OBJECTIVE To form an expert consensus on the clinical application of parenteral direct thrombin inhibitors （DTIs） in patients during the perioperative period. METHODS Led by Sichuan Academy of Medical Sciences & Sichuan Provincial People’s Hospital （the Affiliated Hospital of UESTC）， a multidisciplinary working group was established. Through literature review and the Delphi method， clinical questions related to the rational perioperative use of parenteral DTIs were identified. A structured design was adopted using the “Population-Intervention-Comparison-Outcome” framework； systematic searches were conducted in CNKI， Medline， Embase and other databases. Relevant evidence from randomized controlled trials and cohort studies was included and synthesized. Evidence quality was assessed using the Grades of Recommendations Assessment，Development and Evaluation （GRADE） approach， and recommendations were formulated through multiple rounds of Delphi surveys and expert consensus meetings. RESULTS &CONCLUSIONS Seven recommendations （each with an expert consensus rate exceeding 90%） on the use of parenteral DTIs in perioperative patients were developed. These recommendations specify drug selection， dosing ranges， key monitoring points， and safety management strategies for parenteral DTIs in various scenarios， including the perioperative period of ventricular assist device implantation， the perioperative period of cardiac surgery， perioperative patients with lower-extremity atherosclerotic disease， the perioperative period of percutaneous coronary intervention in patients with acute coronary syndrome， the perioperative period of carotid artery stenting in patients with carotid stenosis， the perioperative period of patients with right heart thrombosis， and patients who develop related thrombosis and dysfunction after a central venous catheter insertion. In addition， warning and management pathways for perioperative bleeding and thrombotic events were proposed. This expert consensus， which is formulated based on the best available evidence， provides evidence-based guidance for standardized and individualized use of parenteral DTIs in perioperative period.

Janus kinase inhibitors (JAKi) are a kind of small molecule targeted drugs used to treat a variety of immune-mediated inflammatory diseases by inhibiting the excessive response of a variety of cytokines. Currently, JAKi has shown good clinical efficacy, but it also has risk of major adverse cardiovascular events (MACE). The specific mechanism of JAKi-caused MACE is still unclear. This paper reviews the pharmacological molecular mechanisms and classification of JAKi and the research progress of MACE related to the JAKi (tolvaptan, baricitinib, ruxolitinib, upadacitinib, and abrocitinib) that have been approved for marketing in China. The risk factors that lead to MACE, including age, combined cardiovascular disease and inflammatory diseases, types of JAKi, dosage forms, and treatment duration are analyzed, so as to provide reference for the clinical rational use of JAKi and better prevention of MACE related to JAKi.

Objective To investigate and analyze the epidemiological characteristics and the causes of a suspected outbreak of carbapenem-resistant Acinetobacter baumannii(CRAB)infection,and provide basis for healthcare-asso-ciated infection(HAI)prevention and control.Methods Information of 3 patients with CRAB positive culture from the respiratory intensive care unit(RICU)of a hospital in May 2024 was collected.Microbiological sampling was performed in patients' ward environment,and the specimens were cultured and strains were identified.CRAB strains detected from the environment and patients were performed whole genome sequencing(WGS).Multiple de-partments jointly formulated and implemented comprehensive infection control measures,and the effectiveness were evaluated.Results CRAB was cultured from specimens of sputum and bedside office mice of 3 patients.WGS de-tection showed that ST2158 and ST1791 resistance genes were detected from both sputum and bedside office mice of 2 patients.After comprehensive assessment,2 patients were confirmed with HAI and 1 patient was confirmed with colonization,ruling out an outbreak of HAI.A total of 24 environmental specimens were taken for environmental hygiene monitoring,with a CRAB detection rate of 58.33％.CRAB detected from bedside mice and patients' spu-tum specimen had consistent CRAB drug susceptibility testing results.After implementing measures such as in-creasing the frequency of cleaning and disinfection of ward environment,strengthening the implementation of hand hygiene,and enhancing the supervision of department personnel as well as HAI prevention and control training,HAI was effectively controlled.Conclusion The possible transmission route of this suspected CRAB outbreak in RICU is the contamination of office mice,which caused healthcare workers carrying CRAB in their hands,leading to cross infection due to poor hand hygiene implementation of healthcare workers.Strengthening the cleaning and dis-infection of environmental surface and the management of hand hygiene of healthcare workers are key measures to prevent CRAB HAI.

Objective:To analyze the symptoms,diagnosis and treatment of upper urinary tract calculi patients combined with mild and moderate benign prostatic hyperplasia(BPH)after ureteral stent implantation.Methods:One hundred and six BPH pa-tients who were hospitalized for upper urinary tract calculi and had ureteral stents retained from January 2019 to December 2022 were selected and divided into 2 weeks group and 4 weeks group according to the time of removal of ureteral stents after surgery.Their gener-al clinical data were analyzed and compared.International Prostatic Symptom Scale(IPSS),postoperative ureteral Stent Symptom Questionnaire(USSQ),and incidence of adverse events after ureteral stent removal were recorded before and after removal.Results:The scores of IPSS were significantly increased in all patients,and symptoms in urinary tract had improved significantly after discharge(P＜0.05).Compared with the 2 weeks group,the USSQ score of the 4 weeks group was significantly increased(P＜0.05).And no significant adverse event was observed in the 2 weeks group after the removal of ureteral sten.Conclusion:IPSS score and USSQ score increased significantly during stent implantation in BPH patients with lithiasis.And complications increased sig-nificantly over time.Following thorough clinical assessment,early ureteral stent removal demonstrates both safety and efficacy,repre-senting an optimal therapeutic approach in selected cases.

To report 3 cases of acute generalized exanthematous pustulosis (AGEP) caused by hydroxychloroquine. All the 3 patients were females, aged 23, 30, and 28 years respectively. In cases 1 and 3, the rashes appeared 4 days and 12 days respectively after the treatment with hydroxychloroquine for systemic lupus erythematosus; case 2, who was 8 weeks pregnant, developed rashes 10 days after starting hydroxychloroquine treatment for antiphospholipid syndrome. All the 3 patients had high fever, and clinically presented with generalized round or oval-shaped edematous erythema on the face, neck, trunk and limbs, covered with a large number of pinhead-sized pustules, and with multiple erythema multiforme-like lesions on the trunk and both upper limbs, including targetoid lesions. Mutations in the IL36RN gene were identified in all the 3 patients: a homozygous mutation c.115+6T>C in the IL36RN gene was found in case 1, and her parents were heterozygous carriers; case 2 inherited the heterozygous mutation c.115+6T>C in the IL36RN gene from her mother; the heterozygous mutation c.115+6T>C found in case 3 was a de novo mutation. A diagnosis of AGEP was made in all the 3 cases. Cases 1 and 2 received subcutaneous injections of adalimumab in addition to the treatment of their underlying diseases, and skin lesions markedly regressed after 1 week of treatment; case 3 was treated with high-dose glucocorticoids, and lesions subsided after 4 weeks; no significant adverse reactions were observed in cases 1 and 2, however, femoral head necrosis was noted in case 3. During a follow-up period of 42 months, none of the patients experienced recurrence, and case 2 gave birth to a healthy baby boy after 8-month treatment.

Objective To investigate the incidence and economic burden of healthcare-associated infection(HAI)in patients after liver transplant.Methods Basic clinical information,infection status,and related medical expenses of liver transplant patients in the department of hepatobiliary surgery in a tertiary first-class hospital from November 2012 to December 2023 were investigated retrospectively.A case-control study design was employed,with post-li-ver transplant patients who developed HAI as the infection group and those without HAI during the same period as the control group.The 1∶1 propensity score matching(PSM)method was adopted(caliper value was set at 0.05,employing sampling without replacement).Length of hospital stay and hospitalization expenses between patients in the infection group and the control group were compared using Wilcoxon rank-sum test,and the economic burden due to HAI was calculated.Results A total of 336 liver transplant patients were included in study,out of which 48 had HAI,with an incidence of 14.29％.44 pairs were successfully matched by PSM.After matching,the median hospitalization expense for patients in the infection group was 334 473.73 Yuan,while that of the control group was 285 824.82 Yuan,with a statistically significant difference(Z=-3.430,P＜0.05).The direct economic burden of HAI in liver transplant patients was 48 648.91 Yuan.After matching,the median length of hospital stay in the in-fection group(37.0 days)was 12.5 days longer than that in the control group(24.5 days),with statistically sig-nificnat difference(Z=-3.630,P＜0.001).Conclusion HAI after liver transplant increases patients' hospitaliza-tion expense and prolongs their hospital stay,thus brings huge economic burdens to the patients.
