DNA markers in this family,and linkage analysis was used to determine the chromosomal location of the primary gout susceptibility gene.Results Linkage analysis showed that the maximum LOD score reached 1.50 at marker D4S1572 (at recombination fraction?=0.00).Conclusion Since D4S1572 is localized at 4q25,the primary gout susceptibility gene of this pedigree is localized at 4q25.

Objective To study the impact of preprocedure intravenous urography(IVU)on the outcome of shock wave Iithotripsy(SWL)for the middle and lower ureteral stones.Methods 112 patients with solitary radiopaque the middle and lower ureterat stones on plain radiographs and no severe hydronephrosis on ultrasonographic examination were divided randomly to two treatment groups.IVU group(n=56)had IVU before the start of SwL,whereas patients in the control group(n=56)underwent SWL without IVU.Postoperative success,stone-free rates and complications were evaluated in both groups.Results Eleven patients in the IVU group were excluded from the study.The SUCCESS rate[91.1%(41/45)in IVP group VS 94.6%(53/56)in control group],stone-free rate[88.9%(40/45)vs 89.3%(50/56)],and complication rate[22.2%(10/45)vs 21.4%(12/56)]were similar in two groups(P>0.05).ConclusionIt is not necessary to obtain an IVU for patients who have solitary radiopaque the middle and lower calculi on plain radiographs with no severe hydronephrosis on ultrasonographic examination before scheduling them for SWL,thus minimizing the cost,avoiding exposure to contrast medium,and reducing radiation exposure.
