As a neglected tropical disease, schistosomiasis remains a major public health challenge in underdeveloped areas, notably Africa. Currently, the national schistosomiasis control programmes in Africa mainly depend on foreign aids; however, conventional international aid models have multiple limitations. To enhance the effectiveness and sustainability of global schistosomiasis control programmes, this article proposes a trinity collaboration model based on international rules, China’s experiences and local needs, which is explained with China aid project of schistosomiasis control in Zanzibar as an example. Based on the successful experiences from the national schistosomiasis control programme in China, this model emphasizes the compliance with World Health Organization guidelines and fully considers local actual needs to promote the effectiveness and sustainability of the schistosomiasis control programme through integrating international resources and promoting China’s experience to meet local needs. The successful practice of the China aid project of schistosomiasis control in Zanzibar provides strong evidence that the model is of great theoretical significance and practical value to improve the efficiency of multilateral collaboration and promote global health governance.

Objective:To explore the possibility of using a inferior gluteal artery perforator flap (IGAPF) for breast reconstruction in the patient who did not have suitable donor site in back and abdomen.Methods:In November 2024, a 25-year-old unmarried and childless woman with right breast cancer received immediate right breast reconstruction by a right free IGAPF after modified right mastectomy in the Department of Breast and Thyroid Surgery, Second Affiliated Hospital of Hainan Medical University. The locations of perforators were confirmed by both Multi-detector computed tomography angiography (MDCTA) and portable Doppler blood flow detector before surgery. The IGAPF was designed to take the inferior gluteal wrinkle as the lower edge, the axis of the flap was parallel to the inferior gluteal wrinkle, and the width of the flap was estimated where the incision could be directly closed. The size of right IGAPF was 6.0 cm×19.0 cm. Sharp dissection was performed between the sarcolemma and muscle fibres of gluteus, then the perforators were dissected along the direction of muscle fibres of gluteus. The vascular pedicle was kept at about 8.0 cm in length. The diameter of artery was about 2.0 mm and that for the veins was about 1.5 mm. End-to-end anastomoses with the right thoracodorsal artery and vein were successfully carried out. The donor site was directly closed, and it was hidden in the inferior gluteal wrinkle. Postoperative outpatient clinical review was made.Results:Pathological examination reported: an invasive carcinoma of right breast, axillary lymph node metastasis (2/10). The patient recovered well and the flap survived without any complication, i.e. ischemic necrosis, infection and haematoma. The patient was off-bed at 3 days and discharged at 13 days after surgery. At the 40 days of postoperative follow-up, the patient achieved a good recovery and the lower limb activity was not affected by the surgery. The patient was satisfied with the reconstructed breast and donor site recovery. The patient followed with scheduled chemotherapy and subsequent radiotherapy. The volume of reconstructed breast was smaller than the other breast, of which the patient was fully informed before the surgery.Conclusion:A free IGAPF provides an alternative donor sites for achieving a breast reconstruction due to the reliable pedicle vessels and invisible donor scars.

Objective:To analyze the value of marginal donor livers in liver transplantation for patients with acute-on-chronic liver failure (ACLF).Methods:Clinical data of 58 patients with ACLF undergoing liver transplantation at the First Affiliated Hospital of Guangxi Medical University from January 2020 to June 2023 were retrospectively analyzed, including 33 males and 25 females, aged (40.4±14.4) years. According to the source of donor (marginal or standard), recipients were divided into the marginal group ( n=28), and standard group ( n=30). The preoperative model for end-stage liver disease (MELD) score, cold/warm ischemia time, intraoperative blood loss, postoperative tracheal intubation time, intensive care unit (ICU) stay, liver function, renal function, coagulation function, postoperative complications, and survival situation were compared between the groups. Results:The MELD score, cold/warm ischemia time, intraoperative blood loss, postoperative tracheal intubation time, length of ICU stay, alanine transaminase, aspartate transaminase, total bilirubin, serum creatinine, blood urea nitrogen, estimated glomerular filtration rate, fibrinogen, postoperative infection, primary graft nonfunction, biliary complications, and vascular complications were compared between the groups (all P>0.05). The incidence of delayed graft function (DGF) recovery was 28.6%(8/28) in marginal group, higher than that in standard group 6.7%(2/30) ( χ2=5.13, P=0.038). The one-year cumulative survival rates were 89.3% and 93.3% in marginal group and standard group, respectively ( P=0.580). Conclusion:The therapeutic effect of marginal donor liver in ACLF recipients is comparable to that of standard donor liver. The incidence of DGF is higher in recipients with marginal donor liver.

Under the background of carbon peaking and carbon neutrality goals, the Ministry of Ecology and Environment, together with 15 national ministries and commissions, has formulated the Implementation Plan on Establishing a Carbon Footprint Management System, and it is urgent for traditional Chinese medicine(TCM) pharmaceutical enterprises to carry out research on carbon footprint accounting methods of related products. Based on the life cycle assessment(LCA) theory, taking mulberry leaf extract produced by a certain enterprise as an example, this study analyzed the carbon footprint of TCM extracts during the life cycle. The results show that for every 1 kg of product produced, the carbon emissions from the stages of raw material acquisition, transportation, and extract production are-20.569, 1.205, and 173.577 kgCO_2eq(CO_2 equivalent), respectively. The carbon footprint of the product is 154.213 kgCO_2eq·kg~(-1). In addition, the carbon emission is the highest in the production stage, in which the consumption of ethanol solvents makes the greatest contribution to the carbon footprint, accounting for 25.71%, more than one-fourth of the total carbon footprint. The second contribution was from the treatment process of TCM residues, accounting for 19.67%, closely followed by wastewater treatment(17.71%), the consumption of hot steam(17.43%), and drinking water(16.90%). The consumption of electric power and packaging materials has a smaller carbon emission of 2.58%. In particular, the carbon emission caused by the consumption of packaging materials is only 0.04%, which is negligible. The results of the study are expected to provide a reference for TCM enterprises to carry out research on the carbon footprint of products, offer ideas for collaborative innovation in reducing pollution and carbon emissions throughout the entire industry chain of TCM, and develop new quality productivity of modern TCM industry based on green and low-carbon manufacturing.

Coronavirus-related diseases pose a significant challenge to the global health system. Given the diversity of coronaviruses and the unpredictable nature of disease outbreaks, the traditional "one bug, one drug" paradigm struggles to address the growing number of emerging crises. Therefore, there is an urgent need for therapeutic agents with broad-spectrum anti-coronavirus activity. Here, we provide evidence that ATV006, an anti-SARS-CoV-2 nucleoside analog targeting RNA-dependent RNA polymerase (RdRp), has broad antiviral activity against human and animal coronaviruses. Using mouse hepatitis virus (MHV) and human coronavirus NL63 (HCoV-NL63) as a model, we show that ATV006 has potent prophylactic and therapeutic activity against murine coronavirus infection in vivo. Remarkably, ATV006 successfully inhibits viral replication in mice even when administered 96 h after infection. Due to its oral bioavailability and potency against multiple coronaviruses, ATV006 has the potential to become a useful antiviral agent against SARS-CoV-2 and other circulating and emerging coronaviruses in humans and animals.

Tauopathies, including Alzheimer's disease (AD), are a series of neurodegenerative diseases characterized by pathological accumulation of the microtubule-associated protein tau. Since the abnormal modification and deposition of tau in nerve cells are crucial for tauopathy etiology, methods for reducing tau levels, such as promoting tau degradation, may become effective strategies for disease treatment. Herein, we identified that sorafenib significantly reduced total tau and phosphorylated tau levels through screening FDA-approved drugs. We showed that sorafenib treatment attenuated cognitive deficits and tau pathologies in PS19 tauopathy model mice. Mechanistically, we found that sorafenib inhibited multiple kinases involved in tau phosphorylation and promoted autophagy. Importantly, we further demonstrated that sorafenib also promoted the expression of the E3 ubiquitin ligase FBXW7, which could bind tau and mediate tau degradation through the ubiquitin-proteasome pathway. Finally, we showed that FBXW7 expression decreased in the brains of AD patients and tauopathy model mice, and that overexpression of FBXW7 in the hippocampus attenuated cognitive deficits and tau pathologies in PS19 mice. These results suggest that sorafenib may be a promising treatment option for tauopathies by promoting tau degradation and reducing tau phosphorylation, and that targeting FBXW7 could also serve as an alternative therapeutic strategy for tauopathies.
