A total of 89 elderly patients with heart failure and preserved ejection fraction were randomly divided into 2 groups:patients in control group received conventional medication,those in exercise group receive conventional medication plus aerobic exercise training,which was lasted for 6 weeks.The changes in VO2max,maximum heart rate (HRmax),VO2max/HRmax,exercise time,6-minute walk and quality of life (QOL) were evaluated after 16 weeks.The VO2max,HRmax,VO2max/HRmax,exercise time,6-minute walk and QOL had increased significantly in exercise group,compared with the control group.The results indicate that aerobic exercise can improve cardiopulmonary function of elderly patients with heart failure and preserved ejection fraction.

Objective To construct human SREBP-1c-promoter reporter gene vector and to detect its function.Methods Human blood genome DNA was extracted and pGL3-Basic-SREBP-1c-promoter reporter gene vector was constructed.Furthermore,the function of SREBP-1c-promoter was confirmed by dual-luciferase reporter assay.ResultspGL3-Basic-SREBP-1c-promoter reporter gene vector was successfully constructed and the promoter activity was obviously repressed by co-transfection FoxO1.Overexpression FoxO1 inhibited the SREBP-1c protein expression.Conclusion FoxO1 repressed the SREBP-1c protein expression through inhibition the SREBP-1c transcription.

OBJECTIVETo determine the apoptotic and proliferative activities in various ovarian epithelial tumors.
METHODSFormalin-fixed, paraffin-embedded tissues of 86 ovarian epithelial tumors, including 52 adenocarcinomas, 23 borderline tumors and 11 cystadenoma, were retrieved. Apoptotic (AI) and proliferative (PI) index were estimated using the monoclonal antibodies: M30, Ki-67 and Ki-S1 in these tumors. Quantitative assessment of AI and PI was estimated by calculating the percentage of positive cells among no less than 1000 tumor cells.
RESULTSStatistically significant difference in AI was found between benign and borderline tumors or carcinomas (P = 0.028, 0.001, respectively). Significant differences in PI, as assessed by both Ki-67 and topo IIalpha, were demonstrated between carcinomas and benign or borderline tumors (both P < 0.001). Benign tumors had both low PI and AI; borderline tumors had lower PI but higher AI, while adenocarcinomas had both high proliferative and high apoptotic rates. Among borderline tumors, serious tumors had significantly lower AI and higher PI than mucinous ones.
CONCLUSIONThe results suggest that apoptotic and proliferative activities play important roles in the pathogenesis and development of ovarian borderline and malignant tumors. The high apoptotic rate in borderline tumor may explain its relatively indolent behavior while the high proliferative rate in carcinomas tends to explain its aggressive behavior.

ObjectiveTaking Shengxuebao as the model traditional Chinese medicine(TCM), this study aims to explore the methodologies and transfer patterns in the composition changes of TCM compound preparations from liquid to solid dosage forms. MethodBased on the previously established ultra-high performance liquid chromatography(UPLC) qualitative and quantitative methods for Shengxuebao, the fingerprint profiles of three preparations of Shengxuebao(homemade decoction, commercially available granules and mixtures) were established, and nineteen components were quantitatively analyzed. The similarities of fingerprint profiles among these three preparations were assessed using the Similarity Evaluation System for Chromatographic Fingerprint of TCM(2012 edition) and the total quantum statistical moment similarity method, respectively. The molecular connectivity index (MCI) and the average molar MCI of the chemical components in the three preparations were calculated. Seventy-two MCI values across 0-8 orders, including 8 subclasses, were calculated. The average molar MCI of 0-3 orders was used to study the "imprint template" structural characteristics and transfer patterns of the medicinal component groups. ResultThe similarities of the fingerprint profile of the decoction with those of the control, granules, and mixtures were 0.971, 0.888 and 0.799, respectively, indicating that the chemical composition of the granules and mixtures differed from that of the decoction, and that the 19 components were able to basically respond to the overall situation of the component group of Shengxuebao decoction. The total mass fractions of the detectable major components in Shengxuebao decoction, granules and mixtures was measured to be 5.498 6, 2.282 0, 1.416 6 mg·g-1, respectively. The average molar MCI of 0-3 orders showed a gradual decrease across the three preparations, with the trend of decoction>granules>mixtures, indicating subtle changes in the overall structural characteristics of the chemical components in the samples of the three preparations. ConclusionAmong the three formulations of Shengxuebao, the traditional decoction contained the highest variety and quantity of components and carried the most substantial amount of component information, with a decreasing order observed in the granules and mixtures. This study further validates that traditional decoction is a reliable and fundamental dosage form, providing a reference for the modernization of TCM dosage forms and the quality consistency evaluation of compound preparations.
