Objective To investigate the characteristics and analyze the differences of choroidal neovascularization (CNV) image between exudative age-related macular degeneration (AMD) and central exudative chorioretinopathy (CEC) using optical coherence tomography (OCT). Methods Twenty-three eyes of 22 patients with exudative AMD and 20 eyes of 19 patients with CEC, which were diagnosed as CNV using fundus fluorescein angiograph (FFA) or indocyanine green angiograph (ICGA), were exami- ned by OCT. The size of CNV and the thickness of retinal neurosensory layer in foveola were measured by OCT software. Results On OCT image, CNV had three main types of morphological features including simple CNV, CNV with serous retinal neurosensory layer detachment and CNV with choroidoretinal exudation. Exudative AMD mainly showed CNV with choroidoretinal exudation (56.52%) and CEC showed simple CNV (90 0%). The thickness of retinal neurosensory layer in foveola of patients with exudative AMD was thicker than that of patients with CEC and the size of CNV of patients with exudative AMD was larger than that of patients with CEC. Negative correlation was found between retinal neurosensory layer thickness in foveola and vision in both groups (?=-0.521, P =0.001). Conclusions There were certain discrepancy in morphology and area involved of CNV between exudative AMD and CEC on OCT images.

Geographic distribution of Polyporus umbellatus was predicted by using distribution records. Based on 42 distribution records from 12 provinces and bioclimatic data (1950-2000), georaphic distribution of P. umbellatus was modeled using Maxent. The results showed thatthe Receiver Operating Characteristic (ROC) curve analysis method was used to assess the accuracy of MAXENT model and the area under ROC curve (AUC) value of MAXENT was 0. 960 which suggested that the result of assessment was dependable. The geographic distribution pattern of were divided into three distribution block based on distribution values of 0.5-0.8: small area of Heilongjiang, Jilin, Liaoning and Hebei province, the board area of Yunnan, Guizhou and Sichuan, the southeast area of Tibet and the most area of Shanxi and Shannxi, the southeast board area of Shannxi, Gansu and Ningxia. Jackknife Test showed that average precipitation in warm seasons had the greatest contribution to the distribution gain of P. umbellatus, followed by mean temperature of driest quarter and annual mean temperature. The object suggests the potential distribution areasof P. umbellatus which is useful for the habitat conservation and introduction of P. umbellatus.

MicroRNAs (miRNA) plays an important role in biological development and disease occurrence and development, and acts as a "main switch" in biology. Among patients of essential hypertension, around 1/3 would suffer left ventricular hypertrophy (LVH). Hence, essential hypertension becomes an independent risk factor for cardiovascular diseases. And miRNAs plays an important role in the occurrence and development of LVH. This paper reviewed the role of miRNA in regulating the stress signaling pathway, defined its impact on the occurrence of LVH, and further emphasized the opportunities and challenges of miRNA as a biomarker and therapeutic target.

Objective To investigate of the radiological manifestations in congenital cystic adenomatoid malformation (CCAM) of lung in adult and to improve the diagnostic accuracy of CCAM of lung in adult.Methods Five cases with pathologically proved CCAM of lung in adult were retrospectively analyzed.Chest X-ray was available in 5 cases and chest CT was performed in 2 cases.Results On plain chest radiography,thin wall air cystic lesions with air-fluid level were detected in 3 cases.Honeycomb like small cystic lesion was detected in 1 case.Multiple round cystic lesions were found in 1 case.CT scan of the chest demonstrated a round thin wall air cystic lesion in the lateral segment of right lung's middle lobe,and a thin wall air cystic lesion with the wall merged into the shadow of chest wall in the left apicoposterior segment in one case.Small cystic lesions just like honeycomb were found in bilateral basal segments of the inferior lobes,with a 0.8—1.0 cm sized round mass revealed in the right lung′s inferior lobe basal segment, and the mass was spiculated in another case.Conclusion The imaging signs of CCAM of lung in adult is cyst or cyst-solid and at the risk of developing carcinoma.

Four small GTPase genes which may be relative to sclerotial development were firstly cloned from medicinal fungus Polyporus umbellatus using rapid amplification of cDNA end PCR (RACE) method. The results showed that full-length cDNA of PuRhoA was 698 bp contained 585 bp ORF, which was predicted to encode a 194 amino acid protein with a molecular weight of 21.75 kD with an isoelectric point (pI) of 6.44; the full length cDNA of PuRhoA2 was 837 bp in length and encoded a 194 amino acid protein with a molecular weight of 21.75 kD and an isoelectric point (pI) of 6.33; the full length cDNA of Puypt1 was 896 bp in length and encoded a 204-aa protein with a molecular weight of 22.556 kD and an isoelectric point (pI) of 5.75; the full length cDNA of PuRas was 803 bp in length and encoded a 212-aa protein with a molecular weight of 23.821 kD and an isoelectric point (pI) of 5.2. There are fani acyl transferase enzyme catalytic site and myrcene-transferase enzyme catalytic site in PuRhoA1 while the PuRhoA2 only possess myrcene-transferase enzyme catalytic site. Puypt1 contains the Rab1-Ypt1 conserved domain of small GTPase family and PuRas contains the fani acyl transferase enzyme catalytic site. According to the phylogenetic analysis all these four small GTPase clustered with basidiomycete group. Quantitative real-time PCR analysis revealed that Puypt1, PuRas and PuRhoA1 transcripts were significantly higher in the beginning of sclerotial formation than that in the mycelia, whereas the transcripts levels of PuRhoA2 gene were particularly lower in sclerotia than that in mycelia, suggesting that these four genes might be involved in P umbellatus selerotial development.
