Abstract:
Proposed to investigate the effects of simulated weightlessness on cell area, cell multiplication and cell cycle of MG-63 cells. The rotating clinostat was used to simulate weightlessness. The change of cell area was measured with image processing and analysis soft (Image J). Cell growth curve was measured with cytometry. The change of cell cycle was examined with a flow cytometer. Compared with control group, the cell area of cell line MG-63 in 24 h,36 h and 48 h durations of rotating group decreased significantly (P<0.05). Compared with 12 h duration, the cell area in 24 h, 36 h and 48 h durations of rotating group decreased significantly (P<0.05). But in control group, cell area of all 4 experimental durations showed no significant difference among each other. Compared with control group, cell growth curve revealed that cell multiplication was inhibited in rotating group. Compared with control group, the cell cycles of cell line MG-63 in 12 h, 36 h, 48 h sections of rotating group did not change significantly, but the cell in 24 h duration of rotating group was decreased significantly (P<0.05) in G0 + G1 phase and increased significantly (P<0.05 ) in S phase. Simulated weightlessness in rotating clinostat may lead cell area of cell line MG-63 in 24 h, 36 h and 48 h durations to be decreased. Cell multiplication is inhibited in 12 h, 24 h, 36 h and 48 h durations. The conversion of cell from S phase to G2 phase is inhibited in 24 h duration.

Abstract:
Proposed to study the protective effects of Cudrania tricuspidata polysaccharides (CPS) and Lycium barbarium polysaccharides (LBP) on the cellular immune function in tail-suspended mice. Two dosages of CPS and LBP were orally administered to tail-suspended mice, respectively. Splenic T lymphocyte proliferation was determined by MTS colorimetric assay and cytokines production in supernatants obtained from cultured spleen cells after stimulation with ConA were detected by ELISA assay. Splenic T lymphocyte proliferation and the levels of IL-2 and IFN-gamma decreased significantly in tail-suspended mice 7 d later, which could be enhanced by administration of CPS. CPS has protective effects on cellular immunity of tail-suspended mice in simulated microgravity.

Abstract:
Proposed to explore the feasibility of estimating mean trabecular bone spacing (MTBS) by the improved cepstrum method. The improved cepstrum method based on an inverse filter is proposed in this paper. In order to test its performance, simulations were performed and bovine tibia cancellous bone specimens in vitro were used in our experiments. It is indicated that the improved cepstrum method can minimize the influence of transducer impulse response and tissue scatterer properties. It also can be easily implemented with little computation. Compared with traditional cepstrum, the improved cepstrum method has a more accurate MTBS estimate because of its less sensitivity to the variety of MTBS, diffuse scattering and noise.

Abstract:
Proposed to investigate the action of transcutaneous electrical acupoint stimulation to reduce fatigue, and to evaluate the countermeasure effect. Twelve-channel EEG signals (F3, F2, F4, C3, Cz, C4, P3, Pz, P4, O1, Oz, O21) were recorded in 9 young, healthy male volunteers under three conditions: normal, fatigue and after transcutaneous electrical acupoint stimulation. G values, the average power spectral densities, of delta, theta, alpha, beta EEG bands were calculated to analyze the EEG effect after transcutaneous electrical acupoint stimulation. G values of delta, theta, alpha, beta EEG bands and imbalance of G values of alpha EEG bands increased during fatigue, compared with those in the normal condition. G values of delta, theta, alpha, beta EEG bands and imbalance of G values of alpha EEG bands decreased after transcutaneous electrical acupoint stimulation. Transcutaneous electrical acupoint stimulation provides a positive countermeasure effect for fatigue as revealed by EEG.

Abstract:
Proposed to present a new application of the Hilbert-Huang transform method for automatic sleep stage classification. Instantaneous frequencies of sleep EEG with physical meaning and energy-frequency distribution used as feature parameters for each stage were computed with the Hilbert-Huang transform. Finally, the pattern recognition method of nearest neighbors was applied to optimal classification. Five hundred and sixty samples were picked from sleep EEG, and classification was made. The mean rate of accuracy was as high as 81.7%. Automatic sleep stage classification can be made effectively from features of sleep EEG by the Hilbert-Huang transform.

Abstract:
Proposed to design a head-up tilt (HUT) experimental system which is capable of measuring head blood pressure and its dynamic process, to enhance the efficiency of a HUT experiment. The head blood pressure was calculated by the individual-calibrated pulse wave transit time (PWTT) measured from the B point of the impedance cardiography (ICG) to the beginning point of the superficial temporal artery pulse wave. Based on the improved tilt bed, the HUT experimental system was designed to detect the dynamic blood pressure, ECG, phonocardiogram (PCG), respiration and ICG continuously. Finally, the system performance was examined by HUT experiments of three volunteers. Head blood pressure was calibrated with individual precise PWTT. The system detected physiological signals continuously and stably during HUT experiments and our preliminary results presented the minimum value, dynamic regulating process and overall level of head blood pressure. The system can exactly describe continuous, dynamic and transient process of head blood pressure during HUT experiments, which will provide more information about the regulation function of the cardiovascular system. It is possible to study the instant responses of the pilot to + Gz stresses in high-perfomance aircraft.

Abstract:
Nonlinear method was applied to the analysis of pulse rate variability (PRV) signal of healthy people and coronary disease patients to find the different features, which can be used to detect coronary disease invasively and monitor the process of the disease. Pulse waves of the healthy people and patients (18 subjects in each group) were sampled by photoplethysmographic (PPG) sensor. The detrended fluctuation analysis algorithm was applied to PRV series which extracted from PPG signals, and the scaling exponents of the two groups of signals were obtained. The average scaling exponents of the patients, i.e. short term alpha(exp 1) long term alpha(exp 2), and whole process alpha, were significantly lower than those of the healthy subjects. Detrended fluctuation analysis algorithm was applied to the PRV signal of the healthy subjects and coronary disease patients. It was found that the average scaling exponents of the patients, alpha(exp 1) , alpha(exp 2) and alpha, are significantly different from those of the healthy people. These findings suggest that a nonlinear index could be used to detect and monitor coronary disease non-invasively.

Abstract:
Proposed to compare responses of tolerance to lower body negative pressure (LBNP) in healthy women of different fitness levels. V02max was examined using a treadmill and a step-wise LBNP procedure to the maximum of -50 mmHg was applied. Twenty one healthy female volunteers were divided into group A, sitting employees (n=11, V02max 33.69 +/- 4.50 mL kg(exp -1) min(exp -1) and group B, pilots (n=10, V02max 39.61 +/- 3.84 mL kg(exp -1) min(exp -1). With the step-wise of LBNP, heart rate of all groups were gradually increased. Under -50 mmHg, heart rate (HR) increased significantly (P<0.01 to approximately 0.001), systolic blood pressure (SBP) of group B decreased significantly (P<0.01), diastolic blood pressure (DBP) of group A increased significantly (P<0.05) and mean blood pressure (MBP) of group B decreased significantly (P<0.05). It is indicated that those with better fitness have lower cardiovascular responses to LBNP.

Abstract:
Proposed to investigate the effects of heat stress on exercise tolerance and functions of protein metabolism changes in tail-suspended rats. Forty-six male SD rats were randomly assigned to 4 groups: exercise control group (Con) , exercise after tail-suspension group (ES), exercise under high temperature group (EHT) and exercise under high temperature after tail-suspension group (EHTS). The rats underwent exercise of increasing intensity until exhaustion under normal or 38 C environment after 14 d of tail suspension or Con. The running time and the increased rectal temperature after exercise were measured at the end of exhaustion. Blood samples were collected immediately after exercise to detect serum testosterone and cortisol concentrations. As compared with Con rats, the running time, serum testosterone concentrations and testosterone/cortisol ratio of ES rats, EHT and EHTS rats decreased significantly. As compared with Con rats, the serum cortisol concentrations showed no significant change in ES and EHT rats, and the concentrations increased significantly in EHTS rats. Running time, serum testosterone concentrations and testosterone/cortisol ratio of EHTS rats were significantly shorter or lower when compared with those of ES rats. The increases of rectal temperature and serum cortisol concentrations in EHTS rats were significantly higher than those in ES rats. Thermal stress(38 C) significantly decreases the exercise tolerance of tail-suspended rats, which might be related to the decrease of thermoregulation capability, intensification of catabolism and attenuation of anabolism.

Abstract:
Proposed to identify the model parameters of surface Electromyography (sEMG) by comparison between simulated and recorded signals. A physiological model of sEMG signal was established basing on several logical hypothetical conditions, such as motor unit action potentials (MUAP), motor unit recruitment and firing behavior caused by excitation, architecture of volume conductor and other simulated factors. According to the matched shapes between the simulated and recorded sEMG signals, a group of model parameters was obtained; according to the similar power spectrum variations of real sEMG signals, decreased muscle fiber conduction velocity (MFCV) was applied to simulate the sEMG signals of the fatigued muscle. The experimental results showed that the simulated superimposed MUAP shapes could be matched with the recorded MUAPs satisfactorily by adjusting some proper physiological parameters of the model. When the MFCV of each fiber was assumed to decrease, the mean and median frequency (MNF, MDF) of the simulated sEMG signals declined, and this phenomenon was very similar to that of the recorded sEMG signals and could be used to interpret the muscle fatigue process. This model provides an effective approach to simulate real sEMG signals, and the simulated signals can also be used to help the analysis of recorded sEMG signals.
