ABSTRACT

Objective:To explore whether the 15-minute retention rate (R15) of indocyanine green (ICG) in the indocyanine green excretion test and the effective hepatic blood flow (EHBF) can predict the occurrence of mild hepatic encephalopathy (MHE).Methods:Using the convenience sampling method, we collected clinic data from 153 patients diagnosed with liver cirrhosis or liver failure from June 2019 to December 2019 in the Third Affiliated Hospital of Sun Yet-sen University in Guangzhou. We screened the MHE patients with the number connect test-A and the digital symbol test, and analyzed the clinical data. By taking different values for R15 and EHBF as cut-off points, the significance of the two factors in predicting MHE is explored respectively.Results:The incidence of MHE was 38.56% (59/153). Single factor analysis showed that the difference of Child-Pugh grade between the MHE group and the non-MHE group was statistically significant ( χ2 value was 7.606, P<0.05), while the differences between cirrhosis and liver failure diagnosis, fasting blood glucose, and serum creatinine were not statistically significant ( P>0.05). When most points between 0.11 and 0.61 were selected as normal and abnormal cut-off points of R15, R15 had statistical significance ( P<0.05) and when R15 selected 0.18, it was most significant (Fisher exact test P=0.00024). When most points between 0.08 and 0.76 were selected as normal abnormal cut-off points of EHBF, EHBF had statistical significance ( P<0.05) and when EHBF selected 0.25, it was most significant (Fisher exact test P=0.00022). Through Logistic stepwise regression analysis, the risk factors for MHE were R15 and EHBF. The ROC curve was used to illustrate the predictive effects of two factors on MHE. Conclusions:The incidence of MHE in patients with cirrhosis or liver failure is high. When R15≥0.18 or EHBF≤0.25 L/min, R15 and EHBF in indocyanine green excretion test can better predict the occurrence of MHE than Child-Pugh classification, and can be help to evaluate and manage patients in time.

ABSTRACT

Objective To study the correlation between the level of CaMKIV and essential hypertension (EH) in Shihezi community. Methods One hundred and forty-six patients with EH and 142 with normal blood pressure are enrolled from 15 communities in shihezi. We collected the clinical data, including blood pressure, body mass index, waist circumference, blood lipids. The serum level of CaMKIV was detected using an enzyme linked immunosorbent assay. Results The serum level of CaMKIV in the EH group was significantly lower than that in the normal blood pressure group (P < 0.05). The serum CaMKIV was negatively correlated with systolic BP and diastolic BP (r = -0.304, -0.452, all P < 0.05), with more obvious correlation with patients whose diastolic blood pressure was over 100 mmHg (r = -0.571, P < 0.05). Conclusions The serum level of CaMKIV is negatively correlated with EH, which is an independent factor of EH.

ABSTRACT

Human cancers arise from an imbalance of cell growth and cell death.Critical factors that control the balance are those regulate the cell cycle.Several molecular effectors have been identified to be able to regulate specific phases of the cell cycle,including cyclins,cyclin-dependent kinases (CDKs) and CDK inhibitors.Notably,deficiency of two G1-checkpoint CDK inhibitors-p21 (CDKN1A) and p27 (CDKN1B)-has been implicated to be correlated with initiation or progression of many human malignancies or cancer cells drug-resistance.However,contradict reports also suggested that p21 and p27 could promote tumor progression.Here,we summarized the historic and recent studies on these two CDK inhibitors,including their identification as well as their roles in carcinogenesis and drug resistance.
