RESUMO
This study aims to assess the safety and efficacy of Shumian Capsules in the treatment of insomnia. Randomized controlled trial(RCT) about Shumian Capsules for insomnia were retrieved from databases. RevMan 5.4 was used for statistical analysis. A total of 23 articles were included, involving 2 621 patients. Meta-analysis showed that Shumian Capsules had advantages in the treatment of insomnia(RR=1.07, 95%CI[1.03, 1.10], P=0.000 2) and insomnia with depression(RR=1.13, 95%CI[1.02, 1.25], P=0.02) in terms of total response rate. Shumian Capsules had advantages in the treatment of insomnia(MD=-0.75, 95%CI[-1.33,-0.17], P=0.01) and insomnia with depression(MD=-2.51, 95%CI[-2.96,-2.06], P<0.000 01) in terms of PSQI score. The incidence of adverse events in the Shumian Capsules(RR=0.33, 95%CI[0.24, 0.46], P<0.000 01) and Shumian Capsules + conventional western medicine(RR=0.71, 95%CI[0.54, 0.95], P=0.02) was lower than that in the conventional wes-tern medicine alone. In addition, Shumian Capsules had an advantage in treating insomnia complicated with depression in terms of HAMD score(P<0.000 1) and reducing the serum levels of 5-HT, TSH, T3, and T4 in insomnia patients(P<0.05). The quality of evidence was mostly medium or low. The studies demonstrate that Shumian Capsules is effective and safe for treating insomnia, which may be related to the mechanism of lowering the levels of 5-HT, TSH, T3, and T4 in the serum. In view of the quality of evidence, the application of Shumian Capsules should be considered after comprehensive evaluation in clinical practice.

The application of reclaimed water has been recognized as the key approach for alleviating water scarcity, while its low quality, such as high nitrogen content, still makes people worry about the corresponding ecological risk. Herein, we investigated the feasibility of removing residual nitrate from reclaimed water by applying Spirulina platensis. It is found that 15 mg/L total nitrogen could be decreased to 1.8 mg/L in 5 days, equaling 88.1 % removal efficiency under the optimized conditions. The deficient phosphorus at 0.5-1.0 mg/L was rapidly eliminated but was already sufficient to support nitrate removal by S. platensis. The produced ammonia is generally below 0.2 mg/L, which is much lower than the standard limit of 5 mg/L. In such a nutrient deficiency condition, S. platensis could maintain biomass growth well via photosynthesis. The variation of pigments, including chlorophyll a and carotenoids, suggested a certain degree of influences of illumination intensity and phosphorus starvation on microalgae. The background cations Cu2+ and Zn2+ exhibited significant inhibition on biomass growth and nitrate removal; thus, more attention needs to be paid to the further application of microalgae in reclaimed water. Our results demonstrated that cultivation of S. platensis should be a very promising solution to improve the quality of reclaimed water by efficiently removing nitrate and producing biomass.

The present study aimed to explore the targets and mechanism of Mailuo Shutong Pills(MSP) in the treatment of ischemic stroke by network pharmacology, and verify the key targets through molecular docking and animal experiment, so as to provide a theoretical basis for the clinical application of MSP. The main chemical ingredients of MSP were obtained by searching against the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and relevant literature. The potential targets of the ingredients of MSP in treating ischemic stroke were obtained from SwissTargetPrediction and DisGeNET. Protein-protein interaction(PPI) network was analyzed in STRING and plotted in Cytoscape. Gene Ontology(GO) annotation and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis were carried out with DAVID. Molecular docking was simulated to determine the binding activity of active ingredients to key targets in AutoDock Vina. The mouse model of ischemic stroke was established. The mice were classified into a sham group, a model group, and an MSP group. After the administration, cerebral infarction volume was detected by 2,3,5-triphenyltetrazoliumchloride(TTC) staining, and Western blot was performed to determine the levels of phosphatidylinositol 3-kinase(PI3 K), protein kinase B(AKT), nuclear factor-κB(NF-κB) and their phosphorylated proteins. A total of 222 ingredients of MSP were screened out, including beta-sitosterol, quercetin, licochalcone B, and lupiwighteone, which acted on 701 targets. Totally 1 079 targets associated with ischemic stroke were retrieved, among which 192 common targets were shared by MSP and ischemic stroke. The key targets included AKT1, phosphatidylinositol 3-kinase catalytic subunit alpha(PIK3 CA), phosphatidylinositol 3-kinase regulatory subunit 1(PIK3 R1), and nuclear factor-κB p65 subunit(RELA), which were mainly involved in PI3 K/AKT, tumor necrosis factor(TNF), and NF-κB signaling pathways. The results of molecular docking revealed that PI3 K, AKT1, and RELA had good binding ability to the active ingredients of MSP. The animal experiment results showed that compared with the model group, MSP decreased cerebral infarction volume, down-regulated the expression of p-NF-κB, and up-regulated the expression of p-PI3 K and p-AKT in mouse brain. In summary, the active ingredients in MSP may treat cerebral injury by activating PI3 K/AKT signaling pathway and inhibiting NF-κB signaling pathway.

By searching the randomized controlled trials (RCTs) of acupuncture and moxibustion from CNKI since its inception date to december 31 of 2019, the development status and hot trend of RCTs of acupuncture and moxibustion in China were summarized. The CiteSpace and VOSviewer software were used to perform keyword co-occurrence analysis, clustering analysis, time-zone analysis and citation-burst analysis, and visual map was drawn. As a result, a total of 60 995 articles were included, which were published in 1027 academic journals with 1787 keywords. The publication date was from 1975 to 2019. During the past 45 years, the publications of RCTs on acupuncture and moxibustion had shown an overall growth trend with characteristics of the times. The RCTs of manual acupuncture ranked the top, and its proportion of publications every 5 years was stable in the past 30 years. Since 1994, the hot words such as electroacupuncture, warming needling, auricular point sticking and various acupoint therapies had emerged; meanwhile, the spectrum of diseases had broadened, and an evolutionary trend corresponding to therapies and disease systems had been formed. In recent decade, the RCTs using moxibustion therapy have increased significantly, and the hot words such as "sub-health" "winter diseases being treated in summer" and "acupoint application/ moxibustion during the dog days" had indicated that acupuncture clinical research was further inclined to the field of chronic disease prevention and health services, which was in line with social development and the needs of the times.

OBJECTIVE: To analyze the literature knowledge structure and acupoint matching rules of acupuncture for depression. METHODS: The articles regarding acupuncture for depression published from January 1 of 1984 to October 19 of 2020 were searched in CNKI database. CiteSpace5.7.R2 software was used to import the literature data, and the keyword cluster analysis, emergence analysis and time-zone analysis of articles and acupoints were conducted, and the map of scientific knowledge was draw. RESULTS: A total of 3524 articles were included to the knowledge structure analysis, while 601 articles into the acupoint matching rules analysis. There were 13 keyword clusters of acupuncture for depression, with "post-stroke depression" and "electroacupuncture treatment" as high-frequency keywords, and "electroacupuncture treatment" and "Hamilton depression scale" had high centrality, and "electroacupuncture treatment" had the highest emergence intensity. The keywords such as "electroacupuncture treatment" and "Hamilton depression scale", etc. appeared the earliest, followed by "post-stroke depression", "fluoxetine" and "auricular point therapy", etc. According to traditional Chinese medicine theory, acupoint keywords were divided into four clusters: â core acupoint, â¡replenishing-spleen and dispelling phlegm, dispersing-liver and relieving depression, reinforcing qi and nourishing blood, â¢back-shu points, five-zhi points, â£inducing-resuscitation and opening-closes. CONCLUSION: The main knowledge structure of acupuncture for depression includes five parts: treatment method, depression type, TCM-related diseases, literature type and curative effect index. Clinical acupoint matching should adhere to the principle of "focusing the disease before syndrome" and "combination of disease and syndrome", and treatment should be modified for the syndromes of phlegm stagnation blocking, liver-stagnation and qi-stagnation, and deficiency of both qi and blood.

ETHNOPHARMACOLOGICAL RELEVANCE: TG-decoction (Tiao Geng decoction) is the extract of a Chinese herb mixture that has been used for treating menopausal symptoms for over 30 years. We have previously reported anti-aging and anti-oxidative effects of the TG-decoction on hypothalamic neurons in ovariectomized (OVX) rats. AIM OF THE STUDY: The present study further investigates the effects of TG-decoction on the prevention of aging-related ultrastructural changes in menopausal hypothalamic neurons and the likely molecular mechanism. MATERIALS AND METHODS: A total of 120 four-month-old female SPF Sprague Dawley rats were divided into six groups. Five groups were ovariectomized (OVX) and one group served as a sham control. Three OVX groups received TG-decoction at three different doses. The remaining two OVX groups served as positive and negative controls by receiving estradiol valerate and saline solution. The sham group received saline. After one month, aging-related ultrastructural alterations in hypothalamic neurons were evaluated using transmission electron microscopy. Nissl staining was used to assess the pathomorphological changes of the hypothalamic neurons. Cell apoptosis was evaluated by TUNEL. Expression of Bcl-2 family genes was studied using qRT-PCR. Expression of the apoptosis-related proteins ASK1, MKK7, JNK, c-Jun, Bax, Casp3 and Bcl-2 was studied using western blotting. RESULTS: Ovariectomy of female rats led to visible damage and aging-like alterations in the mitochondria and endoplasmic reticulum as well as large deposits of lipofuscin in hypothalamic tissue. TG-decoction treatment prevented this visible damage and lipofuscin deposition, increased the number of nerve cells and normally-shaped Nissl bodies, and reduced the number of TUNEL-positive cells. Expression of Bcl-2 gene was increased, while Bax gene reduced. Expression of the proteins ASK1, MKK7, JNK, c-Jun, Bax and Casp3 was reduced, while that of Bcl-2 was increased. CONCLUSION: TG-decoction reduces aging-related ultrastructural changes in hypothalamic neurons, likely by suppressing ASK1/MKK7/JNK-mediated apoptosis in neuronal mitochondria or nuclei.

BACKGROUND: Cyanidin (CY) is one of the most abundant anthocyanidins found in red-purple diet sources such as grapes, blueberries and purple corns. CY has been proven to exhibit a wide range of biological functions including antioxidant, antiviral, anticarcinogenic and anti-inflammatory properties. PURPOSE: This study investigated the anti-depressive activity of CY and its related mechanism. METHODS: In the behavioral tests, CY-related effects on depressive symptoms were evaluated. Then the changes in PI3K/AKT/FOXG1/FGF-2 signaling and adult neurogenesis including doublecortin (DCX+) cell number, dendritic length, secondary and third dendrites number in the hippocampus were investigated by Immunofluorescence and Western blot analyses. PI3K antagonist LY 294,002 was used to verify the unique impact of PI3K/AKT/FoxG1/FGF-2 signaling on CY-related antidepressant efficacy. RESULTS: CY grossly reversed CUMS-induced behavioral defects, The DCX+ cell number and protein levels increased in CUMS mice receiving CY administration. LY 294,002 successfully blocked CY-induced improvements in depressive behaviors, neurogenesis, and protein levels in CUMS mice. CONCLUSION: The findings demonstrated that CY was efficacious in alleviating depression-like symptoms, which was dependent on PI3K/AKT/FoxG1/FGF-2 signaling-modulated neurogenesis enhancement.
RESUMO
BACKGROUND: Euphorbia factor L2 has potent effects on ascites, hydropsy and cancers. PURPOSE: We investigated the pharmacological effects of Euphorbia factor L2 (EFL2) on hepatocellular carcinoma (HCC). METHODS: MTT assay was conducted to determine the proliferative activity of EFL2 on Hep G2 and SMMC-7721 cells. Wound-healing assay, colony formation assay, western blotting and quantitative PCR were carried out to examine the cell migration, p-AKT and p-STAT3 signaling. Moreover, we used human tumor xenograft BALB/c nude mice to detect the effect of EFL2 on HCC in vivo. RESULTS: EFL2 inhibited the proliferation of SMMC-7721 and Hep G2 cells in concentration- and time-dependent manners. EFL2 also suppressed the cell migration and colony formation of hepatocellular carcinoma cells. Using a transforming growth factor-ß (TGF-ß)-induced epithelial-mesenchymal transition (EMT) model, we provided evidences that EFL2 could also inhibit TGF-ß induced cell growth, vimentin, N-cadherin expressions, activation of p-AKT and p-STAT3, whereas up-regulate E-cadherin expression. Furthermore, EFL2 inhibited tumor growth and STAT3 phosphorylation in vivo. CONCLUSION: In conclusion, EFL2 has the potential to be explored as a candidate treatment agent for HCC by inhibiting cell growth and migration both in vitro and in vivo.

The dried ripe fruit of Gardenia jasminoides Ellis was usually applied as an herb medicine in Traditional Chinese Medicine. It was suggested that the Gardenia jasminoides oil extract (oil from Fructus Gardeniae [OFG]) might serve as a potential treatment for depression, whereas its pathogenesis still remained not fully understood. The present research was conducted to evaluate the anti-depressive effect of OFG in mice and explore its potential mechanism. The OFG and ketamine (KET) were intragastrically and intraperitoneally treated, respectively. Thereafter, the animals were subjected to the behavior tests. The expressions of protein kinase A (PKA), brain derived neurotrophic factor (BDNF), cAMP response element-binding protein (CREB) in hippocampus were detected by Western blot. The selective PKA inhibitor H-89 was also applied to confirm the mechanism. As a result, OFG and KET treatment improved the behavior performance. Furthermore, the administrations of OFG effectively enhanced the expressions of PKA, p-CREB, and BDNF. With the application of selective PKA inhibitor H-89, the ameliorated effects caused by OFG were blocked, but not by KET. In conclusion, the presented work indicated that OFG-exerted protective effect on depression through PKA-CREB-BDNF signaling.

Residual tumor resulting in tumor recurrence after various anticancer therapies is an unmet challenge in current clinical oncology. This study aimed to investigate the hypothesis that radioiodinated hypericin (131I-Hyp) may inhibit residual tumor recurrence after microwave ablation (MWA) on rat orthotopic liver allograft sarcoma models.Thirty Sprague-Dawley (SD) rats with hepatic tumors were divided into three groups: Group A received laparotomy MWA and sequential intravenous injection (i.v.) of 131I labelled hypericin (131I-Hyp) in a time interval of 24 h; Group B received only laparotomy MWA; Group C was a blank control. Tumor inhibitory effects were monitored with in vivo magnetic resonance imaging (MRI) and these findings were compared to histopathology data before (baseline, day 0) and 1, 4, and 8 days after MWA. In addition, biodistribution of 131I-Hyp was assessed with in vivo single-photon emission computed tomography-computed tomography (SPECT-CT) imaging, in vitro autoradiography, fluorescent microscopy, and gamma counting.A fast clearance of 131I-Hyp and increasing deposit in necrotic tumors appeared over time, with a significantly higher radioactivity than other organs (0.9169 ± 1.1138 % ID/g, P < 0.01) on day 9. Tumor growth was significantly slowed down in group A compared to group B and C according to MRI images and corresponding tumor doubling time (12.13 ± 1.99, 4.09 ± 0.97, 3.36 ± 0.72 days respectively). The crescent tagerability of 131I-Hyp to necrosis was visualized consistently by autoradiography and fluorescence microscopy.In conclusion, 131I-Hyp induced necrosis targeted radiotherapy improved therapeutic outcomes of MWA on rat orthotopic liver allograft sarcoma models.

Infestation, moldy and other phenomenon in the processing and storage of Chinese herbal medicines is a problem that faced in the production of Chinese traditional medicine. The low productivity of traditional processing methods can not guarantee the quality of Chinese herbal medicines. Sulfur fumigation is the first choice of grassroots to process the Chinese herbal medicine with its low cost and easy operation. Sulfur fumigation can solve some problems in the processing and storage of Chinese herbal medicines, but modern pharmacological studies show that long-term use of Chinese traditional medicine which is fumigated by sulfur can cause some serious harm to human liver, kidney and other organs. This paper conducts a review about the application history of sulfur fumigation, its influence to the quality of Chinese herbal medicines as well as domestic and foreign limits to sulfur quantity, and a brief introduction of the status of modern processing technologies in the processing of food and some Chinese herbal medicines, the problems ex- isting in the Chinese herbal medicines processing, which can provide a reference basis for the further research, development and application of investigating alternative technologies of sulfur fumigation.

Sulfur fumigation (SF) is a universal phenomenon in primary processing of Traditional Chinese Medicine (TCM) in modern times. In the process, fumigation, sulfur or both of them act on the TCMs. Some active components of TCMs change quantitatively or qualitatively during the processing. At the same time, the sulfur dioxide and heavy metal would remain and cause a serious influence on quality and future development of TCM. This article reviews the chemical compositions change after SF to study the change law and their influence on quality. This article provide references for SF in TCMs' processing for a better and safer quality.

BACKGROUND: Studies comparing the procedural and clinical outcomes of catheter ablation for atrial fibrillation (AF) guided by CartoMerge and that by Carto have achieved mixed results (Carto, Biosense Webster, Diamond Bar, CA, USA). We collected these studies and conducted a meta-analysis to determine whether CartoMerge results in better procedural and clinical outcomes. METHODS AND RESULTS: Three randomized controlled trials and two controlled observational studies were collected for analysis. The clinical and procedural outcomes of interest were AF recurrence after catheter ablation, major complications, procedure durations, and fluoroscopy time. Meta-analysis was performed using RevMan 5.0.18 software (The Cochrane Collaboration, Copenhagen, Denmark) and pooled estimates of effect were reported as risk ratios with 95% confidence intervals (CI). The overall results of this meta-analysis indicate that catheter ablation for AF guided by CartoMerge is insignificantly associated with a decreased risk of recurrences (RR = 0.76; 95% CI: 0.55-1.04; P = 0.09) and major complications (RR = 0.73; 95% CI: 0.37-1.45; P = 0.37) compared with that by Carto. CONCLUSION: The image integration using CartoMerge guiding catheter ablation for AF does not improve the main clinical outcomes significantly compared with that by Carto in centers with experienced operators.

AIM: To explore the effect of neferine on angiotensin II (Ang II)-induced vascular smooth muscle cell (VSMC) proliferation. METHODS: Human umbilical vein smooth muscle cells (HUVSMCs) were used. Cell proliferation was determined by using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and flow cytometry analysis. Heme oxygenase (HO)-1 protein expression was tested by Western blot analysis. Extracellular signal-regulated protein kinase 1/2 (ERK1/2) activation was determined by using immunoblotting. RESULTS: Pre-incubation of HUVSMCs with neferine (0.1, 0.5, 1.0, and 5.0 micromol/L) significantly inhibited Ang II-induced cell proliferation in a concentration-dependent manner and neferine 5.0 micromol/L increased HO-1 expression by 259% compared with control. The antiproliferative effect of neferine was significantly attenuated by coapplication of zinc protoporphyrin IX (ZnPP IX, an HO-1 inhibitor) with neferine. Ang II-enhanced ERK1/2 phosphorylation was markedly reversed by neferine. By inhibiting HO-1 activity with ZnPP IX, the inhibitive effect of neferine on ERK1/2 phosphorylation was significantly attenuated. Cobalt-protoporphyrin (CoPP), an HO-1 inducer, significantly decreased Ang II-induced ERK1/2 phosphorylation and inhibited Ang II-induced cell proliferation. The ERK1/2 pathway inhibitor PD98059 significantly blocked Ang II-enhanced ERK1/2 phosphorylation and inhibited cell proliferation. CONCLUSION: These findings suggest that neferine can inhibit Ang II-induced HUVSMC proliferation by upregulating HO-1, leading to the at least partial downregulation of ERK1/2 phosphorylation.
