Objective:To describe the prevalence of anxiety symptom and personality disorder among medical aesthetic clients,and explore related factors of anxiety symptoms among them.Methods:Totally 788 clients who consulted in a cosmetic plastic surgery department were recruited in a tertiary hospital in Beijing from November 2021 to July 2023.Using the Personality Diagnostic Questionnaire-4(PDQ-4)and the Self-Rating Anxiety Scale(SAS)as assessment instruments,with a cutoff point of 42 and 50 points respectively,for screening out personality disorder and anxiety symptom.Statistical analysis was conducted by analysis of variance,chi-square tests,multivari-ate linear regression and logistic regression.Results:The rate of anxiety symptom among the medical aesthetic cli-ents was of 15.23％(120/788),and the prevalence of personality disorder was 3.50％(28/788).Age was nega-tively associated with SAS scores(β=-0.82,P=0.009),PDQ-4 score was positively associated with SAS score(β=0.15,P＜0.001),eye plastic surgery,facial contouring and minimally invasive plastic surgery were positively associated with SAS score(β=2.00-3.64,P＜0.05).Conclusion:The younger and the more prominent the per-sonality dysfunction the clients are,the severer anxiety symptom they have.The clients who consult for eye plastic surgery,facial contouring,and minimally invasive plastic surgery have severer anxiety symptom.

Objective:To construct a nomogram model for differentiating gastric schwannoma (GS) from gastric stromal tumor (GST) (diameters 2 to 5 cm) based on CT imaging features before surgery.Methods:The clinical and imaging data of 49 patients with GS and 240 patients with GST in the Affiliated Hospital of Jining Medical University from July 2009 to April 2023 and Guangdong Provincial People′s Hospital from June 2017 to September 2022 were analyzed retrospectively. The independent factors for differentiating GS from GST were obtained by multivariate Logistic regression analysis. The nomogram model was constructed by R4.3.1 software. The efficacy of the nomogram model for differentiating GS from GST was evaluated by the receiver operating characteristics (ROC) curve, and calibration curve and decision curve analysis were used to evaluate the predictive efficacy and clinical application value of the nomogram model.Results:There were no statistical differences in the clinical symptom rate, calcification rate, ulcer rate, tumor vessel rate, ratio of long diameter to short diameter and CT value difference during the arterial and nonenhanced phases (CTV A-N) between GS patients and GST patients ( P>0.05). The proportion of female, incidence of lesions located in central or lower part of stomach, extraluminal or mixed growth rate, tumor-associated lymph node rate, strong enhancement rate, CT value difference during the portal and nonenhanced phases (CTV P-N), CT value difference during the delayed and nonenhanced phases (CTV D-N), CT value difference during the portal and arterial phases (CTV P-A) and CT value difference during the delayed and portal phases (CTV D-P) in GS patients were significantly higher than those in GST patients: 75.51% (37/49) vs. 58.33% (140/240), 85.71% (42/49) vs. 54.17% (130/240), 75.51% (37/49) vs. 45.00% (108/240), 44.90% (22/49) vs. 5.42% (13/240), 51.02% (25/49) vs. 27.08% (65/240), 32.0 (26.0, 43.5) HU vs. 29.0 (22.0, 37.7) HU, (44.59 ± 13.46) HU vs. (32.94 ± 12.47) HU, 20.0 (11.5, 25.0) HU vs. 10.0 (5.0, 17.0) HU and 9.0 (6.0, 12.0) HU vs. 4.0 (-2.7, 7.0) HU, the age, irregular shape rate, cystic degeneration rate and heterogeneous enhancement rate were significantly lower than those in GST patients: (58.12 ± 12.59) years old vs. (62.05 ± 11.22) years old, 16.33% (8/49) vs. 38.33% (92/240), 18.37% (9/49) vs. 51.25% (123/240) and 34.69% (17/49) vs. 56.25% (135/240), and there were statistical differences ( P<0.05 or<0.01). Multivariate Logistic regression analysis result showed that location, cystic degeneration, tumor-associated lymph node, CTV P-A and CTV D-P were the independent factors for differentiating GS from GST ( OR= 3.599, 0.201, 19.031, 1.124 and 1.160; 95% CI 1.184 to 10.938, 0.070 to 0.578, 6.159 to 58.809, 1.066 to 1.185 and 1.094 to 1.231; P<0.05 or<0.01). The nomogram model for differentiating GS from GST was constructed based on location, cystic degeneration, tumor-associated lymph node, CTV P-A and CTV D-P. The area under curve of the nomogram model for differentiating GS from GST was 0.924 (95% CI 0.887 to 0.951). The calibration curve analysis result showed that there was a good agreement between the predicted GS curve and the actual GS curve (the mean absolute error was 0.033). The result of the Hosmer-Lemeshow goodness-of-fit test indicated that the calibration of the nomogram model was appropriate ( χ2 = 2.52, P = 0.961). The clinical decision curve analysis result showed that when the threshold for the nomogram model for differentiating the two tumors was>0.03, the nomogram yielded more net benefits than the "all patients treated as GS" or "all patients treated as GST" scenarios. Conclusions:The nomogram model based on CT imaging features can be used to differentiate GS from GST before surgery.

Objective:To explore the value of conventional magnetic resonance imaging (MRI), diffusion weighted imaging (DWI), diffusion kurtosis imaging (DKI) sequence and pathological examination in predicting the efficacy of neoadjuvant chemotherapy (NAC) in advanced breast cancer.Methods:The clinical data of 65 cases of advanced breast cancer with NAC confirmed by pathology in the Affiliated Hospital of Jining Medical University from March 2022 to May 2023 were retrospectively analyzed, including 20 cases in the pathological complete remission (pCR) group and 45 cases in the non pCR group; All patients underwent routine MRI, DWI, DKI examinations and pathological analysis. The clinical pathological data, routine MRI features, apparent diffusion coefficient (ADC) values, mean kurtosis coefficient (MK), and mean diffusion coefficient (MD) between the two groups were analyzed; We compared the differences in various parameters between two groups and plotted receiver operating characteristic (ROC) curves to compare their diagnostic efficacy of NAC in breast cancer.Results:There were significant differences in molecular typing, estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (Her-2) and Ki-67 between pCR group and non pCR group (all P<0.05). In pCR group, Her-2 overexpression type and triple negative breast cancer (TNBC) type breast cancer were more common. ER and PR were mostly negative, Her-2 was mostly positive, and Ki 67 was mainly positive. The difference in tumor T2WI signal between the pCR group and the non pCR group was statistically significant ( P<0.05), with the pCR group showing mostly moderate/low T2WI signal. The ADC and MD values of the pCR group were lower than those of the non pCR group, while the MK value of the pCR group was higher than that of the non pCR group, and the differences were statistically significant (all P<0.001). The area under the ROC curve (AUC) for predicting the efficacy of NAC using a clinical pathological model was 0.829, which was higher than the AUC of molecular subtypes, ER, PR, Her-2, and Ki-67 ( Z=3.008, 2.697, 2.815, 2.131, 2.376, all P<0.05); The AUC of the DKI+ DWI predicting the efficacy of NAC was 0.934, which was higher than that of the DWI single sequence model, and the difference in type was statistically significant ( Z=2.396, P=0.017). The diagnostic efficacy of the DKI+ DWI model was higher than that of the single parameter ADC, MD, and MK, and the differences were statistically significant ( Z=2.396, 2.219, 2.161, all P<0.05); The AUC of the combined imaging and pathology model was 0.983, and its diagnostic efficacy was higher than that of the conventional MRI feature model, pathology model, DWI model, and DKI model, with statistically significant differences ( Z=5.877, 2.961, 3.240, 2.264, all P<0.05). Conclusions:The results of pathology, conventional MRI, DWI and DKI parameters of pCR and non pCR breast cancer patients are significantly different, and the combined model is better than the single model in predicting the efficacy of NAC.

Objective:To investigate the prevalence of anxiety disorder and its distribution,and related factors in adults in Ningxia community.Methods:Using the method of China Mental Health Survey,anxiety disorder was investigated with the Composite International Diagnostic Interview,and related factors were analyzed.Twelve-month prevalence and life-time prevalence and their distributions were calculated according to DSM-Ⅳ criteria.Results:A total of 4 085 respondents were interviewed in the survey.The 12-month prevalence rate of any anxiety disorder was 4.2％,and the lifetime prevalence rate was 5.6％.The 12-month prevalence rates of social phobia,special phobia and generalized anxiety disorder were higher in women than in men(P＜0.05).The prevalence of special phobia and any anxiety disorder in rural area was higher than that in urban area.Logistic regression model revealed that fe-male(OR=1.86,95％CI:1.32-2.64)had higher prevalence risk of anxiety disorder,and individuals with somat-ic pain had higher risk of anxiety disorder than those without(P＜0.05).Conclusion:Anxiety disorder is prevalent in Ningxia.It suggests that strengthening somatic pain community mental health service is necessary to develop tar-geted intervention programs among the high-risk population.

Objective:To investigate the prevalence of alcohol use disorder in adult residents in Ningxia and related factors,and to provide scientific evidence for intervention.Methods:In this cross-sectional study,multi-stage sampling was administrated.According to the diagnostic criterion of the Diagnostic and Statistical Manual of Mental Disorder,Fourth Edition(DSM-Ⅳ),face-to-face interview in household was carried out using Composite Interna-tional Diagnostic Interview in Ningxia Hui Autonomous Region.The prevalence of alcohol use disorder and the re-lated factors were analyzed.Results:In 4 085 residents who completed the survey,the 12-month prevalence of alco-hol use disorder was 1.2％,and the life-time prevalence rate was 3.5％.The twelve-month prevalence rates of alco-hol abuse and alcohol dependence were 1.1％and 0.6％,respectively,and the life-time prevalence rates of them were 2.8％and 1.2％,respectively.Comparing with control population,male(OR=10.84,95％CI:2.88-40.87),age groups of 18 to 29 years old(OR=3.67,95％CI:1.27-10.59),30 to 39 years old(OR=5.12,95％CI:1.98-13.24),and 40 to 49 years old(OR=3.82,95％CI:1.45-10.06),secondary school(OR=3.07,95％CI:1.22-7.75),high school or above(OR=3.13,95％CI:1.21-8.12),smoking(OR=3.00,95％CI:1.34-6.70)and body pain(OR=1.88,95％CI:1.05-3.36)were risk factors of alcohol use disorder.Conclusions:The prevalence of alcohol use disorder in different populations distribute dissimilarly in Ningxia.Males,middle-aged and young people,smokers,and those with physical pain should be key objects of intervention for alcohol use disorders.

Objective:To evaluate the value of CT for differentiating gastric leiomyoma (GLM) from gastric schwannoma (GS).Methods:The clinical and imaging data of 42 patients with GLM (GLM group) and 41 patients with GS (GS group) were analyzed retrospectively. The general information and CT features were compared between two groups. The independent factors for differentiating GLM from GS were obtained by multivariate Logistic regression analysis. The receiver operating characteristic curve (ROC) was used to evaluate the diagnostic efficiency of the model.Results:The proportion of female and age in GLM group were significantly lower than those in GS group: 59.52% (25/42) vs. 85.37% (35/41), (51.83 ± 10.52) years old vs. (58.80 ± 10.63) years old, and there were statistical differences ( P<0.01). The upper part of the stomach rate, irregular shape rate, intraluminal growth rate, ratio of long diameter to short diameter and mild to moderate enhancement rate in GLM group were significantly higher than those in GS group: 71.43% (30/42) vs. 14.63% (6/41), 52.38% (22/42) vs. 21.95% (9/41), 92.86% (39/42) vs. 19.51% (8/41), 1.90 ± 0.55 vs. 1.34 ± 0.28 and 92.86% (39/42) vs. 51.22% (21/41), the cystic degeneration rate, ulcer rate, incidence of tumor-associated lymph node, CT values of venous phase and delayed phase in GLM group were significantly lower than those in GS group: 2.38% (1/42) vs. 26.83% (11/41), 7.14% (3/42) vs. 24.39% (10/41), 2.38% (1/42) vs. 60.98% (25/41), (59.21 ± 9.75) HU vs. (66.22 ± 10.33) HU and (65.02 ± 8.62) HU vs. (76.85 ± 11.89) HU, and there were statistical differences ( P<0.01 or <0.05); there were no statistical difference in the rate of calcification and the CT values of plain scan and arterial phase between the two groups ( P>0.05). Multivariate Logistic regression analysis result showed that the tumor location, growth mode, tumor-associated lymph node and ratio of long diameter to short diameter were the independent factors for differentiating GLM from GS ( OR = 34.385, 25.314, 0.023 and 97.700; 95% CI 2.848 to 415.171, 2.674 to 239.670, 0.001 to 0.637 and 3.113 to 3 066.549; P<0.01 or <0.05); when the model threshold was >0.647, the area under the curve was 0.988 (95% CI 0.934 to 1.000), with a sensitivity of 92.9% and specificity of 97.6%. Conclusions:When the tumor is prone to the upper part of the stomach, intraluminal growth, ratio of long diameter to short diameter >1.28, and the absence of the tumor-associated lymph node, GLM tends to be considered, on the contrary, it tends to be GS. Therefore, CT imaging features have certain value in differentiating GLM from GS before surgery.

Objective:To investigate the mechanism of crossed cerebellar diaschisis(CCD) induced by supratentorial tumors and the characteristics of 18F-FDG PET/CT imaging. Methods:Eighty-six patients with supratentorial tumors who underwent 18F-FDG PET/CT whole-body imaging from January 2017 to June 2021 were retrospectively analyzed.Placement, number, size, SUVmax, CT values, relationship with basal ganglia, edema, and cerebellar asymmetry index (AI) were observed and recorded.The imaging differences between patients with CCD and patients without CCD were compared, and the correlations between SUVmax, maximum diameter and cerebellar AI were analyzed.SPSS 21.0 software was used for statistical analysis.Chi-square test, independent sample t-test and Pearson correlation analysis were used for data statistics. Results:Among the 86 patients, 14 were patients with CCD and 72 were patients without CCD.The incidence of CCD was 16.3%.There were statistically significant differences in whether the primary lesions involved the basal ganglia region between patients with CCD and patients without CCD ( χ2=7.637, P=0.006). The cerebellar AI ((0.27±0.09), (0.05±0.02), t=6.847, P=0.003)and maximum diameter of primary lesions((3.98±1.09)cm, (2.36±1.61)cm, t=2.011, P=0.040) in patients with CCD were both larger than those in patients without CCD.There was a significant positive correlation between cerebellar AI and the maximum diameter of primary lesions in patients with CCD ( r=0.375 P=0.028). Conclusion:18F-FDG PET/CT imaging can assist in the diagnosis of crossed cerebellar diaschisis.The primary lesion of supratentorial tumor involving the basal ganglia is more likely to cause crossed cerebellar diaschisis, and the size of the primary lesion is correlated with cerebellar AI.
