Backgroud At present, there is no unified standard for the detection of glufosinate ammonium and three metabolites in urine, which affects the accurate assessment of occupational exposure risk to a certain extent. It is of great significance to establish a rapid and effective inspection method to ensure occupational safety and public health. Objective To establish an ultra performance liquid chromatography-tandem mass spectrometry for simultaneous determination of glufosinate ammonium and three metabolites in urine. Methods The effects of dilution solvents and dilution ratios on the response values of glufosinate ammonium and three metabolites were compared, and the retention capacities of solid phase extraction columns for targets as well as the effects of chromatographic columns and mobile phase systems on chromatographic peaks were analyzed. Samples were quantified by matrix effect matching external standard method. Accuracy of the method was evaluated by recovery rate of standard addition, and precision of the method was evaluated by relative standard deviation of intra-day and inter-day measurements. Urine samples of 30 health individuals were collected to evaluate the application of the method. Results The urine samples were diluted with 0.2 mL water and 0.6 mL acetonitrile, purified by HLB solid phase extraction columns, and separated by Dikma Polyamino HILIC columns, and gradient elution was carried out with 0.5 mmol·L⁻¹ ammonium acetate and 0.1% ammonia water as mobile phase, which achieved a good peak shape and mass spectrum response. The linearities of the four target compounds were good in the range of 0.5-50 ng·mL⁻¹, and the correlation coefficients (r) were all greater than 0.998. The detection limits were 0.56-2.86 μg·L⁻¹, the quantification limits were 1.87-29.54 μg·L⁻¹, and the recovery rates of standard addition ranged from 75.0% to 103.6%, The relative standard deviations of intra-batch and inter-batch were from 2.5% to 8.1% and from 4.3% to 9.3% respectively. The method was applied to detect 30 urine samples of subjects, and no target was detected. Conclusion The method is simple, rapid, sensitive, and accurate. It is suitable for the determination of glufosinate ammonium and its metabolites in human urine without derivatization.

Objective:To analyze the predictive value of miR-155-5p, miR-16 and miR-129-5p on the efficacy of continuous renal replacement therapy (CRRT) in children with septic shock.Methods:A total of 179 children with severe sepsis admitted to Shanxi Provincial Children′s Hospital from January 2021 to January 2022 were selected, 89 children with septic shock were selected as group A, 90 children with non-septic shock were selected as group B, and 80 healthy children were selected as group C. The expressions of miR-155-5p, miR-16 and miR-129-5p were measured and compared. The patients in the group A were divided into the effective group and the ineffective group according to the curative effect of CRRT treatment. The expressions of miR-155-5p, miR-16 and miR-129-5p in the two groups were compared, and its predictive value for the efficacy of CRRT treatment was analyzed.Results:Compared with group C and group B, the expressions of miR-155-5p in group A was higher: 2.56 ± 0.98 vs. 1.41 ± 0.35, 0.53 ± 0.11; and the expressions of miR-16 and miR-129-5p were lower: 1.00 ± 0.27 vs. 2.23 ± 0.98, 3.38 ± 1.01; 0.65 ± 0.17 vs.1.39 ± 0.22, 2.25 ± 0.76, there were statistical differences ( P<0.05). The results of Logistic regression analysis showed that the sequential organ failure assessment(SOFA) scores, white blood cell count, C reactive protein, procalcitonin, interleukin-6, tumor necrosis factor-alpha , N-terminal B-type natriuretic peptide precursor and the expressions of miR-155-5p, miR-16, miR-129-5p were independent risk factors for the efficacy of CRRT treatment in the children with septic shock. The results of Pearson correlation analysis showed that miR-155-5p was negative correlation with miR-16 and miR-129-5p ( r = - 0.411, - 0.369, P<0.05); and miR-16 was positive correlation with miR-129-5p ( r = 0.444, P<0.05). The results of receiver operating characteristic curve showed that the combination of the three items had a higher predictive value for the efficacy of CRRT in children with septic shock ( P<0.05). Children with high expression of miR-155-5p and low expression of miR-16 and miR-129-5p had higher mortality ( P<0.05). Conclusions:The expressions of miR-155-5p, miR-16 and miR-129-5p are abnormally in children with septic shock and are related to the efficacy of CRRT, which can be used for early prediction of the efficacy of CRRT.

Objective: A prognostic risk model for lung adenocarcinoma patients was established based on the cancer genome atlas(TCGA) database to explore the prognostic performance of autophagy related gene risk model for lung adenocarcinoma patients and its correlation with immune microenvironment． Methods: Clinical information and transcriptome data of lung adenocarcinoma patients were downloaded and extracted from TCGA database，and 232 autophagy-related genes were screened from the human autophagy database．cox regression analysis was used to screen out four autophagy genes independently associated with prognosis．The prognostic prediction model of lung adenocarcinoma was constructed by risk score ，and the performance of prediction model was evaluated by ROC curve．The relationship between risk scores and tumor immune microenvironment was explored using ESTIMATE ( estimation of stromal and immune cells in malignant tumour tissues using expression data) and CIBERSORT algo- rithms. Results: Thirty differentially expressed autophagy-related genes were identified in lung adenocarcinoma， of which four autophagy genes (BIRC5，ERO1A，ITGB4，NLRC4 ) could predict the prognosis of the patients. Grouped by risk score，the Kaplan-Meier analysis demonstrated that the survival rate of high-risk group was signifi- cantly lower than that of low-risk group(P＜0. 000 1) ．The ROC curve proved the accuracy of the model in predic- ting the prognosis of lung adenocarcinoma ( AUC = 0. 757 ) ．The ESTIMATE and CIBERSORT analyses revealed that the risk scoring model was associated with multiple immune cells and immune infiltrates in the tumor microenvi- ronment． Conclusion Compared with clinical data，the autophagy gene prognostic risk model can better predict the prognosis of patients with lung adenocarcinoma．In the high-risk group，CD4 + memory quiescent cells can im- prove prognosis in lung adenocarcinoma patients.

Objective: To construct nomogram to predict the risk of bone metastasis in patients with non-small cell lung cancer(NSCLC). Methods: The clinical data of NSCLC patients diagnosed in the hospital were retrospectively analyzed, including the occurrence of bone metastasis, age, gender, pathological type, smoking status, PS score, TN stage, metastasis of other sites before bone metastasis, carcinoembryonic antigen(CEA) level, alpha fetoprotein(AFP) level, serum calcium(Ca2+), serum phosphorus(P), alkaline phosphatase(ALP) level, which were determined by univariate and multivariate logistic regression analysis. Receiver operating characteristic curve(ROC) and decision curve analysis were used, DCA was used to verify the accuracy and clinical benefit of the model, and nomogram was used to visualize the model. Results: Area under the ROC curve(AUC) showed that in the modeling group(n=138) and the validation group(n=92), the AUC value predicted by combined indicators(age, gender, pathological type, CEA, ALP)(modeling group=0.792, validation group=0.629) was higher than that predicted by single indicator. Conclusion The prediction model constructed in this study has good effect and can provide reference for clinical screening of high-risk patients with bone metastasis of NSCLC.

Objective:To investigate the normal reference values of spinal bone mineral density measured by quantitative computed tomography (QCT) and the differences of bone mineral density (BMD) in different regions of in Chinese adult males.Methods:Men who underwent low-dose CT lung scan for cancer screening in regions of Northeast, North, East, South, Central and Southwest of China from January 2018 to December 2019 were selected. And the lumbar vertebrae BMD values in the male subjects were measured by the QCT system (Mindways Software, Inc.). The mean BMD values and their decline rates were calculated at an age interval of 10 years, and the prevalence of osteoporosis was calculated according to the American College of Radiology spine QCT osteoporosis diagnostic criteria.Results:A total of 50 682 males with a mean age of (50.22±12.79) years (ranged 20 to 98 years) were included in this study. The peak BMD of (173.11±28.56) mg/cm 3 in the healthy Chinese adult male population appeared in the age group of 20 to 29 years and then declined with age. Before the age of 70 years, the BMD was relatively higher in males in South China, and it was lower in Central China and Southwest China, and it was intermediate in Northeast, North and East of China, with statistically significant differences. There was no significant differences in BMD in the males in the two age groups of 70 to 79 years and 80 and older among the regions in China. The overall decline rate of spinal BMD in Chinese males under QCT was about 46.92% over the lifetime, and it declined obviouslyin the 40-49 age group. The overall prevalence of osteoporosis in Chinese male population aged 50 years and above was approximately 11.42%, with the highest prevalence in Southwest China and Central China (14.72% and 13.87%, respectively) and the lowest in North China and South China (8.53% and 7.71%, respectively). Conclusions:A reference of lumbar spine BMD values for healthy males in China based on QCT is established. BMD values were highest in South China and Lowest in Central China.

Objective:To establish the normal reference value of lumbar bone mineral density (BMD) under quantitative CT (QCT) in Chinese healthy adult females and to explore the regional differences.Methods:Total of 35 431 healthy women who met the inclusion criteria of Chinese health quantitative CT big data program were selected in this study. The BMD of the central plane of L 1 and L 2 vertebrae was measured by Mindways′s QCT system, and the mean value was taken. One-way analysis of variance was used to compare the BMD differences of lumbar vertebrae in women of different ages and regions. The subjects were grouped by an age interval of 10 years, and the level of BMD in different regions of the same age group were compaired. Results:The peak BMD of Chinese healthy adult women appeared in the age group of 20-29 years (Northeast China(183.01±24.58) mg/cm 3, North China (188.93±24.80) mg/cm 3, East China (187.54±27.71) mg/cm 3, South China (186.22±33.72) mg/cm 3, Central China (176.33±24.91) mg/cm 3, Southwest China(182.25±28.00) mg/cm 3), and then it decreased with age. The level of BMD in different regions decreased with the age. Before the age of 70 years, BMD in Central and Southwest China was always at a low level((176.23±24.91) to (90.38±28.12) mg/cm 3, 182.25±28.00 to (88.55±25.68) mg/cm 3), lower than those in Northeast China ((183.01±24.58) to (99.69±27.85) mg/cm 3), North China ((188.93±24.80) to (95.89±26.12) mg/cm 3), East China ((187.54±27.71) to (95.65±27.86) mg/cm 3). After 70 years of age, BMD tended to be the same in different regions ( P>0.05). The BMD values in Central China and Southwest China were similar in the age group of 40-60 years ( P>0.05). The BMD values in the health adult femles in the age group of 60 years in different regions of Chinawere all lower than those of bone mass abnormality (all P<0.05). The detection rate of osteoporosis in females over 50 years was the highest in Southwest China (25.65%) and it was the lowest in North China (17.30%). Conclusions:This study establishes reference values of BMD under QCT in healthy Chinese women, which can be used as a reference basis for identifying women with low BMD who are at risk of osteoporosis. The BMD value is the lowest in Southwest China and the highest in South China.

Objective:To use quantitative computed tomography (QCT) technology to measure the bone mineral density of the spine of the Chinese healthy population, and to explore its correlation with hemoglobin and serum albumin.Methods:The data in this study came from the China Health Quantitative CT Big Data Project (China Biobank). The spine bone density was measured by using QCT Pro Image Analysis System and all cooperating centers used the European spine phantom (NO.145) for quality control. Total of 50 053 healthy persons who met the criteria for entry were selected as the research subjects. The subjects were divided into 7 groups according to age. The general data, spine bone density, serum albumin, hemoglobin of the subjects were collected. The single-factor analysis of variance, Pearson correlation analysis and multi-classification logistic regression model were applied to analyze the correlation between bone density and hemoglobin and serum albumin.Results:The bone mineral density of healthy people decreased with age ( P<0.05), and there were significant differences in hemoglobin, serum albumin and body mass index (BMI) among different age groups (all P<0.05). Linear correlation analysis showed that there were positive correlation between bone mineral density and hemoglobin in healthy males in different age groups ( r=0.086, 0.101, 0.076, 0.090, 0.072, 0.123, 0.100, all P<0.01). There were negative correlation between bone mineral density and hemoglobin in certain age groups in women (40-49 years group: r=-0.027; 70-79 yearsgroup: r=-0.077; both P<0.05). And corelation were found between bone mineral density and serum levels of albumin in certain age groups of healthy subjects (among men, 30-39 years group: r=-0.048; 40-49 years group, r=-0.027; 70-79 years group, r=-0.051; among women, 30-39 years group: r=-0.044; 40-49 years group, r=-0.042; 50-59 years group, r=-0.086; 70-79 years group, r=-0.070; all P<0.05). After adjusting for age and BMI, the multi-category logistic regression analysis showed that the hemoglobin level was protective factor of normal bone density ( OR=1.022, 95% CI:1.017-1.027) and decreased bone density ( OR=1.012, 95% CI:1.007-1.016) in healthy males, and the serum albumin was risk factor for normal bone density ( OR=0.926, 95% CI:0.905-0.948) and decreased bone density ( OR=1.006, 95% CI:0.951-1.011) in healthy women. Conclusion:There is a correlation between bone mineral density and hemoglobin and serum albumin in Chinese healthy population. Hemoglobin is a protective factor for bone mineral density in men, and serum albumin is a risk factor for bone mineral densityin women.

Cerebrovascular disease is a common disease that seriously endangers the health of Chinese people. White matter hyperintensities (WMHs) are the most common in elderly patients. Intravenous thrombolysis is currently the most effective drug treatment for acute ischemic stroke. Hemorrhagic transformation (HT) is the most common serious complication after intravenous thrombolysis in patients with acute ischemic stroke. The destruction of blood-brain barrier in patients of WMHs can increase the risk of HT after intravenous thrombolysis. Matrix metalloproteinases and S100B jointly participate in the destruction process of blood-brain barrier in WMHs and HT after intravenous thrombolysis. At present, the pathogenesis of WHM and HT is not completely clear, and whether mild and moderate WMHs will aggravate HT is still controversial. Nevertheless, WMHs are still the independent risk factor for HT.
