Aluminum is a common metal element,and its nervous toxicity probably has an effect on the learning and memory mechanism. Long-term potentiation (LTP) is an available electrophysiology-model,cAMP/protein kinase A (PKA) approach is an important signal transduction pathway of nerve cells,and plays an important role in the process of learning and memory mechanism. Aluminum has some adverse effects on learning and memory through influencing some links,such as neurotransmitter,Ca2 + concentration,protein kinase and so on. According to the recent studies in this field,in electrophysiology and biochemistry,the present paper reviewed the effects of aluminum on the learning and memory mechanism,as well as the role of cAMP/PKA approach.

OBJECTIVESince 1987, professor Wasserman displayed cardiopulmonary exercise test starting (CPET) data as 3 rows and 3 columns 9 panels plots. Although many changes and additions, there still are some important functional parameters were not shown in 9 panels. We want to display more.

METHODSThe 100 Hz sampling data of symptom-limited maximal limit CPET was used to calculate breath-by-breath data after per second cutting technique, and then to calculate the average value of 10 s data for graphic display.

RESULTSIn new 9 plots, panels (1) - (7) use time for the "X" axis, oxygen uptake, carbon dioxide elimination, loaded power, heart rate, systolic blood pressure, diastolic blood pressure, heart rate pressure product, minute ventilation, respiratory exchange ratio, CO2 elimination ventilatory efficiency, oxygen uptake ventilatory efficiency, oxygen pulse, ST segment level and ST segment slope at V5 lead, tidal volume, respiratory rate, end tidal oxygen partial pressure, end tidal carbon dioxide partial pressure and oxygen saturation of 18 noninvasive parameters, and arterial oxygen partial pressure, arterial oxygen saturation, arterial partial pressure of carbon dioxide 3 blood gas parameters for the "Y" axis respectively. There are 3 vertical dashed lines represent dividing lines of the resting, warm-up, incremental power loading exercise and recovery period respectively. In addition, panels (1) and (4) have the horizontal dashed line represents the maximal oxygen uptake (red), oxygen uptake efficiency plateau (red) and the lowest value of carbon dioxide elimation ventilatory efficiency (blue) expected value respectively. Panel ( used heart rate and carbon dioxide elimination (as Y) against to oxygen uptake (as X); the "+" indicates intersection of the predicted maximum values of oxygen uptake and heart rate. Panel (9) used tidal volume (as Y) against over minute ventilation (as X), vertical dashed line is the measured maximum ventilatory volume, the horizontal dashed lines were the inspiratory capacity and vital capacity respectively.

CONCLUSIONNew CPET 9 plots emphasizes on the integration of all circulatory, respiratory and metabolic etc functional parameters in human, and is conductive to optimization of clinical medical service and health management.

The cardiopulmonary exercise testing (CPET) is one important clinical functional testing method, which linked to all functions of respiratory, circulatory, metabolic and neurohumoral etc. The most important parameter of CPET is oxygen uptake which can reflect the core oxygen metabolic information of the human being's holistic integrative physiology. We explain why the CPET interpretation needs new philosophy of holistic integrative physiology and medicine. CPET is a unique holistic, objective, quantitative scientific evaluation skill of human function to distinguish health, sub-health and dieases, It can help us to make optimal recommendations for prevention, diagnosis and differential diagnosis, treatment evaluation, exercise rehabilitation and prognosis of many clinical diseases. However, in order to so, we needs pre-qualified and calibrated stable system, standardized clinical practice, data analysis, display illustration and interpretation principle for CPET.

OBJECTIVEFrom the point of holistic integrative medicine, the D(L)CO depends on not only normal respiratory and circulatory functions, but also an optional matching between them. However, due to the limitation of traditional systemic physiology, the D(L)CO always be classified as lung functional parameter to be analyzed and interpreted. Because ignoring the circulatory system function, so it will certainly have some misunderstandings.

METHODSBased on the Holistic Integrative Medicine, under the control of neurohumoral, respiratory, circulatory and metabolic systems work together, we discussed the diffusion function. We analyzed the change of D(L)CO in the patients with cardiac dysfunction, especially the heart failure.

RESULTSThe D(L)CO, CO gas,diffusion from lung circulating blood, depends on the normality of respiratory and circulatory systems and their matching. We analyzed the reasons of D(L)CO for characteristic pathophysiological changes of patients with heart failure.

CONCLUSIONThe normal D(L)CO depends on a good matching of normal respiratory and circulatory systems. For heart failure, the respiratory and circulatory systems matching is poor. Due to dominant limitation of left ventricle pump function, pulmonary blood volume may slightly increased, but combination of all reduced pulmonary blood flow rate, thicked diffuse member and increased diffusion distance etc. suggest that patients with heart failure should have a decreased, rather than increased, D(L)CO.

OBJECTIVESystemic mechanism of neurohumoral control and regulation for human is limited.

METHODSWe used the new theory of holistic integrative physiology and medicine to approach the mechanism and pattern of neurohumoral control and regulation for life.

RESULTSAs the core of human life, there are two core axes of functions. The first one is the common goal of respiration and circulation to transport oxygen and carbon dioxide for cells, and the second one is the goal of gastrointestinal tract and circulation to transport energy material and metabolic product for cells. These two core axes maintain the metabolism. The neurohumoral regulation is holistically integrated and unified for all functions in human body. We simplified explain the mechanism of neurohumoral control and regulation life (respiration and circulation) as the example pattern of sound system.

CONCLUSIONBased upon integrated regulation of life, we described the neurohumoral pattern to control respiration and circulation.

OBJECTIVEThe interpretation of control and regulation of circulatory parameters in traditional physiology has some limitations. Human being is an organic, circulatory control and regulation should involve all the systems.

METHODSBased upon the theory of holistic integrative physiology and medicine, we approach to explain the circulatory control and regulation from its purpose.

RESULTSThe main purpose of circulation is to maintain a stable metabolism of cells, i.e. transport oxygen (from lung) and nutrients (from gastrointestinal tract) to cells, and return carbon dioxide and metabolic products back for elimination. Based on this goal, all respiration and gastrointestinal digestion, absorption, urinary excretion, etc. are integrative together for regulation to maintain the supply-demand balance at any metabolic status of resting, exercise and sleep. So that, we can explain many existing problems and questions, for example: why and how the foramen ovale closed after birth; mechanism of Cheyne-Stokes respiration; blood flow redistribution during exercise; variabilities of systolic blood pressure, heart rate and autonomic tone.

CONCLUSIONThe circulatory control and regulation is the integration of all systems of the body.

OBJECTIVEThe modern systemic physiology, based on limit-understand functional classification, has significant limitation and one-sidedness. Human being is organic; we should approach the mechanism of control and regulation of breathing integrating all the systems.

METHODSWe use new theory of holistic integrative physiology and medicine to explain the mechanism of control and regulation of breathing.

RESULTSExcept the mean level information, the up-down "W" waveform information of arterial blood gas (ABG) is core signal to control and regulate breathing. In order to do so, we must integrate all systems together. New theory will help to explain some unanswered questions in physiology and medicine, for example: fetal does not breathing; how first breath generate; how respiratory rhythm and frequency generate, etc.

CONCLUSIONBreathing is the sign of life. Mechanism of control and regulation of breathing has to integrate respiration, circulation, nerves, metabolism, exercise, sleep and digestion, absorption and elimination and etc altogether.

Under background of reductionism in the modern science, physiology and medicine are stepwise refined into system, organ, disease, cell and gene etc. Although clinical medicine, only service in whole human object, obviously brought tremendous progress, it also appeared obvious defects and limits at the same time. Professionalized and specialized medicine not only needs to be integrated from basics to clinical fields, but also from prevention, health management, clinical treatment and functional rehabilitation medicine. People are indivisible organic whole. Professionalization, translation and integration must be combined. In order to provide the best quality and optimized medical service for the Chinese people and to lead in the world, we have to strengthen professional and technical knowledge, and have to establish the holistic integrative medical philosophy for physiology and medicine too.

DNA double strand breaks are potentially lethal DNA lesions induced by ionizing radiation, which can be repaired by homologous recombination and non- homologous end joining. Inhibition of the expression and function of genes in double strand breaks repair pathways using RNA interference and anti- sense techniques could improve the radiosensitivity of cancer cells.

Egr-1 is a radiation-inducible transcription factor. It was demonstrated that the regulatory sequence in 5' flanking region of Egr-1 gene could confer the radiation inducibility upon a tumoricidal gene to which it was linked, and was consequently used in experiments on the gene-radiotherapy to tumor. As a first step to test the possibility, we have isolated the 445 bp-long regulatory sequence of Egr-1 gene from BALB/c mouse gcnomic DNA with PCR method. Sequence analysis confirmed that nucleotide sequence of this cloned fragment was identical with one reported previously with only one base difference in A to G substitution at residue - 392, and had six CC( A + T)6GG domains which were essential to the radiation-inducible property of Egr-1 gene. This fragment then was inserted into the Mlu I-Bgl II site of pGL3, a reporter vector containing luciferase gene. The constructs were used to transfect mouse malignant melanoma cells (B16) to characterize the regulatory function of this CC ( A + T)_(6)GG-rich sequence after exposure to r-radiation by a ~(60) Co source. The results indicate that the activity of luciferase in transfectant increases by 138% as compared with control levels, demonstrating that r-radiation inducibility of gene expression can be conferred by the regulatory sequence.
