Grade Ⅲ),preserved LV ejection fraction(EF%≥55%) were involved in present study.TDI and echocardiograms were performed at baseline and during the follow-up period(the time interval between the examinations was 650?362 days).These patients were divided into 2 groups according to the interval LV end-systolic volume(LVESV) with or without 20% increment.Results Corrected by body-surface area,the biplane LVESV,LV end-diastolic volume(LVEDV) and left atrial volume(LAV) increased significantly compared with that of baseline(20?6ml/m2 vs.17?5ml/m2;55?13ml/m2 vs.49?12ml/m2 and 42?11ml/m2 vs.36?14ml/m2,respectively,P

BACKGROUND: The area of myocardial infarction is the determinative factor of acute myocardial infarction prognosis. Amelioration of blood transportation and replacement therapy can reduce infarction area. Bone marrow mesenchymal stem cells can differentiate into cardiovascular tissue and are easy to obtain. After cultured and expanded in vitro, they can become the ideal cells for cardiovascular replacement therapy.OBJECTIVE: To evaluate the therapeutic effect of intracoronary transplantation of bone marrow mesenchymal stem cells in the treatment of myocardial infarction. DESIGN: Self-control observation taking the patients as subjects.SETTING: Department of Cardiology, Department of Nuclear Medicine,Echocardiogram Room, Nanjing First Hospital Affiliated to Nanjing Medical University.PARTICIPANTS: Totally 20 patients with acute myocardial infarction who received the therapy of bone marrow mesenchymal stem cells transplantation in the Department of Cardiology, Nanjing First Hospital Affiliated to Nanjing Medical University during March 2003 to March 2004 were recurited. Informed consents were obtained from the patients, and the complete postoperative follow up was over 3 months. The patients include 15 male and 5 female, and they were aged (64±10) years.METHODS: All the patients underwent percutaneous coronary intervention (PCI) to treat infarction-related blood vessel. Autologous bone marrow was taken from the patients, then stem cells were extracted to be performed in vitro induction, differentiation and proliferation, and transplanted infarction-related blood vessel through coronary artery at the mean number of (21.7±30.14)× 107 within 2 weeks. Before and 3 months after transplantation of stem cells, patients underwent gated dual-isotopic myocardial perfusion/metabolic imaging (18-fluoro-2-deoxy-glucose, 18F-FDG) examination. Survived and necrotic myocardia were predicted and infarction area was obtained. At the same time, wall motion and heart function index were evaluated with ultrasound cardiography (UCG)examination, and they were re-checked 3 months after operation to evaluate the amelioration of wall motion and heart function index. A 5-point scale was used in the evaluation of gated dual-isotopic myocardial perfusion/metabolic imaging (18F-FDG) examination: point 0: normal, 1: sparse, 2:obviously sparse, 3: defected. Evaluative standard of UCG: point 1: normal,2: reduced, 3: obviously reduced, 4: no ventricular wall motion or paradoxical motion; Wall motion with 2 points or more than 2 points suggests it is improved.MAIN OUTCOME MEASURES: ① Results of gated dual-isotopic myocardial perfusion/ metabolic imaging (18F-FDG-SPECT); ②Infarctionrelated myocardial segment score and heart function index before and after stem cell transplantation of patients in ECG follow-up observation.RESULTS: All the 20 patients participated in the result analysis.Results of gated dual-isotopic myocardial perrusion/metabolic imaging (18F-FDG-SPECT): The myocardial perfusion defect area of 20 patients was significantly reduced after therapy than before therapy [(33±15)%,-(44±18)% ,P ＜ 0.05]; Metabolie defect area was significantly reduced after therapy than before therapy [(33±17)%, (43±21)% ,P ＜ 0.05];Before therapy, there were 199 segments, in which blood flow reperfusion was matched to glycometabolism defect, and they were determined as necrotic myocardium. After therapy, blood flow perfusion metabolism was improved in 79 segments, but blood flow perfusion and glycometabolism were not improved significantly in 120 segments (P ＜ 0.05). Results of UCG: ejection fraction of patients was significantly larger after therapy than before therapy [(53±8)%, (42±7)% ,P ＜ 0.05].CONCLUSION: Intracoronary transplantation of human bone marrow mesenchymal stem cells for treating myocardial infarction is simple to operate. After therapy, the infarction area is obviously reduced, myocardial blood flow perfusion and metabolism of necrotic area improve, myocardial segments without survival determined before operation reduce sigrificantly and the heart function of patients improve.

Objective: To explore the relationship between fragmented QRS complex(fQRS) and coronary collateral circulation(CCC) in patients with chronic total occlusion(CTO)lesion without prior myocardial infarction. Methods: This retrospective study analyzed 238 consecutive patients with CTO lesion in one of the major coronary arteries from May 2014 to October 2015 in our department. Patients were divided into poor CCC group (grade 0 and 1, 58 cases) and good CCC group(grade 2 and 3, 180 cases) based on Rentrop′s classification of CCC. The fQRS was defined as the presence of an additional R wave or notching of R or S wave or the presence of fragmentation in two contiguous electrocardiogram leads corresponding to a major coronary artery territory. Multivariate logistic regression was used to analyze the relationship between CCC and fQRS on electrocardiogram. Results: Compared with good CCC group, patients in poor CCC group had older age((65.2±8.9)years old vs. (60.3±10.1) years old, P=0.03), higher plasma glucose ((7.22±3.00) mmol/L vs.(6.31±1.83)mmol/L, P=0.04), and lower left ventricular ejection fraction ((45.2±11.4)% vs. (51.2±13.5)%, P=0.02). None of patients had Rentrop grade 0, the presence of fQRS on ECG in patients with Rentrop grade 1, grade 2, and grade 3 CCC was 69.0% (40/58), 48.6% (35/72) , and 19.4% (21/108), respectively (P<0.01). The presence of fQRS were higher in poor CCC group than in good CCC group (69.0%(40/58)vs. 31.1%(56/180), P<0.01), and number of leads with fQRS were higher in poor CCC group than in good CCC group (3(0, 4)vs.0(0, 3), P<0.01). Multivariate logistic regression analysis demonstrated that poor CCC growth in patients with CTO lesion without prior myocardial infarction was independently related to the presence of fQRS (OR=3.659, 95%CI 1.619-8.217, P<0.01). Conclusion Poor CCC in patients with CTO lesion without prior myocardial infarction is independently related to the presence of fQRS on electrocardiogram.

Objective: To analyze the correlation between circumcision and incidence and clearance of male genital HPV infection. Methods: From May to July 2014, 18-55 year old men who had sexual behavior history were recruited from the general population in Liuzhou, Guangxi to set up a cohort. Totally, 113 circumcised and 560 uncircumcised men were enrolled and interviewed using a questionnaire (including information on demographic characteristics and sexual behaviors), then they were followed-up with 6-month interval for 2 times. On each visit, specimens of male external genitalia were collected and genotyped for HPV DNA. The differences of incidence and clearance of genital HPV infections between circumcised and uncircumcised men were analyzed by Log-rank test. Cox regression was used to analyze the relationship between circumcision and incidence and clearance of HPV infection. Results: The median age (P₂₅, P₇₅) of circumcised and uncircumcised men were 28 (24, 35) and 32 (24, 31), respectively. The incidences of any HPV infections were 9.1 (95%CI: 2.4-15.7) and 8.4 (95% CI: 5.6-11.2) per 1 000 person-months (χ²=0.10, P=0.758), respectively. The clearance of circumcised men [136.3 (95%CI: 70.0-202.7) per 1 000 person-months] was higher than that in uncircumcised men [89.6 (95%CI: 65.9-113.3) per 1 000 person-months] (χ²=8.19, P=0.004). In multivariate COX regression analysis, compared with uncircumcised men, circumcised men had higher possibility to clear any HPV infections (HR: 2.41, 95%CI: 1.30-4.46). Compared with men having one sexual partner, people having more than 4 sexual partners had lower possibility to clear any HPV infections (HR: 0.49, 95%CI: 0.25-0.96). Compared with 18-25 years old men, men aged 26-35 years old had higher possibility to clear high-risk HPV infections (HR: 2.14, 95%CI: 1.08-4.23). Conclusion Circumcised and uncircumcised men had similar incidence of genital HPV infection, whereas, men conducted circumcision and having fewer sexual partners could increase the clearance of genital HPV infections.

OBJECTIVE: To investigate the effectiveness of one-stage total knee arthroplasty (TKA) in the treatment of advanced active knee tuberculosis. METHODS: The clinical data of 38 patients with advanced active knee tuberculosis who received one-stage TKA between January 2011 and December 2020 were retrospectively analyzed. There were 20 males and 18 females. The age ranged from 20 to 84 years, with an average of 52.8 years. The body mass index ranged from 17 to 36 kg/m ², with an average of 23.05 kg/m ². The preoperative C reactive protein (CRP) was (23.49±4.72) mg/L, erythrocyte sedimentation rate (ESR) was (45.95±8.82) mm/1 h. The Hospital for Special Surgery (HSS) score was 48.8±9.1. During the operation, the infected lesions of the knee joint were completely removed, and the operative area was repeatedly soaked with 3% hydrogen peroxide solution and 0.5% povidone iodine solution. The intraoperative pathological examination confirmed the tuberculosis of the knee joint, and systemic anti-tuberculosis treatment was performed. The operation time, postoperative hospitalization stay, postoperative anti-tuberculosis chemotherapy time, and complications were recorded. CRP and ESR were recorded and compared before and after operation. Anteroposterior and lateral X-ray films of the knee joint were taken to evaluate whether the prosthesis had signs of loosening and sinking, and to determine whether there was recurrence of tuberculosis. The knee joint function was evaluated by HSS score. With treatment failure due to any reason as the end event, the survival time of prosthesis was analyzed by Kaplan-Meier survival curve. RESULTS: All operations were successfully completed without fracture, vascular and nerve injury, deep vein thrombosis, and other complications. All incisions healed by first intention after operation. The operation time ranged from 80 to 135 minutes, with an average of 102.76 minutes; postoperative hospitalization stay was 5-16 days, with an average of 9.7 days; the duration of postoperative anti-tuberculosis chemotherapy ranged from 1 to 18 months, and the median duration was 12 months. All 38 cases were followed up 3-133 months (mean, 63.7 months). At last follow-up, CRP was (4.88±1.24) mg/L and ESR was (13.00±2.97) mm/1 h, both of which were significantly lower than those before operation ( t=20.647, P<0.001; t=20.886, P<0.001). During the follow-up, 3 patients (7.89%) had tuberculosis recurrence. Two patients had tuberculosis recurrence due to withdrawal of anti-tuberculosis chemotherapy at 1 and 2 months after operation, respectively. One patient was cured after debridement, preservation of prosthesis and anti-tuberculosis chemotherapy for 12 months, and 1 patient was cured after oral administration of anti-tuberculosis drugs for 12 months. Another 1 patient had recurrent tuberculosis and mixed infection ( Corynebacterium gehreni) at 2 months after operation, and the infection was not controlled after debridement, and finally the thigh was amputated. Except for the patients with recurrent infection, no complications such as prosthesis loosening, periprosthetic fracture, and periprosthetic infection were found. At last follow-up, the HSS score of the knee joint was 86.8±4.8, and the knee joint function significantly improved when compared with that before operation ( t=-31.198, P<0.001). Prosthesis survival time was (122.57±5.77) months [95% CI (111.25, 133.88) months], and the 10-year survival rate was 92.1%. CONCLUSION One-stage TKA combined with postoperative antituberculous chemotherapy in the treatment of advanced active knee tuberculosis can achieve satisfactory infection control and joint function.
