Objective To observe the effect of TOMATIS auditory training on improving cognitive and post-traumatic stress disorder in patients after breast cancer chemotherapy. Methods Eighty invasive ductal carcinoma of breast cancer patients with cognition and psychological disorders were selected in the breast department of Tangshan People's Hospital from October 2016 to September 2017. All patients were randomly divided into control group ( n=40) and experimental group ( n=40) . The experimental group was given the TOMATIS high and low audio frequency auditory training,and the control group was given ordinary music training. Before and after the intervention, the Chinese version of the Montreal cognitive assessment scale ( MoCA) and the post-traumatic stress disorder scale ( PTSD-SS) were evaluated for both groups of pa-tients. Results After the intervention,the experimental group had significantly higher scores in visual struc-ture skills((3. 83±0. 71)vs(2. 68±0. 57)),executive function ((2. 23±0. 53)vs(1. 55±0. 50)),attention and concentration((1. 55±0. 78)vs(1. 23±0. 53)),language((1. 50±0. 75)vs(1. 08±0. 47)),calculation ((2. 00±0. 60)vs(1. 45±0. 75)),abstract thinking((1. 63±0. 54)vs(1. 00±0. 51)),memory((4. 68± 0. 47)vs(2. 70±0. 72)),directive force((5. 25±0. 54)vs(3. 90±0. 81)) and total score((22. 65±2. 89)vs (15. 58±2. 10))than the control group(all P<0. 05). After intervention,the scores of subjective assessment of traumatic events((2. 60±0. 63)vs(3. 98±0. 62)),repeated recurring experiences((24.05±2.72)vs (26. 70±2. 28)),avoidance symptoms((24. 35±1. 64)vs(26. 40±1. 19)),increased alertness((24. 23± 1. 80)vs(25. 45±1. 20)),impaired social function((7. 28±1. 01)vs(8. 68±0. 66)),and total scores((85. 85±5. 13)vs(94. 63±2. 92)) in the experimental group were significantly lower than those in the control group,and the differences were statistically significant ( all P<0. 01) . Conclusion TOMATIS auditory train-ing can effectively improve the cognitive function and psychological state in breast cancer chemotherapy pa-tients,which is worthy of popularization and application.

Objective To investigate the value of tracing thyroglobulin(Tg)in predicting metastasis of post-operative patients with differentiated thyroid carcinoma(DTC)before its first pre-ablation with 131I. Methods 106 cases with DTC, undergoing total thyroidectomy and lymphadenectomy, were assigned to 2 groups as M0 group (without metastasis)and M1 group(with metastasis). Clinical data including pre-ablation stimulated thyroglobulin (sTg)and pre-operative Tg were determined. sTg, pre-operative Tg, Tg variation(△Tg), and Tg variation rate (△Tg/pre-operative Tg)between 2 groups were compared. The ROC curve and the diagnostic critical point(DCP) were analyzed. Results sTg, Pre-operative Tg, Tg variation, and Tg variation rate were significantly higher than those of M0(all P<0.01). The corresponding areas under the ROC curve(AUC)to differentiate the two groups were 0.913,0.702,0.773,and 0.943,respectively. The best diagnostic value points(DCP)were 40.60 ng/ml and-72.5%. The sensitivity and specificity were 70. 21%, 100. 00%, and 89. 36%, 88. 13%, respectively. Conclusion The pre-ablation sTg seems to be a useful diagnostic marker for predicting metastasis before the first 131I ablation. The sTg value can be effectively corrected by the Tg variation rate,and the sensitivity and accuracy of sTg for metastasis in DTC patients can be improved,finally providing evidence for pre-ablative assessment as well as strategies of 131I therapy.

Objective To observe the effect of Tomatis converted auditory training on the executive functioning of breast cancer patients undergoing chemotherapy.Methods Eighty breast cancer patients with the executive dysfunction who were undergoing chemotherapy were divided into a control group and an experimental group,each of 40.The experimental group was given Tomatis high and low frequency auditory training,while the control group was given ordinary music training.The patients in both groups were treated in 4 stages,each of 5 consecutive days with intervals of 21 days.The Chinese Version of the Behavioral Assessment of Dysexecutive Syndrome (BADS) was used to evaluate both groups before and after the intervention,including rule transformation ability,problem solving ability,planning ability,supervising ability and organizing ability.Results After the intervention,the experimental group had a significantly higher average score than before the intervention in the rule-switching card test,the action planning test,the key-finding test,and the modified six-element test.Their average BADS score was also significantly improved.The control group showed a significantly better average score only in the key-finding test and in its average BADS total score.After the intervention,the experimental group had a significantly higher average score than the control group in the rule-switching card test and the action planning and six-element tests.Its average BADS rating was also significantly better.Conclusion Tomatis high and low frequency auditory training can improve the executive function of patients undergoing chemotherapy for breast cancer.Its effect is better than that of ordinary music training.

Objective To explore the correlation between polarization status of microglia/macrophages(MG/MP)in brain tissue and edema around hematoma in patients with acute cerebral hemorrhage.Methods A total of 52 patients with acute intracerebral hemorrhage admitted to Anyang People's Hospital from December 2020 to November 2022 were selected as the research subjects.All patients underwent craniotomy to remove hematoma,and the normal brain tissue in the cortical area that was not invaded by the hematoma and the fragmented brain tissue around the hematoma(brain tissue around the hematoma)on the surgical pathway were obtained.The expression levels of inflammatory factors such as interleukin(IL)-1β,IL-6,tumor necrosis factor-α(TNF-α),IL-10 and transforming growth factor-β(TGF-β)protein in brain tissue were detected by Western blot.The expression levels of IL-1 β,IL-6,TNF-α,IL-10 and TGF-β mRNA in brain tissue were detected by fluorescence quantitative polymerase chain reaction.The levels of M1-type and M2-type MG/MP in brain tissue was detected by immunofluorescence confocal technique.CT images data of patients before operation were collected and the relative-erihema-tomal edema(r-PHE)was calculated.The patients were divided into high r-PHE group(2.0≤ r-PHE＜2.5)and low r-PHE group(1.5＜r-PHE＜2.0)according to r-PHE.The relative expression of IL-1 β,IL-6,TNF-α,IL-10 and TGF-β mRNA in brain tissue around the hematoma of patients between the high r-PHE group and the low r-PHE group was compared.Results The relative expressions of IL-1 β,IL-6,TNF-α protein and mRNA in brain tissue around the hematoma were significantly higher than those in the normal brain tissues(P＜0.05),but there was no significant difference in the relative expressions of IL-10 and TGF-β protein and mRNA between the brain tissue around the hematoma and the normal brain tissue(P＞0.05).The levels of M1 type and M2 type MG/MP in the brain tissue around the hematoma were significantly higher than those in normal brain tissue(P＜0.05).The relative expressions of IL-1β,IL-6 and TNF-α mRNA in the brain tissue around the hematoma of patients in the high r-PHE group were significantly higher than those in the low r-PHE group(P＜0.05),and there was no significant difference in the relative expressions of TGF-β and IL-10 mRNA in the brain tissue around the hematoma of patients between the two groups(P＞0.05).Conclusion The levels of pro-inflammatory factors and M1-type MG/MP are increased in the brain tissue around the hematoma in patients with acute cerebral hemorrhage,and the degree of polarization of M1-type MG/MP is consistent with the degree of edema around hematoma after cerebral hemorrhage.

Objective To investigate the clinical efficacy of CT-guided 125I seeds implantation combined with gemcitabine + cis-platinum (GP) in the treatment of unresectable non-small cell lung cancer (NSCLC).Methods From January 2013 to January 2017,62 patients with unresectable Ⅱ b-Ⅲb NSCLC were randomly divided into 2 groups.In the study group,32 patients (17 males,15 females,age (62.7± 8.9) years) underwent 125I seeds implantation combined with 4 courses of GP chemotherapy,and 30 patients (18 males,12 females,age (61.9±7.0) years) in the control group underwent concurrent radiotherapy combined with 4 courses of GP chemotherapy.The short-term effects at 3 and 6 months after treatment were compared between 2 groups,as well as the survival time.Log-rank test was used to analyze the data.Results The effective rates at 3 and 6 months after treatment in the study group and control group were statistically significant (90.62％ (29/32) vs 70.00％ (21/30),96.88％ (31/32) vs 66.67％ (20/30);x2 values:3.00 and 7.22,both P＜0.05).The median survival time of the study group and control group were 17 and 15 months (x2 =2.194,P＞0.05).The 1-year survival rates of 2 groups were 87.50％ (28/32) and 76.67％ (23/30),respectively (x2=1.24,P＞0.05),and the 2-year survival rates were 40.62％ (13/32)and 20.00％(6/30),respectively (x2=4.00,P＜0.05).Conclusions 125I seeds implantation combined with GP chemotherapy is a significant treatment for unresectable NSCLC.The short-term efficacy is better than concurrent radiotherapy combined with GP regimen.

Objective:To analyze the value of maximum standardized uptake value (SUV max) of 18F-fluorodeoxyglucose (FDG) PET/CT in differentiating the malignant solitary pulmonary nodules (SPN) from benign ones. Methods:18F-FDG PET/CT imaging data of 84 patients (39 males, 45 females; age: 34-81(average: 61.1) years) with SPN in the First People′s Hospital of Lianyungang between September 2017 and June 2019 were retrospectively analyzed. The pathological results were taken as the gold standard. Differences of SUV max between benign and malignant SPN were analyzed with Mann-Whitney U test, and the best cut-off value for the diagnosis of benign and malignant SPN was measured by receiver operating characteristic (ROC) curve. The diagnostic efficacy was analyzed based on SUV max. Results:The pathological results confirmed 54 patients with malignant SPN, and 30 patients with benign SPN. SUV max of malignant group was significantly higher than that of benign group (5.48±4.08 vs 1.70(0.73, 3.33); U=443.50, P=0.001). The 84 SPN included 58 solid SPN and 26 subsolid SPN. SUV max of malignant subsolid SPN and benign ones were not significantly different ( U=56.00, P>0.05). The diagnostic value of SUV max in 58 cases of solid nodules were analyzed based on ROC curves, and the optimal cut-off value was 1.85. The corresponding diagnostic sensitivity, specificity, accuracy, negative predictive value and positive predictive value were 97.06%(33/34), 62.50%(15/24), 82.76%(48/58), 15/16, 78.57%(33/42), respectively. Conclusions:18F-FDG uptake of malignant SPN were higher than benign ones. The diagnosis of benign and malignant solid SPNs based on SUV max 1.85 has high sensitivity, negative predictive value and accuracy. SUV max has limited diagnostic value on subsolid SPN.

Objective:To explore the demand and mode of palliative care for emergency dying patients by analyzing the case data of emergency death and cardiopulmonary resuscitation.Methods:The data of 776 cases of emergency clinical death and cardiopulmonary resuscitation in the Second Affiliated Hospital of Soochow University from 2017 to 2020 were retrospectively analyzed.Results:A total of 687 patients were included with (70.38 ± 16.57) years old, and 49.8% (342/687) of them were 75 years old and above; among them, 36.0% (247/687) patients or their families chose not to give cardiopulmonary resuscitation (DNR) in the last stage of their lives,and 63.2%(156/247) of DNR patients were 75 years old and above. The top four etiology of DNR were cerebral hemorrhage, respiratory failure, multiple organ dysfunction syndrome and out of hospital cardiac and respiratory arrest.After successful cardiopulmonary resuscitation, 37.5% (45/120) of the patients' family members chose to give up treatment again. The median stay time of DNR patients in the emergency room was 738.7 minutes.Conclusions:The patients who choosed DNR were mainly 75 years old and above, with cerebral hemorrhage, respiratory failure, multiple organ failure and cardiac and respiratory arrest. The detention of these patients in the emergency room increases the congestion of the emergency room, and at the same time, they can not get a peaceful palliative care environment. It is suggested that emergency medical staff should strengthen the awareness and improve the ability of palliative care. A relative independent area and corresponding soothing palliative treatment and nursing should be given to the DNR patients.
