OBJECTIVETo see the change of capillary of heart in Athlete's Heart, so that to discover the mechanism of pathologic change.

METHOD18 male SD rats were separated randomly into control group (without any exercise), aerobic exercise group (swimming for 75 min every day), and overload group (swimming for 180 min with 5% weight of its body every day). After 5 days per week, 12 weeks, exercise training stopped and heart of rats were observed under Transmission Electron Microscope.

RESULTSIn aerobic exercise group, the capillary cavities in heart expand, the walls of capillary become thick; the number of mitochondrion increases; endothelium cells become active in growth. However, after overload exercise, the walls of capillary cockle and protuberances appear. The mitochondrion swell and the cristae become disorder. Most of endosomes expand and their number increases. The karyons become abnormity in shape and uniformity in electronic density, besides the nuclear envelope cockle. The basilar membranes become thick and unclear.

CONCLUSIONAfter exercise training, both physical and pathologic changes in heart capillary are found. In suitable exercises group, the capillaries change physically; the pathologic changes are becoming visible after overload exercise however.

1,2,3,4,6-penta-O-galloyl-D-glucose (PGG) is one of the main active compounds of Guizhi Fuling capsule. Molecularly imprinted polymers (MIP) have high affinity toward template molecules synthesized by molecularly imprinted technology for its specific combined sites, which can overcome the shortcoming of traditional separation methods, such as complex operation, low efficiency, using large quantity of solvent and environmental pollution. In this paper, surface molecularly imprinted polymer (SMIP) was prepared by surface imprinting with PGG as the template molecule. Its adsorption capacity was measured by the scatchard equation. The separation of PGG from Guizhi Fuling capsule at preparatived scale was achieved with molecularly imprinted polymer as stationary phase and the purity was 90.2% by HPLC. This method can be used to prepare PGG from Guizhi Fuling capsule with large capacity and is easy to operate. It provides a new method for efficient separation and purification for other natural products.

The study was aimed to analyse and enumerate the dendritic cells (DC) subsets in peripheral blood and bone marrow (BM) of healthy individuals in China by using 2 panel 4-color flow cytometry (FCM). The percentage and absolute number of Lin-HLA-DR+CD11chiBDCA1+ myeloid DC (mDC) and Lin-HLA-DR+CD123hiBDCA2+ plasmacytoid DC (pDC) were detected in 35 normal BM (NBM) and 29 normal peripheral blood (NPB), the results were compared with the Lin-HLA-DR+CD11chimDC and Lin-HLA-DR+CD123hi pDC obtained by 3-color FCM. The results indicated that both absolute count of DC subset and relative count of pDC in BM were decreased along with increase of age, the absolute count of DC subset in male BM was higher than that in femoral BM (p<0.05). The DC subsets in NBM and NPB were different whatever by 3 or 4-color cytometric analysis, there were more mDCs than pDCs in PB and the ratio of mDC to pDC was 2.70 and 2.31 respectively. In contrast, pDCs predominated in BM, the ratio of mDC to pDC in BM was 0.90 and 0.71 respectively. The quantity of DC subsets significantly correlated to both frequency (mDC r=0.86; pDC r=0.96, p<0.05) and absolute number (mDC r=0.95; pDC r=0.98, p<0.05) between 3 and 4-color cytometric analysis. The quantity of DC subsets in PB and BM were significantly different, counted by 3 and 4-color cytometric analysis except pDC in PB (p<0.001). The quantity of DC subsets were much higher by 3-color than that by 4-color analysis. Since some Lin-HLA-DR+CD11chimDC and Lin-HLA-DR+CD123hi pDC were BDCA1- and BDCA-2dim/- respectively, that more were in BM than in PB. It is concluded that the DC absolute enumeration is correlated with sample type, gender, age and total nucleated cells (p<0.05). 4-color antibody combination may help to identify the real DC subsets in BM. DC subsets in NBM and NPB are different, that more mDC are in PB whereas more pDC in BM.

OBJECTIVETo establish a mouse model of asthmatic airway remodeling and investigate the effects of 1,25-(OH)2D3 on airway structure and T cell immunoglobulin mucin protein-4 (TIM-4) expression in asthmatic mice.

METHODSThirty female mice (BALB/c strain) were randomly divided into control, asthma and 1,25-(OH)2D3 intervention groups. An asthmatic mouse model was induced using ovalbumin. Lung tissue of the mice was collected, mRNA expression of TIM-4 was evaluated by RT-PCR and airway remodeling and protein expression of TIM-4 were observed by hematoxylineosin staining and immunohistochemistry.

RESULTSTypical airway remodeling was found in the asthma group, and TIM-4 expression in this group was significantly higher than in the control group (105±9 vs 42±5; P<0.05). Compared with the asthma group, the 1,25-(OH)2D3 intervention group showed improvement in airway remodeling and a decrease in TIM-4 expression (78±6) (P<0.05).

CONCLUSIONSTIM-4 may be involved in the airway remodeling of mice. As a new type of immunoregulator, 1,25-(OH)2D3 can downregulate expression of TIM-4 in the lungs and improve airway remodeling in asthmatic mice.

The objective of this study was to investigate the immunophenotype of T-lineage acute lymphoid leukemia (T-ALL) and to find valuable immunologic markers in T-ALL diagnosis and therapy. Four-color multiparametric flow cytometry(FCM) with CD45/SSC gating was used for immunophenotyping of 95 patients with newly diagnosed T-ALL. The results demonstrated that T-ALL occurred more frequently in males younger than 30 years of age and was usually accompanied by a high WBC count and tumor mass at diagnosis. Univariate analysis showed an influence on achievement of CR1 for age (< 30 years) but not for WBC count and tumor mass. According to WHO (2008) classification of tumors of haematopoietic and lymphoid tissues, 87 patients with confirmed subtype included 27 cases of Pro-T-ALL (31.0%), 31 cases of Pre-T-ALL (35.6%), 23 cases of cortical-T-ALL (26.4%), 6 cases of medullary-T-ALL (6.9%). CD34 expression in Pro-T-ALL was significantly higher than that of Pre-T-ALL (p = 0.001). After the first chemotherapy, the complete remission rate in Pro-T-ALL was statistically lower than that of Pre-T-ALL. Besides, the complete remission rate of immature T-ALL (including Pro-T-ALL and Pre-T-ALL) was also significantly lower than that in mature T-ALL (including cortical-T-ALL and medullary-T-ALL). Myeloid antigen (CD13, CD33) expression was associated with T-ALL subtype and treatment effect. While 66.7% of CD13(+) patients belonged to Pre-T-ALL, most (60.0%) of CD33(+) patients were classified into Pro-T-ALL; CD13 expression had no effect on CR1 rate whereas CD33(+) patients had worse treatment effect compared with CD33(-) groups (p = 0.001). Notably, the expression of CD117 reached up to 26.7% and the positive cases were primarily distributed in pro-T-TAll and pre-T-ALL. It is found that CD117 expression in CD34(-) group was homogeneous and CD117 expression level was less than 10% in 73.2% patients, but CD117 expression level in CD34(+) group was not homogenous, in which group the CD117 expression levels < 10%, 10% - 20% and > 20% were 44.2%, 17.3% and 38.5% respectively. As compared with CD34(-) group, the proportion of patients with CD117 expression levels < 10%, > 20% in CD34(+) group was higher, and there was significant difference between these 2 group. It is concluded that immunophenotype has great value in T-ALL diagnosis, classification as well as treatment. Flow cytometry provides access to find valuable immunologic markers for T-ALL biological research.
