Accuracy and clinical application of a REF-XT01 uric acid meter / 中华内分泌代谢杂志

Objective:This study aimed to evaluate the accuracy of a portable REF-XT01 uric acid meter in measuring blood uric acid concentration, and to determine whether the results of the uric acid meter could be used to guide the adjustment of uric acid-lowering drugs.Methods:1 551 subjects were enrolled from the Gout Clinical Medical Center of the Affiliated Hospital of Qingdao University. The fasting venous blood was collected and the serum uric acid was measured by an automatic biochemical analyzer. Meanwhile, the capillary blood uric acid was measured by fingertip puncture using the REF-XT01 uric acid meter. Linear regression, intra-group correlation coefficient(ICC), and Bland-Altman plots were used to analyze the uric acid concentration correlation between the biochemical analyzer(sUA BA)and the uric acid meter(sUA UM). The receiver operating characteristic curve(ROC curve)was conducted to evaluate whether sUA UM can be used as a reference for the gout patients to take uric acid-lowering drugs. Results:The regression analysis showed correlation between sUA BA and sUA UM, with the regression formula Y=0.875X+ 39.525( r=0.84, P<0.01)and the ICC was 0.829(95% CI 0.814-0.844, P<0.01). The Bland-Altman diagram showed a good consistence(the absolute deviation was-143.4-114.5 μmol/L, mean deviation was -14.4 μmol/L)between sUA BA and sUA UM. The sensitivity was 96.61%, specificity was 48.81%, and the area under the ROC curve(AUC)was 0.926( P<0.01)when 300 μmol/L was defined as the detection threshold of the uric acid meter, the sensitivity was 90.98%, specificity was 66.78%, and the area under the ROC curve(AUC)was 0.914( P<0.01)when 360 μmol/L was defined as the detection threshold of the uric acid meter. Conclusion:REF-XT01 uric acid meter is applicable for the adjustment of uric acid-lowering drugs for the gout patients, because of its high accuracy for the detection of uric acid.

Effects of intraoperative expansion on expression of stenosis-related genes in saphenous vein graft / 局解手术学杂志

Objective To investigate the effect of high pressure distention on the expression of stenosis-related genes of saphenous vein graft(SVG) during the coronary artery bypass grafting(CABG).Methods The biopsy specimens of saphenous vein collected from 10 patients who have undergone CABG,were divided into expansion group and no-expansion group.Real-time PCR and immunohistochemical staining were performed for examination of mRNA and protein expression of VE-cad,Egr-1,VCAN respectively.Student's t and Chi-square test were used to do statistic analysis.Results The results of RT-PCR showed that the mRNA transcription of Egr-1,VCAN in the expansion group were statistically significantly higher than those in no-expansion group(P<0.05).The mRNA transcription VE-cad in expansion group was statistically significantly lower than that in the no-expansion group(P<0.05).The immunohistochemical staining results showed that the expression of Egr-1 and VCAN in expansion group were significantly stronger than those in no-expansion group,while the expression of VE-cad was significantly lower than no-expansion group.Conclusion The intraoperative expansion of SVG can increase the expression of stenosis-related genes Egr-1 and Versican,and decrease the expression of stenosis-related gene VE-cad,which may be related with the SVG stenosis after CABG.

Should the lower end of the spinal cord be localized by MRI in all patients having low backache prior to spinal anesthesia?

This study investigates the position of the lower end of the spinal cord conus in Chinese adults with low backache using MRI, to locate the safe puncture site for spinal anesthesia. Eight hundreds adults suffering from low backache were included in the study. Magnetic resonance imaging was used to localize the lower end of the spinal cord conus. Adult females' conus positions were slightly lower than the males [median: L1:lower, quartile: L1:middle-L1:upper for females; median: L1:lower, quartile: L1:upper-L2 for males; P < 0.001]. In addition our data showed that in 23.25% of patients the tip of the conus was located at the upper 1/3 level of L3. Pearson's correlation analysis showed that when the study population was divided by age group [Group A = 30 years of age; Group B = 30-60 years old; Group C = more than 60 years of age], cone position was significantly lower in older patients [r= 0.113, P < 0.05]. Spinal puncture should not be performed higher than the L3-L4 intervertebral space in Chinese patients having low backache unless the position of the lower end of the spinal cord is identified by prior MRI

Objective To investigate the effect of norepinephrine infusion at 0.03-0.3 μg·kg-1 ·min-1 on renal function in patients undergoing kidney transplantation. Methods Thirty-two ASA Ⅲ or Ⅳ patients aged 22-64 yr weighing 44-88 kg undergoing kidney transplantation were studied. Dialysis was performed within 36 h before operation. Blood pressure was fairly stable. Combined spinal-epidural anesthesia (CSEA) was performed. Spinal anesthesia was performed at L2,3 interspace and hyperbaric 0.5% bupivacaine 10-15 mg was injected into the subarachnoid space. The upper level of sensory block measured by pin-prick reached T6. Epidural catheter was placed at T11,12 interspace and 1% ropivacaine was given intermittently. The patients were randomly allocated into preoperative baseline level (increase or decrease amplitude ＜ 10% of baseline level) by dopamine or norepinephrine infusion during operation. Venous blood samples and urine samples were obtained at the end of operation and 12 h after operation for determination of serum concentrations of cystatin C and β2-microglobulin and urine α1- and β2-microglobulin concentrations. Urine was collected and the volume was recorded. Meanwhile the consumption of furosemide administration during the 12 h after operation was recorded. Results The two groups were comparable with respect to age, M/F sex ratio, body weight, the volume of urine and fluid infused, and the consumption of furosemide. There was no significant difference in serum cystatin C and β2-microgiobulin and urine α1- and β2-microglobulin concentratious, urine volume and consumption of furosemide administration between the transplantation without adverse effect on kidney allograft function.

The position of conus medullaris in Chinese adult population / 中华麻醉学杂志

Objective To investigate the variation in the position of conus medullaris in Chinese adult population in order to avoid hitting conus during spinal puncture. Methods Eight hundred patients suffering from back pain, aged 18-91 yr, were enrolled in this study. The position of conus medullaris was determined using Siemens 1.5 T magnetic resonance imaging system. According to the method described by Reimann, the vertebral body was used as mark of reference to the level of the end of conus. Results There were 190 patients in whom the position of the end of conus medullaris was lower than L1,2 . The incidence of the position of the end of conus medullaris lower than L1,2 was higher in patients 30-60 or older than in those under 30, and in those over the age of 60 than in those 30-60 (P ＜ 0.05). Conclusion Spinal puncture should be performed cautiously at L2,3. CT or MRI is recommended before operation for the patients to locate the position of conus medullaris and avoid injury to the spinal cord.
