Glucose-6-phosphate dehydrogenase (G6PD) is the first rate-limiting enzyme of the pentose phosphate pathway, which regulates the production of nicotinamide adenine dinucleotide phosphate (NADPH) in cells, and plays an important role in redox reactions. In addition, NADPH is necessary for biosynthesis reactions and is an essential hydrogen donor in the biosynthesis of cholesterol, fatty acids, and sex hormones. NADPH also plays an important role in maintaining intracellular redox homeostasis, converting intracellular oxidized glutathione into reduced glutathione (GSH), which is the main intracellular antioxidant. Therefore, G6PD plays an important role in maintaining intracellular redox homeostasis. Studies have shown that the decrease in G6PD activity can lead to a breakdown of the redox balance in the cells and tends to the oxidation state, which not only leads to dysregulation of cell growth and signaling, but also makes the host more susceptible to viruses. Previous studies have focused on the molecular characteristics of G6PD, anemia caused by G6PD deficiency, and the relationship between malignant tumors and G6PD. In recent years, more attentions have been paid to the importance of G6PD at the cellular level, development, and disease progression. To explore the effects of G6PD on viral life cycle, the relationship between G6PD and viral infections, including the clinical symptoms and virus-host interactions of hepatitis B virus (HBV), human papilloma virus (HPV), hepatitis E virus (HEV), influenza virus and dengue fever virus (DENV) will be reviewed, which will benefit the antiviral drugs development. Many studies had proved that patients with deficient G6PD are more susceptible to HBV infection. It has been reported that HBV infection activates the glycolytic pathway, promotes pentose phosphate pathway, and accelerates citric acid cycle to enhance nucleotide and fat biosynthesis, thereby promoting viral replication. During HPV infection, miR-206 up-regulates the expression of G6PD to facilitate viral replication. Thus, G6PD may be a new target for anti-cervical cancer therapy. It was reported that patients with G6PD deficiency are more susceptible to HEV infection, and more serious HEV infection-associated diseases are developed. However, the mechanism of why and how the deficiency of G6PD affect HEV infection is still unclear. The oxidative stress caused by G6PD deficiency provides a suitable environment for influenza virus replication. Furthermore, patients with G6PD deficiency are more susceptible to SARS-CoV-2 infection and lead to more severe clinical symptoms with a higher risk of thrombosis and hemolysis than general population. There is a correlation between DENV infection and G6PD deficiency, which increase the risk of hemolysis, however, the pathogenesis is still unknown. The deficiency of G6PD promotes HCoV 229E infection, possibly because the NF-κB signal pathway is suppressed when G6PD deficiency, which results in decreased innate antiviral immune, and increased susceptibility to HCoV 229E, finally leads to increased viral replication. Thus, the deficiency of G6PD play an important role during viruses’ infection, especially the susceptibility. More studies should be performed on the relicationship between G6PD deficiency and specific viral susceptibility, and more attentions shoud be paid to G6PD deficient patients, which will benefit the treatment of viral infection and the development of antiviral drugs.

Objective:To study the effects of applying the think-pair-share (TPS) method combined with the microlecture teaching model in nursing teaching of general surgery.Methods:We assigned 48 nursing students interning in the department of general surgery of The First Affiliated Hospital of Air Force Medical University from August 2020 to August 2021 into control group to receive traditional teaching and 48 nursing students who interned from September 2021 to August 2022 into observation group to receive TPS+microlecture teaching. The two groups were compared in terms of test results, critical thinking abilities, post competencies, and satisfaction with teaching. SPSS 22.0 was used to perform the t test and chi-square test. Results:The observation group showed a significantly higher theoretical score [(93.21±4.34) vs. (88.65±3.69)], a significantly higher basic nursing skills score [(94.21±3.85) vs. (89.45±5.47)], and a significantly higher specialized skills score [(90.76±4.59) vs. (88.96±3.63)] than the control group ( P<0.05). The total score of the critical thinking ability scale and the scores of individual dimensions were significantly increased after training for both groups, and all the scores were significantly higher in the observation group than in the control group ( P<0.05). Both groups had significant improvements in the total and individual scores of post competencies after training, and the observation group had significantly higher scores than the control group ( P<0.05). Compared with the control group, the observation group had significantly higher proportions of students feeling satisfied with teaching, in terms of all evaluation items and also overall ( P<0.05). Conclusions:Applying the TPS+microlecture teaching model in general surgery nursing teaching can help nursing students improve theoretical and practical levels, critical thinking abilities, and post competencies, also with a high level of satisfaction with teaching.

Severe cerebrovascular disease is a kind of severe cerebrovascular disease involving disturbance of consciousness,which corresponds to the viscera of stroke in traditional Chinese medicine(TCM).Rooted in the TCM classics such as Huang Di Nei Jing(The Yellow Emperor's Inner Classic)and Shang Han Lun(Treatise on Cold Damage),Professor WU Hai-Ke studied the TCM pathogenesis theory recorded in the chapter of Profound and Important Theory in Plain Questions(Su Wen)carefully.Based on its clinical practice and inherited the traditional four diagnostic methods of inspection,auscultation-olfaction,interrogation,and palpation,Professor WU Hai-Ke simplified and created the six-differentiation method for the syndrome differentiation of patients with severe cerebrovascular disease:distinguishing the mind to learn the progression of the disease,distinguishing the complexion to know the exuberance or decline of qi and blood,distinguishing the tongue picture to predict the aggravation or relief of the disease,distinguishing the pulse condition to judge the prognosis,distinguishing the breath to know the deficiency or excess of zang-fu organs,and distinguishing cold-heat to identify the exterior,interior,yin and yang.The six-differentiation method highlights the significance of mind,complexion,tongue picture,pulse condition,breath,and cold-heat in the syndrome differentiation of patients with severe cerebrovascular disease.The clinical information of six-differentiation method is easy to obtain,and the method presents the characteristics and advantages of TCM diagnostic methods in the syndrome differentiation of patients with severe cerebrovascular disease,which will provide reference for the establishment of clinical diagnosis and treatment norms of TCM for severe cerebrovascular disease.

Objective To monitor the susceptibility of clinical isolates to antimicrobial agents in tertiary hospitals in major regions of China in 2022.Methods Clinical isolates from 58 hospitals in China were tested for antimicrobial susceptibility using a unified protocol based on disc diffusion method or automated testing systems.Results were interpreted using the 2022 Clinical &Laboratory Standards Institute(CLSI)breakpoints.Results A total of 318 013 clinical isolates were collected from January 1,2022 to December 31,2022,of which 29.5％were gram-positive and 70.5％were gram-negative.The prevalence of methicillin-resistant strains in Staphylococcus aureus,Staphylococcus epidermidis and other coagulase-negative Staphylococcus species(excluding Staphylococcus pseudintermedius and Staphylococcus schleiferi)was 28.3％,76.7％and 77.9％,respectively.Overall,94.0％of MRSA strains were susceptible to trimethoprim-sulfamethoxazole and 90.8％of MRSE strains were susceptible to rifampicin.No vancomycin-resistant strains were found.Enterococcus faecalis showed significantly lower resistance rates to most antimicrobial agents tested than Enterococcus faecium.A few vancomycin-resistant strains were identified in both E.faecalis and E.faecium.The prevalence of penicillin-susceptible Streptococcus pneumoniae was 94.2％in the isolates from children and 95.7％in the isolates from adults.The resistance rate to carbapenems was lower than 13.1％in most Enterobacterales species except for Klebsiella,21.7％-23.1％of which were resistant to carbapenems.Most Enterobacterales isolates were highly susceptible to tigecycline,colistin and polymyxin B,with resistance rates ranging from 0.1％to 13.3％.The prevalence of meropenem-resistant strains decreased from 23.5％in 2019 to 18.0％in 2022 in Pseudomonas aeruginosa,and decreased from 79.0％in 2019 to 72.5％in 2022 in Acinetobacter baumannii.Conclusions The resistance of clinical isolates to the commonly used antimicrobial agents is still increasing in tertiary hospitals.However,the prevalence of important carbapenem-resistant organisms such as carbapenem-resistant K.pneumoniae,P.aeruginosa,and A.baumannii showed a downward trend in recent years.This finding suggests that the strategy of combining antimicrobial resistance surveillance with multidisciplinary concerted action works well in curbing the spread of resistant bacteria.

italic>Astragalus is a commonly used Chinese medicinal material in traditional Chinese medicine (TCM), and with the increase of planting area in recent years, the damage of Astragalus root rot has worsened year by year, which seriously affecting its quality and yield. Fusarium oxysporum is one of the main pathogens causing root rot in astragalus. In this study, UPLC-Q-TOF-MS based metabolomic approach combined with multivariate statistical analysis were used to analyze the metabolite changes of Astragalus in response to F. oxysporum infection. The results showed that 62 metabolites in the Astragalus had significant changes after inoculation of F. oxysporum. Polar metabolites included 40 flavonoids, 8 saponins, 2 nucleosides, 1 vitamin, 1 organic acid, 1 amino acid; while lipid metabolites included 3 fatty acids, 1 diradylglycerols, 2 lysophosphatidylcholine, 1 lysophosphatidylglycerol, 1 phosphatidylinositol, 1 sterol lipid. Among these differential metabolites, the relative content of flavonoids, vitamin B₂, tryptophan and salicylic acid were increased, while the relative content of saponins were decreased. Correlation analysis showed that the flavonoids were positively correlated with each other, and positively correlated with most lipids, but negatively correlated with most saponins. In addition, studies have shown that F. oxysporum infection is not an influencing factor for the generation of malonyl substitution of flavonoid. This study elucidates the effect of F. oxysporum infection on Astragalus from the perspective of plant metabolism, which provides a basis for exploring the interaction mechanism between the Astragalus and F. oxysporum and further promoting molecular breeding.

Objective: To study the incidence of bloodstream infections, pathogen distribution, and antibiotic resistance profile in patients with hematological malignancies. Methods: From January 2018 to December 2021, we retrospectively analyzed the clinical characteristics, pathogen distribution, and antibiotic resistance profiles of patients with malignant hematological diseases and bloodstream infections in the Department of Hematology, Nanfang Hospital, Southern Medical University. Results: A total of 582 incidences of bloodstream infections occurred in 22,717 inpatients. From 2018 to 2021, the incidence rates of bloodstream infections were 2.79%, 2.99%, 2.79%, and 2.02%, respectively. Five hundred ninety-nine types of bacteria were recovered from blood cultures, with 487 (81.3%) gram-negative bacteria, such as Klebsiella pneumonia, Escherichia coli, and Pseudomonas aeruginosa. Eighty-one (13.5%) were gram-positive bacteria, primarily Staphylococcus aureus, Staphylococcus epidermidis, and Enterococcus faecium, whereas the remaining 31 (5.2%) were fungi. Enterobacteriaceae resistance to carbapenems, piperacillin/tazobactam, cefoperazone sodium/sulbactam, and tigecycline were 11.0%, 15.3%, 15.4%, and 3.3%, with a descending trend year on year. Non-fermenters tolerated piperacillin/tazobactam, cefoperazone sodium/sulbactam, and quinolones at 29.6%, 13.3%, and 21.7%, respectively. However, only two gram-positive bacteria isolates were shown to be resistant to glycopeptide antibiotics. Conclusions: Bloodstream pathogens in hematological malignancies were broadly dispersed, most of which were gram-negative bacteria. Antibiotic resistance rates vary greatly between species. Our research serves as a valuable resource for the selection of empirical antibiotics.

Glucocorticoid-induced osteoporosis (GIOP) is a skeletal disease characterized by decreased bone strength and increased fracture risk associated with long-term glucocorticoid use. GIOP is the most common secondary osteoporosis that critically affects the quality of life of patients. Currently, the incidence of GIOP in China remains high, with insufficient awareness and lack of prevention and treatment norms. Therefore, the Chinese Rheumatology Association has established this standard based on domestic and international experience, with the aim of raising awareness of prevention and treatment among clinicians, guiding the standardized diagnosis and treatment of this disease, and improving the overall prognosis of patients with GIOP.

OBJECTIVE: To analyze factors associated with intestinal acute graft-versus-host disease (aGVHD) after allogeneic hematopoietic stem cell transplantation(allo-HSCT) in children and to develop a prediction model for intestinal aGVHD after allo-HSCT in children. METHODS: The clinical data of 62 children who underwent allo-HSCT at the Department of Hematology of the People's Hospital of Xinjiang Uygur Autonomous Region from February 2018 to September 2021 were retrospectively analyzed. Intestinal aGVHD was evaluated according to the Mount Sinai Acute GVHD International Consortium (MAGIC) grading criteria, the variables were screened by LASSO (least absolute shrinkage and selection operator) regression analysis with 10-fold cross-validation, and developed a model for predicting intestinal aGVHD after allo-HSCT in children. RESULTS: A total of 33 (53.2%) of the 62 children developed intestinal aGVHD, of which 25 were degree II and 8 were degree III-IV. The results of screening variables by 10-fold cross-validated LASSO regression showed that the significant variables included ethnic minorities (OR =7.229; 95%CI: 2.337-22.354), platelet (PLT) (OR =0.971; 95%CI: 0.932-0.993), uric acid (UA) (OR =0.971; 95%CI: 0.935-0.988), C-reactive protein (CRP) (OR =1.217; 95%CI: 1.053-1.545), and viral infection (OR =10; 95%CI: 3.021-32.668), and these variables were independently associated with intestinal aGVHD in children (all P <0.05). A prediction model was constructed based on above variables. The area under the receiver operating characteristic (ROC) curve (AUC) of the model was calculated, and the AUC value was 0.985 (0.966-1), the Brier score was 0.055. The evaluation showed that the model has a high degree of discrimination and calibration. CONCLUSION Ethnic minorities, low PLT, low UA, high CRP, and viral infections are independently associated with intestinal aGVHD in children, and early attention should be paid to these high-risk children.
