Conclusion Shuangteng Bitong Cataplasm can inhibit inflammatory reaction and regulate the expressions of relevant factors in synovial tissues to realize the anti-flammatory effects.

The purpose of this study was to investigate the influence of nitro oxide (NO) from mesenchymal stem cells (MSC) on the proliferative responses of allogeneic lymphocytes and its mechanism. MSCs were isolated and cultured from human bone marrow. Selected surface antigens of MSCs were detected by flow cytometry and their morphologic characteristics were determined by microscopy. Mitomycin C-treated MSCs were plated in dishes and then mixed lymphocyte cultures (MLC) were set up. After 4 days, lymphocyte proliferation was determined by CCK-8 assays; NO secretion in coculture supernatant was determined by Griess reagent kit; the level of FOXP3 mRNA expression was detected by real-time quantitative PCR. The results indicated that in MSC/MLC coculture experiment, the lymphocyte proliferation decreased significantly with of IOD value 0.49+/-0.03, NO production increased obviously (21.05+/-1.14 micromol/L) and FOXP3 mRNA expression was increased [(1.56+/-0.34)%] as compared with MLC coculture without MSC. There were significant difference between these two groups. It is concluded that NO production in human MSC culture up-regulates FOXP3 mRNA expression and thus inhibits lymphocyte proliferation response.

OBJECTIVETo investigate the corrective results of congenital scoliosis with type II split spinal cord malformation.

METHODSBy reviewing the medical records and roentgenograms of congenital scoliosis patients with type II split spinal cord malformation that underwent corrective surgery, septum location and length, curve type, coronal and sagittal Cobb's angles, apical vertebral rotation and translation, and trunk shift were measured and analyzed.

RESULTSA total of 23 congenital scoliosis patients with type II split spinal cord malformation were studied, 6 cases were due to failure of segmentation, 8 cases due to failure of formation, and the remaining 9 cases due to mixed defects. The fibrous septums were located in the thoracic spine in 8 patients, lumbar spine in 4 patients, thoracic and lumbar spine in 10 patients, and from cervical to lumbar spine in 1 patient The septum extended an average of 4.9 segments. Corrective surgeries included anterior correction with instrumentation in 2 patients, posterior correction with instrumentation in 11 patients, anterior release and posterior correction with instrumentation in 6 patients, anterior and posterior resection of the hemivertebra and posterior correction with instrumentation in 4 patients. The pre- and postoperative coronal Cobb's angles, apical vertebral translations, apical vertebral rotations, trunk shifts were 61.9 degrees and 32.5 degrees (P < 0.001), 48.9 mm and 31.5 mm (P < 0.001), 1.2 and 1.1, 12.7 mm and 8.2 mm, respectively. The average correction rate of coronal Cobb's angle was 47.5%. The sagittal balance was also well improved. The fibrous septums were all left in situ. There was no neurological complication.

CONCLUSIONFor congenital scoliosis with type II split spinal cord malformation, positive correction results with no neurological complication may be obtained without resection of the fibrous septum.

The objective of this study was to analyze the level of bcr-abl mRNA in peripheral blood (PB) after allogeneic stem cell transplantation (allo-SCT) in chronic myeloid leukemia patients, providing a experimental basis for diagnosing early relapse. bcr-abl mRNA levels in 78 PB and bone marrow (BM) samples from 15 CML patients after allo-SCT were detected by using real-time quantitative PCR. The results indicated that levels of bcr-abl mRNA before transplantation were high (median 29.303%) and decreased greatly (median 0) at the first month after allo-SCT. During the first year after allo-SCT, the patterns of serial bcr-abl transcripts varied in number, but the overall bcr-abl transcript levels significantly decreased at 6 months after allo-SCT. Majority of patients with undetectable or very low levels of bcr-abl mRNA were monitored after 1 year following transplantation. The hematological features of BM and PB in all detected patients remained normal. PB and BM bcr-abl values were not different significantly and had the similar trend of changes. It is concluded that the bcr-abl mRNA levels in CML patients change greatly early after allograft. Serial monitoring measurements for bcr-abl mRNA contribute to understanding the trend of change and effect of transplantation, also can be a guidance for starting therapy. But detectable levels of bcr-abl mRNA during the first 6 months do not indicate relapse. Measurements of bcr-abl mRNA of PB may be more suitable for routine monitoring long-term disease status in CML after allo-HSCT.

Objective:To explore the technical feasibility of CT feature tracking (CT-FT) technique in evaluating left ventricular myocardial strain and evaluate the change of myocardial strain in patients with coronary heart disease.Methods:Eighty-one patients with coronary heart disease (lesion group) and 33 patients with normal coronary artery (control group) matched with age and sex were collected retrospectively from the Second Affiliated Hospital of Nanchang University from April 2019 to October 2020. The lesion group was first divided into single vessel stenosis group (42 cases) and multi vessel stenosis group (39 cases) according to the number of coronary artery stenosis branches, and the global myocardial strains of the left ventricle between the groups were analyzed. Lesion site included the left anterior descending branch (LAD), right coronary artery (RCA) and left circumflex branch (LCX), respectively. According to the degree of vascular stenosis, the lesion groups were divided into normal group, mild stenosis group, moderate stenosis group and severe stenosis group. The segmental myocardial strains of the branch segment of LAD, RCA or LCX were analyzed between groups. All CCTA examinations were performed with retrospective electrocardiogram gating. CVI 42 cardiac postprocessing software was used to obtain myocardial strain parameters, including global peak longitudinal strain (GPLS), global peak circumferential strain (GPCS), global peak radial strain (GPRS), and the segmental myocardial strains of the branch segment of LAD, RCA or LCX. The segmental myocardial strains included the peak longitudinal strain (PLS), peak circumferential strain (PCS) and peak radial strain (PRS). One way ANOVA or Kruskal Wallis H test were used for multi group analysis. Results:With the increased number of coronary artery stenosis branches, the absolute value of GPLS gradually decreased. The GPLS of the control group, single vessel stenosis group and multi vessel stenosis group were -14.1%±2.7%, -11.5%±2.3% and -8.8%±2.0%, respectively. The difference of GPLS between the 3 groups or any 2 groups was statistically significant (all P<0.001). The absolute values of GPRS and GPRS in multi vessel stenosis group were significantly lower than those in control group and single vessel stenosis group (all P<0.001). There was no significant difference in GPRS or GPRS between single vessel stenosis group and control group ( P=0.083, 0.118). And there were significant differences in the segmental myocardial strains of the branch segment of LAD, RCA or LCX among 3 groups ( P<0.001). In severe stenosis group, the absolute values of PRS, PCS and PLS in LAD, RCA or LCX were significantly lower than those in moderate stenosis group, mild stenosis group and normal group (all P<0.05). In the moderate stenosis group, the absolute value of PLS in each branch segment was lower than that of the mild stenosis and normal group (all P<0.05), and there was no significant difference in any 2 other myocardial strain parameters of each branch (all P>0.05). Conclusions:CT-FT technique was feasible to evaluate left ventricular myocardial function. With the increased number or degree of coronary artery stenosis, the global and segmental myocardial strain parameters of left ventricle gradually decreased, and the longitudinal strain was more sensitive.
