Abstract
BACKGROUND Onradivir (ZSP1273) is a novel anti-influenza A virus inhibitor. Preclinical studies show that onradivir can inhibit influenza A H1N1 and H3N2 replication and increase the survival rate of infected animals. In this study, we aimed to evaluate the safety and efficacy of three onradivir dosing regimens versus placebo in outpatients with acute uncomplicated influenza A virus infection. METHODS We did a multicentre, double-blind, randomised, placebo-controlled, phase 2 trial at 20 clinical sites in China. Eligible participants were adults (18-65 years) with an influenza-like illness screened by rapid antigen testing at the first clinical visit, had the presence of a fever (axillary temperature ≥38·0°C), and had the presence of at least one moderate systemic and one respiratory symptom within 48 h of symptom onset. Patients were excluded if they were pregnant, allergic to onradivir, or had received any influenza antiviral medication within 7 days before enrolment. Participants were randomly assigned (1:1:1:1) into four groups by an interactive web response system: onradivir 200 mg twice per day group, onradivir 400 mg twice per day group, onradivir 600 mg once per day group, and a matching placebo group. A 5-day oral treatment course was initiated within 48 h after symptoms onset. The primary outcome was the time to alleviate influenza symptoms in the modified intention-to-treat population. Safety was a secondary outcome. We evaluated the patients' self-assessed severity of seven influenza symptoms on a 4-point ordinal scale, and the treatment-emergent adverse events in all patients. This trial is registered with ClinicalTrials.gov, number NCT04024137. FINDINGS Between Dec 7, 2019, and May 18, 2020, a total of 205 patients were screened; of whom, 172 (84%) were randomly assigned to receive onradivir (n=43 in the 200 mg twice per day group; n=43 in the 400 mg twice per day group; and n=43 in the 600 mg once per day group), or placebo (n=42). Median age was 22 years (IQR 20-26). All three onradivir groups showed decreased median time to alleviate influenza symptoms (46·92 h [IQR 24·00-81·38] in the 200 mg twice per day group, 54·87 h [23·67-110·62] in the 400 mg twice per day group, and 40·05 h [17·70-65·82] in the 600 mg once per day) compared with the placebo group (62·87 h [36·40-113·25]). The median difference between the onradivir 600 mg once per day group and the placebo group was -22·82 h (p=0·0330). The most frequently reported treatment-emergent adverse event was diarrhoea (71 [42%] of 171), ranging from 33-65% of the patients in onradivir-treated groups compared with 10% in the placebo group; no serious adverse events were observed. INTERPRETATION Onradivir showed a safety profile comparable to placebo, as well as higher efficacy than placebo in ameliorating influenza symptoms and lowering the viral load in adult patients with uncomplicated influenza infection, especially the onradivir 600 mg once per day regimen.

Abstract
Background Leritrelvir is a novel α-ketoamide based peptidomimetic inhibitor of SARS-CoV-2 main protease. A preclinical study has demonstrated leritrelvir poses similar antiviral activities towards different SARS-CoV-2 variants compared with nirmatrelvir. A phase 2 clinical trial has shown a comparable antiviral efficacy and safety between leritrelvir with and without ritonavir co-administration. This trial aims to test efficacy and safety of leritrelvir monotherapy in adults with mild-to-moderate COVID-19. Methods This was a randomised, double-blind, placebo-controlled, multicentre phase 3 trial at 29 clinical sites in China. Enrolled patients were from 18 to 75 years old, diagnosed with mild or moderate COVID-19 and not requiring hospitalization. Patients had a positive SARS-CoV-2 nucleic acid test (NAT) and at least one of the COVID-19 symptoms within 48 h before randomization, and the interval between the first positive SARS-CoV-2 NAT and randomization was ≤120 h (5 days). Patients were randomly assigned in a 1:1 ratio to receive a 5-day course of either oral leritrelvir 400 mg TID or placebo. The primary efficacy endpoint was the time from the first dose to sustained clinical recovery of all 11 symptoms (stuffy or runny nose, sore throat, shortness of breath or dyspnea, cough, muscle or body aches, headache, chills, fever ≥37 °C, nausea, vomiting, and diarrhea). The safety endpoint was the incidence of adverse events (AE). Primary and safety analyses were performed in the intention-to-treat (ITT) population. This study is registered with ClinicalTrials.gov, NCT05620160. Findings Between Nov 12 and Dec 30, 2022 when the zero COVID policy was abolished nationwide, a total of 1359 patients underwent randomization, 680 were assigned to leritrelvir group and 679 to placebo group. The median time to sustained clinical recovery in leritrelvir group was significantly shorter (251.02 h [IQR 188.95-428.68 h]) than that of Placebo (271.33 h [IQR 219.00-529.63 h], P = 0.0022, hazard ratio [HR] 1.20, 95% confidence interval [CI], 1.07-1.35). Further analysis of subgroups for the median time to sustained clinical recovery revealed that (1) subgroup with positive viral nucleic acid tested ≤72 h had a 33.9 h difference in leritrelvir group than that of placebo; (2) the subgroup with baseline viral load >8 log 10 Copies/mL in leritrelvir group had 51.3 h difference than that of placebo. Leritrelvir reduced viral load by 0.82 log10 on day 4 compared to placebo. No participants in either group progressed to severe COVID-19 by day 29. Adverse events were reported in two groups: leritrelvir 315 (46.46%) compared with placebo 292 (43.52%). Treatment-relevant AEs were similar 218 (32.15%) in the leritrelvir group and 186 (27.72%) in placebo. Two cases of COVID-19 pneumonia were reported in placebo group, and one case in leritrelvir group, none of them were considered by the investigators to be leritrelvir related. The most frequently reported AEs (occurring in ≥5% of participants in at least one group) were laboratory finding: hypertriglyceridemia (leritrelvir 79 [11.7%] vs. placebo 70 [10.4%]) and hyperlipidemia (60 [8.8%] vs. 52 [7.7%]); all of them were nonserious. Interpretation Leritrelvir monotherapy has good efficacy for mild-to-moderate COVID-19 and without serious safety concerns.

Abstract
Stress is one of the most important factors in metal-to-metal sealing. In this paper, two methods (theoretical and empirical) were adopted to calculate the normal stress of the brass sealing surfaces against different ultrahigh pressure liquid. The theoretical formula was derived in terms of force balance, and the empirical formula was obtained by polynomial curve fitting, which the fitted data were from simulated results; besides, the results calculated using the empirical formula agree well with the results by theoretical formula. Meanwhile, the equivalent stresses of the brass seal, normal stress and contact stress on the brass seal surfaces were simulated by finite element method, and the simulated results indicated these stresses are increased with the increase of liquid pressure, and the maximum stresses always appear on the tip of the brass seal.

Abstract
Background Breast cancer (BRCA) is the most common malignant tumor in the world. Because of its substantial heterogeneity, its clinical treatment is faced with various problems. Only a small number of patients can benefit from the treatment of immune checkpoint inhibitor (ICI). Costimulatory molecule signature (CMS) plays an essential role in T cell activation and antitumor immune response. Previous studies found that CMS is associated with prognosis-related immune response markers, suggesting that CMS may be a potential therapeutic target. However, the research on their function in BRCA subtype is still inadequate. Our study aims to analyze CMS in BRCA and establish an effective prognostic model. Methods We extracted 1,222 messenger RNA (mRNA) samples of 1,110 patients registered in the BRCA cohort of The Cancer Genome Atlas (TCGA), including 1,109 tumor tissue mRNA samples and 113 standard tissue samples for model construction and verification. The prognostic significance was determined by least absolute shrinkage and selection operator (LASSO)-Cox proportional hazard regression, which showed that the overall survival (OS) of the high-risk group was shorter than that of the low group (P<0.01). Results Although the CMS prognostic model can predict the prognosis well, the receiver operating characteristic (ROC) prediction results were unsatisfactory. The reason for this may be the heteromorphism of BRCA, so we divided the cases into four subtypes according to the PAM50 (PAM50Call_RNAseq) in clinical information. The same method was used to construct the model in the four subtypes and verify the effect of each subtype prognostic model. Conclusions The results showed that the submodels constructed in this study can be used to evaluate the prognosis of each subtype.

Abstract
Nuclear pore membrane protein 121 (POM121) is a part of the nuclear pore complex, which regulates intracellular signaling and maintains normal cellular functions. However, the role of POM121 in gastric cancer (GC) remains unclear. Quantitative real-time polymerase chain reaction was performed to detect POM121 mRNA in 36 pairs of GC and adjacent non-tumor tissues. POM121 protein expression was determined by immunohistochemistry in 648 GC tissues and 121 normal gastric tissues. Connections between POM121 levels, clinicopathological parameters, and the prognosis of GC patients were explored. The influence of POM121 on proliferation, migration, and invasion was detected in vitro and vivo. The mechanism underlying the involvement of POM121 in GC progression was demonstrated via bioinformatics analysis and Western blot. Both the mRNA and protein levels of POM121 in GC tissues were higher than those in normal gastric tissues. High POM121 expression in GC was associated with deep invasion, advanced distant metastases and TNM stage, and positive HER2 expression. A negative connection was found between POM121 expression and the overall survival (OS) of GC patients. Downregulation of POM121 inhibited the proliferation, clone formation, migration, and invasion of GC cells, and overexpression of POM121 showed the opposite trend. POM121 promoted the phosphorylation of PI3K/AKT pathway and increased the expression of MYC. In conclusion, this study suggested that POM121 has the potential to act as an independent prognostic factor for GC patients.

Abstract
Abstract
Background
Hyponatremia serves as a well established predictor of mortality for advanced heart failure (1). The aim of this study is to reassess the association between hyponatremia and in-hospital outcomes in patients with acute decompensated heart failure (ADHF) by using a nationally representative sample.
Methods
We queried the National Inpatient Sample (NIS) database collected between 2016 and 2018 to identify patients with a primary diagnosis of HF and stratified the cohort on the basis of presence or absence of hyponatremia. The outcomes of interest included in-hospital mortality, common associated complications and usage of circulatory support.
Results
Among 727,629 hospital admissions for HF, 72,824 (10%) of them had an additional diagnosis of hyponatremia. The hyponatremia cohort appeared similar in age and had similar rates of Charlson comorbidity index greater than 4 (71 years vs 72 years and 33% vs 35%, respectively) compared to the non-hyponatremia cohort. The comorbidities more prevalent in patients with hyponatremia included: hypothyroidism (17% vs 21%, p<0.001), liver disease (4% vs 11%, p<0.001) and anemia (31% vs 42, p<0.001). By contrast, dyslipidemia, chronic obstructive pulmonary disease, chronic kidney disease, hypertension, diabetes mellitus, obesity, smoking status and supplemental oxygen use were comparable in both groups. ADHF patients with hyponatremia did not have higher odds of in-hospital mortality (aOR: 1.08, 95% CI: 0.98–1.19, p=0.138) when adjusted for comorbidities. Nevertheless, patients with hyponatremia had an adjusted increase in mean hospital charges of 14,731 US$ (95% CI: 11065–18397, p<0.001), length of stay by 2.6 days (95% CI: 2.5–2.8, p<0.001), usage of intra-aortic balloon pump (aOR: 1.97, 95% CI: 1.50–2.59, p<0.001) and left ventricular assist device (aOR: 2.21, 95% CI: 1.639–2.98, p<0.001), and higher incidence of acute renal failure (aOR: 1.13, 95% CI: 1.08–1.189, p<0.001) and cardiogenic shock (aOR: 1.58, 95% CI: 1.42–1.76, p<0.001) in comparison to patients without hyponatremia.
Conclusion
Multiple clinical variables excluded in the NIS dataset could have impacted the primary outcome. Clinicians who observe hyponatremia in ADHF patients should stay wary of potential side effects and maintain a low threshold to escalate care.

Abstract
BACKGROUND Cesarean delivery (CD), is increasingly recommended as a mode of delivery that prevents the anal incontinence (AI) that arises in some women after vaginal delivery (VD). The assessment of the efficacy of CD in this regard was the subject of this systematic review. METHODS Searches were conducted in Medline, EMBASE and the Cochrane Library. Both randomized (RCTs) and non-randomized trials (NRTs) comparing the risk of sustained fecal and/or flatus incontinence after VD or CD were sought from 1966 to 1 January, 2019. Studies were eligible if they assessed AI more than 6 months after birth, and had statistical adjustment for at least one of the three major confounders for AI: age, maternal weight or parity. In addition, each study was required to contain more than 250 participants, more than 50 CDs and more than 25 cases of AI. Data after screening and selection were abstracted and entered into Revman for meta-analysis. Analyses were done for combined fecal and flatus incontinence (comAI), fecal incontinence (FI), gas incontinence (GI), CD before or during labor, time trend of incontinence after delivery, assessment of both statistical and clinical heterogeneity, parity and late incident AI. RESULTS Out of the 2526 titles and abstracts found, 24 eligible studies were analyzed, 23 NRTs and one RCT. These included women with 29,597 VDs and women with 6821 CDs. Among the primary outcomes, VD was found not to be a significant predictor of postpartum comAI compared to CD in 6 studies, incorporating 18,951 deliveries (OR = 0.74; 0.54-1.02). VD was also not a significant predictor of FI in 14 studies, incorporating 29,367 deliveries, (OR = 0.89; 0.76-1.05). VD was not a significant predictor of GI in six studies, incorporating 6724 deliveries (OR = 0.96; 0.79-1.18). The strength of the grading of recommendations, assessment, development and evaluations (GRADE) evidence for each of these was low for comAI and moderate for FI and GI (upgrade for lack of expected effect). Time trend FI showed incontinence at 3 months often resolved at 1 year. Other secondary analyses assessing parity, delayed incidence of FI, clinical and statistical heterogeneity, spontaneous VD only, late risk of incidence of AI, and CD in or prior to labor all had similar results as in the primary outcomes. CONCLUSIONS There are three components of pelvic floor dysfunction that are thought to be caused by VD and hopefully prevented by CD: AI, urinary incontinence and pelvic floor prolapse. Of these, AI was not found to be reliably prevented by CD in this review.

Abstract
BACKGROUND: Acute pesticide poisoning has long been a serious problem as a method of suicide worldwide. This poisoning is a highly fatal condition that requires a rapid and precise diagnosis for adequate treatment. However, various studies on mortality predictor factors have been insufficient for whole pesticide treatments. We hypothesized that the initial plasma anion gap (AG) and base deficit (BD) are reliable prognostic factors. METHODS: A retrospective study analyzed 561 patients with a diagnosis of acute pesticide poisoning between January 1, 2014 and June 30, 2017. The initial AG and BD values were divided into quartiles according to the number of patients. Survival at 30 days from admission was estimated using the Kaplan-Meier survival analysis. Receiver-operator characteristic (ROC) curves were drawn, and the areas under the curve for AG and BD for mortality were calculated. RESULTS: Fifty-eight (10.3%) of 561 patients died within 30 days. The highest AG quartile (>22 mEq/L) was associated with an increased risk of 30-day hospital mortality. Compared to patients with an AG less than 14.7 mEq/L, these patients had a 4.18-fold higher risk of 30-day hospital mortality and the highest BD quartile (>7.9 mEq/L) was associated with an increased risk of 30-day hospital mortality. Compared to patients with a BD less than 1.4 mEq/L, these patients had 2.23-fold higher risk of 30-day hospital mortality. The areas under the ROC for AG and BD curve were 0.699 and 0.744, respectively. CONCLUSIONS: Initial high AG and BD values could predict mortality and require precise intensive care.

Abstract
Introduction The aim of this study is to construct clinical prediction models to predict emergency department (ED) return visit following initial discharge for acute pyelonephritis (APN) and the need for hospital re-admission upon ED return visits. Method A retrospective analysis included 1250 discharged women with APN. Independent risk factors for revisit and subsequent admission after revisit were determined by multivariate analysis, and a prediction model for revisit and subsequent admission after revisit was constructed. Results Independent risk factors for revisit were nausea (2 points), age ≥ 65 years (2 points), C-reactive protein >20 mg/dL (2 points), serum albumin <3.3 g/dL (3 points) and urine white blood cell count ≥ 30/high power field (2 points). Re-visit risk scores were categorised to five groups and the re-visit rate was 5.4%, 8.6%, 12.2%, 19.1% and 43.8%, respectively, showing an area under curve (AUC) of 0.62. Risk factors for subsequent admission after revisit were vomiting (1 point), hypertension (2 points), serum creatinine <1.5 mg/dL (2 points), C-reactive protein >20 mg/dL (2 points) and serum albumin <3.3 g/dL (4 points). The subsequent admission after revisit risk scores were classified to three groups and subsequent admission after revisit rate was 3.5%, 15.0%, and 38.2%, respectively. Conclusion The developed model can identify a group of patients at high risk for a return visit and for requiring subsequent hospital admission, and might be used to improve initial disposition decision and discharge instructions.

Abstract
Full scan mode of liquid chromatography-mass spectrometry equipped with an electrospray ionization source offers a chance on global detection of complicated components; however, the scan mode carries significant challenges in rapidly capturing information of analysts. Sodiation-based in-source collision was proposed here, as a technique for rapid detecting untargeted analytes in full scan analysis, which was based on the stability of sodium adducts and the nonselectivity of in-source collision. Then the technique was applied to profile of angular-type pyranocoumarins (APs) in Radix Peucedani, with full scan analysis performed at two specific in-source collision energy: a high energy 50 V that is tolerated by the sodium adducts of APs, and a low energy 10 V, at which abundant adducts were offered. The spectra list of two average mass spectra was exported, and stable ions were selected based on the intensity ratio of standards at the two collision energy. Then 27 plausible [M + Na]+ m/z values of APs were acquired after filtering the fragment ion and isotope ions and validating with [M + NH4 ]+ . Eighty-two APs finally were tentatively identified based on their accurate spectral data of MSn , fragmentation rules, and elution order regardless of their absolute configuration, which included 25 reported APs from Peucedanum praeruptorum Dunn. The technique provided a novel application of sodium adduct in qualitative analysis. And it was valuable for rapidly capturing information of analytes in full scan analysis, not only for APs but also for other compounds that could form sodium adducts.

Abstract
OBJECTIVE Organophosphate insecticide (OPI) self-poisoning is a major medical problem in many countries. Several studies have demonstrated that the base deficit (BD) is a prognostic tool that is correlated with the severity of injury and predicted mortality, particularly in trauma patients. Here, we aimed to investigate the prognostic significance of BD in OPI poisoning. METHODS This retrospective observational study was conducted between January 1, 2006, and January 31, 2015, at a single emergency department (ED). The BD values were divided into quartiles according to the number of patients: 3 mEq/L or less, 3-5.9 mEq/L, 6-9.9 mEq/L, and 10 mEq/L or greater. Survival at 30 days from ED admission was estimated using the Kaplan-Meier survival analysis. RESULTS Among 154 patients, 31 died, yielding a mortality of 20.1%. The highest BD quartile (≥ 10 mEq/L) and the 6-9.9 mEq/L group were associated with an increased risk of 30-day mortality. Patients with a BD of 10 mEq/L or greater had a 5.85-fold higher risk of 30-day mortality and patients with a BD of 6-9.9 mEq/L had a 5.40-fold higher risk of 30-day mortality compared to patients with a BD of 3 mEq/L or less. The area under the curves of the BD and the Acute Physiology and Chronic Health Evaluation II score for mortality were 0.748 (95% confidence interval (CI), 0.660-0.835) and 0.852 (95% CI, 0.789-0.915), respectively. CONCLUSIONS This study showed that the BD is a predictor of 30-day mortality in patients with OPI poisoning.

Abstract
AIM Skeletal muscle atrophy following prolonged immobilization (IM) is a catabolic state characterized by increased proteolysis and functional deterioration. Previous research indicates that discord of mitochondrial homoeostasis plays a critical role in muscle atrophy. We hypothesized that muscle IM would activate the ubiquitin-proteolysis, autophagy-lysosome (mitophagy) pathway, mitochondrial dynamics remodelling and apoptosis partially controlled by the FoxO signalling pathway. METHODS Female FVB/N mice were randomly divided into five groups (n = 8 each): control (CON), IM with banding of one of the hindlimbs for 1, 2 and 3 weeks (1w-, 2w- and 3w-IM) and 2w-IM followed by 1 week of remobilization (RM). RESULTS Mitochondrial density and DNA copies in tibialis anterior (TA) muscle were reduced by approx. 80% (P < 0.05 for 2w-IM; P < 0.01 for 3w-IM), along with activation of FoxO3a, atrogin-1 and MuRF1 following 2w- and 3w-IM (P < 0.01). Protein markers of autophagy/mitophagy, such as beclin 1 (approx. 2.7-fold; P < 0.01), LC3, ubiquitin-binding adaptor (approx. 1.47-fold; P < 0.01), Rheb (approx. 1.9-fold; P < 0.05) and parkin (approx. 70%; P < 0.05), were all increased by IM and remained activated after RM, whereas BNIP3 and PINK1 levels were decreased by IM (P < 0.05), but elevated upon RM (P < 0.01). IM decreased Mfn2 expression (approx. 50%; P < 0.01) and increased Fis-1 expression (approx. 2.4-fold; P < 0.05). Muscle apoptosis indicator Bax/Bcl2 ratio was elevated at 2w- to 3w-IM (approx. 3.7-fold; P < 0.01), whereas caspase-3 activity was five- to sixfold higher (P < 0.01) and remained threefold higher above CON (P < 0.05). CONCLUSION Our data indicate that IM-induced mitochondrial deterioration is associated with altered protein expressions in the autophagic/mitophagic pathway, more fragmented mitochondrial network and activation of apoptosis partly under the influence of FoxO3 activation.

Abstract
OBJECTIVE Theoretical predicting cytotoxic T lymphocyte (CTL) epitopes are an important tool in vaccine design and CTL therapy for enhancing our understanding of the cellular immune system. We would like to identify available CTL epitopes against HIV-1 Korean clade B. CTL activity was assessed in freshly isolated peripheral blood mononuclear cells from Korean HIV patients in order to assess whether these CTL epitopes induce a cell-mediated immune response (CMI). METHODS NetCTLpan1.1 software, which is the most popular prediction computer software package, and full atom-based simulation (FABS), which is a 3D modelling system for binding activity between epitopes and human leucocyte antigen (HLA) molecules, were used to predict the peptide-spanning Env region binding to HLA-A*24:02, HLA-A*02:01 and HLA-B*15:01, which are frequently found in the Korean population. Granzyme B and interferon-γ ELISPOT assays were used to determine whether identified CTL epitopes induce CMI. RESULTS Three HIV-1 Korean clade B-specific Env CTL epitopes were identified: Gp41-RYL and Gp41-RQG are localized within gp41, and Gp120-LLQ within gp120. In in vitro assays using granzyme B ELISPOT, Gp120-LLQ and Gp41-RQG induced epitope-specific CTL responses in HLA-restricted cells. In ex vivo assay using IFN-γ ELISPOT, cell-mediated immune responses to Gp41-RYL were present in 50% of HLA-matched patients, and responses to Gp120-LLQ and Gp41-RQG were found in 33% of HLA-matched patients. CONCLUSION In this study, we found that a prediction pipeline for CTL epitopes might be based on the most popular computer prediction software and FABS methods. Our results suggest that these CTL epitopes may provide useful tools and information for the development of a therapeutic vaccine against HIV-1 Korean clade B.

Abstract
OBJECTIVE Some studies have evaluated the prognostic indicators associated with acute paraquat (PQ) poisoning. In this study, we externally validated the Yamaguchi index, which showed a good prognostic relevance in predicting the outcome of PQ poisoning. METHODS A retrospective analysis of 297 patients was performed. The Yamaguchi index was calculated using the following equation: Eq1 = (K(+) × HCO3(-))/(Creatinine × 0.088)(mEq/L) against time from PQ ingestion (T). The patients were divided into three groups: group A: Eq1 > 1500 - 399 × log T, group B: 930 - 399 × log T < Eq1 ≤ 1500 - 399 × log T, and group C: Eq1 ≤ 930 - 399 × log T). RESULTS The overall mortality rate was 65.3% (194 of 297). The mortality rates of the three groups stratified by the Yamaguchi index were 7.1% (2 of 28), 22.4% (15 of 67), and 87.6% (177 of 202). The area under the receiver-operating characteristic curve for predicting mortality from the external validation of the Yamaguchi index was 0.842 (95% confidence interval: 0.795-0.882). CONCLUSION The Yamaguchi index is a reliable prognostic factor and could be helpful in predicting mortality due to PQ poisoning.

Abstract
Novel aromatic poly(benzoxazole–imide)s containing naphthalene were prepared from synthesized 1,4-di(5-aminobenzoxazol-2-yl)naphthalene and commercial dianhydrides by conventional two-step polymerization. The polymers showed high levels of tensile strength of up to 294 MPa and modulus of up to 6.5 GPa. The glass transition temperatures of the polymers were observed between 267°C and 345°C. The 5% weight loss temperatures of the polymers were tested in the range of 517–562°C in nitrogen atmosphere. The excellent properties of polymers were attributed to their rigid-rod-like molecular structure. The polymers emitted different fluorescence with maximum emission wavelengths in the range of 470–560 nm. Increasing the dianhydride electron affinity, the emission spectra peak value of polyimides (PIs) except PI6 increased gradually, but the fluorescent intensity of the PIs decreased. The 1,4-bis(3,4-dicarboxyphenoxy)benzene dianhydride-derived PI film exhibit highly fluorescent characteristics; however, the PI film from pyromellitic dianhydride was nonfluorescent.

Abstract
Sepsis is a life-threatening condition, but the pathophysiological basis and biomarkers for the monitoring of sepsis and as targets for therapy remain to be determined. We have shown previously that T cell immunoglobulin and mucin domain protein 3 (Tim-3), a negative immune regulator, is involved in the physiopathology of sepsis, but the underlying mechanisms remain unclear. In the present study, we showed that Tim-3 signalling modulated the response patterns of both macrophages and T helper cells in sepsis. Blockade of the Tim-3 pathway exacerbated sepsis-induced proinflammatory macrophage responses and lymphocyte apoptosis during the early phase of sepsis, and enhanced the shift to anti-inflammatory responses for both macrophages and T helper cells during the late phase of sepsis. Tim-3 signalling was found to regulate CD80 and CD86 expression on macrophages both in vivo and in vitro. Co-culture of T cells with Tim-3 knock-down macrophages led to a biased T helper type 2 (Th2) response, partially explaining how Tim-3 signalling shapes inflammation patterns in vivo. Further studies on this pathway might shed new light on the pathogenesis of sepsis and suggest new approaches for intervention.

Abstract
AIM This study aims to investigate the correlation of carotid arterial sclerosis and left ventricular diastolic function in hyperthyroidism. METHODS A total of 70 patients with newly-diagnosed hyperthyroidism, including 32 patients clinically cured or improved after I131 therapy, were compared with 74 healthy cases in the control group. Bilateral carotid ultrasound and echocardiography were performed in all subjects. The carotid sclerosis index B, compliance coefficient CC, pulse wave velocity (PWV) and left ventricular diastolic function parameters (mitral valve diastolic peak velocity ratio E/A, mitral annulus tissue Doppler diastolic peak velocity ratio e/a and E/e) were obtained. RESULTS The B, CC, PWV and E/e exhibited correlation. Pre-treatment CC was negatively correlated with E/e (r=-0.325, P<0.01), whereas B and PWV were positively correlated with E/e (r=0.270 and 0.297, P < 0.05). Post-treatment CC was negatively correlated with E/e (r=-0.462, P<0.01), whereas B and PWV were positively correlated with E/e (r=0.513 and 0.479, P<0.01). CONCLUSION Carotid artery function and left ventricular diastolic function of hyperthyroid patients were damaged before the treatment and recovered after the treatment. Thus, a correlation existed between them. The early detection of carotid artery function could help the early detection of cardiovascular disease in the hyperthyroid patients.

Abstract
OBJECTIVES Atherosclerosis is an inflammatory disease of the arterial wall that leads to myocardial infarction and stroke. Regulatory T cells (Tregs) and IL-10 exert significant anti-atherogenic effects in experimental models of atherosclerosis by modulating vascular inflammation. We have previously shown that Mycobacterium bovis BCG killed by extended freeze-drying (EFD BCG) decreases lung and colon inflammation by recruiting IL-10-producing Tregs. Therefore, the aim of this study was to investigate the effect of EFD BCG on the development of atherosclerosis. DESIGN We used two strains of atherosclerosis-prone mice: Ldlr(-/-) (four or six EFD BCG injections) and Apoe(-/-) (six injections). RESULTS In both models, EFD BCG significantly reduced the size of atherosclerotic lesions, increased IL-10 production and reduced the serum levels of pro-inflammatory cytokines (IL-6, IL-13, KC and tumour necrosis factor-α). Shortly after treatment with EFD BCG, the number of plasmacytoid dendritic cells (pDCs) and Foxp3(+) Tregs in the draining lymph nodes increased. EFD BCG also led to accumulation of Tregs, but not of pDCs in the spleen, and reduced activity of NF-κB and increased activity of PPAR-γ in both the spleen and vascular tissue of treated mice. CONCLUSION EFD BCG has atheroprotective effects through IL-10 production and Treg expansion. These findings support a novel approach to the prevention and treatment of atherosclerosis.

Abstract
Objective K. K. and S.-K. C. are co-first authors, and C. K. and S.-C. B. are co-senior authors. Two transcription factors in the type I interferon pathway, IRF5 and STAT4, have been genetically associated with susceptibility to both systemic lupus erythematosus (SLE) and rheumatoid arthritis (RA). This study aimed to determine whether these two genes interact with each other to affect the disease susceptibilities. Methods The genetic interactions between IRF5 and STAT4 polymorphisms in SLE and RA susceptibility were examined using the epistasis options in PLINK software. This study analyzes the genetic data from 2558 unrelated Korean participants including 589 SLE patients, 987 RA patients, and 982 controls. Results All 12 polymorphisms were individually associated with SLE susceptibility ( p = 2.49 × 10−8 to 0.00360). Among the three SLE-associated polymorphisms of IRF5, rs77571059, alternatively called CGGGG(3–4) indel, exhibited the lowest p value (4.60 × 10−5) and accounted for the observed associations of the other two single-nucleotide polymorphisms (SNPs). Among the nine SLE-associated SNPs of STAT4, rs16833215 exhibited the lowest p value (2.49 × 10−8) and accounted for all the other associations. These two polymorphisms, rs77571059 of IRF5 and rs16833215 of STAT4, interacted with each other for SLE susceptibility in a redundant manner (ORinteraction = 0.77, Pepistasis = 0.040). Furthermore, these two polymorphisms, which had been individually associated with RA susceptibility, also interacted for RA susceptibility in the same manner (ORinteraction = 0.75, Pepistasis = 0.014). Conclusions A redundant interaction between IRF5 and STAT4 polymorphisms was found in susceptibility to the type I interferon pathway-associated rheumatic autoimmune diseases, SLE and RA, calling for further studies on confirmation of these findings.

Abstract
Cluster of differentiation antigen 14 (CD14) plays a crucial role in the inflammatory response to lipopolysaccharide (LPS), which interacts with TLR4 and MD-2 to enable cell activation, leading to inflammation. Several studies have proved that upstream inhibition of bacterial LPS/toll-like receptor 4 (TLR4)/CD14-mediated inflammation pathway is an effective therapeutic approach for attenuating damaging immune activation. In this study, to explore the effect of CD14 down-regulation on TLR4 signal conductive-related genes expression after stimulation by LPS, five CD14 shRNA (319/421/755/970/1041) sequences and a negative control sequence (NC-1864) were synthesised and used to construct lentiviral recombinant plasmid pSicoR-GFP-shRNA. Lentiviral recombinant plasmids of pSicoR-GFP-shRNA and fusion expression vector of pDsRed-N1-buffalo CD14 were co-transfected into HEK293 using liposome. At 72 h after transfection, the expression of exogenous buffalo CD14 mRNA was reduced at different level for all shRNA plasmids, in which shRNA-1041 had the highest interfering efficiency by RT-qPCR and fluorescence-activated cell sorting analysis. Then, buffalo peripheral blood monocyte/macrophage was purified and infected by the CD14 shRNA lentivirus. After 7 days of infection, the cells were stimulated by 1 µg mL–1 LPS for 3 h, then the mRNA expression level of CD14, TLR4, IL-6, and TNF-α transcripts in the cells were detected by the RT-qPCR method. After stimulation by LPS, the expression of endogenous CD14 was significantly reduced by CD14 shRNA-1041, the mRNA expression level of TLR4, IL-6, and TNF-α genes was also significantly down-regulated in comparison with control group (P ≤ 0.01). In conclusion, the selected CD14 shRNA-1041 cannot only inhibit the expression of endogenous CD14 mRNA in buffalo peripheral blood monocyte/macrophage, but also downregulate the mRNA expression of CD14, TLR4, IL-6, and TNF-α. The above results demonstrate that knockdown of endogenous CD14 has obvious coordination effects on the signal conductive function of TLR4 after stimulating by LPS, and shRNA technology will provide a new way to prevent endotoxin-related diseases in livestock.

Abstract
In order to identify functional residues of the bacteriophage SP6 RNA polymerase, its C-terminal one-twelfth region was randomly mutagenized using polymerase chain reactions of its gene under the conditions for reduced fidelity of Taq DNA polymerase. Using a two-vector system that permits phenotypic isolation of mutants with reduced in vivo transcription activity, 3 single and 1 multiple mutants were isolated. A single substitution of Gln for His805 resulted in complete inactivation of the enzyme. A multiple mutant carrying substitutions at 808, 820, 835, 843 and 848 also abolished the activity. However, changes of Pro856-->Ser and Asp862-->Glu individually reduced the activity only slightly. It is noteworthy that His805 is one of the two motif-C residues that are absolutely conserved among all the DNA polymerases and monomeric RNA polymerases.

Abstract
This study aimed at exploring the correlation between DJ-1 gene and survivin gene in laryngeal squamous cell carcinoma by analyzing their gene expression levels and their relationship with clinicopathologic parameters. The expression of DJ-1 gene and survivin gene in 82 laryngeal carcinoma tissues from patients and 82 negative surgical margin tissue samples were detected by immunohistochemistry, respectively. The correlation of their expression levels and patients' clinical parameters were then analyzed by Pearson correlation analysis. The positive detection rates of DJ-1 and survivin in laryngeal carcinoma tissues were 71.95% and 60.98%, which were higher than those of the normal control that were 29.27% and 0.00%, respectively (P<0.01). The positive detection rates of DJ-1 and survivin were found associated with tumor stages (P<0.05), but not with lymph node metastasis. The DJ-1 gene expression level was related to cell differentiation (P<0.05). Finally, a positive correlation between DJ-1 and survivin gene expression in laryngeal carcinoma was found. The overall survival rate of patients was 51.2%, and disease-free survival (DFS) was 39.0%. DFS in DJ-1 negative-expression group was 87.0%, and 20.3% in DJ-1 positive-expression group. The negative expression of DJ-1 was associated with a shorter mean patient DFS time (44.643±1.417 months), whereas positive expression of DJ-1 was associated with a longer mean DSF time (25.943±;1.297 months). DJ-1 and survivin play a vital role in the occurrence and development of laryngeal carcinoma. DJ-1 may promote the carcinogenesis of laryngeal cells by up-regulating the survivin gene expression.

Abstract
AbstractHigh-resolution electron microscopic examination of alkoxide thin-film gels has been employed to study the drying and aging of thin-film Pb(Zr0.45Ti0.55)O2(OR)2as it evolves from the gel to the ferroelectric perovskite product. The initially amorphous film is observed to aggregate to form ordered islands with inter-metal distances close to that of the final structure embedded in a highly disordered matrix. When these aggregates are at the surface they grow and decompose more rapidly to the perovskite product. The progress to a polycrystalline final state is followed and recorded in real time and in time-lapse at high resolution.
