ABSTRACT

Aim To explore its potential biological basis and the endogenous metabolic characteristics of urine during the formation of primary dysmenorrhea via untargeted urine metabolomics. Methods Twenty SD rats were randomly divided into control group and model group. The primary dysmenorrhea model was reproduced by estradiol benzoate combined with oxytocin, and the contrrol group took food and water freely. The differential metabolites and core metabolic pathways were found by multivariable pattern recognition method combined with ultra-high performance liquid chromatography quadrupole time-of-flight mass spectrometry. The receiver operating characteristic ( ROC ) curve was drawn by metaboanalyst 5.0 platform to evaluate the clinical diagnostic efficacy of core metabolites. Results A total of 46 metabolites with significant differences, such as hippuric acid, phenylacetaldehyde, prostaglandin G2, 6-hydroxy-5-methoxyindole glucuronide, were screened, mainly involving phenylalanine metabolism, pentose and glucuronate interconversions, and arachidonic acid metabolism. ROC curve showed that the area under the curve of four core biomarkers was greater than 0.7. Conclusions Different metabolic maps are presented in different progressive stages of primary dysmenorrhea, mainly involving the disorders of fatty acid metabolism, carbohydrate metabolism and amino acid metabolism. Meanwhile, the extracted characteristic bi¬omarkers have high diagnostic value for the evaluation of primary dysmenorrhea.

ABSTRACT

A 10-day-old male infant presented with skin erythema and blisters for 6 days. Skin examination showed scattered or confluent erythema all over the body, tense blisters of varying sizes on the normal skin or an erythematous base, and some blisters were ulcerated and erosive; bloody bullae and erythematous erosive patches could be seen on the oral mucosa. Histopathological examination revealed subepidermal blisters, and there were some neutrophils and a few eosinophils in the blisters. Direct immunofluorescence assay showed homogeneous linear IgA and granular C3 deposits along the basement membrane zone, without IgG deposits. The diagnosis of neonatal linear IgA bullous dermatosis was confirmed. After comprehensive treatments including nutritional support and anti-infection treatment, skin erythema and blisters subsided, and the mucosal damage was attenuated. The telephone follow-up 16 months after discharge showed that the infant was in good general condition with normal growth and development, and the oral mucosal lesions had subsided and healed, without new skin lesions.

ABSTRACT

BACKGROUND@#Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations.@*METHODS@#In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively.@*RESULTS@#81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count.@*CONCLUSIONS@#In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

ABSTRACT

Antiphospholipid syndrome (APS) is characterized by arterial and venous thrombosis and(or) morbid pregnancy, accompanied by persistent antiphospholipid antibody (aPL) positivity. However, due to the complex pathogenesis of APS and the large individual differences in the expression of aPL profiles of patients, the problem of APS diagnosis, prognosis judgment and risk assessment may not be solved only from antibody level. It is necessary to use new technologies and multiple dimensions to explore novel APS biomarkers. The application of next generation sequencing (NGS) technology in diseases with high incidence of somatic mutations, such as genetic diseases and tumors, has been very mature. Thus, gradually understanding the research and application progress of APS by NGS technology from genome, transcriptome, epigenome and other aspects is meaningful. This article reviews the related research of NGS technology in APS, and provide more reference for the deep understanding of the APS-related screening markers and disease pathogenesis.

ABSTRACT

Microphthalmos-anophthalmos-coloboma(MAC)is structurally and clinically correlated congenital ocular malformation. Although MAC is relatively rare, they still become an important cause of blindness in children. At present, the etiology of MAC is not clear; a variety of genetic or environmental factors may cause MAC. Because of its special anatomical structure, MAC has complex clinical manifestations and multiple complications. The complications including cataract, angle-closure glaucoma, uveal effusion, retinal detachment, orbital cyst, which are often accompanied with increased risks for surgery and poor prognosis. By summarizing the clinical features, the common types of ocular complications, and the progress of the treatment, this article will enhance clinicians' cognition of MAC and guide clinicians to formulate personalized and safe treatment plans for patients.

ABSTRACT

ObjectiveTo study the clinical efficacy of the Qingre Lishi Huazhuo method on patients with chronic gouty arthritis of dampness-heat obstruction syndrome and the effect on nucleotide-binding oligomerization domain-like receptor 3(NLRP3)/interleukin-1β (IL-1β) signaling pathway to preliminarily explore its mechanism. MethodSixty patients with chronic gouty arthritis of dampness-heat obstruction syndrome were enrolled and divided into a treatment group (30 cases) and a control group (30 cases) according to the random number table method. Thirty people were assigned to the healthy group. Patients in the control group were treated with oral Febuxostat, while those in the treatment group were treated with modified Simiaosan combined with Febuxostat. Treatment lasted four weeks. The general clinical data, traditional Chinese medicine (TCM) syndrome scores, serum uric acid (UA), serum creatinine (SCr), blood urea nitrogen (BUN), fasting blood glucose (FPG), low-density lipoprotein (LDL), triglyceride (TG), total cholesterol (TC), erythrocyte sedimentation rate (ESR), and C-reactive protein (CRP) of patients were recorded. Enzyme-linked immunosorbent assay (ELISA) was employed to measure the levels of IL-1β,TNF-α, and IL-6,and the levels of NLRP3,cysteinyl aspartate-specific protease-1 (Caspase-1), and apoptosis-associated speck-like protein containing a CARD (ASC) were detected by Western blot. ResultBefore treatment, the levels of body mass index (BMI), systolic blood pressure (SBP),diastolic blood pressure (DBP),UA,SCr,BUN,FPG,LDL,TG,and TC in both groups significantly increased (P<0.05,P<0.01),and the levels of HDL significantly decreased as compared with those in the healthy group(P<0.05). Additionally, the levels of IL-1β, TNF-α, and IL-6 in both groups significantly increased before treatment (P<0.01). Compared with the results before treatment, patients in the two groups had significant reductions in tube pain, joint tenderness, joint swelling,joint fever, activity disorders, body fatigue, sliminess, bitter mouth, yellow and red urine, and tongue manifestation scores (P<0.05,P<0.01). Compared with patients in the control group after treatment, those in the treatment group had a significant decrease in joint fever, body fatigue, sliminess, bitter mouth,sticky stool,yellow and red urine, tongue manifestation score, and pulse score (P<0.05). The total effective rate in the treatment group was 80.0% (24/30), higher than 56.7% (17/30)in the control group(χ2=11.916,P<0.05). Compared with the results before treatment, BMI, SBP, DBP, UA, SCr, BUN, FPG, LDL, TG, TC, ESR,CRP, IL-1β, TNF-α, IL-6 levels, and VAS score in both groups significantly decreased (P<0.05,P<0.01). Compared with patients in the control group after treatment, those in the treatment group had decreased DBP,ESR, IL-1β levels, and VAS score (P<0.05). Western blot results showed that before treatment, the protein expression of NLRP3, Caspase-1, and ASC in peripheral blood mononuclear cells (PBMCs) of patients in both groups were higher than those in the healthy group (P<0.01). Compared with the results before treatment, the protein expression of NLRP3, Caspase-1, and ASC in PBMCs in patients of both groups after treatment decreased (P<0.05,P<0.01). Compared with the control group after treatment, the treatment group showed decreased expression levels of NLRP3 and Caspase-1(P<0.05). ConclusionThe Qingre Lishi Huazhuo method can effectively improve the clinical symptoms and reduce inflammation of chronic gouty arthritis of dampness-heat obstruction syndrome with good safety. The mechanism may be related to the inhibition of the NLRP3/IL-1β signaling pathway.

ABSTRACT

Soybean mosaic virus (SMV) is a critical pathogen that reduces the soybean yield and seed quality worldwide, and SMV has a restricted natural host range. In this study, we used sequence-independent amplification (SIA) methods to identify the viruses that may cause the Atractylodes macrocephala Koidz disease. Results revealed that there is SMV in diseased Atractylodes macrocephala leaves, and we named this isolate as SMV-Am. To further characterize the genomic structural and phylogenetic relationships of SMV-Am, genomic dsRNA was extracted, and the genomic sequence was amplified by RT-PCR and RACE. The results of bioinformatics analysis showed that the genomic RNA of SMV-Am is 9587 nucleotides in length, which conforms to the typical characteristics of Potyvirus. According to the sequence alignment of complete nucleotide sequences, SMV-Am showed the highest level of nucleotide homology and amino acid sequences to SMV-Liaoning, 96. 57% and 98. 86%, respectively. In addition, phylogenetic analysis based on the nucleotide sequences of other SMV isolates of SMV-Am revealed that SMV-Am was most closely related to SMV-Liaoning. Then, the SMV-Am protein was further analyzed by I-TASSER and PyMOL software, revealing that the key amino acid mutations led to the structural changes of P1, HC-Pro, P3, 6K2, NIa-pro and NIb proteins, with P1 the most obvious. Finally, recombination has been detected at the position of 6560-8950 nucleotides, the main parent is the isolate SMV-XFQ012 (accession number KP710875. 1), and the secondary parent is isolate SMV-pCB301-SC15 (accession number MH919386. 1). This study is the first report of SMV in Atractylodes macrocephala Koidz, and these results are expected to provide a scientific basis for the prevention and control of SMV infection on Atractylodes macrocephala Koidz.

ABSTRACT

Human genetic resources are an important strategic resource for the development of science and technology in China. In order to fully utilize and effectively protect human genetic resources in real-world studies, through analyzing the status and characteristics of real-world studies, this study found that the number of real-world studies was increasing year by year, and with some characteristics, such as many uncontrollable factors, strict requirements for evidence formation, and easy information acquisition and disclosure. Combined with the characteristics of real-world studies, the ethical issues of human genetic resource management in real-world studies were summarized into three aspects, including scientific and value of research development, informed consent and privacy protection of subjects, and fairness and justice in benefit sharing. Accordingly, the key points of ethical review were proposed as scientific rationality, fully informed consent and privacy, as well as data security and stakeholders. In addition, it is necessary to give full play to the role of ethical review in research access and process supervision responsibilities, guide researchers to make full use of human genetic resources by strengthening training and process management, and further promote the standardization of real-world studies.

ABSTRACT

Objective:To explore the effect of different glucose concentrations on the uptake of 18F-FDG and the expression of glucose transport protein(Glut)-1 and Glut-3 in non-small cell lung cancer (NSCLC). Methods:NSCLC cell line A549 cells were cultured in DMEM medium with glucose concentrations of 3.9, 5.0, 6.1, 8.3 and 11.1 mmol/L respectively for 24 h. Then 3.7×10 4 Bq 18F-FDG was added into each group and γ counter was used to measure the radioactivity count 1 h later. Western blot was used to examine the expression of Glut-1 and Glut-3. One-way analysis of variance and Bonferroni test were used for data analysis. The correlation was analyzed by Pearson correlation analysis. Results:The 18F-FDG uptake rates in 3.9, 5.0, 6.1, 8.3 and 11.1 mmol/L groups were (4.89±0.83)%, (4.07±0.23)%, (3.66±0.29)%, (3.34±0.16)% and (3.29±0.24)%, respectively ( F=7.05, P=0.006). Compared with 3.9 mmol/L group, the 18F-FDG uptake rates in 8.3 and 11.1 mmol/L groups were reduced and differences were statistically significant ( P values: 0.013, 0.010), while there were no statistical differences between the other groups ( P values: 0.057-0.999). The relative expressions of Glut-1 and Glut-3 in each group were 1.17±0.10, 1.00±0.00, 0.84±0.07, 0.70±0.18, 0.61±0.16, and 1.14±0.05, 1.00±0.00, 0.86±0.12, 0.71±0.05, 0.40±0.06, respectively ( F values: 10.26 and 51.94, P values: 0.001, <0.001). Moreover, the 18F-FDG uptake rates were positively correlated with the expression of Glut-1 and Glut-3 ( r values: 0.775 and 0.744, both P=0.001). Conclusions:When the glucose concentration fluctuates within 3.9-11.1 mmol/L, the change of glucose will affect the 18F-FDG uptake rate and the expression of Glut-1 and Glut-3 in A549 cells. Moreover, the 18F-FDG uptake rate is related to the expressions of Glut-1 and Glut-3.

ABSTRACT

Rich experience of clinical diagnosis and treatment has been accumulated in the developmental history of Chinese medicine, and the efficacy has been increasingly accepted by the public. However, the evaluation of clinical efficacy is currently based more on scientific evidence instead of merely the changes of patient symptoms. In Chinese medicine, the changes of major disease indicators, patient symptoms, and pathogenesis are the major criteria for the evaluation of clinical efficacy. The lack of well-accepted and uniform criteria and the uncertainty of subjective evaluation limit the development of clinical Chinese medicine. Evidence-based medicine combines clinical skills with the current best evidence. Narrative medicine, utilizing people's narratives in clinical practice, emphasizes patient feelings, willingness, and value orientation. The introduction of both evidence-based medicine and narrative medicine into the evaluation of clinical efficacy refers to the construction of the clinical efficacy evaluation system in a paradigm of participatory diagnosis and treatment. It can fully reflect the characteristics of Chinese medicine, respect the values of patients, and achieve universal clinical evidence. Therefore, it helps to improve the diagnosis and treatment, the relationship between doctors and patients, patients' life quality and decision-making awareness, and finally the new evaluation model of clinical efficacy of Chinese medicine.
