Coptis chinensis Franch. and Panax ginseng C. A. Mey. are traditional herbal medicines with millennia of documented use and broad therapeutic applications, including anti-diabetic properties. However, the synergistic effect of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng on type 2 diabetes mellitus (T2DM) and its underlying mechanism remain unclear. The research demonstrated that the optimal ratio of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng was 4∶1, exhibiting maximal efficacy in improving insulin resistance and gluconeogenesis in primary mouse hepatocytes. This combination demonstrated significant synergistic effects in improving glucose tolerance, reducing fasting blood glucose (FBG), the weight ratio of epididymal white adipose tissue (eWAT), and the homeostasis model assessment of insulin resistance (HOMA-IR) in leptin receptor-deficient (db/db) mice. Subsequently, a T2DM liver-specific network was constructed based on RNA sequencing (RNA-seq) experiments and public databases by integrating transcriptional properties of disease-associated proteins and protein-protein interactions (PPIs). The network recovery index (NRI) score of the combined treatment group with a 4∶1 ratio exceeded that of groups treated with individual components. The research identified that activated adenosine 5'-monophosphate-activated protein kinase (AMPK)/acetyl-CoA carboxylase (ACC) signaling in the liver played a crucial role in the synergistic treatment of T2DM, as verified by western blot experiment in db/db mice. These findings demonstrate that the 4∶1 combination of total alkaloids from Coptis chinensis and total ginsenosides from Panax ginseng significantly improves insulin resistance and glucose and lipid metabolism disorders in db/db mice, surpassing the efficacy of individual treatments. The synergistic mechanism correlates with enhanced AMPK/ACC signaling pathway activity.

Objective To investigate the health education needs and available resources in schistosomiasis-endemic areas based on integration of community resources, and to explore the operation pathways for health education and promotion during the stage of schistosomiasis elimination. Methods A community was selected from Nanji Township, Xinjian District, Nanchang City, Jiangxi Province around the Poyang Lake areas as the study site, and a questionnaire survey on health education needs for schistosomiasis control was conducted among permanent residents at ages of 20 years in the community during the period between June and July, 2022 using face-to-face interviews. In addition, the resources available for the community-based schistosomiasis control health education were investigated among workers in township-level specialized institutions, members of civil society organizations, villagers, teachers and high and primary school students through field observations, field surveys and thematic interviews. Results A total of 304 individuals participated in the questionnaire survey on community-based health education needs for schistosomiasis control, and 94.41% (287/304) and 93.42% (284/304) of the respondents were most interested in knowing/understanding knowledge of the morphology of schistosomes and knowledge associated with the transmission route of schistosomiasis. The four most popular patterns for disseminating schistosomiasis control knowledge included live broadcasting of schistosomiasis control videos (94.41%, 287/304), printed brochures (89.80%, 273/304), special lectures by doctors (62.50%, 190/304) and physical health education materials for schistosomiasis control (61.51%, 187/304). There were 96.71% (294/304) and 77.63% (236/304) of respondents that accepted the participation of township healthcare center and township government/village committees in dissemination of schistosomiasis control knowledge, and there were 95.72% (291/304) and 80.59% (245/304) of respondents that mainly acquired schistosomiasis control knowledge through village allocation of leaflets and volunteer schistosomiasis control activities, respectively. There was 96.71% (294/304) of respondents participating in the dissemination activities of schistosomiasis control knowledge held by village committees, township healthcare centers, and high and primary schools/kinder-gartens, and 61.25% (177/289) of respondents were willing to participate in volunteer schistosomiasis control activities. A total of 115 individuals participated in the survey of available resources for community-based schistosomiasis control health education, and there were a large number of organizational, human and cultural resources in the community that were useful for health communication services. Conclusions The abundant human and material resources from rural communities in schistosomiasis-endemic areas may be integrated into schistosomiasis control health education to generate a rural health education pathway with the joint participation of schistosomiasis control institutions, township governments, community departments and community residents, which may provide insights into the future development of schistosomiasis control health education.

Objective:To investigate the effect of anoxic cold environment at 4500 m altitude on female men-struation.Methods:From March 1 to March 20,2023,women in a unit at an altitude of 4500 meters were selected for reproductive health questionnaire survey,and were divided into≤6 months group,6 months to 12 months group and≥12 months group according to altitude exposure time.The changes of menstruation in each group were analyzed to explore the relevant influencing factors.Results:The total incidence of abnormal menstruation in working women in hypoxic cold environment was as high as 66.14%,and there was no statistically significant difference between the groups at different high-altitude exposure times(P＞0.05).The highest incidence of dys-menorrhea among the types of menstrual changes was 61.90%,but there was no statistically significant differ-ence between the groups at different high altitude exposure times(P＞0.05).There was a statistically significant difference(P＜0.05)in the proportion of insufficient sleep for at least 3 days per week,nervousness and anxiety,and training during their menstrual period in the women who experienced changes in their menstrual cycle com-pared to those who did not.Conclusions:Hypoxic cold environment can lead to the change of female menstrua-tion,and it is combined with sleep deficiency,tension and anxiety,and menstrual exercise.

Objective:To evaluate the correlation and consistency between quantitative coronary flow fraction (QFR) and cardiac magnetic resonance imaging (CMR) in assessing myocardial ischemia in patients with coronary heart disease (CAD).Methods:A retrospective analysis was conducted on the data of coronary heart disease patients who underwent load CMR examination and coronary angiography at the Beijing Anzhen Hospital, Capital Medical University from August 2017 to March 2022. CMR examination includes cardiac cine, load/rest myocardial perfusion imaging, and delayed enhancement sequence. According to the results of CMR examination, the patient′s left ventricular myocardial segments were divided into normal segment group and abnormal segment group (further divided into ischemic segment group and infarcted segment group). On the basis of coronary angiography, an artificial intelligence based platform (AngioPlus system) was applied to calculate the preoperative coronary artery QFR value of patients undergoing percutaneous coronary intervention treatment. Kappa test was used to evaluate the consistency of QFR and CMR in diagnosing abnormal myocardium; Mann Whitney U test was used to compare the differences in QFR between groups; The receiver operating characteristic (ROC) curve was used to evaluate the efficacy of QFR in diagnosing abnormal myocardium; Spearman correlation analysis was used to clarify the relationship between myocardial infarction area and QFR value of the supplying coronary artery in patients.Results:Among the 70 CAD patients enrolled, there were 60 males and 10 females, aged (54.1±11.1)years. At the vascular level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) is moderate (Kappa value=0.514). The sensitivity and specificity of detecting abnormal myocardial segments in CAD patients were 57% and 91%, respectively. The area under the curve (AUC) value of QFR predicting abnormal myocardium in CAD patients was 0.769, and the optimal cutoff value was QFR=0.865. At this time, the sensitivity and specificity of QFR predicting myocardial injury in CAD patients were 67.2% and 84.3%, respectively. The difference in vascular QFR between the normal segment group, ischemic segment group, and infarcted segment group was statistically significant ( P<0.001), with the infarcted segment group having significantly lower QFR values than the other two groups (all P<0.01). The range of myocardial infarction was negatively correlated with the QFR value of the supplying coronary artery ( r=-0.45, P<0.001). At the patient level, the consistency between QFR and CMR in diagnosing myocardial injury (including ischemia and infarction) was moderate (Kappa value=0.445), with a sensitivity of 74% and a specificity of 81% for diagnosing myocardial injury in CAD patients. Conclusions:Compared with CMR, QFR has better specificity in detecting myocardial injury in CAD patients. The QFR value of the infarcted segment group is significantly lower than that of the ischemic group and the normal group. The area of myocardial infarction is negatively correlated with the QFR value of the supplying coronary artery.

The professional identification score of oncology nurses was (108.96 ± 20.29) points, the empathy fatigue score was (81.30 ± 9.00) points, and the death coping ability score was (112.39 ± 23.52) points.Pearson correlation analysis showed that compassion fatigue was negatively correlated with professional identification and death coping ability( r = - 0.428, - 0.326, both P<0.01), while occupational identity was positively correlated with death coping ability ( r = 0.565, P<0.01). Professional identification played a partial mediating role between compassion fatigue and death coping ability of nurses in the oncology department, and the mediating effect was - 0.34, accounting for 52.3% of the total effect. Conclusions:In this study, the professional identification score of nurses in the oncology department was at a moderate level, the compassion fatigue score was at the moderate to severe level, and the death coping ability score was at a moderate level. Professional identification is an important mediating variable between compassion fatigue and death coping ability of nurses in the oncology department that improve their professional identification, reduce their compassion fatigue and improve their death coping ability.

In the past decades, significant progress has been achived in cartilage regeneration. The traditional techniques for constructing tissue engineering cartilage scaffold mainly include pore agent method (or template method), phase separation method, gas foaming method, freeze-drying method, electrospinning method, etc. Cartilage is heterogeneous, and it is difficult for traditional scaffolds to simulate the high anisotropy of cartilage. Therefore, functional regeneration of cartilage is challenging. With the progress of three-dimensional(3D) printing technology, it is possible to prepare functional bionic scaffolds with fine structure and gradient changes through co-deposition of biomaterials, cells and active biomolecules, so as to achieve functional cartilage regeneration. This article reviewed 3D printing technology of cartilage tissue engineering, and the application of 3D printing technology in cartilage regeneration at different anatomical positions (articular cartilage, auricle cartilage, nasal cartilage). In addition, the importance of preparing bionic constructs with regional structure gradient and regional composition gradient was discussed. 3D bioprinting technology, 4D printing techniques, smart biomaterials brought hope for the construction of bionic tissues and organs.

Objective:To analyze the clinical and genetic characteristics of a child featuring Dias-Logan syndrome.Methods:A child with speech disorders and delayed psychomotor development from childhood who was admitted to the Rehabilitation Medicine Department of Children′s Hospital Affiliated to Zhengzhou University in July 2022 was selected as the research subject. Clinical data of the child was collected. Genomic DNA was extracted from peripheral blood samples of the child and his parents. Potential variant was screened by whole exome sequencing, and candidate variant was verified by Sanger sequencing. This study was approved by the Children′s Hospital Affiliated to Zhengzhou University (Ethics No. 2023-K-011).Results:The child has presented with global developmental delay, microcephaly, special facial features and behavioral problems. Genetic testing revealed a de novo variant of the BCL11A gene, namely c. 561_567delACACGCA(p.Q187fs*7), which was classified as pathogenic (PVS1+ PS2+ PM2_Supporting).
