RESUMO

Aim: A rapid and precise diagnostic method is crucial for timely intervention and management of tuberculosis. The present study compared the diagnostic accuracy of a novel lipoarabinomannan (LAM) antigen test, AIMLAM, for tuberculosis in urine samples. Methodology: The study subjected 106 TB suspects to smear microscopy, MGIT, GeneXpert and AIMLAM. Results: Among 106, smear microscopy identified 36 as positive (33%) (sensitivity; 70.93%, 95% CI (60.14-80.22%), while MGIT showed 38 positive (36.8%). GeneXpert detected 59 positives (sensitivity; 96.83, 95% CI (89.00-99.61%)). AIMLAM declared 61 as positive (57.5%) (sensitivity; 100.00, 95% CI (94.13-100.00%) and 45 as negative (42.5%). Conclusion: Overall, AIMLAM demonstrated better diagnostic accuracy than GeneXpert Assay, smear microscopy and MGIT liquid culture in urine samples.


This study describes a new way to detect tuberculosis, called AIMLAM. Unlike traditional methods that use sputum or blood, AIMLAM tests urine samples and bodily fluids. It is automated and uses easily accessible samples to identify a tuberculosis infection, so may be a convenient and noninvasive option for healthcare providers. The test shows promising results in terms of accuracy and sensitivity.

RESUMO

How are Asian and Black men and women stereotyped? Research from the gendered race and stereotype content perspectives has produced mixed empirical findings. Using BERT models pre-trained on English language books, news articles, Wikipedia, Reddit and Twitter, with a new method for measuring propositions in natural language (the Fill-Mask Association Test, FMAT), we explored the gender (masculinity-femininity), physical strength, warmth and competence contents of stereotypes about Asian and Black men and women. We find that Asian men (but not women) are stereotyped as less masculine and less moral/trustworthy than Black men. Compared to Black men and Black women, respectively, both Asian men and Asian women are stereotyped as less muscular/athletic and less assertive/dominant, but more sociable/friendly and more capable/intelligent. These findings suggest that Asian and Black stereotypes in natural language have multifaceted contents and gender nuances, requiring a balanced view integrating the gender schema theory and the stereotype content model. Exploring their semantic representations as propositions in large language models, this research reveals how intersectional race-gender stereotypes are naturally expressed in real life.

RESUMO

OBJECTIVE To evaluate the cost-effectiveness of ivabradine in the treatment of chronic heart failure (CHF) in the context of “Quadruple Therapy” from the perspective of the health system. METHODS Based on real-world cohort data, the Markov model was constructed according to the natural progression of CHF, with a cycle time of 3 months, a study timeframe of 20 years, and a discount rate of 5%. Using quality-adjusted life year (QALY) and incremental cost-effectiveness ratios (ICER) as the output indexes, the cost-utility analysis was used to evaluate the cost-effectiveness of ivabradine in combination with the “Quadruple Therapy” regimen, compared with the “Quadruple Therapy” regimen for the treatment of CHF, and the robustness of the results of the base analysis was verified by univariate sensitivity analysis and probabilistic sensitivity analysis. RESULTS The results of the base analysis showed that the ICER of ivabradine combined with the “Quadruple Therapy” regimen was 165 065.54 yuan/QALY, compared with the “Quadruple Therapy” regimen, which was lower than the willingness-to-pay (WTP) threshold (257 094 yuan/QALY) based on 3 times of China’s gross domestic product (GDP) per capita in 2022. The results of the univariate sensitivity analysis showed that the discount rate had the greatest impact on the robustness of the model. The probabilistic sensitivity analysis showed that the probability that the ivabradine combined with the “Quadruple Therapy” regimen was cost-effective under the WTP threshold in this study was 59.50%. CONCLUSIONS When using 3 times China’s 2022 GDP per capita (257 094 yuan/ QALY) as the WTP threshold, the combination of ivabradine and the “Quadruple Therapy” regimen for treating CHF is cost- effective.

RESUMO

In recent years, transcatheter arterial chemoembolization (TACE) has emerged as a common treatment modality for the treatment of hepatocellular carcinoma (HCC). However, with the ongoing development of embolic agent techniques, the new advances in microspheres and nanoparticles have brought new hope for improving the efficacy and safety of TACE. This article reviews the latest advances and applications of microspheres and nanoparticles in TACE for HCC. First, this article introduces the background of TACE as a therapeutic approach and the emergence of microsphere and nanoparticle techniques, and then it describes the application of various types of microspheres and nanoparticles in TACE and discusses the requisite attributes of an ideal embolic agents. The article focuses on the advances in material science and engineering, as well as the clinical efficacy of drug-eluting microspheres and nanoparticles versus conventional TACE. Furthermore, it discusses the importance of radiological examination in TACE and summarizes the research advances in the radiopaque and magnetic resonance-visible embolic agents. This article also explores the future development directions and challenges of TACE. It also points out the combination of microspheres and nanoparticles with other treatment modalities, the application of personalized and precision medicine in TACE, and the potential regimen of TACE in clinical translation, and meanwhile, it raises the issues of ethics and regulation that need to be further discussed. It is believed that microspheres and nanoparticles have a potential effect in TACE, which provides a theoretical basis and technical support for innovating HCC treatment regimens and improving the prognosis of patients through TACE interventions.

RESUMO

OBJECTIVE To evaluate the effects of ivabradine on vascular endothelial function in patients with coronary artery disease. METHODS PubMed, Embase, the Cochrane Library, Web of Science, CNKI, Wanfang Data, VIP and CBM databases were retrieved to collect randomized controlled trials (RCTs) about ivabradine (intervention group) versus placebo or β-blocker (control group) from the inception to Mar. 20th 2023. The meta-analysis was performed by using RevMan 5.4 software after literature screening, data extraction and quality evaluation. RESULTS A total of 12 RCTs were included, involving 1 206 patients. The results of meta-analysis showed that the levels of flow-mediated dilation (FMD) [MD=1.71, 95%CI (0.96, 2.46), P<0.000 01] and nitric oxide (NO) [MD=5.80, 95%CI (5.02, 6.59), P<0.000 01] in the intervention group were significantly higher than control group, while endothelin-1(ET-1) level was significantly lower than control group [MD=-7.45, 95%CI (-8.42, -6.47), P<0.000 01]. There was no statistical significance in nitroglycerin-mediated dilation (NMD) level between 2 groups [MD=0.13, 95%CI(-0.74, 1.00), P=0.77]. Subgroup analyses based on the different medications and intervention time in the control group showed better improvement in FMD level of patients receiving ivabradine, compared with placebo (P<0.05); compared with placebo and β-blocker, the level of NO in patients receiving ivabradine was improved significantly (P<0.05), while ET-1 level was decreased significantly (P<0.05). Regardless of the duration of the intervention, the levels of FMD, NO, and ET-1 in the intervention group were significantly improved compared to the control group (P<0.01), while the difference in NMD was not statistically significant (P>0.05). CONCLUSIONS Ivabradine can improve vascular endothelial function in patients with coronary artery disease.

RESUMO

Lakes on the Qinghai-Tibet Plateau (QTP) have been subject to multiple environmental pressures from rapid climate change and intensified human activity in recent decades. However, their ecological effects on the lake ecosystem remain largely unclear due to the lack of long-term monitoring data. This study presented the environmental and ecological changes of the lake Yamzhog Yumco (Southern QTP) over the past three decades based on multi-proxy analysis (geochemistry and sedaDNA) on a high-time resolution sediment core. The result showed that the lake exhibited a continuous eutrophication process from 2004 CE, which has accelerated since 2014 CE. The nutrient enrichment was mainly attributed to anthropogenic emissions from the catchment. The sedimentary ancient DNA (sedaDNA) metabarcoding data registered a sensitive response of aquatic communities to the additional nutrient supply. Eukaryotic algae and aquatic invertebrate communities exhibited similar temporal dynamics, characterized by the increase in eutrophic taxa and the decrease in oligotrophic taxa. Change points analysis suggested that lake ecosystems underwent a slight ecological shift in 2003 CE and an abrupt shift in 2012 CE driven by nutrient enrichment. Quantitative analysis revealed that nutrients and human activity accounted for 27.9 % and 21.7 % of the temporal variation in aquatic communities, whereas climate change only explained 6.9 % of the total variation. From a paleolimnological view, our study supported that regional human activity could distinctly alter the nutrient level and aquatic community structure of lake ecosystems in the QTP. Considering that anthropogenic disturbance will continuously increase, it is crucial to strengthen the field monitoring of the lakes on the plateau and make effective management measures to avoid irreversible ecological consequences.

RESUMO

Four new δ- and γ-lactone derivatives, hyperelatolides A-D (1-4, respectively), were discovered from the aerial portions of Hypericum elatoides R. Keller. Their structures were elucidated by analysis of NMR spectra, HRESIMS, quantum chemical calculations of NMR and ECD spectra, and X-ray crystallographic data. Hyperelatolides A (1) and B (2) represent the first examples of δ-lactone derivatives characterized by a (Z)-(5,5-dimethyl-2-(2-oxopropyl)cyclohexylidene)methyl moiety and a benzoyloxy group attached to the ß- and γ-positions of the δ-lactone core, respectively, while hyperelatolides C (3) and D (4) are unprecedented γ-lactone derivatives featuring substituents similar to those of 1 and 2. All compounds were tested for their inhibitory effects on NO production in LPS-activated BV-2 cells. Lactones 1 and 2 exhibited considerable antineuroinflammatory activity, with IC50 values of 5.74 ± 0.27 and 7.35 ± 0.26 µM, respectively. Moreover, the mechanistic study revealed that lactone 1 significantly suppressed nuclear factor kappa B signaling and downregulated the expression of inducible nitric oxide synthase and cyclooxygenase-2 in LPS-induced cells, which may contribute to its antineuroinflammatory activity.

RESUMO

Six undescribed C27-phytoecdysteroid derivatives, named superecdysones A-F, and ten known analogs were extracted from the whole plant of Dianthus superbus L. Their structures were identified by extensive spectroscopy, mass spectrometric methods, chemical transformations, chiral HPLC analysis, and the single-crystal X-ray diffraction analysis. Superecdysones A and B possess a tetrahydrofuran ring in the side chain and superecdysones C-E are rare phytoecdysones containing a (R)-lactic acid moiety, whereas superecdysone F is an uncommon B-ring-modified ecdysone. Notably, based on the variable temperature (from 333 K to 253 K) NMR experiments of superecdysone C, the missing carbon signals were visible at 253 K and assigned. The neuroinflammatory bioassay of all compounds were evaluated, and 22-acetyl-2-deoxyecdysone, 2-deoxy-20-hydroxyecdysone, 20-hydroxyecdysone, ecdysterone-22-O-benzoate, 20-hydroxyecdysone-20,22-O-R-ethylidene, and acetonide derivative 20-hydroxyecdysterone-20, 22-acetonide significantly suppressed the LPS-induced nitric oxide generation in microglia cells (BV-2), with IC50 values ranging from 6.9 to 23.0 µM. Structure-activity relationships were also discussed. Molecular docking simulations of the active compounds confirmed the possible mechanism of action against neuroinflammations. Furthermore, none compounds showed cytotoxicity against HepG2 and MCF-7. It is the first report about the occurrence and anti-neuroinflammatory activity of the phytoecdysteroids in the genus Dianthus. Our findings demonstrated that ecdysteroids may be used as potential anti-inflammatory drugs.

RESUMO

Rational design of low-cost and high-efficiency electrocatalysts for hydrogen evolution reaction (HER) is critical for scalable and sustainable hydrogen production from economical water-alkali splitting. Herein, density functional theory (DFT) calculations reveal that coupling NiOx and CoP could effectively boost overall HER kinetics through lowing the H2O dissociation barrier, accelerating the OH* transfer process, and providing the rapid H* migration kinetics as well as the appropriate H* energetics. Based on these findings, we successfully prepared a three-dimensional (3D) self-supported electrode of ultrathin CoP nanosheets directly grown on the surface-oxidized Ni nanotube arrays via a simple and scalable electrochemical synthesis method. As expected, such a heterostructure electrode exhibits superior alkaline HER performance with low overpotentials of 51 and 164 mV to drive the current densities of 10 and 500 mA cm-2, respectively, outperforming most of the efficient alkaline HER electrocatalysts.

RESUMO

The main aim of this study was to curate a COI barcode library of Chironomidae from the Tibetan Plateau (TP) as an essential supplement to the public database. Another aim is to evaluate the current status of the public database of Chironomidae in aspects of taxonomic coverage, geographic representation, barcode quality, and efficiency for molecular identification, the Tibetan Plateau, China. In this study, 512 individuals of Chironomidae from the TP were identified based on morphological taxonomy and barcode analysis. The metadata of public records of Chironomidae were downloaded from the BOLD, and the quality of the public barcodes was ranked using the BAGS program. The reliability of the public library for molecular identification was evaluated with the newly curated library using the BLAST method. The newly curated library comprised 159 barcode species of 54 genera, of which 58.4% of species were likely new to science. There were great gaps in the taxonomic coverage and geographic representation in the public database, and only 29.18% of barcodes were identified at the species level. The quality of the public database was of concern, with only 20% of species being determined as concordant between BINs and morphological species. The accuracy of molecular identification using the public database was poor, and about 50% of matched barcodes could be correctly identified at the species level at the identity threshold of 97%. Based on these data, some recommendations are included here for improving barcoding studies on Chironomidae. The species richness of Chironomidae from the TP is much higher than ever recorded. Barcodes from more taxonomic groups and geographic regions are urgently needed to fill the great gap in the current public database of Chironomidae. Users should take caution when public databases are adopted as reference libraries for the taxonomic assignment.

RESUMO

Since pro-inflammatory macrophages take on a critical significance in the pathophysiology of rheumatoid arthritis (RA), the therapeutics to affect macrophages may receive distinct anti-RA effects. However, the therapeutic outcomes are still significantly impeded, which is primarily due to the insufficient drug delivery at the arthritic site. In this study, the macrophage-targeting and pH stimuli-responsive nano-polyelectrolyte complexes were designed for the efficient targeted delivery of triptolide (TP/PNPs) on the arthritic site. The anionic and cationic amphiphilic copolymers, i.e., hyaluronic acid-g-vitamin E succinate (HA-VE) and the quaternized poly (ß-amino ester) (QPBAE-C18), were prepared and then characterized. The result indicated that TP/PNPs with the uniform particle size of âˆ¼ 175 nm exhibited the high drug loading capacity and storage stability based on the polymeric charge interaction, in which DLC and DEE of TP/PNPs were obtained as 11.27 ± 0.44 % and 95.23 ± 2.34 %, respectively. Mediated by the "ELVIS" effect of NPs, CD44 receptor-mediated macrophage targeting, and pH-sensitive endo/lysosomal escape under the "proton sponge" effect, TP/PNPs exhibited the enhanced cellular internalization and cytotoxicity while mitigating the inflammation of LPS-activated RAW 264.7 cells. Even after 96-hour after administration, PNPs were preferentially accumulated in the inflammatory joints in a long term. It is noteworthy that after treatment for 14 days with 100 µg/kg of TP, TP/PNPs significantly facilitated arthritic symptom remission, protected cartilage, and mitigated inflammation of antigen-induced arthritis (AIA) rats, whereas the systematic side-effects of TP were reduced. In this study, an effective drug delivery strategy was proposed for the treatment of RA.

RESUMO

Objective:To compare the clinical outcomes between anatomical locking plate, proximal humerus internal locking system (PHILOS) and anatomical locking plate combined with suture anchors in the treatment of comminuted fractures of humeral greater tuberosity.Methods:A total of 33 comminuted fractures of humeral greater tuberosity were surgically treated from October 2016 to October 2021 at Department of Orthopedics, Tongji Hospital Affiliated to Tongji University. There were 20 males and 13 females, with an age of (53.5±13.6) years. They were assigned into 3 groups according to different internal fixation techniques. Group A of 12 cases was subjected to fixation with anatomical locking plate via the deltoid approach, group B of 10 cases subjected to fixation with PHILOS via the pectoralis major and the deltoid approaches and group C of 11 cases subjected to fixation with anatomical locking plate combined with suture anchors via the deltoid approach. The operation time, intraoperative blood loss, range of shoulder motion, Constant-Murley shoulder score, visual analogue scale (VAS) and postoperative complications were compared between the 3 groups.Results:The 3 groups were comparable because there was no significant difference between them in the general clinical data ( P>0.05). The follow-up duration for all patients was (14.5±4.1) months. All fractures got united at the last follow-up. In groups A, B and C, respectively, the operation time was (57.9±7.8), (73.0±7.1) and (63.6±9.5) min, and the intraoperative blood loss (41.7±18.9), (82.0±22.9) and (46.4±13.6) mL, showing significant differences between the 3 groups ( P<0.05). The operation time and intraoperative blood loss in groups A and C were significantly less than those in group B ( P< 0.05). At the last follow-up, in groups A, B and C, respectively, the shoulder abduction was 144.0°±7.7°, 138.7°±10.7° and 148.5°±6.2°, showing significant differences between the 3 groups ( P<0.05). Group C was significantly better than group B ( P<0.05). There was no statistically significant difference in the forward flexion, external rotation, or internal rotation of the shoulder joint between the 3 groups ( P>0.05). The Constant-Murley scores in groups A, B and C, respectively, were (90.4±5.7), (86.1±6.6) and (93.1±3.4) points, showing significant differences between the 3 groups ( P<0.05). Group C was significantly better than group B ( P<0.05). The VAS scores in groups A, B and C, respectively, were 1 (0, 2), 1 (0, 2), and 1 (0, 1) point, showing insignificant differences between the 3 groups ( P>0.05). Group A had 1 case of shoulder joint stiffness and 1 case of fracture re-displacement complicated with acromial impingement syndrome, group B 1 case of shoulder joint stiffness and 3 cases of fracture re-displacement, but group C no post-operative complication. Conclusions:In the treatment of comminuted fracture of humeral greater tuberosity, all the 3 internal fixation techniques can lead to fine clinical outcomes. Conventional PHILOS may lead to relatively large trauma and a high incidence of postoperative complications. The anatomical locking plate may result in fine functional recovery of the shoulder due to advantages of less invasion, shorter operation time and fewer postoperative complications than PHILOS. The anatomical locking plate combined with suture anchors may lead to the best shoulder functional recovery and the least complications.

RESUMO

This study compared the chemical profiles, component content, dry paste yield, and pharmacological effects of samples obtained from the mixed single decoctions and the combined decoction of Gegen Qinlian Decoction(GQD), aiming to provide an experimental foundation for evaluating the equivalence of the two decocting methods and the suitability of TCM formula granules in clinical application. The same decoction process was used to prepare the combined decoction and mixed single decoctions of GQD. Ultra-performance liquid chromatography coupled with Q-Exactive Orbitrap mass spectrometry(UPLC-Q-Exactive Orbitrap MS) was employed to compare the chemical profiles between the two groups. High-performance liquid chromatography(HPLC) was used to compare the content of nine characteristic components between the two groups. Then, a delayed diarrhea mouse model induced by irinotecan was established to compare the pharmacological effects of the two groups on chemotherapy-induced diarrhea. The UPLC-Q-Exactive Orbitrap MS in ESI~+ and ESI~- modes identified 59 chemical components in the compound decoction and mixed single decoctions, which showed no obvious differences in component species. The content of baicalin and wogonoside was higher in the compound decoction, while that of puerarin, daidzein-8-C-apiosylglucoside, berberine, epiberberine, wogonin, glycyrrhizic acid, and daidzein was higher in the mixed single decoctions. Further statistical analysis revealed no significant difference in the content of the nine characteristic components between the compound decoction and the mixed single decoctions. The dry paste yield had no significant difference between the two groups. Compared with the model group, both compound decoction and mixed single decoctions alleviated the weight loss and reduced diarrhea index in mice. Both of them lowered the levels of tumor necrosis factor-α(TNF-α), interleukin-1β(IL-1β), cyclooxygenase-2(COX-2), intercellular adhesion molecule-1(ICAM-1), interleukin-10(IL-10), malondialdehyde(MDA), and nitric oxide(NO) in the colon tissue. Furthermore, they significantly increased the levels of glutathione peroxidase(GSH-Px) and superoxide dismutase(SOD). Hematoxylin-eosin(HE) staining showed that colon tissue cells were tightly arranged with clear nuclei in both groups without obvious difference. The compound decoction and mixed single decoctions showed no significant differences in chemical component species, content of nine characteristic components, dry paste yield, or the pharmacological effects on alleviating chemotherapy-induced diarrhea. The findings provide a reference for evaluating the flexibility and superiority of combined or single decocting method in the preparation of TCM decoctions or formula granules.

RESUMO

Objective: To investigate the normal process of tooth development of C57BL/6 mouse strain by using micro-CT for better understanding about the tooth development of the human being and other species. Methods: A total of 54 C57BL/6 mice were used at postnatal day 1 (P1), P3, P7, P10, P14, P21, P28, P42 and P56 (n=6 for each age group). After euthanasia, the skulls and alveolar bones (with molars) were isolated and scanned by micro-CT scanner. After three dimensional reconstruction, the developmental status of the crown and root(s) for each tooth type was examined in different views. Results: The tooth development of mice from birth to mature (P56) could be divided into three stages. The first stage was from P1 to P14, in which the crowns of all the first, second and third molars had formed, while the roots had not fully developed yet. The second stage was from ablactation (P21) to P28, in which all the roots of the molars had reached their normal length, and the apical foramens had closed. Due to the mastication and occlusal abrasion, the incisors exhibited sharp cutting edges at the buccal enamel layer, and the corresponding molars formed a pit-to-fossa articulated relationship. The third stage was from P42 to P56, in which the root canal differentiation occurred, and 1-2 canal configuration was formed in several flat roots. The development of molar roots had completed and the apexes were enlarged due to the deposition of cementum around. Conclusions: In the process of mouse tooth development, the mineralization of the cusps, followed by crown formation and roots elongation, was precisely regulated in a spatial-temporal pattern. The incisors and the molars exhibited different modes of development.

RESUMO

To investigate the factors affecting the sperm retrieval rate of microdissection testicular sperm extraction (micro-TESE) in patients with nonmosaic Klinefelter syndrome (KS), 64 patients with nonmosaic KS who underwent micro-TESE in the Center for Reproductive Medicine of Peking University Third Hospital (Beijing, China) between January 2016 and December 2017 were included in the study. Data on medical history, physical examination and laboratory examination results, and micro-TESE outcomes were collected. Patients were divided into two groups according to micro-TESE outcomes. The following factors were compared between the two groups by the Mann‒Whitney U test or Student's t-test based on the distribution (nonnormal or normal) of the factors: age, testicular size, follicle-stimulating hormone level, luteinizing hormone level, testosterone level, and anti-Müllerian hormone level. The overall success rate of sperm retrieval was 50.0%. Correlation analysis showed that testicular volume was positively correlated with testosterone level. Using a logistic regression model, age and anti-Müllerian hormone levels were found to be better predictors for the sperm retrieval rate than the other parameters.

RESUMO

Regulation of tumor vessels has become one of the most common strategies for clinical anti-tumor therapy. In recent years, studies have found that the anti-tumor effect of limotherapy, which routinely inhibits tumor angiogenesis, is not ideal and may even deteriorate the tumor microenvironment, causing tumor resistance and distal metastasis and increasing the risk of tumor metastasis and recurrence. However, the proper use of anti-angiogenic drugs can promote the normalization of tumor vessels, improve the structure and function of tumor vessels, increase the number of functional vessels in the tumor, and reduce the number of ineffective vessels. It is beneficial to promote the penetration of anti-tumor drugs into the tumor, improve the microenvironment of tumor hypoxia and immunosuppression, and enhance the anti-tumor effect. Traditional Chinese medicine(TCM) has a long history of understanding the etiology and pathogenesis of tumors and has accumulated rich experience in tumor treatment, with significant clinical advantages and broad application prospects. In this study, from the perspective of bidirectional "soothing" or "blockage" regulation of tumor vessels, the commonly used molecular targets were sorted out, and the research status of anti-tumor regulation of tumor vessels by monomer-single herb-compound(herb pair) of TCM in recent years was summarized. The research on the anti-tumor effects of TCM compounds and active ingredients by regulating tumor vessels combined with other therapies was analyzed and sorted out, so as to provide ideas for the clinical application of TCM in regulating functions and anti-tumor effects of tumor vessels.

RESUMO

The resin ethanol extract of Gegen Qinlian Decoction(GGQLD) has been found to significantly alleviate the intestinal toxicity caused by Irinotecan, but further research is needed to establish its overall quality and clinical medication standards. This study aimed to establish an HPLC characteristic fingerprint of the resin ethanol extract of GGQLD, predicted the targets and signaling pathways of its pharmacological effects based on network pharmacology, identified core compounds with pharmacological relevance, and analyzed potential quality markers(Q-markers) of the resin eluate of GGQLD for relieving Irinotecan-induced toxicity. By considering the uniqueness, measurability, and traceability of Q-markers based on the "five principles" of Q-markers and combining them with network pharmacology techniques, the overall efficacy of the resin ethanol extract of GGQLD can be characterized. Preliminary predictions suggested that the four components of puerarin, berberine, baicalin, and baicalein might serve as potential Q-markers for the resin etha-nol extract of GGQLD. This study provides a basis and references for the quality control and clinical mechanism of the resin ethanol extract of GGQLD.

RESUMO

By examining the changes in the conceptual associations between individualism-collectivism and 10 other concepts based on the Google Ngram Chinese Corpus from the 1950s to the 1990s, Hamamura et al. (2021) inferred (a) no rise in individualism; (b) continuing collectivism; and (c) no effect of modernization on individualism in contemporary China. We question the validity of these conclusions given the following issues in their research: (a) misinterpretation of statistical results; (b) improper calculation of cultural associations; and (c) inappropriate generalization of specific findings. Contrary to their original findings, our reanalysis of their data suggests that individualism has been increasingly accepted and associated with some positive (vs. negative) aspects of life (e.g., income vs. loss, richness vs. poverty) over recent decades in China. Future research should use more rigorous methods and diverse corpora to clarify and explain changes in individualism and collectivism in China.

RESUMO

Epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) have significantly improved response in all stages of patients with EGFR positive mutations in nonsmall cell lung cancer. However, the primary resistance mechanism of EGFR-TKIs has not been thoroughly revealed. Here, we described a case of a 64-year-old male with lung adenocarcinoma presented primary resistance on osimertinib combined with bevacizumab and platinum-based chemotherapy, next-generation sequencing revealed EGFR exon 21 L858R mutation and MET gene amplification. Afterward, savolitinib monotherapy was started until now, and the treatment was temporarily successful, the last follow-up clinical evaluation was near complete response, the progression-free survival has over 7 months. Our case highlights that EGFR-TKIs may be not the optimal choice for lung adenocarcinoma with primary EGFR -sensitive mutation with MET amplification simultaneously, whereas MET inhibitor alone may be an effective treatment option. In clinical practice, we should fully consider the possibility of primary resistance in EGFR-TKIs administration.
