ObjectiveTo investigate the effects of Tai Chi exercise on somatic function of middle-aged females.Methods60 middle-aged females had a 16-week Taichi quan exercise and changes of blood pressure, resting heart rate and vital capacity were tested.ResultsAfter Tai Chi exercise, 60 women had results of resting heart rate and blood pressure decreased, and vital capacity increased obviously (P<0.05～0.01).ConclusionTai Chi exercise maybe an effect sport manner to improve the somatic function of middle-aged females.

OBJECTIVETo verify the regulatory effects of acupuncture on exercise tolerance in patients with chronic obstructive pulmonary disease (COPD) at stable phase.

METHODSThirty cases of COPD were randomly divided into a treatment group (16 cases) and a placebo group (14 cases). Based on specified aerobic exercise, acupuncture was applied in the treatment group and placebo acupuncture was used in the placebo group. The acupoints included Danzhong (CV 17), Rugen (ST 18), Guanyuan (CV 4), Zhongwan (CV 12), Tianshu (ST 25) and so on. The needle did not penetrate into the skin for the placebo group. The treatment was required for 2 to 3 times per week for totally 5 weeks. The indices of exercise tolerance, including 6-min walking distance (6-MWD), exercise time, maximum oxygen uptake (VO2max) forced expiratory volume in 1 second (FEV1)/forced vital capacity (FVC), maximum ventilatory volume (MVV), St. George respiratory questionnaire (SGRQ) were observed in two groups before and after treatment.

RESULTS(1) Exercise tolerance: the differences of 6-MWD and exercise time were statistically significant between groups, which were more superior in the treatment group (both P<0.01); the VO2max was significantly increased after treatment in the treatment group (P<0.05), but there was no difference between two groups (P>0.05). (2) Pulmonary ventilation function: the differences of FEV1%, FEV1/FVC and MVV% were statistically significant between groups, which were more superior in the treatment group (P<0.05, P<0.01); (3) SGRQ: the SGRQ was significantly improved after treatment in the treatment group (P<0.05), but there was no difference between two groups (P>0.05).

CONCLUSIONThe acupuncture could improve the exercise tolerance in patients with chronic obstructive pulmonary disease at stable phase, and shorten the onset time of aerobic exercise. Besides, acupuncture combined with aerobic exercise could effectively improve the pulmonary function.

In this study, five rhesus macaques were inoculated intravenously with SIVmac251 to establish a model of simian autoimmune deficiency syndrome (SAIDS). Peripheral blood samples were collected at different time points to monitor changes in the total T cell number and T lymphocyte subset. Plasma viral loads, cytokine expression levels and anti-SIV antibody levels were also assayed to acquire certain basic indexes to evaluate disease progression in the rhesus macaque SAIDS model. During the acute stage of infection, plasma viral loads reached a peak at week 1 post-inoculation and lasted for approximately 3 to 44 weeks. The CD3+ CD4+ T lymphocyte count in peripheral blood also transitorily decreased. During the same period, the level of interferon-gamma show an increasing trend, whereas IL-12 levels decreased; IL-2, IL-4, IL-10 and TNF-alpha were maintained at normal levels or could not be detected. During the asymptomatic and ARC phases, plasma viral loads persisted above 10(4) RNA copies/mL and either increased or declined during the later stages of disease; CD3+ CD4+ counts showed a steadily declining trend and the ratio of CD4 to CD8 decreased during late-stage disease. Moreover, antibodies against viral proteins were detected in the plasma and showed a significant increasing trend, while there were no apparently changes in the levels of IFN-gamma, IL-12, IL-2, IL-4, IL-10 and TNF-alpha. In conclusion, the characteristics of the SIV animal models in our study are similar to those of patients with AIDS. Therefore, the rhesus macaque SIVmac251 infection models can be applied for further studies into AIDS.

In this study, the human umbilical vein endothelial cell model was used to study the regulating effect of lipophilic components in Salvia miltiorrhiza on angiogenesis, and explore its possible mechanism. The cell model was established to determine the effect of lipophilic components in S. miltiorrhiza on the proliferative activity and migration capacity of endothelial cells. Then the realtime fluorescence quantification PCR technology was applied to detect the changes in the gene expressions of angiogenesis-related cytokines VEGF-A, VEGF-C and MMP-9. The results showed that 5 mg x L(-1) lipophilic components in S. miltiorrhiza could inhibit the proliferation and migration of endothelial cells, and reduce the expression of VEGF-A and MMP-9 genes. It indicated that lipophilic components in S. miltiorrhiza may inhibit the proliferation and migration of endothelial cells by inhibiting the expression of VEGF-A and MMP-9 genes, so as to show the inhibitory effect on angiogenesis.

The pediatrician training system includes four levels of construction mode:the pediatric professional training for general practitioner, general pediatric professional training, pediatric skills training of community in-service physicians and pediatric continuing education for general pedestrians by Pediatric Professional Committee. Standardized and homogeneous training will help to improve children's health service system and change the current shortage of pediatric clinicians at the primary level.
