ABSTRACT
Objective:To investigate the correlations between albumin globulin ratio (AGR) , platelet lymphocyte ratio (PLR) , neutrophil lymphocyte ratio (NLR) and efficacy of chemotherapy for patients with metastatic colorectal cancer (mCRC) .Methods:The clinical data of 107 mCRC patients who were treated at the First Hospital of Shanxi Medical University for chemotherapy from January 2016 to September 2020 were selected, and the values of AGR, NLR and PLR before chemotherapy and after 3 cycles of chemotherapy were collected for retrospective analysis. After 3 cycles, patients were divided into three groups according to efficacy evaluation: partial response (PR) group, stable disease (SD) group and progressive disease (PD) group. The changes of AGR, PLR and NLR values before and after chemotherapy, and the relationships between the degrees of changes and the therapeutic effects were analyzed.Results:There were 18 cases in the PR group, 53 cases in the SD group and 36 cases in the PD group. There were no significant differences in age, sex, distant metastasis site, cancer site, T stage and N stage among the three groups ( F=0.33, P=0.721; χ2=2.94, P=0.230; χ2=2.34, P=0.674; χ2=0.80, P=0.669; χ2=5.68, P=0.224; χ2=2.06, P=0.375) . The AGR, PLR and NLR values before chemotherapy in the PR group were 1.57±0.19, 180.05±102.77 and 5.19 (4.50, 5.83) , and they were 1.45±0.23, 115.81±55.79 and 1.83 (1.06, 2.84) after chemotherapy, with statistically significant differences ( t=2.32, P=0.033; t=2.84, P=0.011; Z=-2.94, P=0.003) . In the SD group, AGR, PLR and NLR values before chemotherapy were 1.66 (1.40, 1.77) , 158.18 (103.81, 236.26) , 2.41 (1.75, 4.07) , and they were 1.35 (1.15, 1.60) , 123.85 (94.86, 176.44) , 1.49 (1.27, 2.33) after chemotherapy, with statistically significant differences ( Z=-4.51, P<0.001; Z=-3.31, P=0.001; Z=-3.90, P<0.001) . The AGR, PLR and NLR values in the PD group before chemotherapy were 1.60 (1.48, 1.87) , 122.07 (77.14, 175.72) , 2.37 (1.28, 4.20) , and they were 1.26 (1.08, 1.40) , 176.39 (139.89, 280.64) and 4.71 (3.71, 6.96) after chemotherapy, with statistically significant differences ( Z=-4.49, P<0.001; Z=-3.42, P=0.001; Z=-4.18, P<0.001) . The differences in AGR ( OR=3.66, 95% CI: 1.29-10.39, P=0.015) , PLR ( OR=0.99, 95% CI: 0.99-1.00, P<0.001) and NLR ( OR=0.59, 95% CI: 0.49-0.70, P<0.001) before and after chemotherapy were related to clinical efficacy. The greater the difference of AGR, the worse the short-term efficacy. The greater the difference of PLR and NLR, the better the short-term efficacy. The correlation between the changes in AGR, PLR and NLR before and after treatment and the clinical efficacy was sorted in descending order Δ NLR>Δ PLR>Δ AGR ( r=-0.68, P<0.001; r=-0.51, P<0.001; r=0.25, P=0.009) . Conclusion:The changes in the levels of AGR, NLR and PLR before and after chemotherapy are correlated with the short-term efficacy of mCRC, and it has certain significance for monitoring the curative effects of patients and further optimizing the treatment plan.
ABSTRACT
Organic anion transporting polypeptide 1B1 and 1B3 (OATP1B1/3) as important uptake transporters play a fundamental role in the transportation of exogenous drugs and endogenous substances into cells. Rat OATP1B2, encoded by the gene, is homologous to human OATP1B1/3. Although OATP1B1/3 is very important, few animal models can be used to study its properties. In this report, we successfully constructed the S knockout (KO) rat model using the CRISPR/Cas9 technology for the first time. The novel rat model showed the absence of OATP1B2 protein expression, with no off-target effects as well as compensatory regulation of other transporters. Further pharmacokinetic study of pitavastatin, a typical substrate of OATP1B2, confirmed the OATP1B2 function was absent. Since bilirubin and bile acids are the substrates of OATP1B2, the contents of total bilirubin, direct bilirubin, indirect bilirubin, and total bile acids in serum are significantly higher in KO rats than the data of wild-type rats. These results are consistent with the symptoms caused by the absence of OATP1B1/3 in Rotor syndrome. Therefore, this rat model is not only a powerful tool for the study of OATP1B2-mediated drug transportation, but also a good disease model to study hyperbilirubinemia-related diseases.
ABSTRACT
The pretreatment serum albumin/globulin ratio (AGR) has been used as a prognostic biomarker for various cancer types. However, the prognostic value of the AGR for prostate cancer, especially for metastatic prostate cancer (mPCa) after maximal androgen blockade (MAB), remains unclear. The aim of this study was to evaluate the prognostic value of the pretreatment serum AGR for mPCa treated with MAB. This retrospective study included 214 mPCa patients receiving MAB from October 2007 to March 2017. The correlation of the AGR with survival was estimated using Kaplan-Meier analysis and Cox proportional hazards models. The cutoff value of the AGR was 1.45 according to the receiver operating characteristic curve. Kaplan-Meier analysis demonstrated that patients with a low AGR (<1.45) had poor outcomes in terms of progression-free survival (PFS) and cancer-specific survival (CSS). Multivariate Cox analyses showed that the AGR was an independent predictor of PFS (hazard ratio [HR] = 0.642; 95% confidence interval [CI]: 0.430-0.957; P = 0.030) and CSS (HR = 0.412; 95% CI: 0.259-0.654; P < 0.001). Furthermore, in a subset of 79 patients with normal serum albumin levels (≥40.0 g l-1), the serum AGR remained an independent predictor of CSS (P = 0.009). The pretreatment AGR was an independent prognostic biomarker for PFS and CSS in patients with mPCa receiving MAB. In addition, the AGR remained effective for the prediction of CSS in patients with normal albumin levels (≥40 g l-1). However, further prospective studies are needed to confirm our conclusions.
ABSTRACT
Objective@#To investigate the prognostic value of albumin/globulin ratio on postoperative survival outcomes in patients with hepatocellular carcinoma.@*Methods@#Data of 630 patients with HCC, who underwent surgical resection from February 2009 to July 2013, were retrospectively analyzed. Patients were divided into low-value group (A/G < 1.5, defined as L group) and high-value group (A/G≥1.5, defined as H group), and their distribution characteristics were observed with the normal A/G threshold value. Independent risk factors’ affecting survival and prognosis was analyzed with univariate and multivariate Cox’s regression model. Survival trend of all patients with low-value and high-value groups in A, B and C of Barcelona stage (BCLC stage) were analyzed using the Kaplan-Meier method.@*Results@#Multivariate analysis showed that preoperative A/G ratio (P = 0.007), alpha-fetoprotein (P < 0.001), gamma-glutamyltransferase (P = 0.006), RBC (P = 0.014), international normalized ratio (P = 0.009), preoperative BCLC staging (P < 0.001) and number of tumors (P = 0.003), and intraoperative blood transfusion (P < 0.001) were independent prognostic factors affecting long-term survival in HCC patients. The median overall survival time in-group L was 15 months, significantly lower than that in group H of 42 months (P < 0.001). Stratified analysis showed that the short-term survival advantage of patients with high A / G value was limited to those with Barcelona stage A (P < 0.001), and disappeared in patients with Barcelona stage B and C (P > 0.05). The long-term survival advantage existed in patients with Barcelona stage A (P < 0.001), B (P < 0.05), and disappeared in C (P > 0.05).@*Conclusion@#Preoperative albumin/globulin ratio can predict postoperative prognosis and survival, and direct towards the treatment for early stage of HCC and thus representing as an indicator of high clinical value.

ABSTRACT
Aim: The aim of this study was to examine the effect of ethanolic extract of coriander leaves as a potent in vivo antioxidant agent in an effort of finding possible sources of antioxidants for future use in food and pharmaceutical formulations. Study Design: Randomized controlled experiment. Place and Duration of Study: Experimental Animal Unit, Drug Radiation Research Department, National Center for Radiation Research and Technology, Cairo Egypt. Methodology: Antioxidant activity of ethanol extract of coriander leaves was estimated by oxidative stress induced by radiation exposure with the dose of 4 Gy, Silymarin was used as a reference antioxidant drug in female albino rat. Results: Results of experiment revealed that radiation exposure caused a significant increase in serum caspase3 (0.870± 0.086), alanine transaminase (ALT) activity (24.43± 5.02) as well as urea (42.53± 6.11) and creatinine (0.865± 0.064) levels with an increase in liver and kidney lipid peroxidation (MDA) (307.0± 29.22 & 285.5± 48.93) respectively, while decrease in serum albumin (3.003± 0.355), protein (8.66± 0.436) as well as glutathione (GSH) contents of liver and kidney tissues (63.24± 12.19 & 17.38± 1.414) were estimated respectively. In addition serum globuline level and albumin /globuline ratio showed no significant changes. On the other hand, the administration of coriander (600 mg/kg bw) and silymarin (70 mg/kg bw) pre-treatment effectively prevented these alterations and maintained the antioxidant status. Conclusion: Data from present results revealed that Coriandum Sativum act as an antioxidant agent due to its free radical scavenging and cytoprotective activity.
ABSTRACT
The early prediction of pregnancy-induced hypertension (PIH) is based on the demonstration of increased sympathetic activity in early part of pregnancy. However, the mechanisms that increase sympathetic activity in PIH have not yet been fully elucidated. Therefore, in the present study we have investigated the link of albumin-globulin ratio (AGR) to sympathovagal imbalance in PIH patients. Spectral analysis of HRV was performed in three groups of subjects (Group I: normal pregnant women; Group II: pregnant women with risk factors for PIH, but did not develop PIH; Group III: pregnant women with risk factors and developed PIH) and their biochemical parameters including AGR were recorded. It was observed that LF-HF ratio, the most sensitive indicator of sympathovagal balance was significantly high (P<0.01) since early pregnancy in group III compared to other groups, which was considerably correlated with AGR in group III (PIH subjects). It was suggested that alteration in AGR could have direct contribution to the sympathovagal imbalance that plays a critical role in the genesis of PIH.
