ABSTRACT

Background: Sepsis surveillance was important for resources allocation, prevention, and development of health policy. Objective: The aim of the study was to validate a modified International Classification of Diseases (ICD)-10 based algorithm for identifying hospitalized patients with sepsis. Methods: We retrospectively analyzed a prospective, single-center cohort of adult patients who were consecutively admitted to one medical ICU ward and ten non-ICU wards with suspected or confirmed infections during a 6-month period. A modified ICD-10 based algorithm was validated against a reference standard of Sequential Organ Failure Assessment (SOFA) score based on Sepsis-3. Sensitivity (SE), specificity (SP), positive predictive value (PPV), negative predictive value (NPV), and areas under the receiver operating characteristic curves (AUROCs) were calculated for modified ICD-10 criteria, eSOFA criteria, Martin's criteria, and Angus's criteria. Results: Of the 547 patients in the cohort, 332 (61%) patients met Sepsis-3 criteria and 274 (50%) met modified ICD-10 criteria. In the ICU setting, modified ICD-10 criteria had SE (84.47%), SP (88.57%), PPV (95.60), and NPV (65.96). In non-ICU settings, modified ICD-10 had SE (64.19%), SP (80.00%), PPV (80.33), and NPV (63.72). In the whole cohort, the AUROCs of modified ICD-10 criteria, eSOFA, Angus's criteria, and Martin's criteria were 0.76, 0.75, 0.62, and 0.62, respectively. Conclusion: This study demonstrated that modified ICD-10 criteria had higher validity compared with Angus's criteria and Martin's criteria. Validity of the modified ICD-10 criteria was similar to eSOFA criteria. Modified ICD-10 algorithm can be used to provide an accurate estimate of population-based sepsis burden of China.

ABSTRACT

High infiltration of M2-polarized macrophages in the primary tumor indicates unfavorable prognosis and poor overall survival in the patients with triple-negative breast cancer (TNBC). Thus, reversing M2-polarized tumor-associated macrophages in the tumors has been considered as a potential therapeutic strategy for TNBC. Sphingomyelin synthase 2 (SMS2) is the key enzyme for sphingomyelin production, which plays an important role in plasma membrane integrity and function. In this study we investigated whether SMS2 inhibitor or SMS2 gene knockout could reduce macrophages M2 polarization and tumor progression in a mouse model of TNBC. We showed that SMS2 mRNA expression was linked to immunosuppressive tumor microenvironment and poor prognosis in TNBC patients. The knockout of SMS2 or application of 15w (a specific SMS2 inhibitor) markedly decreased the generation of M2-type macrophages in vitro, and reduced the tumor weight and lung metastatic niche formation in a 4T1-TNBC mouse model. We further demonstrated that the in vivo antitumor efficacy of 15w was accompanied by a multifaceted remodeling of tumor immune environment reflecting not only the suppression of M2-type macrophages but also diminished levels of regulatory T cells and myeloid-derived suppressor cells leading to a dramatically improved infiltration of antitumor CD8+ T lymphocytes. Collectively, our results reveal a novel and important role of SMS2 in the protumorigenic function and may offer a new strategy for macrophage-targeted anticancer therapy.

ABSTRACT

BACKGROUND: Stem cell therapy has revealed a promising future for treating erectile dysfunction (ED), but the fate and curative mechanism of intracavernosal transplanted stem cells are under further exploration. This study aimed to demonstrate the effects of myocardin gene modification on improving erectile function and prolonging the retention of implanted adipose-derived stem cells (ASCs) using in vivo small animal imaging. METHODS: ASCs were isolated, cultured, and identified by flow cytometry and osteogenic and adipogenic induction. The effects of gene modification on cell proliferation, apoptosis, and contraction were determined by CCK-8, EdU, flow cytometry, and collagen gel lattice contraction assays as well as confocal microscopy. A total of 20 normal and 60 diabetes mellitus ED to (DMED) Sprague-Dawley rats were recruited to the 7 day and 21 day groups. Each group contained subgroups of 10 rats each: the negative control (NC), DMED + ASCs plus Ad-Luc-Myocardin, DMED + ASCs plus Ad-Luc, and DMED + phosphate buffer solution (PBS) groups. Erectile function was evaluated with the intracavernosal pressure/mean arterial pressure (△ICP/MAP) ratio. In vivo small animal imaging and an EdU cell tracking strategy were introduced to detect the transplanted ASCs, and IHC and WB were performed to assess smooth muscle cell protein levels. RESULTS: The ASCs expressed high CD29 and CD90 and scant CD45, while the multi-induction potential was verified by oil red O and alizarin red staining. Gene transfection of myocardin had no significant influence on ASC apoptosis but inhibited cell proliferation and promoted cell contraction. Myocardin combined with ASCs enhanced the therapeutic potential of ASCs for improving the △ICP/MAP ratio as well as α-SMA and calponin expression. In vivo imaging confirmed that ASCs resided within the cavernous body in 21 days, while only a few red EdU dots were detected. CONCLUSIONS: Myocardin induced ASC differentiation towards smooth muscle-like cells and enhanced the therapeutic potential of ASCs for ameliorating ED in STZ-induced diabetic rats. Notably, in vivo small animal tracking was an effective strategy for monitoring the implanted stem cells, and this strategy might have advantages over traditional EdU assays.

ABSTRACT

OBJECTIVE: As a non-competitive N-methyl-d-aspartate receptor antagonist, memantine has been used to treat major mental disorders including schizophrenia, bipolar disorder, and major depressive disorder (MDD). This meta-analysis systematically investigated the effectiveness and tolerability of adjunctive memantine for patients with schizophrenia, bipolar disorder, and MDD. METHODS: Only randomized controlled trials (RCTs) were identified and included in the study. Data of the three disorders were separately synthesized using the RevMan 5.3 software. RESULTS: Fifteen RCTs (n = 988) examining memantine (5-20 mg/day) as an adjunct treatment for schizophrenia (9 trials with 512 patients), bipolar disorder (3 trials with 319 patients), and MDD (3 trials with 157 patients) were analyzed. Memantine outperformed the comparator regarding total psychopathology with a standardized mean difference (SMD) of -0.56 [95% confidence interval (CI): -1.01, -0.11; I2 = 76%, P = 0.01] and negative symptoms with an SMD of -0.71 (95% CI: -1.09, -0.33; I2 = 74%, P = 0.0003) in schizophrenia, but no significant effects were found with regard to positive symptoms and general psychopathology in schizophrenia, or depressive and manic symptoms in bipolar disorder or depressive symptoms in MDD. Memantine outperformed the comparator in improving cognitive performance in schizophrenia with an SMD of 1.07 (95% CI: 0.53, 1.61; P < 0.0001, I2 = 29%). No group differences were found in the rates of adverse drug reactions and discontinuation due to any reason in the three major mental disorders. CONCLUSIONS: Memantine as an adjunct treatment appears to have significant efficacy in improving negative symptoms in schizophrenia. The efficacy and safety of adjunctive memantine for bipolar disorder or MDD needs to be further examined. REVIEW REGISTRATION: PROSPERO: 42018099045.

ABSTRACT

BACKGROUND: Adjunctive ketamine with electroconvulsive therapy (ECT) has been investigated for treating major depressive disorder (MDD), but the findings have been inconsistent. AIM: This is an updated meta-analysis of the efficacy and safety of ketamine augmentation of ECT in the treatment of MDD. METHODS: Randomized controlled trials (RCTs) reporting on the efficacy and safety of ketamine and ECT were identified and analyzed. RESULTS: Seventeen RCTs (n = 1,035) compared ketamine alone or ketamine plus other anesthetic drugs (n = 557) with other anesthetic agents (n = 478) in MDD patients who received ECT. Ketamine+other anesthetic drugs was superior in improving depressive symptoms over other anesthetic medications at early study time point, but not at post-ECT or end of study time points. Ketamine alone was not more efficacious in treating depressive symptoms than other anesthetic drugs at early study, post-ECT and end of study time points. Sensitivity analysis and 19 of the 20 subgroup analyses also confirmed the lack of significance of these findings. Eleven RCTs testing the effects of ketamine on neurocognitive functions with various test batteries found mixed results. Ketamine alone significantly increased blood pressure more than other anesthetic drugs in MDD treated with ECT. CONCLUSION: Compared to other anesthetic agents, ketamine alone does not appear to improve the efficacy of ECT. However, ketamine+other anesthetic combinations may confer a short-term advantage in improving depressive symptom at the early stages of ECT.

ABSTRACT

An efficient iodocarbocyclization of alkenes for the synthesis of iodooxindoles has been developed. This reaction proceeds in a chemoselective manner and shows excellent tolerance of various functional groups, including a chemosensitive hydroxymethyl group. Nonmetal inorganic iodine pentoxide was used as both the oxidant and iodine source, making this protocol very practical. On the basis of experimental observations, a plausible electrophilic reaction mechanism was proposed.

ABSTRACT

An efficient oxidative aminooxyarylation of alkenes under a transition-metal-free condition was described. Under the reaction conditions, N-hydroxyphthalimide (NHPI) reacted readily with N-arylacrylamides to produce cyclic products via a radical C-H functionalization process, achieving both C-O and C-C bonds formation in one pot. This reaction provided a facile access to the valuable aminooxylated oxindoles. The benzylic and α-methylene C(sp3)-H bonds were also aminooxylated under the reaction conditions.

ABSTRACT

Toll-like receptor 5 (TLR5) is an important receptor that interacts with bacterial flagellin and regulates host immune response in mammal. Recent studies demonstrate that piscine contains two types of TLR5, namely membrane form of TLR5 (TLR5M) and soluble form of TLR5 (TLR5S), and both of which perform crucial role in flagellin response. In the present study, a TLR5M and a TLR5S sequence was cloned from orange-spotted grouper (Epinepheluscoioides), and their ORFs are respectively 2466 bp (821 aas) and 1935 bp (644 aas). EcTLR5M has the typical TLR structure of a LRR domain, a transmembrane region and a TIR domain, while EcTLR5S only contains a LRR domain like other species' TLR5S. Both molecules have 23 LRR motifs, a LRR-NT and a LRR-CT in the LRR domain, similar to those of other species. Phylogenetic and sequence alignment indicated that both EcTLR5s respectively displayed closer relationship and higher sequence identity with those in other fish species. In healthy grouper, EcTLR5M was highly expressed in the skin, head kidney and spleen, while EcTLR5S was mainly detected in the liver. Ciliate Cryptocaryon irritans infection could significantly up-regulate the expression level of EcTLR5s in the gill and spleen from day 1 to day 3, and higher expression fold change was observed in the spleen. Taken together, the present studies contributed to understanding the function of piscine TLR5M/S and clarify their possible role in fish immune response against ciliate infection.

ABSTRACT

OBJECTIVE: To investigate whether phenotypic modulation of bladder smooth muscle occurs in diabetic rats. METHODS: Thirty-two male SD rats were randomly assigned into diabetic group and control group. Diabetic rat models were established by a single intraperitoneal injection of streptozotocin (60 mg/kg). Nine weeks later, the bladder tissues of the rats were examined for structural changes using HE and Masson's trichrome staining , and the expressions of myocardin, α-SMA, and SMMHC in bladder smooth muscles were detected with RT-PCR and Western blotting. RESULTS: Compared with the control group, the diabetic rats showed obvious polydipsia and polyuria with significantly increased collagenous fibers and lowered expressions of myocardin, α-SMA, and SMMHC in the bladder tissue (P<0.05). CONCLUSION: s In rats at 9 weeks after diabetic model establishment, phenotypic transition of the bladder smooth muscles occurs to cause bladder contractile dysfunction, which may play an important role in the pathology of diabetic bladder dysfunction.

ABSTRACT

OBJECTIVE: To evaluate the effects and safety of transperitoneal laparoscopic radical prostatectomy (TLRP) and extraperitoneal laparoscopic radical prostatectomy (ELRP) in the treatment of localized prostate cancer. METHODS: We searched the Cochrane Library, Medline, Chinese Journal Full-text Database, Wanfang and CBM for clinical controlled trials addressing TLRP and ELRP in the treatment of localized prostate cancer. Two independent reviewers extracted comparable data from eligible studies and performed meta-analysis with the Statal 2.0 software on the relevant indexes of operation time, intraoperative blood loss, postoperative catheterization, postoperative intestinal function recovery, and postoperative hospital stay. RESULTS: Nine clinical controlled trials with 942 cases were included in this analysis, 492 treated by TLRP and the other 450 by ELRP. Meta-analysis showed no statistically significant differences between the TLRP and ELRP groups in operation time (SMD = 0.60, 95% CI: -0.06,1.26), intraoperative blood loss (SMD = 0.01, 95% CI: -0.35, 0.36) , postoperative catheterization time (SMD = 0.10, 95% CI: -0.21, 0.40) and postoperative hospital stay (SMD = 0.45, 95% CI: -0.01, 0.91), except in the time of postoperative intestinal function recovery, which was significantly shorter in the ELRP than in the TLRP group (SMD = 1.18, 95% CI: 0.26, 2.10). CONCLUSION: For the treatment of localized prostate cancer, ELRP is similar to TLRP with respect to operation time, intraoperative blood loss, postoperative catheterization and postoperative hospital stay, but superior to the latter in postoperative intestinal function recovery.

ABSTRACT

OBJECTIVE: To explore the effect of the calcitonin gene related peptide (CGRP) on the phenotypic transformation of corpus cavernosum smooth muscle cells (CCSM) in diabetic rats with erectile dysfunction (ED). METHODS: Models of diabetes and diabetic ED were established in male Sprague-Dawley rats by administration of streptozotocin, and CCSMs were primarily cultured and subjected to immunocytochemical assay. The cells were divided into a diabetic ED and a normal control group, and exposed to 0, 10, 60 and 100 nmol/L of CGRP for 24 hours. Then the relative expressions of calponin 1 (Cnn1) and osteopontin (OPN) mRNA were determined by real-time fluorescence quantitative RT-PCR (qRT-PCR). RESULTS: The rate of SMalpha-actin positive cells in the CCSMs was (95.94 +/- 0.03) %. The expression of Cnn1 mRNA was significantly lower while that of OPN mRNA remarkably higher in the diabetic ED rats (4.41 +/- 0.29 and 5.28 +/- 0.32) than in the normal controls (10.35 +/- 0.62 and 1.32 +/- 0.24) (P < 0.01). Exposure to 100 nmol/L of CGRP significantly upregulated the expression of Cnn1 mRNA and downregulated that of OPN mRNA as compared with the unexposed rats (6.9 +/- 0.22 vs 4.41 +/- 0.29 and 3.26 +/- 0.31 vs 5.28 +/- 0.32, P < 0.01). CONCLUSION: CGRP can transform the phenotype of CCSMs in diabetic ED rats from contractile to synthetic type.

ABSTRACT

OBJECTIVE: To investigate the role of miR-145 in the corpus cavernosum smooth muscle tissue in the pathogenesis of erectile dysfunction (ED) in diabetic rats. METHODS: The total RNA was extracted from the corpus cavernosum of a diabetic rat model with ED, diabetic rats with normal erectile function and normal rats, and the expression levels of miR145 were compared between the groups. RESULTS: The expression of miR-145 was decreased in the corpus cavernosum of diabetic rats with ED. CONCLUSION: Diabetes mellitus can cause ED in rats, in which process decreased expression of miR145 in the corpus cavernosum may play a role.

ABSTRACT

OBJECTIVE: To investigate the changes of gene expression profiles associated with erectile dysfunction in diabetic rats. METHODS: Affymetrix Gene Chip arrays from the Gene Expression Omnibus (GEO) were used to examine the alterations in the gene expression profiles between streptozotocin-induced diabetic rats and littermate controls, and the data were analyzed with GeneSifter microarray analysis software. RESULTS: A total of 661 differentially expressed genes were identified, including 280 up-regulated and 381 down-regulated ones. Among the differentially expressed genes, kruppel-like factor 5 (klf5) was upregulated by 4.01 folds and ceruloplasmin(cp) by 5.14 folds; collagen, type XI, alpha1 was down-regulated by 5.84 folds and collagen, type I, alpha1 by 5.77 folds. The 661 differentially expressed genes involved such functional processes as glycoprotein biosynthesis, collagen fibril organization, angiogenesis in wound healing, triglyceride metabolism, cell proliferation and other important biological processes, and some pathways also involved such as fatty acid metabolism, neurodegenerative disorders, and ECM-receptor interactions. CONCLUSION: Some genes such as klf5, cp, and collagen play important roles in the pathophysiology of diabetes-induced erectile dysfunction. Bioinformatic approaches offer a new means for identifying candidate genes and pathways relevant to the pathophysiology of diabetes-induced erectile dysfunction, highlighting also the potential complexity of this disorder.
