Abstract
Although parasitic copepods of the genus Ergasilus von Nordmann, 1832 are globally distributed parasites of fish, their phylogenetic relationships with other Copepoda are not clear, and the characteristics of their mitochondrial genomes (mitogenomes) are not thoroughly understood. The objective of this study was to address these knowledge gaps by sequencing the complete mitogenome of Ergasilus tumidus Markevich, 1940. The complete mitogenome (GenBank Acc. No. OQ596537) was 14,431 bp long and it comprised 13 protein-coding genes (PCGs), 22 tRNAs, two tRNAs, and two control regions (CRs). Phylogenetic analyses, conducted using concatenated nucleotide and amino acid sequences of 13 protein-coding genes, produced two partially incongruent topologies. While the order Calanoida was consistently resolved as the sister lineage to the other three orders, topological instability was observed in the relationships of the orders Cyclopoida, Siphonostomatoida and Harpacticoida. Siphonostomatoida clustered with Cyclopoida in the nucleotide-based phylogeny, but with Harpacticoida in the amino acid-based phylogeny. The latter topology conforms to the widely accepted relationships, but we speculate that the former topology is more likely to be the correct one. Our study provides a complete mitogenome sequence of E. tumidus, which helps us better understand the molecular evolution of the genus Ergasilus. Additionally, we suggest a different perspective on the controversial phylogenetic relationships among Siphonostomatoida, Cyclopoida and Harpacticoida, diverging from previously accepted views.

Abstract
BACKGROUND Gyrodactylus is a lineage of monogenean flatworm ectoparasites exhibiting many features that make them a suitable model to study the host-parasite coevolutionary dynamics. Previous coevolutionary studies of this lineage mainly relied on low-power datasets (a small number of samples and a single molecular marker) and (now) outdated algorithms. METHODS To investigate the coevolutionary relationship of gyrodactylids and their fish hosts in high resolution, we used complete mitogenomes (including two newly sequenced Gyrodactylus species), a large number of species in the single-gene dataset, and four different coevolutionary algorithms. RESULTS The overall coevolutionary fit between the parasites and hosts was consistently significant. Multiple indicators confirmed that gyrodactylids are generally highly host-specific parasites, but several species could parasitize either multiple (more than 5) or phylogenetically distant fish hosts. The molecular dating results indicated that gyrodactylids tend to evolve towards high host specificity. Speciation by host switch was identified as a more important speciation mode than co-speciation. Assuming that the ancestral host belonged to Cypriniformes, we inferred four major host switch events to non-Cypriniformes hosts (mostly Salmoniformes), all of which occurred deep in the evolutionary history. Despite their relative rarity, these events had strong macroevolutionary consequences for gyrodactylid diversity. For example, in our dataset, 57.28% of all studied gyrodactylids parasitized only non-Cypriniformes hosts, which implies that the evolutionary history of more than half of all included lineages could be traced back to these major host switch events. The geographical co-occurrence of fishes and gyrodactylids determined the host use by these gyrodactylids, and geography accounted for most of the phylogenetic signal in host use. CONCLUSIONS Our findings suggest that the coevolution of Gyrodactylus flatworms and their hosts is largely driven by geography, phylogeny, and host switches.

Abstract
Influenza and coronavirus disease 2019 are independent risk factors for the development of invasive fungal disease (IFD) in critically ill patients in the intensive care unit. IFD, particularly mold infections, have a high mortality rate. The diagnosis and treatment of mold infections is challenging, and early detection and timely treatment are crucial in reducing the mortality of IFD. This review will summarize the latest epidemiology and risk factors for the development of mold infections in critically ill patients, current diagnostic criteria and challenges, as well as the treatment strategies recommended by the international clinical guidelines, aiming to provide some references for the diagnosis and treatment of mold infections in critically ill patients in clinical practice.

Abstract
Anaerobic parasitic ciliates are a specialized group of ciliates that are adapted to anoxic and oxygen-depleted habitats. Among them, Balantidium polyvacuolum, which inhabits the hindgut of Xenocyprinae fishes, has received very limited scientific attention, so the molecular mechanism of its adaptation to the digestive tract microenvironment is still unclear. In this study, transmission electron microscopy (TEM) and single-cell transcriptome analysis were used to uncover the metabolism of B. polyvacuolum. Starch granules, endosymbiotic bacteria, and multiple specialized mitochondrion-related organelles (MROs) of various shapes were observed. The MROs may have completely lost the electron transport chain (ETC) complexes I, III, IV, and V and only retained succinate dehydrogenase subunit A (SDHA) of complex II. The tricarboxylic acid (TCA) cycle was also incomplete. It can be inferred that the hypoxic intestinal environment has led to the specialization of the mitochondria in B. polyvacuolum. Moreover, carbohydrate-active enzymes (CAZymes), including carbohydrate esterases, enzymes with a carbohydrate-binding module, glycoside hydrolases, and glycosyltransferases, were identified, which may constitute evidence that B. polyvacuolum is able to digest carbohydrates and starch. These findings can improve our knowledge of the energy metabolism and adaptive mechanisms of B. polyvacuolum.

Abstract
The rapid development of big data methods and technologies has provided more and more new ideas and methods for clinical diagnosis and treatment. The emergence of large language models (LLM) has made it possible for human-computer interactive dialogues and applications in complex medical scenarios. Critical care medicine is a process of continuous dynamic targeted treatment. The huge data generated in this process needs to be integrated and optimized through models for clinical application, interaction in teaching simulation, and assistance in scientific research. Using the LLM represented by generative pre-trained transformer ChatGPT can initially realize the application in the diagnosis of severe diseases, the prediction of death risk and the management of medical records. At the same time, the time and space limitations, illusions and ethical and moral issues of ChatGPT emerged as the times require. In the future, it is undeniable that it may play a huge role in the diagnosis and treatment of critical care medicine, but the current application should be combined with more clinical knowledge reserves of critical care medicine to carefully judge its conclusions.

Abstract
Reducing the dietary CP concentration in the formulation of low-protein diets without adverse effects on animal growth performance and meat quality remains challenging. In this study, we investigated the effects of nicotinamide (NAM) on the nitrogen excretion, growth performance, and meat quality of growing-finishing pigs fed low-protein diets. To measure the nitrogen balance, we conducted two trials: in nitrogen balance trial 1, four crossbred (Duroc × Landrace × Large White) barrows (40 ± 0.5 kg BW) were used in a 4 × 4 Latin square design with four diets and periods. The diets consisted of a basal diet + 30 mg/kg NAM (a control dose), basal diet + 90 mg/kg NAM, basal diet + 210 mg/kg NAM, and basal diet + 360 mg/kg NAM. In nitrogen balance trial 2, another four barrows (40 ± 0.5 kg BW) were used in a 4 × 4 Latin square design. The diets consisted of a basal diet + including 30 mg/kg NAM (control), basal diet + 360 mg/kg NAM, low-protein diet + 30 mg/kg NAM, and low-protein diet + 360 mg/kg NAM. To measure growth performance, two trials were conducted. In growth performance trial 1, 40 barrows (37.0 ± 1.0 kg) were randomly allocated to one of four dietary treatments (n = 10 per group), whereas in growth performance trial 2, 300 barrows (41.4 ± 2.0 kg) were randomly allocated to one of four dietary treatments, with each dietary treatment conducted in five repetitions with 15 pigs each. The four diets in the two growth performance trials were similar to those in nitrogen balance trial 2. Supplementing the diet with 210 or 360 mg/kg NAM reduced urinary nitrogen excretion and total nitrogen excretion and increased nitrogen retention comparted with the control diet (P < 0.05). Compared with the control diet, the low-protein diet with 360 mg/kg NAM reduced faecal, urinary, and total nitrogen excretion (P < 0.05) without affecting nitrogen retention and average daily gain (P > 0.05). Pigs fed the low-protein diet with 360 mg/kg NAM showed a decreased intramuscular fat content in the longissimus thoracis muscle when compared with pigs fed the control diet (P > 0.05). Our results suggest NAM as a suitable dietary additive to reduce dietary CP concentration, maximise nitrogen retention and growth performance, and decrease fat deposition in pigs.

Abstract
Objective: To explore the construction of a machine learning model based on unbalanced data to predict the progression of non-nephrotic membranous nephropathy. Methods: The clinical and pathological data of patients diagnosed with non-nephrotic membranous nephropathy by renal biopsy in Shanxi People's Hospital from January 2018 to December 2021 were retrospectively analyzed.The prediction models were constructed based on logistic regression, support vector machine (SVM) and light gradient boosting machine (lightGBM), respectively. The mixed sampling technology was used to process the unbalanced data, and the area under the receiver operating characteristic curve (AUC) was used to evaluate the predictive performance of the models. Finally, Shapley additive explanation (SHAP) was used to interpret the results of the optimal prediction model. Results: A total of 148 patients were included in the study, including 84 males and 64 females, with a mean age of (47.2±12.5) years. The follow-up time [M(Q1, Q3)] was 14(7, 20) months. Twenty-three patients (15.5%) achieved the renal end-point event in the study. The SVM model had the highest AUC (0.868, 95%CI: 0.813-0.925), followed by logistic regression (AUC=0.865, 95%CI: 0.755-0.899) and lightGBM (AUC=0.791, 95%CI: 0.690-0.882). The feature recursive elimination cross validation (RFECV) method based on random forest (RF) and the SHAP plot based on the SVM model showed that immunohistochemistry IgG, total protein (TP), anti-phospholipase A2 receptor (anti-PLA2R), blood chloride and D-Dimer were risk factors affecting the progress of non-nephrotic membranous nephropathy. Moreover, patients with high immunohistochemistry IgG, anti-PLA2R and D-Dimer had an increased risk of achieving the renal end-point event. Conclusion: The SVM model established in this study can effectively predict the progress of non-nephrotic membranous nephropathy, and provide a new method for the early identification of high-risk patients and precision therapy.

Abstract
Objective: To study the incubation period of the infection with 2019-nCoV Omicron variant BA.5.1.3. Methods: Based on the epidemiological survey data of 315 COVID-19 cases and the characteristics of interval censored data structure, log-normal distribution and Gamma distribution were used to estimate the incubation. Bayes estimation was performed for the parameters of each distribution function using discrete time Markov chain Monte Carlo algorithm. Results: The mean age of the 315 COVID-19 cases was (42.01±16.54) years, and men accounted for 30.16%. A total of 156 cases with mean age of (41.65±16.32) years reported the times when symptoms occurred. The log-normal distribution and Gamma distribution indicated that the M (Q1, Q3) of the incubation period from exposure to symptom onset was 2.53 (1.86, 3.44) days and 2.64 (1.91, 3.52) days, respectively, and the M (Q1, Q3) of the incubation period from exposure to the first positive nucleic acid detection was 2.45 (1.76, 3.40) days and 2.57 (1.81, 3.52) days, respectively. Conclusions: The incubation period by Bayes estimation based on log-normal distribution and Gamma distribution, respectively, was similar to each other, and the best distribution of incubation period was Gamma distribution, the difference between the incubation period from exposure to the first positive nucleic acid detection and the incubation period from exposure to symptom onset was small. The median of incubation period of infection caused by Omicron variant BA.5.1.3 was shorter than those of previous Omicron variants.

Abstract
BACKGROUND Chilodonella uncinata is an aerobic ciliate capable of switching between being free-living and parasitic on fish fins and gills, causing tissue damage and host mortality. It is widely used as a model organism for genetic studies, but its mitochondrial metabolism has never been studied. Therefore, we aimed to describe the morphological features and metabolic characteristics of its mitochondria. METHODS Fluorescence staining and transmission electron microscopy (TEM) were used to observe the morphology of mitochondria. Single-cell transcriptome data of C. uncinata were annotated by the Clusters of Orthologous Genes (COG) database. Meanwhile, the metabolic pathways were constructed based on the transcriptomes. The phylogenetic analysis was also made based on the sequenced cytochrome c oxidase subunit 1 (COX1) gene. RESULTS Mitochondria were stained red using Mito-tracker Red staining and were stained slightly blue by DAPI dye. The cristae and double membrane structures of the mitochondria were observed by TEM. Besides, many lipid droplets were evenly distributed around the macronucleus. A total of 2594 unigenes were assigned to 23 functional classifications of COG. Mitochondrial metabolic pathways were depicted. The mitochondria contained enzymes for the complete tricarboxylic acid (TCA) cycle, fatty acid metabolism, amino acid metabolism, and cytochrome-based electron transport chain (ETC), but only partial enzymes involved in the iron-sulfur clusters (ISCs). CONCLUSIONS Our results showed that C. uncinata possess typical mitochondria. Stored lipid droplets inside mitochondria may be the energy storage of C. uncinata that helps its transmission from a free-living to a parasitic lifestyle. These findings also have improved our knowledge of the mitochondrial metabolism of C. uncinata and increased the volume of molecular data for future studies of this facultative parasite.

Abstract
Objective: To explore the reasonable time of prophylactic thyroidectomy for RET gene carriers in multiple endocrine neoplasia(MEN) 2A/2B families. Methods: From May 2015 to August 2021, RET gene carriers in MEN2A/MEN2B families were dynamically followed up at the Department of Thyroid Head and Neck Surgery, Beijing Tongren Hospital of Capital Medical University. The high-risk patients were encouraged to undergo prophylacitc total thyroidectomy according to the principle of "graded early warning system", namely the evaluation of gene detection, calcitonin value and ultrasound examination successively. Seven cases underwent the surgery, including 3 males and 4 females, aged from 7 to 29 years. According to the risk stratification listed in the guidelines of the American Thyroid Association in 2015, there were 2 cases of the highest risk, 2 cases of the high risk and 3 cases of the modest risk. Calcitonin index remained within the normal range in 3 cases and elevated in 4 cases before operation. All 7 patients underwent thyroidectomy with lymph node dissection of the level Ⅵ performed in 4 patients. Results: The time from suggestion to operation was 2 to 37 months, with an average of 15.1 months. The 6 patients were medullary thyroid carcinoma and 1 case with C-cell hyperplasia. The follow-up time was 2 to 82 months, with an average of 38.4 months. Postoperative serum calcitonin levels of all cases decreased to normal level, with biochemical cure. There was no sign of recurrence on ultrasound examination. All 7 patients had no serious complications, no obvious thyroid dysfunction. Their height, weight and other indicators of pediatric patients were similar to those of their peers, with normal growth and development. Conclusion: For healthy people with MEN2A/MEN2B family history, prophylactic thyroidectomy can be carried out selectively based on the comprehensive evaluation of "graded early warning system" with strict screening and close monitoring.

Abstract
Objective: To understand the infection status of Enterovirus (EV) in cases of acute respiratory infections (ARIs) in Luohe City, Henan Province from 2017 to 2021, and analyze the prevalence and type composition of EV in ARIs. Methods: From October 2017 to May 2021, pharyngeal swab samples were collected from 1 828 patients with ARIs in Luohe Central Hospital and the clinical epidemiological data of these cases were also collected. EV-positive samples were identified by Quantitative Real-time Polymerase Chain Reaction (qPCR). The 5'-untranslated region (5'UTR) was amplified by Reverse Transcription-Polymerase Chain Reaction (RT-PCR). The results of 5'UTR region were initially typed by Enterovirus Genotyping Tool Version 1.0. Based on the typing results, the full-length of VP1 region was amplified by RT-PCR. The EV typing was identified again by VP1 region. Results: Among 1 828 cases of ARIs, 56.7% (1 036) were males. The median (Q1, Q3) age was about 3 (1, 5) years. Patients under 5 years old accounted for 71.6% (1 309 cases). Among all cases, a total of 71 EV-positive samples were identified by qPCR, with a detection rate of 3.88% (71/1 828). The EV detection rates for men and women were 3.28% (34/1 036) and 4.67% (37/792), without statistically significant differences (χ2=2.32, P=0.14). The EV detection rates for 2 to <6 years, 6 months to <2 years, 6 to <10 years, and <6 months were 6.29% (48/763), 3.00% (18/600), 2.52% (4/159), and 1.67% (1/60) (χ2=27.91, P<0.001). The EV detection rate was 0.92% (3/326) in autumn and winter of 2017. The EV detection rates were 1.18% (6/508), 2.47% (12/485) and 8.31% (34/409) in each year from 2018 to 2020, with an increasing trend year by year(χ2trend=29.76, P<0.001). The main prevalent seasons were summer and autumn. The detection rate in spring of 2021 was 4.00% (4/100). A total of 12 types were identified and classified as CVA2, CVA4, CVA5, CVA6, CVA10, CVB3, CVB5, E5, E11, E30, PV-1, and EV-D68. The types of CVA2, CVA10, CVA6, and CVB3 were the dominant phenotypes. In 59 sample of EV typing, the main clinical manifestation was upper respiratory tract infection (36/59, 61.01%). The dominant types detected in upper respiratory tract infections were CVA10 (10/36, 27.78%), CVA6 (9/36, 25.00%) and CVB3 (8/36, 22.22%). The dominant type detected in lower respiratory tract infections was CVA2 (7/19, 36.84%). Conclusion: In Luohe City, Henan Province from 2017 to 2021, EV infection in ARIs cases has clear seasonal and age-specific patterns, and the dominant types of upper and lower respiratory tract infections are different.

Abstract
Objective: To compare the safety and efficacy of transmesenteric vein extrahepatic portosystemic shunt (TEPS) and transjugular intrahepatic portosystemic shunt (TIPS) in the treatment of cavernous transformation of the portal vein (CTPV). Methods: The clinical data of CTPV patients with patency or partial patency of the superior mesenteric vein treated with TIPS or TEPS treatment in the Department of Vascular Surgery of Henan Provincial People's Hospital from January 2019 to December 2021 were selected. The differences in baseline data, surgical success rate, complication rate, incidence rate of hepatic encephalopathy, and other related indicators between TIPS and TEPS group were statistically analyzed by independent sample t-test, Mann-Whitney U test, and Chi-square test. Kaplan-Meier survival curve was used to calculate the cumulative patency rate of the shunt and the recurrence rate of postoperative portal hypertension symptoms in both groups. Results: The surgical success rate (100% vs. 65.52%), surgical complication rate (6.67% vs. 36.84%), cumulative shunt patency rate (100% vs. 70.70%), and cumulative symptom recurrence rate (0% vs. 25.71%) of the TEPS group and TIPS group were statistically significantly different (P < 0.05). The time of establishing the shunt [28 (2141) min vs. 82 (51206) min], the number of stents used [1 (12) vs. 2 (15)], and the length of the shunt [10 (912) cm vs. 16 (1220) cm] were statistically significant between the two groups (t = -3.764, -4.059, -1.765, P < 0.05). The incidence of postoperative hepatic encephalopathy in the TEPS group and TIPS group was 6.67% and 15.79% respectively, with no statistically significant difference (Fisher's exact probability method, P = 0.613). The pressure of superior mesenteric vein decreased from (29.33 ± 1.99) mmHg to (14.60 ± 2.80) mmHg in the TEPS group and from (29.68 ± 2.31) mmHg to (15.79 ± 3.01) mmHg in TIPS group after surgery, and the difference was statistically significant (t = 16.625, 15.959, P < 0.01). Conclusion: The best indication of TEPS is in CTPV patients with patency or partial patency of the superior mesenteric vein. TEPS improves the accuracy and success rate of surgery and reduces the incidence of complications.

Abstract
Objective: To characterize the histopathological subtypes and their clinicopathological parameters of gender and onset age by common, rare and sparse primary esophageal malignant tumors (PEMT). Methods: A total of 272 437 patients with PEMT were enrolled in this study, and all of the patients were received radical surgery. The clinicopathological information of the patients was obtained from the database established by the State Key Laboratory of Esophageal Cancer Prevention & Treatment from September 1973 to December 2020, which included the clinical treatment, pathological diagnosis and follow-up information of esophagus and gastric cardia cancers. All patients were diagnosed and classified by the criteria of esophageal tumor histopathological diagnosis and classification (2019) of the World Health Organization (WHO). The esophageal tumors, which were not included in the WHO classification, were analyzed separately according to the postoperative pathological diagnosis. The χ2 test was performed by the SPSS 25.0 software on count data, and the test standard α=0.05. Results: A total of 32 histopathological types were identified in the enrolled PEMT patients, of which 10 subtypes were not included in the WHO classification. According to the frequency, PEMT were divided into common (esophageal squamous cell carcinoma, ESCC, accounting for 97.1%), rare (esophageal adenocarcinoma, EAC, accounting for 2.3%) and sparse (mainly esophageal small cell carcinoma, malignant melanoma, etc., accounting for 0.6%). All the common, rare, and sparse types occurred predominantly in male patients, and the gender difference of rare type was most significant (EAC, male∶ female, 2.67∶1), followed with common type (ESCC, male∶ female, 1.78∶1) and sparse type (male∶ female, 1.71∶1). The common type (ESCC) mainly occurred in the middle thoracic segment (65.2%), while the rare type (EAC) mainly occurred in the lower thoracic segment (56.8%). Among the sparse type, malignant melanoma and malignant fibrous histiocytoma were both predominantly located in the lower thoracic segment (51.7%, 66.7%), and the others were mainly in the middle thoracic segment. Conclusion: ESCC is the most common type among the 32 histopathological types of PEMT, followed by EAC as the rare type, and esophageal small cell carcinoma and malignant melanoma as the major sparse type, and all of which are mainly occur in male patients. The common type of ESCC mainly occur in the middle thoracic segment, while the rare type of EAC mainly in the lower thoracic segment. The mainly sparse type of malignant melanoma and malignant fibrous histiocytoma predominately occur in the lower thoracic segment, and the remaining sparse types mainly occur in the middle thoracic segment.

A shared airway during anesthesia refers to maintaining the airway and ventilation of the patient by the anesthesiologist as the surgeon performs the procedures in the same anatomic space. Due to the narrow airway space in shared airway surgery, the difficulty lies both in the exposure of surgery field and implementation of the optimized airway management strategy and maintaining the airway safety in clinical practice. In recent years, many new visualized airway management tools and supraglottic ventilation devices have been invented and verified in clinical settings. Especially, the development of tubeless supraglottic oxygenation and ventilation technique provides new insights into the airway management. This review intends to provide a reference for future innovations in airway management tools and ventilation techniques by summarizing previous airway management strategies of shared airway surgery to benefit more patients.

Abstract
BACKGROUND Management of retroperitoneal sarcoma (RPS) involving the iliac artery is challenging and requires the concerted efforts of multidisciplinary team (MDT) members during surgical treatment.
AIM To summarize the clinicopathologic features of RPS involving the iliac artery and our retroperitoneal soft tissue tumor MDT surgical experience.
METHODS In this retrospective study, 15 patients with RPS involving the iliac artery who underwent surgery at our retroperitoneal soft tissue tumor center from July 2004 to June 2020 were analyzed. Statistical analyses were performed by Student’s t-test with SPSS 16.0.
RESULTS Complete tumor resection (R0/R1) and iliac artery reconstruction were achieved in all 15 patients. All the operations were successful, with no serious complications or perioperative death. Resection with bilateral iliac artery reconstruction required a higher intraoperative blood transfusion volume than resection with unilateral iliac artery reconstruction. Recurrent cases were more likely to bleed and required a higher blood transfusion volume than primary cases. As of January 2021, 11 patients were alive, and 4 had died. Local recurrence occurred in two patients, one of whom developed liver metastasis.
CONCLUSION Resection of RPS involving iliac vessels is feasible and effective when performed by MDT members. Iliac artery oncovascular resection and reconstruction are key to a successful operation. Adequate blood preparation is important for successful completion of surgery.

Abstract
Objective: To evaluate the short- and medium-term clinical efficacy of TIPS approach combined with AngioJet thrombus aspiration technology treatment in acute portal vein thrombosis. Methods: 63 cases with acute portal vein thrombosis treated in our center from May 2017 to July 2019 were studied retrospectively, including 49 males and 14 females, aged 35-61 (46 ± 5) years. TIPS approach (with/without) combined with Angiojet thrombus aspiration and gastroesophageal varices embolization was performed simultaneously according to the patient's condition. Regular follow-up for 3-33 (22 ± 3) months after surgery was used to observe the curative effect. Results: The technical success rate was 100%. Portal vein and superior mesenteric vein blood flow were returned to normal after the operation. Two cases of biliary tract injury were untreated. Simultaneously, two cases of intrahepatic arteriovenous fistula were treated with superselective arterial embolization. During the follow-up period, 47 cases (74.61%) had complete portal vein recanalization, 13 cases (20.63%) had partial recanalization, 3 cases (4.76%) had complete portal cavernoma, 7 cases (11.11%) had symptomatic hepatic encephalopathy, 1 case had received artificial liver treatment (1.59%), 1 case had peptic ulcer (11.11%), 6 cases (9.52%) had lost to follow-up, and there was no portal hypertension-related bleeding or death. Conclusion: TIPS approach combined with AngioJet thrombus aspiration technology is safe, effective and feasible in the treatment of acute portal vein thrombosis, and the short- and medium-term clinical effects are satisfactory.

Abstract
Objectives Down syndrome critical region 1 (DSCR1) is associated with carcinogenesis and tumor growth in several types of malignancy. However, little is known about the role of DSCR1 in CRC progression. The present study aimed to elucidate the clinicopathological significance, prognostic, and function roles of DSCR1 in CRC. Methods Firstly, we analyzed DSCR1 expression in 58 paired CRC samples and Oncomine database. Then, we analyzed DSCR1 expression in two independent CRC cohorts (test cohort: n = 70; validation cohort: n = 58) and tested its overall survival (OS) by Kaplan-Meier survival analyses. Finally, we overexpressed DSCR1 in two CRC cell lines DLD1 and LoVo and analyzed its effect on cell cycle and senescence. Results DSCR1 expression was significantly decreased in CRC samples and associated with clinicopathologic features of CRC patients, such as tumor size, lymph node metastasis, and TNM stage. CRC patients with low expression of DSCR1 had shorter overall survival (OS). Kaplan-Meier survival analyses showed that the expression of DSCR1 was significant factor for OS in both cohorts. Multiple Cox regression analysis showed that DSCR1 expression was an independent prognostic marker for OS in test cohort. Overexpression of DSCR1 isoform 4 (DSCR1-4) increased p21, p16, p-NFAT1, and p-NFAT2, while decreased CDK2, CDK4, and Cyclin D1 in CRC cells. In addition, overexpression of DSCR1-4 prevented proliferation and colony formation, and induced senescence in vitro. Moreover, overexpression of DSCR1-4 inhibited tumor growth and tumor angiogenesis in vivo. Conclusions Our study found high expression of DSCR1 contributes to favorable prognosis of CRC patients and prevents cell cycle and proliferation of CRC cells, indicating a critical tumor suppressive role in CRC progression.

Abstract
Our previous studies showed that ferroptosis plays an important role in the acute and subacute stages of spinal cord injury. High intracellular iron levels and low glutathione levels make oligodendrocytes vulnerable to cell death after central nervous system trauma. In this study, we established an oligodendrocyte (OLN-93 cell line) model of ferroptosis induced by RSL-3, an inhibitor of glutathione peroxidase 4 (GPX4). RSL-3 significantly increased intracellular concentrations of reactive oxygen species and malondialdehyde. RSL-3 also inhibited the main anti-ferroptosis pathway, i.e., SLC7A11/glutathione/glutathione peroxidase 4 (xCT/GSH/GPX4), and downregulated acyl-coenzyme A synthetase long chain family member 4. Furthermore, we evaluated the ability of several compounds to rescue oligodendrocytes from ferroptosis. Liproxstatin-1 was more potent than edaravone or deferoxamine. Liproxstatin-1 not only inhibited mitochondrial lipid peroxidation, but also restored the expression of GSH, GPX4 and ferroptosis suppressor protein 1. These findings suggest that GPX4 inhibition induces ferroptosis in oligodendrocytes, and that liproxstatin-1 is a potent inhibitor of ferroptosis. Therefore, liproxstatin-1 may be a promising drug for the treatment of central nervous system diseases.

Abstract
A new species of clevelandellid ciliate, Nyctotheroides grimi n. sp., is described from the frog Fejervarya limnocharis. Light and scanning electron microscopy were used for the morphological studies, and the DNA encoding the SSU rRNA gene (SSU rDNA) and the ITS1-5.8S subunit rRNA-ITS2 region (ITS) were sequenced for genetic comparisons and phylogenetic analysis. The main distinctive morphological feature is a knob-like projection in the left-posterior end; other differential characters are the cell size, the length of the oral groove and the shape of the infundibulum. Nyctotheroides grimi possess an apical suture line in the left and right side of the anterior end and in the left side of the caudal end. In the phylogenetic analyses, the new species engroups with other Nyctotheroides species forming a monophyletic group. The high similarity in the SSU rDNA and ITS sequences between Nyctotheroides species suggests a relative recent divergence. The genetic data and the different host range support the separation of Nyctotheroides and Nyctotherus; however the morphological criterion based on the presence (in Nyctotheroides)/absence (in Nyctothterus) of an apical kinetal suture line should be modified to consider the presence of kinetal suture lines in the apical and/or the caudal left side in Nyctotheroides.

Abstract
OBJECTIVE To explore the safety, effectiveness and consistency of "Zoning Method" foraminotomy in posterior cervical endoscopic surgery. METHODS From March 2016 to October 2018, 21 patients with cervical spondylotic radiculopathy were enrolled. Endoscopic foraminotomy and nucleus pulposus enucleation were performed in the patients. There were 13 males and 8 females, aged from 35 to 56 years old with an average of (47.3±5.1) years. The surgical segment of 6 cases were C4,5, 10 cases were C5,6 and 5 cases were C6,7. The "Zoning Method" was proposed and used to complete the foraminotomy under endoscope, and then to perform nucleus pulposus removal and nerve root decompression. The operation length, intraoperative bleeding volume and complications were recorded, and NDI, VAS were evaluated before operation, 1 day after the operation and 1 week after the operation. RESULTS All the operations were successful. The operation length was(46.10±26.39) min, intraoperative bleeding volume was (50.10±18.25) ml, and there were no complications such as nerve injury, dural tear or vertebral artery injury. All 21 patients were followed up for 3 to 9 months, with a median of 6 months. Postoperative VAS and NDI were obvious improved (P<0.05);there was significant difference in VAS between postoperative 1 d and 1 week(P<0.05);and there was no significant difference in NDI between postoperative 1 d and 1 week (P>0.05). CONCLUSION Endoscopic foraminotomy with "Zoning Method" is safe clinically significant, and consistent.

Long non-coding RNA (lncRNA) small nucleolar RNA host gene 12 (SNHG12) has been identified as an oncogene in multiple cancers. However, the regulatory role of SNHG12 in BC cell progression is still obscured. The levels of SNHG12, miR-15a-5p, and Sal-like 4 (SALL4) in BC tumor tissues and cells were measured by qRT-PCR. Cell viability, apoptosis, migration, and invasion were examined by CCK8, flow cytometry, and transwell assay, respectively. The interaction between miR-15a-5p and SNHG12 or SALL4 was evaluated by dual-luciferase reporter assay. Protein expression of SALL4 was analyzed by western blot. Xenograft mice were established by subcutaneously injecting BC cells stably transfected with sh-SNHG12 and sh-NC. SNHG12 and SALL4 expressions were upregulated whereas miR-15a-5p was downregulated in BC tumors compared with normal tissues. Besides, miR-15a-5p was correlated with SNHG12 and SALL4 inversely as calculated by Pearson's correlation coefficient. More importantly, SNHG12 knockdown attenuated BC tumor growth in vitro and in vivo. Subsequently, dual-luciferase reporter assay confirmed the interaction between miR-15a-5p and SNHG12 or SALL4. The rescue experiments revealed that miR-15a-5p inhibitor restored SNHG12 silencing induced inhibition on BC cell proliferation, migration, invasion, and promotion of apoptosis. Additionally, SNHG12 was found to accelerate BC cell progression by absorbing miR-15a-5p to enhance SALL4 expression. SNHG12 promotes cell proliferation, migration, and invasion but suppresses apoptosis in BC by upregulating SALL4 expression via sponging miR-15a-5p, representing potential targets for the development of novel diagnosis and treatment methods.

Abstract
Objective: To evaluate the cardiac functional changes in hypertrophic cardiomyopathy(HCM) patients with β-myosin heavy chain gene (MYH7) mutations by three-dimensional (3D) speckle tracking imaging(3D-STI) and conventional echocardiography modalities, and then to explore the potential predictors of adverse cardiovascular events in these patients. Methods: A consecutive series of 192 HCM patients admitted in our center from October 2014 to October 2016 were genetically screened to identify MYH7 mutations in this retrospective study. A total of 43 HCM patients with MYH7 mutations were enrolled. The patients were divided into events group(n=13) and no event group(n=30) according to the presence or absence of adverse cardiovascular events(primary and secondary endpoints). All patients were followed up to January 2019 after comprehensive evaluation of 3D-STI, two-dimensional and Doppler echocardiography. The adverse cardiovascular events were recorded. Results: The median follow up time was 1 012 (812, 1 330) days. During follow-up, 13 patients (30.2%) reached endpoints: 6 cases of the primary endpoints(2 cases of sudden cardiac death(SCD), 3 cases of survival after defibrillation, and 1 case of appropriate implantable cardioverter-defibrillator(ICD) discharge); 7 cases of the second endpoints(5 cases of heart failure hospitalization, 1 case of syncope and cardioversion due to supraventricular tachycardia, and 1 case of end-stage HCM). Patients with adverse cardiovascular events had higher prevalence of syncope and risk of SCD, enlarged left atrial volume index(LAVI) and reduced 3D left ventricular global longitudinal train (3D-GLS), as compared to those without adverse events(all P<0.05). The multivariate Cox regression analysis showed that reduced 3D-GLS(HR=0.814, 95%CI 0.663-0.999, P=0.049) was an independent predictor for adverse cardiovascular events. The cutoff value of 3D-GLS≤13.67% was linked with significantly increased risk of adverse cardiovascular events in this patient cohort(AUC=0.753, 95%CI 0.558-0.948, sensitivity 86%, specificity 69%, P<0.05). The Kaplan-Meier analysis indicated that the patients with the 3D-GLS≤ 13.67% faced higher risk of death than those with 3D-GLS>13.67%. Conclusion: 3D-GLS is useful on predicting adverse cardiovascular events in HCM patients with MYH7 mutations.

Abstract
Objective: To identify problems and demands for antenatal care (ANC) among pregnant women in different trimesters of pregnancy in Shanghai for optimizing ANC service during the epidemic of COVID-19. Method: s Organized by maternal and child health care institute in the 16 districts of Shanghai, a cross sectional study was conducted among pregnant women who came to pregnancy registration in the community health centers or attended ANC in midwifery hospitals from February 7 to February 12, 2020. Consented participating women completed a semi-structured online questionnaire voluntarily. Data was analyzed using frequency,chi-square test and scoring. Result: s A total of 2 002 valid questionnaires were collected from 183 community health centers and 67 midwifery hospitals. About 94.6%(1 894/2 002) of the pregnant women worried about being infected during the COVID-19 epidemic, and 14.7% (294/2 002) demanded for psychological consultation. Time-lapse appointments for ANC were requested by 87.7% (1 756/2 002) of the participants for avoiding presenting themselves in people-density places. Compared with other pregnancy trimesters, pregnant women in the second trimester were more willing to reduce the frequency of ANC (35.2% versus 39.5% versus 48.1%, P<0.01). Compared with multiparas, primiparas were more willing to have online consultation and guidance (49.2% versus 63.8%, P<0.01). Regarding the needs for health knowledge on COVID-19, personal protection against 2019 novel coronavirus (2019-nCoV) was the most concerned for pregnant women, and 71.0% (1 421/2 002) of them preferred to obtain knowledge through health applications, official Weibo and WeChat. Conclusions: Pregnant women in Shanghai critically concern about the risk of 2019-nCoV infections, and highly demand knowledge and measures on prevention and protection from COVID-19. They ask for having time-lapse appointments for ANC and online access to health information and services. Maternal and child care institutes should understand the demands of pregnant women, optimize the means of ANC service, and provide tailored and accessible health education and service for the safety of mother and child.

Abstract
The majority strand of mitochondrial genomes of crustaceans usually exhibits negative GC skews. Most isopods exhibit an inversed strand asymmetry, believed to be a consequence of an inversion of the replication origin (ROI). Recently, we proposed that an additional ROI event in the common ancestor of Cymothoidae and Corallanidae families resulted in a double-inverted skew (negative GC), and that taxa with homoplastic skews cluster together in phylogenetic analyses (long-branch attraction, LBA). Herein, we further explore these hypotheses, for which we sequenced the mitogenome of Asotana magnifica (Cymothoidae), and tested whether our conclusions were biased by poor taxon sampling and inclusion of outgroups. (1) The new mitogenome also exhibits a double-inverted skew, which supports the hypothesis of an additional ROI event in the common ancestor of Cymothoidae and Corallanidae families. (2) It exhibits a unique gene order, which corroborates that isopods possess exceptionally destabilized mitogenomic architecture. (3) Improved taxonomic sampling failed to resolve skew-driven phylogenetic artefacts. (4) The use of a single outgroup exacerbated the LBA, whereas both the use of a large number of outgroups and complete exclusion of outgroups ameliorated it.

Abstract
Interferon regulatory factors (IRFs) are a family of transcription factors essential to the control of antiviral immune response, cell growth, differentiation and apoptosis. IRF10 was originally found in chicken, which was induced by the v-Rel oncoprotein in lymphoid cell lines and involved in the upregulation of major histocompatibility complex (MHC) class I and guanylate-binding protein. In fish, IRF10 plays negative roles in regulation of the interferon (IFN) response. Here, we identified a splice variant of IRF10, named as EcIRF10-SF in orange spotted grouper, which shares the first three exons with the long form (EcIRF10-LF) and retains part of intron 3, creating a premature termination codon. Furthermore, we observed that the EcIRF10-SF exhibits similar expression pattern compared to its native counterparts. Functional studies demonstrate that the two EcIRF10 isoforms repress DrIFNϕ1 and DrIFNϕ3 promoter activity and negatively regulate fish antiviral gene expression. Subcellular localization analysis shows that the amino acids from 57 to 86 within DBD are required for IRF10 nuclear import. Overall, our description of transcript diversification of IRF10 in the grouper provides a coherent framework to further dissect its roles in immune response.

Abstract
The iron chelator deferoxamine has been shown to inhibit ferroptosis in spinal cord injury. However, it is unclear whether deferoxamine directly protects neurons from ferroptotic cell death. By comparing the survival rate and morphology of primary neurons and SH-SY5Y cells exposed to erastin, it was found that these cell types respond differentially to the duration and concentration of erastin treatment. Therefore, we studied the mechanisms of ferroptosis using primary cortical neurons from E16 mouse embryos. After treatment with 50 μM erastin for 48 hours, reactive oxygen species levels increased, and the expression of the cystine/glutamate antiporter system light chain and glutathione peroxidase 4 decreased. Pretreatment with deferoxamine for 12 hours inhibited these changes, reduced cell death, and ameliorated cellular morphology. Pretreatment with the apoptosis inhibitor Z-DEVD-FMK or the necroptosis inhibitor necrostain-1 for 12 hours did not protect against erastin-induced ferroptosis. Only deferoxamine protected the primary cortical neurons from ferroptosis induced by erastin, confirming the specificity of the in vitro ferroptosis model. This study was approved by the Animal Ethics Committee at the Institute of Radiation Medicine of the Chinese Academy of Medical Sciences, China (approval No. DWLL-20180913) on September 13, 2018.

Abstract
OBJECTIVE To compare the effects of thoracic epidural administration of lidocaine on hemodynamic and arousal responses of double lumen tracheal intubation during induction of anesthesia. METHODS In the study, 40 patients with American Society of Anesthesiologists (ASA) physical statuses I-II, aged 19-66 years, scheduled for elective thoracic surgeries under general anesthesia requiring orotracheal intubation were allocated to either the double-lumen endobronchial intubation (T group) or double-lumen endobronchial intubation after epidural administration of lidocaine (E group). After an intravenous anesthetic induction, the orotracheal double-lumen intubation was performed using a Macintosh direct laryngoscopy (MDLS), respectively. Invasive blood pressure (BP), heart rate (HR) and bispectral index (BIS) were recorded before and after anesthetic induction, immediately after intubation and 5 minutes after intubation with 1-minute interval and the intubation time also noted. The rate pressure product (RPP) was calculated. RESULTS After anesthetic induction, BP and RPP in the two groups decreased significantly compared with their preinduction values. In comparison with their postinduction values, the orotracheal intubation in the two groups caused significant increases in BPs, HRs and RPP. In comparison with their preinduction values, BPs decreased significantly in E group, systolic blood pressure (SBP), diastolic blood pressure (DBP) and mean arterial pressure (MAP) increased significantly and lasted for 1 min in T group. The HRs of both groups after intubation were significantly higher than their baseline values , and increased in HR and lasted for 1 min and 4 min in E group and T group, respectively. SBP, DBP, MAP, HR and RPP after intubation in T group were significantly higher than those of E group during the observation period. The values of BIS were similar between both the groups. In T group, the incidences of SBP percent increased>30% of the baseline value and RPP more than 22 000 were significantly higher than in E group. None of the patients in group E had SBP more than 130% of the baseline value and RPP more than 22 000. CONCLUSION During double-lumen endobronchial intubation, epidural administration of lidocaine can provide less hemodynamic response and similar arousal response.

Abstract
Objective: To investigate the incidence of asymptomatic sinusitis in children by magnetic resonance imaging. Method: Collected the head MRI of 1-12 years old children. According to the examination site,the MRI group and the pituitary MRI group (both sinus level) were included.The nasal-sinusitis-like changes in the field were used as positive criteria. Statistical analysis was conducted on the test results. Result: In 3 900 children with MRI, the positive rate of sinusitis was 30.21%. The positive rate increased from 2 years old to 3 years old and remained at the age of 11 years.The higher positive rate was slightly decreased at 12 years old; 1 228 cases of pituitary MRI examination, the positive rate of nasal-sinusitis was 38.27%, the positive rate increased significantly from the age of 2, reached the peak at 6 years old, and then fell back, still kept high positive rate, the lowest to 12 years old. The positive rate of total sinusitis was 32.14%. No obvious difference was found between two groups. Conclusion: Children's skull and pituitary MRI imaging suggests that the positive rate of nasal-innocuous sinusitis is related to age, peaking at 3 to 8 years old, and then gradually decreasing.

Abstract
Chronic liver disease has caused increasing numbers of deaths worldwide. Fatty liver hemorrhagic syndrome, one of the chronic liver diseases in laying hens, has great similarity to non-alcoholic fatty liver disease (NAFLD) in humans. It is characterized by the pathological accumulation of liver fat. Non-invasive techniques are needed for early identification of fibrosis. As primary de novo lipogenesis in the liver of chicken is similar to that of humans, mature chicken is an ideal animal model for the understanding of NAFLD. This study was aimed to evaluate the relationships between gut microbiota and natural chronic liver disease (i.e., non-alcoholic steatohepatitis [NASH] and fibrosis stages) in a well-characterized laying hen population. One hundred 20-wk-old Hy-Line Brown laying hens were used and fed with basal diets until 52 wk of age. At the end of the experiment, birds were killed for sampling blood, liver, and cecal contents, and then classified by liver histology measurement into different groups. We investigated microbial community structure of cecum using 16S rRNA gene sequencing. Subjects in stage 0 fibrosis without NASH were classified as low NAFLD (Group A), subjects in stage 1-2 fibrosis with mild to moderate NASH were defined as low NASH (Group B), and subjects in stage 3 fibrosis were defined as severe NASH (Group C). The abundance of Firmicutes was reduced in Groups B and C (P < 0.001), whereas opposite results were observed for the abundance of Bacteroidetes. Additionally, the families Bacteroidaceae, Ruminococcaceae Lachnospiraceae, and lactobacillae were significantly different between groups of differing fibrosis stages (P < 0.001), driven entirely by alterations of Bacteroides and lactobacillus and lachnospiraceae genera (P < 0.001), were observed. Results indicated that cecal dysbiosis was linked with the severity of fibrosis and NASH; importantly, increased levels of serum AST, alkaline phosphatase, and uric acid were accompanied with liver fibrosis and NASH severity. Collectively, these data highlight the role of gut-liver axis and associations between the gut microbiota and fibrosis and NASH severity.

Abstract
The phylogeny of Isopoda, a speciose order of crustaceans, remains unresolved, with different data sets (morphological, nuclear, mitochondrial) often producing starkly incongruent phylogenetic hypotheses. We hypothesized that extreme diversity in their life histories might be causing compositional heterogeneity/heterotachy in their mitochondrial genomes, and compromising the phylogenetic reconstruction. We tested the effects of different data sets (mitochondrial, nuclear, nucleotides, amino acids, concatenated genes, individual genes, gene orders), phylogenetic algorithms (assuming data homogeneity, heterogeneity, and heterotachy), and partitioning; and found that almost all of them produced unique topologies. As we also found that mitogenomes of Asellota and two Cymothoida families (Cymothoidae and Corallanidae) possess inversed base (GC) skew patterns in comparison to other isopods, we concluded that inverted skews cause long-branch attraction phylogenetic artifacts between these taxa. These asymmetrical skews are most likely driven by multiple independent inversions of origin of replication (i.e., nonadaptive mutational pressures). Although the PhyloBayes CAT-GTR algorithm managed to attenuate some of these artifacts (and outperform partitioning), mitochondrial data have limited applicability for reconstructing the phylogeny of Isopoda. Regardless of this, our analyses allowed us to propose solutions to some unresolved phylogenetic debates, and support Asellota are the most likely candidate for the basal isopod branch. As our findings show that architectural rearrangements might produce major compositional biases even on relatively short evolutionary timescales, the implications are that proving the suitability of data via composition skew analyses should be a prerequisite for every study that aims to use mitochondrial data for phylogenetic reconstruction, even among closely related taxa.

Abstract
Objective: To determine whether asthma has a different metabolic glycerophospholipid profile in serum between women and men with asthma. Methods: Fifty-one outpatients with asthma (17 men, 34 women) were enrolled from Peking University Third Hospital from Jan 2015 to Dec 2015. Clinical data such as gender, age, body mass index, pulmonary function were recorded. Glycerophospholipid profile were measured in serum using liquid chromatography-mass spectrometry (LC-MS)-based metabolomics analysis. Projections to latent structures-discriminate analysis (PLS-DA) was used to compare the differences of glycerophospholipid level between men and women. Receiver Operating Characteristic (ROC) Curve was established from men and women. Results: Significantly different glycerophospholipid level were confirmed quantitatively between women and men. Levels of phosphatidylethanolamine (PE), phosphatidylcholine acetal phospholipid (PCP), lysophosphatidyl ethanolamine (LPE), alkyl phosphatidylethanolamine [PE(O)] were significantly higher in women relative to men [PE36: 2, PCP32: 1, LPE18: 0, and PE(O40: 7) was 0.050 (0.037, 0.079) vs 0.043 (0.000, 0.071), 0.057 (0.035, 0.727) vs 0.034 (0.000, 0.057), 0.233 (0.129, 0.390) vs 0.126 (0.075, 0.212), 0.007(0.000, 0.041) vs 0.000 (0.000, 0.000), respectively, all P<0.05). Levels of lysophosphatidylcholine (LPC), lysophosphatidylserine (LPS), and lysophosphatidylphosphatidylcholine [LPC(O)] were significantly lower in women compared to men [Levels of LPS22: 6, LPS20: 4, and LPS18: 1 were 0.000(0.000, 0.003) vs 0.009(0.000, 0.012), 0.015(0.010, 0.026) vs 0.047(0.022, 0.081), 0.008(0.003, 0.179) vs 0.020(0.008, 0.040), respectively, all P<0.05]. Area Under ROC Curve (AUC) of LPS (LPS20: 4) was 0.814. Conclusions: Glycerophospholipid levels in serum are significantly different between women and men asthmatic patients. LPS may contribute to gender based differences in asthmatics.

Abstract
Ferroptosis is an iron-dependent novel cell death pathway. Deferoxamine, a ferroptosis inhibitor, has been reported to promote spinal cord injury repair. It has yet to be clarified whether ferroptosis inhibition represents the mechanism of action of Deferoxamine on spinal cord injury recovery. A rat model of Deferoxamine at thoracic 10 segment was established using a modified Allen's method. Ninety 8-week-old female Wistar rats were used. Rats in the Deferoxamine group were intraperitoneally injected with 100 mg/kg Deferoxamine 30 minutes before injury. Simultaneously, the Sham and Deferoxamine groups served as controls. Drug administration was conducted for 7 consecutive days. The results were as follows: (1) Electron microscopy revealed shrunken mitochondria in the spinal cord injury group. (2) The Basso, Beattie and Bresnahan locomotor rating score showed that recovery of the hindlimb was remarkably better in the Deferoxamine group than in the spinal cord injury group. (3) The iron concentration was lower in the Deferoxamine group than in the spinal cord injury group after injury. (4) Western blot assay revealed that, compared with the spinal cord injury group, GPX4, xCT, and glutathione expression was markedly increased in the Deferoxamine group. (5) Real-time polymerase chain reaction revealed that, compared with the Deferoxamine group, mRNA levels of ferroptosis-related genes Acyl-CoA synthetase family member 2 (ACSF2) and iron-responsive element-binding protein 2 (IREB2) were up-regulated in the Deferoxamine group. (6) Deferoxamine increased survival of neurons and inhibited gliosis. These findings confirm that Deferoxamine can repair spinal cord injury by inhibiting ferroptosis. Targeting ferroptosis is therefore a promising therapeutic approach for spinal cord injury.

Abstract
The role of Grb2-associated binder 1 (Gab1) in bFGF-activated PI3K-AKT pathway of endothelial cells remains largely unknown. To elucidate this role, a set of studies with siRNA knockdown of Gab1 was performed. Knockdown of Gab1 using siRNA was performed in fused endothelial cell line EA.hy926 and the low level of Gab1 was confirmed with quantitative R-T PCR and Western blotting. Effects of Gab1 down-regulation were examined on several aspects: bFGF-induced AKT phosphorylation, proliferation, migration and vessel tubing formation of EA.hy926 cells. The bFGF-induced AKT phosphorylation of wild-type EA.hy926 cells was both dose-dependent and time dependent with a peak at 10 ng/ml and about 30 min after bFGF treatment. The AKT activation was significantly reduced in Gab1 siRNA-treated EA.hy926 cells. The blocking of Gab1-AKT path resulted in a set of biological alterations of EA.hy926 cells: (i) reduced proliferation; (ii) impaired migration; (iii) decreased vessel tubing formation in both 2D and 3D culture. All data support that Gab1 is associated with angiogenesis function of EA.hy926 endothelium cells via PI3K-Akt signaling pathway.

Abstract
The genus Chilodonella includes free-living ciliated protozoa as well as pathogenic species for freshwater fish, with Chilodonella hexasticha and Chilodonella piscicola being the most important ones. These parasites cause outbreaks with high mortalities among farmed freshwater fishes with great economic losses. There are few reports of these species in China, and their identification has been based mostly on their morphological characteristics. In the present work, the parasites causing five outbreaks occurring in China between 2014 and 2017 have been identified by morphological and genetic analysis. We provide the first records of Ctenopharingodon idella and Siniperca chuatsi as hosts of C. hexasticha, and of Procypris rabaudi and Schizothorax wangchiachii as hosts of C. piscicola. There are no differences in the gross pathological findings produced by C. hexasticha and C. piscicola, consisting in desquamation and necrosis of epithelial cells in the skin and gills and in severe fusion of gill lamellae. However, both species differ in their geographic distribution: C. piscicola was found in farms located at altitudes over 1500 m above sea level and with a water temperature ≤18 °C, while C. hexasticha was found in farms located at altitudes under 50 m above sea level and with a water temperature ≥21 °C. Present results confirm that C. hexasticha and C. piscicola are two different species that can be differenced by their morphology; however, their biological variability may lead to erroneous identifications and the diagnosis should be preferably based in genetic analysis including nuclear LSU rDNA and mitochondrial SSU rDNA sequences.

Abstract
The ban on the use of antibiotic feed additives as growth promoters compelled the researchers for exploring the future utility of other alternatives. This experiment was designed to evaluate the effect of acidified drinking water on growth performance, gastrointestinal pH, digestive enzymes, intestinal histomorphology, and cecum microbial counting of the broiler chicken. A total of 540 one-day-old male broilers (Arbor Acre) were randomly assigned to 5 treatments, with 6 replicates of 18 chicks per replicate. Broilers received diets and water as follows: NC (negative control, basal diet, normal water), PC (positive control, basal diet + 8 ppm colistin sulfate + 8 ppm enduracidin, normal water), A1 (basal diet, continuous supply of acidified water during whole experiment period), A2 (basal diet, intermittent acidification of water during 0 to 14 d, 22 to 28 d, and 36 to 42 d), and A3 [basal diet, intermittent acidification of water (24 h/d from 0 to 14 d and from 10:00 am to 4:00 pm on d 15 to 42)]. During the entire period, the acidified groups (A1, A2, and A3) and PC group showed improve on weight gain, average daily gain and feed conversion ratio compared to NC group (P < 0.05). The pH in crop, proventriculus and ileum at 43 d declined by 0.04, 1.03, 1.23; 0.55, 0.69, 0.70; and 0.63, 0.74, 1.21 in A1, A2, and A3 group, respectively. There was a significant decline of lipase activity in the PC and acidified groups compared to NC group. The A2 group had higher villus height in jejunum than NC group. The PC and acidified groups reduced (P < 0.05) the total aerobic bacteria count of cecum when contrasted to NC group. Therefore, we conclude that acidified drinking water can improve growth performance, compensate for gastric acidity, and control pathogenic bacteria in broilers and may be considered as a potential alternative to improve production parameters. Discontinuous supply of acidified water had the same or even better influence on broilers compared to continuous supply.

Abstract
Lipid metabolism can influence host’s health. There is increasing evidence for interplay between two key regulating factors in lipid metabolism: bile acids (BAs) and gut microbiota. However, very little is known about how types of different diet-supplemented bile salts (BS) influence this interaction in vivo. We sought to explore these relationships using grass carp (Ctenopharyngodon idellus), which often suffers functional disorder of liver and gallbladder. We studied fluctuations of BAs in the gall and changes of microbial communities in the gut in response to seven different diets: five different BS, chelating BS agent, and control. The BS comprised two primary BS [sodium taurochololate (TCAS) and sodium taurochenodeoxycholate (TCDCAS)], sodium tauroursodeoxycholate (TUDCAS), and two secondary BS [sodium taurodeoxycholate (TDCAS) and sodium taurolithocholate (TLCAS)]. Supplementation of primary BS caused a more significant fluctuation of biliary BAs than secondary BS, and TCAS caused a more prominent increase than TCDCAS and TUDCAS. For the gut microbiota, primary BS tended to increase their diversity and induce community succession, secondary BS resulted in a higher firmicutes/bacteroidetes ratio, while TUDCAS had no significant effects. Changes of the gut microbiota triggered by different types of BS caused alteration in BAs biotransformation. Two-obesity-associated families, Lachnospiraceae and Ruminococcaceae were positively correlated with biliary cholic acid (CA), taurochenodeoxycholic acid (TCDCA), and deoxycholic acid (DCA). As both primary and secondary BS resulted in increased synthesis of toxic secondary Bas by the gut microbiota, future studies should pay closer attention to gut microbiota when considering BA treatment.

Abstract
Parabreviscolexniepini is a recently described caryophyllidean monozoic tapeworm from schizothoracine fish on the Tibetan Plateau. In the present study, the complete mitochondrial genome of P.niepini is determined for the first time. The mitogenome is 15,034 bp in length with an A+T content of 59.6%, and consists of 12 protein-encoding genes, 22 tRNA genes, two rRNA genes, and two non-coding regions. The secondary structure of tRNAs exhibit the conventional cloverleaf structure, except for trnS1(AGN) and trnR, which lack DHU arms. The anti-codon of trnS1(AGN) in the mitogenome of P.niepini is TCT. The two major non-coding regions, 567 bp and 1428 bp in size, are located between trnL2 and cox2, trnG and cox3, respectively. The gene order of P.niepini shows a consistent pattern with other caryophyllideans. Phylogenetic analysis based on mitogenomic data indicates that P.niepini has a close evolutionary relationship with tapeworms Breviscolexorientalis and Atractolytocestushuronensis.

Abstract
As a result of great diversity in life histories and a large number of described species, taxonomic and phylogenetic uncertainty permeates the entire crustacean order of Isopoda. Large molecular datasets capable of providing sufficiently high phylogenetic resolution, such as mitochondrial genomes (mitogenomes), are needed to infer their evolutionary history with confidence, but isopod mitogenomes remain remarkably poorly represented in public databases. We sequenced the complete mitogenome of Cymothoa indica, a species belonging to a family from which no mitochondrial genome was sequenced yet, Cymothoidae. The mitogenome (circular, 14484 bp, A+T = 63.8%) is highly compact, appears to be missing two tRNA genes (trnI and trnE), and exhibits a unique gene order with a large number of rearrangements. High compactness and the existence of palindromes indicate that the mechanism behind these rearrangements might be associated with linearization events in its evolutionary history, similar to those proposed for isopods from the Armadillidium genus (Oniscidea). Isopods might present an important model system to study the proposed discontinuity in the dynamics of mitochondrial genomic architecture evolution. Phylogenetic analyses (Bayesian Inference and Maximum Likelihood) conducted using nucleotide sequences of all mitochondrial genes resolved Oniscidea and Cymothoida suborders as paraphyletic. Cymothoa indica was resolved as a sister group (basal) to all remaining isopods, which challenges the accepted isopod phylogeny, where Cymothoida are the most derived, and Phreatoicidea the most basal isopod group. There is growing evidence that Cymothoida suborder might be split into two evolutionary distant clades, with parasitic species being the most basal split in the Isopoda clade, but a much larger amount of molecular resources carrying a high phylogenetic resolution will be needed to infer the remarkably complex evolutionary history of this group of animals with confidence.

Abstract
Gut microbiota plays a crucial importance in their host. Disturbance of the microbial structure and function is known to be associated with inflammatory intestinal disorders. Enteritis is a significant cause of high mortality in fish species, including grass carp (Ctenopharyngodon idellus). Study regarding the association between microbial alternations and enteritis in grass carp is still absent. In this study, changes in the gut microbiota of grass carp suffering from enteritis were investigated using NGS-based 16S rRNA sequencing. Six healthy and ten abnormal fish (showing reddening anus, red odiferous fluid accumulating in the abdominal capacity, and flatulence and haemorrhage in the intestine) were collected from a fish farm in Huanggang Fisheries Institute (Hubei, China). Our results revealed that the diversity, structure, and function of gut microbiota were significantly different between diseased and healthy fish (P < 0.05). Particularly, members of the genera Dechloromonas, Methylocaldum, Planctomyces, Rhodobacter, Caulobacter, Flavobacterium, and Pseudomonas were significantly increased in diseased fish compared with that in healthy fish (P < 0.05). Predicted function indicated that microbiota significantly changed the specific metabolic pathways (related to amino acid metabolism, xenobiotics biodegradation and metabolism, and carbohydrate metabolism) in diseased fish (P < 0.05). Taken together, our findings point out the association between changes of the gut microbiota and enteritis in grass carp, which provide basic information useful for diagnoses, prevention, and treatment of intestinal diseases occurring in cultured fish.

Abstract
This study compared the effects of sodium selenite and selenium yeast and their combination on laying performance, egg quality, antioxidant capacity, and selenium (Se) contents in tissues and eggs. Two-hundred-eighty-eight Jing Hong layers that were similar in laying rate (87.5 ± 0.38%) and body weight (1.70 ± 0.02 kg) were randomly distributed into 4 treatments for 11 wk (from 203 d old to 279 d old) with 9 replicates of 8 hens per replicate. The diets (corn-soybean meal diet) were supplemented with 0 [blank control (BC)], 0.3 mg/kg Se from sodium selenite (SS), 0.15 mg/kg Se from sodium selenite and 0.15 mg/kg Se from Se yeast (SS+SY), or 0.3 mg/kg Se from Se yeast (SY). Results showed that the laying rate of the SS+SY group increased significantly (P < 0.05) compared to the BC and SY groups. There were no differences (P > 0.05) in egg quality between the Se-supplemented diets and the BC diet. The serum glutathione peroxidase (GSH-Px) activity was increased (P < 0.01) in hens fed Se-supplemented diets compared to the BC diet. The liver superoxide dismutase (SOD) activity of the SY group was increased significantly (P < 0.05) compared to the BC group. Significant increase (P < 0.01) due to SY supplementation was noted in the serum vitamin E content compared to BC and SS. Layers fed Se-supplemented diets had higher (P < 0.01) contents of Se in the serum, liver, and kidney compared to the BC diet. Compared to BC, Se content in eggs was significantly increased (P < 0.05) by feeding supplementary Se. In conclusion, the effects of SS and Se yeast were approximately equal in promoting antioxidant capacity of laying hens, while Se yeast is easier to deposit into eggs and tissues. The diet with added equal amounts of the 2 sources of Se was more cost effective and affordable than a comparable amount of Se yeast to obtain the promising production performance and nearly similar Se deposition.

Abstract
Objective: Investigate the effects of inducible ppp2r1a knockout on main physiological function in adult mice and study the mechanism. Methods: Ppp2r1a(flox/flox) mice and CAGG-CreER mice were hybridized to obtain 20 CAGG-CreER ppp2r1a(flox/flox) and 20 mice in homozygous group. Two groups of mice were divided into 4 groups respectively, finally we got 8 groups with 5 mice in each group. Tamoxifen was injected intraperitoneally to acquire inducible ppp2r1a knockout mice. The knockout efficiency of PP2A Aα in vital organs was measured by Western blot. At 0, 2, 4 and 6 days after injection, we measured body weight, histopathological change, peripheral blood cell counts and blood biochemical. Real-time PCR was performed to measure expression of liver glucolipid metabolism genes. Results: After tamoxifen injection for 6 days, the knockout efficiency of PP2A Aα in vital organs was 35%, 12%, 15%, 60%, 69% and 72%, respectively in heart, liver, spleen, lung, kidney and brain. After tamoxifen injection for 6 days, the weight of homozygous mice was lower than that of wild type mice, with values of (17.42±1.76) g and (21.69±1.82) g, respectively (P<0.05). Moreover, the activity level, abdominal and renal fat were significantly decreased in homozygous mice. Homozygous mice survived no more than 7 days. Compared with wild type mice, the organ coefficient of spleen of homozygous mice was decreased at the 6th day, with values of (0.59±0.10)% and (0.36±0.05)% respectively (P<0.05). Obvious spleen atrophy and marked decrease of nucleated cells were showed by performing HE staining. Tunel staining revealed increased apoptosis ratio of splenic lymphocytes in homozygous mice. The levels of alanine aminotransferase (ALT) and aspartate transaminase (AST) of homozygous mice were higher than wild type mice (P<0.05). The values of ALT and AST in homozygous mice were (153.68±62.80) U/L and (193.2±44.28) U/L. The corresponding values in wild type mice were (41.02±12.91) U/L and (69.40±9.55) U/L. The above results indicated that ppp2r1a knockout caused liver damage. Blood sugar level of homozygous mice was lower than in wild type mice (P<0.05), with values of (4.20±1.99) mmol/L and (8.88±0.65) mmol/L respectively. Plasma total cholesterol (TC), high density lipoprotein (HDL) and β-hydroxybutyric acid (β-HB) level of homozygous mice were higher than those of wild type mice (P<0.05). The values of TC, HDL and β-HB in homozygous mice were (3.12±0.39), (1.53±0.38) and (2.49±0.89) mmol/L. The corresponding values in wild type mice were (1.69±0.92), (0.78±0.50) and (0.45±0.30) mmol/L respectively. The above results indicated that ppp2r1a loss interfered glucose and cholesterol metabolism. In addition, we also found that the white blood cell count (WBC) and lymphocyte count (LYM) of homozygous mice were lower than in wild type mice (P<0.05). The values of WBC and LYM in homozygous mice were (1.88±0.89)×10(9)/L and (0.92±0.37)×10(9)/L respectively. The corresponding values in wild type mice were (3.91±0.80)×10(9)/L and (2.74±0.52)×10(9)/L respectively. The mRNA levels of glucose-6-phosphatase (G6P) and phosphoenolpyruvate carboxykinase (PEPCK) of homozygous were lower than wild type mice (P<0.05). The fold change of G6P and PEPCK in homozygous mice was 0.46±0.11 and 0.72±0.07 respectively. The corresponding fold change in wild type mice was 1.02±0.07 and 1.02±0.06 respectively. Conclusion: Whole body ppp2r1a is essential for the survival of adult mice, due to the important role in maintaining the metabolism of glucose and cholesterol of liver.

Abstract
Over supplementation of copper (Cu) in animal diets may cause serious pollution in soil, water and harvested crops. To minimize the potential pollution, the effects of corn-soybean basal diet with or without supplementation of 8 mg Cu/kg on laying performance, plasma biochemical metabolic indices, and antioxidant status in laying hens were evaluated under normal and cyclic high temperatures. A total of 240 Hy-Line Brown laying hens were randomly allotted to 4 treatments with 6 replicates of 10 hens per replicate according to factorial design involved in 2 temperatures [normal temperature (NT) vs. cyclic high temperature (CHT)] and 2 dietary Cu addition amount [Cu0 (0 mg/kg) vs. Cu8 (8 mg/kg in the form of CuSO4·5H2O)]. The experimental period included 1-week adaptation, 2-week heat stress and 2-week convalescence. The temperatures of NT groups in the same period or any groups during other periods were kept at 26 ± 2°C except that of CHT groups were 26 ± 2°C∼33 ± 2°C cyclically during heat stress period. CHT groups increased (P < 0.05) the rectal temperature and plasma glucose content under heat stress, but decreased (P < 0.01) the egg yield at the second week of heat stress and the first week of convalescence, and the plasma triglyceride, uric acid, and triiodothyronine levels under heat stress. Cu8 groups increased (P < 0.05) egg weight at the first week of convalescence, and plasma thyroxin level during the whole convalescence. Interactions between temperature and Cu content existed (P < 0.05) in the laying rate at the first week of convalescence, and the plasma lactic dehydrogenase level under heat stress. Conclusively, the CHT impaired laying performance. The Cu content (10.3 mg/kg) in corn-soybean basal diet might be sufficient for meeting the maintenance and production requirements of late-phase laying hens, and no Cu supplementation had no adverse effects on egg production and antioxidant indices under cyclic high (26 ± 2°C∼33 ± 2°C) or normal (26 ± 2°C) temperatures.

Abstract
Objective: To evaluate the predicting value of the 2014 European Society of Cardiology (ESC) guidelines risk prediction model for sudden cardiac death (HCM Risk-SCD) in Chinese patients with hypertrophic cardiomyopathy (HCM), and to explore the predictors of adverse cardiovascular events in Chinese HCM patients. Methods: The study population consisted of a consecutive 207 HCM patients admitted in our center from October 2014 to October 2016. All patients were followed up to March 2017. The 5-year SCD probability of each patient was estimated using HCM Risk-SCD model based on electrocardiogram, echocardiography and cardiac magnetic resonance (CMR) examination results. The primary, second, and composite endpoints were recorded. The primary endpoint included SCD and appropriate ICD therapy, identical to the HCM Risk-SCD endpoint. The second endpoint included acute myocardial infarction, hospitalization for heart failure, thrombus embolism and end-stage HCM. The composite endpoint was either the primary or the second endpoint. Patients were divided into the 3 categories according to 5-year SCD probability assessed by HCM Risk-SCD model: low risk group<4%,intermediate risk group ≥4% to<6%, and high risk group≥6%. Results: (1) Prevalence of endpoints: All 207 HCM patients completed the follow-up (350 (230, 547) days). During follow-up, 8 (3.86%) patients reached the primary endpoints (3 cases of SCD, 3 cases of survival after defibrillation, and 2 cases of appropriate ICD discharge); 21 (10.14%) patients reached the second endpoints (1 case of acute myocardial infarction, 16 cases of heart failure hospitalization, 2 cases of thromboembolism, and 2 cases of end-stage HCM). (2) Predicting value of HCM Risk-SCD model: Patients with primary endpoints had higher prevalence of syncope and intermediate-high risk of 5-year SCD, as compared to those without primary endpoints (both P<0.05). (3) Predicting value of HCM Risk-SCD model: The low risk group included 122 patients (59%), the intermediate risk group 42 (20%), and the high risk group 43 (21%). There was a clear trend towards to higher heart rate, higher values of PTF(V1) and plane QRS-T angle, higher left ventricular mass index (LVMI), elevated maximal left ventricular outflow tract pressure gradient (LVOT-PGmax), enlarged left atrial dimension(LAD) and volume index (LAVI), reduced systolic mitral annular velocity (s'), and higher late gadolinium enhancement (LGE) volume and mass in patients with high risk of 5-year of SCD, as compared to those with low-intermediate risk (all P<0.05). Moreover, 5-year SCD probability was positively correlated with heart rate, plane QRS-T angle, LVMI, LAVI, LGE%, and negatively correlated with s'(r=0.161, P=0.019; r=0.669, P=0.001; r=0.206, P=0.004; r=0.284, P=0.000; r=0.351, P=0.000; r= -0.245, P=0.001; respectively). (4) LAD, LAVI, e' and s' were independent predictors for poor outcomes. HCM patients with LAD≥39 mm, LAVI≥49.6 ml/m(2), e'≤6.5 cm/s and s'≤6.6 cm/s were more likely to have adverse cardiovascular events (AUC 0.702, 95%CI 0.604-0.799, P=0.001; AUC 0.700, 95%CI 0.567-0.833, P=0.001; AUC 0.716, 95%CI 0.616-0.817, P=0.000; AUC 0.764, 95%CI 0.676-0.853, P=0.000,respectively). Conclusions: The HCM Risk-SCD model is of value in predicting SCD for Chinese HCM patients. The plane QRS-T angle and LGE% are the best predictors of 5-year SCD risk in Chinese HCM patients. Moreover, conventional echocardiographic parameters, including LAD, LAVI, e' and s', are useful to predict adverse cardiovascular events among Chinese HCM patients.
