Objective To quantify the effect of rehabilitation training on cardiopulmonary function and the quality of life of patients with coronary heart disease after percutaneous coronary intervention (PCI). Methods Sixty-nine patients after PCI were randomly divided into three groups. Those in group A were given conventional medical therapy; group B had additional walking exercise; group C had both additional respiratory training and the additional walking exercise. Treadmill exercise tests, pulmonary function examinations and a health questionnaire were used to evaluate cardiopulmonary function and quality of life after three months of treatment. Results After three months of treatment cardiopulmonary function and quality of life had improved significantly in groups B and C, and there was significant difference between groups B and C. Conclusion Walking and respiratory function training can improve cardiopulmonary function and quality in life after PCI.

Objective To evaluate the role of phosphatidylinositol 3-kinase (PI3K)/protein-serinethreonine kinases (Akt) signaling pathway in dexmedetomidine postconditioning-induced reduction of myocardial ischemia-reperfusion (I/R) injury in rats.Methods Seventy-two healthy male Sprague-Dawley rats,aged 4-5 months,weighing 200-240 g,were heparinized and anesthetized with intraperitoneal pentobarbital sodium 40 mg/kg.Their hearts were rapidly excised and perfused in a Langendorff apparatus with oxygenated (95％ O2-5％ CO2) K-H solution at 0-4℃.The isolated hearts were randomly divided into 6 groups (n =12 each):control group (group C),group I/R,dexmedetomidine postconditioning group (gruop D),solvent group (group DMSO),PI3K inhibitor LY294002 group (group L) and LY294002 + dexmedetomidine postconditioning group (group L + D).After a 20 min stabilization period,the hearts were continuously perfused with K-H solution for 120 min in group C and were subjected to 30 min of global no-flow ischemia followed by 90 min of repeffusion in the other groups.Dexmedetomidine 100 nmo/L was added during the initial 30 min of reperfusion in D and L + D groups.LY294002 15 μmol/L was added in L group.0.02％ DMSO containing 15 μmol/L LY294002 was added in L + D group.0.02％ DMSO was added in DMSO group.HR,left ventricular end-diastolic pressure,left ventricular developed pressure and ± dp/dtmax were recorded at the end of 20 min stabilization and 15,30 and 90 min of reperfusion.The expression of phosphorylated Akt (p-Akt) and Akt was measured at 30 min of reperfusion.Myoeardial infarct size was determined using TTC staining at 90 min of reperfusion.Results Compared with group C,HR,left ventricular developed pressure and ± dp/dtmax were significantly decreased,and left ventricular enddiastolic pressure and myocardial infarct size were increased in the other 5 groups,and the expression of p-Akt was significantly up-regulated in group D (P ＜ 0.05).Compared with group I/R,HR was significantly decreased at 15 and 30 min of reperfusion,the expression of p-Akt was up-regulated,and myocardial infarct size was decreased in group D (P ＜ 0.05).Compared with group D,the expression of p-Akt was down-regulated,and myocardial infarct size and HR was increased in L + D group (P ＜ 0.05).Conclusion Dexmedetomidine postconditioning attenuates myocardial I/R injury throuth activating PI3K/Akt signaling pathway in rats.

Patent ductus arteriosus (PDA)is a common disease among premature neonates and the management of which has always been a challenge to the neonatologists. Early treatment has been advocated as the first-line approach, and drug induced closure is yet the most effective, inexpensive, and convenient method. During the last two decades,indomethacin was often given as conservative treatment, and its closure rate in PDA was approximately 46% ～ 89%. However,indomethacin may increase the number of undesirable or harmful effects including renal damage, intraventricular hemorrhage, necrotizing enterocolitis, and enterobrosis,etc. Recently,ibuprofen is rapidly emerging as a new promising drug for treatment of PDA in preterm infants with closure rate of 73.0% ～95.5%. It is used as standard therapy to close PDA,and it has less influence on the hemodynamics of kidneys, brain and gastrointestinal tract. The surgery is needed in patients with drug treatment failure and cardio-pulmonary function damage.

Objective To explore the effect of progressive active respiratory exercise on the pulmonary function and quality of life of middle-aged and elderly patients after surgery for carcinoma of the esophagus.Methods Forty post-operative middle-aged and elderly patients with carcinoma of esophagus were randomized into 2 groups.The patients in the control group were given conventional thoracic nursing,while those in the experimental group were given 3-step thoracic or abdominal breathing training,breath holding training and respiratory gymnastics training in addition.A lung function test,the 6-min walk test and a 36-item short form health survey (SF-36)were used to evaluate the subjects' pulmonary function,motor ability and quality of life after 3,6 and 12 months of treatment.Results Vital capacity (VC) increased 23％ after training.Forced vital capacity (FVC) increased 16％.Maximal ventilation volume (MVV) increased 15％ and 50％ of forced expiratory flow (FEFS0) and the diffusing capacity for carbon monoxide of the lungs (DLCO) increased 30％.Average distance in the 6-minute walk test (6MWD) lengthened from 320 m to 449 m,and the quality of life of the patients in the experimental group improved much more than that of the control group.The average pulmonary function and 6MWD of the control group did not improve significantly with only nursing care.Their average SF-36 scores for physical function,mental health,physical pain,mental role and comprehensive health did,however,improve significantly after treatment.The changes in their role limitation,social function and energy scores were not significant.Conclusion Early and progressive active respiratory exercise can ameliorate lung dysfunction after a thoracic operation,and improve motor ability and quality of life.
