Effect of Individualized Cardiac Rehabilitation on Cardiac Function, Time Consumption, and Quality of Life in Patients After CABG.

BACKGROUND: To investigate the effect of individualized cardiac rehabilitation (CR) on cardiac function, time consumption, and quality of life (QoL) in post-CABG patients. METHODS: Two different CR strategy: basic rehabilitation and individualized rehabilitation was designed. The patients were screened and randomized into the two groups: the basic rehabilitation group (BRG) and individualized rehabilitation group (IRG). Data, such as clinical characteristics, LVEF, 6MWD (6-min walk distance), BNP, LVEDD (left ventricular end diastolic dimension), SF-36 score, and time consumption were collected and recorded. RESULTS: There was no difference between the IRG and BRG patients in the clinical characteristics. The 6MWD and LVEF on post-op significantly were higher, while BNP and LVEDD significantly was lower in the IRG than in BRG. The time to first out-of-bed activity, ICU stay time, and post-op hospital stay time of the IRG in post-op was significantly shorter than BRG. The IRG patients scored significantly higher on the SF-36. CONCLUSION: Individualized CR is safe and can reduce the time consumption and improve the cardiac function and QoL of patients undergoing CABG.

Pd(II)-catalyzed, controllable C-H mono-/diarylation of aryl tetrazoles: concise synthesis of Losartan.

A palladium(II)-catalyzed C-H arylation directed by tetrazole, a metabolically stable surrogate for the carboxylic acid group in drug design, has been developed. Excellent mono-/di-selectivity was achieved through adjustment of the protecting site on the tetrazole ring. The synthetic utility of this new transformation was demonstrated in the concise total synthesis of Losartan.

Pd-catalyzed C-H lactonization for expedient synthesis of biaryl lactones and total synthesis of cannabinol.

A practical Pd(II)/Pd(IV)-catalyzed carboxyl-directed C-H activation/C-O cyclization to construct biaryl lactones has been developed. The synthetic utility of this new reaction was demonstrated in an atom-economical and operationally convenient total synthesis of the natural product cannabinol from commercially available starting materials, with the newly developed method used for two key steps.

[Research on the emission spectrum of NO molecule's γ-band system by corona discharge].

The optical emission spectrum of the gamma-band system of NO molecule, A2 sigma+ --> X2 pi(r), has been analyzed and calculated based on the energy structure of NO molecule' doublet states. By employing the theory of diatomic molecular Spectra, some key parameters of equations for the radiative transition intensity were evaluated theoretically, including the potentials of the doublet states of NO molecule's upper and lower energy levels, the electronic transition moments calculated by using r-centroid approximation method, and the Einstein coefficient of different vibrational and rotational levels. The simulated spectrum of the gamma-band system was calculated as a function of different vibrational and rotational temperature. Compared to the theoretical spectroscopy, the measured results were achieved from corona discharge experiments of NO and N2. The vibrational and rotational temperatures were determined approximately by fitting the measured spectral intensities with the calculated ones.
