Application of FMEA model and 6S management method in reducing dispensing errors in PIVAS of children’s hospitals / 中国药房

OBJECTIVE To reduce dispensing errors in pharmacy intravenous admixture service （PIVAS） of children’s hospitals. METHODS The risk of dispensing procedures in our PIVAS was identified by applying failure mode and effect analysis （FMEA） model. Potential failure modes that might lead to dispensing errors in each link were determined， and failure causes were analyzed. The severity， incidence and detection degree of potential failure modes were quantitatively scored， and their risk priority number （RPN） was calculated to screen failure modes that needed to be improved in priority； the corresponding improvement measures were developed by 6S management method from six aspects， namely， finishing （seiri）， rectifying （seiton）， sweeping （seiso）， sanitation （seiketsu）， literacy （shitsuke） and safety. The effect of intervention before and after rectification was evaluated. RESULTS Based on the RPN， 32 potential failure modes were selected， of which a total of 18 critical failure modes that needed to be improved in priority. After implementing corresponding measures according to 6S management method， the RPN of 18 critical failure modes decreased. The total RPN decreased from 497 to 142 with a decrease rate of 71.43%. The error rates of 15 critical failure modes were significantly lower than before implementation （P＜0.05）. CONCLUSIONS Applying FMEA model and 6S management method to the risk control of all aspects of PIVAS workflow can effectively reduce the risk of PIVAS dispensing errors and ensure the safety of children’s intravenous medication.

The “school-enterprise-community” linkage community pharmaceutical care mode based on the “drug enjoying health” mini program began to be applied in July 2022， with 6 185 users， 2 732 recovery records of expired drugs， 941 times of pharmaceutical care， and 3 354 consultation orders. After the intervention， the qualified rate of medication health knowledge mastery， complete compliance rate， and the correct rate of medication behavior in the observation group increased from 33.53% to 76.87%， 20.23% to 46.26%， and 49.71% to 89.80%， respectively； the proportion of the increase after the intervention was higher than that of the control group （P＜0.05）. CONCLUSIONS This mode has effectively improved the quality of community pharmaceutical care， improves the health awareness of community residents in drug use， and promotes the standardization， rationalization and safety of residents’ drug use.

Quality Evaluation of Atractylodis Macrocephalae Rhizoma in Different Production Methods Based on Traditional Traits / 中国实验方剂学杂志

ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Context: Fracture of endodontically treated teeth is a grave sequela that a clinician should seriously ponder. Suitable selection of restorative materials is a requisite for long?term clinical success. Aims: To compare the fracture resistance of endodontically treated teeth restored with three different posts luted using two different cements under all ceramic crowns. Settings and Design: This in vitro study was conducted in the Department of Prosthodontics, Government Dental College, Kottayam, Kerala, India. Methods and Material: Thirty endodontically treated single?rooted mandibular premolars in which post spaces were prepared and divided into three different groups. Group 1 (n = 10): zirconia post group. Group 2 (n = 10): quartz fibre post group. Group 3 (n = 10): glass fibre post group. Each group is sub?divided into two based on the luting system: resin?modified glass ionomer cement (RMGIC) or dual?cure resin cement (DCRC). The fracture resistance testing was performed in a universal testing machine with a crosshead speed of 0.5 mm/min. Statistical Analysis Used: The mean fracture resistance were analysed using independent sample Student t?test and one?way ANOVA. Results: Within the zirconia post group, the mean fracture resistance was higher in DCRC sub?group compared to the RMGIC sub?group and the difference was statistically significant (p = 0.017). The difference in fracture resistance between three different post systems was not found to be statistically significant with respect to both the luting systems. Conclusions: It was observed that when zirconia post is used, the mean fracture resistance was higher in dual?cure resin group compared to the resin?modified GIC group.

Study of Effectiveness of Convalescent Plasma-therapy in Moderate to Severely ill COVID-19 Patients

Background : Convalescent Plasma-therapy, a classic adaptive immunotherapy used in the treatment of SARS, MERS and 2009 H1N1 pandemic with acceptable efficacy and safety in the past. Convalescent Plasma-therapy was taken into consideration in management of COVID-19 disease during the initial days of pandemic but was withdrawn later due to its doubtful beneficial role. This study aims to explore the beneficial role of Convalescent plasma and to determine whether Convalescent Plasma-therapy holds a second chance in treating SARS-CoV-2. Methods : This cross-sectional observational study includes 82 cases of moderate to severely ill COVID-19 patients who received Convalescent Plasma-therapy and 41 controls who didn抰. regular monitoring of Total Leukocyte Count (TLC), PaO2/FiO2 (PaO2 is partial pressure of Oxygen in arterial blood, fractional inspired oxygen (P/F ratio), Neutrophil to Lymphocyte Ratio (N/L ratio) inflammatory markers, respiratory rate, oxygen saturation, ABG and Radiological Imaging was done for comparative analysis.

A modal study of the effect of adjusting density exposure steps on image quality and radiation dose in digital mammography / 中华放射学杂志

Objective:To investigate the effect of adjusting density exposure steps on image quality and radiation dose in digital mammography.Methods:Using the automatic exposure control (AEC) mode of the digital mammography machine, five different gland thicknesses of 4.3, 5.3, 6.3, 7.3, and 8.3 cm were simulated by attaching 0, 1, 2, 3, and 4 PMMA plexiglass plates under the RMI-156 modal body, and the density exposure steps were adjusted to -3, -2, -1, 0, 1, 2, 3, and 4 for each thickness. The target/filter combination, tube voltage, tube current, incident body surface dose (ESD), incident surface air kerma (ESAK), half-value layer (HVL) and the average glandular dose displayed by the device (displayed AGD) were recorded at each step and thickness, and the signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), figure of merit (FOM) and the calculated average glandular dose (calculated AGD) were calculated. Then, the display effects of simulated fibers, simulated calcifications and simulated masses within the modal body were scored subjectively, and the changes in image quality and radiation dose at different steps were analyzed, and the relationships between ESD and ESAK, displayed AGD and calculated AGD, and displayed AGD/ESD and calculated AGD/ESAK were analyzed. A linear fit was used for the steps with SNR, CNR, and FOM, and an exponential function curve fit was used for the steps with mAs, ESAK, and calculated AGD. The differences between ESD and ESAK, displayed AGD and calculated AGD, and displayed AGD/ESD and calculated AGD/ESAK were analyzed by paired-samples t test. Results:The CNR and SNR of mammographic images rose and fell by about 8% with each increase or decrease of one step. The scores of image simulated fibers, simulated calcifications, and simulated masses showed an overall upward trend with increasing steps, but there were still cases where the scores decreased with increasing grades. FOM varied from 97% to 104% at each grade with little variability. ESD, ESAK, displayed AGD, and calculated AGD, which could measure radiation dose, showed an exponential trend of increasing function with increasing steps, with a variation of about 63% to 165%. There were statistically significant differences ( t=-9.61, P=0.001) between ESD (15.14±10.08) and ESAK (16.66±11.07). However, there were no statistically significant differences ( t=1.20, P=0.240) between displayed AGD and calculated AGD, which were 3.66±2.18 and 3.61±1.99, respectively. Conclusions:The adjustment of density exposure steps can make the image quality change linearly and the radiation dose change exponentially with increasing speed, and the mode and magnitude of the adjustment are appropriately stable with high application value.

Objective:To evaluate a wound diagnosis and treatment mode with integrated medical care in the repair of chronic infectious wounds plus bone exposure at lower extremities.Methods:A retrospective analysis was conducted of the 64 patients with chronic infectious wound plus bone exposure at the lower 1/3 of the leg who had been admitted to Department of Orthopedics Trauma and Microsurgery, Zhongnan Hospital of Wuhan University from January 2019 to December 2021. The patients were divided into 2 groups according to the wound diagnosis and treatment mode. In the observation group of 31 patients subjected to the wound diagnosis and treatment mode with integrated medical care led by specialist nurses, there were 24 males and 7 females with an age of (53.6±12.4) years, the wound was located at the tibial side in 15 cases and at the fibular side in 16 cases, the wound areas averaged [28.27 (23.56, 37.70) cm 2], and the time from injury to treatment was (27.3±4.1) d. Evaluation of the patient's condition, wound diagnosis and formulation of treatment protocols were performed jointly by a doctor-nurse team after the patients were admitted, and continuous diagnosis and treatment of the wounds were carried out mainly by specialist nurses during the doctors' follow-up. In the control group of 33 patients subjected to the conventional wound diagnosis and treatment mode led by doctors, there were 25 males and 8 females with an age of (51.3±14.3) years, the wound was located at the tibial side in 17 cases and at the fibular side in 16 cases, the wound areas averaged [27.49 (17.84, 40.45) cm 2], and the time from injury to treatment was (27.6±4.0) d. The 2 groups were compared in the wound healing rate, wound recurrence rate, hospitalization time and patients' satisfaction. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The observation group achieved a significantly higher wound healing rate within 1 month after treatment [83.87% (26/31)] than the control group [60.61% (20/33)], a significantly lower wound recurrence rate within 6 months after treatment [0% (0/31)] than the control group [18.18% (6/33)], significantly shorter hospitalization time [18.0 (15.1, 20.9) d] than the control group [26.8 (18.4, 40.1) d], and significantly higher patients' satisfaction [50 (50, 50) points] than the control group [50 (42, 50) points] (all P<0.05). Conclusion:In the repair of chronic infectious wounds plus bone exposure at lower extremities, the wound diagnosis and treatment mode with integrated medical care led by specialist nurses may result in a higher wound healing rate, a lower wound recurrence rate, a shorter hospital stay and higher patients' satisfaction than the conventional wound diagnosis and treatment mode led by doctors.

Multimodal magnetic resonance imaging of subjective tinnitus related mood disorder / 中华行为医学与脑科学杂志

Subjective tinnitus refers to the subjective sound perception of patients in the absence of an external sound stimulus.Tinnitus patients are often accompanied by emotional disorders, such as depression and anxiety, which seriously affect the quality of life of patients.Therefore, understanding the mechanism underlying the occurrence of tinnitus emotional disorders can help relieve the pain of tinnitus.Tinnitus was considered a simple ear disease in the early stages, but with the progress of neuroimaging technology and the development of animal models, increasing attention has been given to the changes in the neural structure and function of tinnitus patients.As a powerful technique for in vivo investigation of neural activity in the brain, multimodal magnetic resonance has been widely used in the study of subjective tinnitus.By observing the changes of brain structure in subjective tinnitus patients, the neural mechanism of the occurrence and development of tinnitus has been explored.This article reviewed recent multimodal magnetic resonance imaging studies on the neuroimaging mechanisms of tinnitus with mood disorders, compared the differences in neural activity between subjective tinnitus patients and healthy people, and found that the limbic system, default mode network and other neural network abnormalities were closely related to the mood disorders of tinnitus.The application and development of multimodal magnetic resonance techniques in subjective tinnitus were also discussed to elucidate the neural mechanism of subjective tinnitus accompanied by mood disorders with the help of multimodal magnetic resonance techniques.

Changes in functional connectivity in patients with acute mild traumatic brain injury based on a triple-network model: a resting state functional MRI study / 中华行为医学与脑科学杂志

Objective:To investigate the resting state functional connectivity changes of the " triple network model" composed of salient network (SN), executive control network (ECN) and default mode network (DMN) in patients with acute mild traumatic brain injury (mTBI).Methods:From August 2020 to December 2021, forty-five acute mTBI patients (mTBI group) and 40 healthy controls (HC group) with matched sex, age, and education were included.The Montreal cognitive assessment (MoCA) scale was used to evaluate the cognitive status of all subjects.The resting state network (RNS) was established based on independent component analysis (ICA), and the SN, ECN and DMN were extracted, then functional network connectivity (FNC) was analyzed.Subsequently, the correlation between functional connectivity abnormalities and the performance of cognitive impairment was analyzed.SPSS 19.0 was used for statistical analysis and double sample t test was used for comparison between the tow groups. Results:Compared with HC group, mTBI group had enhanced functional connectivity between SN(L-insula) (MNI: x, y, z=-36, 15, 0, t=3.693)and ECN (left superior parietal gyrus, L-SPG) (MNI: x, y, z=-33, -69, 54, t=3.333)(FDR adjust, P<0.05), and decreased functional connectivity between DMN(left superior frontal gyrus, L-SFG) (MNI: x, y, z=-30, 30, 42, t=-4.063)and DMN(L-angular gyrus)(MNI: x, y, z=-21, -66, 33, t=-4.101)(FDR adjust, P<0.05). For FNC analysis, functional network connectivity in SN(IC26)-DMN(IC8) was enhanced in the acute mTBI group and decreased between SN(IC26)-DMN(IC12) and ECN(IC3)-DMN(IC12). The changes of left superior parietal gyrus functional connection were negatively correlated with MoCA score ( r=-0.627, P<0.01), and SN (IC26) -DMN(IC12) connection was positively correlated with MoCA score ( r=0.411, P=0.005). Conclusions:In patients with acute mTBI, the resting functional connectivity changes within and between the networks of the " triple network model" composed of SN, ECN and DMN, and is related to the decline of cognitive function.This will help to better understand the neuropathological mechanism of acute mTBI and post-traumatic cognitive impairment, and may become an effective imaging marker for identifying and predicting cognitive impairment after mTBI.

Application of health failure mode and effect analysis for the airbag pressure management of patients with artificial airways / 中华危重病急救医学

Objective:To analyze the application effect of health failure mode and effect analysis (HFMEA) model in patients with artificial airways in the cardiovascular surgery intensive care unit (CSICU) by establishing a HFMEA project team, and to develop targeted improvement measures and processes.Methods:The patients undergoing cardiovascular surgeries and with established artificial airways in the Shandong Provincial Hospital Affiliated to Shandong First Medical University were recruited from October 2021 to March 2022. The enrolled patients were divided into the conventional management group and the HFMEA model management group according to random number table method. The conventional management group applied the conventional procedures for monitoring the air bag pressure. The HFMEA model management group used the HFMEA model to implement and improve the airbag pressure monitoring process. The efficacy of HFMEA was assessed by comparing the incidence of ventilator-associated pneumonia (VAP), the pass rate of airbag pressure monitoring, the duration of endotracheal intubation and the length of CSICU stay between two groups. The practicability of HFMEA model was evaluated by analyzing the theoretical assessment scores and practical skill scores of nurses and their satisfaction scores with HFMEA.Results:Compared with the conventional management group, the patients in the HFMEA mode management group had a significantly higher rate of passing airbag pressure monitoring [94.99% (2 994/3 152) vs. 69.97% (1 626/2 324), P < 0.01], shorter duration of endotracheal intubation and length of CSICU stay [duration of endotracheal intubation (hours): 6 (7, 12) vs. 6 (8, 13), length of CSICU stay (hours): 40 (45, 65) vs. 41 (46, 85), both P < 0.05], but the incidences of VAP between the two groups were similar. The theoretical assessment scores and practical skill scores of nurses were significantly higher (theoretical assessment score: 44.47±2.72 vs. 37.59±6.56, practical skill score: 44.56±2.66 vs. 40.03±4.32, total score: 89.03±3.07 vs. 77.63±9.56, all P < 0.05) in the HFMEA mode management group. And the satisfaction scores with airbag pressure management were also significantly higher in the HFMEA mode management group (7.72±1.11 vs. 6.44±1.32, P < 0.05). Conclusions:The application of the HFMEA can improve the airbag pressure measures and standardize the monitoring procedures in patients with artificial airways, and reduce the risk of clinical nursing. It is safe and effective for patients with invasive mechanical ventilation in the CSICU.

Practice and exploration of online teaching in clinical medicine education in military teaching hospitals / 中华医学教育探索杂志

With the rapid development of information technology and the change in military education policy in the new era, online teaching has gradually become one of the main approaches to implement the clinical medical education in military teaching hospitals. In this study, the online teaching was performed mainly by pre-recorded teaching, supplemented by online live teaching. Massive open online courses (MOOCs) and the seminar-style teaching were advocated to be used in advanced disciplines. The quality of online teaching was guaranteed through infrastructure provision, teacher arrangement, teaching preparation, teaching interactivity, after-class test, teaching evaluation, supervision, and summary of teaching, which ultimately achieved a good effect. The results of the two-way questionnaires of 26 teachers and 129 students showed that 23.26% (30/129) of students and 65.38% (17/26) of teachers believed that students' learning ability was insufficient. 34.88% (45/129) of students and 23.08% (6/26) of teachers thought that the existing technology could not meet the requirements of online teaching. 55.04% (71/129) of students and 69.23% (18/26) of teachers held the view that the effect of online teaching was inferior to face-to-face teaching. 28.68% (37/129) of students and 57.69% (15/26) of faculty asked for the return of face-to-face education.

Objective:To observe the application effect of mind mapping combined with interactive communication mode in clinical teaching of neurosurgery.Methods:A total of 40 students who practiced in the Department of Neurosurgery in the Affiliated Hospital of Guizhou Medical University from September 2019 to September 2020 were included in the control group, and traditional teaching was adopted; another 40 students who practiced from October 2020 to October 2021 were included in the observation group, and mind mapping combined with interactive communication mode was adopted for teaching. The two groups of students were taught for 2 weeks, and after the teaching, the teaching effect was compared between the two groups. SPSS 25.0 software was used to conduct t-test and Chi-square test. Results:After 2 weeks of teaching, the scores of theoretical knowledge (90.38±4.03) and practical operation skills (93.37±3.48) in the two groups were higher than those before teaching [(85.52±5.26) and (87.25±4.48)], with statistically significant differences ( t=4.63, 6.83, P<0.001). The case analysis score of the two groups was higher than that before teaching, and that of the observation group (86.03±6.07) was higher than that of the control group (79.13±5.57), with statistically significant differences ( t=5.30, P<0.001). The scores of interpersonal communication ability and cooperation ability of the two groups were higher than those before teaching. The scores of interpersonal communication ability (82.53±4.74), cooperation ability (169.73±7.55) of the observation group were higher than those of the control group [(77.93±4.45) and (158.42±8.01)], with statistically significant differences ( t=4.48, 6.49, P<0.001). Conclusion:Mind mapping combined with interactive communication mode can effectively improve the clinical basic knowledge and clinical practice ability of interns in the Department of Neurosurgery, and improve their communication and cooperation ability.
