Objective To compare the acceptance of 2 different teaching modes－physicians and therapists teaching together and separately in continuing education students of rehabilitation medicine. Methods A questionnaire was filled by the students who attended the lectures of both Rehabilitation of Elbow Injury and Rehabilitation of Wrist Injury in the 9th National Orthopedic Class. The former lecture was taught by the rehabilitation physician and physical therapist together (together mode), and the latter lecture was taught by the rehabilitation physician and physical therapist separately (separate mode). The questionnaire included the choices and text questions. Results There were 45 copies of effective questionnaire all together. The satisfaction of both lectures were above 90%. As to teaching modes, 77.8% students liked together mode better, and 22.2% students preferd the separate mode. 93.9% students would or maybe use together mode in their future work, and 88.9% in separate mode. Conclusion The mode of physician and therapist giving lectures together is well accepted by students.

OBJECTIVEBasis on the dynamic changes of the ventilation and arterial blood gas parameters to symptom-limited maximum cardiopulmonary exercise testing (CPET), we further investigate the effect of alkalized blood by drinking 5% NaHCO3 on ventilation during exercise.

METHODSAfter drinking 5% NaHCO3 75 ml (3.75 g) every 5 min, total dosage of 0.3 g/Kg, 5 volunteers repeated CPET. All CPET and ABG data changes were analyzed and calculated. At the same time, CPET and ABG parameters after alkalized blood were compared with those before alkalized blood (control) used paired t test.

RESULTSAfter alkalized blood, CPET response patterns of parameters of ventilation, gas exchange and arterial blood gas were very similar (P > 0.05). All minute ventilation, tidal volume, respiratory rate, oxygen uptake and carbon dioxide elimination were gradually increased from resting stage (P < 0.05-0.001), according to the increase of power loading. During CPET after alkalized blood, ABG parameters were compared with those of control: hemoglobin concentrations were lower, CaCO2 and pHa were increased at all stages (P < 0.05). The PaCO2 increased trend was clear, however only significantly at warm-up from 42 to 45 mmHg (P < 0.05). Compared with those of control, only the minute ventilation was decreased from 13 to 11 L/min at resting (P < 0.05).

CONCLUSIONEven with higher mean CaCO2, PaCO2 and pHa, lower Hba and [H+]a, the CPET response patterns of ventilatory parameters after alkalized blood were similar.

OBJECTIVEUnder 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.

METHODSThis 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.

RESULTSWith 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.

CONCLUSIONIn 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.

Objective To investigate the characteristics of carotid atherosclerosis (CA) in patients with acute ischemic cerebrovascular disease (AICD) and explore the relation between metabolic syndrome (MS) and CA. Methods Color Dopple ultrasound was used to examine the carotid artery of 514 patients with AICD and 300 healthy subjects as control group. The intima-media thickness (IMT) of common carotid artery, carotid plaque index, the occurrence rate of CA and the prevalence of MS were compared between the 2 groups. Patients with AICD were divided into CA group and non-CA group according to the occurrence situation of CA; the prevalence of MS and the correlation between MS and single risk factor were analyzed. Results The prevalence of MS, IMT, carotid plaque index and the occurrence rate of CA in the AICD group were all significantly higher than those in the control group (P<0.05). The prevalence of MS, and the incidence of hypertension and high levels of triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), and total cholesterol (TC) in the CA group were significantly increased than those in the non-CA group. After age, gender and smoking adjusted and further adjusted component risk factors of MS, the MS defined by CDS criteria was associated with a 1.81 to 3.96 fold high risk of the CA. The risk of CA in patients with MS accompanied with diabetes was 5.6 times higher than that in patients with MS alone. Conclusion The prevalence of MS and CA in patients with AICD was high. The MS was positively associated with the risk of CA and cooperated with its component risk factors or diabetes to further impact CA.
