APOBEC3 is a class of cytidine deaminase, which is considered as a new member of the innate immune system, and APOBEC3G belongs to this family. The research about APOBEC3G is a new direction of innate immune defense mechanism against virus. APOBEC3G has the restrictive activity on many viral replications, which deaminates dC to dU in the viral genome and then induces extensive hypermutation. APOBEC3G can also interrupt viral replication at several phases such as reverse transcription, replication, nucleocapsid and so on by non-deamination mechanisms. However, virus can encode viral proteins to counteract the restriction activity of APOBEC3G. Elucidation of the antagonistic interaction between APOBEC3G and the virus will be contributed to development of new antiviral drugs in the future.

Objective To study the incidence and risk factors of retinopathy of prematurity (ROP) in a single tertiary center during different times(Phase 1:2009 to 2011;Phase 2:2012 to 2014). Methods From 2009 to 2014, fundus examinations were performed on premature infants admitted to NICU of our hospital. The incidence and risk factors of ROP were compared between the two phases. Results During Phase 1,68 (11. 1% ) cases were diagnosed with ROP among 614 premature infants. During Phase 2, 121 (15. 2% ) cases were diagnosed with ROP among 794 premature infants. The incidences of ROP between the two phases were significantly different (P <0. 05). During Phase 1 and 2, 10 (14. 7% ) infants and 12 (9. 9% ) infants were diagnosed with Grade 3 and above or threshold ROP, respectively. The incidence of Grade 3 and above or threshold ROP between the two phases were also significantly different (P < 0. 05). Logistic analysis demonstrated that gestational age(GA), birth weight (BW), duration of oxygen therapy and mechanical ventilation(MV) were independent risk factors during hase 1, whereas GA, MV and blood transfusion were independent risk factors during Phase 2. Pulmonary surfactant (PS) was protective factor of ROP in both two groups. GA in Phase 2 was significant lower than Phase 1 (P <0. 05), while duration of oxygen therapy, incidence of MV, PS and blood transfusion were higher in Phase 2 ( P < 0. 05) . Conclusions The incidence of ROP has increased. Reducing the incidence of preterm delivery, duration of oxygen therapy, incidence of MV and blood transfusion has important role in preventing ROP. Reducing the use of MV and the oxygen concentrations, appropriate PS therapy and focusing on early ophthalmic screening are important preventing severe ROP.

Objective To investigate the effect of fluvastatin on the expressions of caspase-12,CCAAT/enhancer-binding protein homologous protein(CHOP), and c-Jun N-terminal kinases (JNK) in ischemia-reperfusion brain injury in rats.Methods Forty two rats were randomly divided into sham operation group (6 rats), ischemia-reperfusion (I/R) group (18 rats), and fluvastatin (Flu) group (18 rats).The rats of I/R and Flu groups were molded by modified Longa intraluminal thread, then put to death at 2 h occlusion and 24 h reperfusion point.Expressions of caspase-12, CHOP, and JNK were detected with immunohistochemistry and Western blot.Results Immunohistochemistry and Western blot showed that the expressions of caspase-12, CHOP, and JNK were increased at 24 h reperfusion.Compared to I/R group, the expressions of caspase-12 and CHOP in Flu group were decreased significantly (all P ＜0.01);and the expression of JNK had no difference between I/R and Flu groups(P ＞ 0.05).Conclusions The increased expression of caspase-12, CHOP, and JNK showed that endoplasmic reticulum stress was involved in the pathological process of ischemia-reperfusion brain injury.Fluvastatin could inhibit the expression of caspase12 and CHOP, and could delete endoplasmic reticulum stress (ERS) in ischemia-reperfusion brain injury.

OBJECTIVE:To introduce the research progress of biliary tract prosthesis,to analyze the reason of complication following stent implantation,and to explore the biocompatibility of various biliary tracts and host. METHODS:We retrieved Medline database (1989/2009) and CNKI (1989/2009) using the computer. According to inclusion and exclusion criteria,the literatures were screened by the first author,and the data were collected,and the quality was evaluated. We described and arranged the treatment progress of biliary tract prosthesis implantation,complication of stent implantation and biocompatibility of biliary tract prosthesis to investigate treatment state,complication and biocompatibility of the biliary tract prosthesis. RESULTS:The literatures were summarized. The bilitary tract prosthesis contains plastic stent,mental stent,silica gel tract stent and degradable polylactic acid stent. The complications of stent implantation included transudation,hemorrhage,perforation and stenosis. Among various stents,the biocompatibility of plastic stent was poor,easy to be blocked,but the price was low,and easy to be taken out. The diameter of mental stent following distension could reach 7-10 mm,with long unobstructed time,but the price was higher compared with the plastic stent. The biocompatibility of silica gel tract stent was good. The silica gel tract had strong decay resistance and pliable texture,which could extend tumor excision range and elevate curative effects. Moreover,complications did not occur such as infection and stenosis of the biliary tract. Biocompatibility of nickel-titanium alloy biliary ducts was significantly better than the stent products,without complications. With the exception of price factor,the biocompatibility of degradable polylactic acid stent was the best,but further studies were needed to observe and study the formation of biliary sludge,stent displacement and blockage,stent degradation products. CONCLUSION:Biliary tract prosthesis implantation can be an important treatment method for stenosis of biliary tract. During treatment,enough preparation is needed prior to implantation according to various clinical symptoms to select suitable stent type. Indications are followed strictly to avoid the occurrence of complications. The biocompatibility of silica gel stent and Ni-Ti alloy stent is good,but the biocompatibility of other stents should be enhanced.

This composite might be one of cartilage scaffold materials for cartilage tissue engineering with potentially broad applicability.

AIM: To study the effect of high fat diet on the expression of sterol regulatory element biding protein-1 (SREBP-1) and transforming growth factor β_1 (TGF-β_1) in renal tubular cells and rosiglitazone intervention. METHODS: Wistar rats were treated with high fat diet and rosiglitazone for 3 months. The serum glucose, serum insulin and serum triglyceride were detected. Oil Red O staining was used to observe the renal lipid deposit and Masson staining was for the detection of ECM accumulation. SREBP-1, TGF-β_1 and FN protein were determined by the methods of immunohistochemistry and Western blotting. SREBP-1 mRNA was detected by in situ hybridization. RESULTS: Rosiglitazone prevented effectively the increase in serum glucose, serum insulin and serum triglyceride resulted from high fat diet. High fat diet led to lipid droplet formation in renal tubular cells and interstitial ECM accumulation, which was decreased by rosiglitazone treatment. Compared to normal rats, SREBP-1 protein and SREBP-1 mRNA showed high expressions in high fat diet rats that were lowered by rosiglitazone. The precursor segment and mature segment of SREBP-1 protein were decreased by 27.39% and 27.32%. Similarly, the high expressions of TGF-β_1 and FN protein in kidney of high fat diet rats were also prevented by rosiglitazone intervention. Compared to high fat diet rats, the expression of TGF-β_1 in rosiglitazone treatment rats was lowered by 19.14%. CONCLUSION: Rosiglitazone prevents effectively the over-expression of SREBP-1 and TGF-β_1 in renal tubular cells, and decreases lipid accumulation and ECM production in rats fed with high fat diet.
