Ethmo-maxillary bone buttress (EMBB) is a special complex bone structure in the interface between the internal wall and inferior wall of the orbit, which plays a vital role in maintaining the stability of the orbit, ethmoidal sinus and maxillary sinus.Although the incidence of compound fractures in orbital blowout fractures is lower than that of single orbital wall fractures, they have more obvious clinical symptoms such as enophthalmia and binocular diplopia.The mechanism of EMBB may be more supportive of the orbital floor compression theory, that is, the external force will lead to torn periostum and bone seam separation at the ethmoidomaxillary suture, and the orbital contents will form a funnel-like hernia due to extrusion and gravity.Or the extrusion results in the fracture and displacement of the orbital lamina of ethmoid bone, the upper wall of the maxilla and the ethmoidomaxillary plate, causing a large area of orbital wall collapse and obvious expansion of the orbital cavity.Recently, the study of orbital internal wall and inferior wall joint fracture has become a new hotspot, but research on the orbital blowout fracture involving ethmo-maxillary bone buttress is still in its infancy.The current orbital fracture repair technique can only restore the connection between the two orbital walls, and there is no surgical plan can overall recover EMBB's scaffolds role.Therefore, how to restore the scaffolds role of EMBB, and to regain the part of ostiomeatal complex in normal sinus drainage is the challenge we need to conquer.In this article, the anatomy and clinical characteristics of the supporting structure, fracture mechanism, and the research progress and prospect of surgical repair technique were reviewed.

Objective:To distinguish lung adenocarcinoma (ADC) from squamous cell carcinoma (SCC) using 18F-fluorodeoxyglucose (FDG) PET-based radiomic features. Methods:A retrospective analysis was performed in 182 patients (109 males, 73 females, age (59.0±8.3) years) with non-small cell lung cancer (NSCLC) who underwent 18F-FDG PET/CT scan between January 2018 and December 2019 in Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology. All patients had been diagnosed pathologically with lung ADC or SCC. The patients were divided into a training set ( n=91) and a validation set ( n=91) using simple random sampling method. Radiomic features were extracted from the PET images of segmented tumors using the Python package. The minimum redundancy maximum relevance feature selection algorithm and least absolute shrinkage and selection operator were employed to select informative and non-redundant features, and a radiomics signature score (rad-score) was developed. Differences of rad-score between groups were compared by Mann-Whitney U test. Multivariate logistic regression was applied to select the important factors. A combined model was constructed based on the clinical variable and radiomics signature. The predictive performance of models was analyzed and compared using receiver operating characteristic (ROC) curves and Delong test. Results:Four radiomic features, namely HHL_first order_maximum, LHL_first order_entropy, HHH_ gray level dependence matrix_large dependence high gray level emphasis (GLDM_LDHGLE), HHL_GLDM_LDHGLE (H/L represent the high/low pass filter) were selected to build the rad-score. The rad-score showed a significant ability to discriminate between different histological subtypes in the two sets(training set: -1.30(-1.70, -1.04) vs -0.60 (-1.11, 0.20), z=-4.61, P<0.001); validation set: -1.31(-1.66, -0.96) vs -0.73(-1.02, -0.24), z=-4.76, P<0.001). The area under the curve (AUC) of the rad-score were equal to 0.815 (95% CI: 0.723-0.906) in the training set, and 0.813 (95% CI: 0.726-0.901) in the validation set, respectively, which were larger than those of the clinical variables (smoking had the best prediction performance, training set: 0.721 (95% CI: 0.617-0.810), validation set: 0.726 (95% CI: 0.623-0.814)), however, the difference was not significant ( z values: 1.319, 1.324, both P>0.05). When the clinical variable (smoking) and radiomics signature were combined, the complex model showed a better performance in the classification of histological subtypes, with the AUC increased to 0.862 (95% CI: 0.785-0.940; sensitivity: 88.00%(22/25), specificity: 72.73%(48/66)) in the training set and 0.854 (95% CI: 0.776-0.933; sensitivity: 75.00%(21/28), specificity: 84.13%(53/63)) in the validation set. The AUC values were significantly higher than those of the clinical variable (smoking; training set: z=3.257, P<0.001; validation set: z=3.872, P<0.001). Conclusion:Individualized diagnosis model incorporating with smoking and radiomics signature can help differentiate lung cancer subtypes in a non-invasive, repeatable modality.

Objective To probe the transplantation of skeletal muscle satellite cells of new-born rats for repairing skeletal muscle contusions. Methods Thirty-six Sprague-Dawley adult rats were separated at random into experimental and control groups (including a normal saline control group and a normal control group). Contusions were created on the left hind legs of rats in the experimental group. The cells were cultured and antibodies were identified through immunocytochemical staining and fluorescence labeling. In the experimental group, 0.2 ml of a muscle satellite cell suspension was slowly injected into the medial and lateral heads of the right calf gastrocnemius. The normal saline control group was injected with an equal volume of normal saline solution at the same sites. On the 5th, 10th and 15th day after the operation, EMG wave-amplitude and wave-width were recorded. The recovery rate of the muscle's wet weight and the gray value of a muscle fiber transverse section were determined.Two-factors analysis of variance was performed on the data. Results Before transplantation the muscle satellite cells were bright red after staining and their nuclei were blue after fluorescence labeling. After the operation the number of cells fluorescing and the strength of the fluorescence gradually decreased. The transplanted cells formed myotubes, melted into the muscle tissue and gradually took part in the restoration. The stained muscle satellite cell nuclei were free in intercellular space and melted into the basement membrane gradually. The outlines of the muscle tissue became progressively clearer. EMGs showed the fibrillation potentials as well as positive sharp waves reduced, but they too tended to become similar to those from the normal side. Restoration of EMG wave-amplitude and wave-width in the experimental group was better than in the saline control group and close to those in the normalcontrol group. The gray value of the muscle fiber transverse section area under HE staining was significantly lower at the 5th day post transplantation in both the experimental group and the saline control group than in the normal control group. At the 10th and 15th days post transplantation, the average gray value in the experimental group had increased significantly more than in the saline control group, and it was close to the normal control group average. In the experimental group the recovery rate of muscle wet weight was close to 1, but in the saline control group it was less than 1. Conclusions Transplanting skeletal muscle satellite cells of new-born rats can produce evident effects in renovating injured muscles.

The afferent connections to the periaqueductal gray in the rat were examined by means of retrograde axonal transport method using horseradish peroxidase (HRP).The microinjection syringe needle or micro-electrophoretic pipette was inserted stereotaxically by an oblique approach through the cerebellum. HRP was introduced into the dorsal, lateral, ventrolateral areas of periaqueductal gray or periventricular gray of ventriculus Ⅲ at posterior commissure level respectively.The results were as follows:1. Injections of HRP in the dorsal area of periaqueductal gray(PAG).Numerous labeled cells were consistently found in the paraventricular nucleus, dorsomedial and ventromedial hypothalamic nuclei, posterior hypothalamic nucleus, medial mamillary nucleus, zona incerta, lateral and ventral nuclei of periaqueductal gray, superior colliculus, inferior colliculus, dorsal raphe nucleus and periventricular gray of ventriculus Ⅳ. In some cases, a smaller number of cells was found in the zona reticulata of the substantia nigra, and lateral hypothalamic nucleus. In one case, the enzyme was injected into the dorsal area of PAG, which diffused to the superior and inferior colliculi, resulted in labeling of Forel's field and reticular nucleus of thalamus.2. Injection of HRP in the lateral area of PAG.HRP-positive cells were observed within the bed nucleus of the stria terminalis, paraventricular nucleus, anterior hypothalamic nucleus, ventro-medial hypothalamic nucleus, medial thalamic nucleus, nucleus interstitialis magnocellularis, commissural posteriors, zona incerta, ventral nucleus of PAG, zona reticulata of substantia nigra, formatio reticularis of mesencephalon, dorsal raphe nucleus, and periventricular gray of ventriculus Ⅲ and Ⅳ. In some cases, a small number of cells was found in the supraoptic nucleus, superior and inferior colliculi.3. Injection of HRP in the ventrolateral area of PAG.In all cases the greatest number of HRP-positive neurons was shown in the supraoptic nucleus, paraventricular nucleus, periventricular gray of ventriculus Ⅲ, lateral nucleus of PAG, zona reticulata of substantia nigra, dorsal raphe nucleus and locus coeruleus. The labeled cells were mainly located ipsilaterally. But the labeling of supraoptic nucleus was observed bilaterally. In one case the enzyme diffused to the reticular formation, a smaller number of cells was found in nucleus cuneifomis and mesencephalic reticular formation of more caudal position.4. Injection of HRP in the periventricular gray of ventriculus Ⅲ.Following the injections of HRP in the periventricular gray of ventriculus Ⅲ, numerous HRP-positive cells were consistently observed in the bed nucleus of the stria terminalis, supraoptic nucleus, paraventricular nucleus, ventromedial nucleus of hypothalamus, medial nucleus pars medialis of thalamus, zona incerta, ventral nucleus of PAG, zona reticulata of substantia nigra, dorsal raphe nucleus and locus coeruleus.
