RESUMO

BACKGROUND: The objective of this study is to investigate the correlation of mean platelet volume (MPV), MPV/ platelet count, and monocyte to lymphocyte ratio (MLR) between cervical cancer patients and healthy people and to evaluate the value of those parameters in early diagnosis of cervical cancer. METHODS: The study population included 137 cervical cancer patients undergoing hysterectomy and 113 healthy controls. The clinical features (age, pathology type, tumor staging, and tumor size) were collected from the hospital information system. The hematology parameters (white blood cell, red blood cell, hemoglobin, platelet count, neutrophil, lymphocyte, monocyte, mean platelet volume, platelet distribution width) are obtained in the laboratory information system. RESULTS: We found that the monocyte count and MLR value are higher in the cervical cancer group. The MPV and MPV/platelet are lower in the cervical cancer group. The receiver operating characteristic (ROC) analysis shows that MPV+MLR can generate a moderate specificity with 71.68%, sensitivity with 65.69%, and AUC with 0.718 to distinguish cervical cancer and healthy people. CONCLUSIONS: MPV/platelet and MLR may be helpful for the early diagnosis of cervical cancer. A larger clinical data analysis is necessary to evaluate the diagnostic value of hematologic parameters in cervical cancer.

RESUMO

BACKGROUND AND OBJECTIVE: Leptin receptor (LEPR) signaling inhibits apoptosis, promotes angiogenesis and proliferation, and plays a critical role in carcinogenesis. Variants of the LEPR gene may be key factors in the growth of human malignant tumors. However, the relationship between LEPR polymorphisms and hepatocellular carcinoma (HCC) has not been thoroughly investigated. Therefore, we further investigated the association between LEPR polymorphisms and the risk of chronic hepatitis B (CHB), hepatitis B virus (HBV)-related liver cirrhosis (LC), and HCC in a southern Guangxi Chinese population. METHOD: Two LEPR polymorphisms (rs1137100 and rs1137101) were genotyped in 138 CHB patients, 136 patients with LC, 149 HCC patients, and 146 healthy controls using the SNaPshot method. RESULTS: We did not observe any significant difference in the LEPR rs1137100 and rs1137101 polymorphisms between the groups of healthy controls and patients (all p > 0.05), regardless of genotypes, alleles, or haplotypes. CONCLUSIONS: Our data suggest that the genetic variants of the LEPR gene are not associated with the risk of HBV-related liver diseases (CHB, LC, and HCC) in the Guangxi population. Further studies are necessary to validate these results.

RESUMO

BACKGROUND: Albumin to fibrinogen ratio (AFR) play a crucial role in the progression and prognosis of many malignant tumors. This study aimed to comprehensively assess the diagnostic value of AFR as single markers or in combination with squamous cell carcinoma antigen (SCC-Ag), cancer antigen 125 (CA-125) in cervical cancer. METHODS: A total of 323 cervical cancer inpatients, 143 patients with cervical intraepithelial neoplasia (CIN) and 317 healthy controls were analyzed. Differences in laboratory parameters and clinicopathological features were calculated using the Mann-Whitney U or Kruskal-Wallis H test. The receiver operating characteristic (ROC) curve was used to evaluate the predicted value of AFR, alone or combined with SCC-Ag, CA-125 for the diagnosis of cervical cancer. RESULTS: The levels of AFR in patients with cervical cancer were significantly lower than those in the CIN patients and the control subjects. AFR were not only negatively correlated with the tumor stage, but also related to histology typing, lymph node metastasis, distant metastasis, depth of stromal infiltration, tumor size, and tumor stage; however, it was not associated with the blood group. AFR combined with SCC-Ag possessed a larger area under the curve (AUC; AUCAFR+SCC-Ag = 0.924, 95% confidence interval (CI) 0.900, 0.944) than AFR (P < 0.001), SCC-Ag (P < 0.001), or CA-125 (P < 0.001) did alone. CONCLUSIONS: The pretreatment levels of AFR, alone or combined with SCC-Ag, CA-125 could improve the diagnostic efficiency of cervical cancer.

RESUMO

OBJECTIVE: This study was designed to retrospectively analyze the value of the hematological parameter platelet to lymphocyte ratio (PLR) and hemoglobin to platelet ratio (HPR) in patients with colon cancer. METHODS: The hematological parameters and clinical data of 354 cases patients with colon cancer, 108 cases patients with benign colon tumors and 123 healthy controls were collected from our hospital electronic medical records. RESULTS: Compared with the colon benign tumor group and the healthy control group, the colon cancer group had an increased PLR value and a decreased HPR value. The correlation between the clinicopathological features and the laboratory parameters of colon cancer patients was analyzed, and the results showed that both PLR and HPR were associated with tumor invasion and tumor size. Compared with PLR (AUC = 0.725, 95%CI: 0.682-0.765), HPR (AUC = 0.752, 95%CI: 0.710-0.790) or carcinoembryonic antigen (CEA) (AUC = 0.710, 95%CI: 0.666-0.751) used alone, the combination with PLR and CEA (AUC = 0.790, 95%CI: 0.750-0.826) or with HPR and CEA (AUC = 0.814, 95%CI: 0.775-0.848) can improve specificity and produce greater AUC in differentiating colon cancer from benign colon cancer. CONCLUSION: Combined application of PLR, HPR, and CEA may improve the diagnostic efficacy of distinguishing between colon cancer and benign colon tumors.

RESUMO

Resistant starch (RS) was recently approved to exert a powerful influence on gut health, but the effect of RS on the caecal barrier function in meat ducks has not been well defined. Thus, the effect of raw potato starch (RPS), a widely adopted RS material, on microbial composition and barrier function of caecum for meat ducks was determined. A total of 360 Cherry Valley male ducks of 1-d-old were randomly divided and fed diets with 0 (control), 12, or 24 % RPS for 35 d. Diets supplemented with RPS significantly elevated villus height and villus height:crypt depth ratio in the caecum. The 16S rRNA sequence analysis indicated that the diet with 12 % RPS had a higher relative abundance of Firmicutes and the butyrate-producing bacteria Faecalibacterium, Subdoligranulum, and Erysipelatoclostridium were enriched in all diets. Lactobacillus and Bifidobacterium were significantly increased in the 24 % RPS diet v. the control diet. When compared with the control diet, the diet with 12 % RPS was also found to notably increase acetate, propionate and butyrate contents and up-regulated barrier-related genes including claudin-1, zonula occludens-1, mucin-2 and proglucagon in the caecum. Furthermore, the addition of 12 % RPS significantly reduced plasma TNF-α, IL-1ß and endotoxin concentrations. These data revealed that diets supplemented with 12 % RPS partially improved caecal barrier function in meat ducks by enhancing intestinal morphology and barrier markers expression, modulating the microbiota composition and attenuating inflammatory markers.
