RESUMEN

Objective:To evaluate the effect of five-element acupuncture on clinical symptoms, brain metabolism and immunoglobulin level in patients with chronic fatigue syndrome.Methods:It was a randomized controlled trial. A total of 94 patients with chronic fatigue syndrome in our hospital from January 2021 to January 2022 were selected and divided into two groups according to the random number table method, with 47 in each group. The conventional western medicine group was treated with conventional western medicine, and the five-element acupuncture group was treated with five-element acupuncture on the basis of the conventional western medicine group. Both groups were treated for 4 weeks. Before and after treatment, the serum levels of interferon-γ (IFN-γ), corticosterone (CORT), IL-2 and 5-hydroxytryptamine (5-HT) were detected by ELISA; the levels of natural killer (NK) cells, CD4 +, CD8 +, IgG and IgM were detected by flow cytometry; the whole body superconducting MRI scanner was used to scan T2 Flair, T2WI and TlWI sequences of the hippocampus, and the spectral curves and the areas under the peak of N-acetylaspartic acid (NAA), creatine (Cr) and choline (Cho) were obtained, and the ratios of Cho/Cr and NAA/Cr were calculated. the fatigue Scale-14 (FS-14) and Fatigue Severity Scale (FSS) were used to evaluate the fatigue state of the patients, and the Depression-Anxiety-Stress Scale-21 (DASS-21) and Beck Anxiety Inventory (BAI) were used to evaluate the anxiety state of the patients. Symptom Checklist 90 (SCL-90) and Somatic and Mental Health Report Score (SPHERE) were used to evaluate the quality of life of patients. And the clinical efficacy was evaluated. Results:After treatment, the levels of IgG, CD4 + and NK in the five-element acupuncture group were significantly higher than those in the conventional western medicine group ( t values were 4.76, 3.65, 6.42, respectively, P<0.01), and the level of IgM, CD8 + was significantly lower than that in the conventional western medicine group ( t values were 7.30, 4.79, P<0.01); the levels of IFN-γ, IL-2 and 5-HT in the observation group were significantly higher than those in the conventional western medicine group ( t values were 7.60, 4.05, 2.79, respectively, respectively, P<0.01), and the level of CORT was significantly lower than that in the conventional western medicine group ( t=6.72, P<0.01); the NAA/Cr levels in the left [(1.10±0.04) vs. (1.05±0.03), t=6.86] and right [(1.18±0.02) vs. (1.21±0.03), t=8.23] hippocampus of the experimental group were significantly higher than those in the conventional western medicine group ( P<0.01), and the Cho/Cr levels in the left [(1.08±0.04) vs. (1.03±0.03), t=5.70] and right [(1.17±0.02) vs. (1.20±0.03), t=5.71] hippocampus of the experimental group were significantly lower than those of the conventional western medicine group ( P<0.01). After treatment, the scores of physical fatigue, mental fatigue and FSS in the five-element acupuncture group were significantly lower than those in the conventional western medicine group ( t values were 8.08, 9.08 and 7.07, respectively, P<0.01). The scores of DASS-21, BAI, SCL-90 and SPHERE in the conventional western medicine group were significantly lower than those in the conventional western medicine group ( t values were 3.63, 5.77, 8.74, 5.92, respectively, P<0.01).The total effective rate was 95.74% (45/47) in the five-element acupuncture group and 82.98% (39/47) in the conventional western medicine group, and there was no significant difference between the two groups ( χ2=2.80, P=0.094). Conclusion:Five-elements acupuncture can improve the expression of T lymphocytes, increase the levels of immunoglobulin and NK, reduce the level of CORT, regulate the brain metabolism of NAA in the left and right hippocampus, improve the clinical symptoms and negative emotions, and improve the clinical efficacy and quality of life in patients with chronic fatigue syndrome.

RESUMEN

Objective To screen differentially expressed microRNAs(miRNAs)in plasma exosomes of active rheumatoid arthritis(RA)patients and healthy controls and conduct bioinformatics analysis for exploring the role and potential clinical application value of miRNAs in the pathogenesis of RA.Methods From January 2023 to April 2023,39 RA patients who visited the Rheumatology and Immunology Department of the Second Affiliated Hospital of Soochow University were selected as the study subjects,while 39 healthy individuals were selected as normal controls.The expression levels of miRNAs in plasma exosomes were detected by Illumina high-throughput sequencing technology,and the differentially expressed miRNAs were obtained by log2(Fold Change)absolute value>1 and P value<0.05.Six miRNAs were selected by the order from small to large P-value for bioinformatics analysis and validated using quantitative real-time fluorescence PCR(qRT-PCR).Results Compared with healthy controls,22 aberrantly expressed miRNAs were detected in plasma exosomes of RA patients,of which 4 were up-regulated and 18 were down-regulated.Among them,miR-30b-5p,miR-144-3p,miR-20a-5p,miR-223-5p,miR-425-3p,and miR-589-5p showed changed significantly.GO and KEGG enrichment analysis indicated that differentially expressed miRNAs may be involved in disease progression through regulation of signaling pathways such as TGF-β and PI3K/AKT,which were related to biological processes such as Th17 differentiation,intercellular interactions,and protein phosphorylation.The qRT-PCR validation results showed that the expression of miR-144-3p and miR-425-3p were significantly reduced in plasma exosomes of RA patients compared to healthy controls(t=3.617,3.595,all P<0.001),while the differences of miR-30b-5p,miR-223-5p,miR-589-5p,and miR-20a-5p expression were not statistically significant(t=1.956,1.331,1.662,1.861,all P>0.05).Conclusion The expression profile of plasma exosomal miRNAs changed in RA patients,which may be involved in disease progression through TGF-β and other signaling pathways.Exosome-derived miR-144-3p and miR-425-3p may be potential serological markers for RA diagnosis.

RESUMEN

Objective:To investigate the therapeutic effect of sequential therapy with butylphthalein on acute cerebral infarction and mild-to-moderate increases in middle cerebral artery blood flow in patients.Methods:The clinical data of 92 patients with acute cerebral infarction and mild-to-moderate increases in middle cerebral artery blood flow who received treatment at the Xiaogan Hospital Affiliated to Wuhan University of Science and Technology from January 2018 to October 2021 were retrospectively analyzed. These patients were divided into a study group and a control group using a random number table method. The control group was given an intravenous infusion of butylphthalein sodium chloride injection, while the study group took oral butylphthalein soft capsules after intravenous infusion of butylphthalein sodium chloride injection. The baseline data, hemodynamics, neurological function, and clinical outcomes were compared between the two groups. At 90 days after treatment, the National Institutes of Health Stroke Scale (NIHSS), the Activity of Daily Living Scale (ADL), and the modified Rankin Scale (mRS) were used to evaluate clinical outcomes. Transcranial Doppler ultrasound (TCD) examination was performed to evaluate hemodynamic changes.Results:A total of 92 patients completed all the observation indices as required, including 48 patients in the study group and 44 patients in the control group. There were no significant differences in demographics, vascular risk factors, laboratory results, NIHSS score, ADL score, or arterial hemodynamics of the diseased brain between the two groups (all P > 0.05). At 90 days after treatment, the NIHSS score in the study group was significantly lower than that in the control group [(4.00 ± 1.95) points vs. (4.91 ± 2.08) points; t =-2.16, P = 0.033]. The ADL score in the study group was significantly higher than that in the control group [(82.71 ± 9.56) points vs. (76.25 ± 11.47) points; t = 2.94, P = 0.004]. The good rate of outcomes in the study group was significantly higher than that in the control group [70.83% (34/48) vs. 50.00% (22/44); χ2 = 4.18, P = 0.041]. There were significant differences in the peak systolic velocity [(152.33 ± 9.58) cm/s vs. (157.41 ± 11.77) cm/s; t = 2.27, P = 0.025] and the mean velocity [(90.00 ± 8.30) cm/s vs. (94.45 ± 9.07) cm/s; t = -2.46, P = 0.016] of the middle cerebral artery between the study and control groups. The difference in pulsitility index between the two groups was not statistically significant [(0.97 ± 1.06) vs. (1.01 ± 1.21); t = 1.69, P = 0.093]. Compared with the poor outcome group, patients in the good outcome group had lower NIHSS and ADL scores after discharge (both P < 0.001), and the proportion of patients who received sequential therapy with butylphthalein in the good outcome group was higher [(60.70% (34/56) vs. 38.90% (14/36); χ2 = 4.18, P = 0.041]. Conclusion:Sequential therapy with butylphthalein can reduce neurological deficits, promote neurological function recovery, improve the hemodynamics of diseased blood vessels, and greatly improve daily living activities in patients with acute cerebral infarction complicated by mild to moderate increases in middle cerebral artery blood flow.

RESUMEN

Objective:To investigate the therapeutic effect of high-flow nasal cannula oxygen therapy (HFNC) and non-invasive positive pressure ventilation (NPPV) on patients with pulmonary edema caused by seawater drowning.Methods:A retrospective analysis method was used. Based on the Utstein database of emergency drowning in the First Hospital of Qinhuangdao, the clinical data of patients with seawater drowning pulmonary edema admitted to the emergency medicine department of the First Hospital of Qinhuangdao from January 1, 2019 to December 31, 2022 were collected. The patients were divided into NPPV group and HFNC group according to different ventilation methods. The general data, endotracheal intubation rate in 7 days, arterial blood gas analysis indexes [arterial partial pressure of oxygen (PaO 2), arterial partial pressure of carbon dioxide (PaCO 2), arterial oxygen saturation (SaO 2)] and hemodynamic indexes (systolic blood pressure, diastolic blood pressure, mean arterial pressure, heart rate, blood lactic acid) before and after treatment, length of stay in intensive care unit (ICU), oxygen therapy comfort of the two groups were compared. Results:A total of 54 patients were enrolled, including 21 patients in the NPPV group and 33 patients in the HFNC group. There were no significant differences in gender, age, state of consciousness and other general information between the two groups. Compared with NPPV group, the rate of endotracheal intubation in HFNC group within 7 days was significantly lower [24.2% (8/33) vs. 33.3% (7/21), P < 0.05]. Before treatment, there were no significant differences in arterial blood gas analysis and hemodynamics between the two groups. After treatment, the above indexes in both groups were significantly improved compared with those before treatment, and PaO 2, SaO 2, systolic blood pressure, diastolic blood pressure and mean arterial pressure in HFNC group were significantly higher than those in NPPV group [PaO 2 (mmHg, 1 mmHg≈0.133kPa): 93.56±6.37 vs. 82.14±6.25, SaO 2: 1.02±0.09 vs. 0.95±0.11, systolic blood pressure (mmHg): 117.37±8.43 vs. 110.42±8.38, diastolic blood pressure (mmHg): 79.43±7.61 vs. 72.21±4.32, mean arterial pressure (mmHg): 92.34±6.32 vs. 85.12±5.38], PaCO 2, heart rate and blood lactic acid were significantly lower than those in NPPV group [PaCO 2 (mmHg) : 34.26±5.63 vs. 37.24±6.22, heart rate (times/min): 73.38±7.56 vs. 86.25±5.41, blood lactic acid (mmol/L): 1.38±0.36 vs. 2.25±1.14], and the differences were statistically significant (all P < 0.05). In addition, the length of ICU stay in HFNC group was significantly shorter than that in NPPV group (days: 13.30±2.38 vs. 16.27±4.26), and the comfort rate of oxygen therapy was significantly higher than that in NPPV group [66.7% (22/33) vs. 42.8% (9/21)], with statistical significance (all P < 0.05). Conclusion:HFNC can improve the oxygenation of patients with pulmonary edema caused by seawater drowning, improve hemodynamics, reduce the rate of tracheal intubation, shorten the length of ICU stay, and improve the comfort of oxygen therapy, which has certain clinical application value.

RESUMEN

Post-amputation pain causes great suffering to amputees, but still no effective drugs are available due to its elusive mechanisms. Our previous clinical studies found that surgical removal or radiofrequency treatment of the neuroma at the axotomized nerve stump effectively relieves the phantom pain afflicting patients after amputation. This indicated an essential role of the residual nerve stump in the formation of chronic post-amputation pain (CPAP). However, the molecular mechanism by which the residual nerve stump or neuroma is involved and regulates CPAP is still a mystery. In this study, we found that nociceptors expressed the mechanosensitive ion channel TMEM63A and macrophages infiltrated into the dorsal root ganglion (DRG) neurons worked synergistically to promote CPAP. Histology and qRT-PCR showed that TMEM63A was mainly expressed in mechanical pain-producing non-peptidergic nociceptors in the DRG, and the expression of TMEM63A increased significantly both in the neuroma from amputated patients and the DRG in a mouse model of tibial nerve transfer (TNT). Behavioral tests showed that the mechanical, heat, and cold sensitivity were not affected in the Tmem63a-/- mice in the naïve state, suggesting the basal pain was not affected. In the inflammatory and post-amputation state, the mechanical allodynia but not the heat hyperalgesia or cold allodynia was significantly decreased in Tmem63a-/- mice. Further study showed that there was severe neuronal injury and macrophage infiltration in the DRG, tibial nerve, residual stump, and the neuroma-like structure of the TNT mouse model, Consistent with this, expression of the pro-inflammatory cytokines TNF-α, IL-6, and IL-1β all increased dramatically in the DRG. Interestingly, the deletion of Tmem63a significantly reduced the macrophage infiltration in the DRG but not in the tibial nerve stump. Furthermore, the ablation of macrophages significantly reduced both the expression of Tmem63a and the mechanical allodynia in the TNT mouse model, indicating an interaction between nociceptors and macrophages, and that these two factors gang up together to regulate the formation of CPAP. This provides a new insight into the mechanisms underlying CPAP and potential drug targets its treatment.

RESUMEN

Establishment of vaginal immune defenses at the mucosal interface layer through gene vaccines promise to prevent infectious diseases among females. Mucosal barriers composed of a flowing mucus hydrogel and tightly conjugated epithelial cells (ECs), which represent the main technical difficulties for vaccine development, reside in the harsh, acidic human vaginal environment. Different from frequently employed viral vectors, two types of nonviral nanocarriers were designed to concurrently overcome the barriers and induce immune responses. Differing design concepts include the charge-reversal property (DRLS) to mimic a virus that uses any cells as factories, as well as the addition of a hyaluronic acid coating (HA/RLS) to directly target dendritic cells (DCs). With a suitable size and electrostatic neutrality, these two nanoparticles penetrate a mucus hydrogel with similar diffusivity. The DRLS system expressed a higher level of the carried human papillomavirus type 16 L1 gene compared to HA/RLS in vivo. Therefore it induced more robust mucosal, cellular, and humoral immune responses. Moreover, the DLRS applied to intravaginal immunization induced high IgA levels compared with intramuscularly injected DNA (naked), indicating timely protection against pathogens at the mucus layer. These findings also offer important approaches for the design and fabrication of nonviral gene vaccines in other mucosal systems.

RESUMEN

Flavonoids such as baohuoside I and icaritin are the major active compounds in Epimedii Folium(EF)and possess excellent therapeutic effects on various diseases.Encouragingly,in 2022,icaritin soft capsules were approved to reach the market for the treatment of hepatocellular carcinoma(HCC)by National Medical Products Administration(NMPA)of China.Moreover,recent studies demonstrate that icaritin can serve as immune-modulating agent to exert anti-tumor effects.Nonetheless,both production effi-ciency and clinical applications of epimedium flavonoids have been restrained because of their low content,poor bioavailability,and unfavorable in vivo delivery efficiency.Recently,various strategies,including enzyme engineering and nanotechnology,have been developed to increase productivity and activity,improve delivery efficiency,and enhance therapeutic effects of epimedium flavonoids.In this review,the structure-activity relationship of epimedium flavonoids is described.Then,enzymatic en-gineering strategies for increasing the productivity of highly active baohuoside I and icaritin are dis-cussed.The nanomedicines for overcoming in vivo delivery barriers and improving therapeutic effects of various diseases are summarized.Finally,the challenges and an outlook on clinical translation of epi-medium flavonoids are proposed.

RESUMEN

As a ligand-dependent transcription factor,retinoid-associated orphan receptor γt(RORyt)that controls T helper(Th)17 cell differentiation and interleukin(IL)-17 expression plays a critical role in the pro-gression of several inflammatory and autoimmune conditions.An emerging novel approach to the therapy of these diseases thus involves controlling the transcriptional capacity of RORyt to decrease Th17 cell development and IL-17 production.Several RORyt inhibitors including both antagonists and inverse agonists have been discovered to regulate the transcriptional activity of RORyt by binding to orthosteric-or allosteric-binding sites in the ligand-binding domain.Some of small-molecule inhibitors have entered clinical evaluations.Therefore,in current review,the role of RORyt in Th17 regulation and Th17-related inflammatory and autoimmune diseases was highlighted.Notably,the recently developed RORyt inhibitors were summarized,with an emphasis on their optimization from lead compounds,ef-ficacy,toxicity,mechanisms of action,and clinical trials.The limitations of current development in this area were also discussed to facilitate future research.

RESUMEN

Objective:To analyze the clinical knowledge and training needs of general practitioners from subjective perception and objective assessment, and to analyze their relationship.Methods:A survey was conducted among general practitioners from community health service centers in Shanghai Changning district from September to December 2020. Based on the general practitioner competency indicator system designed by the project team, 17 clinical knowledge competency evaluation indicators were developed through expert consultation, and used for subjective perception and objective assessment of clinical knowledge and learning needs among general practitioners. The influencing factors of objective assessment scores were analyzed, and the relationship between subjective perception and objective assessment scores was analyzed using the four quadrant method.Results:A total of 136 general practitioners participated in the study with the mean age of (39.25±5.90) years, most of whom were attending physician (67.65%, 92/136) and had undergraduate education (88.20%, 122/136). The average daily application frequency score was (1.55±0.21), and the training needs score was (1.65±0.09) for 17 clinical knowledge items; the average objective evaluation score was (74.21±14.0) points. The older the age ( OR=1.25, 95% CI:1.14-1.37), the higher the educational level ( OR=2.11, 95% CI:1.57-2.83), and the longer the working years ( OR=1.16, 95% CI:1.04-1.30) were significantly correlated with the higher objective evaluation scores (all P<0.05). The objective evaluation scores of endocrine diseases such as diabetes, cerebrovascular diseases and respiratory diseases are the highest, and the daily application frequency and learning needs are high (the first quadrant); The objective evaluation scores of common orthopedic diseases, common psychological diseases, and planned immunity indicators were relatively low, but their daily application frequency and learning needs were relatively high (second quadrant). The objective evaluation scores of indicators such as common malignant tumors, common dermatology diseases and health problems, and common ENT diseases were low, and the daily application frequency and learning needs were also low (the third quadrant). The objective evaluation scores of indicators such as hospice and palliative care are relatively high, but their daily application frequency and training needs are relatively low (listed in the fourth quadrant). Conclusions:The clinical knowledge levels of general practitioners are correlated with age, education level, and years of practice. There is a certain overlap between the objective evaluation results of clinical knowledge and the frequency of knowledge usage and training needs of general practitioners, and a targeted training mechanism should be established.

RESUMEN

Objective:To construct an evaluation scale for post competence of family doctors based on knowledge-skill-management model.Methods:The evaluation dimensions and indicators for post competency of family doctors were preliminarily developed through literature review, internal group meeting and brainstorming, and in-depth interviews of experts. And 16 experts in the fields of general practice and health management were invited for 2 rounds of Delphi consultation from December 2020 to April 2021. A competency evaluation scale for family doctors based on the dimensions of knowledge, skills and management was finally constructed.Results:The age of the experts was (47.9±7.3) years with a working experience of (24.6±7.8) years. The Cronbach′s α of the questionnaires was 0.891 and the KMO was 0.844. The positive coefficients for 2 rounds of expert consultation were 100%; the familiarity level of experts was 0.86 and authority level was 0.89 in the first round consultation, and those were 0.84 and 0.90 in the second round consultation. After 2 rounds of consultation, the coordination coefficient of expert opinions in the knowledge and skill dimensions was>0.5, and that in the management dimension and overall evaluation system was>0.3.

RESUMEN

Mitochondrial myopathy is a group of multi-system diseases in which mitochondrial DNA(mtDNA)or nuclear DNA(nDNA)defects lead to structural and functional dysfunction of mitochondria.The clinical manifestations of mitochondrial myopathy are complex and varied,and the testing for mtDNA and nDNA is not widely available,so misdiagnosis or missed diagnosis is common.Chronic progressive external ophthalmoplegia(CPEO)is a common type of mitochondrial myopathy,which is characterized by blepharoptosis.Here we report a 38-year-old female with mitochondrial myopathy presented with chronic numbness and weakness of the limbs,accompanied by blepharoptosis that was recently noticed.Laboratory and head magnetic resonance imaging(MRI)examinations showed no obvious abnormalities.Muscle and nerve biopsies showed characteristic ragged red fibers(RRFs)and large aggregates of denatured mitochondria.Testing for mtDNA and nDNA showed a known mutation c.2857C>T(p.R953C)and a novel variant c.2391G>C(p.M797I)in the polymerase gamma(POLG)gene,so the patient was diagnosed as mitochondrial myopathy.Clinicians should pay more attention to long-term unexplained skeletal muscle diseases with recent onset blepharoptosis.Histopathologic examination and genetic testing are of great value in the early diagnosis and therapeutic intervention.

RESUMEN

Objective:To evaluate the efficacy and tolerability of crisaborole 2% ointment in the treatment of childhood atopic dermatitis (AD) at the early stage, and to compare the efficacy of every-other-day (Qod) regimen versus twice-a-week (Biw) regimen against recurrence in the remission stage of AD.Methods:A multicenter, randomized, open-label clinical trial was conducted. Totally, 150 children with mild to moderate AD aged 2 - < 18 years were enrolled from 6 hospitals (including Beijing Children′s Hospital, Capital Medical University, etc), and randomly divided into the Qod group (76 cases) and the Biw group (74 cases). In the acute stage of AD, both groups were treated with topical crisaborole 2% ointment on skin lesions twice a day for 2 - 4 weeks, as well as with emollients throughout the whole body. The improvement of early clinical symptoms was evaluated, and the occurrence of adverse reactions was recorded in the follow up. Once the investigator′s static global assessment (ISGA) scores decreased to 1 point or less, the patient would be enrolled into the remission stage. In the remission stage of AD, patients in the Qod group and Biw group were treated with crisaborole ointment every other day and twice a week respectively; the recurrence rate of AD in the remission stage was evaluated, as well as the severity of skin lesions, itching, life quality, and the occurrence of adverse reactions at weeks 4, 8, and 12. Statistical analysis was carried out with SPSS 23.0 software by using t test for comparisons of normally distributed continuous data between two groups, Mann-Whitney U test for non-normally distributed data, chi-square test for enumeration data, and Kaplan-Meier method for analysis of survival rates. Results:A total of 142 patients were enrolled in the modified intention-to-treat population, including 71 in the Qod group and 71 in the Biw group. In the acute stage of AD, the improvement of itching and skin lesions self-reported by the children or their family members occurred on days 1.9 (1.0, 3.0) and 2.0 (1.0, 4.1) after the application of crisaborole ointment, respectively. At the end of treatment in the acute stage, 89 children (62.7%) achieved ISGA 0/1 and successfully transferred into the remission stage. The follow-up in the remission stage was completed in 83 patients (44 in the Qod group and 39 in the Biw group). In addition, recurrence occurred in 19 (43.2%) and 12 (30.8%) patients in the Qod group and Biw group respectively, and there was no significant difference in the recurrence rate between the two groups ( χ2 = 1.36, P = 0.243) ; the average time to recurrence was 64.25 (95% CI: 53.33 - 75.17) days and 75.78 (95% CI: 65.46 - 86.10) days in the Qod group and Biw group respectively. Among the patients who were in the remission stage and had not yet experienced relapse at weeks 4, 8, and 12, there were no significant differences in the eczema area and severity index (EASI) scores, ISGA scores, pruritus numerical rating scale (NRS) scores, or quality-of-life scores between the two groups (all P > 0.05) at any time points, except for the ISGA scores at week 12 (Biw group: 0 [0, 1] point vs. Qod group: 1 [0, 1] point; Z = -2.31, P = 0.021). A total of 146 patients were enrolled in the safety set. During the study period, 70 adverse events occurred in 65 patients, with an incidence rate of 44.5%, and all were mild or moderate adverse events; 55 (37.7%) patients experienced discomfort at the medication site, which mainly referred to pain (45 cases, 30.8%) and mostly occurred in the tender and skinfold areas. Conclusions:Crisaborole 2% ointment could effectively relieve clinical symptoms in children with mild to moderate AD in the early stage, and intermittent treatment could continuously relieve clinical symptoms in the remission stage. The common adverse reaction was discomfort at the application site in the early stage of AD. There was no significant difference in the impact on AD recurrence in the remission stage between the Qod regimen and Biw regimen.

RESUMEN

Objective:To summarize the trend of disease burden of esophageal cancer in 4 countries with high incidence of esophageal cancer and analyse the proportion of death attribution of three common risk factors, which helps to provide reference for the prevention and control of esophageal cancer.Methods:Based on the 2019 Global Burden of Disease Study (GBD2019) database and visualization platform, the absolute number and age-standardized rates of incidence, mortality and disability adjusted life years (DALY) of esophageal cancer in 4 countries with high incidence of esophageal cancer (China, Iran, Russia and South Africa) from 1990 to 2019 were described. The Joinpoint regression model was used for time trend analysis, and the annual percentage change (APC) and average annual percentage change (AAPC) of age-standardized incidence, age-standardized mortality, and age-standardized DALY rate of esophageal cancer were calculated. The proportion of death attribution of three common risk factors (smoking, alcohol consumption and low fruit intake) in 2019 was compared, and the differences in the population attributable fraction (PAF) for risk factors globally and in 4 countries were analyzed. The incidence and mortality of esophageal cancer under different socio-demographic index (SDI) were analyzed by drawing fitting curves.Results:From 1990 to 2019, the age-standardized incidence, mortality and DALY rates of esophageal cancer showed an overall decreasing trend globally and in 4 countries with high incidence of esophageal cancer. The age-standardized incidence rate of esophageal cancer in China decreased from 21.0/100 000 to 13.9/100 000 (AAPC = -1.4%, 95% CI -1.3% - -1.1%), the age-standardized mortality rate decreased from 22.1/100 000 to 13.1/100 000 (AAPC = -1.8%, 95% CI -1.9% - -1.7%), and the age-standardized DALY rate decreased from 507.0/100 000 to 227.5/100 000 (AAPC = -2.1%, 95% CI -2.2% - -1.9%). These rates in China had been decreasing at a much faster rate than the other 3 countries. Both Chinese men and Russian men had higher rates of esophageal cancer deaths due to smoking and alcohol consumption than the global average (PAF smoking: 59.2%, 56.7% vs. 51.2%; PAF alcohol consumption: 29.7%, 38.3% vs. 28.4%). The proportion of alcohol-related esophageal cancer deaths in Russian women was higher than the global average for women (PAF: 14.9% vs. 7.3%). Attributing low fruit intake to esophageal cancer deaths in South African men and women were higher than the global average for men and women (PAF men: 20.8% vs. 9.8%; PAF women: 21.3% vs. 11.7%). The age-standardized incidence and mortality rates in China and South Africa were consistently higher than would be expected for the same level of SDI, while those in Iran were consistently lower than would be expected, and Russia was broadly in line with expectation. Conclusions:Although the disease burden of countries with high incidence of esophageal cancer in the world has been effectively controlled, the disease burden of esophageal cancer in China is still higher than that in other countries. Targeted prevention measures should be made according to the epidemiological characteristics of esophageal cancer in Chinese population.

RESUMEN

The paradox of increasing health needs and limited health resources prompted a change in the traditional concept of disease prevention and control, and the concept of proactive health has emerged. Proactive health aimed to prevent and control disease and improve the body's immunity by using controlled methods and means to activate the body's self-healing ability and to identify foreign harmful substances as well as damage factors and tumor cells that the body itself may produce while giving full play to individual initiative. With the continuous development of science, people could maintain and improve their immune system from many aspects, which could be roughly divided into nonpharmaceutical interventions and pharmaceutical interventions. Nonpharmacological interventions included changing lifestyles and habits, adjusting the nutritional structure and intake of food, regulating mindsets and emotions, and improving the living and working environment, etc. This review systematically elaborated on the functions and molecular mechanisms of nutrition, exercise, sleep, and emotion in regulating immunity, to provide some scientific evidence and theoretical support for proactive health.

RESUMEN

OBJECTIVE@#To investigate the molecular mechanisms underlying the effect of baicalin on prostate cancer (PCa) progression both in vivo and in vitro.@*METHODS@#The in situ PCa stem cells (PCSCs)-injected xenograft tumor models were established in BALB/c nude mice. Tumor volume and weight were respectively checked after baicalin (100 mg/kg) treatment. Hematoxylin-eosin (HE) staining was used to observe the growth arrest and cell necrosis. mRNA expression levels of acetaldehyde dehydrogenase 1 (ALDH1), CD44, CD133 and Notch1 were determined by reverse transcription-polymerase chain reaction. Protein expression levels of ALDH1, CD44, CD133, Notch1, nuclear factor κB (NF-κB) P65 and NF-κB p-P65 were detected by Western blot. Expression and subcellular location of ALDH1, CD44, CD133, Notch1 and NF-κB p65 were detected by immunofluorescence analysis. In vitro, cell cycle distribution and cell apoptosis of PC3 PCSCs was assessed by flow cytometry after baicalin (125 µmol/L) treatment. The migration and invasion abilities of PCSCs were assessed using Transwell assays. Transmission electron microscopy scanning was utilized to observe the structure and autophagosome formation of baicalin-treated PCSCs. In addition, PCSCs were infected with lentiviruses expressing human Notch1.@*RESULTS@#Compared with the control group, the tumor volume and weight were notably reduced in mice treated with 100 mg/kg baicalin (P<0.05 or P<0.01). Histopathological analysis showed that baicalin treatment significantly inhibited cell proliferation and promoted cell apoptosis. Furthermore, baicalin treatment reduced mRNA and protein expression levels of CD44, CD133, ALDH1, and Notch1 as well as the protein expression of NF-κB p-P65 in the xenograft tumor (P<0.01). In vitro, the cell proliferation of PCSCs was significantly attenuated after treatment with 125 µmol/L baicalin for 72 h (P<0.01). The cell migration and invasion rates were decreased following treatment with baicalin for 48 and 72 h (P<0.01). Baicalin notably induced cell apoptosis and seriously damaged the structure of PCSCs. The mRNA and protein expressions of CD133, CD44, ALDH1 and Notch1 in PCSCs were significantly downregulated following baicalin treatment (P<0.01). Importantly, the inhibitory effects of baicalin on PCa progression and stemness were reversed by Notch1 overexpression (P<0.05 or P<0.01).@*CONCLUSION@#Mechanistically, baicalin exhibited a potential therapeutic effect on PCa via inhibiting the Notch1/NF-κB signaling pathway and its mediated cancer stemness.
