Prostate cancer is one of the common malignant tumors of the urinary system and mostly found in elderly men. Like most tumors, prostate cancer involves a variety of molecules in its occurrence and progression. More studies on the development of prostate cancer focus on the tumor markers, DNA damage repair related genes, and tumor invasion and metastasis related factors. This article presents an overview on the research progress in these three aspects.

ObjectiveTo evaluate the value of application of spiral CT with 3D reconstructure on diagnosis and treatment of tibial plateau fractures.Methods15 cases of tibial fractures treated with x-ray and 16-slices spiral CT,3 D images were made,fractures were classified and evaluated with 3D images and treated with correct treatment.ResultsAll of the 15 patients got correct diagnosis by 16-slices spiral CT with 3D reconstructure,1 failed by x-ray.10 fractures were operated under 3D reconstructure guide and operation proved fractures revealed by 3D reconstructure finally.ConclusionSpiral CT with 3D reconstructure could offer more accurate location and classification of tibial plateau fractures,and it had obvious advantage on demonstration of spatial relationship,and it also could provide better planning and management for the tibial plateau fractures.

Objective To explore the prevalence of ETS gene fusion in prostate cancer and its correlation with patient's clinicopathologic index.Methods Ninety-one samples from prostate needle biopsy cases with median age 75 (55-90) years and 18 samples from radical prostatectomy cases with median age 72 (63-81) years were collected from Oct.2010 to Feb.2012.TMPRSS2-ERG,TMPRSS2-ETV1 and TMPRSS2-ETV4 fusions were tested by multi-probe fluorescence in situ hybridization (FISH) assay.Fusion positive and negative cases were compared with age,TNM stage,Gleason score (median Gleason score 7 (6-9)),and PSA value (median PSA 33.4 μg/L,mcan PSA 118.8 μg/L).In needle biopsy cases,there were early stage 32 (34％),locally advanced prostate cancer 36 (40％),metastasis 23 (26％) ; in radical prostatectomy cases,there were 9 cases in T2 stage,8 cases in T3 stage,1 cases in T4a stage,respectively.Results TMPRSS2-ERG fusions were present in 14.3％ (13/91,95％ confidence interval,0.071-0.215)biopsy specimens and in 11.1％ (2/18,95％ confidence interval,0-0.256) radical prostatectomy specimens.No TMPRSS2-ETV1 or TMPRSS2-ETV4 fusions were found in any cases.Altogether,13 (86.7％)cases possessed deletion pattern.And 7 (46.6％) hold insertion pattern.5 cases had both deletion and insertion pattern.38.5％ (5/13) deletion pattern had distant metastasis.Except one metastatic case harbored both deletion and insertion pattern,there was no insertion pattern accompanied with metastasis.There were no differences between fusion positive and negative cases in the distribution of age (P =1.000),PSA (P =1.138),primary Gleason score (P=2.186),Gleason score (P=2.107),TNM stage (P=2.052) and Risk Degree (P=2.597).Conclusions The TMPRSS2-ERG fusion positive cases harbor more deletion pattern than insertion pattern.There are no differences between fusion positive and negative cases in the distribution of age,PSA,Gleason score,TNM stage and Risk Degree.

Objective To evaluate the efficacy and safety of the endovascular interventional minimally invasive techniques(IMIT)for treatment of carotid artery iniury. Methods A total of 111 cases of carotid artery injury diagnosed by digital subtraction angiography(DSA)were treated with IMIT.Except for 1 case of extracranial segment injury of internal carotid artery treated with transcatheter stentgraft placement to obturate the rupture of carotid artery,the other 110 cases of intracranial segment injury of internal carotid artery(ICA)were treated with embolization with balloons in 73,embolization with coils in 12,injection of NBCA and PVA in 6,stent-graft placement in 11 and embolization with multiple materials in 8. Results Angiography demonstrated rupture of extracranial segment of internal carotid artery and arteriovenous fistula(AVF)at the neck in 1 case,traumatic carotid cavernous fistula(TCCF)in 83.traumatic pseudoaneurysm at intracranial segment of carotid artery in 14 and both TCCF and pseudoaneurysm in 13.The interventional treatment succeeded in all cases and interual carotid arteries were well protected in 62 cases.Completion angiography documented complete obliteration of the fistulas,with complete disappearance of the clinical symptoms in 110 cases and improvement in 1.Minor complications occurred in 2 cases,without death occurred.During the follow-up for 1-14 months,16 cases reexamined with DSA,which showed that the symptoms of 3 cases reoccurred,2 of whom were cured by re-embolization and 1 was under clinical observation. Conclusions IMIT including transcatheter selective embolization and stent-graft implantation is minimally invasive,safe and effective for treatment of carotid artery injury.

0.05).Some waves(N2,P3,N3) were even absent in children with TS and mental retardation.Statistical analysis indicated that the differences were significant(all P0.05).Conclusion The functional deficit in TS was localized prominently in cerebral cortex and subcortex,and the changes of SEP were almost same marked on both sides.

Corneal endothelial cell(CEC)is the most critical part for the cornea, of which activity can influence the postoperative vision.It is very important for the clinical cornea preservation considering the function and its self-purification of donor cornea.There are a variety of classical methods, which can significantly prolong the saving time of donor cornea with its good quality of CEC.We reviewed the published papers about present preservation methods of cornea, which can give us many suggestions for the clinical cornea preservation.

In order to establish a method for the determination of the sterols of the oil in the freeze-dried acai (Euterpe oleracea Mart.) and to evaluate its antioxidant activities, a saponification/extraction procedure and high performance liquid chromatography (HPLC) analysis method were developed and validated for the analysis of phytosterols in PEE (Petroleum ether extract). Separation was achieved on a Purosper STAR LP C18 column with a binary, gradient solvent system of acetonitrile and isopropanol. Evaporative light scattering detection (ELSD) was used to quantify β-sitosterol and the total sterols. Peak identification was verified by retention times and spikes with external standards. Standard curves were constructed (r = 0.999 2) to allow for sample quantification. Recovery of the saponification and extraction was demonstrated via analysis of spiked samples. The highest content of total sterols is β-sitosterol. The antioxidant activities of the extracts were evaluated using the total oxyradical scavenging capacity assay (TOSC assay). The result showed that the PEE exhibited significant antioxidant properties, sample concentration and the antioxidant capacity had a certain relevance.

OBJECTIVETo study the blood enriching effects of Paeoniae Radix Rubra and Paeoniae Radix Alba, paeoniflorin and albiflorin on mouse model of blood deficiency caused by γ-ray radiation.

METHODBuild mouse model of blood deficiency induced by γ-ray radiation. Paeoniae Radix Rubra and Paeoniae Radix Alba were given during modeling. The amount of WBC was detected af- ter the treatment. Based on the result of WBC and paeoniflorin content, albiflorin content in Paeoniae Radix Rubra and Paeoniae Radix Alba, the same model and the same method were used to comparatively study the effect of blood enriching of paeoniflorin and albiflorin.

RESULTOn the 7th day, the amount of WBC in model mice treated with 2 g x kg(-1) Paeoniae Radix Alba and 2 g x kg(-1) Paeoniae Radix Rubra significantly increased compared with that of model group (P < 0.05). In another experiment with the same model, the amount of WBC in model mice treated with 120 mg x kg(-1) paeoflorin and 120 mg x kg(-1) albiflorin significantly increased (P < 0.05) compared with that of model group on the 7th day. On the 10th day, the amount of WBC in rats treated with 120 mg x kg(-1) paeoflorin increased significantly (P < 0.05) compared with that of model group. Compared with the same dose of paeoniflorin, the amount of WBC in mice treated with albiflorin had no significant difference.

CONCLUSIONAll Paeoniae Radix Alba, Paeoniae Radix Rubra, paeoniflorin and al- biflorin can raise the amount of WBC and have the effect of enriching blood induced by radiation, while paeoniflorin and albiflorin have a similar result in this model. The result indicated that both paeoniflorin and albiflorin are effective constituents in Paeoniae Radix Alba, and paeoniflorin work as the common effective constituent in both Paeoniae Radix Rubra and Paeoniae Radix Alba.
