RESUMO

OBJECTIVE To investigate the mechanism of catalpol affecting the differentiation of helper T cell 17 (Th17) by interfering the expressions of pyruvate kinase M2 (PKM2) and lactate dehydrogenase A (LDHA). METHODS The naive CD4+ T cells were selected from the spleen of C57BL/6 mice, and were differentiated into Th17 cells by adding directional differentiation stimulants for 72 hours. At the same time, the cells were treated with 0 (directed control), 20, 40 and 80 μg/mL catalpol. The flow cytometry was used to detect the proportion of Th17 cell differentiation in cells; the colorimetric method was adopted to detect the levels of pyruvate and lactate in cell culture supernatant; mRNA expressions of retinoid-related orphan nuclear receptor gamma t (RORγt), PKM2 and LDHA were detected by qRT-PCR method; Western blot was used to detect the expression levels of PKM2, LDHA, signal transducer and activator of transcription 3 (STAT3), and phosphorylated STAT3 (p-STAT3) proteins in cells. RESULTS Compared with the directed control group, after 72 hours of treatment with 20, 40, 80 μg/mL catalpol, the differentiation ratio of Th17 cells were decreased by 6.74%, 8.41%, 9.24%, and the levels of pyruvate and lactate in the cell culture supernatant, the mRNA expressions of PKM2, LDHA and RORγt as well as the protein expressions of PKM2 and LDHA and the phosphorylation of STAT3 were significantly reduced (P<0.05). CONCLUSIONS Catalpol can reduce the glycolysis level by down-regulating the expressions of PKM2 and LDHA, thereby inhibiting the differentiation of Th17 cells.

RESUMO

Xanthine oxidoreductase (XOR), the key enzyme catalyzing purine to produce uric acid, including two subtypes, xanthine dehydrogenase (XDH) and xanthine oxidase (XO), respectively, in vivo. Usually, XDH and XO can transform to each other. In this study, based on the principle that the subtype XO or XDH uses different electron acceptors, the methods for the measuring the activities of bovine milk XOR (pure enzyme) and its subtypes were established. The optimal concentrations of substrate xanthine (50 μmol·L-1) and electron acceptor NAD+ (50 μmol·L-1), pH value (7.80) were investigated. The ranges of the XOR, XO, XDH activity which could be determined were 0.97-17.5 U·L-1, 1-9 U·L-1, and 66-1 191 mU·L-1, respectively. Furthermore, the methods for determining the activities of XOR and its subtypes in mouse liver were established. The preparation of liver samples, the optimal concentrations of xanthine (100 μmol·L-1) and NAD+ (100 μmol·L-1) were researched. And the activity ranges of XOR, XO and XDH in mouse liver which could be determined were 0.67-3.98, 0.19-1.08, and 0.52-3.55 U·gprot-1, respectively. With the methods above, the effects of classic XOR inhibitor allopurinal (Allo) on XOR, XO and XDH from both milk and mouse liver were determined. All animal experiments have been approved by the Animal Experimental Center, Institute of Materia Medica, Chinese Academy of Medical Science and Peking Union Medical College (00003346). This study established new methods for the determination of XOR and its subtypes activity in pure enzyme system and in mouse liver, respectively, which were accurate and convenient. It laid the experimental foundation for exploring the different pathophysiological effects of XOR in the body and developing new XOR inhibitors.

RESUMO

ObjectiveTo explore the role of efficacy evaluation methods in providing evidence for traditional Chinese medicine (TCM) clinical practice guidelines based on a demonstration study of clinical efficacy evaluation of TCM for allergic rhinitis (AR),aiming to enrich the sources of evidence for guideline development. MethodReal-world data of TCM medication for AR were collected and efficacy evaluation was carried out. SPSS 16.0 software was used to calculate the conformity of clinical syndromes,main prescriptions, and medications to the guidelines. Correlation analysis of efficacy and medications was performed according to guideline conformity to compare the differences in medications between real-world clinical applications and current guidelines. ResultA total of 198 cases were collected and the clinical medications were compared with the relevant guidelines for AR. It was found that the clinical syndrome conformity was above 70%,and in addition to the guideline syndrome,there were also syndromes in six meridians and other mixed syndromes in clinical practice. The guideline conformity of the main prescriptions used in clinical practice showed a positive correlation trend with efficacy. There were some differences between the commonly used drugs in clinical practice and those recommended by the guidelines. For example,for lung Qi deficiency and cold syndrome,drugs such as Angelicae Dahuricae Radix, Magnoliae Flos, and Schisandrae Chinensis Fructus were often used. For kidney Yang deficiency syndrome,drugs such as Atractylodis Macrocephalae Rhizoma and Ostreae Concha were often used. For spleen Qi deficiency and weakness syndrome,drugs such as Poria, Cinnamomi Ramulus, and Magnoliae Flos were used. For lung Qi deficiency and cold syndrome in children,drugs such as Chebulae Fructus, Cicadae Periostracum, Zingiberis Rhizoma, and Ginseng Radix et Rhizoma were used. For lung and spleen Qi deficiency syndrome,drugs such as Dioscoreae Rhizoma, Menthae Haplocalycis Herba, Amomi Fructus, and Zingiberis Rhizoma were used. There were also some differences in the commonly used drugs for adults and children. For example,for lung Qi deficiency and cold syndrome,adults often used Angelicae Dahuricae Radix, Magnoliae Flos, and Tribuli Fructus,while children often used Ginseng Radix et Rhizoma, Paeoniae Radix Alba, and Poria. For lung meridian hidden heat syndrome, adults often used Bupleuri Radix, Asari Radix et Rhizoma, Pinelliae Rhizoma, and Xanthii Fructus, while children often used Houttuyniae Herba, Menthae Haplocalycis Herba, Citri Reticulatae Pericarpium, and Massa Medicata Fermentata. ConclusionEffective medication regimens can be screened out based on efficacy evaluation methods,which can help supplement immediate, objective, and clinically relevant evidence of medication for the development of clinical practice guidelines in TCM from the perspective of clinical effectiveness.

RESUMO

Amid the modernization and internationalization of traditional Chinese medicine(TCM), the safety of TCM has attracted much attention. At the moment, the government, scientific research teams, and pharmaceutical enterprises have made great efforts to explore methods and techniques for clinical safety evaluation of TCM. Although considerable achievements have been made, there are still many problems, such as the non-standard terms of adverse reactions of TCM, unclear evaluation indicators, unreasonable judgment methods, lack of evaluation models, out-of-date evaluation standards, and unsound reporting systems. Therefore, it is urgent to further deepen the research mode and method of clinical safety evaluation of TCM. Based on the current national requirements for the life-cycle management of drugs, this study focused on the problems in the five dimensions of clinical safety evaluation of TCM, including normative terms, evaluation modes, judgment methods, evaluation standards, and reporting systems, and proposed suggestions on the development of a life-cycle clinical safety evaluation method that conformed to the characteristics of TCM, hoping to provide a reference for future research.

RESUMO

Clinical efficacy is the basis for the development of traditional Chinese medicine(TCM), and the evaluation of clinical efficacy of TCM has always been the focus of attention. The technical and methodological difficulties in the evaluation process often restrict the generation of high-level evidence. Therefore, methodological research should be deepened and innovative practice should be carried out to study the application of scientific research methods in the evaluation of the advantages of TCM. After more than ten years of development, the clinical efficacy evaluation of TCM, on the basis of the initially classic placebo randomized controlled trials, has successively carried out a series of meaningful attempts and explorations in N-of-1 trials, cohort studies, case-control studies, cross-sectional studies, real world studies, narrative medicine studies, systematic evaluation, and other aspects, laying the foundation for the transformation of TCM from "experience" to "evidence". This paper focused on the clinical efficacy evaluation of TCM, summarized the main connotation and development status of efficacy evaluation indicators, standards, and methods, and put forward corresponding countermeasures and suggestions for the problems of indicator selection, standard formulation, and methodology optimization in the research process. It is clear that scientific and objective evaluation of the efficacy of TCM is an urgent problem to be solved at present.

RESUMO

Polyurethane (PUR) plastics is widely used because of its unique physical and chemical properties. However, unreasonable disposal of the vast amount of used PUR plastics has caused serious environmental pollution. The efficient degradation and utilization of used PUR plastics by means of microorganisms has become one of the current research hotspots, and efficient PUR degrading microbes are the key to the biological treatment of PUR plastics. In this study, an Impranil DLN-degrading bacteria G-11 was isolated from used PUR plastic samples collected from landfill, and its PUR-degrading characteristics were studied. Strain G-11 was identified as Amycolatopsis sp. through 16S rRNA gene sequence alignment. PUR degradation experiment showed that the weight loss rate of the commercial PUR plastics upon treatment of strain G-11 was 4.67%. Scanning electron microscope (SEM) showed that the surface structure of G-11-treated PUR plastics was destroyed with an eroded morphology. Contact angle and thermogravimetry analysis (TGA) showed that the hydrophilicity of PUR plastics increased along with decreased thermal stability upon treatment by strain G-11, which were consistent with the weight loss and morphological observation. These results indicated that strain G-11 isolated from landfill has potential application in biodegradation of waste PUR plastics.

RESUMO

OBJECTIVE@#To evaluate the antidiarrheal effect of ethanol extract of Glycyrrhiza uralensis Fisch root (GFR) in vivo and jejunal contraction in vitro.@*METHODS@#In vivo, 50 mice were divided into negative control, positive control (verapamil), low-, medium- and high-dose GFR (250, 500, 1,000 mg/kg) groups by a random number table, 10 mice in each group. The antidiarrheal activity was evaluated in castor oil-induced diarrhea mice model by evacuation index (EI). In vitro, the effects of GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) on the spontaneous contraction of isolated smooth muscle of rabbit jejunum and contraction of pretreated by Acetylcholine (ACh, 10 µmol/L) and KCl (60 mmol/L) were observed for 200 s. In addition, CaCl2 was accumulated to further study its mechanism after pretreating jejunal smooth muscle with GFR (1 and 3 g/L) or verapamil (0.03 and 0.1 µmol/L) in a Ca2+-free-high-K+ solution containing ethylene diamine tetraacetic acid (EDTA).@*RESULTS@#GFR (500 and 1,000 mg/kg) significantly reduced EI in castor oil-induced diarrhea model mice (P<0.01). Meanwhile, GFR (0.01, 0.03, 0.1, 0.3, 1, 3, and 10 g/L) inhibited the spontaneous contraction of rabbit jejunum (P<0.05 or P<0.01). Contraction of jejunums samples pretreated by ACh and KCl with 50% effective concentration (EC50) values was 1.05 (0.71-1.24), 0.34 (0.29-0.41) and 0.15 (0.11-0.20) g/L, respectively. In addition, GFR moved the concentration-effect curve of CaCl2 down to the right, showing a similar effect to verapamil.@*CONCLUSIONS@#GFR can effectively against diarrhea and inhibit intestinal contraction, and these antidiarrheal effects may be based on blocking L-type Ca2+ channels and muscarinic receptors.

RESUMO

Objective:To evaluate the effect of urinary albumin creatinine ratio (UACR) on diabetic retinopathy (DR) in patients with type 2 diabetes. Receiver operating characteristic (ROC) curve was applied to find the cut-off value of UACR for diagnosing DR.Methods:A prospective cohort study of 2 490 patients with type 2 diabetes was conducted with a mean follow-up of 7 years ranging from 3 to 10 years. Dilated fundus examination was performed once a year, and patient history and clinical data were collected and analyzed. Patients were divided into three groups according to the UACR: Q1, normal urinary albumin group (UACR<30 mg/g), Q2, microalbuminuria group (30 mg/g≤UACR≤299 mg/g), and Q3, macroalbuminuria group (UACR>300 mg/g), respectively. Cox regression analysis was used to explore the influence of UACR and other factors on DR, and ROC curve was drawn to evaluate the value of UACR in diagnosis of DR.Results:Cox regression analysis showed that UACR was the risk factor of DR( HR=1.108, 95% CI 1.023-1.241, P<0.001). It showed that the patients in Q3 group had the highest risk of proliferative DR ( HR=3.128, 95% CI 2.025-4.831, P<0.001), the patients in Q2 group followed( HR=1.918, 95% CI 1.355-2.714, P<0.001), and the patients in Q1 group were the lowest. ROC curve analysis showed that area under UACR curve was 0.746(95% CI 0.681-0.812, P<0.001), and the cut-off value, sensitivity, and specificity for the diagnosis of PDR were 54.12mg/g, 0.769, and 0.653, respectively. Conclusion:The UACR can predict the progression of PDR in type 2 diabetes patients, therefore it may be used as a preliminary predictor for the progression of DR.

RESUMO

【Objective】 To compare the effectiveness of the old mode of blood isolation and batch release (the old mode) and the new mode in Chengdu, so as to provide basis for optimizing working strategy. 【Methods】 1) The blood testing report was released one by one in the old mode but released uniformly in accordance with the blood batches classified by blood storage and supply department in the new mode. 2) In the old mode, apheresis platelet samples were detected by serological testing first and nucleic acid testing(NAT) later, and whole blood samples were reasonably arranged according to blood inventory and detection workload. In the new mode, platelets samples collected within our center headquarters were detected by serological test and NAT simultaneously, while those collected outside the center complied with the old strategy. As for whole blood, the same batch samples classified by blood storage and supply department should be arranged to the detection line with the fewest samples.3) The turnaround time(TAT) in the laboratory (referred to as sample TAT) and the TAT in the blood to-detect stock (referred to as blood TAT) in two phases(year 2016 vs 2018, pre- and post- the new mode), involving 164 748 and 179 488 blood samples, were compared by SPSS25.0 software. The constituent ratio of the TATs were compared with Chi-square test, and the difference of blood TAT between old and new mode were compared with Mann-Whitney U test. 【Results】 1) Significant difference was noticed in constituent ratio of TATs between old and new mode (P<0.05). 2)The blood TATof apheresis platelets using the new mode was 0.95(QR: 0.22)days, with the median 0.20 days shorter than that the old mode.. The blood TAT of whole blood in the new mode was 3.77 (QR: 1.99) days, with the median 0.90 days shorter than that in the old mode, and the difference was statistically significant (P<0.05). 【Conclusion】 Compared with the old mode, the new mode showed the following advantages: 1) It can realize the unified issuing of testing reports of blood with the same batch, contribute to the early discovery of errors that occurred during blood donation process, and located the errors wihin intra-batches for investigation. 2) It can advance the issuing of blood testing reports of the same batch. 3) It can make the flow of samples and blood with the same batch between different departments more standardized and orderly, and optimize the process of blood sorting thus shortening blood TAT. 4) It can realize the counting and checking of samples, within the same batch, at different states, so as to minimize the error issuing of unqualified blood and to-detect blood, and is more conducive to ensure the quality, safety and timely supply of blood.

RESUMO

Objective:To investigate the molecular genetic and clinical characteristics of MEF2D-BCL9 fusion gene-positive acute B-cell lymphoblastic leukemia (B-ALL), and to provide the reference for the diagnosis and treatment of the disease.Methods:The medical record and experimental examination data of a 18-year-old female MEF2D-BCL9 fusion gene-positive B-ALL patient were retrospectively analyzed. The clinical manifestations and biological characteristics of MEF2D-BCL9 fusion gene-positive B-ALL were summarized.Results:This 18-year-old female patient was treated in a local hospital in December 2018 and was diagnosed as B-ALL. She achieved complete remission after chemotherapy and recurred at 6 months after the initial onset, and then she was admitted to Hebei Yanda Ludaopei Hospital in the 9 months after the initial onset.MEF2D-BCL9 fusion gene was detected through RNA-sequencing (RNA-seq) and verified by using polymerase chain reaction and Sanger sequencing. Bone marrow cell morphology was similar to mature B cells with vacuoles but without characteristic chromosome karyotype abnormalities. The patient achieved remission after VLD regimen chemotherapy, chimeric antigen receptor T-cell (CAR-T) therapy and bridged to allogeneic hematopoietic stem cell transplantation (allo-HSCT). She has maintained complete remission for 2 years at the last follow-up in February 2022.Conclusions:MEF2D-BCL9 fusion gene-positive B-ALL is characterized with high risk, early relapse and poor prognosis. These patients may benefit from CAR-T and allo-HSCT. It further emphasizes the importance of taking MEF2D-BCL9 fusion gene into the detection or identification by using RNA-seq, particularly for those newly diagnosed B-ALL patients in children and adolescents with specific bone marrow morphology.

RESUMO

As food preferences and eating habits form early in life, the development of healthy eating habits in early childhood is a way to prevent diet-related diseases. The dietary pattern approach examines the effect of an overall diet on health outcomes, instead of individual foods or nutrients, thereby presenting a comprehensive evaluation of children's dietary intake. This article reviews the current literature to summarize the main methods for assessing dietary patterns and explore relationships between children's dietary patterns and obesity, puberty onset, cardiovascular diseases, and neurodevelopment. The purpose of this review is to provide evidence-based support for reducing the risk of diet-related diseases in children and recommendations for future research directions.

RESUMO

Circular RNA (circRNA) is a new group of endogenous non-coding RNAs produced by back-splicing, which has multiple molecular functions such as acting as microRNA sponges, regulators of transcription and splicing, adaptors for protein-protein interaction. Recent studies have shown that circRNA play an essential role in development and progression of retinal microvascular dysfunction, diabetic retinopathy, age-related macular degeneration, proliferative vitreoretinopathy, eye diseases caused by hyperhomocysteine and ocular malignancy. In pathological conditions, the differential expression of circRNA alters the transcription and translation of corresponding genes, thus changing the activity and function of cells. CircRNA may become a new marker and prognostic indicator of fundus diseases, and its targeted intervention may also become a potential treatment for fundus diseases.
