CONCLUSIONS:JCI standard is of significance to the promotion of PIVAS management,work level and quality,and safe and rational use of drugs in the clinic.

Objective To evaluate the clinical value of fasting blood glucose (FBG) in the diagnosis of multiple organ dysfunction syndrome (MODS) caused by pulmonary infection in elderly patients with diabetes. Methods Patients over 65 years old with diabetic pulmonary infection admitted to Department of Cadres Ward of Bethune International Peace Hospital of PLA from July 2015 to December 2016 were enrolled. According to the patient's highest FBG level during pulmonary infection, all patients were divided in two groups. The cases whose FBG ≥8.83 mmol/L were served as suspicious multiple organ dysfunction syndrome in the elderly (MODSE) group, and those had FBG < 8.83 mmol/L were served as suspicious non-MODSE group. The incidence of MODSE in suspicious MODSE group and suspicious non-MODSE group was compared. The receiver operating characteristic curve (ROC) was drawn, and the clinical value of highest FBG in the diagnosis of MODSE caused by pulmonary infection in elderly patients with diabetes was assessed. Results 119 elderly patients with diabetes and pulmonary infection were enrolled in the analysis. All patients were male, with age of 76-105 years with an average of (89.41±4.16) years. Among 119 patients, 55 of them with suspected MODSE, 64 of them with suspected non-MODSE. The incidence of MODSE in suspicious MODSE group was significantly higher than that in suspicious non-MODSE group (78.2% vs. 12.5%), with statistically significant difference (χ2 = 52.108, P = 0.000). The area under the ROC curve of the highest FBG for diagnosis of MODSE was 0.895, and 95% confidence interval (95%CI) was 0.839-0.951 (P < 0.001). When using FBG ≥ 8.83 mmol/L to diagnose MODSE induced by pulmonary infection in elderly patients with diabetes, the sensitivity was 84.3% and the specificity was 82.4%. Conclusion FBG ≥ 8.83 mmol/L, as an indicator reflecting the changes of metabolic function, have a diagnostic value for MODSE caused by pulmonary infection in elderly patients with diabetes.

Objective To observe the mRNA expression levels of POT1 in peripheral blood mononuclear cells of acquired aplastic anemia patients with different syndrome, and explore its relationship with acquired aplastic anemia and its TCM syndrome. Methods Peripheral blood mononuclear cells of 52 cases with acquired aplastic anemia and 20 cases as control group were collected to detect mRNA expression of POT1 by using real-time quantitative polymerase chain reaction (RT-qPCR), and its relation with TCM syndrome was analyzed. Results The expression levels of POT1 mRNA in patients with acquired aplastic anemia were lower significantly than control group (P<0.05). The expression levels of POT1 mRNA in patients with deficiency of kidney-yin were lower than patients with deficiency of kidney-yang, and it was lowest in patients with kidney deficiency of both yin and yang. There was significant correlation between the expression levels of POT1 mRNA and age (r=0.374, P=0.038). Conclusion The changes in expression levels of POT1 play a role in the pathogenesis of acquired aplastic anemia. There is correlation between mRNA expression level of POT1 in peripheral blood mononuclear cells and TCM syndrome.

AIM To compare the effects of probimane( Pro), bimolane ( Bim) and razoxane( Raz) on animal tumor metastasis in vivo . METHODS A biological inoculation method for assessment of pulmonary metastasis of Lewis lung carcinoma(3LL) was employed. RESULTS Pro and Bim inhibited the pulmonary metastasis of 3LL both from d 2 and from d 8 injections, but Raz only inhibited the pulmonary metastasis of 3LL from d 2 injections. Pro inhibited the pulmonary metastasis of 3LL more potently than Bim did at equitoxic dosage. CONCLUSION Pro is better in the treatment of pulmonary metastasis of 3LL than Raz for its possible novel molecular mechanisms.

Objective:To investigate the value of synthetic MRI for evaluating lumbar intervertebral disc degeneration.Methods:A total of 414 lumbar intervertebral discs from 85 patients were included prospectively from September 2018 to February 2019 in First Affiliated Hospital of China Medical University. The T 1, T 2 and proton density (PD) mapping were generated from synthetic MRI. Two doctors measured the T 1, T 2 and PD values to evaluate intraobserver agreement by using ICC. For Pfirrmann grade comparisons, the variables with normal distribution were analyzed with the one-way analysis of variance, whereas those with skewed distribution were analyzed with the Kruskal-Wallis H test. Furthermore, the ROC curves were used on significant parameters to evaluate their diagnostic efficacy. The Z test was used to compare the differences of area under the ROC curves (AUC). Results:The color of the quantitative mapping changed along with the increase of the Pfirrmann grade of the intervertebral discs, which corresponded to the decrease of the T 2WI signal intensity. The ICC values of the quantitative values of nucleus pulposus indicated excellent agreement (ICC>0.900), followed by anterior annulus fibrosus (ICC>0.700) and then the posterior annulus fibrosus (ICC>0.600). The results of the adjacent Pfirrmann grade comparisons were as follows: between Pfirrmann grade Ⅰ and Ⅱ, the differences of T 2 and PD values of nucleus pulposus were statistically significant ( P=0.004 and P<0.001, respectively); between Pfirrmann grade Ⅱ and Ⅲ, the differences of T 1, T 2 and PD values of nucleus pulposus were statistically significant (all P<0.001); between Pfirrmann grade Ⅲ to Ⅳ, the T 1, T 2 and PD values of nucleus pulposus (all P<0.001) and the T 1 and PD values of posterior annulus fibrosus ( P=0.025, P<0.001, respectively) had statistically significant differences; between Pfirrmann grade Ⅳ to Ⅴ, the difference of T 2 values of nucleus pulposus were statistically significant ( P=0.031). The AUC of T 2 values of nucleus pulposus between Pfirrmann grade Ⅱ to Ⅲ and grade Ⅳ to V were higher than those of the PD values ( Z=2.443, 3.591 and P=0.015,<0.001). Conclusions:Synthetic MRI can quantitatively evaluate lumbar disc degeneration, in which the T 2 value of nucleus pulposus may be the most effective parameter with high repeatability.
