Abstract
Objective To evaluate the safety and efficacy of autologous bone marrow mesenchymal stem cells transplantation for angina.Methods Forty patients with angina were divided into treatment group(n=20) and control group(n=20).The treatment group received autologous bone marrow mesenchymal stem cells transplantation following regular medicine therapy and percutaneous coronary intervention.Control group only received regular medicine therapy and percutaneous coronary intervention.Two dimensional echocardiography,single-photon emission computed tomography imaging and ECG Holter monitor were done before and 6 months after the procedure.The complications as acute myocardial infarction and arrhythmia were observed and the efficacy for angina was evaluated intraoperatively,3 and 6 months after the procedure.Results The angina frequency,nitroglycerine usage,exercise time and Canadian Cardiovascular Society class in the treatment group were superior to those in control group(P0.01).Single-photon emission computed tomography showed the perfusion defect in treatment group was smaller than that in control group.No myocardial infarction or arrhythmia occurred during the transplantation in both two groups.There were no serious adverse events in the two groups during and after the procedure.Conclusion Intracoronary transplantation of autologous bone marrow mesenchymal stem cells is safe and effective for angina.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
