OBJECTIVETo observe the effect of Fn-TPO gene modification on human bone marrow mesenchymal stem cells (MSCs).

METHODSRetroviral vector containing Fn-TPO gene was constructed and bone marrow MSCs was modified by this vector. The transcription of Fn-TPO gene in MSCs was observed. The proliferation capacities, hematopoietic cells adhering capacities and TPO secretion capacities of gene modified MSCs were assayed respectively. Cord blood CD34 cells were seeded on the gene modified MSCs layers and several essential growth factors were added. After co-culturing in vitro for 7 days, the number of CD34 cells and their colony forming capacities were assayed by flow cytometry and semisolid culture assay.

RESULTSRetroviral vector containing Fn-TPO gene was successfully constructed and bone marrow MSCs were modified by this vector. Fn-TPO gene was expressed by bone marrow MSCs after gene modification. The viability of MSCs had no significant difference between pre- and post-gene-modification [(7.18 +/- 0.89) 10(4)/ml vs. (6.92 +/- 0.77) 10(4)/ml, P > 0.05]. The hematopoietic cells adhering ability of gene modified bone marrow MSCs was reinforced(0. 188 +/- 0.018 vs. 0.167 +/- 0.017, P < 0.01). The concentration of TPO in the MSCs culture supernatant raised from (5.58 +/- 0.37) ng/ml to (7.46 +/- 0.59) ng/ml (P < 0.01) and did not significantly decline in a short-time period, but influenced by the growth status of MSCs. After co-culturing with gene modified MSCs for 7 days, the absolute number of nucleated cells, the percentage of CD34+ cells and the colony numbers of BFU-E, CFU-GM, CFU-GEMM were (29.9 +/- 2.7) x 10(4), (33.3 +/- 2.8)% , 109.3 +/- 4.1, 163.7 +/- 7.1, 13.3 +/- 1.5, respectively, being significantly higher than that co-cultured with non-modified MSCs.

CONCLUSIONSFn-TPO gene modification can improve the capacity of human bone marrow MSCs for hematopoietic cells adhering, TPO secretion and cord blood CD34 cells amplification.

The shape and structure of granules are controlled by the granulation process, which is one of the main factors to determine the nature of the solid dosage forms. In this article, three kinds of granules of a traditional Chinese medicine for improving appetite and promoting digestion, namely, Jianwei Granules, were prepared using granulation technologies as pendular granulation, high speed stirring granulation, and fluidized bed granulation and the powder properties of them were investigated. Meanwhile, synchrotron radiation X-ray computed micro tomography (SR-µCT) was applied to quantitatively determine the irregular internal structures of the granules. The three-dimensional (3D) structure models were obtained by 3D reconstruction, which were more accurately to characterize the three-dimensional structures of the particles through the quantitative data. The models were also used to quantitatively compare the structural differences of granules prepared by different granulation processes with the same formula, so as to characterize how the production process plays a role in the pharmaceutical behaviors of the granules. To focus on the irregularity of the particle structure, the box counting method was used to calculate the fractal dimensions of the granules. The results showed that the fractal dimension is more sensitive to reflect the minor differences in the structure features than the conventional parameters, and capable to specifically distinct granules in structure. It is proved that the fractal dimension could quantitatively characterize the structural information of irregular granules. It is the first time suggested by our research that the fractal dimension difference (Df,c) between two fractal dimension parameters, namely, the volume matrix fractal dimension and the surface matrix fractal dimension, is a new index to characterize granules with irregular structures and evaluate the effects of production processes on the structures of granules as a new indicator for the granulating process control and optimization.

AIM: To evaluate the anatomic and visual outcomes of 25-gauge vitrectomies combined with air tamponade for the treatment of idiopathic macular hole (IMH).METHODS: Thirty eyes of 27 patients with IMH were included in this prospective interventional study.All patients underwent 25-gauge pars plana vitrectomy (PPV) combined with phacoemulsification and air tamponade.Best corrected visual acuity (BCVA, logMAR), perimetry and multifocal electroretinography (mfERG) were conducted before and after the operation.Anatomical changes were evaluated with optical coherence tomography (OCT).RESULTS: The macular holes closed successfully in 28 eyes after the primary vitrectomy.The mean BCVA improved from 0.72±0.22 logMAR preoperatively to 0.29±0.18 logMAR postoperatively (P<0.001).In the visual field of central 10°, the average mean deviation (MD) decreased from-3.59±1.83 dB preoperatively to-2.51±1.36 dB postoperatively (P<0.001) and the average pattern standard deviation (PSD) decreased from 1.86±0.68 dB preoperatively to 1.33±0.32 dB postoperatively (P=0.001).The retinal response densities of mfERG in the foveal and perifoveal area increased significantly, and implicit times of rings 4-6 prolonged significantly (P<0.05).The symptom duration and baseline N1 amplitude densities at ring 1 had a significant impact on postoperative BCVA (P<0.001, P=0.001, respectively).CONCLUSION: The 25-gauge PPV and air tamponade with 1 day prone positioning produce favorable anatomic and functional outcomes.

The study aims to explore the effects and mechanisms of water extract of Potentilla anserina (PA) on myelosuppression mice induced by cyclophosphamide based on metabonomics. The myelosuppressive mouse model was established by injected with cyclophosphamide and treated with water extract of PA. Thymus and spleen indexes, peripheral hemogram and bone marrow nucleated cells of each group was detected. Bone marrow pathology analysis was performed by hematoxylin-eosin staining. The levels of interleukin 3 (IL-3), interleukin 6 (IL-6), erythropoietin (EPO), granulocyte colony stimulating factor (GM-CSF), malondialdehyde (MDA), superoxide dismutase (SOD) and catalase (CAT) in serum were measured. The changes of biomarkers and related metabolic pathways were analyzed by UPLC-Q-TOF/MS-based metabonomics. Animal experiments were approved by the Animal Ethics Committee of Southwest Minzu University. The high doses of PA could significantly improve the decrease of white blood cell (WBC), red blood cell (RBC) counts and hemoglobin (HGB) levels of mice induced by cyclophosphamide (P < 0.05), and significantly increase the number of nucleated cells and the area of hematopoietic tissue in femoral bone marrow. The medium and high doses of PA could significantly improve the serum levels of SOD, CAT, MDA, IL-6 and GM-CSF (P < 0.05), and have no significant effect on the expression of IL-3 and EPO (P > 0.05). Serum metabolomics analysis showed that the aqueous extracts of PA could alleviate myrosuppression by regulating the aminoacyl-tRNA, valine, leucine and isoleucine biosynthesis mediated by 13 different metabolites such as valine, leucine, asparagine and hydroxyisohexic acid. PA improve the inhibition of hematopoietic function in myelosuppression mouse, and its mechanisms may be related to anti-oxidation and promoting the expression of hematopoietic-related cytokines and regulating the related metabolic pathways.

A boy, aged 2 years and 4 months, had a sudden onset of blepharoptosis of the right eyelid, accompanied by the mouth deviated to the right side, drinking cough, nystagmus, and developmental regression. Cranial MRI showed softening lesions formed after infarction of the right dorsolateral medulla oblongata, while head CT angiography showed no imaging of the proximal part of the V4 segment of the right vertebral artery. The child was diagnosed with dorsolateral medulla oblongata syndrome and was treated with gamma globulin to regulate immune function, with mannitol to reduce neuronal edema, with low-molecular-weight heparin sodium to improve local hypercoagulation of occluded blood vessels, with hyperbaric oxygen to improve local ischemia and hypoxia and promote the recovery of brain function, and with neuromuscular electrical stimulation to promote the recovery of neuromuscular function. Before discharge, only mild right ataxia and Horner syndrome remained. This article reports the first case of infantile dorsolateral medulla oblongata syndrome and provides experience for the diagnosis and treatment of the disease.
