Chinese Journal of Tissue Engineering Research 2012;16(1):99-102
BACKGROUND: Transplantation of the human umbilical cord blood mononuclear cells (HUCBCs) have received increasing attention, as a promising candidate for the cellular transplantation, but the majority of the existing studies are basic research.OBJECTIVE: To report a patient of extensive anterior-wall acute myocardial infarction with cardiogenic shock and severe heart failure, after treatment of HUCBCs transplantation. METHODS: A 73-year-old female patient with cardiogenic shock and severe heart failure after extensive anterior-wall acute myocardial infarction was treated with percutaneous coronary intervention (three scaffolds implantation) and medications, and she still appeared the symptoms of congestive heart failure, such as severe recurrent dyspnea. 2.4 × 108 HUCBCs (50 mL cell suspension) was injected into the infarcted myocardium through the left anterior descending artery by using coronary micro-guide catheter.RESULTS AND CONCLUSION: The patient reported profound clinical benefit including improvement of heart-failure-associated symptoms after the transplantation. Notably the patient did not experience the cell transplant-related side effects during 4 months of follow-up. The ejection fraction increased from 22% before the transplantation to 53% at 21 days after the transplantation. The B-type natriuretic peptide decreased from 1 730 ng/L before the transplantation, 854 ng/L after the transplantation to 264 ng/L at 21 days after the transplantation. The patient did not appear the symptoms of congestive heart failure, including dyspnea, chest distress and hypodynamia, she returned to daily activity at 4 months of follow-ups. Experimental findings indicate that the HUCBCs transplantation is an effective and safe means for patients cardiogenic shock and severe heart failure after acute myocardial infarction.

3.Intracoronary transplantation of autologous peripheral blood stem cells in old patients with acute myocardial infarction:5-year postoperative evaluation of cardiac function
Chinese Journal of Tissue Engineering Research 2014;(1):125-130
BACKGROUND:Myocardial infarction patients commonly appear to have left ventricular remodeling and heart failure. Because of physical characteristics, these two complications are more likely to occur in elderly patients with myocardial infarction. In recent years, stem celltransplantation in the treatment of acute myocardial infarction and heart failure has become a hot topic, and the feasibility and safety has been confirmed, but its long-term outcomes in elderly patients are stil unclear.
OBJECTIVE:To assess the long-term effect of transplantation of autologous peripheral blood stem cells on the left ventricular remodeling and heart function in the old patients with myocardial infarction.
METHODS:Thirty old patients (age ≥ 60 years) with myocardial infarction were randomly assigned to receive intracoronary transplantation of peripheral blood stem cells fol owing bone marrow cells mobilization by granulocyte colony-stimulating factor ( 300-600μg per day) subcutaneously for 5 days in addition to conventional therapy (standard drug therapy and percutaneous coronary intervention;transplantation group, n=15) or standard therapy (standard drug therapy and percutaneous coronary intervention;control group, n=15) . Complications during intervention, left ventricular function and left ventricular remodeling at baseline and 6, 12, 24, 60 months after treatment were monitored.
RESULTS AND CONCLUSION:Left ventricular function, left ventricular end diastolic volume, and left ventricular end-systolic volume were significantly improved 6,12, 24, 60 months after autologous peripheral blood stem celltransplantation compared to baseline, while these parameters remained unchanged in the control group. These parameters had statistical difference between the two groups after treatment. During the fol ow-up, no severe side effects were observed. These findings indicate that autologous peripheral blood stem celltransplantation leads to significant and longstanding improvements in left ventricular performance of old patients with myocardial infarction, and shows good safety.
4.Umbilical cord blood mononuclear cell transplantation is safe for treatment of coronary heart disease with heart failure
Chinese Journal of Tissue Engineering Research 2013;(49):8557-8562
BACKGROUND:Number of experimental and clinical studies have shown that stem celltransplantation can establish new blood vessels and improve heart function instead of necrotic myocardium, to significantly improved clinical symptoms and prognosis of cardiovascular disease patients.
OBJECTIVE:To observe the safety of human umbilical cord blood mononuclear cells transplantation in patients with coronary heart disease and heart failure.
METHODS:A total of 12 patients with coronary heart disease and heart failure (acute myocardial infarction and heart failure in six cases, old myocardial infarction and heart failure in six cases) were enrol ed in this study. Patients were treated on the basis of standard medication and percutaneous coronary intervention. The coronary pathway was established via a percutaneous catheter, and suspension of cord blood mononuclear cells was injected through microcatheter into the distal artery. Routine blood test was carried out at 1 week after celltransplantation, blood routine, liver function, kidney function, C-reactive protein, IgA, IgG were compared preoperatively and postoperatively.
RESULTS AND CONCLUSION:The incidence of adverse reactions in cord blood stem celltransplantation was 8.3%, including one case of fever. No micro-embolism occurred. During 1-week fol ow-up, no graft-versus-host disease appeared. After celltransplantation, there were no significant changes in blood routine, liver function, kidney function, C-reactive protein, IgA, IgG. These findings indicate umbilical cord blood monomuclear cells transplantation is safe in a short term for patients with coronary heart disease and heart failure.

Objective To systematically evaluate the safety of high dose atorvastatin (80 mg daily) in Chinese patients. Methods Randomized controlled trials (RCTs) investigating 80 mg/ d atorvastatin vs. low-dose atorvastatin or placebo or blank were electionically retrieved in date bases of EMbase, PubMed, the Cochrane Library, WanFang, CNKI and WeiPu. Meta-analysis was performed using RevMan 5. 2 and Stata 11. 0 software. Results A total of 20 RCTs involving 2282 cases were included. The results of meta-analysis showed no significant differences betweent the 80 mg/ d atorvastatin group and the control group in the incidence of gastrointestinal adverse events (RR 1. 53, 95% CI 0. 85-2. 76, P = 0. 16), hepatic adverse events (RR 1. 53, 95% CI 0. 99 - 2. 36, P = 0. 05), muscular adverse events (RR 1. 51, 95% CI 0. 92 -2. 49, P = 0. 10), serious hepatic injuries ( RR 2. 33,95% CI 0. 88 - 6. 20, P = 0. 09) and serious muscular myopathies (RR 1. 40, 95% CI 0. 46 - 4. 30, P = 0. 56). Subgroup analysis by type of cotrast media used and durations of taking 80 mg/ d atorvastatin showed there were higher risks of gastrointestinal adverse events in the 80 mg/ d group when compared to blank control ( RR 4. 22, 95% CI 1. 11 - 16. 04, P = 0. 03). Conclusions The current evidence shows that 80 mg / d atorvastatin may be relatively safe in terms of adverse events in gastrointestinal tract, liver and muscular system, and relatively has risk in causing severe liver injuries and myopathies. With limited quantity and quality from the RCTs available, more high quality RCTs are needed to verify the above conclusion.

BACKGROUND:The hidden blood loss, accounted for a fairly large proportion of perioperative blood loss in total hip replacement, can seriously affect the recovery of postoperative joint function, but the specific influential factors and mechanisms remain unknown at present. OBJECTIVE:To evaluate the relative influential factors for hidden blood loss after primary total hip arthroplasty by the blood loss condition, and to analyze the association between hidden blood loss and prognosis. METHODS:Clinical data of 110 patients who underwent primary total hip arthroplasty in the Liuzhou Worker’s Hospital between April 2011 and April 2013 were retrospectively analyzed. The hidden blood loss was calculated according to Ward and Gross formula. The effects of patient’s gender, age, body mass index, type of prosthesis, presence of internal diseases, and different causes of a disease on hidden blood loss after arthroplasty were analyzed. The patients were divided into the high blood loss group (≥ 480 mL) and the low blood loss group (<480 mL) according to the hidden blood loss. Al the patients were fol owed up for 1 year. The Harris hip score system was used to assess the recovery of hip joint function between the two groups. The correlation between hidden blood loss and the recovery of joint function was analyzed using Pearson’s correlation analysis RESULTS AND CONCLUSION:The total blood loss of primary total hip arthroplasty was (1 340±367) mL, and the hidden blood loss was (748±324) mL, and the percentage of hidden blood loss was 53.7%. The type of prosthesis, presence of internal diseases, and different causes of a disease were significantly associated with hidden blood loss after total hip arthroplasty (P<0.05). Gender, age, body mass index, and operation time were not significantly associated with hidden blood loss after total hip arthroplasty (P>0.05). The hidden blood loss was correlated with postoperative functional recovery (P=0.046). Results indicated that type of prosthesis, presence of internal diseases, and different causes of a disease are main influential factors for hidden blood loss after total hip arthroplasty. The hidden blood loss has some influence on the recovery of postoperative joint function.

Objective Radionuclide-labeled low molecular weight polypeptide is reeently advocated for the diagnosis and treatment of malignant tumor. The purpose of this study was to evaluate the anti-tumor effect of 131Ⅰ-Tyr-octreotide in nude mice bearing human non-small cell lung cancer (NSCLC). Methods 131Ⅰ-Tyr-octreotide was prepared by Ch-T method. The radiochemical purity was measured and biodistribution was evaluated. The nude mice models bearing human NSCLC were studied and divided into four groups: group A injected 131Ⅰ-Tyr-octreotide through tail vein, group B injected normal saline, group C injected 131Ⅰ-Tyroctreotide through stroma and group D injected 131Ⅰ through stroma. The radioactivity ratio of tumor to normal tissue (T/NT) was calculated over region of interest (ROI). The tumor cell cycle and cell apoptosis were analyzed by flow cytometry (FCM), terminal deoxynucleotidyl transferase mediated dUTP-biotion nick end labeling (TUNEL) and histopathological analysis. Statistical analysis was performed with SPSS 11.0, and the comparison for difference between groups performed with one-way ANOVA analysis. Results The labeled radiochemical purity was (95.23±1.67)% and specific activity of 3.5×106Bq/ug. The biodistributiou showed high uptake in kidney, and low uptake in liver and spleen. The radioactive uptake in group C was higher than the other groups, and the retention time was longer. The T/NT was 52.74±0.13 after 24 h, which was much higher than that the other groups (group D: 8.90±0.23, group A: 6.42±0.02, q=628.81 and 664.33, all P<0.05). The resuits of tmnor cell cycle determined by FCM showed that the G1 phase was blocked mast remarkably in group C than the other groups [group C: (83.17±6.86)%, group A: (57.02±18.81)%, group D: (49.29±7.80)%, group B: (45.88±5.13)%, q=5.29, 6.86, 7.55, 1.56, 2.26, 0.69, all P<0.05]. Apeptotic cells were observed by TUNEL, and apoptotic body was detected by immuno-histochemical examination. Conclusions 131Ⅰ-Tyr-octreotide was easily labeled by Ch-T. 131Ⅰ-Tyr-octreotide could induce tumor cell apoptosis and inhibit the tumor cell of NSCLC. It might be a potential target-directed agent in NSCLC.
