Purpose:To investigate the relationship between the expression of NF?B family proteins in ovarian cancer cell lines with chemotherapy resistance of ovarian cell lines. Methods:First, 13 ovarian cancer cell lines were cultured, and then protein was extracted separately from cytoplasm and nucleus. Using Western blotting and MTT chemosensitive testing, the relationship between the expression of NF?B family proteins in ovarian cancer cell lines with chemotherapy resistance of ovarian cell was observed.Results:It was found that the expression of positive rate of P65, P50 and IKB in cytoplasm was 76.9%, 81.8% and 84.6% respectively, and the significant positive expression of P65 and P50 was also found in the nucleus, with a rate of 15.3%, 45.5% respectively. In OV MZ 5 and OV MZ 2774, the expression of P65 was positive and their IC 50 reached a significant value. Conclusions:It was concluded that P50 and P65 affected the growth and development of ovarian cancer cells with the effect of P50 being more obvious. P65 had a close relationship with the chemotherapy resistance of ovarian cancer cells, and thus P65 could be expected to be a new marker in the observation of prognosis.

BACKGROUND:Endovascular embolization materials have been produced and used clinicaly, but new problems constantly occur in the clinical application and new demands are also developed for embolic materials. OBJECTIVE:To retrospectively analyze the advantages and disadvantages of various types of embolic materials and to investigate the relationship between application fields and selection of embolic materials, thereby providing a reference for clinical treatment. METHODS:CNKI and PubMed databases were retrieved for relevant literature, and then embolic materials were systemicaly reviewed based on relevant clinical application and basic research literature in the folowing aspects: embolism mechanisms, clinical applications, advantages and disadvantages of various embolic materials. In this review, the existing problems in the current study were pointed out, and the development direction of relevant research and clinical application were also prospected. RESULTS AND CONCLUSION:Embolic materials should have biodegradability and biocompatibility. Current embolic materials include absorbable gelatin sponge, Polyvinylalcohol embolic agent, micro-coils and liquid embolic materials. Gelatin embolic material has no antigenicity and good histocompatibility, as wel as has excelent compressibility and water re-expansibility. Polyvinylalcohol particles are a polymer material that is insoluble in water, has high expansion coefficient, mechanical embolization, non-alergenic reaction, no acute systemic toxicity, no intracutaneous irritation, and can be used safely and effectively. Adhesive liquid embolic material has no vascular toxicity and has been widely used. Endovascular embolization materials have been produced in succession, and meanwhile, new problems in clinical applications have been found and new demands for embolic materials have been put forward continuously. Thus, a variety of embolic materials have their own advantages and disadvantages, and none of embolic materials can be applied to al diseases. To select an appropriate embolic material is very important for safe and effective treatment.

Objective To observe the effect of liver acquired expression of apobec-1 on blood lipid metabolism, hepatic low density lipoprotein receptor (LDLR), and hepatic low density lipoprotein receptor related protein (LRP) in nephrotic syndrome(NS) rabbits and to explore the lipid-lowering effect and possible mechanism.Methods Thirty healthy ordinary level male new Zealand rabbits were randomly divided into 3 groups:sham operation group (n =10), N S group (n =10), and apobec-1 treatment group (n =10).Adaptive feeding was given for 1 week, then NS group and apobec-1 treatment group underwent left nephrectomy,and 1 week later,adriamycin (4 mg/kg) was used to construct the NS model by way of ear vein injection.In the 11th week after operation, apobec-1 recombinant adenovirus (1 × 1013 virus/kg) was injected through ear vein in apobec-1 treatment group.The 12th week after operation, all rabbits were sacrificed.Right kidney, liver, blood and 24 hour urine were collected.In 3 groups, 24 hour urinary protein (24UPr), albumin (Alb), blood urea nitrogen (BUN), creatinine (Cr), blood lipid were detected.Renal pathology was observed by means of HE staining.Expressions of liver LDLR, LRP were observed by using Western blot.Results (1) There were significant differences among the 3 groups in 24UPr (F =42.778, P =0.000), Alb (F =3.819, P =0.034), BUN (F =6.562, P =0.005), Cr (F =16.076, P =0.000), total cholesterol (TC) (F =17.531, P =0.000), total triglyceride (TG) (F =6.192, P =0.006), very low density lipoprotein (VLDL-C) (F =6.192, P =0.006), low density lipoprotein (LDL-C) (F =34.924, P =0.000) and apolipoprotein B100 (ApoB100) (F =5.180, P =0.012) and apolipoprotein B48 (ApoB48) (F =6.161, P =0.006).(2) Compared with the sham operation group, NS group showed that 24UPr, BUN, Cr, TC, TG, VLDL-C, LDL-C, ApoB100 increased, but Alb decreased, and there was statistical significance (all P ＜ 0.05).(3) Compared with NS group, apobec-1 treatment group showed that TC, TG, VLDL-C, LDL-C, ApoB 100, ApoB48 decreased, and there were statistical significances (all P ＜ 0.05).(4) Compared with the sham operation group, apobec-1 treatment group showed that 24UPr, BUN, Cr increased, but Alb, apolipoprotein B48 (ApoB48) decreased, there were statistical significances (all P ＜ 0.05).(5) There were significant differences of hepatic protein expression among the 3 groups in LRP (F =44.180, P =0.000), LDLR (F =63.141 ,P =0.000).Compared with the sham operation group and NS group, apobec-1 treatment group showed that the expression of LRP was up-regulated (P ＜ 0.01,0.05), while the expression of LDLR was down-regulated (all P ＜ 0.05).Conclusions When liver acquired expression of apobec-1 in NS, it could up-regulate LRP,accelerate the elimination of ApoB48-lipoproteins, and produce a certain lipid-lowering effect.

Objective To explore the effect of the liver acquired expression of apolipoprotein B editing catalytic polypeptide-1 (Apobec-1) on hyperlipidemia of renal disease. Methods Thirty healthy ordinary level male New Zealand rabbits were randomly divided into three groups: sham operation group, nephropathy group, and Apobec-1 treatment group (Each group has 10 rabbits). Adapt feeding for one week, nephropathy group and Apobec-1 treat-ment group underwent left nephrectomy, and one week later, adriamycin (4 mg / kg) was used to construct the ne-phropathy model by ear vein injection. The eleventh week after operation, apobec-1 recombinant adenovirus (1 × 1013 Virus/ kg) was injected by ear vein in apobec-1 treatment group. The twelfth week after operation, all rabbits were sacrificed. Right kidney, liver, blood and 24h urine were left. In three groups, 24 hour urinary protein (24UPr), albumin (Alb), blood urea nitrogen (BUN), creatinine (Cr), blood lipid were detected. Renal pa-thology was observed by HE staining. Expressions of liver apobec-1, apolipoprotein B48(ApoB48)were observed by Western blot. Results ① Compared with the sham operation group, nephropathy group showed that 24UPr, BUN, Cr, total cholesterol (TC), total triglyceride (TG), very low density lipoprotein (VLDL-C), low density lipoprotein (LDL-C), apolipoprotein B100 (ApoB100) were increased(P < 0. 05), but Alb was decreased(P <0. 05). ② Compared with the nephropathy group, Apobec-1 treatment group showed that TC, TG, VLDL-C, LDL-C, ApoB100, ApoB48 were decreased(P < 0. 05). ③ Compared with the sham operation group, Apobec-1 treat-ment group showed that 24UPr, BUN, Cr were increased( P < 0. 05), but Alb, ApoB48 were decreased( P <0. 05). ④ Compared with the sham operation group and nephropathy group, Apobec-1 treatment group showed that the expression of Apobec-1 and ApoB48 were up-regulated (P < 0. 01). Conclusion When liver aquires expres-sion of Apobec-1 in hyperlipidemia of renal disease, it can reconstruct ApoB mRNA, increase the synthesis of ApoB48-lipoprotein, and play a certain lipid-lowering effect.
