Objective:To study the change of tumor necrosis factor-?(TNF-?) , interlukin-1?(IL-1?) and interluldn-6(IL-6) in neonates with hypoxic-ischemic encephalopathy(HIE) ,and analyze the relation between their levels and the severity of HIE. Methods :TNF-?,IE-? and IL6 in the plasma and in the supernatant of cultured peripheral blood mononuclearcytes(PBMC) were mesured in 50 neonates with HIE and 30 normal term neonates by enzyme-linked immunosorbent assay. Results: TNF-?and IL-?plasma levels and the production by PBMC in neonates with FILE were markedly elevated than those in normal controls Levels of TNF-?,IL-?and IL-6 both in the plasma and the supernatant of PB-MC were much higher in acute stage of severe HIE compared with the control group and mild HIE, and plasma levels of TNF-a and IL-? were significantly decreased in convalescence stage, but IL-6 levels were still much higher than those in normal controls. Conclusion:TNF-? and IL-? plasma levels and the production by PBMC in neonates with I-LIE axe related to the severity of HIE, and IL-6 may participate in the repair of neurons after ischemic brain injuly. These cytokines can be indicators of the brain damage degree of IDE.

Objective To explore the effect and molecular mechanism of proteasome inhibitor in TNF-related apoptosis-inducing ligand (TRAIL)-induced apoptosis resistance on malignant lymphoma cells.Methods Raji cells were treated with TRAIL and proteasome inhibitor (PS-341) in vitro and the cell growth index was evaluated by MTT assay; cell cycle was analysed by flow cytometry; the protein and mRNA level of Bax were measured by Western blotting and real time RT-PCR. Results TRAIL inhibited proliferation of Raji cells at the concentration of 500 μg/L, but the inhibition rate was lower than that of the control cell:Hmy2.ciR.TRAIL arrested cell in G0/G1 phase. The Bax protein in Raji is degraded, but the Bax mRNA expression level does not change significantly .The effects of TRAIL was enhanced significantly 10 nmol/L PS-341 was added. Conclusion Raji cells are resistant in TRAIL-induced apoptosis. This effect may be related to the decrease of Bax protein. The Ubiquitin-proteasome pathway is involved in the degradation of Bax in TRAIL-treated Raji cells.

Objective To analyze pathological and ultrasound imaging features of breast cancer in young women. Methods The pathological and ultrasound imaging data of 42 young female breast cancer patients(≤35 years old,the young group)between January 2016 and October 2017 from the Fourth Affiliated Hospital of China Medical University were retrospectively analyzed. Meanwhile, 62 elder female breast cancer patients (> 60 years old, the elder group) simultaneously diagnosed by pathology (age≥60 years) were randomly selected as the control group. Results The vessel carcinoma embolus rate and lymph node metastasis positive rate in the young group were higher than those in the elder group [31.0 % (13/42) vs. 29.0 %(18/62),59.5 %(25/42)vs.38.7 %(24/62)],and there was no difference between the two groups(χ2=16.187, χ2= 5.749, both P< 0.05). Compared with the elder group, the expression of estrogen receptor (ER) in the young group was lower (χ2= 11.598, P = 0.001). The positive rates of Ki-67 and human epidermal growth factor receptor-2 (HER-2) in the young group were higher (χ2= 5.396, P = 0.024; χ2= 5.166, P =0.026). Inhomogeneous internal echo of breast cancer, microcalcifications, flow classification (grade Ⅱ-Ⅲ) and resistance index (RI) ratio in the young group were higher than those in the elder group [83.3 % (35/42) vs. 59.7 % (37/62), P = 6.576; 57.1 % (24/42) vs. 22.6 % (14/62), P = 12.899; 78.6 % (33/42) vs. 58.1 % (36/62), P = 4.716; 83.3 % (35/42) vs. 59.7 % (37/62), P= 6.578], and the differences were statistically significant (all P < 0.05). Conclusion The young female breast cancer patients have a higher rate of malignancy,invasion and metastasis rate compared with the elder breast cancer patients.

This study is hopeful to provide specific measures for health education for clinical prostate cancer patients.

Objective:To investigate the value of radiomics signatures based on 18F-FDG PET/CT for predicting molecular classification and Ki-67 expression of breast cancer. Methods:A total of 134 female patients ((55.4±13.3) years) who underwent 18F-FDG PET/CT examination and were diagnosed with breast cancer by pathology in the First Affiliated Hospital of Soochow University from April 2016 to May 2023 were retrospectively enrolled. LIFEx software was used to extract radiomics features and the least absolute shrinkage and selection operator (LASSO) algorithm and independent-sample t test were used to screen potentially meaningful features and calculate the radiomics score, which were considered as radiomics models. Clinical characteristics were selected by supervised logistic regression and clinical models were established. Radiomics features and clinical characteristics were incorporated to logistic regression analysis to establish combined models. ROC curves were drawn and the differences among AUCs were analyzed by Delong test. Results:Among 134 patients, 22 were with triple negative breast cancer (TNBC), 47 were human epidermal growth factor receptor 2 (HER2) over-expression type, 37 were Luminal A type and the rest 28 were Luminal B type. The expression of Ki-67 was high in 85 patients, and was low in the rest 49 patients. The AUCs (95% CI) of the combined models for predicting TNBC, HER2 overexpression type, Luminal A type and Ki-67 expression were 0.843(0.770-0.900), 0.808(0.723-0.876), 0.825(0.711-0.908) and 0.836(0.762-0.894), respectively, which were higher than those of clinical models ( z values: 1.97-3.06, all P<0.05). Conclusion:The predictive model combining radiomics signatures based on 18F-FDG PET/CT and clinical characteristics can well predict the molecular classification and Ki-67 expression level of breast cancer.

Objective:To introduce the application of highly selective arterial indocyanine green angiography (hereinafter referred to as highly selective arterial angiography) in the design of anterolateral thigh free flap.Methods:This study was a retrospective observational study. From November 2023 to April 2024, 29 patients with wounds in extremities which were repaired by anterolateral thigh free flaps designed under the assistance of highly selective arterial angiography and met the inclusion criteria were admitted to the Department of Hand Surgery and Department of Wound Repair Surgery of Suzhou Ruihua Orthopedic Hospital, including 26 males and 3 females, aged 16 to 71 years. The wound area after debridement ranged from 8.0 cm×4.5 cm to 27.0 cm×16.0 cm. During the surgery, highly selective arterial angiography was used to assist in flap design. The fluorescence development range of the source arteries or perforators of flaps was observed. The blood supply range of the source arteries or perforators of flaps was determined based on the fluorescence development of the skin, and the excision position of the flap was adjusted. The flap incision area ranged from 9.0 cm×6.0 cm to 29.0 cm×16.0 cm. During the surgery, the number of highly selective arterial angiography, the type of source artery of perforators for puncture, and changes in the excision position of flaps were observed and recorded. After surgery, the blood supply and survival of flaps, the healing of wounds and the survival of skin grafts in the flap donor sites, and the angiography-related complications were observed.Results:All the 32 flaps of 29 patients were successfully excised. The highly selective arterial angiography was performed 37 times, including 13 cases of puncture of the oblique branch of the lateral circumflex femoral artery, 6 cases of puncture of the descending branch, 8 cases of double puncture of the oblique and descending branches, and 2 cases of puncture of arteries from other branches. During the surgery, the excision position of 28 flaps did not change, the excision position of 3 flaps moved towards proximal extremity of the thigh, and the excision position of 1 flap moved towards distal extremity of the thigh. All the flaps survived successfully after the surgery, and there was no partial necrosis of the flaps at the proximal or distal ends. The wounds in the flap donor sites healed, and all skin grafts survived. No angiography-related complications occurred.Conclusions:Highly selective arterial angiography can be used to determine the blood supply range of the source artery and perforators of the anterolateral thigh free flaps during the surgery. It can evaluate the blood supply of flaps more intuitively and objectively. Its application in assisting flap design can avoid partial flap necrosis caused by unreasonable preoperative design to a certain extent, and it is safe and reliable.

Objective:To explore the effect of adaptive nursing based on one point and two sources on the psychological resilience and self-care of patients with arrhythmia.Methods:From December 2020 to May 2021, patients with arrhythmias in Beijing Anzhen Hospital affiliated to Capital Medical University were selected by convenience sampling as research objects. The patients admitted from December 2020 to February 2021 were set in the control group ( n=163) , and the patients admitted from March to May 2021 were set in the observation group ( n=175) . The control group received routine nursing, while the observation group received adaptive nursing based on one point and two sources on the basis of the control group. The scores of the Chinese version of Connor-Davidson Resilience Scale (CD-RISC) and Exercise of Self-care Agency (ESEA) were compared between the two groups before and after intervention. Results:Before the intervention, there were no significant differences in the scores of CD-RISC and ESEA between the two groups ( P>0.05) . After intervention, the scores of CD-RISC and ESEA in the observation group were statistically higher than those in the control group ( P<0.01) . Conclusions:Adaptive nursing based on one point and two sources can effectively improve the psychological resilience of patients with arrhythmia, and improve their self-care, which is worth popularizing in clinical practice.
