Objective To compose and evaluate the measurement uncertainty of two kinds of chemiluminescence detection system using different methods.Methods The measurement uncertainty was composed by 4 different methods:(1) U 1％ was composed of within-run CV(CVw ％),between-run CV(CVB ％)and bias (CVBias ％);(2) U2％ was composed of CVB ％ and uncertainty of calibration (CVcal ％);(3) U3％ was composed of CVW％,CVs％ and CVcal％;(4) U4％ was composed of CVW％,CVB％,CVBias％ and CVcal％.The measurement uncertainty of Architect i2000SR system (Abbott,USA) and DXI800 system (Beckman,USA) was assessed.Pearson correlation analysis,Spearman correlation analysis,Paried t test and Mann-Whitney u test were performed to analyze the data.Results For Architect i2000SR system,U1％,U2％,U3％ and U4％ were significantly correlated (r=0.727-0.988,all P＜0.05),U3％ and U2％ were significantly different (t =6.88,P＜0.05),U4％ and U1％ were significantly different (t =6.21,P＜0.05).For DXI800 system,U1％,U2％,U3％ and U4％ were also significantly correlated (r =0.608-0.975,all P＜0.05),no significant difference was found between U3％ and U2％ (z=-1.33,P＞0.05),or between U4％ and U 1％ (z =-1.04,P＞ 0.05);the expanded measurement uncertainty was correlated with CVW％,CVB％,CVBias％(rs=0.653-0.912,all P＜0.05),but not with CVcal％(rs=0.548,P＞0.05).Conclusions For Architect i2000SR system,the fourth method is more proper to compose the measurement uncertainty (U4％).For DXI800 system,the first method is more appropriate (U1％).According to the contribution of different components to the measurement uncertainty,the measurement quality could be improved by reducing the imprecision and bias.

Objective:To see the influence of different antiplatelet therapies on stroke patients’ readmission by performing a deep data-mining into Beijing Healthcare Insuring Database,based on a large sample size.Methods:Aretrospective cohort study,was adopted to extract patients primarily diag-nosed as ischemic stroke from healthcare database.The first hospital records were considered as the pa-tient’s baseline in this study,who were divided into MAPT (aspirin)and DAPT (aspirin and clopi-dogrel)according to the patient’s baseline medications.A follow-up was conducted to see whether the patients would have rehospitalization record because of major result events after medication.The major re-sult events,included:(1 )recurrence of ischemic stroke;(2)hemorrhagic transformation of ischemic stroke;(3)myocardial infarction;(4)the digestive hemorrhage.The Kaplan-Meier figure was used to compare the survival situations between these two groups,the log-rank test was used to test the difference of the survival curve,and 1 ∶1 propensity score matching was calculated from the patients’baseline da-ta.Cox proportional hazards model was used to calculate the hazard ratio (HR).Results:A total of 27 695 patients From January 201 0 to September 201 3 were included,4 047 with DAPT,and 23 648 with MAPT.Because the baseline characteristics of the patients was disequilibrium,so we used 1 ∶1 pro-pensity score matching,after which,the number of the two groups was 4 046 each.Adjusted for the gen-eral demographic characteristics such as age,sex,nationality,complication and drug combination,no statistical significance was observed between the survival curves of the two groups (P =0.06).HR value of major result events between the groups was 0.91 (0.82 -1 .01 ,P =0.07),which was not statistically significant.The covariate gender HR =1 .36 (1 .20 -1 .55,P <0.05),accompanied by diabetes HR =1 .36 (1 .20 -1 .54,P <0.05 ),dyslipidemia HR =1 .1 3 (1 .00 -1 .27,P =1 .1 3),heart disease HR =1 .39 (1 .22 -1 .58,P <0.05)was statistically significant.Drug combination with other antiplate-let agents HR =1 .05 (0.95 -1 .1 7,P >1 .05)did not increase the risk of readmission.Conclusion:There was no difference in prevention of readmission between patients with DAPT and MAPT.Patients with complications should actively treat the complications at the same time as they prevent recurrence after first attack.

Objective:To investigate the relationship and diagnostic value of serum hepatitis B virus(HBV) RNA on liver significant inflammation in chronic hepatitis B (CHB)patients with normal or mildly elevated alanine transaminase (ALT) levels.Methods:A total of 211 treatment-naive CHB patients with ALT

Objective:To investigate the clinical, imaging, etiological and prognostic features of patients with infarctions in different locations of the medulla oblongata.Methods:Patients with acute medullary infarction hospitalized at Tianjin Huanhu Hospital from July 2017 to July 2022 were included. The risk factors, clinical manifestation, stroke mechanism and 90-day prognosis of these patients were analyzed retrospectively.Results:Among the 256 patients enrolled, 150 (58.6%) had lateral medullary infarction (LMI), 106 (41.4%) had medial medullary infarction (MMI). The most frequent clinical manifestation of patients with LMI was dizziness (84.7%,127/150). And motor disorders (83.0%,88/106) was the most frequent clinical manifestation of patients with MMI. LMI lesions were mostly located in the middle (42.7%,64/150) and MMI lesions were mostly located in the upper (60.4%,64/106) medulla oblongata, with statistically significant difference (χ 2=47.53, P<0.001). Large artery atherosclerosis (LAA) was the main stroke mechanism in LMI and MMI [57.3%(86/150) vs 56.6%(60/106)]. Early neurological deterioration was more common in MMI (25.5%,27/106) and less common in LMI (7.3%,11/150), with statistically significant difference (χ 2=16.17, P<0.001). At discharge, more patients with MMI showed poor prognosis in short term [45.3% (48/106) vs 24.0% (36/150), with statistically significant difference (χ 2=12.76, P<0.001)] and even long term at 90-day follow-up [33.0% (35/106) vs 12.7% (19/150), also with statistically significant difference (χ 2=15.48, P<0.001)] than those with LMI. A total of 10 patients (4.0%, 10/256) developed respiratory failure during hospitalization, including 7 patients with LMI (4.7%, 7/150) and 3 patients with bilateral MMI (2.8%,3/106). Early neurological deterioration ( OR=3.38, 95% CI 1.25-9.10, P=0.016) and LAA (compared with small artery occlusion) ( OR=3.08, 95% CI 1.13-8.37, P=0.028) were independent risk factors for poor prognosis in MMI. Age ( OR=1.01, 95% CI 1.01-1.17, P=0.026) and early neurological deterioration ( OR=20.19, 95% CI=2.63-155.06, P=0.004) were independently correlated with poor outcome in LMI. Conclusions:LMI and MMI had similar etiology and significant differences in clinical manifestations, early neurological deterioration and prognosis. Further classification of medullary infarction was of great significance for diagnosis, treatment and prognosis evaluation.

Objective To investigate the expression levels of serum high-mobility group box 1(HMGB1),soluble CD163(sCD163),and prostaglandin E2(PGE2)in patients with hepatitis B virus-related chronic-on-acute liver failure(HBV-ACLF),and to evaluate the value of the three indicators used alone or in combination in predicting prognosis.Methods A total of 76 patients with HBV-ACLF who were hospitalized in Department of Infectious Diseases,The First Affiliated Hospital of Xinxiang Medical University,from July 1,2022 to September 30,2023 were enrolled,and according to the 28-day prognosis,they were divided into survival group with 48 patients and death group with 28 patients.General data were collected,Model for End-Stage Liver Disease(MELD)score was calculated,and ELISA was used to measure the serum levels of HMGB1,sCD163,and PGE2.The independent-samples t test was used for comparison of normally distributed continuous data between two groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups;the chi-square test was used for comparison of categorical data between two groups.The Spearman rank correlation test was used to analyze the correlation of HMGB1,sCD163,and PGE2 with MELD score;the receiver operating characteristic(ROC)curve was used to analyze the value of HMGB1,sCD163,and PGE2 used alone or in combination in predicting the prognosis of HBV-ACLF patients.Results There were significant differences between the two groups in total bilirubin,white blood cell count,the percentage of neutrophils,procalcitonin,serum amyloid A,interleukin-6,serum sodium,and serum creatinine(all P＜0.05).Compared with the survival group,the death group had significantly higher serum levels of HMGB1(Z=-2.997,P=0.003)and sCD163(Z=-2.972,P=0.003),a significantly higher MELD score(t=-6.997,P＜0.001),and a significantly lower serum level of PGE2(Z=-4.909,P＜0.001).The Spearman rank correlation test showed that HMGB1 and sCD163 were positively correlated with MELD score(r=0.431 and 0.319,both P＜0.05),while PGE2 was negatively correlated with MELD score(r=-0.412,P＜0.05).The ROC curve analysis showed that HMGB1,sCD163,and PGE2 used alone had an area under the ROC curve(AUC)of 0.717,0.716,and 0.856,respectively,while the combination of the three indicators had the highest predictive value,with an AUC of 0.930,a sensitivity of 0.778,and a specificity of 0.920.Conclusion Serum HMGB1,sCD163,and PGE2 used alone or in combination have a good reference value in predicting the prognosis of HBV-ACLF patients,and the combination of the three indicators has the highest predictive value,which holds promise for further observation and research.

Objective:To explore the prognostic influencing factors of adult lymphoma-associated hemophagocytic syndrome (LAHS) based on multicenter data.Methods:The clinical data of 86 LAHS patients diagnosed in 9 medical centers of Huaihai Lymphoma Working Group from January 2015 to August 2020 were retrospectively analyzed. The optimal cut-off value of continuous variables was obtained based on MaxStat algorithm. Cox proportional hazard regression model was used for univariate and multivariate analyses. Kaplan-Meier method was used for survival analysis, and log-rank test was performed.Results:Among the 86 adult LAHS patients, 50 (58.1%) were males and 36 (41.9%) were females, the median age of the patients was 57 years old (19-76 years old), and the median overall survival (OS) time was 1.67 months (95% CI 0.09- 3.24 months). The most common pathologic type was diffuse large B-cell lymphoma (58 cases, 67.44%). Based on MaxStat algorithm, the optimal cut-off values of age, albumin, serum creatinine, lactate dehydrogenase, fibrinogen and platelet count were 64 years old, 30.1 g/L, 67 μmol/L, 1 045 U/L, 4.58 g/L and 72×10 9/L, respectively. Multivariate analysis showed that patient's age, lactate dehydrogenase, albumin and fibrinogen levels were independent influencing factors for OS (all P < 0.05). Conclusions:LAHS is dangerous and progresses quickly. Patients with age ≥ 64 years old, lactate dehydrogenase ≥ 1 045 U/L, fibrinogen ≥ 4.58 g/L and albumin < 30.1 g/L have poor survival.

OBJECTIVE: To investigate the expression and localization of metabotropic glutamate receptors 7 and 8 (mGluR7/8) in rat superior cervical ganglion (SCG) and their changes in response to chronic intermittent hypoxia (CIH). METHODS: We detected the expressions of mGluR7 and mGluR8 in the SCG of 8-week-old male SD rats using immunohistochemistry and characterized their distribution with immunofluorescence staining. The expression of mGluR7 and mGluR8 in the cytoplasm and nucleus was detected using Western blotting. A 6-week CIH rat model was established by exposure to intermittent hypoxia (6% oxygen for 30 s followed by normoxia for 4 min) for 8 h daily, and the changes in systolic blood pressure, diastolic blood pressure and mean arterial pressure were measured. The effect of CIH on expression levels of mGluR7 and mGluR8 in the SCG was analyzed using Western blotting. RESULTS: Positive expressions of mGluR7 and mGluR8 were detected in rat SCG. mGluR7 was distributed in the neurons and small fluorescent (SIF) cells with positive staining in both the cytoplasm and nuclei, but not expressed in satellite glial cells (SGCs), nerve fibers or blood vessels; mGluR8 was localized in the cytoplasm of neurons and SIF cells, but not expressed in SGCs, nerve fibers, or blood vessels. Western blotting of the nuclear and cytoplasmic fractions of rat SCG further confirmed that mGluR7 was expressed in both the cytoplasm and the nucleus, while mGluR8 exists only in the cytoplasm. Exposure to CIH significantly increased systolic blood pressure, diastolic blood pressure and mean arterial pressure of the rats (all P < 0.001) and augmented the protein expressions of mGluR7 and mGluR8 in the SCG (P < 0.05). CONCLUSION mGluR7 and mGluR8 are present in rat SCG but with different localization patterns. CIH increases blood pressure of rats and enhanced protein expressions of mGluR7 and mGluR8 in rat SCG.

Objective:To explore the prognostic value of lymphocyte subsets in adult hemophagocytic syndrome (HPS).Methods:A total of 172 adult HPS patients diagnosed in 8 medical centers from January 2013 to August 2020 were selected for the study, of whom 87 were male (50.6%, 87/172), and 85 were female (49.4%, 85/172), with 68 survivors and 104 deaths. The clinical data were summarized, and variables such as lymphocyte subsets, immunoglobulin characteristics and fibrinogen were retrospectively analyzed, and the correlation between the mentioned variables and patient prognosis was analyzed. The optimal cut-off values of continuous variables were calculated by MaxStat, and the prognostic factors of HPS patients were screened based on the Cox proportional hazard regression model.Results:The median age of HPS patients was 56 (42, 66) years old, and the 5-year cumulative survival rate was 37.4% (37.4/100). The median age, platelet and albumin were 48 (27, 63) years, 84×10 9/L and 32.3 g/L in the survival group, and 59 years, 45.5×10 9/L, and 27.3 g/L in the death group, respectively. The differences between the two groups was statistically significant ( Z=?3.368, P=0.001; Z=?3.156, P=0.002; Z=?3.431, P=0.001). Patients with differentiated cluster 8+(CD8+)<11.1%, CD3+<64.9%, CD4+>51%, and CD4/CD8 ratio>2.18 had poor prognosis (χ 2=7.498, P=0.023; χ 2=4.169, P=0.041; χ 2=4.316, P=0.038; χ 2=9.372, P=0.002). Multivariable analysis showed that CD4/CD8 ratio, age, fibrinogen and hemoglobin were independent prognostic factors in HPS patients ( HR=2.435, P=0.027; HR=5.790, P<0.001; HR=0.432, P=0.018; HR=0.427, P=0.018). Conclusion:Peripheral blood lymphocyte subsets can be used to evaluate the prognosis of patients with HPS; CD4/CD8 ratio, age, fibrinogen, and hemoglobin are independent prognostic factors in HPS patients.

Objective:Factors influencing the prognosis of hemophagocytic lymphohistiocytosis (HLH) in adults were analyzed based on multicentric data.Methods:Clinical data of 124 adult patients with HLH diagnosed in eight medical centers in the Huaihai Lymphoma Working Group from March 2014 to July 2020 were collected. The optimal truncation value of continuous variables was obtained based on the Maxstat algorithm, X-Tile software, and restricted cubic spline. Cox proportional risk regression model was used to construct the adult HLH risk prediction model, and the visualization of the model was realized through the histogram. The bootstrap resampling method was used to verify the model, C-index and calibration curve was used to verify the histogram, and the prediction accuracy was checked. Kaplan-Meier analysis was used to calculate the survival rate and draw the survival curve. Furthermore, the differences between groups were tested by log-rank.Results:The median age of the 124 patients was 55 (18-84) years, including 61 (49.19%) males. The most common etiology was infection. Serum ferritin increased in 110 cases (88.71%) , hepatosplenomegaly in 57 cases (45.97%) . Of the 124 patients, 77 (62.10%) died, and the median survival time of the patients was 7.07 months. Univariate results showed that the prognosis of adult HLH was influenced by sex, age, fibrinogen, serum creatinine, alanine aminotransferase, and albumin ( P<0.05) . The results of multivariate analysis showed that gender, platelet, albumin, alanine aminotransferase, and treatment regimens were independent influencing factors for prognosis. Based on the above five risk factors, the prediction model of the histogram was established, and the C-index of the model was 0.739. Finally, the calibration chart showed good consistency between the observed and predicted values of HLH. Conclusion:The prognosis of the adult hemophagocytic syndrome is influenced by many factors. Gender, platelet, albumin, alanine aminotransferase, and treatment regimens are independent risk factors. Therefore, the established histogram provides a visual tool for clinicians to evaluate the prognosis of adult HLH.
