Objective To evaluate the value of an optimized three-dimensional inversion-recovery with real reconstruction (3D-real IR) sequence with a longer repetition time (TR, 16 000 ms) based on modulated flip angle technique in refocused imaging with extended echo train (MATRIX) in the endolymphatic hydrops (EH) imaging after intratympanic gadolinium (Gd) administration, and to compare it with a conventional 3D-real IR based on the turbo spin echo (TSE) sequence. Methods From July 2021 to November 2022, twenty-seven patients received both the conventional and optimized 3D-real IR sequences after bilateral intratympanic Gd administration. Images of the two sequences were qualitativly evaluated and compared. Contrast-to-noise ratio (CNR), signal-to-noise ratio (SNR), and area ratio of endolymph against the total lymphatic space from the two sequences were measured and compared. Results 14(25.9%) ears with insufficient contrast for the EH diagnosis on the conventional sequence were clearly displayed on the optimized sequence. Image score, CNR and SNR of the optimized sequence were significantly higher than those of the conventional sequence (P < 0.001). The scanning time of two sequences was similar. The area ratio of endolymph against the total lymphatic space in the cochlear was significantly higher on the conventional 3D-real IR than that on the optimized 3D-real IR (P < 0.001); there was no statistical difference in the vestibule between the two sequences. Conclusions Compared with conventional sequence, optimized 3D-real IR sequence with a longer TR may be better for evaluation of EH after intratympanic Gd administration.

Objective To investigate the value of artificial intelligence-assisted compressed sensing (ACS) technology for intravenous gadolinium contrast-enhanced magnetic resonance imaging of the inner ear using three-dimensional fluid-attenuated inversion recovery (3D-FLAIR) sequence. Methods The patients received gadolinium contrast-enhanced magnetic resonance imaging using ACS and united compressed sensing (uCS) 3D-FLAIR at Zhongshan Hospital, Fudan University from January to November 2024 were prospectively enrolled. The repetition time was 16 000 ms, and acquisition time was 6 min 40 s and 10 min 24 s in ACS 3D-FLAIR and uCS 3D-FLAIR, respectively. The images on the two sequences were evaluated independently by two radiologists. The image quality of the two sequences was subjectively evaluated and compared. The signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were compared between the two sequences. The grading consistencies using two sequences and between the two doctors were analyzed. Results There was no statistically difference in subjective score of image quality between the two sequences. SNR and CNR of the ACS 3D-FLAIR sequence were significantly higher than those of the uCS 3D-FLAIR sequence (P<0.001). The kappa values of grades of cochlear and vestibular endolymphatic hydrops were 0.942 and 0.888 using two sequences (P<0.001). The kappa values of grades of cochlear and vestibular endolymphatic hydrops using the ACS 3D-FLAIR sequence between the two doctors were 0.784 and 0.831, respectively (P<0.001); the kappa values of grades of cochlear and vestibular endolymphatic hydrops using uCS 3D-FLAIR sequence between the two doctors were 0.725 and 0.756, respectively (P<0.001). Conclusions ACS 3D-FLAIR could provide higher SNR and CNR than uCS 3D-FLAIR, and is more suitable for intravenous gadolinium contrast-enhanced magnetic resonance imaging of the inner ear; the endolymphatic hydrops grades using ACS 3D-FLAIR is similar to use uCS 3D-FLAIR.

OBJECTIVE To enhance the training quality of anticoagulation specialty clinical pharmacists, address the resource limitations of a single training base, and promote homogenization of training quality. METHODS A multi-base joint training system for anticoagulation specialty clinical pharmacists in the Beijing area was established. A mixed research method was employed, collecting data through performance comparisons, questionnaires, and qualitative interviews to compare the differences between the joint training model (experimental group, n=16) and traditional teaching model (the control group, n=17). RESULTS The established joint training system encompassed a unified joint training teaching plan, the formation of a joint training teaching team, the establishment of joint theoretical teaching courses, the implementation of joint case discussions and literature presentations, as well as strengthening the assessment throughout the joint training process. Compared to the control group [theoretical assessment of (76.44±3.66) points, case assessment of (84.31±3.27) points], the experimental group students achieved higher scores in theoretical assessment ([ 79.85±4.64) points] and case assessment ([ 88.70±5.51) points] (P<0.05). Through questionnaires and qualitative interviews, the trainees in experimental group were highly satisfied with the joint training model in terms of theoretical learning, communication skills, and teaching interaction. CONCLUSIONS The multi-base collaborative training system for anticoagulation specialty clinical pharmacists can integrate advantageous resources and significantly enhance the training effectiveness of anticoagulation specialty clinical pharmacists, offering value for wider promotion.

ObjectiveTo explore the current situation and influencing factors of humanistic care experience among patients visiting traditional Chinese medicine (TCM) outpatient clinics in China, and to provide a basis for optimizing TCM-characterized services in both TCM and Western medicine hospitals. MethodsA multi-center cross-sectional study was conducted using convenience sampling to select 35 hospitals across 13 provinces in China (including 3 TCM hospitals and 32 TCM outpatient clinics in general hospitals). A total of 3,430 patients were surveyed using the general information questionnaire and the Outpatient Humanistic Care Experience Questionnaire, with data collected via Questionnaire Star. Univariate analysis and multiple linear regression were employed to examine the impacts of patient characteristics, visit characteristics, hospital type (TCM hospital/general hospital), and geographic region (eastern/central/western) on humanistic care experience. ResultsThe total score of humanistic care experience was 194 (188, 233). Univariate analysis showed that gender, educational level, current residence, per capita monthly household income, location attribute of medical institutions, number of previous visits to this hospital, payment method of medical expenses, previous hospitalization history in this hospital, frequency of outpatient visits within the past 12 months, self-rated disease severity, familiarity with the outpatient procedures, implementation of the follow-up service provided by the hospital, satisfaction with follow-up services, the grade of the hospital visited, geographical region of the hospital visited, and the department visited had an impact on the humanistic care experience during outpatient visits (P<0.05). Multivariate analysis demonstrated that educational level (β=0.609, P=0.011), self-rated disease severity (β=-0.646, P=0.047), familiarity with outpatient procedures (β=4.784, P<0.001), satisfaction with follow-up services (β=6.365, P<0.001), and the grade of the hospital visited (β=-5.487, P<0.001) affected the humanistic care experience in outpatient medical treatment, explaining 24.4% of the total variation. ConclusionHumanistic care experience in TCM outpatient clinics is influenced by multiple factors. It is recommended to optimize the medical treatment process, strengthen doctor-patient communication training, and establish a precise follow-up mechanism, with a focus on improving care perceptions among patients with lower education levels and those attending primary-level hospitals, to refine the TCM-characterized service system.

Objective:To evaluate the accuracy and safety profile of a novel cuboid orientation-guided frontal horn ventriculostomy technique in patients with large hemispheric infarction (LHI).Methods:It was conducted a retrospective cohort study of 48 consecutive LHI patients who underwent the innovative ventriculostomy procedure between time period. Primary outcomes included procedural accuracy (success rates, catheter positioning) and safety indicators (complication rates).Results:All the punctured ventricles were small or of normal size. The success rate of puncture was 100%, the success rate of one-time puncture was 87% (42/48), and the average number of puncture was 1.13 times per case. The ratio of well-positioned tube heads was 87.5% (42/48). The actual angle of the inward deviation of the puncture ranged from -2o to 5o, with an average of 0o±0.3o. The depth of puncture was 7.0-8.0 cm ( 7.3±0.3) cm. The incidence of bleeding around the puncture path was 1.3% (2/48 ) and no massive bleeding occurred. At the 6-month follow-up, one case (2.94%) among the 34 survivors had epilepsy.Conclusions:The cuboid orientation-guided frontal horn ventriculostomy technique demonstrates exceptional procedural accuracy and an excellent safety profile in LHI patients, with high first-pass success rates (87.5%) and minimal complications (4.2% minor hemorrhage). These findings support its clinical adoption for this patient population.

Objective To investigate the pollution of antibiotic resistance genes (ARGs) in the Lhasa River and provide a scientific basis for the safety of drinking water for the regional population and the prevention and control of water environment pollution. Methods A total of five water samples were collected in the Lhasa River in July 2022. Using quantitative real-time polymerase chain reaction (qPCR) assay, 19 types of ARGs, including eight “last-resort” ARGs (LARGs) were detected and analyzed. Statistical analysis was conducted using the SPSS 22.0 software, and Student's t-test was used to compare data between two groups. Results All the 19 ARGs were detected with high frequencies, with the aminoglycoside resistance gene aadA having the highest concentration, followed by the sulfonamide resistance gene sul1 and the macrolide resistance gene ermB. Among the eight LARGs, the carbapenem resistance gene blaOXA-48 had the highest concentration. The absolute and relative concentrations of LARGs were lower than those of common ARGs. There was a statistically significant difference in the absolute concentrations between them, but no significant difference was observed in the relative concentrations. Conclusion Both “conventional” ARGs and LAGRs have been detected in the Lhasa River. Although they are at a relatively low level compared to other domestic waters, in view of the serious adverse effects that ARGs, especially LARGs, may cause, the pollution of ARGs in the Lhasa River should be taken seriously.

Objective To compare the effect of three-dimensional visual (3DV) model, three-dimensional printing (3DP) model and computer-aided design (CAD) modified 3DP model in video-assisted thoracoscopic surgery (VATS) sublobular resection. Methods The clinical data of patients who underwent VATS sublobular resection in the Affiliated Hospital of Hebei University from November 2021 to August 2022 were retrospectively analyzed. The patients were divided into 3 groups including a 3DV group, a 3DP group and a CAD-3DP group according to the tools used. The perioperative indexes and subjective evaluation of operators, patients and their families were compared. Results A total of 22 patients were included. There were 5 males and 17 females aged 32-77 (56.95±12.50) years. There were 9 patients in the 3DV group, 6 patients in the 3DP group, and 7 patients in the CAD-3DP group. There was no statistical difference in the operation time, intraoperative blood loss, drainage volume, hospital stay time or postoperative complications among the groups (P>0.05). Based on the subjective evaluations of 4 surgeons, the CAD-3DP group was better than the 3DV group in the preoperative planning efficiency (P=0.025), intuitiveness (P=0.045) and doctor-patient communication difficulty (P=0.034); the CAD-3DP group was also better than the 3DP group in the overall satisfaction (P=0.023), preoperative planning difficulty (P=0.046) and efficiency (P=0.014). Based on the subjective evaluations of patients and their families, the CAD-3DP group was better than the 3DP group in helping understand the vessel around the tumor (P=0.016), surgical procedure (P=0.020), procedure selection (P=0.029), and overall satisfaction (P=0.048); the CAD-3DP group was better than the 3DV group in helping understand the tumor size (P=0.038). Conclusion CAD-modified 3DP model has certain advantages in pre-planning, intraoperative navigation and doctor-patient communication in the VATS sublobectomy.
