OBJECTIVETo investigate the impairment pattern and the influencing factors of pulmonary function in patients with Marfan and Marfanoid syndrome associated scoliosis (MS).

METHODSIn this retrospective study, totally 25 MS patients (aged 11 - 20 years, 11 boys and 14 girls) who received posterior instrumentation and fusion (Group A) and 38 adolescent idiopathic scoliosis (AIS) patients (Group B) (aged 10 - 19 years, 11 boys and 27 girls) were included from February 1998 to September 2007. The curve pattern was matched in both groups. The preoperative pulmonary function test (PFTs) were compared in two groups. And the parameters influencing the preoperative pulmonary function were analyzed in group A.

RESULTSIn Group A, the Cobb angle of thoracic curve was negatively correlated with the percentage of predicted pulmonary volumes (VC%, FVC% and FEV1%) (r = -0.514, -0.503, -0.464, P < 0.05). And the reduction of lung function parameters (VC%, FVC%, FEV1% and MMEF%) was more severe in Group A than in Group B with compared magnitude of thoracic curve (P < 0.05). In Group A, the extent of impairment of pulmonary function in patients with the number of vertebrae involved ≥ 8 were more severe than those involved < 8 vertebrae (P < 0.05). However, there was no significant difference of deterioration of lung function between the higher apex (T₄₋₈) subgroup and lower apex (T₉₋₁₂) subgroup. And no correlation was found between thoracic kyphosis and the degrees of impairment of respiration function.

CONCLUSIONSPatients with MS have mixed ventilation dysfunction, which is more severe than AIS patients with matched age and Cobb angle. The pulmonary dysfunction in MS patients can be influenced by the severity of thoracic curve and the number of involved vertebrae.

BACKGROUNDInvasive intravascular ultrasound (IVUS) is current diagnostic standard for myocardial bridging (MB). Non-invasive multislice computerized tomography coronary angiography (MSCT) technique has provided a good anatomical view of the tunnel artery now.

METHODSA total of 51 consecutive patients with atypical or typical angina scheduled for IVUS were enrolled in this study and MSCT was performed 7 days before IVUS. Coronary imaging was quantified using IVUS and MSCT. Four main vessels (left main artery (LMA), left anterior descending (LAD), left circumflex (LCX), right coronary artery (RCA)) were examined.

RESULTSForty-one out of 51 (80%) patients received metaprolol (25 mg) before the MSCT scan and 25 of them were current beta-blocker users. The mean heart rate was (64 +/- 3) beats per minute. A total of 51 patients underwent IVUS examination (30 with MB and 21 without MB) were chosen for this study. Twenty-eight out of 30 MB cases were correctly diagnosed by MSCT and 2 patients with MB were not detected. Comparison with IVUS, the sensitivity of detection by MSCT was 93%, specificity was 100%. The lumen diameter of the tunnel artery derived from MSCT and IVUS significantly decreased from (2.9 +/- 0.3) mm to (2.4 +/- 0.4) mm (P < 0.001) and from (3.3 +/- 0.3) mm to (2.6 +/- 0.5) mm (P < 0.001), respectively. Minimal and maximal diameters of MB derived from MSCT were significantly smaller than those from IVUS ((2.4 +/- 0.4) mm vs (2.6 +/- 0.5) mm, P < 0.05 and (2.9 +/- 0.3) mm vs (3.3 +/- 0.3) mm, P < 0.05), respectively.

CONCLUSIONSMSCT offers a reliable non-invasive method for MB in LAD and atherosclerosis diagnosis with diagnostic accuracy comparable with invasive IVUS.

OBJECTIVETo investigate the safety of autologous bone marrow mononuclear cell (BM-MNCs) transplantation by intracoronary infusion in patients with acute myocardial infarction (AMI).

METHODSOne hundred and eighty-four patients with AMI treated with percutaneous coronary intervention (PCI) were randomized in a 1:1 way to either intracoronary transplantation of autologous BM-MNCs (n = 92) right after PCI or to sodium chloride concluding heparin (controlled, n = 92) via a micro infusion catheter. In the process of the intracoronary infusion of BM-MNCs, the complications should be recorded, which were aberration reflect (including of pale, syncope, nausea, hypotension and shock), deterioration of angina or heart failure, arrhythmias (including of bradycardia, sinus arrest or atrial ventricular block or ventricular fibrillation), embolism etc. Body temperature, blood pressure and heart rates should be monitored during the first week after transplantation. Holter, coronary angiography and ultrasonic cardiography were performed at the designed time points. Main heart accidents, restenosis and tumor were recorded during 2-years follow up.

RESULTSDuring the period of bone marrow puncture and intracoronary infusion of BM-MNCs, few patients occurred pale, dizziness, bradycardia and hypotension, which were transient and due to vagus reflect. No stem cell-related arrhythmias, deterioration of angina were noted. In BM-MNCs group one patient developed in-stent reocclusion in one week after transplantation, five developed in-stent restenosis during further follow-up 30 months, which were similar with control group. There were no deaths, major adverse cardiac events, tumor and other late adverse events during follow-up period in both groups.

CONCLUSIONIntracoronary transplantation of autologous BM-MNCs in the acute phase after AMI is feasible and seems safe in the 30 months of follow-up.

The study was aimed to evaluate the impact of disease status on the outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) in patients with refractory and relapsed acute myeloid leukemia (AML). 32 patients with refractory and relapsed AML received allo-HSCT after myeloablative conditioning regimen, including 17 patients in no-remission (NR) and 15 patients in complete remission (CR) at the time of transplant. Treatment related adverse events, relapse rate and leukemia free survival (LFS) were analyzed. The results showed that the parameters of sex, age, cytogenetic risk and transplant procedures were comparable between the two groups. 30 patients had successful engraftment, except one had graft failure and one died from severe veno-occlusive disease in the NR group. The incidences of aGVHD in NR group and CR group were 47.1% (8 patients) and 33.5% (5 patients) respectively. Out of comparable patients, 5 from 9 patients in NR group developed with cGVHD, and 4 from 11 patients in CR group were subjected to cGVHD. There were no statistic difference in incidences of aGVHD and cGVHD between two group. Compa-red with CR group, NR group had a higher treatment-related mortality (29.4% vs 14.3%, P = 0.392) and relapse rate (42.9% vs 26.7% P = 0.300), but there was no significant difference. With a median follow-up of 13 (1 - 124) months, 6 patients remained alive in both of the two groups, and the 2 year LFS of them were parallel (35.3% vs 40.0%, P = 0.267). Among these 32 patients, overall survival (OS) was better in patients with age < 35 years (P = 0.044) and with the appearance of cGVHD (P = 0.046). It is concluded that allo-HSCT is an effective salvage therapy for patients with refractory and relapsed AML, and the overall outcome seems unrelated to the disease status (NR or CR) before transplantation. As such, for refractory and relapsed AML patients in non-remission, performance of allo-HSCT to achieve long-term survival is feasible.

The historical evolution， fermentation technology and key links of Sojae Semen Praeparatum （SSP） were sorted out by consulting ancient books and modern literature， and the influencing factors and control methods of quality were analyzed and summarized in order to provide reference for the quality control of SSP. After analysis， it was found that in the fermentation process of SSP， fermentation strains， miscellaneous bacteria， temperature and humidity were all important factors affecting the quality of SSP. The condition control of "post fermentation" process has been paid more attention to in the past dynasties. In addition， the delicious SSP recognized in ancient times should be made from mold fermentation， and the breeding and application of fermented mold may be the key point to solve the quality problem of SSP. Therefore， based on the evaluation indexes of SSP in the past dynasties， it is of great significance to study and optimize the technological conditions such as strain， temperature and humidity in depth to improve the quality of SSP.

Based on the systematic retrieval and the reported components of Sojae Semen Nigrum and Sojae Semen Praeparatum, this study conducted in-depth analysis of conversion of components in the fermentation process, and discussed types and possible mec-hanisms of conversion of chemical components, so as to provide the basis for studying technology, medicinal ingredients and quality standards. According to the analysis, there is a certain degree of conversion of nutrients(like protein, sugar, lipid), bioactive substances(like isoflavones, saponins, γ-aminobutyric acid) and other substances(like nucleosides, melanoids, biamines, etc) in the process of fermentation.
