miRNAs were discovered less than a decade ago, and have emerged as important regulators of gene expression in mammals. A large number of miRNAs have been identified to be located within the intronic regions of protein-encoding genes(host genes) and called intronic miRNAs. The intronic miRNAs may play a key role in regulating the expression and function of their host genes due to the fact that most of them are co-expressed with the host genes. In this paper, the recent advances on the research on potential relationship between intronic miRNAs and their host genes are reviewed.

Objective To explore the effects of different doses of topiramate (TPM) on the expression of nerve cell adhesion molecule (NCAM) and growth-associated protein 43 (GAP- 43) mRNA in hippocampus of rats with epilepsy. MethodsForty-eight rats were randomly divided into normal control group, kainic acid (KA) group, 10 mg/kg TPM group, 40 mg/kg TPM group, 100 mg/kg TPM group and 400 mg/kg TPM group (n=8). The models of rats with epilepsy treated by different doses of TPM were established. The behavior of rats was observed, and the expression of NCAM and GAP- 43 mRNA in hippocampus of rats was determined by Real-time PCR. Results The expression of NCAM and GAP- 43 mRNA in KA group was significantly higher than that in normal control group (P<0.01), while there was no significant difference between 10 and 40 mg/kg TPM groups and KA group, that in 100 and 400 mg/kg TPM groups was significantly lower than that in KA group (P<0.01), and that in 400 mg/kg TPM group was significantly lower than that in 100 mg/kg TPM group (P<0.01). Conclusion KA can up-regulate the expression of NCAM and GAP- 43 mRNA in hippocampus of rats with epilepsy. Higher dose of TPM can inhibit the expression of NCAM and GAP- 43 mRNA, and the inhibitory effect is related with the dose of TPM.
5.Dynamic examination of the serum erythropoietin levels following ABO-incompatible allogeneic hematopoietic stem cell transplantation and its implications.
Journal of Experimental Hematology 2004;12(5):661-665
To evaluate the dynamic changes of erythropoietin (EPO) and its significance following ABO-incompatible allogeneic hematopoietic stem cell transplantation (allo-HSCT), sequential changes in serum EPO levels were measured by enzyme linked immunosorbent assay (ELISA) in 11 patients receiving allo-HSCT from ABO-incompatible donors. The results showed that the mean EPO level was markedly elevated and reached to its highest level at 0 day-2 week after allo-HSCT (233.73 +/- 81.95 mU/ml and 226.07 +/- 113.87 mU/ml respectively, P >0.05). Although the EPO levels were significantly lower at 1 month (128.49 +/- 108.92 mU/ml, P <0.05) and after the reversion of blood type (73.07 +/- 68.85 mU/ml, P <0.05), they were still elevated up to 2 months after allo-HSCT. The EPO levels always had significant positive correlation with the RBC transfusions. At 0 day and 4 week after allo-HSCT, the EPO levels had significant negative correlation with the Hb levels; at 6 and 8 week after allo-HSCT, the EPO levels had no relation with the Hb levels, they had significant positive correlation with the time of erythrocyte recovery and anti-A isoagglutinin titers at the same time. It is concluded that serum erythropoietin levels continuously increasing following ABO-incompatible allogeneic allo-HSCT suggest that exogenous recombinant human erythropoietin treatment for anemia may not be beneficial.

6.SDF-1/CXCR4 and multiple myeloma osteolytic bone lesions--review.
Journal of Experimental Hematology 2008;16(2):442-446
Multiple myeloma (MM) is a plasma cell malignancy characterized by the high capacity to induce bone destruction. Osteolytic bone lesions in MM patients mainly result from an increased bone resorption related to the stimulation of osteoclast recruitment and activity. SDF-1a would represent a potential role and may provide a suitable therapeutic target for MM-mediated osteolysis. In this article the structure of SDF-1/CXCR4, the expression of SDF-1/CXCR4 in bone microenvironment of MM patients and its effect on osteoclasts, relation of SDF-1/CXCR expression with osteolytic bone lesions and prognosis of MM, SDF-1/CXCR4 as potential target for treatment of myeloma-osteopathia were reviewed.

Objective To explore the clinical feature of Kimura disease complicated with nephrotic syndrome in children. Methods The clinical data from 4 children with Kimura disease complicated with nephrotic syndrome were retrospectively analyzed. Results In all of the 4 male children, level of serum IgE was increased but level of eosinophils was not increased in peripheral blood. The renal pathological manifestations were different among them. Two cases had acute tubular injury, one case had pathological changes in repeated renal biopsy, and one case had a little of eosinophils infiltration in renal interstitium. All of them were sensitive to oral hormone treatment. Except that one case had no relapse yet in short follow-up period, the other 3 cases had relapsed and all manifested as positive urinary protein without lymphadenectasis. The 3 cases with recurrence were treated by combined immunosuppressive agents, the palindromia of two cases were reduced which were combined with tacrolimus. Conclusion The Kimura disease complicated with nephrotic syndrome in children has a long course and different renal pathological manifestations. It is sensitive to hormone treatment but easy to relapse, and the treatment should be combined with immunosuppressive therapy. Tacrolimus may have the effect on reducing relapse and delaying the progress of renal pathology.

Background:Colonoscopy is considered as a standard method for detecting various kinds of colorectal polyps. However,conventional colonoscopy( CC)still has the chance to miss some lesions. Literatures have already reported that transparent hood assisted colonoscopy( THAC)can improve the detection of colorectal polyps. However,the effect of black hood assisted colonoscopy( BHAC)on detection of colorectal polyps is still unclear. Aims:To evaluate the effect of BHAC on detection of colorectal polyps. Methods:A total of 1 076 patients underwent CC and BHAC from Sept. 2014 to April 2015 at Huadong Hospital Affiliated to Fudan University were enrolled in this prospective randomized controlled study. Baseline characteristics,cecal intubation time,withdrawal time,number of polyps,detection rate of polyps,location, size,morphology and pathological diagnosis of polyps between two groups were compared. Results:Compared with CC group,cecal intubation time was significantly shorter in BHAC group than in CC group[(6. 31 ± 3. 51)min vs.(7. 05 ± 4. 15)min,P=0. 002]. No significant differences in withdrawal time and rate of cecal intubation were found between two groups(P>0. 05). Detection rate of polyps was significantly higher in BHAC group than in CC group(65. 4% vs. 48. 7%,P=0. 004). No significant differences in size,morphology of polyps were found between two groups(P>0. 05). Conclusions:Compared with CC,BHAC could significantly improve the detection of colorectal polyps,and shorten cecal intubation time.

This study investigated the protective effect of ATP on skeletal muscle satellite cells damaged by H2O2 in neonatal rats and the possible mechanism. The skeletal muscle satellite cells were randomly divided into four groups: normal group, model group (cells treated with 0.1 mmol/L H2O2 for 50 s), protection group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h, and then with 0.1 mmol/L H2O2 for 50 s), proliferation group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h). MTT assay, FITC+PI+DAPI fluorescent staining, Giemsa staining and immunofluorescence were performed to examine cell viability and apoptosis, and apoptosis-related proteins. The results showed that the survival rate of skeletal muscle satellite cells was decreased and the apoptosis rate was increased after H2O2 treatment (P<0.01). Different doses of ATP had different effects on skeletal muscle satellite cells damaged by H2O2: the survival rate of muscle satellite cells treated with ATP at 4, 2, or 1 mmol/L was increased. The protective effect was most profound on cells treated with 2 mmol/L ATP. Immunofluorescence showed that ATP could increase the number of Bcl-2-positive cells (P<0.01) and decrease the number of the Bax-positive cells (P<0.01). It was concluded that ATP could protect skeletal muscle satellite cells against H2O2 damage in neonatal rats, which may be attributed to the up-regulation of the expression of Bcl-2 and down-regulation of Bax, resulting in the suppression of apoptosis.
