Objective:To summarize and analyze the clinical characteristics and treatment outcomes of patients with recurrent pericarditis.Methods:This observational study consecutively recruited patients with recurrent pericarditis who were hospitalized at Peking University People′s Hospital between January 2017 and February 2024. Clinical characteristics and treatment outcomes were collected and summarized during follow-up.Results:A total of 8 recurrent pericarditis patients including 3 males were included, with an age of 34.0 (22.0, 39.5) years. In terms of clinical features, all patients presented with acute-onset severe chest pain, accompanied by fever in 7 and an audible pericardial friction rub in 2 patients. Electrocardiogram showed no diffuse ST-segment elevation or PR-segment depression in any patient. Echocardiography revealed pericardial effusion in all cases, with extensive fibrinous exudate and transient pericardial thickening observed in 6 patients. CT identified concurrent pleural and/or peritoneal effusions in 6 patients. All patients exhibited marked elevations in C-reactive protein, erythrocyte sedimentation rate and D-dimer levels. Whole-exome sequencing identified MEFV gene mutations associated with familial Mediterranean fever in 3 cases. Two patients developed cardiac tamponade requiring pericardiocentesis, which revealed hemorrhagic effusion. In the aspect of treatment outcomes, the time from recurrence to first confirmed diagnosis of recurrent pericarditis of this cohort was 14.5 (13.3, 19.5) d. Upon diagnosis, all patients promptly received standard anti-inflammatory therapy with ibuprofen and colchicine, achieving rapid relief. However, during a follow-up of 12.0 (6.0, 25.3) months, 3 patients experienced recurrence, and 2 developed transient constrictive pericarditis.Conclusion:Patients with recurrent pericarditis typically exhibit characteristic clinical presentations, laboratory abnormalities, imaging findings and potential genetic associations. Although standard anti-inflammatory therapy demonstrates favorable short-term efficacy, long-term management remains challenging due to the risks of recurrence and progression to constrictive pericarditis.

Objective:To analyze the cytological, histological, immunohistochemical, and molecular pathological features of hyalinizing trabecular tumor (HTT).Methods:Clinical and pathological data of the HTT cases diagnosed at Shanghai Sixth People′s Hospital affiliated to Shanghai Jiao Tong University School of Medicine between 2020 and 2024 were collected and analyzed. HE staining, special staining, immunohistochemical staining, and next-generation sequencing were performed on all cases.Results:Among the 10 HTT patients, 4 were male and 6 were female. The age at onset ranged from 29 to 85 years, with a median age of 49 (35,61) years. The maximum tumor diameter ranged from 0.3 to 5.3 cm. Cytologically, the smears were hypercellular and showed tumor cells arranged in nested clusters with visible basement membrane-like material. The nuclei were oval with finely granular chromatin, and nuclear pseudoinclusions were readily identifiable. Histologically, the tumors were well demarcated. The tumor cells were arranged in a paraganglioma-like pattern, exhibiting typical nuclear features of papillary thyroid carcinoma and psammoma bodies. Yellow bodies were observed in the cytoplasm. The stroma was rich in hyalinized material, which was periodic acid-Schiff stain (PAS)-positive. Immunohistochemically, the tumor cells showed diffuse expression of TTF-1 and focal expression of thyroglobulin. Aberrant immunoreaction with Ki-67 was present in the cytoplasm and membrane of the tumor cells. Molecular testing was performed on 8 cases. The PAX8-GLIS3 gene fusion was detected in 7 cases. Among these fusion-positive cases, 4 exhibited additional genetic abnormalities: one concurrent TSHR point mutation (p.D617H); one concurrent HRAS point mutation (p.Q61R); one concurrent LRP1B point mutation (p.S1752L), SUGCT point mutation (p.K137), and TERT point mutation (p.P785L); one concurrent MTOR mutation (7528+27A>T) and FLT3 mutation (p.E77K). The key initiating factors for thyroid carcinoma, including the BRAF V600E mutation and RET rearrangements, were absent in all cases tested.Conclusions:Cellular pleomorphism, yellow bodies and basement membrane-like material constitute important cytological and histological features for the differential diagnosis of HTT. Immunophenotypically, thyroglobulin may show focal expression, while Ki-67 is typically localized in the tumor cell membrane and cytoplasm. This study also demonstrates that PAX8-GLIS3 fusion is a characteristic molecular abnormality in HTT, although cases with wild type of GLIS gene may also present. Although rare, HTT may harbor point mutations in HRAS and TSHR, and other uncommon genetic alterations.

OBJECTIVE: To observe the clinical efficacy of acupoint thread-embedding for overweight and obese young adults with phlegm-dampness constitution. METHODS: A total of 66 young adults with overweight and obesity of phlegm-dampness constitution were randomly divided into an observation group (33 cases, 2 cases dropped out, 1 case was discontinued) and a control group (33 cases, 3 cases dropped out). Health education guidance was adopted in the control group. On the basis of the intervention in the control group, acupoint thread-embedding was applied in the observation group, two groups of acupoints were used alternately, i.e. bilateral Tianshu (ST25), Daheng (SP15), Daimai (GB26), Shuidao (ST28), Huaroumen (ST24), Fenglong (ST40) and bilateral Feishu (BL13), Geshu (BL17), Weiwanxiashu (EX-B3), Pishu (BL20), Shenshu (BL23), Dachangshu (BL25), once a week. Treatment of 8 weeks was required in the two groups. Before treatment, after 4 weeks and 8 weeks of treatment, the body weight, body fat rate, waist circumference and hip circumference were measured, and the body mass index (BMI) was calculated in the two groups; before and after treatment, the phlegm-dampness constitution score and the heart rate variability (HRV) related indexes (total power [TP], low frequency [LF], high frequency [HF], LF/HF, standard deviation of the normal to normal inter beat intervals [SDNN], root mean square of the successive differences [RMSSD], percentage of normal RR intervals with duration [PNN50]) were observed, and the clinical efficacy and constitution improvement rate were compared in the two groups. Six months after the treatment completion, the body weight of patients with effective clinical efficacy was observed, and the body weight rebound rate was compared in the two groups. RESULTS: After 4 weeks of treatment, the body weight, BMI, body fat rate, waist circumference and hip circumference were decreased compared with those before treatment in the two groups (P<0.05); after 8 weeks of treatment, the body weight, BMI, body fat rate, waist circumference and hip circumference were decreased compared with those before treatment and after 4 weeks of treatment in the observation group (P<0.05), and the body weight was decreased compared with that before treatment in the control group (P<0.05). After 8 weeks of treatment, the body weight, BMI, waist circumference, hip circumference and phlegm-dampness constitution score in the observation group were lower than those in the control group (P<0.05). The differences in the body weight, BMI, body fat rate, waist circumference and hip circumference between before treatment and after 4 weeks of treatment, as well as after 4 weeks of treatment and after 8 weeks of treatment in the observation group were higher than those in the control group (P<0.05). After treatment, the TP, LF, HF, SDNN and RMSSD in the observation group were higher than those in the control group (P<0.05). After treatment, the total effective rate was 90.0% (27/30) in the observation group, which was higher than 46.7% (14/30) in the control group (P<0.05); the improvement rate of phlegm-dampness constitution was 90.0% (27/30) in the observation group, which was higher than 50.0% (15/30) in the control group (P<0.05). Six months after treatment completion, the weight rebound rate was 37.0% (10/27) in the observation group, which was lower than 71.4% (10/14) in the control group (P<0.05). CONCLUSION Acupoint thread-embedding can effectively reduce the body weight, BMI, waist circumference, hip circumference and improve the phlegm-dampness constitution in overweight and obese young adults with phlegm-dampness constitution, regulate autonomic nerve disorders and improve vagus nerve activity, and has a certain long-term effect.

Objective:To investigate the magnetic resonance imaging (MRI) features of pediatric and adolescent mediastinal T-lymphoblastic lymphoma (T-LBL) and to evaluate their predictive value for early treatment response.Methods:A retrospective, multicenter case series study was conducted on 49 pediatric and adolescent patients diagnosed with mediastinal T-LBL between September 2020 and May 2024 at the Fifth Affiliated Hospital of Zhengzhou University, Beijing Gaobo Boren Hospital, and Henan Cancer Hospital.All patients underwent chest MRI, including conventional MRI sequences and diffusion-weighted imaging.Tumor imaging characteristics were analyzed, and quantitative parameters such as minimum apparent diffusion coefficient (ADCmin), maximum ADC (ADCmax), and mean ADC (ADCmean) were measured.Treatment response was evaluated 15 days post-treatment.The patients were divided into a response group (complete or partial response, 26 cases) and a non-response group (progressive disease or minor response, 23 cases).The relationship between MRI features and treatment response was analyzed.The intraclass correlation coefficient was used to assess inter-reader agreement, and independent sample t-tests and chi-square tests were employed to compare differences between groups.Receiver operating characteristic (ROC) curve analysis was conducted to evaluate the predictive performance of imaging parameters. Results:Significant differences were observed between the response and non-response groups in ADC values [ADCmin (0.80±0.41)×10 -3 mm 2/s vs.(1.23±0.70)×10 -3 mm 2/s, ADCmax (1.14±0.48)×10 -3 mm 2/s vs.(1.92±0.77)×10 -3 mm 2/s, ADCmean (0.98±0.42)×10 -3 mm 2/s vs.(1.56±0.74)×10 -3 mm 2/s] and the maximum tumor diameter was [(11.92±3.61) cm vs.(8.17±2.46) cm] (all P<0.05).ROC curve analysis showed that ADCmax had the highest predictive efficiency for treatment response, with an area under the curve (AUC) of 0.853 (95% CI: 0.790-0.910), sensitivity of 92.3%, and specificity of 65.2%.The AUC for the maximum tumor diameter was 0.814, demonstrating its excellent predictive performance. Conclusions:MRI features, particularly ADC values and the maximum tumor diameter, can effectively predict treatment response in pediatric and adolescent mediastinal T-LBL.

Objective:To explore the correlation between serum nidogen-2 (NID-2) and thoracic aortic calcification in patients with chronic kidney disease (CKD), and construct a risk prediction model based on NID-2 to evaluate its value in predicting the risk of the severe thoracic aortic calcification and cardiovascular and cerebrovascular events in CKD patients.Methods:It was a prospective cohort study. Patients with CKD at stage 3 to 5D in the Zhongda Hospital Affiliated to Southeast University from January 2022 to January 2023 were enrolled. Syngo.via software was used to evaluate the volume of thoracic aortic calcification, and enzyme-linked immunosorbent assay was employed to determine the level of serum NID-2. According to the volume of thoracic aortic calcification, the patients were divided into three groups: no calcification group, mild calcification group and severe calcification group. The top 25% of the patients were defined as no or mild calcification group, and the latter 75% were defined as severe calcification group. The follow-up period was one year. During the follow-up period, cardiovascular and cerebrovascular events, as well as all-cause death among the enrolled patients were recorded. Logistic regression analysis was used to screen the influencing factors of thoracic aortic calcification. Based on the results of logistic regression analysis, a nomogram prediction model was constructed. The receiver operating characteristic curve (ROC curve), calibration curve, and decision curve were employed to evaluate the discrimination, calibration and clinical practicality of the nomogram model.Results:A total of 132 patients were included, with 91 males (68.94%) and age of (56.51±16.37) years. There were 60 CKD 3-5 stage patients (non-dialysis, 45.45%) and 72 CKD 5D patients (dialysis, 54.55%). Serum ND-2 levels differed significantly among healthy individuals, dialysis patients and non-dialysis patients ( H=70.651, P<0.001). There was no statistically significant difference in serum NID-2 level between the no or mild calcification group and the severe calcification group in dialysis patients ( Z=350.00, P=0.426). The serum NID-2 level in the severe calcification group was significantly higher than that in the no or mild calcification group in non-dialysis patients ( Z=242.00, P=0.019). In non-dialysis patients, there was a statistically significant correlation between serum NID-2 level and volume of thoracic aortic calcification ( r=0.40, P<0.001). In dialysis patients, there was no statistically significant correlation between serum NID-2 level and volume of each segment of thoracic aortic calcification (all P>0.05). The univariate logistic regression analysis showed that, age, hemoglobin, serum albumin, estimated glomerular filtration rate, NID-2, hypertension, type 2 diabetes mellitus and cerebral infarction were correlated factors of thoracic aortic calcification in non-dialysis patients (all P<0.05). Multivariate logistic regression analysis showed that age ( OR=1.22, 95% CI 1.08-1.50, P=0.010) was an independent correlated factor of thoracic aortic calcification in non-dialysis patients. The above related variables of univariate logistic regression analysis were incorporated into a nomogram to construct a predictive model for severe vascular calcification in non-dialysis patients, yielding an AUC of 0.94 (95% CI 0.89-0.99) in ROC curve, with a sensitivity of 83% and a specificity of 95%. A nomogram model based on above variables for predicting cardiovascular and cerebrovascular events in non-dialysis patients demonstrated an AUC of 0.95 (95% CI 0.90-1.00) in ROC curve, with a sensitivity of 95% and a specificity of 87%. Conclusions:In non-dialysis patients, serum NID-2 level in the severe calcification group is significantly higher than that in the no or mild calcification group. The serum NID-2 is a related factor of thoracic aortic calcification and cardiovascular and cerebrovascular events in non-dialysis patients. The nomogram prediction model constructed by combining NID-2 with age, hemoglobin, serum albumin, estimated glomerular filtration rate, hypertension, type 2 diabetes mellitus and cerebral infarction has a high predictive value for the risk of thoracic aortic calcification as well as cardiovascular and cerebrovascular events in non-dialysis patients.
