Abstract
BACKGROUND The effect of sodium-glucose cotransporter 2 (SGLT2) inhibitors on cancer has yet to be fully elucidated. OBJECTIVE This systematic review and meta-analysis investigated the effects of SGLT2 inhibitors on cancer. METHODS We searched the PubMed and ClinicalTrials.gov databases up to July 15, 2023, to identify eligible randomized, double-blind, placebo-controlled trials that lasted at least ≥24 weeks. The primary outcome was the overall cancer incidence, and the secondary outcomes were the incidences of various types of cancer. We used the Mantel-Haenszel method, fixed effects model, risk ratio (RR) and 95% confidence interval (CI) to analyze dichotomous variables. Subgroup analysis was performed based on the SGLT2 inhibitor type, baseline conditions, and follow-up duration. All meta-analyses were performed using RevMan5.4.1 and Stata MP 16.0. RESULTS A total of 58 publications (59 trials) were included, comprising 113,909 participants with type 2 diabetes mellitus and/or chronic kidney disease and/or high cardiovascular risk and/or heart failure (SGLT2 inhibitor group, 63864; placebo group, 50045). Compared to the placebo SGLT2 inhibitors did not significantly increase the overall incidence of cancer (RR 1.01; 95% CI 0.94-1.08; p = 0.82). However, ertugliflozin did significantly increase the overall incidence of cancer (RR 1.29; 95% CI 1.01-1.64; p = 0.04). SGLT2 inhibitors did not increase the risks of bladder or breast cancer. However, dapagliflozin did significantly reduce the risk of bladder cancer by 47% (RR 0.53; 95% CI 0.35-0.81; p = 0.003). SGLT2 inhibitors had no significant effect on the risks of gastrointestinal, thyroid, skin, respiratory, prostate, uterine/endometrial, hepatic and pancreatic cancers. Dapagliflozin reduced the risk of respiratory cancer by 26% (RR 0.74; 95% CI 0.55-1.00; p = 0.05). SGLT2 inhibitors (particularly mediated by dapagliflozin and ertugliflozin but not statistically significant) were associated with a greater risk of renal cancer than the placebo (RR 1.39; 95% CI 1.04-1.87; p = 0.03). CONCLUSION SGLT2 inhibitors did not significantly increase the overall risk of cancer or the risks of bladder and breast cancers. However, the higher risk of renal cancer associated with SGLT2 inhibitors warrants concern.

Abstract
Background and purpose This study aimed to explore the correlation and causal relationship between fibrinogen, D-dimer, and the severity of cerebral white matter hyperintensity (MMH). Methods A retrospective analysis of 120 patients with cerebral small vessel disease (CSVD) confirmed by head MRI attending the Third Affiliated Hospital of Beijing University of Traditional Chinese Medicine from August 2021 to February 2023 was performed. According to the Fazekas scale score, the patients were divided into 42 cases in the mild group, 44 cases in the moderate group, and 34 cases in the severe group. The levels of fibrinogen and D-dimer were compared among the three groups; the correlations between fibrinogen, D-dimer, and WMH severity were further analyzed; and independent risk factors for WMH severity were explored using the multivariate ordered logistic regression analysis. Furthermore, a two-sample Mendelian randomization (MR) analysis was performed to investigate the genetically predicted effect of fibrinogen and D-dimer on WMH. Results As the severity of WMH increased, the levels of D-dimer and fibrinogen also gradually increased, and the results showed a positive correlational association, with significant differences within the groups (all p < 0.05); the multivariate ordered logistic regression model showed that after adjusting for the relevant covariates, D-dimer (OR = 5.998, 95% CI 2.213-16.252, p < 0.001) and fibrinogen (OR = 9.074, 95% CI 4.054-20.311, p < 0.001) remained independent risk factors for the severity of WMH. In the MR study, the random-effect inverse variance weighted (IVW) model showed that increased levels of genetically predicted D-dimer (OR, 1.01; 95% confidence interval 0.95-1.06; p = 0.81) and fibrinogen (OR, 1.91; 95% confidence interval 0.97-3.78; p = 0.06) were not associated with increased risk of WMH. The authors did not obtain strong evidence of a direct causal relationship between D-dimer, fibrinogen, and WMH. Conclusion In this retrospective-based study, the authors found possible associations between D-dimer, fibrinogen, and WMH, but there was no obvious causal evidence. Further efforts are still needed to investigate the pathophysiology between D-dimer, fibrinogen, and WMH.

Abstract
Land-ocean interactions greatly impact the evolution of coastal life on earth. However, the ancient geological forces and genetic mechanisms that shaped evolutionary adaptations and allowed microorganisms to inhabit coastal brackish waters remain largely unexplored. In this study, we infer the evolutionary trajectory of the ubiquitous heterotrophic archaea Poseidoniales (Marine Group II archaea) presently occurring across global aquatic habitats. Our results show that their brackish subgroups had a single origination, dated to over 600 million years ago, through the inversion of the magnesium transport gene corA that conferred osmotic-stress tolerance. The subsequent loss and gain of corA were followed by genome-wide adjustment, characterized by a general two-step mode of selection in microbial speciation. The coastal family of Poseidoniales showed a rapid increase in the evolutionary rate during and in the aftermath of the Cryogenian Snowball Earth (∼700 million years ago), possibly in response to the enhanced phosphorus supply and the rise of algae. Our study highlights the close interplay between genetic changes and ecosystem evolution that boosted microbial diversification in the Neoproterozoic continental margins, where the Cambrian explosion of animals soon followed.

Abstract
BACKGROUND Serum tumor markers have not yet been developed for the clinical diagnosis and treatment of sinonasal inverted papilloma (SNIP), one of the most significant sinonasal tumors. Therefore, this study aimed to determine the diagnostic value of serum squamous cell carcinoma antigen (SCCA) and cytokeratin fragment antigen 21-1 (CYFRA 21-1) for SNIP. METHODS Clinical data were obtained from 101, 56, and 116 patients with SNIP, sinonasal squamous cell carcinoma (SNSCC), and unilateral chronic rhinosinusitis (CRS), respectively. Preoperative serum SCCA and CYFRA 21-1 levels were compared, and logistic regression analyses were performed to screen serum tumor markers, which may be used to diagnose SNIP. Diagnostic cut-off values were determined using receiver operating characteristic (ROC) curves, and their diagnostic power was verified. RESULTS Serum SCCA and CYFRA 21-1 differentiated SNIP from CRS with the cut-off values of 1.97 ng/mL and 2.64 ng/mL and the areas under the ROC curves (AUC) of 0.895 and 0.766, respectively, and the AUC of the combination of the two markers was 0.909. CYFRA 21-1 differentiated SNIP with malignant transformation from that without malignant transformation with a cut-off value of 3.51 ng/mL and an AUC of 0.938. CYFRA 21-1 distinguished SNIP with malignant transformation from SNSCC with a cut-off value of 3.55 ng/mL and an AUC of 0.767. CONCLUSIONS This study provides novel potential diagnostic tools for SNIP by demonstrating the use of serum SCCA and CYFRA 21-1 in the diagnosis of SNIP.

Abstract
Ammonia-oxidizing archaea (AOA) are among the most ubiquitous and abundant archaea on Earth, widely distributed in marine, terrestrial, and geothermal ecosystems. However, the genomic diversity, biogeography, and evolutionary process of AOA populations in subsurface environments are vastly understudied compared to those in marine and soil systems. Here, we report a novel AOA order Candidatus (Ca.) Nitrosomirales which forms a sister lineage to the thermophilic Ca. Nitrosocaldales. Metagenomic and 16S rRNA gene-read mapping demonstrates the abundant presence of Nitrosomirales AOA in various groundwater environments and their widespread distribution across a range of geothermal, terrestrial, and marine habitats. Terrestrial Nitrosomirales AOA show the genetic capacity of using formate as a source of reductant and using nitrate as an alternative electron acceptor. Nitrosomirales AOA appear to have acquired key metabolic genes and operons from other mesophilic populations via horizontal gene transfer, including genes encoding urease, nitrite reductase, and V-type ATPase. The additional metabolic versatility conferred by acquired functions may have facilitated their radiation into a variety of subsurface, marine, and soil environments. We also provide evidence that each of the four AOA orders spans both marine and terrestrial habitats, which suggests a more complex evolutionary history for major AOA lineages than previously proposed. Together, these findings establish a robust phylogenomic framework of AOA and provide new insights into the ecology and adaptation of this globally abundant functional guild.

Abstract
Salmonella enterica serovar Enteritidis (S. Enteritidis) is a zoonotic pathogen that can infect both humans and animals. Among the 13 types of fimbrial operons in S. Enteritidis, the highly conserved Peg fimbriae play a crucial role in the adhesion and invasion of S. Enteritidis into host cells but are not well studied. In this study, we identified the ATP synthase subunit alpha (ATPase α) as a ligand of Peg fimbriae using ligand blotting and mass spectrometry techniques. We confirmed the in vitro binding of ATPase α to the purified adhesion protein (PegD). Furthermore, we used siRNA to suppress the expression of ATPase α gene Atp5a1 in Leghorn male hepatoma (LMH) cells, which resulted in a significant reduction in the adhesion rate of S. Enteritidis to the cells (P < 0.05). The findings in this study provide insight into the mechanism of S. Enteritidis infection through Peg fimbriae and highlight the importance of ATPase α in the adhesion process.RESEARCH HIGHLIGHTS Ligand blotting was performed to screen the ligand of S. Enteritidis Peg fimbriae.Binding assay confirmed that ATPase α is the ligand of the Peg fimbriae.siRNA targeting ATPase α gene (Atp5a1) significantly reduced S. Enteritidis adhesion.

Abstract
Bariatric surgery, as the most effective approach to treating obesity at present, encompasses a wide array of procedures. However, due to the significant anatomical changes to the gastrointestinal tract caused by most of these procedures, they are associated with certain risks of complications. In the pursuit of minimizing trauma, bariatric surgeons have begun exploring new surgeries in addition to traditional procedures. Gastric plication surgeries encompass various procedures such as gastric fundoplication, gastric greater curvature plication, endoscopic sleeve gastroplasty, combined gastric fundoplication with gastric greater curvature plication, and combined gastric fundoplication with sleeve gastrectomy, among others. The efficacy and risks of complications associated with these procedures fall between those of medical therapy and sleeve gastrectomy. Gastric fundoplication, functioning as an anti-reflux procedure, can also be integrated into weight loss surgical interventions to effectively address obesity-related gastroesophageal reflux disease in obese patients. Both gastric greater curvature plication and endoscopic sleeve gastroplasty yield favorable weight loss outcomes. Beyond the impact of folding procedures on body mass, gastric plication surgeries can also be combined with other techniques. The combination of gastric fundoplication with sleeve gastrectomy or greater curvature plication can reduce body mass and mitigate reflux, while the combination of greater curvature plication with gastric bypass and similar procedures can further enhance weight loss and metabolic improvements.

Abstract
Ethnic minority women experience disparities in mammography screening utilisation and breast cancer outcomes. This systematic review and meta-analysis synthesised multidomain and multilevel factors that intersect to influence the utilisation of mammography among ethnic minorities. A literature search was conducted in five databases (PubMed, Ovid MEDLINE, EMBASE, CINAHL, and PsycINFO) from inception to May 2022. Guided by the National Institute on Minority Health and Health Disparity research framework, the retrieved data were synthesised using narrative summaries and meta-analyses. Among the 27 studies, most (n = 24) reported individual, interpersonal, and community factors in the health care system domain. In the sociocultural domain, interpersonal and societal (n = 8) factors, such as modesty and karma beliefs, were less frequently identified than individual (n = 20) factors in relation to acculturation. Only individual-level factors were reported for the biological and physical/built environment (e.g., rural residence) domains. In the behavioural domain, cancer screening behaviours had a high combined prediction ability (odds ratio = 18.23; I2 = 23%), whereas interpersonal (e.g., family obligations) and community (e.g., neighbourhood violence) factors discouraged mammography screening. Special focus should be given to ethnic minority women, especially those living in rural areas, those with considerable family obligations, and those who have suffered from violence and other life pressures, to increase their access to mammography services. Multidomain and multilevel efforts, culturally appropriate strategies, and equity-advancing policies such as geographic access and insurance coverage would help to mitigate the ethnic disparities in mammography screening.

Abstract
PURPOSE The function of B cells in papillary thyroid cancer (PTC) is controversial. The role of B-cell-related tertiary lymphoid structures (TLSs) is still unclear. Whether B cells exert their anti-tumor effect through forming TLS in PTC needs further investigation. METHODS We detected the percentage of B cells in PTC tissues by multi-parameter flow cytometry. Paraffin-embedded tumor tissues of 125 PTC patients were collected and stained with Haematoxylin-Eosin (H&E) for inflammatory infiltration analysis in combination with clinical features. Multiplexed immunohistochemistry (mIHC) was performed to verify the TLSs in above inflammatory infiltration. Correlation of B cells and TLSs with prognosis was analyzed using the TCGA database. RESULTS We observed that PTC patients with higher expression of B lineage cell genes had improved survival and the percentage of B cells in the PTC tumor tissues was variable. Moreover, PTC tumor tissues with more B cells were surrounded by immune cell aggregates of varying sizes. We furtherly confirmed the immune cell aggregates as TLSs with different maturation stages. By analyzing PTC data from TCGA database, we found the maturation stages of TLSs were associated with genders and clinical stages among PTC patients. Moreover, patients with high TLSs survived longer and had a better prognosis. CONCLUSION B cells are associated with the existence of TLSs which have different maturation stages in PTC. Both B cells and TLSs are associated with the survival rate of PTC. These observations indicate that the anti-tumor effects of B cells in PTC are associated with TLSs formation.

Abstract
Objective: To study the effect and mechanism of post-ischemic treatment of nalmefene in alleviating the lung ischemia-reperfusion injury by inhibiting ferroptosis through activation of the Sirt 1/Nrf 2/HO-1 axis. Methods: A total of 60 rats were randomly divided into six groups equally (n=10): the sham group, the model group(I/R), the nalmefene group, the nalmefene+EX527 group, the nalmefene+ML385 group, the nalmefene+Fe-citrate group (nalmefene+Fe group). The sham group without drug treatment was not treated with ischemia-reperfusion. The pulmonary ischemia-reperfusion model was established by occlusion of the left pulmonary hilum in the model group without drug treatment. After ischemic treatment, the nalmefene group was injected with nalmefene (15 μg/kg) via the tail vein at 5 minutes before reperfusion. The nalmefene+EX527 group, the nalmefene+ML385 group, and the nalmefene+Fe group were injected intraperitoneally with EX527 (5 mg/kg), ML385 (30 mg/kg), Fe-citrate(15 mg/kg), respectively, 2 h before moulding and then injected with nalmefene (15 μg/kg) via the tail vein at 5 minutes before reperfusion. All rats were sacrificed three hours after reperfusion, and the specimens from the upper lobe of the left lung tissue were preserved. The degree of lung tissue injury and the wet/dry weight ratio were assessed in each group of rats. Fe 2+, MDA, TNF-α, and IL-6 content, GSH activity and the expression levels of Sirt1, Nrf2, HO-1, ACSL4 and GPX4 were determined. Results: Compared with the sham group, the wet/dry weight ratio, lung tissue injury score, ACSL 4 expression level, Fe 2+, TNF-α, IL-6 and MDA content, Sirt 1, Nrf 2, HO-1 messenger RNA and protein expression levels were significantly increased (P<0.01), while GPX 4 expression level and GSH activity were significantly decreased in the model group (P<0.01). Compared with the model group, wet/dry weight ratio, lung tissue injury score, ACSL 4 expression level, Fe 2+, TNF-α, IL-6, and MDA content decreased significantly (P<0.01), Nrf 2, HO-1 messenger RNA and protein, GPX 4 expression, and GSH activity were significantly increased in the nalmefene group and the nalmefene+EX527 group (P<0.01). Sirt 1 messenger RNA and protein expression increased significantly in the nalmefene (P<0.01) and the nalmefene+EX527 groups (P>0.05). In the nalmefene+ML385 group, the wet/dry weight ratio, lung tissue injury score, TNF-α and IL-6 content were decreased significantly (P<0.01), while Sirt 1 messenger RNA and protein expression levels were significantly increased (P<0.01), but there were no significant changes in Nrf 2, HO-1 messenger RNA and protein expression levels, ACSL 4 and GPX 4 expression levels, Fe 2+, MDA content, and GSH activity (P>0.05). In the nalmefene+Fe group, wet/dry weight ratio, lung-injury score, TNF-α, IL-6, MDA content were decreased significantly (P<0.01), messenger RNA and protein expression levels of Sirt 1, Nrf 2, HO-1, and GSH activity were increased significantly (P<0.01), but there were no significant changes in Fe 2+content, ACSL 4 and GPX 4 expression levels (P>0.05). Compared with the nalmefene group, in the nalmefene+EX527 group, the nalmefene+ML385 group and the nalmefene+Fe group, wet/dry weight ratio, lung tissue damage score, ACSL 4 expression level, TNF-α, IL-6 and MDA content were significantly increased (P<0.01), the expression level of GPX 4 and GSH activity were significantly decreased (P<0.01). The expression levels of Sirt 1, Nrf 2, HO-1 messenger RNA and protein were significantly decreased in the nalmefene+EX527 group (P<0.01). The expression levels of Nrf 2, HO-1 messenger RNA and protein decreased significantly in the namemefene+ML385 group (P<0.01), but there was no significant change in Sirt 1 messenger RNA and protein expression level (P>0.05). Sirt 1, Nrf 2, HO-1 messenger RNA-protein expression levels did not change significantly in the nalmefene+Fe group (P>0.05). Conclusion: Post-ischemic treatment with nalmefene hydrochloride may alleviate pulmonary ischemia-reperfusion injury by inhibiting ferroptosis through activation of the Sirt 1/Nrf 2/HO-1 axis.

Abstract
Objective: To investigate and analyze the allocation status of oral health resources in Yunnan Province at the end of the 13th Five-Year Plan, providing a scientific basis for the rational resource allocation and formulation regional oral health plan for government health administrative departments. Methods: With the method of general survey, a cross-sectional study was conducted to investigate the allocation of material and human resources of all kinds of stomatological medical institutions registered in the health administrative departments in Yunnan before January 1, 2020. The general situation of oral health resources was analyzed by descriptive statistical analysis. Results: There were 2 712 stomatological medical institutions in Yunnan, 634 public and 2 078 non-public included. The largest number was in Kunming (1 167) and the least in Diqing (19). There were 9 018 dental chairs in total, among which 2 584 in public and 6 434 in non-public. Kunming had the largest number of chairs (3 612) and Nujiang had the least (57). There were 702 oral and maxillofacial surgical beds, all of which were distributed in public. There were 15 148 stomatological personnel, including 3 667 in public and 11 481 in non-public. The average ratio of stomatologist to population was 1∶6 615. Dehong (1∶6 620) was close to this average level, while Kunming (1∶2 283) and Yuxi (1∶4 936) were lower than the average and the other 13 states (cities) were higher. The population ratio of licensed stomatologist was only 1∶9 110. The average ratio of stomatologist to nurses was 1∶0.94. Honghe (1∶1.05), Kunming (1∶1.00), Yuxi (1∶1.18) and Qujing (1∶0.94) was better than or reached the average level, while the other 13 states (cities) were lower than this average. And this ratio in public comprehensive medical institutions was only 1∶0.38. Conclusions: The distribution of oral health resources in Yunnan was unbalanced between public and non-public institutions and among states (cities), mainly distributed in economically developed states (cities) and non-public institutions. For the oral health in Yunnan Province, the workforce was insufficient and the structure was unreasonable, and the proportion of nurses was seriously insufficient in public comprehensive medical institutions.

Abstract
PURPOSE/OBJECTIVE(S) This study investigates the feasibility of using Xsight Diaphragm Tracking (XDT) for liver tumors located near or in the diaphragm during CyberKnife Synchrony Treatment. MATERIALS/METHODS Eight patients (46 fractions) with liver tumors located near or in the diaphragm were reviewed retrospectively. Prior to motion data analysis, baselines were flattened to remove the portions with significant changes and improve accuracy. To reduce the uncertainty about sudden irregular breathing, respiratory data were calculated as a rolling average. The overall tracking accuracy based on the patient-specific respiratory curve was evaluated using E2E testing with CIRS (18023-A) dynamic phantom. RESULTS Three main trajectories were observed in this work: Linearity (1/8), Linear radial type (6/8) and Hysteresis (1/1). The mean amplitude was 8.56±4.54 mm, 2.77±2.83 mm, and 4.23±3.92 mm for S-I, L-R, and A-P components. The linear trajectory patient had a more concentrated amplitude distribution. The baseline shifts were 5.88 mm (S-I), 2.53 mm (L-R), and 3.48 mm (A-P). Except for patient 2, all standard deviations of the center phase shift were less than 1 mm. The values of XDT correlation and prediction errors were 1.38±0.65 mm vs. 0.65±0.16 mm (S-I), 1.28±0.48 mm vs. 0.34±0.10 mm (L-R), and 0.96±0.32 mm vs. 0.22±0.072 mm (A-P), respectively. The strong positive correlations were amplitude vs. prediction error, SD of center phase vs. prediction error, and SD of center phase vs. amplitude. The median patient curve-based targeting accuracy was less than 1mm. Additionally, the mean target coverage for all patients with a 3 mm margin was 98.03±1.54%. CONCLUSION This study proved that the diaphragm could be used as a tracking surrogate for liver tumors located in or near the diaphragm instead of placing golden fiducial markers. A reduction in motion amplitude and respiration training were necessary during liver SABR treatment, along with respiration control and evaluation.

PURPOSE/OBJECTIVE(S) Considering the therapeutic toxicity, the question of how to administer adequate chemotherapy to synchronize Stereotactic body radiation therapy (SBRT) treatment strategy for maximizing the benefits of neoadjuvant therapy to improve prognosis is a challenging and debatable issue. This study explores the feasibility and theoretical advantages of the simultaneous implementation of split-course SBRT with systemic treatment. MATERIALS/METHODS We evaluated the effect of three irradiation regimens (conventional radiotherapy (C-R, 15×2 Gy, (D1-5, D8-12, D15-19)), continuous SBRT (C-S, 3×7 Gy, (D1-3)), split SBRT (S-S, 3×7 Gy, (D1, D10, D19)) in combination with systemic therapy (chemotherapy (gemcitabine), PD-1 inhibitor (Anti-mouse PD-1 antibody) and angiogenesis-targeting agent (Anlotinib)) on tumor growth and survival by using the immunologically active C57BL/6 bilateral subcutaneous model with different cancer cells. At different time points after treatment, we monitored changes in the tumor microenvironment and explored the possible mechanisms. RESULTS In the case of radiotherapy alone, we found similar tumor control in all groups but the best survival in the S-S group. When combined with systemic therapy, the S-S group has shown advantages in tumor control and survival. And the S-S combination group induced more CD4+ and CD8+ T lymphocyte infiltration in the tumor, which had the highest number of tumor vessels and the smallest area of hypoxia. Tumor cell PD-L1 expression was increased after radiotherapy in all but the most elevated and persistent S-S combination treatment group. CD3+ T cells, CD4+ T cells and CD8+ T cells peaked at weeks 2-3 after treatment, and all remained at the highest level for 6 weeks in the S-S combination group. Meanwhile, PD-L1 expression was significantly higher in all tumors in the third week than in other groups. The most significant reduction in the hypoxic area and increase in perfusion level was observed in the S-S group in the third week. RNA sequencing analysis revealed that immune response-related pathways were upregulated on the irradiated and non-irradiated side, tumor proliferation and invasion on the non-irradiated side, and angiogenesis-related pathways were down-regulated in the fractionated SBRT combination treatment group. In both irradiated side and non-irradiated side tumor tissues where the abscopal effect was observed, immune response-related pathways were upregulated in the S-S group relative to the C-R group, and tumor proliferation and invasion and angiogenesis-related pathways were found to be downregulated in the non-irradiated side. CONCLUSION In preclinical models, the combination of split SBRT with systemic therapy has been shown to be more advantageous than conventional segmentation, possibly by affecting immune cell infiltration in the tumor microenvironment and reducing tumor hypoxia.

Abstract
BACKGROUND Coronary artery disease (CAD) is the leading cause of death worldwide. The registration of the coronary artery at different phases can help radiologists explore the motion patterns of the coronary artery and assist in the diagnosis of CAD. However, there is no automatic and easy-to-execute method to solve the missing data problem that occurs at the endpoints of the coronary artery tree. This paper proposed a non-rigid multi-constraint point set registration with redundant point removal (MPSR-RPR) algorithm to tackle this challenge. METHODS Firstly, the MPSR-RPR algorithm roughly registered two coronary artery point sets with the pre-set smoothness regularization parameter and Gaussian filter width value. The moving coherent, local feature, and the corresponding relationship between bifurcation point pairs were exploited as the constraints. Next, the spatial geometry information of the coronary artery was utilized to automatically recognize the vessel endpoints and to delete the redundant points of the coronary artery. Finally, the algorithm continued carrying out the multi-constraint registration with another group of the pre-set parameters to improve the alignment performance. RESULTS The experimental results demonstrated that the MPSR-RPR algorithm achieved a significantly lower mean value of the modified Hausdorff distance (MHD) compared to the other state-of-the-art methods for addressing the serious missing data in the left and right coronary arteries. CONCLUSION This study demonstrated the effectiveness of the proposed algorithm in aligning coronary arteries, providing significant value in assisting in the diagnosis of coronary artery and myocardial lesions.

Abstract
PURPOSE/OBJECTIVE(S) Brentuximab vedotin (BV) and immune checkpoint inhibitors (ICIs) had important roles in the treatment of relapse or refractory (R/R) Hodgkin lymphoma (HL). Treatment of refractory disease after BV and -/or ICIs remains a challenge. This study was conducted to evaluate the efficacy and safety of radiotherapy for R/R HL after failure to BV or ICIs. MATERIALS/METHODS We retrospectively analyzed patients in two institutions with R/R HL who had failed after first-line therapy, and were refractory to BV or ICIs, and received radiotherapy (RT) thereafter. The overall response rate (ORR), duration of response (DOR), progression-free survival (PFS) and overall survival (OS) were analyzed. RESULTS A total of 19 patients were enrolled. First-line systemic therapy consisted of ABVD (84.2%), AVD + ICIs (10.5%) and BEACOPP (5.3%), respectively. After first-line therapy, 15 patients (78.9%) were refractory, and 4 patients (21.1%) relapsed. After diagnosis of R/R HL, 8 patients (42.1%) received BV, and 17 patients (89.5%) received ICIs. RT was delivered in all 19 patients who failed after BV or ICIs. In 16 efficacy-evaluable patients, the ORR and CR rate were 100% and 100%. The median DOR was 17.2 months (range, 7.9 to 46.7 months). 3 patients progressed at outside of the radiation field. The in-field-response rate was 100%. The 12-month PFS and OS were 84.4% and 100%, respectively. No patients were reported with sever adverse events. CONCLUSION This study concluded that radiotherapy was effective and safe for refractory HL after BV or ICIs. Further prospective studies were warranted.

Abstract
PURPOSE/OBJECTIVE(S) Spatially fractionated radiation therapy (Lattice) delivers ablative doses to metastatic and/or unresectable tumors with a curative or palliative goal. Through different forms of three-dimensional focusing, lattice forms several spherical high-dose areas(vertices) within the tumor, to produce a more obvious peak-valley effect and limit exposure to surrounding normal tissue. This study aimed to evaluate the efficacy and toxicity of patients with metastatic and/or bulky tumors treated with Lattice radiation. MATERIALS/METHODS Between April 2017 and February 2021, 76 patients with metastatic or bulky tumors treated with spatially-fractionated high-dose external beam radiation using the Lattice technique were included. A median dose of 15 Gy/1 fraction (range 10-45 Gy in 1/3 fractions) was delivered to the vertices in the gross tumor volumes (GTV). 46 patients were treated with Lattice radiation combined with conventional fractionated external irradiation, and 30 patients were treated with Lattice alone. Patients were evaluated for clinical response, survival, and toxicity. RESULTS A total of 76 patients with 85 sites were included in the analysis, 63 (82.9%) patients had metastatic diseases. Median GTV was 138.6cc (range 4.9-3784.1cc) in volume and 6.2 cm (range:2.3-21.4cm) in greatest axial diameter. 38 tumors were in the thorax, 13 abdomen/pelvis, 19 metastatic lymph nodes, 8 bone, 5 head and neck, and 2 extremities. The median follow-up was 11.6 months (range 1.27-57.37 months). At the time of analysis, 23 patients (29.9%) were alive, without the progression of disease. 90.7% of the deceased patients died of disease progression. Median overall survival (OS) was 11.4 months (95% CI: 8.4-17.6), the 1-year OS and cancer specific survival were 46.8% and 48.7% respectively. The disease control rate (DCR) was 91.8%, including 2.4% complete remission, 48.2% partial remission, and 41.2% stable disease. Symptomatic improvement was observed in 98.7% of patients. No mortality was associated with Lattice therapy. There was no treatment-associated acute or late grade 3+ toxicity. CONCLUSION Lattice radiation is feasible and well-tolerated in the treatment of metastatic and/or bulky diseases, and may provide a high DCR. In light of these preliminary results, it seems that this therapy may be a new paradigm for treating patients with advanced cancers.

Abstract
AIM To explore the value of quantitative image features of gadoxetic acid-enhanced magnetic resonance imaging (MRI) for predicting Gglypican-3 (GPC3) expression of single hepatocellular carcinoma (HCC) ≤3 cm. MATERIALS AND METHODS One hundred and forty-nine patients with histopathologically confirmed HCC were included retrospectively. Quantitative image features and clinicopathological parameters were analysed. The significant predictors for GPC3 expression were identified using multivariate logistic regression analyses. Nomograms were constructed from the prediction model and the progression-free survival (PFS) rate was evaluated by the Kaplan-Meier method. RESULTS The tumour-to-liver signal intensity (SI) ratio on the hepatobiliary phase (HBP; odds ratio [OR] = 0.004; p=0.001), serum alpha-fetoprotein (AFP) > 20 ng/ml (OR=6.175; p<0.001), and non-smooth tumour margin (OR=4.866; p=0.002) were independent significant factors for GPC3 expression. When the three factors were combined, the diagnostic specificity was 97.7% (42/43). The nomogram based on the predictive model performed satisfactorily (C-index: 0.852). Kaplan-Meier curves showed that patients with GPC3-positive HCCs have lower PFS rates than patients with GPC3-negative HCCs (Log-rank test, p=0.006). CONCLUSION The tumour-to-liver SI ratio on the HBP combined with serum AFP >20 ng/ml and non-smooth tumour margin are potential predictive factors for GPC3 expression of small HCC ≤3cm. GPC3 expression is correlated with a poor prognosis in HCC patients.

Abstract
PURPOSE/OBJECTIVE(S) To fix uterocervical position, compensate uterocervical intrafraction motion, and thus improve the accuracy of dose delivery based on the robotic system for the treatment of locally advanced cervical cancer with stereotactic body radiotherapy boost. MATERIALS/METHODS CT images were acquired after robot arm implanted a fixator with fiducial markers into the cervix of pelvic phantom. The treatment plans were designed by contoured a simulated tumor lesion site. The fiducial markers position was obtained by real-time image guidance system and was registered with digitally reconstructed radiographs to calculate correlation error of six directions. The correlation error was delivered to the robotic arm to precisely adjust the position and posture of the fixator, and thus compensated uterocervical intrafraction movement through the interactive interface of the robotic system. The pressure sensor at the head of the fixator provided real-time feedback on the pressure value at the contact surface between the fixer and the cervix. The correlation error of six directions and the pressure value were extracted and analyzed from the log file. RESULTS The data from the log file indicated that the three translational direction correlation error of x, y and z were 0.19mm, 0.20mm and 0.10mm, respectively. The three rotational direction correlation error of roll, pitch and yaw were 0.25°, 0.21° and 0.23°, respectively. With the increase of the relative distance between cervix and pressure sensor, the mean value of pressure variation decreases gradually. When the relative distance is 0.5mm and 3mm, the mean value of pressure variation is approximately 76% and 32%, respectively. CONCLUSION The correlation accuracy of the robotic system meets the clinical requirements. The robot arm can fix and monitor the cervical motion in real time during radiotherapy. The robot system adjusts the position of the fixator to correct the uterocervical intrafraction motion error, which is feasible and has good clinical application prospect.

Abstract
More than twenty years ago, multiferroic compounds combining in particular magnetism and ferroelectricity were rediscovered. Since then, BiFeO_{3} has emerged as the most outstanding multiferroic by combining at room temperature almost all the fundamental or applicative properties that may be desired: electroactive spin wave excitations called electromagnons, conductive domain walls, or a low band gap of interest for magnonic devices. All these properties have so far only been discontinuously strain engineered in thin films according to the lattice parameter imposed by the substrate. Here we explore the ferroelectricity and the dynamic magnetic response of BiFeO_{3} bulk under continuously tunable uniaxial strain. Using elasto-Raman spectroscopy, we show that the ferroelectric soft mode is strongly enhanced under tensile strain and driven by the volume preserving deformation at low strain. The magnonic response is entirely modified with low energy magnon modes being suppressed for tensile strain above pointing out a transition from a cycloid to an homogeneous magnetic state. Effective Hamiltonian calculations show that the ferroelectric and the antiferrodistortive modes compete in the tensile regime. In addition, the homogeneous antiferromagnetic state becomes more stable compared to the cycloidal state above a +2% tensile strain close to the experimental value. Finally, we reveal the ferroelectric and magnetic orders of BiFeO_{3} under uniaxial strain and how the tensile strain allows us to unlock and to modify in a differentiated way the polarization and the magnetic structure.

Abstract
Marine group II (MGII) is the most abundant planktonic heterotrophic archaea in the ocean. The evolutionary history of MGII archaea is elusive. In this study, 13 new MGII metagenome-assembled genomes were recovered from surface to the hadal zone in Challenger Deep of the Mariana Trench; four of them from the deep ocean represent a novel group. The optimal growth temperature (OGT) of the common ancestor of MGII has been estimated to be at about 60°C and OGTs of MGIIc, MGIIb, and MGIIa at 47°C-50ºC, 37°C-44ºC, and 30°C-37ºC, respectively, suggesting the adaptation of these species to different temperatures during evolution. The estimated OGT range of MGIIc was supported by experimental measurements of cloned β-galactosidase that showed optimal enzyme activity around 50°C. These results indicate that MGIIc may have originated from a common ancestor that lived in warm or even hot marine environment, such as hydrothermal vents.

Abstract
Objective: To explore the utilization of cancer-related data from basic medical insurance databases in China, and promote the application of medical insurance data in cancer prevention and treatment. Methods: Database PubMed, Web of Science, Wanfang, and CNKI were used to select related research papers using data from basic medical insurance system in China published by December 2021. Descriptive analysis was conducted in terms of the number of publications, types of cancer, primary research contents and author affiliations. Results: A total of 65 papers were included in the study. The number of publications increased rapidly after 2016. The most studied cancer type was lung cancer, and healthcare costs were the most common research contents. Fujian, Beijing, and Anhui have made a better use of cancer-related medical insurance databases compared to other provincial regions. The accessibility of the New Rural Cooperative Medical Scheme data was limited due to the high regional barriers, while the accessibility of the urban basic medical insurance data was relatively high. The researchers from Peking University and Fudan University had higher utilization of basic medical insurance data compared with those from other institutions. Conclusions: The utilization of cancer-related data from basic medical insurance databases in China is limited because of poor accessibility, insufficient data sharing, and regional restrictions. Thus, it is urgent to improve data accessibility and promote the integration and utilization of regional medical insurance data.

Abstract
Objective: To explore the association of different obesity measurement indexes on serum C-reactive protein (CRP) in Chinese adult women. Methods: The data were obtained from baseline and follow-up surveys of the urban Breast Cancer Screening Program in Shuangliu District, Chengdu. A total of 441 adult women were included in the study. A questionnaire survey, physical examination, and laboratory testing were conducted on the subjects. Multivariate logistic regression model, two-level mixed effects logistic regression model, and restricted cubic spline method were used to investigate the linear and nonlinear correlation between different obesity measurement indexes and serum CRP in adult women. Results: For every 1 unit increase in BMI, waist circumference (WC), and adiposity, the risk of elevated serum CRP or exacerbation of chronic low-grade inflammation in adult women increased by 16.5%, 5.0%, and 11.1% (P<0.05), respectively. Both BMI and adiposity were nonlinear correlated with serum CRP. Using BMI=24.0 kg/m2 as the reference point, serum CRP level increased with the increase of BMI when BMI >24.0 kg/m2. Using adiposity=30% as the reference point, serum CRP level increased with the increase of adiposity when adiposity >30%. Conclusions: Overall, obesity reflected by BMI had the strongest association with serum CRP in adult women, followed by body fat content reflected by adiposity, and central obesity reflected by WC had the weakest association with CRP. Adult women with BMI >24.0 kg/m2 or adiposity >30% are at high risk for obesity-related inflammatory manifestations.

Abstract
Objective: To investigate the familial heritability of endometriosis and to compare the clinical characteristics of patients with or without a family history of endometriosis. Methods: From January 2020 to June 2022, 850 patients with endometriosis confirmed by laparotomy or laparoscopy in Peking University Third Hospital were included in this study. Clinical data were collected, family history was followed up, and the differences of clinical indicators between patients with and without family history of endometriosis were compared. Results: A total of 850 patients were enrolled, with an average age of (33.8±7.0) years old, 315 (37.1%, 315/850) patients in stage Ⅲ and 496 (58.4%, 496/850) patients in stage Ⅳ. There were 100 patients with family history of endometriosis, accounting for 11.8% (100/850). Most of the 113 relatives involved were mothers, daughters and sisters (76.1%, 86/113), 81.5% (22/27) of the second and third degree relatives were maternal relatives. The median ages of patients with and without family history of endometriosis were 30 and 33 years old respectively at the time of diagnosis. The unmarried rate of patients with family history was higher [42.0% (42/100) vs 26.3% (197/750)]. The percentage of dysmenorrhea patients with family history was higher [89.0% (89/100) vs 55.5% (416/750)]. The medians of dysmenorrhea score in patients with and without family history were 6 and 2, and the median durations of dysmenorrhea were 10 and 1 years. There were significant differences in age, marital status, percentage of dysmenorrhea, dysmenorrhea score and duration (all P<0.001). The median levels of serum cancer antigen (CA) 125 in patients with family history and patients without family history at the time of diagnosis were 57.5 and 46.9 kU/L respectively, with a statistically significant difference (P<0.05). However, there were no significant differences between the two groups in nationality, bady mass index, menarche age, menstrual cycle, menstrual period, menstrual volume, serum CA19-9 level, cyst location and size, stage, history of adverse pregnancy and childbirth, infertility, adenomyosis and deep infiltrating endometriosis (all P>0.05). By comparing the specific conditions of dysmenorrhea patients with and without family history of endometriosis, there were no significant differences between the two groups in terms of the age of onset of dysmenorrhea, duration of dysmenorrhea, primary and secondary dysmenorrhea, and progressive aggravation of dysmenorrhea (all P>0.05). The difference in the degree of dysmenorrhea in dysmenorrhea patients with family history of endometriosis was significant (P<0.001). Conclusions: The incidence of endometriosis has a familial tendency, and most of the involved relatives are the first degree relatives. Compared with patients without family history of endometriosis, endometriosis patients with family history are diagnosed at an earlier age, with higher percentage of dysmenorrhea, had more severe dysmenorrhea and higher serum CA125 level.

Abstract
In this study, we investigate the spatiotemporal dynamics of the neural oscillations by analyzing the electric potential that arises from neural activity. We identify two types of dynamics based on the frequency and phase of oscillations: standing waves or as out-of-phase and modulated waves, which represent a combination of standing and moving waves. To characterize these dynamics, we use optical flow patterns such as sources, sinks, spirals and saddles. We compare analytical and numerical solutions with real EEG data acquired during a picture-naming task. Analytical approximation of standing waves helps us to establish some properties of pattern location and number. Specifically, sources and sinks are mainly located in the same location, while saddles are positioned between them. The number of saddles correlates with the sum of all the other patterns. These properties are confirmed in both the simulated and real EEG data. In particular, source and sink clusters in the EEG data overlap with each other with median percentages around 60%, and hence have high spatial correlation, while source/sink clusters overlap with saddle clusters in less than 1%, and have different locations. Our statistical analysis showed that saddles account for about 45% of all patterns, while the remaining patterns are present in similar proportions.

Abstract
Healthy aging leads to poorer performance in upper limb (UL) daily living movements. Understanding the neural correlates linked with UL functional movements may help to better understand how healthy aging affects motor control. Two non-invasive neuroimaging methods allow for monitoring the movement-related brain activity: functional near-infrared spectroscopy (fNIRS) and electroencephalography (EEG), respectively based on the hemodynamic response and electrical activity of brain regions. Coupled, they provide a better spatiotemporal mapping. The aim of this study was to evaluate the effect of healthy aging on the bilateral sensorimotor (SM1) activation patterns of functional proximal UL movements. Twenty-one young and 21 old healthy participants realized two unilateral proximal UL movements during: i) a paced reaching target task and ii) a circular steering task to capture the speed-accuracy trade-off. Combined fNIRS-EEG system was synchronised with movement capture system to record SM1 activation while moving. The circular steering task performance was significantly lower for the older group. The rate of increase in hemodynamic response was longer in the older group with no difference on the amplitude of fNIRS signal for the two tasks. The EEG results showed aging related reduction of the alpha-beta rhythms synchronisation but no desynchronisation modification. In conclusion, this study uncovers the age-related changes in brain electrical and hemodynamic response patterns in the bilateral sensorimotor network during two functional proximal UL movements using two complementary neuroimaging methods. This opens up the possibility to utilise combined fNIRS-EEG for monitoring the movement-related neuroplasticity in clinical practice.

Abstract
Objective: To investigate the pathogenic characteristics, bacteriological diagnosis time and its associated factors among patients with nontuberculous mycobacterial (NTM) lung disease in a large tuberculosis-designated hospital in Shanghai from 2020 to 2021, in order to improve diagnosis efficiency and formulate precision treatment. Methods: On the basis of the Tuberculosis Database in Shanghai Pulmonary Hospital, NTM patients diagnosed by the Department of Tuberculosis between January 2020 and December 2021 were screened. Demographic, clinical and bacterial information were retrospectively collected. Chi-square test, paired-sample nonparametric test and logistic regression model were used to analyze the factors associated with the diagnosis time of NTM lung disease. Results: A total of 294 patients with bacteriologically confirmed NTM lung disease were included in this study, 147 males and 147 females with a median age of 61(46, 69) years. Of them, 227 (77.2%) patients had comorbidity of bronchiectasis. Species identification results showed that Mycobacterium Avium-Intracellulare Complex was the main pathogen of NTM lung disease (56.1%), followed by Mycobacterium kansasii (19.0%) and Mycobacterium abscessus (15.3%). Species such as Mycobacterium xenopi and Mycobacterium malmoense were rarely identified, accounting for a total proportion of only 3.1%. Positive culture rates for sputum, bronchoalveolar lavage fluid and puncture fluid were 87.4%, 80.3% and 61.5%, respectively. Paired-sample analysis showed that the positive rate of sputum culture was significantly higher than that of smear microscopy (87.1% vs. 48.4%, P<0.01), while no statistical difference was observed between sputum and bronchoalveolar lavage fluid on positive culture rate (78.7% vs. 77.3%, P>0.05). Patients with cough or expectoration were observed with 4.04-fold (95%CI 1.80-9.05) or 2.95-fold (95%CI 1.34-6.52) higher probability of positive sputum culture, compared to those without. Regarding bronchoalveolar lavage fluid, female or patients with bronchiectasis had a 2.82-fold (95%CI 1.16-6.88) or 2.38-fold (95%CI 1.01-5.63) higher probability to achieve a positive culture. The median time to diagnosis of NTM lung disease was 32 (interquartile range: 26-42) days. The results of multivariable analysis showed that patients with symptom of expectoration (aOR=0.48, 95%CI 0.29-0.80) needed a shorter diagnosis time in comparison with patients without expectoration. With Mycobacterium Avium-Intracellulare Complex as a reference, lung disease caused by Mycobacterium abscessus needed shorter diagnosis time (aOR=0.43, 95%CI 0.21-0.88), whereas those caused by rare NTM species were observed to require a longer diagnosis time (aOR=8.31, 95%CI 1.01-68.6). Conclusion: The main pathogen causing NTM lung disease in Shanghai was Mycobacterium Avium-Intracellulare Complex. Sex, clinical symptoms and bronchiectasis had an impact on the positive rate of mycobacterial culture. The majority of patients in study hospital were timely diagnosed. Clinical symptoms and NTM species were associated with the bacteriological diagnosis time of NTM lung disease.

Abstract
In recent years, the incidence of renal cancer has been increasing continuously. Surgical resection is the "gold standard" for the treatment of small renal cancer. However, local ablation therapy of renal cancer is undoubtedly the best choice for patients with short life expectancy, other complications, and impaired renal function who are not suitable for surgery. In recent years, with the development of ablation techniques and long-term follow-up, local ablation has shown good therapeutic effects. As many domestic hospitals are performing or planning to perform renal tumor cryoablation to improve the clinical cure rate and surgical safety of renal tumor cryoablation, it is necessary to standardize the surgical indications, contraindications, perioperative management, efficacy evaluation, and other common problems. Currently, there is no expert consensus regarding perioperative renal tumor cryoablation in China. To standardize the perioperative management of renal tumor cryoablation and related technical operations in clinical practice, and improve the effectiveness and safety of cryoablation, the expert committee of Tumor Interventional and Minimally Invasive Diagnosis and Treatment Continuing Education Base of the Chinese Anti-Cancer Association convened experts in related fields to discuss and formulate this consensus, which is hereby published, for clinical reference and application.

Abstract
Estuaries are one of the most highly productive and economically important ecosystems at the continent-ocean interface. Estuary productivity is largely determined by the microbial community structure and activity. Viruses are major agents of microbial mortality and are key drivers of global geochemical cycles. However, the taxonomic diversity of viral communities and their spatial-temporal distribution in estuarine ecosystems have been poorly studied. In this study, we investigated the T4-like viral community composition at three major Chinese estuaries in winter and in summer. Diverse T4-like viruses, which were divided into three main clusters (Clusters I to III), were revealed. The Marine Group of Cluster III, with seven identified subgroups, was the most dominant (averaging 76.5% of the total sequences) in the Chinese estuarine ecosystems. Significant variations of T4-like viral community composition were observed among estuaries and seasons, with higher diversity occurring in winter. Among various environmental variables, temperature was a main driver of the viral communities. This study demonstrates viral assemblage diversification and seasonality in Chinese estuarine ecosystems. IMPORTANCE Viruses are ubiquitous but largely uncharacterized members of aquatic environments that cause significant mortality in microbial communities. Recent large-scale oceanic projects have greatly advanced our understanding of viral ecology in marine environments, but those studies mostly focused on oceanic regions. There have yet to be spatiotemporal studies of viral communities in estuarine ecosystems, which are unique habitats that play a significant role in global ecology and biogeochemistry. This work is the first comprehensive study that provides a detailed picture of the spatial and seasonal variation of viral communities (specifically, T4-like viral communities) in three major estuarine ecosystems in China. These findings provide much-needed knowledge regarding estuarine viral ecosystems, which currently lags in oceanic ecosystem research.

Abstract
Objective: To investigate the clinical features and long-term prognostic factors of diabetic patients with low or intermediate complexity coronary artery disease (CAD) post percutaneous coronary intervention (PCI). Methods: This was a prospective, single-centre observational study. Consecutive diabetic patients with SYNTAX score (SS)≤32 undergoing PCI between January and December 2013 in Fuwai hospital were included in this analysis. The patients were divided into two groups based on SS, namely SS≤22 group and SS 23-32 group. Multivariate Cox regression analysis was performed to identify independent factors related to poor 5-year prognosis. The primary outcomes were cardiac death and recurrent myocardial infarction, the secondary outcomes were all cause death and revascularization. Results: Of the 3 899 patients included in the study, 2 888 were men (74.1%); mean age was 59.4±9.8 years. There were 3 450 patients in the SS≤22 group and 449 patients in the SS 23-32 group. Compared with SS≤22 group, the incidence of revascularization was higher in SS 23-32 group (18.9% (85/449) vs. 15.2% (524/3450), log-rank P=0.019). There was no significant difference in all-cause death, cardiac death and recurrent myocardial infarction between the two groups (log-rank P>0.05). Multivariate Cox regression analysis showed that age (HR=1.05, 95%CI 1.02-1.08, P<0.001), chronic obstructive pulmonary disease (HR=3.12, 95%CI 1.37-7.07, P=0.007) and creatinine clearance rate (CCr)<60 ml/min (HR=3.67, 95%CI 2.05-6.58, P<0.001) were independent risk factors for 5-year cardiac death, while left ventricular ejection fraction (HR=0.94, 95%CI 0.91-0.96, P<0.001) was a protective factor. Previous PCI (HR=2.04, 95%CI 1.38-3.00, P<0.001), blood glucose level≥11.1 mmol/L on admission (HR=2.49, 95%CI 1.32-4.70, P=0.005) and CCr<60 ml/min (HR=1.85, 95%CI 1.14-2.99, P=0.012) were independent risk factors for 5-year recurrent myocardial infarction. The SS of 23-32 was independently associated with risk of revascularization (HR=1.54, 95%CI 1.09-2.16, P=0.014), after adjusting for residual SS. Residual SS was not a risk factor for 5-year prognosis. Conclusions: In diabetic patients with low-or intermediate complexity CAD, SS 23-32 is associated with increased risk of 5-year revascularization; the clinical characteristics of the patients are associated with the long-term mortality and recurrent myocardial infarction, but not related to revascularization.

Abstract
INTRODUCTION The aim of the study was to explore the clinical effect of brain and heart health managers combined with the "SMG" health management mode on nursing intervention in ischemic stroke patients. MATERIAL AND METHODS A total of 187 ischemic stroke patients divided into 96 patients in the observation group and 91 patients in the control group with the random number table method. The control group conducted the routine care intervention, and the observation group used the brain and heart health managers combined with the "SMG" health management model for the nursing intervention. The control of stroke risk factors was explored by comparing blood pressure, blood glucose and blood lipid and other indicators between the two groups before and after treatment. RESULTS Compared with that before the intervention, the Stroke Self-Efficacy Questionnaire (SSEQ) score of both the observation group and the control group were significantly higher ( p < 0.05), and the Hamilton Anxiety Scale (HAMA), Hamilton Depression Scale (HAMD), National Institutes of Health Stroke Scale (NIHSS) and modified Rankin scale (mRS) scores were all decreased ( p < 0.05). The proportion of patients with treatment adherence did not differ significantly before and after the intervention in the control group ( p > 0.05), and it increased significantly in the observation group after the intervention ( p < 0.05). The observation group had higher SSEQ score and lower HAMA, HAMD, NIHSS, and mRS scores after the intervention compared with the control group, with statistically significant differences. CONCLUSIONS The combination of brain and heart health managers and "SMG" is more conducive to improving the selfefficacy of ischemic stroke patients, alleviating patient anxiety and depression, improving patient treatment compliance, controlling stroke risk factors, and promoting neurological function recovery.

Abstract
Marine group II (MGII) archaea (Ca. Poseidoniales) are among the most abundant microbes in global oceanic surface waters and play an important role in driving marine biogeochemical cycles. Magroviruses - the viruses of MGII archaea have been recently found to occur ubiquitously in surface ocean. However, their diversity, distribution, and potential ecological functions in coastal zones especially brackish waters are unknown. Here we obtained 234 non-redundant magroviral genomes from brackish surface waters by using homology searches for viral signature proteins highlighting the uncovered vast diversity of this novel viral group. Phylogenetic analysis based on these brackish magroviruses along with previously reported marine ones identified six taxonomic groups with close evolutionary connection to both haloviruses and the viruses of Marine Group I archaea. Magroviruses were present abundantly both in brackish and open ocean samples with some showing habitat specification and others having broad spectrums of distribution between different habitats. Genome annotation suggests they may be involved in regulating multiple metabolic pathways of MGII archaea. Our results uncover the previously overlooked diversity and ecological potentials of a major archaeal virial group in global ocean and brackish waters and shed light on the cryptic evolutionary history of archaeal viruses.

Abstract
OBJECTIVE To explore the effects of cluster nursing on self-care ability, length of hospital stay, complications and neurological function of patients with mechanical thrombectomy of large vessel occlusion in acute cerebral infarction. METHODS A total of 83 patients with acute cerebral infarction who underwent thrombolectomy in a tertiary hospital in Anhui Province from June 2019 to March 2021 were randomly divided into observation group and control group. The observation group was treated with cluster nursing intervention mode, and the control group was treated with routine nursing mode. Barthel index scores and National Institute of Health Stroke Scale (NIHSS) scores were compared between the two groups at admission and at 1 week, 1 month and 3 months of nursing intervention. The length of stay and incidence of complications were compared between the two groups. RESULTS There was no significant difference in baseline data, Barthel index and NIHSS score between the two groups at admission (P>0.05). The Barthel index at 1 week, 1 month and 3 months after operation in the observation group was significantly higher than that in the control group (P<0.05), while the NIHSS score, incidence of complications and length of hospital stay were significantly lower than those of the control group (P<0.05). CONCLUSION Cluster nursing can improve the neurological function, improve the self-care ability, reduce the incidence of complications, shorten the hospitalization period, improve the prognosis and promote the recovery of patients with acute cerebral infarction thrombolysis.

Abstract
Estuaries are important ecosystems providing irreplaceable services for humankind and, in turn, are extensively influenced by human activities and climate changes. Microbial processes, which are largely controlled by viruses, are always responsible for the ecological function and environmental problems in estuaries. However, we know little about the ecology and importance of viruses in estuarine systems. Here, we investigated viral ecological dynamics in estuarine systems on local (four largest estuaries in China in different seasons) and global scales. Viral production varied by almost 20-fold in Chinese estuaries with significant seasonality, being responsible for the removal of 1.41%-21.45% of the bacterioplankton standing stock each day, and contributed directly to the organic carbon pool by releasing an average of 3.57 µg of cellular carbon per liter per day. By compiling data from 21 estuaries across the world, we found for the first time that viral population size peaked at mid-latitude and viral production increased towards the equator in estuarine ecosystems. The results indicated the higher viral impact on microbial mortality and dissolved organic matter cycling in tropical estuaries. Our field investigation and global synthesized analysis provide compelling evidence of spatiotemporal variations in estuarine viral dynamics. The global view of viral impacts on estuarine microbial mortality offers important insight for incorporating viruses into ecological models and understanding the environmental implications of the tropicalization of temperate aquatic ecosystems under a scenario of climate warming.

Abstract
Abstract
Introduction
Obesity leads to an increased risk of cardiovascular disease (CVD) morbidity and mortality and is associated with the metabolic risk factors such as hypertension, diabetes mellitus, hyperlipidemia [1]. Metabolic surgery has been proven to be the most effective long term weight management tool and has known benefits in CVD prevention [2]. Global longitudinal strain (GLS) is an effective quantitative measurement of left ventricular (LV) function that is also a powerful predictor of future CVD events and mortality [3]. The impact of metabolic surgery on LV structure and function is unknown.
Purpose
This study investigated the changes in cardiac structure and function after metabolic surgery, including GLS. To our knowledge there has not been a study investigating this relationship previously reported.
Methods
Consecutive patients undergoing metabolic surgery at our center between March 2005 and February 2019 were recruited. Patients with transthoracic echocardiographic imaging (TTE) pre and post metabolic surgery (May 2005 to January 2019) were included. Electronic medical records were searched to obtain demographic, surgical and clinical data. GLS was calculated with Velocity Vector Imaging (VVI, Siemens, v2.0, Pennsylvania, USA). Averaged GLS values were derived from 4 chamber, 2 chamber and 3 chamber calculations.
Results
398 patients with pre- and post-operative cardiac imaging were included. Please see Table 1 for the baseline demographics of our study population. The mean age was 60.0 years with 70% being female. There were significant rates of CVD risk factors such as: hypertension (76.4%), diabetes mellitus (58.8%) and hyperlipidemia (76.4%).
The clinical and echocardiographic changes noted post metabolic surgery are detailed in Table 2. Along with decreases in weight post operatively, there were significant improvements in the markers of CVD risk factors such as mean blood pressure (134/75 to 129/72 mmHg, p value <0.001), mean gylcated hemoglobin levels (7.0 to 6.1%, p value <0.001) and mean low density lipoprotein (LDL) levels (97.7 to 88.2 mg/dl, p value <0.001).
There were a number of statistically significant positive changes in the left ventricular structure and function. The mean LV ejection fraction increased from 56.3% to 57.4% (p=0.008); left ventricular mass decreased from 238.2 g to 179.3 g (p value <0.001), and both septal and posterior wall thicknesses decreased significantly (p value <0.001). The LV mass indexed to body surface area (BSA) also decreased from 93.5 g/m2 to 83.1 g/m2.
The average global LV GLS was −15.7% pre-operatively, improving significantly to −17.9% post-operatively (p<0.001).
Conclusion
Our study has shown for the first time the impact of metabolic surgery on ventricular structure and function, with reduction in LV mass and improvement in LV GLS. These novel findings lends further support to the cardiovascular benefits of metabolic surgery.

Abstract
OBJECTIVE The purpose of this review was to collect data from the literature to assess the impact of preoperative anemia on complications after total joint arthroplasty (TJA). MATERIALS AND METHODS We conducted a literature search on the websites of PubMed, Scopus, CENTRAL, Embase, and Google Scholar for comparative TJA studies reporting complication rates based on the presence of anemia. The last search was conducted on the 15th of May 2022. Studies only on hip and knee replacements were eligible for inclusion. RESULTS Twelve studies with 1,463,813 patients published between 2012-2022 were included. Meta-analysis indicated that anemic patients had increased risk of mortality (OR: 2.85 95% CI: 1.89, 2.48 I2=83% p<0.00001), wound complications (OR: 2.06 95% CI: 3.51, 2.48 I2=99% p=0.008), cardiac complications (OR: 2.40 95% CI: 1.56, 3.68 I2=98% p<0.0001), respiratory complications (OR: 2.46 95% CI: 1.10, 5.50 I2=100% p=0.03), renal complications (OR: 2.84 95% CI: 1.39, 5.80 I2=99% p=0.004), sepsis (OR: 3.93 95% CI: 1.15, 13.45 I2=99% p=0.03), urinary complications (OR: 2.42 95% CI: 1.27, 4.59 I2=100% p=0.007), and readmission rates (OR: 1.58 95% CI: 1.42, 1.76 I2=66% p<0.00001) as compared to non-anemic patients undergoing TJA. Most results did not change on sensitivity analysis. There were some non-significant results on subgroup analysis based on joint type and definition of anemia. CONCLUSIONS Our review suggests that preoperative anemia leads to increased morbidity and mortality after TJA. Specifically, anemia increases the risk of wound, cardiac, respiratory, renal, and urinary complications along with a higher incidence of sepsis and readmissions. Results should be interpreted with caution due to the high heterogeneity in the meta-analyses.

Abstract
Abstract
Background
To explore the prevalence, outcome and perinatal risks of neonatal hypoxemic respiratory failure (NRF) in a survey of all livebirths from a regional network of perinatal-neonatal care during the transition period after 5-year universal health insurance implemented in China.
Methods
Clinical data of all neonatal respiratory morbidities in Huai’an were retrospectively collected in the regional perinatal network database of all livebirths as vital statistics in 2015. NRF was defined as hypoxemia requiring continuous positive airway pressure (CPAP) and/or mechanical ventilation (MV) for at least 24 h. Mortality risks of antenatal and perinatal morbidities, major respiratory therapies and complications were analyzed by multivariable logistic regression model.
Results
There were 788 NRF cases identified in 9.9% (7960) hospitalized, or 13.3‰ (59056) livebirths, in which 6.7% received intensive care and 93.0% critical care. The major underlying morbidities were respiratory distress syndrome (RDS, 36.4%) and pneumonia/sepsis (35.3%), treated mainly by CPAP, MV and surfactant. Significantly improved outcomes by surfactant in RDS were in patients with birthweight (BW) < 1500 g or gestational age (GA) < 32 weeks. The overall mortality rate in NRF was 18.4% whereas for those of BW < 1000 g and GA < 28 weeks, 70% and 54%, respectively. The multivariable regression analysis showed the highest odds for NRF death among meconium aspiration syndrome, congenital anomalies, BW < 1500 g and necrotizing enterocolitis, whereas born in level III hospitals, cesarean delivery, CPAP and MV were associated with markedly reduced death odds.
Conclusions
The salient findings with associated risk estimates reflected efficiency of respiratory support as critical care in a prefectural regional network infrastructure for annual livebirths in 5.6 million inhabitants. It implicated the representativeness of contemporaneous perinatal-neonatal care standard at medium to medium-high level, in one/fourth of the population of China, aiming at saving more life of very critical and preterm infants for better survival.
