Methods The clinical data of 12 patients with Still’s disease from January 2007 to December 2009 were retrospective analyzed. The clinical characteristics of the disease were observed. Results Twelve patients had high fever (body temperature≥39.0℃), evanescent eruption, arthralgia, increase of leucocyte and neutrophilic granulocyte (leucocyte≥15.0×109/L, neutrophilic granulocyte≥80%), blood sedimentation, and C-reactive protein, increase of serum ferritin, bone marrow smear being hyperplasticmyelogram, as well as the tumefaction of angina, liver, spleen, and lymphaden. Glucocorticoid was the main measure of the treatment. Conclusions Clinical presentation of adult Still’s disease is various with involvement of many systems with lack of specificity of the lab inspection. Obvious increase of detected value of serum ferritin attributes greatly to the diagnosis. The prognosis of the patients who have undergone glucocorticoid treatment is very good.
ObjectiveTo explore the relationship between the levels of transferrin (TRF), prealbumin (PAB) and total bile acids (TBA) in serum and the loss of the hepatic reserve function in primary liver cancer (PHC) patients and the importance of the former factors for diagnosis of PHC. MethodsA total of 154 patients with PHC collected between March 2010 and February 2013 were included in our study. Based on the information of hepatic reserve function and the Child-Pugh classification standard, the patients were divided into Child-Pugh-A, B, and C groups with 67, 55 and 42 patients respectively. Another 58 healthy subjects were selected as the control group. Serum TRF, PAB and TBA levels were measured by automated chemiluminescence immunoassay, immune turbidimetric assay and enzymatic cycling respectively, and they were compared among the groups. ResultsTRF level of patients in the control group and Child-Pugh-A, B, and C groups was respectively (2.574±0.214), (1.618±0.135), (0.988±0.121), and (0.314±0.107) g/L, with significant differences among the groups (P<0.05). PAB level of patients in four groups was respectively (269.32±37.29), (165.22±21.01), (123.24±31.15), and (83.66±19.74) mg/L, with significant differences among the groups (P<0.05). TBA level in the above four groups was respectively (9.16±2.48), (65.13±4.25), (133.62±8.44), and (250.73±21.59) μmol/L, and there was also significant differences among the groups. A positive correlation between serum TRF and PAB was found (r=0.927, P<0.001), and negative correlations between serum TBA level and serum TRF and between TBA and PAB were found (r=-0.454, P<0.001; r=-0.432, P<0.001, respectively). ConclusionSerum TRF, PAB and TBA levels are closely related to the hepatic reserve function in PHC patients, and they can be used as an important indicator for PHC diagnosis.
Objective To explore the relationship between the level of serum ferritin (SF) and liver damage in patients with chronic hepatitis B (CHB). Methods The concentration of serum ferritin of 98 patients with CHB from July to October 2014 was measured, and then correlation analysis was performed to analyze the correlation between SF and such indexes as serum tumor marker α-fetoprotein, biochemical markers [alanine amino transferase (ALT), aspartate amino transferase (AST), total protein (TP), albumin and total bilirubin (TBIL)], and hepatitis B serum markers (hepatitis B surface antigen, hepatitis B surface antibody, hepatitis B e antigen, hepatitis B e antibody, and hepatitis B core antigen). Serum hepatitis B virus DNA (HBV-DNA) viral load was also tested, and then the discrepancy of SF levels in the high and low viral load groups was analyzed. Results The average concentration of the abnormally elevated SF was (878.69±837.98) ng/mL. The SF mean difference between low-load HBV-DNA and high-load HBV-DNA was statistically significant (P < 0.05). Serum ferritin levels were independently and positively correlated with ALT, AST, and TBIL (P < 0.01) and inversely correlated with TP and albumin (P < 0.01). Conclusion The rise of SF is associated with liver damage, which can reflect the state of inflammation of patients with CHB.
ObjectiveTo systematically review the accuracy of serum ferritin (SF) for detecting breast cancer. MethodsWe electronically and comprehensively searched databases including CNKI, WanFang Data, CBM, VIP, PubMed, EMbase and The Cochrane Library (Issue 5, 2013) up to April 2013, for diagnostic tests about using SF for detecting breast cancer. Four reviewers independently screened literature according to the exclusion and inclusion criteria, extracted data, and assessed methodological quality of included studies. Then, meta-analysis was performed using Meta-Disc 1.4 software and funnel plots were drawn using Stata 12.0 software. ResultsA total of 19 studies were finally included involving 2 977 patients. The results of meta-analysis showed that:Sen, Spe, +LR, -LR, DOR were 0.51 (95%CI 0.48 to 0.53), 0.91 (95%CI 0.89 to 0.92), 5.32 (95%CI 3.72 to 7.60), 0.45 (95%CI 0.35 to 0.57), and 13.22 (95%CI 7.22 to 24.18); SROC area under the curve (AUC) was 0.920 5 and Q* was 0.853 9. Besides, when cut off value was 101-150 μg/L, Sen, Spe, AUC and Q* were the largest, and the best cut-off value was probably 150 μg/L. ConclusionSF has relatively high Sen and Spe in the diagnosis of breast cancer which could not be used as specific index. Heterogeneities exist among the research results, which are possibly associated with researchers, severity of disease, instrument types, sources of reagents, and cut off values. Due to limited quality and quantity of the included studies, the above conclusion should be treated with caution, and in clinic, combing other tumour markers with SF is recommended in detecting breast cancer to augment accuracy.
Objective To detect the expression of transferrin receptor 1 (TfR1) in laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma, and parotid carcinoma, exploring the relationship between the expression of the four cancers and their occurrence and progression. Methods A total of 24 specimens of head-neck carcinoma were collected in surgery from April 2015 to March 2017, including 8 cases of laryngeal carcinoma, 8 cases of thyroid carcinoma, 4 cases of maxillary sinus carcinoma, and 4 cases of parotid carcinoma. Fluorescence quantitative polymerase chain reaction technique for TfR1 mRNA and western blot for TfR1 protein was performed in those tumor tissues and their adjacent normal tissues. Results The relative expression level of TfR1 mRNA in the tumor tissues of laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma, and parotid carcinoma was 0.078±0.002, 0.065±0.044, 0.076±0.014, 0.067±0.004, respectively; while the relative expression level of TfR1 mRNA in the adjacent normal tissues of the four cancers was 0.021±0.012, 0.011±0.007, 0.017±0.013, 0.028±0.007, respectively. The relative expression level of TfR1 protein in the tumor tissues of laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma, and parotid carcinoma was 0.668±0.206, 0.640±0.066, 0.452±0.095, 0.925±0.221, respectively; while the relative expression level of TfR1 protein in the adjacent normal tissues of the four cancers was 0.359±0.113, 0.424±0.096, 0.280±0.093, 0.519±0.037, respectively. The expression levels of TfR1 mRNA and TfR1 protein in the tumor tissues of the four cancers were all higher than those in their adjacent normal tissues (P<0.05). Conclusions The expression levels of TfR1 mRNA and TfR1 protein in the tumor tissues of laryngeal carcinoma, thyroid carcinoma, maxillary sinus carcinoma and parotid carcinoma are up-regulated. TfR1 may be involved in the occurrence and progression of the four cancers, and it may be responsible for tumor proliferation by providing necessary raw materials for the proliferation of tumor cells.
ObjectivesTo systematically review the association between pretreatment serum ferritin (SF) concentration and prognosis in lung cancer patients.MethodsDatabases including PubMed, EMbase, Web of Science, CNKI, VIP and WanFang Data were electronically searched to identify cohort studies on the relationship between the pretreatment SF concentration and prognosis of lung cancer patients from inception to January, 2020. Literature screening, data extraction and quality evaluation of included studies were independently performed by two reviewers. Then, meta-analysis was conducted by Stata 12.0 software.ResultsA total of 8 cohort studies involving 1 002 lung cancer patients were included. The results of meta-analysis indicated that patients with higher pretreatment SF concentration had poorer overall survival (HR=1.70, 95%CI 1.06 to 2.73, P=0.029) compared with patients with lower pretreatment SF concentration. Subgroup analysis based on the pathological type manifested showed that pretreatment SF concentration only had high prognostic value in small cell lung cancer patients (HR=4.78, 95%CI 2.83 to 8.05, P<0.001).ConclusionsLung cancer patients with high pretreatment SF level have worse overall survival. Pretreatment SF concentration may serve as an independent prognostic factor in lung cancer, especially in small cell lung cancer. Due to the limited quality and quantity of included studies, more prospective well-designed studies are required to verify above conclusions.
