Methods: Fifty patients with critical respiratory illness admitted to our hospital from October 2022 to September 2023 were selected and divided into an observation group and a control group after condition assessment, with 25 cases in each group. The results of cholinesterase (ChE), prealbumin (PALB), albumin (ALB), aspartate aminotransferase (AST), total protein (TP), and forced expiratory volume (FEV1)/Predicted (Pred) of the two groups were measured. Results: The ChE levels of the observation group were lower than those of the control group, while the PALB and ALB levels of the observation group were higher than those of the control group (P < 0.05). The AST, TP, and FEV1 /Pred levels of the observation group were higher than those in the control group (P < 0.05). Conclusion: Serum PALB levels can be used as the main indicator for prognosis in critically ill respiratory patients.展开更多

Methods: A total of 161 cases of pneumonia were treated in a hospital from January 2017 to June 2017 as the research objects. According to the standard of severe pneumonia, 104 cases were divided into mild pneumonia group and 57 cases were divided into severe disease group. 60 healthy persons who came to our hospital for physical examination at the same time were taken as the control group.The general data of the three groups and the level of PCT, CRP, WBC, PA were compared and analyzed. Results: The age and male ratio of severe group were higher than those of control group and mild group;compared with control group, the expression of PCT, CRP, WBC in the two pneumonia group were significantly higher, while the expression of PA was significantly lower;however, the expression of PCT, CRP, WBC in severe group were significantly higher than that in mild group, while the expression of PA in severe group was significantly lower than that in mild group. PCT has higher sensitivity, specificity and accuracy among the four indexes and it has important diagnostic value. Conclusion: PCT has higher specificity, accuracy and sensitivity in the early diagnosis of severe pneumonia, and it can be used as an important index in the early diagnosis of severe pneumonia.But the combined detection of the three indexes of PCT, CRP and WBC is helpful for diagnosing severe pneumonia more accurately.展开更多

However, to date, their effectiveness in the diagnosis of the disease remains uncertain. The purpose of the present study is to determine whether serum prealbumin and calprotectin correlate with the stage and type of histologic diagnosis. Materials-Methods: In the present study, we included 80 women aged 30 - 45 years that had either primary ovarian cancer (Stages 1 and 2) with elevated levels of CA-125 (n = 40) or were healthy (n = 40). Serum calprotectin and prealbumin levels were assessed using ELISA kits. Statistical analysis was performed with SPSS v.20.0 statistical software. Results: Both plasma prealbumin and calprotectin levels were significantly different in patients with ovarian cancer compared to healthy controls. Specifically, serum prealbumin levels showed a level towards decreasing as the stage of the disease advanced (21.2 (15.5 - 30.6) in healthy controls, 12.8 (6.9 - 16) for patients with stage 1 disease and 9.9 (4.0 - 15.5) for patients with stage 2 disease p p Conclusions: Both prealbumin and calprotectin seem to be useful markers for the identification of patients suffering from ovarian cancer.展开更多

Methods: The concentrations of total protein, albumin, prealbumin, hemoglobin of 113 colorectal cancer patients(cancer group) and 87 colorectal adenomas(adenoma group) were tested in Yixing Hospital Affiliated to Jiangsu University(China) during August 2013 to December 2013. Then the differences between the two groups were compared. Results: In colorectal cancer patients, the concentrations of serum prealbumin in 39/113 cases, total protein in 16/113 cases, albumin in 38/113, hemoglobin in 32/113 were lower than normal ranges. While, in colorectal adenoma patients, the concentrations of serum prealbumin in 4/87 cases, total protein in 2/87, albumin in 1/87, hemoglobin in 2/87 were below the detection limit. Comparative analysis showed that, average expression levels of serum prealbumin, albumin, total protein, hemoglobin in colorectal cancer patients were lower than those of colorectal adenoma patients, the difference was statistically significant(P < 0.05), and colorectal cancer patients were more likely to have lower levels of above indicators(P < 0.05). Conclusion: Compared to colorectal adenoma patients, patients with colorectal cancer have lower average expression levels, and were easier to have lower expression levels of serum albumin, albumin, total protein and hemoglobin, which suggest that colorectal cancer patients are more likely to have metabolic change, and clinic notable.展开更多

文摘BACKGROUND Anastomotic leakage(AL)is one of the severest complications after laparoscopic surgery for middle/low rectal cancer,significantly impacting patient outcomes.Identifying reliable predictive factors for AL remains a clinical challenge.Serum nutritional biomarkers have been implicated in surgical outcomes but are un-derexplored as predictive tools for AL in this setting.Our study hypothesizes that preoperative serum levels of prealbumin(PA),albumin(ALB),and transferrin(TRF),along with surgical factors,can accurately predict AL risk.AIM To determine the predictive value of preoperative serum nutritional biomarkers for rectal cancer AL following laparoscopic surgery.METHODS In the retrospective cohort study carried out at a tertiary cancer center,we examined 560 individuals who underwent laparoscopic procedures for rectal cancer from 2018 to 2022.Preoperative serum levels of PA,ALB,and TRF were measured.We employed multivariate logistic regression to determine the independent risk factors for AL,and a predictive model was constructed and evaluated using receiver operating characteristic curve analysis.RESULTS AL occurred in 11.96%of cases,affecting 67 out of 560 patients.Multivariate analysis identified PA,ALB,and TRF as the independent risk factor,each with an odds ratio of 2.621[95%confidence interval(CI):1.582-3.812,P=0.012],3.982(95%CI:1.927-4.887,P=0.024),and 2.109(95%CI:1.162-2.981,P=0.031),respectively.Tumor location(<7 cm from anal verge)and intraoperative bleeding≥300 mL also increased AL risk.The predictive model demonstrated an excellent accuracy,achieving an area under the receiver operating characteristic curve of 0.942,a sensitivity of 0.844,and a specificity of 0.922,demonstrating an excellent ability to discriminate.CONCLUSION Preoperative serum nutritional biomarkers,combined with surgical factors,reliably predict anastomotic leakage risk after rectal cancer surgery,highlighting their importance in preoperative assessment.
