Based on the theory of the five-body constituents from Huangdi Neijing (Yellow Emperor's Internal Classic), the approach and methods of acupuncture for facial aging are explored. Acupuncture for facial aging can be guided by the concept of the five-body constituents, targeting the facial "skin, flesh, vessels, tendons, and bones", and utilizing five different types of needles-facial needles, needle knives, filiform needles, retaining needles, and elongated needles and filiform needles-to maximize their respective advantages in treating facial aging. Facial needles are applied to the "skin" by selecting facial acupoints or local ashi points (at wrinkle or pigmentation sites). Needle knives are used for the "flesh" to perform longitudinal dredging and transverse dissection of the facial muscle layers. Filiform needles target the "vessels" with needling at Renying (ST9) to improve facial complexion. Retaining needles act on the "tendons" with needling from Taiyang (EX-HN5) to Xiaguan (ST7), and Jiache (ST6) to Daying (ST5), using clockwise twisting to generate a retaining needle sensation and lifting to achieve an overall facial lifting effect.

Mesangial cell proliferation is an early pathological indicator of diabetic nephropathy (DN). Growing evidence highlights the pivotal role of paired-related homeobox 1 (Prrx1), a key regulator of cellular proliferation and tissue differentiation, in various disease pathogenesis. Notably, Prrx1 is highly expressed in mesangial cells under DN conditions. Both in vitro and in vivo studies have demonstrated that Prrx1 overexpression promotes mesangial cell proliferation and contributes to renal fibrosis in db/m mice. Conversely, Prrx1 knockdown markedly suppresses hyperglycemia-induced mesangial cell proliferation and mitigates renal fibrosis in db/db mice. Mechanistically, Prrx1 directly interacts with the Yes-associated protein 1 (YAP) promoter, leading to the upregulation of YAP expression. This upregulation promotes mesangial cell proliferation and exacerbates renal fibrosis. These findings emphasize the crucial role of Prrx1 upregulation in high glucose-induced mesangial cell proliferation, ultimately leading to renal fibrosis in DN. Therefore, targeting Prrx1 to downregulate its expression presents a promising therapeutic strategy for treating renal fibrosis associated with DN.

Objective:To evaluate the effects and underlying mechanisms of metabolites derived from the kidney-reinforcing, blood circulation-activating, and collateral dredging decoction on the proliferation of multiple myeloma (MM) KM3 cells.Methods:MM KM3 cells in the logarithmic growth phase were treated with 3%, 6%, 9%, or 12% metabolites of kidney-reinforcing, blood circulation-activating, and collateral dredging decoction. Cell viability was assessed using the CCK-8 assay. Apoptosis and necrosis were evaluated using flow cytometry and TUNEL staining. Mitochondrial and cellular ultrastructural changes were examined using transmission electron microscopy. mRNA and protein expression levels of dynamin-related protein 1 (Drp1), mitochondrial fission protein 1 (Fis1), mitochondrial fission factor (MFF), PTEN-induced kinase 1 (Pink1), and E3 ubiquitin ligase (Parkin) were determined through quantitative real-time PCR and western blotting. High-performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS) combined with network pharmacology, was utilized for reverse verification of the pharmacodynamic mechanisms and therapeutic targets underlying the anti-MM activity of this decoction.Results:The metabolites of the kidney-reinforcing, blood circulation-activating, and collateral dredging decoction inhibited KM3 cell proliferation and induced apoptosis in a dose-dependent manner. Transmission electron microscopy revealed increased mitochondrial fission and autophagic structures, with effects intensifying at higher metabolite concentrations. mRNA and protein expression of Drp1, Fis1, MFF, Pink1, and Parkin were significantly upregulated in treatment groups compared to controls ( P<0.05), with the most pronounced effects observed in the 12% metabolite group ( P<0.01). HPLC-MS/MS identified 121 bioactive compounds in BHTF, which shared 474 overlapping targets with MM. Enrichment analysis suggested that BHTF exerts antitumor effects primarily through apigenin, palmatine, and other key components by modulating TNF, NF-κB, and mitophagy pathways. Conclusion:The kidney-reinforcing and blood circulation-activating and collateral dredging decoction suppresses the proliferation of MM KM3 cells, potentially through mechanisms involving the regulation of mitochondrial dynamics and induction of autophagy.

Objective:To evaluate the clinical outcomes of endoscopic-assisted polyether ether ketone (PEEK) patient-specific implant (PSI) revision for over-resected mandibles caused by the mandibular angle osteotomy.Methods:A retrospective analysis was conducted on 24 patients [8 males, 16 females, aged 19-57 (32.5±9.5) years] with 39 over-resected mandibles that underwent PEEK-PSI mandibular angle revision surgery at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from January 2019 to December 2023. Preoperative cone-beam computed tomography (CBCT) data were used to design and fabricate customized PEEK PSIs based on individual anatomical requirements. An intraoral incision approach with endoscopic assistance was employed to meticulously dissect soft tissue attachment around the angle region, followed by the implantation of a customized PEEK PSI. Postoperative CBCT scans were performed for 3D reconstruction, with root mean square error (RMSE) and maximum deviation (MaxD) as accuracy metrics. Patients′ satisfaction was assessed preoperatively and ≥6 months postoperatively using the face questionnaire (FACE-Q) scores, which included overall facial appearance, lower face and jawline, appearance distress, psychological health and social function.Results:All 24 patients achieved satisfactory recovery with primary healing of intraoral incisions. No complications such as infection, nerve injury, or implant rejection occurred during follow-up period. Patients′ facial appearance and jaw line contouring were significantly improved. Fine anatomical fitting between PEEK-PSI and defect areas was observed: RMSE ranged from 0.117 to 0.315 mm, and MaxD was (5.485±1.300) mm. FACE-Q scores demonstrated significant improvements after surgery in overall facial appearance [(49.8±5.4) vs (65.0±5.3) scores], lower face and jawline [(42.5±5.3) vs (56.1±4.6) scores], appearance distress [(60.0±6.9) vs (70.6±6.5) scores], psychological health [(62.0±5.0) vs (70.8±5.3) scores], and social function [(60.3±4.3) vs (69.3±5.8) scores] (all P<0.001). Conclusion:Endoscopic-assisted PEEK-PSI revision for over-resected mandibles following mandibular angle osteotomy exhibits high surgical precision and safety, effectively restoring mandibular contour and significantly enhancing patients′ satisfaction.

Objective:To investigate the clinical outcomes of precapsular pocket repositioning for correcting implant malposition following augmentation mammoplasty.Methods:A retrospective analysis was conducted on 29 female patients aged 25-37 (28.8±3.4) years who underwent precapsular pocket repositioning at the Affiliated Friendship Plastic Surgery Hospital of Nanjing Medical University from December 2015 to August 2024. The surgical technique involved preserving the original capsule, creating a new implant pocket anterior to the capsule, and closing the original capsular space. Postoperative complications were recorded, and breast satisfaction was evaluated preoperatively and at 6 months postoperatively using the BREAST-questionnaire (BREAST-Q).Results:All 29 patients successfully underwent precapsular pocket repositioning with primary wound healing. During the follow-up period, all patients were satisfied with the correction of implant malposition. The mean BREAST-Q score improved significantly from (43.56±3.17) scores preoperatively to (72.56±13.49) scores at 6 months postoperatively ( P<0.001). No hematoma, implant rupture, recurrent malposition, capsular contracture, or surgical site infection occurred in any patient. Conclusion:Precapsular pocket repositioning provides favorable clinical outcomes for patients with implant malposition after augmentation mammoplasty, and there are no severe complications .
