Objective:To investigate the anatomical feasibility of the endoscopic transorbital approach (ETOA) to the orbital apex and lateral middle cranial fossa, to identify stable and recognizable surgical landmarks under endoscopic visualization, and to provide morphometric data for preoperative planning and intraoperative navigation.Methods:Stepwise anatomical dissection was performed on five formalin-fixed cadaveric heads and one fresh arterially injected cadaveric specimen to simulate the ETOA using a 0° endoscope. Key structures and their anatomical relationships were observed and recorded. Additionally, high-resolution CT scans of 50 adults were retrospectively analyzed. Three-dimensional reconstructions and measurements were performed using Mimics 17.0 software. Spatial validation was performed using 17 dry skulls to verify the consistency and reliability of osseous anatomical landmarks.Results:Cadaveric dissection identified the meningo-orbital band, superior orbital fissure, optic canal, foramen rotundum, and foramen ovale as reliable surgical landmarks for the ETOA. A topographic map of the surgical region was established based on the endoscopic view. CT measurements revealed the following distances (Mean±SD): the midpoint of the supraorbital rim to the foramen rotundum (57.31±3.59) mm and foramen ovale (71.46±3.42) mm; the lateral orbital rim to the lateral edge of the superior orbital fissure (37.38±2.52) mm; the distance from the superior orbital fissure to the optic canal (9.98±1.49) mm; and the distance from the anterior ethmoidal artery to the optic canal (19.98±2.05) mm. These measurements were consistent with dry skull data, indicating that these osseous landmarks had stable spatial relationships and were suitable for intraoperative localization.Conclusions:The ETOA provides favorable anatomical accessibility and clinical feasibility for lesions involving the orbital apex and lateral skull base. Key osseous structures demonstrate high identifiability and stable spatial relationships, serving as critical references for intraoperative navigation and preoperative pathway planning. The quantitative anatomical framework established in this study provides critical morphometric support for minimally invasive surgery targeting lesions in this region.

[Objective]The heightened expression of local immunoglobulins is a significant pathological characteristic of chronic rhinosinusitis with nasal polyps(CRSwNP),particularly in the Asian population.This study is centered on ex-ploring the association between MZB1 and the localized aggregation of immunoglobulins in Asian individuals with CRSwNP.[Methods]Nasal polyp tissues obtained from 40 CRSwNP patients and inferior turbinates from 6 healthy controls under-went examination for both mRNA and protein levels.The assessments were conducted using polymerase chain reaction,lu-minex,and immunohistochemical staining.Statistical analyses,including one-way Anova(ANOVA),independent sam-ples t-test,and Pearson's correlation analysis,were employed for comprehensive data evaluation.[Results]The mRNA ex-pression levels of MZB1(P<0.01)and HSP90B1(P<0.01)were significantly higher in type 2 CRSwNP patients com-pared with those in healthy controls.Immunohistochemical staining revealed a significant increase in MZB1 protein expres-sion in type 2 CRSwNP.MZB1 demonstrated correlation with the expression of immunoglobulin E in nasal polyp tissues(P<0.01,r=0.52).Additionally,MZB1correlated with the expression ofIL-5(P<0.05,r=0.4)and IL-13(P<0.05,r=0.44)in nasal polyp tissues.Furthermore,MZB1showed correlation with the number of eosinophils in nasal polyp tis-sues(P<0.05,r=0.72).[Conclusion]The expression of MZB1 is notably elevated in Asian CRSwNP,particularly in type 2 CRSwNP,when compared with controls.MZB1expression correlates significantly with high IgE expression and dis-ease severity in nasal polyp tissues.

Objective:To investigate the effect of 3D-printed customized flanged cup in hip revision with severe acetabular bone defects.Methods:Since February 2017, 10 cases of 3D-printed customized flanged cups were used in hip revision with severe acetabular bone defects, including 2 cases of Paprosky type IIIA and 8 cases of Paprosky type IIIB. There were 5 males and 5 females, mean age 73.6±8.1 yrs (range, 62-87 yrs), 5 left and 5 right cases. The preoperative thin-layer CT scan was preformed to reverse reconstruct digital pelvis. Five cases of one-piece flanged cups and 5 cases of decomposed flanged cups, including 3 cases of composite one-piece cups were designed by computer. The surgery was performed strictly according to the plan.Postoperative follow-up was performed to evaluate the Harris score. Operation time,intraoperative bleeding and other complications such as vascular and nerve injury, postoperative infection, and dislocation were counted. Pelvic X-ray was used to assess the height and horizontal position of the center of rotation and the stability of the prosthesis.Results:The surgical procedure was successful, with an average operative time of 147.9±48.3 min (range, 96-212 min) and an average intraoperative bleeding of 730.4±262.6 ml (range, 500-1 300 ml). The mean time of final follow-up was 40.8±18.7 months (range, 16-70 months) after surgery. At the last follow-up, the average Harris score was 83.80±6.73, with 4 cases excellent, 5 cases good, and 1 case fair. The excellent and good rate was 90%. The last Harris score was significantly higher than that before operation 28.60±8.40 ( t=16.84, P<0.001). The height of affected hip joint rotation center decreased from 46.24±7.74 mm before operation to 15.54±2.54 mm after operation with significant difference ( t=14.61, P<0.001). It was slightly higher than the opposite side (13.81±1.48 mm), which had no significant difference ( t=1.83, P=0.100). The horizontal distance of affected hip joint rotation center increased from 33.79±5.27 mm before operation to 40.53±4.50 mm after operation with significant difference ( t=3.62, P=0.006). It had no significant difference ( t=1.28, P=0.232) compared with the opposite side (38.54±3.46 mm). All incisions were healed in one stage without infection, vascular or nerve injury. During the following-up, all prostheses were in satisfied position without loosening, dislocation or screw breaks. Conclusion:Digitally assisted 3D-printed flanged cups can be used in hip revision with severe acetabular bone defect. It can not only improve hip joint function, but also restore the acetabular rotation center and the prosthesis stability, which can achieve good early and mid-term effect.

With the increase of obesity and type 2 diabetes, gestational diabetes mellitus (GDM) is growing public health problem worldwide. GDM is one of the most ubiquitous diseases affecting pregnancy outcomes in perinatal women, which increases the incidence of adverse outcomes such as miscarriage, macrosomia, premature birth and stillbirth. Non-coding RNA (ncRNA) plays an important role in regulating the occurrence and development of GDM, and it is also related to the occurrence of complications of GDM. NcRNA is a type of RNA that don't encode proteins, including long non-coding RNA (LncRNA), microRNA (miRNA) and circular RNA (circRNA). More and more studies show ncRNA contains abundant information. This review discusses the relationship between three kinds of ncRNA and GDM, in aim to provide theoretical basis for further research on gestational diabetes.

Objective:To establish core items of nutrition literacy for general population in China.Methods:The framework system and preliminary items of nutrition literacy were established through literature review and experts′ consultation. Content validity test was used to determine the nutrition literacy item. Thirteen experts in the field of human nutrition, health education and nutrition and diseases were invited to score the importance of each nutrition literacy item via Email.
