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 regulatory effect of exosomes derived from healthy human adipose stem cells (ADSC) on the fibrosis of localized scleroderma fibroblasts (LSFs) in vitro. Methods:From January 2021 to January 2022, fat from 10 healthy donors in Department of Plastic Surgery, Peking Union Medical College Hospital, Chinese Academy of Medical Sciences was collected by liposuction. Adipose stem cells were isolated and cultured in vitro, and exosomes (ADSC-Exo) were collected. Fibroblasts were isolated from skin tissue of 15 patients with localized scleroderma during the same period and cultured in vitro. Induced differentiation and staining, nanoparticle tracking analysis, transmission electron microscopy, PKH26 staining and Western blotting were used to identify ADSC and their exosomes. The effect of ADSC on the expression of fibrosis markers [collagen Ⅰ, collagen Ⅲ, α-smooth muscle actin (α-SMA)] in LSFs through its exosomes was examined by extracellular vesicle secretion inhibition assay. The proliferation and migration abilities of LSFs treated with ADSC-Exo were tested by CCK-8 method and scratch test. Real-time quantitative PCR, immunofluorescence staining and Western blotting were used to detect the expression levels of collagen Ⅰ, collagen Ⅲ, α-SMA, transforming growth factor β (TGF-β) and p-Smad2/3 in LSFs. Independent sample t-test was used to compare between the two groups. One-way ANOVA was used for multi-group comparison, and SNK- q test was used for pairwise comparison. Results:ADSC and LSFs were successfully isolated and cultured in vitro, and ADSC-Exo was extracted. Extracellular vesicle secretion inhibition assay demonstrated that ADSC decreased fibrotic markers of LSFs by secreting extracellular vesicles. Results of CCK-8 and scratch test showed that the proliferation and migration ability of LSFs was decreased by ADSC-Exo treatment. The results of real-time quantitative PCR, immunofluorescence staining and Western blotting showed that compared with the control group, the expressions of collagen Ⅰ, α-SMA, TGF-β and p-Smad 2/3 in the ADSC-Exo treatment group were significantly decreased. Conclusion:In vitro, ADSC-Exo can affect the biological behavior and reduce the expression of fibrosis markers in LSFs by inhibiting the TGF-β/Smad pathway.

Objective To investigate visual impairment students' quality of life and its influencing factors in Braille learning class at Quanzhou Special School. Methods November, 2020, 52 students (aged seven to 26) with the best corrected distance visual acuity of the better eye above 0.02 were investigated with near visual acuity, contrast sensitivity and Chinese-version Low Vision Quality of Life Questionnaire (CLVQOL). The subjects were divided into second grade blindness group, first grade low vision group and second grade low vision group according to the best corrected distance visual acuity of the better eye. Results There were significant differences in distance visual acuity (Z = 45.671, P < 0.001), near visual acuity (Z = 24.972, P < 0.001), and contrast sensitivity (CS) ( Z = 13.285, P = 0.001) among three groups. There was a correlation between near visual acuity and distance visual acuity (r = 0.74, P < 0.001), CS to distance visual acuity (r = -0.58, P < 0.001) and near visual acuity (r = -0.57, P < 0.001), score of CLVQOL and CS (r = 0.44, P < 0.001). There were significant differences in the total score (Z = 10.145, P = 0.006), distance visual acuity subscale (Z = 13.586, P = 0.001), psychological adjustment subscale (Z = 7.824, P = 0.020), reading and fine work subscale (Z = 7.923, P = 0.019) of CLVQOL among the three groups. Conclusion Quality of life is different with the visual impairment for students in special school, especially the distance visual acuity, psychological adjustment and fine reading. CS correlates to the quality of life of visually impaired students, which needs to be a part of evaluation of visual function.

Objective:To evaluate the therapeutic effect of electroacupuncture on acute gastrointestinal injury (AGI) in patients with severe traumatic brain injury (sTBI).Methods:A prospective randomized controlled trial was conducted. 126 consecutively hospitalized patients with AGI after sTBI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Zhejiang University of Traditional Chinese Medicine from January 2018 to December 2019 were enrolled. The patients were divided into observation group and control group by random number table. All the patients of two groups were given conventional treatment of western medicine for consecutive 7 days, including the treatments of primary diseases, indwelling nasogastric tube to extract gastric contents every 6 hours to determine gastric residual volume (GRV). When vital signs were basically stable, enteral nutrition (EN) was implemented and EN feeding amount and speed were adjusted according to GRV. On the basis of conventional western medicine treatment, the observation group was treated with electroacupuncture at Zusanli, Tianshu, Shangjuxu, Xiajuxu and Zhongwan, once in the morning and once in the evening, 30 minutes each time. The gastrointestinal function parameters including intra-abdominal pressure (IAP), serum diamine oxidase (DAO) and gastrointestinal failure (GIF) scores were observed before treatment and at day 3 and day 7 of treatment. The incidence of ICU hospital-acquired pneumonia (HAP-ICU), duration of mechanical ventilation (MV), length of ICU stay, 28-day mortality and adverse reactions of electroacupuncture were also observed in the two groups. Kaplan-Meier method was used for 28-day survival analysis.Results:During the 7-day treatment and observation, 26 cases of 126 patients withdrew from the study, and 100 cases were actually enrolled, 50 cases in the observation group and 50 cases in the control group. IAP and DAO at day 3 of treatment in both groups were significantly lower than those before treatment [control group: IAP (cmH 2O, 1 cmH 2O = 0.098 kPa) was 13.75±2.76 vs. 18.11±3.97, DAO (U/L) was 129.88±24.81 vs. 158.01±22.64; observation group: IAP (cmH 2O) was 13.56±2.19 vs. 18.50±3.54, DAO (U/L) was 129.11±29.32 vs. 159.36±28.65; all P < 0.01]. The gastrointestinal function parameters of the two groups improved gradually with the extension of treatment time, and the IAP, DAO and GIF scores at day 7 of treatment in the observation group were significantly lower than those in the control group [IAP (cmH 2O): 11.28±3.61 vs. 12.68±3.23, DAO (U/L): 49.69±17.56 vs. 57.27±20.15, GIF score: 2.02±0.74 vs. 2.40±0.70, all P < 0.05). The duration of MV and the length of ICU stay in the observation group were significantly shorter than those in the control group [duration of MV (days): 15.72±4.60 vs. 18.08±4.54, length of ICU stay (days): 16.76±4.68 vs. 19.26±5.42, both P < 0.05], and the incidence of ICU-HAP and 28-day mortality were significantly lowered (12.0% vs. 30.0%, 22.0% vs. 32.0%, both P < 0.05). Survival analysis showed that the 28-day cumulative survival rate in the observation group was significantly higher than that in the control group (86.4% vs. 76.1%; Log-Rank test: χ 2 = 37.954, P < 0.001). The patients in the observation group had no significant adverse reaction of electroacupuncture treatment. Conclusion:Electroacupuncture at corresponding acupoints can effectively improve gastrointestinal function in patients with AGI after sTBI, which is beneficial to shortening the length of ICU stay, promoting the recovery of the patients, and reducing the 28-day mortality.

Objective: To explore the success rate and safety of axillary venipuncture catheterization with ultrasound localization and homologous surface localization (Magney). Method: A total of 80 patients were enrolled in the EICU from January 2017 to September 2018. They were randomly assigned to the Magney method (n=35) and the ultrasound-guided method (n=45). The number of successful punctures, success rate and complications were recorded. Results: Compared with ultrasound-guided method, the one-time success rate (25.7% vs 68.9%, P<0.01), puncture greater than 2 times (34.3% vs 11.1%, P=0.012), and total success rate (82.9% vs 100%, P=0.004) in Magney method were significantly different. Both of the two puncture methods were mis-invasive, and the difference was not statistically significant. In Magney method 2 patients occurred hematoma and 1 patient brachial plexus injury, but no infection occurred within 48 h. While no such occurrence was found in ultrasound-guided method. Conclusion Ultrasound-guided method axillary venipuncture is a safe and effective method of central venous catheterization, which has higher success rate and safety than Magney method.

Objective: To compare the effects of various interventions on the incidence of central line-associated bloodstream infection (CLABSI) . Methods: The clinical data of 218 patients with central venous catheterization were retrospectively analyzed. Infected patients were treated as CLABSI group and non-infected patients as control group. Results: Of the 218 patients, 24 patients were developed CLABSI. There was no significant difference in sex, age, primary infection status and puncture site between CLABSI group and control group. Univariate analysis showed that axillary vein puncture could significantly reduce the incidence of CLABSI (P=0.028), and the infection rate of axillary vein puncture per 1000 days under B-ultrasound was significantly reduced by 0.93‰. The average indwelling days of deep venous catheter in patients with pulse puncture were significantly longer than those in other groups (47.32 days vs 19.90 days). The average indwelling days in patients with axillary vein puncture positioned by B ultrasound were longer than those in patients with other parts of vein puncture positioned by B ultrasound (P < 0.05). Logistic multiple regression analysis showed that the main risk factors for CLABSI were anatomically located puncture (P = 0.031) and non-axillary venous catheterization (P = 0.068). Conclusions Choosing axillary vein as the position of deep venous catheterization and using ultrasound-guided central venous puncture can reduce the incidence of CLABSI and prolong the average catheterization time.

Objective To discuss the influence of Tanshinone ⅡA on the tight junction protein of intestinal mucosal epithelial cells in rat severe septic models. Methods Seventy-five Sprague-Dawley (SD) rats were randomly divided into sham operation group, model group and Tanshinone ⅡA injection high (20 mg/kg), medium (10 mg/kg) and low (5 mg/kg) dose groups, each group 15 rats. Sepsis rat models were established by cecal ligation and puncture (CLP) method, in sham operation group, only switched abdominal surgery was performed without CLP. In Tanshinone ⅡA injection groups, different doses of Tanshinone ⅡA were injected intraperitoneally after modeling for 10 minutes and 6 hours; in sham operation and model groups, equal volume of normal saline was injected intraperitoneally at the same times as above. After operation, 3 L/kg of normal saline was injected into the caudal vein in all rats for fluid resuscitation.Twelve hours after operation, the rats were killed, the abdominal lymph nodes, liver, spleen and kidney tissues were taken for bacterial culture and calculating the rate of bacterial translocation; under microscope, the histopathological changes of ileum mucosal tissues were examined and Chiu scoring was carried out; TdT-mediated dUTP nick end labeling (TUNEL) was applied to detect the ileum mucosal epithelial cell apoptosis and calculating the index (AI);fluorescence immunoassay and Western Blot methods were used to measure the contents and protein expression levels of tight junction protein, junctional adhesion molecule-1 (JAM), Claudin-1, Zonula occludens-1 (ZO-1), Occludin, c-Fos and Tryptase. Results ① In bacterial cultures of abdominal lymph node, liver, spleen and kidney, the positive rate of mesenteric lymph node was the highest, followed by liver and spleen, mainly Escherichia coli, Proteus mirabilis, etc. The highest positive rate of bacterial culture was in model group (38.8%), followed by low dose of Tanshinone ⅡA injection group (35.0%), and the lowest was 16.6% in high dose Tanshinone ⅡA injection group, the differences being statistically significant in comparisons between any pair of groups (all P < 0.05). ② Pathological examination showed that the pathological changes of ileum mucosa were obvious and the Chiu score (4.17±0.98 vs. 0) and AI (11.70±2.87 vs. 2.17±0.80) in model group were significantly higher than those in sham group (all P < 0.05); with the increase of dosage of Tanshinone ⅡA injection, the pathological changes of rat ileum mucosa were improved gradually, the Chiu score and AI were decreased gradually, and the degrees of decrease in high dose Tanshinone ⅡA group were more significant than those in model group (Chiu score: 1.12±0.79 vs. 4.17±0.98, AI: 3.65±1.98 vs. 11.70±2.87, both P < 0.05).③ Immunofluorescence staining showed that the positive staining of protein JAM, ZO-1 and c-Fos were all green in color, Claudin-1, Occludin and Tryptase were all red in color, the localizations of all of them were in the cytoplasm, the protein expression of JAM, Claudin-1, ZO-1, Occludin from strong to weak in turn were Sham group, high, medium, low dose Tanshinone ⅡA group and model group, the expression of c-Fos, Tryptase from strong to weak in turn were model group, low, medium, high dose Tanshinone ⅡA group and Sham group. ④ Western Blot showed that the expressions of ileum tissue JAM, Claudin-1, ZO-1 and Occludin in model group were all significantly lower than those of the sham group, while the expressions of c-Fos, Tryptase were obviously higher than those of the sham group, with the increase of dosage of Tanshinone ⅡA, the expressions of JAM, Claudin-1, ZO-1 and Occludin were increased gradually and the protein expressions of c-Fos and Tryptase were gradually decreased, and the changes in high dosage group of Tanshinone ⅡA were more significant than those in low and moderate groups [JAM (gray value): 25.39±1.82 vs. 12.41±1.34, 19.45±1.66, Claudin-1 (gray value): 28.44±1.56 vs.17.26±1.46, 21.23±1.34, ZO-1 (gray value): 28.84±1.59 vs. 16.45±1.21, 24.22±1.46, Occludin (gray value): 25.49±1.63 vs. 13.34±1.45, 19.45±1.37, c-Fos (gray value):15.76±1.36 vs. 27.84±1.36, 21.22±1.73, Tryptase (gray value): 14.44±1.41 vs. 28.14±1.38, 22.32±1.57], all the above comparisons of different dosage groups were statistically significant (all P < 0.05). Conclusion Tanshinone ⅡA injection may improve intestinal wall structure and reduce bacterial translocation by improving the intestinal mucosal tight junction protein in sepsis model rats, and this effect is positively correlated to Tanshinone ⅡA dosage.
