Background and purpose: Reports showed that berbefine not only had an effect ofdetoxification and inflammation but also could induce the cell to apoptosis. Berberine may also inhibit the migration and metastasis of tumor. To investigate the effects and mechanism of berberine on migration and metastasis of A549 cells, the proliferation, mobility and adhesion of A549 cells were observed after incubation with berberine. Methods: The proliferation was determined by MTT. Wound healing assay and adhesion test were used to observe the mobility and adhesion rate. The mRNA and protein expressions of MMP2 and MMP9 were assessed by semi-quantitive RT-PCR and gelatin zymography, respectively. Results: Berberine could significantly inhibit the proliferation ofA549 within a certain range of treating time and dose (P<0.05). The mRNA and protein expression of MMP2 and MMP9 gene were decreased slightly by the treatment ofberberine (P<0.05), especially at dose of 100 μg/ml. Conclusion: Berberine can inhibit the migration and adhesion abilities of A549 cells, probably by down-regulating the expression and activation of MMP2 and MMP9.

? AIM: To investigate the differences between synoptophore and triple prism strabismometry and its possible cause.?METHODS: There were 347 patients with horizontal concomitant strabismus involved, in which 76 patients were esotropia, 37 patients were male while 39 were female, with average age of 13. 27 ± 7. 77 years old. There were 271 patients with exotropia, 131 cases were male while 140 were female, with average age of 15. 43 ± 8. 42 years old. All the patients were examined by synoptophore and prism plus shaded strabismometry in a long distance of 6m. Datas were analyzed by SPSS 17. 0.?RESULTS:In the exotropia patients, the conversions of circular degree(°) and prism degree(△) were:1°=0. 29△ ~1. 78△, which was statistically significant with intermittent strabismus (P=0. 001). While in the esotropia patients, the conversions were:1°=2. 01△ ~2. 15△.?CONCLUSION: The diversity between the two methods is enlarged with the increase of squint angle for exotropia patients. While in esotropia patients, the diversity decreased with the increase of squint angle. Synoptophore equipped with +7. 00D, defects of the triple prism itself and proximal convergence during exam may be the reasons for the diversity.

Objective:To research the stability of Dazhu Hongjingtian injection combined with four different infusion solutions (0. 9% sodium chloride injection, 5% glucose injection, fructose injection, xylitol and sodium chloride injection) . Methods:The insolu-ble particles and pH value of Dazhu Hongjingtian injection in 0, 0. 5,1,2,4 and 8h after the combination were detected by the methods described in China Pharmacopeia ( 2010 edition ) . Results: Dazhu Hongjingtian injection combined with the four infusion solutions showed no significant changes in appearance and pH value in 8h. The number of insoluble particles in Dazhu Hongjingtian injection combined with 0. 9% sodium chloride injection and 5% glucose injection met the requirement in the pharmacopeia, and that in 0. 9%sodium chloride injection was lower than that in 5% glucose injection. The quantity of insoluble particles in Dazhu Hongjingtian injec-tion combined with fructose injection exceeded the standard level, and showed remarkable change in the fourth hour. The quantity of insoluble particles in xylitol and sodium chloride injection slightly exceeded the standard. Conclusion: Dazhu Hongjingtian injection can be mixed with 0. 9% sodium chloride injection and 5% glucose injection, and fructose injection and xylitol and sodium chloride in-jection are not suitable for the solvent of Dazhu Hongjingtian injection. Although there is no instruction indicating that 0. 9% sodium chloride injection can be used as the suitable solvent for Dazhu Hongjingtian injection, the results of the experiment can be reasonable reference for diabetes patients treated with Dazhu Hongjingtian injection.

OBJECTIVETo observe microvessel density(MVD), epithelial stromal vascular cuffing(VC) and expression of vascular endothelial growth factor(VEGF) in human cervical carcinomas and to clarify their significance in the invasion and metastasis of cervical carcinoma.
METHODSVEGF and CD34 were stained immunohistochemically (SP) in 57 cases of cervical carcinoma (30 cases of squamous cell carcinoma, 20 of adenocarcinoma 7 of glandular and squamous cell carcinoma), 29 cases of cervical intraepithelial neoplasia (CIN) and 16 cases of normal cervices, meanwhile, MVD and VC were also assayed.
RESULTSThere were significant differences among the above 5 groups for MVD P<0.01 . The VC pattern showed a significant difference between cervical carcinoma and CIN or control group P<0.01). The positive rates of VEGF in normal cervical epithelium, CIN, squamous cell carcinoma, adenocarcinoma, glandular and squamous cell carcinoma were 18.8% 3/16, 82.8% 24/29), 93.3% 28/30), 100% 20/20 and 7/7(100%), respectively. There were significant differences between these cervical lesion groups and the control group(P<0.001). The MVD showed significant differences between the positive pelvic node metastasis and negative pelvic node metastasis P<0.05). There was no significant correlation between the expression of VEGF and the tumor diameter, clinical stage, pathologic grade and pelvic node metastasis.
CONCLUSIONThe expression of VEGF may play an important role in the angiogenesis of cervical carcinoma. Degree of malignancy of cervical carcinoma has a close association with microvessel density.

Objective To investigate the clinical features of internal carotid steal syndrome. Methods The clinical manifestations, CT or MRI, digital subtraction angiography, and blood flow compensation in 6 patients with internal carotid steal syndrome were analyzed. Results Of the 6 patients, 2 had unilateral internal carotid artery stenosis, 4 had severe stenosis (in which 2 were on the left side, 1 was on the right side, and 1 was on both sides). The clinical manifestations of the patients with internal carotid steal syndrome were watershed infarction and transient ischemic attack. Four patients had posterior circulation ischemia and 2 had anterior circulation ischemia. Digital subtraction angiography demonstrated that collateral circulation was established in all the 6 patients. The anterior communicating artery, posterior communicating artery, and pial artery were the common compensatory vessels. Conclusions Internal carotid artery steal syndrome can be presented as anterior or posterior circulation ischemia, and the collateral circulation plays an important role in the compensation.
