Objective:To explore the influence of infusion drop speed on the efficacy of tiopronin for injection combined with sol-vents in the treatment of abnormal liver function. Methods:Totally 74 patients were randomly divided into the observation group and the control group with 37 ones in each. The infusion drop speed was 60-65 drops per minute in the observation group, and that was 30-35 drops per minute in the control group, and the infusion time was controlled in 1h in the observation group and 2h in the control group. The clinical effect and the improvement of liver function were compared between the two groups after a treatment course of 4 weeks. Results:The total effective rate of the observation group(83. 78%) was obviously higher than that in the control group(56. 76%) (P<0. 05) after the treatment, and ALT, AST and TBIL of liver function indices were improved obviously except for ALB in the two group, and the difference was statistically significant between the two groups(P<0. 05). Conclusion:Tiopronin for injection can effectively improve the clinical effect by strictly controlling the time and drop speed of infusion.

Hyperglycemia has been identified as one of the important factors involved in the microvascular complications of diabetes, and has been related to increased cardiovascular mortality. Endothelial damage and dysfunction result from diabetes; therefore, the aim of this study was to determine the response of endothelial cells to stressful stimuli, modelled in normal and high glucose concentrations in vitro. Eahy 926 endothelial cells were cultured in 5 mmol/L or 30 mmol/L glucose conditions for a 24 hour period and oxidative stress was induced by exposure to hydrogen peroxide (H2O2) or tumour necrosis factor- α (TNF- α ), following which the protective effect of the glucocorticoid dexamethasone was assessed. Apoptosis, necrosis and cell viability were determined using an ELISA for DNA fragmentation, an enzymatic lactate dehydrogenase assay and an MTT assay, respectively. High glucose significantly increased the susceptibility of Eahy 926 cells to apoptosis in the presence of 500 μmol/L H2O2, above that induced in normal glucose (P<0.02). A reduction of H2O2- and TNF- α -induced apoptosis occurred in both high and low glucose after treatment with dexametha-sone (P<0.05). Conclusion high glucose is effective in significantly augmenting stress caused by H2O2, but not in causing stress alone. These findings suggest a mechanism by which short term hyperglycemia may facilitate and augment endothelial damage.

Objective To explore the feasibility of dual-source CT virtual scan replace conventional scan in the CT peritoneography. Methods Prospective enrolled 29 cases who accepted peritoneal dialysis (PD) treatment and were highly suspected with PD-related complications. The patients were firstly underwent CT conventional in the fasting state by applied the dual-source CT (single energy pattern), and then 2 L dialysate which mixed with contrast medium was infused into peritoneal cavity, and the CT scan was performed again after 30 min (dual-energy pattern). Scaning data were processed by virtual post-processing software to obtain virtual CT scan imaging. Subjective evaluation (including lesions and image quality score) and objective evaluation (including the CT value, noise and signal to noise ratio) were performed on the conventional scan and virtual scan, and recorded the radiation dose. Wilcoxon test was used to analyse the differences of lesions revealing and image quality score of conventional scan imaging and virtual scan imaging, and paired t test was applied to compare the differences of radiation dose and the other quality objective evaluation index. Results There was no significant difference between conventional CT scan and virtual CT scan in the cyst, calcification, calculus, hematoma and catheterization (P>0.05). The image quality score of conventional CT scan and virtual CT scan was 5.0±0.0 and 4.9±0.4, and there was no significant difference (Z=-1.6,P=0.10). There was no statistically significant difference in CT value of muscle, kidney, subcutaneous fat, urine in bladder and intraperitoneal fluid between the two groups (P>0.05), and the CT value of liver in the virtual CT scan was higher than that in the conventional CT scan (P<0.05), but the value of bone in the virtual CT scan was lower than that in the conventional CT (P<0.05). The noise of conventional CT was significant higher than that of invirtual CT, but the SNR was significant lower than virtual CT scan (P<0.05). The effective radiation dose in the conventional CT scan and virtual CT scan were(9.6±1.4)and(15.9±4.9)mSv, and showed significant difference. Furthermore, the effective radiation dose decreased by 39.6%(6.3/15.9). Conclusion Dual-energy CT scan can replace conventional CT scan in the CT peritoneography, which can guarantee the accuracy of diagnosis and reduce radiation dose.
