Inhibitory interaction of flavonoids with organic anion transporter 3 and their structure-activity relationships for predicting nephroprotective effects.

The organic anion transporter 3 (OAT3), an important renal uptake transporter, is associated with drug-induced acute kidney injury (AKI). Screening and identifying potent OAT3 inhibitors with little toxicity in natural products, especially flavonoids, in reducing OAT3-mediated AKI is of great value. The five strongest OAT3 inhibitors from the 97 flavonoids markedly decreased aristolochic acid I-induced cytotoxicity and alleviated methotrexate-induced nephrotoxicity. The pharmacophore model clarified hydrogen bond acceptors and hydrophobic groups are the critical pharmacophores. These findings would provide valuable information in predicting the potential risks of flavonoid-containing food/herb-drug interactions and optimizing flavonoid structure to alleviate OAT3-related AKI.

Traditional Chinese medicine formula 01 for nasopharyngeal carcinoma (NPC01) for head & neck cancer and health-related quality of life: a retrospective study.

BACKGROUND: The traditional Chinese medicine (TCM) formula 01 for nasopharyngeal carcinoma (NPC01) is used in the management of head and neck cancers (HNCs), but whether NPC01 has an impact on the HR-QOL of patients with HNCs is unknown. METHODS: This was a retrospective study of patients with HNCs who were treated between January 2019 and January 2020 at the Head & Neck Cancer Center of Tianjin Medical University Cancer Institute & Hospital. The patients were grouped according to whether they received NPC01 or not (controls). All patients routinely completed the EORTC QLQ-C30 and QLQ-H&N35 modules before and after 3 months of systemic treatment. Health economics were collected. RESULTS: The patients who received NPC01 were older than the controls (48.6 ± 11.4 vs. 43.4 ± 8.8 years, P = 0.004). All other characteristics were comparable between the two groups (all P > 0.05). In EORTC QLQ-C30, physical functioning (P = 0.03), fatigue (P = 0.04), pain (P = 0.02), appetite loss (P = 0.02), and constipation (P = 0.01) scores were improved more in the NPC01 group than in controls. In EORTC H&N35, the scores for pain (P = 0.02), swallowing (P = 0.01), and dry mouth (P = 0.02) were better in the NPC01 group than in controls. The NPC01 cost was 38.94 RMB/patient compared with 12.81 RMB/patient for regular follow-up, but considering insurance coverage, the financial burden was not higher. CONCLUSIONS: The results suggest that NPC01 improves HNCs-related symptoms and HR-QOL.

Grab regulates transferrin receptor recycling and iron uptake in developing erythroblasts.

Developing erythroblasts acquire massive amounts of iron through the transferrin (Tf) cycle, which involves endocytosis, sorting, and recycling of the Tf-Tf receptor (Tfrc) complex. Previous studies on the hemoglobin-deficit (hbd) mouse have shown that the exocyst complex is indispensable for the Tfrc recycling; however, the precise mechanism underlying the efficient exocytosis and recycling of Tfrc in erythroblasts remains unclear. Here, we identify the guanine nucleotide exchange factor Grab as a critical regulator of the Tf cycle and iron metabolism during erythropoiesis. Grab is highly expressed in differentiating erythroblasts. Loss of Grab diminishes the Tfrc recycling and iron uptake, leading to hemoglobinization defects in mouse primary erythroblasts, mammalian erythroleukemia cells, and zebrafish embryos. These defects can be alleviated by supplementing iron together with hinokitiol, a small-molecule natural compound that can mediate iron transport independent of the Tf cycle. Mechanistically, Grab regulates the exocytosis of Tfrc-associated vesicles by activating the GTPase Rab8, which subsequently promotes the recruitment of the exocyst complex and vesicle exocytosis. Our results reveal a critical role for Grab in regulating the Tf cycle and provide new insights into iron homeostasis and erythropoiesis.

Two high hierarchical regulators, PuMYB40 and PuWRKY75, control the low phosphorus driven adventitious root formation in Populus ussuriensis.

Adventitious rooting is an essential biological process in the vegetative propagation of economically important horticultural and forest tree species. It enables utilization of the elite genotypes in breeding programmes and production. Promotion of adventitious root (AR) formation has been associated with starvation of inorganic phosphate and some factors involved in low phosphorus (LP) signalling. However, the regulatory mechanism underlying LP-mediated AR formation remains largely elusive. We established an efficient experimental system that guaranteed AR formation through short-term LP treatment in Populus ussuriensis. We then generated a time-course RNA-seq data set to recognize key regulatory genes and regulatory cascades positively regulating AR formation through data analysis and gene network construction, which were followed by experimental validation and characterization. We constructed a multilayered hierarchical gene regulatory network, from which PuMYB40, a typical R2R3-type MYB transcription factor (TF), and its interactive partner, PuWRKY75, as well as their direct targets, PuLRP1 and PuERF003, were identified to function upstream of the known adventitious rooting genes. These regulatory genes were functionally characterized and proved their roles in promoting AR formation in P. ussuriensis. In conclusion, our study unveiled a new hierarchical regulatory network that promoted AR formation in P. ussuriensis, which was activated by short-term LP stimulus and primarily governed by PuMYB40 and PuWRKY75.

Mechanism of Prunellae Spica Against Breast Diseases： A Review / 中国实验方剂学杂志

Prunellae Spica is the dry ear of the labiaceae plant Prunella vulgaris， which is a traditional medicine and food plant with many functions. Prunellae Spica can clear liver-fire， improve eyesight， disperse knot detumescence. It owns hot and bitter flavors and cold property. It goes to the liver， gallbladder meridian， and is a kind of commonly-used antifebric. Prunellae Spica has been used in the treatment of mammary gland diseases since ancient times.The mammary abscess， mammary nodules， mammary carcinoma of traditional Chinese medicine all belong to breast disease， and the liver meridian is most closely related to these diseases. With the development of social life， breast disease has gradually become the most primary health problem for women. Modern pharmacological studies show that Prunellae Spica contains terpenoids， phenolic acids， flavonoids and other biological active components， which have anti-inflammatory， antibacterial， hormone regulation， anti-tumor and other effects. Prunellae Spica inhibits the p38 mitogen-activated protein kinase （p38 MAPK）/nuclear factor kappa-B （NF-κB） pathway to play an anti-mastitis role， interferes with the effects of estrogen receptors or regulates lipid levels to treat breast hyperplasia， and treats breast cancer through promoting the apoptosis of breast cancer cells， inhibiting the migration of breast cancer cells， regulating the division of breast cancer cells and other ways. While referring to the relevant literature， it was found that Prunellae Spica often exerted pharmacological effects through multi-channels and multi-target regulation， but most of the studies did not specify the specific target of its effect， which needs further study. In this review， the effects and mechanisms of Prunellae Spica in the treatment of various breast diseases were summarized， so as to provide a reference for further research on the wider clinical therapeutic effects of Prunella subtilis and its therapeutic effects on breast diseases.

Enhanced Bioreduction of Radionuclides by Driving Microbial Extracellular Electron Pumping with an Engineered CRISPR Platform.

Dissimilatory metal-reducing bacteria (DMRB) with extracellular electron transfer (EET) capability show great potential in bioremediating the subsurface environments contaminated by uranium through bioreduction and precipitation of hexavalent uranium [U(VI)]. However, the low EET efficiency of DMRB remains a bottleneck for their applications. Herein, we develop an engineered CRISPR platform to drive the extracellular electron pumping of Shewanella oneidensis, a representative DMRB species widely present in aquatic environments. The CRISPR platform allows for highly efficient and multiplex genome editing and rapid platform elimination post-editing in S. oneidensis. Enabled by such a platform, a genomic promoter engineering strategy (GPS) for genome-widely engineering the EET-encoding gene network was established. The production of electron conductive Mtr complex, synthesis of electron shuttle flavin, and generation of NADH as intracellular electron carrier are globally optimized and promoted, leading to a significantly enhanced EET ability. Applied to U(VI) bioreduction, the edited strains achieve up to 3.62-fold higher reduction capacity over the control. Our work endows DMRB with an enhanced ability to remediate the radionuclides-contaminated environments and provides a gene editing approach to handle the growing environmental challenges of radionuclide contaminations.

Objective: To observe the clinical efficacy of ginger-partitioned moxibustion plus pediatric massage (tuina) in treating infantile diarrhea due to spleen deficiency. Methods: Ninety infants were randomly divided into a massage plus moxibustion group, a massage group and a drug group by the random number table method, with 30 cases in each group. The intervention was conducted for two consecutive courses. The infants in the massage plus moxibustion group were treated with pediatric massage and ginger-partitioned moxibustion at Shenque (CV 8). The infants in the massage group were treated with pediatric massage alone, while those in the drug group were treated with smecta. The primary and secondary symptom scales were assessed before and after treatment and at the follow-ups, and the total effective rate was evaluated after treatment. Results: The total effective rate in the massage plus moxibustion group was significantly different from that in the massage group and drug group (both P<0.05). After treatment, the scores of primary and secondary symptoms decreased in all three groups, with statistically significant intra-group differences (all P<0.05); the scores of primary symptoms were significantly different between the massage plus moxibustion group and the drug group (P<0.05); the scores of secondary symptoms in the massage plus moxibustion group and the massage group were significantly different from that in the drug group (both P<0.05). The differences in the time to recover normal bowel movement frequency among the three groups were not statistically significant (P>0.05). Conclusion: Ginger-partitioned moxibustion plus pediatric massage compared with pediatric massage or smecta monotherapy shows superior clinical efficacy in treating infantile diarrhea due to spleen deficiency, and has the advantages of appetite improvement, physique strengthening and short course.

EEG-controlled functional electrical stimulation rehabilitation for chronic stroke: system design and clinical application / 医学前沿

Stroke is one of the most serious diseases that threaten human life and health. It is a major cause of death and disability in the clinic. New strategies for motor rehabilitation after stroke are undergoing exploration. We aimed to develop a novel artificial neural rehabilitation system, which integrates brain-computer interface (BCI) and functional electrical stimulation (FES) technologies, for limb motor function recovery after stroke. We conducted clinical trials (including controlled trials) in 32 patients with chronic stroke. Patients were randomly divided into the BCI-FES group and the neuromuscular electrical stimulation (NMES) group. The changes in outcome measures during intervention were compared between groups, and the trends of ERD values based on EEG were analyzed for BCI-FES group. Results showed that the increase in Fugl Meyer Assessment of the Upper Extremity (FMA-UE) and Kendall Manual Muscle Testing (Kendall MMT) scores of the BCI-FES group was significantly higher than that in the sham group, which indicated the practicality and superiority of the BCI-FES system in clinical practice. The change in the laterality coefficient (LC) values based on μ-ERD (ΔLC

Total phenolic extract of Euscaphis konishii hayata Pericarp attenuates carbon tetrachloride (CCl4)-induced liver fibrosis in mice.

Liver fibrosis is a crucial pathological process involved in the hepatogenic morbidity and mortality. The pericarp of Euscaphis konishii Hayata is usually used in the cooking soup to improve liver function in Southern China, and high level of phenolic compounds has been found in the E. konishii pericarp. The total phenolic compounds extracted from E. konishii pericarp (TPEP) was obtained by polyamide column chromatograph, and 9 phenolic compounds of TPEP were identified through LC/MS and NMR. TPEP exhibited strong free radicals scavenging activity in vitro, and the chronic CCl4-induced liver fibrosis mice were established to elucidate the hepatoprotective mechanism of TPEP in vivo. TPEP treatment (50, 100 and 200 mg/kg) ameliorated the oxidative stress, immune dysfunction, inflammatory response and hepatic fibrosis induced by CCl4 introduction, alleviated the histopathological alteration and hepatocyte apoptosis in the liver tissue. Pretreatment with TPEP suppressed the activation of NADPH oxidase (NOX) signaling to attenuate oxidative stress in the liver tissue. TPEP administration inhibited the translocation of NF-κB into the nucleus to prevent the expression of downstream proinflammatory cytokines. TPEP treatment downregulated the activation of TGF-ß/Smad pathway, and facilitated the degradation of extracellular matrix through enhancing matrix metalloproteinases (MMPs) activity and decreasing the expression of matrix metalloproteinase inhibitors (TIMPs). In conclusion, TPEP inhibited CCl4-induced hepatic fibrosis through its antioxidant, anti-inflammatory and anti-fibrotic activities.

Compared with EA, warm needling moxibustion shows advantage in both short-term and long-term efficacies, and thus is worth promotion in clinical practice.

Recent highlights of Chinese herbs in treatment of allergic disease: Acting via mitogen-activated protein kinase signal pathway / 中国结合医学杂志

The histamine receptor antagonists in the treatment of allergic disease have limitations. The treatments of Chinese herbs have some curative effects on allergic skin lesions. Present research indicates that the mitogen-activated protein kinase (MAPK) signaling pathway might be equally important in allergic reactions. It was found that the inhibition of MAPK signaling pathways might relieve allergy symptoms, and some herbs can inhibit the MAPK pathway, which yields anti-allergy effects. Chinese medicines (CMs) have immense potential in the development of treatments for allergic disease.

Anti-inflammatory and analgesic effects of Bi-yuan-ling granules / 华中科技大学学报（医学）（英德文版）

Bi-yuan-ling granule (BLG) is a traditional Chinese medicine compound composed mainly of baicalin and chlorogenic acid. It has been demonstrated to be clinically effective for various inflammatory diseases such as acute rhinitis, chronic rhinitis, atrophic rhinitis and allergic rhinitis. However, the underlying mechanisms of BLG against these diseases are not fully understood. This study aimed to explore the anti-inflammatory and analgesic activities of BLG, and examine its protective effects on mouse acute lung injury (ALI). The hot plate test and acetic acid-induced writhing assay in Kunming mice were adopted to evaluate the pain-relieving effects of BLG. The anti-inflammatory activities of BLG were determined by examining the effects of BLG on xylene-caused ear swelling in Kunming mice, the cotton pellet-induced granuloma in rats, carrageenan-induced hind paw edema and lipopolysaccharide (LPS)-induced acute lung injury (ALI) in mice. The results showed that BLG at 15.5 mg/g could significantly relieve the pain by 82.5% (P<0.01) at 1 h after thermal stimulation and 91.2% (P<0.01) at 2 h after thermal stimulation. BLG at doses of 7.75 and 15.5 mg/g reduced the writhing count up to 33.3% (P<0.05) and 53.4% (P<0.01), respectively. Additionally, the xylene-induced edema in mice was markedly restrained by BLG at 7.75 mg/g (P<0.05) and 15.5 mg/g (P<0.01). BLG at 5.35 and 10.7 mg/g significantly reduced paw edema by 34.8% (P<0.05) and 37.9% (P<0.05) at 5 h after carrageenan injection. The granulomatous formation of the cotton pellet was profoundly suppressed by BLG at 2.68, 5.35 and 10.7 mg/g by 15.4%, 38.2% (P<0.01) and 58.9% (P<0.001), respectively. BLG also inhibited lung W/D ratio and the release of prostaglandin E2 (PGE2) in ALI mice. In addition, the median lethal dose (LD50), median effective dose (ED50) and half maximal inhibitory concentration (IC50) of BLG were found to be 42.7, 3.2 and 12.33 mg/g, respectively. All the findings suggest that BLG has significantly anti-inflammatory and analgesic effects and it may help reduce the damage of ALI.
