Objective To investigate the correlation between atherosclerotic renal artery stenosis and hypertension.Methods One hundred and seventy-nine patients underwent renal artery angiography after coronary artery angiography. Results Among the 179 patients, 56.4% patients were detected as renal artery normal, 24% as renal artery disease, and 19.6% as renal artery stenosis. Compared with hypertensive patients with normal renal artery, ARAS patients had higher systolic blood pressure (148?23 mm?Hg vs 136?18 mm?Hg, P

Objective To assess the influence of host factors on the progression to cirrhosis in patients with chronic hepatitis C virus (HCV) infection. Methods Duration of 121 patients from HCV infection developing to liver cirrhosis was compared according to age at which HCV was infected, having the history of acute hepatopathy or not, infection pathway and sex. Patients with other hepatitis virus infection were excluded. Age, at which HCV was infected, was identified as that at blood transfusion or acute episode in non-transfusion patients. No patients had applied to any drugs. Results It took mean (27.17?6.78) years for the patients of age range 0-20 at which HCV was infected to develop to cirrhosis, while only (10.16?5.84) years for those of age range 41～50. There were significant differences between them (P0.05). Conclusion Our data show that patients with older age at which HCV was infected, with history of acute hepatopathy or HCV infection through blood transfusion developed into liver cirrhosis in shorter time. Sex was not found to have significant influence on the progression to cirrhosis.

0.05).At the eighth week of training and after ceasing the cognitive training for 4 weeks the NCSE scores and the FIM scores were improved in both groups,espeeially in the cognitive training group(P

Objective To determine the median effective dose ( ED50 ) of 0?5% ropivacaine for ul?trasound?guided adductor canal saphenous nerve block. Methods Twenty?three patients of both sexes, aged 18-45 yr, weighing 50-85 kg, of American Society of Anesthesiologists physical statusⅠ or Ⅱ, scheduled for elective arthroscopic meniscectomy, received an ultrasound?guided adductor canal saphenous nerve block. After successful location, 0?5% ropivacaine was injected. The sensory block of the area in?nervated by the saphenous nerve was assessed by pin?prick test. The dose of ropivacaine was determined by up?and?down technique. The initial dose of ropivacaine was set at 18 ml. Each time the dose increased∕de?creased in the next patient according to whether or not the sensory block of the area innervated by the saphe?nous nerve was complete, and the ratio between the two successive doses was 1 ∶ 1?2. The ED50 and 95%confidence interval of 0?5% ropivacaine for adductor canal saphenous nerve block were calculated by probit analysis. Results The ED50 (95% confidence interval) of 0?5% ropivacaine for ultrasound?guided adduc?tor canal saphenous nerve block was 10?7 ( 8?8-12?2) ml. Conclusion The ED50 of 0?5% ropivacaine for ultrasound?guided adductor canal saphenous nerve block is 10?7 ml.

Objective To investigate the complications and outcomes of the treatments in the early time of posterior chamber phakic in-traocular contact lens ( ICL) implantation for the treatment of high myopia, and to analyze the causes. Methods Forty-six patients ( 92 eyes) who underwent ICL/TICL implantations were enrolled in this study. The intraoperative and the postoperative complications in 6 months were observed,at the same time also the treatments and the outcomes were observed. Results None of the patients had a pupillary block. Only 8 eyes in all the patients had an elevated IOP after peripheral iridectomy ( PI) ,and 7 eyes after the ICL implantation,the highest IOP in which was 28 mmHg. No medication was given for treatment. In the YAG PI group,the incidence rate of iris bleeding and pigment dispersion were all higher than that in the YAG PI group (P<0. 05);2 crystalline lens of different patient were damaged intraoperation. Rotation of TICL was observed in 2 eyes. Only 2 individuals of all the patients in this study had complained visual disturbances,which was shadows and glare. Visual psychological change occurred in 1 patient. Conclusion The complications in the early time after ICL implantation for treat-ment of high myopia can prevent and control,the satisfaction of the patients is high.

Objective To assess the clinical outcomes about the visual qulitity of toric implantable contact lens ( TICL) implantation for high myopia with astigmatism. Methods Fifty-two eyes of 27 patients that underwent TICL implantation were examined. Uncorrected visual acuity( UCVA) ,best corrected visual acuity( BCVA) ,refraction,contrast sensitivity ( CS) with and without glare were evaluated before and after the treatment. Results Significant improvement in UCVA and BCVA were found at 1 month and 6 months after treatment (P<0. 05). The refraction at 1 month ( -0. 56 ± 0. 42)D and 6 months ( -0. 58 ± 0. 22)D after treatment were of no significant difference (P>0. 05), and the astigmatism at 1 month ( -0. 35 ± 0. 60)D and 6 months ( -0. 31 ± 0. 42)D after treatment were of no significant difference either (P>0. 05). The CS with and without glare were all significantly better than results before operation for 6. 0,12. 0 and 18. 0 cycles/degree (P<0. 05),but there were no significant difference between 1 month and 6 months after treatment (P>0. 05). No significant difference were found preoperatively,1 month after treatment and 6 months after treatment in terms of CS with and without glare (P>0. 05). The satisfaction of this investigation was 100%. Conclusion The TICL performed well in correcting high myopia with astigmatism,and it is a good surgical option for the treatment.

Postoperative ileus( POI)is a temporary impairment of coordinated gastrointestinal motility that develops as a consequence of abdominal or non-abdominal surgery and is a major factor contributing to the prolonged hospitalization of patient. In recent years,because of the widespread use of opioid analgesics,morphine induced POI is common. This article reviewed the progress in study on mechanism and management of POI caused by morphine.

A new, convenient, and rapid method for kinetic measurement of human fibrinolysis was established. The alteration of absorbance (A) in the process of blood coagulation and lyses was automatically scanned and recorded using a UV2000 spectrophotometer connected to a computer. The parameters of human fibrinolysis kinetics were established. Urokinase at 20 U/mL was the optimal concentration used. There was significant difference in fibrinolysis kinetics and plasma plasminogen concentration between 22 normal subjects and 27 patients with acute myeloblastic leukemia (P<0.05 and <0.01 respectively). The coefficience of variation was (5.24+/-1.51)%. This method could also be used to measure the plasma fibrinogen concentration at the same time. It was concluded that this method was stable and was capable of providing dynamic, direct experimental data and multiparemeters for clinicians. It was also valuable in evaluating the anti-and pro-fibrinolytic capcity of patients' plasmas, allowing for monitoring of therapy, choice of drugs and adjustment of drug concentrations.

An actinomycete B37 was isolated from an intertidal marine sponge Hymeniacidon perleve, which has strong activity against Gram positive bacteria and moderate activity against tumor cells. The mycelium and spore morphology, physiological properties and 16SrDNA sequence suggested that B37 is Streptomyces pseudogriseolus. The fermentation conditions of this strain were investigated for the biosynthesis of bioactive metabolites.

ObjectiveTo investigate the effort of MHA-bBMP implantation combined with limited contacted titanium net duct fixation on femoral shaft bone defect of rabbit.Methods48 rabbits were divided into the experimental group (treated with bionic bone MHA-bBMP plus titanium net duck) and control group (treated with iliac autograft plus titanium net duct) with 24 animals in each group. The rabbit femoral shaft bone defect model was established by cutting 10 mm bone fragment off. After operation, bionic bone MHA-bBMP/iliac autograft was implanted into bone defect area and fixed with limited contacted titanium net duck. The general condition, serum alkaline phosphatase, X-ray, histopathologic examination and electron microscope were performed.ResultsThe fixation stability of titanium net duck in two groups was good. The bone defect of two groups was repaired. The results of phosphatase, X-ray, histopathologic examination and electron microscope of two groups were not significantly different.ConclusionBionic bone MHA-bBMP is a high bioactivity substitute, and can obtain therapeutic effect equal to iliac autograft when repairing rabbit's femoral shaft defect.
