ABSTRACT

To analyze simulated patient studies and their developmental trajectory, a comprehensive review was conducted using VOS viewer software. PubMed and CNKI databases were searched for 4 164 articles related to simulated patients. By creating keyword clouds and comparison tables, the current status and development trends of simulated patient studies at home and abroad were analyzed, and visual analysis was conducted based on these findings. Additionally, the analysis encompassed various metrics such as the number of published articles, journals, authors, and institutions involved. The findings reveal that the simulated patient studies focus on education, examination, and communication. Chinese studies on simulated patients initially demonstrated an upward trend but followed with a decline, whereas English studies have exhibited a steady upward trajectory. The application of simulated patients spans diverse fields including diagnostics, internal medicine, surgery, and medical practitioner exams, thereby greatly contributing to the advancement of medical education. It is anticipated that the number of simulated patient studies will continue to surge in the upcoming years.

ABSTRACT

Objective:To explore the application value of preoperative multimodal image fusion 3D reconstruction technology in brain tumor surgery.Methods:The preoperative cranial CT and MR imaging data of 46 patients with brain tumors admitted to our hospital from October 2019 to September 2020 were collected. The image registration and fusion of above imaging data were performed by AW workstation software (GE company), and 3D reconstruction was performed to construct 3D digital anatomic image of brain tumor and its surrounding anatomic structure. Based on this, the surgical approach and surgical plan were designed, and its application value was evaluated by consistency grading.Results:The reconstructed 3D digital anatomical image could clearly show the size, location, shape of the tumors and the anatomical relationships between the tumors and surrounding structures, which was consistent with the original image before and during the surgery. Among the 46 patients, 43 were completely resected and 3 were partially resected. There were no approach-related complications after surgery. The application value of preoperative 3D image fusion was evaluated as 36 with outstanding value, 8 with value, and 2 without value.Conclusion:Preoperative multimodal image fusion 3D reconstruction technology can provide a large amount of visual information during brain tumor surgery, guide the choice of surgical approach and precise resection of tumors.

ABSTRACT

Objective To evaluate the clinical application of regulating bone removal ratio in dual-energy cerebral subtraction angiography.Methods A total of 45 patients who underwent two phases dual-energy CT angiography (CTA) were recruited and divided into several groups by the value of bone removal ratio,as follows: group A (Ratio=1.6), group B (Ratio=1.7), group C (Ratio=1.8) and group D (Ratio=1.9,default), as well as group E (100kV Neuro-DSA).The image quality of dual-energy CTA was evaluated by double blind method according to bone suppression and integrity of the vessel lumen (1-5 points, 1=poor, 5=excellent, 3-5=satisfactory).The bone removal ratio dependence of the image quality was analyzed using the self-control method.Moreover,the signal-to-noise ratio (SNR),contrast-to-noise ratio (CNR) and image scores were compared with the Neuro-DSA subtraction among these groups.Results The overall satisfaction of basis cranii images that were executed by dual-energy CTA with different bone removal ratios was listed as below: group A 73.33%, group B 91.11%, group C 78.52%, group D 70.37%.The satisfaction of siphon segment and petrous segment reached the maximum when the value of ratio was 1.7,and with significantly difference (P0.05).Conclusion With optimal bone removal ratio,the single enhanced dual-energy subtraction image quality with flash dual-source CT is consistent well with that of conventional 100 kV Neuro-DSA subtraction.Thus,this method is recommended in clinical emergency cerebrovascular examination for the improved image quality,which can compensate the shortage of vascular defect in basis cranill.

ABSTRACT

Objective:To explore and assess the clinical application and clinical value of dual helical CT and magnetic resonance imaging (MRI) in the diagnosis of knee bone tumor. Methods: Sixty-nine patients with knee bone tumors were randomly divided into three groups: group A, group B and group C. Group A was detected by double-helical CT scanning; group B was detected by MRI; group C was detected by dual-helical CT scan combined with MRI. After the end of the testing, the clinical diagnostic results of the three detection methods were compared.Results: There was no significant difference between group A and B (x2=0.825,P>0.05). The detection rate of group C was higher than that of group A. The differences were statistically significant (x2=2.936,x2=3.718;P<0.05). The detection rate of group C was significantly higher than that of group B. The differences were statistically significant (x2=3.967,x2=4.285;P<0.05).Conclusion: Double helical CT combined with MRI can effectively improve the clinical detection rate of knee bone tumor.

ABSTRACT

Objective To observe the clinical efficacy and reverse reactions of acupuncture combined with paroxetine hydrochloride in the treatment of mild or moderate depression. Methods The patients with mild or moderate depression (n=73) were randomly divided into control group (treated with paroxetine hydrochloride,n=33) and observation group (treated with acupuncture and paroxetine hydrochloride,n=40). The therapeutic course lasted for 6 weeks. The total score changes of Hamilton Depression Scale (HAMD) were observed before treatment and treated for 1, 2, 4 and 6 weeks. Rating Scale for Side Effects (SERS) was evaluated before treatment and treated for 2, 4, 6 weeks.Results The total effective rate of clinical efficacy in the observation group was 78.95% (30/38) and the control group was 68.75% (22/32), without significant difference between the two groups (P>0.05). The scores of HAMD decreased 4, 6 weeks after the treatment in the control group and 2, 4, 6 week after the treatment in the observation group compared with those in the same group before the treatment (P<0.05,P<0.01). There was a significant difference in HAMD scores between two groups after the treatment for 4 weeks (P<0.05). The scores of SERS showed a significant difference 4, 6 weeks after the treatment between the two groups (P<0.05).Conclusion Acupuncture can improve the curative effect of paroxetine hydrochloride and decrease its side effects in the treatment of depression.

ABSTRACT

Objective To evaluate the long-term curative effect of bronchial artery embolization on massive hemoptysis in patients with pulmonary tuberculosis. Methods Bronchial arterial embolization with PVA grain and silk segment was performed in 42 cases of patients with hemoptysis of secondary pulmonary tuberculosis. Of them, 27 cases were bilateral pulmonary tuberculosis and 15 lateralized. The bloody bronchial arteries were confirmed by bronchial arteriography, and the PVA grains or silk segments were injected slowly into the target vessels until hemorrhage stopped. Results After one time embolization, hemoptysis stopped immediately in 34 cases, 7 cases still had little hemoptysis,and one case of hemorrhage was unable to be controlled. The short-term efficacious rate was 97.6%,and no severe complications occurred. Followed up 6 months to 7 years after treatment,24 cases were clinical cure,7 cases obviously effective,5 cases effective,and 6 cases recurrent.The long-term effective rate is 85.7%. Conclusion Embolization of bronchial artery with PVA grain and silk segment was a safe and effective method for controlling hemoptysis of pulmonary tuberculosis, and its combination with anti-tuberculosis treatment could consolidate the curative effect.
