ABSTRACT

OBJECTIVE To provide reference for the clinically safe application of acalabrutinib by mining and analyzing the risk signals of adverse drug events (ADE). METHODS The acalabrutinib-induced ADE reports were extracted from the U.S. FDA adverse event reporting system using the OpenVigil 2.1 platform from November 1, 2017 to March 31, 2023. The reporting odds ratio (ROR) method and composite criteria method from the Medicines and Healthcare Products Regulatory Agency (MHRA) were used for detection of ADE signals. RESULTS There were 7 869 ADE reports of acalabrutinib as the primary suspect drug and 142 ADE positive signals were detected from them, involving 20 system organ classes, which was generally consistent with the ADE recorded in the drug instruction of acalabrutinib, mainly involving general disorders and administration site conditions, various inspection, blood and lymphatic system disorders, various neurological disorders and cardiac disorders. In addition, this study identified several new potential ADE signals that were not mentioned in the drug instruction, including sudden cardiac death, pulmonary toxicity, tumor lysis syndrome, pleural effusion, dyspepsia, gastroesophageal reflux disease, bone pain, decreased blood pressure, and abnormal blood sodium, etc. CONCLUSIONS When using acalabrutinib, in addition to paying attention to the ADE recorded in its instructions, the risk of serious ADE that may lead to death, such as sudden cardiac death and pulmonary toxicity, should also be evaluated to avoid or reduce the occurrence of ADE as much as possible.

ABSTRACT

Parkinson's disease (PD) is a common neurodegenerative disease characterized by motor symptoms, including bradykinesia, resting tremor, and progressive rigidity. More recently, non-motor symptoms of PD, such as pain, depression and anxiety, and autonomic dysfunction, have attracted increasing attention from scientists and clinicians. As one of non-motor symptoms, pain has high prevalence and early onset feature. Because the mechanism of PD-related pathological pain is unclear, the clinical therapy for treating PD-related pathological pain is very limited, with a focus on relieving the symptoms. This paper reviewed the clinical features, pathogenesis, and therapeutic strategies of PD-related pathological pain and discussed the mechanism of the chronicity of PD-related pathological pain, hoping to provide useful data for the study of drugs and clinical intervention for PD-related pathological pain.

ABSTRACT

AlM: To investigate the effect of C. sinensis extracts on HBx (Hepatitis B virus X protein) induced cell proliferation and extracellular matrix (ECM) accumulation and the underlying mechanism in cultured human mesangial cells (HMCs). METHODS: Human mesangial cells were stable transfected with pCMV-HBx to establish an HBx over-expression model, and a control group was transfected with an empty vector. Cell proliferation was determined by MTT assay and DNA synthesis assay. Western blotting was used to measure the expression of PI3K/Akt signaling pathway-related proteins and extracellular matrix. RESULTS: HBx transfection induced cell proliferation, matrix accumulation. HBx-transfected mesangial cells had increased activity of the PI3K/Akt pathways, and treatment with C. sinensis suppressed this effect. CONCLUSlON: C.sinensis attenuates the HBx-induced human mesangial cell proliferation and matrix production in human mesangial cells via inhibition of the PI3K/Akt pathways.

ABSTRACT

【Objective】 To investigate the effect and mechanism of arctigenin (ARG) on hypoxia-reoxygenation (H/R) induced pyroptosis of cardiomyocytes. 【Methods】 H9C2 cells were cultured in vitro, and underwent hypoxia for 2 hours and reoxygenation for 4 hours to establish H/R cell injury model. The cells were divided into control group (Control), model group (H/R), ARG group, miR-21 simulation group (miR-21 mimic), and ARG+miR-21 inhibitor group (ARG+miR-21 inhibitor). TUNEL staining was used to detect the pyroptosis index of H9C2 cells; the lactate dehydrogenase (LDH) kit was used to detect the release of LDH in each group of cells; the enzyme-linked immunosorbent assay (ELISA) was used to detect the content of interleukin-1β (IL-1β) and interleukin-18 (IL-18). Western blotting was used to detect the expressions of pyroptosis-related proteins (Caspase-1, GSDMD, IL-1β and IL-18) in each group. 【Results】 Compared with those in the control group, the pyroptosis index, the release of LDH, IL-1β and IL-18, and the protein expressions of Caspase-1p20, GSDMD-N, IL-1β and IL-18 in the H/R group were significantly increased (P<0.01). Compared with H/R group, ARG group and miR-21 mimic group had significantly reduced pyroptosis index, LDH, IL-1β and IL-18 release, and protein expressions of Caspase-1 p20, GSDMD-N, IL-1β and IL-18 (P<0.01), and the above-mentioned index changes could be reversed after treatment with +miR-21 inhibitor. 【Conclusion】 ARG can inhibit H/R-induced pyroptosis of cardiomyocytes, and its mechanism is related to the promotion of miR-21 expression.

ABSTRACT

To investigate the carbapenemases distribution of carbapenem-resistant Klebsiella pneumoniae (CRKP) in the intensive care unit, and the clinical characteristics between carbapenem-resistant hypervirulent Klebsiella pneumoniae (CR-hvKP) and carbapenem-resistant non-hypervirulent Klebsiella pneumoniae (CR-non-hvKP) were compared. A total of 53 non-repetitive CRKP strains isolated from 49 patients in the intensive care unit of the Second Affiliated Hospital of Xi'an Jiaotong University from May 2020 to March 2021 were retrospectively studied. The carbapenemase inhibitor enhancement test was used for screening carbapenemase-producing strains, and the string test was carried out to screen the hypermucoviscosity phenotype. Using PCR to detect five main carbapenemase genes (blaKPC-2, blaNDM, blaIMP , blaVIM and blaOXA-48-like), common serotype (K1 and K2) and virulence gene (rmpA and iutA). Treated the strains with both rmpA and iutA genes as hypervirulent Klebsiella pneumonia (hvKP), and the whole genome sequencing of CR-hvKP was completed. At the same time, the clinical data of 49 patients were sorted out, and the differences in clinical characteristics of CR-hvKP and CR-non-hvKP infected patients were compared using the independent sample t test, Mann-Whitney U test, chi-square test or Fisher's exact probability test. CRKP isolated from the intensive care unit were extensively drug resistance and still had a good sensitivity to polymyxin B and tigecycline. Producing carbapenemases were the main resistance mechanism of CRKP (52/53, 98.1%). Of the 53 CRKP strains, except for 1strain that did not detect carbapenemase, at least one carbapenemase resistance gene was detected in the remaining 52 CRKP strains, of which 45 strains carried an enzyme, including 36 blaKPC-2 (36/53, 67.9%), 8 blaNDM (8/53, 15.1%), 1 blaIMP (1/53, 1.9%), and 7 strains carried with both blaKPC-2 and blaNDM (7/53, 13.2%). String test and virulence gene showed that 7 CR-hvKP strains (13.2%) were detected in 53 CRKP strains, and two of which were hypermucoviscosity phenotype. Sequencing results revealed that CR-hvKP were mainly ST11 type. Almost all patients with CR-hvKP infection were over 60 years old (7/7), with invasive treatment (7/7), pulmonary infection with hypermucoviscosity phenotype (2/7) and high mortality (5/7); and the percentage of neutrophils in patients with CR-hvKP infection (86.44±4.70) % was higher than those patients with CR-non-hvKP infection (78.90±19.15) %, the difference was statistically significant (t=-2.225, P=0.032). The CR-hvKP strains in the intensive care unit mainly produced KPC-2 enzyme, with K2 capsular serotype and ST11 type. It is necessary to strengthen the monitoring and control of the CR-hvKP strain to prevent the co-evolution of drug-resistant and hypervirulent strains.

ABSTRACT

Objective:To explore the application of new teaching techniques and establish a new model for experimental teaching of Medical Statistics for undergraduate students of clinical medicine. Methods:We enrolled 2 classes of students from Xi'an Medical University as research objects, and they were randomized into study group ( n=62) and control group ( n=54). The study group received "traditional demonstration+ blended" learning, while the control group only received traditional teaching. On the premise of balanced comparability, the effects of the two teaching patterns were evaluated from such three aspects as satisfaction questionnaire, teacher's self-evaluation and achievement. SPSS 22.0 was performed for chi-square test, t test and rank sum test. Results:At the end of the semester, the value cognition of statistics in both groups was higher than before class, and the study group [93.5% (58/62)] was higher than that in the control group [68.5% (37/54)] ( χ2=12.20, P<0.001). The overall satisfaction ( Z=-7.05, P<0.001) and the satisfaction with teaching methods ( Z=-3.95, P<0.001) of the study group were significantly higher than those of the control group, with no statistical difference in satisfaction with teaching contents between the two groups ( Z=-0.27, P=0.784). More students in the study group thought that the experimental class deepened their understanding of statistical theory ( χ2=26.87, P<0.001). In the last four experimental classes, the post-test scores of both groups were higher than those of the pre-test, but the pre-test scores and post-test scores of the study group were higher than those of the control group. The performance of software operation in study group was higher than that in control group ( t=8.27 P<0.001). There was no statistical difference in the final test scores between the two groups ( t=0.29, P=0.773). Conclusion:The "traditional demonstration+ blended" learning is more in line with the students' learning pattern, and can better improve students' cognition and satisfaction of the statistics, especially can better cultivate students' team cooperation, expression and the SPSS analysis ability.

ABSTRACT

To explore the mechanism of Hedyotis Diffusae Herba-Smilacis Glabrae Rhizoma(HDH-SGR) in treating lung adenocarcinoma based on big data bioinformatics combined with network pharmacology analysis and molecular docking technology. The chemical components and potential therapeutic targets of HDH-SGR were obtained from Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP). Lung adenocarcinoma-related genes were obtained from The Cancer Genome Atlas(TCGA), Therapeutic Target Database(TTD), Pharmacogenetics and Pharmacogenomics Knowledge Base(PharmGKB), Online Mendelian Inheritance in Man(OMIM), DrugBank, and GeneCards. "Drug component-target" network was constructed using Cytoscape to screen out key compounds. STRING was used to build protein-protein interaction(PPI) network and core targets were screened out by Cytoscape-CytoNCA topology analysis. Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) analyses of target genes were performed by R-clusterProfiler. Finally, key compounds were docked to core target genes using AutoDock. The results showed that 22 active compounds and 499 potential therapeutic targets were obtained from HDH-SGR. A total of 14 332 lung adenocarcinoma-related targets were screened out through six data platforms, including 182 common targets. Fifteen core targets were screened out from the PPI network. GO and KEGG analyses revealed significant enrichment of relevant target genes in various biological processes, cellular functions(e.g., response to lipopolysaccharide, nuclear receptor activity, and ligand-activated transcription factor activity) and close relationship between target genes and non-small cell lung cancer signaling pathways. Based on the results of molecular docking validation, diosgenin, quercetin, naringenin, taxifolin, 2-methoxy-3-methyl-9,10-anthraquinone, stigmasterol, and β-sitosterol were able to bind tightly to the core targets. HDH-SGR can intervene in lung adenocarcinoma through multiple targets and signaling pathways, such as non-small cell lung cancer signaling pathways. The binding of active components in Chinese medicine to key targets is presumedly one of the mechanisms that produce therapeutic effects.

ABSTRACT

OBJECTIVE@#To detect the ectodysplasin A (EDA) gene mutation in patients with hypohidro-tic ectodermal dysplasia (HED), and to analyze the distribution pattern of missing permanent teeth and the systemic manifestation of HED patients with EDA gene mutation.@*METHODS@#Twelve HED families were enrolled from clinic for genetic history collection, systemic physical examination and oral examination. Peripheral blood or saliva samples were collected from the probands and the family members to extract genomic DNA. PCR amplification and Sanger sequencing were utilized to detect the EDA gene variations, which were compared with the normal sequence (NM_001399.5). The functional impact of EDA gene variants was then evaluated by functional prediction of mutation, conservation analysis and protein structure prediction. The pathogenicity of each EDA gene variation was assessed according to the stan-dards and guidelines of the American College of Medical Genetics and Genomics (ACMG). The systemic phenotype and missing permanent tooth sites of HED patients with EDA gene mutations were summarized, and the missing rate of each tooth position was analyzed and compared.@*RESULTS@#Eight out of twelve HED families were identified to carry EDA gene mutations, including: c.164T>C(p.Leu55Pro); c.457C>T (p.Arg153Cys); c.466C>T(p.Arg156Cys); c. 584G>A(p.Gly195Glu); c.619delG(p.Gly207Profs*73); c.673C>T(p.Pro225Ser); c.676C>T(p.Gln226*) and c.905T>G(p.Phe302Cys). Among them, c.164T>C(p.Leu55Pro); c.619delG(p.Gly207Profs*73); c.673C>T(p.Pro225Ser); c.676C>T(p.Gln226*) and c.905T>G(p.Phe302Cys) were novel mutations. The HED patients with EDA gene mutations in this study were all male. Our results showed that the average number of missing permanent teeth was 13.86±4.49, the average number of missing permanent teeth in the upper jaw was 13.14±5.76, the missing rate was 73.02%. And in the lower jaw, the average number of missing permanent teeth was 14.57±3.05, the missing rate was 80.95%. There was no significant difference in the number of missing teeth between the left and right sides of the permanent dentition (P>0.05). Specifi-cally, the maxillary lateral incisors, the maxillary second premolars and the mandibular lateral incisors were more likely to be missing, while the maxillary central incisors, the maxillary and mandibular first molars had higher possibility of persistence.@*CONCLUSION@#This study detected novel EDA gene pathogenic variants and summarized the distribution pattern of missing permanent teeth of HED patients, thus enriched the variation and phenotype spectrum of EDA gene, and provided new clinical evidence for genetic diagnosis and prenatal consultation.

ABSTRACT

Objective:To investigate the effect of Clostridium perfringens combined with live bacteria therapy on intestinal flora, inflammation and immune indicators in children with pneumonia and antibiotic associated diarrhea.Methods:From December 2016 to October 2019, 44 neonates with pneumonia and antibiotic associated diarrhea diagnosed and treated in the Sixth People's Hospital of Datong were selected in the study, and they were divided into control group and observation group according to the random number table method, with 22 cases in each group.On the basis of routine symptomatic treatment, the control group was treated by oral administration of Saccharomyces boulardii, and the observation group was treated with Clostridium perfringens combined with live bacteria powder.The treatment course was two weeks.The intestinal flora, inflammatory factors and immune function of the two groups were compared.Results:There were no statistically significant differences in the levels of IL-2, IL-6 and TNF-α between the two groups before treatment(all P>0.05), and the levels of IL-2, IL-6 and TNF-α in the two groups after treatment were significantly improved(all P<0.05). The levels of IL-2[(34.20±8.55)ng/L vs.(40.13±10.32)ng/L], IL-6[(21.02±5.66)ng/L vs.(31.25±7.82)ng/L] and TNF-α[(30.10±6.20)ng/L vs.(43.55±9.52)ng/L] in the observation group were significantly lower than those in the control group( t=7.501, 6.885, 8.264, all P<0.05). There were no statistically significant differences in the number of Lactobacillus, Bifidobacterium and Eubacterium in the two groups before treatmentt(all P>0.05), and the number of Lactobacillus, Bifidobacterium and Eubacterium in the two groups after treatment increased significantly(all P<0.05). The number of Lactobacillus[(9.50±0.53)×10 8 CFU/mL vs.(8.95±0.44)×10 8 CFU/mL], Bifidobacterium[(10.60±0.53)×10 8 CFU/mL vs.(9.90±0.46)×10 8 CFU/mL] and Eubacterium[(8.93±0.68)×10 8 CFU/mL vs.(8.08±0.40)×10 8 CFU/mL] in the observation group were significantly higher than those in the control group( t=5.065, 6.547, 5.116, all P<0.05). There were no statistically significant differences in the levels of CD 3+ , CD 4+ , CD 8+ and CD 4+ /CD 8+ between the two groups before treatment(all P>0.05), and the levels of CD 3+ , CD 4+ , CD 8+ and CD 4+ /CD 8+ in the two groups after treatment were significantly improved(all P<0.05). The levels of CD 3+ [(62.55±5.06)% vs.(57.12±4.39)%], CD 4+ [(40.52±3.52)% vs.(36.43±2.55)%], CD 4+ /CD 8+ [(1.78±0.22) vs.(1.43±0.13)] in the observation group were significantly higher than those in the control group( t=7.504, 6.958, 5.452, all P<0.05). The level of CD 8+ [(21.22±2.05)% vs.(25.44±2.49)%] in the observation group was significantly lower than that in the control group( t=5.112, P<0.05). Conclusion:Clostridium perfringens combined with live bacteria in the treatment of neonatal pneumonia with antibiotic associated diarrhea can improve intestinal flora, reduce inflammatory response and improve immune function, and the effect is better.

ABSTRACT

Objective To explore the causes, diagnosis and treatment of biliary tract hemorrhage after hepatic cancer thermal ablation. Methods The clinical data of 6 patients with biliary tract hemorrhage developed after hepatic cancer thermal ablation in our hospital from May 2013 to May 2018 were retrospectively analyzed. Endoscopic or digital subtraction angiography (DSA) was used to determine the bleeding points. After a definite diagnosis of biliary tract hemorrhage, selective hepatic artery embolization was performed. Hemoglobin, hepatic function and other indicators were detected after surgery to evaluate the treatment effect. Results Preoperative imaging diagnosis showed that 3 patients had mild dilatation of the intrahepatic bile duct. Endoscopy examination showed that there was persistent bleeding in the duodenal papilla with blood clot formation in all 6 patients. DSA examination showed that there were clear bleeding points in 4 patients, and no bleeding points in 2 patients. After embolization, the patients complained of biliary colic disappearance. Within 24 h after embolization, the patients still had hematochezia but the hemoglobin levels were stable. After 24 h operation, the hematochezia gradually disappeared. After selective hepatic artery embolization treatment, 6 patients obtained good hemostatic effects with the effective rate being 100%. All patients were discharged. No biliary bleeding reoccured in the 6-month follow-up. Conclusion Local expansion of intrahepatic bile duct is one of the main risk factors of biliary tract hemorrhage after hepatic cancer ablation. Triad of biliary bleeding is a typical symptom. Endoscopic detection rate is high. DSA examination diagnosis still need to be supported by clinical symptoms. Selective hepatic artery embolization is an effective treatment method. Selective hepatic artery embolization is also satisfactory in diagnostic treatment of patients without bleeding points on DSA examination.

ABSTRACT

Objective To investigate a suitable model for the teaching of medical statistics in postgraduates in general medicine. Methods A total of 225 postgraduates who majored in general medicine in the class of 2017 in Xi'an Medical College were enrolled and randomly divided into study group with 130 postgraduates and control group with 95 postgraduates. The postgraduates in the study group received blending learning (with the application of Wenjuanxing and Duifenyi), and those in the control group received traditional teaching. The two groups were compared in terms of teaching efficiency and degree of satisfaction. Results Compared with the control group, the study group had significantly higher score of objective questions (t=11.2, P<0.01), score of SPSS analysis (t=5.44, P<0.01), total score of exams (t=26.3, P<0.01), and degree of satisfaction (Z=-3.853, P<0.01). Conclusion Blending learning may have a better overall effect than traditional teaching and can help students to achieve stronger abilities of data analysis and SPSS operation. This is an important attempt to change the teaching mode of medical statistics in postgraduates and provides a feasible method for the training of general medical talents with innovative and scientific thinking.

ABSTRACT

The study is aimed to clarify the spatial distribution of Epimedium koreanum( Ek) high-quality production areas. Through visiting and field investigation,collecting the distribution information of Ek samples,and based on the four kinds of flavonoids in Ek,the high-quality production areas and distribution of Ek distribution of the main environmental factors were drawn using GIS technology,the maximum entropy model( MaxEnt),geographical detector statistical analysis method,and the statistical significance of regression equation were obtained. Considering the content of 4 main flavonoids in Ek,the results of this study showed that the main environmental factors,such as precipitation,annual precipitation variation coefficient,annual average temperature and clay content exhibited the greatest influence on the growth suitability of Ek. Ek materials quality concentrated distribution in southeastern Jilin province Changbai mountain hinterland and northeastern Liaoning province. Ek with high content of epimedine A and epimedine C are mainly distributed in the southeastern Jilin province and northeastern Liaoning province,Ek with high epimedine B is distributed in eastern Liaoning province; high icariin Ek was found in most area of northeastern Liaoning province,a small amount distributed in the southeast of Jilin province. This study predicted the climate suitability distribution of Ek,and provided reference for the rational planning and establishment of the standardized cultivation base of Ek.

ABSTRACT

OBJECTIVE@#This study aims to compare the osteogenic differentiation capability of stem cells derived from human inflammatory periodontal ligament tissues (iPDLSCs) with those of stem cells derived from healthy periodontal ligament tissues (hPDLSCs). Both types of tissues were induced by stromal cell derived factor (SDF-1) in vitro.@*METHODS@#iPDLSCs and hPDLSCs were primarily cultured by tissue digestion method and purified by limited dilution cloning. The cells were passaged and identified by stem cell surface marker expression through flow cytometry. Then, we used thiazolyl blue tetrazolium bromide to detect and compare the proliferation capabilities of the iPDLSCs and hPDLSCs. Express of bone volumes were detected by alizarin red staining after SDF-1 was added to the cells. Using alkaline phosphatase, we evaluated the osteogenic differentiation capability of the cells induced by SDF-1. The expression levels of the osteogenesis-related genes of the cells induced by SDF-1 were determined by reverse transcription-polymerase chain reaction.@*RESULTS@#After purification, both iPDLSCs and hPDLSCs expressed stem cell markers. hPDLCSs had a higher proliferation capability than iPDLSCs. Osteogenesis-related genes had higher expression levels in the cells induced by SDF-1 than in those without induction (P<0.05). SDF-1 at 50 and 200 ng·mL⁻¹ concentration greatly affected the differen-tiation capabilities of iPDLSCs and hPDLSCs respectively.@*CONCLUSIONS@#iPDLSCs and hPDLSCs had osteogenic differentia-tion capability. The level of osteogenic differentiation in normal and inflamed periodontal ligament stem cells increases after SDF-1 induction.
