RESUMEN
Depression is a common psychiatric disease that seriously affects the physical and mental health and quality of life of patients， and has become one of the major global disease burdens. The etiology of depression is intricate， and despite extensive research， its pathogenesis remains inconclusive， resulting in various hypotheses of its onset mechanisms. Presently， the primary approach for clinically treating depression involves the utilization of selective inhibitors targeting the reuptake of monoamine neurotransmitters within the central nervous system. However， these drugs are generally characterized by delayed onset of action， limited efficacy and obvious resistance. Recently， researchers have gradually turned their attention to the development of antidepressant drugs with novel mechanisms. Notably， as a category of abundantly available active ingredients in Chinese medicine， numerous pharmacological studies have demonstrated that oligosaccharides and polysaccharides possess promising antidepressant properties， such as Morindae Officinalis Radix oligosaccharides， Polygalae Radix oligosaccharide esters， Poria polysaccharides and Astragali Radix polysaccharides. Their pharmacological mechanisms are various， including enhancing the levels of monoamine neurotransmitters in the brain， inhibiting the hyperactivation of the hypothalamic-pituitary-adrenal axis（HPA axis）， increasing the expression of neurotrophic factors（NTF）， regulating immune-inflammatory responses and modulating the microbiota-gut-brain axis. Therefore， oligosaccharides and polysaccharides from Chinese medicine have become a vital source of safe and effective novel antidepressant candidates due to the potential to improve depression through integrated regulatory effects. This article aims to provide a comprehensive and systematic review of recent progress to contribute to the elucidation of the mechanisms underlying the antidepressant effects of oligosaccharides and polysaccharides derived from Chinese medicine.
RESUMEN
BACKGROUND: Foot reflexology has been considered an important complementary therapy for many health-related symptoms, especially for some chronic conditions such as anxiety, stress, pain and fatigue. Some studies also showed that foot reflexology had a significant effect on functional constipation, whereas some studies did not. The effect of foot reflexology on functional constipation remains controversial. Therefore, an evidence-based systematic review and meta-analysis of randomised controlled trials were conducted to investigate the effect of foot reflexology on functional constipation. METHODS: Randomised controlled trials were identified by searching five electronic databases and hand-searching eligible reference lists. Studies that reported the effect of foot reflexology on functional constipation were included. Two reviewers performed the study screening, quality assessment and data extraction. Any discrepancy was discussed with a third reviewer. Quantitative synthesis was conducted for the same outcome measurements by calculating weighted risk ratios. RESULTS: A total of 203 records were identified, of which seven were eligible. Overall, foot reflexology significantly increased the curative ratio, with a pooled risk ratio of 1.27 (95% CI: 1.16, 1.40, p < 0.00001). Three trials compared the improvement of constipation-related symptoms after intervention in both the experimental and control groups by evaluating the constipation-related symptom scores. The results all showed that foot reflexology can effectively improve constipation-related symptoms. However, one trial reported that foot reflexology had no significant effect on stool frequency and stool consistency. Two studies indicated that foot reflexology significantly reduced the recurrence rate of functional constipation. One study reported the effect of foot reflexology on compliance with the toilet training, diet and motivation. Nevertheless, no significant improvement was detected. CONCLUSION: Foot reflexology is an effective complementary therapy for treating functional constipation. However, because of the small number of included studies and their small sample sizes, the current evidence was insufficient to support the effectiveness of foot reflexology in reducing the recurrence rate, improving the constipation-related symptom, and compliance with toilet training, diet and motivation. Randomised controlled trials with long-term follow-up are needed for further investigation.

A large number of studies have shown that berberine exerts an anti-tumor effect mainly by inhibiting cancer cell proliferation, inducing cancer cell death, inhibiting cancer cell metastasis and invasion, regulating the expression of endogenous oncogenes and tumor suppressor genes, affecting the activity of cancer-related enzymes, exerting an anti-oxidative stress effect, correcting abnormal glucose metabolism, and inhibiting the activity of nuclear factor-kappa B and its pathways. In vivo and in vitro studies have shown than berberine has a marked clinical effect in the treatment of hepatocellular carcinoma with various pharmacological actions and molecular regulatory mechanisms. This article reviews the role and mechanism of berberine, an active component of traditional Chinese medicines including Coptis chinensis, in the treatment of hepatocellular carcinoma and thus reveals the clinical effect of berberine in the treatment of hepatocellular carcinoma. In future, new dosage forms should be developed to improve its bioavailability and form effective therapeutic regimens for clinical application.
RESUMEN
Aiming at the present situation that the students of traditional Chinese college usually have relatively weak background knowledge in western medicine, we proposed that pharmacological teaching should improve teaching quality by explaining the profound knowledge in simple terms, focusing on key-point knowledge, contacting clinical practice ,and making full use of multimedia.
