Abstract
Ultrasound-stimulated contrast agents have gained significant attention in the field of tumor treatment as drug delivery systems. However, their limited drug-loading efficiency and the issue of bulky, imprecise release have resulted in inadequate drug concentrations at targeted tissues. Herein, we developed a highly efficient approach for doxorubicin (DOX) precise release at tumor site and real-time feedback via an integrated strategy of "programmable ultrasonic imaging guided accurate nanodroplet destruction for drug release" (PND). We synthesized DOX-loaded nanodroplets (DOX-NDs) with improved loading efficiency (15 %) and smaller size (mean particle size: 358 nm). These DOX-NDs exhibited lower ultrasound activation thresholds (2.46 MPa). By utilizing a single diagnostic transducer for both ultrasound stimulation and imaging guidance, we successfully vaporized the DOX-NDs and released the drug at the tumor site in 4 T1 tumor-bearing mice. Remarkably, the PND group achieved similar tumor remission effects with less than half the dose of DOX required in conventional treatment. Furthermore, the ultrasound-mediated vaporization of DOX-NDs induced tumor cell apoptosis with minimal damage to surrounding normal tissues. In summary, our PND strategy offers a precise and programmable approach for drug delivery and therapy, combining ultrasound imaging guidance. This approach shows great potential in enhancing tumor treatment efficacy while minimizing harm to healthy tissues.

Abstract
AIM To evaluate the prevalence, aetiology, and corresponding morbidity of coronary microvascular dysfunction (CMD) in patients with suspected myocardial ischaemia. MATERIALS AND METHODS The present study included 115 patients with suspected myocardial ischaemia who underwent stress perfusion cardiac magnetic resonance imaging. CMD was assessed visually based on the myocardial perfusion results. The CMR-derived myocardial perfusion reserve index (MPRI) and left ventricular (LV) strain parameters obtained using the post-processing software CVI42 were employed to evaluate LV myocardial perfusion and deformation. LV strain parameters included global longitudinal, circumferential, and radial strain (GLS, GCS, and GRS), global systolic/diastolic longitudinal, circumferential, and radial strain rates (SLSR, SCSR, SRSR, DLSR, DCSR, and DRSR). RESULTS Of the 115 patients, 12 patients were excluded and 103 patients were finally included in the study. CMD was observed in 79 % (81 patients, aged 53 ± 12 years) of patients. Regarding aetiology, 91 (88 %) patients had non-obstructive coronary artery disease (CAD), eight (8 %) had obstructive CAD, and four (4 %) had hypertrophic cardiomyopathy (HCM). The incidence of CMD was highest (100 %) in patients with HCM, followed by those with non-obstructive CAD (up to 79 %). There were no statistical differences between CMD and non-CMD groups in GCS, GRS, GLS, SRSR, SCSR, SLSR, DCSR, DRSR and DLSR. CONCLUSION The incidence of CMD was higher in patients with signs and symptoms of ischaemia. CMD occurred with non-obstructive CAD, obstructive CAD, and HCM, with the highest prevalence of CMD in HCM.

Abstract
Artificial photosynthesis provides a sustainable strategy for producing usable fuels and fine chemicals and attracts broad research interest. However, conventional approaches suffer from low reactivity or low selectivity. Herein, we demonstrate that photocatalytic reduction of CO2 coupled with selective oxidation of aromatic alcohol into corresponding syngas and aromatic aldehydes can be processed efficiently and fantastically over the designed S-scheme ZnIn2S4@CdS core-shell hollow nanocage under visible light. In the ZnIn2S4@CdS heterostructure, the photoexcited electrons and holes with weak redox capacities are eliminated, while the photoexcited electrons and holes with powder redox capacities are separated spatially and preserved on the desired active sites. Therefore, even if there are no cocatalysts and no vacancies, ZnIn2S4@CdS exhibits high reactivity. For instance, the CO production of ZnIn2S4@CdS is about 3.2 and 3.4 times higher than that of pure CdS and ZnIn2S4, respectively. More importantly, ZnIn2S4@CdS exhibits general applicability and high photocatalytic stability. Trapping agent experiments, 13CO2 isotopic tracing, in situ characterizations, and theoretical calculations reveal the photocatalytic mechanism. This study provides a new strategy to design efficient and selective photocatalysts for dual-function redox reactions by tailoring the active sites and regulating vector separation of photoexcited charge carriers.

Abstract
Rationale: Cancer treatment outcome is traditionally evaluated by tumor volume change in clinics, while tumor microvascular heterogeneity reflecting tumor response has not been fully explored due to technical limitations. Methods: We introduce a new paradigm in super-resolution ultrasound imaging, termed pattern recognition of microcirculation (PARM), which identifies both hemodynamic and morphological patterns of tumor microcirculation hidden in spatio-temporal space trajectories of microbubbles. Results: PARM demonstrates the ability to distinguish different local blood flow velocities separated by a distance of 24 μm. Compared with traditional vascular parameters, PARM-derived heterogeneity parameters prove to be more sensitive to microvascular changes following anti-angiogenic therapy. Particularly, PARM-identified "sentinel" microvasculature, exhibiting evident structural changes as early as 24 hours after treatment initiation, correlates significantly with subsequent tumor volume changes (|r| > 0.9, P < 0.05). This provides prognostic insight into tumor response much earlier than clinical criteria. Conclusions: The ability of PARM to noninvasively quantify tumor vascular heterogeneity at the microvascular level may shed new light on early-stage assessment of cancer therapy.

Abstract
In this paper, a new preparation technology is developed to make high-alumina coal gangue (HACG) auxiliary cementitious admixture by calcining HACG-Ca(OH)2 (CH) mixture. HACG powders mixed with 20 wt.% CH were calcined within a temperature range of 600-900 °C, and the thermal transformation and mineral phase formation were analyzed. The hydration reaction between activated HACG-CH mixture and cement was also investigated. The results showed that HACG experienced a conventional transformation from kaolinite to metakaolin at 600 °C and finally to mullite at 900 °C, whereas CH underwent an unexpected transformation process from CH to CaO, then to CaCO3, and finally to CaO again. These substances' states were associated with the dehydroxylation of CH, the chemical reaction between CaO and CO2 generating from the combustion of carbon in HACG, and the decomposition of CaCO3, respectively. It is the formation of a large amount of CaO above 800 °C that favors the formation of hydratable products containing Al2O3 in the calcining process and C-A-H gel in the hydration process. The mechanical properties of HACG-cement mortar specimens were measured, from which the optimal calcination temperature of 850 °C was determined. As compared with pure cement mortar specimens, the maximum 28-d flexural and compressive strengths of HACG-cement mortar specimens increased by 5.4% and 38.2%, respectively.

Abstract
Bilateral uterine artery ligation (BUAL) serves as an effective surgical devascularization procedure in obstetric emergencies. However, concerns regarding the impact of uterine devascularization have evoked dispute. Here, the fetal growth index and obstetrical outcomes during the subsequent pregnancy of women who had undergone BUAL during cesarean section are reported. The case series of women who underwent BUAL during cesarean section and had another delivery later at the Xiamen Women and Children's Hospital between 2011 and 2020 is described. Pregnancies that did not continue beyond 20 weeks of gestation were excluded. Cases were identified from neonatal and obstetric databases and the clinical data of all cases were extracted. A total of 12 cases were identified retrospectively. Fetal biometric parameters of subsequent pregnancies in all cases including biparietal diameter, head circumference, abdominal circumference, and femur length are presented graphically across the different gestational ages and were all within the range of the 3rd-97th percentile. No maternal or neonatal morbidity was observed. BUAL did not appear to compromise a woman's subsequent obstetric outcomes. As a safe and simple surgical technique, it is safe to recommend BUAL in clinical practice.

Abstract
AIM To explore the feasibility of a "triple-low" dose (low tube voltage, low tube current, and low contrast agent volume) bronchial artery computed tomography (CT) angiography (CTA) to replace routine dose bronchial artery CTA before bronchial artery embolisation (BAE). MATERIALS AND METHODS CTA was obtained from 60 patients with body mass index (BMI) < 30 kg/m2 using a 256 multi-section iCT system, and they were divided into two groups: (1) group A: 100 kVp, 100 mAs, 50 ml contrast medium (CM); (2) group B: 120 kVp, automatic tube current modulation (ACTM), 80 ml CM. CT attenuation of the thoracic aorta, image noise, signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR) were calculated, and subjective image quality scores and traceability scores assessed. The effective radiation dose was calculated. RESULTS The radiation dose was reduced by 79.7% in group A compared to group B (p<0.05). The CT attenuation of the thoracic aorta was increased by approximately 13% in group A compared to group B (p<0.05). Higher image noise, lower SNR, and CNR were obtained in group A compared to group B (all p<0.05). Both subjective image quality scores and traceability scores did not differ between groups A and B (both p>0.05). CONCLUSION It is feasible to use the "triple-low" dose CTA protocol for patients with a body mass index (BMI) < 30 kg/m2. The radiation dose was reduced by 79.7%, and the dose of contrast medium was reduced by 37.5% to ensure the diagnostic value.

Abstract
This study aimed to compare the efficacy of different doses of femoston with expectant management in patients with incomplete abortions. Patients diagnosed with incomplete abortion were included if they chose to continue medical treatment after relevant contraindications were excluded. Participants were divided into 3 groups: the femoston (1/10) and femoston (2/10) groups received different doses of femoston, and patients in the control group received expectant treatment. The success rate of complete abortion and the rate of menstrual recovery among the 3 groups were compared to evaluate the efficacy of different doses of femoston in patients with incomplete abortions. A total of 197 patients were analyzed: 73 in the femoston (1/10) group, 73 in the femoston (2/10) group, and 51 patients were followed up without treatment in the control group. The femoston group was significantly more effective than the control group P < .0001). The adjusted odds ratio (OR) and 95% confidence interval (CI) were 3.103 and 1.153 to 8.350 (P = .025). The success rate of complete abortion in the femoston (2/10) group was significantly higher than that in the femoston (1/10) group (adjusted OR: 0.403, 95% CI: 0.145-1.118, P = .081). In addition, the rate of menstrual recovery in the femoston group was significantly higher than that in the control group (P = .007), and the rate in the femoston (2/10) group was also higher than the femoston (1/10) group with statistically significant (P = .001). Femoston is effective in treating incomplete abortion, with femostons containing 2 mg estrogen being more effective. Patients with incomplete abortion are treated with femoston, and menstrual recovery time may be shortened. Femostons may be a new option for pharmacological treatment of incomplete abortions.

Abstract
PURPOSE/OBJECTIVE(S) A traditional endpoint for locally advanced cervical cancer (LACC) clinical trials is overall survival (OS) with five years of follow-up. At present, many clinical trials evaluating concurrent chemoradiotherapy combined with immunotherapy for LACC are underway in worldwide. The use of a shorter-term endpoint could significantly speed the translation of research findings into practice. The primary hypothesis was that PFS with three years of follow-up (PFS36) is an appropriate primary endpoint to replace OS with five years of follow-up (5-year OS). MATERIALS/METHODS The primary hypothesis was developed from our individual data, was further investigated using phase III randomized controlled trials (RCTs), and then externally validated by phase II trials and retrospective studies up to 2022. Correlation analysis at the treatment-arm level was performed between 2-, 3-, 4-, and 5-year PFS rates and 5-year OS, using the Pearson correlation coefficient r in weighted linear regression, with weight equal to patient size. The MEDLINE, Embase, and PubMed databases, together with the Cochrane Central Register of Controlled Trials, were searched from January 1, 1999, to February 2, 2023. Articles eligible for inclusion contained complete survival data. RESULTS A total of 613 patients with histologically confirmed, FIGO 2009 stage IB-IVA cervical cancer who underwent radiotherapy at our institute from January 2010 to December 2013 were eligible. Individual patient data were pooled to explore the correlation between PFS and the OS trend. The recurrence rates for years 1 through 5 were 12.9%, 7.3%, 3%, 2.3%, and 1.8%, respectively. The median recurrence time was 13 months and the median time from recurrence to death was 12.2 months. Within all the recurrence, 47.3% of recurrences occurred during the first year, 71.4% in the first two years, and 85% in the first three years. Patients who did not achieve PFS36 had a 5-year OS rate of 30.3%. In contrast, a 5-year OS rate of 98.2% was observed in patients who achieved PFS36. Further data were extracted from 27 RCTs on locally advanced cervical cancer. The trials included 57 arms, with a pooled sample size of 7,692 patients. Formal measures of surrogacy were satisfied. Quality control was performed, where studies with a high risk of bias were excluded. In trial-level surrogacy, PFS36 (r2, 0.778) was associated with 5-year OS. The correlation between PFS36 and OS was externally validated using independent phase II trials and retrospective data. In total, 23 studies representing 5,174 patients were included. PFS36 (r2, 0.719) was found to be associated with OS. CONCLUSION The patients who achieved PFS36 had excellent outcomes, whereas patients that experienced earlier progression had poor survival. A significant correlation was found between PFS36 and 5-year OS in clinical trials on patients with locally advanced cervical cancer. These results suggest that PFS36 is an appropriate endpoint for LACC clinical trials of radiotherapy-based regimens.

Abstract
PURPOSE Tumor metastasis significantly impacts the prognosis of non-small cell lung cancer (NSCLC) patients, with lymph node (LN) metastasis being the most common and early form of spread. With the development of adjuvant immunotherapy, increasing attention has been paid to the tumor-draining lymph nodes(TDLN) in early-stage NSCLC, especially tumor-metastatic lymph nodes, which provides poor prognostic information but has potential benefits in adjuvant treatment. METHODS We showed the remodeled immune environment in TDLNs through using TCR-seq to analyse 24 primary lung cancer tissues and 134 LNs from 24 lung cancer patients with or without LN metastasis. Additionally, we characterized the spatial profiling of immunocytes and tumor cells in TDLNs and primary tumor sites through using multi-IHC. RESULTS We found the remodeled immune environment in TDLNs through analyzing primary lung cancer tissues and LNs from NSCLC patients with or without LN metastasis. Considering the intricate communication between tumor and immunocytes, we further subdivided TDLNs, revealing that metastasis-negative LNs from LN-metastatic patients (MNLN) exhibited greater immune activation, exhaustion, and memory in comparison to both metastasis-positive LNs (MPLN) and TDLNs from non-LN-metastatic patients (NMLN). CONCLUSIONS Our data indicate that LN metastasis facilitated tumor-specific antigen presentation in TDLNs and induces T cell priming, while existing tumor cells generate an immune-suppressive environment in MPLNs through multiple mechanisms. These findings contribute to a comprehensive understanding of the immunological mechanisms through which LN metastasis influences tumor progression and plays a role in immunotherapy for NSCLC patients.

Abstract
This study aimed to explore the biological role and mechanism underlying the effects of colon cancer-associated transcript 2 (CCAT2), a long noncoding RNA (lncRNA) in human laryngeal squamous cell carcinoma (LSCC). CCAT2 expression levels in clinical LSCC samples and TU-212 cell line were evaluated by quantitative real-time PCR. The correlation of CCAT2 expression level with clinical-pathological characteristics of patients and their prognosis was analyzed. The functional role of CCAT2 in human LSCC was assessed by Cell Counting Kit-8, Transwell assay, flow cytometric analysis, and LSCC xenograft experiment in vivo. The expression of potential targeted proteins was detected by Western blotting and immunohistochemistry. We found that expression of CCAT2 was significantly elevated in LSCC tissues and TU-212 cells (p<0.05). Survival analysis showed that LSCC patients with high expression of CCAT2 had a shorter 5-year overall survival rate than those with low expression (p<0.05). In addition, CCAT2 silencing with short hairpin RNA significantly decreased the proliferative and invasive potential of TU-212 cells (p<0.05) and promoted their apoptosis. In Nude mice, CCAT2 knockdown suppressed the growth of tumor and decreased its volume and weight in comparison with the controls (p<0.05). In TU-212 cells, CCAT2 silencing with short hairpin RNA significantly down-regulated the expression of β-catenin and CDK8 (p<0.05). Thus, knockdown of CCAT2 suppresses proliferation and invasion of the cells and inhibits Wnt/β-catenin signaling pathway in LSCC, which indicates novel therapeutic targets and prognostic indicators in patients with LSCC.

Abstract
In recent years, as a class of advanced additive manufacturing (AM) technology, photocurable 3D printing has gained increasing attention. Based on its outstanding printing efficiency and molding accuracy, it is employed in various fields, such as industrial manufacturing, biomedical, soft robotics, electronic sensors. Photocurable 3D printing is a molding technology based on the principle of area-selective curing of photopolymerization reaction. At present, the main printing material suitable for this technology is the photosensitive resin, a composite mixture consisting of a photosensitive prepolymer, reactive monomer, photoinitiator, and other additives. As the technique research deepens and its application gets more developed, the design of printing materials suitable for different applications is becoming the hotspot. Specifically, these materials not only can be photocured but also have excellent properties, such as elasticity, tear resistance, fatigue resistance. Photosensitive polyurethanes can endow photocured resin with desirable performance due to their unique molecular structure including the inherent alternating soft and hard segments, and microphase separation. For this reason, this review summarizes and comments on the research and application progress of photocurable 3D printing of photosensitive polyurethanes, analyzing the advantages and shortcomings of this technology, also offering an outlook on this rapid development direction.

Abstract
Currently, increasing attention is being paid to biomarkers in endometrial cancer. Immune infiltration of the tumor microenvironment has been shown to significantly affect the overall survival (OS) of uterine corpus endometrial carcinoma (UCEC) patients. LINC01589 is a long non-coding RNA (lncRNA) that is rarely reported in cancer and is assumed to play a role in immune regulation. We therefore evaluated the role of LINC01589 in UCEC using the Cancer Genome Atlas (TCGA) database. We analyzed the expression of LINC01589 using the gene expression profiles of LINC01589 in the UCEC projects in TCGA. Comparisons between the differentially expressed genes (DEGs) of the cancer and adjacent normal tissues of the UCEC projects revealed that LINC01589 expression was decreased in UCEC tissues. A multivariate cox regression analysis indicated that LINC01589 upregulation could serve as an independent prognostic factor for survival. Furthermore, there was a positive correlation between LINC01589 expression and B cell, T cell, NK cell, monocytic lineage, and myeloid dendritic cell infiltration in UCEC patients. In addition, 5 clusters of hub genes were detected by comparison of different expression levels of LINC01589 in the UCEC groups. The analysis of the reactome pathway using gene set enrichment analysis (GSEA) revealed immune-related pathways, including CD22-mediated B cell receptor (BCR) regulation and antigen-activated BCRs, leading to the generation of second messengers and complement cascade pathways that were significantly enriched in the high LINC01589 expression group. Thus, LINC01589 may serve as a prognostic biomarker, as it is associated with immune infiltration in UCEC.

Abstract
OBJECTIVES To evaluate the clinical efficacy of thermocoagulation in women with biopsy-confirmed cervical low-grade squamous intraepithelial lesions (LSIL) or less after colposcopy referral. MATERIAL AND METHODS A longitudinal study was performed. Women who were diagnosed with cervical LSIL or chronic cervicitis underwent scheduled follow-up examinations with cytology and human papilloma virus (HPV) genotyping for two years after the initial management with thermocoagulation or observation without treatment. All women underwent scheduled follow-up with combined cytology and HPV test at 6th months, 12th months, and 24th months after the initial management. Both HPV clearance and cytological regression were included in the analysis, with clinical cure defined as normal cytology and negative HPV results. RESULTS A total of 221 women were included. The histopathological results identified 136 (61.54%) patients with LSIL and 85 (38.46%) with chronic cervicitis. Of these, 113 (51.13%) received thermocoagulation therapy, and 108 (48.87%) chose observation. The 2-year follow-up rate was 91.40%. Women who received thermocoagulation presented a significantly higher probability of cure for two years than those who chose observation (62.86% vs 39.18%, p < 0.001). This preponderance was not observed in the subgroup analysis regarding women with cervical cervicitis (54.17% vs 41.38%, p = 0.277) but was observed in women with LSILs (70.18% vs 38.24%, p < 0.001). CONCLUSIONS Thermocoagulation may be indicated for patients with cervical LSILs as an effective outpatient procedure in clinical practice.

Abstract
INTRODUCTION This study aims to compare the safety and efficacy of bivalirudin bridging enoxaparin versus fondaparinux in patients with acute myocardial infarction (AMI) who were undergoing primary percutaneous coronary intervention (PPCI). METHODS The study is a prospective, natural, and selective interventional trial based on real-world data for 482 AMI patients. RESULTS At the end of the follow-up, the two groups demonstrated similar major adverse cardiovascular and cerebrovascular events (MACCE) and bleeding rates. After propensity score matching (PSM), the fondaparinux group showed greater advantages in reducing MACCE and bleeding events. CONCLUSIONS The anticoagulation strategy of bivalirudin bridging fondaparinux seems to be superior to that of bivalirudin bridging enoxaparin in patients with AMI undergoing PPCI.

Abstract
Rhodobacter probiotics are considered as good alternatives to antibiotics for aquaculture. Yet the beneficial effects of Rhodobacter on Chinese mitten crab Eriocheir sinensis are still unclear, and more functions of Rhodobacter supplementation need to be clarified. In this study, a 60-day feeding trial was performed to investigate the protective effects of R. azotoformans against citrobacteriosis in E. sinensis by growth performance, serum immunity, hepatopancreatic antioxidant capability, intestinal flora, and resistance to Citrobacter freundii challenge assays. The results showed that R. azotoformans supplementation significantly and dose-dependently increased weight gain and specific growth rate as well as activities of serum immune and hepatopancreatic antioxidant enzymes, leading to notable improvement in the growth performance, serum immunity and hepatopancreatic antioxidant status of E. sinensis. Besides, R. azotoformans supplementation significantly enhanced intestinal microbial abundance and diversity in E. sinensis, and conferred significant protection of the crabs against C. freundii challenge with seven-day survival rates of 70.0%-100.0%. To the best of our knowledge, this is the first study to reveal the protective effects of R. azotoformans against citrobacteriosis in E. sinensis.

Abstract
As one of the most valuable endogenous gas signaling molecules, carbon monoxide (CO) has been demonstrated in numerous studies to show excellent promise in the treatment of diseases, such as cancer. However, for many years, the inherent high affinity of CO for hemoglobin severely impeded the clinical transformation of CO-based treatments. Therefore, the controlled delivery of CO to target tissues has become a common challenge. Herein, an efficient ultrasonic-triggered and targeted CO release strategy was constructed based on a novel targeted acoustic release carrier of carbon monoxide (TARC-CO) that we synthesized in this study. The designed TARC-COs could afford a safe, stable, and ultrasound-guided delivery of CO in vivo by loading a specified dose of CO inside microbubbles, resulting in breast tumor suppression. Taking advantage of the high loading capacity of microbubbles, the unit volume of TARC-CO suspension could encapsulate up to 337.1 ± 8.0 (×103 ppm) of CO. In addition, the satisfactory ultrasound contrast-enhanced ability of TARC-COs achieved real-time interactive guidance and visual policing of CO delivery. For the in vitro antitumor study, TARC-COs with ultrasonic irradiation were demonstrated to effectively induce mitochondrial dysfunction by reducing mitochondrial membrane potential, leading to the apoptosis of 4T1 cells. In addition, we realized that TARC-CO-based treatment could significantly slow the growth rate of tumors by inducing apoptosis, inhibiting the proliferation of cancer cells, and limiting tumor angiogenesis. In summary, this proof-of-concept study demonstrates the feasibility and tremendous potential of TARC-COs for controlled release of CO, which can be expected to provide new inspirations and a promising perspective for therapy based on active gases.

Abstract
Abstract
Objective
Administration of GnRH agonist (GnRHa) prior to chemotherapy may decreases the risk of gonadal dysfunction in patients with tumors. However, relevant data in haematopoietic stem cell transplantation (HSCT) recipients has not yet been established. Hence, the present study was designed to evaluate the clinical efficacy of GnRHa cotreatment prior to myeloablative regimens on ovarian protection in female survivors of HSCT for haematological diseases.
Patients and methods
Eligible patients were divided into a GnRHa group and a control group. Medical records regarding age at HSCT; diagnosis/indication for HSCT; pre- and posttransplantation serum sex hormone levels; menstruation and perimenopausal symptoms after HSCT were collected and compared. The primary and secondary outcome was the incidence of premature ovarian insufficiency (POI) symptoms associated with hypoestrogenism.
Results
A total of 330 patients were enrolled in the study: 19 patients were lost to follow-up, and clinical information was obtained in 311 patients. There was no significant difference in the primary outcome of follow-up between the two groups (78.50% [84 of 107] for the GnRHa group versus 83.33% [170 of 204] for the control group). The adjusted relative risks (RR) and 95% confidence interval (CI) were 1.19 and 0.73–1.93 (P = 0.487). Among patients who received cotreatment with GnRHa, 62.62% (67 of 107) complained of perimenopausal symptoms, which was significantly lower than the 74.51% (152 of 204) in the control group (adjusted RR: 1.46, 95% CI: 1.04–2.06, P = 0.031).
Conclusion
GnRHa cotreatment may not decrease the POI rate in HSCT survivors. However, it may reduce perimenopausal symptoms in this population, suggesting a potential benefit of GnRHa in clinical practice and warrant further researches.

Abstract
Video summarization (VS) is a widely used technique for facilitating the effective reading, fast comprehension, and effective retrieval of video content. Certain properties of the new video data, such as a lack of prominent emphasis and a fuzzy theme development border, disturb the original thinking mode based on video feature information. Moreover, it introduces new challenges to the extraction of video depth and breadth features. In addition, the diversity of user requirements creates additional complications for more accurate keyframe screening issues. To overcome these challenges, this paper proposes a hierarchical spatial-temporal cross-attention scheme for video summarization based on comparative learning. Graph attention networks (GAT) and the multi-head convolutional attention cell are used to extract local and depth features, while the GAT-adjusted bidirection ConvLSTM (DB-ConvLSTM) is used to extract global and breadth features. Furthermore, a spatial-temporal cross-attention-based ConvLSTM is developed for merging hierarchical characteristics and achieving more accurate screening in similar keyframes clusters. Verification experiments and comparative analysis demonstrate that our method outperforms state-of-the-art methods.

Abstract
The application of drug-loaded nanodroplets is still limited by their insufficient accumulation owing to the enhanced permeability and retention (EPR) effect failure in cancer therapy. To overcome these limitations, we propose an alternative magnetic particle-encapsulated nanodroplet (MPE-ND) with outstanding biosafety and magnetic targeting by encapsulating fluorinated Fe3O4-SiO2 nanoparticles inside the liquid core of the nanodroplets. Meanwhile, doxorubicin (DOX) can be stably loaded into the shell through both electrostatic and hydrophobic interactions to obtain drug-loaded MPE-NDs. Both in vitro and in vivo experiments have consistently demonstrated that drug-loaded MPE-NDs can significantly increase the local drug concentration and enhance the damage of tumor tissues through acoustic droplet vaporization under a static magnetic field (eADV therapy). Histological examination reveals that eADV therapy efficiently suppresses tumor proliferation by inducing apoptosis, destroying supply vessels, and inhibiting neovascularization. Drug-loaded MPE-NDs can be expected to open a new gateway for ultrasound-triggered drug delivery and cancer treatment.

Abstract
This study aimed to evaluate clinical predictors associated with complete miscarriage after medical treatment for early pregnancy loss (EPL) in women with previous cesarean section. Patients with retained uterine content after expulsion followed by administration of mifepristone and misoprostol were included if they chose continued medical treatment rather than surgical intervention. Clinical characteristics including maternal age, gravidity, parity, history of previous cesarean section and ultrasound findings regarding average diameter of the gestational sac, uterine position, width, and blood flow signal of the residual uterine content after expulsion of the gestational sac were included in the analysis to determine predictors of complete miscarriage. A recursive partitioning analysis (RPA) was used to divide the patients into probability groups and assess their probability of complete miscarriage. A total of 89 patients were analyzed. The complete miscarriage rate was 58.43% overall. Multivariable logistic regression analysis showed that the width and blood flow signal of the residual after expulsion were both independent predictors for complete miscarriage (all P < .05). Patients were divided into high-probability (no blood flow signal, width of residual <1 cm), intermediate-probability (no blood flow signal, width of residual ≥1 cm; blood flow signal, width of residual <1 cm), and low-probability (blood flow signal, width of residual ≥ 1 cm) groups by RPA according to these 2 factors. The incidences of complete miscarriage were 88.24%, 67.57%, and 34.29%, respectively, P < .001). Surgical evacuation may be avoided in patients without ultrasonic blood flow of the uterine residual and width of the residual <1 cm. More active treatment could be recommended for patients with ultrasonic blood flow of the uterine residual and width of the residual ≥ 1 cm. Clinicians and patients should be aware of these differences when proceeding with medical treatment for EPL patients with previous cesarean section.

Abstract
BACKGROUND Atrial fibrillation (AF) is one of the most common arrhythmias, and radiofrequency catheter ablation is the most effective treatment strategy. The inferior vena cava (IVC) is a common approach for radiofrequency ablation of AF. However, this approach may not be applied to some cases such as chronic venous occlusions, surgical ligation of the IVC, and heterotaxy syndrome (HS).
CASE SUMMARY A 68-year-old man with HS suffered from severely symptomatic persistent AF for 9 years, and we successfully ablated by percutaneous transhepatic access.
CONCLUSION In patients without femoral vein access, the use of the hepatic vein for pulmonary vein isolation is a viable alternative for invasive electrophysiology procedures.

Abstract
Diabetes mellitus (DM) is accompanied by a series of macrovascular and microvascular injuries. Critical limb ischemia is the most severe manifestation of peripheral artery disease (PAD) caused by DM and is almost incurable. Therapeutic modulation of angiogenesis holds promise for the prevention of limb ischemia in diabetic patients with PAD. However, no small-molecule drugs are capable of promoting diabetic angiogenesis. An endogenous tryptophan metabolite, indole-3-aldehyde (3-IAld), has been found to have proangiogenic activity in endothelial cells. Nevertheless, the role of 3-IAld in diabetic angiogenesis remains unknown. Here, we found that 3-IAld ameliorated high glucose-induced mitochondrial dysfunction, decreasing oxidative stress and apoptosis and thus improving neovascularization.

Abstract
PURPOSE Ketone body oxidation yields more ATP per mole of consumed oxygen than glucose. However, whether an increased ketone body supply in hypoxic cardiomyocytes and ischemic hearts is protective or not remains elusive. The goal of this study is to determine the effect of β-hydroxybutyrate (β-OHB), the main constituent of ketone bodies, on cardiomyocytes under hypoxic conditions and the effects of ketogenic diet (KD) on cardiac function in a myocardial infarction (MI) mouse model. METHODS Human peripheral blood collected from patients with acute myocardial infarction and healthy volunteers was used to detect the level of β-OHB. N-terminal proB-type natriuretic peptide (NT-proBNP) levels and left ventricular ejection fractions (LVEFs) were measured to study the relationship between plasma β-OHB and cardiac function. Adult mouse cardiomyocytes and MI mouse models fed a KD were used to research the effect of β-OHB on cardiac damage. qPCR, western blot analysis, and immunofluorescence were used to detect the interaction between β-OHB and glycolysis. Live/dead cell staining and imaging, lactate dehydrogenase, Cell Counting Kit-8 assays, echocardiography, and 2,3,5-triphenyltetrazolium chloride staining were performed to evaluate the cardiomyocyte death, cardiac function, and infarct sizes. RESULTS β-OHB level was significantly higher in acute MI patients and MI mice. Treatment with β-OHB exacerbated cardiomyocyte death and decreased glucose absorption and glycolysis under hypoxic conditions. These effects were partially ameliorated by inhibiting hypoxia-inducible factor 1α (HIF-1α) degradation via roxadustat administration in hypoxia-stimulated cardiomyocytes. Furthermore, β-OHB metabolisms were obscured in cardiomyocytes under hypoxic conditions. Additionally, MI mice fed a KD exhibited exacerbated cardiac dysfunction compared with control chow diet (CD)-fed MI mice. CONCLUSION Elevated β-OHB levels may be maladaptive to the heart under hypoxic/ischemic conditions. Administration of roxadustat can partially reverse these harmful effects by stabilizing HIF-1α and inducing a metabolic shift toward glycolysis for energy production.

Abstract
BackgroundSystemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by over-activity of lymphocytes, production of autoantibodies and effects on multiple organs 1. Growing evidences suggest long noncoding RNAs (lncRNAs) and mRNAs widely participate in physiological and pathological processes. However, knowledge of related lncRNAs and mRNAs in SLE remains limited.ObjectivesThe aim of our study is to investigate the levels of differential expression of lncRNAs and mRNAs in the peripheral blood mononuclear cells (PBMCs) of SLE patients and their correlation with disease activity, clinical features and cell differentiation.MethodsPeripheral venous blood 4ml were collected from 11 patients with SLE before and after treatment and 11 sex-and age-matched healthy individuals and saved in EDTA tubes. PBMCs were isolated from peripheral blood samples by Ficoll-Histopaque density gradient centrifugation. Total RNA was extracted from PBMCs with TRIzol reagent. RNAs amount and quality were quantified by using a NanoDrop ND-1000. Peripheral blood samples were sent to Novogene Co. Ltd (Beijing, China) for sequencing. The DESeq package in R language was used to analyze the differential expression of lncRNAs and mRNAs in the two groups. GO and KEGG databases analyze the potential biological functions and signal transduction and disease pathways affected by abnormal expression of lncRNAs and mRNAs2.ResultsAccording to the RNAs expression profiles, 338 lncRNAs (173 upregulated and 165 downregulated) and 2020 mRNAs (1292 upregulated and 728 downregulated) were differentially expressed between SLE patients and control groups. In addition, 17 lncRNAs were significantly downregulated and 66 mRNAs (47 upregulated and 19 downregulated) were differentially expressed between active and treated SLE patients. There were 1645 RNAs up-expression in active SLE patients and 36 RNAs under-expression in treated SLE patients, and total 14 RNAs changed direction of expression. GO and KEGG pathway analysis showed most of mRNAs were related to transcription, inflammation and immunity. The relativity between aberrantly expressed RNAs and clinical characteristics of active and treated SLE patients were shown in Table 1.ConclusionDysregulation of lncRNAs and mRNAs involves in molecular regulation of SLE, which may support for diagnosis or determination of the susceptibility of individuals of SLE.References[1]Tsokos GC.

Abstract
Background Anlotinib as a third‐line or beyond therapy for extensive‐stage small‐cell lung cancer (ES‐SCLC) was studied. This single‐arm phase II trial was to investigate the value of anlotinib plus platinum‐etoposide as first‐line treatment in ES SCLC. Methods The primary endpoint was progression‐free survival (PFS) and objective response rate (ORR). The secondary endpoints included overall survival (OS), disease control rate (DCR), time to progression (TTP), duration of remission (DoR), and safety. The subgroups of preset liver metastasis and brain metastasis were analyzed. Results In 35 ES‐SCLC patients, the median PFS, ORR, DCR, and OS were 8.02 months [95% confidence interval (CI): 6.90–9.66], 85.71% (95% CI: 69.74–95.19), 94.29% (95% CI: 80.84–99.30), and 15.87 months (95% CI: 10.38–18.89), respectively. The median PFS in the liver metastasis and brain metastasis subgroups was 7.33 months (95% CI: 4.76–9.69) and 7.34 months (95% CI: 5.68–9.20), respectively. The most common AEs with grade 3–4 were hand–foot syndrome (17%), granulocytosis (17%), stomatitis (14%), hypertriglyceridemia (11%), hypercholesterolemia (11%), as well as nausea and vomiting (11%), and no grade 5 AEs were recorded. Conclusions Anlotinib combined with platinum‐etoposide provided an effective and safe therapy for patients with ES‐SCLC.

Abstract
Biomedical imaging technology (like digital subtraction angiography (DSA)) based on contrast agents has been widely employed in the diagnosis of vascular-related diseases. While the DSA achieves the high-resolution observation of specified vessels and their downstream perfusion at the cost of invasive, radioactive operation and hepatorenal toxicity. To address those problems, this study develops arterial labeling ultrasound (US) subtraction angiography (ALUSA) based on a new perfluorobutane (PFB) nanodroplets with a lower vaporization threshold through spontaneous nucleation. The nanodroplets can be selectively vaporized to microbubbles, indicating a highly echogenic signal at B-mode images only using a diagnostic transducer. By labeling a single blood vessel for nanodroplets vaporization and tracking its downstream blood perfusion in segmental renal arteries at a frame rate of 500 Hz. The results demonstrate the color-coded super-resolution ALUSA image, exhibiting the downstream arcuate and interlobular arteries of each segmental renal artery with a resolution of 36 µm in a rabbit kidney. Furthermore, ALUSA could offer the vascular structures, blood flow velocity, and direction of their primary supply vessels in the mouse breast tumor. ALUSA fills the gap of noninvasive labeling angiography in US and opens a broad vista in the diagnosis and treatment of tumor and vascular-related diseases.

Abstract
Submucosal uterine fibroids are usually associated with infertility and miscarriage. Hence, term pregnancies with large submucosal fibroids are rare in clinical practice. The management of fibroids during pregnancy remains controversial. We, herein, describe a case of natural conception, complicated with a massive submucosal fibroid in a 29-year primigravida. The pregnancy was uneventful with satisfactory fetal growth on serial ultrasound scans until the 41st week of gestation. At the time of caesarean section, we performed myomectomy successfully after bilateral uterine artery ligation. There was no blood transfused perioperatively. The patient achieved a satisfactory recovery and was discharged on day-4 after surgery. This case indicates that myomectomy during caesarean section may be a safe and feasible intervention in carefully selected cases of submucosal fibroids. Key Words: Myomectomy, Submucosal fibroid, Pregnancy, Caesarean section.

Abstract
BACKGROUND AND PURPOSE Conventionally, early treatment response to stereotactic radiotherapy in intracranial tumors is often determined by structural MR imaging. Tissue sodium concentration is altered by cellular integrity and energy status in cells. In this study, we aimed to investigate the feasibility of sodium MR imaging at 7T for the preliminary evaluation of radiotherapeutic efficacy for intracranial tumors. MATERIALS AND METHODS Data were collected from 16 patients (12 men and 4 women, 24-75 years of age) with 22 intracranial tumors who were treated with stereotactic radiation therapy using CyberKnife at our institution between December 1, 2016, and August 15, 2019. Sodium MR imaging was performed at 7T before and 48 hours, 1 week, and 1 month after CyberKnife radiation therapy. Tissue sodium concentration (TSC) was calculated and analyzed based on manually labeled regions of tumors. RESULTS Ultra-high-field sodium MR imaging clearly showed the intratumoral signal, which is significantly higher than that of normal tissue (t = 5.250, P <.001)., but the edema zone has some influence. The average TSC ratios of tumor to CSF in the 22 tumors, contralateral normal tissues, edema zones, frontal cortex, and frontal white matter were 0.66 (range, 0.23-1.5), 0.30 (range, 0.15-0.43), 0.58 (range, 0.25-1.21), 0.25 (range, 0.17-0.42), and 0.30 (range, 0.19-0.49), respectively. A total of 12 tumors in 8 patients were scanned at 48 hours, 1 week, and 1 month after treatment. The average TSC at 48 hours after treatment was 0.06 higher than that before treatment and began to decrease at 1 week. The TSC ratios of 10 continued to decline and 2 tumors increased at 1 month, respectively. Tumor volume decreased by 2.4%-99% after 3 months. CONCLUSIONS Changes in the TSC can be quantified by sodium MR imaging at 7T and used to detect radiobiologic alterations in intracranial tumors at early time points after CyberKnife radiation therapy.

Abstract
Lung cancer is one of the most lethal malignant tumors in the world. The high recurrence and mortality rate make it urgent for scientists and clinicians to find new targets for better treatment of lung cancer. Early studies indicated that estrogen receptor β (ERβ) might impact the progression of non-small-cell lung cancer (NSCLC). However, the detailed mechanisms, especially its linkage to the CXCR4-mediated cell invasion, remain unclear. Here we found that ERβ could promote NSCLC cell invasion via increasing the circular RNA (circRNA), circ-TMX4, expression via directly binding to the 5′ promoter region of its host gene TMX4. ERβ-promoted circ-TMX4 could then sponge and inhibit the micro RNA (miRNA, miR), miR-622, expression, which can then result in increasing the CXCR4 messenger RNA translation via a reduced miRNA binding to its 3′ untranslated region (3′UTR). The preclinical study using an in vivo mouse model with orthotopic xenografts of NSCLC cells confirmed the in vitro data, and the human NSCLC database analysis and tissue staining also confirmed the linkage of ERβ/miR-622/CXCR4 signaling to the NSCLC progression. Together, our findings suggest that ERβ can promote NSCLC cell invasion via altering the ERβ/circ-TMX4/miR-622/CXCR4 signaling, and targeting this newly circ-TMX4/miR-622/CXCR4 signaling may help us find new treatment strategies to better suppress NSCLC progression.

Abstract
Objective: This study was aimed at investigating the effects of preoperative treatment with a loading dose of statinscombined with a PCSK9 inhibitor on coronary blood perfusion and short-term cardiovascular adverse events in patientswith ST-segment elevation myocardial infarction (STEMI).Method: Sixty-five patients with STEMI who had visited the Shanxi Cardiovascular Disease Hospital between May2018 and May 2021 were enrolled in the study. The enrolled patients had no history of oral statins or antiplatelet therapy.The patients were divided into a combined treatment group (loading dose of statins combined with PCSK9 inhibitors, 35patients) and a routine treatment group (loading dose of statins only, 30 patients). The primary endpoints were thrombolysisin myocardial infarction (TIMI) blood flow grading, corrected TIMI frame count (CTFC), and TIMI myocardial perfusiongrading (TMPG), immediately after and 30 days after the operation. The secondary endpoint was a composite endpoint ofcardiovascular death, nonfatal myocardial infarction, and target vessel revascularization 30 days after the operation.Results: The combined treatment group had significantly lower CTFC (14.09 ± 8.42 vs 26 ± 12.42, P = 0.04) and betterTMPG (2.74 ± 0.61 vs 2.5 ± 0.73, P = 0.04) than the routine treatment group immediately after the operation. Similarly,the combined treatment group had a significantly lower CTFC (16.29 ± 7.39 vs 26.23 ± 11.53, P = 0.04) and significantlybetter TMPG (2.94 ± 0.24 vs 2.76 ± 0.43, P = 0.01) than the routine treatment group 1 month after the operation.Conclusion: Preoperative treatment with a loading dose of high-intensity statins combined with PCSK9 inhibitorsincreased coronary blood flow and myocardial perfusion after emergency thrombus aspiration in patients withSTEMI. However, the treatment did not significantly decrease the incidence of cardiovascular death, nonfatal myocardialinfarction, or target vessel revascularization.

Abstract
Objective: To investigate the safety and efficacy of retroperitoneal laparoscopic selective renal artery branch occlusion with nephron sparing surgery in patients with renal carcinoma of stage ≥ T1b. Methods: From July 2016 to September 2020, 35 patients with renal cancer ≥T1b underwent retroperitoneoscopic nephron sparing surgery in the First Affiliated Hospital of Shenzhen University. The surgical methods were retroperitoneoscopic nephron sparing surgery with total renal artery occlusion (group A) or selective renal artery branch occlusion (group B). Operation time, heat ischemia time, blood transfusion rate, positive margin rate, intraoperative blood loss, postoperative complications and length of hospital stay were compared between the two groups, and the total glomerular filtration rate (GFR) and the single-nephron glomerular filtration rate (sGFR) of the offected kidneys were compared between the two groups before, 3 months after and 12 months after surgery. Results: Among the 35 patients, 19 were male and 16 were female, aged (55.7±8.4) years and the body mass index is (24.6±3.1) kg/m2. The tumor diameter was (54.7±10.3) mm. The difference was statistically significant of operative time between group A and B [(103.5±14.3) vs (123.2±14.1) min,P=0.003]. There were no significant differences in thermal ischemia time, blood transfusion rate, positive margin, intraoperative blood loss, incidence of postoperative complications and length of hospital stay between the two groups (all P>0.05). The decrease of renal sGFR in the group A was significantly higher than group B at 3 months and 12 months after surgery [(23.1±3.6) vs (29.1±7.1) ml/min;(25.9±4.7) vs (30.7±7.2),both P<0.05]. Conclusion: Retroperitoneal laparoscopic selective renal artery branch occlusion and neon-sparing surgery for patients with ≥ T1b stage renal carcinoma is a safe and effective surgical method, which can well protect the renal function of patients in the early postoperative stage without increasing intraoperative blood loss and postoperative complications.

Here we show a dengue epidemic in Yunnan, China, during the pandemic of COVID-19 was dramatically reduced compared to non-pandemic years and, importantly, spread was confined to only one city, Ruili. Three key features characterized this dengue outbreak: (i) the urban-to-suburban spread was efficiently blocked; (ii) the scale of epidemic in urban region was less affected; (iii) co-circulation of multiple strains was attenuated. These results suggested that countermeasures taken during COVID-19 pandemic are efficient to prevent dengue transmission between cities and from urban to suburban, as well to reduce the co-circulation of multiple serotypes or genotypes. Nevertheless, as revealed by the spatial analysis, once the dengue outbreak was established, its distribution was very stable and resistant to measures against COVID-19, implying the possibility to develop a precise prediction method.

Abstract
Objective:Microvasculature is highly relevant to the occurrence and development of pathologies such as cancer and diabetes. Ultrasound localization microscopy (ULM) has bypassed the diffraction limit and demonstrated its great potential to provide new imaging modality and establish new diagnostic criteria in clinical application. However, sparse microbubble distribution can be a significant bottleneck for improving temporal resolution, even for further clinical translation. Other important challenges for ULM to tackle in clinic also include high microbubble concentration and low frame rate.Approach:As part of the efforts to facilitate clinical translation, this paper focused on the low frame rate and the high microbubble distribution issue and proposed a new super-resolution imaging strategy called entropy-based radiality super-resolution (ERSR). The feasibility of ERSR is validated with simulations, phantom experiment and contrast-enhanced ultrasound scan of rabbit sciatic nerve with clinical accessible ultrasound system.Main results:ERSR can achieve 10 times improvement in spatial resolution compared to conventional ultrasound imaging, higher temporal resolution (∼10 times higher) and contrast-to-noise ratio under high-density microbubbles, compared with ULM under low-density microbubbles.Significance:We conclude ERSR could be a valuable imaging tool with high spatio-temporal resolution for clinical diagnosis and assessment of diseases potentially.

Abstract
The advent of localization-based super-resolution ultrasound (SRUS) imaging creates a vista for precision vasculature and hemodynamic measurements in brain science, cardiovascular diseases, and cancer. As blinking fluorophores are crucial to super-resolution optical imaging, blinking acoustic contrast agents enabling ultrasound localization microscopy have been highly sought, but only with limited success. Here we report on the discovery and characterization of a type of blinking acoustic nanodroplets (BANDs) ideal for SRUS. BANDs of 200-500 nm diameters comprise a perfluorocarbon-filled core and a shell of DSPC, Pluronic F68, and DSPE-PEG2000. When driven by clinically safe acoustic pulses (MI < 1.9) provided by a diagnostic ultrasound transducer, BANDs underwent reversible vaporization and reliquefaction, manifesting as "blinks", at rates of up to 5 kHz. By sparse activation of perfluorohexane-filled BANDs-C6 at high concentrations, only 100 frames of ultrasound imaging were sufficient to reconstruct super-resolution images of a no-flow tube through either cumulative localization or temporal radiality autocorrelation. Furthermore, the use of high-density BANDs-C6-4 (1 × 108/mL) with a 1:9 admixture of perfluorohexane and perfluorobutane supported the fast SRUS imaging of muscle vasculature in live animals, at 64 μm resolution requiring only 100 frames per layer. We anticipate that the BANDs developed here will greatly boost the application of SRUS in both basic science and clinical settings.

Abstract
Introduction Epidermal growth factor receptor (EGFR) 19del and L858R mutation are known as “common mutations” in non-small cell lung cancer (NSCLC) and predict sensitivities to EGFR tyrosine kinase inhibitors (TKIs), whereas 20ins and T790M mutations confer drug-resistance to EGFR-TKIs. The role of the remaining uncommon EGFR mutations remains elusive. Methods We retrospectively screened a group of NSCLC patients with uncommon EGFR mutations other than 20ins and T790M. The mutation patterns, use of different generations of EGFR-TKIs, and concurrent genetic alterations were analyzed. Meanwhile, a cohort of patients with single 19del or L858R were included for comparison. Results A total of 180/1,300 (13.8%) patients were identified. There were 102 patients with advanced or recurrent NSCLC that received first-line therapy of gefitinib/erlotinib/icotinib and afatinib and were eligible for analysis. The therapeutic outcomes among patients with common mutations (EGFRcm, n = 97), uncommon mutation plus common mutations (EGFRum+EGFRcm, n = 52), complex uncommon mutations (complex EGFRum, n = 22), and single uncommon mutations (single EGFRum, n = 28) were significantly different (ORRs: 76.3%, 61.5%, 54.5%, and 50.0%, respectively, p = 0.023; and mPFS: 13.3, 14.7, 8.1, and 6.0 months, respectively, p = 0.004). Afatinib showed superior efficacy over gefitinib/erlotinib/icotinib in EGFRcm (ORR: 81.0% vs. 75.0%, p = 0.773; mPFS: 19.1 vs. 12.0m, p = 0.036), EGFRum+EGFRcm (ORR: 100% vs. 54.5%, p = 0.017; mPFS: NE vs. 13.6m, p = 0.032), and single EGFRum (ORR: 78.6% vs. 21.4%, p = 0.007; mPFS: 10.1 vs. 3.0m, p = 0.025) groups. Comprehensive genomic profiling by Next Generation Sequencing encompassing multiple cancer-related genes was performed on 51/102 patients; the mPFS of patients without co-mutation (n = 16) and with co-mutations of tumor-suppressor genes (n = 31) and driver oncogenes (n = 4) were 31.1, 9.2, and 12.4 months, respectively (p = 0.046). TP53 mutation was the most common co-alteration and showed significantly shorter mPFS than TP53 wild-type patients (7.0 vs. 31.1m, p < 0.001). Multivariate analysis revealed that concurrent 19del/L858R and tumor-suppressor gene alterations independently predicted better and worse prognosis in patients with uncommon mutations, respectively. Conclusions Uncommon EGFR mutations constitute a highly heterogeneous subgroup of NSCLC that confer different sensitivities to EGFR-TKIs with regard to the mutation patterns. Afatinib may be a better choice for most uncommon EGFR mutations. Concurrent 19del/L858R and tumor-suppressor gene alterations, especially TP53, can be established as prognostic biomarkers.

Abstract
Background: Although multiple metabolic pathways are involved in the initiation, progression, and therapy of lung adenocarcinoma (LUAD), the tumor microenvironment (TME) for immune cell infiltration that is regulated by metabolic enzymes has not yet been characterized. Methods: 517 LUAD samples and 59 non-tumor samples were obtained from The Cancer Genome Atlas (TCGA) database as the training cohort. Kaplan-Meier analysis and Univariate Cox analysis were applied to screen the candidate metabolic enzymes for their role in relation to survival rate in LUAD patients. A prognostic metabolic enzyme signature, termed the metabolic gene risk score (MGRS), was established based on multivariate Cox proportional hazards regression analysis and was verified in an independent test cohort, GSE31210. In addition, we analyzed the immune cell infiltration characteristics in patients grouped by their Risk Score. Furthermore, the prognostic value of these four enzymes was verified in another independent cohort by immunohistochemistry and an optimized model of the metabolic-immune protein risk score (MIPRS) was constructed. Results: The MGRS model comprising 4 genes (TYMS, NME4, LDHA, and SMOX) was developed to classify patients into high-risk and low-risk groups. Patients with a high-risk score had a poor prognosis and exhibited activated carbon and nucleotide metabolism, both of which were associated with changes to TME immune cell infiltration characteristics. In addition, the optimized MIPRS model showed more accurate predictive power in prognosis of LUAD. Conclusion: Our study revealed an integrated metabolic enzyme signature as a reliable prognostic tool to accurately predict the prognosis of LUAD.

Abstract
Background:Rheumatoid arthritis (RA) is a systemic autoimmunity inflammation disease characterized with chronic aggressive arthritis and the presence of abnormal antibodies. Several observations showed that the breakdown of immune tolerance caused by many complex interactions was involved in the development of RA[1]. However, the pathogenesis of RA remained unclear. It has been confirmed that the imbalance of Th17 and Treg cells play a crucial role in destroying immune tolerance [2]. Besides, researches showed that intestinal microbiota can influence host immunity by acting on the immune cells to play pro-inflammatory or anti-inflammatory effect, and in turn immune system can also regulate the microbiota[3, 4]. Thus, a frontier point of view in the field of rheumatism, immune microecology, was proposed, which is a novel concept for the breakdown of immune tolerance. Studies have confirmed that there was an imbalance of intestinal microbiota in patients with RA [4]. But the relationship between the CD4+T subsets cells and intestinal microbiota in RA is unknown.Objectives:We detected and compared the absolute number of CD4+T cells subsets in the peripheral blood and the proportion or abundance of intestinal microbiota in patients with RA and healthy adults, and then analyzed the relationship between them to explore the role of CD4+T cells subsets and intestinal microbiota in the pathogenesis of RA.Methods:We collected the sample of stool and blood from 15 patients with RA hospitalized at the Second Hospital of Shanxi Medical University and 8 age and gender-matched healthy controls(HC). The absolute number of CD4+T cells subsets including Th1, Th2, Th17 and Treg cells were detected by flow cytometry. The 16S rRNA in the stool specimens were sequenced by the Roche/45 high-throughput sequencing platform. We analyzed whether there was correlarion between CD4+T subsets cells and intestinal microbiota.Results:Patients with RA had a higher level of Christensenellaceae and a lower level of Pseudomonadaceae as compared with those of HCs at the family level (p<0.05). And at the genus level, the patients with RA had higher levels of Ruminococcus torques, Christensenellaceae R-7, Ruminiclostridium 9 and Ruminococcus 1 compared with those of HCs (p<0.05) (Figure 1).And the Ruminococcus torques at the genus level was negative correlated with the absolute number of Treg cells (p<0.001) (Figure 2).Conclusion:The results here suggested that there were different proportion or abundance of intestinal microbiota between the patients with RA andHCs. And the changes of intestinal microbiota such as Ruminococcus torques were associated with Treg cells, further indicating that the imbalance of intestinal microbiota in RA can destory the immune tolerance. The above results uncovered that the intestinal microbiota had immunomodulatory function, which may be the upstream mechanism participated in the pathogenesis of RA.References:[1]Weyand CM, Goronzy JJ.

Abstract
Purpose This study aimed to investigate the clinical efficacy of temporary ligation of the bilateral uterine arteries during laparoscopy combined with hysteroscopy in the treatment of caesarean scar pregnancy (CSP). Patients and Methods This study was a retrospective analysis of 83 patients who had initially undergone laparoscopy combined with hysteroscopy for CSP between 2012 and 2018 at Xiamen Women and Children’s Hospital. Patients were assigned to the ligation group or the no ligation group according to whether they underwent temporary ligation of the bilateral uterine arteries. Factors extracted from the database included general preoperative information, surgical indicators (intraoperative blood loss, operation time, and blood transfusion), postoperative recovery indicators (β-hCG on day 3 after surgery, time to β-hCG normalization), and postoperative complications (decrease in menstrual bleeding, alteration in the menstrual cycle) and were compared between the two groups. Results The intraoperative blood loss of patients in the ligation group was significantly less than that of patients in the no ligation group (P=0.027), especially in patients with higher serum β-hCG level (P=0.030). No significant differences in the operation time, blood transfusion, decline ratio of hCG on day 3 after surgery, reduction in haemoglobin and haematocrit value, decrease in menstrual bleeding, or alteration in the menstrual cycle were observed between the two groups (P>0.05). Conclusion For CSP patients, temporary ligation of the bilateral uterine arteries during laparoscopy combined with hysteroscopy achieved better clinical outcomes than laparoscopy combined with hysteroscopy without ligation with respect to intraoperative blood loss. This approach offers effective and safe surgical management for CSP in clinical practice.

Abstract
Background:Systemic lupus erythematosus (SLE) is an autoimmune disease with disturbance of lymphocyte subpopulations1. Growing experimental and clinical evidence suggests that chronic inflammatory response induced by gut microbiome critically contribute to the development of SLE2 3.Objectives:To investigate the characteristics of gut microbiome and the associations between flora and peripheral lymphocyte subpopulations in SLE patients.Methods:A total of 19 SLE patients who fulfilled the 2019 American college of Rheumatology (ACR) and European League Against Rheumatism (EULAR) classification criteria and 16 age- and sex- matched healthy controls (HC) were enrolled in this study. The peripheral T lymphocyte subsets of these participants were assessed by flow cytometry and the gut microbiota were investigated via 16s rRNA. Indicators of disease activity such as erythrocyte sedimentation rate (ESR), complement C3 and C4 were recorded at the same time. Mann-Whitney U test was applied to compare T lymphocyte subsets between SLE patients and HC. Spearman analysis was used for calculating correlation between T subsets and highly expressed differential flora as well as their correlation with disease activity indicators. All P-values reported herein were two-tailed and P-value<0.05 was taken as statistically significant.Results:SLE patients had higher proportions of Th17 cells (P=0.020) and γδT cells (P=0.018) but lower levels of Treg cells (P=0.001), Tfh cells (P=0.018) and Naïve CD4+T cells (P=0.004) (Figure 1a-e). The diversity and relative abundance of intestinal flora in patients with SLE were significantly different from those in HCs. Detailly, the α-diversity was decreased in SLE (P<0.05) (Figure 2a-c). Compared with HC, 11 species of flora were discovered to be distinctly different(P<0.05) (Figure 2d-e). Moreover, there was a significant positive correlation between Treg levels and Ruminococcus2 (P=0.042), Th17 and Megamonas (P=0.009), γδT and Streptococcus (P=0.004) as well as Megamonas (P=0.003), Tfh and Bacteroides (P=0.040). Whereas Th1 levels and Bifidobacterium were negatively correlated in these participants (P=0.005). As for clinical disease measures, there were negative correlations not only between ESR and Treg cells (P=0.031) but also C4 and the amount of Unclassified Ruminococcaceae (P=0.032).Conclusion:Abnormality of T cell subsets, especially the level of Naïve CD4+T, γδT, Tfh, Treg, and Th17 cells contributes to the occurrence and progression of SLE, which may be related to the disturbance of gut microbiota. Therefore it is necessary to attach importance to the alteration of gut microbiota to prevent the outbreak of inflammation and maybe they can be identified as biomarkers predicting disease activity.References:[1]Katsuyama T, Tsokos GC, Moulton VR.

Abstract
BACKGROUND Recent clinical studies have reported that some cytokines are associated with lung cancer prognosis and mortality. However, the relationship between cytokines and clinical outcomes in severe lung cancer patients was unclear. IL-6 as an important cytokine in inflammation, expression level in severe lung cancer patients was unknown. METHODS A cohort of 55 severe lung cancer patients were enrolled retrospectively in this study. The clinical characteristics, including performance status (PS), therapeutic effect, and patients' adverse effects, were recorded. The association of cytokines and the concerned clinical outcomes were assessed by logistic regression analysis. The area under the curve (AUC) was assessed to evaluate the strength of prediction. RESULTS The mean age of the patients was 59.8, and 42 patents were males. Increased IL-6 levels were associated with worse PS. Logistic regression analysis demonstrated that higher IL-6 was associated with an increased risk of progressive disease (PD) (OR =1.03, 95% CI: 1.0-1.06). The area under the ROC curve (AUC) of the model used for predicting PD was 0.821. CONCLUSIONS Increased IL-6 levels are correlated with worse PS and are an essential predictor for PD in severe lung cancer patients. Monitoring the IL-6 level may represent an essential strategy in improving the prognosis of patients with severe lung cancer.

Abstract
Objective: To understanding tobacco dependence and its influencing factors among smokers aged 40 or older in China and provide scientific data for the implementation of smoking cessation intervention. Methods: The data of this study were collected from 125 surveillance sites in 31 provinces (autonomous regions and municipalities) of chronic obstructive pulmonary disease (COPD) surveillance in China (2014 and 2015). The relevant variables of smoking status and tobacco dependence among people aged 40 or older were collected by face-to-face interview. The weighted proportion of tobacco dependence and its 95%CI and influencing factors among current smokers and daily smokers aged 40 or older in China were estimated with complex sampling weights. Results: A total of 22 380 current smokers and 19 999 daily smokers were included in the analysis. The proportion of high tobacco dependence of current smokers aged 40 or older was 31.1% (29.3%-32.9%). The proportion of high tobacco dependence was higher in men than in women, and higher in rural smokers than urban smokers. The proportion was 33.3% (31.3%-35.2%) in 40 to 59 years old smokers, which was higher than older age group. The proportion of high tobacco dependence among daily smokers aged 40 or older was 35.0% (33.0%-37.0%), and was 35.8% (33.8%-37.8%) in men and 22.0% (16.8%-27.2%) in women. Among current smokers and daily smokers, with the decrease of education level, the proportion of high tobacco dependence increased. The proportion of high tobacco dependence of smokers who started smoking before 18 years old was significantly higher than those who started smoking after 18 years old. The ratio of high tobacco dependence of smokers with chronic respiratory symptoms was higher than that of asymptomatic smokers. There was no significant difference in the tobacco dependence between patients with chronic diseases or chronic respiratory diseases and non patients (P>0.05). Smokers with diabetes, cardiovascular and cerebrovascular diseases and hypertension had a slightly lower proportion of high tobacco dependence than smokers without above diseases (P<0.05). Multivariate logistic regression analysis showed that men, central and eastern regions, 40-59 age group, engaged in agriculture, forestry, animal husbandry, fishery industry, water conservancy, manufacture, transportation and commercial services occupation, low education level and smoking onset age less than 18 years old had a high risk of high tobacco dependence. Conclusions: The proportion of high tobacco dependence among current smokers aged 40 or older is high in China, so there is a huge demand for smoking cessation interventions. Effective measures should be taken to promote smoking cessation intervention in China.
