Genome-wide identification of GSK gene family in Senna tora L. and expression analyses / 药学学报

Glycogen synthase kinase 3/SHAGGY-like kinase (GSK3) proteins play important roles in regulating plant growth, development, and stress response. In order to reveal the characteristics of GSK family members in the medicinal plant Senna tora L., in this study, we conducted the identification and expression analyses of GSKs in S. tora based on its whole genome data, combined with bioinformatics and gene expression research methods. The results showed that a total of nine S. tora GSK genes were identified, all of which contained the GSK characteristic kinase domains. All members were distributed on six chromosomes, the encoding amino acid length ranged from 465 to 943 aa, the protein molecular weight was from 33.57 to 88.83 kDa, and the average isoelectric point was 8.2. The StoSKs were divided into four evolutionary branches, and the StoSKs in the same evolutionary branch shared the same exon/intron structure and conserved motifs. The expansion of the StoSKs gene family was mainly due to segment duplication events, and there were 17, 11, 8 and 7 pairs of collinear genes with Glycine max, Medicago truncatula, Arabidopsis thaliana and Oryza sativa, respectively. The promoter regions of StoSKs mostly contained responses elements related to stress stimulation, growth and development, and hormone induction. Transcriptome data analysis showed that StoSKs were expressed in different tissues, with the highest expression level in roots. Quantitative real-time PCR (qRT-PCR) analysis indicated that StoSKs in different evolutionary branches displayed a synergistic expression pattern response to light, and most of StoSKs could rapidly respond to NaCl stress with significantly up-regulated expression. All the results provide a basis for further analysis of the biological functions of the GSKs gene family in S. tora.

Sperm acrosin activity may be a useful factor in choosing between ICSI and IVF for infertile male patients / 亚洲男科学杂志(英文版)

The clinical applications of acrosin activity are limited. We analyzed 61 578 male partners in infertile couples who visited the outpatient department of the Reproductive and Genetic Hospital of CITIC-Xiangya (Changsha, China) between August 2014 and December 2019 to determine the reference ranges and thresholds for acrosin activity in infertile Chinese men; to determine whether correlations exist between acrosin activity and age, sperm concentration, sperm morphology, or sperm motility; and to evaluate whether acrosin activity could serve as an effective prognostic indicator for choosing between in vitro fertilization (IVF) and intracytoplasmic sperm injection (ICSI) in the clinic. The cut-off value for the normal reference range of acrosin activity for male partners in infertile couples was 24.78 μIU per 106 sperm. There was no significant association between acrosin activity and age, sperm concentration, semen volume, total sperm count, progressive motility, or total motile spermatozoa. A weak positive correlation was found between acrosin activity and normal sperm morphology. There was a statistically significant difference in abnormal acrosome morphology between the group with high acrosin activity (>24.78 μIU per 106 sperm) and the group with low acrosin activity (<24.78 μIU per 106 sperm). The group with a low IVF fertilization rate had a high index of abnormal acrosomal morphology at 21.2%, while the group with a high IVF fertilization rate had a low index of 0.2%. At an acrosin activity of <24.78 µIU per 106 sperm, in one cycle of the same patient, the fertilization rate, normal fertilization rate, and good-quality embryo rate for ICSI were significantly higher than those for IVF. Therefore, the most promising application of acrosin activity could be in the selection of ICSI over IVF for infertile male patients with complete fertilization failure or a low fertilization rate.

Research progress in drugs targeting 5-lipoxygenase for age-related diseases / 生理学报

With the acceleration of aging society, delaying aging or promoting healthy aging has become a major demand for human health. 5-Lipoxygenase (5-LOX) is a key enzyme catalyzing arachidonic acid into leukotrienes (LTs), which is a potent mediator of the inflammatory response. Previous studies showed that abnormal activation of 5-LOX and overproduction of LTs are closely related to the occurrence and development of aging-related inflammatory diseases. Therefore, inhibiting 5-LOX activation is a possibly potential strategy for treating age-related diseases. In this paper, the latest research progress in 5-LOX activation, 5-LOX in mediating aging-related diseases and its small molecule inhibitors is briefly reviewed to provide scientific theoretical basis and new ideas for the prevention and treatment of aging-related inflammatory diseases.

Effects of milnacipran and paroxetine on anxiety state and headache severity of patients with generalized anxiety disorder / 中国医师进修杂志

Objective:To compare the effects of milnacipran and paroxetine on anxiety state and headache severity of patients with generalized anxiety disorder (GAD).Methods:Ninety-six patients with GAD treated in Zaozhuang Mental Health Center from January 2019 to September 2020 were selected and randomly divided into the paroxetine group (treatment with oral paroxetine) and the milnacipran group (treatment with oral milnacipran), each group with 48 cases. A course of treatment consists of 4 weeks. After 3 months of regular medication, the clinical efficacy, Hamilton Anxiety Scale (HAMA) scores, visual analogue scale (VAS) scores, migraine-specific quality of life questionnaire (MSQ V2.1) scores, and Headache Impact Test-6 (HIT-6) scores were compared between the two groups. Adverse reactions during the treatment were recorded in both groups.Results:The total effective rate in the milnacipran group at 4 weeks and 3 months after treatment were significantly higher than those in the paroxetine group: 47.92%(23/48) vs. 22.92%(11/48), χ2 = 6.56, P<0.05; 75.00%(36/48) vs. 51.47%(26/48), χ2 = 4.55, P<0.05. After treatment for 4 weeks and 3 months, the HAMA scores, VAS scores, MSQ V2.1 scores and HIT-6 scores in the milnacipran group were significantly lower than those in the paroxetine group ( P<0.05). The difference of incidence of adverse reactions in the two groups had no statistical significance ( P>0.05). Conclusions:For patients with GAD, the treatment effect of milnacipran is more significant than paroxetine, which can not only reduce patients′ anxiety state and headache degree, but also improve their specific quality of life, with high safety.

Matched-sibling donor versus unrelated umbilical cord blood transplantation for treating hematological malignancies in children / 中国组织工程研究

BACKGROUND: In recent years, umbilical cord blood has gradually become a crucial alternative source of stem cells for related and unrelated bone marrow or peripheral blood hematopoietic stem cell transplantation, which is increasingly used in the treatment of hematological malignancies in children. OBJECTIVE: To compare the clinical efficacy of sibling donor umbilical cord blood transplantation and unrelated umbilical cord blood transplantation for treating hematological malignancies in children. METHODS: The clinical data of children with hematological malignancies who received umbilical cord blood transplantation at the Hematopoietic Stem Cell Transplantation Center of the First Affiliated Hospital of Zhengzhou University between January 1, 1998 and December 31, 2018 was retrospectively analyzed. All the patients received myelablative conditioning regimen, and cyslosporine A combined with or without mycophenolate mofetil were concurrently adopted for graft-versus-host disease prophylaxis. RESULTS AND CONCLUSION: (1) Two patients in the sibling donor umbilical cord blood transplantation group and three in the unrelated umbilical cord blood transplantation group did not attain hematological engraftment and subsequently died from infection, and other patients succeeded in hematological engraftment. The median time of neutrophil and platelet engraftment in the sibling donor umbilical cord blood transplantation and unrelated umbilical cord blood transplantation groups was [17 days (11-43 days), 18 days (12-45 days), P=0.307] and [20.5 days (15-50 days), 27 days (18-56 days), P=0.773]. There was no significant difference between the two groups. (2) The incidence of acute graft-versus-host disease and chronic graft-versus-host disease in the sibling donor umbilical cord blood transplantation and unrelated umbilical cord blood transplantation groups was 36% vs. 43% (P=0.737) and 15% vs. 33% (P=0.412). There was no significant difference between the two groups. There was also no significant difference in the incidence of infection after transplantation between sibling donor umbilical cord blood transplantation and unrelated umbilical cord blood transplantation groups (56% vs. 71%, P=0.343). (3) There were no significant differences in the 2-year overall survival (61% vs. 36%, P=0.301), or 2-year relapse-free survival (56% vs. 33%, P=0.151). The 5-year overall survival and 5-year relapse-free survival in the sibling donor umbilical cord blood transplantation and unrelated umbilical cord blood transplantation groups were 54% vs. 24% (P=0.044) and 50% vs. 20% (P=0.039). The results showed that there was a significant difference in long-term survival rate between two groups. (4) Our results reveal that both sibling donor umbilical cord blood transplantation and unrelated umbilical cord blood transplantation are safe, effective and applicable for children with hematological malignancies. In particular, there are significant benefits in the long-term survival of substitute donor transplantation for pediatric patients with hematological malignancies.

Report Quality of Clinical Practice Guidelines of Rehabilitation Based on RIGHT / 中国康复理论与实践

@#Objective To evaluate the quality of reporting of clinical practice guidelines of rehabilitation.Methods A comprehensive retrieve was performed in electronic databases of PubMed, EMBASE, CNKI, China Biology Medicine disc, Wanfang data, etc., from January 1, 2017 to January 11, 2020. Supplementary searches had been done on relevant websites. Two researchers reviewed literatures and assessed the reporting quality independently by using Reporting Items for Practice Guidelines in Healthcare (RIGHT), and any disagreements needed to be discussed in a consensus meeting.Results A total of 16 guidelines were included, with an average reporting rate of (44.8±27.9)%. Among the seven domains of RIGHT, basic information was reported the highest (57.3%), and evidence (31.3%) and other information (31.3%) was the lowest. The reporting rate was less as the guidelines published in China than in foreign contries (OR = 0.80, 95%CI 0.56-1.16), in original version than in update version (OR = 0.79, 95%CI 0.54-1.16); and higher as developed by various societies or associations than developed by non-societies or associations (OR = 1.15, 95%CI 0.82-1.61), however, no statistically significant difference was found in above comparisons.Conclusion Current clinical practice guidelines of rehabilitation reported with low quality. It is proposed that future guideline developers should report guidelines after RIGHT statements, including key information and content, in order to improve the quality of reporting guidelines.

Sevoflurane effect on cognitive function and the expression of oxidative stress response proteins in elderly patients undergoing radical surgery for lung cancer

Objective: To investigate the effects of sustained inhalation of sevoflurane on cognitive function and the expression of oxidative stress response proteins such as NADPH oxidase subunits NOX2 and NOX4 in elderly patients undergoing radical surgery for lung cancer

Study Design: An experimental study

Place And Duration Of Study: Department of Anesthesiology, Suzhou Kowloon Hospital, Shanghai Jiao Tong University School of Medicine, China, from February 2016 to October 2017

Methodology: Elderly patients who underwent radical surgery for lung cancer were divided into the sevoflurane group and the propofol group, with 52 cases in each group. Sustained inhalation of sevoflurane and propofol was administered to maintain anesthesia in the respective groups. Cognitive function and lung function parameters were compared between the two groups. Serum S100 beta levels and expression of NOX2 and NOX4 proteins in peripheral blood mononuclear cells of the two groups were determined

Results: At 24 hours after surgery, the lung function indices of the sevoflurane group such as FEV1, FVC and VC were higher than those of the propofol group [p<0.001, p=0.008 and p=0.002, respectively]. At the end of the surgery and at 24 hours after surgery, the MMSE scores of the sevoflurane group were higher than the propofol group [all p< levels were lower than the propofol group [p=0.003 and p?0.001]. S100<0.001, respectively]. Levels of NADPH oxidase subunits NOX2 and NOX4 proteins in peripheral blood mononuclear cells of the sevoflurane group were lower than the propofol group [p=0.033, p<0.001, p<0.001and p<0.001, respectively]

Conclusion: Compared with intravenous anesthesia with propofol, general anesthesia with sevoflurane inhalation has little effect on the short-term cognitive function in elderly patients undergoing radical surgery for lung cancer, and can effectively improve lung function. The mechanism may be related to the reduction of the expression of NOX2 and NOX4 proteins

Alcohol promotes renal fibrosis by activating Nox-mediated DNA methylation of Smad7 / 中国药理学与毒理学杂志

OBJECTIVE Alcohol is mainly metabolized through liver and excreted by kidney in the body. Kidney damage has been considered as the secondary to liver injury and kidney dysfunction is common in hospitalized patients with severe alcoholic hepatitis. Both acute and chronic alcoholism accumulation can compromise kidney function, although alcoholic kidney disease has drawn much more attention recently,the methodology for establishing the in vivo and in vitro alcoholic renal fibrosis models are still lacking,and the underlying mechanisms are to be determined. METHODS and RESULTS Mice were feed with a liquid diet containing alcohol for 4 weeks, 8 weeks and 12 weeks respectively, results of Masson′s Trichrome staining showed that kidney fibrosis peaked in 8-week model group, which consistent with the results of albumin assay,Western blot,immunostaining and real-time PCR of collagen I and α-SMA.In vitro study also confirmed that ethanol upregulated the level of fibrotic index-es,including collagen I and α-SMA,in tubular epithelial cells(HK2 cells).Additionally,both in vivo and in vitro studies showed that Smad7 was decreased and Smad3 was highly activated. Then we further detected the underlying mechanisms by which alcohol induced the imbalance of Smad7 and Smad3. Results of Genome-wide methylation sequencing found DNA methylation of Smad7 in the alcoholic fibrosis kidney,which may be mainly mediated by DNA methyltransferase 1(DNMT1),because knock-down of DNMT1,but not DNMT2 and 3,largely restored Smad7 level in ethanol-treated HK2 cells.Con-sequently, we found that NADPH Oxidases (nox)-mediated oxidative stress is the major force upregu-lating DNMT1,since knockdown of Nox2 and 4 could both decrease DNMT1 while rebalancing Smad7/Smad3 axis, and thereby relieved ethanol-induced fibrotic response in HK2 cells. More importantly, intraperitoneal injection of apocynin,an inhibitor of NADPH oxidoreductase,attenuated renal fibrosis in alcoholic kidney fibrosis mouse model. CONCLUSION By establishing the novel in vivo and in vitro models,we found that through activating oxidative stress-induced DNA methylation of Smad7,alcohol induces renal fibrosis by breaking the balance between Smad7 and Smad3.Elimination of Nox-mediated oxidative stress may be a potential therapy for treatment of long-term alcohol abuse-induced kidney fibrosis.

Inhibition effect and mechanism of IL-8 down-regulation on migration of esophageal squamous cell carcinoma KYSE170 cells / 中国肿瘤生物治疗杂志

@# Objective: To investigate the effect of interleukin-8 (IL-8) on esophageal cancer cell line KYSE170, and to preliminarily explore its mechanism. Methods: siRNA targeting IL-8 was in vitro synthesized and transfected into KYSE170 cells by lipofectamine 2000. The efficiency of silencing was determined by Real-time PCR, Western blotting and ELISA. Morphological changes of KYSE170 cells were observed microscopically. Scratch assay was performed to observe the cell migration ability. CCK-8 assay was used to detect the cell proliferation ability. Western blotting was used to detect the expressions of IL-8 receptor and JAK2-STAT3 signaling pathway related proteins. Results: Compared with the negative control group, the mRNA and protein expressions of IL-8 in KYSE170 cells were all significantly decreased after IL-8 silencing (P<0.01), and IL-8 secretion was significantly reduced (P<0.01).After IL-8 gene silencing, the migration capacity of KYSE170 cells was significantly weakened (P<0.01), while no significant changes in cell proliferation was detected. The expression of IL-8 receptor 2 (CXCR2) and transfer-related protein WASF3 were significantly decreased (P< 0.05), while the expression of IL-8 receptor 1 (CXCR1) was not significantly changed; the expressions of p-JAK2 and p-STAT3 protein in JAK2-STAT3 signaling pathway were significantly decreased (all P<0.01). Conclusion: Knock-down of IL-8 inhibits the migration of esophageal cancer KYSE170 cells, and the mechanism may be related with the alteration of CXCR2 and its downstream JAK2STAT3 signaling pathway.
