Abstract
Recent demonstrations of room-temperature lasing in optically pumped GeSn show promise for future CMOS compatible lasers for Si-photonics applications. However, challenges remain for electrically pumped devices. Investigation of the processes that limit device performance is therefore vital in aiding the production of future commercial devices. In this work, a combined experimental and modelling approach is utilised to explore the dominant loss processes in current devices. By manipulating the band structure of functioning devices using high hydrostatic pressure techniques at low temperature, the dominant carrier recombination pathways are identified. This reveals that 93± 5% of the threshold current is attributable to defect-related recombination at a temperature, T = 85 K. Furthermore, carrier occupation of L-valley states (carrier leakage) is responsible for 1.1± 0.3% of the threshold current, but this sharply increases to 50% with a decrease of just 30 meV in the L- Γ separation energy. This indicates that thermal broadening of a similar order may reproduce these adverse effects, limiting device performance at higher temperatures. Temperature dependent calculations show that carrier occupation of indirect valley L-states strongly affects the transparency carrier density and is therefore very sensitive to the Sn composition, leading to an effective operational temperature range for given Sn compositions and strain values. Recommendations for future device designs are proposed based on band structure and growth optimisations.

Abstract
BACKGROUND It is vital to screen or develop alternative therapeutic drugs with higher curative characteristics and fewer side effects for the clinical treatment of gastric cancer. METHODS Gastric cancer cells were exposed to different auramycin G doses while determining the impact on cell viability, migration, and invasion. Then the antitumor effects of auramycin G, 5-fluorouracil (5-Fu) and their combination were evaluated. Furthermore, the molecular mechanisms of angiogenesis and lymphangiogenesis regulated by auramycin G and its analogs were investigated. RESULTS Auramycin G inhibited cell viability in a dose-dependent manner, with a 50% inhibitory concentration of 23.72 ± 6.36 mg/L and 32.54 ± 5.91 mg/L for AGS and MGC803 cells, respectively. The migration and invasion of gastric cancer cells were significantly inhibited by 10 mg/L auramycin G, which was consistent with the down-regulation of the VEGFR2-VEGFA-pPI3K-pAkt-pErk1 and VEGFR3-VEGFC-pPI3K-pAkt-pmTOR proteins. Notably, the average tumor weights were significantly reduced in both the auramycin G (2.21 ± 0.45 g) of 50 mg/kg body weight and auramycin G + 5-fluorouracil (5-Fu) groups (1.33 ± 0.28 g), compared with the control (3.73 ± 0.56 g). Considering that auramycin G decreased the growth of blood and lymphatic vessels while reducing the degree of tumor malignancy, it effectively suppressed tumors by regulating the angiogenic and lymphangiogenic pathways. CONCLUSION The present study confirmed that auramycin G displayed a prominent antitumor activity in gastric tumor models, both in vitro and in vivo. Moreover, it was confirmed that auramycin G played a specific role in certain gastric cancer cell types, while the mechanism was validated to be associated with angiogenesis- and lymphangiogenesis-related pathway suppression.

Abstract
Pneumocystis, an important opportunistic fungal pathogen that parasitizes in multiple mammalian lungs, may cause life-threatening Pneumocystis pneumonia (PCP) and even death among immunocompromised individuals. With the rapid development of high-throughput sequencing and multi-omics technologies, systematic comparative analyses of genome, transcriptome, and whole-genome sequencing results demonstrate that Pneumocystis is a type of obligate biotrophic fungi, and requires obtaining nutrition from hosts. In addition, sexual reproduction is an essential process for Pneumocystis survival, production and transmission, and asexual reproduction facilitates Pneumocystis survival, which provides new insights into understanding of the whole developmental process of Pneumocystis in the host lung and inter-host transmission of Pneumocystis. This review summarizes the advances in the reproduction mode of Pneumocystis and underlying mechanisms, which provides insights into prevention and treatment of PCP, notably for the prophylaxis against nosocomial transmission of PCP.

Abstract
The hierarchically nanostructured NiTe@CoxSy composites are constructed on a foamed nickel substrate by a two-step electrode preparation process. Structural characterization shows the dense growing of CoxSy nanosheets around NiTe nanorods forms a hierarchical nanostructure which possesses synergetic effects from both compositional and structural complementarity, more pathways for ion/electrolyte transport, richer redox active sites, and better conductivity. Thanks to the rational design of this hierarchical structure, NiTe@CoxSy delivers a high areal capacitance of 7.7F cm-2 at 3 mA cm-2 and achieves the improved capacitance retention of 97.9% after 10,000 cycles. Of particular importance is the successful fabrication of NiTe@CoxSy//activated carbon hybrid supercapacitors. This hybrid device has a wide operating voltage window, high areal energy density of 0.48 mWh cm-2 at 2.55 mW cm-2, impressive rate capability of 62.3% even after a 20-fold increase of the current density, and a 115.1% of initial capacitance retention after 15,000 cycles. Meanwhile, two tandem such hybrid devices can easily drive a pair of mini fans or light up a heart-like pattern assembled by 10 red LEDs. These experimental results not only demonstrate that the hierarchically nanostructured NiTe@CoxSy composites can serve as a prospective candidate electrode; but also develop a novel strategy about how to achieve high-performance stockpile equipment by rationale designing a desirable nanostructures.

Abstract
Objective: To investigate the effect of oxidative stress caused by heat exposure on the blood pressure increase of treadmill rats and the intervention of antioxidants. Methods: In June 2021, Twenty-four healthy SD male rats were randomly divided into four groups: normal temperature feeding, normal temperature treadmill, high temperature treadmill and high temperature treadmill supplementation with vitamin C groups, 6 rats in each group. The rats run on the platform in normal temperature or heat exposure environment for 30 min in the morning and in the afternoon daily, 6 days per week. The daily vitamin C supplement dose of high temperature treadmill supplementation with vitamin C group was 10 mg/kg. BP recordings were done at the end of the week. The rat vascular lipofuscin (LF) was detected by ELISA, the rat serum nitric oxide (NO) was detected by nitrate reductase method, the serum malondialdehyde (MDA) was detected by thibabituric acid method, the serum glutathione peroxidase (GPx) and superoxide dismutase (SOD) were detected by chemiluminescence method, and the serum catalase (CAT) was detected by ammonium molybdate method. The total antioxidant capacity (T-AOC) of serum was measured by iron reduction/antioxidant capacity method, and the content of nuclear erythroid 2-related factor 2 (Nrf2) in vascular tissue was measured by Western blot. The intra-group mean was compared by repeated measurement analysis of variance, and the inter-group mean was compared by single-factor analysis of variance and post-event LSD-t test. Results: Compared with the previous time point, the systolic BP and diastolic BP of the high temperature treadmill group were significantly increased at 7, 14 and 21 d, and decreased at 28 d which were higher than the initial level (P<0.05), and the systolic BP and diastolic BP values at each experimental time point were significantly higher than those of normal temperature treadmill group (P<0.001). The changes of thickening of the artery wall, no smoothing of the endodermis and irregular arrangement of muscle cells in high temperature treadmill group were observed. Compared with the normal temperature treadmill group, the content of MDA in serum, and LF in vascular tissue were significantly increased, the activities of SOD, CAT, T-AOC, the content of NO in serum, and the expression of Nrf2 in vascular tissue were significantly decreased in high temperature treadmill group (P<0.05). Compared with the high temperature treadmill group, the systolic BP and diastolic BP values at 7, 14, 21 and 28 d, the content of serum MDA and LF in vascular tissue were significantly decreased, the activities of CAT and T-AOC, and the expression of Nrf2 in vascular tissue significantly increased (P<0.05), the histopathological changes of the artery wall improved in high temperature treadmill supplementation with vitamin C group. Conclusion: Heat exposure has effect on oxidative stress, which may be related to the increase of BP. Vitamin C as an anti-oxidative enhancer can prevent those negative effects, which could alleviate the pathological changes of vessel intima in heat-exposed rats. And the Nrf2 may be a regulated factor to vascular protection.

Abstract
AIM To compare the accuracy of hand-held ultrasonography (US), mammography (MG), magnetic resonance imaging (MRI), and automated breast volume scanning (ABVS) in defining residual breast cancer tumour size after neoadjuvant therapy (NAT). MATERIALS AND METHODS Patients diagnosed breast cancer and who received NAT at the Breast Center, Peking University People's Hospital, were enrolled prospectively. Imaging was performed after the last cycle of NAT. The residual tumour size, intraclass correlation coefficients (ICCs), and receiver operating characteristic (ROC) to predict pathological complete response (pCR) were analysed. RESULTS A total of 156 patients with 159 tumours were analysed. ABVS had a moderate correlation with histopathology residual tumour size (ICC = 0.666), and showed high agreement among triple-positive tumours (ICC = 0.797). With 5 mm as the threshold, the coincidence rate reached 64.7% between ABVS and pathological size, which was significantly higher than that between US, MG, MRI, and pathological size (50%, 45.1%, 41.4%; p=0.009, p=0.001, p<0.001, respectively). For ROC analysis, ABVS demonstrated a higher area under the ROC curve, but with no statistical difference, except for MG (0.855, 0.816, 0.819, and 0.788, respectively; p=0.183 for US, p=0.044 for MG, and p=0.397 for MRI, with ABVS as the reference). CONCLUSIONS The longest tumour diameter on ABVS had a moderate correlation with pathological residual invasive tumour size. ABVS was shown to have good ability to predict pCR and would appear to be a potential useful tool for the assessment after NAT for breast cancer.

Abstract
OBJECTIVES Diet is an important modifiable factor for brain health and aging. Present study aimed to explore association of dietary quality with cognitive function and poor cognition in middle-aged and older adults participating in the China Health and Nutrition Survey (CHNS). DESIGN A longitudinal study with a twenty-year follow-up. SETTING AND PARTICIPANTS Data were drawn from the CHNS 1997, 2000, 2004, 2006, 2015 and 2018. Subjects aged 55 years and more who participated in at least two waves and had completed data on socio-demographics, lifestyle, disease history, anthropometrics, dietary measure and cognitive assessment were eligible in present study. METHODS Baseline diet were assessed by 3-day 24-hour dietary recalls and used to evaluate diet quality via China Elderly Dietary Guidelines Index 2022 (CDGI 2022-E). Cognitive function was examined using part items of the Telephone Interview for Cognitive Status-modified. Three-level linear mixed effects models and three-level mixed effects logistic regression models were performed to estimate the association between diet quality and cognitive function and odds of poor cognition, respectively. RESULTS At baseline, 4173 subjects with median age of 63.7 years were recruited. Median of CDGI 2022-E total score was 44.7. Median score of global cognition was 16.0, and the proportion of people with poor cognitive function was 13.9%. Difference in global cognitive score was observed by tertiles of CDGI 2022-E (p<0.05). Significant associations of high diet quality with increment in global cognitive score [β (95%CI): 0.704 (0.394~1.015)], composite cognitive z score [0.086 (0.045~0.128)] and standardized verbal memory score [0.221 (0.122~0.320)] were observed in total subjects. Consistent associations were also found in those below 65 years at baseline. The likelihood of poor cognition in the highest tertile of CDGI 2022-E decreased by 18% (95%CI: 0.698~0.965) relative to the lowest tertile group in total population. CONCLUSIONS High diet quality may be beneficial for improving cognitive function and delaying cognitive decline in Chinese middle-aged and older population.

Abstract
Surgical treatment of tumours in the anterior mandible and surrounding tissues may result in defects which can be restored by a fibula free flap. The upper airway may change during this process. The purpose of this retrospective study was to evaluate upper airway changes after fibula free flap reconstruction. A total of 37 patients who underwent anterior mandibulectomy and fibula free flap reconstruction between 2012 and 2020 were recruited. Patients with benign and malignant tumours involving the anterior mandible were included. Spiral computed tomography was performed 1 week preoperatively, 1 week postoperatively, and at> 1 year (range 12-23 months) after surgery. Cross-sectional areas and volumes of the upper airway were measured. Data were analysed by two-way analysis of variance. The upper airway in the malignant tumour group showed an increasing trend, especially at the soft palate and tongue base levels (P < 0.01). In the benign tumour group, the upper airway showed no significant changes. The location of the minimum cross-sectional area moved downwards in both groups, and the area increased in the malignant tumour group during long-term follow-up. Upper airway obstruction is less likely to occur in the long term after surgical resection of anterior mandible malignancies and fibula free flap reconstruction.

Abstract
OBJECTIVES This study aimed to examine the impact of deviant peer affiliation on migrant children's school adaptation in China and explore the mediating role of mental health in the relationship between deviant peer affiliation and school adaptation among migrant children. STUDY DESIGN This was a cross-sectional study based on secondary data. METHODS This study was based on the nationally representative China Education Panel Survey. Multiple linear regression models were used to quantify the relationship between deviant peer affiliation and school adaptation among 1,012 migrant children aged 12-17 years. Bootstrap test was used to evaluate the mediating effect of children's mental health. RESULTS Deviant peer affiliation showed a significant negative impact on the school adaptation of migrant children (β = -0.41, 95% confidence interval = -0.56 to -0.26). The relationship between deviant peer affiliation and school adaptation was partially mediated by children's mental health, resulting in an indirect effect of deviant peer affiliation on their school adaptation through their mental health (β = -0.05, 95% confidence interval = -0.09 to -0.03). The mediating role of mental health could explain 11.4% of the relationship between deviant peer affiliation and school adaptation. CONCLUSIONS Among migrant children, deviant peer affiliation showed unique effects on their school adaptation. Taking care of their mental health might help improve their school adaptation.

BACKGROUND Tumor growth rate (TGR), denoted as percentage change in tumor size per month, is a well-established indicator of tumor growth kinetics. The predictive value of early on-treatment TGR (EOT-TGR) for immunotherapy remains unclear. We sought to establish and validate the association of EOT-TGR with treatment outcomes in patients with advanced non-small-cell lung cancer (aNSCLC) undergoing anti-PD-1/PD-L1 (programmed cell death protein 1/programmed death-ligand 1) therapy. PATIENTS AND METHODS This bicenter retrospective cohort study included a training cohort, a contemporaneously treated internal validation cohort, and an external validation cohort. Computed tomography images were retrieved to calculate EOT-TGR, denoted as tumor burden change per month during a period between baseline and the first imaging evaluation after immunotherapy. Kaplan-Meier methodology and Cox regression analysis were conducted for survival analyses. RESULTS In the pooled cohort (n = 172), 125 patients (72.7%) were males; median age at diagnosis was 58 (range 28-79) years. Based on the training cohort, we determined the optimal cut-off value for EOT-TGR as 10.4%/month. Higher EOT-TGR was significantly associated with inferior overall survival [OS; hazard ratio (HR) 2.93, 95% confidence interval (CI) 1.47-5.83; P = 0.002], worse progression-free survival (PFS; HR 2.44, 95% CI 1.46-4.08; P = 0.001), and lower objective response rate (3.3% versus 20.9%; P = 0.040) and durable clinical benefit rate (6.7% versus 41.9%; P = 0.001). Results were reproducible in the two validation cohorts for OS and PFS. Among 43 patients who had a best response of progressive disease in the training cohort, those with high EOT-TGR had worse OS (HR 2.64; P = 0.041) and were more likely to progress due to target lesions at the first tumor evaluation (85.2% versus 0.0%; P <0.001). CONCLUSIONS Higher EOT-TGR was associated with inferior OS and immunotherapeutic response in patients with aNSCLC undergoing anti-PD-1/PD-L1 therapy. This easy-to-calculate radiologic biomarker may help evaluate the abilities of immunotherapy to prolong survival and assist in tailoring patients' management.

Abstract
Objective: To systematically evaluate the efficacy and safety of rock salt aerosol in the treatment of respiratory tract diseases. Methods: In June 2021, the clinical randomized controlled trial literatures of rock salt aerosol therapy for respiratory tract diseases were searched from CNKI, Wanfang, VIP, Cochrane Library, PubMed database and EMBASE database. Cochrane risk bias evaluation tool was used to evaluate risk bias, Revman 5.4 and Stata16 were used to conduct meta-analysis, TSA 0.9 was used to conduct sequential analysis of trials, and gradepro was used to evaluate evidence quality. Results: A total of 21 literatures were included. According to whether the subjects received rock salt aerosol therapy, they were divided into the experimental group (1125 people) and the control group (973 people) . Compared with the control group, the total clinical effective rate (RR=1.22, 95%CI: 1.15~1.29, P<0.001) , forced expiratory volume in one second (FEV(1)) (WMD=0.20, 95%CI: 0.09~0.31, P<0.001) , percentage of FEV(1) in the predicted value (FEV(1)%) (WMD=5.06, 95%CI: 3.47~6.65, P<0.001) , forced vital capacity (FVC) (WMD=0.22, 95% CI: 0.16~0.27, P<0.001) , maximum expiratory flow (PEF) (WMD=21.312, 95%CI: 9.189~33.435, P=0.004) of experimental group were higher. TSA test shows that the difference conclusions of total effective rate, FEV(1), FEV(1)%, FVC and PEF were reliable, but the conclusion of FEV(1)% needs to be treated with caution; Three literatures reported the adverse reactions in the experimental group; GRADE evidence quality evaluation showed 3 very low-quality evidences and 2 low-quality evidences. Conclusion: Rock salt aerosol therapy combined with conventional therapy has a certain effect on the treatment of respiratory tract diseases, which needs to be further confirmed by high-quality evidence.

Abstract
Objective: To identify prognostic factors for revitrectomy in patients who underwent pars plana vitrectomy (PPV) for complications with proliferative diabetic retinopathy (PDR). Methods: This study was a retrospective case-control study. Clinical data of PDR patients (290 eyes) at Peking University People's Hospital from December 2019 to December 2020 were retrospectively collected.According to the number of operations, patients were divided into two groups: single PPV group (227 eyes) and revitrectomy PPV group (63 eyes). Follow-up will be conducted up to 6 months postoperatively. The BCVA was compared before and after PPV between the two groups, and postoperative complications of revitrectomy PPV group were analyzed. Quantitative data are presented as medians [M (Q1, Q3)]. Results: The age of single PPV group patients was 55.0 (47.0, 63.0), and the age of revitrectomy PPV group patients was 49.0 (38.0, 57.0). This difference was statistically significant (P=0.027). The LogMAR visual acuity of two groups were 1.7 (1.0, 2.4) and 2.1 (1.4, 2.4) (P=0.026) preoperative; the visual acuity of single PPV group was 0.75 (0.43, 1.00) (P<0.001), and revitrectomy PPV group was 0.95 (0.60, 1.65) (P<0.001) at 6 months postoperative. The visual acuity improvement of single PPV group was better than revitrectomy PPV group (P=0.021). Age (P=0.043, OR=0.97, 95%CI: 0.95-1.00), preoperative BCVA (P=0.024, OR=1.82, 95%CI: 1.08-3.05), tractional retinal detachment (TRD) (P=0.033, OR=2.16, 95%CI:1.06-4.37), silicone oil tamponade (P=0.028, OR=0.48, 95%CI: 0.25-0.92) were prognostic factors of revitrectomy. Conclusion: Young age, low preoperative BCVA, TRD, and silicon oil tamponade were the potential prognostic factors of revitrectomy for PDR patients.

Abstract
Abstract
For larger containments and higher operation parameters, characteristics of the outside cooling of the PCCS are very important for the analysis on the containment integrity. A preliminary analysis was made and a four-step experimental method was used to numerically analyze the falling water film evaporation for the advanced passive containment. Then, the water flow stability along the outside wall of the containment was studied. The results fit well with those correlations without airflow when the air velocity is less than 5.0 m/s. However, when the air velocity is larger than 5.0 m/s, the influence of the air velocity on the water film will appear and the mean water film thickness will be thicker. Based on the prototype operation parameters, experimental studies were carried and the results were compared with the Dittus-Boelter correlation within the operation ranges. A modification factor was proposed for the conservative application of this correlation for nuclear safety analysis.

Abstract
Objective: To explore the clinical characteristics, treatment methods and outcomes of extramedullary plasmacytoma of the head and neck. Methods: A retrospective analysis was conducted on 10 cases with extramedullary plasmacytoma of the head and neck who were admitted to Henan Tumor Hospital from January 2005 to January 2020. Among the 10 patients, 6 were male and 4 were female. The average age at diagnosis was 56.3 years old (34-74 years old). Among them, 3 cases were located in the nasal cavity, 2 cases in the nasopharynx, 1 case in the sinuses, 2 cases in the larynx, 1 case in the oropharynx, and 1 case in the cervical lymph nodes. Treatments were administered according to tumor size and resection extent. Complete surgical excision (negative margins) was preferred, followed by adjuvant radiotherapy or radiotherapy alone. The clinical characteristics, diagnosis, treatment and prognosis of EMP were analyzed. Results: The patients' symptoms were not specific, frequently with local obstruction symptom and localized masses. All patients were confirmed pathologically as suffering from monoclonal plasmacytoma, with negative bone marrow biopsy and negative skeletal survey. Five patients received surgery, 3 received radiotherapy, and 2 received surgery with additional radiation. The follow-up time was 16-125 months, with a median of 92 months. Two patients developed into multiple myeloma. One patient who received radiotherapy after surgery relapsed after 7 years of follow-up and again received surgical treatment, with no evidence of second recurrence. The remaining patients had no recurrence or progression. Conclusion: Extramedullary plasmacytoma of the head and neck has a good prognosis. Surgical treatment can be considered for completely resectable lesions.

Abstract
Excessive microglial activation-mediated neuroinflammation is closely involved in the pathogenesis of several neurological diseases. CQMUH-011, as a novel adamantane sulfonamide compound, has been shown anti-inflammatory properties in activated macrophages (RAW264.7). However, the role of CQMUH-011 in microglial activation-induced neuroinflammation and neuroprotective properties has yet to be elucidated. In the present study, we investigated the potential effects and mechanisms of CQMUH-011 on lipopolysaccharide (LPS)-stimulated primary microglia in vitro and transient middle cerebral artery occlusion (t-MCAO)-induced acute cerebral ischemia/reperfusion (I/R) injury in vivo. The results demonstrated that CQMUH-011 significantly suppressed the production of tumor necrosis factor (TNF)-α and interleukin (IL)-1β by LPS-stimulated primary microglia. In addition, CQMUH-011 inhibited the proliferation of activated microglia by arresting the cell cycle at the G1/S phase accompanied by downregulating the expression of cell cycle regulatory proteins such as proliferating cell nuclear antigen (PCNA) and cyclin D1. CQMUH-011 was seen to induce apoptosis in activated microglia by regulating the expression of Bax and Bcl-2. Furthermore, CQMUH-011 markedly attenuated the protein expression of Toll-like receptor 4 (TLR4) and myeloid differentiation factor 88 (MyD88) as well as the phosphorylation levels of nuclear factor-kappa (NF-κB) subunit p65, inhibitory kappa B-alpha (IκBα), and mitogen-activated protein kinases (MAPKs) such as extracellular signal-regulated kinase (ERK) and p38 kinases. In vivo, CQMUH-011 administration significantly improved neurological function and infarct volume, and ameliorated the inflammatory cytokines and microglia amount around the injury site of mice. In conclusion, these results suggested that CQMUH-011 has a notable anti-inflammatory effect and protects mice from I/R injure. Thus, CQMUH-011 may be a candidate drug for the treatment of cerebral ischemia patients.

Abstract
Abstract
Many older people admitted to hospital are malnourished/at risk of malnourishment (30%), have swallowing problems (55%), are frail (25%), have sarcopenia (50%) or a combination of these. On admission to hospital frail older people are at significant risk of worsening nutritional status and prolonged hospital stay. Nutritional status should be identified, documented, food intake monitored and where appropriate they should be referred to the dietitian.
The question remains, do staff recognise that frail older people may not eat their food increasing their risk of poor nutrition and outcome.

Older people admitted to a ‘Frailty’ Ward were directly observed during lunchtime by WD. The Minimal Eating Observation Form –Version II (MEOF-II) was used to document how much they ate. Frailty status (CFS), presence of Sarcopenia (Sarc-F) and whether a referral to dietetics or speech and language therapy (SLT) was completed.
Results
39 patients were observed. Mean age was 82.38 years; median CFS 6 (3–8); median Sarc-F 4(0–9). Median MEOF II was 0 (0–5). Two patients were referred to dietetics and 4 to SLT. 7/40 (17,5%) were at high risk for undernutrition, a further 8/40(20%) were at moderate risk. 82% were severely frail, the remaining were mildly frail. 94% (16/17) exhibited sarcopenia. There was significant correlation between MEOF II and CFS (r = 0.4887, p = 0.00162); MEOFII and Sarc-F (r = 0.4395, p = 0.00512). There was correlation between CFS and Sarc-F (r = 0.80296, p < 0.00001). Only one (6%) was referred to the dietitian.
Conclusion
Frail older adults are often undernourished on admission to hospital. Nutritional intake is often poor with acute illness. Screening, observation and monitoring of nutritional intake should highlight concerns and needs for intervention. These study high lights that a significant number of older people are frail, fail to complete meals, are at significant risk of under nutrition, yet proactive intervention does not occur.

Abstract
Background:Tissue-resident memory T cells (TRM), are a recently identified T cells population featuring tissue localization and expression of markers of tissue homing, CD69 and CD103. Recently, the expansion of CD8+ TRMs and their involvement in the sialadenitis was described in a murine model of SS. However, CD4+ and CD8+ TRM’s functional relevance in pSS is still not fully understood, and the TRM therapeutic targeting unexplored.Objectives:The study aimed to address the role of CD4+ and CD8+ TRMs in the pathogenesis of pSS and to explore the therapeutic targeting of the tissue residency marker of TRM CD103.Methods:An animal model of experimental (ESS) obtained by immunization of female C57BL/6 mice (n=10) with salivary glands (SG) protein extract and Freund’s complete adjuvant used to investigate the dynamic of infiltration of SG by CD4+ and CD8+ TRMs, their frequency, and the impact of CD103 blockade. For the therapeutic intervention, at 10-weeks post-immunization, the salivary gland was cannulated via Wharton’s duct, and an anti-CD103 neutralizing antibody or vehicle-injected. The mice’s saliva flow rate was assessed, and SGs were analyzed by Flow-cytometry and immunohistochemistry (IHC).The frequency and localization of TRMs was analyzed in minor SG of sicca syndrome (nSS) and pSS patients (n=39) by flow cytometry and IHC. The expression of genes involved in the tissue retention of TRMs was assessed in SG by RT-PCR.Results:Upon the ESS progression, a significant progressive increase in CD45+CD103+ cells frequency was observed from 5wk to 20wk post-immunization (p<0.001), where the CD8+ were the most abundant, followed by CD4+. Consistently, CD103+CD8+ T cells were detected within the lymphocytic infiltration of SG from ESS mice. Sorted purified SG CD10+CD3+CD8+ T cells showed higher Granzyme B, TNF-alpha expression compared to CD103-CD3+CD8+ at both mRNA and protein levels. Notably, ESS mice treated with anti-CD103 showed improvement in salivary function (p<0.05) and reduced lymphocytic infiltrations measured as focus score (FS) (p<0.01) and area-fraction (p<0.01). Consistently, anti-CD103 treatment consistently reduced CD103+ cells and IFN-gamma+, Granzyme B+, and TNFa+ CD8+ cells. We next performed phenotypic analysis of CD45+CD103+ immune cells in the SG of pSS patients observing an increase in both with CD8+CD103+CD69+ and CD4+CD103+CD69+ (p<0.05). Finally, IHC showed that the expansion of TRMs in pSS salivary glands was accompanied by a down-regulation of E-cadherin glandular expression and their migration outside the epithelium in the context of inflammatory infiltrates. SG of patients with pSS showed a significant up-regulation of BLIMP1, KFL-2, and S1PR1 and down-regulation of ITGB2. CXCL9 and CXCL10, and IL-15 involved in the tissue recruitment and long-term survival of TRMs were significantly modulated in pSS salivary glands.Conclusion:TRM are expanded and activated in the SG of pSS and ESS, participating in the organization of tissue inflammation. Although the mechanisms behind this expansion are still not fully understood, CD103 could be a valuable novel therapeutic target to prevent lymphocytic infiltrations and glandular destruction in Sjogren syndrome.Disclosure of Interests:None declared

Abstract
OBJECTIVE To investigate the protective role of ulinastatin (UTI) on myocardial ischemia-reperfusion (I/R) injury in rats via endoplasmic reticulum stress (ERS)-induced apoptosis pathway. MATERIALS AND METHODS A total of 60 rats were randomly divided into normal group (n=20), myocardial I/R model group (model group, n=20), and myocardial I/R model+UTI treatment group (treatment group, n=20). The myocardial function indicators [creatinine (Scr) and creatine kinase (CK)] were detected. Enzyme-linked immunosorbent assay (ELISA) was performed to measure serum levels of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6), and matrix metalloproteinase-9 (MMP-9). Meanwhile, the contents of reactive oxygen species (ROS), superoxide dismutase (SOD), and malondialdehyde (MDA) in rat left ventricular tissues were determined by ELISA as well. The cardiac function indexes were determined via magnetic resonance imaging (MRI) and echocardiography (ECG). Terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-biotin nick end labeling (TUNEL) staining assay was carried out to detect the apoptosis of myocardial tissues. Additionally, the expression levels of endoplasmic reticulum stress and apoptosis genes were measured through quantitative Reverse Transcription-Polymerase Chain Reaction (qRT-PCR) assay and Western blotting analysis, respectively. RESULTS Serum levels of alanine aminotransferase (ALT), CK, and Scr in model group were significantly higher than those in normal group (p<0.05). Besides, rats in model group had significantly lowered SOD, ejection fraction (EF, %), and fractional shortening (FS, %) than those in normal group (p<0.05). In addition, remarkably increased contents of TNF-α, IL-6, MMP-9, MDA, and ROS, as well as higher left ventricular end-diastolic diameter (LVEDd) and left ventricular end-systolic diameter (LVESd) were observed in model group in comparison with normal group (p<0.05). TUNEL staining results revealed that there were more apoptotic cells in model group than that in the other two groups (p<0.05). Expression levels of cysteine aspartic acid-specific protease 12 (Caspase-12) and glucose-regulated protein 78 (GRP78) were evidently higher in model group than those in normal group (p<0.05), while the expression level of B-cell lymphoma 2 (Bcl-2) was clearly lower in model group than that in normal group (p<0.05). UTI treatment partially reversed the above expression changes (p<0.05). CONCLUSIONS UTI has a protective effect against myocardial I/R injury in rats by repressing the occurrence of ERS-induced apoptosis.

Abstract
OBJECTIVE To study the effect of RBMS3 on nucleus pulposus cells and its effect on the Wnt/β-catenin signaling pathway. PATIENTS AND METHODS We measured the expression of RBMS3 in human nucleus pulposus tissues with different degrees of degeneration. Recombinant human IL-1β is used to stimulate the degeneration of human nucleus pulposus cells. We used Wnt/β-catenin signaling pathway inhibitors and cell transfection to study the effect of RBMS3 on nucleus pulposus cells and its mechanism. RESULTS RBMS3 was less expressed in the nucleus pulposus tissue of people with higher degeneration degree. IL-1β reduced the expression of RBMS3 in nucleus pulposus cells. Overexpression of RBMS3 can promote the proliferation of nucleus pulposus cells and reduce the apoptosis and inflammation of cells. In addition, RBMS3 can reduce the expression of β-catenin and c-myc in nucleus pulposus cells, and inhibit the activity of the Wnt/β-catenin signaling pathway. CONCLUSIONS RBMS3 inhibits the Wnt/β-catenin signaling pathway, improves the proliferation ability of nucleus pulposus cells, inhibits their apoptosis and inflammation, and thus delays the degeneration of the intervertebral disc.

Abstract
Bone marrow-derived mesenchymal stem cells (BMSCs) have therapeutic potential for certain heart diseases. Previous studies have shown that stem cells inhibit cardiac hypertrophy; however, it is necessary to explore the mechanisms underlying this effect. This study aimed to investigate the possible mechanism underlying the inhibitory effect of BMSCs on cardiomyocyte hypertrophy. We induced cardiomyocyte hypertrophy in cultured rat cells through isoproterenol (ISO) treatment with or without BMSC coculture. A microarray was performed to analyze messenger RNA expression in response to ISO treatment and BMSC coculture. Pathway enrichment analysis showed that the expression of differential genes was closely related to the 5'-adenosine monophosphate-activated protein kinase (AMPK) signaling pathway and that the expression of forkhead box O 1 (FoxO1) was significantly increased in the presence of BMSCs. Furthermore, we determined the expression levels of p-AMPK/AMPK and p-FoxO1/FoxO1 by western blot analysis. The expression of p-AMPK/AMPK was upregulated, whereas that of p-FoxO1/FoxO1 was downregulated upon coculturing with BMSCs. The AMPK-specific antagonist Compound C inhibited the downregulation of p-FoxO1/FoxO1 induced by the BMSC coculture. Furthermore, treatment with the specific FoxO1 antagonist AS1842856 reduced the inhibitory effects of BMSCs on cardiomyocyte hypertrophy in vivo and in vitro. Our present study demonstrates the inhibition of cardiomyocyte hypertrophy by BMSCs, which occurs partly through the AMPK-FoxO1 signaling pathway.

Abstract
Objective: To compare the long-term clinical effect and imaging results of Bryan artificial cervical disc replacement (ACDR) and anterior cervical discectomy and fusion (ACDF) and to explore whether ACDR can reduce the occurrence of postoperative adjacent segment degeneration (ASD) in the treatment of degenerative cervical spondylosis. Methods: It was a retrospective study. Total of 60 patients with degenerative cervical spondylosis, who had received operations by Bryan ACDR (n=27) and ACDF (n=33) in the Third Hospital of Hebei Medical University between January 2005 and December 2009 were enrolled in this study. The Japanese Orthopedic Association (JOA) scores, neck disability index (NDI), visual analogue scale (VAS), Odom's scale, cervical range of motion (ROM), surgical segment ROM, heterotopic ossification (HO) and ASD were used to evaluate the clinical and radiologic results. The indices abovementioned were compared between the two groups. Results: The VAS, NDI and JOA scores at each follow-up node in both ACDR and ACDF group were all significantly improved when compared with those before operation (all P<0.05), but there was no significant differences between the two groups (all P>0.05). Of all, 88.9%(24/27) of patients in ACDR group and 84.8%(28/33) of patients in ACDF group achieved excellent or good results, however, there was no significant difference in Odom's scale between the two groups (P>0.05). At the last follow-up, the cervical ROM in ACDR group was 43.2°±8.8°, which was slightly lower than that before operation (45.7°±10.4°), the difference was not statistically significant (t=0.954, P=0.345); the surgical segment ROM in ACDR group was 5.9°±3.6°, which was significantly reduced when compared with that before operation (8.8°±3.4°, t=3.043, P<0.01). However at the last follow-up, the cervical ROM in ACDF group was 36.4°±8.4°, which was significantly reduced when compared with that before operation (43.9°±11.1°), the difference was statistically significant (t=3.095, P<0.01). Although, there was no significant difference in the cervical ROM between the two groups before operation (t=0.643, P=0.523), and the difference was statistically significant at the last follow-up (t=3.054, P<0.01). At the last follow-up, the incidence of HO in ACDR group was 92.6%, and the high-grade HO was 37.0%. The incidence of ASD in ACDR group was 39.5%, which was much lower than that in ACDF group (61.1%, χ(2)=4.462, P=0.035). Conclusion: At minimum follow-up of 10 years, Bryan ACDR achieves a satisfactory clinical effect consistent with ACDF. In terms of advantages, ACDR could maintain the ROM of cervical and retain the ROM of the surgical segment, which reduces the occurrence of ASD by preserving motion.

Abstract
OBJECTIVES Tuberculous pleurisy (TP) diagnosis remains difficult, with the sensitivity of Xpert MTB/RIF (Xpert) and mycobacterial culture (culture) only about 30-50%. We aimed to assess the diagnostic performance of a cell-free Mycobacterium tuberculosis DNA test (cf-TB) in pleural effusion for TP. METHODS Adults (≥18 years) with suspected TP presenting with pleural effusion were consecutively recruited, and pleural effusion specimens were prospectively collected in Beijing Chest Hospital, Beijing, China. After centrifuging pleural effusion, sediments were used for culture, Xpert and T-SPOT.TB assay, whereas supernatants were used for cf-TB and adenosine deaminase assay. The diagnostic performance was assessed against a composite reference standard. RESULTS From June 2015 to December 2018, we prospectively evaluated 286 adults with suspected TP. One hundred twenty-two participants were classified as definite TP based on the prespecified composite reference standard. The cf-TB produced a sensitivity of 79.5% (97/122, 95% confidence interval (CI) 72.4- 86.7) for definite TP, which was superior to Xpert (38.5% (29.9-47.2); 47/122; p < 0.001) and culture (27.1% (19.2-34.9); 33/122; p < 0.001). With pleural effusion Xpert and/or culture as the reference standard, cf-TB showed 96.6% (57/59, 95% CI 92.0-100.0) sensitivity, which was also significantly higher than Xpert (79.7%, 95% CI 69.4-89.9; 47/59; p 0.004) and culture (55.9%, 95% CI: 43.3-68.6; 33/59; p < 0.001). CONCLUSIONS The cf-TB clearly showed improved sensitivity compared with Xpert and culture. We recommend cf-TB as the first-line test for TP diagnosis.

Abstract
Objective: To evaluate the using value of FibroTouch and six serological models in detecting the degree of liver fibrosis in patients with chronic hepatitis B, in an attempt to provide reference for accurate diagnosis. Methods: Two hundred and fifty-eight cases with chronic hepatitis B admitted to Xixi Hospital of Hangzhou from September 1, 2015 to September 1, 2017 were selected. All patients underwent liver histopathological examination and FibroTouch measurement to determine liver stiffness (LSM). Serum biochemical parameters were detected and the scoring values of six serological models were calculated. SAS 9.4 statistical software was used for statistical analysis, and the correlation between FibroTouch and the six serological models was analyzed by Spearman correlation. The diagnostic value of FibroTouch and six serological models was analyzed by receiver operating characteristic curve (ROC) based on liver histopathological findings. Results: The median LSM of 258 cases with chronic hepatitis B was 9.4 (6.5-13.8) kPa. In the six serological models, the median value of aspartate transaminase to platelet ratio index (APRI), FIB-4 index, S-index, Forn's index, PRPindex, and FIB-5 were 0.42 (0.28-0.62), 1.27 (0.78-2.03), 0.11 (0.07-0.20), 6.95 (5.89-8.51), 0.000 8 (0.000 6-0.000 9),and 38.59 (36.28-40.97). FibroTouch had positive correlation with APRI, FIB-4, S-index, Forn's index, PRP, fibrosis stage (r= 0.73,P< 0.001) and inflammation grade, and had negative correlation with FIB-5, and both had statistical significance. The area under curve (AUC) of FT-LSM at S≥2, S≥3, S = 4 were 0.89, 0.90 and 0.85, respectively, which was significantly higher than serological models (P< 0.001). The AUC of S-index model at S≥2, S≥3, S = 4 were higher than other five serological models. Conclusion: The diagnostic performance of FibroTouch is significantly better than serological model. S-index model has the best diagnostic performance in the six serological models, and the combination of S-index and FT-LSM may better diagnose the grading of liver fibrosis, and thus can be applied and promoted in clinic.

Abstract
The aim of this paper was to introduce a simple and effective method to aid in isolation and stabilization of Dupuytren cords for collagenase injection. Tongue depressors were used to isolate and stabilize the cord during the injection procedure. The area to be injected was sterilely prepared. An assistant was then directed to place a tongue depressor on both sides of the cord. A total of 35 patients with Dupuytren disease were treated. Follow-up lasted two years. Post-operative Disabilities of the Arm, Shoulder and Hand (DASH) scores was 4±2. Health-related quality of life measured with the EQ-5D index was 0.89±0.4. Recurrence rates of metacarpophalangeal joint and proximal interphalangeal joint were 11% and 14% respectively, using a flexion contracture of 20° to define recurrence. Collagenase treatment using a modified injection method with the aid of tongue depressors are a safe, effective way to treat Dupuytren contractures of the fingers. The technique can isolate the cord, which improves visualization of the cord. It may allow improved accuracy with needle placement and helps to decrease the complications and recurrence.

Abstract
OBJECTIVE To find variations in Chinese obesogenic environmental priorities from 2000 to 2011, predict spatiotemporal distribution of obesity prevalence aged 7-17 years in 31 provinces, and provide foundations for policy-makers to reduce obesity in children and adolescents. METHODS Based on data examination of provincial obesity prevalence aged 7-17 years from three rounds of China Health and Nutrition Surveys (in 9 [2000], 9 [2006], and 12 [2011] provinces) and corresponding years' environments in 31 provinces from China Statistical Yearbooks and other sources, 12 predictors were selected. We used 30 surveyed provinces in three rounds as training samples to fit three analytic models with partial least-square regressions and prioritized predictors by variable importance projection to find variations. And fitted a spatiotemporal prediction model with Bayesian analysis to infer in space-time. RESULTS Variations of obesogenic environmental priorities were found at different times. A Bayesian spatiotemporal prediction model with deviance information criterion of 155.60 and statistically significant (P < 0.05) parameter estimates of intercept (-717.0400, 95% confidence intervals [CI]: -1186.0300, -248.0480), year (0.3584, CI: 0.1245, 0.5924), square of food industry level (0.0003, CI: 0.0002, 0.0004), and log (healthcare) (5.3742, CI: 2.5138, 8.2347) was optimized. Totally inferred average obesity prevalence among children and adolescents were 2.23%, 5.11%, 10.77%, 12.20%, 13.99%, and 17.58% in 31 provinces in China in 2000, 2006, 2011, 2015, 2020, and 2030, respectively. Obesity in north and east of China clusters on predicted maps. CONCLUSIONS Obesity prevalence in children and adolescents in China is rapidly increasing, growing at 0.3584% annually from 2000 to 2011. From longitudinal observation, prevalence was significantly influenced by food industry ("Amplifier") and healthcare service ("Balancer"). Targeted interventions in north and east of China are pressing. Further researches on the mechanisms underlying the influence of food industry, healthcare service, and so on in children and adolescents are needed.

Abstract
BACKGROUND Little is known about the sociodemographic and clinical characteristics of adverse drug events (ADEs) in patients with neurodevelopmental disorders (NDD). OBJECTIVE The objective of this study was to describe and compare the demographic details of people with and without NDD hospitalised due to ADEs. METHODS The all-inclusive New South Wales Admitted Patient Data Collection from 2001 to 2014 was employed to identify ADE-related hospitalisations in patients with NDD using the International Classification of Diseases 10th revision Australian modification codes. We derived case sets specific to different clinical groups and patient characteristics and compared proportional differences between patients with and without intellectual disability using chi squared tests. RESULTS A total of 2173 patients with NDD were admitted for acute care of ADEs, accounting for 0.7% of all ADE-related hospitalisations. Hospitalised ADEs among patients with NDD increased by twofold over the 14-year study period. Psychotropic medications and opioid analgesic medications were leading causes of ADE-related hospitalisations in patients with NDD. Compared with their counterparts, patients with NDD were younger, experienced more socio-economic disadvantage and less private insurance coverage, suffered with less severe but different co-morbid clinical conditions and incurred more challenges in the acute hospital care setting. CONCLUSION Although the pattern of ADE-related hospitalisations in patients with NDD differed from that in patients without NDD, there is a lack of targeted healthcare programmes to meet their special needs. This study suggests the need for countermeasures in primary healthcare settings to reduce the burden of ADEs in this vulnerable group.

Abstract
This study was designed to investigate the neuroprotective effects of baicalein and the effect of the cortical 12/15-lipoxygenase (12/15-LOX) pathway on diabetic cognitive dysfunction. Our results showed that spatial learning and memory ability, as well as cortex neurons, were significantly impaired after the onset of diabetes. The fasting blood glucose and random blood glucose levels in the model group were significantly higher than those in the normal group. The levels of TG and TC in the plasma of the model group were significantly increased, but there was no significant difference in the LDL level. The insulin content in the plasma of diabetic rats was significantly lower than that of the normal group. The levels of inflammatory factors and 12(S)-HETE were significantly increased in diabetic rats, as were the protein expression levels of cPLA2, 12/15-LOX, p38MAPK, phospho-p38MAPK, caspase-3, caspase-9 and Aβ1-42; by contrast, protein expression of Bcl-2 was significantly decreased. Administration of baicalein was shown to improve the spatial learning and memory ability and significantly decrease the levels of inflammatory cytokines. However, baicalein did not significantly influence the levels of blood glucose, lipids or insulin in rats. Baicalein treatment significantly protected diabetes rats from neuron death; significantly attenuated the overexpression of cPLA2, 12/15-LOX, p38MAPK, phospho-p38MAPK, caspase-3, caspase-9 and Aβ1-42; and upregulated the expression of Bcl-2. These findings suggest that baicalein improves the cognitive function of diabetic rats by directly acting in the brain rather than by regulating the levels of blood glucose, lipids or insulin. In addition, baicalein can protect rat cortical neurons from damage caused by diabetes via inhibiting the 12/15-LOX pathway and relieving inflammation and apoptosis of the central nervous system.

Abstract
The present study was designed to observe the effect of COX2/PGD2-related autophagy on brain injury in type 2 diabetes rats. The histopathology was detected by haematoxylin–eosin staining. The learning and memory functions were evaluated by Morris water maze. The levels of insulin and PGD2 were measured by enzyme-linked immunosorbent assay. The expressions of COX2, p-AKT(S473), p-AMPK(T172), Aβ, Beclin1, LC3BII, and p62 were measured by immunohistochemistry and Western blotting. In model rats, we found that the body weight was significantly decreased, the blood glucose levels were significantly increased, the plasma insulin content was significantly decreased, the learning and memory functions were impaired and the cortex and hippocampus neurons showed significant nuclear pyknosis. The levels of COX2, p-AKT(S473), PGD2, Aβ, Beclin1 and p62 were significantly increased, whereas the expression of p-AMPK(T172) and LC3BII was significantly decreased in the cortex and hippocampus of model rats. In meloxicam-treated rats, the body weight, blood glucose and the content of plasma insulin did not significantly change, the learning and memory functions were improved and nuclear pyknosis was improved in the cortex and hippocampus neurons. The expression of p-AMPK(T172), Beclin1 and LC3BII was significantly increased, and the levels of COX2, p-AKT(S473), PGD2, Aβ, and p62 were significantly decreased in the cortex and hippocampus of meloxicam-treated rats. Our results suggested that the inhibition of COX2/PGD2-related autophagy was involved in the mechanism of brain injury caused by type 2 diabetes in rats.

Abstract
This study investigated the surgical outcomes and accuracy of computer-assisted osteotomy guides and pre-bent titanium plates in the treatment of patients with facial asymmetry. Thirteen patients with facial asymmetry undergoing bimaxillary orthognathic surgery were included. Virtual simulation of Le Fort I osteotomy, sagittal split ramus osteotomy, and genioplasty, if needed, was conducted on the preoperative three-dimensional model. Computer-assisted osteotomy guides and pre-bent titanium plates were produced and used in the actual operation. The postoperative outcome was assessed for facial symmetry and surgical accuracy. All patients were followed up for at least 18 months and their level of satisfaction was investigated. Use of the computer-assisted osteotomy guides and pre-bent titanium plates was successful in all patients. Maxillary canting, mandibular ramus inclination, and mandibular length were corrected on both sides postoperatively. Superimposition of the surgical simulation and postoperative images demonstrated favourable accuracy. Quantitative analysis revealed a mean linear difference of <0.60mm in the maxilla and 1.57mm in the mandible. All patients were satisfied with the surgical outcome; there were no complications or cases of relapse during follow-up. The application of computer-assisted osteotomy guides and pre-bent titanium plates achieved favourable outcomes and accuracy, improving planning for the correction of facial asymmetry.

Abstract
We aimed to describe the treatment of comminuted fractures of the base of the thumb metacarpal using a cemented bone-K-wire frame. Between March 2010 and January 2016, 41 fractures of the base of the thumb were treated using a cemented bone-K-wire frame. The mean age of the patients was 34 years. The patients' history included a fall onto the hand in 7 cases, direct trauma in 31 cases, and polytrauma with an unclear mechanism of injury in 3 cases. At the final follow-up, hand grip and pinch strength were measured using a dynamometer. All measurements were compared with those of the opposite hand. The patients were assessed functionally using the Smith and Cooney score.All K-wires were left in place until the bone healed. Bone healing was achieved in all thumbs in an average of 5.2 weeks. Follow-up averaged 27 months. The mean hand pinch and grip strength was 8.7 kg ± 2.4 kg and 38.4 kg ± 5.9 kg, respectively. The mean measurements on the opposite side were 9.2 kg ± 2.5 kg and 40.2 kg ± 6.6 kg, respectively. Based on the Smith and Cooney score, we obtained an average score of 87 ± 9.3, with 25 excellent, 9 good, and 2 fair results. The cemented bone-K-wire frame is an external fixator alternative that can be used for treating comminuted intra-articular fractures of the base of the thumb metacarpal. The system is cheap, easy to apply, and provides rigid fixation, resulting in good functional recovery.

Abstract
Bacillus is widely used in the livestock industry. This study was designed to evaluate the effects of probiotic Bacillus amyloliquefaciens SC06 (Ba), originally isolated from soil, in piglets diet as an alternative to antibiotics (aureomycin), mainly on intestinal epithelial barrier and immune function. Ninety piglets were divided into three groups: G1 (containing 150 mg/kg aureomycin in the diet); G2 (containing 75 mg/kg aureomycin and 1×108 cfu/kg Ba in the diet); G3 (containing 2×108 cfu/kg Ba in the diet without any antibiotics). The results showed that, compared with the antibiotic group (G1), villus length, crypt depth and villus length/crypt depth ratio of intestine significantly increased in the G2 and G3 groups. In addition, intestinal villi morphology, goblet-cell number, mitochondria structure and tight junction proteins of intestinal epithelial cells in G2 and G3 were better than in G1. The relative gene expression of intestinal mucosal defensin-1, claudin3, claudin4, and human mucin-1 in G3 was significantly lower, while the expression of villin was significantly higher than in the antibiotic group. Probiotic Ba could significantly decrease serum interferon (IFN)-α, IFN-γ, interleukin (IL)-1β, and IL-4 levels, whereas increase tumour necrosis factor (TNF)-α and IL-6 secretion. Ba could also significantly decrease cytokines TNF-α, IFN-γ, IL-1β, and IL-4 level in liver, whereas it significantly increased IFN-α. Furthermore, replacing antibiotics with Ba also significantly down-regulated gene expression of TNF and IL-1α in intestinal mucosa, but up-regulated IL-6 and IL-8 transcription. Dietary addition of Ba could significantly reduce the gene expression of nuclear factor kappa beta (NFκB)-p50 and Toll-like receptor (TLR)6, while there was no significant difference for that of myeloid differentiation primary response 88, TNF receptor-associated factor-6, nucleotide-binding oligomerisation domain-containing protein 1, TLR2, TLR4, and TLR9. Taken together, our findings demonstrated that probiotic Ba could increase the intestinal epithelial cell barrier and immune function by improving intestinal mucosa structure, tight junctions and by activating the TLRs signalling pathway.
