Hydroxysafflor yellow a confers neuroprotection against acute traumatic brain injury by modulating neuronal autophagy to inhibit NLRP3 inflammasomes.

ETHNOPHARMACOLOGICAL RELEVANCE: Hydroxysafflor yellow A (HSYA) is the principal bioactive compound isolated from the plant Carthamus tinctorius L. and has been reported to exert neuroprotective effects against various neurological diseases, including traumatic brain injury (TBI). However, the specific molecular and cellular mechanisms underlying HSYA-mediated neuroprotection against TBI are unclear. AIM OF THE STUDY: This study explored the effects of HSYA on autophagy and the NLRP3 inflammasome in mice with TBI and the related mechanisms. MATERIALS AND METHODS: Mice were subjected to TBI and treated with or without HSYA. Neurological severity scoring, LDH assays and apoptosis detection were first performed to assess the effects of HSYA in mice with TBI. RNA-seq was then conducted to explore the mechanisms that contributed to HSYA-mediated neuroprotection. ELISA, western blotting, and immunofluorescence were performed to further investigate the mechanisms of neuroinflammation and autophagy. Moreover, 3-methyladenine (3-MA), an autophagy inhibitor, was applied to determine the connection between autophagy and the NLRP3 inflammasome. RESULTS: HSYA significantly decreased the neurological severity score, serum LDH levels and apoptosis in mice with TBI. A total of 921 differentially expressed genes were identified in the cortices of HSYA-treated mice with TBI and were significantly enriched in the inflammatory response and autophagy. Furthermore, HSYA treatment markedly reduced inflammatory cytokine levels and astrocyte activation. Importantly, HSYA suppressed neuronal NLRP3 inflammasome activation, as indicated by decreased levels of NLRP3, ASC and cleaved caspase-1 and a reduced NLRP3+ neuron number. It increased autophagy and ameliorated autophagic flux dysfunction, as evidenced by increased LC3 II/LC3 I levels and decreased P62 levels. The effects of HSYA on the NLRP3 inflammasome were abolished by 3-MA. Mechanistically, HSYA may enhance autophagy through AMPK/mTOR signalling. CONCLUSION: HSYA enhanced neuronal autophagy by triggering the AMPK/mTOR signalling pathway, leading to inhibition of the NLRP3 inflammasome to improve neurological recovery after TBI.

Intervention Effect of Traditional Chinese Medicine Hot Pressing Combined with Health Education on the Adolescent's Visual Fatigue.

To explore the intervention effect of traditional Chinese medicine hot pressing combined with health education in adolescents with asthenopia, 92 adolescents with asthenopia admitted to the outpatient department of Guangming Traditional Chinese Medicine Hospital in Pudong New Area from October 2019 to January 2021 were selected and randomly divided into two groups: the control group and the test group, each with 46 cases. Both received health education. The control group was given sodium hyaluronate eye drops, and the test group was given traditional Chinese medicine hot ironing technique intervention. After 2 courses of treatment, the scores of visual fatigue symptoms, clinical curative effect, and eye refractive power of the two groups were observed. The satisfaction of treatment was compared between the two groups. The scores of asthenopia of the two groups were compared at 6 months after intervention. After the intervention, the scores of visual fatigue symptoms in the control group and the test group were reduced after one or two courses of treatment (control group: t = 4.167, 6.318, and P=0.027, 0.010; test group: t = 4.820, 6.834, and P=0.013, <0.001). The scores of asthenopia symptoms of the trial group after the intervention for one and two courses were significantly lower than those of the control group (P < 0.05); the total clinical effective rate of the trial group was 93.48%, which was significantly higher than that of the control group (80.43%). The difference between the groups was statistically significant (P < 0.05); the left and right eyes of the control group did not change significantly before and after the intervention (P > 0.05). After the intervention, the left and right eyes of the paper group were significantly reduced (P < 0.05). After the intervention, the difference of the two groups in the refractive power of the left and right eyes was statistically significant (P < 0.05). After treatment, the satisfaction of the experimental group was significantly higher than that of the control group (P < 0.05). After 6 months, there was no significant change in the visual fatigue score of the experimental group, while the visual fatigue score of the control group increased significantly. The traditional Chinese medicine ironing combined with health education intervention can improve the symptoms of adolescents' asthenopia and improve the treatment efficiency. The method is safe, and the operation is convenient. It is worthy of clinical promotion.

Effects of Enalapril on TLR2/NF-κB Signaling Pathway and Inflammatory Factors in Rabbits with Chronic Heart Failure.

Chronic heart failure (CHF) refers to the state of persistent heart failure, which is a complex clinical syndrome of various advanced heart diseases. The toll-like receptor 2 (TLR2)/nuclear transcription factor-κB (NF-κB) signal transduction pathway is one of the pathological mechanisms of CHF. Adriamycin can significantly induce the upregulation of TLR2 expression. Angiotensin-converting enzyme inhibitors (ACEI) are commonly used drugs for the treatment of CHF. In our study, the CHF model was established by injection of doxorubicin into the rabbit ear vein. The effect of enalapril on the TLR2/NF-κB signaling pathway in CHF rabbits has been analyzed and determined. Our research results showed that enalapril reduced the inflammatory response by inhibiting the activation of the TLR2/NF-κB signaling pathway, thereby improving cardiac structure, myocardial remodeling, and cardiac function.

Effects of comprehensive care on psychological emotions, postoperative rehabilitation and complications of colorectal cancer patients after colostomy.

OBJECTIVE: This study aimed to explore the impacts of comprehensive care on psychological emotion, postoperative rehabilitation and complications of colorectal cancer patients after colostomy. METHODS: From August 2018 to February 2020, a total of sixty colorectal cancer patients undergoing colostomy in our hospital were collected and randomly assigned to a control group to receive conventional care and a research group to receive comprehensive care, with 30 patients in each group. The two groups of patients were compared for postoperative recovery, complications, adverse psychological emotions, self-care ability, quality of life, and nursing satisfaction. RESULTS: The first time of exhaust, food intake and the recovery of bowel sound in the research group were markedly earlier than those in the control group. Besides, the research group had notably lower incidence of postoperative complications, lower self-anxiety scale (SAS) and self-depression scale (SDS) scores at discharge, and higher average self-care ability than the control group, as well as higher quality of life score and nursing satisfaction. CONCLUSION: Comprehensive care intervention can promote postoperative recovery of colorectal cancer patients after colostomy, relieve their negative emotions, reduce postoperative complications, improve quality of life and nursing satisfaction, which are all important and make this type of care worthy of promotion in clinical practice.

Epigallocatechin gallate induces chemopreventive effects on rats with diethylnitrosamine­induced liver cancer via inhibition of cell division cycle 25A.

Epigallocatechin gallate (EGCG), the most active monomer in green tea (GT), has demonstrated potential therapeutic and preventive effects on various tumors, including liver cancer. However, the anticancer mechanisms of EGCG in liver cancer remain to be elucidated. The abnormal expression of cell division cycle 25A (CDC25A) has been identified in liver cancer and is closely associated with malignancy and poor prognosis in patients with hepatocellular carcinoma (HCC). The present study used human hepatoma cell lines and rats with diethylnitrosamine (DEN)­induced HCC as models to investigate the association between the effect of EGCG on liver cancer and regulation of the p21waf1/Cip1/CDC25A axis. The results demonstrated that EGCG can inhibit the proliferation of HepG2 and Huh7 cells, reduce the expression of CDC25A and increase the expression of p21waf1/Cip1 in HepG2. In vivo, HCC was induced by DEN in Sprague­Dawley rats. EGCG significantly reduced tumor volume and improved the survival rates of rats with HCC. The expression levels of CDC25A mRNA and protein in liver tissues and the level of serum γ glutamyl transpeptidase in rats treated with EGCG were significantly decreased, while p21waf1/Cip1 mRNA and protein expression levels were increased compared with the HCC group, in the process of DEN­induced HCC. No significant difference in the chemopreventive effects on liver cancer was observed between GT extract and EGCG under an EGCG equivalence condition. Thus, EGCG can suppress human hepatoma cell proliferation and prolong the survival of rats with HCC, and the potential mechanism may be involved in EGCG­induced upregulation of p21waf1/Cip1 and downregulation of CDC25A.

Epigastric pain syndrome: What can traditional Chinese medicine do? A randomized controlled trial of Biling Weitong Granules.

BACKGROUND: Recent research suggests that although prokinetic agents, acid suppressors, and radical treatment for Helicobacter pylori infection may be effective in patients with functional dyspepsia (FD), a large proportion of patients still fail to respond to these treatments or may suffer from severe adverse reactions. Many traditional Chinese medicinal herbs can regulate the status of the entire body and have special advantages in the treatment of functional diseases. The present study was designed to verify the efficacy of Biling Weitong Granules (BLWTG), a traditional Chinese medicinal herbal compound formula, in alleviating epigastric pain syndrome (EPS) in FD patients, in an attempt to provide an effective prescription for the clinical treatment of this disease. AIM: To evaluate the clinical efficacy and safety of BLWTG in treating EPS in patients with FD. METHODS: In this multicenter, stratified, randomized, double-blind, placebo-controlled, parallel group clinical trial, eligible patients were randomized into the BLWTG and placebo groups who were treated for 6 wk. Efficacy indicators including the severity and frequency of EPS and the time to pain resolution and safety indicators including adverse events were observed and compared. RESULTS: The baseline demographic data and clinical characteristics, such as epigastric pain symptoms, pain intensity, and frequency of attacks, were matched between the two groups before randomization. After 6 wk of treatment and after the center effect was eliminated, the epigastric pain was significantly improved in 28.33% and 85.59% of the patients in the placebo and BLWTG groups, respectively (P < 0.05). At 6 wk, the resolution rate of epigastric pain was 15% and 69.49% in the placebo and BLWTG groups, respectively (P < 0.05). The differences of total FD clinical score between these two groups were significant (P < 0.05) at 2, 4, and 6 wk (P < 0.05). The scores of each item and the total score in the Functional Digestive Disorders Quality of Life Questionnaire showed significant differences between the two groups at 6 wk after both the center and interaction effects were eliminated (P < 0.05). There was no significant difference in the incidence of adverse events between the two groups, and no serious adverse event was noted during the observation. CONCLUSION: Compared with placebo, BLWTG markedly improved EPS in FD patients without causing serious adverse reactions.

Niacin ameliorates ulcerative colitis via prostaglandin D2-mediated D prostanoid receptor 1 activation.

Niacin, as an antidyslipidemic drug, elicits a strong flushing response by release of prostaglandin (PG) D2 However, whether niacin is beneficial for inflammatory bowel disease (IBD) remains unclear. Here, we observed niacin administration-enhanced PGD2 production in colon tissues in dextran sulfate sodium (DSS)-challenged mice, and protected mice against DSS or 2,4,6-trinitrobenzene sulfonic acid (TNBS)-induced colitis in D prostanoid receptor 1 (DP1)-dependent manner. Specific ablation of DP1 receptor in vascular endothelial cells, colonic epithelium, and myeloid cells augmented DSS/TNBS-induced colitis in mice through increasing vascular permeability, promoting apoptosis of epithelial cells, and stimulating pro-inflammatory cytokine secretion of macrophages, respectively. Niacin treatment improved vascular permeability, reduced apoptotic epithelial cells, promoted epithelial cell update, and suppressed pro-inflammatory gene expression of macrophages. Moreover, treatment with niacin-containing retention enema effectively promoted UC clinical remission and mucosal healing in patients with moderately active disease. Therefore, niacin displayed multiple beneficial effects on DSS/TNBS-induced colitis in mice by activation of PGD2/DP1 axis. The potential efficacy of niacin in management of IBD warrants further investigation.

[Shen warming Pi strengthening method intervened IBS-D rats: an efficacy assessment].

OBJECTIVE: IBS-D rat model was established to assess the effect of Shen warming Pi strengthening method (SWPSM) for intervening diarrhea-predominant irritable bowel syndrome (IBS-D) by observing rats' general state, stool properties, AWR ranking, and histopathological changes. METHODS: Totally 72 rats were randomly divided into 6 groups, i.e. the normal group, the model group, the high, middle, low dose SWPSM groups, and the control group, 12 in each group. The IBS-D rat model was successfully established referring to AL-Chaer ED's modeling method. After modeling high, middle, and low dose SWPS Recipe boil-free granules were given by gastrogavage to rats in corresponding treatment groups. Sishen Pill boil-free granule was given by gastrogavage to those in the control group. Equal volume of normal saline was given by gastrogavage to rats in the model group. The medication lasted for 2 weeks. Rats' general state, stool properties, abdominal withdrawal reflex (AWR) ranking, and histopathological changes were observed. RESULTS: After treatment, the general state of all rats got im- provement to various degrees. The improvement in the high and middle dose SWPS Recipe groups were superior to that in the low dose SWPS Recipe group and the control group (P < 0.05). There was no statistical difference in the growth rate between after and before treatment in each group (P > 0.05). Compared with the model group and the low dose SWPS Recipe group, the defecation amount within 4 h was less in the high and middle dose SWPS Recipe groups and the control group (P < 0.05). The Bristol ranking score, average ranking of loose stool, ratio of dry stool and wet stool were lower in the high and middle dose SWPS Recipe groups than in the control group and the low dose SWPS Recipe group (P < 0.05). The AWR ranking score was lower in the high and middle dose SWPS Recipe groups than in the control group when the volume of balloon dilation was 1.5 mL. There was no organic change of histological or morphological observation. CONCLUSIONS: High sensitive IBS-D model was proved to be reliable. SWPSM could reduce the quantity of stools, lower Bristol ranking score, average ranking of loose stools as well as ratios of dry stool and wet stool, contributing to reducing the high sensitivity of rats' visceral organs to some extent.

[Effect of pungent dispersion bitter purgation method on the esophageal mucosal intercellular space of reflux esophagitis model rats].

OBJECTIVE: To observe the effect of pungent dispersion bitter purgation method (PDBPM) on the esophageal mucosal intercellular space of reflux esophagitis (RE) model rats. METHODS: Totally 100 Wistar rats were randomly divided into the control group, the model group, the Western medicine group (WM), the Chinese medicine group (CM), 25 rats in each group. Rats in the control group only received switch operation. Rats in the rest three groups received modified partial cardia muscle incision combined pylorus ligation of external parts to prepare the RE rat model. Starting from the 3rd day after operation, WM mixture (Motilium 3. 2 mg/kg + Omeprazole Capsule 4.3 mg/kg + Hydrotalcite Tablet 161.4 mg/kg) was administered by gastrogavage to rats in the WM group. Rats in the CM group was administered by gastrogavage with Modified Banxia Xiexin Decoction (5.7 g/kg), 2.5 mL each time, twice daily for 14 consecutive days. Equal volume of normal saline was administered by gastrogavage to rats in the control group and the model group. On day 7 and 14, the lower esophagus pH value, general specimen of mucosa and histopathologic changes were observed. Intercellular spaces of esophageal epithelium were measured for a control study. RESULTS: Compared with the same group at day 7, the lower esophagus pH value increased at day 14 (P < 0.01); the naked eye integral of esophageal mucosa and intercellular spaces of esophageal epithelium also decreased at day 14 in the CM group and the WM group (P < 0.05). Compared with the control group at the same time point, the lower esophagus pH value decreased in the model group (P < 0.01). The naked eye integral of esophageal mucosa, and intercellular spaces of esophageal epithelium increased in the model group with increased intercellular spaces (P < 0.01). Compared with the model group at the same time point, the lower esophagus pH value increased and the naked eye integral of esophageal mucosa decreased in the CM group and the WM group at day 7 and 14 (P < 0.01). Intercellular spaces of esophageal epithelium of RE model rats at day 14 was lower in the CM group and the WM group than in the model group (P < 0.01). Compared with the WM group, the lower esophagus pH value decreased at day 7 in the CM group (P < 0.05); the naked eye integral of esophageal mucosa and intercellular spaces of esophageal epithelium decreased at day 14 in the CM group (P < 0.05). CONCLUSIONS: PDBPM had favorable treatment effect on RE model rats. The therapeutic effect was more obvious along with the therapeutic course went by. Its mechanism might be achieved through good repair effect on damaged mucosa, increasing the pressure of esophageal sphincter, and inhibiting gastric acid.
