Senile trichiasis is primarily manifested by eyelid laxity, decreased horizontal elasticity and tension of the eyelids, leading to friction between the eyelashes and the cornea, which subsequently causes corneal damage and vision decline. Surgical intervention remains the most effective therapeutic approach for senile trichiasis. This article elaborates on the epidemiological characteristics, pathological mechanisms, and clinical manifestations of senile trichiasis and systematically reviews the surgical treatment method for upper and lower eyelid trichiasis, including traditional surgical techniques and emerging minimally invasive procedures combined with personalized therapies. Through a literature review, the effectiveness and recurrence rates of surgical treatment are summarized, emphasizing the importance of preoperative assessment and individualized treatment. Additionally, strategies and recommendations for preventing senile trichiasis are proposed.

Objective:To investigate the effects of the histone deacetylase(HDAC)inhibitor panobinostat on melanoma growth,tumor immunity,and the underlying mechanisms.Methods:B16F0 melanoma cells were cultured and treated with different concentrations of panobinostat.The effect of panobinostat on HDAC expression in B16F0 cells was detected by WB.The effects of panobinostat on the proliferation,migration,invasion,apoptosis and cell cycle of B16F0 cells were detected by CCK-8 assay,wound-healing assay,Transwell assay and flow cytometry,respectively.The effect of panobinostat on gene expression in B16F0 cells was detected using transcriptome analysis and verified by qPCR.Flow cytometry was used to detect the effect of panobinostat on the expression of MHCⅠ/Ⅱ in B16F0 cells.B16F0 cells and bone marrow-derived dendritic cells(BMDC)were co-cultured to assess the effects of panobinostat on the expression of CD11c,CD80 and CD86 in BMDC cells.A xenograft mouse model was used to evaluate the effects of panobinostat on tumor growth and host immune function.Results:panobinostat promoted the acetylation of H3 and α-tubulin proteins in B16F0 cells(P<0.01 or P<0.001 or P<0.000 1),inhibited cell proliferation,migration,and invasion,promoted apoptosis,and induced G1-phase cell cycle arrest(P<0.05 or P<0.001 or P<0.000 1).Additionally,panobinostat enhanced surface expression of MHC Ⅰ/Ⅱ on B16F0 cells and promoted BMDC maturation(all P<0.01).Transcriptomic analysis showed that panobinostat upregulated the expression of E-cadherin and antigen presentation related genes in B16F0 cells,and inhibited the expression of N-cadherin,vimentin,c-Myc and CDK1,which was confirmed by qPCR.In vivo,panobinostat suppressed xenograft tumor growth and enhanced immune function in tumor-bearing nude mice(P<0.05,P<0.000 1).Conclusion:panobinostat can inhibit the malignant biological behavior of B16F0 cells,promote apoptosis,regulate tumor immunity,and enhance immune function of tumor-bearing nude mice.

Objective:To investigate the effect of laboratory indicators on hair loss in patients with female pattern hair loss (FPHL).Methods:Patients with FPHL who visited the Outpatient Clinic of the Department of Medical Aesthetics in Hangzhou First People’s Hospital from November 2022 to November 2023 were selected as the study group, and healthy women who matched the age of the study group in the physical examination center during the same period were selected as the control group. The general information of the patient was recorded, and was also tested by trichoscopy to rule out other patterns of alopecia. Representative indicators including testosterone, dehydroepiandrosterone sulfate(DHEA-S), thyroid-stimulating hormone, 25-hydroxyvitamin D, and serum ferritin were selected from laboratory tests for further analysis. Otherwise, the proportion of deficiency in vitamin D(<20 ng/ml) was calculated based on 25-hydroxyvitamin D levels (number of deficiency cases/total number of cases in each group×100%). Count data were presented as samples (percentages), and chi-square test was used for comparison between groups. Normally distributed continuous data were presented with Mean±SD, independent samples t-test was used for comparison between groups, M( Q1, Q3) was used for non-normally distributed continuous data, and Wilcoxon rank-sum test was used for comparison between groups. Multivariate logistic regression was used to analyze the influencing factors of FPHL. P<0.05 was statistically significant. Results:A total of 37 patients were selected in both groups. The mean age was (28.8±1.3) years in the study group and (29.6±0.9) years in the control group ( t=0.49, P=0.625). The body mass index was (22.8±0.4) kg/m 2 in the study group, and (23.5±0.3) kg/m 2 in the control group ( t=1.26, P=0.211). The testosterone level was 0.58 (0.49, 0.79) nmol/L in the study group, and 0.54 (0.50, 0.78) nmol/L in the control group( Z=1.42, P=0.157). The level of DHEA-S was 6.21 (5.18, 9.60) μmol/L in the study group, and 6.20 (5.20, 9.34) μmol/L in the control group ( Z=2.75, P=0.006). The level of thyroid-stimulating hormone was 2.56 (1.55, 3.66) mU/L in the study group and 1.49 (1.05, 2.65) mU/L in the control group ( Z=2.51, P=0.012). The level of 25-hydroxyvitamin D was 15.44 (11.80, 21.20) ng/ml in the study group, and the level of 25-hydroxyvitamin D was 20.32 (12.07, 21.20) ng/ml in the control group ( Z=2.30, P=0.021), and the proportion of 25-hydroxyvitamin D deficiency in the study group was 64.9% (24/37), which was higher than that in the control group [40.5% (15/37)] ( χ2=4.39, P=0.036). The serum ferritin level was 64.44 (39.47, 133.45) μg/L in the study group and 67.75 (52.63, 143.83) μg/L in the control group ( Z=0.70, P=0.484). The results of multivariate logistic regression analysis showed that the risk of FPHL was increased by the high level of DHEA-S and thyroid-stimulating hormone, and the low level of 25-hydroxyvitamin D (all P<0.05). Conclusion:Abnormal level of DHEA-S, thyroid-stimulating hormone, and 25-hydroxyvitamin D may be risk factors for FPHL.

Objective:To study the effect of bridge orbicularis oculi muscle flap blepharoptosis in the treatment of post-burn scar contracture ectropion.Methods:The clinical data of patients wih post-burn cicatricial ectropion treated with bridge orbicularis oculi muscle flap from April 2006 to September 2020 of Department of Plastic Surgery, Affiliated Hangzhou First People’s Hospital, School of Medicine, Westlake University were analyzed retrospectively. For patients with severe eyelid scar contracture caused by head and face burns, after releasing the scar and resetting the eyelid margin, orbicularis oculi muscle flaps were made at the base of the upper and lower eyelid release incision, crossed the muscle flap over the eyelid adhesion point of the eye fissure, by performed bridge cross transfer, and fixed to the orbicularis oculi muscle at the base of the release incision to form eyelid adhesion. H-shaped full-thickness skin graft or medium-thickness skin graft was performed on the defect wound during the operation. Tie-over dressing fixation in the skin graft area. One year after the operation, it was confirmed that the skin graft was stable and there was no recurrence of ectropion, and then cut the adhesion. Follow-up for more than one year after the operation, foreign body sensation, conjunctival sac pusc, skin graft survival, success rate of eyelid adhesion, anti-stretching effect of muscle flap, skin retraction rate and complications were observed. The distances between eyelid margins preoperative and after incision of eyelid adhesion were measured. SPSS 25.0 software was used for data statistics, measurement data was represented by M ( Q1, Q3), and counting data was represented by cases. Results:Fourteen patients (23 eyes) were included in this study, including 11 males and 3 females, aged 41.5 (32.5, 47.0) years, and the time from burn to this treatment was 13.5 (10, 24) months. 5 cases (7 eyes) were not treated with skin grafting or blepharoptosis after burn, and 9 cases (16 eyes) were treated with blepharoptosis and/or skin transplantation. The area of skin graft during operation was 37 mm ×18 mm to 52 mm ×39 mm. Before operation, the distance between the upper and lower eyelid margins was 14 (12, 14) mm when eyes were open, and 6 (5, 9) mm when eyes were closed. After eyelid adhesion surgery, the patient had no foreign body sensation and infection, and all the skin grafts survived. The success rate of blepharoptosis was 100%, and there was no accidental rupture or elongation. The eyelid adhesions contracted synchronously when the patients closed their eyes, and the muscle flap had good anti-stretching effect. The duration of blepharoptosis was 13(12, 24) months, during which no complications or adverse reactions occurred. The average skin graft retraction rate was 9% (5%, 10%) in half a year. After incision of the orbicularis oculi muscle flap, the distance between the upper and lower eyelid margins was 9 (8, 9) mm when the eyes were open, and 0 (0, 0) mm when the eyes were closed.Conclusion:Bridge orbicularis oculi muscle flap tarsorrhaphy can provide long-term tarsorrhaphy, effectively reduce skin contracture after eyelid skin grafting, and has a stable therapeutic effect on postburn ectropion.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.
