Objective To investigate the effect of glaucocalyxin A(GLA)on neuroinflammation and the HMGB1-RAGE signaling pathway in rats with Alzheimer disease(AD).Methods Rats were given intracerebroventricular injec-tion of Aβ1-42 solution to establish a model of AD,and then the rats were randomly divided into sham-operation group,model group,donepezil group,low-dose GLA group and high-dose GLA group,and high GLA+HMGB1 group,with 15 rats in each group.The Morris water maze test was used to assess the learning and memory abilities of rats;HE staining was used to observe the pathological and morphological changes of hippocampal tissue;ELISA was used to measure the lev-els of tumor necrosis factor-α(TNF-α),interleukin-6(IL-6),and interleukin-1β(IL-1β)in hippocampal tissue;immu-nofluorescence assay was used to measure the expression of the microglia marker protein Iba-1 and the astrocyte marker protein GFAP;Western blotting was used to measure the expression of HMGB1-RAGE pathway-related proteins in hippo-campal tissue.Results Compared with the sham-operation group,the model group had significant increases in escape la-tency,the content of TNF-α/IL-6/IL-1β,the positive expression area of Iba-1 and GFAP proteins,and the expression lev-els of HMGB1,RAGE,TLR4,and p-NF-κB p65/NF-κB p65(P<0.05),as well as significant reductions in the time spent in the target quadrant and the number of platform crossings(P<0.05).Compared with the model group,the low-and high-dose GLA groups had significant reductions in escape latency,the content of TNF-α/IL-6/IL-1β,the positive ex-pression area of Iba-1 and GFAP proteins,and the expression levels of HMGB1,RAGE,TLR4,and p-NF-κB p65/NF-κB p65(P<0.05),as well as significant increases in the time spent in the target quadrant and the number of platform crossings(P<0.05),and there were no significant differences between the high-dose GLA group and the donepezil group(P>0.05).Further supplementation experiments using HMGB1 recombinant protein showed that the inhibitory effect of GLA on neuroinflammation was reversed,with a sig-nificant increase in the level of RAGE(P<0.05).Conclusion GLA can alleviate neuroinflammation in AD rats by inhibiting the HMGB1-RAGE signaling pathway.

Objective:To explore the clinical outcome and applicability of the comb flap technique and stepwise design concept in plastic aesthetic and reconstructive surgery.Methods:The clinical data of patients who underwent plastic aesthetic and reconstructive surgery with the comb flap technique in Shanghai Ninth People’s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2022 were retrospectively analyzed. The application of the comb flap technique follows the concept of stepwise design, that was, preoperative and intraoperative design and adjustment were carried out step by step and in sequence, and the design was combined with the surgical procedure. Its main operations included: an incision was designed along the edge of the target area, the tissue flap was widely separated at the base of the target area. The tissue flap was cut in sequence perpendicular to the cutting edge and temporarily sutured and fixed, the edge was cut and fixed. During the operation, the tension of the incision and the local appearance could be adjusted. The incisal edge was finely sutured, and the temporary suture was finally removed. The healing of surgical incision and complications were observed after the operation, and the facial recovery and surgical effect were followed up.Results:Six patients were enrolled, including 3 males and 3 females, aged from 2 to 58 years. One patient underwent upper eyelid tightening and lower eyelid blepharoplasty through subeyebrow incision. One patient underwent middle and lower face rhytidectomy. One patient underwent thick lip thinning and right facial liposuction. One patient underwent facial congenital melanocytic nevi resection. One patient underwent eyebrow congenital melanocytic nevus resection. One patient underwent facial flap repair. All patients had primary healing of incision, and no surgery-related complications occurred. All patients were followed up for 3 to 18 months, and all patients were satisfied with the surgical effect.Conclusion:The application of comb flap technique and stepwise design concept in plastic aesthetic and reconstructive surgery can delicately adjust the alignment of the incision margin, make the tension evenly distributed, and reduce the risk of scar formation and deformity after the operation. It has a wide range of clinical applications and good applicability.

Objective To analyze the quality of life and its influencing factors among patients with occupational coal workers' pneumoconiosis (hereinafter referred to as "coal workers' pneumoconiosis"). Methods A total of 404 coal workers' pneumoconiosis patients diagnosed in Fengjie County of Chongqing City were selected as the study subjects using the convenient sampling method, and their quality of life was investigated by the SF-36 scale. Results The total score of quality of life of the subjects was (63.1±12.1) points. Their scores in the eight dimensions of physical functioning, role-physical, bodily pain, general health subscales, vitality, social functioning, role-emotional, and mental health subscales were lower than that of norms for Chongqing City and the nation (all P<0.05). The results of multiple linear regression analysis showed that the total score of quality of life of the patients decreased with the increase of age and stage of pneumoconiosis (all P<0.01). The total score of quality of life of patients living in urban areas was higher than that of rural patients(P<0.01). The total score of quality of life of patients who had left their jobs was higher than that of retired patients (P<0.01). The total score of quality of life of smoking patients and those with complications was lower than that of non-smokers and those without complications (all P<0.01). Conclusion Age, place of residence, smoking, stage of pneumoconiosis, work status, and complications of pneumoconiosis were the main influencing factors of quality of life among coal workers' pneumoconiosis patients.

Infantile hemangioma is a benign tumor which develops shortly after birth. An early diagnosis and treatment should be performed for baby with facial hemangioma to avoid mental burden and family burden in the future. Therefore early prevention of the diseaseisvery important.

Objective: To explore and evaluate the approach of fat repositioning into premaxillary and prezygomatic spaces combined with intraoral fixation in transconjunctival lower blepharoplasty. Methods: 17 patients (2 males and 15 females) who underwent this approach from Aug, 2018 to Feb, 2019 were reviewed. Their average age was 36.88±8.80 years old (range, 24 to 55 years old). A 1.0-1.5 cm transverse transconjunctival incision was made. After blunt dissection of premaxillary and prezygomatic spaces, orbital fat were released and sutured with 1-2 absorbable sutures. Via the guidance of astraight needle through the a forementioned spaces, a small incision was made at the upper vestibular labial side. The orbital fat was pulled down according to the consensus between surgeon and patient and fixed upon the small intraoral incision. All incisions didn′t need to be sutured. Results: The mean follow up was 3.53±1.71 months (range, 1 to 6 months), transconjunctival and intraoral incisons healed well. Palpebral bags and tear trough deformity were obviously improved. Postoperatively, 2 patients felt a transient tractive feeling in the midface region 1 week after surgery, which spontaneously recovered within 1 to 2 weeks. One patient had red, swollen and painful skin beside the right nasal alar one month after the operation, and the symptoms disappeared after 3-day intravenous infusion of cefradine. No lower eyelid retraction, ectropion, hematoma and other complications were observed. Conclusions This novel approach can achieve periorbital rejuvenation and improve the contour of the lower eyelid and mid-face for patients of all the ages with eyelid bags, tear trough deformity, and midfacial depression, but without severe skin laxity.
