Syndrome Differentiation-based Treatment of Diarrhea-predominant Irritable Bowel Syndrome with Chinese Medicine via 5-HT Signaling Pathway： A Review / 中国实验方剂学杂志

Diarrhea-predominant irritable bowel syndrome （IBS-D） is a chronic functional bowel disorder characterized by abdominal pain and diarrhea， with visceral hypersensitivity and abnormal gastrointestinal dynamics as the pathophysiological basis. The brain-gut interaction plays a role in pain-related functional gastrointestinal disorders， especially IBS-D. 5-Hydroxytryptamine （5-HT）， as an important brain-gut peptide regulating gastrointestinal function， affects brain activity， gastrointestinal motility， pain perception， mucosal inflammation， and immune response through brain-gut interaction and is associated with the occurrence and development of IBS-D. In recent years， traditional Chinese medicine （TCM） has shown great potential to mitigate gastrointestinal symptoms and improve the quality of life with its holistic view and treatment based on syndrome differentiation. Studies have shown that TCM treats IBS-D by regulating the 5-HT signaling pathway. With a focus on syndrome differentiation in TCM， this paper systematically describes the efficacy and mechanism of TCM in treating different TCM syndromes of IBS-D via the 5-HT signaling pathway， aiming to provide a scientific basis for TCM treatment of this disease.

Melatonin treatment maintains the quality of cherry tomato by regulating endogenous melatonin and ascorbate-glutathione cycle during room temperature.

Changes in quality attributes, ascorbate-glutathione (AsA-GSH) cycle, and melatonin (MLT) synthesis were evaluated in cherry tomato fruit treated with MLT solution at 0.1 mM during storage at room temperature for 16 days. According to the results, the MLT treatment was beneficial to maintaining fruit quality as indicated by the declines in weight loss, fruit decay, and titratable acid (TA), accompanied by the maintenance of fruit firmness, total soluble solids (TSS) as well as TSS/TA ratio. Also, the MLT treatment not only effectively inhibited oxidative damage via reducing relative electrolyte leakage and malondialdehyde content, but also improved antioxidant capacity via stimulating AsA-GSH cycle. Moreover, the MLT treatment promoted endogenous MLT synthesis by upregulating the expressions of biosynthetic genes consisting of SlTDC, SlT5H, SlSNAT, and SlASMLT. Thus, our results suggested that the MLT treatment might be involved in maintaining quality in cherry tomato fruit during room temperature by promoting antioxidant capacity and enhancing endogenous MLT. PRACTICAL APPLICATIONS: As a typical climacteric fruit, cherry tomato fruit ripen rapidly and are easily infected by various pathogenic fungi during storage under ambient conditions, which leads to short storage life and a decrease in economic value. The results showed that the application of MLT maintained cherry tomato quality via improving antioxidant capacities and enhancing endogenous MLT. Therefore, MLT treatment could become a promising postharvest strategy for quality maintenance in cherry tomatoes during room storage.

Inhibitory effect of tanshinone IIA, resveratrol and silibinin on enterovirus 68 production through inhibiting ATM and DNA-PK pathway.

BACKGROUND: Human enterovirus 68 (EV68) is a primary etiological agent for respiratory illnesses, while no effective drug has yet used in clinics largely because the pathogenesis of EV68 is not clear. DNA damage response (DDR) responds to cellular DNA breaks and is also involved in viral replication. Three DDR pathways includes ataxia telangiectasia mutated (ATM), ATM and Rad3-related (ATR), and DNA-dependent protein kinase (DNA-PK). Natural products proved to be an excellent source for the discovery and isolation of novel antivirals. Among them, tanshinone IIA, resveratrol, silibinin, rutin and quercetin are reported to target DDR, therefore their roles in anti-EV68 are investigated in this study. PURPOSE: This study investigated the anti-EV68 ability of various natural compounds related to DDR. STUDY DESIGN AND METHODS: The methods include cell counting, flow cytometry, western blot, Immunofluorescence staining, comet assays, quantitative real-time RT PCR and short interfering RNAs (siRNAs) for analysis of cell number, cell cycle, protein expression, protein location, DNA damage, mRNA level and knock down target gene, respectively. RESULTS: EV68 infection induced DDR. Down-regulation or inhibition of ATM or DNA-PK lowered DDR in EV68-infected cells and mitigated viral protein expression, however, down-regulation or inhibition of ATR unexpectedly up-regulated DDR, and promoted viral protein expression. Meanwhile tanshinone IIA, resveratrol, and silibinin inhibited ATM and/or DNA-PK activation and decreased viral proliferation, while rutin and quercetin inhibited ATR activation and promoted viral production. The role of them in ATM, DNA-PK and ATR activation was consistent with previous reports. CONCLUSION: Tanshinone IIA, resveratrol and silibinin inhibited EV68 proliferation through inhibiting ATM and/or DNA-PK activation, and they were effective anti-EV68 candidates.

Melatonin treatment delays ripening in mangoes associated with maintaining the membrane integrity of fruit exocarp during postharvest.

The effects of exogenous melatonin on postharvest ripening of mango (Mangifera indica L. cv. Keitt) were investigated after the fruit were dipped in 0 (as the control), 100, or 200 µM melatonin solution for 30 min, and then stored at room temperature (25 ± 1 °C). The results showed that melatonin treatments could delay the ripening process as indicated by inhibition to softening, respiration, color change and chlorophyll degradation in fruit during storage. Notably, 200 µM melatonin treatment delayed the degradation of phosphatidylglycerol (PG) and phosphatidylinositol (PI), and the accumulation of phosphatidylserine (PS) and phosphatidic acid (PA) in membrane phospholipids, inhibited the decrease in unsaturated fatty acids (IUFA) index and also decreased the contents of H2O2 and malondialdehyde (MDA) in the exocarp of the fruit, which might collectively contribute to the integrity of the membrane associated with the delay in the ripening process of mango fruit during postharvest.

Mechanism of Shaofu Zhuyu Decoction in treatment of EMT induced dysmenorrhea based on network pharmacology and molecular docking / 中国中药杂志

Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform(TCMSP) and Bioinformatics Analysis Tool for Molecular Mechanism of Traditional Chinese Medicine(BATMAN-TCM) were searched for the effective components and targets of Shaofu Zhuyu Decoction. The relevant targets for endometriosis(EMT) and dysmenorrhea were retrieved from the Comparative Toxicogenomics Database(CTD), Therapeutic Target Database(TTD), GeneCards, and DisGeNET with the terms of "endometriosis" and "dysmenorrhea". Cytoscape 3.8.0 was employed to construct the drug-active component-therapeutic target network. A protein-protein interaction(PPI) network was established by STRING 11.0. Analyze Network, the plug-in in the Cytoscape 3.8.0, was used to calculate the topological parameters of the nodes and screen out the critical proteins in the network. The potential therapeutic targets were imported into RStudio and subjected to Gene Ontology(GO) and Kyoto Encyclopedia of Genes and Genomes(KEGG) enrichment analyses with clusterProfiler package. Finally, the AutoDock Vina(Vina) platform was used for molecular docking to predict the binding degree of the main active components of Shaofu Zhuyu Decoction to key targets. As revealed by the screening results, 136 active components and 380 targets of Shaofu Zhuyu Decoction were obtained. Additionally, there were 1 627 targets related to EMT and 142 targets related to dysmenorrhea with 107 common targets, and 42 potential therapeutic targets of Shaofu Zhuyu Decoction for the treatment of EMT-induced dysmenorrhea. The targets such as interleukin 6(IL6) and prostaglandi-nendoperoxide synthase-2(PTGS2) were pivotal in the biological network of Shaofu Zhuyu Decoction intervention in EMT-induced dysmenorrhea, which involved multiple signaling pathways, including inflammation, hormones, and those promoted cell proliferation [e.g., mitogen-activated protein kinase(MAPK) and phosphatidylinositol-3 kinase(PI3 K)-protein kinase B(AKT)]. The results of molecular docking showed that the active components of Shaofu Zhuyu Decoction had good binding capacities to key targets such as IL6 and PTGS2. The findings of this study demonstrated that Shaofu Zhuyu Decoction could treat EMT-induced dysmenorrhea through multiple targets and multiple pathways, which could provide new ideas for investigating the underlying mechanism of Shaofu Zhuyu Decoction in the treatment of EMT-induced dysmenorrhea.

Clinical features and long-term follow-ups of juxtapapillary retinal capillary hemangioma / 中华眼底病杂志

Objective:To evaluate the clinical features and follow-up effect of treatment for retinal capillary hemangioma (RCH) of myopic disc.Methods:Retrospective case series studies. A total of 14 patients (15 eyes) diagnosed with juxtapapillary RCH (JRCH) at Peking Union Medical College Hospital and followed up for more than 12 months from January 2007 to December 2019 were included. Among these patients, there were 7 males (7 eyes) and 7 females (8 eyes) with the average age of 29.8±12.7 years. There were 6 isolated JRCH cases, all of which were monocular patients, including 1 case with a single peripheral RCH; 8 cases with von Hippel-Lindau disease, including 5 cases of binocular RCH. Out of 15 eyes, 6 eyes were merged with peripheral RCH. Three eyes were simply observed, and 12 eyes were treated with photodynamic therapy (PDT) alone or PDT combined with other treatments. The average follow-up time was 55.2 months. Its clinical characteristics and long-term treatment effects were analyzed.Results:At the first visit, among the 15 eyes, 3 eyes had visual acuity <0.1, 5 eyes were 0.1-0.4, and 7 eyes were> 0.5. The endogenous and fixed exogenous JRCH were 12 (80%, 12/15) and 3 (20%, 3/15) eyes, respectively. The size of the tumor was 1/4 to 4 optic disc diameters (DD); the combined macular edema, epiretinal membrane, and macular hole were 11, 5, and 1 eyes, respectively. There were 3 eyes with tumor diameter less than 1 DD. The visual acuity at the first diagnosis was 0.6-1.0, and no treatment was given. The follow-up time was 12 months in 2 eyes and 120 months in 1 eye. At the last follow-up, his vision remained stable and the tumor did not enlarge. Six eyes with tumor diameter ranging from 1.0 to 2.5 DD, visual acuity was 0.06 to 0.6 at first diagnosis, accompanied by retinal exudation. 5 eyes were treated with PDT alone, and 1 eye was treated with PDT combined with anti-vascular endothelial growth factor drugs. The follow-up time was 12 to 84 months. At the last follow-up, the visual acuity improved or stabilized in 5 eyes and decreased in 1 eye. There were 6 eyes with peripheral RCH, including 4 eyes with retinal detachment, 2 eyes with epiretinal membrane, and 1 eye with vitreous hemorrhage. The visual acuity at the first visit was 0.02-0.6. All patients were treated with PDT combined with transpupillary thermotherapy, extrascleral drainage, and vitrectomy. The follow-up time was 12 to 132 months. At the last follow-up, all eyesight decreased.Conclusions:Visual decrease cause by JRCH often occurs at young adults. Bilateral JRCH are more common in patients with von Hippel-Lindau's disease. The tumor can cause retinal exudation, macular edema, epiretinal membrane and macular hole, resulting in gradual vision loss. PDT and/or combined anti-vascular endothelial growth factor drugs for medium sized JRCH with retinal exudation can maintain long-term vision stability. Patients with large JRCH or severe complications such as retinal detachment tend to have poor prognosis.

Mechanism of Danggui Sini Decoction in treatment of primary dysmenorrhea based on network pharmacology and molecular docking / 中国中药杂志

Network pharmacology, molecular docking and in vivo experiments were used to explore the pharmacodynamic basis and potential mechanism of Danggui Sini Decoction in the treatment of primary dysmenorrhea(PD). The chemical constituents of Danggui(Angelicae Sinensis Radix), Guizhi(Cinnamomi Ramulus), Tongcao(Tetrapanacis Medulla), Baishao(Paeoniae Radix Alba), Xixin(Asari Radix et Rhizoma), Gancao(Glycyrrhizae Radix et Rhizoma), and Dazao(Jujubae Fructus) from Danggui Sini Decoction were retrieved through TCMSP(Traditional Chinese Medicine Systems Pharmacology Database), and the action targets of Danggui Sini Decoction were collected through DrugBank. "Primary dysmenorrhea" and "dysmenorrhea" were used as the key words to search the corresponding targets in the GeneCards, OMIM and TTD databases, and then the intersection targets of Danggui Sini Decoction and the primary dysmenorrhea targets were taken for reverse screening to obtain the corresponding active ingredients. Cytoscape 3.6.1 software was used to construct a traditional Chinese medicine-compound-target-disease network; STRING database was used to build a protein-protein interaction(PPI) network; Gene ontology(GO) function enrichment analysis and Kyoto encyclopedia of genes and genomes(KEGG) pathway enrichment analysis were conducted by using DAVID database. The action mechanism of the intersection targets were then predicted, and a histogram chart and bubble chart were drawn for visualization. Then the top five targets in the PPI network were used for docking with the most compounds. In animal experiments, Sprague Dawley(SD) female rats were used to establish a primary dysmenorrhea model by intraperitoneal injection of diethylstilbestrol once a day. A total of 60 SD female rats were randomly divided into 6 groups, namely control group, model group, Danggui Sini Decoction low(1.5 g·kg~(-1)), medium(3.0 g·kg~(-1)), high(6.0 g·kg~(-1)) dose groups, and ibuprofen(20 mg·kg~(-1)) positive control group, with 10 rats in each group. From day 4, except for the control group, rats in the other groups were given intragastric administration of corresponding drugs, and the control group received intragastric administration of normal saline for 7 consecutive days. The number of writhing before and after the administration, the ute-rine contraction inhibition rate and the uterine index after administration were observed, and ELISA assay was used to detect the levels of prostaglandin-endoperoxide synthase 2(PTGS2) and vascular endothelial growth factor A(VEGFA) in the tissues of each group as well as the levels of serum inflammatory factors interleukin 1(IL-1), interleukin 6(IL-6), and tumor necrosis factor-alpha(TNF-α). According to network analysis, 7 Chinese medicines contained 114 active ingredients, 149 targets, and 30 common target genes with PD were obtained. The key targets included VEGFA, IL6, PTGS2, TNF, etc.; GO function enrichment analysis showed a total of 399 terms(P<0.05) were obtained, 353 of which were biological process(BP) terms, 21 were cell composition(CC) terms, and 25 were molecular function(MF) terms. In KEGG pathway enrichment analysis, 14 signaling pathways were obtained, 3 of which were related to inflammation, namely arachidonic acid metabolism, MAPK signaling pathway and NOD-like receptor signaling pathway. The compounds in Danggui Sini Decoction can play a therapeutic role in the treatment of PD by acting on VEGFA, IL-6, PTGS2, TNF and other targets to regulate arachidonic acid and inflammatory signaling pathways.

Effect of benzothiadiazole treatment on quality and anthocyanin biosynthesis in plum fruit during storage at ambient temperature.

BACKGROUND: Plums tend to experience a reduction in fruit quality due to ripening and they deteriorate quickly during storage at room temperature. Benzothiadiazole (BTH) is a plant elicitor capable of inducing disease resistance in many crops. In this study, the effect of BTH treatment on fruit ripening, fruit quality, and anthocyanin biosynthesis in 'Taoxingli' plum was investigated. RESULTS: The results showed that BTH treatment could accelerate fruit ripening without affecting the incidence of fruit decay or the shelf life. Benzothiadiazole treatment improved the quality and consumer acceptability of 'Taoxingli' plums during storage by increasing the sweetness, red color formation, and the concentration of healthy antioxidant compounds. The BTH treatment could also effectively promote the biosynthesis of anthocyanin by enhancing the enzyme activities of phenylalanine ammonia-lyase (PAL), dihydroflavonol 4-reductase (DFR), anthocyanidin synthase (ANS), and uridine diphosphate flavonoid 3-O-glucosyltransferase (UFGT) and up-regulating the gene expressions of PsPAL, PsCHI, PsDFR, PsANS, and PsUFGT during storage. CONCLUSION: Benzothiadiazole treatment could be a potential postharvest technology for improving fruit quality and consumer acceptability in harvested plum fruit. © 2020 Society of Chemical Industry.

1-Methylcyclopropene treatment controls ethanol accumulation associated with regulation of mitochondrial energy metabolism in kiwifruit (Actinidia deliciosa) cv. "Bruno" during storage at room temperature.

In this paper, the effects of 1-methylcyclopropene (1-MCP) treatment on the ethanol accumulation and mitochondrial energy metabolism in kiwifruit (Actinidia deliciosa) cv. "Bruno" were investigated during storage at room temperature (24 ± 1°C). The results showed that 1-MCP treatment significantly reduced the ethanol accumulation, maintained higher levels of adenosine triphosphate (ATP) content and energy charge (EC), enhanced enzymes activities involved in mitochondrial energy metabolism, such as succinic dehydrogenase, cytochrome C oxidase, H+ -adenosine triphosphatase (H+ -ATPase), and Ca2+ -adenosine triphosphatase (Ca2+ -ATPase), and regulated the NADH/NAD+ ratio, and pyruvate to tricarboxylic acid cycle (TCA) by suppressing the glutamate-pyruvate transaminase and promoting the pyruvate dehydrogenase activity, and decarboxylation of citric acid in harvested kiwifruit. These shifts in mitochondrial energy metabolism and oxidative phosphorylation correlated the higher ATP yield and an elevated EC with lower ethanol accumulation (13.71% of those in the control fruit) under 1-MCP treatment, and reduced the susceptibility of ethanol related off-flavor disorder in kiwifruit during storage. PRACTICAL APPLICATIONS: A kiwifruit (Actinidia deliciosa) cv. "Bruno," a major cultivated kiwifruit in China, is prone to accumulate ethanol sharply after respiratory climacteric during storage. Ethanol has been accounted as a vital aroma volatile metabolite in various fruits. However, over accumulation of ethanol often leads to the development of alcohol off-flavor disorder, particularly in typical climacteric fruit such as kiwifruit. This work was aimed to maintain the flavor quality of kiwifruit cv. "Bruno" via improving the mitochondrial energy metabolism and functional TCA cycle, and limiting the ethanol accumulation under 1-MCP treatment. Thus, 1-MCP treatment could be beneficial to prevent the occurrence of alcohol off-flavor disorder along with sustainment of the flavor quality of kiwifruit cv. "Bruno" during storage at room temperature.

Dendrobium officinale Kimura et Migo and American ginseng mixture: A Chinese herbal formulation for gut microbiota modulation / 中国天然药物

Dendrobium officinale Kimura et Migo (D. officinale) is a famous traditional Chinese medicine (TCM). A mixture of D. officinale and American ginseng has been shown to enhance cell-mediated immunity, humoral immunity, and monocyte/macrophage functions in mice. Here, the effects of a D. officinale and American ginseng mixture on the structure of gut microbial community in dogs were examined using high-throughput 16S rRNA gene amplicon sequencing. The data revealed that while the mixture did not change the diversity of gut microbial community significantly, differences among individuals were significantly reduced. Furthermore, the mixture-responsive operational taxonomic units (OTUs) exhibited a phase-dependent expression pattern. Fifty-five OTUs were found to exhibit a mixture-induced expression pattern, among which one third were short-chain fatty acid (SCFA)-producing genera and the others were probiotic genera included Lactobacillus spp., Sutterella, Alistipes, Anaerovorax, Bilophila, Coprococcus, Gordonibacter, Oscillibacter, among others. By contrast, 36% of the OTUs exhibiting a mixture-repressed expression pattern were disease-associated microorganisms, and six genera, namely Actinomyces, Escherichia/Shigella, Fusobacterium, Slackia, Streptococcus and Solobacterium, were associated with cancer. In addition, five genera were closely associated with diabetes, namely Collinsella, Rothia, Howardella, Slackia and Intestinibacter. Our results indicate that this D. officinale and American ginseng mixture may be used as a prebiotic agent to enhance SCFA-producing genera and prevent gut dysbiosis.

Fecal medicines used in traditional medical system of China: a systematic review of their names, original species, traditional uses, and modern investigations.

In China, the medical use of fecal matter (fresh fecal suspension or dry feces) can be dated back to the fourth century, approximately 1700 years ago. In long-term clinical practice, Chinese doctors have accumulated unique and invaluable medical experience in the use of fecal materials. In view of their good curative effect and medicinal potential, fecal medicines should be paid much attention. This study aimed to provide the first comprehensive data compilation of fecal medicines used in various Chinese traditional medical systems by bibliographic investigation of 31 medicine monographs and standards. A total of 54 fecal medicines were found to be used in 14 traditional Chinese medical systems. Their names, original species, medicinal forms, and traditional uses were described in detail. These fecal medicines were commonly used to treat gastrointestinal, nervous system, skin, and gynecological diseases. Commonly used fecal medicines include Wu-Ling-Zhi, Jiu-Fen and Hei-Bing-Pian. The information summarized in this study can provide a good reference for the development and utilization of fecal medicines. Further studies are necessary to prove their medicinal value, identify their active ingredients, and elucidate their mechanisms of action so that more people can accept these special medicines.

Effect of ingredients from Chinese herbs on enterovirus D68 production.

Human enterovirus 68 (EVD68) is a primary causative agent for respiratory illness worldwide. Until now, there has been no available medication for treating EVD68-related diseases. Rheum emodin, artemisinin, astragaloside, pseudolaric acid B, oridonin, and erianin are natural extracts from Chinese herbs that have traditionally been used for the treatment and prevention of epidemic diseases. Our results showed that pseudolaric acid B protected cells from EVD68-induced cytopathic effects and decreased viral production. However, the same effects were not observed with rheum emodin, astragaloside, or artemisinin. Pseudolaric acid B inhibited EVD68 production by manipulating the host cell cycle in G2/M phase. Further, either oridonin or erianin related G2/M arrest also inhibited viral production. Due to inducing G2/M phase arrest, pseudolaric acid B, oridonin, and erianin might be good candidates for inhibiting EVD68 production, and Chinese herbs with natural compounds inducing G2/M arrest should be considered for the treatment of EVD68-related diseases.

Administration of Electroacupuncture and Da-Cheng-Qi Decoction Has a Synergetic Effect in Relieving Injury of Pancreas, Lung and Large Intestine and Inflammatory Reactions in Rats with Acute Pancreatitis / 针刺研究

OBJECTIVE: To explore the effectiveness of electroacupuncture (EA) stimulation of Shu-and Mu-points of Lung and Large Intestine Meridians combined with administration of Da-Cheng-Qi Decoction (DCQD) in the treatment of inflammatory injury in rats with acute pancreatitis, so as to reveal their synergetic anti-inflammatory effect. METHODS: Forty male SD rats were randomly divided into five groups: normal control, model, DCQD, EA, EA+DCQD, with 8 rats in each group. All the rats except those in the normal group received a retrograde biliopancreatic duct injection of sodium Taurocholate (3.0%, 0.1 mL/100 g) to induce an acute pancreatitis model. Twenty-four hours after modeling, EA (4 Hz/50 Hz) was applied to bilateral Shu-points "Feishu" (BL 13) and "Dachangshu" (BL 25), and Mu-points "Zhongfu" (LU 1) and "Tianshu" (ST 25) for 20 min, once every 7 h, 3 times in total. Rats of the DCQD and EA+DCQD groups were given intra-gastric gavage of DCQD (1 mL/100 g) 24 h after modeling, and those of the other 3 groups were given intra-gastric gavage of same dosage of normal saline. The histopathological changes of the pancreas, lung and large intestine tissues were observed after H. E. staining and scored according to Schmidt's and colleagues' methods (the severity of edema, inflammation, hemorrhage, necrosis). The concentrations of interleukin-6 (IL-6) and IL-10 in the serum, and those of myeloperoxidase (MPO) and malonaldehyde (MDA) in the lung and large intestine tissues were detected by using double-antibody sandwich ELISA. RESULTS: After modeling, the histopathological scores of pancreas, lung and large intestine tissues, the concentrations of MPO and MDA in lung and large intestine, and the levels of IL-6 and IL-10 in serum were significantly increased in the model group compared with the normal control group (P0.05). CONCLUSION: EA and DCQD can relieve the inflammatory injury of the pancreas, lung and large intestine tissues in rats with acute pancreatitis, and EA combined with DCQD has a better synergetic effect in reducing oxidative stress level and inflammatory reaction.

Effects of Electroacupuncture on Morphology Repairment and Basic Fibroblast Growth Factor/Extracellular Signal-regulated Kinase Signal Pathway of Rabbits with Acute Lumbar Muscle Contusion / 中国康复理论与实践

@#Objective To observe the effect of electroacupuncture on basic fibroblast growth factor (bFGF), Desmin and extracellular signal-regulated kinase (ERK1/2) expression of rabbits with acute lumbar muscle contusion, and discuss the possible mechanism of muscle tissue regeneration and repair. Methods 40 male New Zealand rabbits were randomly divided into blank group (BG, n=10), model group (MG, n=10), Weizhong (BL40) electroacupuncture group (WG, n=10) and local electroacupuncture group (LG, n=10). Lumbar muscle injury was established with blunt trauma, and the rabbits were assessed with Appearance Score. The WG and LG accepted electroacupuncture for 2 weeks after modeling. The lumbar muscle of each animal was stained with HE to observe pathological changes, and immunohistochemical staining was used to observe bFGF expression, and Western blotting was used to detect the expression of Desmin and ERK1/2 protein.Results Appearance Score was more in the MG, WG and LG than in the BG (P<0.01). Histological score ranked from more to less as MG,LG, WG and BG (P<0.05). The expression of bFGF ranked as LG, WG, MG and BG (P<0.01), Desmin ranked as WG=LG and BG=MG (P<0.05), ERK1/2 as LG=WG, MG and BG (P<0.05). Conclusion Electroacupuncture could promote the regeneration and repair of tissue after acute lumbar muscle contusion, which may be related to the up-regulation of bFGF/ERK signaling pathway.

AIM@#To evaluate the anti-HIV activity and mechanism of action of wikstroelide M, a daphnane diterpene from Daphne acutiloba Rehder (Thymelaeaceae).@*METHODS@#The anti-HIV activities of wikstroelide M against different HIV strains were evaluated by cytopathic effect assay and p24 quantification assay with ELISA. The inhibitory effect of wikstroelide M on HIV reverse transcription was analyzed by real-time PCR and ELISA. The effect of wikstroelide M on HIV-1 integrase nuclear translocation was observed with a cell-based imaging assay. The effect of wikstroelide M on LEDGF/p75-IN interaction was assayed by molecular docking.@*RESULTS@#Wikstroelide M potently inhibited different HIV-1 strains, including HIV-1IIIB, HIV-1A17, and HIV-19495, induced a cytopathic effect, with EC50 values ranging from 3.81 to 15.65 ng·mL⁻¹. Wikstroelide M also had high inhibitory activities against HIV-2ROD and HIV-2CBL-20-induced cytopathic effects with EC50 values of 18.88 and 31.90 ng·mL⁻¹. The inhibitory activities of wikstroelide M on the three HIV-1 strains were further confirmed by p24 quantification assay, with EC50 values ranging from 15.16 to 35.57 ng·mL⁻¹. Wikstroelide M also potently inhibited HIV-1IIIB induced cytolysis in MT-4 cells, with an EC50 value of 9.60 ng·mL⁻¹. The mechanistic assay showed that wikstroelide M targeted HIV-1 reverse transcriptase and nuclear translocation of integrase through disrupting the interaction between integrase and LEDGF/p75.@*CONCLUSION@#Wikstroelide M may be a potent HIV-1 and HIV-2 inhibitor, the mechanisms of action may include inhibition of reverse trascriptase activity and inhibition of integrase nuclear translocation through disrupting the interaction between integrase and LEDGF/p75.

Efficacy of yindan xinnaotong soft capsule on cerebral infarction reconvalescents of static blood blocking collaterals syndrome: a randomized controlled study / 中国中西医结合杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of Yindan Xinnaotong Soft Capsule (YXSC) on cerebral infarction (CI) reconvalescents of static blood blocking collaterals syndrome (SBBCS).</p><p><b>METHODS</b>Totally 118 CI reconvalescents of SBBCS were randomly assigned to the test group (treated by YXSC) and the control group [treated by Naoxintong Capsule (NC)], 59 in each group. The therapeutic course for all was 12 weeks. Changes of National Institute of Health Stroke Scale (NIHSS), Barthel Index (BI), modified Rankin Scale (mRS), Chinese medical syndrome scores, and serum lipid indices were observed in the two groups.</p><p><b>RESULTS</b>Compared with the control group, the patient proportion of improving activities of daily life by more than or equal to 75 score was elevated (80.7% vs 62.5%; P < 0.05). Compared with before treatment in the same group, the NIHSS score decreased at post-treatment 4, 8, and 12 weeks in the two groups (P < 0.05). The patient proportion of dropped NIHSS score by more than or equal to 5 score was lowered (80.7% vs 57.14%), and the total effective rate of improving Chinese medical syndromes was superior in the test group after 12-week treatment (89.47% vs 71.43%, all P < 0.05). After 12-week treatment there was no statistical difference in the patient proportion of lowering mRS lower than or equal to 2 or blood lipids between the two groups (P > 0.05).</p><p><b>CONCLUSION</b>YXSC showed certain effect in improving activities of daily life, attenuating the neurological impairment, and elevating the total effective rate of improving Chinese medical syndromes in CI patients in the recovery stage.</p>
