Fe-doped Cu-based bimetallic metal-organic frameworks as nanoscale microwave sensitizers for enhancing microwave thermal and dynamic therapy for hepatocellular carcinoma.

Microwave ablation (MWA) is recognized as a novel treatment modality that can kill tumor cells by heating the ions and polar molecules in these cells through high-speed rotation and friction. However, the size and location of the tumor affect the effective ablation range of microwave hyperthermia, resulting in residual tumor tissue and a high recurrence rate. Due to their tunable porous structure and high specific surface area, metal-organic frameworks (MOFs) can serve as microwave sensitizers, promoting microwave energy conversion owing to ion collisions in the porous structure of the MOFs. Moreover, iron-based compounds are known to possess peroxidase-like catalytic activity. Therefore, Fe-doped Cu bimetallic MOFs (FCMs) were prepared through a hydrothermal process. These FCM nanoparticles not only increased the efficiency of microwave-thermal energy conversion as microwave sensitizers but also promoted the generation of reactive oxygen species (ROS) by consuming glutathione (GSH) and promoted the Fenton reaction to enhance microwave dynamic therapy (MDT). The in vitro and in vivo results showed that the combination of MWA and MDT treatment effectively destroyed tumor tissues via microwave irradiation without inducing significant side effects on normal tissues. This study provides a new approach for the combined application of MOFs and microwave ablation, demonstrating excellent potential for future applications.

Transversus Thoracic Muscle Plane Block For Postoperative Pain in Pediatric Cardiac Surgery: A Systematic Review And Meta-Analysis of Randomized And Observational Studies.

OBJECTIVES: Pediatric patients undergoing cardiac surgery usually experience significant surgical pain. Additionally, the effect of poor surgical analgesia creates a pain continuum that extends to the postoperative period. Transversus thoracic muscle plane block (TTMPB) is a novel plane block technique that can provide analgesia to the anterior chest wall. The analgesic role of TTMPB in pediatric cardiac surgery is still uncertain. A meta-analysis was conducted to determine the analgesic efficacy of this procedure. DESIGN AND SETTING: Systematic review and meta-analysis. PubMed, Embase, Web of Science, CENTRAL, WanFang Data, and the China National Knowledge Infrastructure were searched to November 2023, and the Grading of Recommendations Assessment, Development, and Evaluation approach was followed to evaluate the certainty of evidence. PARTICIPANTS: Eligible studies enrolled pediatric patients from 2 months to 12 years old scheduled to undergo cardiac surgery, and randomized them to receive a TTMPB or no block/sham block. MEASUREMENTS AND MAIN RESULTS: Six studies that enrolled 601 pediatric patients were included. Low-certainty evidence from randomized trials showed that, compared with no block or sham block, TTMPB in pediatric patients undergoing cardiac surgery may reduce postoperative modified objective pain score at 12 hours (weighted mean difference [WMD] -2.20, 95% CI -2.73 to -1.68) and 24 hours (WMD -1.76, 95% CI -2.09 to -1.42), intraoperative opioid consumption (WMD -3.83, 95% CI -5.90 to -1.76 µg/kg), postoperative opioid consumption (WMD -2.51, 95% CI -2.84 to -2.18 µg/kg), length of intensive care unit (ICU) stay (WMD -5.56, 95% CI -8.30 to -2.83 hours), and extubation time (WMD -2.13, 95% CI -4.21 to -0.05 hours). Retrospective studies provided very low certainty that the results were consistent with the randomized trials. CONCLUSION: Very low- to low-certainty evidence showed that TTMPB in pediatric patients undergoing cardiac surgery may reduce postoperative pain, opioid consumption, ICU length of stay, and extubation time.

Clinical practice guidelines for prevention and treatment of postoperative gastrointestinal disorder with Integrated Traditional Chinese and Western Medicine (2023).

Postoperative gastrointestinal disorder (POGD) was a common complication after surgery under anesthesia. Strategies in combination with Traditional Chinese Medicine and Western medicine showed some distinct effects but standardized clinical practice guidelines were not available. Thus, a multidisciplinary expert team from various professional bodies including the Perioperative and Anesthesia Professional Committees of the Chinese Association of Integrative Medicine (CAIM), jointly with Gansu Province Clinical Research Center of Integrative Anesthesiology/Anesthesia and Pain Medical Center of Gansu Provincial Hospital of Traditional Chinese Medicine and WHO Collaborating Center for Guideline Implementation and Knowledge Translation/Chinese Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) Center/Gansu Provincial Center for Medical Guideline Industry Technology/Evidence-based Medicine Center of Lanzhou University, was established to develop evidence-based guidelines. Clinical questions (7 background and 12 clinical questions) were identified through literature reviews and expert consensus meetings. Based on systematic reviews/meta-analyses, evidence quality was analyzed and the advantages and disadvantages of interventional measures were weighed with input from patients' preferences. Finally, 20 recommendations were developed through the Delphi-based consensus meetings. These recommendations included disease definitions, etiologies, pathogenesis, syndrome differentiation, diagnosis, and perioperative prevention and treatment.

[Changes in Soil Nitrogen Components and Their Relationship with Environmental Factors with Different Tea Plantation Ages].

Changes in soil nitrogen components in tea gardens affect the soil nitrogen supply capacity and nitrogen cycle. In this study, soil samples were collected from forest land, cultivated land, and tea gardens with different plantation ages (30, 50, and 70 years) to explore the changes in soil nitrogen components and their relationship with physicochemical properties and enzyme activities. The results showed that:① with the increase in tea plantation age, the silt, total phosphorus, and urease and catalase activities gradually increased, whereas the sand, clay, pH, electrical conductivity, soil organic carbon, and the activities of invertase gradually decreased. The alkaline phosphatase activity increased first and then decreased with the increase in tea plantation age, and no significant differences were observed in soil water content and acid phosphatase activity. ② With the increase in tea plantation age, the contents of acid ammonia nitrogen, amino acid nitrogen, and nitrate nitrogen (NO3--N) increased significantly, and the contents of total nitrogen, acid ammonia nitrogen, hydrolyzable unknown nitrogen, and non-hydrolyzable nitrogen in tea gardens were significantly higher than those in forest land. ③ The total phosphorus, alkaline phosphatase, and urease were the main factors affecting soil nitrogen components. Among them, organic nitrogen components were significantly correlated with total phosphorus and alkaline phosphatase, and inorganic nitrogen components were significantly correlated with alkaline phosphatase, whereas total nitrogen had significant correlations with sand, silt, total phosphorus, urease, and alkaline phosphatase.

Catalpol attenuates osteoporosis in ovariectomized rats through promoting osteoclast apoptosis via the Sirt6-ERα-FasL axis.

BACKGROUND: Catalpol, a major active component of the Chinese herb Rehmannia glutinosa, possesses various pharmacological benefits, including anti-inflammatory, antidiabetic, and antitumor properties. Recent studies have reported that catalpol can attenuate bone loss and enhance bone formation. Nevertheless, the molecular mechanisms underlying its effects on osteoporosis pathogenesis remain unclear. PURPOSE: We investigated whether catalpol had a protective effect against postmenopausal osteoporosis (PMOP) and explored its exact mechanism of action. METHODS: Seventy-two rats were randomly divided into six groups: sham, model, low-dose catalpol (5 mg/kg/day), medium-dose catalpol (10 mg/kg/day), high-dose catalpol (20 mg/kg/day), and positive control (alendronate, 2.5 mg/kg). In this experiment, a ovariectomy was performed to establish a female rat model of PMOP. After 12 weeks of gavage, micro-computed tomography (micro-CT) and histochemical staining were performed to evaluate bone mass, bone microstructure and histological parameters. Furthermore, RAW 264.7 cells were induced by RANKL to form mature osteoclasts to investigate the effect of catalpol on osteoclast differentiation and apoptosis in vitro. Additionally, the osteoclast apoptosis-related proteins of Sirt6, ERα, FasL, NFATc1, cleaved-caspase 8, cleaved-caspase 3, and Bax were assessed using western blotting. The expressions of NFATc1, Ctsk, Oscar, and Trap were quantified using RT-qPCR. The apoptotic rate of the osteoclasts was determined using flow cytometry. Sirt6 knockdown was performed using siRNA gene silencing in experiments to investigate its role in catalpol-mediated osteoclast apoptosis. The deacetylation of ERα in osteoclasts was tested via co-immunoprecipitation. RESULTS: Catalpol (10 and 20 mg/kg) and alendronate (2.5 mg/kg) could significantly improve bone mineral density (BMD) and microstructure and decrease osteoclast density in ovariectomized (OVX) rats. In addition, catalpol (10 and 20 mg/kg) upregulated the expression of Sirt6, ERα, FasL, cleaved-caspase 8, cleaved-caspase 3, Bax, and downregulated the expression of NFATc1, Ctsk, Oscar, Trap both in vivo and in vitro. Catalpol also promoted ERα deacetylation and stabilized ERα protein to enhance the expression of FasL. In addition, Sirt6 knockdown by siRNA prevented ERα deacetylation and eliminated catalpol-mediated osteoclast apoptosis. CONCLUSIONS: The present study demonstrated that catalpol prevents estrogen deficiency-induced osteoporosis by promoting osteoclast apoptosis via the Sirt6-ERα-FasL axis. These findings revealed a novel molecular mechanism underpinning the impact of catalpol in the progression of osteoporosis and provided novel insights into the treatment of osteoporosis.

Vibrio methylphosphonaticus sp. nov., a methylphosphonate-decomposing bacterium isolated from surface seawater in the Xisha Islands, PR China.

A Gram-stain-negative, facultative anaerobic, methylphosphonate-decomposing, motile by a polar flagellum and rod-shaped marine bacterium, designated S4B1T, was isolated from the surface seawater collected from the Yongle Atoll (Xisha Islands, PR China). The pairwise alignment showed the highest sequence similarity of 97.5 and 96.6 % to Vibrio aestuarianus subsp. cardii 12_122_3T3T and Vibrio atypicus HHS02T, respectively. Phylogenetic analysis based on 16S rRNA gene and the phylogenomic analysis of single-copy genes showed that strain S4B1T belonged to the genus Vibrio and formed a close branch with Vibrio qingdaonensis ZSDZ65T. Growth of strain S4B1T occurred at 4-30 °C (optimum, 28 °C), at pH 6.0-8.0 (optimum, pH 7.0) and in the presence of 2-7 % (w/v) NaCl (optimum, 3 %). The predominant fatty acids (>10 %) were C16 : 0, iso-C16 : 0 and summed feature 3 (C16 : 1 ω7c or/and C16 : 1 ω6c). The DNA G+C content of the assembled genomic sequence was 44.3 mol%. Average nucleotide identity (ANI) values between S4B1T and its reference species were lower than the threshold for species delineation (95-96 %), in which its highest ANI value with V. qingdaonensis ZSDZ65T was 87.0 %. In silico DNA-DNA hybridization further showed that strain S4B1T had less than 70 % similarity to its relatives. On the basis of the polyphasic evidence, strain S4B1T is proposed to represent a novel species of the genus Vibrio, for which the name Vibrio methylphosphonaticus sp. nov. is proposed. The type strain is S4B1T (=KCTC 92311T=MCCC 1K06168T).

Effects of respiratory flora regulation on microbial environment and IL-10/STAT3 signaling pathway in the bronchiolitis obliterans after lung transplantation.

Our purpose of this study was to explore the application effect of respiratory flora regulation in bronchiolitis obliterans after lung transplantation, and its regulatory effect on the microbial environment of the lesion and the IL-10/STAT3 signaling pathway. 25 clean-grade C57BL/6 male mice and 5 BALB/c male mice were selected for orthotopic tracheal transplantation and postoperative respiratory flora regulation in a hospital animal room from Jan 2019 to Dec 2021. Next, the changes in the microbial environment and the IL-10/STAT3 signaling pathway before and after respiratory flora regulation were compared, so as to evaluate the regulatory effect of this method. The Simpson index did not show a significant difference before and after respiratory flora regulation intervention (P>0.05). However, the Chao1, ACE, Shannon, and Actinobacteria dominant indices were higher after the intervention. There were significant changes in the abundance of Proteobacteria, Bacteroidetes, Acidobacteria, Firmicutes, Propionibacterium, Corynebacterium, Staphylococcus, and Streptococcus after the intervention (P<0.05). Additionally, IL-10 and STAT3 levels were higher after the intervention and showed significant differences (P<0.05) compared to before. Regulating the respiratory tract flora can improve the microbial environment of bronchiolitis obliterans post-lung transplantation. This helps balance the respiratory flora, increase IL-10 and STAT3 levels, and aid in the recovery of inflammatory responses.

Association of Epstein-Barr virus (EBV) with lung cancer: meta-analysis.

Objective: Epstein-Barr virus (EBV) is a virus that is ubiquitous in humans. To investigate the association between EBV infection and lung cancer risk to reveal whether it is involved in the development and development of lung cancer. Although there has been discussion of EBV and lung cancer in the past. Through this study, we hope to deepen our understanding of the causes of lung cancer and provide new clues and targets for the prevention, early diagnosis and treatment of lung cancer. This study is also beneficial to the development of medical science and public health. First of all, the research results are expected to be incorporated into lung cancer prevention and treatment strategies and policies, so as to provide better treatment decisions for lung cancer patients and improve the survival rate and quality of life of patients. At the same time, communicating the research results to the public can help raise awareness of lung cancer risk factors. By encouraging healthy lifestyles and screening measures, the public can reduce their risk of lung cancer. In addition, this study also provides an important foundation for subsequent academic research and scientific exploration. It provides valuable information and inspiration for in-depth understanding of lung cancer and other related fields. Overall, this study makes an important contribution to both medical science and public health. Method: By September 26, 2022, an online database was used to conduct a literature search in English. Random effects models were employed to estimate the prevalence of EBV with 95% confidence intervals (CIs). Additionally, the pooled odds ratio (OR) and 95%CI were calculated from case-control studies to determine the association between EBV and lung cancer. Results: In this study of 886 patients with lung cancer, the overall prevalence of EBV infection was found to be 44.36% (95%CI: 4.08-16.9). Fourteen studies were included in the analysis, all of which used a case-control design and involved comparisons of tumors with adjacent or non-adjacent normal and non-cancerous controls. There was a significant difference in the prevalence of EBV infection in lung cancer tissues between China and other regions, with an odds ratio (OR) of 9.36 (95% confidence interval: 4.00-21.94, P<0.001, I²=73.5%). This suggests that the association between EBV infection and lung cancer cases is stronger in China than in other regions. Additionally, the prevalence of EBV infection varied across different pathological types of lung cancer, with rates of 81.08% for pulmonary lymphoepithelioma-like carcinoma (LELC),this a rare subtype of non-small cell lung cancer (NSCLC).34.78% for non-small cell lung cancer, and 21.17% for small cell lung cancer. The statistical analysis indicated that EBV infection was most significantly associated with cancer risk in LELC, while non-small cell lung cancer was more strongly associated with EBV than small cell lung cancer. Conclusion: The study found that EBV infection increases the risk of lung cancer by more than four times, and this risk is associated with the pathological type, lymphatic infiltration, and degree of differentiation of the lung cancer, particularly in the rare subtype of pulmonary lymphoepithelioma in non-small cell lung cancer(NSCLC). Additionally, there are racial and regional differences in the correlation between EBV-infected lung cancer, with the Asian population showing greater susceptibility. The study used normal or abnormal tissue adjacent to the tumor as a control, which is considered a more accurate method for determining the relationship between EBV infection and lung cancer.

[Effects of Supplementation of Different Amendments on Soil Heavy Metals and Enzyme Activities in Coastal Saline Land].

The supplementation of soil amendments may not only improve the soil physical and chemical properties but also lead to the accumulation of heavy metals in soil. This experiment included six treatments:control (CK), organic manure (OM), polyacrylamide+organic manure (PAM+OM), straw mulching+organic manure (SM+OM), buried straw+organic manure (BS+OM), and bio-organic manure+organic manure (BM+OM) to explore the effects of different soil amendments on heavy metals and soil enzyme activities in coastal saline land and the relationship between them. The results revealed that compared with that in the CK treatment, the contents of soil Cr, Cu, Ni, and Pb exhibited an upward trend after the supplementation of soil amendments, among which the SM+OM and PAM+OM treatments had the most significant effects on the contents of soil Cr and Cu, respectively, whereas the BM+OM treatment had the most significant effects on the contents of soil Ni and Pb. Compared with those in the CK treatment, the activities of soil invertase and urease increased significantly following supplementation of soil amendments, and the BM+OM treatment had the best effect. The alkaline phosphatase activity exhibited a slightly upward trend after the supplementation of soil amendments, whereas the catalase activity did not change significantly. The redundancy analysis revealed that the first two axes cumulatively accounted for 70.3% of the variability in enzyme activities, and the importance of single soil heavy metals on soil enzyme activity was as follows:Ni>Cu>Cr>Pb.

Interpretable XGBoost-SHAP Model Predicts Nanoparticles Delivery Efficiency Based on Tumor Genomic Mutations and Nanoparticle Properties.

Understanding the complex interaction between nanoparticles (NPs) and tumors in vivo and how it dominates the delivery efficiency of NPs is critical for the translation of nanomedicine. Herein, we proposed an interpretable XGBoost-SHAP model by integrating the information on NPs physicochemical properties and tumor genomic profile to predict the delivery efficiency. The correlation coefficients were 0.66, 0.75, and 0.54 for the prediction of maximum delivery efficiency, delivery efficiency at 24 and 168 h postinjection for test sets. The analysis of the feature importance revealed that the tumor genomic mutations and their interaction with NPs properties played important roles in the delivery of NPs. The biological pathways of the NP-delivery-related genes were further explored through gene ontology enrichment analysis. Our work provides a pipeline to predict and explain the delivery efficiency of NPs to heterogeneous tumors and highlights the power of simultaneously using omics data and interpretable machine learning algorithms for discovering interactions between NPs and individual tumors, which is important for the development of personalized precision nanomedicine.

Investigating Links between Moderate-to-Vigorous Physical Activity and Self-Rated Health Status in Adolescents: The Mediating Roles of Emotional Intelligence and Psychosocial Stress.

Adolescence represents a crucial phase, characterized by rapid physical and mental development and numerous challenges. Physical activity plays a vital role in the mental well-being of adolescents; however, due to the prevailing educational philosophy prioritizing academic performance, adolescent participation in physical activities has yet to reach its full potential. Thus, this study aims to investigate the effects of moderate-to-vigorous physical activity on adolescents' emotional intelligence, psychosocial stress, and self-rated health status. To achieve this objective, a cluster sampling method was employed to collect data from 600 adolescents in 10 schools across five municipal districts of Changsha, China. A total of 426 valid questionnaires were returned and analyzed. Utilizing AMOS v.23, a structural equation model was constructed to validate the hypotheses. The findings reveal that moderate-to-vigorous physical activity significantly impacts adolescents' emotional intelligence and self-rated health status. Conversely, it exerts a significant negative influence on their psychosocial stress. Moreover, emotional intelligence and psychosocial stress mediate the relationship between moderate-to-vigorous physical activity and self-rated health status. In light of these results, education departments, schools, and families must embrace a paradigm shift in educational philosophies and provide robust support for adolescents to engage in moderate-to-vigorous physical activities.

Theranostic mesoporous platinum nanoplatform delivers halofuginone to remodel extracellular matrix of breast cancer without systematic toxicity.

The enriched collagens in the extracellular matrix (ECM) of breast cancer substantially impede drug delivery. Halofuginone (HF), a potent antifibrotic agent, was effective to deplete the collagens and remodel the ECM by inhibiting the TGFß pathway. However, the application of HF was hindered by its strong liver toxicity. Herein, mesoporous platinum (mPt) nanoparticles were constructed to load HF as theranostic nanoplatforms. mPt had a uniform spherical structure with a diameter of 79.83 ± 6.97 nm and an average pore diameter of 20 nm and exhibited good photothermal conversion efficiency of 62.4%. The obtained HF-loaded nanoplatform (PEG@mPt-HF) showed enhanced cytotoxicity through the combination of photothermal therapy and the anti-TGFß effect induced by HF. The animal imaging and histochemical assays confirmed the PEG@mPt-HF could efficiently deliver HF to tumors (monitored by CT) and remodel the ECM by TGFß pathway inhibition, which resulted in increased anti-cancer efficacy. Importantly, the liver toxicity observed in HF-treated mice was negligible in those treated by PEG@mPt-HF. Overall, this study designed a theranostic nanoplatform to remodel the ECM with remarkably reduced systematic toxicity and enhance the therapeutic efficacy through combination treatment.

Nonlinear dynamics of EEG responses to unmanned vehicle visual detection with different levels of task difficulty.

The main objective of this study was to examine the presence of chaos in the EEG recordings of brain activity under simulated unmanned ground vehicle visual detection scenarios with different levels of task difficulty. One hundred and fifty people participated in the experiment and completed four visual detection task scenarios: (1) change detection, (2) a threat detection task, (3) a dual-task with different change detection task rates, and (4) a dual-task with different threat detection task rates. We used the largest Lyapunov exponent and correlation dimension of the EEG data and performed 0-1 tests on the EEG data. The results revealed a change in the level of nonlinearity in the EEG data corresponding to different levels of cognitive task difficulty. The differences in EEG nonlinearity measures among the studied levels of task difficulty, as well as between a single task scenario and a dual-task scenario, have also been assessed. The results increase our understanding of the nature of unmanned systems' operational requirements.

[Effects of transcutaneous electrical acupoint stimulation at different times assisted general anesthesia on stress response of patients undergoing open posterior lumbar surgery].

OBJECTIVE: To observe the effects of transcutaneous electrical acupoint stimulation (TEAS) at different times on the stress response during anesthesia and operation in the patients undergoing open posterior lumbar surgery. METHODS: A total of 94 patients undergoing open posterior lumbar surgery were randomly assigned to preoperative TEAS group(32 cases), intraoperative TEAS group(31 cases) and sham-TEAS group(31 cases). The same anesthetic method was used in the patients of 3 groups. Four electrodes were attached to the bilateral Hegu (LI4) and Neiguan (PC6) and connected to the electronic acupuncture instrument when patients entered the operation room. In the preoperative TEAS group, the patients received TEAS (10 to 20 mA) for 30 min before the anesthetic induction. TEAS (15 mA) was provided immediately when the operation starts till the end of ope-ration for the patients of the intraoperative TEAS group. In the sham-TEAS group, the electronic acupuncture instrument was switched on during the whole procedure of operation, but no electric current was output. Separately, at the moment of entering the operation room (T0), before endotracheal intubation (T1), at the time of endotracheal intubation (T2), 10 min after skin resection (T3), at the end of surgery (T4), recovery from anesthesia (T5) and at the time of extubation (T6), the heart rate (HR) and mean arterial pressure (MAP) were recorded. Using ELISA, the concentrations of epinephrine (E), norepinephrine (NE), dopamine (DA), cortisol (Cor) in serum were assayed at T0, T3, and T4; and blood glucose was tested with blood sugar paper at the same time points. RESULTS: Compared with T0 of the same group, HR was increased at T2 and decreased at T3 of the patients in the sham-TEAS group and the intraoperative TEAS group (P<0.05). Compared with the sham-TEAS group at the same time points, HR was decreased at T2 and increased at T3 of the patients in the preoperative TEAS group (P<0.05), and it was decreased at T6 of patients in the intraoperation TEAS group (P<0.05). HR was reduced at T2 in the preoperative TEAS group when compared with the intraoperative TEAS group. Compared with T0 of the same group, MAP was elevated at T2 and reduced at T3 and T4 in the sham-TEAS group (P<0.05); it decreased at T3, T4 and T5 in the preoperative TEAS group (P<0.05); it rose at T2 and was reduced at T3, T4 and T5 in the intraoperative TEAS group (P<0.05). When compared with the sham-TEAS group at the same time points, MAP decreased at T2 in the preoperative TEAS group (P<0.05), and at T6 in the intraoperative TEAS group (P<0.05). MAP was reduced at T2 and elevated at T6 in the preoperative TEAS group in comparison with the intraoperative TEAS group (P<0.05) at the same time points. Compared with T0 of the same group, the contents of E was increased at T3 in the sham-TEAS group and the intraoperative TEAS group (P<0.05); it was increased in all of the three groups at T4 (P<0.05); the contents of NE, DA, Cor and the blood glucose were increased at T4 in the sham-TEAS group (P<0.05). Compared with the sham-TEAS group at the same time points, the contents of E, DA at T3 and T4 and Cor at T3 in serum of the preoperative TEAS group were decreased (P<0.05); and the contents of E, NE, DA and Cor at T4 in the intraoperative TEAS group were decreased (P<0.05). CONCLUSION: TEAS-assisted general anesthesia can better maintain the stability of HR and MAP during anesthesia and operation in patients undergoing open posterior lumbar surgery, and reduce surgical stress response.

Tumor-targeting semiconducting polymer nanoparticles: efficient adjuvant photothermal therapy using ultra-low laser power inhibits recurrences after breast-conserving surgery.

The need for adjuvant therapy to inhibit local recurrence after breast-conserving surgery with minimal side effects is great. Adjuvant photothermal therapy (aPTT) has the potential to replace radiotherapy and eliminates its inherent damage to healthy tissues. Herein, we functionalized semiconducting polymer nanoparticles (SPNs) with cRGD-peptide and silicon 2,3-naphthalocyanine bis(trihexylsilyloxide) (NIR775) to target breast cancer and perform aPTT under an ultra-low laser power (0.2 W cm-2) after breast-conserving surgery (BCS). The synthesized RGD-SPNNIR775 showed an excellent photothermal conversion efficiency and biocompatibility and was demonstrated to accumulate in tumors specifically. The BCS could be performed with confidence under the guidance of preoperative and postoperative fluorescence imaging. Notably, the aPTT completely inhibited the local recurrence after the BCS without compromising the cosmetic effect of the BCS. These results indicate the prospect of RGD-SPNNIR775 as a theranostic nanoplatform for efficient aPTT using an ultra-low laser power to control recurrence after BCS.

The Complete Mitochondrial Genome of Homophyllia bowerbanki (Scleractinia, Lobophylliidae): The First Sequence for the Genus Homophyllia.

Reef-building coral species of the order Scleractinia play an important role in shallow tropical seas by providing an environmental base for the ecosystem. The molecular data of complete mitochondrial genome have become an important source for evaluating phylogenetic and evolutionary studies of Scleractinia. Here, the complete mitogenome of Homophyllia bowerbanki (Milne Edwards and Haime, 1857), collected from Nansha Islands of the South China Sea, was sequenced for the first time through a next-generation sequencing method. H. bowerbanki is the first species of its genus for which the mitogenome was sequenced. This mitogenome was 18,154 bp in size and included two transfer RNA genes (tRNAs), 13 protein-coding genes (PCGs), and two ribosomal RNA genes (rRNAs). It showed a similar gene structure and gene order to the other typical scleractinians. All 17 genes were encoded on the H strand and the total GC content was 33.86% in mitogenome. Phylogenetic analysis (maximum likelihood tree method) showed that H. bowerbanki belonged to the "Robust" clade and clustered together with other two species in the family Lobophylliidae based on 13 PCGs. The mitogenome can provide significant molecular information to clarify the evolutionary and phylogenetic relationships between stony corals and to facilitate their taxonomic classification; it can also support coral species monitoring and conservation efforts.

Vibrio sinus sp. nov., a marine bacterium isolated from coastal seawater.

A Gram-straining-negative, facultatively anaerobic, motile by means of a polar flagellum and rod-shaped marine bacterium, designated S4M6T, was isolated from surface seawater collected in Dongshan Bay (Fujian, PR China). Phylogenetic analysis based on 16S rRNA genes, phylogenomic analysis of single-copy gene families and whole genome data indicated that S4M6T represented a member of the genus Vibrio. The closest phylogenetic relatives of S4M6T were Vibrio marisflavi CGMCC 1.8994T (97.8 % 16S rRNA gene sequence pairwise similarity), Vibrio variabilis LMG 25438T (96.9 %), Vibrio gangliei SZDIS-1T (96.2 %) and Vibrio aestivus M22T (96.1 %). The growth of S4M6T occurred at 15-35 °C (optimum 28 °C), pH 4.0-9.0 (optimum 5.0-7.0) and in the presence of 2-5 % (w/v) NaCl (optimum 3 %). The predominant fatty acids (>10 %) are C16 : 0, summed feature 3 (C16 : 1ω7c and/or C16 :  1ω6c) and summed feature 8 (C18 : 1ω7c and/or C18 :  1ω6c). The DNA G+C content of the assembled genomic sequences was 43.4 % for S4M6T. Average nucleotide identity (ANI) values between S4M6T and the reference species were lower than the threshold for species delineation (95-96 %); in silico DNA-DNA hybridization further indicated that S4M6T had less than 70 % similarity to its relatives. On the basis of the polyphasic evidence, strain S4M6T is proposed to represent a novel species of the genus Vibrio, for which the name Vibrio sinus sp. nov. is proposed. The type strain is S4M6T (= KCTC 92312T= MCCC 1K06167T).

Keep Moving to Retain the Healthy Self: The Influence of Physical Exercise in Health Anxiety among Chinese Menopausal Women.

Menopause is a period of high incidence of chronic diseases. Women experience various physical and psychological discomforts during menopause, and hormonal changes exacerbate mood swings in menopausal women and also cause them to begin to experience excessive worry and anxiety about their health problems. This study was a cross-sectional survey investigating the relationship between physical activity and women's health anxiety. Using cluster sampling, a valid sample of 455 females aged 45-50 was collected from 78 communities in five municipal districts in Changsha, China, and AMOS v.23 was adopted to construct a structural equation model to verify the hypotheses. The results indicate that interpersonal competence and emotional intelligence are negatively associated with health anxiety. Furthermore, interpersonal competence and emotional intelligence mediate the relationship between physical exercise and health anxiety, which means that menopausal women with more physical exercise, higher interpersonal competence, and higher emotional intelligence reported lower health anxiety. Finally, to alleviate menopausal women's health anxiety and reduce their risk of chronic diseases, the government, community, and family should create conditions and opportunities for women to participate in group physical activities.

Promoting Physical Activity among Working Women: The Influence of Perceived Policy Effectiveness and Health Awareness.

In recent years, patients with chronic diseases have shown a younger trend due to physical inactivity and irregular lifestyles. Accordingly, the Chinese government has implemented the "National Fitness Program", which aims to enhance people's health by popularizing exercise and a healthy lifestyle. However, women are less physically active than men, and how to appeal to women to devote themselves to fitness activities has become a social concern. Based on the expanded theory of planned behavior (TPB), this study explores the impact of the perceived policy effectiveness and health awareness on physical activity among working women. This study adopted a repeated cross-sectional study method, and each respondent was asked to complete a two-stage survey. The structural model of the extended TPB was tested using sample data from 376 working women in Changsha, China. The results show that perceived policy effectiveness and health awareness positively affect actual behavioral control and implementation intention. Among them, perceived policy effectiveness has the most significant impact on implementation intention, followed by health awareness. Furthermore, actual behavioral control and implementation intention mediate the relationship between perceived policy effectiveness/health awareness and physical activity. The findings suggest that to promote physical activity among working women, the Chinese government should deepen the implementation of the "National Fitness Program" and raise the public's health awareness.
