Abstract
OBJECTIVE Patients with advanced tumors often suffer from spinal metastatic tumor pain. The current drugs are less effective and have side effects. The objective was to explore the efficacy of iodine-125 particle implantation in the treatment of bone metastatic tumor pain. PATIENTS AND METHODS In a retrospective study, a total of 27 patients with bone metastatic tumors who could not receive surgery or radiotherapy and chemotherapy were analyzed. All patients received conventional treatment, with the visual analog scale (VAS) of >3 points, and the daily onset pain of >3 times. All patients received CT-guided iodine-125 particle implantation to treat local painful lesions. VAS scores were recorded before treatment (T0) and 1 day (T1), 7 days (T2), 30 days (T3), 90 days (T4), and 180 days (T5) after treatment. Kaplan-Meier analytical method was used to calculate the local control rate (LCR) and survival rate (SR). RESULTS All patients successfully completed the CT-guided iodine-125 particle implantation. There was no significant difference in VAS scores before and 1 day after surgery. However, compared with pre-operation, the VAS scores decreased at 7, 30, 90, and 180 days after surgery. The postoperative follow-up was 6-38 months, with a median of 16 months; the LCR at 1, 2, and 3 years after the follow-up were 87%, 51%, and 21%, respectively, and the SR was 84%, 43%, and 16%, respectively. Moreover, no serious adverse reactions were observed. CONCLUSIONS Iodine-125 particle implantation was effective in the treatment of bone metastatic tumor pain without serious complications, and hence, can be used clinically.

Abstract
BACKGROUND Perinatal practices such as breast-feeding, kangaroo mother care, rooming-in, and delayed cord clamping have varied by institution during the COVID-19 pandemic. The goal of this systematic review was to examine the success of different practices in preventing viral transmission between SARS-CoV-2 positive mothers and their infants. METHODS Electronic searches were performed in the Ovid MEDLINE, Ovid Embase, Cochrane Library, EBSCOhost CINAHL Plus, Web of Science, and Scopus databases. Studies involving pregnant or breastfeeding patients who tested positive for SARS-CoV-2 by RT-PCR were included. Infants tested within 48 hours of birth who had two tests before hospital discharge were included. Infants older than one week with a single test were also included. RESULTS Twenty eight studies were included. In the aggregated data, among 190 breastfeeding infants, 22 tested positive for SARS-CoV-2 (11.5%), while 4 of 152 (2.63%) among bottle-fed (Fisher's exact test p = 0.0006). The positivity rates for roomed in infants (20/103, 19.4%) were significantly higher than those isolated (5/300, 1.67%) (P < 0.0001). There was no significant difference in positivity rate among infants who received kangaroo care (25%vs 9%, p = 0.2170), or delayed cord clamping (3.62%vs 0.9%, p = 0.1116). CONCLUSIONS Lack of robust studies involving large patient population does not allow meaningful conclusions from this systematic review. Aggregated data showed increased positivity rates of SARS-CoV-2 among infants who were breast fed and roomed-in. There were no differences in SARS-CoV-2 positivity rates in infants received skin to skin care or delayed cord clamping.

Abstract
nirK-type and nirS-type denitrifier communities mediate the conversion of nitrite to nitric oxide, which is the key step in denitrification. Results of previous studies have indicated that nirK-type and nirS-type denitrifiers may occupy different niches; however, the mechanisms and drivers of their responses to environmental changes within community assembly are poorly understood. In this study, we evaluated the distribution and assembly of nirK-type and nirS-type denitrifier communities along an elevation gradient from 1,800 to 4,100 m at Mount Gongga, China. Results showed that elevational patterns of alpha diversity in nirK-type and nirS-type denitrifier communities followed hump-backed patterns along the elevation gradient. However, nirK-type denitrifier communities formed two distinct clusters that were primarily separated by elevation, whereas nirS-type denitrifier communities formed three distinct clusters that were primarily separated by forest type along the elevation gradient. Moreover, deterministic processes were dominant in governing the assemblages of nirK-type and nirS-type denitrifiers. Soil pH was a key factor influencing the alpha and beta diversity of the nirK-type denitrifier communities, whereas plant richness was a primary variable influencing nirS-type denitrifiers. Additionally, our work revealed that soil denitrification potential was mainly explained by the variation in the beta diversity of denitrifier communities rather than the alpha diversity of denitrifier communities or denitrifier abundances over a large elevation gradient, and nirK-type denitrifiers played more important roles in soil denitrification. These results may contribute to predicting the consequences of global changes on denitrifier communities and their ecological services. IMPORTANCE Mount Gongga is the highest peak in the Hengduan Mountain region and is located at the southeastern fringe of the Tibetan Plateau, Sichuan Province, southwest China. As a transitional zone between the Tibetan Plateau and Sichuan Basin, Gongga Mountain features particularly diverse topography, geology, climate, and biodiversity and is a globally significant hot spot of biodiversity. In this contribution, we comprehensively describe the diversity and assembly of denitrifier communities along an elevation gradient on Gongga Mountain. Our findings established for the first time that the distribution patterns of beta diversity and driving factors differed between nirK-type and nirS-type denitrifier communities, and deterministic processes were dominant in shaping communities of denitrifiers. Moreover, the beta diversity of denitrifier communities rather than alpha diversity or denitrifier abundance played an important role in explaining denitrification potential, and the beta diversity of nirK-type denitrifier communities was more important than nirS-type denitrifier communities in soil denitrification. This work provides crucial insights into the spatial distribution of denitrifier communities and their ecological function and increases our understanding of the mechanisms underlying spatial distribution of community assembly along large elevation gradients.

Abstract
All-organic proton batteries are attracting extensive attention due to their sustainability merits and excellent rate capability. Generally, strong acids (e.g. H2 SO4 ) have to be employed as the electrolytes to provide H+ for all-organic proton batteries due to the high H+ intercalation energy barrier. Until now, the design of all-organic proton batteries in mild electrolytes is still a challenge. Herein, a poly(2,9-dihydroquinoxalino[2,3-b]phenazine) (PO) molecule was designed and synthesized, where the adjacent C=N groups show two different chemical environments, resulting in two-step redox reactions. Moreover, the two reactions possess considerable voltage difference because of the large LUMO energy gap between PO and its reduction product. More impressively, the C=N groups endow the π-conjugated PO molecule with H+ uptake/removal in the ZnSO4 electrolyte. As a result, a symmetric all-organic proton battery is achieved in a mild electrolyte for the first time, which exhibits enhanced electrochemical performance and also broadens the chemistry of proton-based batteries.

Abstract
Objective: To analyze the expression of CD44 in non-alcoholic fatty liver disease (NAFLD) accompanied with hepatitis B virus (HBV) infection and its clinical significance. Methods: Blood sample of hospitalized patients with NAFLD, chronic hepatitis B, cirrhosis, and healthy population (control) was collected. The study was approved by the hospital ethics committee. Serum CD44 level and clinopathological characteristics were analyzed quantitatively by enzyme-linked immunosorbent-assay. Flow cytometry was used to analyze the proportion of CD44(+)T lymphocytes in patients with NAFLD and chronic hepatitis B. NAFLD model was prepared with high-fat diet to verify the abnormal expression of CD44. Results: Compared with the healthy control group, the expression of serum CD44 in the cirrhosis group, chronic hepatitis B group and NAFLD group was increased, and the difference between the groups were statistically significant (P < 0.01). NAFLD patients graded as mild or severe group were equally accompanied by hepatocyte injury, abnormal blood glucose, lipid or CD44. In NAFLD patients accompanied with HBV infection, serum CD44 concentrations were significantly higher in HBsAg, HBeAg and HBV DNA positive group than HBsAg, HBeAg and HBV DNA negative group (P < 0.01). The proportion of CD44(+)T lymphocytes in peripheral blood of NAFLD and chronic hepatitis B group were 78.2% ± 16.3% and 68.5% ± 20.9%, respectively, and both groups (NAFLD and chronic hepatitis B) were significantly higher than the healthy control group (46.5% ± 20.5%) (P < 0.05). The high-fat diet model confirmed that in rat liver tissues the CD44 was overexpressed with fat deposition accompanied with liver cell damage, especially remarkable in liver tissues containing carcinogens. Conclusion: The abnormal expression of CD44 in patients with NAFLD may be related to the malignant transformation of HBV-related liver disease.

Abstract
Objective: To explore the value of Krüppel-like factor 5 (KLF5), a family member of the zinc finger protein transcription factor, in the diagnosis and prognostic evaluation of hepatocellular carcinoma (HCC). Methods: Cancerous and non-cancerous tissues were collected from 126 cases after HCC surgery by self-matching method with microarray fabrication. Immunohistochemistry was used to analyze the expression of KLF5, clinicopathological characteristics and prognostic value. The sera of 222 cases with chronic liver disease were collected and their KLF5 levels were quantitatively determined by enzyme-linked immunosorbent assay (ELISA). Simultaneously, 40 normal human sera were used as controls to evaluate the value of abnormal KLF5 in the diagnosis and differentiation of benign and malignant liver diseases. T-test, Z-test and χ (2) test were performed on the data. Results: The positive expression rate of KLF5 in the HCC group was 95.2% (120/126), which was significantly higher than the non-cancerous group 38.9% (49/126; χ (2) = 14.385, P < 0.001). KLF5 expression was significantly correlated with TNM stage (stage I 35%, stage II 40%, stage III 74.4%, stage IV 78.1%), tumor size, alpha fetoprotein (AFP) concentration, portal vein embolism, HBV infection and 5-year survival rate. Univariate/multivariate analysis showed that KLF5 high expression was an independent predictor of HCC prognosis. The serum KLF5 level was significantly higher in HCC patients than liver cirrhosis, chronic hepatitis and normal control group (P < 0.001). With the serum KLF5 > 800 ng/ml and AFP > 25 μg/L as limit, the positive rates for HCC diagnosis were 90.48% and 73.81%, respectively, which were lower than the AFP specificity and false positive rate, and was helpful for the differential diagnosis of benign and malignant liver diseases. Conclusion: The overexpression of KLF5 in liver cancer tissues and blood is closely related to the HCC clinical stage and prognosis. Moreover, KLF5 analysis is helpful for HCC diagnosis and differential diagnosis.

Abstract
Abstract
Study question
Does mitochondrial DNA content (mtDNA) correlate with clinical parameters and embryo morphokinetics using advanced time-lapse technology?
Summary answer
mtDNA correlated with embryo morphokinetics and the growth trajectory of euploid embryos. Maternal age, anti-mullerian hormone level and fertility diagnosis were significantly associated with mtDNA.
What is known already
With the push towards single embryo transfers, laboratories are working to improve embryo selection. In addition to conventional microscopy, preimplantation genetic testing and time-lapse microscopy have been utilized to aid in embryo selection. More recently, as mtDNA may represent the energy potential of an embryo, some data have supported the use of mtDNA as an additional tool. Limited studies have suggested that a lower amount of mtDNA is associated with higher rates of implantation and improved embryo quality.
Study design, size, duration
This is a retrospective chart review. All embryos that underwent preimplantation genetic testing for aneuploidy (PGT-A) between January to December of 2020 were studied.
Participants/materials, setting, methods
Women undergoing in vitro fertilization (IVF) with intracytoplasmic sperm injection undergoing PGT-A were studied. All patients were from a single academic institution. This study exclusively examined the characteristics of euploid embryos. Mitochondrial DNA content was expressed as a ratio of mtDNA:nDNA (MitoScore). Time-lapse imaging was utilized to evaluate embryo development every 15 minutes in 5–7 focal planes. Chi square test and Spearman correlation analysis were performed with a p-value of < 0.05 considered significant.
Main results and the role of chance
A total of 494 embryos from 52 women who underwent 58 IVF cycles were cultured to blastocyst and 331 embryos were biopsied for PGT-A evaluation. Of these, 132 embryos were diagnosed as euploid. A moderate positive correlation was found between MitoScore and time to morula, time to blast and time to expanded blast (correlation value 0.54, 0.50 and 0.54, respectively; p < 0.001). Consistent with this trend, day 5 blastocysts had a significantly lower MitoScore values than day 6 blastocysts (20.2 v. 29.2; p < 0.001). When examining all biopsied euploid embryos, no significant association was found between MitoScore, blastocyst maturity, trophectoderm or inner cell mass scores.
Our data also demonstrated a positive correlation between MitoScore and maternal age (correlation factor 0.33; p < 0.001). A negative association between MitoScore and serum anti-mullerian hormone levels (correlation factor –0.20; p < 0.021) was also noted. Of particular interest was the significant association between fertility diagnosis and mitochondrial score (p < 0.001).
Even amongst euploid embryos, mtDNA content varied widely, potentially reflecting differences in embryo potential and quality. Additionally, the significant difference in MitoScore between that day 5 and day 6 blastocysts may reflect a fundamental difference in cytoplasmic characteristics and requires further study.
Limitations, reasons for caution
Due to the study cohort of euploid embryos undergoing PGT-A, this study was biased for the selection of high grade embryos. This limited diversity in embryo quality may have masked other potential associations between mitochondrial content and blastocyst quality.
Wider implications of the findings: mtDNA may be additional tool aiding in embryo selection as IVF labs work to improve pregnancy rates while minimizing the risks of transferring multiple embryos. To our knowledge, this is the largest study assessing the relationship of mtDNA content of blastocysts and the timing of embryo development using time-lapse imaging.

Abstract
Abstract
Study question
Can the gas-liquid interface organ culture system that achieved in vitro spermatogenesis in mice also support in vitro spermatogenesis in human adult testis?
Summary answer
Although the progression of spermatogenesis was not observed, germ cells were maintained without the degeneration of the architecture in both fresh and cryopreserved testicular tissues.
What is known already
Although the research on in vitro spermatogenesis have been conducted for 100 years, only the organ culture system using gas-liquid interface method achieved in vitro spermatogenesis in mice. It has not been verified whether this culture system can be applied to other mammals including humans and induce spermatogenesis.
Study design, size, duration
Testicular tissue was obtained from the transgender patients receiving sex reassignment surgery. Testicular specimens were either immediately processed for cultivation or cryopreserved, using a vitrification freezing protocol. Organ culture of testicular fragments was performed in three different media for a maximum period of 3 weeks to evaluate the short-term changes in the cultured tissues (viability, proliferation and maintenance of germ and somatic cells).
Participants/materials, setting, methods
Fresh and cryopreserved-thawed testis fragments (1–2 mm3) were cultured using the organ culture system in alpha-MEM with knock-out serum replacement (K group), alpha-MEM with lipid-rich BSA (A group) and DMEM with FBS (D group). Luteinizing hormone, follicle stimulating hormone and testosterone were supplemented. The number of germ cells (using DDX4), proliferative activity of germ cells (using EdU assay) and intratubular cell apoptosis (by TdT-mediated dUTP Nick End Labeling) were evaluated by immunohistochemical staining weekly.
Main results and the role of chance
The architecture of the seminiferous tubules was maintained until the second week of culture in both the fresh and the cryopreserved culture group. The number of DDX4-positive germ cells per seminiferous tubule in groups D, K, and A was 49 ± 24, 55 ± 21, 50 ± 26 cells/tubule in 1 day, 32 ± 13, 42 ± 7, 36 ± 21 cells/tubule in 1week, respectively. The numbers gradually decreased to 26 ± 8, 24 ± 6 and 27 ± 18 cells/tubule, in 2 weeks, respectively, with no difference among the groups. The number of intratubular EdU-positive cells of groups D, K, and A was 0.2 ± 0.2, 2.8 ± 2.1, 1.1 ± 0.8 cells/tubule at 1 day, 0.1 ± 0.2, 0.5 ± 0.6, 0.3 ± 0.6 cells/tubule at 1 week, respectively. The values were 0.01, 0.05, and 0.03 at 2 weeks. Thus, EdU-positive cells drastically decreased from the first week of culture. The number of DDX4-positive germ cells and the intratubular EdU-positive cells in the cryopreserved culture group was not different from that in the fresh culture group.
Limitations, reasons for caution
Current organ culture systems are incomplete, being unable to induce human in vitro spermatogenesis. Further research is needed to improve culture condition with the aim of producing fertile sperm of infertile adult male patients.
Wider implications of the findings: Our organ culture system could maintain testis structure and germ cells. By using the testis tissues of the transgender patients, which are available with their consent, we will promote the investigation of the culture condition necessary for germ cell proliferation and differentiation.

Abstract
Objective: To analyze the expression of tuftelin protein (TUFT1) and its clinical value in hepatocellular carcinoma (HCC)-related liver cancer tissues. Methods: The biological information data of TUFT1 mRNA expression in liver cancer and non-cancer tissues were analyzed from the TCGA and Oncomine database. After the approval of the ethics committee, the self-pairing method was used to collect the postoperative cancer and para-carcinoma tissues of 132 HCC cases hospitalized between January 2009 and December 2014. Tissue microarray and immunohistochemistry (IHC) were used to analyze the expression of TUFT1 in liver tissues. According to IHC staining, liver cancer was divided into high TUFT1 and low/no expression group. Combined with clinical data, the clinicopathological characteristics were statistically analyzed between and within the groups. The 5-year overall survival (OS) and disease-free survival (DFS) was analyzed by correlation analysis. Results: IHC staining showed that TUFT1 in cancer tissue was localized in the cytoplasm and cell membrane, and its positive expression rate was significantly higher in the liver cancer group (87.1%) than the para-carcinoma group (64.4%) (χ (2) = 18.563, P < 0.001). TUFT1 expression intensity in patients with liver cancer was significantly correlated with HBeAg positive (χ (2) = 4.080, P = 0.043), tumor size (χ (2) = 9.388, P = 0.002), vascular invasion (χ (2) = 14.885, P < 0.001), TNM stage (χ (2) = 13.516, P < 0.001) and ascites (χ (2) = 5.940, P = 0.015). TUFT1 high expression was negatively correlated with OS and DFS (P < 0.001). Conclusion: The overexpression of TUFT1 is closely related to HBV replication, vascular invasion and poor prognosis, and it is expected to become a useful marker for liver cancer diagnosis and prognosis.

Abstract
OBJECTIVE Transcriptome data related to severe acute respiratory syndrome-related coronavirus 2 (a novel coronavirus discovered in 2019, SARS-CoV-2) in GEO database were downloaded. Based on the data, influence of SARS-CoV-2 on human cells was analyzed and potential therapeutic compounds against the SARS-CoV-2 were screened. MATERIALS AND METHODS R package "DESeq2" was used for differential gene analysis on the data of cells infected or non-infected with SARS-CoV-2. The "ClusterProfiler" package was used for GO functional annotation and KEGG pathway enrichment analysis of the differentially expressed genes (DEGs). A protein-protein interaction (PPI) network of the DEGs was constructed through STRING website, and the key subset in the PPI network was identified after visualization by Cytoscape software. Connectivity Map (CMap) database was used to screen known compounds that caused genomic change reverse to that caused by SARS-CoV-2. RESULTS By intersecting DEGs in two datasets, a total of 145 DEGs were screened out, among which 136 genes were upregulated and 9 genes were downregulated in SARS-CoV-2-infected cells. Functional enrichment analyses revealed that these genes were mainly associated with the pathways involved in viral infection, inflammatory response, and immunity. The CMap research found that there were three compounds with a median_tau_score less than -90, namely triptolide, tivozanib and daunorubicin. CONCLUSIONS SARS-CoV-2 can cause abnormal changes in a large number of molecules and related signaling pathways in human cells, among which IL-17 and TNF signaling pathways may play a key role in pathogenic process of SARS-CoV-2. Here, three compounds that may be effective for the treatment of SARS-CoV-2 were screened, which would provide new options for improving treatment of patients infected with SARS-CoV-2.

Abstract
Objective: To explore the role of macrophages in non-alcoholic steatohepatitis (NASH) in order to provide directions for the therapeutic target of metabolic liver disease. Methods: Twenty C57BL/6 wild-type male mice at 6-8 weeks were randomly divided into two groups: 5 in the control group, methionine-and choline-deficient diet (MCD); 15 in the experimental group, MCD diet + intraperitoneal injection of disodium chlorophosphonate liposomes (to clear macrophages). Mice were fed for 4 weeks to establish NASH model. Blood, liver and spleen were collected to analyze the body mass index, liver index, spleen index, and serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels. Non-alcoholic steatosis (NAS) activity score was evaluated by HE and Oil Red O staining. The relative expression level of F4/80 mRNA was compared by RT-PCR. Data comparison between groups was analyzed by t-test. Results: NASH model was successfully established by feeding the mice with MCD for four week. The expression of F4/80 mRNA (t = 4.167, P < 0.01), hepatic steatosis (t = 10.70, P < 0.05), interlobular inflammatory infiltration (t = 3.08, P < 0.05), and NAS score were decreased (t = 8.06, P < 0.05) in the experimental group. At the same time, ALT level [(817.00 ± 128.90) U/L vs. (231.20 ± 36.28) U/L, t = 5.71, P < 0.01], AST level [(1 211.00 ± 248.90) U/L vs. (505.30 ± 88.20) U/L, t = 3.32, P < 0.01] was decreased significantly. However, the spleen volume and spleen index of the experimental group were larger (0.24 ± 0.01 and 0.32 ± 0.02, t = 2.41, P < 0.05), and there was no significant effect on liver ballooning, body mass index and liver index. Conclusion: In NASH, phosphonate can consume macrophages to inhibit liver inflammation and protect the damaged liver.

Abstract
A large amount of sequencing data is produced in microbial community ecology studies using the high-throughput sequencing technique, especially amplicon-sequencing-based community data. After conducting the initial bioinformatic analysis of amplicon sequencing data, performing the subsequent statistics and data mining based on the operational taxonomic unit and taxonomic assignment tables is still complicated and time-consuming. To address this problem, we present an integrated R package-'microeco' as an analysis pipeline for treating microbial community and environmental data. This package was developed based on the R6 class system and combines a series of commonly used and advanced approaches in microbial community ecology research. The package includes classes for data preprocessing, taxa abundance plotting, venn diagram, alpha diversity analysis, beta diversity analysis, differential abundance test and indicator taxon analysis, environmental data analysis, null model analysis, network analysis and functional analysis. Each class is designed to provide a set of approaches that can be easily accessible to users. Compared with other R packages in the microbial ecology field, the microeco package is fast, flexible and modularized to use and provides powerful and convenient tools for researchers. The microeco package can be installed from CRAN (The Comprehensive R Archive Network) or github (https://github.com/ChiLiubio/microeco).

Abstract
OBJECTIVE Neuropathic pain is directly developed from lesions or somatosensory nervous system diseases that are associated with emotion regulation. In general population, the incidence of neuropathic pain ranges from 7% to 10%, but the underlying mechanism remains largely unknown. Neuropathic pain is often associated with structural and functional abnormalities in multiple brain regions, and its regulation has been shown to correspond with the forebrain, including nucleus accumbens (NAc), medial prefrontal cortex (mPFC) and periaqueductal gray (PAG). MATERIALS AND METHODS To investigate the molecular mechanism of neuropathic pain across different brain regions, we identified the differentially expressed genes (DEGs) between the spared nerve injury model (SNI) mice suffering neuropathic pain and the control Sham mice in NAc, mPFC and PAG three brain regions, and mapped these genes onto a comprehensively functional association network. Thereafter, novel neuropathic pain genes in these three regions were identified using With Random Walk with Restart (RWR) analysis, such as Asic3, Cd200r1 and MT2, besides well-known Capn11 and CYP2E1. RESULTS Interactions or cross talks among DEGs in NAc, mPFC and PAG three brain regions were discovered. CONCLUSIONS Our results provide novel insights into neuropathic pain and help to explore therapeutic targets in the treatment.

Abstract
Non-small cell lung cancer (NSCLC) is characterized with high morbidity and mortality, mainly due to frequent recurrence and metastasis. However, the underlying molecular mechanisms of NSCLC tumorigenesis are largely unclear. Through data mining in the ONCOMINE and Gene Expression Omnibus (GEO) databases, the expression of CSE1L (chromosome segregation like 1 protein/CAS), an exportin, was identified to be significantly upregulated in NSCLC and positively associated with poor prognosis of patients. By use of in vitro and in vivo gain- and loss-of-function experiments, we found that CSE1L can promote NSCLC cell proliferation while inhibiting cell apoptosis. Through immunoprecipitation and mass spectrometry experiments, we demonstrated that CSE1L interacted with RELA (named as P65) and affected its location in the nucleus. Moreover, we found that one of the mechanisms by which CSE1L promotes proliferation and inhibits apoptosis is through activating the nuclear factor-κB (NF-κB)/mitogen-activated protein kinase (MAPK) signaling pathway. In summary, our findings indicated an oncogenic role of CSE1L in NSCLC tumorigenesis.
