Abstract
Our study aims to investigate the impact of probiotic consumption during pregnancy on gut microbiota functional diversity in healthy pregnant women. Thirty-two pregnant women were randomly assigned to two groups. The probiotic group (PG) consisted of pregnant women who consumed triple viable Bifidobacterium longum, Lactobacillus delbrueckii bulgaricus, and Streptococcus thermophilus tablets from the 32nd week of pregnancy until delivery. The functional profiles of the gut microbiota were predicted through high-throughput 16S rRNA sequencing results using PICRUSt software and referencing the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. In the gut microbiota of the PG, the genera Blautia and Ruminococcus, as well as the species Subdoligranulum, showed significantly higher relative abundances compared to the control group (CG) (P < 0.05). At Level 1 of the KEGG signaling pathways, there was a significant reduction in the functional genes of the gut microbiota involved in Organismal Systems in the PG (P < 0.05). In Level 2 of the KEGG signaling pathways, there was a significant reduction in the functional genes of the gut microbiota involved in Infectious Disease in the PG (P < 0.05). In Level 3 of the KEGG signaling pathways, the PG exhibited a significant increase in the functional genes of the gut microbiota involved in ABC transporters, Oxidative phosphorylation, Folate biosynthesis, and Biotin metabolism (P < 0.05). The CG showed a significant increase in the functional genes related to Cysteine and methionine metabolism, Vitamin B6 metabolism, Tuberculosis, and Vibrio cholerae pathogenic cycle (P < 0.05). In conclusion, our findings suggest that probiotic supplementation during pregnancy has a significant impact on functional metabolism in healthy pregnant women. IMPORTANCE Probiotics are considered beneficial to human health. There is limited understanding of how probiotic consumption during pregnancy affects the functional diversity of the gut microbiota. The aim of our study is to investigate the impact of probiotic consumption during pregnancy on the functional diversity of the gut microbiota. Our findings suggest that probiotic supplementation during pregnancy has a significant impact on functional metabolism. This could potentially open up new avenues for preventing various pregnancy-related complications. This also provides new insights into the effects of probiotic consumption during pregnancy on the gut microbiota and offers a convenient method for exploring the potential mechanisms underlying the impact of probiotics on the gut microbiota of pregnant women.

Abstract
As the demand for automotive materials grows more stringent in environmental considerations, it becomes imperative to conduct thorough environmental impact assessments of dual-phase automotive strip steel (DP steel). However, the absence of detailed and comparable studies has left the carbon footprint of DP steel and its sources largely unknown. This study addresses this gap by establishing a cradle-to-gate life cycle model for DP steel, encompassing on-site production, energy systems, and upstream processes. The analysis identifies and scrutinizes key factors influencing the carbon footprint, with a focus on upstream mining, transportation, and on-site production processes. The results indicate that the carbon footprint of DP steel is 2.721 kgCO2-eq/kgDP, with on-site processes contributing significantly at 88.1%. Sensitivity analysis is employed to assess the impact of changes in resource structure, on-site energy, CO2 emission factors, and byproduct recovery on the carbon footprint. Proposals for mitigating carbon emissions in DP steel production include enhancing process gas recovery, transitioning to cleaner energy sources, and reducing the hot metal-to-steel ratio. These findings offer valuable insights for steering steel production towards environmentally sustainable practices.

Abstract
For embryo implantation and fetal development, the maternal immune system undergoes dramatic changes. The mechanisms involved in inducing alterations of maternal immunity have not been fully clarified. Gut microbiome and metabolites were thought to influence the host immune response. During normal pregnancy, notable changes occur in the gut microbiota and metabolites. However, the relationship of these alterations to immune function during pregnancy remains unclear. In this study, we examined gut microbiota, fecal metabolites, plasma metabolites, and cytokines in pregnant women and non-pregnant women. Our findings revealed that, in comparison to non-pregnant women, pregnant women exhibit a significant increase in the relative abundance of Actinobacteriota and notable differences in metabolic pathways related to bile acid secretion. Furthermore, there was a marked reduction in pro-inflammatory cytokines levels in pregnant women. Correlation analyses indicated that these alterations in cytokines may be linked to specific gut bacteria and metabolites. Bacteria within the same microbial modules exhibited consistent effects on cytokines, suggesting that gut bacteria may function as functional groups. Mediation analysis further identified that certain bacteria might influence cytokines through metabolites, such as bile acids and arachidonic acid. Our findings propose potential biological connections between bacteria, metabolites, and immunity, which require further validation in future studies.IMPORTANCEA great number of studies have focused on diseases induced by intestinal microecological disorders and immune imbalances. However, the understanding of how intestinal microbiota interacts with immunity during normal pregnancy, which is fundamental to studying pathological pregnancies related to intestinal microbiota disturbances, has not been well elucidated. Our study employed multi-omics analysis to discover that changes in gut microbiota and metabolites during pregnancy can impact immune function. In addition, we identified several metabolites that may mediate the effect of gut microbes on plasma cytokines. Our study offered new insights into our understanding of the connections between the gut microbiome, metabolome, and the immune system during pregnancy.

Abstract
Archaeal NurA protein plays a key role in producing 3'-single stranded DNA used for homologous recombination repair, together with HerA, Mre11, and Rad50. Herein, we describe biochemical characteristics and roles of key amino acid residues of the NurA protein from the hyperthermophilic euryarchaeon Thermococcus barophilus Ch5 (Tba-NurA). Tba-NurA possesses 5'-3' exonuclease activity for degrading DNA, displaying maximum efficiency at 45 °C-65 °C and at pH 8.0 in the presence of Mn2+. The thermostable Tba-NurA also possesses endonuclease activity capable of nicking plasmid DNA and circular ssDNA. Mutational data demonstrate that residue D49 of Tba-NurA is essential for exonuclease activity and is involved in binding ssDNA since the D49A mutant lacked exonuclease activity and reduced ssDNA binding. The R96A and R129A mutants had no detectable dsDNA binding, suggesting that residues R96 and R129 are important for binding dsDNA. The abolished degradation activity and reduced dsDNA binding of the D120A mutant suggest that residue D120 is essential for degradation activity and dsDNA binding. Additionally, residues Y392 and H400 are important for exonuclease activity since these mutations resulted in exonuclease activity loss. To our knowledge, it is the first report on biochemical characterization and mutational analysis of the NurA protein from Thermococcus.

Abstract
Fatty acid binding proteins (FABPs) play an important role as endogenous cytoprotectants. However, studies on FABPs in invertebrates are scarce. Previously, we discovered Bombyx mori fatty acid binding protein 1 (BmFABP1) through co-immunoprecipitation. Here, we cloned and identified BmFABP1 from BmN cells. The results of immunofluorescence indicated that BmFABP1 was localized in the cytoplasm. The tissue expression profile of silkworms showed that BmFABP1 was expressed in all tissues except hemocytes. The expression level of BmFABP1 gradually decreases in BmN cells and B. mori larvae after infection with B. mori nucleopolyhedrovirus (BmNPV). Upregulation of BmFABP1 expression through overexpression or WY14643 treatment significantly inhibited the replication of BmNPV, while downregulation of BmFABP1 expression by RNA interference promoted the replication of BmNPV. The same results were obtained in experiments on silkworm larvae. These results suggest that BmNPV induces BmFABP1 downregulation to promote its proliferation and that BmFABP1 has a potential anti-BmNPV role. This is the first report on the antiviral effect of BmFABP1 in silkworms and provides new insights into the study of the FABP protein family. Also, it is important to study BmNPV resistance in silkworms to breed transgenic silkworms with BmNPV resistance.

Abstract
In recent years, it has become evident that early-life intestinal flora plays a pivotal role in determining human health. Consequently, it is imperative to explore the establishment of neonatal intestinal flora and its influencing factors. Early neonatal intestinal flora is influenced by a multitude of factors, including maternal and infant-related factors, as well as external environment. This review summarizes the colonization mechanism of intestinal flora in the early life of newborns and discussed their influence on the establishment of neonatal intestinal flora, taking into account factors such as delivery mode, gestational age and feeding mode. Additionally, this review delves into the natural or artificial reconstruction of intestinal flora colonization defects in infants born via cesarean section and premature infants, with the goal of establishing a theoretical foundation for preventing and treating issues related to neonatal intestinal flora colonization and associated diseases.

Abstract
BACKGROUND The relationship between preoperative frailty and pulmonary complications after cardiac surgery in elderly patients is unclear. This study was designed to evaluate the relationship between frailty and postoperative pulmonary complications (PPCs) in elderly patients undergoing cardiac surgery and to provide a basis for their prevention and treatment. AIMS This study aimed to investigate the predictive value of preoperative frailty on pulmonary complications after cardiac surgery in elderly patients. METHODS Frailty was assessed using the CAF. The diagnosis of PPCs was based on the criteria defined by Hulzebos et al., and patients were classified into a PPCs group and a non-PPCs group. Factors with clinical significance and P < 0.05 in univariate regression analysis were included in multivariate logistic regression analysis to determine the relationship between preoperative frailty and PPCs. The area under the receiver operating characteristic (ROC) curve (AUC) was used to compare the predictive effects of the CAF, EuroSCORE II, and ASA + age on the occurrence of PPCs. RESULTS A total of 205 patients were enrolled in this study, 31.7% of whom developed PPCs. Univariate logistic regression analysis showed that frailty, ASA grade, EuroSCORE II, hemoglobin concentration, FVC, time of operation, and postoperative AKI were associated with the development of PPCs. However, after adjustments for all possible confounding factors, multivariate logistic regression results showed that frailty, prolonged operation time, and postoperative AKI were risk factors for PPCs, and the risk of postoperative PPCs in frail patients was approximately 4.37 times that in nonfrail patients (OR = 4.37, 95%CI: 1.6-11.94, P < 0.05). The predictive efficacy of the traditional perioperative risk assessment tools EuroSCORE II and ASA + age was lower than that of CAF. CONCLUSIONS Frailty before surgery, prolonged operation time, and postoperative AKI were independent risk factors for pulmonary complications after heart surgery in elderly individuals, and CAF was more effective than the traditional risk predictors EuroSCORE II and ASA + age.

Abstract
The effects of probiotics on the gut microbiota in maternal mice-fed high-fat diet (HFD) during pregnancy and offspring are still unknown. We aimed to evaluate the effect of high-fat diet and probiotic supplementation on the gut microbiota of maternal mice at term pregnancy and offspring at three-week postpartum. Female pregnant Kunming mice were randomly divided into four groups: mice on a control diet (MC), mice on HFD (MHF), mice on a control diet and probiotics (MCP), and mice on HFD and probiotics (MHFP). The result showed that MHF had significantly reduced Bacteroidetes and Muribaculaceae (P < 0.05) and increased Firmicutes/Bacteroidetes ratio vs. MC. Lachnospiraceae_NK4A136_group and Alistipes reduced (P < 0.05), and Firmicutes/Bacteroidetes ratio significantly increased in MCP vs. MC. There was no significant difference between MHF and MHFP. Higher levels of Prevotella, Prevotellaceae, and Streptococcaceae were found in mice offspring on HFD (OHF) vs. mice offspring on a control diet (OC) (P < 0.05, respectively). Bacteroidia, Bacteroidota, Bacteroidales, and Muribaculaceae decreased markedly in mice offspring on a control diet and probiotics (OCP) vs. OC (P < 0.05, respectively), while Firmicutes, Lactobacillales, Lactobacillaceae, and Lactobacillus significantly increased in OCP (P < 0.05, respectively). There was no significant difference between the OHF and mice offspring on HFD and probiotics (OHFP). The findings suggest that the gut microbial composition of pregnant mice and offspring were altered to some extent due to HFD or probiotic intervention. Further, maternal mice on HFD and offspring were less affected by probiotic supplementation.

Abstract
Purpose To investigate the diagnostic value of 18F-fluorodeoxyglucose positron emission tomography (18F-FDG PET), as an imaging biomarker, for predicting pathological response and prognosis of unresectable hepatocellular carcinoma (HCC) patients treated with Lenvatinib and programmed cell death protein 1 (PD-1) inhibitors as a conversion therapy. Methods A total of 28 unresectable HCC patients with BCLC stage B or C were treated with Lenvatinib and PD-1 inhibitors before surgery. The 18F-FDG PET/CT scans were acquired before pre- (scan-1) and post-conversion therapy (scan-2). The maximum standardized uptake value (SUVmax), TLR (tumor-to-normal liver standardized uptake value ratio), and the percentages of post-treatment changes in metabolic parameters (ΔSUVmax [%] and ΔTLR [%]) were calculated. Major pathological response (MPR) was identified based on the residual viable tumor in the resected primary tumor specimen (≤10%). Differences in the progression-free survival (PFS) and overall survival (OS) stratified by ΔTLR were examined by the Kaplan-Meier method. Results 11 (11/28, 39.3%) patients were considered as MPR responders and 17 (17/28, 60.7%) patients as non-MPR responders after conversion therapy. ΔSUVmax (-70.0 [-78.8, -48.8] vs. -21.7 [-38.8, 5.7], respectively; P<0.001) and ΔTLR (-67.6 [-78.1, -56.8] vs. -18.6 [-27.9, 4.0], respectively; P<0.001) were reduced in the responder group than those in the non-responder group. According to the results of the receiver operating characteristic curve analysis, ΔTLR showed an excellent predictive value for the MPR of primary HCC lesions (area under curve=0.989, with the optimal diagnostic threshold of -46.15). When using ΔTLR of -21.36% as a threshold, patients with ΔTLR-based metabolic response had superior PFS (log-rank test, P=0.001) and OS (log-rank test, P=0.016) compared with those without ΔTLR-based metabolic response. Conclusion 18F-FDG PET is a valuable tool for predicting pathological response and prognosis of unresectable HCC patients treated by Lenvatinib combined with PD-1 as a conversion therapy.

Abstract
Endonuclease Q (EndoQ) can effectively cleave DNA containing deaminated base(s), thus providing a potential pathway for repair of deaminated DNA. EndoQ is ubiquitous in some Archaea, especially in Thermococcales, and in a small group of bacteria. Herein, we report biochemical characteristics of EndoQ from the hyperthermophilic euryarchaeon Thermococcus gammatolerans (Tga-EndoQ) and the roles of its six conserved residues in DNA cleavage. The enzyme can cleave uracil-, hypoxanthine-, and AP (apurinic/apyrimidinic) site-containing DNA with varied efficiencies at high temperature, among which uracil-containing DNA is its most preferable substrate. Additionally, the enzyme displays maximum cleavage efficiency at above 70 oC and pH 7.0 ∼ 8.0. Furthermore, Tga-EndoQ still retains 85% activity after heated at 100 oC for 2 hrs, suggesting that the enzyme is extremely thermostable. Moreover, the Tga-EndoQ activity is independent of a divalent ion and NaCl. Mutational data demonstrate that residues E167 and H195 in Tga-EndoQ are essential for catalysis since the E167A and H195A mutants completely abolish the cleavage activity. Besides, residues S18 and R204 in Tga-EndoQ are involved in catalysis due to the reduced activities observed for the S18A and R204A mutants. Overall, our work has augmented biochemical function of archaeal EndoQ and provided insight into its catalytic mechanism.

Abstract
In the current study, we assessed the relationship between mutations and the blood cell counts and early progression of patients with diffuse large-B cell lymphoma (DLBCL). A total of 109 patients with newly diagnosed DLBCL were included in this study. UBE2A mutation was only found in patients with bone marrow involvement. The mutations of ZNF608, SF3B1, DTX1, and NCOR2 were related to blood cell counts. NCOR2 mutations were only detected in patients of the noncomplete response group (PR + SD + PD). In addition, the mutations of ATM, BTG2, TBL1XR1, and TP53 were linked to lower PFS/OS rate, while SGK1, SCOS1, and NFKBIE were related to higher PFS/OS rate. Importantly, we identified that Ann Arbor stage (III-IV), B symptoms, absolute lymphocyte count (ALC) abnormity, and MTOR mutation were the four independent influencing factors of the 12-month progression of DLBCL patients. Overall, this study revealed that mutations were associated with the early progression of DLBCL.

Abstract
The silkworm, Bombyx mori, a model Lepidopteran specie, is an important economic insect. It is specifically infected by Bombyx mori nucleopolyhedrovirus (BmNPV), causing huge losses to the sericulture industry. Therefore, the understandings of the interaction mechanism between BmNPV and the host will help to provide the theoretical basis for the sericulture industry to control BmNPV. Apolipoprotein D (ApoD) is a member of lipid transport family and capable of binding to a variety of lipophilic ligands. ApoD is mainly used in neurodegenerative disease research in mammals, and there is little research on ApoD against viruses. Here, we explored the effects of Bombyx mori Apolipoprotein D (BmApoD) on BmNPV replication. We knocked out and overexpressed BmApoD in BmN cells and infected them with Bombyx mori nucleopolyhedrovirus (BmNPV). The results showed that BmApoD promote the replication of BmNPV in BmN cells. It was also confirmed that BmApoD promote the replication of BmNPV after knocking down BmApoD in silkworm larvae. This study is the first to explore the role of ApoD in insect-virus interactions, providing new insights into the functional role of ApoD.

Abstract
Objective: To evaluate the intervention effect of various drugs on glutathione (GSH) and superoxide dismutase (SOD) enzyme activity of rats kidney with acute nickel carbonyl poisoning. Methods: In January 2019, The 250 SPF male SD rats were randomly divided into normal control group (n=10) , poisoned group (n=40) and treatment groups (n=200) according to the random number table method. And the treatment groups were divided into methylprednisolone group (20 mg/kg) , DDC group (100 mg/kg) , sodium selenite group (10 μmol/kg) , Shenfu huiyang decoction group (0.25 ml) and methylprednisolone combined with DDC group (100 mg/kg) , with 40 mice in each group. Except for the normal control group, rats in the other groups were exposed to nickel carbonyl for 30 min, at 4 h and 30 h after exposure, the rats in each treatment group were intraperitoneally injected with corresponding drugs, and kidney tissues were collected 3 d and 7 d after administration, with 10 mice in each group. The activities of GSH and SOD in kidney were measured by enzyme-linked immunosorbent assay, and using electron microscopy observe ultrastructure changes. Results: Compared to the control group, the activities of GSH and SOD enzyme of poisoned group were significantly decreased at 3 d or 7 d after 4 h or 30 h exposure, and the difference was statistically significant (P=0.000, 0.031, 0.001, 0.033) , the epithelial nuclei of proximal convoluted tubules were pyknosis and lysosome hyperplasia in the cytoplasm. And compared to poisoned group, the activities of GSH and SOD enzyme of methylprednisolone+DDC group were significantly increased at treatment with 7 d after 4 h exposure, the difference was statistically significant (P=0.022, 0.000) , and the activities of GSH and SOD enzyme of methylprednisolone and enzyme of methylprednisolone+DDC group were significantly higher at 7 days than at 3 days, the difference was statistically significant (P=0.020, 0.017, 0.018, 0.033) . The results of electron microscopy showed that the cell nuclei and cytoplasmic organelles of proximal convolute tubule were almost restored to normal tissue level of both methylprednisolone group and methylprednisolone+DDC group. Conclusion: The methylprednisolone and methylprednisolone+DDC have obvious repair effect on renal enzyme activity level of rats with acute nickel carbonyl poisoning, and the treatment effect is better for a long time of medication.

Abstract
Objectives This study aimed to assess the pretreatment 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) as a predictor of the pathological treatment response (PTR) of hepatocellular carcinoma (HCC) patients treated with PD-1 inhibitors and lenvatinib as a conversion therapy in BCLC stage C. Methods All patients (n=20) underwent pretreatment 18F-FDG PET/CT and were treated with conversion therapy and surgery. Patients were categorized into responders (n=9) and non-responders (n=11) according to PTR. The parameters of PET/CT, including lesion size, SUVmean (mean standard uptake value), MTV (metabolic tumor volume), TLG (total lesion glycolysis), SUVpeak (peak standard uptake value), and TLR (tumor-to-normal liver standardized uptake value ratio), were calculated. The diagnostic efficacy was evaluated by receiver operating characteristic analysis (ROC). PTR was compared with pretreatment PET/CT parameters by using Spearman correlation analysis. The patients were followed up. Results There was significant difference in TLR (5.59 ± 1.90 vs. 2.84 ± 1.70, respectively; P=0.003) between responders and non-responders, with the largest area under the curve (sensitivity=100%, specificity=72.7%, AUC=0.899, 95%CI: 0.759-1.000, optimal diagnostic threshold of 3.09). The relationship between 18F-FDG PET/CT parameters and PTR indicated TLR was moderately and positively correlated with pathological treatment response, with correlation coefficients (rs) of 0.69 (P<0.01). During the follow-up, no patients died, and tumor recurrence was found in one of the responders (11.1%). In all 11 non-responders, tumor recurrence was found in six patients (54.5%) and four patients (36.4%) died. Conclusions TLR may be a powerful marker to predict PTR of HCC patients with BCLC stage C who were treated with conversion therapy.

Abstract
e16130 Background: Current systemic therapy for patients with hepatocellular carcinoma (HCC) in BCLC stage C consists of tyrosine kinase inhibitors (TKIs) and immune checkpoint inhibitors (ICIs). This study aimed to assess the parameters of pretreatment 18F-FDG PET/CT as a predictor of the pathological treatment response (PTR) of HCC patients treated with PD-1 inhibitors and lenvatinib as a conversion therapy in BCLC stage C. Methods: We retrospective analyzed 20 consecutive patients with HCC in BCLC stage C. All patients underwent pretreatment 18F-FDG PET/CT and treated with PD-1 inhibitors and lenvatinib as a conversion therapy and surgery. Patients were categorized into responders (n=9) and non-responders (n=11) according to PTR. The PTR was classified based on the primary tumor cellularity (responder, defined as <10% cellularity). The parameters of PET/CT including lesion size, SUVmax (max standardized uptake value), SUVmean (mean standard uptake value), MTV2.5 (metabolic tumor volume2.5), TLG2.5 (total lesion glycolysis2.5), SUVpeak (peak standard uptake value), and TLR (tumor-to-normal liver standardized uptake value ratio, SUVmax of the tumor/SUVmean of the normal liver parenchyma) were calculated and compared between two groups. The diagnostic efficacy was evaluated by ROC. PTR was compared with pretreatment 18F-FDG PET/CT parameters by using Spearman correlation analysis. The prognosis was followed up. Results: TLR (5.59±1.90 vs. 2.84±1.70, respectively; P=0.003) showed significant difference in responders and non-responders and the largest area under the curve (sensitivity: 1.000, specificity: 0.727, positive predictive value: 0.750, negative predictive value: 1.000, AUC=0.899, 95%CI: 0.759-1.000), and optimal diagnostic threshold of 3.09. The relationship between 18F-FDG PET/CT parameters and PTR showed TLR had moderate positive correlation with pathological treatment response, with correlation coefficients (rs) of 0.69 ( P<0.05). During the follow-up, no patients died, and 1 patient (11.1%) showed tumor recurrence in responders. In all 11 non-responders, 5 patients (45.5%) had tumor recurrence and 4 patients (36.4%) died. Conclusions: The TLR may be a powerful marker to predict the PTR of HCC patients with BCLC stage C who treated with PD-1 inhibitors and lenvatinib as a conversion therapy.[Table: see text]

Abstract
Detection of arterial stiffness is an important method to predict the occurrence of hypertension complications and to screen patients with high cardiovascular risk. In order to predict the damage of AASI to the renal function of patients with essential hypertension, the prediction of AASI based on stepwise Regression equation scanning for renal function damage in patients with essential hypertension is proposed. Measure the 24 h ambulatory blood pressure of the selected subjects, establish a linear Regression equation scanning, and calculate the slope of the straight line, and finally, the slope is AASI. According to the quartiles, AASI is divided into four parts: group I < 0.53 (n = 49); 0.53 ≤ group II < 0.60 (n = 51); 0.60 ≤ group III < 0.69 (n = 48); group IV ≥ 0.69 (n = 44). Experiment result shows the following: with the increase of AASI, cystatin (CysC) also increased significantly, while CysC-eGFR decreased significantly (P < 0.05). Compared with groups I, II, and III, Scr and CysC in group IV increased (P < 0.05), and Ccr, CysC-eGFR, and (CKD-EPI)-eGFR all decreased (P < 0.05). AASI is positively correlated with CysC performance, and the correlation coefficient r is 0.637. It is negatively correlated with Ccr performance, and r is -0.361. It is negatively correlated with CysC-eGFR, and r is -0.698. And it is negatively correlated with (CKD-EPI)-eGFR, and r is -0.331. Age and 24 h PP also showed an increasing trend with the increase of AASI, and it suggests that age may be an influencing factor that promotes kidney damage caused by hypertension; it also suggests that AASI can be used as a new indicator of arterial compliance; AASI is linearly related to various indicators of renal damage and can be used as a predictive indicator of renal damage caused by essential hypertension; cystatin C and the estimated glomerular filtration rate CysC-eGFR based on cystatin C are better than other indicators reflecting glomerular filtration rate, more sensitively assess the degree of early renal damage. Obesity may also be a factor that promotes kidney damage caused by hypertension.

Abstract
Explore the pathogenesis and influencing factors of adult hypertension based on structural equation scanning. Using a multistage random sampling method, randomly select 2 community health service centers in each administrative area of a certain city and conduct a sample survey of residents in the community. According to the predetermined sample size n, multiply by 1.3 (1.3n) to draw a sample. Community doctors and medical students who have been uniformly trained form an investigation team draw up a questionnaire by consulting the literature, seek expert opinions, and then make changes based on the questions in the preinvestigation. Experiment result shows that the average systolic blood pressure of the experimental subjects was 126.13 + 15.36 mmHg and the average diastolic blood pressure was 79.52 + 8.81 mmHg; males are higher than females and increase with age. The prevalence rate of hyperemia is 26.3%, and the prevalence rate of prehypertension among the survey subjects is 55.4%; that of males (62.6%) is higher than that of females (49.2%). The prevalence of isolated systolic hypertension was 7.5%, and that of men (6.9%) was lower than that of women (7.9%). The awareness rate of hypertension was 66.5%, and the treatment rate of hypertension was 62.7%; the control rate of hypertension was 13.2%, and the control rate of hypertension treatment was 25.7%; all the abovementioned rates are higher for women than for men, and they all tend to increase with age which proved that being overweight is a risk factor for hypertension, dyslipidemia, and hypertension. Hypertension, dyslipidemia, and family history of hypertension are risk factors for hypertension. There is a positive correlation between hypertension and dyslipidemia.

Abstract
Designing non-precious metal electrocatalysts for accelerated electron transfer and richer active site exposure is necessary and challenging to achieve the versatility of electrocatalysts. In this research, a self-grown nanosheet array electrocatalyst on nickel foam with high structural stability is first rationally designed through suitable anionic doping. The combined experimental and theoretical calculations reveal that the F-P-Co3O4/NF material optimizes the adsorption energy of hydrogen/water through electron coupling, and its nanosheet structure provides abundant active sites, accelerating the mass and electron transfer in the reaction process. It is worth noting that the as-developed F-P-Co3O4/NF materials exhibit outstanding catalytic activity for overpotentials of 192 and 110 mV at a current density of 10 mA cm-2 for the oxygen evolution reaction and the hydrogen evolution reaction in 1 M KOH, respectively. More notably, an assembled F-P-Co3O4/NF//F-P-Co3O4/NF alkaline electrolytic cell requires only an ultra-low cell voltage of 1.53 V to achieve a current density of 10 mA cm-2, which is one of the best activities reported so far. Furthermore, F-P-Co3O4/NF also shows excellent performance for urea electrolysis. Theoretical calculations show that the superior activity of the F-P-Co3O4/NF catalyst is attributed to the optimal electron configuration and the lower Gibbs free energy of hydrogen adsorption due to co-doping of P and F. The work provides an alternative solution for the preparation of electrocatalysts with high structural stability, high catalytic activity and multifunction for alkaline water splitting and urea electrolysis.

Abstract
Background and Aims Immunotherapy with PD-1 inhibitors combined with tyrosine kinase inhibitors (TKIs) has been proven to be effective against advanced hepatocellular carcinoma (HCC). The aim of this study was to identify the feasibility and safety of subsequent salvage surgery after this combination therapy. Methods and Patients A retrospective analysis was performed on patients with primary HCC with major vascular invasion between 2018 and 2019. All cases were treated with a combination of a PD-1 inhibitor and TKI agents and subsequent surgery. Results A total of 10 HCC cases with major vascular invasion met the successful conversion criteria after the combination therapy, and eight patients underwent subsequent salvage surgery after both radiology and 3D quantitative oncological assessment. Partial response (PR) was recorded in 7 of 10 patients and complete response (CR) in 3 of 10 patients before salvage surgery. Salvage surgery included right hepatectomy, left hepatectomy, and anatomic segmental hepatectomy. The mean intraoperative blood loss was 1,650 ml (50–3,000 ml). No complications beyond Clavien–Dindo level III or postoperative mortality were observed. The viable tumor cell rate of the PR cases (modified response evaluation criteria in solid tumors, mRECIST) varied from 1.5% to 100%, and only one patient had pathology-proven pathological complete response (pCR). The postoperative median follow-up time was 19.7 months (9.1–24.9 months). The 12-month recurrence-free survival rate of all cases who underwent salvage surgery was 75%. Conclusion Salvage surgery was effective and safe after conversion therapy with PD-1 inhibitors plus TKIs and may increase the long-term oncological benefit for patients with unresectable HCC.

Abstract
The design and synthesis of hybrid core-shell catalysts is of great significance for obtaining an excellent performance of hydrogen evolution reaction (HER). However, it remains a challenge to explore the exact active sites and research the catalytic mechanism for HER. Here, a series of Ni3S2@MOOH/NF (M = Fe, Ni, Cu, Mn and Co) hybrid structures is firstly in-site grown on Ni foam by the typical hydrothermal and electrodeposition methods. The Ni3S2@NiOOH/NF catalyst with a core-shell structure exhibits a relatively low overpotential of 79 mV for HER at a current density of 10 mA cm-2, which is one of the best catalytic activities reported so far. Moreover, it also shows good stability in the long-term durability test. Various spectral analysis and density functional theory calculations demonstrate that NiOOH is favorable for the adsorption of water molecules, and the S atom at the interface between Ni3S2 and NiOOH is favorable for the adsorption of H intermediates, which strongly accelerates the HER process in alkaline solution. This work provides a general strategy for the synthesis of electrocatalytic materials, which can be used for efficient electrocatalytic water splitting reactions.

Methods: select 228 patients with acute organophosphorus pesticide poisoning in our hospital from October 2017 to March 2020. According to the grade of poisoning degree, it was divided into 82 cases in mild and moderate group and 146 cases in severe group. hs-cTnI、CK-MB、sST2、NT-proBNP、APACHE Ⅱ score and cholinesterase activity were detected 4 h、12 h、24 h after admission. ROC curve was used to evaluate sST2 and NT-proBNP to predict the prognosis of AOPP. Results: 4 hours after admission, there was no significant difference in the scores of hs-cTnI, APACHE Ⅱ, cholinesterase and CK-MB between the Severe Group and the mild and moderate Group (P<0.05) . At 12 and 24 hours after admission, the scores of hs-cTnI, CK-MB and APACHE Ⅱ in severe group were higher than those in mild and moderate group, and the changes of Cholinesterase were more significant than those in 12 hours after Admission (P<0.05) . 4 hours after admission, SST2 and NT-proBNP levels were significantly higher in severe group than those in mild and moderate Group (P<0.05) . The level of SST2 and NT-proBNP in the severe group was significantly higher than that in the mild and moderate group 12 and 24 hours after Admission (P<0.01) , and the level of SST2 and NT-proBNP was significantly higher than that in the mild group 12 hours after Admission (P<0.05) . Correlation analysis showed that 24 hours after admission, sST2, NT-proBNP were positively correlated with APACHE-Ⅱ scores (R=0.634, 0.723, P<0.01) . The area under sST2 combined with NT-proBNP was 0.891, higher than that under sST2 and NT-proBNP at 12 h after admission. The 24 h APACHE Ⅱ score after admission area under the curve was 0.838. Conclusion: sST2 and NT-proBNP combined detection can early predict the occurrence of recent complications in AOPP patients.

Abstract
The development of high-performance and cost-effective bifunctional water splitting catalysts has enormous significance in the hydrogen production industry from water electrolysis. Herein, an in situ Co and N co-doping method was developed to improve the electrocatalytic performance of Ni3S2 catalysts. The Co-N-Ni3S2/NF is successfully synthesized for the first time by a one-step hydrothermal method, wherein nickel foam, thioacetamide and Co(NO3)2·6H2O are used as the nickel source, sulfur source, nitrogen source and cobalt source. Co-N-Ni3S2/NF exhibits excellent oxygen evolution reaction activity (an overpotential of 285 mV@50 mA cm-2) and hydrogen evolution reaction activity (an overpotential of 215 mV@10 mA cm-2) in 1 M KOH solution. The electrolytic cell displayed a low cell voltage of 1.50 V when the Co-N-Ni3S2/NF material was used as the bifunctional water splitting electrocatalyst, which is one of the best catalysts reported so far. Density functional theory calculations show that Co-N-Ni3S2/NF exhibits stronger water adsorption energy than those of N-Ni3S2/NF, Co-Ni3S2/NF and Ni3S2/NF. It is proved that the doping of Co and N can effectively regulate the electron cloud density of Ni, thus enhancing the electrochemical activity of Co-N-Ni3S2/NF.

Abstract
Background This retrospective study was performed to estimate the clinical role of whole-body positron emission tomography/computed tomography (PET/CT) using 2-[18F] fluoro-2-deoxy-D-glucose (FDG) in the differential diagnosis of primary benign and malignant unilateral adrenal tumors. Methods A total of 64 patients (31 male, 33 female; age range: 3-76 years, mean: 48.5) with a confirmed unilateral adrenal tumor underwent 18F-FDG PET/CT examination for diagnosis and staging. The whole-body 18F-FDG PET/CT examination excluded metastasis, and all patients were confirmed by operation and biopsy pathology. Their clinical data and pathological results were collected. On visual analysis of PET/CT imaging, adrenal uptake was based on a three-scale grading system. The region of interest (ROI) was delineated in the liver and the renal lesion site. Standardized uptake value (SUV) measurements were determined on a standardized reconstruction, and the maximum values (SUVmax) of the lesion and liver were measured. The ratio of tumor to the liver was defined as T/L. Visual interpretation, SUVmax-receiver operating characteristics (ROC) method, and T/L-ROC method were used to analyze the diagnostic accuracy. Results A total of 64 lesions (48 benign, 16 malignant lesions) were detected. The visual analysis found that 100% of Grade I cases were benign, 90.9% of Grade II cases were benign, and 65.1% of Grade III cases were benign. The SUVmax of malignant lesions (10.0±5.8) was higher than that of benign lesions (5.4±5.3, P<0.05). The T/L was 3.39±1.79 for malignant lesions and 1.99±2.09 for benign lesions (P<0.05). In the differentiation of primary benign and malignant unilateral adrenal tumors, the sensitivity, specificity, and accuracy of the SUVmax-ROC method (cut-off value =5.65) were 81.25%, 72.91%, 75.00%, and the positive and negative predictive values were 50.00% and 92.11%, respectively. The sensitivity, specificity, and accuracy of the T/L-ROC method (cut-off value =1.52) were 93.73%, 62.50%, 70.31%, and the positive and negative predictive values were 46.88% and 96.77%, respectively. Conclusions 18F-FDG PET/CT improved diagnostic accuracy in differentiating primary benign and malignant unilateral adrenal tumors. There was a high negative predictive value, and for positive prediction, other tracer imaging is needed for differential diagnosis.

Abstract
The development of highly efficient, inexpensive, abundant and non-precious metal electrocatalysts is the lifeblood of the hydrogen production industry, especially the hydrogen production industry by electrolysis of water. A Fe-Co-S/NF bifunctional electrocatalyst with nanoflower-like structure was synthesized on three-dimensional porous nickel foam through one-step hydrothermal and one-step high-temperature sulfuration operations, and the material displays high-efficiency electrocatalytic performance. As a catalyst for the hydrogen evolution reaction, Fe-Co-S/NF can drive a current density of 10 mA/cm2 at an overpotential of 143 mV with a Tafel slope of 80.2 mV/dec. When it was used as an oxygen evolution reaction catalyst, it exhibits good OER reactivity with a low Tafel slope (82.6 mV/dec) and with requiring only 117 mV overpotential to drive current densities up to 50 mA/cm2 . In addition, the Fe-Co-S/NF//Fe-Co-S/NF electrolytic cell was assembled, an electrolysis voltage of 1.64 V is required to drive a current density of 50 mA/cm2 , which is one of the most active catalysts reported so far. This work indicates that the introduction of S, P and Se treating processes could effectively improve electrical conductivity of the material and enhance the catalytic activity of the material. This work offers an effective and convenient method for improving the morphology of the catalyst, increasing the surface area of the catalyst and developing high-efficiency and low-cost catalysts.

Abstract
Diabetic nephropathy (DN) is one of the most severe complications that can occur in patients with diabetes, and without effective and timely therapeutic intervention, can gradually progress to renal failure. Previous studies have focused on investigating the pathogenesis of DN; however, the role of dual‑specificity phosphatase 6 (DUSP6) in DN is not completely understood. Therefore, the present study aimed to investigate the role of dual‑specificity phosphatase 6 (DUSP6) in DN. DN model mice were established and the expression levels of DUSP6 in the kidney tissues and high glucose (HG)‑induced murine podocytes (MPC5 cells) were determined using immunohistochemistry, reverse transcription‑quantitative PCR and western blotting. In addition, the levels of reactive oxygen species (ROS) and inflammatory cytokines in MPC5 cells were analyzed using commercial assay kits or ELISA kits, respectively, and flow cytometric analysis was performed to analyze the rate of cell apoptosis. The present study indicated that DUSP6 expression levels were significantly decreased in DN model mice compared with control mice, and in HG‑induced MPC5 cells compared with normal glucose‑induced MPC5 cells. DUSP6 overexpression enhanced MPC5 cell viability and increased protein expression levels of cell markers, such as synaptopodin and nephrin, compared with the negative control group. DUSP6 overexpression also reduced the levels of ROS and inflammatory cytokines, including interleukin (IL)‑1β, IL‑6 and tumor necrosis factor‑α secreted by MPC5 cells under HG conditions. Moreover, compared with the HG group, cell apoptosis was inhibited by DUSP6 overexpression under HG conditions, which was further indicated by decreased expression levels of cleaved caspase‑3 and Bax. Thus, these findings indicated that DUSP6 mediated the protection against HG‑induced inflammatory response.

Abstract
e20066 Background: To evaluate the efficacy and safety of pegylated recombinant human granulocyte-colony stimulating factor (PEG-rhG-CSF) and recombinant human granulocyte-colony stimulating factor (rhG-CSF) in patients with lymphoma. Methods: This retrospective study included patients with newly diagnosed lymphoma who received CHOP ± R (cyclophosphamide, doxorubicin, vincristine, prednisone ± rituximab) between January 2014 to October 2018. PEG-rhG-CSF(brand name: jinyouli) was injected subcutaneously once 24-72 hours after chemotherapy as primary prevention. rhG-CSF was used as prevention or treatment. The primary endpoint was the incidence of febrile neutropenia (FN), and the secondary endpoints included the incidence of grade III/IV neutropenia, the incidence of chemotherapy dose adjustment, the incidence of chemotherapy delay, the rate of antibiotics application and safety. Results: 178 patients with lymphoma were included, of which 76 were in the PEG-rhG-CSF group (256 cycles) and 102 were in the rhG-CSF group (336 cycles). The incidence of FN was 1.17% (3/256) in the PEG-rhG-CSF group and 5.95% (20/336) in the rhG-CSF group, P= 0.003. The incidence of grade Ⅲ/Ⅳ neutropenia and chemotherapy delay in the PEG-rhG-CSF group were significantly lower than those in the rhG-CSF group (12.89%[33/256] vs 50.30%[169/336], P < 0.0001; 3.13%[8/256] vs 9.52% [32/336], P= 0.002). However, there was no significant difference between the two groups in the incidence of dose adjustment (6.25% vs 3.57%, P = 0.128) and the rate of antibiotics application (34.77% vs 33.33%, P= 0.715). And there was no significant difference in the incidence of fever, bone pain and fatigue between the two groups. Conclusions: Compared with rhG-CSF, prophylactic use of PEG-rhG-CSF can significantly reduce the incidence of FN, grade III/IV neutropenia and chemotherapy delay in patients with lymphoma with good safety.

Abstract
PURPOSE To investigate the features of 18F-Fluoro-D-glucose positron emission tomography/computed tomography (18F-FDG PET/CT) in differentiating synchronous multiple primary lung cancers (sMPLC) from intropulmonary metastasis (IM). MATERIAL AND METHODS Fifty-nine patients with two synchronous primary lung cancers were selected and 23 lung cancer patients with an additional solitary IM cancer were chosen as the control group between January 2009 and January 2019. Maximum standardized uptake values (SUVmax) on PET/CT was determined for each tumor. The SUVmax ratio between the two tumors was determined and receiver operating characteristic curve analysis was used to evaluate the diagnostic performance. RESULTS The difference of SUVmax ratio between sMPLC (2.3 ± 1.6) and IM (1.5 ± 0.4) was significant, p < 0.01; the area under the curve of the SUVmax ratio was 0.78 with the optimal cutoff value 1.7 (sensitivity 62.7% and specificity 82.6%, p < 0.001). CONCLUSION The SUVmax ratio between two tumors may be helpful in differentiating sMPLC from IM, independent studies with bigger size were needed to further confirm the findings.

Abstract
Although Ni phosphides are efficient for hydrogen evolution reactions, they are unfavorable for oxygen evolution reactions, so their application in alkaline water electrolysis is limited. It is a feasible method for creating a novel Ni phosphide/oxide heterogeneous interface to promote the oxygen evolution kinetics of Ni phosphide materials in an alkaline medium, yet it has been an unprecedented challenge for researchers. In this work, NiP3@CeO2 hybrid nanoparticles are firstly in situ grown on Ni foam (NiP3@CeO2/NF) via a novel controlled phosphating strategy. The NiP3@CeO2/NF catalysts display a fairly small overpotential of 200 mV to achieve a current density of 25 mA cm-2 for the oxygen evolution reaction (OER) under alkaline conditions, 110 mV smaller than that of NiO@CeO2/NF. It is noteworthy that the improved electrocatalytic performance of NiP3@CeO2/NF can be attributed to rapid electron transfer and the synergistic catalytic effect of the hybrid material. Density functional theory results demonstrate that NiP3 shows a stronger water adsorption energy than CeO2. The novel strategy of controlled phosphating to construct transition metal phosphide/oxide interfaces provides new ideas and methods for the development of efficient and practical water splitting catalysts.

Abstract
Background This study was performed to examine the effect of non-synchronization of the radiotracer injection and image acquisition on estimates of the glomerular filtration rate (GFR) by the Gates' method. Methods A total of 218 volunteers were selected as the research subjects. Two-sample method (GFRdt) and 99mTc-DTPA dynamic renal imaging (GFRGates) were used for determination of the GFR. We took GFRdt as the reference method, and then took the peak time of blood perfusion phase as the new time origin to ensure that all patients were unified on the time-radioactivity count rate curve. We moved the radioactivity curve on 9 time points to simulate premature (+20/+15/+10/+5 seconds), synchronous (0 seconds), and delayed (-20/-15/-10/-5 seconds) image acquisition in relation to the completion of tracer injection; we then acquired 9 GFRGates. The correlation and consistency of GFRGates and GFRdt were analyzed. Variance analysis compared the differences between different GFRGates. Results All 9 GFRGates had good correlation with GFRdt. GFRdt and GFRGates derived from -5, -10 and -15 s had the best correlation (r=0.827, P<0.01). The consistency between GFRGates derived from +20 s and GFRdt was the worst, and GFRGates derived from -15 s and GFRdt was the best. There were no significant differences between the 9 GFRGates. Conclusions Non-synchronization of the radiotracer injection and image acquisition has no significant effect on the estimates of the GFRGates if the premature or delayed time between image acquisition and tracer injection is not more than 20 seconds.

Abstract
This study was performed to develop a new formula to estimate the renal and isthmus depth in horseshoe kidney, and to compare the new formula with previously published formulas.Renal depth, isthmus depth, vertebral thickness, and total thickness (T, cm) of the body at the level of the kidneys were measured by CT in 124 adults. Their sex, age, height (H, cm), and weight (W, kg) were recorded. Multiple stepwise linear regression analysis was conducted. The 124 cases were divided into 2 random groups, of which the first group was used to derive a regressive formula and the second group was used to verify the formula and compare the formula with previously published formulas.Multiple stepwise linear regression analysis showed that the important variables in estimating the depth of each kidney were the body weight (W, kg) and the total thickness (T, cm) of the body at the level of the kidneys. The important variables in estimating the depth of isthmus soft tissue and vertebral thickness were W, T, and age, W. The new formula was the following: right renal depth (cm) = 0.273 × T + 0.043 × W + 1.086 (r = 0.82, P < .05; standardized regressive coefficient: T = 0.500, W = 0.367), left renal depth (cm) = 0.245 × T + 0.041 × W + 0.676 (r = 0.83, P < .05; standardized regressive coefficient: T = 0.520, W = 0.353); isthmus depth (cm) = soft tissue depth + vertebral thickness, soft tissue depth (cm) = 0.144 × T + 0.044 × W + 0.536 (r = 0.58, P < .05; standardized regressive coefficient: T = 0.272, W = 0.335), vertebral thickness (cm) = 0.012 × age + 0.018 × W + 3.683 (r = 0.53, P < .05; standardized regressive coefficient: age = 0.326, W = 0.438). It is much better than the literatures.The new renal depth estimation formula in horseshoe kidney that we derived by using multiple stepwise linear regression has greatly outperformed other 6 previously published formulas. Isthmus depth estimation formula can also get accurate results. Our new formula provides a more reliable and accurate renal and isthmus depth estimation and contributes to improving the methods used to estimate renal function from radionuclide renography in horseshoe kidney.

Abstract
The ban on the use of antibiotic feed additives as growth promoters compelled the researchers for exploring the future utility of other alternatives. This experiment was designed to evaluate the effect of acidified drinking water on growth performance, gastrointestinal pH, digestive enzymes, intestinal histomorphology, and cecum microbial counting of the broiler chicken. A total of 540 one-day-old male broilers (Arbor Acre) were randomly assigned to 5 treatments, with 6 replicates of 18 chicks per replicate. Broilers received diets and water as follows: NC (negative control, basal diet, normal water), PC (positive control, basal diet + 8 ppm colistin sulfate + 8 ppm enduracidin, normal water), A1 (basal diet, continuous supply of acidified water during whole experiment period), A2 (basal diet, intermittent acidification of water during 0 to 14 d, 22 to 28 d, and 36 to 42 d), and A3 [basal diet, intermittent acidification of water (24 h/d from 0 to 14 d and from 10:00 am to 4:00 pm on d 15 to 42)]. During the entire period, the acidified groups (A1, A2, and A3) and PC group showed improve on weight gain, average daily gain and feed conversion ratio compared to NC group (P < 0.05). The pH in crop, proventriculus and ileum at 43 d declined by 0.04, 1.03, 1.23; 0.55, 0.69, 0.70; and 0.63, 0.74, 1.21 in A1, A2, and A3 group, respectively. There was a significant decline of lipase activity in the PC and acidified groups compared to NC group. The A2 group had higher villus height in jejunum than NC group. The PC and acidified groups reduced (P < 0.05) the total aerobic bacteria count of cecum when contrasted to NC group. Therefore, we conclude that acidified drinking water can improve growth performance, compensate for gastric acidity, and control pathogenic bacteria in broilers and may be considered as a potential alternative to improve production parameters. Discontinuous supply of acidified water had the same or even better influence on broilers compared to continuous supply.

Abstract
Estimation formulas are usually used to calculate renal depth when glomerular filtration rate (GFR) is measured by the Gates method. Horseshoe kidney (HSK) anatomical structure is different from the normal form of the kidney. The existing formulas are based on the normal form. It is unknown whether the existing formulas are valid in HSK patients. This study was performed to estimate the accuracy of the existing 6 renal depth estimation formulas in HSK.Renal depth and total thickness (T, cm) of the body at the level of the kidneys were measured by CT in 94 HSK patients. Their sex, age, height (H, cm), and weight (W, kg) were recorded. The existing 6 estimation formulas were used to obtain estimated renal depth. Correlation coefficients, Bland-Altman analysis, and paired t test were performed between estimated and the CT measured renal depth.Estimated renal depths were all lower than the CT measured renal depths and there was significant difference between estimated and CT measured renal depth. The CT measured renal depth and estimated renal depth derived from Ma GY formula correlated best (right: r = 0.80, P < .01; left: r = 0.77, P < .01). The renal depth derived from Tonnesen formula was significantly lower than the CT measured renal depth. The agreement between the estimated renal depth derived from Tonnesen formula and the CT measured renal depth was the worst, with the mean difference of (right: -3.11 ± 1.13 cm; left: -2.79 ± 1.07 cm). The agreement between the estimated renal depth derived from Li Q formula and Ma GY formula and the CT measured renal depth was the best, with the mean difference of right: -1.68 ± 1.09 cm; left: -1.32 ± 1.06 cm and right: -1.59 ± 1.01 cm; left: -1.59 ± 0.99 cm, respectively. But the greatest error of the difference between Li Q formula and Ma GY formula estimated depth and the CT measured depth was up to -4.83 cm, and the estimated deviation is unacceptable.All the existing formulas do not fully apply to HSK. To provide reliable and accurate estimates of renal depth, we should develop a new formula to estimate the renal depth in HSK patients.

Abstract
Objective: To observe the effects of Ginaton on blood nitric oxide (NO) and nitric oxide synthase (NOS) in patients with delayed encephalopathy after acute carbon monoxide poisoning (DEACMP). Methods: A total of 116 patients with DEACMP who were treated in Emergency Department of Harrison International Peace Hospital Affiliated to Hebei Medical University from January 2012 to April 2016 were enrolled and ran-domly divided into control group and treatment group using a random number table, with 58 patients in each group. The patients in the control group were given conventional treatment including hyperbaric oxygen, preven-tion and treatment of cerebral edema, and promotion of brain cell metabolism, and those in the treatment group were given Ginaton in addition to the conventional treatment. The course of treatment was 2 weeks for both groups. The levels of neuron-specific enolase (NSE) , NO, NOS, and inducible nitric oxide synthase (iNOS) were measured before treatment and at 2 weeks after treatment, and the change in Mini-Mental State Examina-tion (MMSE) score and clinical outcome were observed in both groups. The correlation between the blood NO level on admission and the MMSE score was analyzed. Results: There was a significant difference in the overall response rate between the treatment group and the control group (81.03% vs 62.07%, χ(2) = 5.124, P=0.024). Be-fore treatment, there were no significant differences in the levels of NO and NSE, the activity of NOS and iN-OS, and MMSE score between the two groups (P>0.05). After treatment, both groups showed reductions in the levels of NO and NSE and the activity of NOS and iNOS, but the treatment group had significantly greater reduc-tions compared with the control group (P<0.05). Both groups showed a significant increase in the MMSE score after treatment, while the treatment group had a significantly greater increase compared with the control group (P<0.05). In the patients with DEACMP, the blood NO level on admission was negatively correlated with the MMSE score (r=-0.268, P=0.004). Conclusion: In the treatment of patients with DEACMP, Ginaton can effectively reduce the levels of NO and NSE and the activity of NOS and iNOS, increase the MMSE score, and promote the recovery of neurological function.

Abstract
Positron emission tomography/integrated computed tomography (PET/CT) provides the most accurate imaging modality for preoperative lung cancer staging. However, the diagnostic accuracy of maximum standardized uptake value (SUVmax) for mediastinal (N2) lymph nodes (LN) is unclear. We compared SUVmax, the ratio of LN to primary tumor SUVmax (SUVn/t), and SUVn/t multiplied by maximal tumor diameter (SUVindex) in terms of their abilities to predict mediastinal LN malignancy.We retrospectively analyzed 170 mediastinal LN stations from 73 consecutive patients who underwent systemic LN resection and PET/CT within 27 days. The SUVmax of the primary tumors was >2.0 and the SUVmax of the mediastinal LN stations ranged from 2.0 to 7.0 on PET/CT. Receiver-operating characteristic curves (ROCs) of SUVmax, SUVn/t, and SUVindex were calculated separately and the areas under the curves (AUCs) were used to assess the abilities of the parameters to predict LN malignancy. The optimal cutoff values were calculated from each ROC curve and the diagnostic abilities were also compared. The diagnostic accuracies of the 3 methods were also assessed separately in smoking and nonsmoking patients.Twenty-eight LN stations were malignancy-positive and the remaining 142 were malignancy-negative. The AUCs for SUVindex, SUVn/t, and SUVmax were 0.709, 0.590, and 0.673, respectively, and the optimal cutoff values for SUVindex, SUVn/t, and SUVmax were 1.11, 0.34, and 3.6, respectively. The differences between SUVindex and SUVn/t were significant, but there was no significant difference between SUVindex and SUVmax. There were no significant differences between smokers and nonsmokers in the AUCs for any of the methods for predicting LN malignancy (P values >0.05).SUVindex may be a predictor of mediastinal LN malignancy in lung cancer patients.

Abstract
Dendritic cell immunoreceptor (DCIR) is a C-type lectin receptor containing a
carbohydrate recognition domain in its extracellular portion and an immunoreceptor
tyrosine–based inhibitory motif, which transduces negative signals into cells, in its
cytoplasmic portion. Previously, we showed that Dcir–/– mice
spontaneously develop autoimmune diseases such as enthesitis and sialadenitis due to
excess expansion of dendritic cells (DCs), suggesting that DCIR is critically important
for the homeostasis of the immune system. In this report, we analyzed the role of DCIR in
the development of experimental autoimmune encephalomyelitis (EAE), an autoimmune disease
model for multiple sclerosis. We found that EAE was exacerbated in
Dcir–/– mice associated with severe demyelination of the
spinal cords. The number of infiltrated CD11c+ DCs and CD4+ T cells
into spinal cords was increased in Dcir–/– mice. Recall
proliferative response of lymph node cells was higher in
Dcir–/– mice compared with wild-type mice. These
observations suggest that DCIR is an important negative regulator of the immune system,
and Dcir–/– mice should be useful for analyzing the roles of
DCIR in an array of autoimmune diseases.

Abstract
AIM Gate's glomerular filtration rate (gGFR) measured by (99m) Tc-DTPA renal dynamic imaging and estimated GFR (eGFR) estimated by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation are two indexes used to evaluate renal function. However, little is known about whether gGFR can be used to accurately assess renal function in horseshoe kidney (HSK) patients with renal fusion anomalies. METHODS Nineteen HSK patients (HSK group) diagnosed by renal imaging and 38 CKD patients with "normal kidney shape" (non-HSK group) matched to the HSK patients in terms of gender, age and biochemical indicators at Chinese PLA General Hospital were enrolled in this study. Gender, age, serum total protein (TP), albumin (ALB), blood urea nitrogen (BUN), serum creatinine (Scr), gGFR and eGFR were recorded and analyzed using χ(2) test, t-test, and Wilcoxon test which was presented as median(IQR). RESULTS (1) There were no significant differences in gender, age, TP, ALB, BUN, Scr, or eGFR between these two groups. (2) In HSK patients, the renogram showed abnormal renal axis with the lower poles orientated medially. The timed uptake curve showed that the isotope excretion in the HSK group was slower than that in the non-HSK group. (3) For all HSK patients, gGFR was significantly lower than eGFR (range -12.52 mL/min per 1.73m(2) to -93.18 mL/min per 1.73m(2) ). There was no significant difference in eGFR between the HSK [96.42 (36.02) mL/min per 1.73 m(2) ] and non-HSK groups [94.46 (33.00) mL/min per 1.73 m(2) ]. The gGFR of the HSK group [41.18 (16.60) mL/min per 1.73m(2) ] was much lower than that of the non-HSK group [86.42(26.40) mL/min per 1.73m(2) , P < 0.001] and the eGFR of the HSK group (P < 0.001). The gGFR and eGFR of the non-HSK group were not significantly different. CONCLUSION gGFR measured by (99m) Tc-DTPA renal dynamic imaging is significantly lower than eGFR estimated by the CKD-EPI equation, which indicates that isotope renogram cannot accurately evaluate the GFR of HSK patients.

Abstract
Type 5 adenoviruses expressing mda-7 gene (Ad-mda-7) induced cell death in various kinds of human tumors, but pancreatic carcinoma cells were relatively resistant to Ad-mda-7-mediated cytotoxicity. We then examined whether infection of Ad-mda-7 together with replication-competent Ad produced combinatory cytotoxic effects. We prepared replication-competent Ad, defective of the E1B55kDa gene or activated by a transcriptional regulatory region of the midkine or the survivin gene of which the expression was up-regulated in human tumors. Type 5 Ad bearing the exogenous regulatory region were further modified by replacing the fiber-knob region with that of type 35 Ad. Pancreatic carcinoma cells were infected with replication-incompetent Ad-mda-7 and the replication-competent Ad. Combinatory effects were examined with the CalcuSyn software and cell cycle analyses. Ad-mda-7 and the replication-competent Ad achieved cytotoxicity to pancreatic carcinoma. A combinatory use of Ad-mda-7 and either Ad defective of the E1B55kDa gene or Ad activated by the regulatory region produced synergistic cytotoxic effects. Cell cycle analyses demonstrated that the combination increased sub-G1 populations. These data collectively suggest that expression of MDA-7 augments cytotoxicity of replication-competent Ad and achieves adjuvant effects on Ad-mediated cell death.

Abstract
This study evaluated the relationships among copeptin, ischemia-modified albumin (IMA), and extent of myocardial injury in patients with acute carbon monoxide poisoning (ACOP). A total of 110 patients with different degrees of ACOP were selected as the poisoning group, and 30 healthy individuals as the control group. The levels of troponin I (cTnI), IMA, and copeptin were detected. Based on the presence of complications, the patients were assigned to the complication (26 patients) or non-complication (84 patients) group. Levels of cTnI, IMA, and copeptin were compared among the control, complication, and non-complication groups. Compared with the control group, in the 2 h after admission, the IMA levels decreased and copeptin levels increased in the poisoning group; these changes were more significant in patients with severe ACOP than in those with mild ACOP, and the difference was statistically significant (P < 0.05). There were no differences in the IMA and copeptin levels between the groups 7 days after admission; the cTnI levels increased more significantly in patients with severe ACOP than in patients with mild and moderate ACOP, and the differences were statistically significant (P < 0.05). In the complication group, at 7 days after admission, the IMA levels decreased whereas the copeptin and cTnI levels were significantly higher than in the non-complication group, with a statistically significant difference (P < 0.05). IMA was negatively correlated with copeptin. IMA and copeptin detection is clinically useful in the early diagnosis and prognosis of ACOP-related myocardial injury and in guiding early clinical drug application.

Abstract
OBJECTIVE This study was performed to develop a new formula to estimate the renal depth in both children and adults; then compare the new formula with previously published formulas. METHODS Renal depth and total thickness (T, cm) of the body at the level of the kidneys were measured by CT in 113 children and 246 adults. Their sex, age, height (H, cm), and weight (W, kg) were recorded. Multiple stepwise linear regression analysis were conducted, using data from children and adults together. The 359 cases were divided into 2 random groups, of which, the first group was used to derive a regressive formula, and the second was used to verify the formula and compare the formula with previously published formulas in different groups. RESULTS Multiple stepwise linear regression analysis showed that the important variable in estimating the depth of each kidney was the ratio of body weight (W, kg) to body height (H, cm) and the total thickness (T, cm) of the body at the level of the kidneys. The new formula was as follows: for right renal depth (cm) = 0.22 × T + 7.714 × W/H-0.331 (r = 0.95), and for left renal depth (cm) = 0.238 × T + 6.553 × W/H-0.618 (r = 0.95). It is better than the other four formulas in different groups, especially in children and W/H ≤ 0.30 (in adults) groups. CONCLUSIONS We first introduced T into renal depth estimation formula and established the new formula. It has a better performance than the other four formulas in different groups. The new formula provided reliable and accurate renal depth and may contribute to improving the methods used to estimate renal function from radionuclide renography.
