Abstract
Objective: To analyze the prevalence and the risk factors of fungal sepsis in 25 neonatal intensive care units (NICU) among preterm infants in China, and to provide a basis for preventive strategies of fungal sepsis. Methods: This was a second-analysis of the data from the "reduction of infection in neonatal intensive care units using the evidence-based practice for improving quality" study. The current status of fungal sepsis of the 24 731 preterm infants with the gestational age of <34+0 weeks, who were admitted to 25 participating NICU within 7 days of birth between May 2015 and April 2018 were retrospectively analyzed. These preterm infants were divided into the fungal sepsis group and the without fungal sepsis group according to whether they developed fungal sepsis to analyze the incidences and the microbiology of fungal sepsis. Chi-square test was used to compare the incidences of fungal sepsis in preterm infants with different gestational ages and birth weights and in different NICU. Multivariate Logistic regression analysis was used to study the outcomes of preterm infants with fungal sepsis, which were further compared with those of preterm infants without fungal sepsis. The 144 preterm infants in the fungal sepsis group were matched with 288 preterm infants in the non-fungal sepsis group by propensity score-matched method. Univariate and multivariate Logistic regression analysis were used to analyze the risk factors of fungal sepsis. Results: In all, 166 (0.7%) of the 24 731 preterm infants developed fungal sepsis, with the gestational age of (29.7±2.0) weeks and the birth weight of (1 300±293) g. The incidence of fungal sepsis increased with decreasing gestational age and birth weight (both P<0.001). The preterm infants with gestational age of <32 weeks accounted for 87.3% (145/166). The incidence of fungal sepsis was 1.0% (117/11 438) in very preterm infants and 2.0% (28/1 401) in extremely preterm infants, and was 1.3% (103/8 060) in very low birth weight infants and 1.7% (21/1 211) in extremely low birth weight infants, respectively. There was no fungal sepsis in 3 NICU, and the incidences in the other 22 NICU ranged from 0.7% (10/1 397) to 2.9% (21/724), with significant statistical difference (P<0.001). The pathogens were mainly Candida (150/166, 90.4%), including 59 cases of Candida albicans and 91 cases of non-Candida albicans, of which Candida parapsilosis was the most common (41 cases). Fungal sepsis was independently associated with increased risk of moderate to severe bronchopulmonary dysplasia (BPD) (adjusted OR 1.52, 95%CI 1.04-2.22, P=0.030) and severe retinopathy of prematurity (ROP) (adjusted OR 2.55, 95%CI 1.12-5.80, P=0.025). Previous broad spectrum antibiotics exposure (adjusted OR=2.50, 95%CI 1.50-4.17, P<0.001), prolonged use of central line (adjusted OR=1.05, 95%CI 1.03-1.08, P<0.001) and previous total parenteral nutrition (TPN) duration (adjusted OR=1.04, 95%CI 1.02-1.06, P<0.001) were all independently associated with increasing risk of fungal sepsis. Conclusions: Candida albicans and Candida parapsilosis are the main pathogens of fungal sepsis among preterm infants in Chinese NICU. Preterm infants with fungal sepsis are at increased risk of moderate to severe BPD and severe ROP. Previous broad spectrum antibiotics exposure, prolonged use of central line and prolonged duration of TPN will increase the risk of fungal sepsis. Ongoing initiatives are needed to reduce fungal sepsis based on these risk factors.

Abstract
Objective: To observe the effect of progressive core muscle group training combined with lower limb intelligent rehabilitation training on burn patients with lower limb dysfunction. Methods: A prospective randomized controlled study was conducted. From March 2017 to May 2020, 60 patients with motor and balance dysfunction after deep partial-thickness burns or full-thickness burns of both lower extremities who met the inclusion criteria were admitted to the First Affiliated Hospital of Air Force Military Medical University. They were divided into simple intelligent rehabilitation group (30 cases, 20 males and 10 females, aged (40±3) years) and combined rehabilitation group (30 cases, 16 males and 14 females, aged (39±3) years) according to the random number table method. The patients in both groups started red light treatment after the wound healing or when the scattered residual wound area was less than 5% total body surface area. After 2 weeks of red light treatment, patients in the combined rehabilitation group started progressive core muscle group training on the basis of lower limb intelligent rehabilitation training in simple intelligent rehabilitation group, and the training time was 6 weeks. Before and after 6 weeks of training, the lower limb motor function was evaluated with the simple Fugl-Meyer scale, the balance capacity was evaluated with the Berg balance scale, and the walking capacity was evaluated with the Holden walking ability rating scale. After 6 weeks of training, a self-designed questionnaire was used to investigate patients' satisfaction for the treatment effect. The patients were followed up for 6 months after the treatment to observe the balance stability of standing on one foot in the flexion position and their participation in activities of daily life. Data were statistically analyzed with independent sample t test, paired sample t test, and chi-square test. Results: Before training, the lower limb motor function score of patients in simple intelligent rehabilitation group was 24.9±2.7, which was close to 23.9±2.3 in combined rehabilitation group (P>0.05). After 6 weeks of training, the lower limb motor function score of patients in combined rehabilitation group was 29.6±3.9, which was significantly higher than 27.3±3.8 in simple rehabilitation group (t=-2.28, P<0.05). The lower limb motor function scores of patients in combined rehabilitation group and simple intelligent rehabilitation group after 6 weeks of training were significantly higher than those before training (with t values of -6.50 and -3.21, respectively, P<0.01). After 6 weeks of training, the balance capacity score of patients in combined rehabilitation group was 41±7, which was significantly higher than 36±5 in simple intelligent rehabilitation group (t=-2.68, P<0.05); the balance capacity scores of patients in combined rehabilitation group and simple intelligent rehabilitation group after 6 weeks of training were significantly higher than those before training (with t values of -8.72 and -8.09, respectively, P<0.01). After 6 weeks of training, the walking capacity grading of patients in combined rehabilitation group was significantly improved compared with that in simple intelligent rehabilitation group (χ2=-2.14, P<0.05), and the walking capacity grading of patients in simple intelligent rehabilitation group and combined rehabilitation group after 6 weeks of training was significantly improved compared with that before treatment (with χ2 values of -4.94 and -5.26, respectively, P<0.01). After 6 weeks of training, the satisfaction score for the treatment effect of patients in combined rehabilitation group was 13.7±1.2, which was significantly higher than 7.8±1.4 in simple intelligent rehabilitation group (t=22.84, P<0.01). The patients in both groups could stand on one foot to maintain balance in the flexion position of lower limb, and their activities of daily life were not affected 6 months after treatment. Conclusions: On the basis of conventional rehabilitation therapy, the combination of progressive core muscle group training and lower limb intelligent rehabilitation training can significantly promote the recovery of lower limb motor and balance function of burn patients.

Abstract
Objectives To compare the short-term outcomes of unilateral biportal endoscopic lumbar interbody fusion (BLIF) and uniportal endoscopic lumbar interbody fusion (ULIF). Methods Sixty patients diagnosed with L4/5 spinal stenosis who underwent BLIF and ULIF were included (30 in each group). Clinical evaluation was performed preoperatively and postoperatively in the 1st week, 1st month, and 1st year. Factors such as the visual analogue score (VAS), Oswestry Disability Index (ODI), operative time, surgical complications, and radiological outcomes (fusion rate, screw loosening, and cage subsidence) were compared between the two groups. Results All patients showed improved mean VAS and ODI at all three postoperative follow-ups, and no statistically significant differences were detected between the BLIF and ULIF groups. The mean operative time in the BLIF group was shorter than that in the ULIF group. Nerve root injury occurred in two patients in the BLIF group, while leakage of cerebrospinal fluid occurred in one patient in the ULIF group. All adverse events were treated adequately prior to discharge. The fusion rates with definite and probable grades were significantly higher in the BLIF group than that in the ULIF group. One case of cage subsidence with no screw loosening occurred in each group. Conclusion Both BLIF and ULIF are safe and effective surgical techniques. Compared with ULIF, BLIF has the advantages of shorter operative time and a higher fusion rate. Other merits of BLIF include a wider surgical field, greater maneuverability of instruments, visibility during cage implantation, and transverse orientation of the cage.

Abstract
Using a sample of (10.09±0.04)×10^{9} J/ψ events collected with the BESIII detector operating at the BEPCII storage ring, a partial wave analysis of the decay J/ψ→γηη^{'} is performed. The first observation of an isoscalar state with exotic quantum numbers J^{PC}=1^{-+}, denoted as η_{1}(1855), is reported in the process J/ψ→γη_{1}(1855) with η_{1}(1855)→ηη^{'}. Its mass and width are measured to be (1855±9_{-1}^{+6}) MeV/c^{2} and (188±18_{-8}^{+3}) MeV, respectively, where the first uncertainties are statistical and the second are systematic, and its statistical significance is estimated to be larger than 19σ.

Abstract
Abstract
Background
Pulmonary arterial hypertension (PAH) is a progressive disorder characterized by elevated pulmonary artery pressure, right ventricular failure, and premature death. Previous studies showed autonomic nervous system (ANS) such as sympathetic nerve overactivity or impaired parasympathetic activity was implicated in the pathogenesis of PAH. However, PA remodeling and molecular mechanisms involved in ANS in PAH remain unclear.
Purpose
To unravel transcriptional regulation, underlying genes and signaling pathways linking to ANS in PAH.
Methods
Publicly available two RNA sequencing (RNAseq) datasets and one single-cell RNA sequencing (scRNAseq) data of lung from rats with PAH induced by high-dose monocrotaline (MCT) were downloaded and reprocessed. For RNA-seq data, STAR and RSEM were used for read alignment and gene expression qualification. Differential expression genes (DEGs) were identified using DSEseq2, after which enrichment analyses were implemented by clusterProfiler. scRNAseq data were analyzed using Seurat.
Results
Two RNAseq datasets identified a total of 6,046 and 2,172 DEGs respectively, including 2,945 and 1,228 up-regulated and 3,101 and 944 down-regulated. Overlapped DEGs genes among datasets were 1,123 genes. Functional enrichment analysis of downregulated DEGs in one data pointed out many dysregulated pathways related to nerve system, such as nervous system process, neuron projection, integral component of synaptic membrane in MCT-induced PAH rat (Fig. 1a). Both RNAseq datasets supported upregulated DEGs were also involved in pathways related to ANS including humoral immune response and synapse pruning (P<0.001) (Fig. 1a). Intriguingly, all four genes (Trem2, C1qa, C1qb and C1qc) in synapse pruning were progressively upregulated with severe PAH condition (P<0.05) (Fig. 1b, c). And RT-PCR results confirmed the expression level of these four genes were remarkably increased in PAH rats (P<0.0001) (Fig. 1d). These four genes are known marker genes for macrophages from lung and microglial cell from brain. scRNAseq data of lungs demonstrated these four genes were significantly upregulated in alveolar macrophages from MCT-PAH rats (P<0.001) (Fig. 1e). However, the pathogenic mechanisms of these four genes in nerve fibers from lungs underlying PAH have never been studied and would be further explored using histological analysis in this study.
Conclusions
Integrated bioinformatic analysis indicated the association of lung nervous system with PAH. Further, we identified four genes implicated in nervous system, previously reported to link to immune system and provide novel insights into the mechanisms underlying relationship between lung ANS and inflammation in the pathogenesis of PAH. The pathogenetic mechanism of these four genes is being further investigated.

Abstract
Objective: To investigate the effect of arsenic and its main metabolites on the apoptosis of human lung adenocarcinoma cell line A549 and the expression of pro-apoptotic genes Bad and Bik. Methods: In October 2020, A549 cells were recovered and cultured, and the cell viability was detected by the cell counting reagent CCK-8 to determine the concentration and time of sodium arsenite exposure to A549. The study was divided into NaAsO(2) exposure groups and metobol: le expoure groups: the metabolite comparison groups were subdivided into the control group, the monomethylarsinic acid exposure group (60 μmol/L) , and the dimethylarsinic acid exposure group (60 μmol/L) ; sodium arsenite dose groups were subdivided into 4 groups: control group (0) , 20, 40, 60 μmol/L sodium arsenite NaAsO(2). Hoechst 33342/propidium iodide double staining (Ho/PI) was used to observe cell apoptosis and real-time quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of Bad and Bik mRNA in cells after exposure. Western blotting was used to detect the protein expressions of Bad, P-Bad-S112, Bik, cleaved Bik and downstream proteins poly ADP-ribose polymerase PARP1 and cytochrome C (Cyt-C) , using spectrophotometry to detect the activity changes of caspase 3, 6, 8, 9. Results: Compared with the control group, the proportion of apoptotic cells in the 20, 40, and 60 μmol/L NaAsO(2) dose groups increased significantly (P<0.01) , and the expression levels of Bad, Bik mRNA, the protein expression levels of Bad, P-Bad-S112, Bik, cleaved Bik, PARP1, Cyt-C were increased (all P<0.05) , and the activities of Caspase 3, 6, 8, and 9 were significantly increased with significantly differences (P<0.05) . Compared with the control group, the expression level of Bad mRNA in the DMA exposure group (1.439±0.173) was increased with a significant difference (P=0.024) , but there was no significant difference in the expression level of Bik mRNA (P=0.788) . There was no significant differences in the expression levels of Bad and Bik mRNA in the poison groups (P=0.085, 0.063) . Compared with the control group, the gray values of proteins Bad, Bik, PARP1 and Cyt-C exposed to MMA were 0.696±0.023, 0.707±0.014, 0.907±0.031, 1.032±0.016, and there was no significant difference between the two groups (P=0.469, 0.669, 0.859, 0.771) ; the gray values of proteins Bad, Bik, PARP1 and Cyt-C exposed to DMA were 0.698±0.030, 0.705±0.022, 0.908±0.015, 1.029±0.010, and there was no difference between the two groups (P=0.479, 0.636, 0.803, 0.984) . Conclusion: Sodium arsenite induces the overexpression of Bad and Bik proteins, initiates the negative feedback regulation of phosphorylated Bad and the degradation of Bik, activates the downstream proteins PARP1, Cyt-C and Caspase pathways, and mediates the apoptosis of A549 cells.

Abstract
AIM To explore the value of whole-lesion apparent diffusion coefficient (ADC) histogram analysis in discriminating microcystic meningioma (MCM) from atypical meningioma (AM). MATERIALS AND METHODS Clinical and preoperative MRI data of 20 patients with MCM and 26 patients with AM were analysed retrospectively. Whole-lesion apparent diffusion coefficient (ADC) histogram analysis was performed on each patient's lesion to obtain histogram parameters, including mean, variance, skewness, kurtosis, the 1st (ADCp1), 10th (ADCp10), 50th (ADCp50), 90th (ADCp90), and 99th (ADCp99) percentiles of ADC. The differences between the ADC histogram parameters of the two tumours were compared, and the receiver operating characteristic (ROC) curve was used to assess the diagnostic performance of statistically significant parameters in distinguishing the two tumours. RESULTS The mean, ADCp1, ADCp10, ADCp50, and ADCp90 of MCM were greater than those of AM, and significant differences were observed in these parameters between MCM and AM (all p<0.05). ROC analysis showed that the mean had the highest area under the curve value (AUC) in distinguishing the two tumours (AUC = 0.852), when using 120.46 × 10-6 mm2/s as the optimal threshold, the sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for discriminating the two groups were 84.6%, 75%, 80.4%, 81.5%, and 78.9%, respectively. CONCLUSION Histogram analysis based on whole-lesion ADC maps was useful for discriminating between MCM from AM preoperatively, with the mean being the most promising potential parameter.

Abstract
Based on (10087±44)×10^{6} J/ψ events collected with the BESIII detector, the process J/ψ→γπ^{+}π^{-}η^{'} is studied using two largest decay channels of the η^{'} meson, η^{'}→γπ^{+}π^{-} and η^{'}→ηπ^{+}π^{-}, η→γγ. A new resonance, which we denote as the X(2600), is observed with a statistical significance larger than 20σ in the π^{+}π^{-}η^{'} invariant mass spectrum, and it has a connection to a structure around 1.5 GeV/c^{2} in the π^{+}π^{-} invariant mass spectrum. A simultaneous fit on the π^{+}π^{-}η^{'} and π^{+}π^{-} invariant mass spectra with the two η^{'} decay modes indicates that the mass and width of the X(2600) state are 2618.3±2.0_{-1.4}^{+16.3} MeV/c^{2} and 195±5_{-17}^{+26} MeV, where the first uncertainties are statistical, and the second systematic.

Abstract
The development of chemo/photothermal nanotherapeutic systems with excellent photothermal performance, stable drug loading, tumor targeting and strong membrane penetration still remains a challenge. To address this problem, herein a rod-like nanocomposite system (AuNR@FA-PR/PEG) forming from folic acid (FA) terminated carboxylated cyclodextrin (CD) pseudopolyrotaxane (FA-PR) and polyethylene glycol (PEG) modifying gold nanorods (AuNR) was reported. Cisplatin (CDDP) was loaded in AuNR@FA-PR/PEG via coordination bonds to prepare a rod-like pH-responsive nanosystem (AuNR@FA-PR/PEG/CDDP) with chemotherapy/photothermal therapy. The rod-like morphology of AuNR@FA-PR/PEG was characterized by transmission electron microscope. In vitro drug release experiments showed the pH-responsive of AuNR@FA-PR/PEG/CDDP. In vivo real-time imaging assays proved AuNR@FA-PR/PEG/CDDP could rapidly enrich in the tumor area and stay for a long time because of folate targeting and their rod-like morphology. In vivo photothermal imaging assays showed AuNR@FA-PR/PEG/CDDP excellent photothermal performance, the average temperature of tumor region could reach 63.5 °C after 10 min irradiation. In vitro and in vivo experiments also demonstrated that the combined therapy of chemotherapy and photothermal therapy had an outstandingly synergistic effect and improved the therapeutic efficacy comparing with chemotherapy and photothermal therapy alone. Therefore, the prepared rod-like AuNR@FA-PR/PEG/CDDP will provide a new strategy for the effective treatment of cancer.

Abstract
Objective: To investigate the clinical and pathological features and prognosis of patients with microfocal prostate adenocarcinoma. Methods: Clinical and pathological data of the patients diagnosed with microfocal adenocarcinoma on prostate biopsy at the West China Hospital from 2013 to 2019 were collected. Microfocal adenocarcinoma was defined as follows: Gleason score of 3+3=6, total number of the cores ≥10, number of the positive cores ≤2, and proportion of the tumor in each positive core<50%. Clinicopathological parameters, treatment plans and follow-up data were collected. Pathological information of the biopsy and radical resection specimens was used to analyze the correlation between pathological parameters in the biopsy report and adverse pathological features of radical resection specimens, including increased Gleason score, capsule invasion, positive surgical margin and perineural invasion. Results: A total of 206 cases of microfocal adenocarcinoma were diagnosed on prostate biopsies from 2013 to 2019, accounting for 6.7% of all adenocarcinoma cases. There were 139 cases of 1 positive core and 67 cases of 2 positive cores. Patients with microfocal adenocarcinoma were younger than those with non-microfocal adenocarcinoma (69 years versus 71 years, P<0.001). Compared with patients with non-microfocal adenocarcinoma, the pre-biopsy total prostate specific antigen (tPSA) and free prostate specific antigen (fPSA) levels in patients with microfocal adenocarcinoma were both lower (11.2 μg/L2 versus 23.7 μg/L2; 1.4 μg/L2 versus 3.0 μg/L2, P<0.001), the fPSA/tPSA level was higher (12.9% versus 10.7%, P<0.05), the prostate volume was larger (38.9 mL versus 34.3 mL, P<0.05), and the PSA density was lower (0.3 μg/L2 versus 0.8 μg/L2, P<0.001). 130 patients underwent radical prostatectomy, 30 patients chose active monitoring, 31 patients chose endocrine or radiation therapy, and 15 patients were lost to follow-up. Three patients in the active surveillance group underwent radical prostatectomy for disease progression after 21-39 months observation. Biochemical relapses occurred in two patients in the radical prostatectomy group. The remaining patients have no disease progression or recurrence at present. Compared with radical prostatectomy specimens, Gleason score in the biopsy material was increased in 64/115 patients (55.7%). Among resection excision specimens, 14 cases (12.2%) had extraprostatic extension (EPE), 35 cases (30.4%) had perineural invasion, and 16 cases (13.9%) had a positive margin. Univariate and multivariate analyses showed that low fPSA/tPSA ratio and 2 positive cores were independent risk factors for Gleason score increase in the radical prostatectomy specimens. A low fPSA/tPSA ratio was an independent risk factor for perineural invasion. Low fPSA/tPSA ratio and low prostate volume were associated with a positive margin in radical prostatectomy specimens. Conclusions: In this study, patients diagnosed with microfocal adenocarcinoma on prostate biopsy account for a high proportion of the patients with increased Gleason score in the radical prostatectomy specimens, and there is a certain proportion of adverse pathological features in the radical specimens. Therefore, for the patients with only a small amount of low-grade adenocarcinoma found in biopsy, PSA levels and PSA density should be taken into consideration in treatment selection.

Using a sample of about 10^{10} J/ψ events collected at a center-of-mass energy sqrt[s]=3.097 GeV with the BESIII detector, the electromagnetic Dalitz decays J/ψ→e^{+}e^{-}π^{+}π^{-}η^{'}, with η^{'}→γπ^{+}π^{-} and η^{'}→π^{+}π^{-}η, have been studied. The decay J/ψ→e^{+}e^{-}X(1835) is observed with a significance of 15σ, and also an e^{+}e^{-} invariant-mass dependent transition form factor of J/ψ→e^{+}e^{-}X(1835) is presented for the first time. The intermediate states X(2120) and X(2370) are also observed in the π^{+}π^{-}η^{'} invariant-mass spectrum with significances of 5.3σ and 7.3σ. The corresponding product branching fractions for J/ψ→e^{+}e^{-}X, X→π^{+}π^{-}η^{'} [X=X(1835), X(2120), and X(2370)] are reported.

Abstract
Abstract
Study question
Could cell-free RNA (cfRNA) in culture medium be non-invasive strategy to select in vitro fertilized (IVF) embryos?
Summary answer
CfRNAs in culture medium could be potential markers correlated with embryo qualities.
What is known already
Infertility is a critical component of reproductive health and couples with infertility may choose assisted reproductive technology (ART) to increase their chances of conception. However, the effectiveness remains low. One way to improve the outcome is to screen the embryo prior to implantation. Noninvasive testing opens new perspectives in analyzing embryo qualities and current pending includes microscopy images coupled with artificial intelligence and omics analysis of the spent blastocyst medium (SBM). Cell-free DNA in SBM could be used to identify the embryo ploidy and metabolomic/proteomic markers could be correlated with embryo potential, while the research of cfRNA is lacking.
Study design, size, duration
We developed a new library method of polyadenylation ligation-mediated sequencing (PALM-Seq) to capture the low amount of cfRNA and collected twelve culture mediums of in vitro embryos on Day 3 and five samples of embryos on Day 5.
Participants/materials, setting, methods
We employed PALM-Seq on culture medium of embryos generated by IVF or Intracytoplasmic sperm injection (ICSI). Owing to the new method, we could comprehensively profile the cfRNAs, including miRNA, tRNA, piRNA, lncRNA and mRNA. The morphology and fragmentation of the recruited embryos were also recorded.
Main results and the role of chance
Generally, thousands of genes could be detected in all culture mediums and the number greatly increased in SBM. We identified several reported miRNA markers in our study, such as miR-21-5p and miR-92a-3p, while highly expressed miRNAs varied across samples and stages. We indeed found piRNA in mediums and several specific piRNAs had large amount of expression. In contrast, detected number and expression of tRNA were stable across samples. Besides of reported mRNA markers, we could profile the expression of all detected mRNAs and no differences were found between embryos with and without fragmentation. We found that the majority of mRNA fragments were shorter than 30 nucleotides. In addition, some granular-specific expressed mRNAs could be detected in medium on Day 3 and they decreased of medium on Day 5.
Limitations, reasons for caution
We have only conducted preliminary exploration in the culture medium of pre-implantation embryos and studies of larger sample size are needed.
Wider implications of the findings
Our research proved the feasibility of performing high-throughput sequencing of cfRNAs in SBM. It opens new perspectives on defining non-invasive markers and selection of embryos with the most potential. Our results also contribute a new insight on improving the treatment of infertility.
