Abstract
Previous studies have demonstrated that the underlying mechanisms of myocardial ischemia/reperfusion injury (MIRI) are complex and involve multiple types of regulatory cell death, including ferroptosis, apoptosis, and autophagy. Thus, we aimed to identify the mechanisms underlying MIRI and validate the protective role of epigallocatechin-3-gallate (EGCG) and its related mechanisms in MIRI. An in vivo and in vitro models of MIRI were constructed. The results showed that pretreatment with EGCG could attenuate MIRI, as indicated by increased cell viability, reduced lactate dehydrogenase (LDH) activity and apoptosis, inhibited iron overload, abnormal lipid metabolism, preserved mitochondrial function, decreased infarct size, maintained cardiac function, decreased reactive oxygen species (ROS) level, and reduced TUNEL-positive cells. Additionally, EGCG pretreatment could attenuate ferroptosis, apoptosis, and autophagy induced by MIRI via upregulating 14-3-3η protein levels. Furthermore, the protective effects of EGCG could be abolished with pAd/14-3-3η-shRNA or Compound C11 (a 14-3-3η inhibitor) but not pAd/NC-shRNA. In conclusion, EGCG pretreatment attenuated ferroptosis, apoptosis, and autophagy by mediating 14-3-3η and protected cardiomyocytes against MIRI.

Abstract
Purpose Sinomenine hydrochloride (SH) is used to treat chronic inflammatory diseases such as rheumatoid arthritis and may also be efficacious against Immunoglobulin A nephropathy (IgAN). However, no trial has investigated the molecular mechanism of SH on IgAN. Therefore, this study aims to investigate the effect and mechanism of SH on IgAN. Methods The pathological changes and IgA and C3 depositions in the kidney of an IgAN rat model were detected by periodic acid-Schiff (PAS) and direct immunofluorescence staining. After extracting T and B cells using immunomagnetic beads, we assessed their purity, cell cycle phase, and apoptosis stage through flow cytometry. Furthermore, we quantified cell cycle-related and apoptosis-associated proteins by Western blotting. Results SH reduced IgA and C3 depositions in stage 4 IgAN, thereby decreasing inflammatory cellular infiltration and mesangial injury in an IgAN model induced using heteroproteins. Furthermore, SH arrested the cell cycle of lymphocytes T and B from the spleen of IgAN rats. Regarding the mechanism, our results demonstrated that SH regulated the Cyclin D1 and Cyclin E1 protein levels for arresting the cell cycle and it also regulated Bax and Bcl-2 protein levels, thus increasing Cleaved caspase-3 protein levels in Jurkat T and Ramos B cells. Conclusion SH exerts a dual regulation on the cell cycle and apoptosis of T and B cells by controlling cell cycle-related and apoptosis-associated proteins; it also reduces inflammatory cellular infiltration and mesangial proliferation. These are the major mechanisms of SH in IgAN.

Abstract
Embryo implantation requires temporospatial maternal-embryonic dialog. Using single-cell RNA sequencing for the uterus from 2.5 to 4.5 days post-coitum (DPC) and bulk sequencing for the corresponding embryos of 3.5 and 4.0 DPC pregnant mice, we found that estrogen-responsive luminal epithelial cells (EECs) functionally differentiated into adhesive epithelial cells (AECs) and supporting epithelial cells (SECs), promoted by progesterone. Along with maternal signals, embryonic Pdgfa and Efna3/4 signaling activated AECs and SECs, respectively, enhancing the attachment of embryos to the endometrium and furthering embryo development. This differentiation process was largely conserved between humans and mice. Notably, the developmental defects of SOX9-positive human endometrial epithelial cells (similar to mouse EEC) were related to thin endometrium, whereas functional defects of SEC-similar unciliated epithelial cells were related to recurrent implantation failure (RIF). Our findings provide insights into endometrial luminal epithelial cell development directed by maternal and embryonic signaling, which is crucial for endometrial receptivity.

Abstract
BACKGROUND The early life stage is critical for the gut microbiota establishment and development. We aimed to investigate the lifelong impact of famine exposure during early life on the adult gut microbial ecosystem and examine the association of famine-induced disturbance in gut microbiota with type 2 diabetes. METHODS We profiled the gut microbial composition among 11,513 adults (18-97 years) from three independent cohorts and examined the association of famine exposure during early life with alterations of adult gut microbial diversity and composition. We performed co-abundance network analyses to identify keystone taxa in the three cohorts and constructed an index with the shared keystone taxa across the three cohorts. Among each cohort, we used linear regression to examine the association of famine exposure during early life with the keystone taxa index and assessed the correlation between the keystone taxa index and type 2 diabetes using logistic regression adjusted for potential confounders. We combined the effect estimates from the three cohorts using random-effects meta-analysis. RESULTS Compared with the no-exposed control group (born during 1962-1964), participants who were exposed to the famine during the first 1000 days of life (born in 1959) had consistently lower gut microbial alpha diversity and alterations in the gut microbial community during adulthood across the three cohorts. Compared with the no-exposed control group, participants who were exposed to famine during the first 1000 days of life were associated with consistently lower levels of keystone taxa index in the three cohorts (pooled beta - 0.29, 95% CI - 0.43, - 0.15). Per 1-standard deviation increment in the keystone taxa index was associated with a 13% lower risk of type 2 diabetes (pooled odds ratio 0.87, 95% CI 0.80, 0.93), with consistent results across three individual cohorts. CONCLUSIONS These findings reveal a potential role of the gut microbiota in the developmental origins of health and disease (DOHaD) hypothesis, deepening our understanding about the etiology of type 2 diabetes.

Abstract
Alpiniamides E-G, three previously unreported linear polyketide derivatives, along with two known compounds, were isolated from Streptomyces sp. QHA48, which was isolated from the saline lakes of Qinghai-Tibet Plateau. The structures of these compounds were determined through analysis of their spectroscopic data, as well as density functional theory prediction of NMR chemical shifts, application of the DP4+ algorithm and electronic circular dichroism (ECD) calculations. In a cell-based lipid-lowering assay, all five alpiniamides exhibited significant inhibition of lipid accumulation in HepG2 cells without inducing cytotoxic effects at a concentration of 27 μM.

Abstract
Objective: To investigate the effects of two-step retraction and en-masse retraction on tooth movement pattern of anterior teeth and posterior anchorage with clear aligners using three-dimensional finite element analysis. Methods: A finite element model of maxillary first premolar extraction case undergoing clear aligner treatment was established based on maxillofacial cone-beam CT data of a 24-year-old adult male with individual normal occlusion, who visited Department of Oral Surgery, Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine for impacted mandibular third molar in June, 2022. The initial tooth displacement of five anterior retraction protocols (two-step with canine retraction, two-step with incisor bodily retraction, two-step with incisor retraction-overtreatment, en-masse bodily retraction, and en-masse retraction-overtreatment) were evaluated. Results: Two step with canine retraction caused distal tipping of the canine and labial tipping of the incisors (0.18° for central incisor and 0.13° for lateral incisor). Two step with incisor retraction caused mesial tipping of the canine. In two step with bodily retraction protocol, uncontrolled lingual tipping was found in central incisor (0.29°) and lateral incisor (0.32°). In two-step with incisor retraction-overtreatment protocol, the movement pattern of the incisors didn't change, but the inclinations reduced to 0.21° and 0.18°. En-masse retraction caused distal tipping of the canine. In en-masse bodily retraction protocol, uncontrolled lingual tipping was also found in central incisor (0.19°) and lateral incisor (0.27°). In en-masse retraction-overtreatment protocol, the central incisor showed controlled lingual tipping (0.02°) and the lateral incisor showed palatal root movement (0.03° labial inclination). Posterior teeth exhibited mesial tipping in all five protocols. Conclusion: En-masse retraction with incisor overtreatment was beneficial to incisor torque control in clear aligner treatment.

Methods: In this prospective open-label single-arm study, the data of 4 patients were collected from the pediatric department in Peking Union Medical College Hospital from December 2020 to December 2022. All of them were diagnosed by gene sequencing and had neutropenia. These patients received empagliflozin treatment. Their clinical symptoms such as height and weight increase, abdominal pain, diarrhea, oral ulcer, infection times, and drug applications were recorded at 2 weeks, 1 month, 2 months, 3 months, 6 months, 9 months, 12 months, and 15 months after treatment to assess the therapeutic effect. The liquid chromatography-tandem mass spectrometry method was used to monitor the changes in 1, 5-anhydroglucitol (1, 5AG) concentration in plasma. At the same time, adverse reactions such as hypoglycemia and urinary tract infection were closely followed up and monitored. Results: The 4 patients with GSD Ⅰb were 15, 14, 4 and 14 years old, respectively at the beginning of empagliflozin treatment, and were followed up for 15, 15, 12 and 6 months, respectively. Maintenance dose range of empagliflozin was 0.24-0.39 mg/(kg·d). The frequency of diarrhea and abdominal pain decreased in cases 2, 3, and 4 at 1, 2 and 3 months of treatment, respectively. Their height and weight increased at different degrees.The absolute count of neutrophils increased from 0.84×109, 0.50×109, 0.48×109, 0.48×109/L to 1.48×109, 3.04×109, 1.10×109, 0.73×109/L, respectively. Granulocyte colony-stimulating factor was gradually reduced in 1 patients and stopped in 3 patient. Plasma 1, 5 AG levels in 2 children were significantly decreased after administration of empagliflozin (from 46.3 mg/L to 9.6 mg/L in case 2, and from 56.1 mg/L to 15.0 mg/L in case 3). All 4 patients had no adverse reactions such as hypoglycemia, abnormal liver or kidney function, or urinary system infection. Conclusion: In short-term observation, empagliflozin can improve the symptoms of GSD Ⅰb oral ulcers, abdominal pain, diarrhea, and recurrent infection, also can alleviate neutropenia and decrease 1, 5AG concentration in plasma, with favorable safety.

Abstract
BACKGROUND & AIMS Previous studies have suggested that circulating 25-hydroxyvitamin D (25 [OH]D, VD) and the gut microbiota-bile acid axis play crucial roles in metabolic health. Exploring the mediating role of the gut microbiota-bile acid axis would improve our understanding of the mechanisms underlying the effects of VD on human metabolic health. This study examined the association between plasma 25(OH)D and the prevalence/incidence of metabolic syndrome (MetS) and the mediating role of the gut microbiota-bile acid axis. METHODS This prospective study included 3180 participants with plasma 25(OH)D data at baseline and 2966 participants with a 9-year follow-up. MetS was determined every three years. The gut microbiota was analyzed by 16S rRNA sequencing in 1752 participants, and targeted bile acid metabolites in feces were further determined in 974 participants using UPLC‒MS/MS at the middle of the study. Mediating roles of microbiota and bile acids in the VD-MetS associations were analyzed using mediation/path analyses adjusted for potential confounders. RESULTS Among the 2966 participants who were followed-up, 1520, 193, 647, and 606 were MetS-free (normal), recovered, had incident MetS, and had persistent MetS, respectively. The multivariable-adjusted ORs (95% CIs) of MetS prevalence were 0.65 (0.50, 0.84) for baseline MetS and 0.46 (0.33, 0.65) for 9-year persistent MetS in quartile 4 (compared to quartile 1) of plasma 25(OH)D (median: 37.7 vs. 19.6, ng/ml). The corresponding HR (95% CI) of 9-year MetS incidence was 0.71 (0.56, 0.90) (all P-trend < 0.05). Higher VD concentrations were associated with greater α-diversity of the gut microbiota, which was inversely correlated with MetS risk. The groups classified by VD and MetS status had significantly different β-diversity. Ruminiclostridium-6 and Christensenellaceae R-7 group were enriched in the high-VD group and were inversely associated with MetS. However, opposite associations were observed for Lachnoclostridium and Acidaminococcus. The overlapping differential microbial score (ODMS) developed from the four differential genera explained 12.2% of the VD-MetS associations (Pmediation = 0.015). Furthermore, the fecal bile acid score created from 11 differential bile acids related to ODMS and MetS mediated 34.2% of the association between ODMS and MetS (Pmediation = 0.029). Path analyses showed that the inverse association between plasma 25(OH)D and MetS could be mediated by the gut microbiota-bile acid axis. CONCLUSIONS The findings suggest that the gut microbiota-bile acid axis partially mediates the beneficial association between plasma 25(OH)D and the risk of persistent MetS and incident MetS in the Chinese population.

Abstract
Objective: To explore the effects of porcine urinary bladder matrix (UBM) on the motility and polarization of bone marrow-derived macrophages in mice, so as to provide evidence for the rational selection of stent in clinical wound repair. Methods: The method of experimental research was used. The microstructure of porcine UBM and absorbable dressing was observed under scanning electron microscope. Polyacrylamide gel electrophoresis was used to observe the protein distribution of the two stent extracts. The primary macrophages were induced from bone marrow-derived cells isolated from six 6-8-week-old male C57BL/6J mice (mouse age, sex, and strain, the same below) and identified. Three batches of macrophages were divided into porcine UBM extract group and absorbable dressing extract group. The cells in each group were cultured with Dulbecco's modified Eagle medium/F12 medium containing the corresponding extracts. The cell migration rate was detected and calculated on 1, 3, and 7 d after scratching by scratch test. The number of migrated cells at 12 and 24 h of culture was detected by Transwell experiment. The percentages of CD206 and CD86 positive cells at 24 h of culture was detected by flow cytometer. The numbers of sample in the above cell experiments were all 3. An incision was prepared on the left and right back of twelve mice, respectively. The left incision of each mouse was included in porcine UBM group and the right incision was included in absorbable dressing group, and the corresponding stents were implanted into the incisions respectively. On post operation day (POD) 7 and 14, the number of inflammatory cells infiltrated in the stent was detected by hematoxylin-eosin staining; the number of F4/80, transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF), and matrix metalloprotein-9 (MMP-9) positive cells and type Ⅰ collagen deposition in stents were observed by immunohistochemistry; the percentages of F4/80, CD86, and CD206 positive cells were observed by immunofluorescence staining. The numbers of sample in the above animal experiments were all 6. Data were statistically analyzed with analysis of variance for factorial design, analysis of variance for repeated measurement, and independent sample t test. Results: Porcine UBM has a dense basement membrane structure on one side and porous propria containing a fibrous structures on the other. Both sides of the absorbable dressing had three-dimensional porous structure. In the molecular weight range of (50-70)×103, multiple non-type Ⅰ collagen bands appeared in the lanes of porcine UBM extract, while no obvious bands appeared in the lanes of absorbable dressing extract. It had been identified that mouse bone marrow-derived cells had been successfully induced into macrophages. The cell migration rates in porcine UBM extract group were significantly higher than those in absorbable dressing extract group on 1, 3, and 7 d after scratching (with t values of 15.31, 19.76, and 20.58, respectively, P<0.05). The numbers of migrated cells in porcine UBM extract group were significantly more than those in absorbable dressing extract group at 12 and 24 h of culture (with t values of 12.20 and 33.26, respectively, P<0.05). At 24 h of culture, the percentage of CD86 positive cells in porcine UBM extract group ((1.27±0.19)%) was significantly lower than (7.34±0.14)% in absorbable dressing extract group (t=17.03, P<0.05);the percentage of CD206 positive cells in porcine UBM extract group was (73.4±0.7)%, significantly higher than (32.2±0.5)% in absorbable dressing extract group (t=119.10, P<0.05). On POD 7 and 14, the numbers of inflammatory cells infiltrated in the stents in porcine UBM group was significantly more than those in absorbable dressing group (with t values of 6.58 and 10.70, respectively, P<0.05). On POD 7 and 14, the numbers of F4/80, TGF-β1, VEGF, and MMP-9 positive cells in the stents in porcine UBM group were significantly more than those in absorbable dressing group (with t values of 46.11, 40.69, 13.90, 14.15, 19.79, 32.93, 12.16, and 13.21, respectively, P<0.05); type Ⅰ collagen deposition in the stents in porcine UBM group was more pronounced than that in absorbable dressing group; the percentages of CD206 positive cells in the stents in porcine UBM group were significantly higher than those in absorbable dressing group (with t values of 5.05 and 4.13, respectively, P<0.05), while the percentages of CD86 positive cells were significantly lower than those in absorbable dressing group (with t values of 20.90 and 19.64, respectively, P<0.05), and more M2-type macrophages were seen in the stents in porcine UBM group and more M1-type macrophages were seen in the stents in absorbable dressing group. Conclusions: Porcine UBM can enhance macrophage motility, induce M2 polarization and paracrine function, create a microenvironment containing growth factors such as TGF-β1 and MMP-9 tissue remodeling molecules, and promote tissue regeneration and extracellular matrix remodeling in mice.

Abstract
CONTEXT Circulating proteomes may provide intervention targets for type 2 diabetes (T2D). OBJECTIVE We aimed to identify proteomic biomarkers associated with incident T2D and assess its joint effect with dietary or lifestyle factors on the T2D risk. METHODS We established 2 nested case-control studies for incident T2D: discovery cohort (median 6.5 years of follow-up, 285 case-control pairs) and validation cohort (median 2.8 years of follow-up, 38 case-control pairs). We integrated untargeted mass spectrometry-based proteomics and interpretable machine learning to identify T2D-related proteomic biomarkers. We constructed a protein risk score (PRS) with the identified proteomic biomarkers and used a generalized estimating equation to evaluate PRS-T2D relationship with repeated profiled proteome. We evaluated association of PRS with trajectory of glycemic traits in another non-T2D cohort (n = 376). Multiplicative interactions of dietary or lifestyle factors with PRS were evaluated using logistic regression. RESULTS Seven proteins (SHBG, CAND1, APOF, SELL, MIA3, CFH, IGHV1-2) were retained as the proteomic biomarkers for incident T2D. PRS (per SD change) was positively associated with incident T2D across 2 cohorts, with an odds ratio 1.29 (95% CI, 1.08-1.54) and 1.84 (1.19-2.84), respectively. Participants with a higher PRS had a higher probability showing unfavored glycemic trait trajectory in the non-T2D cohort. Red meat intake and PRS showed a multiplicative interaction on T2D risk in the discovery (P = 0.003) and validation cohort (P = 0.017). CONCLUSION This study identified proteomic biomarkers for incident T2D among the Chinese populations. The higher intake of red meat may synergistically interact with the proteomic biomarkers to exaggerate the T2D risk.

Abstract
Background To explore the feasibility of sentinel lymph node (SLN) tracing by percutaneous contrast-enhanced ultrasound (pCEUS) in patients with cutaneous malignant melanoma (CMM) and the ability to enhance patterns of SLNs in diagnosing lymph nodes (LNs) metastases. Methods Fifty-three patients with CMM of the lower extremities treated at our hospital were included in the study. All the participants received pCEUS preoperatively. The enhanced lymphatic channels (LCs) and associated SLNs were observed and tracked in real-time. The number of enhanced LCs and enhancing patterns of SLNs were recorded. Subsequently, SLNs localized by pCEUS were pathologically examined. Results Of the 53 cases, SLNs were successfully localized by pCEUS in 48 cases. In total, there were 59 detected SLNs averaging 1.23±0.42 SLNs per case. The main lymphatic drainage patterns (LDPs) were the following: one enhanced LC pointed to one or more than one SLN, and multiple enhanced LCs pointed to one or multiple SLNs. There were four enhancing patterns of SLNs (uniform, annular, uneven, and no enhancement), among which the first two were considered benign nodes, while the latter two were considered metastatic nodes. With pathological results as the gold standard, the diagnostic sensitivity and specificity by pCEUS were 90.9% and 75.0%, respectively. Conclusions Contrast-enhanced ultrasound (US) is a feasible approach for SLN identification in patients with CMM of the lower extremities. Enhancing patterns of SLNs may help predict metastasizing SLNs. This novel method may be a promising technique for clinical application.

Abstract
STUDY QUESTION How does ectopic endometrial stromal cell (Ecto-ESC)-derived extracellular vesicular Legumain pseudogene 1 (EV-LGMNP1), a newly identified pseudogene of Legumain (LGMN), contribute to M2-phenotype macrophage polarization, and does it predict recurrence in patients with ovarian endometriosis (EMs)? SUMMARY ANSWER EV-LGMNP1, which is abundant in Ecto-ESCs and serum from ovarian EMs, can direct macrophages towards an M2 phenotype by upregulating LGMN expression and is a promising biomarker for predicting ovarian EMs recurrence. WHAT IS KNOWN ALREADY Extracellular vesicles (EVs) can mediate cell-to-cell crosstalk to promote disease progression via cargo molecule transport. Recently, LGMNP1, a newly identified pseudogene of LGMN, has been reported to promote cancer progression by upregulating LGMN. LGMN is a well-studied protein that can induce M2-like polarization. STUDY DESIGN, SIZE, DURATION An in vitro study was conducted with Ecto-ESCs isolated from ectopic endometrial samples, collected from two patients with ovarian EMs (diagnosed by laparoscopy and histological analysis). A clinical retrospective cohort study of 52 ovarian EMs patients and 21 controls with available preoperative serum samples was carried out (2013-2017). The follow-up period ended either at the time of recurrence or on 31 December 2018. PARTICIPANTS/MATERIALS, SETTING, METHODS Ecto-ESC-derived EVs (EV/Ecto-ESCs) were characterized by nanoparticle tracking analysis, transmission electron microscopy and western blotting. EV internalization by THP-1 cells, which are the most widely used primary human macrophages model, was detected by fluorescence labelling. After EV treatment, THP-1 cell polarization was detected by quantitative real-time PCR (qRT-PCR) and western blot analyses of CD86 (M1-related marker) and CD206 (M2-related marker). LGMNP1 mRNA expression level in EVs from both primary ectopic endometrioc stromal cells and serum was examined using qRT-PCR. Additionally, the expression of LGMN, the downstream target gene of LGMNP1, in THP-1 cells was evaluated using qRT-PCR and western blotting. Kaplan-Meier and multivariate Cox regression analyses were applied to evaluate the independent predictive factors of EMs recurrence-free survival. A novel nomogram model based on serum EV-LGMNP1 was then formulated to predict EMs recurrence. MAIN RESULTS AND THE ROLE OF CHANCE In vitro assays demonstrated that EV/Ecto-ESCs drove macrophages towards an M2-like phenotype. Moreover, LGMNP1 contributed to EV/Ecto-ESC-induced M2 macrophage polarization by upregulating LGMN mRNA expression levels. Clinically, serum EV-LGMNP1 was more highly expressed in recurrent EMs patients than in controls and EMs patients without recurrence. Survival analysis and our novel nomogram reconfirmed that serum EV-LGMNP1 was a novel promising and meaningful non-invasive biomarker for predicting EMs recurrence. LARGE SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION In vitro experiments were only performed on samples from two patients with ovarian endometriosis, and a larger sample size is needed. ESCs isolated from the eutopic endometrium of EMs and non-EMs patients should be studied in the future. Additionally, in vitro experiments should be performed using endometrial epithelium cells and further in vivo experiments, such as using mice endometriotic models to investigate whether EV/Ecto could induce M2 macrophage polarization, should be conducted. Moreover, multicentre, large-sample data are needed to validate our predictive nomogram model. WIDER IMPLICATIONS OF THE FINDINGS Our study provides novel insights into the mechanism of M2 polarization involved in ovarian EMs progression mediated by an 'EV-shuttled pseudogene LGMNP1' mode. In addition, serum EV-LGMNP1 may serve as a novel non-invasive biomarker for predicting recurrence, providing a new therapeutic target for ovarian EMs. STUDY FUNDING/COMPETING INTEREST(S) This project was supported by funding from the National Natural Science Foundation of China (81971361), the Natural Science Foundation of Shanghai Science and Technology (19ZR1406900), the Shanghai 'Rising Stars of Medical Talent' Youth Development Program (AB83030002019004), the Clinical Research Plan of SHDC (SHDC2020CR4087), the Shanghai Municipal Health Commission (202040498), the Research and Innovation Project of the Shanghai Municipal Education Commission (2019-01-07-00-07-E00050) and the Clinical Research Plan of SHDC (SHDC2020CR1045B).

Abstract
BACKGROUND Many studies have examined associations between dietary isoflavones and atherosclerosis, but few used objective biomarkers. OBJECTIVES We examined the associations of isoflavone biomarkers (primary analyses) and equol production (secondary analyses) with the progression of carotid intima-media thickness (cIMT), and whether inflammation, systolic blood pressure (SBP), blood lipids, and sex hormone-binding globulin (SHBG) mediated these associations, in Chinese adults. METHODS This 8.8-y prospective study included 2572 subjects (40-75 y old) from the GNHS (Guangzhou Nutrition and Health Study; 2008-2019). The concentrations of daidzein, genistein, and equol were assayed by an HPLC-tandem MS in serum (n = 2572) at baseline and in urine (n = 2220) at 3-y intervals. The cIMT of the common carotid artery (CCA) and bifurcation segment were measured by B-mode ultrasound every 3 y, and the progressions of cIMT ( ∆cIMT) were estimated using the regression method. RESULTS Multivariable linear mixed-effects models (LMEMs) and ANCOVA revealed that subjects with higher serum isoflavones tended to have lower increases of CCA-cIMT. The mean ± SEM differences in 8.8-y ∆CCA-cIMT between extreme tertiles of serum isoflavones were -17.1 ± 8.4, -20.6 ± 8.3, and -23.3 ± 10.4 μm for daidzein, total isoflavone, and equol (P-trends < 0.05), respectively. LMEMs showed that the estimated yearly changes (95% CIs) (μm/y) in CCA-IMT were -2.0 (-3.8, -0.3), -1.9 (-3.6, -0.1), and -2.1 (-3.8, -0.3) in the highest (compared with the lowest) tertile of daidzein, genistein, and total isoflavones, respectively (P-interaction < 0.05). Path analyses indicated that the serum equol-atherosclerosis association was mediated by increased SHBG and decreased SBP. Similar beneficial associations were observed in the secondary analyses. CONCLUSIONS Serum isoflavones and equol exposure were associated with reduced cIMT progression, mediated by SHBG and SBP.

Abstract
BACKGROUND Capillary leak syndrome (CLS) is a rare disease characterized by profound vascular leakage and presents as a classic triad of hypotension, hypoalbuminemia and hemoconcentration. Severe CLS is mostly induced by sepsis and generally life-threatening in newborns, especially in premature infants. Continuous renal replacement therapy (CRRT) plays an important role of supportive treatment for severe CLS. Unfortunately, CRRT in preterm infants has rarely been well defined. CASE PRESENTATION We report the case of a 11-day-old girl with CLS caused by sepsis, who was delivered by spontaneous vaginal delivery (SVD) at gestational age of 25 weeks and 4 days, and a birth weight of 0.89 Kilograms(kg). The infant received powerful management consisting of united antibiotics, mechanical ventilation, intravenous albumin and hydroxyethyl starch infusion, vasoactive agents, small doses of glucocorticoids and other supportive treatments. However, the condition rapidly worsened with systemic edema, hypotension, pulmonary exudation, hypoxemia and anuria in about 40 h. Finally, we made great efforts to perform CRRT for her. Fortunately, the condition improved after 82 h' CRRT, and the newborn was rescued and gradually recovered. CONCLUSION CRRT is an effective rescue therapeutic option for severe CLS and can be successfully applied even in extremely-low-birth-weight premature.

Abstract
The molecular events that modulate the progression of monoclonal gammopathy of undetermined significance of the immunoglobulin M class (IgM-MGUS) to Waldenstrom Macroglobulinemia (WM) are mostly unknown. We implemented comparative proteomics and metabolomics analyses on patient serum samples to identify differentially expressed molecules crucial to the progression from IgM-MGUS to WM. Our data identified altered lipid metabolism as a discriminating factor between MGUS, WM, and matched normal controls. Levels of many fatty acids, including polyunsaturated fatty acids and dicarboxylic acids, were significantly downregulated in WM sera when compared to MGUS. These reductions were associated with diminished 15-LOX and PPAR protein expression and increased 5-LOX and GPX4 expression in WM versus MGUS patients’ samples. Furthermore, WM serum samples showed increased lipid peroxidation compared to MGUS. Treatment with IL-6 or TNFα, upstream regulators of differentially expressed proteins between MGUS and WM, increased lipid absorption and lipid peroxidation in WM cell lines. Knock-down of 15-LOX expression increased WM cell survival, an effect accompanied by increased 5-LOX and GPX4 expression. In summary, our data show that reduced fatty acid and lipid metabolite levels in the serum of the WM patients are associated with increased lipid peroxidation and that downregulation of 15-LOX increases the survival of WM cells. These data are highly significant in identifying the biomarkers of disease progression and designing targeted therapeutic intervention.

Abstract
The application of pit and fissure sealants is a well-established method to prevent and treat early childhood caries. Resin-based sealants with antibacterial properties provide additional benefits for caries prevention in a cariogenic oral environment. The objective of this study was to evaluate the effect of an antibacterial core-shell AgBr/cationic polymer nanocomposite (AgBr/BHPVP) on the properties of a resin-based pit and fissure sealant. A commercialized pit and fissure sealant without fluoride, Concise (3M, ESPE, USA), was used as the parent material and negative control. Experimental antibacterial sealants were formulated by the addition of AgBr/BHPVP nanoparticles at mass fractions of 0.5, 1.0, and 1.5 wt% to the parent material. A fluoride-releasing sealant, Clinpro (3M, ESPE), was used as the positive control. Bacterial colony-forming unit (CFU) counts, metabolic activity tests, field emission-scanning electron microscopy (FE-SEM), and confocal laser scanning microscopy (CLSM) observations were used to evaluate the antibacterial properties of AgBr/BHPVP-modified sealants against Streptococcus mutans before and after five months of aging. The Vickers microhardness, degree of conversion, and microleakage level of the sealants were also investigated. According to the results of CFU counts and metabolic tests, sealants containing AgBr/BHPVP showed better contact-killing bactericidal activity against S. mutans than the two commercial sealants, irrespective of aging conditions (both P < 0.05). The AgBr/BHPVP-modified sealants also showed a significant inhibitory effect on the planktonic S. mutans around the cured sealant surfaces. In addition, the Vickers microhardness, degree of conversion, and microleakage level of the parent material were not damaged by modification with AgBr/BHPVP (P > 0.05). AgBr/BHPVP-modified pit and fissure sealant with a dual bactericidal mechanism is a promising option for the prevention of pit and fissure caries.

Abstract
Objective: To investigate the clinical value of glypican-3 (GPC3) detection in the diagnosis and therapy-monitoring of primary hepatocellular carcinoma (HCC). Methods: From March 2018 to May 2019, the patients with HCC were enrolled as the experimental group(n=166)from Fudan University Shanghai Cancer Centre, while the specimens from health control group(n=94) and benign control group (n=50) were analyzed. The serum of GPC3 and alpha fetoprotein (AFP)levels were respectively detected by ELISA and chemiluminescence. GPC3 detections combined with AFP etc. in accuracy of HCC diagnosis were explored by using Logistic regression analysis. Results: The serum GPC3 level in patients with HCC [0.210 (0.048, 0.801)mg/L] [Median (quartile Q1, Q3)] was significantly higher than those in healthy controls [0.029(0.019, 0.052)mg/L] and benign controls [0.033(0.021, 0.043) mg/L] (Z=-7.69, P<0.001).The serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT) and AFP were significantly different among the three groups (Z=-7.02, -6.85, -8.36 respectively, P<0.001). Among the serological indicators, it was related to ALT and AST (Z=-3.77, -4.09 respectively, P<0.001).The Cut-off level of GPC3 was determined as 0.077 mg/L by ROC curve. The sensitivity of the combined detection of serum GPC3 with AFP for HCC was up to 87.82%, the specificity was 77.86%, the negative predictive value was 84.29%, and the positive predictive value was 82.53%.The HCC-GPC3 model was constructed by using Logistic regression analysis. The area under the ROC curve was 0.882, the total sensitivity was 91.10%, and the total specificity was 72.73%. Further analysis showed that the serum GPC3 of patients with HCC was significantly lower [0.454(0.019, 0.286) mg/L] than that before surgery[0.608(0.039, 0.554)mg/L](Z=-7.32, P<0.001). Conclusion: The detection of serum GPC3 can be applied to aid diagnosis and therapy-monitoring of HCC.The combination of GPC3 and AFP can improve the diagnostic efficiency of HCC.

Abstract
Objective: This study aimed to investigate the potential value of circumferential resection margin (CRM) in colon cancer prognostics. Summary Background Data: CRM has been extensively studied as an important prognostic factor in rectal and esophageal cancer, but not in colon cancer. Methods: Data from 6,681 CRM-positive patients and 25,908 CRM-negative patients diagnosed with colon cancer in 2010–2015 were obtained from the Surveillance, Epidemiology, and End Results database. Statistical analysis methods utilized included the chi-square test, Kaplan-Meier estimates, Cox proportional, and X-tile software analyses. Results: After propensity score matching, CRM positivity was found to be negatively related with survival (P < 0.001). X-tile software identified 0 and 30 mm as optimal cutoff values (P < 0.001) for prognosis, which was applicable only in stage II–IV patients. A 20 and 33% risk decrease were observed in patients with CRM between 0 and 30 mm [95% confidence interval (CI) = 0.76–0.84], and larger than 30 mm (95% CI = 0.62–0.71), respectively. Chemotherapy strongly benefited prognosis with a hazard ratio of 0.36 (95% CI = 0.34–0.38) for overall survival (OS). Patients with a CRM value of 0–30 mm seemed to benefit most from chemotherapy compared with other groups. CRM and number of regional lymph nodes are independent risk factors, and the latter is a good substitute for CRM in AJCC stage I patients. Conclusion: CRM positivity is a strong unfavorable survival indicator for colon cancer patients. A better outcome is expected with CRM values larger than 30 mm. This cutoff value only applied to stage II–IV patients. For stage I patients, number of regional lymph nodes is a good substitute to predict survival. Chemotherapy was another favorable prognostic factor, especially for patients with a CRM value between 0 and 30 mm.

Abstract
BACKGROUND The total and specific types of polyunsaturated fatty acids (PUFAs) related to metabolic syndrome (MetS) remain inconsistent. OBJECTIVE We assessed the association of erythrocyte n-3 and n-6 PUFAs with MetS and the components of MetS in a cohort population. METHODS This prospective analysis included 2754 participants (aged 40-75 y) from the Guangzhou Nutrition and Health Study (2008-2019) in China. Erythrocyte PUFAs at baseline were measured using gas chromatography. MetS was assessed every 3 y according to the updated National Cholesterol Education Program Adult Treatment Panel III criteria. Multivariable Cox proportional hazard models were used to evaluate HRs and 95% CIs. RESULTS We identified 716 incident cases of MetS. The primary analyses showed that the HRs (95% CIs) of MetS (tertile 3 versus 1) were 0.67 (0.56, 0.80) for n-3 PUFAs and 0.70 (0.58, 0.85) for n-6 PUFAs (all Ps trend <0.001). The secondary outcomes showed that, higher erythrocyte very-long-chain (VLC) PUFAs [20:3n-3, docosapentaenoic acid (DPA), docosahexaenoic acid (DHA), arachidonic acid (ARA), and 22:4n-6], but lower α-linolenic acid (ALA) and γ-linolenic acid (GLA), tended to be associated with lower incidences of MetS and its components; among individual MetS components, the associations of PUFAs were more pronounced for hypertriglyceridemia (HTG) and hypertension, followed by low high-density lipoproten (HDL) cholesterol. Significantly higher concentrations of n-3 PUFAs (total, DPA, and DHA) and n-6 PUFAs (total, ARA, and 22:4) were observed in participants with improved (versus progressed) status of MetS (all Ps trend ≤0.003). CONCLUSION This study reveals that higher erythrocyte VLC n-3 and n-6 PUFAs, but lower 18-carbon PUFAs (ALA and GLA), are associated with lower risks of MetS components (HTG, hypertension, and low HDL cholesterol) and thereby lower MetS incidence in Chinese adults.

Abstract
BACKGROUND Mucinous adenocarcinoma (MC) is a rare histological subtype of colorectal adenocarcinoma. Previous studies investigating the prognosis of MC have conflicting results and the proper treatment of MC remains unclear. METHODS This retrospective study presents the clinicopathological characteristics and prognosis of MC. This cohort study collected data from April 1 through August 01, 2018. This study used data on 107,735 patients with nonmucinous adenocarcinoma (NMC) and 9,494 with MC between 2009 and 2013 from the Surveillance, Epidemiology, and End Results program (SEER). Clinicopathological features were analyzed by chi-square test and survival curves by the Kaplan-Meier method. We used propensity score matching (PSM) to account for potential bias. Logistic regression and Cox proportional hazards models were used to compare and calculate adjusted risks of MC death. RESULTS MC was more frequent in patients with older age, large tumor size and moderate tumor grade compared with NMC (P<0.001). Five-year survival was lower for MC patients than NMC patients (P<0.001). Older age, later tumor node metastasis (TNM) stage and multiple tumors indicated a poorer prognosis while surgery gave better survival outcomes [hazard ratio (HR) =0.38; 95% confidence interval (CI), 0.33 to 0.44; P<0.001]. Younger age, left-side colon location and early disease stage were associated with better survival after surgery (P<0.001). CONCLUSIONS Age, TNM stage, tumor number and treatment were indicators of prognosis and surgery gave better survival for MC patients compared with those without surgery. Our study contributes to their clinical treatment.

Abstract
Objective:The study aimed to investigate the role of nuocytes in allergic rhinitis (AR) murine models. Method:After intranasal administration of recombinant (rm) interleukin (IL)-33 in BALB/c mice, nuocytes were sorted and purified from the mouse nasal-associated lymphoid tissue (NALT). Then, we examined the response of nuocytes to rmIL-33 in vitro. After a murine model of AR was established using ovalbumin, we adoptively transferred the cultured NALT-derived nuocytes to mice models, and determined allergic responses in them. Result:rmIL-33 expanded nuocytes in NALT of mice compared with AR mice (t=3.66, P<0.01), and increased production of IL-13 from these cells in vitro in comparison with unstimulated nuocytes (t=19.90, P<0.000 1). After adoptive transfer of nuocytes, sneezing (t=9.89, P<0.000 1) ,numbers of eosinophils(t=8.17, P<0.000 1), concentrations of IL-13 (t=40.47, P<0.000 1) and IL-33 (t=19.89, P<0.000 1) in nasal lavage fluid were all enhanced when compared with AR mice. Conclusion:Nuocytes promote allergic inflammation in a murine model of AR.

Abstract
Atypical porcine pestivirus (APPV), a newly discovered member of the genus Pestivirus, is considered to be associated with congenital tremors (CT) in piglets. From June 2016 to January 2018, 440 serum and tissue samples from CT-affected piglets in Anhui, Guangdong and Guangxi provinces were collected to detect APPV. The results showed a high level of 63.4% preference for APPV in 27 swine farms and complicated co-infection cases between APPV and other 12 swine viruses. Meanwhile, 12 novel APPV genomes were screened and identified. Results showed that complete genomes, Npro and NS5A genes of these novel 12 APPV sequences revealed 80.5%-99.8%, 78%-100% and 76.9%-99.8% nucleotide identities, respectively. Phylogenetic analyses based on sequences of full-length genomes, Npro and NS5A genes of APPV indicated three well-defined clades including a newly emerging branch in China. This study provides novel epidemiological information of APPV in China.

Abstract
PURPOSE Many studies have examined the association of isoflavone intake with type 2 diabetes (T2D), and produced inconsistent results. Few studies, however, explored the association using objective biomarkers (particular for daidzein metabolite-equol) of isoflavones. We aimed to explore the association of urinary equol, daidzein and genistein concentrations with T2D and examine the mediating roles of high-sensitivity C-reactive protein (hsCRP) and retinol binding protein 4 (RBP4). METHODS This prospective study included 2818 subjects. Urinary concentrations of equol, daidzein and genistein were measured by high-performance liquid chromatography-tandem mass spectrometry. The associations between urinary isoflavones and T2D incidence were evaluated by cox proportional hazards model. RESULTS After adjustment for covariates, urinary equol except daidzein and genistein was inversely associated with T2D incidence. In comparison with the first tertile, multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (95% CIs) for T2D incidence in the second and third tertile of equol concentration were 0.52 (0.37, 0.73) and 0.72 (0.53, 0.97), respectively. In stratified analyses by sex, the HR (95% CI) of men in the second vs. first tertile of equol was 0.29 (0.14, 0.58). Equivalent estimation in women was 0.67 (0.45, 1.01). Neither women nor men in the third tertile showed significant difference of T2D incidence compared with the first tertile. In path analyses, there was no evidence of mediating effects of hsCRP and RBP4 on the "equol-T2D" relationship. CONCLUSIONS Urinary equol was favorably associated with a decreased T2D incidence in Chinese adults. The equol-T2D relationship might not be mediated by hsCRP and RBP4. TRIAL REGISTRATION This study has been registered at http://www.clinicaltrials.gov as NCT03179657.

Abstract
Objective: To study the spatial and temporal mode of infectious TB transmission in Guangxi Zhuang Autonomous Region (Guangxi). Methods: Data related to infectious TB case (Include smear and/or culture positive patients) in Guangxi were collected from the National Notifiable Disease Reported System (NNDRS) from 2010 to 2015. Spatial-temporal analysis and prediction were performed by SaTScan 7.0.2, GeoDa 1.8.12, R program v 3.3.1 and SPSS 19.0 software, using the time series model, Moran's I global and local spatial autocorrelation (Empirical Bayes adjustment). Kulldorff 's space-time scan statistics displayed by R software was used to identify the temporal and spatial trend of TB. Results: The total number of infectious TB cases, collected from NNDRS was 76 151, and showing a decreasing trend on annual incidence (value of Chi-square for Linear trend=3 464.53, P-value=0.000). The forecast value of TB cases in 2016 was 7 764 (4 971-10 557), with peak in March, analyzed through the Winters'multiplicative model. The Moran's I global Statistics was greater than 0 (0.257-0.390). TB cluster seemed to have been existed for several years. The most significant hot spots seemed to be mainly located in the central and western parts of Guangxi, shown by local spatial autocorrelation statistics and the result from space-time scanning.Counties or districts that located in the east parts of Guangxi presented the low-low relation (significant cold spots). The situation of infectious TB seemed migratory. Conclusions: Our data showed an annual decreasing trend of incidence on infectious TB with temporal concentration in spring and summer. Main clusters (hot spots) were found to be located in the central and western parts of Guangxi. Hopefully, our findings can provide clues to uncover the real mode of TB transmission at the molecular-biological level.

Abstract
Objective: To investigate the prevalence and associated risk factors of diabetes and prediabetes in Blang ethnic adults in Menghai county. Methods: A cross-sectional survey including 3 365 Blang ethnic adults (aged 18 and above from 5 administrative villages) was conducted from February 2017 to March 2017 in Menghai county. A questionnaire, physical examination, and blood assays were included in the survey. Finally, a total of 3 237 adults with complete data were selected into this analysis. Results: The standardized prevalence of diabetes and prediabetes in Blang ethnic adults were estimated based on the sixth national census in 2010. According to the 1999 WHO criteria, the overall standardized prevalence of diabetes and prediabetes were 8.5% (men: 10.2%, women: 6.8%) and 16.1% (men: 18.0%, women: 14.1%), in which the standardized prevalence of newly diagnosed diabetes among the total population was 7.3% (men: 8.7%, women: 5.8%). Multivariable multinominal logistic regression analyses showed that age, hypertension, hypertriglyceridemia, and central obesity were significantly positively associated with both diabetes and prediabetes, with the corresponding odds ratios of 1.74 and 1.37, 2.39 and 2.02, 2.30 and 1.34, 2.55 and 1.73, respectively. Conclusion: The prevalence of diabetes is relatively high in Blang ethnic adults in Menghai county. Improving knowledge of diabetes among the local population is one of key steps in the prevention of diabetes.

Abstract
Objective: To investigate the therapeutic effects and mechanisms of interleukin-10 (IL-10) gene-modified dendritic cells (DC-IL-10) in mice with liver fibrosis. Methods: DC-IL-10 was constructed in vitro, the phenotype and function of which were evaluated by flow cytometry. BALB/c mice were treated with intraperitoneal injection of carbon tetrachloride (CCl4) to establish liver fibrotic model. DC-IL-10 was administrated via tail vein. Animals were divided into 4 groups including normal dendritic cell(DC) control, liver fibrosis only, negative lentiviral transfection DC (DC-mock) and DC-IL-10. Liver function, cytokine secretion, T lymphocyte differentiation and liver histomorphology were tested. Real-time PCR and western blot were used to analyze the effect of DC-IL-10 on Wnt/β-catenin signaling pathway and its role in liver fibrosis. Results: When compared with DC control and DC-mock, the expression of DC-IL-10 surface stimulating molecules (major histocompatibity complex-Ⅱ, CD(80), CD(86)) were significantly decreased (F=14.708, 22.503, 12.595, respectively, all P<0.05), and DC-IL-10 significantly inhibited T lymphocyte proliferation (F=50.295, P<0.05). When compared with liver fibrosis group, serum alanine aminotransferase and aspartate transaminase were decreased in DC-IL-10 treated group (all P<0.05), other parameters including inflammatory factors (tumor necrosis factor α, IL-6, IL-1β) reduced (all P <0.05), the proportion of regulatory T cells (Treg) increased (F=6.742, P<0.05), pathological damage improved, the expression of Wnt3a, α-SMA and β-catenin mRNA and protein significantly reduced in DC-IL-10 treatment group (all P<0.001) . Conclusions: DC-IL-10 induces elevation of Treg for immune tolerance, as well as inhibition of inflammatory response, block of Wnt/β-catenin signaling pathway, which translates into improvement of liver fibrosis.

Abstract
Objective:The aim of this study is to examine whether nuocytes induced differentiation of primary T cells into Th2 cells in AR mice in vitro. Method:A murine model of AR on the background of BALB/c was established using ovalbumin, and nuocytes were sorted and purified from the mouse nasal associated lymphoid tissue (NALT) and cultured in vitro. Then, we assessed the expression of IL-4 in these cells. Mouse peripheral blood mononuclear cells were isolated and Th2 cells and T cells were isolated for in vitro culture, and the percentage of T cells in Th2 cells was detected. Then, NALT-derived nuocyte cells cultured in vitro were added to the above-mentioned mouse T cell culture medium for co-culture. Result:Numbers of sneezing, nasal rubbing and eosinophils in nasal lavage fluid were all enhanced in AR mice compared to normal ones. We used flow cytometry analysis to identify nuocytes from mice NALT as CD3CD4CD8CD19CD11bCD11cFcεR1 (lineage)-ICOS+, and also found that the cells expressed IL-4, and its protein and mRNA were all increased in AR mice versus normal mice. After nuocytes were co-cultured with T-cell cultures, we determined the percentage of Th2 cells in total T cells, and found that the percentage was increased significantly. Conclusion:nuocyte cells may induce the differentiation of primary T cells into Th2 cells in AR mice through IL-4 pathway.

Abstract
BACKGROUND Group 2 innate lymphoid cells (ILC2s) represent a new innate effector leukocyte population that mediates type-2 immune response. However, the contribution of ILC2s to allergic rhinitis (AR) is currently not well defined. OBJECTIVE To evaluate the potential existence and function of allergen-induced ILC2s in the experimental AR. METHODS We established a murine model of AR using ovalbumin (OVA) and aluminium hydroxide. The OVA-induced ILC2s were sorted and purified from the mouse nasal-associated lymphoid tissue (NALT). Then, we assessed ILC2s responses to mouse recombinant interleukin (rmIL)-25, anti-IL17RB antibody and CC chemokine ligand (CCL) 25 in the culture. After that, we adoptively transferred the NALT-derived ILC2s alone or plus rmIL-25 or anti-IL17RB antibody to the murine model of AR to investigate their role in the nasal allergic inflammation. RESULTS We showed that ILC2s could be induced by OVA in the NALT of AR model. They were induced to secrete IL-5 and IL-13 by rmIL-25, and blocking of IL17RB contributed to the decreased production of these cytokines in the culture. We found that CCL25 induced the NALT-derived ILC2s migration through CC chemokine receptor 9 on ILC2s in vitro. Numbers of sneezing and nasal rubbing as well as counts of invasive eosinophils were all enhanced after the adoptive transfer of cultured ILC2s in vitro. The expressions of IL-5, IL-13, IL-25 and CCL25 in the NLF of allergic mice were also increased. CONCLUSION These findings show that ILC2s play a proinflammatory role in the murine AR model, and also highlight ILC2s as a new target in the future AR therapy.

Abstract
Objective: To detect the effect of brain cytoplasmic RNA 1 (BCYRN1) on the proliferation and migration of airway smooth muscle cells (ASMCs) in rat model of asthma. Methods: Male SD rats were randomly divided into control group and asthma group (n=10 each). The ovalbumin (OVA) model was constructed in asthma group. Real time-qPCR was performed to detect the level of BCYRN1 in the ASMCs separated from the airway tissue of these rats. Then 2-(4-iodophenyl)-3-(4-nitrophenyl)-5-(2, 4-disulfophenyl)-2H-tetrazolium (WST-1) assay, roche real-time cell analyzer assay and Transwell cell migration assay were performed to detect the viability/proliferation and migration of ASMCs which were transfected with Ad-BCYRN1.Platelet-derived growth factor (PDGF)-BB was used to treat ASMCs to induce proliferation and migration, and the level of BCYRN1 was examined.The viability/proliferation and migration of ASMCs treated with PDGF-BB and transfected with si-BCYRN1 were detected. Inspiratory resistance and expiratory resistance were measured in rats with BCYRN1 knockdown.Briefly, rats were randomly divided into four groups: control (group A), sensitization + Ad-GFP (group B), sensitization + AdSM22α-siBCYRN1 (group C), control + Ad-SM22α-siBCYRN1 (group D) (n=10 each). The corresponding adenovirus vectors were sent to lung of group B, group C and group D through nasal spray. The OVA model was constructed in group B and group C. The rats in group A and group D were treated with saline.After 24 h of the last treatment with OVA or saline, rats of each group were given tracheal intubation, connected with breathing machine. Rats were injected with methacholine to measure the inspiratory resistance and expiratory resistance. Results: The level of BCYRN1 in ASMCs separated from rats in asthma group and in ASMCs treated with PDGF-BB was 3.60±0.45 and 3.53±0.35, respectively, significantly higher than those of the corresponding control (both P<0.01). Ad-BCYRN1 significantly increased the expression of BCYRN1 in ASMCs. The cell viability and proliferation rates of ASMCs transfected with Ad-BCYRN1 increased 1.75-and 1.47-fold compared to those of the control group, respectively (P<0.01); mobility increased 2.42-fold compared to that of the control group (all P<0.01). BCYRN1 knockdown reversed the increasing proliferation and migration of ASMCs induced by PDGF-BB. The cell proliferation rate and cell migration number in the PDGF-BB treatment group were (4.87±0.21)% and 80.00±5.00, respectively, which were significant higher than those in the si-BCYRN1 transfected group ((3.63±0.21)% and 25.33±2.52, all P<0.01). BCYRN1 knockdown reduced the inspiratory resistance and expiratory resistance in sensitization + Ad-SM22α-siBCYRN1 group. When the concentration of acetylcholine reached 1 mg/kg, the inspiratory resistance in the group A, group B, group C, and group D were 8.27±0.21, 25.40±0.56, 12.07±0.67 and 8.40±0.46 cmH2O·s·ml-1, and expiratory resistance were 13.30±0.56, 38.37±1.33, 16.40±0.56 and 13.40±0.46 cmH2O·s·ml-1, respectively (all P<0.01). Conclusion: Overexpression of BCYRN1 promotes the proliferation and migration of ASMCs in rat model of asthma.

Abstract
OBJECTIVE To summarize and report the clinical characteristics and laboratory results of a case and those reported in literature with MHC class Ⅱ deficiency. METHOD The clinical features, laboratory results and gene mutation analysis of an infant with MHC class Ⅱ deficiency, who was diagnosed and treated in Peking Union Medical College Hospital since December 2013, were retrospectively analyzed."Major histocompatibility complex class Ⅱ deficiency"or"bare lymphocyte syndrome"were used as keywords in order to retrieve reports from CNKI (from its establishment to October 2015) and Wanfang Database (from its establishment to October 2015), PubMed Database (from its establishment to October 2015) was searched. The characteristics, diagnosis, treatment and prognosis were summarized by reviewing related articles. RESULT The patient was a 8-month-old boy. Since the fourth month of life, he started to have repeated fever, susceptible to a variety of pathogens, immune hemolytic anemia, severe malnutrition, and finally diagnosed as MHC class Ⅱ deficiency disease when he was 20-month-old.No related reports were retrieved from CNKI and Wanfang database, there were 20 articles and 179 patients were reported worldwide in the past 10 years. Patients exhibit an extreme vulnerability to infections(resptratory infection(82%, 146/178), inpection of gastroin testinal(76%, 135/178)). The common laboratory examinations showed hypogammaglobulinemia, CD4(+) lymphopenia(93%, 107/115) etc. Diagnosis relies on the flow-cytometric analysis and genetic analysis. CONCLUSION It is considered necessary for patients with young onset age, manifestation of clinically opportunistic infection as immune deficient disease, including the MHC class Ⅱ deficiency disease, especially long-term diarrhea, poor development and cryptosporidium infection. This disease could coexist with autoimmune disorders.

Abstract
BACKGROUND Chronic inflammation provides the substrate for various mechanisms involved in osteoporotic fracture. The Dietary Inflammatory Index (DII) could shed light on the effect of the inflammatory potential of the diet on osteoporotic hip fracture. OBJECTIVE This study tested the hypothesis that higher DII scores are associated with greater hip fracture risk in an elderly Chinese population. METHODS A 1:1 age- (±3 years), sex- and region-matched case-control study of 1050 pairs (female/male: 781/269) of elderly (age range = 52-83 years) Chinese was conducted in Guangdong, China (2009-2015). Cases were newly diagnosed (within 2 weeks) hip fracture patients and controls were recruited from either communities (n = 835 controls) or the hospital (n = 215). DII scores were calculated from self-reports using a validated 79-item food frequency questionnaire. Odds ratios (ORs) and their 95% confidence intervals (CIs) of the risk of hip fracture for DII scores were estimated from conditional logistic regression. RESULTS The multivariable-adjusted ORs (95% CIs) for hip fracture across quartiles of DII scores were 1 (reference), 1.42 (1.01, 1.99), 1.63 (1.16, 2.28), and 2.44 (1.73, 3.45) (P trend <.001). Comparing extreme quartiles, the adjusted ORs (95% CIs) for hip fractures were 2.08 (1.38, 3.12) for female and 4.30 (1.89, 9.80) for male participants, respectively (P interaction = .26). When stratified by the source of controls, a dose-response positive relationship was observed between DII scores and hip fracture risk among community-based controls but not those from the hospital (P interaction = .16). CONCLUSIONS A proinflammatory diet appears to be positively associated with hip fracture risk.

Abstract
Objective: To identify the clinical and immunological characteristics of pediatric antiphospholipid syndrome (APS) patients with pulmonary embolism. Method: Among 47 pediatric APS patients from Peking Union Medical College Hospital during the year of 2000 to 2015, 12 patients were diagnosed of pulmonary embolism, who were investigated and compared with APS patients without pulmonary embolism. Result: Twelve patients (among whom 6 cases were primary and the other 6 were secondary APS)had pulmonary embolism and all of them were non-shock type, which was the first presenting manifestation in 6 of them.Eight cases were misdiagnosed as infection, while 3 cases were missed.Among patients with pulmonary embolism, 10 patients suffered from deep vein thrombosis at the same time, mainly in lower extremities.2 cases had thrombotic recurrence, which happened only in primary APS patients, because of irregular monitoring of International Normalized Ratio, or not taking aspirin after quitting warfarin.Positive anticardiolipin (ACL) and lupus anticoagulant (LA) were found in 10 and 9 patients respectively.Four primary APS patients had positive anti-nuclear antibodies (ANA). During follow-up of 3-100 months (median 23 months) of primary APS, no one had evolved manifestations of systemic lupus erythematosus.Primary APS was more often seen in males (M∶F 5∶1 vs. 0∶6) and the patients were much younger ((15±1) vs. (17±0) years old) than those with secondary APS.Besides that, no statistically significant difference was seen between primary and secondary APS (P all>0.05). Compared with APS patients without pulmonary embolism, pulmonary hypertension was more common in patients suffered from pulmonary embolism (3/12 vs. 0, P<0.05). Conclusion: Pulmonary embolism can be the first symptom in pediatric APS patients and all of them are non-shock type, which tends to be misdiagnosed or missed. A majority of them suffer from deep vein thrombosis in the lower extremities.Rethrombosis takes place when the anticoagulant therapy is irregular.Positive anti-nuclear antibodies can be seen in primary APS patients, but no manifestations of lupus come out during follow-up.There is no significant difference between primary APS and secondary APS.Pulmonary hypertension is more common in APS patients suffered from pulmonary embolism.

Abstract
We conducted a case-control study to investigate the association between the interleukin-10 (IL-10) C819T polymorphism and susceptibility to gastric cancer in a Chinese population. A total of 157 patients with gastric cancer and 249 controls were consecutively enrolled from the Guizhou Provincial People's Hospital between October 2012 and February 2015. The polymerase chain reaction-restriction fragment length polymorphism technique was used to genotype for IL-10 C819T. As determined by χ2-test, there was a significant difference in genotype distributions of IL-10 C819T between gastric cancer patients and controls (χ2 = 7.09; P = 0.03). Based on unconditional logistic regression analysis, the TT genotype of IL-10 C819T was significantly associated with increased risk of gastric cancer when compared with that of the CC genotype [odds ratio (OR) = 2.24; 95% confidence interval (CI) = 1.17-4.26; P = 0.008]. In a dominant model, we found that the CT + TT genotype of IL-10 C819T was associated with susceptibility to gastric cancer compared to that of the CC genotype (OR = 1.63; 95%CI = 1.02-2.64). In a recessive model, the TT genotype of IL-10 C819T was correlated with a higher risk of gastric cancer when compared with that of the CC + CT genotype (OR = 1.75; 95%CI = 1.01-3.02). In conclusion, our study suggests that the IL-10 C819T polymorphism is associated with an increased risk of gastric cancer in co-dominant, dominant, and recessive models.

Abstract
OBJECTIVE To establish and evaluate the methods of internal quality control in blood donor screening by nucleic acid test (NAT). METHODS After HBV-DNA standard quality control (QC) sample (60 IU/ml) was diluted by pooling 6 samples, the concentration was 10.0 IU/ml, which was approach twice of the low limit. When the pooling result turned out reactive, the pooling samples need to be split into single sample to process. Meanwhile, the standard QC samples were tested as well. The same batch QC samples were tested 20 times respectively, calculate the mean (x̄), standard deviation (SD) and CV. Make Levey-Jennings QC curves by setting x̄±2SD as warning, x̄±3SD as rejected. The Levey-Jennings quality controls chart was mapped by using Microsoft Excel. RESULTS After 20 times test of mixed/split samples, the x̄±2SD were 33.03±1.47 and 30.08±0.98, the x̄±3SD were 33.03±2.20 and 30.08±1.47, the CV were 2.22% and 1.63%, respectively. The P value of t test was 0.08 and 0.17 respectively, there was no statistically significant difference between the 2 group. CONCLUSION When establish an internal QC system in the screening laboratory by nucleic acid testing, the concentration of the QC samples should be equal to normal specimens. This type of QC system may validate the extraction and amplification of the nucleic acid, and improve the stability of the test results.

Abstract
This study was purposed to understand the infection of HBV, HCV, HIV among the voluntary blood donors and the epidemic trend in infectious population in Chinese Nanjing area, and to guide the mobilization and recruitment of blood donors. A total of 199777 whole blood samples of voluntary blood donors were tested by ELISA, the nucleic acid technology (NAT) combined detection (HBV-DNA, HCV-RNA, HIV-RNA) was added for detection of the samples with HBsAg,anti-HCV, anti-HIV at least unilateral negative donors from June 10, 2010 to June 9, 2013 years, and these statistic data were analyzed. Every HIV reactive sample(HIV-antibody and/or HIV-RNA) was sent to be confirmed in the Centers for Disease Control and Prevention in Nanjing. The results showed that the voluntary donors' infection rate of HBsAg, anti-HCV, anti-HIV were 0.45%, 0.28%, 0.11% respectively; NAT positive rate was 0.07%, 32 cases were confirmed with anti-HIV positive, in which 30 cases were male (6 cases were repeated blood donors) and 2 cases were female, 3 cases were unconfirmed, in which 2 cases were males and 1 case was female. The statistical analysis demonstrated that the difference of unqualitative rate of HBsAg, anti-HCV, anti-HIV was statistically significant between the first-time and repeated blood donors.It is concluded that the positive rate of anti-HCV and anti-HIV displayed a declining trend year by year in Nanjing voluntary blood donation population from June 10,2010 to June 9, 2013 years. The unqualitative rate of HBsAg and NAT increased with the age increasing, while that of anti-HCV, anti-HIV decreased with age increasing. The unqualitative rate of the repeated blood donors is far lower than that of the first-time blood donors. The ELISA positive rate of anti-HIV testing in females is higher than that in males, but the confirmed positive rate of male is significantly higher than that of female. Therefore the consulting skills before donating should be improved, concerning the link of recruiting donors, focusing on strengthening the first-time donors' consultation, evaluating and developing the fixed voluntary blood donors, and vigorously popularizing NAT technology in blood screening to improve the blood safety effectively.

Abstract
Supercritical water oxidation (SCWO) of wastewater from an acrylic acid manufacturing plant has been studied on a continuous flow experimental system, whose reactor was made of Hastelloy C-276. Experimental conditions included a reaction temperature (T) ranging from 673 to 773K, a residence time (t) ranging from 72.7 to 339s, a constant pressure (P) of 25 MPa and a fixed oxidation coefficient (alpha) of 2.0. Experimental results indicated that reaction temperature and residence time had significant influences on the oxidation reaction, and increasing the two operation parameters could improve both degradation of chemical oxygen demand (COD) and ammonia nitrogen (NH3-N). The COD removal efficiency could reach up to 98.73% at 25 MPa, 773 K and 180.1 s, whereas the destruction efficiency of NH3-N was only 43.71%. We further carried out a kinetic analysis considering the induction period through free radical chain mechanism. It confirms that the power-law rate equation for COD removal was 345 exp(-52200/RT)[COD]1.98[O2]0.17 and for NH3-N removal was 500 exp(-64492.19/RT)[NH3-N]1.87 [O2]0.03. Moreover, the induction time formulations for COD and NH3-N were suspected to be exp(38250/RT)/173 and exp(55690/RT)/15231, respectively. Correspondingly, induction time changed from 2.22 to 5.38 s for COD and 0.38 to 1.38 s for NH3-N. Owing to the catalysis of reactor inner wall surface, more than 97% COD removal was achieved in all samples.

Abstract
The response of Peking ducks to supplements of Sophy β-glucan was studied. A total of 160 healthy 1-d-old mixed-sex ducklings were randomly allocated to 3 groups: Sophy β-glucan (n = 80), bacitracin zinc (n = 40), and control (n = 40), which received the same antibiotics-deficient diet supplemented with 1% β-glucan, 5% bacitracin zinc, or nothing, respectively. During 2 mo of the study, growth performance, carcass composition, and meat quality of Peking ducks were evaluated. Additionally, a separate immunological study was conducted with a total of 105 healthy male Peking ducks in 7 groups (n = 15) and immunized with different doses of β-glucan (0, 0.5, 2.5, 12.5, and 62.5 μg/duck) and BSA (200 μg/duck). Blood was taken for detection of anti-BSA-IgG antibody and peripheral blood mononuclear cells proliferation assays. Groups subjected to different dietary treatments showed almost no differences in growth performance and slaughter traits except breast muscle percentage and intestinal length. These 2 indicators were significantly higher in the bacitracin zinc group than in the control and β-glucan groups (P < 0.05). Similarly, chemical compositions, fatty acids, and amino acids of breast muscle were not significantly influenced by the diet. Ducks immunized with Sophy β-glucan did not have enhanced level of anti-BSA-IgG antibodies but had significant peripheral blood mononuclear cells proliferation compared with unchallenged ducks (P < 0.01). With an increase in the glucan concentration, the proliferative responses approximately linearly increased. These findings indicate that 1% Sophy glucan did not improve duck growth performance, carcass composition, and meat quality significantly under the conditions of the present experiment and mainly had regulatory or enhancing properties on poultry nonspecific cellular immunity.

Abstract
*White lupin (Lupinus albus) forms specialized cluster roots characterized by exudation of organic anions under phosphorus (P) deficiency. Here, the role of nitric oxide (NO) in P deficiency-induced cluster-root formation and citrate exudation was evaluated. *White lupin plants were treated with the NO donor sodium nitroprusside (SNP) and scavenger or inhibitor of NO synthase under conditions of P deficiency (0 muM) or P sufficiency (50 muM). *Phosphorus deficiency enhanced NO production in primary and lateral root tips, with a greater increase in cluster roots than in noncluster roots. NO concentrations decreased with cluster root development from the pre-emergent stage, through the juvenile stage, to the mature stage. The P deficiency-induced increase in NO production was inhibited by antagonists of NO synthase and xanthine oxidoreductase, suggesting the involvement of these enzymes in NO production. SNP markedly increased the number of cluster roots. Citrate exudation from different root segments in P-deficient roots was positively correlated with endogenous root NO concentrations. *These findings demonstrate differential patterns of NO production in white lupin, depending on root zone, developmental stage and P nutritional status. NO appears to play a regulatory role in the formation of cluster roots and citrate exudation in white lupin under conditions of P deficiency.

Abstract
BACKGROUND Congenital pulmonary lymphangiectasis (CPL) characterized by dilatation of pulmonary lymphatic vessels occurs as a congenital anomaly. With poor prognosis, neonatal presentation of bilateral CPL is associated with the severe compromise of pulmonary gas exchange and high mortality. METHODS A male infant born at 39 weeks of gestation was found to have CPL. Cyanosis and cardiac arrest occurred a few minutes after birth, and the symptoms remained after artificial ventilation. The infant died of hypoxemic cardiac failure 45 minutes after birth. Autopsy showed neither pleural effusion nor valvular abnormalities. RESULTS Microscopically dilated vessels with lymphatics were seen in the lung of the infant. Atelectasis, CPL, inhalation of amniotic fluid, partial hydropic degeneration of hepatic cells, and scrotal edema were diagnosed. CONCLUSION With regard to treatment and prognosis, CPL must be distinguished from interstitial emphysema and other diseases.

Abstract
Forty-three strains were screened from crude oil-contaminated samples by toluene and cyclohexane enrichment in medium. Ten of these strains demonstrated high protease activity on skim-milk agar. Among them, the PT121 isolate, identified as Pseudomonas aeruginosa, was selected based on its extracellular protease stability in the presence of hydrophilic organic solvents. The crude protease also retained most of its activity up to at least 14 days in the presence of various organic solvents at 50% concentration, and the protease activity in production medium was 10,876U/ml after 72h incubation. This protease showed high activity as a catalyst for aspartame precursor Cbz-Asp-Phe-NH2 synthesis in the presence of 50% dimethylsulfoxide (DMSO).
