Objective:To investigate the correlation between gallbladder polyps and colon polyps of different locations.Methods:Healthy subjects who underwent colonoscopy in the Physical Examination Center of the Affiliated Hospital of Yangzhou University from January 2020 to October 2022 were included. They were divided into the proximal colon group and the distal colon group according to the location of colon polyps. Gallbladder polyps were compared with other known risk factors for colon cancer. Different parts and types of polyps were further explored.Results:A total of 2 811 patients had colon polyps, including 1 668 males and 1 143 females, with an average age of 47.3 years. One hundred and seventy-one (6.1%) had gallstones, and 459 (16.3%) had gallbladder polyps. The incidence of gallbladder polyps was higher in the proximal colon polyp group (21.7%, 93/429). Gallbladder polyps were independently associated with proximal colon polyps, including hyperplastic polyps ( OR=1.525, P=0.029) and adenomatous polyps ( OR=1.425, P=0.017). There was no significant correlation between gallbladder polyps and distal colon polyps. Conclusion:Gallbladder polyps are associated with proximal colon polyps, and colonoscopy screening is recommended for people with gallbladder polyps.

OBJECTIVETo investigate the impact of intestinal spasmolytic on colon polyps and adenoma detection rate during colonoscopy.

METHODSLiteratures related to the effect of intestinal spasmolytic on colon polyp or adenoma detection rate were retrieved from PubMed, Medline, EBSCO, High Wire Press, OVID, EMBASE, and the China National Knowledge Articles, etc. published before July 2014. Unified data were extracted by two researchers independently and organized using Jadad scale to evaluate the quality of the enrolled studies through Review manager 5.2 Meta-analysis software.

RESULTSSix articles were enrolled with total 47,509 cases, including 16,867 cases in the scopolamine group and 30,642 cases in the placebo group. Meta analysis showed spasmolytic could increase the detective rate of polyps (OR=1.24, 95% CI:1.19-1.30), adenoma (OR=1.25, 95% CI:1.19-1.30) and high-risk adenoma (OR=1.22, 95% CI:1.16-1.29).

CONCLUSIONUsing colonoscopy spasmolytic scopolamine can increase the detection rate of colonic polyp and adenoma.

Objective To explore the relationship between the typing of MSCT and prognosis in infant with interstitial pneumonia (IP).Methods MSCT features of 44 infants with IP were analyzed retrospectively and classified according to the pathological pro-gress.The relationship between the MSCT typing and clinical prognosis was statistically analyzed.Results The result of the MSCT typing was as follows:the exudation in 22 cases,the proliferation in 18 cases and the ruin in 4 cases.There was significant difference for the clinical prognosis among the different MSCT groups (P＜0.01 ).And there was a significant correlation between the MSCT typing and clinical prognosis (r＝0.784,P＜0.01).The prognosis of the exudation type was better than the proliferation type,and both of them were better than the ruin type.Conclusion Based on the MSCT features,MSCT typing reveals the inflammatory patho-logical process of the infant IP,which plays an important role in treatment options decision and prognosis prediction.

Objective To evaluate the value of MRI texture analysis based on gray level co-occurrence matrix to predict cervical lymph node metastasis in patients with tongue carcinoma. Methods A total of 70 patients with tongue carcinoma confirmed by pathology were analyzed retrospectively. The patients were divided into cervical lymph node (LN) metastasis group (unilateral LN+, n=18;bilateral LN+,n=22) and no cervical lymph node metastasis(LN-,n=30). T1W, T2W and contrast-enhanced T1W images of the largest section of tumor were selected. ROI of the lesion was manually drew and GLCM texture parameters (energy, contrast, correlation, inverse difference and entropy) were extracted. The tumor length, thickness and para-lingual distance between tumor and tongue midline were also measured.Differences of all parameters were compared between LN+ group and LN- group, unilateral and bilateral cervical lymph node metastasis group, the parameters with statistically significant difference in predicting the efficiency of cervical lymph node metastasis were analyzed. The diagnostic efficiency of lymph node metastasis was calculated. Results The correlation, inverse difference and entropy based on T2WI showed significant difference (Zcor elation=2.97, tinverse dif erence=5.14, tentropy=2.41; P<0.05), entropy showed the best diagnostic efficiency, the area under the ROC curve (AUC) was 0.90, the cut off value was 7.19, the sensitivity was 80.0％, specificity was 86.7％. Only entropy showed significant difference between unilateral LN+group and bilateral LN+group (P<0.05), the AUC was 0.82, the cut off value was 7.47, the sensitivity was 90.9％, specificity was 78.8％. The index of tumor length, thickness and para-lingual distance between tumor and tongue midline all showed significant difference between LN+group and LN-group (P<0.05), the thickness showed the best diagnostic efficiency, the AUC value was 0.81, the cut off value was 11.19, the sensitivity was 78.0％, specificity was 81.7％. The index of tumor length, thickness and para-lingual distance between tumor and tongue midline showed no significant difference between unilateral LN+ group and bilateral LN+ group (P>0.05). The diagnostic sensitivity of radiologists was 65.0％ (26/40), the specificity was 80.0％ (24/32) on cervical lymph node metastasis. Conclusion Texture analysis based on T2WI can predict cervical lymph node metastasis in patients with tongue carcinoma. Entropy has certain value in predicting bilateral cervical lymph node metastasis.

Purpose: Knowing the distinction between benign and borderline/malignant phyllodes tumors (PTs) can help in the surgical treatment course. Herein, we investigated the value of magnetic resonance imaging-based texture analysis (MRI-TA) in differentiating between benign and borderline/malignant PTs. Methods: Forty-three women with 44 histologically proven PTs underwent breast MRI before surgery and were classified into benign (n = 26) and borderline/malignant groups (n = 18 [15 borderline, 3 malignant]). Clinical and routine MRI parameters (CRMP) and MRI-TA were used to distinguish benign from borderline/malignant PT. In total, 298 texture parameters were extracted from fat-suppression (FS) T2-weighted, FS unenhanced T1-weighted, and FS first-enhanced T1-weighted sequences. To evaluate the diagnostic performance, receiver operating characteristic curve analysis was performed for the K-nearest neighbor classifier trained with significantly different parameters of CRMP, MRI sequence-based TA, and the combination strategy. Results: Compared with benign PTs, borderline/malignant ones presented a higher local recurrence (p = 0.045); larger size (p < 0.001); different time-intensity curve pattern (p = 0.010); and higher frequency of strong lobulation (p = 0.024), septation enhancement (p = 0.048), cystic component (p = 0.023), and irregular cystic wall (p = 0.045). TA of FS T2-weighted images (0.86) showed a significantly higher area under the curve (AUC) than that of FS unenhanced T1-weighted (0.65, p = 0.010) or first-enhanced phase (0.72, p = 0.049) images. The texture parameters of FS T2-weighted sequences tended to have a higher AUC than CRMP (0.79, p = 0.404). Additionally, the combination strategy exhibited a similar AUC (0.89, p = 0.622) in comparison with the texture parameters of FS T2-weighted sequences. Conclusion MRI-TA demonstrated good predictive performance for breast PT pathological grading and could provide surgical planning guidance. Clinical data and routine MRI features were also valuable for grading PTs.

Objectives:the purpose of this study was to systematically evaluate the clinical value of cytokines in autoimmune diseases (AID). It was a kind of complex disease, and its pathogenesis involved cytokines, autoantibodies, immune cells and other immune factors. Especially some AID, such as Adult still′s disease (AOSD) and Takayasu arteritis(TA), had no specific biomarkers at present. This study was a retrospective case-control study.Methods:the data of tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), interleukin-8(IL-8) and interleukin-10(IL-10) in 834 AID patients from January 2019 to August 2022 were collected, and the serum levels of those cytokines in 30 healthy controls (HC) were detected at the same time. And AOSD, TA, systemic lupus erythematosus (SLE) and Behcet′s syndrome (BS) were divided into active group and inactive group. In addition, we also made a subgroup analysis of two important organs involved in SLE (kidney and nervous system). GraphPad Prism 9 and R 4.2.2 software were used. Nonparametric tests (Kruskal-Wallis H test, Mann-Whitney U test) were used to compare the differences among groups, and Dunn′s method was used to correct the false positive caused by multiple tests. Results:To compare the level of IL-6 in each group, except Behcet syndrome (BS) group and antiphospholipid syndrome (APS) group, the serum IL-6 level of AID group was higher than that of HC group, with antineutrophil cytoplasmic antibodies associated vasculitis(AAV) [3.85(2.00,8.55) pg/ml], idiopathic inflammatory myopathies(IIM) [7.80(2.50,6.50)pg/ml], IgG4-related disease(IgG4RD) [3.65(2.08,12.83) pg/ml], rheumatoid arthritis (RA) [5.50(2.20,16.10) pg/ml], SLE[4.70(2.75,16.55) pg/ml], Sj?gren syndrome(SS) [3.20(2.00,8.90) pg/ml], systemic sclerosis(SSc) [2.70(2.00,8.90) pg/ml], TA[3.40 (2.00,6.50) pg/ml], other AID diseases[4.40(2.00,11.10) pg/ml], especially AOSD [15.20(2.10, 39.20) pg/ml]. After correction, the differences were statistically significant ( P c<0.05). At the same time, the levels of serum TNF-α [7.40(5.60,10.95) pg/ml]and IL-10 [5.00(5.00, 7.58) pg/ml] in AOSD group were significantly higher than those in HC group[7.15(5.93,8.00) pg/ml,5.00(5.00,5.00) pg/ml] after correction ( P c<0.05). At the same time, the levels of serum TNF-α and IL-10 in AOSD group were higher than those in HC group. The serum levels of IL-6 and IL-8 in patients with active AOSD, BS, SLE and TA were significantly higher than those in patients without active disease (all P<0.05). In addition, the level of serum IL-8 in lupus nephritis group was significantly higher than that in non-lupus nephritis group ( P<0.05). At the same time, the serum levels of IL-6, IL-8 and TNF-α in neuropsychiatric lupus erythematosus group were significantly higher than those in non-neuropsychiatric lupus erythematosus group ( P<0.05), but there was no significant difference in IL-10 between neuropsychiatric lupus group and non-neuropsychiatric lupus erythematosus group. Conclusions:there was a close relationship between AID and cytokines. At present, the change of serum IL-6 level was the most classic one in clinical routine.
