Input: Consider Input: Context: Almost all the past CSWT studies show the beneficial effects on CAD patients in a maximum duration of 1-year follow-up. The aim of this study was to evaluate the actual CSWT effects in 6 years follow-up period.', 'The subjects were selected exclusively on the basis of inclusion criteria. The total number of patients was 52, out of which control group (n = 11) and the shock wave group (SW group, n = 41) was selected.', 'The wall motion, MPI, nitrate dosage, NYHA classification, SAQ scores, CCS grading, 6 MWT were markedly improved in the long-term (6 years) follow-up for SW group than the control group.
Answer: Following 6 years of follow-up, the CSWT provided agreeable results that improved myocardial function and quality of life in comparing to the month 0 and the control group. These outcomes advise that on a long-term (72 months) CSWT shows better parameters than the control group. These findings highlight that CSWT can improve clinical symptoms, morphology, functions of the heart and quality of life in patients with CHD than the patients just on drug therapy for a long-term.

Output: Does cardiac shock wave therapy show better outcomes in the coronary artery disease patients in a long term?


Input: Consider Input: Context: The proportion of dendritic cell subpopulations in the skin is important for the severity of atopic dermatitis because topical treatment with tacrolimus leads to rapid depletion of inflammatory dendritic epidermal cells, whereas Langerhans cells (LCs) predominate in cured sites.', 'The effects of tacrolimus and TGF-beta1 on LC differentiation and the idea of tacrolimus skewing the differentiation of epidermal precursors to LCs were evaluated.', 'The presence of LC markers, MHC, and costimulatory molecules and stimulatory capacity toward T cells of monocyte-derived LCs were analyzed. Skin samples of patients with atopic dermatitis were assessed by means of immunofluorescence microscopy before and after tacrolimus treatment. TGF-beta production of skin cells was analyzed.', 'Tacrolimus and TGF-beta1 act synergistically on the generation of LCs and the expression of CD40, CD80, CD86, CD83, and MHC II; stabilize TGF-beta receptor II expression; and decrease the stimulatory capacity of LCs toward T cells. In vivo the number of epidermal LCs in tacrolimus-treated skin increased.
Answer: The synergism between TGF-beta1 and tacrolimus leads to the generation of LCs, reduced expression of costimulatory and MHC II molecules, and reduced stimulatory activity. Shifting the balance of the dendritic cell population to LCs might be of major importance for the therapeutic effect of tacrolimus.

Output: Do tacrolimus and TGF-beta act synergistically on the generation of Langerhans cells?


Input: Consider Input: Context: During cardiopulmonary resuscitation (CPR), myocardial blood flow generated by chest compression rarely exceeds 35% of its normal level. Cardiac output generated by chest compression decreases gradually with the prolongation of cardiac arrest and resuscitation. Early studies have demonstrated that myocardial blood flow during CPR is largely dependent on peripheral vascular resistance. In this study, we investigated the effects of chest compression in combination with physical control of peripheral vascular resistance assisted by tourniquets on myocardial blood flow during CPR.', 'Ventricular fibrillation was induced and untreated for 7 min in ten male domestic pigs weighing between 33 and 37 kg. The animals were then randomized to receive CPR alone or a tourniquet assisted CPR (T-CPR). In the CPR alone group, chest compression was performed by a miniaturized mechanical chest compressor. In the T-CPR group, coincident with the start of resuscitation, the thin elastic tourniquets were wrapped around the four limbs from the distal end to the proximal part. After 2 min of CPR, epinephrine (20 μg/kg) was administered via the femoral vein. After 5 min of CPR, defibrillation was attempted by a single 150 J shock. If resuscitation was not successful, CPR was resumed for 2 min before the next defibrillation. The protocol was continued until successful resuscitation or for a total of 15 min. Five minutes after resuscitation, the elastic tourniquets were removed. The resuscitated animals were observed for 2h.', 'T-CPR generated significantly greater coronary perfusion pressure, end-tidal carbon dioxide and carotid blood flow. There was no difference in both intrathoracic positive and negative pressures between the two groups. All animals were successfully resuscitated with a single shock in both groups. There were no significant changes in hemodynamics observed in the animals treated in the T-CPR group before-and-after the release of tourniquets at post-resuscitation 5 min.
Answer: T-CPR improves myocardial and cerebral perfusion during CPR. It may provide a new and convenient method for augmenting myocardial and cerebral blood flow during CPR.


Output: Does a tourniquet assisted cardiopulmonary resuscitation augment myocardial perfusion in a porcine model of cardiac arrest?
