Qi deficiency is associated with depression in chronic hemodialysis patients

The influence of early diet quality on the mental health of college students: the mediation effects of height and qi-deficiency

Background

In China, the prevalence of mental health issues among college students is a significant concern in society. This study aims to investigate the impact of early dietary quality on the psychological well-being of college students and elucidate the underlying mechanisms through which these effects occur, specifically focusing on height and qi-deficiency as mediators according to Chinese traditional medicine (CTM).

Methods

A total of 655 college students were surveyed in October 2023 using paper-pencil-based questionnaires at four second-tier universities in Sichuan Province. The assessment included mental health, height, and qi-deficiency. Pearson's correlation and linear regression analyses were employed to examine the mediation model and test the hypotheses.

Results

The college students exhibited acceptable levels of early diet quality (M = 3.72) and mental health (M = 3.63), while also presenting mild qi-deficiency symptoms (M = 2.25). Their average height was measured at 164.61 cm. Early diet quality demonstrated significant associations with mental health (r = 0.38, p < 0.01), height (r = 0.32, p < 0.01), and qi-deficiency (r = -0.32, p < 0.01). Mental health displayed correlations with height (r = 0.32, p < 0.01) and qi-deficiency (r = -0.49, p < 0.01). The results of linear regression analyses revealed significant associations between early diet quality and mental health (β = 0.31, p < 0.01), height (β = 0.21, p < 0.01), as well as qi-deficiency (β = -0.26, p < 0.01). Furthermore, when early diet quality was included in the regression model, both height (β = 0.21, p < 0.01) and qi-deficiency (β = -0.35, p < 0.01) emerged as significant mediators in the relationship with mental health.

Conclusion

The mediation model and hypotheses were strongly supported, demonstrating that early diet quality exerted an influence on the mental health of college students through two distinct pathways: height and qi-deficiency. Moreover, the mediating effect of qi-deficiency was found to be more pronounced than that of height in the relationship between early diet quality and mental health among college students.

Juan Bi Tang, a traditional Chinese medicine, for alleviating pain related to arteriovenous fistula in maintenance hemodialysis patients: An interventional pilot study with brief review

Myofascial pain around an arteriovenous fistula (AVF) during hemodialysis (HD) can affect a patient compliance with HD and quality of life. Prolonged use of analgesics is often associated with increased adverse events. Juan Bi Tang (JBT) is an ancient decoction of Chinese traditional medicinal plants commonly used to treat spasms and pain in the shoulder and upper arm, and it is popularly believed to have favorable outcomes in Asian populations. This interventional prospective pilot study was worked to demonstrate the potential of JBT for fistula-associated myofascial pain in HD patients and to prepare for future randomized controlled trials. Eligible patients were enrolled in this study and took JBT to treat fistula-associated myofascial pain for 4 weeks. Pain scores on a visual analogue scale (VAS) were reported at baseline, after a 4-week intervention, and 2 weeks after completion of treatment. The Kidney Disease Quality of Life 36-Item Short Form and a safety laboratory monitor were statistically compared between different time points. A total of 20 patients were selected as eligible participants and completed the intervention and questionnaires. The mean VAS score was significantly reduced after JBT treatment (P < .01). Participants reported improved physical (P < .01) and mental health (P < .05) after treatment. However, only improvements in mental health were preserved 2 weeks after the end of treatment (P < .05). In this study, complementary JBT for HD patients with fistula-related myofascial pain was viable and well tolerated, and it demonstrated the expected effects on pain control.

Mechanism of interventional effect and targets of Zhuyu pill in regulating and suppressing colitis and cholestasis

Zhuyu pill (ZYP) is a traditional Chinese medicine prescription composed of two drugs, Coptis chinensis Franch. and Tetradium ruticarpum (A. Jussieu) T. G. Hartley, and is commonly used in the clinical treatment of diseases of the digestive system. However, the mechanism underlying the effect of ZYP on colitis remains unclear. In this study, a colitis rat model was induced with 2,4,6-trinitro-benzenesulfonic acid (TNBS, 100 mg/kg) and treated with ZYP (low dose: 0.6 g/kg, high dose: 1.2 g/kg). Disease activity index, colonic weight index, and weight change ratio were used to evaluate the model and efficacy. LC-MS and 16S rRNA gene sequencing were used to measure differences in fecal metabolism and microorganism population among the control, model, low-dose ZYP, and high-dose ZYP groups. To elucidate the mechanism of interventional effect of ZYP, Spearman correlation analysis was used to analyze the correlation between fecal metabolism and fecal microbial number. High-dose and low-dose ZYP both exhibited significant interventional effects on colitis rat models, and high-dose ZYP produced a better interventional effect compared with low-dose ZYP. Based on a metabolomics test of fecal samples, significantly altered metabolites in the model and high-dose ZYP treatment groups were identified. In total, 492 metabolites were differentially expressed. Additionally, sequencing of the 16S rRNA gene in fecal samples revealed that the high-dose ZYP could improve TNBS-induced fecal microbiota dysbiosis. Ultimately, changes in tryptophan metabolism and Firmicutes and Gammaproteobacteria populations were detected after ZYP treatment in both colitis and cholestasis. Therefore, we conclude that tryptophan metabolism and Firmicutes and Gammaproteobacteria populations are the core targets of the anti-inflammatory effect of ZYP. These findings provide a scientific basis for further investigation of the anti-inflammatory mechanism of ZYP in the future.

Qi-Deficiency Related Increases in Disease Susceptibility Are Potentially Mediated by the Intestinal Microbiota

Qi-deficiency (QX) is thought to promote the body's susceptibility to disease, but the underlying mechanism through which this occurs is not clear. We surveyed the traditional Chinese medicine constitution (TCMC) of healthy college students to identify those that were PH (balanced TCMC constitution) and QX (unbalanced TCMC constitution). We then used high-throughput sequencing of the 16SrRNA V3-4 region in fecal microbiota samples to identify differences between those obtained from PH and QX individuals. Our results demonstrated that the alpha diversity of QX samples was significantly lower than that of PH samples (p < 0.05) and that beta diversity was remarkably different in QX and PH samples. Four and 122 bacterial taxa were significantly overrepresented in QX and PH groups, respectively. The genera Sphingobium, Clostridium, and Comamonas were enriched in the QX group and had a certain pathogenic role. The QX group also showed a statistically significant lack of probiotics and anti-inflammatory bacteria such as Bifidobacterium and Bdellovibrio. The functional potential of QX bacterial taxa was reduced in fatty acid metabolism and butanoate metabolism. We contend that the imbalanced intestinal microbiota in QX and the following functional changes in metabolism influence immunity and energy metabolism, which could increase susceptibility to disease.

Acupuncture Application in Chronic Kidney Disease and its Potential Mechanisms

Chronic kidney disease (CKD) is an increasing major public health problem worldwide. The number of CKD patients on hemodialysis is growing rapidly as well. Acupuncture technique is one of the traditional Chinese medicine methods and has been used in a variety of diseases. Nowadays, the clinical application of acupuncture technique for CKD patients has become the focus for its effectiveness and security. In this paper, we will review the therapeutic effects and mechanisms of different acupuncture techniques for CKD patients. In patients with CKD, acupuncture improves renal function, reduces proteinuria, controls hypertension, corrects anemia, relieves pain, and controls many hemodialysis-related complications such as uremic pruritus, insomnia and fatigue. The mechanisms are related to the regulation of sympathetic nerve and the activation of bioactive chemicals. In conclusion, acupuncture is proved to be beneficial for CKD patients. More research, however, is needed to verify the potential mechanisms.

Treatment of intradialytic hypotension with an herbal acupoint therapy in hemodialysis patients: A randomized pilot study

OBJECTIVE

Hypotension during hemodialysis (HD) is the most common complication that negatively affects the quality of life of patients. The objective of the current study was to evaluate the preliminary efficacy and safety of herbal acupoint therapy (HAT) for intradialytic hypotension (IDH).

METHODS

A randomized, placebo-controlled trial was performed in 32 HD patients to determine whether HAT was more effective than a sham treatment for the treatment of IDH. The outcomes were frequency of IDH episodes and number of nursing interventions during HD sessions, pre- and post-dialysis BP, subjective change in fatigue as measured by the Visual Analogue Scale (VAS), and recovery time from fatigue after dialysis at the 0th and 4th week. Data analyses were performed using per-protocol population.

RESULTS

In all, 27 patients (84%) completed the entire study. At the end of the intervention, the patients in the HAT group were found to have a significantly lower frequency of IDH episodes, fewer nursing interventions, a lower intervention failure rate, and earlier discontinuation of dialysis than those in the sham group (p < .05). The improvement in degree of fatigue (p = .001) was greater and recovery time from fatigue after dialysis (p = .03) was shorter in the group treated with HAT than in the sham group. HAT was safe, with 2 withdrawal cases due to local erythema caused by the patch.

CONCLUSIONS

HAT appears to be safe and efficacious for improving IDH-related symptoms and intervention in HD patients. Larger studies are needed to confirm the benefit of this technique for IDH.
