ABSTRACT

Objective To investigate the relieving effects of knockdown of long non-coding RNA(lncRNA)taurine up-regulated gene 1 (TUG1) on inhibiting nucleotide binding oligomerization domain like receptor protein 1 (NLRP1) inflammasome and the progression of Alzheimer’ s disease. Methods Wild-type (WT group, 10 mice) or amyloid precursor protein (APP) / presenilin-1 (PS1) transgenic mice (30 mice) with a genetic background of C57 / BL6 aged 9-10 weeks were used in this study. APP / PS1 transgenic mice were randomly divided into model group, model+lncRNA TUG1 short hairpin RNA (shRNA) group and model + shRNA non target (NT) group (n = 10) . Blood samples, cerebral cortex tissues, primary microglial cells and primary astrocytes were collected from mice 12 weeks of age on day 1 (3-month-old) and 32 weeks of age on day 1 (8-month-old), with 5 mice per group at each time point. Real-time PCR analysis was used to detect the expression levels of lncRNA TUG1 and macrophage migration inhibitory factor (MIF) mRNA in cerebral cortex tissues and primary microglial cells, and C1r and C1s mRNA levels in primary astrocytes of 3-month-old and 8-month-old mice in the above 4 groups, respectively. ELISA was used to determine the MIF in plasma samples of the above 4 groups of mice. Primary microglia and astrocytes from the cerebral cortex of 3-month-old and 8-month-old mice were co-cultured. CCK-8 method was used to determine the proliferation ability of the above cells. Western blotting was used to determine the expression levels of MIF, pro interleukin-1β (pro-IL-1β), apoptosis associated speck-like protein containing a caspase recrult domain(ASC), Caspase-1 (p20), Caspase-1 (full), NLRP1 and NLRP3 in cerebral cortex tissues of 3-month-old and 8-month-old mice. Immunofluorescent staining was used to determine amyloid beta(Aβ) in cerebral cortex of 8-month-old mice. Results At the age of 3-month-old and 8-month-old, compared with the WT group, the relative expression level of lncRNA TUG1 and MIF in cerebral cortex tissues and primary microglia of model group mice was significantly up-regulated, with primary microglial cells and astrocytes proliferation ability enhanced (P0. 05) . There was no significant difference between the model group and the model+shRNA NT group mice of all the above factors (P>0. 05) . Conclusion In APP / PS1 transgenic mice, up-regulation of lncRNA TUG1 and MIF are positively associated with the activation of NLRP1 inflammasome in mice cerebral cortex tissues and primary microglia. Knock-down of lncRNA TUG1 can ameliorate the progression of Alzheimer’ s disease.

ABSTRACT

BACKGROUND: Bladder cancer stem cells could promote the recurrence and drug resistance of bladder cancer. Numerous studies have shown that keratin 6B (KRT6B) is involved in the production and progression of tumors, and is closely related to the prognosis of tumors. OBJECTIVE: To observe the expression of keratin 6B in CD44+ bladder cancer stem cells and to show the influence of keratin 6B on proliferation, migration, and self-renewal of bladder cancer stem cells, and to further explore the effect of keratin 6B expression on the prognosis of bladder cancer patients. METHODS: (1) CD44+ 5637 bladder cancer stem cells were isolated by magnetic active cell sorting. Cancer stem cell-related gene expression of SOX2, OCT4, and NANOG was detected via real-time polymerase chain reaction. The spheroid formation assay was used to detect the ability of self-renewal of cancer stem cells in CD44+ cells. Keratin 6B expression was detected in CD44+ bladder cancer stem cells by real-time polymerase chain reaction. (2) The CD44+5637 bladder cancer stem cells were divided into two groups. In the keratin 6B siRNA group, keratin 6B small interfering RNA was transfected into CD44+ bladder cancer stem cells. Untransfected CD44+ bladder cancer stem cells were used as the black control group. Cells were collected at 2 days post-transfection. The proliferation, migration, and self-renewal capacity of keratin 6B siRNA CD44+ bladder cancer stem cells were detected by the colony and wound healing assay and spheroid formation respectively. (3) Totally 24 bladder cancer tissues were used by immunohistochemistry to analyze the expression of CD44v6 and keratin 6B. (4) ONCOMINE database was used to analyze the effect of keratin 6B expression on the overall survival of bladder cancer. RESULTS AND CONCLUSION: (1) Cancer stem cell-related genes (SOX2, OCT4, NANOG) and keratin 6B expression was higher in CD44+ cells isolated by magnetic active cell sorting compared with CD44- cells (P < 0.05). Cell proliferation, migration, and in vitro spheroid formation were significantly increased (P < 0.05). Keratin 6B small interfering RNA down-regulated the expression of keratin 6B in CD44+ bladder cancer stem cells (P < 0.05). (2) Compared with the blank control group, the proliferation and migration of CD44+ bladder cancer stem cells after transfection of keratin 6B small interfering RNA (P < 0.05), and the number of tumorsphere significantly diminished (P < 0.05); the expression of Notch1 and Hes1 mRNA increased (P < 0.05). (3) Keratin 6B and CD44v6 were significantly different in bladder cancer tissue (P=0.006). The overall survival rate of bladder cancer patients with high expression of keratin 6B was lower than that of patients with low expression of keratin 6B. (4) The results showed that keratin 6B was highly expressed in CD44+ bladder cancer stem cells, and could promote the proliferation, migration, and self-renewal capacity of bladder cancer stem cells. The high expression of keratin 6B contributes to improving the survival of bladder cancer patients.

ABSTRACT

Objective: To evaluate the impact of empagliflozin on peak oxygen uptake (VO2peak) in patients with heart failure with mildly reduced ejection fraction (HFmrEF). Methods: In this randomized controlled trial, consecutive HFmrEF patients admitted to the Department of Cardiology of China-Japan Friendship Hospital from September 2019 to October 2020 were screened, and randomly assigned to empagliflozin group (EG) or conventional group (CG) using a random number table. The enrolled patients were treated according to the guidelines, and patients in the empagliflozin group received additional empagliflozin (10 mg, once a day, orally) on top of the conventional treatment. The primary end points were VO2peak at 6 months after treatment, and the secondary end points included other parameters of cardiopulmonary exercise test (CPET), 6-minute walking distance, N-terminal B-type pro-natriuretic peptide (NT-proBNP) level, and Kansas City Cardiomyopathy Questionnaire (KCCQ) score. Results: A total of 112 patients were included (mean age 69 (57, 78) years, 84 male (75.0%)). There were 55 cases in CG group and 57 cases in EG group. There were no significant differences in baseline data including age, sex, body mass index, left ventricular ejection fraction, systolic blood pressure, heart rate, estimated glomerular filtration rate, glycosylated hemoglobin, hemoglobin, NT-proBNP, daily dose of tolasemi, combined medication, CPET parameters, the proportion of New York Heart Association heart function Ⅲ/Ⅳ, history of coronary heart disease, history of hypertension, history of diabetes (all P>0.05). At 6 months after treatment, VO2peak was significantly higher in EG group than in CG group(P=0.023). VE/VCO2 slope was significantly lower in EG group than in CG group(P=0.034). Oxygen uptake efficiency slope was significantly higher in EG group than in CG group(P=0.038). The level of NT-proBNP was significantly lower in EG group than in CG group(P=0.020). Six-minute walking distance was significantly higher in EG group than in CG group(P=0.037). KCCQ score was significantly higher in EG group than in CG group(P=0.048). Exercise oscillatory ventilation decreased in both groups (1 case in each group, P>0.05). Conclusion: Empagliflozin can significantly improve VO2peak in patients with HFmrEF.

ABSTRACT

Objective:To investigate the effects of different production processes on sensitization responses to human diploid cell rabies vaccines.Methods:This study randomly collected 360 serum samples in clinical trials of four rabies vaccines with different production processes. Total IgE levels at different time points were detected by ELISA. SPSS19.0 software was used for statistical analysis.Results:Total IgE test results showed that the seropositive rate was 20% (6/30) for all four vaccines. The lowest mean value of total IgE was 9 IU/ml and the highest was 210 IU/ml. Repeated measures analysis of variance showed that there was no significant difference in total IgE levels at different sampling time points ( P=0.284), and the total IgE level in people injected with multistep concentrated human diploid cell rabies vaccine was significantly below that in people immunized with Vero cell rabies vaccine ( P=0.024). Conclusions:Increasing the immune dosage of human rabies vaccine could not result in a rise in total IgE. Human diploid cell rabies vaccines had good safety as the production process could remove most of allergenic impurities.

ABSTRACT

Objective:To evaluate the independent prognostic value of minute ventilation/carbon dioxide production slope (VE/Vco 2 slope)on heart failure after acute myocardial infarction. Methods:131 patients with acute myocardial infarction (AMI) treated in the cardiology department of China-Japan Friendship Hospital from September 2018 to September 2019 were collected and followed up 3 months after discharge. They were divided into heart failure (HF) group and non-heart failure (NHF) group. All the patients underwent cardiopulmonary exercise test (CPET) before discharge.Results:Three months after discharge, the VE/Vco 2 slope was higher in HF group than in NHF group (36.7±3.8 vs 29.7±4.0, P=0.014). The best VE/Vco 2 slope cutoff for the prediction of heart failure after 3 month was 33.05 with a sensitivity of 81.4% and a specificity of 80.6% [area under curve (AUC) was 0.844, P<0.001]. VE /Vco 2 slope level was an independent predictor of heart failure in patients with acute myocardial infarction after discharge ( OR=1.245, 95% CI: 1.021-1.366, P=0.019). Other independent indicators related to heart failure included N-terminal pro-B type natriuretic peptid (NT-proBNP) level ( OR=1.283, 95% CI: 1.019-1.399, P=0.033). Conclusions:VE/Vco 2 slope yielded strong, independent predictive value for heart failure at 3 month after discharge to AMI patients.

ABSTRACT

Objective: To establish an intramedullary transplantation model of primary megakaryocytes to evaluate the platelet-producing capacity of megakaryocytes and explore the underlying regulatory mechanisms. Methods: Donor megakaryocytes from GFP-transgenic mice bone marrow were enriched by magnetic beads. The platelet-producing model was established by intramedullary injection to recipient mice that underwent half-lethal dose irradiation 1 week in advance. Donor-derived megakaryocytes and platelets were detected by immunofluorescence staining and flow cytometry. Results: The proportion of megakaryocytes in the enriched sample for transplantation was 40 to 50 times higher than that in conventional bone marrow. After intramedullary transplantation, donor-derived megakaryocytes successfully implanted in the medullary cavity of the recipient and produce platelets, which showed similar expression of surface markers and morphology to recipient-derived platelets. Conclusion: We successfully established an in vivo platelet-producing model of primary megakaryocytes using magnetic-bead enrichment and intramedullary injection, which objectively reflects the platelet-producing capacity of megakaryocytes in the bone marrow.

ABSTRACT

【Objective】 To study the influencing factors of blood source indicators related to coronary artery lesions in children with Kawasaki disease (KD). 【Methods】 Clinical data of children diagnosed with KD admitted to our hospital from January 1, 2015 to December 31, 2019 were retrospectively analyzed. Baseline data comparison and multivariate Logistic regression analysis were used to compare the differences in blood source indicators between the coronary artery lesion (CAL) group and the non-coronary artery lesion (nCAL) group, and the receiver operating characteristic (ROC) curve was drawn. 【Results】 There were significant differences in sex, erythrocyte sedimentation rate (ESR), lymphocyte count (L#) and red blood cell distribution width (RDW) between the CAL group and the nCAL group (P<0.05). Male, lower ESR, lower L#, and higher RDW were independent risk factors for CAL. OR values and their 95% confidence intervals (95% CI) were 0.279 (0.117, 0.669), 0.973 (0.955, 0.992), 0.675 (0.513, 0.889), and 2.433 (1.313, 4.506), respectively. The sensitivity and specificity of RDW for predicting CAL were 37.3% and 86.4%, the best cutoff value was 13.45%, the area under curve (AUC) was 0.616, and 95% CI was (0.514, 0.718) (P<0.05). ESR and L# had no predictive value for CAL. 【Conclusion】 Blood source indicators of children with Kawasaki disease, including blood routine and inflammatory indicators, especially RDW, have certain predictive value for coronary artery lesions. They can be combined with echocardiography to evaluate disease progression.

ABSTRACT

Natural products are valuable resources for discovering new drugs. So far, screening bioactive compounds from organism extracts is still an important and challenging task. Traditional biometric guided method involves repeated fractionation steps and bioactivity tests, which are time-consuming, labor-consuming, and inefficient. Ligand fishing is a bioanalysis method for screening ligands from complex organism extracts based on intermolecular affinity interactions. It has the characteristics of strong specificity, high efficiency, and less requirement for sample pretreatment. In this review, we summarize the classification of ligand fishing strategy and its application in enzyme inhibitors screening. Finally, the development prospects of this technology are forecasted.

ABSTRACT

A previous study has indicated that Krüppel-like factor 7 (KLF7), a transcription factor that stimulates Schwann cell (SC) proliferation and axonal regeneration after peripheral nerve injury, is a promising therapeutic transcription factor in nerve injury. We aimed to identify whether inhibition of microRNA-146b (miR-146b) affected SC proliferation, migration, and myelinated axon regeneration following sciatic nerve injury by regulating its direct target KLF7. SCs were transfected with miRNA lentivirus, miRNA inhibitor lentivirus, or KLF7 siRNA lentivirus in vitro. The expression of miR146b and KLF7, as well as SC proliferation and migration, were subsequently evaluated. In vivo, an acellular nerve allograft (ANA) followed by injection of GFP control vector or a lentiviral vector encoding an miR-146b inhibitor was used to assess the repair potential in a model of sciatic nerve gap. miR-146b directly targeted KLF7 by binding to the 3'-UTR, suppressing KLF7. Up-regulation of miR-146b and KLF7 knockdown significantly reduced the proliferation and migration of SCs, whereas silencing miR-146b resulted in increased proliferation and migration. KLF7 protein was localized in SCs in which miR-146b was expressed in vivo. Similarly, 4 weeks after the ANA, anti-miR-146b increased KLF7 and its target gene nerve growth factor cascade, promoting axonal outgrowth. Closer analysis revealed improved nerve conduction and sciatic function index score, and enhanced expression of neurofilaments, P0 (anti-peripheral myelin), and myelinated axon regeneration. Our findings provide new insight into the regulation of KLF7 by miR-146b during peripheral nerve regeneration and suggest a potential therapeutic strategy for peripheral nerve injury.

ABSTRACT

@#The core symptoms of Parkinson's disease include motor symptoms and non-motor symptoms. For the motor symptoms, the rehabilitation includes the basic training of joints, gait training, the training of core muscle group and posture balance, the training of oral, facial, neck muscle and pharyngeal reflex, the training of lip movement, vocalization, sound volume, rhythm and speed, and the training of deep breathing exercises and abdominal pressure. For the non-motor symptoms, the rehabilitation includes the training of memory, attention, problem solving ability, activities of daily living and others, psychotherapy, family support, social participation, and other comprehensive treatments combined with medicine.
