Abstract
CONTEXT Nanoparticle albumin-bound paclitaxel (Nab-PTX) is a form of paclitaxel bound to albumin nanoparticles and is used widely in a neoadjuvant setting for patients with breast cancer. AIMS We conducted a retrospective study to compare the efficacy and safety of Nab-PTX to PTX as neoadjuvant chemotherapy for patients with operable HER2-negative breast cancer. SETTINGS AND DESIGN In total, 50 patients were enrolled. Nab-PTX was administered in the study group, and PTX was administered in the control group. SUBJECTS AND METHODS The clinical response and safety profile were recorded. The expression of secreted protein acidic rich in cysteine (SPARC) in tumor tissue was examined. STATISTICAL ANALYSIS The efficacy and safety analyses were computed using SPSS statistical software. Multiple logistic regression analysis was performed to evaluate the exploratory variables (age, stage, estrogen receptor, partial response, and SPARC expression) for the pathological complete response (pCR), and Fisher's exact test was performed to evaluate the relationship between SPARC and pCR. RESULTS Both groups of patients achieved a good clinical response. The pCR rate for the Nab-PTX regimen was significantly higher than that for the PTX regimen. The most common adverse events were neutropenia, peripheral sensory neuropathy, arthralgia, and myalgia. In 68% of cases in the Nab-PTX group, high SPARC expression was observed. CONCLUSIONS As neoadjuvant therapy, the Nab-PTX regimen has advantages over conventional taxane regimen in patients with HER2-negative breast cancer. With this regimen, a high pCR rate was achieved with a good safety profile.

Abstract
Goats are one of the most widespread farmed animals across the world; however, their migration route to East Asia and local evolutionary history remain poorly understood. Here, we sequenced 27 ancient Chinese goat genomes dating from the Late Neolithic period to the Iron Age. We found close genetic affinities between ancient and modern Chinese goats, demonstrating their genetic continuity. We found that Chinese goats originated from the eastern regions around the Fertile Crescent, and we estimated that the ancestors of Chinese goats diverged from this population in the Chalcolithic period. Modern Chinese goats were divided into a northern and a southern group, coinciding with the most prominent climatic division in China, and two genes related to hair follicle development, FGF5 and EDA2R, were highly divergent between these populations. We identified a likely causal de novo deletion near FGF5 in northern Chinese goats that increased to high frequency over time, whereas EDA2R harbored standing variation dating to the Neolithic. Our findings add to our understanding of the genetic composition and local evolutionary process of Chinese goats.

Abstract
OBJECTIVE To explore the specific role of ILK (integrin-linked kinase) in regulating renal fibrosis and its underlying mechanism. MATERIALS AND METHODS NRK-52E cells were induced by transforming growth factor-β1 (TGF-β1) for observing phenotype change. Renal tubular epithelial cell marker, fibrosis marker and expression level of ILK in NRK-52E cells were also detected. After overexpression of ILK, phenotype change of NRK-52E cells was observed. For in vivo experiments, we constructed UUO (unilateral ureteral obstruction) model in CD1 mice. Renal tubular epithelial cell marker, fibrosis marker and expression level of ILK in UUO mice were detected. The regulatory effect of ILK on renal fibrosis was detected after injection of ILK overexpression plasmid. Western blot was performed to detect related genes in the TGF-β1/smad pathway. RESULTS Accompanied by the TGF-β1-induced phenotype change in NRK-52E cells, both mRNA and protein levels of ILK were upregulated. Overexpression of ILK remarkably stimulated the phenotype change in NRK-52E cells. Similarly, ILK was highly expressed in UUO mice. Renal fibrosis was aggravated after injection of ILK overexpression plasmid in UUO mice. Western blot results showed that expressions of p-smad3 and smad3 were upregulated during the process of renal fibrosis. CONCLUSIONS ILK is upregulated during the process of renal fibrosis. ILK participates in the development of renal fibrosis by altering phenotypes of renal tubular epithelial cells via a TGF-β1/smad pathway.

Abstract
Objective: To study the pathological changes of the spleen in patients with COVID-19 and to analyze the relationship between the weakened immune system and splenic lesions. Methods: Postmortem needle autopsies from the spleen were carried out on 10 patients who died from COVID-19 in Wuhan. Routine hematoxylin and eosin (HE) staining was used to observe the pathological changes. The changes of lymphocytes were studied further with immunohistochemistry.RT-PCR was used to detect 2019-nCoV RNA in the spleen. In addition,the Epstein-Barr virus (EBV) was detected by in situ hybridization, and coronavirus particles were detected by transmission electron microscopy in 2 cases. Results: There were 7 males and 3 females, with an average age of 68.3 years.Of the 10 cases, 4 had cancer history and another 4 had other underlying diseases respectively.Cough, fever, malaise and dyspnea were the main clinical symptoms.The time from onset to death was 15-45 days.Ten cases patients had normal or slight increase in peripheral blood leukocyte count in the early stage of the disease, 6 cases had significant increase before death. Five patients' peripheral blood lymphocyte count decreased in the early stage of the disease, and 10 patients' peripheral blood lymphocyte count decreased significantly before the disease progressed or died. Seven cases were treated with corticosteroid (methylprednisolone ≤40 mg/d, not more than 5 days). Histopathological examination showed that the cell composition of the spleen decreased, white pulp atrophied at different levels, meanwhile lymphoid follicles decreased or absent;in addition, the ratio of red pulp to white pulp increased with varying degrees. In 7 cases, more neutrophil infiltration was found, and in 5 cases, scattered plasma cell infiltration was found. Macrophage proliferation and hemophagocytic phenomena in a few cells were found in a case. Meanwhile, necrosis and lymphocyte apoptosis were detected in 2 cases, small artery thrombosis and spleen infarction in 1 case, and fungal infection in 1 case. The results of immunohistochemistry showed that the T and B lymphocyte components of the spleen in all cases decreased in varying degrees. CD20(+) B cells were found to accumulate in the lymphoid sheath around the splenic artery in 8 cases. However, CD20 and CD21 immunostaining in 2 cases showed that the number of white pulp was almost normal, and splenic nodules were atrophic. CD3(+), CD4(+) and CD8(+)T cells were decreased. In 9 cases,CD68(+) macrophages were no significant changes in the distribution and quantity. While more CD68(+) cells were found in the medullary sinuses of 1 case (related to fungal infection). Few CD56(+) cells were found. EBV was negative by in situ hybridization. RT-PCR was used to detect the nucleic acid of 2019-nCoV. One of 10 cases was positive, 39 years old,who was the youngest patient in this group, and the other 9 cases were negative. Coronavirus particles were found in the cytoplasm of macrophage under electron microscope in 2 cases. Conclusions: The death of COVID-19 occurs mainly in the elderly, and some cases have no underlying diseases. Spleen may be one of the organs directly attacked by the virus in some patients who died from COVID-19. T and B lymphocyte in the spleen decrease in varying degrees, lymphoid follicles are atrophied, decreased or absent, and the number of NK cells do not change significantly. And the pathological changes of the spleen are not related to the use of low dose corticosteroid, which may be related to the direct attack of virus and the attack of immune system on its own tissues.

Abstract
Background:Abnormal liver function can be seen in not only hepatitis B virus infection (HBV), hepatitis C virus infection (HCV), hepatic carcinoma (HCC), but also in primary biliary cirrhosis (PBC), autoimmune hepatitis (AIH), and systemic autoimmune rheumatic diseases (SARD). Antinuclear antibody (ANA) testing using indirect immunofluorescence assay (IIFA) is a common and economical method which contributes to detect SARD and autoimmune liver diseases [1].Objectives:Our objective was to investigate ANA positivity, titers and their patterns in multiple liver diseases, including PBC, AIH, HBV, HCV, and HCC, compared to healthy controls (HC).Methods:2537 patients with SARD, 137 PBC cases, 57 AIH cases, 3420 HBV cases, 769 HCV cases, 268 HCC cases, and 1073 HC were retrospectively assessed. The titers and patterns of ANA were detected with the IIFA method.Results:ANA positivity rate was considerably discernible between these diseases, which is 90.1% in SARD, 93.4% in PBC, 49.1% in AIH, 19.1% in HBV, 13.9% in HCV and 23.5% in HCC. Moreover, only 4.9% of HCC cases, 2.5% of HBV patients and 1.6% of HCV patients had an ANA titer ≥ 1:320. The mixed pattern which composed of at least two patterns majorly lied in PBC. AC-15 and AC-21 was frequently related to liver diseases; the former pattern was more frequently found in AIH (84.2%) and PBC (8.8%), and the latter pattern was easily seen in PBC (62.2%) and HCC (22.6%). The positive rate of ANA in HC was 12.2% and its major pattern was AC-2.Conclusion:There are differences in ANA positivity among patients with SARD and various liver diseases. Some mixed patterns may provide important evidence for the diagnosis of PBC. Clinicians should pay attention to ANA patterns and titer during the interpretation of this test.References:[1]Damoiseaux J, Andrade L, Carballo OG, Conrad K, Francescantonio P, Fritzler MJ, Garcia DLTI, Herold M, Klotz W, Cruvinel WM, Mimori T, von Muhlen C, Satoh M, Chan EK, (2019) Clinical relevance of HEp-2 indirect immunofluorescent patterns: the International Consensus on ANA patterns (ICAP) perspective.

Abstract
Background:Circular RNAs (circRNAs) participate in the initiation and progression of various diseases by miRNA sponges including postmenopausal osteoporosis[1], bladder cancer[2], and osteoarthritis (OA)[3]. However, the activity of circRNAs as “miRNA sponges” in rheumatoid arthritis (RA) has not been studied.Objectives:To investigate whether circRNA acts as competing endogenous RNA to regulate pathological processes of RA, and whether the N6-methyladenosine (m6A) modification affects Circ_0088194 stability in RA fibroblast-like synoviocytes (RA-FLSs).Methods:CircRNA microarray analysis was conducted to characterize the expression profiles of circRNAs in 3 RA-FLSs and 3 osteoarthritis fibroblast-like synoviocytes (OA-FLSs). Methylated RNA immunoprecipitation was performed to validate the level of m6A modification on Circ_0088194 in RA-FLSs and OA-FLSs. Dual-luciferase reporter assay, bioinformatics analysis, protein array analysis, and fluorescence in situ hybridization were employed to evaluate the interaction between Circ_0088194 and miR-766-3p, and between target miR-766-3p and matrix metalloproteinase 2 (MMP2).Results:Overexpression of Circ_0088194 promoted the migration and invasion of RA-FLSs and increased MMP2 expression. The expression and function of miR-766-3p were inversely correlated with Circ_0088194, which sponged miR-766-3p to upregulate MMP2 expression. Although m6A modification of Circ_0088194 exists in RA-FLSs and OA-FLSs, their level did not differ.Conclusion:This study presents an important role of this novel circRNA as a sponge of miR-766-3p to promote RA-FLS migration and invasion by targeting MMP2. However, the modification might not affect Circ_0088194 stability in RA-FLSs and OA-FLSs. Therefore, Circ_0088194 may contribute to RA development and represent as an auspicious therapeutic target.References:[1]Yu, L., and Liu, Y.

Abstract
Background:Rheumatoid arthritis (RA) is a chronic, debilitating autoimmune disease and is associated with high direct medical costs. Treatment of RA with disease-modifying anti-rheumatic drugs (DMARDs) can improve patients’ health-related quality of life (HRQOL) and has the potential to reduce direct medical costs associated with RA. Treatment with janus kinase inhibitors, such as upadacitinib (UPA), has shown improvements in HRQOL in patients with RA [1].Objectives:To estimate the economic benefit from improvements in HRQOL and to compare estimated direct medical costs between: (1) UPA and tofacitinib (TOFA) and (2) UPA monotherapy and methotrexate (MTX) monotherapy in patients with RA.Methods:This economic analysis used individual patient-level data from 2 randomized clinical trials (RCTs) of UPA (SELECT-NEXT and SELECT-MONO) and published aggregate data from 1 RCT of TOFA (ORAL-Standard) in patients with moderate to severe RA that collected repeated measurements of HRQOL based on the Short Form 36 Health Survey (SF-36). Estimated direct medical costs per patient per month (PPPM) for UPA 15mg once daily (QD) and MTX were estimated based on observed SF-36 Physical (PCS) and Mental Component Summary (MCS) scores in the SELECT RCTs using a published regression algorithm [2]. Direct medical costs PPPM for TOFA 5mg twice daily (BID) were estimated from Rendas-Baum, et al [3], which applied the same regression algorithm to SF-36 PCS and MCS scores observed in the ORAL-Standard RCT. Resulting estimates of direct medical costs PPPM in the short-term (12–14 weeks) and long-term (48 weeks) were compared between UPA and TOFA and between UPA and MTX. Costs were inflation-adjusted to 2018 US dollars. Bootstrapping was used to generate 95% confidence intervals (CI).Results:Over 12 weeks, estimated direct medical costs PPPM were $186 lower (95% CI: $21, $364) in patients treated with UPA compared with those treated with TOFA. Estimated long-term medical costs PPPM at Weeks 24 and 48 (Figure 1) and cumulative costs over the entire 48-week period (difference: $1,452; 95% CI: $906, $2,086; Table) were significantly lower for UPA than for TOFA. Over 14 weeks, estimated direct medical costs PPPM were $370 lower (95% CI: $147, $575) in patients treated with UPA monotherapy compared with those treated with MTX alone. Estimated long-term direct medical costs at Week 48 (Figure 2) and cumulative costs over the entire 48-week period (difference: $2,120; 95% CI: $1,398, $2,861; Table) were significantly lower for UPA monotherapy compared with MTX alone.Conclusion:Based on improvements in HRQOL in the short-term and long-term, UPA 15mg QD was associated with significantly lower direct medical costs than TOFA 5mg BID in patients with active RA. UPA 15mg QD monotherapy was associated with significantly lower direct medical costs than MTX monotherapy in patients with active RA. These results provide evidence of the economic benefits of UPA as a novel treatment for moderate to severe RA.References:[1]Strand V, et al.Arthritis Res Ther2019;21:272;[2]Fleishman JA, et al.Med Care2006;44(Suppl 5):I54–63;[3]Rendas-Baum R, et al.Rheumatology2017;56:1386–94.Table.Cumulative cost savings over 48 weeks with UPA vs TOFA and UPA vs MTXTreatmentTotal 48-week medical costs ($)Difference (95% CI)UPA vs TOFATOFA 5mg BID8,9641,452 (906, 2,086)UPA 15mg QD7,511—UPA vs MTXMTX9,8332,120 (1,398, 2,861)UPA 15mg QD7,713—Acknowledgments:Financial support for the study was provided by AbbVie.

Abstract
Background:Poorer work productivity due to pain and functional impairment is commonly seen in ankylosing spondylitis (AS) patients, which may contribute to huge social economic burden. However, data about work outcomes and associated factors in Chinese AS patients were barely reported.Objectives:To assess work outcomes and identify factors associated with poor work productivity in patients with AS in China.Methods:A cross-sectional study was conducted in China. Adult patients (aged ≥ 18 years) fulfilled the 1984 New York modified criteria of AS were enrolled from rheumatology center from Jan 2017 to Aug 2017. All participants completed questionnaires about socio-demographic characteristics, disease characteristics, quality of life and the Work productivity and activity impairment questionnaire in AS (WPAI:SpA) to accesses the impact of chronic health conditions on job performance and productivity. Factors associated with work outcomes were evaluated.Results:A total of 91 patients with AS were included: 87.8% males, 78.02% employed, mean age and disease duration of 30 and 10 years respectively. The mean (SD) activity impairment of all patients was 48.57% (22.02%). For patients with employed work, mean (SD) absenteeism, presenteeism and work productivity loss were 10.22% (19.44%), 43.86% (22.48%) and 47.92% (25.81%) respectively. In multivariable analysis, activity impairment was associated with Bath Ankylosing Spondylitis Functional Index (BASFI) (P<0.01) and Ankylosing Spondylitis Quality of Life (ASQoL) (P<0.01). Absenteeism was associated with disease duration (P=0.03). Presenteeism was associated with disease duration (P=0.04), BASFI (P<0.01) and ASQoL (P<0.01). Work productivity loss was associated with BASFI (P<0.01) and ASQoL (P<0.01).Conclusion:Longer disease duration, reduced physical function and poorer quality of life are associated with reduced work productivity in Chinese AS patients.References:[1]Boonen A, van der Heijde D, Landewe R, Spoorenberg A, Schouten H, Rutten-van Molken M, et al.

Abstract
Background:Photoacoustic imaging (PAI), a new imaging technique which can be integrating with ultrasound (US) imaging, has shown potential in visualizing small joints. We have developed a multimodal photoacoustic/ultrasound (PA/US) imaging system, equipped with a handheld probe, which can provide dual-wavelength PA/US imaging to identify the micro-vessels of the inflamed articular regions and measure the oxygenation level of human inflamed synovium.Objectives:To validate the potential value for RA of the imaging system.Methods:A total of 32 RA patients received PA/US examination on seven small joints (MCP2, MCP3, PIP2, PIP3, MTP2, MTP5, and wrist of the clinically dominant side). The 0-3 score was used to semi-quantify the PA and PD signals of the inflammatory articular lesions, and the sums of PA and PD scores (PA-sum and PD-sum) were utilized. The relative oxygen saturation (SO2) values of the inflamed regions were measured by calculating the ratio of PA signals at the wavelength of 750nm and 830nm. All the patients were classified to 3 PA+SO2 patterns (Pattern 1: no or minimal PA signals; Pattern 2: evident PA signals and hyperoxia; Pattern 3: evident PA signals and hypoxia). The correlations between imaging scores and laboratory data, as well as clinical scoring systems were assessed.Results:A total of 32 patients of RA were recruited aged from 25-71 years-old were examined. PD-sum had moderate correlation with the clinical scores (r=0.529, 0.546, 0.490, 0.493 for DAS28ESR, DAS28CRP, SDAI, CDAI), moderate correlations with TJC (r=0.575) and SJC (r=0.491), fair correlation with VAS (r=0.239), poor correlation with PGA (r=0.153), and moderate correlation with EGA (r=0.457). The PA-sum had substantial correlations with the clinical scores (r= 0.699, 0.746, 0.723, 0.736 for DAS28ESR, DAS28CRP, SDAI, CDAI), substantial correlations with TJC (r=0.787) and SJC (r=0.694), moderate correlations with VAS (r=0.544) and PGA (r=0.529), and substantial correlation with EGA (r=0.708).Ten patients were classified as Pattern 1, 12 as Pattern 2, 9 as Pattern 3. The PA+ SO2 patterns presented substantial correlations with the clinical scores (DAS28ESR r=0.690, DAS28CRP r=0.782, SDAI r=0.805, CDAI r=0.799, SJC r=647, TJC r=0.676, respectively), substantial correlation with VAS (r=0.714), and moderate correlation with PGA (r=0.476) and EGA (r=0.502). Significant differences between those who were classified as hypoxia and hyperoxia with evident PA signals, were detected in VAS (p=0.020) and PGA (p=0.026).Conclusion:The PA-sum scores and the PA+SO2 patterns can be utilized as objective imaging parameters reflecting the disease activity of RA. PAI may serve as a supplement to conventional US examinations for RA patients.References:[1]Backhaus, M., et al., Evaluation of a novel 7-joint ultrasound score in daily rheumatologic practice: a pilot project.

Abstract
Background:Studies into ankylosing spondylitis (AS) and its relationship with immune function are controversial, and the correlation between the efficacy of TNF-α inhibitor and changes in immune function is unclear.Objectives:We conducted a prospective study of T-cell and B-cell subset distribution and analyzed lymphocyte function in AS patients to further clarify changes to the immune system caused by AS and to explore resistance that could contribute to relapse after treatment.Methods:A total of 40 immune cells were tested with flow cytometry, and the results of 105 HC (healthy control) subjects, 177 active-stage AS patients, and 23 AS cases before and after 12 weeks of Anbainuo therapy were analyzed.Results:Compared with the HC group, the proportion of immune cells, such as naïve and central memory CD4+T cells, in AS increased (p<0.0001), but effector memory and terminally differentiated CD4+T cells were decreased (p<0.01 and 0.0001, respectively). Naïve, central memory, and effector memory CD8+T cells were increased (p<0.0001, 0.001, and 0.01, respectively), but terminally differentiated CD8+T cells were decreased (p<0.0001). Th1 cells (helper T cells-1), Tfh1 cells (follicular helper T cells-1), Tc1 cells (cytotoxic T cells-1), and Tregs (regulatory T cells) were lower (p<0.01, 0.05, 0.0001, and 0.001, respectively), but Th17 cells, Tfh17 cells, and Tc cells were higher (p<0.001, 0.0001 and 0.001, respectively). The proportions of total B cells and class-switched B cells were increased (p<0.05), but non-switched B cells, plasma cells, memory B cells, and immature Bregs (regulatory B cells) were lower (p<0.01, 0.0001, 0.0001, and 0.0001, respectively). After Anbainuo therapy, the percentage of Tregs and B10 cells (IL-10-producing regulatory B cells) had increased (p<0.01and 0.05, respectively), and the increase in Tregs was positively correlated with the decrease in CRP (C-reactive protein) (r= 0.489, p=0.018).Conclusion:We found that, in terms of both innate and acquired immunity, active-stage AS patients have an immunity imbalance involving multiple types of immune cells, including CD4+T cells, CD8+T cells, Th cells, Tfh cells, Tc cells, Tregs, Bregs, and B cells. Anbainuo can not only help to inhibit disease activity and partial immune function imbalance in AS but can also increase the number of negative regulatory cells in inflammation.References:[1]Long, S., et al., High frequency of circulating follicular helper T cells is correlated with B cell subtypes in patients with ankylosing spondylitis.

Abstract
Purpose: Translating the Neck Disability Index (NDI) into the Malay language (NDI-M); evaluation of psychometric properties in patients with neck pain.Methods: The NDI-M was translated according to established guidelines. In the first visit, 120 participants completed the NDI-M, visual analogue scale (VAS) for pain and demographic details. 98 participants returned to complete similar questionnaires and the Global Rating of Change (GRoC) scale. The NDI-M was evaluated for internal consistency, test-retest reliability, content validity, construct validity and responsiveness.Results: The NDI-M demonstrated excellent internal consistency (Cronbach's α = 0.84) and good test-retest reliability (ICC2,1 = 0.79). Content validity was confirmed with no floor or ceiling effects. Construct validity was established revealing three-factor subscales explaining 68% of the total variance. The NDI-M showed a moderate correlation with VAS (Rp = 0.49, p < 0.001). Regarding responsiveness, a moderate correlation between NDI-M change scores and VAS change scores was found (Rp = 0.40, p < 0.001). However, there was no significant correlation between NDI-M with GRoC (Rs = 0.11, p = 0.27).Conclusions: The NDI-M is a reliable and valid tool to measure functional outcomes in patients with neck pain. It is responsive in detecting changes in pain intensity during a patient's rehabilitation journey.Implications for rehabilitationThe NDI was translated into the Malay language and culturally adapted for Malay-speaking patients with neck pain.The NDI-M demonstrated an excellent level of internal consistency and good test-retest reliability. It demonstrated content and construct validity, with three-factor subscales, and moderate responsiveness for pain intensity.The NDI-M is a reliable, valid and responsive instrument to measure functional limitations in patients with neck pain for rehabilitation.

Abstract
OBJECTIVES Undetectable or low-level hepatitis B virus (HBV) DNA and drug resistance mutations in patients may increase the risk of HBV transmission or cause active viral replication and other clinical problems. Here, we established a highly sensitive and practical method for HBV and drug resistance detection using a polymerase chain reaction (PCR) -based CRISPR-Cas13a detection system (referred to as PCR-CRISPR) and evaluated its detection capability using clinical samples. METHODS Specific CRISPR RNAs (crRNAs) are designed for HBV DNA detection and YMDD (tyrosine-methionine-aspartate-aspartate) variant identification. The HBV DNA was detected in 312 serum samples for HBV diagnosis using quantification PCR (qPCR) and PCR-CRISPR. Additionally, 424 serum samples for YMDD testing were detected by qPCR, direct sequencing, and our assay. RESULTS Using PCR-CRISPR, one copy per test of HBV DNA was detected with HBV-1 crRNA in 15 min after PCR amplification. Consistent results with qPCR were observed for 302 samples, while the remaining 10 samples with low-level HBV DNA were detectable by PCR-CRISPR and droplet digital PCR but not by qPCR. PCR-CRISPR diagnosed all 412 drug-resistant samples detected by the YMDD detection qPCR kit and direct sequencing, as well as the other 12 drug-resistant samples with low-level HBV DNA undetectable by qPCR and direct sequencing. CONCLUSIONS We developed a novel PCR-CRISPR method for highly sensitive and specific detection of HBV DNA and drug resistance mutations. One copy per test for HBV DNA and YMDD drug resistance mutations could be detected. This method has wide application prospects for the early detection of HBV infection, drug resistance monitoring and treatment guidance.

Abstract
WHAT IS KNOWN AND OBJECTIVE Antituberculosis drug-induced liver injury (ATLI) is a serious adverse drug reaction, and its pathogenic mechanism is still largely unknown. Rifampin (RIF) has been reported to cause haemolysis due to the production of drug-dependent antibodies, and haemolysis results in an increased level of free haem, which affects the function of hepatocytes. Blood group determinants can act as specific receptor sites for drug-antibody complexes, causing erythrocyte destruction in the presence of RIF. RIF-induced immune haemolysis may be a potential mechanism for ATLI. Thus, the study aimed to explore the role of ABO blood group systems in Chinese ATLI patients. METHODS A 1:4 matched case-control study was conducted among 146 ATLI cases and 584 controls. Multivariable conditional logistic regression and Cox proportional regression were used to estimate the association between ABO blood group and risk of ATLI by odds ratio (OR), hazards ratio (HR) and 95% confidence intervals (CIs), and liver disease history and taking hepatoprotectant were used as covariates. RESULTS AND DISCUSSION Patients in the A, B, AB and non-O blood groups had a significantly higher risk of ATLI than those in the O blood group (OR = 1.832, 95% CI: 1.126-2.983, P = .015; OR = 1.751, 95% CI: 1.044-2.937, P = .034; OR = 2.059, 95% CI: 1.077-3.938, P = .029; OR = 1.822, 95% CI: 1.173-2.831, P = .007, respectively). After considering the time of ALTI occurrence, similar results were found in the A, B, AB and non-O blood groups (HR = 1.676, 95% CI: 1.072-2.620, P = .024; HR = 1.620, 95% CI: 1.016-2.584, P = .043; HR = 2.010, 95% CI: 1.130-3.576, P = .018; HR = 1.701, 95% CI: 1.138-2.542, P = .010, respectively). Furthermore, subgroup analysis also detected a significant association between ABO blood group and ATLI in patients taking RIF (P < .05). However, no significant difference was observed in patients not taking RIF (P > .05). WHAT IS NEW AND CONCLUSION The present study is the first to evaluate the role of ABO blood group systems in Chinese ATLI cases. Based on the present matched case-control study, the ABO blood group may be associated with susceptibility to ATLI in the Chinese antituberculosis population, especially in patients with blood groups A, B and AB who are taking RIF.

Abstract
Objective: To observe the number of blood vessels and the anatomical characteristics of the anterior ciliary vessels (ACVs) in the horizontal rectus muscles of patients with concomitant horizontal strabismus. Methods: Cross-sectional study. From July 2016 to September 2019 patients with concomitant horizontal strabismus treated by realignment surgeries in Xiamen Eye Center of Xiamen University were included. Patients who had previous operations on eyes were excluded. The high resolution surgical imaging of ACVs in the horizontal rectus muscles was performed during operation. The photos of ACVs in muscles were tagged and observed to compare the distribution of the various numbers of blood vessels and morphological characteristics of the ACVs in the medial and lateral rectus muscles. In addition, muscle tissues about 4 mm with an intact sheath were gained from patients undergoing the muscle resection. The muscle sections were stained with hematoxylin-eosin staining, and the arteriovenous properties and their distribution in muscles and fascia tissues were observed. The chi-square test was used for statistical analysis. Results: A total of 387 patients with concomitant horizontal strabismus (176 with esotropia, 211 with exotropia) were enrolled in this study, among whom 198 were male and 189 were female. The age ranged from 1 to 68 years (median, 13 years). Photos of ACVs in 742 horizontal rectus muscles from 383 patients were observed. Of the 351 medial rectus muscles, 24 (6.8%) contained 1 major (or bundle of) ACV, 163 (46.4%) contained 2 major (or bundles of) ACVs, and 164 (46.7%) contained 3 or more major (or bundles of) ACVs. Of the 391 lateral rectus muscles, 161 (41.2%) contained 1 major (or bundle of) ACV, 156 (39.9%) contained 2 major (or bundles of) ACVs, and 74 (18.9%) contained 3 or more major (or bundles of) ACVs. The distribution of ACVs in the medial and lateral rectus muscles was statistically different (χ(2)=133.87, P<0.01). According to the number and morphological characteristics of vessels, the ACVs in the medial and lateral rectus muscles were divided into 4 and 3 categories, respectively, as well as various types and subtypes. The rate of patients whose both eyes had the same type of ACVs in the medial or lateral rectus muscles was 31.6% (25/79) and 26.1% (29/111), respectively, and there was no significant difference (χ(2)=0.69, P=0.41). However, the ACVs of the same type from both eyes of the same patient were not identical in morphology. The ACVs in the medial and lateral rectus muscles with collateral circulation accounted for 3.7% (13/351) and 24.3% (95/391), respectively, and the difference was statistically significant (χ(2)=63.07, P<0.01). The hematoxylin-eosin staining of the medial lateral rectus tissues from 4 patients showed that the ACVs contained arteries and veins. The vessels in the medial rectus muscles were distributed in muscle tissue and fascia tissue, while the vessels in the lateral rectus muscles were only distributed in fascia tissue. Conclusions: Compared with the lateral rectus muscles, there are about 50% medial rectus muscles contain more than 3 major (or bundles of) vessels in patients with concomitant horizontal strabismus. The accompanying patterns of arteries and veins of ACVs are varied. ACVs are distributed in muscle tissue of the medial rectus muscles and in fascia tissue of the medial and lateral rectus muscles.

Abstract
OBJECTIVE Increasing evidence has shown that HSF1 is involved in glycemia regulation, and SIRPα plays a pivotal role in islet β-cell viability. However, it is still unknown whether SIRPα is associated with HSF1 in regulating the cell viability and cell death of islet β-cells. MATERIALS AND METHODS Western blot and qPCR were applied to determine protein and mRNA levels of HSF1 and SIRPα. Cell viability and death were investigated by cell counting kit-8 and trypan blue exclusion assay. Meanwhile, cell apoptosis was analyzed by detecting caspase3 activity. Moreover, luciferase reporter assay was applied to explore the mechanism by which HSF1 transcriptionally upregulated SIRPα expression. RESULTS Our study reveals that HSF1 expression was lower in islets from T1DM compared to normal mice. We found that overexpression of HSF1 decreased the apoptosis of islet β-cell lines. Moreover, we demonstrated that overexpression of HSF1 decreased the apoptosis of islet β-cells through increasing the expression of SIRPα. In terms of mechanism, luciferase reporter assays showed that HSF1 upregulated SIRPα expression by activating its gene promoter region. The binding site (-1809 to -1795) was required for HSF1-induced increase of SIRPα gene promoter activity. CONCLUSIONS These results indicate that the low expression of HSF1/SIRPα may be one of the mechanisms of islet β-cell death and targeting HSF1/SIRPα may be a novel strategy for the treatment of T1DM.

Abstract
Objective: To systematically evaluate the quality of gastric cancer screening guidelines/recommendations, and provide a reference for the update of gastric cancer screening guidelines/recommendations in China. Methods: "guidelines/consensus/specifications/standards" , "stomach/gastric tumors" , "screening/diagnosis" , "guideline/recommendation" , "gastric cancer/gastric tumor," "early detection of cancer/screening" were searched as keywords in PubMed, Embase, Web of knowledge, China Knowledge Network, Wanfang, China Biomedical Literature Database, and Cochrane Library, as well as the US Preventive Services Working Group, the American Cancer Society, the International Agency for Research on Cancer, the Australia Cancer Council and the International Guide Collaboration Network at the end of July 2018. The inclusion criteria were independent guidelines/recommendation documents for gastric cancer screening. The exclusion criteria were guideline abstracts, interpretation and evaluation literature, duplicate publications, updated original guidelines, and clinical treatment or practice guidelines for gastric cancer. The language was limited to Chinese and English. The European Guide to Research and Evaluation Tools (AGREE Ⅱ) and Practice Guideline Reporting Standard (RIGHT) for Gastric Cancer Screening Guidelines/Recommendations were used to compare and evaluate the quality and reporting standard of gastric cancer screening guidelines/recommendations. Results: A total of five guides/recommendations were included. The results of the AGREE Ⅱ quality evaluation showed that the overall quality of five guides/recommendations was different, including one recommended for "A", one for "B", and three for "C". Each guide/recommendation scored higher in the scope and purpose, clarity, and scores were more significant in the areas of rigor and independence. In the participants, the application field scores were generally low. The RIGHT evaluation results showed that the quality of five guides/recommendations should be improved. The six items with poor report quality were background, evidence, recommendations, review and quality assurance, funding and conflict of interest statement and management, and other aspects. Conclusion: The quality of the included gastric cancer screening guidelines/recommendations is generally low, and the standardization should be strengthened.

Abstract
Myostatin (MSTN) is mostly expressed in skeletal muscle and plays crucial roles in the negative regulation of muscle mass development. The methylation and demethylation of myogenesis-specific genes are major regulatory factors in muscle satellite cell differentiation. The present study was designed to investigate the mechanism of myogenic differentiation regulated by MSTN mutation (MT) and the methylation/demethylation state of downstream genes. The results showed that, in the MSTN-/+ satellite cells, a higher myotube fusion index and a larger myotube length were observed compared to the wild type controls; the genes associated with myogenesis were all up-regulated compared to the WT controls. The methylation of the promoters and gene bodies of PAX3, PAX7, MyoD, and MyoG were all down-regulated, while the expression of the key demethylase TET1 was significantly promoted. ChIP-qPCR was used to demonstrate that the SMAD2/SMAD3 complex combined with the promoter of TET1 to inhibit the activity of TET1 promoter, indicating that MSTN may regulate TET1 via SMAD2/SMAD3. The overexpression of TET1 in wild type cells promoted myogenic differentiation, increased the myotube index, and reduced the methylation of the associated genes. On the contrary, the knockdown of TET1 in the MSTN mutant cells resulted in the opposite phenomena as in the overexpressed cells. In conclusion, the myostatin mutant showed an increased transcriptional activity of TET1, inducing higher levels of demethylation and improving the transcriptional activity levels of myogenic differentiation-associated genes. The binding of SMAD2/SMAD3 directly to the TET1 promoter region indicated that the MSTN mutant demethylated the myogenesis-specific genes by up-regulating TET1, which is directly controlled by SMAD2/SMAD3.

Abstract
Objective: To evaluate the classification of the types of pediatric posterior fossa brain tumors based on routine MRI (T(1)WI, T(2)WI and ADC) using wavelet transformation analysis of whole tumor. Methods: MRI images of medulloblastoma (n=59), ependymoma (n=13) and pilocytic astrocytoma (n=27) confirmed by pathology before treatments in Children's Hospital of Nanjing Medical University from January 2014 to February 2019 were enrolled in this retrospective study as well as the clinical data of age, gender and symptoms. Registration was performed among the three sequences and wavelet features of ROI were acquired. Afterwards, the top ten features were ranked and trained among groups by using random forest classifier. Finally, the results were compared and analyzed according to the classification. Results: The top ten contribution three sequences and wavelet features of ROI were acquired from the ADC sequence. The random forest classifier achieved 100% accuracy on training data and was validated best accuracy (86.8%) when combined of first and third wavelet features. The sensitivity was 100%, 94.8%, 76.9%, and the specificity was 97.6%, 88.0%, 98.8% respectively. Conclusions: Features based on wavelet transformation of ADC sequence of entire tumor can provide more quantitative information, which could provide help in the differential diagnosis of pediatric posterior fossa brain tumors. The optimum combination to distinguish three pediatric posterior fossa brain tumors is sixth and twelfth wavelet features of ADC sequence.

Abstract
PURPOSE Multiple statin-associated muscle symptoms (SAMS) risk factors usually coexist in a given older diabetic patient, but the association between statin use and physical function in older Asian persons with T2MD remains uncertain. The present study therefore sought to provide insight into this uncertainty through a focused assessment of statin-associated outcomes in Chinese diabetic adults. DESIGN Cross-sectional study. SETTINGS AND PARTICIPANTS The study included 146 participants with T2MD in the Center of Gerontology and Geriatric, West China Hospital. MEASUREMENTS The participants received the comprehensive geriatric assessment (CGA). Statin use and other medical data for each patient were determined via assessment of the inpatient hospital information system. Assessments of physical functions included ADLs, IADLs and the Timed "Up and Go" (TUG) test. Multiple regression analyses were then performed in order to determine the relationship between statin utilization and physical function. RESULTS The average age of these 146 participants (32 women, 21.9%) was 80.00±5.60 years. At enrollment, 78 (53.4%) of the 146 patients were treated with statins. Among the statin users, 48.7% presented with a lack of TUG ability, which was significantly greater than in non-statin users (27.9%). However, the rates of IADL and ADL disabilities did not differ significantly between groups. In a multiple regression analyses, statin use was associated with a three-fold (95% CI 1.06, 9.51) increase in the risk of TUG inability, after adjusted all covariates. CONCLUSIONS There was a significant association between statin use and TUG inability in older Chinese inpatients with diabetes.

Abstract
OBJECTIVES To assess the effectiveness of short-term exercise for treating sarcopenia in hospitalized older patients aged 80 years and over. DESIGN Prospective clinical trial. SETTING A post-acute care unit. PARTICIPANTS Sarcopenic patients aged 80 years or over. INTERVENTIONS The participants were allocated to the intervention group (to receive a mixed exercise program with 10 sessions over two weeks) or the control group (usual care) based on the sequence of admission. OUTCOMES The primary outcome was the improvement in activities of daily living (ADL) estimated by the change in Barthel Index (BI) score from the baseline to the end of the 2-week intervention. The secondary outcomes were the changes in gait speed, handgrip strength, the time "UP and GO" test (TUG) score, and the Short Physical Performance Battery (SPPB) score. RESULTS We included 121 participants (intervention group: n = 62; control group: n = 59). All participants in the intervention group finished all 10 exercise sessions. After the 2-week intervention, patients in the mixed exercise group achieved a significant improvement in ADL compared with their counterparts in the control group (the adjusted mean difference of the change in BI score was 7.8 points, 95% confidence interval (CI) 4.0 to 11.8 points). The mixed exercise program significantly but slightly improved gait speed (adjusted group difference in mean change: 0.06 m/s, 95% CI 0.02 to 0.11 m/s). However, the mixed exercise program did not significantly improve the handgrip strength, SPPB score, or TUG score compared with usual care. CONCLUSION Very old inpatients with sarcopenia can benefit from a mixed exercise program (even as short as two weeks) by improving their ADL and gait speed. However, the long-term effects of exercise on important clinical outcomes need to be further evaluated.

Abstract
This study evaluated the growth performance, immunity, and jejunum morphology of chicks hatched from laying breeder hens given dietary additive supplementation, as well as chicks receiving direct antibiotic supplementation in early life. Hy-line breeder hens were allotted to 2 groups with 3 replicates. A control group (CON) was fed a basal diet, and the treatment group (CCAB) received β-carotene, curcumin, allicin, and sodium butyrate in addition to basal diet for 5 wk. Breeder-hen eggs were collected and hatched. The chicks hatched from the CON group were assigned to 2 treatments: a chick control group (cCON) and a chick treatment group (Cipro) given ciprofloxacin lactate into drinking water; the cCON group, Cipro group, and the chicks hatched from the CCAB group (cCCAB) were fed the same diet for 4 wk. The results demonstrated that there were significant differences between the CON and CCAB groups in the serum levels of IgA, IgG, IgM (triple P < 0.01), lysozyme (P < 0.05), and β-defensin (P < 0.05). The body weights of the cCCAB group's chicks increased at 1, 7, and 28 D of age (P < 0.05, P < 0.05, P < 0.01, respectively), and those of the Cipro group's chicks increased at 7 and 21 D of age (P < 0.01, P < 0.05). The tibial lengths of the cCCAB group's chicks increased at 1, 7, 14, 21, and 28 D of age (P < 0.01, P < 0.05, triple P < 0.01), and the lengths in the Cipro group increased at 7 and 14 D of age (P < 0.01, P < 0.01). Intestinal development, including intestinal length, jejunum morphology, and IgA positive cells, helps to explain these results. The breeder eggs from the CCAB group had higher IgG (P < 0.05) and IgM (P < 0.05) levels in the egg whites and higher IgA, IgG, and IgM levels (triple P < 0.01) in the egg yolks. In conclusion, β-carotene, curcumin, allicin, and sodium butyrate supplementation of laying breeder hen diets produced more advantages in growth performance and intestinal development in offspring than in chicks directly supplemented with antibiotics.

Abstract
OBJECTIVES No pictorial questionnaire is available for screening sarcopenia. We aimed to develop a self-reported cartoon questionnaire based on the SARC-F and the Finger-Ring test and to compare its diagnostic accuracy with the SARC-F and the SARC-F combined with calf circumference (SARC-CalF). DESIGN A diagnostic accuracy study. SETTING Urban communities in Chengdu, China. PARTICIPANTS Older adults aged ≥ 60 years. METHODS We established a multidiscipline team to design this pictorial questionnaire, entitled Self-Reported Cartoon SARC-CalF (cSARC-CalF). We used the Asian Working Group for Sarcopenia (AWGS) criteria as the "gold standard" of sarcopenia. We performed sensitivity/ specificity analyses of the three tools (cSARC-CalF, SARC-CalF, and SARC-F) and applied the receiver operating characteristics (ROC) curves and the area under the ROC curves (AUC) to compare the diagnostic accuracy of the three tools. RESULTS We included 1,009 participants. Using the Youden Index method, the cutoff of the cSARC-CalF for identifying sarcopenia was set as ≥11 points. Both the cSARC-CalF and the SARC-CalF showed better sensitivity but similar specificity than the SARC-F for identifying sarcopenia (sensitivity: 33.3%, 41.4%, and 23.0%; specificity: 90.1%, 85.9%, and 88.1%). The AUCs of the cSARC-CalF, SARC-CalF, and SARC-F were 0.74 (95% CI, 0.71 - 0.77), 0.79 (95% CI, 0.76 - 0.81), and 0.67 (95% CI, 0.64 - 0.70), respectively. The difference in AUCs between cSARC-CalF and SARC-F and the difference in AUCs between SARC-CalF and SARC-F was statistically significant (p=0.012 and p<0.001, respectively). However, the difference in AUCs between cSARC-CalF and SARC-CalF was not significant (p=0.109). CONCLUSION The cSARC-CalF showed a better overall diagnostic accuracy than the SARC-F and a similar overall diagnostic accuracy as the SARC-CalF in Chinese community-dwelling older adults. It may serve as a new tool for screening sarcopenia; however, it needs to be validated in other populations.

Abstract
Few studies focused on the relationship between hepatitis B virus (HBV) infection and classical Hodgkin lymphoma (cHL). This study was to evaluate the impact of HBV infection on the treatment outcome and survival of cHL patients. Clinical data of 352 cHL patients treated with ABVD regimen (doxorubicin, bleomycin, vincristine and dacarbazine) between January 2002 and January 2018 were retrospectively collected. According to HBV infection status, the patients were divided into three groups: with HBV infection [hepatitis B surface antigen (HBsAg)-positive], with past HBV infection [HBsAg-negative but anti-hepatitis B core antigen (anti-HBc)-positive], and without HBV infection (HBsAg-negative and anti-HBc-negative). The incidence of HBV infection and past HBV infection in cHL patients were 7.4% (26/352) and 16.5% (58/352), respectively. The median age of patients without HBV infection was lower than those in other two groups (p<0.001). The complete remission rates after first-line therapy were different among 3 groups (65.4% for the group with HBV infection, 87.9% for the group with past HBV infection, and 76.1% for the group without HBV infection, respectively, p=0.049). After a median follow-up of 34.6 months, the 3-year progression-free survival rates for the three groups were 69%, 74% and 80%, respectively (p=0.566) and the 3-year overall survival rates were 72%, 91% and 87%, respectively (p=0.096). No HBV reactivation was observed during chemotherapy among 3 groups, but 1 patient in the group with HBV infection experienced delayed HBV reactivation when prophylactic entecavir was discontinued 12 months after the last cycle of chemotherapy. HBV infection status did not affect the clinical outcome and prognosis of cHL patients, especially in the era of prophylactic antiviral therapy.

Abstract
Merons which are topologically equivalent to one-half of skyrmions can exist only in pairs or groups in two-dimensional (2D) ferromagnetic (FM) systems. The recent discovery of meron lattice in chiral magnet Co8Zn9Mn3 raises the immediate challenging question that whether a single meron pair, which is the most fundamental topological structure in any 2D meron systems, can be created and stabilized in a continuous FM film? Utilizing winding number conservation, we develop a new method to create and stabilize a single pair of merons in a continuous Py film by local vortex imprinting from a Co disk. By observing the created meron pair directly within a magnetic field, we determine its topological structure unambiguously and explore the topological effect in its creation and annihilation processes. Our work opens a pathway towards developing and controlling topological structures in general magnetic systems without the restriction of perpendicular anisotropy and Dzyaloshinskii–Moriya interaction. A meron is one half of a skyrmion but whether a single meron pair can be created and stabilized remains a challenging question. Here, Gao et al. develop a method to create and stabilize individual pairs of merons in a continuous Py film by local vortex imprinting from Co disks.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is often diagnosed at an advanced and incurable stage. Information on driver genes and prognosticators in ESCC remains incomplete. The objective was to elucidate significantly mutated genes (SMGs), mutational signatures, and prognosticators in ESCC. Patients and methods Three MutSig algorithms (i.e. MutSigCV, MutSigCL and MutSigFN) and '20/20+' ratio-metric were employed to identify SMGs. Nonnegative matrix factorization was used to decipher mutational signatures. Kaplan-Meier survival analysis, multivariate Cox and logistic regression models were applied to analyze association between mutational features and clinical parameters. Results We identified 26 SMGs, including 8 novel (NAV3, TENM3, PTCH1, TGFBR2, RIPK4, PBRM1, USP8 and BAP1) and 18 that have been previously reported. Three mutational signatures were identified to be prevalent in ESCC including clocklike C>T at CpG, APOBEC overactive C>T at TpCp[A/T], and a signature featured by T>C substitution. The T>C mutational signature was significantly correlated with alcohol consumption (OR: 3.59; 95% CI: 2.30-5.67; P < 0.001). This alcohol consumption signature was also observed in liver cancer and head and neck squamous cell carcinoma, and its mutational activity was substantially higher in samples with mutations in TP53. Survival analysis revealed that TENM3 mutations (HR: 5.54; CI: 2.68-11.45; P < 0.001) and TP53 hotspot mutation p.R213* (HR: 3.37; CI: 1.73-8.06; P < 0.001) were significantly associated with shortened survival outcome. The association remained statistically significant after controlling for age, gender, TNM stage and tumor grade. Conclusions We have uncovered several new SMGs in ESCC and defined an alcohol consumption related mutational signature. TENM3 mutations and the TP53 hotspot mutation p.R213* are independent prognosticators for poor survival in ESCC.

Abstract
OBJECTIVE The aim of this study was to elaborate the influence of changing energy metabolism pattern of renal tubular epithelial cells in the process of renal interstitial fibrosis on podocytes. Meanwhile, we also investigated the relationship between energy metabolism pattern and the development of renal interstitial fibrosis. MATERIALS AND METHODS We established a model of renal interstitial fibrosis by unilateral ureteral obstruction (UUO). The protein and messenger RNA (mRNA) expression of fibrosis signs, such as α-smooth muscle actin (α-SMA) and fibronectin (FN) were detected. We also measured the protein and mRNA expression of key glycolytic enzymes, including pyruvate kinase muscle isozyme 2 (PKM2) and human glandular kallikrein 2 (HK2). The proliferation and differentiation of podocytes during fibrosis were observed by monitoring the expression of nephrin and myocardin. In vitro experiments, primary podocytes were extracted, cultured, and stimulated with lactate. Then the alterations during the process were observed. Finally, PKM2 expression was inhibited by intravenous infusion of the plasmid. The link between the expression of marker protein as well as differentiation protein in podocytes and renal interstitial fibrosis was analyzed. RESULTS During the process of renal interstitial fibrosis, phenotypic changes and enhanced expression of fibrosis and proliferation markers were found in fibroblasts. Meanwhile, in renal tubular epithelial cells, increased expression of key enzymes of glycolysis, the level of glycolysis as well as lactate metabolites cooperatively led to hypoxic and acidic environment, eventually inhibiting the proliferation and differentiation of podocytes and aggravating fibrosis. When the level of glycolysis in renal tubular epithelial cells was reduced, the number and function of podocytes were partially restored, and renal interstitial fibrosis was alleviated. CONCLUSIONS During renal interstitial fibrosis, glycolysis of renal tubular epithelial cell was increased, leading to the recodification of energy metabolism. This process affected the number and function of podocytes and aggravated renal interstitial fibrosis.

Abstract
Objective: To explore the relationship between hemoglobin (Hb) level during the first trimester of pregnancy and gestational diabetes mellitus (GDM). Methods: A total of 1 276 participants, who underwent scheduled prenatal examination and normal singleton delivery at the Fifth People's Hospital of Shanghai and Hospital of Intergrated Chinese and Western Medicine in Minhang District, from January 2016 to May 2018 were included. There were 99 cases of GDM (GDM group) and 1 177 cases of normal (control group) pregnant women.Based on the serum Hb level during the first trimester of pregnancy, participants were divided into three groups, 236 cases of low Hb level group (Hb<110 g/L), 868 cases of normal Hb level group (110 g/L≤Hb<130 g/L), and 172 cases of high Hb level group (Hb≥130 g/L). Maternal clinical data were collected, including Hb level during the first trimester of pregnancy, three-point blood glucose (BG) of oral glucose tolerance test (OGTT) and fasting insulin during the second trimester of pregnancy. Homeostasis model assessment of insulin resistance index (HOMA-IR) and homeostasis model assessment of pancreatic β cell function index (HOMA-β) were used to evaluate insulin resistance and pancreatic β cell function. Results: (1) Hb level during the first trimester of pregnancy in GDM group was significantly higher than that in control group [(123±10),(119±11) g/L, P<0.05]. There were no significant difference in gravidity, parity, index of liver and renal function (all P>0.05). (2) Pre-pregnancy body mass index (BMI), 1-hour BG and 2-hour BG of OGTT were significantly increased in the high Hb level group during the first trimester of pregnancy, which were (23±4) kg/m(2), (7.3±2.0) mmol/L, and (6.5±1.4) mmol/L (P<0.05), respectively. The pre-pregnancy BMI, 1-hour BG and 2-hour BG of the normal or low Hb level group were (22±3) kg/m(2), (6.7±1.6) mmol/L, (6.1±1.2) mmol/L; (22±3) kg/m(2), (6.5±1.5) mmol/L, (5.9±1.1) mmol/L, respectively. There were no statistically significant difference in levels of fasting blood glucose, fasting insulin, HOMA-IR and HOMA-β within 3 groups (all P>0.05). (3) In the high Hb level group, prevalence of pregnancy overweight or obesity and GDM were the highest, which were 37.2%(64/172) and 15.1%(26/172), respectively; the differences were statistically significant (all P<0.05). (4) The serum Hb level in the first trimester was positively related with pre-pregnancy BMI (r=0.130, P<0.05), 1-hour BG (r=0.129, P<0.05), 2-hour BG (r=0.134, P<0.05), fasting insulin (r=0.096, P<0.05), and HOMA-IR (r=0.101, P<0.05).Logistic regression indicated that Hb≥130 g/L during the first trimester of pregnancy was an independent risk factor for GDM (OR=2.799, 95%CI: 1.186-6.604; P<0.05). Conclusion: The high level of Hb (Hb≥130 g/L) during the first trimester of pregnancy is associated with GDM.

Abstract
Noninvasive imaging methods for the diagnosis and risk stratification of pheochromocytomas (PHEOs) remain a great clinical challenge. The glucagon-like peptide-1 receptor (GLP-1R) has been validated to be overexpressed in PHEOs and therefore may be a reliable target for PHEOs. In this study, we firstly synthesized a novel radiotracer 68Ga-NOTA-MAL-Cys39-exendin-4 that specifically targets GLP-1R and evaluated the performance of GLP-1R PET for the diagnosis and risk stratification of PHEOs. Cys39-exendin-4 was conjugated to NOTA-MAL and then radiolabeled with 68Ga. The reaction was completed within 20 min with a yield of 91.6 ± 2.8%. In vitro cell uptake studies validated its high specificity. PET images showed promising tumor visualization with high uptake (1.88 ± 0.10 %ID/g for PC-12 poorly differentiated tumors and 1.09 ± 0.003 %ID/g for PC-12 highly differentiated tumors at 30min after injection). There was a significant difference in the uptake of 68Ga-NOTA-MAL-Cys39-exendin-4 between PC-12 poorly and highly differentiated tumors (p < 0.001), but no significant difference could be observed by 18F-FDG PET. Biodistribution results confirmed the findings of GLP-1R PET and demonstrated that 131I-MIBG couldn't be used for the risk stratification of PHEOs. Immunohistochemistry (IHC) staining revealed differences in GLP-1R expression between PC-12 poorly and highly differentiated tumor tissues. These results demonstrated that 68Ga-NOTA-MAL-Cys39-exendin-4 can specifically target GLP-1R with favorable pharmacokinetic properties. GLP-1R PET can be used for PHEOs detection and has potential for the risk stratification of PHEOs.

Abstract
Objective: To investigate the changes of surgical invitations on necrotizing pancreatitis in recent 14 years by reviewing single center data. Methods: One thousand and eighty patients with necrotizing pancreatitis who received surgical invitation were involved in the study.All the patients were treated at Department of Pancreatic Surgery,Union Hospital,Tongji Medical College,Huazhong University of Science and Technology from January 2005 to December 2018. Six hundred and seventy-eight were males and 402 were females. The median (range) age of the study patients was 45 (20-76) years.The etiology of the disease was related to cholelithiasis in 335 cases(31.02%), hyperlipemia in 302 cases(27.96%), alcohol in 226 cases(20.93%), endoscopic retrograde cholangiopancreatography in 28 cases(2.59%), pregnancy in 50 cases(4.63%), idiopathic factors in 72 cases(6.67%) and other causes in 67 cases(6.20%). The patients were divided into two groups according to the time of admission. Group 1 included 1 475 patients that admitted from January 2005 to December 2010, and group 2 included 1 539 patients that admitted from January 2011 to December 2018. The surgical interventions, morbidity and mortality of the two group were compared, and χ(2) test was used for the statistical test. Results: Two hundred and sixty-six among the 1 080 cases were treated with drainage procedures because of the pseudocyst.One hundred and seventy-five drainage procedures were performed between January 2005 and December 2018, which account for 11.87%(175 /1 475) of all patients of necrotizing pancreatitis; 91 drainage procedures were performed between January 2011 and December 2018,which account for 5.91%(91/1 539) of all patients of necrotizing pancreatitis. Eight hundred and fourteen cases received surgical intervention for infection of necrotizing tissues. Of these cases, 410 cases received percutaneous catheter drainage(PCD) of retroperitoneal fluid or residual infection. Debridement of necrotic tissues was performed on 756 cases. Of these cases, 32 cases received minimal invasive retroperitoneal debridement with/without denotes video assistant,4 cases received transluminal endoscopic debridement, 21 cases received laparoscopic debridement, and 709 cases received open laparotic debridement.Three hundred and sixty-five cases were admitted to our institute during January 2005 to December 2010, and the other 391 cases were admitted to our institute from January 2011 to December 2018. Of the first period, all debridement were performed with open laparotic procedures. Of the second period,debridement were performed with open laparotic procedures and minimal invasive procedures. The average times of surgical invasion, morbidity of principal local complications and mortality of the two periods were 1.27 and 1.34,28.22%(103/365) and 29.92%(117/346),and 6.03%(23/365) and 6.91%(27/346), respectively. Conclusions: Minimal invasive procedures can be considered for debridement in patients with necrotizing pancreatitis in some selected conditions.The involvements of minimal invasive procedures in treatment of necrotizing pancreatitis don't decrease the morbidity of principal local complications and mortality in recent years. Rational surgical procedures and appropriate surgical timing are the keys to improve the efficacy of necrotizing pancreatitis.

Abstract
Abstract
Background
Cardiovascular disease is the leading cause of death in the world. The majority of cardiovascular events result from the rupture of vulnerable atherosclerotic plaques, which are characterized by high and active macrophage content. The integrin αVβ3 is expressed by activated macrophages and endothelial cells in atherosclerotic lesions and thus is a marker of high-risk plaques. Therefore, 89Zr-RGD-melanin nanoparticle (MNP) positron emission tomography (PET)/photoacoustic imaging (PAI) imaging of αVβ3 expression in plaques might provide a novel noninvasive biomarker of plaque vulnerability.
Purpose
In this study, the intrinsic photoacoustic signals and the native strong chelating properties with metal ions of MNP, positron-emitting metal ions 89Zr and αVβ3 integrins targeting ability of cyclic c (RGDfC) peptide was employed to construct an efficient nanoplatform. And we evaluated the feasibility of 89Zr-RGD-MNP PET/PAI of αVβ3 expression in vivo and in vitro.
Methods
We conjugated αVβ3 integrins, cyclic c (RGDfC) peptide, to MNP and chelated the long-lived positron-emitting nuclide 89Zr. The bio-stability and targeting action was detected in macrophages. And the PET/PAI imaging was performed in apoE−/− mice with partial carotid ligation leading to atherosclerosis. In PET imaging, tracer uptake was measured in the stenotic areas of the carotid arteries, as well as on the contralateral side at different time points in vivo. In PAI, photoacoustic signal was measured in the atherosclerosis of the carotid arteries in vivo. Melanin staining and immunohistochemistry of αVβ3 expression were detected in atherosclerosis of the carotid arteries.
Results
89Zr-RGD-MNP showed excellent bio-stability and targeting action. PET imaging showed specific tracer accumulation at plaques in the left carotid artery, confirmed by competitive receptor blocking studies and the contrast in the right carotid artery. In the biodistribution studies, the left carotid (5.29%±0.78%) showed higher uptake than the right carotid (2.11%±1.55%). PAI showed the PA signal in the surgery group (452±85 a.u.) were stronger than the control (156±45 a.u.) and blocking group (254±66 a.u). The result was consistent with PET imaging and the presence of nanoparticles, as indicated by pathological examinations. These results presented good in vivo multimodality imaging (PET/PAI) properties.
Conclusions
We have developed 89Zr-labeled atherosclerotic plaques imaging agents based on the natural melanin nanoparticle. 89Zr-RGD-MNP demonstrates specific tracer accumulation in mice atherosclerotic carotid plaques. In this model, its uptake was associated with αVβ3 expression. 89Zr-RGD-MNP is a potential tracer for noninvasive imaging in atherosclerosis.

Abstract
Background This study aimed to identify NOTCH3 mutations and describe the genetic and clinical features and magnetic resonance imaging results in 11 unrelated patients with cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL) from Henan province in China. Material/Methods NOTCH3 was directly sequenced in 11 unrelated patients of Chinese descent. The clinical presentations and magnetic resonance imaging features were retrospectively analyzed in the 11 index patients with a definite diagnosis. Results Seven different mutations were identified in 11 unrelated patients, including 4 novel mutations (p.P167S, p.P652S, p.C709R, and p.R1100H) in China and 3 reported mutations (p.C117R, p.R578C, and p.R607C). Four novel mutations (p.P167S, p.P652S, p.C709R, and p.R1100H) were predicted to be probably pathogenic using an online pathogenicity prediction program through comprehensive analysis. Clinical presentations in symptomatic patients included stroke, cognitive decline, psychiatric disturbances, and migraine. Multiple lacunars infarcts and leukoaraiosis were detected on MRI in most symptomatic patients, while white-matter lesions were identified in the temporal pole or the external capsule in all affected patients. Conclusions The mutation spectrum of CADASIL patients from Henan province in China displayed some differences from that of those reported previously. DNA sequencing was used to diagnose all 11 patients as having CADASIL, and we found 4 novel mutations. The present results further contribute to the enrichment of NOTCH3 mutation databases.

Abstract
The Ising-like antiferromagnet α-CoV2O6 has received considerable interests because of stabilized 1/3 magnetization plateau around 5 K under magnetic field applied along magnetic easy c-axis. In this work, this magnetization plateau was studied by varying temperature or rotating magnetic field. As temperature decreased, this stabilized plateau collapsed, and additional magnetic transitions were observed. As a result, a rich magnetic phase diagram was constructed and extended to temperature lower than previously reported. When magnetic field moved from the c to b (or a) axis, the magnetization plateau developed with field directions and vanished finally when the field was restricted in the ab plane. An impressive observation is that this 1/3-plateau can be stabilized and remain robust even when magnetic field deviated from the c axis, accompanied by the evolutions of the magnetic moments and the critical transition fields. We suppose that the origins of these temperature and angular dependences of the 1/3 magnetization plateau are related to strong spin-orbital coupling. Indeed, electron spin resonance (ESR) measurement gives large Landé factor of 8.9, evidencing that there exists strong spin-orbital coupling.

Abstract
T‐box transcription factor T (TBXT), encoding the brachyury protein, is an embryonic nuclear transcription factor involved in mesoderm formation and differentiation. Previous studies indicate that TBXT mutations are responsible for the tailless or short‐tailed phenotype of many vertebrates. To verify whether the tailless phenotype in fat‐rumped sheep is associated with TBXT mutations, exon 2 of the TBXT gene for 301 individuals belonging to 13 Chinese and Iranian sheep breeds was directly sequenced. Meanwhile, 380 samples were used to detect the genotypes of the candidate variations by mapping to their reads databases in the Sequence Read Archive repository of GenBank. The results showed that one missense mutation, c.334G>T (GGG>TGG) with a completely linked synonymous variant c.333G>C (CCG>CCC) was found to be associated with the ‘tailless’ characteristic in typical fat‐rumped sheep breeds. The c.334G>T transversion led to the conversion of glycine to tryptophan at the 112th amino acid in the T‐box domain of the brachyury protein. In addition, crossbreeding experiments for long‐tailed and tailless sheep showed that CT/CT allele of nucleotides (nt) 333 and 334, a recessive mutation, would cause sheep tails to be shorter, suggesting that these two linked variants at nucleotides 333 and 334 in TBXT are probably causative mutations responsible for the tailless phenotype in sheep.
