E2F transcription factor 1 (E2F1) is a major member of the E2F transcription factor family and participates in a wide range of physiological regulatory processes, such as cell cycle, survival, apoptosis, and metabolism. It is proved that the activity of E2F1 is related to the G1/S phase regulation of the cell cycle dependent on tumor suppressor retinoblastoma protein (RB). Recent studies have shown that E2F1 is highly expressed in prostate cancer cells, manifested as an oncogene, and its expression level is closely related to the occurrence, development, and poor clinical prognosis of prostate cancer. Androgen receptor (AR) is the main driving factor for the growth and progression of prostate cancer, and the changes of AR pathway play a key role in the pathological progression of prostate cancer. This article provide a systematic and comprehensive summary on recently published articles to review the role of the E2F1 pathway in prostate cancer.

OBJECTIVETo investigate the expression of long non-coding RNA-HOTAIR in prostate cancer cells and its effects on the growth and metastasis of the cells.
METHODSUsing quantitative reverse-transcription PCR (qRT-PCR), we determined the relative expression of HOTAIR in the normal human prostate epithelial cell line RWPE-I and prostate cancer cell lines PC-3 and DU145. We detected the effects of HOTAIR on the cell cycle and invasiveness of prostate cancer cells by RNA interference, flow cytometry, and Transwell mitration assay.
RESULTSThe expressions of HOTAIR in the PC3 and DU145 cells were increased 3.2 and 5.7 times, respectively, as compared with that in the normal RWPE-1 cells. After si-HOTAIR interference, the prostate cancer cells were arrested in the G2 phase and downregulated in the G1 phase. The invasive ability of the prostate cancer cells was evidently inhibited, with the inhibition rates of 32% and 44% of the PC3 cells and 43% and 34% of the DU145 cells for si-HOTAIR1 and si-HOTAIR2, respectively.
CONCLUSIONIncRNA HOTAIR is highly expressed in prostate cancer, which is associated with the growth and invasiveness of prostate cancer cells. HOTAIR is potentially a novel marker for the diagnosis and prognosis of prostate cancer.

Objective: After establishing standard multi-modal therapy, prognosis of refractory and metastatic high-grade osteosarcoma remains dismal and unchanged over the last decades. Early clinical intervention to newly detected metastatic lesions is crucial and effective for better prognosis. Arsenic trioxide (ATO) is one of the oldest remedies used in traditional oriental medicine and is recently rediscovered as an immunomodulator due to its activity against other solid tumors. This study aims to evaluate the efficiency of ATO combined with first-line chemotherapy in treating pulmonary metastatic osteosarcoma patients with long-term follow-up in our institution.Methods: Osteosarcoma patients with pulmonary metastasis were intravenously administered with ATO (5-10 mg) daily combined with first-line chemotherapy for their treatment. A total of 119 patients were finally enrolled; 65 presented metastasis, and 54 relapsed with lung metastasis. Results: Two-year and five-year overall survival (OS) rates for these patients reached 52.6% and 30.9%, respectively. Only 20 cases underwent thoracotomies (16.8%). Our five-year OS was nearly similar to that of other institutions (37% in Rizzoli, Italy). We observed that combined with bone metastasis, bilateral metastasis, and >3 pulmonary nodules, incomplete resection of pulmonary lesions deteriorated the disease and significantly influenced survival as compared with all other parameters. Conclusion:Combined with conventional chemotherapy, ATO may be effective and well-tolerated as new therapeutic option for patients with nonresectable pulmonary metastatic osteosarcoma. Lung metastasectomy should be strictly selected only for populations who benefit from this treatment.

AlM: To investigate the relationship between the anterior ischemic optic neuropathy ( AlON ) and the carotid artery change using doppler ultrasound.METHODS:Fifty-four cases of AlON patients and 54 cases of healthy control were observed, atherosclerotic spots were detected by the application of color ultrasound.RESULTS:ln AlON group of 54 patients, 38 cases appeared carotid atherosclerosis, accounting for 70%. The number of cases with hard plaque, soft plaque and mixed plaques were 18, 13, and 7 respectively, accounting for 33%, 24% and 13%. ln the control group, 20 cases were detected atherosclerotic change, accounting for 37%. And the number of cases with hard plaque, soft plaque and mixed plaques were 12, 5 and 3 respectively, accounting for 22%, 9%, 6%. Significant stenosis and velocity change were showed in neither AlON group nor control group. Compared with the control group, AlON group had more cases of atherosclerotic plaque, the difference was statistically significant (χ2=12. 836, P=0. 005)CONCLUSlON: The incidence of AlON is correlated with carotid atherosclerosis, and carotid ultrasonography is significantly valuable for AlON etiology and diagnosis.

AIM: To observe the effect of Ahmed glaucoma valve implantation intravitreal bevacizumab in the treatment of neovascular glaucoma ( NVG) .
METHODS:Twenty-two cases (22 eyes) who presented with NVG were first treated with intravitreal bevacizumab 0. 1mL ( 2. 5mg ), then with Ahmed glaucoma valve implantation after regression of iris neovessels. Cases were followed - up for 6 - 36 ( mean 24 ) mo with observation on visual acuity, IOP control, regression of iris neovessels, and complications during or after surgery.
RESULTS: Iris neovessels was regressed in different degree after injection within 1wk in 22 eyes. At final follow-up, the IOP of 18 eyes were all less than 21mmHg without any drugs and of 3 eyes with 1-3 kinds of anti-glaucoma drugs after combined Ahmed glaucoma valve implantation. The IOP of one eye was controlled after cryotherapy. The mean IOP dropped from 45. 36 ±8.13mmHg preoperatively to 15. 59 ± 3. 21mmHg postoperatively. IOP reduction was statistically significance between preoperative and postoperative ( P<0. 05) at final follow-up. Visual acuity was improved in 9 eyes (41%) and was no changed in 13 eyes. No serious complications were observed during or after intravitreous bevacizumab injection and Ahmed glaucoma valve implantation.
CONCLUSION: Ahmed glaucoma valve implantation and intravitreal bevacizumab in the treatment of NVG is useful and safe. It improves the success rate of surgery and preserves visual function, furthermore its complications are less.

OBJECTIVETo develop a new technique for assessing the risk of birth defects, which are a major cause of infant mortality and disability in many parts of the world.
METHODSThe region of interest in this study was Heshun County, the county in China with the highest rate of neural tube defects (NTDs). A hybrid particle swarm optimization/ant colony optimization (PSO/ACO) algorithm was used to quantify the probability of NTDs occurring at villages with no births. The hybrid PSO/ACO algorithm is a form of artificial intelligence adapted for hierarchical classification. It is a powerful technique for modeling complex problems involving impacts of causes.
RESULTSThe algorithm was easy to apply, with the accuracy of the results being 69.5%±7.02% at the 95% confidence level.
CONCLUSIONThe proposed method is simple to apply, has acceptable fault tolerance, and greatly enhances the accuracy of calculations.

OBJECTIVETo determine the relationship between viral burden in urine and hearing loss in neonates with cytomegalovirus (CMV) infection.
METHODSTwenty-two neonates with CMV infection between April 2006 and January 2010 were enrolled. Their viral burden in urine and hearing loss information were studied. The receiver operating characteristic curve (ROC) was constructed and the cutoff was determined based on their medical information. The hearing levels were evaluated by brain stem auditory evoked potential (BAEP) during the age of 3 to 6 months in 20 patients.
RESULTSThe viral burden in urine in neonates with abnormal BAEP was higher than that in neonates with normal BAEP (5.06 ± 1.50 vs 3.73 ± 0.86, P<0.05). Hearing loss was predicted with a sensitivity of 0.545 and a specificity of 1.0 by using ROC at the cutoff point of 5.1 which were defined after logarithmic conversion at 1.27×10(5) copies/mL of CMV burden in urine. The incidence of hearing loss during the age of 3 to 6 months was strikingly higher in high viral burden group than that in low viral load group (P<0.05).
CONCLUSIONSThe viral burden in urine can predict the possibility of hearing loss in neonates with CMV infection. Hearing loss is likely to be developed when viral burden in urine ≥1.27×10(5) copies/mL in neonates with CMV infection.
