Coronary artery fistula(CAF)is defined as the direct connection between coronary artery and cardiac cavity,great vessel or other vascular structures.Most CAF are congenital and often present as persistent murmur in asymptomatic children.Although abnormal shunt of most coronary fistulas has little effect on hemodynamics,some larger fistulas can also lead to a series of complications,such as congestive heart failure.Therefore,closed CAF has been recommended to treat or prevent myocardial ischemia,congestive heart failure,endarteritis,arrhythmia,thromboembolism,aneurysm dilatation and rupture and other complications.CAF is a rare congenital heart disease,and bilateral CAF originating from two coronary arteries is even rarer.At present,there are rare systematic reports on bilateral CAF.Therefore,a case of huge bilateral CAF at the same site was reported,and systematically,this kind of case was summarized,so as to improve the clinical attention of diagnosis and treatment of this kind of CAF.Nowadays,some new interventional devices and technologies are emerging with the continuous progress of cardiovascular interventional technology,making the treatment more accurate,safe and effective.At the same time,there is also a clearer understanding of the indications and operating standards for interventional treatment,which is more operable and predictable during the treatment process.Therefore,interventional treatment of CAF may partially replace surgical treatment as the preferred treatment method.

This study was aimed at exploring the epidemiological characteristics of plague,and the evolutionary relation-ships among the isolated plague strains in the Yunnan border area,to provide clues for further studying epidemic causes and ep-idemiological patterns.Plague epidemic data in the border area during the second epidemic period(1982-2007)were collected and analyzed with descriptive epidemiological methods.Whole genome sequences of 262 strains of Yersinia pestis in the border area were obtained for phylogenetic analysis.Plague outbreaks occurred in 17 counties(cities)among 25 border counties(cit-ies);a total of 552 epidemic foci and 123 human cases were identified.The 1.ORI2,1.ORI3,1.IN3,2.ANT and 2.MED geno-types were identified among Yersinia pestis isolated from the Yunnan border area,among which the 1.ORI2 population was dominant.A total of 258 strains of Yersinia pestis from the 1.OR12 population belonged to four subclusters.The Myanmar and Vietnam clade was embedded within the Yunnan clade in the overall phylogeny.The above results indicated that during the sec-ond period of the epidemic,the intensity of plague epidemics in Yunnan's border areas was high,showing a trend of devel-opment from west to south and east.Our findings indicated a risk of cross-border transmission of plague between Yunnan and neighboring countries;therefore,the surveillance,pre-vention,and control of plague in border areas should be strengthened.

Objective:To analyze the prognostic value of del(1p32)in patients with newly diagnosed multiple myeloma(MM).Methods:The clinical data of 341 newly diagnosed MM attended in Jiangsu Province Hospital were retrospective analyzed.Clinical characteristic combined with genetic features,especially del(1p32),were analyzed for survival and prognostic of patients.Results:Among the 341 patients with newly diagnosed MM,24(7.0％)patients were del(1p32)positive.The progression-free survival(PFS)and overall survival(OS)were significantly shorter in MM patients with del(1p3 2)than those without de1(1p32)(PFS:P＜0.001;OS:P＜0.001).The COX proportional-hazards model showed that del(1 p32)was an independent risk factor for PFS and OS of patients with MM.The patients with both 1q21 gain/amplification and del(1p32),as"double-hit chromosome 1",have worse prognosis than those with only 1q21 gain/amplification or only del(1 p32)(PFS:P＜0.001;OS:P＜0.001).Conclusion:Del(1p32)is an independent risk factor for PFS and OS of patients with MM.Del(1p32)detection should be widely used in the prognostic analysis for newly diagnosed MM patients.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.

Objective To investigate the incidence and risk factors for acute kidney injury(AKI)in children with primary nephrotic syndrome(PNS),as well as the role of neutrophil gelatinase-associated lipocalin(NGAL)and kidney injury molecule-1(KIM-1)in the early identification of AKI in these children.Methods A prospective collection of clinical data from children hospitalized with PNS at the Children's Hospital of the Capital Institute of Pediatrics from January 2021 to October 2022 was conducted.The children were divided into two groups based on the presence of AKI:the AKI group(47 cases)and the non-AKI group(169 cases).The risk factors for AKI in children with PNS were identified by multivariate logistic regression analysis.Urinary KIM-1 and NGAL levels were compared between the AKI and non-AKI groups,as well as among the different stages of AKI.Results The incidence of AKI in children with PNS was 21.8%.Multivariate logistic regression analysis revealed that steroid-resistant nephrotic syndrome,gastrointestinal infections,and heavy proteinuria were independent risk factors for AKI in these children with PNS(P<0.05).Urinary KIM-1 and NGAL levels were higher in the AKI group compared to the non-AKI group(P<0.05),and the urinary NGAL and KIM-1 levels in the AKI stage 2 and stage 3 subgroups were higher than those in the AKI stage 1 subgroup(P<0.017).Conclusions KIM-1 and NGAL can serve as biomarkers for the early diagnosis of AKI in children with PNS.Identifying high-risk populations for AKI in children with PNS and strengthening the monitoring of related risk factors is of significant importance.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective To explore the diagnosis and clinical characteristics of atypical severe pneumonia caused by Chlamydia abortus(C.abortus).Methods Clinical data of 4 patients diagnosed with atypical severe pneumonia caused by C.abortus in a hospital from January 2021 to November 2022 were collected.Clinical characteristics,dia-gnosis and treatment,and precautions of the disease were comprehensively analyzed.Results All 4 patients were male,aged 63-73 years old,with acute onset,high fever,cough and expectoration.Three patients had a history of contact with poultry,one patient had a history of contact with abortion goat.The interval between the emerging of clinical symptoms and the onset of acute respiratory failure in 4 patients was 1-6 days,and the oxygenation index(PaO2/FiO2)at admission was less than 200 mmHg,which gradually decreased with the progression of the disease,active support with a ventilator was necessary.Two patients had an increase in white blood cell count,4 had an in-crease in neutrophil percentage,3 had a mild decrease in platelet count.Among 4 patients,2,2,3 and 4 patients showed elevated levels of aspartate aminotransferase,alanine aminotransferase,creatine kinase,and serum creati-nine respectively,2 patients had mild hyponatremia,4 patients showed significant increase in C-reactive protein,procalcitonin,and interleukin-6 levels.Four patients'chest CT findings showed main involvement of single or mul-tiple lung lobes,with exudation and consolidation,and later involvement of multiple lobes of lung.The metageno-mic next-generation sequencing of bronchoalveolar lavage fluid detected the DNA sequence of C.abortus.Based on the clinical manifestations,contact history,chest CT,and metagenomic next-generation sequencing results of 4 pa-tients,the diagnosis was C.abortus.atypical severe pneumonia.After timely adjustment of the treatment of anti-in-fection regimen based on doxycycline,the patients'condition improved and were discharged.Conclusion C.abor-tus may also cause human pneumonia,which can lead to serious clinical outcome after infection.Patient had a histo-ry of animal contact should be alert to such diseases.Metagenomic next-generation sequencing can detect C.abortus.

Ankylosing spondylitis (AS) combined with lower cervical fracture is often categorized into unstable fracture, with a high incidence of neurological injury and a high rate of disability and morbidity. As factors such as shoulder occlusion may affect the accuracy of X-ray imaging diagnosis, it is often easily misdiagnosed at the primary diagnosis. Non-operative treatment has complications such as bone nonunion and the possibility of secondary neurological damage, while the timing, access and choice of surgical treatment are still controversial. Currently, there are no clinical practice guidelines for the treatment of AS combined with lower cervical fracture with or without dislocation. To this end, the Spinal Trauma Group of Orthopedics Branch of Chinese Medical Doctor Association organized experts to formulate Clinical guidelines for the treatment of ankylosing spondylitis combined with lower cervical fracture in adults ( version 2024) in accordance with the principles of evidence-based medicine, scientificity and practicality, in which 11 recommendations were put forward in terms of the diagnosis, imaging evaluation, typing and treatment, etc, to provide guidance for the diagnosis and treatment of AS combined with lower cervical fracture.

Objective To investigate the therapeutic effect of cnithol on acute pancreatitis(AP)rats and its regulatory mechanism on phosphoinositol 3-kinase(PI3K)/protein kinase B(Akt)signaling pathway.Methods SPF-grade SD male rats were randomly divided into control group,model group(50 μg·kg-1 hyranin+10 mg·kg-1 LPS),positive control group(2 mg·kg-1 dexamethasone),experimental-L group(20 mg·kg-1 osthol)and experimental-H group(40 mg·kg-1 osthol),experimental-H+740Y-P group(40 mg·kg-1 osthol+2 mg·kg-1 PI3K activator 740Y-P),15 mice in each group.The activities of amylase and lipase in serum of rats were detected by automatic biochemical analyzer 24 h after the last administration.The levels of inflammatory factors tumor necrosis factor-α(TNF-α)and interleukin-6(IL-6)in serum,the content of malondialdehyde(MDA)and the activity of superoxide dismutase(SOD)in pancreas were detected by enzyme-linked immunosorbent assay(ELISA).Hematoxylin-eosin(HE)staining was used to observe the pathological changes of pancreatic tissue and score the pathological damage.Western blot was used to detect the expression of PI3K/Akt pathway related proteins in rat pancreas.Results The activities of serum amylase in control group,model group,positive control group,experimental-H group and experimental-H+740Y-P group were(135.67±12.89),(1 027.84±32.16),(174.31±15.27),(186.70±17.39)and(835.92±28.78)U·mL-1,respectively;the contents of TNF-α were(35.69±3.10),(223.54±15.23),(48.76±4.25),(52.31±4.68)and(208.46±13.65)pg·mL-1,respectively;the contents of MDA were(2.15±0.14),(6.37±0.42),(2.78±0.17),(2.81±0.15)and(5.96±0.36)nmol·mg-1,respectively;the histopathological injury scores were 1.12±0.07,10.23±0.38,3.14±0.21,3.25±0.23 and 9.68±0.40,respectively;p-PI3K/PI3K ratios were 0.82±0.05,1.96±0.15,1.07±0.06,1.10±0.07 and 1.69±0.14,respectively.The above indexes were compared with the control group in the model group,the positive control group,experimental-H group and the model group,and the above indexes of experimental-H+740Y-P group and experimental-H group,and the differences were statistically significant(all P＜0.05).Conclusion Gossetin can play a therapeutic role in AP,and its mechanism may be related to the inhibition of PI3K/Akt signaling pathway.

Objective To explore the effect of Shexiang Baoxin pill on cardiac tissue angiogenesis in spontaneously hypertensive rats(SHR).Method Twenty 12 week old male SHR were randomly divided into experimental group and model group,with 12 week old male SD rats as the normal control group.The experimental group rats were orally administered with Shexiang Baoxin pill(45 mg·kg-1)daily,and their blood pressure was monitored using a non-invasive tail artery blood pressure gauge every four weeks.Eight weeks later,cardiac tissue was taken for platelet endothelial cell adhesion molecule-1(PECAM-1/CD31)immunofluorescence staining to observe CD31 expression level.Use protein blotting to detect the expression levels of myocardial endothelial growth factor(VEGF),myocardial endothelial growth factor receptor 2(VEGF-R2),basic fibroblast growth factor(bFGF)and phosphorylated protein kinase B(p-Akt)/protein kinase B(Akt)proteins.Result There was significant increase in blood pressure between the experimental group,model group and normal group at the same time point(all P＜0.01),but there was no statistically significant difference in blood pressure changes between the experimental group and model group at the same time point(all P＞0.05).The CD31 expression rates of the normal group,model group and experimental group were(3.79±0.84)％,(2.54±0.42)％and(3.56±0.49)％;VEGF levels were 0.95±0.10,0.73±0.08 and 0.94±0.15;VEGF-R2 levels were 0.85±0.10,0.61±0.14 and 0.80±0.10;bFGF levels were 0.84±0.04,0.51±0.21 and 0.74±0.14;p-Akt/Akt levels were 0.85±0.15,0.57±0.13 and 0.80±0.20,respectively.The differences between the normal group and the model group,as well as the experimental group and the model group,were statistically significant(all P＜0.05).Conclusion Shexiang Baoxin pill can promote the neovascularization of microvessels in the heart tissue of spontaneously hypertensive rats,and its mechanism may be related to the activation of PI3K/Akt phosphorylation,upregulation of bFGF,VEGF and their receptor VEGF-R2 in myocardial tissue.
