Objective To summarize and analyze the clinical features,imaging manifestations,pathological characteristics,treatment approaches,and prognosis of adrenal anastomotic hemangioma(AH),so as to enhance the clinical understanding of this disease.Methods A retrospective analysis was conducted on 3 adrenal AH patients treated in Tongji Hospital during Jan.2012 and Dec.2024.Relevant literature was reviewed.Results All patients were male,aged 34-56 years,with a maximum tumor diameter of 2.0-5.0 cm.All tumors were solitary.No patients presented with special clinical manifestations.Biochemical tests indicated tumors with no endocrine function.Contrast-enhanced computed tomography showed circular mixed density shadows with uneven edge enhancement.Two patients underwent laparoscopic partial adrenal resection,and one patient received robot-assisted laparoscopic partial adrenal resection.Postoperative pathological results of all three cases indicated AH.Immunohistochemistry showed CD31(+),CD34(+),and ERG(+).No recurrence was found in a postoperative follow-up of 1-45 months.A total of 22 cases of adrenal AH were reported in the literature and our center,with onset age ranging from 34 to 83 years.The patients included 17 males and 5 females,with a maximum tumor diameter of 0.6-8.8 cm.Among them,2 cases were multifocal and the tumors were located in the kidneys,beside kidneys,or in the inferior vena cava.Two cases showed clinical manifestations of lower back pain.During the follow-up of 156 months,no recurrence or metastasis was observed.Conclusion Adrenal AH is a rare benign tumor,which mainly occurs in middle-aged and elderly people with no clinical symptoms and endocrine function.Imaging can easily mistake it for pheochromocytoma or well differentiated vascular sarcoma,and the diagnosis mainly relies on pathological examination.It should be distinguished from pheochromocytoma and well differentiated vascular sarcoma.Surgery is the main treatment method and the prognosis is good.

Objective To investigate the effect of closed-chain exercise training on hemiplegic shoulder pain and shoulder joint sta-bility in stroke patients,and to explore the relationship between hemiplegic shoulder pain and shoulder joint sta-bility.Methods A total of 52 stroke patients with hemiplegic shoulder pain in Jiangsu Province Hospital from October,2020 to January,2023 were selected,and were randomly divided into control group(n=26)and experimental group(n=26).Both groups received conventional rehabilitation therapy,while the experimental group additionally under-went closed-chain exercise training for shoulder joint.Pain severity and motor function were assessed using Visu-al Analog Scale(VAS)and Fugl-Meyer Assessment-Upper Extremities(FMA-UE)before and after intervention.Musculoskeletal ultrasound was used to measure acromion-greater tuberosity distance(AGT),acromion-lesser tu-berosity distance(ALT),acromiohumeral distance(AHD)and supraspinatus thickness(SST)to evaluate shoulder joint stability.Correlation analysis was conducted on the improvements in shoulder pain and shoulder joint stabil-ity in the experimental group.Results Two cases in the control group and two in the experimental group dropped down.Both groups showed signifi-cant improvements in VAS and FMA-UE scores after intervention(|t|>5.214,P<0.001),and the scores im-proved more in the experimental group than in the control group(|t|>2.087,P<0.05).The experimental group also showed significant improvements in AGT,ALT,AHD and SST(|t|>4.187,P<0.001),with AGT,ALT and AHD being superior to those in the control group(|t|>2.155,P<0.05).The difference of VAS score in the exper-imental group was correlated with the difference of FMA-UE,AGT and ALT after intervention(r>0.434,P<0.05).Conclusion Closed-chain shoulder exercise training can significantly improve shoulder joint stability while alleviating shoulder pain,and effectively enhancing upper limb function in stroke patients with hemiplegic shoulder pain.Hemiplegic shoulder pain is correlated with shoulder joint stability.

Objectives:To analyze the effect of vertebral or intraspinal abnormalities on the efficacy of pos-terior corrective surgery for scoliosis patients with arthrogryposis multiplex congenita(AMC).Methods:A retro-spective study was conducted on 30 scoliosis patients with AMC who underwent posterior corrective surgery in the Department of Spine Surgery of Drum Tower Hospital between August 2001 and November 2021.There were 18 males and 12 females with a mean age of 15.9±5.8(6-32)years.The patients were divided into ab-normal group(15 cases)and control group(15 cases)according to with or without vertebral or intraspinal ab-normalities.The types of vertebral or intraspinal abnormalities in the abnormal group were recorded,and the number of fusion segments,operative time and intraoperative blood loss were compared between groups.The complications during follow-up were also collected.The flexibility of major curve was assessed on Bending radiographs,and the main curve Cobb angle,the distance between C7 plumb line and center sacral vertical line(C7PL-CSVL),the sagittal vertical axis(SVA),the thoracic kyphosis(TK),and the lumbar lordosis(LL)were measured on the standing whole spine anteroposterior and lateral X-ray images at pre-operation,postoperative two weeks and two years,and the correction rate of major curve was calculated at 2 weeks after surgery and the final follow-up.Results:There were 10 cases of simple poor segmentation(66.6％),2 cases of poor seg-mentation combined with tethered cord(13.3％),and 1 case of poor segmentation combined with arachnoid cyst,simple hemivertebra,and simple wedge-shaped vertebra(6.7％)each in the abnormal group.There were no significant differences between abnormal group and control group in the number of fusion segments,opera-tive time and intraoperative blood loss(P＞0.05).No complication was observed during operation in the abnor-mal group,and 3 complications were observed during follow-up,including 2 cases with screw misplacements and 1 case with thoracic effusion and the right brachial plexus paralysis;5 cases of complications in the control group were observed,including 1 case with malignant hyperthermia and cardiac arrest during the surgery,3 cases with screw misplacements and 1 with thoracic effusion and screw placement failure.The in-cidence of complications was not statistically different between the two groups(P=0.628).The flexibility of ma-jor curve before operation was not statistically different between the two groups(P＞0.05);The major curve Cobb angle,C7PL-CSVL,SVA,TK and LL at pre-operation,post-operative two weeks and 2 months were not statistically different between groups(P＞0.05);The correction rate of major curve at 2 weeks and 2 months after surgery were not significantly different as well(P＞0.05).Conclusions:Vertebral or intraspinal abnormali-ties have no obvious effects on the efficacy of posterior corrective surgery for the treatment of scoliosis pa-tients with AMC,and there is no significant increase in the incidence of intraoperative and postoperative com-plications.

Objective To investigate the clinical features of Brucella meningitis combined with anti-N-methyl-D-aspartate receptor(NMDAR)encephalitis.Methods The clinical data of one patient diagnosed by the Department of Neurology of Nanjing Second Hospital in May 2022 with brucella meningitis combined with anti-NMDAR encephalitis were reported,and its clinical characteristics were summarized and analyzed through literature search.Results The patient was a 33-year-old man with headache,vomiting,weakness in both lower extremities,and fever 1 week later.Brain MRI showed abnormal signals in the deep white matter of the bilateral frontal lobes,and mild enhancement of the basal ganglia and pia mater.CSF suggested an increase in nucleated cells,mainly monocytes,increased protein,and decreased glucose.CSF culture showed Brucella,Brucella IgG antibody(+),Brucellosis tiger red plate agglutination test(+),test tube agglutination test was 1∶25,and temperature decreased after anti-brucella treatment.Patients presented with unresponsiveness,cognitive decline,and speech impairment in the 22nd day of the course of the disease,CSF pathogenic microorganism metagenomic testing suggested Brucella malta,and CSF autoimmune antibodies suggested moderate positivity for antiglutamate receptor(NMDAR type).Symptoms improved with high-dose shock hormone therapy.Conclusions CSF etiology metagenomic testing can improve the diagnosis rate of Brucella meningitis.Brucella may be used as a predisposing factor for anti-NMDAR encephalitis,when the patient's condition is recurrent,and cognitive decline,speech disorders and other symptoms,it is necessary to be alert to the possibility of promoting anti-NMDAR encephalitis,and relevant antibody detection should be improved in time to start immunotherapy as soon as possible.

Objective    To explore the safety, feasibility and superiority of tubeless video-assisted thoracoscopy in the treatment of primary palmar hyperhidrosis (PPH). Methods    The clinical data of 46 patients with palmar hyperhidrosis treated by thoracoscopy in the Department of Thoracic Surgery of the First Hospital of Lanzhou University from March 2017 to September 2020 were retrospectively analyzed. Among them, 22 received tubeless video-assisted thoracoscopic surgery, and were divided into a tubeless group, including 10 males and 12 females with an average age of 24.3±6.4 years; 24 received conventional thoracoscopic surgery, and were divided into a control group, including 13 males and 11 females with an average age of 23.5±4.8 years. The operation status, anesthesia effect and postoperative complications of the two groups were compared. Results    Forty-six patients successfully completed the operation with the assistance of thoracoscopy. There was no intraoperative transfer to thoracotomy, or intraoperative transfer to tracheal intubation in the tubeless group. Anesthetic recovery time (14.4±1.6 min vs. 20.1±1.8 min, P=0.000), time to get out of bed on the first postoperative day (3.1±0.6 h vs. 1.6±0.4 h, P=0.000), visual analogue score for postoperative pain (1.4±0.6 points vs. 3.4±1.1 points, P=0.000), postoperative hospital stay (1.7±0.5 d vs. 2.8±0.6 d, P=0.000), postoperative satisfaction rate of patients (95.5% vs. 66.7%, P=0.037) in the tubeless group were shorter or better than those in the control group. There was no statistical difference in age, gender, smoking history, palmar hyperhidrosis classification, palms or other  associated parts, the total time of bilateral surgery, intraoperative blood loss, postoperative complications, or compensatory hyperhidrosis (mild) between the two groups (P>0.05). Conclusion    Compared with traditional thoracoscopic surgery for PPH, tubeless video-assisted thoracoscopic surgery for PPH has the advantages of safety, reliability, light pain and quick recovery, in line with the concept of accelerated rehabilitation surgery.

Background: Antimicrobial peptides (AMPs) have been identified as promising compounds for consideration as novel antimicrobial agents. Objectives: This study analyzed the efficacy of cecropin B against Haemophilus parasuis isolates through scanning electron microscopy (SEM) and atomic force microscopy (AFM) experiments. Results: Cecropin B exhibited broad inhibition activity against 15 standard Haemophilus parasuis (HPS) strains and 5 of the clinical isolates had minimum inhibition concentrations (MICs) ranging from 2 to 16 μg/mL. Microelectrophoresis and hexadecane adsorption assays indicated that the more hydrophobic and the higher the isoelectric point (IEP) of the strain, the more sensitive it was to cecropin B. Through SEM, multiple blisters of various shapes and dents on the cell surface were observed. Protrusions and leakage were detected by AFM. Conclusions Based on the results, cecropin B could inhibit HPS via a pore-forming mechanism by interacting with the cytoplasmic membrane of bacteria. Moreover, as cecropin B concentration increased, the bacteria membrane was more seriously damaged. Thus, cecropin B could be developed as an effective anti-HPS agent for use in clinical applications.

Objective    To explore the association between preoperative, perioperative parameters, especially estimated glomerular filtration rate (eGFR) and postoperative atrial fibrillation (POAF) after modified extended Morrow procedure. Methods    A total of 300 hypertrophic obstructive cardiomyopathy (HOCM) patients who underwent modified extended Morrow procedure in our hospital from January 2012 to March 2018 were collected. There were 197 (65.67%) males and 103 (34.33%) females with an average age of 43.54±13.81 years. Heart rhythm was continuously monitored during hospitalization. The patients were divided into a POAF group (n=68) and a non-POAF group (n=232). The general data, perioperative parameters and echocardiographic results were collected by consulting medical records for statistical analysis. Univariate and multivariate logistic regression models were used to analyze the risk factors for POAF. Results    Overall incidence of POAF during hospitalization was 22.67% (68/300). Compared with patients without POAF, patients with POAF were older, had higher incidence of chest pain and syncope, lower level of preoperative eGFR, higher body mass index and heart function classification (NYHA), larger preoperative left atrial diameter and left ventricular end diastolic diameter, and longer ventilator-assisted time, ICU stay and postoperative hospital stay. Age, heart function classification (NYHA)≥Ⅲ, hypertension, syncope history and eGFR were independent risk factors for POAF. Receiver operating characteristic curve analysis showed that the area under the curve of eGFR was 0.731 (95%CI 0.677-0.780, P<0.001), and the sensitivity and specificity were 82.4% and 57.8%, respectively. Conclusion    Increased age, high preoperative heart function classification (NYHA), hypertension, preoperative syncope history and decreased eGFR are independent risk factors for POAF in HOCM patients who underwent surgical septal myectomy. Preoperative decreased eGFR can moderately predict the occurrence of POAF after modified extended Morrow procedure.
