AIM:To investigate the effect of bone morphogenetic proteins 9 (BMP9) on the migration and in-vasion abilities of human lung squamous-cell carcinoma NCI-H520 cells and its mechanism.METHODS:The expression of BMP9 at mRNA and protein levels in the NCI-H520 cells and human bronchial epithelial ( HBE) cells was detected by RT-PCR and Western blot.The NCI-H520 cells were transfected with the recombinant adenovirus AdBMP9 and the expres-sion of BMP9 at mRNA and protein levels was validated by RT-PCR and Western blot.The migration and invasion abilities of the NCI-H520 cells were determined by wound-healing and Transwell assays.The mRNA and protein levels of the migra-tion-related factor matrix metalloproteinase 2 (MMP2) were detected by RT-PCR and Western blot.The level of phospho-rylated Smad1/5 (p-Smad1/5) was detected by Western blot.Meanwhile, NCI-H520 cells were treated with BMP specific antagonist AdNoggin and AdBMP9.The level of p-Smad1/5 and the cell migration ability were measured by Western blot, wound-healing and Transwell assays.RESULTS:The expression of BMP9 at mRNA and protein levels was lower in NCI-H520 cells than that in HBE cells.After AdBMP9 was stably transfected into the NCI-H520 cells, the expression of BMP9 at mRNA and protein levels was significantly up-regulated, cell migration and invasion abilities were significantly de-creased, and the mRNA and protein levels of MMP2 were decreased.Meanwhile, the level of p-Smad1/5 was increased. Noggin reversed BMP9-caused the increase in p-Smad1/5 and the decrease in cell migration ability.CONCLUSION:O-ver-expression of BMP9 inhibits the migration and invasion abilities of lung squamous-cell carcinoma NCI-H520 cells.The activation of BMP-Smad signaling pathway may be involved in this inhibitory process.

Purpose To study the clinicopathological and immunohistochemical features, carcinogenesis and differential diagnosis of female pelvic serous carcinoma. Methods The clinical data, macroscopic and microscopic features and immunostaining results of 20 patients with pelvic serous carcinoma were studied, and some associated literatures were reviewed. Results 20 cases of PSC aged from 23 to 87, with the mean age being 58. 9. PSC may occur in fallopian tube, ovary and peritoneum, while they were referred to hospital because of abdominal distention, abdominal pain or pelvic mass. The tumor often invasive pelvic organs diffusely when they were diag-nosed, so, the primary site were difficultly determined. Usually, the primary focus of serous carcinoma of fallopian tube is small and easily planted in pelvic. The patients with ovarian serous carcinoma or peritoneal serous carcinoma had serous tubal intraepithelial car-cinoma at the mean time. Conclusions The tubal epithelial cells may be the major source of PSC. About the specimen of PSC, we need check the fallopian tube carefully to determine the primary site, and make differential diagnosis with peritoneal malignant mesothe-lioma and metastatic carcinoma from other sites than pelvic when it diffusely invasive peritoneum.

Objective To compare safety and feasibility using radial versus femoral access during cardiac catheterization of patients who had previously undergone coronary artery bypass graft ( CABG) surgery. Methods We retrospectively evaluated 116 consecutive patients who underwent graft intervention via the transradial (TRA group, n = 46) or transfemoral approach (TFA group, n = 70), and observed the baseline clinical characteristics, angiography characteristics and complications between the 2 groups. Results The baseline clinical characteristics between the 2 groups were similar ( all P > 0. 05) . No significant difference was observed in angiography characteristics and procedural parameters including operation time, radiation exposure and puncture time between the 2 groups (all P > 0. 05). There was no significant difference in major adverse cardiac events during hospitalization. PCI to graft vessels were all successful and procedural success rates were similar between the 2 groups (P = 0. 669). Vascular access site complications were significantly lower ( P = 0. 03) in the TRA group. No access site complication was recorded in the TRA group. 7 cases (10. 0% ) with complications were recorded in the TFA group including 1 case of major bleeding (1. 4% ), 3 cases of minor bleeding (4. 3% ), 2 cases of local hematorna (2. 9% ) and 1 case of A-V fistula formation. Conclusions In contrast to the transfemoral route, the rate of major vascular complications was negligible using the transradial approach.

ObjectiveToinvestigatetheprotectiveeffectandmechanismofscutelarincombinedwith paeoniflorin after permanent cerebral ischemia in rats. Methods Forty-eight adult male SD rats w ere randomly divided into four groups: sham-operation, cerebral ischemia, scutelarin+ paeoniflorin, and cyclopamine (n=12 in each group). A model of permanent middle cerebral artery occlusion w as induced by suture method. The intraperitoneal injection of cyclopamine 6 mg/kg, a specific inhibitor of sonic hedgehog (SHH) pathw ay, at 15 min before ischemia in the cyclopamine group, w hile other groups w ere intraperitoneal y injected an equal volume of saline. At 0 hour and 3 hours after ischemia, the scutel arin+paeoniflorin group and cyclopamine group w ere intraperitoneal y injected scutel arin ( 20 mg/kg ) and paeoniflorin (30 mg/kg), while other groups were intraperitonealy injected an equal volume of saline. Neurological deficit scores w ere performed at 24 hours after ischemia, and then the rats w ere decapitated. The cerebral infarct volume w as measured by using 2,3,5-triphenyltetrazolium chloride (TTC) staining. Real-time fluorescent quantitative polymerase chain reaction and Western blotting w ere used respectively to detect the expression levels of SHH, Patched-1, Gli-1 mRNAs and proteins in the ischemic cortex. Results The neurological deficit scores in the cerebral ischemia group, scutel arin+paeoniflorin group, and cyclopamine group w ere 3.33 ±0.52, 1.50 ±0.55, and 3.67 ±0.52, respectively. The neurological deficit score in the scutel arin+paeoniflorin group w as significantly low er than that in the cerebral ischemia group ( P<0.05), and the neurological deficit score in the cyclopamine group w as significantly higher than that in the scutelarin+paeoniflorin group ( P<0.05). The infarct volume percentage in the cerebral ischemia group, scutelarin+paeoniflorin group, and cyclopamine group were 31.77%±1.19%, 22.94%±2.65%, and 35.53%±0.20%, respectively. The infarct volume in the scutel arin+paeoniflorin group w as significantly less than that in the cerebral ischemia group ( P<0.05), and the infarct volume in the cyclopamine group was significantly larger than that of the scutelarin+paeoniflorin group (P<0.05). The expression levels of SHH, Patched-1, Gli-1 mRNAs and proteins in the cerebral ischemia group, scutelarin+paeoniflorin group, and cyclopamine group w ere significantly higher than those in the sham -operation group (al P<0.05). The expression levels of SHH, Patched-1, Gli-1 mRNAs and proteins in the scutelarin+paeoniflorin group were significantly higher than those in the in the cerebral ischemia group (al P<0.05), and the expression levels of Gli-1 mRNA and protein in the cyclopamine group were significantly lower than those in the scutelarin+paeoniflorin group ( al P<0.05 ). Conclusions The scutel arin combined w ith paeoniflorin has certain protective effect on focal cerebral ischemia injury in rats. Its mechanism is associated w ith the activation of SHH signaling pathw ay.
