Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Mussel adhesive protein (MAP) is increasingly utilized in the biomedical field for the development of various bio-inspired products such as adhesives, protective films, and coatings with diverse properties, owing to its excellent biocompatibility, low immunogenicity, broad-spectrum adhesiveness, and biodegradability. The biological effects and mechanisms of MAP include adhesive film formation, cell migration and proliferation, anti-inflammatory and antioxidant activities, and inhibition of pigment formation. In dermatological applications, MAP demonstrates a significant potential in antibacterial and antipruritic effects, wound healing, barrier repair, and scar regeneration. In recent years, advances in understanding the secretion, distribution, and adhesion mechanisms of MAP, along with innovations in extraction methods, have led to the development of various natural MAP, recombinant MAP, mussel-inspired, and mussel-mimetic biomedical products. However, the biosafety, tissue compatibility, and functionality of these products remain subjects of debate. Further investigation is needed to elucidate the interactions between MAP-based products and various organ tissues and cells within complex biological systems, as well as to thoroughly evaluate their safety and efficacy. Such efforts are essential to achieve high-value utilization of MAP and to explore broader application prospects. Future research may focus on integrating MAP with emerging technologies such as nanotechnology and smart materials to further develop its multifunctional applications in the field of dermatology.

Objective:To investigate the effect of nuclear factor-erythroid 2-related factor 2 (Nrf2) gene on the proliferation and apoptosis of colorectal adenocarcinoma cells in vitro, and the role of Nrf2 gene in regulation of epithelial-mesenchymal transition (EMT) pathway.Methods:Three Nrf2 small interfering RNA (siRNA) sequences were designed and synthesized, namely siRNA-223, siRNA-538 and siRNA-756, and the unrelated sequences were designed and synthesized. The plasmids carrying various siRNA sequences of Nrf2 were constructed, and the plasmids carrying siRNA sequences and the plasmids carrying unrelated sequences were transfected into human colorectal adenocarcinoma Caco-2 cells, namely interference group and empty vector group, respectively. Additionally, Caco-2 cells without any treatment were used as the control group. Real-time fluorescence quantitative polymerase chain reaction (RT-qPCR) and Western blotting (WB) methods were used to detect the relative expression of Nrf2 gene in transcription and translation levels in each group of cells, in order to verify the interference effect of Nrf2; the siRNA with the best interference effect was selected for subsequent experiments. CCK-8 method was used to detect the proliferation ability of each group of cells (expressed as absorbance value); RT-qPCR was used to detect the relative expression of EMT pathway-related factors [vimentin (Vim), N-cadherin (N-cad) and E-cadherin (E-cad)] in transcription level in each group of cells; WB method was used to detect the expression of pro-apoptotic protein Bax in each group of cells.Results:The results of RT-qPCR and WB methods showed that compared with the control group and the empty group, the relative expression of Nrf2 gene in transcription and translation levels in Caco-2 cells of the siRNA-756 interference group were the lowest, and the differences were statistically significant (all P < 0.05). The CCK-8 results showed that the absorbance values of Caco-2 cells in the control group, empty group and siRNA-756 interference group after 48 hours of culture were (100±5)%, (94±4)% and (82±5)%, respectively; compared with the control group and the empty group, the siRNA-756 interference group had lower absorbance value, and the differences were statistically significant (all P < 0.05). The results of RT-qPCR method showed that the relative expression of Vim and N-cad in transcription level in the siRNA-756 interference group were higher than those in the control group and the empty vector group, and the differences were statistically significant (all P < 0.05); the relative expression of E-cad in transcription level was lower than those in the control group and the empty vector group, and the differences were statistically significant (both P < 0.05). The results of WB method showed that the relative expression of Bax protein in the siRNA-756 interference group was higher than that in the control group, and the difference was statistically significant ( P < 0.05). Conclusions:Interference with Nrf2 expression in vitro can weaken the proliferation and anti-apoptotic abilities of human colorectal adenocarcinoma Caco-2 cells. The mechanism may be that Nrf2 regulates the expression of Vim, N-cad and E-Cad in the EMT pathway to enhance the EMT ability of tumor cells.

Objective To explore the efficacy of the geriatric interdisciplinary team(GIT)service for elderly patients with multimorbidity and malnutrition.Methods We selected 109 elderly patients with diabetes mellitus(DM),chronic obstructive pulmonary disease(COPD)or chronic heart failure(CHF)and multi morbidity to the Department of Geriatrics of The 2nd People's Hospital of Kunming City from January 2022 to January 2023.The patients were randomly divided into the control group of 53 cases and the observation group of 56 cases.The control group received routine management of multimorbidity and malnutrition,while the observation group used the GIT service model to manage multimorbidity and malnutrition.The disease,nutritional status,and quality of life outcomes of the two groups of elderly patients were evaluated before and 3 months after the intervention.(1)HbA1c was detected in patients with DM in both groups,and the aggravation of patients with COPD or CHF was observed and recorded.(2)Nutrition-related indicators(Tp,ALB and Hb)and Barthel index were evaluated in both groups.Results(1)The HbA1c of patients with DM in the two groups decreased after intervention(P＜0.001),and the decrease in the observation group was more significant than that in the control group(P＜0.001).(2)The number of AECOPEs in patients with COPD in the two groups decreased,and the observation group was less than the control group(P＜0.05).(3)The number of CHF acute exacerbations in patients with CHF in the two groups decreased and the observation group was fewer than the control group(P＜0.05).(4)The TP,ALB,Hb and Barthel index scores of the two groups increased compared with those before intervention,and the observation group increased more significantly than the control group(P＜0.05).Conclusion The geriatric interdisciplinary team service for the elderly has a good effect in the intervention of elderly patients with multimorbidity and malnutrition.

Objective:To explore the feasibility and clinical effect of the infrared vascular imager in the transplantation of free arterialized venous flaps.Methods:A retrospective analysis was conducted with patient data of hand microsurgery using free arterialized venous flaps to repair hand wounds in the Second Affiliated Hospital of Wenzhou Medical University from March 2019 to November 2020. An arterialized venous flap was designed according to the Goldschlager’s Type Ⅲ flap design with the aid of a magnifying glass following the venous course. The flap was transfer to cover the wound of the recipient area. The reconstructive effect was observed postoperatively, including the blood supply, color, texture, survival of the flap, the flexion and extension of the affected finger, and the appearance of the forearm donor site. The hand function was evaluated by the Chinese Medical Association Hand Surgery Society’s upper limb function evaluation trial standard.Results:A total of 17 patients were included, including 11 males and 6 females, ranging in age from 19 to 68 years old, with an average age of 34.6 years. A total of 18 skin flaps were designed and elevated, and the flap size ranged from 2.0 cm × 3.0 cm to 8.0 cm × 9.0 cm. The patients were followed up 3 to 12 months after the operation, with an average follow-up of 6 months. Blisters appeared on the second day after the operation in 8 flaps, and the affected limbs were raised to maintain the integrity of the blisters. The blisters of the flaps subsided one week after the operation. Congestion occurred on the second day after operation in 7 flaps, which subsided after two weeks after routine treatment, such as raising the affected limb and removing some sutures. One flap developed progressive hypoperfusion one week after the operation, and eventually necrosis. Seventeen flaps survived, and one flap failure was observe. All the surviving skin flaps were free of bloat and had a good appearance. In two cases, the skin graft area was pigmented, and the flexion and extension activities of the affected fingers were suitable. Using the Chinese Medical Association Society of Hand Surgery’s upper limb function evaluation trial standard, 16 patients (excluding one flap failure) were evaluated for hand function, showing 11 cases were excellent and 5 cases were good.Conclusions:Infrared vascular imaging technology enables free arterialized venous flap transplantation to realize non-contact, non-invasive, simple operation, intuitive and accurate, and truly realizes rapid flap design under direct vision. Infrared vascular imaging technology is an effective auxiliary tool for free arterialized venous flap transplantation.

In order to screen African swine fever virus (ASFV) diagnostic antigen with the best enzyme linked immunosorbent assay (ELISA) reactivity. By establishing the ELISA method, the diagnostic antigen of ASFV p30 protein expressed by baculovirus-insect cell expression system as reference, we explored the antigenic properties and diagnostic potential of ASFV p35 protein expressed by prokaryotic expression system as a diagnostic antigen. The results of Western blotting and immunofluorescence show that the molecular weight of the recombinant p35 protein and p30 protein obtained was 40 kDa and 30 kDa, respectively, and these two proteins had good immuno-reactivity with ASFV positive serum. Recombinant p30 and p35 proteins were used as diagnostic antigens to establish ELISA, and the sensitivity and repeatability of these methods were tested. The results show that although the detection sensitivity of the p30-ELISA established in this study was higher than that of the p35-ELISA, the sensitivity of p35-ELISA was 95.8%, and variations in intra- and inter-assay repeatability of the two methods were less than 10%. The coincidence rate between the p35-ELISA and the imported kit was 97.2%. Results show that p35-ELISA was sensitive and stable, and could detect specific antibodies against ASFV.
