Abstract
Background Exosomes derived from bone marrow mesenchymal stem cells (MSC-exo) have been considered as a promising cell-free therapeutic strategy for ischemic heart disease. Cardioprotective drug pretreatment could be an effective approach to improve the efficacy of MSC-exo. Nicorandil has long been used in clinical practice for cardioprotection. This study aimed to investigate whether the effects of exosomes derived from nicorandil pretreated MSC (MSCNIC-exo) could be enhanced in facilitating cardiac repair after acute myocardial infarction (AMI). Methods MSCNIC-exo and MSC-exo were collected and injected into the border zone of infarcted hearts 30 minutes after coronary ligation in rats. Macrophage polarization was detected 3 days post-infarction, cardiac function as well as histological pathology were measured on the 28th day after AMI. Macrophages were separated from the bone marrow of rats for in vitro model. Exosomal miRNA sequencing was conducted to identify differentially expressed miRNAs between MSCNIC-exo and MSC-exo. MiRNA mimics and inhibitors were transfected to MSCs or macrophages to explore the specific mechanism. Results Compared to MSC-exo, MSCNIC-exo showed superior therapeutic effects on cardiac functional and structural recovery after AMI and markedly elevated the ratio of CD68+ CD206+/ CD68+cells in infarcted hearts 3 days post-infarction. The notable ability of MSCNIC-exo to promote macrophage M2 polarization was also confirmed in vitro. Exosomal miRNA sequencing and both in vivo and in vitro experiments identified and verified that miR-125a-5p was an effector of the roles of MSCNIC-exo in vivo and in vitro. Furthermore, we found miR-125a-5p promoted macrophage M2 polarization by inhibiting TRAF6/IRF5 signaling pathway. Conclusion This study suggested that MSCNIC-exo could markedly facilitate cardiac repair post-infarction by promoting macrophage M2 polarization by upregulating miR-125a-5p targeting TRAF6/IRF5 signaling pathway, which has great potential for clinical translation.

Abstract
PURPOSE In recent decades, the occurrence of heart failure with preserved ejection fraction (HFpEF) has outweighed that of heart failure with reduced ejection fraction by degrees, but few drugs have been demonstrated to improve long-term clinical outcomes in patients with HFpEF. Levosimendan, a calcium-sensitizing cardiotonic agent, improves decompensated heart failure clinically. However, the anti-HFpEF activities of levosimendan and underlying molecular mechanisms are unclear. METHODS In this study, a double-hit HFpEF C57BL/6N mouse model was established, and levosimendan (3 mg/kg/week) was administered to HFpEF mice aged 13 to 17 weeks. Different biological experimental techniques were used to verify the protective effects of levosimendan against HFpEF. RESULTS After four weeks of drug treatment, left ventricular diastolic dysfunction, cardiac hypertrophy, pulmonary congestion, and exercise exhaustion were significantly alleviated. Junction proteins in the endothelial barrier and between cardiomyocytes were also improved by levosimendan. Among the gap junction channel proteins, connexin 43, which was especially highly expressed in cardiomyocytes, mediated mitochondrial protection. Furthermore, levosimendan reversed mitochondrial malfunction in HFpEF mice, as evidenced by increased mitofilin and decreased ROS, superoxide anion, NOX4, and cytochrome C levels. Interestingly, after levosimendan administration, myocardial tissue from HFpEF mice showed restricted ferroptosis, indicated by an increased GSH/GSSG ratio; upregulated GPX4, xCT, and FSP-1 expression; and reduced intracellular ferrous ion, MDA, and 4-HNE levels. CONCLUSION Regular long-term levosimendan administration can benefit cardiac function in a mouse model of HFpEF with metabolic syndromes (namely, obesity and hypertension) by activating connexin 43-mediated mitochondrial protection and sequential ferroptosis inhibition in cardiomyocytes.

Abstract
Despite several recent advances, current therapy and prevention strategies for myocardial infarction are far from satisfactory, owing to limitations in their applicability and treatment effects. Nanoparticles (NPs) enable the targeted and stable delivery of therapeutic compounds, enhance tissue engineering processes, and regulate the behaviour of transplants such as stem cells. Thus, NPs may be more effective than other mechanisms, and may minimize potential adverse effects. This review provides evidence for the view that function-oriented systems are more practical than traditional material-based systems; it also summarizes the latest advances in NP-based strategies for the treatment and prevention of myocardial infarction.

Abstract
AIMS Interleukin (IL)-5 mediates the development of eosinophils (EOS) that are essential for tissue post-injury repair. It remains unknown whether IL-5 plays a role in heart repair after myocardial infarction (MI). This study aims to test whether IL-5-induced EOS population promotes the healing and repair process post-MI and to reveal the underlying mechanisms. METHOD AND RESULTS MI was induced by permanent ligation of the left anterior descending coronary artery in wild-type C57BL/6 mice. Western blot and real-time polymerase chain reaction revealed elevated expression of IL-5 in the heart at 5 days post-MI. Immunohistostaining indicated that IL-5 was secreted mainly from macrophages and type 2 innate lymphoid cells in the setting of experimental MI. External supply of recombinant mouse IL-5 (20 min, 1 day, and 2 days after MI surgery) reduced the infarct size and increased ejection fraction and angiogenesis in the border zone. A significant expansion of EOS was detected in both the peripheral blood and infarcted myocardium after IL-5 administration. Pharmacological depletion of EOS by TRFK5 pretreatment muted the beneficial effects of IL-5 in MI mice. Mechanistic studies demonstrated that IL-5 increased the accumulation of CD206+ macrophages in infarcted myocardium at 7 days post-MI. In vitro co-culture experiments showed that EOS shifted bone marrow-derived macrophage polarization towards the CD206+ phenotypes. This activity of EOS was abolished by IL-4 neutralizing antibody, but not IL-10 or IL-13 neutralization. Western blot analyses demonstrated that EOS promoted the macrophage downstream signal transducer and activator of transcription 6 (STAT6) phosphorylation. CONCLUSION IL-5 facilitates the recovery of cardiac dysfunction post-MI by promoting EOS accumulation and subsequent CD206+ macrophage polarization via the IL-4/STAT6 axis. TRANSLATIONAL PERSPECTIVE Accumulating evidence suggests that modulation of innate and adaptive immune responses is a promising therapeutic strategy for myocardial infarction. In this study, we demonstrate that IL-5 exerts cardioprotective effects on infarcted myocardium by promoting eosinophil accumulation and subsequent CD206+ macrophage polarization via the IL-4/STAT6 axis. Hence, regulation of cardiac IL-5 level or eosinophil count may become a therapeutic approach for post-myocardial infarction cardiac repair in humans.

Abstract
Acute myocardial infarction (AMI) is an event of ischemic myocardial necrosis caused by acute coronary artery occlusion, which ultimately leads to a large loss of cardiomyocytes. The prerequisite of salvaging ischemic myocardium and improving cardiac function of patients is to provide adequate blood perfusion in the infarcted area. Apart from reperfusion therapy, it is also urgent and imperative to promote angiogenesis. Recently, growing evidence based on promising preclinical data indicates that mesenchymal stem cells (MSCs) can provide therapeutic effects on AMI by promoting angiogenesis. Extracellular vesicles (EVs), membrane-encapsulated vesicles with complex cargoes, including proteins, nucleic acids, and lipids, can be derived from MSCs and represent part of their functions, so EVs also possess the ability to promote angiogenesis. However, poor control of the survival and localization of MSCs hindered clinical transformation and made scientists start looking for new approaches based on MSCs. Identifying the role of MSCs and their derived EVs in promoting angiogenesis can provide a theoretical basis for improved MSC-based methods, and ultimately promote the clinical treatment of AMI. This review highlights potential proangiogenic mechanisms of transplanted MSCs and the derived EVs after AMI and summarizes the latest literature concerning the novel methods based on MSCs to maximize the angiogenesis capability.

Abstract
Acute myocardial infarction (AMI) is one of the leading causes of mortality around the world, and the inflammatory response plays a pivotal role in the progress of myocardial necrosis and ventricular remodeling, dysfunction and heart failure after AMI. Therapies aimed at modulating immune response after AMI on a molecular and cellular basis are urgently needed. Exosomes are a type of extracellular vesicles which contain a large amount of biologically active substances, like lipids, nucleic acids, proteins and so on. Emerging evidence suggests key roles of exosomes in immune regulation post AMI. A variety of immune cells participate in the immunomodulation after AMI, working together to clean up necrotic tissue and repair damaged myocardium. Stem cell therapy for myocardial infarction has long been a research hotspot during the last two decades and exosomes secreted by stem cells are important active substances and have similar therapeutic effects of immunomodulation, anti-apoptosis, anti-fibrotic and angiogenesis to those of stem cells themselves. Therefore, in this review, we focus on the characteristics and roles of exosomes produced by both of endogenous immune cells and exogenous stem cells in myocardial repair through immunomodulation after AMI.

Abstract
OBJECTIVE To test whether intensive atorvastatin (ATV) increases the efficacy of transplantation with autologous bone marrow mononuclear cells (MNCs) in patients suffering from anterior ST-elevated myocardial infarction (STEMI). METHODS This clinical trial was under a 2×2 factorial design, enrolling 100 STEMI patients, randomly into four groups of regular (RA) or intensive ATV (IA) with MNCs or placebo. The primary endpoint was the change of left ventricular ejection fraction (LVEF) at 1-year follow-up from baseline, primarily assessed by MRI. The secondary endpoints included other parameters of cardiac function, remodelling and regeneration determined by MRI, echocardiography, positron emission tomography (PET) and biomarkers. RESULTS All the STEMI patients with transplantation of MNCs showed significantly increased LVEF change values than those with placebo (p=0.01) with only in the IA+MNCs patients group demonstrating significantly elevation of LVEF than in the IA+placebo group (+12.6% (95%CI 10.4 to 19.3) vs +5.0% (95%CI 4.0 to 10.0), p=0.001), pointing to a better synergy between ATV and MNCs (p=0.019). PET analysis revealed significantly increased viable areas of myocardium (p=0.015), while the scar sizes (p=0.026) and blood aminoterminal pro-B-type natriuretic peptide (p<0.034) reduced. All these above benefits of MNCs were also attributed to IA+MNCs instead of RA+MNCs group of patients with STEMI. CONCLUSIONS Intensive ATV treatment augments the therapeutic efficacy of MNCs in patients with anterior STEMI at the convalescent stage. The treatment with the protocol of intensive ATV and MNC combination offers a clinically essential approach for myocardial infarction. TRIAL REGISTRATION NUMBER NCT00979758.

Abstract
Objective: To analyze the clinical features and prognosis of lung cancer patients with metastasis-induced acute pancreatitis (MIAP), and to provide clues for early diagnosis. Methods: The characteristics and prognosis of 8 patients with MIAP in lung cancer admitted to Peking Union Medical College Hospital from January 2002 to September 2019 were retrospectively analyzed and were compared with non-tumor-induced AP. Results: Sevencases(7/8) were Mild AP, one (1/8) was Severe AP. Four patients (4/8) presented with AP as the reporting sign and lung cancer was not diagnosed until (112±36) days after the onset of AP. Clinical manifestations included abdominal pain (8/8), weight loss (4/8), nausea and vomiting (2/8), and jaundice (1/8). Stages of lung cancer were all Ⅳ.Histopathology proved that seven cases (7/8) were small cell lung cancer, and one case (1/8) was poorly differentiated adenocarcinoma. The median survival time was 11 months. Compared with non-tumor-induced AP, lung cancer patients with MIAP were older[(62±9) vs (48±15), P=0.018], the incidence of primary pancreatic duct dilatation (37.5% vs 3.1%, P=0.004) and abdominal lymphadenopathy (37.5% vs 6.3%, P=0.017) were higher; the level of hemoglobin [105.3±15.6) g/L vs (147.9±24.8) g/L, P<0.001] and hematocrit [(31.4±5.3) vs (42.5±6.1), P<0.001] were lower. Conclusions: Patientswith MIAP in lung cancer had poor outcome and unspecific symptoms. Old age, anemia, main pancreatic duct dilatation and abdominal lymphadenopathy are diagnostic clues that merit clinical attention.

Abstract
The SDF-1/CXCR4 signaling plays a critical role in the trafficking of mesenchymal stem cells (MSCs) to the sites of tissue damage. Our recent study demonstrated that atorvastatin (ATV) treatment improved the survival of MSCs, and ATV pretreated MSCs (ATV-MSCs) exhibited enhanced engraftment to injured myocardium. In this study, we investigated whether combined treatment with ATV and ATV-MSCs enhances cardiac repair and regeneration by activating SDF-1/CXCR4 signaling in a rat model of acute myocardial infarction. Rats were randomized into eight groups: the Sham, AMI control and 6 other groups that were subjected to AMI followed by treatment with MSCs, ATV, ATV+MSCs, ATV-MSCs, ATV+ATV-MSCs, ATV+ATV-MSCs+AMD3100 (SDF-1/CXCR4 antagonist), respectively. ATV+ATV-MSCs significantly potentiated targeted recruitment of MSCs to peri-infarct myocardium and resulted in further improvements in cardiac function and reduction in scar size compared with MSCs treatment alone at 4-week after AMI. More importantly, the cardioprotective effects conferred by ATV+ATV-MSCs were almost completely abolished by AMD3100 treatment. Together, our study demonstrated that ATV+ATV-MSCs significantly enhanced the targeted recruitment and survival of transplanted MSCs, and resulted in subsequent cardiac function improvement by augmenting SDF-1/CXCR4 signaling.

Abstract
Objective: To provide helpful continued medical education (CME) for physicians and improve gout treatment, we conducted a questionnaire survey to investigate physicians' knowledge in nine districts of Beijing. Methods: A questionnaire survey including ten gout-related questions was conducted among 298 physicians in Beijing. Demographic data and previous gout CME experience were collected. Chi-square test or Student's t test, univariate analysis and logistic regression analysis were used to evaluate the relevant factors of physicians' knowledge level. Results: A total of 250 valid copies were collected including 127 from community service centers (CSC), 123 from tertiary hospitals. The correct answer rate of gout etiology, pathogenesis and attack symptoms were over 70% in both groups. 45.5% (56/123) CSC doctors and 57.4% (66/115) tertiary doctors answered right drugs to control acute gout attack (P=0.067). Only 42.3% (52/123) in CSC and 53.4% (63/118) in hospitals chose allopurinol as a urate-lowering drug (ULT), while 46.3% (57/123) and 32.2% (38/118) doctors considered colchicine as a ULT drug (P=0.084) respectively. Near half doctors considered that gout patients should take long-term ULT [40.5% (51/126) vs. 57.6%(68/118)respectively, P=0.007]. Univariate analysis showed that CME training could improve gout-related knowledge in CRC doctors. Conclusion: Most CSC doctors generally understand basic knowledge of gout, while confusion of treatment is still significant. CME especially including standard gout treatment should be performed by doctors in tertiary hospitals.

Abstract
Objective: To summarize the experience of renal autotransplantation for severe iatrogenic proximal ureteral damage and renal artery aneurysms in eight patients and to explore the clinical application value of renal autotransplantation. Methods: Two patients of renal artery aneurysms and six patients of severe iatrogenic proximal ureteral damage between January 2010 and March 2018 in our center were retrospectively reviewed. Results: The procedures of eight cases were successful, with immediate return of renal function in the patients. The warm ischemia time was (3±1) minutes, the total operation time was (340±164) min, and the estimated blood loss was (180±60) ml, respectively. For renal artery anastomosis, six patients of severe iatrogenic proximal ureteral damage received end-to-end anastomosis between the internal iliac artery and renal artery, and two patients of renal artery aneurysms were treated with renal artery and internal iliac artery for reconstruction, then end-to-side anastomosis to recipien external iliac artery. A direct ureterovesical anastomosis was performed in seven patients, one patient was received pyeloureteroplasty. No serious complications of blood vessel and ureter were found during perioperative and long-term follow-up. All cases follow-up hitherto have normal renal function and blood pressure. Conclusions: Renal autotransplantation can be appropriate for patients with proximal ureteral loss and complex hilar renal artery aneurysms. In addition, it is able to protect renal functions to the most extent and provides a surgical alterative for complex renal diseases.

Abstract
Type 2 immunity participates in the pathogeneses of helminth infection and allergic diseases. Emerging evidence indicates that the components of type 2 immunity are also involved in maintaining metabolic hemostasis and facilitating the healing process after tissue injury. Numerous preclinical studies have suggested regulation of type 2 immunity-related cytokines, such as interleukin-4, -13, and -33, and cell types, such as M2 macrophages, mast cells, and eosinophils, affects cardiac functions after myocardial infarction (MI), providing new insights into the importance of immune modulation in the infarcted heart. This review provides an overview of the functions of these cytokines and cells in the setting of MI as well as their potential to predict the severity and prognosis of MI.

Abstract
Objective: To fabricate Ti alloy frameworks for a maxillary complete denture with three-dimensional printing (3DP) technique, such as selective laser melting (SLM) and electron beam melting (EBM), and to evaluate the microstructure of these frameworks and their adaptation to the die stone models. Methods: Thirty pairs of edentulous casts were divided into 3 groups randomly and equally. In each group, one of the three techniques (SLM, EBM, conventional technique) was used to fabricate Ti alloy frameworks. The base-cast sets were transversally sectioned into 3 sections at the distal of canines, mesial of first molars, and the posterior palatal zone. The gap between the metal base and cast was measured in the 3 sections. Stereoscopic microscope was used to measure the gap. Three pieces of specimens of 5 mm diameter were fabricated with Ti alloy by SLM, EBM and the traditional casting technology (as mentioned above). Scanning electron microscope (SEM) was used to evaluate the differences of microstructure among these specimens. Results: The gaps between the metal base and cast were (99.4±17.0), (98.2±26.1), and (99.6± 16.1) μm in conventional method; (99.4 ± 22.8), (83.1 ± 19.3), and (103.3 ± 13.8) μm in SLM technique; (248.3±70.3), (279.1±71.9), and (189.1±31.6) μm in EBM technique. There was no statistical difference in the value of gaps between SLM Ti alloy and conventional method Ti alloy group (P>0.05). There was statistical difference among EBM Ti alloy, conventional method Ti alloy and SLM Ti alloy group (P<0.05). The SLM Ti alloy showed more uniform and compact microstructure than the cast Ti alloy and EBM Ti alloy did. Conclusions: SLM technique showed initial feasibility to manufacture the dental base of complete denture. The mechanical properties and microstructure of the denture frameworks prepared by SLM indicate that these dentures are appropriate for clinical use. EBM technique is inadequate to make a complete denture now.

Abstract
OBJECTIVE The aim of this study was to explore a panel of useful markers in differential diagnosis of primary endocervical adenocarcinoma (ECA) and endometrial adenocarcinoma (EMA). Materials anid Methods: Thirty-three ECAs and 31 EMAs were collected and examined for high-risk human papillomavirus (hr-HPV) (16/18) DNA using in situ hybridization, and for p16, vimentin, ER, PR expression using immunohistochemistry (IHC). RESULTS Detection rate of hr-HPV (16/18) DNA in ECA (72.7%, 24/33) was significantly higher than that in EMA (12.9%, 4/31) (p < 0.01). Twenty-four of 33 (72.7%) cases of ECA, but only five of 31 (16.1%) cases of EMA showed high expression of pl6. Twenty-three of 24 (95.8%) hr-HPV DNA-positive ECA and all four (100.0%) hr-HPV DNA-positive EMA showed high levels of pl6 expression. High expression rates of vimentin (90.3%, 28/31), ER (58.1%, 18/31), and PR (71.0%, 22/31) in EMA were significantly higher than those in ECA, respectively (p < 0.01). CONCLUSION Detection of hr-HPV DNA combined with immunohistochemical expressions of pl6, vimentin, ER, and PR have important value in differential diagnosis between ECA and EMA.

Abstract
The levels and health risks of arsenic and heavy metals (As, Ba, Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn) in the suspended particulate matter (SPM) collected from an urban household environment in Beijing of China for 12 months were investigated. The mean concentrations of the studied toxic elements were higher and lower than crustal abundance and PM2.5 in the urban outdoors of Beijing. The concentrations of the studied elements displayed significant seasonality. The highest concentrations of the total elements occurred in winter, followed by autumn, while the lowest concentrations were recorded in summer. Based on the calculated values of enrichment factor (EF) and geoaccumulation index (Igeo), the levels for As and Cu were heavily contaminated, while those for Cd, Pb, and Zn were extremely contaminated. As and Pb might pose risks to children and adults via ingestion exposure. The accumulative risks of multi-elements resulted from dermal contact and inhalation exposures were not negligible. More attention should be paid to reducing the non-carcinogenic and carcinogenic health risks posed by the toxic elements bound to urban household SPM particles via ingestion, inhalation, and dermal contact exposure.

Abstract
Different pig breeds have shown differential susceptibility to the pathogen infection; however, molecular mechanisms of the infection susceptibility are not fully understood. Streptococcus suis type 2 (SS2) is an important zoonotic pathogen. To identify the genes responsible for infection susceptibility, pigs from two different breeds (Enshi black and Landrace) were inoculated with SS2 and their spleen transcriptome profiles were investigated in the present study. The differentially expressed genes (DEGs) were analyzed from infected versus control pigs in each breed, and then compared between both pig breeds. Enshi black pig showed more DEGs than Landrace (830 vs. 611) and most of these were due to down-regulated genes (543 vs. 387). However some DEGs were uniquely expressed in one breed, some were expressed in opposite direction in both breeds. A number of candidate genes and pathways are identified which might be involved in susceptibility to SS2, for example, MMP9 and Resistin were only significantly expressed in Landrace. NPG3 and PMAP23 were up-regulated in Landrace whereas down-regulated in Enshi black. LENG8 in control Landrace have inherently higher expression than control Enshi black. IGKV6 is down-regulated in Landrace but up-regulated in Enshi black. Overall, the transcriptome profiles are consistent with the clinical signs, i.e. the Enshi black is more susceptible to SS2 infection than Landrace. This is the first study to identify differential gene expression between indigenous and modern commercial pigs after in vivo SS2 infection using RNA-seq. The significant DEGs in splenic profiles between two pig breeds suggested considerable involvement of genetic background in susceptibility to the SS2 infection in pigs.

Abstract
OBJECTIVE The aim of this study was to explore the potentiality of beta-catenin, Glut-1 and PTEN proteins as markers for a diagnosis of endometrial intraepithelial neoplasia (EIN). DESIGN Ten proliferative endometrium, 83 endometrial hyperplasia (59 benign hyperplasia, 24 EIN) and 24 endometrioid adenocarcinoma sections were immunostained for beta-catenin, Glut-1 and PTEN protein expression. RESULTS (1) Abnormal expression of beta-catenin was detected in 10% of benign hyperplasia, 50% of EIN and 67% of endometriold adenocarcinoma. (2) Overexpression of Glut-1 was present in 58% of EIN and 71% of endometrioid adenocarcinoma. (3) Complete loss of PTEN immunoreactivity was found in 20% of proliferative endometrium, 29% of benign hyperplasia, 38% of EIN and 63% of endometrioid adenocarcinoma. CONCLUSIONS The abnormal expression of beta-catenin and overexpression of Glut-1 may be useful markers in distinguishing benign hyperplasia from EIN, whereas lack of PTEN expression is not an appropriate marker for a diagnosis of EIN.

Abstract
The expression of placental hormones in 91 malignant trophoblastic neoplasms was studied immunohistochemically using a panel of antibodies against hCG, human placental lactogen (hPL) and pregnancy-specific 1-glycoprotein (SP). The results indicated that the expression of hCG in invasive moles was weaker than that in choriocarcinoma, but the expression of hPL and SP1 was stronger than those in choriocarcinoma. The expression of hPL and SP1 in the metastatic tumors of invasive moles was weaker than the expression at in the primary tumors, but the secretory capacity of hCG in metastatic choriocarcinomas was stronger than that in the primary neoplasms. In this study, the qualities of expression of the placental hormones in invasive moles and choriocarcinomas corresponded to the degree of tumor malignancy, the biological behaviour and the grading of trophoblastic cell differentiation. We believe that the detection of hCG, hPL and SP1, in malignant trophoblastic neoplasms was of value for establishing tumor diagnosis and typing and for judgement on prognosis.
