Journal of Peking University(Health Sciences) 2003;0(04):-
SUMMARY A 61-year-old male patient, with the history of premier myocardial infarction and CABG surgery, experienced recurrent unstable angina. Angiography showed triple vessel disease and vein grafts obstruction. The patient underwent a re-do OPCAB + TMLR + bone marrow mononuclear cell (BM-MNCs) transplantation on Nov. 8, 2004. BM-MNCs were isolated with standard gravity gradient method and the final implanted cell number was 12.06?108. Peri-operative data were similar to those of single OPCAB or re-CABG. The patient recovered promptly without recurrence of angina or infarction. Six-minute walking distance increased significantly (366 m to 493 m). Several imaging examinations reveal improved left cardiac function (LVEF improved from 23.75% to 52% in MRI) and diminished MI area. The results reveal that bone marrow cell transplantation, combined with TMLR and OPCAB is safe and might be effective in improving heart function for patients with IHD.

Objectives To establish a model of carotid atherosclerotic (AS)stenosis in rabbits and to preliminarily investigate the expression of asparaginyl endopeptidase. Methods Fourteen New Zealand white rabbits were divided into either an model group (n = 8)or a sham operation group (n = 6)according to the random number table. The carotid intima was injured by operation in the model group. The rabbits in both groups were fed with high fat diets containing magnesium for 10 weeks. The rabbits were weighted and their blood lipids were tested every 2 weeks. At the end of the fifth and tenth weeks after procedure,the plaque and vessel stenosis of the rabbits were observed by MRI. At the end of the tenth week after proce-dure,the specimens were collected and sliced. Hematoxylin and eosin (HE)staining was used to observe the pathological changes. Immunohistochemical staining was used to analyze the expression of asparaginyl endopeptidase (AEP). Results One rabbit in the model group died of carotid artery injury. After being fed with high-fat diets,the body quality and the level of blood lipid were increased in the rabbits of both groups compared with those before procedure (all P < 0. 01). At the end of the fifth and tenth weeks after procedure,MRI revealed that the luminal stenosis rates in the operation group were 16 ± 11% and 53 ± 20% respectively. There was significant difference within the group (t = - 4. 83,P < 0. 01). MRI revealed no luminal stenosis twice in the sham operation group. HE staining showed intimal hyperplasia,AS plaque formation,lipid deposition in plaques,macrophage and smooth muscle cells migration and infiltration forming foam cells in the model group. No AS formation was observed in the sham operation group. The expression of AEP was higher in the rabbit carotid artery tissue in the model group,and it expressed rarely in the sham surgery group. The absorbance values were 0. 072 0 ± 0. 028 0 and 0. 002 0 ± 0. 000 9 respectively. There was significant difference (t = 6. 61,P < 0. 01). Conclusions The methods of injuring carotid intima combined with magnesium containing high-fat diet may exactly,reliably,and quickly establish an AS carotid artery stenosis model. AEP may associat with the occurrence of AS plaques.

The DNA fragment sized 2 139bp, the same Sequence with AtKup1 gene from Arabidopsis thalianna was used as the templates for DNA family shuffling. The shuffeld AtKup1 gene library was expressed in the mutant of 5. cerevisae in which potassium transporter gene TRK1 and TRK2 were knocked out by homologous recombination. Then the screening was carried out in the low potassium media containing 5. 0 mmol/L KC1 and no histidine in it. it was found that both of diverse and wild AtKup1 gene can rescues the trk1△trk2△yeast mutant strain in low [ K + ] medium. The growth of 2 clones yeast containing diverse AtKup1 were beter than that of AtKup1 wild gene transformant. The sequencig results of the shuffeld AtKup1 showed that there were 2 nucleotide changed, which resulted in 2 amino acid variations in it compared with the original AtKup1. The potassium uptaking capacity of shuffled AtKup1 gene increased significantly when it was transformed into tobacco.

Objective To investigate the clinical value of low-dose decitabine (DAC) in elderly patients with acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS) patients with intermediate-or high-risk. Methods Low-dose DAC (10 mg/d, 7 days) combined with CAG regimen were given to 19 elderly patients with AML and intermediate- or high-risk MDS patients. The efficacy and adverse reactions were evaluated after a course of treatment, and the patients were followed up for survival. Results After a course of treatment, 8 patients achieved complete remission (CR), 7 patients achieved partial remission (PR). After 4 courses of treatment, 68.4 % (13/19) of patients achieved CR, the overall response rate reached 78.9% (15/19). Fewer side effects were seen associated with chemotherapy. After 42 months of follow-up, there were 12 survival cases, the median survival time was 13.5 months (3-42 months). Conclusion Low-dose DAC combined with CAG regimen have a better efficacy, higher safety, and lower economic burden for elderly AML patients and intermediate- or high-risk MDS patients, which is beneficial to greatly improve patients' compliance.
