Objective To explore the role and value of thromboelastography(TEG)combined with white matter hyperintensity(WMH)in predicting the functional prognosis of patients with non-cardiogenic acute ischemic stroke(AIS)through machine learning.Methods This study included 130 patients with non-cardiogenic AIS from August 2022 to February 2024.General clinical data,TEG and WMH information of all patients were collected.Three months later,functional outcomes were followed up using the modified Rankin scale(mRS),with an mRS score of≥2 indicating a poor prognosis.The prediction models were divided into four feature sets according to different ranges of predictors:set A(general clinical data+TEG indicators+WMH score),set B(general clinical data+TEG indicators),set C(general clinical data+WMH score),and set D(general clinical data).For each feature set,three machine learning algorithms,traditional logistic regression(LR)model,random forests(RF),neural network(NNET),and K-nearest neighbors(KNN),were used to construct models for predicting the 3-month neurological function outcome of patients with non-cardiogenic AIS.Bootstrap resampling internal validation was used to compare the performance of prediction models.Results The training and testing of the model were performed on 130 patient samples,and the AUC value and its confidence interval of the model were corrected by the 0.632+method(optimism correction).For the LR,NNET,and KNN models,the corrected AUC values of feature set A were significantly better than those of feature set D(DeLong test,P<0.05).For all models,the corrected AUC value of feature set A was higher than that of other feature sets.For feature set A,the corrected AUC value(0.830)of the NNET model was higher than that of other models.Among the 19 features of feature set A,six features with important associations with functional prognosis were selected including National Institute of Health stroke scale(NIHSS)score,stroke history,small artery occlusion subtype,periventricular white matter hyperintensities(PWMH)score,and TEG indicators maximum amplitude(MA)and LY30.Conclusion Combining TEG indicators and WMH information on the basis of general clinical data can significantly improve the accuracy of predicting poor functional prognosis in patients with non-cardiogenic AIS.The prediction models established by machine learning-based NNET and KNN algorithms have high predictive value.

Objective:To explore the significance of 99Tc m-sulfur colloid lymphoscintigraphy in the diagnosis of lower limb lymphedema after gynecological tumor surgery. Methods:The clinical data of patients with lower limb lymphedema after gynecological tumor surgery in Union Hospital Affiliated to Tongji Medical College of Huazhong University of Science and Technology from May 2015 to October 2019 were retrospectively analyzed. 99Tc m-sulfur colloid lymphoscintigraphy was performed in all patients. The results of lymphatic vessel imaging, lymph node imaging and their combination in the diagnosis of lower limb lymphedema were analyzed. The diagnostic efficacy of lymphatic vessel imaging alone, lymph node imaging alone and their combination was evaluated by the receiver operating characteristic (ROC) curve and the area under the curve (AUC), and the Youden index, sensitivity and specificity were calculated. Results:Among the 100 lower limbs of 50 patients, 56 limbs had lymphedema and 44 limbs had no obvious edema. When diagnosis was based on abnormal lymphatic vessel imaging alone, among 56 lower limbs with lymphedema, lower limbs lymphatic vessel imaging was positive in 38 (67.9%) and negative in 18 (32.1%); among 44 lower limbs without obvious edema, lower limbs lymphatic vessel imaging was positive in 6 (13.6%) and negative in 38 (86.4%); the sensitivity was 67.9%, the specificity was 86.4%, and the Youden index was 0.543. When diagnosis was based on abnormal lymph node imaging alone, among 56 lower limbs with lymphedema, lower limbs lymph node imaging was positive in 42 (75.0%) and negative in 14 (25.0%); among 44 lower limbs without obvious edema, lower limbs lymph node imaging was positive in 13 (29.5%) and negative in 31 (70.5%); the sensitivity was 75.0%, the specificity was 70.5%, and the Youden index was 0.455. When diagnosis was based on the combination of lymphatic vessel imaging and lymph node imaging, among 56 lower limbs with lymphedema, lymphatic vessel imaging and lymph node imaging were positive in 48 (85.7%) and negative in 8 (14.3%); among 44 lower limbs without obvious edema, lymphatic vessel imaging and lymph node imaging were positive in 14 (31.8%) and negative in 30 (68.2%); the sensitivity was 85.7%, the specificity was 68.2%, and the Youden index was 0.539. The AUC for the combined diagnosis of lymphatic vessel imaging and lymph node imaging was 0.781, the AUC for the diagnosis of abnormal lymphatic vessel imaging was 0.771, and the AUC for the diagnosis of abnormal lymph node imaging was 0.739 (all P < 0.01). Conclusions:99Tc m-sulfur colloid lymphoscintigraphy is of great help in the diagnosis of lower limb lymphedema after operation of gynecological tumors. The combination of lymph node imaging and lymphatic vessel imaging is more effective in the diagnosis of lower limb lymphedema.

Objective To compare the safety and clinical efficacy of transcatheter closure for ruptured aortic sinus aneurysm (RASA) with those of surgical treatment.Methods A total of 31 successive patients with RASA,who were treated in a single center during the period from October 2003 to May 2017,were enrolled in this study.Among them,11 patients received transcatheter closure therapy,their mean age was (36.64±10.87) years old;20 patients received surgical closure,their mean age was (28.90± 10.06) years old.The technical success rate,complications,residual shunt,operation time,hospitalization days,amount of blood transfusion,medical expenses,etc.were compared between the two groups.Results No statistically significant differences in age,sex and preoperative cardiac functional grading established by the Heart Disease Association of New York (NYHA) existed between the two groups (P＞0.05).The technical success rates in transcatheter closure group and surgical closure group were 100％ (11/11) and 95％ (19/20)respectively (P＞0.05).The amounts of blood transfusion in transcatheter closure group and surgical closure group were 0 ml and (427.25±331.36) ml respectively (P＜0.01).The time spent for operation in transcatheter closure group and surgical closure group was (60.00±00.00) min and (205.50±129.35) min respectively (P＜0.05).Days staying in intensive care unit (ICU) in transcatheter closure group and surgical closure group were 0 day and (1.50±0.61) days respectively (P＜0.01).The residual shunt rates in transcatheter closure group and surgical closure group were 9.09％ (1/11) and 10.00％ (2/20) respectively.None perioperative death occurred in both groups.No statistically significant differences in hospitalization days and in medical expenses existed between the two groups (P＞0.05).Conclusion Both transcatheter closure and surgical closure are safe and effective for the treatment of ruptured RASA,although transcatheter closure therapy has more advantageous in aspect of minimally-invasive management,operative time and length of hospital stay.For patients with a RASA which position is suitable for percutaneous interventional management,transcatheter closure therapy should be employed as a preferred therapy.

Purpose To explore the expression and clinical significance of CD47 in triple negative breast carcinoma (TNBC),and to analyze the relationship between CD47 expression and clinicopathologic features.Methods Immunohistochemical of Bond Polymer Refine Detection staining was performed on tissue array.It contains 185 cases of TNBC and 35 cases of non triple negative breast carcinoma (NTNBC).Then we observed the expression of CD47 in TNBC,and analyzed the relationship between the expression of CD47 and various clinical pathological characteristics.Results The expression of CD47 in tumor cells of TNBC was higher than that in NTNBC,and the difference was statistically significant (P ＜ 0.05).The CD47 expression rate in TNBC tumors was 52.3％.It was closely related to clinical stage (P ＜ 0.05),lymph node metastasis and distant metastasis (P ＜ 0.05) and vascular invasion (P ＜ 0.05).Conclusion The expression of CD47 is correlated with the clinical stage,lymph node metastasis,distant metastasis and vascular invasion of TNBC.CD47 can be used as a prognostic indicator and a potential target for immune therapy.

Objective: To investigate the correlation between the expression of PD-1, PD-L1 and clinicopathologic parameters in triple negative breast carcinoma (TNBC). Methods: Samples from 151 patients with TNBC and 65 cases of other breast carcinomas (non-TNBC) were examined for PD-L1 and PD-1 expression by immunohistochemical staining on tissue microarray. Results: The expression of PD-L1 and PD-1 in the tumor cells and interstitial lymphocytes in TNBC was significantly (P<0.05)higher than that in non-TNBC.In TNBC, the expression rates of PD-L1 in the cancer nests and stroma were 16.6%(25/151) and 25.2%(38/151)respectively.The former was positively correlated with tumor histological grade and lymph node metastasis (P<0.05), and the latter only with tumor histological grade (P<0.05). The expression rate of PD-1 was 27.2% (41/151), and correlated with PD-L1 expression in stromal tumor-infiltrating lymphocytes (P<0.05). Conclusion The expression of PD-L1 in TNBC is significantly correlated with high-grade histology, lymph node metastasis and PD-L1 expression in stromal tumor-infiltrating lymphocytes.

Objective: To analyze long-term therapeutic effect and safety of warfarin anticoagulant therapy of different intensity on aged patients with nonvalvular atrial fibrillation (NVAF). Methods: According to age, a total of 197 NVAF patients followed up for five years were divided into advanced aged group [n=65，≥80(85±2.09)years], aged group [n=75, 65-79(76.5±2.27) years] and middle-aged group [n=57, ＜65(57.4±2.18)]. All enrolled patients received long-term warfarin anticoagulant therapy, advanced aged group and aged group received low intensity anticoagulation, international normalized ratio (INR) was 1.6~2.5, while middle-aged group received standard intensity anticoagulation and the INR was 2.0~3.0. Thrombus events and incidence rates of hemorrhage etc. over five years were compared among three groups, and the safe dose range of warfarin was explored. Results: During five-year follow-up, no acute cerebral infarction occurred in three groups. The bleeding and other adverse reaction among three groups were no significant difference（P＞0.05). Compared with middle-aged group, there were significant reductions in warfarin dose [(3.29±0.49) mg/d vs. (2.95±0.38) mg/d, (2.85±0.49) mg/d],INR [(2.54±0.43) vs. (2.20±0.29), (2.16±0.32)] and CHA2DS2-VASc [(3.02±0.89) score vs.( 2.64±0.77) score vs.( 2.33±0.48) score]in aged group and advanced aged group, P＜0.01 all; but there were no significant difference between aged group and advanced aged group (P>0.05). There were no significant difference in incidence rates of mild hemorrhage (21.1% vs. 14.7% vs. 24.6%) and severe hemorrhage (1.8% vs. 1.3% vs. 1.5%) among middle-aged group, aged group and advanced aged group, P>0.05 all. Conclusion: When INR is closely monitored, INR controlled within 1.6~2.5, warfarin anticoagulation is safe and effective in aged patients with nonvalvular atrial fibrillation.
