OBJECTIVE: To observe the effects of moxibustion at different temperatures on cognitive function and blood glucose levels in patients with cognitive impairment associated with type 2 diabetes mellitus (T2DM). METHODS: A total of 66 T2DM patients with cognitive impairment were randomly assigned to a high-temperature group (22 cases, 1 case dropped out, 1 case was eliminated), a medium-temperature group (22 cases, 2 cases were eliminated), and a low-temperature group (22 cases, 2 cases were eliminated). All groups received moxibustion at Baihui (GV20), Dazhui (GV14), and Shenting (GV24) based on their existing glycemic control treatment. Moxibustion temperatures were maintained at 44-46 ℃ (high-temperature group), 41-43 ℃ (medium-temperature group), and 38-40 ℃ (low-temperature group), respectively, for 20 min per session, every other day, 3 times a week for 3 months. The Montreal cognitive assessment (MoCA) score, mini-mental state examination (MMSE) score, short-term memory (STM) accuracy and average reaction time, Rey-Osterrieth complex figure (ROCF) score, fasting plasma glucose (FPG), and glycated hemoglobin (HbA1c) were assessed before and after treatment. Clinical efficacy was evaluated after treatment. RESULTS: After treatment, MMSE scores in all three groups were higher than those before treatment (P<0.05). In the high-temperature group, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, naming, language, and abstraction were higher than those before treatment (P<0.05); the scores of ROCF copy, immediate recall, and delayed recall were higher than those before treatment (P<0.05); the HbA1c level was lower than that before treatment (P<0.05). In the medium-temperature group, the total MoCA score and the scores of memory and delayed recall, attention, and language were higher than those before treatment (P<0.05). STM accuracy was higher than before treatment (P<0.05), and STM average reaction time was shorter than before treatment (P<0.05) in both the high-temperature and medium-temperature groups. After treatment, the total MoCA score and the scores of visuospatial and executive function, memory and delayed recall, attention, and language in the high-temperature group were higher than those in the medium- and low-temperature groups (P<0.05); MMSE score, STM accuracy, and ROCF immediate recall and delayed recall scores were higher than those in the medium- and low-temperature groups (P<0.05); STM average reaction time was shorter than that in the medium- and low-temperature groups (P<0.05); HbA1c level was lower than that in the low-temperature group (P<0.05). The total MoCA score, attention score, and MMSE score in the medium-temperature group were higher than those in the low-temperature group (P<0.05), and STM average reaction time was shorter than that in the low-temperature group (P<0.05). There were no statistically significant differences in FPG within or between the three groups before and after treatment (P>0.05). The total effective rates were 75.0% (15/20) in the high-temperature group, 50.0% (10/20) in the medium-temperature group, and 15.0% (3/20) in the low-temperature group; the total effective rate in the high-temperature group was significantly higher than that in the low-temperature group (P<0.05). CONCLUSION Moxibustion at different temperatures has a dose-effect relationship in treating cognitive impairment in T2DM patients. A temperature range of 44-46 ℃ is more effective in improving cognitive function and stabilizing average blood glucose levels over 2-3 months.

With the rapid development of artificial intelligence, computational pathology has been seamlessly integrated into the entire clinical workflow, which encompasses diagnosis, treatment, prognosis, and biomarker discovery. This integration has significantly enhanced clinical accuracy and efficiency while reducing the workload for clinicians. Traditionally, research in this field has depended on the collection and labeling of large datasets for specific tasks, followed by the development of task-specific computational pathology models. However, this approach is labor intensive and does not scale efficiently for open-set identification or rare diseases. Given the diversity of clinical tasks, training individual models from scratch to address the whole spectrum of clinical tasks in the pathology workflow is impractical, which highlights the urgent need to transition from task-specific models to foundation models (FMs). In recent years, pathological FMs have proliferated. These FMs can be classified into three categories, namely, pathology image FMs, pathology image-text FMs, and pathology image-gene FMs, each of which results in distinct functionalities and application scenarios. This review provides an overview of the latest research advancements in pathological FMs, with a particular emphasis on their applications in oncology. The key challenges and opportunities presented by pathological FMs in precision oncology are also explored.

Objective: To explore the network structure characteristics and core items of rural middle school students suffering from campus bullying and anxiety symptoms, so as to provide a reference basis for the precise prevention and intervention of the comorbidity of campus bullying and anxiety symptoms. Methods: From September 2021 to March 2022, a multi stage random cluster sampling method was used to select 1 920 rural middle school students from Xuzhou. The Chinese version of the Olweus Bully/Victim Questionnaire was used to investigate the situation of campus bullying, and the Chinese version of the Generalized Anxiety Disorder (GAD-7) was used to assess anxiety symptoms. The network analysis method was used to construct the network between suffering from campus bullying and anxiety symptoms of rural middle school students to evaluate the centrality, bridge strength, stability and accuracy of each item. Results: The total score of suffering from campus bullying symptoms of rural middle school students was (10.42±3.26) points, and the total score of anxiety symptoms was (11.47±4.93) points. The symptom with the highest strength and expected influence was "unable to stop or control one s worry emotions", and the node strength and expected influence value was 1.041 7. The nodes "feel nervous, anxious or irritable" and "unable to stop or control one s worry emotions" were most closely related. The symptoms with the highest bridge strength were "others give me ugly nicknames to scold me or make fun of and satirize me" and "unable to stop or control one s worry emotions". Conclusions Rural middle school students suffering from campus bullying is related to anxiety symptoms. Accurate intervention according to the intervention targets may minimize the negative impact of suffering from campus bullying and anxiety symptoms on rural middle school students.

Objective:To study the overall training effect of segmented training model on key fiberoptic bronchoscopy techniques for anesthesiology residents and the influence of key technique training order on the training effect.Methods:Different fiberoptic bronchoscopy simulators were used for specialized training in different key techniques of fiberoptic operation. To examine the effect of key technique learning order on the teaching effect, 40 anesthesiology residents who participated in fiberscope simulation training at Ruijin Hospital, Shanghai Jiaotong University School of Medicine between November 2022 and March 2023 were selected for this study. They were randomly divided into two groups (Group S and Group M) using a numerical table method. The teaching was completed using two orders of key techniques. The operation time, operation quality score, and theoretical knowledge mastery score of the two groups were recorded to compare the effect of key technique learning order on the mastery of fiberoptic skills. SPSS 29.0 statistical software was used for data analysis. Measurement data that conformed to normal distribution were expressed as mean ± standard deviation, and the independent samples t-test or Fisher's exact test were used for comparison between groups. The chi-square test was used for comparison of enumeration data. Results:After segmented training in each key technique, both groups of trainees were able to shorten the operation time of the corresponding key technique [SM simulator operation time (132.25±14.69) s vs. (49.80±4.46) s in group S, P<0.01; M simulator operation time (82.30±11.60) s vs. (57.10±6.77) s in group S, P<0.01; SM simulator operation time (83.10±10.62) s vs. (52.10±5.20) s in group M, P<0.01; M simulator operation time (132.25±14.69) s vs. (55.40±5.91) s in group M, P<0.01)]. Moreover, both groups showed a reduced number of wall touches [SM simulator wall touches (3.35±0.93) times vs. (0.65±0.49) times in group S, P<0.01; M simulator wall touches (2.50±1.05) times vs. (0.70±0.80) times in group S, P<0.01; SM simulator wall touches (1.55±1.15) times vs. (0.40±0.50) times in group M, P<0.01; M simulator wall touches (5.90±1.29) times vs. (1.10±0.79) times in group M, P<0.01]. There were no significant differences between the two groups in the performance score of fiberoptic-guided tracheal intubation after training [(92.50±5.97) points vs. (91.75±5.45) points] and in the lung segment localization time [(23.15±4.39) s, (21.40±4.84) s, (22.85±4.42) s vs. (22.75±5.11) s, (21.00±5.40) s, (21.50±5.10) s]. Conclusions:Segmented training on key fiberoptic bronchoscopy techniques is an effective model of fiberscope training for anesthesiology residents, and the order of training key techniques does not affect the effectiveness of training.

Objective:To investigate the effect of modified percutaneous closure in the treatment of ventricular septal rupture.Methods:This study is a retrospective cohort study. Forty-four patients with ventricular septal rupture who underwent percutaneous closure at the Fuwai Central China Cardiovascular Hospital from December 2017 to October 2023 were included. According to the closure method, patients were divided into the modified group (11 cases) and the traditional group (33 cases). Surgical success was defined as successful placement of the occluder. The operation time, X-ray intake, sheath bending rate, incidence of ventricular fibrillation and pericardial tamponade, and postoperative residual shunt were compared between the two groups.Results:The age of the patients was (75.0±5.7) years, with 20 (45%) males. There were 3 cases of operation failure in the traditional group, while all patients in the modified group were successfully occluded. The procedure time in the modified group was shorter than that in the traditional group (40 (35, 45) min vs. 60 (50, 65)min, P<0.001); X-ray dose intake was lower ((442.43±73.26)mGy vs. (784.45±247.78)mGy, P<0.001). There was no occurrence of sheath bending in the modified group, while the incidence of sheath bending in the traditional surgery group was 46% (15/33), and the difference was statistically significant ( P=0.017). Intraoperative ventricular fibrillation and pericardial tamponade occurred in 7 cases (21%) and 2 cases (6%) in the traditional group respectively, while none occurred in the modified group, but the differences between the groups were not statistically significant (both P>0.05). There was no significant difference in residual shunt between the two groups (3.6 (2.5, 4.3) mm vs. 4.0 (3.5, 4.5) mm, P=0.506). Conclusion:The procedure of modified ventricular septal rupture closure is more simplified, with a lower incidence ofventricular fibrillation and pericardial tamponade.

Objective:To investigate the early effect of repairing acetabular cartilage delamination with absorbable anchor under hip arthroscopy compared with conventional non-intervention.Methods:Retrospective cohort study was adopted. There were 24 Femoroacetabular Impingment (FAI) patients with acetabular cartilage delamination (ACD) receiving hip arthroscopy surgery in Peking University Third Hospital from May 2021 to August 2021. There were 14 males and 10 females with an average age of 36.3±7.2 years (range 23-53 years). There were 12 patients receiving acetabular cartilage repair with absorbable anchor (absorbable anchor group), and 12 patients in non-intervention group. The X-ray film indicators, α angle, lateral center edge angle (LCEA) and MRI measurement (acetabular cartilage gap, CG) were compared between the two groups. The pre- and post-operative hip functions were assessed by modified Harris Hip Score (mHHS), 12-item international hip outcome tool (iHOT12), hip outcome score-activities of daily living subscale (HOS-ADL), and hip outcome score-sports subscale (HOS-SS), along with visual analogue scale (VAS). The complications (infection, lower extremity deep venous thrombosis) were followed up, as well as the revisional hip arthroscopy surgery and total hip replacement surgery.Results:A total of 24 patients were followed up for 12.0±1.2 months (range 10-14 months). There was no significant difference between the two groups for age, BMI, and symptom onset time ( P>0.05). There was no significant difference between the two groups for the pre-operative α angle, LCEA, CG, mHHS, iHOT12, HOS-ADL, HOS-SS, and VAS scores ( P>0.05). At the last follow-up, there was no significant difference between the two groups for the α angle, LCEA, CG, mHHS, iHOT12, HOS-ADL, HOS-SS, VAS and satisfaction ( P>0.05). In the absorbable anchor group, the α angle was 47.2°±2.6° vs. 63.4°±3.3°, CG was 3.0±0.7 mm vs. 3.3±0.6 mm; mHHS was 73.6±16.0 vs. 57.7±15.4; iHOT12 was 67.6±22.5 vs. 50.6±15.0 after and before the surgery, with significant improvement ( P<0.05). As for the non-intervention group, there was significant decrease of post-operative α angle of 47.4°±2.6° compared to the pre-operative angle of 58.4°±8.1° ( P<0.05). There was no significant difference in LCEA, CG, mHHS, iHOT12, HOS-ADL, HOS-SS, and VAS scores before and after the surgery in non-intervention group comparison ( P>0.05). No complications, revision hip arthroscopy surgery or total hip replacement surgery occurred during the follow up. Conclusion:Good effect was yielded for absorbable anchor repairing acetabular cartilage delamination under hip arthroscopy, without additional risk of complications or revision surgery.

Objective:To explore the association between changes in brain structural network during the early stage of stroke recovery and the onset of post-stroke depression (PSD).Methods:A total of 87 acute ischemic stroke patients scheduled for discharge, who were admitted to the Yixing Hospital Affiliated to Jiangsu University from March 2020 to May 2021, were prospectively collected. During the same period, 34 healthy control subjects matched with the stroke patients were also collected. All participants underwent systematic magnetic resonance imaging scans and scale assessments, and were followed up longitudinally for 2 years. Based on the occurrence of depression during follow-up, the stroke patients were divided into PSD group and post-stroke non-depression (PSND) group. Graph theoretical analysis was used to analyze the topological characteristics of brain structural network. Analysis of variance was used to explore the differences in brain structural network attributes among groups. Logistic regression model was used to analyze the predictive power of differential brain network attributes for PSD. Linear regression analysis was conducted to investigate the relationship between the synergism of non-rich-club regions and changes in rich-club connectivity.Results:The rich-club connectivity and synergism of the non-rich-club regions were significantly lower in the PSD group than in the PSND group (rich-club connectivity, P<0.01; synergism of feeder/local, P<0.001). The regression model demonstrated that the synergism of non-rich-club regions had a good predictive power for the occurrence of PSD ( OR=1.195, 95%CI 1.073-1.471, P<0.001). Furthermore, linear regression analysis revealed a significant correlation between the synergism of non-rich-club regions and Δrich-club connectivity ( r=-0.691, P<0.001). Conclusion:The good synergism of non-rich-club regions during the early stage of stroke recovery promotes the repair of rich-club connectivity and inhibits the onset of PSD.

Objectives:To verify the reliability and validity of the frailty assessment scale for elderly patients with inguinal hernia and to evaluate the value of its clinical application.Methods:A convenience sampling method was used to collect 129 geriatric patients who underwent inguinal hernia surgery from January 2018 to January 2023 in nine hospitals in Liaoning Province. There were 120 males and 9 females, of whom 89 patients were 60 to <75 years old, 33 patients were 75 to <85 years old and 7 patients were ≥85 years old. The 129 patients included 11 elderly patients with inguinal hernia who had recovered from preoperative infection with COVID-19. Statistical methods such as Cronbach′s coefficient, Kaiser-Meyer-Olkin test, Bartlett′s test, Pearson′s correlation analysis, etc. were calculated to verify the reliability indexes such as feasibility, content validity, structural validity, criterion-related validity, internal consistency reliability, and re-test reliability. Taking the 5-item modified frailty index (5-mFI) as the gold standard, the area under the curve was used to analyze the ability of the two scales to predict the occurrence of postoperative acute urinary retention, postoperative delirium, poor incision healing, operative hematoma seroma, and postoperative complications.Results:The frailty assessment scale for elderly patients with inguinal hernia showed good reliability and validity (valid completion rate of 99.2%; item content validity index of 1.000, and the scale content validity index of 1.000; exploratory factor analysis extracted a total of 1 principal component, and factor loadings of each item of 0.565 to 0.873; the AUC for frailty diagnosis using 5-mFI as the gold standard of 0.795 ( P<0.01) Cronbach′s coefficient of 0.916, retest reliability coefficient of 0.926), it could effectively predict postoperative acute urinary retention, delirium, hematoma seroma in the operative area and total complications (AUC of 0.746, 0.870, 0.806, and 0.738, respectively; all P<0.05), and prediction efficiency was higher than that of 5-mFI (AUC of 0.694, 0.838, 0.626 and 0.641, P<0.05 for delirium only), but both scales were inaccurate in predicting poor incision healing (AUC of 0.519, P=0.913 for the frailty assessment scale and 0.455, P=0.791 for the 5-mFI). Conclusions:The frailty assessment scale for elderly patients with inguinal hernia is reliable and significantly predicts the occurrence of postoperative adverse events in elderly inguinal hernia patients. The scale can also be used for preoperative frailty assessment in elderly patients with inguinal hernia after rehabilitation from COVID-19 infection.
