Abstract
OBJECTIVE This study aimed to explore the characteristics of carbapenem-resistant Enterobacterales (CRE) patients in the intensive care unit (ICU) in different regions of Henan Province to provide evidence for the targeted prevention and treatment of CRE. METHODS This was a cross-sectional study. CRE screening was conducted in the ICUs of 78 hospitals in Henan Province, China, on March 10, 2021. The patients were divided into provincial capital hospitals and nonprovincial capital hospitals for comparative analysis. RESULTS This study involved 1009 patients in total, of whom 241 were CRE-positive patients, 92 were in the provincial capital hospital and 149 were in the nonprovincial capital hospital. Provincial capital hospitals had a higher rate of CRE positivity, and there was a significant difference in the rate of CRE positivity between the two groups. The body temperature; immunosuppressed state; transfer from the ICU to other hospitals; and use of enemas, arterial catheters, carbapenems, or tigecycline at the provincial capital hospital were greater than those at the nonprovincial capital hospital (P < 0.05). However, there was no significant difference in the distribution of carbapenemase strains or enzymes between the two groups. CONCLUSIONS The detection rate of CRE was significantly greater in provincial capital hospitals than in nonprovincial capital hospitals. The source of the patients, invasive procedures, and use of advanced antibiotics may account for the differences. Carbapenem-resistant Klebsiella pneumoniae (CR-KPN) was the most prevalent strain. Klebsiella pneumoniae carbapenemase (KPC) was the predominant carbapenemase enzyme. The distributions of carbapenemase strains and enzymes were similar in different regions.

Abstract
Objective To investigate the expressions of IL-18, IL-18 binding protein isoform a (IL-18BPa) and IL-18 receptor α (IL-18Rα) in blood CD4+ Th2 cells of patients with allergic rhinitis (AR) and the effects of allergens on their expressions. Methods Blood samples of AR patients and healthy control subjects (HCs) were collected. Peripheral blood mononuclear cells (PBMCs) and CD4+ T cells sorted by immunomagnetic beads were stimulated by crude extract of Artemisia sieversiana wild allergen (ASWE), Platanus pollen (PPE) and house dust mite extract (HDME). Flow cytometry was used to detect the expression of IL-18, IL-18BPa and IL-18Rα in CD4+ Th2 cells, and BioPlex was used to detect the level of plasma IL-4 and analyze its correlation with the proportion of IL-18+ Th2 cells. Results Compared with HCs, the proportion of IL-18+ cells was increased in Th2 cells of AR patients; MFI of IL-18 was increased, while that of IL-18Rα was decreased. Moreover, allergens induced IL-18 and IL-18Rα expression in sorted CD4+ Th2 cells of HCs and induced IL-18Rα in that of AR patients. Additionally, elevated plasma IL-4 level was found in AR patients, which was moderately correlated with the percentage of IL-18+ Th2 cells. Conclusion Allergens may be involved in the pathogenesis of AR by inducing expression of IL-18 in peripheral blood CD4+ Th2 cells.

Abstract
PURPOSE/OBJECTIVE(S) Brentuximab vedotin (BV) and immune checkpoint inhibitors (ICIs) had important roles in the treatment of relapse or refractory (R/R) Hodgkin lymphoma (HL). Treatment of refractory disease after BV and -/or ICIs remains a challenge. This study was conducted to evaluate the efficacy and safety of radiotherapy for R/R HL after failure to BV or ICIs. MATERIALS/METHODS We retrospectively analyzed patients in two institutions with R/R HL who had failed after first-line therapy, and were refractory to BV or ICIs, and received radiotherapy (RT) thereafter. The overall response rate (ORR), duration of response (DOR), progression-free survival (PFS) and overall survival (OS) were analyzed. RESULTS A total of 19 patients were enrolled. First-line systemic therapy consisted of ABVD (84.2%), AVD + ICIs (10.5%) and BEACOPP (5.3%), respectively. After first-line therapy, 15 patients (78.9%) were refractory, and 4 patients (21.1%) relapsed. After diagnosis of R/R HL, 8 patients (42.1%) received BV, and 17 patients (89.5%) received ICIs. RT was delivered in all 19 patients who failed after BV or ICIs. In 16 efficacy-evaluable patients, the ORR and CR rate were 100% and 100%. The median DOR was 17.2 months (range, 7.9 to 46.7 months). 3 patients progressed at outside of the radiation field. The in-field-response rate was 100%. The 12-month PFS and OS were 84.4% and 100%, respectively. No patients were reported with sever adverse events. CONCLUSION This study concluded that radiotherapy was effective and safe for refractory HL after BV or ICIs. Further prospective studies were warranted.

Abstract
We report on an evaluation of an optical clock that uses the ^{2}S_{1/2}→^{2}D_{5/2} transition of a single ^{88}Sr^{+} ion as the reference. In contrast to previous work, we estimate the effective temperature of the blackbody radiation that shifts the reference transition directly during operation from the corresponding frequency shift and the well-characterized sensitivity to thermal radiation. We measure the clock output frequency against an independent ^{171}Yb^{+} ion clock, based on the ^{2}S_{1/2}(F=0)→^{2}F_{7/2}(F=3) electric octupole (E3) transition, and determine the frequency ratio with a total fractional uncertainty of 2.3×10^{-17}. Relying on a previous measurement of the ^{171}Yb^{+} (E3) clock frequency, we find the absolute frequency of the ^{88}Sr^{+} clock transition to be 444 779 044 095 485.277(59) Hz. Our result reduces the uncertainty by a factor of 3 compared with the previously most accurate measurement and may help to resolve so far inconsistent determinations of this value. We also show that for three simultaneously interrogated ^{88}Sr^{+} ions, the increased number causes the expected improvement of the short-term frequency instability of the optical clock without degrading its systematic uncertainty.

Abstract
PURPOSE The significance of detecting human herpesvirus 7 (HHV-7) in the lower respiratory tract of patients with severe pneumonia is unclear. This study aims to evaluate the clinical characteristics and prognosis of detecting HHV-7 in the lower respiratory tract of patients with severe pneumonia. METHODS Patients with severe pneumonia requiring invasive mechanical ventilation and underwent commercial metagenomic next-generation sequencing (mNGS) testing of bronchoalveolar lavage fluid from January 2019 to March 2023 were enrolled in 12 medical centers. Clinical data of patients were collected retrospectively, and propensity score matching was used for subgroup analysis and mortality assessment. RESULTS In a total number of 721 patients, 45 cases (6.24%) were identified with HHV-7 positive in lower respiratory tract. HHV-7 positive patients were younger (59.2 vs 64.4, p = 0.032) and had a higher rate of co-detection with Cytomegalovirus (42.2% vs 20.7%, p = 0.001) and Epstein-Barr virus (35.6% vs 18.2%, p = 0.008). After propensity score matching for gender, age, SOFA score at ICU admission, and days from ICU admission to mNGS assay, there was no statistically significant difference in the 28-day mortality rate between HHV-7 positive and negative patients (46.2% vs 36.0%, p = 0.395). Multivariate Cox regression analysis adjusting for gender, age, and SOFA score showed that HHV-7 positive was not an independent risk factor for 28-day mortality (HR 1.783, 95%CI 0.936-3.400, p = 0.079). CONCLUSION HHV-7 was detected in the lungs of 6.24% of patients with severe pneumonia. The presence of HHV-7 in patients with severe pneumonia requiring invasive mechanical ventilation is associated with a younger age and co-detected of Cytomegalovirus and Epstein-Barr virus. While HHV-7 positivity was not found to be an independent risk factor for mortality in this cohort, this result may have been influenced by the relatively small sample size of the study.

Abstract
Carbapenem-resistant Klebsiella pneumoniae (CRKP) has disseminated globally and is difficult to treat, causing increased morbidity and mortality rates in critically ill patients. We conducted a multicenter cross-sectional study of intensive care unit (ICU) inpatients in 78 hospitals to investigate the prevalence and molecular characteristics of CRKP in Henan Province, China, a hyperepidemic region. A total of 327 isolates were collected and downsampled to 189 for whole-genome sequencing. Molecular typing revealed that sequence type 11 (ST11) of clonal group 258 (CG258) was predominant (88.9%, n = 168), followed by ST2237 (5.8%, n = 11) and ST15 (2.6%, n = 5). We used core genome multilocus sequence typing (cgMLST) to further classified the population into 13 subtypes. Capsule polysaccharide (K-antigen) and lipopolysaccharide (LPS; O-antigen) typing revealed that K64 (48.1%, n = 91) and O2a (49.2%, n = 93) were the most common. We studied isolates collected from both the airway and the gut of the same patients and showed that intestinal carriage was associated with respiratory colonization (odds ratio = 10.80, P < 0.0001). Most isolates (95.2%, n = 180) showed multiple drug resistance (MDR), while 59.8% (n = 113) exhibited extensive drug resistance (XDR), and all isolates harbored either blaKPC-2 (98.9%, n = 187) or blaCTX-M and blaSHV extended-spectrum beta-lactamases (ESBLs) (75.7%, n = 143). However, most were susceptible to ceftazidime-avibactam (CZA) (94.7%, n = 179) and colistin (97.9%, n = 185). We found mgrB truncations in isolates conferring resistance to colistin and mutations in blaSHV and OmpK35 and OmpK36 osmoporins in CZA-resistant isolates. Using a regularized regression model, we found that the aerobactin sequence type and the salmochelin sequence type, among others, were predictors of the hypermucoviscosity phenotype. IMPORTANCE In this study, we address the ongoing epidemic of carbapenem-resistant Klebsiella pneumoniae, a critical threat to public health. The alarming genotypic and phenotypic convergence of multidrug resistance and virulence highlights the increasingly aggravated threat posed by K. pneumoniae. This calls for a combined effort of physicians and scientists to study the potential mechanisms and establish guidelines for antimicrobial therapies and interventions. To this end, we have conducted a genomic epidemiology and characterization study using isolates collected in a coordinated effort of multiple hospitals. Innovative biological discoveries of clinical importance are made and brought to the attention of clinical researchers and practitioners. This study presents an important advance in the application of genomics and statistics to recognize, understand, and control an infectious disease of concern.

Abstract
BACKGROUND The appropriate administration regimen of polymyxin B is yet controversial. The present study aimed to explore the optimal dose of polymyxin B under therapeutic drug monitoring (TDM) guidance. METHODS In China's Henan province, 26 hospitals participated in a randomized controlled trial. We included patients with sepsis caused by carbapenem-resistant Gram-negative bacteria (CR-GNB) susceptible to polymyxin B. The patients were randomly divided into a high-dose (HD) group or a low-dose (LD) group and received 150 mg loading dose, 75 mg every 12 h and 100 mg loading dose, 50 mg every 12 h, respectively. TDM was employed to determine if the dose of polymyxin B needs adjustment based on the area under the concentration-time curve across 24 h at a steady state (ssAUC0-24) of 50-100 mg h/L. The primary outcome was the 14-day clinical response, and the secondary outcomes included 28- and 14-day mortality. RESULTS This trial included 311 patients, with 152 assigned to the HD group and 159 assigned to the LD group. Intention-to-treat analysis showed that the 14-day clinical response was non-significant (p = 0.527): 95/152 (62.5%) in the HD group and 95/159 (59.7%) in the LD group. Kaplan-Meier's 180-day survival curve showed survival advantage in the HD group than in the LD group (p = 0.037). More patients achieved the target ssAUC0-24 in the HD than in the LD group (63.8% vs. 38.9%; p = 0.005) and in the septic shock subgroup compared to all subjects (HD group: 71.4% vs. 63.8%, p = 0.037; LD group: 58.3% vs. 38.9%, p = 0.0005). Also, the target AUC compliance was not correlated with clinical outcomes but with acute kidney injury (AKI) (p = 0.019). Adverse events did not differ between the HD and LD groups. CONCLUSION A fixed polymyxin B loading dose of 150 mg and a maintenance dose of 75 mg every 12 h was safe for patients with sepsis caused by CR-GNB and improves long-term survival. The increased AUC was associated with increased incidence of AKI, and TDM results were valued to prevent AKI.

Abstract
Background Polymyxins have become an important treatment option for carbapenem-resistant organisms (CRO) infections. However, there is a rare of clinical studies on colistin sulfate. This study sought to investigate the rate of clinical improvement and adverse reactions of colistin sulfate in the treatment of severe infections caused by CRO in critically ill patients and assess the factors associated with 28-day all-cause mortality. Methods This multicenter retrospective cohort study included intensive care unit (ICU) patients who received colistin sulfate due to CRO infections during July 2021 and May 2022. The primary endpoint was clinical improvement at end of therapy. Secondary endpoints included adverse reactions bacterial clearance rate and 28-day all-cause mortality. Results A total of 122 patients, who were included between July 2021 and May 2022, were included in this study, of whom 86 (70.5%) showed clinical improvement and 36 (29.5%) showed clinical failure. The comparison of the clinical data of the patients showed that the median sequential organ failure assessment (SOFA) score was higher in the failure group than the improvement group {9.5 [7, 11] vs. 7 [4, 9], P=0.002}, the proportion of patients receiving extracorporeal membrane oxygenation (ECMO) was higher in the failure group than the improvement group (27.8% vs. 12.8%, P=0.046), and the median duration of treatment was longer in the improvement group than the failure group {12 [8, 15] vs. 5.5 [4, 9.75], P<0.001}. A total of 5 (4.1%) patients suffered from acute kidney injury due to increases in creatinine during colistin sulfate treatment. The Cox regression survival analysis showed that the SOFA score [hazards ratio (HR) =1.198, P=0.001], ECMO treatment (HR =2.373, P=0.029), and duration of treatment (HR =0.736, P<0.001) were independently associated with 28-day all-cause mortality. Conclusions Colistin sulfate is a reasonable choice for the treatment of CRO infections in the current treatment options are limited. The possible kidney injury caused by the colistin sulfate requires intensive monitoring.

Abstract
BACKGROUND Intra-abdominal infections are the second most common cause of sepsis in the intensive care unit. Intestinal epithelial injury due to abdominal sepsis results in a variety of pathological changes, such as intestinal bacteria and toxins entering the blood, leading to persistent systemic inflammation and multiple organ dysfunction. The increased apoptosis of intestinal epithelial cells induced by sepsis further exacerbates the progression of sepsis. Although several studies have revealed that circRNAs are involved in intestinal epithelial injury in sepsis, few studies have identified the roles of circRNAs in intestinal epithelial apoptosis. METHODS We used laser capture microdissection to obtain purified epithelial cells located in intestinal crypts from four patients with abdominal sepsis induced by intestinal perforation and four samples from age and sex-matched non-septic patients. Microarray analysis of circRNAs was conducted to assess differentially expressed circRNAs between patients with and without sepsis. Lastly, in vitro and in vivo assays were performed to study the mechanism of circFLNA in intestinal epithelial apoptosis during sepsis. RESULTS circFLNA was upregulated in the intestinal epithelium after abdominal sepsis induced by intestinal perforation. Inhibition of miR-766-3p impaired si-circFLNA-mediated inhibition of apoptosis and inflammation factor levels in lipopolysaccharide (LPS)-treated HIEC-6 cells. circFLNA aggravated apoptosis and inflammation through the Fas-mediated apoptosis pathway in both LPS-treated HIEC-6 cells and a mouse cecal ligation and puncture model. CONCLUSION Our findings showed that circFLNA promotes intestinal injury in abdominal sepsis through the Fas-mediated apoptosis pathway by sponging miR-766-3p. The circFLNA/miR-766-3p/Fas axis has potential as a novel therapeutic target for treating intestinal injury in sepsis.

Abstract
OBJECTIVE To investigate the effects of continuous renal replacement therapy (CRRT) on plasma concentration, clinical efficacy and safety of colistin sulfate. METHODS Clinical data of patients received with colistin sulfate were retrospectively analyzed from our group's previous clinical registration study, which was a prospective, multicenter observation study on the efficacy and pharmacokinetic characteristics of colistin sulfate in patients with severe infection in intensive care unit (ICU). According to whether patients received blood purification treatment, they were divided into CRRT group and non-CRRT group. Baseline data (gender, age, whether complicated with diabetes, chronic nervous system disease, etc), general data (infection of pathogens and sites, steady-state trough concentration, steady-state peak concentration, clinical efficacy, 28-day all-cause mortality, etc) and adverse event (renal injury, nervous system, skin pigmentation, etc) were collected from the two groups. RESULTS A total of 90 patients were enrolled, including 22 patients in the CRRT group and 68 patients in the non-CRRT group. (1) There was no significant difference in gender, age, basic diseases, liver function, infection of pathogens and sites, colistin sulfate dose between the two groups. Compared with the non-CRRT group, the acute physiology and chronic health evaluation II (APACHE II) and sequential organ failure assessment (SOFA) were higher in the CRRT group [APACHE II: 21.77±8.26 vs. 18.01±6.34, P < 0.05; SOFA: 8.5 (7.8, 11.0) vs. 6.0 (4.0, 9.0), P < 0.01], serum creatinine level was higher [μmol/L: 162.0 (119.5, 210.5) vs. 72.0 (52.0, 117.0), P < 0.01]. (2) Plasma concentration: there was no significant difference in steady-state trough concentration between CRRT group and non-CRRT group (mg/L: 0.58±0.30 vs. 0.64±0.25, P = 0.328), nor was there significant difference in steady-state peak concentration (mg/L: 1.02±0.37 vs. 1.18±0.45, P = 0.133). (3) Clinical efficacy: there was no significant difference in clinical response rate between CRRT group and non-CRRT group [68.2% (15/22) vs. 80.9% (55/68), P = 0.213]. (4) Safety: acute kidney injury occurred in 2 patients (2.9%) in the non-CRRT group. No obvious neurological symptoms and skin pigmentation were found in the two groups. CONCLUSIONS CRRT had little effect on the elimination of colistin sulfate. Routine blood concentration monitoring (TDM) is warranted in patients received with CRRT.

Abstract
ObjectiveIn intensive care units (ICUs), carbapenem-resistant Enterobacterales (CRE) pose a significant threat. We aimed to examine the distribution, epidemiological characteristics, and risk factors for CRE positivity in ICUs.Materials and methodsThis cross-sectional study was conducted in 96 ICUs of 78 hospitals in Henan Province, China. The clinical and microbiological data were collected. A multivariable logistic regression model was used to analyze the risk factors for CRE positivity.ResultsA total of 1,009 patients were enrolled. There was a significant difference in CRE positive rate between pharyngeal and anal swabs (15.16 vs. 19.13%, P < 0.001). A total of 297 carbapenem-resistant Klebsiella pneumoniae (CR-KPN), 22 carbapenem-resistant Escherichia coli (CR-ECO), 6 carbapenem-resistant Enterobacter cloacae (CR-ECL), 19 CR-KPN/CR-ECO, and 2 CR-KPN/CR-ECL were detected. Klebsiella pneumoniae carbapenemase (KPC), New Delhi metallo-beta-lactamase (NDM), and a combination of KPC and NDM were detected in 150, 9, and 11 swab samples, respectively. Multivariable logistic regression analysis determined length of ICU stay, chronic neurological disease, transfer from other hospitals, previous infection, and history of antibiotics exposure as independent risk factors for CRE positivity. Age and cardiovascular diseases were independent risk factors for mixed infections of CRE. The occurrence of CRE in secondary and tertiary hospitals was 15.06 and 25.62%, respectively (P < 0.05). Patients from tertiary hospitals had different clinical features compared with those from secondary hospitals, including longer hospital stays, a higher rate of patients transferred from other hospitals, receiving renal replacement therapy, exposure to immunosuppressive drugs, use of antibiotics, and a higher rate of the previous infection.ConclusionIn ICUs in Henan Province, CRE positive rate was very high, mostly KPC-type CR-KPN. Patients with prolonged ICU stay, chronic neurological disease, transfer from other hospitals, previous infection, and history of antibiotic exposure are prone to CRE. Age and cardiovascular diseases are susceptibility factors for mixed infections of CRE. The CRE positive rate in tertiary hospitals was higher than that in secondary hospitals, which may be related to the source of patients, antibiotic exposure, disease severity, and previous infection.

Abstract
This study intends to investigate the effects of miR-142-5p encapsulated by serum-derived extracellular vesicles (EVs) on septic acute lung injury (ALI) following remote ischemic preconditioning (RIPC) through a PTEN-involved mechanism. ALI was induced in rats by lipopolysaccharide (LPS) injection, 24 h before which RIPC was performed via the left lower limb. Next, the binding affinity between miR-142-5p and PTEN was identified. EVs were isolated from serum and injected into rats. The morphology of lung tissues, pulmonary edema, and inflammatory cell infiltration into lung tissues were then assessed, and TNF-α and IL-6 levels in serum and lung tissues were measured. The results indicated that RIPC could attenuate ALI in sepsis. miR-142-5p expression was increased in serum, lung tissues, and serum-derived EVs of ALI rats following RIPC. miR-142-5p could target PTEN to activate the PI3K/Akt signaling pathway. miR-142-5p shuttled by serum-derived EVs reduced pulmonary edema, neutrophil infiltration, and TNF-α and IL-6 levels, thus alleviating ALI in LPS-induced septic rats upon RIPC. Collectively, serum-derived EVs-loaded miR-142-5p downregulated PTEN and activated PI3K/Akt to inhibit ALI in sepsis following RIPC, thus highlighting potential therapeutic molecular targets against ALI in sepsis.

Abstract
Background Polymyxins antibiotics have become the first-line clinical drugs in the treatment of refractory gram-negative bacterial infections. Currently, there is a lack of clinical studies on the effect of extracorporeal membrane oxygenation (ECMO) combined with continuous renal replacement therapy (CRRT) on polymyxin concentrations. The purpose of this report was to investigate the changes in the plasma concentrations of Colistin sulfate during ECMO and CRRT and to provide drug administration programs for critically ill patients receiving ECMO and CRRT. Case Description In this case report, a patient with septic shock caused by severe acute pancreatitis, with abdominal pain and dyspnea as the main manifestations, was treated with ECMO combined with CRRT for life support and multiple anti-infective drugs. However, the symptoms of infection had not got improved, the inflammatory indicators remain high and the body temperature fluctuates repeatedly 36.7–38.5 ℃, was considered as carbapenem-resistant organisms (CROs) infection, and was empirically given Colistin sulfate for anti-infection treatment. Finally, the patient’s condition improved and ECMO and CRRT were gradually withdrawn. At the same time, the plasma concentrations of Colistin sulfate before and after ECMO combined with CRRT, was monitored to determine the changes in the plasma concentrations of Colistin sulfate during ECMO and CRRT. Trough and peak concentrations on the 4th day of venovenous ECMO (VV-ECMO) combined with CRRT were 0.36 and 0.98 mg/L, respectively. After withdrawal of ECMO and CRRT, the concentrations were, respectively, 0.27 and 0.34 mg/L for trough concentrations, and 0.82 and 0.98 mg/L for peak concentrations. The data showed that there were no significant differences in the trough and peak concentrations of Colistin sulfate before and after ECMO and CRRT. No adverse effects occurred during follow-up. Conclusions There were no significant differences in the trough and peak concentrations of Colistin sulfate before and after ECMO and CRRT. Therefore, no dose modification is required for Colistin sulfate in patients receiving ECMO with CRRT.

Abstract
Background Geoeconomic variations in epidemiology, the practice of ventilation, and outcome in invasively ventilated intensive care unit (ICU) patients without acute respiratory distress syndrome (ARDS) remain unexplored. In this analysis we aim to address these gaps using individual patient data of four large observational studies. Methods In this pooled analysis we harmonised individual patient data from the ERICC, LUNG SAFE, PRoVENT, and PRoVENT-iMiC prospective observational studies, which were conducted from June, 2011, to December, 2018, in 534 ICUs in 54 countries. We used the 2016 World Bank classification to define two geoeconomic regions: middle-income countries (MICs) and high-income countries (HICs). ARDS was defined according to the Berlin criteria. Descriptive statistics were used to compare patients in MICs versus HICs. The primary outcome was the use of low tidal volume ventilation (LTVV) for the first 3 days of mechanical ventilation. Secondary outcomes were key ventilation parameters (tidal volume size, positive end-expiratory pressure, fraction of inspired oxygen, peak pressure, plateau pressure, driving pressure, and respiratory rate), patient characteristics, the risk for and actual development of acute respiratory distress syndrome after the first day of ventilation, duration of ventilation, ICU length of stay, and ICU mortality. Findings Of the 7608 patients included in the original studies, this analysis included 3852 patients without ARDS, of whom 2345 were from MICs and 1507 were from HICs. Patients in MICs were younger, shorter and with a slightly lower body-mass index, more often had diabetes and active cancer, but less often chronic obstructive pulmonary disease and heart failure than patients from HICs. Sequential organ failure assessment scores were similar in MICs and HICs. Use of LTVV in MICs and HICs was comparable (42·4% vs 44·2%; absolute difference –1·69 [–9·58 to 6·11] p=0·67; data available in 3174 [82%] of 3852 patients). The median applied positive end expiratory pressure was lower in MICs than in HICs (5 [IQR 5–8] vs 6 [5–8] cm H2O; p=0·0011). ICU mortality was higher in MICs than in HICs (30·5% vs 19·9%; p=0·0004; adjusted effect 16·41% [95% CI 9·52–23·52]; p<0·0001) and was inversely associated with gross domestic product (adjusted odds ratio for a US$10 000 increase per capita 0·80 [95% CI 0·75–0·86]; p<0·0001). Interpretation Despite similar disease severity and ventilation management, ICU mortality in patients without ARDS is higher in MICs than in HICs, with a strong association with country-level economic status. Funding No funding.

Abstract
Objective: To investigate the effect of asiaticoside for fibrosis in lung tissues of rats exposed to silica and to explore its possible mechanism. Methods: 144 SD male rats were randomly divided into control group, model group, positive drug control group, asiaticoside high-dose group, medium-dose group and low-dose group, each group included 24 rats. Rats in the control group were perfused with 1.0 ml of normal saline, and the other groups were given 1.0 ml 50 mg/ml SiO(2) suspension. Gavage of herbal was given from the next day after model establishment, once a day. Rats in the positive drug control group were administration with 30 mg/kg tetrandrine and rats in the low-dose group, medium-dose group and high-dose group were given 20 mg/kg, 40 mg/kg and 60 mg/kg asiaticoside for fibrosis respectively. Rats in the control group and the model group were given 0.9% normal saline. The rats were sacrificed in on the 14th, 28th and 56th day after intragastric administration and collect the lung tissues to detect the content of hydroxyproline, TGF-β(1) and IL-18, observe the pathological changes of the lung tissues by HE and Masson staining and determine the expressions of Col-I, a-SMA, TGF-β in lung tissues by Western Blot. Results: On the 14th day, 28th day and 56th day after model establishment, the lung tissues of rats in the model group showed obvious inflammatory response and accumulation of collagen fibers, and the degree of inflammation and fibrosis increased with time. The intervention of asiaticoside could effectively inhibit the pathological changes of lung tissues. The contents of hydroxyproline, IL-18 and TGF-β1 in lung tissues of model group were higher than those in the control group (P<0.05) , while the level of hydroxyproline, IL-18 and TGF-β1 in asiaticoside groups were significantly decreased, and the difference was statistically signicant (P<0.05) . Compared with the control group, the expression levels of Col-I, TGF-β1and α-SMA in lung tissue of model group were increased (P<0.05) , while the expression level of Col-I, TGF-β1 and α-SMA were decreased after the intervention of asiaticoside, and the difference was statistically signicant (P<0.05) . Conclusion: Asiaticoside can inhibit the increase of Col-I, TGF-β1 and α-SMA content in the SiO(2)-induced lung tissues of rats, reduce the release of TGF-β1 and IL-18 inflammatory factors in lung tissue, and then inhibit the synthesis and deposition of extracellular matrix in rat lung tissue, and improve silicosis fibrosis.

Abstract
The study aimed to investigate the expression of cytokeratin and apoptosis-related molecules in the livers of two types of hepatic echinococcosis mice models and to preliminarily explore the relationship between the expression of cytokeratin and apoptosis in echinococcosis related liver injury. We established a mouse model infected by Echinococcus granulosus and Echinococcus multilocularis and observed the expression of cytokeratin and apoptosis related proteins in the two types of hepatic echinococcosis tissues during different stages by immunohistochemical staining. A co-culture model was established using normal hepatocytes and different concentrations of E. granulosus and E. multilocularis protoscoleces. Cell Counting Kit-8 was used to detect cell proliferation, flow cytometry was used to detect hepatocyte apoptosis, and western blot was used to quantify cytokeratin and apoptosis-related proteins, such as caspase3, caspase9, Bcl-2, and Bax. Surgical specimens were obtained from patients with hepatic echinococcosis to analyze the expressions of cytokeratin, caspase3, caspase9, Bcl-2, and Bax by western blot. The expressions of cytokeratin and caspase3 were analyzed by immunohistochemistry. The qRT-PCR method was used to determine the expression of CK8 and CK18 in the liver tissues. In vivo experiments showed that compared to that in the control group, the cytokeratin and caspase3 proteins in the liver tissues of the two types of hepatic echinococcosis were strongly expressed around the lesions of liver echinococcosis; there was a difference between cytokeratin expression of the two different echinococcosis parasites in the liver. Echinococcus granulosus and Echinococcus multilocularis in the co-culture model in vitro could promote the expression of CK, caspase3, caspase9, and Bax protein, decrease the expression of Bcl-2, promote hepatocyte apoptosis, and inhibit cell proliferation; in clinical samples, we found that compared with that in the normal tissues, the expression of cytokeratin, caspase3, caspase9, and Bax in echinococcus tissues was high, but that in Bcl-2 was low. Furthermore, the expression of CK8 and CK18 mRNA were higher in echinococcus tissues than that in the normal tissues and immunohistochemistry analysis also showed that cytokeratin and caspase3 levels were higher in echinococcus tissues than that in the normal tissues. The expression of cytokeratin and apoptosis-related molecules, reflecting liver damage, is high in the liver and is caused due to hepatic echinococcosis. This study provides the first evidence of cytokeratin could be useful for evaluating liver tissue damage caused by echinococcus infection.

Abstract
Background The aim of this study was to assess whether satellite blood culture (SBC) can improve turnaround times, antibiotic switching, and patient prognosis, relative to laboratory blood culture (LBC). . Methods Patients with sepsis treated in the intensive care units (ICUs) of Henan Provincial People's Hospital from February 5, 2018 to January 19, 2019 who met the inclusion criteria were recruited to the study and divided into the SBC group and LBC group according to different blood culture methods. Patient demographics, blood culture, antibiotic adjustment, and prognosis data were collected and compared between the two groups. . Results A total of 204 blood culture sets from 52 ICU patients, including 100 from the medical microbiology LBC group and 104 from the SBC group, were analyzed in this study. There was no significant difference in the positive rates between the two groups. Time from specimen collection to incubation was significantly shorter in the SBC group than that in the LBC group (1.65 h vs. 3.51 h, z=-4.09, P<0.001). The median time from specimen collection to notification of blood culture positivity was 24.83 h in the SBC group and 27.83 h in the LBC group. Median times from adjustment of antibiotics according to the first report were 26.05 h and 51.71 h in the SBC and LBC groups, respectively, while those according to the final report were 97.17 h and 111.45 h, respectively. Median ICU lengths of stay were 15.00 days and 17.00 days in the SBC and LBC groups, respectively, and median ICU lengths of stay were 18.00 days and 23.50 days, respectively. Mean hospitalization costs were 157.99 and 186.73 thousand yuan in the SBC and LBC groups, respectively. . Conclusion SBC can significantly reduce blood culture turnaround times; however, there were no significant differences between the two blood culture methods in initial reporting of positive cultures, time to adjustment of antibiotic therapy, or medical costs, despite a trend toward improvement.

Abstract
Objective: Septic shock is the severe complication of sepsis, with a high mortality. The inflammatory response regulates the immune status and mediates the progression of septic shock. In this study, we aim to identify the key immune-related genes (IRGs) of septic shock and explore their potential mechanism. Methods: Gene expression profiles of septic shock blood samples and normal whole blood samples were retrieved from the Gene Expression Omnibus (GEO) and Genotype-Tissue Expression Portal (GTEx). The differential expression genes (DEGs) and septic shock-specific immune-related genes (SSSIRGs) were evaluated and identified, along with the immune components by "cell type identification by estimating relative subsets of RNA transcripts (CIBERSORT, version x)" algorithm. Additionally, in order to explore the key regulatory network, the relationship among SSSIRGs, upstream transcription factors (TFs), and downstream signaling pathways were also identified by Gene Set Variation Analysis (GSVA) and co-expression analysis. Moreover, the Connectivity Map (CMap) analysis was applied to find bioactive small molecules against the members of regulation network while Chromatin Immunoprecipitation sequencing (ChIP-seq) and Assay for Targeting Accessible-Chromatin with high-throughput sequencing (ATAC-seq) data were used to validate the regulation mechanism of the network. Results: A total of 14,843 DEGs were found between 63 septic shock blood samples and 337 normal whole blood samples. Then, we identified septic shock-specific 839 IRGs as the intersection of DEGs and IRGs. Moreover, we uncovered the regulatory networks based on co-expression analysis and found 28 co-expression interaction pairs. In the regulation network, protein phosphatase 3, catalytic subunit, alpha isozyme (PPP3CA) may regulate late estrogen response, glycolysis and TNFα signaling via NFκB and HLA; Kirsten rat sarcoma viral oncogene homolog (KRAS) may be related to late estrogen response and HLA; and Toll-like receptor 8 (TLR8) may be associated with TNFα signaling via NFκB. And the regulation mechanisms between TFs and IRGs (TLR8, PPP3CA, and KRAS) were validated by ChIP-seq and ATAC-seq. Conclusion: Our data identify three SSSIRGs (TLR8, PPP3CA, and KRAS) as candidate therapeutic targets for septic shock and provide constructed regulatory networks in septic shock to explore its potential mechanism.

Abstract
Objective: To investigate the interventional effect of metformin on pulmonary inflammation and pulmonary fibrosis in silicotic rats. Methods: In April 2019, 48 Wistar male rats of SPF grade were randomly divided into negative control group, metformin control group, silicon dioxide (SiO2) model group, low, medium and high dose metformin intervention group according to the random number table method, 8 rats in each group. The SiO2 model group and the low, medium and high dose metformin intervention groups were given 1 ml 50 mg/ml of SiO2 by intratracheal instillation, the negative control group and the metformin control group were given 1 ml normal saline by intratracheal instillation. 24 hours later, the low, medium and high dose metformin intervention groups and the metformin control group were treated with 100, 200, 400 and 400 mg/kg metformin daily, the control and SiO2 model groups received normal saline daily. Then the rats were sacrificed at the 28th day after SiO2 exposure. The changes of rat body weight and pathological examination of rat lung tissue were observed, and the lung organ coefficient, the content of hydroxyproline (HYP) , the expression levels of inflammatory factors transforming growth factor beta1 (TGF-β1) , tumor necrosis factor-alpha (TNF-α) , interleukin-1beta (IL-1β) and the protein expression of E-cadherin (E-Cad) , Vimentin, α-SMA were detected. Results: Compared with the negative control group, SiO2 model group had a significant decrease in the body weight of rats (P<0.05) , lung organ coefficient, alveolitis and fibrosis scores, HYP content and the levels of TGF-β1, TNF-α, IL-1β were all significantly increased (P<0.05) . Compared with the SiO2 model group, the weights of the rats in the medium and high dose intervention group of metformin increased significantly (P<0.05) . And after intervention with different doses of metformin, the lung organ coefficient, alveolitis and fibrosis scores, HYP content and the levels of TGF-β1, TNF-α and IL-1β were significantly decreased (P<0.05) . Immunohistochemistry and Western blotting results showed that compared with the negative control group, the expression of E-Cad of the SiO2 model group was decreased, and the expression levels of Vimentin and α-SMA were significantly increased (P<0.05) . After metformin intervention, the expression of E-Cad was significantly increased, the expression levels of Vimentin and α-SMA were significantly decreased (P<0.05) . Conclusion: Metformin can reduce lung tissue inflammation and fibrosis in rats exposed to SiO2 dust, which may be related to reducing the expression of inflammatory factors in lung tissue and inhibiting the EMT process.

Abstract
OBJECTIVE To explore the risk factors of intensive care unit acquired weakness (ICUAW) in patients with sepsis, and to evaluate the predictive value of each risk factor for ICUAW. METHODS A case control study was conducted, 60 septic patients admitted to the intensive care unit (ICU) of Henan Provincial People's Hospital from October 20, 2020 to February 20, 2021 were enrolled. The patients were divided into two groups: sepsis ICUAW group and sepsis non-ICUAW group. The data of gender, age, body mass index (BMI), acute physiology and chronic health evaluation II (APACHE II) score, complications, mechanical ventilation, duration of ICUAW, length of stay in ICU, fasting blood glucose, blood lactic acid (Lac), procalcitonin (PCT), C-reactive protein (CRP), sequential organ failure assessment (SOFA) score, outcome, antimicrobial agent, glucocorticoid, sedatives and analgesics drugs and vasoactive drugs were collected. Risk factors were screened by univariate Logistic regression analysis, and odds ratio (OR) was adjusted by multivariate binary logistic regression, P < 0.05 was considered as independent risk factors. Finally, the receiver operating characteristic curve (ROC curve) was drawn to analyze the predictive value of independent risk factors. RESULTS The APACHE II score of the sepsis ICUAW group was significantly higher than that of the sepsis non-ICUAW group (23.05±8.17 vs. 15.33±4.89, P < 0.05), the total length of stay in the ICU was significantly longer than that of the sepsis non-ICUAW group (days: 15.1±9.2 vs. 8.5±3.4, P < 0.05), the improvement rate of patients was significantly lower than that of the sepsis non-ICUAW group [45.0% (9/20) vs. 95.0% (38/40), P < 0.05]. After univariate Logistic regression and multicollinearity test analysis, 7 factors including APACHE II score, average SOFA score, blood lactic acid, proportion of mechanical ventilation, sedatives and analgesics drugs, type of antibiotics and type of vasoactive drugs were included in the binary Logistic regression model [OR: 1.21, 2.05, 2.26, 0.21, 1.54, 2.07, 1.38, 95% confidence interval (95%CI): 1.09-1.35, 1.42-2.94, 1.12-4.57, 0.05-0.66, 1.03-2.29, 1.27-3.37, 0.96-2.00, all P < 0.05]. Hosmer-Lemchaw test P = 0.901, and the correct percentage of prediction was 85%, indicating good model fit. Multivariate binary Logistic regression analysis showed that APACHE II score and average SOFA score were independent risk factors for the occurrence of ICUAW in septic patients (APACHE II score: OR = 1.17, 95%CI was 1.004-1.376, P = 0.044; average SOFA score: OR = 1.86, 95%CI was 1.157-2.981, P = 0.01). ROC curve analysis showed that the mean value of APACHE II score, average SOFA score and their combined detection had a certain predictive value for the occurrence of ICUAW in sepsis patients, areas under ROC curve (AUC) were 0.787, 0.881, 0.905, 95%CI was 0.646-0.928, 0.791-0.972, 0.828-0.982, all P < 0.05. When the cut-off value was 19.500, 6.225, 0.375, the sensitivity was 75%, 90%, 90%, and the specificity were 80%, 80%, 85%, respectively. CONCLUSIONS APACHE II score and average SOFA score can be used as independent risk factors for the occurrence of ICUAW in sepsis, and their combined predictive value is better than that of individual index.

Abstract
Objective: To investigate the clinical characteristics, diagnosis, treatment and outcome of adnexal torsion at different gestational weeks during pregnancy. Methods: A retrospective analysis was conducted of the clinical data of 24 pregnancy patients with adnexal torsion, aged 21-38 (30.6±4.4) years old, who were admitted and delivered in Peking University Third Hospital from 2015 to 2019. According to the gestational age, all patients were divided into two groups:<28 weeks group (11cases) and ≥28 weeks group (13 cases), to compare the intergroup differences in clinical characteristics, treatment and outcome, and the differences of clinical data and outcome between two groups were compared. Results: The proportion of patients with twin pregnancy and assisted reproductive technology in the<28 weeks group was significantly higher than that in the ≥28 weeks group (5/11 vs 1/13, 8/11 vs 1/13, P<0.05). No significant differences between the two groups were recorded in terms of the size of the adnexal mass, the cycles of torsion and the duration from onset to operation. Compared with the≥28 weeks group, the adnexal removal rate of the<28 weeks group was lower (3/11 vs 6/13), but the difference was not statistically significant. The proportion of blood flow signals of ultrasound before operation, cases undergoing laparoscopic surgery and cases whose pathological findings were physiological cysts in the<28 weeks group were significantly higher than that in the ≥28 weeks group (8/11 vs 4/13, 8/11 vs 0, 8/11vs 4/13; P<0.05). Concerning the pregnancy outcomes, there was no difference in the mode of delivery, the delivery gestational age and the body weight of newborns between the two groups. Conclusions: The patients with adnexal torsion prior to 28 weeks(<28 weeks)of pregnancy were more likely to be conceived by assisted reproductive technologies, and the etiology was more likely to be ovarian physiological cysts. Both laparoscopy and laparotomy were safe and effective in the treatment of adnexal torsion with good outcome for mother and infant in the study.

Abstract
This study aimed to assess the clinical features of coronavirus disease 2019 (COVID-19) patients with VTE, to help develop preventive measures for venous thromboembolism (VTE in COVID-19) cases. COVID-19 patients admitted to Henan Provincial People’s Hospital were retrospectively analyzed, including 23, 4 and 8 cases with mild to moderate, severe and critical symptoms, respectively. VTE incidence, age at onset, relevant laboratory parameters and prognosis were analyzed. Overall, VTE incidence in the 35 patients was 20.0%, occurring in severe (n = 1) and critical (n = 6) cases. D-dimer showed statistical significance in laboratory examination, representing except a diagnostic index and especial can be a prognostic factor in VTE among COVID-19 patients. Severe and critical COVID-19 cases had significantly reduced platelet counts, with a risk of hemorrhage. During treatment, the risk of both hemorrhage and thrombosis should be considered. VTE occurs in COVID-19 cases, affecting individuals with severe and critical symptoms. Significant D-dimer increase is of great significance in the risk assessment of death in critical cases of COVID-19. Appropriate measures should be taken to prevent VTE during treatment.

Abstract
Objective: To investigate the current situation of occupational hazards in automobile manufacturing enterprises in Shandong Province. Methods: From February to May 2019, the convenience sampling method was adopted to conduct on-site occupational health surveys with 20 automobile manufacturing enterprises in Shandong Province as the survey subjects, to detect the occupational hazard factors in the workplaces and individual exposure levels, and to analyze the occupational health check results of operators. Results: There were 13 small-sized, 4 medium-sized and 3 large-sized enterprises among the 20 automobile manufacturing enterprises. The detection results of benzene and toluene in the workplaces met the occupational exposure limits, and the detection results of welding fumes, manganese and its compounds, and xylene exceed the occupational exposure limits. The maximum short-term exposure concentration (C(STE)) of welding fume in the air of workplaces was 24.23 mg/m(3), and the over-standard rate was 11.0% (16/146) . The maximum time-weighted average concentration (C(TWA)) of welding fume of operators is 10.60 mg/m(3), and the over-standard rate was 11.0% (8/73) . The maximum C(STE) of manganese and its compounds in the air of workplaces was 0.879 mg/m(3), and the of manganese and its compounds of operators was 0.175 mg/m(3), and the over-standard rate was 5.7% (4/70) . The maximum xylene C(STE) in the air of workplaces was 230.00 mg/m(3), and the over-standard rate was 3.9% (2/51) . The maximum xylene C(TWA) of operators was 70.40 mg/m(3), the over-standard rate was 3.6% (1/28) . Among the 4775 workers exposed to occupational hazards, 38 (0.80%) were suspected of electric welder's pneumoconiosis, 27 (0.57%) were suspected of manganese poisoning and 31 (0.65%) were suspected of chronic low-concentration benzene and benzene series poisoning. The detection rates of suspected occupational diseases among workers in small and medium-sized enterprises were relatively high, 2.86% (30/1048) and 4.51% (51/1132) respectively. There was a statistically significant difference in the detection rates of suspected occupational diseases among the operators of different scale automobile manufacturers (P<0.05) . Conclusion: The exposure levels of electric welding fumes, manganese and its compounds in welding jobs and xylene exposure levels in spray painting jobsin Shandong Province's automobile manufacturing enterprises are more serious. The supervision and management of occupational hygiene should be strengthened, the working environment should be improved, and the health of welding and painting workers should be protected.

Abstract
In recent years, atomization inhalation therapy has been more and more commonly used in patients with mechanical ventilation. However, the establishment of artificial airway has changed the environment and mode of aerosol delivery. Currently, Expert consensus on atomization inhalation during mechanical ventilation has been established to guide clinical practice. However, many ventilators do not support the treatment of aerosol inhalation due to the tedious procedures and numerous drugs. At the same time, the therapeutic effect of atomization inhalation is affected by many factors, such as ventilator mode selection, parameter setting, heating and humidification, using of artificial nose and filter, etc., which often results in poor clinical effects or even damage to the ventilator. In order to standardize the clinical application of mechanical ventilation atomization inhalation technology and avoid many possible problems in operation, the committee members of Respiratory Therapy Group of Severe Medicine Branch of Henan Medical Association discussed and concluded this clinical path, so as to provide clinical reference for the actual operation and drug administration of mechanical ventilation atomization.

Abstract
We compare two optical clocks based on the ^{2}S_{1/2}(F=0)→^{2}D_{3/2}(F=2) electric quadrupole (E2) and the ^{2}S_{1/2}(F=0)→^{2}F_{7/2}(F=3) electric octupole (E3) transition of ^{171}Yb^{+} and measure the frequency ratio ν_{E3}/ν_{E2}=0.932829404530965376(32), improving upon previous measurements by an order of magnitude. Using two caesium fountain clocks, we find ν_{E3}=642121496772645.10(8) Hz, the most accurate determination of an optical transition frequency to date. Repeated measurements of both quantities over several years are analyzed for potential violations of local position invariance. We improve by factors of about 20 and 2 the limits for fractional temporal variations of the fine structure constant α to 1.0(1.1)×10^{-18}/yr and of the proton-to-electron mass ratio μ to -8(36)×10^{-18}/yr. Using the annual variation of the Sun's gravitational potential at Earth Φ, we improve limits for a potential coupling of both constants to gravity, (c^{2}/α)(dα/dΦ)=14(11)×10^{-9} and (c^{2}/μ)(dμ/dΦ)=7(45)×10^{-8}.

Abstract
We introduce a scheme to coherently suppress second-rank tensor frequency shifts in atomic clocks, relying on the continuous rotation of an external magnetic field during the free atomic state evolution in a Ramsey sequence. The method retrieves the unperturbed frequency within a single interrogation cycle and is readily applicable to various atomic clock systems. For the frequency shift due to the electric quadrupole interaction, we experimentally demonstrate suppression by more than two orders of magnitude for the ^{2}S_{1/2}→^{2}D_{3/2} transition of a single trapped ^{171}Yb^{+} ion. The scheme provides particular advantages in the case of the ^{171}Yb^{+} ^{2}S_{1/2}→^{2}F_{7/2} electric octupole (E3) transition. For an improved estimate of the residual quadrupole shift for this transition, we measure the excited state electric quadrupole moments Θ(^{2}D_{3/2})=1.95(1)ea_{0}^{2} and Θ(^{2}F_{7/2})=-0.0297(5)ea_{0}^{2} with e the elementary charge and a_{0} the Bohr radius, improving the measurement uncertainties by one order of magnitude.

Abstract
OBJECTIVE To explore the effect of micro-ribonucleic acid (miR)-29c on renal fibrosis in diabetic rats through the adenosine 5'-monophosphate-activated protein kinase (AMPK)/mammalian target of rapamycin (mTOR) signaling pathway, and to investigate its related mechanism by the research on the effect of miR-29c on the expression of fibrosis-related genes. MATERIALS AND METHODS The rat model of diabetic nephropathy (DN) was established, and the levels of fasting blood glucose (FBG), 24 h urine protein (24h-Pro), blood urea nitrogen (BUN), and serum creatinine (sCr) were monitored. After the rats were executed, kidney tissues were dissected, stained with paraffin and embedded in hematoxylin and eosin (H&E). Then, Western blotting was used to detect the levels of miR-29c, phosphorylated-AMPK (p-AMPK), α-smooth muscle actin (α-SMA), tumor necrosis factor-α (TNF-α), and macrophage migration inhibitory factor (MIF). The human renal tubular epithelial HK-2 cell line was treated with high glucose (HG) to simulate DN cell status in vivo. After that, the expressions of miR-29c and the renal fibrosis marker α-SMA were examined via Western blotting. Finally, the level of α-SMA was measured by Western blotting after HG treatment combined with miR-29c silencing. RESULTS The levels of FBG, BUN, sCr, and 24h-Pro in DN model rats were significantly higher than those in rats of control group. The data manifested that the DN model was successfully established. The expression level of miR-29c in DN model rats was markedly increased and that of the downstream protein p-AMPK also exhibited a significantly increasing trend. In addition, the levels of α-SMA, TNF-α, and MIF were elevated. The expression levels of miR-29c and α-SMA were increased markedly after the human renal tubular epithelial HK-2 cell line was treated with HG, but the expression of α-SMA was reduced after HG treatment combined with miR-29c silencing for 24 h. CONCLUSIONS MiR-29c is probably related to the occurrence and development of DN. Besides, miR-29c silencing may inhibit the DN renal fibrosis through AMPK/mTOR signals, so miR-29c may be an effective target for the treatment of DN renal fibrosis.

Abstract
AIMS Interventions using prebiotic inulin-type fructans (ITFs) are widely prescribed to modulate the gut microbiota composition and activity to promote health. However, the impacts of ITFs on post-antibiotic reconstitution of the gut microbiome remain incompletely understood. The aim of the present study was to investigate the effects of ITFs supplementation on intestinal inflammation, the composition of the intestinal microbiota and the colonic transcriptome after antibiotic treatment. METHODS AND RESULTS Male BALB/c mice were subjected to an antibiotic cocktail (ABx) treatment for 7 days, and their microbiomes were then reconstituted either spontaneously or with ITFs supplementation (5%) for 14 days. Our data showed that ITFs supplementation delayed the recovery of antibiotic-induced colitis compared with the spontaneous recovery. Neither ITFs supplementation nor spontaneous recovery could restore the microbial community composition at the genus level back to its initial composition. ITFs supplementation increased the relative abundance of some beneficial bacteria and butyrate levels, but resulted in selective blooms of some opportunistic pathogens and elevated the pathways associated with diseases linked to gut microbiota function. Both ITFs supplementation and spontaneous recovery could restore the colonic transcriptome nearly to the initial profile to a certain extent; however, ITFs supplementation delayed the restoration of the immunoglobulin genes compared to spontaneous recovery. CONCLUSION These data showed that post-antibiotic ITFs consumption did not always lead to beneficial effects but might lead to potential adverse effects in the context of dysbiosis. SIGNIFICANCE AND IMPACT OF THE STUDY These findings highlighted that caution is required when supplementing ITFs to restore intestinal homeostasis in the context of dysbiosis resulting from broad-spectrum antibiotics.

Abstract
Objective: To analyze the correlation between the changes of lung function and serum proinflammatory cytokines in workers occupationally exposed to toluene diisocyanate (TDI), and to explore the evaluation index of respiratory toxicity of TDI. Methods: In October 2014, 61 male workers engaged in TDI synthesis process, purification process, packaging process and the above production process in a TDI factory in western China were selected as TDI exposure group; 62 male enterprise managers who were not exposed to TDI and other known allergenic chemicals were selected as control group, which were matched at the age of workers in exposure group. The questionnaire survey obtained information such as gender, length of service, age, occupational history, exposed length of service and so on. The lung function indexes [forced expiratory volume in the first second (FEV1), forced vital capacity (FVC), FEV1/FVC] and serum levels of interleukin (IL)-1 β, IL-6, IL-8, tumor necrosis factor (TNF)-α, macrophage inflammatory factor-1 β, monocyte chemoattractant factor-1 and vascular endothelial growth factor were measured. The urine was collected after the weekend shift, and the concentration of (TDA), the metabolite of TDI, was determined as the index of internal exposure. Spearman rank correlation was used to analyze the correlation between cytokines and lung function indexes, and multivariate linear regression was used to analyze the changes of lung function indexes and cytokines with TDI exposure concentration and time. Results: The median age (P5-P95) of the exposed group and the control group was 36.5 (24.0-51.0) and 38.0 (24.0-50.0) years, respectively. In the exposed group, the median length of service (P5-P95) was 6.94 (0.97-26.33) years, and the median concentration of TDA in urine was 15.56 (2.28-112.16) ng/ml. The three indexes of lung function, FVC, FEV1, FEV1/FVC and the levels of serum IL-8 and TNF-α were significantly lower than those in the control group (P<0.01). With the increase of exposure concentration and exposure time, the level of serum TNF-α, FVC and FEV1 decreased, and showed a good dose-effect and time-effect relationship (all Ptrend values< 0.05). Serum IL-8 and TNF-α were positively correlated with FVC, FEV1 and FEV1/FVC (all P values<0.01). Conclusion: The levels of serum inflammatory factors IL-8 and TNF-α in worker exposed to TDI are related to lung function indexes, which can be used as early evaluation indexes of respiratory toxicity induced by TDI.

Abstract
OBJECTIVE To explore the usability of regional saturation of cerebral oxygenation (rScO2) combined with percentage of α variability (PAV) in predicting brain function prognosis in patients with traumatic brain injury (TBI). METHODS A retrospective analysis was conducted. The clinical data of patients with TBI who were monitored rScO2 and bedside quantitative electroencephalogram (qEEG) admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from August 2018 to July 2019 were collected. The rScO2, PAV, and Glasgow coma scale (GCS) score were recorded within 72 hours after the TBI. The primary prognostic indicator was the 3-month Glasgow outcome score (GOS) score. The differences between the two groups of poor prognosis of brain function (GOS score 1-3) and good prognosis (GOS score 4-5) were compared. Binary multivariate Logistic regression analysis was used to analyze the correlation between rScO2, PAV, GCS score and the prognosis of brain function in patients with TBI. In addition, receiver operating characteristic (ROC) curve was plotted to analyze the predicting value of rScO2 and PAV only or combination for prognosis of brain function. RESULTS A total of 42 patients with TBI were enrolled in the study, with rScO2 ≥ 0.60 (grade I) in 14 patients, 0.50 ≤ rScO2 < 0.60 (grade II) in 16 patients, and rScO2 < 0.50 (grade III) in 12 patients. PAV 3-4 scores (grade I) were detected in 16 patients, 2 scores (grade II) in 17 patients, and 1 score (grade III) in 9 patients. GCS score 9-14 (grade I) were observed in 13 patients, 4-8 (grade II) in 23 patients, and 3 (grade III) in 6 patients; 18 patients had poor prognosis and 24 had good one. The rScO2, PAV and GCS scores of the poor-prognosis group were significantly higher than those in the good-prognosis group [rScO2 with grade III: 55.6% (10/18) vs. 8.3% (2/24), PAV with grade III: 38.9% (7/18) vs. 8.4% (2/24), GCS score with grade III: 27.7% (5/18) vs. 4.1% (1/24)] with significant differences (all P < 0.05). There was no significant difference in other general data including gender, age, total length of hospital stay or acute physiology and chronic health evaluation II (APACHE II) score between the two groups. Binary multivariate Logistic regression analysis showed that rScO2 and PAV were independent risk factors for prognosis of brain in patients with TBI [rScO2: odds ratio (OR) = 4.656, 95% confidence interval (95%CI) was 1.071-20.233, P = 0.040; PAV: OR = 3.525, 95%CI was 1.044-11.906, P = 0.042]. ROC curve analysis showed that both of rScO2 and PAV had predictive value for the prognosis of brain function in patients with TBI (AUC was 0.796 and 0.780, respectively, both P < 0.01), and rScO2 combined with PAV had higher predictive value with the AUC of 0.851 (P < 0.01) than rScO2 or PAV alone, the sensitivity was 94.4% and the specificity was 62.5%. CONCLUSIONS rScO2 and PAV were associated with early brain function prognosis in patients with TBI. The combination of two monitoring indicators can reliably assess the prognosis of brain function in patients with TBI.

Abstract
Objective: To investigate the current status of the occupational hazards of welding fume, manganese, and manganese compounds in the welding environment of a large container manufacturing enterprise, as well as the status of occupational health examination of workers, and to provide a basis for improving the welding environment of this enterprise. Methods: In August 2016, July 2017, and August 2018, convenience sampling was used to perform an on-site occupational hygiene survey of the welding workshop for three consecutive years, and welding fume, manganese and, manganese compounds (counted as manganese dioxide) were measured for their workplace exposure concentrations and exposure levels in workers. A comprehensive analysis was performed for the results of occupational health examination. Results: Welding fume, manganese, and manganese compounds in the welding environment gradually increased from 2016 to 2018 (χ(2)(trend)=5.14 and 5.54, P<0.05). The maximum over-standard rate of concentration-short term exposure limit was 43.3% (13/30) for welding fume and 40.0% (12/30) for manganese and its compounds, and the maximum over-standard rate of time-weighted average concentration was 26.7% (8/30) for welding fume and 23.3% (7/30) for manganese and its compounds. Abnormalities were observed in the occupational health examination of welding workers in 2016-2018, among which respiratory system abnormalities (cough, expectoration, and wheezing), nervous system abnormalities (dizziness, fatigue, sleep disorders, amnesia, hyperhidrosis, and palpitations), and electrocardiogram abnormalities (bundle conduction block) had an incidence rate of above 10.0%, and the incidence rate of abnormalities on posterior-anterior X-ray high-kV chest radiograph was close to 8.9% (30/336) . Conclusion: There is severe exposure to welding fume, manganese, and manganese compounds among workers in this enterprise, which cause great hazards to the health of workers. It is necessary to strengthen occupational health management, take measures to improve the welding environment, and enhance occupational disease prevention.

Abstract
In order to enhance the high-power performance of the ferrite phase shifter (PS), a method of increasing waveguide height is proposed and experimentally demonstrated. Dual-toroid geometry is utilized as a high-power structure. Two configurations of X-band PSs with full-height (FH) and increased-height (IH) waveguides are designed and fabricated while keeping other parameters consistent. Comparative analysis based on simulation and high-power experiments is conducted. The simulation results agree well with experiments. Compared with the FHPS, the IHPS can enhance the peak-power-capacity from 90 kW to 140 kW while maintaining almost the same insertion loss of 0.5 dB with a slight increase in differential phase shift from 360° to 380°.

Abstract
Objective: To investigate the role of microRNA-29b-3p (miRNA-29b-3p) and miRNA-34c-3p in the process of pulmonary fibrosis, we detected the expression levels of miRNA-29b-3p and miRNA-34c-3p in the lung tissue of rats exposed to silica and A549 cells. Methods: SPF male Wistar rats were randomly divided into 1, 7, 14, 21, 28 d control group and silica (SiO(2)) dusting group, with 6 rats in each group. One-time non-exposure method was used to infuse 1ml SiO(2) suspension. The rat SiO(2) dusting group was established in the liquid, and the control rats were intratracheally injected with 1 ml of sterile physiological saline in the same manner. The lung tissues of each group were collected at the corresponding time points after dusting. Three of the rats were taken out for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. A549 cells were cultured at the in vitro cell level and divided into control group, SiO(2) stimulation group and TGF-β(1) stimulation group, and cells were collected at 12, 24 and 48 h after treatment. The expression levels of miRNA-29b-3p and miRNA-34c-3p in rat lung tissue and A549 cells were verified by real-time PCR (qRT-PCR), target gene prediction of miRNA-29b-3p and miRNA-34c-3p and perform GO enrichment analysis and KEGG pathway analysis. Results: The weight growth rate of the control group was significantly higher than that of the SiO(2) dusting group. Compared with the control group, the lung mass and lung coefficient of the SiO(2) dusting group were significantly increased (P<0.05). The inflammatory response of the lungs in the control group was significantly reduced at 21 and 28 days, and the inflammatory cells infiltrated in the lung tissue of the SiO2 group. The rats in the control group had a small amount of collagen at 21 and 28 days. A large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) for 21 days. Compared with the control group, the expression levels of miRNA-29b-3p and miRNA-34c-3p in the SiO(2) dusting group were significantly down-regulated, and there was significant difference compared with the control group (P<0.05). The expression levels of miRNA-29b-3p and miRNA-34c-3p in A549 cells treated with SiO(2) and human recombinant TGF-β1 were significantly lower than those in the control group at 24 h and 48 h, and the difference was statistically significant (P<0.05). Conclusion: Down-regulation of miRNA-29b-3p and miR-34c-3p in rat lung tissue A549 cells may be associated with the development of early silicosis and is expected to be an indicator of early silicosis diagnosis and prognosis.

Abstract
OBJECTIVE To explore the predictive value of heparin-binding protein (HBP) combined with sequential organ failure assessment (SOFA) score in patients with septic shock. METHODS Seventy-eight patients with sepsis admitted to intensive care unit (ICU) of Henan Provincial People's Hospital from December 2016 to May 2017 were enrolled. Thirty healthy persons were enrolled as controls. The patient's gender, age, length of ICU stay, and blood culture results, white blood cell count (WBC), C-reactive protein (CRP), procalcitonin (PCT), blood lactate (Lac), HBP, SOFA score, acute physiology and chronic health evaluation II (APACHE II) score, organ failure and vasoactive agents usage within 24 hours of admission were recorded. The differences in the above indicators between the groups were compared, and the receiver operating characteristic (ROC) curve was drawn to evaluate the predictive value of HBP, SOFA score and their combination in patients with septic shock. RESULTS All patients were enrolled in the final analysis, including 64 with sepsis and 14 with septic shock. Compared with the sepsis group, the proportion of patients with septic shock who were positive for blood culture, organ failure, and vasoactive agents was higher [57.1% (8/14) vs. 7.8% (5/64), 100.0% (14/14) vs. 65.6% (42/64), 100.0% (14/14) vs. 18.8% (12/64), all P < 0.01], SOFA and APACHE II scores were also higher (SOFA: 8.93±4.16 vs. 5.89±2.68, APACHE II: 22.29±4.89 vs. 15.28±5.14, both P < 0.01); however, there was no significant difference in gender, age or length of ICU stay between the two groups. Compared with the healthy control group, HBP, PCT, CRP and Lac levels were significantly increased in the sepsis group and the septic shock group. HBP in the septic shock group was significantly higher than that in the sepsis group (μg/L: 120.33±43.49 vs. 68.95±54.15, P < 0.05), but there was no significant difference in PCT, CRP or Lac between septic shock group and sepsis group [PCT (μg/L): 1.42 (0.47, 46.00) vs. 0.71 (0.19, 4.50), CRP (mg/L): 102.90±78.12 vs. 102.07±72.15, Lac (mmol/L): 1.81 (1.14, 3.65) vs. 1.59 (1.17, 2.24), all P > 0.05]. It was shown by ROC curve analysis that the area under the ROC curve (AUC) of SOFA score for predicting septic shock was 0.715 [95% confidence interval (95%CI) = 0.540-0.890, P = 0.012], and when the optimal cut-off value was 7.5, the sensitivity was 64.3%, the specificity was 76.6%. The AUC of HBP was 0.814 (95%CI = 0.714-0.913, P < 0.001), and when the optimal cut-off value was 89.43 μg/L, the sensitivity was 78.6%, the specificity was 76.6%; when the two were combined, the AUC was 0.829 (95%CI = 0.724-0.935, P < 0.001), the sensitivity was 92.9%, and the specificity was 61.9%. CONCLUSIONS HBP can be used as a biological indicator for predicting septic shock, and the accuracy of predicting septic shock can be improved with the combination of SOFA score.

Abstract
Objective: To screen the changes of microRNA (miRNA) expression profiles in lung tissues of early silicosis rats, and provide a basis for functional analysis of differential microRNA. Methods: SPF Wistar male rats were randomly divided into a negative control group and SiO(2)-exposed groups, with 30 rats in each group. The model of silicosis in rats was established by intratracheal instillation of 1 ml SiO(2) suspension, and the control rats were treated with 1mL in the same way to sterilize normal saline. The lung tissues of two group were collected at the 1, 7, 14, 21, 28 d after SiO(2)-exposed. Three of the rat lung tissues were used for pathological observation, and the other three were used to screen differentially expressed miRNAs in lung tissue by miRNA microarray technology. miRNA chip screening and RT-qPCR were used to verify the expression levels of miRNA-423-5p and miRNA-26a-5p in the two groups. miRNA-423-5p and miRNA-26a-5p are predicted by target genes and analyzed by GO (gene ontology) enrichment analysis and KEGG (kyoto encyclopedia of genes and genomes) pathway analysis. Results: In the control group, the inflammatory response of lung tissue 21 and 28 days was significantly reduced compared with 1, 7 and 14 days, and the inflammatory cells infiltrated in the lung tissue of the SiO(2)-exposed rats. The rats in the control group had a small amount of collagen at 21 and 28 days, but a large amount of collagen fiber deposition began to appear in the lung tissue of rats exposed to SiO(2) after 21 days. Compared with the control group, the expression levels of micro RNA-423-5p was significantly up-regulated and the expression of microRNA-26a-5p was significantly down-regulated in the SiO(2)-exposed rats lung tissues dust at different time points (P<0.05) . Conclusion: The up-regulation of miRNA-423-5p and the down-regulation of miRNA-26a-5p in lung tissues of early silicotic rats may be related to the occurrence and development of early silicosis.

Abstract
Objective: To observe the repairing effect of adipose mesenchymal stem cells (ADSCs) on lung injury induced by silica in rats. Methods: Primary ADSCs-GFP was obtained from rats. ADSCs-GFP was injected into tail vein of silicosis model rats. The expression of green fluorescence in lungs was observed regularly to determine the homing ability of ADSCs. Primary ADSCs of rats were obtained and randomly divided into control group, exposure group, vehicle group and ADSCs group. Silicosis rat model was established by non-exposed tracheal drip method. 24 hours after silica exposure, rats in ADSCs group were injected with ADSCs of 1×10(6)/kg body weight through tail vein, and the pathological changes of lung tissue were observed and evaluated 28 days after intervention. To explore the early intervention mechanism of ADSCs on pulmonary fibrosis in silicosis model rats, apoptosis-related proteins were detected by immunohistochemistry. Results: 28 days after exposure to silica, rats in the exposure group showed obvious pulmonary fibrosis. Compared with exposure group and vehicle group, ADSCs group showed less pulmonary inflammation, less silica nodules and less collagen deposition area. Immunohistochemical results showed that the expression of Caspase-3 and cytochrome C protein decreased and Bcl-2 protein increased after ADSCs transplantation. Conclusion: ADSCs infusion has an obvious intervention effect on postponing early silicosis fibrosis in rats exposed to silica, and its mechanism is related to the regulation of apoptotic process.

Abstract
OBJECTIVE To explore the characteristic of early evaluation of patients with amplitude-integrated electroencephalogram (aEEG) on brain function prognosis after cardiopulmonary cerebral resuscitation (CPCR). METHODS A retrospective analysis of the clinical data of patients with adult CPCR in intensive care unit (ICU) of Henan Provincial People's Hospital from March 2016 to March 2017 was performed. The length of stay, recovery time, acute physiology and chronic health evaluation II (APACHE II) score, aEEG and Glasgow coma scale (GCS) within 72 hours were recorded. The main clinical outcome was the prognosis of brain function (Glasgow-Pittsburgh cerebral performance category, CPC) in patients with CPCR after 3 months. Relationship between aEEG and GCS and their correlation with brain function prognosis was analyzed by Spearman rank correlation analysis. The effects of aEEG and GCS on prognosis of brain function were evaluated by Logistic regression analysis. The predictive ability of aEEG and GCS for brain function prognosis was evaluated by receiver operating characteristic (ROC) curve. RESULTS A total of 31 patients with CPCR were enrolled, with 18 males and 13 females; mean age was (41.84±16.96) years old; recovery time average was (19.42±10.79) minutes; the length of stay was (14.84±10.86) days; APACHE II score 19.29±6.42; aEEG grade I (normal amplitude) in 7 cases, grade II (mild to moderate abnormal amplitude) in 13 cases, grade III (severe abnormal amplitude) in 11 cases; GCS grade I (9-14 scores) in 7 cases, grade II (4-8 scores) in 14 cases, grade III (3 scores) in 10 cases; 19 survivals, 12 deaths; the prognosis of brain function was good (CPC 1-2) in 8 cases, and the prognosis of brain function was poor (CPC 3-5) in 23 cases. There was no significant difference in age, gender, recovery time, length of stay and APACHE II score between two groups with different brain function prognosis, while aEEG grade and GCS grade were significantly different. Cochran-Armitage trend test showed that the higher the grade of aEEG and GCS, the worse the prognosis of CPCR patients (both P-trend < 0.01). With the increase in GCS classification, the classification of aEEG was also increasing (r = 0.620 6, P = 0.000 3). Both aEEG and GCS were positively correlated with the prognosis of brain function (r1 = 0.779 6, P1 < 0.000 1; r2 = 0.702 1, P2 < 0.000 1). Univariate Logistic regression analysis showed that aEEG and GCS had significant effect on early brain function prognosis [aEEG: odds ratio (OR) = 37.234, 95% confidence interval (95%CI) = 3.168-437.652, P = 0.004, GCS: OR = 12.333, 95%CI = 1.992-76.352, P = 0.007]; after adjusting for aEEG and GCS, only aEEG had significant effect on the early prognosis of brain function (OR = 26.932, 95%CI = 1.729-419.471, P = 0.019). The ROC curve analysis showed that in the evaluation of the prognosis of CPCR patients with brain function, the area under ROC curve (AUC) of aEEG was 0.913, when the cut-off value of aEEG was 1.5, the sensitivity was 95.7% and the specificity was 75.0%. The AUC of GCS was 0.851, the best cut-off value was 1.5, the sensitivity was 91.3% and the specificity was 62.5%. CONCLUSIONS aEEG and GCS scores have a good correlation in the evaluation of brain function prognosis in patients with CPCR, the accuracy of aEEG in the early evaluation of the prognosis of patients with CPCR is higher than the GCS score.

Abstract
To investigate the pathophysiology, screening, diagnosis and treatment of the systemic lupus erythematosus (SLE) in pregnancy complicated with pulmonary hypertension. Retrospective analysis was made of one case of SLE in pregnancy complicated with pulmonary hypertension in Peking University Third Hospital. Literature was reviewed to investigate the pathophysiology, screening, diagnosis and treatment of the SLE in pregnancy complicated with pulmonary hypertension. SLE is an autoimmune mediated diffuse connective tissue disease characterized by immunological inflammation. The incidence of SLE combined with pulmonary hypertension was low, but the risk was high with pregnancy, with a high perinatal mortality rate. Pulmonary hypertension is the leading cause of the death in patients with pregnancy complicated with SLE. This patient was diagnosed with SLE six years before and was hospitalized for 29 weeks of menopause, with fatigue five months and chest congestion one month. Ultrasonic cardiogram showed severe pulmonary hypertension, with pulmonary arterial systolic pressure being 96 mmHg. After admission, multidisciplinary consultation was organized to draw up a diagnosis and treatment plan. The patient received the treatment of rest,oxygen,blood gas and pulmonary artery pressure monitoring. Considering perioperative pulmonary hypertension crisis likely to occur, pulmonary artery catheter was placed preoperatively. In general anesthesia, the cesarean was performedfter operation,the patient was transferred to the intensive care unit, with the treatment of expanding blood vessels, reducing pulmonary artery pressure,administering anticoagulation and preventing infection. Ten days after operation, the patient was discharged from hospital with smooth condition. Strengthening the management of SLE patients in pregnancy, early detection, and cooperation of multidisciplinary teams can help improve maternal and fetal outcomes. Termination of pregnancy should be offered to the patients with severe pulmonary hypertension. Right cardiac catheterization is the gold standard for diagnosing pulmonary hypertension. Some patients are diagnosed in later stage of pregnancy, regular antenatal examination, interdisciplinary co-operation, assessment of cardiac function, monitoring the condition of the pregnant woman and fetus and timely termination of pregnancy are needed. Epidural anesthesia is the appropriate choice for cesarean delivery.

Abstract
OBJECTIVE In recent years, more and more attention has been paid to the occurrence and harm of delirium, and intensive care unit (ICU) delirium has become a hot issue. The incidence of delirium in ICU patients is much higher than that of general wards, all kinds of complications caused by delirium and increased mortality should win enough attention of the clinicians. There is no uniform standard for the diagnosis and evaluation of ICU delirium, which is a major problem that affects clinicians in the early diagnosis and assessment of prognosis. By reviewing the domestic and international researches of ICU delirium, the latest progress of diagnostic and assessment instruments for delirium in ICU is stated, which provides an important basis for the early identification and diagnosis of delirium in ICU.
