    Abstract A major strategy for addressing the imbalance in source-network-load distribution is interprovincial electricity transmission; however, this process also causes various environmental effects. Previous studies have mainly examined thermal power transmission, and few insights have been gained into the challenges hydroelectricity transmission poses for biodiversity conservation. Here, we innovatively incorporated the freshwater species diversity footprint into a hydropower environmental impact assessment, calculating the interprovincial transfer of freshwater species diversity embodied in hydroelectricity transmission. We proposed an evaluation model of an interprovincial hydroelectricity transmission network using freshwater species diversity as the ecological element and creatively identified significant nodes and paths of the network. Up to 28% of the transfer of freshwater species diversity was related to the demand for hydroelectricity consumption in Shanghai. 64% of the relationships in the hydroelectricity transmission network were implemented at the expense of ecological losses on one side. Shanghai and Sichuan provinces and some transmission lines related to them were significant nodes and paths for improving the overall status of the network. This research can help policymakers comprehend the challenges to freshwater species presented by interprovincial hydroelectricity transmission and serve as a reference for ecological compensation for hydropower development.

    Abstract Driven by the global net-zero carbon emission goal, even though the impact of hydropower on river ecosystems cannot be ignored, hydropower scale and intensity will be expanded in Southwest China (SC). Therefore, the trade-off between hydroelectricity generation and ecological protection remains an issue requiring urgent attention at the moment. This paper proposes an eco-efficiency (EE) indicator system of hydropower adopting the water consumption of hydropower product (PWC), labor, and capital as inputs and the power generation, ecological flow deviation (EFD) as outputs and then explores the factors influencing the EE value of hydropower in SC. The results indicate that (1) The EE incorporates the impact of each plant on fish, provides decision support for hydropower development planning and serves as the foundation for eco-dispatch operations. (2) Hydropower generation affects fish reproduction in SC, and the EE value of the Wu River is relatively low. (3) The scale of power generation and degree of fish protection are two significant factors that can increase the EE value of hydropower. To compensate for plant inadequacies in these two aspects, equivalent changes in hydropower planning and eco-dispatch operations should be implemented.

    Abstract Emerging contaminants such as nanoplastics (NPs) and per- and polyfluoroalkyl substances (PFAS), have been detected in the environment and breast milk, thus exposing infants to potentially harmful chemicals during breastfeeding. Breast milk contains secretory immunoglobulin A (SIgA), an antibody that plays a vital role in disease protection and the development of the infant's immune system. This study employed molecular simulation and fractional factorial designs to assess the toxicity of NPs and PFAS on breast milk and their influence on infant immunity by inhibiting SIgA. The research found that NPs and PFAS have higher binding affinities to SIgA compared to the control compound. Polycarbonate (-10.7 kcal/mol) had the highest binding affinity among plastics, while Perfluorodecanoic acid (PFDA, - 8.0 kcal/mol) had the highest binding affinity among PFAS. The relative toxic index was higher for PFAS (2.4) than for plastics (1.9), suggesting that PFAS may pose a higher overall toxicity burden on the protein. The presence of specific combinations of NPs and PFAS in breast milk may potentially harm breastfeeding infants, although additional experimental studies are required to validate these findings. These results underscore the potential risks associated with these emerging contaminants in breast milk and their impact on infant immunity.

    Abstract Due to the COVID-19 pandemic, Bangladesh government took the measure like partial lockdown (PL) and complete lockdown (CL) to curb the spread. These measures gave a chance for environmental restoration. In this study, street dust samples were collected during PL and CL from four main urban land use categories in Dhaka city, such as industrial area (IA), commercial area (CA), public facilities area (PFA), and residential area (RA). Ten potentially toxic elements (Cr, Mn, Zn, Fe, Pb, Cu, Co, Ni, As, and Cd) in fine street dust particles (diameter < 20 μm) were determined following aqua-regia digestion and measured by inductively coupled plasma mass spectrometry (ICP-MS) to evaluate distribution, pollution sources, and potential risks to ecological systems and human health. Results showed that during PL, the concentrations of toxic elements in the dust were higher than that of CL. Cd and Fe were lowest and highest in concentration with 1.56 to 41,970 µg/g and 0.82 to 39,330 µg/g in partial and complete lockdown period respectively. All toxic elements were detected at high levels above background values where Fe with the highest and Cd with lowest concentrations, respectively. By land use, the levels of toxic elements pollution followed IA > PFA > RA > CA. Correlation analysis (CA), principal component analysis (PCA), and hierarchal cluster analysis (HCA) revealed that the sources of these analyzed toxic elements were mainly from anthropogenic which are related to industrial and vehicular or traffic emissions. Enrichment factor (EF), geoaccumulation index (Igₑₒ), contamination factor (CF), and pollution load index (PLI) also suggested that the dust was more polluted during PL. Exposure of toxic elements to human was mainly via skin contact followed by ingestion and inhalation. Hazard quotient (HQ) values were < 1 except for Mn through dermal contact at all sites during partial and complete lockdown, similar to hazard index (HI), while Cr further showed high non-carcinogenic risks to children. Generally, children HI values were about 5–6 times higher than those of adults, suggesting a greater vulnerability of children to the health concerns caused by toxic elements in street dust. Carcinogenic risk (CR) values via ingestion pathway indicated all elements (except Pb) had significant health effect, while CR value by inhalation results showed no significant health effect. Cumulative carcinogenic risk (CCR) value had significant health effect except Pb in all land use categories. CCR values decreased during CL and reached at acceptable limit for most of the cases. This research provides a message to the local governments and environmental authorities to have a complete assessment of toxic elements in the street dust of Dhaka megacity in order to assuring public health safety and ecological sustainability.

    Abstract Background: Immune checkpoint inhibitors were used for patients with advanced non-small cell lung cancer (NSCLC) more and more frequently and the effects were thrilling. Toripalimab as a new immune checkpoint inhibitor has been shown to be effective in patients with advanced NSCLC. However, data regarding the safety and feasibility of surgical resection after treatment with toripalimab for NSCLC remain scarce. Here, we present a case with locally advanced NSCLC that received video-assisted thoracic surgery (VATS) lobectomy after treatment with toripalimab in combination with chemotherapy.
    Case presentation: A 62-year-old male patient with a history of coronary artery stenting operation for two times was found a 3.4 × 3.2 cm cavity mass in the upper lobe of the left lung and enlarged left hilar and mediastinal lymph nodes. Pathological results identified squamous cell carcinoma. The patient was diagnosed with a locally advanced NSCLC and received VATS left upper lobectomy and lymph node dissection after neoadjuvant chemotherapy plus toripalimab for 3 cycles. The postoperative pathological results showed complete tumor remission. Short-term follow-up results were excellent, and long-term results remain to be revealed.
    Conclusions: Our preliminary results showed that the use of neoadjuvant toripalimab and chemotherapy for the locally advanced NSCLC before surgical resection is safe and feasible.

    Abstract Purpose: To evaluate preoperative anxiety and postoperative quality of life in patients with periodontal mucogingival surgery, and provide a theoretical basis for preventing preoperative anxiety and improving postoperative quality of life in mucogingival surgery.
    Methods: According to the inclusion and exclusion criteria, 26 patients with mucogingival surgery were randomly selected, including 13 cases undergoing free gingival graft and 13 cases undergoing subepithelial connective tissue graft. All patients were asked to answer the following questionnaires which included self-rating anxiety scale (SAS), modified dental anxiety scale (MDAS), pain evaluation using visual pain scale (VAS), clinical performance evaluation (swelling, bleeding, nausea, oral odor), and oral function evaluation (chewing, speaking, sleeping, working). Data analysis was performed using SPSS 18.0 software package.
    Results: The preoperative SAS score was 44.33±11.99, 4 patients had anxiety, accounting for 15.38%. The preoperative MDSA score was 9.85±2.41, 4 patients had anxiety, accounting for 15.38%. The VAS values at 1 day, 3 days, 5 days, 7 days, and 10 days after surgery were moderate pain (4.54±1.32), mild pain (3.31±1.31), mild pain (2.00±1.14), and painless( 0.70±0.72), painless (0.08±0.27). The VAS values at 1 day, 3 days, and 5 days after FGG were greater than those after CTG (P<0.05).The most common discomforts after mucogingival surgery were swelling, bleeding, disturbance in chewing and speech. Swelling, disturbance in chewing and speech persisted until 7 days after surgery, and bleeding continued until 5 days after surgery. The postoperative discomfort of FGG was significantly higher than that of CTG.
    Conclusions: Four had preoperative anxiety prior to mucogingival surgery. The main clinical symptoms after surgery were moderate to mild pain, swelling, bleeding, disturbance in chewing and speech within 1-7 days after surgery. The effect of CTG on the quality of life of patients was significantly less than that of FGG.
