Abstract
Objective: To understand the incidence of HIV infections and associated factors among men who have sex with men (MSM) in Jiangsu province. Methods: Based on national AIDS sentinel surveillance in 2019, MSM from 13 cities in Jiangsu were recruited for questionnaire interview and laboratory testing during April to July, 2019. Seropositive samples were tested with Limiting-antigen avidity enzyme immunoassay to detect recent HIV infections. The incidence of HIV infection in MSM were calculated according to the formula and parameters from China CDC. Multivariable logistic regression analysis was used to identify factors associated with recent infection of HIV. Results: A total of 4 469 MSM were subjects and the incidence of HIV infection were 4.5% (95%CI: 3.4%-5.5%).Multivariate logistic regression analysis results showed that compared with these aged ≥40 years, recruitment ways from MSM venues, awareness of AIDS knowledge, non-unprotected anal sex in the past 6 months and non-syphilis infection, those who aged 18-24 years (aOR=2.083,95%CI:1.087-3.990), recruitment ways from VCT clinics (aOR=2.125,95%CI:1.175-3.843), unawareness of AIDS knowledge (aOR=2.456,95%CI:1.109-5.437), unprotected anal sex in the past 6 months (aOR=3.553,95%CI:2.143-5.889) and syphilis infection (aOR=2.414,95%CI:1.033-5.462) were higher risk of HIV infection. Conclusion: The new infection rates of HIV were high in MSM in Jiangsu province. Health education, condom use and HIV/syphilis screening promotions should therefore be top priority in the prevention and control of HIV infection in MSM.

Abstract
Objective: To analyze the efficacy and safety of Daratumumab for the treatment of primary AL light chain systemic amyloidosis. Methods: Twenty one patients who were diagnosed as primary AL light chain systemic amyloidosis and treated with Daratumumab from 7 centers were retrospectively analyzed. Daratumumab was administrated as first line therapy in seven patients and 14 patients with relapsed settings. Hematological response, safety and survival were analyzed. Results: All 7 patients achieved very good partial response (VGPR) or better with first-line application of daratumumab. Three patients died, and the other four achieved organ remission. Among 14 relapsed patients, 2 patients had a difference of free light chain (dFLC) less than 20 mg/L before treatment, and 9 with a dFLC of more than 50 mg/L. All patients reached partial response (PR) or better, including 4 patients with complete response (CR), 3 with VGPR and 2 with PR. The response rate was 100% in 3 patients with dFLC 20-50 mg/L at baseline. The organ remission rate was 50% in patients with heart involvement and 58.3% in patients with kidney impairment. The overall median follow-up period was 5.3 months, and 11 months in surviving patients. One patient died of severe infection and disseminated intravascular coagulation (DIC) with stable amyloidosis. One patient switched to other regimens because dFLC elevated but did not fulfill progressive disease after 2 year application. As to safety, no grade 3/4 infusion reaction developed, and grade 1 infusion reaction occurred in 3 cases during the first infusion. Lymphocytopenia was seen in 75% patients including grade 3 or more in 30% patients. Conclusion: Daratumumab is effective to eliminate serum free light chain in both newly diagnosed and relapsed patients with systemic amyloidosis.

Abstract
Agriculture is a major contributor to marine nitrogen pollution, and treatment wetlands can be a strategy to reduce it. However, few studies have assessed the potential of treatment wetlands to mitigate nitrogen pollution in tropical regions. We quantify the nitrogen removal rates of four recently constructed treatment wetlands in tropical Australia. We measured denitrification potential (Dt), the inflow-outflow of nutrients, and tested whether the environment in these tropical catchments is favourable for nitrogen removal. Dt was detected in three of the four systems with rates between 2.0 and 12.0 mg m-2 h-1; the highest rates were measured in anoxic soils (ORP -100 to 300 mV) that were rich in carbon and nitrogen (>2% and >0.2%, respectively). The highest nitrogen removal rates were measured when NO3--N concentrations were >0.4 mg L-1 and when water flows were slow. Treatment wetlands in tropical regions can deliver high removal rates of nitrogen and other pollutants when adequately managed. This strategy can reduce nutrient loads and their impacts on sensitive coastal zones such as the Great Barrier Reef.

Abstract
BACKGROUND Mycobacteria avium (M. avium) is a species of ubiquitous slowly growing nontuberculous mycobacteria. It causes opportunistic infections. However, M. avium-related peritonitis in peritoneal dialysis (PD) patients is rare. CASE PRESENTATION A 51-year-old female end-stage kidney disease patient undergoing PD was admitted for a noninfectious complication. She presented catheter exit site drainage and slightly increased PD effluent white cell count (WCC) with polymorphonuclear predominance on admission. Exit site infection and PD-related peritonitis were diagnosed. Repeated cultures of effluent and drainage were negative. Initial empirical antibiotics and further adjustment were not rewarding. PD was terminated 2 weeks later, however, shortly the patient developed stupor, high fever, peritoneal irritation, and spontaneous chylous ascites, and showed elevated ascitic adenosine deaminase (ADA). The manifestations persisted and the patient's general condition deteriorated despite intensified antibiotic therapy. Massive parallel sequencing identified M. avium in ascites on hospital day 25, and 4-drug treatment with azithromycin, amikacin, rifampin, and ethambutol was initiated. Nevertheless, the patient died from sepsis on hospital day 30. CONCLUSIONS We report a case of PD-related M. avium peritonitis. Prolonged culture-negative peritonitis, chylous ascites, and elevated ascitic ADA may hint the possibility of mycobacterial infections. Diagnostic method allowing prompt identification of the pathogen is warranted. The prognosis can be extremely poor, and the prophylaxis and treatment should be better defined.

Abstract
Objective: To investigate the interference of daratumumab on immunofixation electrophoresis after treating plasma cell diseases and methods to eliminate the interference. Methods: Serum samples of eight patients with plasma cell diseases treated with daratumumab in Peking University People's Hospital from April 2020 to March 2021 were collected for standard immunofixation electrophoresis and Hydrashift 2/4 daratumumab assay. Results: After treatment, 81.3% (13/16) of the samples showed drug-induced monoclonal antibodies (IgG-κ) . The samples without drug-induced monoclonal bands were related to individual differences, administration intervals, and immunoglobulin levels. Among the samples with IgG-κ monoclonal bands, 76.9% (10/13) could be directly identified as endogenous or exogenous monoclonal bands by immunofixation electrophoresis, and the others (3/13) could be identified by Hydrashift 2/4 daratumumab assay. Conclusion: Hydrashift 2/4 daratumumab assay can remove the band of daratumumab on the immunofixation electrophoresis and help with efficacy evaluation.

Abstract
Objective: The study investigated and analyzed the health-related quality of life of diabetes patients in Gansu province before and after the healthcare reform and its influencing factors, so as to provide scientific evidence to improve the health-related quality of life of diabetes patients. Methods: The study used data of the fourth and sixth national health service household survey in Gansu province before (2008) and after (2018) medical reform separately, and EQ-5D health utility index was calculated on the basis of Chinese time frade-off values for EuroQol Five-Dimensions Questionnaire Utility Value scoring system. Results: Compared with the period before the healthcare reform, the five dimensions of EQ-5D for residents, aged 15 and above in Gansu, changed significantly after the healthcare reform: action capability improved by 8.08% (27.43% vs. 19.35%), self-care improved by 16.16% (26.55% vs. 10.39%), normal activity improved by 8.97% (28.32% vs. 19.35%), pain/discomfort worsened by 1.38% (38.05% vs. 39.43%), anxiety/depression worsened by 1.83% (16.81% vs. 18.64%), and the EQ-VAS score increased by 3.36 (60.53 vs. 63.89). The health utility index increased by 0.04 (0.83 vs. 0.87). Multivariate regression analysis results showed that the dimension influence factors were not completely consistent, on the whole, the health-related quality of life of diabetes patients with older age, lower education level, no physical exercise and multi chronic diseases was worse (P<0.05), and multiple chronic disease had the most serious effect on the health of patients with diabetes. The health-related quality of life of diabetes patients with the medical insurance in urban area and after the new medical reform was higher (P<0.05). Conclusion: The new healthcare reform has active influence on the health-related quality of life of diabetes patients in Gansu province, health care providers and policy makers should pay attention to the impacts of multi prechronic diseases on the health-related quality of life of diabetes patients and the mental health of patients with diabetes.

Abstract
BACKGROUND In the phase III KEYNOTE-061 trial (NCT02370498), pembrolizumab did not significantly improve overall survival versus paclitaxel as second-line therapy for gastric/gastroesophageal junction (GEJ) adenocarcinoma with programmed death-ligand 1 (PD-L1) combined positive score (CPS) ≥1 tumors. The association of tissue tumor mutational burden (tTMB) status and clinical outcomes was determined, including the relationship with CPS and microsatellite instability-high (MSI-H) status. PATIENTS AND METHODS In patients with whole exome sequencing (WES) data [420/592 (71%); pembrolizumab, 218; paclitaxel, 202], the association of tTMB with objective response rate (ORR; logistic regression), progression-free survival (PFS; Cox proportional hazards regression), and overall survival (OS; Cox proportional hazards regression) were measured using one-sided (pembrolizumab) and two-sided [paclitaxel] P values. tTMB was also evaluated using FoundationOne®CDx [205/592 (35%)]. Prespecified equivalent cut-offs of 175 mut/exome for WES and 10 mut/Mb for FoundationOne®CDx were used. RESULTS WES-tTMB was significantly associated with ORR, PFS, and OS in pembrolizumab-treated (all P < 0.001) but not paclitaxel-treated patients (all P > 0.6) in univariate analysis. The area under the receiver operating characteristics curve for WES-tTMB and response was 0.68 [95% confidence interval (CI) 0.56-0.81] for pembrolizumab and 0.51 (95% CI 0.39-0.63) for paclitaxel in univariate analysis. There was low correlation between WES-tTMB and CPS in both treatment groups (r ≤ 0.16). WES-tTMB remained significantly associated with all clinical endpoints with pembrolizumab after adjusting for CPS and with PFS and OS after excluding known MSI-H tumors (n = 26). FoundationOne®CDx-tTMB demonstrated a positive association with ORR, PFS, and OS in pembrolizumab-treated patients (all P ≤ 0.003) but not PFS or OS in paclitaxel-treated patients (P > 0.1). CONCLUSION This exploratory analysis from KEYNOTE-061 is the first to demonstrate a strong association between tTMB and efficacy with pembrolizumab but not paclitaxel in patients with gastric/GEJ adenocarcinoma in a randomized setting. Data further suggest tTMB is a significant and independent predictor beyond PD-L1 status.

Abstract
Objective: To investigate the value of chromosomes 7 and 8 polysomy in circulating tumor cells (CTCs) for the diagnosis of non-small cell lung cancer, and the correlation of CTCs with clinical pathological characteristics and epidermal growth factor receptor (EGFR) mutations in cancer tissue. Methods: Fifty-seven patients with non-small cell lung cancer and 21 patients with benign lung diseases were enrolled at Beijing Chaoyang Hospital, Capital Medical University, Beijing, China from November 2017 to October 2020. Negative enrichment combined with immunofluorescence in situ hybridization (imFISH) was used to identify CTCs polysomy on chromosomes 7 and 8. EGFR mutations in 56 lung cancer patients was detected using ARMS-PCR. Results: CTCs were detected in 93.0% (53/57) of non-small cell lung cancers and 28.6% (6/21) benign lung lesions. The difference between lung cancer patients and the control cohort was statistically significant (P<0.01). Receive operator curve (ROC) analyses showed that, when the cut-off value was 1 cell/3.2 mL, Youden index had the highest sensitivity of 93.0% and specificity of 71.4% (AUC=0.906, 95%CI:0.833-0.980, P<0.01). The positive rate of CTCs in stage Ⅲ-Ⅳ cancers was significantly higher than that in stage Ⅰ-Ⅱ (P=0.023). No significant correlation was observed between positive rate of CTCs or chromosome polysomy and age, gender, smoking status, pathologic types and EGFR mutation status. The number of CTCs in EGFR mutated group was higher than that in the non-mutated group (6.5±1.1 vs. 3.7±0.7, P=0.045). The detection rate for CTCs ≥5 in the EGFR mutated group was also higher than the EGFR non-mutated group (52.0% vs. 19.4%,P=0.010). Conclusion: Detection of CTCs with chromosomes 7 and 8 polysomy has potential value in auxiliary diagnosis of non-small cell lung cancer, and the number of CTCs is correlated to TNM stage and EGFR gene mutation status.

Effects of energy-restricted feeding during rearing on sexual maturation and reproductive performance of Rugao layer breeders. Poult Sci 2021; 100:101225. [PMID: 34237549 PMCID: PMC8267595 DOI: 10.1016/j.psj.2021.101225] [Citation(s) in RCA: 6] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/24/2020] [Revised: 03/22/2021] [Accepted: 04/16/2021] [Indexed: 02/06/2023] Open
Abstract
The aim of this study was to assess the effects of energy-restricted feeding during rearing on the sexual maturation and reproductive performance of Rugao layer breeders. A total of 2,400 8-wk-old Rugao layer breeders were randomly assigned to one of 5 groups (480 pullets per group) with eight replicates and were fed one of 5 diets that were nutritionally similar with the exception of apparent metabolizable energy corrected for nitrogen (AMEn) content (2,850, 2,750, 2,650, 2,550, and 2,450 kcal AMEn/kg) from 8 to 18 wks of age. The daily amount of feed was restricted to the absolute quantity of the diet consumed by laying hens fed 2,850 kcal AMEn per kg diet ad libitum (control). From 18 to 52 wks of age, all hens were fed basal diets ad libitum. The body weight of layer breeders at 18 wks of age decreased linearly with increasing energy restriction (P < 0.001), but caught up within 3 wks of ad libitum feeding (P = 0.290). The coefficient of variation of the body weight of the hens at 18, 21, and 24 wks of age decreased linearly (P = 0.010, 0.025, and 0.041, respectively) with increasing energy restriction during rearing. Energy-restricted feeding delayed sexual organ development at 18, 20, and 22 wks of age, including the number of large yellow follicles, oviduct length, oviduct length index, oviduct index, and ovary stroma index (P < 0.05), and delayed sexual maturity, including the age at laying the first egg and the age at 5% and 50% egg production (P = 0.042, 0.004, and 0.029, respectively). Consequently, egg number from 5% to 50% egg production decreased linearly as the degree of energy restriction increased (P = 0.001) and egg production of hens in the energy-restricted feeding groups was lower than that of hens in the ad libitum feeding group (6.36, 6.43, 6.4, and 4.61% vs. 14.29%; P < 0.05) from 18 to 20 wks of age. Furthermore, egg weight increased linearly as energy restriction increased (P < 0.001) and laying hens in the most severe energy-restricted feeding group had more setting eggs (normal eggs weighing >40 g) than hens in the ad libitum feeding and lighter energy-restricted feeding groups (149.57 vs. 144.34, 142.66, 143.63, and 141.78; P < 0.05). No significant differences were observed in fertility, hatchability of fertile eggs, and hatchability of setting eggs (P = 0.381, 0.790, and 0.605, respectively). In conclusion, moderate energy restriction (85.97%, 2,450 vs. 2,850 kcal AMEn/kg) from 8 to 18 wks of age increased egg weight as well as the production of setting eggs in native layer breeders throughout the laying period, without adverse effects on productive performance from 18 to 52 wks of age, or fertility and hatchability at 52 wks of age.

Abstract
PURPOSE To evaluate the prognostic significance of circulating tumour cell (CTC) number determined on the Epic Sciences platform in men with metastatic castration-resistant prostate cancer (mCRPC) treated with an androgen receptor signalling inhibitor (ARSI). PATIENTS AND METHODS A pre-treatment blood sample was collected from men with progressing mCRPC starting either abiraterone or enzalutamide as a first-, second- or third-line systemic therapy at Memorial Sloan Kettering Cancer Center (Discovery cohort, N = 171) or as a first- or second-line therapy as part of the multicenter PROPHECY trial (NCT02269982) (Validation cohort, N = 107). The measured CTC number was then associated with overall survival (OS) in the Discovery cohort, and progression-free survival (PFS) and OS in the Validation cohort. CTC enumeration was also performed on a concurrently obtained blood sample using the CellSearch® Circulating Tumor Cell Kit. RESULTS In the MSKCC Discovery cohort, CTC count was a statistically significant prognostic factor of OS as a dichotomous (<3 CTCs/mL versus ≥ 3 CTCs/mL; hazard ratio [HR] = 1.8 [95% confidence interval {CI} 1.3-3.0]) and a continuous variable when adjusting for line of therapy, presence of visceral metastases, prostate-specific antigen, lactate dehydrogenase and alkaline phosphatase. The findings were validated in an independent datas et from PROPHECY (HR [95% CI] = 1.8 [1.1-3.0] for OS and 1.7 [1.1-2.9] for PFS). A strong correlation was also observed between CTC counts determined in matched samples on the CellSearch® and Epic platforms (r = 0.84). CONCLUSION The findings validate the prognostic significance of pretreatment CTC number determined on the Epic Sciences platform for predicting OS in men with progressing mCRPC starting an ARSI.

Abstract
Skeletal muscle sodium channelopathies due to SCN4A gene mutations have a broad clinical spectrum. However, each phenotype has been reported in few cases of Chinese origin. We present detailed phenotype and genotype data from a cohort of 40 cases with SCN4A gene mutations seen in neuromuscular diagnostic service in Huashan hospital, Fudan University. Cases were referred from 6 independent provinces from 2010 to 2018. A questionnaire covering demographics, precipitating factors, episodes of paralysis and myotonia was designed to collect the clinical information. Electrodiagnostic studies and muscle MRI were retrospectively analyzed. The clinical spectrum of patients included: 6 Hyperkalemic periodic paralysis (15%), 18 Hypokalemic periodic paralysis (45%), 7 sodium channel myotonia (17.5%), 4 paramyotonia congenita (10%) and 5 heterozygous asymptomatic mutation carriers (12.5%). Review of clinical information highlights a significant delay to diagnosis (median 15 years), reports of pain and myalgia in the majority of patients, male predominance, circadian rhythm and common precipitating factors. Electrodiagnostic studies revealed subclinical myotonic discharges and a positive long exercise test in asymptomatic carriers. Muscle MRI identified edema and fatty infiltration in gastrocnemius and soleus. A total of 13 reported and 2 novel SCN4A mutations were identified with most variants distributed in the transmembrane helix S4 to S6, with a hotspot mutation p.Arg675Gln accounting for 32.5% (13/40) of the cohort. Our study revealed a higher proportion of periodic paralysis in SCN4A-mutated patients compared with cohorts from England and the Netherlands. It also highlights the importance of electrodiagnostic studies in diagnosis and segregation studies.

Abstract
The wide-angle view imaging system, in terms of a tangential view diagnostic with field of view (FOV) of 56.8° and a downward-looking diagnostic from the top of the machine with FOV of 94.7°, has been newly constructed for the first plasma of the HL-2M tokamak achieved in December 2020. Its mission in this stage is to monitor the plasma evolution during its startup, sustainment, and disruption in the visible spectral range as well as the plasma-wall interaction. For the latter ultrawide view diagnostic, nearly three-quarters of the divertor region and half the area of the inner wall are in the view range. Both the diagnostics are characterized by a similar optical structure, i.e., the light emission from the plasma is collected by a front-end lens and transferred through an imaging fiber bundle to the camera. This optical structure is suitable for application in the complex tokamak environment mainly because the fiber bundle is flexible. Photos of glow discharges are acquired prior to the first plasma for testing the FOVs in the vacuum vessel. The spatial resolution is ∼4mm for the tangential view diagnostic and ∼10mm for the downward-looking diagnostic. The temporal resolutions, ranging from 90 to 360 Hz by changing the region of interest or binning acquisition mode of the color camera, are applied to record the plasma evolutions and/or dust creation events during the first plasma campaign.

Abstract
INTRODUCTION Hashimoto's thyroiditis (HT) is one of the most common immune-mediated diseases. It makes thyroid surgery more complicated and difficult because there may be adhesions between the thyroid gland and surrounding structures. However, it is still controversial whether HT patients carry a high risk for postoperative complications of thyroid surgery. The purpose of this study was to investigate the significance of HT for the postoperative complications of thyroid surgery. METHODS A search for studies assessing the postoperative complication risks of HT patients compared with that of patients with benign nodules (BNs) was performed in PubMed, EMBASE and Web of Science. Nine studies (20,118 cases, 1,582 cases of HT and 18,536 cases of BN) were identified, and the data from the relevant outcomes were extracted and analysed. RESULTS There were no significant differences between the HT group and BN group in recurrent laryngeal nerve palsy (RLNP) and permanent hypoparathyroidism (PHP). The rate of transient hypocalcaemia (THC) was significantly higher in the HT group (16.85%) than in the BN group (13.20%). CONCLUSIONS The meta-analysis showed that HT only increased the risk of the postoperative complication THC compared to BN. Understanding the significance of HT in postoperative hypoparathyroidism after thyroid surgery would help clinicians perform sufficient preoperative (and postoperative) assessments and to optimise surgical planning.

Abstract
Abstract
Background
Age-associated deterioration of cognitive function and memory capacity occur in a variety of mammals, from humans to rodents. For example, significant memory deficits have been reported in conventionally raised (SPF) old mice compared to conventionally raised young mice submitted to a spatial memory task (Prevot et al., Mol Neuropsychiatry 2019). Microbiota to brain signaling is now well established in mice, but the extent to which this influences age-related memory decline is unknown.
Aims
Our project aims to determine whether the intestinal microbiota contributes to age-related changes in brain function. We address the hypothesis that age-related cognitive decline is attenuated in the absence of the intestinal microbiota.
Methods
We studied locomotor behavior and spatial memory performance in young germ-free (GF) mice (2–3 months of age, n=24) and senescent GF mice (13–27 months old, n=22) maintained in axenic conditions, and compared them to conventionally raised (SPF) mice. We used the Y-maze test based on a spontaneous alternations task to assess cognition, with alternation rate as a proxy of spatial working memory performance. The locomotor activity was measured using the open-field test.
Results
GF old mice traveled less distance (458.9 cm) than GF young mice (875.7 cm, p < 0.001) but these differences in locomotor activity did not influence spatial memory performance. Indeed, both GF old and GF young mice had an identical alternation rate of 73.3% (p > 0.05). This contrasted with the memory impairment found in old SPF mice that displayed lower alternation rate of 58.3%, compared to that found in young SPF mice (76.2%, p = 0.13).
Conclusions
We conclude that the absence of age-related memory decline in germ-free mice is consistent with a role for the microbiota in the cognitive decline associated with aging, likely through action on the immune system, well documented in SPF mice (Thevaranjan et al., Cell Host & Microbe 2017). We propose that novel microbiota-targeted therapeutic strategies may delay or prevent the cognitive decline of aging.

Abstract
Abstract
Background
Abdominal pain is a common complaint in patients with chronic gastrointestinal disorders. Accumulating evidence suggests that gut microbiota is an important determinant of gut function, including visceral sensitivity. Germ-free (GF) mice have been shown to display visceral hypersensitivity, which normalizes after colonization. Sex also appears to play a key role in visceral sensitivity, as women report more abdominal pain than men. Thus, both gut bacteria and sex are important in the regulation of gut nociception, but the underlying mechanisms remain poorly understood.
Aims
To investigate the role of gut microbiota and sex in abdominal pain.
Methods
We used primary cultures of sensory neurons from dorsal root ganglia (DRG) of female and male conventionally raised (SPF) or germ-free (GF) mice (7–18 weeks old). To study the visceral afferent activity in vitro, calcium mobilization in DRG sensory neurons was measured by inverted fluorescence microscope using a fluorescent calcium probe Fluo-4 (1mM). Two parameters were considered i) the percentage of responding neurons ii) the intensity of the neuronal response. First, DRG sensory neurons were stimulated by a TRPV1 agonist capsaicin (12.5nM, 125nM and 1.25µM) or by a mixture of G-protein coupled receptors agonist (GPCR: bradykinin, histamine and serotonin; 1µM, 10µM and 100µM). We next measured the neuronal production of substance P and calcitonin gene-related peptide (CGRP), two neuropeptides associated with nociception, in response to capsaicin (1.25µM) or GPCR agonists (100µM) by ELISA and EIA, respectively.
Results
The percentage of neurons responding to capsaicin and GPCR agonists was similar in male and female SPF and GF mice. However, the intensity of the neuronal response was higher in SPF male compared to SPF female in response to capsaicin (125nM: p=0.0336; 1.25µM: p=0.033) but not to GPCR agonists. Neuronal activation was similar in GF and SPF mice of both sexes after administration of capsaicin or GPCR agonists. Furthermore, substance P and CGRP production by sensory neurons induced by capsaicin or GPCR agonists was similar in SPF and GF mice, regardless of sex. However, while the response to capsaicin was similar, the GPCR agonists-induced production of substance P was higher in SPF male mice compared to SPF females (p=0.003). The GPCR agonists-induced production of CGRP was similar in SPF male and female mice.
Conclusions
Our data suggest that at the level of DRG neurons, the absence of gut microbiota does not predispose to visceral hypersensitivity. The intensity of DRG neuronal responses to capsaicin and the GPCR agonists-induced production of substance P are higher in male compared to female mice, in contrast to previously published studies in various models of acute and chronic pain. Further studies are thus needed to investigate the role of sex in visceral sensitivity.

Abstract
Objective: To summarize the clinical characteristics and prognosis of 51 patients with Waldenström's macroglobulinemia (WM) and evaluate the efficacy and adverse reactions of ibrutinib in the treatment of WM. Methods: We carried out a single-center retrospective study, including 51 patients with WM of our single center from November 2008 to October 2019. Results: The median age at diagnosis was 65 years with a male-to-female ratio of 2.64∶1. There were 9 (18%) , 21 (41%) , and 21 (41%) ISSWM stage low-, intermediate- and high-risk patients identified, respectively. A total of 27 (73%) patients harbored MYD88(L265P) mutation. The median follow-up time was 38.6 (0.3-120.0) months, the median progression free survival was 46.4 months, and the median overall survival was not reached. The overall remission and major remission rates of patients who received ibrutinib were 87% and 80%, respectively. The median time to achieve at least partial remission of patients treated with ibrutinib was 8 weeks, which was earlier than those treated with other drugs (P<0.05) . Conclusion: WM is often seen in elderly men. MYD88(L265P) had a high frequency in WM. The findings of our study validate the efficacy of ibrutinib monotherapy. Even in patients with advanced age and at high risk of ISSWM, the overall remission rate and major remission rate are high. Ibrutinib is a safe and effective therapy because of its rapid onset and rare serious adverse reactions.

Abstract
PURPOSE A meta-analysis aimed to systematically evaluate the safety and efficiency of I125 irradiation stent placement for patients with hepatocellular carcinoma (HCC) combined with portal vein tumor thrombosis (PVTT). MATERIALS AND METHODS The Cochrane library, PubMed/Medline, EMBASE, CNKI, Wanfang Data and CQVIP were systematically screened out from the earliest to December 2019. The qualities of all included studies were assessed. The primary endpoints were the 6-month, 12-month stent cumulative patency rate and 6-month, 12-month, 24-month overall survival rate while the secondary endpoints were the objective response rate of PVTT, main portal venous pressure changes and treatment-related adverse events. Our meta-analysis was conducted using Stata 12.0 software. RESULTS Totally seven studies with 1018 patients were included in the final analysis, in which 602 patients received TACE and I125 irradiation stent placement, and 416 patients in control group underwent TACE and stent placement without endovascular brachytherapy (EVBT). Meta-analysis showed that the I125 irradiation stent improved the cumulative stent patency rates in 6months [OR=1.65, 95% CI (1.32-2.05), P<0.001] and 12months [OR=2.55, 95% CI (1.90-3.42), P<0.001] and the survival rates in 6months [OR=1.77, 95% CI (1.41-2.22), P<0.001], 12months [OR=3.14, 95% CI (2.24-4.40), P<0.001] and 24months [OR=7.39, 95% CI (3.55-15.41), P<0.001]. However, there was no difference in the objective response rate of PVTT [OR=1.13, 95% CI (0.87-1.48), P=0.365], main portal venous pressure and the occurrence adverse event [OR=0.88, CI=0.72-1.08, P=0.212] between two groups. CONCLUSION I125 irradiation stent seems to be more effective in treating hepatocellular carcinoma with portal vein tumor thrombosis. The usage of portal vein stent combined endovascular brachytherapy has the potential to act as an alternative therapy for HCC with PVTT. On account of the limitation of studies included, more studies with high-level evidence, such as RCTs, are requisite to support the above promising results.

Abstract
Three isotopic tracers ([2,3,3-2H3]-L-serine, [2H11]-L-betaine, and [1-13C]-L-methionine) were administered by amnion injection into 18-day-old chick embryos to investigate the kinetics of methionine metabolism. The embryos utilized were from eggs collected from 34-week-old Cobb 500 broiler breeders that were fed either a control diet containing folic acid (1.25 mg/kg diet) and pyridoxine HCl (5 mg/kg diet) or diets devoid of supplemental pyridoxine or folic acid. Intermediate metabolites of methionine metabolism and polyamines were analyzed in 18-day-old chick embryos. There were no differences in hepatic [2H2] methionine or [2H3] cysteine enrichments or in physiological concentrations of sulfur amino acids for chick embryos from breeders fed the control diet and embryos from breeders fed diets containing no pyridoxine or folic acid. Supplementation of B6 or folic acid did not affect the production of methionine and cysteine in chick embryos. However, breeders fed the control diet with both folic acid and pyridoxine supplementation produced embryos with a two-fold reduction of hepatic homocysteine and increased spermine compared with embryos from breeders fed diets containing no supplemental pyridoxine or folic acid (P < 0.05). Hepatic S-adenosylmethionine for embryos from breeders fed no supplemental B6 was half the concentration compared with embryos from breeders fed the control diet. Embryos from breeders fed the control diet were utilized to determine the proportion of homocysteine going through remethylation and transsulfuration and also to determine the pathway of remethylation. Sixty-five percent of the methyl groups used for homocysteine remethylation from control embryos was via the MFMT pathway. Alternatively, 61% of homocysteine from control embryos was remethylated via the MFMT and the BHMT reactions and 39% of homocysteine was catabolized to cysteine via the transsulfuration pathway. These data show that in embryos, intermediate metabolites of methionine and polyamines increase in concentration when pyridoxine levels are provided in deficient concentrations to the breeder hen. In addition, this research demonstrates that folic acid deficient embryos conserve methionine, rather than catabolize it to cysteine.

Abstract
OBJECTIVES This study aimed to explore the evolutionary stage of the elderly from the normal to the cognitive frailty, and to identify the important factors which influenced the changes of the cognitive frailty stage from the «physiological-psychological-social» perspective. DESIGN A cross-sectional study. SETTING AND PARTICIPANTS A random cluster sampling was used to recruit 4,010 old adults living in community from Shanxi province in China. MEASUREMENTS Data were collected by face-to-face questionnaire survey. Multinomial logistic regression was used to screen the factors contributing to the 6 population groups with various cognitive functions and frailty status. Principal component analysis was used to redefine the evolutionary stages of cognitive frailty, while the orthogonal partial least squares discrimination analysis and binary logistic regression were used to identify the important factors and distinguish different stages and influence directions. RESULTS The factors contributing to the population with various cognitive functions and frailty status were involved in all aspects of «physical-psychological-social». Apart from normal group, other 5 groups were clustered into «stage of frailty change» and « stage of cognitive frailty change». Aging, early onset of chronic diseases, high pain intensity, and poor nutritional status might deteriorate the individual's evolution from "normal stage" to "stage of frailty change", while the increasing social activity might promote the individual's health. Simultaneously, early onset of chronic diseases, high pain intensity and poor nutritional status also played important roles in the evolution of individual from "stage of frailty change" to "stage of cognitive frailty change". CONCLUSION The formation of cognitive frailty might experience the «normal-frailty-cognitive frailty» stages change, and both the prevention and intervention of frailty might delay the occurrence of cognitive frailty. Therefore, the strategies for both prevention and intervention among old adults should be throughout centered on the parts of preventing the premature onset of chronic diseases, carrying out stage-tailored nutrition intervention, and establishing standardized pain management, especially the part of increasing the social activities among older adults.

Abstract
To determine how nuclease deactivated Cas9 (dCas9) or single-guide RNA (sgRNA) expression levels affect the knockdown efficiency of CRISPRi, we created K562 cell clones expressing KRAB-dCas9 protein either with the inducible Tet-on system or with the constitutive SFFV promotor. Single clones were selected by fluorescence-activated cell sorting (FACS) for further study. Six genes with various expression levels were targeted using lentiviral sgRNA from two libraries in four cell clones with various KRAB-dCas9 expression levels. The expression level of dCas9 protein/sgRNA levels and the knockdown efficiency were determined by flow cytometry. The cell clone with the highest KRAB-dCas9 expression level achieved effective CRISPRi knockdown. The data describing this clone were statistically different from that on other clones, indicating the strong KRAB-dCas9 expression might be a prerequisite for CRISPRi. By adopting different multiplicity of infection (MOI) in lentiviral transduction of this clone, we modified the expression level of sgRNA and found that the knockdown efficiency was neither affected by the target gene expression level nor correlated with KRAB-dCas9 levels, which remained relatively constant across all knockdown experiments (coefficient of variation = 2.2%). As an example, the following levels of the knockdowns: 74.72, 72.28 and 39.08% for mmadhc, rpia and znf148 genes, respectively, were achieved. These knockdown efficiencies correlated well with the respective sgRNA expression levels. Linear regression models built using this data indicate that the knockdown efficiency may be significantly affected by the levels of both KRAB-dCas9 and sgRNA. Notably, the sgRNA levels have greater impact, being a major factor affecting CRISPRi efficiency.

Abstract
Sheep is usually a monovular animal; superovulation technology is used to increase the number of offspring per individual and shorten generation intervals. To date, mature FSH superstimulatory treatments have been successfully used in sheep breeding, but much remains unknown about genes, pathways, and biological functions involved in follicular development. Therefore, in this study, we performed transcriptome profiling of small follicles (SFs; 2-2.5 mm), medium follicles (MFs; 3.5-4.5 mm), and large follicles (LFs; > 6 mm) in Mongolian ewes after FSH superstimulation. Furthermore, we identified differentially expressed genes and performed Kyoto Encyclopedia of Genes and Genomes pathway and Gene Ontology enrichment analyses in 3 separate pairwise comparisons. We found that ovarian steroidogenesis was significantly enriched in the SFs versus MFs analysis; the associated genes, cytochrome P450 family 19 (CYP19) and Hydroxy-delta-5-steroid dehydrogenase 3 beta- and steroid delta-isomerase 1 (HSD3B1), were significantly upregulated. Moreover, proline metabolism, glutathione metabolism, and PPAR signaling pathways were significantly enriched in the LFs versus SFs analysis; the associated genes, glutamate-cysteine ligase modifier subunit (GCLM) and cystathionine gamma-lyase (CTH), were significantly upregulated, whereas peroxisome proliferator-activated receptor gamma (PPARγ) was significantly downregulated. In summary, our study provides basic data and possible biological direction to further explore the molecular mechanism of sheep follicular development after FSH superstimulation.

Abstract
OBJECTIVES To examine the diagnostic performance of the Tilburg Frailty Indicator (TFI), 11-factor modified frailty index (mFI-11), and 5-factor modified frailty index (mFI-5) for frailty defined by Frailty Phenotype (FP), as well as to compare the predictive ability of TFI, mFI-11, and mFI-5 for adverse outcomes in hospital among elderly patients undergoing gastric cancer surgery. DESIGN A prospective cohort study. SETTING Hospitalization setting, Nanjing, China. PARTICIPANTS We recruited 259 elderly patients undergoing gastric cancer surgery from a tertiary hospital. MEASUREMENTS Frailty was assessed by the FP, TFI, mFI-11, and mFI-5 before surgery, respectively. The receiver operating characteristic (ROC) curves were plotted to compared the diagnostic performance of TFI, mFI-11, and mFI-5 using FP as the reference. ROC curves were used to examine the performance of TFI, mFI-11, and mFI-5 in predicting adverse outcomes. The area under the curve (AUC)>0.70 was regarded as an indicator of good performance. RESULTS The prevalence of frailty ranged from 8.5% (mFI-11) to 45.9% (TFI). The AUCs of TFI (AUC: 0.764, p<0.001) was significantly greater than that of mFI-11 (AUC: 0.600, p=0.033) and mFI-5 (AUC: 0.600, p=0.0311) in the detection of frailty defined by FP, with quite different sensitivity and specificity at their original cutoffs. TFI and mFI-11 both had statistically significant but similarly inadequate predictive accuracy for adverse outcomes in hospital, including total complications (AUCs: 0.618; 0.621), PLOS (AUCs: 0.593; 0.639), increased hospital costs (AUCs: 0.594; 0.624), and hypoproteinemia (AUCs: 0.573; 0.600). For the mFI-5, only the predictive ability for hypoproteinemia was statistically significant, with poor accuracy (AUC: 0.592, p<0.0055). CONCLUSION The TFI performed slightly better than mFI-11 and mFI-5 in our study. Moreover, future studies are needed to further determine an optimal frailty instrument with great diagnostic and predictive accuracy.

Abstract
Objective: To investigate the consistency of Velum, Oropharygneal, Tongue base, Epiglottis (VOTE) scores between two surgeons with similar clinical experience in obstructive sleep apnea hypopnea syndrome (OSAHS) patients with different degree of disease, and to analyze the influencing factors leading to the difference in score. Methods: This was a cross-sectional study. 64 preoperative drug-induced sleep endoscopy (DISE) videos of OSAHS patients during December 2014 to July 2018, from Nanfang Hospital, Southern Medical University were analyzed. The VOTE score was assessed single-blind by two similar experienced surgeons, and the Kappa value between the two scorers was calculated by the third researcher. According to the characteristics of the case, Fisher's exact test or chi-square test method was used to further explore the factors that influenced the consistency. Results: Sixty-four patients were divided into four groups according to the severity of the disease, including mild (7 cases), moderate (30 cases), severe(18 cases), and extremely severe (9 cases). The scores evaluated between two researchers were analysed for consistency. For mild patients, the two scorers were completely consistent in the configuration and degree of obstruction in the velum and epiglottis (Kappa=1). There was no agreement on whether obstruction or not, obstructed configuration, obstructed degree of the oropharynx and tongue base, and presence of velum and epiglottis obstruction. For moderate patients, the two scorers had a good consistency in the configuration and degree of the velum (0.61≤Kappa≤0.80), and there was no consistency in the evaluation of the degree of tongue base and epiglottis (P>0.05). The consistency of the remaining obstructed conditions in the four planes was generally or moderate (0.21≤Kappa≤0.60). For patients with severe OSAHS, the two raters were completely consistent in the evaluation of palatopharyngeal and epiglottic planes for the presence of obstruction, but there was no consistency in the degree of obstruction. Although the degree of obstruction in the oropharyngeal plane can be assessed with good consistency, the consistency of whether the plane was blocked or not was generally not high. In the assessment of other obstructive conditions in the four planes of severe patients, the agreement between the two scorers was moderate or generally. For extremely severe patients, the two scorers were completely consistent in the evaluation of the velum obstruction, but there was no consistency in the degree of obstruction of the oropharynx and tongue base, and the obstruction configuration and degree of the epiglottis. The evaluation of other obstructed conditions in the four planes is good or moderate. Among the patients with severe OSAHS, the difference in the assessment of obstruction of the oropharynx was associated with tonsil size (P<0.05). Conclusion: When physicians with similar clinical experience scored VOTE, the consistency of whether the velum and oropharyngeal planes are obstructed is related to the severity of the disease. Better consistency is observed among more severe OSAHS patients. The reason for the poor consistency of the oropharyngeal plane in severe OSAHS patients OSAHS is due to the difference of the tonsils size. For severe OSAHS patients with small tonsils, the assessment of whether the oropharynx is obstructed should be more cautious.

Abstract
Mottled eggs in layer chickens are gaining increasing attention because of the economic impact on the egg industry caused by the reduced sale value of commodity eggs. However, the genetic architecture underlying mottled eggs is not well understood. The genetic architecture underlying the mottled egg trait was investigated using genome-wide association studies (GWAS) by high-density arrays, using a total of 407 pink eggs and 799 blue eggs from an F2 resource population generated by crossing Dongxiang Blue-shelled and White Leghorn chickens. The mottled egg score in blue eggs was found to be higher than that in pink eggs. The single-nucleotide polymorphism heritability of mottled egg at laying day and storage for 7 days was 0.18 and 0.20, respectively. Bivariate GWAS provided 29 significant loci, mainly located on GGA2, GGA3, GGA8, GGA10, GGA15, GGA17, and GGA23, affecting mottled egg on laying day. Candidate genes RIMS2, SLC25A32, RIMBP2, VPS13B, and RGS3 were obtained for mottled eggshell by bivariate GWAS and gene annotation. Our findings provide new insights into the genetic architecture of mottled egg in hens, and demonstrate that a genomic selection method would be profitable for breeding out the mottled egg trait.

Abstract
BACKGROUND AND PURPOSE The relationship between glycemic control in patients with type 2 diabetes mellitus and intracranial atherosclerotic plaque features has remained understudied. This study aimed to investigate the association of type 2 diabetes mellitus and glycemic control with the characteristics of intracranial plaques using vessel wall MR imaging. MATERIALS AND METHODS In total, 311 patients (217 [69.8%] men; mean age, 63.24 ± 11.44 years) with intracranial atherosclerotic plaques detected on vessel wall MR imaging were enrolled and divided into 3 groups according to type 2 diabetes mellitus and glycemic control statuses: the non-type 2 diabetes mellitus group, the type 2 diabetes mellitus with good glycemic control group, and the type 2 diabetes mellitus with poor glycemic control group. The imaging features of intracranial plaque were analyzed and compared among the groups. The clinical risk factors for atherosclerosis were also analyzed using logistic regression analysis. RESULTS The plaque length and thickness were significantly higher in the type 2 diabetes mellitus with poor glycemic control group than in the non-type 2 diabetes mellitus group. The prevalence of strongly enhanced plaques was significantly higher in the type 2 diabetes mellitus with poor glycemic control group than in the non-type 2 diabetes mellitus and type 2 diabetes mellitus with good glycemic control groups (92.9%, 63.4%, and 72.7%, respectively; P < .001). Multivariate logistic regression analysis showed a significant association of poor glycemic control with the plaque length (OR = 1.966; 95% CI, 1.170-3.303; P = .011), plaque thickness (OR = 1.981; 95% CI, 1.174-3.340; P = .010), and strongly enhanced plaque (OR = 5.448; 95% CI, 2.385-12.444; P < .001). CONCLUSIONS Poor glycemic control, compared with the history of diabetes, might have a greater impact on the burden and vulnerability of intracranial atherosclerotic plaques.

Abstract
BACKGROUND Primary analysis of the phase III trial BG01-1323L demonstrated that utidelone plus capecitabine significantly improved progression-free survival (PFS) and overall response rate (ORR) versus capecitabine alone in heavily-pretreated patients with metastatic breast cancer (MBC). Here, we report the final overall survival (OS) analysis and updates of other endpoints. PATIENTS AND METHODS In total, 405 patients were randomised 2:1 to receive utidelone (30 mg/m2 IV daily, days 1-5, over 90 min) plus capecitabine (1000 mg/m2 orally b.i.d., days 1-14) or capecitabine alone (1250 mg/m2 orally b.i.d., days 1-14) every 21 days. The secondary endpoint, OS, was estimated using the Kaplan-Meier product-limit approach at a two-sided alpha level of 0.05 after the prespecified 310 death events had been reached. Exploratory analyses of the primary endpoint, PFS, and the secondary endpoint, ORR, were also done. Safety was analysed in patients who had at least one dose of study drug. RESULTS At the final OS analysis, the median duration of follow-up was 19.6 months in the utidelone plus capecitabine group and 15.4 months in the capecitabine alone group. In the intention-to-treat population, 313 deaths had occurred at data cut-off, 203 of 270 patients in the combination group and 110 of 135 in the monotherapy group. Median OS in the combination group was 19.8 months compared with 16.0 months in the monotherapy group [hazard ratio (HR) = 0.75, 95% confidence intervals (CI) 0.59-0.94, P = 0.0142]. The updated analysis of PFS and ORR showed that the combination therapy remained superior to monotherapy. Safety results were similar to those previously reported with respect to incidence, severity and specificity. No late-emerging toxicities or new safety concerns occurred. CONCLUSIONS For heavily-pretreated, anthracycline- and taxane-resistant MBC patients, utidelone plus capecitabine significantly improved OS versus capecitabine alone. These results support the use of utidelone plus capecitabine as a novel therapeutic regimen for patients with MBC.
