Objective:To understand the current status of the use of aspirin in perioperative period of thoracic surgery in China and the awareness of thoracic surgeons on the prevention and treatment of arterial thromboembolic diseases during the perioperative period.Methods:A survey was conducted among thoracic surgeons nationwide using an electronic questionnaire through a software platform from January 20, 2024 to February 29, 2024. The questionnaire mainly included three parts: basic information, aspirin use, and awareness of arterial thromboembolic diseases, with a total of 27 questions.Results:A total of 1318 valid questionnaires were collected, covering all 33 provincial administrative regions except Taiwan. 69.7%(919/1 318) of thoracic surgeons stopped using aspirin for all patients before surgery; differences could be found in the timing of aspirin withdrawal before surgery and resumption after surgery. 65.1%(858/1 318) of surgeons made perioperative medication decisions based on domestic guidelines or consensus, while 20.9%(276/1 318) of surgeons based their decisions on departmental or personal experience. 87.9%(1 159/1 318) of surgeons believed that it is necessary to develop guidelines for the prevention of arterial thromboembolic diseases in the perioperative period of thoracic surgery.Conclusion:The current use strategy of aspirin in the perioperative period of thoracic surgery in China shows a high degree of inconsistency, and there are also significant differences in the awareness of arterial thromboembolic diseases. It is necessary to establish guidelines for the prevention and treatment of arterial thromboembolic diseases in the perioperative period.

Objective To compare the success rates of different culture methods for hemorrhagic amniotic fluid.Methods Thirty-one hemorrhagic amniotic fluid samples from pregnant women who were subjected to chromosomal examination at Anhui Maternal and Child Health Hospital were collected from January 2021 to December 2022.Two culture methods,the slide in situ culture box method(re-ferred to as the slide method)and the plastic bottle culture combined with slide in situ culture box method(referred to as the combined culture method),were used for cell cultivation.All the cells were harvested and stained with Giemsa staining,then the number of eligi-ble karyotype was counted and the success rates were compared between the two methods.Results Among the 31 cases of the slide method,21 were successfully cultured with a success rate of 67.7％.For the combined culture method,all the 31 cases were success-fully cultured with a success rate of 100％.The success rate of the combined culture method was significantly higher than that of the slide method(P＜0.05).Of 31 bloody amniotic fluid samples,three cases were fresh bleeding,and an average number of eligible kary-otype was 8 in the slide method and 32 in the combined culture method.Twenty-eight cases were old bleeding,and an average number of eligible karyotype was 13 in the slide method and 53 in the combined culture method.The number of eligible karyotype in the com-bined culture method was significantly higher than that of the slide method(P＜0.05).Conclusion The combined culture method is suitable for the cultivation of hemorrhagic amniotic fluid samples,and should be worthy of promotion in the clinics.

  Objective  To analyze the current status of the development of adaptation guidelines in China, as well as their methodological quality and the reporting quality, in order to provide reference for the development of adaptation guidelines.  Methods  We searched and collected adaptation guidelines led by Chinese researchers or institutions from 2015 to 2023 from four electronic databases, China National Knowledge Infrastructure, WanFang Data Knowledge Service Platform, SinoMed and PubMed, extracted the basic information of the adapted guidelines, and assessed their methodological quality and reporting quality using the Appraisal of Guidelines for REsearch and Evaluation (AGREE) Ⅱ and RIGHT-Ad@pt tools.  Results  A total of 14 adaptation guidelines were included, mainly focusing on nursing (42.9%, 6/14), with the most frequently used adaptation method of ADAPTE (71.4%, 10/14), and with reference to pre-existing guidelines mainly from the United States, the United Kingdom, and international organizations. Assessment by the AGREE Ⅱ tool showed that the average methodological quality score of the adapted guidelines was 36.6%. The scores were relatively high in the domains of clarity of expression and rigor of formulation (44.4% and 54.9%), and lowest in the domain of applicability (15.3%). The results of the RIGHT-Ad@pt tool showed that the reporting quality of the adaptation guidelines was relatively good, with the highest reporting rate of 91.2% and the lowest of 35.3%, and the reporting rates of seven articles were higher than 70%.  Conclusions  Adaptation guidelines in China are still in their infancy, with a relatively small number and mainly focusing on the nursing field. The most commonly used adaptation method is the ADAPTE method. The methodological quality and reporting quality of adaptation guidelines need to be further improved, and more research should be conducted on the specific conditions and timing of adaptation guidelines development.

Purpose To study the relationshiPbetween CD88 expression and clinicopathologic features and epithelial-mesenchymal transition(EMT)in esophageal squamous cell carcinoma.Methods TCGA and TIMER database were used to analyze the expression level of CD88 in esophageal squamous cell carcinoma and adjaecnt esophageal squamous cell epithelium and its relationship with epithelial-mesenchymal transition.Par-affin specimens were collected from 199 patients with clinically diagnosed esophageal squamous cell carcinoma.Immunohisto-chemical EnVision method was used to detect the expression of CD88 and EMT-related proteins in esophageal squamous cell carcinoma and adjacent tissues,the relationship between CD88 expression and clinicopathological features,prognosis and EMT in ESCC tumors was analyzed.Results There were 86 cases with high CD88 expression and 113 cases with low CD88 expres-sion.The expression level of CD88 in esophageal squamous cell carcinoma was significantly higher than that of paracancerous tis-sue(P＜0.001).The group with high CD88 expression had lower ESCC differentiation level(P＜0.001)and higher T stage(P=0.03).The 5-year survival of patients with high CD88 ex-pression was significantly lower than that of patients with low CD88 expression(P=0.002).Cox univariate and multivariate analysis showed that CD88 expression was an independent prog-nostic factor for overall survival of patients with esophageal squa-mous cell carcinoma(P=0.013).The high expression of CD88 was negatively correlated with E-cadherin(r=-0.146,P=0.039),and positively correlated with vimentin(r=0.387,P=1.61e-08)and N-cadherin(r=0.304,P=1.3e-05).Con-clusion CD88 is highly expressed in esophageal squamous cell carcinoma.CD88 may affect the occurrence,development,in-vasion and metastasis of esophageal squamous cell carcinoma through EMT,and it might be used as a prognostic marker for e-sophageal squamous cell carcinoma patients.

Objective:To investigate the predictive effect of perioperative depression and anxiety symptoms in breast cancer patients on the fear of cancer recurrence.Methods:A total of 194 patients with breast cancer during perioperative period from May 2019 to May 2020 in Qilu Hospital of Shandong University were selected. The depression, anxiety and fear of cancer recurrence were investigated by the general information questionnaire, the Generalized Anxiety Disorder-7 (GAD-7), the Patient Health Questionnaire-9 (PHQ-9) and the Fear of Progression Questionnaire-Short Form (FOR-Q-SF) at admission and two weeks after surgery, respectively.Results:Perioperative depression and anxiety symptoms of breast cancer patients were significant predictors of fear of cancer recurrence ( B value was 2.325, OR value was 10.22, P<0.05; B value was 2.570, OR value was 13.07, P<0.05), and patients with depression and anxiety symptoms after surgery were at higher risk of fear of cancer recurrence ( OR values were 7.653-25.403, P<0.01). Conclusions:For breast cancer patients with negative emotions and fear of disease progression, it is necessary to help them improve their psychological coping ability, encouraging patients to actively cooperate with follow-up treatment, improving the prognosis, and improving their overall quality of life.

Objective To explore the diagnostic value of MR elastography and diffusion?weighted imaging in patients with liver fibrosis in the context of chronic hepatitis B. Methods Twenty?four patients with chronic hepatitis B, whose course of liver disease was more than 6 months and hepatitis B surface antigen was positive, were prospectively enrolled in the First Affiliated Hospital of Soochow University from July to December 2017. All of the patients underwent abdominal transient elastography (TE), routine MRI, magnetic resonance elastography (MRE) and DWI examination, TE and MRI were performed within one week. TE liver stiffness was measured, the MRE liver stiffness and ADC value were measured on MR imagings. All patients were divided into three groups: mild and non fibrosis (F0 to 1), significant fibrosis(F2 to 3) and cirrhosis (F4), according to the recommended standard of FibroTouch. Correlation between TE liver stiffness, MRE liver stiffness and ADC values were identified by using Spearman correlation test. The difference of the MRE liver stiffness and ADC value among the three groups was tested using independent sample t test. The overall predictive ability of MRE and DWI in assessment of liver fibrosis and cirrhosis was analyzed by constructing ROC curve. Results TE and MRI were successfully performed in all subjects, and the image quality was good. The MRE liver stiffness in mild and non fibrosis, significant fibrosis and cirrhosis was (2.32±0.31),(3.43±1.05),(4.77±0.68) kPa with statistically significant difference(F=61.690, P<0.01). The ADC values in three groups were (1.31 ± 0.14)×10-3, (1.23 ± 0.15)×10-3,(1.22±0.12)×10-3mm2/s without significant difference(F=1.074,P=0.360). The TE liver stiffness in three groups was (5.61±1.05),(9.56±0.57),(17.25±3.55)kPa, respectively, there was significant correlation between the MRE liver stiffness and the TE liver stiffness(t=0.858, P<0.01), but no significant correlation between the TE liver stiffness and the ADC value was found (r=-0.326,P=0.120). The area under ROC of MRE liver stiffness in diagnosing liver fibrosis grade (≥F2 and F4) was 0.96 and 1.00 respectively, while the AUC of ADC value was less than 0.70, which were 0.67 and 0.62 respectively. Conclusion MRE is a non?invasive promising tool for assessing liver fibrosis with chronic hepatitis B, while DWI has limited role.

Objective To exam the quality of life of the caregivers of patients with breast cancer, to explore their related factors, including medical characteristics of the patients, demographic characteristics of the caregivers, relationship with the patients, social support and psychological resilience, and to test the mediating and moderating roles of psychological resilience between social support and quality of life. Methods A total of 179 hospitalized patients diagnosed with breast cancer were recruited in Qilu Hospital of Shandong University. The self-designed demographic questionnaire, Medical Outcome Study 12-Item Short Form Health Survey,Version 2(SF-12V2), Perceived Social Support Scale(PSSS), and 10-item Connor-Davidson Resilience Scale(CD-RISC-10) were used to collect information about demographic characteristics and measure the quality of life, perceived social support and psychological resilience of the caregivers. The factors affecting the quality of life of the caregivers were analyzed by multiple linear regression analysis, and the mediating and regulating effects of mental resilience on social support and mental health were analyzed. Results The age of the caregivers was negatively correlated with the physical health (P=0.010). The score of the body health of the family members of the middle and late stage cancer patients was lower than that of the family members in the early stage (P=0.003). There was a positive correlation between friend support and resilience and mental health (P<0.01). Resilience played a moderating role and mediating role in the relationship between friend support and mental health. Conclusions Attention should be paid to the quality of life of caregivers in patients with breast cancer. The medical staff should provide more social support for the caregivers, and should pay more attention to improve the psychological resilience of the caregivers, guide them to better cope with the burden and pressure of care, and improve their mental health with half the effort.

Objectives: The purpose of this study is to understand the relationships among plasma glucose, blood pressure level and Traditional Chinese Medicine (TCM) syndromes in Shanghai community residents, and provide a theoretical basis for the prevention of community chronic disease based on TCM syndrome differentiation.Methods: Residents above35 years old will attend the Type 2 Diabetes Mellitus (T2 DM) risk assessment at Community Health Center. By distributing questionnaires and performing glucose testing, we screened the residents at high risk of T2 DM, and conducted a physical examination of them. Further, a body constitution questionnaire was required to be completed by the residents. Results: In total, 933 residents were screened. The plasma glucose and blood pressure levels related to age, waist circumference, hip circumference, body mass index (BMI) and waist-to-height ratio (WHtR) . Residents with increasing blood pressure have an increased risk of T2 DM (P ＜ 0.01) . Total 529 questionnaires were completed, and 129 subjects (24.4％) have single TCM syndromes, 75 subjects (14.2％) have at least two TCM syndromes and 325 subjects (61.4％) have no TCM syndromes. Conclusion: Plasma glucose and blood pressure are associated and interacted with several physical indexes. TCM syndromes distribution was found no significant change among subjects with different plasma glucose and blood pressure.
