RESUMO

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.

RESUMO

Objective: As an important food therapy product with traditional Chinese medicine (TCM) applications, donkey-hide gelatin (Asini Corii Colla, ACC) has been used for thousands of years. However, till now few effective strategy had been proposed to distinguish ACC from other animal hide gelatins, especially closely related horse- and mule-hide gelatins, which was an embarrassment of ACC quality control. Methods: Combined mass spectrometry and bioinformatic methods have been applied to identify and verify two ACC-specific peptides (Pep-1 and Pep-2) capable of distinguishing ACC from other closely related animal gelatins with high selectivity. Results: It confirmed that these two peptides could be not only used for distinguishing ACC from highly homologous horse-hide and mule-hide gelatins as well as other animal hide gelatins. Conclusion: The present study provides a simple method for species-specific peptides discovery, which can be used for assessing the quality of animal gelatin products, and ensure they are authenticable and traceable.

RESUMO

Objective To observe the clinical efficacy of acupuncture at the three nasal acupoints plus bloodletting at Suliao (GV 25) in treating rosacea.Method Sixty rosacea patients were randomized into a treatment group and a control group, 30 cases each. The treatment group was intervened by acupuncture at the three nasal acupoints plus bloodletting at Suliao (GV 25), while the control group was intervened by ordinary medication. The skin lesion scores of the two groups were observed before and after 4-week treatment, and the clinical efficacies were also compared. Result The skin lesion scores were significantly changed after respectively 2, 3 and 4 weeks of treatment in both groups (P<0.05). The skin lesion scores in the treatment group were significantly different from those in the control group respectively after 2, 3 and 4 weeks of treatment (P<0.05). The total effective rate was 93.3% in the treatment group versus 73.3% in the control group, and the between-group difference was statistically significant (P<0.05). Conclusion Acupuncture at the three nasal acupoints plus bloodletting at Suliao (GV 25) is an effective approach in treating rosacea.

RESUMO

Objective:To observe the clinical efficacy of fire-needle therapy in treating deglutition disorders due to pseudobulbar palsy in the remission stage of stroke.Methods:Sixty-two eligible subjects were divided into a fire-needle group and a rehabilitation group by a simple randomization method at a ratio of 1:1.The two groups received same basic intervention;in addition,the fire-needle group received fire-needle treatment,while the rehabilitation group received rehabilitation training.The two groups of subjects all received a 3-week treatment and were evaluated by the dysphagia severity rating scale (DSRS),modified Mann assessment of swallow ability (MMASA) and Kubota Toshio swallow test (KTST) before and after the intervention.The complications and adverse events occurred during the trial were recorded.The data were statistically analyzed.Results:At the third week,the DSRS,MMASA and KTST scores changed significantly compared with the baseline in both groups (P<0.05),and the changes in the fire-needle group were more significant than those in the rehabilitation group (P<0.05).The between-group comparison at the third week showed that the therapeutic efficacy in the fire-needle group was superior to that in the rehabilitation group (P<0.05).Conclusion:Fire-needle therapy can obviously change the DSRS,MMASA and KTST scores in pseudobulbar palsy in the remission stage of stroke,and significantly enhance the therapeutic efficacy of the treatment of deglutition disorders in this stage.
