  • Transconjunctival lower eyelid blepharoplasty with “super released” orbital fat in correction of tear trough and palpebromalar groove depression

    Objective To investigate effectiveness of transconjunctival lower eyelid blepharoplasty with “super released” orbital fat in correction of lower eyelid pouch protrusion and tear trough and palpebromalar groove depression. Methods A clinical data of 82 patients (164 sides) with lower eyelid pouch protrusion and tear trough and palpebromalar groove depression, who met the selection criteria between September 2021 and May 2022, was retrospectively analyzed. Of the included patients, 3 were males and 79 were females, with an average age of 34.5 years (range, 22-46 years). All patients had varying degrees of eyelid pouch protrusion and tear trough and palpebromalar groove depression. The deformities were graded by the Barton grading system as gradeⅠ in 64 sides, grade Ⅱ in 72 sides, and grade Ⅲ in 28 sides. The orbital fat transpositions were performed through the lower eyelid conjunctival approach. The membrane surrounding the orbital fat was completely released, allowing the orbital fat to fully herniate until the herniated orbital fat did not retract significantly in a resting and relaxed state, which is regarded as the “super released” standard. The released fat strip was spread into the anterior zygomatic space and the anterior maxillary space, and percutaneous fixed to the middle face. The suture that penetrates the skin was externally fixed by adhesive tape pasting without knotted. Results There were 3 sides with chemosis after operation, 1 side with facial skin numbness, 1 side with mild lower eyelid retraction at the early stage after operation, and 5 sides with slight pouch residue. No hematoma, infection, or diplopia occurred. All patients were followed up 4-8 months, with an average of 6.2 months. The eyelid pouch protrusion, tear trough, and palpebromalar groove depression were significantly corrected. At last follow-up, the deformity was graded by Barton grading system as grade 0 in 158 sides and grade Ⅰ in 6 sides, with a significant difference compared to the preoperative score (P<0.001). Patient’s self-evaluation satisfaction reached very satisfied in 67 cases (81.7%), satisfied in 10 cases (12.2%), generally satisfied in 4 cases (4.8%), and dissatisfied in 1 case (1.2%). Conclusion The “super released” orbital fat can effectively prevent the retraction of orbital fat, reduce the probability of residual or recurrence of eyelid pouches, and improve the correction effect.

  • An Epidemiology Study on Child Behavior Problems among High-Grade Primary School Students in Chongqing Urban Area

    Objective To explore the prevalence and related factors of behavior problems among the high-grade primary school students (in Grade 4 to Grade 6) in Chongqing urban area. Methods By means of cross-sectional survey, a total of 3 137 high-grade primary school students in Chongqing urban area were investigated with Child Behavior Checklist (CBCL, version for parents) and self-designed basic information questionnaire. Results The relevance ratio of behavior problems was 27.26%. The univariate analysis revealed that type of school, grade, residential and family environment, and parental attitude toward children had effects on children’s behavior problems with significance difference (Plt;0.05). The stepwise regression revealed that grade, educational level of father, healthy conditions of parents, family structure, academic performance and parental attitude toward children were the independent and main influencing factors (Plt;0.05). Conclusion The relevance ratio of behavior problems among high-grade primary school students in Chongqing urban area is much higher, which is related to the following factors: family situation, parental attitude toward children, social and school environment. It indicates that the status of children’s mental heath is not optimistic in Chongqing urban area. Comprehensive measures combining family, school with psychologist should be taken to reduce the prevalence of behavioral problems.

  • Effect of resveratrol on high mobility group box-1 protein signaling pathway in cartilage endplate degeneration caused by inflammation

    Objective To investigate the effect of resveratrol (RES) on inflammation-induced cartilage endplate (CEP) degeneration, and its regulatory mechanism on high mobility group box-1 protein (HMGB1) signaling pathway. Methods The intervertebral CEP cells of Sprague Dawley (SD) rats aged 3 weeks were extracted and identified by toluidine blue staining and immunofluorescence staining of rabbit anti-rat collagen type Ⅱ. The cell counting kit 8 (CCK-8) method was used to screen the optimal concentration of RES on intervertebral CEP cells. Gene chip analysis was used to determine the target of RES on intervertebral CEP cells. Interleukin 1β (IL-1β) was used to construct the intervertebral CEP cell degeneration model caused by inflammation and the 7-8-week-old SD rat intervertebral disc degeneration model, and pcDNA3.1-HMGB1 (pcDNA3.1) was used as the control of RES effect. Flow cytometry and TUNEL staining were used to detect the apoptotic rate of intervertebral CEP cells and rat intervertebral disc tissue cells, respectively. ELISA kit was used to detect the content of interleukin 10 (IL-10) and tumor necrosis factor α (TNF-α) in the cell supernatant and rat serum. Western blot was used to detect the expressions of HMGB1, extracellular signal-regulated protein kinase (ERK), phosphorylated ERK (p-ERK), B cell lymphoma/leukemia 2 gene (Bcl-2), and Bcl-2-associated X protein (Bax). ResultsThe extracted cells were identified as rat intervertebral CEP cells. CCK-8 method screened out the highest activity of intervertebral CEP cells treated with 30 μmol/L RES. The gene chip analysis confirmed that the HMGB1-ERK signal was the target of RES. Both cell experiments and animal experiments showed that RES treatment can significantly down-regulate the apoptosis rate of intervertebral CEP cells, inhibit the release of TNF-α, and increase the content of IL-10; and down-regulate the expressions of HMGB1, p-ERK, and Bax, and increase Bcl-2; and pcDNA3.1 could partially reverse these effects of RES, and the differences were all significant (P<0.05). ConclusionRES can significantly inhibit the apoptosis of intervertebral CEP cells induced by inflammation, which is related to inhibiting the expression of HMGB1.
