2. Expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus-associated glomerulonephritis
Academic Journal of Second Military Medical University 2010;28(5):492-494
Objective: To investigate the expression of Bcl-2 and Bax in renal tissues of patients with hepatitis B virus-associated glomerulonephritis (HBV-GN). Methods: Twenty HBV-GN specimens with complete nephrology data and 10 normal renal specimens were randomly chosen for the present study. Cell apoptosis was detected by means of terminal deoxynucleotidyl transferase mediated d-UTP nick end labeling (TUNEL) and the apoptotic index was calculated; immunohistochemistry was used to detect the protein expression of Bax and Bcl-2. Results: The apoptotic index in HBV-GN group was obviously higher than that of the control group; the apoptotic cells were mainly distributed in the proximal and distal renal tubules and the collecting duct epithelial cells, seldom seen in the glomerular cells. The expression of Bcl-2 in HBV-GN patients was predominately present in the renal tubular epithelia cells (positive in the plasma, membrane and nuclear); the expression of Bax was found in both glomerular cells and renal tubular cells, mainly in tubular epithelial cells, seldom seen in Bowman's capsule or glomerular mesangial region. Conclusion: Apoptosis in the kidney of HBV-GN patients mainly occurs in the renal tubular epithelial cells; expression of Bax and Bcl-2 is mainly in the renal tubular epithelial cells, suggesting that the injury of tubular interstitial damage may be one of the important factors for the development of HBV-GN.

The mechanism of long chain non-coding RNA (lncRNA) is diverse. LncRNA can regulate the expression of genes at multiple levels and is closely related to some pathological process, such as tumor formation, viral replication, inflammatory damage, etc. The abnormal expression of lncRNA is involved in the patho-physiological changes of the disease, and plays a key role in many links, such as the stability of mRNA, the regulation of translation level, protein transport, RNA processing and modification, and so on. The development of sepsis inflammatory injury is a complex process involving multiple genes and pathways, in which the abnormal structure and expression of many encoding genes or non-coding genes exist.This paper review the research progress on lncRNA in the regulation of chondriokinesis, pro-inflammatory cytokines, calcium ion transport, nuclear factor-κB (NF-κB) in signal pathway and other inflammatory lesions, which may provide a new method for the diagnosis and treatment of sepsis.

Objective To investigate the effect of acarbose on waist circumference (WC) in patients with IGR. Methods A total of 46 subjects with IGT (2 hPG>7.8 mmol/L) were selected in this study. All the subjects were given diet and exercise treatment for half a month and then treated with acarbose for 3 months in combination with life style modification. Self-paired method was adopted to compare islet βcell function and WC before and after the treatment. Results After acarbose treatment for 3 months ,islet βcell function were markedly improved. Insulin secretion of Fins and 2 hIns decreased ,early insulin secretion index (ΔI30/ΔG30 ) significantly increased ,and BMI and WC were reduced significantly (P<0.05) . Multiple regression analysis showed that there was correlation between WC and TG ,insulin resistance index (HOMA-IR) and islet β-cell function index (HOMA-β) (P< 0.05). Conclusion Acarbose in combination with life style modification can improve islet β-cell function in patients with IGR and reduce WC and abdominal fat accumulation as well.

Objective To investigate whether TNF-α can promote, but TGF-β can reduce Gli2 expression in primary leukemia cells. Methods (1)Western blot was used to detect Gli2 protein expression in leukemic cells. (2)Primary leukemia cells were treated with TGF-β1 or TNF-α,and expressions of Gli2 and TGF-βR were detected. (3)Primary leukemia cells were treated with TGF-β1,TNF-α or/and SIS3, and Gli2 protein expression was detected. Results (1)The primary leukemia cells could express Gli2 protein. (2)Significant reduction of Gli2 mRNA was observed in 1 ~ 10 ng/mL TGF-β1-treated primary leukemia cells for 12 ~ 24 h, No significant differences of Gli2 mRNA was found between the control group and TNF-α group. (3)Protein expresson of TGF-βRⅠand TGF-βRⅡ in 5 ng/mL TNF-α-treated primary leukemia cells for 24 h was higher than that of the control group. (4)Gli2 portein expression was lower in TGF-β1 with or without TNF-α-treated primary leukemia cells for 24 h than that in the control group, and Gli2 portein expression in the TGF-β1 plus TNF-α group was lower than that in TGF-β1 group. Conclusion Combinations of TGF-β and TNF-α can efficiently inhibit Gli2 expression than TGF-β alone in primary leukemia cells.
