Objective To evaluate the angiographic effectiveness of stenting for non-protected left main coronary leisions. Methods The follow-up angiograms of 18 patients who had received stent implantation for non-protected left main disease during 1997-2004 were assessed. Results (1) There were totally 9 patients implanted with two stents in distal left main bifurcation lesion. Among the 6 patients who had implanted two drug eluting stents using V technique, 4 of them had ostial restenosis of the branches and had TLR. Another 2 patients with bare metal stents implanted using T-stest technique also experienced restenosis and had TLR. (2) In the 9 patients with single stent implanted, 5 patients implanted the stents crossing-over the LCX and only 1 of them had restenosis. Among the 3 patients who had received left main body stenting, one patient had diffuse restenosis and performed TLR. Conclusion (1) Implantation of 2 stents in distal left main lesion showed a high restenosis rate. On the other hand, crossing over the LCX can be applied safely in left main bifurcation lesions and show a better prognosis.

Forty patients with hypertension suspected to stenosis of renal artery were selected from Department of Cardiology, General Hospital of Chinese PLA between June 2007 and March 2008, including 28 males and 12 females with an average age of (60.0?15.6). Capoten test and renal artery angioplasty were performed in all patients to detect brain natriuretic peptide changes before and after the Capoten test and renal artery stent implantation. Among 40 patients underwent Capoten test, 30 showed positive result and 10 negative. The levels of brain natriuretic peptide before and after Capoten test in patients with positive result were statistically different (P 0.05). Among thirty patients with positive Capoten test undergoing renal artery angioplasty, twenty-three patients underwent stent implantation, and their brain natriuretic peptide showed statistical differences between before and after stent implantation (P 0.05). The results of the study show that levels of brain natriuretic peptide can be used to evaluate possible effect of stent implantation for patients with hypertension suspected to stenosis of renal artery.

To observe the germistatic and germicidal effects of origanum volatile oil (OVI) on the dysentery bacteria, the abdominal cavity of mice was infected with Shigella sonne (Sh. sonnei) and Shigella flexneri (Sh. flexneri) F2a. After OVI was given to the mice via gastric lavage, the effects of OVI on the infected mice were observed. The minimal inhibitory concentration (MIC) and minimal bactericidal concentration (MBC) for dysentery bacteria were determined in vitro. The results showed that origanum volatile oil showed obvious protective effect on mice infected with Sh. sonnei and Sh. flexneri F2a and it had germistatic and germicidal effects on dysentry bacteria. We are led to conclude that origanum volatile oil is an effective medicine against the infection of dysentery bacteria.

BACKGROUND: Following trauma caused by seawater, cells often exhibit special pathological changes because of the special physico-chemical properties of seawater.OBJECTIVE: To observe corneal histopathological changes and interleukin-6 level in aqueous humor of a rabbit model of penetrating corneal trauma combined with seawater immersion.METHODS: The rabbit eye models of penetrating corneal trauma caused by firecrackers were established in 16 adult healthy grey rabbits. A 3-mm whole-layer incision was made in the cornea. The right eyes served as experimental sides and the left eyes served as controls. Seawater was injected into the aqueous humor of the right eyes via the corneal incision. The eye surface was flushed with seawater for 30 minutes. Physiological saline was used for the left eyes. RESULTS AND CONCLUSION: Optical microscopy results showed that at 1, 2, 3 days after model establishment, corneal cells on the experimental side exhibited severe necrosis and abscission, obvious swelling of substantia propria layer complicated by cellular infiltration. At 1 and 2 days after model establishment, the pathological changes on the control side were the same as the experimental side, but they were mild, but at 3 and 5 days, they were obviously alleviated. At 1, 2, 3 days after model establishment, interleukin-6 level in aqueous humor was significantly higher on the experimental side than on the control side (P < 0.05). These findings suggest that the degree of injury on the experimental side was more severe than that on the control side, indicating that seawater may be an important causative factor of corneal injury.

Objective To study the correlation between the post-transplant renal allograft function and the variation of serum cystatin C (CyC) concentration in renal allograft recipients. Methods One hundred and ninety-three renal allograft recipients accepted the same combination immunosuppressive regimen of tacrolimus, mycophenolate and prednisone were enrolled into the study. Patient's serum and urine samples were collected on day 5 post-transplant to detect serum cystatin C, serum and urine creatinine (SCr). Correlation analysis was used to analyze correlation between CyC concentration and SCr concentration or the calculated creatinine clearance rate (CkCCr) by using the Cockcroft-Gault equation and urine creatinine clearance rate (CCr). Specificity and sensitivity of using the CyC concentration to evaluate glomerular filtration rate (GFR) were calculated as well.Results The mean concentrations of serum CyC and SCr on day 5 post-transplant were (1.91±1.2)mg/L and (174.0±129.1)μmol/L, respectively. While the CCr and CkCCr were (67.9±27.3)ml/min and (68.1±27.8)ml/min, respectively. Forty-two patients had a CyC concentration below 1.25 mg/L, 102 patients'CyC concentrations were between 1.25 and 2.0 mg/L and 49 patients'CyC concentrations were above 2. 0 mg/L. As for SCr, 62 patients had a concentration below 125 μmol/L, 83 patients'concentrations were between 125 and 200 μmol/L and 48 patients'concentrations were above 200 μmol/L. For CkCCr, there were 52 cases with a concentration above 80 ml/min, 96 cases with a concentration between 80 and 60 ml/min and 45 cases with a concentration below 60 ml/min. Serum CyC concentration had a negative correlation with CkCCr (r=-0. 907, P＜0. 001) and had a significantly positive correlation with SCr concentration (r=0. 886, P＜0. 001). SCr had a significantly negative relationship with CkCCr (r=-0. 889 ,P＜0. 001). Serum CyC had higher correlation with CkCCr than the correlation between SCr and CkCCr. The ROC curves showed that areas under curve of CyC, SCr, CCr and CkCCr were 0. 877, 0. 771, 0. 832 and 0. 909, respectively. Specificity and sensitivity of CyC, SCr,CCr and CkCCr were 69.3%, 96.1%, 77.1%, 71.3%and 91.6%, 52.2%, 67.5%, 84.6%, respectively.Conclusions Serum CyC concentration elevates earlier than SCr concentration when there is slight renal function impairment. Serum CyC concentration might become a more sensitive marker to evaluate the post-transplant renal allograft function in renal transplant recipients.
