ABSTRACT

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.

ABSTRACT

Due to the successful application of all-trans retinoic acid (ATRA) and arsenic, the treatment of acute promyelocytic leukemia (APL) with PML::RARA fusion gene has achieved great success. However, some patients are presented with APL phenotype in cellular morphology, immunophenotype, and gene expression profile, while PML::RARA is negative, which is known as atypical APL (aAPL). In aAPL patients, more than 20 fusion genes related to retinoic acid receptors have been reported. It has been discovered that all evaluable patients with RARG fusion genes and approximately half of those with rare RARA fusion genes are resistant to ATRA, however, the molecular mechanisms of this resistance remain poorly studied. Combining with the reports in the 65th American Society of Hematology Annual Meeting, this paper reports great progresses of the key pathogenesis of aAPL and ATRA resistance mechanisms.

ABSTRACT

Lysophosphatidylcholine acyltransferase 1(LPCAT1),a key metabolic enzyme in the phosphatidyl-cho-line metabolism pathway,mediates phosphatidylcholine synthesis through deacylation-reacylation,which leads to alterations in the phospholipids composition of cell membranes and the remodelling of the cellular cytoskeleton.Ly-sophosphatidylcholine acyltransferase 1 has been shown to be highly expressed in gastric,breast and colorectal cancer,and can accelerate the alteration of the phospholipids composition of tumor cell membranes or interact with tumor driver genes,such as epidermal growth factor receptor and cell cycle-related genes.It might promote tumor development by affecting tumor cell proliferation,migration,invasion and resistance to chemotherapy.

ABSTRACT

Based on the method of regulating qi and resolving toxins, this paper discussed the core pathogenesis of “inflammation-cancer” transformation of ulcerative colitis. It is believed that the disorder of qi movement, endogenous pathogenic factors of “heat, stasis and dampness” are cemented in the large intestine, and the pathogenic factors are too excessive to be solved, which will become toxic after a long time and lead to cancerous changes. Clinical prevention and treatment applies the method of regulating qi and resolving toxins, and the method of regulating qi was proposed as clearing internal qi, regulating blood qi and strengthening spleen qi, so as to clear heat, dissipate blood stasis and dissolve dampness; different methods of regulating qi and resolving toxins were flexibly combined according to the pathogenic characteristics of different stages of toxicity, in order to interrupt the process of “inflammation-cancer” transformation of ulcerative colitis.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

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.

ABSTRACT

OBJECTIVE@#To analyze the clinical data and genetic characteristics of a child with fibrocartilage hyperplasia type 1 (FBCG1).@*METHODS@#A child who was admitted to Gansu Provincial Maternity and Child Health Care Hospital on January 21, 2021 due to severe pneumonia and suspected congenital genetic metabolic disorder was selected as the study subject. Clinical data of the child was collected, and genomic DNA was extracted from peripheral blood samples from the child and her parents. Whole exome sequencing (WES) was carried out, and candidate variants were verified by Sanger sequencing.@*RESULTS@#The patient, a 1-month-old girl, had presented with facial dysmorphism, abnormal skeletal development, and clubbing of upper and lower limbs. WES revealed that she has harbored compound heterozygous variants c.3358G>A/c.2295+1G>A of the COL11A1 gene, which has been associated with fibrochondrogenesis. Sanger sequencing has verified that the variants have been respectively inherited from her father and mother, both of whom were phenotypically normal. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the c.3358G>A variant was graded as likely pathogenic (PM1+PM2_Supporting+PM3+PP3), and so was the c.2295+1G>A variant (PVS1+PM2_Supporting).@*CONCLUSION@#The compound heterozygous variants c.3358G>A/c.2295+1G>A probably underlay the disease in this child. Above finding has facilitated definite diagnosis, genetic counseling for her family.

ABSTRACT

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.

ABSTRACT

To explore the allergen sensitization status of patients with respiratory allergic diseases in Shanxi Province, and to provide a basis for the diagnosis, treatment and prevention of allergic diseases. It is a cross-sectional study, a total of 1 680 patients with allergic rhinitis and/or asthma diagnosed at the Department of Allergic Reaction of Shanxi Bethune Hospital from July 2021 to June 2023 who underwent allergen sIgE testing and/or skin prick test were retrospectively enrolled.There were 772 males and 908 females.The age range was 3 to 88 years. The median age was 35 years.There were 108 cases in the child group (≤12 years old), 102 cases in the adolescent group (13-17 years old), 819 cases in the youth group (18-40 years old), 498 cases in the middle-aged group (41-65 years old), and 153 cases in the elderly group (>65 years old). There were 333 cases in the allergic rhinitis group, 827 cases in the allergic asthma group, and 520 cases in the allergic rhinitis with asthma group. There were 1 254 urban patients and 426 rural patients.There were 253 cases in the northern Shanxi region, 1 195 cases in the central Shanxi region, and 232 cases in the southern Shanxi region. Statistical analyses were performed using the χ 2 test or Fisher's exact probability method to compare the differences in allergen sIgE positivity rates by sex, age, disease, living environment, and geography. The results showed that 1 027 patients (61.1%) were positive for at least one allergen sIgE, with Artemisia having the highest rate of positivity (603/1 680, 35.9%), followed by ragweed (302/1 680, 18.0%) and dust mite combinations (245/1 680, 14.6%). The number of individuals with single-allergen sIgE positivity was 357 (357/1 027, 34.8%), with the highest number of single-allergen sIgE positive results associated with Artemisia (114/357, 31.9%). The number of multiple-allergen sIgE positive results was 670 cases (670/1 027, 65.2%), with the highest number of patients having 2 allergen sIgE positive results (243/670, 36.3%). The overall positivity rate for allergen sIgE was significantly higher among males than among females (65.7% vs. 57.3%, χ2=12.405, P<0.001). Overall positivity for inhalant allergen sIgE was higher in the child and adolescent groups (88.0% vs. 88.2% vs. 59.8% vs. 40.2% vs. 19.0%, χ2=223.372, P<0.001), and food allergen sIgE positivity was highest in the child group (54.6% vs. 36.3% vs. 26.0% vs. 18.9% vs. 21.6%,χ2=66.383,P<0.001). The sIgE positivity rate of inhalant allergens was significantly higher in the allergic rhinitis group and the allergic rhinitis with asthma group than in the allergic asthma group, except for cockroaches and molds (P<0.05). The overall positive rate of allergen sIgE was significantly higher among urban patients than among rural patients (66.2% vs. 46.2%, χ2=53.230, P<0.001). The difference in the overall positive rate of allergen sIgE among patients from different regions was not statistically significant (56.1% vs. 62.0% vs. 62.1%, χ2=3.140, P=0.208). The sIgE positivity of dust mite combinations was significantly higher in the central Shanxi region and the southern Shanxi region than in the northern Shanxi region (15.5% vs. 18.1% vs. 7.1%,χ2=14.411, P=0.001). In conclusion, artemisia was the most important sensitizer for respiratory allergic diseases in Shanxi Province. The types of allergens and positivity rates were different for different sexes, ages, diseases, living environments, and regions. Therefore, patients with allergic diseases should be tested for allergens to help with the diagnosis, treatment and prevention of allergic diseases.

ABSTRACT

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.

ABSTRACT

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.
