BACKGROUND:Decreased function and reduced number of CD4+CD25+regulatory T cells have been considered the major manifestation of immunity dysfunction in children with primary nephrotic syndrome. Bone marrow mesenchymal stem cells have immunoregulation effects, which up-regulate CD4+CD25+regulatory T cells, inhibit proliferation of lymphocytes, and have been widely used in many immune diseases.
OBJECTIVE:To investigate the effects of bone marrow mesenchymal stem celltransplantation on the CD4+CD25+regulatory T cells of peripheral blood in rats with primary nephrotic syndrome.
METHODS:Bone marrow mesenchymal stem cells from six Sprague-Dawley rats were isolated, passaged and utilized for cellsuspension preparation. At the third passage, bone marrow mesenchymal stem cells were used for transplantation. The remaining 30 rats were randomly and equal y divided into three groups:normal group, normal saline infusion group, and bone marrow mesenchymal stem cells group. The rat models of primary nephrotic syndrome were established by single injection of adriamycin intravenously through tail vein in the latter two groups. Rats were then treated with bone marrow mesenchymal stem cells (1×10 7 ) (bone marrow mesenchymal stem cells group) or normal saline (normal saline infusion group) through tail vein at the same time after adriamycin administration. The normal group received no treatment.
RESULTS AND CONCLUSION:Compared with the normal group, rats in the normal saline infusion group developed nephropathy characterized by ascites, proteinuria, hypoalbuminemia, hypercholastero-lnemia, and progressive renal injury. However, the proteinurine and clinical severity in bone marrow mesenchymal stem cells group were significantly ameliorated after treatment with bone marrow mesenchymal stem cells. CD4+CD25+Treg/CD4+Treg in the peripheral blood in the bone marrow mesenchymal stem cells group and normal saline infusion group were significantly higher than that in the normal group at 28 days after model establishment (P<0.05), while there was no significant difference between bone marrow mesenchymal stem cells group and normal saline infusion group (P>0.05). The expression of FoxP3 mRNA in the peripheral blood mononuclear cells of the bone marrow mesenchymal stem cells group was significantly higher than that in the normal saline infusion group and normal group (P<0.05). The bone marrow mesenchymal stem cells play a protective effect in rats with primary nephrotic syndrome, which may be related to the increase of local expression of FoxP3 and generation of CD4+CD25+Treg.

Objective To study the risk factors influencing the prognosis in the children patients with acute gastrointestinal dysfunction and to seek their therapeutic measures. Methods The clinical data of 125 cases patients with acute gastrointestinal dysfunction were retrospectively analyzed. The risk factors possibly influencing the prognosis were analyzed by multivariate statistical Logistic analysis. Results Among 125 children patients, 61 cases died, and the mortality rate was 48.8%. Logistic regression analysis indicated that poor circulation, cardiovascular system failure, hepatic failure, brain failure were significant risk factors of death associated with acute gastrointestinal dysfunction. (OR = 4.156, 3.330, 6.903, P<0.05 or<0.01). Conclusions Poor circulation, cardiovascular system failure, hepatic failure and brain failure are significant risk factors of death associated with acute gastrointestinal dysfunction.

BACKGROUND:Nowadays, gene therapy has become a new trend for disease therapy and brought promise for some refractory diseases. Its key is to choose proper cel s, genes and vectors. OBJECTIVE:To use recombinant adeno-associated virus mediatedβ-nerve growth factor (β-NGF) to transfect rat bone marrow-derived endothelial progenitor cel s in vitro, and to investigate the effect ofβ-NGF expression on the proliferation of endothelial progenitor cel s. METHODS:The endothelial progenitor cel s were isolated, cultured and identified from the bone marrow of rats. Empty vector or recombinant adenovirus-associated virus containingβ-NGF gene was transferred into endothelial progenitor cel s. We examined the transfection efficiency by fluorescence expression of green fluorescent protein. Expression ofβ-NGF protein was detected using ELISA, and its effect on the proliferation of endothelial progenitor cel s was determined using MTT method. RESULTS AND CONCLUSION:Rat endothelial progenitor cel s were isolated and cultured successful y in vitro and were identified positive by the function of cel s and immunofluorescence staining. The endothelial progenitor cel s were infected directly by the recombinant adenovirus-associated virus containingβ-NGF gene with an efficiency of 65.3%.β-NGF protein was detected in the culture supernatant of transfected endothelial progenitor cel s, which reached a high level at 10 days after gene transfection. Furthermore, there was noβ-NGF protein in the blank and empty vector groups. After transfection, the proliferative ability of endothelial progenitor cel s was increased, which was significantly higher than the blank and empty vector groups (P<0.05). But there was no difference between the latter two groups (P>0.05). These findings suggest that recombinant adenovirus-associated virus containingβ-NGF gene can be successful y transferred into rat bone marrow-derived endothelial progenitor cel s and promote the proliferation of endothelial progenitor cel s.

Large vessel vasculitis is characterized by chronic inflammation within the aortic wall and its major branches. The inflammation is considered to occur as a result of immune dysregulation. Hematologic malignancy is one of the rare causes of secondary vasculitis. Herein, we report a rare case of large vessel vasculitis associated with acute myeloid leukemia mimicking primary vasculitis.

The vast majority of malignant tumors involving the vagina are secondary spread from primary malignant lesion of the cervix uteri, the sigmoid colon, the bladder and the vulva. Primary invasive carcinoma of the vagina remains among the rare gynecologic malignant tumor. The diagnosis of primary carcinoma of the vagina requires that the cervix and the vulva be intact and no clinical evidence of other primary tumors exist. Greater than 80-90% of all vaginal tumors are squamous cell type. We experienced two cases of primary vaginal cancer of 68 years old woman without any other gynecologic disease and 67 years old woman after hysterectomy for benign desease. We presented these cases with a brief review of related literatures.

BACKGROUND: A co-inhibitory molecule, B7-H4, is believed to negatively regulate T cell immunity by suppressing T cell proliferation and inhibiting cytokine production. However, the mechanism behind B7-H4-mediated tolerance remains unclear. METHODS: Balb/c (H-2(d)) mice were fed with dendritic cell line, DC2.4 (H-2(b)) every day for 10 days. Meantime, mice were hydrodynamically injected with recombinant plasmid expressing B7-H4 fusion protein (B7-H4.hFc) or hFc via tail vein. One day after last feeding, mice were immunized with allogeneic B6 spleen cells. 14 days following immunization, mice were challenged with B6 spleen cells to ear back and the ear swelling was determined the next day. Subsequently, a mixed lymphocyte reaction (MLR) was also performed and cytokines profiles from the reaction were examined by sandwich ELISA. Frequency of immunosuppressive cell population was assayed with flow cytometry and mRNA for FoxP3 was determined by RT-PCR. RESULTS: Tolerant mice given plasmid expressing B7-H4.hFc showed a significant reduction in ear swelling compared to control mice. In addition, T cells from mice given B7-H4.hFc plasmid revealed a significant hyporesponsiveness of T cells against allogeneic spleen cells and showed a significant decrease in Th1 and Th2 cytokines such as IFN-gamma, IL-5, and TNF-alpha. Interestingly, flow cytometric analysis showed that the frequency of CD4+CD25+FoxP3+ Tregs in spleen was increased in tolerant mice given recombinant B7-H4.hFc plasmid compared to control group. CONCLUSION: Our results demonstrate that B7-H4 synergistically potentiates oral tolerance induced by allogeneic cells by increasing the frequency of FoxP3+ CD4+CD25+ Treg and reducing Th1 and Th2 cytokine production.

Objective: This study aimed to investigate the blood-brain barrier (BBB) disruption in mild traumatic brain injury (mTBI) patients with post-concussion syndrome (PCS) using dynamic contrast-enhanced (DCE) magnetic resonance (MR) imaging and automatic whole brain segmentation. Materials and Methods: Forty-two consecutive mTBI patients with PCS who had undergone post-traumatic MR imaging, including DCE MR imaging, between October 2016 and April 2018, and 29 controls with DCE MR imaging were included in this retrospective study. After performing three-dimensional T1-based brain segmentation with FreeSurfer software (Laboratory for Computational Neuroimaging), the mean Ktrans and vp from DCE MR imaging (derived using the Patlak model and extended Tofts and Kermode model) were analyzed in the bilateral cerebral/cerebellar cortex, bilateral cerebral/cerebellar white matter (WM), and brainstem. Ktrans values of the mTBI patients and controls were calculated using both models to identify the model that better reflected the increased permeability owing to mTBI (tendency toward higher Ktrans values in mTBI patients than in controls). The Mann-Whitney U test and Spearman rank correlation test were performed to compare the mean Ktrans and vp between the two groups and correlate Ktrans and vp with neuropsychological tests for mTBI patients. Results: Increased permeability owing to mTBI was observed in the Patlak model but not in the extended Tofts and Kermode model. In the Patlak model, the mean Ktrans in the bilateral cerebral cortex was significantly higher in mTBI patients than in controls (p = 0.042). The mean vp values in the bilateral cerebellar WM and brainstem were significantly lower in mTBI patients than in controls (p = 0.009 and p = 0.011, respectively). The mean Ktrans of the bilateral cerebral cortex was significantly higher in patients with atypical performance in the auditory continuous performance test (commission errors) than in average or good performers (p = 0.041). Conclusion BBB disruption, as reflected by the increased Ktrans and decreased vp values from the Patlak model, was observed throughout the bilateral cerebral cortex, bilateral cerebellar WM, and brainstem in mTBI patients with PCS.
