Background: As the Diagnostic and Statistical Manual of Mental Disorders fifth version (DSM-5) was published, the Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime version (K-SADS-PL) was modified to adapt the new version (K-SADS-PL DSM-5). We translated it to Chinese (K-SADS-PL-C DSM-5) and described its reliability and validity.Methods: A total of 154 groups of 6 to 18-year-old children and their guardians were included. Trained interviewers interviewed subjects using the K-SADS-PL-C DSM-5. Interrater reliability was assessed by audio recording. Parent-reported scales, like child behavior checklist (CBCL), the Chinese version of Swan-son Nolan and Pelham, version IV scale-parent form (SNAP-IV), social responsiveness scale (SRS-1), and children-reported scales like depression self-rating scale for children (DSRSC) and the screen for child anxiety related emotional disorders (SCARED) were used to examine the validity of depressive disorder, ADHD, ASD, and ODD.Results: The K-SADS-PL-C DSM-5 had fair to excellent interrater (0.537-1.000) and test-retest (0.468-0.885) reliability of affective disorder and neurodevelopment disorder. The convergent validity of affective disorder and neurodevelopment disorder was good, and their divergent validity was acceptable.Limitations: i) Clinical questionnaires were insensitive in classifying disorders and had limitations in derived diagnoses. ii) Samples only came from clinical environment, iii) covered limited disease species, and iv) were small.Conclusion: The K-SADS-PL-C DSM-5 can support reliable and valid diagnoses for children with affect, neurodevelopmental, and behavioral disorders in China.

[Objectives] To understand how cold tolerance is influenced by altitude and ice nucleating active bacteria (INA) in high altitude environments. Methods: Field conditions were simulated in a laboratory to study the effects of varying the super-cooling point (SCP) and freezing point (FP) of Evergestis extimalis.Results: Super cooling point declined gradually with altitude. For example, the SCP of E. extimalis from Le Du (1 900 m ASL), Xing Ning (2 300 m ASL) and Huang Yuang (3 010 m ASL) were 12.30, 13.39 and14.56, respectively. Variation of SCP and freezing point were correlated with local temperature. The SCP of E. extimalis increased after INA treatment. E. extimalis in the following treatment groups; INA1-1 (Pseudomonas syringae), INA2-1 (P. syringae), INA3-1 (Erwinia pyrifoliae) and the control, had SCPs of -10.72, -13.73, -14.04 and -14.39, respectively in Feb. 2014. Mortality in the INA1-1, INA2-1, INA3-1 treatment groups and the control were 29.09%-36.17%,33.16% and 27.44%, respectively on Nov. 2013.Conclusion: The SCP of E. extimalis decreased with increasing altitude. INA treatment dramatically reduced mortality and increased the SCP of E. extimalis. [ABSTRACT FROM AUTHOR]

Most studies of mixed culture fermentation for hydrogen production focus on the metabolite distribution under different operational conditions. While, the corresponding microbial dynamics research is limited. The aim of this work was to reveal the microbial community dynamics of extreme-thermophilic mixed culture enriched in a chemostat for hydrogen production with the combining molecular tools of denaturing gradient gel electrophoresis (DGGE), Illumina Miseq high-throughput sequencing platform, and 16S rRNA clone library sequencing. The analyzed results showed that the genera of Caldanaerobius, Caldicellulosiruptor and/or Thermoanaerobacter dominated the bacteria. While archaea were not detected even by Illumina Miseq high-throughput sequencing. The effects of hydrogen partial pressure or pH increasing from 5.5 to 7.0 on the microbial communities were not notably, and genera of Caldicellulosiruptor and Thermoanaerobacter were the dominants. High hydrogen yield in this chemostat was attributed to the enrichment of Caldicellulosiruptor . While Caldanaerobius dominated the bacteria communities as pH decreased to 4.5. Caldanaerobius and Thermoanaerobacter dominated at high influent glucose concentrations. Thereby, it clearly indicated that the microbial dynamics shall be considered when analyzing the extreme-thermophilic mixed culture fermentation in the future. [ABSTRACT FROM AUTHOR]

Abstract: The effect of berberine hydrochloride (BBR) on inducible cyclooxygenase-2 (COX-2) in small intestinal mucosa and related mechanisms was investigated in a rat model of acute endotoxemia. The results showed that lipopolysaccharide (LPS) increased COX-2 expression, whereas SB202190 and BBR curtailed it. LPS increased phosphorylation of mucosal p38 MAPK and ATF2 as well as production of ATF2, whereas BBR attenuated these effects. LPS upregulated mucosal peroxisome proliferator-activated receptor gamma (PPARγ), but BBR reduced this receptor. GW9662 aggravated LPS-induced and reversed BBR-attenuated COX-2 expression. The findings showed that BBR ameliorated COX-2 overexpression partially via modulation of p38 and PPARγ pathways during acute endotoxemia. [Copyright &y& Elsevier]

Vernoramyosides A-F (1 – 6), six new Δ7,9(11) stigmastane-type steroid saponins, along with four known analogues (7 – 10) were isolated from the leaves of Vernonia amygdalina Delile (Compositae). Their structures were determined by the combination of NMR, ECD and HR-ESI-MS data. These compounds all possessed highly oxidized side chain and a γ-lactam or α , β -unsaturated five-membered lactone ring. All isolates were screened for their activities in reversing resistance in MCF/DOX cells. [Display omitted] [ABSTRACT FROM AUTHOR]

Background: Acute mesenteric venous thrombosis (AMVT) can cause a poor prognosis. Prompt transcatheter thrombolysis (TT) can achieve early mesenteric revascularization. However, irreversible intestinal ischemia still occurs and the mechanism is still unclear., Aim: To evaluate the clinical outcomes of and to identify predictive factors for irreversible intestinal ischemia requiring surgical resection in AMVT patients treated by TT., Methods: The records of consecutive patients with AMVT treated by TT from January 2010 to October 2017 were retrospectively analyzed. We compared patients who required resection of irreversible intestinal ischemia to patients who did not require., Results: Among 58 patients, prompt TT was carried out 28.5 h after admission. A total of 42 (72.4%) patients underwent arteriovenous combined thrombolysis, and 16 (27.6%) underwent arterial thrombolysis alone. The overall 30-d mortality rate was 8.6%. Irreversible intestinal ischemia was indicated in 32 (55.2%) patients, who had a higher 30-d mortality and a longer in-hospital stay than patients without resection. The significant independent predictors of irreversible intestinal ischemia were Acute Physiology and Chronic Health Evaluation (APACHE) II score (odds ratio = 2.368, 95% confidence interval: 1.047-5.357, P = 0.038) and leukocytosis (odds ratio = 2.058, 95% confidence interval: 1.085-3.903, P = 0.027). Using the receiver operating characteristic curve, the cutoff values of the APACHE II score and leukocytosis for predicting the onset of irreversible intestinal ischemia were calculated to be 8.5 and 12 × 10 9 /L, respectively., Conclusion: Prompt TT could achieve a favorable outcome in AMVT patients. High APACHE II score and leukocytosis can significantly predict the occurrence of irreversible intestinal ischemia. Therefore, close monitoring of these factors may help with the early identification of patients with irreversible intestinal ischemia, in whom ultimately surgical resection is required, before the initiation of TT., Competing Interests: Conflict-of-interest statement: The authors declare that they have no conflicts of interest., (©The Author(s) 2020.

Background: Alemtuzumab has been used in organ transplantation and a variety of hematologic malignancies (especially for the treatment of B-cell chronic lymphocytic leukemia). However, serious infectious complications frequently occur after treatment. The reason for increased infections postalemtuzumab treatment is unknown at this stage. We explore the effect of alemtuzumab on intestinal intraepithelial lymphocytes (IELs) and intestinal barrier function in cynomolgus model to explain the reason of infection following alemtuzumab treatment., Methods: Twelve male cynomolguses were randomly assigned to either a treatment or control group. The treatment group received alemtuzumab (3 mg/kg, intravenous injection) while the control group received the same volume of physiological saline. Intestinal IELs were isolated from the control group and the treatment group (on day 9, 35, and 70 after treatment) for counting and flow cytometric analysis. Moreover, intestinal permeability was monitored by enzymatic spectrophotometric technique and enzyme-linked immunosorbent assay., Results: The numbers of IELs were decreased significantly on day 9 after treatment compared with the control group (0.35 ± 0.07 × 10 8 and 1.35 ± 0.09 × 10 8 , respectively; P < 0.05) and were not fully restored until day 70 after treatment. There were significant differences among four groups considering IELs subtypes. In addition, the proportion of apoptotic IELs after alemtuzumab treatment was significantly higher than in the control group (22.01 ± 3.67 and 6.01 ± 1.42, respectively; P < 0.05). Moreover, the concentration of D-lactate and endotoxin was also increased significantly on day 9 after treatment., Conclusions: Alemtuzumab treatment depletes lymphocytes in the peripheral blood and intestine of cynomolgus model. The induction of apoptosis is an important mechanism of lymphocyte depletion after alemtuzumab treatment. Notably, intestinal barrier function may be disrupted after alemtuzumab treatment.

Deregulation of the WNT signaling pathway is associated with the development and progression of breast cancer. β-catenin mutations have been found to constitutively activate β-catenin-T-cell factor (TCF) signaling in other types of cancer. β-catenin acetylation regulates β-catenin-TCF4 interaction in WNT signaling, but it remains unknown whether the acetylation of β-catenin is involved in WNT-induced proliferation of breast cancer cells. In this study, a lower level of acetylated β-catenin (K345) was observed in breast cancer tissues. WNT3A stimulated the downregulation of β-catenin acetylation and promoted the proliferation of MCF7 cells. The K345Q mutation in β-catenin inhibited WNT-induced cell growth and axin2/TCF7 upregulation in breast cancer cells. By contrast, K345R mutants could mimic deacetylated β-catenin to generate the WNT-elicited phenotype. Additionally, the acetylation of β-catenin may prime β-catenin for phosphorylation. Further investigation revealed that the deacetylase HDAC6 was responsible for WNT-induced deacetylation of β-catenin in breast cancer cells. In conclusion, the epigenetic modification of β-catenin may be essential for WNT signaling in breast cancer progression, and blocking the occurrence of β-catenin acetylation may provide a novel therapeutic approach for breast cancer.

Objective: To investigate the effects of nuclear factor kappa B (NF-kappaB) on insulin signaling in skeletal muscle cells of rat with sepsis., Methods: SD rats were randomly divided into two groups: control group and sepsis group.Sepsis model was reproduced by cecal ligation and puncture in sepsis group. At 8, 16, 24, 48 and 72 h after operation, the gastrocnemius was harvested. Conventional HE staining was used to observe the morphology of skeletal muscle cells. IRS-1 protein and tyrosine phosphorylation of IRS-1 and Ser(307) phosphorylation of IRS-1 were detected by Western Blotting and immuno-precipitation. Activities of NF-kappaB in skeletal muscle cells were detected by electrophoretic mobility shift assay., Results: Tyrosine phosphorylation of IRS-1 in sepsis group was significantly lower than in control group (P < 0.01), while Ser(307) phosphorylation of IRS-1 in sepsis group was significantly higher than in control group (P < 0.01). In sepsis group, NF-kappaB activity in skeletal muscle cells was significantly higher than in control group (P < 0.01). There was significant negative correlation between activity of NF-kappaB and tyrosine phosphorylation of IRS-1 (r = 0.972, P < 0.01). There was significant positive correlation between activities of NF-kappaB and Ser(307) phosphorylation of IRS-1 (r = 0.969, P < 0.01)., Conclusions: There is no inflammatory cell infiltrate in skeletal muscle cells with sepsis. But the activity of NF-kappaB in skeletal muscle cells is obviously enhanced, and it is closely related with disorder of insulin signaling in skeletal muscle cells of rat with sepsis.

Objective: The omega-3 polyunsaturated fatty acids (PUFAs) play a key role as immune response modulators and suppressors of immunologic functions, such as lymphocyte proliferation, cytokine production, and cell surface molecular expression in T lymphocytes, monocytes, and natural killer cells. However, little is known about the effect of omega-3 PUFAs on dendritic cells (DCs). We studied the effect of omega-3 PUFAs on DCs and the related intracellular signal transduction pathway., Methods: Dendritic cells were generated from human peripheral blood monocytes in the presence of granulocyte-macrophage colony-stimulating factors and interleukin (IL)-4 and treated with eicosapentaenoic acid (EPA), docosahexanoic acid (DHA), and stearic acid for 24 h. Lipopolysaccharide (LPS) was used for maturation of the DCs. The expressions of CD40, CD80, CD86, and human leukocyte antigen-DR (HLA-DR) were analyzed by flow cytometry; production of IL-12 and tumor necrosis factor-alpha were detected by reverse transcriptase-polymerase chain reaction and enzyme-linked immunosorbent assay. The proliferative ability of allogeneic T cells stimulated by DCs was evaluated by tritiated thymidine ((3)H-TdR). Western blot analysis of p38 mitogen-activated protein kinase was conducted., Results: The omega-3 PUFAs reduced expression levels of costimulatory molecules CD80 and CD86 and major histocompatibility complex HLA-DR. IL-12 and tumor necrosis factor-alpha levels decreased significantly in the EPA and DHA groups. EPA and DHA also significantly reduced the proliferative ability of allogeneic T cells stimulated by DCs. The omega-3 PUFAs significantly inhibited LPS-induced p38 phosphorylation., Conclusion: The omega-3 PUFAs may inhibit LPS-induced DC maturation and upregulate cytokine production. Impaired p38 mitogen-activated protein kinase activity is a potential critical intracellular signaling transduction mechanism.

Strictosidine synthase (STR) is the key enzyme involved in early steps of biosynthesis of monoterpenoid indole alkaloids. STR catalyzes the condensation of tryptamine with secologanin into strictosidine. The gene encoding STR targeted to different subcellular compartments was transiently expressed in the tobacco leaves. In vitro STR enzymatic activity was measured by the depletion of tryptamine indicated by fluorescence. The results showed that the recombinant STR was effectively expressed as soluble protein in three subcellular compartments-chloroplast, vacuole and endoplasmic reticulum in the leaves of tobacco by Western blot analysis and STR enzymatic assay.
