BACKGROUND: Aerobic exercise is a popular and effective way of fitness. All kinds of changes occur in the human system, especially the changes in the cardiovascular system. Enhancing the cardiovascular system functions is the most important role in the aerobic exercise. OBJECTIVE: To sum up effects of aerobic exercise on blood indicators, cardio-vascular function. RETRIEVAL STRATEGY: A computer-based search was conducted in Pubmed for literatures related to aerobic exercise and cardiovascular system published between January 1998 and December 2006 with the key words of "aerobic exercise, cardiovascular" in English. Simultaneously, China Journal Full-text Database was looked for relevant articles published from January 2001 to December 2006 with the same key words in Chinese. The data were selected firstly. Inclusive criteria: ①the influence of aerobic exercise on cardiovascular function, ②influence of aerobic exercise on blood indexes. The exclusive criterion for deletion was the repetition of the same research. There were 81 literatures in accordance with the above-mentioned criteria. LITERATURE EVALUATION: 51 papers of repetitive research were excluded, 30 of them were accorded with the inclusive criteria and were included. DATA SYNTHESIS: Aerobic exercise plays the most important role in fitness. Enhancing the cardiovascular system functions is the most important role in the aerobic exercise. Epidemiological studies and experimental studies have indicated that aerobic exercise not only can increase energy consumption, improve vitality lipoprotein and lower blood lipid content, but also can reduce blood pressure in patients with hypertension and decrease the incidence of arteriosclerosis and other cardiovascular diseases, and can effectively enhance cardiac function. CONCLUSION: Appropriate aerobic exercise can lead to the enhancements of cardiac function and vascular function, and plays an important role in the prevention and treatment of cardiovascular diseases.

Objective To investigate the expression of miR-133b in the brain of methamphetamine(MA) dependent rats and its regulatory effects on neuronal toxic injury.MethodsThrough continuous intraperitoneal injection to rats with MA(10 mg/kg),the conditioned place preference(CPP) rats model was established,and the expression of miR-133b in the cerebral cortex of model rats was detected by real-time fluorescence quantitative PCR(RT-PCR).PC12 cells were cultured in vitro and treated with MA(800 μmol/L),and then miR-133b expression in cultured neurons was detected.miR-133b mimics and inhibitor were transfected to PC12 cells respectively to observe the effect of miR-133b on the mitochondrial membrane potential(MMP) of cultured neurons.ResultsAfter continuous intraperitoneal injection with MA for 14 days,the residence time of rats in the box with medicine((620.20±44.80)s) was significantly longer compared with the control group((341.80±25.12)s,P<0.01),which showed that MA dependent rats model was successfully established.The RT-PCR detection results showed that the expression of miR-133b in the cerebral cortex of model rats(0.36±0.05) significantly decreased compared with the control group(0.99±0.08,P<0.01).In the in vitro model,most of the neuronal cell bodies became round and the neuorites were withdrawn after MA treatment.Compared with the control group(1.00±0.02),the RT-PCR detection results showed that the expression of miR-133b in MA group(0.74±0.05) decreased(P<0.05).The JC-1 detection results showed that the MMP of the MA group(109.85±7.03) decreased significantly contrast to the control group(36.49±3.89,P<0.01),the MMP of the miR-133b mimics group(58.97±6.56) increased significantly contrast to the mimics control group(135.46±15.04,P<0.01) and the MMP of the miR-133b inhibitor group(162.84±14.15) decreased contrast to the inhibitor control group(139.81±12.26,P<0.05).ConclusionsThe expression of miR-133b in the cerebral cortex of MA dependent rats and in vitro neuron model treated with MA are significantly downregulated.By regulating the expression of miR-133b,the MMP damage of cultured neurons treated with MA is changed,indicating that miR-133b is not only involved in the nerve injury induced by MA,but also possiblely as a molecular target for intervention.

A rapid headspace gas chromatography tandem mass spectrometric ( HS-GC/MS ) method was established for the analysis of volatile fatty acids ( VFAs ) in the feces. Feces were suspended by 6%phosphoric acid aqueous solution (1:2 m/V) and sealed in the headspace bottle for HS-GC/MS analysis. The HS-GC/MS method was optimized as follows: agitator temperature ( temp. ):80 ℃, syringe temp.:80 ℃, sample incubation time: 30 min, injection: 1 mL without split-flow. The chromatographic separation was performed on a DB-FFAP capillary column (30m×0. 25 mm×0. 25 μm) with injection port temp.:250 ℃. The temperature program ( initial temp. at 50 ℃ within first 1 min, and raised to 200 ℃ by 10 ℃/min) was employed by fixing the flow of carrier gas (high purity helium) at 1. 0 mL/min. The electron energy at -70 eV for electron impact ( EI ) ionization, ion source temp.: 250 ℃, transfer line temp.:280 ℃, the voltage of electron multiplier at 0. 95 kV. The spectra were recorded in the range of m/z 33-200 for full scan. The established HS-GC/MS method could be applied to analyze VGAs in the feces from human and rat appropriately. There are nine VFAs identified in the feces from human, and eight VFAs detected in the feces from rat by retrieving the NIST library, comparing with the standards and analyzing the MS data. Furthermore, the relative percentage contents of acetic acid, propionic acid and butyric acid accounted for roughly 85% of all VFAs by area normalization. The method is simple and sensitive, and it can be used to rapidly detect VFAs in the feces from human and rat.
