Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

【Objective】 To explore the effect of intelligent closed-loop mobile nursing management system in quality management of blood transfusion. 【Methods】 The mobile nursing system and the cold chain management system of our hospital were integrated to realize intelligent closed-loop management of blood transfusion. After consulting medical records, 789 blood recipients, admitted to the Department of Hematology of our hospital from January to December 2017 (before the implementation of closed-loop management), were selected as the control group, and 836 blood recipients, admitted during January to December 2018 (after the implementation of closed-loop management), were selected as the observation group. A self-designed blood transfusion standard management checklist was adopted, with the number of standard execution items as the numerator and the total number of checked items as the denominator to obtain the standard implementation rate. The checking rate of blood sample collection, blood transfusion rate within 30 min after blood issuing, the execution rate of double check specification and inspection specification, the completion rate of RBCs transfusion within 4 h and qualified rate of blood transfusion nursing record before and after the implementation of closed-loop management were compared by chi-square test or Fisher's exact probability method to evaluate the efficacy of blood quality management improvement. A total of 8 head nurses from clinical departments (Hematology Department, Cardiac Surgery Department, Operating Room, Comprehensive ICU) involved in blood transfusion were selected for semi-structured interviews. The interviews focused on the effect of intelligent closed-loop mobile nursing information system in quality management of clinical blood use, and the results of the interviews were analyzed. 【Results】 The double check execution rate of blood transfusion, the checking rate of blood sample collection specification, the transfusion rate within 30 min after blood issuing, the execution rate of blood transfusion inspection, the completion rate of RBCs transfusion within 4 h, the qualified rate of blood transfusion nursing record in the observation group and the control group after and before the implication of the intelligent closed-loop mobile nursing management system were 100%(836/836) vs 97.72%(771/789), 99.04%(828/836) vs 97.34%(768/789), 97.97%(819/836) vs 95.06%(750/789), 99.28%(830/836) vs 94.93%(712/789), 99.16%(829/836) vs 97.47%(769/789) and 100%(836/836) vs 89.73%(708/789), respectively, showing significant improvement (P < 0.05). The time spend on the record, summary and feedback of quality control results was significantly shortened. 【Conclusion】 The application of intelligent closed-loop mobile nursing management system in the quality management of clinical blood use can effectively improve the efficiency of blood transfusion, nursing quality and the safety of clinical blood use.

OBJECTIVETo find out and analyze differentially expressed miRNAs in the plasma of benzene exposed workers, and explore the potential roles of plasma miRNAs in the development of hematologic toxicity induced by benzene exposure.

METHODSBy individual matching, low blood cell group, unstable blood cell group and normal group of 10 benzene exposed workers in each group were taken as subjects. Microarray was used to find out differentially expressed miRNAs among three groups. Three miRNAs validated by real-time quantitative PCR. Target genes of 9 miRNAs with the high abundance and significant difference were predicted using Target scan, Picture and miRanda softwares. David 6.7 online platform was used to perform GO term enrichment and KEGG pathway analysis of those targets.

RESULTSMicroarray screened out that 138 miRNAs were differentially expressed. Three significant classes of differentially expressed miRNAs were found with the cluster analysis. The detected expressions of miR-638, let-7f-5p and miR-223-3p by relative RT-qPCR was consistent with the microarray date. Pathway analysis showed that the most enriched pathway was focal adhesion, with 6 potential functional targets, including SOS₂, VCL, CCND2, COL4A6, IGF1 and MAPK1.

CONCLUSIONWe have identified the plasma miRNA profile in benzene exposed workers, and further analysis indicates that focal adhesion-associated miRNAs play a potential role in hematologic toxicity induced by benzene exposure.

Objecfive To compare the clinical effectiveness of three different fixation methods for peripherally inserted central catheter(PICC).Methods Totally 120 patients requiting PICCs were randomized into suture securement group(group A),tape securement group(group B),and sutureless adhesive-hacked device (StatIock)securement group(group C),with 40 patients in each group.Patients were followed up throughout their entire catheter course,and the securement effectiveness,catheter-related complications,risk of skin injury,and patients'satisfaction were observed.Results The rate of catheter migration without function loss in group B (57.5%)was significantly higherthan in group A(12.5%,P=0.000)and in group C(7.5%,P=0.000).Catheter dislodgment rate in group B(15.0%)was also significantly higher than group A(0,P=0.034)and group C(0,JP=0.034).Phlebitis documented during their catheter course in group B(25.0%)were more than in group A(7.5%,P=0.034)and in group C(5.0%,P=0.012).In addition,the rate of cellulitis in group A was significantly higher than group C(20.0%vs.2.5%,P=0.034).The rate of skin injury in group A 0.005).Nearly half of patients in group A (52.5%)complained irritation and/or pain at the sucure site,which was significantly higher than in other two groups ( both P = 0.000 ).The patients' satisfaction rate was significantly lower in group A (12.0% ) than in the other two groups ( both P = 0.000), documented highest in group C (90.0%) (group C vs.group B, P = 0.004).Conclusions The availability of sutureless adhesive-backed de vice StatLock provides an alternative for securement of PICCs.It performs as well as suture securement in catheterfixing.Meanwhile, it can prevent catheter-related complications such as migration and dislodgment Furthermore, it avoids skin injuries during catheter fixation or securement.

Objective To prospectively evaluate the value of diffusion-weighted imaging with background signal suppression (DWIBS) in the detection and diagnoses of metastatic cervical lymph nodes. Methods Twenty patients with head and neck squamous cell carcinomas underwent conventional MRI and DWIBS. The ADC values were measured and compared between metastatic and benign lymph nodes. The abilities of DWIBS and conventional MRI in the evaluation of metastatic cervical lymph nodes were compared. Results Conventional MRI demonstrated 101 lymph nodes, in which 58 were diagnosed as metastatic nodes. When MRI criteria were used for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity, accuracy, positive and negative predictive value were 78% (47/60), 81%(44/54), 80% (91/114), 82% (47/57) and 77% (44/57), respectively. The mean ADC values of metastatic nodes (n =60) and benign nodes (n =54) were (0.945 ±0.122) × 10-3 mm2/s and (1. 210 ±0. 151 ) × 10-3 mm2/s ( t = - 10. 354 ,P ＜0. 01 ). When an ADC value of 1. 090 × 10 -3 mm2/s was used as the threshold for discrimination between metastatic and benign nodes, the obtained sensitivity, specificity,accuracy, positive and negative predictive value were 88% (53/60), 80% (43/54), 84% (96/114), 83%(53/64) and 86% (43/50), respectively. Conclusion DWIBS is helpful in diagnosing metastatic cervical lymph nodes of head and neck squamous cell carcinoma, and is superior to conventional MRI in their detection.

Objective To analysis the effect of axial loading to ADC value, FA of lumbar intervetebral discs. Methods Forty five patients with low back pain (age range, 25 to 54 years) were evaluated with MR T2WI, MR T1WI and diffusion tensor imaging (DTI) of the lumbar spine. Following axial loading with 40% to 50% body weight for 10 minutes, a repeat DTI was performed. DTI were obtained by using an echo-planar imaging ( EPI ) sequence, TE 89 ms, TR 2500 ms, b value of 400 s/mm2,6 noncollinear diffusion directions. Scan time was approximately 4 min 10 s. An isotropic ADC map, FA map and bo map were calculated from DTI sequence. The mean ADC value, FA prior to and following axialloading were analyzed with t test and Rank Sum test. Results Forty five patients with 225 discs were evaluated and 223 discs were included in the study except for 2 calcified discs. The Pfirrmann grading results were as following: 100 Grade Ⅱ , 48 Grade Ⅲ, 59 Grade Ⅳ, and 16 Grade Ⅴ. No significant difference existed in the mean ADC value before [ ( 1666 ± 252 ) × 10-3 mm2/s ] and after [ ( 1662 ± 253 ) ×10 -3 mm2/s ] axial loading ( Z = - 1.363, P ＞ 0.05 ), but the mean FA [ ( 301 ± 104 ) × 10 -3, ( 316 ±112) × 10-3 ] value increased ( Z = - 2.794, P ＜ 0.05 ). The paired-samples t test show that the mean ADC value [ ( 1685 ± 190) × 10-3 mm2/s, ( 1624 ± 180) × 10-3mm2/s] of Grade Ⅲ discs decreased after axial loading, t=3.513, P＜0. 05, Grade Ⅲ, Ⅳdiscs mean FA value [(300±87) ×10-3, (326±87) ×10-3 for Grade Ⅲ and (348 ±67) × 10-3, (351 ± 71 ) × 10-3 for Grade Ⅳ ] increased, t = - 2. 210,- 2.006, P ＜ 0.05. No significant difference existed in Grade Ⅱ , Ⅳ and Ⅴ discs ADC value, all the P ＞0.05. No significant difference existed in Grade Ⅱ and Ⅴ discs FA value, both the P ＞ 0.05. Conclusions Short time axial loading mainly affect the mildly degenerated discs, the ADC value decreases and the disc diffusion ability decreases. No obvious change in ADC value or disc diffusion ability existed in the normal and severely degenerated discs.
