AlM:To explore the clinical outcome of trabeculectomy with mitomycin C ( MMC) on glaucoma.
METHODS: A total of 57 patients (95 eyes) of primary glaucoma were randomly divided into two groups, 31 patients ( 54 eyes ) in trabeculectomy with MMC ( T+MMC ) group, which received trabeculectomy with 0. 2mg/mL MMC in surgical sites, and 26 patients ( 41 eyes ) in trabeculectomy ( T ) group. The anterior chamber, bleb, intraocular pressure ( lOP ) and complications were observed. The post-operative follow-up periods ranged between 4 and 6mo.
RESULTS:The mean lOP was 11. 24 ± 3. 73mmHg on 1d in group T+MMC. There was the significant difference compared with preoperative lOP ( P<0. 01 ), while no difference with the group T (P>0. 05). At final follow-up, the lOP was significantly different between group T+MMC and group T (16. 15±3. 62mmHg vs 18. 79±5. 27mmHg, P<0. 05). The rate of bleb formation was 94. 44% and 80. 48%in group T+MMC and T, respectively (P<0. 01). The postoperative complications were seldom, hyphema and corneal edema, and were cured finally.
CONCLUSlON:Trabeculectomy with MMC for glaucoma can effectively reduce postoperative scar formation of the filtration passage and lower the lOP to a target level with fewer complications.

Objective The recurrence and metastasis of malignant tumor could affect the survival of patients. Early detection of cancer cells in peripheral blood and effective therapy promptly are of clinical importance. The present study was to investigate the carcinoembryonic antigen (CEA) mRNA expression and serum CEA level in blood from patients with colorectal cancer and to evaluate its clinical significance. Methods Peripheral blood samples were collected from 35 eligible patients with colorectal cancer and 9 post operative patients. CEA mRNA was detected by reverse transcriptase polymerase chain reaction (RT PCR) and serum CEA was detected by time resolved fluorometric methods. Results The positive rate of CEA mRNA in blood samples of 35 patients with colorectal cancer was 45.7%, and 2.7% in healthy volunteers. Two of the nine post operative patients (22.2%) showed CEA mRNA positive. The positive rate increases with the pathological staging and showed no significant relation with the malignant extent of cell differentiation. Serum CEA mRNA positive rates in patients with CEA positivity (72.2%) were significantly higher than those in patients with negative CEA mRNA expression (42.3%).Conclusion The expression of CEA mRNA in peripheral blood cells correlates with the pathological staging of colorectal cancer and it could be of potential use to monitor the micrometastases of tumor. Long term follow up is needed to evaluate its clinical significance.

Objective To observe the in vitro anti-Coxsackievirus B3m (CVB3m) effect of sophocarpine(SC) extracted from Sophora flavescens, a traditional Chinese herb. Methods HeLa cells were cultured and the micro-dose cytopathic effect (CPE) assays were applied to detect the toxicity of SC. CPE-inhibitory assays were used to observe the in vitro anti-CVB3m effect of SC. MTT and crystal assays were introduced to examine the anti-CVB3m effect of SC. HeLa cells were infected with CVB3m and added with SC in different concentrations 15 h later.The viability and number of survival of HeLa cells were determined by MTT and crystal violet assays, respectively. Results No toxicity was found on HeLa cells by SC with concentrations 100 ?g/mL, SC could accelerate and aggravate the CPE. SC could protect the CVB3m-infected HeLa cells with concentrations from 1.56 to 25 ?g/mL, and the viability and cell number measured by MTT and crystal violet assay in the SC-handled cells were higher and bigger than those in the virus infected ones. However, the inhibitory effect of virus was exacerbated with higher concentrations (50 and 100 ?g/mL), and the cell number and viability of the SC-handled cells were smaller and lower than those of the infected ones. Conclusion SC with a proper concentration has the in vitro anti-CVB3m effect and may protect HeLa cells from CVB3m infection.

MicroRNAs(miRNAs)are a class of small RNA molecules which play a pivotal role in the regulation of genes involved in diverse processes.Recently,many viral-encoded miRNAs have been discovered,which suggests that viruses also use this fundamental mode of gene regulation.Although the functions of most viral- encoded miRNAs are unknown,some of them are involved in evading CTL,mediating latent infection,apoptosis suppression,etc.Uncovering the role of viral miRNAs in the pathopoiesis offers an immense opportunity not only to develope effective antiviral therapies,but also to identifying novel molecular targets for developing antiviral reagents.Therefore,recent progress on vmiRNAs was reviewed.

MicroRNAs (miRNAs) are a newly identified class of non-protein-coding small RNAs that play important roles in multiple biological processes. Recent evidence indicates that the expression of many miRNAs is both temporally and spatially regulated by RNA editing, differential processing and tissue-specific enhancers, and the potential for ultimately designing molecular medicines based on the modulation of miRNAs seems good. A better understanding of the mechanism which regulates miRNAs is very helpful to reveal the pathogenesis of some diseases, discover novel molecular targets for treatment by interference, and develop an effective gene therapy. Therefore, the latest progress in the mechanism regulating miRNAs is summarized.

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.
