ObjectiveTo construct a comprehensive evaluation indicator system for clinical practice guidelines of traditional Chinese medicine （TCM） that is scientific， systematic， and reflects the characteristics of TCM. MethodsA systematic search was conducted in Chinese and English databases， including CNKI， Wanfang， VIP， SinoMed， PubMed， Embase， and Cochrane Library， to include literature on domestic and international guideline evaluation tools and TCM-related research. Document analysis and CiteSpace were utilized for keyword co-occurrence and clustering analysis. ResultsA total of 65 relevant studies were included， from which seven core thematic domains were identified. Based on the research objectives， a two-step construction strategy was adopted： first， an external evaluation framework was established by referencing international tools to cover methodological rigor and procedural standardization； second， an internal evaluation framework was developed to reflect the distinctive features of TCM clinical practice， including syndrome differentiation and efficacy feedback. Through expert consensus， the indicator system was refined， resulting in a dual-layered structure comprising 8 primary indicators， 22 secondary indicators， and 62 evaluation criteria. ConclusionThe comprehensive evaluation system for TCM clinical practice guidelines， based on bibliometric analysis and core element extraction， integrates both theoretical integrity and practical applicability. This study provides a preliminary research foundation for further optimization， validation， and development of a refined comprehensive evaluation system.

The paper introduces Professor LIU Xing's clinical experience and characteristics of integrative acupuncture and medication in treatment of primary trigeminal neuralgia (PTN). It is believed that the essential pathogenesis of PTN is pathogenic wind, and qi and blood obstruction results from invasion of pathogenic wind. Hence, dispelling wind is the key principle of treatment. Palpation is done at first in the neck, face and buccal mucosal region to detect the masses in treatment. Acupotomy is operated at the masses distributed at Shangguan (GB3), Xiaguan (ST7) and the white line of buccal mucosa, so as to release masses. Additionally, five-wind points (Fengfu [GV16], bilateral Fengchi [GB20], Yifeng [TE17], Bingfeng [SI12] and Fengmen [BL12]), three-nape points (bilateral Naokong [GB19], Tianzhu [BL10] and Jianjing [GB21]) and three-governor-vessel points (Baihui [GV20], Zhiyang [GV9] and Yintang [GV24⁺]) are selected to dispel wind and stop pain. Besides, herbal decoction (wu feng tang) and blood-letting at ear apex are administered in combination. The integration of acupuncture and medication obtains a holistic effect on PTN by dispelling wind pathogen, and promoting qi and blood circulation.

Metastatic dissemination is the major cause of death from breast-cancer (BC). Fusobacterium nucleatum (F.n) is widely enriched in BC and has recently been identified as one of the high-risk factors for promoting BC metastasis. Here, with an experimental model, we demonstrated that intratumoral F.n induced BC aggressiveness by transcriptionally activating Epithelial-mesenchymal transition-associated genes. Therefore, the F.n may be a potential target to prevent metastasis. Given the fact that cancer-associated fibroblasts (CAFs) are abundant in BC and located near blood vessels, we report an optogenetic system that drives CAF to in situ produce human antibacterial peptide LL37, with the characteristics of biosafety and freely intercellular trafficking, for depleting intratumoral F.n, leading to a 72.1% reduction in lung metastatic nodules number without affecting the balance of the systemic flora. Notably, mild photothermal treatment was found that could normalize CAF, contributing to synergistically inhibiting BC metastasis. In addition, the system can also simultaneously encode a gene of TNF-related apoptosis-inducing ligand to suppress the primary tumor. Together, our study highlights the potential of local elimination of tumor pathogenic bacteria to prevent BC metastasis.

Alzheimer's disease (AD) is the most prevalent neurodegenerative disorder worldwide, causing dementia and affecting millions of individuals. One prominent characteristic in the brains of AD patients is glucose hypometabolism. In the context of galactose metabolism, intracellular glucose levels are heightened. Galactose mutarotase (GALM) plays a crucial role in maintaining normal galactose metabolism by catalyzing the conversion of β-D-galactose into α-D-galactose (α-D-G). The latter is then converted into glucose-6-phosphate, improving glucose metabolism levels. However, the involvement of GALM in AD progression is still unclear. In the present study, we found that the expression of GALM was significantly increased in AD patients and model mice. Genetic knockdown of GALM using adeno-associated virus did not change the expression of amyloid precursor protein (APP) and APP-cleaving enzymes including a disintegrin and metalloprotease 10 (ADAM10), β-site APP-cleaving enzyme 1 (BACE1), and presenilin-1 (PS1). Interestingly, genetic overexpression of GALM reduced APP and Aβ deposition by increasing the maturation of ADAM10, although it did not alter the expression of BACE1 and PS1. Further electrophysiological and behavioral experiments showed that GALM overexpression significantly ameliorated the deficits in hippocampal CA1 long-term potentiation (LTP) and spatial learning and memory in AD model mice. Importantly, direct α-D-G (20 mg/kg, i.p.) also inhibited Aβ deposition by increasing the maturation of ADAM10, thereby improving hippocampal CA1 LTP and spatial learning and memory in AD model mice. Taken together, our results indicate that GALM shifts APP processing towards α-cleavage, preventing Aβ generation by increasing the level of mature ADAM10. These findings indicate that GALM may be a potential therapeutic target for AD, and α-D-G has the potential to be used as a dietary supplement for the prevention and treatment of AD.

Objective:To explore the related risk factors contributing to re-fracture after hip surgery in elderly patients.Methods:This retrospective analysis was conducted on the clinical data of 2 415 elderly individuals who underwent surgical treatment for hip fractures and were discharged from Shanghai Sixth People's Hospital between January 2016 and December 2021.Patients were grouped into re-fracture and non-re-fracture cohorts based on whether a second fracture occurred within three years after surgery.Demographics, clinical data, and postoperative functional rehabilitation outcomes of the two groups were collected, and univariate and multivariate logistic regression analyses were applied to identify the independent risk factors for re-fractures after surgery.Results:A total of 2, 000 patients who completed follow-up were included in the final analysis, aged 60~91 years, with a mean age of (75.4±8.2) years.Among them, 855 were male(42.75%), and the postoperative re-fracture incidence was 28.25% (565/2 000). Univariate analysis indicated that advanced age, fracture type at first onset, lower Harris scores, insufficient rehabilitation training, osteoporosis, diabetes, cerebrovascular disorders, visual impairment, and syncope were all significantly associated with re-fracture (all P<0.05), while gender differences were not statistically significant ( P>0.05). Multivariate regression confirmed the following as independent risk factors: age ≥75 years, postoperative Harris score <80, non-standard rehabilitation training, combined osteoporosis, diabetes, cerebrovascular disease, visual impairment, and syncope ( OR、 RR>1). Conclusions:Elderly patients are prone to re-fracture after hip surgery, and its occurrence is closely related to advanced age, inadequate functional rehabilitation, osteoporosis, and multiple internal medical comorbidities.In clinical practice, attention should be paid to standardized postoperative rehabilitation, systematic anti-osteoporotic therapy, and active intervention of comorbidities to reduce the incidence of re-fracture and improve the long-term prognosis of patients.

Objective:To screen broadly neutralizing antibodies in human immunodeficiency virus-1（HIV-1）chronically infected individuals and characterize their molecular features and to provide new strategies for rational vaccine development and antibody-based therapeutics.Methods:A total of 34 treatment-na?ve individuals with chronic HIV-1 infection were enrolled. Plasma antibody binding levels were measured against two HIV-1 envelope proteins. Single antigen-specific memory B cells were sorted from high-binding samples，and antibody variable region genes were amplified by PCR for paired expression. The monoclonal antibodies were evaluated for neutralizing activity using pseudovirus assays，and their structural features were analyzed by integrating AlphaFold 3 prediction with Discovery Studio molecular docking.Results:Plasma samples showed strong binding to DU422-GP140 and BG505-GP140. Eight monoclonal antibodies were isolated from two donors. Among them，antibodies 0919-A4，0919-A9 and 0808-A2 could cross-react with GP140 from HIV-1 subtypes AE，BC and B. The monoclonal antibody 0919-A9 demonstrated potent neutralizing activity against SF162（Tier 1）and CH181（Tier 2）pseudoviruses，with somatic hypermutation rates of 13.27%（heavy chain）and 15.58%（light chain）. Structural modeling revealed its specific targeting of the V1V2 region on GP120.Conclusion:The isolated antibody 0919-A9 effectively neutralizes Tier 2 pseudoviruses. Its high somatic mutation frequency and V1V2-targeting property underlie its neutralizing activity，providing both a promising candidate and mechanistic insights for HIV vaccine development and antibody-based therapeutic strategies.

Objective:To explore the clinical efficacy of anterolateral thigh perforator flap (ALTPF) in treatment of extensive wound of Degree IV burns in limbs.Methods:A retrospective analysis was conducted on 9 patients who had extensive wound of Degree IV burns in limbs caused by stove burns admitted to Department of Burns and Plastic Surgery, the 988th Hospital of the Joint Logistics Support Force of the Chinese PLA between January 2017 and January 2024. Among the patients, there were 8 males and 1 female, aged between 36 and 63 years. Three patients had the wound from anterior leg to dorsal foot, 3 from leg down to ankle, 1 from forearm to hand and 2 from arm to forearm. Area of burns ranged from 20 cm × 15 cm to 30 cm × 25 cm, and all patients were treated by free ALTPF. According to whether the main artery at the recipient site was feasible for direct anastomosis with the vessels carried in flap, 4 patients were treated by bilateral parallel ALTPFs, and 5 were treated by unilateral ultra-long internally supercharged ALTPF. A total of 13 ALTPFs were harvested, with individual flap size at 20 cm × 8 cm to 46 cm × 12 cm. Donor sites were directly sutured. Time for flap harvesting, flap survival and wound healing time were records. Scheduled postoperative follow-up was conducted at outpatient clinic and via telephone interviews to evaluate functional recovery. Follow-up assessments included evaluation of flap condition, two-point discrimination (TPD), recovery of joint function at recipient sites, flap appearance and donor site recovery.Results:The time for flap harvest was 1.0 to 4.5 hours. All 13 ALTPFs successfully survived. The time from surgery to healing of recipient sites was 18 to 72 days, and all donor sites healed. Over the postoperative follow-up that lasted for 6 to 34 months, the recipient sites had found with good cosmetic outcomes, without osteomyelitis or deep tissue infection. Four ALTPFs in 2 patients were found swelling, which were revised at 6 months after surgery. Four ALTPFs in other 2 patients had pigment deposition at edges. One ALTPF was scalded, which healed after dressing changes but left with patchy scars. The remaining ALTPFs were soft, elastic, free from pain and well-perfused, with regained protective sensation at S 3. However, all of the ALTPFs failed to detect TPD. Six patients with lower limb injuries were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) ankle hindfoot scoring system: 2 patients were rated as excellent and 4 were rated as good. Three patients with upper limb injuries were evaluated using Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association: 1 patient was rated as excellent and 2 were rated as good. Only linear scars left at the 13 donor sites, with normal blood supply to the distal limbs, and without restrictions in range of motion of knee joints nor muscle strength of quadriceps. Conclusion:The ALTPF offers advantages such as anatomical consistency, reliable blood supply and flexible combination in treatment of extensive wound of Degree Ⅳ burns in limbs. It is an ideal surgical procedure for treatment of large soft tissue defects of extremities.

Objective:To explore the clinical efficacy of the first dorsal metatarsal artery pedicled lateral toe bilobed flap in repairing the finger pulp defects of two adjacent fingers.Methods:This study was a retrospective observational study. From January 2018 to December 2022, 9 patients with finger pulp defects in two adjacent fingers who met the inclusion criteria were admitted to the Department of Burns and Plastic Surgery of the 988 th Hospital of Joint Logistics Support Force of PLA, including 6 males and 3 females, aged 26 to 48 years. The injured fingers were the index finger and middle finger (5 cases) or the middle finger and ring finger (4 cases). After debridement, the wound area of a single finger ranged from 1.2 cm×0.8 cm to 3.2 cm×2.8 cm. The finger pulp defects of two adjacent fingers were repaired with the first dorsal metatarsal artery pedicled lateral toe bilobed flap, and the two adjacent fingers were sutured together. The area of single flap ranged from 1.5 cm×1.0 cm to 3.5 cm×3.0 cm. The wound in the flap donor site was sutured directly or repaired with full-thickness skin graft from the groin region. The finger separation surgery was performed 3 weeks after surgery. The survival and blood supply of flaps, and survival of skin grafts and wound healing of the donor sites were observed after surgery. During follow-up, the texture, sliding, and shape of the flap, movement function of the finger, and the shape and function of the foot donor site were observed. At the last follow-up, the sensory of the flap was evaluated according to the sensory evaluation standard of the British Medical Research Council, and the hand function was evaluated according to the functional evaluation trial standard for severed finger replantation of the Hand Surgery Society of the Chinese Medical Association. Results:After surgery, all the flaps of 9 patients survived without vascular crisis. The flaps were soft in texture and good in shape. One patient had partial necrosis at the edge of the skin graft in the toe, and the wound healed after dressing change; the skin grafts in the toe in the other 8 patients survived, and the wounds healed well. During follow-up of 12 to 18 months after surgery, the flaps had soft texture, good elasticity, low sliding, and good shape. The finger movement function was normal. The wound in foot donor site recovered well without ulceration and deformity, and walking was not affected. At the last follow-up, the sensation of the flaps was sensitive, of which 8 flaps reached S3 and 10 flaps reached S3 + in sensation, and the two-point discrimination distance of the flaps was 9-13 mm. The functional scores of the affected fingers were 85 to 95, all of which were excellent. Conclusions:The first dorsal metatarsal artery pedicled lateral toe bilobed flap can repair finger pulp defects of two adjacent fingers at the same time, and the appearance, sensation, and function of the affected fingers recovered well after surgery, with less damage to the foot donor site. It is one of good methods to repair finger pulp defects of two adjacent fingers in clinic.

BACKGROUND:Chondrocyte apoptosis is an important factor in the development of osteoarthritis,and Complanatoside A has a flavonoid effect,which can inhibit apoptosis of various cells,but its effect on chondrocyte apoptosis and the mechanism of action are not clear. OBJECTIVE:To investigate the intrinsic association and mechanism of Complanatoside A in chondrocyte apoptosis based on the Wnt/β-catenin signaling pathway. METHODS:(1)The cartilage tissues of the femur and tibia transected during knee arthroplasty were collected,and chondrocytes were isolated,cultured in vitro,and identified.(2)Cell counting kit-8 was used to detect the optimal intervention concentration of Complanatoside A in the concentration range of 0-160 μmol/L.(3)Chondrocytes were divided into blank group,sodium nitroprusside(1.5 mmol/L)-induced group,and sodium nitroprusside(1.5 mmol/L)+Complanatoside A(5 μmol/L)group.The viability and apoptosis rate of the cells in each group were detected by cell counting kit-8 and flow cytometry.The expression of type Ⅱ collagen and SOX9 was detected by immunofluorescence staining.The expression of apoptosis-related proteins and Wnt/β-catenin pathway proteins was detected by western blot assay. RESULTS AND CONCLUSION:The cells extracted in vitro were cultured and stained,and were clearly identified as chondrocytes.Complanatoside A had no obvious cytotoxicity to chondrocytes in the concentration range of 0-80 μmol/L,and significantly improved the chondrocyte viability in the concentration range of 2.5-10 μmol/L,especially when the concentration was 5 μmol/L.The apoptotic rate of chondrocytes was higher in the sodium nitroprusside-induced group than the blank control group,while the apoptotic rate was lower in the sodium nitroprusside+Complanatoside A group than the sodium nitroprusside-induced group.The fluorescence intensity of type Ⅱ collagen and SOX9 in chondrocytes was weaker in the sodium nitroprusside-induced group than the blank control group,while the fluorescence intensity of type Ⅱ collagen and SOX9 in the sodium nitroprusside+Complanatoside A group was higher than that of the sodium nitroprusside-induced group.In the sodium nitroprusside-induced group,the protein expression of Bax,Caspase-3,matrix metalloproteinase 13,Wnt3a,Wnt5a and β-catenin was higher than that of the blank control group,while the protein expression of Bcl-2 was lower than that of the blank control group.In the sodium nitroprusside+Complanatoside A group,except for the protein expression of Bcl-2 which was higher than that of the sodium nitroprusside-induced group,the expression of the other aforementioned proteins was lower than that of the sodium nitroprusside-induced group.To conclude,Complanatoside A has a certain inhibitory effect on chondrocyte apoptosis,which could regulate apoptosis-related proteins and promote the expression of chondrocyte regulatory factors,and presumably might play a role through inhibiting the Wnt/β-catenin signaling pathway.

Objective To explore the anti-inflammatory properties of the ethyl acetate extract(ETCB)derived from Trollius chinensis Bge.using in vitro RAW264.7 cells stimulated with lipopolysaccharide and an in vivo mouse auricle model induced by xylene.Utilizing UHPLC-Q-TOF-MS(LC-MS)and network pharmacology,the components of ETCB were analyzed,and its anti-inflammatory mechanisms were preliminarily explored.Methods The anti-inflammatory activity of various solvent extracts of Trollius chinensis Bge.was assessed through the Griess assay.The impact of ETCB on the production of TNF-α and IL-6 in RAW264.7 cells induced by lipopolysaccharide was evaluated using ELISA.Real-time qPCR was conducted to determine the effect of ETCB on the expression levels of inflammatory factors such as TNF-α,IL-6,and iNOS in cells.The anti-inflammatory efficacy was further validated in a xylene-induced ear inflammation mouse model by measuring ear swelling and tissue levels of IL-6 and TNF-α.The composition of ETCB was analyzed using LC-MS.Network pharmacology was employed to screen for effective components,targets,and pathways involved in the anti-inflammatory effects of Trollius chinensis Bge.,followed by molecular docking verification between core components and targets.Results ETCB demonstrated the most potent inhibitory effect on NO production in RAW264.7 cells stimulated by lipopolysaccharide,indicating its primary role in the anti-inflammatory activity of Trollius chinensis Bge..ETCB significantly reduced TNF-α and IL-6 levels in inflammatory cells(P<0.01)and inhibited the mRNA expression of TNF-α,IL-6,and iNOS.In the xylene-induced mouse ear inflammation model,ETCB effectively alleviated ear swelling and decreased tissue levels of TNF-α and IL-6.LC-MS analysis identified 30 chemical components in ETCB,including 21 flavonoids,7 organic acids,1 polysaccharide,and 1 anthocyanin.Network pharmacology prediction and screening revealed TNF,Akt1,PTGS2,EGFR,SRC,and MMP9 as core targets,with hydroxyquercetin,lignin from fragrant leaves,zeaxanthin from willows,plantain,thistle,and sophora flavins as key anti-inflammatory active ingredients.The molecular docking analysis revealed positive interactions,characterized by favorable binding energy,between the active components and key targets.Conclusion ETCB demonstrates strong anti-inflammatory properties both inside and outside the body,functioning through various targets and pathways.This establishes a basis for deeper understanding of the anti-inflammatory mechanism of Trollius chinensis Bge.
