- Abstract
Liquid crystal monomers (LCMs) are emerging organic pollutants due to their potential persistence, toxicity, and bioaccumulation. This study first characterized the levels and compositions of 19 LCMs in organisms in the Pearl River Estuary (PRE), estimated their bioaccumulation and trophic transfer potential, and identified priority contaminants. LCMs were generally accumulated in organisms from sediment, and the LCM concentrations in all organisms ranged from 32.35 to 1367 ng/g lipid weight. The main LCMs in organisms were biphenyls and analogues (BAs) (76.6%), followed by cyanobiphenyls and analogues (CBAs) (15.1%), and the least were fluorinated biphenyls and analogues (FBAs) (11.2%). The most abundant LCM monomers of BAs, FBAs, and CBAs in LCMs in organisms were 1-(4-propylcyclohexyl)-4-vinylcyclohexane (15.1%), 1-ethoxy-2,3-difluoro-4-(4-(4-propylcyclohexyl) cyclohexyl) benzene (EDPBB, 10.1%), and 4'-propoxy-4-biphenylcarbonitrile (5.1%), respectively. The niche studies indicated that the PRE food web was composed of terrestrial-based diet and marine food chains. Most LCMs exhibited biodilution in the terrestrial-based diet and marine food chains, except for EDPBB and 4,4'-bis(4-propylcyclohexyl) biphenyl (BPCHB). The hydrophobicity, position of fluorine substitution of LCMs, and biological habits may be important factors affecting the bioaccumulation and trophic transfer of LCMs. BPCHB, 1-(prop-1-enyl)-4-(4-propylcyclohexyl) cyclohexane, and EDPBB were characterized as priority contaminants. This study first reports the trophic transfer processes and mechanisms of LCMs and the biomonitoring in PRE.

- Abstract
The miR390-derived TAS3 trans-acting short-interfering RNAs (tasiRNAs) module represents a conserved RNA silencing pathway in the plant kingdom; however, its characterization in the bryophyte Marchantia polymorpha is limited. This study elucidated that MpDCL4 processes MpTAS3 double-stranded RNA (dsRNA) to generate tasiRNAs, primarily from the 5'- and 3'-ends of dsRNA. Notably, we discovered a novel tasiRNA, tasi78A, which can negatively regulate a cytochrome P450 gene, MpCYP78A101. Additionally, tasi78A was abundant in MpAGO1, and transient expression assays underscored the role of tasi78A in repressing MpCYP78A101. A microRNA, miR11700, also regulates MpCYP78A101 expression. This coordinate regulation suggests a role in modulating auxin signaling at apical notches of gemma, influencing the growth and sexual organ development of M. polymorpha and emphasizing the significance of RNA silencing in MpCYP78A101 regulation. However, phylogenetic analysis identified another paralog of the CYP78 family, Mp1g14150, which may have a redundant role with MpCYP78A101, explaining the absence of noticeable morphological changes in loss-of-function plants. Taken together, our findings provide new insights into the combined regulatory roles of miR390/MpTAS3/miR11700 in controlling MpCYP78A101 and expand our knowledge about the biogenesis and regulation of tasiRNAs in M. polymorpha., (© The Author(s) 2024.

- Abstract
As a model plant for bryophytes, Marchantia polymorpha offers insights into the role of RNA silencing in aiding early land plants navigate the challenges posed by high-temperature environments. Genomic analysis revealed unique ARGONAUTE1 ortholog gene (MpAGO1) in M. polymorpha that is regulated by two species-specific microRNAs (miRNAs), miR11707.1 and miR11707.2. Comparative studies of small RNA profiles from M. polymorpha cellular and MpAGO1 immunoprecipitation (MpAGO1-IP) profiles at various temperatures, along with analyses of Arabidopsis AGO1 (AtAGO1), revealed that MpAGO1 has a low-selectivity for a diverse range of small RNA species than AtAGO1. Protein structural comparisons revealed no discernible differences in the MID domains of MpAGO1 and AtAGO1, suggesting the complexity of miRNA species specificity and necessitating further exploration. Small RNA profiling and size exclusion chromatography have pinpointed a subset of M. polymorpha miRNAs, notably miR11707, that remain in free form within the cell at 22°C but are loaded into MpAGO1 at 28°C to engage in RNA silencing. Investigations into the mir11707 gene editing (mir11707ge) mutants provided evidence of the regulation of miR11707 in MpAGO1. Notably, while MpAGO1 mRNA expression decreases at 28°C, the stability of the MpAGO1 protein and its associated miRNAs is essential for enhancing the RISC activity, revealing the importance of RNA silencing in enabling M. polymorpha to survive thermal stress. This study advances our understanding of RNA silencing in bryophytes and provides groundbreaking insights into the evolutionary resilience of land plants to climatic adversities., (© The Author(s) 2024.

- Abstract
Introduction: Neonatal respiratory failure (NRF) is a serious condition that often has high mortality and morbidity, effective interventions can be delivered in the future by identifying the risk factors associated with morbidity and mortality. However, recent advances in respiratory support have improved neonatal intensive care units (NICUs) care in China. We aimed to provide an updated review of the clinical profile and outcomes of NRF in the Jiangsu province., Methods: Infants treated for NRF in the NICUs of 28 hospitals between March 2019 and March 2022 were retrospectively reviewed. Data collected included baseline perinatal and neonatal parameters, NICU admission- and treatment-related data, and patient outcomes in terms of mortality, major morbidity, and survival without major morbidities., Results: A total of 5548 infants with NRF were included in the study. The most common primary respiratory disorder was respiratory distress syndrome (78.5%). NRF was managed with non-invasive and invasive respiratory support in 59.8% and 14.5% of patients, respectively. The application rate of surfactant therapy was 38.5%, while that of neonatal extracorporeal membrane oxygenation therapy was 0.2%. Mortality and major morbidity rates of 8.5% and 23.2% were observed, respectively. Congenital anomalies, hypoxic-ischemic encephalopathy, invasive respiratory support only and inhaled nitric oxide therapy were found to be significantly associated with the risk of death. Among surviving infants born at < 32 weeks of gestation or with a birth weight < 1500 g, caffeine therapy and repeat mechanical ventilation were demonstrated to significantly associate with increased major morbidity risk., Conclusion: Our study demonstrates the current clinical landscape of infants with NRF treated in the NICU, and, by proxy, highlights the ongoing advancements in the field of perinatal and neonatal intensive care in China., (© 2024.

- Abstract
To investigate the role and potential mechanism of serine/threonine kinase 36 (STK36) in docetaxel resistance-prostate cancer (PCa). The expression of STK36 in PCa and the correlation with clinicopathological characteristics of PCa patients were analyzed using the data from different databases and tissue microarrays. To investigate the role of STK36 on cell proliferation, invasion, and migration, STK36 was overexpressed and silenced in DU-145 and PC-3 cell lines. Cell counting kit-8 (CCK8) was used to test cell proliferation. Cell invasion and migration were detected by cell wound scratch assay and trans well, respectively. The expression profile of STK36, E-Cadherin, and Vimentin was analyzed by Western blot. Cell apoptosis was detected by the TUNEL assay. STK36 expression was upregulated in PCa tissue compared with adjacent benign PCa tissue; it was higher in patients with advanced stages compared with lower stages and was significantly correlated with decreased overall survival. Up-regulation of STK36 significantly promoted the proliferation, invasion, and migration of DU-145 and PC-3 cells and compensated for the suppression caused by docetaxel treatment in vitro. A striking apoptosis inhibition could be observed when dealing with docetaxel, although the apoptosis of DU-145 and PC-3 cells was not affected by the STK36 exclusive overexpression. Besides, E-Cadherin expression was restrained while the expression levels of vimentin were all enhanced. The knockdown of STK36 reversed the above process. STK36 up-regulation could accelerate the biological behavior and docetaxel resistance of PCa by epithelial-mesenchymal transition (EMT) activation. STK36 may be potentially used as a target in PCa resolvent with docetaxel., (© 2024. The Author(s).)

- Abstract
The authors present the methods and outcomes from six institutes where M-Tang repairs with early active flexion exercise are used for zone 2 digital flexor tendon repair. The authors had close to zero repair ruptures, and few digits needed tenolysis. The excellent to good results are generally between 80% and 90%. In the pandemic period, less stringent therapy supervision might have allowed some patients to move too aggressively, with repair ruptures not seen before the pandemic in one institute. In Nantong, Yixing, and Saint John, the rupture incidence is zero to 1%. In Florence and Heidelberg, the rupture incidence was 3%., (Copyright © 2022 Elsevier Inc. All rights reserved.)

- Abstract
There are growing concerns about the neurodevelopmental toxicity of polybrominated diphenyl ethers (PBDEs), but the toxicological phenotypes and mechanisms are not well elucidated. Here, zebrafish (Danio rerio) were exposed to 2,2',4,4'-tetrabromodiphenyl ether (BDE-47) from 4 to 72 h post-fertilization (hpf). The results showed that BDE-47 stimulated the production of dopamine and 5-hydroxytryptamine, but inhibited expression of Nestin, GFAP, Gap43, and PSD95 in 24 hpf embryos. Importantly, we unraveled the inhibitory effects of BDE-47 on neural crest-derived melanocyte differentiation and melanin syntheses process, evidenced by disrupted expression of wnt1, wnt3, sox10, mitfa, tyrp1a, tyrp1b, tryp2, and oca2 gene in 72 hpf embryos and decreased tyrosinase activities in embryos at 48 and 72 hpf. The transcriptional activities of myosin VAa, kif5ba, rab27a, mlpha, and cdc42 genes, which are associated with intracellular transport process, were also disturbed during zebrafish development. Ultimately, these alterations led to fast spontaneous movement and melanin accumulation deficit in zebrafish embryos upon BDE-47 exposure. Our results provide an important extension for understanding the neurodevelopmental effects of PBDEs and facilitate the comprehensive evaluation of neurotoxicity in embryos., (© 2023.

- Abstract
BACKGROUND Pancreatic ductal adenocarcinoma (PDAC) accounts for 85% of pancreatic carcinoma cases. Patients with PDAC have a poor prognosis. The lack of reliable prognostic biomarkers makes treatment challenging for patients with PDAC. Using a bioinformatics database, we sought to identify prognostic biomarkers for PDAC. MATERIAL AND METHODS Using proteomic analysis of the Clinical Proteomics Tumor Analysis Consortium (CPTAC) database, we were able to identify core differential proteins between early and advanced pancreatic ductal adenocarcinoma tissue, and then we used survival analysis, Cox regression analysis, and area under the ROC curves to screen for more significant differential proteins. Additionally, the Kaplan-Meier plotter database was utilized to determine the relationship between prognosis and immune infiltration in PDAC. RESULTS We identified 378 differential proteins in early (n=78) and advanced stages (n=47) of PDAC (P<0.05). PLG, COPS5, FYN, ITGB3, IRF3, and SPTA1 served as independent prognostic factors of patients with PDAC. Patients with higher COPS5 expression had shorter overall survival (OS) and recurrence-free survival, and those with higher PLG, ITGB3, and SPTA1, and lower FYN and IRF3 expression had shorter OS. More importantly, COPS5, IRF3 were negatively associated with macrophages and NK cells, but PLG, FYN, ITGB3, and SPTA1 were positively related to the expression of CD8+ T cells and B cells. COPS5 affected the prognosis of PDAC patients by acting on B cells, CD8+ T cells, macrophages, and NK cells immune infiltration, while PLG, FYN, ITGB3, IRF3, and SPTA1 affected PDAC patient prognosis through some immune cells. CONCLUSIONS PLG, COPS5, FYN, IRF3, ITGB3 and SPTA1 could be potential immunotherapeutic targets and valuable prognostic biomarkers of PDAC.

- Abstract
Background: To investigate the mechanism of RNA silencing suppression, the genetic transformation of viral suppressors of RNA silencing (VSRs) in Arabidopsis integrates ectopic VSR expression at steady state, which overcomes the VSR variations caused by different virus infections or limitations of host range. Moreover, identifying the insertion of the transgenic VSR gene is necessary to establish a model transgenic plant for the functional study of VSR., Methods: Developing an endogenous AGO1-based in vitro RNA-inducing silencing complex (RISC) assay prompts further investigation into VSR-mediated suppression. Three P1/HC-Pro plants from turnip mosaic virus (TuMV) (P1/HC-Pro
Tu ), zucchini yellow mosaic virus (ZYMV) (P1/HC-ProZy ), and tobacco etch virus (TEV) (P1/HC-ProTe ) were identified by T-DNA Finder and used as materials for investigations of the RISC cleavage efficiency., Results: Our results indicated that the P1/HC-ProTu plant has slightly lower RISC activity than P1/HC-ProZy plants. In addition, the phenomena are consistent with those observed in TuMV-infected Arabidopsis plants, which implies that HC-ProTu could directly interfere with RISC activity., Conclusions: In this study, we demonstrated the application of various plant materials in an in vitro RISC assay of VSR-mediated RNA silencing suppression., (© 2023.

- Abstract
Vocal fold (VF) scarring results from injury to the unique layered structure and is one of the main reasons for long-lasting dysphonia. A minimally invasive procedure with injectable hydrogels is a promising method for therapy. However, current surgical techniques or standard injectable fillers do not yield satisfactory outcomes. In this work, an injectable hybrid hydrogel consisting of oxide hyaluronic acid and hydrazide-modified waterborne polyurethane emulsion was injected precisely into the injury site and cross-linked in situ by a dynamic hydrazone bond. The prepared hydrogel displays excellent injectability and self-healing ability, showing favorable biocompatibility and biodegradability to facilitate endogenous newborn cell migration and growth for tissue regeneration. With the aim of evaluating the antifibrosis and regeneration capacity of the hybrid hydrogel in the VF scarring model, the morphology and vibration characteristics of VFs, inflammatory response, and healing status were collected. The hybrid hydrogel can decrease the inflammation and increase the ratio of collagen III/collagen I to heal damaged scar-free tissue. Fascinatingly, the mucosal wave oscillations of healing VF by injecting the hybrid hydrogel were vibrated like the normal VF, achieving functional restoration. This work highlights the utility of hybrid hydrogels consisting of synthetic biodegradable waterborne polyurethane emulsions and natural hyaluronic acid as promising biomaterials for scarless healing of damaged VFs.

- Abstract
Objectives: To investigate the current status of antibiotic use in very low birth weight/extremely low birth weight infants in Jiangsu Province of China, and to provide a clinical basis for the quality and improvement of antibiotic management in the neonatal intensive care unit (NICU)., Methods: A retrospective analysis was performed on the data on general conditions and antibiotic use in the very low birth weight/extremely low birth weight infants who were admitted to 15 hospitals of Jiangsu Province from January 1, 2019 to December 31, 2020. A questionnaire containing 10 measures to reduce antibiotic use was designed to investigate the implementation of these intervention measures., Results: A total of 1 920 very low birth weight/extremely low birth weight infants were enrolled, among whom 1 846 (96.15%) were treated with antibiotic, and the median antibiotic use rate (AUR) was 50/100 patient-days. The AUR ranged from 24/100 to 100/100 patient-days in the 15 hospitals. After adjustment for the confounding factors including gestational age, birth weight, and neonatal critical score, the Poisson regression analysis showed that there was a significant difference in the adjusted AUR (aAUR) among the hospitals ( P< 0.01). The investigation results showed that among the 10 measures to reduce antibiotic use, 8 measures were implemented in less than 50% of these hospitals, and the number of intervention measures implemented was negatively correlated with aAUR ( r
s =-0.564, P =0.029)., Conclusions: There is a high AUR among the very low birth weight/extremely low birth weight infants in the 15 hospitals of Jiangsu Province, with a significant difference among hospitals. The hospitals implementing a relatively few measures to reduce antibiotic use tend to have a high AUR. It is expected to reduce AUR in very low birth weight/extremely low birth weight infants by promoting the quality improvement of antibiotic use management in the NICU.- Published

- Abstract
Premise: Transient gene expression systems are powerful tools for studying gene interactions in plant species without available or stable genetic transformation protocols. We optimized a petal protoplast transformation protocol for Sinningia speciosa , a model plant, to study the development of floral symmetry., Methods and Results: A high yield of petal protoplasts was obtained using a 6-h enzyme digestion in a solution of 1.5% cellulase and 0.4% macerozyme. Modest transfection efficiency (average 41.4%) was achieved. The viability of the transfected protoplasts remained at more than 90%. A fusion of green fluorescent protein and CYCLOIDEA (SsCYC), the Teosinte branched 1 / Cincinnata / Proliferating cell factor transcription factor responsible for floral symmetry, was subcellularly localized inside the nuclei of the protoplasts. Transiently overexpressing SsCYC indicates the success of this system, which resulted in the predicted increased (but nonsignificant) expression of its known target RADIALIS ( SsRAD1 ), consistent with gene network expectations., Conclusions: The transient transfection system presented herein can be effectively used to study gene-regulatory interactions in Gesneriaceae species., (© 2022 The Authors.

- Abstract
Objectives: To investigate the preadmission follow-up condition of neonates hospitalized due to severe hyperbilirubinemia after discharge from the department of obstetrics and the influencing factors for follow-up compliance., Methods: A multicenter retrospective case-control study was performed for the cases from the multicenter clinical database of 12 units in the Quality Improvement Clinical Research Cooperative Group of Neonatal Severe Hyperbilirubinemia in Jiangsu Province of China from January 2019 to April 2021. According to whether the follow-up of neonatal jaundice was conducted on time after discharge from the department of obstetrics, the neonates were divided into two groups: good follow-up compliance and poor follow-up compliance. The multivariate logistic regression model was used to identify the influencing factors for follow-up compliance of the neonates before admission., Results: A total of 545 neonates with severe hyperbilirubinemia were included in the study, with 156 neonates (28.6%) in the good follow-up compliance group and 389 (71.4%) in the poor follow-up compliance group. The multivariate logistic regression analysis showed that low gestational age at birth, ≥10% reduction in body weight on admission compared with birth weight, history of phototherapy of siblings, history of exchange transfusion of siblings, Rh(-) blood type of the mother, a higher educational level of the mother, the use of WeChat official account by medical staff to remind of follow-up before discharge from the department of obstetrics, and the method of telephone notification to remind of follow-up after discharge were associated with the increase in follow-up compliance ( P <0.05)., Conclusions: Poor follow-up compliance is observed for the neonates with severe hyperbilirubinemia after discharge from the department of obstetrics, which suggests that it is necessary to further strengthen the education of jaundice to parents before discharge and improve the awareness of jaundice follow-up. It is recommended to remind parents to follow up on time by phone or WeChat official account.

- Abstract
Objectives: To explore the optimal maintenance dose of caffeine citrate for preterm infants requiring assisted ventilation and caffeine citrate treatment., Methods: A retrospective analysis was performed on the medical data of 566 preterm infants (gestational age ≤34 weeks) who were treated and required assisted ventilation and caffeine citrate treatment in the neonatal intensive care unit of 30 tertiary hospitals in Jiangsu Province of China between January 1 and December 31, 2019. The 405 preterm infants receiving high-dose (10 mg/kg per day) caffeine citrate after a loading dose of 20 mg/kg within 24 hours after birth were enrolled as the high-dose group. The 161 preterm infants receiving low-dose (5 mg/kg per day) caffeine citrate were enrolled as the low-dose group., Results: Compared with the low-dose group, the high-dose group had significant reductions in the need for high-concentration oxygen during assisted ventilation ( P =0.044), the duration of oxygen inhalation after weaning from noninvasive ventilation ( P <0.01), total oxygen inhalation time during hospitalization ( P <0.01), the proportion of preterm infants requiring noninvasive ventilation again ( P <0.01), the rate of use of pulmonary surfactant and budesonide ( P <0.05), and the incidence rates of apnea and bronchopulmonary dysplasia ( P <0.01), but the high-dose group had a significantly increased incidence rate of feeding intolerance ( P =0.032). There were no significant differences between the two groups in the body weight change, the incidence rates of retinopathy of prematurity, intraventricular hemorrhage or necrotizing enterocolitis, the mortality rate, and the duration of caffeine use ( P >0.05)., Conclusions: This pilot multicenter study shows that the high maintenance dose (10 mg/kg per day) is generally beneficial to preterm infants in China and does not increase the incidence rate of common adverse reactions. For the risk of feeding intolerance, further research is needed to eliminate the interference of confounding factors as far as possible.

- Abstract
The establishment of dorsal-ventral (DV) petal asymmetry is accompanied by differential growth of DV petal size, shape, and color differences, which enhance ornamental values. Genes involved in flower symmetry in Sinningia speciosa have been identified as CYCLOIDEA ( SsCYC ), but which gene regulatory network (GRN) is associated with SsCYC to establish DV petal asymmetry is still unknown. To uncover the GRN of DV petal asymmetry, we identified 630 DV differentially expressed genes (DV-DEGs) from the RNA-Seq of dorsal and ventral petals in the wild progenitor, S. speciosa 'ES'. Validated by qRT-PCR, genes in the auxin signaling transduction pathway, SsCYC , and a major regulator of anthocyanin biosynthesis were upregulated in dorsal petals. These genes correlated with a higher endogenous auxin level in dorsal petals, with longer tube length growth through cell expansion and a purple dorsal color. Over-expression of SsCYC in Nicotiana reduced petal size by regulating cell growth, suggesting that SsCYC also controls cell expansion. This suggests that auxin and SsCYC both regulate DV petal asymmetry. Transiently over-expressed SsCYC , however, could not activate most major auxin signaling genes, suggesting that SsCYC may not trigger auxin regulation. Whether auxin can activate SsCYC or whether they act independently to regulate DV petal asymmetry remains to be explored in the future.

- Abstract
The current clinical methods of flexor tendon repair are remarkably different from those used 20 years ago. This article starts with a review of the current methods, followed by presentation of past experience and current status of six eminent hand surgery units from four continents/regions. Many units are using, or are moving toward using, the recent strong (multi-strand) core suture method together with a simpler peripheral suture. Venting of the critical pulleys over less than 2 cm length is safe and favours functional recovery. These repair and recent motion protocols lead to remarkably more reliable repairs, with over 80% good or excellent outcomes achieved rather consistently after Zone 2 repair along with infrequent need of tenolysis. Despite slight variations in repair methods, they all consider general principles and should be followed. Outcomes of Zone 2 repairs are not dissimilar to those in other zones with very low to zero incidence of rupture.

- Abstract
The P1/HC-Pro viral suppressor of potyvirus suppresses posttranscriptional gene silencing (PTGS). The fusion protein of P1/HC-Pro can be cleaved into P1 and HC-Pro through the P1 self-cleavage activity, and P1 is necessary and sufficient to enhance PTGS suppression of HC-Pro. To address the modulation of gene regulatory relationships induced by turnip mosaic virus (TuMV) P1/HC-Pro (P1/HC-Pro
Tu ), a comparative transcriptome analysis of three types of transgenic plants ( P1Tu , HC-ProTu , and P1/HC-ProTu ) were conducted using both high-throughput (HTP) and low-throughput (LTP) RNA-Seq strategies. The results showed that P1/HC-ProTu disturbed the endogenous abscisic acid (ABA) accumulation and genes in the signaling pathway. Additionally, the integrated responses of stress-related genes, in particular to drought stress, cold stress, senescence, and stomatal dynamics, altered the expressions by the ABA/calcium signaling. Crosstalk among the ABA, jasmonic acid, and salicylic acid pathways might simultaneously modulate the stress responses triggered by P1/HC-ProTu . Furthermore, the LTP network analysis revealed crucial genes in common with those identified by the HTP network in this study, demonstrating the effectiveness of the miniaturization of the HTP profile. Overall, our findings indicate that P1/HC-ProTu -mediated suppression in RNA silencing altered the ABA/calcium signaling and a wide range of stress responses.- Published

- Abstract
Objective: To evaluate the effect on the maturation of arteriovenous fistulas (AVFs) when using the internal branch of the cephalic vein compared with the main branch of the cephalic vein., Methods: The study enrolled patients with end-stage renal disease and divided them into an internal branch group (AVF constructed using the internal branch of the cephalic vein) or a main branch group (AVF constructed using the main branch of the cephalic vein). The surgical outcomes including complications were observed in these patients after 12 weeks., Results: Thirty-two patients with end-stage renal disease were included in the study. There were 16 patients in each group. The demographic and clinical characteristics were not significantly different between the two groups. The diameter of the arteries and veins were not significantly different between the two groups before the operation. In the internal branch group, significantly more ( n = 7) patients failed to mature or required surgical intervention compared with the main branch group ( n = 1)., Conclusion: For veins of the same diameter, these findings suggest that constructing AVFs using the main branch of the cephalic vein instead of the internal branch was more suitable for patients with end-stage renal disease requiring haemodialysis.

- Abstract
Cadmium is one of the most toxic heavy metal contaminants in soils and water bodies and poses a serious threat to ecosystems and humans. However, cadmium is also an important resource widely used in many industries. The recovery of cadmium in the form of high-value products is considered as an ideal disposal strategy for Cd-contaminated environments. In this work, Pistia stratiotes was used to recycle cadmium from wastewaters through phytoaccumulation and then transformed into carbon-supported cadmium sulfide photocatalyst (CdS@C) through carbonization and hydrothermal reaction. The CdS@C photocatalyst contained a mixture of cubic and hexagonal CdS with lower band gap energy (2.14 eV) and high electron-hole separation efficiency, suggesting an excellent photoresponse ability and photocatalytic efficiency. The impressive stability and photocatalytic performance of CdS@C were demonstrated in efficient photodegradation of organic pollutants. •OH and O
2 •- were confirmed as the major active species for organic pollutants degradation during CdS@C photocatalysis. This work provides new insights into addressing Cd contaminated water bodies and upcycling in the form of photocatalyst., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Li, Zhang, Pan, Liao, Xiong, Chen, Huang, Pan and Chen.)- Published

- Abstract
In plants, HEN1-facilitated methylation at 3' end ribose is a critical step of small-RNA (sRNA) biogenesis. A mutant of well-studied Arabidopsis HEN1 (AtHEN1), hen1-1 , showed a defective developmental phenotype, indicating the importance of sRNA methylation. Moreover, Marchantia polymorpha has been identified to have a HEN1 ortholog gene (Mp HEN1 ); however, its function remained unfathomed. Our in vivo and in vitro data have shown MpHEN1 activity being comparable with AtHEN1, and their substrate specificity towards duplex microRNA (miRNA) remained consistent. Furthermore, the phylogenetic tree and multiple alignment highlighted the conserved molecular evolution of the HEN1 family in plants. The P1/HC-Pro of the turnip mosaic virus (TuMV) is a known RNA silencing suppressor and inhibits HEN1 methylation of sRNAs. Here, we report that the HC-Pro physically binds with AtHEN1 through FRNK motif, inhibiting HEN1's methylation activity. Moreover, the in vitro EMSA data indicates GST-HC-Pro of TuMV lacks sRNA duplex-binding ability. Surprisingly, the HC-Pro also inhibits MpHEN1 activity in a dosage-dependent manner, suggesting the possibility of interaction between HC-Pro and MpHEN1 as well. Further investigations on understanding interaction mechanisms of HEN1 and various HC-Pros can advance the knowledge of viral suppressors.

- Abstract
Magnetic Fe₂O3/Fe₃O4@SiO₂ nanocomposites were prepared via the citric-alcohol solution combustion process. The obtained nanocomposites were characterized with SEM, XRD, VSM, TEM, EDS, HRTEM, and FTIR techniques. The results revealed that the magnetic Fe₂O₃/Fe₃O₄@SiO₂ nanocomposites were successfully obtained with the average grain size of 87 nm and the saturation magnetization of 36 emu/g. After the surface of magnetic Fe₂O₃/Fe₃O₄@SiO₂ nanocomposites was functionalized by amino group, the amino-functionalized Fe₂O₃/Fe₃O₄@SiO₂-NH₂ nanocomposites were loaded onto graphene oxide based on Mitsunobu reaction. Subsequently, the cellulase was immobilized onto Fe₂O₃/Fe₃O₄@SiO₂-NH-GO nanocomposites by a glutaraldehyde-mediated Schiff base reaction. The immobilization conditions were optimized by adjusting the pH, temperature, and cellulase dose. The results revealed that optimized immobilization conditions were determined to be temperature of 50 °C, pH of 5, and cellulase solution of 0.1 mL. 97.3% cellulase were successfully immobilized under the optimal conditions. The catalytic performances of the immobilized cellulase were also evaluated. The maximum activity was achieved at pH 4, and 50 °C with cellulase solution of 0.4 mL.

- Abstract
Background: The purpose of this study was to compare the clinical efficacy of robotic right colectomy (RRC) and laparoscopic right colectomy (LRC) in the treatment of right colon tumor., Methods: We systematically searched PubMed, Web of science, EMBASE ClinicalTrials.gov and Cochrane Central Register for studies (studies published between January 2011 and June 2020). The included studies compared the clinical efficacy of RRC and LRC in the treatment of right colon tumor, and analyzed the perioperative data., Results: Our meta-analysis included 10 studies involving 1180 patients who underwent 2 surgical procedures, RRC and LRC. This study showed that compared with LRC, there was no significant difference in first flatus passage (weighted mean difference [WMD]: -0.37, 95% CI: -1.09-0.36, P = .32), hospital length of stay (WMD: -0.23, 95% CI: -0.73-0.28, P = .32), reoperation (OR: 1.66, 95% CI: 0.67-4.10, P = .27), complication (OR: 0.83, 95% CI: 0.60-1.14, P = .25), mortality (OR: 0.45, 95% CI: 0.02-11.22, P = .63), wound infection (OR: 0.65, 95% CI: 0.34-1.25, P = .20), and anastomotic leak (OR: 0.73, 95% CI: 0.33-1.63, P = .44). This study showed that compared with LRC, the lymph nodes retrieved (WMD: 1.47, 95% CI: -0.00-2.94, P = .05) of RRC were similar, with slight advantages, and resulted in longer operative time (WMD: 65.20, 95% CI: 53.40-77.01, P < .00001), less estimated blood loss (WMD: -13.43, 95% CI: -20.65-6.21, P = .0003), and less conversion to open surgery (OR: 0.30, 95% CI: 0.17-0.54, P < .0001)., Conclusions: RRC is equivalent to LRC with respect to first flatus passage, hospital length of stay, reoperation, complication, and results in less conversion to LRC., Competing Interests: The authors have no funding and conflicts of interest to disclose., (Copyright © 2021 the Author(s).

- Abstract
Objectives: To study the survival rate and the incidence of complications of very preterm infants and the factors influencing the survival rate and the incidence of complications., Methods: The medical data of the very preterm infants with a gestational age of <32 weeks and who were admitted to the Department of Neonatology in 11 hospitals of Jiangsu Province in China from January 2018 to December 2019 were retrospectively reviewed. Their survival rate and the incidence of serious complications were analyzed. A multivariate logistic regression analysis was used to evaluate the risk factors for death and serious complications in very preterm infants., Results: A total of 2 339 very preterm infants were enrolled, among whom 2 010 (85.93%) survived and 1 507 (64.43%) survived without serious complications. The groups with a gestational age of 22-25
+6 weeks, 26 - 26+6 weeks, 27-27+6 weeks, 28 - 28+6 weeks, 29 - 29+6 weeks, 30 - 30+6 weeks, and 31-31+6 weeks had a survival rate of 32.5%, 60.6%, 68.0%, 82.9%, 90.1%, 92.3%, and 94.8% respectively. The survival rate tended to increase with the gestational age ( P <0.05) and the survival rate without serious complications in each gestational age group was 7.5%, 18.1%, 34.5%, 52.2%, 66.7%, 75.7%, and 81.8% respectively, suggesting that the survival rate without serious complications increased with the gestational age ( P <0.05). The multivariate logistic regression analysis showed that high gestational age, high birth weight, and prenatal use of glucocorticoids were protective factors against death in very preterm infants ( P <0.05), and 1-minute Apgar score ≤3 was a risk factor for death in very preterm infants ( P <0.05); high gestational age and high birth weight were protective factors against serious complications in very preterm infants who survived ( P <0.05), while 5-minute Apgar score ≤3 and maternal chorioamnionitis were risk factors for serious complications in very preterm infants who survived ( P <0.05)., Conclusions: The survival rate is closely associated with gestational age in very preterm infants. A low 1-minute Apgar score (≤3) may increase the risk of death in very preterm infants, while high gestational age, high birth weight, and prenatal use of glucocorticoids are associated with the reduced risk of death. A low 5-minute Apgar score (≤3) and maternal chorioamnionitis may increase the risk of serious complications in these infants, while high gestational age and high birth weight may reduce the risk of serious complications.- Published

- Abstract
Background: Degenerative spine disease is common in athletes and can progress to requiring surgical intervention. Traditional open surgical techniques necessitate prolonged recovery time and time away from play. Newly developed endoscopic surgical techniques may promote faster healing and recovery, and increased return to play. The goal of this paper is to summarize the current evidence in return to play after spine surgery and to present our series of 3 athletes who underwent endoscopic spine surgery., Methods: A complete search of all PubMed indexed articles pertaining to spine surgery in athletes was conducted. This was supplemented by a 3-patient case series of our own endoscopic spine experience in athletes., Results: There are no current widely accepted guidelines for return to play after spinal surgery. The best evidence available cites a return to play of 81% at 5.2-8.7 months after traditional open and minimally invasive surgery, and endoscopic surgery produces an average 88% return to play rate at 3 months., Conclusions: Although return to play can vary widely, case-based evidence as well as biomechanical principles support endoscopic spine surgery as a viable surgical modality for the treatment of spinal pathologies in athletes., (Copyright © 2020 Elsevier Inc.

30. New Adsorption Models for Entirely Describing the Adsorption Isotherm and Heat of Methane in Heterogeneous Nanopore Structures of Coal.

- Abstract
To understand the adsorption mechanism of methane in heterogeneous nanopore structures of coal, integral adsorption models based on linear, exponential, hyperbolic and quadratic energy distribution functions are established. The adsorption energy domain of the new models is assumed to be a finite interval. These new adsorption models can describe both the adsorption isotherm and the adsorption heat. A volumetric method of adsorption with a microcalorimetry system is used to measure the adsorption isotherms and integral heat, and then the parameters of the new models are obtained by fitting the experimental data. Since the adsorption heat can be different for different adsorption models, it is necessary to fit the adsorption isotherms and heat simultaneously. The fitting results of the adsorption isotherms and heat show that the new models are able to describe the experimental data better than the Langmuir model. By comparing the fitting results and the effective range of adsorption energy of the different adsorption models, it is shown that the exponential energy distribution function is the most reasonable model for methane adsorption in coals, which can be used to evaluate the energetic heterogeneity of nanopores in coal samples. The decreasing exponential energy distributions of three coal samples indicate that a larger adsorption energy corresponds to fewer adsorption sites in the coal samples. The proportion of high adsorption energy is related to the micro-nanopore volume in the coal samples.

- Abstract
2,2,4,4-tetrabromodiphenyl ether (BDE-47) has received considerable attention because of its high detection level in biological samples and potential developmental toxicity. Here, using zebrafish (Danio rerio) as the experimental animal, we investigated developmental effects of BDE-47 and explored the potential mechanism. Zebrafish embryos at 4 h post-fertilization (hpf) were exposed to 0.312, 0.625 and 1.25 mg/L BDE-47 to 74-120 hpf. We found that BDE-47 instigated a dose-related developmental toxicity, evidenced by reduced embryonic survival and hatching rate, shortened body length and increased aberration rate. Meanwhile, higher doses of BDE-47 reduced mitochondrial membrane potential and ATP production but increased apoptosis in zebrafish embryos. Expression of genes involved in mitochondrial oxidative phosphorylation (OXPHOS) (ndufb8, sdha, uqcrc1, cox5ab and atp5fal) were negatively related to BDE-47 doses in zebrafish embryos. Moreover, exposure to BDE-47 at 0.625 or 1.25 mg/L impaired mitochondrial biogenesis and mitochondrial dynamics. Our data further showed that BDE- 47 exposure induced excessive reactive oxygen species (ROS) and oxidative stress, which was accompanied by the activation of c-Jun N-terminal Kinase (JNK). Antioxidant NAC and JNK inhibition could mitigate apoptosis in embryos and improve embryonic development in BDE-47-treated zebrafish, suggesting the involvement of ROS/JNK pathway in embryonic developmental changes induced by BDE-47. Altogether, our data suggest here that developmental toxicity of BDE-47 may be associated with mitochondrial ROS-mediated JNK signaling in zebrafish embryo., Competing Interests: Declaration of competing interest This work was supported by the National Natural Science Foundation of China (31672648, 31671033, 31871013, China); the University Natural Science Foundation of Jiangsu Province (18KJB330001, China); the Open Fund of Jiangsu Key Laboratory for Eco-Agricultural Biotechnology Around Hongze Lake (HZHLAB1707, China).

- Abstract
The objective of this study was to explore the neuroprotective molecular mechanisms of erythropoietin (EPO) in rats following spinal cord injury (SCI). First, a standard SCI model was established. After drug or saline treatment was administered, locomotor function was evaluated in rats using the Basso, Beattie, and Bresnahan (BBB) locomotor rating scale. H&E, Nissl, and TUNEL staining were performed to assess the ratio of cavities, number of motor neurons, and apoptotic cells in the damaged area. The relative protein and mRNA expressions were examined using western blot and qRT-PCR analyses, and the inflammatory markers, axon special protein, and neuromuscular junctions (NMJs) were detected by immunofluorescence. Both doses of EPO notably improved locomotor function, but high-dose EPO was more effective than low-dose EPO. Moreover, EPO reduced the cavity ratio, cell apoptosis, and motor neuron loss in the damaged area, but enhanced the autophagy level and extracellular-regulated protein kinase (ERK) activity. Treatment with an ERK inhibitor significantly prevented the effect of EPO on SCI, and an activator mimicked the benefits of EPO. Further investigation revealed that EPO promoted SCI-induced autophagy via the ERK signaling pathway. EPO activates autophagy to promote locomotor function recovery in rats with SCI via the ERK signaling pathway.

- Abstract
Objective: To investigate the incidence of severe neonatal hyperbilirubinemia and the management on the treatment and follow-up of this disease in Jiangsu Province, China., Methods: The neonates with severe hyperbilirubinemia who were admitted to 13 hospitals in Jiangsu Province from January to December, 2018, were enrolled as subjects. A retrospective analysis was performed on their mediacal data and follow-up data., Results: In 2018, 740 neonates with severe hyperbilirubinemia were reported from the 13 hospitals in Jiangsu Province, accounting for 2.70% (740/27 386) of the total number of neonates admitted to the department of neonatology. Among these neonates, 620 (83.8%) had severe hyperbilirubinemia, 106 (14.3%) had extremely severe hyperbilirubinemia, and 14 (1.9%) had hazardous hyperbilirubinemia. Four neonates (0.5%) were diagnosed with acute bilirubin encephalopathy. A total of 484 neonates (65.4%) were readmitted due to severe hyperbilirubinemia after discharge from the delivery institution, with a median age of 7 days, among whom 214 (44.2%) were followed up for jaundice at the outpatient service before readmission, with a median age of 6 days at the first time of outpatient examination. During hospitalization, 211 neonates (28.5%) underwent cranial MRI examinations, among whom 85 (40.3%) had high T1WI signal in the bilateral basal ganglia and the globus pallidus; 238 neonates (32.2%) underwent brainstem auditory evoked potential examinations, among whom 14 (5.9%) passed only at one side and 7 (2.9%) failed at both sides. The 17 neonates with acute bilirubin encephalopathy or hazardous hyperbilirubinemia were followed up. Except one neonate was lost to follow-up, and there were no abnormal neurological symptoms in the other neonates., Conclusions: Neonates with severe hyperbilirubinemia account for a relatively high proportion of the total number of neonates in the department of neonatology. Jaundice monitoring and management after discharge from delivery institutions need to be strengthened. For neonates with severe hyperbilirubinemia, relevant examinations should be carried out more comprehensively during hospitalization and these neonates should be followed up comprehensively and systematically after discharge.

- Abstract
Background: Severe hyponatremia is considered a rare complication of pituitrin, which is widely used for the treatment of pulmonary hemorrhage. However, the management of pituitrin-associated hyponatremia can be challenging because a rapid correction of hyponatremia may cause the development of osmotic demyelination syndrome, resulting in life-threatening neurological injuries., Case Summary: A 20-year-old Chinese man with massive hemoptysis developed symptomatic hyponatremia (116 mmol/L) after therapy by a continuous intravenous drip of pituitrin. To normalize his serum sodium, a hypertonic saline infusion was applied for 3 d, and the pituitrin administration was stopped concurrently. Then, an overly rapid increase in serum sodium level (18 mmol/L in 24 h) was detected after treatment. One day later, the patient experienced a sudden onset of generalized tonic-clonic seizures, as well as subsequent dysarthria and dystonia. Magnetic resonance imaging revealed increased signal intensity in the bilateral symmetric basal ganglia on the T2-weighted images, compatible with a diagnosis of extrapontine myelinolysis. The patient received an intravenous administration of high-dose corticosteroids, rehabilitation, and neurotrophic therapy. Finally, his clinical abnormalities were vastly improved, and he was discharged with few residual symptoms., Conclusion: Physicians should be fully aware that pituitrin can cause profound hyponatremia and its correction must be performed at a controlled rate to prevent the development of osmotic demyelination syndrome., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflict of interest., (©The Author(s) 2020.

Purpose: The aim of this current review was to confirm the efficacy of intra-articular steroid therapy (IAST) for patients with hip osteoarthritis (OA) and discuss the duration and influential factors of IAST., Methods: Online databases (Medline, EMBASE, and Web of Science) were searched from inception to May 2019. Both randomized controlled trials (RCTs) and noncontrolled trials assessing the efficacy of hip IAST on pain were included. Common demographics data were extracted using a standardized form. Quality was assessed on the basis of Oxford Centre for Evidence-Based Medicine 2011 Levels of Evidence., Results: 12 trials met the inclusion criteria. According to data from individual trials, IAST had significant efficacy on hip OA in both immediate and delay pain reduction, which persisted up to 12 weeks after IAST. The influences of the baseline severity of hip OA or synovitis and injection dose or volume on the clinical outcome of IAST were still controversial. The IAST appeared to be well tolerant by most of the participants., Conclusion: IAST was proved to be an efficacious therapy in both immediate and delay pain reduction for hip OA patients within 12 weeks. The longer follow-up data of efficacy and safety and potentially influential factors are still unclear and needed further confirmation., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2020 Hui-Ming Zhong et al.)

- Abstract
Phalaenopsis orchids have a spectacular floral morphology with a highly evolved lip that offers a landing platform for pollinators. The typical morphological orchid lip features are essential for the special pollination mechanism of Phalaenopsis flowers. Previously, we found that in the lip, a member of the AP2/EREBP protein family was highly expressed. Here, we further confirmed its high expression and characterized its function during lip development. Phylogenetic analysis showed that AP2/EREBP belongs to the Va2 subgroup of ERF transcription factors. We named it PeERF1. We found that PeERF1 was only expressed at stage 5, as flowers opened. This coincided with both thickening of the cuticle and development of nanoridges. We performed knockdown expression of PeERF1 using CymMV-based virus-induced gene silencing in either the AP2 conserved domain, producing PeERF1_AP2 -silenced plants, or the SHN specific domain, producing PeERF1_SHN- silenced plants. Using cryo-SEM, we found that the number of nanoridges was reduced only in the PeERF1_AP2 -silenced group. This change was found on both the abaxial and adaxial surfaces of the central lip lobe. Expression of PeERF1 was reduced significantly in PeERF1_AP2 -silenced plants. In cutin biosynthesis genes, expression of both PeCYP86A2 and PeDCR was significantly decreased in both groups. The expression of PeCYP77A4 was reduced significantly only in the PeERF1_AP2 -silenced plants. Although PeGPAT expression was reduced in both silenced plants, but to a lesser degree. The expression of PeERF1 was significantly reduced in the petal-like lip of a big-lip variant. PeCYP77A4 and PeGPAT in the lip were also reduced, but PeDCR was not . Furthermore, heterologous overexpression of PeERF1 in the genus Arabidopsis produced leaves that were shiny on the adaxial surface. Taken together, our results show that in Phalaenopsis orchids PeERF1 plays an important role in formation of nanoridges during lip epidermis development., (Copyright © 2020 Lai, Huang, Pan, Jane, Chung, Chen and Chen.)

- Abstract
We reviewed outcomes of 230 flexor tendon repairs in 27 thumbs and 203 fingers in Zone 1 and 2 over 7 years. In 2013, we used a 2-strand modified Kessler method followed by passive motion exercise in repairing flexor digitorum profundus tendon injuries in Zone 2 in 30 fingers; 24 fingers were followed, five (26%) had repair ruptures. Between 2014 and 2017, we used a 4- or 6-strand method to repair 111 flexor digitorum profundus tendons in Zone 2, followed by true early active motion. Two had repair ruptures. Among 101 fingers followed over 6 months, two fingers had tenolysis and 87 (87%) good or excellent outcomes. In 2018 to 2019, we used a 6-strand method to repair 42 flexor digitorum profundus tendons in Zone 2 with out-of-splint early active motion. None had repair ruptures or tenolysis. From 2014 to 2019, 27 flexor pollicis longus tendons were repaired in Zone 1 or 2, and 20 fingers had end-to-end flexor digitorum profundus repairs in Zone 1; none had repair ruptures or tenolysis. We conclude that a strong repair and true active motion are necessary for best outcomes of flexor tendon repairs in the thumb and fingers, and out-of-splint true active motion is safe.

- Abstract
We report the outcomes of zone 2 tendon repairs in 60 fingers using a strong core suture, sparse peripheral stitches and early active motion. From January 2014 to April 2016, we repaired 60 flexor digitorum profundus tendons with a tensioned 4-strand or 6-strand core suture and three to four peripheral stitches. The A2 or A4 pulleys were vented as necessary. Following early active flexion of the repaired tendons, no repairs ruptured and 52/60 (87%) fingers recovered to good or excellent function using the Tang criteria after follow-up of 8-33 months. We conclude that tensioned multi-strand strong core repairs only require sparse peripheral stitches and are safe for early active flexion. Standard peripheral sutures are not necessary. The core sutures should be properly tensioned to prevent gapping at tendon repair site and pulleys should be sufficiently vented to allow tendon motion. Level of evidence: IV.

43. Genetic Analysis of Floral Symmetry Transition in African Violet Suggests the Involvement of Trans-acting Factor for CYCLOIDEA Expression Shifts.

- Abstract
With the growing demand for its ornamental uses, the African violet ( Saintpaulia ionantha ) has been popular owing to its variations in color, shape and its rapid responses to artificial selection. Wild type African violet (WT) is characterized by flowers with bilateral symmetry yet reversals showing radially symmetrical flowers such as dorsalized actinomorphic (DA) and ventralized actinomorphic (VA) peloria are common. Genetic crosses among WT, DA, and VA revealed that these floral symmetry transitions are likely to be controlled by three alleles at a single locus in which the levels of dominance are in a hierarchical fashion. To investigate whether the floral symmetry gene was responsible for these reversals, orthologs of CYCLOIDEA ( CYC ) were isolated and their expressions correlated to floral symmetry transitions. Quantitative RT-PCR and in situ results indicated that dorsal-specific CYCs expression in WT S. ionantha ( SiCYC and SiCYC1B ) shifted in DA with a heterotopically extended expression to all petals, but in VA, SiCYC1s' dorsally specific expressions were greatly reduced. Selection signature analysis revealed that the major high-expressed copy of SiCYC had been constrained under purifying selection, whereas the low-expressed helper SiCYC1B appeared to be relaxed under purifying selection after the duplication into SiCYC and SiCYC1B . Heterologous expression of SiCYC in Arabdiopsis showed petal growth retardation which was attributed to limited cell proliferation. While expression shifts of SiCYC and SiCYC1B correlate perfectly to the resulting symmetry phenotype transitions in F1s of WT and DA, there is no certain allelic combination of inherited SiCYC1s associated with specific symmetry phenotypes. This floral transition indicates that although the expression shifts of SiCYC/1B are responsible for the two contrasting actinomorphic reversals in African violet, they are likely to be controlled by upstream trans-acting factors or epigenetic regulations.

- Abstract
In this paper, polyacrylonitrile/graphene composite nanofiber filaments were manufactured continuously by a homemade eight-needle electrospinning device with an auxiliary electrode. The polyacrylonitrile/graphene composite nanofiber yarns were obtained continuously by plying and twisting the composite nanofiber filaments. The structures and properties of the composite nanofiber filaments with different GP mass fractions and yarns were investigated. The results demonstrated that the maximum alignment degree of the composite nanofibers along the filament axis could reach 74.3% with 1%, and the alignment degree decreased with increasing graphene mass fraction. The diameters of the composite nanofibers were considerably smaller than those of the pure polyacrylonitrile nanofiber, and the minimum diameter was 156 nm for 1%. The conductivity of the composite nanofiber filaments was significantly enhanced by seven orders of magnitude compared with that of the pure polyacrylonitrile nanofiber filament, and the maximum value was 3.73×10-7 S/cm for 1.5%. Due to graphene agglomeration, the conductivity decreased when the mass fraction was more than 1.5%. The different number of filaments and twists were examined in detail to improve the poor mechanical properties of the nanofiber filaments. With an increase in twists, the breaking stress and strain increased initially and later decreased, and the maximum breaking stress and strain were 16.54 MPa and 26.42%, respectively. This study demonstrates the possibility of continuously and stably manufacturing polyacrylonitrile/graphene composite nanofiber yarns.

- Abstract
Objective: To explore the clinical outcomes of internal fixation or replacement for the treatment of radial head fractures through the extensor digitorum communis splitting approach., Methods: From July 2012 to May 2015, 25 patients with radial head fractures were reviewed. There were 17 males and 8 females, ranging in age from 20 to 67 years old, with a mean age of 39 years old. Twenty-one patients were treated with reconstruction of plate internal fixation, and 4 patients were treated with radial head replacement. According to Mason classification, 19 cases were type II and 6 cases were type III. All the patients underwent internal fixation or replacement through the extensor digitorum communis splitting approach. The patients were followed up clinically and radiographically until the beginning of fracture union and the entrance of function recovery of elbow motion into a plateau. The functional status of the elbow was evaluated using the Mayo Elbow Performance Index(MEPI). Radiographic signs of post-traumatic arthritis were rated according to the Broberg and Morrey system., Results: All the patients were followed up, and the average duration was 29 months (ranged, 12 to 56 months). The average range of flexion and extension was 120°, the extension was limited by 10°, and the flexion was 135°. The average forearm rotation range was 142°, pronation was 75°, supination was 67°. The mean MEPI was 93±7(ranged, 80 to 100 scores); according to the MEPI scoring criceria, 19 patients got an excellent functional result, 6 good. According to the Broberg and Morrey systems of traumatic arthritis, 19 patients were in grade 0, 6 in grade 1, and no patients in grade 2 or 3. No patients with nonunion of the radial head and failure of internal fixation were found. There were no complications of nerve or vascular injuries, and obvious limitation of elbow rotation. Heterotopic ossification around the elbow occurred in 4 cases, but the motion was not significantly limited. There were no complications such as prosthesis loosening and infection in 4 cases after radial head prosthesis replacement., Conclusions: The extensor digitorum communis splitting approach is an effective exposure method for internal fixation or replacement in the treatment of radial head fractures., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose.

- Abstract
We present the outcomes of flexor pollicis longus tendon repairs in 34 thumbs using a six-strand M-Tang repair with venting of one or two pulleys according to site of tendon laceration. The A2 pulley was vented in all three thumbs with zone 1 injury. In 31 thumbs with zone 2 injuries, the oblique pulley was vented partially or entirely. Twenty-two thumbs had both the A1 and oblique pulleys vented. Six to 46 months post-surgery, 14 thumbs with zone 2 injuries were rated excellent, 13 good, three fair and one failure according to Tang criteria. No tendon ruptures or bowstringing occurred. Fourteen of 34 thumbs had deficits in interphalangeal joint extension averaging 13°. We conclude that venting of one or two pulleys may ensure recovery of thumb function without risking tendon bowstringing and that early active thumb motion is safe with a robust tendon repair., Level of Evidence: IV.

- Abstract
The objective of this study was to investigate the optimal developmental time to perform sex reversal in Ussuri catfish Tachysurus ussuriensis, to develop monosex breeding in aquaculture. Systematic observations of gonadal sex differentiation of P. ussiriensis were conducted. The genital ridge formed at 9 days post fertilization (dpf) and germ cells begin to proliferate at 17 dpf. The ovarian cavity began forming on 21 dpf and completed by 25 dpf while presumptive testis remained quiescent. The primary oocytes were at the chromatin nucleolus stage by 30 dpf, the peri-nucleolus stage by 44 dpf and the cortical alveoli stage by 64 dpf. The germinal vesicle migrated towards the animal pole (polarization) at 120 dpf. In presumptive testis, germ cells entered into mitosis and blood vessels appeared in the proximal gonad on 30 dpf. The efferent duct anlage appeared on 36 dpf and formation of seminal lobules with spermatogonia and lobules interstitium occurred at 120 dpf. Therefore, gonadal sex differentiation occurred earlier in females than in males, with the histological differentiation preceding cytologic differentiation in T. ussuriensis. This indicates that undifferentiated gonads directly differentiate into ovary or testis between 17 and 21 dpf and artificial induction of sexual reversal by oral steroid administration must be conducted before 17 dpf., (© 2017 The Fisheries Society of the British Isles.)

- Abstract
Objective: Bladder cancer is the most commonly malignant tumor in the urogenital tract, only next to prostate cancer with a higher incidence in China. Curcumin is the major component of curcuma longa and has multiple biological effects including anti-tumor. This study aimed to investigate the effect of curcumin on bladder cancer., Materials and Methods: SPF-grade Wistar rats were used for establishing bladder cancer model through injection of N-methyl-N-nitrosourea (MNU). Rats were then randomly divided into experimental, model and control group. 160 μmol/L curcumin were applied in the experimental group while model group received an equal volume of saline. General condition, morphology changes and cell cycle of bladder cancer cells were examined. Meanwhile, apoptotic proteins including Bcl-2, Bax and surviving were also measured by Western blot., Results: Model rats displayed fever, hematuria, decreased food and water intake, dispersed fur, lower body mass and decreased activity. Under microscopy, the bladder wall was thickened with the cauliflower-like lesion, in which significant necrotic and hemorrhagic lesions were found. Experimental group rats improved general condition without decrease of body mass. The only minor lesion was found without significant necrosis or hemorrhage without invasion into the muscular layer. The number of G1 phase cells was increased while S phase cell number was decreased after drug intervention, suggesting suppression of G1/S transition (p < 0.05). In curcumin-treated rats, the expression of Bcl-2 and Survivin were significantly decreased while Bax protein expression was significantly elevated (p < 0.05)., Conclusions: Curcumin can inhibit the growth and invasion of rat bladder cancer cells, possibly through the arresting of G1/S transition and subsequently increased apoptosis.
