With water immersion, the water exerts a pressure on the body surface. Thus there is a blood volume shift from the periphery to the central circulation, resulting in marked volume loading of the thorax and heart. This article illustrated hemodynamic and hurohumoral responses of hydrotherapy, and dicussed whether patients with left ventricular dysfunction (LVD) or chronic heart failure (CHF) can immerse, take balneotherapy, exercise in the water and swimming. A positive effect of therapeutic warm-water tub bathing has been observed in patients with LVD and CHF, which was assumed to be from afterload reduction due to peripheral vasodilatation caused by the warm water. Optimal swimming as used for cardiovascular training programs may be allowed exclusively for NYHA class Ⅱ patients with myocardial infarction older than 6 weeks, myocarditis suffered more than 6 months ago, and cardiomyopathy. Patients with previous severe myocardial infarctions and/or CHF may bathe in a half sitting position, but immersed no deeper than the xiphoid process, because immersion up to the neck could produce abnormal increase in mean pulmonary pressure and pulmonary capillary wedge pressure temporarily. In coronary artery disease (CAD) patients with reduced LV function the heart is working more efficiently with mild cycling in water than cycling outside of water. Decompensated heart failure is the absolute contraindication to hydrotherapy.

The dysfunction of subthalamic nucleus is the main cause of Parkinson's disease. Local field potentials in human subthalamic nucleus contain rich physiological information. The present study aimed to quantify the oscillatory and dynamic characteristics of local field potentials of subthalamic nucleus, and their modulation by the medication therapy for Parkinson's disease. The subthalamic nucleus local field potentials were recorded from patients with Parkinson's disease at the states of on and off medication. The oscillatory features were characterised with the power spectral analysis. Furthermore, the dynamic features were characterised with time-frequency analysis and the coefficient of variation measure of the time-variant power at each frequency. There was a dominant peak at low beta-band with medication off. The medication significantly suppressed the low beta component and increased the theta component. The amplitude fluctuation of neural oscillations was measured by the coefficient of variation. The coefficient of variation in 4-7 Hz and 60-66 Hz was increased by medication. These effects proved that medication had significant modulation to subthalamic nucleus neural oscillatory synchronization and dynamic features. The subthalamic nucleus neural activities tend towards stable state under medication. The findings would provide quantitative biomarkers for studying the mechanisms of Parkinson's disease and clinical treatments of medication or deep brain stimulation.

Objective To investigate the effect of the eye-acupuncture therapy on serum TNF-α levels in rats with cerebral ischemia-reperfusion injury and the related mechanism. Methods Healthy SD rats were randomly divided into four groups: normal group, sham-operated control group, ischemia-reperfusion model group and eye-acupuncture group according to body weight. Sham-operated control group, ischemia-reperfusion model group and eye-acupuncture group were divided into the 3h group, the 24h group and the 72h group, a total of 10 groups (n=8). To establish the rat model of cerebral ischemia-reperfusion by suture method in ischemia-reperfusion model group and eye-acupuncture group. Eye-acupuncture was separately started immediately after reperfusion and at 30 min before sampling in the 3h eye-acupuncture group, besides, eye-acupuncture was separately taken every 12h in the 24h eye-acupuncture group and in the 72h eye-acupuncture group. The rats in normal group were not treated, those in sham-operated control group were inserted the fishing thread 1cm, and the others were identical with those in ischemia-reperfusion model group. At 3h, 24h, 72h after reperfusion, the neurophysical behaviours were accessed by ZeaLonga neurophysical impairment marks in ischemia-reperfusion model group and eye-acupuncture group. The method of ELISA was taken to detect the change of serum TNF-α levels in rats after the eye-acupuncture therapy. Results Compared with the ischemia-reperfusion model group, the neurologic impairment score of the eye-acupuncture group decreased obviously; The levels of serum TNF-αin ischemia-reperfusion model group at 3 h, 24 h, 72 h respectively were(76.803±18.325)pg/ml、(85.511±13.334)pg/ml、(86.831±9.232)pg/ml. The level of serum TNF-α in normal group was(24.304±6.511)pg/ml. The level of serum TNF-α in Sham-operated control group at 3 h, 24 h, 72 h respectively were(24.928±3.792)pg/ml,(27.533±5.362)pg/ml,(29.366±5.874)pg/ml. Ischemia-reperfusion model group compare with normal group and sham-operated control group, the difference were significant(P<0.01). The levels of serum TNF-α in rats after the eye-acupuncture therapy at 3 h, 24 h, 72 h respectively were(40.185±3.335)pg/ml, (48.523±7.687)pg/ml, (51.611± 6.403)pg/ml. Compared with ischemia-reperfusion model group, the levels of serum TNF-α were strongly reduced(P<0.01). Conclusion The eye-acupuncture therapy could play a role in improving cerebral ischemia-reperfusion injury evidently and the mechanism was related to its reducing serum TNF-α levels.

AIM: To observe the expressions of aquaporin 2 (AQP2) in kidney tissues and the contents of endotoxin (ET), interleukin-1 β (IL-1β), tumor necrosis factor-α (TNF-α) in serum in emphysema model rats, and to investigate the relationship between lungs and kidney in humoral metabolism. METHODS: The rats of emphysema were treated by injecting lipopolysaccharide into the trachea with cigarette smoking. Immunohistochemistry and Western blotting analysis were used to observe the expression of AQP2 in kidney tissues. RT-PCR was applied to detect the expression of AQP2 mRNA in kidney tissues. Blood sample and lung tissue were taken and the levels of ET, IL-1β and TNF-α were measured by radioimmunoassay. RESULTS: AQP2 expression in the kidney tissue in model group was greater than that in control group, and the expression of AQP2 mRNA showed the same results (P<0.01). ET, IL-1β and TNF-α levels in serum and lung tissue in model group were markedly higher than those in control group (P<0.01). CONCLUSION: In the emphysema model rats, AQP2 expression is up-regulated in the kidney tissue. The mechanism of emphysema may be related to increasing the levels of ET, IL-1β and TNF-α in the serum and lung tissue obviously.

Pathological neural activity in subthalamic nucleus (STN) is closely related to the symptoms of Parkinson' s disease. Local field potentials (LFPs) recordings from subthalamic nucleus show that power spectral peaks exist at tremor, double tremor and tripble tremor frequencies, respectively. The interaction between these components in the multi-frequency tremor may be related to the generation of tremor. To study the linear and nonlinear relationship between those components, we analyzed STN LFPs from 9 Parkinson's disease patients using time frequency, cross correlation, Granger casuality and bi-spectral analysis. Results of the time-frequency analysis and cross-frequency correlation analysis demonstrated that the power density of those components significantly decreased as the alleviation of tremor and cross-correlation (0.18-0.50) exists during tremor period. Granger causality of the time-variant amplitude showed stronger contribution from tremor to double tremor components, and contributions from both tremor and double tremor components to triple tremor component. Quadratic phase couplings among these three components were detected by the bispectral approaches. The linear and nonlinear relationships existed among the multi-components and certainly confirmed that the dependence cross those frequencies and neurological mechanism of tremor involved complicate neural processes.

Objective To examine the use of reperfusion strategies in elderly patients with acute myocardial infarction (AMI) and investigate the factors affecting its use. Methods This survey population consisted of 338 consecutive elderly patients with AMI( t65 years) who were admitted to the department of cardiology of Beijing Military General Hospital between December 2003 and November 2007. The patients were divided into two groups based on the receiving of reperfusion strategies : a reperfusion group ( n = 252) and a non-reperfusion therapeutic group ( n = 86). Qualitative data were compared between the two groups using Chi-square tests and multiple binary logistic regression was used to determine the relationship between various patient-related factors with the probability of choosing reperfusion therapies or not. Results About 74. 6% of the elderly patients with AMI recevied reperfusion strategies [62. 2% pereutaneons coronary intervention (PCI) and 12.4% thrembelysis]. Stepwise logistic regression analysis revealed that age ≥ 75 years( OR = 0. 255, P = 0. 000), history of angina ( OR = 0. 570, P = 0. 016 ) and high Killip classification ( OR =0. 671 ,P =0. 012) were confirmed factors for receiving less reperfusion therapy. Meanwhile, inferior wall myocardial infarction (MI) with complicating right ventricular MI( OR =4. 585,P =0. 002) ,sweating ( OR = 1. 970, P = 0. 016), unbearable symptoms ( OR = 1. 836, P = 0. 038 ) and medical insurance ( OR =1. 968,P =0. 029) were independent predictors for receiving reperfusion therapy. Intracranial hemorrhage (2.8% vs 7. 1%,P =0.000), left ventricular ejection time <45% (12% vs 31%,P =0.016) and mortality rate within 1 year(2. 3% vs 4. 7%, P = 0. 039) were obviously decreased in the PCI group as compared with the thrembelysis group. Conclusions Aging, medical history of angina, high Killip classification, inferior MI with complicating fight ventricular MI, sweating, unbearable symptoms and medical insurance were independent predictors for receiving reperfusion strategies.
