BACKGROUND: The clinical features of enthesitis in patients with psoriatic arthritis (PsA) have been reported in some Western countries, but data in China are very limited. This study aimed to describe the characteristics of enthesitis in Chinese patients with PsA and compared them with those in other cohorts. METHODS: Patients with PsA enrolled in the Chinese Registry of Psoriatic Arthritis (CREPAR) (December 2018 to June 2021) were included. Data including demographics, clinical characteristics, disease activity measures, and treatment were collected at enrollment. Enthesitis was assessed by the Spondyloarthritis Research Consortium of Canada (SPARCC), Maastricht ankylosing spondylitis enthesitis score (MASES), and Leeds enthesitis index (LEI) indices. A multivariable logistic model was used to identify factors related to enthesitis. We also compared our results with those of other cohorts. RESULTS: In total, 1074 PsA patients were included, 308 (28.7%) of whom had enthesitis. The average number of enthesitis was 3.3 ± 2.8 (range: 1.0-18.0). More than half of the patients (165, 53.6%) had one or two tender entheseal sites. Patients with enthesitis had an earlier age of onset for both psoriasis and arthritis, reported a higher proportion of PsA duration over 5 years, and had a higher percentage of axial involvement and greater disease activity. Multivariable logistic regression showed that axial involvement (odds ratio [OR] 2.21, 95% confidence interval [CI], 1.59-3.08; P <0.001), psoriasis area and severity index (PASI) (OR: 1.03, 95% CI: 1.01-1.04; P = 0.002), and disease activity score 28-C reactive protein (DAS28-CRP) (OR: 1.25, 95% CI: 1.01-1.55; P = 0.037) were associated with enthesitis. Compared with the results of other studies, Chinese patients with enthesitis had a younger age, lower body mass index (BMI), a higher rate of positive human leukocyte antigen (HLA)-B27, more frequent dactylitis, and a higher proportion of conventional synthetic disease-modifying antirheumatic drugs' (csDMARDs) use. CONCLUSIONS Enthesitis is a common condition among Chinese patients with PsA. It is important to evaluate entheses in both peripheral and axial sites.

Cysteine protease inhibitor 1 (CST1) is a member of type 2 Cystatins superfamily, plays a key role in targeted regulation. CST1 is highly expressed in gastric cancer, promotes tumor cell migration and invasion by activating the epithelial-mesenchymal transformation pathway and Wnt pathway, and regulates tumor growth and progression in combination with the corresponding target genes of homeobox C10 and glutathione peroxidase 4. A deeper understanding of the role and function of CST1 in gastric cancer will help to further develop potential therapeutic targets and diagnostic and prognostic markers for gastric cancer.

Objective:To investigate the influence of lymphadenectomy on efficacy of patients with intrahepatic cholangiocarcinoma (ICC) at different locations.Methods:The retro-spective cohort study was conducted. The clinicopathological data of 123 patients with ICC who were admitted to the Affiliated Hospital of North Sichuan Medical College from January 2015 to January 2022 were collected. There were 78 males and 45 females, aged 55(rage, 50?60)years. All patients underwent radical resection. Observation indicators: (1) clinical characteristics of patients with ICC; (2) follow-up; (3) surgical situations in ICC patients with different number of lymph nodes dissected. Measurement data with normal distribution were represented as Mean± SD, and compari-son between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Kaplan-Meier method was used to draw survival curve and Log-Rank test was used for survival analysis. Results:(1) Clinical characteristics of patients with ICC. Of the 123 patients, 81 cases had peripheral ICC and 42 cases had central ICC. The albumin-bilirubin grade (grade 1, grade 2?3), preoperative lymph node metastasis risk assessment (low risk, high risk), the number of lymph nodes dissected (<6, ≥6), lymph node metastasis (positive, negative) were 57, 24, 51, 30, 49, 32, 15, 66 in patients with peripheral ICC, versus 19, 23, 17, 25, 14, 28, 16, 26 in patients with central ICC, showing significant differences in the above indicators between them ( χ2=7.40, 5.66, 8.17, 5.62, P<0.05). (2) Follow-up. All the 123 patients were followed up for 28(range, 21?38)months. The 3-year overall survival rate was 57.8% in the 81 patients with peripheral ICC, versus 32.3% in the 42 patients with central ICC, showing a significant difference between them ( χ2=5.98, P<0.05). Of the 42 patients with central ICC, there were 25 cases with high risk of lymph node metastasis before surgery and 17 cases with low risk of lymph node metastasis before surgery. Of the 25 central ICC patients with high risk of lymph node metastasis before surgery, the 3-year overall survival rate was 28.9% in the 18 cases with the number of lymph nodes dissected ≥6, versus 14.3% in the 7 cases with the number of lymph nodes dissected <6, showing a significant difference between them ( χ2=8.90, P<0.05). (3) Surgical situa-tions in patients with the different number of lymph nodes dissected. Of the 123 patients, cases with the number of lymph nodes dissected <6 and ≥6 were 63 and 60, and there was no significant difference in the operation time, intraoperative blood transfusion, postoperative complications, bile leakage, liver insufficiency, pulmonary infection, pleural effusion, abdominal effusion, or lymphatic leakage between them ( P>0.05). One patient might have multiple complications. Conclusions:The prognosis of patients with peripheral ICC is better than that of patients with central ICC. For patients with central ICC who are at high risk of lymph node metastasis before surgery, adequate lymph node dissection may result in a better prognosis.

Forkhead box protein A2 (FOXA2) , characterized by its unique DNA binding domain, plays a key role in transcriptional regulation. FOXA2 transcription factor is highly expressed in colorectal cancer, and binds with corresponding targeted genes to regulate tumor growth and inflammatory response, thus playing the role of oncogenes. In-depth understanding of the role and function of human FOXA2 transcription factor in colorectal cancer will contribute to further development of FOXA2 as a potential therapeutic target and diagnostic and prognostic marker of colorectal cancer.

Objective:To study the differences in the dosimetry and delivery time between helical tomotherapy (HT) and volumetric modulated arc therapy (VMAT) in postoperative radiotherapy of synchronous bilateral breast cancer (SBBC) and to explore the feasibility of clinical application of the HT technology.Methods:A retrospective analysis was conducted for nine SBBC patients who underwent modified radical postoperative radiotherapy in the Fourth Affiliated Hospital of Guangxi Medical University from February 2017 to May 2022. For each patient, the Precision planning system was used to formulate the HT plan, and the RayStation planning system was employed to develop the VMAT plan. All plans obtained were divided into HT group and VMAT group according to plan type. The paired sample t-test was used to compare the dosimetric parameters of the target volume and organ at risk (OAR) and delivery time between the two radiotherapy technologies. Results:The plans of both groups could meet the clinical treatment requirements. The coverage ( D95% and V100%), conformity index (CI), average dose ( Dmean), and median dose ( D50%) of the target volumes in the HT group were better than those in the VMAT group, and the differences were statistically significant ( t=-3.21, -3.39, -5.03, 3.76, 4.97, P < 0.05). The differences in the maximum dose ( D2%), minimum dose ( D98%), high dose volumes ( V107% and V110%), and homogeneity index (HI) of the target volumes between the two groups were not statistically significant ( P > 0.05). Regarding the OAR, the V20 and Dmean of both lungs in the HT group were significantly lower than those in the VMAT group, but the irradiation volume V5 of both lungs in the HT group was significantly higher than that in the VMAT group ( t=-3.01, 3.83, -2.81, P < 0.05). Moreover, V20, V30, V40, and Dmean of heart and the V20 and Dmean of liver in the HT group were significantly lower than those in the VMAT group, with statistically significant differences ( t=3.76, -2.83, -2.74, 5.93, 4.57, 4.48, P < 0.05). There was no significant difference in the radiation doses to other OARs (spinal cord, thyroid gland, and humerus head, P > 0.05). The delivery time of the HT group was significantly higher than that of the VMAT group ( t = 11.32, P < 0.05). Conclusions:Compared with VMAT, HT has greater dosimetric advantages, and can provide higher target coverage, conformability and average dose, and significantly reduce the overall radiation doses to both lungs, heart, and liver in OARs. However, the irradiation volume V5 at low-dose areas of both lungs and the delivery time in the HT group are higher than those in the VMAT group, but still meet the clinical treatment requirements. Therefore, it is feasible to apply the HT technology to the modified radical postoperative radiotherapy of SBBC.
