Abstract
AIM This study aimed to reveal the unique microenvironment of peri-implantitis through single-cell analysis. MATERIALS AND METHODS Herein, we performed single-cell RNA sequencing (scRNA-seq) of biopsies from patients with peri-implantitis (PI) and compared the results with healthy individuals (H) and patients with periodontitis (PD). RESULTS Decreased numbers of stromal cells and increased immune cells were found in the PI group, which implies a severe inflammatory infiltration. The fibroblasts were found to be heterogeneous and the specific pro-inflammatory CXCL13+ sub-cluster was more represented in the PI group, in contrast to the PD and H groups. Furthermore, more neutrophil infiltration was detected in the PI group than in the PD group, and cell-cell communication and ligand-receptor pairs revealed most neutrophils were recruited by CXCL13+ fibroblasts through CXCL8/CXCL6-CXCR2/CXCR1. Notably, our study demonstrated that the unique microenvironment of the PI group promoted the differentiation of monocyte/macrophage lineage cells into osteoclasts, which might explain the faster and more severe bone resorption in the progression of PI than PD. CONCLUSIONS Collectively, this study suggests a unique immune microenvironment of PI, which may explain the differences between PI and PD in the clinic. These outcomes will aid in finding new specific and effective treatments for PI.

Abstract
Objective: To investigate the role of neutrophil extracellular traps (NETs) in immune checkpoint inhibitor-associated myocarditis (ICIAM) with programmed death protein-1 (PD-1) inhibitors involvement, and to explore the therapeutic potential of targeting NETs in the treatment of ICIAM. Methods: Thirty 6-week-old male BALB/c mice were randomly divided into control group (n=10), myocarditis group (n=10), and treatment group (n=10). Apart from the control group, each mouse was subcutaneously injected with 100 μl of complete Freund's adjuvant containing 250 μg of mouse cardiac troponin I peptide on the 1st and 7th day. Starting on the 8th day, PD-1 inhibitor (15 μg/per mouse) was intraperitoneally injected every other day for a total of 5 times. Since 1 day before the beginning of PD-1+TnI injection, the treatment group was injected with PF-1355 (50 mg·kg-1·d-1) for 16 consecutive days. The mice's general state was observed during the whole process. Real-time fluorescence quantitative PCR (RTFQ-PCR) was carried out to evaluate the transcriptional regulation of neutrophil related chemokines, NETs, pyronecrosis related factors and proinflammatory cytokines. Immunohistochemistry, immunofluorescence and western blot were applied to determine the changes of pyrosis related molecules. Echocardiography showed the differences of main cardiac indexes while cardiac pathology compared the degree of inflammatory infiltration in 3 gruops. Results: The immunofluorescence intensity of myocardial NETs in the myocarditis group was significantly increased compared to the control group mice (2.49±0.08 and 0.99±0.26, P<0.001). The protein expression levels of pyroptosis-related NLRP3, cleaved-Caspase 1, Caspase 1, cleaved-GSDMD, GSDMD, IL-1β and IL-18 in myocardial tissue of the model group were higher than those of the control group (all P<0.05). After treatment with PF-1355, compared to the myocarditis group, the left ventricular ejection fraction (LVEF) (73.58%±5.31% and 58.12%±3.19%, P<0.001) and left ventricular fraction shortening (LVFS) (39.78%±4.31% and 33.89%±2.19%, P<0.001) increased. H-E staining showed a reduction in inflammatory infiltration area in the treatment group compared to the myocarditis group (30.12%±3.57% and 14.92%±2.46%, P<0.001). The immunofluorescence intensity of NETs decreased in the treatment group compared to the myocarditis group (2.52±0.04 and 1.03±0.05, P<0.001). The levels of NLRP3 and other pyroptosis-related molecules were downregulated in the treatment group compared to the myocarditis group (all P<0.05). Conclusions: NETs lead to myocardial cell pyroptosis by activating the NLRP3 inflammasome in PD-1 inhibitor-associated myocarditis. The specific MPO inhibitor PF-1355 shows a therapeutic potential by regulating the formation of NETs, decreasing NLRP3 level and relieving myocardial pyroptosis, thus reducing myocardial damage.

Abstract
Objective: To analyze the efficacy and safety of the sodium channel blockers (SCB) antiseizure medication in the treatment of focal epilepsy in infants under 6 months of age. Methods: This was a case series study. Infants with focal epilepsy with onset within 6 months of age and treated with SCB attending the Department of Neurology of Beijing Children's Hospital from June 2016 to April 2022 were collected. The clinical data, auxiliary examinations, SCB application, efficacy, adverse reactions, and prognosis were analyzed retrospectively. Patients were grouped according to type of seizure and epileptic syndrome, age of onset and etiology. Chi square test and Fisher exact test were used to analyze the differences between groups statistically. Results: A total of 118 infants were enrolled, 65 males and 53 females, with an age of epilepsy onset of 56 (4, 114) days. Developmental and epileptic encephalopathy was diagnosed in 60 infants, 39 had self-limited neonatal and (or) infantile epilepsy, and 19 had non-syndromic focal epilepsy. Application of SCB: 106 used oxcarbazepine, 2 used lacosamide, 9 switched from oxcarbazepine to lacosamide or a combination of 2 SCB, and 1 used oxcarbazepine, lacosamide, and lamotrigine successively; oxcarbazepine was the first choice in 46 cases. The age at which SCB was applied was 103 (53, 144) days. The children were followed up for 6 months to 6 years. SCB was effective in 89 cases (75.4%), including 70 cases (59.3%) who achieved seizure freedom. The seizure-free rate was higher in the focal epilepsy only group than in the group with other seizure types (64.4% (65/101) vs. 4/17, χ²=9.99, P<0.05). The responder and seizure-free rates were all higher in the group with the onset age of >3-6 months than the group >1-3 months (84.4% (38/45) vs. 62.5% (20/32), 73.3% (33/45) vs. 46.9% (15/32), χ²=4.85 and 5.58, both P<0.05). With the exception of variants in the PRRT2 gene, those with variants in sodium or potassium channels had higher responder and seizure-free rates than those with variants in other genes(86.2% (25/29) vs. 45.5% (10/22), 62.1% (18/29) vs. 22.7% (5/22), χ²=9.65 and 7.82,both P<0.05). The most common adverse event was transient hyponatremia, which happened in 66 cases (55.9%). There were 9 cases of rash, which subsided in 6 cases after discontinuing oxcarbazepine and switching to lacosamide, and 7 cases of electrocardiogram abnormalities, which improved after withdrawing oxcarbazepine and changing to lacosamide in 1 case. Conclusion: SCB are effective and tolerable in the treatment of focal epilepsy in infants under 6 months of age, with better efficacy in patients with genetic variants of the sodium or potassium channel, focal seizures only, and seizure onset >3-6 months of age.

Abstract
Objective: To analyze the value of 3-dimensional speckle tracking echocardiograghy (3D-STE) derived strain parameters on the detection of subclinical myocardial deformation alterations in patients with lymphoma treated with anthracycline agents. Methods: This study was a retrospective study. A total of 37 patients with newly diagnosed diffuse large B cell non-Hodgkin lymphoma between December 2012 and December 2014 in Cancer Center, Fudan university were included. 3D-STE strain measurements were performed at baseline (T0),after the completion of two therapy circles (T1) and at the end of anthracycline regimen chemotherapy (Te). Echocardiography images were analyzed on the TTA workstation, and the indexes included left atrial minimum volume (LAVmin), left atrial emptying index (LAEF), left atrial active emptying index (LAAEF), as well as the left ventricular global longitudinal strain (LVGLS), left ventricular global circumferential strain (LVGCS), left atrial global longitudinal strain (LAGLS). The overall left atrioventricular longitudinal strain (LAVGLS) was calculated, which was the sum of the absolute values of LVGLS and LAGLS. The changes of left ventricular strain indexes measured by 3D-STE at different time points of patients were evaluated. Results: Thirty-seven patients with DLBCL, aged (48.3±12.1)years, including 23 males (63.9%), were enrolled. Compared with baseline, LVGLS (T1: (-18.63±4.73)% vs. (-22.13±4.40)%, P=0.001; Te:(-18.26±4.64)% vs. (-22.13±4.40)%, P<0.001), LAGLS (T1: (20.41±5.56)% vs. (23.98±5.59)%, P=0.003; Te: (17.60±3.96)% vs. (23.98±5.59)%, P<0.001) and LAVGLS (T1: (39.05±7.60)% vs. (46.11±7.77)%, P<0.001; Te: (40.34±8.55)% vs. (46.11±7.77)%, P<0.001) were all deteriorated at the T1 and Te. While LVGCS ((-21.98±5.82)% vs. (-26.15±7.51)%, P=0.010), LAVmin ((23.93±7.29)ml vs. (20.33±7.03)ml, P=0.029), LAEF ((28.94±11.16)% vs. (35.79±11.12)%, P=0.002) and LAAEF ((11.93±10.00)% vs. (18.10±9.96)%, P=0.013) were decreased only until Te. Conclusions: 3D-STE strain measurements could detect early myocaridial function alteration in patients receiving anthracycline regimen chemotherapy, thus may provide a novel approach to monitor anthracycline caused myocardial toxicity.

Abstract
Objective: To investigate the efficacy and safety of liver venous deprivation (LVD) before secondary resection of primary liver cancer. Methods: 56 patients with advanced primary liver cancer who were not suitable for primary resection in Liver Surgery Department of Xinxiang Central Hospital from January 2018 to January 2019 were analyzed retrospectively. They were divided into liver vein deprivation group (LVD group: LVD+ PVE, n=26) and portal vein embolization group (PVE group, n=30). The dynamic changes of liver reserve function and future liver remnant volume (FLR-V), R0 resection rate, surgical complications, postoperative recurrence rate and overall survival rate of two groups before and after LVD/PVE were compared. Results: The success rate of puncture and embolization in LVD group and PVE group was 100%. There were no grade Ⅳ complications, and there was no significant difference of grades Ⅰ, Ⅱ and Ⅲ complications between the groups (P=0.808). The FLR-V of LVD group before embolization, 7, 14 and 21 days after embolization was (493.1±25.8), (673.2±56.1), (779.5±81.6) and (853.3±85.2) cm(3), respectively. The FLR-V of PVE group before embolization, 7, 14 and 21 days after embolization were (502.4±20.1), (688.6±43.9), (656.8±73.7) and (563.5±69.1) cm(3), respectively. There was no significant difference in FLR-V between the two groups before and 7 days after embolization (P>0.05). The FLR-V of LVD group was higher than that of PVE group at 14 and 21 days after embolization (P<0.01). The preparation time of LVD group was (20.4±6.3) days, which was shorter than that of PVE group [(31.5±8.8) days, P=0.045]. The rate of secondary hepatectomy was 92.3% (24/26), which was higher than that of PVE group [70.0% (21/30), P=0.036]. The R0 resection rate was 87.5% (21/24), which was higher than that of the PVE group [57.1% (12/21), P=0.022]. However, there were no significant differences in surgical methods, operation time, intraoperative blood loss, Clavien-Dindo complication grade and length of hospital stay between the two groups (P>0.05). After hepatectomy, the median recurrence time and median survival time of LVD group were 12.6 months and 21.3 months, respectively, which were longer than those of PVE group (9.4 months and 13.5 months, respectively, P<0.01). Conclusions: For patients with advanced liver cancer who are not suitable for primary hepatectomy, preoperative LVD can significantly increase FLR-V, improve the resection rate of secondary surgery, shorten the preparation time of two operations, and do not increase surgical complications. Moreover, patients with LVD can improve the R0 resection rate of secondary surgery. The postoperative recurrence time and overall survival rate of patients with LVD are better than those of patients with PVE, and LVD has a good long-term effect.

Abstract
Abstract
Objectives Due to its high morbidity, high mortality, and high disability, stroke has been the first cause of death and the major cause of adult disability in China. Natural borneol has been widely utilized in Traditional Chinese Medicine to promote drug absorption. Formononetin is a natural isoflavonoid with potent neuroprotective activity but poor brain delivery.
Methods This study aimed to screen the optimum proportion that natural borneol promotes formononetin entry into the brain, evaluate the anti-cerebral ischaemia efficacy of formononetin/natural borneol combination in middle cerebral artery occlusion/reperfusion model rats, and clarify the possible mechanism for natural borneol’s promoting formononetin delivery in the brain.
Key findings Our studies exhibited that natural borneol remarkably promoted formononetin entry into the brain when combined with formononetin in a 1 : 1 molar ratio and notably improved neuro-behavioural scores and reduced the infarct of middle cerebral artery occlusion/reperfusion model rats. This study further discovered that the enhanced anti-cerebral ischaemia effect resulted from natural borneol increasing the permeability of the blood-brain barrier to elevate formononetin concentration in the brain rather than the pharmacodynamic synergy or addition between formononetin and natural borneol.
Conclusions The study provides a good strategy to screen drug combinations for the treatment of brain disease by combining natural borneol with other drugs.

Abstract
Ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS) was used to investigate the metabolites of maackiain in rats based on the prediction function of UNIFI data processing system and liver microsomal incubation in vitro. Ten metabolites of maackiain after oral absorption were reasonably deduced and characterized. It was found that the biotransformation of maackiain mainly included phase Ⅰ oxidation, dehydrogenation, phase Ⅱ sulfate conjugation, glucosylation conjugation, and glucuronic acid conjugation. Among them, the product of glucosylation conjugation, trifolirhizin, was identified by comparison with the reference for the first time. Liver microsomal incubation in vitro further confirmed the metabolites and metabolic pathways of maackiain in rats. The metabolites in the blood, urine, and feces complemented each other, which revealed the migration, metabolism, and excretion modes of maackiain in rats. This study lays a foundation for the further investigation of the metabolic mechanism of maackiain in vivo and the in-depth research on the mechanism of pharmacodynamics and toxicity.

Abstract
Ingenol, as the precursor of the marketed drug ingenol mebutate, has been proven to have a variety of bioactivities. The purpose of this study was to identify the metabolites of ingenol using ultra-performance liquid chromatography-quadrupole time-of-flight-mass spectrometry (UPLC-Q/TOF-MS) combined with UNIFI software. Plasma, urine and fecal samples of rats were obtained and analyzed. A total of 18 metabolites were detected and identified in rat, including five phase II metabolites (M14-M18). Moreover, as microbial biotransformation is helpful to obtain sufficient reference standards of metabolites, the co-culture of ingenol with the fungus Cunninghamella elegans bio-110930 was also studied and yielded 4 phase I metabolites, in which reference standards of three metabolites were further obtained by preparative scale biotransformation. By matching their retention times, accurate masses, and fragment ions with metabolites in rat, the structures of three metabolites (M2, M3 and M4) were unambiguously confirmed by NMR technology. The results revealed that C. elegans bio-110930 functioned as an appropriate model to mimic and prepare phase I metabolism of ingenol in vivo to a certain extent. It also revealed that hydroxylation, oxygenation, sulfonation, and glucuronidation were the major metabolic pathways of ingenol. Furthermore, the first systematic metabolic study of ingenol is of great significance to elucidate the metabolites and metabolic pathways in vivo, which is helpful to predict metabolites of ingenol in humans, understand the elimination mechanism of ingenol, and clarify its effectiveness and toxicity.

Abstract
Objective: To evalute the accuracy and clinical outcome of a real-time navigation system for the placement of quad zygomatic implants. Methods: Twenty-four patients [9 males and 15 females, mean age was (50.8±14.7) years old], from January 2015 to December 2019, with 96 zygomatic implants placed under a real-time navigation system in Department of Second Dental Center and Department of Oral Implantology of Ninth People's Hospital, Shanghai Jiaotong University School of Medicine were included in the study. The preoperative and the postoperative multislice CT or cone-beam CT were fused to measure and record the entry, exit and angle deviation between the planned and placed implants. The implants were divided into groups according to implant insertion approach (real-time navigation and free-hand), implant length (<47.5 mm and ≥47.5 mm) and implant position (proximal and distal implant). And the differences of implant accuracy were analyzed. The intraoperative and postoperative complications were also recorded. The implant survival rate was evaluated after 6 months follow-up. A P value<0.05 indicates statistical significance. Results: The mean entry, exit and angle deviation of zygomatic implants were (1.49±0.64) mm, [2.03(1.58, 2.40)] mm and (2.49°±1.12°), respectively. The average entry, exit and angle deviation of the navigation guided implant insertion group were (1.45±0.60) mm, (1.96±0.44) mm and (2.66±1.13°) respectively, while those of the free-hand group were (1.50±0.64) mm, (2.04±0.79) mm and (2.50°±1.13°) respectively. There was no significant difference between the two groups (P>0.05). The average entry, exit and angle deviation of the group with length<47.5 mm were (1.42±0.60) mm, (2.13±0.60) mm and (2.61°±1.08°) respectively and those of the group with length ≥ 47.5 mm were (1.52±0.65) mm, (1.98±0.82) mm and (2.43°±1.14°) respectively. No significant difference was found between the two groups (P>0.05). In proximal implant group, the average entry, exit and angle deviation were (1.55±0.69) mm, (2.05±0.92) mm and (2.48°±1.16 °) respectively while those of distal implant group were (1.43±0.57) mm, (2.01±0.57) mm and (2.49°±1.10°), respectively. No significant difference was detected between the two groups (P>0.05). All zygomatic implants were placed uneventfully. There were no intra-operative complications, and post-operative reversible complications developed in 3 patients. Two zygomatic implants were lost and the overall zygomatic implant survival rate was 97.9% (94/96) within a follow-up of 6 months. Conclusions: Quad zygomatic implant placement can be achieved with high accuracy and predictable clinical outcome under guidance of a real-time navigation system.

Abstract
Objective: To investigate the value of two-dimensional shear wave elastography (2D SWE) combined with clinical biochemical data in predicting posthepatoectomy liver failure (PHLF) in patients with hepatocellular carcinoma (HCC). Methods: A total of 274 HCC patients who underwent hepatectomy in Zhongshan Hospital Fudan University from January 2015 to January 2016 were retrospectively collected, including 235 males and 39 females, age 19-80 (56±11) years. All patients were confirmed to be HCC by postoperative pathology. The preoperative 2D SWE examination, laboratory examination results and intraoperative indicators were analyzed. According to the occurrence of PHLF after surgery, single factor analysis and multiple logistic regression analysis were performed on the above indicators to obtain a binary logistic regression model, and evaluate the diagnostic effect of the model on PHLF. In addition, 103 HCC patients from October 2019 to January 2020 were retrospectively collected as an external validation set, including 89 males and 14 females, age 23-80 (55±11) years old. Results: The liver stiffness measurement (LSM) obtained from 2D SWE, INR and Laminin (LN) were independent predictors of PHLF. The formula of prediction model PM=-15.451+0.095×LSM+11.7×INR+0.012×LN was obtained by combining above three factors. The area under the curve (AUC) of PHLF was 0.82, which was higher than that of end-stage liver disease model (MELD) score and Child-Pugh grading diagnosis of PHLF. The AUC of PHLF predicted by PM in the external validation group was 0.81. Conclusion: 2D SWE is helpful for clinicians to evaluate liver reserve function preoperatively and to predict the occurrence of PHLF in patients with HCC.

Abstract
Abstract
Objectives
To screen the cytotoxic activity of six secondary metabolites isolated from soil fungus Aspergillus niger. Importantly, to investigate the mechanism that pyoluteorin induced human triple-negative breast cancer MDA-MB-231 cells apoptosis in vitro.
Methods
The cell viability assay was tested with CTG assay. Cell cycle, apoptosis and intracellular reactive oxygen species (ROS) production assay were tested with flow cytometry. Additionally, intracellular ROS production assay and mitochondrial membrane potential assay were determined with laser scanning confocal microscopy. The expression of apoptosis-related proteins was determined with Western blot.
Key findings
Pyoluteorin displayed significantly selective cytotoxicity against human triple-negative breast cancer MDA-MB-231 cells (IC50 = 0.97 µm) with low toxicity against human breast epithelial cell MCF-10A. It was found that pyoluteorin could arrest MDA-MB-231 cells cycle at G2/M phase and induce cell apoptosis. Further experiments demonstrated that the apoptosis-inducing effect of pyoluteorin was related to reduction of mitochondrial membrane potential, accumulation of ROS and change of apoptosis-related protein expressions.
Conclusion
Our studies revealed that pyoluteorin had potent proliferation inhibition against MDA-MB-231 cells through arresting cell cycle at G2/M phase and inducing caspase-3-dependent apoptosis by mitochondrial pathway, implying that pyoluteorin may be a potential lead compound for drug discovery of human triple-negative breast cancer.

Abstract
Biosorption of radionuclides by microorganisms is a promising and effective method for the remediation of contaminated areas. pH is the most important factor during uranium biosorption by Saccharomyces cerevisiae because the pH value not only affects the biosorption rate but also affects the precipitation structure. This study investigated the effect of pH on uranium (VI) biosorption and biomineralization by S. cerevisiae. Cells have the ability to buffer the solution to neutral, allowing the biosorption system to reach an optimal level regardless of the initial pH value. This occurs because there is a release of phosphate and ammonium ions during the interaction between cells and uranium. The uranyl and phosphate ions formed nano-particles, which is chernikovite H2(UO2)2(PO4)2·8H2O (PDF #08-0296), on cell surface under the initial acidic conditions. However, under the initial alkaline conditions, the uranyl, phosphate and ammonium ions formed a large amount of scale-like precipitation, which is uramphite (NH4)(UO2)PO4·3H2O (PDF #42-0384), evenly over on cell surface.

Abstract
Objective: To study the efficacy and safety of linezolid for the treatment of patients with bacteremia caused by methicillin-resistant Staphylococcus aureus (MRSA). Methods: Totally 52 cases of MRSA bacteremia patients, from January 2010 to April 2014 in the First Affiliated Hospital, School of Medicine, Zhejiang University, were retrospectively analyzed. They were classified into two groups based on linezolid therapeutic regimen: primary treatment with linezolid (19 cases) and alternated to linezolid (33 cases). The following data were collected and compared: clinical characteristics, lasting time of fever, bacterial clearance rate, clinical efficacy, fatality rate, and adverse events. Results: Forty three of the 52 patients (82.7%) suffered complicated MRSA bacteremia. The most common clinical feature was fever[86.5%(45/52)]. Linezolid was initiatively used mostly because of renal insufficiency[68.4%(13/19)]. In the other 33 patient, glycopeptides were initiatively used, then alternated to linezolid because of persistent fever[69.7%(23/33)]; damage of kidney function during treatment period of glycopeptides[12.1%(4/33)]; occurrence of new infectious site related to MRSA[18.2%(6/33)]. The clinical efficacy were 78.9%(15/19) in the group of primary treatment with linezolid and 81.8% (27/33) in the group of alternated to linezolid, persistent time of fever were 4(3, 15) d and 12(5, 24) d, mortality during 28 d period were 15.8% (3/19) and 9.1% (3/33), adverse rate were 15.8% (3/19) and 12.1% (4/33) in these two groups, respectively (all P>0.05). Conclusion: Linezolid is an option with high clinical efficacy and good safety for MRSA bacteremia patients.

Abstract
BACKGROUND Nonalcoholic fatty liver disease (NAFLD) is a common result of obesity and metabolic syndrome. Hepatocyte injury and metabolic disorders are hallmarks of NAFLD. Stimulator of interferon genes (STING) and its downstream factor interferon regulatory factor 3 (IRF3) trigger inflammatory reaction in response to the presence of cytosolic DNA. STING has recently been shown to play an important role in early alcoholic liver disease. However, little is known about the role of STING-IRF3 pathway in hepatocyte injury. Here, we aimed to examine the effect of STING-IRF3 pathway on hepatocyte metabolism, inflammation and apoptosis. METHODS We examined the activation of the STING-IRF3 pathway, a high-fat diet (HFD)-induced obese mouse model, and determined the role of this pathway in a free fatty acid (FFA)-induced hepatocyte inflammatory response, injury, and dysfunction in L-O2 human liver cells. RESULTS STING and IRF3 were upregulated in livers of HFD-fed mice and in FFA-induced L-O2 cells. Knocking down either STING or IRF3 led to a significant reduction in FFA-induced hepatic inflammation and apoptosis, as evidenced by modulation of the nuclear factor κB (NF-κB) signaling pathway, inflammatory cytokines, and apoptotic signaling. Additionally, STING/IRF3 knockdown enhanced glycogen storage and alleviated lipid accumulation, which were found to be associated with increased expression of hepatic enzymes in glycolysis and lipid catabolism, and attenuated expression of hepatic enzymes in gluconeogenesis and lipid synthesis. CONCLUSIONS Our results suggest that the STING-IRF3 pathway promotes hepatocyte injury and dysfunction by inducing inflammation and apoptosis and by disturbing glucose and lipid metabolism. This pathway may be a novel therapeutic target for preventing NAFLD development and progression.

Abstract
Six previously undescribed C17-guaianolides, a previously undescribed guaianolide alkaloid, and two previously undescribed guaianolides as well as 10 known guaianolides were obtained from an ethanol extract of Ainsliaea yunnanensis Franch. The chemical structures of all previously reported sesquiterpenoids were determined by extensive NMR spectroscopic analysis in combination with a modified Mosher's method. All isolates were in vitro screened for inhibitory effect against nitric oxide release in RAW 264.7 macrophages stimulated by LPS. Zaluzanin C remarkably inhibited the production of nitric oxide with an IC50 value of 6.54 μM.

Abstract
Two new abietane diterpenoids (1-2) and 13 known compounds (3-15) were characterized from the branches and leaves of Abies faxoniana. The chemical structures of the new diterpenoids (1-2) were determined through the analysis of various 1D/2D NMR techniques. Compound 3 is 151,617-trinor-abietane diterpenoid conjugated with a three-membered epoxide ring. The isolated diterpenoids were tested for their cytotoxicities. Among them, compound 3 exhibited the strongest antiproliferative effect against human hepatoma cell SMMC7721 with an IC50 value of 12.5 μM. To elucidate the preliminary mechanism responsible for compound 3-induced inhibition of cell proliferation, we investigated the effects of compound 3 on apoptosis, cell cycle progression, and reactive oxygen species generation in SMMC7721 cells. The results showed that compound 3 induced cell apoptosis and excessive ROS production, but did not change the cell cycle distribution in SMMC7721 cells.

Abstract
Objective: To explore the value of dual contrast-enhanced ultrasound in preoperative T staging of rectal carcinoma. Methods: Dual contrast-enhanced ultrasound examinations were performed on 72 patients with rectal carcinoma via transrectal infusion and intravenous injection. The accordance of preoperative dual contrast-enhanced ultrasound results and postoperative pathologic results was evaluated retrospectively. Results: The overall accordance rate of preoperative T staging was 73.6% (53/72). And accordance rate was 100.0% (3/3), 100.0% (5/5), 68.4% (13/19), 71.4% (25/35)and 70.0% (7/10) for Tis , T1, T2, T3 and T4, respectively. The consistency was good (κ=0.607, χ(2) =8.363, P<0.01). The accordance rate of middle/lower vs high rectal carcinoma was 68.7% and 85.7%. Conclusion: Dual contrast-enhanced ultrasound can provide reference for preoperative T staging for patients with rectal carcinoma.

Abstract
Vlasouliolides A-D (1–4), four rare sesquiterpene lactone dimers, were isolated from Vladimiria souliei. The common structural characteristic of 1–4 is the C32 skeleton comprising two sesquiterpene lactone units linked by a C11-C13′ single bond with one acetyl connected to the C-13 position of one of the two sesquiterpene lactone units. The stereochemistries of 1–4 were assigned by a combination of NOESY correlations and Cu-Κα X-ray crystallographic analyses. Compounds 1–4 strongly inhibited the production of NO in LPS-stimulated RAW 264.7 cells. Furthermore, 1 and 2 inhibited the activation of NF-κB in LPS-induced 293T cells.

Abstract
BACKGROUNDS Inula helenium L. is an herb with anti-inflammatory properties. Sesquiterpene lactones (SLs), mainly alantolactone (AL) and isoalantolactone (IAL), are considered as its active ingredients. However, the anti-inflammatory effects of SL-containing extracts of I. helenium have not been explored. Here we prepared total SLs from I. helenium (TSL-IHL), analyzed its chemical constituents, and performed cellular and animal studies to evaluate its anti-inflammatory activities. MATERIALS AND METHODS The chemical profile of TSL-IHL was analyzed by HPLC-UV. Its in vitro effects on the activation of signaling pathways and expression of inflammatory genes were examined by western blotting and quantitative real-time PCR, respectively, and compared with those of AL and IAL. Its in vivo anti-inflammatory effects were evaluated in adjuvant- and collagen-induced arthritis rat models. RESULTS Chemical analysis showed that AL and IAL represent major constituents of TSL-IHL. TSL-IHL, as well as AL and IAL, could inhibit TNF-α-induced activation of NF-κB and MAPK pathways in b. End3 cells, suppress the expressions of MMP-3, MCP-1, and IL-1 in TNF-α-stimulated synovial fibroblasts, and IL-1, IL-6, and iNOS in LPS-activated RAW 264.7 cells in a dose-dependent manner in the range of 0.6-2.4μg/mL. Oral administration of TSL-IHL at 12.5-50mg/kg could dose-dependently alleviate the arthritic severity and paw swelling in either developing or developed phases of arthritis of rats induced by adjuvant or collagen CONCLUSIONS: These results indicated potentials of TSL-IHL in prevention and therapy of rheumatoid arthritis.

Abstract
Intestinal epithelial stem cells are highly sensitive to differentiation induced by endoplasmic reticulum (ER) stress. Colorectal cancer develops from mutated intestinal epithelial stem cells. The most frequent initiating mutation occurs in Apc, which results in hyperactivated Wnt signalling. This causes hyperproliferation and reduced sensitivity to chemotherapy, but whether these mutated stem cells are sensitive to ER stress induced differentiation remains unknown. Here we examined this by generating mice in which both Apc and ER stress repressor chaperone Grp78 can be conditionally deleted from the intestinal epithelium. For molecular studies, we used intestinal organoids derived from these mice. Homozygous loss of Apc alone resulted in crypt elongation, activation of the Wnt signature and accumulation of intestinal epithelial stem cells, as expected. This phenotype was however completely rescued on activation of ER stress by additional deletion of Grp78. In these Apc-Grp78 double mutant animals, stem cells were rapidly lost and repopulation occurred by non-mutant cells that had escaped recombination, suggesting that Apc-Grp78 double mutant stem cells had lost self-renewal capacity. Although in Apc-Grp78 double mutant mice the Wnt signature was lost, these intestines exhibited ubiquitous epithelial presence of nuclear β-catenin. This suggests that ER stress interferes with Wnt signalling downstream of nuclear β-catenin. In conclusion, our findings indicate that ER stress signalling results in loss of Apc mutated intestinal epithelial stem cells by interference with the Wnt signature. In contrast to many known inhibitors of Wnt signalling, ER stress acts downstream of β-catenin. Therefore, ER stress poses a promising target in colorectal cancers, which develop as a result of Wnt activating mutations.

Abstract
Esophageal submucosal gland duct adenoma (ESGDA) is a rare tumor. The clinicopathological features of the ESGDA and its precursor lesion have not been comprehensively evaluated. In this study, we aimed at delineating the clinicopathological features of the ESGDA and cyst formation of the esophageal submucosal gland duct (ESGD), as well as their correlations and clinical implications. We identified three cases of ESGDA and 16 cases of cyst formation of the ESGD among 786 endoscopic mucosal resection specimens over a 7-year period. The median patient age was 58 years with a male predominance. These lesions were small submucosal bulges locating at the lower esophagus with a size no more than 1 cm. The main microscopic changes of these lesions included content retention, multilayered epithelium or papillary folds of the ESGD and inflammatory cell infiltration, acidophilic degeneration, hyperplasia or atrophy of the acini. The included cases generally showed moderate to severe microscopic esophagitis. The ESGDA was mainly consisted by multiple glandular cysts covered by two layers of cells. Immunohistochemical results showed that the luminal duct lining cells and basal cells were positive for CK7 and p63, respectively. Both of the two layer cells were positive for HMWCK and negative for CK20, p53, CDX2, MUC5AC, MUC6, MUC2 and MUC1. The proliferation index was very low (1%). The diagnostic criteria of the ESGDA were proposed and, the differential diagnosis was discussed. Cyst formation of the ESGD is considered to be the precursor lesion of the ESGDA, because they have overlapping clinicopathological features with progressive relationship. In addition, the ESGDA have close connection with advance of the GERD and, probably, an increased risk of carcinoma.

Abstract
Investigation of the ethanol extract of the whole plant of Ainsliaea yunnanensis led to the isolation of four new dimeric sesquiterpene lactones, ainsliadimer F-I (1-4), together with seven known dimeric sesquiterpene lactones (5-11) and ten sesquiterpenes (12-21). Their structures were elucidated by spectroscopic methods. The relative stereochemistry of ainsliadimer F was further confirmed by single crystal X-ray diffraction analysis. Compounds 1-21 were tested for the inhibition of nuclear factor kappa B (NF-κB) in the 293-NF-κB-luciferase reporter cell line induced by lipopolysaccharide (LPS), and Compounds 5, 18, 20 and 21 were further tested for the production of TNF-α, IL-1β, IL-6 and IL-10 in RAW 264.7 macrophages induced by LPS. Compounds 5, 18, 20 and 21 exhibited significant activity in anti-inflammatory activity assays.

Abstract
Phytochemical investigation of Abies faxoniana Rehd. led to the isolation of two pairs of new epimeric spirolactone-type triterpenoids (1/1' and 2/2') and 11 known terpenoids (3-13). Compounds 1/1' and 2/2' were isolated as epimeric mixtures due to the C-23 ketal tautomerism in their spirolactone structures. The dynamic HPLC manifested that the C-23 epimeric mixtures interconverted into each other in solution. Structure determinations were based on extensive NMR and HRESIMS spectroscopic analysis. Meanwhile, their cytotoxic activities were tested by MTT method. Compound 5 showed cytotoxicities against MCF-7 and A549 cells with IC50 values of 6.5 and 5.7μM, respectively. Compounds 1/1' had IC50 values of 10.0 and 12.3μM for Huh7 and SMMC7721 cells, respectively.

Abstract
Eighteen terpenoids (1-18) were isolated from Illicium merrillianum. Compound 1 was identified as new compound, and its structure was established by comprehensive spectroscopic analysis and single-crystal X-ray diffraction. All compounds were evaluated for nerve growth factor (NGF)-mediated neurite outgrowth activity using rat pheochromocytoma (PC12) cells as a model system of neuronal differentiation. Compounds 1, 3, 18 showed significant neurite outgrowth-promoting activity in the presence of 20 ng/ml NGF in a dose-dependent manner at concentrations of 1-100 μM after 24-h treatment. Subtle difference of functional groups at C-2 position in hopane-type triterpene resulted in enormous bioactivity difference, compound 1 was neurotrophic but 2 was cytotoxic.

Abstract
Valepotriates, plant secondary metabolites of the family Valerianaceae, contain various acyloxy group linkages to the valepotriate nucleus and exhibit significant biological activities. Identification of valepotriates is important to uncover potential lead compounds for the development of new sedative and antitumor drugs. However, making their structure elucidation by nuclear magnetic resonance (NMR) experiments is too difficult to be realized because of the overlapped carbonyl carbon signals of acyloxy groups substituted at different positions. Thus, the mass spectrometric profiling of these compounds in positive ion mode was developed to unveil the exact linkage of acyloxy group and the core of valepotriate. In this study, electrospray ionization tandem multistage mass spectrometry (ESI-MS/MS(n)) in ion trap and collision-induced dissociation tandem MS were used to investigate the fragmentation pathways of four types of valepotriates in Valeriana jatamansi, including 5-hydroxy-5,6-dihydrovaltrate hydrin (5-hydroxy-5,6-dihydrovaltrate chlorohydrin), 5,6-dihydrovaltrate hydrin (5,6-dihydrovaltrate chlorohydrin), 5-hydroxy-5,6-dihydrovaltrate and valtrate hydrin (valtrate chlorohydrin). The high-resolution mass spectrum (HRMS) data of all the investigated valepotriates from quadrupole time-of-flight MS/MS were used as a supportive of the fragmentation rules we hypothesized from ion-trap stepwise MS(n). As a result, the loss sequence of acyloxy groups and the abundance of key product ions, in combination with the characteristic product ions corresponding to the valepotriate nucleus, could readily differentiate the four different types of valepotriates. The summarized fragmentation rules were also successfully exploited for the structural characterization of three new trace valepotriates from V. jatamansi. The results indicated that the developed analytical method could be employed as a rapid, effective technique for structural characterization of valepotriates, especially for the trace compounds that could not be identified by NMR techniques. This study may also arouse interest for further structural analysis of other valepotriate-containing type herbal medicines.

Abstract
OBJECTIVE The objective was to study the clinicopathologic features, grading, treatment protocols, and prognostic of gastroenteropancreatic neuroendocrine tumor (NET) with liver metastasis and primary hepatic NET. MATERIALS AND METHODS The clinical data of 34 patients with hepatic NET were retrospectively reviewed. According to the primary tumor location and 2010 World Health Organization classification, the cases were categorized to analyze the clinicopathologic features, treatment condition, and prognostic factors. RESULTS There was a marked male predominance either in gastroenteropancreatic NET liver metastasis group or primary group. Primary hepatic NET is mostly single nodule located in the right lobe of liver, and the metastatic hepatic NET is mostly from pancreas with multiple nodules and metastasizes to both lobes of the liver, with a high degree of malignancy and poor prognosis. There are 17 cases (50%) of NET and 17 cases (50%) of neuroendocrine carcinoma (NEC) in all the 34 patients of this study. The mitotic figure and Ki-67 proliferation index are both higher in NEC group than in NET group, which indicated highly malignancy of the NEC. The 5-year disease-free survival (DFS) rates for primary group and metastatic group were 30% and 40%, respectively (P > 0.05), while the 5-year survival rates were 35% and 66%, respectively (P > 0.05). Different tumor grade was found closely associated with 5-year DFS (P < 0.05) and overall survival (OS) (P < 0.05) in both groups. Furthermore, we found 5-year DFS of patients with primary site of the tumor located in the gastrointestinal tract was much lower than that located in pancreas (P < 0.05), while the 5-year OS showed no significant differences between two groups (P > 0.05). CONCLUSIONS Surgery is an effective method for the treatment of hepatic NET; tumor grading is an important determinant factor of prognosis.

Abstract
Nine lanostane-type triterpenoids were isolated from branches and leaves of Abies faxoniana, along with 10 known compounds. Two were isolated as inseparable mixtures of epimers at C-23 of the γ-lactone ring that had a lactol structure. The structures of the nine compounds were established by spectroscopic analysis and circular dichroism (CD) data. The absolute configurations at the stereogenic centres of two of the known compounds were confirmed by X-ray crystallography. One compound showed cytotoxic activities against HCT-116, MCF-7, and A549 cells with IC50 values of 8.9, 7.6, and 4.2μM, respectively. The isolated compounds were tested for their effects on human DNA topoisomerases I and II. One was found to be a selective inhibitor of human topo II activity with an IC50 value of 53.5μM, which was comparable to that of the topo II inhibitor etoposide (IC50=49.6μM).

Abstract
Recent progress in computational methods for inves-tigating physical and functional gene interactions has provided new insights into the complexity of biological processes. An essential part of these methods is presented visually in the form of gene interaction networks that can be valuable in exploring the mechanisms of disease. Here, a combined network based on gene pairs with an extra layer of re-liability was constructed after converting and combining the gene pair scores using a novel algorithm across multiple approaches. Four groups of kidney cancer data sets from ArrayExpress were downloaded and analyzed to identify differentially expressed genes using a rank prod-ucts analysis tool. Gene co-expression network, protein-protein interac-tion, co-occurrence network and a combined network were constructed using empirical Bayesian meta-analysis approach, Search Tool for the Retrieval of Interacting Genes/Proteins (STRING) database, an odds ratio formula of the cBioPortal for Cancer Genomics and a novel rank algorithm with combined score, respectively. The topological features of these networks were then compared to evaluate their performances. The results indicated that the gene pairs and their relationship rank-ings were not uniform. The values of topological parameters, such as clustering coefficient and the fitting coefficient R(2) of interaction net-work constructed using our ranked based combination score, were much greater than the other networks. The combined network had a classic small world property which transferred information quickly and displayed great resilience to the dysfunction of low-degree hubs with high-clustering and short average path length. It also followed distinct-ly a scale-free network with a higher reliability.
