OBJECTIVE To investigate the improvement effect and potential mechanism of Qingxue xiaozhi jiangtang formula on insulin resistance （IR） in type 2 diabetes mellitus （T2DM） rats. METHODS T2DM rat model was established by intraperitoneal injection of 30 mg/kg streptozotocin combined with high-fat and high-sugar diet. The rats were randomly divided into normal control group， model group， Qingxue xiaozhi jiangtang formula low-dose and high-dose groups （6.525， 13.05 g/kg， calculated by raw material） and metformin group （positive control， 0.18 g/kg）， with 8 rats in each group. Administration groups were given relevant medicine intragastrically； normal control group and model group were given constant volume of normal saline intragastrically， once a day， for consecutive 6 weeks. Body mass and fasting blood glucose （FBG） were determined， and oral glucose tolerance test was conducted. Serum fasting insulin （FINS） level was measured to calculate the insulin resistance index （HOMA-IR） and insulin sensitivity index （ISI）. Additionally， the level of serum lipids， liver function， oxidative stress indicators and inflammatory factors were assessed. The phosphorylation levels of kinase R-like endoplasmic reticulum kinase （PERK） and forkhead box O1 （FOXO1） protein in liver tissue of rats were determined. RESULTS Compared with model group， the body weight， ISI， the levels of high-density lipoprotein cholesterol and superoxide dismutase were increased significantly in Qingxue xiaozhi jiangtang formula high-dose group and metformin group （P＜0.05）； FBG， blood glucose level at 120 minutes of glucose loading， area under the curve of glucose， FINS， HOMA-IR， low-density lipoprotein cholesterol， total cholesterol， triglyceride， alanine transaminase， aspartate transaminase， alkaline phosphatase， malondialdehyde， interleukin-6， tumor necrosis factor-α， and C-reactive protein levels were significantly reduced （P＜ Δ0.05）； the pathological damage of liver tissue had significantlyimproved， and the phosphorylation levels of PERK and FOXO1 proteins in liver tissue were significantly decreased （P＜0.05）. CONCLUSIONS Qingxue xiaozhi jiangtang formula can regulate glucose and lipid metabolism， inflammation factor and oxidative stress levels， and alleviate insulin resistance in T2DM rats. Its mechanism of action may be related to the inhibition of the PERK/FOXO1 signaling pathway.

The establishment of an intelligent audit system for hospital medical insurance is crucial for standardizing irrational practices and curbing the unwarranted escalation of medical insurance costs. A tertiary hospital has developed comprehensive prescription review rules in terms of indications, nutritional risk assessments, pain score evaluations, drug sensitivity test results, and target patient populations. When using medical insurance funds for settlement, both systematic and manual reviews are conducted, and three-level intervention measures such as " prompt, review, and interception" are implemented based on prescription issues. After the system was put into use, the hospital′s in-process information system supervision mode shifted from the previous focus on prompts to focus on audits. The medical insurance intelligent audit system provided timely prompts and interventions, and the number of unreasonable medical insurance prescriptions and deductions from medical insurance sampling prescriptions significantly decreased ( P<0.001), while the number of medical insurance medication prescription audits increased ( P<0.001). The application of the intelligent medical insurance medication audit system has improved the efficiency of prescription auditing and ensured the rationality of the use of medical insurance funds.

Objective To analysis the effectiveness and cost of Internet-based anticoagulation clinic versus traditional anticoagulation clinic treatment at Nanjing Drum Tower Hospital during the COVID-19 pandemic.Methods We reviewed and analyzed the clinical data of patients receiving anticoagulation management through Internet-based outpatient care and traditional outpatient care in Nanjing Drum Tower Hospital,from June 1,2020 to June 30,2021.Variability in time in therapeutic range(TTR)and international normalized ratio(INR)were calculated for enrolled patients.Patients meeting TTR≥60%and INR variability<0.65 were considered optimal anticoagulation quality.Cost-effectiveness analysis was conducted from the patients'perspective,with results expressed using the incremental cost-effectiveness ratio(ICER).Results In the"Internet-based anticoagulation outpatient care"and"traditional face-to-face anticoagulation outpatient care"groups,19 individuals(67.86%)and 67 individuals(76.14%)met the criteria for optimal anticoagulation quality,respectively.The mean TTR was(71.83±19.17)%in the Internet-based group and(71.74±23.41)%in the traditional face-to-face group,indicating similar levels of warfarin anticoagulation quality between the two groups.The ICER was calculated as 327.17 yuan,less than the per capita gross domestic product(GDP)of 2021.Conclusion During the COVID-19 pandemic,Nanjing Drum Tower Hospital's Internet-based anticoagulation outpatient care effectively complemented the government's epidemic control policies.It ensured equivalent anticoagulation outcomes and significantly reduced patients'financial burdens.This approach offers new insights and guidance for optimizing healthcare services in the post-pandemic era.

Objective To evaluate the relationship between ceftazidime-avibactam(CAZ-AVI)blood concentrations and efficacy in critically ill patients and to investigate the factors influencing blood levels.Methods The CAZ-AVI trough concentrations(Cmin)were detected in 29 patients who received CAZ-AVI treatment for at least 48 hours.The clinical materials of the patients were collected together for retrospective analysis.Results The Cmin of ceftazidime(CAZ)and avibactam(AVI)were(50.95±5.17)and(7.52±0.96)mg·L-1 in the effective group and(31.16±7.03)and(5.37±1.32)mg·L-1 in the ineffective group,respectively.The Cmin of CAZ in the effective group was significantly higher than in the ineffective group(P<0.05),and there was no significant difference in AVI Cmin between the two groups(P>0.05).Spearman's correlation analysis showed that CAZ Cmin was positively correlated with clinical efficacy(P<0.05),and no correlation between AVI Cmin and clinical efficacy(P>0.05).The optimal CAZ Cmin threshold was 24.59 mg·L-1.Multiple linear regression analysis showed that age and creatinine clearance was significantly correlated with the Cmin of CAZ,and creatinine clearance was significantly correlated with AVI Cmin(P<0.05).Conclusions The Cmin of CAZ correlates with efficacy,and it may be more beneficial for clinical treatment to keep the concentration of CAZ-AVI always greater than the minimum inhibitory concentration during the dosing interval.The creatinine clearance should be fully considered when optimizing CAZ-AVI dosage in critically ill patients.

Uncontrolled hypertension in the perioperative period may affect the hemodynamic stability of patients during surgery and thus affect the prognosis of patients.This increases the risk of other complications and death.For hypertensive patients undergoing surgery,it is necessary to weigh the pros and cons,and choose appropriate antihypertensive drugs to reduce the incidence of perioperative adverse events.There is no unified conclusion on perioperative blood pressure management in China.This paper systematically reviewed the perioperative blood pressure control objectives and drug use programs,including non-cardiac surgery,cardiac surgery,pregnancy,and pheochromocytoma.It provided a reference for the perioperative management of hypertensive patients.

Polymyxins are the first-line drugs used in multidrug resistance(MDR)Gram-negative infections.Polymyxin-induced nephrotoxicity is the major dose-limiting factor hindering its clinical use.It has been suggested that the mechanism of polymyxin-associated nephrotoxicity is related to its accumulation in the kidney upon extensive reabsorption from renal proximal tubular cells,and one or more renal transporters may mediate the process that polymyxins enter the renal tubular cells across cytomembrane.This review aimed to describe the roles of renal transporters in polymyxins reabsorption into the renal tubular cells and provide reference for reducing the nephrotoxicity of polymyxin.

Myocardial infarction is the most common cause of heart failure,and myocardial remodeling can occur after infarction,thus contributing to the progression of heart failure.The occurrence of post-infarction ventricular remode-ling is closely related to m6A methylation.m6A methylation is a reversible and highly dynamic process.This process is mainly mediated by m6A methylation positive and negative regulatory enzymes and is involved in the occurrence of post-in-farction myocardial remodeling through mechanisms such as cellular autophagy.This article mainly reviews relevant litera-ture in recent years.Firstly,a brief introduction is given to m6A methylation,followed by an introduction to the role of m6A methylase in regulating myocardial remodeling.Finally,a summary analysis is conducted on the mechanism of m6A methylation in regulating myocardial remodeling from the perspectives of autophagy,inflammation,cell apoptosis,calcium ion homeostasis,extracellular matrix remodeling,and ferroptosis.The feasibility of using m6A methylation serological de-tection as a diagnostic tool for myocardial remodeling after myocardial infarction is discussed,in order to provide reference for related research.

Objectives To investigate the relationship between self-reported occupational noise exposure and levels of plasma inflammatory cytokines in asthmatic patients. Methods A total of 910 adult asthmatic patients were selected as the study subjects, and their occupational noise exposure history and other related information were collected. The peripheral blood samples were collected from the patients, and the expression levels of plasma soluble CD14 (sCD14), complement factor D (CFD), Eotaxin-11 (CCL11), and IL-9 were determined. The relationship between self-reported occupational noise exposure and the expression levels of the four inflammatory cytokines in patients’ plasma were analyzed using multiple linear regression models. The interactions between confounding factors and self-reported occupational noise exposure were further analyzed by interaction analysis. Results The plasma CCL11, sCD14 and CFD expressions in asthmatic patients with self-reported occupational noise exposure were significantly higher than those in patients without the exposure (P<0.05). After adjusting for confounding factors, compared with patients reporting no occupational noise exposure, the plasma CFD expression was increased by 0.17 (95% CI: 0.02, 0.31) natural logarithm units in patients with self-reported occupational noise exposure. During remission, the levels of plasma CCL11 and sCD14 in asthmatic patients with self-reported occupational noise exposure were increased by 0.27 (95% CI: 0.05, 0.49) and 0.22 (95% CI: 0.02, 0.41) natural logarithm units, respectively, when compared with patients without the exposure. Interaction analysis showed that self-reported occupational noise exposure had significant multiplicative interaction with smoking or pet ownership on plasma CCL11 or CFD expressions in asthmatic patients (all P<0.05). Conclusion Self-reported occupational noise exposure is significantly associated with increased expression levels of plasma CFD, CCL11, and sCD14 in adult asthmatic patients.

Objective:To explore the effective components and potential mechanisms of Xiefei Lishui Prescription in the treatment of heart failure.Methods:Ultra high-performance liquid chromatography tandem four stage rod time of flight mass spectrometry (UPLC-Q-TOF-MS) technology was used to analyze and identify the active components of Xiefei Lishui Prescription. Drug targets were predicted through the Swiss Target Prediction database, and disease targets were collected from Gene Cards, Dis GENET, and TTD databases.

Background Salidroside (SAL) has a protective effect on multiple organ systems. Exposure to fine particulate matter (PM_2.5) in the atmosphere may lead to disruptions in gut microbiota and impact intestinal health. The regulatory effect of SAL on the gut microbiota of mice exposed to PM_2.5 requires further investigation. Objective To evaluate gut microbiota disruption in mice after being exposed to PM_2.5 and the potential effect of SAL. Methods Forty male C57BL/6 mice, aged 6 to 8 weeks, were randomly divided into four groups: a control group, an SAL group, a PM_2.5 group, and an SAL+PM_2.5 group, each containing 10 mice. In the SAL group and the SAL+PM_2.5 group, the mice were administered SAL (60 mg·kg⁻¹) by gavage, while in the control group and the PM_2.5 group, sterile saline (10 mL·kg⁻¹) was administered by gavage. In the PM_2.5 group and the SAL+PM_2.5 group, PM_2.5 suspension (8 mg·kg⁻¹) was intratracheally instilled, and in the control group and SAL group, sterile saline (1.5 mL·kg⁻¹) was intratracheally administered. Each experiment cycle spanned 2 d, with a total of 10 cycles conducted over 20 d. Histopathological changes in the ileum tissue of the mice were observed after HE staining. Colon contents were collected for gut microbiota sequencing and short-chain fatty acids (SCFAs) measurements. Results The PM_2.5 group showed infiltration of inflammatory cells in the ileum tissue, while the SAL+PM_2.5 group exhibited only a small amount of inflammatory cell infiltration. Compared to the control group, the PM_2.5 group showed decreased Shannon index (P<0.05) and increased Simpson index (P<0.05), indicating that the diversity of gut microbiota in this group was decreased; the SAL+PM_2.5 group showed increased Shannon index compared to the PM_2.5 group (P<0.05) and decreased Simpson index (P<0.05), indicating that the diversity of gut microbiota in mice intervened with SAL was increased. The principal coordinates analysis (PCoA) revealed a significant separation between the PM_2.5 group and the control group, while the separation trend was less evident among the control group, the SAL group, and the SAL+PM_2.5 group. The unweighted pair-group method with arithmetic means (UPGMA) clustering tree results showed that the control group and the SAL group clustered together first, followed by clustering with the SAL+PM_2.5 group, and finally, the three groups clustered with the PM_2.5 group. The PCoA and UPGMA clustering results indicated that the uniformity and similarity of the microbiota in the PM_2.5 group were significantly decreased. Compared to the control group, the PM_2.5 group showed decreased abundance of phylum Bacteroidetes and Candidatus_Saccharimonas (P<0.05) and increased abundance of phylum Proteobacteria, genus Escherichia, genus Bacteroides, genus Prevotella, genus Enterococcus, and genus Proteus (P<0.05). Compared to the PM_2.5 group, the SAL+PM_2.5 group showed decreased abundance of phylum Proteobacteria, phylum Actinobacteria, genus Prevotella, and genus Proteus (P<0.05), and increased abundance of Candidatus_Saccharimonas (P<0.05). The PM_2.5 group showed reduced levels of propionic acid, valeric acid, and hexanoic acid compared to the control group (P<0.05), while the SAL+PM_2.5 group showed increased levels of propionic acid, isobutyric acid, butyric acid, valeric acid, and hexanoic acid compared to the PM_2.5 group (P<0.05). Conclusion Exposure to PM_2.5 can cause pathological alterations, microbial dysbiosis, and disturbing production of SCFAs in intestinal tissue in mice. However, SAL can provide a certain degree of protective effect against these changes.
