36 mm?Hg. No permanent cardiac pacemaker was implanted. Transit trifascicular was seen in 3 cases, of whom, 2 disappeared with 1 hour after the procedure and, 1 trifascicular disappeared with 3 days. Permanent branch blocks were demonstrated in 36% patients. Conclusion PTSMA was feasible for HOCM with controllable complications. Precise position was the key point to prevent the alcohol leakage which will induce large area myocardial infarction and cardiac shock. Further study was needed to appreciate the more long-term follow-up.

PurposeTo investigate whole-body magnetic resonance imaging in diagnosis of idiopathic inflammatory myopathy (IIM), and to guide clinical treatment.Materials and Methods Twenty-six patients clinically diagnosed IIM including 19 dermatomyositis and 7 polymyositis were analyzed retrospectively. Whole-body MRI was performed in all patients including whole-body coronal scan and axial scan of both sides of thigh. Short tau inversion recovery (STIR) sequences were used in the coronal scan and T1WI and fat-suppressed T2WI were performed in the axial scan. Ten healthy volunteers were recruited as control group. MRI findings were compared between the two groups.Results Whole body MRI showed that muscles were homogeneously low signal intensity in the control group. Imaging findings of the patients with IIM included muscle inflammation, fascitis, subcutaneous tissue edema, muscle atrophy and fatty infiltration. The most common distribution site of muscle inflammation of dermatomyositis patients was thigh (n=18), followed by gluteus (n=14), great psoas muscle (n=13), shoulder muscles (n=11), leg muscle (n=11), erector spinae (n=10) and neck muscles (n=9). Findings out of muscles included cavities in the both lungs, infarction in femurs and tibias, avascular necrosis of femoral head, adrenal mass and thyroid nodules. The most common distribution site of muscle inflammation of polymyositis was thigh (n=5), followed by gluteus (n=3), great psoas muscle (n=3), shoulder muscles (n=2), leg muscles (n=2), erector spinae (n=1) and neck muscles (n=1). Findings out of muscles included 1 case of infarction in femurs and tibias.Conclusion Whole-body MRI can not only comprehensively evaluate the activity of IIM but also detect complications such as bone infarction. It's a powerful tool for diagnosis, guiding treatment and monitoring of IIM.

OBJECTIVE:To observe the effects of butylphthalide combined with alteplase on neural funetion and cognitive function and serological indexes as homocysteine(Hcy)in patients with acute cerebral infarction(ACI).METHODS:Clinical information of 78 ACI patients in emergency department of our hospital during Feb.2140-Apr.2017 were analyzed and then divided into control group and observation group according to therapy plan,with 39 cases in each group. Both groups received conventional treatment and Aspirin enteric-coated tablets orally. Control group was given Alteplase for injection 0.9 mg/kg for verous thromblysis on the basis of conventional treatment. Observation group was additionally given Butyphthalide soft capsules 0.2 g orally,tid,on the basis of control group. Both groups were treated for consecutive 28 days. The clinical efficacies of 2 groups were observed. NIHSS and MMSE scores before treatment,3,7,14 and 28 d after treatment,the levels of Hcy,NSE and 6-k-PGF1a were observed in 2 groups;the occurrence of ADR was recorded. RESULTS:After treatment,total response rate of observation group was 92.31%,which was significantly higher than 71.79% of control group,with statistical significance(P<0.05). 3-28 d after treatment,NIHSS scores of 2 groups were decreased gradually and significantly lower than before treatment;MMSE scores of 2 groups were increased gradually and significantly higher than before treatment,with statistical significance(P<0.05 or P<0.01). 7-28 d after treatment,NIHSS score of observation group was significantly lower than that of control group at same time,while MMSE score was significantly higher than control group, with statistical significance(P<0.05 or P<0.01). After treatment,serum levels of Hcy and NSE in 2 groups were decreased significantly,and observation group was significantly lower than control group;the level of 6-k-PGF1a was increased significantly,and observation group was significantly higher than control group,with statistical significance(P<0.05 or P<0.01). There was no statistical significantce in the total incidence of ADR between 2 groups(P>0.05). CONCLUSIONS:Butylphthalide combined with alteplase can significantly improve neurologic impairment and cognitive function of ACI patients,reduce serum levels of Hcy and NSE and increase the level of 6-k-PGF1a. Clinical efficacy of it is significantly better than alteplase alone.

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.

A fluorescent microsphere-based immunochromatographic strip test (FICT) was developed for the rapid, sensitive, and quantitative detection of porcine reproductive and respiratory syndrome virus (PRRSV) antibodies at the pen-side. The assay was based on the formation of a sandwich immune-complex (anti-pig IgG-PRRSV antibodies-NSP7/N), which was validated by a comparison with IDEXX-ELISA using 3325 clinical specimens. The diagnostic specificity, sensitivity, and accuracy of FICT were 97.28, 93.41, and 94.95%, respectively. FICT showed a good correlation with the virus neutralization assay. Overall, a promising pen-side diagnostic tool was developed for the rapid and quantitative detection of PRRSV antibodies within 15 min.
