Objective To verify the association between admission serum phosphate level and short-term (<30 days) mortality of severe pneumonia patients admitted to intensive care unit (ICU) / respiratory intensive care unit (RICU). Methods Severe pneumonia patients admitted to the ICU/RICU of Quanzhou First Hospital Affiliated to Fujian Medical University from November 2019 to September 2021 were included in the study. Serum phosphate was demonstrated as an independent risk factor for short-term mortality of severe pneumonia patients admitted to ICU/RICU by logical analysis and receiver operator characteristic (ROC) curve. The patients were further categorized by serum phosphate concentration to explore the relationship between serum phosphate level and short-term mortality. Results Comparison of baseline indicators at admission between the survival group (n=54) and the non survival group (n=46) revealed that there was significant difference in serum phosphate level [0.9 (0.8, 1.2) mmol/L vs. 1.2 (0.9, 1.5) mmol/L, P<0.05]. Logical analysis showed serum phosphate was an independent risk factor for short-term mortality. ROC curve showed that the prediction ability of serum phosphate was close to pneumonia severity index (PSI). After combining serum phosphate with PSI score, CURB65 score, and sequential organ failure score, the predictive ability of these scores for short-term mortality was improved. Compared with the normophosphatemia group, hyperphosphatemia was found be with significantly higher short-term mortality (85.7% vs. 47.3%, P<0.05), which is absent in hypophosphatemia (25.8%). Conclusions Serum phosphate at admission has a good predictive value on short-term mortality in severe pneumonia patients admitted to the ICU/RICU. Hyperphosphatemia at admission is associated with a higher risk of short-term death.

Objective The aim is to sort CD90+ subpopulation cells in human liver cancer cell lines and investigate efficiency of magnetic cell sorting (MACS) on sorting the liver cancer stem cells. Methods ①Expressions of CD90. Immunohistochemical method was used to determine the expressions of CD90 in normal liver tissues in 8 cases, liver cancer and adjacent liver cancer tissues in 58 cases. ②Screened the cell lines. Huh-7, MHCC97-H, Bel-7402, and SMMC-7721 cell lines were divided into blank control group and experimental group (5.5×105 cells per hole, 1 hole), cells of the experimental group were added with 5 μL CD90–PE while cells of the blank control group were treated with 5 μL CD90–PE non fluorescent antibody. Determined the proportion of CD90+ cells in the 2 groups by flow cytometry (FCM). ③MACS. Huh-7 and MHCC97-H cell lines were labeled with magnetic beads respectively and sorted by MACS, 1 mL cell suspensionsorted by magnetic sorting (MS) was collected as CD90– group, and 1 mL PBS after MS wash was collected as CD90+ group, as well as blank control group and experimental group. Determined the proportion of CD90+ cells in 4 groups by FCM. Two times of MACS were performed in Huh-7 cells. ④Serum free culture and serum culture. Huh-7 cells were divided into serum-free culture group and serum culture group (1 hole), and proportions of CD90+ cells were determined by FCM at 1 week after culture. Results ①The positive rate of CD90 was 0 (0/8), 65.5% (38/58), and 20.7% (12/58) in normal liver tissues, liver cancer tissues, and adjacent liver cancer tissues respectively, and the positive rate of CD90 was higher in liver cancer tissues than those of normal liver tissues (χ2=6.78, P<0.05) and adjacent liver cancer tissues (χ2=20.83, P<0.05). ②For Huh-7, MHCC97-H, SMMC-7721, and Bel7402 cell lines, the proportions of CD90+ cells in the experimental group was 0.851%, 1.090%, 2.710%, and 4.050% respectively, the proportions of CD90+ cells in the blank control group was 0.241%, 0.688%, 1.890%, and 2.080% respectively, so we chose Huh-7 and MHCC97-H cell lines to perform MACS. ③Results of MACS for Huh-7 cell line. For the first MACS, the proportions of CD90+ cells in the blank control group, experimental group, CD90– group, and CD90+ group was 0.241%, 0.851%, 0.574%, and 1.100% respectively. For the second MACS, the proportions of CD90+ cells in the blank control group, experimental group, CD90– group, and CD90+ group was 0.032%, 0.961%, 0.426%, and 9.700% respectively. Conclusions The normal liver tissues do not express the CD90, but the liver cancer tissues express CD90 highly. There is a few CD90+ cells in Huh-7 and MHCC97-H liver cancer cell lines. The MACS has a certain effect on improving the proportion of CD90+ cells in the cell lines. The serum-free suspension culture has no effect on enriching CD90+ cells.
Objectives To investigate the correlation between blood total cholesterol (TC) and prognosis of idiopathic sudden sensorineural hearing loss (ISSNHL) and to provide references for clinical treatment and prognosis assessment. Methods We included 232 ISSNHL patients with total deafness in Wenzhou Central Hospital from June 2015 to March 2017 using a prospective cohort design. Recording information including age, gender, hypertension, diabetes mellitus, vertigo, level of blood total cholesterol (TC), level of triglyceride (TG), level of low-density lipoprotein (LDL-C) and LDL/HDL ratio (LDL-C/HDL-C) were collected. Correlation between the prognosis of ISSNHL and blood total cholesterol were analyzed by univariable and multivariable logistic regression analysis. Results The clinical effective rate of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L was higher than that of patients with TC lower than 5.2 mmol/L (univariable: RR=6.49, 95%CI 3.16 to 13.30, P<0.001; multivariable-adjusted covariates: RR=6.15, 95%CI 2.66 to 14.3,P<0.001) with significant difference. No significant difference was found between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (univariable: RR=1.02, 95%CI 0.52 to 2.00,P=0.960; multivariable-adjusted covariates: RR=1.61, 95%CI 0.55 to 4.73, P=0.386). Gender-specific analysis showed for both male and female groups, the effective rates of patients with TC ranging from 5.2 mmol/L to 6.2 mmol/L were significantly higher than those of patients with TC lower than 5.2 mmol/L. There was no significant difference between patients with TC lower than 5.2 mmol/L and patients with TC higher than 6.2 mmol/L (P>0.05) in either male group or female group. Conclusion The current study suggests that patients with levels of TC ranging from 5.2 mmol/L to 6.2 mmol/L predicts the best prognosis.
ObjectiveTo investigate the association between serum thyroid hormone levels and prognosis for patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD) without thyroid disease, and explore the prognostic value of serum thyroid hormone levels for patients with AECOPD.MethodsThe clinical data of 239 hospitalized cases of AECOPD [149 males, 90 females, aged 42-92 (77.7±8.9) years] from January 2013 to November 2017 were retrospectively analyzed. Serum thyroid hormone levels including total tetraiodothyronin (TT4), total triiodothyronin (TT3), thyroid stimulating hormone (TSH), free tetraiodothyronin (FT4) and free triiodothyronin (FT3) were measured by chemiluminescence immunoassay. All patients were divided into a survival group and a death group according to the prognosis. Serum thyroid hormone levels were compared between two groups. Correlations of serum thyroid hormone levels with the occurrence of death in AECOPD patients were analyzed. The prognostic value of serum thyroid hormone levels for AECOPD patients was explored by receiveroperating characteristic (ROC) curve analysis. And the best cut-off value of serum thyroid hormone level in predicting the risk of death was calculated.ResultsSerum TT4, TT3, FT4 and FT3 levels in the survival group were significantly higher than those in the death group [TT4: (89.35±21.45) nmol/L vs. (76.84±21.33) nmol/L; TT3: (1.05±0.34) nmol/L vs. (0.72±0.19) nmol/L; FT4: (16.17±2.91) pmol/L vs. (14.45±2.85) pmol/L; FT3: (3.06±0.81) pmol/L vs. (2.24±0.72) pmol/L; all P<0.05]. The differences of serum TSH level between two groups were not statistically significant [0.98 (0.54-1.83)vs. 0.57 (0.31-1.84), P>0.05]. Spearman correlation analysis showed that serum TT4, TT3, FT4 and FT3 levels were significant correlated with the occurrence of death (r values were 0.226, 0.417, 0.220, 0.387, respectively, P<0.05). And there was no significant correlation between serum TSH level and the occurrence of death (P>0.05). ROC curve analysis was done between serum thyroid hormone levels (TT4, TT3, TSH, FT4 and FT3) and the occurrence of death in the AECOPD patients. The areas under ROC curve were 0.659, 0.793, 0.588, 0.655 and 0.772, respectively. Serum TT3 was the best indicator for predicting the occurrence of death. When serum TT3 level was 0.85nmol/L, the Youden index was the highest (0.486), with a sensitivity of 70.2%, and a specificity of 78.3%. It was the best cut-offl value of serum TT3 to predict the risk of death in AECOPD patients.ConculsionsSerum thyroid hormone levels are significant associated with the prognostic for AECOPD patients. There is certain value of serum thyroid hormone levels in prognostic evaluation of AECOPD patients.
Prostate cancer is a common disease in the USA and Europe, with a gradually increasing incidence in China, and presents a significant health burden for older men. The lack of modifiable risk factors has made early detection as a strategy to reduce mortality. Current methods of screening involve the measurement of serum prostate-specific antigen (PSA) and digital rectal examination followed by biopsy. With PSA screening evidence of level I absent, the evidence on the use of PSA as a screening test is still highly controversial. Furthermore, there is controversy over whether screen-detected lesions will become clinically significant. There are three major treatment options for localized disease: radical prostatectomy, radical radiotherapy and monitoring with treatment if required. There is no evidence of randomized controlled trial (RCT) to suggest a survival advantage of any of these treatments. Opinions about the related benefits and risks of screening vary widely. In the absence of RCT of benefit for screening, many now suggest “informed consensus” screening, which encourages a discussion between the patient and his physician with both sides informed of all of the issues.
