The clinical diagnosis and treatment of urinary tract infection has long faced the challenges of insufficient standardization of diagnosis and treatment pathways,irrational use of antimicrobial drugs and high recurrence rate.How to optimize the hierarchical diagnosis and treatment pathway of urinary tract infection,standardize the use of antimicrobial drugs,and reduce the recurrence rate have always been the focus of clinical attention.There is significant heterogeneity in the existing diagnostic criteria for urinary tract infection,which seriously affects the comparability and evidence integration of clinical and research studies.In order to solve the above problems,a consensus on global multidisciplinary diagnostic criteria for urinary tract infection has been formed by international multidisciplinary experts after three rounds of Delphi method.Breaking through the traditional classification framework,the consensus innovatively established a four-dimensional quantitative scoring system including local symptoms and signs,systemic inflammatory response,quantitative analysis of pyuria and urine culture results,and established a hierarchical standard for stepwise urinary tract diagnosis according to the scoring threshold.Based on the key citations related to the consensus,this paper interprets in detail the basis for the selection of core indicators and the establishment of thresholds for the diagnosis of urinary tract infection in the consensus,and focuses on the key issues and implementation paths of the consensus in localization practice.This consensus provides a unified standard for standardizing the clinical diagnosis and treatment of urinary tract infection,improving the homogeneity of clinical research through standardized diagnostic processes,and promoting the standardization of UTI drug research and development and the rational use of antibiotics and precision.

Osteonecrosis of the femoral head(ONFH)is a disabling orthopedic disease,pathologically characterized by progressive collapse of the femoral head accompanied by destruction of the trabecular and articular cartilage structures,leading to hip joint pain and progressive functional impairment.Bone marrow mesenchymal stem cell-derived extracellular vesicles(BMSC-EVs)show great promise in tissue repair and regeneration,with low immunogenicity and tumorigenicity,and play roles in osteogenesis,angiogenesis,and immunomodulation.This review summarizes the therapeutic effects and underlying mechanisms of BMSC-EVs in ONFH,providing a theoretical basis for its treatment.

Internal carotid artery(ICA)occlusion is one of the main causes of ischemic stroke.Endovascular treatment is one of the main surgical methods for symptomatic non-acute ICA occlusion.However,how to optimize the surgical strategy to improve the success rate of recanalization of occluded vessels require further exploration.The authors reported a case of subacute ICA occlusion treated with endovascular treatment.During the operation,intravascular ultrasound(IVUS)was used for high-resolution and precise assessment of the lumen morphology,plaque characteristics and vessel wall structure in the occluded segment.The surgical strategy was individualized,ultimately achieving successful recanalization of the occluded vessel.Combined with literature review of the clinical characteristics of subacute ICA occlusion and the application of IVUS in this type of lesion,in order to provide reference and inspiration for further optimization of interventional surgical strategies.

BACKGROUND:Croton cream can activate ERK pathways and have anti-apoptotic effects on neuronal cells.It is not clear whether it synergistically exerts anti-apoptotic effects by inhibiting the activation of JNK and p38 pathways. OBJECTIVE:To explore the effects and mechanisms of croton cream on neuronal damage and apoptosis in the ischemic cortex of rats with cerebral ischemia-reperfusion injury. METHODS:(1)Ninety Sprague-Dawley rats were randomly divided into sham operation group,model group,croton cream low-dose group,croton cream medium-dose group,croton cream high-dose group and nimodipine group,with 15 rats in each group.Except for the sham operation group,animal models of middle cerebral artery occlusion were prepared in rats by the thread method.Rats in the three croton cream groups were given 20,40,and 60 mg/kg croton cream,respectively.Rats in the sham operation and model groups were given the same amount of normal saline,once a day,for 7 consecutive days.The optimal concentration of croton cream,namely the high dose of croton cream,was selected based on neurological deficit score,TTC staining,brain tissue water content,hematoxylin-eosin staining and Nissl staining.(2)Another 120 Sprague-Dawley rats were randomly divided into sham operation group,model group,croton cream group,JNK inhibitor group,croton cream+JNK inhibitor group,p38 MAPK inhibitor group,croton cream+p38 MAPK inhibitor group,and nimodipine group,with 15 rats in each group.Animal models of middle cerebral artery occlusion were prepared using the thread method in all the groups except in the sham operation group.Thirty minutes before modeling,10 μL of SP600125(JNK inhibitor)and 10 μL of SB203580(p38 MAPK inhibitor)were injected into the lateral ventricle of the rats,respectively.Rats in croton cream groups were intragastrically given 60 mg/kg croton cream.Seven days later,the JNK/p38 MAPK signaling pathway,apoptosis-related proteins and cell apoptosis were detected by western blot,TUNEL staining and flow cytometry,respectively. RESULTS AND CONCLUSION:(1)Compared with the sham operation group,neurological deficit score,cerebral water content,cerebral infarction volume and apoptosis rate were significantly increased in the model group(P<0.05),where nerve cells showed scattered distribution.Compared with the model group,neurological deficit score,water content of brain tissue and cerebral infarction volume were significantly decreased in the croton cream medium-dose group,high-dose group and nimodipine group(P<0.05),and the pathological morphology of nerve cells was significantly improved.(2)Compared with the JNK inhibitor group,p-JNK/JNK,p-p38/p38 and Bax expressions in rat brain tissue and the apoptotic rate were significantly decreased in the croton cream+inhibitor groups(P<0.05),while the expression of and Bcl-2 was significantly increased(P<0.05).To conclude,croton cream may inhibit the activation of JNK/p38 MAPK signaling pathway and reduce neuronal apoptosis to achieve neuroprotective effects in rats with cerebral ischemia-reperfusion injury.
