Objective To construct a predictive model for the severity of depression based on the expression of circular RNAs(circRNAs)in peripheral blood.Methods Selecting 80 patients with depression who visited our hospital from August 2022 to August 2023,they were divided into a mild to moderate group of 49 cases and a severe group of 31 cases.Forty healthy individuals were selected as the healthy group,and after gene chip screening,five circRNAs with significant differences were selected.Further analysis was conducted on the relationship between circRNAs and the severity of depression,and independent risk factors affecting the severity of depression were analyzed,based on the analysis results,construct a depression severity prediction model using a column chart based on the expression of circRNAs in peripheral blood.Results Compared with the healthy group and mild to moderate group,the severe group had circRNA_100679,circRNA_1 03636 relative expression level decreased,circRNA_102802,circRNA_103964,The relative expression level of circRNA_002143 increased(P＜0.05).CircRNA_100679,circRNA_103636 is negatively correlated with the severity of depression(r=-0.594,-0.512,P＜0.05),circRNA_102802,circRNA_103964,circRNA_002143 is positively correlated with the severity of depression(r=0.603,0.425,0.412,P＜0.05).CircRNA_100679,circRNA_102802,circRNA_103636,circRNA_103964,circRNA_002143,family history of mental illness,and 5-hydroxytryptamine(5-HT)are all risk factors for the severity of depression(P＜0.05).The predicted area under the curve of the column chart prediction model based on risk factors such as peripheral blood circRNAs is 0.900,with a 95％CI:0.811-0.945.The model has good discrimination and high internal validation consistency.Conclusion The construction of a column chart model based on circRNAs expression for predicting the severity of depression has good predictive value and can provide reference for the diagnosis and treatment of depression severity in clinical practice.

OBJECTIVE: To detect the serum level of chemokine CXC motif chemokine 10 (CXCL-10) and Krebs von den lungen-6 (KL-6) in patients with rheumatoid arthritis associated interstitial lung disease (RA-ILD), and to analyze their correlation with RA-ILD, as well as the significance in RA-ILD. METHODS: A total of 169 RA patients were enrolled in the study. According to imaging findings of with and without ILD in high-resolution computed tomography scans of chest, the subjects were divided into RA-ILD group and RA-non-ILD group. According to the inclusion and exclusion criteria, 80 patients in each of the two groups were finally selected. Two groups were matched according to the 1 ∶ 1 ratio using propensity score matching (PSM). The serum CXCL-10 and KL-6 levels were detected by enzyme-linked immunosorbent assay. The clinical features, laboratory data and medications between the two groups were compared after PSM and the correlation between serum levels and clinical parameters were analyzed. Binary Logistic regression was used to analyze the risk factors of ILD in the RA patients, and the predictive value of CXCL-10 and KL-6 in RA-ILD was evaluated. RESULTS: In this study, 49 patients with RA-ILD and 49 patients with RA-non-ILD were selected by PSM. The levels of CXCL-10 and KL-6 in the RA-ILD group [64.36 (34.01, 110.18) ng/L, 360.70 (236.35, 715.05) U/mL] were significantly higher than those in the RA-non-ILD group [29.80 (16.89, 40.55) ng/L, 210.69 (159.98, 255.50) U/mL] (all P < 0.001). The results of correlation analysis showed that the level of serum CXCL-10 was positively correlated with the Warrick score on chest CT (r=0.378, P=0.007) and negatively correlated with the percentage of forced vital capacity to the predicted value (FVC%, r=-0.338, P=0.018). And the level of KL-6 was positively correlated with rheumatoid factor (RF, r=0.296, P=0.039) and negatively correlated with FVC% (r=-0.436, P=0.002) and the percentage of diffusion capacity for carbon monoxide to the predicted value (DLCO%, r=-0.426, P=0.002). Both univariate and multivariate Logistic regression analysis showed that CXCL-10 and KL-6 were positively correlated with ILD, the values of OR were 1.035 and 1.023 in CXCL-10 and those were 1.004 and 1.005 in KL-6 respectively (P < 0.05). The ROC curves were plotted with CXCL-10 and KL-6. The area under the curve (AUC) was 0.770 and 0.752 respectively. The AUC of combined detection increased to 0.800. CONCLUSION Serum levels of CXCL-10 and KL-6 are significantly elevated in patients with RA-ILD and correlated with the severity of ILD. The combined estimate of them helps to improve the effectiveness of diagnosis.

Objective To investigate the efficacy of microsurgery treatment with small craniotomy lateral fissure approach for hyperten-sive basal ganglia intracranial hemorrhage. Methods From December 2013 to February 2015, 30 patients with hypertensive basal ganglia intracranial hemorrhage ( blood loss within 30~60 mL) were analyzed respectively. Summarized the methods and techniques of this microsur-gery treatment and analyzed its advantages and disadvantages compared with the traditional operation. Results The hematomas were excluded more than 90% which were proved by reexamination after opreation. There was one case of temporal lobe infarction,but there was no re-bleed case and death case. The recovery of consciousness is good, and the limb function and language function were improved by early rehabilitation treatment. Conclusion Microsurgery treatment with small craniotomy lateral fissure approach for hypertensive basal ganglia intracerebral hemorrhage has the advantages of minimal invasion,complete hematoma removal and low complication and disability rates, which is worthy of promotion and application.
