Abstract
Objective: To investigate the clinicopathological features and immunophenotype of adult myofibroma with emphasis on its differential diagnosis. Methods: The clinical, pathologic data and immunohistochemical profiles were analyzed in 15 cases of adult myofibroma diagnosed between 2014 and 2020 in Department of Pathology, Fudan University Shanghai Cancer Center. The literature was reviewed. Results: There were seven males and eight females, with age at presentation ranging from 22 to 74 years (mean 54 years; median 57 years). Tumor occurred principally in the extremities (n=9), less frequently involved the head and neck region (n=3) and trunk (n=2); one case was located in the vertebral canal of C6-7. Fourteen cases were solitary; one case was multifocal. Most patients presented with a slowly growing painless subcutaneous nodule, about 1 to 2 cm in size. One patient with multifocal disease and the patient with spinal lesion complained of intermittent pain. The duration of symptoms ranged from 2 months to 10 years. Microscopically, they were well circumscribed. All cases showed biphasic growth pattern, consisting of relatively well-differentiated eosinophilic nodules alternating with dark-staining primitive-appearing areas. The light-staining hypocellular nodules were composed of myofibroblast-like plump spindle cells within an eosinophilic stroma, which assumed pale blue myxochondroid appearance and hyalinization of varying degree. The dark-staining areas were composed of compact short spindled to ovoid cells with hyperchromatic nuclei and low mitotic activity, frequently showing a distinctive hemangiopericytoma-like architecture. By immunohistochemistry, the myoid spindled cells and the primitive cells stained variably for α-SMA, MSA and calponin, but were consistently negative for desmin and β-catenin. Conclusions: Adult myofibroma tends to occur in the middle to old aged patients with a predilection for the dermis or subcutis of the extremities. It is a benign neoplasm which can be cured by excision in most cases. Familiarity with its distinctive clinicopathological features helps in the distinction from other myofibroblastic neoplasms.

Abstract
PURPOSE Whether Tsukushi (TSK) can protect against high-fat diet (HFD)-induced obesity and improve glucose metabolism remains controversial. Serum levels of TSK in the population have not been reported until now. We assessed the association among TSK level, TSKU genotype, and metabolic traits in humans. METHODS Associations between serum TSK levels and metabolic traits were assessed in 144 Han Chinese individuals. Loci in the TSKU gene region were further genotyped in 11,022 individuals. The association between the loci and serum TSK level was evaluated using the additive genetic model. The association between the loci and their metabolic traits in humans were also verified. RESULTS Lower TSK levels were observed in obese subjects than in control subjects (median and interquartile range 17.78:12.07-23.28 vs. 23.81:12.54-34.56, P < 0.05). However, in obese subjects, TSK was positively associated with BMI (β ± SE: 0.63 ± 0.31, P = 0.049), visceral fat area (β ± SE: 12.15 ± 5.94, P = 0.011), and deterioration of glucose metabolism. We found that rs11236956 was associated with TSK level in obese subjects (β 95% CI 0.17, 0.07-0.26; P = 0.0007). There was also a significant association between rs11236956 and metabolic traits in our population. CONCLUSIONS Our findings showed that serum TSK levels were associated with metabolic disorders in obese subjects. We also identified rs11236956 to be associated with serum TSK levels in obese subjects and with metabolic disorders in the total population.

Abstract
miRNAs are a class of hairpin‐derived RNAs, 21–24 nucleotides in length, which are involved in a range of biological processes. The bta‐miR‐2285 family has over 40 members spanning the entire bovine genome. We previously found that bta‐miR‐2285o‐3p was highly expressed in yak heart and lung when compared with cattle, which prompted us to investigate its potential function in high‐altitude adaptation of yaks. In this study, we detected wide‐spread high expression of bta‐miR‐2285o‐3p in yak tissues. Further experiments revealed that the protein tyrosine phosphatase receptor type M (PTPRM) gene was the host gene of bta‐miR‐2285o‐3p and that two linked SNPs in bta‐mir‐2285o precursor affected the biogenesis of mature miRNA (bta‐miR‐2285o‐3p). Functional analysis in vitro indicated that bta‐miR‐2285o‐3p attenuated hypoxia‐induced apoptosis by targeting very low‐density lipoprotein receptor (VLDLR), phosphatase and tensin homolog (PTEN) and caspase‐3. Expression level analysis in vivo revealed the high negative Pearson’s correlation between bta‐miR‐2285o‐3p and caspase3 in yak, highlighting the potential important roles of bta‐miR‐2285o‐3p in yak high‐altitude adaptation. Our study provides a typical model for deciphering the function of miRNAs in environmental adaptation.

Abstract
Objective: To elucidate the clinical characteristics of bloodstream infection in patients with allogeneic hematopoietic stem cell transplantation (allo-HSCT) in our hospital and improves the survival of transplant patients with bloodstream infection. Methods: Two hundred and ten patients with allo-HSCT from the Department of Hematology were retrospectively analyzed between October 2014 and September 2019. Pathogen distribution, drug resistance, risk factors, and outcomes were investigated in 49 allo-HSCT patients with bloodstream infections. Results: Forty-nine of 210 patients with allo-HSCT had bloodstream infection, and 59 pathogenic microorganisms were identified, mainly Gram-negative bacteria (67.8%) , of which E. coli had the highest incidence (23.7%) , CRO accounted for 42.5%, and Grampositive bacteria accounted for 23.7% (without vancomycin or linezolid-resistant strain) . Additionally, fungi accounted for 8.5%. Univariate analysis suggested that the risk factors of bloodstream infection were gender, pretransplant disease status, and conditioning regimen. In contrast, multivariate analysis showed that bloodstream infection was mainly related to conditioning regimens. Further grouping results showed that 77.6% of patients with neutropenia had bloodstream infections, and 22.4% of patients with non-neutropenia had bloodstream infections; 81.0% of patients with active infections before transplantation had bloodstream infections, while bloodstream infection occurred in 16.9% of patients without active infection. Survival analysis showed that long-term survival of patients with bloodstream infection is shorter than that of patients without bloodstream infection and long-term survival of patients with CRO infection is shorter than that of patients without CRO infection. The survival of patients with neutropenia longer than 14 d is shorter than that of patients with neutropenia shorter than 14 d. Furthermore, there is no correlation between whether there is an active infection before transplantation and whether they are in a neutropenic state at the time of infection and survival. Conclusion: Our results suggest that effective prevention of bloodstream infections from drug-resistant bacteria, particularly CRO, shortening the duration of neutropenia, eradication of potential infections before transplantation, and patient-adaptive conditioning could reduce transplant-related mortality and improve prognosis.

Abstract
Abstract
Background
Sarcoidosis is a systemic granulomatous disease with cardiac involvement reported in 20–27% of patients [1]. Cardiac sarcoidosis (CS) can lead to atrial or ventricular arrhythmias, various conduction system disorders, heart failure or sudden cardiac death, depending on the location of myocardial involvement [2]. Previous studies have investigated the possible types of CS based on the distribution of myocardial involvement on imaging as well as the role of genetic factors [3,4]. However, there are no studies describing the clinical heterogeneity of CS patients.
Purpose
In order to determine if clinical clusters exist in CS, we carried out a latent class analysis (LCA) to explore potential phenotypes in a large sample of CS patients from the National Inpatient Sample (NIS).
Methods
We identified 848 patients with a diagnosis of CS from the NIS in 2016–2018. A LCA was performed based on comorbidities. Utilizing the Bayesian information criterion and Akaike's information criterion we divided our study population into 3 cohorts. We subsequently applied the LCA model for our study population to fit each patient into one of the 3 cohorts. Finally, we compared the clinical outcomes among the 3 groups.
Results
Following LCA, patients in cohort 3 were strongly associated with a cardiometabolic syndrome profile with the highest prevalence of congestive heart failure (CHF, 95.1%), chronic kidney disease (CKD, 69.7%), diabetes mellitus (68.9%), hyperlipidemia (52.5%) and obesity (45.1%). Patients in cohort 2 had an intermediate prevalence of cardiometabolic syndrome with a universal diagnosis of hypertension (100%) but with the lowest number of CHF (32.5%) patients and none with CKD. Finally, patients in cohort 1 had the least comorbidities in comparison to the other groups but there was a higher prevalence of CHF (71.7%). There was no significant difference in mortality among the 3 groups, but acute respiratory failure was the highest in cohort 3. However, ventricular arrhythmias were more prevalent in cohort 1 patients (Table).
Conclusion
We identified 3 different types of CS based on their clinical phenotype. The clinical outcomes varied among the cohorts with ventricular arrhythmias being the most prevalent in patients with the least cardiometabolic comorbidities.

Abstract
The associative effects resulting from the proportions of neutral detergent fibre (NDF) and non fibre carbohydrate (NFC) were explored and assessed by in vitro gas production . Total mixed rations (TMR) composed primarily of alf a lfa and corn soybean concentrate were fed to growing cashmere goats. Treatments were defined by three proportions of NFC and NDF namely 2.00 ( TMR1), 2.35 ( TMR2), and 3.00 ( that were used to grow cashmere goats , and these TRMs were incubated for 48 h ours to evaluate their influence on associative effects. The results indicated that the associative influences of these treatments on gas production occurred within the cultures predominantly at 2 8 hours, and disappeared gradually as culture time was ex tended . TMR 2 and TMR3 incubation increased gas production compared with that observed in the other groups at all incubation times P > 0.05), and these groups exhibited positive associative effects, particularly during the early hours of incubation P <0.05 )). TMR 3 displayed the best associative effect.

Abstract
Acrolein, an electrophilic α,β-unsaturated aldehyde, is present in foods and beverages, and is a product of incomplete combustion, and thus, reaches high ppm levels in tobacco smoke and structural fires. Exposure to acrolein is linked with cardiopulmonary toxicity and cardiovascular disease risk. The hypothesis of this study is the direct effects of acrolein in isolated murine blood vessels (aorta and superior mesenteric artery, SMA) are transient receptor potential ankyrin-1 (TRPA1) dependent. Using isometric myography, isolated aorta and SMA were exposed to increasing levels of acrolein. Acrolein inhibited phenylephrine (PE)-induced contractions (approximately 90%) in aorta and SMA of male and female mice in a concentration-dependent (0.01-100 μM) manner. The major metabolite of acrolein, 3-hydroxypropylmercapturic acid (3HPMA), also relaxed PE-precontracted SMA. As the SMA was 20× more sensitive to acrolein than aorta (SMA EC50 0.8 ± 0.2 μM; aorta EC50 > 29.4 ± 4.4 μM), the mechanisms of acrolein-induced relaxation were studied in SMA. The potency of acrolein-induced relaxation was inhibited significantly by: 1) mechanically-impaired endothelium; 2) Nω-Nitro-L-arginine methyl ester hydrochloride (L-NAME); 3) guanylyl cyclase (GC) inhibitor (ODQ); and, 4) a TRPA1 antagonist (A967079). TRPA1 positive immunofluorescence was present in the endothelium. Compared with other known TRPA1 agonists, including allyl isothiocyanate (AITC), cinnamaldehyde, crotonaldehyde, and formaldehyde, acrolein stimulated a more potent TRPA1-dependent relaxation. Acrolein, at high concentration [100 μM], induced tension oscillations (spasms) independent of TRPA1 in precontracted SMA but not in aorta. In conclusion, acrolein is vasorelaxant at low levels (physiological) yet vasotoxic at high levels (toxicological).

Abstract
Objective: To study the risk factors of adverse pregnancy outcomes for induced abortion of cesarean scar pregnancy in midtrimester. Methods: A national multicenter retrospective study was conducted. A total of 154 singletons pregnant women with cesarean scar pregnancy during the second trimester induced abortion by various reasons in 12 tertiary A hospitals were selected, their pregnant outcomes were observed and the risk factors of serious adverse outcomes were analyzed with univariate and multivariate logstic regression; the role of ultrasound and MRI in predicting placenta accreta and severe adverse outcomes was evaluated, the effectiveness of uterine artery embolization (UAE) in preventing hemorrhage in pregnant women with and without placenta accreta was compared. Results: Among 154 subjects, the rate of placenta accreta was 42.2% (65/154), the rate of postpartum hemorrhage≥1 000 ml was 39.0% (60/154), the rate of hysterectomy was 14.9% (23/154), the rate of uterine rupture was 0.6% (1/154). The risk factor of postpartum hemorrhage≥1 000 ml and hysterectomy was placenta accreta (P<0.01). For each increase in the number of parity, the risk of placenta accreta increased 2.385 times (95%CI: 1.046-5.439; P=0.039); and the risk of placenta accreta decreased with increasing ultrasound measurement of scar myometrium thickness (OR=0.033, 95%CI: 0.001-0.762; P=0.033). The amount of postpartum hemorrhage and hysterectomy rate in the group with placenta accreta diagnosed by ultrasound combined with MRI were not significantly different from those in the group with placenta accreta diagnosed by ultrasound only or MRI only (all P>0.05). For pregnant women with placenta accreta, there were no significant difference in the amount of bleeding and hysterectomy rate between the UAE group [median: 1 300 ml; 34% (16/47)] and the non-embolization group (all P>0.05); in pregnant women without placenta accreta, the amount of bleeding in the UAE group was lower than that in the non-embolization group (median: 100 vs 600 ml; P<0.01), but there was no significant difference in hysterectomy rate [2% (1/56) vs 9% (3/33); P>0.05]. Conclusions: (1) Placenta accreta is the only risk factor of postpartum hemorrhage≥1 000 ml with hysterectomy for induced abortion of cesarean scar pregnancy in midtrimester; multi-parity and ultrasound measurement of scar myometrium thickness are risk factors for placenta accreta. (2) The technique of using ultrasound and MRI in predicting placenta accreta of cesarean scar pregnancy needs to be improved. (3) It is necessary to discuss of UAE in preventing postpartum hemorrhage for induced abortion of cesarean scar pregnancy in midtrimester.

Abstract
Abstract
Study question
Does repeated cryopreservation process effect embryo implantation potential and neonatal outcomes of human embryos?
Summary answer
Repeated cryopreservation impaired embryo implantation potential, resulting in a lower live birth rate and higher miscarriage rate, despite a comparable neonatal complication rate.
What is known already
With significant advances in the field of ART, the number of available embryos for transfer per cycle has also increased, resulting in a slew of surplus embryo cryopreservation. However, limited researches have focused on the embryonic development potential, clinical outcomes, pregnancy complications as well as the neonatal complications of embryos experiencing repeated cryopreservation.
Study design, size, duration
This was a retrospective, single-center cohort study. All ART cycles from January 2014 to December 2018. Age, body mass index, and number of oocytes retrieved were preferentially matched within a required range, with a total of 709 couples included in the study.
Participants/materials, setting, methods
The study was conducted in the Reproductive Medicine Centre affiliated to a university. Preferentially matched participants were divided into three groups according to the times of embryo cryopreservation: the fresh group (n = 249), the cryopreservation group (n = 244) and the re-cryopreservation group (n = 216). Embryo implantation rate, live birth rate, miscarriage rate, and neonatal complication rate were compared among these three groups.
Main results and the role of chance
The embryo implantation rate, clinical pregnancy rate and live birth rate in the re-cryopreservation group were significantly lower, and there was also a slight increase in the miscarriage rate. Logistic regression analysis indicated that embryos with repeated cryopreservation and lower TE scores were at higher risk of embryo implantation failure in single embryo transfer cycles (OR = 1.79 and 1.56 respectively). No significant differences were observed in gender, gestational age, birthweight, neonatal abnormality, and neonatal complications among the groups.
Limitations, reasons for caution
This was a retrospective cohort study conducted in single center. A multi-center prospective study with a larger sample size in well-matched participants is needed to reinforce our findings.
Wider implications of the findings: Our findings demonstrated the adverse effect of repeated cryopreservation on embryo implantation potential. To avoid embryo waste, or in some special circumstances such as re-biopsy in PGT cycles, an additional cryopreservation on embryos was considered to be available to achieve clinical pregnancy and live birth.

Abstract
OBJECTIVE The purpose of this study was to investigate the expression of miR-873-5p and long non-coding RNA X-inactive specific transcript (lncRNA-XIST) in myocardial infarction (MI), the interaction mechanism and the effect of target gene MCL1 on apoptosis in H9c2 cells. MATERIALS AND METHODS quantitative Real Time-Polymerase Chain Reaction (qRT-PCR) was used to detect and compare the expressions of miR-873-5p and lncRNA XIST in 8 myocardial infarction rats and 8 normal rats tissues, respectively, and the correlation between the expressions of miR-873-5p and lncRNA XIST in the myocardial tissues was explored. Next, qRT-PCR and Western blot were used to detect the effects of upregulation of miR-873-5p and downregulation of lncRNA XIST, as well as the impacts of their interactions on the expression level of MCL1 in H9c2 cells and the apoptosis of cells. RESULTS It was found that the downregulation of miR-873-5p protected the heart against apoptosis after AMI, and lncRNA XIST inhibited apoptosis in H9c2 cells after hypoxia. Besides, inhibiting lncRNA XIST could upregulate miR-873-5p and downregulate MCL1, thus increasing apoptosis in the H9c2 cells after hypoxia. CONCLUSIONS LncRNA XIST can regulate cardiomyocyte apoptosis by targeting miR-873-5p.

Abstract
OBJECTIVE The purpose of this study was to explore the influence of Ghrelin on myocardial injury of septic rats through the Janus kinase/signal transducer and activator of transcription (JAK/STAT) signaling pathway. MATERIALS AND METHODS A total of 36 Sprague-Dawley rats were randomly divided into normal group (n=12), model group (n=12), and Ghrelin group (n=12). The rats in the normal group were fed normally, while those in the model group were intraperitoneally injected with endotoxin to establish the sepsis model. The rats in the Ghrelin group were given intraperitoneal injection of Ghrelin solution to prepare the sepsis model. 9 h later, the specimens were obtained. Then, the expressions of interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) were detected via immunohistochemistry, and the protein expressions of phosphorylated JAK (p-JAK) and STAT3 were determined by Western blotting (WB). Next, enzyme-linked immunosorbent assay (ELISA) was performed to measure the content of IL-6 and TNF-α, and quantitative Polymerase Chain Reaction (qPCR) was applied to examine the messenger ribonucleic acid (mRNA) expressions of JAK and STAT3. Finally, the cell apoptosis was detected through terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) assay. RESULTS The results of immunohistochemistry showed that compared with those in the normal group, the positive expression levels of IL-6 and TNF-α were markedly increased in other groups (p<0.05), while in comparison with those in the model group, the positive expression levels of IL-6 and TNF-α were decreased significantly in the Ghrelin group (p<0.05). The WB results indicated that the model group and Ghrelin group had remarkably higher protein expression levels of p-JAK and STAT3 than the normal group (p<0.05), and Ghrelin group exhibited notably lower protein expression levels of p-JAK and STAT3 than the model group (p<0.05). According to the results of qPCR, the relative mRNA expression levels of JAK and STAT3 were distinctly raised in the model group and Ghrelin group in comparison with those in the normal group (p<0.05), while they were reduced evidently in the Ghrelin group compared with those in the model group (p<0.05). Furthermore, it was manifested in the results of ELISA that the model group and Ghrelin group had prominently elevated content of TNF-α and IL-6 compared with normal group (p<0.05), and Ghrelin group displayed significantly lowered content of TNF-α and IL-6 in comparison with the model group (p<0.05). Moreover, the TUNEL results revealed that the apoptosis rate was remarkably higher in the other two groups than that in the normal group (p<0.05), while it was evidently lower in the Ghrelin group than that in the model group (p<0.05). CONCLUSIONS Ghrelin can inhibit inflammatory response and apoptosis in the process of myocardial injury in septic rats by repressing the JAK/STAT signaling pathway.

Abstract
In Drosophila melanogaster, ecdysis triggering hormone (ETH) is the key factor triggering ecdysis behaviour and promoting trachea clearance. However, whether ETH plays the dual roles in non-dipteran insects is unknown. In this survey, we found that Ldeth mRNA levels were positively correlated with circulating 20-hydroxyecdysone (20E) titers in Leptinotarsa decemlineata. Ingestion of an ecdysteroid agonist halofenozide or 20E stimulated the transcription of Ldeth, whereas RNA interference (RNAi) of ecdysteroidogenesis (LdPTTH or LdSHD) or 20E signalling (LdEcR, LdUSP or LdFTZ-F1) genes inhibited the expression, indicating ETH acts downstream of 20E. RNAi of Ldeth at the final instar stage impaired pupation. More than 80% of the Ldeth-depleted beetles remained as prepupae, completely wrapped in the old larval cuticles. These prepupae became withered, dried and darkened gradually, and finally died in soil. The remaining Ldeth hypomorphs pupated and emerged as abnormal adults, bearing smaller and wrinkle elytrum and hindwing. Moreover, the tracheae in the Ldeth hypomorphs were full of liquid. We accordingly proposed that the failure of trachea clearance disenabled air-swallowing after pupa-adult ecdysis and impacted wing expansion. Our results suggest that ETH plays the dual roles, initiation of ecdysis and motivation of trachea clearance, in a coleopteran.

Abstract
AIM Diabetic retinopathy (DR) is a chronic disease causing health and economic burdens on individuals and society. Thus, this study is conducted to figure out the mechanisms of bone marrow mesenchymal stem cells (BMSCs)-induced exosomal microRNA-486-3p (miR-486-3p) in DR. METHODS The putative miR-486-3p binding sites to 3'untranslated region of Toll-like receptor 4 (TLR4) was verified by luciferase reporter assay. High glucose (HG)-treated Muller cells were transfected with miR-486-3p or TLR4-related oligonucleotides and plasmids to explore theirs functions in DR. Additionally, HG-treated Muller cells were co-cultured with BMSC-derived exosomes, exosomes collected from BMSCs that had been transfected with miR-486-3p or TLR4-related oligonucleotides and plasmids to explore their functions in DR. MiR-486-3p, TLR4 and nuclear factor-kappaB (NF-κB) expression, angiogenesis-related factors, oxidative stress factors, viability and apoptosis in HG-treated Muller cells were detected by RT-qPCR, western blot analysis, ELISA, MTT assay and flow cytometry, respectively. RESULTS MiR-486-3p was poorly expressed while TLR4 and NF-κB were highly expressed in HG-treated Muller cells. TLR4 was a target of miR-486-3p. Upregulating miR-486-3p or down-regulating TLR4 inhibited oxidative stress, inflammation and apoptosis, and promoted proliferation of HG-treated Muller cells. Meanwhile, BMSC-derived exosomes inhibited oxidative stress, inflammation and apoptosis, and promoted proliferation of HG-treated Muller cells. Restoring miR-486-3p further enhanced, while up-regulating TLR4 reversed, the improvement of exosomes treatment. CONCLUSION Our study highlights that up-regulation of miR-486-3p induced by BMSC-derived exosomes played a protective role in DR mice via TLR4/NF-κB axis repression.

The true incidence of chromosomal mosaicism after preimplantation genetic testing is much lower than that indicated by trophectoderm biopsy. Hum Reprod 2021; 36:1691-1701.

Abstract
STUDY QUESTION What is the true incidence of chromosomal mosaicism in embryos analyzed by preimplantation genetic testing (PGT). SUMMARY ANSWER The true incidence of chromosomal mosaicism is much lower than we usually surmise. WHAT IS KNOWN ALREADY In recent years, contemporary methods for chromosome analysis, along with the biopsy of more than one cell, have given rise to an increased rate of chromosomal mosaicism detection after preimplantation genetic testing for aneuploidy. However, the exorbitant incidence of mosaicism represents a dilemma and imposes restrictions on the application of PGT treatment. Concern has been raised about the possibility that the incidence of chromosomal mosaicism is overestimated and quite a few of the results are false-positive errors. However, studies verifying the diagnosis of chromosomal mosaicism and assessing the true incidence of chromosomal mosaicism are limited. STUDY DESIGN, SIZE, DURATION A total of 1719 blastocysts from 380 patients who underwent PGT treatment were retrospectively analyzed to evaluate the typical incidence of mosaicism. Then 101 embryos donated by 70 couples were re-biopsied and dissected into three portions if available: trophectoderm (TE), inner cell mass (ICM), and the remaining portions. All the portions were tested using next-generation sequencing (NGS), and the results were compared to the original diagnosis. PARTICIPANTS/MATERIALS, SETTING, METHODS The setting for this study was a university-affiliated center with an in-house PGT laboratory. All samples were amplified with multiple annealing and looping-based amplification cycles (MALBACs) and the NGS was carried out on a Life Technologies Ion Proton platform. MAIN RESULTS AND THE ROLE OF CHANCE A clinical TE biopsy revealed an incidence of 11.9% for diploid-aneuploid mosaicism (DAM), 17.3% for aneuploid mosaicism (AM) and 29.1% in total. After rebiopsy, 94.1% whole-chromosome aneuploidies and 82.8% segmental-chromosome aneuploidies were confirmed in the embryos. As for the mosaic errors, only 32 (31.7%) out of 101 embryos presented with uniform chromosomal aberrations in agreement with the original biopsy results, 15 (14.8%) embryos presented with de novo chromosomal aberrations, and 54 (53.5%) embryos showed a euploid profile in all portions. Among the 32 uniform embryos, the true mosaicism was confirmed in only 4 cases, where a reciprocal chromosomal aberration was identified; 14 embryos presented with identical mosaicism, providing the moderate evidence for true mosaicism; and 14 embryos displayed uniform full aneuploidies in all portions of embryo, revealing a high-grade mosaicism or a false-negative diagnosis. Logistical regression analysis revealed that the concordance rate with ICM was associated with the type and level of mosaicism. The concordance rate of segmental-chromosome mosaicism was significantly lower than whole-chromosome mosaicism (adjusted Odds Ratio (aOR): 5.137 (1.061, 24.876), P = 0.042) and compared to DAM, the concordance rate of AM was significantly higher (aOR: 6.546 (1.354, 31.655), P = 0.019). The concordance rate also increased with increasing levels of mosaicism (P < 0.001). LIMITATIONS, REASONS FOR CAUTION This study was limited by a small sample size and the use of a single whole-genome amplification (WGA) method and NGS platform. These findings are only applicable to samples subjected to MALBAC amplification and Ion Proton platform, and studies involving larger sample sizes and multiple WGA methods and NGS platforms are required to prove our findings. WIDER IMPLICATIONS OF THE FINDINGS TE biopsy is reliable to detect whole-chromosome aneuploidies, but the ability to diagnose mosaicism is doubtful. More attention should be paid to false-positive and false-negative errors in NGS-based PGT, especially for laboratories using less stringent criteria for mosaicism classification (i.e. 20-80%), which might be subject to a much higher false-positive mosaicism rate in the practice. STUDY FUNDING/COMPETING INTEREST(S) This study was supported by grants from the National Key R&D Program of China (No. 2016YFC1000206-5) and the National Natural Science Foundation of China (No. 81701509).

Abstract
OBJECTIVE The purpose of this study was to explore the changes in the expressions of micro ribonucleic acid (miR)-22-3p and matrix metalloproteinase-9 (MMP-9) in rats with thoracic aortic aneurysm (TAA) and their significance. MATERIALS AND METHODS A total of 16 specific pathogen-free Sprague-Dawley female rats were randomly divided into normal group (n=8) and angiotensin II (Ang II) group (n=8). Ang II was perfused using the micro pump in Ang II group, while the same amount of normal saline was perfused in the normal group. After continuous intervention, the tumor formation rate in the thoracic aorta was observed, and the expression of miR-22-3p was detected via Reverse Transcription-Polymerase Chain Reaction (RT-PCR) in both groups. Other 16 rats were selected and randomly divided into agomiR-22-3p group (n=8) and control group (n=8). In the agomiR-22-3p group, agomiR-22 and Ang II were continuously injected via angular vein. In the control group, agomiR negative control was injected, and Ang II was continuously perfused. After intervention for 4 weeks, the tumor formation rate in the thoracic aorta was observed, and the expression of MMP-9 was determined via immunofluorescence and immunohistochemistry in both groups. RESULTS After intervention for 4 weeks, the expression of miR-22-3p in Ang II group was significantly lower than that in normal group (p<0.05). After drug administration for 4 weeks, agomiR-22-3p group had a lower tumor formation rate (p<0.05) and a lower expression of MMP-9 than the control group (p<0.05). CONCLUSIONS The expression of miR-22-3p declines in TAA rats, and miR-22-3p can inhibit the expression of MMP-9, thus suppressing the formation of TAA in rats.

Abstract
OBJECTIVE To study the expression level of the long non-coding ribonucleic acid (lncRNA) KCNQ1 overlapping transcript 1 (KCNQ1OT1) in the patients with myelodysplastic syndrome (MDS), as well as the correlation between the expression level of lncRNA KCNQ1OT1 and the clinical diagnosis and prognosis of MDS. PATIENTS AND METHODS A total of 60 MDS patients were selected as the MDS group and 20 healthy people as the control group. The expression levels of lncRNA KCNQ1OT1 in the serum of the two groups of participants were compared. The associations of the expression level of lncRNA KCNQ1OT1 with the clinicopathological parameters of the MDS patients were analyzed. MDS was divided into various subtypes in accordance with the World Health Organization (WHO) classification. The expression level of lncRNA KCNQ1OT1 in all the subtypes was detected, and its correlation with the prognosis was judged. RESULTS There was a statistical difference in the expression level of lncRNA KCNQ1OT1 between the control group and the MDS group (p<0.001). The MDS patients with the low expression of lncRNA KCNQ1OT1 had remarkably longer survival and progression-free survival (PFS) in comparison with those with the high expression of lncRNA KCNQ1OT1 (p<0.001). The survival status and chemosensitivity of the MDS patients were closely related to the prognosis (p<0.001). CONCLUSIONS LncRNA KCNQ1OT1 presents high expressions in the MDS patients, indicating that it has a correlation with the prognosis of the MDS patients, and thus providing a new direction for the future treatment of the MDS patients.

Abstract
Objective: To analyze the results of liver cancer screening for urban residents in Zhejiang Province from 2013 to 2018 and explore the influencing factors of the detection rate. Methods: From September 2013 to August 2019, six urban communities in Hangzhou (Jianggan District and Gongshu District), Ningbo (Haishu District, Yinzhou District and Jiangbei District), and Quzhou (Kecheng District) were selected as study sites. All permanent residents aged 40-74 (with local household registration and living in the local area for more than 3 years) were selected as the research subjects by using cluster sampling method. Patients with confirmed cancers and other serious medical and surgical diseases were excluded. A total of 166 293 research subjects were included. Basic demographic characteristics and risk factors of subjects were obtained through questionnaire surveys. The cancer risk assessment system was used to evaluate the liver cancer risk of subjects. Clinical screening participation and screening results for subjects at high risk of liver cancer were obtained from participating hospitals. The high-risk rate of liver cancer, clinical screening rate, detection rate of positive lesions, and detection rate of suspected liver cancer were analyzed. Poisson regression was used to analyze the influencing factors of detection rate. Results: The age of 166 293 subjects was (56.01±8.40) years, of which 41.36% (68 777) were males. A total of 23 765 high-risk subjects for liver cancer were screened (the high-risk rate was 14.29%). Among them, a total of 12 375 subjects participated in clinical screening for liver cancer, with a screening rate of 52.07% (12 375/23 765). A total of 297 cases of positive lesions were detected and the detection rate was 2.40% (297/12 375). A total of 8 cases of suspected liver cancer were detected, with a detection rate of 0.06% (8/12 375). The results of multivariate Poisson regression model analysis showed that compared with men, people who never smoked, never ate pickled food, had low oil content, and had no history of hepatobiliary disease, female, people who were smoking or had smoked, sometimes ate pickled food, ate higher oil content, and had a history of hepatobiliary disease had a higher detection rate of positive lesions. The incidence rate ratio (IRR) (95%CI) values were 1.98 (1.45-2.70), 2.23 (1.61-3.09)/2.08 (1.31-3.28), 1.82 (1.22-2.70), 1.44 (1.08-1.91), and 1.45 (1.05-2.00), respectively. Compared with those aged from 40 to 49 years old and without HBsAg test, the IRR (95%CI) of suspected liver cancer in people aged 70 to 74 years old and HBsAg positive were 16.30 (1.32-200.74) and 6.43 (1.24-33.22), respectively. Conclusion: The urban cancer early diagnosis and early treatment project in Zhejiang Province has good compliance in clinical screening of liver cancer. Abdominal ultrasound examination and serum alpha-fetoprotein detection are helpful to detect liver cancer and its precancerous lesions in the high-risk population of liver cancer.

Abstract
OBJECTIVE To investigate the role of the differential piRNA NU13 derived from piwil2-induced cancer stem-like cells (piwil2-iCSCs) in regulating biological behaviors of Wilms tumor cells (G401). OBJECTIVE The expressions of piRNA NU13 and NOP56 were detected in Wilms tumor cell line G401 using RT-qPCR. G401 cells were transfected with piRNA NU13 mimics and inhibitor for its over-expression and inhibition, and the transfection efficiency was verified with RT-qPCR. The changes in proliferation of G401 cells after transfection were detected using CCK8 assay, and cell apoptosis was analyzed using flow cytometry. Wound healing assay and Transwell assay were performed to examine the changes in migration and invasion abilities of the transfected cells. The binding of NOP56 and piRNA NU13 was detected using dual luciferase experiment. The protein expressions of MMP2, MMP9, BAX, Bcl2, and NOP56 in the cells were detected with Western blotting. OBJECTIVE RTqPCR showed that the expression of piRNA NU13 decreased significantly in human Wilms tumor G401 cells as compared with that in renal tubular epithelial cell line HK2 (P < 0.05), and NOP56 was highly expressed in G401 cells and Wilms tumor tissues (P < 0.05). Over-expression of piRNA NU13 significantly suppressed the proliferation, migration and invasion of G401 cells, promoted cell apoptosis (P < 0.05), inhibited the expression of MMP2, MMP9 and Bcl2, and enhanced the expression of BAX (P < 0.05). The results of dual luciferase experiment showed that piRNA NU13 did not bind to NOP56 directly but regulated the expression of NOP56 in an indirect manner. OBJECTIVE piRNA NU13 is down-regulated and NOP56 is highly expressed in Wilms tumor. piNU13 may regulate the expression of NOP56 indirectly to inhibit the proliferation, migration and invasion and promote apoptosis of Wilms tumor cells in vitro.

Abstract
OBJECTIVES To evaluate the effect of peri-prostatic adipose tissue (PPAT) measurements using preoperative MRI on the prediction of prostate cancer (PCa) aggressiveness in men undergoing radical prostatectomy (RP). METHODS We performed a retrospective study on 179 consecutive patients receiving RP from June 2016 to October 2018. Clinical characteristics were collected. PPAT measurements including peri-prostatic fat area (PPFA) and peri-prostatic fat area to prostate area (PA) ratio (PPFA/PA) were calculated by MRI. Multivariable logistic regression analysis was performed to identify independent predictors of PCa lymph node metastasis (LNM). The predictive performance was estimated through ROC curves. Nomograms were created based on the predictors. RESULTS Pathologic Gleason score positively correlated with digital rectal examination (DRE), PSA, PPFA/PA, P504S, and Ki-67 (all P < 0.05). ROC curves revealed that high PPFA and high PPFA/PA were associated with LNM (both P < 0.05). Multivariate analysis revealed that high PPFA/PA, pathologic Gleason score, pT stage, and Ki-67 were independently predictive of LNM. The nomograms were created and the C-index was 0.945. CONCLUSIONS PPFA/PA is an independent predictor for LNM along with Gleason score, pT stage, and Ki-67. PPFA/PA may help predict LNM in men undergoing RP, thus providing adjunctive information for therapeutic strategy and prognosis.
