To investigate the efficacy and safety of glucocorticoids combined with cyclophosphamide (CTX) and rituximab (RTX) in elderly patients with anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis with renal involvement.

With the continuous advancement of neuroimaging technologies, clinical research has discovered the phenomenon of cognitive-motor dissociation in patients with disorders of consciousness (DoC). This groundbreaking finding has provided new impetus for the development and application of brain-computer interface (BCI) in clinic. Currently, BCI has been widely applied in DoC patients as an important tool for assessing and assisting behaviorally unresponsive individuals. This paper reviews the current applications of BCI in DoC patients, focusing four main aspects including consciousness detection, auxiliary diagnosis, prognosis assessment, and rehabilitation treatment. It also provides an in-depth analysis of representative key techniques and experimental outcomes in each aspect, which include BCI paradigm designs, brain signal decoding method, and feedback mechanisms. Furthermore, the paper offers recommendations for BCI design tailored to DoC patients and discusses future directions for research and clinical practice in this field.

Objective To explore the impact of"knowledge-attitude-practice"(KAP)training mode on head nur-ses' core competency in healthcare-associated infection(HAI)prevention and control in a tertiary first-class general hospital.Methods Head nurses of 113 departments in a tertiary first-class general hospital were taken as the re-search objects.Guided by problems and demands,HAI training was conducted using the KAP training mode.The training was divided into two stages:a stage with problems of infection control and investigation of knowledge de-mands,as well as a stage with KAP training mode implementation.It included theoretical lectures,visits and lear-ning,and supervision on rectification.Scores of theory,supervision,and core competency of head nurses before training,1 month and 6 months after training were compared by the analysis of variance.SPSS 26.0 statistical soft-ware was used for analysis.Results The top three infection control problems in this hospital were hand hygiene,prevention and control of infection with multidrug-resistant organisms,as well as HAI prevention and control in the wards.The top three training modules required urgently by the head nurses were occupational exposure and self-protection,principles of medical waste disposal,as well as prevention and control of HAI in the wards.Both scores of theory and supervision after training were higher than those before training,with statistically significant diffe-rences(both P＜0.01).The core competencies of the head nurses were at a high level.After implementing KAP training mode,the scores of dimensions in critical thought and research,clinical nursing,leadership,and profe-ssional development,as well as the overall score of core competencies were all higher than before training.Diffe-rences were all statistically significant(all P＜0.05).The overall scores of dimensions in legal and ethical practice,education and consultation,as well as interpersonal relationship were all higher than before training,but the diffe-rences were not statistically significant(all P＞0.05).Conclusion KAP training mode can significantly improve the scores of theory,supervision,and core competencies of head nurses,and can be further promoted and applied in head nurses' infection control training.

A 32-year-old female patient experienced a foreign body sensation in her esophagus on the evening of September 22, 2024, after consuming undercooked grass carp at a restaurant in Wuhan. Esophagoscopy conducted at the hospital revealed no abnormalities. Three days later, she had a stabbing pain in the pharynx. On October 8, upon self-examination, she noticed a red brown worm exhibiting stretching and contracting movements attached near the uvula in her pharynx and then went to the hospital. During the removal of the worm, the doctor observed the ulcers on the mucous membrane. Serological antibody tests for seven common human parasitic worms, including Schistosoma japonicum, Paragonimus westermani, Clonorchis sinensis, cysticercus of Taenia solium, sparganum, hydatid cyst, and Trichinella spiralis, were all negative. The isolated worm was reddish brown, measuring 4 mm in length and 2 mm in width. Staining with hydrochloric carmine dye revealed a morphology consistent with Clinostomum complanatum (Rud., 1819), characterized by an oral sucker at the anterior end, a pharynx connecting to intestinal branches, and two intestinal branches extending to the posterior end of the body with small sub-branches. The ventral sucker, larger than the oral sucker, was located at the front 1/4 of the body. A pair of testes were arranged longitudinally in the mid-posterior part, with an ovary located between the two testes and a uterus located above the upper testis. A comprehensive search of 188 databases comprising more than 460 million full-text articles through the library of Huazhong University of Science and Technology confirmed the first reported case of Clinostomum complanatum infection in humans in China.

Objective To explore the clinical efficacy of superselective arterial embolization in children with Parkes-Weber syndrome(PWS),and the prevention and treatment of postoperative complications.Methods Nine patients with PWS diagnosed by clinical and imaging examinations were selected.Under general anesthesia,the catheter was cannulated to all levels of branch arteries and lesion sites using the Seldinger technique.Absorbent gelatin sponge particle(or lipiodol)was selected according to the angiographic situation,and then target vessel embolization was performed.Patients with venous malformations were treated with local sclerotherapy at the same time.The patients were followed up for 1 month,3 months,6 months and 1 year after the operation to observe the clinical efficacy and complication.Results All 9 patients were successfully treated with interventional therapy.Arteriography showed that micro arteriovenous fistula existed at the distal end of multiple branch arteries,and the arteriovenous fistula had been closed after embolization.Review after 1 month of interventional therapy,the color spot of the affected limb became lighter,the temperature decreased,the leg circumference decreased,and the pain was relieved of all 9 cases.Three patients had skin deep color 2-3 days after the operation,so they were given hirudoid local smear,3 times/day,local warm water wet compress,raised limb position,local massage and other methods,and the local skin color gradually recovered after 1 week;On the 15th day after the operation,2 patients suffered from ischemic necrosis at the embolic site,skin color deepened,and tenderness.They were locally disinfected with hirudoid,aurantium peptide,normal saline,and iodophor.The skin broke and scabbed more than 1 month after the operation,the skin ulcer improved and new granulation tissue grew up 1.5 months after the operation;One case had no obvious reduction of the lesion 1 month after the operation,so the second intervention was performed.Conclusion Superselective arterial embolization is effective in the treatment of PWS in children,but the prevention of complications should be paid attention to and complications should be timely treated.

Objective:To understand the infection status, epidemiological characteristics and drug resistance of Diarrheagenic Escherichia coli (DEC) in Shanghai and provide evidence for the disease surveillance. Methods:The epidemiological data of diarrhea cases in Shanghai from 2016 to 2022 were collected from Shanghai Diarrhea Comprehensive Surveillance System, and stool samples were collected from the cases for DEC detection. The drug resistance data was obtained from Chinese Pathogen Identification Network. Statistical analysis was conducted by using χ2 and fisher test. Results:In 24 883 diarrhea cases detected during 2016-2022, the DEC positive rate was 9.13% (2 271/24 883), the single DEC positive rate was 8.83% (2 197/24 883) and the mixed DEC positive rate was 0.30% (74/24 883). The main type of DEC was Enterotoxigenic Escherichia coli (ETEC) [4.33% (1 077/24 883)]. The DEC positive rate was highest in people aged ≤5 years 18.48% (22/119). The annual peak of DEC positive rate was observed during July - September [5.91% (1 470/24 883)]. The DEC positive rate were 9.47% (554/5 847) and 9.02% (1 717/19 036) in urban area and in suburbs, respectively, Enteroaggregative Escherichia coli (EAEC) [3.98% (233/5 847)] and ETEC [4.56% (868/19 036)] were mainly detected. From 2016 to 2019, the DEC positive rate was 9.42% (1 821/19 330), while it was 8.10% (450/5 553) from 2020 to 2022, the main DEC types were ETEC (4.87%, 941/19 330) and EAEC (4.70%, 261/5 553). The multi-drug resistance rate was 40.21% (618/1 537). The top three antibiotics with high drug resistance rates were ampicillin [64.74% (995/1 537)], nalidixic acid [58.49% (899/1 537)] and tetracycline [45.09% (693/1 537)]. Conclusions:Compared with 2016- 2019, a decrease in DEC detection rate was observed during 2020-2022, and the main type of DEC detected shifted from ETEC to EAEC. The prevalence of multi-drug resistance was severe. Therefore, it is necessary to further strengthen the surveillance for DEC drug resistance and standardize the use of clinical antibiotics.

Objective:To explore the optimal index of rotational displacement of femoral neck fractures by modeling the axial rotational displacement of femoral neck fractures after reduction and based on X-ray projections.Methods:Six dry human femur specimens, comprising 2 males and 4 females, were utilized in the study. Design and manufacture a proximal femur ortholateral and oblique X-ray casting jigs and mounts. The femoral neck fracture was modeled on the femoral specimen, with Pauwells 30°, 50°, and 70° models (2 each) made according to Pauwells typing. The fractures were manually repositioned with residual anterior 20°, 40° and 60° axial rotational displacements. Each fracture model was projected at different angles (pedicled 40°, pedicled 20°, vertical 0°, cephalad 20°, and cephalad 40°), and the trabecular angle and Garden's alignment index of the model were measured to observe the imaging characteristics of the fracture line on the medial oblique and lateral oblique radiographs.Results:In the presence of a 20° and 40° anterior rotational displacement following reduction of a femoral neck fracture, the trabecular angle in the rotationally displaced group was not significantly different from that of the anatomically repositioned group in various projection positions. However, when a residual rotational displacement of 60° was present, the trabeculae appeared blurred at most projection angles in the Pauwells 30° and 50° models, failing to measure trabecular angles. In the Pauwells 70° fracture model, the trabecular angle in the rotational displacement group was significantly different from that in the anatomical reduction group. In anteroposterior radiographs, when the anterior rotation displacement was 60° in the Pauwells 70° group, Garden's contralateral index showed an unsatisfactory restoration (150°, 142°), whereas all rotationally displaced models in the Pauwells 30° and Pauwells 50° groups had a Garden's contralateral index of >155°, which achieved an acceptable restoration. In lateral radiographs, all rotational displacement models with Garden's alignment index>180° failed to achieve acceptable repositioning, and the larger the Pauwells angle the greater the Garden's alignment index at the same rotational displacement. In the internal oblique position with a bias towards the foot side, the image showed partial overlap between the femoral head and the shaft, making it difficult to assess the quality of the reduction. Conversely, when projected cephalad, the femoral neck appeared longer, particularly at a projection angle of 40° cephalad, allowing for clear observation of the fracture line and the anatomy of the proximal femur. The trabeculae were not well visualized in the external oblique position.Conclusion:There are limitations in applying the trabecular angle to assess the axial rotational displacement of the femoral head after reduction of femoral neck fractures. The Pauwells 70° with residual rotational anterior displacement of 60° was the only way to detect axial rotational displacement of the femoral head on anteroposterior radiographs Garden's alignment index. For the determination of axial rotational displacement of the femoral head, the Garden's alignment index on lateral radiographs provides higher reliability.

Objective:To explore the reliability and validity of the International Classification of Functioning, Disability and Health′s 17-item Rehabilitation Set (ICF-RS-17) when used to evaluate multidisciplinary inpatients.Methods:A total of 359 inpatients in the departments of rehabilitation, orthopedics, neurology, and neurosurgery of three hospitals in Jiangsu province were assessed with the ICF-RS-17 at admission and at discharge, and the internal consistency of the tool was calculated. Inter-rater and intra-rater reliability were quantified using interclass correlation coefficients (ICCs). Structural validity was analyzed using factor analysis.Results:The tool′s Cronbach′s α was 0.945. The overall inter-rater ICC was 0.946 with the ICCs of all of the items except b280 sensation of pain within the range from 0.630 to 0.948. The overall intra-rater ICCs ranged from 0.471 to 0.947. The factor analysis found three factors with eigenvalues greater than 1, accounting for 74% of the variation, without double-loaded items. The three influential factors were exercise ability, sleep perception communication ability and self-care ability.Conclusion:The ICF-RS-17 has good internal consistency, inter-rater and intra-rater reliability and structural validity in the evaluation of multidisciplinary inpatients.
