Abstract
Inflammatory bowel disease (IBD) is a chronic and incurable disorder associated with higher cancer risk and currently faces unsatisfactory treatment outcomes. Ferroptotic cells secrete damage-associated molecular patterns (DAMPs) that recruit and activate immune cells, particularly macrophages. Magnolin has excellent antioxidant and anti-inflammatory properties, but its effect on IBD has not yet been clearly understood. This study aimed to investigate the therapeutic effects and mechanism of magnolin in IBD. For this purpose, in vivo and in vitro colitis models were established using dextran sulfate sodium (DSS), followed by optimization of magnolin concentration 2.5 μg/mL in vitro and 5 mg/kg in vivo. Bioinformatics analysis identified potential magnolin target sites and evaluated ferroptosis-associated gene expressions. Body weight, food intake, disease activity index (DAI), pathological changes, and inflammation levels were assessed. The effect of magnolin on ferroptosis and macrophages was evaluated using quantitative real time-polymerase chain reaction (qRT-PCR), immunofluorescent staining, flow cytometry, enzyme-linked immunosorbent assay (ELISA), and western blotting. Results indicated that magnolin at a lower dose (5 mg/kg) alleviated DSS-induced colitis symptoms and reduced inflammation in mice. The bioinformatics analysis showed arachidonate 5-lipoxygenase (ALOX5) as a potential magnolin target. Furthermore, magnolin inhibited the expression of ALOX5 with no effect on GPX4. Moreover, magnolin regulated macrophage differentiation into the M2 phenotype and suppressed pro-inflammatory factors, that is, interleukin-6 and tumor necrosis factor-α (IL-6 and TNFα). These results suggested that magnolin possesses significant therapeutic potential in treating IBD by suppressing ALOX5-mediated ferroptosis, inhibiting M1 while promoting M2 macrophages, which is envisaged to provide novel strategies for treating IBD.

Abstract
Background The lung ultrasound score was developed for rapidly assessing the extent of lung ventilation, and it can predict failure to wean various types of patients off mechanical ventilation. Whether it is also effective for COVID-19 patients is unclear. Methods This single-center, prospective, observational study was conducted to assess the ability of the 12-region lung ultrasound score to predict failure to wean COVID-19 patients off ventilation. In parallel, we assessed whether right hemidiaphragmatic excursion or previously published predictors of weaning failure can apply to these patients. Predictive ability was assessed in terms of the area under the receiver operating characteristic curve (AUC). Results The mean age of the 35 patients in the study was (75 ± 9) years and 12 patients (37%) could not be weaned off mechanical ventilation. The lung ultrasound score predicted these failures with an AUC of 0.885 (95% CI 0.770-0.999, p < 0.001), and a threshold score of 10 provided specificity of 72.7% and sensitivity of 92.3%. AUCs were lower for previously published predictors of weaning failure, and right hemidiaphragmatic excursion did not differ significantly between the two groups. Conclusion The lung ultrasound score can accurately predict failure to wean critically ill COVID-19 patients off mechanical ventilation, whereas assessment of right hemidiaphragmatic excursion does not appear helpful in this regard.

Abstract
Destruction of the blood-brain barrier is a critical component of epilepsy pathology. Several studies have demonstrated that sphingosine 1-phosphate receptor 1 contributes to the modulation of vascular integrity. However, its effect on blood-brain barrier permeability in epileptic mice remains unclear. In this study, we prepared pilocarpine-induced status epilepticus models and pentylenetetrazol-induced epilepsy models in C57BL/6 mice. S1P1 expression was increased in the hippocampus after status epilepticus, whereas tight junction protein expression was decreased in epileptic mice compared with controls. Intraperitoneal injection of SEW2871, a specific agonist of sphingosine-1-phosphate receptor 1, decreased the level of tight junction protein in the hippocampus of epileptic mice, increased blood-brain barrier leakage, and aggravated the severity of seizures compared with the control. W146, a specific antagonist of sphingosine-1-phosphate receptor 1, increased the level of tight junction protein, attenuated blood-brain barrier disruption, and reduced seizure severity compared with the control. Furthermore, sphingosine 1-phosphate receptor 1 promoted the generation of interleukin-1β and tumor necrosis factor-α and caused astrocytosis. Disruption of tight junction protein and blood-brain barrier integrity by sphingosine 1-phosphate receptor 1 was reversed by minocycline, a neuroinflammation inhibitor. Behavioral tests revealed that sphingosine 1-phosphate receptor 1 exacerbated epilepsy-associated depression-like behaviors. Additionally, specific knockdown of astrocytic S1P1 inhibited neuroinflammatory responses and attenuated blood-brain barrier leakage, seizure severity, and epilepsy-associated depression-like behaviors. Taken together, our results suggest that astrocytic sphingosine 1-phosphate receptor 1 exacerbates blood-brain barrier disruption in the epileptic brain by promoting neuroinflammation.

Abstract
To explore the application value of whole exome sequencing (WES) in the diagnosis of prenatal and postnatal neurodevelopmental disorders (NDDs). A total of 70 patients diagnosed with NDDs who underwent WES at the Medical Genetics Center of the Maternal and Child Health Hospital of Hubei Province between June 2020 and July 2021 were retrospectively analyzed. Genomic DNA was extracted from peripheral blood samples and amniotic fluid. WES-based copy number variant (CNV) analysis was integrated into the routine WES data analysis pipeline. The results showed that a molecular diagnosis rate could be made in 21/70 (30%) cases. Of 21 positive cases, 14 (23%) cases were detected by single-nucleotide variant/small insertion/deletion (SNV/Indel) analysis, of which 12 variants were novel, 6 (9.8%) cases were detected by WES-based CNV analysis, and 1 (1.6%) case was detected by a combination of both. The diagnostic yield of WES combined with CNV analysis was higher than that of SNV/Indel analysis alone (30%, 21/70 vs. 20%, 14/70). Of the 28 prenatally diagnosed cases, 6 cases were found to have inherited parental variation for NDDs, 10 cases were found not to have the same pathogenic variation as the proband, and the remaining 12 cases were found to have no pathogenic or likely pathogenic variation that could explain the NDDs phenotype. Clinical follow-up showed that 5 families opted for abortion and the remaining had no current abnormalities. In conclusion, WES may be an effective method to clarify the genetic etiology and prenatal diagnosis of NDDs, which is helpful in assessing the prognosis to aid clinical management and reproductive guidance.

Abstract
Immunoglobulins (Igs) are important effector molecules that mediate humoral immunity. A typical Ig consists of two heavy and two light chains. In teleosts, three Ig heavy chain isotypes (Igμ, Igδ and Igτ) and three Ig light chain isotypes (Igκ, Igλ and Igσ) have been identified. Compared to the heavy chains, teleost Ig light chains have been poorly studied due to the lack of antibodies. In this study, a mouse anti-Nile tilapia Igλ monoclonal antibody (mAb) was prepared, which could specifically recognize Igλ in serum and Igλ+ B cells in tissues. Further, the composition of IgM+ and Igλ+ B cell subsets was analyzed using this antibody and a mouse anti-tilapia IgM heavy chain mAb. The ratio of IgM+Igλ+ B cells to total IgM+ B cells in head kidney and peripheral blood was about 30%, while that in spleen was about 50%; the ratio of IgM-Igλ+ B cells to total Igλ+ B cells in head kidney and peripheral blood was about 45%, while that in spleen was about 25%. The IgM-Igλ+ B cells was speculated to be IgT+ B cells. Finally, we detected an increase in the level of specific antibodies against the surface antigen-Sip of Streptococcus agalactiae in serum after S. agalactiae infection, indicating that mouse anti-tilapia Igλ mAb can be used to detect the antibody level after immunization of Nile tilapia, which lays a foundation for the evaluation of immunization effect of tilapia vaccine.

Abstract
Objective: To investigate the application and clinical efficacy of ultrasound debridement method in residual burn wounds. Methods: A retrospective cohort study was conducted. From August 2017 to August 2021, 64 patients with residual burn wounds who met the inclusion criteria were admitted to the 980th Hospital of the Joint Logistic Support Force of PLA. According to the debridement method adopted for the residual wounds, the patients were divided into ultrasound debridement group (34 cases, 22 males and 12 females, aged (31±13) years) and traditional debridement group (30 cases, 19 males and 11 females, aged (32±13) years). After the corresponding debridement, the wounds of patients in the two groups were selected for stamp skin grafting or large skin grafting according to the wound site and skin donor status. For unhealed wounds after stage Ⅰ surgery, secondary debridement and skin grafting were be performed, with the wound debridement methods in the 2 groups being the same as those of stage Ⅰ, respectively. On postoperative day 3, drug-sensitive test was used to detect the bacteria in the wound and the positive rate of bacteria was calculate. On postoperative day 7, the survival rate of skin slices in wound and the incidence of subcutaneous hematoma were calculated. At discharge, wound healing time and debridement times of patients were counted, and the secondary debridement rate was calculated. Data were statistically analyzed with independent sample t test or chi-square test. Results: On postoperative day 3, the wounds in ultrasound debridement group were infected with Staphylococcus aureus in 2 cases and Pseudomonas aeruginosa in 2 cases, and the wounds in traditional debridement group were infected with Staphylococcus aureus in 5 cases, Pseudomonas aeruginosa in 3 cases, Acinetobacter baumannii in 1 cases, Klebsiella pneumoniae in 1 cases, and Enterobacter cloacae in 1 cases. The positive rate of bacteria of wound in ultrasound debridement group was significantly lower than that in traditional debridement group (χ2=5.51, P<0.05). On postoperative day 7, the survival rate of skin grafts in ultrasound debridement group was (92±5) %, which was significantly higher than (84±10) % in traditional debridement group (χ2=6.78, P<0.01); the incidence of subcutaneous hematoma in ultrasound debridement group was 17.6% (6/34), which was significantly lower than 40.0%( 12/30) in traditional debridement group, χ2=3.94, P<0.05. At discharge, the wound healing time in ultrasound debridement group was (11.0±2.0) d, which was significantly shorter than (13.0±3.1) d in traditional debridement group (t=3.81, P<0.01); the secondary debridement rate of wounds in ultrasound debridement group was 2.9% (1/34), which was significantly lower than 20.0% (6/30) in traditional debridement group (χ2=4.76, P<0.05). Conclusions: Ultrasound debridement method can significantly reduce the bacterial load of residual burn wounds, reduce postoperative hematoma formation, and promote the survival of skin grafts to shorten the course of disease of patients.

Abstract
Disease problems will seriously restrict the sustainable development of aquaculture, and the environmental-friendly prevention strategies are urgently needed. Probiotics and quorum-quenching enzyme are innovative strategies to control bacterial diseases. Firstly, the bacteriostatic activity of Bacillus subtilis wt55 strain and quenching enzyme AiiO-AIO6 on the growth of Aeromonas veronii were tested in vitro, and the results showed wt55 inhibit the growth of A. veronii, but AiiO-AIO6 did not. Then, the synergistic effects of simple combination of B. subtilis wt55 and AiiO-AIO6 were evaluated next. The results showed this combination could improve the survival rate and significantly reduce the number of invasive A. veronii in gut after challenge compared to the other groups, corresponding to the lower intestinal alkaline phosphatase activity. One of its effect mechanisms is the combination could inhibit the growth of A. veronii in vitro; the other is direct immersion of germ-free zebrafish proved AiiO-AIO6 did not directly regulate the innate immune response of the host, but wt55 did it, and the simple combination group could significantly reduce the expression of nuclear factor kappa-B (NF-κB) and proinflammatory cytokine interleukin-1β (IL-1β), increase the expression of lysozyme gene; and the third is intestinal microbiota also plays a regulatory role: the gut microbiota from combination group could significantly inhibit the expression of IL-1β and NF-κB, and increased the expression of transforming growth factor-β (TGF-β) and lysozyme. Given the effectiveness of this simple combination, a B. subtilis quorum-quenching recombinant expression strain in which AiiO-AIO6 was surface displayed on the spores and secreted by vegetative cells was built. The results showed that the survival rate after challenge was lower than that of the group treated with AiiO-AIO6 or wt55 alone, and the expression of proinflammatory cytokine IL-1β and NF-κB were significantly higher. Our study demonstrated the effectiveness of B. subtilis and AiiO-AIO6 simple combination and established an efficient B. subtilis expression system.

Abstract
Objective: To investigate the clinicopathological and molecular genetic characteristics of tall cell variant and hobnail variant of papillary thyroid carcinoma (PTC). Methods: Twenty-one cases of tall cell variant (TCV-PTC) of PTC (TCV-PTC) and ten cases of hobnail variant of PTC (HV-PTC), as the highly aggressive group, were collected from Xuanwu Hospital from August 2009 to August 2015. Twenty-two cases of follicular variant and 21 classical PTC cases were included as control. Relevant clinical and pathologic data were obtained, and in some cases, paraffin samples were selected for gene mutation spectrum analysis using second generation sequencing. Results: There were 18 males and 56 females; 57 patients were younger than 55 years of age, and 17 patients were 55 years or older. The mean tumor size was 1.6 cm for the high-aggressive group (TCV-PTC and HV-PTC), 1.1 cm for the follicular subtype, and 1.6 cm for the classical type. There were 54 cases with thyroid capsule invasion, 24 cases with extra-thyroidal invasion, and 45 patients with lymph node metastases. Regional recurrence occurred in 7 cases, no recurrence in 54 cases, and 13 patients were lost to follow-up. The highly aggressive group was more likely to show extra-thyroidal invasion, lymph node metastases and recurrence than those with classical PTC (P<0.05). Within this cohort, BRAF V600E mutation was detected in 53 cases and TERT promoter mutation in 6 cases. Compared with the single mutation group and no mutation group, BRAF and TERT promoter co-mutation group was more commonly detected in older age, male, larger tumor size and more prone to extra-thyroid invasion (P<0.05). In addition, among BRAF and TERT co-mutation cases, the highly-aggressive group accounted for the highest proportion (5/6). Conclusions: TCV-PTC and HV-PTC, as highly-aggressive variants of PTC, show more aggressive biologic behavior (more lymph node metastasis, external thyroid invasion and recurrences) than the classical and follicular variants of PTC. Coexisting BRAF and TERT promoter mutations may be associated with invasive biologic behavior.

Abstract
Fatty liver and intestinal barrier damage were widespread in most farmed fish, which severely restrict the development of aquaculture. Therefore, there was an urgent need to develop green feed additives to maintain host liver and intestinal health. In this study, a probiotic pili-like protein, Amuc_1100 (AM protein), was anchored to the surface of Lactococcus lactis ZHY1, and the effects of the recombinant bacteria AM-ZHY1 on liver fat accumulation and intestinal health were evaluated. Zebrafish were fed a basal diet, high-fat diet, and high-fat diet with AM-ZHY1 (108 cfu/g) or control bacteria ZHY1 for 4 weeks. Treatment with AM-ZHY1 significantly reduced hepatic steatosis in zebrafish. Quantitative PCR (qPCR) detection showed that the expression of the lipogenesis [peroxisome-proliferator-activated receptors (PPARγ), sterol regulatory element-binding proteins-1c (SREBP-1c), fatty acid synthase (FAS), and acetyl-CoA carboxylase 1 (ACC1)] and lipid transport genes (CD36 and FABP6) in the liver were significantly downregulated (p < 0.05), indicating that AM-ZHY1 could reduce liver fat accumulation by inhibiting lipid synthesis and absorption. Moreover, supplementing AM-ZHY1 to a high-fat diet could significantly reduce serum aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels, indicating that liver injury caused by high-fat diets was improved. The expression of tumor necrosis factor (TNF)-a and interleukin (IL)-6 in the liver decreased significantly (p < 0.05), while IL-1β and IL-10 did not change significantly in the AM-ZHY1 group. Compared to the high-fat diet-fed group, the AM-ZHY1 group, but not the ZHY1 group, significantly increased the expression of intestinal tight junction (TJ) proteins (TJP1a, claudina, claudin7, claudin7b, claudin11a, claudin12, and claudin15a; p < 0.05). Compared to the high-fat diet group, the Proteobacteria and Fusobacteria were significantly reduced and increased in the AM-ZHY1 group, respectively. In conclusion, the recombinant bacteria AM-ZHY1 has the capacity to maintain intestinal health by protecting intestinal integrity and improving intestinal flora structure and improving fatty liver disease by inhibiting lipid synthesis and absorption. This study will lay a foundation for the application of AM protein in improving abnormal fat deposition and restoring the intestinal barrier in fish.

Abstract
Objective: To analyze the clinicopathological features of chordoid glioma. Methods: A total of 12 cases of chordoid gliomas from 2009 to 2020 in Xuanwu Hospital of Capital Medical University and General Hospital of Chinese People's Liberation Army were retrospectively analyzed. The clinical and imaging characteristics, pathologic and molecular characteristics were analyzed, and the relevant literature was reviewed. Results: All 12 patients (4 males and 8 females) aged from 25 to 67 years (mean 39 years) and mainly had a history of headache or/and vision loss. MRI showed that the lesions located in the third ventricle, and they showed abnormal enhancement. Pathologically, these 12 cases displayed the morphologic characteristics of chordoid gliomas, including papillary structures in two cases. Immunohistochemically, GFAP and vimentin were expressed in all 12 cases (12/12). TTF1 was also expressed in all cases (10/10). CD34 and CKpan were seen in 11 cases (11/12). EMA with dot-and/or-ring like positivity was seen in 9 cases (9/10). Tissues were available in nine chordoid gliomas for Sanger sequencing to detect PRKCA and IDH gene mutation, and eight cases (8/9) showed PRKCA gene D463H mutation. None of these cases showed IDH1 R132 and IDH2 R172 mutation. All 12 patients underwent surgery, and four were lost to follow up. The remaining eight patients were progression or recurrence free at last follow-up in January 2021. Conclusions: Chordoid gliomas have relatively distinguishing clinical and histopathological features. PRKCA gene mutation in chordoid gliomas can be considered as a biomarker for the diagnosis and differential diagnosis of chordoid gliomas, and may provide a direction for future targeted therapy.

Abstract
OBJECTIVE To investigate the spatio-temporal distribution characteristics of Oncomelania hupensis snail habitats in three cities of Suzhou, Wuxi and Changzhou along the Taihu Lake region, so as to provide technical supports for establishing a sensitive and highly effective surveillance and forecast system for schistosomiasis. METHODS Snail distribution data were collected from Suzhou, Wuxi and Changzhou cities from 1950 to 2018, and the changing trend for snail habitats were described over years. In addition, the clusters of snail habitats were detected using Kernel density analysis and SaTScan space-time scan analysis. RESULTS The number of snail habitats appeared a single-peak distribution in Suzhou, Wuxi and Changzhou cities from 1950 to 2018, which peaked in 1970 and then declined rapidly. There were 62.68% of snail habitats eliminated within 10 years after identification, of which 38.24% were eliminated at the year of identification. Kernel density analysis and SaTScan space-time scan analysis revealed that high-density clusters of snail habitats were mainly distributed in Kunshan City, Wuzhong District and Xiangcheng District from 1970 to 1980, and in Yixing City in 1990; since then, the clusters gradually shrank, and overall appeared a move from northeast to west of Taihu Lake. A total of 4 new clusters were detected after 1970, as revealed by space-time scanning of snail habitats. In current snail habitats, emerging snail habitats are mainly identified in Huqiu District (Dongzhu Town), Wuzhong District (Guangfu Town), Taicang City (Shaxi Town) and Jintan District, and re-emerging snail habitats are scattered in 7 districts. CONCLUSIONS The distribution of snail habitats are spatio-temporal aggregation in Suzhou, Wuxi and Changzhou cities. The monitoring and prediction of emerging and re-emerging snail habitats are the key points in the future.

Abstract
Background Septic acute kidney injury (AKI) causes a sharp deterioration of renal function, and it is a major reason for mortality in intensive care units. Although miR-21 has been proven to be dysregulated in patients with sepsis, the evidence is scarce concerning its role in mediating cellular apoptosis in AKI. Methods Mice were injected intraperitoneally with 10 mg/kg of lipopolysaccharide (LPS) to establish septic AKI model, miR-21 mimic and inhibitor were used to manipulate the expression of miR-21, the creatinine levels were detected by a creatinine assay kit, the renal cell proliferation and apoptosis were detected by MTT assay, flow cytometry assay and acridine orange/ethidium bromide (AO/EB) fluorescence staining, the renal function was evaluated by renal histology and tubular injury score, western blot analysis was used to detect the target protein levels. Several bioinformatics tools were performed to show the downstream target of miR-21, and further confirmed by luciferase reporter assay and caspase-3 activity assay. Results miR-21 silencing was able to promote renal function and decrease LPS-stimulated renal cell apoptosis in vitro and in vivo, and it could decrease the Bax/Bcl-2 ratio and caspase-3 activity. On the contrary, miR-21 overexpression had the opposite effects. Cyclin-dependent kinase 6 (CDK6) was confirmed as a target gene of miR-21 and was associated with renal cell apoptosis. Moreover, miR-21 was also found to be up-regulated in septic AKI. Conclusions Current evidences suggest that miR-21 has a potential application in treating septic AKI.

Abstract
Schistosomiasis was once heavily endemic in Jiangsu Province. Following the control efforts for several decades, schistosomiasis was almost eradicated in all endemic counties in Jiangsu Province in 1980, and transmission control was achieved in the province in 2011. According to the principle of "implementing the control measures with adaptation to local circumstances and guiding the control programs with classified interventions", an integrated strategy with emphasis on the management of both infectious sources and snails has been recently employed for schitsosomiasis control in Jiangsu Province. In addition, a sensitive and highly effective surveillance system has been built and the application of novel techniques and information construction has been intensified to effectively interrupt the transmission of schistosomiasis in the Province. Transmission interruption of schistosomiasis was achieved in all endemic counties in Jiangsu Province. The paper summarizes the endemic situation of schistosomiasis, progress of schistosomiasis control, and major schistosomiasis control measures implemented during the stage of transmission interruption in Jiangsu Province.

Abstract
The lectin pathway of complement activation is an important component of the innate immune response, which must be tightly controlled to maintain immune homeostasis. However, its control mechanisms have not been investigated in detail in bony fish. In this study, we identified and characterized two novel, phylogenetically conserved mannan-binding lectin (MBL)-associated proteins (MAps) of grass carp (Ctenopharyngodon idella), CiMAp27 and CiMAp39, which were truncated, alternatively-spliced forms of grass carp MBL-associated serine proteases (MASPs), CiMASP1 and CiMASP2, respectively. Gene expression profiling showed that both CiMAp27 and CiMAp39 were upregulated by low doses of Aeromonas hydrophila, and inhibited by high doses, which lead to the inference that these genes acted as immune factors in antibacterial defense. Sequence analysis showed that CiMAp27 lack a catalytic domain but retains two domains (CUB1-EGF) involved in the association with MBL, while CiMAp39 retained four domains (CUB1-EGF-CUB2-CCP1). Not only the two CiMASPs but also the CiMAps were detected in grass carp serum. Furthermore, both recombinant CiMASPs (rCiMASPs) and recombinant rCiMAps (rCiMAps) interacted with recombinant MBL and the two CiMAps competed with CiMASPs for binding to MBL, and hence inhibited downstream C4 binding. These results indicated that CiMAps acted as competitive inhibitors in the lectin complement pathway of grass carp.

Abstract
OBJECTIVE To evaluate the value of a dynamic automatic identification system in routine miracidium hatching test with nylon gauzes. METHODS Different quantities of fresh Schistosoma japonicum eggs were added to bovine fecal samples and divided into the low-infection group, medium-infection group and high-infection group, while the bovine feces without S. japonicum eggs served as negative controls. The detection efficiency and accuracy were compared between the identification system and manual detection in different groups. RESULTS The identification system can automatically identify S. japonicum miracidium. The detection rate and efficiency of S. japonicum miracidium in bovine fecal samples were both higher by using the identification system than by manual detection. Notably in the low-infection group, the identification system had a significantly higher rate of detection of S. japonicum miracidium than manual detection (χ2 = 10.769, P = 0.002). The identification system completed the detection of bovine fecal samples in the field within 1 min. CONCLUSIONS The dynamic automatic identification system may effectively improve the detection efficiency and accuracy of routine miracidium hatching test with nylon gauzes, and it may replace manual detection to be used in the field schisotsomiasis examinations and related researches.

Abstract
OBJECTIVE To analyze and investigate the changing trend of the endemic situation of schistosomiasis in national surveillance sites of Jiangsu Province from 2011 to 2018, so as to provide scientific evidence for formulating strategies for schistosomiasis control. METHODS From 2011 to 2014, the national schistosomiasis surveillance sites were set in seven schistosomiasis endemic counties (cities, districts) across Jiangsu Province as according to the National Schistosomiasis Surveillance Scheme (2011 version), and from 2015 to 2018, the national surveillance sites were assigned in all 64 counties (cities, districts) endemic for schistosomiasis in Jiangsu Province according to the National Schistosomiasis Surveillance Scheme (2014 version). Schistosoma japonicum infections in local populations, mobile populations and livestock, and snail status were monitored in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and the monitoring data were statistically analyzed. RESULTS The sero-prevalence of S. japonicum infections was 1.50% to 4.61% among local populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and a higher sero-prevalence was seen in men than in women, with the sero-positives predominantly detected in local populations at ages of over 50 years. The positive rate of stool examinations was 0 to 0.14% among sero-positive local populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no acute case was found in local populations during the study period. The sero-prevalence of S. japonicum infections was 0.46% to 15.97% among mobile populations in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no egg-positives were identified. A total of 1 453 livestock were tested in the national schistosomiasis surveillance sites of Jiangsu Province from 2011 to 2018, and no S. japonicum infections were detected. During the period from 2011 through 2018, snail survey was conducted in an area of 216 million m2 in the national schistosomiasis surveillance sites of Jiangsu Province, and 1 291.01 hm2 snail habitats were identified, with snail densities ranging from 0.01 to 0.47 snails/0.1 m2; however, no S. japonicum infections were identified in snails. CONCLUSIONS The overall endemic situation of schistosomiasis appears a tendency towards a decline in Jiangsu Province, and S. japonicum infection remains at a low level in both humans and livestock. No S. japonicum infection has been identified in local populations in Jiangsu Province since 2012. In the future, monitoring and management of imported sources of S. japonicum infections should be intensified in Jiangsu Province, and the capability building of passive surveillance of schistosomiasis should be improved in sentinel hospitals in national schistosomiasis surveillance sites of Jiangsu Province. In addition, the examination of schistosomiasis should be strengthened in mobile populations in Jiangsu Province, a sensitive and effective surveillance-response system for schistosomiasis is urgently needed.

Abstract
OBJECTIVE To construct the schistosomiasis diagnostic reference laboratory in Jiangsu Province, and to examine the role and diagnostic efficiency of the reference laboratory. METHODS A schistosomiasis diagnostic reference laboratory was built in Jiangsu Province according to the requirements of the construction of the national schistosomiasis diagnostic reference laboratory in China. Inter-laboratory comparisons were conducted and the diagnostic capability of grassroots laboratories was evaluated in Jiangsu Province. RESULTS The organization structure, environmental conditions, administration and quality systems of the schistosomiasis diagnostic reference laboratory in Jiangsu Province all met the requirements for construction of the national schistosomiasis diagnostic reference laboratory in China, and the schistosomiasis diagnostic reference laboratory in Jiangsu Province was issued a certificate of a province-level schistosomiasis diagnostic reference laboratory. During the 6 inter-laboratory comparisons performed by national schistosomiasis diagnostic reference centers of China, the qualitative and quantitative results of each detection item were all in agreement with the reference samples (Kappa = 1), and the diagnostic capability was identified excellent. The results of indirect hemagglutination assay of 426 serum samples from 4 grassroots laboratories were re-examined, and the mean coincidence rate was 94.13% (range, 92.08% to 96.25%) with the grassroots laboratories, with a mean Kappa value of 0.85 (range, 0.83 to 0.86) and a mean missing rate of 10.19% (range, 0 to 17.65%). CONCLUSIONS The schistosomiasis diagnostic reference laboratory has been successfully established and effectively operated in Jiangsu Province, which plays an active role in improving the capability of schistosomiasis diagnostic equality in the province.

Abstract
Aeromonas hydrophila is a pathogen that causes high mortality in the grass carp. The complement system, as a frontline defence of innate immunity, plays an important role in the immune response against pathogens. However, the immunity evasion mechanism of A. hydrophila against the complement system of grass carp remains unclear. In this study, we described an additional mechanism used by A. hydrophila GD18 to evade the complement system and survive in grass carp serum. First, A. hydrophila evaded the bactericidal activity of grass carp serum. Second, the haemolytic activity assays showed that A. hydrophila obviously suppressed the alternative pathway, which depended on preventing the formation or disabling the function of the membrane-attack complex (MAC). Further research indicated that A. hydrophila targeted complement C3, the central component of the three complement pathways, and degraded it in the grass carp serum, leading to the inhibition of the complement pathways, which resulted in the serum-resistance of A. hydrophila. Furthermore, cleavage analyses showed that extracellular proteases (ECPases) of A. hydrophila efficiently cleaved purified C3 as well as C3 in grass carp serum. Finally, protease inhibitor studies and mass spectrum analysis identified the secreted metalloprotease elastase (AhE), which was present in large amounts in crude ECPases, as the central molecule responsible for C3 cleavage. Compared to wild strain GD18, the AhE knockout, Δahe was dramatically reduced in the ability of serum resistance. Our findings suggested that A. hydrophila escaped serum-killing by suppressing the complement pathways via the degradation of complement C3 in bony fish, which was related to secreted metalloproteases.

OBJECTIVE To assess the total factor productivity (TFP) of schistosomiasis control programs in Jiangsu Province, so as to provide insights into sustainable schistosomiasis control. METHODS The data envelopment analysis-Malmquist index method was employed to analyze the human resources and financial investments in schistosomiasis control programs from health sectors in each schistosomiasis-endemic city of Jiangsu Province from 2005 to 2015, and assess the outputs of each schistosomiasis control project. RESULTS The overall productive efficiency of schistosomiasis control programs in Jiangsu Province showed an increasing tendency, and the mean fluctuation of annual TFP was 2.3%. The comprehensive technical efficiency, including pure efficiency and scale efficiency, appeared a steady increase with minor fluctuations, and the mean fluctuation of annual comprehensive technical efficiency was 3.8%. The growth rate of technical progress fluctuated greatly from 2005 to 2011, and showed a steady increase from 2012 to 2015, which became a major contributor to the growth of TFP. A higher growth rate of TFP was seen in Huai ' an and Changzhou cities, which showed a greater comprehensive technical efficiency, and a large fluctuation was observed in the growth rate of technical progress in Yancheng, Nanjing, Huai ' an and Yangzhou cities. CONCLUSIONS There is a continuous improvement in the technical level of schistosomiasis control programs in Jiangsu Province, and technical application and supervision and management capacity also show a steady increase. In addition, the application of new techniques and new strategies contributes greatly to TFP growth. In the future, the investment into new techniques and new strategies should be increased to ensure the sustainable schistosomiasis control in Jiangsu Province.

Abstract
Streptococcus agalactiae infections are becoming an increasing problem in aquaculture because of significant morbidity and mortality, which restricts the healthy development of tilapia aquaculture. To seek safe and effective prevention measures, a Bacillus subtilis GC5 surface displayed vaccine was prepared and applied orally in tilapia. The study first showed that recombinant spores can engraft in the tilapia intestine. Then, the effect of protection and the immune responses were evaluated. The results of ELISA showed that Sip-specific antibody in the sera of GC5-Sip-immunized fish can be detected after the first oral administration when compared to the phosphate buffer saline (PBS) control group, and the levels of specific IgM gradually strengthened with boosting, so does the specific antibody against bacteria, proving that humoral immunity was induced. Quantitative real-time PCR (qRT-PCR) results showed that the immune-related gene expression of the gut and spleen exhibited a different rising trend in the GC5-Sip group, revealing that innate immune response and local as well as systemic cellular immunity were induced. The outcome of fish immunized with GC5-Sip spores provided a relative percent survival (RPS) of 41.7% against S. agalactiae and GC5 group had an RPS of 24.2%, indicating that GC5-Sip was safe and effective in protecting tilapia against bacterial infection. Our study demonstrated that the oral administration of B. subtilis spores expressing Sip could cause an effective immune response and offer good resistance to bacterial infection. Our work may lead to the development of new ideas for immunoprophylaxis against S. agalactiae infection.

Abstract
The space cold atom clock (CAC) suffers more degradation of frequency stability from the local oscillator noise compared with fountain clocks operating on the ground because of the larger dead time of the clock cycle. Therefore, low phase noise is required for the microwave source of the space CAC in addition to robustness, compactness, and adaptability to the space environment. This paper presents the design and measurements of a low-phase-noise space qualified microwave source for the cold atom clock experiment in space CAC operating in the Tiangong-2 Chinese space laboratory. At frequencies near the carrier, a phase noise level of 10-6.7 × f -1.5 rad2/Hz (f is the Fourier frequency) is achieved. This guarantees a frequency stability of 1.4 × 10-13 τ -1/2 (τ is the average time in seconds) for the typical space CAC operation cycle.

Abstract
Atomic clocks based on laser-cooled atoms are widely used as primary frequency standards. Deploying such cold atom clocks (CACs) in space is foreseen to have many applications. Here we present tests of a CAC operating in space. In orbital microgravity, the atoms are cooled, trapped, launched, and finally detected after being interrogated by a microwave field using the Ramsey method. Perturbing influences from the orbital environment on the atoms such as varying magnetic fields and the passage of the spacecraft through Earth’s radiation belt are also controlled and mitigated. With appropriate parameters settings, closed-loop locking of the CAC is realized in orbit and an estimated short-term frequency stability close to 3.0 × 10−13τ−1/2 has been attained. The demonstration of the long-term operation of cold atom clock in orbit opens possibility on the applications of space-based cold atom sensors. Cold atom clocks are among the most precise measuring devices and play key roles in everyday life and scientific explorations. Here the authors demonstrate the first in-orbit atomic clock using cold Rb atoms operating in microgravity and opening possibilities of space surveys and tests of fundamental physics.

Abstract
We studied the content of chemical compositions and correlation among species of Tripterygium genus by principal component analysis(PCA) and variance analysis(ANOVA), and we also studied the difference among the 3 species.Using [BMIm]PF6 ionic liquid-based ultrasonic-assisted extraction, we determined the contents of 11 compounds including wilforgine, wilforzine, triptophenolide, wilforine, triptoquinone A, triptolide, tripterin, egallocatechin, epigallocatechin, catechin, and epicatechin in 28 batches of the Tripterygium species by HPLC and PCA. Partial least squares analysis (PLS) and ANOVA were also performed to verify the results.The analysis results of PCA and PLS showed that three species of Tripterygium genus were clustered into three regions respectively, and triptoquinone A was the important factor which affected the aggregation of these three species.There was a significant difference among the contents of 11 chemical components in the three species(P<0.000 1).These results indicated that there was a certain correlation between the chemical compositions and the classification of the species, and the difference of the chemical compositions among the three species was obvious. In this work, the content determination method is rapid and accurate, and the analysis method is simple and convenient, which provides a reference for the classification, the efficacy and the toxicity of the species.

Abstract
Grass carp reovirus II (GCRV II) causes severe hemorrhagic disease with high mortality in grass carp, Cyenopharyngodon idellus. DNA vaccination has been proven to be a very effective method in conferring protection against fish viruses. However, DNA vaccines for GCRV II have not yet been conducted on grass carp. In the current work, we vaccinated grass carp with a DNA vaccine consisting of the segment 6 (pC-S6; encoding VP4) or 10 (pC-S10; encoding NS38) of GCRV II and comparatively analyzed the immune responses induced by these two vaccines. The protective efficacy of pC-S6 and pC-S10, in terms of relative percentage survival (RPS), was 59.9% and 23.1% respectively. This suggests that pC-S6 and pC-S10 DNA vaccines could increase the survival rate of grass carp against GCRV, albeit with variations in immunoprotective effect. Immunological analyses indicated the following. First, post-vaccination (pv), both pC-S6 and pC-S10 up-regulated the expression of interferon (IFN-1), Mx1, IL-1β, and TNF-α. However, CD4 and CD8α were up-regulated in the case of pC-S6 but not pC-S10. Second, comparing non-vaccinated and pC-S10-vaccinated fish, the T cell response related genes, such as CD4, CD8α, and GATA3, were elevated in pC-S6-vaccinated fish at 48 h post-challenge (pc). Third, pC-S6 and pC-S10 induced similar patterns of specific antibody response pv. However, only anti-VP4 IgM in the sera of surviving fish infected with GCRV was significantly increased pc compared with that pre-challenge. Taken together, these results indicate that pC-S6 promotes both innate (IFN-1 and Mx1 induction) and adaptive (T cell and specific antibody response) immunity pv and that the induction of a memory state promptly primes the immune response upon later encounters with the virus, whereas pC-S10 only induces the type I IFN-related response pv and a lower inflammatory response pc.

Abstract
In this study, polylactic acid (PLA) disks with antibacterial performances were prepared using 3D printing technology combined with direct adsorption of the antibiotic agents in solution baths. The effects of the layer thicknesses for the building of the 3D printing PLA disks and the amounts of antibiotic agents absorbed onto the sample surfaces on their antibacterial activities were investigated. The antibiotic agent release profiles from the samples surface into the buffer solution show that the antibacterial performances of these samples can reach up to 28 days. With a decrease in the concentration of antibiotic agent in the solution bath, the amount of antibiotic agent adsorbed on the sample surfaces also decreases, but their antibacterial performances can still maintain at least 7 days. In the bioactivity tests of the various organisms, the release amount of antibiotic agent from the sample can inhibit E. coli and S. aureus for over 80% up to 28 days. In the antibacterial activity tests, a PLA disk with suitable antibiotic agents covering its surface has a good inhibitory effect on the growth ability of S. aureus of less than 50% in six hours. In this study, we developed a surface modification of 3D printing PLA disks. The relative optical density of the S. aureus in the solution can reduce to 40% using the PLA disk directly absorbed with suitable antibiotic agents.![]()

Abstract
Using six kinds of ionic liquids as extractants, ultrasonic-assisted extraction coupled with HPLC method was developed for the simultaneous determination of wilforgine, wiforizine, triptophenolide, wilforine and triptoquinone A in Tripterygium hypoglaucum. The separation was performed on an Inertsil ODS-4 column with the mobile phase of acetonitrile-0.1% phosphoric acid in gradient elution at a flow rate of 0.75 mL•min⁻¹. Detection wavelength was 220 nm and the column temperature was 30℃. Under the optimal extractions, the results showed that triptophenolide and triptoquinone A had the highest extraction yield by using 0.6 mol•L⁻¹ [BMIm]PF6 methanol solution as extraction solvent with the solid-liquid ratio of 1∶10. The calibration curves of triptophenolide and triptoquinone A showed a good linearity in the range of 0.000 65-0.026, 0.066 55-2.662 μg (r=0.999 9)respectively. The average recovery was 102.4% and 97.90% with RSD of 2.5% and 1.5%, respectively. Wilforgine, wiforizine and wilforine had the highest extraction yield when using 0.6 mol• L⁻¹ [BMIm]PF6absolute ethanol solution as extraction solvent with the solid-liquid ratio of 1∶10. The content of wilforgine, wiforizine and wilforine from 0.023 9-0.956, 0.002 7-0.108, 0.006 4-0.256 μg showed a good linearity (r=0.999 9), and the average recovery was 100.6%,99.50% and 98.70% with RSD of 2.1%,1.9% and 2.7%, respectively. The results indicated that this method is convenient, reliable and green, and can be used as a reliableanalytical method for the quality control of T.hypoglaucum.

Abstract
BACKGROUND The purpose of this study was to compare the surgical outcomes of a Colorado microdissection needle (CMN) with that of a standard-size electrocautery needle in one-stage hypospadias repair using a transverse preputial island flap (TPIF). METHODS The records of patients who received hypospadias repair from September 2012 to October 2013 were retrospectively reviewed. Patients were divided into a group that received repair using a CMN and those in which a standard-size electrocautery needle was used. Data collected and compared included age, types of hypospadias, duration of surgery, intraoperative blood loss, and postoperative edema and complications. RESULTS There were 51 patients in the CMN group and 44 in the standard needle group, and the groups were similar with respect to age and type of hypospadias. The median surgery time for the CMN group was significantly shorter than that of the standard group (15.7 minutes vs. 20.6 minutes, respectively, P<0.001). At postoperative day 7 and day 30, the CMN group had significantly less patients with edema than the standard needle group (31.4% vs. 65.9%, P<0.01; and 37.3% vs. 79.5%, P<0.001, respectively). The overall complication rate has no significant difference between two groups. CONCLUSIONS The use of CMN for tissue dissection and separation in hypospadias repair can facilitate foreskin degloving, shape the flap in a more efficient way, and help maintain adequate blood supply for the new urethra and its skin coverage.

Abstract
AIM: To investigate the effect of combined transfection of short hairpin RNAs (shRNAs) targeting survivin and CD44v3 on cell proliferation and invasion in human colorectal carcinoma cell line SW480 and to provide experiment evidence for gene therapy of colorectal carcinoma.
METHODS: Plasmids carrying shRNAs targeting survivin and CD44v3 were designed, constructed and transfected into SW480 cells. SW480 cells were divided into negative control group, blank control group, survivin shRNA group, CD44v3 shRNA group and co-transfection group. Survivin and CD44v3 protein expression was analyzed by Western blot. Cell apoptosis, proliferation and invasion were measured by flow cytometry, MTT assay and Transwell chamber assay, respectively.
RESULTS: The expression of survivin and CD44v3 proteins in the co-transfection group was reduced by 84.2% ± 0.3% and 77.3% ± 0.1%, respectively. Co-transfection inhibited protein expression more efficiently than single-plasmid transfection (P < 0.05). After transfection for 120 h, the reduced rate of cell growth was 44.3% ± 0.1% in the co-transfection group, 21.5% ± 0.2% in the survivin shRNA group, and 26.4% ± 0.2% in the CD44v3 shRNA group. Combined transfection inhibited cell proliferation more efficiently than single-plasmid transfection (P < 0.05). The overall apoptosis rate was 37.6% ± 2.3% in the co-transfection group, 20.0% ± 0.4% in the survivin shRNA group, and 21.6% ± 1.6% in the CD44v3 shRNA group. Combined transfection induced cell apoptosis more efficiently than single-plasmid transfection (P < 0.05). The number of cells passing the Transwell chamber was 66.12 ± 4.04 in the co-transfection group, 89.35 ± 3.06 in the survivin shRNA group, and 93.53 ± 5.13 in the CD44v3 shRNA group. Combined transfection reduced cell invasion more significantly than single-plasmid transfection (P < 0.05).
CONCLUSION: Transfection of either survivin shRNA or CD44v3 shRNA could significantly inhibit cell proliferation, reduce cell invasion and induce cell apoptosis in human colorectal carcinoma cell line SW480. Co-transfection of survivin and CD44v3 shRNAs has a synergistic effect in inhibiting proliferation and weakening invasion of SW480 cells.

Abstract
Hepatitis B virus (HBV) infection exhibits a very narrow host range and shows a strong tropism for liver parenchymal cells, however none of the previously established experimental models can reproduce the natural process of HBV infection. In the present study, primary human hepatocytes were fused with HepG2 cells to establish the hybrid HepCHLine-4 cell line with high susceptibility to HBV. The HepCHLine-4 cells expressed HBV-specific antigen when co-incubated with HBV-positive serum from a hepatitis B patient. Post-infection, HBV relaxed circular DNA and covalently closed circular DNA were detected in HepCHLine-4 cells using a nested polymerase chain reaction, and HBV-specific particles were visualized by electron microscopy of the culture media of HepCHLine-4 cells. HepG2 cells were not susceptible to HBV infection under the same conditions. The HepCHLine-4 cells can be sub-cultured for > 12 months while maintaining susceptibility to HBV and may, therefore, be useful for studying HBV infection and the viral life cycle in human hepatocytes.

Abstract
The aberrant expression of tissue factor (TF) in acute promyelocytic leukemia (APL) cells has been implicated in the pathogenesis of the APL coagulopathy. In this study, we found that in APL patients receiving ATRA or As2O3 treatment, the improvement in hypercoagulobility and hyperfibrinolysis paralleled the correction of plasma fibrinogen level and amelioration of bleeding symptoms. Notably, clinical improvement was also correlated to ATRA/As2O3-induced rapid decrease of membrane procoagulant activity (PCA) and TF contents of APL blasts. Consistent with the in vivo findings, the membrane PCA, TF antigen and its mRNA level within NB4 cells were rapidly down-regulated by 1 microM ATRA or As2O3, while 0.2 microg/ml DNR increased these TF parameters prior to its effect upon apoptosis induction. The down-regulation of TF mRNA by ATRA was partially de novo protein synthesis-dependent and at least partially attributed to a mechanism of destabilizing TF mRNA. On the other hand, in addition to its modulation on mRNA, As2O3 could also induce an accelerated TF protein turnover. These distinct effects were corroborated with the properties of these agents in causing the degradation of PML-RARalpha protein. All three therapeutic agents, however, enhanced the potential of NB4 cells to stimulate the expression of TF and PCA in endothelium. Taken together, our data suggest that the rapid and distinct regulation of TF on APL cells by these therapeutic agents might at least partially contribute to their effects on APL coagulopathy.

Abstract
AIM To study the effects of indometacin (Ind) on joint damages. METHODS The volume of noninjected hind paw and interleukin-1 (IL-1) production from peritoneal macrophages and articular synoviocytes induced by lipopolysaccharides were assayed in adjuvant arthritis (AA) rats. Measurements of synovial fibroblast proliferative response and proteoglycan synthesis of cartilage from rabbits were used. RESULTS The secondary inflammatory reactions in AA rats on d 18, 21, and 24 were suppressed by i.g. Ind 2 mg.kg-1.d-1 for 9 d. Ind promoted IL-1 production from both macrophages and synoviocytes in AA rats. Ind 10 mumol.L-1 enhanced the proliferation of rabbit synovial fibroblasts and suppressed the proteoglycan synthesis of articular cartilage in response to IL-1 in vitro. CONCLUSION Ind is unfavorable to the repair of joint destruction.
