 Methods: We retrospectively collected 204 patients with severe pneumonia who were hospitalized from January 1, 2019 to December 1, 2021 in our hospital (respiratory intensive care unit (RICU)), and divided into survival group (160 patients) and death group (44 patients) according to their hospitalization outcome. The relationship between lactate dehydrogenase and apolipoprotein A1 levels and general information, disease, and treatment needs of patients with severe pneumonia was analyzed, and lactate dehydrogenase, apolipoprotein A1, neutrophil-to-lymphocyte ratio, hematocrit, C-reactive protein, calcitoninogen, D-dimer, Acute Physiology and Chronic Health Status Rating System II, and Pneumonia Severity Index scores were compared between the survival and death groups. The value of these indicators in determining the prognosis of patients was analyzed using subject operating characteristic (ROC) curves. Logistic regression was used to analyze the risk factors for death from severe pneumonia.
 Results: The differences were statistically significant (P<0.05) when comparing age and pneumonia typing between the two groups. There was no statistically significant difference between the two groups in terms of gender and total length of stay (P >0.05). There was no statistically significant difference in LDH and ApoA1 levels between male patients and female patients (P>0.05). The differences in LDH and ApoA1 levels were statistically significant (P<0.05) when comparing patients with severe pneumonia at different ages. The differences in LDH and ApoA1 levels between SCAP and SHAP patients were not statistically significant (P>0.05). LDH and ApoA1 levels were higher in patients with severe pneumonia with acute exacerbation of slow-onset lung or MODS during hospitalization than in patients with severe pneumonia without acute exacerbation of slow-onset lung or MODS, with statistically significant differences (P<0.05). The differences were statistically significant (P<0.05) when comparing LDH and ApoA1 levels in patients with severe pneumonia with different PSI grades or APACHE II scores. The differences were statistically significant (P<0.05) when comparing LDH and ApoA1 levels in patients with severe pneumonia with different ICU length of stay. There was no statistically significant difference in LDH and ApoA1 levels when comparing patients with severe pneumonia who required tracheal intubation or sedation and analgesia during hospitalization (P>0.05). LDH and ApoA1 levels in patients with severe pneumonia with different duration of mechanical ventilation were compared with statistically significant differences (P<0.05). LDH and ApoA1 levels in the death group were 105.08 (75.22 ~140.0), which was significantly higher than 86.66 (62.66 ~ 106.14) in the survival group, with statisti","PeriodicalId":16175,"journal":{"name":"Journal of Medical Biochemistry","volume":" 21","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135286390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to differences in race and genotype, MCV, MCH, HbA2 and other indicators are far from each other. The purpose of this study is to evaluate the common screening indicators of α, β and αβ-compound thalassemia carriers in Hunan Province, and try to use the relevant formulas in the existing literature to predict and distinguish different types of thalassemia carriers.&#x0D; Methods: Receiver operating characteristic curve (ROC curve) combined with Youden index was utilized to analyze results of blood routine examination, hemoglobin electrophoresis, and literature-related formulas for 1111 α-thalassemia carriers, 464 β-thalassemia carriers and 24 αβ-thalassemia carriers.&#x0D; Results: For α-thalassemia carriers, no matter which screening index or formula, the screening efficiency was not ideal. For β-thalassemia minor carriers, RBC, RDW_CV, Hb_A2, Hb_F and formula 5-7 could be used, and for compound thalassemia, RBC, RDW_CV, Hb_A2 and formula 5-6 are suitable. Hb_A2 has high efficiency in the screening of β-thalassemia minor and αβ-thalassemia. For the screening of β-thalassemia minor, if the cut-off value of HbA2 is set to 3%, the detection rate of 93.32% can be obtained at the positive rate of 9.6%, and if it is set to 3.15%, the detection rate can also reach 81.68% at the positive rate of 2.89%. For αβ-thalassemia, if the cut-off value of HbA2 is set to 3%, the detection rate of 95.83% can be obtained under the positive rate of 8.08%.&#x0D; Conclusions: Different screening indicators and formulas have different efficiencies for different thalassemia carriers. α-thalassemia carriers are easily missed by screening indicators or corresponding formulas. HbA2 is a better screening indicator for both β-thalassemia minor carriers and αβ-thalassemia carriers, and formulas 5, 6, and 7 are suitable for β-thalassemia minor carriers, and formulas 5 and 6 are better for αβ-thalassemia carriers.

Currently used tumor markers are insufficient in diagnosing breast cancer. In this study, we aimed to investigate the relationship between serum levels of synaptophysin-like protein 1 (SYPL1) and BC, as well as compare SYPL1 with other blood tumor markers. Method: The study group consisted of 80 female patients with a histopathological diagnosis of invasive BC and didn’t receive any radiotherapy/chemotherapy. The control group 72 women with noprevious history of breast disease and evaluated as Breast Imaging Reporting and Data Systems (BI-RADS 1-2) on imaging. Serum SYPL1, cancer antigen 15-3 (CA 15-3) and carcinoembryonic antigen (CEA) were measured in both groups. Results: The diagnostic values of SYPL1, CEA and CA15-3 proteins in diagnosing BC were statistically significant. The sensitivity of SYPL1 was 48.75%, with a specificity of 80.56%. CA15-3 had a sensitivity of 80% and a specificity of 49.30%. There wasn’t statistically significant correlation between serum SYPL1 and tumor diameter, lymph node metastasis, distant organ metastasis, and stage. &#x0D; Conclusion: The serum SYPL1 maintained a higher discriminatory ability for BC. The serum SYPL1 level can be used with high specificity in the diagnosis of BC.

The expressions of MIR155HG and TNF-α were detected via quantitative reverse transcription-polymerase chain reaction (qRT-PCR), the incidence of complications during treatment was observed, and the associations of MIR155HG and TNF-α with SLEDAI before treatment and complications were analyzed. All patients were followed up after discharge, and the related factors to the prognosis of patients were analyzed via Cox regression analysis.&#x0D; Results: The levels of MIR155HG and TNF-α were higher in patients with an SLEDAI score of 10-14 points than those in patients with an SLEDAI score of 5-9 points and 0-4 points. MIR155HG and TNF-α were positively correlated with the incidence of infection, renal damage and cardiac damage. Moreover, there was also a positive correlation between the expressions of serum MIR155HG and TNF-α in SLE patients. SLEDAI score ≥10 points, complications during hospitalization, and highly-expressed MIR155HG and TNF-α were risk factors related to the prognosis of patients.&#x0D; Conclusion: MIR155HG and TNF-α are key regulators in the pathogenesis of SLE, and they can affect the prognosis of patients.
