RESUMEN

Objective@#The scientific community knows little about the long-term influence of coronavirus disease 2019 (COVID-19) on olfactory dysfunction (OD). With the COVID-19 pandemic ongoing worldwide, the risk of imported cases remains high. In China, it is necessary to understand OD in imported cases.@*Methods@#A prospective follow-up design was adopted. A total of 11 self-reported patients with COVID-19 and OD from Xi'an No. 8 Hospital were followed between August 19, 2021, and December 12, 2021. Demographics, clinical characteristics, laboratory and radiological findings, and treatment outcomes were analyzed at admission. We surveyed the patients via telephone for recurrence and sequelae at the 1-, 6-, and 12-month follow-up.@*Results@#Eleven patients with OD were enrolled; of these, 54.5% (6/11) had hyposmia and 45.5% (5/11) had anosmia. 63.6% (7/11) reported OD before or on the day of admission as their initial symptom; of these, 42.9% (3/7) described OD as the only symptom. All patients in the study received combined treatment with traditional Chinese medicine and Western medicine, and 72.7% (8/11) had partially or fully recovered at discharge. In terms of OD recovery at the 12-month follow-up, 45.5% (5/11) reported at least one sequela, 81.8% (9/11) had recovered completely, 18.2% (2/11) had recovered partially, and there were no recurrent cases.@*Conclusions@#Our data revealed that OD frequently presented as the initial or even the only symptom among imported cases. Most OD improvements occurred in the first 2 weeks after onset, and patients with COVID-19 and OD had favorable treatment outcomes during long-term follow-up. A better understanding of the pathogenesis and appropriate treatment of OD is needed to guide clinicians in the care of these patients.

RESUMEN

Breast cancer is a major chronic disease threatening women's health. It has topped the global cancers as the diagnosed cases outnumbered lung cancer patients in 2020. Internal damage due to the seven emotions is an important cause of breast cancer and the disorders of hypothalamic-pituitary-adrenal(HPA) axis and endocrine system and the abnormal immune defense mechanism in response to psychological stress all affect the occurrence and development of breast cancer. It is noteworthy that the theory of seven emotions in traditional Chinese medicine and the psychological stress theory of modern medicine have something in common in some aspects. Therefore, this study explored the correlation between internal damage due to the seven emotions and psychological stress and analyzed the molecular biological mechanisms of psychological stress influencing breast cancer from the perspective of modern medicine, which is helpful to reasonably prevent breast cancer and other related tumors and improve the prognosis of breast cancer patients through emotion regulation.

RESUMEN

Objective:To observe the effect of Ginseng Radix et Rhizoma, Notoginseng Radix et Rhizoma, and Chuanxiong Rhizoma extract (GNC) on mitochondrial oxidative stress in hydrogen peroxide (H<sub>2</sub>O<sub>2</sub>)-induced aging of human umbilical vein endothelial cells (HUVECs), and explore the therapeutic mechanism of GNC on aging HUVECs. Method:The HUVECs were classified into the control group (control), H<sub>2</sub>O<sub>2</sub> model group (H<sub>2</sub>O<sub>2</sub>), H<sub>2</sub>O<sub>2</sub> + DMSO group (DMSO, 1 mL·L<sup>-1</sup>), resveratrol group (Resv, 8 μmol·L<sup>-1</sup>), and low- (200 mg·L<sup>-1</sup>), medium- (300 mg·L<sup>-1</sup>), and high-dose (400 mg·L<sup>-1</sup>) GNC (GNC-L, GNC-M, and GNC-H) groups. Except control group and H<sub>2</sub>O<sub>2</sub> group, the other groups were intervened with corresponding agents. Subsequently, 300 μmol·L<sup>-1</sup> H<sub>2</sub>O<sub>2</sub> was given to other groups except the control group for 4 h to induce aging, and then the cells were cultured in normal media for 24 h. The aging degree, cell cycle, and mitochondrial reactive oxygen species (mtROS) level were determined by SA-<italic>β</italic>-galactosidase (SA-<italic>β</italic>-Gal) staining, flow cytometry, and MitoSox red fluorescence staining, respectively. JC-10 was used as a fluorescent probe to detect the changes in mitochondrial membrane potential, and Western blot was performed to detect the expression of manganese superoxide dismutase (MnSOD) and p-p66 proteins. Result:The SA-<italic>β</italic>-gal staining results showed that H<sub>2</sub>O<sub>2</sub> group had increased blue-stained cells compared with other groups (<italic>P</italic><0.01). Compared with those in the control group, the ratio of G<sub>0</sub>/G<sub>1</sub> phase cells significantly increased (<italic>P</italic><0.05) and that of G<sub>2</sub>/M phase cells decreased (<italic>P</italic><0.05) in the H<sub>2</sub>O<sub>2</sub> group. Compared with those in the H<sub>2</sub>O<sub>2</sub> group, the proportion of G<sub>0</sub>/G<sub>1</sub> cells decreased (<italic>P</italic><0.05) while that of G<sub>2</sub>/M cells increased (<italic>P</italic><0.05) in GNC-H groups and Resv group. The fluorescence staining for determining mitochondrial ROS level showed that the H<sub>2</sub>O<sub>2</sub> group had weakened fluorescence intensity than the control, GNC-H, and GNC-M groups (<italic>P</italic><0.05). The mitochondrial membrane potential fluorescence intensity of the H<sub>2</sub>O<sub>2</sub> group was weaker than that of the control, GNC-H, GNC-M, and GNC-L groups (<italic>P</italic><0.01), as well as the Resv group (<italic>P</italic><0.05). Western blot showed that the protein level of MnSOD was significantly lower in the H<sub>2</sub>O<sub>2</sub> group than in the control, GNS-H, and GNS-M groups (<italic>P</italic><0.05), whereas the protein level of p-p66 showed an opposite trend (<italic>P</italic><0.01), indicating that the medication can alleviate the intracellular mitochondrial oxidative stress. Conclusion:GNC can delay the H<sub>2</sub>O<sub>2</sub>-induced aging of vascular endothelial cells. The GNC intervention significantly regulated the mitochondrial ROS, mitochondrial membrane potential, and related proteins MnSOD and p-p66 to alleviate oxidative stress. Chinese medicinal materials may delay the aging of vascular endothelial cells by inhibiting mitochondrial oxidative stress.

RESUMEN

To investigate the mechanism of Huanglian Wendan Decoction in intervening impaired glucose tolerance( IGT) rat insulin resistance( IR) based on the pyroptosis pathway of liver cells. The IGT rat model was established by high-fat diet( 20 weeks) combined with high temperature,humidity environment and inactive lifestyle. The experiment was divided into blank group,model group,metformin hydrochloride group( positive group)( 0. 05 g·kg~(-1)·d~(-1)) and Huanglian Wendan Decoction group( 7. 8 g·kg~(-1)·d~(-1)). After continuous intragastric administration for 4 weeks,the body weight,body length and abdominal circumferences of all the rats were measured,the Lee' s obesity indexes was calculated,and the levels of fasting plasma glucose( FPG) and 2-hour plasma glucose( 2 hPG) in each group were measured. Serum insulin levels( FINS) and tumour necrosis factor-α( TNF-α) levels were detected by ELISA,and insulin sensitivity index( ISI) and insulin resistance index( IRI) values were calculated. The expressions of cysteinyl aspartate specific proteinase-1( caspase-1),gasdermin D( GSDMD),interleukin-1β( IL-1β) and interleukin-18( IL-18) m RNA and proteins in liver tissues were detected by Real-time PCR and Western blot. Immunofluorescence was used to detect the expressions of caspase-1 and GSDMD protein in liver tissues. Huanglian Wendan Decoction could effectively reduce the weight of model rats,improve abdominal obesity,FINS,IRI and ISI indexes and correct 2 hPG levels. Compared with blank group,TNF-α levels in serum and caspase-1,GSDMD,IL-1β and IL-18 expressions in liver tissue of model control group were increased significantly. Huanglian Wendan Decoction could effectively reduce TNF-α level in serum,regulate the expressions of caspase-1,GSDMD,IL-1β and IL-18 genes and proteins in liver tissues of IGT rats. The above results showed that the occurrence and development of " obesity-IR-abnormal glucose metabolism-type 2 diabetes mellitus" was closely related to inflammatory response and the classical pyroptosis pathway mediated by caspase-1/GSDMD. The mechanism of Huanglian Wendan Decoction in improving IR may be correlated with reduction of the level of inflammatory factors and the alleviation of the state of pyroptosis,and thus reverse the course of IGT.

RESUMEN

This study investigated the mechanism of improving impaired glucose tolerance(IGT) of rats by Huanglian Wendan Decoction from the perspective of the skeletal muscle Nod-like receptor protein 3(NLRP3)/cysteinyl aspartate specific proteinase-1(caspase-1)/interleukin-1β(IL-1β), interleukin-18(IL-18) pathway. Healthy male SD rats were fed with the diet containing 45% fat for 20 weeks, accompanied by a high-temperature and high-humidity environment and an inactive lifestyle, for the establishment of the IGT rat model. The rats were divided into the blank control group, model control group, metformin hydrochloride group(positive drug group, 0.05 g·kg~(-1)·d~(-1)) and Huanglian Wendan Decoction group(7.8 g·kg~(-1)·d~(-1)). After continuous intragastric administration for 4 weeks, the obesity and glycemic indexes of all the rats were measured. The fasting serum insulin(FINS) level was determined by ELISA, with the insulin sensitivity index(ISI) and insulin resistance index(IRI) calculated. The mRNA and protein expression le-vels of nuclear factor kappaB(NF-κB), NLRP3, caspase-1, IL-1β and IL-18 in skeletal muscle tissue were detected by real-time polymerase chain reaction(PCR), Western blot and immunofluorescence. Compared with the blank control group, the model control group witnessed significantly increased mRNA and protein expression of NF-κB, NLRP3, caspase-1, IL-1β and IL-18. As revealed by the comparison with the model control group, Huanglian Wendan Decoction could effectively regulate the obesity status, reduce body weight, correct the abnormal levels of 2-hour plasma glucose(2 hPG), insulin resistance index(IRI), insulin sensitivity index(ISI), and lower the mRNA and protein expression of NF-κB, NLRP3, caspase-1, IL-1β and IL-18 in the skeletal muscle tissue of IGT rats. Combined with previous studies, the above results showed that the occurrence and development of IGT was closely related to inflammatory response and the classic pyroptosis pathway in skeletal muscle, such as NLRP3/caspase-1/IL-1β, IL-18. It is inferred that the mechanism of Huanglian Wendan Decoction was to alleviate insulin resistance(IR) and then reverse the course of IGT lies in the regulation of the abnormal insulin receptor signaling pathway based on the NLRP3 inflammasome pathway.

RESUMEN

Inhibition of bitterness is a significant measure to improve the compliance and clinical efficacy of traditional Chinese medicine(TCM) decoction. According to the characteristics of TCM decoction, such as high dispersion of bitterness components, multi-component bitterness superposition and strong instantaneous stimulation, the research group put forward a new strategy to inhibit bitterness in the early stage based on the self-assembly characteristics of amphiphilic substances in aqueous solution, in order to reduce the distribution of bitterness components in real solution and achieve the purpose of bitter-masking. It was found that the bitter-masking effect of amphiphilic substances was different on the bitter compounds of various structures. Therefore, it was speculated that there might be a certain relationship between the bitter inhibition effect and the substrate structure. In this paper, the interaction between mPEG-PLLA and five bitter alkaloids(bamatine, jatrorrhizine, berberine, epiberberine and coptisine) in Coptidis Rhizoma was studied to explore the effect of substrate structure on the inhibition of bitterness. The sensory test of volunteers was used to determine the bitter-masking effect of mPEG-PLLA on the decoction of Coptidis Rhizoma and its main bitter alkaloids. The molecular docking and molecular force field were applied to locate the bitter groups and the bitter-masking parts. The relationship between the bitter strength and the structure was analyzed by the surface electrostatic potential of the bitter alkaloids, and the correlation between the bitter-masking effect and the structural parameters of the bitter components was explored by factor analysis, so as to clarify the structure-activity relationship of mPEG-PLLA in masking the bitterness of coptis alkaloids. It was found that mPEG-PLLA had significant taste masking effect on the decoction of Coptidis Rhizoma and five alkaloids. The masking effect was obviously related to the structure of different alkaloids: the effect increased with the increase of the number of hydrogen donors, rotatable bonds, molecular weight, and hydrophobicity, and decreased with the increase of surface electrostatic potential, electrophilicity and binding energy with bitter receptors. In this study, the influence of alkaloid structure of Coptidis Rhizoma on the butter-masking effect of mPEG-PLLA was preliminarily elucidated, providing a scientific basis for better exerting the bitter-masking effect of amphiphilic block copolymers.

RESUMEN

Objective: To study the potential anti-inflammatory active ingredient of Chinese herbal Polygoni Cuspidati Rhizoma et Radix. Method: The inflammatory model of peritoneal macrophages (RAW264.7 cells) induced by lipopolysaccharide (LPS) in mice was used to screen out the anti-inflammatory activity of 95% ethanol extract of Polygoni Cuspidati Rhizoma et Radix and its macroporous resin elution site (30%, 60%, 95% ethanol eluting site). The characteristic fingerprints were established by ultra-performance liquid chromatography coupled with quadrupole time-of-flight mass spectrometry (UPLC-Q-TOF/MS) technology, and then partial least squares method (partial least squares, PLS) was used to study the spectrum-effect relationship between the peak area of the characteristic components and the inhibition rate of nitric oxide (NO), and potential anti-inflammatory active ingredients were identified according to variable important in projection (VIP). Result: The ethanol extract macroporous resin 60% ethanol elution site of Polygoni Cuspidati Rhizoma et Radix had the strongest inhibition ability of nitric oxide formation, with a certain dose-dependent relationship. The study of spectrum-effect relationship showed that 3 components had potential anti-inflammatory activity, namely Emodin-8-O-β-D-glucoside (E-8-G), Emodin-1-O-β-D-giucoside, and Emodin-8-O-(6'-O-malonyl)-glucoside. In addition, the anti-inflammatory activity of E-8-G was further validated at the cell level through molecular docking analysis. Conclusion: Three potential anti-inflammatory active ingredients were found base on the spectrum-effect relationship. This study strategy is helpful to find the active ingredients (group) of traditional Chinese medicine, and provides new research ideas and methods for studying the material basis of Chinese herbal medicine.

RESUMEN

Ellagic acid is ubiquitous in plants and is considered as a potential candidate for antioxidant and antineoplastic drugs. However, ellagic acid has poor solubility and precipitates easily even after initial solubilization. Improvement of its bioavailability has been a concern of pharmaceutical industry. It was found that storage in Sanlejiang oral liquid at low temperature keeps its stability. Ellagic acid is anomalous in a way that is easily soluble at low temperatures but precipitates at high temperatures. In order to reveal the mechanism of this phenomenon and develop precipitation prevention and control strategies, ellagic acid in Sanlejiang oral liquid was stored at high, medium and low temperatures for three months. The changes of composition and phase state of the whole system during storage were systematically tracked and studied by means of precipitation amount or morphology, HPLC chemical profile of supernatant versus precipitates, and comprehensive characterization of physical phase state. The results show that the amount of precipitation at low temperature is only 1/3 of that at normal room temperature. As the temperature rises, the sedimentation increases sharply. HPLC analyses of supernatant versus precipitates revealed that ellagic acid precipitation originated from two ways: chemical degradation and physical deposition. The chemical sedimentation is related to the hydrolysis of tannins under acidic condition, forming chebulagic acid and corilagin. Physical sedimentation is related to the decrease of the association degree and viscosity of polyphenol colloids when temperature rises. This study elucidated the stability mechanism of ellagic acid in liquid preparations of TCM, and provided the mechanistic basis for efficient utilization and solution prepartion of ellagic acid.

RESUMEN

Allergic asthma is thought to arise from an imbalance of immune regulation, which is characterized by the production of large quantities of IgE antibodies by B cells and a decrease of the interferon-γ/interleukin-4 (Th1/Th2) ratio. Certain immunomodulatory components and Chinese herbal formulae have been used in traditional herbal medicine for thousands of years. However, there are few studies performing evidence-based Chinese medicine (CM) research on the mechanisms and effificacy of these drugs in allergic asthma. This review aims to explore the roles of Chinese herbal formulae and herb-derived compounds in experimental research models of allergic asthma. We screened published modern CM research results on the experimental effects of Chinese herbal formulae and herb-derived bioactive compounds for allergic asthma and their possible underlying mechanisms in English language articles from the PubMed and the Google Scholar databases with the keywords allergic asthma, experimental model and Chinese herbal medicine. We found 22 Chinese herb species and 31 herb-derived anti-asthmatic compounds as well as 12 Chinese herbal formulae which showed a reduction of airway hyperresponsiveness, allergen-specifific immunoglobulin E, inflflammatory cell infifiltration and a regulation of Th1 and Th2 cytokines in vivo, in vitro and ex vivo, respectively. Chinese herbal formulae and herbderived bioactive compounds exhibit immunomodulatory, anti-inflflammatory and anti-asthma activities in different experimental models and their various mechanisms of action are being investigated in modern CM research with genomics, proteomics and metabolomics technologies, which will lead to a new era in the development of new drug discovery for allergic asthma in CM.

RESUMEN

To study the protective effects of Wuzi Yanzong recipe on testis germ cell apoptosis in natural ageing rats through endoplasmic reticulum stress (ERS), 16-month-old male SPF grade SD rats were randomly divided into three groups: ageing model group, and low and high-dose Wuzi Yanzong recipe groups (WZ, 1 and 4 g·kg⁻¹), with 10 rats in each group. In addition, 2-month-old SD male rats were used as adult control group. The ageing model group and the adult control group were fed with normal diet for 4 months. WZ groups were given the medicated feed for 4 months. After fasting for 12 hours, the rats were put to death. Then, the testes were immediately collected. The change of testicular tissue morphology was observed by HE staining. The expression levels of ER stress-related proteins GRP78, p-PERK, p-eif2, ATF4, p-IRE1, XBP1, ATF6 and apoptosis-related proteins CHOP, caspase12 and p-JNK in testes were detected by Western blot. Compared with the ageing model group, Wuzi Yanzong recipe alleviated the morphological changes of testicular tissue. Western blot results showed that Wuzi Yanzong recipe significantly increased the expression levels of endoplasmic reticulum stress-related proteins GRP78, p-PERK, p-eif2, ATF4, p-IRE1, XBP1, ATF6 and significantly decreased the expression levels of endoplasmic reticulum-induced apoptosis-related proteins CHOP, caspase 12 and p-JNK. In conclusion, Wuzi Yanzong recipe can alleviate the ageing-related apoptosis of testicular germ cells in natural ageing rats by regulating endoplasmic reticulum stress.

RESUMEN

Glutamine is the most abundant amino acid found in plasma and cells. It is the preferred fuel for enterocytes in the small intestine, macrophages, and lymphocytes. After serious burn, increased requirement of glutamine by the gastrointestinal tract, kidney and lymphocytes, and relatively insufficient self synthesis likely contribute to the rapid decline of glutamine in circulation and cells. Glutamine supplementation can not only protect intestinal mucosa, maintain normal intestinal barrier function, reduce bacterial translocation, and enhance the intestinal immune function, but also increase the number of lymphocytes, enhance the phagocytic function of macrophage, promote the synthesis of immunoglobulin, and reduce the body′s inflammatory response, so as to enhance the immune function. Therefore, glutamine supplementation can improve and enhance the immune function, reduce complications and promote the prognosis of severely burned patients.

RESUMEN

<p><b>Background</b>High platelet reactivity (HPR) during clopidogrel treatment predicts postpercutaneous coronary intervention (PCI) ischemic events strongly and independently. Tongxinluo capsules (TCs) are a traditional Chinese medicine formulation used as antiplatelet treatment. However, its efficacy against HPR is not known. The aim of the present study was to evaluate the effects of TCs in acute coronary syndrome (ACS) patients with HPR.</p><p><b>Methods</b>This multicenter, randomized, double-blind, placebo-controlled study prospectively analyzed 136 ACS patients with HPR who underwent PCI. The patients were enrolled from November 2013 to May 2014 and randomized to receive placebo or TCs in addition to standard dual antiplatelet therapy (DAPT) with aspirin and clopidogrel. The primary end points were the prevalence of HPR at 30 days and the mean change in P2Yreaction units (PRUs) between baseline and 30 days. Survival curves were constructed with Kaplan-Meier estimates and compared by log-rank tests between the two groups.</p><p><b>Results</b>Both groups had a significantly reduced prevalence of HPR at 30 days versus baseline, but the TC group, compared with the placebo group, had greater reduction (15.8% vs. 24.8%, P = 0.013), especially among patients with one cytochrome P450 2C19 loss of function (LOF) allele (χ= 2.931, P = 0.047). The TC group also had a lower prevalence of HPR (33.3% vs. 54.2%, t = 5.284, P = 0.022) and superior performance in light transmittance aggregometry and higher levels of high-sensitivity C-reactive protein (hsCRP), but the composite prevalence of ischemic events did not differ significantly (χ= 1.587, P = 0.208).</p><p><b>Conclusions</b>In addition to standard DAPT with aspirin and clopidogrel, TCs further reduce PRU and hsCRP levels, especially in patients carrying only one LOF allele. The data suggest that TCs could be used in combination therapy for ACS patients with HPR undergoing PCI.</p>

RESUMEN

Objective To investigate the expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) after cerebral infarction and treatment with curcumin combined with electroacupuncture.Methods Middle cerebral artery occlusion was successfully introduced to simulate cerebral infarction in 60 healthy,male Wistar rats.They were then randomly divided into a control group,an electroacupuncture group,a curcumin group and a curcumin combined with electroacupuncture group (the observation group),each of 15.After the modeling,the four groups were given the planned interventions for 2 weeks,with the control group receiving no intervention.All of the rats were sacrificed after neurobehavioral scoring and immunological staining of brain tissue from the infarction area was used to detect the expression of BDNF and NGF.Results The average Bederson score in the observation group was significantly lower than those of the other groups.Cells expressing BDNF and NGF were significantly more numerous in the observation group than in the other three groups.Conclusion Curcumin combined with electroacupuncture can significantly improve the expression of BDNF and NGF in the infarcted area,and this may play a neuroprotective role.

RESUMEN

Gene editing is a kind of technologies that makes precise modification to the genome. It can be used to knock out/in and replace the specific DNA fragment, and make accurate gene editing on the genome level. The essence of the technique is the DNA sequence change with use of non homologous end link repair and homologous recombination repair, combined with specific DNA target recognition and endonuclease.This technology has wide range of development prospects and high application value in terms of scientific research, agriculture, medical treatment and other fields. In the field of gene therapy, gene editing technology has achieved cross-time success in cancers such as leukemia, genetic disorders such as hemophilia, thalassemia, multiple muscle nutritional disorders and retrovirus associated infectious diseases such as AIDS and other diseases. The preparation work for new experimental methods and animal models combined with gene editing technology is under rapid development and improvement. Laboratories around the world have also applied gene editing technique in prevention of malaria, organ transplantation, biological pharmaceuticals, agricultural breeding improvement, resurrection of extinct species, and other research areas. This paper summarizes the application and development status of gene editing technique in the above fields, and also preliminarily explores the potential application prospect of the technology in the field of traditional Chinese medicine, and discusses the present controversy and thoughts.

RESUMEN

Objective To investigate the effect of acupuncture on gap junction protein Cx43 expression in the hippocampal region in ischemia/reperfusion rats.Methods Wistar rats were randomized into normal, model, non-point acupuncture and acupuncture groups. A rat model of focal cerebral ischemia/reperfusion was made by modified middle cerebral artery thread occlusion. The model, non-point acupuncture and acupuncture groups were separately divide into four subgroups: 30, 60, 180 and 360 min ischemia/reperfusion, 10 rats each. The middle and lateral lines of vertex were given electroacupuncture in the acupuncture group of rats. A subcostal fixed point 10 mm above the iliac crest on the affect side was selected as an acupuncture point in the non-point acupuncture group. The model group was not treated. Cx43 protein expression was determined by an immunohistochemical method.Results There was a statistically significant difference in the behavior disorder (Bederson’s) score between the acupuncture group and the non-point acupuncture or model group after different times of cerebral ischemia/ reperfusion (P<0.05). There was a statistically significant difference in hippocampal Cx43 content between model, acupuncture or non-point acupuncture group and the normal group and between the acupuncture group and the model or non-point acupuncture group after different times of cerebral ischemia/reperfusion (P<0.05).Conclusions Acupuncture can inhibit the overexpression of Cx43, intervene in cerebral ischemia-reperfusion injury and produce a neuroprotective effect in ischemic brain injury.
