Objective:To explore the effect of endothelin-1 on atrial ifbrosis in patients with atrial ifbrillation (AF).
Methods: A total of 72 patients with thoracotomy were studied, the patients were divided into 2 groups:AF group, n=39 and Sinus rhythm (SR) group, n=33. The mRNA and protein expressions of endothelin-1 (ET-1), platelet derived growth factor-B (PDGF-B) and collagen I (COL1) in right atrial appendage (RAA) tissue were measured by RT-PCR and Western blot analysis;meanwhile, the impact of ET-1 stimulation and non-selective ET-1 receptor antagonist (sulfafurazole SIZ) on PDGF-B mRNA and protein expressions in H9c2 cells were measured.
Results: ①The RAA tissue mRNA and protein expressions in AF group were higher than those in SR group, as for ET-1 (2.830 ± 2.276) vs (1.220 ± 0.887) and (0.835 ± 0.241) vs (0.286 ± 0.083), both P<0.01;for PDGF-B (2.568 ± 2.348) vs (1.567 ± 0.831) and (0.807±0.241) vs (0.381 ± 0.105), both P<0.05;for COL1α1 (3.376 ± 1.598) vs (1.629 ± 0.833) and (0.652 ± 0.210) vs (0.312 ± 0.12), both P<0.05.②The protein expressions of ET-1 and COL1 had positive correlation (r=0.580, P<0.01).③ET-1 promoted PDGF-B secretion in H9c2 cells in a concentration and time-dependent manner;SIZ could reduce such promotion.
Conclusion: ET-1 plays an important role in AF occurrence which might be related to PDGF-B regulation.

Objective:
To explore the relationship between adolescents gratitude and social adaptation, as well as the mediating roles of school boding including support from teacher, peers and school belonging in the association.
Methods:
A total of 1 304 adolescents from 6 schools and colleges in Xuzhou were investigated with Adolescent Gratitude Scale, School Bonding Scale and Social Adaptation Scale.
Results:
Adolescent gratitude varied significantly in gender and grade, with girl’s gratitude significantly higher than that of boys(F=38.09, P<0.01). Adolescent gratitude increased as adolescents grew older, and was positively associated with social adaptation(r=0.26, P<0.01). School bonding partially mediated the relationship between adolescent gratitude with social adaptation(β=0.06).
Conclusion
School bonding plays a partial mediating role in the relationship between adolescent gratitude and social adaptation,adolescent gratitude can make a direct influence on social adaptation,and can also play an indirect role through school bonding.

OBJECTIVE: To investigate the effects and its mechanism of calcium phosphate bone cement (CPC) loading total flavonoids of Davallia mariesii on osteogenic differentiation of induced membrane in rats. METHODS: Drug-loading CPC and drug-loading polymethyl methacrylate (PMMA) cement were prepared with the contents of Qianggu capsules (total flavonoids of D. mariesii as active ingredient) using CPC and PMMA cement as carrier. Totally 64 male SD rats were randomly divided into drug-loading CPC group, drug-loading PMMA cement group, no-drug CPC group, no-drug PMMA cement group, with 16 rats in each group. The femur of rats was separated and osteotomized to prepare bone defect model, and then the corresponding bone cement was implanted. Four weeks after modeling, the induced membranes of rats were cut and protected. Bone cement was taken out and autogenous cancellous bone was implanted. At the 4th week after modeling, X-ray photographs were taken on the hind limb bones of rats. At the 4th week after modeling and 6th week after bone grafting, induced membranes and new bone were taken from the bone defect area of rats respectively. HE staining was used to observe the morphology of induced membrane, and the width of bone rabecular and the number of osteoblasts of new bone tissue were measured. Immunohistochemistry was used to detect the protein expression of BMP-2 and VEGF in induced membrane. Western blotting assay was used to detect the protein expression of Smad1, Smad4 and Smad7 in new bone. RESULTS: Compared with other 3 groups, the degradation of bone cement in drug-loading CPC group was more obvious in the bone defect areas, which showed that the formation of induced membrane was observed and the bone defect areas were smaller; capillary endothelial cells were abundant and orderly arranged in the induced membranes, and the width of bone trabeculae and the number of osteoblasts in the new bone tissue increased significantly (P<0.05); the protein expression of BMP-2 and VEGF in the induced membrane, the protein expression of Smad1, Smad4 and Smad7 in new bone were increased significantly (P<0.05). CONCLUSIONS: CPC loading total flavonoids of D. mariesii promotes the formation of induced membrane osteoblast in bone defect model rats, which may be associated with regulating osteoblast differentiation by activating BMP-2/Smad pathway; at the same time, it can promote bone healing by promoting the differentiation of vascular endothelial cells, accelerating the formation of capillary network and increasing the expression of vascular endothelial cells.

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells (T-bet) and GATA binding protein 3 (GATA3). MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective, double-blind and randomized control methods, the patients were randomized into three groups: kidney deficiency group, Qi and blood deficiency group, and control group. The three groups were respectively treated with Bushen Shengxue prescription granule, Yiqi Yangxue prescription granule, and Placebo (half the dose of Bushen Shengxue formula granules). In addition, all of them were given oral cyclosporin and androgen. The treatment lasted 6 months, with 3 months as a course. The blood routine indexes, T cell subsets, and fusion genes T-bet and GATA3 before and after treatment were analyzed, and the safety indexes were monitored. ResultDuring the observation, a total of 75 cases dropped out and 18 were rejected. Finally, 161 cases in the kidney deficiency group, 164 in the Qi and blood deficiency group, and 167 in the control group were included. After 6 months of treatment, the total effective rate was 98.8% (159/161) in the kidney deficiency group, which was higher than the 79.9% (131/164) in the Qi and blood deficiency group (χ2=30.135, P<0.01) and the 61.7% (103/167) in the control group (χ2=70.126, P<0.01). The total effective rate was higher in the Qi and blood deficiency group than in the control group (χ2=13.232, P<0.01). After treatment, the hemoglobin (HGB) content increased significantly in three groups (P<0.05) as compared with that before treatment, particularly the kidney deficiency group (P<0.01). After treatment, the white blood cell (WBC) count and platelet (PLT) count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group (P<0.01). There was no specific difference in neutrophils (ANC) after treatment among the three groups. At the same time point, the level of T helper type 1 (Th1) cells, Th1/Th2 ratio (P<0.05), level of CD4+, and CD4+/CD8+ ratio (P<0.05) were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19-, HLA/DR+, and CD25+ between the kidney deficiency group and the other two groups, but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group (P<0.05). ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism, inhibiting the activity of immune system, modulating T cell subsets, suppressing Th1 and CD4+, and promoting bone marrow hematopoiesis. Moreover, it is safe with little side effects, which is worthy of further promotion.
