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.

Objective To explore the relationships of serum Sestrin2 and Fetuin-A with disease outcome in patients with severe pulmonary tuberculosis. Methods A total of 108 patients with severe pulmonary tuberculosis admitted to our hospital from December 2020 to December 2022 were selected as study objects. Serum Sestrin2 and Fetuin-A levels were determined by enzyme-linked immunosorbent assay. According to 30 d disease outcomes, the patients in the study group were divided into death-disease group (22 cases) and survival group (86 cases). Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to analyze the predictive value of serum Sestrin2 and Fetuin-A levels in patients with severe pulmonary tuberculosis. The influencing factors of prognosis in patients with severe pulmonary tuberculosis were explored by multivariate Logistic regression. Results The serum Fetuin-A level in the survival group was higher than that in the death group, and the serum Sestrin2 level was lower than that in the death group (P < 0.05). The AUC (95%CI) of serum Sestrin2 and Fetuin-A were 0.752 (0.712 to 0.797) and 0.887 (0.842 to 0.937), respectively, with truncation values of 12.39 ng/mL and 350.67 μg/mL, the specificity of 55.64% and 65.57%, and the sensitivity of 92.73% and 92.73%. The AUC of the combined diagnosis was 0.920 (0.875 to 0.970), the specificity was 86.06%, and the sensitivity was 88.21%. The proportion of diabetes history in the death group was higher than that in the survival group, and peak expiratory flow (PEF), maximum mid-expiratory flow (MMEF), forced expiratory volume in the first second (FEV₁) and left ventricular ejection fraction (LVEF) were lower than those in the survival group(P < 0.05). Multiple Logistic regression analysis showed that LVEF≤50.00% (OR=3.777, 95%CI, 1.393 to 10.243), Fetuin-A < 350.67 μg/mL (OR=3.031, 95%CI, 1.943 to 4.730), Sestrin2≥12.39 ng/L (OR=5.709, 95%CI, 1.933 to 16.355) were the risk factors of the outcome of severe pulmonary tuberculosis(P < 0.05). Conclusion Serum Sestrin2 and Fetuin-A levels are closely related to the outcome of patients with severe pulmonary tuberculosis, and can be used as biological indicators to evaluate the outcome of severe pulmonary tuberculosis. The combined prediction has higher accuracy.

Background: Pseudorabies (PR), caused by the pseudorabies virus (PRV), is an endemic disease in some regions of China. Although there are many reports on epidemiological investigations into pseudorabies, information on PRV gI antibody dynamics in one pig farm is sparse. Objectives: To diagnose PR and analyze the course of PR eradication in one pig farm. Methods: Ten brains and 1,513 serum samples from different groups of pigs in a pig farm were collected to detect PRV gE gene and PRV gI antibody presence using real-time polymerase chain reaction and enzyme-linked immunosorbent assay, respectively. Results: The July 2015 results indicated that almost all brain samples were PRV gE gene positive, but PRV gI antibody results in the serum samples of the same piglets were all negative.In the boar herd, from October 2015 to July 2018 three positive individuals were culled in October 2015, and the negative status of the remaining boars was maintained in the following tests. In the sow herd, the PRV gI antibody positive rate was always more than 70% from October 2015 to October 2017; however, it decreased to 27% in January 2018 but increased to 40% and 52% in April and July 2018, respectively. The PRV gI antibody positive rate in 100-day pigs markedly decreased in October 2016 and was maintained at less than 30% in the following tests. For 150-day pigs, the PRV gI antibody positive rate decreased notably to 10% in April 2017 and maintained a negative status from July 2017. The positive trend of PRV gI antibody with an increase in pig age remarkably decreased in three tests in 2018. Conclusions The results indicate that serological testing is not sensitive in the early stage of a PRV infection and that gilt introduction is a risk factor for a PRV-negative pig farm. The data on PRV gI antibody dynamics can provide reference information for pig farms wanting to eradicate PR.

Objective:To investigate the expression and clinical significance of serum response factor (SRF) and myosin heavy chain 9 (MYH9) in esophageal squamous cell carcinoma(ESCC).Methods:The clinical data of 113 patients with esophageal squamous cell carcinoma treated in Tangshan people′s Hospital from January 2014 to December 2016 were retrospectively analyzed.Immunohistochemical staining was used to detect the expression of SRF and MYH9 in esophageal squamous cell carcinoma and corresponding adjacent tissues, and the correlation between the differential expression of SRF and MYH9 and clinicopathological features was analyzed.Results:Immunohistochemical staining showed that the positive expression rate of SRF in esophageal squamous cell carcinoma was 42.48% (48/113), which was significantly higher than that of 6.25% (2/32) in adjacent tissues (χ 2=14.487, P<0.05). The positive expression rate of MYH9 was 57.52% (65/113), which was significantly higher than that of 25.00% (8/32) in adjacent tissues (χ 2=10.551, P<0.05). The expression levels of SRF and MYH9 were closely related to the differentiation, lymph node metastasis and TMN stage of ESCC (all P<0.05). The positive expression of SRF had a correlation with positive expression of MYH9( r=0.521, P<0.05). The median survival time of SRF and MYH9 double negative expression group, SRF and MYH9 single positive expression group, SRF and MYH9 double positive expression group were 30, 20 and 12 months respectively.There were significant differences between the double negative, single positive expression groups and double positive expression groups (χ 2 values were 43.855, 17.799, all P<0.001), but there was no significant difference between the double negative and single positive expression groups (χ 2=2.787, P=0.095). Conclusion:SRF and MYH9 may be one of potential targets for diagnosis and treatment of esophagus cancer.

Fibroblast growth factor 21 (FGF21) has been only reported to prevent type 1 diabetic nephropathy (DN) in the streptozotocin-induced type 1 diabetes mellitus (T1DM) mouse model. However, the FVB (Cg)-Tg (Cryaa-Tag, Ins2-CALM1) 26OVE/PneJ (OVE26) transgenic mouse is a widely recommended mouse model to recapture the most important features of T1DM nephropathy that often occurs in diabetic patients. In addition, most previous studies focused on exploring the preventive effect of FGF21 on the development of DN. However, in clinic, development of therapeutic strategy has much more realistic value compared with preventive strategy since the onset time of DN is difficult to be accurately predicted. Therefore, in the present study OVE26 mice were used to investigate the potential therapeutic effects of FGF21 on DN.

Objective: To establish a preoperative evaluation model and evaluate the accuracy of postoperative complications by analyzing the risk factors of postoperative complications in hip arthroplasty in elderly patients, and to provide a basis for grading nursing. Methods: From January 2012 to August 2018, 148 patients with elderly patients undergoing hip arthroplasty admitted to People′s hospital of Wanning were included in the study. Among them, 23 patients with postoperative complications were included as complications and 125 patients without complications served as a control group. Univariate analysis of the factors associated with complications, statistically significant indicators were included in the multivariate logistic regression model, and the risk factors for postoperative complications in hip arthroplasty were analyzed. Based on the results of the regression analysis, a preoperative evaluation model was established. The ROC curve and the Hosmer-Lemeshow test were used to evaluate the model prediction performance. Results: Multivariate analysis showed age (OR=1.239, 95%CI: 1.002-1.531, P=0.048), Glu (OR=2.961, 95%CI: 1.055-8.311, P=0.039), surgical size (OR=4.997, 95%CI: 1.269-19.686, P=0.021) were risk factors for postoperative complications, Albumin (OR=0.696, 95%CI: 0.535-0.904, P=0.007) was a protective factor for postoperative complications (P<0.05). The ROC curve showed a nomogram model predicting the area under the complication curve (AUC) of 0.988 (95%CI:0.975-1.000), with a specificity of 96.77% and a sensitivity of 99.82%. Conclusion A nomogram model based on age, Glu, albumin, surgery size to predict the risk of complications after hip arthroplasty in elderly patients has a good specificity and sensitivity, high clinical value.

Objective To investigate the effects of 12-lipoxygenase (12-LO) and angiotensin Ⅱ (Ang Ⅱ) on the CIP/KIP family of cyclin-dependent kinase inhibitors (CKIs) p21,p27 and p57 related to cell hypertrophy.Methods Mesangial cells were treated with high glucose for 24 hours and 48 hours respectively.12(S)-hydroxyeicosatetraenoic acid [12(S)-HETE] and Ang Ⅱ were infused to rats by osmotic mini-pump for 1 week and 2 weeks respectively.Rats fed high fat diet were received low dose streptozotocin (STZ) to make type 2 diabetes (DN).The rats were divided into normal control group,DN group,DN+Ang Ⅱ type 1 receptor blocker (ARB) group or 12-LO inhibitor (CDC) group.DN+ARB rats were treated by losartan for 6 weeks,and DN+CDC rats were treated for 8 weeks.Urine albumin and protein expressions of p21,p27 and p57 were detected by ELISA and Western blotting respectively.Glomeruli injury and expressions of p21 and p27 were detected by PAS staining and immunohistochemistry respectively.Results High glucose increased p21 and p27 protein expression in mesangial cells significantly compared with the relative control (all P ＜ 0.05),but had no effect on p57.Ang Ⅱ increased p27 protein expression in gloneruli significantly (P ＜ 0.05),but had no effect on p21 and p57 protein expression.12(S)-HETE increased both p21 and p27 protein expression in glomeruli significantly (all P ＜ 0.05),but had no effect on p57 protein expression.Blood glucose,kidney/body weight,urinary protein,and glomerular p21 and p27 protein expressions were increased in DN group (all P ＜ 0.05) compared with those in control group,with little change of p57 protein expression (P ＜ 0.05).Moreover,glomerular hypertrophy and extra cellular matrix accumulation were observed in DN group.However,urine protein,kidney/body weight,renal injury,but not blood glucose,were decreased in DN+ARB group and DN+CDC group compared with DN group respectively (P＜ 0.05).Further DN+CDC rats had decreased both p21 and p27 protein expressions in glomeruli,but DN+ ARB rats only had decreased p27 protein expression (all P ＜ 0.05).Conclusions 12-LO may induce both p21 and p27 protein expression in DN glomeruli,but Ang Ⅱ may induce only p27 expression.
