Diabetes mellitus （DM） is a metabolic disease caused by absolute or relative insulin deficiency and reduced insulin sensitivity in peripheral cells， posing a serious threat to global health. Chronic complications arising in the later stages of DM can lead to the decline or even loss of function in multiple organs， including the eyes， heart， liver， kidneys， nerves， and feet， making them the primary cause of mortality in DM patients. Although modern medicine has made some progress in the treatment of these complications， challenges such as high costs and adverse drug reactions remain. Thus， identifying highly effective drugs with minimal adverse effects has become a top priority. Astragalus membranaceus is a shining gem in the treasure trove of Chinese medicine. Numerous studies have shown that its primary active component， astragaloside Ⅳ， possesses various biological activities， including anti-inflammatory， antioxidant， and antiviral effects， as well as benefits for cardiac and cerebral function， nerve conduction， and myocardial protection. Meanwhile， the phosphatidylinositol 3-kinase/protein kinase B （PI3K/Akt） signaling pathway plays a crucial role in regulating oxidative stress， inflammatory responses， apoptosis， and autophagy. Extensive research has highlighted the significant role of this pathway in various DM complications， leading to widespread studies on its interaction with astragaloside Ⅳ. This review summarizes research findings on how astragaloside Ⅳ alleviates pancreatic cytotoxicity in DM patients by modulating the PI3K/Akt pathway. Additionally， it highlights its protective effects on basic cardiac function， inhibition of retinal cell damage， improvement of cerebral nerve dysfunction， reduction of chronic kidney and liver damage， and mitigation of neurovascular toxicity in the lower limbs. These insights provide a valuable reference for the clinical application of A. membranaceus and its active monomer， astragaloside Ⅳ， in the treatment of DM and its complications.

Objective To explore the medication rules and mechanism of Xin'an physicians in the treatment of diabetes mellitus.Methods The prescriptions for the treatment of diabetes mellitus in Xin'an medical writings were collected.The core drug prescriptions were obtained by using IBM SPSS Modeler 18.0 for dispensing association rules as well as complex network analysis,and the cluster analysis of high-frequency traditional Chinese medicines was carried out by using IBM SPSS Statistics 25.0.The active ingredients and targets of the core drugs were extracted from the BATMAN-TCM database.The GeneCards database was used to search for diabetes gene targets,and after obtaining the intersecting targets,the STRING online platform was imported to construct the protein interactions network,and screened the core genes by using the Cytoscape 3.9.1 software,and imported into the DAVID database for GO function and KEGG pathway enrichment analysis.Results A total of 135 valid prescriptions were included,involving 184 flavors of traditional Chinese medicines,with cold and mild properties.Sweet,bitter and pungent flavors,and the main attributes of lung,spleen,kidney,stomach and heart meridians.The association rules mined 14 pairs of commonly used medicine pairs.Cluster analysis clustered the top 20 traditional Chinese medicines into five cluster groups.Complex network visualization analysis formed a core prescription consisting of honey-fried licorice root,ginseng,rhizoma anemarrhenae,ophiopogon japonicus,poria cocos.The core prescription drugs were screened for 164 effective active ingredients,1,498 action targets,1,995 diabetes gene targets,404 intersecting targets,10 core targets were extracted,and a total of 1,363 items covering BP were obtained from GO functional enrichment analysis,129 items involving CC,264 items containing MF,and 206 items of KEGG signaling pathway.Conclusion The prescriptions and medicines used by Xin'an doctors in the treatment of diabetes mellitus reflect the academic idea of"treating both the symptoms and the root cause"as well as the therapeutic thought of"using cold and warmth,supplementing with sweetness and warmth,opening up and lowering with bitterness,cultivating the earth and generating gold,and consolidating the root and cultivating the elements",which provide references for the treatment of diabetes mellitus in today's clinics.

Objective:To explore the prognostic value of survival after veno-arterial ECMO (SAVE) score combined with 24-h lactate on the machine in patients with extracorporeal cardiopulmonary resuscitation (ECPR).Methods:Totally 59 patients treated with ECPR in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from April 2017 to June 2021 were retrospectively analyzed. According to the 28-day prognosis, the patients were divided into the death group ( n=36) and the survival group ( n=23). The differences in baseline data were analyzed, and multivariate logistic regression was performed to identify the influencing factors of 28-day mortality in patients with ECPR. The receiver operating characteristic (ROC) curve was applied to evaluate the predictive value of SAVE score, 24-h lactate and their combined detection for predicting 28-day mortality risk in patients with ECPR. Results:The 28-day survival rate of patients with ECPR was 39% (23/59). SAVE score of the death group was significantly lower than that of the survival group (-11.67±4.60 vs. -2.43±4.77, P<0.001), and the 24-h lactate in the death group was significantly higher than that in the survival group [5.94 (3.37, 12.40) mmol/L vs. 1.65 (1.07, 3.15) mmol/L, P<0.001]. Multivariate logistic regression analysis showed that SAVE score ( OR=0.703, 95% CI: 0.566-0.873, P=0.001) and 24-h lactate ( OR=1.608, 95% CI: 1.025-2.523, P=0.039) were independent influencing factors of 28-day mortality in ECPR patients. ROC curve analysis showed that the best cut-off value of SAVE score was -6, the sensitivity was 78.30% and specificity was 91.70%. The best cutoff value of 24-h lactate was 4.7 mmol/L, the sensitivity was 63.90% and specificity was 100.00%. The sensitivity and specificity of the combined detection of SAVE score and 24-h lactate were 82.60% and 100.00%, respectively. The area under the curve (AUC) of SAVE score combined with 24-h lactate for predicting the 28-day mortality risk in patients with ECPR was larger than that of SAVE score and 24-h lactate alone (0.952 vs. 0.917; 0.952 vs. 0.847). Conclusions:Lower SAVE score and higher 24-h lactate are independently risk factors of 28-day mortality in patients with ECPR, and SAVE score combined with 24-h lactate on the machine has a good predictive value for the prognosis of patients with ECPR.

Objective:To investigate the safety of early whole body computed tomography (WBCT) combined with coronary angiography (CAG) in patients with extracorporeal cardiopulmonary resuscitation (ECPR) and its application value in the diagnosis of cardiac arrest and complications of cardiopulmonary resuscitation (CPR).Methods:This was a retrospective study. Patients who underwent ECPR in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from January 2017 to July 2021 were enrolled in this research. Patients younger than 18 years or with incomplete clinical data were excluded. The results of WBCT and CAG examinations after ECPR were collected.Results:A total of 89 patients with ECPR, aged (47±17) years, were enrolled in the study, all underwent WBCT examination, and no adverse events such as ECMO and tracheal tube shedding occurred. WBCT found 7 cases of pulmonary embolism, 3 cases of aortic dissection and 2 cases of cerebral hemorrhage. WBCT identified CPR-related complications in 42 cases, including rib fractures ( n=20), pneumothorax ( n=5), mediastinal emphysema ( n=5), subcutaneous emphysema ( n=6), and hematoma or swelling at puncture site ( n=6). Fifty-five patients underwent CAG examination, the most common culprit vessels were the left anterior descending branch disease (58.2%) followed by the left circumflex branch disease (27.3%), the right coronary artery disease (21.8%) and left main artery disease (12.7%). Conclusions:Early WBCT and CAG examinations are of great significance and safety for the guidance of treatment in ECPR patients.

Objective:To analyze whether lower anticoagulation intensity can reduce the incidence of complications in patients with extracorporeal membrane oxygenation (ECMO).Methods:Clinical data of 88 non-cardiac surgery patients who received ECMO support for more than 72 h were collected in the Extracorpical Life support Center of Jiangsu Province Hospital from March 2015 to March 2021. According to the average activated partial thromboplastin time (APTT) level on the third day of ECMO, the patients were divided into the APTT < 50 s group ( n=53) and APTT ≥50 s group ( n=35). The venovenous ECMO (VV-ECMO) subgroup was divided into the APTT <50 s group ( n=23) and APTT ≥50 s group ( n=10). The venoarterial ECMO (VA-ECMO) subgroup was divided into the APTT <50 s group ( n=30) and APTT≥50 s group ( n=25). The average daily transfusion volume of red blood cells during ECMO, the incidence of bleeding, the incidence of thrombosis and all-cause mortality were compared between the two groups. Results:There were no significant differences in the incidence of thrombosis and all-cause mortality in the APTT <50 s group compared with the APTT ≥50 s group ( P>0.05), but the incidence of bleeding and the daily transfusion volume of red blood cells were significantly decreased (7.5% vs. 35.7%; 0.50 U vs. 0.88 U) ( P < 0.05). In 33 VV-ECMO patients, the all-cause mortality, incidence of bleeding, average daily transfusion volume of red blood cells in the APTT <50 s group were lower than those in the APTT ≥50 s group, and the incidence of thrombosis was higher, but there was no statistical difference between the two groups ( P>0.05). In the 55 VA-ECMO patients, there were no significant differences in all-cause mortality, incidence of bleeding, thrombosis and average daily transfusion volume of red blood cells between the two groups ( P > 0.05). Conclusions:The lower anticoagulation intensity in patients without anticoagulation can reduce the occurrence of bleeding in ECMO patients. It is reasonable for such patients to have a lower anticoagulation intensity and studies with larger sample size need to be carried out.

Objective:To investigate the distribution and antimicrobial resistance profile of clinical bacteria isolated from blood culture in China.Methods:The clinical bacterial strains isolated from blood culture from member hospitals of Blood Bacterial Resistant Investigation Collaborative System (BRICS) were collected during January 2018 to December 2019. Antibiotic susceptibility tests were conducted with agar dilution or broth dilution methods recommended by US Clinical and Laboratory Standards Institute (CLSI). WHONET 5.6 was used to analyze data.Results:During the study period, 14 778 bacterial strains were collected from 50 hospitals, of which 4 117 (27.9%) were Gram-positive bacteria and 10 661(72.1%) were Gram-negative bacteria. The top 10 bacterial species were Escherichia coli (37.2%), Klebsiella pneumoniae (17.0%), Staphylococcus aureus (9.7%), coagulase-negative Staphylococci (8.7%), Pseudomonas aeruginosa (3.7%), Enterococcus faecium (3.4%), Acinetobacter baumannii(3.4%), Enterobacter cloacae (2.9%), Streptococci(2.8%) and Enterococcus faecalis (2.3%). The the prevalence of methicillin-resistant S. aureus (MRSA) and methicillin-resistant coagulase-negative Staphylococcus were 27.4% (394/1 438) and 70.4% (905/1 285), respectively. No glycopeptide-resistant Staphylococcus was detected. More than 95% of S. aureus were sensitive to amikacin, rifampicin and SMZco. The resistance rate of E. faecium to vancomycin was 0.4% (2/504), and no vancomycin-resistant E. faecalis was detected. The ESBLs-producing rates in no carbapenem-resistance E. coli, carbapenem sensitive K. pneumoniae and Proteus were 50.4% (2 731/5 415), 24.6% (493/2001) and 35.2% (31/88), respectively. The prevalence of carbapenem-resistance in E. coli and K. pneumoniae were 1.5% (85/5 500), 20.6% (518/2 519), respectively. 8.3% (27/325) of carbapenem-resistance K. pneumoniae was resistant to ceftazidime/avibactam combination. The resistance rates of A. baumannii to polymyxin and tigecycline were 2.8% (14/501) and 3.4% (17/501) respectively, and that of P. aeruginosa to carbapenem were 18.9% (103/546). Conclusions:The surveillance results from 2018 to 2019 showed that the main pathogens of bloodstream infection in China were gram-negative bacteria, while E. coli was the most common pathogen, and ESBLs-producing strains were in majority; the MRSA incidence is getting lower in China; carbapenem-resistant E. coli keeps at a low level, while carbapenem-resistant K. pneumoniae is on the rise obviously.

Objective:To study the application of blood products in patients with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) and evaluate its effect on the prognosis.Methods:A total of 83 adult patients treated with VA-ECMO in the Emergency Department of the First Affiliated Hospital of Nanjing Medical University from January 2017 to January 2020 were grouped by survival to explore the risk factors of 28-day mortality using binary logistic regression, and the threshold was calculated by ROC curve.Results:Platelet transfusion ( OR=2.506, 95% CI: 1.142-5.499) and non-myocarditis disease ( OR=6.881, 95% CI: 1.615-29.316) were the risk factors of 28-day mortality in adult VA-ECMO patients. The threshold of platelet transfusion was 0.427 mL/(kg·d) (sensitivity 78.4%, specificity 69.6% , AUC 0.735). Conclusions:The increased platelet transfusion is related to the poor prognosis of adult patients with VA-ECMO. Refractory myocarditis patients are better treated with VA-ECMO.
