Endovascular repair has gained worldwide popularity for the treatment of aortic dissection and aortic aneurysm.The non-tapered stents are selected usually.The aortic diameters vary in different level.High incidence of distal stent-induced complications is closely related to the aortic taper angle.According to several published studies,the aortic taper angle could be evaluated by establishing geometric model.Applications of tapered stents can significantly reducing the incidence of distal stent-induced comnplications.This review summaries the latest researches in the studies of the progress and the application of the aortic taper angle and the tapered stents,providing a reference for endovascular stent-graft selecting in the treatment of aortic dissection and aortic aneurysm.

BACKGROUND: The inflammatory reaction occurs following implantation of cardiovascular stent with manifestations of the activation of blood coagulation system and dramatically increasing of inflammatory markers serum C-reactive protein. OBJECTIVE: To explore the changes of inflammatory reaction and C-reactive protein in coronary artery disease patients following cardiovascular stent implantation.METHODS: A computer-based online search of CNKI (1990/2009) and PubMed databases (1990/2009) was performed for related articles with the key words "cardiovascular stent, C-reactive protein" in Chinese and "cardiovascular stent on plasma, C-reactive protein" in English.RESULTS AND CONCLUSION: Based on the metal stents, drug-eluting stents can transfer the active drugs to the damaged vessels, release them into the vascular wall and inhibit the in-stent restenosis, Main drugs of anti-inflammatory drug-eluting stent include dexamethasone and methylprednisolone. Main drugs of anti-migratory and anti-proliferative drug-eluting stent includerapamycin, paclitaxel and actinomycin D. Main drugs of supporting intima concrescence stent include estradiol. Coronary artery stents implantation can induce and aggravate local inflammation reaction, which have important infection for vascular endodermis hyperplasia and restenosis occurrence. Some impressible index for inflammation reaction, such as levels of C-reactive protein,have predictive value for vascular events following the coronary artery stents implantation. A significant increase in plasma C-reactive protein after coronary stenting has been observed following stent implantation. Therefore, understanding of inflammatory reaction and C-reactive protein, as well as cytokine changes is important for preventing restenosis, early treatment of restenosis, as well as improving treatment effect.

Objective To investigate the crosstalk between Wnt signaling pathway and TGF-? signaling pathway in prostate cancer cell line PC-3. Methods Luciferase report assay and RT-PCR methods were used to explore the crosstalk between two pathways. Results Wnt signaling pathway activated TGF-? responsive CAGA-luciferase reporter activity. ?-catenin(WT), TCF-4(WT), GSK3? (KM) activated while TCF-4(DN) inhibited CAGA reporter activity. ?-catenin(WT), TCF-4(WT) synergized to activate TGF-? signaling while TCF-4(DN) had converse effect.TGF-? signaling pathway activated LEF-1 luciferase activity through a Smad3-dependent manner.Smad7 activated LEF-1 luciferase activity,Smad3 and Smad4 also synergically activated LEF-1 reporter activity.?-catenin(WT),TCF-4(WT) cooperated with each other to the activity of cyclinD1 promoter luciferase while Smad3 inhibited cyclinD1 promoter activity.The inhibitory effect of Smad3 on cyclinD1 promoter could be partially reversed by co-transfecting ?-catenin(WT),TCF-4(WT).TGF-? induced the expression of VEGF in PC-3 cells and this effect was enchanced by LiCl addition. Conclusions Wnt signaling pathway and TGF-? signaling pathway can activate each other in prostate cancer cell line PC-3.Two pathways have crosstalk and this might be important for the development and progression of prostate carcinoma.

· AlM: To explore the correlation of center retinal thickness and axial length in non-proliferative diabetic retinopathy ( DR) .
· METHODS:A total of 80 cases ( 155 eyes ) of non-proliferative DR patients were divided into three groups according to the axial length, 22~24mm of 27 cases (51 eyes) were normal group, 24 ~26mm of 28 cases ( 55 eyes) were long axis group, >26mm of 25 cases ( 49 eyes) were super long axis group.The center retinal thickness and ocular axial length of three groups were measured and the correlation of center retinal thickness and axial length were analyzed.
· RESULTS:Among the inner ring and outer ring, the center retinal thickness of upper and lower, bitamporal and nasal side of super long axis group was thicker than that in normal group, with statistically significant difference ( P<0.05 ); Among the inner ring and outer ring, the center retinal thickness of upper and lower, bitamporal and nasal side of super long axis group was thicker than that in long axis group, with statistically significant difference ( P<0.05); The DR central macular of retinal thickness was no correlation of the axial length ( P >0.05 ), but retinal thickness get thinning with increased of axial length on the inner ring and outer ring area, showed a negative correlation ( rinner ring =-0.63, router ring=-0.67, P<0.05).
·CONCLUSlON:Center retinal thickness and ocular axial length in non -proliferative DR patients, and center retinal thickness of super long axis patients are thinning obviously.

Objective To compare the therapeutic effect of endovascular repair (EVAR) and open surgical repair(OSR) of abdominal aortic aneurysm in high-risk patients. Methods The clinical data of 55 patients from 1998 to 2008 with infrarenal abdominal aortic aneurysm who received surgical treatment were analyzed by using the customized probability index. The perioperative and short term advantages and disadvantages of OSR group (n=20) were compared with EVAR group (n=35). Results All patients in OSR group were followed up, 94% patients in EVAR group were followed up, the mean follow up time were 75 and 70 months respectively. (1) Compared to OSR group, the EVAR group had shorter operation time [(3.1±0.6) h vs (4.9±0.9) h, P<0.05], (2) EVAR group had shorter ICU and hospital stay after operation and less blood loss (P<0.01), (3) Compared to OSR group, the EVAR group had lower mortality within 30 d(2.86% vs 15%), (4)the EVAR group had lower peri-operative complications(17% vs 40%), (5) The main complications of EVAR were endoleak (8.57%), (6) The main complications of OSR was cadiovascular incidence(25%). Conclusions Endovascular treatment, indicated for AAA in high-risk patients, can cut down the perioperative incidence of cadiovascular events, mortality and complications. CPI is useful to estimate the perioperative incidence of cadiovascular events, mortality and complications, and can be used to guide the therapeutic method.

OBJECTIVE:To investigate the characteristics of serious ADR in psychiatric hospital,and to provide reference for effective and safe use of drugs in the clinic. METHODS:114 cases of serious ADR in our hospital from 2004 to 2015 were ana-lyzed retrospectively in terms of general information,primary disease,route of administration,dosage form,drug types,organs or systems involved in ADR and clinical manifestations,top 5 ADR-inducing drugs and main clinical manifestations,etc. RESULTS:Of 114 serious ADR cases,the number of female was more than that of male(71/43). Patients aged 21-30 years old took up the greatest proprotion(35 cases,30.70%). The main involved primary disease was schizophrenia(54 cases,47.37%). Oral adminis-tration-induced ADR was most common(103 cases,90.35%). The main involved drugs were antipsychotics,occupying the great-est proportion(75 cases,65.79%). Digestive system involved was the most common(53 cases,42.74%), Olanzapine tablets had the highest incidence of serious ADR (23 cases,18.55%),the main clinical manifestation were both abnormal liver function. There were 8 cases of new serious ADR (7.02%). Most of the ADR can be cured after drug withdrawal or countermeasures,no death case was found. CONCLUSIONS:Psychiatric drugs can induce serious ADR as treat psychiatric disease,among which the in-cidence of ADR induced by Olanzapine tablets is the highest and mainly manifestes digestive system symptoms. It is suggested to strengthen serious ADR monitoring to promote the safe use of drugs.
