Preliminary study on the mechanism of halofuginone inhibiting the activity of HepG2 cells / 药学学报

This study aimed to investigate halofuginone's inhibitory effect and mechanism on the activity of hepatocellular carcinoma cells. HepG2 cells were used to detect the effects of halofuginone. After treatment, cell activity, cell migration, cell cycle, and cell apoptosis were detected by CCK-8, transwell, and flow cytometry, respectively. The expression levels of growth and metabolism-related factors such as citrate synthase (CS), ketoglutarate dehydrogenase (OGDH), and isocitrate deoxygenase (IDH) were detected by real-time quantitative PCR and Western blot. Compared with the control group, the activity of HepG2 cells was significantly inhibited by halofuginone (P < 0.01), the migration rate of HepG2 cells was decreased (P < 0.01), the apoptosis of HepG2 cells was induced (P < 0.01), and the cell cycle was arrested in S phase (P < 0.01). The expression levels of tricarboxylic acid key enzymes CS, IDH3, and OGDH were up-regulated, the expression level of isocitrate dehydrogenase isoenzymes IDH1 and IDH2 were down-regulation. In conclusion, halofuginone can inhibit the proliferation and migration of HepG2 cells and promote apoptosis in a dose-dependent manner, which may be due to the promotion of the aerobic metabolism of cells.

The role of glucose metabolism reprogramming and its targeted therapeutic agents in inflammation-related diseases / 药学学报

Cells undergo glucose metabolism reprogramming under the influence of the inflammatory microenvironment, changing their primary mode of energy supply from oxidative phosphorylation to aerobic glycolysis. This process is involved in all stages of inflammation-related diseases development. Glucose metabolism reprogramming not only changes the metabolic pattern of individual cells, but also disrupts the metabolic homeostasis of the body microenvironment, which further promotes aerobic glycolysis and provides favourable conditions for the malignant progression of inflammation-related diseases. The metabolic enzymes, transporter proteins, and metabolites of aerobic glycolysis are all key signalling molecules, and drugs can inhibit aerobic glycolysis by targeting these specific key molecules to exert therapeutic effects. This paper reviews the impact of glucose metabolism reprogramming on the development of inflammation-related diseases such as inflammation-related tumours, rheumatoid arthritis and Alzheimer's disease, and the therapeutic effects of drugs targeting glucose metabolism reprogramming on these diseases.

In vivo studies could not confirm in vitro prophylactic synergism between Moringa essential oil and Lactobacillus reuteri (MT180537)

Abstract Aerobic vaginitis (AV) is a recently defined vaginal recurring infection, which is treated with antibiotics. However, excessive and prolonged use of antibiotics disrupts healthy vaginal microflora and leads to the emergence of antibiotic resistance among pathogens. This situation has directed researchers to explore alternative antimicrobials. The current study describes in vitro and in vivo antimicrobial efficacy and pharmaceutical interactions between plant essential oils (EOs) and five lactic acid bacteria (LABs), isolated from the healthy vagina, against E. faecalis, one of the major etiological agents of AV. In vitro experiments confirm good antimicrobial activity of both plant EOs and cell free supernatant (CFS) from LABs. Based on high antimicrobial efficacy, Moringa essential oil (MO) was selected to determine its nature of interaction with CFS of five LAB strains. Synergism was recorded between MO and CFS of L. reuteri (MT180537). To validate in vitro findings, prophylactic responses of individual and synergistic application of MO and L. reuteri (MT180537) were evaluated in an E. faecalis (MW051601) induced AV murine model. The prophylactic efficacy was evidenced by a reduction in intensity of clinical symptoms, E. faecalis (MW051601) count per vaginal tissue along with a reduction in AV associated changes in histological markers of infection in animals receiving Moringa essential oil and L. reuteri (MT180537) alone or in combination. However, significant synergism between Moringa essential oil and L. reuteri (MT180537) could not be observed. Our data confirms the importance of in vivo experiments in deducing pharmacological interactions.

Resumo Vaginite aeróbica (VA) é uma infecção vaginal recorrente definida recentemente, que é tratada com antibióticos. No entanto, o uso excessivo e prolongado de antibióticos perturba a microflora vaginal saudável e leva ao surgimento de resistência aos antibióticos entre os patógenos. Esta situação levou os pesquisadores a explorar antimicrobianos alternativos. O presente estudo descreve a eficácia antimicrobiana in vitro e in vivo e as interações farmacêuticas entre óleos essenciais vegetais (OE) e cinco bactérias lácticas (BAL), isoladas de vagina sã, contra E. faecalis, um dos principais agentes etiológicos da AV. Os experimentos in vitro confirmam a boa atividade antimicrobiana de ambos os EOs de plantas e sobrenadante livre de células (CFS) de LABs. Com base na alta eficácia antimicrobiana, o óleo essencial de Moringa (MO) foi selecionado para determinar sua natureza de interação com o sobrenadante livre de células (CFS) de cinco cepas de LAB. Sinergismo foi registrado entre MO e CFS de L. reuteri (MT180537). Para validar os resultados in vitro, as respostas profiláticas da aplicação individual e sinérgica de MO e L. reuteri (MT180537) foram avaliadas em um modelo murino AV induzido por E. faecalis (MW051601). A eficácia profilática foi evidenciada por uma redução na intensidade dos sintomas clínicos, contagem de E. faecalis (MW051601) por tecido vaginal, juntamente com uma redução nas alterações associadas a AV nos marcadores histológicos de infecção em animais que receberam óleo essencial de Moringa e L. reuteri (MT180537) sozinho ou em combinação. No entanto, não foi possível observar sinergismo significativo entre o óleo essencial de Moringa e L. reuteri (MT180537). Nossos dados confirmam a importância dos experimentos in vivo na dedução de interações farmacológicas.

Cardiovascular Fitness in Normal Weight and Obese Children and Adolescents - A Systematic Review of Studies Published After 2000s / Condición Cardiovascular en Niños y Adolescentes con Peso Normal y Obesos: Una Revisión Sistemática de Estudios Publicados Después de la Década del 2000

SUMMARY: The primary aim was to gather available data published after the 2000s, on cardiovascular fitness in normal weight and obese children and adolescents. Based on the data, the secondary aims were to identify the most used outcomes and to determine the differences in cardiovascular fitness in the mentioned populations. Following PRISMA recommendations, multiple databases were searched: Google Scholar, PubMed, Cochrane Library, ProQuest, and Research Gate, with additional inclusion criteria: original study published in English, normal weight and obese children and adolescents as participant sample, studies that have assessed cardiovascular fitness parameters, and studies with participant's nutrition state. A total of 19 studies, with a total of 4,988 included participants (both obese and normal weight) were identified, with the most common participants have presented better results in terms of BMI, BF%, VO2max, VO2peak and METs, while the HR values are inconsistently presented. Despite deficiencies the study deficiency in the last two decades, there are differences in the mentioned populations. Further studies should focus on including the technology that reaches teens and families for overweight and obesity prevention and advancements in standard measurements for juvenile overweight and obesity, as well as for the creation, adaption, and validation of measuring instruments. As good framework for future directions, there is a need for more concise and unified measurements of cardiovascular fitness parameters in normally weight and obese children and adolescents.

El objetivo principal fue recopilar datos disponibles publicados después de la década del 2000 sobre la condición cardiovascular en niños y adolescentes con peso normal y obesos. En base a estos datos, los objetivos secundarios fueron identificar los resultados más utilizados y determinar las diferencias en la condición cardiovascular en las poblaciones mencionadas. Siguiendo las recomendaciones de PRISMA, se realizaron búsquedas en múltiples bases de datos: Google Scholar, PubMed, Cochrane Library, ProQuest y Research Gate, con criterios de inclusión adicionales: estudio original publicado en inglés, niños y adolescentes con peso normal y obesidad como muestra participante, estudios que hayan evaluado enfermedades cardiovasculares, parámetros de condición física y estudios con el estado nutricional de los participantes. Se identificaron un total de 19 estudios, con un total de 4.988 participantes incluidos (tanto obesos como con peso normal), siendo las variables más comunes: IMC, %BF, VO2máx, VO2pico, FC, PAD, PAS y MET. Generalmente, los participantes con peso normal han presentado mejores resultados en términos de IMC, %BF, VO2máx, VO2peak y MET, mientras que los valores de FC se presentan de manera inconsistente. Independientemente de la deficiencia de estudios en las últimas dos décadas, existen diferencias en las poblaciones mencionadas. Estudios futuros deberían centrarse en incluir tecnología que llegue a adolescentes y familias para la prevención del sobrepeso y la obesidad y avances en las mediciones estándar del sobrepeso y la obesidad juvenil, así como para la creación, adaptación y validación de instrumentos de medición. Como buen marco para direcciones futuras, se necesitan mediciones más concisas y unificadas de los parámetros de la condición cardiovascular en niños y adolescentes con peso normal y obesos.

Efecto del ejercicio aeróbico sobre la capacidad cardiorrespiratoria en pacientes sobrevivientes de covid-19: meta-análisis / Effect of aerobic exercise on the cardiorespiratory capacity in survivors of covid-19: a meta-analysis

El propósito del estudio fue cuantificar el tamaño de efecto (TE) del ejercicio aeróbico sobre la capacidad cardiorrespiratoria en sobrevivientes de la enfermedad COVID-19, producida por el virus SARS-CoV 2. Se revisaron dos bases de datos (EBSCO host y PubMed) entre los meses de agosto a noviembre del año 2021. Se encontraron 142 656 posibles artículos y, luego de varios filtros, se incluyeron 9 estudios que cumplían los requisitos de inclusión. Se usó el modelo de efectos aleatorios. Se obtuvieron 12 TE en un primer meta-análisis que tuvo sesgo (según prueba de Egger). Tras identificar y eliminar grupos con TE extremo, se obtuvo un modelo corregido y sin sesgo con 7 estudios y 9 TE, donde se encontró que el ejercicio aeróbico tiene un efecto significativo, positivo y de magnitud grande sobre la condición cardiorrespiratoria en sobrevivientes a la enfermedad de COVID-19 (TE = 0.849; IC95%: 0.715 - 0.982; . = 7.13; . = 0.522; I. = 0.87%; Egger . = 0.205). Las intervenciones con ejercicio aeróbico favorecen la mejora de la capacidad cardiorrespiratoria en pacientes sobrevivientes de COVID-19. Dos estudios aplicaron solo ejercicio aeróbico, mientras que los otros siete combinaban aeróbico con ejercicio de fuerza y otras modalidades. En todos los casos se tuvo TE significativo. Finalmente, estos resultados fueron relativamente homogéneos, sin evidenciar la influencia de posibles variables moderadoras.

The purpose of this study was to quantify the effect size (TE) of aerobic exercise on cardiorespiratory capacity in survivors of the COVID-19 disease caused by the SARS-CoV 2 virus. Two data bases (EBNSCO host and PubMed) were reviewed over the months of August through November, 2021. A total 142 656 potential articles were reviewed and, after applying several filters, 9 studies that met the requirements for inclusion were included. The random effect model was used. A first meta-analysis that was biased (according to Egger test) obtained 12 TE. After identifying and eliminating groups with an extreme TE, a corrected, unbiased model was obtained with 7 studies and 9 TE was obtained, where it was found that aerobic exercise has a significant, positive and large-magnitude effect on the cardiorespiratory condition on survivors of the COVID-19 disease (TE = 0.849; IC95%: 0.715 - 0.9 82; Q = 7.13; p = 0.522; I2 = 0.87%; Egger p = 0.205). Interventions with aerobic exercise foster an improvement in cardiorespiratory capacity in patients who survived COVID-19. Two studies applied aerobic exercise only, whereas the other seven combined aerobic exercise with strength exercise and other modes. In all cases, a significant TE was obtained. Finally, these results were relatively homogeneous, with no evidence for the influence of possible moderating variables.

O objetivo do estudo foi quantificar o tamanho do efeito (TDE) do exercício aeróbico na aptidão cardiorrespiratória em sobreviventes da doença COVID-19, produzida pelo vírus SARS-CoV 2. Foram revisadas duas bases de dados (EBSCO host e PubMed) entre agosto e novembro de 2021. Foi encontrado um total de 142.656 artigos em potencial e, após vários filtros, foram incluídos 9 estudos que atendiam aos requisitos de inclusão. Foi usado o modelo de efeitos aleatórios. Foram obtidos 12 TDE em uma primeira metanálise que era tendenciosa (de acordo com o teste de Egger). Depois de identificar e eliminar os grupos com TDE extremo, foi obtido um modelo corrigido e imparcial com 7 estudos e 9 TDE, no qual se constatou que o exercício aeróbico tem um efeito significativo, positivo e de grande magnitude sobre a aptidão cardiorrespiratória em sobreviventes da doença COVID-19 (TDE = 0,849; IC95%: 0,715 - 0,982; . = 7,13; . = 0,522; I. = 0,87%; Egger . = 0,205). As intervenções com exercícios aeróbicos melhoram o condicionamento cardiorrespiratório em sobreviventes da COVID-19. Dois estudos usaram apenas exercícios aeróbicos, enquanto os outros sete combinaram exercícios aeróbicos com exercícios de força e outras modalidades. Em todos os casos, houve um TDE significativo. Por fim, esses resultados foram relativamente homogêneos, sem evidências da influência de possíveis variáveis moderadoras.

MICROBIAL PROFILE AND ANTIBIOTIC SUSCEPTIBILITY OF BACTERIAL PATHOGENS ISOLATED FROM PAPER CURRENCIES CIRCULATING IN SOME RESTAURANTS AND BUTCHERIES IN HAWASSA, SIDAMA, ETHIOPIA, 2020-21

Currency notes could play a signicant role in transmitting pathogenic microorganisms amongst individuals in the society. This study was aimed to determine the microbial prole and Antibiotic susceptibility of bacterial pathogens isolated from Ethiopian paper notes in circulation. 64 currency paper notes of different denomination were tested for bacterial contamination using standard microbiological methods. Antibiotic susceptibility proles of the isolates were determined with approved methods. Results were analyzed using descriptive statistics. Overall mean AMBC was 4.08 log units, with the highest 6.58 log units recorded from denomination 5 followed by 4.50, 3.03, 2.20 log units from denominations 10, 50 and 100 respectively. Total Coliforms (TC) displayed the same pattern with the highest mean counts of 6.52 log units, from denomination 5 and lowest counts of 2.19 log units from denomination 100. Out of 64 currency notes, 35 (54.7%) were contaminated with bacteria. The predominant bacteria isolates were E. coli (60.5%), Salmonella spp. (23.6%) and Shigella spp. (13.2%). Each isolate was resistant to four or more antibiotics tested. All isolates were resistant against Cefepime and Tetracycline and sensitive to Ceftriaxone. This study revealed that currency notes are contaminated with pathogenic bacteria and in most cases these bacterial isolates were resistant to commonly prescribed antibiotics. Therefore, contaminated notes are identied as potential public health threat, because pathogens can be spread by circulating the notes and become source of infection. Awareness creation is important among public in this regard.

A comparative study of effects of pranayama and aerobic exercise on spirometric indices in the age group of 30–50 years

Background: Increasing awareness to lifestyle disease has led to more participation of people in taking up various forms of exercise to avail more health benefits. The ability to perform physical exercise is related to cardiovascular systems capacity to supply oxygen to muscles and pulmonary systems ability to clear carbon di oxide from blood via lungs. Spirometry is a physiological test that measures the volume and flow of air that can be inhaled and exhaled. Aim and Objectives: The purpose of this study is not only to assess the beneficial effects of pranayama and aerobic exercises but to compare the improvements in the lung functions among these two modalities of exercises. Materials and Methods: It is a non-randomized cross-sectional comparative study. Total 150 participants of both sexes aged 30–50 years were selected and divided equally into three groups: Pranayama group, aerobic exercise group, and control group who were doing pranayama and aerobic exercise and no exercise respectively from the past 3 months were included in the study. The participants were assessed by their anthropometric parameters, pulse rate, respiratory rate, blood pressure, forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC, and peak expiratory flow rate (PEFR). Results: Among Pranayama groups, there was significantly higher level of FVC, FEV1, FEV1/FVC ratio, and PEFR as compared to aerobic exercise group and control group. Conclusion: Both pranayama and aerobic exercise play an important role in improving the pulmonary functions but effects were more pronounced with pranayama.

Aerobic activity reducing depression in school-age children: a multiple mediation effects analysis based on five dimensions of psychosocial functioning / 中国康复理论与实践

ObjectiveTo explore the mechanism of aerobic capacity on depression in school-age children, and the multiple mediators of the five dimensions of psychosocial functioning (emotional symptoms, conduct problems, peer problems, prosocial behavior and hyperactivity) between aerobic capacity and depression. MethodsFrom October to December, 2021, pupils of Grade two to Grade five from two primary schools were chester-sampled and investigated using 20-meter multistage shuttle run test, Depression Self-Rating Scale for Children, Self-reported Strengths and Difficulties Questionnaire. ResultsA total of 391 pupils underwent 20-meter multistage shuttle run test, and 312 out of them answering the questionnaires, and 294 questionnaires were valid. Aerobic capacity, depression, emotional symptoms, peer problems, prosocial behavior and hyperactivity were significantly correlated with each other (|r| > 0.127, P < 0.05) (except aerobic capacity and peer problems, and emotional symptoms and prosocial behavior). The results of the multiple mediation effect model showed that aerobic capacity could directly and negatively predict depression, and the mediating effects of emotional symptoms, peer problems, prosocial behavior and hyperactivity were significant, accounting for 34.37%, 12.54%, 34.06% and 17.80% of the total mediating effect, respectively. ConclusionThe aerobic capacity could not only directly affect depression of school-age children, but also improve their psychosocial functioning by reducing emotional symptoms, peer problems and hyperactivity, and increasing prosocial behavior, to indirectly affect their depression.

The effects of aerobic exercise on renal fibrosis and apoptosis in spontaneously hypertensive rats / 中华物理医学与康复杂志

Objective:To explore any effect of regular aerobic exercise on renal fibrosis and apoptosis in rats with spontaneous hypertension.Methods:Thirty 6-week-old male spontaneously hypertensive rats were randomly divided into a sedentary group (group HS) and an exercise group (group HE). Ten age- and sex-matched Wistar-Kyoto rats formed a control group. The rats in group HE underwent 12 weeks of swimming exercise lasting 60 minutes, five times a week, while the other two groups were kept quiet in their cages. Before and after the training, the tail artery blood pressure of each rat was measured. Renal function was evaluated after the experiment by measuring 24h urine protein, blood urea nitrogen and serum creatinine levels, while the degree of renal interstitial fibrosis was measured using Masson staining and the collagen volume fraction was calculated. The number of apoptotic cells in the renal tubular epithelial tissue was recorded by TUNEL staining and the apoptosis rate was calculated. The expression of renal transforming growth factor β1 (TGF-β1), Smad2/3, Smad7, Bax and Bcl-2 protein were detected using western blotting.Results:After the intervention, the average systolic and diastolic blood pressure and mean arterial pressure of group HS had increased significantly, while those of group HE had decreased significantly, with no significant changes in those measurements among the control group. Compared with the control group, after the intervention, the average blood pressure, 24h urinary protein, blood urea nitrogen and serum creatinine, as well as the cell apoptosis rate and expression of TGF-β1, Smad2/3 and Bax had increased significantly, and that of Smad7 and Bcl-2 had decreased significantly in group HS. And compared with group HS, in group HE the average blood pressure, 24h urinary protein, blood urea nitrogen, serum creatinine and the cell apoptosis rate had decreased significantly, together with the expression of TGF-β1, Smad2/3 and Bax, but the average expression of Smad7 and Bcl-2 had increased significantly.Conclusion:Regular aerobic exercise can relieve the renal dysfunction seen in spontaneous hypertension, at least in rats, by inhibiting renal fibrosis and apoptosis.

Effects of stem cells therapy combined with aerobic exercise on ventricular remodeling in rats with acute myocardial infarction / 中华物理医学与康复杂志

Objective:To explore the effect of supplementing stem cell therapy with aerobic exercise in left ventricle remodeling after myocardial infarction.Methods:Sixty 6-week-old male Wistar rats had acute myocardial infarction induced by ligation of the anterior descending coronary artery. They were then randomly divided into a model group, a stem cell group, an exercise group and an observation group. Another ten healthy Wistar rats formed a sham operation group. The rats in the stem cell and observation groups were infused with a suspension of bone marrow mesenchymal stem cells through the tail vein. Beginning four weeks later, the exercise and observation groups underwent 60 minutes of aerobic treadmill exercise 5 days per week for 8 weeks. At the beginning and end of the eight weeks the rats′ exercise performance was evaluated using a graded treadmill exercise test. And after the last training session cardiac structure and function were detected using ultrasound imaging. Tissue was then collected from the left ventricles and the collagen volume fractions were calculated. The expression of myocardial brain natriuretic peptide (BNP), heavy chain β-myosin (β-MHC) and α-MHC mRNA was detected using real-time fluorescence quantitative PCRs.Results:Compared with the sham operation group, the time and distance to exhaustion shortened significantly in the model group, with a significant decrease in the average maximum running speed, left ventricle ejection fraction (LVEF), left ventricle shortening fraction (LVFS), expression of α-MHC and the α-MHC/β-MHC ratio. There was a significant increase in the average resting heart rate, collagen volume fraction, expression of BNP and β-MHC in the model group. Compared with the model group, there was a significant increase in the average LVEF and LVFS of the stem cell group as well as in the time and distance to exhaustion, maximum running speed, expression of α-MHC and in the α-MHC/β-MHC ratio of the observation group, but a significant decrease in the average collagen volume fraction of the stem cell group compared with the observation group, together with the resting heart rate, collagen volume fraction, the expression of BNP and of β-MHC. Compared with the stem cell group, the observation group showed a significant increase in the average time and distance to exhaustion, maximum running speed, expression of α-MHC and the α-MHC/β-MHC ratio, with a significant decrease in the average resting heart rate, collagen volume fraction, expression of BNP and β-MHC.Conclusion:Aerobic exercise or stem cell therapy alone can inhibit left ventricular remodeling and improve cardiac function after myocardial infarction, at least in rats. The combination of the two treatments has a synergistic effect and can further enhance the effect of stem cell therapy.

Efficacy of nutritional intervention and exercise rehabilitation therapy on sarcopenia in elderly patients with type 2 diabetes mellitus / 中华健康管理学杂志

Objective:To observe the effect of nutrition intervention and exercise rehabilitation treatment on the sarcopenia in elderly patients with type 2 diabetes.Methods:It was a cross-sectional study. From March 2019 to September 2020, 101 elderly patients with type 2 diabetes complicated with sarcopenia treated in the Department of Endocrinology of Tianjin Third Central Hospital were enrolled in this study. The patients were divided into four groups with propensity score matching method: sarcopenia education group without nutrition and resistance training group (group A, n=22), simple nutrition intervention group (group B, n=28), nutritional intervention combined with resistance training group (group C, n=27) and nutritional intervention combined with aerobic and resistance training group (group D, n=24). All the patients were intervened for 24 weeks, two patients in groups C and D dropped due to their own reasons. The 25-dihydroxy vitamin D3 (25(OH)D 3), grip strength, muscle mass of the limbs and short physical performance battery (SPPB) scores were measured before and 24 weeks after the intervention in all the participants. Results:After the intervention, the 25(OH)D 3 levels in the B, C, D groups was (33.45±4.05), (33.68±4.69), (34.28±5.58) μg/L, respectively, all were higher than those before the treatment (all P<0.01), and there was no significant differences among the three groups ( P>0.05). The muscle mass in the B, C, D groups after intervention was 5.650 (5.102, 6.658), 6.601 (6.007, 7.156) and 6.520 (6.017, 7.302) kg/m 2, respectively, all were significantly higher than those before the treatment (all P<0.01); the muscle mass in group C and D increased more significantly than that in group B ( P<0.01), but there was no significant differences between group C and D ( P>0.05). After the intervention, the muscle strength in the C and D groups was 20.60 (19.20, 24.55) kg and 21.15 (19.43, 26.63) kg, and the SPPB scores was 8.00 (7.00, 9.00) points and 8.00 (8.00, 9.00) points, respectively, all were higher than those before the intervention (all P<0.01), but there was no significant differences between the two groups(both P>0.05). The SPPB function score in group D was better than that in group C, the difference was statistically significant ( P<0.05). Conclusions:Nutritional intervention can improve the muscle mass in elderly type 2 diabetes patients with sarcopenia. Combined with rehabilitation training, the muscle strength and muscle function of these patients could also be improved, and the improvement of muscle mass is better than that in patients receiving nutritional intervention only. In terms of increasing muscle strength, the two kinds of rehabilitation training are equivalent. If combined with aerobic exercise, it can also improve the muscle function of these patients.

Effect of exercise on prehypertension and hypertension in middle-aged and elderly people in Asian populations: a meta-analysis / 中华行为医学与脑科学杂志

Objective:To systematically evaluate the effect of exercise on blood pressure of middle-aged and elderly Asian populations with prehypertension and hypertension, and to provide theoretical basis for formulating accurate exercise prescriptions.Methods:Randomized controlled trials on the effect of exercise on blood pressure in middle-aged and elderly patients with prehypertension and hypertension were collected by PubMed, EMBASE, the Cochrane Library, Web of Science, CNKI and Wanfang Database.The quality of the included studies was evaluated by the Cochrane risk bias assessment tool, and the meta-analysis was performed with Stata 15.0 software.Results:A total of 23 articles and 2 095 subjects were included.Meta analysis showed that compared with the control group, aerobic exercise(WMD=-9.94, 95% CI=-12.59--7.29, P<0.001), resistance exercise(WMD=-11.15, 95% CI=-18.36--3.95, P=0.002) and aerobic combined resistance exercise(WMD=-6.09, 95% CI=-8.87--3.31, P=0.005) could reduce the systolic blood pressure level.Aerobic exercise(WMD=-6.46, 95% CI=-8.20--4.72, P<0.001) and resistance exercise(WMD=-4.38, 95% CI=-8.07--0.69, P=0.02) could reduce the level of diastolic blood pressure, while aerobic combined resistance exercise(WMD=-4.88, 95% CI=-12.87-3.11, P=0.232)had no significant effect on diastolic blood pressure.The results of subgroup analysis indicated that the differences of age, baseline blood pressure, exercise intensity, exercise time, exercise frequency, and motion cycle were the main sources of heterogeneity.The funnel plot and Egger's test indicated that there was no publication bias in this Meta-analysis. Conclusion:Aerobic exercise and resistance exercise both have positive effects on reducing blood pressure of middle-aged and elderly Asian populations with prehypertension and hypertension.

Health and functioning benefits of aerobic exercise rehabilitation for substance abuse-induced mental and behavioral disorders: a systematic review / 中国康复理论与实践

ObjectiveTo examine the interventions and health benefits of aerobic exercise for substance abusers using International Classification of Diseases, Eleventh Revision (ICD-11) and International Classification of Functioning, Disability and Health (ICF) framework. MethodsThe PICO framework was developed and randomized controlled trials were searched in PubMed, Web of Science, Embase, and CNKI dated from the inception of the databases to April, 2023. Then a systematic review was conducted. ResultsSeven randomized controlled trials involving 498 participants from three countries were included. The studies were mainly published in international journals such as International Journal of Mental Health and Addiction, Psychiatry Research, Mental Health and Physical Activity, BMC Sports Science, and Medicine and Rehabilitation, and covered the period from 2010 to 2022. The substance abusers in the included studies were classified into seven categories of mental and behavioral disorders, including methamphetamine dependence, cocaine dependence, cannabis dependence, opioid dependence, sedative dependence, heroin dependence, and ketamine dependence. Aerobic exercise activities included running, cycling, Tai Chi, Qigong, yoga, jumping rope, climbing, etc., with a frequency of 20 to 60 minutes per session, one to ten times per week. The activity intensity was mainly concentrated in moderate to high intensity, and the duration ranged from 12 to 48 weeks. The health outcomes were evaluated in six aspects: physical motor function, cognitive function, emotional functioning, medication cravings, physical fitness, and overall function and quality of life. ConclusionBased on ICD-11 and ICF, a theoretical framework was constructed to evaluate the health effects of aerobic exercise for substance abusers. Aerobic exercise could improve flexibility and balance, grip strength, vertical jump height, and sit and reach distance, as well as enhance physical fitness, strength, flexibility, speed and agility in substance abusers' physical function. In terms of cognitive function, aerobic exercise could help to improve working memory, attention and executive function, as well as cognitive and neurological functions. Aerobic exercise rehabilitation could also improve psychological health, such as anxiety, depression and fatigue, and increase the ability to resist substance dependence in substance abusers. In addition, aerobic exercise rehabilitation could improve physical fitness, such as body mass, blood pressure and blood lipid levels, and reduce the risk of cardiovascular disease, diabetes and other diseases. It could also improve overall social function, increase social adaptability and quality of life, and reduce the risk of substance abuse relapse in substance abusers.

Jianpi Yangzheng Xiaozheng Decoction Affect Proliferation and Stemness of Gastric Cancer HGC-27 Cells by Inhibiting Aerobic Glycolysis / 中国实验方剂学杂志

ObjectiveTo observe the effect of Jianpi Yangzheng Xiaozheng decoction （JYXD） on the proliferation and stemness of the human gastric cancer （GC） cell line HGC-27 by inhibiting aerobic glycolysis， and explore the underlying mechanism. MethodMethyl thiazolyl tetrazolium （MTT） assay was employed to determine the survival rate and chemotherapy sensitivity of HGC-27 cells treated with JYXD （0.25， 0.5， 1， 2， 4， 8， 16， 32 g·L-1）. Colony formation assay was employed to detect the effect of JYXD （2， 4， 8 g·L-1） on the colony formation of the cells. The aerobic glycolysis level of HGC-27 cells after treatment with JYXD was measured by glucose assay kit and lactic acid assay kit. The proportion of stem cell subsets in HGC-27 cells was detected by flow cytometry. Western blot was employed to determine the expression of glycolysis-associated proteins such as lactate dehydrogenase （LDH）， hexokinase 2 （HK2）， glucose transporter 1 （GLUT1）， and pyruvate kinase isozyme M2 （PKM2）， and the expression of stemness-associated proteins such as octamer-binding transcription factor 4 （OCT4）， SRY-box transcription factor 2 （SOX2）， and Nanog. ResultJYXD （0.5， 1， 2， 4， 8， 16， 32 g·L-1） inhibited the activity of HGC-27 cells （P<0.05， P<0.01）， with the inhibitory concentration 50（IC50） of 4.83 g·L-1， and it improved the sensitivity of HGC-27 cells to cisplatin chemotherapy. Compared with the control group， JYXD （2， 4， 8 g·L-1） reduced the colony formation number of HGC-27 cells （P<0.01） in a concentration-dependent manner. Flow cytometry showed that compared with that in the control group， the proportion of CD44+CD24+ALDH+ population in the cells treated with JYXD （2， 4， 8 g·L-1） decreased （P<0.05）. In addition， JYXD （2， 4， 8 g·L-1） inhibited the glucose uptake and lactic acid production of HGC-27 cells. Western blot showed that compared with the control group， JYXD （2， 4， 8 g·L-1） down-regulated the expression levels of SOX2， Nanog， OCT4， PKM2， LDH， GLUT1， and HK2 （P<0.05， P<0.01） in a concentration-dependent manner. ConclusionJYXD may inhibit the proliferation and reduce the stemness of HGC-27 cells by regulating the aerobic glycolysis.

ConclusionThe moderate intensity aerobic combined with low resistance exercise developed based on WHO-FICs can improve the cardiac function, lung function, cardiac load and motor function of old patients with coronary heart disease and hypertension.

Effects of aerobic exercise on cognitive function in male patients with chronic schizophrenia / 四川精神卫生

BackgroundThe schizophrenia is majorly treated with drug and through physical therapy. However， both treatments would lead to adverse reactions， which could affect therapy adherence and treatment efficacy. Previous studies have shown that aerobic exercise can help alleviate cognitive function in patients with Alzheimer's disease and depressive disorder. At present， little research has been done on such alleviation in schizophrenia patients. ObjectiveTo explore the effect of aerobic exercise on cognitive function in male patients with chronic schizophrenia， so as to provide references for relevant treatments. MethodsA total of 76 male patients with chronic schizophrenia hospitalized in the Fourth People's Hospital of Wuhu between December 2022 and April 2023 were selected as the study subjects and， in accordance with random number table， divided into study group （n=36） and control group （n=40）. Both groups received conventional drug treatment. On this basis， the study group received a 60-minute aerobic exercise 5 times a week for 8 weeks as intervention. Before and after intervention， assessment of cognitive function was performed by using MATRICS Consensus Cognitive Battery （MCCB） and Stroop Color Word Test （SCWT）. ResultAfter intervention， compared with the control group， the study group spent less time on finishing the Trail Making Test and scored higher in both the spatial span test and maze test （Z=-2.070， -2.306， -2.375， P<0.05）. Repeated measure ANOVA results showed that the time main effect of Hopkins Verbal Learning Test score was statistically significant in the two groups after intervention （F=39.067， P<0.05）. So was the interaction effect between the time and group of the Brief Visuospatial Memory Test and Verbal Fluency Test scores （F=10.092， 9.252， P<0.05）. After intervention， the scores of the Brief Visuospatial Memory Test and Verbal Fluency Test in the study group were higher than those in the control group （t=6.689， 4.249， P<0.05）. As for the study group itself， the scores were higher than those before intervention （t=23.746， 23.842， P<0.05）. After intervention， the numbers of correct reading in color test and word test in the study group were more than those in the control group （Z=-2.358， -2.771， P<0.05）. The interaction effect between the time and group of the reaction time in color test， word test and color word interference test were statistically significant in both groups （F=23.383， 19.888， 19.662， P<0.05）. After intervention， the reaction time in color test and color word interference test of the study group was shorter than those of the control group （t=4.895， 6.163， P<0.05）. As for the study group itself， the reaction time were shorter than before intervention （t=54.318， 42.425， 42.141， P<0.01）. ConclusionAerobic exercise may help alleviate the cognitive problems in male patients with chronic schizophrenia in terms of information processing speed， working memory， reasoning/problem solving ability， word learning and memorizing， visual learning and memorizing， and executive function. ［Funded by Wuhu Science and Technology Plan Project （number， 2021jc2-3）］

The structure and function analysis of bacterial community during aerobic composting of chicken manure / 生物工程学报

In order to determine the changes of bacterial community structure and function in the early, middle and late stage of aerobic composting of chicken manure, high-throughput sequencing and bioinformatics methods were used to determine and analyze the 16S rRNA sequence of samples at different stages of composting. Wayne analysis showed that most of the bacterial OTUs in the three composting stages were the same, and only about 10% of the operational taxonomic units (OTUs) showed stage specificity. The diversity indexes including Ace, Chao1 and Simpson showed a trend of increasing at first, followed by decreasing. However, there was no significant difference among different composting stages (P < 0.05). The dominant bacteria groups in three composting stages were analyzed at the phylum and genus levels. The dominant bacteria phyla at three composting stages were the same, but the abundances were different. LEfSe (line discriminant analysis (LDA) effect size) method was used to analyze the bacterial biological markers with statistical differences among three stages of composting. From the phylum to genus level, there were 49 markers with significant differences among different groups. The markers included 12 species, 13 genera, 12 families, 8 orders, 1 boundary, and 1 phylum. The most biomarkers were detected at early stage while the least biomarkers were detected at late stage. The microbial diversity was analyzed at the functional pathway level. The function diversity was the highest in the early stage of composting. Following the composting, the microbial function was enriched relatively while the diversity decreased. This study provides theoretical support and technical guidance for the regulation of livestock manure aerobic composting process.

High expression of death-associated protein 5 promotes glucose metabolism in gastric cancer cells and correlates with poor survival outcomes / 南方医科大学学报

OBJECTIVE@#To investigate the prognostic value of death-associated protein 5 (DAP5) in gastric cancer (GC) and its regulatory effect on aerobic glycolysis in GC cells.@*METHODS@#We analyzed DAP5 expression levels in GC and adjacent tissues and its association with survival outcomes of GC patients using public databases. We collected paired samples of GC and adjacent tissues from 102 patients undergoing radical resection of GC in our hospital from June, 2012 to July, 2017, and analyzed the correlation of DAP5 expression level detected immunohistochemically with the clinicopathological parameters of the patients. Cox regression analysis, Kaplan-Meier analysis, and ROC curves were used to explore the independent risk factors and the predictive value of DAP5 expression for 5-year survival of the patients. In the cell experiments, we observed the changes in aerobic glycolysis in MGC-803 cells following lentivirus-mediated DAP5 knockdown or overexpression by measuring glucose uptake and cellular lactate level and using qRT-PCR and Western blotting.@*RESULTS@#Analysis using the public databases showed that DAP5 was highly expressed in GC and correlated with tumor progression and poor survival outcomes of the patients (P < 0.05). In the clinical samples, DAP5 expression was significantly higher in GC than in the adjacent tissues (3.19±0.60 vs 1.00±0.12; t=36.863, P < 0.01), and a high expression of DAP5 was associated with a reduced 5-year survival rate of the patients (17.6% vs 72.5%; χ2=29.921, P < 0.05). A high DAP5 expression, T3-4, N2-3, and CEA≥5 ng/mL were identified as independent risk factors affecting 5-year survival outcomes of GC (P < 0.05), for which DAP5 expression showed a prediction sensitivity, specificity and accuracy of 73.2%, 80.4% and 79.0%, respectively. In MGC-803 cells, DAP5 knockdown significantly reduced glucose uptake, lactate level and the expressions of GLUT1, HK2 and LDHA, and DAP5 overexpression produced the opposite effects (P < 0.05).@*CONCLUSION@#A high expression of DAP5 in GC, which enhances cellular aerobic glycolysis to promote cancer progression, is correlated with a poor survival outcome and may serve as a biomarker for evaluating long-term prognosis of GC patients.

Effect of Lactate on Immune Cells in Tumor Microenvironment and Progress of Related Target Therapy / 肿瘤防治研究

The relationship between tumor metabolism and immunity is complex and diverse. To date, the role of tumor-specific metabolic reprogramming in shaping the specific tumor microenvironment in tumor immunotherapy remains unclear. Lactic acid is the main product of glycolysis, and the aerobic glycolysis of tumor cells causes lactic acid to accumulate in the microenvironment. Recent studies have shown that the accumulation of lactic acid in the tumor microenvironment hinders anti-tumor immunity, especially affects the function, differentiation, and metabolism of immune cells, and participates in tumor immune escape, thus promoting tumor. This article reviews the effects of lactate accumulation in the tumor microenvironment on dendritic cells, T cells, NK cells, tumor-associated macrophages, and myeloid-derived suppressor cells. Targeted intervention of lactate production and efflux by tumor cells is expected to become a new strategy for tumor immunotherapy.
