Annexin A3（ANXA3）is a member of the membrane associated protein family. It has two subtypes of 36 kDa and 33 kDa. Its gene is located on the fourth chromosome of human. ANXA3, widely expressed in human bone marrow, lung, placenta, prostate and thyroid, is closely related to several biological processes such as exoplasmosis, vascular production, fat cell maturity, and white blood cell migration. Studies have found that ANXA3 is abnormally expressed in various diseases including cancer, cardiovascular disease and inflammation. It can regulate multiple signaling pathways such as JNK, NF-κB, PI3K/AKT, and may become a potential drug target for treatment of related diseases. The structure, functions, the link with diseases and related mechanisms of ANXA3 were summarized in this paper, which could provide reference for ANXA3 related research.

Objective To investigate the effect of glycerin enema in preoperative intestinal preparation for anorectal benign diseases.Methods A total of 74 patients with benign anorectal diseases admitted to the anorectal department of our hospital from September 2023 to December 2023 were selected as the study ob-jects.According to different preoperative intestinal preparation methods,they were divided into glycerol group(n=30)and compound polyethylene glycol electrolyte powder(PEG-EP)group(n=44).The glycerol group was treated with glycerol enema to clean the intestine,and the PEG-EP group was treated with PEG-EP ene-ma before operation.Adverse reactions,defecation frequency,intestinal cleanliness,intestinal preparation tol-erance,first postoperative defecation time and bowel quality were observed and compared between the two groups.Results Propensity score was used for 1∶1 matching,and 25 patients were included in the two groups after PSM.The main adverse reactions were abdominal pain in the glycerol group and nausea,abdomi-nal distension and diarrhea in the PEG-EP group.There was no significant difference in the incidence of ad-verse reactions between the two groups(P＞0.05).Compared with the PEG-EP group,the number of bowel movements after bowel preparation in the glycerol group was less,the intestinal preparation tolerance rate was higher,and the time of first postoperative bowel movement was earlier,with statistical significance(P＜0.05).Conclusion Glycerin enema has more advantages than oral PEG-EP in preoperative intestinal prepara-tion for anorectal benign diseases.

Objective:To investigate the clinical efficacy of anterolateral thigh free fat flap (hereinafter referred to as fat flap) transplantation with vascular anastomosis for reconstructing facial depressed scars.Methods:This study was a retrospective observational study. Twelve patients (5 males and 7 females, aged 15-67 years) with facial depressed scars who met the inclusion criteria were treated at the First Affiliated Hospital of Air Force Medical University from June 2017 to September 2023. Before surgery, the patient and observer scar assessment scale (POSAS) was used to evaluate the facial scar condition of the patients. Scar depression area was measured ranging from 5 cm×4 cm to 14 cm×7 cm, with a depth from 6 to 12 mm. All cases were reconstructed with fat flaps. The harvested fat flaps ranged 6 cm×5 cm to 15 cm×8 cm in size, with vascular pedicle lengths ranging from 4 to 7 cm. Intraoperatively, the number of perforator vessels observed was as follows: 1 perforator in 2 cases, 2 perforators in 7 cases, and 3 perforators in 3 cases. Fat flaps were transplanted to the recipient sites, with the main trunks of its perforator vessels and accompanying veins anastomosed to the recipient arteries and veins. Donor site wounds were closed primarily. Postoperatively, the survival of fat flap, vascular crisis, and the healing of donor site incision were observed. During follow-up, the facial contour was observed, the long-term reintervention at recipient sites was recorded, and the scars formed at both donor and recipient incisions were observed. The function of donor limb was assessed. At the last follow-up, the scar condition at recipient site was evaluated using the two subscales of POSAS (the observer scale and the patient self-rating scale), respectively.Results:One patient developed a mild hematoma due to bleeding within 24 hours after surgery. After timely removal of the hematoma and enhanced drainage, the fat flap survived. The fat flaps of the other patients survived completely with no vascular crisis occurred. The donor site incision of 1 patient developed infection 7 days after surgery and healed after timely dressing changes, while the donor site incisions of the remaining patients all healed smoothly. During the follow-up of 6-26 months, significant improvement in facial symmetry was observed in all patients, with natural fullness achieved. Autologous microlipofilling was performed in 2 patients at 6 months and 10 months postoperatively, respectively. Local liposuction contouring was conducted in 1 patient at 12 months postoperatively. The scars at the donor and recipient sites were mild. No functional impairment at donor sites was recorded, and the motor and sensory functions of the affected limbs were normal. At the last follow-up, the observer scale assessment showed that the scores for vascularity, thickness, roughness, pliability, pigmentation, and overall assessment of the scars in the recipient areas were 2.1±0.5, 1.9±0.7, 3.0±0.7, 2.1±1.2, 3.8±1.1, and 2.8±0.5, respectively, which were significantly lower than 4.2±0.9, 5.1±1.0, 4.2±1.5, 4.6±1.4, 4.8±1.2, and 5.2±1.0 before surgery (with t values of 7.24, 11.70, 4.31, 9.57, 4.17, and 9.30, respectively, P<0.05). The patient self-rating scale assessment showed that the scores for pain, pruritus, color, stiffness, irregularity, thickness, and overall satisfaction of the scars in the recipient areas were 1.3±0.5, 1.3±0.4, 1.9±1.0, 2.3±1.1, 1.8±0.8, 1.9±0.8, and 1.9±0.7, respectively, which were significantly lower than 2.9±1.0, 2.6±0.9, 4.2±1.5, 5.3±2.0, 4.0±1.2, 4.6±1.3, and 4.8±1.4 before surgery (with t values of 6.09, 5.20, 8.07, 9.17, 8.00, 8.60, and 8.81, respectively, P<0.05). Conclusions:Transplantation of the fat flaps with vascular anastomosis can safely and effectively reconstruct facial depressed scars, and significantly improve the aesthetic contour and scar-related symptoms. This technique yields stable long-term outcomes with high patient satisfaction, demonstrating high value of clinical application.
