Objective To understand cognition level and treatment intention of patients with endometriosis(EMs);To evaluate the effects of TCM chronic disease management on EMs patients.Methods The disease cognition level and treatment intention of 1 895 EMs patients from October 2020 to December 2021 in 19 provinces,autonomous regions and municipalities were analyzed through cross-sectional investigation.The cognitive effect of chronic disease management of TCM on 801 patients with EMs from 6 Grade A hospitals in Beijing was evaluated by self-control study.Results The cognition level of EMs patients for the disease was improved with the increase of educational background.Patients generally believed that EMs was a chronic disease,requiring regular review and long-term management.The proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the possibility of malignant changes in EMs was less,only 32.3%,41.6%and 47.7%,respectively.The awareness rate of patients with high school education or below for recurrence after EMs conservative surgery was 46.9%,lower than that of those with junior college education(66.8%)and bachelor degree or above(72.7%).Among the patients with dietary contraindications,the proportion of patients with high school education or below,junior college education,bachelor degree or above who knew the contraindication of the forest frog oil was less,only 20.7%,30.3%and 32.9%,respectively.In the aspect of life adjustment,the awareness of patients was generally high.EMs patients mainly recognized the disease through face-to-face communication with gynecologists.Only 34.4%of patients with high school education or below learned about EMs through WeChat public accounts,APPs and other new media,which was lower than those with junior college education(48.6%)and bachelor degree or above(55.4%).EMs patients generally tend to be treated in comprehensive hospitals,with high acceptance of TCM treatment,mainly TCM decoction,and low acceptance of TCM appropriate technology.After 1 year of TCM chronic disease management,the disease awareness of EMs patients was significantly improved compared with before management,with statistical significance(P<0.05).Conclusion EMs patients with different educational backgrounds have different cognition of the disease,and each has different emphasis.Education and popularization should be carried out according to their knowledge blind spots.Chronic disease management of TCM can improve the disease cognition level of EMs patients.

Objective:To evaluate the role of ubiquitin-specific peptidase 22 (USP22) in myocardial ischemia-reperfusion (I/R) injury in diabetic mice.Methods:Seventy-eight SPF male C57BL/6 mice, aged 6-8 weeks, were divided into 6 groups using a random number table method: sham operation group (Sham group, n=12), type 1 diabetes mellitus + sham operation group (T1D+ Sham group, n=12), myocardial I/R injury group (I/R group, n=12), type 1 diabetes mellitus + myocardial I/R injury group (DI/R group, n=12), type 1 diabetes mellitus + myocardial I/R injury + empty vector group (DI/R+ V group, n=15), and type 1 diabetes mellitus + myocardial I/R injury + USP22 overexpression group (DI/R+ U group, n=15). Type 1 diabetes mellitus was induced by intraperitoneal injection of streptozotocin-citrate buffer. Myocardial I/R was induced by ligation of the left coronary artery. At 1 day before developing the myocardial I/R injury model, DI/R+ U group and DI/R+ V group received an intramyocardial injection of USP22 overexpression plasmid or empty vector plasmid, respectively. At 24 h of reperfusion, cardiac function was assessed using the echocardiography to measure the left ventricular ejection fraction and left ventricular fractional shortening. The mice were then sacrificed, and their hearts were harvested for measurement of the myocardial infarct size, for microscopic examination of pathological changes (using HE staining) and for determination of the apoptosis rate (TUNEL staining), reactive oxygen species(ROS) activity (DHE staining), and USP22 expression (by Western blot, immunofluorescence, and immunohistochemistry). Proteomic analysis was performed to identify downstream proteins regulated by USP22, and protein-protein interactions were investigated using co-immunoprecipitation. Results:Compared with Sham group, the cardiac function indices were significantly decreased, the apoptosis rate of myocardial cells and ROS activity were increased, and USP22 expression in myocardial tissues was down-regulated in I/R group ( P<0.05). Compared with I/R group, the percentage of myocardial infarct size was significantly increased, the cardiac function indices were decreased, the apoptosis rate of myocardial cells and ROS activity were increased, and USP22 expression in myocardial tissues was up-regulated ( P<0.05), and the pathological damage to myocardial tissues was aggravated in DI/R group. Compared with DI/R+ V group, the percentage of myocardial infarct size was significantly decreased, the cardiac function indices were increased, the apoptosis rate of myocardial cells and ROS activity were decreased, and USP22 expression in myocardial tissues was up-regulated ( P<0.05), and the pathological damage to myocardial tissues was alleviated in DI/R+ U group. The results of proteomics combined with co-immunoprecipitation experiments showed an interaction between calponin 1 and USP22. Conclusions:During myocardial I/R injury in diabetic mice, USP22 may act as an endogenous protective mechanism, and calponin 1 might be a downstream mechanism through which USP22 exerts its protective effects.

ObjectiveTo visualize the research trends of verbal and nonverbal cognitive functions in patients with post-stroke aphasia (PSA). MethodsPapers about verbal and nonverbal cognitive functions after stroke were extracted from Web of Science Core Collection from establishment to August, 2022, and a bibliometric analysis was conducted on the distribution of articles published by year, author, journal, institution, and country. Author cooperation, author co-citation, journal co-citation, country/institution cooperation, dynamic evolution, keyword hotspots, and trends were visually analyzed by using VOSviewer software. ResultsA total of 1 630 publications were identified for final analysis. The first article related to the topic was retrieved in 2004. After that, the number of published papers showed an increasing trend year by year, with some fluctuations after 2019. Matthew A. Lambon Ralph and Elizabeth Jefferies were the authors who produced the most, were cited the most, and were the most influential. Neuropsychologia was a highly productive and well-cited publication. The University of Manchester in the United Kingdom and Johns Hopkins University in the United States were the nations/institutions with high yield and high centrality. Although China had a high yield and was in the top five, the centrality was insufficient. The dynamic emergence of keywords revealed that the research had gone through the following stages: evaluating the mechanism of language and nonverbal cognitive function impairment based on neuroimage, exploring the role of nonverbal cognitive dysfunction in pathology and recovery mechanisms of patients with PSA, examining the therapeutic mechanism of non-invasive brain stimulation and electronic tele-rehabilitation equipment, and revealing not only the frontal and temporal areas but also brain network supporting nonverbal cognition. ConclusionIn recent years, some achievements have been made in the researches on verbal and nonverbal cognitive function, particularly in the studies of the neuroimaging-based mechanisms of common damage and the intervention effects of synergistic therapy. In the future, academic cooperation between different regions and different teams needs to be strengthened. Further exploration should be focused on refining the cognitive neuropsychology and exploring new technologies to improve the therapeutic effect of PSA.

Objective:Breast cancer has been the first cancer among women with the incidence increasing gradually. In September 2016, the Breast Cancer Cohort Study in Chinese Women (BCCS-CW) was initiated, aiming to establish a standardized and sharable breast cancer-specific cohort by integrating the existing cohort resource and improving the quality of follow-up.

The cohort was followed by using regional health surveillance and ad hoc survey.Results:Finally, BCCS-CW included 112 118 women, in which 55 419 women completed the standardized investigation and blood specimens were collected from 54 304 women. The mean age of participants was 51.7 years old, 62.7% were overweight or obese, and 48.9% were menopausal.Conclusion:The BCCS-CW will provide population-based cohort resource and research platform for the precise prevention and treatment of breast cancer in Chinese women.

This paper aims to explore a new way to cultivate college students' autonomous learning ability by taking the flipped classroom teaching of molecular medicine in medical colleges as an example. In view of the specific teaching content and characteristics of molecular medicine, we formulated a mixed teaching plan based on flipped classroom. By setting the teaching objectives and tasks beforehand, students were guided to explore and acquire knowledge independently from the abundant teaching resources library. In order to test the effect of students' autonomous learning and expand the cultivation of students' ability of information collection and processing, inquiry initiation, and communication and cooperation, we launched classroom discussions, communications, questions answering and group collaborative research topic-based reports. Through the reform of teaching assessment system, students' autonomous learning status can be effectively monitored to help ensure the implementation of the flipped classroom.
