Ligusticum sinense cv.Fuxiong derived from"Xiongqiong",and in the Song Dynasty's Tai Ping Hui Min He Ji Ju Fang,it was already distinguished from Chuanxiong Rhizoma in usage.Doctors in the Ming Dynasty further clarified the differences in efficacy between the two.However,with the widespread circulation of Chuanxiong Rhizoma,Ligusticum sinense cv.Fuxiong gradually became marginalized,serving as a substitute,and is now only cultivated and used in small quantities within Jiangxi Province.This article reviewed the prescriptions and the ancient Chinese medical books that have records of Ligusticum sinense cv.Fuxiong,analyzed its specific applications alongside Chuanxiong Rhizoma in prescriptions and case studies to elucidate their differences in efficacy:Ligusticum sinense cv.Fuxiong is pungent and has strong dispersing power and is good at unblocking meridians and promoting qi circulation,which is suitable for excessive syndromes;Chuanxiong Rhizoma is good at promoting blood circulation and relieving pain,and is good at regulating and nourishing,which is suitable for patients with deficiency syndromes,aiming to provide insights and recommendations for the further development and rational clinical medication of Ligusticum sinense cv.Fuxiong.

(+)-Borneol, the main component of "Natural Borneol" in the Chinese Pharmacopoeia, is a high-end spice and precious medicine. Plant extraction cannot meet the increasing demand for (+)-borneol, while microbial biosynthesis offers a sustainable supply route. However, its production was extremely low compared with other monoterpenes, even with extensively optimizing the mevalonate pathway. We found that the key challenge is the complex and unusual dephosphorylation reaction of bornyl diphosphate (BPP), which suffers the side-reaction and the competition from the cellular dephosphorylation process, especially lipid metabolism, thus limiting (+)-borneol synthesis. Here, we systematically optimized the dephosphorylation process by identifying, characterizing phosphatases, and balancing cellular dephosphorylation metabolism. For the first time, we identified two endogenous phosphatases and seven heterologous phosphatases, which significantly increased (+)-borneol production by up to 152%. By engineering BPP dephosphorylation and optimizing the MVA pathway, the production of (+)-borneol was increased by 33.8-fold, which enabled the production of 753 mg/L under fed-batch fermentation in shake flasks, so far the highest reported in the literature. This study showed that rewiring dephosphorylation metabolism was essential for high-level production of (+)-borneol in Saccharomyces cerevisiae, and balancing cellular dephosphorylation is also helpful for efficient biosynthesis of other terpenoids since all whose biosynthesis involves the dephosphorylation procedure.

Objective:To explore the impact of community environment on the functional ability in the elderly based on a person-environment fit perspective.Methods:The descriptive qualitative research method was used. Applying the purposive sampling method, elderly people attending two community health centers and their subordinate health stations in Beijing were selected as respondents from January to May 2024. An interview outline was developed based on the person-environment fit theory, and semi-structured interviews were used to collect information. Thematic analysis was used for data analysis.Results:A total of 16 community elderly people were interviewed, and four themes were finalized, including multidimensional compensation of the environment for individual competence (accessible and convenient environments compensate for declining motor abilities, supportive physical environments compensate for declining vision and vitality, social support compensates for declining cognitive abilities, and age-friendly environments enhancing a sense of belonging and security) , congruence of personal preferences with the community environment (diversity of activities to meet individualized needs, environmental stability to ensure a sense of control over life, age-friendly digital environments to meet the digital needs of the elderly) , personal influencing factors of the perceived environment (length of residence, personal health status, personal social relations) , and coping styles with person-environment mismatches (enhancement of individual capabilities, use of assistive devices for self-empowerment, proactive home age-friendly adaptation, self-psychological adjustment) .Conclusions:Community healthcare workers should emphasize the role of the environment and give full consideration to the individual characteristics, needs and preferences of the elderly people, and pay special attention to the elderly people who have a poor perception of the environment and encourage them to take positive coping styles to adapt to the environment.

In recent years， hyperuricemia （HUA） has shown a rapidly increasing incidence and tends to occur in increasingly young people， with a wide range of cardiac， renal， joint， and cancerous hazards and all-cause mortality associations. Western medicine treatment has limitations such as large liver and kidney damage， medication restriction， and easy recurrence. The intestine is the major extra-renal excretion pathway for uric acid （UA）， and the intestinal microecology can be regulated to promote UA degradation. It offers great potential to develop UA-lowering strategies that target the intestinal microecology， which are promising to provide safer and more effective therapeutic approaches. Traditional Chinese medicine （TCM） can treat HUA via multiple targets and multiple pathways from a holistic view， with low toxicity and side effects. Studies have shown that intestinal microecology is a crucial target for TCM in the treatment of HUA. However， its specific mechanism of action has not been fully elucidated. Focusing on the key role of intestinal microecology in HUA， this review explores the relationship between intestinal microecology and HUA in terms of intestinal flora， intestinal metabolites， intestinal UA transporters， and intestinal barriers. Furthermore， we summarize the research progress in TCM treatment of HUA by targeting the intestinal microecology， with the aim of providing references for the development of TCM intervention strategies for HUA and the direction of future research.

OBJECTIVE: To evaluate the effectiveness of the innervated medial plantar flap for reconstructing soft tissue defects, particularly in the weight-bearing zone, after resection of foot tumors. METHODS: A retrospective analysis was conducted on 12 patients with malignant skin and soft tissue tumors of the foot treated between October 2023 and December 2024. The cohort included 8 males and 4 females, aged 42-67 years (mean, 57.5 years). Tumor types comprised malignant melanoma (5 cases), squamous cell carcinoma (4 cases), arsenical keratosis (2 cases), and tumor-induced osteomalacia (1 case). Soft tissue defects located in the heel weight-bearing region in 10 cases and non-weight-bearing ankle region in 2 cases, with defect sizes ranging from 4.0 cm×3.0 cm to 6.0 cm×4.0 cm. Preoperative photon-counting CT angiography (PC-CTA) was performed to assess the medial plantar artery and its perforators. All patients underwent radical tumor resection with confirmed negative margins. The resulting defects were reconstructed using a innervated medial plantar flap incorporating sensory branches of the medial plantar nerve. The flap donor site was covered with a split-thickness skin graft harvested from the ipsilateral inguinal region. RESULTS: The operation was successfully completed in all 12 patients. All flaps survived completely without vascular compromise, partial necrosis, or total loss. Incisions healed primarily without dehiscence or infection. Minor skin graft necrosis occurred at the donor site in 3 patients, which healed within 2-3 weeks with routine dressing changes. No donor site complication (e.g., tendon or nerve injury) occurred. Patients were followed up 2-16 months (mean, 10.3 months). At last follow-up, there was no tumor recurrence. Flaps exhibited good color and texture match with surrounding tissue, restored sensation, and all feet achieved normal weight-bearing activity. CONCLUSION The innervated medial plantar flap, precisely designed based on PC-CTA localization, provides reliable blood supply and effective sensory restoration. It is an ideal method for reconstructing soft tissue defects after foot tumor resection, especially in the heel weight-bearing region.
