At present,radiofrequency ablation(RFA)has already replaced medication therapy and become the first-line treatment option for patients with atrial fibrillation.Intraoperative cardiac tamponade is the most commonly-seen fatal complication,and,unfortunately,the absolute number of this pernicious event is increasing with the extensive use of RFA.Therefore,the full understanding of cardiac tamponade and timely management of cardiac tamponade are of great significance in clinical practice.This article reviews the diagnosis,rescue and treatment process,prognosis and prevention strategies of this complication.(J Intervent Radiol,2024,33:325-329)

Objective : To investigate the epidemiological and clinical characteristics of cases with pertussis in Yiwu City, Zhejiang Province, so as to provide insights into pertussis diagnosis and control. Methods: A total of 186 patients with definitive diagnosis of pertussis in medical institutions in Yiwu City from November 1, 2020 to August 31, 2022 were recruited, and subjects' demographic, clinical symptoms and history of pertussis vaccination were collected using questionnaire surveys. The temporal, population, and spatial distribution and clinical symptoms of pertussis were analyzed using a descriptive epidemiological method, and the clinical characteristics of pertussis patients with different doses of pertussis vaccination were compared. Results: Pertussis was found to predominantly occur during the period between July and November (101 cases, 54.30%), and the three highest-incidence regions included Jiangdong Street, Beiyuan Street and Choujiang Street (87 cases, 46.77%). The 186 pertussis cases included 105 males (56.45%) and 81 females (43.55%), and included 144 cases with age of onset under 7 year (77.42%). Preschool and diaspora children were predominant among all pertussis cases, and the main clinical symptoms included spasmodic cough (97 cases, 52.15%), post-tussive vomiting (82 cases, 44.09%) and aggravated cough at night (77 cases, 41.40%). Routine blood tests measured 119 cases with abnormal white blood cell counts (63.98%), 137 cases with abnormal lymphocyte counts (73.66%), 39 cases with abnormal neutrophil counts (20.97%), 21 cases with abnormal platelet counts (11.29%) and 111 cases with abnormal hemoglobin concentrations (59.68%). There were 55 cases that were unvaccinated (29.57%), 23 cases that were not fully vaccinated (12.37%), and 108 cases that were fully vaccinated (58.06%). There were significant differences among pertussis cases with different doses of vaccination in terms of age, incidence of post-tussive vomiting, percentage of abnormal platelet counts and percentage of hemoglobin concentrations (all P<0.05). Conclusions The majority of pertussis cases are preschool and diaspora children in Yiwu City from November 1, 2020 to August 31, 2022, and the clinical symptoms mainly include spasmodic cough, post-tussive vomiting and aggravated cough at night, with atypical symptoms. The capability for differential diagnosis of pertussis is required to be improved in medical institutions.

To analyze the clinical characteristics and genetic data of a child with type Ⅱ Bruce syndrome (type Ⅱ BS) admitted to the Department of Orthopedics, Shanxi Children′s Hospital at May 2020.A 3-day-old boy was admitted due to the pain and swelling of the right lower limb 3 days after birth.Due to the patient had multiple fractures, callus formation after clavicle and rib fracture, greendstick fracture of the humerus, right femur fracture, left tibia and fibula fracture, congenital clubfoot, and congenital contracture of wrist, elbow, hip and knee joint, and therefore, chromosome diseases were considered.Gene sequencing data showed gene mutation in PLOD2 with compound heterozygosity deletion of the child (proband), and mutation and heterozygosity deletion came from their parents, respectively.The patient was diagnosed as type Ⅱ BS.This case report alarms clinicians to identify a missense mutation of PLOD2 and loss of heterozygosity, so as to reduce the misdiagnosis rate and achieve early diagnosis and treatment.

Objective:To investigate the clinical effect of minimally invasive treatment of supracondylar fracture of humerus with nerve injury and the need for surgical exploration of nerve.Methods:From August 2017 to September 2020, 34 cases of children with supracondylar fracture of humerus with nerve injury in the Department of orthopedics of Shanxi Children′s Hospital were selected for retrospective analysis.Closed reduction, Kirschner wire fixation and small incision surgery were used to explore the injured nerve.The follow-up period ranged from 6 months to 3 years, with a follow-up time of (2.15±0.49) years.The elbow function, radial nerve, median nerve and ulnar nerve function were evaluated according to the trial standard of upper limb peripheral nerve function evaluation of Hand Surgery Society of Chinese Medical Association.Results:The elbow function of children in this group: excellent 31 cases, good 2 cases, fair 1 cases, poor 0 cases, excellent 33 cases.Three patients failed to take early functional rehabilitation exercise.Two patients recovered after 2.5 months of treatment by professional orthopedic rehabilitation therapists and physical therapy.One of them did not cooperate with functional rehabilitation training.After 3.5 months of treatment by orthopedic rehabilitation therapists, elbow and finger functions were not affected.Two weeks after nerve injury: radial nerve function evaluation: excellent in 15 cases, good in 3 cases, fair in 4 cases, poor in 0 cases, excellent in 18 cases.Median nerve function evaluation: excellent in 5 cases, good in 2 cases, fair in 6 cases, poor in 0 cases, excellent in 7 cases.Ulnar nerve function evaluation: excellent 5 cases, good 0 cases, fair 1 cases, poor 0 cases, excellent 5 cases.At 3 months after injury, the excellent and good rate of radial nerve, median nerve and ulnar nerve was 100%.Conclusion:The supracondylar fracture of humerus with nerve injury is treated by minimally invasive surgery, and the nerve exploration is still a few.The recovery of nerve injury after surgery is smooth, and the clinical effect is good.

Objective:To investigate the characteristics of attentional bias in adolescents with anxiety disorder.Methods:Totally 40 adolescents with anxiety disorder who met the DSM-5 diagnostic criteria were recruited as the case group, 40 normal adolescents matched with the case group in terms of gender, age and education level were served as the control group.Symptom was assessed by the screen for child anxiety related emotional disorders (SCARED), and attention bias was assessed by attention bias test on both groups.All data were analyzed using SPSS 21.0.Results:(1) In the test of attentional bias, the negative reaction of the case group was lower than the neutral response((647.14±94.44)ms, (661.08±112.07)ms), and the attention bias value of the case group was higher than the control group((13.93±33.27)ms, (-0.13±18.49)ms), the differences were statistically significant (both P<0.05). (2) In the total score and each factor score of SCARED, total score of SCARED was negatively correlated with the negative accuracy rate ( r=-0.38), and the separation anxiety score was negatively correlated with the negative accuracy rate ( r=-0.52), social terrorism scores were negatively correlated with negative accuracy ( r=-0.45) and neutral accuracy ( r=-0.43) (all P<0.05). The correlation between somatization, generalized anxiety and school terror with attention bias test were not significant( P>0.05). Conclusion:Adolescents with anxiety disorder are more concerned with negative stimuli, and it is difficult to shift attention from negative stimuli to others.The avoidance to neutral stimuli may be a risk factor for the severity of symptoms in adolescents with anxiety disorders.

Objective To evaluate the mid-term and long-term effects of early endovascular emboli-zation in treating ruptured posterior communicating artery aneurysm. Methods Early endovascular embolization therapy was carried out in 36 patients with ruptured posterior communicating artery aneurysm (36 aneurysms in total), and the effects of embolization therapy were evaluated by using Raymond grading method. The unified imaging review program was formulated, and the mid-term and long-term effects were evaluated at half, 1, 2, 3 and 5 years after the treatment. Results The technical success rate was 100% in 36 patients (36 aneurysms in total). Raymond grading evaluation showed that gradeⅠwas seen in 32 patients, gradeⅡ in 2 patients, and grade Ⅲ in 2 patients. Recurrence of aneurysm was found in 5 patients (13.89%) at half (n=1), 2 (n=1), 3 (n=1) and 5 years (n=2) after the treatment. Re-rupture of the recurrent aneurysm was seen in one patient (2.78%). No death occurred during the following-up period. Conclusion Early endovascular embolization for ruptured posterior communicating artery aneurysm can effectively improve the prognosis of subarachnoid hemorrhage, and regular imaging examination can promptly detect the recurrence of aneurysm. Effective interventions are helpful for preventing deterioration and rupture of aneurysm.

Impaired clearance of apoptotic cells is important in the pathogenesis of autoimmune disease.C-reactive protein (CRP) is an acute phase protein that plays a major role in the regulation of the autoimmune and inflammatory response .CRP has a role in the clearance of bacteria and dying and altered cells through binding to phosphocholine and might also have more complex immunomodulatory functions . CRP function as opsonins for pathogens and dying and apoptotic cells through activation of the complement pathway and through binding to Fcγreceptors , and is associated with the clearance of apoptotic cells and nuclear antigen , thus becoming a protective molecule against pathogenic autoimmune responses in general . Measurement of serum CRP level is in widespread clinical use as a sensitive marker of inflammation and autoimmune disease , particularly in relation to the use of the CRP-based disease activity score in the evaluation of rheumatoid disease.
