Abstract
1. The role of melanoma differentiation-associated protein 5 (MDA5) in infectious bursal disease virus (IBDV)-induced autophagy was studied in chicken embryos.2. Chicken embryo fibroblasts (CEF) were used as the research model and small interfering RNA (siRNA), western blot, indirect enzyme-linked immunosorbent assay (ELISA), real-time fluorescence quantitative polymerase chain reaction (PCR) and transmission electron microscopy were used to detect autophagy, IBDV replication, CEF damage, and activation of both MDA5 and its signalling pathway.3. The results showed that CEF infected with IBDV activated the intracellular MDA5 signalling pathway and caused autophagy via inactivation of the AKT/mTOR pathway. While autophagy promotes IBDV proliferation, MDA5 weakens IBDV-induced CEF autophagy thus inhibiting IBDV replication and protecting CEF cells.4. The results indicated that chMDA5 can be activated by IBDV and attenuate CEF autophagy caused by IBDV infection, thereby inhibiting IBDV replication. This study provided a foundation for further exploring the relationship between viruses, autophagy and the pathogenic mechanism of the MDA5 pathway involved in IBDV.

Abstract
Abstract
Study question
Is the morphological grading systems of a blastocyst associated with perinatal outcomes in women undergoing frozen-thawed single blastocyst transfer (SBT)?
Summary answer
Preferential transfer of a blastocyst based on their morphological grading systems appears to be supported by observed differences in perinatal outcomes.
What is known already
The transfer of a morphologically good quality blastocyst is associated with higher implantation and pregnancy rates as compared with a poor quality blastocyst. However to date, the association of the morphologic parameters of the blastocyst (developmental stage, inner cell mass (ICM), and trophectoderm (TE)) with the perinatal outcomes after blastocyst transfer remains unknown.
Study design, size, duration
A retrospective cohort study including 21,648 frozen-thawed SBT cycles from January 2013 to March 2019.
Participants/materials, setting, methods
6037 women with singleton delivery in Peking University Third Hospital were eligible for analysis. Multivariate logistic regression was used to test the risk of factors with the expression of crude odds ratios (OR) and adjusted OR (aOR) with 95% confidence intervals (CI).
Main results and the role of chance
Transfer of a blastocyst with grading lower than 3BB was associated with a higher chance of female baby (49% vs 43%, aOR = 1.27 (1.12, 1.43)) and a higher rate of cesarian section (C-section) (69% vs 65%, aOR = 1.17 (1.03, 1.34)). Compared with stage 4 blastocyst, transfer of a stage 3 blastocyst was associated with a higher chance of preterm delivery (PTD) (aOR = 1.77 (1.08, 2.90)). Both stage 3 and stage 6 blastocyst transfer was associated with a lower chance of female baby (aOR = 0.68 (0.48, 0.97), 0.66 (0.47, 0.93), respectively). Compared with grade A ICM blastocyst transfer, Grade B ICM and grade C ICM blastocyst transfer was associated with a lower chance of a female baby (adjusted OR = 0.84 (0.73, 0.96), 0.63 (0.48, 0.83), respectively) and a higher risk of large for gestational age (LGA) (aOR = 1.20 (1.01, 1.42), 1.46 (1.07, 1.98), respectively). Grade C ICM blastocyst transfer was associated with an increased risk of macrosomia (aOR = 1.66 (1.14, 2.42)).Grade B TE and grade C TE blastocyst transfer had a lower risk of gestational diabetes mellitus (GDM) (aOR = 0.76 (0.60, 0.98), 0.69 (0.50, 0.94), respectively) than grade A TE blastocyst transfer.
Limitations, reasons for caution
The main limitations of this study were its retrospective nature and the relative subjectivity of blastocyst scoring. The follow-up was conducted through a phone call and some patients might not report their obstetrical and neonatal outcomes, leading to a relatively lower rate of several obstetrical outcomes.
Wider implications of the findings: Transfer of a poor quality blastocyst is associated with a higher rate of C-section. The association between ICM grading and LGA and macrosomia would suggest that blastocysts with grade A ICM grading should be transferred preferentially and supports the use of current morphological grading systems for embryo prioritisation.

Abstract
Objective: To explore the effect of different calcium intakes on metabolism in healthy adults with traditional Chinese dietary pattern. Methods: A total of 64 college students (32 males and 32 females) were recruited from the School of Public Health, Harbin Medical University from September to October 2015. A prospective, randomized, double-blind, placebo-controlled trial design (RCT trial) was used to strictly control the diet of the volunteers through meal preparation, so that the background of the experimental and the control group was exactly the same. In our study, 64 healthy adults were randomly divided into two groups (calcium supplementation and control). The two groups were given the same diet every day. One group was given 400 mg/d of calcium supplementation, which was close to the recommended intake in China (800 mg/d); the other group was given pacebo, the average calcium intake was close to the average intake of Chinese (400 mg/d), calcium intervention lasted for 35 days. Serum and urine samples from pre-intervention, mid-intervention, and post-intervention were collected for metabolomics studies and detection of serum hormone levels and biochemical indicators. PCA and PLS-DA were used to compare the differences in serum and urine metabolites. After adjusting for age and BMI, the differences of hormones [parathyroid hormone, 1, 25(OH)2D3] and biochemical indicators were compared by repeated measurement variance analysis. Results: The 64 subjects were aged 23-28 years, including 32 males and 32 females. The baseline characteristics of the calcium supplementation group and the control group were balanced. The results showed that there were no significant differences in blood and urine metabolites, metabolic hormone [parathyroid hormone, 1, 25(OH)2D3] levels and biochemical indicators(serum Ca, serum P, glycolipid metabolism and hepatorenal function indicators)between the calcium supplementation group and control group at each time point throughout the trail (P>0.05). Conclusion: No health hazards associated with calcium deficiency was observed in healthy adults in the short term at current calcium intake level (300-400 mg/d).

Abstract
Abstract
Study question
what is the source, prevalence, and influence of microbial contamination on in vitro fertilization (IVF) and embryo transfer (ET) cycles?
Summary answer
Microbial contamination mainly occurs on Day 2, most caused by Escherichia coli carried with semen. ICSI could prevent contamination effectively and get good clinical outcomes.
What is known already
Microbial contamination occurs in IVF-ET system occasionally, which is hard to stop happening. The IVF culture system and laboratory environment, the patients’ follicular fluid and semen are not absolutely sterile, while the antibiotics in culture medium isn’t effective for all microbe types, and the artificial operations may bring in microbes. Generally, microbial contamination leads to degradation of embryos, reduction the number of embryos available, and infection of female reproductive tract, which would increase the cost of patients’ time, money, and bring psychological damages. A better understanding of embryo contamination in IVF culture system is of added value.
Study design, size, duration
A total of 29583 IVF-ET cycles were enrolled in this prospective observational study, from January 2010 to December 2020, included 70 microbial contamination cycles discovered in Day1-Day3 (D1-D3) of in vitro culture. Follicular fluid and semen saved on oocyte retrieval day, and culture medium contaminated were examined and identified for microorganisms at each contamination cycle.
Participants/materials, setting, methods
Compared the contamination rate of different insemination methods (IVF/ICSI/IVF+ICSI), different in vitro culture days (D1-D3), and different samples examination (follicular fluid, semen, culture medium) respectively, identified the source of microorganism types, compared the IVF culture outcomes and clinical outcomes between total contamination group (TC group, 42 cases) and partial contamination group (PC group, 28 cases).
Main results and the role of chance
A total of 70 microbial contamination cases occurred in 29583 oocyte retrieving cycles (0.24%), and it was observed only in IVF embryos but never in ICSI (Intracytoplasmic sperm injection) embryos. 38 contamination cases occurred on D2 with a highest ratio (54.3%) compared to D1 (32.9%) and D3(12.9%); Compared with follicular fluid, semen was the main cause inducing contamination from D1 to D3, and Escherichia coli in semen and culture medium, Enterococcus faecalis in follicular fluid proved to be the most common sources. Compared with TC group, the PC group showed a lower rate of No-available embryos (21.4% vs 81.0%) and a higher rate of blastocyst formation (41.2% vs 28.6%), In addition, the clinical pregnancy rate of PC group was higher than that of TC group in both fresh and frozen-thawed embryo transfer cycles (31.3% vs 16.7%, 38.5% vs 0.0%).
Limitations, reasons for caution
Further study is still necessary to better understand the sources that induce microbial contamination embryos, and more efficient methods are required to remove the microbes on these contaminated embryos so as better develop and manage a sterile micro-environment for successful embryo growth.
Wider implications of the findings: The differential embryonic microbe types associated to different IVF culture and clinical outcomes in patients undergoing IVF-ET might have profound implications for understanding the microbial sources and making a better management of IVF culture system.

Abstract
BACKGROUND The study examines the function of hypoxia-mediated down-regulation of microRNAs (miRNAs) (mir-30c, mir-135a, and mir-27a) in the process of bladder cancer immune escape. METHODS Quantitative Real-time PCR (qRT-PCR) was carried out to determine gene expression levels of Drosha and Dicer under hypoxia treatment, while western blotting and flow cytometry were used to determine protein expression. Seven reported miRNAs were identified via qRT-PCR assay. Flow cytometry detection of CD3/CD4/CD8-positive expression and statistics. Enzyme-linked immunosorbent assay (ELISA) detected cellular immune factors content. Cell apoptosis was checked via flow cytometry assay. Luciferase report assay and western blot assays were both used to verify the relationship between miRNAs and Casitas B-lineage lymphoma proto-oncogene b (Cbl-b). The animal model was established and Hematoxylin-eosin (HE) staining, TdT-mediated dUTP Nick-End Labeling (TUNEL) staining, and immunohistochemistry (IHC) assays were separately used to verify the conclusions. RESULTS The CD3 + /CD4 + expression was increased in the hypoxia group, while CD3 + /CD8 + expression, the cellular immune factors content Interleukin-2 (IL-2) and Tumor Necrosis Factor-α (TNFα) along with the cell apoptosis were suppressed. The protein expression of Cbl-b was found to be up-regulated in the hypoxia group. After constructing the overexpression/ knockdown of Cbl-b in peripheral blood mononuclear cell (PBMC), Cbl-b has been found to promote tumor immune escape in bladder cancer. Furthermore, Cbl-b had been identified as the co-targets of mir-30c, mir-135a, and mir-27a and down-regulation of miRNA biogenesis promotes Cbl-b expression and deactivating T cells in vitro/in vivo. CONCLUSION Hypoxia-mediated down-regulation of miRNAs' biogenesis promotes tumor immune escape in bladder cancer, which could bring much more advance to the medical research on tumors.

Abstract
Objective: To evaluate the value of whole exome sequencing (WES) in prenatal clinical application. Methods: A total of 1 152 cases of congenital abnormal [including structural malformation, nuchal translucency (NT) thickening and intrauterine growth restriction] with traditional prenatal diagnosis [including G-band karyotype analysis and chromosome microarray analysis (CMA)] negative were analyzed. The congenital abnormal fetuses were divided into retrospective group and prospective group according to the time of WES detection, that is whether the pregnancy termination or not. According to the specific location of fetal malformation and their family history, the cohort was divided into subgroups. The clinical prognosis of all fetuses were followed up, and the effect of WES test results on pregnancy decision-making and clinical intervention were analyzed. According to the follow-up results, the data of fetuses with new phenotypes in the third trimester or after birth were re-analyzed. Results: Among 1 152 families who received WES, 5 families were excluded because of nonbiological parents. Among the remaining 1 147 families, 152 fetuses obtained positive diagnosis (13.3%,152/1 147), including 74 fetuses in the retrospective group (16.1%,74/460) and 78 fetuses in the prospective group (11.4%,78/687). In fetuses with negative CMA and G-band karyotype analysis results but new phenotypes in the third trimester or after birth, the positive rate by WES data re-analysis was 4.9% (8/163). A total of 34 (21.3%, 34/160) fetuses were directly affected by the corresponding positive molecular diagnosis. Among 68 cases of live births with diagnostic variation grade 4, 29 cases (42.7%, 29/68) received appropriate medical intervention through rapid review of WES results. Conclusions: WES could increase the detection rate of abnormal fetuses with negative G-banding karyotype analysis and CMA by 13.3%. Prenatal WES could guide pregnancy decision-making and early clinical intervention. It might be an effective strategy to pay attention to the special follow-up of the third trimester and postnatal fetus and to re-analyze the WES data.

Abstract
OBJECTIVE To investigate the value of quantitative detection of ITGA4 and SFRP2 gene methylation in stool DNA for the early diagnosis and prognostic evaluation of colorectal tumors. OBJECTIVE Real-time PCR was used for quantitative assessment of ITGA4 and SFRP2 gene methylation levels in stool samples of 85 patients with colorectal cancer, 65 patients with colorectal adenoma and 40 healthy subjects. OBJECTIVE The 3 groups were comparable for age and gender composition. Methylated ITGA4 and SFRP2 promoters were detected in 48.2% and 62.4% of patients with colorectal cancer, respectively, with a combined positivity of 81.2%. ITGA4 and SFRP2 promoter methylation was detected in 23.1% and 43.1% of patients with colorectal adenoma, respectively, with a combined positivity of 69.2%. The positivity rates of ITGA4 and SFRP2 methylation were significantly higher in patients with colorectal cancer than in those with colorectal adenoma (P < 0.001; P= 0.001) and healthy subjects (P < 0.001; P < 0.001). In colorectal cancer group, ITGA4 and SFRP2 promoter methylation levels were correlated with postoperative tumor recurrence in colorectal cancer group, and the relapse-free survival rate was significantly lower in positive patients for ITGA4 and SFRP2 promoter methylation than in the negative patients (P=0.0002; P=0.007). Multivariate analysis with the COX proportional hazard regression model showed that methylation of ITGA4 and SFRP2 gene promoters (P=0.01) and the degree of tumor differentiation (P=0.03) were associated with the recurrence of colorectal cancer, and were independent risk factors for the recurrence of colorectal cancer. OBJECTIVE Combined detection of ITGA4 and SFRP2 gene methylation levels in stool DNA can improve the early diagnosis rate of colorectal tumor. ITGA4 and SFRP2 promoter methylation and the degree of tumor differentiation are independent risk factors for colorectal cancer recurrence.

Abstract
Objective: To understand the status of tobacco use and related influencing factors in population in Shandong province. Methods: Stratified multi-stage cluster sampling was used to select respondents from 216 villages (communities) of 36 districts (counties) in Shandong province. Influencing factors on smoking were analyzed by logistic regression model. Results: The adequate sample size was 6 271 participants. After complex weighted, the current smoking prevalence was 23.93%,45.58% in males and 1.18% in females. The Public's smoking rates varied widely among different groups in the population. 45-64 age group had the highest smoking rate (25.07%). Smoking rates were substantially different in education levels, with the highest in junior high school (28.94%). The rate was higher in the rural area (24.98%) than that in the urban areas (23.08%). The average daily smoking rate was 20.23%. The average age of initiating smoking was 21.21 years. The average daily cigarette intake was 16.31 cigarettes. Among all the former and current smokers, the quitting rate was 20.79%. Multiple logistic regression model analysis showed that gender, age, occupation, region, and health knowledge score were correlated with smoking behavior. The current smoking rate of men was much higher than that of women (OR=49.625, 95%CI: 37.832-65.093). The current smoking rate in 45-64 age group was higher than that in the 15-24 age group (OR=1.830, 95%CI: 1.048-3.194). The current smoking rate of medical (OR=0.403, 95%CI: 0.187-0.866) and retired personnel (OR=0.648, 95%CI: 0.481-0.873) were lower than those engaging in agriculture, forestry, animal husbandry and the fishery ,respectively. The prevalence of residents living in the central part showed lower rate on current smoking than that in the eastern region (OR=0.724, 95%CI: 0.606-0.865). The current smoking prevalence of smoke hazard in 1-3 score group was higher than that in the group with 4-6 score (OR=1.432, 95%CI: 1.240-1.654). Conclusions: Smoking rate in adults in Shandong remained stable and at a high level. Comprehensive intervention measures such as tobacco control and health education should be carried out to reduce the smoking rate.

Abstract
Climate warming could exacerbate the occurrence of thaw settlement hazard in the permafrost regions of the Qinghai-Tibet Plateau (QTP), which would threaten the stability of engineering infrastructure in cold regions. The risk associated with permafrost settlement, valuable for the regional sustainable development, remains poorly assessed or understood on the QTP. In this study, three common Geo-hazard indices were used to assess the settlement risks in the permafrost regions of the QTP, including the settlement index, the risk zonation index, and the allowable bearing capacity index. However, large spatial differences existed in simulating the risk maps by using the abovementioned Geo-hazard indices. Hence, we developed a combined index (Ic) by integrating the three indices to reduce the uncertainty of the simulations. The results indicated that the ground ice is a critical factor for assessing the settlement risk in permafrost regions. We also applied the Ic to assess the settlement risk along the Qinghai-Tibet Railway (QTR). The proportion of low-risk area along the QTR would be the highest (45.38%) for the future periods 2061-2080 under Representative Concentration Pathway 4.5. The medium-risk area combined with the high-risk area would be accounted for more than 40%, which were located at the boundary of the present permafrost regions. Therefore, the corresponding adaptation measures should be taken to reduce the potential economic losses caused by the high-risk regions to the infrastructure. Overall, the results would present valuable references for engineering design, construction and maintenance, and provide insights for early warning and prevention of permafrost thaw settlement hazard on the QTP.

Abstract
OBJECTIVE To determine the effect of miR-217 on the apoptosis of atherosclerotic endothelial cells (AECs) through the Toll-like receptor (TLR) 4/PI3K/Akt/NF-κB pathway. MATERIALS AND METHODS Oxidized low-density lipoprotein (ox-LDL) was used to construct an atherosclerotic endothelial cell model, and the expression of miR-217/TLR4/PI3K/Akt/NF-κB in the cells was regulated to explore their effects on the viability, apoptosis, inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-6 (IL-6), and interleukin-10 (IL-10)], and endothelial-to-mesenchymal transformation (EndMT) of the endothelial cells. RESULTS In AECs, miR-217 expression decreased, and the PI3K/Akt/NF-κB pathway was inhibited. The Dual-Luciferase reporter assay revealed that TLR4 was the target of miR-217, and it was up-regulated in AECs, and the further study revealed that up-regulation of miR-217 protected AECs, increased their activity, reduced their apoptosis, and inhibited inflammatory response and EndMT, while TLR4 acted contrary to miR-217. Besides, it was also found that miR-217 inhibited the PI3K/Akt/NF-κB pathway, thus weakening the influence of si-TLR4 on endothelial cells. Furthermore, miR-217 inhibited EndMT by inhibiting TLR4 from activating the PI3K/Akt/NF-κB signal pathway. CONCLUSIONS In AECs, TLR4 expression increased, and miR-217 and the PI3K/Akt/NF-κB signaling pathway are inhibited. Additionally, miR-217 can increase the viability of AECs through the TLR4/PI3K/Akt/ NF-κB signal transduction pathway, and inhibit their apoptosis, inflammatory response, and EndMT.

Abstract
Background:Systemic lupus erythematosus (SLE) is an autoimmune disease, the immune system of patients to be disordered, especially in T cell subsets1. They were prone to mental diseases, anxiety particularly, which lead to suicide2. The recent study had reported that CD4+ T cells in the peripheral blood played the key role in like anxiety behavior of mice3. Although there showed that the level of serum TNF-α in SLE patients with anxiety was higher than without anxiety4, finding the important special mediators especially in T cell subsets was still necessary for the prevention of anxiety in SLE patients.Objectives:In total, 108 SLE patients, which met the diagnostic criteria of the American Society of rheumatology (v1997), were enrolled in this study from Affilliated Hospital of Nantong University, China. Exclusion criteria included other autoimmune diseases and active infection (including hepatitis B or C virus, Epstein-Barr virus, human immunodeficiency virus or Mycobacterium tuberculosis infection).Methods:We surveyed the abundance of 74 immune cell subpopulations from 108 SLE patients using flow cytometry, and investigated their differences between patients with and without anxiety (24 versus 84). Moreover, machine learning including Lasso regression, Random forest (RF) and Sparsity partial least squares discriminant analysis (sPLS-DA) was employed to build models and futher selected important features for the classification of SLE patients with anxiety.Results:SLE patients with anxiety showed higher body mass index (BMI) and lower quality of life. In their peripheral blood, the proportion of internal cell subsets composition of Th cell and Treg cells changed. By machine learning, we finally found that BMI and PD1-CD28- Treg played important rules to developing lupus anxiety.Conclusion:In this study, machine learning was applied to build models to select the most important T cell subset in SLE patients with anxiety. These findings suggested that BMI and imbalance of PD1-CD28- Treg containing effector memory Treg cells and effector Treg cells mostly played important roles in the development of SLE anxiety.Disclosure of Interests:None declared

Abstract
PURPOSE OF THE REVIEW The human gut harbors a complex community of microbes that influence many processes regulating musculoskeletal development and homeostasis. This review gives an update on the current knowledge surrounding the impact of the gut microbiota on musculoskeletal health, with an emphasis on research conducted over the last three years. RECENT FINDINGS The gut microbiota and their metabolites are associated with sarcopenia, osteoporosis, osteoarthritis, and rheumatoid arthritis. The field is moving fast from describing simple correlations to pursue establishing causation through clinical trials. The gut microbiota and their microbial-synthesized metabolites hold promise for offering new potential alternatives for the prevention and treatment of musculoskeletal diseases given its malleability and response to environmental stimuli.

Abstract
The long non-coding RNA (lncRNA) imatinib-upregulated (IUR) has been recently reported as a tumor suppressor in leukemia. Preliminary microarray data revealed a downregulation of IUR in pancreatic adenocarcinoma (PAAD) and a positive correlation with microRNA-34a (miR-34a) expression. The present study aimed to investigate the role of IUR in PAAD. This study included samples from 58 patients with PAAD and the PAAD cell lines Capan-2 and HPAC. Reverse transcription quantitative PCR was performed to determine gene expression levels. Cell transfections were carried out to assess gene interactions between IUR, miR-34a and CD44. Transwell assays were performed to explore the effects of transfections on cell invasive and migratory abilities. The results demonstrated that IUR was downregulated in PAAD tissue compared with adjacent non-tumor tissue samples and that low expression levels of IUR correlated with poor survival in patients with PAAD. In PAAD tissue samples, the expression of IUR positively correlated with miR-34a expression but negatively correlated with CD44 expression, which is a target of miR-34a. In PAAD cells, overexpression of IUR resulted in miR-34a upregulation and CD44 downregulation. miR-34a overexpression did not affect the expression of IUR but downregulated CD44. In PAAD cells, overexpression of IUR and miR-34a led to decreased invasive and migratory abilities. However, CD44 overexpression played an opposite role and attenuated the effects of IUR and miR-34a overexpression. In conclusion, the results from this study demonstrated that IUR may upregulate miR-34a expression in order to inhibit PAAD cell migration and invasion by downregulating CD44.

Abstract
BACKGROUND Lymph node metastasis (LNM) in gastric cancer is a prognostic factor and has implications for the extent of lymph node dissection. The lymphatic drainage of the stomach involves multiple nodal stations with different risks of metastases. The aim of this study was to develop a deep learning system for predicting LNMs in multiple nodal stations based on preoperative CT images in patients with gastric cancer. METHODS Preoperative CT images from patients who underwent gastrectomy with lymph node dissection at two medical centres were analysed retrospectively. Using a discovery patient cohort, a system of deep convolutional neural networks was developed to predict pathologically confirmed LNMs at 11 regional nodal stations. To gain understanding about the networks' prediction ability, gradient-weighted class activation mapping for visualization was assessed. The performance was tested in an external cohort of patients by analysis of area under the receiver operating characteristic (ROC) curves (AUC), sensitivity and specificity. RESULTS The discovery and external cohorts included 1172 and 527 patients respectively. The deep learning system demonstrated excellent prediction accuracy in the external validation cohort, with a median AUC of 0·876 (range 0·856-0·893), sensitivity of 0·743 (0·551-0·859) and specificity of 0·936 (0·672-0·966) for 11 nodal stations. The imaging models substantially outperformed clinicopathological variables for predicting LNMs (median AUC 0·652, range 0·571-0·763). By visualizing nearly 19 000 subnetworks, imaging features related to intratumoral heterogeneity and the invasive front were found to be most useful for predicting LNMs. CONCLUSION A deep learning system for the prediction of LNMs was developed based on preoperative CT images of gastric cancer. The models require further validation but may be used to inform prognosis and guide individualized surgical treatment.

Abstract
BACKGROUND Solanesol is an important pharmaceutical intermediate raw material, mainly used to synthesize coenzyme Q10, vitamin K2. It can be found prominent in potato stems and leaves. But now potato stems and leaves are always abandoned or discarded as they are not suitable for use as feed in aquaculture or other purposes. These agricultural waste resources can be reutilized as the corresponding extracts. OBJECTIVE To develop a simple and standardized method for the detection of total solanesol in potato leaves and its extracts. METHODS N-hexane was chosen as the extraction solvent for three times in the solanesol extraction from potato leaves. HPLC-MS was used for the detection. RESULTS The LOQ was 0.3 µg/g and the linear range was from 0.1 to 50 µg/mL. The precision and stability were evaluated by the relative standard deviations (RSDs) of three samples (potato leaves, Extract-1, Extract-2) for interday and intraday. The accuracy of the method was evaluated by the recoveries of three different spiked concentrations of solanesol for three samples, and results showed it ranged from 80.7% to 99.0% with RSDs less than 8.7%. CONCLUSIONS The method we established can provide a simple and standardized way for the extraction and detection of total solanesol. HIGHLIGHTS The work laid a foundation for the resource reutilization of potato stem and leaf.

Abstract
OBJECTIVE To investigate the role of hepatocyte mitochondrial NDUFA13 loss in the liver fibrogenesis in mice and explore the possible mechanisms. OBJECTIVE We used liver-specific NDUFA13 heterozygous knockout mouse models (NDUFA13fl/-; Alb-Cre) established previously by intercrossing NDUFA13fl/fl and Alb-Cre mice, with their littermate control NDUFA13fl/fl mice as the control (n=8). The mice were euthanized at the age of 4 weeks and 2 years, and the liver tissues were collected for HE and Masson staining to observe the pathological changes and fibrosis phenotypes. Western blotting was performed to detect the expression of NDUFA13 protein in the liver tissues, and the infiltration of F4/80+ macrophages and the expressions of TGF-β1, TNF-α and IL-1β were analyzed by immunofluorescence assay. The expression levels of α-SMA, matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteases 1 (TIMP-1), collagen-Ⅰ and collagen-Ⅲ were assayed by immunohistochemistry. OBJECTIVE HE and Masson staining showed obvious inflammatory infiltration but no significant fibrosis in the liver tissues of 4-week-old NDUFA13fl/- mice, but severe liver damage with massive fibrosis was observed in 2-year-old NDUFA13fl/- mice. NDUFA13 expression in 2-year-old NDUFA13fl/- mice markedly decreased compared with that in the control NDUFA13fl/fl mice as shown by Western blotting (P < 0.05). Immunohistochemistry showed obvious infiltration of F4/80+ macrophages in the liver tissue with a large amount of TGF-β1 production (P < 0.05) and TNF-α and IL-1β secretions in NDUFA13fl/- mice (P < 0.05). NDUFA13 knockout obviously promoted α-SMA expression (P < 0.05) and collagen-Ⅰ and collagen-Ⅲ deposition (P < 0.05) while significantly decreased MMP-9 and increased TIMP-1 expression in the liver (P < 0.05). OBJECTIVE Hepatocytes-specific NDUFA13 deficiency can trigger spontaneous and chronic liver fibrosis phenotypes in mice probably in association with abnormal activation of hepatic stellate cells induced by macrophages and inflammatory factors.

Abstract
OBJECTIVE MicroRNA-325 (miR-325) is a tumor suppressor in some cancers. However, the role of miR-325 in determining the chemosensitivity to cancer cells is still not clear. The aim of this study was to investigate the effect of miR-325 on reversing the cisplatin resistance of bladder cancer. MATERIALS AND METHODS Cisplatin-resistant 5637 and T24 bladder cancer cell lines (5637/R and T24/R) were established through long term exposure of them to cisplatin. 3-(4,5-dimethylthiazol-2-yl)-2,5- diphenyltetrazolium bromide (MTT) assays were performed to evaluate the viability of 5637, 5637/R, T24, and T24/R cells. Quantitative Real-Time Polymerase Chain Reaction (qRT-PCR) was used to examine the expression of miR-325 in these cell lines. The regulatory mechanism was confirmed by Western blot analysis and Luciferase reporter assays. After treatment with miR-325 and cisplatin, mitochondrial membrane potential (MMP) and apoptosis were measured using flow cytometry. Expression of hematopoietic cell-specific protein 1-associated protein X-1 (HAX-1) and activation of caspase-9, caspase-7, and caspase-3 were detected by Western blotting. RESULTS We found the downregulation of miR-325 in 5637/R and T24/R cells compared to their parental 5637 and T24 cells. Moreover, overexpression of miR-325 in cisplatin-resistant bladder cancer cells was found to increase the cytotoxicity of cisplatin to them. However, transfection with HAX-1 plasmid can abolish the effect of miR-325 on cisplatin. We, then, showed that overexpression of miR-325 suppressed the expression of HAX-1. Thus, miR-325 promoted the mitochondria collapse and cisplatin-induced apoptosis in bladder cancer cells. CONCLUSIONS Downregulation of miR-325 is responsible for the development of cisplatin resistance in bladder cancer. Overexpression of miR-325 may represent a novel strategy to reverse the chemoresistance of bladder cancer.

Abstract
OBJECTIVE Diabetic nephropathy (DN), the microvascular complications of diabetes, is one of the world's public health hazard. But the detailed mechanism of the occurrence and development remains unclear. Oxidative stress caused by multiple factors is recognized as the main cause of disease, and it is also a research focus. Recently, long non-coding RNAs (lncRNAs) have been declared to involve in a large of important bioactivities in many different diseases. In our study, we aimed to verify whether lncRNA PAX8-AS1-N involved in protecting podocyte apoptosis and directly associated with VEGF/TGF-β1/8-OhdG levels in DN, and further investigated the detailed mechanism that PAX8-AS1-N regulated the pathological process. MATERIALS AND METHODS We used blood and urine samples of DN patients to detect the expression of lncRNA-PAX8-AS1-N and VEGF/TGF-β1/8-OhdG by ELISA and quantitative reverse transcription polymerase chain reaction (qRT-PCR). Albuminuria level, relative PAX8-AS1-N and VEGF/TGF-β1/8-OhdG levels, and VEGF/TGF-β1/8-OhdG and cleaved-caspase-3 protein levels were detected by ELISA, qRT-PCR, and Western blot, respectively. CCK8 assay was used to measure the proliferation ability of conditionally immortalized mouse podocytes (MPC5). And we used the TUNEL assay to detect MPC5 apoptosis. Luciferase reporter assay was used to confirm the direct target of PAX8-AS-N and miR-17-5p in MPC5. RESULTS We found that the lncRNA PAX8-AS1-N was lowly expressed and high expression of VEGF/TGF-β1/8-OhdG and high level of albuminuria in DN patients and high-glucose-treated MPC5. Besides, we proved that LV-PAX8-AS1-N decreased MPC5 apoptosis and suppressed the expression of VEGF/TGF-β1/8-OhdG in vitro experiment. At last, the overexpression of miR-17-5p markedly induced cell apoptosis in MPC5 with high glucose (HG) model. STAT3 reverses the effects of miR-17-5p overexpression in MPC5 with HG model. CONCLUSIONS Above that, we found that lncRNA PAX8-AS1-N/miR-17-5p/STAT3 axis was closely related the progression of DN, which could be a potential target for treating DN patients.

Abstract
Objective: To develop and validate the health-related quality of life (HRQOL) questionnaire for adult patients with anisometropic amblyopia. Methods: Cross-sectional study. A total of 170 adult patients with anisometropic amblyopia, 100 adult patients with other eye diseases and 80 healthy adults with normal vision were recruited at the First Affiliated Hospital of Nanjing Medical University, and 20 healthy adults with normal vision were recruited at Qinhuai Medical District of Easter Theater General Hospital of PLA from December 2019 to February 2020. Individual interviews of 30 adult patients with anisometropic amblyopia generated 80 questionnaire items. For item reduction, 40 adult patients with anisometropic amblyopia were asked to complete the 80-item questionnaire and responses were analyzed. Then factor analyses were performed to identify prominent factors (subscales). The reliability of the questionnaire was evaluated by Cronbach's α coefficient. The overall and sub-scale scores were the average scores of all included items, ranging from 0 (worst HRQOL) to 100 (best HRQOL). The final 20-item questionnaire was administered to additional 100 adult patients with anisometropic amblyopia, 100 adult patients with other eye diseases and 100 visually normal adults. Mean overall and subscale scores were compared across groups using one-way analysis of variance. Results: The final adult anisometropic amblyopia questionnaire (AAAQ) consisted of a function subscale and a psychosocial subscale, each containing 10 items. The Cronbach's α coefficients of the overall, function subscale and psychosocial subscale were 0.88, 0.78 and 0.78. There were 55 males and 45 females in 100 adult anisometropic amblyopia patients, with a median age of 26 years (range, 18 to 43 years). The age and gender distribution were matched with 100 adult patients with other eye diseases and 100 healthy adults with normal vision (all P>0.05). The mean overall score (28.63±9.18), function subscale score (27.69±9.88) and psychosocial subscale score (29.53±9.90) for adult patients with anisometropic amblyopia were significantly lower compared to adult patients with other eye diseases (71.28±8.14, P<0.01; 65.56±7.81, P<0.01; 76.85±10.76, P<0.01) and visually normal adults (84.54±9.13, P<0.01; 81.70±9.27, P<0.01; 87.38±10.06, P<0.01). Conclusion: The AAAQ meets the requirements for validity and reliability of a HRQOL questionnaire, and can be used to assess the HRQOL of adult patients with anisometropic amblyopia.

Abstract
Free radicals play a vital role in all kinds of biological processes including immune responses. However, free radicals have short lifetimes and are highly reactive, making them difficult to measure using current methods. Here, we demonstrate that relaxometry measurement, or T1, inherited from the field of diamond magnetometry can be used to detect free radicals in living cells with subcellular resolution. This quantum sensing technique is based on defects in diamond, which convert a magnetic signal into an optical signal, allowing nanoscale magnetic resonance measurements. We functionalized fluorescent nanodiamonds (FNDs) to target single mitochondria within macrophage cells to detect the metabolic activity. In addition, we performed measurements on single isolated mitochondria. We were able to detect free radicals generated by individual mitochondria in either living cells or isolated mitochondria after stimulation or inhibition.

Abstract
Muscle fibers are closely related to human diseases and livestock meat quality. However, the genetics basis of microRNAs (miRNAs) in regulating muscle fibers is not completely understood. In this study, we constructed the whole genome-wide miRNA expression profiles of porcine fast-twitch muscle [biceps femoris (Bf)] and slow-twitch muscle [soleus (Sol)], and identified hundreds of miRNAs, including four skeletal muscle-highly expressed miRNAs, ssc-miR-378, ssc-let-7f, ssc-miR-26a, and ssc-miR-27b-3p. Moreover, we identified 63 differentially expressed (DE) miRNAs between biceps femoris vs. soleus, which are the key candidate miRNAs regulating the skeletal muscle fiber types. In addition, we found that the expression of DE ssc-miR-499-5p was significantly correlated to the expression of Myoglobin (r = 0.6872, P < 0.0001) and Myosin heavy chain 7 (MYH7; r = 0.5408, P = 0.0020), and pH45 min (r = 0.3806, P = 0.0380) and glucose content (r = -0.4382, P = 0.0154); while the expression of DE ssc-miR-499-3p was significantly correlated to the expression of Myoglobin (r = 0.5340, P = 0.0024) and pH45 min (r = 0.4857, P = 0.0065). Taken together, our data established a sound foundation for further studies on the regulatory mechanisms of miRNAs in skeletal muscle fiber conversion and meat quality traits in livestock, and could provide a genetic explanation of the role of miRNAs in human muscular diseases.

Abstract
Objective: To explore the effects of environmental, genetic factors as well as the interactions in early life on the short-term and long-term health of offspring and to systematically evaluate the pregnancy outcomes and health of offspring after birth between families with assisted reproductive technology (ART) conception and families with spontaneous conception. Methods: The China National Birth Cohort (CNBC), a multicenter prospective birth cohort study, includes both families with ART conception and families with spontaneous conception. Since 2016, CNBC has recruited families from 24 hospitals located in 12 provinces, municipalities and autonomous regions throughout China. Information and biospecimens were collected before ART treatment, embryo transfer, at early, second, third trimester and delivery, and at 42 days, 6, 12 and 36 months after birth. Results: By June 2020, CNBC had included 27 044 families with ART conception and 29 589 families with spontaneous conception. The majority of the participants are urban residents. Among the families with ART conception, 65.5% of the men and 63.7% of the women had college degrees or higher. The mean age distribution of men and women was (33.83±5.52) and (32.38±4.67) years. 83.2% of women were primiparas, and the prevalence rates of current regular smokers and current alcohol drinkers were 0.8% and 2.1% in women. Among the families with spontaneous conception, 81.5% of the men and 86.5% of the women had college degrees or higher. The mean age distribution of men and women was (32.06±5.09) and (30.40±4.27) years. 67.2% of women were primiparas, and the prevalence rates of current regular smokers and current alcohol drinkers were 0.1% and 2.2% in women. The baseline characteristics were different between the families with ART conception and spontaneous conception in different regions. Conclusion: CNBC provides a powerful and rich resource in studying the impact of genetic, environmental factors and interactions in early life and ART treatment on the health of offspring after birth.

Abstract
With the rapid changes in lifestyle, natural and social environment, the reproductive health status of couples in childbearing age continues to decline, and long-term outcomes of the rapidly increasing offspring conceived by assisted reproductive technology (ART) needs to be evaluated urgently. Therefore, the focus of research now needs to be extended from death and severe diseases to full life cycle and full disease spectrum. In order to meet the demand for such research, we launched the China National Birth Cohort (CNBC) study, an ongoing prospective and longitudinal study aiming to recruit 30 000 families underwent ART and 30 000 families with spontaneous pregnancies. Long-term follow-up programs will be conducted for both spouses and their offspring. Data of couples and their offspring, such as environmental exposure, reproductive history, psychological and behavioral status, will be collected during follow-up. Peripheral blood, urine, umbilical blood, follicular fluid, semen were also collected at different follow-up nodes. Based on high-quality data and biological samples, CNBC will play an extremely important supporting role and have a far-reaching impact on maternal and children's health care and reproductive health in China. This paper is exactly a brief introduction to the construction and basic design of CNBC.

Abstract
Muntjac deer (Cervidae: Muntiacus) are often cited as an excellent model for the study of vertebrate evolution due to their fast rate of change in chromosome number among vertebrates. However, the phylogenetic relationships within Muntiacus generally, and the taxonomic status of Muntiacus gongshanensis specifically, remain unclear. Here, the phylogenetic relationships within Muntiacus were studied using mitochondrial genome (mitogenome) and cytochrome b (cyt b) segments. Our results recognize 12 species within Muntiacus and support the controversial species M. gongshanensis, M. putaoensis, and M. malabaricus. Furthermore, Bayesian inference (BI) and maximum-likelihood (ML) approaches revealed M. gongshanensis and M. crinifrons to be closely related species, with M. feae as their sister species, and M. putaoensis and M. truongsonensis to be closely related, with M. rooseveltorum as their sister species. The distribution range of M. gongshanensis was also confirmed in southwest China (Namdapha, Modong, Zayu and Gongshan) and northern Myanmar (Putao). The results of this study provide insight into the evolution of Muntiacus and further provide a molecular basis for the taxonomic evaluation of the genus in the future and fundamental data for the conservation of M. gongshanensis.

Abstract
The specific ammonia uptake rates (SAUR) and ammonia oxidizing bacteria (AOB) community of influent sewage and activated sludge in the 2nd wastewater treatment plant (WWTP) of Xi'an without the primary settling tank were analyzed over multiple years to explore the seasonal effects of the influent AOB on the activated sludge systems. During the experiment, the SAUR of the raw sewage and activated sludge were 0.48-3.02 mg·(g·h)-1 and 0.68-2.25 mg·(g·h)-1, respectively. Meanwhile, the correlation analysis indicated that the monthly SAUR of the raw sewage was highly correlated with that of the activated sludge of the following month (r=0.862,P<0.05), which indicated that influent nitrifiers had a significant effect on the nitrification performance of activated sludge. Considering that the estimated AOB seeding intensities based on the ammonia oxidizing activity were 0.21-0.92 g·(g·d)-1, the nitrifier immigration from the raw sewage should added to the design of WWTP and the activated sludge modeling. Moreover, the qPCR results revealed that the AOB abundance of activated sludge in winter decreased but remained at 1010 cells·g-1, indicating that the immigration of influent nitrifiers could partially compensate for the reduction of the AOB abundance in the activated sludge caused by decreasing temperatures. Finally, the Illumina MiSeq sequencing demonstrated that the shared dominant AOB between the raw sewage and activated sludge were Nitrosomonas sp. Nm58, Nitrosomonas sp. JL21, and bacterium CYCU-0253. These findings can provide theoretical support for the design and operation of a WWTP.

Abstract
One of the most cited limitations of biochemical detection is its poor sensitivity, owing to the relatively high complexity of micro-samples. Moreover, some samples cannot be easily self-replicated and their abundance cannot be increased through traditional technologies. Therefore, the preconcentration of low-abundance samples is a key requirement for microfluidic biological analysis. In recent years, the ion-concentration polarization phenomenon has aroused widespread interest in the application of microfluidic technology. In addition, paper-based materials are readily available, easy to modify, and exhibit good hydrophilicity. The study of the ion-concentration polarization preconcentration of micro-samples in paper-based microfluidic chips is of considerable significance. In this review, we discuss the development and applications of ion-concentration polarization paper-based preconcentrator in the past 5 years, with emphasis on key progresses in chip fabrication and performance optimization under different conditions. The current needs and development prospects in this field have also been discussed.

Abstract
Sublethal effect considered as an emerging factor to assess the environmental risk of insecticides, which can impact the insects on both physiology and behavior. Lethal exposure can be causing near immediate mortality. Pests are inevitably exposed to sublethal and lethal dose in the agroecosystem following application of pesticides. Insecticides, widely used for the control of insect pests, are irreplaceable in insect pest management. The effects of imidacloprid by the method of high-throughput non-targeted metabolomics was investigated in Aphis gossypii Glover exposed to LC10 and LC90 doses of the imidacloprid, and the control group was treated with the same condition without imidacloprid. Pairwise comparisons showed that 111 metabolites changed significantly, 60 in the LC10 group, and 66 in the LC90 group compared to the control group, while only 16 changes in the LC10 were same with that in LC90 group. Among the changed metabolites, a total of 16 metabolites were identified as potential biomarkers, which represented the most influential pathways including glycolysis and gluconeogenesis, alanine, aspartate, and glutamate metabolism, ascorbate and aldarate metabolism, glutathione metabolism, phenylalanine metabolism, tyrosine metabolism, caffeine metabolism and parkinson's disease (PD), which could account for the sublethal and lethal effects on A. gossypii. These modified metabolic pathways demonstrated that high energy consumption, excitotoxicity and oxidative stress (OS) were appeared in both LC10 and LC90 groups, while PD was detected only in the LC90 group. The results of non-targeted metabolomics revealed the effects of neonicotinoid pesticide exposure on A. gossypii successfully, and provided a deep insight into the influenced physiology by the stress of neonicotinoid pesticide in the insect.

Abstract
Titanium (Ti) and Ti alloys are widely used biomaterials, but they lack osteogenic capability for rapid bone integration. To improve osseointegration of Ti implants, TiO2 nanotubes were prepared using the anodizing oxidation technique, and strontium (Sr) combined with icariin (ICA) was loaded on TiO2 nanotube coatings. Cell adhesion and proliferation of MC3T3-E1 cells, alkaline phosphatase (ALP) activity, mineralization of extracellular matrix, and bone formation around titanium implants in ovariectomized rats, were examined separately. The results showed that compared with pure Ti, TiO2 and Sr-loaded TiO2 coatings, the coatings loaded with both Sr and ICA showed better effect on cell adhesion and proliferation, higher ALP activity and more red-stained mineralized nodules. Furthermore, more bone was formed around implants loaded with both Sr and ICA in osteoporotic rats. Therefore, coating with Sr and ICA is valuable for clinical application to strengthen the osseointegration of titanium implants, especially in osteoporotic patients.

Abstract
Objective: To analyze the three-dimensional distribution of functional sinus node, right phrenic nerve and superior vena cava(SVC)-right atrial muscle sleeves by three-dimensional electrophysiological technique in patients with atrial fibrillation (AF), and to investigate the efficacy and safety of segmental radiofrequency catheter ablation (RFCA) for isolation of superior vena cava in these patients. Methods: In this retrospective study, we enrolled 136 AF patients who underwent first RFCA in the First Affiliated Hospital of Zhengzhou University from July 2018 to June 2019 and all patients underwent SVC isolation under sinus rhythm. Baseline clinical data of patients were collected. The functional sinus node was defined by activation mapping, pacing was guided by three-dimensional mapping (Carto) system, localization of the right phrenic nerve was defined by pacing map, the superior vena cava-right atrial muscle sleeves was determined according to the change of potential during SVC isolation, segmental RFCA was performed for SVC isolation, the three-dimensional distribution of functional sinus node, right phrenic nerve and superior vena cava(SVC)-right atrial muscle sleeves was determined by three-dimensional electrophysiological technique. Immediate SVC isolation was achieved in all patients. Patients were evaluated immediately after RFCA and patients were followed at 3, 6, 9, and 12 months after RFCA. Holter monitoring was performed every 3 months, the chest radiograph and the SVC ultrasonic examination were performed every 6 months after RFCA. Postoperative complications were assessed. Results: The mean age of the 136 patients with AF was (51.6±14.2) years, 86 (63.2%) were male, 98 cases (72.1%) were paroxysmal AF and 38 cases (27.9%) were persistent AF. Right atrium activation mapping revealed that 17 (12.5%) functional sinus node were located in the SVC, 78 (57.4%) were located at the SVC-right atrium junctions, 41 (30.1%) were located below the junction level. From the head to foot view, 83 (61.0%) functional sinus node were located at the anterior lateral segment of the SVC-right atrium three-dimensional reconstruction model, 34 (25.0%) located at the posterior lateral segment, 15 (11.0%) located at the anterior wall, 4 (2.9%) located at posterior wall or anterior septum. A total of 294 SVC muscle sleeves were detected among all patients, 94 (32.0%) SVC muscle sleeves were located at the anterior septum of the SVC-right atrium three-dimensional reconstruction model, 76 (25.9%) were located at the posterior septum, 21(7.1%) were located at the posterior free wall, 11 (3.7%) were located at the posterior lateral, 27 (9.2%) were located at anterior lateral wall and 65 (22.1%) were located at the anterior free wall. Right phrenic nerve positioned relatively fix, 133 (97.8%) were located at the lateral segment of the SVC-right atrium three-dimensional reconstruction model, 3 (2.2%) were located at the anterior free wall. Sinus rhythm and SVC isolation were successfully restored immediately after RFCA, no significant SVC stenosis, right phrenic nerve palsy and functional sinus node injury occurred immediately post procedure. All patients were followed up for (11.2±3.6) months and none had postoperative complication. Conclusions: Three-dimensional electrophysiological can determine the spatial location of functional sinus node, right phrenic nerve and SVC-right atrial sleeves. On this basis, segmental RFCA is a safe and effective method to achieve complete isolation of SVC.

Abstract
Objective: To investigate the effect of a novel laparoscopic W-H fundoplication in the treatment of proton pump inhibitor (PPI) dependent gastroesophageal reflux disease (GERD). Methods: The clinical data of PPI dependent GERD patients who underwent laparoscopic W-H fundoplication in PLA Rocket Force Characteristic Medical Center from October 1st, 2018 to April 30th, 2019 were analyzed retrospectively. The GERD symptom score, subjective symptom relief, PPI withdrawal, efficacy satisfaction and postoperative complications were followed up and analyzed by a questionnaire. Results: A total of 80 GERD patients were included in this study, and 49 were male and 31 were female, with a median age of 58 years. Among all patients, 85% (68/80) are with esophagitis and 77.5% (62/80) with hiatal hernia. The operation time was 67 (52, 73) minutes, without intraoperative complications and conversion to laparotomy. The postoperative follow-up period was 16 (14, 18) months. The postoperative GERD symptom scores were significantly lower than those before surgery, with an statistical difference (all P<0.05). The subjective remission degree of the overall digestive and respiratory symptoms were 100 (90, 100)% and 100 (80, 100)%, respectively. During the follow-up period, the PPI discontinuation rate was 83% (69/80), and the satisfactory rate was 93% (75/80). Postoperative complications included dysphagia, flatulence, increased exhaust and diarrhea, and the incidence was 61% (49/80), 8% (6/80), 5% (4/80) and 4% (3/80), respectively, and 16% (13/80) of the patients had prolonged occasional mild dysphagia. There was no death, symptomatic recurrence or reoperation. Conclusions: The novel W-H fundoplication has a good medium-term efficacy, with significant GERD symptom control rate and PPI discontinuation rate. The postoperative dysphagia is common, but it is self-limiting and does not affect the satisfaction of the surgical effect.

Abstract
The adaptive immunity that protects patients from coronavirus disease 2019 (COVID-19), caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), is not well characterized. In particular, the asymptomatic patients have been found to induce weak and transient SARS-CoV-2 antibody responses, but the underlying mechanisms remain unknown; meanwhile, the protective immunity that guide the recovery of these asymptomatic patients is elusive. Here, we characterized SARS-CoV-2-specific B-cell and T-cell responses in 10 asymptomatic patients and 64 patients with other disease severity (mild, n = 10, moderate, n = 32, severe, n = 12) and found that asymptomatic or mild symptomatic patients failed to mount virus-specific germinal center (GC) B cell responses that result in robust and prolonged humoral immunity, assessed by GC response indicators including follicular helper T (TFH) cell and memory B cell responses as well as serum CXCL13 levels. Alternatively, these patients mounted potent virus-specific TH1 and CD8+ T cell responses. In sharp contrast, patients of moderate or severe disease induced vigorous virus-specific GC B cell responses and associated TFH responses; however, the virus-specific TH1 and CD8+ T cells were minimally induced in these patients. These results, therefore, uncovered the protective immunity in asymptomatic patients and also revealed the strikingly dichotomous and incomplete humoral and cellular immune responses in COVID-19 patients with different disease severity, providing important insights into rational design of effective COVID-19 vaccines.

Abstract
The pathogenicity of Metarhizium rileyi is a multi-faceted process that depends on many factors. This study attempts to decipher those factors of M. rileyi by investigating its pathogenicity against Spodoptera litura (Lepidoptera: Noctuidae) larvae. Through morphogenesis analysis, we for the first time demonstrated the infection structure, appressorium, of M. rileyi that can generate a more than 4 MPa turgor pressure. The Mrpmk1 gene was found to be essential for appressorium differentiation and mycelium reemerging, ΔMrpmk1 mutant exhibited no pathogenicity towards S. litura by natural infection process. Delayed appressorium formation time, decreased appressorium formation rate and turgor pressure of ΔMrpbs2 mutant manifested itself in postponed death time and lower mortality against S. litura. Following invasion into the larval hemocoel, M. rileyi cells transformed into blastospores, which may be conducive to dispersal and propagation, moreover, the blastospore form M. rileyi may subverted phagocytic defenses. Then M. rileyi cells morphed into extended hyphal body to cope with elongated hemocytes that participated in encapsulation. In the end, M. rileyi mycelia reemerged from the larval cadaver evenly to form muscardine cadaver. Eventually, conidia were produced to complete the infection cycle. During the infection, M. rileyi triggered both cellular and humoral immunity of S. litura. Besides morphological changes, stage-specifically produced oxalic acid and F-actin arrangement may play roles in nutrient acquisition and mycelium reemerging, respectively.

Abstract
BACKGROUND A pulmonary arteriovenous fistula (PAVF) is a rare condition that is associated with pulmonary arteriovenous malformation (PAVM). Few reports have described managing PAVMs using uniportal video-assisted thoracoscopic surgery (VATS). CASE PRESENTATION A 13-year-old child with PAVF in the left inferior pulmonary artery was treated by uniportal VATS with left lower lobectomy. After surgery, hemoptysis did not recur and there were no postoperative complications. Six months after the operation, postoperative review of computerized tomography showed no recrudescence of PAVF. CONCLUSIONS PAVF is a rare case that should be diagnosed and treated early. 3D- computerized tomography (CT) reconstruction is useful for diagnosis and preoperative assessment. The case shows that PAVF can be managed with uniportal VATS.

Abstract
AIM To explore the presence and function of NLRP6-caspase 4 inflammasome in human pulp tissue and human dental pulp cells (HDPCs). METHODOLOGY Pulp tissue was collected from freshly extracted human caries-free third molars and third molars with irreversible pulpitis. Quantitative real-time polymerase chain reaction (qRT-PCR) and western blot were performed to assess the expression of NLRP6-caspase 4 inflammasome. HDPCs were prepared from normal human pulp tissues and challenged with Porphyromonas gingivalis LPS. Enzyme-linked immunosorbent assay (ELISA) and qRT-PCR were performed to assess if LPS can upregulate NLRP6 and caspase-4. HDPCs were further challenged with LPS followed with cytosolic Streptococcus mutans lipoteichoic acid (LTA). SiRNA targeting NLRP6 and Casp4 and pharmacology inhibitor Ac-FLTD-CMK and MCC950 were used to assess if Streptococcus mutans LTA can activate the NLRP6 but not the NLRP3 inflammasome. Western blot and ELISA were performed to evaluate inflammasome activation. The Student's t-test and one-way anova were used for statistical analysis. RESULTS NLRP6-caspase 4 inflammasome was upregulated and activated in inflamed human dental pulp tissue. In HDPCs, Porphyromonas gingivalis LPS upregulated the expression of NLRP6, CASP1 and CASP4 in a type I interferon dependent manner. After LPS priming, cytosolic Streptococcus mutans LTA triggered NLRP6-caspase 4 inflammasome activation. Knockdown of NLRP6 or CASP4 using siRNA or using pharmacology inhibitor Ac-FLTD-CMK but not MCC950 efficiently suppressed inflammasome activation by cytosolic LTA. CONCLUSIONS NLRP6-caspase 4 inflammasome may play an important role in pulp inflammation and immune defence. Inflammatory caspases represent a pharmacological target to restrain pulpal inflammation.
