Value of the inflammatory markers albumin, C-reactive protein, erythrocyte sedimentation rate, and interleukin-6 in predicting hepatocellular carcinoma with different types of portal vein thrombosis / 临床肝胆病杂志

Objective To investigate the biochemical and routine blood parameters in hepatocellular carcinoma (HCC) patients with portal vein blood thrombus (PVBT) or portal vein tumor thrombosis (PVTT), as well as the expression level and clinical significance of inflammatory indices in patients with different types of PVBT. Methods A total of 51 HCC patients with PVBT and 37 HCC patients with PVTT who were diagnosed and treated in The Second Affiliated Hospital of Zhengzhou University from January 2016 to December 2020 were enrolled as PVBT group and PVTT group, respectively, and 50 HCC patients without portal vein thrombosis who were hospitalized during the same period of time were enrolled as control group. General clinical data and laboratory test results were collected from the three groups. The chi-square test or the Kruskal-Wallis rank sum test was used for comparison of categorical data between groups; a one-way analysis of variance was used for comparison of normally distributed continuous data between groups, and the Kruskal-Wallis rank sum test was used for comparison of non-normally distributed continuous data between groups. The receiver operating characteristic (ROC) curve was plotted to investigate the expression levels of albumin (Alb), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), and interleukin-6 (IL-6) in the PVBT group and the PVTT group, and the area under the ROC curve (AUC) was calculated to analyze their value in predicting different types of thrombosis. Results There were no significant differences in general data and conventional biochemical parameters between the three groups (all P > 0.05), while there were significant differences in the inflammatory indices Alb, CRP, ESR, and IL-6 between the three groups ( H =10.207, 24.465, 8.917, and 37.584, P =0.006, P < 0.001, P =0.012, and P < 0.001), and further analysis between two groups showed that the PVTT group had a significantly lower level of Alb and significantly higher levels of CRP, ESR, and IL-6 than the PVBT group and the control group, and the PVBT group had significantly higher levels of CRP and IL-6 than the control group (all P < 0.05). The ROC curve analysis showed that Alb, CRP, ESR, and IL-6 had an AUC of 0.659, 0.826, 0.679, and 0.873, respectively, in the PVTT group, as well as an AUC of 0.508, 0.635, 0.503, and 0.701, respectively, in the PVBT group. Conclusion HCC patients with PVTT tend to have high expression levels of the inflammatory indices IL-6, CRP, and ESR and a low expression level of Alb, and their predictive value decreases successively, while HCC patients with PVBT tend to have relatively low expression levels IL-6, CRP, and ESR and a relatively high expression level of Alb. IL-6 and CRP have a certain value in predicting PVBT, while ESR and ALB have little predictive value.

Relationship between clinical features in 371 cases of colorectal polyps with fecal occult blood and CEA / 重庆医学

Objective To investigate the basic clinical features in 371 cases of colorectal polyps and its relationship with fecal occult blood and carcinoembryonic antigen(CEA).Methods The retrospective analysis was performed on 371 inpatients with colo-rectal polyps.The relationship among gender,number of polyps and polyps anatomical site in different ages of patients was investi-gated,and the relationship between fecal occult blood and CEA with polyp canceration was analyzed by 1.5?3.0 years follow-up. Results Among 371 cases of colorectal polyps,the female patients were gradually increased and single polyp was gradually de-creased along with the age increase;due to different ages,there was the statistically significant difference in the polyp locations (χ2 =9.759,P=0.045);the distribution difference of the patients with polyp canceration among three age groups was statistically significant(χ2 =5.138,4.107,13.153,P<0.05).The cases of fecal occult blood positive and CEA abnormal increase were gradual-ly increased with age increasing(χ2 =15.544,11.959,P<0.01);with the number of polyps increasing,the cases of fecal occult blood positive showed the increasing trend(χ2 =14.043,P=0.001);the canceration rate in colorectal polyp cases of fecal occult blood positive and CEA abnormal increase was significantly higher than that in the cases of fecal occult blood negative and CEA normal range(χ2 =40.165,43.249,all of P< 0.001).Conclusion The fecal occult blood test and CEA detection results have a certain significance to the follow up for preventing colorectal polyps canceration.

The expression and significance of CD276 and CD133 in colorectal cancer and precancerous lesions / 中华内科杂志

In order to study the significance of CD276 and CD133 in the development and progression of colorectal cancer (CRC),the expression of CD276 and CD133 was detected by immunohistochemistry in CRC and precancerous lesions.The results showed that the intensity of CD276 and CD133 in CRC samples was higher than that in adenoma group and non-adenoma group.CD276 and CD133 single and double positive expression were significantly correlated with CRC lymph node metastasis,distant metastasis and survival.CD276 and CD133 are significantly correlated to the development and progression of CRC and associated with poor prognosis.

Carnosic acid protects against acetaminophen-induced hepatotoxicity by potentiating Nrf2-mediated antioxidant capacity in mice

Acetaminophen (APAP) overdose is one of the most common causes of acute liver failure. The study aimed to investigate the protective effect of carnosic acid (CA) on APAP-induced acute hepatotoxicity and its underlying mechanism in mice. To induce hepatotoxicity, APAP solution (400 mg/kg) was administered into mice by intraperitoneal injection. Histological analysis revealed that CA treatment significantly ameliorated APAP-induced hepatic necrosis. The levels of both alanine aminotransferase (ALT) and aspartate transaminase (AST) in serum were reduced by CA treatment. Moreover, CA treatment significantly inhibited APAP-induced hepatocytes necrosis and lactate dehydrogenase (LDH) releasing. Western blot analysis showed that CA abrogated APAP-induced cleaved caspase-3, Bax and phosphorylated JNK protein expression. Further results showed that CA treatment markedly inhibited APAP-induced pro-inflammatory cytokines TNF-alpha, IL-1beta, IL-6 and MCP-1 mRNA expression and the levels of phosphorylated IkappaBalpha and p65 protein in the liver. In addition, CA treatment reduced APAP- induced hepatic malondialdehyde (MDA) contents and reactive oxygen species (ROS) accumulation. Conversely, hepatic glutathione (GSH) level was increased by administration of CA in APAP-treated mice. Mechanistically, CA facilitated Nrf2 translocation into nuclear through blocking the interaction between Nrf2 and Keap1, which, in turn, upregulated anti-oxidant genes mRNA expression. Taken together, our results indicate that CA facilitates Nrf2 nuclear translocation, causing induction of Nrf2-dependent genes, which contributes to protection from acetaminophen hepatotoxicity.

Correlation of blood glucose, blood pressure and body weight with pancreatic cancer / 中华老年医学杂志

Objective To investigate the correlation of blood glucose,blood pressure and body weight with pancreatic cancer.Methods From January 2011 to December 2013,110 patients diagnosed with pancreatic cancer in our hospital were selected as the observation group and 110 agematched cases without cancer during the same period were selected as the control group.The percentages of patients with diabetes,hypertension and elevated body mass index (BMI) were analyzed in both groups.Results The number of patients with diabetes was higher in the observation group than in the control group (32 cases or 29.1％ vs.16 cases or 14.6％,P＜0.05).The proportions of pancreatic cancer patients with diabetes duration ≤ 2 years,2～5 years and 5～10 years were higher in the observation group than in the control group (P＜0.05).The proportion of subjects with increased BMI was higher in the observation group than in the control group (24.6％ or 27cases vs.10.9％ or 12 cases,P＜0.05).The proportions of patients with diabetes combined with increased BMI and of patients with hypertension and increased BMI were higher in the observation group than in the control group (17.3％ or 19 cases vs.2.7％ or 3 cases,10.9％ or 12 cases vs.2.7％ or 3 cases,respectively,P＜ 0.05 for both).Conclusions Diabetes,hypertension,and elevated BMI can be considered as risk factors for pancreatic cancer,and it is possible that these factors are involved in the development of pancreatic cancer.
