BACKGROUND:Moderate to severe burn and trauma, treatment of which has been paid equal attention to wound surface, is always a difficulty of clinical systemic treatment and has a poor prognosis. Anabolic hormones have acquired secure and good results in the treatment of burns in both animals and clinical patients. Although use of anabolic hormones is restricted by the doping management, but its androgen receptor and nuclear receptor coregulators are the newly emerging areas of interests in the field of gene regulation mechanism in recent years. OBJECTIVE:To investigate the effect of nandrolone phenylpropionate on androgen receptor-mediated transcriptional regulation of target gene in rat scald models. METHODS: Thirty-six rats were randomly divided into nandrolone phenylpropionate, model and control groups. In the nandrolone phenylpropionate and model groups, rats were subjected to a 20% total body surface area second-degree scald injury by hot water. Two days after model preparation, rats in these two groups were intramuscularly injected with nandrolone phenylpropionate and saline, once every other day, for a total of 21 days. RESULTS AND CONCLUSION:The gene expression levels of steroid receptor coactivator-1 and insulin-like growth factor 1 in the rat livers and gonads (testes, ovaries) were significantly different between the nandrolone phenylpropionate and model groups (P < 0.05), except steroid receptor coactivator-1 in the liver. There were no significant differences in steroid receptor coactivator-1, c-myc and insulin-like growth factor 1 in the rat livers and gonads (testes, ovaries) between model and control groups (P < 0.05). The results demonstrate that nandrolone phenylpropionate has different effects on the gene expression of steroid receptor coactivator-1, c-myc and insulin-like growth factor 1 in different tissues under different physiological and pathological conditions.

Interstitial cell of Cajal (ICC) is a kind of special interstitial cell in the gastrointestinal tract,which has close connection with the smooth muscle cells and neuron cells.It is involved in gastrointestinal motility and nerve signal transduction and is considered as the pacemaker cell of slow wave of gastrointestinal tract.ICC which exists in the non-gastrointestinal organs such as biliary tract,urethra,bladder and so on is named interstitial Cajal-like cell (ICLC).This article will review the progress in the research of ICLC in the biliary system in terms of their morphology,identification,classification,function,distribution and related biliary diseases.

Objective Delivery of oxygen in tissues is limited in the space where oxygen must diffuse between the vascular and the surrounding tissues. Normal capillaries are relatively straight and well spaced, in contrast, the tumor vascular networks usually display more irregularity and the vessel wall shows higher permeability and less elasticity. The purpose of this study was to investigate the effect of capillary elasticity and tortuosity on the oxygen distribution and make further investigation on the mechanism of the formation of hypoxic regions in tumor. Method One-dimensional capillary model was coupled with the oxygen diffusion model. Oxygen transport was investigated in a Krogh and tortuous tissue model. The capillarygeometrywas obtained bythe one-dimensional model and transferred to the tissue model. Finite element method was employed in the analysis. Result The capillary radii along the flow direction under pressures were obtained for different initial radii and the oxygen distribution in the Krogh cylinder tissue model and the model with a tortuous capillary were computed. Conclusions when the capillary radius is small, the effect of vessel elasticity may have not significant effect on the oxygen distribution. However, with the capillary radius increasing, the effect on the oxygen transport becomes obvious. Moreover, with the tortuosity of the capillary increasing, the oxygen distribution becomes more heterogeneous, which is in agreement with the result in available reference. This work will be helpful to the investigation of oxygen transport within tumor.

AIM: To investigate therapeutic effects of combination therapy for neovascular glaucoma ( NVG) .
METHODS: This retrospective study comprised 34 eyes of 34 patients who suffered from NVG. All patients were assigned to group A, B, C and D according to the different combination therapies. Group A ( 11 eyes of 11 patients ) was treated with intravitreal injection of ranibizumab and panretinal photocoagulation ( PRP ) . Group B ( 10 eyes of 10 patients ) was treated with transcleral cyclophotocoagulation and PRP. Group C ( 6 eyes of 6 patients) was treated with 3 therapies together. Group D (7 eyes of 7 patients) was treated with 810nm transcleral cyclophotocoagulation and soft gas-permeable contact lenses. All the patients were followed-up for 1a. The best- corrected visual acuity ( BCVA ) , intraocular pressure ( IOP ) were recorded and analyzed prior to operation and 1, 4wk, 6 and 12mo after operation.
RESULTS: All the post treatment IOP decreased significantly ( P<0. 05 ) from the values before therapy, and the IOP values after 4wk, 6, 12mo were not significantly different ( P > 0. 05 ) in statistics. Most patients' IOP can be controlled below 23mmHg after combination therapy. The visual acuity in group A after 1, 4wk, 6mo compared with those before treatment was significantly increased ( P<0. 05 ) in statistics and other groups did not significantly change before and after treatment (P>0. 05). Anterior chamber bleeding occurred to 2 cases after 1wk of transcleral cyclophotocoagulation. No other ocular or systemic adverse events were found during the follow-up duration.
CONCLUSION: After the combination of intraocular injection of the anti - VEGF drugs, 810nm laser cyclophotocoagulation and PRP, most patients with NVG disease can be effectively treated, can effectively control IOP, and retain part of the visual function, significantly improve the quality of life. In the short - term, combination therapy is safe and effective for NVG, which provides us an available strategy to conquer NVG by simply programmable operation and less suffering.
