ABSTRACT

OBJECTIVE To investigate the development of individual therapy of antimicrobial agents in pediatric patients. METHODS A questionnaire survey was conducted to investigate the individual therapy of antimicrobial agents in 30 children’s hospitals and pediatric departments of general hospitals in China. The survey data was analyzed statistically by Microsoft Excel 2007 and SPSS 26.0 software. RESULTS In this survey, 75 questionnaires were collected, and 53 of them were valid with an effective rate of 70.7%. The results showed that 86.7% (26/30) of the hospitals carried out individual therapy of antimicrobial agents in different forms. Clinical needs primarily contributed to the individual therapy in these hospitals, while the insufficient personnel and equipment were the biggest obstacles for individual therapy. The proportions of hospitals, who implemented evidence- based pharmacy, therapeutic drug monitoring (TDM), model-informed precision dosing (MIPD) and antimicrobial-related genetic tests were 70.0%, 80.0%, 30.0% and 33.3%, respectively. Various detection methods of TDM were carried out in various hospitals, and the antimicrobial agents which needed TDM focused on vancomycin and voriconazole. Moreover, nearly half of pharmacists did not know much about MIPD. CONCLUSIONS At present, TDM is the main way to develop individual therapy of antimicrobial agents in various hospitals, but its monitoring coverage and testing standards need to be improved. MIPD and antimicrobial-related gene tests still need to be further promoted in clinical practice.

ABSTRACT

Objective:To investigate the correlation between different degrees of white matter hyperintensities (WMHs) and outcome after intravenous thrombolysis (IVT) in patients with acute ischemic stroke.Methods:Patients with AIS received intravenous thrombolytic therapy with standard dose of alteplase in the First Hospital of Putian City from January 2019 to June 2022 were retrospectively included. The Fazekas scale was used to score the WMHs shown on MRI, and the patients were divided into without or mild WMH group and moderate-to-severe WMH group. The clinical baseline data and the clinical outcome after 3 months of the two groups were compared. The poor outcome was defined as the modified Rankin scale score >2. Multivariate logistic regression analysis was used to determine the influence of the severity of WMHs on the outcome after intravenous thrombolysis. Results:A total of 103 patients with AIS were included. Their age was 64.85±10.89 years old, and 66 (64.1%) were men. There were 60 patients (58.3%) in the without or mild WMH group, and 43 (41.7%) in the moderate-to-severe WMH group. There were significant differences in age, body mass index, systolic blood pressure, baseline National Institutes of Health Stroke Scale (NIHSS) scores, as well as the proportion of patients with hypertension, smoking, hemorrhagic transformation and poor functional outcome at 3 months after onset in different degrees of WMH groups (all P<0.05). There were 73 patients (70.9%) in the good outcome group and 30 (29.1%) in the poor outcome group. There were significant differences in age, body mass index, baseline NIHSS score, WMH score, as well as the proportion of patients with hypertension, large atherosclerotic stroke and symptomatic intracranial hemorrhage between the two groups ( P<0.05). Multivariate logistic regression analysis showed that after adjusting for confounding factors, moderate-to-severe WMHs were the independent risk factors for the poor outcome at 3 months after intravenous thrombolysis (odds ratio 3.810, 95% confidence interval 1.298-1.124; P=0.015). Conclusion:Moderate-to-severe WMHs are associated with the poor outcome in patients with AIS at 3 months after intravenous thrombolysis.

ABSTRACT

Objective:To quantitatively evaluate the retinal ischemia in different retinal regions of diabetic retinopathy (DR) patients in ultra-widefield fluorescein fundus angiography (UWFA) images with ischemic index (ISI), and to explore its correlation with diabetic macular edema (DME).Methods:A cross-sectional study was conducted.Seventy-nine eyes of 79 patients with DR were enrolled in Renmin Hospital of Wuhan University from September 2017 to October 2020, including 44 males (44 eyes) and 35 females (35 eyes) aged 31 to 73 years old, with an average age of (55.95±8.80) years.UWFA and spectral-domain optical coherence tomography (SD-OCT) were performed in all patients.Patients were divided into DME group (37 eyes) and non-DME group (42 eyes) according to the presence or absence of DME in OCT images.The retina in middle phase UWFA images were divided into posterior, middle peripheral and far peripheral regions by ImageJ software, and ISI in each region was calculated.Central macular thickness (CMT) was automatically calculated using the built-in software of the OCT equipment.The correlation between ISI and CMT was analyzed by Spearman rank correlation analysis.This study adhered to the Declaration of Helsinki.The study protocol was approved by the Ethics Committee of Renmin Hospital of Wuhan University (No.WDRY2019-K037). Written informed consent was obtained from each patient prior to any medical examination.Results:The ISI of the total, posterior, middle peripheral and far peripheral retina was 2.460 (0.603, 5.640)%, 2.670 (1.062, 9.574)%, 1.382 (0.245, 4.378)% and 0.000 (0.000, 1.262)%, respectively, with a statistically significant difference among different regions ( χ2=65.307, P<0.001). There were statistically significant differences in ISI between the total and far peripheral, the posterior and middle peripheral, the posterior and far peripheral, the middle and far peripheral (all at P<0.01). ISI of the total, posterior and middle peripheral retina in DME group were significantly higher than those in non-DME group ( U=424.000, P=0.001; U=403.000, P<0.001, U=493.000, P=0.005), but there was no significant difference in the ISI of the far peripheral region between the two groups ( U=609.000, P=0.061). There was no statistically significant correlation between ISI and CMT in the total, posterior, middle peripheral and far peripheral retina in DME group ( rs=-0.134, -0.018, -0.152, -0.163; all at P>0.05). Conclusions:The retinal non-perfusion area in DR eyes is mainly located in the posterior and middle peripheral retina.The ISI of the posterior and middle peripheral retina in DME eyes is significantly higher than that in eyes without DME.ISI of each retinal region may not be related to the severity of DME.

ABSTRACT

Objective:To apply the multi-modal deep learning model to automatically classify the ultra-widefield fluorescein angiography (UWFA) images of diabetic retinopathy (DR).Methods:A retrospective study. From 2015 to 2020, 798 images of 297 DR patients with 399 eyes who were admitted to Eye Center of Renmin Hospital of Wuhan University and were examined by UWFA were used as the training set and test set of the model. Among them, 119, 171, and 109 eyes had no retinopathy, non-proliferative DR (NPDR), and proliferative DR (PDR), respectively. Localization and assessment of fluorescein leakage and non-perfusion regions in early and late orthotopic images of UWFA in DR-affected eyes by jointly optimizing CycleGAN and a convolutional neural network (CNN) classifier, an image-level supervised deep learning model. The abnormal images with lesions were converted into normal images with lesions removed using the improved CycleGAN, and the difference images containing the lesion areas were obtained; the difference images were classified by the CNN classifier to obtain the prediction results. A five-fold cross-test was used to evaluate the classification accuracy of the model. Quantitative analysis of the marker area displayed by the differential images was performed to observe the correlation between the ischemia index and leakage index and the severity of DR.Results:The generated fake normal image basically removed all the lesion areas while retaining the normal vascular structure; the difference images intuitively revealed the distribution of biomarkers; the heat icon showed the leakage area, and the location was basically the same as the lesion area in the original image. The results of the five-fold cross-check showed that the average classification accuracy of the model was 0.983. Further quantitative analysis of the marker area showed that the ischemia index and leakage index were significantly positively correlated with the severity of DR ( β=6.088, 10.850; P<0.001). Conclusion:The constructed multimodal joint optimization model can accurately classify NPDR and PDR and precisely locate potential biomarkers.

ABSTRACT

Objective:To build a small-sample ultra-widefield fundus images (UWFI) multi-disease classification artificial intelligence model, and initially explore the ability of artificial intelligence to classify UWFI multi-disease tasks.Methods:A retrospective study. From 2016 to 2021, 1 608 images from 1 123 patients who attended the Eye Center of the Renmin Hospital of Wuhan University and underwent UWFI examination were used for UWFI multi-disease classification artificial intelligence model construction. Among them, 320, 330, 319, 268, and 371 images were used for diabetic retinopathy (DR), retinal vein occlusion (RVO), pathological myopia (PM), retinal detachment (RD), and normal fundus images, respectively. 135 images from 106 patients at the Tianjin Medical University Eye Hospital were used as the external test set. EfficientNet-B7 was selected as the backbone network for classification analysis of the included UWFI images. The performance of the UWFI multi-task classification model was assessed using the receiver operating characteristic curve, area under the curve (AUC), sensitivity, specificity, and accuracy. All data were expressed using numerical values and 95% confidence intervals ( CI). The datasets were trained on the network models ResNet50 and ResNet101 and tested on an external test set to compare and observe the performance of EfficientNet with the 2 models mentioned above. Results:The overall classification accuracy of the UWFI multi-disease classification artificial intelligence model on the internal and external test sets was 92.57% (95% CI 91.13%-92.92%) and 88.89% (95% CI 88.11%-90.02%), respectively. These were 96.62% and 92.59% for normal fundus, 95.95% and 95.56% for DR, 96.62% and 98.52% for RVO, 98.65% and 97.04% for PM, and 97.30% and 94.07% for RD, respectively. The mean AUC on the internal and external test sets was 0.993 and 0.983, respectively, with 0.994 and 0.939 for normal fundus, 0.999 and 0.995 for DR, 0.985 and 1.000 for RVO, 0.991 and 0.993 for PM and 0.995 and 0.990 for RD, respectively. EfficientNet performed better than the ResNet50 and ResNet101 models on both the internal and external test sets. Conclusion:The preliminary UWFI multi-disease classification artificial intelligence model using small samples constructed in this study is able to achieve a high accuracy rate, and the model may have some value in assisting clinical screening and diagnosis.

ABSTRACT

Objective: To systematically evaluate the impact of acupuncture on exercise-induced fatigue (EIF). Methods: Scopus, Springer Link, Web of Science, PubMed, Cochrane Library, China National Knowledge Infrastructure (CNKI), Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP), and China Biology Medicine Disc (CBM) were systematically searched to identify randomized controlled trials (RCTs) studying acupuncture treatment of EIF from the inception till August 2020. The risk of bias in the included studies was assessed using the Cochrane handbook. RevMan 5.3 was used to conduct statistical analysis on the extracted data. Results: A total of 11 RCTs were included for meta-analysis, involving 531 patients. It was revealed that acupuncture produced more significant effects in alleviating subjective fatigue [standardized mean difference (SMD)=-3.08, 95% confidence interval (CI) (-4.35, -1.81), P<0.001], increasing the hemoglobin content [weighted mean difference (WMD)=3.89, 95%CI (1.37, 6.42), P=0.003], reducing the lactate dehydrogenase content [WMD=-10.63, 95%CI (-17.67, -3.59), P=0.003], reducing the blood lactic acid content [SMD=-2.65, 95%CI (-4.47, -0.83), P=0.004], and down-regulating the levels of serum creatine kinase [SMD=-0.79, 95%CI (-1.10, -0.48), P<0.001] and blood urea nitrogen [WMD=-1.47, 95%CI (-1.84, -1.11), P<0.001] than the control groups. Conclusion: Based on the existing evidence, acupuncture can be recognized as effective in improving EIF and is worthy of promotion in clinical settings.

ABSTRACT

The prevention and treatment of retinopathy of prematurity (ROP) is an important strategic content of blindness prevention and treatment in China. Medical institutions including remote areas have strengthened the awareness of neonatal fundus screening, however, there are problems of vague screening standards, mainly manifested in expanding the scope of screening and even universal screening of newborns. At the same time, all kinds of fundus changes found in the examination cannot be correctly interpreted and handled, which increase the economic and psychological burden of children's families. In addition, with the wide application of intravitreal injection of anti-neovascular endothelial growth factor, problems such as improper grasp of indications and improper treatment of complications have become increasingly prominent. At this stage, it is urgent to strengthen the construction of ROP prevention and control network, which is suitable for China's national conditions, led by the government and coordinated participation of health and medical institutions at all levels.

ABSTRACT

The article reported the clinical, electrophysiological, renal pathology and gene mutation characteristics of a patient with action myoclonus-renal failure syndrome (AMRF). The patient was a young male who developed epilepsy at the age of 16 and gradually developed tremor, ataxia, and myoclonic seizures. Brain magnetic resonance imaging was normal. The electrophysiological manifestations of the nerve were symmetrical multiple sensory and motor nerve conduction velocity deceleration, especially the easily embedded site of the nerve. Renal pathology showed focal segmental glomerulosclerosis. A new complex heterozygous mutation of SCARB2 gene c.534_537delinsCT (chr4:7710074) and c.358G>T (chr4:7710217) was detected in the patient and verified by his family. The 2 heterozygous mutations were respectively from the patient′s parents. AMRF is a rare type of epilepsy in adolescents. The early manifestations were myoclonus or abnormal renal function, with great clinical heterogeneity and easy to be misdiagnosed and missed diagnosis. The final diagnosis depends on genetic testing.

ABSTRACT

Cervical cancer is a common malignant tumor of female reproductive system. The treatment of cervical cancer is based on surgery and radiotherapy (or concurrent chemoradiation). Lower extremity lymphedema (LEL) is a frequent complication after cervical cancer treatment, which significantly affects the quality of life of patients. Both pelvic surgery and radiation for cervical cancer can lead to LEL. The risk factors for LEL are complicated and involving characteristics regarding patient (age, comorbidities, lifestyle, etc.), tumor [International Federation of gynecology and Obstetrics (FIGO) stage, lymph node metastasis, etc.], and treatment (number of resected lymph nodes, removal of circumflex iliac nodes, adjuvant therapy, etc.). Comprehensive measures are proposed to prevent cervical cancer patients from LEL, and further investigations in terms of effectiveness are warranted.

ABSTRACT

The clinical data of a child with ABCB1 rs1045642 T/T genotype and skin photosensitivity induced by Voriconazole were analyzed retrospectively in Beijing Children′s Hospital, Capital Medical University in September 2020.Literature was reviewed to discuss the relationship between ABCB1 genetic polymorphism and Voriconazole pharmacokinetics.The patient was a 6.8-year-old boy, who was diagnosed with primary immunodeficiency disease.Long-term oral Voriconazole was administered for prevention and treatment of fungal infections.Skin photodistributed erythema and pigmentation occurred about 3-4 weeks after treatment.The skin lesions were significantly alleviated about 1 month after the withdrawal of Voriconazole.Gene test showed ABCB1 rs1045642 T/T in the patient.Some studies reported that ABCB1 rs1045642 T/T genotype reduced the clearance rate of Voriconazole.Monitoring such adverse reaction of Voriconazole in clinical practice is important. ABCB1 gene polymorphism is possible to correlate with the pharmacokinetics and adverse reactions of Voriconazole.However, further large-scale clinical studies are warranted to verify it.

ABSTRACT

Objective:To evaluate the clinical efficacy of Wenyang Huoxue Jiedu Decoction combined with trimetazidine tablets in the treatment of patients with acute myocardial infarction (AMI) after interventional therapy.Methods:A total of 90 patients with AMI of syndrome of cold coagulation of heart vein after interventional surgery in the angshan Hongci Hospital , who met the inclusion criteria were enrolled between February 2020 and April 2021, and they were divided into two groups by the random number table method, with 45 in each group. The control group was given conventional western medicine treatments such as anti-coagulation, lipid regulation and oral administration of trimetazidine tablets, while the observation group adopted Wenyang Huoxue Jiedu Decoction on the basis of the control groups. Both groups were treated for 2 weeks. Before and after treatment, TCM symptoms were scored, and serum creatine kinase isoenzyme (CK-MB), cardiac troponin T (cTnT) and myoglobin (MYO) were detected by ELISA. Left ventricular ejection fraction (LVEF), stroke volume (SV) and left ventricular end-systolic diameter (LVESD) were detected by color ultrasonic instrument, and the clinical efficacy was evaluated. Results:The effective rate was 95.6% (43/45) in the observation group and that in the control group was 88.9% (40/45) ( χ2=1.39, P=0.238). The scores of excruciating pain in the chest, wheezing and incapability of supination, chest tightness and shortness of breath and palpitation in the observation group were significantly lower than those in the control group ( t=5.07, 3.43, 4.98, 5.15, P<0.01). After treatment, the levels of CK-MB [(47.62±8.31) U/L vs. (53.49±8.27) U/L, t=3.36], cTnT [(0.48±0.16) μg/L vs. (0.63±0.25) μg/L, t=3.39] and MYO [(125.47±25.63) μg/L vs. (163.28±30.17) μg/L, t=6.41] were significantly lower in the observation group compared to the control group ( P<0.01). The LVESD [(42.15±7.04) mm vs. (46.03±7.26) mm, t=2.57] in the observation group after treatment was significantly lower than that of the control group ( P<0.05), while the LVEF [(56.73±8.34)% vs. (52.49±8.26)%, t=2.42] and SV [(71.58±4.31) ml vs. (65.47±4.23) ml, t=6.79] were significantly higher than those in the control group ( P<0.05 or P<0.01). Conclusion:Wenyang Huoxue Jiedu Decoction combined with trimetazidine tablets can improve the cardiac function, alleviate the myocardial injury, relieve symptoms of patients with AMI of syndrome of cold coagulation of heart vein after interventional surgery.

METHODS Based on the purchase data (Jul. 2016-Jun. 2019)of 18 tertiary children ’s hospitals,the availability of medicines included in the 7th edition of WHO Model List of Essential Medicines for Children (WHO EMLc)and their influential factors were investigated according to standard medicine investigation method recommended by the WHO and Health Action International . RESULTS A totally 189 active ingredients listed in the 7th edition of WHO EMLc were available at 18 tertiary children ’s hospitals in China ,which referred to 229 medicines. The availability of Budesonide inhalation suspension,oral rehydration salt ,Immunoglobulin for injection and Water for injection was 100%. In each quarter from Jul . 2016 to Jun . 2019,the availability of more than half of the medicines exceeded 50%,and the availability of the medicines remained basically stable in each quarter . The overall availability of cardiovascular system medicines and blood system medicines was the highest,while that of antiparasitic medicines and dermatology medicines was lower . There were 28 medicines(12.2%)that were not approved for use in children in China ,the use of which were off -label. The medicines which had been approved for children and which were included in national essential medicine list had a significantly higher availability (P<0.05). CONCLUSIONS The availability of essential medicines for children is generally better at tertiary children ’s hospitals in China . But the use of some essential medicines in children are off -label. In order to ensure the safety and the availability of essential medicines for children ,it is suggested to introduce China ’s essential medicines list for children ,to promote clinical trials in children for commonly used medicines,and to updete the drug manual in time .

ABSTRACT

Objective:To observe and preliminarily discuss the distribution characteristics of the non-perfusion area (NP) of the retina in different stages of diabetic retinopathy (DR) and its changes with the progression of DR.Methods:A retrospective clinical study. From October 2018 to December 2020, 118 cases of 175 eyes of DR patients diagnosed in Eye Center of Renmin Hospital of Wuhan University were included in the study. Among them, there were 64 males with 93 eyes and 54 females with 82 eyes; the average age was 56.61±8.99 years old. There were 95 eyes of non-proliferative DR (NPDR), of which 25, 47, and 23 eyes were mild, moderate, and severe; 80 eyes were proliferative DR (PDR). Ultra-wide-angle fluorescein fundus angiography was performed with the British Optos 200Tx imaging system, and the fundus image was divided into posterior, middle, and distal parts with Image J software, and the ischemic index (ISI) was calculated. The difference of the retina in different DR staging groups and the difference of ISI were compared in the same area. The Kruskal-Wallis test was used to compare the ISI between the different DR staging groups and the Kruskal-Wallis one-way analysis of variance was used for the pairwise comparison between the groups.Results:The ISI of the posterior pole of the eyes in the moderate NPDR group, severe NPDR group, and PDR group were significantly greater than that in the distal periphery, and the difference was statistically significant ( χ 2=6.551, 3.540, 6.614; P=0.000, 0.002, 0.000). In severe NPDR group and PDR group, the ISI of the middle and peripheral parts of the eyes was significantly greater than that of the distal parts, and the difference was statistically significant ( χ 2=3.027, 3.429; P=0.015, 0.004). In the moderate NPDR group, there was no significant difference in ISI between the peripheral and distal parts of the eye ( χ 2=2.597, P=0.057). The ISI of the posterior pole of the eyes in the moderate NPDR group and the PDR group was significantly greater than that in the middle periphery, and the difference was statistically significant ( χ 2=3.955, 3.184; P=0.000, 0.009). In the severe NPDR group, there was no significant difference in ISI between the posterior pole and the middle periphery of the eye ( χ 2=0.514, P=1.000). Compared with the mild NPDR group and the moderate NPDR group, the ISI of the whole retina, posterior pole, middle and distal parts of the PDR group was larger, and the difference was statistically significant ( χ 2=-7.064, -6.349,-6.999, -5.869, -6.695, -6.723, -3.459, -4.098; P=0.000, 0.000, 0.000, 0.000, 0.000, 0.000, 0.003, 0.000). Conclusion:The NP of the eyes with different DR stages is mainly distributed in the posterior pole and the middle periphery. The higher the severity of DR, the greater the NP in the posterior and middle periphery.

METHODS: The relevant guidelines/consensus and systematic review/Meta-analysis literatures at home and abroad were systematically reviewed ,and the re evaluation was carried out from the effectiveness ,safety and economy dimensions to analyze the current situation of clinical use of PPIs in the prevention of drug-induced gastrointestinal injury in adults and children. RESULTS : A total of 14 clinical guidelines/consensus and 10 systematic review/Meta-analysis literatures of PPIs for the prevention of drug-related gastrointestinal injury at home and abroad were sorted out and included. In terms of effectiveness ,PPIs could prevent various drug-related gastric mucosal damage ,gastrointestinal bleeding and other damage to the digestive tract ,but PPIs had not yet obtained the indication for children in China ;PPIs were widely used in the treatment of children ’s digestive tract diseases ,which belonged to off-label medication. In terms of safety ,the common adverse reactions of PPIs included headache ,gastrointestinal symptoms,etc. There may be risks of kidney disease and fracture during long-term application. In terms of economy ,for some patients with digestive tract and cardiovascular disease risk ,the economic benefit of NSAIDs combined with PPIs were higher ; esomeprazole 20 mg and 40 mg daily were equally effective in preventing ulcer recurrence caused by NSAIDs ,but increasing the dose could not improve the preventive effect. CONCLUSIONS :The preventive effect of PPIs on drug-induced gastrointestinal injury is supported by evidence-based evidence. It has good safety in adults and has certain economic benefits ;but it belongs to off-label drug use in children in China ,and the safety and economy still need to refer to the results of adult studies. In the future ,a number of multicenter prospective clinical studies based on Chinese pediatric population are still needed to provide more support for the prevention and treatment of drug-induced gastrointestinal injury by PPIs in children.

ABSTRACT

Objective:To investigate the prognostic value of neuroelectromyography in peripheral facial paralysis and its correlation with House-Brackman classification.Methods:Seventy-eight patients with peripheral facial paralysis who received treatment in Yiwu Central Hospital, China between January 2016 and January 2019 were included in this study. All patients underwent neuroelectromyography. Bilateral nerve conduction velocity, latency, amplitude, and the needle electrode electrogram of orbicularis oris muscles, rbicularis oculi muscles and frontal muscles were analyzed and recorded. After 3 months of treatment, the correlation between prognosis and House-Brackman classification was analyzed.Results:Electromyography examination of 78 patients revealed among 68 patients presenting with prolonged latency, the latency on the affected side was significantly longer than that on the healthy side [(3.78 ± 0.33) ms vs. (2.89 ± 0.35) ms], t = 15.256, P < 0.001]. Among 73 patients presenting with decreased M amplitude, M amplitude on the affected side was significantly lower than that on the healthy side [(0.60 ± 0.27) mV vs. (1.83 ± 0.29) mV, t = 26.522, P < 0.001]. Among 78 patients, normal electromyography findings were observed in 2 patients and abnormal findings in 76 patients, with an abnormal rate of 97.44%. Among 78 patients, 46 patients presented with fibrillation potentials and positive sharp waves in the resting state, 40 patients presented with long duration and multiphase wave percentage of motor unit action potential in mild contraction, and 52 patients presented with abnormal recruitment potential in severe contraction. Three months of follow-up revealed that 23 out of 25 patients with mild peripheral facial paralysis had a complete recovery, with the cure rate of 92.00% (23/25), 28 out of 36 patients with moderate peripheral facial paralysis had a complete recovery, with the cure rate of 77.78% (28/36), 7 out of 10 patients with mild and moderate peripheral facial paralysis had a complete recovery, with the cure rate of 70.00% (7/10), and 3 out of 5 patients with severe peripheral facial paralysis had a complete recovery, with the cure rate of 60.00% (3/5). Conclusion:Neuroelectromyography can improve the accuracy in the identification of injury degree of peripheral facial paralysis and has a strong correlation with House-Brackman classification. Therefore, neuroelectromyography can provide a reference for diagnosis and treatment of peripheral facial paralysis.

ABSTRACT

Objective:To explore the application of web problem-based learning (WPBL) + case-based learning (CBL) combined with clinical pathways in dermatological nursing teaching.Methods:A total of 120 nurses who practiced in the dermatology department of The First Affiliated Hospital of Air Force Medical University from July 2018 to June 2020 were selected as the research objects. According to the nurse practice period, they were divided into a control group and a study group, with 60 people in each group. The control group used traditional teaching, and the study group used WPBL+CBL combined with clinical pathways for teaching. After the teaching, the two groups of practical nurses were assessed for their theoretical and clinical operational abilities, and the comprehensive abilities of the two groups of practical nurses and their satisfaction with teaching were assessed through questionnaire surveys. SPSS 22.0 was used for t test and χ2 test. Results:The theoretical and clinical performance assessment results of the study group were better than those of the control group, and the difference was statistically significant ( P<0.001). The research group was better than the control group in assessment of improving clinical operation ability, independent problem-solving ability, cultivating teamwork ability, improving self-learning ability, improving ability of presenting and analyzing problems, improving comprehensive analysis ability, cultivating clinical thinking ability and comprehensive ability, with statistical significance ( P<0.001). The satisfaction rate of the trainee nurses in the study group was 93.33%, and the satisfaction rate of the trainee nurses in the control group was 31.67%, with statistically significant differences. Conclusion:WPBL+CBL combined with clinical pathways teaching can significantly improve the theoretical and clinical operation ability of dermatology practice nurses, and improve their comprehensive ability and clinical teaching satisfaction rate, which is worthy of application and promotion in clinical nursing teaching.
