Objective: To evaluate the value of CEUS in evaluating of malignant risk of breast imaging report and data system (BI-RADS) 4 levels of breast lesions with different sizes. Methods: The CEUS characteristics of BI-RADS 4 levels of the benign and malignant breast lesions with diameter ≤2 cm (n=120) and diameter >2 cm (n=63) were analyzed retrospectively. Binary Logistic regression analysis was used to screen CEUS characteristic parameters that could predict malignant lesions. Results: There were differences of enhanced shape, enhanced intensity, homogeneity, perfusion pattern, nourishing vessels, enhanced area expansion, initial rates and fading rates between the benign and malignant lesions with diameter ≤2 cm (all P<0.05); regression analysis showed that enhanced area expansion and nourishing vessels were independently correlated with malignant breast lesions of BI-RADS 4 levels (both P<0.05). There were differences of enhanced shape, perfusion pattern, nourishing vessels, enhanced area expansion and initial rates between the benign and malignant lesions with diameter >2 cm (all P<0.05); regression analysis showed that nourishing vessels, centripetal enhancement pattern and enhanced area expansion were independently correlated with malignant breast lesions of BI-RADS 4 levels (all P<0.05). Conclusion: CEUS can be used to evaluate the malignant risk of BI-RADS 4 levels of breast lesions with different sizes.

Objective To compare the differences between endoscopic resection and laparoscopy?assisted surgery or transanal endoscopic resection for rectal neuroendocrinal tumor. Methods Clinical data of patients who underwent endoscopic or surgical resection of neuroendocrinal tumor of less than 2 cm which were confirmed by pathology from December 2010 to November 2013 were retrospectively analyzed. Results Twenty cases of endoscopic treatment, including 17 cases of ESD, 3 cases of EMR,were included in endoscopy group;while 18 cases treated with surgery were included in surgery group, among which 12 ca?ses underwent transanal endoscopic microsurgery and 6 cases laparoscopic resection. The mean lesion sizes were 7 mm(4?18 mm)and 8 mm(3?15 mm),respectively. Pathology showed there were 16 cases of grade G1 neurocrinal tumor and 2 G2 cases in surgical group. There was no lymphvascular invasion with clear margin in the endoscopy group,but three cases of lymphvascular invasion in surgical group. No treatment?related se?vere adverse event occurred in either group. The time for oral food intake was 2?0 d(1?4 d) in endoscopy group, while that in surgery group was 2?4 d(1?7 d)(P=0?295). The hospital stay was(6?80±2?12) d in endoscopy group and(8?59±2?85)d in surgery group, respectively(P=0?034). And the total hospitalization cost was 10 488(4 128?15 296) yuan and 15 590(3 024?40 503) yuan(P=0?031) in the two groups, re?spectively. The follow?up was 25 months(2?48 months)and no recurrence was found. Conclusion Endo?scopic resection, especially ESD, is a new approach to treat colorectal neuroendocrinal tumor,advantageous over surgery in shorter hospitalization time, minimal invasiveness, faster postoperative recovery, less compli? cation, and reduced hospitalization cost.

Objective To explore the diagnostic value of endoscopic ultrasonography(EUS)for the minimal submucosal invasion of early gastrointestinal tumor. Methods A total of 242 patients with early gastrointestinal tumor,who underwent endoscopic submucosal dissection,were retrospectively analyzed. The accuracy of EUS diagnosis was calculated based on postoperative histopathological findings as the golden standard,and influencing factors were also analyzed. Results Overall diagnostic accuracy of EUS for sub-mucosal invasion of early gastrointestinal tumors was 72. 3%(175/ 242),with an overstaging rate of 21. 5%(52/ 242)and an understaging rate of 6. 2%(15/ 242).Tumor size(P = 0. 018)and location(P = 0. 005) had significant effects on the diagnostic accuracy of the minimal submucosal invasion of early gastrointestinal tumor by EUS. The overstaging rate in the lesion length of diameter>3 cm was higher than those of 3 cm or less[27. 0%(33/ 122)VS 15. 8%(19/ 120),P = 0. 807],the overstaging rates of early colonrectal and gastric cancer were also significantly higher than the understaging rate[ Colonrectum:12. 2%(9/ 74)VS 2. 7%(2/ 74),P= 0. 028;Stomach:26. 9%(28/ 104)VS 2. 9%(3/ 104),P = 0. 000]. Conclusion Endoscopic ultrasonography is of diagnostic value for the invasion depth of early cancer in gastrointestinal tract. However,precaution should be taken in large lesions and the tendency of overstaging in gastrointestinal tract.

Objective To evaluate the endoscopic features of colorectal sessile serrated adenoma/polyp(SSA/P). Methods The data of 109 cases of SSA/P and 218 cases of polyps randomly selected in Xijing Hospital from January 2014 to December 2016 were collected. The endoscopic features of SSA/P and polyps were compared, and the risk factors of occurrence and cancerization of SSA/P were analyzed. Results The mean age of patients in the SSA/P group was older than that of polyps group(P=0.011).The distribution of lesions was no significant difference between the two groups(P=0.092). The gross type of SSA/P was mainly type Ⅰ and Ⅱ, while polyps were more in type Ⅰ(P=0.036). According to the pit pattern of Kudo,type Ⅱ was more in SSA/P,but types Ⅰ and Ⅱ were more in polyps(P=0.004). For capillary pattern comparison,type Ⅱ was more in SSA/P,but type Ⅰ was more in polyps(P≤0.000 1). For surface morphological features comparison,the SSA/P group was more likely to be observed the mucous cap(P=0.002)and blood vessel thickening(P=0. 004). On pathologic diagnosis, the SSA/P group was more susceptible to atypia and carcinogenesis(P = 0.001). Higher microvascular morphological classification,being mucous cap,and blood vessel thickening were risk factors of atypia and carcinogenesis of SSA/P. Conclusion There were significant differences between SSA/P and polyps on lesion location,pit pattern,capillary pattern,surface structure characteristics,and risk factors of atypia and carcinogenesis.

Objective To compare the safety and efficacy of endoscopic submucosal tunnel dissection (ESTD) and endoscopic submucosal dissection ( ESD) for treatment of esophageal superficial neoplasms. Methods A retrospective study was performed on data of patients with esophageal superficial neoplasms who were treated by conventional ESD or ESTD at Xijing Hospital of Digestive Diseases between January 2014 and December 2016. The procedure time, pathology, rate of en bloc resection and curative resection, and adverse events were compared between the two groups. Results A total of 113 consecutive patients were collected, including 49 undergoing ESTD and 64 undergoing ESD. ESTD had a shorter procedure time than ESD method [38. 0 min(21. 4-71. 0 min) VS 46. 5 min(32. 5-117. 5 min), P＝0. 008],and the dissection speed of ESTD was faster than that of ESD[0. 42 cm2/min(0. 22-0. 59 cm2/min) VS 0. 34 cm2/min(0. 20-0. 42 cm2/min), P＝0. 000]. There were no statistical differences in the en bloc resection rate ( 100. 0% VS 100. 0%, P＝1. 000) or the curative resection rate (98. 0% VS 93. 8%, P＝0. 386).There were no statistical differences on adverse event rates including post-procedure bleeding, perforation, fever, and thoracalgia.ESTD group showed a lower rate of muscular injury (20. 4% VS 39. 1%, P＝0. 041) and intra-procedure bleeding (18. 4% VS 37. 5%, P＝0. 036). A multivariate regression analysis for procedure time showed that ESTD method ( OR＝ 2. 801, 95%CI: 1. 116-7. 031, P＝0. 028) and lesion area ＜9 cm2(OR＝5. 049, 95%CI: 2. 088-12. 208, P＝0. 000) were associated with a shorter procedure time.Conclusion ESTD is safe and effective for treatment of esophageal superficial neoplasms. It can shorten operative time, improve dissection speed, and reduce intra-procedure muscular layer injury and bleeding.

Objective:To investigate the characteristics of obesity in adolescents with major depressive disorder (MDD) and its association with the depressed severity.Methods:A total of 278 adolescents with MDD were recruited according to the inclusion and exclusion criteria. Their demographic data were collected and 24-item Hamilton depression scale (HAMD-24) was used to evaluate their severity of depression. According to the body mass index (BMI) classification standard of adolescents in China, all subjects were classified into four groups(wasting group, normal BMI group, overweight group and obesity group). SPSS 26.0 statistical software was used for data analysis. The Kruskal-Wallis test and the Chi-square test were separately used for the comparison of the four groups.Spearman correlation was used to explore the relationship between BMI and HAMD-24 scores and severity.Results:Among 278 adolescents with MDD, the prevalence of body abnormality was 32.4% (90/278), among which wasting, overweight and obesity were 9.0% (25/278), 14.4% (40/278) and 9.0% (25/278) respectively. There were statistically differences in gender ( χ2=17.018, P<0.001), HAMD-24 scores ( H=9.427, P=0.024) and depressed severity( H=8.508, P=0.037) among the four groups. Multiple comparisons showed that there were only statistically differences between obesity group and normal BMI group, that was the prevalence of obesity in males was higher than that in females ( χ2=13.631, P<0.001), and the level in HAMD-24 scores ( Z=2.956, P=0.003) and depressed severity ( Z=2.832, P=0.005) was lower in obesity group than that in normal BMI group.Spearman correlation analysis showed that BMI was negatively correlated with HAMD-24 scores ( r=-0.162, P=0.007). Conclusion:There is gender difference in obesity rates among the adolescent patients with first-episode untreated MDD. And the obese patients are less depressed than those with normal BMI.

Objective:To explore the effects of life events, family environment and coping style on self-injury behavior in adolescents with first-episode depression.Methods:From July 2019 to December 2022, a total of 110 adolescent patients with first-episode depression were selected in the Psychiatry Department of the First Affiliated Hospital of Zhengzhou University. According to whether the patients had self-injury behavior, the patients were divided into group without self-injury( n=54)and group with self-injury( n=56).Patients in the two groups were evaluated by a general clinical data questionnaire, adolescent self-rating life events checklist (ASLEC), family environment scale-Chinese version(FES-CV), simplified coping style questionnaire (SCSQ), 24 items Hamilton depression scale (HAMD-24), Hamilton anxiety scale (HAMA) and 90 symptom checklist-90 (SCL-90). Statistical analysis including t-test, χ2 test and binary Logistic regression analysis were performed on the enrolled data by SPSS 25.0 statistical software. Results:Among 110 patients, there were 56 patients(50.9%) exhibited self-injury behavior.The scores of ASLEC(51.04±5.99, 48.02±6.86), intimacy(3.70±1.85, 4.59±1.60), emotional expression(3.84±1.80, 4.69±1.96), positive coping styles(15.84±5.85, 18.22±4.84), negative coping styles(12.50±3.23, 11.06±3.64), and HAMA(20.63±2.86, 19.48±2.55) showed statistically significant differences between the group with and without self-injury ( t=-2.46, 2.72, 2.36, 2.32, -2.20, -2.21, all P<0.05). Binary Logistic regression analysis showed that life events ( B=0.079, OR=1.083, 95% CI=1.008-1.163, P=0.030), negative coping style ( B=0.173, OR=1.188, 95% CI=1.033-1.367, P=0.016), HAMA ( B=0.225, OR=1.252, 95% CI=1.057-1.482, P=0.009) were risk factors for self-injury, while intimacy ( B=-0.264, OR=0.768, 95% CI=0.593-0.995, P=0.046) and positive coping styles ( B=-0.092, OR=0.912, 95% CI=0.834-0.997, P=0.044) were protective factors for self-injury. Conclusion:The self-injury behavior of adolescents with first-episode depression may be related to negative life events, early adverse family environment and coping style.

Objective:To investigate the clinical characteristics, skeletal muscle pathologies and gene variations of chronic progressive external ophthalmoplegia (CPEO).Methods:Sixteen patients with conformed CPEO, admitted to our hospital from January 1997 to December 2021, were chosen. Their clinical data such as onset age and course of diseases and muscle pathological examination results were collected and their gene variation characteristics were analyzed.Results:The initial symptom in all 16 patients was ptosis of varying degrees; 15 patients were with eye movement disorder, 6 with diplopia, 4 with proximal limb weakness, and 3 with dysphagia and dysarthria. Among the 16 patients, electromyography showed myogenic damage in 7 patients, myogenic combined with neurogenic damage in 1 patient, neurogenic damage in 1 patient, and normal in 7 patients. Skeletal muscle biopsies indicated that 14 patients were with ragged red fibers (RRF), 11 patients had cytochrome C oxidase (COX)-negative muscle fibers, 3 patients had a small amount of degenerated and necrotic myofibers with mononuclear phagocytic infiltration. Immunohistochemical staining indicated infiltration of CD8 and CD68 positive lymphocytes. Ten patients accepted genetic test, indicating 6 patients with single large fragment deletion of mitochondrial DNA (mtDNA), 1 patient with mtDNA point mutation, 1 patient with nucleosomal DNA (nDNA) point mutation, and 2 patients without pathogenicity variation clearly associated with clinical phenotype. Electron microscopy in 5 patients showed that abnormal mitochondrial aggregation was noted in 4 patients under the sarcolemma and among the myofibrils.Conclusion:In addition to ptosis and eye movement disorders, a small number of patients with CPEO may be accompanied by dysphagia and limb weakness; and single large fragment deletion of mtDNA is the main mutation form of CPEO.
