RESUMO
ObjectiveTo establish a dose-effect curve for semi-automatic analysis of dicentric chromosomes(DC) based on an automatic chromosome analysis system. Methods A total of three healthy volunteers were recruited as the study subjects, and their peripheral blood was collected and stimulated by X-ray at doses of 0.00, 0.10, 0.25, 0.50, 0.75, 1.00, 2.00, 3.00, 4.00, and 5.00 Gy, with the absorbed dose rate of 1.0 Gy/min. Images of DC in the mid-stage of cell division were collected using a high-throughput automatic chromosome analysis system. The DCScore software was used to automatically analyze DC aberrations, and a dose-effect curve for semi-automatic analysis of DC was fitted after manual confirmation. The fitted dose-effect curve for semi-automatic analysis of DC was validated for accuracy using three proficiency test samples from the national quality assessment of biological dose. Results The incidence of DC increased with increasing irradiation doses in the range of 0.00-5.00 Gy (P<0.01). The dose-effect curve for the fitted semi-automatic analysis of DC was ŷ =0.000 8 (±0.000 2) +0.009 2(±0.000 9) D+0.014 2(±0.000 4) D2 (R2= 0.999 8). The relative deviation between the estimated dose and the actual dose of the three test samples was about 20.00%, indicating curve applicability for biological dose estimation. Moreover, excluding the time spent on manual analysis, the semi-automatic analysis method increased the analysis efficiency by 26.0 times. Conclusion The semi-automatic analysis dose-effect curve for DC stimulated by X-ray is constructed for biological dose estimation, which can reduce the manual analysis time, and holds great potential for application in nuclear emergency response to large-scale radiation accidents.
RESUMO
OBJECTIVE To study the improvement effect and mechanism of sanguinarine (SG) on inflammatory pain in rats with lumbar disc herniation (LDH) and its mechanism. METHODS LDH model rats were established and divided into model group, SG low-dose, medium-dose and high-dose groups (1.00, 2.50, 6.25 mg/kg), high-dose of SG+Anisomycin [mitogen-activated protein kinase (MAPK) activator] group (6.25 mg/kg SG+5 mg/kg Anisomycin), with 10 rats in each group. Another 10 rats were included as the control group. Each group was given corresponding drugs intraperitoneally, while the control group and model group were given an equal volume of normal saline intraperitoneally, once a day, for 7 consecutive days. The general situation and neurological changes of rats in each group were observed, and the pain threshold [including paw withdrawal mechanical threshold (PWMT) and paw withdrawal thermal latency (PWTL)] of rats was determined; the histopathological changes of dorsal root ganglion (DRG) were observed in rats. The serum levels of inflammatory factors [tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β)] and pain factors [neuropeptide Y (NPY), 5-hydroxytryptamine (5-HT)] in rats were detected.The positive expressions of ionized-calcium binding adaptor molecule-1 (Iba-1) in spinal cord microglia and glial fibrillary acidic protein (GFAP) in astrocytes were observed. The expressions of proteins related to MAPK/extracellular signal-regulated kinase (ERK)/nuclear factor κB (NF-κB) signaling pathway, TNF-α and IL-1β proteins were detected in DRG tissue of rats. RESULTS Compared with the control group, the rats in the model group showed decreased appetite, hindlimb movement disorders, and disordered neuronal cell arrangement, the neurological score, the levels of TNF-α, IL-1β, NPY, the positive expressions of Iba-1 and GFAP, the phosphorylations of p38 MAPK, ERK1/2 and NF-κB p65, the protein expressions of TNF-α and IL-1β were significantly increased (P<0.05); PWMT, PWTL and the levels of 5-HT were significantly reduced (P<0.05). Compared with the model group, the rats of SG groups showed some relief in their mental appetite and hindlimb motor disorders, the intervertebral disc structure of DRG was restored, and the levels of the above quantitative indicators had significantly reversed (P<0.05). Anisomycin reversed the improvement effect of SG on inflammatory pain in LDH rats. CONCLUSIONS SG can improve inflammatory pain by inhibiting the activation of microglia in DRG tissue of LDH rats, reducing the release of inflammatory factors, and increasing pain threshold, and its mechanism of action may be related to the inhibition of MAPK/ERK/NF- κB signaling pathway.

Conclusion:The combined score of leading STM, NLR and PLR is an independent factor influencing OS in patients receiving immunotherapy for gastric cancer, and can predict the efficacy of immunotherapy for gastric cancer.
RESUMO
The "four-in-one" approach is based on the four-dimensional perspective of "property, position, tendency and syndrome", which helps to identify and analyze classical prescriptions in a multi-dimensional and three-dimensional way. The early pathogenesis of chronic heart failure (CHF) is deficiency of heart Qi and heart Yang and disorder in Qi transformation in triple energizer, while in the later stage of the disease, it progresses from deficiency to excess, with simultaneous occurrence of deficiency and excess syndromes. Fuling Guizhi Baizhu Gancao Decoction (Linggui Zhugan Decoction) plays its role in treating chronic heart failure by the four elements of "property, position, tendency and syndrome". Property—Linggui Zhugan Decoction is pungent, sweet, slight sweet and bitter in flavor, but warm in property. The sweet is able to tonify deficiency; the pungent is responsible for dispersing Yang, promoting Qi and draining water retention; the warm nourishes the spleen, raises Yang Qi and resolves phlegm; the bitter could excrete diuresis and dry dampness to guarantee the smooth operation of three energizer. Position-Linggui Zhugan Decoction acts on the heart, spleen and triple energizer. It can stimulate heart Yang, strengthen the spleen, resolve phlegm, and regulate the waterways to promote the Qi transformation in triple energizer. Tendency-The tendency of Linggui Zhugan Decoction is upward and downward in parallel, both internal and external. Warming up and promoting diuresis, raising Yang up and tonifying deficiency, it is conducive to the Yang Qi transformation in triple energizer. Syndrome-Linggui Zhugan Decoction is indicated for the syndrome of heart Yang deficiency and water-fluid retention, which begins with the upper abdomen swelling, Qi rushes against the chest. It is widely used in the treatment of water-vapor impulse heart disease. The disorder of Qi transformation in triple energizer is the main mechanism of recurrent CHF. Linggui Zhugan Decoction can not only warm the fire of Qi transformation in triple energizer, but also smooth the pathway of Qi transformation in triple energizer, which is compatible with the treatment of systemic fluid retention in chronic heart failure. Its pharmacological mechanisms include anti-inflammation, anti-platelet aggregation, regulation of cardiomyocyte cell membrane ion channels, protection against ischemia-reperfusion injury and modulation of vasodilation, etc. Deconstructing Linggui Zhugan Decoction with "four-in-one" approach and discussing its mechanism for treating CHF in combination with the theory of "Qi transformation in triple energizer", have great significance to rejuvenate the vitality of classical prescriptions and to apply them accurately and effectively.

RESUMO
Pulmonary fibrosis, chronic obstructive pulmonary disease, acute lung injury, asthma, and infectious pneumonia are common pulmonary inflammatory diseases worldwide. There is evidence that mitochondria produce a large amount of reactive oxygen species (ROS) when stimulated by inflammation, leading to oxidative stress that affects the onset and progression of pulmonary inflammatory diseases. With in-depth research, traditional Chinese medicine (TCM) has made significant progress in the treatment of pulmonary inflammatory diseases. An increasing amount of evidence indicates that single TCM and their active components, as well as TCM compound formulas, can improve mitochondrial oxidative stress status through multi-target and multi-pathway mechanisms, thereby effectively treating pulmonary inflammatory diseases. Currently, there is a lack of systematic review and summary of TCM research in this field both domestically and internationally. Therefore, this article aims to summarize and conclude the mechanisms by which TCM regulates mitochondrial oxidative stress to intervene in pulmonary inflammatory diseases, providing a scientific basis for its clinical application and offering new ideas and references for in-depth research on the prevention and treatment of pulmonary inflammatory diseases with TCM.

RESUMO
Exosomes are nanoscale extracellular vesicle structures that communicate and exchange information between cells. They carry a variety of biologically active molecules whose compositions and contents vary according to the origin and recipient cells. Therefore, exosomes can be used as biomarkers. Neurodegenerative diseases are diseases with hidden onset, so early screening and accurate diagnosis is undoubtedly a reliable guarantee to reduce their mortality and increase the cure rate. Exosomes, as a research hotspot in recent years, have great potential for the diagnosis and treatment of diseases given their transport capacity and contents, and have significant advantages in abundance, stability, diversity and accessibility. The purpose of this paper is to discuss exosomes as potential candidates for early diagnosis of neurodegenerative diseases, and thus to elaborate new fields of their application, with a view to providing a richer perspective for clinical prediction and treatment.

In recent years, with the development of neurointerventional techniques, transradial approach (TRA) has been able to meet most needs of neurointerventional procedures. Compared with tranfemoral approach (TFA), TRA can obviously reduce access-site complications, shorten hospital stays and improve patient satisfaction. However, due to the long learning curve, lack of radial-specific catheters, small artery diameter and specific vascular access-site complications, TRA development is relatively slow, and relevant domestic and foreign studies are still at initial stage. Therefore, this article mainly focuses on the anatomy, advantages and limitations, approaches of radial artery, and discuss the safety and feasibility of TRA in neurointerventional diagnosis and treatment, in order to provide more references for neurointerventionalists.
RESUMO
Objective@#This study aimed to investigate the impact of molecular classification and PTEN, KRAS and PIK3CA gene mutation on the outcome of fertility-preserving treatment in the patients with endometrioid endometrial cancer (EEC) and endometrial atypical hyperplasia (EAH). @*Methods@#This is a single-center retrospective study. A total of 135 patients with EEC and EAH receiving fertility-preserving treatment and molecular classification were reviewed. The distribution of the four types of molecular classification was described. The impact of non-specific molecular profile (NSMP), mismatch repair-deficiency (MMRd), and PTEN, KRAS and PIK3CA gene mutation on the outcome of fertility-preserving treatment was analyzed. @*Results@#Of the patients analyzed, 86.7% (117/136) were classified as having NSMP; 14 (10.4%), MMRd; 1 (0.7%), POLEmut EAH; and 3 (2.2%), p53abn EEC. The patients having NSMP and MMRd achieved similar 16-, 32-, and 48-week complete response rates. The patients harboring tier I and tier II PTEN mutations (PTENmut-Clin) achieved lower cumulative 32-week CR rates than those with PTEN-others (without PTENmut-Clin) (22/47, 46.8% vs. 50/74, 67.6%; p=0.023; odds ratio=0.422; 95% confidence interval [CI]=0.199–0.896). Insulin-resistance (hazard ratio [HR]=0.435; 95% CI=0.269–0.702; p=0.001) and PTENmut-Clin (HR=0.535; 95% CI=0.324–0.885; p=0.015) were independent negative predictors for lower 32-week CR rates. @*Conclusion@#PTENmut-Clin is an independent risk factor for unfavorable fertility-preserving treatment outcomes in the patients with EEC and EAH. The patients with MMRd receiving fertility-preserving treatment achieved outcomes similar to those of the patients with NSMP. The molecular profiles might guide fertility-preserving treatment in the prognosis and clinical decisions.
