The use of buccal mucosa and a tongue flap in reconstruction of full-thickness defects of the lower lip is described. The patient's face received a heavy blow in a traffic accident. Necrosis caused by hematogenous disturbance occurred in more than half of the entire lower lip vermilion. The patient underwent a two-stage operation for reconstruction of the lower lip. First, vestibuloplasty was performed using a buccal mucosal flap. Subsequently, the vermilion was surgically reconstructed using a flap from the tip of the tongue. This operative method is less risky because of its favorable prognosis. An effective way to recover motor function of the lower lip is to practice a rehabilitation program against scar contraction. An extension movement with the fingers that requires two or three repetitions every day was selected. Rehabilitation was started 7 days after the tongue flap was divided. The patient had a favorable recovery after the operation and is now able to wear a denture and to eat without slobbering.

: Surgical treatment of extensive tumors of the lower lip generates important defects in its structure and functions. Over time, a multitude of reconstruction options for these defects have been imagined. Unfortunately, the majority involve the use of both local and regional flaps, which either lack labial structure or disorganize the oral commissures as nodal oral function points.

The emergence of multidrug-resistant bacteria presents a significant global health threat. Liposomal antibiotics have shown a potential to improve antibiotic delivery and efficacy. This study aimed to develop liposomes encapsulating tobramycin (TOB) and methylglyoxal (MGO) to enhance TOB activity while reducing bacterial adhesion and biofilm formation.

Objective: To establish a similarity measurement model for patients with dentofacial deformity based on 3D craniofacial features and to validate the similarity results with quantifying subjective expert scoring.
Methods: In the study, 52 cases of patients with skeletal Class Ⅲ malocclusions who underwent bimaxillary surgery and preoperative orthodontic treatment at Peking University School and Hospital of Stomatology from January 2020 to December 2022, including 26 males and 26 females, were selected and divided into 2 groups by sex. One patient in each group was randomly selected as a reference sample, and the others were set as test samples.
Soluble microneedle acupuncture patches containing melittin liposomes for the percutaneous treatment of rheumatoid arthritis.

Bee venom acupuncture (BVA) offers therapeutic potential for rheumatoid arthritis (RA) but faces challenges from pain and allergies linked to live bee stings. A key hurdle is melittin (Mel), bee venom's main anti-inflammatory component, which degrades rapidly when orally ingested, leading to decreased efficacy and increased toxicity. This study proposes a solution by encapsulating melittin in liposomes to enhance stability and lessen side effects, expanding its clinical applicability.
