Objective:To explore the clinical efficacy of percutaneous balloon compression (PBC) in the treatment of trigeminal neuralgia (TN) based on the double difference (DID) model.Methods:A retrospective case - control study method was adopted to analyze the general data of 130 patients with trigeminal neuralgia (TN) who were treated in the Department of Neurosurgery of Hebei General Hospital from January 2022 to October 2023. Among them, 49 were males and 81 were females. The age was (53.28±11.67) years, ranging from 25 to 80 years old. According to different treatment methods, the patients were divided into an experimental group ( n=63) and a control group ( n=67). Patients in the experimental group were given percutaneous balloon compression (PBC) treatment, while those in the control group were treated with conservative drug therapy. Propensity score matching method was used for 1∶1 matching. After matching, there were 52 cases in each group. The general data of the two groups were compared. The visual analogue scale (VAS), 36-item short form health survey (SF-36) score, Hamilton depression rating scale (HAMD) score, Hamilton anxiety rating scale (HAMA) score, 5-hydroxytryptamine, neuropeptide P, inflammatory factor interleukin-1 (IL-1), tumor necrosis factor-α (TNF-α) before and after treatment, as well as the clinical efficacy of the two groups of patients were comparatively analyzed. Meanwhile, the incidence of postoperative complications in the two groups was compared. The generalized estimating equation (GEE) model was used to analyze the influencing factors of clinical efficacy, and the difference-in-differences (DID) model was used to evaluate the efficacy before and after treatment. Measurement data conforming to the normal distribution were expressed as mean±standard deviation ( ± s), and the t-test was used for comparison between groups; the chi- square test was used for comparison between count data. Results:After treatment, the VAS, SF-36 score, HAMD score, HAMA score, 5-hydroxytryptamine level, neuropeptide P level, IL-1 level, and TNF-α level in the experimental group were (2.98±0.83) points, (75.56±1.18) points, (7.2±0.83) points, (7.15±0.85) points, (76.34±5.47) ng/mL, (50.95±11.01) pg/mL, (29.45±7.08) ng/L, and (21.18±3.55) ng/L respectively. In the control group, there were (3.63±0.95) points, (73.23±1.13) points, (7.98±0.80) points, (8.04±0.84) points, (186.31±11.61) ng/mL, (86.52±13.32) pg/mL, (34.47±6.58) ng/L, and (26.36±5.80) ng/L, respectively. The differences between the two groups were statistically significant ( P<0.05).The cure rate and the total incidence of postoperative complications in the experimental group were 55.77% and 13.46% respectively, while in the control group, they were 40.38% and 30.77% respectively. The differences between the two groups were statistically significant ( P<0.05).The results of the GEE model analysis showed that age, course of disease, VAS, SF-36 score, HAMA score, HAMD score, 5-hydroxytryptamine level, neuropeptide P level, IL-1 level, TNF-α level, treatment method, and the long - diameter ratio of FO significantly affected the clinical efficacy of patients ( P<0.05).The results of the DID model showed that the experimental group was superior to the control group in improving the VAS, SF-36 score, HAMD score, HAMA score, 5-hydroxytryptamine level, neuropeptide P level, IL-1 level, and TNF-α level( P<0.05). Conclusion:PBC can significantly improve the VAS, SF-36 score, HAMD score, HAMA score, 5-hydroxytryptamine, neuropeptide P, IL-1, TNF-α, and incidence of complications in patients with TN. It can also improve the psychological status and quality of life of patients.

Objective To observe the effect of BOC-Phe-Leu-Phe-Leu-Phe(BOC2)on the expression of six types of mitochondrial N-formyl peptides(NFPs)in blood and two formyl peptide receptors(FPRs)in pancreatic tissue of rats with severe acute pancreatitis(SAP),and to explore its mechanism of alleviating inflammatory damage of SAP.Methods Forty male SD rats were randomly divided into four groups:the sham group,the SAP model group,the BOC2 low-dose and the BOC2 high-dose group(0.1 and 0.2 mg/kg),with 10 animals in each group.The SAP model was prepared by retrograde injection of 5%sodium taurocholate(50 mg/kg)into biliary and pancreatic ducts in the last 3 groups.BOC2 was intraperitoneally injected at 0.5 hours after SAP modeling,and samples were taken 4 hours after modeling.HE staining was used to observe pathological changes in pancreas.Western blot assay was used to detect the expression of NFPs in plasma.IHC staining was used to detect the expression of FPRs in pancreatic tissue.ELISA was used to detect interleukin(IL)-1β,IL-6 and tumor necrosis factor(TNF)-α levels in plasma.qPCR was used to detect expression levels of inflammatory factors in local pancreatic tissue.Results Compared with the model group,the BOC2 high-dose group and the BOC2 low-dose group showed improvement in pathological phenomena,such as pancreatic bleeding,acinar cell necrosis,inflammatory cell infiltration and edema.The pancreatic injury score,pancreatic FPRs expression,plasma MT-ND1,MT-ND2,MT-ND3,MT-ND5,MT-ND6 expression,as well as expression levels of three inflammatory factors in plasma and local pancreatic tissue,were significantly reduced(P＜0.05).Conclusion BOC2 can reduce the production of inflammatory factors and alleviate SAP inflammatory damage by antagonizing mitochondrial NFPs/FPRs signaling pathway.

OBJECTIVE To investigate the risk factors for hypokalemia caused by amphotericin B liposome， and to provide reference for clinical use of drugs. METHODS A retrospective analysis was used to collect the information of patients who used amphotericin B liposome during the hospitalization in First Affiliated Hospital of Hainan Medical College from January 2012 to December 2021. The details of use information about amphotericin B liposome and the potassium supplementation were collected. The patients were divided into hypokalemia group and normal group according to the occurrence of hypokalemia. Univariate and multi-variate Logistic regression analyses were used to analyze the risk factors for hypokalemia induced by amphotericin B liposome. RESULTS Of the 121 patients included in this analysis， 60 patients were in hypokalemia group， 61 patients were in normal group. The following parameters of the hypokalemic group were significantly higher or longer than those of the normal group， such as the maintenance dose， cumulative dose and maximum daily dose （in patients with severe hypokalemia） of amphotericin B liposome， treatment days， the maintained days of hypokalemia， daily dose of potassium supplement （in patients with moderate or severe hypokalemia）， the duration of potassium supplement （in patients with moderate hypokalemia）. Results of single factor analysis showed that the cumulative dose of amphotericin B liposome ≥200 mg and the duration of treatment ≥5 days were independent risk factors of hypokalemia caused by this drug （P＜0.05）. Multi-variate analysis results showed that the presence of basic hypokalemia， body weight ＜50 kg， cumulative dose of amphotericin B liposome ≥200 mg and the duration of treatment ≥5 days were the independent risk factors for hypokalemia caused by amphotericin B liposome （P＜0.05）. CONCLUSIONS The incidence of hypokalemia caused by amphotericin B liposome is high， the independent risk factors for hypokalemia include cumulative dose ≥200 mg， treatment days ≥5 days， the presence of basic hypokalemia and body weight ＜ 50 kg. It is suggested that serum potassium should be elevated to normal level before amphotericin B liposome treatment， and the level of serum potassium should be monitored during medication to reduce the occurrence of hypokalemia.

Objective:To investigate the efficacy of percutaneous balloon compression (PBC) in the treatment of trigeminal neuralgia (TN) and the risk factors of postoperative recurrence.Methods:A retrospective case-control study was conducted to collect the clinical data of 200 TN patients admitted to Hebei General Hospital from February 2018 to February 2019. According to different treatment methods, the patients were divided into operation group ( n=150) and conservative group ( n=50). The operation group received PBC treatment, and the conservative group received conservative treatment. The clinical efficacy of the two groups was recorded, including total effective rate, VAS, quality of life score (physical function, health status, social function, mental health). Patients treated with PBC were followed up for 4 years, and were divided into relapse group ( n=23) and non-recurrence group ( n=127) according to postoperative recurrence. The baseline data and laboratory indexes of the two groups were recorded, including fasting blood glucose, procalcitonin, C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-α(TNF-α). Measurement data with normal distribution were expressed as mean±standard deviation ( ± s), and t-test was used for comparison between groups. Chi-square test was used for comparison between count data groups. The factors related to postoperative recurrence of TN patients were first analyzed by univariate analysis, and then by multivariate Logistic regression analysis. A nomogram prediction model was constructed to predict postoperative recurrence, and its prediction efficiency was evaluated. The model was stratified by X-tile software to discuss its clinical application value. Results:The total effective rate, VAS of the operation group were 94.00%, 2.14±0.57, the conservative group were 78.00%, 3.87±1.16, and the difference between the two groups was statistically significant ( P< 0.05). The scores of physical function, health status, social function and mental health of quality of life in the operation group after treatment were 89.75±4.67, 90.36±5.68, 87.68±4.16, 88.79±5.09, the conservative group were 82.54±4.03, 84.67±4.28, 81.45±4.09, 80.69±4.89, and the difference between the two groups was statistically significant ( P< 0.05). Of 150 patients treated with PBC, 23 (15.33%) relapsed. Hypertension( OR=2.537, 95% CI: 1.069-6.019), diabetes( OR=5.179, 95% CI: 1.492-17.970), hyperlipidemia( OR=2.447, 95% CI: 1.227-4.883), CRP≥6.62 mg/L( OR=6.386, 95% CI: 1.738-9.854), IL-6≥19.55 ng/L( OR=8.028, 95% CI: 1.279-12.214), procalcitonin ≥1.13 ng/mL ( OR=7.615, 95% CI: 5.020-14.559), TNF-α≥4.56 ng/L( OR=6.226, 95% CI: 4.950-13.337) were independent risk factors for postoperative recurrence of PBC ( P<0.05). Based on the nomogram constructed by the above 7 risk factors, the decision curve showed that the net benefit rate was greater than 0 when the threshold probability was between 0.01 and 0.91. The X-tile software was used to divide the model into three levels of low (>21.6), medium (13.8-21.6) and high (<13.8) risk according to the Logistic risk score, and the postoperative recurrence probability of PBC was 10.87%, 20.74% and 64.04%, respectively. The recurrence rate of PBC in the high-risk group was significantly higher than that in the medium-risk group and the low-risk group ( χ2=5.136, P=0.015). Conclusions:Percutaneous balloon compression of trigeminal nerve in the treatment of patients with trigeminal neuralgia has the advantages of high total effective rate, fewer postoperative complications, good clinical efficacy, quick effect and so on. The construction of percutaneous balloon compression of trigeminal nerve in patients with trigeminal neuralgia postoperative recurrence risk prediction model to provide reference for clinical improvement of patient rehabilitation.

ObjectiveTo explore the mechanism of Chaihu Guizhitang （CHGZT） in alleviating neuropathic abdominal pain induced by 2，4，6-trinitrobenzene sulfonic acid （TNBS） in rats with chronic pancreatitis （CP）. MethodFifty male SD rats were randomly assigned into five groups： sham operation， CP model， and low-， medium-， and high-dose （4， 8， and 16 g·kg^-1， respectively） CHGZT groups. In the sham operation group， the abdomen was closed after the pancreas was gently stirred. The rat model of CP was established by retrograde injection of 2% TNBS-10% ethanol into the pancreatic duct. The oral administration of CHGZT started 4 weeks after modeling and lasted for 2 weeks. Pain threshold was measured by Von Frey fibers 6 weeks after surgery. Hematoxylin-eosin （HE） staining was employed to reveal the chronic inflammation and fibrosis of the pancreatic tissue. Immunohistochemmistry （IHC） was employed to detect the expression of PGP9.5 （a marker of pancreatic nerves） and reveal the inflammatory changes around the nerves. IHC and immunofluorescence （IF） were used to determine the location of ionized calcium-binding adaptor molecule-1 （Iba-1， microglia marker） and purinergic receptor P2X7 （P2RX7） and the co-expression of P2RX7 and Iba-1 in the thoracic spinal dorsal horn. ResultCompared with the sham operation group， the modeling increased the scores of pancreatic gland atrophy， inflammatory infiltration， and fibrosis （P<0.01）， the abdominal pain response under different force values （P<0.05， P<0.01）， and the score of peripancreatic inflammation. Moreover， the modeling up-regulated the expression of Iba-1 and P2RX7 in the thoracic spinal dorsal horn （P<0.01）. Compared with the model group， the high- and medium-dose CHGZT lowered the scores of pancreatic gland atrophy， inflammatory infiltration， and fibrosis， the abdominal pain response， and the score of peripancreatic inflammation （P<0.05， P<0.01）. The high-， medium-， and low-dose CHGZT all down-regulated the expression of Iba-1 and P2RX7 （P<0.01）. ConclusionCHGZT can significantly relieve abdominal pain in CP rat by suppressing the inflammation around nerves in the pancreas and the P2RX7 activation of microglia in the spinal dorsal horn.

Objective:To explore the value of Caprini risk assessment scale and serum D-dimer in early prediction of postoperative lower extremities deep vein thrombosis (DVT) in patients with gastrointestinal malignant tumor.Methods:A total of 240 patients with gastrointestinal malignant tumors treated in Union Hospital of Tongji Medical College of Huazhong University of Science and Technology from Jan to Oct 2020 were analyzed retrospectively.Results:Caprini score was 4 in 8 cases, 5-7 in 217 cases, and 8 in 15 cases. Sixty-seven patients developed lower extremity DVT after operation. No patients with Caprini score of 4 had DVT, 57 cases (26.3%) with a score of 5-7 had DVT; 10 cases whose score were ≥8 points (66.7%) developed DVT. There was a higher incidence of lower extremity DVT in patients ≥8 points than those of 5-7 points after surgery ( P<0.01). The postoperative Caprini score of the DVT group was higher than that of the non-DVT group (6.37±1.01 vs. 5.80±0.94, t=4.108, P<0.001). D-dimer on the first day after operation in DVT group (4.08±2.27 vs. 2.01±1.04, t=7.715, P<0.001) and the level of serum D-dimer (2.93±1.81 vs. 2.30±1.21, t=2.631, P<0.001) on day 3 was higher than that in the non-DVT group. According to the ROC curve, the best cut-off value for serum D-dimer to predict lower extremity DVT on the first postoperative day was 2.84 mg/L, the sensitivity was 70.1%, the specificity was 87.3%, and the area under the curve (AUC) was 0.815. The best cut-off value of D-dimer for predicting lower limb DVT on day 3 after surgery was 1.67 mg/L, sensitivity was 85.1%, specificity was 34.7%, and AUC was 0.611. Conclusions:Patients with gastrointestinal malignant tumors have a high incidence of postoperative lower extremity DVT. When the serum D-dimer exceeds 2.84 mg/L on the first postoperative day, the likelihood of postoperative lower extremity DVT is higher.

Objective:To investigate the clinicopathological features and prognosis of patients with gastric gastrointestinal stromal tumor (GIST) combined with digestive tract cancer.Methods:The retrospective cohort study was conducted. The clinicopathological data of 1 163 patients with gastric GIST who were admitted to the Union Hospital admitted to Tongji Medical College of Huazhong University of Science and Technology from January 2002 to December 2021 were collected. There were 606 males and 557 females, aged 59(range,20?94)years. Of the 1 163 patients, 129 cases with gastric GIST combined with other digestive tract cancer were divided into the combined group, and 1 034 cases with only gastric GIST were divided into the non-combined group. Observation indicators: (1) clinicopathological features of patients; (2) surgical situations and postoperative complications; (3) follow-up and survival of patients; (4) analysis of prognosis associated affecting factors. Follow-up was conducted using outpatient examination, telephone and online interview to detect survival of patients up to January 2022. The overall survival time was defined as the time from surgery to the last tine of follow-up or the outcome events, such as death of patient, loss of follow-up, etc. Measurement data with normal distribution were represented as Mean± SD, and measure-ment data with skewed distribution were represented as M(range). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Com-parison of ordinal data was conducted using the non-parameter Mann-Whitney U test. Kaplan-Meier method was used to draw survival curves and calculate survival rates, and Log-Rank test was used to conduct survival analysis. The COX proportional hazard model was used for univariate and multivariate analyses. Results:(1) Clinicopathological features of patients. Of the 129 patients in the combined group, there were 81 cases combined with gastric cancer, 39 cases combined with esophageal cancer, 8 cases combined with colon cancer and 1 case combined with rectal cancer. Gender (male, female), cases with age ≤60 years or>60 years, cases without or with clinical symp-toms before surgery, cases with tumor diameter of gastric GIST as<2 cm, 2?5 cm, 5?10 cm,>10 cm, cases with mitotic index as <5/50× high power field, 5?10/50× high power field, >10/50× high power field, cases with cell proliferation index of Ki-67 as ≤5% or >5%, cases classified as extremely low risk, low risk, medium risk and high risk of the modified national institutes of health (NIH) risk classification, cases with or without tumor necrosis of the gastric GIST, cases without or with adjuvant imatinib therapy, cases with the expression of DOG-1 detected by immunohistochemical staining as positive or negative, cases with the expression of CD34 as positive or negative were 92, 37, 30, 99, 9, 120, 114, 10, 3, 2, 126, 1, 2, 122, 2, 112, 8, 5, 4, 129, 0, 121, 8, 118, 3, 117, 12 in the combined group, versus 514, 520, 585, 449, 194, 840, 383, 360,201, 90, 799, 155, 80, 851, 143, 337, 308, 192, 197, 960, 74, 769, 265, 850, 80, 990, 44 in the non-combined group, showing significant differences in the above indicators between the two groups ( χ2=21.46, 51.11, 11.06, Z=?10.27, ?5.34, χ2=15.94, Z=?10.61, χ2=9.86, 24.10, 5.52, 6.37, P<0.05). Of the 1 163 patients, there were 12 cases of the combined group suspected diagnosed as gastric GIST before surgery and 1 case of the combined group dia-gnosed as gastric GIST by gastroscopy and pathological examination before surgery. The rest of 1 150 patients were diagnosed as gastric GIST by intraoperative exploration or postoperative pathological examination. (2) Surgical situations and postoperative complications. Of the 129 patients in the combined group, 72 cases underwent open surgery and 57 cases underwent laparoscopic or thoracoscopic surgery including 3 cases converted to open surgery. Of the 1 034 patients in the non-combined group,207 cases underwent endoscopic surgery, 371 cases underwent open surgery, and 456 cases underwent laparoscopic or thoracoscopic surgery including 8 cases converted to open surgery. Incidence of postoperative complications was 10.078%(13/129) in the combined group, versus 2.321%(24/1 034) in the non-combined group, showing a significant difference between the two groups ( χ2=22.40, P<0.05). (3) Follow-up and survival of patients. Of the 1 163 patients, 1 046 cases were followed up for 44(range, 1?220)months, with the postoperative 5-year overall survival rate as 87.2%. The postoperative 5-year overall survival rate was 51.2% in the combined group, versus 91.4% in the non-combined group, showing a significant difference between the two groups ( χ2=169.07, P<0.05). (4) Analysis of prognosis associated affecting factors. Results of univariate analysis showed that gender, age, tumor diameter of gastric GIST as 2?5 cm, 5?10 cm and >10 cm, combined with other digestive tract cancer, mitotic index as >10/50× high power field and tumor necrosis of the gastric GIST were related factors affecting the postoperative 5-year overall survival rate of patients with gastric GIST ( hazard ratio=2.16, 2.27, 0.46, 0.57, 1.75, 7.58, 2.70, 1.80, 95% confidence intervals as 1.52?3.07, 1.60?3.22, 0.29?0.71, 0.34?0.94, 1.11?2.77, 5.29?10.85, 1.67?4.38, 1.08?2.98, P<0.05). Results of multivariate analysis showed that gender, age, tumor diameter of gastric GIST, combined with other digestive tract cancer and mitotic index were independent factors affecting the post-operative 5-year overall survival rate of patients with gastric GIST ( hazard ratio=1.91, 1.82, 2.10, 7.11, 2.75, 95% confidence intervals as 1.33?2.75, 1.27?2.62, 1.14?3.87, 4.58?11.04, 1.50?5.03, P<0.05). Conclusions:The tumor diameter of gastric GIST is short in patients combined with other digestive tract cancer, and the risk grade of modified NIH risk classification is lower. Gender, age, tumor diameter of gastric GIST, combined with other digestive tract cancer and mitotic index are independent factors affecting the postoperative 5-year overall survival rate of patients with gastric GIST.

Objective:To evaluate the clinical outcomes of additional surgery after non-curative endoscopic submucosal dissection (ESD) for early gastric cancer.Methods:Sixty-nine patients with early gastric cancer who underwent ESD and were diagnosed as having non-curative resection by postoperative pathology at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology from January 2014 to December 2020 were included in the retrospective observation. Patients were divided into the additional surgery group ( n=12) and the follow-up group ( n=57). The differences in clinical and pathological data of the two groups, the surgical outcomes of the additional surgery group, three-year recurrence-free survival and tumor-specific survival of the two groups, and the independent risk factors affecting three-year recurrence-free survival in the follow-up group were analyzed. Results:Compared with the follow-up group, the rates of submucosal infiltration [66.7% (8/12) VS 21.1% (12/57), χ 2=7.927, P=0.005], vascular invasion [33.3% (4/12) VS 1.8% (1/57), P=0.003] and nerve invasion [16.7% (2/12) VS 0.0% (0/57), P=0.028] in the additional surgery group were significantly higher. In the additional surgery group, the interval between the additional surgery and ESD was 18.5 d (7-55 d), the surgical time was 286.4±85.9 min, and the number of dissected lymph nodes was 25.6±7.4. Four patients (33.3%) had residual tumor. Postoperative complications occurred in 4 patients (33.3%) (all were discharged after conservative treatment), and there was no perioperative death. One patient developed liver metastases 17 months after the surgery, and died 22 months after surgery due to liver metastases. One patient died 22 months after surgery due to non-tumor causes. The three-year recurrence-free survival and three-year tumor-specific survival in additional surgery group were 91.7% (11/12) and 91.7% (11/12), respectively, and those in the follow-up group were 87.7% (50/57) and 100.0% (57/57), respectively. Multivariate Cox regression analysis showed that tumor size ≥2 cm was an independent risk factor for three-year recurrence-free survival in the follow-up group ( P=0.037, HR=15.595, 95% CI: 1.181-205.952). Conclusion:Additional surgery and close follow-up are safe and feasible therapeutic strategies for early gastric cancer patients who underwent non-curative ESD. Clinicians should make reasonable choice based on the pathological results, patients' physical condition and surgery intention. But for patients with primary tumor size ≥2 cm, additional surgery is recommended.

Objective:To investigate the effect of transcranial direct current stimulation (tDCS) on the behavior and the mismatch negativity (MMN) component of the auditory evoked potential of autistic children.Methods:Thirty-four autistic children were randomly divided into an anode stimulation group ( n=19) and a pseudo-stimulation group ( n=16). Both groups were given one hour of routine rehabilitation five times a week for 4 weeks, while the anode stimulation group was additionally provided with 20 minutes of tDCS 3 times a week. Before and after the treatment, both groups′ behavior was evaluated by using autism behavior checklist (ABC) as well as any changes in MMN of the auditory evoked EEG signals. Results:There were no significant differences between the two groups in any of the measurements before the treatment. Afterwards behavior had improved significantly in both groups, with significantly greater improvement in the stimulated group. In the stimulated group the average MMN amplitude had increased significantly and the average latency had decreased significantly. However, no such significant changes were observed in the pseudo-stimulation group. There was a significant linear correlation between the changes in the incubation period of MMN components and the improvements in ABC, vestibular functioning, tactile defense and proprioception.Conclusion:Anodal tDCS combined with conventional rehabilitation therapy can effectively increase the MMN amplitude and shorten the latency in autistic children, improving their brain function.

Objective:To explore the teaching effect of magnetic on-demand teaching mode in nursing interns of neurology department.Methods:Forty-two nursing students who practiced in Neurology Department of Haikou People's Hospital from July 2019 to December 2019 were selected as the control group, and 44 nursing students who practiced from January 2020 to June 2020 were selected as the study group. The traditional teaching mode was adopted in the control group, while the magnetic on-demand teaching mode was adopted in the study group. The scores of theory and skill examination after teaching, nurses' core competence (evaluated by nurse core competence scale) before and after teaching, active learning rate and incidence of nursing errors during teaching and satisfaction with teaching were compared between the two groups. SPSS 25.0 was used for t test and chi-square test. Results:After teaching, the scores of theory and skills in the study group were significantly higher than those in the control group ( P<0.05). After teaching, the scores of core competence of nurses in the two groups were higher than before, and the scores of core competence of nurses in the study group were higher ( P<0.05). During the teaching period, the active learning rate of the study group was higher than that of the control group ( P<0.05), and the incidence rate of nursing errors was lower than that of the control group ( P<0.05). The satisfaction of all kinds of teaching in the study group was higher than that in the control group, with statistically significant differences. Conclusion:In the clinical teaching of nursing interns in neurology department, the magnetic on-demand teaching mode can significantly enhance the mastery of nursing theory and skills, improve the core competence of nurses, improve the active learning rate and teaching satisfaction, and reduce the occurrence of nursing errors.
