Abstract
Objective: To analyze the characteristics and prognosis of hearing loss in children with bacterial meningitis. Methods: This was a single-center retrospective cohort study. Patients diagnosed with bacterial meningitis who were hospitalized in Beijing Children's Hospital between 2010 and 2016 and older than 28 days and younger than 18 years at symptom onset were included in this study (n=573). All clinical information including hearing assessment results during hospitalization were reviewed. All patients with hearing loss were followed up to repeat their hearing test and assess their hearing condition with parents' evaluation of aural and (or) oral performance of children (PEACH). Patients were grouped according to their hearing assessment results, and Logistic regression analysis was used to analyze the risk factors for hearing loss in patients with bacterial meningitis. Results: Five hundred and seventy-three patients were enrolled in this study, including 347 males and 226 females. The onset age ranged from 29 days to 15.8 years. Two hundred and forty-six patients had identified causative pathogens, among whom 92 cases (37.4%) were pneumococcal meningitis cases. Hearing loss was found in 160 cases (27.9%) during hospitalization, involving 240 ears. Permanent hearing loss was found in 20 cases (16.9%), involving 32 ears. In the patients with permanent hearing loss, 87.5% (28/32) of ears were identified as severe or profound hearing loss during hospitalization. Logistic regression analysis showed that dystonia, the protein concentration level in cerebrospinal fluid>1 g/L, glucose concentration level lower than 1 mmol/L and subdural effusion were independent risk factors for hearing loss (OR=2.426 (1.450-4.059), 1.865 (1.186-2.932), 1.544 (1.002-2.381) and 1.904 (1.291-2.809)). Conclusions: Hearing loss is a common sequela of bacterial meningitis in children. Most patients have transient hearing loss, but patients with severe or profound hearing impairment have a higher risk of developing permanent hearing loss.

Abstract
Objective: To investigate the correlation between collateral flow compensation mode and interventional treatment decision in patients with severe bilateral internal carotid artery stenosis/occlusion. Methods: According to the location of internal carotid artery lesions, patients with severe stenosis/occlusion of bilateral internal carotid artery were selected at the Second Affiliated Hospital, Qiqihar Medical University and the Sixth Medical Center of PLA General Hospital from May 2017 to June 2020. Results: A total of 42 patients were finally enrolled and divided into 4 types, including 34 males and 8 females with median age 61±8(48-82)years. The collateral circulation pathways manifested as following modes: anterior communicating artery collateral, posterior communicating artery collateral, ophthalmic artery collateral, posterior cerebral middle cerebral artery pial anastomosis collateral, posterior choroidal artery anterior choroidal artery collateral, external carotid internal carotid artery C4 segment collateral, pericallosal artery anastomosis collateral, dural and pial collateral and neovascularization. Type Ⅰ severe stenosis/occlusion of C1 segment was found in 20 cases (47.6%). There were 5 cases (11.9%) of type Ⅱ severe stenosis/occlusion from C2 to C6 prior to ophthalmic artery branch. Type Ⅲ severe stenosis/occlusion occurred in 2 cases (4.8%) after the split of ophthalmic artery. Type Ⅳ was mixed type in 15 cases (35.7%). Conclusions: The compensatory pathway of collateral circulation is closely related to the lesion location. To explore the compensatory pattern of collateral circulation is helpful for clinicians to accurately analyze the lesion characteristics and guide individualized interventional therapy.

Abstract
To elucidate current domestic factors influencing pharmacogenomics (PGx) implementation and its future in China, we conducted a questionnaire survey on PGx applications and testing. A questionnaire-based survey was created on the popular online professional survey platform "Wenjuanxing" (www.wjx.cn) and performed via the social media platform WeChat. Among 422 participants, there were physicians (27.7%), pharmacists (31.3%), and researchers (41.0%). We found that less than 50% of physicians were aware of the importance of PGx in drug therapy, while over 50% of pharmacists and researchers recognized the importance. Only 38.5% of physicians, 40.9% of pharmacists, and 55.5% of researchers concurred that PGx analysis could lower the economic burdens for patients. However, most of the responders affirmed that PGx should be effectively implemented in clinical practices. A lack of sector standards, a lack of clinical research, and a lack of guidelines were found to be the major factors for hindering PGx clinical application. Among drugs associated with PGx assays, the most common were warfarin and clopidogrel. Although PGx research has advanced rapidly in recent years in mainland China, the clinical implementation of PGx has a long way to go.

Abstract
Objective: To explore the influence of hemodynamics, morphological and clinical characteristics on rupture risk of the dorsal and non-dorsal internal carotid artery aneurysms (ICAAs). Methods: A total of 111 patients diagnosed with aneurysm by digital subtraction angiography (DSA) or surgery, underwent cranial CT angiography (CTA) were retrospectively collected from January 2010 to December 2016 at the Department of Diagnostic Radiology, Jinling Clinical College of Xuzhou Medical University (General Hospital of Eastern Theater Command). Among them, 41 were males and 70 were females, ranging in age from 32 to 83 (56±11) years old. The patients were divided into the ruptured group (n=54) and unruptured group (n=57) based on the hemorrhagic manifestation on non-enhanced CT images or DSA or surgery of the head. Demographics and the morphological characteristics of the aneurysms were evaluated. Hemodynamic parameters, including wall share stress, wall share stress gradient, and others were obtained in overall using computational fluid dynamics simulation technique. Characteristics were compared between the ruptured and unruptured groups. Logistic regression analysis was applied to evaluate the independent risk factors for rupture, and the hemodynamic characteristics associated with dorsal and non-dorsal aneurysms were analyzed, respectively. Results: Compared with the unruptured group, patients in the ruptured group were younger ((54.2±11.4) years and (58.3±9.9) years, P=0.033), mostly female (74.1% vs 52.6%, P<0.05), with a higher proportion of hypertension (46.3% vs 22.8%, P=0.009). The ruptured internal carotid artery aneurysms (ICAAs) were more frequently located at the dorsal of an arterial arch (57.4% vs 36.8%, P<0.05), and the flow of the blood was more complex, concentrated, unstable, and with a smaller impingement zone (68.5% vs 33.3%,55.6% vs 10.5%,72.2% vs 26.3% and 79.6% vs 36.8%, respectively, all P<0.05). Logistic regression demonstrated that women, hypertension, dorsal, concentrated flow pattern, and unstable flow pattern were an independent risk factors for ICAAs rupture [OR=3.551 (1.080-11.679), 3.900 (1.172-12.976), 4.966 (1.504-16.401), 51.893 (7.913-340.296) and 50.015 (8.423-296.985), respectively, all P<0.05]. The ruptured ICAAs located at non-dorsal had more concentrated, unstable, and with smaller impingement zone (P<0.05), while those at dorsal had more complex, concentrated, and unstable flow patterns, and with smaller impingement zone (all P<0.05). Conclusion: Women, hypertension, dorsal concentration, and unstable flow pattern are independent risk factors for the rupture of ICAAs. The dorsal locations of ICAAs could have a higher risk of rupture.

Abstract
As potential substitutes for traditional free-range rearing system, floor-rearing system (FRS) and net-rearing system (NRS) are the current predominant dryland duck rearing systems. However, the influence of these two systems on production performance and duck health is poorly understood. In this study, a 2 × 3 factorial arrangement with two rearing systems (FRS and NRS) and three ages (4w, 8w and 13w) was conducted to study the effects of FRS and NRS on production, antioxidant capacity and immune status of Nonghua ducks. The production performance was mainly affected by the effect of rearing systems at 8w. Body weight, average daily gain, eviscerated weight and semi-eviscerated weight were higher in NRS ducks at 8w, but carcass yield at 8w and 13w was decreased (P < 0.05). Lipid deposition was enhanced in NRS and higher sebum and abdominal fat yields were seen at 8w and 13w (P < 0.05). NRS resulted in developmental retardation of the liver at 4w and decreased gizzard index at all ages (P < 0.05). Antioxidant capacity indicators were unaffected by rearing systems (P > 0.05), however, in NRS, slightly better antioxidant capacity was seen at 4w, while glutathione peroxidase (GSH-Px) activity was higher at 13w (P < 0.05). NRS ducks had higher thymus weight at 8w and higher spleen weight at 13w (P < 0.05). Immune cytokines were extensively affected by rearing system (P < 0.05) and higher levels of interferon-γ, interleukin-1β, interleukin-4 and immunoglobulins were seen in NRS ducks. Serum biochemical parameters (aspartate aminotransferase (AST), alanine aminotransferase (ALT) and alkaline phosphatase (ALP)) showed that NRS was better for liver health, and in the liver of FRS ducks, ALP was higher at 13w, and both ALP and interferon-γ were higher at 13w than at 4w and 8w (P < 0.05). In conclusion, this study showed that NRS was, to an extent, conducive to production performance and duck liver health, but compared to FRS, defects were seen in visceral organ development and lipid deposition. Although antioxidant capacity was not significantly affected, NRS ducks may have better antioxidant capacity at the early breeding stage, and GSH-Px activity was increased for scavenging excess free radicals at the later one. NRS increased serum levels of interferon-γ, interleukin-1β, interleukin-4 and immunoglobulins and promoted thymus and spleen development, thus improving duck immune function. These findings will provide a reliable reference for selecting a rearing system.

Abstract
Children are susceptible to allergic rhinitis (caused by external allergens) accompanied by functional gastrointestinal disease, which seriously affects physical and mental health. Antihistamines and nasal spray hormones are commonly used in clinical treatment, but these drugs often have unsatisfactory efficacy and result in high recurrence rates. Therefore, understanding the pathogenesis of allergic rhinitis with functional gastrointestinal disease and seeking safer treatment and prevention methods is essential. Herein, molecular ecology and immunoassays were used to analyze correlations between pediatric allergic rhinitis with functional gastrointestinal disease and both the intestinal microbiota and gastrointestinal peptide levels. Fifty healthy children (healthy group) and 80 children with allergic rhinitis with functional gastrointestinal disease (case group: evenly divided into a control group (conventional drug therapy) and an intervention group (conventional drug therapy + glutamine+probiotics)), were enrolled. Bifidobacterium and Lactobacillus counts and the gastrin and motilin levels were lower in the case group than in the healthy group, whereas Enterobacter, yeast, and Enterococcus counts and the somatostatin, serotonin, and vasoactive intestinal peptide levels were higher. Post treatment, intestinal microbiota indices, gastrointestinal peptide levels, and intestinal barrier function were better in the intervention group than in the control group (p < 0.05). The intervention group had a significantly higher total therapeutic response rate (95.00%) than the control group (77.50%). The intestinal microbiota was closely associated with gastrointestinal peptide levels. Treatment with glutamine and probiotics regulated these levels, re-established balance in the intestinal microbiota, and restored intestinal barrier function.

Abstract
BACKGROUND AND PURPOSE Small intracranial aneurysms are being increasingly detected while the rupture risk is not well-understood. We aimed to develop rupture-risk models of small aneurysms by combining clinical, morphologic, and hemodynamic information based on machine learning techniques and to test the models in external validation datasets. MATERIALS AND METHODS From January 2010 to December 2016, five hundred four consecutive patients with only small aneurysms (<5 mm) detected by CTA and invasive cerebral angiography (or surgery) were retrospectively enrolled and randomly split into training (81%) and internal validation (19%) sets to derive and validate the proposed machine learning models (support vector machine, random forest, logistic regression, and multilayer perceptron). Hemodynamic parameters were obtained using computational fluid dynamics simulation. External validation was performed in other hospitals to test the models. RESULTS The support vector machine performed the best with areas under the curve of 0.88 (95% CI, 0.85-0.92) and 0.91 (95% CI, 0.74-0.98) in the training and internal validation datasets, respectively. Feature ranks suggested hemodynamic parameters, including stable flow pattern, concentrated inflow streams, and a small (<50%) flow-impingement zone, and the oscillatory shear index coefficient of variation, were the best predictors of aneurysm rupture. The support vector machine showed an area under the curve of 0.82 (95% CI, 0.69-0.94) in the external validation dataset, and no significant difference was found for the areas under the curve between internal and external validation datasets (P = .21). CONCLUSIONS This study revealed that machine learning had a good performance in predicting the rupture status of small aneurysms in both internal and external datasets. Aneurysm hemodynamic parameters were regarded as the most important predictors.

Abstract
1. Granulosa cells (GCs) are involved in folliculogenesis, follicular development, and atresia. Previous studies have shown that microRNA-181a-5p (miR-181a-5p) and sirtuin 1 (SIRT1) are involved in GC proliferation and apoptosis, and SIRT1 has been predicted as one target of miR-181a-5p. However, there are few studies with poultry.2. Quantitative real-time PCR (qRT-PCR) was used to detect the expression level of miR-181a-5p in granulosa layers during geese ovarian follicular development. A methyl thiazolyl tetrazolium (MTT) assay was performed to assess the viability of geese granulosa cells treated with miR-181a-5p mimic or inhibitor. The binding sites between the SIRT1 3'-UTR region and miR-181a-5p were evaluated using a luciferase reporter assay system. SIRT1 mRNA levels were detected using qRT-PCR after transfection with miR-181a-5p mimic and inhibitor.3. The miR-181a-5p suppressed geese GC viability and regulated the mRNA expression of viability-related genes in geese GCs. SIRT1 was a target gene of miR-181a-5p and miR-181a-5p suppressed its mRNA expression.4. The miR-181a-5p may target and inhibit SIRT1 expression, thus suppressing GC viability by regulating viability-related key genes.

Abstract
Low back pain (LBP) is a common musculoskeletal symptom, which can be developed in multiple clinical diseases. It is widely recognized that intervertebral disc (IVD) degeneration (IVDD) is one of the leading causes of LBP. However, the pathogenesis of IVD-related LBP is still controversial, and the treatment means are also insufficient to date. In recent decades, the role of structure and function changes of sensory nervous system in the induction and the maintenance of LBP is drawing more and more attention. With the progress of IVDD, IVD cell exhaustion and extracellular matrix degradation result in IVD structural damage, while neovascularization, innervation and inflammatory activation further deteriorate the microenvironment of IVD. New nerve ingrowth into degenerated IVD amplifies the impacts of IVD-derived nociceptive molecules on sensory endings. Moreover, IVDD is usually accompanied with disc herniation, which could injure and inflame affected nerves. Under mechanical and pro-inflammatory stimulation, the pain-transmitting pathway exhibits a sensitized function state and ultimately leads to LBP. Hence, relevant pathogenic factors, such as neurotrophins, ion channels, inflammatory factors, etc., are supposed to serve as promising therapeutic targets for LBP. The purpose of this review is to comprehensively summarize the current evidence on 1) the pathological changes of sensory nervous system during IVDD and their association with LBP, and 2) potential therapeutic strategies for LBP targeting relevant pathogenic factors.

Abstract
Objective: Currently, various treatments such as hemorrhoidectomy, ligation and sclerotherapy injection can be applied in grade II or III hemorrhoids. This study aims to compare the clinical efficacy, safety and economy between Shaobei injection and elastic band ligation in treating patients with grade II or grade III hemorrhoids. Methods: A retrospective cohort study was used. Clinical data of 60 patients with grade II or grade III hemorrhoids at Department of Anorectal Surgery of the Sixth Affiliated Hospital, Sun Yat-sen University between January 2019 and October 2019 were collected. Patients were divided into two groups according to surgical methods. Patients in the Shaobei group received Shaobei injection (n=28), and those in the ligation group received elastic band ligation (n=32). Inclusion criteria: (1) diagnosis of grade II or III hemorrhoid; (2) application of Shaobei injection or elastic band ligation; (3) age between 18-75 years old. Exclusion criteria: (1) comorbidity with anal fissure, anal fistula, anal sinusitis or other perianal diseases; (2) patients with mental disorder or poor compliance; (3) incomplete clinical or follow-up data. Recurrent rate, postoperative pain, anal edema, anal distension, total cost of hospitalization, length of hospitalization, and postoperative life quality EQ-5D-3L score were compared between the two groups at postoperative 6-month. Results: No significant difference was observed in the baseline data (including Nystrom hemorrhoid symptom score) between the two groups (all P>0.05), except gender ratio [male proportion: Shaobei 75% (21/28) vs. ligation 37.5%(12/32), χ(2)=8.485, P=0.004]. No significant difference in recurrent rate was found between the two groups [14.3% (4/28) vs. 9.4% (3/32), χ(2)=0.035, P=0.851]. Compared to the ligation group, Shaobei group showed less pain at postoperative day 1 [VAS median (range): 2 (1-6) vs. 3 (1-7), Z=2.814, P=0.005] and postoperative day 7 [VAS median (range): 0 (0-2) vs. 1 (0-4), Z=3.149, P=0.002]; lower anal edema ratio at postoperative day 1 [10.7% (3/28) vs. 34.4% (11/32), Z=4.673, P=0.037]; lower anal distension ratio at postoperative day 1 [7.1% (2/28) vs. 28.1% (9/32), Z=4.391, P=0.048]; less hospitalization cost [(6343.5±1444.1) yuan vs. (10 587.1± 1719.0) yuan, t=12.515, P<0.001] and shorter postoperative hospital stay [median (range): 1 (1-5) days vs. 3 (1-6) days, Z=5.879, P<0.001]. The EQ-5D-3L scores of two groups were significantly improved six months after treatment [Shaobei group: (0.90±0.16) vs. (0.73±0.14); ligation group: (0.91±0.13) vs. (0.74±0.10); both P<0.001], while there was no statistically significant difference between the two groups (t=0.130, P=0.897). No complications such as massive hemorrhage, infection, iatrogenic anal fistula, rectal stricture and local induration occurred after the injection. Conclusions: Shaobei injection is effective and safe in treating grade II or III hemorrhoids. Compared with elastic band ligation, it can reduce morbidity of complications and hospitalization expenses.

Comparison of overfeeding effects on gut physiology and microbiota in two goose breeds. Poult Sci 2020; 100:100960. [PMID: 33652539 PMCID: PMC7936201 DOI: 10.1016/j.psj.2020.12.057] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/24/2020] [Revised: 12/16/2020] [Accepted: 12/20/2020] [Indexed: 01/22/2023] Open
Abstract
To have a better understanding of how the “gut–liver axis” mediates the lipid deposition in the liver, a comparison of overfeeding influence on intestine physiology and microbiota between Gang Goose and Tianfu Meat Goose was performed in this study. After force-feeding, compared with Gang Goose, Tianfu Meat Goose had better fat storage capacity in liver (397.94 vs. 166.54 for foie gras weight (g), P < 0.05; 6.37 vs. 2.92% for the ratio of liver to body, P < 0.05; 60.01 vs. 46.64% for fat content, P < 0.05) and the less subcutaneous adipose tissue weight (1240.96 g vs. 1440.46 g, P < 0.05). After force-feeding, the digestion–absorption capacity of Tianfu Meat Goose was higher than that of Gang Goose (5.56 vs. 3.64 and 4.63 vs. 3.68 for the ratio of villus height to crypt depth in duodenum and ileum, respectively, P < 0.05; 1394.96 vs. 782.59 and 1314.76 vs. 766.17 for the invertase activity (U/mg-prot), in duodenum and ileum, respectively, P < 0.05; 6038.36 vs. 3088.29 and 4645.29 vs. 3927.61 for the activity of maltase (U/mg-prot), in duodenum and ileum, respectively, P < 0.05). Force-feeding decreased the gene expression of Escherichia coli in the ileum of Tianfu Meat Goose; force-feeding increased the number of gut microbiota Enterobacterial Repetitive Intergenic Consensus-Polymerase Chain Reaction band in Tianfu Meat Goose and decreased the number in Gang Goose. In conclusion, compared with Gang Goose, the lipid deposition in the liver and the intestine digestion–absorption capacity and stability were higher in Tianfu Meat Goose. Thereby, Tianfu Meat Goose is the better breed for foie gras production for prolonged force-feeding; Gang Goose possesses better fat storage capacity in subcutaneous adipose tissue. However, Gang Goose has lower gut stability responding to force-feeding, so Gang Goose is suited to force-feeding in a short time to gain the body weight and subcutaneous fat as an overfed duck for roast duck.

[PMID: 33650641 PMCID: PMC7859924 DOI: 10.3892/or.2020.7905] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2020] [Accepted: 11/20/2020] [Indexed: 12/28/2022] Open
Abstract
The aim of the present study was to explore the mechanism by which microRNA (miR)-642a-5p regulates the migration and invasion of colon cancer cells via collagen type I α1 (COL1A1). The characteristics of miR-642a-5p and COL1A1 were analysed through bioinformatics. Cancer and normal tissues were collected from patients with colon cancer. miR-642a-5p- and COL1A1-overexpressing cell lines were constructed by transfection. A Dual-luciferase reporter assay was used to verify the targeting of COL1A1 by miR-642a-5p. Cell Counting Kit-8, wound healing and Transwell assays were used to detect cell viability, migration and invasion, respectively. Protein and mRNA expression levels were examined by western blotting and reverse transcription-quantitative PCR, respectively. The results revealed that miR-642a-5p expression was significantly upregulated and COL1A1 expression was downregulated in patients with colon cancer. Low levels of miR-642a-5p and high levels of COL1A1 were associated with a poor prognosis in patients with colon cancer. miR-642a-5p directly targeted the 3′-untranslated region of COL1A1 and inhibited COL1A1 expression. Overexpression of miR-642a-5p inhibited cell viability, migration, invasion and epithelial mesenchymal transition. Overexpression of COL1A1 promoted cell viability, migration, invasion and EMT, and partially reversed the inhibitory effects of miR-642a-5p on colon cancer cells. In conclusion, miR-642a-5p inhibited colon cancer cell migration, invasion and EMT by regulating COL1A1.

Abstract
The research and development of innovative drugs targeting the clinical cure of chronic hepatitis B has become active in recent years. In the clinical trials of new drugs for hepatitis B, the use of new design concepts, new methods, and new technologies to evaluate the efficacy of innovative drugs is expected to shorten the clinical research process of candidate new drugs and reduce the cost of new drug development. However, the new designs such as seamless adaptive design and master plan design have few practical applications in clinical trials of innovative hepatitis B drugs. This article will focus on the methodological factors in the design of phase II/III clinical trials of innovative hepatitis B drugs, and introduce the key points of the new clinical trial design in order to provide methodological references for the development of innovative hepatitis B drugs.

Abstract
Naringinase was mainly obtained by microbial fermentation, and mutagenesis was a major way for obtaining excellent mutants. The aim of this study was to screen out a high naringinase yielding mutant to enhance the potential application value of its industrialization and compare the effects of different mutagenic methods on the enzyme activity of the strain. A novel producing naringinase strain, Aspergillus tubingensis MN589840, was isolated from mildewed pomelo peel, later subjected to mutagenesis including UV, ARTP and UV-ARTP. After five rounds iterative mutagenesis, the mutants U1, A6 and UA13 were screened out with 1448·49, 1848·71, 2475·16 U mg-1 enzyme activity, the naringinase productivity raised by 79·08, 123·56 and 206%, respectively. In addition, the naringinase activity of three mutants rose after each round of iterative mutagenesis. These results indicated that the mutagenesis efficiency of UV-ARTP was higher than that of single ARTP, and both are better than UV. In summary, the iterative UV-ARTP mutagenesis is an effective strategy for screening high naringinase-producing strains.

Abstract
Abstract
Background
Hypertension and grip strength (GS) are predictors of mortality and cardiovascular disease (CVD), but whether these risk factors interact to affect both CVD and all-cause mortality is unknown. The study aimed to examine whether the associations between hypertension and GS with the risk of major CVD incidence, CVD mortality, and all-cause mortality differed between people with and without hypertension.
Methods
GS was measured using a Jamar dynamometer in participants aged 35–70 years from 12 provinces in the Prospective Urban Rural Epidemiology (PURE) China study. Hypertension was defined as a baseline systolic and diastolic blood pressure of at least 140/90 mm Hg, a self-reported history of hypertension, or treatment with antihypertensive medications. Cox proportional hazards models were used to examine the associations of GS and hypertension and with the outcomes of all-cause mortality and CVD incidence/mortality, and to test the multiplicative interactions between hypertension and GS.
Results
Among 39,862 participants included in this study, 15,964 reported having hypertension at baseline and 9095 had high GS. After a median follow-up of 8.9 years [interquartile range (IQR) 6.7–9.9 years], 1822 participants developed major CVD, and 1250 deaths occurred (388 as a result of CVD). Compared with normotensive participants with high GS, hypertensive patients with high GS had a higher risk of major CVD incidence (HR 2.36 [95% CI: 1.84–3.02]; P<0.0001) or CVD mortality (HR 3.05 [95% CI: 1.56–5.95]; P<0.0001) but did not have a significantly increased risk of all-cause mortality (HR 1.23 [95% CI: 0.91–1.67]; P=0.181); these risks were further increased if hypertensive participants whose GS level was low (major CVD incidence (HR 3.33 [95% CI: 2.61, 4.24]; P<0.0001), CVD mortality (HR: 5.20 [95% CI: 2.76, 9.82]; P<0.0001), and all-cause mortality (HR 2.00 [95% CI: 1.53, 2.62]; P<0.0001)).
Conclusions
The present study demonstrates that hypertensive patients with low GS are associated with the highest risk of major CVD incidence, CVD mortality, and all-cause mortality. High levels of GS appear to mitigate long-term mortality risk among hypertensive patients.

Abstract
Objective: To understand the characteristics and differences of diarrhea-related symptoms caused by different pathogens, and the clinical features of various pathogens causing diarrhea. Methods: Etiology surveillance program was conducted among 20 provinces of China from 2010 to 2016. The acute diarrhea outpatients were collected from clinics or hospitals. A questionnaire was used to survey demographics and clinical features. VFeces samples were taken for laboratory detection of 22 common diarrhea pathogens, to detect and analyze the clinical symptom pattern characteristics of the patient's. Results: A total of 38 950 outpatients were enrolled from 20 provinces of China. The positive rates of Rotavirus and Norovirus were the highest among the five diarrhea-causing viruses (Rotavirus: 18.29%, Norovirus: 13.06%). In the isolation and culture of 17 diarrhea-causing bacterial, Escherichia coli showed the highest positive rates (6.25%). The clinical features of bacterial diarrhea and viral diarrhea were mainly reflected in the results of fecal traits and routine examination, but pathogenic Vibrio infection was similar to viral diarrhea. Conclusion: Infectious diarrhea presents different characteristics due to various symptoms which can provide a basis for clinical diagnosis.

Abstract
Circular ATP binding cassette subfamily B member 10 (circABCB10) has been identified to have oncological functions in several tumors. However, the roles of circABCB10 in rectal cancer remain unknown. The expression of circABCB10, microRNA (miR)-326 and C-C motif chemokine ligand 5 (CCL5), and apoptosis related-protein was detected using quantitative real-time polymerase chain reaction or western blot, respectively. Cell survival or apoptosis was measured using cell counting kit-8 assay or flow cytometry. The accumulations of intracellular lipid reactive oxygen species (ROS) and Fe2+ were analyzed using C11-BODIP dye or iron kit assay, respectively. In vivo experiments were conducted using the murine xenograft model. The interaction between miR-326 and circABCB10 or CCL5 was confirmed by dual-luciferase reporter assay and RNA immunoprecipitation assay. CircABCB10 and CCL5 were upregulated but miR-326 was downregulated in rectal cancer. The knockdown of circABCB10 promoted rectal cancer cell ferroptosis and apoptosis in vitro as well as inhibited tumor growth in vivo. miR-326 was a target of circABCB10, and the miR-326 inhibition could partially attenuate circABCB10 deletion-induced cell ferroptosis and apoptosis. miR-326 directly interacted with CCL5, and the miR-326 inhibition suppressed cell ferroptosis and apoptosis by targeting CCL5. Besides, we observed that miR-326 was negatively regulated by circABCB10, while CCL5 was positively regulated by it, and circABCB10 served as a sponge of miR-326 to regulate the CCL5 expression in rectal cancer cells. CircABCB10 silence promoted rectal cancer cell ferroptosis and apoptosis by regulating the miR-326/CCL5 axis, suggesting a potential therapeutic target for rectal cancer therapy.

Abstract
Abstract
Nobel Laureate von Békésy first presented traveling wave theory, which explains the vibration mechanism of the basilar membrane (BM) of cochlea in 1960, and thus the mysterious veil of passive phonoreceptive mechanism of human cochlea was unveiled. However, the interpretation of active phonoreceptive mechanism of human cochlea has been a major medical problem for mankind. The active mechanism can be reflected in structures and the perilymph where a series of complex coupling nonlinear motion process is observed in the cochlea. Because the cochlea is small and complex, vibration data of the whole BM are not yet available from existing experiments. To address the problem, first, the motion equations of the organ of Corti (OHC) are established, and the circuit equations of the outer hair cells (OHCs) in the perilymph and the relationship between the motion of the outer hair cells and the electromotile force are derived. Then the active feedback force on the BM is obtained. Finally, an analytical–numerical combination model, where both macrostructures and microstructures of cochlea are included, is established. The model not only vividly depicts the spatial helical body and biological materials of the cochlea but also reflects the fluid–solid coupling nonlinear motion of cochlear structures in the electrical environment. Thus, the active hearing mechanism of cochlea is revealed.
