RESUMEN
BACKGROUND: Yoga is gradually being explored as a potential complementary intervention in addition to psychiatric drugs for schizophrenia. However, there are conflicts on the efficacy of yoga for schizophrenia. This meta-analysis was aimed to evaluate the association of yoga intervention with reductions on clinical symptoms and improvements in quality of life (QoL) as well as social functioning among schizophrenia. METHOD: Systematic literature search was undertaken to identify all RCTs that compared yoga with active or passive controls for patients with schizophrenia from inception to July 2023. The outcomes were measurements of positive symptoms, negative symptoms, QoL and social functioning. Random-effects models were performed to calculate the effect sizes in the standardized mean differences reporting as Hedges' s g statistic. RESULTS: 19 studies enrolling 1274 participants with schizophrenia were included. Yoga had a medium effect on positive symptoms in the short term (Hedges's g = 0.31) and small effect in the long term (Hedges's g = 0.18). Medium significant effects were also found on negative symptoms in both the short term (Hedges's g = 0.44) and the long term (Hedges's g = 0.35). Yoga had a significant impact on improving both total QoL (Hedges's g = 0.34) and social functioning (Hedges's g = 0.45) with medium effect sizes. CONCLUSIONS: Yoga was associated with significant reductions on negative and positive symptoms, and significant improvements in QoL as well as social functioning in patients with schizophrenia. Future research should explore the long-term efficacy of yoga for schizophrenia, encompassing more diverse populations.

PURPOSE: Transcutaneous electrical acupoint stimulation (TEAS) is an innovative choice for postoperative pain management. However, the safety and effectiveness of this traditional Chinese medicine (TCM) therapy for patients who underwent gastrectomy is largely unknown. So, the purpose of this study is to evaluate the safety and effectiveness of TEAS for patients who underwent gastrectomy. PATIENTS AND METHODS: We recruited 96 patients with gastric cancer from May 2019 to November 2019; 82 patients were enrolled, and 81 patients completed. Patients were randomly assigned to TEAS group (TG) received TEAS on postoperative day (POD) 1-3 or control group (CG) at a 1:1 ratio. The primary outcomes were pain score and consumption of analgesics. The secondary were the time of first postoperative flatus and defecation, frequency of postoperative nausea, vomiting, distention, diarrhea, comfort of semi-fluid diet, Clavien-Dindo grade (C-D grade) and length of postoperative day. We performed hematological analysis to explore the possible mechanisms. RESULTS: Overall, 81 patients were enrolled included in the analysis. Compared with CG, pain scores in TG were lower on POD 1-5 (average: 2.55±0.21 vs 3.10±0.42, P<0.001), and the use rate of opioids was lower (43.9 vs 75.0, P=0.004); time of first postoperative flatus (55.63±16.74 vs 72.60±20.92, P<0.001) and defecation (72.20±16.24 vs 95.78±17.75, P<0.001) were shorter; the frequency of nausea were fewer (1.88±1.09 vs 2.58±0.77, P=0.029) and patients were more comfortable with semi-fluid diet (7.63±0.63 vs 6.93±0.69, P<0.001); among the hematologic results, ß-endorphin (ß-End), interleukin-2 (IL-2), motilin (MTL) on POD 3, POD 5 were lower, 5-hydroxytryptamine (5-HT), interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α) were higher. And no adverse event was reported. CONCLUSION: TEAS can relieve postoperative pain and promote the recovery of gastrointestinal function. Consequently, it can be an adjunctive therapy to enhance postoperative recovery for patients after gastrectomy.
RESUMEN
The phenotypes of Lepidium meyenii (Maca) relate to their difference of chemical compositions and biological activities. Essential oils, lipids and polysaccharides are the main active components in Maca, all of which showed potential antioxidant effect. The essential oil, lipid and polysaccharide compositions were analyzed by GC-MS after the samples were properly pre-treated from yellow, red and black Maca. The antioxidant properties of the three types of components were examined using the DPPH scavenging assay. The correlation of main compositions and the antioxidant activities was evaluated by a statistical method. In Maca essential oil, lipid and polysaccharide samples, thirty volatile compounds, twenty-nine fatty acids and six monosaccharides had been detected, in which benzeneacetonitrile, unsaturation fatty acids and mannose were predominant ingredients, respectively. In three types of components, the DPPH scavenging effect of essential oil was stronger. All of black Maca essential oil, lipid and polysaccharide showed higher effect than yellow and red phenotype. The total activity of the three types of components showed about 60% of the antioxidant activity of entire Maca. Canonical correlation analysis (CCA) results showed that four essential oils, three fatty acids and four monosaccharaides were positively related to the antioxidant activity. The research is helpful to address the quality attributes and the comprehensive application of different phenotypes of Maca.

Glycyrrhetinic acid (GA) is a natural active component from licorice, which is broadly used in traditional Chinese medicine. Lots of glycyrrhetinic acid receptors (GA-R) are proved to locate on the surface of liver cells. Many reports about the hepatocellular carcinoma (HCC) treatment were dependent on GA modified carriers. However, the reality of GA-R in HCC cells was not clear. In this paper, 18ß-glycyrrhetinic acid (18ß-GA) was labeled with fluorescence (FITC) by chemical synthesis. Together with the binding effect of fluorescence labeled glycyrrhetinic acid (FITC-GA), the competitive action of 18ß-GA with GA-R was investigated in HCC cells. The results showed that in HepG2 cells, 18ß-GA and FITC-GA presented similar cytotoxicity. The specific binding saturation of GA showed the dissociation constant (Kd) was 7.457±2.122pmol/L and the maximum binding counts (Bmax) was 2.385±0.175pmol/2.5×106 cells, respectively. FITC-GA bound to cytomembrane specifically and 18ß-GA competed to bind the sites significantly in HepG2 cells. Therefore, there is binding effect between fluorescence labeled GA and GA-R. The GA-R on HCC cells is confirmed as expected, which provides a useful reference of active target modified by GA and a novel approach for receptors and ligands study.

The adverse drug reaction (ADR) of traditional Chinese medicine (TCM) has been concerned nowadays. Some bans were published to limit their use abroad. There wasn't a feasible criterion to reply to the ADR of TCM yet in China. The ADR of 6 kinds of typical TCM which state attached importance to was chosen to discuss. Based on the retrospect investigation, the objectivity of ADR was explored in this study.

OBJECTIVE: To study and analyze the antibacterial effects of different extracts from Radix Isatis. METHODS: Staphylococcus aureus was used as the studied object in the experiment. Antibacterial effects of extracts from Radix Isatis were observed by thermocalrimetry on Staphylococcus aureus, together with common pharmacological experiments. RESULTS: The total extract, ethyl acetate (EtOAc) extract, n-butylalcohol (nBuOH) extract, chloroform (CHCl(3)) extract and petroleum (P.E.) extract had antiviral effects to some extent while the residue after extracting had no antibacterial activity. The potency of antiviral activity among them was as follows: nBuOH extract > EtOAc extract > CHCl(3) extract > total extract > P.E. extract. CONCLUSION: The antibacteriall effects of Radix Isatis were not limited to any active portion, showing that Radix Isatis exerts its antibacterial effects by cooperation of different active fractions in varied ways.
