Massive Open Online Courses （MOOCs） in medical ethics play a significant role in cultivating the humanistic quality of medical students. Through quantitative analysis， this paper compared the commonalities and differences in “medical ethics” MOOC courses in different types of colleges and universities， as well as proposed new paths for optimizing the cultivation of medical students’ humanistic quality. By searching and analyzing course data from “medical ethics” offered on mainstream MOOC platforms in China from 2013 to 2024， this paper explored new paths for the integration of MOOCs and humanistic quality from the perspectives of course content， faculty construction， student participation， and comparison between traditional Chinese medicine （TCM） universities and comprehensive universities. This study found that medical MOOCs focused on theoretical foundations and medical professional ethics and spirit， medical equity and social responsibility， as well as end-of-life care and medical humanistic care， forming a multidimensional curriculum system. Faculty teams reflected interdisciplinary characteristics， gathering teachers from disciplines such as medicine， philosophy， and education. Differences were observed between TCM universities and comprehensive universities. The former focused more on the origins and inheritance of humanistic care in TCM culture and ancient Chinese medical classics， while the latter emphasized more on Western ethical spirit. This paper can provide valuable insights for the diversified development of medical humanistic quality education， contribute to the integration of TCM ethics with modern medical ethics， provide references for online medical ethics education， implement new medical concepts， promote interdisciplinary integration of medicine and the humanities， and assists the reform and development of medical education.

This study aims to explore the medication rules and mechanisms of treating chronic renal failure(CRF) by Jinling medical school based on data mining, network pharmacology, and experimental validation systematically and deeply. Firstly, the study selected the papers published by the inherited clinicians in Jinling medical school in Chinese journals using the subject headings named "traditional Chinese medicine(TCM) + chronic renal failure", "TCM + chronic renal inefficiency", or "TCM + consumptive disease" in China National Knowledge Infrastructure, Wanfang, and VIP Chinese Science and Technology Periodical Database and screened TCM formulas for treating CRF according to inclusion and exclusion criteria. The study analyzed the frequency of use of single TCM and the four properties, five tastes, channel tropism, and efficacy of TCM used with high frequency and performed association rule and clustering analysis, respectively. As a result, a total of 215 TCM formulas and 235 different single TCM were screened, respectively. The TCM used with high frequency included Astragali Radix, Rhei Radix et Rhizoma, Salviae Miltiorrhizae Radix et Rhizoma, Poria, and Atractylodis Macrocephalae Rhizoma(top 5). The single TCM characterized by "cold properties, sweet flavor, and restoring spleen channel" and the TCM with the efficacy of tonifying deficiency had the highest frequency of use, respectively. Then, the TCM with the rules of "blood-activating and stasis-removing" and "diuretic and dampness-penetrating" appeared. In addition, the core combination of TCM [(Hexin Formula, HXF)] included "Astragali Radix, Rhei Radix et Rhizoma, Poria, Salviae Miltiorrhizae Radix, and Angelicae Sinensis Radix". The network pharmacology analysis showed that HXF had 91 active compounds and 250 corresponding protein targets including prostaglandin-endoperoxide synthase 2(PTGS2), PTGS1, sodium voltage-gated channel alpha subunit 5(SCN5A), cholinergic receptor muscarinic 1(CHRM1), and heat shock protein 90 alpha family class A member 1(HSP90AA1)(top 5). Gene Ontology(GO) function analysis revealed that the core targets of HXF predominantly affected biological processes, cellular components, and molecular functions such as positive regulation of transcription by ribonucleic acid polymerase Ⅱ and DNA template transcription, formation of cytosol, nucleus, and plasma membrane, and identical protein binding and enzyme binding. Kyoto Encyclopedia of Genes and Genomes(KEGG) analysis revealed that CRF-related genes were involved in a variety of signaling pathways and cellular metabolic pathways, primarily involving "phosphatidylinositol 3-kinase(PI3K)-protein kinase B(Akt) pathway" and "advanced glycation end products-receptor for advanced glycation end products". Molecular docking results showed that the active components in HXF such as isomucronulatol 7-O-glucoside, betulinic acid, sitosterol, and przewaquinone B might be crucial in the treatment of CRF. Finally, a modified rat model with renal failure induced by adenine was used, and the in vivo experimental confirmation was performed based on the above-mentioned predictions. The results verify that HXF can regulate mitochondrial autophagy in the kidneys and the PI3K-Akt-mammalian target of rapamycin(mTOR) signaling pathway activation at upstream, so as to alleviate renal tubulointerstitial fibrosis and then delay the progression of CRF.

Objective:To investigate the relationship between non-alcoholic fatty liver disease(NAFLD) and hepatic fibrosis and skeletal muscle mass in patients with type 2 diabetes mellitus(T2DM).Methods:A total of 685 T2DM patients diagnosed at the Endocrinology department of Lanzhou University First Hospital, from April 2022 to May 2023, were divided into NAFLD and Non-NAFLD groups, and the NAFLD group was further categorized into fibrosis and non-fibrosis based on aspartate aminotransferase(AST) /alanine aminotransferase(ALT) level. The differences in appendicular skeletal muscle mass(ASM), appendicular skeletal muscle mass index(ASMI), and the prevalence of muscle mass loss were compared across groups. The correlations between ASMI and NAFLD, as well as liver fibrosis were analyzed by binary logistic regression.Results:Among male T2DM patients, those with NAFLD had lower ASMI levels and a higher prevalence of muscle mass reduction compared to non-NAFLD group. Among female T2DM patients, those with NAFLD had lower levels of ASM and ASMI, and a higher prevalence of muscle mass reduction compared to non-NAFLD group. ASMI levels in both male and female T2DM patients were independently negatively correlated with NAFLD risk( OR=-0.696, 95% CI 0.579-0.837; OR=-0.757, 95% CI 0.629-0.911). In NAFLD patients, ASM and ASMI levels were lower in those with liver fibrosis compared to those without fibrosis; however, the prevalence of muscle mass reduction did not differ significantly. Among male NAFLD patients, ASMI levels were independently negatively correlated with the risk of liver fibrosis( OR=-0.726, 95% CI 0.537-0.983), while no correlation was found in female patients. Conclusion:Reduced muscle mass is independently associated with the risk of NAFLD in both male and female T2DM patients. In males, reduced muscle mass is also independently related to the risk of liver fibrosis.

Objective To analyze the current situation and latent profiles of nurses'voice behavior in nurses,and explore the influencing factors of different types.Methods Through convenience sampling,812 nurses who worked in tertiary hospitals from 5 cities in Guangdong Province during April 2022 to June 2022 were recruited.The demographic questionnaire,the Voice Behavior Scale,the Humble Leadership Scale,and the Team Psychological Safety Climate Scale were used for investigation.Latent profile analysis was used to explore the latent profiles of nurses'voice behavior.The influencing factors of latent profiles were identified by multivariate Logistic regression.Results The total score of the voice behavior in 812 nurses is(37.04±5.88).Voice behaviors in nurses is divided into 3 latent classes,namely"conservation group"(27.83％),"balanced-risky group"(61.95％),and"the challenge group"(10.22％).The influencing factors include recruitment type,whether to assist in department management,humble leadership,team psychological safety climate(all P＜0.05).Conclusion The level of nurses'voice behavior is upper medium with heterogeneity,which can be divided into 3 latent profiles.Nurses managers should focus on nurses with conservation group and balanced-risky group and conduct early targeted prevention and care according to characteristics and influencing factors of different latent profile.

ObjectiveTo explore the possible mechanisms of Shoutai Wan （寿胎丸） in treating recurrent miscarriage （RSA） from the perspective of immune tolerance under the acidic microenvironment at the maternal-fetal interface. MethodsFemale CBA/J mice were randomly divided into normal group， model group， progesterone group， and Shoutai Wan group， with 15 mice in each group. The mice in the normal group and model group were given 0.2 ml distilled water by gavage each day， the Shoutai Wan group given Shoutai Wan decoction 0.15 g/（10 g·d） by gavage， the progesterone group given progesterone tablets 0.44 mg/（10 g·d） by gavage. After gavage for 14 days， the mice were cohabited. Female CBA/J mice in the normal group were mated with male BALB/c mice at a ratio of 2∶1， and female CBA/J mice in the other groups were mated with male DBA/2 mice at a ratio of 2∶1 to establish the RSA mouse model. Vaginal smears were taken from the female mice the next morning， and the appearance of a large number of spermatozoa and the presence of a vaginal plug were considered as the first day of pregnancy. After the appearance of the plug， the mice were continued to be administered according to the previous method until the 10th day of pregnancy. On the 10th day of pregnancy， maternal-fetal interface tissues were collected from each group of mice， and lactate dehydrogenase colorimetric method was used to detect lactate （LA） content； qPCR method and Western blot method were used to detect the expression of immune-related factors interleukin-4 （IL-4）， interferon-gamma （IFN-γ）， transforming growth factor beta 1 （TGF-β1）， and forkhead box protein 3 （Foxp3） mRNA and protein； flow cytometry was used to detect the numbers of helper T lymphocyte 1 （Th1）， helper T lymphocyte 2 （Th2）， regulatory T cell （Treg）， classical macrophage （M1）， and alternative macrophage （M2）. The bivariate Pearson test was used to analyze the correlation between LA content and the numbers of Th1， Th2， Treg， M1， and M2 cells， as well as the correlation between LA content and the expression of IL-4， IFN-γ， TGF-β1， Foxp3 protein， and mRNA. ResultsOn the 10th day of pregnancy， compared with the normal group， the LA content decreased in the model group， and the expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues decreased， while the expression of IFN-γ protein and mRNA increased. The numbers of Th1 and M1 cells increased， while the numbers of Th2， Treg， and M2 cells decreased （P＜0.05 or P＜0.01）. Compared with the model group， the LA content increased in the Shoutai Wan group and progesterone group. The expression of IL-4， TGF-β1， Foxp3 protein and mRNA in the maternal-fetal interface tissues increased， while the expression of IFN-γ protein and mRNA decreased. The numbers of Th1 and M1 cells decreased， while the numbers of Th2， Treg， and M2 cells increased （P＜0.05 or P＜0.01）. The LA content was positively correlated with the numbers of Th2， Treg， and M2 cells， and the expression of IL-4， TGF-β1， Foxp3 protein， and mRNA （P＜0.05 or P＜0.01）； the LA content was negatively correlated with the numbers of Th1， M1 cells， and the expression of IFN-γ protein and mRNA （P＜0.05 or P＜0.01）. ConclusionShoutai Wan may improve immune tolerance by regulating the expression of immune-related factors in the acidic microenvironment at the maternal-fetal interface of RSA model mice， thereby exerting its role in preventing miscarriage.

Objective:To evaluate the practical value of ultrasound, ultrasound new technologies (ultrasound elastography, contrast enhanced ultrasound) and computed tomography (CT) examination alone or the combination of both of the four in the clinical diagnosis of lymph node metastasis of thyroid cancer by meta-analysis system.Methods:This study screened relevant literature on ultrasound, new ultrasound technologies, and CT in the diagnosis of lymph node metastasis of thyroid cancer by searching Chinese and English databases from January 2006 to August 2023. Two scholars independently assessed the quality of the literatures and scored them using the QUADAS scale. Then, the diagnostic ratio of single and combined examinations was analyzed by Meta-Disc software, and the heterogeneity test and meta-analysis were performed to calculate the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, diagnostic ratio, accuracy, and area under curve (AUC). Finally, the diagnostic efficacies of different diagnostic techniques and their combination in identifying lymph node metastasis of thyroid cancer were assessed by calculating OR and P values by two-by-two comparisons. Results:Sixty-nine diagnostic studies totaling 30, 666 lesions were finally included. The meta-analysis study showed that contrast enhanced ultrasound had the highest sensitivity[0.83(0.77-0.87)], ultrasound specificity was the highest [0.84(0.79-0.88)], the highest AUC was for contrast enhanced ultrasound (0.90), and contrast enhanced ultrasound and ultrasound elastography had high accuracies (0.81, 0.80, respectively) both of them were higher than those of ultrasound (0.77) and CT (0.69). Contrast enhanced ultrasound and ultrasound elastography were both more sensitive than CT, with statistically significant differences between them ( P<0.01); contrast enhanced ultrasound + ultrasound elastography had the highest accuracy, while ultrasound + contrast enhanced ultrasound and contrast enhanced ultrasound + ultrasound elastography were both more sensitive, with no statistically significant differences between them ( P>0.05), but the latter had the highest specificity [0.90(0.88-0.92)], which were statistically significantly different from each other ( P<0.05), ultrasound+ contrast enhanced ultrasound and contrast enhanced ultrasound+ ultrasound elastography had higher sensitivities than ultrasound+ CT, which were statistically different from each other ( P<0.05), and ultrasound+ CT had the lowest specificity [0.76(0.70-0.81)]. Conclusions:The diagnostic efficacy of thyroid cancer lymph node metastasis is highest with contrast enhanced ultrasound. The new ultrasound technique for diagnosing thyroid cancer lymph node metastasis has a higher diagnostic value than CT, and it can be used as a complementary examination to conventional ultrasound.When the two techniques are used in combination, contrast enhanced ultrasound + ultrasound elastography has the highest accuracy, contrast enhanced ultrasound + ultrasound elastography and ultrasound + contrast enhanced ultrasound both have high sensitivity and specificity, and the diagnostic performance of both is higher than that of ultrasound + ultrasound elastography and ultrasound + CT, and in actual clinical practice when ultrasound elastography combined with contrast enhanced ultrasound is limited in the examination, ultrasound combined with contrast enhanced ultrasound can effectively serve as an alternative means to provide a good diagnostic support.

Objective:To compare the differences in surgical safety and postoperative cosmetic effects between endoscopic nipple-sparing mastectomy with immediate prepectoral prosthesis breast reconstruction and conventional nipple-sparing mastectomy with immediate subpectoral prosthesis breast reconstruction.Methods:The clinical data of early breast cancer patients admitted to the Department of Breast Surgery of Peking University Peoples Hospital from Oct 1, 2022 to Sep 13, 2023 was retrospectively analyzed.Results:According to the surgical method, the patients were divided into endoscopic surgery group (30 cases) and traditional surgery group (46 cases). There were no significant differences in the basic clinicopathological data, and the number of sentinel lymph nodes taken and axillary lymph nodes dissected between the patients in two groups (all P>0.05). Compared with that in traditional surgery group, the patients in endoscopic surgery group had longer operation time and more wound drainage volumes 3 days after surgery (all P<0.05). There was no significant differences in the probability of postoperative complications between the patients in two groups (all P>0.05), however, the proportion of nipple-areola complex necrosis in patients of endoscopic surgery group (10.0%) was lower than that of traditional surgery group (26.1%). Conclusions:The single-port insufflation technique-assisted endoscopic nipple-sparing mastectomy with immediate prepectoral prosthesis breast reconstruction maximize the cosmetic effect. Under the premise of strict selection of indications, it can be an optional surgical method.

Purpose: This study aims to elucidate the longitudinal alterations in frailty and health-related quality of life experienced by elderly patients undergoing surgical treatment for esophageal cancer. Additionally, it seeks to ascertain the impact of preoperative frailty on postoperative health-related quality of life over time. Methods: 131 patients were included in the prospective study. Patients' frailty and health-related quality-of-life were assessed utilizing the Tilburg and European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 at preoperative, 1 week, 1 month, and 3 months, postoperatively. Statistical analyses were performed using generalized estimating equations, repeated-measures analysis of variance, and linear mixed models (LMMs). Results: Out of 131 patients, 28.2% had frailty before surgery, and the prevalence of frailty consistently higher after surgery compared with baseline (67.9%, 51.9%, and 39.7%). There was no significant change in frailty scores in preoperative frail patients within 3 months following surgery (p = .496, p < .999, p < .999); whereas in preoperative non-frail patients, the frailty scores increased at 1 week (p < .001) and then decreased at 1 month (p = .014), followed by no change at 3 months. In addition, preoperative frail patients had significantly worse global quality-of-life (β = −4.24 (−8.31; −.18), p = .041), physical functioning (β = −9.87 (−14.59; −5.16), p < .001), role functioning (β = −10.04 (−15.76; −4.33), p = .001), and social functioning (β = −8.58 (−15.49; −1.68), p = .015), compared with non-frail patients. Conclusions A significant proportion of participants exhibited a high prevalence of preoperative frailty. These patients, who were preoperatively frail, exhibited a marked reduction in health-related quality-of-life, a more gradual recovery across various functional domains, and an increased symptom burden during the follow-up period. Therefore, it is crucial to meticulously identify and closely monitor patients with preoperative frailty for any changes in their postoperative physiology, role, and social functioning.

Objective:To explore the clinical application value of general coagulation indices and neutrophil-to-lymphocyte ratio (NLR) for assessing coagulation status of patients with ovarian cancer.Methods:The data of 190 patients with ovarian cancer who were admitted to the Second Hospital of Shanxi Medical University from October 2019 to September 2022 were retrospectively analyzed. According to the International Federation of Gynecology and Obstetrics (FIGO) staging, the patients were divided into early (stage Ⅰ-Ⅱ) ovarian cancer group (70 cases) and advanced (stage Ⅲ-Ⅳ) ovarian cancer group (120 cases). Forty-four patients with benign ovarian tumors who were treated in the Second Hospital of Shanxi Medical University during the same period were selected. Plasma D-dimer (D-D), activated partial thromboplastin time (APTT), prothrombin time (PT), fibrinogen (FIB) and thrombin time (TT) were tested. Platelet count (Plt), neutrophil count and lymphocyte count were measured by blood cell analyzer, and NLR was calculated. The receiver operating characteristic (ROC) curve was used to analyze the value of coagulation indices and NLR in the assessment of venous thromboembolism (VTE) in patients with ovarian cancer.Results:Compared with the benign ovarian tumor group, PT of patients in the early and advanced ovarian cancer groups was shorter (both P < 0.05), and D-D and Plt increased (both P < 0.05). Compared with the benign ovarian tumors group, TT of patients in the advanced ovarian cancer group decreased ( P < 0.05), and FIB and NLR increased (both P < 0.05). Compared with the early ovarian cancer group, PT and TT in the advanced ovarian cancer group were shorter (both P < 0.05), and FIB, D-D, NLR and Plt increased (all P < 0.05). The optimal cut-off values of FIB, D-D and NLR in stage Ⅰ-Ⅱ and stage Ⅲ-Ⅳ patients with VTE in ovarian cancer group were 3.165, 333.500 and 2.455, and the area under the curve (AUC) was 0.731, 0.837 and 0.759. Conclusions:The coagulation indices of patients with ovarian cancer are abnormal during treatment, suggesting that patients may produce active thrombosis, and the symptoms of patients in advanced stage are more serious.
