Objective To investigate effects of neural retina on development of the structure of outer blood retinal barrier in embryogenesis. Methods The retinal neural epithelium (RNE) and pigment epithelium (RPE) layers of 150, 120 and 90 embryonic chicken eyes incubated for 7, 10, and 14 days were peeled off. RNE was used to prepare the culture medium with different conditions (7drcSF3, 10drcSF3, 14drcSF3). RPE cells of 7- and 14-incubated chicken embryos were cultured on laminin-coated transwell filter. The SF3, 7drcSF3, 10drcSF3, 14drcSF3 medium were used respectively in the apical chamber and SF2 was used in basolateral chamber. After the formation of monolayer, the transepithelial electrical resistance of the RPE was detected. After the fixation of RPE cells, the condition of the tight junction among the cells was observed by immunohistochemistry and transmission electron microscopy. Results For the RPE cells of 7- and 14-day incubated embryonic eyes, the difference of TER in various medium of SF3/SF2, 7drcSF3/SF2, 10drcSF3/SF2, 14drcSF3/SF2 was statistically significant (P

ObjectiveTo investigate the imaging characteristics of solitary fibrous tumor(SFT).MethodsThis study included 11 cases with SFT proved by pathological results.The imaging manifestations were retrospectively reviewed and analyzed in comparison with surgical and pathological results. Among them,8 patients underwent CT plain scan (1/8) or enhanced scan (7/8),4 patients underwent MR plain scan (2/4) or enhanced scan (2/4),and only 1 patient underwent both CT and MR scan.Results( 1 )SFT were located in the thoracic cavity(2/11 ),abdominal and pelvis(5/11 ),and somatic soft tissues (4/11 ).The average tumor size was 11.8 cm ( 2.5 to 23.0 cm).Among them,4 tumors were round or ellipse,and 7 tumors were irregular.Eight tumors had well-defined contours,and the others showed illdefined contours.(2)On CT scan,all SFTs showed inhomogeneous density with low density areas.Calcification was seen in I case,and hemorrhagic foci were detected in 2 cases.(3)On MR scan,all SFTs showed intermediate signal intensity on T1 WI.Three tumors were slightly hyperintense and the other was hypointense on T2WI.All of them were rich of vascular signal voids.Three tumors,including 2 tumors with scattered long T1 and T2 signal and 1 tumor in the liver with hyperintense haemorrhage,displayed inhomogeneous mixed signal.One tumor in the orbit showed homogeneous signal.(4)On enhanced scan,9 tumors showed irregular enhancement with multiple circuitous vessels in the arterial phase,and continuous or progressive enhancement with patch non-enhanced areas in the venous phase.( 5 ) Histologically,SFTs were composed of juxtaposed hyper- and hypo-cellular spindle cells,dense collagenous stromas and numerous thin-walled blood vessels with a staghorn configuration.Conclusion The possibility of SFT should be considered when a single soft tissue mass with sharp border,inhomogeneous density is detected,especially with inhomogeneous enhancement maintaining in the venous phase.

AIM:To investigate the effects of bcl-3 gene on the migration and apoptosis of human colon cancer cell line RKO, and the changes of cyclin D1 and apoptosis-related proteins.METHODS:After silencing of bcl-3 gene expression in human colon cancer cell line RKO by lentiviral vector with RNA interference, the changes of RKO cell migration ability were investigated by wound healing assay.The changes of RKO cell apoptotic rate after bcl-3 gene silencing were detected by flow cytometry with Annexin V/PI staining.The protein expression of cyclin D1 and apoptosis-related proteins in the RKO cells after bcl-3 gene silencing was determined by Western blot.RESULTS:The wound healing rates of the RKO cells were 84.00% and 40.00% before and after bcl-3 gene silencing, respectively, with statistically significant difference (P<0.05).Annexin V/PI staining showed that the cell apoptotic rates were 12.89% and 59.67% before and after bcl-3 gene silencing, respectively, when RKO cells were treated with 5 μmol/L cisplatin for 24 h, with statistically significant difference (P<0.05).The expression of cyclin D1 decreased, while the expression of Bax increased after bcl-3 gene silencing (P<0.05).CONCLUSION:After bcl-3 gene silencing, the migration ability of RKO cells decreases, and the apoptotic rate increases, accompanying with the changes of cyclin D1 and Bax.bcl-3 gene can affect the apoptosis of RKO cells by changing the expression of cyclin D1 and Bax.

Objective To investigate the curative effect of benidipine hydrochloride on patients with coronary slow flow angina pectoris(CSFA).Methods Sixty cases patients with CSFA were randomly divided into two groups of 30 patients each.In the control group patients were received aspirin(100 mg,1 times/d) and atorvastatin(20 mg,1 times/d) as basic treatment;in the treatment group patients were received basic treatment plus benidipine hydrochloride(4 mg,1 times/d).Follow up for 6 mouths,the effectiveness rate of treatment(relief of angina and electrocardiogram of myocardial ischemia),the correction of thrombolysis in myocardial infarction(TIMI) frame count(CTFC) before and after the different intervention,and the incidence of adverse cardiovascular events were compared between the treatment group and the control group.Results The effectiveness rate of treatment in the treatment group(86.7%,26/30) was significantly higher than that in the control group(63.3%(19/30);χ2=4.356,P=0.037).There were significant reductions of CTFC in both groups after the different intervention(treatment group:(28.43±3.95) frames vs.(18.40±3.73) frames,t=10.254,P=0.000;control group:(27.87±4.14) frames vs.(21.87±4.17) frames,t=5.580,P=0.000).There was more significant reductions of CTFC in the treatment group as compared to the control group(t=2.138,P=0.037).The incidence of adverse cardiovascular events in the treatment group(10.0%(3/30)) was significantly lower than that in the control group(33.3%(10/30),P=0.028).Conclusion Benidipine hydrochloride is effective in the treatment of CSFA.

Objective To discuss how to practise and consummate to shoot and assess the portfilm for radiotherapy. Methods Double radiography technique was used to take a portfilm. The reference mark points (plumbum points) were added into the field at the first exposure and the cross lines drawn based on the plumbum point images were definited as the reference coordinate to the actual field. Then, the portfilm was compared and analyzed with the simulator planning film. Results The images of both plumbum points and block boundaries were distinct in the portfilm, but the resolution and contrast of the tissue structure image was inferior to the ordinary film from simulator. However, all different structures and positions could be identified in order to assess if the actual field coincided with the radiation planning. Conclusions Although the real-time property of the portfilm is inferior to the electric portal image device (EPID), the double radiography portfilm is feasible as an important quality control method in radiation therapy due to its lower price and easier performance. The design of reference points is the key point in this technique.

Objective To explore the effects of HMGCoA agents and ACE inhibitor on serum inflammatory markers in patients with acute coronary syndrome (ACS). Methods The 60 patients with ACS were randomly divided into two groups, one treated with lipid lowered by HMGCoA agents and the other treated with HMGCoA agents added with ACE inhibitor. After 4 months, serum levels of some inflammatory markers were measured by means of ELISA. Results Serum levels of certain inflammatory markers were significantly higher in the ACS group than in the control group and became significantly lower 4 months later in the follow-up group. There were no differences in all the inflammatory markers between the two groups receiving different therapies 4 months later. Conclusion Serum levels of some inflammatory markers may have certain diagnostic value for ACS and may reflect the stability of the disease. HMGCoA agents seem to have no effect on inflammatory responses in a short period.
