The plasma level changes of VEGF and soluble VEGF receptor-1 are associated with high-altitude pulmonary edema

Hypoxia-induced plasma levels of VEGF and sFlt-1 are responsible for increased vascular permeability occurred in both brain and pulmonary edema. Currently, it remains unclear the exact roles of VEGF and sFlt-1 in High Altitude Pulmonary Edema (HAPE) pathogenesis. In this study, plasma levels of VEGF and sFlt-1 from 10 HAPE and 10 non-HAPE subjects were measured and compared. The results showed that plasma levels of both VEGF and sFlt-1 in HAPE patients were significantly increased as compared to the non-HAPE group. Interestingly, increased plasma levels of these two protein factors were markedly reduced after treatments. As compared to VEGF, sFlt-1 was much more affected by hypoxia and treatments, suggesting this factor was a key factor contributed to HAPE pathogenesis. Importantly, the ratio of sFlt-1 and VEGF in group of either non-HAPE or HAPE after recovery was significantly lower than the ratio in HAPE patients prior to treatments. Our findings suggested that sFlt-1 was a key factor that involved in HAPE pathogenesis and the sFlt-1/VEGF ratio could be used as a sensitive diagnostic marker for HAPE

Intermediate role of gut microbiota in vitamin B nutrition and its influences on human health

Vitamin B consists of a group of water-soluble micronutrients that are mainly derived from the daily diet. They serve as cofactors, mediating multiple metabolic pathways in humans. As an integrated part of human health, gut microbiota could produce, consume, and even compete for vitamin B with the host. The interplay between gut microbiota and the host might be a crucial factor affecting the absorbing processes of vitamin B. On the other hand, vitamin B supplementation or deficiency might impact the growth of specific bacteria, resulting in changes in the composition and function of gut microbiota. Together, the interplay between vitamin B and gut microbiota might systemically contribute to human health. In this review, we summarized the interactions between vitamin B and gut microbiota and tried to reveal the underlying mechanism so that we can have a better understanding of its role in human health

Wet cupping for hypertension: a systematic review and meta-analysis

To assess the efficacy and safety of wet cupping in adults with hypertension, we conducted a systematic review and meta-analysis using 13 databases. Wet cupping alone or in combination with antihypertensive medication or acupuncture was used. Seven randomized trials were included, most not of high methodological quality. A few small studies suggested that wet cupping alone versus antihypertensive medication significantly reduced blood pressure and Traditional Chinese Medicine syndrome (hypertension-related symptoms). However based on current evidence, no firm conclusions can be drawn and no clinical recommendations made. Research projects included need validation. Studies indicate that wet cupping is a safe therapy

Resilience mediates the association between alexithymia and stress in Chinese medical students during the COVID-19 pandemic

Background Evidence indicates that medical students have had high rates of mental health problems, especially during the COVID-19 pandemic, which could be affected by alexithymia—a marked dysfunction in emotional awareness, social attachment and interpersonal relationships—and stress. However, psychological resilience might relieve alexithymia and stress levels.Aims This study aimed to investigate the role of resilience in alexithymia and stress in medical students.Methods A total of 470 medical students completed online and offline surveys, including the Toronto Alexithymia Scale-20 (TAS-20), the Connor-Davidson Resilience Scale (CD-RISC) and the College Student Stress Questionnaire (CSSQ). The data of five participants were excluded because of a lack of integrity. Mann-Whitney U test or Kruskal-Wallis test was used to compare group differences in the CD-RISC scores among categorical variables. Spearman correlation analysis was employed to evaluate the associations between resilience and alexithymia and between resilience and stress. Mediation analysis was used to test the mediating effect of resilience between alexithymia and stress.Results Of the medical students considered in the analysis, 382 (81.28%) were female and 88 (18.72%) were male. There was a significant negative correlation between the TAS-20 scores and the total and subtotal CD-RISC scores (p<0.001). The CSSQ scores also significantly negatively correlated with the total and subtotal CD-RISC scores (p<0.001). Resilience mediated the relationship between alexithymia and stress (total effect=1.044 7, p<0.001). The indirect effect of alexithymia significantly impacted stress through resilience (effect=0.167 0, 95% CI: 0.069 to 0.281).Conclusions Our findings suggest that resilience might effectively reduce alexithymia and stress. They also contributed to a better understanding of the mediating effects of resilience on alexithymia and stress during the COVID-19 pandemic. The evidence from these results encourages universities to focus on improving students’ resilience

Effects of Intellectual Activities on Different Domains of Cognitive Function in Elderly People

Background Intellectual activities such as reading and playing puzzle games can slow the decline of cognitive function in the elderly, but the effects of specific types of such activities on cognitive function and cognitive domains need to be further studied. Objective To explore the influence of common types of intellectual activities on cognitive function and cognitive domains of the elderly in the community. Methods From May to August 2022, stratified convenience sampling was used to select elderly people from four communities in Nanjing, Changzhou, Nantong and Xuzhou of Jiangsu Province. A face-to-face survey was conducted with a general information questionnaire and the Montreal Cognitive Assessment (MoCA) Beijing edition to collect data regarding sociodemographics, frequency and types of intellectual activities, and cognitive function. Stepwise multiple regression analysis was used to explore the relationship between intellectual activities and different cognitive domains. Results In total, 782 cases attended the survey, and 758 of them (96.93%) who completed it were included for analysis, including123 from Nanjing, 197 from Changzhou, 240 from Nantong, and 198 from Xuzhou. The intellectual activities done by these older people include learning new knowledge (n=170), playing chess and cards (n=228), reading (n=228), singing (n=59), playing puzzle games (n=57), helping grand children with their homework (n=42), painting (n=16), playing a musical instrument (n=47), and practicing calligraphy (n=30). Stepwise multiple linear regression analysis showed that learning new knowledge, reading, helping grand children with their homework, playing puzzle games and playing musical instruments were associated with cognitive function (P<0.05). Learning new knowledge (B=0.250), reading (B=0.590), playing puzzle games (B=0.585), helping grand children with their homework (B=0.711), and playing musical instruments (B=0.643) were the influencing factors of Visuospatial/Executive (P<0.05). Learning new knowledge (B=0.219) was an influencing factor of Abstraction and Delayed recall/Memory (B=0.727) (P<0.05). Reading was a factor affecting Naming (B=0.095), Attention (B=0.207), Language (B=0.290), Abstraction (B=0.241), and Delayed recall/Memory (B=0.377) (P<0.05). Playing puzzle games (B=0.290) and playing musical instruments (B=0.278) were the influencing factors of Language (P<0.05). Among various types of activities, reading was included in a total of seven regression equations, with a standardized regression coefficient of 0.225 for its impact on the total score of MoCA, which was higher than that of the other types. Conclusion Intellectual activities such as reading, learning new knowledge, playing puzzle games, helping grand children with their homework and playing a musical instrument can maintain or improve the cognitive function of the elderly in the community. The effects of different types of intellectual activities on cognitive function are domain-specific, which has a positive significance for the prevention and intervention of cognitive function decline of the elderly

Effectiveness and Safety of Moxibustion on Constipation: A Systematic Review and Meta-Analysis

Aim. This study aimed to evaluate the effects and safety of moxibustion in the management of constipation. Background. Constipation is extremely common in clinical practice and causes physical and mental pain to patients. This study aimed to evaluate the effects and safety of moxibustion in the management of constipation. Methods. Studies on moxibustion for constipation published up to November 2019 were searched in PubMed; EBSCO; EMBASE; Cochrane Library; and three Chinese databases, namely, China National Knowledge Internet, Wanfang, and China Biomedical Network. The methodological quality of the included studies was assessed on the basis of the CLEAR NPT system evaluation methods of Boutron. Further meta-analysis was performed using the RevMan 5.3 and Stata 15.0 software. Results. Ten randomized controlled trials involving 760 patients were included in this study. The meta-analysis revealed that, in comparison to western medicine treatment or other Chinese medicine methods (control group), moxibustion (experimental group) had a higher total effective rate (RR = 1.30, 95% CI [1.21, 1.40], P<0.00001), and the clinical effectiveness of the experimental group was higher than that of the control group in any subgroup analysis. The first defecation time of the experimental group was shorter than that of the control group (SMD = −1.36, 95% CI [−2.03, −0.68], P<0.0001). The clinical symptom score of the patients in the experimental group was lower than that in the control group (SMD = −0.65, 95% CI [−1.00, −0.30], P=0.0003). The patients in the experimental group had higher scores on Bristol stool form scale than those in the control group (MD = 0.99, 95% CI [0.48, 1.50], P=0.0001). However, there was no obvious difference in safety between the two groups (RR = 0.38, 95% CI [0.01, 11.8], P=0.58). Conclusions. Moxibustion may have better effect than other treatments on constipation. However, it is not yet possible to assess the safety level of moxibustion therapy, and the quality of the included literature is low, so rigorous studies are warranted. Implications for Nursing and Health Policy. The focus of this study was to evaluate the effectiveness and safety of moxibustion therapy in constipation. This evaluation showed that moxibustion therapy has a good effect on constipation and provides an effective treatment for constipation patients. Whether moxibustion therapy can be used for different syndrome types deserves further discussion

Deciphering the Enigmatic Influence: Non-Coding RNAs Orchestrating Wnt/β-Catenin Signaling Pathway in Tumor Progression

Dysregulated expression of specific non-coding RNAs (ncRNAs) has been strongly linked to tumorigenesis, cancer progression, and therapeutic resistance. These ncRNAs can act as either oncogenes or tumor suppressors, thereby serving as valuable diagnostic and prognostic markers. Numerous studies have implicated the participation of ncRNAs in the regulation of diverse signaling pathways, including the pivotal Wnt/β-catenin signaling pathway that is widely acknowledged for its pivotal role in embryogenesis, cellular proliferation, and tumor biology control. Recent emerging evidence has shed light on the capacity of ncRNAs to interact with key components of the Wnt/β-catenin signaling pathway, thereby modulating the expression of Wnt target genes in cancer cells. Notably, the activity of this pathway can reciprocally influence the expression levels of ncRNAs. However, comprehensive analysis investigating the specific ncRNAs associated with the Wnt/β-catenin signaling pathway and their intricate interactions in cancer remains elusive. Based on these noteworthy findings, this review aims to unravel the intricate associations between ncRNAs and the Wnt/β-catenin signaling pathway during cancer initiation, progression, and their potential implications for therapeutic interventions. Additionally, we provide a comprehensive overview of the characteristics of ncRNAs and the Wnt/β-catenin signaling pathway, accompanied by a thorough discussion of their functional roles in tumor biology. Targeting ncRNAs and molecules associated with the Wnt/β-catenin signaling pathway may emerge as a promising and effective therapeutic strategy in future cancer treatments

The knowledge, ability, and skills of primary health care providers in SEANERN countries: a multi-national cross-sectional study

Background: Primary health care (PHC) is usually the initial point of contact for individuals seeking to access health care and providers of PHC play a crucial role in the healthcare model. However, few studies have assessed the knowledge, ability, and skills (capacity) of PHC providers in delivering care. This study aimed to identify the capacity of PHC providers in countries of the Southeast and East Asian Nursing Education and Research Network (SEANERN). Methods: A multi-national cross-sectional survey was performed among SEANERN countries. A 1–5 Likert scale was used to measure eight components of knowledge, ability, and skill of PHC providers. Descriptive statistics were employed, and radar charts were used to depict the levels of the three dimensions (knowledge, skill and ability) and eight components. Results: Totally, 606 valid questionnaires from PHC providers were returned from seven countries of SEANERN (China, Myanmar, Indonesia, Thailand, Vietnam, Cambodia, and Malaysia), with a responsive rate of 97.6% (606/621). For the three dimensions the ranges of total mean scores were distributed as follows: knowledge dimension: 2.78~3.11; skill dimension: 2.66~3.16; ability dimension: 2.67~3.06. Furthermore, radar charts revealed that the transition of PHC provider’s knowledge into skill and from skill into ability decreased gradually. Their competencies in four areas, including safe water and sanitation, nutritional promotion, endemic diseases prevention, and essential provision of drugs, were especially low. Conclusions: The general capacity perceived by PHC providers themselves seems relatively low and imbalanced. To address the problem, SEANERN, through the collaboration of the members, can facilitate the appropriate education and training of PHC providers by developing feasible, practical and culturally appropriate training plans
