Hyssopus cuspidatus is an authentic medicinal herb used in Xinjiang， rich in the chemical constituents including flavonoids， phenolic acids and terpenoids. It possesses anti-inflammatory， antioxidant， and immunomodulatory effects. Modern pharmacological studies have demonstrated that H. cuspidatus exerts therapeutic effects on asthma by inhibiting airway inflammatory responses， suppressing airway remodeling， modulating the function of the hypothalamic-pituitary-adrenal axis， and relaxing bronchial smooth muscle. It also demonstrates intervention effects on chronic obstructive pulmonary disease by reducing levels of inflammatory cytokines and regulating immune balance. Additionally， H. cuspidatus can mitigate acute lung injury by inhibiting oxidative stress and intervene in lung cancer by suppressing proliferation and promoting apoptosis of lung cancer cells. In terms of clinical application， compound preparations containing H. cuspidatus， such as Hanchuan zupa granules and Luo’ou kezupa， have demonstrated favorable therapeutic effects on pulmonary diseases including asthma， cough， and pediatric bronchopneumonia. Currently， the research on precise action targets and compound matching rules of H. cuspidatus remains inadequate. Future studies should integrate modern technologies such as metabolomics to conduct in-depth exploration， thereby promoting the modernized development and clinical application of this traditional medicinal herb.

Objective:To analyze the distribution and drug resistance of pathogens of bacterial bloodstream infection in patients with hematological diseases in the Department of Hematology of Tianjin Medical University General Hospital, and to provide etiological data for clinical empirical anti-infection treatment.Methods:A retrospective analysis was conducted on the general clinical information, pathogenic bacteria and drug susceptibility test results of patients with hematological diseases diagnosed with bacterial bloodstream infection by menstrual blood culture in our center from January 2016 to December 2022.Results:Patients included 498 inpatients, with a total of 639 bacterial strains. Among the patients, 86.9% patients had malignancies, and 76.7% had agranulocytosis. Symptoms of concurrent infections, including those of the respiratory tract, oral mucosa, skin and soft tissues, and abdominal sources were observed in 68.3% patients. Gram-negative bacteria (G -) accounted for 79.0% of the isolated bacteria, and gram-positive bacteria (G +) accounted for 21.0%. The top five isolated pathogens were Klebsiella pneumoniae (22.5%), Escherichia coli (20.8%), Pseudomonas aeruginosa (15.0%), Enterococcus faecium (5.5%), and Stenotrophomonas maltophilum (5.0%). Escherichia coli exhibited a decreasing trend of resistance to quinolones, cephalosporins, and carbapenems. Klebsiella pneumoniae exhibited increasing rates of resistance to quinolones and cephalosporins between 2016 and 2018, but the rated decreased after 2019. The resistance rate to carbapenems exhibited by Pseudomonas aeruginosa was approximately 20%. Carbapenem-resistant strains of Pseudomonas aeruginosa strains were first detected in 2017, with a peak resistance rate of 35.7%, detected in 2019. A 60.0% resistance rate to methicillin was observed in methicillin-resistant coagulase-negative staphylococci (MRCNS), and one case of linezolid-resistant MRCNS was detected. Conclusions:Pathogenic bacteria of bacterial bloodstream infections were widely distributed in our center, and precautions are warranted against carbapenem resistant P. aeruginosa and Klebsiella pneumoniae.

Scavenger receptor class B, member 2 (SCARB2) is linked to Gaucher disease and Parkinson's disease. Deficiency in the SCARB2 gene causes progressive myoclonus epilepsy (PME), a rare group of inherited neurodegenerative diseases characterized by myoclonus. We found that Scarb2 deficiency in mice leads to age-dependent dietary lipid malabsorption, accompanied with vitamin E deficiency. Our investigation revealed that Scarb2 deficiency is associated with gut dysbiosis and an altered bile acid pool, leading to hyperactivation of FXR in intestine. Hyperactivation of FXR impairs epithelium renewal and lipid absorption. Patients with SCARB2 mutations have a severe reduction in their vitamin E levels and cannot absorb dietary vitamin E. Finally, inhibiting FXR or supplementing vitamin E ameliorates the neuromotor impairment and neuropathy in Scarb2 knockout mice. These data indicate that gastrointestinal dysfunction is associated with SCARB2 deficiency-related neurodegeneration, and SCARB2-associated neurodegeneration can be improved by addressing the nutrition deficits and gastrointestinal issues.

Objective:To explore the teaching effect and novel ideas of online teaching applied in skill operation course.Methods:One hundred and fifty-one students studying in Sichuan University taking the First Aid in the Life: Basic Knowledge and Skills as an elective course in the autumn semester of 2019 and spring semester of 2020 were included as the research subjects in this study. Among them, 77 students in the spring semester of 2020 were selected as the experimental group and 74 students in the autumn semester of 2019 were selected as the control group. The students in the experimental group studied the first aid course by online platform, and the others in the control group studied through traditional teaching mode. The teaching effect of the two groups was compared and the teaching satisfaction of the two groups weas analyzed. SPSS 23.0 was used for Chi-square test and t-test. Results:There was no significant difference between the control group and the experimental group in the assessment scores of cardiopulmonary resuscitation, hemostatic bandaging, and fracture fixation [(8.65±0.81 vs 8.69±0.90, P=0.750); (8.10±0.50 vs 8.12±0.61, P=0.880); (8.21±0.89 vs 8.16±0.78, P=0.710)]. Among the students participating in the questionnaire survey in the experimental group, 59 (95.16%) students thought that this course was helpful in dealing with first aid in daily life, and 38 (61.29%) students did not want to change the traditional teaching method to online teaching. Conclusion:The application of online teaching in first-aid skill operation course is feasible and can achieve the similar teaching effect, which provides a novel idea for exploring the online teaching of first aid skills.

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.

Malaria remains one of the most serious public health problems in tropical and subtropical countries and regions. In the control of the vector Anopheles, insecticide-treated bed nets and indoor residual spraying, which have been promoted to interrupt malaria transmission by only preventing indoor blood-sucking by adult mosquitoes, consequently have been widely used in malaria-endemic areas. However, the efficacy of these measures in interrupting malaria transmission is gradually decreasing due to the development of mosquito resistance. In contrast, Anopheles larval source management can effectively reduce the population density of indoor and outdoor blood-sucking, wild and domestic mosquitoes. It can also be combined with adult mosquito control to become an important adjunct to existing adult mosquito control measures. In more than 70 years of malaria control and elimination in China, according to different conditions in different places, exploration and practice have been carried out in different types of control of malaria Anopheles larvae, such as habitat modification, habitat manipulation, larviciding, and biological control. These efforts have accumulated rich experience and resulted in strategies tailored to local conditions, integrated control, community involvement, and methodological innovation. This paper outlines the main practices and basic strategies of Anopheles larval source management for malaria control in China, with the aim of providing references for malaria control in other regions where malaria is still endemic.

The finite element method is a new method to study the mechanism of brain injury caused by blunt instruments. But it is not easy to be applied because of its technology barrier of time-consuming and strong professionalism. In this study, a rapid and quantitative evaluation method was investigated to analyze the craniocerebral injury induced by blunt sticks based on convolutional neural network and finite element method. The velocity curve of stick struck and the maximum principal strain of brain tissue (cerebrum, corpus callosum, cerebellum and brainstem) from the finite element simulation were used as the input and output parameters of the convolutional neural network The convolutional neural network was trained and optimized by using the 10-fold cross-validation method. The Mean Absolute Error (MAE), Mean Square Error (MSE), and Goodness of Fit ( R ²) of the finally selected convolutional neural network model for the prediction of the maximum principal strain of the cerebrum were 0.084, 0.014, and 0.92, respectively. The predicted results of the maximum principal strain of the corpus callosum were 0.062, 0.007, 0.90, respectively. The predicted results of the maximum principal strain of the cerebellum and brainstem were 0.075, 0.011, and 0.94, respectively. These results show that the research and development of the deep convolutional neural network can quickly and accurately assess the local brain injury caused by the sticks blow, and have important application value for understanding the quantitative evaluation and the brain injury caused by the sticks struck. At the same time, this technology improves the computational efficiency and can provide a basis reference for transforming the current acceleration-based brain injury research into a focus on local brain injury research.
