Objective: To explore and study the clinical usefulness of continuous dynamic recording of left cardiac function changes forevaluation the improvement in patients with chronic disease after 3 months of intensive control of individualized precision exercise overall manage program. Methods: From 2018 to 2021, 21 patients with chronic cardiovascular and cerebrovascular metabolic diseases mainly controlled by our team were selected to complete the cardiopulmonary exercise test (CPET) and Non-invasive synchronous cardiac function detector (N-ISCFD), electrocardiogram, radial pulse wave, jugular pulse wave and cardiogram data were continuously recorded for 50s.According to the titration results under CPET and continuous functional parameters monitoring, a holistic plan with individualized moderate exercise intensity as the core was developed for 3 months of intensive management, and then N-ISCFD data collection was repeatedafter signing the informed consent. All N-ISCFD data were analyzed in the 50s according to the optimal report mode of Fuwai Hospital and 52 cardiac functional indexes were calculated. The data before and after the enhanced control were compared and the paired T-test was used to statistically analyze the changes of groups. Results: Twenty-one patients with chronic diseases (16 male and 5 female) were (54.05±12.77,29~75) years, BMI (25.53±4.04,16.62~31.7) kg/m2.Comparison with baseline,the whole group analysis: ①The body weight, BMI, systolic blood pressure and diastolic blood pressure of patients were significantly decreased(P＜0.01).②CPET Peak VO2 was (64.93±24.22, 26.96~103.48) %Pred before enhanced control, and (85.22±30.31, 43.95~140.48) %Pred after enhanced control, and increased (35.09±27.87, 0.12~129.35) % after enhanced control compared with before enhanced control. The AT, Peak VO2/HR, Peak Work Rate, OUEP, FVC, FEV1, FEV3/FVC% and MVV were significantly increased (P＜0.01) and the Lowest VE/VCO2 and VE/VCO2 Slope were significantly decreased(P＜0.01).③Core indicators of left heart function:Ejection fraction was significantly increased from (0.60±0.12,0.40~0.88) to(0.66±0.09, 0.53~0.87)(P＜ 0.01), by (12.39±14.90,-12.32~41.11)%. The total peripheral resistance was significantly decreased from (1579.52±425.45,779.46~2409.61) G/(cm4·s),to(1340.44±261.49,756.05~1827.01) G/(cm4·s)(P＜0.01), by (12.00±17.27,37.79~28.61) %.The left stroke index, cardiac total power, ejective pressure and left ventricular end diastolic volumewere significantly improved (P＜0.05).The change analysis of each indicator for each patient is shown in the individualized analysis section of this study. Conclusion: Use CPET and continuous functional monitoring we can safely and effectively develop the overall program of individualized exercise in patients with chronic diseases. Long-term intensive management and control can safely and effectively significantly improve the cardiovascular function of patients. Continuous dynamic recording of changes in left and right cardiac functional parameters can be a simple way to supplement CPET to evaluate cardiovascular function.

[Preliminary experimental study on the influence of different tidal volume and frequency of normal minute ventilation on the dynamic changes of carotid blood oxygen in living goats].

Objective: On the basis of preliminarily verifying the use of ultra-fast reaction polymer matrix optical fiber oxygen sensor and its measuring system to record the continuous and dynamic changes of carotid artery oxygen partial pressure (PaO2), in order to analyze and discuss the influence of lung ventilation on the continuous and dynamic changes of PaO2, we designed a whole animal experimental study in vivo. Methods: Four hybrid goats were selected, and the skin was cut and exposed directly under general anesthesia and tracheal intubation. The oxygen sensor, connected with the measuring system, was inserted directly into the left carotid artery to continuously record the dynamic changes of PaO2. With normal minute ventilation,mechanical ventilation is implemented through three tidal volumes: normal tidal volume (VT=15 ml/kg, Rf=20 bpm), half tidal volume (halved VT, doubled Rf) and double tidal volume (doubled VT, halved Rf). Each tidal volume was stable for 10~15 min respectively. We analyzed and calculated the average values of PaO2, the fluctuation magnitudes of PaO2 changes between breaths of last 180 s and the delay times of lung-carotid artery were. We analyzed the effects of different tidal volumes. Results: The heart rate and blood pressure of living goats were maintained stable during the mechanical ventilation experiment with normal ventilation volume Lung-carotid artery delay time is 1.4~1.8 s (about 3 heartbeats at this time). Under normal tidal volume of mechanical ventilation, the average value of PaO2 was (102.94±2.40, 99.38~106.16) mmHg, and the fluctuation range was (21.43±1.65, 19.21~23.59) mmHg, accounting for (20.80± 1.34, 18.65~22.22)% of the average value. Under the condition of halving tidal volume, the average value of PaO2 was maintained at (101.01±4.25, 94.09~105.66) mmHg, which was slightly decreased but not significant (P>0.05 compared with normal mechanical ventilation), but the fluctuation range of PaO2 was significantly reduced to (18.14±1.43, 16.46~20.05) mmHg, accounting for 17.5% of the average value. Under double tidal volume mechanical ventilation, although the average value of PaO2 increased slightly remained at (106.42±4.74, 101.19~114.08) mmHg (P>0.05 compared with normal mechanical ventilation and P<0.05 compared with half tidal volume mechanical ventilation), the fluctuation magnitude of PaO2 increased significantly to (26.58±1.88, 23.46~28.46)mmHg. Conclusion: Inspiration and expiration of normal lung ventilation are the initial factors for the increase and decrease of PaO2 in carotid artery. Under normal ventilation, halving tidal volume and doubling tidal volume significantly changed the fluctuation magnitude of PaO2, but the average value of PaO2 changed only slightly, while the lung-carotid delay time was similar.

[The characteristics of core parameters during cardiopulmonary exercise testing in patients with hypertrophy cardiomyopathy].

Objective: The patients with Hypertrophic CardioMyopathy (HCM), characterized by hypertrophy of the myocardium with a high risk of sudden death, was less clear for the exercise pathophysiology. Under the guidance of holistic integrative physiology and medicine (HIPM), the ramp protocol symptom-limited CardioPulmonary Exercise Testing (CPET) is the only method to evaluate the overall functional status of human body. We investigated the CPET pathophysiology in patients with HCM. Methods: From April 2017 to January 2020, 244 subjects were enrolled after signed the informed consent form and completing CPET in Fuwai Hospital. They 219 HCM patients and 25 healthy normal subjects as control (NS). The changes of CPET core parameters between two them were calculated, compared and did Individual analysis. Results: ①The gender of HCM was 163 maleand 56 female. The gender of NS was 11 male and 14 female. The age of HCM was (46.7±12.8, 16.0~71.0) year; NS was (43.7±10.4, 26.0~61.0) year.②The core CPET parameters of HCM: peak oxygen uptake (Peak VO2) was (65.2±13.8, 22.8~103.4) %pred; anaerobic threshold (AT) was (66.4±13.0, 33.7~103.5) %pred; Peak O2 pulse was (84.3±19.0, 90.9~126.0)%pred; oxygen uptake efficiency platform (OUEP) was (99.2±13.4, 69.1~155.5) %pred; Lowest VE/VCO2 was (108.0±13.2, 70.4~154.0)%pred; VE/VCO2 Slope was (108.5±17.9, 66.9~164.9)%pred. Compared with NS, the Peak VO2, AT, Peak O2 pulse, and OUEP were significantly decreased (P<0.01 or P<0.05), but the Lowest VE/VCO2 and VE/VCO2 Slope were significantly increased (P<0.05). For Individual analysis of the overall functional status of CPET, some were very sever but some HCM were still within the normal range.③ The Peak VO2 was positively correlated with AT, OUEP, Peak O2 pulse, and peak systolic blood pressure, but was negative correlated with Lowest VE/VCO2 and VE/VCO2 Slope. Conclusion: CPET is safe and specific characteristics for patients with HCM, which deserve further research and clinical application. Under HIPM guidance, CPET can not only be used for overall functional evaluation, disease diagnosis and differential diagnosis, risk stratification, curative effect evaluation and accurate prognostic prediction, but also be utilized in formulating the individualized training prescription and management of chronic diseases.

[The impacts of outpatient vs inpatient holistic management based on exercise training on cardiac rehabilitation efficacy among patients with chronic heart failure].

Objective: To evaluate the impacts of outpatient vs inpatient exercise training (ET) on cardiac rehabilitation efficacy among patients with chronic heart failure (CHF). Methods: Thirty six patients who were diagnosed with CHF in Beijing Rehabilitation Hospital from September 2015 to September 2018, were randomly divided into three groups: control group (n=12), outpatient ET group (n=12) and inpatient ET group (n=12). Patients in control group were treated with conventional cardiac rehabilitation without ET, patients in outpatient and inpatient ET groups were treated with holistic cardiac rehabilitation with the core of ET according to individualized exercise prescription based on cardiopulmonary exercise testing (CPET). Exercise intensity of cycle ergometer was Δ50% power above anaerobic threshold (AT), 30 min/d, 5 d/week, for 12 weeks. General information, CPET parameters, echocardiogram, 6 minute walking distance (6MWD) and quality of life (QoL) score of three groups of patients before and after treatment were recorded. Results: All patients in 3 groups finished symptom-limited CPET and patients in ET groups finished 12 weeks - ET safely without complications. Before treatment, there were no significant differences in CPET parameters, echocardiogram results, 6MWD and QoL score among 3 groups (P>0.05). After treatment, AT (ml/min, ml/(min·kg), %pred), peak oxygen uptake (VO2) (ml/min, ml/(min·kg), %pred), peak oxygen pulse(ml/beat), peak workload(W/min, %pred), left ventricular ejection fraction (LVEF) and 6MWD of patients in outpatient and inpatient ET groups were significantly higher than those of patients in control group (P<0.05), QoL score of patients in outpatient and inpatient ET groups was lower than that of patients in control group(P<0.05). To be noted, there were no obvious differences in CPET indexes, echocardiogram results, 6MWD and QoL score in patients between outpatient ET group and inpatient ET group (P>0.05). For patients in control group, there were no significant differences in above parameters before and after treatment (P>0.05). AT(ml/min, ml/(min·kg)), Peak VO2 (ml/min, ml/(min·kg), %pred), peak oxygen pulse(ml/beat, %pred), peak workload(W/min, %pred), LVEF and 6MWD of patients in outpatient and inpatient ET groups were significantly higher than those before treatment (P<0.05), QoL score of patients in outpatient and inpatient ET groups after treatment was significantly lower than that before treatment (P<0.05). Conclusion: Outpatient ET can improve the cardiopulmonary function, exercise tolerance and QoL of CHF patients, which has no significant difference compared with inpatient ET, indicating that outpatient cardiac rehabilitation, as an effective rehabilitation mode, is deserved to be applied widely.

[Ultra-fast response polymer optical fiber oxygen measurement device and its preliminary experimental report on continuous dynamic change of arterial oxygen partial pressure under mechanical ventilation in living animals].

Objective: We tried to implant the ultra-fast polymer optical fiber chemical oxygen sensor （POFCOS） into arterial blood vessel,connect with photoelectric conversion measurement system to record the continuous dynamic rapid changes of arterial PO2(PaO2) in whole living animals. It should be the experimental evidence for the new theory of holistic integrative physiology and medicine(HIPM) forexplain the mechanism of respiratory control and regulation in whole circusof respiration-circulation-metabolism. Methods: ①Fabrication of ultrafast POFCOS, calibration and its measuring system: The distal part of 2 m optical fiber was heated and pulled until it became a tapered tip. After cleaning and drying, the tip of 1 mm tapered optical fiber was dip-coated into the luminophore doped polymer solution, then was slowly pumped out while solvent was quickly evaporated to form an oxygen sensing tip, which was dried at room temperature for 24 hours. ②Animal experiments: Under general anesthesia and intubation, goatwas mechanically ventilated with 40%~60% oxygen. We exposed both right and left carotid arteries and the left femoral artery by skin cutting, and inserted the POFCOS directly into the arteries via indwelling catheter. The end of POFCOS were connected to the personal computer through optical fiber, excitation and detection Y-type optical fiber coupler through photoelectric conversion, so as we can realize the continuous dynamic response of living goat carotid PaO2 under mechanical ventilation. We mainly analyzed the intra-breath wave-form alternate increase and decrease of PaO2 and their time delay between lung and carotid arteries.We completes breathing control whole loop to explain the mechanism of mutual breathing and the switching of inspiration and exhalation. Results: The POFCOS has a very fast T90 response time was set 100 ms for liquid. When the heart rate of 40%~60% oxygen mechanical ventilated living goat was ~110 bpm, the PaO2 of left and right carotid artery showed a same wave-sizeup and down following with the inspiration and expiration of ventilator, with a range of up to 15 mmHg. There weresignificant noises of PaO2 change recorded in the left femoral artery. The lung-carotid artery time delay is 1.5~1.7 s after inhalation and exhalation, PaO2 at both left and right carotid arteries starts toincrease and decrease. After two-three heartbeats after the start of lung ventilation, thealternate up-down wave-form information of the arterialized pulmonary vein blood after pulmonary capillaries waspumpedby left ventricle to the position of peripheral chemoreceptors,thus realizing the whole cycle of inhalation and exhalation. It alternately interrupted inhalation, i.e. switching inhalation to exhalation, and then interrupted exhalation,i.e. switching exhalation to inhalation. Conclusion: The ultra-fast reactive implantableoxygen sensor and its measuring system can measure the physiological waveform changes of PaO2 in living animals, which can provide experimental evidence for explaining the mechanism of switching of inspiration-expiration in HIPM.

[A preliminary report on the variation of respiratory heart rate during sleep in normal subjects and patients with chronic diseases without sleep apnea].

Objective: The new theory of holistic integrative physiology and medicine, which describes the integrative regulation of respiratory, circulatory and metabolic systems in human body, generates the hypothesis of that breath is the origin of variability of circulatory parameters. We investigated the origin of heart rate variability by analyzing relationship between the breath and heart rate variability (HRV) during sleep. Methods: This retrospective study analyzed 8 normal subjects (NS) and 10 patients of chronic diseases without sleep apnea (CDs-no-SA). After signed the informed consent form, they performed cardiopulmonary exercise testing (CPET) in Fuwai Hospital and monitored polysomnography (PSG) and electrocardiogram (ECG) during sleep since 2014. We dominantly analyzed the correlation between the respiratory cycle during sleep and the heart rate variability cycle of the ECG R-R interval. The HRV cycle included the HR increase from the lowest to the highest and decrease from the highest to the lowest point. The number of HRV (HRV-n), average HRV time and other parameters were calculated. The breath cycle included complete inhalation and subsequent exhalation. The number of breath (B-n), average breath time and other breath parameters were analyzed and calculated. We analyzed each person's relationship between breath and HRV; and the similarities and differences between the NS and CDs-no-SA groups. Independent sample t test was used for statistical analysis, with P<0.05. Results: CPET core parameter such as Peak VO2 (83.8±8.9)% in NS were significantly higher than that (70.1±14.9)% in patients of chronic diseases without sleep apnea (P<0.05), but there was no difference between their AHI (1.7±1.3) in NS and AHI (2.9±1.2) in CDs-no-SA (P>0.05). The B-n and the HRV-n (6581.63±1411.90 vs 6638.38±1459.46), the average B time and the average HRV time (4.19±0.57)s vs (4.16±0.62)s in NS were similar without significant difference (P>0.05). The comparison of the numbers in CDs-no-SA were the number (7354.50±1443.50 vs 7291.20±1399.31) and the average times ((4.20±0.69)s vs (4.23±0.68)s) of B and HRV were similar without significant difference (P>0.05). The ratios of B-n/HRV-n in NS and CDs-no-SA were (0.993±0.027 vs 1.008±0.024) and both were close to 1 and similar without significant difference (P>0.05). The average magnitude of HRV in NS ((5.74±3.21) bpm) was significantly higher than that in CDs-no-SA ((2.88±1.44) bpm) (P<0.05). Conclusion: Regardless of the functional status of NS and CDs-no-SA, there is a similar consistency between B and HRV. The origin of initiating factors of HRV is the respiration.

[Preliminary analysis of the influence of breathing on heart rate variability in chronically ill patients with sleep apnea].

Objective: Based on the hypothesis that respiration causes variability of circulatory indicators proposed by the holistic integrated physiology and medicine theory, the correlation between respiration and heart rate variability during sleep in chronically ill patients with abnormal sleep breathing is analyzed. Methods: Eleven chronically ill patients with abnormal sleep breathing and apnea-hypopnea index (AHI) ≥15 times/hr are recruited. After signing the informed consent, they completed the standardized symptomatic restrictive extreme exercise cardiopulmonary exercise testing (CPET) and sleep breathing monitoring Calculate and analyze the rules of respiratory nasal airflow and ECG RR interval heart rate variability during the oscillatory breathing (OB) phase and the normal steady breathing phase of the patient during sleep, and use the independent sample t test to compare with normal people and no sleep breathing abnormalities in the same period in this laboratory. Of patients with chronic diseases are more similar and different. Results: The peak oxygen uptake and anaerobic threshold (AT) of CPET in chronic patients with abnormal sleep apnea were (70.8±13.6)% Pred and (71.2±6.1)% Pred; 5 cases of CPET had exercise induced oscillatory breathing (EIOB), 6 An example is unstable breathing, which indicates that the overall functional status is lower than normal. In this group of patients with chronic diseases, AHI (28.8±10.0) beats/h, the ratio of the total time of abnormal sleep breathing to the total time of sleep (0.38±0.25); the length of the OB cycle (51.1±14.4)s. The ratio (Bn/HRV-B-n) of the number of breathing cycles in the normal and steady breathing period to the number of heart rate variability cycles in this group of patients with chronic diseases is 1.00±0.04, and the CV (SD of HRV-B-M/x) is (0.33 ±0.11), blood oxygen saturation (SpO2) did not decrease significantly, the average amplitude of heart rate variability (HRV-B-M) of each respiratory cycle rhythm was (2.64±1.59) bpm, although it was lower than normal people (P<0.05) , But it was similar to chronic patients without sleep apnea (P>0.05). In this group of patients with chronic diseases, the ratio of the number of respiratory cycles to the number of heart rate variability cycles (OB-Bn/OB-HRV-B-n) during OB is (1.22±0.18), and the average amplitude of heart rate variability for each respiratory cycle rhythm in OB (OB -HRV-B-M) is (3.56±1.57)bpm and its variability (OB-CV = SD of OB-HRV-B-M/x) is (0.59±0.28), the average amplitude of heart rate variability in each OB cycle rhythm (OB-HRV-OB-M) is (13.75±4.25)bpm, SpO2 decreases significantly during hypoventilation during OB, and the average decrease in SpO2 during OB (OB-SpO2-OB-M) is (4.79±1.39)%. The OB-Bn/OB-HRV-B-n ratio, OB-HRV-OB-M and OB-SpO2-OB-M in the OB period are all significantly higher than the corresponding indicators in the normal stable breathing period Large (P<0.01). Although OB-HRV-B-M has no statistically significant difference compared with HRV-B-M in normal stable breathing period (P>0.05), its variability OB-CV is significantly increased (P<0.01). Conclusion: The heart rate variability of chronic patients with abnormal sleep breathing in the OB phase is greater than that of the normal stable breathing period. When the breathing pattern changes, the heart rate variability also changes significantly. The number of breathing cycles in the stable breathing period is equal to the number of heart rate variability cycles.The ratio is the same as that of normal people and chronically ill patients without sleep apnea, confirming that heart rate variability is respiratory origin; and the reduction of heart rate variability relative to the respiratory cycle during OB is directly caused by hypopnea or apnea at this time, and heart rate variability is also breathing source.

[Clinical study on the characteristics of exercise pathophysiological in patients with severe heart failure].

Objective: The cardiopulmonary function of patients with chronic heart failure (CHF) was severely limited, but the holistic integrative exercise pathophysiology is still unclear. Methods: After signed the consent form, Eighty three patients with severe CHF from October 2016 to October 2017 in Fuwai Hospital were performed Ramp incremental loading program CardioPulmonary Exercise Testing (CPET), and 12 normal subjects served as control. CPET were performed according to standard of Harbor-UCLA MC and the circulatory, respiratory and metabolic parameters during CPET were measured and analyzed. Results: Peak oxygen uptake (Peak VO2) in CHF (14.33±2.69) ml/(min·kg), (44.25±14.74)%pred was significantly lower than control ((29.42±5.46) ml/(min·kg), (83.88±6.28)%pred). Other core parameters of CPET such as anaerobic threshold (AT), peak oxygen pulse, oxygen uptake efficiency platform (OUEP), the lowest of carbon dioxide output ventilation ratio (Lowest VE/VCO2), and carbon dioxide output ventilation slope (VE/VCO2 Slope) in CHF were significantly different with the control group(P<0.01). The core parameters of lung function, such as forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC, and carbon monoxide diffusion (DLCO) were significantly decreased (P<0.01). Systolic blood pressure during all stages of CPET in CHF was significantly lower than control group (P<0.05); Heart rate at AT, peak and recovery stages were significantly lower than control (P<0.01). Minute ventilation, tidal volume and respiratory frequency at rest, warm-up were significantly higher than control (P<0.05). Tidal volume at recovery was significantly higher than control (P<0.05). VO2 at AT, peak and recovery stages in CHF were significantly higher than control (P<0.01). Oxygen pulse at AT and peak were significantly higher than control (P<0.01). Pulse oxygen saturation during all stages of CPET in CHF were significantly lower than control (P<0.01). Conclusion: The decreased holistic functional capacity of cardiogenic CHF dominantly due to circulatory limitation, and secondly due to respiratory and metabolic limitation.

[Cardiopulmonary exercise testing was used to evaluate objectively and quantitatively the holistic function in patients after neoadjuvant chemotherapy].

Objective: Cardiopulmonary exercise testing(CPET)was used to evaluate objectively and quantitatively the holistic function in patients accepted preoperative chemotherapy. Methods: This study investigated reliable objective and quantitative assessment methods of symptom limited maximal incremental CPET before and after chemotherapy in patients with 6 esophageal cancer. We re-analyzed the changes in cardiopulmonary, metabolism, and other functions physiologic parameters of CPET. Results: After patients accepted preoperative chemotherapy,Peak oxygen consumption (Peak VO2)(P<0.05), anaerobic threshold (AT) and peak oxygen pulse (Peak O2 paulse), oxygen uptake efficiency plateau (OUEP)were decreased (P<0.01). The lowest of ventilatory equivalent for carbon dioxide and slope of ventilatory equivalent for carbon dioxide were increased (P<0.05). For individual of all patients, except one patient's Peak VO2 and OUEP slightly increased,all of the above indicators were reduced in the remaining patients. The lowest of ventilatory equivalent for carbon dioxide and slope of ventilatory equivalent for carbon dioxide increased in all the patients,except one patient's slope of ventilatory equivalent for carbon dioxide decreased slightly. The heart rate of 6 patients showed an upward trend in each state, but there was no statistical difference. Three of the 6 patients had blood pressure measurement, and the other 3 patients had a significant decrease in diastolic blood pressure (P<0.05) except at extreme state.The patients had lower oxygen uptake at AT(P<0. 01) and extreme state (P<0. 05) than that before chemotherapy. The oxygen uptake efficiency in a warm-up state(P<0. 01),and an AT state(P<0. 05)after chemotherapy were lower than those before chemotherapy. The ventilator equivalent for carbon dioxide after chemotherapy was in the each states presented an upward trend, but only ventilator equivalent for carbon dioxide after in the warm-up state (P<0.05) and AT(P<0.01) had statistical significance. oxygen pulse in all four states showed a decreasing trend, and only at AT (P<0.05) showed a significant decrease.After chemotherapy,the PETCO2 in a warm-up state after chemotherapy was lower than that before chemotherapy(P<0. 05); the PETO2 in a quiescent state,a warm - up state,and an extreme state after chemotherapy were higher than those before chemotherapy;but there was nosignificant difference. Conclusion: The holistic functional capacity of patients with esophageal significantly decreased after 136 days chemotherapy. The circulatory functionalandentilator functional parameters significantly decreased after chemotherapy.

[The new theory CPET guides the overall plan of individualized precision exercise to effectively improve the overall functional status of "frailty"].

Objective: Under the guidance of the new theory of holistic integrated physiology and medicine, the effect of individualized accurate exercise program on the overall functional state was studied according to cardiopulmonary exercise testing (CPET). Methods: Li xx, female, 31 years old, has a fast heart rate since childhood (90~100 bpm), usually feel cold, especially in autumn and winter, and general health good. CPET was performed after signing the informed consent form at Fuwai Hospital in September 2019. Peak oxygen uptake, anaerobic threshold (AT), and peak cardiac output were (69~72)% pred, respectively, and the oxygen uptake ventilation efficiency and carbon dioxide exhaust ventilation efficiency were basically normal (96~100)% pred. The resting heart rate was fast, the blood pressure was low, the blood pressure response was weak during exercise, and the heart rate was mainly increased. The holistic integrated physiology medical theory pointed out that she was in weak health and heart weakness was the main manifestation. CPET was used to guide individualized precise exercise intensity titration, combine continuous beat-by-beat blood pressure, ECG, pulse and blood glucose dynamic monitoring to formulate an holisticplan of individualized quantitative exercise .Reexamine CPET after 8 weeks' strengthening management. Results: After 8 weeks of intensive holistic management, the limbs were warm and the cold symptoms disappeared. Re-examination of CPET peak oxygen uptake, AT and peak cardiac output were (90~98)% pred, which increased by (30~36)% respectively, and the holistic weak functional status was significantly improved; basically normal oxygen uptake ventilation efficiency and carbon dioxide exhaust ventilation efficiency also increased by (10~37)% respectively; resting heart rate and blood pressure basically returned to normal, and blood pressure and heart rate response during exercise were normal. Continuous ambulatory blood glucose monitoring indicated that the average blood glucose level decreased slightly and became more stable. Repeated measurement results of continuous ECG and beat-to-beat blood pressure also indicated a decrease in heart rate and an increase in blood pressure during rest, exercise and during sleep, and radial pulse wave. The amplitude of the dicrotic wave increases and becomes more pronounced. Conclusion: The new theoretical system to guide CPET to formulate an holistic plan for individualized precision exercise can safely and effectively enhance myocardial contractility, increase stroke volume, increase blood pressure, lower heart rate, stabilize and slightly lower blood glucose, and improve holistic functional status.

Rehabilitation practice patterns for patients with heart failure: the Asian perspective.

More countries around world have begun to use cardiac rehabilitation in patients diagnosed with chronic heart failure (HF). Asia is the largest continent in the world and, depending on its economy, culture, and beliefs, a given Asian country differs from Western countries as well as others in Asia. The cardiac rehabilitation practice patterns for patients with HF are somewhat different in Asia. In addition to the formal pattern of Western practice, it also includes special techniques and skills, such as Taiji, Qigong, and Yoga. This article describes cardiac rehabilitation patterns for patients with HF in most Asian countries and areas.

[Establishing the idea of holistic integrative medicine, optimizing the quality of health care service in prevention and treatment].

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.

[New theory of holistic integrative physiology and medicine. I: New insight of mechanism of control and regulation of breathing].

OBJECTIVE: The 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. METHODS: We use new theory of holistic integrative physiology and medicine to explain the mechanism of control and regulation of breathing. RESULTS: Except 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. CONCLUSION: Breathing 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.

[New theory of holistic integrative physiology and medicine. II: New insight of the control and regulation of circulation].

OBJECTIVE: The 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. METHODS: Based upon the theory of holistic integrative physiology and medicine, we approach to explain the circulatory control and regulation from its purpose. RESULTS: The 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. CONCLUSION: The circulatory control and regulation is the integration of all systems of the body.

[New theory of holistic integrative physiology and medicine. III: New insight of neurohumoral mechanism and pattern of control and regulation for core axe of respiration, circulation and metabolism].

OBJECTIVE: Systemic mechanism of neurohumoral control and regulation for human is limited. METHODS: We used the new theory of holistic integrative physiology and medicine to approach the mechanism and pattern of neurohumoral control and regulation for life. RESULTS: As 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. CONCLUSION: Based upon integrated regulation of life, we described the neurohumoral pattern to control respiration and circulation.

[Circulatory sleep apnea: Preliminary report of clinical observation on sleep apnea in patients with chronic heart failure].

OBJECTIVE: The aim of this study is to investigate the occurrence and mechanism of Cheyne-Stokes breathing pattern in patients with heart failure. METHODS: Fifty-six patients who performed polusomnography sleep testing at National Center of Cardiovascular Diseases Fuwai Hospital from March to May in 2015. We divided them into chronic heart failure (CHF) group and non-CHF group. RESULTS: The occurrences of sleep apnea in two groups were high. In CHF group (n = 11) , there were 10 patients with apnea hypopnea index (AHI) > 5; and their AHI was 23.93 ±14.63. In non-CHF group (n = 45), there were 33 patients whose AHI > 5; and their AHI was 16.20 ± 18.76. The ratio of center sleep apnea to all gross sleep apnea ratio in CHF group was higher than that in non-CHF group (80.21% ± 30.55% vs 27.16% ± 35.71%, P < 0.01 ). CONCLUSION: Based upon the new theory of holistic integrative physiology and medicine, we explain the mechanism of circulatory dysfunction induce the oscillation breathing in patients with CHF. The sleep apnea and C-S respiration in CHF should be called circulatory sleep apnea, rather than central sleep apnea.

[Human experiments of metabolism, blood alkalization and oxygen effect on control and regulation of breathing. I: room air exercise test].

OBJECTIVE: Under the guidance of the holistic integrative physiology medicine, we reanalyzed the data during symptom-limited maximum cardiopulmonary exercise testing (CPET) in order to investigate control and regulatory mechanism of breathing. METHODS: This study investigated 5 normal volunteers who accepted artery catheter, performed CPET room air. Continuous measured pulmonary ventilation parameters and per minute arterial blood gas (ABG) analysis sample parameters during exercise. All CPET and ABG data changes were standard analyzed and calculated. RESULTS: With gradually increasing power, minute oxygen uptake(every breath oxygen uptake x respiratory rate = O2 paulse x heart rate) and minute ventilation (tidal volume x respiratory rate) showed nearly linear progressive increase during the CPET(compared with the rest stage, P < 0.05 - 0.001); Minute ventilation increased even more significant after the anaerobic threshold (AT) and respiratory compensation point. PaO2 was increased at recovery 2 minutes (P < 0.05); PaCO2 was decreased after anaerobic threshold 2 minutes (P < 0.05); [H+]a was increased from AT (P < 0.05), and rapidly raised at last 2 minutes, remained high at recovery. Lactate was increased rapidly from AT (compared with resting, P < 0.05); bicarbonate decreased rapidly from AT (compared with resting, P < 0.05) and it's changed direction was contrary to lactic acid. CONCLUSION: In order to overcome the resistance of the power during exercise, metabolic rate othe body increased, respiratory change depend upon the change metabolism, and the accumulation of acidic products exacerbated respiratory reactions at high intensity exercise.

[An misunderstanding in traditional interpretation of D(L)CO].

OBJECTIVE: From 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. METHODS: Based 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. RESULTS: The 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. CONCLUSION: The 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.

[Standardizing clinical performance, data analysis, graphics display, interpretation and report for cardiopulmonary exercise testing].

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.

[The new 9 panels display of data from cardiopulmonary exercise test, emphasizing holistic integrative multi-systemic functions].

OBJECTIVE: Since 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. METHODS: The 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. RESULTS: In 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. CONCLUSION: New 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.
