Glucagon-like peptide-1 ( GLP-1 ) is secreted by gut enteroendocrine cells. GLP-1 receptor agonists ( GLP-1 RAs) control glucose-related augmentation of insulin and suppress glu-cagon secretion. GLP-lRAs also inhibit gastric emptying, food intake and limit weight gain. In the past decade, significant progresses have been made in the investigation on the effects of GLP-1 RAs on cardiovascular system. The potential advantages of oral small-molecule GLP-1 RAs could improve the application of this class of drugs. This review highlights the multiple cardiovascular profiles of GLP-1 RAs in the treatment of cardiovascular diseases to provide new insights into cardiovascular benefits of GLP-1 RAs.

Objective To analyze the clinical outcomes of extended thymectomy for myasthenia gravis (MG) patients under different surgical approaches, and to determine the factors affecting the prognosis of MG. Methods The MG patients who underwent extended thymectomy from January 2014 to March 2021 in our hospital were retrospectively collected. According to the surgical approach, they were divided into a subxiphoid group and an intercostal group, and the perioperative results and prognosis were compared between the two groups. A “good outcome” was defined as complete stable remission (CSR), pharmacological remission (PR) or minimal manifestations state (MMS); a “poor outcome” was defined as outcomes worse than MMS. Univariate and multivariate logistic regression analyses were performed to assess the factors associated with the good outcomes. Results A total of 187 MG patients were included in the study, including 82 males and 105 females, with a median age of 50 (36, 60) years. There were 134 patients in the intercostal group and 53 patients in the subxiphoid group. Compared with the intercostal group, although the operation time of the subxiphoid group was longer [200.0 (172.0, 232.0) min vs. 141.0 (118.0, 169.0) min, P<0.001], the intraoperative blood loss was less [10.0 (10.0, 20.0) mL vs. 20.0 (10.0, 50.0) mL, P<0.001], the postoperative hospital stay was shorter [3.0 (2.5, 4.0) d vs. 5.0 (3.0, 7.0) d, P<0.001], and the incidence of complications was lower [1 (1.9%) vs. 26 (19.4%), P=0.001]. A total of 159 (85.0%) patients were followed up for a median period of 46 (13, 99) months, with a good outcome rate of 90.6% and CSR rate of 33.3%. There were no statistical differences in PR, MMS or overall good outcome rates between the two groups (P>0.05). Multivariate logistic analysis showed that age≤50 years was an independent predictor for "good outcome" of MG patients. Conclusion Extended thymectomy via subxiphoid for MG is a safe, feasible and effective surgical approach.

Objective:To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application.Methods:A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1∶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively.Results:A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] ( Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=-2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ 2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference ( Z=-0.78, P=0.439). Conclusions:Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.

Objective As primary Sj?gren's syndrome(pSS)primarily affects the salivary glands,saliva can serve as an indicator of the glands'pathophysiology and the disease's status.This study aims to illustrate the salivary proteomic profiles of pSS patients and identify potential candidate biomarkers for diagnosis. Methods The discovery set contained 49 samples(24 from pSS and 25 from age-and gender-matched healthy controls[HCs])and the validation set included 25 samples(12 from pSS and 13 from HCs).Totally 36 pSS patients and 38 HCs were centrally randomized into the discovery set or to the validation set at a 2:1 ratio.Unstimulated whole saliva samples from pSS patients and HCs were analyzed using a data-independent acquisition(DIA)strategy on a 2D LC-HRMS/MS platform to reveal differential proteins.The crucial proteins were verified using DIA analysis and annotated using gene ontology(GO)and International Pharmaceutical Abstracts(IPA)analysis.A prediction model for SS was established using random forests. Results A total of 1,963 proteins were discovered,and 136 proteins exhibited differential representation in pSS patients.The bioinformatic research indicated that these proteins were primarily linked to immunological functions,metabolism,and inflammation.A panel of 19 protein biomarkers was identified by ranking order based on P-value and random forest algorichm,and was validated as the predictive biomarkers exhibiting good performance with area under the curve(AUC)of 0.817 for discovery set and 0.882 for validation set. Conclusions The candidate protein panel discovered may aid in pSS diagnosis.Salivary proteomic analysis is a promising non-invasive method for prognostic evaluation and early and precise treatments for pSS patients.DIA offers the best time efficiency and data dependability and may be a suitable option for future research on the salivary proteome.

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.

Objective:To investigate the expression level,clinical significance and function of circular RNAs(circRNAs)circ_0073585 in the bone marrow of patients with acute myeloid leukemia(AML).Methods:The expression levels of circ_0073585 in bone marrow samples of 106 newly diagnosed AML patients and 38 controls were detected by real-time quantitative PCR(RQ-PCR).The differences were compared between the two groups and their clinical significance was analyzed.The diagnostic value of circ_0073585 expression for AML was evaluated by receiver operating characteristic curve(ROC).THP-1 cells with lentivirus overexpressing circ_0073585 vector and empty vector were divided into two groups:circ_0073585-THP-1 and NC-THP-1 group.CCK-8 assay and flow cytometry were used to study the effects of circ_0073585 on THP-1 cell proliferation,survival,apoptosis and drug sensitivity.Results:Compared with the controls,the expression level of circ_0073585 in the bone marrow of AML patients was significantly reduced(P＜0.001).There was a statistically significant difference between the high and low expression groups of circ_0073585 in the white blood cell count,platelet count(P＜0.01)and chromosome risk(P＜0.05).Compared with NC-THP-1 cells,the proliferation and viability of circ_0073585-THP-l cells were weakened(P＜0.01),the apoptosis rate was increased(P＜0.01),and the sensitivity to homoharringtonine(P＜0.05)and daunorubicin hydrochloride(P＜0.001)was increased.Conclusion:The expression level of circ_0073585 is decreased in AML patients.Overexpression of circ_0073585 can inhibit the proliferation and viability of leukemic cells,promote apoptosis,and increase sensitivity of leukemia cells to chemotherapy drugs.

Aim To investigate the effect of Xuanfuhua decoction combined with sorafenib on liver cancer bearing mice and the underlying mechanism.Methods KM mice were divided into the liver cancer group,Xuanfuhua decoction group,sorafenib group,combina-tion group,combination+PTEN inhibitor(BPV)group,combination+PI3K activator(IGF-1)group and blank group.Liquid chromatography-mass spec-trometry was used to detect the blood components of Xuanfuhua decoction in serum of mice in liver cancer group and Xuanfuhua decoction group.The changes of serum ALT,AST,tumor weight and tumor volume were detected.The pathological changes of tumor tissue,the proportion of TUNEL,p53 and Bax positive cells,the levels of IFN-γ and TNF-α,and the protein changes of PTEN,p-PI3K and p-AKT were detected.The effects of combined treatment on the proliferation and apopto-sis of H22 cells of mouse hepatoma were observed in vitro.Results There were 11 constituents absorbed into blood of Xuanfuhua decoction.Compared with the liver cancer group,the tumor cells in the Xuanfuhua decoction group,sorafenib group,and combination group were dispersed,the serum AST and ALT levels,tumor weight,tumor volume,and p-PI3K and p-AKT proteins decreased,the proportion of TUNEL,p53 and Bax positive cells,IFN-γ,TNF-α levels,and PTEN protein in tumor tissue increased,and the trend of the combination group was the most obvious(P＜0.05).BPV or IGF-1 reversed the anti-tumor effect of the combined treatment on liver cancer bearing mice.In vitro experiments showed that the combined treatment could inhibit the proliferation of H22 cells and promote the apoptosis of H22 cells better than Xuanfuhua de-coction or sorafenib alone.BPV or IGF-1 reversed the effects of combined treatment on the proliferation and apoptosis of H22 cells.Conclusion Xuanfuhua de-coction combined with sorafenib may exert anti-tumor effect on liver cancer bearing mice by up-regulating PTEN and inhibiting PI3K/AKT pathway.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective: To analyze and compare therapy responses, outcomes, and incidence of severe hematologic adverse events of flumatinib and imatinib in patients newly diagnosed with chronic phase chronic myeloid leukemia (CML) . Methods: Data of patients with chronic phase CML diagnosed between January 2006 and November 2022 from 76 centers, aged ≥18 years, and received initial flumatinib or imatinib therapy within 6 months after diagnosis in China were retrospectively interrogated. Propensity score matching (PSM) analysis was performed to reduce the bias of the initial TKI selection, and the therapy responses and outcomes of patients receiving initial flumatinib or imatinib therapy were compared. Results: A total of 4 833 adult patients with CML receiving initial imatinib (n=4 380) or flumatinib (n=453) therapy were included in the study. In the imatinib cohort, the median follow-up time was 54 [interquartile range (IQR), 31-85] months, and the 7-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.2%, 88.4%, 78.3%, and 63.0%, respectively. The 7-year FFS, PFS, and OS rates were 71.8%, 93.0%, and 96.9%, respectively. With the median follow-up of 18 (IQR, 13-25) months in the flumatinib cohort, the 2-year cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) were 95.4%, 86.5%, 58.4%, and 46.6%, respectively. The 2-year FFS, PFS, and OS rates were 80.1%, 95.0%, and 99.5%, respectively. The PSM analysis indicated that patients receiving initial flumatinib therapy had significantly higher cumulative incidences of CCyR, MMR, MR(4), and MR(4.5) and higher probabilities of FFS than those receiving the initial imatinib therapy (all P<0.001), whereas the PFS (P=0.230) and OS (P=0.268) were comparable between the two cohorts. The incidence of severe hematologic adverse events (grade≥Ⅲ) was comparable in the two cohorts. Conclusion: Patients receiving initial flumatinib therapy had higher cumulative incidences of therapy responses and higher probability of FFS than those receiving initial imatinib therapy, whereas the incidence of severe hematologic adverse events was comparable between the two cohorts.

Aim To explore the mechanism of process¬ing and increasing efficiency of Arisaematis rhizomz preparatum. Methods UPLC-Q-TOF-MS/MS tech¬nology was used to detect the chemical components be¬fore and after processing of Arisaematis rhizomz prepara¬tum, and its mechanism of action was analysed in the treatment of 44 asthma and phlegm " by using network pharmacology. A rat model of allergic asthma was es- tablished to compare the efficacy of Arisaematis rliizoma before and after processing. Results A total of 27 chemical components were identified, among which cur- cumin ,6-gingerol and other components increased after processing. Combined with the database prediction, the action mechanism of the 36 chemical components in the treatment of 44 asthma and phlegm" diseases was dis¬cussed and predicted through network pharmacology. The results of animal experiments showed that the effect of processed Arisaematis rhizoma on allergic asth¬ma was better than that of Arisaematis rhizoma, but there was no significant difference. Conclusions The addition of curcumin, 6-gingerol, camphor, demethyl- curcumin and other components after the processed Ari¬saematis rhizomz preparatum may be the reason for the synergistic effect of Arisaematis rhizomz preparatum in the treatment of allergic asthma.
