Objective To investigate the effects of c?myc promoter binding protein 1(MBP?1)gene on the proliferation of human Saos?2 osteo?sarcoma cells in vitro. Methods Saos?2 cells were divided into three groups:blank control group(untransfected cells),negative group(cells transfected with missense sequence)and experimental group(cells transfected with MBP?1 shRNA). Two MBP?1 shRNA sequences and one neg?ative control shRNA sequence were designed ,synthesized and cloned into pSIREN?retroQ plasma. Then the recombinant plasmids were construct?ed and transfected into human Saos?2 osteosarcoma cells by Lipofectamine 2000. The expressions of MBP?1 mRNA and protein in Saos?2 cells were detected by real?time PCR and Western blot ,respectively. The effects of altered expression of MBP?1 on cell proliferation were measured by CCK?8 cell proliferation assay. The expressions of cyclin D1 and cyclin E in Saos?2 were determined by Western blot. Results PCR and sequenc?ing results indicated that the recombinant plasmids pSIREN?retroQ was constructed. The relative expression level of MBP?1 mRNA in the MBP?1 siRNA transfection group was significantly decreased than that in blank control group(P<0.05). Compared with the blank control group,the ex?pression levels of MBP?1 protein in the experimental group also significantly decreased. The proliferation abilities of Saos?2 cells at 48,72,and 96 hours after MBP?1 siRNA transfection were significantly increased than those in the blank control group(P<0.05). Compared with the blank con?trol group,the expression levels of cyclin D1 and cyclin E protein in the experimental group also significantly increased(P<0.05). Conclusion Knockdown of the expression of MBP?1 gene promotes the proliferation of human Saos?2 osteosarcoma cells. MBP?1 gene may become the new tar?get of gene therapy for osteosarcoma.

Objective To evaluate premature clopidogrel cessation,intraoperative tranexamic acid and their interaction on bleeding and transfusion outcomes in on-pump CABG patients.Methods The current study is a prospective and randomized trial with 2 × 2 factorial design.The first factor is preoperative clopidogrel with 2 levels,clopidogrel ingestion within 7 days preoperatively (group E) and nave to clopidogrel (group B).The second level is antifibrinolytic therapy with 2 level,tranexamic acid (group T) and placebo (group P).A total of 333 patients receiving selective on-pump CABG were recruited.The tranexamic acid regimen was a bolus of 10 mg · kg-1 followed by a maintenance of 10 mg · kg 1 · h-1 throughout the surgery.Results Baseline characteristics were fairly balanced among the groups.Tranexamic acid significantly reduced postoperative blood loss.major bleeding,the volume of erythrocyte and plasma transfused,the exposure of erythrocyte,plasma and any allogeneic products (ET vs EP,P ＜ 0.01 ; BT vs BP,P ＜ 0.01).Clopidogrel within 7 days preoperatively significantly increased blood loss (EP vs BP,P＜0.05),major bleeding,the volume of erythrocyte (EP vs BP,P＜0.01) and the exposure of erythrocyte and plasma (EP vs BP,P ＜ 0.05) and any allogeneic products (EP vs BP,P ＜ 0.01).Under the protection of tranexamic acid,the bleeding and transfusion outcomes were comparable between the patients with premature clopidogrel cessation and those nave to clopidogrel (ET vs BP,P ＞0.05).Perioperative mortality,morbidity and the incidence of adverse events were comparable among the groups except for IABP.Conclusion Comparing with nave to clopidogrel,premature cessation within 7 days preoperatively deteriorated bleeding and transfusion outcomes in on-pump CABG patients.Intraoperative tianexamie acid could reduce the risk.

BACKGROUND:Orthotopic liver transplantation is the most effective therapy for the treatment of end-stage liver diseases, but the lack of donor source, immune rejection, and repeated infections limit its application. Stem celltransplantation technology provides a new idea for the treatment of end-stage liver diseases. A variety of methods have been confirmed to successful y induce umbilical cord blood mesenchymal stem cells converted into liver cells in vitro.
OBJECTIVE:To explore the clinical efficacy and feasibility of human umbilical cord blood mononuclear cells transplantation in the treatment of decompensated cirrhosis.
METHODS:Twenty-three patients with decompensated cirrhosis received al ogeneic human umbilical cord blood mononuclear celltransplantation. Serum alanine aminotransferase, albumin, cholinesterase, total bilirubin and prothrombin time were detected at post-transplantation weeks 2, 4, 8 and 24. Improvement in clinical signs and symptoms as wel as adverse reactions was observed.
RESULTS AND CONCLUSION:Liver function had no changes at 2 weeks after human umbilical cord blood mononuclear celltransplantation (P>0.05). At 4 weeks after celltransplantation, serum alanine aminotransferase was improved significantly (P<0.05), but the other indexes stil had no changes. Until 12 weeks after celltransplantation, there were significant improvements in al the liver function indicators (P<0.05) and the liver stiffness (P<0.05). By the end of 24 weeks, al the test results were improved significantly (P<0.01). Clinical symptoms were al eviated, including fatigue improvement in 20 cases (87%), improved appetite in 21 cases (91%), and relieved ascites in 19 cases (83%). No severe adverse reactions were found during the transplantation and 24-week fol ow-up. These findings suggest that human umbilical cord blood mononuclear cells transplantation is effective and safe for the treatment of decompensated cirrhosis, which can be considered as a clinical therapy for patients with advanced cirrhosis.

Objective To investigate the diagnosis and surgical management of ureteral obstruction after renal transplantation.Method A respective study was performed on 15 cases of ureteral obstruction who received renal allografts.All of the cases were confirmed,including 5 cases of stenosis of ureterovesical junction,4 cases of stenosis of distal ureter,2 cases of blood clot blockage,2 cases of edema due to perforation of distal ureter,1 case of ureteral calculi,and 1 case of extrinsic compression of hematoma.All 14 patients underwent open surgical management to reestablish ureter with D-J catheter as stent for 12-16 weeks.One patient was subjected to percutaneous nephrostomy followed by percutaneous ureteroscopy,the obstructed site was identified at ureterovesical junction and antegrade balloon dilation and D-J stent in ureter were performed subsequently.Result Fifteen patients were diagnosed as ureteral obstruction by colour Doppler ultrasound and MRU.All of the patients were resolved the obstructions after surgical managements and the renal function got improved.No reobstruction occured during one year follow-up period.Conclusion Colour Doppler ultrasound and MRU can definitely be used to diagnose ureteral obstruction after renal transplantation.Early diagnosis and surgical management are very important.Open surgical management of the obstructed ureter is an effective method.Antigrade balloon dilation is a therapeutic approach to treat ureteral obstruction.

OBJECTIVETo determine the distribution of aortic arch and intra/extracranial cerebral arterial atherosclerosis in Chinese patients who had suffered acute ischemic strokes.

METHODSEighty-nine patients with acute ischemic strokes were included in this study. Transesophageal echocardiography (TEE) was used to evaluate potential sources of embolisms in the aortic arch and in the heart; duplex ultrasound was used for the carotid artery; and intracranial Doppler (TCD) imaging was used for the middle cerebral artery (MCA), anterior cerebral artery (ACA), posterior cerebral artery (PCA), and basilar artery (BA). An atherosclerotic lesion in the aortic arch was defined as normal (0); mild plaque (1); moderate plaque (2); and protruding plaque or mobile plaque (3). A lesion in the carotid artery was considered a plaque if the maximal carotid plaque thickness was 1.2 mm. TCD results were deemed abnormal if flow velocity was either greater or lower than normal, and, in the case of the MCA, if an asymmetry index above 21% was measured.

RESULTSOf the 89 patients, 52 (58.43%) patients showed evidence of aortic arch atherosclerosis (AAA), including 11 (12.36%) patients graded mild, 18 (20.22%) patients graded moderate, and 23 (25.84%) patients graded severe. Of the 23 patients with severe AAA, AAA was determined to be an important potential embolic source in 14 patients. Forty-nine (50.56%) patients had carotid arterial plaques (CAPs). The incidence of carotid plaques was higher among patients with AAA than among patients without AAA (71.15% vs 21.62%, OR = 3.291, 95% CI = 1.740 - 6.225, P < 0.001). TCD abnormalities affecting the MCA were found in 54 (60.67%) patients. Differences in incidence of TCD abnormalities between patients with AAA and without AAA (69.23% vs 48.65%) were not significant (OR = 1.423, 95% CI = 0.976 - 2.076, P = 0.05). There was a higher incidence of AAA in older, male patients with a history of diabetes and smoking.

CONCLUSIONSAAA is an important potential source of cerebral embolic strokes. The presence of carotid arterial plaques correlates with AAA incidence. Most of carotid artery lesion were plaques other than severe stenosis, it may be the character of carotid atherosclerosis of stroke patients. It appears that atherosclerosis does not mainly occur in the intracranial arteries in stroke patients as thought before. Aged, male, diabetes, and smoking are important risk factors to the AAA.

In order to study the relationship between serum C-reactive protein (CRP) levels, leukocyte count and carotid plaque in patients with ischemic stroke, carotid duplex examination was performed by high-definition imaging (HDI) 5000 triplex system. Serum CRP was measured by nephelometry within 72 h after index ischemic stroke. A lesion was considered a plaque in the presence of a maximum intimal-medial wall thickness (IMT) 1.2 mm. Results of carotid ultrasonography were divided into two groups: M1, normal (IMT < 1.2 mm) and M2, abnormal (IMT > or = 1.2 mm). The results showed that the mean age of M2 was significantly older than that of M1 (69.7 +/- 10.4 versus 62.5 +/- 9.6, P = 0.001). The patients with hypertension and diabetes mellitus (78%, 35% respectively) in M2 were significantly more than those (52%, 18% respectively) in M1 (P < 0.01, P < 0.05). There were 32 (65%) patients with elevated CRP levels in M2, but 33 (46%) patients with elevated CRP levels in M1, with the difference being significant between the two groups (P < 0.05). The levels of serum glucose and leukocyte count (8.1 +/- 5.5, 10.3 +/- 4.0, respectively) in abnormal CRP group were significantly higher than that of normal CRP group (6.4 +/- 2.8, 8.7 +/- 3.4) (P < 0.05, P < 0.05); elevated CRP levels was found in 42 (62%) patients with territory infarction and 23 (43%) patients with lacunar infarction respectively, with the difference being significant between these two groups (P < 0.05). It was concluded that the elevation of CRP levels was an significant clinical index for carotid plaque in patients with acute cerebral infarction.
