This paper explores the research progress of acupuncture for the prevention and treatment of Alzheimer's disease (AD) based on the "kidney-governor vessel-brain" axis. According to the fundamental pathogenesis of AD in traditional Chinese medicine (TCM), which attributes to kidney deficiency, marrow depletion, and impaired mental faculties, as well as the governor vessel's connection between the kidney and brain, the concept of the "kidney-governor vessel-brain" axis is proposed. The theoretical basis of the "kidney-governor vessel-brain" axis is analyzed based on the meridian pathway and physiological functions of the governor vessel, as well as the interdependent and mutually reinforcing relationships among the kidney, governor vessel, and brain. The relationship between AD and the "kidney-governor vessel-brain" axis is elucidated from both traditional medical theories and modern biological perspectives. Integrating clinical and mechanistic research on AD prevention and treatment based on this axis, it is suggested that the "kidney-governor vessel-brain" axis provides valuable insights and references for future research on AD prevention and treatment.

Panvascular disease is a complex systemic disorder. Research by our team has established "kidney deficiency-vascular impairment" as its core pathogenesis. Consequently, we developed a three-tiered progressive prevention and treatment strategy: early prevention phase: focuses on tonifying the kidney and reducing turbidity; mid-term control phase: focuses on tonifying the kidney and stabilizing plaque; late recovery phase: focuses on tonifying the kidney and unblocking collaterals. This targeted therapeutic protocol effectively alleviates clinical symptoms, improves biochemical markers, enhances treatment efficacy, and achieves comprehensive management throughout the disease course. This article systematically elaborates on the concept of "kidney deficiency-vascular impairment" in panvascular disease, summarizes the mechanisms of kidney-tonifying Chinese herbal medicines, aiming to provide a beneficial reference for the whole-course management of panvascular diseases.

OBJECTIVE: Angiogenesis is a critical target for hepatocellular carcinoma (HCC) treatment. The previous studies indicated that Jiedu Fang (JDF) could inhibit hypoxia-induced angiogenesis through interleukin-8 (IL-8). Therefore, the present study further explores the mechanisms behind JDF's inhibition of HCC angiogenesis. METHODS: Angiogenesis was assessed with the capillary-like tube formation assay in vitro and the matrigel plug angiogenesis assay in vivo. A liver cancer-related gene set and genes associated with angiogenesis and the hypoxic microenvironment were analyzed using a bioinformatics platform. Real-time reverse transcription-polymerase chain reaction and Western blotting assays were used to assess the targeted mRNA and protein levels, respectively. The Transwell assay was used to assess the migration and invasion potential of EA.hy 926 cells. The orthotopic tumor xenograft model was established, and immunohistochemistry and immunofluorescence assays were used to detect cluster of differentiation 31 and angiopoietin 2 expression, while an enzyme-linked immunosorbent assay was used to detect vascular endothelial growth factor and IL-8 protein levels. RESULTS: In vitro and in vivo assays showed that IL-8 promoted angiogenesis, and JDF could antagonize this effect. Bioinformatics analysis indicated that aurora kinase A (Aurora A) was an important candidate, which can promote IL-8 expression through activation of signal transducer and activator of transcription 3 (STAT3). The overexpression of Aurora A increased IL-8 secretion and promoted HCC migration, invasion, and angiogenesis, which was partly inhibited by JDF. Such effects were validated by in vivo assays. Further validation using the STAT3 inhibitor S3I-201 demonstrated that STAT3 was regulated by Aurora A. CONCLUSION JDF exhibits efficacy in reducing hypoxia-induced angiogenesis in HCC through a mechanism involving the Aurora A/STAT3/IL-8 signaling pathway. Therefore, JDF holds promise as a potential therapeutic approach for targeting HCC angiogenesis. Please cite this article as: Zhong MF, Luo YJ, Guo YY, Xiang S, Lin WF.

Hepatic ischemia/reperfusion injury (IRI) remains a critical complication contributing to graft dysfunction following liver surgery. As part of an ongoing search for hepatoprotective natural products, five previously unreported homoadamantane-type polycyclic polyprenylated acylphloroglucinols (PPAPs), named hyperhomanoons A-E (1-5), and one known analog, hypersampsone O (6), were isolated from Hypericum patulum. Among these, compound 6 demonstrated potent protective effects against CoCl₂-induced hypoxic injury in hepatocytes. Furthermore, in a murine model of hepatic IRI induced by vascular occlusion, pretreatment with 6 markedly alleviated liver damage and reduced hepatocyte apoptosis. This study is the first to identify PPAPs as promising scaffolds for the development of therapeutic agents targeting hepatic IRI, underscoring their potential as lead compounds in drug discovery efforts for ischemic liver diseases.

OBJECTIVES: Color doppler flow imaging (CDFI) and cone-beam computed tomography (CBCT) were utilized to evaluate changes in mucosal vascular parameters and the osteogenic effects following guided bone regeneration (GBR) in the maxillary anterior region using trapezoidal or modified triangular flaps. METHODS: Patients undergoing single maxillary anterior dental implant surgery with GBR were randomly allocated into two groups: a trapezoidal flap group and a modified triangular flap group. After GBR surgery, the mucosal vascular parameters at the surgical site were assessed at various time intervals (preoperative, 2 h, 1 and 3 days, and 1, 2, and 4 weeks postoperative) using CDFI. In addition, the effects of bone augmentation were evaluated through the analysis of CBCT images obtained preoperatively, 2 h, and 6 months postoperative. RESULTS: The buccal mucosa in the edentulous area had a lower blood flow rate than the corresponding tooth in the same jaw, and the difference was statistically significant (P<0.001). The mucosal blood flow rate in the surgical area increased compared with that in the preoperative period. The peak flow rate was recorded at 2 weeks postoperatively and then decreased to levels comparable to those of the reference tooth. A statistically significant difference was observed between the two groups (P<0.05). The buccal alveolar ridge width of the implant platform was reduced by (1.3±0.9) mm in the trapezoidal flap group and (0.9±0.7) mm in the modified triangular flap group, respectively, at 6 months postoperatively, compared with 2 h postoperative. The buccal alveolar ridge width of the 5 mm from the implant platform was reduced by (0.9±0.6) mm and (0.3±0.6) mm, respectively. The buccal alveolar ridge width of the 10 mm from the implant platform was reduced by (0.6±0.8) mm and (0.2±0.6) mm, respectively. The height of the alveolar ridge was reduced by (1.9±1.4 ) mm and (1.4±1.3) mm. The change in graft volume was (136±78 ) mm³ and (114±85) mm³. However, the differences between the two groups were not statistically significant (P>0.05). CONCLUSIONS When a tooth is missing, blood flow to the buccal mucosa on the side of the missing tooth is reduced. The modified triangular flap group demonstrated superior microcirculation of blood flow in the operative area after GBR of the maxillary anterior teeth. Trapezoidal and modified triangular flaps achieved the anticipated bone augmentation during bone augmentation surgery in the maxillary anterior region, with no considerable effect on the changes in alveolar bone size parameters.

OBJECTIVE: To review the latest research advancements in surgical techniques for the treatment of limb lymphedema. METHODS: The relevant literature at home and abroad in recent years was extensively reviewed, and the research on the treatment of limb lymphedema by surgical techniques were summarized and analyzed. RESULTS: Lymphovenous anastomosis has demonstrated good effectiveness for early to mid-stage limb lymphedema, however its long-term effectiveness and applicability for late-stage limb lymphedema still require further validation. Autologous lymphatic/venous grafting has shown clinical feasibility in the treatment of secondary limb lymphedema. Research on tissue-engineered lymphatic scaffolds remains insufficient, primarily due to the complexity of lymphatic anatomical structures and the technical challenges involved. Nevertheless, its potential application is promising. Vascularized lymph node flap transplantation has shown significant effectiveness in treating limb lymphedema, particularly yielding good outcomes in upper limb cases. However, it can not guarantee a complete cure for the condition. Charles' operation is the most effective treatment option for patients with late-stage limb lymphedema, but its extensive incision and severe postoperative complications limit its application. Liposuction has the advantages such as minimal invasiveness, high safety, and repeatability. It is suitable for patients with late-stage limb lymphedema who have failed conservative treatment or developed adiposity. However, its effectiveness is limited in patients with significant limb fibrosis. CONCLUSION Current treatments for limb lymphedema require further improvement, and there is considerable debate regarding treatment strategies for different stages of the condition. Future high-quality, multi-system combined treatment approaches are anticipated to guide clinical practice.

OBJECTIVE: To investigate the efficacy of minimally invasive osteotomy with preservation of blood supply to the transversely transported bone segment in the treatment of chronic ischemic lower limb diseases using tibial transverse bone transport. METHODS: A retrospective analysis was conducted on the clinical data of 12 patients with chronic ischemic lower limb diseases who met the selection criteria and were treated between June 2016 and December 2023. The cohort included 7 males and 5 females, aged 26-87 years (mean, 61.2 years). Among them, 7 patients had diabetic foot (DF), including 2 cases complicated by arteriosclerosis obliterans (ASO), with a DF duration ranging from 1.7 to 23.0 months (mean, 9.6 months) and ulcer sizes ranging from 3.2 cm×2.4 cm to 10.0 cm×6.6 cm. Three patients had ASO with a disease duration of 1.7-23.0 months (mean, 10.4 months) and ulcer or post-amputation wound sizes ranging from 2.2 cm×2.1 cm to 12.0 cm×7.7 cm. Additionally, 2 patients with thromboangiitis obliterans (TAO) had a disease duration of 7 and 12 months, respectively. Preoperatively, the mean foot skin temperature was (27.63±0.34)℃, and the visual analogue scale (VAS) score was 8.5±0.7. All patients underwent tibial transverse bone transport using minimally invasive osteotomy while preserving the blood supply to the transported bone segment. Postoperative complications and foot ulcer healing were observed. The effectiveness of tibial transverse bone transport was evaluated by comparing preoperative and postoperative foot skin temperature, VAS scores, as well as through CT angiography (CTA). RESULTS: One DF patient with ASO was lost to follow-up, while the remaining 11 patients were followed up 10-29 months (mean, 20.5 months). One DF patient had a displaced fracture at the site of tibial transport due to trauma, which healed after plaster immobilization; 1 DF patient had a small amount of pigmentation in the skin of the donor site, but the blood circulation was good; no complication such as pin tract infection, skin necrosis, or osteomyelitis occurred in the donor site of all patients. At 2-3 weeks postoperatively, the foot skin temperature was (34.21±0.65)℃, and the VAS score was 0.3±0.1, both significantly improved compared to preoperative ones ( t=-31.578, P<0.001; t=49.000, P<0.001). Two TAO patients experienced recurrent, persistent, intolerable pain at 7-10 days postoperatively, with no reduction in ulcer size or necrotic areas; 1 underwent toe amputation, and the other required a mid-leg amputation. The remaining patients achieved complete ulcer healing, with healing time ranging from 5.1 to 9.2 weeks (mean, 6.8 weeks). CTA showed no new vascular occlusions or embolisms. X-ray films at 4 months postoperatively demonstrated proper repositioning and good healing of the transported tibial bone segment. CONCLUSION The application of minimally invasive osteotomy with preserved blood supply to the transversely transported bone segment in tibial transverse bone transport for the treatment of chronic ischemic lower limb diseases effectively minimizes extensive soft tissue dissection, reduces surgical soft tissue damage, and better maintains local blood supply. This approach lowers the risk of postoperative infection and skin necrosis while accelerating postoperative recovery.

OBJECTIVE: To investigate the accuracy of color Doppler ultrasound (CDU) and CT angiography (CTA) in the preoperative evaluation of perforator vessels in free posterior interosseous artery perforator (PIAP) flaps. METHODS: Between January 2020 and December 2023, 19 patients with hand skin and soft tissue defects caused by trauma were admitted. There were 11 males and 8 females, with a median age of 45 years (range, 26-54 years). The interval between injury and admission was 5-11 days (mean, 7.2 days). The skin and soft tissue defects were located on the dorsum of the hand in 8 cases and on the fingers in 11 cases. The size of defect ranged from 4.0 cm×2.5 cm to 7.5 cm×3.5 cm. After locating the perforator vessels through CDU and CTA before operation, the free PIAP flaps were designed to repair hand defects, with the size of 4.5 cm×3.0 cm-7.5 cm×4.0 cm. The defects of donor sites were directly sutured. The number and diameter of perforator vessels in the posterior interosseous artery detected by CDU and CTA were compared. The differences in localization of perforator vessels using CDU and CTA and their clinical effects were also compared to calculate the accuracy and recognition rate. During follow-up, the survival of the skin flap was observed, and the Vancouver scar scale (VSS) score was used to evaluate the healing of the donor site, while the visual analogue scale (VAS) score was used to evaluate the patient's satisfaction with the appearance of the skin flap. RESULTS: The number and the diameter of PIAP vessels was 5.8±1.2 and (0.62±0.08) mm assessed by CDU and 5.2±1.0 and (0.60±0.07) mm by CTA, showing no significant difference between the two methods ( P>0.05). The number, course, and distribution of perforator vessels of the PIAP vessels observed during operation were basically consistent with those detected by preoperative CDU and CTA. Compared with intraoperative observation results, the recognition rates of dominant perforating vessels by CDU and CTA were 95.0% (18/19) and 89.5% (17/19), respectively, and the accuracy rates were 100% (19/19) and 84.2% (16/19), with no significant difference between the two methods ( P>0.05). All flaps survived after operation, and all wounds and incisions at donor sites healed by first intention. All patients were followed up 6-13 months (mean, 8.2 months). At last follow-up, the skin flaps had elasticity and soft texture，with the patient satisfaction VAS score of 9.2±0.8. The donor sites had no obvious scar hyperplasia with the VSS score of 11.7±0.9. CONCLUSION CDU and CTA accurately identify the dominant perforator vessels and provide reliable information for vessel localization, facilitating precise flap harvesting and minimizing donor site injury. However, CDU offers superior visualization of distal end of perforator vessels in the forearm compared to CTA.

OBJECTIVE: To investigate of effectiveness of free fascia lata flap assisted by indocyanine green angiography (ICGA) in treatment of Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures. METHODS: A clinical data of 14 patients with Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures between March 2020 and June 2024 was retrospectively analyzed. All Achilles tendon defects were repaired with the free fascia lata assisted by ICGA during operation. There were 12 males and 2 females with an average age of 45.4 years (range, 26-71 years). The causes of Achilles tendon rupture included sports injury in 10 cases, Achilles tendon-related tendinopathy in 3 cases, and glass laceration injury in 1 case. The time from Achilles tendon rupture to operation was 4-40 weeks (median, 4.5 weeks). Preoperative MRI examination showed that the defect length of the Achilles tendon was 2-5 cm (mean, 3.2 cm). The operation time and intraoperative blood loss were recorded. The color Doppler ultrasound (CDU) and MRI were taken to observe the foot blood vessels and the tendon healing. The visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, Achilles Tendon rupture score (ATRS), and range of motion of the ankle joint were used to estimate the pain and function of ankle joint. RESULTS: All operations of the 14 patients were successfully completed. The operation time ranged from 3.00 to 4.50 hours (mean, 3.60 hours). The intraoperative blood loss ranged from 10 to 50 mL (mean, 36.4 mL). After operation, 1 patient had exudation at the recipient site, which healed after dressing change; the other incisions healed by first intention. All incisions at the donor sites healed by first intention. All patients were followed up 6-36 months (mean, 11.4 months). The CDU of the foot at 1 month after operation showed that the blood flow signal of the perforating vessels of the fascia lata flap was clear. The ankle MRI at 2 months after operation showed the good continuity of the Achilles tendon. No complication such as the Achilles tendon re-rupture, ankle stiffness, or scar contracture occurred during follow-up. Compared with preoperative score, the AOFAS score, ATRS score, and plantar flexion range of motion significantly increased at 1, 3, and 6 months after operation ( P<0.05), while the VAS score and dorsiflexion range of motion significantly decreased ( P<0.05). The AOFAS score, ATRS score, and VAS score at 3 and 6 months further improved when compared with those at 1 month ( P<0.05); however, there was no significant difference in the range of motion of the ankle joint ( P>0.05). There was no significant difference in above indicators between 3 and 6 months after operation ( P>0.05). CONCLUSION The treatment of Myerson type Ⅱ and Ⅲ chronic Achilles tendon ruptures with free fascia lata flaps under the guidance of ICGA has the advantages of precise design, fast healing, and a wide range of adaptability.
