ABSTRACT
Objective To compare the image quality of carotid contrast-enhanced magnetic resonance angiography(ceMRA)under different flow rates using high relaxation rate contrast agent named Gadobutrol,and to find the best flow rate for carotid ceMRA.Methods Total of 117 patients,who were scheduled to perform carotid ceMRA examination using Gadobutrol with a dosage of 0.1 mL/kg body weight on a 1.5T MR platform,were enrolled in the study.They were divided into four groups according to four kinds of flow rates,which were 1.0 mL/s(n=29),1.5 mL/s(n=30),2.0 mL/s(n=30)and 3.0 mL/s(n=28).The signal-to-noise ratio(SNR)of bilateral carotid initiation and bilateral carotid bifurcation were calculated.The SNR of carotid initiation or carotid bifurca-tion between different flow rates were compared.And the scores of image quality among different flow rates were also compared.Results For bilateral carotid bifurcations and carotid initiations,the SNR under 1.5 mL/s were highest,which were significantly higher than those under 1.0 mL/s,while there were no significant differences between each two other flow rates.For the bilateral carotid bifurca-tions,the SNR under 1.0 mL/s were lower than those under other flow rates,and were significantly lower than those under 1.5 mL/s and 3.0 mL/s.The score of the image quality at 1.0 mL/s was significantly lower than that under other flow rates.The score of the image quality at 1.5 mL/s was the highest,but no significant difference was found compared to that at 2.0 mL/s or 3.0 mL/s.Conclusion The rate of 1.5 mL/s is recommended as the best flow rate for carotid ceMRA with Gadobutrol based on 1.5T MR.
ABSTRACT
BACKGROUND:Some studies have shown that the hounsfield units(HU)value based on lumbar CT can be used to screen osteoporosis.At present,the number of patients with pulmonary infection has increased;the number of patients with pulmonary infection and type 2 diabetes is also increasing,which increases the utilization rate of chest CT. OBJECTIVE:To investigate the role of lumbar 1 vertebral body HU value based on chest CT in the screening of type 2 diabetes mellitus osteoporosis. METHODS:The clinical data of 244 patients with type 2 diabetes mellitus treated in the First Affiliated Hospital of Chengdu Medical College from June 2020 to June 2022 were analyzed retrospectively.The bone mineral density was obtained by dual-energy X-ray absorptiometry.According to WHO's diagnostic criteria for osteoporosis,the subjects were divided into the non-osteoporosis group(n=120)and the osteoporosis group(n=124).The general condition,T value and HU value of lumbar 1 vertebra in chest CT were compared,and the relationship between the HU value and T value of each position was analyzed and the accuracy of type 2 diabetes mellitus osteoporosis was evaluated. RESULTS AND CONCLUSION:(1)There was no significant difference in sex,age,body mass index,glycosylated hemoglobin,mean blood glucose,calcium(Ca),phosphorus(P),time of type 2 diabetes mellitus,history of hypertension and history of hyperlipidemia between the two groups(P>0.05).(2)The HU value was positively correlated with the lowest T value of the hip(r=0.619,P<0.01);the HU value was positively correlated with the hip T value(r=0.584,P<0.01),and the HU value was positively correlated with the femoral neck T value(r=0.641,P<0.01).When the HU value was 98,the prediction of type 2 diabetes mellitus osteoporosis had good accuracy,and the sensitivity was 70.8%.(3)It is concluded that the HU value of the lumbar 1 vertebra based on chest CT examination is of good value for osteoporosis screening in patients with type 2 diabetes mellitus,and may be an opportunistic and cost-free supplementary screening method for type 2 diabetes mellitus osteoporosis.
ABSTRACT
BACKGROUND:Sema3A is a power secretory osteoprotective factor.However,studies about Sema3A-modified dental pulp stem cells(Sema3A-DPSCs)are rare. OBJECTIVE:To explore the osteogenic differentiation ability of Sema3A-DPSCs and their regulatory effect on the osteogenic differentiation of the pre-osteoblast cell line MC3T3-E1. METHODS:First,Sema3A-DPSCs were constructed using a lentivirus infection system carrying the Sema3A gene.Control lentivirus-treated DPSCs(Vector-DPSCs)were used as controls.Sema3A-DPSCs or Vector-DPSCs were co-cultured with proosteoblast line MC3T3-E1 at the ratio of 1∶1 and 1∶3 for 24 hours.Finally,the Sema3A-DPSCs,Vector-DPSCs and their co-cultured cells with MC3T3-E1 were cultured for osteogenic induction and differentiation.Osteogenic gene expression was detected by alkaline phosphatase staining,alizarin red staining and real-time quantitative RT-PCR to evaluate osteogenic differentiation ability. RESULTS AND CONCLUSION:(1)Sema3A mRNA and protein expression levels in Sema3A-DPSCs were significantly up-regulated.The level of secreted Sema3A in cell supernatant was up-regulated.(2)Compared with the Vector-DPSCs,mRNA expressions of osteogenic genes alkaline phosphatase,Runt-related transcription factor 2,osteocalcin and Sp7 transcription factors in Sema3A-DPSCs were up-regulated;the activity of alkaline phosphatase was enhanced,and the formation of mineralized nodules increased.(3)There were no obvious differences in proliferation between Sema3A-DPSCs and Vector-DPSCs.(4)Compared with MC3T3-E1/Vector-DPSCs co-culture system,the expression of MC3T3-E1 osteogenic genes was up-regulated,and the total alkaline phosphatase activity was enhanced and more mineralized nodules were formed in the MC3T3-E1/Sema3A-DPSCs co-culture system.(5)The results suggest that overexpression of Sema3A can enhance the osteogenic differentiation of DPSCs.Overexpression of Sema3A in DPSCs can promote osteogenic differentiation of MC3T3-E1 in the DPSCs/MC3T3-E1 co-culture system.
ABSTRACT
BACKGROUND:There are few studies on the effect of degeneration of paraspinal muscle on osteoporotic vertebral compression refractures treated by percutaneous vertebroplasty in postmenopausal women.This paper intends to reveal the relationship between them. OBJECTIVE:To investigate the relationship between degeneration of paraspinal muscle and osteoporotic vertebral compression refractures in postmenopausal women treated by percutaneous vertebroplasty. METHODS:The medical records of 81 postmenopausal female patients who were admitted to the First Affiliated Hospital of Guangzhou University of Chinese Medicine from May 2018 to March 2021 for osteoporotic vertebral compression fracture and received percutaneous vertebroplasty were retrospectively analyzed.The patients were divided into an osteoporotic vertebral compression refracture group(n=39)and a control group(n=42)according to whether they had osteoporotic vertebral compression refracture after percutaneous vertebroplasty.General data,vertebral bone mineral density,paravertebral cross-sectional area and mean CT value(Hu)of the two groups were analyzed. RESULTS AND CONCLUSION:(1)Univariate analysis showed that there was no significant difference in age and mean CT value of psoas major between the two groups(P>0.05).The body mass index,vertebral bone mineral density,paravertebral cross-sectional area and the mean CT value of the posterior vertebral muscle group in the control group were significantly higher than those in the osteoporotic vertebral compression refracture group(P<0.05).(2)Multivariate logistic regression analysis showed that low vertebral bone mineral density(OR=0.004,95%CI:0.000-0.555,P<0.05)and low mean CT value of posterior vertebral muscle group(OR=0.940,95%CI:0.894-0.988,P<0.05)were independent risk factors for postmenopausal osteoporotic vertebral compression refracture.(3)It is indicated that degeneration of paraspinal muscle will increase the risk of osteoporotic vertebral compression refractures in patients treated by percutaneous vertebroplasty,especially in postmenopausal women with a low mean CT value of low posterior vertebral muscle group.
ABSTRACT
BACKGROUND:The reciprocal force generated by the molar distalization with clear aligners can lead to anchorage loss.The effect of arch shapes and missing second premolars on anchorage has not been reported. OBJECTIVE:To analyze the effect of arch shapes and missing second premolars on anchorage during molar distalization with clear aligners using the finite element method. METHODS:Cone-beam CT data from an adult male were acquired from the database to establish the maxilla-upper dentition-periodontium-rectangular attachment-clear aligner model.The distal movement amount designed on the bilateral second molars was set to 0.25 mm.First,there were two groups in the study:second premolar bilateral presence and absence groups.Then,four subgroups in each group were created:tapered arch,ovoid arch,square Class Ⅱ Division 1 arch,and Class Ⅱ Division 2 arch groups.The Ansys software was used to calculate the displacement of the anchorage tooth and the stress of the periodontal ligament. RESULTS AND CONCLUSION:Mesial tipping and extrusion of first molars and premolars,labial inclination and intrusion of anterior teeth occurred during the upper second molar distalization with clear aligners.When the bilateral second premolars were missing,the mesial displacement of first molars increased significantly while that of first premolars and anterior teeth decreased in all groups.The square Class Ⅱ Division 1 arch group showed the least anterior labial inclination,while the tapered arch group showed the most.There was no significant difference between the ovoid arch group and the tapered arch group.Moreover,the magnitude of tipping in the square Class Ⅱ Division 2 arch group was slightly higher than that in the Class Ⅱ Division 1 arch group.The stress of the periodontal ligament of the anchorage teeth was concentrated on the cervical and apical regions of the teeth.And the lowest stress level was detected in the square arch group.Compared with the other groups,the stress on the labial cervical area of the periodontal ligaments was also significantly relieved in the square arch group.To conclude,the square arch is more favorable in terms of anterior anchorage control and periodontal ligament stress distribution.Anterior labial inclination efficiency can be increased in cases of Class Ⅱ Division 2 by designing the anterior labial inclination in conjunction with molar distalization.If the second premolar is missing during molar distalization,it is not conducive to opening up the space in the area of the missing tooth.
ABSTRACT
BACKGROUND:The thin alveolar bone in the lower anterior region increases the risk of labial bone resorption when intruding the teeth with clear aligners.The effect of sagittal overcorrection design on the labiolingual control of mandibular anterior teeth intrusion has not been fully investigated. OBJECTIVE:To explore the effect of overcorrection on the changes in the displacement and stress of the mandibular anterior teeth,especially the cervical and apical regions. METHODS:Through a male volunteer cone-beam CT data,the three-dimensional reconstruction of the mandible and teeth was conducted in the MIMICS and GEOMAGIC software.Moreover,the models of periodontal ligaments,attachments,and appliances were created in the SOLIDWORKS software.First,the study was divided into canine intrusion group and incisor intrusion group.Then,the overcorrection(0°,1°,2°)was designed on the bilateral mandibular central and lateral incisors.A total of six models were established.The models were assembled and imported into the ANSYS software to analyze and calculate the displacement and stress level. RESULTS AND CONCLUSION:(1)In the canine intrusion group,canines intruded and tipped lingually while incisors extruded and tipped lingually.In the incisor intrusion group,canines extruded and tipped lingually while incisors intruded and tipped lingually.(2)Without overcorrection,the incisors necks moved lingually while apexes moved labially.With overcorrection,the incisors tended to be upright,followed by labial tilt.The least cervical and apical displacements were detected under 1° overcorrection.(3)With overcorrection,the incisal cervical stress concentration area shifted from labial to lingual in the canine intrusion group,whereas the stress concentration area shifted from lingual to labial in the incisor intrusion group.(4)The incisors tended to tilt lingually when intruding the mandibular anterior teeth with clear aligners.The sagittal overcorrection design was conductive to maintain the stable position of incisors.However,the amount of overcorrection should be moderate.Excessive overcorrection might increase the labial inclination tendencies of incisors.
ABSTRACT

ABSTRACT
Tracheostomy is a very common airway procedure in the treatment of critically ill neurological patients. At present, the traditional tracheal cannula fixation belt is easy to be contaminated, difficult to disinfect, and needs to be replaced regularly. It is prone to infection, skin injury, unplanned extubation and other adverse events, which cannot meet the clinical treatment effect and patient safety management. In order to overcome the above problems, the medical staff of the neurology intensive care unit of Henan Provincial People's Hospital designed a new type of tracheal cannula fixation belt to increase patient comfort and reduce complications, and obtained a National Utility Model Patent of China (ZL 2022 2 0855188.8). The main structure of the device includes a following shaped bending plate, a fastening belt, a locking pin, and a distance adjustment hole. The left and right sides of the shaped bending plate are equipped with fastening belts with breathable and anti-wear pads. The inner side of the left fastening belt is equipped with two sets of locking pins, and the outer surface of the right fastening belt and breathable and anti-wear pad is equipped with multiple sets of distance adjustment holes. Additionally, the back of the shaped bending plate is equipped with breathable buffer pads. The fastening belt can drive the following bending plate to stick tightly to the patient's neck. The operator installs the locking pin card into the distance adjustment hole according to the "one back" principle, and the fastening belts on both sides fix the device with the cooperation of the locking pin, greatly reducing the probability of excessive displacement of the tracheal tube during use, effectively improving the fixation effect of the device, strengthening the adaptability of the device to different personnel, and thus enhancing the practicality of the device. The new type of tracheal cannula fixation band is convenient, safe and efficient, which can increase patient comfort, reduce complications. It has certain clinical value and is suitable for clinical promotion.

For the purpose of real-time portable microalgae detection, a real-time microalgae detection system of low detection requirement and fast detection speed is needed. MethodsThis study has developed a microalgae detection system based on deep learning. A microscopy imaging device based on bright field was constructed. With imaged captured from the device, a neural network based on YOLOv3 was trained and deployed on microcomputer, thus realizing real-time portable microalgae detection. This study has also improved the feature extraction network by introducing cross-region residual connection and attention mechanism and replacing optimizer with Adam optimizer using multistage and multimethod strategy. ResultsWith cross-region residual connection, the mAP value reached 0.92. Compared with manual result, the detection error was 2.47%. ConclusionThe system could achieve real-time portable microalgae detection and provide relatively accurate detection result, so it can be applied to periodic test in microalgae farming.
ABSTRACT
@#Objective To analyze the clinical characteristics of stiff left atrial syndrome (SLAS) after Mei mini maze procedure for atrial fibrillation (AF), and to explore its risk factors and treatments. Methods We retrospectively analyzed the clinical data of the patients who underwent Mei mini maze procedure in Xinhua Hospital between 2010 and 2020. According to whether SLAS occurred in the early postoperative period, patients were divided into a SLAS group and a non-SLAS group. The basic data, perioperative echocardiogram and laboratory test indexes of the two groups were compared. Results A total of 1 056 patients were collected. There were 672 (63.6%) males with an average age of 63.6±9.3 years, including 489 patients with persistent AF and 567 patients with paroxysmal AF. Fourteen (14/1 056, 1.3%) patients developed SLAS, with an average occurrence time of 2.1±1.1 days after the surgery. The average follow-up time of the whole group was 21.4±7.8 months. Two patients in the SLAS group developed SLAS again after discharge, and the occurrence time was 3 weeks and 4 weeks after the operation, respectively; while no SLAS occurred after discharge in the non-SLAS group. Diabetes and small preoperative left atrial diameter were risk factors for SLAS after surgery. Patients with SLAS had a good prognosis after adequate diuretic therapy. Conclusion The incidence of SLAS after Mei mini maze procedure for AF is low, and it mostly occurs in the early postoperative period. After adequate diuretic treatment, the prognosis is good.
ABSTRACT
Objective@#: Blood-blister aneurysms (BBAs) of the internal carotid artery (ICA) are challenging lesions with high morbidity and mortality rates. Although research on BBAs is well documented in different populations, the study of BBAs in the Tibetan population is extremely rare. This study aimed to evaluate the characteristics of BBAs and analyze the treatment modalities and long-term outcomes in the Tibetan population in comparison with the Han population. @*Methods@#: The characteristics of patients with BBAs of the ICA from January 2009 to January 2021 at our institution were reviewed. The features of aneurysms, treatment modalities, complications, and follow-up outcomes were retrospectively analyzed. @*Results@#: A total of 130 patients (41 Tibetan and 89 Han patients) with BBAs of the ICA who underwent treatment were enrolled. Compared with the Han group, the Tibetan group significantly demonstrated a high ratio of BBAs among ICAs (8.6%, 41/477 vs. 1.6%, 89/5563; p<0.05), a high ratio of vasospasm (34.1%, 14/41 vs. 6.7%, 6/89; p=0.001), a high risk of ischemic events (43.9%, 18/41 vs. 22.5%, 20/89; p<0.05), and a low ratio of good outcomes (modified Rankin scale, 0–2) at the 1-year follow-up (51.2%, 21/41 vs. 74.2%, 66/89; p<0.05). The multivariate regression model showed that ischemic events significantly contributed to the prediction of outcomes at 1 year. Further analysis revealed that microsurgery and vasospasm were associated with ischemic events. @*Conclusion@#: In comparison with Han patients, the Tibetan population had a high ratio of BBA occurrence, a high incidence of ischemic events, and a high ratio of poor outcomes. The endovascular approach showed more benefits in BBA patients.
ABSTRACT
Objective@#Anxious depression is a prevalent characteristic observed in Asian psychiatric patients diagnosed with major depressive disorder (MDD). This study aims to investigate the prevalence and clinical presentation of anxious depression in Taiwanese individuals diagnosed with MDD. @*Methods@#We recruited psychiatric outpatients aged over 18 who had been diagnosed with MDD through clinical interviews. This recruitment took place at five hospitals located in northern Taiwan. We gathered baseline clinical and demographic information from the participants. Anxious depression was identified using a threshold of an anxiety/somatization factor score ≥7 on the 21-item Hamilton Rating Scale for Depression (HAM-D). @*Results@#In our study of 399 patients (84.21% female), 64.16% met the criteria for anxious depression. They tended to be older, married, less educated, with more children, and an older age of onset. Anxious depression patients had higher HAM-D and Clinical Global Impression–Severity scale score, more panic disorder (without agoraphobia), and exhibited symptoms like agitation, irritability, concentration difficulties, psychological and somatic anxiety, somatic complaints, hypochondriasis, weight loss, and increased insight. Surprisingly, their suicide rates did not significantly differ from non-anxious depression patients. This highlights the importance of recognizing and addressing these unique characteristics. @*Conclusion@#Our study findings unveiled that the prevalence of anxious depression among Taiwanese outpatients diagnosed with MDD was lower compared to inpatients but substantially higher than the reported rates in European countries and the United States. Furthermore, patients with anxious depression exhibited a greater occurrence of somatic symptoms.
ABSTRACT
BACKGROUND@#Insufficient angiogenesis and the lack of skin appendages are critical challenges in cutaneous wound healing. Stem cell-fabricated cell sheets have become a promising strategy, but cell sheets constructed by a single cell type are inadequate to provide a comprehensive proregenerative microenvironment for wound tissue. @*METHODS@#Based on the communication between cells, in this study, bone marrow mesenchymal stem cells (BMSCs) and hair follicle stem cells (HFSCs) were cocultured to fabricate a composite cell sheet (H/M–CS) for the treatment of fullthickness skin wounds in mice. @*RESULTS@#Experiments confirmed that there is cell–cell communication between BMSCs and HFSCs, which enhances the cell proliferation and migration abilities of both cell types. Cell–cell talk also upregulates the gene expression of proangiogenic-related cytokines in BMSCs and pro-hair follicle-related cytokines in HFSCs, as well as causing changes in the properties of secreted extracellular matrix components. @*CONCLUSIONS@#Therefore, the composite cell sheet is more conducive for cutaneous wound healing and promoting the regeneration of blood vessels and hair follicles.
ABSTRACT
BACKGROUND@#This study aims to clarify the mechanism underlying dental pulp cells-extracellular vesicles (DPC–EVs) carrying runt-related transcription factor 3 (RUNX3) in mediating odontogenic differentiation of dental pulp stem cells (DPSCs) with the involvement of miR-30a-5p-regulated NOTCH1. @*METHODS@#Extracellular vesicles (EVs) were isolated from human DPSCs, and identified using transmission electron microscopy, and nanoparticle tracking analysis. PBS, EVs, or EV inhibitor GW4869 was added to DPSCs for co-culture, whilst odontogenic differentiation was assessed in terms of ratio of mineralized nodules and expression odontoblast differentiation markers. Dual luciferase reporter gene assay and chromatin immunoprecipitation for binding relation among RUNX3, miR-30a-5p and NOTCH1were employed to evaluate their roles in odontogenic differentiation was determined.Animal experiment was established to confirm the effect of DPC-EVs-loaded RUNX3 on dental pulp. @*RESULTS@#In vitro finding demonstrated that EVs delivered RUNX3 to DPSCs, thereby activated miR-30a-5p expression and inhibited NOTCH1 expression, which was reversed by addition of GW4869. RUNX3 upregulation promoted miR-30a-5p while miR-30a-5p targeted and inhibited NOTCH1. Silencing of RUNX3 in EVs decreased expression of those differentiation markers, downregulated miR-30a-5p and upregulated NOTCH1. @*CONCLUSION@#DPSC-EVs can carry RUNX3 to the DPSCs, promote the transcription of miR-30a-5p, and then inhibit the expression of NOTCH1, and finally promote the odontogenic differentiation of DPSCs.
ABSTRACT
Parkinson's disease (PD) is a chronic neurodegenerative disease. At present, levodopa and other drugs are mainly used for dopamine supplementation therapy. However, the absorption of levodopa in the gastrointestinal tract is unstable and its half-life is short, and long-term use of levodopa will lead to the end-of-dose deterioration, dyskinesia, the "ON-OFF" phenomenon and other symptoms. Therefore, new preparations need to be developed to improve drug efficacy, reduce side effects or improve compliance of patients. Based on the above clinical needs, this review briefly introduced the preparation modification strategies for the treatment of PD through case analysis, in order to provide references for the research and development of related preparations.
ABSTRACT
Bioactive compounds derived from herbal medicinal plants modulate various therapeutic targets and signaling pathways associated with cardiovascular diseases (CVDs), the world's primary cause of death. Ginkgo biloba, a well-known traditional Chinese medicine with notable cardiovascular actions, has been used as a cardio- and cerebrovascular therapeutic drug and nutraceutical in Asian countries for centuries. Preclinical studies have shown that ginkgolide B, a bioactive component in Ginkgo biloba, can ameliorate atherosclerosis in cultured vascular cells and disease models. Of clinical relevance, several clinical trials are ongoing or being completed to examine the efficacy and safety of ginkgolide B-related drug preparations in the prevention of cerebrovascular diseases, such as ischemia stroke. Here, we present a comprehensive review of the pharmacological activities, pharmacokinetic characteristics, and mechanisms of action of ginkgolide B in atherosclerosis prevention and therapy. We highlight new molecular targets of ginkgolide B, including nicotinamide adenine dinucleotide phosphate oxidases (NADPH oxidase), lectin-like oxidized LDL receptor-1 (LOX-1), sirtuin 1 (SIRT1), platelet-activating factor (PAF), proprotein convertase subtilisin/kexin type 9 (PCSK9) and others. Finally, we provide an overview and discussion of the therapeutic potential of ginkgolide B and highlight the future perspective of developing ginkgolide B as an effective therapeutic agent for treating atherosclerosis.
ABSTRACT
ObjectiveTo analyze the relationship of the static single-leg stance balance with ankle muscles strength and position sense in individuals with functional ankle instability (FAI). MethodsFrom March to May, 2023, 44 FAI individuals were recruited in Hebei Normal University, and the maximum isokinetic muscle strength (60°/s and 180°/s) and position sense as ankle flexion, extension, inversion and eversion were measured using isokinetic dynamometer; while the center of pressure (COP) sway distance and envelope area were measured as static single-leg stance with eyes open or closed using three-dimensional force plate. ResultsThe maximum isokinetic torque as ankle eversion at 180°/s correlated with the COP anterior-posterior sway distance with eyes closed (r = -0.378, P < 0.05). ConclusionExplosive ankle eversion strength is related with the balance in static single-leg stance, which may help to evaluate and intervent the ankle function of FAI individuals.
ABSTRACT
The paper presents professor WU Han-qing's experience in treatment of lumbar disc herniation (LDH) with "sinew-bone three needling technique" of Chinese medicine. Based on the theory of meridian sinew, the points are located by "three-pass method" in terms of the distribution of meridian sinew and syndrome/pattern differentiation. The cord-like muscles and adhesion are relieved by relaxing technique to work directly on the affected sites and alleviate the local compression to the nerve root. The needle technique is operated flexibly according to the affected regions involved, due to which, the needling sensation is increased while the safety ensured. As a result, the meridian qi is enhanced, the mind and qi circulation is regulated; and the clinical effect is improved.

OBJECTIVE@#To validate the effectiveness of a novel comprehensive classification for intertrochanteric fracture (ITF).@*METHODS@#The study included 616 patients with ITF, including 279 males (45.29%) and 337 females (54.71%); the age ranged from 23 to 100 years, with an average of 72.5 years. Two orthopaedic residents (observers Ⅰ and Ⅱ) and two senior orthopaedic surgeons (observers Ⅲ and Ⅳ) were selected to classify the CT imaging data of 616 patients in a random order by using the AO/Orthopaedic Trauma Association (AO/OTA) classification of 1996/2007 edition, the AO/OTA classification of 2018 edition, and the novel comprehensive classification method at an interval of 1 month. Kappa consistency test was used to evaluate the intra-observer and inter-observer consistency of the three ITF classification systems.@*RESULTS@#The inter-observer consistency of the three classification systems evaluated by 4 observers twice showed that the 3 classification systems had strong inter-observer consistency. Among them, the κ value of the novel comprehensive classification was higher than that of the AO/OTA classification of 1996/2007 edition and 2018 edition, and the experience of observers had a certain impact on the classification results, and the inter-observer consistency of orthopaedic residents was slightly better than that of senior orthopaedic surgeons. The intra-observer consistency of two evaluations of three classification systems by 4 observers showed that the consistency of the novel comprehensive classification was better for the other 3 observers, except that the consistency of observer Ⅳ in the AO/OTA classification of 2018 version was slightly higher than that of the novel comprehensive classification. The results showed that the novel comprehensive classification has higher repeatability, and the intra-observer consistency of senior orthopaedic surgeons was better than that of orthopaedic residents.@*CONCLUSION@#The novel comprehensive classification system has good intra- and inter-observer consistency, and has high validity in the classification of CT images of ITF patients; the experience of observers has a certain impact on the results of the three classification systems, and those with more experiences have higher intra-observer consistency.
