[Objective] To explore how to deal with the paternity test of complex adoption cases. [Method] Samples from 13 families, in which adoptive parents were suspected related to biological parents, were genotyped using "Identifder + Sinofder + Powerplex 16" combined system (D8S1179, D21S11, D7S820, CSFIPO, D3S1358, TH01, D13S317, D16S539, D2S1338, D19S433, VWA, TPOX, D18S51, D5S818, FGA, D6S1043, D12S391, PentaD, PentaE) followed by further statistical analysis. [Result] Among all 13 cases, 2 were completely accordance with the Mendel law, PI > 10 000. There found more than 3 inconsistent loci in 8 cases. And found 1～2 inconsistent loci in 3 cases, needed to test more STR loci until PI≥10 000. The half sibling index (HSI) was also calculated with ITO method. The adoptive parents of 2 cases were not excluded from a full sibling with biological parents. In addition, Y-STR loci were tested for 4 cases (father/son). Two adoptive fathers of them were not excluded from the paternal relationship with biological fathers. [Conclusion] The most (76.9%) of all (13) complex adoptive cases of paternity test could be drawn a definite conclusion with combined system of "Identifder + Sinefiler + Powerplexl6". Minority (23.1%) of them was not definite yet and needed testing more STIR loci. Meanwhile, we suggested adding Y-STR tests and providing HSI for reference.

Objective:To investigate the distribution and influencing factors of the ocular biological parameters related to refractive development in school-age children.Methods:A cross-sectional study was performed.A total of 1 091 children aged 6-12 years old from July, 2017 to August, 2018, resident in downtown of Zhenjiang were enrolled in this study.The corneal radius of curvature (CR) and axial length/corneal radius of curvature ratio (AL/CR) were calculated after AL and corneal curvature (K) were measured by IOL Master.After pupillary dilatation with 0.5% tropicamide, cycloplegic retinoscopy was performed to identify refractive status.According to the spherical equivalent refraction (SER), all right eyes were classified into myopia, hyperopia and emmetropia.The comparison of the above parameters between different genders, as well as among different age groups and different refractive status groups were determined while the relative factors of the biological parameters and refractive status were analyzed by multivariate regression analysis.The study protocol was approved by the Ethics Committee of Affiliated People's Hospital of Jiangsu University (No.K-20190153-W).Results:There were statistical differences in AL, SER and AL/CR value among different age groups ( F=32.34, P<0.01; F=33.69, P<0.01; F=2.19, P=0.04), which showed that refractive status shifted to myopia as well as AL and AL/CR value were increased with age.Compared with the girls, the boys had significantly longer AL, greater CR, greater AL/CR value, and smaller K ( t=7.58, P<0.01; t=-7.48, P<0.01; t=-8.08, P<0.01; t=-2.14, P=0.03). There were statistical differences in AL and AL/CR value among different refractive status groups ( F=192.68, P<0.01; F=143.15, P<0.01). The myopia group had longer AL and greater AL/CR value than the other two groups.Children whose parents were not myopic and children who had outdoor activities more than 14 hours per week and did homework less than 20 hours per week and children who slept more than 9 hours per day had shorter AL, smaller AL/CR value, and were more inclined to hyperopia or emmetropia.The results of multivariate regression analysis suggested that children aged from 6-12 years old with older age, female, increased height, parental myopia, and more time in homework or less time in outdoor activities per week may be more likely to have myopia, and longer AL or bigger AL/CR value was correlated with older age, male, greater body mass index (BMI), increased height, myopia conditions of parents, more time of doing homework, and less time in outdoor activities. Conclusions:The SER shifts to myopia with age in 6 to 12-year-old school-age children in the downtown of Zhenjiang.And there are significant differences in AL, CR and AL/CR value between boys and girls.Female, older age, increased height, more time in homework, less time in outdoor activities, and parental myopia are associated with more negative SER.

Aim To investigate the serum levels of thrombin-antithrombin complex(TAT),tissue type plas-minogen activator-inhibitor complex(t-PAIC)and thrombomodulin(TM)in patients with intracranial atherosclerotic steno-sis(ICAS),and their correlations with the degree of stenosis.Methods A total of 196 ICAS patients(ICAS group)who underwent treatment in Cangzhou People's Hospital from January 2021 to February 2023 were enrolled as research sub-jects.Based on the degree of vascular stenosis,they were separated into three groups:mild group(n=78),moderate group(n.=64),and severe group(n=54).A group of 196 healthy outpatient with similar clinical basic data to ICAS patients was selected as controls.The serum levels of TAT,t-PAIC,and TM in each group were compared;Spearman method was applied to analyze the correlation between serum levels of TAT,t-PAIC,TM and stenosis severity in ICAS pa-tients;Multivariate Logistic regression was applied to analyze the influencing factors of severe stenosis in ICAS patients;ROC curve was applied to analyze the predictive value of serum TAT,t-PAIC,TM and total cholesterol(TC)levels for se-vere stenosis in ICAS patients.Results Compared with the control group,the serum levels of TAT,t-PAIC,and TM were significantly increased in the ICAS group(P＜0.05);the levels of serum TAT,t-PAIC,TM,and TC in the mild,moderate,and severe groups increased accordingly(P＜0.05).Spearman analysis showed that the serum levels of TAT,t-PAIC,and TM in ICAS patients were positively correlated with the degree of stenosis(r=0.574,0.695,0.628;all P＜0.05).Multivariate Logistic regression analysis showed that TAT,t-PAIC,TM,and TC were independent risk factors for severe stenosis in ICAS patients(P＜0.05).The ROC curve showed that the AUC of severe stenosis in ICAS patients predicted by combination of TAT,t-PAIC,TM,and TC was 0.927,with a sensitivity of 83.33％and a specificity of 86.62％,which was superior to the independent prediction of TAT,t-PAIC,TM and TC(Zcombined detection-TAT=4.617,Zcombined deteetion-t-PAIC=4.024,Zcombined detection-TM=4.004,Zcombined detection-TC=7.078,all P=0.000).Conclusion The ser-um levels of TAT,t-PAIC,and TM in the ICAS group were significantly increased,and were positively correlated with the severity of stenosis.The combination of the three and TC has a high predictive value for the occurrence of severe stenosis in ICAS patients.

Objective:To establish and validate the prediction model for bone marrow metastasis (BMM) in malignant tumors by screening out laboratory multiparameters.Methods:This case-control study collected 444 cases of malignant tumor patients who were hospitalized in the First Hospital of Jilin University from March 2018 to March 2024, including 243 cases for model establishment set and 201 cases for model validation set. The model establishment set was divided into BMM positive group (81 cases) and BMM negative group (162 cases), and the model validation set was divided into positive group (67 cases) and a negative group (134 cases). We collected patients′ clinical information such as gender, age, clinical diagnosis, and results of 47 laboratory tests including routine blood analysis, coagulation, liver function, tumor markers, potassium, sodium, chloride, and calcium ion tests, bone marrow morphology, and bone marrow biopsy. BMM was taken as the outcome event, differencial variables were analyzed using inter group comparisons, the correlation among parameters was analyzed using Pearson correlation analysis, the risk factors for BMM were analyzed using multivariate conditional logistic regression analysis, to establish logistic model, followed by efficiency evaluation on BMM predictive model using receiver operating characteristic (ROC) curves.Results:In the model establishment set, Pearson correlation analysis of 28 parameters that differed between the BMM positive and negative groups revealed that the correlation coefficients of 17 parameters, including mean platelet volume (MPV), hematocrit (HCT), hemoglobin (HGB), and prothrombin time (PT), were no more than 0.6 ( P<0.05). Further multivariate conditional logistic regression analysis demonstrated that MPV, HGB, HCT, PT, red cell distribution width (RDW), platelet count (PLT), alkaline phosphatase (ALP), chloride (Cl -), and mean erythrocyte hemoglobin concentration (MCHC) were the risk factors of BMM occurence in malignancy [MPV ( OR=9.929, 95% CI 2.688-71.335), HCT ( OR=8.232, 95% CI 6.223-9.841), HGB ( OR=4.300, 95% CI 1.947-16.577), PT ( OR=3.738, 95% CI 1.359-11.666), RDW ( OR=1.995, 95% CI 1.275-3.807), ALP ( OR=1.025, 95% CI 1.012-1.045), PLT ( OR=1.014, 95% CI 1.002-1.031), MCHC ( OR=0.724, 95% CI 0.523-0.880) and Cl -( OR=0.703, 95% CI 0.472-0.967)]. In the model establishment set, combiation of risk factors provided an AUC of 0.943 (95% CI 0.898-0.987, P<0.001), a sensitivity of 86.3%, and a specificity of 89.2% for BMM prediction. In the model validation set, the AUC was 0.924 (95% CI 0.854-0.960, P<0.001), with a sensitivity and specificity of 86.7% and 83.8%, respectively. Conclusion:This study built and validated a multiple-parameter model for BMM, which may facilitate the timely detection of BMM and provide reference for decision making of bone marrow aspiration.

Objective:To evaluate the clinical application of urine sediment score (USS) in early diagnosis, etiological differentiation, staging and prognosis of acute kidney injury (AKI), and to investigate the diagnostic efficacy of independent USS and its combination with blood urea nitrogen(Bun) serum creatinine(sCr) and uric acid(UA) in AKI.Methods:From August 23 to September 28, 2023, 9 020 morning urine samples of hospitalized patients in the First Hospital of Jilin University were detected by Sysmex UF5000.A total of 3 226 ssamples with small and round cell (SRC) > 1/μl and/or CAST>1/μl were screened for microscopic examination, and 404 cases with positive renal tubular epithelial cells and/or cast were enrolled in this study. There were 218 males and 186 females, aged 59.5 (49.0, 71.0) years. The 404 cases were divided into the USS AKI group (345 cases) and the USS non-AKI group (59 cases) according to the USS results based on the microscopic findings. According to Kidney Disease: Improving Global Outcomes (KDIGO) criteria, they were divided into KDIGO criteria AKI group (63 cases) and KDIGO criteria non-AKI group (341 cases), and the AKI group was divided into renal AKI group (33 cases) and non-renal AKI group (30 cases). According to the clinical diagnosis recorded in the medical records, they were divided into clinically diagnosed AKI group (29 cases) and clinically diagnosed non-AKI group (375 cases).The χ 2 test or Fisher exact test was used to compare USS in different AKI causes and stages. Logistic regression was used to calculate the odds ratio of renal AKI and stage 3 AKI. The area under the receiver operating characteristic curve was used to evaluate the sensitivity and specificity of USS, sCr, UA and Bun alone and in combination in the diagnosis of AKI, and the best cut-off value, sensitivity and specificity in the diagnosis of AKI were calculated. P < 0.05 was considered statistically significant. Results:The USS was used to identify the etiology of KDIGO standard AKI group,and there were significant differences in USS between renal AKI group and non-renal AKI group (χ 2=11.070, P<0.001). Compared to USS=1, the odds ratio of renal AKI was 8.125 when USS≥2 (95% CI 2.208—29.901). There was a statistically significant difference in the comparison of USS between groups in each stage of the AKI staging study based on USS (χ 2=15.724, P<0.05). Compared to USS=1, the odds ratio of stage 3 AKI was 9.714 when USS≥2 (95% CI 1.145-82.390). The AUC of independent USS in the diagnosis of AKI was 0.687 (95% CI 0.618-0.757, P<0.001), the specificity was 65.7% and the sensitivity was 61.9%. The AUC of USS combined with Bun, sCr, UA in the diagnosis of AKI was 0.794 (95% CI 0.608-0.980, P<0.05), the specificity was 82.4%, and the sensitivity was 88.9%. Conclusions:There wasan increased likelihood of renal AKI or stage 3 AKI while USS≥2,and whose combination with Bun, sCr and UA will improve the diagnostic efficiency of AKI.
